The agreement and form of collateral shall be reviewed by County Staff and accepted by the Board of County Commissioners prior to recording the USR plat. (Departments of Public Works and Planning Services) Neither an Improvements Agreement nor collateral is necessary for this project as the Division of Reclamation and Mine Safety(DRMS)requires Hall-Irwin to post a financial warranty with them to guarantee the site is reclaimed according to the reclamation plan. Please refer to the attached bond calculations and warranty letter from the DRMS(9). Per the Mining Plan that was approved by the Weld County Commissioners, there are no proposed screening berms. Hall-Irwin will strip and separately stockpile topsoil and overburden along the perimeter of the active mining phase. If these stockpiles are in place for longer than six months, they will be seeded with a dryland grass mix. While these stockpiles may provide screening for adjacent roadways and properties, they are not intended to be permanent berms. Please note that the exact configuration and size of the stockpiles will change during the course of mining operations as this material will be used to back fill Phases 1 and 2 as well as reclaim the reservoir slope for Phase 3. T. The plat shall be amended to delineate items 1 —11. Please see below how each item was either incorporated or addressed on the USR plat. The USR final plats are attached for your review and approval(3). 1. All sheets of the plat shall be labeled USR-1611. (Department of Planning Services) Completed 2.

EXHIBIT D-MINING PLAN This information provided in this Exhibit is intended to satisfy the requirements outlined in Section 6.4.4 of the Colorado Mined Land Reclamation Board Construction Material Rules and Regulations: (a) Description of the method(s)of mining to be employed in each stage of the operation as related to any surface disturbance on affected lands; The proposed permit area includes a significant deposit of sand and gravel located in the alluvium of the South Platte River in Weld County. The site is located on the east side of Weld County Road 23.5 just north of the intersection of Weld County Road 2 (Baseline Road/1681h Ave). It encompasses two parcels totaling approximately 52.3 acres. The existing Baseline Resource(M-97-058)site,operated by Hall-Irwin Corporation,is directly adjacent to the proposed operation. The existing residence on the Parker property,which is outside of the affected land boundary,will remain during and after mining. This is denoted on the attached Mining Plan Map,please refer to Exhibit C of this application. The permit area will be mined in three phases:Phase 1 and 2 are on the Parker property and Phase 3 is on the former Dersham property(please refer to the attached Mining Plan Map in Exhibit C). Aggregate material mined under this permit will be processed at the existing Baseline Resource operation(M-97-058). This site is located within the 100-year floodplain of the South Platte River. Prior to operating with the 100-year floodplain,the operator will obtain a Flood Hazard Development Permit through Weld County. Site Preparation: Initial disturbance of the property will include: clearing the site of existing structures (with exception of the structures to remain)and establishing the landscape sales yard. Scrapers will strip the topsoil and overburden material and stockpile them separately for use during site reclamation. Any excess material not needed for reclamation may be sold or hauled off-site during the life of the mine. Initial disturbance of Phase 3 will include installation of a slurry wall around the mining area prior to exposure of groundwater in this Phase. Dewatering trenches will be excavated down to bedrock to control groundwater in the active mining phase. Once water levels are controlled through the dewatering system,the sand and gravel i. material will be excavated down to bedrock using heavy equipment. Groundwater collected in the dewatering trench will be discharged into the existing mine dewatering system of the Baseline Resource site located directly adjacent to this permit area. Currently the adjacent Baseline Resource site has a Stormwater Management Plan and Spill, Prevention,Control and Countermeasures Plan. If deemed necessary by the State of Colorado Department of Public Health and Environment and the Federal Environmental Protection Agency,the existing Baseline Resource Plans will be Hall-Irwin Corporation-ParkerlDersham Sand and Gravel Resource—MLRB 112 Permit Application Exhibit D-1 modified to include the Parker/Dersham site. As committed in the"Permit Condition" on page 6 of the Application Form,the applicant will notify the Division of Minerals and Geology in the event of a reportable spill. Mining: The mining on this site will progress in three phases: ■ Phase 1: The Phase 1 mining area, located on the Parker property, is approximately 7 acres. This phase will be dewatered and dry-mined using scrapers,bulldozers,front-end loaders,excavators,or similar type equipment. Material excavated in this mine area will be transported by conveyor belt • system or haul truck to the processing area located at the adjacent Baseline Resource processing plant. Mining will be from west to east in Phase 1. ■ Phase 2: The Phase 2 mining area, also located on the Parker property,is approximately 10 acres. This phase will also be dewatered and dry-mined using scrapers, bull-dozers,front-end loaders,excavators,or similar type equipment. Material excavated in this mine area will be transported by conveyor belt system or haul truck to the processing area located at the existing adjacent Baseline Resource processing plant. Mining will be from west to east in Phase 2. ■ Phase 3: The Phase 3 mining area,located on the