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 resoling 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 Varra 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). Van-a 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; (H) A description of the size and location of each area to be reclaimed during each phase; and (Hi) 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; (Hi) 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. Varra, hereby attest that the material to be utilized as inert fill in the area described as the Western Sugar Reclamation Land Development Project, is clean and inert as defined in Rule 1.1(20) of the Rules and Regulations.

(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. Varra 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.

Weld County, Colorado. 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 1 (point I E)and the City of Greeley Orange Street Ditch (point 7), this office should be notified by a proponent of the proiect for Department of the Army permits,changes in permit requirements or jurisdictional determinations pursuant to Section 404 of the (lean 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 arc 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 - CI)and wetlands of Ditch Areas 2A, 2B 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 arc no Ordinary High Water Mark physical indicators or wetland characteristics associated with these sites. A DA Permit will not be 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.

Sincerely, mothy T.C rey C Deny Re, latory S ffice tm Exhibit I & J — Soils & Vegetation Information 6.4.9 EXHIBIT I - Soils Information (1) In consultation with the Soil Conservation Service or other qualified person, the Operator/Applicant shall indicate on a map (in Exhibit C) or by a statement, the general type, thickness and distribution of soil over the affected land. 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. Varra 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: htto://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.

Overgrazing with cattle will result in big bluestem, switchgrass, prairie cordgrass, alkali sacaton, western wheatgrass and fourwing saltbush to decrease or disappear from the plant community. Inland saltgrass, sedges, rushes and several forbs and shrubs increase or invade the site. Continued overgrazing usually results in a sodbound stand of inland saltgrass on this site. page 3 #35 d. Basal area (the area of ground surface covered by perennial vegetation at ground level) is approximately 50 percent. e. Annual Production If the range is in excellent condition, the approximate total annual production (air-dry) is: Favorable Years 3500 pounds/Ac Normal Years 2800 pounds/Ac Unfavorable Years 1800 pounds/Ac Of this production, 5-10 percent will likely be unpalatable or out of reach of grazing animals. 4. Native Animal Community Associated with the Potential Plant Community: Deer and pronghorn are the principal big game herbivores. Other species that make use of this site include jackrabbit, other small mammals and rodents, ground nesting prairie birds, shore birds and waterfowl . 5. Soils The soils of this site are deep, somewhat poorly drained and occur on terraces and bottomlands. The soils formed in calcareous alluvium. The soil texture ranges from sandy loam to clay. Permeability is slow to moderate with a high to moderate available water capacity. Surface runoff is slow to moderate. Effective rooting depth of these soils is 60 inches more.

MAJOR OSES AMU INTERPRETATIONS FOR 1. Grazing a. This site provides excellent grazing for cattle and horses. It also provides good forage for deer and pronghorn. The animal forage preference changes as the growing season progresses. Alkali sacaton, big bluestem swltchgrass 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.

With specialized grazing systems, large livestock breeds, uncontrolled big game herbivores, inaccessibility, dormant season use, presence of introduced species, etc. , stocking rate adjustments will be required. page 6 #35 c.

Major Poisonous Plants to Livestock 3/ No poisonous plants to livestock are known at this time on this site. 1/ For additional information regarding poisoning by specific plants, see Colorado Range Technical Note. 2. Wood Products No known potential production. 3. Wildlife Value, This site has good potential for wildlife habitat especially since it usually occurs in association with other sites that provide good cover for wildlife. This site supports good populations of deer and jackrabbit. Due to run-in water from ajacent sites or the presence of a water table, nesting areas for ducks and geese are frequently available in depression areas. 4. Hydrological Interpretations Soils in this site are grouped into "B" and "C" hydrologic group, as outlined in the Soils of Colorado Loss Factors and Erodibility Hydrologic Group nqs handbook. Field investigations are needed to determine hydrologic cover conditions and hydrologic curve numbers. Refer to Peak Flows in Colorado handbook, and SCS National Engineering Handbook, Section 4, for hydrologic curve numbers and determining runoff quantities. S.

