Notary Public My Commission expires: i(3o/aoio PROJECT DESCRIPTION for Parsons Mine The Parsons Mine site is located east of Windsor just south of County Road 64'/2 and on both sides of County Road 25. This 381+ acre site is owned, leased, or under contract for purchase by Lafarge. The other two land owners are Sally Parsons and Livingston Leigh Livestock of Weld County, LLC (please refer to the vicinity maps found on the attached mining and reclamation plan maps for the breakdown of ownership). A reclaimed gravel mine lies southeast of the site and rural residential/agricultural land uses surround the property on all other sides. Lafarge is proposing a sand and gravel extraction operation on the Parsons Mine property. The property will be mined in phases. Phase lA will be stripped of overburden to the sand and gravel layer below. A processing plant will then be set up at this elevation. Phase lA will also be the location of a fresh water pond and temporary silt storage pond until the permanent silt storage pond (in Phase 1B) is completed. Phase lA will actually be mined last as the processing plant will be used through the mining of Phase 5C. (See attached mapping for the location of each phase.) Phase I B will be the first Phase to be mined as it will be the location of the silt storage pond for the duration of the mine. Due to the location of an active Bald Eagle's nest within 1/2 mile of Phase 1B, mining will be restricted per discussions with the Colorado Division of Wildlife and US Fish and Wildlife. Phase 2 will then be mined followed by Phase 3 and so on until Phase 5C and then Lafarge will return to mine Phase 1A. Each Phase will be reclaimed following mining. The Plant Site area, which is located in Phase lA south of WCR 64%2 and east of WCR 25, contains the crushing, screening and washing equipment used for the processing of the raw materials. The processed materials will be stockpiled for delivery to off -site concrete and asphalt plants or for commercial and government projects. Berming and vegetation will be used to screen the plant site from view from County Road 64%2, County Road 25 and existing adjacent residences. Lafarge anticipates mining and reclaiming the site in approximately 20 years; however, the rate of mining and overall life of the mine is dependent upon demand and market conditions. Reclamation will be done concurrently, as well as subsequent to mining. This site will be mined and reclaimed to create a diverse, stable and sustainable environment. There are significant opportunities to enhance wildlife habitat and the natural aesthetics of the Cache la Poudre River riparian corridor. The reclamation plan is designed to accommodate these opportunities. Existing riparian vegetation and wetlands have been identified and will be monitored and protected throughout mining and reclamation. Mining activities will be set back an appropriate distance from all areas designated for preservation. A combination of open water ponds, wetlands and upland pastures will be created by the mining and reclamation process. Creative use of materials generated by mining and processing operations will enhance and compliment the existing riparian corridor. Silts will be used to form diverse silt basin wetlands. Excess overburden will be used to vary the shape and slopes of the finished unlined ponds. Native and adaptive plantings and ground covers will be used to restore and enhance all areas disturbed by mining activities. 3000' 6000' 2 s 3 LL 2 W / co o ; _ 32.. 33 -" O, INITY MAP -O 0 I R'.\4137_029\d Project No.: 133-4137.029.00 Qounty Rd 70 TETRA TECH www.tetratech.com 1900 S.

Dear Jared: • • Attached please find the DRMS 112 Reclamation Permit Application for the Parsons Mine. This permit is being submitted on behalf of Lafarge West, Inc. in care of Anne Johnson. As you are aware, a DRMS 112 Reclamation Permit Application for the Parsons Mine was originally submitted for review in December 2007. However, the application was withdrawn prior to expiration of the review period, thus necessitating submittal of a new application. Therefore, within this new application, we have addressed and incorporated responses to the Adequacy Review comments that we received regarding the original application. We anticipate that this effort will aid in your review. When we met with you in May 2009 regarding the original application and the Adequacy Review comments, there were a couple of issues that you asked us to clarify. We have done so in our application; however, we wanted to bring them to your attention here as well: 1. In Exhibit S, we have included a copy of the signed agreement between Kinder Morgan, Lafarge West, Inc. and Livingston Leigh Livestock of Weld County, LLC. This agreement shifts the location of the original easement that traverses the property along the west edge of County Road 25. The Kinder Morgan pipeline has not yet been constructed in this area. Therefore, we do not have a Structure Agreement with Kinder Morgan. 2. We are currently working to obtain Structure Agreements with all of the structure owners within 200 feet of the mining boundary. A summary of the status of Structure Agreements, as well as copies of all currently signed agreements and proof of notice for agreements, is included in Exhibit S. We will continue to forward copies of the remaining agreements as they are executed. In addition, an • • • Page 2 of 2 Parsons Mine October 16, 2009 updated Slope Stability Analysis for the project has been completed per your direction and is included with the application.

Parsons Mine DRMS 112 Reclamation Permit Application Page Cl of CI LARGE MAPS AVAILABLE FOR VIEWING AT THE CLERK TO THE BOARD'S OFFICE, IN THE PUBLIC REVIEW FILE. EXHIBIT D Mining Plan General The Parsons Mine property is located in the East 1/2 of the Southeast''/ of Section 25, Township 6 North, Range 67 West of the 6th PM; in the West '/2 of the Southwest % of Section 30, Township 6 North, Range 66 West of the 6th PM; in the Northeast''/ of Section 36, Township 6 North, Range 67 West of the 6`h PM; and in a portion of the Northwest ''4 of Section 31, Township 6 North, Range 66 West, of the 6th PM. The site is directly south of Weld County Road 64'/ and Weld County Road 25 bisects the property. The property contains a significant commercial deposit of sand and gravel located near the Cache La Poudre River. The permit boundary will encompass approximately 381 acres, with mining activities anticipated to disturb approximately 189 acres of the site. The remaining unmined acres will be used for overburden and topsoil stockpiles, offsets from existing structures, property lines and waterways, and internal road and conveyor access. Agricultural uses surround the property with the exception of some reclaimed gravel mining ponds that are southeast of the property. The site has been drilled during sampling episodes from March of 2002 to April of 2007, and testing has been performed to verify the sand and gravel deposits are commercially marketable. Based on test results, it is estimated that the overburden will amount to approximately 1,865,000 cubic yards. Overburden exists to an average depth of approximately 7 feet over the entire site. All overburden needed for the construction of the final reclamation slopes will remain on -site. The average depth of sand and gravel is 13 feet across the site and mining at the site is intended to progress down to bedrock. The groundwater level lies approximately 5 to 15 feet below natural ground level, on average. The deposit is therefore classified as a wet alluvial deposit. However, mining operations will be carried out following dewatering. The site is owned by Lafarge West Inc.; Livingston Leigh Livestock of Weld County, LLC; and Sally A. Parsons. Lafarge has a lease to mine the Livingston Leigh Livestock of Weld County, LLC property and both a lease to mine and an option to purchase Sally A. Parson's property. The site will be mined in five phases. These phases are neither representative of the maximum area of disturbance nor do they limit disturbance to a particular phase. The mineral rights in the portions of the site that fall in Section 36 are owned by the Colorado State Board of Land Commissioners. This affects portions of the land owned Sally A. Parsons and Livingston Leigh Livestock of Weld County, LLC. Parsons Mine DRMS 112 Reclamation Permit Application Page DI of D5 Methods of Mining The typical mining procedure for all phases will be as follows. Any areas slated for protection will be identified in the field to assure that mining operations will be set back as appropriate. Initially, the topsoil and overburden will be stripped with scrapers and stockpiled in the designated stockpile areas identified in Exhibit C. Overburden will also be used to construct berms and as fill in the reclamation slopes. Overburden and stockpiled topsoil will be seeded as appropriate to prevent erosion. Prior to mining, a dewatering trench will be constructed around the perimeter of each phase. A sump hole will be created at the lowest point of each dewatering trench. The sump holes and dewatering trenches will allow sediment to settle before the water is pumped to the Cache La Poudre River using a groundwater discharge pump in accordance with Colorado/NPDES discharge permit regulations. Pipes transporting the water from the mine will discharge the dewatering water directly into the river, the cottonwood gallery adjacent to the river, and/or the wetlands adjacent to active mining areas to maintain appropriate soil moisture during the growing season. Water may also be pumped into adjoining cells. The drainage swales will be designed when the Final Drainage Report is prepared for Weld County. Water may also be pumped into adjoining cells. When the alluvium is sufficiently dry, front-end loaders will excavate the material and deposit it on conveyors. The mining face will be nearly vertical to 0.5:1 slope. The conveyors will transport the material to be processed at the plant site which is located in the northeast corner of the Parsons Mine site. The plant site contains the crushing, screening, and washing equipment used for the processing of the raw materials. The processed materials will be transported to other sites to be used in concrete and asphalt plants and delivered offsite for commercial and government projects. All surface water within the mine areas will drain internally. The Preliminary Drainage Report prepared for Weld County (see Exhibit G, Attachment G-4) provides details of the conveyance of both off -site and on -site surface water through the site. Direct precipitation falling on a mine cell is collected in the perimeter dewatering trench and pumped out. There will not be any uncontrolled releases of surface water and sediment from mining areas. Storm water collected in the open mine will be managed in accordance with Colorado/NPDES discharge permit requirements. Sediment generated from localized storm water runoff and surface drainage will be managed according to the Stormwater Management Plan, enclosed in Exhibit G (Attachment G-3). Water rights at the site will be used for dust control operations along the roads, stockpiles and berms. The water balance discussed in Exhibit G estimates the gallons per week necessary to limit dust emissions. The water will be supplied using a 2,500 gallon water truck. No explosives are planned to be used. • • Overburden Topsoil and overburden will be stripped with scrapers or a dozer and placed separately in temporary stockpiles within the permit area limits. The topsoil will be segregated and stored separately from the overburden material as required by Rule 3.1.9(1). The topsoil will be placed in berms around the perimeter of the mine cells and will also serve as visual barriers where appropriate (see Exhibit C). The berms along the plant site and north perimeter will have an average height of 6 to 8 feet tall • Parsons Mine DRMS 112 Reclamation Permit Application Page D2 of DS • • • and are not expected to exceed 15 feet in height; they will have maximum 3:1 (horizontal:vertical) side slopes. The berms along the west side of County Road 25 will have an average height of 4 feet. The topsoil stockpiles will be protected from wind and water erosion by vegetative cover (see Seed Mix, Exhibit E). The stockpiles will be broadcast seeded and incorporated into the weed control program. Weed control consists of monthly inspections and, if necessary, chemical treatments in the applicable fall and spring seasons. Topsoil stockpiles that will be in place for more than 180 days will be vegetated depending on the seeding "window" parameters for dryland grass, which are typically between September and April. The overburden stockpiles will be continuously rotating. Initially, a portion of a phase will be stripped and the overburden stockpiled temporarily within the permit boundaries. Once the deposit has been mined from the stripped portion, the temporary stockpile will be removed and used for reclamation. The remaining portion of the cell will then be stripped and the overburden will be stockpiled on the mine floor or placed immediately in the reclamation slope. There will be no permanent stockpiles at this site; all extra overburden will be used to create undulating shorelines. Commodities to be Mined The primary commodity to be mined will be aggregate and a secondary commodity will be gold. Lafarge will supply local, county, and state governments, as well as private industry with aggregate from this facility. If gold is to be mined it will be used for commercial purposes. Offsets Lafarge will maintain mining offsets from sensitive areas designated for protection and all structures according to the Geotechnical Slope Analysis included in the Stability Exhibit. Setbacks were determined for each boundary and vary from 25 feet to 46 feet from structures. See Exhibit S and the Stability Exhibit for specifics. The Whitney Ditch, which traverses the north edge of the property boundary, will need to be relocated to accommodate additional right-of-way required for road improvements. Lafarge will relocate the ditch prior to the mining process and is working with the Ditch Company to obtain a formal agreement. There are some individual property lateral ditches will be eliminated. Some of the laterals are on the property owned by Lafarge so no consent agreement to mine through these laterals will be necessary. For the laterals on the property owned by Sally Parsons and Livingston Leigh Livestock of Weld County, the lease agreements that Lafarge has with both of these property owners address the right to mine through lateral ditches (please see lease agreements provided in Exhibit N). Roads and Conveyors Preparation for mining for each phase will include a 15' wide gravel access road around the perimeter of the cell. Any additional short-term haul access will be constructed with 6" of native sand and gravel from the floor of the mine. These gravel roads will be removed and reclaimed as mining and reclamation is completed for each phase. These areas have been included in the permitted acreage. The majority of the material will be transported from the mining face to the processing area via conveyors. There are two proposed conveyor crossings of County Road 25. The northern most crossing (between Phases IA and 2) will be utilized during the mining of Phase 2 and the southern- most crossing (between Phases 4A/4B and 3) will be utilized during the mining of Phases 4A Parsons Mine DRMS 112 Reclamation Permit Application Page D3 of D5 through 5C. Each conveyor crossing will be enclosed in 100 -foot spans, approximately 17 feet in height over the county roads. A conveyor will also cross the Cache La Poudre River. The conveyor • bridges are composed of steel; the footings are anchored in concrete. Details for the conveyor bridges can be found in Exhibit C. Upon completion of mining operations, the conveyors will be removed and all areas affected by the conveyors will be restored to their original condition. There is also the potential for a conveyor tunnel to be constructed under "O" Street if "O" Street is constructed prior to the completion of mining of Phase 5C. All existing on -site roads are shown on Exhibit C, Pre -Mining Plan. Any existing gravel access roads shared with ongoing oil and gas production or farming activities will remain in place once mining and reclamation are complete. The roads will be maintained by the operator to provide required access to the various activities on the property. Existing roads are typically 12' to 15' wide, gravel access lanes. Some of the roads may be relocated to accommodate mining activities. Relocated access lanes will be constructed with 6" of native sand and gravel from the floor of the mine and remain in place once mining and reclamation are complete. The main access to the site will be off of County Road 25 on the west side of Phase lA. There will be a paved loop lane into the site as shown and dimensioned on page 4 of Exhibit C. Mine Schedule The Parsons Mine operation will process approximately 750,000 - 1,000,000 tons of aggregate per year. At this rate, Lafarge anticipates mining and reclaiming the site in approximately 20 years; however, the rate of mining and overall life of the mine is dependent upon demand and market conditions. The mine phases are depicted in Exhibit C. The phases depicted in Exhibit C are used to indicate the direction of mining. These phases are neither representative of the maximum area of disturbance nor do they limit disturbance to a particular phase. Phase Overview Phase lA will be stripped of overburden to the sand and gravel layer below. The processing plant will be set up at this elevation. Phase 1 A will also be the location of the fresh water pond (approximately 5 acres) and temporary silt storage pond (approximately 2 acres) until the permanent silt storage ponds (in Phases 1B and 1C) are completed. Phase lA will actually be mined last as the processing plant will be used through the mining of Phase 5C. Phases 1B and 1C will be the first Phases to be mined as they will be the location of the silt storage ponds needed for the duration of the mine. Due to the location of an active Bald Eagle's nest within / mile of a portion of Phase 1C and within %I mile of a portion of Phase 1C and all of Phase 1B, mining will be restricted per discussions with the Colorado Division of Wildlife and US Fish and Wildlife, as outlined in Exhibit H in the section titled "General Effect on Wildlife Due to Mining Operations." Phase 2 will then be mined followed by Phase 3 and so on until Phase 5C and then Lafarge will return to mine Phase 1A. Each Phase will be reclaimed following mining.

State of Colorado, License # 7936 • • EXHIBIT E Reclamation Plan Design intent This site will be mined and reclaimed to create a diverse, stable and sustainable environment. There are significant opportunities to enhance wildlife habitat and the natural aesthetics of the Cache la Poudre River riparian corridor. The reclamation plan is designed to accommodate these opportunities. Existing riparian vegetation and wetlands have been identified and will be monitored and protected throughout mining and reclamation. Mining activities will be set back an appropriate distance from all areas designated for preservation. All mining activities will be set back a minimum of 200' from each side of the river. The only activities within the riparian corridor will include: controlled dewatering discharge consistent with a CDPHE permit; appropriately managed grazing of livestock; weed management; ongoing oil and gas production and maintenance activities; and a conveyor. The conveyor over the Cache la Poudre River will be installed in the location indicated on Exhibit C. Support structures for the conveyor will be placed outside the banks of the river and jurisdictional wetlands along the bank. The conveyor will include containment to assure that material does not spill into the river or adjacent wetlands during transport. Any additional conveyors that cross identified wetlands will be supported outside the delineated areas and include containment to limit spill into the wetlands. All other surface activities will take place outside the protected areas. Excavation associated with mining activities will be set back a minimum of 25' from existing wetlands. Wetlands will be clearly delineated with silt fencing and access from roads, stockpiles and maintenance activities will be set back a minimum of 10' from silt fencing. A combination of open water ponds, wetlands and upland pastures will be created by the mining and reclamation process. Creative use of materials generated by mining and processing operations will enhance and compliment the existing riparian corridor. Silts will be used to form diverse silt basin wetlands. Excess overburden will be used to vary the shape and slopes of the finished unlined ponds. Native and adaptive plantings and ground covers will be used to restore and enhance all areas disturbed by mining activities. This reclamation plan was developed based on: • A thorough evaluation of the environmental resources and existing conditions on and adjacent to the property; • The context of the property relative to existing and planned land uses in the area; • The volume, depth and configuration of the mineral resource; • The landowners' plans for the property; and • The rules and policies of Weld County, the Colorado Division of Minerals and Geology and other applicable local, State and Federal agencies. • Parsons Mine DRMS 112 Reclamation Permit Application Page El of E8 Key considerations include the following: • The Cache la Poudre riparian corridor passes through the property. In addition, all wetlands • on the site have been located and are identified on the pre -mining map. All efforts will be made to preserve and enhance the resources. • All areas designated for preservation will be clearly identified during the mining and reclamation activities for each phase. Isolated wetlands will be delineated with perimeter silt fencing. The 200' setback from the river will be clearly marked in the field and silt fencing will be installed as necessary to implement the CDPHE Storm Water Management Plan for the site. • Fourteen monitoring wells have been installed on the site to establish pre -mining groundwater levels. These wells and selected nearby private water wells will be used to monitor effects from mining and provide information for mitigation of potential impacts on groundwater levels and riparian vegetation, as necessary. Details of the monitoring and mitigation plans are provided in Exhibit G, Attachment G-1. • Maintenance activities on the site will also include a comprehensive Weed Management Plan (see attached) to limit the spread of invasive species into the riparian areas and wetlands. In addition, managed grazing will also help to control invasive species and promote regeneration of native cottonwoods and willows within the riparian corridor. Concurrent reclamation will also widen, buffer and enhance the riparian corridor as each phase is mined and reclaimed. • There is an existing bald eagle nest on an adjacent reclaimed gravel mine located south and east of the site. There are also raptor nests located on site along the Cache la Poudre River. • The sequence and timing of mining and reclamation activities will be managed to limit impacts to the eagles and other raptors, during the nesting season. • There is an opportunity to enhance wildlife habitat through the creation of a combination of open water ponds, silt basin wetlands, river corridor enhancement and shoreline plantings. • Silts generated by the mining process can be utilized to create diverse wetlands and add diversity to the habitat along this portion of the river corridor. • There are existing and planned oil and gas facilities on the site. Mining and reclamation activities will be managed to allow for continued operation and development of mineral resources. New drilling activities will be encouraged to utilize existing, disturbed areas at the maximum extent possible. • There is significant overburden on this site. Excess material will be used as much as possible to create wetland benches adjacent to the river corridor, vary the slope and configuration of the open water ponds, create shorelines that are more irregular and limit the surface area of the ponds to minimize evaporative losses from the groundwater. • Groundwater monitoring wells will be installed to establish pre -mining baseline water levels. Groundwater levels in the area of existing vegetation will be monitored. If levels drop below seasonal levels, dewatering water will be diverted to the areas to sustain existing vegetation to limits impacts during mining. • We anticipate a slight modification to the Phase 2 pond upon review by the landowner's landscape designer. Post -Mining Land Use The post -mining land use, as proposed in this Reclamation Plan, consists of wetlands, enhanced riparian vegetation, unlined ponds and reclaimed upland areas. Parsons Mine DRMS 112 Reclamation Permit Application Page E2 of E8 • • • • • All disturbed areas will be vegetated as appropriate with a native seed mix, as recommended by the Soil Conservation Service (recommended seed mixes below). These uses are compatible with the surrounding land uses and with the Weld County planning goals. Lafarge will concurrently reclaim mine walls where mining has been completed according to the phases outlined in the Mine Plan. Reclamation, including regrading and seeding, will be completed within two to five years following the completion of mining or filling operations for each phase. The mining and reclamation will leave no high walls on the property. No acid forming or toxic materials will be used or encountered in the mining. There will be no auger holes, adits, or shafts left on the site. Reclamation Measures — Material Handling Site reclamation measures are illustrated in Exhibit F. Reclamation of the site will include 8 unlined open water ponds (60.0 acres), approximately 48.4 acres of wetlands and enhanced riparian areas and approximately 187.3 acres of upland (approximately 78.1 of these acres are within the mining limits and the remaining 109.2 acres are other disturbed areas within the permit boundary). The ponds will be reclaimed as un-sealed groundwater ponds. All mine walls will be re -graded with overburden material. Slopes above the post -mine high water level will be 4H:1V and slopes below the post -mine high water level will not exceed 3H:1 V. Topsoil will be spread over the surface of the regraded slopes in all areas (except silt basin wetland) above the post -mining lake levels; all topsoil -covered surfaces will be revegetated with the appropriate seed mix. Scrapers will be used to place the backfilled overburden and topsoil. Using scrapers to layer the lifts at a maximum 3:1 slope ensures a stable configuration. Disturbed areas associated with site access and the conveyor will be scarified, covered with topsoil, and revegetated. Topsoil will be replaced, where required, in reclaimed areas at a depth of approximately six to twelve inches. Site grading will be performed to create stable topography and will be consistent with post -closure land uses. Reclamation quantities and costs are summarized in Exhibit L. Water Overburden and mine materials will be inert and impacts to local surface water or groundwater quality are not anticipated to occur as a result of mining activities. Lafarge West, Inc. will comply with all applicable Colorado water laws and all applicable Federal and State water quality laws and regulations and appropriate storm water management and erosion control to protect the river and existing riparian vegetation. Wildlife Presently, the area is used for farming and livestock grazing. There is significant habitat for many wildlife species along the river corridor. There is an existing bald eagle nest situated in an unstable dead cottonwood tree located on the south side of the river (on the adjacent property next to a reclaimed gravel pond). Phasing, configuration and timing of mining and reclamation activities Parsons Mine DRMS 112 Reclamation Permit Application Page E3 of E8 have been designed to limit impacts to eagle habitat based on the current location of the nest. Several protection and enhancement measures will be incorporated into the operation and reclamation plans to protect the current active bald eagle nest: • No mining activity will be conducted within'// mile of the nest from November 15 through July 31. • No mining activity will be conducted within '/4 mile of the nest throughout the year with the exception of development of an 18± acre wetland silt pond created just north of the river. The work to create this pond will be conducted over a 2 year period and will be limited to August 15 to October 15 to protect the occupied nest site. A wetland basin will be created through management of water and planting of native wetland plant species. The purpose of this silt basin is not only to dispose of smaller materials but also to develop a wetland adjacent to the river that will attract waterfowl and other wildlife species used as a food source for the eagles. • The river corridor will be protected from all mining activity by a 200 foot buffer. • Existing wetlands identified in 2007 will not be impacted by mining operations under the current Reclamation Plan. Any future changes to the Reclamation Plan that require an unavoidable impact to jurisdictional wetlands (such as a road crossing) would require coordination with the US Army Corp of Engineers and may involve obtaining the necessary permits under the Clean Water Act. • Coordination will be conducted annually with the Colorado Division of Wildlife to monitor the eagle nesting location and activity. Protection measures will be reviewed and coordinated with the Colorado Division of Wildlife should the eagles relocate their nest. • Coordination will be conducted annually with the Colorado Division of Wildlife to monitor the locations and activities of existing and new raptor nests. Additional wildlife enhancement measures include: • In consultation with the US Natural Resources Conservation Service (NRCS) or other qualified grazing specialists, develop and implement a suitable grazing plan for the riparian corridor that will promote restoration of a quality riparian pasture while discouraging colonization of the site by invasive plant species. This plan may involve limitations on the season of use and possibly a temporary rest. • A weed management program will be undertaken to control noxious and invasive plant species and to replace those species with native and naturalized vegetation. Canada thistle (Cirsium arvense) and leafy spurge (Euphorbia esula) will be treated by a combination of mowing at regular intervals and herbicides used at the appropriate times and applications levels. Please see the attached Weed Management Plan. • Riparian areas are one of the most important wildlife habitats in Eastern Colorado. This reclamation plan is being designed to maximize the upland riparian habitats by returning the mined areas to native upland habitats, native riparian habitats, and created wetlands. The plan will provide the most favorable habitats for wildlife through creation of edge by providing gentle slope transitions between riparian and wetland habitats and by limiting open water adjacent to the riparian zone. Restoring these areas from upland cultivated fields to wetlands and native wetland and riparian species will allow restoration of important floodplain functions. This plan is in harmony with the goals of the 1998 Greeley Open Space System Plan associated with wetlands, riparian areas and floodplains. Parsons Mine DRMS 112 Reclamation Permit Application Page E4 of E8 • • • • • • • Wetlands created may become part of a wetland bank for the property to offset wetland impacts on other LaFarge projects. • Wetlands created for nesting waterfowl will contain shallow open water (6-9") and gentle slopes (8:1). Shorelines will be irregular and gently sloping to maximize wetland growth and maintenance and provide suitable habitat for shorebirds and waterfowl. • Mining operations will be phased with reclamation occurring concurrently. However, some indigenous species may be temporarily displaced by the proposed mining activities. Please see Exhibit H for additional wildlife information. Topsoiling Topsoils in the proposed mine areas are predominantly Aquoll and Aquents, Colombo clay loam, Bankard sandy loam, Kim loam, Nunn clay loam, Otero sandy loam and Olney fine sandy loam. All suitable soil material will be salvaged for topsoil replacement. Topsoil will be replaced, where required, in reclaimed areas at a depth of approximately six to twelve inches. The topsoil will be segregated and stored separately from the overburden material as required by Rule 3.1.9O). The mine plan map depicts the location and configuration of the topsoil berms. The berms will be protected from wind and water erosion by vegetative cover if in place more than one year. The stockpiles will be broadcast seeded (please see the Seed Mix for Upland Areas) and will be incorporated into a weed control program. Weed control consists of monthly inspections and, if necessary, chemical treatments in the applicable fall and spring seasons. Soil amendments are not expected to be required due to the nature of the soils. However, topsoil samples will be subjected to agricultural testing prior to reclamation to assess fertilizer requirements. The Soil Conservation Services (SCS) will be contacted periodically throughout reclamation for soil tests. SCS soil fertilizer recommendations, if any, will be followed. Revegetation Following topsoil replacement, reseeding will be performed according to SCS recommended practices. Based on SCS guidance for other local projects having similar surficial soils, the following revegetation procedures are anticipated • Grass seed will typically be planted in unfrozen soil between October 1 and April 30. • Grass seed will be planted with a grass drill, or where necessary, with a broadcast seeder. • The proposed seed mix and application rates in pounds of pure live seed per acre are described on the following pages. • Weed control practices will be implemented as required. The above procedures may be modified as conditions dictate. If a significant invasion of noxious weeds occurs, the area will be mowed periodically for control. Weeds will be mowed before they go to seed during the first growing season. Mechanical control will be used as a first priority. Chemical methods will be used only if no other alternative produces acceptable results. Parsons Mine DRMS 112 Reclamation Permit Application Page ES of E8 In areas that are peripheral to the post -mining lake, marsh and aquatic plants are expected to establish themselves. The species of plants anticipated to occur naturally along the lake shoreline include cattails, willows, cottonwoods, and bulrushes. These plants should minimize shore erosion potential. The following are the proposed seed mixtures to be used on site where appropriate. However, availability may dictate the need for variety substitution.

