Before we schedule our next meeting, it would be useful if you would provide me with some information about the relationship between the distance from the drilling window and the cost to directionally drill. For example, I assume that a drill location 100 feet outside your 400' X 400' window is going to cost less than a location that is 600 feet away. Anyway, it will be useful to have some idea of the cost to drill outside the proscribed drilling window. Thanks, Mike Michael J.

Crosby Division of Reclamation,Mining,and Safety 1313 Sherman Street,Rm.215 Denver, Colo. 80203 RE: Response to C-DOT'S June 4,2007 Letter Dear Erica: The following respond to comments and concerns expressed by Mr.Joe Tntermill on behalf of the Colorado Department of Transportation(C-DOT)regarding the proposed Holton Lakes sand and gravel mine(DMR&S Permit Number 2007-008). Listed below arc C-DOT s comments and the Applicants responses to those comments. 1. The Vicinity Map in the application package shows a bier zone between the start of excavation and the adjacent CDOT Right-of Ff icy. It shows. fifty feet between the top slope of the excavation and US highway 85 ROW and one-hundred foot huffer between top slope of the excavation and NI 52. We consider these to he the minimum widths of virgin undisturbed ground needed between the excavation and the ROW in this area. No excavation, including the slurry walls should be allowed inside these hoer areas. Applicant's Response: The 100-foot setback from the south Right-of-Way(ROW)of Colorado Highway 52 and mining Stage 1 will be used to create a landscape screening buffer between the highway and the mining operation. There will be no slurry wall constructed for mining Stage 1. However,a 300- foot section of slurry wall will be constructed along the southerly limit of the 100-foot set back as part of the overall slurry wall for mining Stage 5. Between the west ROW of Colorado Highway 85 and mining Stages 2 and 3,the minimum mining setback distance is 50 feet. As with Stage 1,the area opposite Stages 2 and 3 will be landscaped to screen the mining area from Highway 85. There will be no slurry wall constructed for mining Stage 2. The slurry wall along the cast side of Stage 3 will be excavated west of and adjacent to the 50-foot setback limit. Ms. Erica Crosby June 8,2007 Page 2 2. ('DOT shares DRMS concerns listed in Item 18 of the adequacy review letter dated April 27, 2007 about the potential negative impact that could he caused by significant flood event. We request that, as a minimum, the suggested mitigation measures shown in Item 18 he utilized for dry pit slopes that parallel C:'DOT ROW. These measures are mining thy pit slopes no steeper than 1:1, including the dewalering ditch, and protect the reclaimed slopes with rip rap. Applicant's Response: The Applicant is committed to protecting Highways 52 and 85 from impacts associated with the mining and reclamation of Holton Lakes. Dining mining,the Applicant will adhere to the recommendations of Scott-Cox and maintain a minimum mining setback from permanent man-made structures of 100-feet. The Scott-Cox safety setback assumes a vertical pit wall during mining; therefore,the Applicant is opposed to a mandated 1:1 pit wall slope during mining where the 100-foot structure setback is applied. The Scott-Cox engineering analysis supports the Applicant's mining approach in this regard. As previously mentioned,it is likely that the slope of the pit wall will vary within a given mining stage as well as from stage to stage. Because the Applicant intends to employ concurrent mining and reclamation practices,the perimeter of any given mining stage will be reclaimed prior to the completion of the mining of that stage. All reclaimed slopes will be backfilled to a minimum slope of 3:1 with rip-rap selectively used if needed. 3. ('.DOT is also concerned with the potential mounding effect that could he caused by the Slurry Walls and the impact it could have on our ROW and drainage structures. Applicant's Response: Currently,within C-DOT's ROW for Highways 52 and 85,there are drainage ditches designed to discharge surface water from the ROWS to the South Platte River. Additionally_ these drainage ditches will act as a ground water cut-off ditches in the event that ground water rises(or mounds)to the elevation of the bottom of the drainage ditch,The Applicant is prepared to work with C-DOT to mitigate mounding effects caused by the slurry walls by installing additional cut-off trenches if needed. 4. There was no mention of the water elevations in the storage lakes, where and how the storage water would enter the lakes, and how or where it would he discharged from the lakes. These are all items to he considered when evaluating the potential damage to highwcrys • • and other adjacent and downstream property. —, Ms. Erica Crosby June 8,2007 Page 3 Applicant's Response: CDOT's comment goes beyond the Division's purview to how the water storage facilities may be operated, maintained and managed after mining and reclamation is completed,and the Board's reclamation bond is released. It is also beyond the Applicant's control as the Applicant has only secured a right to mine gravel and to reclaim the property,the latter to the specification of the landowner. Similar to the Division then,the future use and management of the Holton Lakes property for water storage is beyond the Applicant's authority to control. That stated, it can be assumed that the water elevation in each of the three scaled pits will approximate the elevation of the surrounding alluvial ground water which ranges from three(3) to five(5)feet below ground surface(see cross section A-A' on map Exhibit"F"Reclamation Plan). 5. We understand that the applicant is preparing a report analyzing the effects of a IOU year flood event and possible ways to mitigate danaag►e to the permitted and adjacent areas. We request the opportunity to review this report once it is submitted Applicant's Response: The Applicant will provide C-DOT a copy of any report it is required to prepare to analyze the effects of a 100-year flood event, and ways to mitigate off-site impacts,if any, specifically attributable to the Holton Lakes project. if you have any questions regarding this letter,please do not hesitate to contact me_ Sincerely.

Weld Re 8 School District Response ii INTRODUCTION Ready Mixed Concrete Company is applying for a Use by Special Review Permit in order to mine sand and gravel from portions of Sections 6 and 7, Township 1 North, Range 66 West of the Sixth P.M. Weld County, Colorado. The proposed Holton Lakes Pit is located in unincorporated Weld County adjacent to Fort Lupton, Colorado. State Highway 52 boarders the site on the north and State Highway 85 boarders the east side of the site. The proposed pit lies within the 100-year floodplain of the South Platte River, which cross the subject property, flowing from south to north. The Holton Lakes Pit will be mined in five stages totaling 203 acres. Prior to mining, soil-bentonite slurry walls will be constructed around the perimeter of mining stages three, four and five, which total 166 acres of the 203 acres to be mined. All five mining stages will be dewatered and then mined dry with backhoes and front-end loaders. Excavated sand and gravel will be conveyed from the active stage of mining to an on site sand and gravel processing plant where the aggregate will be crushed, screened, washed and stockpiled. Finished sand and gravel products will be used to supply an on-site ready mix concrete plant or hauled by truck to customers in the area. Depending upon the economy of the region and demand for sand and gravel, the life of the Holton Lakes Pit is estimated to be approximately 10 years. Wherever feasible, reclamation will be done concurrently. The site will be reclaimed for two principal post-mining land uses, wildlife habitat and developed water storage. It is estimated that 4,000 acre-feet of water storage can be developed from mining stages 3-5. 1.0 USR PERMIT APPLICATION DEPARTMENT OF PLANNING SERVICES 1555 N. 17th Avenue,Greeley,Colorado 80631 Phone (970) 353-6100,Ext. 3540 Fax (970) 304-6498 USE BY SPECIAL REVIEW (MINING OPERATION)APPLICATION FOR PLANNING DEPARTMENT USE DATE RECEIVED: RECEIPT#/AMOUNT # 1$ CASE #ASSIGNED: APPLICATION RECEIVED BY PLANNER ASSIGNED: To be completed by APPLICANT is accordance with procedural gude requirements: 1.

Sand and gravel thickness varies from 20-25 feet, overburden thickness is 3-5 feet. h. The Reclamation Plan map is included with this application. The proposed post mining land uses include developed water storage and wildlife habitat. The reclamation process involves the grading and shaping of banks in areas where water storage is proposed (mining Phases 3-5). Mining Phase 2 will be filled with wash fines from the sand and gravel processing plant and Phase 1 will backfilled top-soiled, and re-vegetated. i. Technical advice was provided by the applicants representatives,the Colorado Division of Reclamation, Mining and Safety and Hart Environmental. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22. Answer: The proposed use is consistent with the Weld County Comprehensive Plan. Chapter 22 of the Weld County Code articulates the County's policies regarding mineral resources development. In particular, CM Goal 5 states that the County's policy "provide for timely reclamation and reuse of mining sites in accordance with this Chapter and Chapters 23 and 24 of this Code." The goal of the Holton Lakes reclamation plan is to develop a number of post- mining land uses, including: 1. Developed Water storage and, 2. Wildlife habitat Over the past fifteen years there has been a significant growth in the demand for water storage on the South Platte River. Sand and gravel extraction along the South Platte River from Thornton to Fort Lupton has presented Front Range municipalities with the opportunity to acquire important water storage needed to meet the demands of their growing populations. The Holton Lakes sand and gravel project offers the opportunity to create 4000 acre feet of new water storage for the citizens of Weld County. This new water storage could be used to provide much needed augmentation water for those in the agricultural community who rely on tributary ground water wells to irrigate their farms. 3 The second goal of the Holton Lakes reclamation plan is to add wildlife habitat diversity in the riparian corridor of the South Platte River. In addition, future trail alignment opportunities along the South Platte and from the City of Fort Lupton will provide important links to the greater South Plant River trail network both up stream and down stream from Holton Lakes. 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 and the zone district in which it is located. Answer: The subject property is zoned"A"Agricultural. The proposed use is allowed by Special Review pursuant to Sec. 23-3-40(A.)(4.) of the Weld County Land Use Code. 4. If applicable, explain what efforts have been made, in the location decision for the proposed use, to conserve productive agricultural lands in the agricultural zone district. Answer: The Holton Lakes Mining Plan is intended to allow the continued agricultural use of the property concurrently with mining. For example, mine stages 2-5 will remain in agricultural use up until mining begins in each of these stages. Ultimately 166 acres of the 298.5 acre Holton property will be converted to developed water storage. 6. What type of uses surround the site? Explain how the proposed use is consistent and compatible with surrounding land uses. Response: Currently, land uses surrounding the Holton Lakes property include agriculture, recreation and sand and gravel mining operations (past, present and future); they include: ■ West- Agriculture and future sand and gravel mining (see Lafarge's Riverbend sand and gravel pit which was recently approved by Weld County); • Northwest—Agriculture(pasture); • North- Agriculture and outdoor recreation; • East—Colorado State Highway 85 and the City of Fort Lupton; 4 • Southeast—Twenty acre farmstead with house and vacant land; • South—Agriculture/Pasture and future sand and gravel mining Mining Phase 6 of Lafarge's Riverbend sand and gravel pit is contiguous to the south boundary of mining Stage 4 of the proposed Holton Lakes pit. • Southwest- Mining Phase 6 of Lafarge's Riverbend sand and gravel pit is contiguous to the southwest boundary of mining Stage 4 of the proposed Holton Lakes pit. As historic South Platte sand and gravel resources between Brighton and Fort Lupton are depleted, demand for replacement aggregate reserves in the Fort Lupton area will continue to increase. The proposed Holton Lakes sand and gravel operation is compatible with both existing and future land uses in this area of Weld County. 7. A statement describing the existing land use. Response: A small portion of the Holton property was mined by the Colorado Department of Transportation and the sand and gravel was used for State Highway 52. The existing land use on the Holton Property is agricultural including pasture, livestock feed and vegetables. 8. Describe, in detail,the following: a. How many people (employees,visitors, buyers, etc.)will use this site? Answer: Depending on the number of shifts worked per day, the number of people using the site on a daily basis will range anywhere from 25 to 35. b. What are the hours of operation? Answer: All sand and gravel and concrete plant operations will be conducted during the hours of daylight except in the case of a public project or private emergency or to make necessary repairs to equipment. This restriction shall not apply to operation of administrative and executive offices or repair or maintenance facilities located on the property. 5 c. What type and how many animals, if any,will be on this site? Answer: Livestock (horses and cattle) will continue to be pastured on those areas of the subject property not being mined. d. What kind (type, size,weight) of vehicles will access this site and how often? Answer: The following vehicles will access this site on a daily basis: 1. Ready-mix concrete trucks (25 tons) 2. Sand and gravel haul vehicles (12-25 tons) 3. Cement bulk loaders (25 tons) 4. Employee vehicles, including cars and pick-up trucks e. Who will provide fire protection to the site? Answer: Fort Lupton Fire Protection District. f. What is the water source on the property? (commercial well or water district) Answer: Potable water will be supplied by commercial water service. The Applicant will use water from an existing well on the Holton Property for all operations including but not limited to: sand and gravel washing and processing; dust control and, ready mixed concrete production. An application for a commercial well permit will be filed with the office of the Colorado State Engineer. g. What is the sewage disposal system on the property? (Existing and proposed.) Answer: Following approval of this USR Permit Application by the Weld County Board of Commissioners, the applicant will apply to the Weld County Health Department for an ISDS Permit to serve the office/scale house, the sand and gravel processing plant and the ready mixed concrete plant personnel. Portable restrooms will be used to provide sanitary services for employees working at 6 the mine face in Stages 2, 3 and 4. h. If storage or warehousing is proposed,what type of items will be stored? Answer: The following materials will be stored on site: 1. Sand and gravel stockpiles 2. Cement and fly ash stored silos 3. Concrete add mixtures 4. Fuel, oil and grease i. Explain where storage and/or stockpile of wastes will occur on this site. Answer: Returned concrete will be wind rowed, allowed to harden, and recycled as structural fill and road base. j. Explain the proposed landscaping/screening for the site. Answer: The company proposes to landscape the north and east boundaries of the site with a combination of trees and shrubs as depicted on the landscape plan map included with this USR application package. k. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. Answer: It is estimated that construction and landscaping will require 3 to 4 months to complete. The first area to be landscaped is along the north side of mining Stage 1, adjacent to Colorado Highway 52. Landscaping work associated with Stage 1 will be completed during the first year following approval of this USR, and prior to the start of mining in that stage. Construction and landscaping work along mining Stages 2 and 3, adjacent to Colorado Highway 85 will begin after the Stage I landscaping work is completed. I. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Answer: To the greatest degree practicable, reclamation of the Holton Lakes Pit will be 7 concurrent with the mining of the site. Within two years of the completion of all mining activities on site and the termination of the USR all remaining reclamation work will be completed. m. Explain how the storm water drainage will be handled on the site. Answer: Storm water drainage will be managed according to the Storm Water Management Plan(SWMP), which will be developed for the site in conjunction with the requirements of the NPDES ground water discharge permit for sand and gravel operations issued by the Colorado Division of Health and Environment contained on site. If requested to do so,the Applicant will provide a copy of the NPDES Permit and SWMP for the Holton Lakes Pit to Weld County. n. Method and time schedule of removal or disposal of debris,junk and other wastes associated with the proposed use. Answer: Removal/disposal of debris,junk and wastes associated with the Holton Lakes sand and gravel operation will occur as needed during the life of the pit. Following completion of all mining activities, all plant, and equipment will be removed as well as all remaining debris,junk and wastes. o. A statement delineating the need for the proposed use. Response: Regional growth,transportation, and land use planning will all be affected by the ability of the aggregates (sand and gravel) industry to meet future demand for aggregate resources. Local demand for aggregates is expected to continue at reasonably high levels due to projected population growth and the associated demand for infrastructure improvements needed to accommodate such growth. Available aggregate resources are becoming more difficult to recover and more expensive to produce due to longer transportation distances, more involved permitting requirements, and the encroachment of other land uses on undeveloped potential aggregate reserves.

