2.05.3 <br />shown on Map 39. The Quonset but has been removed from the site. <br />Sewage Treatment Plant <br />A package sewage treatment plant located near the D -Seam portal level. The <br />building is approximately 20 foot by 30 foot with a 10 foot eave height. <br />Water Tanks <br />A water tank located on the utility level which is above the portal level. The <br />fabricated steel tank is constructed on an oiled sand base. The tank is <br />approximately 52 feet in diameter and 32 feet high which provides a capacity of <br />approximately 500,000 gallons. <br />A 50,000 water tank for the B -Seam Portal is located above the portal, west of the <br />downhill conveyor transfer building. <br />A water tank is located above and west of the preparation plant. This tank will have <br />a capacity of about 140,000 gallons (32 foot diameter). <br />Water Treatment Buildinq <br />This pre- engineered metal building is located east of the water tank. It is <br />approximately 14 feet by 20 feet with a 12 foot eave height. <br />Mine Vent Fans <br />The 8 -foot diameter ventilation fans have been removed from the D -Seam and 13- <br />Seam portal benches. A fan and fan shaft were constructed on the utility bench <br />during the last quarter of 1998 and early 1999. The fan is 10 -feet in diameter. A <br />mirror image standby ventilation fan was constructed at the utility bench during <br />2003. See Maps 15 -2 and 33. A vent shaft was developed in Freeman Gulch in <br />2000. The 400 foot deep exhaust shaft was lined with a 6 -foot diameter steel liner <br />plate. A 10 -foot diameter fan and associated duct work was installed on the <br />Hubbard Creek shaft during 2009. The Freeman Gulch and Hubbard Creek shafts <br />have been backfilled and capped. The Hubbard Creek vent fan has been removed. <br />Power Line <br />A high voltage overhead power line extends from the existing Delta Montrose <br />Electric Power line to the portal area substation. The power line is approximately <br />5,600 feet long. Approximately 750 feet of new power line will be constructed for the <br />downhill conveyor. About 500 feet will be constructed at the portal bench and 250 <br />feet at the highway stockpile area. The B -Seam portal bench required another 200 <br />feet of powerline. <br />TR -91 2.05-16- 10/14 <br />
