In addition, <br />their requirements for a "safe bum" area. <br />when they are available. <br />SACRAMENTO AV— <br />Q017/018 <br />Kleinfelder has sent a letter to the District requesting <br />We will forward responses of the District to PHS <br />"PDM Section B -6d corresponding to PSR section D.6. Regarding litter the PSR states that <br />latter should not normally be a problem. Section 17711 Article 7 Chapter 3 Title 14 of <br />California Administrative Code states "Litter and loose materials shall be routinely collected <br />and disposed of properly, " EHD requires a statement that the landfill will comply with section <br />17711. " <br />Litter <br />Cove Contractors will routinely collect and properly dispose of litter, pursuant to Section <br />17711. <br />Comment on Section C-2• <br />"PDM Section C-2 corresponding to PSR Section E.3. The PSR states "It is not feasible to <br />install leachate monitoring devices for the site due to proximity of waste to groundwater. <br />Section 17704 Article 7 chapter 3 77tle 14 of the California Aministrative Code which states <br />"The operator shall take adequate steps to monitor, collect, treat and effectively dispose of <br />leachates. " EHD feels that the proximity of the waste to groundwater makes the installation of <br />a leachate collection system imperative." <br />Leachate Management <br />The landfill contains waste from past operations which is on close proximity to or may have <br />contacted ground water. Effects on ground water from years of this condition have been <br />minimal in consideration of local ground water quality and the hydrogeologic conditions at the <br />site. The RWQCB is in receipt of ground water monitoring reports from the site and <br />conditions were evaluated in the SWAT for the landfill (dated September 1988). <br />Installation of an LCRS for existing waste is not feasible. Installation of a liner and LCRS for <br />continued disposal of treated ASW and inert waste may not be warranted based on the limited <br />potential effects of the disposal as described in Designated Level Assessment (Section 2.5) and <br />the Corrective Action Evaluation (Section 10) of the RWD which is Appendix D to the PSR. <br />Sections F.1 and F.2 of the PSR discuss potential effects of the existing and future ASW on <br />ground water. As indicated in the PSR, capping of the site is recommended by Kleinfelder to <br />limit effect to ground water from the existing waste and future ASW. Modelling performed <br />indicated that capping (cap assumed to limit infiltration to 10%) within 5 years will effectively <br />stop contaminant migration through the vadose zone. This is well within the ten year period <br />for which it is estimated that uncovered waste disposal activities potentially would increase <br />TDS by only 100 mg/1. <br />JM -91-4 Page 6 of 7 <br />Copyright 1991 Kleinfelder.
