The report <br /> was submitted in accordance with Waste Discharge Requirements Order 5-01-176. New WDRs <br /> were adopted for the Corral Hollow Landfill 1 February 2013 Board meeting and thus, <br /> subsequent reports shall reflect reporting requirements defined in those WDRs. <br /> Groundwater samples collected from five site monitoring wells continue to report detections of <br /> volatile organic compounds (VOCs) due to a release from the waste management unit. The <br /> source of the release has been interpreted by the Discharger as landfill gas (LFG). LFG is <br /> detected in the vadose zone and groundwater, which is a violation of Title 27 and the WDRs. <br /> Board staff are addressing this continued release through preparation of a Cease and Desist <br /> Order. <br /> The Monitoring and Reporting Checklist is attached for your information. <br /> If you have any questions please call Todd Del Frate at 916-464-4737. <br /> ` 1 <br /> WENDY WYELS, Supervisor <br /> Compliance and Enforcement Section <br /> cc: Gino Yetka, CalRecycle, Sacramento, CA <br /> Robert McClellum, San Joaquin County Environmental Health <br /> John Hower, Geologic Associates, San Diego, CA <br /> CIWQS VID#943159 <br /> KARL E.