The aggregate deposit consists of alluvial sand and gravel overlain by topsoil and overburden. The topsoil layer and overburden layer will range from four to 6 feet in thickness, while the sand and gravel deposit is 15 to 25 feet thick. The deposit is underlain by bedrock shale. The maximum depth of excavation will be approximately 30 feet. The alluvial groundwater level lies approximately 3 to 5 feet below natural ground level. The deposit is therefore classified as a wet alluvial deposit. However, the sand and gravel deposit will be mined dry once the each mining stage has been de-watered. The sand and gravel deposit is cataloged in the report Sand, Gravel and Quarry Resources, Colorado Front Range Counties (Colorado Geologic Survey, 1974). An estimate of overburden and resource volumes for the property is as follows: Northwest Northeast Southeast Southwest Mining Stage (Stage 5) (Stages 1 & 2) (Stage 3) (Stage 4) Overburden(yd) 360,000 120,000 285,000 390,000 Resource(tons) 3,300,000 1,100,000 5,200,000 2,600,000 5.2 Mining Method Dry mining techniques will be used. Initially, a dewatering ditch will be excavated around the perimeter of each mining stage and groundwater recovered in the dewatering ditch will be discharged to the South Platte in accordance with Colorado/NPDES discharge permit regulations. Prior to dewatering mining stages 3, 4 and 5, a soil-bentonite slurry wall will be installed around the perimeter of each mining stage. Once the slurry wall in place the stage to be mined will be de-watered and mined. With the slurry wall in place prior to pit de-watering, adverse impacts to nearby groundwater wells will be avoided. r Topsoil and overburden will be placed in temporary stockpiles within the mining area limits. Topsoil and overburden will be salvaged and stockpiled separately. Approximate topsoil and overburden stockpile areas are shown on the Mine Plan Map. The deposit will be mined using scrapers and front-end loaders. Excavated sand and gravel will be discharged to a field conveyor system for transport to the on-site processing plant located in the north half of Stage 5. Additional conveyors may be used inside the mine areas to facilitate transport of the resource. Primary access to the Holton Lakes operation will be via an existing farm road from Colorado State Highway 52. In addition, operational access to Stages 2 and 3 will be via an existing farm road from Colorado State Highway 85, which will be used for mining equipment, service vehicles and employee access only. Haul trucks to and from the site will use Highway 52 only. The Highway 52 access road intersection with will be upgraded per C-DOT approved specifications and design. 5.3 Mining Schedule Mining is currently projected to occur at the rate of approximately 1.0 million tons/year. Based on an estimated reserve of 12 million tons, mining will be completed in approximately 12 years from the start of operations. Mining is currently projected to commence in 2010. 5.4 Surface Water Management All mine areas will drain internally. Uncontrolled releases of surface water and sediment from mining areas will not occur. Storm water collected in the open pit will be managed in accordance with Colorado/NPDES discharge permit requirements. Sediment generated from localized storm water runoff and surface drainage will be detained in the ponds created by the proposed mining operation. 5.5 Disturbance Areas Disturbance areas associated with the Holton Lakes Pit are estimated as follows: Mining Area Acres Stage 1 9.0 Stage 2 24.2 Stage 3 75.3 Stage 4 42.5 Stage 5(Including Processing and Concrete Plant) 52.6 Total Project Disturbance 203.6 Total Permit Area 298.5 The maximum area that will be disturbed at any point during the operation will be approximately 110 acres. HOLTON LAKES SAND AND GRAVEL PIT MINING AND OPERATIONAL STANDARDS 1. No excavation or processing of sand and gravel shall be permitted nearer than ten (10) feet to the boundary of adjacent property, irrigation ditch, or easement, nor nearer than 125 feet of an existing residence unless by written agreement the owners of such adjacent property consent to a lesser distance and the Planning Commission approves such lesser distance. The Planning Commission may set a greater distance than the above when justified. 2. All sand and gravel and concrete plant operations shall be conducted during the hours of daylight except in the case of public project or private emergency, or to make necessary repairs to equipment. This restriction shall not apply to operation of administrative and executive offices or repair or maintenance facilities located on the property. 3. Weeds and any other unsightly or noxious weeds shall be cut or trimmed as may be necessary to preserve a reasonably neat appearance and to prevent seeding on adjacent property. 4. Existing trees and groundcover along public road frontage and drainage ways shall be preserved, maintained, and supplemented if necessary for the depth of the setback. 5. All means of access to the property from any street shall be located and designated as to avoid the routing of vehicles to and from the property over streets that primarily serve residential development. 6. All access roads from the sand and gravel and concrete operations to public highways, roads or streets shall be paved or otherwise treated to minimize dust conditions of all parts of such access roads that are located within one-fourth mile of the public highway, road, street, or adjoining residential structure. 7. Prior to the start of mining,the property shall be fenced with three-strand barbed wire in order to keep out livestock from adjacent properties. In addition, chain link fencing will be installed along the south boundary of Colorado Highway 52 and along the west boundary of Colorado Highway 85. The perimeter of the property will be posted with"No Trespassing" signs. 8. Where topsoil is removed, sufficient arable soil shall be set aside for reclamation. 9. Rock crushers, screens, feeders, conveyors, concrete plant and all accessory facilities and equipment, as well as the exportation by conveyor of sand and gravel materials to adjoining, surrounding or nearby properties will be allowed. However, the operation of the concrete plant shall be subject to any additional conditions required by the Planning Commission and/or the Board of County Commissioners. The concrete plant shall meet the requirements of Article III, Section 23-3-40 of the Weld County Code 10. Conveyors, field hoppers, and similar accessory facilities and equipment, as well as the conveyance of sand and gravel materials from adjoining, surrounding, or other properties will be allowed. 11. The operator shall furnish evidence they are insured to the extent of not less than $100,000.00 against liability for any negligent act or omission by the operator from the operation or maintenance of the sand and gravel pit and the extraction and production of sand and gravel and all activities connected with or incidental thereto. 12. The use will not cause injury to vested or conditional water rights. In the event that the use may cause injury to vested or conditional water rights the applicant will either present 1) an agreement with the appropriate water conservancy district or water users group; 2) a plan of exchange or Substitute Water Supply Plan approved by the State Engineer or; 3) an Augmentation Plan approved by the District Court for Water Division No.1 which prevents injury to said water rights. 6.0 DMR&S RECLAMATION PLAN AND USR STANDARDS 6.0 DRM&S RECLAMATION PLAN 6.1 Post-Mining Land Use The entire Holton Lakes Sand and Gravel Pit are located in the 100-year floodplain of the South Platte River. Weld County Department of Planning Services considers land located in the 100-year floodplain to be suitable for agriculture, recreation, and wildlife uses. The post-mining land uses as proposed in this Reclamation Plan include developed water storage, passive recreation, and wildlife habitat. These uses are compatible with the surrounding land uses and with the Weld County planning goals. In order to minimize surface disturbance at the Holton Lakes Pit, mining and reclamation will be conducted concurrently to the greatest extent practicable. The operator will concurrently reclaim pit wall areas in locations where mining has been completed. Reclamation, including regrading and seeding will be completed in 2 to 3 years following the completion of mining operations in Stages 3, 4 and 5. Stage 2 will be reclaimed over the life of the mine and Stage 1 will be backfilled after Stages 3, 4 and 5 have been reclaimed. Stage 1 will be backfilled to approximate pre-mining elevations in order to provide the owners with the greatest degree of land use options following reclamation. Stage 2 will be backfilled, over the life of the mine, with wash fines from the sand and gravel processing plant. Wash fines will be pumped from the processing plant on the west side of the South Platte River to stage 2 on the east side of the River and used to backfill each of the three cells that comprise this stage. The goal of the reclamation plan for stage 2 is to enhance the wildlife habitat diversity of the river corridor. Stages 3, 4 and 5 will be reclaimed for developed water storage. Preliminary calculations indicate that approximately 4,000 acre-feet of water storage can be created with these three stages. 6.2 Reclamation Measures—Material Handling Site reclamation measures are illustrated on Exhibit F. Reclamation of the site will include creation of three slurry-sealed pits. All pit walls will be regraded using stockpiled overburden. Pit perimeter slopes will be no steeper than 3H: 1V. Topsoil will be spread over the surface of the regraded slopes in all areas above the post reclamation water storage elevation, and the topsoil-covered surfaces will be revegetated. Disturbed areas associated with site access and the existing conveyor will be scarified, covered with topsoil, and revegetated. Site grading will be performed to create stable topography that will be consistent with post-reclamation land uses. Reclamation quantities and costs are summarized in Exhibit L. 6.3 Water Because overburden and mine materials are inert, adverse impacts to local surface water or groundwater quality are not anticipated. The Applicant will comply with all applicable State water quality laws and regulations. 6.4 Wildlife Presently, Stages 4 and 5 are used for livestock grazing. Stages 1 and 3 are used for agricultural production and Stage 3 is fallow. There some indigenous wildlife species that inhabits the Holton Lakes property that will likely be displaced by the proposed mining activities. See the Wildlife Resources Assessment prepared by ERO Resources found in the Appendices to this permit application. 6.5 Topsoiling Soils on the Holton site consist of Weld-Colby, Loup-Boel and Dacono clay loam. These soils will be stripped and stockpiled during overburden removal, and retained for replacement during site reclamation. During reclamation, topsoil will be spread over areas to be reclaimed. Topsoil stockpiles will be protected from erosion and other damage by best management practices. Soil amendments are not expected to be required due to the nature of the soils. However, topsoil samples will be subjected to agricultural testing prior to reclamation to assess fertilizer requirements. SCS soil fertilizer recommendations, if any, will be followed. r 6.6 Re-vegetation Following topsoil replacement, reseeding will be performed according to SC S recommended practices. Based on SCS guidance for other local projects having similar soils,the following re-vegetation procedures are anticipated: • Grass seed will typically be planted in unfrozen soil between October 1 and April 30. • Grass seed will be planted with a grass drill or, where necessary, with a broadcast seeder. • The proposed seed mix and application rates in pounds of pure live seed per acre are described on the following pages. • If necessary, critical areas may be covered with straw or hay mulch to control erosion during germination. • Weed-control practices will be implemented as required. The above procedures may be modified as conditions dictate. In areas that are peripheral to the Stage 2 wetlands, marsh and aquatic plants will establish themselves. The types of wetland plants anticipated to colonize Stage 2 include cattails, willows, cottonwoods, and bull-rushes. 6.7 Buildings and Structures Prior to the completion of mining Stage 5,the sand and gravel processing plant and ready mixed concrete plant will be removed along with all associated structures such as equipment repair facilities and related structures if any. As mining in Stage 5 is completed, all field conveyors will be removed including the wash water pipeline from the processing plant to Stage 2. Finally, the scale house and administrative building will be removed along with any other related structures. The overland conveyor system required for transport of sand and gravel to the process area is portable. 6.8 Proposed Seed Mixes Seed Mix for Upland Areas (Reseeding) Species Common Name—Variety Rate* PLS lb/ac GRASSES Agropyron dasystachyum Thickspike Wheatgrass—Critana 1.7 Agropyron smithii Western Wheatgrass—Ariba 2.4 Agropyron trachycaulum Slender Wheatgrass— San Luis 0.05 Andropogon gerardii Big Bluestem—Pawnee 0.5 Bouteloua curtipendula Sideoats Grama—Butte 0.8 Bouteloua gracilis Blue Grama—Alma 0.2 Buchloe dactyloides Buffalograss—Top Gun or Native 2.9 Panicum vrgatum Switchgrass—Nebraska 28 or Trailblazer 0.4 Poa ampla Big Bluegrass—Sherman 0.2 Poa canbyi Canby Bluegrass—Canbar 0.1 Schizachyrium scoparium Little Bluestem—Blaze 0.6 Stipa viridula Green Needlegrass—Lodorm 0.6 FORBS Achillea lanulosa Western Yarrow—Native 0.02 Linum lewisii Perennial Blue Fax—Appar 0.1 Rudbeckia hirta Black-eyed Susan—Native 0.03 10.60 *PLS =Pure Live Seed; Rates shown are for drill seeding; if broadcast seeded, rates should be doubled.

