A. CM.Goal 1. Conserve lands which provide valuable natural mineral deposits for potential future use in accordance with state law. 1. CM.Policy 1.1. Access to future mineral resource development areas should be considered in all land use decisions in accordance with state law. No County governmental authority which has control over zoning shall, by zoning, rezoning, granting a variance or other official action or inaction, permit the use of any area known to contain a commercial mineral deposit in a manner which would interfere with the present or future extraction of such deposit by an extractor. Acknowledged. • B. CM.Goal 2. Promote the reasonable and orderly development of mineral resources. 1. CM.Policy 2.1. The operation of a mine site in unincorporated Weld County shall be subject to obtaining a specialized Use By Special Review Permit in accordance with Chapter 23 of this Code. Acknowledged. C. CM.Goal 3. Minimize the impacts of surface mining activities on surrounding land uses, roads and highways. 1. CM.Policy 3.1. An application for a mine site located within the County should be reviewed in accordance with the goals and policies of the area in which the application is located. 2. CM.Policy 3.2. An application for a mine site will be reviewed in consideration of the cumulative impacts of the mining activity on surrounding land use and County infrastructure. • Varra Companies, Inc. Weld County USR Western Sugar Reclamation Land Development Project November 2010 Acknowledged. • D. CM.Goal 4. Minimize hazardous conditions related to mining activities and the mining site. 1. CM.Policy 4.1. In reviewing the operational and reclamation plans for a mining operation, the County should impose such conditions as necessary to minimize or eliminate the potential adverse impact of the operation on surrounding properties as follows: a. CM.Policy 4.1.1. Require the location and design of excavated areas, structures, machinery, equipment storage and stockpiling of mined materials to be compatible with surrounding land uses in terms of general use, scale, density, traffic, dust and noise. The genesis of the location is associated with the rise of sugar beet agriculture. Sugar beets were first grown in Colorado in 1869, one year before members of a joint—stock colonization company called the Union Colony of Colorado founded the City of Greeley. By • 1879, the state's agricultural college (later, Colorado State University) confirmed the compatibility of the area soils for sugar beet production. As Colorado's mining industry declined in the 1880's, farming in Weld County flourished. Beet processing began in Grand Junction in 1899. Great Western Sugar Company was founded in 1903 and built two plants, one in Loveland and one in Greeley. The company was incorporated in 1905 and by 1906 beet sugar factories had been constructed in Rocky Ford, Loveland, Greeley, Eaton, Fort Collins, Longmont, Windsor, Sterling, Fort Morgan and Brush. Aerial images from the early 1950's show cattle operations over the parcel presently within the city limits of Greeley. The Weld County portion designated for extraction was used for irrigated pasture. By the mid 1970's, basins were in use on the lower half of the former pasture land. Cattle operations appeared to have been discontinued by the mid to late 1980's, or about the time the company was acquired by Tate and Lyle. • Varra Companies, Inc. Weld County USR 2 Western Sugar Reclamation Land Development Project November 2010 A pivot irrigation system was in operation over a portion of the • northern pasture by 1989. Irrigation appears to have been discontinued by the end of the 1990's, and the former pasture lands and remaining basins turned to weed. Operations at the sugar factory continued, using the basins on the proposed areas of extraction to settle out beet waste from processing. On-going operations of the sugar mill into the twenty-first century eventually fell into question. In 2002 to the grower owned Western Sugar Cooperative acquired the sugar mill and lands from Tate and Lyle; but operations continued to decline. By 2007, the former sugar mill and its lands were reported as blighted in the Greeley Tribune. The lands were acquired from the Cooperative in August 2007 by Varra Companies, Inc., the present owner; who has since retained the lands east of Ash Avenue; while Leprino Foods acquired the lands west of Ash Avenue, where the old mill stood until it was demolished in 2008-2009. By this submittal, the owner proposes to reclaim the formerly • blighted and neglected lands through extracting the underlying aggregate and reclaiming the resulting basins for water storage. All formerly blighted lands reaffected by planned activities and remaining above the anticipated static water level of the resulting reservoirs will be returned to a beneficial and stabilizing cover of predominantly native vegetation; except where existing access roads, structures or other reasonable obstacles prevent it. Under Title 34, the State of Colorado and Weld County require the removal of a valuable mineral deposit from those lands prior to development. The act of resource recovery and resulting end use is allowable under the Weld County zoning designation of the I-3 Industrial District; which applies to the entire lands considered under this application. The extraction is necessary to attain both the resource and end use objectives. Both extraction and the resulting basins are fully compatible with the surrounding lands. The planned activities over the formerly blighted lands will return them to a beneficial use, resulting in improved visual and fiscal enhancement to both the principle and surrounding land owners. Varra Companies, Inc. Weld County USR 3 Western Sugar Reclamation Land Development Project November 2010 • The location is flanked on the east and south by properties in the A-Agriculture Zone. Southeast of planned extraction homes lie slightly farther away from operational activity than they are for existing permitted extraction activity to their immediate north. South of the planned extraction homes line 16th Street more than 400 feet from planned extraction or plant activities. Noise emanating from an 80 decibel source (e.g., a cone crusher) would be background residential level or 55 decibels by the time it reaches 400 feet from the source. For the nearest residence to the southeast, extraction would not reach within four hundred feet until near the end of extraction operations, and again, would be slightly further away than activities at an existing operation to the immediate north of this residence. With the exception of this one residence, all other sources are completely out of reach of any industrial noise levels, which operations are not anticipated to exceed. Each existing residence within the designated A-Agriculture zone is surrounded by trees • and open space separating their residence from operations within the adjacent I-3 zone. City of Greeley - Industrial I-NI (medium intensity) lands lie to the north and west of the permit boundary. These lands are either vacant, or bounded by land disturbances such as settling basins, waste piles, or industrial buildings and support facilities or equipments. Other existing mining operations flank the permit boundary to the north and east. Planned activities within the permit boundary will not interfere with any of the surrounding Industrial lands or their current activities. Agricultural stock ponds, land leveling, use of equipment to manipulate land for crops, and other agricultural based activities are not uncommon in agricultural locations. As shown on the included Colorado Division of Reclamation Mining and Safety (CDRMS), Office of Mined Land Reclamation (OMLR) Exhibit C-2: Extraction Plan Map, the greater concentration of plant and processing activity, parking, machinery and equipment storage and stockpiling of materials is located in a manner that is removed from area residences and muted by area trees, open space and hillsides in the Varra Companies, Inc. Weld County USR 4 Western Sugar Reclamation Land Development Project November 2010 form of the flood plain escarpment. The location is approached • internally and away from high density residential areas and roads. Unlike other urban uses that intrude upon the agricultural districts, extraction is a transitional use that leaves the final land in a configuration that prevents future high density urban development, common to residential subdivision for example. The resulting basins create visual and functional amenities that harmonize the scale, function, and vistas of surrounding lands, uses, and habitats. While residential development fragments wildlife habitat with increasingly larger building footprints for dwellings, along with incompatible landscapes and fence-works; the results following extraction typically do not result in such permanent diminished landscapes, habitats or densities. Many active operations serve to increase wildlife diversity and use that is otherwise crowded out by urban development, hence providing critical corridors, habitat, and protection for diverse wildlife species that would otherwise be lost. Often, the post mine landscape offers an obvious enhancement that might not otherwise be realized, especially over blighted or neglected lands such as these. The reclamation of extracted lands in fact often incorporates or introduces concepts commonly lacking in urban development. The more open design elements include the creation of edge effect resulting from the reintroduction of a more diverse and native landscape, often incorporating enhanced aquatic margins that better complement wildlife and scenic values. Overall, final reclamation of the extracted lands create features that better lend themselves to the visual enjoyment by the surrounding community. The Vicinity Map shows those properties currently under permitted extraction, or otherwise owned or leased by companies that will eventually open those lands to extraction. The proposal complements the Agricultural A District, and nearby Industrial and Conservation Districts designated by the City of Greeley. Resource recovery simply cannot occur over lands developed with houses and other structures. The difficulty is compounded by the expedient placement of oil and gas wells, lines, and facilities over alluvial formed aggregate resources, in • contradiction with Title 34. Where extraction occurs, the former Varra Companies, Inc. Weld County USR 5 Western Sugar Reclamation Land Development Project November 2010 agricultural-industrial land base will be replaced in part with water • resources; a vital element of continued agricultural practices on surrounding lands, and for the ever increasing urban population and uses expanding into the Agricultural A District of Weld County. b. CM.Policy 4.1.2. Maintain roadside and perimeter vegetation and setback requirements which serve to shield mining operations, including storage of equipment, stockpiled soils and materials from public view. General buffering or screening will not occur in this setting during the extraction process. The site is located below an escarpment, above which lie the A-Agriculture lands. The residential homes closest to these lands lay further back along adjacent urban roadways and are generally out of view of operations. The surrounding Industrial lands are impacts in their own right and will not be affected by planned activities. The planned activity is consistent with two adjacent existing mining operations to the • immediate north and east of the permit boundary. All lands re- affected by operations within the designated permit area remaining above the static water level of the basins, except where existing access roads, structures or other reasonable obstacles prevent it, will be vegetated with the approved grass mixture, as detailed under the OMLR Permit Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture. c. CM.Policy 4.1.3. Require that access roads to and within the site be located in a manner which minimizes traffic impacts on surrounding land uses. Primary access into the project location is from Ash Avenue, through Varra Companies, Inc. lands flanking the western permit boundary, and into the location from an existing access road. While existing agricultural access are preserved as secondary or emergency access for personnel and the landowners/users, all visitors and laborers will utilize the primary access. • Varra Companies, Inc. Weld County USR 6 Western Sugar Reclamation Land Development Project November 2010 Employee parking will be flexible to better accommodate internal • operations as necessary respective of the extraction, transport, communication and maintenance of extraction activities and equipment, and for the necessary access by authorized personnel or support services. Visitor parking will be directed to the scale house or otherwise restricted by signage. All Varra Company, Inc. personnel are encouraged to observe WCR speed limits in established company safety policy. Posted speed limits of 15 mph will be evident along the primary access road, or as otherwise determined in cooperation with U.S. MSI-IA requirements. Minimum specification of access where they meet Weld County roads, as specified in Part 9, below, will be honored, however, no Weld County roads are accessed from the primary access road under this application. d. CM.Policy 4.1.4. Require the land use applicant to demonstrate to the satisfaction of the Board of County Commissioners that the street or highway facilities providing access to the mining • activity are adequate in functional classification, width and structural capacity to meet the requirements of the proposed mining activity. Internal road circulation, off-street parking, dust abatement, acceleration lanes, deceleration lanes, common access collection points, signalization and other traffic improvements shall be required wherever necessary to mitigate traffic impacts caused by the mining activity. Applications for mining should also be reviewed in accordance with the transportation goals and policies. The primary access enters City of Greeley, Colorado jurisdiction. e. CM.Policy 4.1.5. Require, where possible, that batch plants and processing equipment be buffered from adjacent uses. Any planned processing or plant facilities will be located 400.0± feet or greater from any public road or existing residence not • owned or controlled by the applicant, minimizing the effects of Varra Companies, Inc. Weld County USR 7 Western Sugar Reclamation Land Development Project November 2010 facility noise on area residents. At 400± feet or greater from a known source of 80± decibels (db), measured noise levels are at background residential, or 55± db. Further, any plant activities will be situated north of the floodplain escarpment flanking them to the east and south as shown on OMLR Exhibit C-2: Extraction Plan Map. The location of plant related activity below the escarpment terrace will further assure diminished impact from noise and visual effects on nearby residences. Adjacent industrial lands will not be impacted by plant activities. f. CM.Policy 4.1.6. Require appropriate security fencing be erected and maintained around extraction sites, as necessary, to minimize the attractive nuisance hazards inherent in operations located near urban uses. The property is surrounded by fencing south of the Cache La Poudre River, with steel gates securing all entrances. Repairs will • be made as needed to downed fence prior to onset of extraction activities. All repairs will meet or exceed the nature of the existing fence, which varies according to the adjacent landowners. All gates are locked when personnel are absent from the location to better discourage unauthorized access. g. CM.Policy 4.1.7. Require mining operations to use warning signs, fences, guards, lighting and other means to warn and protect people from mine site hazards such as steep slopes, holes, ponds and heavy equipment. All on-site safety and required signage will comply with the requirements of the United States Mine, Health and Safety Act (MSIIA) and attending regulations and requirements, and correlated response to MSIIA inspections. All access requirements of Weld County Public Works will also be maintained to a minimum with those standards set forth in Sec. 23-2-240 (9) Design Standards, below. • Varra Companies, Inc. Weld County USR 8 Western Sugar Reclamation Land Development Project November 2010 • h. CM.Policy 4.1.8. Require all mining operations conform to federal, state and local environmental standards. Acknowledged and supported by Exhibit M — Other Permits, of the OMLR permit. E. CM.Goal 5. Provide for timely reclamation and reuse of mining sites in accordance with this Chapter and Chapters 23 and 24 of this Code. 1. CM.Policy 5.1. The County should consider the potentially adverse environmental effects of mining operations. a. Disturbance of vegetation and overburden in advance of mining activities should be minimized. The planned extraction provides for concurrent reclamation of extracted lands as described under OMLR Exhibit D — Extraction • Plan and Exhibit E — Reclamation Plan. Regardless of the rate in which lands are opened for extraction, reclamation must follow concurrently behind. In this manner, the productivity, stability, life of the operations, and post extraction development timelines are optimized. Since the lands are blighted, the act of extraction, basin creation, and resulting reclamation functions to return previously impacted and heavily disturbed lands to a higher beneficial use. b. Topsoil should be saved and utilized in site reclamation. c. All reasonable and practical measures should be taken to protect the habitat of fish and wildlife. Sufficient and suitable soil will be set in reserve for the reclamation and all formerly blighted lands reaffected by planned activities and remaining above the anticipated static water level of the resulting reservoirs will be returned to a beneficial and stabilizing cover of predominantly native vegetation; except where existing access roads, structures or other reasonable obstacles prevent it, as detailed in OMLR Exhibit D — Extraction Plan, OMLR Exhibit E — Varra Companies, Inc. Weld County USR 9 Western Sugar Reclamation Land Development Project November 2010 Reclamation Plan and Exhibit I/J - Soils and Vegetation Information. • While residential development fragments wildlife habitat with increasingly larger building footprints for dwellings, along with incompatible landscapes and fence-works; the results following extraction typically do not result in such permanent diminished landscapes, habitats or densities. Many active operations serve to increase wildlife diversity and use that is otherwise crowded out by urban development, hence providing critical corridors, habitat, and protection for diverse wildlife species that would otherwise be lost. Often, the post mine landscape offers an obvious enhancement that might not otherwise be realized, especially over blighted or neglected lands such as these. d. The operation should comply with County flood hazard and geological hazard regulations. There are no geological hazards at this location. The location lies • within the 100 year floodplain and a designated floodway of the Cache La Poudre River. No stockpiles will occur within the floodway that would raise existing elevations greater than one foot in height. No buildings are planned within the floodplain/floodway. All plant facilities and fueling activities are portable. No permanent on-site fuel or chemical storage facilities are anticipated or planned within the floodplain/floodway. e. The operator will maintain the reclaimed mine site until it has been stabilized and vegetation is reestablished. Colorado Office of Mined Land Reclamation [OMLR] rules and regulations, under C.R.S. 34-32.5-101, require that all effects of extraction on affected lands be maintained in a manner that provides for on-site stability during the operational life, minimizes impacts to off-site locations, and reclaims the affected lands to beneficial uses to the extent required under an approved and bonded OMLR permit which the applicant must secure prior to on-set of extraction activity. The planned reclamation is identified under OMLR Exhibit Varna Companies, Inc. Weld County USR 10 Western Sugar Reclamation Land Development Project November 2010 E - Reclamation Plan, Exhibit F - Reclamation Plan Map, and Exhibit • L - Table L-1: Primary/Preferred Seed Mixture. f. Trucking operations dealing exclusively in the transport of mined materials may be permitted on the mine site when incorporated in the operational plan for the mining operation. F. CM.Goal 6. The extraction of mineral resources should conserve the land and minimize the impact on surrounding land. (Weld County Code Ordinance 2002- 6) The extraction of aggregate mineral resources is acknowledged by both the State of Colorado and Weld County as a conservation practice, as indicated in CM. Policy 1.1, and more specifically under C.R.S. 34-1-305. The extraction of aggregate resource and resulting reclamation tends to lessen the future density of subsequent urban development spawned by the inevitable expansion of human habitat, supporting uses, facilities and infrastructure. It is in fact this existing and ever expanding urbanization of agricultural land that constitutes the greatest demand for this nonrenewable resource. Section 22-5-80 of Weld County's Code of Regulations is consistent with Colorado law, both of which require that this resource must be recovered prior to other development which would otherwise impede access to it. The subsequent development of a diverse multiple land use potential at this location, when complemented with sound environmental parameters, as advanced under this proposal and the attending OMLR permit exhibits, is in keeping with the spirit and intent of the policies and goals of Weld County. Approval of the application will allow the resource to be accessed and utilized in a reasonable and orderly manner as required under both Colorado law and the Weld County Code of Regulations. Planning for the extraction of the aggregate resources takes into account the optimal protection of the soil resource, avoidance and minimization of impacts on area wetlands, and otherwise from potential impacts due to noise, dust, water discharge, traffic, or other operational effects to the surrounding community, as detailed in this application, and in the included and publicly available OMLR permit application, attending exhibits, and correlated permitting requirements (refer to OMLR Exhibit M - Other Permits). The planned extraction and • resulting reclamation provided for under the OMLR permit will serve to reclaim Varra Companies, Inc. Weld County USR 11 Western Sugar Reclamation Land Development Project November 2010 the previously blighted and heavily disturbed lands of the old Western Sugar • facilities to a higher beneficial use. The higher use will add value to the immediate and surrounding lands, and the area at large. • • Varra Companies, Inc.

Uses by Special Review are USES which have been determined to be more intense or to have a potentially greater impact than the Uses Allowed By Right in a particular zone district. Therefore, Uses by Special Review require additional consideration to ensure that they are established and operated in a manner that is compatible with existing and planned land USES in the NEIGHBORHOOD. The additional consideration or regulation of Uses by Special Review is designed to protect and promote the health, safety, convenience and general welfare of the present and future residents of the COUNTY. B. The Board of County Commissioners may approve the establishment of a Use by Special Review by granting a Special Review Permit. All requests for Special Review Permit shall be reviewed by the Planning Commission. The Planning Commission recommendation shall be forwarded to and considered by the Board • of County Commissioners except for the following conditions. Any DEVELOPMENT or USE which requires a Special Review Permit and which is initiated by a general purpose local government, State, United States government, special district or authority created under the provisions of the laws of the State, or any public utility whether publicly or privately owned, shall require review and approval by the Planning Commission only as set forth in Division 5 below. C. Any person filing an application for a Special Review Permit shall comply with the COUNTY procedures and regulations as set forth herein. Any expansion or enlargement of a Use by Special Review shall be treated as a new USE and shall require a new application under the provisions of this Division. D. Ordinary repairs and maintenance may be performed upon STRUCTURES associated with a Use by Special Review so long as such repairs and maintenance do not have the effect of expanding or enlarging the USE. E. If the Use by Special Review has not commenced within three (3) years from the date of approval or is discontinued for a period of three (3) consecutive years, it shall be presumed inactive. The COUNTY shall initiate an • administrative hearing to consider whether to grant an extension of time to Varra Companies, Inc. Weld County USR 13 Western Sugar Reclamation Land Development Project November 2010 commence the use or revoke the Use by Special Review. If the Use by Special • Review is revoked, it shall be necessary to follow the procedures and requirements of this Section in order to reestablish any Use by Special Review. F.

