-39- The applicant does not have adequate hydrologic baseline data and analysis for areas outside the Stonewall Valley. The Division is unable to make findings about the hydrologic effects of secondary or retreat mining upon those areas and whether the effects of mining would cause material damage. Therefore, secondary or retreat mining cannot be approved in those areas until the applicant supplies sufficient information to make the required findings. The Division can find that the proposed developmental mining operations have been designed to prevent material damage to the hydrologic balance outside the proposed permit area. HYDROLOGIC MONITORING The mining company is required under Rule 4.05.13(1) and (2) to monitor the effects of underground mining activities upon the quantity and quality of ground water and surface water. This monitoring is required to judge the compliance of the operator with the water quality provisions of the Colorado Surface Coal Mining Reclamation Act. The water quality provisions of the Act require that the operator shall in no case violate Federal and State water quality statutes, regulations, standards, or effluent limitations. As a matter of policy, the Division has adopted the Department of Health's Receiving Stream Standards as one of the standards by which impacts to the hydrologic balance from mining are judged. Other standards are developed and used by the Division when appropriate. Receiving stream standards have been established for the Purgatoire River. The applicant must also demonstrate an ability to comply with the NPOES effluent limitations. Rule 4.05.13(1)and (2) do not apply strictly to point discharges as does the NPDES permit issued by the Colorado Health Department. The rules in 4.05.13(1) require monitoring of non-point discharges and ground water. To ensure that the effects of the surface and underground mining activities on the quantity and quality of surf ace and ground water in the permit and adjacent areas are adequately monitored, the following stipulations to the permit document are required in accordance with Rules 2.05.6(3)(e)(i.ii), 4.05.13(1) and 4.05.13(2). Stipulation No. 12 AFTER A THOROUGH REVIEW OF THE BASELINE WATER QUALITY DATA, THE OVERBURDEN CHEMISTRY DATA SUBMITTED BY CF&I, AND THE RECEIVING STREAM STANDARDS, THE DIVISION REQUIRES MONITORING TO INCLUDE THE FOLLOWING: A) MONTHLY MONITORING OF THE PURGATOIRE RIVER UPSTREAM OF THE ALLEN MINE, AND THE PURGATOIRE RIVER BELOW THE COAL REFUSE PILES, AND THE ALLEN MINE DISCHARGE. THE PARAMETERS TO BE MONITORED INCLUDE FLOW, FIELD pH, FIELD ELECTRO-CONDUCTIVITY AND FIELD WATER TEMPERATURE. B) MONTHLY MONITORING OF THE ALLUVIAL WELLS ALONG THE MIDDLE FORK UPSTREAM AND DOWNSTREAM OF THE ALLEN MINE. THE PARAMETERS TO BE MONITORED INCLUDE GROUND WATER LEVELS, FIELD pH, FIELD ELECTRO-CONDUCTIVITY, AND FIELD WATER TEMPERATURE.
