• s <br />~ ~ ._~; ~ ; <br />~~ <br />V. Plant Description <br />The plant will consist of a reagent feeding building which will house <br />a lime and polymer feed system. 'These systems will consist of two 6-foot by <br />6-foot diameter tanks and mixers which feed chemical reagents to a weir box <br />prior to the discharge entering the thickener, <br />An accelerator or thickener tank, approximately 35 feet in diameter, <br />will be used to remove suspended solids and heavy metal ]rydroxides. A twelve-inch <br />buried pipeline will bring the mine ~•rater from the portal to the plant and a <br />four-inch buried pipeline will return the sludge fran the thickener to the flo- <br />tation plant. <br />Electrical equipment will consist o.f a buried power line, reagent and <br />mix feeders, pumps and thickener rake drives. Connected horsepower is estimated <br />to be not more than 50. Plate I and Plate II illustrate the equipment and arrange- <br />ment of the plant. <br />Estimated cost of the facility is $250,000 and operational costs are <br />estimated at $40,000 per year. <br />~• VI. Location of 14ater Treatment Plartt <br />The water treatment plant mill be located on the east side of 1Vindy <br />Gulch just opposite the mine shop buildings. Access will make use of an exist- <br />ing road and storage area. At the present time ventilation ducting and electric <br />cable are being stored on the pad, Approximately 1000 - 2000 yards of material /', <br />will be removed to level the site. This material will be removed or contoured ~ <br />in with the present slope. Reseeding mill Ue accomplished a:Eter construction <br />is complete. <br />A surface map is attached to show the general arrangements of the plant <br />facilities in relationship to existing facilities, <br />VII. Pollution Considerations <br />'there will be some increase in noise, air, and water pollution rhir.ing <br />construction which is common to all such building projects. Every effort will <br />be taken to minimize pollution during this period. As no toxic chemicals twill <br />be used in the treatment process, crater quality will not be affected by minor <br />spills of reagents. Noise pollution will be minimal and should not be noticc- <br />able to nearby residents. Visual pollution will have little impact because of <br />existing structures near the mine portal. <br /> <br />- ls2 - <br />
