<br />Exhibit G <br />Water Information <br />The site presently has very poor surface drainage, with a slight gradient to the west at approximately 0.5%. <br />An existing irrigation waste ditch, located on the adjacent property to the west of the proposed mining site, <br />intercepts all upgradient surface runoff. Another irrigation waste ditch, located along the north property <br />line, collects runoff from G Road and routes it to a catcfi basin located at the northwest corner of the project <br />site. Surface runoff from within the project site migrates towards 23 Road, but because 23 Road is higher <br />than the proposed project site, the water ponds on the west property line. <br />l) /jthe operation is nor erpected to directly ajject surjace or groundwater systems, a statement ojthat <br />exception shall be submitted: <br />The proposed sand and gravel pit should have little or no impacts to the surface or groundwater system <br />in the area. A Colorado Discharge Permit for sand and grave! production operations, obtained from the <br />Colorado Department of Public Health and Environment Water Quality Control Division, will be <br />obtained, prior to any sand and gravel mining operation, to remove groundwater encountered during <br />the mining operations. <br />2J ljthe operations is expected to directly afj'ect surjace or groundwater system, the Operator shall <br />provide additional information. <br />The sand and gravel mining operation will not affect surface or groundwater systems. The site is <br />hydraulically isolated from surface Flow, and the groundwater at the project site is not suitable for <br />potable use. No adjoining landowners utilize the groundwater. <br />3) The operator shalt provide an estimate ojthe project water requirements including flow rates and <br />annual vol:tmes jot development, mining and reclamation phases ojthe project. <br />During sand and gravel mining operations, the site will need to be dewatered to access all of the sand <br />and gravel. The groundwater collected within the mining areas will be pumped into the Canning <br />Factory Ditch, which is located north of G Road. This ditch is owned and operated by the Grand <br />Junction Drainage District. An approval letter from the Drainage District has been included in Exhibit <br />G. The groundwater will be pumped from the mining operations using pumps with a discharge <br />capacity of azound 4 cubic feet per second, during the mining of the sand and gravel, and for a portion <br />of the backfill placement. On a yearly basis, the applicant estimates it will require 30 days for removal <br />of the sand and graves, and 60 days for backfilling. Therefore, on a yearly basis, the applicant may <br />discharge approximately 227 million gallons of groundwater into the Canning Factor Ditch, which <br />flows into the Colorado River. <br />Water collected within the mining pit will also be used for dust control within the project site. This <br />could amount to as much as 7,000 gallons per day. <br />Water for landscaping along G and 23 Road will requre a drip irrigation system, with the water <br />supplied by an existing domestic water main line located in 23 Road. This landscaping could amount <br />[0 260 gallons per day during the spring, summer and fall months. <br />Reclamation plantings for the site will not require an irrigated water source. Tall Wheatgrass, which <br />will be used for the reclama[ion, will be planted during the spring or fall planting seasons. <br />4) The operator shall indicate the projected amount from each ajthe sources ojwater to supply the <br />project water requirements for mining operation and reclamation <br />
