KYLE CHRISTIE <br /> PAGE 3 <br /> 3425 N. Tracy Blvd., Tracy ARCO Facility # 2093 <br /> PHS/EHD contact - Harlin Knoll <br /> The start up for the remediation system at this site is scheduled for December 1995. The off- <br /> site delineation is still proceeding pending access from the property owners of the New <br /> Orleans Hotel. Monitoring well ATR#12 is to be abandoned and ATR#6 and ATR#7 will have <br /> new traffic boxes installed. Product is being removed from ATR#8 monthly. <br /> 25775 Patterson Pass Road, Tracy ARCO Facility #6100 <br /> PHS/EHD contact - Margaret Lagorio <br /> A vapor extraction test will be performed sometime next year at this site. After the test a <br /> report defining the extent of the contamination and discussing remedial alternatives will be <br /> submitted. <br /> 501 W. Kettleman Lane, Lodi ARCO Facility #434 <br /> PHS/EHD contact - Margaret Lagorio <br /> The vapor extraction system is currently removing nominal amounts of hydrocarbons from the <br /> subsurface. The groundwater monitoring wells show groundwater to be essentially free of <br /> hydrocarbons. The ultimate regulatory closure of this site was discussed. The need for <br /> confirmation soil sampling to determine the remaining volume of hydrocarbons at the site and <br /> the use of push point technology for this purpose was discussed. Also, subsequent to this <br /> meeting, the possibility of using air data to determine the remaining volume of <br /> hydrocarbons in the soil was discussed among PHS/EHD staff. It may be possible to <br /> determine any potential remaining hydrocarbon mass by using pore volume calculations <br /> or radius of influence measurements and current air data. Under certain site specific <br /> conditions, such as porous soil, this type of data may be acceptable in lieu of <br /> confirmation soil data. <br /> 3212 N. California, Stockton ARCO Facility #2186 <br /> PHS/EHD contact - Steve Sasson <br /> Results of the recent soil boring and monitoring well installation will be submitted in a report <br /> soon. <br /> Summary <br /> The meeting allowed for continued communication between all parties and for continued progress at <br /> the sites. The next meeting to discuss site progress was scheduled for Tuesday January 30, 1996 at <br /> 10:00 a.m. at the office of PHS/EHD. <br /> If you disagree with this summary or have any questions, please contact me at (209) 468-3452. <br /> Donna Heran, REHS, Director <br /> Environmenitl Health Division <br /> lane .
