§2.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND ACTIVITIES - <br />MZNIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS. <br />2.05.6 Mitigation of Surface Coal Mining Operation impacts. (cont'd.) <br />(3) (b) (ii) (A & B) (Cont'd.) <br />(7) Methane monitoring holes will be drilled over the mine <br />workings. Run-off from the drill pads for monitoring holes <br />does not go through a treatment facility such as a sediment <br />pond. Run-off from the pads will be filtered through a <br />sediment fence. Design of sediment fences for three drill pad <br />configurations are presented in Volume 8, Drainage Design and <br />Location beginning on page SAE-31. The three typical drill <br />pads are designed on a 3H:1V slope, SH:1V slope and lOH:1V <br />slope. The typical sediment fence configuration, berms and <br />ditches for the various slopes and pad sizes are shown on Maps <br />8-8. <br />Methane monitoring hole BRL1-GMW-O1 (Map 9-1) will be <br />constructed where the ground surface is on an approximate <br />lOH:1V slope. The completion diagram for BRLl-GMW-O1 is shown <br />on page SAE-59. <br />(3) (b) (iii) <br /> The entire operations of the Bowie No. 1 Mine and the Bowie <br /> No. 1 West Mine are designed to protect surface and <br /> groundwater from adverse effects. Both are monitored on the <br /> disturbed site, as well as on the permit and adjacent areas. <br /> As discussed in Sections 2.05.6(3)(a)(iii), stipulations <br /> attached to the Operator's FCL C-37210 require that existing <br /> on-tract and cross-tract flows be protected from the effects <br /> of subsidence by limiting coal ex-traction in buffer zones <br /> established by the BLM under Steven's Gulch and East Roatcap <br /> Creek, by formulating a water replacement plan for the repair <br /> of conveyance of storage systems and the replacement of any <br /> water lost from an adjudicated water right, and by maintaining <br /> flows for future use. This plan of collection, recording, and <br /> reporting of ground and surface water quality and quantity <br /> data is discussed as follows: <br /> <br /> <br />/~1R-10$ Revised 09/29/95 <br /> Revised 9/21/01 <br />f~ppROVe~ 113c <br />G /~-9/o N <br />
