SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 11 EXHIBIT D - MINING PLAN (a) Description of the method(s) of mining to be employed in each stage of the operation as related to any surface disturbance on affected lands; Overburden will be stripped and stockpiled exposing the saleable material. Dewatering trenches will be excavated down to groundwater to control on-site water levels. Once water levels are controlled allowing heavy equipment to operate, the material will be excavated down to bedrock. Groundwater recovered in the dewatering ditch will be discharged in accordance with a Colorado Discharge Permit System/NPDES regulations. (b) Earthmoving; Overburden will be stripped with scrapers or bulldozers and stockpiled to the south as mining proceeds from north to south. Excavators, front-end loaders, and bulldozers will be used to mine and stockpile the saleable material. Conveyor belts will be utilized to move the stockpiles — from north to the processing area. The mining face will be nearly vertical to 0.5:1 slope. (c) All water diversions and impoundments; and Dewatering trenches surrounding the upstream side (inside) of the pit will control water levels and diversion pumps will deliver water to a sump (low lying area) and then pumps will divert this water back to existing water courses via existing right-of-way. Settling ponds (located in the processing area) exposing groundwater will be used to wash the aggregate. (d) The size of area(s) to be worked at any one time. The maximum area to be mined at one time is approximately 20 to 25 acres. (e) An approximate timetable to describe the mining operation. The timetable is for the purpose of establishing the relationship between mining and reclamation during the different phases of a mining operation. — The Operator anticipates extracting between one million and two million tons of aggregate per year, however, production rate may vary based on market demands. Reclamation will likely begin two years after mining is complete in each phase. (t) Use Mining Plan Map in conjunction with narrative to present: I. Nature, depth and thickness of the deposit and thickness and type of overburden to be removed Overburden Silty Sand: The overburden silty sand is an eolian (wind deposited)soil and occurs near surface across the entire site as a thin layer, of approximately 5 feet thick. The SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 12 silty sand is generally loose to medium dense, dry to moist, light brown, with sand and fines (silt and clay), and is generally non-plastic. Sand and Gravel: The sand and gravel is present everywhere on the site overlying the bedrock. The sand and gravel is an alluvial deposit that ranges in thickness from • approximately 30 feet to 50 feet, averaging approximately 40 feet. This deposit ranges from gravelly sand to sandy gravel and is generally medium dense to very dense. The sands are relatively clean with fines content(silt and clay) generally less than 10 percent. Lenses of clay ("mud lenses") and fine sand were encountered in some of the borings mostly along the southern portions of the site. The bulk of the on-site alluvial sand and gravel will be excavated, processed, and sold as aggregate products. II. Nature of the stratum immediately beneath the material to be mined in sedimentary deposits Claystone: Bedrock was encountered across the site at depths ranging from approximately 35 feet to 55 feet. The bedrock surface is fairly irregular across the site, ranging in elevation from about 4,880 feet in the southwest to 4,910 feet on the northeast corner of the site. Claystone is the main bedrock facies that was encountered underlying the alluvial sand and gravel. The claystone is locally silty and sandy with minor lignite zones. The claystone is generally very hard, moderately to highly plastic, moist to very moist, and is probably part of the Denver/Arapahoe Formations. The claystone has an average in-situ dry density and moisture content of 118 pcf and 15 percent, respectively. The claystone has average liquid limit and plasticity indices of 50 and 34, respectively. (g) Identify the primary and secondary commodities to be mined/extracted and describe the ^ intended use. The primary commodities to be mined are sand, gravel and fill. The primary use of the extracted products is construction materials. Additional material may be imported and processed at the site. (h) Name and describe the intended use of all expected incidental products to be mined/extracted by the proposed operation, There are no expected incidental products to be mined.

Once the saleable material is excavated down to the claystone bedrock, the required bedrock material to build a clay liner will be excavated out at a 6 horizontal to 1 vertical slope. The clay will be processed and recompacted to form a clay liner (b) A comparison of the proposed post-mining land use to other land uses in the vicinity and to adopted state and local land use plans and programs. The proposed post-mining land use is compatible with the other land uses in the vicinity, which — includes farmland, industrial land, residences and other gravel operations. It is also consistent with the City of Fort Lupton's comprehensive plan. In addition, the Operator will be participating in the City's Interium Growth Management Plan, which is expected to be underway in October 2004. (c) A description of how the Reclamation Plan will be implemented to meet each applicable requirement of Section 3.1. The Operator will comply with the reclamation measures set forth in Section 3.1.5: • Grading will create a final topography that is appropriate for the water storage reservoirs. _ Grading will be performed to help control erosion and siltation of the affected lands. Backfilling and grading shall be completed as soon as feasible after the mining process. • Any drill or auger holes that are part of the mining operation shall be plugged with non- combustible material, which shall prevent harmful or polluting drainage. • Maximum slopes and slope combinations will be compatible with the configuration of surrounding conditions and selected land use. All slopes will be compatible with specified MLRB standards. Mined material to be disposed of within the affected area will be handled in such a manner so as to prevent any unauthorized release of pollutants to the surface drainage system. The Operator will comply with applicable Colorado water laws governing injury to existing water rights and with applicable state and federal water quality and dredge and fill laws and regulations. The Operator will stabilize and protect all surface areas of the affected land, including spoil piles so as to effectively control erosion. • The Operator will comply with all standards and conditions applicable to classified and unclassified groundwater. The Operator will protect the existing and "reasonably SW TKO Joint Venture, LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 14 potential"future uses of groundwater. We are in the process of applying for a well permit and are preparing a Temporary Substitute Water Supply Plan to augment evaporative losses from the ponds. The mining and reclamation plans have been designed to account for the safety and protection of wildlife on the mine site and at the processing area. Topsoil shall be removed and segregated from other spoil. Topsoil stockpiles shall be stored in places and configurations to minimize erosion and located in areas where disturbance by ongoing mining operations will be minimized. Once stockpiled, topsoil shall be re-handled as little as possible. • In those areas where revegetation is part of the reclamation plan, land shall be revegetated in a manner that establishes a diverse, effective, and long-lasting vegetative cover that is capable of self-regeneratiun without continued dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding area. The Operator will post appropriate signage at the entrance to the mine site. (d) Plans for topsoil segregation,preservation and replacement;for stabilization, compaction and grading of spoil;and for revegetation. Topsoil shall be removed and segregated from other spoil. Please refer to the Mining Plan Map in Exhibit C for general locations of stockpiles. For reclamation, topsoil