r_•rl^�.D �PSN �C- vIseo RECLAMATION PLAN RecE;•'er't�rl� Applicant, George Reed, Inc., is requesting a permit for the removal of approximately 2 million tons of rock, sand, and gravel over a 12 year period, which includes total reclamation, using the open pit method of extraction with reclamation concurrent with excavation. George Reed, Inc. is currently extracting sand and gravel from an existing quarry to the south issued a permit in 1990, QX-90-1. The permitted quarry is expected to be depleted in year 2000. This permit would allow applicant to continue operations on contiguous parcels adjacent to the existing quarry without substantial change in the daily operations as they currently exist. All extracted materials will be processed at the existing plant located on the Northside of the Mokelumne River. I. DESCRIPTION OF ENVIRONMENTAL SETTING: The project site is bounded to the North by the Mokelumne River and County Park, East by a bluff, South by the existing quarry operation and West by farm land. All land currently being farmed within the project area will continue to be fanned until excavation commences. A. MAPS: Maps showing project area, site access and topography attached. B. GEOLOGY: The project site lies in a valley which is within the ancient flood plain of the Mokelumne River and is bounded on the east and south by a high natural bluff, which rises steeply about 35 feet. The Mokelumne River lies to the north and the valley slopes away gently to the west. The alluvial deposits of soil, sand, gravel and rock, which form the valley floor, are of recent quaternary origin and of variable depth and thickness. The silts, sandy silts, and fine sands usually occur at or near the surface and vary in depth from 0 to 15 feet. Agricultural releveling has significantly altered(surface materials). Below these silts and fine sands are the coarser sands and fine and coarse gravels, and finally the larger cobble type rocks. These materials are roughly sorted into strata of varying depths. Below the lower limits of the alluvial deposits is a densely compacted grayish colored lava ash of undetermined thickness, believed to be from the lower or middle Pliocene era. The area has no history of earthquakes, landslides, subsidence or other geologic instability. The project site is classified as a Mineral Resource Zone-3 by the Division of Mines and Geology, in accordance with the California Surface Mining and Reclamation Act of 1975, which indicates that the site contains potentially significant deposits of aggregate resources. C. HYDROLOGY: During the January of 1997 excessive rains and flooding along the Central Valley's rivers, none of the parcels within the project area were inundated or subjected to over flow from the South bank of the Mokelumne River. The project area is located outside the 100 and 500 year floodzone. Excavation will not penetrate groundwater so there should not be any impacts on groundwater quality or quantity. Based on borings, the ground water elevation is approximately 60' +/-. Excavation depths will not exceed 30' +/-. Waste discharge is not applicable to this application.
