areas as wildlife habitat. Any available topsoil will be salvaged and stockpiled on the west side <br />stockpile area to place on the disturbed areas and slopes after gmvel extraction and final grading. <br />Mining will be done with dozers, front end loaders and excavators. Gravel and cobble deposits <br />will be facially removed from the ridges for loading, hauling and processing. Gravel will be <br />loaded on dump trucks with rubber tired loaders and hauled offsite or temporally stockpiled for <br />later hauling. A crusher/screen set up may be onsite periodically to process material for hauling <br />and/or project stockpiles. An asphalt plan[ may be onsite occasionally if the operator secures <br />contracts for asphalt production. The crusher/screen spread and asphalt plants are not permanently <br />installed at the site and anticipated operations would be from 4 to 12 weeks at a time on an as <br />needed basis. Following the extraction of all aggregate material, the site will be graded to a <br />uniform slope from north to south and covered with the stockpiled topsoil. The slope will then be <br />re-vegetated with the Soil Conservation Service's recommended grass and shrubs to a final use as <br />rangeland. <br />(b) Earthmoving; <br />All topsoil material will be stripped and stockpiled using bulldozers, motorgraders and <br />front-end loaders. All mined materials will be excavated and handled onsite using <br />bulldozers and front-end loaders to feed the crusher/screening equipment spread and to <br />temporarily stockpile processed materials. Front-end loaders will be used to load haul <br />trucks. <br />(c) Water diversions and impoundments; <br />There are four small seepage areas identified within the proposed area of operation. The <br />seep aeeas lie in the low areas between gravel ridges and are likely associated with <br />irrigation waters from Bostwick Park. Mining of the gravel ridges will avoid these seep <br />areas and will be done at an elevation that will not expose groundwater that may be <br />associated with them. No surface water or groundwater will be intercepted or exposed. <br />Silt fences, straw bales and/or berms will be erected around these seeps so that they will <br />not be affected buy sediments or mining activities. Site storm waters will be handled as <br />specified in the Stormwater Management Plan (SWMP) under the current CDPHE Permit <br />#COG-501259 for the Gray Pit #I # M-2003-092. The SWMP and CHPHE permit will <br />include all original and extension areas at the site to the total of 23.75 acres. The <br />groundwater table will not be impacted by this operation. There are no wells in the <br />proposed area or within 200 fee[ of the proposed area of operations. <br />2. The proposed permit area has no stock ponds, streams, ditches or reservoirs, (other than <br />the seeps) which receive drainage and/or runoff from storm events. An irrigation pond <br />adjacent to the south of the proposed permit area collects irrigation seepage, and spring <br />and runoff waters from the upgrade areas below Bostwick Park. <br />3. No water rights will be impacted by this operation in compliance with Colorado water <br />laws and regulations. The operation will comply with the U.S. Army Core of Engineers <br />(COE) regulation by not disturbing the seeps described in (above. <br />4. South of the affected area is a normally dry creek that carries spring water to the <br />irrigation pond below the west end of the permit area. Ditches carry water from this pond <br />to irrigate hay fields in the valley below. A normally dry diversion ditch lies outside the <br />northern permit boundary. The applicant owns the springs, pond, ditches and hay fields. <br />
