However, due to the <br /> elevated levels of TPH gasoline detected at Boring B2 at depths of 15 <br /> and 20 ft below ground surface, we recommend that a total of 3 <br /> confirmation soil samples be collected from the bottom of the excavation <br /> area. We suggest that one of the three samples be collected from the <br /> approximate area of Boring B2 . <br /> Thank you for your consideration of DTSC's comments Lori. We believe <br /> our current regulatory roles at this Site appropriate (SJCEHD as lead <br /> for the UST removal, and DTSC as lead for the investigation/remediation <br /> of the remaining orchard property) . Please let me know if you have any <br /> questions, or wish to discuss this Site further. Thanks, Maria <br /> Maria Gillette <br /> Work Phone # (916) 255-3953 <br /> Fax # (916) 255-3696 <br /> E-mail: MGillett@DTSC.ca.gov <br /> >>> "Lori Duncan [EH] " <lduncan@sjcehd.com> 9/6/2006 9:54 AM >>> <br /> Maria, I have looked over the Cabral/McAdams work plan just briefly; <br /> before approving it I would request that the consultant be more <br /> specific <br /> on the proposed depth of the excavation. <br /> The two borings the DTSC toxicologist has issues with were completed <br /> less than three feet from each other. Boring B-3 was done in a second <br /> phase of work and was located to vertically define the contamination <br /> noted at 20 feet bsg in boring B-2 . I would consider the area <br /> vertically defined, especially taking into consideration the lateral <br /> dimensions of the proposed excavation would cover both borings. <br /> However, <br /> I discussed DTSC's comments with my supervisor and we both think that <br /> if <br /> DISC has concerns with the excavation work plan it would probably be <br /> best if you took the lead on it. <br /> Lori Duncan <br /> SJC/EHD <br /> (209) 468-0337 <br /> -----Original Message----- <br /> From: Network Administrator [PHS] <br /> Sent: Tuesday, September 05, 2006 1:48 PM <br /> To: Lori Duncan [EH] <br /> Subject: FW: lduncan@sjcehd.com - Bayesian Filter detected spam - Fwd: <br /> Cabral-McAdams property <br /> This message was caught accidentally in the spam filter.
