Stipulation No. 13
THE PERMITTEE SHALL CONDUCT MINE INFLOW STUDIES FOR ALL ACTIVE OR
UNSEALED UNDERGROUND COAL MINE WORKINGS. ANNUAL INFLOW STUDIES SHALL BE
CONDUCTED FOR EACH ACTIVE OR UNSEALED AREA OF WORKINGS IN THE MONTH OF
JUNE, AND THE RESULTS OF EACH INFLOW STUDY SHALL BE SUBMITTED TO THE
DIVISION BY THE FIRST OF AUGUST OF THE SAME YEAR. THE MINE INFLOW
STUDIES SHALL INCLUDE:
A) THE MAPPING OF EACH POINT SOURCE INFLOW (I.E., FAULTS, FRACTURED
ROOF, FRACTURED FLOOR, EXPLORATION DRILL HOLE, ETC.) AIJD EACH AREA
WIDE INFLOW (I.E., DRAINAGE FROM SEALS TO ABANDONED MINE WORKINGS:
AREAS OF WEEPING COAL FACES, ROOF, OR FLOOR, ETC.) ON UP-TO-DATE
MINE WORKINGS MAPS;
B) PRODUCE TABLES OF ALL POINT SOURCE INFLOWS MAPPED WITH DATA ON
THEIR FLOW RATES.
C) QUALITY DATA, INCLUDING pH, ELECTRO-CONDUCTIVITY, AND TEMPERATURE
AND THE SOURCE (I.E., FAULTS, FRACTURES, DRAINAGE FROM SEALS, ETC.)
FOR ALL POINT SOURCE INFLOWS NOT PREVIOUSLY MAPPED.
D) THE SUBMITTAL OF A CONTINUOUS RECORD OF MINE DISCHARGES FOR THE
YEAR AND A HYDROGRAPH OF FLOWS.
Stipulation No: 14
PRIOR TO SECONDARY OR RETREAT MINING UNDER CIRUELA CANYON AND APACHE
CANYON DRAINAGES, THE PERMITTEE MUST COLLECT DATA ON THE QUANTITY OF
WATER FLOWING IN THESE DRAINAGES. MONITORING MUST BE SUFFICIENT TO
DIFFERENTIATE SEASONAL FLOW VARIATIONS.
PRIOR TO SECONDARY OR RETREAT MINING UNDER PETE CANYON, THE APPLICANT
SHALL PROVIDE A DESCRIPTION OF STREAM FLOW CHARACTERISTICS AIJD WATER USE
IN PETE CANYON.
THE PERMITTEE SHALL PROVIDE AN ASSESSMENT OF THE PROBABLE HYDROLOGIC
CONSEQUENCES OF SECONDARY OR RETREAT MINING ON THE QUANTITY AND QUALITY
OF SURFACE WATER IN CIRUELA, APACHE AND PETE CANYONS.
ALL h10NITORING MUST CONTINUE UNTIL DISCONTINUATION IS APPROVED BY THE
DIVISION IN WRITING.
Stipulation No. 15
THE PERMITTEE SHALL SUBMIT AN ANNUAL HYDROLOGIC MONITORING REPORT FOR THE
NEW ELK MINE. THE MONITORING REPORT SHALL INCLUDE A SUMMARY AND ANALYSIS
OF DATA COLLECTED DURING THE YEAR, INCLUDING: ~1) WATER USED IN THE
MINING OPERATION;/ 2) MINE WATER DISCHARGES TO RECEIVING STREAMS (QUANTITYf
AND~QUALITY); 3)~/MINE WATER INFLOWS (ANNUAL MINE INFLOW STUDY); 4)~STREAM
FLOWS AND QUALITY; 5) IMPACTS TO THE QUALITY AND QUANTITY OF ALLUVIAL AND
BEDROCK AQUIFERS; AND 6).%IMPACTS TO SPRING FLOWS AND QUALITY. THE
MONITORING REPORT SHOULD INCLUDE A DESCRIPTION OF MITIGATIVE MEASURES
TAKEN TO MINIMIZE DISTURBANCE TO THE PREVAILING HYDROLOGIC BALANCE. THE