will be replaced by a scraper and generally graded with a blade. Grading shall be done in a manner that controls erosion and siltation of the affected land to protect areas outside the affected land from slides and other damage. In addition, backfilling and grading shall be completed as soon as feasible after the mining process. Final grading will create a final topography that is appropriate for the final land use. For example, final grading of the reservoirs will replace material at a maximum 3:1 slope to meet the grade at the top of the banks. Topsoil will be uniformly placed and spread on areas — disturbed by the mining, above the anticipated high water line. The minimum thickness shall be to 12 inches above the surrounding finished grade. The topsoil shall be keyed to the underlying and surrounding material by the use of harrows, rollers or other equipment suitable for the purpose. In those areas where revegetation is part of the reclamation plan, the Operator will revegetate the land in such a manner so as to establish a diverse, effective, and long-lasting vegetative cover that is capable of self-regeneration without continued dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding area. Seed will be drilled and mulched. The revegetation seeding and plant list on the Reclamation Plan Map contains the preferred species of grass, forbs and shrubs to be planted, the hydraulic regime and the approximate height of the plantings. Seeding will take place once final grading and replacement of topsoil have been completed for each phase. Timing of seeding will be consistent with standard horticultural practice for dryland applications -generally between late September and the middle of April to assure SW TKO Joint Venture, LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 15 adequate moisture for germination. Additional plantings will be installed once the ponds have filled with water and will be watered by hand for the first two growing seasons. Long-term maintenance of the shoreline vegetation will be the responsibility of the landowner. (e) A plan or schedule indicating how and when reclamation will be implemented. Include: I. An estimate of the periods of time which will be required for the various stages or phases of reclamation. It is anticipated that approximately 20 to 25 acres will be mined annually. Reclamation activities will be conducted as mining progresses south, Reclamation will begin approximately 2 years after mining of a specific pod has started and take approximately one year to reclaim each pod to form the respective reservoirs. Therefore, reclamation will take approximately 15 to 20 years to complete. Please note that the schedule is an estimate based on current market conditions. The timing may vary depending upon the demand for construction material, which may impact the life of the mining operation. IL. A description of the size and location of each area to be reclaimed during each phase. Once half of each pod has been mined reclamation will proceed. This will continue until the compacted clay liner is built. Ill. Outlining the sequence in which each stage or phase of reclamation will be carried out. The compacted clay liner will be built in three stages: 1) The area to receive (mine high wall) the clay liner will be cleaned and scarified. 2) The borrow source (claystone)will be mined out and processed. 3) The liner will be built in lifts to finished grades. (0 A description of I. Final grading—maximum anticipated slope gradient or expected ranges thereof;; The finished slopes of the compacted clay liner will be a minimum of 3.5 horizontal to 1 vertical. The borrow area and finished grade of the borrow area will be mined out and left at the grade of 6 horizontal to 1 vertical. ii. Seeding—types, mixtures, quantities and time of application; Please refer to the Reclamation Plan Map for the list of plant materials and seeds to be utilized. The operator will seed during the appropriate season to ensure adequate moisture for germination and implement weed controls to allow the grasses to successfully establish. Additional plantings may be installed once the reservoirs are full of water and the grasses are established. SW TKO Joint Venture, LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 16 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. • The area will be mulched, as stated in the reclamation cost estimate and recommended by the Soil Conservation Service, with 4000#/acre of grass hay or straw. • Weed control practices will be implemented as required. The above procedures may be modified as conditions dictate. iii. Fertilization—types, mixtures, quantities, and time of application; The type and application rate of fertilizer shall be determined based on a soil test at the time of final reclamation. iv. Revegetation—types of trees, shrubs, etc.; Please refer to the Reclamation Plan Map for the types, quantities and location of trees and shrubs to be planted. v. Topsoiling—specify anticipated minimum depth or range of depths for those areas where topsoil will be replaced. Topsoil will be uniformly placed and spread on all areas disturbed by the mining above the anticipated high water line. The minimum thickness shall be 12 inches above the surrounding finished grade. vi. Weed control-the stockpiles will be broadcast seeded, and will be incorporated into our weed control program. Weed control consists of monthly inspections and, if necessary, chemical treatments in the applicable fall and spring seasons. 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.

(b) Identify All known aquifers Shallow alluvial aquifer. (c) Show how water from dewatering operations or runoff from disturbed areas,piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater both during and after the operation. Refer to the Mining Plan Map, Sheet 2. Mine areas will drain internally. Uncontrolled releases of surface water and sediment will not occur. Stormwater collected in the open pit will be managed in accordance with a stormwater management plan and Colorado Discharge Permit System requirements. (d) Estimate project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. Approximately 24.1 acres of exposed water surface from dewatering trenches and settling ponds will cause 71.4 acre-feet per year of evaporative losses. Assuming a production rate of 1.5 million tons per year, approximately 44.1 acre-feet per year of water will be lost as a result of mining aggregate. Batching 150,000 yd3 of concrete will use up 15.5 acre-feet of water per year and approximately 2 acre-feet of water per year will be used for dust control. The water needed to supply the site requirements stated above will come from on-site water pumped from the proposed settling ponds and dewatering trenches. This water will then be replaced by leasing reuseable effluent from a municipality or by utilizing consumptive use credit(HCU) from historic diversions made by on-site irrigation ditches. A Temporary Substitute Water Supply Plan (TSSP) will be created to more closely analyze the timing and location of the depletions. This plan will be renewed either every two years or whenever the replacement water lease is at term. (e) Indicate the projected amounts of the water sources to supply project water requirements The required volume of water will be either; 1) leased from an upstream municipality and released to the river according to the specified timing per the TSSP to ensure no injury to downstream water users or, 2) historic consumptive use credit will be utilized. If HCU credit is used, it will require that wintertime replacements are made by leasing effluent from a municipality. The amounts of replacement water will vary if the HCU credit is used due to the sw TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 19 smaller amount of water required to make replacements because the HCU credit will offset the depletions from mining. (t) Affirmatively state that the Applicant has acquired or applied for a National Pollutant Discharge Elimination System permit from the Water Quality Control Division The Operator will apply for a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division of the Colorado Department of Public Health and Environment prior to discharging water from the site.