Site evaluations will be conducted and management plans developed and implemented annually in an effort to maintain control of and/or eradicate noxious weeds, including Canada Thistle, Musk Thistle, Field Bindweed, Salt Cedar, Russian Olive and Leafy Spruge. Efforts are will also be focused on Kochia and Cheatgrass prior to revegetation of reclaimed areas. Areas outside of active mining areas will continue to be managed for agricultural production and grazing. Weed management will continue under the terms of the agricultural lease on the site. However, grazing will be managed and limited within the riparian corridor to allow native vegetation to reestablish. A revegetation plan to reestablish native grasses and enhance the riparian zone will also be initiated and include aggressive control of Kochia, Cheatgrass and other weeds, followed by grass drill seeding if necessary, to enhance reestablishment of native grasses.

Deeper bedrock aquifers that may underlie the site will be unaffected by the mining operation due to the shallow depth of excavations and low permeability strata beneath the shallow sand and gravel. A Groundwater Monitoring and Mitigation Plan is provided (Attachment G-1) as a guideline for monitoring and mitigation measures. Pertinent water features within and around the site are discussed and illustrated in the Groundwater Monitoring and Mitigation Plan and in Exhibit C. Mining will occur both north and south of the Cache la Poudre River. The various mine phase areas will be dewatered by the use of perimeter drains. All water collected as part of the dewatering will be discharged into drainage ditches then into the river. Upon completion of mining, there will be eight unlined ponds (approximately 60.0 acres) incorporated as part of the reclamation plan for recreation and wildlife habitat. Potential Water Resource Impacts The Parsons mining operation is projected to have minimal impacts on water resources in the area. Potential water resource impacts, in terms of drawdowns on groundwater levels, are addressed in the Groundwater Monitoring and Mitigation Plan (Attachment G-1) and Groundwater Modeling Evaluation (Attachment G-2). Due to the relatively thin gravel deposit, shallow excavation, phased operation, and natural and man-made hydrologic boundaries and barriers, a rather limited extent of drawdown due to the mine dewatering operation is projected. As addressed in Attachments G-1 and G-2, the site hydrogeology and groundwater modeling indicate that no existing permitted private wells would be significantly affected by the mine operation. Discharge Permits The proposed mine will be dewatered and operated as a dry mine. Alluvial groundwater from the dewatering will be discharged to the Cache la Poudre River, in accordance with CDPS permit conditions. The discharge rate will vary seasonally. The applicant will apply for a CDPS Industrial General Permit (for Sand and Gravel Mining and Processing General Permit). Surface Water and Stormwater Management The applicant will prepare a Sormwater management plan and obtain a permit for stormwater discharges from the CDPHE prior to mining activities. The Stormwater Management Plan is included as Attachment G-3. Site Drainage Hydrologic analyses of existing, mining, and reclamation conditions of the project are summarized in the Preliminary Drainage Report (Attachment G-4). Parsons Mine DRMS 112 Reclamation Permit Application Page GI of G3 Consumptive Water Use The Parsons Mine includes the following consumptive uses during the life of the mining operation. The consumptive uses include evaporative losses, water used for dust control, and water consumed in the mined material removed from the site. Evaporative Losses The NOAA Technical Report NWS 33, Evaporation Atlas for the Contiguous 48 United States (U.S. Department of Commerce) determined gross evaporation. For this location, the annual evaporation is 45 inches or 3.8 feet. Monthly evaporation percentages established by the State Engineer's Office (SEO) for elevations below 6,500 feet were used to calculate the monthly evaporation. Colorado Climate Summaries data from the Western Regional Climate Center Website (vcww.wrcc.dri.edu/cgi-bin/cliMAIN.pl?co3553) provided annual precipitation information at this site. The nearest station is the Greeley UNC Weather Station with a mean precipitation of approximately 14 inches for the years 1967 to 2009. Effective precipitation is 70 percent of total precipitation. Net evaporation is the difference between gross evaporation and effective precipitation. Net evaporation at the site is 2.93 feet. Water use at the Parsons Mine will include evaporation from exposed groundwater within the dewatering trench and the collection area during the mining period. In order to facilitate dry mining at the site, Lafarge will excavate a dewatering trench around the perimeter of the mining cells. The total length of the dewatering trench around the mining cells in Phases IA, 1B and 1C is approximately 13,700 feet. Assuming a width of 5 feet, the trench will expose an area of approximately 1.6 acres. A collection area at the discharge points from the dewatering trench will expose approximately 0.8 acre of water. Total exposed surface area at the Parsons Mine during mining will be approximately 2.4 acres. The total evaporative consumptive use during mining is 7 acre-feet. This is the volume which will be augmented during Phases 1A, 1B and IC. The exposed surface area will vary slightly during each phase of the Parsons Mine, but all evaporative consumptive use will be augmented during mining. Operational Losses The moisture content of the material removed from the site is four percent by weight as required in the State Engineer's Office (SEO) Guidelines. The production rate for the mining site is 750,000 tons of aggregate material per year. This results in an annual consumptive use of 22.1 acre-feet for water retained in product. Lafarge will apply water to haul roads and stockpiles for dust control. The estimated annual consumptive use for dust control is 2.0 acre-feet with a distribution throughout the year based on the same percentages as the production of the aggregate mined. The total annual operational consumptive use at the Parsons Mine is 24.1 acre-feet. Parsons Mine DRMS 112 Reclamation Permit Application Page G2 of G3 • • • Total Consumptive Use The total calculated consumptive use for the Parsons Mine is 28.5 acre-feet per year during mining. After reclamation, the planned long-term exposed surface area of the unlined lakes is approximately 60.0 acres. The long-term evaporative consumptive use is 177.2 acre-feet. Substitute Water Supply Plan and Gravel Well Permit Application Lafarge will submit a Substitute Water Supply Plan (SWSP) for the site to the SEO nine months to one year prior to the start of mining. Lafarge owns 12 Whitney Ditch shares and has a lease for five additional shares historically used on the property as a future source of augmentation water during mining. Since mining is several years away, Lafarge will keep the Whitney Ditch shares in irrigation to maintain the historic consumptive use of these water rights until they are needed for augmentation. Lafarge also owns other water rights such as 8.5 Box Elder Ditch shares and 550 Boyd and Freeman Ditch shares in this reach of the Poudre River Basin. These water rights are currently used to augment other active mining sites, but could also be used in the future to augment the Parsons Mine. Lafarge's water right portfolio in this reach of the Poudre River can augment the Parsons Mine during mining and after reclamation. The policy of the SEO is to provide a copy of the SWSP approval to the DRMS for the site when the review process is complete. Lafarge will also complete the required 600 foot well inspection with the water commissioner and submit the required gravel pit well permit application to the SEO. Lafarge will not expose groundwater at the Parsons Mine until both the SWSP and well permit are approved by the SEO. Long-term Augmentation A water court application for a long-term plan for augmentation will be filed three years prior to the completion of mining. The decreed plan for augmentation will replace all stream depletions from evaporation of the unlined lakes after reclamation.

This plan presents the methods and locations for monitoring of groundwater during gravel mining and site reclamation activities. Although adverse impacts to groundwater are not anticipated as a result of Lafarge's activities at the Parsons Mine, this plan also addresses how any adverse effects to groundwater would be mitigated, should they occur. Lafarge will submit a Temporary Substitute Water Supply Plan to the State Engineer's Office for approval. The temporary substitute supply plan is designed to protect senior vested water rights and mitigate potential depletions of flows in adjacent waterways. BACKGROUND The proposed Parsons Mine is located in Weld County, Colorado, near the Town of Windsor. The site occupies approximately 381 acres, which includes portions of Sections 30 and 31, Township 6 North, Range 66 West, and portions of Sections 25 and 36, Township 6 North, Range 67 west (Figure 1). The Cache la Poudre River flows through the southern portion of the site in a west to east direction. Several small ponds exist in the middle portion of the site. On the adjacent property to the east and southeast of the site, Hall Irwin Construction Company mines sand and gravel from their "Firestein Pit." Dewatering flows are discharged to the Cache la Poudre River. Several mine reclamation ponds also exist to the east and southeast of the site, with the largest being the Siebring Reservoir. These ponds help mitigate potential impacts to groundwater users to the east and southeast of their property. Sand and gravel will be extracted by the "dry" mining method. That is, mine cells will be dewatered using a perimeter drain to facilitate extraction of the gravel. The actual mining limits are anticipated to cover approximately 189 acres and the available gravel resource is anticipated to be mined for approximately 20 years; however, the rate of mining and overall life of the mine is dependent upon demand and market conditions. A processing plant will be built on -site to process resource materials from the mine. The reclamation plan for the mine includes several unlined ponds that will be sourced with groundwater inflow. Lafarge West Inc. — Parsons Mine 1 Groundwater Monitoring and Mitigation Plan The dewatering system would discharge to the Cache la Poudre River. Dewatering of the mine would lower the groundwater levels to a limited extent in the surrounding alluvial aquifer. Effects on groundwater levels are projected to be limited in extent due to natural and manmade hydrologic and hydrogeologic characteristics and boundaries, principally including the transmissive nature of the alluvial aquifer, the Cache la Poudre River system, and the mining operation and reclamation ponds on the adjacent property. Results of groundwater flow modeling (described below) indicate that the Parson Mine should not have any significant adverse effects on groundwater uses in the adjacent areas (Attachment G-2). Note that the groundwater modeling evaluation in Attachment G-2 was prepared as part of an earlier submittal to the DRMS that was subsequently withdrawn. It remains presented in its original form but additional interpretations of the modeling results, in response to questions and feedback from the DRMS, are included below as part of this document. Historic Use The site has been managed for agricultural uses (i.e., farming and grazing) and oil and gas production. There are irrigated alfalfa and corn fields and non -irrigated hay and wheat fields within the area of the site and surroundings. There is an adjacent active sand and gravel mine located to the east of the site that has been operated by Hall -Irwin Construction Company since 1996 (Firestein Pit; DMG Permit #M-1996-060). Sand and gravel have also been extracted southeast of the site, where reclamation has included several ponds/reservoirs. Monitoring Well Installation In April 2007, twelve (12) monitoring welts were installed around the perimeter of the site as shown in Figure 2. In September 2009 and in response to feedback from the DRMS, two additional monitoring wells (MW -13 and MW -14) were installed further enhance the ability to monitor potential effects on riparian vegetation along the Cache la Poudre River. The monitoring wells were installed outside the limits of contemplated mining, but within the proposed permit boundary, so that groundwater levels can be monitored during and after mining. The monitoring wells were constructed of 2 -inch Schedule 40 PVC casing and screen. Silica sand was placed from approximately two feet above the top of the screen to the bottom of the borehole (bedrock). Above the silica sand, a bentonite seal was placed in the borehole annulus to restrict infiltration of surface water. Each of the monitoring wells was finished at the surface with a locking, aboveground, steel protective casing set in concrete. Additional details of the monitoring well installations are provided in Table 1. Monitoring well permits from the Office of the State Engineer, Colorado Division of Water Resources, are included in this attachment along with the borehole logs and well completion information. The objectives of the well installation and monitoring program are to monitor the current groundwater conditions and to provide a basis for assessing potential effects to groundwater levels during and after the proposed mining. Some of the wells are located to also monitor Lafarge West Inc. — Parsons Mine 2 Groundwater Monitoring and Mitigation Plan • • • • • • for potential effects on cottonwood trees and other riparian vegetation along the Cache la Poudre River corridor. Through the well monitoring program, pre -mining groundwater elevations, flow patterns across the property, and seasonal fluctuations will be documented. Well Inventory A well inventory for the site and adjacent areas was conducted to identify wells near the project. The inventory included a review of the following records: a) Well records (Registered Wells) on file with the Colorado Department of Natural Resources, Office of the State Engineer (SEO); and b) Reported well records from Environmental Data Resources Inc. (EDR) — (EnviroGroup, 2007). Based on groundwater modeling results (Attachment G-2), the primary focus area for well records encompassed a radius of 0.5 miles (2,640 feet) from the property boundary. This radius was selected due the fact that simulated drawdowns from mine dewatering were less than about 1.5 feet outside this radius. The records search indicated that there are five permitted wells within 0.5 miles of the mine property (Table 2 and Figure 2). Lafarge has completed a survey of these wells and well owners to confirm the well locations and provide well owners the opportunity to have their well(s) included in the monitoring program. SEO requires a 600 -foot well spacing agreement statement from the well owners who have wells within 600 feet, at least six months prior to the commencement of mining of a relevant phase. The records search indicated only one permitted well within 600 feet of the proposed permit boundary. This well, identified below, is approximately 1000 feet from the closest proposed mine excavation. Permit: 51859 Owner: Ed On 826 9th Street Greeley, CO 80631 Use: Irrigation (currently not in use) Location: NW% SW' Sec 31, 6N 66W The Parsons Mine is not expected to have any significant effects on this well due to the following: a) Primary mining/dewatering activities near the well are located north of the Cache la Poudre River and the well is located south of the river. b) Mining activities south of Cache la Poudre River are principally isolated from this well by existing water storage reservoirs and the river itself due to its meander pattern. Lafarge West Inc. — Parsons Mine 3 Groundwater Monitoring and Mitigation Plan c) Due to recharges from the Cache la Poudre River and nearby reservoirs groundwater modeling indicates drawdowns at the well location would be less than 2 feet. Four residences were identified adjacent to the proposed Parsons Mine. However, these homes receive municipal drinking water from the North Weld County Water District and do not have wells registered for other uses. Modeling A numerical groundwater flow model was constructed of the site and surrounding areas to assess the potential impacts that the mine operation may have on groundwater levels (Attachment G-2). The U.S. Geological Survey's groundwater simulation code MODFLOW (McDonald and Harbaugh, 1988) was used for the modeling. The thickness of saturated alluvial sediments within the proposed mine site ranges from approximately 10 to 30 feet. The typical groundwater flow direction is to the east-southeast toward the Cache la Poudre River system. The groundwater flow directions and gradients can be expected to vary locally and seasonally due to changing irrigation patterns and other mining operations. The water table generally represents a subdued replica of the ground surface. The natural terrace that runs generally east -west through the northern portion of the site has a significant effect on groundwater flow gradients. Gradients are relatively low north of the crest of the terrace and in the river valley below the terrace, but are steep across the terrace, consistent with the ground surface. As shown in Table 2 and Figure 2, the records search indicated that five permitted wells are located within 0.5 miles of the mine property. Results of the groundwater flow model indicate that the Parsons mining operation would not significantly affect (i.e., create a drawdown of more than 2 feet) any of the identified well locations. Groundwater modeling indicates that several feet of drawdown could occur in the vicinity of the Jones Ditch. However, based on groundwater measurements in nearby monitoring well MW -11, groundwater levels are well below the ditch and it does not appear that the ditch is in direct contact with the groundwater table. If direct hydraulic connection does occur due to leakage, calculations indicate that ditch losses induced by dewatering may be in range of approximately 0.1 cfs. Mitigation of any such losses is addressed in the mitigation section below. The modeling also indicates that minor drawdowns could occur beneath adjacent agricultural lands. Due to the depths to water, the only areas of potential concern for sub - irrigated lands include those within the Cache la Poudre River floodplain or bottom lands. Typical depths to water below ground surface (bgs) in groundwater monitoring wells located adjacent to the river (MW -07, MW -08 and MW -10) range from approximately 5 to 7 feet. Typical depths to water bgs in wells located in the river bottom but at greater distance from the river (MW -09, MW -11, and MW -12 range from 4 to 9 feet. All farmlands located adjacent to the mine and within the river bottom lands are currently Lafarge West Inc. — Parsons Mine 4 Groundwater Monitoring and Mitigation Plan • • • • • • sprinkler or ditch irrigated. The only adjacent land where alfalfa crops are located is south of the mine property. Typical depths to water bgs in wells located adjacent to this area (MW -09 and MW -11) range from 7 to 9 feet. Due to the combination of depth to water and reliance on ditch irrigation, there appears to be little if any reliance on sub -irrigation. Lafarge believes that the proposed monitoring and mitigation plans will allow for identification and avoidance of impacts. MONITORING AND MANAGEMENT Groundwater Monitoring Fourteen monitoring wells were installed around the perimeter of the site as shown in Figure 2. Groundwater level monitoring began in April 2007. Monitoring was conducted bi-monthly for the first year. Since then, monitoring has been and will continue to be conducted on a quarterly basis to establish a site -wide baseline prior to mining. Table 3 and Figure 3 provide the existing groundwater level measurement data for the site monitoring wells, which likely captures the majority of the annual range in water level fluctuations. Once mining begins, monitoring will be conducted on a monthly to bi-monthly basis until a quasi -steady state condition is reached (during initial dewatering), and on a quarterly basis thereafter until one year after reclamation is complete. In addition, wells near river corridor areas adjacent to active mining phases will be monitored monthly during the growing season. Owners of wells within 0.5 miles have been contacted to obtain and document relevant well information and provide an opportunity for including their well(s) in the monitoring program. The following summarizes the results of the survey: Permit No. 114611 Permit No. 41189 Status Owner uses only for minimal livestock watering. Active mining by others directly adjacent to property without adverse effects, so owner not concerned or interested in having well monitored. Status Well used for periodic irrigation of 5 acres and trees. Owner requests monitoring, to be initiated when well is made accessible (pending). 4446 Well used for crop irrigation and located approx. 3/8 mile from proposed mine excavations. Owner requests inclusion in routine monitoring, which was initiated in October 2007 (Table 3). 10847 Same as above Lafarge West Inc. — Parsons Mine 5 Groundwater Monitoring and Mitigation Plan 51859 Owner states that well has not been in service for at least several years, but may be used in the future for irrigation. Owner agrees that well would not likely be impacted, but requests baseline monitoring. Monitoring was initiated in February 2008 (Table 3). Prior to mining, to establish a baseline, Lafarge will measure water levels in the applicable private wells bi-monthly to quarterly, or as access is provided. After mining begins, and as access is provided, Lafarge will attempt to measure water levels in the applicable wells quarterly, until one year after mining. Measurements may not be recorded for wells that are actively pumping for irrigation or that have been significantly affected by recent irrigation. Reporting Prior to mining, Lafarge will prepare and submit a report on baseline groundwater levels, utilizing data from the 14 existing monitoring wells and any other private wells included in the monitoring program. Thereafter, groundwater monitoring data will be submitted quarterly to the DRMS as well as with the annual progress report submitted to the DRMS and copied to the Weld County Department of Planning Services. If Lafarge receives a complaint from a well owner, Lafarge will submit their groundwater monitoring data to the DRMS in accordance with the mitigation plan below. A copy will also be provided to the Weld County Department of Planning Services. Wells Within 600 Feet As discussed above, there is one permitted irrigation well within 600 feet of the proposed permit boundary. Lafarge will attempt to obtain a 600 -foot well spacing agreement statement from the well owner at least six months prior to the commencement of the relevant mining phase. MITIGATION Monitoring data will be used to help identify potential changes in alluvial groundwater flows or elevations associated with mining and reclamation activities. Baseline data collected from the monitoring program will provide a range of water levels associated with pre -mining groundwater conditions. Experience at other sand and gravel mine sites in similar geologic settings, and baseline monitoring conducted to date, indicates that groundwater levels tend to fluctuate up to several feet per year, being highest in the summer and lowest in the winter and early spring. Due to normal seasonal fluctuations, Lafarge proposes to define the trigger point for potential mitigation procedures as 2 feet of drawdown relative to historic conditions. The amount of drawdown relative to the mitigation trigger point would be calculated and Lafarge West Inc. — Parsons Mine 6 Groundwater Monitoring and Mitigation Plan • • • • • • assessed relative to one standard deviation from the mean of measurements collected during the applicable season. In addition, wells in river corridor areas adjacent to active mining phases will be monitored monthly during the growing season. If monitoring indicates a drop of 1 foot below the historic baseline or if abnormal vegetation stress is otherwise noticed, dewatering flows or a portion thereof will be directed into established wetland areas and the riparian corridor to maintain the vegetation. In addition to the river corridor, a pond and associated wetlands are located just south of the Phase 2 mining area and immediately south of MW -4. MW -4 will be monitored monthly during Phase 2 mining operations. If monitoring indicates a drop of 1 foot below the historic baseline or if abnormal vegetation stress or pond levels are otherwise noticed, dewatering flows or a portion thereof will be directed into established wetland areas and/or the pond. Groundwater monitoring and modeling indicate that dewatering operations would not have a significant effect on flows in the Jones Ditch. However, Lafarge will enter into an agreement with the Jones Ditch Company that allows for dewatering water to be returned to the ditch to make up losses. This agreement will be in place prior to dewatering and mining south of the Cache la Poudre River. Groundwater modeling (Attachment G-2) indicates that there should be no significant effect on surrounding groundwater wells due to the Parsons mining operation. If Lafarge receives a complaint from a well owner, Lafarge will initiate an evaluation of the cause and notify the DRMS immediately (within 24 hours). After the DRMS has been notified, Lafarge will review the available data and information and submit a report to the DRMS within 30 days. To the extent practicable, the report will identify the extent of potential or actual impacts associated with the changes. The evaluation will include discussions with any well owner who has contacted Lafarge regarding a concern and review of available data from the well and vicinity to evaluate the cause of any changes (e.g., seasonal variations, climate, mining by Lafarge, mining by others, or other factors). Lafarge would also enlist the service of a contract professional hydrogeologic consultant to provide an opinion and meet with the Division to discuss the findings. If the claim cannot be resolved with this information, Lafarge would fund the service of a 3`d party consultant agreeable to the Division to render a separate opinion. If Lafarge's mining or reclamation activities are determined to be a significant contributing factor that has or may create adverse impacts, the mining -associated impacts will be addressed to the satisfaction of the DRMS. An initial temporary mitigation measure (for cases in which Lafarge's operation is a suspected cause) may entail providing an alternative water supply that meets the documented historic well production, or need, until further investigation can be conducted to determine if the well condition is due to Lafarge's mining operation. If, after review, the Lafarge West Inc. — Parsons Mine Groundwater Monitoring and Mitigation Plan 7 DRMS determines that the impact on a well, for which temporary mitigation has been initiated, is not a result of Lafarge's activities, or is not solely a result of Lafarge's activities, then Lafarge shall reduce or cease mitigation accordingly with the approval of the DRMS. Lafarge has no responsibility to provide mitigation for wells that are constructed after the permit is approved. Mitigation measures, divided into temporary and long term, may include, but are not limited to: Temporary: • Compensation for well owner to use their existing treated water system to replace the well production loss; • Provide a water tank and deliver water as necessary to meet documented historic well production or need; • Other means acceptable to both the well owner and Lafarge. Long -Term: • Cleaning a well to improve efficiency. • Providing an alternative source of water or purchasing additional water to support historic well use in terms of water quantity and quality. If needed, water quality parameters will be checked in affected wells to ensure alternative sources support the historic use. • Modifying a well to operate under lower groundwater conditions. This could include deepening existing wells or lowering the pumps. All work would be done at Lafarge's expense with the exception of replacing equipment that was nonfunctional prior to the impact. • If existing wells cannot be retrofitted or repaired, replacing the impacted well with a new well. • Providing groundwater injection/recharge to eliminate or reduce offsite impacts. If mining near the Cache la Poudre River results in stress to cottonwood or other riparian trees, Lafarge will mitigate the effect by using dewatering discharges or other water sources from decreed rights to irrigate the trees. Along with review of groundwater level monitoring data, trees in the vicinity of active mining and/or dewatering will be observed visually once a month to monitor for vegetative stress. Stress conditions will be gauged relative to other trees along the river in areas not subject to potential effects on groundwater levels due to mining. If a groundwater mitigation action is required, Lafarge will notify Weld County and the DRMS of the condition, action taken, and result.

