.5.1: The mine and reclamation plan proposed for the Lilly Mines site will minimize - <br />Sa the disturbance of the hydrologic balance of the Taylor Basin and Taylor Gulch <br />watershed due to mining and reclamation activities. The mine and reclamation <br />plan as described in the permit amendment application will: ~ • <br />1) Keep the natural drainage channel of Taylor Gulch open and <br />separate from drainage within the mine operation for the life of <br />mine and foreseeable future after mining. <br />2) Strive to keep mine site drainage separate from Taylor Gulch <br />drainage while returning all surface water back to Taylor Gulch <br />via percolation and infiltration at the southern boundary of the <br />affected land. <br />3) Minimize sediment delivery to Taylor Gulch from mining <br />impacts by structural and vegetative controls, specifically re- <br />vegetating all disturbed areas possible after mining. <br />4) Specifically eliminating all potentials for contamination of <br />Taylor Gulch via sediment or man-made contaminants such as <br />fuels and lubricants from heavy equipment. This will be done <br />by berm design and construction, drainage control and <br />maintenance, and proper storage and handling of fuels, <br />lubricants, and explosives. <br />5) Salvage and use all topsoil material encountered during mining <br />development and extraction_ Final grading and re-vegetation <br />efforts will be geared to promoting a stable, self-sustaining <br />ecosystem oriented to forage production for wildlife habitat. <br />Colorado Marble, Inc., will be in compliance with Colorado Water Laws and regulations <br />governing injury to existing water rights by refraining from using, con~*ning, or <br />diverting surface waters in such a way as to degrade, misappropriate, or change their <br />flow, volume, or quality to down stream holders of water rights. All diversions of surface <br />waters on site for purposes of environmental control will be made to minimize any <br />degradation of quantity or quality of said surface flow as delivered to Taylor Gulch <br />watershed. <br />i5.2!All efforts will be made to control stormwater run-off from the site via drainage <br />~ control and maintenance during life of mine and after cessation of mining. Final <br />5 grading of all disturbed areas will result instable slopes amenable to native <br />vegetation establishment and long-term success. Roadways, ditches, and storm <br />conveyances will be constructed as much as possible to flow to a low point (lower <br />pit) for long term sediment and stormwater collection with a minimum of <br />maintenance demand. Highwall benches and associated drainage structures will <br />be left in stable configuration with drainage ditches oriented to lower pit azea for <br />sediment control and direct infiltration to Taylor Gulch watershed. Man made <br />pollutants such a fuels,lubricants, and explosives will be properly stored, handled, <br />and used in accordance with best management practices. All spills of <br />
