AZZ <br /> X�SanRCO Meeting Minutes, March 30, 1993 working To Restore Nature <br /> . O Sites (Environmental Consultant; Brown and Caldwell) <br /> Lathrop: SJC requested pre-19$4 data, information on where USTs were <br /> located. Will not accept Hydropunch data for closure. SJC said they have <br /> data showing that the Hydropunch data is not comparable to monitor well <br /> data. ARCO agreed to resample site using method acceptable to SJC. SJC <br /> and ARCO agreed that this is low priority site. <br /> ARCO SS N0. 434, Lodi <br /> SJC skeptical that water is cleaning up. With regard to showing that contamination <br /> in well W-12 is from Shell, need to submit evidence and argument to SJC. RWQCB <br /> showed us copy of Shell 1/93 quarterly report, Shell wells were clean. Reference for <br /> Shell site is Shell Station WIC #204-4416.0202, 420 W. Kettleman Lane. SJC tired <br /> of reading that W-2 is inaccessible. ARCO agreed to explain more in quarterly <br /> report and make another attempt to clean it out. City of Lodi wants to start <br /> pumping from their well, ARCO said they shouldn't until it is determined if shell is <br /> responsible for contamination. <br /> ARCO SS No. 2133, Stockton <br /> SJC wants workplan for installation of vapor extraction wells by May, said air permit <br /> has this deadline. SJC thinks remediation at this site is proceeding too slowly. SJC <br /> thinks that the contamination in well E-3 indicates that plume control is poor, BCC <br /> disagreed - issue not resolved. SJC requested more definition of plume in northwest <br /> portion. SJC said would approve monitoring of fewer interior monitoring wells if put , <br /> new wells in. SJC wants reports to include discussion of hydrologic control, why <br /> Pump rate decreasing. <br /> ARCO SS No. 2093, Tracy <br /> ARCO informed SJC that UST will be replaced within 3 months. BCC/ARCO <br /> presented planned remediation of sparge and vapor extraction. Thayer said she will <br /> Postpone NPDES permit review until ARCO informs her NPDES needed. <br /> cc: Mr. Chris Winsor (ARCO) : <br /> Mr. Chuck Carmel (ARCO) t <br /> Mr. Jay Lucas (Brown and Caldwell) <br /> Ms. Laurie Cotulla (San Joaquin County) '' <br /> Ms. Elizabeth Thayer (CRWQCB) <br /> 9 <br />