As you are aware, the Holtons submitted three Petitions for Annexation to the Fort Lupton City Counsel on May 3, 2006, for parcels of land described as Holton Lakes First, second and Third Annexations. On September 13, 2006, the Fort Lupton City Counsel approved an Annexation Agreement related to the Holtons' Annexation Petitions, which included terms and conditions which are unacceptable to the Holton. Please consider this letter as a formal withdrawal of the Holtons' three Petitions for Annexation filed with the City of Fort Lupton on May 3, 2006.

While the property is located in unincorporated Weld County it is also in the City of Fort Lupton's Urban Development Area which gives the City the option to annex and permit the Holton property for sand and gravel mining. Last Wednesday night, September 13,2006 the Fort Lupton City Council voted at annex the Holton property subject to the execution of the City's Annexation Agreement. Among the terms and conditions of that Agreement is a requirement that the "Owners"pay an annual impact fee over the life of the operation to the City in the amount of 1%of the gross annual revenue from the sale of sand and gravel, which requirement is not acceptable to Tom Holton.The City has given the Holtons until October 4, 2006 to accept or,reject their conditions of annexation and withdraw their petition for annexation. The purpose of this e-mail is to confirm that if Holton rejects the City's Annexation Agreement and withdraws his petition to annex he will then be free to immediately apply to Weld County for Use by Special Review(USR) approval to mine his property. Assuming that to be the case, Tom and I would like to schedule a meeting with you at your earliest convenience to discuss how best to proceed with a USR Application. If this is not the case please advise accordingly.

The 320 acre site is located in Sections 6 and 7, of T1N, R66W in un-incorporated Weld County. The property is bounded by Highway 52 on the north, Highway 85 on the east, and is bifurcated by the South Platte River flowing south to north. The land is currently being farmed for hay and pasture. For purposes of this analysis and probable future mining limits, the property is evaluated by four quadrants (northwest, southwest, northeast and southeast), as defined by the South Platte River and the Excel Energy electrical transmission line that crosses the property east to west. Exploration,Sampling and Testing Exploratory drilling occurred on July 19-21, 2003, with Layne-Western's dual-wall percussion drill (6-inch inside diameter). Drilling was supervised by yourself,and continuous samples were obtained for testing. The locations of the twenty-six drill holes are indicated on the attached map. The samples were later visually classified by CTS, and composite samples were field split from bucket samples of eight drill holes for gradation testing. Gradations of the various samples tested are listed in the attached Aggregate Gradation Summary, with the average property gradation presented below. Large cobbles were encountered during the drilling, as evidenced by the drill logs and some fractured cobble samples, but these larger materials could not be retrieved through the 6-inch drill stern. Samples were not tested for aggregate quality; however the South Platte River deposit has a history of producing acceptable quality products.

The average thicknesses of overburden and net deposit (sand & gravel, less :lay lenses) were first determined from the various drill holes representing each area. The net recoverable tons per mineable acre for each area was then calculated, using a ten percent waste factor for stripping and processing. A probable effective mining limits is shown on the map, considering typical mining set-backs from major pipelines, roads and structures. The set-backs utilized are summarized below. • 200 feet from South Platte River • 100 feet from oil and gas wells • 100 feet from towers of the power transmission line CONSTRUCTION TECHNICAL SERVICES,INC. Jan 27 05 10: 06a A. 3 Tom Holton—Fort Lupton Property Evaluation TH 03-196 Aggregate Reserve Analysis and Preliminary Water Storage Estimate • 100 feet—existing width of easement of the power transmission line • Highways 85 and 52—75' from ROW fence(50' minimum at grade) • Big Dry Ditch—50 feet at grade • Oil Tank Batteries—50 feet at grade • Other property lines—50 feet(15' to slurry wall, 20' from slurry wall,excavation slope) The property is reported to consist of 320 acres. When comparing the Weld County Assessor's map with the CDOT Right-of-Way survey information we obtained, it appears the net useable property is approximately 313 acres. CDOT has a 60' wide ROW, south of the centerline of Highway 52, consisting of approximately 3.5 acres. CDOT's survey also indicates a triangular parcel of approximately 3.3 acres for the southbound on-ramp to Highway 85. The mining areas were based on the assumption that the minor on-site oil gathering lines will be relocated, and leaving well sites and tank batteries alone. Other areas of the property might be able to be mined, but were considered potentially mineable for the purpose of this evaluation, and are discussed below. The actual bank of the South Platte would require evaluation of normal high-water flows, compared to actual elevations. The six sand bars along the river might be determined to be outside the normal river channel. Similarly, the mining othets might be reduced to 100 feet, if sufficient river bank and/or pit side stabilization occurs(at some additional costs). The Big Dry Ditch might be relocated into a 100-foot wide easement adjacent to the south side of the power transmission easement. The houses in the property's northwest corner could be removed, to allow mining and increased water storage. Finally, the power company might allow mining and concurrent backfilling to grade of the 100 foot easement between towers. These potential mining areas, acreages and conesponding tonnages are summarized below. rPotential Mining Area Acres S& G Depth I Reserve Tonnage.

Based on these values, approximately 60.000 tons had been removed. This amount was deducted from the reserve estimates reported for the northwest area. Preliminary Water Storage Estimates Preliminary water storage was estimated,assuming 3' of freeboard, 3:1 reclaimed pit slopes, with water surface elevation controlled by the natural low point of each area. Elevations were obtained by a hand-held GPS reading at each drill hole location. The net water storage is also CONSTRUCTION TECHNICAL SERVICES,INC.

Preliminary water storage estimates (without perimeter elevation changes, or allowances for processing fines volumes) range from 3300 to 3800 acre-feet. Since the volume of the northeast mining area is approximately ten percent of the total mined volume (also equal to the assumed processing waste factor), this area might be best mined without a slurry wall, and hydraulically badcfilled to grade. A suitable land use requiring limited daily vehicle trips (for highway access)might be the best reclaimed land use of this part of the property.

We felt that our meeting was useful in helping us gain a better understanding of CDOT's concerns related to Ready Mix Concrete Company's (Ready Mix) Holton Lakes sand and gravel mining and reclamation plans and what we can do to address those concerns. I trust our meeting was equally useful for you and Joe. As a follow up to our meeting, on Monday, July 2, 2007 Mike spoke to Erica Crosby with the Colorado Division of Reclamation, Mining & Safety (DRM&S) about our meeting and the various items that Ready Mix committed to CDOT to do and how best to incorporate those changes in the Holton Lakes Mining and Reclamation Plans. Because of Mike's conversation with Erica, we will make the agreed to revisions to the Mining and Reclamation Plans and get them to the Division and you next week. Specifically, Ready Mix has committed to make the following revisions that we discussed at our meeting last Friday: 1. In order to protect the setback area between the South Platte River and the north end of mining Stage 2-C, Ready Mix will install approximately 500 feet of riprap on the pit side of the north area of mining Stage 2-C. Riprap will be installed as soon a mining in the north end of Stage 2-C has been completed. Please note: Stage 2 will be backfilled over the life of the mine and re-vegetated (see enclosed photograph), which will serve to mitigate erosion due to flooding. The re-vegetated wash fines settling ponds shown in enclosed Pictures 1 and 2 are located adjacent to the west side of South Boulder Creek. Floodwaters from South Boulder Creek have previously inundated the backfilled area without causing any erosion damage. Other Boral Companies Include Boral Best Block LLC/Boral Construction Materials LLC/Ready Mixed Concrete Company Mr. Gary DeWitt July 9, 2007 Page Two of Five 2. In the event that Ready Mix is able to mine up to 200 feet from the South Platte River,the Company will install two (2) side channel spillways between the South Platte and mining Stage 2. One spillway will be constructed opposite the south end of Stage 2-A and one opposite the north end of Stage 2-C. The spillways will be constructed of poured in place concrete cut-off walls and riprap in a manner similar to the side channel spillway recently constructed at Aggregate Industries Thornton Pit, located on the west side of the South Platte River immediately south of East 104`s Ave. (see enclosed photographs 3 and 4). 3. Ready Mix will install the mining Stage 3 slurry wall at a minimum distance of 100 feet from the west right-of-way line of Highway 85. 4. Ready Mix will install the mining Stage 5 slurry wall a minimum distance of 100 feet from the west right-of-way line of Highway 52. 5. Last Tuesday,July 3 the company installed a ground water monitoring well along the west side of Highway 85,between the ROW and mining Stage 3, opposite the location of the east slurry wall for Stage 3. The company will collect monthly baseline ground water elevations opposite Highway 85 prior to the installation of the Stage 3 slurry wall and after the wall in installed. Ready Mix also installed a ground water monitoring well between the Highway 85 ROW and mining Stage 2. Ground water elevation data will be collected monthly at all monitoring wells. 6. Following installation of the Stage 3 slurry wall,the company will construct a cut-off ditch between the west ROW line of Highway 85 and the Stage 3 slurry wall. The cut-off ditch will be designed to carry water to Stage 2. This water will be incorporated into the reclamation plan for that stage. Regarding your concern about the operation of the Holton Lakes water storage reservoirs after the reclamation bond is released by the State, at this time we do not know who,what,where and how the reservoirs will be operated post reclamation. Water may or may not be discharged directly from the reservoirs to the South Platte River. In the event that the future operator of the reservoirs elect to discharge water directly to the River, at the very least we believe that the State Engineers Office, the Water Mr. Gary DeWitt July 9, 2007 Page Three of Five Commissioner for this section of the River and the U.S. Army Corps of Engineers would all likely be involved,to one degree or another, in determining the how, when and where water would be released to the River. Gary,please do not hesitate to call me at(303)668-1751 if you have any questions regarding this letter or any additional concerns that you have regarding our project.

