Exhibit C-2 <br /> Stormwater Management Plan and <br /> Spill Prevention Control and Countermeasure Plan <br /> I. Best Management Practices during Mining Activities (Stormwater): <br /> • The Existing Access Road is already covered with gravel to minimize erosion. <br /> • Applicant will place overburden and product stockpiles along the east and south edge <br /> of all the mining phases as a first step of mining operations, the berms and pits <br /> created will control erosion and sedimentation. The operator is committed to control <br /> (prevent) erosion and sedimentation from reaching any drainage. All methods of <br /> control will be used, sediment traps, riprap, straw bales, earthen berms and liners. <br /> • Stormwater runoff from disturbed areas will drain into the pit floor and be directed to <br /> the south and east side of the permit area. Here a small berm will be constructed <br /> along the south and east corner of the permit area which will intercept overland flows. <br /> These flows will then be allowed to seep through the porous berm and off-site within <br /> 72 hours. <br /> • The pit floor will be graded as extraction occurs at a 1-2% slope in order to direct <br /> runoff into the containment berm at the southeastern end of the Site. This berm will <br /> be constructed with a coarse material in the low end to allow for filtration of any <br /> stormwater that reports to this area. <br /> • Stockpiled topsoil and overburden will be seeded with the seed mix identified in <br /> Exhibit C, section(b) in order to stabilize the stockpiles. <br /> • Where there is a potential for storm water to erode material off of the site, sediment <br /> control measures will be installed that could include a combination of berms, silt <br /> fence, or erosion control logs. <br /> 11. Best Manayement-Practices for urinal Site Reclamation(see Exhibit D for detailed <br /> reclamation process): <br /> • All disturbed areas will be reseeded with the seed mixture identified in Exhibit D, <br /> section 1(c). <br /> • Site grading will be developed so that concentrated drainage that could result in scour <br /> does not occur. <br /> III. Spill Prevention Control and Countermeasure Plan <br /> • Bulk storage of fuel, and small amounts of lubricates, will be stored on site in an <br /> earthen berm with an approved liner around and below the storage container. The <br /> earthen structure will have a capacity of at least 110% of the tanks and containers <br /> tanks. This type of structure will be leak resistant and readily cleanable if a spill does <br /> happen. The liner will form a pool that the liquid cannot escape to the surrounding <br /> areas. The other features of this structure is that it will be designed in such a way that <br /> it will be easy to clean up any possible spills. All spills will be soaked up with an <br /> absorbent material such as sand or other substances that can absorb the spilled oils or <br /> Burton Farms LLLP Pagel of 2 <br /> Construction Materials Limited Impact(I 10(c))Operation Reclamation Permit Application Form <br />
