Hall-Irwin will mine approximately 89 acres of the total 134.21-acre property. Upon completion of the mining and reclamation, the site will be used for water storage. Please see the attached map for the specific location of the area to be mined. Existing Conditions This site is irrigated agricultural land, presently used to produce corn and oats. Topography of the area to be mined is generally flat, sloping slightly to the east. There is a significant commercial deposit of sand and gravel located in the alluvium of the South Platte River on this property. The South Platte River lies just to the north and west of the site. Portions of the site may flood during periods of high runoff as portions of the area to be mined are in the 100-year floodplain (see Mining Plan Map for location of floodplain). Development of the mining and reclamation plan incorporated measures to mitigate the impact of the operation on floodwater. Hall-Irwin has completed a Floodplain Development Permit for this operation. In addition, the Plumb Ditch borders the site to the south. Surrounding land uses include residential and agricultural. There are no existing buildings on the parcel, however there are several oil and gas wells, tanks and appurtenances that will not be impacted by the mining operation. A stability analysis was conducted and used in the development of the mining plan. Hall-Irwin is in the process of obtaining development agreements with the oil and gas companies.

Hall-Irwin Corporation Page 11 of 35 MLRB 112 Permit Application EXHIBIT D MINING PLAN The information for this section is intended to satisfy the requirements outlined in Section 6.4.4 of the Colorado Mined Land Reclamation Board's Construction Material Rules and Regulations. A. Background The purpose of this application is to obtain authorization for Hall-Irwin Corporation (Hall-Irwin) to mine, process and sell sand and gravel, sell landscape materials, and operate concrete, recycling and asphalt batch plants at the Water Resources, LLC property. Hall-Irwin will mine approximately 89 acres of a +134.21-acre parcel located near Greeley, Colorado. Please see the attached Mining Plan Map for the specific location of the area to be mined. B. Operational Methods a. Description of mining method: The applicant will begin mining at the northeast side of the property and proceed west through the site in phases to minimize the amount of land disturbed at any one time. The site will basically be mined beginning on the northern most half of the site mining phases 1 and 2 from west to east. Phases 3-6 are in the southern and western portions of the site and will be mined east to west, starting at the point furthest from the processing area and working toward it. Please refer to the Mining Plan Map for details on the phasing order. Site preparation Initial disturbance of the property will include: • The slurry wall will be constructed around the perimeter of the mining area. • The perimeter berms will be installed along Weld County Road (WCR) 58. The applicant will plant grass along the berm to help screen the site and install a split wood rail fence for visual interest. The berms are designed to allow historic drainage and flood waters to pass through the site unobstructed. • The area adjacent to the entrance will include signage for the facility. Once mining is complete, the signage will be removed and the entrance will serve as access to the water storage reservoirs. • The overburden material from Phase I will be used to fill the necessary structures in the processing area above the 100-year floodplain. Proposed Mining Process for Each Section Before any mining commences, the operator will install a dewatering trench around the mining area. This water will be pumped into the existing irrigation/drainage ditch located along the northern edge of the property. The applicant will obtain a discharge permit from the Colorado Department of Hall-Irwin Corporation Page 14 of 35 MLRB 112 Permit Application Public Health and Environment (CDPHE). If any discharge agreements are necessary, they will be obtained prior to release of any discharge from the site. The applicant will comply with all CDPHE regulations including monitoring and reporting requirements for the life of the mine. After the Phase 1 area is dewatered, scrapers will strip the topsoil and create the berms or stockpile it. Next they will strip the overburden and use it to raise structures proposed in the processing area above the 100-year floodplain elevation. Any remaining overburden will be stockpiled and ultimately be used in reclaiming and sloping the shore or sold. When the alluvium is sufficiently dry, an excavator will place the gravel in haul trucks or on conveyors to transport the material to the processing area. As the area is mined, overburden will be placed along the edges to create the shoreline of the future reservoir. Topsoil will be placed on finished slopes above the high waterline and the area will be seeded. After the mining has been completed, the dewatering trench will be extended to include the next section to be mined and the process will begin again. Imported Material Hall-Irwin may import materials for processing, batch or blending plants and for sale at the landscape yard. b. Earthmoving: sand and gravel will be excavated and loaded into haul trucks, or onto conveyors which will transport the material to the processing area. c. All water diversions and impoundments: the perimeter of the pond will be dewatered by digging a trench approximately 37-46 feet deep to claystone/siltstone material. For the initial phase the water will be pumped into a settling pond before discharge to the South Platte River. Upon completion of Phase 1, Phases 2-6 will likely use Pond 1 as a settling pond prior to discharge. Wash water for the processing equipment will be recycled through a settling pond(s). Refer to the Mining Plan Map for locations of the ponds. Water required to operate the facility has been