INTRODUCTION This report constitutes Exhibit H— Wildlife Information, in fulfillment of the Colorado Division of Mining and Geology(DMG) requirements for a permit to mine sand and gravel (Section 6.4.8, Construction Materials Rule 6). The report was prepared on behalf of Civil Resources, LLC, project planners and engineers, by Walsh Environmental Scientists and Engineers, LLC (Walsh Environmental)of Boulder, Colorado. Information presented in this report is based on a site survey in early July 2004 and information available online from the Colorado Division of Wildlife(CDOW) Wildlife Resource Information System (WRIS) database for Weld County. The site survey and review of existing information was performed by Allen B. Crockett, Ph.D., Certified Wildlife Biologist and Senior Ecologist with Walsh Environmental). The site is located east of U.S. Highway 85, west of Weld County Road 27, and north of Weld County Road 6. The northern boundary lies approximately 3,000 feet north of Weld County Road 8. (a) SIGNIFICANT WILDLIFE RESOURCES ON THE AFFECTED LAND Results of the site survey indicate that the affected land does not support significant wildlife resources. This finding is based on the fact that the site consists almost entirely of agricultural lands (primarily vegetable crops)that provide very limited and low-quality wildlife habitat. Although the croplands are nearly devoid of wildlife value, some areas along the margins of the proposed sand and gravel mining operations provide some habitat for common farmland species. These areas are located primarily in the degraded pasture and small wetland in the northwestern portion of the site adjacent to U.S. 85 and around rural residences along the eastern edge of the site adjacent to Weld County Road 27. Because of the obviously poor overall habitat quality for wildlife, particular attention was given during the surveys to the use of the few mature trees for nesting by birds of prey (raptors) and use of the irrigation ditches by wetland or riparian species. Results are summarized below. Mammals Due to the general lack of cover and either forage for herbivores or prey for carnivores, the site does not support significant mammalian resources other than small rodent species. An occasional vagrant mule deer or white-tailed deer could move onto the site from the South Platte River corridor to the west, but the wide and heavily traveled condition of U.S. 85 would limit such use, as would the nearly total lack of suitable habitat. If deer were to occur, the only area offering some habitat is the degraded pasture immediately east of the highway in the northwestern part of the site. Carnivores potentially present include the ubiquitous red fox and coyote, although these species would also be limited by the lack of natural habitats within the intensively farmed area. Either species could move along the irrigation ditches or into the degraded pasture area in search of prey, but prey abundances are likely very low. Two more omnivorous species, the raccoon and striped skunk, almost certainly occur throughout most of the site, although primarily along the few ditches and northwestern area. SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 21 Small mammals potentially present include the fox squirrel and cottontail rabbit(eastern cottontail and desert cottontail) in small areas of trees around rural residences. Otherwise, mammals are mostly limited to bats (e.g., big brown bat, little brown bat) nesting in the few large trees or common rodents along unmown margins of ditches or in the degraded pasture area. Examples of the latter include the deer mouse, western harvest mouse, meadow vole, and house mouse. Birds A variety of common farmland species of birds, including both residents and migrants, are likely to use the few trees, small pasture and wetland area, and ditch margins for nesting or feeding. These species are described by habitat type below: Scattered Trees The few scattered individuals or small clumps of mature trees have the potential to support nesting or diurnal perching by common raptors such as the American kestrel, Swainson's hawk, red-tailed hawk, and great homed owl. However, the potential for use by raptors is greatly limited by three factors: • The large trees occur on the fringes of the site, adjacent to busy roads(including U.S. 85)or human residences. ■ The adjacent lands consist almost entirely of intensively cultivated croplands, which provide virtually no preybase for raptors. • Much more numerous nesting or perching sites occur along the South Platte River, which lies as little as 0.25 mile from the site. In addition to the more abundant trees nearby, the riverine trees offsite offer more solitude and greater proximity to hunting habitat for the raptors than any of the trees onsite. Although all of the raptors named above are known to nest and hunt in proximity to highways and human dwellings, the last point above—proximity to the South Platte riparian corridor—makes any use much less likely than if the onsite trees were the only suitable trees in the general vicinity. Besides limited potential habitat for raptors, the trees also provide little habitat for other birds of special concern in the region, such as Neotropical migrant songbirds. Any use of the trees is mostly limited to migrant or resident birds commonly associated with farmland and rural residential areas. Examples include the northern flicker, black-billed magpie, blue jay, black-capped chickadee, American robin, Brewer's blackbird, common grackle, and house finch, and a non-native species, the European starling. Possible migrants using the trees for nesting include the eastern kingbird, western kingbird,American robin, yellow warbler, Bullock's oriole, American goldfinch, and lesser goldfinch. While it is possible that an uncommon species could stop briefly in one of the scattered trees or clumps to rest or forage during migration, the potential for such use is extremely unlikely due to the poor habitat and proximity to the South Platte River. SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 22 Irrigation Ditches Irrigation ditches that flow through or adjacent to the site do not provide riparian habitat(i.e., similar to that along a stream). While some regional ditches support a narrow riparian of cottonwood or other trees and an understory of willows or other shrubs, the onsite ditches lack such habitat. Instead, they consist of a narrow zone of herbaceous plants(mostly non-native pasture grasses and common ruderal forbs [weeds]) on banks and tops of the berms. These zones of relatively rank(i.e., unmanicured)vegetation are typically only a few feet wide—with a maximum of perhaps 20 feet—and grade abruptly to irrigated cropland or ^ pastureland. Use of the ditches by birds is probably limited to feeding on seeds or insects by the tree-nesting