The Planning Commission shall hold a hearing to consider the application for the Special Review Permit. The public hearing may involve either the Special Review Permit application alone or may include the review of concurrent applications under the COUNTY's provisions for Overlay Districts Regulations in Article V of this Chapter. The Planning Commission shall provide recommendations to the Board of County Commissioners concerning the disposition of the requested Special Review Permit. The Planning Commission shall approve the request for the Special Review Permit only if it finds that the • applicant has met the standards or conditions of this Subsection A and Sections 23-2-240 and 23-2-250 of this Division. The applicant has the burden of proof to show that the standards and conditions of this Subsection A and Sections 23- 2-240 and 23-2-250 are met. The applicant shall demonstrate: 1. That the proposal is consistent with Chapter 22 of this Code and any other applicable code provision or ordinance in effect. The project conforms with Section 22-5-80 of Weld County's Comprehensive Plan: Commercial and Mineral Resource Deposits Goals and Policies. Expansion of human habitat and related pressures on area infrastructure is already evident near this location. The City of Greeley borders the project location to the west and north. Industrial expansion is underway with site preparation for a new Leprino Cheese Plant and other industrial development to the West. While residential homes are bounded by significant open space from their A-Agricultural standing, residential densities appear to increase approximately one-half mile beyond the permit area to the south, and east into the city. • Varra Companies, Inc. Weld County USR 18 Western Sugar Reclamation Land Development Project November 2010 The entire state of Colorado continues to be challenged by human • migration to the state, and the resulting urban development is shaping State policies to enhance area infrastructure, including the enhancements of area roadways along and either side of Interstate 25 and Colorado Ilighway 85, for which this location is ideally situated to serve. With continued growth of human habitat and development, the products that serve the construction of this infrastructure comes from the ground. The aggregate resource must be recovered before it is overtaken by ever expanding urban development, or it is lost. Now is the time and this is the geologically determined and economically feasible location from which the proposed extraction activity must occur. The extraction of aggregate resource is in fact resource conservation, and tends to lessen the future density of subsequent urban development resulting from the inevitable expansion of human habitat, supporting uses, facilities and infrastructure. It is in fact this existing and ever expanding urbanization of agricultural land that constitutes the greatest demand for this nonrenewable resource. • Section 22-5-80 of Weld County's Code of Regulations is consistent with Colorado law, both of which require that this resource must be recovered prior to other development which would otherwise impede access to it. The subsequent development of a diverse multiple land use potential at this location, when complemented with sound environmental parameters, as advanced under this proposal and the attending OMLR permit exhibits, is in keeping with the spirit and intent of the policies and goals of Weld County. Approval of the application will allow the resource to be accessed and utilized in a reasonable and orderly manner as required under both Colorado law and the Weld County Code of Regulations. 2. That the proposal is consistent with the intent of the district in which the USE is located. Under Title 34, the State of Colorado and Weld County require the removal of a valuable mineral deposit from those lands prior to development. The extraction of a mineral deposit is an allowable use within the Weld County Industrial I-3 District; which applies to the entire • Varra Companies, Inc. Weld County USR 19 Western Sugar Reclamation Land Development Project November 2010 lands considered under this application. Resource recovery simply cannot • occur over lands developed with houses and other structures. By this submittal, the owner proposes to reclaim formerly blighted and neglected lands through extracting the underlying aggregate and reclaiming the resulting basins for water storage. All previously affected lands reaffected by planned activities and remaining above the anticipated static water level of the resulting reservoirs will be returned to a beneficial and stabilizing cover of predominantly native vegetation; except where existing access roads, structures or other reasonable obstacles prevent it. The extraction is necessary to attain both the resource and end use objectives. Both extraction and the resulting basins are fully compatible with the surrounding lands. The planned activities over the formerly blighted lands will return them to a beneficial use, resulting in improved visual and fiscal enhancement to both the principle and surrounding land owners. • 3. That the USES which would be permitted will be compatible with the existing surrounding land USES. The planned activities complement the surrounding City of Greeley Industrial uses to the west and north, including existing mining operations to the north and east. The location is flanked on the east and south by properties in the A-Agriculture Zone. Southeast of planned extraction homes lie slightly farther away from operational activity than they are for existing permitted extraction activity to their immediate north. South of the planned extraction homes line 16'11 Street more than 400 feet from planned activity. Noise emanating from an HO decibel source (e.g., a cone crusher) would be background residential level, or 55 decibels by the time it reaches 400 feet from the source. For the nearest residence to the southeast, extraction would not reach within four hundred feet until near the end of extraction operations, and again, would be slightly further away than activities at an existing operation to the immediate north of this residence. The residence is heavily buffered by a dense line of trees and shrubs between the permit • area and the structure. Varra Companies, Inc. Weld County USR 20 Western Sugar Reclamation Land Development Project November 2010 • With the exception of this single residence, all other sources are completely out of reach of any potential industrial noise levels, which operations are not anticipated to exceed. Each existing residence within the designated A-Agriculture zone is surrounded by trees and open space, further separating their residence from operational effects within the adjacent 1-3 zone. City of Greeley - Industrial I-M (medium intensity) lands lie to the north and west of the permit boundary. These lands are either vacant, or bounded by land disturbances such as settling basins, waste piles, or industrial buildings and support facilities or equipments. Other existing mining operations flank the permit boundary to the north and east. Planned activities within the permit boundary will not interfere with any of the surrounding Industrial lands or their current activities. Agricultural stock ponds, land leveling, use of equipment to manipulate land for crops, and other agricultural based activities are not uncommon in agricultural locations. As shown on the included Colorado Division of Reclamation Mining and Safety (CDRMS), Office of Mined Land Reclamation (OMLR) Exhibit C-2: Extraction Plan Map, the greater concentration of plant and processing activity, parking, machinery and equipment storage and stockpiling of materials is located in a manner that is removed from area residences and muted by area trees, open space and hillsides in the form of the flood plain escarpment. The location is approached internally and away from high density residential areas and roads. 4. That the USES which would be permitted will be compatible with future development of the surrounding area as permitted by the existing zoning and with the future development as projected by Chapter 22 of this Code or MASTER PLANS of affected municipalities. The project conforms with Section 22-5-80 of Weld County's Comprehensive Plan: Commercial and Mineral Resource Deposits Goals and Policies. Expansion of human habitat and related pressures on area infrastructure is already evident near this location. • Varra Companies, Inc. Weld County USR 21 Western Sugar Reclamation Land Development Project November 2010 The extraction of aggregate resource is in fact resource conservation, and • tends to lessen the future density of subsequent urban development resulting from the inevitable expansion of human habitat, supporting uses, facilities and infrastructure. It is in fact this existing and ever expanding urbanization of agricultural land that constitutes the greatest demand for this nonrenewable resource. Section 22-5-80 of Weld County's Code of Regulations is consistent with Colorado law, both of which require that this resource must be recovered prior to other development which would otherwise impede access to it. The subsequent development of a diverse multiple land use potential at this location, when complemented with sound environmental parameters, as advanced under this proposal and the attending OMLR permit exhibits, is in keeping with the spirit and intent of the policies and goals of Weld County. Approval of the application will allow the resource to be accessed and utilized in a reasonable and orderly manner as required under both Colorado law and the Weld County Code of Regulations. The proposal complements the surrounding Industrial and Agricultural Districts. Resource recovery simply cannot occur over lands developed • with houses and other structures. Where extraction occurs, the formerly blighted landscape will be replaced with water resources. Unlike other urban uses that intrude upon the agricultural districts, extraction is a transitional use, that leaves the final land in a configuration that prevents high density urban development, common to residential subdivision for example. The resulting basins create visual and functional amenities that harmonize the scale, function, and vistas of surrounding agricultural lands and habitats. While residential development fragments wildlife habitat with increasingly larger building footprints for dwellings along with incompatible landscapes and fence-works; the results following extraction typically do not result in such permanent diminished landscapes, habitats or densities. The reclamation of extracted lands in fact often incorporate or introduce concepts often lacking in other developmental impacts. The more open design elements include the creation of edge effect resulting from the reintroduction of a more native landscape with enhanced aquatic margins that better complement and aid wildlife and scenic values. Overall, final reclamation of the extracted lands create features that better complement and lend themselves to the visual enjoyment of the • surrounding community. The Vicinity Map shows those properties Varna Companies, Inc. Weld County USR 22 Western Sugar Reclamation Land Development Project November 2010 currently under permitted extraction, or otherwise owned or leased by • companies that will eventually open those lands to extraction. The Future Compatibility: The resulting reservoirs foreseen under the reclamation plan will result in lower density development toward the Cache La Poudre River watershed. Agricultural conversion to other extraction and mixed industrial, commercial and residential uses are already evident as shown on the Vicinity Map. The water from the reservoirs can be made available for either urban or agricultural uses, but the basins alone are essential to providing a means to store and manage available waters. Any subsequent lower density development which may follow will still require necessary approvals from Weld County Building Department prior to the construction of any permanent structures, and from Weld County Planning, prior to the utilization of the parcels for any subsequent light residential, commercial or industrial uses beyond those already indicated under this submittal, and specifically indicated on OMLR Exhibit C-2: Extraction Plan Map. • 5. That the application complies with Article V of this Chapter if the proposal is located within the Overlay District Areas identified by maps officially adopted by the COUNTY. The location is outside of any known geologic hazard. The location is within the Weld County Airport `Influence Zone.' The project does lie within the floodplain and a portion of the defined floodway of the Cache La Poudre River. Operational effects should not adversely impact any of the designated overlays, floodway or floodplain. 6. That if the USE is proposed to be located in the A (Agricultural) Zone District, the applicant has demonstrated a diligent effort has been made to conserve PRIME FARMLAND in the locational decision for the proposed USE. The identified soils are not Prime Irrigated Soils as designated on the U.S.D.A. Map titled, Important Farmlands of Weld County. Since • extraction will result in basins and reclaimed to water storage reservoirs, Varra Companies, Inc. Weld County USR 23 Western Sugar Reclamation Land Development Project November 2010 the marginal soils overlying the aggregate resource will be salvaged and • set aside for reclamation to the extent necessary and prescribed under the approved ()MLR permit. Excess soil will be made commercially available. Replacement of the entire soil is not practical since resource recovery is dictated by the underlying deposit and the resulting basin area will generate more soil than is needed for the reaffected land remaining above the anticipated static water level of the basins and otherwise requiring revegetation. When considering that the project location will be reclaimed to higher end uses while making available the resource for raw construction materials, the loss of some soil is unavoidable for the sake of the greater infrastructure needs of the community. All soil will find a productive use, either in the reclamation of affected lands not otherwise occupied by on- site access or other uses, or by the ever increasing urban communities, or local agricultural base. For a more comprehensive treatment of how the project meets the other goals and policies of the Comprehensive Plan and surrounding uses, please refer to Sec. 23-2-260, below. • 7. That there is adequate provision for the protection of the health, safety and welfare of the inhabitants of the NEIGIIBORHOOD and the COUNTY. The location as it is extracted will by its nature diminish any potential for fire or flood to surrounding lands. The localized access surrounding the basins, and the extraction itself resulting in basins below original ground will serve to cause direct precipitation to drain internally or otherwise serve to route or divert external overland flows to existing waterways, and in general serve as a firebreak to surrounding lands. The nature of the extraction is intended to work the perimeters of the limits of extraction inward and away from area roadways and residences. By getting behind hillsides or below ground level, sounds from operations will be muted by the resulting topography. Internal access to operations is located below and away from nearby homes and area streets. Dust is minimized from leaving the project area by the extraction of moist materials in a project area managed under the authority of a Colorado Department of Health Fugitive Dust Permit. Waters are managed and Varra Companies, Inc. Weld County USR 24 Western Sugar Reclamation Land Development Project November 2010 protected under authority of the Colorado Department of I lealth • stormwater permit requirements and Colorado Division of Water Resources. Health and Safety on site personnel and visitors are managed under authority of the federal MSHA program. All planned extraction, reclamation, phasing, timelines, life of the mine and warranty considerations are regulated under the State of Colorado Division of Minerals and Geology, Office of Mined Land Reclamation (OMLR). Reclamation of affected lands follows closely behind extraction activities, as provided for under the Colorado Office of Mined Land Reclamation [OMLR] permit, and described in detail under OMLR Exhibit E - Reclamation Plan and Exhibit F - Reclamation Map, of that permit. Visual impacts during and subsequent to extraction and reclamation activities are cased by the location below and away from area residences and surrounded by existing or planned Industrial uses and activities. B. The Secretary of the Planning Commission shall forward the official recommendation of the Planning Commission and the information contained in the official record, which includes the Department of Planning Services case file, to the Clerk to the Board within ten (10) days after said recommendation has been made.

Ash Avenue to the west and the Cache La Poudre River to the north when combined with on site haul roads along the basin perimeters, and the seep ditch that bisects the property; function as fire breaks in the event of any potential grass fire. In general, the nature of the planned extraction activity will tend to reduce the potential for wildfire over the existing property by the removal of live plants and dead litter. Personnel are also trained under federal MSI IA requirements in fire safety. 5. USES shall comply with the following stormwater management standards: a. Stormwater retention facilities shall be provided on site which are • designed to retain the stormwater runoff from the fully developed site from a one-hundred-year storm or as otherwise required by the Department of Public Works. In the case of a LIVESTOCK CONFINEMENT OPERATION (L.C.O.), wastewater collection, conveyance and retention facilities shall be designed and constructed in accordance with the Confined Animal Feeding Operation Control Regulations (5 CCR 1002-19). As indicated in the included Stormwater Management Plan. b. The drainage facilities shall be designed to release the retained water at a quantity and rate not to exceed the quantity and rate of a five-year storm falling on the UNDEVELOPED site. During extraction activity, groundwater will be discharged into a nearby seep in order to maintain the resulting basin until completion • of reclamation of the basin for water storage. The location of the Varna Companies, Inc. Weld County USR 36 Western Sugar Reclamation Land Development Project November 2010 planned discharge locations are shown on OMLR Exhibit C-2: • Extraction Plan. Groundwater discharge is provided for under an approved stormwater discharge permit issued by the Colorado Department of Health. The intersecting seep and surrounding drainageways form an existing barrier to the transportation of intercepted direct precipitation, and tend to limit the introduction of waters from essentially non-existent overland flows from any upland watershed. The majority of any upland water will flow into and around the location along existing channels, or otherwise be intercepted by other unaffected channels, including the existing seep ditch. The extraction of materials will cause direct precipitation to drain internally toward the resulting basins. Above basin portions of the operation, including any plant site, stockpiles, haul roads, and other operational features are located on existing or excavated near table topography. All on-site drainage is managed under an approved Stormwater Management Plan. • 6. All parking and vehicle storage shall be provided on the site; parking shall not be permitted within any public right-of-way. An adequate parking area shall be provided to meet the parking needs of employees, company vehicles, visitors and customers. Parking will be commonly limited to the plant and stockpile area identified on OMLR Exhibit C-2: Extraction Plan Map, except where internal operations are necessary to the extraction, transport, communication and maintenance of extraction activities and equipment, and for the necessary access by authorized personnel or support services. Employee parking will be flexible to better accommodate internal operations as necessary respective of the extraction, transport, communication and maintenance of extraction activities and equipment, and for the necessary access by authorized personnel or support services. Visitor parking will be directed to the scale house or otherwise restricted by signage. 7. The USE shall comply with all the SETBACK and OFFSET requirements • of the zone district. Varra Companies, Inc. Weld County USR 37 Western Sugar Reclamation Land Development Project November 2010 • Acknowledged and provided for. Extraction and processing will be no closer than 10.0± feet from any structure, easement or right-of-way, and no closer than 125.0± feet from the exterior of any residence not owned or controlled by the operator (refer to the Vicinity Map and OMLR Exhibit C-2: Extraction Plan Map. 8. The access shall be located and designed to be safe; ingress and egress shall not present a safety hazard to the traveling public or to the vehicle accessing the property. For USES generating high traffic volumes and large number of large, slow—accelerating vehicles, acceleration and deceleration lanes may be required to mitigate a potential traffic hazard. The location of the designated primary access road will tend to minimize the use of area residential roads. Ash Avenue as it flanks the west boundary of the project connects the several existing and potential • industrial uses and zones between 8`h and 16th Streets where heavy haulers commonly utilize as a means to and from those uses and access to and from Colorado Highway 85 to the west. While existing agricultural access are preserved as secondary access for senior personnel and the landowners/users, all visitors and laborers will utilize the primary access. Parking will be commonly limited to the plant and stockpile area identified on OMLR Exhibit C-2: Extraction Plan Map, except where internal operations are necessary to the extraction, transport, communication and maintenance of extraction activities and equipment, and for the necessary access by authorized personnel or support services. Employee parking will be flexible to better accommodate internal operations as necessary respective of the extraction, transport, communication and maintenance of extraction activities and equipment, and for the necessary access by authorized personnel or support services. Visitor parking will be directed to the scale house or otherwise restricted by signage. All Varra Company, Inc. personnel are encouraged to observe area speed limits in established company safety policy. Posted speed limits of 15 mph will be evident along the primary access road, or as otherwise determined in cooperation with U.S. MSIIA requirements. Minimum specification of access where they meet Weld County roads, as specified in Part 9, below, • will be honored. Varra Companies, Inc. Weld County USR 38 Western Sugar Reclamation Land Development Project November 2010 9. New accesses to public rights-of-way shall be constructed using the following as minimum standards: a. Size of drainage structure — twelve (12) inches in diameter. b. Length of drainage structure — twenty (20) feet. c. Depth of cover over pipe - twelve (12) inches. d. Width of access - fifteen (15) feet. e Maximum grade of access - fifteen percent (15%). f. Flare radius - twenty (20) feet. g. Depth of surfacing — four (4) inches. Standards exceeding these minimums may be required depending on the type and volume of vehicles generated by the type of USE proposed. The above minimum standards will be applied where necessary, however, there is no new access to public rights-of-way under this application, and none which enter onto Weld County roads as Ash Street is within the city limits of Greeley. There are existing points of internal access which will be upgraded to meet the needs turning semi truck and trailer combinations • and other heavy equipment transport to and from the project location. The primary access is shown on OMLR Exhibit C-2: Extraction Plan Map. 10. Buffering or SCREENING of the proposed USE from ADJACENT properties may be required in order to make the determination that the proposed USE is compatible with the surrounding uses. Buffering or SCREENING may be accomplished through a combination of berming, landscaping and fencing. Planning for extraction commonly incorporates existing or created vegetated buffers to complement adjacent lands and uses. Existing trees and ground cover along public road frontage and drainage ways will be preserved, maintained, and supplemented where necessary to aid in the stability of perimeter lands and minimize operational impacts. The very nature of reclamation of these lands results in open spaces, diverse but less dense end uses, and complementary transitional vegetation that does not obstruct or conflict, but in fact complements, the surrounding lands and area wildlife. Varra Companies, Inc. Weld County USR 39 Western Sugar Reclamation Land Development Project November 2010 General buffering or screening will not occur during the extraction • process, since the site lies below area homes and agricultural yards, while otherwise surrounded by more intensive industrial uses to the north and west of the location. There are also existing and on-going mining operations to the immediate east and north of the permit boundary. Any planned processing or plant facilities will be located 400.0± feet or greater from any area road or existing residence not owned or controlled by the applicant, minimizing the effects of facility noise on area residents. At 400± feet or greater from a known source of 80± decibels (db), measured noise levels are at background residential, or 55± db. 11. Uses by Special Review in the A (Agricultural) Zone District shall be located on the least prime soils on the property in question unless the applicant can demonstrate why such a location would be impractical or infeasible. The identified soils are not Prime Irrigated Soils as designated on the • U.S.D.A. Map titled, Important Farmlands of Weld County. Since extraction will result in basins and reclaimed to water storage reservoirs, the marginal soils overlying the aggregate resource will be salvaged and set aside for reclamation to the extent necessary and prescribed under the approved OMLR permit. Excess soil will be made commercially available. Replacement of the entire soil is not practical since resource recovery is dictated by the underlying deposit and the resulting basin area will generate more soil than is needed for the reaffected land remaining above the anticipated static water level of the basins and otherwise requiring revegetation. When considering that the project location will be reclaimed to higher end uses while making available the resource for raw construction materials, the loss of some soil is unavoidable for the sake of the greater infrastructure needs of the community. All soil will find a productive use, either in the reclamation of affected lands not otherwise occupied by on- site access or other uses, or by the ever increasing urban communities, or local agricultural base. For a more comprehensive treatment of how the project meets the other goals and policies of the Comprehensive Plan and surrounding uses, please refer to Sec. 23-2-260, below. • Varra Companies, Inc. Weld County USR 40 Western Sugar Reclamation Land Development Project November 2010 B. If the Special Review Permit for a MAJOR FACILITY OF A PUBLIC UTILITY OR PUBLIC AGENCY is approved, the Planning Commission shall arrange for the Department of Planning Services to record the appropriate Facilities Plan, Utility Line or Selected Route Map with the County Clerk and Recorder. (Weld County Codification Ordinance 2000-1) This section does not appear applicable to the planned project activities. Sec. 23-2-250. Operation Standards. An applicant for a Special Review Permit shall demonstrate conformance with the following operation standards in the Special Review Permit application to the extent that the standards affect location, layout and design of the Use by Special Review prior to construction and operation. Once operational, the operation of the USES permitted shall conform to these standards. A. The operation of the USES shall comply with the noise standards enumerated in Section 25-12-101, C.R.S. Any planned processing or plant facilities will be located 400.0± feet or greater from any county road, or existing residence not owned or controlled by the applicant, minimizing the effects of facility noise on area residents. At 400± feet or greater from a known source of 80± decibels (db), measured noise levels are at background residential, or 55± db. By example: On 28 August 1998, using a hand held decibel meter, on loan from the Weld County Department of Health, noise levels were measured from plant/processing locations at two approved resource recovery locations located along St. Vrain Creek. Decibel readings were taken at 100 foot increments, commencing at ground zero where an El Jay cone crusher was operational as the principal noise source. Other background sources were operational as well, including several conveyors, screeners, and moving heavy equipment (both front end loaders and scrapers). • Varra Companies, Inc. Weld County USR 41 Western Sugar Reclamation Land Development Project November 2010 Initial readings varied by 10.0± db. Average readings radiating from the • principal source, beginning at ground zero, are as follows: Ground 0: 80± db @ 100.0± feet 70+ db * @ 200.0± feet 65± db ** @ 300.0± feet 60± db @ 400.0± feet 55± db * Note: A 10± db drop was consistently recorded at the first 100.0± feet from ground zero. ** Note: With each 100.0± feet of distance from the source, decibel readings dropped 5± db, beginning at a distance of 200.0± feet from the source. Average noise from a passing vehicles traveling on a paved segment of Weld County Road 13 at 55± mph, when measured 100± feet from the source, averaged 60± to 70± db, depending upon the size of the vehicle. The majority of area residences abut area roads and highways, therefore, the anticipated sound levels of any plant or processing activity is reasonably anticipated to be at or below 55± db, the background noise already present for area residences. • Again, to better assure tolerances are maintained, plant and processing equipment will not be closer than 400.0± feet from an adjacent residence not owned or controlled by the operator. Combined with the muting effect of the south and west hillsides and the inevitable product stockpiles surrounding the facilities, noise reaching area residences should approximate 55± db or lower, with a tolerance of 10± db. B. The operation of the USES shall comply with the air quality regulations promulgated by the Colorado Air Quality Control Commission. A Fugitive Dust Permit (10WE1751) will be secured from the Colorado Department of Health. All permits will be maintained and updated in accordance with Colorado Department of Health requirements. Additional permits will be secured as necessary to maintain compliance with planned processing activities as they come on—line. • Varra Companies, Inc. Weld County USR 42 Western Sugar Reclamation Land Development Project November 2010 C. The operation of the USES shall comply with the water quality regulations promulgated by the Colorado Water Quality Control Commission. A Stormwater Management Plan is in place for this operation under an established Universal Stormwater Management Plan utilized for all Varra Companies, Inc. project operations. An approved stormwater permit will be secured from the Colorado Department of Ilealth. Additional permits will be secured as necessary to maintain compliance with planned processing activities as they come on-line. D. The USES shall comply with the following lighting standards: 1. Sources of light, including light from high-temperature processes such as combustion or welding, shall be shielded so that light rays will not shine directly onto ADJACENT properties where such would cause a nuisance or interfere with the USE on the ADJACENT properties; and 2. Neither direct nor reflected light from any light source may create a traffic hazard to operators of motor vehicles on PUBLIC or private • STREETS and no colored lights may be used which may be confused with or construed as traffic control devices. Appropriate measures will be taken to comply with this section. For example: should a procedure such as welding be required on open ground, the service vehicle will be placed in an attempt to shield light emanating from such activity from nearby residences or local traffic. Where and when fixed lighting is necessary for the safety of personnel or visitors, operational lighting will to the extent possible and allowed by other regulating agencies (e.g., U.S. MSHA) be diffuse, deflected or otherwise directed away from area residences. Any planned processing or plant facilities will be located 400± feet or greater from any county road, or existing residence not owned or controlled by the applicant, minimizing the effects of facility lighting or noise on area residents or local traffic. All access into the property will intersect adjacent County roads perpendicularly. No colored lights will be used in a manner or proximity to County roads so as to be construed as a traffic control device. • Varra Companies, Inc. Weld County USR 43 Western Sugar Reclamation Land Development Project November 2010 E. The USES shall not emit heat so as to raise the temperature of the air more than five degrees (5°) Fahrenheit at or beyond the LOT line. There are no known uses planned under this submittal which would affect temperatures at or beyond the lot line. F. Property shall be maintained in such a manner that grasses and weeds are not permitted to grow taller than twelve (12) inches. In no event shall the property owner allow the growth of NOXIOUS WEEDS. A complete and thorough weed management plan will be implemented, as detailed in OMLR Exhibit I/J - Soils and Vegetation Information. The plan at a minimum conforms with this policy. G. Any off-site and on-site improvements agreement shall be made in conformance with the County policy on collateral for improvements. (Weld • County Codification Ordinance 2000-1; Weld County Code Ordinance 2007-1) Acknowledged. Sec. 23-2-260. Application Requirements. A. The purpose of the application is to give the petitioner an opportunity to demonstrate through written and graphic information how the proposal complies with the standards of this Chapter. The following supporting documents shall be submitted as a part of the application except for those items determined by the Director of Planning Services, in writing, or the Board of County Commissioners, on the record, to be unnecessary to a decision on the application: 1. A statement which explains that the proposal is consistent with Chapter 22 of this Code and any other applicable code provision or ordinance in effect. • Varra Companies, Inc. Weld County USR 44 Western Sugar Reclamation Land Development Project November 2010 The project conforms with Section 22-5-80 of Weld County's • Comprehensive Plan: Commercial and Mineral Resource Deposits Goals and Policies. Expansion of human habitat and related pressures on area infrastructure is already evident near this location. The City of Greeley borders the project location to the west and north. Industrial expansion is underway with site preparation for a new Leprino Cheese Plant and other industrial development to the West. While residential homes are bounded by significant open space from their A-Agricultural standing, residential densities appear to increase approximately one-half mile beyond the permit area to the south, and east into the city. The entire state of Colorado continues to be challenged by human migration to the state, and the resulting urban development is shaping State policies to enhance area infrastructure, including the enhancements of area roadways along and either side of Interstate 25 and Colorado Highway 85, for which this location is ideally situated to serve. With continued growth of human habitat and development, the products that serve the construction of this infrastructure comes from the ground. The aggregate resource must be recovered before it is overtaken by ever • expanding urban development, or it is lost. Now is the time and this is the geologically determined and economically feasible location from which the proposed extraction activity must occur. The extraction of aggregate resource is in fact resource conservation, and tends to lessen the future density of subsequent urban development resulting from the inevitable expansion of human habitat, supporting uses, facilities and infrastructure. It is in fact this existing and ever expanding urbanization of agricultural land that constitutes the greatest demand for this nonrenewable resource. Section 22-5-80 of Weld County's Code of Regulations is consistent with Colorado law, both of which require that this resource must be recovered prior to other development which would otherwise impede access to it. The subsequent development of a diverse multiple land use potential at this location, when complemented with sound environmental parameters, as advanced under this proposal and the attending OMLR permit exhibits, is in keeping with the spirit and intent of the policies and goals of Weld County. Approval of the application will allow the resource to be accessed and utilized in a reasonable and orderly manner as required under both Colorado law and the Weld County Code of Regulations. Varra Companies, Inc. Weld County USR 45 Western Sugar Reclamation Land Development Project November 2010 • 2. A statement which explains that the proposal is consistent with the intent of the district in which the USE is located. Under Title 34, the State of Colorado and Weld County require the removal of a valuable mineral deposit from those lands prior to development. The extraction of a mineral deposit is an allowable use within the Weld County Industrial 1-3 District; which applies to the entire lands considered under this application. Resource recovery simply cannot occur over lands developed with houses and other structures. By this submittal, the owner proposes to reclaim formerly blighted and neglected lands through extracting the underlying aggregate and reclaiming the resulting basins for water storage. All previously affected lands reaffected by planned activities and remaining above the anticipated static water level of the resulting reservoirs will be returned to a beneficial and stabilizing cover of predominantly native vegetation; except where existing access roads, structures or other reasonable obstacles • prevent it. The extraction is necessary to attain both the resource and end use objectives. Both extraction and the resulting basins are fully compatible with the surrounding lands. The planned activities over the formerly blighted lands will return them to a beneficial use, resulting in improved visual and fiscal enhancement to both the principle and surrounding land owners. 3. A statement which explains that the USES which would be permitted will be compatible with the existing surrounding land USES. The planned activities complement the surrounding City of Greeley Industrial uses to the west and north, including existing mining operations to the north and east. The location is flanked on the east and south by properties in the A-Agriculture Zone. Southeast of planned extraction homes lie slightly farther away from operational activity than they are for existing permitted extraction activity to their immediate north. South of the planned extraction homes line 16`1 Street more than 400 feet from Varra Companies, Inc. Weld County USR 46 Western Sugar Reclamation Land Development Project November 2010 planned activity. Noise emanating from an 80 decibel source (e.g., a cone • crusher) would be background residential level, or 55 decibels by the time it reaches 400 feet from the source. For the nearest residence to the southeast, extraction would not reach within four hundred feet until near the end of extraction operations, and again, would be slightly further away than activities at an existing operation to the immediate north of this residence. The residence is heavily buffered by a dense line of trees and shrubs between the permit area and the structure. With the exception of this single residence, all other sources are completely out of reach of any potential industrial noise levels, which operations are not anticipated to exceed. Each existing residence within the designated A-Agriculture zone is surrounded by trees and open space, further separating their residence from operational effects within the adjacent 1-3 zone. City of Greeley Industrial I-M (medium intensity) lands lie to the north and west of the permit boundary. These lands are either vacant, or • bounded by land disturbances such as settling basins, waste piles, or industrial buildings and support facilities or equipments. Other existing mining operations flank the permit boundary to the north and east. Planned activities within the permit boundary will not interfere with any of the surrounding Industrial lands or their current activities. Agricultural stock ponds, land leveling, use of equipment to manipulate land for crops, and other agricultural based activities are not uncommon in agricultural locations. As shown on the included Colorado Division of Reclamation Mining and Safety (CDRMS), Office of Mined Land Reclamation (OMLR) Exhibit C-2: Extraction Plan Map, the greater concentration of plant and processing activity, parking, machinery and equipment storage and stockpiling of materials is located in a manner that is removed from area residences and muted by area trees, open space and hillsides in the form of the flood plain escarpment. The location is approached internally and away from high density residential areas and roads. 4. A statement which explains that the USES which would be permitted will be compatible with the future DEVELOPMENT of the Varra Companies, Inc. Weld County USR 47 Western Sugar Reclamation Land Development Project November 2010 surrounding area as permitted by the existing zone and with future • DEVELOPMENT as projected by Chapter 22 of this Code and any other applicable code provision or ordinances in effect, or the adopted MASTER PLANS of affected municipalities. The project conforms with Section 22-5-80 of Weld County's Comprehensive Plan: Commercial and Mineral Resource Deposits Goals and Policies. Expansion of human habitat and related pressures on area infrastructure is already evident near this location. The extraction of aggregate resource is in fact resource conservation, and tends to lessen the future density of subsequent urban development resulting from the inevitable expansion of human habitat, supporting uses, facilities and infrastructure. It is in fact this existing and ever expanding urbanization of agricultural land that constitutes the greatest demand for this nonrenewable resource. Section 22-5-80 of Weld County's Code of Regulations is consistent with Colorado law, both of which require that this resource must be recovered • prior to other development which would otherwise impede access to it. The subsequent development of a diverse multiple land use potential at this location, when complemented with sound environmental parameters, as advanced under this proposal and the attending OMLR permit exhibits, is in keeping with the spirit and intent of the policies and goals of Weld County. Approval of the application will allow the resource to be accessed and utilized in a reasonable and orderly manner as required under both Colorado law and the Weld County Code of Regulations. The proposal complements the surrounding Industrial and Agricultural Districts. Resource recovery simply cannot occur over lands developed with houses and other structures. Where extraction occurs, the formerly blighted landscape will be replaced with water resources. Unlike other urban uses that intrude upon the agricultural districts, extraction is a transitional use, that leaves the final land in a configuration that prevents high density urban development, common to residential subdivision for example. The resulting basins create visual and functional amenities that harmonize the scale, function, and vistas of surrounding agricultural lands and • habitats. While residential development fragments wildlife habitat with Varra Companies, Inc. Weld County USR 48 Western Sugar Reclamation Land Development Project November 2010 increasingly larger building footprints for dwellings along with • incompatible landscapes and fence-works; the results following extraction typically do not result in such permanent diminished landscapes, habitats or densities. The reclamation of extracted lands in fact often incorporate or introduce concepts often lacking in other developmental impacts. The more open design elements include the creation of edge effect resulting from the reintroduction of a more native landscape with enhanced aquatic margins that better complement and aid wildlife and scenic values. Overall, final reclamation of the extracted lands create features that better complement and lend themselves to the visual enjoyment of the surrounding community. The Vicinity Map shows those properties currently under permitted extraction, or otherwise owned or leased by companies that will eventually open those lands to extraction. The Future Compatibility: The resulting reservoirs foreseen under the reclamation plan will result in lower density development toward the Cache La Poudre River watershed. Agricultural conversion to other extraction and mixed industrial, commercial and residential uses are already evident as shown on the • Vicinity Map. The water from the reservoirs can be made available for either urban or agricultural uses, but the basins alone are essential to providing a means to store and manage available waters. Any subsequent lower density development which may follow will still require necessary approvals from Weld County Building Department prior to the construction of any permanent structures, and from Weld County Planning, prior to the utilization of the parcels for any subsequent light residential, commercial or industrial uses beyond those already indicated under this submittal, and specifically indicated on OMLR Exhibit C-2: Extraction Plan Map. 5. A statement which explains that the application complies with Article V of this Chapter if the proposal is located within any Overlay District Area identified by maps officially adopted by the COUNTY. The location is outside of any known geologic hazard. The location is within the Weld County Airport `Influence Zone.' The project does lie within the floodplain and a portion of the defined floodway of the Cache La Poudre River. Operational effects should not adversely impact any of the • designated overlays, floodway or floodplain. Varra Companies, Inc.