detailed in the Temporary Substitute Supply Plan (TSSP) submitted to the State Engineer's Office. A copy of the TSSP application has been included in Exhibit G. d. Size of the area to be worked at any one time: excluding the processing area and perimeter screening berms, a maximum of 21.3 acres will be disturbed at any one time. The site will be dewatered in phases as mining proceeds. Initially, the dewatering trench will be located around the perimeter of the area to be mined. The bottom of the pond will be exposed until mining in the area is complete. Reclamation will be completed concurrently as mining progresses. Once reclamation is complete the pond could be filled for water storage. Mining of the remainder of the property will be completed in this same manner so that reclamation of the entire site is nearly completed as the final material is removed from the site. Reclamation of the site will include grading, Hall-Irwin Corporation Page 15 of 35 MLRB 112 Permit Application replacement of topsoil and seeding and installation of plantings on the pond embankments. Undisturbed areas will be managed for weed control until mining commences on each phase. e. Timing: The applicant anticipates that mining will commence at the end of 2003 or beginning of 2004. The estimated size of the gravel deposit on this site is 6.3 —6.5 million tons. Hall-Irwin estimates it will take approximately 18-20 years to mine and reclaim this property. Annual production is estimated to be between 300,000 and 500,000 tons. This may vary depending on the demand for construction material and may impact the total life of the mining operation. f. Nature, depth and thickness of the deposit to be mined and the thickness and type of overburden to be removed: Terracon performed a geotechnical engineering exploration of this site and prepared a report on January 31, 2000. Please refer to Exhibit I — Soils Information, of this Application for a copy of the Geotechnical Engineering Report. The nature, depth and thickness of the deposit to be mined and the thickness and type of overburden to be removed is described in detail on pages 3 and 4 of that report. The primary commodity to be mined/extracted is sand and gravel. The intended use is for this aggregate is construction materials. Secondary commodities to be mined include screening and sale of topsoil not needed for reclamation of the site. Anticipated incidental production may include gold that is recovered as part of the standard washing and screening operation. Hall-Irwin Corporation Page 16 of 35 MLRI3 112 Permit Application EXHIBIT E RECLAMATION PLAN The information for this section is intended to satisfy the requirements outlined in Section 6.4.5 of the Colorado Mined Land Reclamation Board's Construction Material Rules and Regulations. A. Describe the type(s) of reclamation the Operator/Applicant proposes to achieve why each type was chosen, the amount of acreage accorded to each, and a general discussion of reclamation methods as related to the mechanics of earthmoving. Type of Reclamation Hall-Irwin developed the reclamation plan in conjunction with the landowner, based on the depth and configuration of the gravel resource and the landowners' plans for the property. Refer to the Reclamation Plan Map for the location of the three water storage reservoirs. Earthmoving The topsoil will be replaced by a scraper and generally graded with a blade. All grading shall be done in a manner that controls erosion and siltation of the affected lands, to protect areas outside the affected land from slides and other damage. In addition, all backfilling and grading shall be completed as soon as feasible after the mining process. All disturbed areas shall be regraded and smoothed to a finished grade that is suitable for revegetation or the final land use. As noted previously, the area will be reclaimed as mining proceeds. Finish grading, topsoil placement and seeding will occur throughout the life of the mine. Once the resource is completely removed, dewatering will stop and the finished lakes will be filled with water. Shoreline treatment will include slope variation to encourage diversity in the type of vegetation that will thrive on the reclaimed property. In addition to seeding, trees and shrubs will be planted to create wildlife habitat and visual interest along the shorelines. Typical cross-sections of the shorelines are included on the Reclamation Plan Map. B. Compare the proposed post-mining land use to other land uses in the vicinity and to adopted state and local land use plans and programs. In those instances where the post-mining land use is for industrial, residential or commercial purposes, submit appropriate evidence supporting that they are reasonably assured. The water storage reservoirs will be compatible with the agricultural and residential land uses in the vicinity. Describe how the Reclamation Plan will be implemented to meet each applicable requirement of Section 3.1. Hall-Irwin Corporation Page 17 of 35 MLRB 112 Permit Application The Operator will carry reclamation to completion with reasonable diligence, and each phase of reclamation shall be completed within five years from the date the Operator informs the Board or Office that such phase has commenced. Hall-Irwin will comply with the reclamation measures set forth in Section 3.1.5: • Grading will create a final topography that is appropriate the water storage reservoirs. • Grading will be performed to help control erosion and siltation of the affected lands. • Backliitling 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. Side-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. • Hall-Irwin 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 Applicant will stabilize and protect all surface areas of the affected land, including spoil piles so as to effectively control erosion. • Hall-Irwin will comply with all standards and conditions applicable to classified and unclassified groundwater. Hall-Irwin will