INTRODUCTION Cooley Gravel Company (Cooley) proposes to develop a surface sand and gravel mining operation with appurtenant asphalt and concrete batch plants on approximately 213 acres of land in Weld County. The property is located near Rinn,just north of County Road 20.5, east of Boulder Creek, and approximately six miles east-southeast of Longmont, Colorado. This document was prepared by Haley & Aldrich, Inc. on behalf of Cooley as application to the State of Colorado Division of Minerals and Geology (DMG) for a Regular (112) Mining and Reclamation Permit, and to the Weld County Planning Commission and Board of County Commissioners for a Use By Special Review Mining Permit. The site is currently used as rangeland for cattle and is partially irrigated by water from the Smith and Emmons Ditch. The site is entirely within the 100-year floodplain. A wildlife assessment revealed no threatened or endangered species, nor any critical wildlife habitat. Present vegetation consists of pasture grasses with cottonwood trees along Boulder Creek. A wetlands delineation identified jurisdictional wetlands only along a narrow corridor along Boulder Creek and these will be protected by a riparian buffer zone that will not be mined. Cooley proposes to mine the property in four phases during approximately 15 to 20 years. The proposed mining will consist of dry mining with dewatering via perimeter trenches or wet mining with a dragline. The site contains approximately 15 to 20 feet of alluvium and topsoil soils overlying clay shale bedrock which acts as an aquitard between the alluvial aquifer and deeper bedrock aquifers. A partial, optional, slurry wall has been considered to limit ground water inflows to the operation and to protect adjacent water resources, if necessary. No negative impacts to Boulder Creek are anticipated. Proposed reclamation will consist of either an open lake or a sealed water storage reservoir, both with irregular, revegetated shorelines to blend with the surrounding land use. The open lake option will entail ground water depletions via evaporation which will be augmented. The sealed water storage reservoir option will require construction of a slurry wall surrounding the site to separate ground water from stored water. Reclamation will be concurrent with mining and will include revegetation 1 with native grasses on shorelines and with cottonwood trees on approximately 40-foot centers along Boulder Creek. Slopes have been designed to minimize erosion. Cooley intends to obtain appropriate DMG and County permits prior to initiating operations. In addition, an NPDES discharge permit will be obtained prior to dewatering. No U.S. Army Corps of Engineers Dredge and Fill (404) permit will be required. Colorado Department of Health air permits for fugitive dust and plant operations will be obtained in accordance with regulatory requirements. The remainder of this document provides detailed information about the site, the proposed mining operation, the reclamation plan and costs, and other relevant site information required by DMG and the County. 2 II.

EXHIBIT C - PREMINING PLAN AND AFFECTED LANDS Exhibit C is intended to fulfill the requirements of Sections 34-32-112 (4), subsections (c), (e), (f), (g), (h) and (i) of the Colorado Mined Land Reclamation Act as outlined in the Mineral Rules and Regulations of the DMG and the Mined Land Reclamation Board. Generally, the required information relates to adjacent property ownership, the name and location of surface features and structures within 200 ft of the boundaries of the affected land, existing topography, the total area of mined and affected lands, vegetation and water resource information as required by the Division. Adjacent property ownership for the Longmont Operation is listed on the accompanying Figure C-1, Exhibit C - Premining Plan. Existing adjacent land use is rangeland to the north and pasture and crop land east of the property, an open lake (reclaimed sand and gravel pit) immediately east of the middle of the property, and Weld County Road 20.5 and pasture land south of the property. Boulder Creek bounds the property along the west and northwest sides. The premining topography of the area is also shown on Figure C-1, and is taken from USGS quadrangle topography transferred onto a recent air photo base map. The ground surface ranges from approximately El. 4865 to El. 4880 and dips gently to the north towards the confluence of Boulder and St. Vrain Creeks, and locally to the west towards Boulder Creek. In addition, 100-year flood elevation contours are depicted on Figure C-1 taken from a Colorado Conservation Board flood map. The total area to be involved in the operation, including mined areas and areas of ancillary operations, comprise approximately 202 acres of the entire approximately 213 acres owned by Cooley. Current land use is irrigated pasture/cropland and non-irrigated rangeland. Cattle are currently grazing on the property. Information included in Exhibit G - Water Information is also included on Figure C-1. An inset map with a map key identifies all permitted well owners within approximately one mile of the site. The list of well owners that accompanies the water information inset map on Figure C-1 is included in the text of Exhibit G. 5 '!/'la� A wildlife assessment was requested of the State Division of Wildlife. No threatened or endangered species, nor any critical habitats were identified. The assessed impact to wildlife is minor. Additional wildlife information for the site in its premining condition is included in Chapter IX, Exhibit H - Wildlife Information. The type of present vegetation on the permit area is generally characterized by pasture grasses interspersed with widely scattered, isolated clusters and single cottonwood trees along Boulder Creek. Detailed vegetation information is contained in Exhibit I of this permit application. An inset map for the soils information described in Exhibit I - Soils Information has been included as part of Figure C-I. The soils inset map is from the Soil Conservation Service Soil Survey report for the site area. The accompanying text is included in Exhibit I. As part of this permit application, Cooley has performed a wetlands delineation and a preliminary Spiranthes orchid habitat assessment of the property to evaluate potential sensitive wetland and endangered plant areas that could be affected by the proposed mining operation. The wetlands delineation, which was presented to and approved by the U.S. Army Corps of Engineers, identified 3.6 acres of jurisdictional wetlands and 9.4 acres of non jurisdictional wetlands. The jurisdictional wetlands occur entirely along Boulder Creek within an area that is to be established as a buffer zone for riparian wildlife habitat and which will not be affected by