This Order was issued by the California Regional Water Quality Control <br /> Board, Central Valley Region, on January 29, 2010. <br /> The NCRC&SL is located at 17720 East Harney Lane, approximately nine miles east of Lodi (Figure 1). <br /> Land uses within 1,000 feet of the facility are primarily agricultural and livestock grazing. The average <br /> precipitation near the landfill is 17.5 inches per year. <br /> The NCRC&SL is a single solid waste management unit, designated Class III, accepting non-hazardous <br /> municipal solid waste and inert waste, as defined in §20164 of Title 27. The site is 185 acres in area, <br /> comprised of lined areas (previously designated"modules"), each constructed on an as-needed basis. <br /> The total capacity of the landfill is 16.2 million cubic yards. The landfill is expected to close no sooner <br /> than 2032,based on current disposal rates and current capacity. The current active fill area is Area 4 <br /> (Figure 2), with monthly of waste discharge as follows: <br /> TABLE1 <br /> Second Semester 2012 Monthly Refuse Disposal <br /> ® North County Recycling Center And Sanitary <br /> Landfill <br /> MONTH REFUSE DISPOSAL <br /> (TONS) <br /> July 11,488.3 <br /> August 12,544.4 <br /> September 10,061.1 <br /> October 12,357.8 <br /> November 11,631.6 <br /> December 13175.5 <br /> Geology <br /> The sediments underlying the Unit consist of inter-bedded sands, silts and clays with occasional gravelly <br /> layers.

Groundwater elevations <br /> range from-30 feet-42 National Geodetic Vertical Datum (NGVD), fluctuating seasonally <br /> ® approximately 6 feet. The groundwater is unconfined. <br /> North County RC&SL Public Works/Solid Waste <br /> 2nd Semester and Annual 2012 Groundwater Monitoring 1 County of San Joaquin—January 15,2013 <br />