DRM&S Adequacy Review Comments and Applicant's Response as follows: 1. The Division was unable to locate the proof of notice to the Colorado Department of Transportation (CDOT). As required by Rule 1.65(2),please submit the proof of the public notice circulated to CDOT. Proof of notice may be return receipts of a Certified Mailing or by proof of personal service. Applicant's Response: The Applicant previously supplied the Division with"proof of notice"consistent with the requirements of Rule 1.6.5 (2). Rule 1.6.2(1 Xe)requires Section 112 permit applicants to mail or personally serve a copy of the notice specified in Rule 1.6.2(1Xd)immediately after the first publication of the notice to: (i) all"Owners of Record'of the surface and mineral rights of the affected land; and(ii)the"Owners of Record'of all land surface within 200 feet of the boundary of the affected lands. Rule 1.1(34)defines the term "Owner of Record'to mean"the owner or owners of a surface property interest shown on the records of the County Assessor as of the date of filing." Attachment A to this Adequacy Response is a certified list of owners of record according to the Weld County Assessor obtained for purposes of fulfilling the Rule 1.6.2(1 Xe)public notice requirement. Since CDOT was not on the certified list supplied by the Weld County Assessors Office, CDOT is not an"Owner of Record'as defined in Rule 1.1(34)and CDOT was not provided notice of the Section 112 permit application for the Holton Lakes project. Furthermore,the Division indicated that since CDOT"owns"a permanent manmade structure within 200 feet of what would be the affected land in this case,CDOT should have been noticed. This position is not supported by Rule 6.4.19. The Applicant has,however,notified CDOT,Attachment B includes copies of the letter,notice and return receipts). Therefore, while the attached confirms that notice of the application as specified in Rule 1.6.2(1Xd)has been supplied to CDOT,the Applicant both: (a) objects to the DRMS requiring such notice be made;and(b)it reserves the right to raise the issue at the pre-hearing conference for consideration by the pre-hearing officer and for consideration by the Board at any required public hearing. 2. Rule 62.1(2) requires that maps be signed by a registered land surveyor,professional engineer, or other qualified person. The revised maps submitted to the Division were not signed. Please resubmit a signed copy of the maps. Applicant's Response: All revised maps have been signed per Rule 6.2.1(2) and are included with this Adequacy Response. Rule 6.4.4 Exhibit D-Mine Plan 3. In regard to the topsoil and overburden piles, Exhibit D depicts the piles within each of the mining stages. Please explain if the piles will be stockpiled prior to mining an area, or if they will be stockpiled on the floor of the particular stage. In addition, the Division recommends that if piles will be stockpiled for longer than one year, they should be revegetated with the temporary seed mature. Please state the temporary seed mixture that will be used on piles and the rate and method to be applied Applicant's Response: Topsoil and overburden will be stockpiled on the surface of the active mining stage.The Applicant will seed stockpiles left in place for longer than one year using the following seed mix.

The applicant states that the on site fuel station will be designed to contain 100%of all stored fuels and lubricants. Please further clam of the general construction plans for the fuel station (Le. concrete pads, berms) and how the structure will be secured to prevent movement of the facility in the event of a flood event. Applicant's Response: The fuel station will be a single concrete structure consisting of concrete walls and concrete floor secured with eight 36"concrete footings around the perimeter of the station. The dimensions of the fuel station will be 30 feet by 15 feet with 4-foot high concrete walls. .— Rule 6.4.5 Exhibit F-Reclamation Plan 2 5.

Price subject to change without notice. 3 --6. The Division will need to include a cost for installation of the slurry wall(s)around the various phases. Please inform the Division of the sequence of installation of the three slurry walls. For example, the applicant can provide a reclamation bond for the installation and maintenance of all three slurry walls, or provide a reclamation bond for the largest area to contain a slurry wall(or worst case scenario)with the commitment that other slurry walls will not be installed until the first one has been approved by the Office of the State Engineer(OSE) (or that the Division retain a 20%bond until approved by the OSE). Please refer to the Slurry Wall Guidance document located on our web page at http://mining.state.co.us/. Applicant's Response: Mining Stage 3 will be slurry sealed first,followed by slurry sealing of mining Stages 4 and 5. All three slurry walls will be installed prior to the start of de-watering and mining in a specific mining stage. Based on our conversations with you,the Applicant is aware that the Division has proposed two reclamation bonding options pertaining to the slurry wall installation. The Applicant has also reviewed the Divisions March 29,2000"Policy on Application Reviews Involving Sand and Gravel Pits"and proposes the "Regulated Construction Option"as provided immediately below. The Applicant will provide design drawings and specifications for the installation of the slurry wall along with a quality assurance/quality control(QA/QC)plan. These documents will be binding under the terms of the permit and,once approved,they will be subject to change upon approval from the Division. The Applicant will advise the Division of the slurry wall construction schedule and provide the Division with an"as built"construction report detailing the installation of the slurry wall, including narrative descriptions of any installation problems that occurred,and the results of any testing that was conducted under the approved QA/QC plan. The Applicant agrees to provide the Division with a statement from the QA engineer,or similarly qualified person,that the slurry wall was constructed in accordance with the approved plans and specifications. Based on the level of regulatory control over the installation of the slurry wall described above, the Applicant proposes to post bonding for repair and/or replacement in an amount equal to 20%of the total linear feet of slurry wall installed or approximately 2,200 feet. Rule 6.4.7 Exhibit G- Water Information 7. The Applicant proposes a temporary mining only setback from the South Platte River of 100 feet for Stages 1 and 2 and a 400 foot setback for Stages 3, 4 and 5. It is the Division's position that riverbank armor is required prior to mining for any portion of river bank where mining will occur within 400 feet of the riverbank. However, the Division may waive this requirement for those portions of riverbank that are currently stable, and are characterized by gentle bank slopes and well established riparian vegetation. The applicant states that for Stages 1 and 2 the 100-foot mining setback is "temporary"because following mining, the area will be backfilled to within 2 to 3 feet of the pre-mining surface. The Division reviewed the "Flood Hazard Permit Application Holton Lakes Sand and Gravel Pit"application and it is stated that Stages 1 and 2 will be backfilled to approximate pre-mining grades over the 8 to 10 year life of the mine. For Stage 1 a seven foot high flood control berm is located between the east side of stage 1 and the South Platte River. In addition, much of this bank is currently rip-rapped. However, the applicant will need to commit to immediately reclaiming the eastern bank of Stage I once mining in this area is complete. However for Stage 2, there is no flood control berm or extensive river armoring along the shoreline. In order to mine within 100 feet of the river in Stage 2, the applicant will need to commit to mitigation measures that contain a combination of the following suggestions; mining dry pit slopes at a maximum of 1:1, backfilling 4 the areas closest to the river before the corresponding spring runoff(April of the following year), and/or _. armoring reclaimed pit slopes in close proximity to the South Platte River with erosion control riprap. Inlet and outlet structures are noted in Stage 2, however, designs were not submitted for these structures. Please provide further information on the interim mitigation measure of the western slope of Stage 2 and provide the designs for the inlet and outlet structures. Applicant's Response: The Applicant commits to immediately reclaim the eastern bank of Stage I once mining in this area is completed,as provided in the second paragraph of Adequacy Comment# 7 immediately above. In addition,at this time the Applicant proposes a 400 foot mining setback from the South Platte River for Stage 2.(see Attachment C) As previously discussed with Division staff,the Applicant may, at some future date,seek a technical revision(TR)to the permit to reduce the 400-foot riverside setback for Stage 2. The Applicant will,at that time,provide the Division a detailed mitigation plan consistent with the above comments at the time that a TR is submitted to the Division. 8. Please be aware that any reduction of elimination of the ground water monitoring plan for the Holton Lakes site will need to be requested by the operator in the form of a revision to the permit and approved by the Division. Applicant's Response: So noted. 9. The applicant states, "If possible, the applicant will collect 12 months of data prior to the start of dewatering operations, but it cannot commit to delay the start of dewatering." In order to obtain a seasonal baseline of the groundwater elevations in the area, 12 months worth of water levels must be obtained. Applicant's Response: The Applicant will collect 12 months of ground water levels prior to the start of pit dewatering. 10. The applicant states, "If possible, the applicant will pump ground water from Stage 2 as part of the pit dewatering into an area adjacent to the trees opposite the southeast boundary of Stage 2." If the applicant is unable to pump water to the cottonwood trees from Stage 2,please state how trees will be protected from the adverse impacts of pit dewatering. Applicant's Response: The Applicant will pump water from Stage 2 to the trees in the area opposite the southeast boundary of Stage 2. 11. The applicant states that monitoring wells will be filled with sand and gravel and closed in conformance with the requirements of the OSE. Please further specify how the wells will be reclaimed in accordance with OSE requirements. Attached is a copy of the Water Well Construction Rules that may be of use. 5 Applicant's Response: All monitoring wells will be reclaimed in accordance with the requirements of Rule 16.2.of the Office of the State Engineer(see Attachment D). Rule 6.4.19 Exhibit S-Permanent Man-Made Structures 12. The applicant proposes to mine through gas/oil lines in Stage 5 and possibly relocate some utility lines. Until such agreement is submitted and approved by the Division, the applicant will need to maintain the 100' mining off-set distance from the gas and power lines. If such notarized agreements cannot be achieved during this review period, then a revision to the permit will need to be filed prior to relocating the structures. Applicant's Response: The Applicant will maintain a 100-foot mining set-back from gas and power lines until such a time as notarized agreements with the appropriate utilities are provided to the Division,or,consistent with Rule 6.4.19,an appropriate engineering evaluation that demonstrates that such structures shall not be damaged by activities occurring at the mining operation is obtained. 13. It does not appear that the applicant and Kerr-McGee have entered into a Surface Use Agreement(SUA)for the site. Based on information obtained from other mining operations with oil/gas wells, a 150-foot mining off set distance from all existing oil/gas wells has been established not only for protection of the structures but also to allow access, storage and maintenance of the well. The applicant will need to either maintain a mining off set distance of 150 feet from all existing oil/gas wells,provide a notarized agreement to mine closer than 150 feet(SUA)as required by Rule 6.4.19 or provide a more through site specific geotechnical analysis that justifies the 100 foot mining off set distance. Please revise the text and maps accordingly. Applicant's Response: Rule 6.4.19 applies, in pertinent part,: "Where the mining operation will adversely affect the stability of any significant, valuable and permanent man-made structure located within two hundred (200)feet of the affected land..."The Division has no evidence to support any claim that the proposed Holton Lakes sand and gravel mining operation"will adversely affect the stability of any significant, valuable and permanent man-made structure located within two hundred(200)feet of the affected land..."To the contrary, the administrative record indicates that the Applicant previously submitted a letter report to the Division prepared by Mr.M.Edward Glassgow,PE and Professional Geologist,addressing geologic slope stability at the Holton Lakes site in the context of mining,man-made structures and mining set-backs. Mr. Glassgow's report was prepared pursuant to the requirements of Rule 6.4.19(b). To date, Division Staff have not articulated any specific deficiencies with Mr. Glassgow's work,or his professional credentials. The Division's reliance on information from other mining operations is wholly inappropriate given the site- specific analysis the Applicant has supplied in conformance with Rule 6.4.19(b). 14. The applicant states that there will be a 50 foot off set from Highway 85 and Highway 52 from the established right of way. Due to the proximity of the pits to the highways, the 100 foot mining off-set will need to be established and maintained from the right of way of Highway 85 and 52. If the applicant intends on mining any closer to the right-of-way, then a more through site specific geotechnical analysis will need to be provided. Please revise the text and maps accordingly. 6 Applicant's Response: In a letter dated June 4,2007 that was supplied by the Colorado Department of Transportation (CDOT),to Erica Crosby, DRM&S,CDOT stated: "The Vicinity Map in the application package shows a buffer zone between the start of excavation and the adjacent CDOT Right-of Way. It shows fifty feet between the top slope of the excavation and US highway 85 ROW and one-hundred foot buffer between top slope of the excavation and SH 52. We consider these to be the minimum widths of virgin undisturbed Around needed between the excavation and the ROW in this area. No excavation, including the slurry walls should be allowed inside these buffer areas." As stated above in CDOT's words,the mining setbacks adjacent to State Highways 52 and 85 proposed by the Applicant are acceptable to CDOT. In addition,to meet CDOT'S "virgin undisturbed ground"criteria,the Applicant agrees to construct slurry walls outside the limits of the setback distances of 100 feet along Highway 52 and 50 feet along Highway 85. Based on this,there is no basis for the Division to ignore CDOT's express confirmation that(a)the Applicant's proposed set backs are acceptable and(b)that the Applicant is meeting the"virgin undisturbed ground"criteria CDOT articulated. Furthermore,as mentioned above,Rule 6.4.19 is predicated on circumstances"Where the mining operation will adversely affect the stability of any significant, valuable and permanent man-made structure located within two hundred(200)feet of the affected land... " The Division has no evidence to support any claim that the proposed Holton Lakes sand and gravel mining operation"will adversely affect the stability of any significant, valuable and permanent man-made structure located within two hundred(200)feet of the affected land... " To the contrary,the administrative record in this case includes the letter report the Applicant filed with the Division,prepared by Mr.M.Edward Glassgow,PE and Professional Geologist,addressing geologic slope stability at the Holton Lakes site in the context of mining,man-made structures and mining set-backs. Mr. Glassgow's report was prepared pursuant to the requirements of Rule 6.4.19(b). To date, Division Staff have not articulated any specific deficiencies with Mr.Glassgow's work regarding mining setbacks and pit slope stability,or his professional credentials. In addition,the June 4,2007 CDOT comments do not contradict the Mr. Glassgow's report. 7 ATTACHMENT "A" CERTIFIED LIST OF OWNERS OF RECORD C AFFIDAVIT OF INTERESTED LAND OWNERS SURFACE ESTATE Subject Parcel: 147106300002 THE UNDERSIGNED,states that to the best of his or her knowledge the attached list is a true and accurate list of the names,addresses,and the corresponding Parcel Identification Number assigned by the Weld County Assessor of the owners of the property(the surface estate)within 500 feet of the property being considered.