mining. Finally, an initial assessment of viable habitat for the Spiranthes orchid has identified only the jurisdictional wetlands area (that would be protected) as viable habitat for Spiranthes. This assessment and the proposed design of the operation which precludes infringement on the habitat means that no Spiranthes survey will be required for the site. �r A 6 /'11'1 V. EXHIBIT D - MINING PLAN The proposed Cooley Gravel Company Longmont Operation comprises approximately 213 acres of rangeland lying east of Boulder Creek and north of County Road 20.5 in southwestern Weld County. The entire site lies within the Boulder Creek floodplain. Surface mining of alluvial sand and gravel is proposed for the entire site within normal setbacks with a wetlands/wildlife buffer zone to be established along Boulder Creek. Following mining, the site will be reclaimed as an open lake or as a sealed water storage reservoir with both reclamation plans having a revegetated, irregular shoreline for wildlife habitat. The purpose of this exhibit is to describe in detail the proposed mining plan for the operation. The accompanying Figure D-1, Exhibit D - Mining Plan, portrays the elements of the proposed mining operation as described in this narrative. Concurrent with the submittal of this Regular (112) Permit application to DMG, Cooley has also submitted an application for a Special Use Permit for sand and gravel mining and reclamation to the Weld County Board of County Commissioners. The content of that application is essentially identical to this State permit application. The differences include a County format permit application form and the addition of a Road Maintenance Agreement. Cooley is proposing to mine the property in four phases as shown on Figure D-1. Phase One will consist of development of the gravel plant and asphalt and concrete batch plants on approximately 20 acres at the southeast corner of the site and mining of approximately 54 acres surrounding the plant areas. Phase Two will extend mining to the buffer zone along Boulder Creek to the west and northwest, and north to the boundary between Section 16 and Section 9. Phase Two will encompass approximately 89 acres. Phase Three comprises the approximately 38 minable acres of the quarter- quarter section of Section 9 within the Cooley property. Phase Four will consist of moving the gravel, concrete and asphalt batch plants and mining the remaining 21.5 acres below the former plant sites. All of the plants may or may not be utilized when mining the Phase Four area. Processing operations will be relocated just west of the Phase Four area during mining of Phase Four, if the plants remain on site. Only pit-run materials may be removed from the site, minimal processing done on the aggregate, or continued full operations may occur during Phase Four. During mining of the four phases, only approximately 25 acres will be undergoing mining at any given time. 7 rl�� Based on our current assessment of the property's reserves and overburden thickness, volume calculations for the minable acreage as shown on Figure D-1, a waste factor of five percent, and a probable maximum production rate of 500,000 tons per year, the following timetable is proposed for the four mining phases: Mining Phase Minable Acreage Production (Million Tons) Approximate Duration (Years) Phase One 53.7 1.79 3.6 Phase Two 89.0 2.98 5.9 Phase Three 37.8 1.26 2.5 Phase Four 21.5 0.7 1.4 TOTALS 202.0 6.73 13.4 It is assumed that all mining operations, including initial mobilization, plant relocation for Phase Four mining, and final reclamation of grading and seeding will be accomplished within a 15 to 20 year life span given current economic projections and anticipated production. Based on these projections and the above description, the following table has been prepared summarizing "Areas of Disturbance" during mining. TABLE D-1 AREAS OF DISTURBANCE" (AND DURATION OF PHASES) COOLEY GRAVEL COMPANY "LONGMONT OPERATION" WELD COUNTY, COLORADO TYPE TOTAL (acres1 Phase One (Approx. 4 Years) Major 53.7 Moderate 21.5 Minor 0 8 TYPE TOTAL (acres) Phase Two (Approx. 6 Years) Major 89.0 Moderate 21.5 Minor 53.7 Phase Three (Approx. 3 Years) Major 37.8 Moderate 21.5 Minor 142.7 Phase Four (Approx. 1.5 Years) Major 21.5 Moderate 20.0 Minor 160.5 (" Major, moderate and minor disturbance as per DMG rules and regulations. A total of 202 acres within a 213 acre property will be disturbed. The total area of disturbance by mining phase for reclamation considerations includes both areas of moderate and major disturbance. This is summarized in the following table. TABLE D-2 TOTAL DISTURBED ACREAGES BY PHASE (MODERATE AND MAJOR): Phase One 75.2 Phase Two 110.5 Phase Three 59.3 Phase Four 41.5 9 The proposed mining operation will consist of conventional wet or dry mining (without a slurry wall) of surficial sand and gravel. Mining will include the following elements, some of which (e.g., plant area setup and dewatering trench excavation for Phase One) will occur concurrently: • Fencing improvements • Topsoil stripping and stockpiling • Plant area and roadway layout and construction • Perimeter dewatering trench excavation • Excavation/transfer of pit-run material to field hoppers • Conveying and processing • Concrete and asphalt batching • Product hauling • Reclamation grading and planting • Slurry wall construction (optional) Initial work will consist of improvements (if necessary) to perimeter 4-strand barbed wire fencing, erection of six foot chain link fencing around some or all of the plant areas, topsoil stripping and stockpiling, plant construction, and Phase One area dewatering trench excavation. Topsoil berms will be concentrated along County Road 20.5 and along the southern end of the eastern site boundary to minimize the visual impacts of the operation. Dewatering trench excavation will be performed with an excavator down to the top of or up to several feet into the underlying clay shale bedrock. Trench sidewalls in bedrock will be excavated approximately vertical. The trenches will be constructed to develop flow to discharge locations and minimize evaporative losses. Ground water will drain from the alluvial sand and gravel, collect in the trenches and be discharged to Boulder Creek under an NPDES discharge permit as shown on Figure D-1. Dewatering trench flow will provide the source water for processing. Additional information related to dry mining via dewatering trenches is included in Exhibit G - Water Information (Chapter VIII). Mining excavation will be performed by loaders and/or scrapers at temporary excavation slopes of 1:1 (H:V). As mining progresses from the southeast towards the west and north, field conveyors, 10 f{�A hoppers and transfer points will be utilized to provide in-pit loading locations and conveyance to the gravel plant