Cherokee Lane <br /> Lodi, California <br /> SECOR Project No.: 77BP.00760.01.0136 <br /> Dear Mr. Barton: <br /> This addendum to the workplan prepared by SECOR International Incorporated (SECOR) <br /> on behalf of Atlantic Richfield Company, a BP Affiliated Company, addresses the comments <br /> in the Regional Water Quality Control Board (RWQCB) letter dated December 21, 2006 <br /> (Attachment A). The letter was prepared in response to the SECOR workplan dated <br /> December 15, 2006. The purpose of the addendum to the workplan is to present a map <br /> showing additional groundwater monitoring wells and soil vapor probe locations. <br /> As requested in the RWQCB letter, one additional groundwater monitoring well (MW-9) has <br /> been added to the southeast of the site to delineate the downgradient extent of the <br /> contamination. In addition, one additional soil vapor probe (VP-4) has been proposed. The <br /> additional probe is located along the western property line near the residence. The <br /> additional locations are shown on the attached Figure 2. All other aspects of the previous <br /> workplan submittal remain unchanged. <br /> Should you have any questions regarding this project, please feel free to contact the <br /> undersigned at (916) 861-0400 ext 229. <br /> Sincerely, <br /> QROFESS/pN <br /> SECOR International Incorporated Q�� E.