The location as it is extracted will by its nature diminish any potential for fire or flood to surrounding lands. The localized access surrounding the basins, and the extraction itself resulting in basins below original ground will serve to cause direct precipitation to drain internally or otherwise serve to route or divert external overland flows to existing waterways, and in general serve as a firebreak to surrounding lands. • Varna Companies, Inc.

Any signage used by the operation for purposes of on-site MSHA, or related operational signage will conform to all specifications set forth in Chapter 23, Article IV, Division 2 of the Weld County Code of Regulations, including all setback, height and size specifications where applicable. C. A detailed description of the proposed operation and USE shall be supplied. Details for the following items, when applicable, are required: 1. Type of USE for which the application is being made. The application requests approval of an allowed use for the extraction of a valuable mineral deposit located within the existing Industrial I-3 land to allow for the conservation of the underlying aggregate deposit. Reclamation will result in water storage basins over the majority of the location. Revegetation will occur over all reaffected lands remaining above the anticipated static water level of extracted basins; or where not otherwise occupied by permanent roadways, structures or other uses; and will involve the application of the OMLR approved seed mixture detailed under OMLR Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture. The seed mixture will result in a stabilizing cover of predominantly native grasses over the affected lands. The emergent species of grasses vary in height, form, function, and color, and are highly adaptable to the new soils. Varra Companies, Inc. Weld County USR 58 Western Sugar Reclamation Land Development Project November 2010 • 2. Proximity of the proposed USE to residential STRUCTURES. Please refer to the Vicinity Map and OMLR Exhibit C-2: Extraction Plan Map where the proximity of existing residential structures are identified and shown to scale on an aerial photograph relative to the project boundary and planned extraction limits. No residential structure not owned or controlled by the applicant lies within 125.0 feet of the limits of extraction activity. Southeast of planned extraction homes lie slightly farther away from operational activity than they are for existing permitted extraction activity to their immediate north. South of the planned extraction homes line 16"' Street more than 400 feet from planned activity. Noise emanating from an 80 decibel source (e.g., a cone crusher) would be background residential level, or 55 decibels by the time it reaches 400 feet from the source. For the nearest residence to the southeast, extraction would not reach within four hundred feet until near the end of extraction operations, and • again, would be slightly further away than activities at an existing operation to the immediate north of this residence. The residence is heavily buffered by a dense line of trees and shrubs between the permit area and the structure. With the exception of this single residence, all other sources are completely out of reach of any potential industrial noise levels, which operations are not anticipated to exceed. Each existing residence within the designated A-Agriculture zone is surrounded by trees and open space, further separating their residence from operational effects within the adjacent 1-3 zone. 3. The number of shifts to be worked and the maximum number of employees. Consistent with the adjacent Durham Project; an average of 9± employees (6-12± at any one time) will work commonly in 8 to 12 hour shifts, except for those government jobs that require night time work, which may require up to three shifts over a 24 hour period. Other users include Varra Companies, Inc. Weld County USR 59 Western Sugar Reclamation Land Development Project November 2010 approximately (Range 20 - 200±) commercial and private haulers per day, • including an occasional visitor or inspector. Commonly, operations will occur six (6) days a week, Monday through Saturday, however, occasionally, contracts or other project obligations may from time to time require a full seven day work week, including Sunday. Flexibility of both hours and days is a necessary aspect of the nature of maintaining and building Weld County's infrastructure and agricultural, residential, commercial and industrial communities, all of which place variable and unpredictable demands for earth derived construction n1,lt�'ri.ils. twenty- lour hours a clay. seven days a week (2 I/7). \ more precise estimate and breakdown is not realistic. and any numbers represented are estimates that will vary I)y circumstances and market conditions prevalent at the time. 4. The maximum number of users, patrons, members, buyers or other visitors that the use by special review facility is designed to accommodate at any one (1) time. • Please refer to Part 3, above. 5. Types and maximum numbers of animals to be concentrated on the site at any one (1) time. No animal concentration applies to this operation, however, historic uses, including past agricultural uses for cattle, horses, or other livestock, are not intended to be surrendered by this transitional use. 6. Types and numbers of operating and processing equipment to be utilized. Equipment may include, but is not limited to: • One or more cone crushers and attending screens, conveyors, and • supporting electrical equipment and trailers; Varra Companies, Inc. Weld County USR 60 Western Sugar Reclamation Land Development Project November 2010 • Portable concrete and asphalt plants; • • Recycling processing equipment; • Grader, scrapers, bulldozers, front—end loaders, haul trucks of various sizes and weights, and conveyor systems; • Scalehouse and scale; • Supporting facilities and trailers, including portable storage sheds and trailers. 7. Type, number and USES of the proposed STRUCTURES to be erected. All equipment and supporting structures planned for the operation at this time are temporary (e.g., scalehouse; aggregate, concrete and asphalt plant/processing and related equipment; control towers and power trailers, etc.) all of which are portable and will be transported to the designated plant and stockpile area identified in OMLR Exhibit C-2: Extraction Plan Map. Any permanent non-portable structures will receive any necessary building permits from the Weld County Building Department prior to construction. • 8. Type, size, weight and frequency of vehicular traffic and access routes that will be utilized. Trucks may vary from pick-up size to small trailers for the general public, to 15 ton tandem or 25 ton semi commercial haulers with an anticipated production departing the site of up to 4,000 tons per day. Generally, vehicle weights will fall within 85,000± pounds or less. Routes into and away from the property will access through the adjacent industrial lands to the west and Ash Avenue. All existing access from Ash Avenue will be used to facilitate access for authorized personnel, service vehicles, vendors, or occasional use. The on-site access for haul roads, heavy equipment, conveyors, and general traffic flanks the respective basins as shown on OMLR Exhibit C-2: Extraction Plan Map. 9. Domestic sewage facilities. Varra Companies, Inc. Weld County USR 61 Western Sugar Reclamation Land Development Project November 2010 While there are not existing sanitary facilities for the planned activities, prior to on-set of operations, the operator will provide two (2) commercially available port-o-lets near the entrance, accessible to both employees and visitors. 10. Size of stockpile, storage or waste areas to be utilized. Please refer to OMLR Exhibit C-2: Extraction Plan Map for the location of the Plant and Stockpile Areas designated for the operations. I Ieight of deposit stockpiles will vary but average up to 30± feet. Soil stockpile height will also vary up to 30± feet when not comprised as part of the perimeter berm. 11. Method and time schedule of removal or disposal of debris, JUNK and other wastes associated with the proposed USE. • Debris or other unwanted material will not accumulate over the location for purposes of sanitation, safety, and general courtesy to our neighbors. All unwanted materials will be removed within 30 days of deposition to an appropriate land fill or other suitable location. Recyclable material will either be stockpiled and recycled on-site or transported to another permitted recycling location; or taken to an authorized land fill or other suitable location. Generally, all waste or recyclable materials will be centralized at the designated plant site location identified on OMLR Exhibit C-2: Extraction Plan Map; and will utilize appropriate containers, pallets, or be of a nature inert to the area environment and stable in its present condition of and method storage if stockpiled in a manner open to the elements. 12. A time table showing the periods of time required for the construction of the operation. • Varra Companies, Inc. Weld County USR 62 Western Sugar Reclamation Land Development Project November 2010 Please refer to OMLR Exhibit D - Extraction Plan and Exhibit C-2: • Extraction Map. While any Tract may commence at start-up, the anticipated sequence will occur as identified, below. Essentially, extraction will commence with Tract B, followed by Tracts C, D, and A. All tracts may be extracted concurrently * The total 102.87± acres permitted under the Weld County USR, and the Colorado Office of Mined Land Reclamation [OMLR] permit will have a total life of approximately twenty-five (25±) years, ending sometime in the year 2035, depending upon market demand. Approved reclamation for all open areas of extraction and disturbed land will be secured by an appropriate financial warranty as determined by the OMLR, and adjusted to cover circumstances as they occur over the life of the operation. Simultaneous extraction will tend to accelerate the overall completion of extraction activities and final reclamation of the location, to the extent that it occurs. * depending upon market demand. • 13. Proposed LANDSCAPE plans. Revegetation will occur over all reaffected lands remaining above the anticipated static water level of extracted basins; or where not otherwise occupied by permanent roadways, structures or other uses; and will involve the application of the OMLR approved seed mixture detailed under OMLR Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture. The seed mixture will result in a stabilizing cover of predominantly native grasses over the affected lands. The emergent species of grasses vary in height, form, function, and color, and are highly adaptable to the new soils. 14. Reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. Reclamation is concurrent with continuous resource recovery operations. • Extraction activities will remove aggregate to a mean depth of 40.0± feet Varra Companies, Inc. Weld County USR 63 Western Sugar Reclamation Land Development Project November 2010 from the surface. Anomalous depths from 22.0± to 86.0± feet may occur. • While extracted slopes may be temporarily 1.25H:1V, all final basin (reservoir) slopes will be established concurrently with extraction and will conform to OMLR Rule 3.1.5(7), or flatter. The general direction of extraction activities over the diverse Tracts is shown on OMLR Exhibit C-2 - Extraction Map. Extraction will not occur within 125± feet of any residential structure. Extraction will occur to within 10.0± feet of the permit boundary, easements, right-of-ways, and non-residential structures; except that extraction activities will be limited to within 25.0± feet of well heads and facilities. Those same wellheads will be backfilled to create a 100 foot radius around the well head for future oil and gas activities at that well head. Fill will be placed concurrently with extraction around the well head and related facilities, to the extent practical. At all times, safety will take precedent. While the on-set of reclamation is concurrent with extraction, the completion of reclamation may lag up to five (5.0±) years behind the onset of reclamation activities. Complete extraction of the permit area is expected to take approximately 20 years, depending upon market • conditions, with an additional 5 years following completion of all extraction activities for ultimate completion of concurrent reclamation activities, placing the completion of all activities near 2035, depending upon market demand. Because the permit area may be fully affected, phasing does not adequately describe the extraction and reclamation potential of the permit area. Tracts are used, since each Tract can be accessed concurrently with the other, and per OMLR Exhibit L - Reclamation Costs, accelerated extraction only serves to decrease the overall reclamation liability and accelerate final reclamation and site stabilization of the property as a whole. Therefore, any method that accelerates the above timetable, including concurrent reclamation ongoing within each tract, will be utilized, based upon market conditions and the capacities of the operator. As indicated in OMLR Exhibit E - Reclamation Plan: As extraction progresses over planned areas in Tracts A, B, C and D; the resulting 1.25H:1V slopes created during extraction will be concurrently modified by pushing the resulting pit bottom with a dozer until the resulting basin slopes conform with OLMR Rule 3.1.5(7). Lands above the anticipated Varra Companies, Inc. Weld County USR 64 Western Sugar Reclamation Land Development Project November 2010 static water level of the basins and within 10.0± feet below the • anticipated final water level of the basins will be graded to 311:1V, or flatter. Lands below 10.0± feet from the anticipated final water level of the basins may approach 2H:1V. Naturally occurring slopes may exceed 2H:1V where not otherwise affected by extraction activities and will not be altered as part of reclamation unless necessary to facilitate the reclamation of affected lands. A Backfill Notice is included with this application as an Addendum at the back of OMLR Exhibit E - Reclamation Plan, to facilitate the fill of portions of the extracted lands for final end-use potentials beyond reservoir storage, which may include residential, commercial or industrial structures or uses otherwise approved, now or in the future, by Weld County, Colorado. The extent and nature of the reservoir represents the maximum build-out respective of optimal extraction of commercial product and resulting final slopes. All affected lands above the anticipated high water mark of the reservoirs will be capped with a minimum of six (6.0±) inches of soil, as supported by OMLR Exhibit I & J - Soils and Vegetation Information. Timing and use of • soil is detailed further under OMLR Exhibit I & J — Soils and Vegetation Information and Exhibit L - Reclamation Costs. Where compacted lands exist, and are to be revegetated, those locations will be ripped prior to re-soil application. There are no known areas of compaction at the time of this application which would require such activity; and ripping remains a contingency of the application. The final land configuration results in four reservoir basins totaling 62.81± surface acres (refer to OMLR Exhibit F: Reclamation Map). The balance of unoccupied affected lands above the anticipated final water level will be stabilized where necessary utilizing the approved OMLR seed mixture, as detailed under OMLR Exhibit L - Table L-1: Primary/Preferred Re- vegetation Seed Mixture. Lands not otherwise occupied will be later developed to the highest possible end-use, and will likely comprise a mixed use which may include other agricultural uses as well as light residential, commercial or industrial uses. All reaffected lands remaining above the anticipated final water level of the ponds, and not otherwise occupied by existing or planned mixed uses, will be re-vegetated with the approved seed mixture(s) for general • agriculture. To aid in the establishment and survival of the preferred Varra Companies, Inc. Weld County USR 65 Western Sugar Reclamation Land Development Project November 2010 species, a wheatxwheatgrass sterile hybrid will be combined with either applied mixture as a substitute for the use of mulch. The formerly irrigated pasture was likely comprised predominantly of introduced species, and by neglect deteriorated to a near monoculture of kochia (Kochia scoparia). Since the blighted land is being replaced with predominantly native grasses, the target for release over the revegetated lands is based upon the establishment of a stabilizing cover whose foliar umbrella equals or exceeds 25 percent of the total area of the ground as measured three inches above the native soil on a square meter basis for typical areas of reclaimed cover achieved within five years subsequent to the completion of all extraction activities. Mixed use(s), other than industrial will occur and may include, but are not limited to: the retention of existing structures as desired for continued industrial - commercial use (as validated by any co-related and required Weld County Building Permits); the creation of unforeseen future structures, and for the use and development of on-site water resources. Since the area of surrounding lands is a mix of these uses, the site end use will retain these potentials. • The rate of reclamation activity, including grading, soiling and revegetation will follow concurrently with extraction and the respective timetables identified for extraction under OMLR Exhibit D — Mining Plan. All timetables are contingent upon market conditions, therefore, a probable range of time is indicated. With extraction activities anticipated to take up to 20 years to complete, reclamation will add an approximately five years to this estimate, bringing the anticipated life of the mine to 25± years, or the year 2035, depending upon market demand. 15. A statement delineating the need for the proposed USE. With continued growth of human habitat, infrastructure, energy, commerce and related development, combined with existing maintenance needs in both urban and agricultural locations, the products that serve these needs comes from non-renewable aggregate resources found in unique and limited geological locations. This aggregate resource must be recovered in advance of other development or it is lost. Now is the time and this is the geologically derived and economically feasible location available for • such use. Varra Companies, Inc. Weld County USR 66 Western Sugar Reclamation Land Development Project November 2010 • The initial site selection is influenced by the logistics of diverse market, economic and geological considerations. For example, the site must be located in the target market which is limited both by the location of recoverable aggregate, the offer of lands with marketable aggregate within them, and a proper demographic that allows for the product to reach markets based upon supply, demand, transportation distances and other economic considerations. Sociology, geography, and competition with other suppliers also influence these decisions. A source located in the foothills is not only highly difficult to obtain due to social resistance, it cannot compete for customers further out in the Great Plains where competitors with closer sources simply can out compete with lower bids due to lower transportation and production costs for customers nearer to them. Aggregate is a geologic deposit and it simply must be taken where it lies closest to the market need, as such lands are made available through the real estate market for purchase. Additionally, the aggregate deposit must be viable for recovery. In other words, to justify the costs of recovery, the deposit must be large enough in volume by depth and extent to justify • the effort. The deposit must also offer the quality and diversity of rock product that the local market demands. Once a site with suitable aggregate quality, volume and market potential is determined, the selection of a site is still influence by other factors that affect competition and viability of the location. Simply put, the site must be affordable, the deposit must be accessible, and the sociology (capacity to obtain permits, labor, equipment, etc.) suitable to allow for the extraction of the deposit to actually occur. These considerations not only determine how viable the resource is for recovery, it has a direct bearing on how expensive a highway segment, residential development, foundation or sidewalk will be. An abundance of aggregate supply in the near proximity of human development activity will make the development of the infrastructure of that community more affordable due to the market forces of supply and demand than it will be where the same material must be transported longer distances from more remote deposits. The more remote the source is from the target market, the greater the impact on transportation systems, fuel demand, as well as wear and replacement of vehicles and • equipment. Varra Companies, Inc. Weld County USR 67 Western Sugar Reclamation Land Development Project November 2010 • For these reasons, area impacts from a source increase radially and may be felt by communities that do not necessarily receive product but simply act as corridors for its movement to the demand locations. It is for this reason that local deposits serving a more local market minimize both regional and cumulative impacts to area communities while best benefiting the economic interests of the local community nearest the source. Near or far, a source is always involved, and it is the demand that creates the need for the source. Another consideration is that extraction is unlike most other urban or rural activity. Extraction of aggregate resource is unique in that it is a transitional use of the land. Extraction is market driven by human population and demand in both rural and urban markets. The product must be extracted before any development can occur over the affected land, both legally, and practically. The demands on post extraction development are that the land be developed to the highest potential end use or uses. Planning for reclamation or restoration of the post extracted land often • incorporates multiple end-uses involving a mixture of potentials for water resources, agricultural, residential, commercial or industrial development. The end-use reclamation must anticipate changes to the surrounding community 15 to 30 years between when a typical resource recovery operation begins and completes extraction and reclamation activities. The flexibility of multiple end-use planning helps capture the best complement of uses and values for the post extraction morphology and demographics. The demographics of a community are fluid, dynamic, yet commonly evidenced by increased human population and pressure on natural systems. In other words, the rural and native landscapes are transformed to the urban. Resource recovery operations typically exist at the cusp of this transformation. The resulting basins and altered but native alluvial landscapes serve to counter increased densities from the urban process, later viewed from higher ground nearby, often on a softwood deck pillared atop a bluegrass lawn. Another unique consideration in the recovery of aggregate is that it often occurs in alluvial areas where wetlands exist. Unlike the placement of a house, roadway, housing development, industrial or commercial sites and • development, and utility or oil and gas facilities; aggregate must be Varra Companies, Inc. Weld County USR 68 Western Sugar Reclamation Land Development Project November 2010 removed where it lies. The only choice once a deposit is determined to • be viable is how to remove it respective of unremedial obstacles (obstacles that cannot be cost effectively removed, repaired or replaced without exceeding the value of the aggregate deposit underlying them). Wetlands are considered by VCI as unremedial obstacles and to be avoided unless they can be mitigated under an approved plan, such as an U.S. Army Corps of Engineers Nationwide or Individual Permit. Even then, only when the wetland (often in part but not the whole) poses an obstacle that threatens the economic vitality of the operations, the end- use potentials hoped for, and can otherwise be successfully mitigated through the potentials of reclamation methods and practices will the challenge of extracting through a wetland be considered. Under this submittal, there are no planned impacts to wetlands. Neither can the act of removing the deposit and avoiding obstacles remain the first and last consideration. All lands affected by extraction must be reclaimed or restored to an acceptable end use or range of uses. Post extraction end use is ultimately determined by the same market factors and land potentials that influence all human influences on the land; • working imaginatively with the character of the affected lands as characterized by the extraction activities. Extracted lands simply are not allowed, by law or practicality, to be simply abandoned in place subsequent to extraction activities. For this reason, once a site has been acquired for extraction, the least viable sites have already been considered and rejected; making the source site the preferred site because it meets the requirements of the local market (i.e., The site is near or within a viable local market with competitive elements of transportation, labor, equipment and other logistics - has a viable deposit that can justify the cost of acquisition, permitting, and establishment of infrastructure for extraction - and offers a good potential for post recovery development.). More simply stated, the aggregate resource must be conserved and recovered prior to the development over such lands. Aggregate resources must be extracted where they occur, and most often benefit the communities and urban infrastructures most local to the planned operations. • Varra Companies, Inc.