area. No stockpiling is proposed within the 100-year floodway. Other possible equipment will include a dozer and an excavator, and miscellaneous support vehicles. A wash water pond will be established at the north end of the gravel plant area which will be filled from the dewatering trench. The plant will discharge wash water to an in-pit sedimentation pond which will discharge clear water back to the dewatering trench. Concrete and asphalt batching will be done on site and is anticipated to constitute the primary disposition of the processed sand and gravel (approximately 60 percent). Concrete and asphalt, and to a lesser extent sand and gravel, will be hauled from the site east on County Road 20.5 to Rinn. Trucks will then head north on County Road 7 to State Highway 119 to connect to destination roads. Hauling west on County Road 20.5 will be limited to local deliveries within approximately five miles of the operation to the west and southwest where County Road 20.5 west provides a more direct route. Reclamation grading and seeding will follow the mining operation. The following exhibit, Exhibit E - Reclamation Plan, provides the details of the proposed site reclamation which, in general, will consist of regrading and seeding excavation slopes, constructing an east-west earth dike across the center of the site to create two reservoirs with irregular shorelines if a sealed water storage facility is completed, and planting trees and shrubs along Boulder Creek to enhance riparian habitat. Slurry wall construction has been considered both as a potentially necessary mining operation element and as an optional reclamation plan element. Detailed engineering of the optional slurry wall is proposed to be done after a permit is obtained or very soon after mining has begun when performance evaluations can be made, or should reclamation as a sealed water storage facility be desired. During mining, no slurry wall should be required to limit ground water inflows to the mining excavation, except possibly along a portion of the west edge of the Groom parcel (#131316000034) where an open lake (reclaimed sand and gravel pit) exists. Construction of a partial or complete slurry wall surrounding the permit area may occur prior to mining in that area, depending upon costs and return. Cooley proposes to install two ground water monitoring wells along the west side of the existing open lake within the 30 ft setback and evaluate the need for, and potential optional design length of, a slurry wall along the eastern property boundary to limit potential impacts to the lake and 11 associated water rights. If conventional wet mining with a dragline or long-reach backhoe is performed, then no lowering of the gravel lake would occur. No slurry wall is planned along Boulder Creek if conventional dry mining is performed because dewatering water will be discharged to the creek. No negative impacts to Boulder Creek are anticipated. A schematic detail showing a typical mining plan section including the optional slurry cutoff wall is included on Figure D-1, Exhibit D - Mining Plan. A slurry wall completely surrounding the site is also being considered as an optional reclamation plan element. Current plans are for reclamation as an open lake in contact with ground water. The water information included in Exhibit G and the augmentation plan being prepared for the State Engineer's office are for the open lake option and associated consumptive use through evaporation. Depending upon the marketability of a sealed water storage reservoir, a slurry wall may be constructed by Cooley as described in Exhibits E and F as an optional alternative reclamation end use. 12 VI. EXHIBIT E - RECLAMATION PLAN The primary focus of reclamation of the site following mining is the creation of a stable, vegetated, irregular shoreline around the proposed open lake depicted in Exhibit F - Reclamation Plan Map (Figure F-1). Reclamation will occur concurrently with mining and is expected to be completed by the year 2012. The final reclamation land use, in this scenario, will be an open lake water resource and wildlife habitat area. An optional, alternative water resource reclamation land use may be developed instead of the open lake scenario presently proposed for permitting. This would consist of the identical reclamation plan for the open lakes, but with the addition of a slurry cutoff wall surrounding the site. This plan would be implemented if the economics associated with a buyer of the resulting sealed water storage reservoir, slurry wall construction costs, and water rights and consumptive use issues were favorable. Reclamation, as for mining, will proceed from the southeast corner of the site from the plant areas towards the west and north. Final reclamation grading will be in the Phase Four mining area where the initial plant areas will be located and will include construction of a dike to create two reservoirs if a sealed water storage facility is built. Grading will be followed by planting of trees, shrubs and grasses on newly established shoreline and side slopes. Grading will be performed to create a natural looking open water lake within the existing floodplain topography. The temporary 1:1 (H:V) excavation side slopes will be reclaimed with overburden and waste soil materials to create stable 3:1 shoreline slopes. The 3:1 shoreline slopes will extend to ten feet below the proposed maximum pool elevation, below which they will be steepened to 2:1 slopes. No excavation "highwalis" will be left at the site. Backfilling will occur as each mining year is completed. Grading will be uniform and continuous and performed in such a manner to provide stable slopes, minimize erosion and limit siltation. The time table for each mining phase, and hence for each reclamation phase, is included above in Exhibit D. No acid or other toxic forming materials are known to exist in the topsoil, overburden or sand and gravel to be excavated at the site. Refuse generated on the affected land will be contained and hauled 13 /'cam to a transfer station or solid waste landfill facility. No refuse will be disposed of on the affected lands. No swimming facilities are planned for the private, open lake end land use. The topsoil and silty overburden soils will be stockpiled along the southern site boundary and along the south end of the eastern boundary within the excavation setbacks. Topsoil and overburden stockpiles that will remain in place for periods longer than one growing season will be seeded with a fast-growing temporary cover seed mix to protect them from erosion by wind or precipitation. Reclaimed slopes and disturbed excavation bank tops will be recovered with six to ten inches of topsoil material prior to planting and seeding. Topsoil spreading will be performed in a manner to minimize the