former Dersham property, is approximately 16.5 acres. A slurry wall will be constructed around this mining area prior to exposing groundwater in this phase.This phase will be dewatered and dry-mined using scrapers, bulldozers,front-end loaders, excavators,or similar equipment. Material excavated in this mine area will be transported by conveyor or haul truck to the Baseline Resource processing area. Mining will be from southwest to northeast in Phase 3. Processing: All material mined under this proposed application will be transported by conveyor or haul truck to the existing processing plant located at the Baseline Resource site currently operating under MLRB permit#M-97-058. Imported Material: Hall-Irwin may import material from other sites to the Parker-Dersham site. The applicant is aware that in accordance with Rule 3.1.5(9)of the Construction Material Rules and Regulations,if any offsite material is used as backfill, a notarized letter will be submitted to the Division indicating the materials are inert. The applicant will supply such a letter to the Division if,at the time of Reclamation,the applicant intends to use j• off-site material as backfill. Hall-Irwin Corporation-Parker/Dersham Sand and Gravel Resource-MLRB 112 Permit Application Exhibit D-2 (b) Earthmoving; Topsoil and overburden will be stripped with scrapers or bulldozers and stockpiled in segregated piles at the top edge of the active mine phase. Excavators,front-end loaders, and bulldozers will be used to mine and stockpile the saleable material on the mine floor. Conveyor belts or haul trucks will be utilized to transport the raw material from the active mine phase to southeast or east to the existing processing area located at the Baseline Resource site. Phases 1 and 2(Parker Property)will be mined vertical and Phase 3(former Dersham Property)will be mined at a 3H:1 V slope. (c) All water diversions and impoundments;and Dewatering trenches surrounding the inside of the mine limit(pit)will control water levels inside the active mine area of all Phases. Dewatering pumps will discharge water from the dewatering trench to the Baseline Resource mine dewatering system, located directly adjacent to the Parker/Dersham permit area. A slurry wall will be installed around the Phase 3 area prior to mining: (d) The size of area(s)to be worked at any one time. The maximum area to be worked on at any one time is approximately 17 acres. (e) An approximate timetable to describe the mining operation. The timetable is for the purpose of establishing the relationship between mining and reclamation during the different phases of a mining operation. The Operator anticipates extracting approximately 800,000 tons of aggregate per year, however,production rate may vary based on market demands: Mining on the Parker/Dersham site will begin upon receipt of all necessary permits for the site: Timetable for Mining and Reclamation Phase 1 &2: Mining will begin In Phase 1 and continue directly into Phase 2. Reclamation for Phase 1 and 2 will begin immediately after mining is complete and will be completed in less than 5 years pursuant to the operator's agreement with the landowner. When possible,concurrent reclamation practices will be used to minimize site disturbance. As excavation progresses in each phase,the operator will place backfill into the previously mined area: Concurrent reclamation will provide the most efficient use of material placement by limiting material handling to the greatest extent possible. ■ Phase 3: Mining will likely begin in Phase 3 within 4 years of the end of mining Phases 1 and 2,depending on market conditions. Phase 3 will be mined in approximately 3 years and reclaimed in 2 years. Hall-Irwin Corporation-ParkerlDersham Sand and Gravel Resource-MI:RB 112 Permit Application Exhibit D-3 Please refer to the Mining Plan Map in Exhibit C for phase areas to be mined, locations and areas. (f) Use Mining Plan Map in conjunction with narrative to present: (i.) Nature, depth and thickness of the deposit and thickness and type of overburden to be removed The operator has drilled soils test borings around the mining area, and has operated the adjacent Baseline Resource site for several years. The locations of the soils borings are shown on the attached Mining Plan Map in Exhibit C. Please refer to the soils information included in Exhibit I of this application. Topsoil&Overburden: Based on soils boring information,the topsoil is approximately 6 inches in depth and will be stockpiled separately from overburden and other spoil. The overburden is estimated to range in depth and will also be stockpiled separately. Please refer to Exhibit I for borings information by Tetra Tech RMC that describes the topsoil and overburden type. Sand and Gravel: Based on soils boring information,the sand and gravel resource is an alluvial deposit that ranges in thickness from approximately 20 to 40 feet,averaging • approximately 30 feet. Refer to the attached boring information in Exhibit I for further details. (IL) Nature of the stratum immediately beneath the material to be mined in sedimentary deposits The stratum immediately beneath the sand and gravel deposit is claystone with lenses of siltsone and sandstone bedrock of the Denver and Arapahoe Formations. (g) Identify the primary and secondary commodities to be mined/extracted and describe the intended use. The primary commodities are sand,gravel and fill;intended for construction materials. (h) Name and describe the intended use of all expected incidental products to be mined/extracted by the proposed operation. There are no expected incidental products to be mined. (i) Specify if explosives will be used in conjunction with the mining(or reclamation) No explosive material will be used on-site.