species mentioned above, as well as ground-nesting species such as the western meadowlark and lark sparrow. They may also provide limited cover and movement routes for another rural species, the ring-necked pheasant. The small wetland adjacent to U.S. 85 in the northwestern part of the site did not support wetland species at the time of the site survey in mid-July 2004. Species potentially present there include the red-winged blackbird, common yellowthroat(a warbler), and song sparrow. However, the small size of the habitat may make it too small for nesting by any of these species. Farm Buildings In addition to the adjacent trees, farm structures also provide habitat for some birds such as the rock dove (pigeon), European starling, and house sparrow(all of which are non-native) and migrants such as the Say's phoebe, barn swallow, and cliff swallow(all of which may nest beneath eaves or in rafters). ^ Reptiles,Amphibians, and Aquatic Species The lack of significant natural habitat and of surface water greatly limits the potential for use by these vertebrate groups. The irrigation ditches does not provide habitat for fish or aquatic life, except potentially for some aquatic insects with highly mobile adult stages, or for amphibious species such as frogs and toads. The small wetland in the northwestern area does provide limited habitat for three common amphibians: the northern chorus frog, Woodhouse's toad, and plains spadefoot(toad). It is not know whether these species occur in the wetland, but none is considered rare. Reptiles onsite would be expected to include the western terrestrial garter snake and, potentially, the plains garter snake around the small wetland, in the small-degraded pasture area, around rural residences, and along unmown ditch margins. Snakes and lizards commonly associated with grasslands (e.g., bull snake, yellow-bellied racer) are also not likely to occur onsite due to the very small size and degraded condition of the only pasture habitat, adjacent to U.S. 85. (B) Seasonal Use of the Area Because of its location far from the base of the Front Range foothills, lack of significant native habitat (including woodlands or grasslands), and lack of aquatic habitat, the site mostly supports resident species commonly associated with agricultural and rural residential areas. Seasonal use is therefore limited to the small number of birds that nest in the scattered trees or eaves of rural residences along the eastern edge of the site or in the degraded pasture in the northwestern portion. These species are discussed above. In addition to year-round use by resident birds and nesting use by summer migrants, the site provides some habitat for winter migrants. The most abundant winter residents likely to occur onsite are the horned SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 23 lark in the degraded pasture or fallow fields and the tree sparrow in unmown areas of tall, weedy vegetation along the ditches. Use by migrants such as waterfowl (ducks and geese), wading birds (herons), and shorebirds (plovers and sandpipers) is essentially negated by the lack of suitable aquatic habitats. Gulls could use the fields in spring or fall migrations. Of the potential nesting raptors described in subsection (a), the red-tailed hawk and great homed owl are present year-round, while the Swainson's hawk and American kestrel are migrants. The rough-legged hawk is present only in winter but is unlikely to occur onsite due to the near lack of grassland habitat. (c) THREATENED OR ENDANGERED SPECIES _ The discussions below regarding threatened, endangered, or Colorado special-concern species are limited to species potentially present in the site vicinity, although not in the types of habitats present onsite. Threatened, Endangered, or Candidate Species Preble's Meadow Jumping Mouse(Zapus hudsonius prebletl—This federally listed threatened mammal occurs along streams and ditches supporting riparian habitats in portions of the Front Range region of Colorado, including the Fort Lupton vicinity. However, the site lacks suitable habitat, and this species is therefore not expected to occur. Bald Eagle (Haliaeetus leucocephalus)—This federally listed threatened raptor has been proposed for removal from the federal list but remains on the list at this time. Bald eagles occur in the Fort Lupton area during all seasons, but primarily in winter and during migrations. The species has nested at Barr Lake in recent years and is beginning to nest more broadly, including the South Platte River corridor. The potential for use of the site by the bald eagle is very limited by the poor habitat quality, lack of prey, and proximity to the much superior habitat along the South Platte River. Burrowing Owl (Athene cunnicularia)—This small owl is state-listed as threatened in Colorado. It is closely tied to prairie dog towns, where it uses abandoned burrows for nesting and roosting. The absence of prairie dogs onsite (see below)essentially negates the potential for occurrence by this species. Colorado Special-Concern Species Black-tailed Prairie Dog (Cvnomvs ludovicianus)—This federal candidate and Colorado special-concern species was previously proposed for listing, and USFWS concluded that listing was "warranted but precluded." Abandoned prairie dog burrows are used for nesting by the burrowing owl, a state-listed threatened species in Colorado (see below). No prairie dog colonies occur onsite, and the intensive agricultural lands do not provide suitable habitat. Swift Fox (Vulpes velox)—This carnivore occurs in the eastern plains of Colorado, where it is mostly limited to shortgrass prairie. The lack of such habitat onsite and intensive agricultural use essentially negate the potential for occurrence by this species. Mountain Plover(Charadrius montanus)—This federal candidate and Colorado special-concern species _ occurs in shortgrass prairie, of which none is present onsite. Prairie dog towns sometimes attract this bird but, again, no prairie dogs occur onsite. SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 24 Ferruginous Hawk (Buteo regalis)—This prairie-dwelling buteo occurs year-round in the project region. However, the absence of grassland habitat and prairie dogs onsite makes use by this species very unlikely. Common Garter Snake(Thamnophis sirtalis)—This species is limited to lush grasslands, mostly along drainages. While it probably occurs along the South Platte River, it is unlikely to occur in the poor-quality and limited habitat along the irrigation ditches and small wetland onsite. Northern Leopard Frog (Rana pipiens)—This amphibian occurs in areas of permanent surface water in the project region. Therefore, the lack of surface water other than the unsuitable(fast-flowing, highly seasonal) irrigation ditches negates the potential for occurrence by this species. (d) GENERAL EFFECT OF