Permit 'lumber CO-0068, ( ) Page 5 of 7 Attachment 1 Special Stipulations 1. Prior to sediment pond construction, the permittee will submit to the Regulatory Authority revised pond designs which will insure that runoff stor- age capacity will not be reduced by ground water draining into the pond at any time during the year. Furthermore, the plan will include a proposal for lin- ing the pond, or otherwise preventing the contamination of near surface ground water as a result of percolation through the alluvium. 2. Within one month of permit issuance, the permittee will submit to the Regulatory Authority a revised plan for handling possible flooding of portions of the permit area. The plan will include an evaluation of alternative flood control techniques and potential downstream effects of any flooding in the area will be included in the evaluation. 3. Within one month of permit issuance, the permittee will submit to the Regulatory Authority a detailed plan for handling and treating any discharge of ~,aater from the underground workings which does not meet the effluent limit- ations of 4.05.2. The plan will address the measures to be used to prevent or control gravity discharge including conveyence to, maintenance of, and dis- charge from sumps, sedimentation ponds or a treatment facility on the permit area. ~ 4. The applicant will submit to Regulatory Authority an annual report of in- flaws, discharges and consumption of water within the Bear ~3 mine. This re- port is to include a mine workings map showing the location and quantity of inflows; a table keyed to the mine map which shall contain the source (i.e., fault, fractures,. etc.), quantity, duration and quality (i.e., pH, electrc- conductivity and temperature) of all inflows; a table containing records of water discharged from the mine, consumed in the mine and imported for use - within the mine; a discussion of water balance within the mine; and finally, a projection of hydrologic impacts of mining in the upcoming year. 5. Bear Coal Company shall continue to monitor the three Yorth Fork alluvial wells to monitor the effects of mining on alluvial ground water. This moni- toring shall include monthly monitoring of ground water levels, pH, temper- ature and electro-conductivity. On a quarterly basis, ground water quality analyses shall be run on samples collected from these alluvial wells. The water quality samples shall be analyzed for those parameters in Attachment 2 of the CLh1RD permit. All data shall be submitted to The Regulatory Authority within one month of the date of collection. The Regulatory Authority may reduce this frequency of analysis, the number of parameters analyzed, and num- ber of wells monitored upon completion of the year's collection of dato. 6. The permittee will submit to the Office of Surface dining an annual hydrologic report. This report shall include an analysis of all hydrologic data gathered during the year, an assessment of the impacts of mining during the year, and an assessment of the projected impacts of mining in the ~ following year. This report shall assess the impacts of mining on the quality and quantity of water in surface streams, springs, ground water aquifers, mine inflow, and mine discharges. , ~~, iii ~ "s , I . ;
