COMMITMENT 11
THE OPERATOR UNDERSTANDS THAT ANY NEW SEEPS OR ANY CHANGES IN WATER
QUALITY OR QUANTITY ISSUING FROM KNOWN SEEPS IN THE AREA OF THE
SUNNYSIDE MINE, FOLLOWING THE INSTALLATION OF BULKHEAD SEALS IN THE
UNDERGROUND WORKINGS, ARE REGARDED BY THE WATER QUALITY CONTROL
DIVISION TO BE UNPERMITTED POINT SOURCE DISCHARGES. THE DIVISION
OF MINERALS AND GEOLOGY UNDERSTANDS THAT THE OPERATOR DOES NOT
AGREE WITH THIS INTERPRETATION BY THE WATER QUALITY CONTROL
DIVISION. THE OPERATOR FURTHER UNDERSTANDS THAT ANY MEASURABLE
CHANGE IN WATER QUALITY OR QUANTITY IN THE SEEPS OR THE DRAINAGES
SURROUNDING THE MINE, i.e. CHANGES REPORTED BY THE OPERATOR IN
CONJUNCTION WITH COMPLIANCE WITH THE APPROVED HYDROLOGIC MONITORING
PLAN OR CHANGES REVEALED THRU DIVISION INSPECTIONS OF THE MINE,
WILL BE CONSIDERED BY THE DIVISION AS POSSIBLE EVIDENCE OF THE
DEVELOPMENT OF UNPERMITTED POINT SOURCE DISCHARGES RELATED TO THE
INSTALLATION OF THE BULKHEADS. THEREFORE, SIGNIFICANT CHANGES IN
WATER QUALITY OR QUANTITY IN THE SEEPS OR IN THE DRAINAGES
SURROUNDING THE MINE, FOLLOWING THE INSTALLATION OF BULKHEAD SEALS
IN THE UNDERGROUND WORKINGS, WILL BE CITED AS A POTENTIAL
COMPLIANCE PROBLEM BY THE DIVISION AND THE OPERATOR WILL BE
REQUIRED BY THE DIVISION TO CONTACT THE WATER QUALITY CONTROL
DIVISION TO DETERMINE IF A NEW DISCHARGE PERMIT FOR THE MINE OR A
MODIFICATION OF THE EXISTING DISCHARGE PERMIT FOR THE MINE IS
NECESSARY. RESPONSIBILITY FOR ENFORCEMENT OF POTENTIAL DISCHARGE
PERMIT COMPLIANCE PROBLEMS WILL REST WITH THE WATER QUALITY CONTROL
DIVISION.
COMMITMENT 12
THE OPERATOR WILL CREATE A SEPARATE SECTION IN EACH ANNUAL
RECLAMATION REPORT THAT WILL INCLUDE DATA AND NARRATIVE TO
DISSEMINATE INFORMATION FROM THE MONITORING PROGRAM REQUIRED BY THE
TERMS OF TR-14. THE OPERATOR WILL NOTIFY THE DIVISION IMMEDIATELY
IN THE CASE THAT TRACER IS DETECTED AT ANY POINT BY THE MONITORING
PROGRAM, OR IF THERE IS INCREASED DISCHARGE TO ANY SURROUNDING
DRAINAGE THAT MAY BE RELATED TO FLOODING OF THE SUNNYSIDE WORKINGS.
COMMITMENT 13
THE OPERATOR WILL PROVIDE THE DIVISION WITH A DETAILED SUMMARY OF `
THE COSTS THAT WOULD BE INCURRED BY THE STATE TO INSTAL REPLACEMENT
BULKHEADS IN THE EVENT OF PERMIT REVOCATION AND BOND FORFEITURE.
A BOND, IN AN AMOUNT APPROVED BY THE DIVISION, MUST BE IN PLACE FOR
BULKHEAD REPLACEMENT PRIOR TO CLOSING THE AMERICAN TUNNEL VALVE.
COMMITMENT 14
THE OPERATOR WILL PROVIDE THE DIVISION WITH A PLAN TO CHARACTERIZE
CONJUNCTIVE FLOW WITHIN THE CEMENT CREEK DRAINAGE IN THE VICINITY
OF THE SUNNYSIDE MINE WITHIN 30 DAYS OF REVISION APPROVAL.
