2.05 APPLICATION FOR PERMIT FOR SURFACE OR t1NDERGROUND MINING ACTIVITIES -
<br />MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS.
<br />Water Supply
<br />Water for mine uses, such as fire fighting, underground and
<br />surface dust suppression, and sanitary and domestic needs of
<br />mine personnel was partially obtained from the Steven's Gulch
<br />well field. The well field construction was started in March,
<br />1977, and completed in February, 1978. It is located in the
<br />SNNW'4, Section 13, T.13.S., R.92.W., 6th P.M. (see Map 8A-8).
<br />The facilities constructed here are wells, pumps, water piping,
<br />well house storage tank, and a 500,000 gallon water storage
<br />tank. The water is obtained from well SG-1. Other wells are
<br />used for observation and monitoring (see Section 2. O5. 6 (3)
<br />for details). As mentioned earlier, water is pumped from well
<br />SG-1 and the 500,000 gallon water tank into the storage tank for
<br />further pumping into the pipeline to the 300,000 and 100,000
<br />gallon tanks at the mine site. The well house storage tank,
<br />pumps, and well are enclosed by a building to minimize visual
<br />impacts and weather problems. The 500,000 gallon water storage
<br />tank was constructed in 1981, 100 feet south and slightly west
<br />of the well house. Water is piped by the Pitkin Mesa Pipeline
<br />Company from springs located approximately two miles north of
<br />the long-term lease area and within the Terror Creek drainage.
<br />At cessation of mining, the 500,000 gallon water tank and
<br />associated access and maintenance easements will be transferred
<br />to the Pitkin Mesa Pipeline Company.
<br />The location of the water supply lines in presented on Map 9-7
<br />Structures in the Volume 9 - Environmental Resources Appendices
<br />and on Map 8A-6.
<br />Sedimentation Ponds - Mine Site
<br />Four sedimentation dams were constructed from September, 1978,
<br />to June, 1979, between elevation 6,775 feet and elevation 6,600
<br />feet of the mine Permit area. They are located directly south
<br />of the mine site immediately downstream from the reclaimed and
<br />West Ridge waste disposal sites in the S'~SE',SE,, Section 24 and
<br />the NE <SE <, SE3sNE~, (North of Steven's Gulch road), Section 25,
<br />T.13.5., R.92.W., 6th P.M. (see Map B-1).
<br />These ponds were designed and constructed with the input of
<br />Chuck Leaf P.E., a consulting civil engineer and hydrologist,
<br />and after consultation and approval of the Office of Surface
<br />Mining, the U.S. Geological Survey and the Division of Minerals
<br />& Geology. See Map No. BA-1, Construction Specifications for
<br />Sedimentation Ponds, and Pond Construction Certifications in the
<br />Ponds, Impoundments, and Dams Appendix in Volume 8A.
<br />The ponds conform to 9.05.2, .5, .6, .7, and .17.
