STORMWATER MANAGEMENT PLAN <br />LINCOLN COUNTY <br />PICKENPAUGH PIT <br />As required by the State of Colorado Department of Health to reduce the chance of any possible <br />pollutants reaching any waters of the State of Colorado, let this serve as a Storm water <br />Management Plan that can be modified as needed should any of the Lincoln County mining <br />practices/operations change within streambeds of rivers and creeks within Lincoln County. Or <br />should any open pit within the County be located, have the sloping changed to allow stormwater <br />to come in contact with any waterway that would drain into a State waterway. <br />Lincoln County does/nor should not need to store any materials on site. All equipment used in the <br />removal of material from the site is trucked in, bulldozers and or end-loaders fully fueled and <br />removed once the work is complete. All fueling or repairs shall/does take place on the haul road or <br />loading area well away from any bank, or stream bed within any creek, being used to mine sand <br />and gravel. Overburden is rarely contacted in the stream- bed, and very little topsoil, if any, is ever <br />stocked piled while mining out of a streambed. All/any overburden, or topsoil that needs to be <br />stockpiled until reclamation is seeded and allowed to stabilize well away from the banks of the <br />creek or streambed. All material that is removed from the streambed is removed from the site. <br />Stockpiles are minimal, and rarely left. <br />Sand and Gravel pits within Lincoln County are located well away from any drainage areas that <br />would allow water to enter Colorado Waters as defined, the storm water remains within the pit <br />area until it perks through the soil. All operations are used less than 180 days per year. <br />The District Road Foreman for district 3 shall be responsible to assure this plan is followed, and <br />all Best Management Practices are implemented and up-dated as needed to insure any stormwater <br />that may enter the streambed of Horse Creek has not been polluted by poor management practices. <br />BEST MANAGEMENT PRACTICES <br />At no time will any mining activity take place when there is water in the pit area. <br />All overburden and topsoil shall be seeded to allow for revegetation to take place in order to <br />control stormwater run off. <br />Any needed refueling shall take place away from the pit area, on the haul road or parking area <br />with extra care given to avoid any spills. Should a spill happen, the area shall be cleaned by <br />removing any soil/material to a depth of one (I) foot and twice the size of the spill area, and <br />removed from the site. This will also apply to any other fluids that may need to be added, or <br />should any hoses break on the equipment. All repairs should take place in the loading area or haul <br />road whenever possible.