PROJECT ON EXISTING WILDLIFE The proposed sand and gravel mining operations will not have significant adverse impacts on wildlife, either onsite or offsite. This conclusion is based on the following considerations. Temporary and Permanent Loss of Food and Habitat Because the site is almost entirely agricultural cropland, with only a small area of degraded pasture, a very small wetland area, and scattered individuals or small groups of trees primarily around houses and other buildings, it provides minimal area and quality of wildlife habitat. Following mining, the reclaimed areas will consist of open water bodies, which will probably have greater ecological value than the existing croplands. While some trees will be lost, those along the eastern edge of the site north of Weld County Road 8 will probably be preserved, although (as at present)will be of minimal value due to the proximity to County Road 27. Besides being of minimal value for onsite species, the area does not provide significant habitat for offsite species, again owing to the intensive agricultural use. The small areas of habitat provided by the degraded pasture, wetland area, and ornamental trees are currently used almost exclusively by onsite species because they are of insufficient size or quality to attract wildlife from offsite areas. Interference with Migratory Routes The proposed sand and gravel mining operations would not interfere with annual, seasonal, or daily migration routes or movement corridors due to the very minor extent and quality of habitat associated with the croplands, degraded pasture, small wetland, and ornamental trees and shrubs. While the South Platte River corridor west of the site supports abundant and diverse wildlife, no habitats occur east of the site that would support regular movement through or across the proposed mining area. Effects of Increased Human Activity, Including Noise Because areas surrounding the proposed mining operations are very marginal for wildlife, disturbance associated with mining operations, increased vehicular traffic, and other activities would not be expected to impact offsite species—and no substantial onsite wildlife use currently occurs. Of special potential concern is the impact of mining on wildlife use and movement along South Platte River corridor. While the mining operations would be less than 0.25 mile from the river in some areas, the increased human activity and noise would not be expected to affect riverine species. This conclusion is based on the following: • The proposed mining area is already an area of intensive human use, including mechanized agriculture. SW TKO Joint Venture, LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 25 • Adjacent areas east of U.S. 85 are also intensively used by humans for agriculture and other purposes, including equipment and materials storage and high-density residential occupancy(mobile home park). • U.S. 85 is a heavily traveled highway between the site and the South Platte. • Nearby areas west of U.S. 85, adjacent to the river, also support intensive human activity, and existing sand and gravel mining occurs along nearby river segments. For these reasons, it is reasonable to conclude that any species vulnerable to high levels of human activity and noise, such as would be associated with mining, are already absent from otherwise suitable onsite or offsite habitats or have habituated to the human activity and would be unaffected by the additional disturbance. a SW TKO Joint Venture,LW.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 26 EXHIBIT I - SOILS INFORMATION (1) In consultation with the Soil Conservation Service or other qualified person, indicate on a map(in Exhibit C) or by a statement the general type, thickness and distribution of soil over affected land.

INTRODUCTION This report constitutes Exhibit J— Vegetation Information, in fulfillment of the Colorado Division of Mining and Geology(DMG) requirements for a permit to mine sand and gravel (Section 6.4.10, Construction Materials Rule 6). The report was prepared on behalf of Civil Resources, LLC, project planners and engineers, by Walsh Environmental Scientists and Engineers, LLC (Walsh Environmental)of Boulder, Colorado. Information presented in this report is based on a site survey in early July 2004 and information available from the Colorado Natural Heritage Program (CNHP)database for Weld County. The site survey and review of existing information was performed by Allen B. Crockett, Ph.D., Senior Ecologist with Walsh Environmental). The site is located east of U.S. Highway 85, west of Weld County Road 27, and north of Weld County Road 6. The northern boundary lies approximately 3,000 feet north of Weld County Road 8. (a) PRESENT VEGETATION TYPES Agricultural Cropland The site currently consists almost entirely of agricultural land used primarily for the production of vegetable crops. At the time of the survey in July 2004, some of the lands were in active production, while others were lying fallow as part of normal crop rotation. In addition to the planted crops, these lands support some common agricultural weeds (e.g., field bindweed, kochia, goosefoot, prickly lettuce, annual sunflower), especially along field margins or in fallow areas. Irrigation Ditches The site contains multiple irrigation ditches that provide water for the intensive agricultural uses onsite and convey water to other downstream users. The ditches are essentially devoid of riparian trees and shrubs or herbaceous wetland plants. Most of the ditch margins are weedy and unmown and therefore support relatively rank vegetation. Foliar cover on the banks is high (more than 80 percent)due to the height of the weedy growth (2 to 4 feet high). Prevalent species include kochia, goosefoot, prickly lettuce, and giant ragweed. More floriferous species such as common tansy, tall goldenrod, and common evening-primrose are also present along the ditches. Degraded Pasture • Immediately east of U.S. 85 in the northwestern part of the site is an area of approximately 16 acres that — supports a degraded pasture. The pasture consists primarily of introduced pasture grasses (predominantly smooth brome) with associated ruderal forbs such as annual sunflower, common dandelion, field bindweed, English plantain, and Dutch white clover. The pasture is grazed, with the result of low height(less than 12 inches) except for some weeds (e.g., kochia, goosefoot, prickly lettuce) along the fenceline. Foliar cover of perennial grasses is 70 percent or greater due to dominance by aggressive rhizomatous pasture species and relatively moist conditions in the low-lying area. Forbs (mostly annual or biennial) add another 10 percent foliar cover. SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 28 A few native trees, including approximately six plains cottonwoods and five peachleaf willows, occur at