<br />D) ANNUAL MONITORING (NOVEMBER) OF THE PURGATOIRE RIVER UPSTREPM OF
<br />THE MAXWELL MINE, THE PURGATOIRE RIVER BELOW THE CONFLUENCE WITH
<br />CIRUELA CANYON (OLD CHANNEL) AND THE MAXWELL MINE DISCHARGE. THE
<br />PARAMETERS TO BE MONITORED INCLUDE THE FIELD PARAMETERS IDENTIFIED
<br />ABOVE IN THIS STIPULATION, DISSOLVED OXYGEN, TURBIDITY, TOTAL
<br />SUSPENDED SOLIDS, TOTAL COMBUSTIBLE SOLIDS, TOTAL DISSOLVED SOLIDS,
<br />TOTAL HARDNESS, AND TOTAL RECOVERABLE MEASUREMENTS FOR THE IONS
<br />CARBONATE, BICARBONATE, CHLORIDE, SULFATE, AMMONIA,
<br />NITRATE/NITRITE, CALCIUM, MAGNESIUM, POTASSIUM, SODIUM, BORON,
<br />CADMIUM, COPPER, IRON, LEAD, MANGANESE, MERCURY, NICKEL, SELENIUM,
<br />ZINC, SILVER, AND A DETERMINATION OF SAR.
<br />E) ANNUAL MONITORING (NOVEMBER) OF THE PURGATOIRE RIVER ALLUVIAL WELLS
<br />ABOVE AND BELOW THE MAXWELL MINE AND THE CIRUELA CANYOrJ ALLUVIAL
<br />WELL BELOW THE DISPOSAL PILE. THE PARAMETERS TO BE MONITORED
<br />INCLUDE GROUND WATER LEVELS, FIELD pH, FIELD ELECTRO-COrDUCTIVITY,
<br />FIELD WATER TEMPERATURE, TOTAL DISSOLVED SOLIDS AND DISSOLVED IONS
<br />MEASUREMENTS FOR CARBONATE, BICARBONATE, CHLORIDE, SULFATE,
<br />SULFIDE, AMMONIA, NITRATE/NITRITE, CALCIUM, MAGNESIUM, POTASSIUM,
<br />SODIUM, BORON, CADMIUM, COPPER, IRON, LEAD, MANGANESE, MERCURY,
<br />NICKEL, SELENIUM, ZINC, SILVER, AND A DETERMINATION OF SAR.
<br />F) SUBMIT ALL SURFACE AND GROUND WATER MONITORING DATA QUARTERLY.
<br />• G) MONITORING REQUIREMENTS MAY BE REDUCED BY THE DIVISION UPON THE
<br />SUBMITTAL OF ADDITIONAL DATA AND A FORMAL REDUCTION REQUEST.
<br />Stioulation No. 11
<br />THE PERMITTEE SHALL CONDUCT MINE INFLOW STUDIES FOR ALL ACTIVE OR
<br />UNSEALED UNDERGROUND COAL MINE WORKINGS. ANNUAL INFLOW STUDIES SHALL BE
<br />CONDUCTED FOR EACH ACTIVE OR UNSEALED AREA OF WORKINGS IN THE MONTH OF
<br />JUNE, AND THE RESULTS Of EACH INFLOW STUDY SHALL BE SUBMITTED TO THE
<br />DIVISION BY THE FIRST OF AUGUST OF THE SAME YEAR. THE MINE INFLOW
<br />STUDIES SHALL INCLUDE:
<br />A) THE MAPPING OF EACH POINT SOURCE INFLOW (I.E. FAULTS, FRACTURED
<br />ROOF, FRACTURED FLOOR, EXPLORATION DRILL HOLE, ETC.) AWD EACH AREA
<br />WIDE INFLOW (I.E., DRAINAGE FROM SEALS TO ABANDONED MINE WORKINGS:
<br />AREAS OF WEEPING COAL FACES, ROOF, OR FLOOR, ETC.) ON UP-TO-DATE
<br />MINE WORKINGS MAPS;
<br />B) THE PRODUCTION OF TABLES OF ALL POINT SOURCE INFLOWS MAPPED WITH
<br />DATA ON THEIR FLOW RATES.
<br />C) QUALITY DATA, INCLUDING pH, ELECTRO-CONDUCTIVITY, AND TEMPERATURE,
<br />AND THE SOURCE (I.E., FAULTS, FRACTURES, DRAINAGE FROM SEALS, ETC.)
<br />FOR ALL POINT SOURCE INFLOWS NOT PREVIOUSLY MAPPED.
<br />D) THE SUBMITTAL OF A CONTINUOUS RECORD OF MINE DISCHARGES FOR THE
<br />• YEAR AND A HYDROGRAPH OF FLOWS.
