<br />~ks and Gesso, LLC <br />Mining will take place using scrapers and front end loaders. Excavated material <br />will be loaded directly into haul trucks for transport from the site; however, a field <br />conveyor system may be used to convey material to the processing area. <br />Settled fines from dewatering and washing and clay material ripped from <br />claystone bedrock will be used as backfill. Slope creation and clay lining will <br />begin after excavation has reached the limit of mining along the property's <br />eastern boundary. Clay lining of the slopes to isolate the reservoir from <br />surrounding ground water will follow shortly thereafter. <br />Water Diversions and Imaoundments <br />Before beginning mining activity, water that has accumulated in the historic mine <br />will be discharged. Thereafter, surface runoff and accumulating ground water will <br />be collected in the southwest corner of the site, clarified, and discharged to the <br />Ditch. Shallow trenches will be excavated, if necessary, to enhance de-watering <br />operations. A CPDES discharge permit and formal agreement from the ditch <br />company will be obtained prior to any discharge from the mine site. The <br />Applicant will be prepared to recycle clarified water from dewatering to aggregate <br />washing operations, if necessary. As creation of slopes and clay lining proceeds <br />around the perimeter of the excavated area, inflow of groundwater will decrease. <br />Aggregate washing operations will be separate from mine dewatering activity. <br />There will be no discharge from washing operations. Wash water settling ponds <br />will be located along the excavated area's northern boundary, as shown by the <br />accompanying Mine Plan Map. Make up water will be available via a hydrant <br />permit issued by the South Adams County Water and Sanitation District and can <br />be supplemented from the mine dewatering operation. <br />Sand and Gravel Resources To Be Recovered <br />124"' Estates -Regular 112 Application 01029.WD <br />124`" Estates Partners g August 2001 <br />