the margins of the pasture. Wetland The northern end of the degraded pasture immediately east of U.S. 85 supports a small wetland less than 1 acre in size. The wetland appears to be related to impediment of surface and shallow subsurface flows in the low-lying area,supplemented by ditch seepage. Although small, the wetland is complex, with areas dominated by coyote willow in the southern part and by cattails and other herbaceous species in the northern part. A small number of peachleaf willow trees punctuate the wetland area. Associated wetland species include softstem bulrush and Olney bulrush along the cattail margins, grading through a zone of Baltic rush, Nebraska sedge, and Emory sedge to adjacent pasture grasses. Prominent forbs in the outer margins of the wetland include showy milkweed, scarlet milkweed, curly dock, and lady's-thumb. Weedy species such as Canada thistle and wild teasel are also present, representing about 5 percent of the community. Foliar cover in the wetland is more than 100 percent due to dense growth and overlapping canopies. Estimates of cover by lifeform across the wetland as a whole are as follows: trees (peachleaf willow)—5 percent, up to 15 feet high;shrubs(coyote willow)—40 percent, up to 7 feet high;wetland graminoids (including cattail, bulrush, rushes, and sedges)—40 percent, typically 1.5 to 4.5 feet high; and wetland forbs— 15 percent, mostly 1 to 3 feet high. Impacts to this wetland may require authorization from the U.S.Army Corps of Engineers pursuant to Section 404 of the Clean Water Act. Dry Terrace Slope Separating the croplands from a degraded pasture and wetland to the west is a steep terrace slope extends north-south through the northwestern part of the site. In the southern part, the terrace slope is west of U.S. 85 and not onsite. The slope itself is not farmed but shows the effects of prior grazing and perhaps other ground-disturbing activities. Vegetation is dominated by non-native pasture grasses (e.g., smooth brome) with some native grasses such as blue grama, sand dropseed, thickspike wheatgrass, and purple three- awn and a variety of forbs. The latter include native species such as hairy golden-aster and curlycup gumweed as well as various weedy non-natives. Farm Trees and Landscape Trees and Shrubs Trees and shrubs are not a prevalent part of the site vegetation. Indeed, the only"naturally occurring"trees are perhaps a dozen plains cottonwoods and half that many peachleaf willows scattered throughout the site, mostly on field margins or in the degraded pasture and wetland areas described above. However, introduced (planted) trees and ornamental shrubs are a conspicuous part of the landscape at existing rural residences and an old school house, mostly on the eastern edge of the site adjoining County Road 27. Species observed during the survey in July 2004 included blue spruce, Rocky Mountain juniper (red cedar), plains cottonwood, European white poplar, Siberian elm, hackberry, green ash, and walnut. Russian-olives are also present in these settings, as are lilac, spirea, and other ornamental shrubs and flowering fruit trees. The total number of planted trees on the site margins was not counted precisely but is estimated at fewer than fifty. SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 29 (b) RELATIONSHIP OF PRESENT VEGETATION TO SOIL TYPES Croplands, Irrigation Ditches, Farm Trees, and Landscape Trees and Shrubs Most of the proposed sand and gravel mining area has been mapped by the Natural Resources Conservation Service (formerly the Soil Conservation Service) as Altvan Loam, 0 to 1 percent slopes. This is described as a deep, well-drained soil on terraces at elevations from 4,500 top 4,900 feet. Permeability and available water capacity are moderate, surface runoff is slow, and erosion hazard is low. The eastern edge of the proposed mining area is mapped as Dacono clay loam 0 to 1 percent slopes. This is also described as a deep, well-drained soil on terraces, at elevations of 4,550 to 4,970 feet. Permeability is moderately low, available water capacity is moderate, and erosion hazard is low. Degraded Pasture and Wetland The degraded pasture and small wetland east of U.S. 85 in the northwestern corner of the site are mostly within Aquolls and Aquents, gravelly substrate. This mapping unit occurs on bottomlands and floodplains of major streams, including the South Platte River. They are deep, poorly drained soils that are subject to — flooding, with protracted portions of the growing season being saturated at or near the soil surface. ^ Terrace Slope Separating the low-lying pasture and wetland from the higher terraces is a terrace slope mapped as Ustic Torriorthents, moderately steep. These are described as deep, excessively drained (i.e.,droughty)soils on terrace breaks and escarpments at 4,450 to 5,100 feet. Permeability is rapid, available water capacity is low, surface runoff is medium, and erosion hazard is moderate. This slope onsite is steep and west-facing and supports a narrow ribbon of dry, weedy vegetation that has not been farmed but has been impacted by grazing or other prior disturbance. (c) Annual Production and Croplands Because the post-mining land use of the mining area consists of open-water reservoirs, information on average annual production of existing hay meadows and croplands was not collected. SW TKO Joint Venture,LLC.—Adams Sand and Gravel Mine—112 Reclamation Permit Amendment Page 30 EXHIBIT K — CLIMATE INFORMATION This property is in a semi-arid continental climate strongly influenced by the Rocky Mountains. The area is usually warm in the summer with frequent hot days. In winter, periods of very cold weather are caused by artic air moving in from the north or northwest. Milder periods occur when westerly winds are warmed as they move down slope off of the mountains to the west. Weather monitoring data is not available from the site. The nearest weather monitoring station is the Western Regional Climate Center weather station at Brighton (elev. 4976)/Fort Lupton (elev. 4904) CO. According to data from the Western Regional Climate Center weather station the average total annual precipitation is 13.0 inches. Most of the precipitation occurs as rainfall during the warmer part of the year with the heaviest rainfalls in the late spring and early summer. Winter snowfall is frequent but the snowcover usually melts quickly during the milder periods. The average annual temperature is 49.65° F.•' �' RE Y .v. 6.S ..u4Rt.

This will occur during phase 4. We have assumed that Phase 1 and 2 will be fully reclaimed and Phase 3 will be half reclaimed. Final grading and placement of the compacted clay liner and miscellaneous close out will be required for Phase 3. The processing area and all equipment associated with the processing area will have to removed along with cleanup of the processing area.

