• <br />Exhibit G -Water Resources <br />Surface Water <br />Mining is expected to have minimal impact on the prevailing hydrologic <br />balance. No streams or springs exist within the permit area. Runoff is limited to <br />periods of snow melt and summer storms and occurs primarily as overland flow across <br />most of the permit area. On the extreme eastern side of the site, gullies channel runoff <br />from a relatively small portion of the area off site toward the east. Storm water <br />occurring on site will be intercepted by ditches, berms and pond as described below. <br />The entire permit area lies outside any identified FEMA floodplain limits. <br />Irrigation Ditches and Other Structures <br />No irrigation ditches, water impoundments or other structures currently occur on <br />site. <br />Ground Water <br />As noted in Exhibit C, no subsurtace water was encountered during exploration <br />drilling. The operation is thus expected to be dry. <br />Storm Water Control <br />The site lies at the top of a drainage divide. Runoff from the site currently <br />occurs radially in all directions. The operation will begin on the southwest side of the <br />permit area. As the operation progresses toward the north, consecutively more runoff <br />from the top of the hill will be captured and drain toward the southeast. <br />A simple runoff control impoundment will be created on the extreme southeast <br />part of the permit area to intercept storm water from disturbed portions of the site. <br />Small local diversion ditches and or earthen berms will be field engineered as <br />required to route any unconfined surtace flow from disturbed areas to the pond. <br />-13- <br />
