• monitoring stations until future disturbance is planned (Flume Stations), reduced the frequency of well monitoring, and reduced the water quality parameter list to only those parameters associated to the mining operations. In 1994, the monitoring parameters were reduced slightly and several bedrock monitoring wells were added in conjunction with the renewal. In early 1997, the monitoring plan was modified to reflect the reclamation at the site and the discontinuation of mine water discharge. In 1998, Basin Resources submitted a study to the State demonstrating the establishment of sufficient vegetation and cover [o comply with water quality standards without passing runoff through retention ponds. The Division granted approval to remove and reclaim sediment control ponds 003 and 004. Prior to this approval, monitoring of these ponds had been conducted in accordance with the NPDES permit as described in Exhibit 22, NPDES Permit, and summazized in the Annual Hydrology Reports. [n 2000, Basin Resources applied for Phase II Bond Release. In 2001 the Division approved Phase II release finding that "appropriate vegetation cover has been established and erosion has been demonstratively controlled". In reviewing the 2000 Hydrology Report the Division concluded that "surface water quality and quantity changes are small to non-existent (and that) surface water impacts are not expected (from the reclaimed mine)". Subsequently Basin requested and the Division approved modifications to the water monitoring plan discontinuing the surface water monitoring stations. Other • modifications to sampling frequency were also approved. Maps 7A and 7B, Regional Hydrology and Golden Eagle Facilities Area Monitoring Locations, presents water monitoring stations as approved in 1998. Surface monitoring stations remain shown for historical perspective. The Annual Hydrology Reports contain the methods and results of all monitoring activities. The monitoring plan is established to verify projections of probable hydrologic consequences. There are four stream monitoring- locations which will be used to verify projections of chance in water quality associated with runoff through the facilities area. Site PRS-2 is upstream of the Golden Eagle disturbance area along the Purgatoire River while PRS-3 is downstream of the disturbance area. Site CCS-1 is located upstream of the disturbance area in Ciruela Canvon and site CCS-2 is downstream of the disturbance area. There are three alluvial wells. These wells will be used to verify projections about the qualitative impacts of the recharge from the disturbed areas on alluvium. The PAW series is located along the Purgatoire River. PAW-5 is upstream of the disturbance at the Golden Eagle and PAW-6 is located adjacent to PRS-3, downstream of the facilities area. CCAW-I monitors potential effects of Golden Eagle surface facilities and the coal processing waste bank constriction in Ciruela Canyon. • 2.05-47e (TR-52 Revision - d/2/01)
