b <br /> s <br /> INFORMATION SHEET <br /> SAN JOAQUIN COUNTY <br /> HARNEY LANE LANDFILL <br /> CLASS III LANDFILL <br /> Harney Lane Landfill is in San Joaquin County approximately 1/4 mile east of Jack Tone Road. <br /> The 127-acre facility is owned and operated by the San Joaquin County Department of Public <br /> Works. <br /> The landfill was previously regulated by Waste Discharge Requirements (WDRs) Order <br /> No. 93-093. The facility ceased waste acceptance on 1 November 1991, which is prior to the <br /> 9 October 1993 date on which most RCRA Subtitle D requirements went into effect. Only the <br /> RCRA Subtitle D final cover requirements are applicable to this site. However, Chapter 15 cover <br /> requirements are more stringent than RCRA Subtitle D, and therefore the final cover must meet <br /> Chapter 15 requirements. <br /> The Discharger submitted a final closure plan, dated 31 January 1992 and a revised plan in January <br /> 1994. The final cover was applied in September and October 1994 and consists of a minimum <br /> two-foot foundation layer overlain by a one-foot thick clay barrier layer and a one-foot thick <br /> vegetative layer. A Final Documentation Report for the final cover was submitted in January 1995 <br /> and was approved by Board staff on 31 January 1995. These revised WDRs cover the closure and <br /> post closure maintenance period of the site. <br /> Landfill operations have used 112-acres at the site, with 15-acres being set aside for a migrant farm <br /> labor housing project. Land within 1000 feet of the facility is used for agriculture, with the <br /> exception of the farm labor housing at the northwest comer of the landfill property. Ground and <br /> surface waters around the site are used for irrigation, recreation, esthetic enjoyment, navigation, <br /> and preservation of aquatic life and other resources. <br /> Ground water is approximately 110 feet below ground surface. The soils underlying the landfill <br /> consist of unconsolidated silts, clays, and sands. Surface water drainage is to South Paddy Creek <br /> which is tributary to Bear Creek and Disappointment Slough which flows into the San Joaquin <br /> River. <br /> GAI <br /> Rev. 10 January 1996 <br />