potential for overcompaction and, hence, create a viable root zone. A limited number of cottonwood trees and snags will be incidentally excavated near the western limits of mining. A 50 ft buffer zone will be established along Boulder Creek to protect riparian wildlife habitat, preserve jurisdictional wetlands and preserve additional trees. Replanting of trees to enhance shoreline vegetation and habitat will be performed along Boulder Creek. The Soil Conservation Service (SCS) has been contacted regarding revegetation and fertilization recommendations. Their response (included at the end of this Exhibit) has been utilized where practical and a revegetation plan has been developed as part of this reclamation plan. Revegetation is an important part of this reclamation plan. After backfilling and grading, planting and seeding will be initiated as soon as practicable. This will usually be at the beginning of the following growing season after a given mining year is completed. For lake shoreline and shoreline side slopes to ten feet below maximum pool elevation where grasses will be planted, the following seed mix and application rates will be used: Species Percent of Mix PLS°V/Ib/ac Lbs/ac Switchgrass 25 x 4.5 1.13 Western Wheatgrass 30 x 16.0 4.80 Alkalai Sacaton 45 x 1.5 .70 °J Pure Live Seed ��// 14 These seeding rates assume that a drill will be used for seeding. Seeding will generally be completed during November through April, preferably in the late Fall. In order to ensure successful planting, mulch will be used. Straw mulch at approximately two tons per acre will be used. Overburden soils will be tested for primary nutrients (nitrogen, phosphorous and potassium) prior to selecting an appropriate fertilizer, which will be used at the time of seeding. The mixture for water edges will add Reed Canary grass to the above species mix at the rate of 0.5 to 1.0 lb per 1,000 linear feet of shoreline. The grass seed will be planted with a grass drill equipped with depthbands and press wheels. Seed will be planted approximately one-half inch deep. In shallower areas, marsh and aquatic plants will establish themselves. These plants will probably include species of Cattails, Sago Pondweed, Widgeongrass, Wildmillet, and Bullrushes. Over time, the aquatic plants will spread around the entire shoreline and help buffer against shore erosion from wave action and water level fluctuation. The purpose of the revegetation is to establish a healthy native plant community. A significant invasion of pest weeds would rob desired plants of nutrients and moisture and would be contradictory to the proposed reclamation. Therefore, selective areas will be mowed periodically to control weeds. The weeds will be mowed when they reach a height of 12 inches during the first growing season. Along limited portions of the shoreline of the newly created lakes, clusters of trees and shrubs will be planted to create a more natural appearance of the lakes. Trees and shrubs will be selected from the recommended list below: 15 Tata Green Ash Frexinus pennsylvanica Western Cottonwood Populus sargentii Narrowleaf Cottonwood Populus augustifolia Lanceleaf Cottonwood Populus acuminata Willows Salix sp. Shrubs Snowberry Symphoricarpus albus Buffaloberry Shepherdia argentea Cistena Cherry Prunus padus Bluestem Willow Salix irrorata Golden Current Ribes aureum Dogwood Corpus stolonifera Multiflora Rose Rose multiflora Deciduous trees will be one or two year old saplings from 18 in. to five feet tall and deciduous shrubs will be in one and five gallon containers. Along Boulder Creek, two inch caliper cottonwood trees will be planted on approximately 40 ft centers to improve existing conditions along the riparian shoreline. An estimate of reclamation costs has been included in Chapter XIII, Exhibit L - Reclamation Costs, based on the proposed mining and reclamation plans described in this and the preceding chapter. 16 Aka UNITED STATES Soil 9595 Nelson Road #D DEPARTMENT OF Conservation Longmont, CO. 80501 AGRICULTURE Service Phone: 776-4034 March 28, 1994 Haley S Aldrich, Inc. 1600 Broadway Suite 1125 Denver, Colorado 80202 RE: Cooley Gravel Company File No. 20198-00 Reclamation Plan The soils found on this site consist of Aquolls and Aquents and a small area of Bankard sandy loam along the west side of the parcel. These are typical soils for this area and are found along most of the major drainages in the area. All of these soils are subject to frequent flooding which limits there uses. A high water table can be present in the early spring and recede to a depth of 48 inches as the season progresses . Adjacent irrigation greatly affects the water table. As mining operations near completion, all slopes should be graded to a 4H: 1V. Generally, the flatter the slope, the greater the chances for adequate grass establishment. All top soil removed during preliminary mining operations should be stockpiled and then spread back onto the slopes and worked or mixed into the slopes. All foreign water should be diverted away from the slopes and not allowed to run down the slopes. In order to determine fertilizer needs, it is highly recommended to take a soil sample and have it analyzed by a professional lab. Unless this test shows differently, no less than 40# nitrogen (N) and 40# phosphorous (P2O5) should be applied per acre. Ferilizer should be applied immediately prior to seeding and lightly worked into the soil. The final seedbed should be well settled and firm but yet friable. Grass should be seeded between Nov. 1 and April 30th. No seed should be put into frozen soil. The following mixture should prove adequate for this site: Blackwell Switchgrass 30% 1 . 35#PLS/ac. Salado Alkali Sacaton 10% . 10#PLS/ac. Vaughn Side Oats grama 30% 2 .70#PLS/ac. Rosanna Western Wheat. 20% 3.20#PLS/ac. Reed Canarygrass 10% .40#PLS/ac. TOTAL 7 .75#PLS/ac. On all slopes of 3: 1 or flatter, a good quality grass drill having depth bands, packer wheels and an agitator should be used. All seeding operations should be across slope and seeded at 1/2 to 3/4 inch depth. If the seed is broadcast, the above rates shold orated doubldnd the seed harrowingitooapmaximuminto depthhe of surface 3/4 inch. After seeding, the area should be mulched with a minimum of 4 , 000 lbs. of good, clean dry straw or native hay. The mulch should be uniformly spread and then 'crimped' into the soil . Again, 'crimping' should be across the slope. Mulching will protect the soil from erosion and assure rapid establishment of the grasses . Weeds should be monitored and controlled to assure stand establishment. Weeds rob much needed moisture from the grass plants . These soils are not generally suited to the establishment of trees and shrubs . An on site investigation is needed to determine the feasibility and possible tree and shrub species.

