CHRISTIAN PIT <br />EXHIBIT G <br />WATER INFORMATION <br />As has been true in the past, the Christian Pit is not expected to <br />significantly affect surface or ground water. The pits are operated as dry <br />pits. No streams, permanent or intermittent, flow through the area to be <br />affected. After heavy thunderstorms or significant snowmelt episodes, water <br />• does occassionally collect inthe bottom of the pits, but in general it quickly <br />seeps into the ground. <br />In the S.C.S. report of December 8, 1977, reference was made to a "small <br />spring-fed pond" in pit number 2. In part, this is in error. There is such <br />a pond that results from a gentle seep, but it is in pit number 1 and not in <br />pit number 2. <br />This seep was not intentionally created but is indicative of the highly <br />variable water table in the area. Under the gravel beds is a shale Zayer <br />that is far from level. This shale layer more or less corresponds to the <br />water table level and generally occurs about six feet below the pit bottom. <br />Efforts are made to keep the excavations well above any known shale layers <br />• so water can quickly seep into the ground rather than accumulate and create <br />difficult operating conditions. In this Iocation is found a higher water <br />table because of a localized rise in the shale layer. Upon excavation, it <br />created a seep and a small pond. <br />Water needs for the operation are highly variable but average around <br />5000 gallons of water per week. This water is primarily used for watering <br />roads and dust abatement. The water is purchased by agreement from the City <br />of Fountain. <br />Sediment control is achieved in the pits themselves. Little if any water <br />ever leaves the operation area and sediment settles out in the pit bottom. <br />Because this operation is dry and no discharges occur no NPDES permit is <br />needed. <br />• <br />~J <br />n <br />
