McClane Canyon Mine AHR Information <br />4/30/97 Update <br />Permit ~ C-80-004 <br />1. AHR Due Date: A due date is not specified in either the <br />findings document or the PAP, however the PAP states that the <br />"report shall be submitted immediately after data collecting and <br />analysis." The report has typically been submitted in January, and <br />covers the preceding water year (Oct. 1 - September 30). <br />2. Specific Reporting Requirements: Page 4-14 of the <br />application outlines the ground water monitoring program, including <br />wells, mine water discharge, non-seep inflows, and water imported. <br />The text states that "results of additional monitoring will be <br />submitted to the Division in an annual hydrological report. The <br />annual report will detail inflows, discharges and consumption of <br />water within the mine and shall be structured around the normal <br />water year." <br />In actuality, the reports submitted include all surface and ground <br />water collected during the year as well as an evaluation of the <br />monitoring results with respect to the PHC projections. The <br />reports submitted are more comprehensive than specified in the PAP. <br />Ground Water <br />a. Quarterly monitoring of GW-1 and GW-3 for water level and <br />field parameters. <br />b. ~CPDES mine discharge sampling. <br />c. Non seep mine inflows. <br />d. Quantity of mine water discharge, consumption, and water <br />imported for use in the mine. <br />Surface Water <br />SW-i and SW-8 are monitored quarterly for flow, and the Lab <br />Analysis list. SW-2 and SW-5 are monitored twice a year (snowmelt <br />and rain runoff) for flow, and and the Lab Analysis list. <br />Lab Analysis List: <br />pH temperature sp. cond. TSS <br />TDS Ca Carbonate C1 <br />Mg K Na SAR <br />arsenic boron sulfate <br />copper iron lead Mn <br />Tot. hardness selenium bicarbonate Al <br />During Temporary Cessation, SW-5 is not monitored, and Lab Analysis <br />list is reduced to pH, Sp. Cond., Temp, TSS, TDS, sulfate, iron, <br />and manganese. <br />
