XXI. Sealino of Drilled Holes and Underground es Information on the sealing of exploration and mine holes is found in Section 2.05.3 of the permit application. The proposed operation is in compliance with the requirements of this section. XXII. Subsidence - Rules 2.05.6(6) and 4.20 Subsidence information may be found in the permit application, Section 2.05 and in PAR Responses. Past mining in the Coal Gulch area has resulted in subsidence. Subsidence has manifested itself on the surface as fractures, and is theorized to have caused rubbilization (bulking) and bed separation in both the Menefee Formation, and the Cliff House Sandstone. This theory is based on the amounts of water which have been measured discharging from the abandoned Victory No. 1 portal. Maximum portal discharge approached 25 gal/min in early spring, 1985, while in late May, 1985, discharge was measured at 8 gal/min. The applicant noted that some water was discharging from the portal during the summer of 1984. The Victory No. 1 portal was re-opened by the Arness Mc Griffin Coal Company operation, which induced portal discharge at this location. In 1984, Peerless Resources sealed the Victory No. 1 portal, leaving a drain pipe at the top of the seal to drain excess water from the mine. The operator is responsible for the proper handling (treatment, storage and eventual discharge to Coal Gulch) of this water. The operator is not responsible for the handling of the Victory No. 3 portal discharge, but has committed monitoring quantity and quality of this water to better define the impacts of the Coal Gulch Mine on the Coal Gulch surface water system. Monitoring will be accomplished by welding a stand pipe onto the existing discharge pipe, thus separating this water from the stream flow. Quantity (flow) will be measured on a monthly basis in gallons per minute. Quality will be measured quarterly for the parameters listed in the ground water subsection of Section V. As stated above, the abandoned Victory No. 3 portal also discharges water, however, the discharge outlet is located on the bottom of the Coal Gulch Creek bed. This discharge caused a noticeable upwelling in the stream. This upwelling discharge, while believed to be flowing more water, is assumed to be equal to the Victory No. 1 discharge. Based on measurements made by the Di vi son in mid-June, 1985, the quality of this discharge is though to be better then that from the Victory No. 1 portal. On June 13, 1985, the Victory No. 3 field parameters were: Temperature = 12oC; Specific Conductivity = 790 umhos; and, pH = 6.73.