This letter describes the project and slope stability calculations carried out to evaluate the minimum distance between the edge of mining and adjacent structures to avoid damage to the structure. The site is located approximately one-eighth mile east of the South Platte River(composed of the Villano, Sasaki, Adams,Watada,Yokooji,and Wiant properties). The site is within parts of Sections 18 and 19 of Township 1 North, Range 66 West of the 6th Principal Meridian. The site is generally bounded on the west by U.S.Highway 85,WCR 6 on the south, and the Fulton Ditch lateral and WCR 27 to the east. The project is located in Weld County, Colorado,as shown on Figure 1. Approximately three feet of overburden is underlain by a relatively deep alluvial aggregate deposit, probably to be mined by LaFarge, Inc. The aggregate will likely be transported via conveyor to a processing plant located west of Highway 85 on the existing Lafarge property. This report lists minimum safe setbacks for mining from structures within 200 feet of the permitted boundary based on stability calculations. Actual setbacks may be greater due to permit limitations,zoning requirements,construction issues, agreements with owners,extent of economically mineable aggregate,or other issues. GEOLOGY The site is located approximately 30 miles east of the foothills of the Colorado Front Range on the western flank of the Denver Structural Basin. The basin is a downwarp of sedimentary strata that trends north-northwest, parallel to the mountain front. In the project area,the sedimentary beds dip gently eastward toward the axis of the basin east of the site. Based on regional geologic mapping(Colton, 1978),the near surface bedrock in the project area is the Paleocene and Upper Cretaceous Denver and Arapahoe Formations. The bedrock is overlain by upper Pleistocene and Holocene (Quaternary age)gravel deposits and eolian(wind blown)overburden soils. The gravel deposits exist primarily within the Broadway Alluvium deposit. The bedrock unit consists mainly of claystone and may contain lenses of siltstone and sandstone. GEOTECHNICAL CONDITIONS Subsurface data from earlier aggregate investigations and Civil Resource's geotechnical investigation have been compiled, reviewed, and analyzed. Investigations were completed at the site by the following consultants: - 451 OAK STREET, SUITE 209 • P.O.

September,2004. — • Civil Resources(28 geotechnical borings completed with one pumping well and 2 piezometers across all properties in September, 2004). The investigations by Ground,CTL,and Lafarge primarily focused on overburden soils and sand and gravel estimates. The previous two investigations by Civil Resources,obtained insitu claystone bedrock samples in order to obtain geotechnical index and engineering properties and were surveyed. The claystone bedrock samples were sent to Advanced Terra Testing for moisture content and density(ASTM D2216&D 2937),Atterberg limits(ASTM D4318), and — percent fines(ASTM D1140). Additional insitu bedrock samples were obtained for future strength testing(TXCUR,ASTM D4767 and TXUU ASTM D2850). The locations of all borings are shown on Figure 2. Summary logs for the Civil Resources drilling investigation are shown on Figure 3. A summary of the bedrock index properties is included on Table — 1. Laboratory test results are included in Appendix A. — The surficial geology at the site was also mapped as part of Civil Resource's studies. Geologic mapping and exploratory drilling at the site identified three major natural geologic strata. These strata consist of two soil units and one bedrock unit. The units that were identified are as follows: 1)overburden silty sands, 2)alluvial sand and gravel,and 3)claystone bedrock. These units are described more completely as follows: Overburden Silty Sand. The overburden silty sand is an eolian(wind deposited)soil and occurs near surface across _ the entire site as a thin layer,of approximately 5 feet thick. The silty sand is generally loose to medium dense,dry to moist,light brown,with sand and fines(silt and clay), and is generally non-plastic. ` Sand and Gravel: The sand and gravel is present everywhere on the site overlying the bedrock. The sand and gravel is an alluvial deposit that ranges in thickness from approximately 30 feet to 50 feet,averaging approximately 40 feet. This deposit ranges from gravelly sand to sandy gravel and is generally medium dense to very dense. The sands are — relatively clean with fines content(silt and clay)generally less than 10 percent. Lenses of clay("mud lenses")and fine sand were encountered in some of the borings mostly along the southern portions of the site. The bulk of the on-site alluvial sand and gravel will be excavated, processed, and sold as aggregate products. — Claystone: Bedrock was encountered across the site at depths ranging from approximately 35 feet to 55 feet. The bedrock surface is fairly irregular across the site, ranging in elevation from about 4,880 feet in the southwest to 4,910 feet on the northeast corner of the site. Claystone is the main bedrock facies that was encountered underlying the alluvial sand and gravel. The claystone is locally silty and sandy with minor lignite zones. The claystone is generally very hard, moderately to highly plastic, moist to very moist,and is probably part of the Denver/Arapahoe Formations. The claystone has an average in-situ dry density and moisture content of 118 pcf and 15 percent, respectively. The claystone has average liquid limit and plasticity indices of 50 and 34,respectively. A summary of geotechnical data for the claystone bedrock is included in Table 1. — Mr. Mark Campbell ( September 27, 2004 ��0 Page CIVIL RES'VURCES,LLC SITE GROUNDWATER Civil Resources has installed and surveyed seven piezometers as part of our geotechnical investigation in June,2004 at the locations shown on Figure 2. The limited data indicates a slight hydraulic gradient toward the South Platte River to the northwest The average depth to groundwater in June and July,2004 was approximately 25 feet. The piezometers will be monitored monthly in order to determine the seasonal fluctuations of the groundwater surface. STRUCTURES WITH 200 FEET OF DISTURBED AREAS The known, permanent, man-made structures within 200 feet of the proposed mine area are listed below: • Highway 85(western boundary), • WCR 27(eastern boundary), • WCR 8,south of the Villano Property&North of Sasaki&Adams Property, • WCR 6,south of the Yokooji Property, • Fulton Ditch Lateral along the east boundary, • Gas Wells(Villano&Adams Properties), • Underground gas utilities, • Overhead power utilities. EXISTING EASEMENTS It is our understanding that the following easements exist at the site: • A proposed 60-foot ROW parallels the eastern Section 19 line for future road widening for WCR 27, • A proposed 50-foot ROW parallels the northern Section 19 line for future road widening for WCR 8, • A proposed 50-foot ROW parallels the southern Section 19 line for future road widening for WCR 6, _ • An existing ROW for Highway 85 extends