This report <br />shall first discuss the effect of McClane Canyon mine on the local <br />bedrock aquifer, next discuss the effect of Munger Canyon mine, <br />and last discuss the efect of both mines on the hydrology of East <br />Salt Creek. <br />McCLANE CANYON MINE <br />Mine History <br />The mine remains under Division approved Temporary Cessation. <br />Maintenance work and a test section of a rock slope were done at <br />the mine during the last year. Maintenance work included such <br />things as enhancing surface water controls, supplimental <br />underground roof support, pumping water from the mine, and the <br />general upkeep of equipment. A rock slope test entry, 80 feet <br />long, was driven late in 1986. The purpose of the test was to <br />determine if Salt Creek could drive a set of slopes from the <br />graben through the East fault to access the upthrown block of <br />Cameo coal. The test was undertaken after consultation with CMLR <br />officials to determine if the material could be disposed <br />underground without triggering additional permitting requirements. <br />The test area was on the eastern extreme of the main entries as is <br />shown on Figure 1, the mine workings map. All material cut in the <br />rock slope was disposed of underground in the No. 2 Sump. <br />• Water Inflow L Discharge <br />Since there was no coal mining during the year, no additional <br />ground was opened up to supply additional water to the mine. The <br />inflow of water seems to have stabilized at about 1.2 gallons per <br />minute based upon discharge records for the last two years. A <br />
