EXHIBIT G -Water Information <br />1. There is one small wetland area associated with a small tributary stream identified within <br />the proposed area of operation. The wetland area lies along the low areas adjacent to the <br />stream located in the southern portion of the proposed permit azea. Approximately 6 <br />acres in the southernlsoutheast portion of the site will he separated by silt fencing from <br />the active areas of the site and remain undisturbed. Mining of the gravel ridges will <br />avoid this area and will be done at an elevation that will not expose any groundwater. <br />Z. No surface wafer or groundwater will he intercepted or exposed. Sift fences, straw bates <br />and/or berms will be used in active mining areas to contain stormwaters so that they will <br />not affect [he wetland area with sediments or mining activities. Site storm waters will be <br />handled as specified in the Stonmva[er Management Plan (SWMP) required by a CDPHE <br />Stormwa[er Permit which has been filed for the Gray Pit N 2 {a copy of the application is <br />contained in Exhibit M). The groundwater table will not be impacted by this operation. <br />There are no wells in the proposed area or within 200 feet of the proposed area of <br />operations. <br />The proposed permit area has no stock ponds, streams, ditches or reservoirs, (other than <br />the stream/wetland) which receive drainage and/or runoff from storm events. A tributary <br />to Cedar Creek lies to the east of [he proposed permit area between the permit boundary <br />and [he County Road R.O.W. and receives the drainage from the onsite stream and <br />wetland. Access to the site will cross this stream. The USACOE has visited the site and <br />provided their recommendations concerning the crossing and the wetland area. <br />4. Mobile contract crushing operators may supply their own water needs from an offsite <br />sources, however, the applicant/owner has irrigation water available within %. mile of the <br />site for onsite dust abatement and other water needs as long as irrigation allocation needs <br />are met first. Owner/applicant and any contractor project water requirements would be <br />for dust suppression on loading and haul road areas and process areas. An estimated <br />maximum daily volume of 1000 to 3000 gallons would be required for dust control <br />during these activities. If processing, loading and hauling operations take place for 180 <br />days per year then an estimated 360,000 gallons of water may be required. 1[ is more <br />than likely that the actual number of days requiring water for dust suppression during <br />hauling operations will be less than 180 days. <br />5. General Permit Application for Stormwa[er Discharges Associated with Sand and Gravel <br />Production Operations (with associated SWMP) has been applied for the Gray Pit g 2. <br />6. No water rights will be impacted by this operation in compliance with Colorado water <br />laws and regulations. The operation will comply with [he U.S. Army Core of Engineers <br />(COE) regulation by not disturbing the wetland described in 1 above according to <br />conversations with Nick Mezei of the COE. Letter from the COE is attached in Exhibit <br />M. <br />