A detailed description of the method of operation. Such description shall include: 1. The types and numbers of operation and processing equipment to be employed. • Varra Companies, Inc. Weld County USR 76 Western Sugar Reclamation Land Development Project November 2010 • The operation involves the surface extraction of aggregate. Surface soil is removed from the underlying deposit. Soil in excess of that required for reclamation is considered a resource. Extraction if typically over the shoulder removal of the deposit utilizing (but not limited to) bulldozers, scrapers, front end loaders, and excavators. Extracted materials are typically transported by haul truck or conveyor to a designated plant area for processing. Operations require the flexibility of bringing to the designated plant site location (Tract A, as shown on OMLR Exhibit C-2: Extraction Plan Map) portable and temporary equipment, including a scale, scalehouse, wet processing plant, dry processing plant, portable concrete and/or asphalt plants; and/or recycling operations and related processing equipment. All equipment and plants are temporary and portable. Any permanent structures to be constructed on site and requiring and will apply for and obtain all required building permits through the Weld County Building Department prior to construction of regulated facilities. • 2. The number of shifts to be worked and the maximum number of employees. Consistent with the adjacent Durham Project; an average of 9± employees (6-12± at any one time) will work commonly in 8 to 12 hour shifts, except for those government jobs that require night time work, which may require up to three shifts over a 24 hour period. Other users include approximately (Range 20 - 200±) commercial and private haulers per day, including an occasional visitor or inspector. Commonly, operations will occur six (6) days a week, Monday through Saturday, however, occasionally, contracts or other project obligations may from time to time require a full seven day work week, including Sunday. Flexibility of both hours and days is a necessary aspect of the nature of maintaining and building Weld County's infrastructure and agricultural, residential, commercial and industrial communities, all of which place variable and unpredictable demands for earth derived construction ma tv rials.

Weld County USR 77 Western Sugar Reclamation Land Development Project November 2010 • 3. Whether the operation will involve a wet or dry pit. The operator requires discharge of groundwater to gain access to the necessary product in the most economically viable means possible. The pit will be maintained dry until such a time as extraction and basin slope reclamation and resoiling are completed for each Tract of the project. Extraction activities will continue to remove aggregate from approximately 15-25± feet along the southwest, to a mean depth of 35- 40.0± feet at center, with a potential total depth to 70-80± feet along to the Cache La Poudre River. Since anomalous depths greater than 40± feet may occur, any extraction deeper than 40± feet in depth, may be extracted either dry, or wet. If extracted wet, a dredge may be utilized for the removal. 4. COUNTY roads and bridges to be utilized. • None. 5. The size of the area and stages to be worked at any one time. Please refer to Parts 6, 7, and 8, below. The stages and areas to be worked are further identified in the OMLR Exhibit D - Extraction Plan and Exhibit C-2: Extraction Map. While all tracts can be worked simultaneously, the rate, direction, and order of extraction will be determined by the strategies outlined in the extraction and reclamation plan exhibits, and by prevailing market conditions. 6. A timetable giving the periods of time which will be required for the various stages of the operation. • Varra Companies, Inc. Weld County USR 78 Western Sugar Reclamation Land Development Project November 2010 Please refer to OMLR Exhibit D - Extraction Plan and Exhibit C-2: Extraction Map. While any Tract may commence at start-up, the anticipated sequence will occur as identified, below. Essentially, extraction will commence with Tract B, followed by Tracts C, D, and A. All tracts may be extracted concurrently * The total 102.87± acres permitted under the Weld County USR, and the Colorado Office of Mined Land Reclamation [OMLR] permit will have a total life of approximately twenty-five (25±) years, ending sometime in the year 2035, depending upon market demand. Approved reclamation for all open areas of extraction and disturbed land will be secured by an appropriate financial warranty as determined by the OMLR, and adjusted to cover circumstances as they occur over the life of the operation. Simultaneous extraction will tend to accelerate the overall completion of extraction activities and final reclamation of the location, to the extent that it occurs. * depending upon market demand. • 7. The depth and thickness of the mineral deposit to be mined and the thickness of overburden to be removed. Please refer to OMLR Exhibit D - Extraction Plan and Exhibit C-2: Extraction Map. Extraction activities will remove aggregate to a mean depth of 40.0± feet from the surface. Anomalous depths from 22.0± to 86.0± feet may occur. 8. The proposed use of reclaimed lands and an explanation of the reclamation process. As indicated in OMLR Exhibit E — Reclamation Plan: As extraction progresses over planned areas in Tracts A, B, C and D; the resulting 1.25H:1V slopes created during extraction will be concurrently modified by pushing the resulting pit bottom with a dozer until the resulting basin slopes conform with OLMR Rule 3.1 .5(7). Lands above the anticipated • static water level of the basins and within 10.0± feet below the Varra Companies, Inc. Weld County USR 79 Western Sugar Reclamation Land Development Project November 2010 anticipated final water level of the basins will be graded to 3H:1V, or • flatter. Lands below 10.0± feet from the anticipated final water level of the basins may approach 2Ii:1V. Naturally occurring slopes may exceed 2II:1V where not otherwise affected by extraction activities and will not be altered as part of reclamation unless necessary to facilitate the reclamation of affected lands. A Backfill Notice is included with this application as an Addendum at the back of OMLR Exhibit E - Reclamation Plan, to facilitate the fill of portions of the extracted lands for final end-use potentials beyond reservoir storage, which may include residential, commercial or industrial structures or uses otherwise approved, now or in the future, by Weld County, Colorado. The extent and nature of the reservoir represents the maximum build-out respective of optimal extraction of commercial product and resulting final slopes. All affected lands above the anticipated high water mark of the reservoirs will be capped with a minimum of six (6.0±) inches of soil, as supported by OMLR Exhibit I & J — Soils and Vegetation Information. Timing and use of soil is detailed further under OMLR Exhibit I & J - Soils and Vegetation • Information and Exhibit L - Reclamation Costs. Where compacted lands exist, and are to be revegetated, those locations will be ripped prior to re-soil application. There are no known areas of compaction at the time of this application which would require such activity; and ripping remains a contingency of the application. The final land configuration results in four reservoir basins totaling 62.81± surface acres (refer to OMLR Exhibit F: Reclamation Map). The balance of unoccupied affected lands above the anticipated final water level will be stabilized where necessary utilizing the approved OMLR seed mixture, as detailed under OMLR Exhibit L - Table L-1: Primary/Preferred Re- vegetation Seed Mixture. Lands not otherwise occupied will be later developed to the highest possible end-use, and will likely comprise a mixed use which may include other agricultural uses as well as light residential, commercial or industrial uses. All affected lands remaining above the anticipated final water level of the ponds, and not otherwise occupied by existing or planned mixed uses, will be re-vegetated with the approved seed mixture(s) for general agriculture. To aid in the establishment and survival of the preferred • species, a wheatxwheatgrass sterile hybrid will be combined with either Varra Companies, Inc. Weld County USR 80 Western Sugar Reclamation Land Development Project November 2010 applied mixture as a substitute for the use of mulch. The formerly • irrigated pasture was likely comprised predominantly of introduced species, and by neglect deteriorated to a near monoculture of kochia (Kochia scoparia). Since the blighted land is being replaced with predominantly native grasses, the target for release over the revegetated lands is based upon the establishment of a stabilizing cover whose foliar umbrella equals or exceeds 25 percent of the total area of the ground as measured three inches above the native soil on a square meter basis for typical areas of reclaimed cover achieved within five years subsequent to the completion of all extraction activities. Mixed use(s), other than industrial will occur and may include, but are not limited to: the retention of existing structures as desired for continued industrial - commercial use (as validated by any co-related and required Weld County Building Permits); the creation of unforeseen future structures, and for the use and development of on-site water resources. Since the area of surrounding lands is a mix of these uses, the site end use will retain these potentials. The rate of reclamation activity, including grading, soiling and • revegetation will follow concurrently with extraction and the respective timetables identified for extraction under OMLR Exhibit D — Mining Plan. All timetables are contingent upon market conditions, therefore, a probable range of time is indicated. With extraction activities anticipated to take up to 20 years to complete, reclamation will add an approximately five years to this estimate, bringing the anticipated life of the mine to 25± years, or the year 2035, depending upon market demand. 9.

The applicant shall submit to the Department of Planning Services a copy of an agreement with the owner of any ditch located on or adjacent to the site, OR shall provide written evidence that an adequate attempt has been made to mitigate the concerns of the ditch owners. The agreement shall stipulate that ditch activities have adequately been incorporated into the design of the site. If such agreement cannot be reached, the applicant shall present • Varra Companies, Inc. Weld County USR 82 Western Sugar Reclamation Land Development Project November 2010 evidence that an adequate attempt to reach such agreement has • been made. There are no known ditches outside of the control of Varra Companies, Inc. within the permit area. 13. The application should address the following items: a. Water Consumption: 1) An analysis of the amount of water which will be required to be replaced for each phase of the mining operation and build out. The estimated water required for the build out development totals 118.94± acre-feet per year. This includes water for dust control, water lost in the product, concrete production, and evaporation losses from the potentially exposed ground water. This is the maximum water requirement projected for • the mine. Following extraction, if the extracted basins are lined as planned, the ultimate water demand will be zero. 2) The analysis should address the amount of water consumed in the mining and processing of the material, including dust suppression. Water consumed by operations is addressed in part 3 of OMLR Exhibit G: Water Information. Water consumed for processing is pending establishment of plant facilities. 3) The analysis should address the issue of water consumed for domestic purposes by onsite staff. Water consumed for domestic purposes will utilize water bottles or other containerized water transported to the site or Varra Companies, Inc. Weld County USR 83 Western Sugar Reclamation Land Development Project November 2010 otherwise supplied by the local water district and is, • therefore, not included in this water analysis. 4) The analysis should address the issue of evaporative losses consumed from exposed groundwater, including a discussion of the feasibility of lining. The annual evaporation as estimated by the National Weather Service in its "Evaporation Atlas for the Contiguous 48 United States" (Technical Report NWS 33) totals 42.12± inches per year. This is reduced by the effective precipitation and native vegetative credit. According to the State Engineer's guidelines, the effective precipitation is 70.0± percent of the total precipitation. The total precipitation reported for the Greeley station was 14.27± inches per year. The effective portion from November through March is 2.31± inches per year. The native vegetative credit is 22.79± inches from April through October. These two deductions from the total • evaporation is the net evaporation of 17.02± inches per year. Applying net evaporation to a potentially exposed area of 62.81± acres, results in an estimated potential net evaporation of 89.09± acre-feet per year. The reclamation plans are to line the pits. When the lining occurs, the evaporation losses would no longer directly deplete the stream system. Until lining is completed under the authority of the Colorado Division of Water Resources, Office of the State Engineer (OSE), Varra Companies, Inc. had sufficient water resources to augment for evaporative loss. Groundwater will not be exposed by extraction activities until it has received an approved Substitute Supply Plan from the OSE, a copy of which will be made available to the Weld County Department of Planning Services. b. Water Replacement Source: 1) A description of the surface and well water rights and its anticipated yield, when converted, to be used as • Varra Companies, Inc. Weld County USR 84 Western Sugar Reclamation Land Development Project November 2010 replacement for the water consumed in the mining • operation. Water will be supplied by two sources: shares of the Rural Ditch Company and water decreed in Case No. 01CW274. VCI owns four shares of Rural Ditch Company. The substitute water supply plan request shows that one and a half (1.5) shares of the Last Chance Ditch Company and four (4.0) shares of the Rural Ditch Company are necessary to replace the Western Sugar Reclamation Land Development Project potential stream depletion. The I Iayseed Ditch ownership was changed in Case NO. 90CW174. The change of four of the Rural Ditch Company shares has been requested in Case No. 03CW306. 2) Projections as to the timing of replacements to the river system from these sources. The replacement to the river system from these sources will be made directly during the historical irrigation season. The non-irrigation season replacements will be made from water stored in a lined facility. The stored water will accrue from excess credits available during the irrigation season and from junior appropriations. A substitute water supply plan that allows storage of the excess credit from four (4.0) Rural Ditch shares has been approved by the State Engineer for the Durham Project (Facility 117). Use of the lined facilities known as the Firestone Project (Facility 112) and Dakolios were decreed in Case No. 01CW274. Water will be supplied by two sources: shares of the Rural Ditch Company and water decreed in Case No. 01CW274. VCI owns four shares of Rural Ditch Company. From April through October, water use at the site will be replaced to the stream system using the historical consumptive use credits Varra Companies, Inc. Weld County USR 85 Western Sugar Reclamation Land Development Project November 2010 from any of the sources and/or from storage. Additional • information may be found in part 4 of OMLR Exhibit G: Water Information. 3) A description of methods proposed to monitor, prevent and mitigate against direct injury to users for wells in the vicinity of the gravel operation as a result of alterations in the groundwater regime occasioned by the mining operation or to said impacts. (Weld County Codification Ordinance 2000-1; Weld County Code Ordinance 2001- 1; Weld County Code Ordinance 2003-10) The State Engineer's procedure for permitting the gravel operation well includes notification of well owners located within 600 feet of the proposed gravel operation. These owners can either sign a waiver indicating their approval of the operation or request a hearing before the State Engineer. Based on the waivers or the evidence presented at the • hearing, the State Engineer will either approve the permit with appropriate terms and conditions or deny the well permit. The approved permit will contain the requirements that the state deems appropriate to protect against direct injury for users of wells in the vicinity of the gravel operation. Those requirements will be made available to Weld County. Sec. 23-4-270. Drawing Requirements. All applications shall be accompanied by the following maps which shall be delineated in drawing ink on Mylar or other drafting media approved by the Department of Planning Services in the following size: twenty-four (24) inches by thirty-six (36) inches.

The concurrent establishment of a perimeter berm of soil of varying width up to five (5.0±) feet in height will, at a minimum, flank significant portions of the perimeters of each tract of extracted and reclaimed land, thereby adding to the depth of the setback. While the berm width will vary, it will fit within the ten (10.0±) foot buffer between the permit boundary and any planned extraction, and if wider, will extend into the basin area conforming to 3I-1:1V minimum outslopes. • E. Insofar as practicable, all means of access to the property from any STREET shall be located and designated as to avoid the routing of vehicles to and from the property over STREETS that primarily serve residential DEVELOPMENT. Acknowledged. The location of the designated primary access road will tend to minimize the use of area residential roads. Ash Avenue as it flanks the west boundary of the project connects the several existing and potential industrial uses and zones between 8°i and 16`x' Streets where heavy haulers commonly utilize as a means to and from those uses and access to and from Colorado I lighway 85 to the west. While existing agricultural access are preserved as secondary access for senior personnel and the landowners/users, all visitors and laborers will utilize the primary access. Parking will be commonly limited to the plant and stockpile area identified on OMLR Exhibit C-2: Extraction Plan Map, except where internal operations are necessary to the extraction, transport, communication and maintenance of extraction activities and equipment, and for the necessary • access by authorized personnel or support services. Employee parking will be Varra Companies, Inc. Weld County USR 91 Western Sugar Reclamation Land Development Project November 2010 flexible to better accommodate internal operations as necessary respective of • the extraction, transport, communication and maintenance of extraction activities and equipment, and for the necessary access by authorized personnel or support services. Visitor parking will be directed to the scale house or otherwise restricted by signage. All Varra Company, Inc. personnel are encouraged to observe area speed limits in established company safety policy. Posted speed limits of 15 mph will be evident along the primary access road, or as otherwise determined in cooperation with U.S. MSIIA requirements. Minimum specification of access where they meet Weld County roads, as specified in Part 9, below, will be honored. F. All access roads from sand and gravel operations to PUBLIC highways, roads or STREETS, or to adjoining residential STRUCTURES, shall be paved or otherwise treated to minimize dust conditions on all parts of such access roads which are located within one-fourth (1) mile of the PUBLIC highway, road, STREET or adjoining residential STRUCTURE. • Internal haul roads will be kept damp through the use of water applied by a water truck during haul operations. A fugitive dust permit will be approved for the operation under permit I0WE1751 with the Colorado Department of health. Extracted material is commonly moist and as extraction advances below original ground, when combined with existing buffers, and other management practices, air borne materials will be fully minimized. Since the prevailing winds are generally from the west, and as the lands are situated below area residences, incidental wind related effects will tend to blow material east and away from the nearest residences along the southern flank of the location. G. Prior to starting excavation in certain specific instances, as first determined by individual investigation by the Board of County Commissioners, where excavations are considered hazardous or otherwise harmful to nearby residents or to their property, the Board of County Commissioners may require the excavations to be fenced or that some other action be taken on the part of an operator in order to minimize the hazardous situation. Chain link fencing to keep out young children, three-strand barb wire to keep out LIVESTOCK, acceleration/deceleration lanes to facilitate the safe/smooth flow of traffic, and • Varra Companies, Inc. Weld County USR 92 Western Sugar Reclamation Land Development Project November 2010 water augmentation to compensate for water losses caused by evaporation are • examples of actions which may be required by the Board. The property is surrounded by fencing south of the Cache La Poudre River, with steel gates securing all entrances. Repairs will be made as needed to downed fence prior to onset of extraction activities. All repairs will meet or exceed the nature of the existing fence, which varies according to the adjacent landowners. All gates are locked when personnel are absent from the location to better discourage unauthorized access H. Where topsoil is removed, sufficient arable soil shall be set aside, for respreading over the excavated area. Sufficient and suitable soil will be set in reserve for the reclamation and revegetation of reaffected lands remaining above the anticipated final water level of the extracted basins as detailed in OMLR Exhibit E — Reclamation Plan, Exhibit I/J - Soils and Vegetation Information. • I. Rock crushers and similar accessory facilities and equipment, but not including batching (concrete and asphalt) facilities may be allowed. However, the Planning Commission or Board of County Commissioners may set out additional conditions under which these operations may be permitted; and said conditions may vary by location due to abutting land USES. Concrete and asphalt batch plants shall meet the requirements of Section 23-3-40. Acknowledged. J. Insurance. The operator shall furnish evidence that he or she is insured to the extent of not less than one hundred thousand dollars ($100,000.00) against liability for any negligent act or omission by the operator from the operation or maintenance of the sand and gravel pit and the extraction and production of sand and gravel and all activities connected with or incidental thereto. • Varra Companies, Inc.

