Recent hydrologic monitoring data were checked for compliance with the <br />monitoring requirements in Exhibit 14, Table A of the permit application. <br />All monitoring requirements appear to have been met. <br />The pipeline has been laid for pumping mine water from the Fish Creek <br />borehole to the 7 North Escape Shaft. This work was approved in MR-179. <br />The pipeline trench has been backfilled. Seed will need to be spread in <br />the spring. A work crew was installing the pumphouse at the borehole <br />site. <br />The discharge from the treatment ponds at the Fish Creek borehole <br />(outfall 001 of NPDES permit C0042161) appeared to be less than 100 gpm of <br />clear water. To check the impact of this discharge on Trout Creek, I <br />measured field electroconductivity (EC) values at three locations in the <br />creek. The measurements were made from county road bridges during a two- <br />hour period. As shown on the following map, the EC value downstream from <br />the mine was 560 mmhos/cm, significantly below the material damage <br />suspect level of 1,000 mmhos/cm. <br />Brian Watterson of Twentymile Coal <br />there was not a sulfate exceedance <br />Foidel Creek Mine last month. High <br />suggested a possible exceedance. A <br />indicated the sulfate concentration <br />limitation. <br />explained that lab results indicated <br />in Trout Creek downstream from the <br />field conductivity values had <br />sample was taken, and lab analysis <br />was below the 250 mg/1 instream <br />Processing Waste <br />There was no activity on the refuse pile. No problems were found on the <br />pile. <br />Support Facilities <br />No problems were found in the following areas: yard area, explosives <br />magazine, belt-outback, million gallon tank, and hazardous materials <br />storage area. <br />Subsidence <br />No structures or renewable resource lands were undermined in the last <br />month. <br />4 <br />