DRM&S Adequacy Review Comments and Applicant's Responses as follows: 1. As required by Rule 1.6.5 (2),please submit the proof of the public notice circulated to all owners of record of surface lands, and easement holders that are on the affected land and within 200 feet of the boundary of the affected land Proof of notice may be return receipts of a Certified Mailing or by proof of personal service. Applicant's Response: See attached Certified Mail return receipts. 2. The Division received comments from the Colorado Historical Society and the Army Corps of Engineers and the Office of the State Engineer. The letters are attached Please address the comments noted in the letters, and make any changes in the application as necessary. Applicant's Responses: a. Colorado State Historic Society: In the event that human remains are discovered during mining activities, the applicant will adhere to the requirements under C.R.S. 24-80-1301 et seq. pertaining to unmarked human graves, as provided in the comment letter from the Colorado State Historical Society. b. Corps of Engineers: The Holton Lakes sand and gravel mining operation does not contemplate impacting any jurisdictional waters of the United States, including wetlands. c. Office of the State Engineer: Following approval of the Holton Lakes reclamation permit, the applicant will obtain the necessary well permit and approved Substitute Water Supply Plan from the SEO. Rule 6.4.4 Exhibit D-Mine Plan 3. Please indicate the pit mining slopes and the direction of mining on one of the exhibits. Applicant's Response: As provided on the revised Exhibit D, the finished pit mining slopes will be 3:1. During mining, pit slopes will range from 1.5:1 to 3:1 the direction of mining will be south to north in stages 2-5 and east to west in mining stage 1. 4. The applicant states that "all 5 mining stages will be dewatered and dry mined with backhoes and front end loaders. " During the pre-operation inspection it was discussed that areas that were not lined with a slurry wall would be wet mined(i.e. no dewatering would occur). Please clarify which pits will be dry mined vs. wet mined Applicant's Response: All five mining stages will be dewatered prior to mining. Mining stages 3-5 will be slurry wall sealed prior to dewatering. Stages 1 and 2 will be dewatered but not sealed prior to dewatering. 5. Portions of the application text state a permit area of 295 acres,yet other portions of the text and the application form state a permit area of 298.5 acres. Please clarify this discrepancy. Applicant's Response: The permit area, as indicated on the Reclamation Permit Form is 298.5 acres, which represents the total acreage owned by the Holton Family, LLC and which is intended to be permitted acreage. The application text states"The proposed permit area covers approximately 295 acres" which was rounded down from the actual permit area of 298.5 acres. For purposes of clarity, the reference to 295 acres should be 298.5 acres. 6 Under section 5.5 of the application, the acres of the various stages do not match up with the acreages noted in Exhibits D and F, as illustrated below. Please clarjb, the discrepancies of the acreages in the text and the exhibits. Mining Area Acres (noted in 5.5) Acres (Exhibit D) Acres (Exhibit F) Stage 1 9.0 8 Stage 2 24.2 22.1 Stage 3 75.3 75.5 73.7 Stage 4 42.5 42.0 40.8 Stage 5 52.6 52.8 52 Applicant's Response: 2 The acreage noted in Section 5.5 of the Permit application, entitled"Disturbance Areas," represent the approximate aerial extent of each mining stage. The total acreage of Stages 1-5 on Exhibit D (i.e.,the Mine Plan) vary by 0.10 acre from the total acreage reported in Section 5.5 of the application. The acreage described in Exhibit F (i.e.,the Reclamation Plant) reflect the aerial extent of the reclaimed areas in relationship to the associated post reclamation use. For example, the post reclamation land use of Stage 2 is"Wildlife Habitat, " which is anticipated to be 2.1 acres less than the estimated Stage 2 mining area of 24.2 acres. Similarly, stages 3-5 once reclaimed for water storage will be slightly smaller then the area mined. This should explain the difference in acreage totals that were noted in the adequacy comment and the bases for the differences. 7. Please provide additional detail and designs on construction of the slurry wall. In particular,please further explain the key dimensions of the slurry wall, depth of the slurry wall and how the slurry wall will be constructed around the gas/oil lines and wells. Applicant's Response: As detailed in the in the appendices (see Exhibit U-1)to the Holton Lakes 112 Permit Application, the Soil-Bentonite Slurry Walls will be built by excavating a trench approximately 3 feet wide to a depth of approximately 35 feet. The bottom 5 feet of the trench will be excavated into bedrock to create a seal between the sand and gravel alluvium and the pit floor(bedrock). The narrow trench will be filled with mixture of soil and bentonite, which, when set, forms the slurry wall. Currently, there are two buried gas lines in Stage 5 that will be relocated prior to the construction of the slurry wall for that mining stage. Prior to construction, all buried gas/oil lines will be relocated such that no lines will intersect the alignment of the slurry wall. 8. A review of the Exhibits and text provided by the applicant indicates that the pit edge is 100 feet from the south bank of the St. Vrain River. The exact location of the slurry wall between the lake edge and the bank of the river is unknown. Please provide a structural analysis that verifies the minimum width or buffer of soil needed on either side of the slurry wall to provide adequate support during saturated soil conditions, as well as under a rapid drawdown scenario. Applicant's Response: The slurry wall sections opposite the South Platte River in Stages 3-5 will be setback from the river a minimum distance of 125 to 150 feet. (see revised Exhibit D- Mine Plan attached). For adequate slurry wall support in the pit,the slurry wall contractor recommends a minimum distance between the slurry wall and the top edge of the pit of 25 feet. During mining the slope of the pit wall will vary from 1.5:1 to 3:1. All reclaimed slopes opposite the slurry wall (i.e., on the pit side)will be compacted backfill to a minimum slope of 3:1. 9. The applicant proposes to install a conveyor structure across the South Platte River. Please provide additional information regarding the conveyor structure (i.e. composition, length, width, height, foundations, etc.) and a specific plan for reclamation of the conveyor structure. If applicable,please provide documentation for the legal right to enter the easement associated with the conveyor structure across the South Platte River. 3 Applicant's Response: The conveyor structure spanning the South Platte River will be constructed of steel with an approximate span of 300 feet supported by two (2)40 foot high towers, one on either side of the river. Each tower will rest on two (2) 36-inch concrete caissons installed to a depth of eight(8) feet into bedrock(total depth of 38 feet). The conveyor belt structure will be eleven (11) feet wide and approximately five (5) feet above the elevation of the 100-year floodplain or the top of the bank on either side of the river,whichever is greater. The river corridor is on property owned by the Holton Family, LLC. As such no legal right to enter is required beyond that already conveyed to the Applicant and provided with these responses. 10. Rule 3.1.9(3) requires that topsoil stockpiles be stored in places and configurations to minimize erosion and be located in areas where disturbance by ongoing operations will be minimized. The overburden and topsoil piles are located within the mining boundaries of the various stages. Please explain how the topsoil and overburden piles will be protected from the active mining operation. Applicant's Response: Based on the mining plan, stockpiled overburden and topsoil will be used to reclaim the pit perimeter as soon as enough sand and gravel has been excavated from a given stage to accommodate the backfill necessary to create 3:1 slopes. While this method alone should be sufficient to address the Division's concern, in the event that excavated overburden and topsoil is stockpiled for more than 2-years,the stockpiles will be vegetated as necessary to preserve the overburden and topsoil needed for reclamation. 11. Please describe all haul roads that will be utilized for the mining operation. Rule 6.3.3(g) requires the applicant to specfr the dimensions of any existing or proposed roads that will be used for the mining operation. Any improvements necessary on existing roads and the specifications to be used in the construction of the new roads needs to be described in the permit and included as part of the permitted acreage. The applicant will also need to address reclamation of any new or improved roads constructed on site. Applicant's Response: All roads used by the Applicant are included within the permitted acreage. Temporary roads located within the perimeter of a mining stage will be excavated(i.e., removed) as part of the mining process. Existing on-site farm roads will be used for mining operations. These roads are approximately 25 feet in width. The only road improvements contemplated involve approximately 300 feet of the existing access from State Highway 52, which will be paved with concrete and left for the owner's use following completion of reclamation. A portion of the existing farm road located opposite the southeast corner of mining Stage 5 will be relocated to accommodate mining. None of the existing farm roads used by the applicant will be removed (reclaimed)as a condition of the reclamation plan. 4 j2. Please list and locate on the applicable exhibit all structures that will be constructed on site (i.e. plants, offices, trailers, tanks,fueling station structures etc...) and provide their associated dimensions and composition in order to accurately estimate a cost for removal in the reclamation bond estimate. Applicant's Response: The Mine Plan drawing provided in the Permit Application(i.e., Exhibit D) locates the structures that the Applicant proposes to construct on site including. Those structures will be of the following approximate dimension: • Scale (11'x 70'- steel with a concrete deck installed in a concrete box); • Scale house and office (20'x 36' portable building); • Employee and visitor parking (24'x 50' concrete slab on grade or gravel base); • South Platte River conveyor crossing(see response to number 9 above); • Portable sand and gravel processing plant and stockpile conveyors (60'x 60' x 1' reinforced concrete slab) • Portable concrete plant(40'x 40' x 1' reinforced concrete slab) • Truck washout structure ( 10'x 50'x 6'-4 cell concrete structure with concrete floor plus two (2)4'x 4' x 1' concrete slabs); • Fueling station(15'x 30'x 4' concrete structure with concrete floor)and, • Wheel wash (11'x 60'x 0.5' concrete basin) All structural dimensions are approximations only. Once the Applicant has secured all permits and approvals necessary to proceed with mining and reclamation at the Holton Lakes site, detailed site development plans will be prepared including specifications for all structures. That stated, the above dimensions should be sufficient for reclamation bond calculation purposes. 13. What protection measures will be used to ensure that spills of asphalt and/or concrete materials will not contaminate the surface or ground water? Will concrete trucks be washed-out on site? If so what measures will be taken to contain the wash water? In the event of a spill, what measures will be taken to capture the spilled fuels/lubricants. Any protective berms should be designed to contain 100%of the volume of stored material. The Division recommends that the storage area(s) be located outside the floodplain. If it is necessary to have storage areas within the floodplain, the applicant must also describe protection measures that will be employed to contain the materials in the event of a flood Applicant's Response: The applicant will prepare and implement a Spill Protection and Counter Measure Control Plan, as provided under State and federal law,that will specify containment and other countermeasures necessary to prevent potential petroleum hydrocarbon spills from reaching navigable waters of the State. That stated, asphaltic cement will not be used by the Applicant at the site. The Applicant proposes to build a ready mix truck washout structure designed to contain all wash water (i.e., to be zero discharge). The on site fuel station will be designed to contain 100% of all stored fuels and lubricants. At the direction of the Weld County Department of Public Works, 5 and since most of the site of the processing plant is within the 100-year flood plain, all fuel storage tanks will be secured to prevent their movement in the event of flooding in the area of the processing plant. Rule 6.4.5 Exhibit F-Reclamation Plan 14. Please specify the anticipated minimum thickness or range of thickness of topsoil replaced for those areas where topsoil will be replaced; in particular, Stages 1 and 2 and the reclaimed pond slopes and surrounding affected areas. Applicant's Response: During reclamation,topsoil will placed over reclaimed areas at a thickness of 6 to 12 inches. This includes Stage 1,the side slopes of Stage 2, all pond slopes and surrounding affected land. 15. The applicant provide a separate seed mixture for the reclaimed area of Phase 2. Please list the seeding rate of Phase 2- Wash Fines Basin Seed mixture in pure live seed per acre (PLS/acre). Applicant's Response: The following seed mix will be used for the reclamation of Stage 2.