The model was designed to evaluate the generalized groundwater flow regime in the unconfined alluvium and weathered bedrock aquifer and to assess potential effects of proposed dewatering and post -mining reclamation of the Parsons Mine on nearby shallow groundwater wells. The model was used to evaluate potential groundwater impacts by estimating the extent and magnitude of drawdown resulting from dewatering various parts of the site. The model was designed and simulations were conducted using the Visual MODFLOW program, version 4.1.0.145, developed by Waterloo Hydrologic Software, Inc. Visual MODFLOW is a graphical interface with pre- and post -processors for the MODFLOW groundwater flow model (McDonald & Harbaugh, 1988), which can be used to simulate groundwater flow in two or three dimensions. For this application, sufficient data do not exist to support development of a detailed and fully calibrated groundwater flow model. Therefore, average and representative groundwater conditions, hydrogeologic parameters, climatic conditions, and stratigraphy were estimated to perform simulations that are expected to represent the relative effect of the mine dewatering operation. Several sensitivity analyses were performed to evaluate the relative effect of certain parameter estimation variances. EnviroGroup Limited 1 2.0 Conceptual Site Model A conceptual site model was developed to provide a basis for simulating average groundwater flow conditions in the shallow unconfined aquifer in the floodplain of the Cache La Poudre River and claystone and sandstone in the adjacent bedrock terraces (Figure 1). Groundwater generally flows from west to east in alluvial sands, gravels and clay materials. Groundwater in weathered and unweathered claystone and sandstone terraces north and south of the floodplain is expected to flow generally southeast and northeast, respectively, and into the floodplain. The aquifer receives recharge from precipitation, leakance from irrigation ditches, and seepage from man-made water impoundments (gravel pit lakes, etc.). Alluvial groundwater that is not intercepted by existing gravel pit lakes generally flows toward or along the Cache La Poudre River, depending on groundwater elevations and river stage. Additional aquifer discharge occurs from irrigation wells and from groundwater pumping for other nearby mine dewatering operations. The unconfined shallow aquifer in the area consists of an upper layer of unconsolidated alluvium and a lower layer of weathered bedrock. The thickness of the alluvial sediments and the weathered bedrock surface were interpreted from analysis of 12 boreholes drilled on -site. Aquifer hydraulic parameters were estimated based on similar sediments observed in the Denver Basin and EnviroGroup staff experience with well tests and modeling of groundwater flow in Cache La Poudre and South Platte River alluvium. Groundwater elevations, flow directions, and gradients were assessed from data collected during on -site groundwater monitoring events, USGS topographic maps, and well records from the Colorado State Engineer's Office (SEC)). Data for the model design were obtained from site borehole lithologic data (Appendix A) and information on the regional groundwater flow system, and the inferences that can be drawn from the data. For example, groundwater elevations measured in on -site wells and estimated water levels based on topography and groundwater boundary conditions were used to develop a potentiometric surface and estimate the directions and gradients of groundwater flow. Water levels measured in on -site wells are presented in Appendix B, and discussed in Section 4.0. The model also incorporated anticipated recharge conditions and groundwater sinks and sources within the model domain (Section 3.0). Plans for dewatering the Parsons Mine involve placement and operation of perimeter drains to dewater the area of each mine phase. EnviroGroup Limited 2 • • • • • • In contrast to the valley -fill deposits in the mine area, the terrace deposits to the north and south are characterized as Pierre Shale and Pierre Shale transition materials (interbedded shale and hard ridge -forming sandstones) overlain by a thin layer of sand and red clay fan/pediment deposits (Hershey & Schneider, 1972; and Shelton & Rogers, 1987 - see excerpts in Appendix C). As a whole, strata of the Pierre Shale and transition zones exhibit low vertical hydraulic conductivities, and zones of higher horizontal permeability are limited. EnviroGroup Limited 3 3.0 Model Design and Parameters This section describes the model design and parameter selection. Model parameters were selected to reflect site -specific values where available, with additional data based on published information and experience with the shallow aquifers of the Denver Basin alluvial groundwater systems. The model was based on a 26,800 foot by 26,800 -foot lateral grid which was defined using 200- by 200 -foot grid cells in the Parsons mining area, expanded to 400- by 400 - foot grid cells in perimeter areas (Figure 2). The model was developed using one layer representing the unconsolidated alluvium, with the base of the layer defined as the top of claystone bedrock. The base elevation of the alluvial layer/top of bedrock was generated based on regional bedrock elevation data (Shelton, 1975) and from lithologic data obtained from 12 borings drilled on site. The alluvial aquifer thickness was based upon the site borings as well as well records from the SEO for outlying wells. Boundaries Conditions Model hydraulic boundaries (Figure 2) were assigned based on conditions observed at the site and surrounding areas, regional groundwater flow conditions from published maps, and hydrogeologic principles. Constant head boundaries were assigned along the east and west boundary of the model domain (Figure 2) to simulate inflow and outflow from the floodplain alluvium. Constant heads were also established at distance along the terraces north and south of the model mine site area to simulate southerly and northerly flow through the terraces into the floodplain sediments (limited due to low hydraulic conductivity). Constant heads were also assigned to simulate dewatering at two active gravel mine cells east of the Parsons site. Based on site observations and permitted mining plans, it was assumed, for modeling purposes, that dewatering of these areas will cease by the time dewatering and mining of the Parsons Mine site begins. Ditch and River Leakance Jones Ditch Leakance Surface flow in the Jones Ditch was modeled using the MODFLOW river package applied along its flow segment in the model domain (Figure 2). Note that contrary to EnviroGroup Limited 4 • • • • • • what is shown on the USGS base mapping, the Jones Ditch has been revised such that flow re-enters the Cache La Poudre River at Weld County Road (WCR) 25. A field inspection of the ditch (near WCR 25) and a comparison of ditch bottom and groundwater elevation data indicate that the ditch is approximately 5 feet above the groundwater elevation in the and will be loosing water to the shallow alluvial aquifer. Ditch bed conductance and inflow values were estimated from the approximate bottom width of the inlet (10 feet), the assumed bed thickness (0.5 foot), and a bed hydraulic conductivity (2x10-5 cm/sec). A hydraulic conductivity of 2x10-5 cm/sec was selected to represent the ditch bed because this would be reflective of a predominantly silty material or the low end of a clayey sand (McWhorter and Sunada, 1977; Davis & DeWeist, 1966), which likely provides a reasonable representation of the nature of the ditch bottom. Poudre River Leakance Shallow aquifer leakance to the Poudre River was modeled using the MODFLOW drain package applied along its flow segment in the model domain (Figure 2). A field inspection of the Poudre River along mine site was conducted at two locations where the river intersects 95th Avenue and where it intersects Colorado Highway 83. Site inspection and groundwater data (wells MW -7 though MW -12) indicate that the river stage is several feet below the adjacent groundwater elevations and the river gains water from the shallow alluvial aquifer. The drain package was used to simulate aquifer losses to the Poudre River because of model mathematical instability using the river boundary condition during simulated post - mine reclamation activities. The drain boundary is justified for this purpose as the Poudre River appears to always gain water from the aquifer and simulated groundwater elevations are above the drain elevations even during mine dewatering activities. Drain conductance values were initially set to approximately the same values as those estimated for river conductance and adjusted to approximate the flow out of the model that was obtained using the river package. Additional variations in the conductance were made during the groundwater elevation calibration process. The river (and subsequently drain) conductance values were based on an approximate river bottom width of 50 feet, an assumed bed thickness of 1.0 foot, and a bed hydraulic conductivity 1x10-5 to 2x10-5 centimeters/second (reflective of a predominantly silty material). EnviroGroup Limited 5 Hydraulic Conductivity and Storage Hydraulic conductivity (K) of the alluvial aquifer were estimated from published data of similar lithologies in the Denver Basin (USGS, 1989) and EnviroGroup's experience at other sites along the Colorado Front Range. The base -case average K for the alluvial floodplain was simulated at 5x10-2cm/sec. The alluvial K value was increased to 1x10-1 cm/sec in a paleochannel located north of the mine as estimated from a regional groundwater well yield map (Shelton, 1975). Based upon published information on the stratigraphic characteristics (Section 2.0), inflow from the claystone terraces to the north and south of the site was represented by assigning a hydraulic conductivity to the claystone/sandstone that was approximately two orders of magnitude lower than the alluvial floodplain sediments (5x104 cm/sec). The specific yield for the aquifer was simulated at 0.20. Recharge Aerial recharge was estimated based on the average annual precipitation of 13 inches per year in the site area (USGS, 1978). Model recharge was simulated at 10% of annual precipitation (1.3 inches/year) for alluvial deposits and at 1.0% of annual precipitation (0.13 inches/year) for the weathered claystone on the terraces north and south of the site. EnviroGroup Limited 6 • • • • • • 4.0 Model Calibration Model "calibration" runs were made to demonstrate that the model could produce heads and flow conditions that represent the conceptual groundwater flow model in the Parsons Mine area. The primary "calibration" checks were comparisons of the modeled heads, gradients, flow directions, and saturated thickness of the alluvial aquifer to those observed in the Parsons site area and represented in the conceptual model. The potentiometric surface used for model calibration was developed from water level data observed in on -site wells and heads estimated from ground surface elevations and depth to groundwater from SEO records on private wells in the region. The calibration simulations were run for a 20 year period, at which time head conditions had stabilized. Constant head boundaries, hydraulic conductivity, and drain conductance values were varied, as necessary, to approximate the calibration targets. Calibration targets and initial steady state model results are summarized in Appendix D. The initial heads generated from the calibrated MODFLOW model (Figure 3) represent the conceptual model. The model considers water level data observed in on -site wells and incorporates boundary conditions, aerial recharge, river leakance, drain flow, and dewatering of gravel mine areas downgradient of the Parsons Mine area. The heads simulated during model calibration (pre-dewatering of Parsons Mine) were used as the starting heads to simulate dewatering of the Parsons Mine, estimate the extent and magnitude of drawdown from dewatering, and to estimate the impacts of proposed post - mining reclamation activities. Although the model is idealized, consistent with the amount of available information, the simulated initial heads, site gradients, and groundwater flow directions match the known general flow patterns and elevations sufficiently for the purpose of the model. The simulated heads in mine -site monitoring wells were within about %2 to 21/2 feet of the "measured" heads at the piezometers with the exception of wells MW -4, MW -7, and MW -12. The simulated heads at these observation points were approximately four to five feet different than the "measured head", but it was felt that this was adequate given the idealized nature of the model, limited site and regional data, and the unknowns regarding how and where the hydraulic conductivity transitions between alluvial gravels and floodplain clays and silts. Additionally, unknown shallow perched zones of groundwater may exist at the site producing anomalous variations in the apparent groundwater EnviroGroup Limited 7 elevation data. Further, the model is likely conservative (on the high side) in terms of assessment of impacts because the difference in head elevations (higher initial model heads in MW -7 and MW -12) may produce greater model drawdown from the mine dewatering than occurs during actual mining activities. The modeled on -site groundwater gradient (0.007) and flow directions were essentially identical to site conditions assessed from borehole logs and well data. The modeled average saturated section was 11.6 feet compared to 9.5 as measured in on -site boreholes and wells. Because there are relatively little field data outside the proposed mine area upon which to base the model, assumptions were made that are expected to yield a conservative assessment of potential impacts. EnviroGroup Limited 8 • • • • • • 5.0 Model Simulation and Results Model Scenarios Mining and reclamation at the site is anticipated to occur for approximately 20 years; however, the rate of mining and overall life of the mine is dependent upon demand and market conditions. In order to assess potential magnitude and extent of groundwater drawdowns, simulations of the mining phase where performed for a period of 15 years, as follows: • Phase 1A: Years 1 —15 • Phases 1B and 1C: Years 4 — 7 • Phase 2: Years 8 — 11 • Phases 3 through 5: Years 12 —15 Given uncertainties in the timing of the various mine phases, sensitivity analyses included model runs assuming longer periods of mining to ensure that potential effects were fully assessed. Dewatering of the mine site was simulated by setting drain elevations near the base of the aquifer at cells along the perimeter of each mining phase identified in the mine plan (Exhibit D). The simulated drawdowns resulting from dewatering at the end of each of the above periods of mining were calculated by subtracting the heads generated at the end of the dewatering period from the initial heads simulated in the calibration phase (Figures 4, 5, 6, and 7). A post -mining model simulation was conducted to assess potential combined effects of reclamation activities of all mine cells (Mine Phases 1 - 5) on the shallow alluvial aquifer. Mined areas were modeled as either as a pond or as reclaimed (filled) with mine spoils according to the reclamation plan (Exhibit F). Excavations modeled as ponds were simulated with a hydraulic conductivity of 100 cm/sec to reflect the high transmissivity of the water body. Mined areas reclaimed with mine spoils were simulated with a hydraulic conductivity of lx104cm/sec to reflect the transmissivity of the silt and clay - rich material to be used to fill the former mine excavation(s). Post -mine simulations were conducted for a 10 -year period to simulate steady state conditions after reclamation activities are completed. The effects on groundwater elevations from the post -mining EnviroGroup Limited 9 phase were simulated by subtracting the heads generated at the end of a 10 -year "reclamation period" (i.e., no dewatering) from the initial heads simulated during the calibration phase. In addition, sensitivity analyses were conducted to assess the effect of varying selected input parameters and mine dewatering periods on simulated water levels and drawdowns. Results The results of the model simulations indicate that drawdowns produced from dewatering each of the five phases of the Parsons property is not likely to adversely affect the domestic irrigation wells located nearest to the Parsons Mine. The simulations indicate that a drawdown of one to two feet may occur in a limited area in the alluvial sediments within approximately one mile north of the mine site from dewatering (Figures 4 and 7). Model simulations of post -mining operations were evaluated by comparing water levels generated 10 years after mining reclamation activities were completed to the steady state initial water levels developed during the model calibrations process. The results of the simulations suggest that water levels outside the Parsons Mine area within approximately 700 feet of the north permit boundary may increase 1 to 2 feet due to post -mining reclamation activities. Simulated heads generally increased by 4 to 5 feet within areas where mine excavations are to be filled with overburden spoils. Sensitivity Analysis and Discussion A sensitivity analysis was conducted to assess how model output variables were affected by varying key input parameters. Aerial recharge and the mine dewatering period were varied, as follows, to observe the simulated effects on drawdowns induced by the Parsons Mine dewatering. • aerial recharge from precipitation was increased to 2.6 inches/year in the alluvial sediments for dewatering through year 15; and • the dewatering period was extended to 20 years. Increasing the recharge to 2.6 inches/year in the alluvial aquifer throughout the 15 year dewatering period did not result in any significant change in the heads or the magnitude of drawdown within the mine site from that observed with 1.3 inches/year of recharge. The increased recharge did significantly reduce the extent of smaller drawdowns (less EnviroGroup Limited 10 • • • • • • than 2 feet) at distance from the mine site. North of the mine site, the one foot drawdown contour line contracted approximately one mile to within approximately 1,300 feet of the north mine boundary (Figure 8). Extending the dewatering period to 20 years did not increase drawdown from that observed during the 15 year dewatering period, indicating that steady state conditions were achieved prior to the end of year 15. The generalized Parsons Mine groundwater model and simulation results rely on what are believed to be reasonable assumptions regarding hydrogeologic conditions in the modeled area. The groundwater users potentially affected by Parsons Mine dewatering and reclamation activities were identified from Colorado State Engineer's Office records and limited site reconnaissance (see Groundwater Monitoring and Mitigation Plan). If other permitted or unpermitted wells exist, potential effects should be specifically evaluated. EnviroGroup Limited 11 6.0 References Davis, S.N. and R.J.M. DeWiest, 1966. Hydrogeology.

These yields may vary substantially as a result of local changes in aquifer characteristics and the construction of the well. Although ground water is available throughout most of the study area, the yields will differ significantly depending on the geologic unit. The shallow alluvial (unconfined) aquifers, found along the major stream courses, yield the largest quantities of water (up to 2000 gpm), and the bed- rock (confined) aquifers yield smaller quantities (generally 0 to 15 gpm). The potential yield of a well tapping an unconfined aquifer depends on the hydraulic conductivity (the ability to transmit water) and the saturated thickness of the aquifer. As a result, the highest yields are obtained from the saturated, highly permeable, thick sand and gravel deposits in the major valley fills. Yields generally. decrease as the distance from the major streams increases. These lower yields are caused by a decrease in saturated thickness and, to a lesser degree, a decrease in hydraulic conductivity. Similarly, potential yields from bedrock aquifers depend on hydraulic conduc- tivity, thickness of aquifer, and hydraulic gradient. In general terms this means that a sandstone will be a better aquifer than a shale due to the greater capacity of the sandstone to transmit water. The recharge regime for unconfined and confined aquifers differs as do many of their other hydrologic characteristics. Unconfined aquifers are recharged vertically from the ground surface and are thus directly linked to surface hydrologic conditions. In the study area, the alluvial aquifers respond very quickly to seasonal variations of surface water and to precipitation, with the most important change apparently related to the irrigation season. For example, the water table rises markedly during the summer months as a result of seepage from irrigation ditches and of the irrigation of cropland. Bedrock aquifers obtain water in two ways. First, where the bedrock units crop out west of the study area, water percolates directly into the bedrock. Second, water percolates through the overlying material at-a-alow.,:rato.ovar !arge.arnas.. -Therefore, recharge . to confined aquifers occurs very slowly with no short-term, direct link to the surface water conditions.

