• An MSHA waiver was received to stop the use of Wendon Dustrol -10 <br />surfactant in the water spray at the longwall face. The surfactant has been <br />found to be lethal to fish life at 500 ppm. <br />The WQCD also sent an effluent sample and prior toxicity reports to the EPA laboratory in <br />Duluth, Minnesota to investigate the cause of toxicity. WQCD never heard from EPA in <br />this regard. WQCD does not think it is now necessary since the mine has been passing <br />the WET testing during the three (1994 -97) water years. Besides no mine water is <br />discharged at this time requiring WET testing. A copy of the letter dated January 30, <br />1997 from WQCD is attached in Appendix H of the Thirteenth Annual Hydrology Report. <br />On December 28, 1992, WQCD wrote to WFU (now BME) asking either (i) to develop a <br />control program which eliminates the toxicity through treatment of the TDS or (ii) to <br />perform a study which determines if TDS is having a toxic effect on the stream and to <br />develop a level of TDS at the discharge point at which an instream impact is not <br />expected. On March 29, 1993, BME submitted a plan to use the Rapid Bioassessment <br />Protocol III per EPA guidelines. Under this plan, BME would test the extent of <br />impairment, if any, on the aquatic life in the White River due to the mine water discharge. <br />It would involve sampling and testing of micro - invertebrates. No fish would be collected <br />since the U.S. Fish and Wildlife refused to grant permission to do so because of the <br />endangered squawfish being planted in the river. BME never heard from WQCD or <br />received WQCD's approval of this plan. WQCD thinks it is now not necessary to do this <br />task since the mine passed the WET test during for three water years (1994- 1997). <br />Besides, no mine water is discharged at this time requiring WET testing. See Appendix H <br />of the Thirteenth Annual Hydrology Report for WQCD's letter. <br />The toxicity problem with the mine water was limited to the first longwall district. Mining in <br />this district was completed in early 1993. The district has since been sealed <br />underground. There has been no pumping of accumulated water from underground <br />during this water year. <br />2.3 Red Wash Alluvial Monitoring Program <br />Portions of Red Wash have experienced subsidence due to longwall mining at the <br />Deserado Mine. As required by CMLRD (now DRMS), BME initiated a detailed hydrology <br />monitoring program in Red Wash above the first longwall panel to be mined. The <br />monitoring program consisted of nine (9) holes drilled in the Red Wash alluvium across the <br />predicted zone of subsidence from longwall panel 1 (LW -1). Water levels in the holes were <br />monitored before, during, and after active subsidence took place. The purpose of the <br />12 <br />