As required by the Weld County Department of Public Health and Environment, this Plan identifies the techniques Hall-Irwin will use to minimize fugitive dust emissions from this site. 1. During extraction of topsoil and overburden water trucks shall be used as necessary to minimize fugitive particulate emissions. 2. Topsoil stockpile(s)shall be watered as needed and revegetated in spring or fall to minimize fugitive particulate emissions. 3. Overburden stockpile(s)shall be watered as needed and revegetated in spring or fall to minimize fugitive particulate emissions. 4, During loading in and out of raw material and finished product stockpiles,water trucks shall be used as necessary to minimize fugitive particulate emissions. 5. Raw material and finished product stockpile(s)shall be watered as necessary to minimize fugitive particulate emissions. 6. Crushers and screen decks located at this site shall be operated with water spray bars except when there is sufficient moisture in the materials to minimize fugitive particulate emissions. 7. All on-site unpaved roads shall be treated with water as needed to minimize fugitive particulate emissions. Dust abatement on the unpaved roads shall be the primary concern due to the fact that the gravel material will carry moisture with it. 8. Disturbed areas shall be restricted to those areas necessary for the function of the mine. 9. Disturbed areas shall be watered as needed to minimize fugitive particulate emissions. 10. Any disturbed area which becomes inactive for more than one year shall be revegetated during the spring or fall planting time to minimize fugitive particulate emissions. 11. Haul roads are dust controlled with water and magnesium chloride as necessary to minimize fugitive particulate emissions. 12. 15 MPH speed limit signs shall be posted throughout the pit area to minimize fugitive particulate emissions. Page 1 of 1 Waste Handling Plan Hall-Irwin Corporation Purpose This waste handling plan is prepared for the Parker-Dersham Sand and Gravel Resource mining operation in Weld County. As required by the Weld County Department of Public Health and Environment, this Plan identifies the types and estimated volumes of wastes expected to be generated a this site;the types and estimated volume of chemicals to be stored at this site; and the planned methods of waste disposal. Chemical Storage Through Phase 1 and 2 of the mining operations at the Parker-Dersham, there will not be any on-site processing. The processing,sales and recycling operations will be conducted at the adjacent Baseline Resource processing area. As mining operations are completed at the adjacent Baseline Resource site,the processing area may be moved over to the Parker-Dersham Resource site. Generally the sand and gravel mining, processing,sales and recycling operations do not require storage of chemicals other than those required for general vehicle and equipment operation. The total volume and product list may vary slightly when the facility is in full operation. A list of the possible products and approximate volumes maintained on- site are identified below: Material Speculative Volume Diesel Fuel 20,000—24,000 gallons Hydraulic Oil 250—500 gallons Antifreeze 110-220 gallons Waste Oil 500 gallons Waste Antifreeze 500 gallons Misc. Material 550 gallons combined Cleaning Solvents Engine Oil Grease and Lubricants Hydraulic Oil Material Safety Data Sheets(MSDS)will be maintained at the site. Chemical products will be stored in containers approved for the material stored. Adequate containment will be provided for tanks containing material that require spill containment measures. Waste Generation Office waste and other acceptable wastes will be disposed of through contract with a local trash hauler. Any waste oil,waste antifreeze or other chemical waste generated at the site,will be collected by a licensed waste hauler,such as Safety Kleen,or by a Hall-Irwin transport vehicle licensed to carry those materials. The materials will be transported to an appropriate licensed hazardous or special waste collection facility. Any facility personnel handling special or hazardous waste materials will be trained in management and spill prevention. Disposal Facilities Wastes will be disposed of through contract with a local trash hauler will be transported to the disposal facility used by that hauler. There are several waste collection facilities within the general vicinity: Tower Landfill, Inc, Front Range Landfill 8480 Tower Road 1830 WCR 5 Commerce City,CO 80022 Erie, CO 80516 (303)371.5115 (303)828-9400 Any hazardous waste or wastes requiring special handling and disposal will be transported to an appropriate licensed facility.
