<br /> <br />-9- <br />• No well or springs have been identified in McClane or Munger Canyons. No <br />groundwater rights have been adjudicated within a three mile radius of the <br />mines. Neither operation will have an effect on any major aquifers during the <br />1 ife of the mine. <br />Drilling in and around the McClane and Munger permit areas indicates that the <br />mine zone will be dry. No groundwater inflows are anticipated for either <br />operation. There will be no need for discharge of mine water from either mine <br />during the life of the mine. <br />A saturated zone has been identified in the Cameo coal seam, but only in the <br />Munger Canyon mine workings in the eleventh year of operation. Groundwater <br />inflows into this mine will be monitored throughout the term of operation so <br />that the zone can be identified further and impacts can be projected. <br />The mine workings will approach the Cameo subcrop in East Salt Creek in years <br />eleven through fifteen of the Munger Canyon Mine operation. No effect on the <br />East Salt Creek tributary groundwater is anticipated. Additional groundwater <br />monitoring data will become available during the 5 year permit term, and the <br />data will be included in the next 5 year permit application. If the data <br />indicates a real or potential adverse impact on the aquifer, appropriate <br />corrective actions will be taken by CMLRD and OSM through new permit <br />requirements and stipulations, if necessary. <br />The effects of underground mine workings in Stove and Bumiger Canyons on the <br />• quality and quantity of surface water in Big Salt Wash is expected to be <br />negligible. <br />There is a potential for' surface water infiltration into the mine workings via <br />natural and mine induced fractures. This potential is very low due to the low <br />precipitation experienced by the region and because of the steep slo?es over <br />the mine workings. <br />The coal zone to be mined has been shown to contain relatively little ground <br />water. Also, no springs have been identified in the area of Stove and Buniger <br />Canyons. No aquifers or regional extent will be impacted by the operation. <br />There will be no cumulative impact on ground water in the Big Salt Wash <br />drainage as a result of the combined impact of the Munger Canyon and <br />Dorchester Fruita operations. These mines are essentially hydrologically <br />isolated from each other and by the intervening recharge zone in Big Salt <br />Wash, resulting in little if any impact on the hydrologic systems. <br /> <br />
