West Farm Pit, Permit No. M-2008-078, Technical Revision No 5(TR-05),Adequacy Review No. 1 Response <br /> August 5,2019 <br /> -3- <br /> Reclamation under the conveyor will consist removing the ties and concrete pads, placing topsoil, and <br /> seeding of the disturbed areas. Note that the topsoiling and reseeding of these areas is already <br /> included in the permit. As noted previously, approximately 350 wood ties will be removed and landfilled. <br /> The concrete pads, including the washer screen pads, head unit pad, and radial stacker pads, will be <br /> broken up and either used for riprap or landfilled. The total volume of concrete to be broken up and <br /> removed is: <br /> Washer Screen Pads (2 pads x 12 ft x 19 ft x 1 ft thick): 17 cubic yards <br /> Head Unit Pad (1 pad x 16 ft x 35 ft x 8 in thick): 14 cubic yards <br /> Radial Stacker Pads (2 pads x 5 x 4 ft x 4 ft x 2 ft thick): 6 cubic yards <br /> Total: 37 cubic yards <br /> Because all concrete pads will rest on the existing ground surface no backfill will be required after <br /> removal of the pads. <br /> The culvert and pit run materials placed on CR HH.5 and over the culvert will be removed and the road <br /> restored to its original grade. 100 lineal feet of culvert and approximately 9,125 cubic yards of pit run <br /> will be removed to restore the road to its original grade. <br /> 5) Please specify any permits, licenses, or approvals that will be required for the installation, operation, or <br /> reclamation of the proposed conveyor system. Has the county been notified of the proposed project <br /> involving the county road? <br /> The County is aware of the proposed culvert installation project. PAO has an existing agreement with <br /> the County to maintain CR HH.5 in the vicinity of the pit during the mining activities. PAO is in the <br /> process of amending their existing Special Use Permit with Prowers County to include the conveyor <br /> system and install the culvert across CR HH.5. <br /> 6) Please provide sufficient details in the reclamation bond estimate for the Division to calculate the <br /> required bond, including number of concrete conveyor support pads to be removed, dimensions of the <br /> culvert to be removed, disposal costs for demolished materials (if necessary), and estimated volume of <br /> backfill material. <br /> The type and quantities of materials to be removed are listed above in the response to comment 4. A <br /> revised Exhibit L Reclamation Cost Summary Table and revised financial warranty requirement <br /> calculations are attached with unit costs for each reclamation quantity. <br /> 7) Please provide a revised reclamation plan map including the proposed conveyor system reclamation. <br /> The final reclamation plan for the pit does not change due to the addition of a conveyor system. A <br /> revised Exhibit L Reclamation Phasing Map is attached which shows the conveyor system. <br /> Sincerely, <br /> Todd Yee <br /> J&T Consulting, Ine. <br /> RW, 305 Denver Avenue,Suite D•Fort Lupton,CO 80621 •Ph: 303-857-6222•Fax: 303-857-6224 <br />
