C-81-038; RESPONSE TO CDMG 1991 ANNUAL HYDROLOGY. MINE INFLOW, <br />AND SUBSIDENCE REPORT REVIEW CUNII+IENiS <br />Dear Mr. Gorham: <br />The followir-g information is submitted in response to your camnPSits regarding the <br />1991 Annual Hydrology, Mine Inflow, and Subsidence Report as detailed in your <br />oammulication of March 19, 1993. I apologize for the delay in con¢~leting this <br />response. Zhe responses correspond to the numbered oonmlents in your letter. <br />Annual Hydrologv Report <br />General Comments <br />1) No response rPrn ' ed. <br />2) I71 future submittals, to avid unnecessary confusion, maps <br />delineating all hydrologic monitoring stations will be included with <br />each Annual Hydrology Report. For the 1991 sulmittal, maps <br />submitted with the 1990 Annual Hydrology Report were referenced. <br />The 1990 AHR maps had been revised to depict the locations of all <br />monitoring points. The permit maps however, to this point do not <br />depict all of the sampling locations. <br />3) NVCC looks forward to discussing the Division's reservations with <br />respect to reduction of the hydrology monitoring program at Orchard <br />Valley. COVCC will contact you to arrange a meeting to address <br />these issues at our earliest opportunity. <br />Errors and Omissions <br />1) Pond 87 elevations will be corrected on future editions of both Map <br />No. 4-1 and Table 1. <br />2) Future editions of Table 1 will be corrected to show Spring 30 <br />elevation as 7840. <br />3) Station SW-09 was originally located in the East Roatcap drainage <br />