If the USE may result in injury to vested or conditional water rights, the applicant shall present a copy of a well permit to the Department of Planning Services prior to recording the Plat or at a time designated by the Board of County Commissioners, either supported by a plan of exchange or substitute supply approved by the State Engineer or a decreed plan for augmentation approved by the District Court for Water Division No. 1 which prevents injury to vested and conditional water rights. (Weld County Codification Ordinance 2000-1; Weld County Code Ordinance 2003-10) The applicant shall present a copy of the approved substitute supply plan and well permit to the Department of Planning Services prior to recording the Plat or otherwise, prior to exposing groundwater at the location, or as otherwise designated by the Board of County Commissioners. The information provided by • the applicant's water engineer in Sec. 23-4-260 (13) and The Water Supply Information Sheet as submitted to fulfill Sec. 30-28-133 (d), C.R.S., is consistent with information to be provided to the State Engineer as part of the applicant's assurance that operations will not result in an injury to vested and conditional water rights. Sec. 23-4-300. Reclamation Policies. A. Reclamation plans shall be reviewed to determine the compatibility of the proposed USE with surrounding land USES. Acknowledged. Please refer to Questionnaire — Parts 2 and 3. B. Following the completion of operations, the land shall be left in a safe condition. • Varra Companies, Inc. Weld County USR 94 Western Sugar Reclamation Land Development Project November 2010 Acknowledged. Reclamation provides for slopes of 311:1V or flatter for areas above the anticipated final elevation to ten (10±) feet below that level. All affected lands not otherwise occupied by roads, structures, or continued surface disturbance in support of approved post extraction uses will be stabilized using the OMLR approved seed mixture, as detailed under OMLR Exhibit L - Table L- 1: Primary/Preferred Re-vegetation Seed Mixture. C. Sufficient drainage shall be provided so as to prevent water pockets or undue erosion. Grading shall be accomplished in such a manner that stormwater leaves the property at the original, natural drainage points. Runoff at any one (1) such point shall not normally be increased over historic flows. Increases over historic flows shall be allowed only when it is shown that the increased flows will not adversely impact USES or lands affected by such flows. Acknowledged and supported by a Stormwater Management Plan under an approved Colorado Department of health stormwater permit, a soil management plan as detailed under OMLR Exhibit E — Reclamation Plan and Exhibit I/J - Soils • and Vegetation Information of the OMLR permit. D. All excavated areas shall finally be graded in substantial conformity to the USE of the land proposed in the reclamation plan. Ridges, banks and mounds shall be graded so as to minimize erosion. Trees, shrubs, legumes, grasses or other ground cover shall be replaced in order to avoid erosion insofar as is practicable. Acknowledged and incorporated into the extraction and reclamation planning detailed in the relevant exhibits provided with this submittal. Sec. 23-4-310. Cancellation of Permit. The Board of County Commissioners shall have the power to cancel permits for violation of any of these regulations or conditions imposed by the Board. The • Board of County Commissioners shall cause to be served written notice upon the Varra Companies, Inc.

If the violations have not been corrected, the Board of County Commissioners shall direct the permittee to appear before the Board of County Commissioners, not less than ten (10) days nor more than thirty (30) days after the date of service notice. The Board of County Commissioners shall hold a hearing to determine the nature and extent of the alleged violation and shall have the power, upon good cause being shown, to cancel or revoke the permit heretofore issued to the permittee, to require the County or its agents to enter upon the premises and to take the corrective measures required by the Board of County Commissioners; the cost to be assessed against the permittee and his or her sureties. acknowledged • • Varra Companies, Inc. Weld County USR 96 Western Sugar Reclamation Land Development Project November 2010 • Questionnaire The following questions are to be answered and submitted as part of the USR application. If a question does not pertain to your use, please respond with 'not applicable,' with an explanation as to why the question is not applicable. The application requirements are outlined in Section 23-2-260 and Chapter 23, Article IV, Division 4, of the Weld County Code. The application shall contain the following information: 1. A detailed description of the method of mining operation. The description shall include: a. The types and numbers of structures that will be erected (build) on site including operation and processing equipment to be employed. The operation involves the surface extraction of aggregate. Surface soil is removed from the underlying deposit. Soil in excess of that required for reclamation is considered a resource. Extraction if • typically over the shoulder removal of the deposit utilizing (but not limited to) bulldozers, scrapers, front end loaders, and excavators. Extracted materials are typically transported by haul truck or conveyor to a designated plant area for processing. Operations require the flexibility of bringing to the designated plant site location (Tract A, as shown on OMLR Exhibit C-2: Extraction Plan Map) portable and temporary equipment, including a scale, scalehouse, wet processing plant, dry processing plant, portable concrete and/or asphalt plants; and/or recycling operations and related processing equipment. All equipment and plants are temporary and portable. Any permanent structures to be constructed on site and requiring and will apply for and obtain all required building permits through the Weld County Building Department prior to construction of regulated facilities. b. The number of shifts to be worked and the maximum number of employees. • Varra Companies, Inc. Weld County USR 97 Western Sugar Reclamation Land Development Project November 2010 Consistent with the adjacent Durham Project; an average of 9± • employees (6-12± at any one time) will work commonly in 8 to 12 hour shifts, except for those government jobs that require night time work, which may require up to three shifts over a 24 hour period. Other users include approximately (Range 20 - 200±) commercial and private haulers per day, including an occasional visitor or inspector. Commonly, operations will occur six (6) days a week, Monday through Saturday, however, occasionally, contracts or other project obligations may from time to time require a full seven day work week, including Sunday. Flexibility of both hours and days is a necessary aspect of the nature of maintaining and building Weld County's infrastructure and agricultural, residential, commercial and industrial communities, all of which place variable and unpredictable demands for earth derived construction materials. twenty—lour hours days at vt('cic ('21/7). 21 more precise estimate and lireailcdown is 111)1 rratlistic, and my nuntlx rs ret>rr seine tl are estimates that w ill V,uo by c ircnntstatnccs and market conditions 1)fl'alert at Iltr tine. c. Whether the operation will involve a wet or dry pit. • The operator requires discharge of groundwater to gain access to the necessary product in the most economically viable means possible. The pit will be maintained dry until such a time as extraction and basin slope reclamation and recoiling are completed for each Tract of the project. Extraction activities will continue to remove aggregate from approximately 15-25± feet along the southwest, to a mean depth of 35-40.0± feet at center, with a potential total depth to 70-80± feet along to the Cache La Poudre River. Since anomalous depths greater than 40± feet may occur, any extraction deeper than 40± feet in depth, may be extracted either dry, or wet. If extracted wet, a dredge may be utilized for the removal. d. County roads and bridges to be utilized, along with site entrance/exit points. (Coordinate with County Engineer). • None. Varra Companies, Inc. Weld County USR 98 Western Sugar Reclamation Land Development Project November 2010 • e. The size of the area and stages to be worked at any one time. Please refer to Parts 6, 7, and 8, below. The Tracts and areas to be worked are further identified in the OMLR Exhibit D - Extraction Plan and Exhibit C-2: Extraction Map. While all Tracts can be worked simultaneously, the rate, direction, and order of extraction will be determined by the strategies outlined in the extraction and reclamation plan exhibits, and by prevailing market conditions. f. A time table giving the periods of time and number of phases to be worked, which will be required for the various phases of the operation. Please refer to OMLR Exhibit D - Extraction Plan and Exhibit C-2: Extraction Map. While any Tract may commence at start-up, the anticipated sequence will occur as identified, below. Essentially, extraction will commence with Tract B, followed by Tracts C, D, and A. All tracts may be extracted concurrently * The total 102.87± acres permitted under the Weld County USR, and the Colorado Office of Mined Land Reclamation [OMLR] permit will have a total life of approximately twenty-five (25±) years, ending sometime in the year 2035, depending upon market demand. Approved reclamation for all open areas of extraction and disturbed land will be secured by an appropriate financial warranty as determined by the OMLR, and adjusted to cover circumstances as they occur over the life of the operation. Simultaneous extraction will tend to accelerate the overall completion of extraction activities and final reclamation of the location, to the extent that it occurs. * depending upon market demand. • Varra Companies, Inc. Weld County USR 99 Western Sugar Reclamation Land Development Project November 2010 g. The depth and thickness of the mineral deposit to be mined and the • thickness of overburden to be removed. Please refer to OMLR Exhibit D - Extraction Plan and Exhibit C-2: Extraction Map. Extraction activities will remove aggregate to a mean depth of 40.0± feet from the surface. Anomalous depths from 22.0± to 86.0± feet may occur. h. The proposed use of reclaimed lands and an explanation of the reclamation process. As indicated in OMLR Exhibit E — Reclamation Plan: As extraction progresses over planned areas in Tracts A, B, C and D; the resulting 1.25H4V slopes created during extraction will be concurrently modified by pushing the resulting pit bottom with a dozer until the resulting basin slopes conform with OLMR Rule 3.1.5(7). Lands above the anticipated static water level of the basins and within 10.0± feet • below the anticipated final water level of the basins will be graded to 31I:1V, or flatter. Lands below 10.0± feet from the anticipated final water level of the basins may approach 2H:1V. Naturally occurring slopes may exceed 2H:1V where not otherwise affected by extraction activities and will not be altered as part of reclamation unless necessary to facilitate the reclamation of affected lands. A Backfill Notice is included with this application as an Addendum at the back of OMLR Exhibit E - Reclamation Plan, to facilitate the fill of portions of the extracted lands for final end-use potentials beyond reservoir storage, which may include residential, commercial or industrial structures or uses otherwise approved, now or in the future, by Weld County, Colorado. The extent and nature of the reservoir represents the maximum build-out respective of optimal extraction of commercial product and resulting final slopes. All affected lands above the anticipated high water mark of the reservoirs will be capped with a minimum of six (6.0±) inches of soil, as supported by OMLR Exhibit I & J - Soils and Vegetation Information. Timing and use of soil is detailed further under OMLR Exhibit I & J - • Soils and Vegetation Information and Exhibit L — Reclamation Costs. Varra Companies, Inc. Weld County USR 100 Western Sugar Reclamation Land Development Project November 2010 Where compacted lands exist, and are to be revegetated, those • locations will be ripped prior to re-soil application. There are no known areas of compaction at the time of this application which would require such activity; and ripping remains a contingency of the application. The final land configuration results in four reservoir basins totaling 62.81± surface acres (refer to OMLR Exhibit F: Reclamation Map). The balance of unoccupied affected lands above the anticipated final water level will be stabilized where necessary utilizing the approved OMLR seed mixture, as detailed under OMLR Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture. Lands not otherwise occupied will be later developed to the highest possible end-use, and will likely comprise a mixed use which may include other agricultural uses as well as light residential, commercial or industrial uses. All affected lands remaining above the anticipated final water level of the ponds, and not otherwise occupied by existing or planned mixed uses, will be re-vegetated with the approved seed mixture(s) for general agriculture. To aid in the establishment and survival of the • preferred species, a wheatxwheatgrass sterile hybrid will be combined with either applied mixture as a substitute for the use of mulch. The formerly irrigated pasture was likely comprised predominantly of introduced species, and by neglect deteriorated to a near monoculture of kochia (Kochia scoparia). Since the blighted land is being replaced with predominantly native grasses, the target for release over the revegetated lands is based upon the establishment of a stabilizing cover whose foliar umbrella equals or exceeds 25 percent of the total area of the ground as measured three inches above the native soil on a square meter basis for typical areas of reclaimed cover achieved within five years subsequent to the completion of all extraction activities. Mixed use(s), other than industrial will occur and may include, but are not limited to: the retention of existing structures as desired for continued industrial - commercial use (as validated by any co-related and required Weld County Building Permits); the creation of unforeseen future structures, and for the use and development of on-site water resources. Since the area of surrounding lands is a mix of these uses, the site end use will retain these potentials. • Varra Companies, Inc. Weld County USR 101 Western Sugar Reclamation Land Development Project November 2010 • The rate of reclamation activity, including grading, soiling and revegetation will follow concurrently with extraction and the respective timetables identified for extraction under OMLR Exhibit D — Mining Plan. All timetables are contingent upon market conditions; therefore, a probable range of time is indicated. With extraction activities anticipated to take up to 20 years to complete, reclamation will add approximately five years to this estimate, bringing the anticipated life of the mine to 25± years, or the year 2035, depending upon market demand. i.

Bradford Janes, Professional Forester (Varra Companies, Inc.) 2. A statement which explains how the proposal is consistent with the Weld County Comprehensive Plan. The project conforms with Section 22-5-80 of Weld County's Comprehensive Plan: Commercial and Mineral Resource Deposits Goals and Policies. Expansion of human habitat and related pressures on area infrastructure is already evident near this location. The extraction of aggregate resource is in fact resource conservation, and tends to lessen the future density of subsequent urban development resulting from the inevitable expansion of human habitat, supporting uses, facilities and infrastructure. It is in fact this existing and ever expanding urbanization of agricultural land that constitutes • the greatest demand for this nonrenewable resource. Varra Companies, Inc. Weld County USR 102 Western Sugar Reclamation Land Development Project November 2010 Section 22-5-80 of Weld County's Code of Regulations is consistent • with Colorado law, both of which require that this resource must be recovered prior to other development which would otherwise impede access to it. The subsequent development of a diverse multiple land use potential at this location, when complemented with sound environmental parameters, as advanced under this proposal and the attending OMLR permit exhibits, is in keeping with the spirit and intent of the policies and goals of Weld County. Approval of the application will allow the resource to be accessed and utilized in a reasonable and orderly manner as required under both Colorado law and the Weld County Code of Regulations. The proposal complements the surrounding Industrial and Agricultural Districts. Resource recovery simply cannot occur over lands developed with houses and other structures. Where extraction occurs, the formerly blighted landscape will be replaced with water resources. Unlike other urban uses that intrude upon the agricultural districts, extraction is a transitional use, that leaves the final land in a configuration that prevents high density urban development, common to residential subdivision for example. • The resulting basins create visual and functional amenities that harmonize the scale, function, and vistas of surrounding agricultural lands and habitats. While residential development fragments wildlife habitat with increasingly larger building footprints for dwellings along with incompatible landscapes and fence-works; the results following extraction typically do not result in such permanent diminished landscapes, habitats or densities. The reclamation of extracted lands in fact often incorporate or introduce concepts often lacking in other developmental impacts. The more open design elements include the creation of edge effect resulting from the reintroduction of a more native landscape with enhanced aquatic margins that better complement and aid wildlife and scenic values. Overall, final reclamation of the extracted lands create features that better complement and lend themselves to the visual enjoyment of the surrounding community. The Vicinity Map shows those properties currently under permitted extraction, or otherwise owned or leased by companies that will eventually open those lands to extraction. The Future Compatibility: • Varra Companies, Inc. Weld County USR 103 Western Sugar Reclamation Land Development Project November 2010 The resulting reservoirs foreseen under the reclamation plan will result • in lower density development toward the Cache La Poudre River watershed. Agricultural conversion to other extraction and mixed industrial, commercial and residential uses are already evident as shown on the Vicinity Map. The water from the reservoirs can be made available for either urban or agricultural uses, but the basins alone are essential to providing a means to store and manage available waters. Any subsequent lower density development which may follow will still require necessary approvals from Weld County Building Department prior to the construction of any permanent structures, and from Weld County Planning, prior to the utilization of the parcels for any subsequent light residential, commercial or industrial uses beyond those already indicated under this submittal, and specifically indicated on OMLR Exhibit C-2: Extraction Plan Map. 3. A statement which explains how the proposal is consistent with the intent of the district in which the use is located. • Under Title 34, the State of Colorado and Weld County require the removal of a valuable mineral deposit from those lands prior to development. The extraction of a mineral deposit is an allowable use within the Weld County Industrial 1-3 District; which applies to the entire lands considered under this application. Resource recovery simply cannot occur over lands developed with houses and other structures. By this submittal, the owner proposes to reclaim formerly blighted and neglected lands through extracting the underlying aggregate and reclaiming the resulting basins for water storage. All previously affected lands reaffected by planned activities and remaining above the anticipated static water level of the resulting reservoirs will be returned to a beneficial and stabilizing cover of predominantly native vegetation; except where existing access roads, structures or other reasonable obstacles prevent it. The extraction is necessary to attain both the resource and end use objectives. Both extraction and the resulting basins are fully compatible with the surrounding lands. The planned activities over the • formerly blighted lands will return them to a beneficial use, resulting in Varra Companies, Inc. Weld County USR 104 Western Sugar Reclamation Land Development Project November 2010 improved visual and fiscal enhancement to both the principle and • surrounding land owners. 4. If applicable, a statement which explains what efforts have been made, in the location decision for the proposed use, to conserve productive agricultural land in the agricultural zone district. The identified soils are not Prime Irrigated Soils as designated on the U.S.D.A. Map titled, Important Farmlands of Weld County. Since extraction will result in basins and reclaimed to water storage reservoirs, the marginal soils overlying the aggregate resource will be salvaged and set aside for reclamation to the extent necessary and prescribed under the approved OMLR permit. Excess soil will be made commercially available. Replacement of the entire soil is not practical since resource recovery is dictated by the underlying deposit and the resulting basin area will generate more soil than is needed for the reaffected land remaining above the anticipated static water level of the basins and otherwise requiring revegetation. • When considering that the project location will be reclaimed to higher end uses while making available the resource for raw construction materials, the loss of some soil is unavoidable for the sake of the greater infrastructure needs of the community. All soil will find a productive use, either in the reclamation of affected lands not otherwise occupied by on-site access or other uses, or by the ever increasing urban communities, or local agricultural base. For a more comprehensive treatment of how the project meets the other goals and policies of the Comprehensive Plan and surrounding uses, please refer to Sec. 23-2-260, below. 5. A statement which explains there is adequate provision for the protection of the health, safety, and welfare of the inhabitants of the neighborhood and the County. The location as it is extracted will by its nature diminish any potential for fire or flood to surrounding lands. The localized access surrounding the basins, and the extraction itself resulting in basins below original ground will serve to cause direct precipitation to drain Varra Companies, Inc. Weld County USR 105 Western Sugar Reclamation Land Development Project November 2010 internally or otherwise serve to route or divert external overland flows • to existing waterways, and in general serve as a firebreak to surrounding lands. The nature of the extraction is intended to work the perimeters of the limits of extraction inward and away from area roadways and residences. By getting behind hillsides or below ground level, sounds from operations will be muted by the resulting topography. Internal access to operations is located below and away from nearby homes and area streets. Dust is minimized from leaving the project area by the extraction of moist materials in a project area managed under the authority of a Colorado Department of I lealth Fugitive Dust Permit. Waters are managed and protected under authority of the Colorado Department of Health stormwater permit requirements and Colorado Division of Water Resources. Health and Safety on site personnel and visitors are managed under authority of the federal MSHA program. All planned extraction, reclamation, phasing, timelines, life of the mine and warranty considerations are regulated under the State of Colorado • Division of Minerals and Geology, Office of Mined Land Reclamation (OMLR). Reclamation of affected lands follows closely behind extraction activities, as provided for under the Colorado Office of Mined Land Reclamation IOMI,R1 permit, and described in detail under OMLR Exhibit E - Reclamation Plan and Exhibit F - Reclamation Map, of that permit. Visual impacts during and subsequent to extraction and reclamation activities are eased by the location below and away from area residences and surrounded by existing or planned Industrial uses and activities. 6. A statement describing the existing surrounding land uses and explaining how the proposal will be compatible. The planned activities complement the surrounding City of Greeley Industrial uses to the west and north, including existing mining operations to the north and east. The location is flanked on the east • and south by properties in the A-Agriculture Zone. Southeast of Varra Companies, Inc. Weld County USR 106 Western Sugar Reclamation Land Development Project November 2010 planned extraction homes lie slightly farther away from operational • activity than they are for existing permitted extraction activity to their immediate north. South of the planned extraction homes line 16"' Street more than 400 feet from planned activity. Noise emanating from an 80 decibel source (e.g., a cone crusher) would be background residential level, or 55 decibels by the time it reaches 400 feet from the source. For the nearest residence to the southeast, extraction would not reach within four hundred feet until near the end of extraction operations, and again, would be slightly further away than activities at an existing operation to the immediate north of this residence. The residence is heavily buffered by a dense line of trees and shrubs between the permit area and the structure. With the exception of this single residence, all other sources are completely out of reach of any potential industrial noise levels, which operations are not anticipated to exceed. Each existing residence within the designated A—Agriculture zone is surrounded by trees and open space, further separating their residence from operational effects • within the adjacent I-3 zone. City of Greeley - Industrial I—M (medium intensity) lands lie to the north and west of the permit boundary. These lands are either vacant, or bounded by land disturbances such as settling basins, waste piles, or industrial buildings and support facilities or equipments. Other existing mining operations flank the permit boundary to the north and east. Planned activities within the permit boundary will not interfere with any of the surrounding Industrial lands or their current activities. Agricultural stock ponds, land leveling, use of equipment to manipulate land for crops, and other agricultural based activities are not uncommon in agricultural locations. As shown on the included Colorado Division of Reclamation Mining and Safety (CDRMS), Office of Mined Land Reclamation (OMLR) Exhibit C-2: Extraction Plan Map, the greater concentration of plant and processing activity, parking, machinery and equipment storage and stockpiling of materials is located in a manner that is removed from area residences and muted by area trees, open space and hillsides in the form of the flood plain escarpment. The location is approached internally and away from high • density residential areas and roads. Varra Companies, Inc. Weld County USR 107 Western Sugar Reclamation Land Development Project November 2010 • 7. A statement describing the existing land use. The location is blighted and dormant from its prior use as a receiving ground for effluent from the Western Sugar mill to the west. Existing oil and gas activities continue, but the remainder of the parcel is fallow. The extraction of a mineral deposit is an allowable use within the Weld County Industrial I-3. 8. Describe, in detail, the following: a. How many people (employees, visitors, buyers, etc.) will use this site? Consistent with the adjacent. Durham Project; an average of 9± employees (6-12± at any one time) will work commonly in 8 to 12 • hour shifts, except for those government jobs that require night time work, which may require up to three shifts over a 24 hour period. Other users include approximately (Range 20 - 200±) commercial and private haulers per day, including an occasional visitor or inspector. Commonly, operations will occur six (6) days a week, Monday through Saturday, however, occasionally, contracts or other project obligations may from time to time require a full seven day work week, including Sunday.