along the entire western property boundary, • A 15-foot telecommunication easement extends along the eastern boundary of Villano, • The existing oil well on Villano has a 50-foot gasline easement running due north of the well, • The existing oil well on Adams has a and a 50-foot easement along Highway 85,and _ • The Yokooji property has a 50-foot Panhandle Eastern Pipe Line Company easement along the northwest property line, and a 75-foot Public Service easement from the power lines on the northern margin. _ We assumed that the Fulton Ditch Lateral would maintain a prescriptive access easement of 35 feet from the ditch centerline or 15 feet from top of bank,whichever is greater. STABILITY ANALYSES The stability of the proposed mining limits was evaluated at five sections under anticipated and required loading _ conditions around the perimeter of the site,discussed below. The computer program XSTABL was used for the analysis. The method for selecting the critical failure surface for each analyzed loading condition is the following. Modified Bishop's method of analysis is used to find the critical failure surface by randomly searching with 20 termination points and 20 initiation points(400 failure circles)over a broad range of the slope surface. This procedure is repeated over different initiation and termination locations until the most critical factor of safety failure surface is identified. The range is narrowed for the final run of 400 circles to determine the lowest factor of safety. The final stability run analyzes the critical surface using the Spencer method by inputting the X and Y coordinates of the circle center and the XI location Mr. Mark Campbell ((� September 27, 2004 Page4 CIVIL RES-PURCES,LLC of the intersection of the circle with the ground surface. The Spencer method is preferred because it is able to satisfy both moment and force equilibrium, but can only analyze one surface at a time. Therefore,prior to submitting the final stability run, at least 1200 failure surfaces were analyzed to determine the lowest factor of safety. The five cross-section locations were selected to analyze stability for the mining limits under different surcharge loads and depth to bedrock conditions. The locations are described below and shown on Figure 2. ► Section A-A': This section considers the northwest portion of the Villano property that will be mined near Highway 85. A surcharge of 300 psf was included to model the live load on Highway 85. ► Section B-B': This section considers the oil well located on the Villano property. A surcharge of 500 psf was included to model the dead load from the storage tank. ► Section C-C': This section considers a deep bedrock section near Highway 85 on the western margin of the Sasaki property. A surcharge of 300 psf was included to model the live load from Highway 85. ► Section D-D': This section considers a higher phreatic surface due to full flow conditions in the Fulton Lateral and the live load from WCR 27. A surcharge of 250 psf was included to model the live load from WCR 27. ► Section E-E': This section considers a cross section along the southern margin of the Yokooji property,along WCR 6. A 250 psf surcharge was included to model the live load from WCR 6. The material index and engineering strengths assumed in this slope stability report are discussed below. Final design geotechnical investigations will further refine our knowledge of the subsurface and embankment material properties. MATERIAL PROPERTIES Overburden The index properties for the insitu overburden were based on field testing data and on our engineering judgment;the following parameters have been used to model the overburden. Dry Unit Moist Unit Saturated Unit Cohesion C'psf Friction Angle V° Weight(pct) Weight(pct) Weight(pct) 103 117 121 0 35 Alluvial Sand and Gravel The sand and gravel is generally medium grained sand, medium dense, poorly to well graded, and generally clean. The deposit ranges from fine to coarse sand with some silt and occasional rounded to well rounded gravels less than 2- inches in diameter. The alluvial sand and gravel has been modeled as follows: Dry Unit Moist Unit Saturated Unit Cohesion C'psf Friction Angle V° Weight(pcf) Weight(pct) Weight(pct) 119 129 129 0 38 Mr. Mark Campbell CO O September 27,2004— Pages CIVIL RES7JURCES,LLC _ Claystone Bedrock — The proposed mine area is generally underlain by claystone bedrock. Claystone is generally a weak bedrock and is often prone to slope instability and the bedrock foundation strength is critical for the highwall stability. For the claystone bedrock,two potential strength conditions were considered. These strength conditions are referred to as: 1)peak — strength,and 2)residual strength. Peak strength is the maximum shear strength the claystone bedrock exhibits. The shear strength is made up of both cohesion(diagenetic bonding)and internal friction. Under short-term conditions for unsheared claystone,peak strength — governs behavior. If a sheared surface or sheared zone is present within claystone as a result of faulting,slippage between beds due to folding,past shrink-swell behavior,stress relief,or from a landslide,the cohesion along the _ sheared surface is reduced to zero,and the angle of internal friction is decreased,due to alignment of clay minerals — parallel to the shear plane. Under these conditions a claystone exhibits its lowest strength known as residual strength. _ Residual strength bedrock occurs in discrete zones, parallel with the sheared surface or zone,whereas fully softened strength occurs over a broader area. The engineering and index properties of the bedrock used for the stability analyses are shown in Table 1. Based on data from other recent jobs,and engineering judgment,we modeled the claystone as follows: Dry Unit Moist Unit Saturated Unit Friction Angle 0'° — Weight(pct) Weight(pct) Weight(pct) Cohesion C'psf — 116 119 123 Peak=500 Peak=26 Residual=0 Residual= 15 STABILITY ANALYSES RESULTS - Setbacks listed in Table 2 indicate the minimal setback from the structure to the mining limits. The setback distance can be increased as needed to address other restrictions.

As a result,we propose the following locations for the extent of mining offsets inside of the property boundary.

Page 6 CIVIL RES'7)URCES,LLC LIMITATIONS Our review is based on regional geologic mapping, present mining plans, borehole data,and stability analyses using typical strength parameters for the various strata in the critical sections. Should the mining plans change or subsurface — conditions vary from those portrayed in this letter,we should be contacted in order to re-evaluate the potential affects on permanent man-made structures. Stability analyses were run at the structure in question and were not run on failure surfaces closer to the highwall. Factors of Safety at and closer to the highwall will be less than those calculated at the permanent man made structures. Note also that surcharge loads due to temporary material stockpiles and overburden berms were not considered in the analysis.