protect the existing and "reasonably potential" future uses of groundwater. Hall-Irwin has applied for a well permit and required Temporary Substitute Supply Plan to augment evaporative losses from the ponds. • All aspects of 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-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. • Hall-Irwin will post appropriate signage at the entrance to the mine site. Hall-Irwin Corporation Page 18 of 35 MLRB 112 Permit Application 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 specific location of stockpiles. For reclamation, topsoil will be replaced by a scraper and generally graded with a blade. All 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, all 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 ponds will replace material at a maximum 3:1 slope to meet the grade at the top of the banks. Topsoil will be replaced on the slopes above the high water line. 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 to 6 inches above the surrounding finished grade, consistent with the depth of topsoil at the site prior to mining. 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, Hall-Irwin 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, legumes, 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 has 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 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 schedule indicating how and when reclamation will be implemented. The schedule shall include: 1. An estimate of the periods of time which will be required for the various phases of reclamation; Hall-Irwin Corporation Page 19 of 35 MLRB 112 Permit Application Reclamation Schedule Phase Time Frame Mining/Reclamation Phase 1 1 year Phase 2 2 years Phase 3 3.5 years Phase 4 3.5 years Phase 5 2.5 years Phase 6 2.5 years Upon final mining of the last Phase, Hall-Irwin estimates approximately 3-5 years to reclaim the entire site and establish vegetation. 2. A description of the size and location of each area to be reclaimed during each phase; and Refer to the Reclamation Plan Map in Exhibit F for the size and location of each phase. 3. An outline of the sequence in which each stage or phase of reclamation will be carried out. The sequence of reclamation will include regrading of mined sites, replacement of 6" of topsoil and seeding during the appropriate season to assure adequate moisture for germination and weed control and to assure that grasses can establish. Additional plantings will be installed during final reclamation. Hall-Irwin Corporation Page 20 of 35 MLRB 112 Permit Application EXHIBIT F RECLAMATION PLAN MAP The information for this section is intended to satisfy the requirements outlined in Section 6.4.6 of the Colorado Mined Land Reclamation Board's Construction Material Rules and Regulations. Hall-Irwin Corporation Page 21 of 35 MLRB 112 Permit Application EXHIBIT G WATER INFORMATION The information for this section is intended to satisfy the requirements outlined in Section 6.4.7 of the Colorado Mined Land Reclamation Board's Construction Material Rules and Regulations. 1. The operation is expected to directly affect surface water or groundwater systems: 2. a. Locate on the Map in Exhibit C any water features on the affected land and adjacent lands where structure may be affected by the mining operation. Please refer to the Maps in Exhibit C. b. Identify all known aquifers on the property. Based on our review of the well permit records for wells within 600 feet of the operation, the wells in the immediate vicinity are relatively shallow and assumed to obtain water from the alluvial aquifer associated with the South Platte River. Attached is a list of adjacent wells and well owners with 600' of the site. c. Discuss how water from dewatering operations or runoff will be managed to protect against pollution of either surface or groundwater, both during and after the operation. Water from dewatering operations will be pumped into a small settling pond prior to being discharged into the ditch on the north side of the property. If any agreements are required, Hall-Irwin will not discharge into the ditch until such agreements are executed. Runoff from disturbed areas, piled material and operating surfaces will be diverted onto the mine and discharged via the dewatering system. Undisturbed areas will be maintained as pasture or another suitable cover crop to control weeds and prevent erosion. All areas disturbed by the mining operation will be revegetated per the reclamation plan. 3. Estimate project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. The Applicant has submitted a Temporary Substitute Water Supply Plan (TSSP) to the State Engineer's Office. The attached TSSP addresses the project water requirements, estimated volumes, deletions and a detailed description of how replacements will be made. Approval by the State Engineer's Office assures that existing water rights and associated technical details are addressed. Hall-Irwin Corporation Page 22 of 35 MLRB 112 Permit Application 4. Indicate the projected amount from each of the sources of water to supply the project water requirements for the mining operation and reclamation. Please refer to the attached Temporary Substitute Supply Plan, which has been submitted to the State Engineer's Office. The TSSP addresses the source and amount of water from each water right associated with the property and how each of those water rights will be utilized in the mining operation. 5. Affirm that the Applicant has acquired or applied for a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division at the Colorado Department of Health and Environmental Services. The applicant will apply for a NPDES Permit from the Water Quality Control Division at the Colorado Department of Public Health and Environment. Hall-Irwin will forward a copy of the permit upon request. Hall-Irwin Corporation Page 23 of 35 MLRB 112 Permit Application I EXHIBIT G ATTACHMENT WELLS WITHIN 600' OF THE SITE hi T.

