Projection of Maximum Disturbance Presently, 20 acres of disturbed land exists at the site. While reclamation activities will begin during 2005, disturbed lands vs. reclaimed land areas will continue to grow for the next several seasons to facilitate highwall development and access to the mazble bed. It is estimated that maximum disturbed lands will tota135-40 acres by 2015, with approximately 10 acres under reclamation. After that time period, additional acreage mined and newly reclaimed land areas will more or less equal each season until annual reclaimed land areas aze equal to or more than mined acreages during the last ten yeazs of life of mine. During the last five yeazs of life of mine, the operator will double the acres of reclaimed land vs. acres mined, as permanent highwall reclamation and re-vegetation work proceeds along the footwall zone of the greater portion of the western side of the affected land area. Water Diversions Water diversions will include shallow surface drainage diversions located above the highwall bench system and topsoil stockpile area on the west side of the affected land area. These diversions will be a "v" shaped ditch running parallel to and down gradient from the west boundary line of the affected land, app. 3 feet deep and no less than 10' across with a more defined cut on the highwall side. The ditch will be installed to drain surface run-off and seasonal drainage from abandoned mining pits and exploration sites on slopes directly above the affected land boundary. The ditch will be installed at a 1 grade to drain south towards the southwestern comer of the affected land, then connect to a diversion ditch directing surface flows to the lower pit location at the southwestem corner of the presently disturbed area. Ditch systems of similaz configuration will also be installed at the toe of each highwall face run and topsoil pile on the upper bench system to direct surface flows to the south to intercept the lower pit. Other water diversions within the affected land boundaries include a berm constructed along the west side of Taylor Gulch, paralleling the drainage channel from the upper reaches of the mine site to the lower staging azea where Taylor Gulch drops away from the disturbed land of the mining area. The berm will be app. 4 feet high, 4-6 feet across the flattened top, and side slopes of no greater than 2:1, H:V. The berm will be capped with no less than 6 inches of topsoil and planted according to site seed mix and rate established in the reclamation plan portion of this document. The berm will help to insure separation of Taylor Gulch drainage from mine site drainage and will remain as a permanent feature after final mine reclamation activities aze completed. Road ditches within the active mining area will be constructed as needed to divert surface flows from within the active mining area, including ramps, roadways, and stockpile areas into the lower pit azea. These road ditches will likely be constructed as "v" shaped ditches along roadway shoulders and broad swales across flatter stockpile areas just deep enough to insure proper drainage of the area while allowing for equipment crossing. 10