The information provided by the Operator/Applicant must be sufficient to calculate the cost of reclamation that would be incurred by the state. (2) The Office may request the Operator/Applicant to provide additional, reasonable data to substantiate said Operator/Applicant's estimate of the cost of reclamation for all Affected Lands. SUMMARY OVERVIEW: 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 - requirinq 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. Varra Companies, Inc. Western Sugar Reclamation Land Development Project I OMLR 112 Permit Application 2010 Exhibit L — Reclamation Costs The following assumptions of are based upon the pre-disturbed state of the application for purposes of determining estimated costs of reclamation and correlated financial warranty. Where appropriate, information is generalized and approximated from similar estimates determined by the Colorado Office of Mined Land Reclamation (OMLR), as indicated: Summary of Reclamation Costs: $ 3,836.45±Total Site Discharge —Avg. Life of the Mine $ 46,272.82±Total Grading per Extraction Front. $ 8,303.04±Total Re-soiling $ 7,290.93±Total Re-vegetation $ 65,703.24±Sub-Total $ 7,619.00±Possible Mobilization and Demobilization Costs (pending OMLR estimate — estimate ) $ 73,322.24±Sub-Total Direct Costs $ 17,842.97±Possible Indirect Costs Pending RMS Indirect Costs @ 24.335 % of Total Reclamation Costs $ 91,165.21±Grand Total — Financial Warranty Amount — Pending OMLR Review and estimates including estimated expenses for State of Colorado Mobilization and Demobilization and other `Indirect' cost determinations by the Office. RECLAMATION EXPOSURE: Based upon the Mining and Reclamation Plans of this application, the status and trend of activities and affected land; and related calculations to estimate reclamation liability, are determined as follows. Please Note: Due to the difficulty of calculating heavy equipment costs similar to the Division's software program, unit costs from previous and reasonably current Division estimates of like or similar kind have been utilized to create a reasonably close estimate. The per unit basis from Division records are shown along with other sources used or referenced to determine unit costs, at the back of this exhibit. Varra Companies, Inc. Western Sugar Reclamation Land Development Project 2 OMLR 112 Permit Application 2010 Exhibit L Reclamation Costs DEWATERING: Volumes per Tract: Tract A: 641,371.13 cu.yds. x 27 = 17,317,020.51 cu.ft. x 7.48 gal/cu.ft. = 129,531,313 gal. Tract B: 214,847.38 cu.yds. x 27 = 5,800,879.26 cu.ft. x 7.48 gal/cu.ft. = 43,590,577 gal. Tract C: 1,651,035.02 cu.yds. x 27 = 44,577,945.54 cu.ft. x 7.48 gal/tuft. = 333,443,033 gal. Tract D: 415,226.24 cu.yes. x 27 = 11,211,108.48 cu.ft. x 7.48 gal/cu.ft.= 83,859,091 dal. = 590,224,014 gal. Avg. = 590,224,014 gal. + 4 = 147,556,003.5 gal x $ 0.000026/gal. discharge (refer to Kurtz est. utilizing similar pump and rates.) Total Average Life of Mine Discharge Cost = $ 3,836.45 NOTE: The basins resulting from extraction will be reclaimed in an unlined state, since the operator retains sufficient water resources to do so. 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. H r 1.L 1 • II_ TC c \n = 927. i8 3H: 1V V S�� 1 . : 1 . 21I: '1V 2'_ I .

Varra Companies, Inc. Western Sugar Reclamation Land Development Project 4 OMLR 112 Permit Application 2010 Exhibit L — Reclamation Costs Soil Demand AND Re-soiling of Affected Lands (refer to Exhibit D): NOTE: The soil demand (and related costs) will decrease proportionately as extraction activities increase over each Tract of planned extraction. 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. The majority of soil placement can occur using the an average placement distance of 600 ft., or less along embankments, (utilizing the same assumptions utilized at either Kurtz or Heintzelman Projects as shown at the back of this exhibit). 9,849.4± cu.yds of soil demand x $ 0.843 per LCY. $ 8,303.04 to replace 0.5± feet of soil over the existing affected lands remaining above the anticipated final water level. 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. Varra Companies, Inc. Western Sugar Reclamation Land Development Project 5 OMLR 112 Permit Application 2010 Exhibit L — Reclamation Costs x 34.23± acres $ 2,224.95± Sub-Total —Application Costs $ 4,860.66± Sub-Total Re-vegetation (seed + application) Costs. Assume a 50± percent failure and add half the expense back into the total for reseeding, or: $ 2,430.33± Sub-Total Re-seeding costs $ 7,290.93± Total Re-vegetation Expense OTHER MISCELLANEOUS COSTS: Mobilization and demobilization costs are based upon the Division's estimates, which are pending. Demolition of Structures: None. Building Permits for structures will be obtain where required from the Weld County Building Department. Please Note: The per unit cost values derived from previous OMLR determinations for heavy equipment, as applied to this exhibit, are included at the back of this exhibit. Since there is no possibility of the applicant in fully reproducing the Division's methods, utilizing similarities from past OMLR calculations is the most viable and accurate means available for the applicant to derive reasonable estimates of per unit costs and should result in estimates very reliable with that of the Division.

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%20Forms.htm.

At the request of Brad Janes.the Division of Reclamation, Mining and Safety (Division)has revised the Financial Warranty calculation (copy enclosed) tier 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 revegctating the site. It is unlikely the other costs associated with reclamation can be reduced without changing the Reclamation Plan. Please review the enclosed figures as soon as possible and contact our office if any calculation errors arc noted. If you have any questions.please contact me at (303) 866-3567 x81 16.

Wadsworth Boulevard LITTLETON, COLORADO 80128-6901 January 15, 2010 Mr. Mark Bakeman, PII.D Ensight Technical Services, Inc. 1798 Hauck Street Erie,CO 80516 RE: Van-a Sugar Mill Site Proposed Gravel Mine Corps File No.NWO-2010-62-DEN Dear Mr. Bakeman: Reference is made to the above-mentioned project located in Sections 4 and 9,T5N, R65W, Weld County,Colorado. 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 1 (point 1E)and the City of Greeley Orange Street Ditch (point 7),this office should be notified by a proponent of the vroiect for Department of the Army permits,changes in permit requirements or jurisdictional detenninations pursuant to Section 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,(b)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 1 (Al -CI)and wetlands of Ditch Areas 2A,2B 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 I ligh Water Mark physical indicators or wetland characteristics associated with these sites. A DA Permit will not be 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.

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).

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 Varra 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 Van-a 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.

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. We believe this exploration was conducted with that level of skill and care ordinarily used by geotechnical engineers practicing in this area at this time. No warranty, express or implied, Is made.
