<br />F) ANNUAL MONITORING (NOVEMBER) OF THE ALLUVIAL WELLS ALONG THE MIDDLE
<br />FORK ABOVE AND BELOW THE ALLEN MINE. THE PARAMETERS TO BE
<br />MONITORED INCLUDE GROUND WATER LEVELS, FIELD pH, FIELD
<br />ELECTRO-CONDUCTIVITY, FIELD WATER TEMPERATURE, TOTAL DISSOLVED
<br />SOLIDS AND DISSOLVED IONS MEASUREMENTS FOR CARBONATE, BICARBONATE,
<br />CHLORIDE, SULFATE, SULFIDE, AMMONIA, NITRATE/NITRITE, CALCIUM,

<br />• DETERMINATION OF SAR.
<br />G) SUBMIT ALL SURFACE ANO GROUND WATER MONITORING DATA QUARTERLY.
<br />H) MONITORING REQUIREMENTS MAY BE REDUCED BY THE DIVISION UPON THE
<br />SUBMITTAL OF ADDITIONAL DATA AND A FORMAL REDUCTION REQUEST.
<br />Stipa]ation No. ]3:
<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 7HE MONTH OF
<br />JUNE, AND THE RESULTS OF EACH INFLOW STUDY SHALL BE SUBMITTED TU 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.) AND EACH AREA
<br />WIDE INFLOW (I. E., DRAINAGE FROM SEALS TO ABANDONED MINE 'dORKINGS:
<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.