All of this use is considered 100 percent consumptive. Table 1 presents the water consumption for the aggregate mining site. Table 1 presents a summary of the amount of free water surface evaporation from the 0.2 acres of dewatering trenches and a 4 acre silt pond, the water retained in the aggregate product, the concrete batch plant and the dust suppression The total estimated water consumption for the Nissen mine is 45.30 acre-feet annually. Enclosed is a map showing NOAA pan evaporation The total 45.30 acre-feet of annual consumption will result in a depletion to the South Platte River. Monthly river depletions were estimated using the Jenkins Stream Depletion Factor (SDF) method with an assumed SDF value of 8 days. Table 1 shows the estimated 2004 and 2005 lagged mining depletions assuming that the mining commences in 2004_ Even though the pit will be mined prior to the commencement of mining operations, it will be necessary to provide augmentation coverage for the uses associated with the alluvial well 1551F and the limited surface water trapped inside of the slurry wall in accordance with SEO policy. Augmentation Water Supply The water supply for the Nissen aggregate mine is 0.6 shares of Lower Latham Ditch and 2.25 shares of Lower Latham Reservoir. The Lower Latham Ditch has four water rights as shown in the table below. The Lower Latham Reservoir has the priorities as shown below.

Enclosed is a check for $1403.00, which includes $1343.00 TSSP fee and a$60.00 well permit application. Description of Mining Operations. Mining operations at the Nissen mine will produce 500,000 tons of product annually. A future proposed concrete batch plant will produce 100,000 cubic yards of concrete annually. Figure 1, enclosed, shows the location of the Nissen aggregate mine. This mine will be lined with a bentonite slurry wall in late 2003 or early 2004. Mining will not commence until the slurry wall is constructed. Consumptive Use The consumptive use attributed to the Nissen aggregate mine is evaporation from limited open water surfaces from de-watering trenches as the aggregate will be dry mined. In addition to the aggregate production, water will be required for a concrete batch plant batching concrete, gravel washing and on-site dust suppression. The water used in the batch plant, and dust suppression Water Rights • Hydrology • Hydraulics • Water Quality li"I/ear llalrCiravcl I'its'South Platte-Rein Nissen Pit N51'Ragoct Letter doe water,wells #1551F and #13255 were used as a supplemental supply to the 120 acres. The Lower Latham water rights were historically delivered to the 120 acres via the Smith Lateral as shown on Figure 2. Table 3 presents a summary of the historic use for the period 1969— 1996 for the 2.5 shares of Lower Latham Ditch and the 2.25 shares of Lower Latham Reservoir used on the Nissen Farm. The consumptive use attributed to both the 2.5 shares of ditch water and the 2.25 shares of reservoir water was estimated using a maximum field application efficiency of 63 percent and the modified Blaney-Criddle method. Tables 4 and 5 show the river headgate diversions of the Lower Latham Ditch and the calculated reservoir releases of the Lower Latham Reservoir. In addition,Table 3 presents the pro-rata farm headgate deliveries of the 2.5 shares of ditch water and the 2.25 shares of reservoir releases, assuming a 20 percent ditch loss. There are 200 outstanding shares in the Lower Latham Ditch and 156 outstanding shares in the Lower Latham Reservoir. Table 3 also shows the prorated consumptive use of 2.5 shares ditch water and the 2.25 shares of reservoir water and the lagged returns associated with both sources. It was assumed that 50 percent of the return flow volume returned to the river as sub-surface and the other 50 percent was surface return flow. The one-site groundwater return flows were lagged back to the South Platte River using an 8 day stream depletion factor determined from Hurr's 1965 SDF maps. Conclusions The 45.30 acre-feet of average annual pit depletions will be replaced using 0.60 shares of Lower Latham Ditch and 2.25 shares of Lower Latham Reservoir via direct release to the South Platte River. Figure 2 shows all wells located in the vicinity of the proposed Nissen Pit. There are three wells that will be located within 600 feet of the mining area. However, since the pit will be lined prior to when mining operations commence,the de-watering activities associated with the wells will not cause injury to these three wells. The operation of this TSSP pursuant to the conditions established herein, will result in no injury to senior water rights on the South Platte River.