Contour Interval 10 ft. Boundary of study area Ancient channels in bedrock surface DISCUSSION The Pleistocene and Recent geologic history of the Windsor study area has resulted in extensive, thick deposits of gravel, sand, and silt in the major stream valleys. This alluvial material conceals the config- uration of the underlying bedrock surface on which the streams once flowed. This map shows the configuration of the bedrock surface as it would look if the alluvial material were removed. The elevation contours show the old stream valleys that were cut into the bedrock during a period when erosion was dominant over deposition. The valley fills shown on the Bedrock Geology Map (Plate 6-A) were deposited after the erosional period during times when the stream regime was primarily depositional. In conjunction with the map showing Thickness of Unconsolidated Mate- rial (Plate 6-J), this map can be used to identify the trends of maximum thickness of alluvial deposits. This permits the identification of optimum sites for ground -water resources and for sand and gravel re- sources. Movement of water through the alluvium is, in part, related to the shape of the relatively impermeable, older bedrock surface over which the water flows. Maximum yields from water wells will be obtain- ed from that portion of a given aquifer with the greatest saturated thickness. Similarly, the quantity and quality of sand and gravel re- sources are closely related to old channels in the bedrock. in general then, the value of alluvial ground -water resources and sand and gravel resources will increase near the deeper channels in the bedrock surface.

Anne Johnson Land Manager Name (Printed) Title Signature Date Parsons Mine Storm Water Management Plan Page 3 of 19 SECTION 1 • Description of Industrial Activities This SWMP has been prepared for the Parsons Mine, which will produce aggregates for use at construction sites in the Greeley, Colorado vicinity. Figure 1 identifies the general location of the facility, as well as the nearest receiving waters. Construction activities that will be present at the site once active are as follows: • GRADING/MINING Site will be leveled and smoothed according to final project specifications using a road grader. Material may be excavated using earthmoving equipment and processed through various feeders, screens, and crushers. This may include right-of-ways, drainage ditches, and road sub -base areas of the project. ❑ QUARRYING Drilling and blasting is used to liberate virgin stone from its natural consolidated state. Haul trucks are typically used to take the material to the plant for processing. ■ STOCKPILING (Check if applicable) • OVERBURDEN AND TOP SOIL Stockpiles may occur in the form of earthen berms. • SAND AND GRAVEL Raw and/or processed aggregates are stockpiled for future use. • AGGREGATE MIX FOR CONCRETE PRODUCTION Aggregate can be stored in stockpiles, and loaded into a ground hopper as needed, and then conveyed to the plant. Material may also be loaded directly into a series of hoppers located above the plant that directly discharge into the plant. • AGGREGATE MIX FOR ASPHALT PRODUCTION Raw material can be stockpiles or put into storage bins. ❑ ASPHALT MILLING The existing roadway is milled, emptied into haul trucks and hauled off -site. ❑ ASPHALT PAVING Hot mix asphalt is transported to the project from a production plant located off -site. It is then placed, compacted and rolled according to project specifications. ❑ ASPHALT MANUFACTURING A hot -mix asphalt plant blends together aggregate and asphalt cement to produce a hot, homogeneous asphalt paving mixture, which is then hauled to off -site construction projects. The aggregate used can be a single material, such as a crusher run aggregate or Parsons Mine Storm Water Management Plan Page 4 of 19 • • • • • a pit run material, or it can be a combination of coarse and fine aggregates, with or without mineral filler. The binder material used is normally asphalt cement but can also be an asphalt emulsion or one of a variety of modified materials. Various additives, including liquid and powdered materials, can also be incorporated into the mixture. Activities at these sites may include the following: raw material unloading into stockpiles or storage tanks, raw material feed to plant, material batching, raw material storage area, recyclable asphalt disposal area, truck wash out, and water supply and settling lakes. ❑ READY MIXED CONCRETE, CENTRAL BATCHING These operations mix sand, gravel, cement, and water together to form ready mix concrete, which is then hauled to off -site construction projects. The raw materials are made up of sand, gravel, cement, water and additives. The sand and gravel is either stored in stockpiles located outside and fed into the plant via loaders and conveyors, or it is stored directly in a series of hoppers located directly above the central plant. The remainder of the raw materials is stored in tanks to protect them from exposure to moisture and temperature until they are pumped into the mixer. Once the raw materials are fed into the central mixer and combined to form Ready Mix concrete, the final product is placed within trucks and removed from the site. ❑ READY MIXED CONCRETE, DRY BATCHING These operations apportion out a mix of sand, gravel, cement, and water together, which is then mixed within the truck to form Ready Mixed concrete that is hauled to off -site construction projects. The raw materials are made up of sand, gravel, cement, water and additives. The sand and gravel is either stored in stockpiles located outside and fed into the plant via loaders and conveyors, or it is stored directly in a series of hoppers located directly above the central plant. The remainder of the raw materials is stored in tanks to protect them from exposure to moisture and temperature until they are pumped into the mixer. Dry batching then apportions out and dumps the raw materials into the concrete truck -mounted mixer where it is continually agitated and mixed to keep it from hardening before it arrives on the assigned job site. ■ EQUIPMENT FUELING Diesel and/or gasoline tanks may be located on site for fueling of equipment, or equipment may be wet -lined as needed. Off -site vendors refill tanks as needed. ❑ EQUIPMENT MAINTENANCE The site contains a shop area where necessary maintenance can be conducted for site equipment. Typical chemicals associated with maintenance, such as used oil, antifreeze, motor oil, hydraulic oil, brake fluid, etc, may be stored on site as needed. All chemicals are stored in such a manner as to prevent materials from mixing with stormwater or being accidentally discharged off site or to waters of the U.S. Parsons Mine Storm Water Management Plan Page 5 of 19 SECTION 2 • Site Map Enclosed is Figure 1: Site Vicinity Map, Figure 2: Site Overview Map; which indicates site - specific characteristics and BMPs implemented. The site has been determined to be within a single drainage area. The site comprises approximately 381 acres. Berms will be installed along property boundaries as necessary serve to prevent run-on from adjacent property. An existing drainage will be used for the discharge point, discharging into the Cache La Poudre River. Anticipated directions of stormwater flow, location of all surface water bodies, and outflow areas are indicated on Figures 1 and 2. The nearest receiving water that may receive storm water flows from the facility is the Cache La Poudre River (Figure 1). The following is a list of specific information to be included on the Site Map(s) as the facility becomes active: ✓ Site boundary ✓ Access & haul roads ✓ Stormwater outfalls and an outline of each drainage area for each outfall ✓ An estimate of the direction of flow ✓ Material handling areas ✓ Each structural control measure to help reduce pollutants in stormwater runoff ✓ Areas used for storage or disposal of overburden, materials, soils, or wastes ✓ Areas used for mineral milling & processing ✓ Springs, streams, wetlands and other surface waters ✓ Location of mine drainage or any other process water discharge points ✓ Boundary of tributary area that is subject to effluent limitations ✓ Date the map was prepared and subsequent revision date Parsons Mine Storm Water Management Plan Page 6 of 19 • • • • • SECTION 3 Stormwater Management Controls This section describes the development and implementation of stormwater management controls specifically designed for the Parsons facility including: SWMP Administration, identification of potential pollutant sources and Best Management Practices (BMPs), sampling information, preventative maintenance, good housekeeping techniques, Spill Prevention and Response Procedures, employee training, and identification of discharges other than stormwater.

Comprehensive inspections are completed as required based on activity at the site (please see Section 4 for additional details). Inspections will include at a minimum the following: • Integrity of diesel storage tank and secondary containment • Integrity of perimeter berms and truck wash out berms • Fuel spills in diesel fueling area, and material spills in the silo area and mixer area. • Open aggregate storage bins • Air and oil leaks on machinery and equipment • Belts, pulleys, rollers, and gates on plant equipment Cleaning and maintenance will be performed as needed and in response to inspection results. Records of these inspections are available through the plant manager or another member of the site SWMP Administration Team.

This will be accomplished through proper operation and maintenance of machinery and processing equipment. Careful material storage practices will be implemented. House keeping includes prevention and/or reduction of spilled aggregate and other particulate material. Principal good housekeeping procedures are as follows and will be implemented once the site is operational: • The material inventory is kept up to date, and all containers are labeled with the name and associated hazards. • Material safety data sheets (MSDS) are available on site to ensure that operation staff is aware of hazards and pollution potential. • Routine cleanup operations are ongoing and scheduled to ensure that the storage areas and maintenance areas are clean and orderly. • Good housekeeping, including cleanup procedures and disposal requirements, are incorporated into employee training. • Solid waste receptacles are available on site and are emptied regularly. Parsons Mine Storm Water Management Plan Page 14 of 19 • • • • • • Spill Prevention and Response Procedures The facility does not currently contain sufficient amounts of stored petroleum products as to require the development of a formal Spill Prevention, Control, and Countermeasure (SPCC) Plan. Secondary containment will be provided for any fuel or oil storage tanks stored on site. Removal of accumulated liquids from the containments is accomplished by use of absorbents, portable pump, or other technique, and waste material is properly disposed of. In the event that a spill occurs: o Do: • Shut off supply, stop leak (if possible) • Shut of ignition sources • Contain spill and/or dike ahead of spill • Notify Plant Manager. If the spill leaves the site or is greater than 25 gallons, the Plant Manager will notify Resource Management Group. • Protect adjacent people, property, surface waters, and equipment from contact with spill • Look to Material Safety Data Sheets (MSDS) for clean up guidance • Follow site SPCC plan • Place absorbents, dirt, or other solid materials in a non -leaking container and dispose of according to state and federal regulations o Don't: • Smoke • Risk personal injury • Wash down spill with water • Cover and not cleanup spill The majority of manufacturing process includes solid earthen materials with inert properties that would not impair surface or groundwater characteristics. The most common liquid not covered under the facility petroleum management plan would be process water associated with mine dewatering during mining. Parsons Mine Storm Water Management Plan Page 15 of 19 Employee Training Training of personnel will be conducted annually to educate employees, at all levels of responsibility, about the components and objectives of the storm water management plan for the site. The training scope will include the following topics: Spill Prevention Spill Response Good Housekeeping Techniques Materials Management Sediment & Erosion Prevention Definition of Process Water Best Management Practices in Place and Proper Maintenance While operations are conducted on site, it will be the responsibility of the site manager or operator in charge to train appropriate on -site personnel so that the goals of the SWMP are achieved. Various other types of environmental training will be conducted at different levels of the site management. Environmental Training topics are produced for `tailgate' meetings to discuss site - specific environmental management. Site managers participate in a number of internal and industry management meetings where environmental pollution control, regulations, and responsibilities are discussed. Records of personnel training conducted, including personnel in attendance, date of training, and scope of training will be available through the facility manager. Parsons Mine Storm Water Management Plan Page 16 of 19 • • • • • • Identification of Discharge other than Stormwater The site will be evaluated for the presence of non-stormwater discharges. Water associated with portable wash plants for processing aggregate and mine dewatering as necessary are the primary sources of non-stormwater on site. Mine dewatering will be monitored as outlined above to ensure no compliance with our permit restrictions. All other sources will be contained within the site and are not discharged with stormwater. Water stored and applied on site for dust abatement will be periodically utilized on the yard site and the access roads to suppress fugitive dust. Applied dust control is not applied in excess amounts that would result in an off -site discharge of liquids. Dust abatement is not necessary during precipitation events; therefore, no non -storm water at the site is intermingled with storm water runoff. Water and other liquids utilized in other peripheral uses and in the production of aggregate will be contained within the plant. Any mechanical failure with the potential to allow a surfaces release would be addressed through the site's spill response or emergency response protocols, free liquids would be isolated and adsorbed, and adsorbents properly disposed. Currently, no stormwater or commingled process water are in sufficient quantities to discharge from the site. Should subsequent water uses be initiated on site, these water sources will be identified in the table below: Types of Discharge No Discharge Permitted Process Water Unpermitted Exempt Control Measures Mine Dewatering X Equipment Wash Water X Dust Control (roads) X Irrigation return flows X Other Agricultural discharge X Fire Fighting discharges X Foundation Draining(SUMP) X Springs X Other Other Parsons Mine Storm Water Management Plan Page 17 of 19 SECTION 4 • Comprehensive Inspections Comprehensive inspections performed by qualified individuals, record keeping and internal reporting are essential activities under the SWMP and are outlined below. All records and reports will be maintained with the plan at the managing office. Once active, qualified personnel shall make a comprehensive inspection of the stormwater management system at least twice per year in the spring and fall for all active facilities. For idle sites where an employee is not stationed or does not routinely visit the site, inspections shall be conducted every two years. For inactive sites, inspections shall be conducted every three years. These comprehensive inspections must be documented and summarized in the Annual Report. Material handling areas, disturbed areas, areas used for material storage that are exposed to precipitation, and other potential sources of pollution identified in the SWMP in accordance with the permit shall be inspected for evidence of, or the potential for, pollutants entering the drainage system. Structural stormwater management measures, sediment and control measures, and other structural pollution prevention measures identified in the plan shall be observed to ensure that they are operating correctly. A visual inspection of equipment needed to implement the plan, such as spill response equipment, shall be made. Based on the results of the inspection, the description of potential pollutant sources and pollution prevention measures identified in the plan shall be revised as appropriate. Such revisions shall provide for implementation of any changes to the plan in a timely manner, but in no case more than 90 days after the inspection. A report summarizing the scope of the inspection, personnel making the inspection, the date(s) of the inspection, major observations relating to the implementation of the SWMP, and actions taken as described above shall be made and retained as part of the SWMP for at least three years. The report shall be signed by a Lafarge employee authorized to certify the plan.

The site is directly south of Weld County Road 64'/ and Weld County Road 25 bisects the property. The property contains a significant commercial deposit of sand and gravel located near the Cache La Poudre River. The majority of the site lies to the north of the Cache la Poudre River with a small portion to the south of the river in Section 36. There are several existing gravel mine operations in the project area. The Parsons Mine construction is granted by the Colorado Division of Reclamation, Mining and Safety (DRMS) permit (File Number M-2007-088). Purpose and Scope of Study This report has been prepared to document the results of a hydrologic analysis of existing, mining, and reclamation conditions of the project. Site Conditions Figure 1 is a vicinity map showing the site and surrounding area. The permit boundary will encompass approximately 381 acres, with mining activities anticipated to disturb approximately 203 acres of the site. The remaining unmined acres will be used for overburden and topsoil stockpiles, offsets from existing structures, property lines and waterways, and internal road and conveyor access. The irregularly shaped parcel is relatively flat and low lying in the greater floodplain of the Cache la Poudre River. The portion of the site to the south of the Cache la Poudre River is entirely within the jurisdictional 100 -year floodplain. Approximately half of the site to the north of the Cache la Poudre River is within the 100 -year floodplain. Agricultural uses surround the property with the exception of some reclaimed gravel mining ponds that are southeast of the property. The site has been drilled during sampling episodes from March of 2002 to April of 2007, and testing has been performed to verify the sand and gravel deposits are commercially marketable. Overburden exists to an average depth of approximately 7 feet over the entire site. All overburden needed for the construction of the final reclamation slopes will remain on -site. The average depth of sand and gravel is 13 feet across the site and mining at the site is intended to progress down to bedrock. The groundwater level lies approximately 5 to 15 feet below natural ground level, on average. The deposit is therefore classified as a wet alluvial deposit. However, mining operations will be carried out following dewatering. The site is owned by Lafarge West Inc.; Livingston Leigh Livestock of Weld County, LLC; and Sally A. Parsons. Lafarge has an option to purchase Sally A. Parsons' property and they have a lease to mine the Livingston Leigh Livestock of Weld County, LLC property. The mineral rights in the portions of the site that fall in Section 36 are owned by the Colorado State Board of Land Revised Preliminary Drainage Reportducx • • • • • • Commissioners. This affects portions of the land owned Sally A. Parsons and Livingston Leigh Livestock of Weld County, LLC. For the names of all property owners and those within 200 feet of the Parsons Mine property boundary see Appendix C. The site has historically been used as irrigated agricultural land and rangeland with approximately 98 percent pervious cover. On -site soils are 14 percent, 53 percent, 7 percent, and 26 percent Hydrologic Soil Groups A, B, C, and D, respectively according to the Soil Survey for Weld County, Colorado, Southern Part by the Soil Conservation Service (Appendix A). Portions of the site are within a Zone A floodplain according to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) Community -Panel No. 080266- 0608-D, dated September 27, 1991 (Appendix A). The Corps of Engineers completed a Flood Insurance Study in October 2003 for the Cache la Poudre River in the vicinity of the Parsons site. This study is currently under review by FEMA but has not yet become the effective study. For the purposes of this Flood Hazard Development Permit, the 100 -year floodplain and floodway boundaries of this pending study will be adopted as the best available information. The 100 -year floodplain, floodway, and Base Flood Elevations (BFEs) are shown on the Firmette presented in Appendix A. DRAINAGE BASIN AND SUBBASINS Major Basin Description The Parsons Mine site is located in the lower portion of the Bracewell Basin. The Bracewell Basin is an unstudied basin that is located east of the Law Basin and west of the Coal Bank Creek Basin. Subbasin Description The existing drainage conditions at the Parsons Mine site are presented in Figure 1 and Exhibit I. The existing historical drainage conditions were modeled as nine subbasins, H1 through H9. All the subbasins, with the exception of Subbasin H9, return storm water directly to the Cache la Poudre River once leaving the Parsons Mine site. Subbasin H9 passes storm water onto an adjacent property to the east. Portions of the site have historically been irrigated from the Whitney Ditch. All laterals on the site will be abandoned for both mining and reclamation phases of this project. Each existing drainage subbasin is described in more detail below. Subbasin H1 contains approximately 194 acres. The boundary extends from the north bank of the Cache la Poudre River in the southwest corner of the property north to the slough that runs through the property then northwestwards to the Whitney Ditch near its intersection with WCR 23 and from the intersection of the property with the Cache la Poudre River northwestwards to the Whitney Ditch near its intersection with WCR 23. The divide for drainage entering the slough provided the eastern boundary of this subbasin. The subbasin encompasses most of the Northwest One -Quarter of the Northeast One -Quarter of Section 36, and the Southeast One -Quarter of Section 25. The slope is generally between 0.5 percent and 2.0 percent with a subbasin average of 0.8 percent. -2- Reeked Preliminary Drainage Reporidocr. Storm water drains from northwest to southeast as overland flow and returns to the Cache la Poudre River as such. The subbasin has historically been used as cropland and contains two farmsteads. Subbasin H2 contains approximately 159 acres. The boundary begins at the culvert under WCR 25 and follows the slough along its southern extent to the boundary with Subbasin H1. The centerline of WCR 25 forms the eastern boundary and the Whitney Ditch forms the northern boundary. The subbasin is generally located in the Southeast One -Quarter of Section 25. The slope is generally between 0.5 percent and 4.0 percent with a subbasin average of 1.2 percent. Storm water drains from north to south and is collected in a slough on the southern subbasin boundary. The water is then conveyed to the Cache la Poudre River via a deep cut channel after passing through a 30 inch culvert under WCR 25. Subbasin H3 contains approximately 196 acres. The boundary extends from the south bank of the Cache la Poudre River in the southwest corner of the property south along an ancient meander of the Cache la Poudre River up a prominent ridge out of the floodplain, then west along the rim of the floodplain, turning back north into the floodplain to make its way back to the point where the property intersects the Cache la Poudre River. The subbasin is generally located in the East One - Half of the Southwest One -Quarter and the West One -Half of the Southeast One -Quarter of Section 36 and the Northwest One -Quarter of the Northeast On -Quarter of Section 1.

Subbasin H4 contains approximately 97 acres. The Cache la Poudre River bike trail forms the northern boundary of the subbasin except for a small area along WCR 25 where the basin crosses the bike trail to return to the Cache la Poudre River. From the bike trail, the basin follows the ancient meander bounding Subbasin H3 to the rim of the floodplain then turns east to the next prominent ridge where it courses northeast to WCR 25. The subbasin is generally located in the East One -Half of the Southeast One -Quarter of Section 36 and the Northeast One -Quarter of the Northeast One -Quarter of Section 1. The slope is generally between 0.5 percent and 20M percent with a subbasin average of 5.0 percent. Storm water drains from south to north and is collected in a series of gullies that open up to overland flow within the flood plain and returned to the Cache la Poudre River near the intersection of WCR 25 and the Cache la Poudre River. Subbasin H5 contains approximately 28 acres. The ancient river meander, the Cache la Poudre River, and the Cache la Poudre River bike trail form the boundaries of this subbasin. The subbasin is generally located in the South One -Half of the Northeast One -Quarter of Section 36. The slope is generally less than 0.1 percent with a subbasin average of 0.07 percent.

The slope is generally between 0.5 percent and 2.0 percent with a subbasin average of 1.7 percent. Storm water drains from northwest to southeast as overland flow and leaves the property as such. Drainage conditions during mining were considered for Phase 1 of the mining plan. Subsequent phases result in a similar condition for each phase. Water captured by the mining area will be pumped from the pit and discharged to the Whitney Ditch, one of the sloughs, or the Cache la Poudre River. At the close of each phase, reclamation of the completed mining phase will coincide with the mining of the subsequent phase. Phase 1 of the mining drainage conditions was modeled as 14 subbasins, P1-1 through P1-14, affecting the historical basins H2, H8, and H9, as shown on Exhibit 2. The remaining historical basins are unaffected by Phase 1 and will remain undisturbed. Each phase of the Parsons Mine site will be reclaimed immediately following the completion of the mining and will precede concurrent with mining operations in subsequent phases. The reclaimed drainage conditions were modeled as 18 subbasins, RB 1 through RB 18, as shown on Exhibit 3. All the basins return to the historical discharge points unless captured by open water ponds left by the reclamation process. -4- Revised Preliminary Drainage Rcp rt Aucx DESIGN CRITERIA Design Criteria and Constraints This report complies with technical criteria set forth in the Weld County Storm Design Criteria and the Urban Storm Drainage Criteria Manual, Volumes 1, 2, and 3, by the Urban Drainage and Hood Control District. As previously discussed, the Parsons Mine site lies within the Bracewell Basin and previous drainage studies and/or master plans have not been developed for this basin. The constraints related to mining and reclamation of the Parsons Mine site deal primarily with mining setbacks from property boundaries, wetlands, floodway boundaries, critical wildlife habitats, and existing gas/oil wells. During mining phases, temporary topsoil and overburden stockpiles will be constructed adjacent to the mined areas. These temporary stockpiles will be located outside of the floodway boundaries and oriented parallel to the direction of overbank flow. Upon completion of the reclamation phase of the project, all temporary stockpiles will be removed and final grading within the limits of the 100 -year floodplain will be to an elevation at or below pre -mining grades. Hydrologic Criteria The rational method has been used to estimate peak stormwater runoff for the 100 -year storm return period for subbasins with drainage areas of 160 acres or less. Runoff from subbasins with drainage areas greater than 160 acres was estimated using the Colorado Urban Hydrograph Procedure (CUHP). Supporting calculations are provided in Appendix B. Rainfall intensity -duration - frequency data is based on information provided in the City of Greeley Storm Drainage Design Criteria and Construction Specification Document. The 100 -year 1 -hour storm has a magnitude of 2.78 inches. Hydraulic Criteria During the mining phases of this project, temporary minor conveyance channels will be constructed to keep runoff from frequent storm events from entering the mining areas. In many places, these minor channels will be constructed alongside temporary topsoil and overburden stockpiles. The design of these temporary conveyance channels is presented in the Erosion Control Plan. Direct precipitation on the mined areas and runoff from major storm events will be captured in the mining areas. A dewatering trench and dewatering pump will be utilized to remove this captured runoff from the mining areas. If necessary, discharge permits will be obtained for each of these dewatering discharge points to allow discharge to the natural drainageways. The runoff from the site is dramatically reduced after reclamation is completed as compared with the existing conditions. The unlined reclaimed ponds will capture and attenuate surface runoff that historically flowed across the parcels. Existing natural drainageways will remain undisturbed. For reclamation, there are no proposed hydraulic components such as conveyance channels, rundown channels, culverts, grade control structures, or detention outlets. Each of the unlined ponds will be constructed with an outlet pipe installed to maintain the normal pool elevation. -5- Re wed Preliminary Drainage Rep rt then • • • • • • HYDROLOGIC RESULTS Existing Conditions The CUHP2005 computer program was used to model subbasins H1 and H3. These basins exceed the 160 -acre limitation of the rational method.

