PC: 9-6-90 QX-90-1 RECLAMATION: As previously described, overburden removed and stockpiled would be replaced, and the site would be recontoured for agricultural use. The final elevation- of the proposeed quarry site and the quarry area adjacent to the processing facility would be about 12 feet and 13 feet lower than the existing elevations , respectively . The applicant is proposing that an approximately ten-acre area in the southeastern corner of the proposed quarry area south of the river be used for construction of a drainage impoundment to capture storm runoff from the excavation area during periods of unusually heavy rain. This area is adjacent of a smaller drainage pond that accepts runoff from the surrounding agricultural area and overflow from another pond that captures runoff from Clements . The pond area would be graded to an elevation about four feet lower than the surrounding fields . The applicant has proposed that the ten-acre area be deeded to the County and be made available for recreational purposes . Upon completion of mineral extraction activities, the entire processing facility would be dismantled and removed from the site. Any economically viable sand and gravel which is beneath the processing facility and stockpile areas would be excavated. The applicant estimates that this area may contain a two- to three-year supply of sand, with some gravel. This material would be processed into aggregate products using either a portable processing facility at the site or by transporting the material to an established off- site facility. The latter would take place only after an approved permit is secured from the County. The area north of the existing processing facility would be used as a borrow area during reclamation of the processing facility and settling pond areas near the plant. The elevation of the borrow area would be lowered and contoured to allow agricultural uses. A portion of the quarry area adjacent to the processing facility will be reclaimed for agricultural purposes, with a portion along the river being used to increase the size of the riparian corridor along the north bank of the river. The paved access road to the existing processing facility would remain in place to provide access to the reclaimed areas. The area currently occupied by the processing facility would be returned to agricultural production; however, specific crops that would be established in this area have not yet been determined. The riparian corridor along the north bank of the Mokelumne River would be preserved. -25-
