Munn&Perkins Quarry Excavation Permit The project site is located on the south side of East River Road approximately 1,000 feet west of Harold Avenue in southeastern San Joaquin County approximately 2 miles southeast of the City of Escalon(see Figure 2-1).The Stanislaus River and Stanislaus County line is located within a few hundred feet of the southwest border of the project site.State Route(SR) 120 is located approximately 2 'h miles north of the project site and SR 99 is located approximately 12 miles to the west. 2.3 Existing Operations The existing 142 acre Munn&Perkins Quarry has been producing construction aggregate onsite since 1957.An approved Quarry Excavation Permit was adopted for the site in 1989 and was extended by the County on March 4, 1999 allowing for the extraction of approximately 3 million tons of aggregate material and processing of import material over a 30 year period extending until the year 2029. The existing site consists of reclaimed areas, reserve areas, wash ponds, production facilities, administrative offices, and access roads. The reclaimed and reserve areas are mostly planted in orchards. These orchards are farmed by independent contractors.Production facilities include screening and crushing equipment, an asphalt concrete hot mix batch plant("AC plant"),two storage silos for asphalt concrete,and a scale house. The Main access to the site is by way of a private driveway off E. River Road. Existing activities consist of processing of aggregate materials(sand and gravel).Aggregate is trucked to the site from source pits,washed, screened and crushed.Additional sand is excavated from the quarry located northeast of the project site and transported via conveyer belts underneath E. River Road to the processing facilities. The processed aggregate is either directly hauled to the construction site, or is used for the onsite AC plant. AC production is limited to 5,200 tons/day and 896,350 tons/year by permits issued by the San a Joaquin Valley Air Pollution Control District. The plant can produce up to 325 tons/hour(which would equal 16 hours of continuous operation before reaching the maximum permitted daily limit). The storage silos can hold 250 tons each of asphalt concrete, for a total storage capacity of 500 tons. 2.4 General Plan and Zoning Designations The project site consists of a single 142-acre parcel zoned AG-40(40 acre minimum),with a General Plan Designation of General Agriculture(AG):The General Agriculture Designation was established to preserve agricultural lands for the continuation of commercial agricultural enterprises. Surface mining operations are permitted within the AG-40 zone under Title 9 of the Development Title of San Joaquin County(9-600)with an approved Quarry Excavation Permit.As described in Section 2.3, a permit was issued in 1989 and amended in 1999. The proposed project would revise the existing permit. Munn&Perkins Quarry Excavation Permit 2-2 ESA 1211086 Draft EIR April 2011
