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 THROUGH 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.

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 #3
THE OPERATOR WILL PROVIDE THE DIVISION WITH A DETAILED SUMMARY OF
THE COSTS THAT WOULD BE INCURRED BY THE STATE TO INSTALL
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 #4
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.
