The <br /> site address is 23577 Mountain House Parkway, Tracy, a -170 acres parcel. <br /> An assessment regarding to this spill was conducted by Kleinfelder on May, 2004. The <br /> assessment indicates there was ground water contamination (for example: 0.8 ug/l of <br /> benzene) . <br /> A work plan / scope of work prepared by Kelinfelder was submitted to EHD for comment on <br /> September, 2004. This office has prepared a response letter dated September 23, 2004 (A <br /> copy is attached) . <br /> Trying to make story short, there will be some contamination be left on site according to <br /> the work plan. Therefore, it is EHD's recommendation for the RP to obtain signo£f from <br /> DTSC and RWQCB. <br /> I hope these information will be a start point. Did Geocon Consultant a representative <br /> for RP? I did not deal with them on this project yet. <br /> If I could be any assistance, please feel free to contact me. <br /> Steven C.

I work in the Central Valley Regional Water <br /> Quality Control Board's Site Cleanup Section. Geocon Consultants called asking what the <br /> Regional Board's involvement is or will be with the Chevron Pipeline site near Mountain <br /> House Road. Apparently there was a crude oil release in December 2003 caused by farming <br /> equipment. This is not a site I am familiar with and it has not been assigned to anyone <br /> in the Private Sites Cleanup Section. Since my senior Wendy Cohen is on vacation until <br /> 10/18, I am trying to gather information regarding the site. Anything you can tell me <br /> about the site would be appreciated. <br /> Thank you, <br /> 1 <br />
