The pipeline section in <br /> particular runs southeast-northwest,in the vicinity of Hansen Road(Figure 2) <br /> BACKGROUND <br /> Site Description <br /> The site is located in the western portion of the Central Valley,within the City limits of <br /> Tracy,and is situated south of Hansen Road and west of Schulte Road(Figure 2). The <br /> area is currently undeveloped and slopes topographically toward the northeast. The <br /> subject site consists of an approximately 3000 foot section of two former Shell Oil <br /> Company pipelines. Shell operated two 8-inch diameter pipelines in the area for <br /> conveyance of crude oil. The property through which the lines ran is scheduled for <br /> development at some point in the future,and as a consequence,Shell agreed to remove <br /> the piplines. During pipeline removal,some areas surrounding the pipelines were <br /> observed to be impacted by hydrocarbons. In total,six areas along the pipeline were <br /> noted to exhibit impact(Figure 3). <br /> h <br /> - <br /> NdPRO16C1aVrr>:iidu�i i <br /> SAN JOAQUIN COUNTY <br /> ENVIRONMENT HEALTH DIVISION "+ <br /> 04 E YYYbw Avw,T'hMd Roo►11110010M CA <br /> # f <br /> F1 <br /> mod <br /> Apprwad IM ahelt�af M INAMI lr <br /> o w�. <br /> Re� LEmE,tTi <br /> "Ea - <br /> t <br /> t <br /> o lni s c�T o visrt it <br /> i <br /> Pve. <br /> 6 <br /> N Su.EFIh'AS �L <br /> Date $'3/-07 <br /> Approval of tI plane efdertda titiat vI1NIoh Y <br /> shown and described tree On but dM not allftrin <br /> or approve any ommission or deviation of requirements <br /> of Stet= !-�- nr Local Ordinsnrtac <br /> I - ...wur•aer i <br />
