Bradshaw <br /> c/o Jae Anderson <br /> LFR Levine Fricke <br /> 1900 Powell Street, 12' Floor <br /> Emeryville, CA 94608-1827 <br /> DRAFT OPERATIONS AND MAINTENANCE MANUAL,PHASE I INTERIM REMEDIAL <br /> ACTION,LINCOLN VILLAGE CENTER,STOCKTON, SAN JOA QUIN COUNTY <br /> I have reviewed the 12 February 1999 Draft Operations and Maintenance Manual, Phase IInterim <br /> Remedial Action, Groundwater Extraction and Treatment System, Lincoln Center, Stockton, California <br /> (Draft O&M Manual) submitted by LFR Levine Fricke(LFR) for the Settling Dry Cleaning Defendants. <br /> I have the following comments: <br /> 1. On Page 2,the Draft O&M Manual states that the Waste Discharge Requirements (WDRs) were <br /> issued by the Board on 23 April 1998. The Board adopted the WDRs on 17 April 1998. <br /> 2, On Page 13, LFR discusses the changeout procedures for the liquid-phase granular activated carbon. <br /> The manual needs to clarify the rotation and replacement procedures for the GAC canisters. <br /> Additionally, LFR proposes to replace the lead GAC canister when effluent concentrations of <br /> Hazardous Substances from the lead canister are above the WDR limits for two consecutive, <br /> monthly sampling periods. The Final O&M Manual should provide a discussion regarding the <br /> loading rates on the trail canister after the lead canister has breakthrough. <br /> 3. Table 5 needs to be revised to reflect the treatment system effluent limits for monitored chemicals. <br /> We hereby accept the O&M Manual on the condition that the above comments are addressed. Please <br /> submit the Final O&M Manual to the Board by 12 April 1999. If you have any questions,you may <br /> contact me at (916) 255-3077. <br /> * LLO <br /> tengineering Geol ist <br /> cc: San Joaquin County Environmental Health, Stockton <br /> Mr. Robert Thomson, Esq., LeBoeuf, Lamb, Greene & MacRae <br /> Mr. Phil Johnson, Vice President, Sims Grupe Management <br /> Ms. Anne Farr, Ph.D., Farr Associates <br /> California Environmental Protection Agency <br /> ea Recycled Paper <br />
