<br />C) MONTHLY MONITORING OF THE ALLUVIUM OF APACHE, CIRUELA, AND PETE
<br />CANYONS FOR GROUND WATER LEVELS.
<br />D) QUARTERLY MONITORING, (FEBRU/,iRY, MAY, AUGUST, AND NOVEMBER) OF
<br />ALLEN MINE DISCHARGE. THE PARAMETERS TO BE MONITORED INCLUDE FLOW,
<br />FIELD pH, FIELD ELECTRO-CONDUCTIVITY, FIELD WATER TEMPERATURE,
<br />TURBIDITY, TOTAL SUSPENDED SOLIDS, TOTAL DISSOLVED SOLIDS, TOTAL
<br />COMBUSTIBLE SOLIDS, TOTAL HARDNESS, TOTAL IRON, TOTAL MANGANESE,
<br />AND PARAMETERS REQUIRED UNDER THE PERMITTEE'S NPDES PERMIT.
<br />E) ANNUAL MONITORING (NOVEMBER) OF THE MIDDLE FORK OF THE PURGATOIRE
<br />RIVER UPSTREAM OF THE ALLEN MINE, BELOW THE COAL REFUSE PILES AND
<br />THE ALLEN MINE DISCHARGE. THE PARAMETERS TO BE MONITORED INCLUDE
<br />THE FIELD PARAMETERS IDENTIFIED ABOVE IN THIS STIPULATION, PLUS
<br />DISSOLVED OXYGEN, TURBIDITY, TOTAL SUSPENDED SOLIDS, TOTAL
<br />COMBUSTIBLE SOLIDS, TOTAL DISSOLVED SOLIDS, TOTAL HARDNESS, AND
<br />TOTAL RECOVERABLE MEASUREMENTS FOR THE IONS CARBONATE, BICARBONATE,
<br />CHLORIDE, SULFATE, AMMONIA, NITRATE/NITRITE, CALCIUM, MAGNESIUM,
<br />POTASSIUM, SODIUM, BORON, CADMIUM, COPPER, IRON, LEAD, MANGANESE,
<br />MERCURY, NICKEL, SELENIUM, ZINC, SILVER, AND A DETERMINATION OF SAR.
<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 RND DISSOLVED IONS MEASUREMENTS FOR CA{280NATE, BICARBONATE,
<br />CHLORIDE, SULFATE, SULFIDE, AMMONIA, NITRATE/NITRITE, CALCIUM,
<br />MAGNESIUM, POTASSIUM, SODIUM, BORON, CADMIUM, COPPER, IRON, LEAD,

<br />DETERMINATION OF SAR.
<br />G) SUBMIT ALL SURFACE AND GROUND WATER MUNITDRING 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 />Inflow monitoring and mine discharge monitoring are essential in defining the
<br />impacts of underground coal mining on both surface and ground waters. The
<br />following changes in the monitoring plan are necessary in order to comply with
<br />Rules 2.05.6(3)(b)(iii) and 4.05.13(1). ,
<br />Stipulation No. 13
<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:
