4. 0 PROJECT DESCRIPTION 4 . 1 PROJECT LOCATION The El Rancho Rock and Sand, Inc. Quarry is located in San Joaquin County, approximately 10 miles east of Linden, on the east side of Waverly Road one-half mile south of Shelton Road. The Calaveras River flows in a westerly direction about 1 1/2 miles north of the project site. The city of Stockton lies approximately 20 miles to the west-southwest of the project. The outlines of the E1 Rancho Rock and Sand, Inc. property are shown on Figure 1, the Location Map. Assessors Parcel Numbers and Land Use Designations for the E1 Rancho Rock and Sand, Inc. Quarry and adjacent properties are shown on Figure 2 . Access to the site is by way of State Route 26, south along Escalon-Bellota Road, east along Shelton Road, thence south on Waverly Road approximately one-half mile. Site access is illustrated on Figure 3 . 4 . 2 PROJECT OVERVIEW AND OBJECTIVES The El Rancho Rock and Sand, Inc. Quarry operations entail the excavation of near-surface rock and sand deposits from portions of a 480-acre lease holding. The currently permitted area of excavation (EP 81-9) encompasses approximately 67. 1 acres of the northern portion of the "lease holding. The project proponents wish to expand the permitted areas of excavation to include essentially the entire lease holding, through the expansion of the use permit for an existing conditional use. This expansion will allow El Rancho Rock and Sand, Inc. to mine the higher quality reserves in the southern portion of the lease holding. The proposed expansion will necessitate the addition of new equipment and the replacement of some existing equipment to the processing plant, upgrading and widening of haul roads into the southern portion of the site and/or the addition of conveyors from the southern portion of the property to the processing plant. The proposed expansion of the quarry operation into the southern portion of the lease holding will consist of a single-phase 23-year duration excavation operation. A total of 250, 000 tons of material will be excavated in year one of operation, increasing to 500, 000 tons per year by year five. The excavation will ultimately result in a single open pit structure. It is anticipated that excavation operations will be initiated on the westerly side of the quarry site, and will progress eastward. Maximum pit depths on the westerly side will reach 40 feet, while pit depths on the easterly side are not expected to exceed 20 feet. It is estimated that 5.75 x 106 tons of reserves are present on site. 14 CONDOR