Applicant's Response: The total area requiring topsoil replacement and revegetation is estimated to be 45 acres. Rule 6.4.7 Exhibit G- Water Information J7. Much of the site is located in the 100-year flood plain of the South Platte River. Wherever mining will occur within 400 feet of the river channel, a flood analysis and flood control plan must be evaluated and submitted This would include pit side armoring, river site armoring, inflow and outflow channels, or other appropriate measures. In order to mine within 400 feet of the river, the applicant must submit engineering designs and updated maps to address this situation. Applicant's Response: The Applicant proposes a temporary mining only setback from the South Platte River of 100 feet for Stages 1 and 2 and a 400 foot setback for Stages 3, 4 and 5. The proposed 100-foot setback for Stage l is based, in part, on the fact that Stage 1 is protected from flooding by an existing seven(7)foot high flood control berm located between the east side of Stage 1 and the South Platte River. In addition, much of the west bank of the South Platte River, within the Holton Lakes permit boundary, has been bermed and rip-rapped to preserve the current alignment of the river(see photographs below). The protection along this section of the west bank of the South Platte has been in place for more than 30 years and it is the result of a cumulative effort over the past several decades by a number of parties including the Colorado Department of Transportation, Weld County Public Works, and previous property owners. The 100-foot mining setback for Stages 1 and 2 are characterized as"temporary"because, following mining,the Applicant proposes to backfill each such stage to within 2 to 3 feet of pre-mining surface elevations. In Stage 1, backfilling will start on the east side of the pit and move from east to west. In Stage 2, backfilling will begin in the southwest end of the Stage and progress north- northeast over the life of the operation. Two flood overflow structures will be constructed one in the southwest end of Stage 2 and one in the northeast end of Stage 2 to protect it from flood 7 damage. As mentioned above, and as determined in consultation with Division staff,the Applicant has determined that the riverside setback for Stages 3-5 will be 400 feet. Any future reduction of this setback will be accomplished by way of a technical revision based on appropriate river bank stability analysis. sae: .•- Picture 1 Seven foot high Flood Protection Berm Located on the East Side of Stage 1 (right hand side of the picture). 8 ti Picture 2 Riprap along the west bank of the South Platte River 18. According to Exhibit G, it appears that most if not all of the site lies within the 100 year floodplain (and possibly within the 10, 25, &50 year floodplains) of the South Platte River. In the event of a significant flood event (10 year flood or greater) it is likely that the existing pits and/or reclaimed lakes will be captured by the South Platte River. Accordingly, the Division requests that the applicant provide the flood elevations(s) to be expected under a "worst case"flooding scenario and specific mitigation measures that will be implemented to minimize the potential for any offsite impacts. Mitigation measures might include mining dry pit slopes at a maximum of 1:1, installation offlood control spillways within the reclaimed lakes, installation of drainage pipes within the internal berms separating pits and/or armoring reclaimed pit slopes in close proximity to the South Platte River with erosion control riprap. Ifflood mitigation plans are to be prepared, they must specifically address the potential for erosion of the lateral berms between the pits and the gas/oil pipeline both during mining and following reclamation. Applicant's Response: Much of the Holton Lakes site is located within the 100-year floodplain of the South Platte River as mapped by FEMA. That said, the Applicant does not agree with the Division's statement that "In the event of a significant flood event (10 year flood or greater) it is likely that the existing pits and/or reclaimed lakes will be captured by the South Platte River. " It is in the interest of the Applicant, the property owners, Weld County and the Division to ensure that the South Platte River maintains its existing channel through the Holton Lakes property and that off-site flood impacts are minimized to the greatest extent possible. To that end,the Applicant's proposed mining and reclamation plans are intended to protect both the river,the mined and reclaimed areas, and offsite areas. If by referring to a "worst case flooding scenario" in the comment above the Division is referring to a 100-year flood event, we can safely say that the majority of the 9 Holton Lakes site,as well as the river corridor both up-stream and down stream of the site,will be inundated by several feet of water. With such an event and the Division's expressed concern in mind,this is to confirm that the Applicant is required to obtain an approved Floodplain Use Permit(FUP) from Weld County as a condition of Use by Special Review Permit the Applicant is in the process of seeking from the County. To that end, Weld County is authorized by FEMA to administer and regulate all activities in the 100-year floodplain of the South Platte River and its regulated tributaries in Weld County. The purpose of the Weld County FUP process is to insure that off-site flood impacts are minimized regardless of the nature of the activity proposed within the 100-year floodplain. Therefore,the FUP process is the appropriate process in which the Division's concerns will be addressed. Therefore, included with this adequacy response is a copy of the Holton Lakes FUP as submitted to Weld County. Finally, there are no "lateral berms"planned between the pits and gas oil pipelines either during mining or after reclamation, nor will there be any"lateral berms"between any of the ponds following reclamation. 19. Please quantify the velocity and volume of flows expected on site from a 100 year flood event, as well as the elevation of the 100 year base flood event and its relation to the elevation of any proposed spillways and lake shore embankment. Also,please quantify or characterize the expected groundwater surface between the stream channel and the adjacent floodplain under such event. Applicant's Response: As discussed with Division Staff, details related to this item will be addressed in the event the Applicant should choose to seek a technical revision to the permit to reduce the 400-foot _ riverside setback for Stages 3-5. 20. Please quantify the velocity and volume offlow expected as well as magnitude offlood event required to produce a "bankfull"event in the adjacent reach of the South Platte River. Also,please quantify or characterize the expected groundwater surface between the stream channel and the adjacent floodplain under such event. Applicant's Response: As discussed with Division Staff, details related to this item will be addressed in the event the Applicant should choose to seek a technical revision to the permit to reduce the 400-foot riverside setback for Stages 3-5. 21. Rule 6.4.7(1) requires the applicant to directly state if surface water or ground water will be affected by the mining operation. The applicant noted registered wells within 600 feet of the affected land based on information obtained by the OSE. However, a ground water study may reveal wells outside the 600-foot-radius that may be impacted. If so, these will need to be addressed and exhibits amended. In accordance with Rule 6.4.7(2)(b), the Division requests that the applicant identify and characterize the aquifer to be mined in or through. The Division also requests that the applicant define or predict the cone of depression or shadow and mounding effect expected for any areas to be dewatered and dry mined or as a result of installation of the slurry walls. The cone of depression and assessment of other effects should define, at a minimum, the horizontal and vertical extent of 10 expected impacts. If during the assessment, the applicant determines that a drawdown, shadow or mounding effect will occur offsite that may impact a current groundwater user, the applicant must explain any mitigation measures to be implemented and trigger points that would put mitigation measures into effect. Typically, a trigger point of a 2 feet change from historic ground water levels is acceptable. Applicants Response: The proposed operations will not adversely affect surface or ground water. All known(i.e., registered) wells within 750 feet of the permit boundary are shown on the aerial photograph of the pit and adjacent property (See Exhibit C-3, Sheet 3 of 7). Forcing the Applicant to identify unregistered wells is highly problematic, particularly since the legality of such wells, as a threshold matter would be a question for the State Engineer to review.l The nearest domestic well,to an unsealed mining stage (i.e., Stage 1), is approximately 1000 feet west of Stage 1. In addition,there are two (2) irrigation wells that were historically used in the vicinity of Stages 1 and 2;however, it appears that these wells are abandoned. All other known wells in the vicinity of the Holton Lakes site are located opposite mining stages that will be sealed with a slurry wall before they are dewatered. Therefore, while no affect from dewatering will be experienced by those wells,the Applicant proposes to implement a ground water monitoring program once the Division has approved the Holton Lakes 112 Permit. The proposed monitoring program includes the installation of eight(8)monitoring wells around the perimeter of the permit boundary. The Mine Plan Drawing(Exhibit D-Sheet 6 of 7) shows the location of the eight(8)monitoring wells. Static ground water elevations in each well will be measured monthly prior to mining, during mining, and up to two years after reclamation of each stage of mining. In the event that there is a change from ground water levels, as measured pre-mining, of two (2) feet or more, the Applicant will determine if any nearby operating wells have been adversely affected and, if so, take appropriate steps to remediate any such impacts. For Example, if the monitoring program indicates that a nearby domestic well has been impacted,the Applicant will provide an alternative source of potable water for the affected party, or otherwise address the water shortfall (the Applicant may install a ground water recharge pond opposite the affected area and pump ground water from the pit to the recharge pond). If on the other hand, the monitoring program indicates that ground water mounding is occurring on adjacent property, the Applicant will install a permanent cut-off trench to drain excess ground water away from the affected area. 22. The applicant needs to describe how the drawdown of the pits and any shadowing/mounding effects will impact the structural integrity of the surrounding wells, surface water drainages, activities which rely on ground water in the vicinity of the site, and vegetation on or near the site (including the cottonwood trees in the riparian area near the South Platte River and the wetlands adjacent to 1 From a policy standpoint,requiring applicants to identify unregistered wells is akin to asking applicants to identify non-record owners of real property so they can be provided notice of a Section 112 permit application. For the purpose of efficiency and expediency,it is well recognized that there is a system for identifying record owners of property for notice purposes. The same logic applies to the owners of registered wells versus non-registered wells. There is simply no efficient,or even comprehensive method for identifying the latter. 11 the pits). The applicant must also describe any mitigation measures to be implemented and trigger ^ points that would put mitigation measures into effect. Applicant's Response: As previously mentioned,mining Stages 3,4, and 5,which total approximately 83%of the area to be mined,will be sealed with a slurry wall prior to dewatering. Therefore,no groundwater drawdown impacts of any kind to the "structural integrity of the surrounding wells, surface water drainages, activities which rely on ground water in the vicinity of the site, and vegetation on or near the site"will result from these three mining stages. In addition, ground water elevations in the vicinity of all five mining stages are controlled by surface water flows in the South Platte River and Big Dry Creek. Therefore, the existing riparian vegetation between the mining stages,the river, and Big Dry Creek"(including the cottonwood trees in the riparian area near the South Platte River and the wetlands adjacent to the pits). "will not be adversely affected by pit drawdown or by ground water mounding bet-Anse the river and Big Dry will effectively act as cut-off trenches. As mentioned in the response to comment 21 above, in the event that there is a change in the historic ground water elevation of two (2) feet or more from measured pre-mining groundwater elevations,the Applicant will take appropriate steps to mitigate possible adverse impacts associated with the change in the elevations. 