DMG Concern <br />Springs <br />Most metals are missing from the November sample of spring 303-1. This was also <br />the case in the previous year, and the response indicated this was appropriate as per <br />the plan. Please explain. <br />TCC Response <br />The enclosed Table B from the TCC permit shows the required metals for analysis. Due to <br />a report glitch, a portion of the metals for the November samples were coded as dissolved vs. <br />total recoverable. As can be seen from the attached data sheets received from ACZ, the <br />parameters in question were indeed analyzed for total recoverable metals, similar to that from <br />the previous year. This error in the report was not caught during checks for parameter <br />analysis. TCC apologizes for the reporting format error, and will continue to work in rectifying <br />this problem. The revised data sheets are enclosed. <br />DMG Concern <br />Water Quality Analysis <br />Bedrock Wells <br />Well 006-83-48C will be replaced as per the minor revision (MR-92) issued 7/23193. <br />Monitoring will begin with the 1994 water year (October 1993 sampling). This well <br />is apparently contaminated by casing grout, accounting.for the high EC readings since <br />1989. <br />TCC Response <br />The replacement well is currently being constructed, and should allow for monitoring in <br />October 1993. The initial monitoring will be reported in the 1993 AHR. <br />DMG Concern <br />2. Well FBR-1 tA, a Wadge overburden well recently acquired from Pittsburgh & Midway <br />shows dissolved solids in the 2000 ppm range. This is double the baseline Wadge <br />TDS. What is the explanation for the elevated TDS observed? Does P&M have any <br />baseline monitoring data for this well? <br />TCC Response <br />Our review of records for this well do not indicate the presence of any baseline monitoring <br />data for well FBR-1 1 a. A possible explanation for the higher TDS level in this well is the <br />completion of this well as compared to other wells completed by Cyprus for the monitoring <br />of the Wadge Overburden. It has been Cyprus' practice to complete Wadge monitoring wells <br />from the top of the Wadge coal seam up to the "C" sandstone, although this is not a <br />requirement. Well FBR-11A, on the other hand, is open from the Wadge coal seam up <br />through the "C" sandstone and the overlying Lennox coal seam, with the associated <br />overburden. This may be a factor in the observed TDS levels for this particular well. TCC will <br />continue to monitor this well in accordance with the approved plan. <br />
