EXHIBIT G -Water Information <br />There are four small seepage areas identified within the proposed area of operation. The <br />seep areas lie in the low azeas between gravel ridges and aze likely associated with <br />'vrigation waters from Bostwick Park. Mining of the gravel ridges will avoid these seep <br />areas and will be done at an elevation that wilt 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 # 1 # M-2003-092. The groundwater table will not be <br />impacted by this operation. There are no wells in the proposed area or within 200 fee[ of <br />the proposed area of operations. <br />4. 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. Hard Rock Redi-Mix, Inc. and/or other mobile contract crushing operators may supply <br />their own water needs from an offsite sources, however, the applicanUowner has <br />irrigation water available within'/. mile of the site for onsite dust abatement and other <br />water needs as long as irrigation allocation needs are met first. Owner/applicant and <br />Hard Rock Redi-Mix, Inc. project water requirements would be for dust suppression on <br />loading and haul road areas and process areas. An estimated maximum daily volume of <br />1000 to 3000 gallons would be required for dust control during these activities. If <br />processing, loading and hauling operations take place for 1 SO days per year then an <br />estimated 360,000 gallons of water may be required. It is more than likely that the actual <br />number of days requiring water for dust suppression during hauling operations will be <br />less than lS0 days. <br />4. General Permit Application for Stormwater Discharges Associated with Sand and Gmvel <br />Production Operations (with associated S WMP) has been issued for [he Gray Pit # 1 <br />(COG-501259) and will apply to the revised Gray Pit # I. <br />5. 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 1 above according to <br />conversations with Nick Mezei of the COE. Letter from the COE is attached in Exhibit <br />N. <br />b. South of the affected area is a creek that carries spring water to the irrigation pond below <br />the west end of the permit area. Ditches carry water from this pond to irrigate hay <br />fields in the valley below. A normally dry irrigation diversion ditch lies to the north <br />outside the proposed permit extension area. The applicant owns the springs, pond, ditches <br />and hay fields. <br />