Subbasin H9 passes overland flow drainage to the neighboring property to the east. Phase 1 Mining Conditions Phase I of the mining plan represents the initial phase of five planned phases. The processing plant and the silt storage pond created in Phase I will remain for all later phases of mining. The use of temporary topsoil and overburden stockpiles around the perimeter of the mining area in Phase 1 is typical of the procedure used in later phases. Mined regions are reclaimed using the temporary topsoil and overburden stockpiles at the end of each phase. Conveyors across WCR 25 and the Cache la Poudre River will be used to move mined materials to the processing plant. Lafarge anticipates mining and reclaiming the site in approximately 20 years; however, the rate of mining and overall life of the mine is dependent upon demand and market conditions.

The reclamation plan is designed to accommodate these opportunities. Existing riparian vegetation and wetlands have been identified and will be monitored and protected through mining and reclamation. Mining activities will be set back an appropriate distance from all areas designated for preservation. A combination of open water ponds, wetlands, and upland pastures will be created by the mining and reclamation process. Creative use of materials generated by mining and processing operations will enhance and compliment the existing riparian corridor. Silts will be used to form diverse silt basin wetlands. Excess overburden will be used to vary the shape and slopes of the finished unlined ponds. Native and adaptive plantings and ground covers will be used to restore and enhance all areas disturbed by mining activities. Subbasin RB1 will be predominately grassland with an area of 134 acres.

Subbasin RB 17 returns to the Cache la Poudre River as overland flow at DP5. Elimination of Subbasin RB1S and Subbasin RB 16 runoff from contributing to DP5 is the major cause of the reduction from the historical peak flow rate of 20.2 cfs down to the reclaimed peak flow rate of 11.2 cfs.

Comparison of Existing, Mining, and Reclaimed Conditions Mining operations and site reclamation either will not change or will significantly reduce the drainage area and historical runoff leaving the site from each of the nine historical basins. At Design Point DP1 which includes Subbasins H1, RBI, and RB2, the peak flow rate reduces from the historical condition rate of 203.0 cfs to a reclaimed condition rate of 69.5 cfs. The drainage area contributing to flow leaving the site reduces from the historical condition of 194 acres to a reclaimed condition of 134 acres. The Phase 1 mining condition is the same as the historical condition. At Design Point DP2 which includes Subbasins 142, P1-14, RB3, and RB4, the peak flow rate reduces from the historical condition rate of 87.9 cfs to a reclaimed condition rate of 63.5 cfs. The drainage area contributing to flow leaving the site reduces from the historical condition of 159 acres to a reclaimed condition of 107 acres. The Phase 1 mining condition is the same as the historical condition. At Design Point DP3 which includes Subbasins H3, RB13, and RB14, the peak flow rate reduces from the historical condition rate of 283.0 cfs to a reclaimed condition rate of 125.8 cfs. The drainage area contributing to flow leaving the site reduces from the historical condition of 196 acres to a reclaimed condition of 131 acres. The Phase I mining condition is the same as the historical condition. At Design Point DP4 which includes Subbasins H4 and RB12, the peak flow rate for both reclaimed and Phase 1 mining conditions remains unchanged from the historical condition rate of 122.1 cfs. The drainage area contributing to flow leaving the site remains unchanged from the historical condition of 97 acres. At Design Point DP5 which includes Subbasins H5, RB1S, RB16, and RB17, the peak flow rate reduces from the historical condition rate of 20.2 cfs to a reclaimed condition rate of 11.2 cfs. The drainage area contributing to flow leaving the site reduces from the historical condition of 28 acres to a reclaimed condition of 12 acres. The Phase 1 mining condition is the same as the historical condition. At Design Point DP6 which includes Subbasins H6, RB9, RB9, RB 10, and RB18, the peak flow rate reduces from the historical condition rate of 24.7 cfs to a reclaimed condition rate of 9.7 cfs. The drainage area contributing to flow leaving the site reduces from the historical condition of 57 acres to a reclaimed condition of 30 acres. The Phase 1 mining condition is the same as the historical condition. At Design Point DP7 which includes Subbasins 147 and RB 11, the peak flow rate for both reclaimed and Phase 1 mining conditions remains unchanged from the historical condition rate of 11.4 cfs. The drainage area contributing to flow leaving the site remains unchanged from the historical condition of 22 acres. - 13 - Revised Preliminary Drainage Report cx • • • • At Design Point DP8 which includes Subbasins H8, P1-1, P1-3, P1-4, P1-5, P1-6, RB5, and RB6, the peak flow rate reduces from the historical condition rate of 55.4 cfs to a reclaimed condition of 22.8 cfs and a Phase 1 mining condition rate of 11.5 cfs. The drainage area contributing to flow leaving the site reduces from the historical condition of 85 acres to a reclaimed condition of 28 acres and a Phase 1 mining condition of 15 acres. At Design Point DP9 which includes Subbasins H9, P1-2, P1-7, P1-8, P1-9, P1-10, P1-11, P1-12, P1-13, and RB7, the peak flow rate reduces from the historical condition rate of 32.5 cfs to a Phase 1 mining condition rate of 30.lcfs. The peak flow rate for a reclaimed condition remains unchaged at 32.5 cfs. The drainage area contributing to flow leaving the site increases from the historical condition of 25 acres to a Phase 1 mining condition of 30 acres and returns to a reclaimed condition of 25 acres. RECLAIMED CONDITIONS Upon completion of the gravel mining, the site will be reclaimed as open water ponds, wetlands, and upland areas as shown in Exhibit 3. The designed spill elevation for each of the open water ponds is based on and groundwater model of the site. Each unlined pond has a minimum of approximately 2 feet of freeboard before overtopping could occur. The total effective detention volume of the reclaimed project is approximately 200 acre-feet. • • The surface hydrology associated with the reclaimed condition will not adversely impact the adjacent properties. Final grading will result in contours that either match or are below pre -mining contours. Surface runoff from the majority of the site will flow directly into the unlined ponds, wetlands, and upland areas. CONCLUSIONS Compliance with Standards All drainage analyses have been performed according to the Weld County Storm Drainage Criteria and the Urban Storm Drainage Criteria Manuals, Volumes 1, 2, and 3 by the Urban Drainage and Flood Control District. Drainage Concept The proposed Parsons Mine development will dramatically reduce the runoff from the site due to the capture of runoff within the mining area. Although only Phase 1 of the mining plan is presented in this Preliminary Drainage Report, each of the subsequent mining phases will significantly reduce surface runoff compared to existing conditions. Upon completion of each phase of the mining project, the screening/overburden stockpile berms will be removed and used for reclamation of the unlined open water ponds, wetlands, and upland areas. -14- Revised Preliminary Drainage Report dam For existing conditions, the sum of all drainage basin areas is 841 acres. Direct precipitation on the reclaimed unlined ponds and the sum of the subbasin areas that would be captured by the unlined ponds is 278 acres. The reclaimed site will reduce the contributing drainage area to approximately 67 percent of the historic area without increasing the imperviousness of the contributing drainage area. -15- Revised Preliminary Drainage Repon.docx • • • • • • REFERENCES Weld County Storm Drainage Criteria Weld County Public Works Department.

RUNOFF DRAINAGE CRITERIA MANUAL (V. 1) L= length of overland flow (500 ft maximum for non -urban land uses, 300 ft maximum for urban land uses) S = average basin slope (ft/ft) Equation RO-3 is adequate for distances up to 500 feet. Note that, in some urban watersheds, the overland flow time may be very small because flows quickly channelize. 2.4.2 Overland Travel Time For catchments with overland and channelized flow, the time of concentration needs to be considered in combination with the overland travel time, r,, which is calculated using the hydraulic properties of the swale, ditch, or channel. For preliminary work, the overland travel time, r„ can be estimated with the help of Figure RO-1 or the following equation (Guo 1999): v = C„ Sw,°s in which: V= velocity (ft/sec) C, = conveyance coefficient (from Table RO-2) S„ = watercourse slope (ft/ft) Table RO-2—Conveyance Coefficient, C, Type of Land Surface Conveyance Coefficient, C,. Heavy meadow 2.5 Tillage/field 5 Short pasture and lawns 7 Nearly bare ground 10 Grassed waterway 15 Paved areas and shallow paved swales 20 (RO-4) The time of concentration, rc, is then the sum of the initial flow time, r,, and the travel time, r,, as per Equation RO-2. 2.4.3 First Design Point Time of Concentration in Urban Catchments Using this procedure, the time of concentration at the first design point (i.e., initial flow time, r,) in an urbanized catchment should not exceed the time of concentration calculated using Equation RO-5.

This 381 acre parcel is located in the Bracewell, Colorado Quandrangle (Sections 30 and 31 of T6N, R66W and Sections 25 and 36 of T6N, R67W) on CR25 along the Cache La Poudre River (Attachment H-1). This site has historically been used for agriculture and livestock grazing. Livestock grazing (cattle) and hay production are currently the primary land uses on the property. The site encompasses several jurisdictional wetlands, a number of irrigation laterals, 2 ponds and approximately 6320 feet of the Cache La Poudre River. Significant Wildlife Resources The property is dominated by pasture grasses and agricultural fields with many areas populated by invasive and exotic plant species. Over one mile (6320') of the Cache La Poudre River flows through the southern portion of the property providing important wildlife habitat to many species especially raptors (birds of prey), song birds, and waterfowl. Red tailed hawks and great horned owls utilize the large cottonwood trees along the river corridor for nesting. Many species of waterfowl utilize the river for nesting, feeding and resting. Wood ducks utilize the cottonwood trees and some artificial nest boxes along the river for nesting. Eleven wetlands associated with the river channel, manmade ponds and irrigation ditches also provide important wildlife habitat especially wading and shorebirds. The presence of invasive and exotic plant species throughout the property and along the river channel somewhat diminishes the quality of habitat. According to Colorado Division of Wildlife's Natural Diversity Information Source for Weld County and range maps of wildlife species utilizing Colorado Division of Wildlife's GAP Analysis, potential large mammal species utilizing the property include: mule deer, Virginia opossum, American beaver, red fox, raccoon, mink, and white-tailed deer. Small mammals that likely inhabit the property include: Common muskrat, coyote, raccoon, red fox, big brown bat, hoary bat, red bat, silver -haired bat, Eastern and desert cottontail, white-tailed jackrabbit, black -tailed prairie dog, bushy -tailed woodrat, deer mouse, white-footed mouse, Hispid pocket mouse, house mouse, Northern grasshopper mouse, Ord's kangaroo rat, meadow vole, prairie vole, rock squirrel, thirteen - lined ground squirrel, Plains harvest mouse, Plains pocket gopher, Western harvest mouse, and stripped skunk. Waterfowl and wading birds species include: pied billed grebe, Western grebe, white -fronted goose, Canada Goose, wood duck, mallard, Northern pintail, blue -winged teal, cinnamon teal, common merganser, American white pelican, double -crested cormorant, black -crowned night heron, American coot, American avocet, common snipe, killdeer, and white-faced ibis. Raptors likely to inhabit the site include turkey vulture, bald eagle, Northern harrier, Swainson's hawk, red-tailed hawk, American kestrel, great -horned owl, and Western burrowing owl. Other likely bird species Parsons Mine DRMS 112 Reclamation Permit Application Page HI of H6 include mourning dove, ring-necked pheasant, common nighthawk, Northern rough -winged swallow, bank swallow, barn swallow, cliff swallow, belted kingfisher, downy woodpecker, Northern flicker, horned lark, blue jay, black -billed magpie, American crow, red -winged blackbird, yellow -headed blackbird, Brewer's sparrow, Cassin's sparrow, brown thrasher, California gull, black -capped chickadee, white breasted nuthatch, house wren, house finch, marsh wren, American robin, chimney swift, common grackle, Eastern kingbird, Western meadowlark, European starling, house sparrow, mourning dove and wild turkey. Amphibians likely to occur in the area include bullfrog, Great Plains toad, Plains spadefoot, tiger salamander, Western chorus frog, and Woodhouse's toad. Reptiles include: fence lizard, lesser earless lizard, many -lined skink, ornate box turtle, painted turtle, short -horned lizard, six -lined racerunner, snapping turtle, spiny softshell, variable skink, Western rattlesnake, Plains garter snake, and gopher snake. Wildlife species observed on the property include: black -tailed prairie dog, common muskrat, raccoon, red fox, eastern cottontail, fox squirrel, great horned owl, red-tailed hawk, bald eagle, great blue heron, Canada goose, mallard, wood duck, Northern pintail, blue -winged teal, white faced ibis, red -winged blackbird, belted kingfisher, killdeer, American robin, Northern flicker, blue jay, black - billed magpie, broad -tailed hummingbird, Common nighthawk, Eastern meadowlark, European starling, house wren, house finch, house sparrow, bank swallow, black -capped chickadee, Western meadowlark, mourning dove and killdeer. Seasonal Use of the Area Most of the wildlife species inhabiting the area are year round residents utilizing the entire corridor along the Poudre River. Migratory bird species utilize the river, irrigation ditches, ponds and the fields near these water features in both spring and fall. Presence and Estimated Population of Threatened or Endangered Species Sensitive species were assessed utilizing Colorado Division of Wildlife's Natural Diversity Information Source, Colorado Gap Analysis, and the Colorado Natural Heritage Program's Biodiversity Tracking and Conservation System (Attachment H-2). No federally listed threatened or endangered (T&E) species currently occurs on the property and no other sensitive species currently using the property were identified by the Colorado Natural Heritage Program's Biodiversity Tracking and Conservation System. T&E species that potentially occur or historically occurred near the site include: Preble's Meadow Jumping Mouse, Bald Eagle, whooping crane, burrowing owl, brassy minnow and Northern redbelly dace. A pair of bald eagles (Haliaeetus leucocephalus) nest on the adjacent property to the east and utilize the Parson's property for hunting and the river corridor for perching and roosting. The bald eagle was officially removed from the federal threatened list on July 9, 2007. Their populations will continue to be closely monitored and managed by the Colorado Division of Wildlife. The US Fish and Wildlife will also monitor their populations under their authority through the Bald and Golden Eagle Protection Act and Migratory Bird Treaty Act. The eagle's main source of food is the gravel pond on the adjacent property. They also utilize a large black -tailed prairie dog (Cynomys ludovicianus) colony to the southeast of the property. A prairie dog colony did exist on the Parsons Mine DRMS 112 Reclamation Permit Application Page H2 of H6 • • • • • • Parson's property approximate 1/2 mile to the west of the nest but is no longer occupied by prairie dogs. This pair of Bald eagles began to establish a nest in an abandoned heron nest adjacent to a newly created gravel pond in 2002 after the completion of the Hall -Irwin gravel operation. The eagles did not raise any eaglets until their second year, when they had one eaglet which was banded by the Colorado Division of Wildlife. In 2004, they successfully raised another eaglet. In September 2006, strong winds blew down the dead cottonwood tree on which they nested. The Colorado Division of Wildlife and volunteers built a new nest structure in a nearby live cottonwood tree. The eagles returned in 2007 but built a new nest on another dead tree near the gravel pond. The pair has fledged 3 eaglets this year in 2008 and one eaglet in 2009. Preble's meadow jumping mouse (Zapus hudsonius preblei), is a Federal and state threatened species that potentially inhabit the project area. Field assessment was made to determine whether suitable habitat exists according to requirements specified by US Fish & Wildlife Service (USFWS, 1998). Suitable habitat does not exist on the site for Preble's Meadow Jumping Mouse. Suitable Preble's habitat is described as "well -developed plains riparian vegetation with relatively undisturbed grassland and a water source in close proximity" (Armstrong, 1997). The Poudre River is deeply entrenched, heavily rip -rapped and sparsely vegetated. Disturbances have also been caused by farming practices and heavy grazing practices on this site. The shrub component that could provide cover and hibernaculum for PMJM is very sparse along the river. Due to channelization, past and current grazing management, the riparian zone is narrow and is dominated by upland grasses and a narrow band of Plains Cottonwood (Populus deltoides) and Russian Olive (Elaeagnus angustifolia). Presence/absence surveys have been conducted in the vicinity of this property with no captures of PMJM. (Colorado Natural Heritage Program, Biodiversity Tracking and Conservation System, 3/24/07, Attachment H-2). A disqualification report was submitted to the US Fish and Wildlife Service on May 11, 2007 (Attachment H-3). A clearance letter was received from the US Fish and Wildlife Service on June 21, 2007 concluding that "the proposed project on this site should not have direct adverse affects to Prebles' or Preble's habitat" (Attachment H-4). Burrowing owls (Athena cunicularia) are listed as a state threatened species and known to occur in the area. Burrowing owls are found primarily in eastern Colorado as a summer resident and as casual winter resident on the eastern plains. They are fairly common on the eastern plains. A survey was conducted on April 12, May 1 and June 1, 2007 to determine the presence of burrowing owl nests. No nests were found or burrowing owl observed. The brassy minnow (Hybognathus hankinsoni), listed as a state threatened species, potentially could be found in the Poudre River. However, no impacts to the Poudre are anticipated as a 200' buffer from mining activity will protect the river. Whooping cranes (Grus americana), a federal and state endangered species, are known as a casual migrants on the Eastern Plains and have been observed near the Parson's property historically. The Colorado Natural Heritage Program's Biodiversity Tracking and Conservation System identified one occurrence record near the property in 1982 east of Severence. Whooping cranes have not been observed in the area recently. One historic record occurs in the CNHP's system for the Northern redbelly dace (Phoxinus eos), a state endangered species. It was found approximately 1 mile downstream in 1914. Northern redbelly dace no longer inhabit the Cache La Poudre River. In Parsons Mine DBMS 112 Reclamation Permit Application Page H3 of 116 recent years only five specimens of the northern redbelly dace have been collected in Colorado. Propst (1980) collected two specimens from the Plum Creek drainage in the foothills south of Denver. Three others came from a pond adjacent to a Plum Creek tributary (Colorado Division of Wildlife, 2007). General Effect on Wildlife Due to Mining Operation The proposed project will not adversely affect wildlife or wetlands. Some of the resident wildlife species utilizing the pasture such as Canada geese, foxes, and rabbits may be temporarily displaced by proposed mining activity. The final reclamation will provide more diverse and higher quality habitat for wildlife currently utilizing the site and will likely draw many other species. Several protection measures will be incorporated into the operation plan to protect the active nesting bald eagles. No mining activity will be conducted within 1/2 mile of the nest from November 15 through July 31. No mining activity will be conducted within'/ mile of the nest throughout the year with the exception of development of a 12.7 acre wetland silt pond created just north of the river. The work for this pond will be conducted over a 2 year period and limited to August 15 to October 15. The river corridor will be protected from all mining activity by a 200 buffer. All existing wetlands identified in 2007 will not be impacted by mining operations. Colorado Division of Wildlife Recommendations Larry Rogstad, District Wildlife Manager for the Colorado Division of Wildlife was contacted on March 7, 2007. A site visit was conducted on June 1, 2007 and a coordination meeting was conducted on June 19, 2007. Mr. Rogstad provided recommendations to protect the eagles and to maximize wildlife habitat during the reclamation phase of the gravel mining operation. His response will be forwarded to the DRMS when we receive it. Literature Cited Armstrong, D.M., M.E., Bakeman, A.Deans, C.A., Meaney, and T.R. Ryan. 1997.

In response, I have searched our Biodiversity Tracking and Conservation System (BIOTICS) for natural heritage elements (occurrences of significant natural communities and rare, threatened or endangered plants and animals) documented from the vicinity of the area specified in your request, specifically within a two-mile radius of the proposed project site in Section 30, Township 6 North, Range 66 West in Weld County. The enclosed report describes natural heritage resources known from this area and gives location (by Township, Range, and Section), precision information, and the date of last observation of the element at that location. This report includes elements known to occur within the specified project site, as well as elements known from similar landscapes near the site. Please note that "precision" reflects the resolution of original data. For example, an herbarium record from "4 miles east of Colorado Springs" provides much less spatial information than a topographic map showing the exact location of the occurrence. "Precision" codes of Seconds, Minutes, and General are defined in the footer of the enclosed report. The report also outlines the status of known elements. We have included status according to Natural Heritage Program methodology and legal status under state and federal statutes. Natural Heritage ranks are standardized across the Heritage Program network, and are assigned for global and state levels of rarity. They range from "1" for critically imperiled or extremely rare elements, to "5" for those that are demonstrably secure. You may notice that some occurrences do not have sections listed. Those species have been designated as "sensitive" due to their rarity and threats by human activity. Peregrine falcons, for example, are susceptible to human breeders removing falcon eggs from their nests. For these species, CNHP does not normally provide location information beyond township and range. Please contact us should you require more detailed information for sensitive occurrences. There are no CNHP designated Potential Conservation Areas located within your project area. In order to successfully protect populations or occurrences, it is necessary to delineate conservation areas. These conservation areas focus on capturing the ecological processes that are necessary to support the continued existence of a particular element of natural heritage significance. Conservation areas may include a single occurrence of a rare element or a suite of rare elements or significant features. • The goal of the process is to identify a land area that can provide the habitat and ecological processes upon which a particular element or suite of elements depends for their continued existence. The best available knowledge of each species' life history is used in conjunction with information about topographic, geomorphic, and hydrologic features, vegetative cover, as well as current and potential land uses. The proposed boundary does not automatically exclude all activity. It is hypothesized that some activities will cause degradation to th element or the process on which they depend, while others will not. Consideration of specific activities or land use changes proposed within or adjacent to the preliminary conservation planning boundary should be carefully considered and evaluated for their consequences to the element on which the conservation unit is based. The Colorado Division of Wildlife has legal authority over wildlife in the state. CDOW would therefore be responsible for the evaluation of and final decisions regarding any potential effects a proposed project may have on wildlife. If you would like more specific information regarding these or other vertebrate species in the vicinity of the area of interest, please contact the Colorado Division of Wildlife. The information contained herein represents the results of a search of Colorado Natural Heritage Program's (CNHP) Biodiversity Tracking and Conservation System (BIOTICS), and can be used as notice to anticipate possible impacts or identify areas of interest. Care should be taken in interpreting these data. Sensitive elements are currently known from within the proposed project area, and additional, but undocumented, elements may also exist (see enclosed report). In addition to the data retrieved from our BIOTICS database we also searched the Colorado Division of Wildlife Bald Eagle (Haliaeetus leucocephalus) dataset and located an known active nest site near the intersection of CR 25 and CR 62 at the Cache la Poudre River in Section 31, Township 6 North, Range 66 West (see included metadata for the CDOW dataset). Please note that the absence of data for a particular area, species, or habitat does not necessarily mean that these natural heritage resources do not occur on or adjacent to the project site, rather that our files do not currently contain information to document their presence. CNHP information should not replace field studies necessary for more localized planning efforts, especially if impacts to wildlife habitat are possible. Although every attempt is made to provide the most current and precise information possible, please be aware that some of our sources provide a higher level of accuracy than others, and some interpretation may be required.

