S E C O R <br /> Ms . Devra Lewis <br /> January 13, 2005 <br /> Page 3 <br /> FINDINGS <br /> Utilities identified during the "field meet" are shown on Figure 2. East of Tracy Boulevard , <br /> the BAPL typically trends east-west slightly north of the centerline of Grant Line Road . <br /> Through the intersection of Grant Line Road and Tracy Boulevard , the BAPL trends slightly <br /> to the west-northwest. West of the intersection , the BAPL trends east-west along the north <br /> side of Grant Line Road . <br /> East of Tracy Boulevard and through the intersection of Grant Line Road and Tracy <br /> Boulevard , the PG&E pipeline trends east-west along the south side of Grant Line Road . <br /> West of the intersection , the PG&E pipeline makes several abrupt changes in trend until it <br /> finally assumes its original east-west trend . The PG &E field representative indicated that <br /> the abrupt changes in trend were a result of encountering soil contamination in the <br /> subsurface along Grant Line Road just north of the UNOCAL 76 station located at 2375 <br /> Tracy Boulevard . <br /> Telecommunication lines of AT&T and SBC occupy the same trench and trend east-west <br /> along the north side of Grant Line Road . <br /> Storm sewer and water line locations were evaluated by Cruz Brothers . Cruz Brothers <br /> indicated that these lines trended east-west along the south side of Grant Line Road <br /> throughout the site vicinity. <br /> GROUNDWATER-FL-OW-RUSE DIAGRAM <br /> Quarterly groundwater elevation data for the period from May 27, 1995 to October 28, 2004 <br /> for monitoring wells at Chevron Service Station 9-8632 were used to evaluate groundwater <br /> flow directions. These flow directions were used to construct the groundwater flow rose <br /> diagram presented in Figure 3. Groundwater flow data presented in the rose diagram <br /> indicate that the predominant flow direction for the period analyzed has been to the <br /> northwest and north-northwest. There is a minor component of groundwater flow to the <br /> east. <br /> PIPELINE THROUGHPUT AND TESTING RECORDS REVIEW <br /> CTPL will not release pipeline throughput data and construction details due to Homeland <br /> Security and proprietary concerns . Information regarding product types historically <br /> transported through the system and historic release data will be submitted under separate <br /> cover prior to February 4, 2005. CEMC requests that all future directives from the RWQCB <br /> in regards to the BAPL be made to Diane Russell of CTPL. Ms. Russell's contact <br /> information is presented below: <br /> I:\Chevron\302792\Reports\Chevron Pipeline Assessment Report RevA.doc <br />