The purpose of the map is to depict the expected physical appearance of and portray the proposed final land use for the affected land. The map shows the proposed final reclamation scenario in plan view for final buildout through Phase Four mining for the Longmont Operation as described in detail in the previous exhibits. The proposed reclamation consists of an open lake with wildlife habitat or an optional end use consisting of a sealed water storage reservoir completely surrounded by a slurry wall. The ultimate end use will depend upon negotiations for sale of a sealed water storage reservoir to a suitable owner(s). In lack thereof, the open lake alternative shown on Figure F-1 will be constructed by Cooley Gravel Company. 17 RX VIII. EXHIBIT G - WATER INFORMATION Introduction The proposed mining operation is located in the alluvial plain of Boulder Creek. The alluvial deposit averages approximately 16 feet in thickness. The mining of sand and gravel will necessitate dewatering the alluvial aquifer in the vicinity of the pit. The potential exists for impacting the ground water levels in the immediate vicinity of the excavation. Water levels in the aquifer are expected to decline. However, the operation is not expected to materially injure ground water rights. It is anticipated that the water wells in the area will be able to withdraw their permitted amounts. Suitable mitigation procedures will be instituted if water rights are materially injured. The water wells, and surface water features in the site vicinity are shown on Figure C-1, Exhibit C - Premining Plan. surface Water System The proposed mining operation is located between Boulder Creek and Idaho Creek, a tributary of Boulder Creek. The property lies in the 100 year floodplain of Boulder Creek. The area historically consisted of farmland irrigated by ditches diverting water from Boulder and Idaho creeks. Presently the farmland is interspersed with other sand and gravel mining operations. Immediately east of the Cooley property is a mined and reclaimed pit containing an open lake. Smaller gravel mines lie immediately south of the property. A relatively large, active pit lies northwest of the site across Boulder Creek. The on-site surface water features consist of four small ponds which historically collected tailwater from irrigation. Irrigation water was delivered by laterals of the Smith and Emmons ditch which are located on the southern boundary of the property. The property is currently leased for pasture and grazing and about half the property is irrigated from this ditch. 18 The drainage from the property will be routed to sediment ponds created by the mining. No adverse impact to the surface water system is expected. Ground Water System The mining operation will be dewatered utilizing trenches surrounding the site. Ground water will be discharged from the trenches at a maximum rate of approximately 1500 gpm. The water will be pumped into Boulder Creek and/or to the wash plant. The depth to the water table varies from three to six feet, requiring drawdown in the alluvial aquifer of 10 to 13 ft. A search of the State Engineer's records was made to locate wells within one mile of the site. A map showing the well locations is included on Figure C-1, Exhibit C - Premining Plan. A tabulation of the wells is included in this exhibit as Table G-1. The wells in the area consist of three types; domestic, livestock and gravel pits. There are domestic wells within one mile of the site. The wells withdraw water from the alluvium or the Laramie-Fox Hills aquifer. The area is underlain by shales and sandstones of the Laramie Formation and Laramie-Fox Hills aquifer. Shallow bedrock at the site consists of clay shale that comprises part of the aquitard overlying the bedrock aquifer and mining operations are not expected to affect the bedrock aquifer. Boulder Creek should serve as a ground water divide. Therefore, no alluvial ground water declines are expected west of the creek. Water level declines are expected to occur in the vicinity of the operation to the south, east and north of the mined area. Although it is difficult to predict, based on previous experience we do not expect water levels to be affected at distances greater than one-quarter mile. And at that distance water level changes will be insignificant. Within one-quarter mile, and east of the creek, there are six alluvial wells, two gravel pits and four domestic wells. One reclaimed gravel pit is located on the eastern boundary of the site. Another pit is located south of the site. Four domestic wells are located east and northeast of the site. 19 Water Requirements Ground water will be consumed by four processes: evaporation, water in the product, washing, and dust control. The consumption of ground water will result in depletion from the Boulder Creek system. Evaporation will occur from exposed ground water on the site. Water will be exposed in the dewatering trenches and two small ponds. We estimate the total water surface area will not exceed 2 acres during the mining. The evaporation from the 2 acres will be approximately 5 acre feet per year. The amount of water retained in the product is estimated at 4% by weight. Based on a maximum production of 500,000 tons per year the amount of water consumed is approximately 14.7 acre feet per year. The washing will require approximately 1400 gallons per minute. Water consumed by washing will be accounted in the product water or evaporation from the sedimentation ponds. Water will be used to control dust on interior haul roads as needed. We anticipate that approximately 80,000 gallons per month will be required, or 1.2 acre feet per year. In summary the total estimated water consumption during the mining is as follows: Type of Use Annual Consumption (acre feet) Evaporation 5.0 Product and wash water 14.7 Dust control ii Total 20.9 20 f��A Two options are proposed for reclamation; a lined reservoir or unlined lake. No water will be consumed by a lined reservoir. Therefore, no augmentation will be required. Water will be required to replace the amount evaporated by a lake. The maximum surface area of the lake is estimated at approximately 180 acres. The annual evaporation from the surface would be approximately 450 acre feet. Project Water Supply Cooley owns senior water rights in the South Platte River and Boulder Creek drainages. These rights will be used to augment the depletions caused by the mining operation. As shown previously, the depletions are estimated at 20.9 acre feet per year. Cooley owns 1.5 shares of the Smith and Emmons Ditch which are used to irrigate some of the area proposed for mining. Based on the State Engineer diversion records, the 1.5 shares have historically diverted an average of 236.5 acre feet per year. The water was used to irrigate 110 acres of crops, including corn and beets, and is currently used for pasture grass. The historic consumptive use by the shares is estimated at approximately 142 acre feet per year. The area irrigated by the Smith and Emmons rights will be eliminated by mining. The consumptive use credits will be used to augment mining depletions. The amount of consumptive use credits is more than adequate for augmentation of depletions. However, since the rights were used only during the irrigation season they cannot be used to augment depletions during winter unless the water is stored for winter release. The amount of depletions occurring in the non-irrigation season is approximately 30% of the annual total, or 6.3 acre feet. There are several options available to augment winter depletions. We anticipate one of two sources will be utilized. The most desirable option would be to store the Smith and Emmons rights in an upstream reservoir and release the water as needed. Another option would be to lease effluent from upstream municipalities. 21 Alta Prior to exposure of ground water, a well permit and substitute supply plan will be obtained from the State Engineer. The plan will provide a detailed account of depletions and replacement sources. A reclaimed gravel pit lake will require augmentation of evaporation depletions. In addition to the Smith and Emmons shares described above, Cooley owns approximately 700 acre feet per year of water rights in the South Platte Basin which could be used for augmentation. NPDES Permit An application for a NPDES permit will be submitted for this project. Once a permit is obtained, a copy of the permit will forwarded to DMG. Management of Runoff Cooley Gravel intends to manage on-site runoff under the auspices of NPDES stormwater permit conditions included in the NPDES discharge permit that will be obtained to perform dewatering during mining. Cooley will implement best management practices (BMPs) to prevent storm waters from coming in contact with undesirable materials (fuels, lubricants, etc.) stored on-site to operate and maintain equipment and vehicles. Surface grading of the temporary plant area operations will be performed to control runoff and prevent degradation of surface and ground water quality. Little or no paving will be on-site, so most precipitation will immediately infiltrate to the water table. At the proposed concrete batch plant area, a contained mixer-truck cleanout pit will be constructed that is lined to prevent discharge of cementatious materials to the subsurface. Cleanout materials collected in the pit will be removed approximately on a monthly basis and the material will be reprocessed through the plant. All fuel storage on-site will be in above ground storage tanks sited above anticipated flood elevations and operated in accordance with all Federal, State and local regulations and requirements within a concrete containment area. No runoff management will be required following reclamation as an open lake. 22 TABLE G-1 Map Permit Owner Use' Aquifer Depth QTR/QTR Sec.