23. Based upon the possible potential for ground water impacts from dewatering and lining three of the pits, additional monitoring wells should be considered and installed to ensure compliance with Rule 3.1.6O) of the Construction Material Rules and Regulations which require that "disturbance to the _ prevailing hydrologic balance of the affected land and to the surrounding area and to the quantity and quality of water in surface and ground water systems both during and after the mining operation and during reclamation shall be minimized... " In particular, the Division recommends monitoring wells be selected or installed to monitor impacts that may affect registered and unregistered wells and vegetation on both sides of the river (i.e. wells should be considered in proximity to Stages 2 and 4 to assess impacts) Applicant's Response: The Applicant proposes to implement a ground water monitoring program once the Division has approved the Holton Lakes 112 Permit. The proposed monitoring program includes the installation of eight(8)monitoring wells around the perimeter of the permit boundary. The Mine Plan Drawing (Exhibit D-Sheet 6 of 7) shows the location of the eight monitoring wells. Static ground water elevations in each well will be measured monthly prior to de-watering, during mining and up to two years after reclamation of each stage of mining is completed. In the event that there is a change from measured pre-mining water levels of two (2) feet or more,the Applicant will determine if any nearby operating wells have been adversely affected and, if so, take appropriate steps to remediate any such impacts. For Example, if the monitoring program indicates that a nearby domestic well has been impacted,the Applicant will provide an alternative source of potable water for the affected party, or otherwise address the water shortfall (the Applicant may install a ground water recharge pond opposite the affected area and pump ground water from the pit to the recharge pond). If on the other hand,the monitoring program 12 indicates that ground water mounding is occurring on adjacent property,the Applicant will install a permanent cut-off trench to drain excess ground water away from the affected area. 24. The applicant commits to measuring the ground water elevations in 4 monitoring wells monthly. In the event that the neighboring wells are adversely affected by the pit, the Applicant will promptly take steps to mitigate any adverse impacts. Please commit to collecting and reporting one full year of monthly data prior to the beginning of mining and monthly data during the life of the operation. All monitoring data will need to be submitted to the Division in the Annual Reclamation Report. As previously stated, the applicant must describe any mitigation measures to be implemented and trigger points that would put mitigation measures into effect. Applicant's Response: The Applicant will commit to collecting ground water elevation data, as described in comment 23 above, prior to the start of pit dewatering and include this information in its annual report to the Division. If possible, the Applicant will collect twelve (12) months of data prior to the start of dewatering operations, but it cannot commit to delay the start of dewatering. In the event that there is a change from measured pre-mining water levels of two (2) feet or more the Applicant will determine if any nearby operating wells have been adversely affected and if so take appropriate steps to remediate the impact to them. For Example, if the monitoring program indicates that a nearby domestic well has been impacted the Applicant will provide an alternative source of potable water for the affected party, or otherwise address the water shortfall (the Applicant may install a ground water recharge pond opposite the affected area and pump ground water from the pit to the recharge pond). If on the other hand,the monitoring program indicates that ground water mounding is occurring on adjacent property,the Applicant will install a permanent cut-off trench to drain excess ground water away from the affected area. 25. The applicant states that in order to protect cottonwood frees from adverse impacts due to pit de- watering the applicant will periodically pump ground water from the dewatered pit to areas where frees are at risk of damage from dewatering. Will the applicant pump ground water on other riparian areas? Since cottonwoods could die by the time a 2 foot drop in ground water level occurs, a trigger point of I foot or if the vegetation is showing signs of stress (assessed by a qualified individual), whichever comes first, would be acceptable. Immediate interim mitigation measures must be specified to protect this vegetation. Applicant's Response: The Applicants statement regarding the protection of cottonwood trees from adverse impacts from pit dewatering pertain only to trees within the Holton Lakes permit boundary. The Applicant believes that the only area of concern off-site is adjacent to the southeast corner of Stage 2. If possible, the Applicant will pump ground water from Stage 2, as part of the pit dewatering, into an area adjacent to the trees opposite the southeast boundary of Stage 2. In this way, impacts to the existing hydrologic balance and therefore the trees will be minimized. The Applicant is willing to pump water to protect off-site trees as long as such pumping can be accomplished under the approved 112 Permit. 13 26. Please identify all cottonwood groves in the wildlife corridor and within the boundaries of potential — offsite ground water impacts to help assure adequate monitoring is in place. Applicant's Response: There are two such areas of trees outside the Holton Lakes permit boundary. The first is located opposite the southeast corner of mining Stage 2 and the second is located opposite the southwest corner of mining Stage 3. Ground water monitoring wells numbered 3 and 5 will be installed adjacent to each of these two areas to monitor potential adverse affects of dewatering. That stated,the Applicant does not expect such affects opposite the southwest corner of mining Stage 3, since Stage 3 will be sealed by the installation of a slurry wall. 27. The applicant states that registered alluvial wells within 600 feet were identified based on SEO records. Were field inspections conducted to identify ALL wells within 600 feet? Please revise the exhibits to depict the actual location of the alluvial wells. Will any wells beyond the 600 foot radius be affected by the mining operations? Applicant's Response: Map Exhibit C-3 (Sheet 3 of 7 attached)has been revised to show the requested information. There will be no adverse impacts to any ground water wells outside the Holton Lakes permit boundary.The status of wells in the vicinity of the Holton Lakes Property was discussed with the Holtons; however,no field inspections were conducted to identify ALL wells within 600 feet of the subject property. Field Inspections were not carried out because it is beyond the ability of the Applicant to determine which wells are and are not registered with the SEO, which wells have been abandoned and the condition and capacity of any wells that may or may not be operational. See response to comment 21 above and Footnote 1. 28. Please provide a reclamation plan for the monitoring wells proposed on site. Please include the depth of wells, diameter of the wells and how the wells were completed This will assist the Division in determining a final cost of reclamation. Applicant's Response: All monitoring wells will be constructed of two (2) inch perforated PVC pipe and installed to a depth of 25 feet. Upon completion of all mining and reclamation activities, the wells will be filled with sand and gravel and closed in conformance with the requirements of the State Engineer. 29. Please depict the location on a map where mine water will be discharged If mine water is discharged into a ditch or other man-made structure,please provide consent to discharge water into this structure. If water is discharged into a ditch that is unlined, it may be prone to erosion if the discharge rates exceed the carrying capacity of the ditch. The applicant should submit documentation to the Division for review as to the proposed maximum discharge rate into the ditch and specifications as to how much water the ditch can carry without experiencing erosion. 14 Applicant's Response: All NPDES ground water discharge locations (i.e., point source discharges) are shown on the Mine Plan drawing(Exhibit D) Sheet 6 of 7. 30. Please provide a representative cross sectional diagram for the pits which adequately depicts the features of the alluvial aquifer with the affected and surrounding areas. The cross sectional diagram should be drawn to scale and provide the following information; o Existing reclaimed excavations(s) and high lake water elevation o Groundwater (piezometric)surface o Proposed slurry wall installation o South Platte River (from top of North Bank to top of South Bank) o 100 year Floodplain boundaries (existing&proposed) & elevations o South Platte River-Floodway boundaries o Any existing wells within 600 feet of the pits o Ordinary high water mark of the South Platte River o Invert of the South Platte River o Significant wetlands, and/or woody riparian vegetation Applicant's Response: See the Reclamation Plan drawing(Exhibit F) Sheet 7 of 7. Rule 6.4.8 Exhibit H- Wildlife Information 31. On page 9 of the wildlife report submitted by ERO Resources Corporation it is stated, "the prairie dog burrows within the northwestern portion of the project area are potential habitat for burrowing owls. ERO recommends that any soil disturbance or removal of prairie dogs be conducted between October 31 and March 1. If prairie dog burrows are disturbed during the March 1 to October 31 timeframe, CDOW will recommend formal surveys for burrowing owls just prior to any habitat disturbing activities. " Please incorporate the ERO recommendation into the mining and reclamation plan. Applicant's Response: Agreed. 32. On page 14 of the ERO report it is recommended that Red-tailed hawk nests be removed outside of the breeding season (March 1 to July 31) or take reasonable precautions to ensure that raptors or other birds are not using the nests. Please incorporate the ERO recommendation into the mining and reclamation plan, and specify the reasonable precautions to be taken. 15 Applicant's Response: Agreed. Rule 6.4.14 Exhibit N-Source of Legal Right to Enter 33. The applicant submitted an "Option and Agreement to Purchase Aggregate Materials in Place. " The Division does not believe that an option to purchase the property is sufficient to demonstrate adequate legal right of entry. The language in the option agreement does not secure the legal right to enter and mine/reclaim on the site. In fact, the option allows the applicant a 24-month period to exercise the option to purchase the property to become a purchase and sale agreement. The Division cannot approve an application unless a secure source of the right to enter and mine/reclaim on the proposed land is provided. Applicant's Response: See attached letter from Thomas M. Holton to Erica Crosby. Rule 6.4.19 Exhibit S-Permanent Man-Made Structures 34. The applicant proposes to mine through gas/oil lines in Stage 5. If the applicant intends to mine through and relocate the gas/oil lines they will need to submit a notarized agreement between the operator and the owner(s)/easement holders of the gas lines. Until such agreement is submitted and approved by the Division, the applicant will need to maintain a suitable mining off-set distance from the gas lines. If such notarized agreements cannot be achieved during this review period, then a revision to the permit will need to be filed in the future prior to mining closer than the approved mining off-set distance. Applicant's Response: The applicant and the land owner will relocate, at their shared expense, all gas/oil lines in Stage 5 prior to the start of slurry wall construction in that stage. In the event that the Applicant and the owner(s) of the gas/oil lines have not reached an agreement regarding the relocation of said lines prior to the start of slurry wall construction, the Applicant commits to a 100 foot mining setback as recommended by Scott Cox. 35. The Scott Cox report recommends maintaining a 3h:1 v distance from all permanent man made structures (based on the depth of the pit at 33 feet). However, Exhibit D depicts off set distances less than what was recommended by the Scott Cox report. In particular, Excel power poles- 50', east of Sage 2- 50', Hwy 85- 50', United power lines/poles- 25'and an unknown distance from structures south of Stage 3. Please depict all of the off set distances from various structures on the mine plan exhibit as recommended by the Scott Cox report or submit a notarized agreement in accordance with Rule 6.4.19. 16 Applicant's Response: Setbacks from the Xcel power poles and Colorado Highway 85 are 100 feet as recommended in the Scott Cox Letter Report and depicted on the Mine Plan drawing(Exhibit D). The United Power Poles will likely be removed entirely prior to the start of mining in Stage 3. In the event that the poles are not removed prior to the start of mining,the Applicant has committed to replace and or repair any poles damaged because of their mining activities (see attached draft agreement). Enclosed, please find a letter of objection regarding the application from Kerr-McGee Oil & Gas Onshore LP. Please respond to the concerns noted in the letter. Because an objection has been filed, the decision date will automatically be extended on or before the 120`x'day to coincide with the June 13, 2007 MLRB hearing. However, the Division must make a recommendation to approve or deny the application to the MLRB on May 16, 2007. Applicant's Response: The Applicant has met, and is continuing to meet with a representative of Kerr-McGee as part of an on going process to negotiate a Surface Use Agreement(SUA) acceptable to all parties; however,the terms and conditions of the SUA have yet to be fully established and memorialized. Like Kerr-McGee, the Applicant prefers to attempt to conclude a mutually acceptable SUA. That said, the Applicant does not believe that the Division has the authority to withhold final approval of the Holton Lakes Permit until the all parties have concluded a SUA, as requested by Kerr McGee in their letter of objection dated March 29, 2007. The Division's authority is limited to ensuring that Kerr McGee's existing improvements (i.e., significant man-made structures)will not be adversely affected. 17 ADEQUACY RESPONSE ATTACHEMENTS PERMIT NO. 2007-008 HOLTON LAKES • CERTIFIED MAIL RETURN RECEIPTS • LETTER FROM THOMAS M.