May 11, 2007 aPeter Plage US Fish & Wildlife Service, Colorado State Office PO Box 23486, Denver Federal Center Denver, CO 80225 Dear Peter: At the request of Eric Reckintine, LaFarge - North America, (1800 N. Taft Hill Rd, Fort Collins, CO 80521), I was asked to review habitat suitability for Preble's Meadow Jumping Mouse (Zapus hudsonius preblei) on a proposed gravel mining operation near Greeley, Colorado. The owners plan to apply for a Colorado Division of Minerals and Geology 112 mining permit on this 360 acre parcel at the intersection of CR 64.5 and CR 25 in Weld County (Attachment 1 - Project Vicinity Map). This survey was conducted on May 1, 2007 on the Parsons property (Sec 30,31 of T6N, R66W, Sec 25,36 of T6N, R67W, Bracewell, Colorado Quandrangle) along the Poudre River from 4718 to 4716 feet in elevation. UTM coordinates range from 13T 0513410E, 4477030N on the upper end of the river to 0514680E, 4477320N on the lower end of the river. This survey covers the area outlined in the attached map (Attachment 2 - Project Map). This site is within potential occupied range: (USF&WS, Interim Survey Requirements for Preble's Meadow Jumping Mouse). • The site is located in Weld County below 7400' elevation. • Property is in the 100 year flood plain of the Cache Poudre River. • A small wetland and gravel ponds are present on the property. • • However, the site is marginal Preble's habitat for the following reasons: • This site is a highly disturbed site. The Poudre River is deeply entrenched, heavily rip - rapped and sparsely vegetated (See attached photos). Disturbances have also been caused by fanning practices and heavy grazing practices on this site. The shrub component that could provide cover and hibernaculum for PMJM is very sparce along the river. Due to channelization, past and current grazing management, the riparian zone is narrow and is dominated by upland grasses and a narrow band of Plains Cottonwood (Populus deltoides) and Russian Olive (Elaeagnus angustifolia). Presence/absence surveys have been conducted in the vicinity of this property with no captures of PMJM. (Colorado Natural Heritage Program, Biodiversity Tracking and Conservation System, 3/24/07, Attachment 3). No impacts are expected to result from the proposed project because a 200' buffer will protect the river corridor and existing wetlands from any mining activities. Photos of the site are attached to this report Attachment 4. The Survey Field Data Compilation Form is located in Attachment 5. We look forward to your response.

The Service has reviewed the Preble's Meadow Jumping Mouse Habitat Assessment of the Parsons property, near Bracewell, Weld County, Colorado. Based on the information provided, the Service agrees that a population of Preble's (Zapus hudsonius preblei) is not likely to be present in the area. The Service concludes that the proposed project is not likely to adversely affect Preble's. Thus this site is disqualified for consideration under the ESA. Should additional information regarding listed or proposed species become available, this determination may be reconsidered. On February 2, 2005 the U. S. Fish and Wildlife Service issued a 12 -Month finding on a petition to delist Preble's. Because of the complexity involved, the Service has extended its original proposal. Until a final determination is made, Preble's remains protected under ESA. If we can be of further assistance, please contact Adam Misztal, of my staff, at (303) 236- 4753 or at email: adam_ misztal@fws.gov. Sincerely, J � C Susan C. Linner Colorado Field Supervisor • • • EXHIBIT I Soils Information Aquolls and Aquents, gravelly substratum This nearly level map unit is on bottom lands and flood plains of all the major streams in the survey area. Aquolls, which have a dark colored surface layer, make up about 60 percent of the unit. Aquents, which have a lighter colored surface layer, make up about 35 percent. About 5 percent is Aquepts and Bankard sandy loam. These are deep, poorly drained soils that formed in recent alluvium. No one pedon is typical. Commonly, the soils have a mottled, mildly alkaline to moderately alkaline loamy or clayey surface layer and underlying material and are underlain by sand and gravel and gravel within 48 inches. In places they have a gleyed layer in the underlying material. Most of the acreage is subject to flooding. The water table is at or near the surface early in spring and recedes to as deep as 48 inches late in fall in some years. These soils are used for rangeland and wildlife habitat. Some small areas have been reclaimed by major drainage and leveling and are used for irrigated crops. The potential native vegetation is dominated by alkali sacaton, switchgrass, and western wheatgrass. Saltgrass, sedge, rush, and alkali bluegrass are also prominent. Potential production ranges from 3,000 pounds per acre in favorable years to 2,000 pounds in unfavorable years. As range condition deteriorates, the switchgrass, alkali sacaton, and western wheatgrass decreases and saltgrass, sedge, and rush increase. Management of vegetation should be based on taking half and leaving half of the total annual production. Seeding is difficult and costly because numerous tillage practices are required to eliminate the saltgrass sod. Switchgrass, western wheatgrass, alkali sacaton, tall wheatgrass, and tall fescue are suitable for seeding. They can be seeded into a clean, firm seedbed. Seedbed preparation usually requires more than 1 year to eliminate the saltgrass sod. A grass drill should be used. Seeding early in spring has proven most successful. Wetland wildlife, especially waterfowl, utilize this unit. The wetland plants provide nesting and protective cover, as well as some food. The nearby irrigated cropland, where wildlife obtain much of their food and find protection cover, makes this unit valuable to both wetland and openland wildlife. Openland wildlife, especially pheasant, use this unit for cover and nesting. Deer find excellent cover in some areas. These valuable wildlife areas should be protected from fire and fenced to prevent encroachment and overuse by livestock. They should not be drained. Parsons Mine DRMS 112 Reclamation Permit Application Page 11 of 110 These soils have good potential as a source of sand and gravel. Capability subclass VIw; Salt Meadow range site. Bankard sandy loam, 0 to 3 percent slopes This is a deep, somewhat excessively drained soil on flood plans at elevations of 4,450 to 5,000 feet. It formed in stratified recent alluvium along streams and rivers. Included in mapping are numerous sand and gravel bars and small areas of noncalcareous soils. Typically the surface layer of this Bankard soil is brown and sandy loam about 4 inches thick. The underlying material to a depth of 60 inches is pale brown calcareous sand stratified with thin lenses of sandy loam, loam, and fine gravel. Permeability is moderately rapid. Available water capacity is low. The effective rooting depth is 60 inches or more. Surface runoff is slow, and the erosion hazard is low. This soil is suited to limited cropping. It is sandy and subject to flooding. Pasture is the best use. Tall wheatgrass, tall fescue, and annual sweetclover are some of the most suitable crops. Light, frequent irrigation by furrows and flooding is best. Commercial fertilizer improves the amount and value of forage produced. The potential native vegetation is dominated by switchgrass, indiangrass, sand bluestem, sand reedgrass, sideoats grama, needleandthread, and blue grama. Much of this range site includes other soils and vegetation in such a complex pattern that it is difficult to map them separately. Potential production ranges from 2,500 pounds per acre in favorable years to 1,500 pounds in unfavorable years. As range condition deteriorates, the tall and mid grasses decrease; blue grama, sand dropseed, and forbs increase; and forage production drops. Undesirable weeds and annuals invade the site as range condition becomes poorer. Management of vegetation should be based on taking half and leaving half of the total annual production. Seeding is desirable only in areas large enough to interseed or to prepare a seedbed. Switchgrass, sand bluestem, sand reedgrass, sideoats grama, little bluestem, blue grama, pubescent wheatgrass, and intermediate wheatgrass are suitable for seeding. This soil can be seeded by using an interseeder or a firm, clean sorghum stubble. A grass drill is required. Seeding early in spring has proven most successful. This soil is generally not suited to the establishment and growth of trees and shrubs. Onsite investigation is needed to determine feasibility and possible tree and shrub species. Wildlife is an important secondary use of this soil. The cropland areas provide favorable habitat for ring-necked pheasant and mourning dove. Many nongame species can be attracted by establishing areas for nesting and escape cover. For pheasants, undisturbed nesting cover is essential and should be included in plans for habitat development, especially in areas of intensive agriculture. Rangeland wildlife, for example deer and antelope, can be attracted by managing livestock grazing and reseeding where needed. Parsons Mine DRMS 112 Reclamation Permit Application Page 12 of 110 • • • • • • This soil is not suited to urban or recreational development because of the flood hazard. Capability subclass IVw irrigated, VIw nonirrigated; Sandy Bottom land range site. Colombo clay loam, 0 to 1 percent slopes This is a deep, well drained soil on flood plans and terraces at elevations of 4,600 to 4,780 feet. It formed in stratified calcareous alluvium. Included in mapping are small areas of soils that have a loam surface layer and some small leveled areas. Typically the surface layer of this Colombo soil is dark grayish brown clay loam about 14 inches thick. The upper 7 inches of the underlying material is pale brown stratified clay loam and loam. The lower part to a depth of 60 inches is very pale brown loam stratified with thin lenses of fine sand, medium sand, and clay loam. Permeability is moderate. Available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is slow, and the erosion hazard is low. In irrigated areas this soil is suited to crops commonly grown in the area, such as corn, sugar beets, beans, alfalfa, onions, and potatoes. All methods of irrigation that are common to the area are used. Borders are suitable for small grain, alfalfa, and pasture. Furrow irrigation is used for row crops. Crops respond to application of nitrogen and phosphorus. Windbreaks and environmental plantings of trees and shrubs commonly grown in the area are generally well suited in this soil. Cultivation to control competing vegetation should be continued for as many years as possible following planting. Trees that are best suited and have good survival are Rocky Mountain juniper, eastern redcedar, ponderosa pine, Siberian elm, Russian -olive, and hackberry. The shrubs best suited are skunkbush sumac, lilac, Siberian peashrub, and American plum. Wildlife is an important secondary use of this soil. Ring-necked pheasant, mourning doves, and many nongame species can be attracted to establishing areas for nesting and escape cover. For pheasants, undisturbed nesting cover is essential and should be included in plans for habitat development, especially in areas of intensive agriculture. Where the soil is on flood plains and is susceptible to flooding it has poor potential for urban and recreational development. On the higher terraces the potential is fair. Dwelling and road designs need to be modified to increase the capacity of the soil to support a load and to protect it against frost action. Capability subclass IIw irrigated. Parsons Mine DRMS 112 Reclamation Permit Application Page 13 of 110 Kim loam, 1 to 3 percent slopes This is a deep, well drained soil on smooth plains and alluvial fans at elevations of 4,900 to 5,250 feet. It formed in mixed eolian deposit and parent sediment from a wide variety of bedrock. Included in mapping are small areas of soils that have loamy sand underlying material. Typically the surface layer is brown and pale brown loam about 12 inches thick. The upper 28 inches of the underlying material is pale brown loam. The lower part to a depth of 60 inches is pale brown fine sandy loam. Permeability is moderate. Available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is medium, and the erosion hazard is low. In irrigated areas this soil is suited to all crops commonly grown in the area, including corn, sugar beets, beans, alfalfa, small grain, potatoes, and onions. An example of a suitable cropping system is 3 to 4 years of alfalfa followed by corn, corn for silage, sugar beets, small grain, of beans. Land leveling, ditch lining (fig. 6), and installing pipelines may be needed for proper water applications. All methods of irrigation are suitable, but furrow irrigation is the most common. Barnyard manure and commercial fertilizer are needed for top yields. In nonirrigated areas this soil is suited to winter wheat, barley, and sorghum. Most of the acreage is planted to winter wheat and is summer fallowed in alternate years to allow moisture accumulation. Generally precipitation is too low for beneficial use of fertilizer. Stubble mulch farming, striperopping, and minimum tillage are needed to control soil blowing and water erosion. Terracing also may be needed to control water erosion. The potential native vegetation is dominated by blue grama. Several mid grasses, such as western wheatgrass and needleandthread, are also present. Potential production ranges from 1,600 pounds per acre in favorable years to 1,000 pounds in unfavorable years. As range condition deteriorates, the mid grasses decrease; blue grama, buffalsograss, snakeweed, yucca, and fringed sage increase; and forage production drops. Undesirable weeds and annuals invade the site as range condition becomes poorer. Management of vegetation on this soil should be based on taking half and leaving half of the total annual production. Seeding is desirable if the range is in poor condition. Sideoats grama, little bluestem, western wheatgrass, blue grama, pubescent wheatgrass, and crested wheatgrass are suitable for seeding. The grass selected should meet the seasonable requirements of livestock. It can be seeded into a clean, firm sorghum stubble, or it can be drilled into a firm prepared seedbed. Seeding early in spring has proven most successful. Windbreaks and environmental plantings of trees and shrubs commonly grown in the area are generally well suited to this soil. Cultivation to control competing vegetation should be continued for as many years as possible following planting.

The cropland areas provide favorable habitat for ring-necked pheasant and mourning dove. Many nongame species can be attracted by establishing areas for nesting and escape cover. For pheasants, undisturbed nesting cover is essential and should be included in plans for habitat development, especially in areas of intensive agriculture. Rangeland wildlife, or example, the pronghorn antelope, can be attracted by developing livestock watering facilities, managing livestock grazing, and reseeding where needed. This soil has good potential for urban and recreational development. Increased population growth in the survey area has resulted in increased homesite construction. The chief limiting soil feature for urban development and road construction is the limited capacity of this soil to support a load. Septic tank adsorption fields function properly, but community sewage systems should be provided if the population density increases. Because of the permeability of the substratum, sewage lagoons must be sealed. Lawns, shrubs, and trees grow well. Capability subclass lie irrigated, IVe nonirrigated; Loamy Plains range site.

Parsons Mine DRIVE 112 Reclamation Permit Application Page 110 of 110 • • • • • • EXHIBIT J Vegetation Information General The Parson's Property is located in Colorado's Eastern Plains, within the Central Shortgrass Prairie Physiographic Region. The northern portion of the property is occupied by irrigated agricultural land. The Cache La Poudre River and its floodplain flows through the southern portion of the property. Elevation ranges between 4750 to 4710 feet. Habitat types include grasslands (including irrigated cropland and non -irrigated grazing pastures), wetlands and lowland riparian (along the river). Present Vegetation Types The majority of the property is occupied by irrigated cropland used to grow hay, corn and other row crops. Much of the property is maintained in irrigated and dryland pastures and is used for grazing. These areas are dominated by natural and introduced pasture grasses and are occupied by a significant number of invasive and noxious weed species. The Cache La Poudre River and its 100 year floodplain occupy the southern portion of the property. The property contains several wetlands which are under the jurisdiction of US Army Corp of Engineers (COE) through section 404 of the Clean Water Act. Wetland determinations were completed in accordance with standards specified by US Anny Corp of Engineers Wetlands Delineation Manual. An on -site inspection was conducted on June 12, 2007 and August 2, 2007. Terry McKee, US Army COE) visited the site on September 17, 2007 to confirm the wetland boundaries. Eleven wetland sites were identified on the property (Attachment J-3). The Poudre River (wetland site #2) is considered waters of the US and a portion of its adjacent banks and floodplains have been identified as jurisdictional wetlands (wetland sites 3 and 3A). A natural drainage that flows in the Poudre River from the south (wetland site 6) and a manmade drainage that flows into the river from the north (wetland site 7) are also jurisdictional wetlands. A large manmade pond (wetland site 9) and a cattail dominated wetland which has developed in a stock watering area (wetland 4) are all connected by manmade wetland channel (wetland sites 4A and 8) flowing into wetland site 7. Two excavated ponds (wetland sites #1 and 5) are present just north of the river. Wetland Site 5 is not considered jurisdictional because there is no surface connectivity to the river. Wetland Site #1 has not surface water connectivity but is adjacent and has ground water connectivity to the river. All wetland sites including those considered non -jurisdictional will not be mined or impacted by the project. Relationship of Present Vegetation to Soil Types The Soil Survey of Weld County Area, Colorado published in 1980 by the USDA, Soil Conservation Service was used to identify soils at the site. The soil series types and their relationship with the vegetation types within the project area include: Irrigated Croplands - Northern portion of the Property: Olney Fine Sandy Loam, 0 - 1 percent (map unit 46) - This soil type occurs on the northern portion of the property. Olney Fine Sandy Loams consists of deep, well drained soils that are formed in mixed outwash deposits.