EXHIBIT H - WILDLIFE INFORMATION The land surrounding the Longmont Operation she is largely agricultural, with a sand and gravel mine to the northwest and a former sand and gravel mine to the east. The proposed mine she itself presently consists of partially irrigated pastureland. The site contains relatively little cover or suitable habitats area for wildlife. Wildlife present in the area are deer, beaver, muskrat, coyote, fox, skunk, raccoon, waterfowl, rabbits, shorebirds, pheasant, dove, raptors, numerous small rodents and seasonal songbirds. Species typical of a streambank environment may be seen in the area due to the presence of Boulder Creek. There are no known threatened or endangered species, no critical habitats, and the assessed impact to wildlife is minor.

EXHIBIT I - SOILS INFORMATION The soils information provided to satisfy DMG requirements for Exhibit I includes general U.S. Department of Agriculture (USDA) Soil Conservation information. Site-specific geotechnical boring log data collected by Cooley to evaluate the reserve potential of the property also exists, but it is not included for reasons of corporate confidentiality. The following summary of soils information is supported by data excerpted from the USDA Soil Conservation Service "Soil Survey of Weld County, Colorado, Southern Part", dated September 1980. Figure C-1 includes an insert that shows the property outline superimposed on a map base from Sheet No. 20 of the referenced UDSA Soil Survey. This mapping indicates only three soil map units for the property: "3 - Aquolls and Aquents, gravelly substratum", "4 - Aquolls and Aquepts, flooded", and "10 - Bankard sandy loam, 0 to 3 percent slopes". The first two mapped soil units are deep, poorly drained soils formed in recent alluvium. The latter is a deep, well drained soil formed in stratified recent alluvium along streams and rivers. The distribution of the occurring mapped soil units is shown on an inset map on Figure C-1, Exhibit C - Premining Plan, and detailed descriptions of the units are provided on the following pages. The property has been drilled by Cooley and by others at an average boring density of approximately one boring per every six acres. The site-specific boring information is considered confidential by Cooley, but can be made available to DMG on that basis if necessary. �/ 25 SOIL SURVEY INFORMATION FOR COOLEY GRAVEL COMPANY "LONGMONT OPERATION" 26 f( )1/4 8 SOIL SURVEY filter the 1 chate.

The total number of tees is approximately 20 and they range approximately in height from 25 to 50 ft. As mentioned in Exhibits D and E (Mining and Reclamation Plans), trees within the 50 ft wildlife buffer along Boulder Creek will remain and a widened buffer will be employed at the southwest corner of the site to save one particularly large tree near County Road 20.5. Also, two-inch caliper cottonwood trees will be replanted during reclamation on approximately 40 ft centers along the Boulder Creek corridor to enhance riparian habitat. Presently the site is irrigated pasture land covered by indigenous pasture grasses and annual weeds. As part of the application process, a wetlands delineation was performed by Erik Olgeirson, Ph.D., consulting ecologist. Dr. Olgeirson determined that there are 3.6 acres of jurisdictional wetlands and 9.4 acres of non-jurisdictional wetlands on the property. The jurisdictional wetlands are limited to a strip approximately 10 to 25 ft wide along Boulder Creek. These wetlands were mapped and are staked and will be preserved by the proposed riparian buffer zone (50 ft wide). The non- jurisdictional wetlands are the result of the many irrigation ditches and stock ponds that bisect the site. These will be excavated during mining. Dr. Olgeirson's Field Report is included on the following page. The U.S. Army Corps of Engineers has accepted the wetlands delineation performed at the site as documented in the letter included at the end of this exhibit. Anticipated Spiranthes orchid habitat was also evaluated by Dr. Olgeirson. At present, viable Spiranthes habitat is considered restricted to the jurisdictional wetlands that will be preserved within the buffer zone along Boulder Creek. A Spiranthes survey will not be conducted because the viable habitat in the jurisdictional wetlands will not be disturbed by the proposed mining. 27 K .