Support and employee activities and maintenance may occur sooner or later than those nominal hours outlined. Government contracts may require shifts and activities that are essentially non-stop for indefinite periods of time and seasons, depending upon the nature of work specified in those contracts, or by other operations obligations, which constitutes the greater need for operational flexibility respective of days and hours of operation. c. What type and how many animals, if any, will be on this site? No animal concentration applies to this operation, however, historic uses for cattle, horses, or other livestock, are not intended to be surrendered by this transitional use. • d. What kind (type, size, weight) of vehicles will access this site and how often? Trucks may vary from pick-up size to small trailers for the general public, to 15 ton tandem or 25 ton semi commercial haulers with an anticipated production departing the site of up to 4,000 tons per day. Generally, vehicle weights will fall within 85,000± pounds or less. Routes into and away from the property will access Ash Avenue, running north and south to 8th Street and 16th Street, respectively. e. Who will provide fire protection to the site?

Varra Companies, Inc. has rights to its own water that it will utilize for all project needs. Bottled water for drinking and sanitation will be available for employees and visitors. g. What is the sewage disposal system on the property? (Existing and proposed). While there are not existing sanitary facilities for the planned activities, prior to on—set of operations, the operator will provide two (2) commercially available port—o—lets near the entrance, accessible to both employees and visitors. First aid facilities will be available for emergency washing of body and eyes where required by MSIIA safety regulations. • h. If storage or warehousing is proposed, what type of items will be stored? As a precaution in the event of fuel from portable fueling trucks spills during refueling, absorbents will be stored on-site; as well as any necessary lubricants for heavy equipment, vehicles and machinery. All absorbents and lubricants will be secured in a locked waterproof container until used. i. Explain where storage and/or stockpile of wastes will occur on this site. No storage and/or stockpiling of wastes is anticipated for this location, except for the possible import and use of inert material for fill to • enhance post project end use development. Where debris or other Varra Companies, Inc. Weld County USR 110 Western Sugar Reclamation Land Development Project November 2010 unwanted material accumulates, for the purposes of sanitation, safety, • and general courtesy to our neighbors, all unwanted materials will be removed within thirty (30) days of deposition to a permitted land fill or other suitable location. Recyclable materials will be transported to permitted recycling plants or processed on-site to the extent recycling activities are approved under this application. All waste will be centralized and utilize an appropriate container, pallets, or be of a nature where it is stable in its present configuration or nature. j. Explain the proposed landscaping/screening for the site. The landscaping shall be separately submitted as a landscape plan map as part of the application submittal. Planning for extraction commonly incorporates existing or created vegetated buffers to complement adjacent lands and uses. Existing trees and ground cover along public road frontage and drainage ways will be preserved, maintained, and supplemented where necessary to aid in the stability of perimeter lands and minimize operational impacts. • The very nature of reclamation of these lands results in open spaces, diverse but less dense end uses, and complementary transitional vegetation that does not obstruct or conflict, but in fact complements, the surrounding lands and area wildlife. General buffering or screening will not occur during the extraction process, since the site lies below area homes and agricultural yards, while otherwise surrounded by more intensive industrial uses to the north and west of the location. Any planned processing or plant facilities will be located 400.0± feet or greater from any area road or existing residence not owned or controlled by the applicant, minimizing the effects of facility noise on area residents. At 400± feet or greater from a known source of 80± decibels (db), measured noise levels are at background residential, or 55± db. k. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. Timetable 23- • 2-260.C12. Varra Companies, Inc. Weld County USR 111 Western Sugar Reclamation Land Development Project November 2010 • Extraction will occur over approximately twenty-five (20) years, with concurrent reclamation following close behind extraction within each tract of land affected by operations. Completion of reclamation over all affected land will take up to an additional five (5) years following termination of extraction activities, for a total anticipated project life of 25 years; concluding sometime in the year 2035, depending upon market demand. Additional information is detailed in OMLR Exhibit C- 2: Extraction Map; Exhibit D - Extraction Plan; Exhibit E - Reclamation Plan; and Exhibit F - Reclamation Map. 1. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Reclamation for release by the Colorado Office of Mined Land Reclamation [OMLR] will signal the conclusion of the Use by Special Review activity, as specified in OMLR Exhibit E - Reclamation Plan and • Exhibit F - Reclamation Map. Subsequent to termination, the project locations will revert to the discretion of the landowner for continued multiple use development for water resources, residential, commercial, and industrial uses beyond those otherwise provided for in the application. m. Explain how the storm water drainage will be handled on the site. Since the project will result in the creation of basins, most water from direct precipitation will drain internally into the pits. Where outslopes from soil berms or road construction occurs, outslopes will be grassed to limit detachment and transportation of soil, thereby limiting and suspended solids from leaving the parcel, and generally diverting overland flows around affected lands and into existing drainageways. Existing drainageways lying outside the basins will not be altered, and the entire site will be managed under an approved Colorado Department of IIealth stormwater permit. • Varra Companies, Inc. Weld County USR 112 Western Sugar Reclamation Land Development Project November 2010 • n. Method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. Debris, junk and waste are not anticipated as part of project needs or activities. As stated above, where debris or other unwanted material accumulates, for the purposes of sanitation, safety, and general courtesy to our neighbors, all unwanted materials will be removed within thirty (30) days of deposition to an appropriate landfill or other suitable location. Recyclable materials will be transported to permitted recycling plants or processed on-site to the extent recycling activities are approved under this application. All waste will be centralized and utilize an appropriate container, pallets, or be of a nature where it is stable in its present configuration or nature. o. A statement delineating the need for the proposed use. • Earth products are in need directly proportionate to the growth of surrounding communities, who require these products to maintain road and highway infrastructure for local, county, state and federal work; as well as for subdivision development, oil and gas exploration and activities related to on-going facilities, and for area commercial and industrial development. In short, imagine Interstate 25 as a dirt road. The products are used extensively in concrete and asphalt for road projects; concrete for foundations, sidewalks, and general construction; soil for use in residential yards and developments; road base and fill to keep area roads fit for traffic; they provide materials to help support oil and gas activities across Weld County; and innumerable uses to keep the vitality of Weld County commerce and communities healthy and growing. p. A statement which explains the Use by Special Review area is not located in a flood plain, geologic hazard and Weld County Airport, overlay district area; or that the application complies with Chapter 23, Article V, Overlay District Regulations as outlined in the Weld County Code. • Varra Companies, Inc. Weld County USR 113 Western Sugar Reclamation Land Development Project November 2010 • The location is outside of any known geologic hazard. The location is within the Weld County Airport `Influence Zone.' The project does lie within the floodplain and a portion of the defined floodway of the Cache La Poudre River.

FREDERICK, COLO. 80516. March 5, 2010 Colorado Department of Public Health and Environment Water Quality Control Division WQCD-PE-B2 4300 Cherry Creek Drive South Denver, CO 80222-1530 Attention Permits and Enforcement Section Telephone (303) 692-3590 Subject: Storm Water Management Plan for Great Western Sugar Reclamation Pit # 120 • 1200 Ash Ave. Greeley, Co 80631 Notice. A Storm Water Management Plan (SWMP) is required before submittal of a Storm Water Permit Application with the Colorado Department of Health Water Quality Control Division. The following information serves as visible evidence of an in-place SWMP. The formatted information follows that indicated in the CDH Guidance Document of 14 June 1993 The Great Western Sugar Reclamation property is a parcel of level vacant land bordered by Ash Avenue on the West, residential and industrial property on the South, Birch Avenue and a permitted Sand and Gravel mining operation on the East and the Cache La Poudre River on the North. Due to the natural topography of the parcel, and general direction of flow, the storm water exits the site via the seep ditch traversing the center of the property. (North-North East) Subsequent material extraction activities of tracts #1, #2, and #3 will cause all storm water to drain into the pit, where a discharge pump will discharge the storm water along with the ground water into a settling pond prior t o discharge into the seep ditch and ultimately into the Cache La Poudre river. All lands contained within the boundary of tract #4 will be directed to the pit where it will settle before being discharged into the Cache La Poudre River The majority influence of water on site is from ground water, and not from upland. overland land flows Any overflow from the settling pond will be diverted East by a V-ditch to an adjacent 60 foot deep three acre settling pond currently being used for sand and gravel processing plant waters and a ready mix washout facility • Process water from the on site sand and gravel crushing plant will also be directed via V-ditch to the off site three acre settling pond Any storm water run off from the adjacent property West of the property will be directed to a • detention facility on the North West corner of the property to allow for settlement prior to drainage into the excavated pit of tract #1 for additional settling. (Rip-Rap/straw bales/silt fence will be used to control water erosion) Ground water along with the storm water run off will be discharged to the settling pond before being discharged to the seep ditch and ultimately to the Cache La Poudre River. I. SITE MAPS Current site maps are located in the Storm Water Permit Application. --- Access and haul roads. Materials handling area. (Use of conveyors will be used to transport material from the excavation tracts to the processing area). --- Structural control measures reduces pollutants in the storm water run off and ground water --- Area used for processing. --- Date the map was revised 2/08/2010 II. DESCRIPTION OF POTENTIAL POLLUTANT SOURCES/MATERIAL The primary pollutant is sediment created by exposure and movement of materials. Secondary potential pollutants are fuel and oil leaked from traversing vehicles and heavy equipment. Minor spillage can occur at the mobile fueling station and/or fuel storage tank. The conveyors along • with the processing plant are powered by electric energy and are not considered a pollutant source. A tertiary source of pollutants is spent containers, grease tubes and employee vehicles III. STORM WATER QUALITY CONTROLS A. SWMP Administrator: - All duties for the management and control of storm water via this plan are delegated by and the responsibility of Christopher L. Varra. President B. Materials Handling and Spill Prevention. - All materials are handled internally and are not anticipated to breach the internal drainage of the site. Control of soil is detailed under part C. below. Stockpile material at the processing location is deterred from exiting the site by its large size. Anticipated chemical pollution would be from minor leaks of diesel fuel, gasoline, or oils (lubricants, hydraulic fluids, crankcase oil). Equipment leaks are checked daily and repairs ordered when leaks are observed Service personnel make repairs on heavy equipment off site Oil from all locations (including filters and oil changes) is recycled to a waste oil facility. Where noticeable leaks are observed on the ground, the material is removed by front-end loader and stored in a berried secured area. There will be incidents of this kind. If larger spills occur. the material will be placed in covered leak-proof containers and hauled to an appropriate landfill certified to dispose of contaminated soil/overburden Absorbents are maintained with the refueling station to attend to any incidental spills. C. Erosion and Sediment Controls: - Graveled haul roads control sediment. Which, prevent escape of material due to storm water. Where road surfaces are compact, treatment of those • areas will not be necessary. Roads are relatively flat and do not support significant runoff. Primary concerns will be to control soil erosion. Sediment is controlled by the topography, which prevents escape of materials due to storm water. Water trucks are used to keep haul roads damp in order to control the dust Sediment that settles in the excavation pits is recycled to the processing plant D. Testing of discharges: - Testing will be conducted as directed by the Colorado Department of Health and Environment (Water quality control division) E. Stored fuels and oils: - Ali fuels and oils will be stored on the mobile fueling station or off site. All other housekeeping measures, such as, keeping grounds free of trash, empty containers, or potential pollutants, are performed daily. Trash is secured in covered leak proof containers until removed to an appropriate landfill for disposal. F Storm Water Control Inspections. Inspections of all storm water controls are made periodically throughout the year. with a minimum of 2-recorded inspections one in the spring and one in the fall to verify the integrity of the site G.

Western Sugar Reclamation Land Development Project 1 OMLR 112 Permit Application 2010 Exhibit D- Extraction Plan • Summary Status of Affected and Unaffected land as of this Amendment (Exhibit C-1: Existing Conditions and Exhibit C-2: Extraction Plan Map): Of the 128.18± Acres of lands comprising the parcel boundary, 25.31± acres of zoned commercial/industrial lands within the City of Greeley are not included in the permit boundary, resulting in total permit area of 102.87± acres remaining in the Weld County I-3 Industrial Zone District. Of the 102.87± Acres to be permitted the nature of each aspect of the affected lands are as follows: 20.84± Acres of Planned Extraction — Tract A 12.88± Acres of Planned Extraction — Tract B 29.31± Acres of Planned Extraction —Tract C 11.99± Acres of Planned Extraction —Tract D 75.02± Acres of Planned Extraction— TOTAL Comprised of: 62.81± Acres - Completed basins (within Total Area of Extraction) — total area at anticipated static water level. 12.21 Acres - requiring resoilinq and revegetation between the anticipated static • water level of the completed basins and the extraction limits And a remainder of: 27.85± Acres — previously affected lands remaining outside of the extraction limits, comprised of: 4.60± Acres - Internal Access Roads 1.23± Acres — disturbed by existing above ground oil and gas facilities 22.02± Acres outside area of extraction (extraction limits) requiring revegetation only. NOTE Well: All lands within the 102.87± acre permit area are to be considered as affected lands under C.R.S. 34-32.5-103(1) respective of this permit application and any subsequent permit revisions or amendments to the permit as originally approved. Exhibit C-1: Existing Conditions and Exhibit C-2: Extraction Plan Map, show the location, extent, and features described above; along with features made obvious in the included aerial image of the permit location and surrounding lands. The maps also show all man made structures located within 200 feet of the permit boundary (i.e., affected lands); including creeks, roads, buildings, oil and gas wells and lines, and power and communication lines on and within 200 feet of the affected land; as well as all adjoining surface owners of record. A listing of the adjoining surface owner's names and addresses are listed under Exhibit C — Text, correlated with those shown in the • aforementioned map. Varra Companies, Inc. Western Sugar Reclamation Land Development Project 2 OMLR 112 Permit Application 2010 Exhibit D- Extraction Plan • The site lies within the flood plain of the Cache La Poudre River to the north, and overlies bedrock that varies in depth from 20-25± feet along the southwest portion of Tract B, to increasing depths to the north and east averaging 35-40± feet and dropping to a potential depth of 70-80± feet along the Poudre River. Geological conditions are based in part from a Preliminary Feasibility Report for Aggregate Reserves at the Greeley Facility, as prepared by Applegate Group, Inc. in January 2005 for The Western Sugar Cooperative. Accordingly, test bores suggest a mean static ground water level of 8.0± feet and generally variable from 5± to 13± feet or deeper from the surface. Alluvial groundwater is unconfined and flows east and 'slightly toward' the Poudre River. As stated in the report, the underlying bedrock is likely to be a hard grey to sandy brown clay-stone or tightly cemented sandstone consistent with strata of the Laramie Formation or Pierre Shale which outcrop north and west of the site. Bedrock contour maps were utilized to approximate elevations resulting from extraction and corresponding basin depths as shown on the Extraction Plan and Reclamation Plan maps. A bedrock 'mound' is evident in the southwest portion of the map underlying the majority of the designated Tract B. • Method of mining is presently dry, with discharge of waters conducted under an approved Colorado Dept. of Health discharge permit. Extraction utilizes, but is not limited to, diverse heavy equipment; including, backhoes, scrapers, excavators, dozers and related heavy equipment. A grader and water truck maintain access throughout operations. Access is clearly indicated under Exhibit C-1: Existing Conditions and Exhibit C-2: Extraction Plan Map. Primary access is approximately 657.0± feet east of Ash Avenue behind a commercial- industrial lot owned and controlled by Varra Companies, Inc. The lot itself is flanked on its western boundary by Ash Avenue. Access from the permit boundary will be through the existing lot. The commercial industrial lot is surrounded by other industrial lands and uses when turning from that lot either north or south onto Ash Avenue itself. Wet and/or dry plant processing operations will occur near the eastern permit boundary on previously affected lands comprising the last area of extraction identified as Tract A on Exhibit C-2: Extraction Plan Map. The specific plant operations will be clarified by a later Technical Revision to the Division, but are generally comprised of portable equipment. A small wash pond may be established within Tract A or an adjacent existing pit, or as otherwise identified in the correlated Technical Revision. Materials may be processed and scaled at the adjacent Durham Project until similar • facilities are established within the approved permit boundary. Provisions for a materials processing plant, a concrete and/or asphalt batch plant, and periodic use of recycling facilities and related plant, remain a necessary inclusion to operations under Van-a Companies, Inc. Western Sugar Reclamation Land Development Project 3 OMLR 112 Permit Application 2010 Exhibit D- Extraction Plan • this permit. Any material processing facilities, recycling facilities, recycling plant, or concrete and/or asphalt batch plant locations will be determined and identified in a later Technical Revision to the approved permit, and are mentioned for purposes of establishing these activities as approved uses under this submittal. Additionally, adjacent lands may have asphalt or concrete batch plant operations serviced by the permit, but will occur on adjacent lands under a separate approved municipal permit with the City of Greeley, and such operations and attending stockpiling or other surface disturbances or features should not be considered part of this permit or extraction activities requiring permitting under the Act. Known structures and landowners, including above and below ground utility owners, located on and within 200± ft. of the permit boundary are shown on Exhibit C-1: Existing Conditions and Exhibit C-2: Extraction Plan Map. Exhibit S — provides certification from a registered professional engineer that these structures will not be harmed by planned operations; nor has any evidence of harm evidenced itself over the nearly 60± years of operations at the adjacent Durham Project. A 1600± linear foot standard morphing extraction front is comprised of a 1.25H:1V face along an approximate 800-1200± linear foot advancing; wall with trailing side slopes up to 400 total linear feet combined along either side of the advancing wall where it serves • to define the predetermined boundary of the extraction limits shown on Exhibit C-2: Extraction Plan Map. Concurrent grading follows immediately behind the trailing side slopes as they occur along the extraction limits. This morphing extraction front, with its advancing wall, trailing side slopes, and concurrent reclamation along the extraction limits is approximate for all active Tracts. The 1600± linear foot total extraction front is 'morphing' in that the total linear feet of the front will not exceed 1600± linear feet, however, the advancing wall and side slopes may deviate from the 'standard' lengths described above. For example: If the advancing wall is only 600± linear feet, trailing side slopes may have a combined length pending finished grading of up to 1,000± linear feet. Another example is if the advancing wall is 1,400± linear feet long, there is only 200± linear feet of trailing wall, and operations must be more Johnny on the spot in keeping up with concurrency in this configuration. So the 'morphing of the front generally affects the pace of concurrent reclamation of the trailing wall. Extraction activities will continue to remove aggregate from approximately 15-25± feet along the southwest, to a mean depth of 35-40.0± feet at center, with a potential total depth to 70-80± feet along to the Cache La Poudre River. Since anomalous depths greater than 40± feet may occur, any extraction deeper than 40± feet in depth, may be extracted either dry, or wet. If extracted wet, a dredge may be utilized for the removal. • Regardless, all final basin (pond) slopes will conform at a minimum to Rule 3.1.5(7). Varra Companies, Inc. Western Sugar Reclamation Land Development Project 4 OMLR 112 Permit Application 2010 Exhibit D- Extraction Plan • The general direction of extraction activities over the diverse Tracts is shown on Exhibit C-2: Extraction Plan Map. Extraction will occur no closer than 10± feet from the permit boundary, man made structures, easements and right-of-ways; except for well heads and above ground oil and gas facilities. Extraction will occur to within 25± feet of well heads and related above ground facilities. Extraction around well heads will be concurrently backfilled to maintain a 100± foot buffer from the balance of extracted lands. At all times, safety will take precedent and over-ride all other conditions in time with a matter of safety or emergency respective to and all aspects of the approved permit. Tracts are used instead of Phases to describe the activities, since each Tract can be accessed concurrently instead of sequentially with the other; and per Exhibit L — Reclamation Costs, accelerated extraction only serves to decrease the overall reclamation liability and accelerate final reclamation and site stabilization of the property as a whole. Therefore, any method that accelerates the above timetable will be utilized, based upon market conditions and the capacities of the operator. Because the permit area is entirely affected and degraded from past uses, the method of extraction functions to effect reclamation first on the most disturbed portions of the parcel; essentially where soil is absent, hence reclaiming previously spoiled lands that • might not otherwise be reclaimed. Essentially, since Tracts A and B are void of soil, Tract B will be extracted first while plant operations are established over Tract A. Extraction will then follow over Tracts C, D, and A. Simultaneous extraction with Tract B in other Tracts may occur by simply providing additional warranty for Standard Extraction Fronts, as previously described above and detailed under Exhibit L — Reclamation Costs. Set up of Plant operations and on-set of extraction activities in Tracts A and B, respectively, will better allow for the use of over the shoulder removal of soil from Tracts C and D to effect the reclamation of the designated affected lands in Tracts A and B. The timetable for extraction, commencing approximately fall to winter 2010; is estimated to take 20± years combined followed by an additional five years to complete reclamation; or a total estimated life of the mine of 25± years; ending approximately winter 2035-36. • Varra Companies, Inc. Western Sugar Reclamation Land Development Project 5 OMLR 112 Permit Application 2010 Exhibit E — Reclamation Plan • . 6.4.5 EXHIBIT E - Reclamation Plan (1) In preparing the Reclamation Plan, the Operator/Applicant should be specific in terms of addressing such items as final grading (including drainage), seeding, fertilizing, revegetation (trees, shrubs, etc.), and topsoiling. Operators/Applicants are encouraged to allow flexibility in their plans by committing themselves to ranges of numbers (e.g., 6"-12" of topsoil) rather than specific figures. (2) The Reclamation Plan shall include provisions for, or satisfactory explanation of, all general requirements for the type of reclamation proposed to be implemented by the Operator/Applicant. Reclamation shall be required on all the affected land. The Reclamation Plans shall include: (a) A description of the type(s) of reclamation the Operator/Applicant proposes to achieve in the reclamation of the affected land, why each was chosen, the amount of acreage accorded to each, and a general discussion of methods of reclamation as related to the mechanics of earthmoving; (b) A comparison of the proposed post-mining land use to other land uses in the vicinity and to adopted state and local land use plans and programs. In those instances where the post-mining land use is for industrial, residential, or commercial purposes and such use is not reasonably • assured, a plan for revegetation shall be submitted. Appropriate evidence supporting such reasonable assurance shall be submitted; (c) A description of how the Reclamation Plan will be implemented to meet each applicable requirement of Section 3.1; (d) Where applicable, plans for topsoil segregation, preservation, and replacement; for stabilization, compaction, and grading of spoil; and for revegetation. The revegetation plan shall contain a list of the preferred species of grass, legumes. forbs, shrubs or trees to be planted, the method and rates of seeding and planting, the estimated availability of viable seeds in sufficient quantities of the species proposed to be used, and the proposed time of seeding and planting; (e) A plan or schedule indicating how and when reclamation will be implemented. Such plan or schedule shall not be tied to any specific date but shall be tied to implementation or completion of different stages of the mining operation as described in Subparagraph 6.4.4(1)(e). The plan or schedule shall include: (I) An estimate of the periods of time which will be required for the various stages or phases of reclamation; (ii) A description of the size and location of each area to be reclaimed during each phase; and (iii) An outline of the sequence in which each stage or phase of reclamation will be carried out. (The schedule need not be separate and distinct from the Reclamation • Plan, but may be incorporated therein.) (f) A description of each of the following: Varra Companies, Inc. Western Sugar Reclamation Land Development Project 1 OMLR 112 Permit Application 2010 Exhibit E — Reclamation Plan • (i) Final grading - specify maximum anticipated slope gradient or expected ranges thereof; (ii) Seeding - specify types, mixtures, quantities, and expected time(s) of seeding and planting; (iii) Fertilization - if applicable, specify types, mixtures, quantities and time of application; (iv) Revegetation - specify types of trees, shrubs, etc., quantities, size and location; and (v) Topsoiling - specify anticipated minimum depth or range of depths for those areas where topsoil will be replaced. This application provides substantial detail of features utilizing aerial photography that is ortho-rectified to approximately 1.0± percent of surveyed accuracy. This highly accurate and detailed portrayal of the mining and reclamation is visible under Exhibit C- 1: Existing Conditions and Exhibit C-2: Extraction Plan Map, and, Exhibit F — Reclamation Map. How reclamation will occur over affected lands is further detailed under Exhibit L — Reclamation Costs. As extraction progresses over planned areas in Tracts A, B, C and D; the resulting 1.25H:1V slopes created during extraction will be concurrently modified by pushing the • resulting pit bottom with a dozer until the resulting basin slopes conform with Rule 3.1.5(7). Lands above the anticipated final water level of the basins and within 10.0± feet below the anticipated final water level of the basins will be graded to 3H:1V, or flatter. Lands below 10.0± feet from the anticipated final water level of the basins may approach 2H:1V. Naturally occurring or previously established slopes may exceed 2H:1V where not otherwise affected by extraction activities and may not be altered as part of reclamation unless necessary to facilitate the reclamation of affected lands. A Backfill Notice is included with this application as an Addendum at the back of Exhibit E — Reclamation Plan, to facilitate the fill of portions of the extracted lands for final end- use potentials beyond water storage, which may include residential, commercial or industrial structures or uses otherwise approved, now or in the future, by Weld County, Colorado or any subsequent municipality resulting from annexation. The extent and nature of the water storage basin represents the maximum build-out respective of optimal extraction of commercial product and resulting final slopes. All affected lands between the extraction limits and remaining above the anticipated high water mark of the basins will be capped with a minimum of six (6.0±) inches of soil, as supported by Exhibit I & J — Soils and Vegetation Information. Timing and use of soil is detailed further under Exhibit I & J - Soils and Vegetation Information and Exhibit L — Reclamation Costs. Where compacted lands exist, and are to be • revegetated, those locations will be ripped prior to re-soil application. There are no Varra Companies, Inc. Western Sugar Reclamation Land Development Project 2 OMLR 112 Permit Application 2010 Exhibit E — Reclamation Plan • known areas of compaction at the time of this application which would require such activity; and ripping remains a contingency of the application. The final land configuration results in four reservoir basins totaling 62.81± surface acres (refer to Exhibit F: Reclamation Map). The balance of unoccupied affected lands above the anticipated static water level will be stabilized where necessary utilizing the seed mixture under Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture and Costs. Lands not otherwise occupied will be later developed to the highest possible end-use, and will likely comprise a mixed use which may include other agricultural uses as well as light residential, commercial or industrial uses. All affected lands remaining above the anticipated final water level of the basins, and not otherwise occupied by existing or planned mixed uses, will be re-vegetated with the approved seed mixture(s) for general agriculture. Since the existing pasture comprised predominantly of weeds is being replaced predominantly with native grasses, the target for release of revegetated lands is based upon the establishment of a stabilizing cover of predominantly native vegetation whose foliar umbrella equals or exceeds 20 percent of the total area of the ground as measured three inches above the native soil on a square meter basis for typical areas of reclaimed cover achieved within five years subsequent to the completion of all extraction activities. • Mixed use(s), other than general agriculture will occur and may include, but are not limited to: the retention of existing structures as desired (e.g., processing facilities and plant(s), concrete batch plant, asphalt batch plants, recycling facilities and related operations, shop, scale-house/office, and supporting facilities (fuel depots, parking areas, oil and gas facilities access, etc.) for continued industrial - commercial use (as validated by any co-related and required Weld County Building Permits); the creation of unforeseen future structures, and for the use and development of on-site water resources. Since the area of surrounding lands is a mix of these uses, the site end use will retain these potentials. The rate of reclamation activity, including grading, soiling and revegetation will follow concurrently with extraction and the respective timetables identified for extraction under Exhibit D — Extraction Plan. All timetables are contingent upon market conditions, therefore, a probable range of time is indicated. With extraction activities anticipated to take up to 20 years to complete, reclamation will add an approximately five years to this estimate, bringing the anticipated life of the mine to 25± years, or the year 2035. A Backfill Notice follows this page, as part of this Exhibit. The use of inert fill will facilitate the timely fill of selected portions of the project area as desired, and related • reclamation of affected lands and use of related water resources (refer to Exhibit L — Reclamation Costs). Varra Companies, Inc. Western Sugar Reclamation Land Development Project 3 OMLR 112 Permit Application 2010 Exhibit E — Reclamation Plan • BACKFILL NOTICE Inert fill may be imported or utilized from existing sources, along with processing fines and reject material to fill portions of Tracts A, B, C, and D —the extent and location of which will be field determined during final reclamation in order to advance alternative end-use potentials for post extraction development. The estimated total volume of fill will not exceed the total volume of material extracted from the location, or as otherwise determined. The date of fill activity will commence at onset of approval of this application, and continue for the life of the project, estimated at 25±years. Material will be mixed with on-site processing fines and reject prior to fill to eliminate void spaces, where necessary. The filled portions of a given tract will be re-vegetated with the approved seed mix where it meets the conditions described under Exhibit E—Reclamation Plan. All material either extracted on site, or imported to the site, will be handled in such a manner so as to prevent any unauthorized release of pollutants to the surface drainage system. No unauthorized release of pollutants to groundwater shall occur from any materials mined, handled or disposed of within the permit area. • I, Christopher L.