Please refer to the attached Wildlife Assessment by Savage and Savage, and correspondence with associated regulatory agencies. Hall-Irwin Corporation Page 24 of 35 MLRB 112 Permit Application 6.4.8 Exhibit H - Wildlife Information Wildlife Assessment Site Description Savage and Savage conducted a wildlife assessment for the Hall-Irwin Nissen Farms resource site on November 21, 2002. The Nissen Farms resource site comprises approximately 125 acres contained in the S%2 of Section 12 in T5N, R67W of the 6th prime meridian in Weld County, Colorado. The property is bounded on the north by the South Platte River and a flood control levee, the east and south by property fence lines, and the west by Weld County Road 58. Currently, the property has several ongoing land uses including a homestead,agriculture(row crops), and oil and gas production. Adjacent land uses include oil and gas production, agriculture, dairies, and grazing. The property was accessed from Weld County Roads 58. Weather during our site investigation was warm, dry, and clear with a high temperature in the mid-60's (°F). The topography of the site is dominated by the secondary and tertiary alluvial terraces of the South Platte River. The river and primary alluvial terrace are isolated from the project site by a man-made levee running along the north boundary of the property. The elevation of the study area averages 4600 feet and slopes very gently to the northeast. The soils that dominate the site are formed from alluvium and consist of sandy barns and clays underlain by sand and gravel. The significant hydrologic features of the site are the earthen and concrete constructed irrigation ditches used in the farming operations. There are no significant natural vegetation communities within the project site. The project site was planted to oats and corn this season, according to the property lessee, Mr. Ed Schmidt. A cottonwood riparian woodland is located north of the project site along the primary and secondary alluvial terraces of the South Platte River. Small inclusions of prairie cordgrass(Spartina pectinata), reed canarygrass(Phalaris arundinacea),and wild licorice (Glycyrrhiza lepidota)can be found along the banks of the irrigation ditches. Significant Wildlife Resources Tables 1, 2, and 3 list wildlife species that potentially occur on-site according to the Colorado Distribution Latilong Studies (CDOW, 1981, 1990, 1998). The latilong studies address mammals, birds, reptiles, and amphibians. During the site investigation we encountered few wildlife species within the project site. The majority of the wildlife species were observed north of the project site within the adjacent riparian corridor. A list of the species observed adjacent to the site is included on the wildlife field data sheet in the Appendix. A search of the Colorado Natural Heritage Program Biological and Conservation Datasystem identified six species of concern in the general area of the project site (included in Appendix). None of the species were found on the project site. The species of concern included two bird species, one fish, one mollusk, and two plants. None of the species identified were listed or candidates for listing under the Endangered Species Act. None of the species identified have characteristic habitat within the project site. Therefore, no potential for impact to these species exists. Project Effects to Wildlife According to the proposed mineral extraction plan for the project site, none of the riparian corridor will be disturbed, thereby avoiding and protecting the most valuable wildlife habitat adjacent to the project site. Noise and air emissions during mining may cause a temporary disturbance to wildlife. Species such as raccoons, coyotes, beaver, deer, and raptors will continue to use the riparian corridor during mining operations and the site itself when operations are not active. Bird species will use the periphery of the site and the site itself opportunistically, if prey or food species are present. The proposed project will extract material and leave a cell within the site. Permanent reclamation of the site will entail grading, respreading topsoil, and seeding and planting perennial species that will support wildlife species. The mining and reclamation will create a more diverse habitat than is currently present. Areas of open water will sustain additional species of reptiles and amphibians as well as shorebirds and waterfowL The addition of the water will create fringe environments favorable to predatory mammals and raptors, as well as food and water sources for herbivores. With the planting of additional trees and shrubs, additional strata and vegetation layers will be added to the site, creating improved cover, foraging, roosting, and nesting areas for wildlife.

This report regards the proposed site plan review for the Nissen Farms Resource Site in Weld County,Colorado. Based on the information provided,the Service finds the report acceptable and agrees that a population of Preble's is not likely to be present within the subject area. The Service concludes that the proposed project on this site should not have direct adverse effects to Preble's or Preble's habitat. Thus,this site is disqualified for consideration under provisions of the ESA. If the Service can be of further assistance, please contact Barbara Spagnuolo of my staff at(303) 275-2370.

The project will involve development of the site for aggregate extraction with probable post-mining use as municipal water storage. The Nissen Farms resource site comprises approximately 125 acres contained in the S% of Section 12 in T5N, R67W of the 6th prime meridian in Weld County, Colorado. The property is bounded on the north by the South Platte River and a flood control levee, the east and south by property fence lines, and the west by Weld County Road 58. Currently, the property has several ongoing land uses including a homestead, agriculture (row crops), and oil and gas production. Adjacent land uses include oil and gas production, agriculture, dairies, and grazing. The site is approximately 3.5 miles east of Greeley, Colorado, east and north of Weld County Road 58. The project site is depicted on the attached general location map. Based on the USFWS May 21, 1999 survey requirements for Zapus hudsonius preblei, this site needs to be considered for a survey as it is located within Weld County west of Fort Morgan, Colorado below 7600 feet elevation. Based on a field investigation conducted by Savage and Savage on November 21, 2002 and current U.S. Fish and Wildlife Service interim survey guidelines dated May 21, 1999, we believe the Nissen Farms Resource site is exempt from the necessity to conduct a Preble's meadow jumping mouse trapping survey and has very low potential to harbor individuals or a population of Zapus hudsonius preblei for the following reasons. } .yy� M .';A,;34.+4).---.,..4.,...