It is approximately 213 acres and is presently used for the grazing of livestock. There are 5 stock ponds and numerous small irrigation ditches occurring on the site. Wetlands: Both non jurisdictional and jurisdictional wetlands occur on the site. The jurisdictional wetlands are contained within a strip (10' to 25' wide) along Boulder creek. These wetlands are herbaceous wetlands with willow and cottonwood as secondary components. Species occurring here are reed canarygrass(Phalaroides arundinacea), three square (Scrrpus americana),Nebraska sedge(Carex nebraskensis), water sedge(Carex aquatilis) and spike rush (Eleoacharis macrostachya). Wetland were staked in the field with orange pin flags. The non jurisdictional wetlands are a result of the many irrigation ditches that bisect the site. These are irrigated wetlands confined to areas around the ditches or areas where the ditch has blown out or there is seepage. These wet areas lie, for the most part, on the eastern side of the site. The lake to the east of the site may be contributing water to wetland areas just to the west of the lake. The non jurisdictional wetlands are herbaceous wetlands and are more diverse than the wetlands that occur along the river. Sedges, three square, spike rush, bulrush(Scirpus acutus) and reed canarygrass occur within the bounds of these wetlands. These wetlands were not staked: their boundaries were drawn on an aerial photo. ot Q/"T.0,.

Your project has been reviewed in accordance with Section 404 of the Clean Water Act under which the U.S. Army Corps of Engineers regulates the excavation and discharge of dredged and fill material into waters of the United States including wetlands. This letter is to inform you that the wetland delineation March 1994 is considered accurate and acceptable by this office. The wetlands are considered to be waters of the United States pursuant to Section 404 of the Clean Water Act. If a proposed activity requires work within these waters, this office should be contacted for proper Department of the Army permits. This wetlands jurisdictional delineation is valid for a period of three years from the date of this letter unless new information warrants revision of the delineation before the expiration date. Please be advised that the U.S. Fish and Wildlife Service (USFWS) has determined that the Ute ladies' tresses orchid, Spirantheg&ilu aalis, may occur in seasonally moist soils and wet meadows near springs, lakes, or perennial streams and their associated flood plains below 6,500 feet elevation in certain areas in Colorado. This plant species is now officially listed as threatened under the Endangered Species Act. For projects in specific areas, a survey for this plant species, approved by the USFWS, will be required before the Corps of Engineers can issue authorization for work within waters of the United States. I have attached a copy of a November 23, 1992 letter from the USFWS outlining this requirement and a list of recognized $piranthes diluvialis consultants. If you have any questions concerning this matter, please feel free to contact me at (303) 979-4120 and reference action ID #199480264. Sincerely, l , fthr‘Acil\tV\-kfC.

These guidelines were developed by the Service in consultation with biologists and ecologists knowledgeable about the species in order to gain more information about the species, identify potential habitat, and streamline and standardize survey procedures. Soiranthes diluvialis occurs in seasonally moist soils and wet meadows near springs, lakes, or perennial streams and their associated flood plains below 6,500 feet elevation in certain areas in Utah, Colorado, and Nevada. Typical sites include old stream channels and alluvial terraces, subirrigated meadows, and other sites where the soil is-saturated to within 18" of the surface at least temporarily during the spring or summer growing seasons. The moist soil conditions and vegetation composition of known Soiranthes sites suggest that wetlands regulated under the Clean Water Act qualify as potential Soiranthes habitat. Therefore, delineated wetlands, as well as other drier sites matching the description above, should be surveyed if they occur in specified areas in Nevada, Utah, and Colorado. Surveys are required for appropriate sites below 6,500 feet elevation in the following areas in Colorado: a. Boulder and Jefferson Counties; b. The South Platte River 100 year floodplain and perennial tributaries from the Front Range as far east as Brush, Morgan County; c. The Fountain Creek 100 year floodplain and perennial tributaries from the Front Range to the southern boundary of El Paso County; d. The Yampa River 100 year floodplain and its perennial tributaries from Steamboat Springs west to the Utah border. Page 2 Documentation of compliance with survey requirements and recommendations is accomplished through submission to the Service of a survey report. The Service will respond with a letter indicating acceptance of the report. Copies of the interim requirements can by obtained by contacting the Service at one of the following locations: Bernardo Garza U.5. Fish and Wildlife Service 730 Simms St., Room 290 Golden, CO 80401 (303) 231-5280 Lucy Jordan U.S. Fish and Wildlife Service 529 25 1/2 Road, Suite 8-113 Grand Junction, CO 81505 (303) 243-2778 The Service recommends that this letter of notification be copied and distributed to anyone planning a project in areas that meet the description of potential Soiranthes habitat as described above.

EXHIBIT L - RECLAMATION COSTN As described in Exhibit E - Reclamation Plan, and as shown on Figure F-1, Exhibit F -Reclamation Plan Map, the proposed reclamation will consist of open water (either open lake or sealed water storage reservoir) with reclaimed shoreline seeded with native grasses. Along Boulder Creek, trees and shrubs will also be planted with two inch caliper cottonwood trees planted on 40-foot centers. Because of the open water reclamation, most of the site will not be regraded for seeding, but will be submerged. The following assumptions were made to develop the reclamation cost table presented below: • The total site area is 213 acres, 202 of which will be disturbed and eight of which constitute undisturbed mining area perimeter (setbacks and Boulder Creek buffer zone). • Overburden backfill will be at 3:1 (WV) to ten feet below maximum pool elevation; topsoil will be placed and slopes reseeded, fertilized and mulched above pool elevation. Ten feet below maximum pool elevation, reclaimed slopes will be at 2:1 (WV) with no topsoil or reseeding. The 2:1 (H:V) slopes are assumed to extend only four feet above the lake bottom based on anticipated pool elevations. • No reseeding will be performed on lake bottom areas. • The embankment separating the proposed North and South Lakes will be constructed from on- site earth materials should a sealed water storage reservoir be constructed. If insufficient overburden (silty) materials are available, then the embankment will be constructed of sand and gravel from Phase Four mining with a clay shale core excavated from shallow on-site bedrock. • 29 TABLE L-1 ESTIMATED RECLAMATION COSTS Approximate cost va Activity Amount Total Cost 1.

