Box 1810 Stockton, CA 95201 CLOSURE OFMODULELF-1, EVALUATIONMONITORING PROGRAM,AND MODULE 1 DEMONSTRATION OF MEETING LINER PERFORMANCE STANDARDS, FOOTHILL SANITAR Y LANDFILL, GALA VERAS CO UNTY(Case No. 1928) We have reviewed the compliance record for the Foothill Sanitary Landfill regulated by Waste Discharge Requirements (WDRs) Order No. 94-258 and applicable laws, regulations,plans, and policies of the Regional Board. Our review included documentation regarding the Evaluation Monitoring Program and the newly submitted Liner Performance Demonstration for Module 1 and Future Modules at the Foothill Sanitary Landfill(Report), dated 4 June 2002, as prepared by EMCON/OWT, Inc. Based on our review, there are tasks that must be finalized in order to comply with the minimum standards of Title 27, California Code of Regulations, Division 2, Subdivision 1 (Title 27). Closure of Module LF-1 The Foothill Sanitary Landfill (FSL) currently has one unlined Module LF-1. Groundwater monitoring wells have detected Volatile Organic Compounds (VOCs) and possibly minerals and metals above background concentrations. The Board's letter of 29 January 2001 states the following: "Waste Discharge Requirements Order No. 94-258 lists general plans for the expansion to the new units and closure of the existing unit. Additionally,the revised"Preliminary Closure and Post-Closure Maintenance Plan"(dated May 1994)indicates general plans for the expansion and for the closure of the existing unit...The county has submitted an Evaluation Monitoring Plan for a Volatile Organic Compound release to groundwater and suspects that landfill gas may be contributing to the VOC release. It is appropriate at this time to prepare a schedule for final cover and closure of the existing unit(1), as well as a final closure plan with the cost details for unit I. The Final Closure plan may need to refer to corrective action for the existing unit. Closure and supporting documentation shall comply, at a minimum,with the California Code of Regulations(CCR),Title 27 ... as indicated in the May 1994 Preliminary Closure Plan....Please respond to this letter in writing by 16 February 2001..." The County's letter of response, dated 6 February 2001, states, "The development of a new waste management module and subsequent closure of the current area of fill is currently slated for 2003."