The purpose of this report is to identify wetlands that fall under the jurisdiction of the US Army Corp of Engineers. This report will be used to quantify any potential wetlands impacts, direct avoidance where possible, and identify mitigation opportunities. As part of the field work, surveys for occurrences of and potential habitat for Ladies Tresses Orchid and Colorado Butterfly plant were conducted. This field work was conducted in June and August of 2007. PROJECT AREA The Parson's Gravel Site is located in Sections 30 and 31 of T6N, R66W, and Sections 25, 36 of T6N, R67W, (Bracewell, Colorado Quandrangle). The Poudre River flows through the southern portion of the property from 4718 to 4716 feet in elevation (UTM coordinates range from 13T 0513410E, 4477030N on the upper end of the river to 0514680E, 4477320N on the lower end of the river.) An excavated non jurisdictional pond (1.3 acres) exists on the southern portion of the property and a man-made pond (1.6 acres) occurs in the center of the property. Several ditches are present on the property. This property has historically been used for agricultural purposes, as cropland and irrigated pasture and for livestock grazing. It continues to be used as such. Elevation of the project area is from 4740 to 4716 feet. METHODS Wetlands were identified and mapped using the 1987 Corp of Engineers Wetland Delineation Manual. The COE manual defines jurisdictional wetlands as: • 1 "Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions." In order for an area to be classified as a jurisdictional wetland, the manual requires at least one indicator from each of three parameters: 1) hydrophytic vegetation; 2) hydric soils; and 3) wetland hydrology. VEGETATION Sample points were taken at several points within the project area. At each sample point, percent total cover of dominant plant species was estimated. The COE manual indicates that the vegetation requirement is met if the prevalent vegetation consists of macrophytes adapted to saturated soils. The US Fish and Wildlife Service's National List of Plant Species that Occur in Wetlands (Region 5) was used to classify plant species according to their likelihood of occurring in wetlands: OBL Obligate Wetland Plants FACW Facultative Wetland Plants FAC Facultative Plants FACU Facultative Upland Plants UPL Obligate Upland Plants NI No Indicator Species that occur almost always (>99% probability) in wetlands, and rarely occur in nonwetlands. Species that occur usually (67-99%) in wetlands, but also occur in non -wetlands Species with a similar likelihood (33-66%) of occurring in wetlands or nonwetlands. Species that occur sometimes (1-33%) in wetlands but occur more often in nonwetlands. Species that occur rarely (<1%) in wetlands but occur almost always in nonwetlands. Species for which insufficient information is available to determine its indicator status. Under normal circumstances, an area is considered to have hydrophytic vegetation when more than 50% of the dominant species, from all plant strata, are classified as either OBL, FACW, or FAC. Dominant species are those species in each stratum that, when ranked in descending order of estimated percent aerial coverage and cumulatively totaled, immediately exceed 50 percent of the total coverage. Additionally, any species comprising at least 20% of the total coverage for their respective stratum was also considered dominant. SOILS Each sample site was examined for the presence of hydric soils. Soils which are saturated or flooded long enough (usually a week or more) during the growing season to develop anaerobic conditions in the upper layers are classified as hydric. Typical field indicators of hydric soil conditions include; organic soils, thick organic layers, gleying (gray soil colors), and low soil chroma (intensity of soil hue) with or without redoxomorphic features (mottles). Low soil chroma and mottles are indicators of anaerobic conditions. Mottles usually indicate a fluctuating 2 • • • • • water table. Soils were analyzed for color using the Munsell Soil Color Chart. Soil color is based on hue, value, and chroma. The COE manual requires analysis of soil color immediately below the "A" horizon, or ten inches, whichever is less. A mineral hydric soil usually has either a matrix chroma of 2 or less in mottled soil, or a matrix chroma of 1 or less in unmottled soil. HYDROLOGY An area is considered to have wetland hydrology when the soil is inundated or saturated for a significant period (usually a week or more) during the growing season. Direct observation of hydrology can be made during the growing season or field indicators can be used. Primary indicators include visual observation of inundation or saturation, water marks, sediment deposits, and drainage patterns. Secondary indicators include the presence of oxidized rhizospheres (rust coloration around living roots), water -stained vegetation, morphological plant adaptations, and local soil survey data. In addition to evaluation of vegetation for identification of wetlands, presence of threatened or endangered plant species were also considered in this study. Two potential threatened and endangered species may occur in the vicinity: Utes Ladies Tresses Orchid (Spiranthes diluvialis) and Colorado Butterfly Plant (Gaura neomexicana coloradensis). RESULTS Preliminary data collection included reviewing and obtaining existing information, maps, and aerial photography. A wetland delineation was completed on the southern portion of the property in 2005 (Kemmerer, 2005). COUNTY SOIL SURVEYS The Soil Survey of Weld County Area, Colorado published in 1980 by the USDA, Soil Conservation Service was used to identify soils at the site (Exhibit II). The soil series type within the project area include: Aquolls and Aquents, gravelly substratum (Map unit 3) - These are nearly level soils on bottomlands and floodplains that occur across the center of the property. Aquolls and Aquents are deep, poorly drained soils that are formed in recent alluvium. No one pedon is typical. Soils typically have a mottled, mildly alkaline to moderately alkaline loamy or clayey surface layer and are layer of sand and gravel to 48 inches. The water table is at or near the surface in spring and during peak irrigation season. Thus these soils are subjected to excessive runoff. Wetlands 4, 7, 8, 9 and 10 occur in this soil type. Bankard Sandy Loam, 0 - 3 percent (map unit 10) - are deep, somewhat excessively drained soils on flood plains that occur along the Cache La Poudre River. They are formed in stratified • 3 recent alluvium along streams and rivers. A representative profile includes a surface layer of brown sandy loam about 4 inches thick underlain with pale brown, calcareous sand stratified with sandy loam, loam and fine gravel to 60". Bankard Sandy Loam soils have moderately rapid permeability and low available water capacity. Surface runoff is slow and erosion hazard by wind and water is low. Wetland 1, 2, 3, 6 and 7 occur in this soil type. Colombo Clay Loam, 0 - 1 percent (map unit 19) - and are located on the upper terrace of the Poudre River floodplain. Colombo Clay Loam soils are deep, well drained soils on flood plains formed in stratified calcareous alluvium. Typical surface layers consist of dark grayis brown clay loam about 14" underlain by a layer of very pale brown loam stratified with lenses of fine sand, medium snad and clay loam to 60". Colombo clay loam soils have moderately permeability and the high available water capacity. Surface runoff is slow. The hazard of erosion by wind and water is low. Wetland #7 occurs in this soil type. Kim Loam, 1 - 3 percent (map unit 32) - A small strip of Kim Loam soils occurs through the center of property above the Poudre River floodplain. These are deep, well drained soils on smooth plains and alluvial fans formed in mixed eolian deposits. A typical surface layer is brown and pale brown loam about 12 inches thick underlain by pale brown loam and pale brown fine sandy loam to 60 inches. Kim loam soils have moderate permeability and high available water capacity. Surface runoff is medium and erosion hazard is low. Nunn Clay Loam, 0 - 1 percent (map unit 41) - This soil type occurs on the south side of the Poudre River. These are deep, well drained soils on smooth plains and terraces formed in mixed alluvium and eolian deposits. A typical surface layer is grayish brown clay loam about 14 inches thick underlain by clay loam and sandy loam to 60 inches. Kim loam soils have moderately slow permeability and high available water capacity. Surface runoff is slow and erosion hazard is low. Olney Fine Sandy Loam, 0 - 1 percent (map unit 46) - This soil type occurs on the northern portion of the property. Olney Fine Sandy Loams consists of deep, well drained soils that are formed in mixed outwash deposits. A typical surface layer is grayish brown fine sandy loam about 15 inches thick underlain by very pale brown, calcareous fine sandy loam to 60 inches. Olney soils have moderate permeability and moderate available water capacity. Surface runoff is slow and erosion hazard is low. Otero Sandy Loam, 0 - 1 percent (map unit 50) - This soil type occurs on the northeast side of the property. Otero Sandy Loam soils consists of deep, well drained soils and are formed in mixed outwash and eolian deposits. Typical surface layer is brown sandy loam about 12 inches thick underlain by pale brown calcareous fine sandy loam to 60 inches. Otero Sandy Loam soils have rapid permeability and moderate available water capacity. Surface runoff is slow. The hazard of erosion by wind and water is low. Otero Sandy Loam, 3 - 5 percent (map unit 52) - A small strip of Otero Sandy Loam soils occurs through the center of the property above the Poudre River floodplain. These are deep, well drained soils on plains formed in mixed outwash and eolian deposits. A typical surface layer 4 • • • • • • is brown sandy loam about 10 inches thick underlain by pale brown calcareous fine sandy loam to 60 inches. Otero Sandy Loam soils have rapid permeability and moderate available water capacity. Surface runoff is medium. The hazard of erosion by wind and water is low NATIONAL WETLAND INVENTORY National Wetland Inventory (NWI) maps were unavailable for the property. WETLAND SITES An on -site inspection was conducted on June 12, 2007 and August 6, 2007. Eleven wetland sites were identified on the property. Site numbers were made to coincide with the delineation completed in 2005. A small excavated pond (Wetland Site #1) is present in the southern portion of the property just north of the river. A narrow band of Russian Olive, cottonwood trees and wetland vegetation is present along the shoreline of this pond. This pond has no surface water connection to the river. However, it is adjacent to the Poudre River and wetlands associated with the pond are within one vertical foot of the ordinary high water line of the river. Therefore, the COE would likely consider this a jurisdictional wetland. The Cache La Poudre River (Wetland Site #2) is considered waters of the US and is under the jurisdiction of the US Army Corp of Engineers. The wetlands that occur along the river banks, overflow channels and islands are dominated by a cottonwood overstory, Russian Olive shrub component and a narrow reed canary grass/common spikerush understory. The Poudre River is deeply entrenched, heavily rip -rapped and sparsely vegetated by wetland species due to vertical banks. Wetland Site #3 is an oxbow channel of the Poudre River, that is connected by an active channel and ground water and is therefore considered a jurisdictional wetland. It is dominated by cattail and common spikerush. Wetland site 3A is a small depressional wetland in the Poudre River floodplain. It is dominated by bulrush and surrounded by cottonwood trees. Since there is no direct hydrologic connection to the river, this site would likely not be considered a jurisdictional wetland. Buttercup, bulrush, and cattail dominate Wetland Site #4. This wetland is saturated to the surface over the majority of the site but has some standing water on the upper end. It is heavily grazed by cattle such that most of the ground is bare soil. This wetland is connected to wetland sites 7 and 8 and eventually flows to the Poudre River. It is, therefore, a jurisdictional wetland. Site 4A is an upland lateral ditch which flows into wetland 4. It is dominated by spikerush, bulrush and rush species. A few Russian olive trees occur along the ditch. Site 4A would most likely be considered a non jurisdictional wetland. 5 Wetland site #5 is a small excavated depression just north of Wetland #3. It is dominated by rush, spikerush, bulrush and rush. There is no surface water connection to the river or any ditches. Therefore, this is a non jurisdictional wetland. Wetland site #6 is a moist natural drainage in the southwest portion of the property. It is dominated by reed canary grass, common spikerush and red top. Since it drains directly into the Poudre River, it would be considered a jurisdictional wetland. Wetland site #7 is the major irrigation return channel approximately 10 feet wide draining wetland sites 8 & 9 and the agricultural fields to the north. It is dominated by reed canary grass and cattail along the banks and watercress in the channel. A few Russian Olive trees occur along the channel. This excavated channel connects to the Poudre River and is therefore a jurisdictional wetland. Wetland Site #8 is a man-made drainage flowing from Wetland Site 4. It is dominated by bulrush and spikerush. Cattails and three square bulrush also occupy the site. The hydrology is maintained by constant irrigation return flows from the property to the west. Wetland soils are present. A small amount of fresh dirt/manure fill was observed just inside the wetland boundary on August 6. Since this drainage has a hydrologic connection to the river, it would be considered a jurisdictional wetland. Wetand Site #9 is a man-made pond fed by irrigation water from the north. This site also includes the ditches above and below the pond. The shoreline has a very narrow band of wetland species including salt grass and redtop. The outlet channel, dominated by cattail, bulrush and spikerush confluences with wetland site #8 and flows to form the irrigation return channel wetland site 7. This would also be considered a jurisdictional wetland due to its connectivity to the Poudre River. Site #10 is a man-made irrigation ditch on the east -central portion of the property. The banks are comprised of wetland species including bulrush, spikerush and reed canary grass. This ditch would be considered jurisdictional if it has a hydrologic connection to the river. THREATENED AND ENDANGERED PLANT SPECIES Two species of threatened or endangered species that may occur in the project area are Utes Ladies Tresses Orchid (Spiranthes diluvialis) and Colorado Butterfly Plant (Gaura neomericana coloradensis). These species are known to occur in wetlands in Northern Colorado. Neither species was observed in the project area. Because of the historic use of the property, it is unlikely that either of these species occurs within the project area. 6 • • • • • • Table 1. Vegetation occurring within wetland areas.

This project is located in Sections 30 and 31. T6K R66W and Sections 25, 36, T6, Weld Count, Colorado. Mr. McKee considers vo.ar wetland report and wetland map for this project accurate and acceptable. Based on the information provied in your October 3, 2097 wetland report, a Department of the Area- (DA I Permit w 1l not be required for the proposed mining activity at this site. Although a DA Permit will not be required for the project. this does no; eliminate the requirement that other applicable federal. state, and local permits be obtained as needed. If however_ any work acociitcd with this project will require the placement of dredged or till material, and any excavation associated with a dredged or till project, either temporary or pe_manent, in c stream bed or wetland. this office should be notified by a proponent of the project for Department of the Arany permits or changes in permit requirements pnrsuant to Section 404 of the Clean Water Act. Work in a stream bed or wetland should he shorn on a map identiting the Quarter Section, Township, Range and County of the work and the dimensions of work in each area, any toss of stream bed or wetland may require mitigation. Mitigation requirement.swill be determined during the DA permitting review. 1: there are any questions ;all DIr.

With the mountains to the west, variations in temperature are wide. In the high plains area, rainfall is light and humidity is low. The average frost -free period is 172 days. Annual average precipitation is about 14 inches. In the eastern high plains area, the climate is modified considerably from that expected of a typical high plain because of the nearby mountains to the west. The winds characteristic of the plains are reduced somewhat by the shielding effect of the mountains. Climate data for the Site is assumed to be similar to that of a weather station at Greeley UNC, Colorado. The Western Regional Climate Center tracks temperature extremes and precipitation data for this station. The following table includes data that was collected between March 1, 1967 and April 30, 2009.

During the life of the mine, approximately 296 of the 381 acres will be disturbed by the mining activities. Of that area, approximately 60.0 acres will be covered with water once reclamation is complete. This site will be mined and reclaimed concurrently. There is an eagle's nest on land adjacent to the mining site that will impact phasing of the mining and reclamation. The reclamation cost estimate is based on the time in the process when Phase lA will be stripped and operating as the processing site, Phases 1B and 1C will be completely mined and partially reclaimed (due to limitations from the eagle), and Phase 2 will be stripped, partially mined and partially reclaimed. At this point, approximately 100 acres will be disturbed and in various stages of mining and reclamation. During this period, there would be a conveyor crossings over County Road 25 between Phases lA and Phase 2.

WITNESSET.II In consideration of the sum of paid by the Company to or on behalf of Lessor, the receipt of which is hereby acknowledged by Lessor, and on and subject to the terms and conditions provided in this Lease, Lessor hereby leases, lets and demises to the Company the Materials as defined herein, in, on and under the real property situate in Weld County, Colorado, and described in Exhibit A attached hereto and made a part of this Lease (hereinafter referred to as the "Property"), and the exclusive right to sample, drill, and test for, develop, mine, quarry, extract, process, sell, use and remove them during the Term of this Lease, along with the right to locate and use easements as defined herein. 1. Definitions. A. Effective Date shall mean the date first set forth above in the initial paragraph of this Lease. B. Lease Year shall mean a period of one year beginning on the Effective Date, or on any annual anniversary thereof. C. Materials shall mean stone, sand and gravel and any overburden and valuable solid minerals, other than hydrocarbon minerals such as coal, oil, gas and associated liquid hydrocarbons, that are removed incident to sand and gravel operations hereunder and which arc saleable and recoverable from the Property in the course of such operations. D. Net Sale Ton shall mean 2000 pounds of Materials from the Property actually sold or used in products that are sold, measured or weighed after any processing of such Materials. Processing of Material from the Property, including washing of sand and gravel, removes approximately ten to fifteen percent of the total Materials mined from the Property, which Materials arc not salable and not subject to payment of Production Royalty. If the Company weighs or measures Materials from the Property before processing (such as, but not limited to, weighing on a conveyor belt scale as it leaves the Property), the Company and Lessor shall agree upon a formula that reasonably reflects the loss of Materials in processing being experienced by the Company in the vicinity of the Property for purposes of calculating the Net Sale Tons for Production Royalty purposes. 2. Term. The Term of this Lease shall be an initial period of ten (10) years commencing on the Effective Date ("Term"). The Company may obtain an extension of the Term for five years by written notice to Lessor prior to the end of the initial Term and payment of the Advance Minimum Royalty for the eleventh Lease Year set forth in Paragraph 4, below. The period of any extension of the initial Term pursuant hereto shall likewise be considered to be within the Term of this Lease. 3. Production Royalties. A. For all Materials mined or quarried and removed and sold from the Property during each calendar month during the first five Lease Years, the Company shall pay to Lessor a royalty ("Production Royalty") derived from a "Base Royalty" rate of per Net Sale Ton. The Base Royalty rate shall be increased to per Net Sale Ton in the sixth and each succeeding Lease Year. The Production Royalty rate shall be adjusted from the Base Royalty rate at the start of the first five Lease Years, commencing January I, 2005 pursuant to Paragraph B below. Subsequent adjustments of the Production Royalty Rate shall be made pursuant to Paragraph C below. B. The Production Royalty rate for the first five Lease Years shall be adjusted annually, commencing on January 1, 2005 and on each January 1 thereafter (the "Adjustment Date"). The basis for this adjustment shall be the Consumer Price Index —All Urban Consumers —Denver -Boulder -Greeley Area, published by the United States Department of Labor, Bureau of Labor Statistics (the "Index"). The adjusted Production Royalty shall be determined by dividing the monthly Index last published before such Adjustment Date by the monthly Index last published as of the Effective Date and then multiplying the quotient by the Base Royalty so as to adjust the Production Royalty rate per ton beginning on the first Adjustment Date and each subsequent Adjustment Date thereafter based on such calculation. The foregoing ratio of Indexes shall be calculated on data with base year 1982 = 100 until the Bureau of Labor Statistics publishes data with a new base period. If the Index just described or one reasonably similar thereto is no longer published, then an index or adjustment accomplishing as nearly as practical the result which would have been obtained by using the stated Index if it had been available shall be selected by agreement of the parties hereto. C. The Base Royalty for the sixth Lease Year and each succeeding Lease Year shall be fixed at ; per Net Sale Ton. Commencing January 1, 2010 and on each January 1 thereafter, the Production Royalty rate shall be adjusted from this new Base Royalty rate for the remaining initial Lease term, as well as any extension of the initial Term, in the manner described in Paragraph B, above, except that the reference Index to be used in calculating the ratio for adjustment of the Production Royalty from the Base Royalty in the sixth and succeeding Lease Years shall be the monthly Index last published before commencement of the sixth Lease Year (instead of the Index last published as of the original Effective Date). D. Production Royalty for each calendar month, in excess of amounts prepaid pursuant to Paragraph 4, below, shall be paid to Lessor within twenty (20) days after the close of such calendar month. The royalty payments shall be accompanied by a monthly statement with -2- • • • • • the royalty calculation that includes an accounting of the tons of Materials mined from the Property and sold for the month. E. The Company shall keep and maintain adequate and accurate records of the quantities sold for Materials mined, removed, and sold. Lessor shall have the right at all reasonable times during business hours and upon reasonable prior notice to examine such records of the Company at the offices of the Company and to verify the quantities of Materials mined, removed, and sold and the accuracy of the scales used to weigh the Materials. 4. Minimum Royalties. The initial paid to Lessor at the time this Lease becomes effective shall be deemed "Advance Minimum Royalty" (or "AMR") and shall apply to maintain the Lease in effect for the period commencing on the Effective Date until the end of the first Lease Year. Thereafter, the Company shall pay the following amounts as Advance Minimum Royalty to keep the Lease in effect for each Lease Year after the first: Second Lease Year - Third Lease Year and Fourth Lease Year - Subsequent Years of Lease Agreement (as extended) to Depletion of Reserve - AMR of $ AMR of $ AMR of $ provided that, at such time as the Company has paid Lessor at least in Advance Minimum Royalty and Production Royalty in excess of that recouped from Advance Minimum Royalty, the obligation to pay Advance Minimum Royalty shall cease. The Advance Minimum Royalty payments for a Lease Year shall be due on or prior to commencement of that Lease Year. Advance Minimum Royalty payments made under this Lease shall be credited as an advance payment of and applied to reduce Material tonnages otherwise subject to the Production Royalty pursuant to Paragraph 3, based upon the tonnage associated with the Production Royalty rate in effect at the time the Advance Minimum Royalty is paid. (For example, the paid upon execution of this Lease shall be deemed advance payment of Production Royalty at the Base Rate of per Net Sale Ton for 100,000 Net Sale Tons of Materials from the Property, whenever sold under this Lease. If the Index ratio of Paragraph 3.B. has become 1.05 at the time the Advance Minimum Royalty payment for the third Lease Year is made, thus making the Production Royalty rate cents per Net Sale Ton, then the payment made shall be deemed advance payment of Production Royalty for per Net Sale Ton, or 142,857 Net Sale Tons of Materials, whenever removed and sold thereafter under this Lease). Production Royalties paid pursuant to Paragraph 3, after taking into account and in excess of Advance Minimum Royalties paid pursuant to this Paragraph, shall be applied in succeeding years to reduce amounts subsequently payable as Advance Minimum Royalty. Upon termination of this Lease for any reason, and subject to the Company's early termination payment obligation under Section 15(F), the obligation to make Advance Minimum Royalty payments shall likewise terminate except as to payments that became due prior to termination. -3- There is no implied covenant or obligation of the Company to develop or mine the Property or to sell Materials. The Company may maintain this Lease in effect for the term of the Lease by making the annual Advance Minimum Royalty payments. If for whatever reason, Advance Minimum Royalties exceed the Production Royalties at termination of this Lease (or at any other time during the Lease Term), Lessor shall have no obligation to return any Advance Minimum Royalties paid by the Company, except as otherwise provided in Paragraph I 2B. 5, Commingling. When Materials are excavated from the Property, they may be transported to the offsite processing plant by a series of conveyors and/or trucks, and commingled with Materials from lands other than the Property. Prior to commingling Materials from the Property with Materials from lands other than the Property the Company shall first measure and determine the quantity of Materials in the stockpile in accordance with its standard engineering methods, and shall also measure and record the amount added to and commingled in the same stockpile from Property. The quantity of Material so determined to be in the stockpile immediately before commingling shall be deemed sold and removed, on a first -in first -out basis, prior to the sale of any Materials subsequently commingled therewith. The Company's measurement and determination shall be subject to verification by the Lessor. 6. Water Augmentation and Dewatering. The Company shall be responsible for supplying all water needs during its mining and processing operation, including without limitation, evaporation losses occurring from groundwater exposed by mining during the operations. Upon completion of mining operations, Lessor shall be responsible for supplying Five (5) shares of the capital stock of the Whitney Irrigating Ditch Company owned by Lessor (the "Water Stock") for augmentation or replacement of evaporative losses on exposed water surfaces of the Property. The Company shall be responsible for adjudicating the augmentation plan as to the Lessor's Property. In this regard, Lessor expressly agrees to dedicate in perpetuity the Water Stock evidenced by five (5) shares of the capital stock of the Whitney Irrigating Ditch Company owned by Lessor for such augmentation purposes and agrees to consent to or enter into such consent decrees, restrictive legends on stock certificates, restrictive covenants or other evidence of such dedication and encumbrance as may reasonably be necessary to preserve such Water Stock for augmentation purposes, evidence the obligation to use them for augmentation and obtain approval of an augmentation plan related to the Property from the Water Court or State Engineer, as applicable. Lessor's augmentation related obligations shall be limited to supplying the Water Stock. 7. Operations. A. The Company shall conduct its operations on the Property in a prudent and workmanlike manner and in accordance with good and accepted mining and business practices and in compliance with all applicable federal, state and local laws, rules and regulations. The timing, nature, manner and extent of mining operations, processing and sales shall be within the sole discretion of the Company, and the Company shall not be required to mine, preserve or protect in its operations any Materials which, under good mining practices, cannot be mined or sold at a reasonable profit to the Company at the time they are extracted.

The Company shall have the right during the Term of this Lease and without payment to Lessor (except for Production Royalties payable pursuant to Paragraph 3 and Advance Minimum Royalties payable pursuant to Paragraph 4) to strip and remove overburden and otherwise to use and occupy the Property as is reasonably required in connection with mining, quarrying, extracting, processing, storage, transportation, sale and removal of Materials from the Property on which the Company is conducting operations. C. The Company shall consult with Lessor with respect to all permit applications, plans and designs of the Company; provided, however, that all final decisions on mine plans, operations, reclamation, permits and other plans of operations shall be in the Company's sole discretion and control. D. Lessor authorizes the Company on Lessor's behalf and agrees to cooperate with the Company at no additional costs to the Lessor to apply for and obtain zoning or other governmental land use classifications, permits, approvals, licenses, and rights (hereinafter "authority") that are reasonably required in connection with the operations that are contemplated under this Lease; provided, however, the Company shall provide bonds or other financial assurance for its operations, including for the restoration, reclamation or rehabilitation of the Property, as may be required or advisable to obtain such permits and approvals. 8. Conveyer Easement. In addition to the other rights granted under this Lease, Lessor hereby grants to the Company an easement for the term of the Lease to erect, operate, maintain, repair and relocate a conveyor system on, over and across the Property for the purpose of conveying Materials across the Property to the Company's processing plant on the Etters Property from any pit on the Property. Such easement shall include the right of vehicular access for construction, installation, repair, operation, relocation and removal of the conveyor system. 9, Waiver of Lateral Support.

If any title defects which render the title unmarketable or adversely affect the Company's right to mine are not cured within sixty (60) days after receipt of such notice, the Company, at its option, may terminate this Lease without any further obligation to Lessor. The Company shall, as part of such termination, have the right at its option to have any and all prepaid royalties not offset by Production Royalties refunded to the Company. C. Without regard to the warranties of title given to the Company by Lessor, if Lessor own less than one hundred percent (100%) of the Materials under all or any portion of the Property, then the amounts payable to Lessor hereunder as Advance Minimum Royalty payments and Production Royalties shall be reduced in the proportion that the interest of the Lessor in the Materials bears to one hundred percent (100%) of the Materials allocated to the Property. D. With the exception of existing oil and gas leases, Lessor shall not hereafter lease or otherwise authorize oil and gas rights or operations on the Property during the Term of this Lease, except under conditions which prohibit surface entry or occupancy and interference in any manner with the Company's operations on the Property.

