The operator described the water management system <br />that has been installed in the Phil Sheridan Tunnel; this system was not physically <br />inspected: A concrete coffer dam has been installed in the tunnel inby of the area of <br />current mining. Water collected behind the coffer dam ie routed into a PVC pipe and is piped <br />past the area of mining activity. <br />The portal area of the Phil Sheridan Tunnel was inspected. Several small frozen pools were <br />observed in the portal area. No discrete discharge was observed at the time of this <br />inspection. The draw adjacent to the portal location (which ie tributary to Four Mile Canyon <br />Creek) was dry at the time of this inspection. The operator reported that water samples from <br />the Phil Sheridan Tunnel were collected and analyzed prior to connecting the shaft with the <br />pre-existing tunnel. The operator has also collected a water sample from a domestic well <br />just north of the shaft, and is awaiting analytical data from this sample to include in a <br />pending application for a CDPS Permit. Ae specified in the 10/11/95 site inspection report, <br />analytical data from water samples must be copied to the Division of Minerals and Geology in <br />order to aid in any aeeesement of the potential for ground water impacts. <br />The operator has now discontinued waste rock disposal into the historic shaft east of the <br />mine yard. Waste rock in the backfilled shaft has been mounded above the ground surface. <br />Once the waste rock backfill has settled, it will have to be levelled, topeoiled, and <br />revegetated. Additional waste rock that is generated will be disposed of within the fenced <br />mine yard area. The operator reported that topsoil has already been stripped from the area <br />where waste rock will be piled. <br />cc: Carl Mount, DMG <br />Bob Shukle and <br />Kathleen Sullivan <br />Colorado Dept. of Public <br />Health and Environment <br />WQCD-PE-B2 <br />4300 Cherry Cr.