(2) If the operation is expected to directly affect surface or groundwater systems, the Operator/Applicant shall: (a) Locate on the map (in Exhibit C) tributary water courses, wells, springs, stock water ponds, reservoirs, and ditches on the affected land and on adjacent lands where such structures may be affected by the proposed mining operations; (b) Identify all known aquifers; and (c) Submit a brief statement or plan showing how water from de-watering operations or from runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater (and, where applicable, control pollution in a manner that is consistent with water quality discharge permits), both during and after the operation. (3) The Operator/Applicant shall provide an estimate of the project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. • (4) The Operator/Applicant shall indicate the projected amount from each of the sources of water to supply the project water requirements for the mining operation and reclamation. (5) The Operator/Applicant shall affirmatively state that the Operator/Applicant has acquired (or has applied for) a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division at the Colorado Department of Health, if necessary. (1) Operations will not adversely affect surface and groundwater systems. The manner and method of extraction is detailed under Exhibit D — Extraction Plan. Anticipated effects on surface flows are anticipated to be minor to none. Essentially, the flood plain covers the property and unless under flood conditions, upland overland flows are generally diverted by existing access roads or grassed drainage channels, or drain internally into existing or planned basins. (2) (a) Please refer to Exhibit C-1: Existing Conditions Map. (b) The known aquifer under the site is the stream alluvium. (c) Discharge water will be dissipated with hard surface riprap or established grassed waterways. Other waters are retained by internal pit drainage, directed by vegetated berms or established waterways or through the maintenance or establishment of a stabilizing cover of vegetation, or as otherwise established under an approved Colorado Department of Health stormwater permit and/or • stormwater discharge permit. Van-a Companies, Inc. Western Sugar Reclamation Land Development Project 1 OMLR 112 Permit Application 2010 Exhibit G — Water Information • (3) The three components of the project water requirements are water removed with the product, dust control, and evaporation from exposed ground water. Dust will be controlled using truck sprinklers, and the estimated frequency is one load per day. At 2,500 gallons of truck capacity, the annual demand is 2.80 acre-feet. After the water table is encountered, the water removed with the estimated 800,000 tons of product is 23.55 acre-feet per year. The estimated net evaporation is 1.419 feet per year. At the maximum potentially exposed ground water of 62.81 acres, the annual evaporation is 89.13 acre-feet. The monthly distribution of these estimates is shown in the following table. The reclamation plan provides that the pits will be lined after being mined. The lined pits will not require replacement water and will be used for storage. There may be incidental demand for water to establish vegetation on the site after lining is completed. However, the ultimate demand for water will be zero.

Any impoundment or pond that holds water at an elevation above the surrounding water table will have the potential of increasing the water table elevation (mounding) at some distance from the pond, which is determined by • the total groundwater-pond head difference. For ponds that are large in areal extent the distance to no influence on the upstream side is usually less than the downstream side as the head difference will be less based on the water table's hydraulic gradient. The influence imposed by the pond can be estimated by one dimensional unconfined flow solutions presented by McWhorter and Sunada, 1977. Numerical models can be used but we have found model results generally agree well with analytical solutions. An example calculation using a one dimensional unconfined flow equation is presented as Attachment A. In most unconfined flow regimes we consider the distance to no influence (or measurable influence) generally to be on the order of 600 feet. For your operations it appears the pond and groundwater head difference is on the order of five feet. Given this scenario at 100 and 300 feet from the pond the resulting mounding would be four and two feet, respectively. We advise that great care be given when constructing water impoundments (lined or unlined) within 100 feet of any subsurface structures. We have evaluated the affects of impermeable barriers on groundwater hydrology by using the analytical model TWODAN. We simulated a uniform flow field using aquifer properties typically associated with sand and gravel deposits. We then simulated an impermeable barrier within the flow field. The results indicate that the groundwater hydrology is modified but only severely in very close proximity to the barrier. Upstream of the barrier the hydraulic gradient will increase and will decrease downstream of the barrier. Hydraulic gradient changes of between one and two feet are observed within 15 feet of the barrier • wall but are negligible at any significant distance from the hydraulic structure. A P.O.

The Operator/Applicant shall include in this Exhibit, a description of the game and non-game resources on and in the vicinity of the application area, including: (a) a description of the significant wildlife resources on the affected land; (b) seasonal use of the area; (c) the presence and estimated population of threatened or endangered species from either federal or state lists; and (d) a description of the general effect during and after the proposed operation on the existing wildlife of the area, including but not limited to temporary and permanent loss of food and habitat, interference with migratory routes, and the general effect on the wildlife from increased human activity, including noise. (2) The application may be reviewed and commented upon by the State of Colorado Division of Wildlife (DOW). If the DOW has comments, they must be provided prior to the end of the public comment period specified in Subsection 1 .7.1(2)(a) to be considered by the Board and Office. The Colorado Division of Wildlife inspected the project location on 16 February 2010 • and identified the game and non-game species that may occur or migrate over the location, and any potential impacts. Recent policy of the Division of Wildlife no longer provides for a pre-submittal report. It is our understanding in discussing the location with District Wildlife Manager, Brandon Muller; the planned project extraction and concurrent reclamation will not have a deleterious effect on area resident wildlife and wildlife visitors to the location. Wildlife residents and visitors observed on area lands, but not on site at the time of the inspection, include the occasional fall/winter roosting of Bald Eagle on nearby mature cottonwood trees, but with no evidence of nesting. Other resident birds of prey have been seen in the area, including hawks and owls. Shorebirds and waterfowl also occur in the area both seasonally and year around, and commonly sited are pelican in spring to late summer, while cormorant and great blue heron may be observed pretty much year around. Game species such as white tailed deer will traverse the river bottom and open spaces nearby; as will other fur bearers such as fox, rabbit, and squirrels; non- game species such rodents; and passerines (song birds). No significant natural habitat or habitat loss is anticipated by planned operations due to the blighted condition of the designated land from past use and neglect. The pending DOW report is anticipated to support our understanding that there is little if any potential for negative impacts to wildlife resulting from planned operations. • Further, planned reclamation is consistent with DOW recommendations made at the time of the inspection, and will serve to provide a number of benefits to various wildlife species, especially waterfowl, including a return of native vegetation, cover, and Varra Companies, Inc. Western Sugar Reclamation Land Development Project OMLR 112 Permit Application 2010 Exhibit H — Wildlife Information • creation of water bodies that will serve as additional sources for food, cover, and resting surfaces. The clover leaf design and limitations to the extraction limits due to natural and man-made obstacles will help to add the desired irregularity of shorelines desired by diverse wildlife species. The planned seed mixture will further add to the diversity of height, form, color and function of the resulting vegetative cover. Additionally, an inspection of the location for any potential Preble's meadow jumping mouse and Ute ladies' tresses orchid was performed 28 July and 5 August 2009; as detailed in a report of 2 September 2010 by Dr. Mark Bakeman of Ensight Technical Services, Inc. Subsequent review by U.S. Fish and Wildlife Service cleared the location of the potential for occurrence as indicated by the stamped determination of 22 April 2010 on the 20 April 2010 submittal of the Bakeman report. Finally, the site was traversed and inspected with the U.S. Army Corps of Engineers on 1 December 2009, as detailed in a report of 8 January 2010 by Dr. Mark Bakeman of Ensight Technical Services, Inc. The U.S. Army Corps of Engineers in its correspondence of 15 January 2010 concurred that no waters of the United States are located within the planned activity of the permit location.

Such description will address suitability of topsoil (or other material) for establishment and maintenance ofplant growth. The above information shall satisfy "completeness" requirements for purposes of determination of date of filing. (2) If necessary, at its discretion, the Board may require additional information on soils or other growth media to be stockpiled and used in revegetation to be submitted subsequent to the filing and notification of "completeness" of the application. 6.4.10 EXHIBIT J - Vegetation Information (1) The Operator/Applicant shall include in this Exhibit a narrative of the following items: (a) descriptions of present vegetation types, which include quantitative estimates of cover and height for the principal species in each life-form represented (i.e., trees. tall shrubs, low shrubs, grasses, forbs); • (b) the relationship of present vegetation types to soil types, or alternatively. the information may be presented on a map; and (c) estimates of average annual production for hay meadows and croplands. and carrying capacity for range lands on or in the vicinity of the affected land, if the choice of reclamation is for range or agriculture. (2) The Operator/Applicant shall show the relation of the types of vegetation to existing topography on a map in Exhibit C. In providing such information, the Operator/Applicant may want to contact the local Soil Conservation District. Exhibit I & J — Soils & Vegetation Map, identifies the type and extent of soils over the project site relative to the areas designated for resource recovery. While the native vegetation has been replaced by agricultural practices prior to the establishment of irrigated pasture grass and other disturbances to the surface, the range site description for the single soil type covering the majority of the location is included at the back of this exhibit. The range site description (Salt Meadow), and the narrative description of vegetation in undisturbed conditions in the Unit 3 soil description (also attached), indicate what could grow on the identified soil under native undisturbed soil conditions. This information was utilized to create the seed mixture proposed under Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture. A portion of these soils will be used in an over the shoulder method to resoil the completed banks of Tract A, and • finally, Tract D; or park the soil in stockpiles lining the basin perimeter until ready for application in a manner more fully described below. Varra Companies, Inc. Western Sugar Reclamation Land Development Project 1 OMLR 112 Permit Application 2010 Exhibit I & J — Soils & Vegetation Information It should be noted that the pasture grass previously established when a pivot irrigation system was operating is now deteriorated into a monoculture of kochia (Kochia scoparia). This is the condition over the balance of lands, the majority of which were disturbed and over significant portions the soil removed by past practices. At this time there are no preferred species or cover typifying the site. The reclamation target will be to establish a stabilizing foliar cover of preferred vegetation (refer to seed mixture) of approximately 20 percent measured at the stem three inches above the ground surface respective of the foliar diameter of the established grass species utilizing standard vegetation cover analysis. For clarity, topsoil is generally regarded as the plow layer (upper six inches) on agricultural soils, or the A-1 soil profile horizon otherwise. The solum, or soil includes the topsoil plus all other material above the regolith of the parent rock and generally no deeper than the depth of rooting of perennial plants or which otherwise meets the definition of soil. One soil differs from another soil by its unique properties and characteristics (such as horizon profile development, structure, texture, color, percent organic matter, chemical composition, etc.) and is identified as such by soil scientists, and described in NRCS Soil Survey documents. The affected soils to be extracted as permitted are designated under the soil survey to • fall entirely under Unit 3: Aquolls and Aquents, gravelly substratum (refer to extracts and tables from the 1980 Weld County Soil Survey — Southern Part). Occurring in flood plain locations, as they do at this location, while described as 'deep,' would only apply to the Aquolls, a Mollisol that appears to be a minor component, while the majority of the location is more characteristic of an Aquent or Entisol, which are actually poorly formed soils lacking a typical profile or horizon development, in part due to alluvial flooding which both scours and lays down sediment of diverse textural classes over time, but which lacks the appearance of an Inceptisol which is commonly associated with flood plain locations. This is further evidenced by the lack of a soil series soil horizon profile description in the soil survey for these soils. Essentially, previous beet production activities created settling basins over the southern half of the location in order to receive waters from the nearby sugar mill. The activity removed the soil, including the upper layers of the soil profile where a plow layer may have developed. The remaining acres found north of the oil and gas service road that bisects the permitted parcel, may have poorly developed soils whose depths vary from zero to eight inches. While anomalous pockets of deeper soil depths may occur, for purposes of this submittal, we will assume a soil depth to the plow layer of six inches over the north half of the affected lands, excluding any obvious previously disturbed ground • where soil has been removed (trenches, structures, etc.). The location evidenced the use of a pivot irrigation system over this portion of the parcel, most likely for use in Varra Companies, Inc. Western Sugar Reclamation Land Development Project 2 OMLR 112 Permit Application 2010 Exhibit I & J - Soils & Vegetation Information • establishing irrigated pasture grass, as the adjacent lands bordering the permit boundary to the west were used for several decades as a cattle yard. For purposes of this submittal, all lands within the indicated permit boundary will be considered affected lands, but only those locations between the existing access roads and which otherwise remain above the anticipated static water level of the resulting basins will be soiled and seeded to establish vegetation consistent with the approved reclamation plan. All other previously disturbed lands outside of the this area may be seeded to establish the desired vegetative cover where reaffected by planned activities, but in its previously disturbed state will not receive additional soil resources beyond what already remains, if any. Fortunately, the act of extraction serves to remove the most impacted portions of the location first, subsequently treating them with the approved seed mixture, thereby returning those lands to a stable configuration in a manner that might otherwise not occur had the location not been designated for extraction, but instead, left in its present blighted condition for an indeterminate number of years hence. Soil salvage will not commence until Tract C is ready for extraction (refer to Exhibit C-2: Extraction Plan) commencing with the removal of the surface layer of soil to a depth of 6.0± to 12.0± inches average, depending upon equipment and equipment operator • limitations. Additional depths of soil (to the extent it occurs) will be removed in like manner until commercially viable overburden and aggregate are reached, unless already exposed as in Tracts A and D. Soil salvage will be conducted primarily with scrapers. To minimize the undesirable effects of soil blowing and loss, and to avoid damage to the soil resource via compaction, soil will be stripped wherever possible when soil is moist, and not dry or wet. Any portion of the solum suitable for plant regrowth will be utilized to meet the minimum depth of soil replacement for reclamation, with the excess made commercially available for export from the property. Generally, soil will be retained in sufficient volume to reclaim all lands remaining between the anticipated static water level of the basins and existing access roads which surround them at any given point in time during resource recovery operations; as detailed in the following determinations: 102.87± acres — permit area - 75.02± acres — extraction limits extent = 27.85± acres — balance of lands outside of extraction but inside permit area. - 4.60± acres — existing internal access roads - 0.40± acres — existing above ground oil and gas facilities = 22.85± acres — balance of area requiring revegetation only • 75.02± acres — permit area - 62.81± acres — surface acres of basins — static water level Varra Companies, Inc. Western Sugar Reclamation Land Development Project 3 OMLR 112 Permit Application 2010 Exhibit I & J - Soils & Vegetation Information • = 12.21± acres — lacking soil and requiring resoiling and revegetation inside the extraction limits extent 12.21± acres requiring resoiling and revegetation = 9,849.4± cu.yds. soil needed for reclamation The sum of potential soil volume within the unaffected portions of Tracts C and D = 41.3± acres, or 33,315.3± cu.yds. of insitu soil. Assuming 33± percent of the areas lack adequate insitu depth due to past land uses or native soil conditions leaves an available insitu soil reserve of 22,321.25± cu.yds.; or more than twice the soil demand needed for reclamation. Once removed from its native location, soil retained for reclamation will be windrowed along the perimeter of the basin area of extraction or area to be resoiled, and seeded with the reclamation seed mixture specified under Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture. This will provide an opportunity to gauge the performance of the seed mixture while attempting to provide a stabilizing cover of vegetation over the stockpiles soil until it is ready for replacement on finished slopes and affected lands remaining above the anticipated static water level of the completed reservoir basins. Windrowed salvage soil stockpiles will be graded such that • the side slopes are 3H:1V or flatter. This will aid seeding and vegetation efforts while reducing the profile exposure of the stockpile to wind and water erosion, keeping the material stable until used for reclamation. Direct precipitation from short duration, high intensity rainstorm events, and wind, are the major threats to soil stability at this location. Although the location is nearly a table, and although the extraction will result in basins that cause water from direct precipitation to drain internally, additional measures will be taken to assure site stability and protection of off-site areas. The operator's stormwater management plan provides additional detailed information about maintaining on-site stability consistent with its pending Colorado Department of Health stormwater permit, and is available upon request by the Colorado Office of Mined Land Reclamation. The measures taken to stabilize the soil stockpiles, as described above, should be adequate for controlling erosion from wind and direct precipitation. Due to the flat topography of the Tracts, the interception of upland overland flows by local seep and irrigation ditches and access roads that intersect these tracts, there is little upland watershed that would impact these locations. The greater threat of erosion will be to resoiled slopes pending establishment of vegetation during reclamation. While some rilling can be anticipated on unprotected • areas following seed bed preparation and seeding. The conservation measures provided below should help to limit erosion potential that would threaten the revegetation efforts. Varra Companies, Inc. Western Sugar Reclamation Land Development Project 4 OMLR 112 Permit Application 2010 Exhibit I & J - Soils & Vegetation Information • Prior to resoiling, the foundation material that will underlie the soil will be sculpted to establish initial soil stabilization features, and left rough to aid in resoil adherence. Soil will be placed over a 12-18± inch minimum friable, or otherwise unconsolidated, subsoil. A 12-18± inch swale with slopes of 3H:1V or flatter will be placed above finished slopes where necessary to direct any upland surface flows around the finished slopes to an established stable drainage corridor. Resoiled areas will be allowed a minimum of three months to settle prior to seeding. Seeding will follow in the fall or spring as detailed under Exhibit E — Reclamation Plan. Resoiling will occur when soil moisture is adequate to prevent blowing, yet dry enough to prevent compaction. Part of the soil rebuilding process on the reconstituted soils will be in establishing structure to the soils to facilitate plant-soil-water relationships. Overly compacted soils will tend to limit soil structure development and create a poor seedbed for later establishment. Once applied to the surface, the new soils will be exposed to the raw forces of erosion until adequate vegetative cover and root mass develops. Erosion requires both detachment and transportation in order to occur. Running water, wind, and raindrop impact are the main forces of erosion acting upon the soil. The use of a sterile hybrid • live cover crop will aid in the stabilization of the soil by allowing a quick vegetative cover to become established in advance of the native grasses. The hybrid will also serve as an aid to reduce competition resulting from the establishment and growth of unwanted pioneer species (weeds) on disturbed ground. The attending reclamation seed mixture has a provision for the use of a sterile hybrid in lieu of mulch. Mulch, even when crimped with specialized equipment, is subject to being blown off the property, or reduced to an ineffective stubble. Often, it has been observed to intercept rainfall where it quickly evaporates from the stubble surface, limiting the benefits of light precipitation by preventing infiltration and percolation of moisture to the root zone. The hybrid on the other hand will establish quickly but since it is sterile will not continue to compete with the emerging native grasses. After two to three years it will begin to die out just as the native grasses emerge and improve their dominance over the revegetated areas. The applied organics will aid in the restructuring of the new soils by increasing the moisture and fertility holding capacity of the upper profile while simultaneously facilitating root development of the emerging grasses. As the roots of the emerging grasses develop and mature over time, the resulting root mass will serve to add to the base percent organic matter content of the new soils over time, thereby increasing the potential for long term survival and spread of the established grasses. Soil testing, • below, may occur on the new soils to better gauge the need or success of any applied organic soil amendments respective of the resulting vegetative cover. Varra Companies, Inc. Western Sugar Reclamation Land Development Project 5 OMLR 112 Permit Application 2010 Exhibit I & J Soils & Vegetation Information The addition of fertilizer may also aid in the establishment, growth and survival of the emerging grasses. Fertilizer may be applied to the seeded areas at rates determined from soil tests of the reapplied soils. To this end, soils may be sampled as needed. Sampling will utilize a hand auger and approved NRCS soil sample bags, and utilizing recommended procedures. Any soil testing will be conducted by the CSU Soil Laboratory in Ft. Collins, Colorado. The tests will be used to monitor soil quality and suitability of any amendments. WEED MANAGEMENT PLAN: Weed control at the site will utilize non-chemical means, unless, due to weed morphology, or other factors, circumstance require application of an approved herbicide. If chemical weed control is utilized, it will be conducted in compliance with manufacturer's recommendations and in conformance with applicable federal, state, or local laws. Where possible, pre-emergent weed control chemicals will be utilized. Chemical application will be conducted or supervised by a qualified operator. Weed control will focus upon prevention, principally through the establishment of a diverse stabilizing cover of grasses, as described earlier. Regardless of control • methodology, the intent of mechanical and chemical methods will be to prevent weed species from reproducing vegetatively, or by seed. In general, the idea is to aid the grasses in out competing weed species for plant available water and nutrients in the new soils, until such a time that the grasses are fully established over the applied areas, are dominant over the weeds, and capable of self regeneration. It should be understood that some weeds will remain. Total eradication of weeds is unlikely under the best circumstances, and is not a reasonable expectation or likely outcome. Since the list of noxious weed continues to grow; and considering the development of new treatments; this management plan is intended to retain the flexibility needed to meet future conditions and capabilities in the arena of weed management and control. The primary species to be identified, mapped (if found), and treated will include those species on the State of Colorado noxious weed list, as updated. Mapping and Identification: Field identification and location of targeted weed species is fundamental to determining the extent and character of weed infestation; and in the subsequent development of a treatment plan. Due to the complex nature of identification, assistance with identification and mapping will be sought from among Weld County Weed and Pest Division; Colorado State University Cooperative Extension Service; U.S. Natural Resources and Conservation Service; as well as on-line and internal resources. Van-a Companies, Inc. Western Sugar Reclamation Land Development Project 6 OMLR 112 Permit Application 2010 Exhibit I & J — Soils & Vegetation Information • Mapping will attempt to identify areas of infestation within the permit boundary, and vectors of infestation from inside or outside the permit boundary. Vectors are a consideration in prevention of future infestation, which may affect on-site behaviors, including method and means of access within permitted lands. An expectation that vectors from adjacent lands must be treated by adjacent landowners if treatment on permitted lands is to be fruitful is part of continuing treatment considerations. Treatment: Once the nature and extent of weeds have been mapped, and vectors identified; a course of treatment options will be considered in order of priority of economy and effectiveness. The overall object of weed management will be to control weeds by establishing a healthy competitive stand of vegetation that wins the competition for plant available water. This effort is linked to on-site soil management; including monitoring of soil fertility and percent organic matter on problem lands; relative to distribution and amount of field available moisture on affected areas. Chemical treatment of weeds will be the last option considered except where all other methods of competitive control fails; including mechanical cutting, tilling, or removal of noxious weeds. • In general, weeds will be cut before a seed head can develop. This will take priority over recently seeded areas expressing emergent grasses. Where mechanical means fail; chemical applications will follow recommendations from previously stated sources, and applied accordingly to prevent damage to grasses, aquatic species and wildlife. An example of Chemical treatment and primary noxious weeds can be found at the Colorado State University Extension Service website: http://www.ext.colostate.edu/. Where chemicals are not applied by the owner/operator of infested lands, a certified applicator will be retained. A file of all mapping and related log of treatment of identified areas will be maintained for inspection. • Varra Companies, Inc.