OTHER RELEVANT SITE INFORMATION 20.01 CULTURAL RESOURCES During preparation of this permit application, the Colorado Historical Society was contacted and given site location and proposed operations information. The Historical Society searched the Colorado Cultural Resource Inventory and found no known sites within the project boundary. The Society recommended undertaking a cultural resource survey if the proposed affected lands have not already been extensively altered because of the site's proximity to Boulder Creek. The Historical Society's letter is included at the end of this Chapter. Approximately 85 percent of the property and proposed permitted area has been grazed and under cultivation for more than 60 years. The remaining land on the site occurs along the Boulder Creek corridor and here again, cattle grazing has also occurred. Because of these recent historic activities that have altered the proposed affected land, and because we are proposing a 50 ft setback along Boulder Creek where the possible activities of ancient peoples would likely have been concentrated, Cooley Gravel Company feels a Cultural Resource Survey is not necessary for the site. 20.02 FIRE PROTECTION The Mountain View Fire Protection District was notified about the proposed mining and processing operations at the Cooley Longmont Operation. The District has informed Cooley that the proposed operation is within the boundaries of the Fire District and will receive services. A copy of the letter from the District is included at the end of the this Chapter and Cooley intends to comply with the code, permit and fee requirements described therein. ■P07729.19'1 38 K�� art COLORADO HISTORICAL SOCIETY The Colorado History Museum 1300 Broadway Denver,Colorado 80203-2137 February 25, 1994 Alan L.

A search of the Colorado Cultural Resource Inventory has indicated that there are no known sites located within the boundaries of this project. However, the location of this proposed pit makes it highly probable that prehistoric and historic sites may be present. If there have been no extensive land altering activities in the project area, we recommend that a cultural resource survey be undertaken to determine if eligible cultural resources will be impacted by project activities. This is done in accordance with the Colorado Register of Historic Places Act (24-80.1) . if we may be of further assistance please contact Jim Green at 866-4674. Sincerely, elf James E.

Howard, Senior Geologist Haley and Aldrich Inc. 1600 Broadway, Suite 1125 Denver, CO 80202 RE: Cooley Gravel Company Proposed "Longmont Operation" Sand and Gravel Mine Dear Mr. Howard: I am responding to your letter, dated March 17, asking about the proposed Cooley Gravel Company facility north of WCR 20.5. The proposed mine is within the boundaries of the Fire District and receives service from the District. The Fire District has adopted the 1991 Edition of the Uniform Fire Code and the activities in the mine will be covered by this Code. The principle applications of the Code to a ravel mine will be for tank installations for flammable or combustible liquid, fueling operations, vehicle repair, including welding, and any use of hazardous materials. Tanks for flammable or combustible liquid storage or dispensing, either temporary or permanent, need to be installed in accordance with the requirements of the Code. The installation and use does require a permit from the Fire District. The Board of Directors of the Fire District has adopted a plans review/development fee. I have included a copy of the resolution of the Board of Directors adopting the fee. This fee will apply to all actions taken by the District in regard to the Cooley project, including the review of the referral sent by the Weld County Planning Department. Since the Cooley project is one of the type included in the Director's resolution, a deposit of $200.00 will need to be sent to the Fire District. A separate account will then be established in the name of the Cooley project.

The property is owned by Cooley Gravel Company, 3609 South Wadsworth Boulevard, Suite 300, Lakewood, Colorado, 80235. The site is located approximately two miles southwest of the Del Camino development, the intersection of I-25 and Colorado Highway 119, and as the vicinity map indicates, lies adjacent to Boulder Creek. Properties along Boulder Creek in this vicinity have a high commercial value for sand and gravel as seen by the number of gravel mines in the immediate area. The property is presently zoned agricultural which allows sand and gravel extraction under the provisions of a Use by Special Review Permit. This site has been deemed to contain commercial mineral deposits. As stated in the Weld County Comprehensive Plan, the present economy in the front range corridor is causing an increasing demand for sand and gravel extraction in Weld County. Also, no building development is allowed on sites underlain with commercial mineral deposits until extraction of the mineral resources is complete. The proposed mining and reclamation plans are detailed in the enclosed application. The area was investigated for its potential use as farmland. Due to the relatively thin layer of overburden, much of the water used in irrigation permeates to the gravel situated below and recharges the alluvial aquifer. Table 5 of the USSCS "Soil Survey, Weld County, Southern Part" reveals that crops are seldom grown on this site because the soils are unsuitable for crop production. The applicant proposes safeguards to prevent access to the site during nonworking hours with secure fencing and locked gates. All site operations will occur within the Page 2 requirements of applicable permits thus providing protection for the safety, health, and welfare of the inhabitants of the neighborhood and the county. As previously stated, the proposed use is compatible with the surrounding land uses which consist of sand and gravel mining, some farming, and oil and gas production. As the demand for more gravel for construction purposes increases, more of the land along Boulder and St. Vrain Creeks will become gravel mines. Noise levels are not expected to exceed those normally associated with the surrounding agricultural land use or the adjacent mining and oil and gas producing facilities. Included as part of the application is a proposed road agreement which provides for road maintenance in accordance with Weld County requirements. The site lies in a floodplain, but is not in a geologic hazard zone or airport overlay district area. The application includes provisions to accommodate the effects of the floodplain. We hope that this application has addressed the Use by Special Review requirements and the concerns of Weld County. If you have any questions, please contact us.

The County roads considered in this agreement are haul routes that were established by land use permits previously granted by the County and are as follows: Weld County road 7 between Colorado State Highway 119 and Colorado State Highway 52;Weld County Road 20.5 between Weld County Road 7 and the entrance to Cooley's gravel mine, which is a distance of approximately 3000 feet; Weld County road 18 between Weld County Roads 7 and 5; and Weld County Road 5 between Weld County Road 18 to County Road 7. 2. Cooley is restricted to hauling on the County roads identified in Paragraph I above. 3. The County will, to the best of its ability within the restrictions of the law, require future gravel operators that use the haul routes described in Paragraph I above, to participate in Road Maintenance and Improvements Agreements as outlined herein. 4. Cooley or future gravel operators are required to share in reasonable future maintenance and improvements when such maintenance is related to their hauling impacts. 5.