The project will involve development of the site for aggregate extraction with a probable post-mining use as municipal water storage. The Nissen Farms resource site comprises approximately 125 acres contained in the S'z of Section 12 in T5N, R67W of the 6th prime meridian in Weld County, Colorado. The property is bounded on the north by the South Platte River and a flood control levee, the east and south by property fence lines, and the west by Weld County Road 58. Currently, the property has several ongoing land uses including a homestead, agriculture (row crops), and oil and gas production. Adjacent land uses include oil and gas production, agriculture, dairies, and grazing. The site is approximately 3.5 miles east of Greeley, Colorado, and immediately east and north of Weld County Road 58. The project site is depicted on the attached general location map. The project site is entirely in agricultural production consisting of corn and oats. An irrigation ditch complex comprises the only surface water drainage feature on the property. Vegetation along the immediate margins of the earthen irrigation ditches is comprised of a dense stand of reed canarygrass (Phalaris arundinacea) with scattered individual wild licorice plants(Glycyrrhiza lepidota ). Based on the USFWS November 23, 1992 survey requirements for Spiranthes diluvialis, this site is eligible as it is located within the 100 year floodplain of the South Platte River west of Brush, Colorado in alluvial sandy and gravelly soils. Within the project site, the only areas potentially requiring a survey are those areas immediately adjacent to the earthen irrigation ditches. The remaining project site areas are highly disturbed for row crop agriculture. r Jan McKee Nissen Farms Spiranthes diluvialis Disqualification Request Page 2 We request a disqualification from survey requirements based on the dense stands of reed canarygrass along the irrigation ditches. Based on our inspection of these areas, we concluded that these are not Spiranthes habitat and have very low potential to be habitat. If you have any questions concerning this orchid disqualification request for the Nissen Farms Resource Site, or require additional information please contact us.

In response,I have searched our Biological and Conservation Datasystem(BCD)for natural heritage elements(occurrences of significant natural communities and rare, threatened or endangered plants and animals)documented from the vicinity of the area specified in your request,specifically within the S '/2 of Section 12 in Township 5 N,Range 67 W in Weld County, Colorado. The enclosed report describes natural heritage resources known from this area and gives location(by Township, Range, and Section),precision information,and the date of last observation of the element at that location. This report includes elements known to occur within the specified project site, as well as elements known from similar landscapes near the site. Please note that"precision"reflects the resolution of original data. For example, an herbarium record from"4 miles east of Colorado Springs"provides much less spatial information than a topographic map showing the exact location of the occurrence. "Precision"codes of Seconds, Minutes,and General are defined in the footer of the enclosed report. The report also outlines the status of known elements. We have included status according to Natural Heritage Program methodology and legal status under state and federal statutes. Natural Heritage ranks are standardized across the Heritage Program network,and are assigned for global and state levels of rarity. They range from"I"for critically imperiled or exticurely rare elements, to"5"for those that are demonstrably secure. You may notice that some occurrences do not have sections listed. Those species have been designated as "sensitive"due to their rarity and threats by human activity. Peregrine falcons, for example,are susceptible to human breeders removing falcon eggs from their nests. For these species,CNHP does not normally provide location information beyond township and range. Please contact us should you require more detailed information for sensitive occurrences. There are no CNHP designated Potential Conservation Areas located within your project area. In order to successfully protect populations or occurrences, it is necessary to delineate conservation areas. These conservation areas focus on capturing the ecological processes that are necessary to support the continued existence of a particular element of natural heritage significance. Conservation areas may include a single occurrence of a rare element or a suite of rare elements or significant features. tat}erni f btORISP The goal of the process is to identify a land area that can provide the habitat and ecological processes upon which a particular element or suite of elements depends for their continued existence. The best available knowledge of each species' life history is used in conjunction with information about topographic,geomorphic, and hydrologic features, vegetative cover,as well as current and potential land uses. The proposed boundary does not automatically exclude all activity. It is hypothesized that some activities will cause degradation to the element or the process on which they depend,while others will not. Consideration of specific activities or land use changes proposed within or adjacent to the preliminary conservation planning boundary should be carefully considered and evaluated for their consequences to the element on which the conservation unit is based. The Colorado Division of Wildlife has legal authority over wildlife in the state. CDOW would therefore be responsible for the evaluation of and final decisions regarding any potential effects a proposed project may have on wildlife. If you would like more specific information regarding these or other vertebrate species in the vicinity of the area of interest,please contact the Colorado Division of Wildlife. The information contained herein represents the results of a search of Colorado Natural Heritage Program's(CNI-IP)Biological and Conservation Data System(BCD),and can be used as notice to anticipate possible impacts or identify areas of interest Care should be taken in interpreting these data. Sensitive elements are currently known from within the proposed project area,and additional,but undocumented,elements may also exist(see enclosed report). Please note that the absence of data for a particular area, species,or habitat does not necessarily mean that these natural heritage resources do not occur on or adjacent to the project site,rather that our files do not currently contain information to document their presence. CNHP information should not replace field studies necessary for more localized planning efforts,especially if impacts to wildlife habitat are possible. Although every attempt is made to provide the most current and precise information possible, please be aware that some of our sources provide a higher level of accuracy than others,and some interpretation may be required. CNHP's data system is constantly updated and revised. Please contact CNHP for an update or assistance with interpretation of this natural heritage information.