It also provides good forage for deer and pronghorn. The animal forage preference changes as the growing season progresses. Alkali sacaton, big bluestem switchgrass and prairie cordgrass are very palatable through the summer. These plants will benefit by deferment from grazing during late spring and summer. Vegetative palatability will influence proper use considerations. The season of use, weather, kind of grazing animal, past grazing use and the plant composition will directly influence animal preference and performance. b. Guide to Initial Stocking Rates (1) Stocking rates given below are based on continuous use for the entire growing season, and are intended only as an initial guide. Forage needs are calculated on the basis of 900 lbs of air-dry forage per animal unit month (AUM) . To maintain proper use and allow for forage that disappears through trampling, small herbivore use, weathering, etc. , 35 percent of the palatable forage produced is considered available for grazing by large herbivores. • Condition Percent Climax Class Vegetation AUM/Ac Ac/AUM excellent 76-100 .76-1.0 1.0-1.3 good 51- 75 .51-.75 1.4-1.9 fair 26- 50 .26-.50 2.0-3.9 poor 0- 25 0-.25 4.0-+ (2) Adjustments to the initial stocking rates should he made as needed to obtain proper use.

The basins may be lined or otherwise segregated from the area groundwater as an option to the approved permit, in order to liberate the water otherwise retained to supplement loss from evaporation in the unlined state. Since sufficient water resources exist, the option to line the resulting basins at an unspecified time during the life of the permit is retained under this • application and as part of the approved permit. GRADING: As stated in Exhibit D — Extraction Plan: A 1600± linear foot standard morphing extraction front is comprised of a 1.25H:1V face along an approximate 800-1200± linear foot advancing; wall with trailing side slopes up to 400 total linear feet combined along either side of the advancing wall where it serves to define the predetermined boundary of the extraction limits shown on Exhibit C-2: Extraction Plan Map. Concurrent grading follows immediately behind the trailing side slopes as they occur along the extraction limits. This morphing extraction front, with its advancing wall, trailing side slopes, and concurrent reclamation along the extraction limits is approximate for all active Tracts. The 1600± linear foot total extraction front is 'morphing' in that the • total linear feet of the front will not exceed 1600± linear feet, however, the advancing wall and side slopes may deviate from the 'standard' Varra Companies, Inc. Western Sugar Reclamation Land Development Project 3 OMLR 112 Permit Application 2010 Exhibit L — Reclamation Costs • lengths described above. For example: If the advancing wall is only 600± linear feet, trailing side slopes may have a combined length pending finished grading of up to 1,000± linear feet. Another example is if the advancing wall is 1,400± linear feet long, there is only 200± linear feet of trailing wall, and operations must be more Johnny on the spot in keeping up with concurrency in this configuration. So the 'morphing of the front generally affects the pace of concurrent reclamation of the trailing wall. Assuming a mean depth of advancing wall and sidewalls of 35.0± feet. 1600.00± lin.ft.

For now, an area estimate of 12.21± acres (Refer to Exhibit D) will be determined for resoiling expenses. At a depth of 0.5± feet, the total volume = 12.21± acres x 0.5± feet of soil replacement x 43,560.0± sq.ft./acre - 27 cu.ft./cu.yd. = 9849.40± cu.yds. total soil requirement.

Establishment of Vegetation over Affected Lands: • The demand establishment of vegetation over the affected lands will also diminish proportionately with the planned extraction of the Tracts. For now, the total exposure is estimated as indicated above to be 34.23± acres under a default: NOTE: The vegetation demand (and related costs) will decrease proportionately as extraction activities increase over each Tract of planned extraction. The cost for seed is shown on Exhibit L - Table L-1: Primary/Preferred Re-vegetation Seed Mixture and Costs and Exhibit L - Table L-2: Optional/Default Re-vegetation Seed Mixture and Costs. The mixture includes a substitute for mulch in the inclusion of a wheatgrass hybrid. The Division has historically agreed with and approved the inclusion of this hybrid as a substitute for mulch. These costs are as follows: $ 77.00± Preferred Seed Mix x 34.23± acres $ 2,635.71± Sub-Total Seed The cost for applying seed is based upon information derived in proximity to the Northern Colorado economy. Costs for tilling, fertilizing and seeding are based upon estimates from Longs Peak Equipment Co. These costs, including labor, are reflected as follows: $ 25.00± per acre Tilling • $ 20.00± per acre Fertilizing $ 20.00± per acre Seeding $ 65.00± per acre Total Application Cost per Acre.

On November 20, 2009 the Division of Reclamation, Mining and Safety (Division) increased the current Financial Warranty for this permit. The previous Financial Warranty calculation of$2,486,383.00 has been revised to reflect the changes to the Mining and Reclamation Plans submitted under Technical Revision -- 02. The Division's updated calculations(copy enclosed)estimate the cost to reclaim the site to be $286,979.00. This is an increase of$228,179.00 over the$58,800.00 currently held by the Division. • Per our agreement, the Division will grant an additional 30 days beyond the approval date of Technical Revision—02 to submit the increased Financial Warranty. The increase needs to be accepted prior to December 21, 2009. If you wish to submit a different type of Financial Warranty,you may find the appropriate forms on the Division's website at http://mining.state.co.us/Mineral%20Forrns.htm. if you have any questions.please contact me at(303)866-3567 x8116.

At the request of Brad Janos.the Division of Reclamation. Mining and Safety (Division) has revised the Financial Warranty calculation (copy enclosed) lilt the above referenced permit. The Division was able to reduce the costs for grading the pit walls in Tract A by changing the type of equipment used for grading. In addition. the cost for revegetation was reduced by eliminating • mulching from the estimate. The cost for revegatation could be further reduced by changing the seed mix. However,the proposed seed mix is ideal and will ensure the greatest chance of successfully revegetating the site. It is unlikely the other costs associated with reclamation can he reduced without changing the Reclamation Plan. Please revie%4 the enclosed figures as soon as possible and contact our office if any calculation errors arc noted. I( you have any questions, please contact me at (303) 866-3567 0116.

This project has been reviewed in accordance with Section 404 of the Clean Water Act under which the U-S. Army Corps of Engineers regulates the discharge of dredged and fill material,and any • excavation activity associated with a dredge and fill project in waters of the United States. Waters of the U.S. includes ephemeral, intermittent and perennial streams, their surface connected wetlands and adjacent wetlands,certain lakes, ponds,drainage ditches and irrigation ditches that have a nexus to interstate commerce. If any work associated with a project requires the placement of dredged or fill material,and any excavation associated with a dredged or fill project, either temporary or permanent, in the Cache la Poudre wetlands at the confluence of Ditch I (point 1 E)and the City of Greeley Orange Street Ditch (point 7), this office should be notified by a proponent of the project for Department of the Army permits,changes in permit requirements or jurisdictional determinations pursuant to Se tion 404 of the Clean Water Act. Reference is made to the November 13, 1986 Federal Register(Page 41217), Part 328 (a)Non- tidal drainage and irrigation ditches excavated on dry land, (h)artificially irrigated areas which would revert to upland if the irrigation ceased, (c)artificial lakes, ponds or irrigation ditches created by excavation and/or diking dry land to collect and retain water and which are used exclusively for such purposes as stock watering and irrigation,and(d)artificial reflecting or swimming pools or other small ornamental bodies of water created by excavating and/or diking dry land to retain water for primarily aesthetic reasons. The Corps of Engineers generally does not consider these types of aquatic resources waters of the U.S. except on a case-by-case basis. The wetlands of Ditch I (Al -- Cl)and wetlands of Ditch Areas 2A. 213 and 2C are considered non-tidal drainage and irrigation ditches constructed on dry land and are therefore not waters of the U.S. A Department of the Army permit will not be required for work in these wetlands. • • Upland Sites of Areas 3, 4 and 5 are non-aquatic upland areas populated with upland species. There are no Ordinary High Water Mark physical indicators or wetland characteristics associated with these sites. A DA Permit will not he required for work at this site We are interested in your thoughts and opinions concerning your experience with the Omaha District,Corps of Engineers Regulatory Program. We have placed an automated version of our Customer Service Survey form at: http:///perg.nwp.usace.anuy.mil/surv�.html. if there are any questions call Mr. Terry McKee of my office at 303-979-4120 and reference Corps File No.NWO-2010-62-DEN.

To assure the stability of any significant, valuable, and permanent man-made structures that may exist within 200 feet of planned extraction activity, a complete stability analysis was performed by CGRS, Ft. Collins, Colorado, follows. The report is based upon samples collected from the adjacent Durham Operation, located to the immediate east of the Western Sugar permit boundary, and are consistent with materials encountered at both locations. The report verifies that the maximum planned extraction slopes of 1.25H:1V will not pose a hazard to such structures. To the extent practical, operations will remain 125.0± feet or greater from residential structures, not otherwise owned or controlled by the operator. Concurrent grading and reclamation of completed areas of extraction will reduce extracted slopes to a minimum of 2H:1V to 3H:1V, or flatter, over a majority of the extraction area, in conformance with Rule 3.1.5(7). • • Varna Companies, Inc. Western Sugar Reclamation Land Development Project 2 OMLR 112 Permit Application 2010 • SLOPE STABILITY ANALYSIS VARRA GRAVEL OPERATION -DURHAM PIT GREELEY, COLORADO CGRS No. 1-135-9929 • Prepared by: Joby L. Adams CGRS, INC. 1301 Academy Court Fort Collins, Colorado 80524 800-288-2657 May 17, 2006 • • Introduction The following report presents the results of a slope stability analysis for the embankment that separates the Cache la Poudre River and Varra Companies (Varra) Durham pit gravel operation. This analysis was performed as part of the Flood Control Mitigation Plan required by Colorado Division of Minerals and Geology, in association with DMG Permit# M78-056. Background Information The Varra gravel quarry occupies a portion of the northeast corner of Section Nine and the central portion of the north-half of Section 10, Township 5 North, Range 67 west of the 6th Principal Meridian. The surrounding land use consists of agricultural, rural residential, commercial and open-cut gravel quarry operations. The permitted mine area occupies an estimated 230 acres with an approximate 100 acres of the operation dewatered and • excavated to bedrock. The water table at the site is located in unconsolidated alluvial deposits associated with the Cache la Poudre River. Soil conditions generally consist of varying thicknesses of top soil underlain by sand and gravel deposits, which in turn are underlain by Pierre Shale. Over the entire area the average saturated thickness of the sand and gravel deposits (prior to mining) is estimated at 26 feet. The natural hydraulic gradient as documented by past water resource investigation reports is on the order of 0.002 feet per foot, with the depth to water varying between 6 and 15 feet below ground surface. The natural groundwater flow direction is to the east-- northeast. Seasonal water table fluctuations of between one and three feet are common for this area; however, fluctuations of greater than ten feet have been documented during drought conditions (Schneider, 1983). The mine is dewatered by allowing groundwater to flow from the side walls of the excavation into ditches excavated into the shale bedrock at the toe of the excavation walls. The ditches are sloped so water drains to the north toward the Cache la Poudre River. The water is then pumped from the excavation into the river. A settling pond is located west of • • Slope Stability Analysis Varna Gravel Operation-Durham Pit Greeley,Colorado Page 2 the dewatering operation. The regional site location is depicted on Figure 1. Site conditions are depicted on Figure 2. Site Exploration and Laboratory Testing The bank between the Durham gravel operation and Poudre River is approximately 5100 feet in length. The unsaturated bank width varies between 40 feet in the western portion of the study area to in excess of 200 feet in the eastern portion of the study area. The river side bank height generally varies between 12 and 20 feet. The maximum vertical relief on the pit side of the bank is on the order of 50 feet, based in information provided by Anderson Consulting Engineers, Inc. The embankment was inspected on April 12, 2006, and no apparent signs of failure such as tension cracks or raveling were observed. • Soil conditions within the bank were evaluated by drilling six soil borings with a truck mounted hollow stem auger rig. The depth of the borings varied between 20 and 50 feet below grade. Representative soil samples were obtained by advancing a two-inch outside diameter split barrel sampler ahead of the auger bit. Details of each boring log are presented in Appendix A. Soil descriptions of cores obtained from within the embankment were recorded during drilling activities. In general, soil conditions consist of up to five feet of fill which is underlain by alluvial deposits of well graded sand and gravel. Bedrock, which consists of a dense, dark gray shale (Pierre Shale) underlies the sand and gravel deposits. The depth to water within the bank varied between 4 and 22 feet below grade. The boring locations are depicted on Figure 2. Overview of Stability Analyses Soil samples obtained from borings B-3, B-4, and B-5 were submitted to CTL Thompson • of Fort Collins, Colorado and tested to determine the following properties: water content; • Slope Stability Analysis Varra Gravel Operation-Durham Pit Greeley,Colorado Page 3 ➢dry density; >direct shear strength; >grain size distribution; >liquid limit; and ➢plasticity index. Field observations and gradation test results indicate the majority of the bank material is sand with gravel with a dry bulk density of 115 pounds per cubic foot. The internal angel of friction was calculated to be 49 degrees. The residual and peak cohesion was reported at 0 and 450 pounds per square foot. The moisture content varied between 7.5 and 11.5%. A cohesion of 0 was used in slope failure calculations. • The software program SLOPE/W and SEEP/W was used to estimate static bank failure safety factors. Mine pit and river flood conditions with rapid drawdown scenarios were simulated as well. These simulations were performed by CTL Thompson. The profile of section 43+40 as shown on Plate C15 (Attachment A) was used to predict safety factors. This section was chosen as it identifies the presence of a production gas transmission line and has substantial pit side bank height. The soil conditions were replicated to match the soil profile of soil boring B-6. Slope failure analyses were ran for the river and mine pit sides of the bank. The modified Janbu method was used as it provided more conservative safety factors. The river side stability results indicate factors of safety between 4.05 and 5.66. Simulations for static, pseudo static, mine pit flood and river rapid drawdown were performed. The same simulations were run for the pit side of the bank with calculated factors of safety varying between 1.99 and 2.35. The author used PCSTABL to evaluate slope stability at section 36+40. This section • appeared to have the steepest slope between the embankment and river of any cross sections presented by Anderson Consulting. Static conditions and river side and pit side • Slope Stability Analysis Varra Gravel Operation—Durham Pit Greeley,Colorado Page 4 100 year flood events were simulated. The soil characteristics as presented earlier were used in the analysis. Computer generated data sheets are presented in Attachment C. A review of Attachment C shows existing bank profiles are stable with calculated safety factors between 1.25 and 1.38 for mine and pit side flood conditions. Static condition simulations indicated a safety factor of 1.6. Discussion The field investigation indicates that the embankment separating the Varra Durham gravel operations and the Cache la Poudre River is primarily composed of sand and gravel. These deposits have a high internal friction angle. The slope of the embankment varies between less than 18 and 42 degrees, with the majority of the bank much less • than 30 degrees. The high friction angle and moderate bank slopes creates an inherently stable condition. The high permeability of the bank material reduces the potential for excessive pore pressures within the bank during rapid drawdown events. The bank slopes with out modifications are stable - even during flood event simulations. Data suggest that proposed bank modifications will not adversely affect bank stability. As the bank material is primarily dense to very dense sand and gravel it is our opinion that subsidence after a flood event will not occur to any significant degree. The fact that the bank has been in place on the order of decades without any history of failure supports the analysis presented herein. If any significant modifications to proposed or existing bank slopes occur this analysis should be considered invalid. • • Slope Stability Analysis Varra Gravel Operation—Durham Pit Greeley,Colorado Page 5 Comments The discussions and recommendations in this report represent our professional opinions.

Six borings were drilled at selected locations along the existing embankment alignment(Figure 1). Samples of the soils and bedrock penetrated by the borings and cuttings were classified (Figure 2 and Table I). In summary, there appear to be no stability problems with the section of levee you asked us to analyze (43+40). Variations in the subsoil conditions not indicated by our borings are possible.
