Wolf Creek seam. If this occurs the hole will be cemented from the Wolf Creek seam back to the bottom of the _ Wadge. After completion of drilling a 2" well will be conswcted in the boring. The construction will be the same • as described above. A completion diagram will be forwarded to the MLRD upon the conclusion of the construction of the well. The pad for the monitoring well will be of the same construction as used for the development drill holes. However, a portion of the pad will be constructed on the road thus minimizing the amount of disturbance associated with installing this well. Monitor Well 95M001 Access to the drill site will be on an existing ranch road. The drill site will be adjacent to the road. The drill pad was approximately 50' x 100'. Topsoil was stripped from the pad area and stockpiled adjacent to the pad. After topsoil was salvaged from the site, the site was leveled as necessary and mud pits were dug within the boundary of the site. The material excavated from the pits was placed adjacent to the pit within the boundary of the site. After drilling ceases the pits, once suitably dry, was backfilled with material excavated from them. A trash pit was dug on the site, or an existing mud pit was used to collect trash, such as paper, cans, cardboard, etc. No oily wastes were placed in the pit. The trash pit was backfilled when it is no longer needed. The drill hole was approximately 1500 feet in depth and has a nominal diameter of 8 inches. The hole was drilled with either air, water, foam, mist or any combination of the various circulation media. Any water arising from the drilling containing cuttings passed through the mud pits before being discharged from the site. A secondary sediment containment system of hay bales or silt fence was used to treat any discharge from the site during drilling. The hole was completed with 2 inch steel casing. An inflatable packer was placed above the Trout Creek • sandstone and the hole was grouted to the surface. (h) A description of steps to be taken to oomph kith the requirements of the Clean Air Act (42 U.S.C. Sec. 7=101 et seq.). the Clean Water Act (33 U.S.C. Sec. 122 c[ seii.). and other auplicahlc air and water qualih- laws and re~,ulations and health and sateh standards, or a conv of an apnrovcd nermit or auplication for a nermit. RESPONSE TCC will continue to operate in accordance with air quality emission permits issued by CDOH-APCD. Fugitive dust control measures are employed as an integral part ofthe mining and reclamation operations. Compliance with the air quality permits serves to effect compliance with the Federal Clean Air Act and the Colorado Air Quality Control Ac[. Air pollution control measures are discussed in greater detail under Rule 2.05.6(1), and a copy of the Air Quality Emission Permits issued for the Foidel Creek Mine are presented in Exhibit 29, Emission Permits. TCC will indirectly abide by the requirements of National Pollutant Discharge Elimination System (NPDES) Permit CO-0027154 issued by CDOH-WQCD. CYCC is presently responsible for meeting the effluent limitation standards mandated by this NPDES permit. CYCC will maintain responsibility for the permit until effluent control of the surface drainage entering the shared sedimentation ponds from their property is no longer required. At that time, the permit will be transferred to TCC, if necessary. Twentymile Coal Company is directly responsible for NPDES Permits No. CO-0036684 and CO-0042161. Permit No. CO-0036684 establishes the effluent limitations for the Fish Creek Tipple. Permit No. CO-0042161 governs flow at the Fish Creek Dewatering Facility. The dewatering facility permit, issued in July of 1989, establishes effluent limitations for mine discharge only; surface flow does not enter the impoundment structure.
