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