0 0 <br /> Subject: RE: Pilkington Facility, Lathrop, CA <br /> Dana -this is the what CalRecycle has recommended to the LEA for additional investigation requirements: <br /> Historical Aerial Photographs for the site from 1960-1990. <br /> Request for information from Pilkington North America or Libby-Owens-Ford for all files/reports/correspondence <br /> related to the disposal site <br /> Geophysical Survey based on the results of reviewing historical aerial photographs and determining the maximum <br /> extent of operation (including the Power Plant property) <br /> Prepare a scaled topographic map (in AutoCAD or other engineering program)that depicts the disposal area <br /> boundary(1 inch = 100 feet) <br /> Conduct a trenching investigation based on the geophysical survey boundary-collect data on horizontal and <br /> vertical extent of waste,cover conditions and waste characteristics <br /> Collect 20-30 samples from the disposal area and analyze for CAM 17 Metals(TTLC&STLC), Semivolatiles(8270), <br /> PCBs, PAHs, Dioxins and Furans <br /> Install an LFG monitoring network in accordance with 27 CCR 20925 and implement an LFG monitoring program <br /> Annotate the results of field testing on the topographic drawing to include: waste limits(boundary),trenching& <br /> boring sample locations, LFG monitoring wells and analytical testing results. <br /> The field data should be placed into a final investigation report that provides: <br /> -Topographic drawing/map of the site (with waste boundaries and sample locations),-Analytical testing results-Boring <br /> and trench logs-Landfill cross-sections-A volume estimate of waste in place and waste classification for disposal and <br /> cost estimate for clean-closure; -A cost estimate to consolidate and cover the disposal site for long-term maintenance <br /> and monitoring. <br /> -Discuss LEA/CalRecycle requirements for long-term inspections, maintenance and monitoring and notification of <br /> property transfer and approval of post closure land-use development <br /> Please see attached CalRecycle "Former Landfill and Disposal Site Investigations"guidance document(located at: <br /> http://www.caIrecycle.ca.gov/Publications/Documents/1359%5C20100080.pdf) <br /> Are the above requirements included in the proposed work scope? <br /> Glenn <br /> P.S. I am available to discuss this week. CalRecycle and the LEA are OK with RWQCB Lead Oversight-the primary goal <br /> of CalRecycle regulations is to ensure that the disposal site is defined and covered to prevent public contact and that <br /> grading,drainage and erosion control measures are implemented to protect the cover. Also LFG testing should be <br /> conducted to ensure that landfill gas will not impact building structures or adjacent properties. Finally institutional <br /> controls such as deed restrictions may be necessary to maintain the integrity of the cover system and monitoring <br /> networks. <br /> -----Original Message----- <br /> From: Dana Parry [mailto:danap@reynoldsandbrown.com] <br /> Sent: Monday,lune 22, 2015 2:53 PM <br /> To: Gerald.Djuth@waterboards.ca.gov <br /> Cc: Palmer,Ann@Waterboards;Ambrose,Sabra@CalRecycle; William Little (wlittle@advgeoenv.com); Robert McClellon <br /> [EH] (RMcClellon@sjcehd.com);Young, Glenn @CalRecycle; Robert Marty<rmarty@advgeoenv.com> <br /> (rmarty@advgeoenv.com) <br /> Subject: RE: Pilkington Facility, Lathrop,CA <br /> 2 <br />
