Stipulation No. 11 was made to the approval of the original permit in order to define the impacts of underground coal mining on both surface and ground water. Annual inflow studies were required for the mine, and the results were to be submitted Dy the first of August of the same year in the Annual Hydrology Report. Stipulation No. 11 was satisfied during the first permit term. The annual inflow study described on Pages 2,05,39 and 40 of the permit application is accepted as adequate for the renewal term, Information has not been supplied by the operator to completely describe the stream/a1luv~aT systems of the permit area, specifically that of Santistevan Canyon, as required by Stipulation 12 to the original permit. Santistevan Canyon could be affected by subsidence attending underlying secondary or retreat mining during the permit renewal term. In order to assess potential impacts of such mining and to verify that assessment, the applicant must adequately characterize and monitor all streams in the permit and adjacent areas. In order to comply with Rule 2.04.7(2), 2.05,6(3)(b)(iii), 2.05.6(3)(b)(iv) and 4.05.13.(2), as regards Santistevan Canyon, Stipulation 12 is retained. Stipulation 12: PRIOR 70 SECONDARY OR RETREAT MINING UNDER CIRUELA CANYON, APACHE CANYON, AND SANTISTEVAN 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. THE PERMITTEE MUST MONITOR THE QUALITY OF WATER FLOWING IN CIRUELA CANYON QUARTERLY. MONITORING MUST BE DONE AT TWO SITES, ONE ABOVE THE MINE WATER DISCHARGE POINT AND ONE BELOW TO COAL PROCESSING WASTE PILE. THE PERMITTEE SHALL PROVIDE AN AMENDMENT OF THE PROBABLE HYDROLOGIC CONSEQUENSES OF SECONDARY OR RETREAT MINING ON THE QUANTITY AND QUALITY OF SURFACE WATER IN CIRUELA, APACHE, AND SANTISTEVAN CANYONS. ALL MONITORING MUST CONTINUE UNTIL DISCONTINUATION IS APPROVED BY THE DIVISION IN WRITING. Stipulation No. 13 was made to the original permit approval in order to verify the applicant's statement of probable hydrologic consequences, identify adverse effects to the hydrologic system, and to ensure that operations are conducted to minimize disturbances to the prevailing hydrologic balance. Stipulation No. 13 was satisfied during the original permit term. The form and content, properly updated, of the Annual Report as presented in Exhibit 10 of the permit renewal application is accepted as adequate for the renewal term. m. VIII. Alluvial Valley Floors - Rules 2.06.8 and 4.24 The original findings document contains extensive narrative which relates the original determination of the existence of an Alluvial Valley Floor (AVF) at the Golden Eagle Mine in the vicinity of the Purgatoire River. The permit application also contains information concerning the "grandfathering" of the surface facilities which are located on or near the AVF. -30-
