h. Water for this project will be obtained from the Tierra Piedra River via water <br />rights of the landowners. Water will be used for occasional watering of haul <br />roads and ramp areas. It is estimated that 1000-2000 gallons of water per day <br />may be utilized. <br />i. Groundwater will be encountered while excavating the gravel pit. Excavation <br />will generally be "wet" with backhoe or other method of extracting material from <br />at or below the water level. Minimal dewatering is anticipated, due to expected <br />infiltration capacity of remaining materials. When de-watering becomes <br />necessary, pumps will remove excess water from the pit. This water will be used <br />for irrigation of the adjacent hay field. Due to the flat topography, none of this <br />irrigation water will reach the river as surface flow. <br />j. Use of water will be metered to ensure that landowners comply with water rights <br />of 5 cubic feet of water per second of time. <br />k. No toxic producing materials will be utilized for mining. <br />1. A stable configuration or hydrologic balance will be achieved by a 3:1 average <br />gradient of excavated slopes of the pit faces on all sides. Surface water will <br />infiltrate into the terrace alluvial deposits at the edge of the pit and is presumed to <br />flow into the Piedra River as subsurface flows. Stormwater BMPs will be utilized <br />to prevent any runoff affecting off-site locations. <br />m. The deposit will be processed by a portable screener and a portable crusher as <br />excavations progress from northwest to southeast. Material will be handled by a <br />bulldozer and front-end loader and transported to temporary stockpiles and load <br />trucks. No chemicals will be utilized. <br />n. The primary and secondary commodities to be mined are gravel and sand for road <br />base and fill material. <br />o. Topsoil will be the only incidental commodity generated by the proposed <br />operation. Topsoil will be used for reclamation in the project area and will be <br />utilized at other locations on the property/ranch. <br />p. No explosives will be utilized.