Consistent with the DMG Lined Pit Guide dated September 2000, Hall-Irwin will bond 20% of the slurry wall cost estimate and commit to submitting the necessary design specifications as a technical revision prior to the exposure of groundwater in the pit. The estimated cost for reclamation is based on a maximum area of disturbance (Phase 3) of approximately 21.3 acres. For the purpose of this estimate it is assumed that the maximum area of disturbance would be completely mined and only 25% of the pond shaping completed for that area. The processing area and haul roads will be disturbed and require reclamation work. Reclamation for Phases 1 & 2 would be 100% complete.

Box 2150 Greeley,Colorado 80632 Re: Hall-Irwin Corporation, Nissen Farms, Weld County, Colorado, Stability Analysis as Required by the Division of Minerals and Geology for Permanent Structures Within 200 Feet of the Mined Area; Tetra Tech RMC Job No. 80-0636.141.00 Dear Mr. Gregg: This letter has been prepared to address Mine Land Reclamation Board(MLRB)Construction Materials Rule 6, Section 4, Subsection 19, Exhibit S - Permanent Man-Made Structures(6.4.19, Exhibit S) for the proposed Nissen Farms aggregate mine. The proposed mine will occupy 89 acres in the South Half of Section 12, Township 5 North, Range 65 West of the 6th Principal Meridian in Weld County,Colorado. The site is in the alluvial valley of the South Platte River near its confluence with the Cache la Poudre River. The South Platte River meanders around the west and north sides of the proposed mine. Weld County Road 58 is south of the mine. Land use in the area is mostly agricultural and rural residential. Numerous gas wells are also present in the area. The Mining Plan(attached for reference) for the project is to mine the site in a total of six phases ranging from approximately 5.9 to 21.3 acres in size. A slurry wall will be constructed around the mine perimeter. The mine will be reclaimed as three ponds, all within the slurry wall perimeter. Certain interior parts of the mine will not be mined in order to leave access for vehicles and pipelines to site gas wells and tank batteries. For our analyses, we have assumed that the mine highwalls on the perimeter of each pond will be vertical. Actual highwalls will likely be less than, but near vertical. Overburden stockpiles may be placed 10 feet from the perimeter of the mined areas. GEOLOGIC STRATA The mine site is located in the alluvial valley of the South Platte River. Geologic mapping at the site (Smith, et al., 1972)' indicates the mine is on the recent alluvial terrace of the South Platte River. Smith,Schneider,and Petri, 1967,"Groundwater, South Platte River Basin,"USGS Water Supply Paper 1658. 1900 S.Sunset Street Suite I-F.Longmont.CO 80501 Tel 303772.5282 Fax 303.665-6959 wwwttrmccom (lb) TETRATECH RMC Mr. Jeff Gregg March 21, 2003 Page 2 Geologic mapping approximately 3,000 feet west of the site by Colton(1978)2 indicates this terrace corresponds with the Post Piney Creek Alluvium. The mapping indicates the bedrock underlying the alluvium is most likely claystones, sandstones, and possibly coal of the Laramie Formation. Data for this analysis was extracted from eight exploratory borings drilled at the site in January 2000 by Terracon(2000).' For reference we have attached a Test Boring Map showing boring locations with corresponding overburden and sand and gravel thickness. The logs indicate that the general subsurface profile consists of approximately two to five feet of overburden silty sand overlying approximately 34.5 to 44 feet of sand and gravel on top of claystone bedrock. The logs indicate the borings encountered approximately one and one half to seven feet of weathered claystone. However, the bedrock was not sampled and was presumably logged from cuttings. Based on our experience, we expect local sandy clay overburden will also be encountered at the site. The total thickness of the alluvial deposit encountered in the borings ranges from approximately 37 to 46 feet. Groundwater depths in the mine area at the time of drilling ranged from approximately four to 12 feet below the ground surface. From a geotechnical standpoint, the sand and gravel will form most of the mine slope. These soils are generally strong and stable,particularly when dewatered. STRUCTURES WITH 200 FEET OF DISTURBED AREAS Structures in the area and at the site are ditches, Weld County Road 58, and gas wells with associated pipelines and tank batteries. Some of the gas wells, tank batteries, and gas lines are within the mine area perimeter. Mining will not encroach within 75 feet of these structures before Hall-Irwin enters into agreements with the owners of these structures regarding future use and possible relocation. All known, permanent,man-made structures within 200 feet of the mined area are listed below: ► Two gas wells, three tank batteries, and associated pipelines and access roads within the mine perimeter near Phases 1, 2, 3, and 4. All of these structures will be located on berms between the mine phases with minimum setbacks of 75 feet from actual mining. D. Gas pipeline approximately 90 feet to the east of the mine. ► The Plumb irrigation ditch approximately 90 feet to the south of the mine at its closest point. ► A gas well approximately 130 feet southwest of the mine. ► A gas pipeline approximately 80 feet(at its closest point) southwest, west, northwest, and north of the mine. 2 Colton,R.B., 1978,"Geologic Map of the Boulder-Ft.