The Applicant, Ready Mixed Concrete Company has applied to Weld County for a Use by Special Review Permit (USR 1608) to mine sand and gravel on the Holton property located near the Town of Fort Lupton, in unincorporated Weld County, Colorado. The operation will be known as the Holton Lakes Pit. The subject property is located in the Sections 6 and 7, Township 1 North, Range 69 West of the Sixth Principal Meridian, Weld County, State of Colorado. The permit area is approximately 298 acres in size, and is located south of Colorado State Highway 52 and west of Colorado state Highway 85. The South Platte River flows from south to north through the property, passing under a bridge for Highway 52 at the north end of the site. The Holton property is proposed to be mined in 5 stages. In order to minimize surface disturbance, mining and reclamation will be conducted concurrently to the greatest extant practicable. The operator will concurrently reclaim pit areas in locations where mining has been completed. Reclamation, including regrading and seeding will be completed in 2 to 3 years following the completions of mining operations in Stages 3, 4 and 5. Stages 1 and 2 will be backfilled to approximate per-mining grades over the 8 to 10 year life of the mine. Dry mining techniques will be used. Initially, a dewatering ditch will be excavated around the perimeter of each mining stage. Groundwater recovered in the dewatering ditch will be discharged in accordance with Colorado/NPDES discharge permit regulations. Prior to dewatering of mining stages 3, 4 and 5, a soil-bentonite slurry wall will be installed around the perimeter of each mining stage. The site will be mined using scrappers and front-end loaders. Excavated sand and gravel will be discharged to a field conveyor system for transport to the on-site processing plant located in the north half of Stage 5. Additional conveyors may be used inside the mine areas to facilitate transport of the resource. Topsoil and overburden will be placed in temporary stockpiles within the mining area limits. Primary access to the Holton Lakes operation will be via an existing farm road access from Colorado State Highway 52. The Highway 52 access will be upgraded per CDOT approved specifications and design. The proposed operation consists of no permanent structures to remain after mining and reclamation of the site. During operation of the pit site, the only habitable facility will be a modular scale house and office, which will be adequately anchored and which r will be built with its lowest floor above the base flood elevation. The scale house and office, along with a portable sand and gravel processing plant, a portable concrete batch plant, fueling station, material stockpiles, and employee parking, will all be Holton Lakes Sand and Gravel Pit 2 located in the Stage 5 mining area in the northeastern corner of the site. Section 2 - Existing Floodplain The 100-year base floodplain (Zone A5) and the subject property are shown on the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map Panel # 080266-0981 C, dated September 28th, 1982, and also on the FEMA Flood Boundary and Floodway Map Panel#080266-0012, dated September 28, 1990. For this reach of the South Platte River, a detailed study has been performed, and therefore water surface elevations have been determined and shown for the 1%, or 100-year return period flood event. Please note that the vertical datum that the FEMA maps are based on is referenced to the National Geodetic Vertical Datum of 1929 (NGVD 29), while the site mapping and topography are based on the North American Vertical Datum of 1988 (NAVD 88). For this local, 2.92 fret needs to be added to the NGVD 29 elevation in order to convert to an equivalent NAVD 88 elevation (in other words, a flood elevation of 4998 shown co--- the FEMA flood panels equals an elevation of 5000.92 on the site plan maps). Ft clarity, the 100-year flood elevations shown on the Flood Hazard Development Permit map have been converted to the NAVD 88 datum. The FEMA floodplain mapping shows that the entire Holton property is located within the 100-year floodplain of the South Platte. FEMA map #080266-0012 shows the limit of the 100-year regulatory floodway. As noted on the map, boundaries of the floodway have been computed at cross-sections and interpolated between cross sections. Inspection of the map shows that the western floodway boundary location at cross-section "AK" is almost 800 feet further west than the boundary at cross-section "AJ", however the two cross-sections are only 150 feet apart. In addition, the overall floodplain width and boundaries are almost identical at the two cross-sections. It also appears that the western floodway boundary that has been interpolated between cross-section "AL" and cross-section "AK" has been drawn as a straight line between the two, rather than having a curvilinear alignment that would be expected to correspond with the eastern floodway boundary (that curves eastward to account for main river channel alignment). Based on this review, we would recommend a reconsideration of the western floodway boundary between cross-sections "AL" and "AK" as shown on Figure 3 of this report. This revised estimated floodway boundary results in a small portion of the Holton property in the northwest corner of the site being removed from the floodway zone. Holton Lakes Sand and Gravel Pit 3 Section 3 - Floodplain Impacts The proposed Holton Lakes Pit sand and gravel mining operation and post mining reclamation plan are not expected to create any adverse floodplain impacts. In no case will the proposed pith and reclamation create any rise in flood water surface elevations. Previously constructed riverbank protection and flood control levees will be left in place. Where appropriate, spillways will be provided between the pits and between pits and the river main channel in order to prevent buildup of large differential head. This reduces potential head cutting and helps to prevent post-flood realignment of the main river channel. For lesser and more frequent flood events (smaller than the 100-year flood), the mined pit areas will provide a small amount of beneficial storage of flood water with subsequent (and again small) reduction in downstream flood profiles. Section 4- Weld County Zoning Ordinance Re- quirements Per the supplemental requirements of the Weld County Flood Hazard Development Permit Procedural Guide, the following is an explanation of how Section 23-2-480 of the Weld County Code has been or will be met. 1) 23-5-250. FW(Floodway) District The proposed sand and gravel mining operation and subsequent site reclama- tion will not result in any permanent development within the Floodway Dis- trict zone. No habitable structures are proposed to be located in the floodway (the only proposed habitable structure will be a scale house that will be located outside of the estimated floodway as previously described). All uses and equipment within the floodway zone will be such that they can be removed from the zone prior to flooding (vehicles, excavation equipment, etc.) or will be adequately anchored or protected to prevent becoming debris, potential projec- tiles, or erosion during a flood event (processing plant, concrete batch plant, conveyor systems, material stockpiles, etc.). No development is proposed that would create any rise in estimated water surface elevations during the Intermediate Regional (100-year) Flood. In addition, the proposed use will not limit or restrict the flow capacity of the floodway. 23-5-260. Uses Permitted in the FP-1 and FP-2 Districts Sand and Gravel mining is a permitted Use by Special Review in the underly- ing Agricultural zoning district. Holton Lakes Sand and Gravel Pit 4 2) The only habitable structure proposed will be a temporary scale house that will be located outside of the floodway zone and built so that the lowest floor is at or above the regulatory flood datum. An elevation certificate will be completed for the proposed structure at the time of building permit issuance. 3) No structures are being proposed that would be required to be watertight below the regulatory flood datum, and hence no certification of design capability to resist hydrostatic and hydrodynamic forces is required. 4) No new or replacement domestic water wells or water supply, treatment, or storage systems are proposed. 5) Only temporary sanitary sewer facilities are proposed for use at the site. Portable San-o-Lets will be used in operational pit areas, and as such, they can be removed prior to a flood event to prevent discharge into flood waters. A buried sanitary sewer vault system will be provided for the scale house/office facility, and will be sealed to prevent infiltration of floodwater or discharge from the system into floodwaters. 6) No encroachments, including fill, new construction, substantial improvements, and other developments are proposed that would result in any increase in flood levels during the occurrence of the intermediate regional flood. '7) No use is being proposed that would limit or restrict the flow capacity of the floodway. 8) No fill material, with the exception of temporary material stockpiles will be used in the FP-1 or FP-2 (Floodprone) Districts. All temporary stockpiles will be placed and orientated so as not to be exposed to erosional forces associated with the intermediate regional flood. Section 5- Alteration or Relocation of Water Course No uses are being proposed that would be expected to result in alteration or relocation of the South Platte River water course. No mining or operations will take place within the existing river main channel alignment, and existing river bank protection (armoring) and river alignment levees will be left in place. Appropriate measures, including side channel spillways, setbacks from the main river channel, and separation between mining stages and proposed reclaimed pit areas are proposed in order to discourage "capture" and realignment of the main river channel during the intermediate flood event. Holton Lakes Sand and Gravel Pit 5 Section 6- Summary and Conclusions • The proposed Holton Lakes Sand and Gravel Pit mining and reclamation will be in conformance with all applicable standards specified in Section 23-2-480 of the Weld County Code. • The proposed mining and reclamation plan has been designed to minimize adverse floodplain impacts to the greatest extent practical. • The proposed mining and reclamation plan will not cause any changes on downstream or upstream flooding conditions. • The proposed mining and reclamation plan will not create any measurable rise in estimated flood profile or water surface elevations of the intermediate regional (100-year) flood. • No permanent structures are proposed to be located within the FP-1 or FP-2 (Floodprone) District. Holton Lakes Sand and Gravel Pit 6 Section 7- Certification As required by the Supplemental Requirements for a Flood Hazard Development Permit and Section 23-2-490 of the Weld County Code, I certify that the following standards have been met: 1. All new or replacement domestic water wells or water supply, treatment, or storage systems are designed to prevent inundation or infiltration of floodwa- ter into such system by an intermediate regional flood (an elevated bottled water supply will be provided within the proposed modular scale house struc- ture) 2. All new or replacement sanitary sewer treatment systems, including individual sewage disposal systems, are designed to prevent inundation or infiltration of floodwater into such system and to prevent discharges from such systems into the floodwaters of an intermediate regional flood. 3. No encroachments, including fill, new construction, substantial improvements, and other development are proposed that would result in any increase in floc— levels during the occurrence of an intermediate regional flood. 4. The proposed use will not limit or restrict the flow capacity of the floodway. 5. Fill material is designed to withstand the erosional forces associated with an intermediate regional flood.