Vecchi Carl Mount GRAVEL PROPERTY LEASE THIS INDENTURE, dated this 3 day of 11/4...5 s 4- , 2005 (hereinafter referred to as this "Lease"), by and between the Dr. Sally Parsons, whose address is 4020 14th Street, Greeley, Colorado 80634 (hereinafter referred to as "Lessor") and LAFARGE WEST, INC., a Delaware corporation (hereinafter referred to as the "Company"), with its address at 10170 Church Ranch Way, Suite 200, Westminster, CO 80021, Attention: General Manager Aggregates. WITNESSETH In consideration of the sum of fifteen thousand dollars non-refundable paid by the Company to or on behalf of Lessor, the receipt and sufficiency of which is hereby acknowledged by Lessor, and on and subject to the terms and conditions provided in this Lease, Lessor hereby leases, lets and demises to the Company the Materials as defined herein, in and under the real property situate in Weld County and described in Exhibit A attached hereto and made a part of this Lease (hereinafter referred to as the "Property"), and the exclusive right to sample, drill, and test for, develop, mine, quarry, extract, process, sell, use and remove them during the Term of this Lease and with associated easements as provided herein. 1. Definitions. A. Lease Year shall mean a period of one year beginning on the date which the Lease is executed by Lessor or on any annual anniversary thereof. B. Materials shall mean stone, sand and gravel and any overburden and valuable solid minerals, other than hydrocarbon minerals such as coal, oil, gas and associated liquid hydrocarbons, that are removed incident to sand and gravel operations hereunder and which are saleable and recoverable from the Property in the course of such operations. C. Permit Issuance shall mean receipt by the Company of written authorization by all applicable governmental authorities, on terms and conditions reasonably satisfactory to the Company, of all permits, consents and authorizations necessary for the Company to extract and process Materials from the Property including, without limitation, a mining and reclamation permit from the Colorado Division of Minerals and Geology, and a conditional or special use permit from Weld County D. Plant shall mean a portable and/or fixed facility for processing, storing, washing, sorting, handling loading and shipping of Materials, along with ancillary facilities. 2. Tenn. The Term of this Lease shall be an initial period of fifteen (15) years commencing on the 1st day of April 2005, and ending on the 30th day of March 2020, ("Term"). Provided the Company is conducting commercial mining operations at the end of the initial Term, the Company may obtain an extension of the Term for (1) additional three (3) year term. • • • • • • 3. Sales Royalties. A. Subject to Paragraphs 3.13. and 4, for all Materials sold from the Property during each calendar month, the Company shall pay to Lessor a royalty at the rate of per sales ton of 2,000 pounds (the "Base Royalty") within twenty (20) days after the close of such calendar month. B. The Base Royalty rate shall be adjusted every year on the first day of the month following the anniversary of the date this Lease becomes effective (the "Adjustment Date"). The basis for this adjustment shall be the Producer Price Index —Construction Sand/Grave]Crushed Stone —Series ID No. WPU 1321, published by the United States Department of Labor, Bureau of Labor Statistics (the "Index"). The adjusted Base Royalty shall be determined by dividing the monthly Index last published before such Adjustment Date by the monthly Index last published when this Lease becomes effective and then multiplying the quotient by the Base Royalty so as to increase the Base Royalty rate per ton beginning on the first Adjustment Date and each subsequent Adjustment Date thereafter based on such calculation. The foregoing ratio of Indexes shall be calculated on data with base year 1982 = 100 until the Bureau of Labor Statistics publishes data with a new base period. If the Index just described or one reasonably similar thereto is no longer published, then an index or adjustment accomplishing as nearly as practical the result which would have been obtained by using the stated. Index if it had been available shall be selected by agreement of the parties hereto. The royalty shall never be adjusted to below per sales ton during the term of the lease. C. The Company shall keep and maintain adequate and accurate records of the quantities of Materials mined and sold. The royalty payments shall be accompanied by a monthly statement with the royalty calculation that includes an accounting of the tons of Materials mined from the Property and sold or deemed sold pursuant to Paragraph S.C. for the month. Lessor shall have the right at all reasonable times during business hours and upon reasonable prior notice to examine such records of the Company at the offices of the Company and to verify the quantities of Materials removed, and sold and the accuracy of the scales used to weigh the Materials. 4. Advance Minimum Royalties. The initial non- refundable , paid to or for the benefit of Lessor at the time this Lease becomes effective shall be deemed "Advance Minimum Royalty" and shall apply to maintain the Lease in effect for the period commencing on the date this Lease becomes effective until the end of the first Lease Year. In addition to the initial Advance Minimum Royalty paid or credited when this lease becomes effective, Advance Minimum Royalty shall be paid annually at the rate of for each subsequent Lease Year prior to Permit Issuance and shall increase to $ per Lease Year at the start of the first Lease Year commencing after Permit Issuance has occurred. Notwithstanding the foregoing, the cumulative amount of Advance Minimum Royalty and sales royalty the Company is required to pay during the term of this Lease shall in no event exceed the equivalent of the sales royalty (using the Base Royalty rate) on eighty percent (80%) of the mineable and permitted quantity of the Materials that the Company determines are economically recoverable and salable from the Property (after processing and allowing for rejection of tailings), based upon calculations in accordance with recognized industry standards and practices. -2- Base Royalties paid pursuant to Paragraph 3, after taking into account Advance Minimum Royalties paid pursuant to this Paragraph, shall be applied in succeeding years to reduce amounts subsequently payable as Advance Minimum Royalty. Upon termination of this I Pa se for any reason, the obligation to make Advance Minimum Royalty payments shall likewise terminate except as to payments that became due prior to termination. There is no implied covenant or obligation of the Company to develop or mine the Property or to sell Materials. The Company may maintain this Lease in effect for the term of the Lease by making the annual Advance Minimum Royalty payments described in this Paragraph 4. 5. Weighing of Materials; Commingling. For purposes of calculation of Production Royalty, quantities of Materials removed from the Property on which Production Royalty is due will be measured as follows: A. Use of Scales. All Materials shall be weighed on a certified scale upon sale and removal from the Company's Plant site. If Materials on which Production Royalty is due are mixed with non -excavated materials (for example, in case of mixing sand and gravel with water and Portland cement in the concrete batch Plant), then for the purpose of calculating the Production Royalty, the weight of the Subject Minerals used in the mixture will be determined using the certified scales at the batch Plant that measure the weight of the materials that comprise the mixture and deducting the weight of the added non -excavated materials, if necessary. B. Scale Adjustments. Accuracy of the scale shall be checked and adjustments made at least as often as required to continue to be certified. Records of the accuracy check and adjustments shall be preserved and made available in the same manner as other records. C. Commingling. The Company may commingle Materials extracted from the Property with Materials extracted and removed from other properties. In order to fairly and properly allocate production between properties from which commingled Materials are extracted, the pit -run Materials extracted from each property shall be weighed prior to commingling on certified conveyor belts scales upon removal from the relevant property. Records will be kept as to the tonnages removed from each property, and the total production for each calendar month will be attributed to each property pro -rata, after adjustment of the total tonnage of pit tun from all properties for washed fines and tailings pursuant to Paragraph 5.D. below. Materials from one property added to a stockpile at any time during a calendar month shall be deemed added simultaneously and pro rata with Materials from any other Property. The quantity of material determined to be in the stockpile as of the commencement of any calendar month shall be deemed sold and removed, on a first -in first -out basis, prior to the sale of any Materials added to the stockpile during a subsequent calendar month. The Company's measurement and determination shall be conclusive. D. Allowance for Tailings. Tonnage for purposes of calculation of Production Royalty shall be based on processed Materials sold. If Materials are not being commingled from separate properties, then the tonnage sold shall be calculated pursuant to Paragraph S.A. above. If due to commingling, Materials are weighed as pit run before processing and sale by the Company pursuant to Paragraph 5.A., above, the weight of tailings and washed fines shall be deducted from the -3- • • • • • • total pit run weight of the Materials attributed to each property for purposes of calculating Production Royalties. Both parties agree that as much as approximately twenty percent (20%) of the minable in situ (in place, in the ground) sand and gravel onsite may need to be rejected as washed fines or tailings or otherwise in order to meet commercial specifications for salable Material. 6. Water Augmentation and Dewatering. A. During the term of this Lease, and until reclamation of the Property is completed, the Company shall provide at its sole cost and expense any and all water required to satisfy the requirements of state law including, without limitation, the requirements of CRS 37-90-137(11). The Company's temporary substitute supply plan or augmentation plan for supplying such water shall make adequate provision for evaporative losses, wash plant operations, dust control and any other uses of water as part of the mining operation. The Company shall notify Lessor in writing when it believes it is within three years of completion of mining operations. Lessor agrees that within one year after such notice, or if no such notice is given, within one year after the Company completes all operations on the Property, including earth work reclamation and excluding revegetation, seeding or weed control, Lessor will apply for, at Lessor's sole cost and expense, a permanent augmentation plan to cover any evaporative losses resulting from mining operation after termination of operations under the Lease, such plan expressly to become effective upon the cessation of mining operations by the Company. The Company will use commercially reasonable efforts in developing a final reclamation plan that will minimize the permanent augmentation requirements of the Lessor. B. The Company hereby grants to Lessor a perpetual non-exclusive easement to use the Company's groundwater recharge pond ("Recharge Pond") on the Company's Etters property adjoining the Lessor's Property in connection with Lessor's water augmentation obligations under this Lease or otherwise. Such easement includes the right to convey water under rights owned or controlled by Lessor on, over and across the Company's property, through the Whitney Ditch or other structures installed or constructed by Lessor, to the Recharge Pond at locations reasonably satisfactory to the Company and, subject to physical availability of storage space, to discharge such water into the Recharge Pond. Lessor shall be solely responsible for constructing any improvements necessary to divert and convey the water to the Recharge Pond, obtaining suitable water rights for such discharge and obtaining water court approval of any augmentation plan necessary for Lessor's use of Recharge Pond. if consent of the owners of the Whitney Ditch is necessary to convey water under Whitney Ditch rights to the Recharge Pond, or to carry water through the Whitney Ditch to the Recharge Pond under other water rights, Lessor shall be solely responsible for obtaining such consent. The Company shall reasonably cooperate in Lessor's applications and agreements to obtain necessary authorizations from governmental entities or third parties for use of the Recharge Pond as described above. Diversion, storage and discharge of water by Lessor into the Recharge Pond shall be conducted in compliance with applicable laws. The Company reserves the right to relocate any diversion or water conveyance structures or the Recharge Pond on its property. 7. Operations. A. The Company shall conduct its operations on the Property in a prudent and workmanlike manner and in accordance with good and accepted mining and business practices and in compliance with all applicable federal, state and local laws, rules and regulations and all -4- applicable permits. The timing, nature, manner and extent of mining operations, processing and sales shall be within the sole discretion of the Company, and the Company shall not be required to mine, preserve or protect in its operations any Materials winch, under good mining practices, cannot be mined or sold at a reasonable profit to the Company at the time they are encountered. B. The Company shall have the right to construct, maintain, and use roads, pipe lines, power lines, telephone lines, and stockpile areas and any right-of-way it deems necessary or desirable for its operations on the Property related to the Company's operations under this Lease. The Company shall have the right during the Term of this Lease and without payment to Lessor (except for Production Royalties payable pursuant to Paragraph 3 and Advance Minimum Royalties payable pursuant to Section 4) to strip and remove overburden and otherwise to use and occupy the Property as is reasonably required in connection with mining, quarrying, extracting, processing (including tailings -washed fines storage facilities), storage, transportation, sale and removal of Materials from the Property and from other properties on which the Company is conducting operations. The Company will not remove overburden from the Property, and will attempt to use unmineable materials from the adjoining Etters property in the reclamation design and reclamation construction for the Property. C. The Company shall not have the right to construct and maintain Plants on the Property. The Lessor, which agreement shall not be unreasonably withheld, shall agree upon access easements and the location and alignment or realignment of any conveyor. Any access easement and conveyor easement shall be 50 feet in width. Any conveyor easement shall include but not be limited to the right to construct, operate, maintain, repair and remove a conveyor system and similar, related or incidental improvements for purposes of transporting Materials across the Property. The Company shall have the right to place washed fines in mined out areas at no additional cost to Company under this Lease at mutually agreed upon locations. D. The Company shall consult with Lessor with respect to all permit applications, plans and designs of the Company; provided, however, that all final decisions on mine plans, operations, permits and other plans of operations shall be in the Company's sole discretion and control. The Company agrees to use commercially reasonable efforts to investigate and negotiate with the Lessor mutually beneficial reclamation plans and other operations utilizing the Company's equipment and expertise that will accommodate, facilitate and enhance Lessor's development of the Property and provide a mutually agreed upon reclamation plan. To the extent such agreed plan exceeds the cost of customary reclamation plans required by the Colorado Division of Minerals and Geology, using typical reclamation expenses and costs as a guideline, the additional costs and expenses pertaining to reclamation items (additional trees, seed mixes, etc.) will be the financial responsibility of the Lessor. E. Lessor hereby authorizes the Company, at the Company's expense and in Lessor's name, if required, to apply for zoning classifications, variances or exceptions, and governmental approvals, permits, licenses or rights related to and required for the Company's operations hereunder, and agrees to cooperate with the Company in obtaining such approvals and to execute or join in applications, plats and other documents which are required to obtain the same that -5- • • • • • • are reasonably required in connection with the operations that are contemplated under this Lease; provided, however, the Company shall provide bonds or other financial assurance for its operations, including for the restoration, reclamation or rehabilitation of the Property, as may be required or advisable to obtain such permits and approvals. P. The Company is aware that there is currently a farm lease and an oil and gas lease on the Property. In planning and conducting its operations on the Property, the Company will work with Lessor to minimize damage to crops and the oil and gas operations currently conducted on the Property. The Company shall pay Lessor and/or the current farm tenant the reasonable value of any crops growing on the Property which are destroyed or damaged by operations conducted by the Company on the Property under this Lease while the current farm lease is in effect. The Company shall also be responsible for any damages its operations cause to any vested right of the existing oil and gas lessee on the Property. Rights of any future oil and gas lessees are subject to Paragraph 11.D. G. Lessor shall have the right in the future to continue farming operations on the Property during the Term of this Lease, if and to the extent that those operations do not interfere in any manner with the Company's current or planned operations.

Additionally, please refer to Sheet 2 of Exhibit C which depicts the location of each structure. A Slope Stability Analysis was prepared for the Parsons Mine to determine the recommended setback from the mining operations to the structures. As you will see on the attached table, the recommended setback has been met or exceeded for all of the man-made structures within 200 feet of each mining cell. We are currently working to obtain a Structure Agreement with each of the structure owners listed in the attached table. A summary of the status of Structure Agreements, as well as copies of the currently signed agreements and proof of notice for some of the agreements is attached. Copies of the in -process agreements will be forwarded to the DRMS as they are executed. In addition, attached you will also find a copy of a signed agreement between Kinder Morgan, Lafarge West, Inc. and Livingston Leigh Livestock of Weld County, LLC. This agreement shifts the location of a pipeline easement that traversed the Livingston Leigh Livestock of Weld County, LLC property along the west edge of County Road 25.

The purpose of this analysis was to investigate appropriate mining-highwall setback distances from man made structures. Below we present a brief background and the results of our findings. Background The site is located east of the city limits of Windsor, Colorado. Weld County Road (WCR) 64'1 forms the northern boundary. WCR 25 bisects the site. The Cache La Poudre River flows through and adjacent to the southern portion of the site. The proposed gravel mine is to be mined with a highwall slope inclination of approximately 0.5:1 (horizontal to vertical). After mining, a final reclamation slope of 4:1 or flatter will be constructed using on -site overburden soils. Analysis Our stability analysis involved generating a computer model of limit equilibrium analysis using the Slope/W computer program. In addition to the mining highwall, long-term stability of the reclaimed slope was also evaluated. The stratigraphy, encountered during the March 2002 to April 2007, site investigations was used to develop the model. Sandy clay layers are typically encountered in the alluvial sand and gravel stratum. These layers are colloquially known as "mud lenses." No significant mud lenses were encountered during the investigation of this site. Therefore, mud lenses were not incorporated in the slope stability model. A worst case cross section was used to evaluate the set back distances for each phase during mining. The worst case of these was used for the long term reclaimed slope. A description of each cross section is presented below. The soil information used for our analysis came from six test pits and 45 borings. The various exploration locations used in our analysis are shown on Figure 1 and the information gained the soil explorations is summarized on Table 1 below. Copies of the exploration logs are attached.

Therefore a worst case scenario is represented by the north mining highwall of this phase. The soil profile analyzed was based on a conglomeration of soil information from exploration locations ET02-BH06, ET02-TP03, ET02-BH05, No.1, No.2 and MW -3. The model analyzed; a soil overburden that was 9 feet thick, a sand and gravel layer that was 21 feet thick, and a total pit depth of 30 feet. The highest groundwater monitored in the area was in MW -3 approximately 10 feet below the ground surface. A soil screening berm was placed north of the pit. Flood irrigation, north of WCR 641/2, was simulated by raising the piezometric surface, under the road and in the borrow ditch just south of the existing road, above the highest monitored surface to the ground surface. The road is planned to be widened. The widening will result in the ditch being relocated southward. Phase 1B The deepest depth to bedrock near a structure occurs near the northwest portion of the mining cell. The soil profile analyzed was based on a conglomeration of soil information from exploration locations ET02-BH01, ET02-TP05, No.9, No.10 and MW -1. The model analyzed; a soil overburden that was 9 feet thick, a sand and gravel layer that was 19 feet thick, and a total pit depth of 28 feet. The highest groundwater monitored in the area was in MW -1 approximately 10 feet below the ground surface. An overburden stockpile was placed northwest of the pit. No flood irrigation is near this mining cell; therefore the piezometric surface was based on the site monitoring. Phase IC The deepest depth to bedrock near a structure occurs near the northwest portion of the mining cell. The soil profile analyzed was based on a conglomeration of soil information from exploration locations PA04-BH07, No.5 and MW -13. The model analyzed; a soil overburden that was 6 feet thick, a sand and gravel layer that was 14 feet thick, and a total pit depth of 20 feet. The highest groundwater monitored in the area was in MW -1 approximately 9 feet below the ground surface. An overburden stockpile was placed northwest of the pit. No flood irrigation is near this mining cell; therefore the piezometric surface was based on the site monitoring. • • • Parsons Mine DRMS 112 Permit Page SE3 of SE8 • • • Phase 2 Eastside The depth to bedrock in this area is greatest in the middle of the mining cell. Therefore a worst case scenario is represented by the middle of the east mining highwall of this phase. The soil profile analyzed was based on a conglomeration of soil information from exploration locations L103-BH01, ET02-TP06, No.3, No.9 and MW -4. The model analyzed; a soil overburden that was 8 feet thick, a sand and gravel layer that was 21 feet thick, and a total pit depth of 29 feet. The highest groundwater monitored in the area was in MW -4 at an approximate elevation of 4731. An overburden stockpile was placed east of the pit. No flood irrigation is near this mining cell; therefore the piezometric surface was based on the site monitoring. Phase 2 Westside Due to the presence of flood irrigation to the west of this mining phase a second cross section was analyzed on the west side. The depth to bedrock in this area is greatest in the middle of the mining cell. Therefore a worst case scenario is represented by the middle of the west mining highwall of this phase. The soil profile analyzed was based on a conglomeration of soil information from exploration locations L103-BH02 and MW -6. The model analyzed; a soil overburden that was 10 feet thick, a sand and gravel layer that was 16 feet thick, and a total pit depth of 26 feet. The highest groundwater monitored in the area was in MW -6 approximately 9 feet below the ground surface. Flood irrigation, west of the mining cell, was simulated by raising the piezometric surface, at the fenceline (40 -feet from the mining highwall), above the highest monitored surface to the ground surface. Phase 3 The depth to bedrock in this area is greatest near the southern portion of the mining cell. Therefore a worst case scenario is represented near the southern portion of the mining highwall of this phase.

The highest groundwater monitored in the area was in MW -9 approximately 8 feet below the ground surface. An overburden stockpile was placed south of this mining cell. No flood irrigation is near this mining cell; therefore the piezometric surface was based on the site monitoring. Longterm This stability run uses the lithology of Phase I A. The soil profile analyzed was based on a conglomeration of soil information from exploration locations ET02-BH06, ET02-TP03, ET02-BH05, No.1, No.2 and MW -3. The model analyzed; a soil overburden that was 9 feet thick, a sand and gravel layer that was 21 feet thick, and a total pit depth of 30 feet. The highest groundwater monitored in the area was in MW -3 approximately 10 feet below the ground surface. Flood irrigation, north of WCR 64t/, was simulated by raising the piezometric surface, under the road and in the borrow ditch just south of the existing road, above the highest monitored surface to the ground surface. The road is planned to be widened. The widening will result in the ditch being relocated southward. Parsons Mine DRMS 112 Permit Page SE6 of SE8 DRMS Analysis, High wall Setback to Property Line The Division of Reclamation Mining and Safety (DRMS) requires that gravel pit highwalls within 200 feet of significant manmade permanent structures (such as utilities) be investigated for slope stability. Furthermore, the DRMS requires that the gravel mine highwalls be modeled as vertical unless it can be demonstrated that the slope angle of the highwall will be controlled during mining. Additionally, the DRMS requires that the analysis be performed using the DRMS parameters for sites where laboratory testing is absent. These parameters are given below on Table 2: Table 2: DRMS Model Parameters Soil Type Effective Friction Angle O' (degrees) Effective Cohesion c' (psi) Saturated Unit Weight Xot (PO Overburden 28 50 114 Gravel 35 0 130 Weathered Bedrock 14 0 124 Bedrock 28 100 124 The parameters for weathered bedrock are much more conservative than those typically encountered in the project area and, it is our opinion, that they are not representative of conditions at the site. We analyzed a vertical highwall section for each phase. The depth to bedrock varied from 7 to 31 feet across the project site. The vertical section corresponds to a steep highwall mining scenario where the highwall inclination is approximately 0.5:1. Table 3 below summarizes the results of our analysis. The analysis was performed using the DBMS parameters shown in Table 2. The factor of safety required by the DRMS for temporary mine slopes and reservoir embankments are provided for comparison. Output graphics for each of the analyses are attached.

Parsons Mine DRMS 112 Permit Page SE7 of SE8 • • • • • • Inflow and Outflow Structures In order to mine within 400 feet of the Cache la Poudre River, the Division of Reclamation Mining and Safety (DRMS) requires the construction of engineered inflow and outflow structures. A single inflow/outflow structure will be required for each of the following mining phases: IC, 3, 4B, 4C, 5A, 5B, and 5C. Each inflow/outflow structure will be a native grass -lined trapezoidal channel excavated to a depth of two feet with 4:1 (horizontal:vertical) side slopes. Because flow can be bi-directional, these channels are to be constructed with no longitudinal slope. Each channel is approximately 200 feet in length with the exception of the channel for Phase 4B which is approximately 300 feet in length. The bottom width of the trapezoidal channel will vary from 20 to 100 feet depending on the size of the phase. Phases 1C, 3, 5A, and 5C require a bottom width of 20 feet while Phases 4B and 5B require a bottom width of 50 feet and Phase 4C requires a bottom width of 100 feet. The rate of inflow from the river will vary as the river stage rises above the invert of the inflow/outflow structure based on HEC- RAS modeling of the inflow/outflow structures. For the 200 -ft channel with a bottom width of 20 feet, the inflow would be 30 cfs, 60 cfs, and 120 cfs at river stages of 1.0 feet, 1.5 feet, and 2.0 feet above the channel invert, respectively. The 200 -ft channel with a bottom width of 50 feet would convey inflows of 60 cfs, 140 cfs, and 270 cfs at similar stages of 1.0 feet, 1.5 feet, and 2.0 feet, respectively. For the 300 -ft channel with a bottom width of 50 feet, these inflows would decrease slightly to 50 cfs, 120 cfs, and 220 cfs at similar stages of 1.0 feet, 1.5 feet, and 2.0 feet, respectively. The inflow through the 200 - ft channel with a bottom width of 100 feet would be 120 cfs, 280 cfs, and 510 cfs at stages of 1.0 feet, 1.5 feet, and 2.0 feet respectively. At these inflow rates, the cells will fill from the normal water line to the invert of the inflow/outflow channel in approximately 5 to 14 hours at a river stage of 1.0 foot above the channel invert. Fill time decreases to 3 to 6 hours with the stage at 1.5 feet above the channel invert and further decreases to 1 to 3 hours at 2.0 feet above the channel invert. Based on the 2003 floodplain study of the Cache la Poudre River by the Corps of Engineers, these inflow/outflow channels will convey flood flows into the cells more frequent that a 10 -year event and possibly more frequent than a 5 -year event. Inflows to the mined cells will be conveyed through the grass -lined channels at non -erosive velocities less than 5 feet per second. In the vicinity of the mined cell, higher velocities would be expected as the inflow runs down the 4:1 side slope of the reclaimed cell. Slope protection such as a turf reinforcement mat or an articulating concrete block revetment is recommended to protect the rundown portion of these reclaimed slopes. Final design of this slope protection will be prepared prior to construction.
