Phase I Environmental Site Assessment Neighborhoods D,k,L,and Town Center,Mountain House,California Page 24 southern portion of Neighborhood L. A railroad right-of-way is Iocated along the southern boundary of Neighborhood L. Site reconnaissance revealed irrigation waterways, water pumps, and an electrical transformer are located along the northern portions of Neighborhoods K and L. Irrigation ditches and piping are located.throughout the Site properties. Warning signs indicating underground gas; petroleum, and water pipelines were observed along Kelso Road and Byron Road, Byron Road, and north. of the railroad right-of-way, respectively. Two old electrical transformers were observed stored on a pile of railroad ties in the northwestern portion of the small farm complex on Neighborhood D. Three electrical transformers were observed on the southeastern portion and one on the northwestern portion of APN 209-170-02; three were marked as non- PCB containing. File review information indicated that the 19822 W. Grant Line Road location had or possibly still has a 200- to 500-gallon farm LIST containing an unknown fuel in 1989.. This location does not appear to be a potential risk to the Site due to the small size of the tank and its distance to the Site. ` The future Mascot Boulevard and Altamont Parkway is the former location of the 8-inch and 10-inch diameter CVC pipelines formerly operated by Shell and reportedly removed in the 1960s (Figure 5, Appendix A). These two crude oil-carrying pipelines were located approximately five feet bgs and trended northwest/southeast through Neighborhood D and adjoining properties .to the west and south. According to a summary report, impacted soil and groundwater were noted on Neighborhood E in June 2003. Further soil and groundwater testing and remediation excavation activities were performed and localized petroleum hydrocarbon contamination of soil and groundwater were noted. One of these contamination areas is located on Neighborhood C. Ongoing investigation and remediation activities are being conducted by Shell in accordance with the requirements of SJCEHD and Central Valley Regional Water Quality Control Board. The abandoned Chevron crude oil pipeline, OVP, is located along the south side of Byron Road, between Neighborhood L and Town Center. Ongoing investigation and remediation activities are being conducted by Chevron Environmental Management Company in accordance with the requirements of SJCEHD and Central Valley Regional Water Quality Control Board. Review of provided preliminary title reports also indicated pipelines on several of the Site properties. i Resources from the Mountain House Master Plan indicated a small household waste dump area located in the northeastern portion of the adjoining western properties (Neighborhood C). Further interviews Findicated SJCEHD granted this area"No Further Action" status. One abandoned exploration gas well was formerly located within Neighborhood L and is shown in Figure 5, Appendix A. Two irrigation canals are located west of Neighborhood D. 9.0 OPINIONS AND CONCLUSIONS We (Condor) have performed a Phase I ESA in conformance with the scope and limitations of ASTM Practice E 1527'of parcels and/or portions of parcels designated as APNs 209-030-03 and --04; 209-040- 09, -14, and 717; 209-.050-09; 209-170-02; and 209-450-11, -12, and -13, the property.
