C WASTE DISCHARGE REQUIREMENTS FOR CITY OF STOCKTON AUSTIN ROAD LANDFILL FACILITY CLASS III LANDFILL SAN JOAQUIN COUNTY from the extracted water and the treated water is discharged to the north branch of the south fork of Littlejohn Creek. This discharge is regulated under separate Waste Discharge Requirements and NPDES permit. -5- 29. The City of Stockton has adopted a final environmental impact report (EIR) on the project in accordance with the provisions of the California Environmental Quality Act (Public Resources Code Section 21000, et seq.), and Title 14, CCR, Section 15301. The project may have the following significant impacts on water quality: a. Ground water contamination would result from a failure of the liner and leachate collection system. b. Surface and/or ground water contamination could result if differential settlement damaged the liner and/or the leachate collection system. 30. The Board has reviewed the EIR and these WDRs will mitigate or avoid the significant impacts on water quality as follows: a. Ground water extraction wells developed as part of the Corrective Action Program will be monitored and maintained to extract any residual contamination by leachate. b. Hazardous materials spotted during the required load checking program will be removed from the waste stream reducing the hazard from leachate should there be a leak from the leachate collection system. c. The project includes a leak detection system, a series of secondary collection trenches beneath the liner and directly under the leachate collection trenches. 31. On 9 October 1991, the United States Environmental Protection Agency (USEPA) promulgated regulation (Title 40, Code of Federal Regulations, Parts 257 and 258, "federal MSW regulation" or "Subtitle D") that apply, in California, to dischargers who own or operate Class H or Class III landfill units at which municipal solid waste (MSWLF) is discharged.
