Page 6 of 6 Review (10/89), RDSI (3/90), Draft Permit (10/91)) this site has not been issued WDRs. ` RWQCB staff verbally indicated (11/15/91) that WDRs may be issued by 2/92. ) 14 CCR 17616- RDSI The 8/77 RDSI has been updated and amended several times (11/88, 9/89, 3/90) . As noted under PRC 44014(b) above, the RDSI must be updated to reflect all current operations at the site (operating hours, tonnage, acreage, etc. ) and to thoroughly and completely address each section (a-1) of CCR 18222. A thorough description of the City's (Public Works Department) use of the landfill for the storage/stockpiling of asphalt and concrete (rip- rap) must also be included in the RDSI. The use of the landfill for the temporary storage of dirt from a construction project needs to be addressed. 14 CCR 17710- Grading of Fill Surfaces Several areas of depression and subsidence were observed (see attached map) providing areas for ponding of storm water. The methods of stockpiling cover (southwest of the current active face) and rip-rap (see attached map) do not provide for the lateral run-off of water. Of particular concern is a groundwater monitoring well located in a depression in _ the southwest portion of the landfill along French Camp Slough. (Noises P. Giambastiani of Gambi Enterprises provided an agenda from a "Landfill Operation Meeting" (10/14/91) where "Projects to Accomplish" concerning slope grading were identified and discussed. Mr. Giambastiani indicated that a grading plan would be developed and implemented in the near future. ) 14 CCR 17682- Cover On the day of the inspection it was observed that adequate cover had been placed on the uppermost surface of the previous day's waste but had not been placed over the most forward reaches of the active face. This standard requires daily cover, compacted to a minimum thickness of six inches, to be placed over all surfaces of waste for sites receiving over 50 tpd. 14 CCR 17684- Intermediate Cover Some exposed waste was observed in areas of intermediate cover (see attached map). 14 CCR 17704- Leachate Control Possible ground-water contamination was reported in the "Verification Monitoring Program and Report of Waste Discharge, French Camp Landfill, 6/29/90." The RWQCB provided comments to this report on 8/28/90 and requested the operator to respond by 9/17/90 so that WDRs, including a Monitoring and Reporting Program, for the facility could be drafted. The 3/90 RDSI states, "the sloughs on three sides of the site generally provide for containment and control of leachate." Board staff requests clarification on this "containment and control" method. 14 CCR 17709- Contact with Water The 3/90 RDSI reports that "refuse was encountered in Boring MW-1 to a depth of 37 feet, which is approximately 4 feet below first-encountered ground water. This indicates that ground water is in contact with the refuse and a portion of the landfill." The remediation of this violation needs to be addressed by the RWQCB in the forthcoming WDRs. 14 CCR 17777- Final Site Face This standard.-requires that the slope of those portions of the fill which will be the final exterior surface shall not be steeper than approximately 300. Using a clinometer, slopes of greater than 30° were found along both the French Camp and Walker sloughs (see attached map) . Waste Management Special