STABILITY ANALYSES We performed stability analyses in order to evaluate potential for damage to existing permanent structures due to mine highwall slope failures. The scenarios modeled were along the mine perimeter with a slurry wall and on the mine interior berms(near Phases 1, 2, 3, and 4)without a slurry wall. Analyses were performed with the XSTABL computer program. We analyzed the most critical soil profile based on exploratory boring data and the mining plan. For this critical slope, we modeled five feet of sandy clay overlying 41 feet of sand and gravel on top of claystone. As required by the Colorado Division of Minerals and Geology(DMG) a vertical perimeter slope was modeled in the analysis. At the mine perimeter, slurry walls were modeled 55 feet from the top of the perimeter mine slope. In addition, a 20-foot construction buffer was incorporated between the slurry wall and nearby structures to allow sufficient space for slurry wall construction. For the interior berm profiles where no slurry wall is present, we modeled a 55-foot setback between the structure and the perimeter mine slope. Groundwater levels on the profiles were inputted to portray site dewatering when nearby ditches carry water. Both of the above-mentioned profiles were analyzed with and without a simulated stockpile surcharge. The surcharge was modeled 10 feet from the top of the mine highwall over a width of 20 feet with a surcharge pressure of 1,200 psf. No laboratory strength tests were performed on soils at the site. The soil strength parameters used were based on typical values for the anticipated soils and our experience at other sites in the area. Weathered bedrock was analyzed at residual strength as required by the DMG. The inputted parameters were: Material Moist Unit Saturated Unit Effective Cohesion " Effective Friction Weight(pcf) Weight(pcf) (pcf) Angle(degrees) Overburden silty sand/ 114 126 50 26 sandy clay Slurry walls 110 122 0 26 Sand and gravel 130 137 0 35 Bedrock 124 134 100 26 Weathered bedrock 110 122 0 14 r ItTETRA TECH RMC Mr. Jeff Gregg March 21, 2003 Page 4 Stability analyses were run on 400 randomly generated circles generated at the mine excavation and highwall, as well as the nearby permanent structure. The Simplified Bishop Method was used to estimate the factor of safety on the most critical surface. The modeling of the residual strength bedrock is conservative, thus the DMG considers a Factor of Safety of one or greater to be sufficient. Input files and graphic profiles of each analyses are attached. Following are the four scenarios modeled and the resulting factors of safety: ► Scenario 1: This scenario was modeled to simulate conditions along the mine perimeter. The mine highwall was modeled as described above with the slurry wall 55 feet from the top of the mine slope and the Plumb Ditch another 20 feet beyond the slurry wall. The ground surface elevation rose beyond the ditch based on the site topographic survey. The resulting Factor of Safety at the ditch was 1.24. ► Scenario 2: This scenario was identical to Scenario 1 with the exception that the surcharge load simulating a stockpile was added 10 feet from the perimeter of the mine. The resulting load was on the resisting side of the failure circle resulting in a Factor of Safety at the ditch of 1.37. ► Scenario 3: This scenario was modeled to simulate conditions on the interior berms of the mine where gas wells, pipelines, tank batteries,and access roads will be present. In this scenario, no slurry wall was modeled and the failure surfaces were run from structures located 55 feet away from the mine highwall. The resultant Factor of Safety was 1.05. ► Scenario 4: This scenario was identical to Scenario 3 with the exception that a surcharge load was added to the analysis to simulate a stockpile 10 feet from the top of the highwall. Again the resultant load was on the resisting side of the failure circle and the resulting Factor of Safety at the structure was 1.16. The mine plan incorporates minimum setbacks accounted for in our stability analysis. Based on our analysis, mining should not pose a hazard to nearby permanent structures. LIMLATIONS Our review is based on regional geologic mapping, present mining plans, bore hole data, and stability analyses using typical strength parameters for the various strata in the critical section. 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.
