4.9 PUBLIC HEALTH AND SAFETY This section has been prepared based on two Phase I Environmental Site Assessments(ESA)prepared for the proposed project by ENGEO Incorporated(ENGEO),hic. dated April 15,2004 and November 2,2004; a Pipeline Risk assessment prepared for the proposed project by J House Environmental dated June 2004; and independent research and analysis on electromagnetic fields(EMFs). The Phase I ESAs,which were prepared consistent with American Society of Testing Materials(ASTM) standards,covers the 815-acre project site and Grant Line Road expansions along with the proposed off-site infrastructure locations(collectively,the"survey area,"Figure 4.9-1). It includes the results of a hazardous materials historical review,records search,and site reconnaissance; a literature review (including a review of ' previous environmental reports covering the property); and interviews with knowledgeable private and public sector officials.The purpose of the Phase I ESAs is to identify the presence or likely presence of hazardous materials at the project site,and identify the potential for project activities to cause human exposure to these materials.The Phase I ESAs are included in their entirety as Appendices M and N of this Draft EIR. The Pipeline Risk assessment,which was prepared consistent with California Department of Education(CDE) guidelines for school siting,addresses three Pacific Gas&Electric Company(PG&E)natural-gas pipelines and one Chevron crude-oil pipeline that bisect the College Park site,and a fourth PG&E natural gas pipeline located off-site but in the general vicinity of the project site.It includes information concerning the pipelines from PG&E, Chevron,and the California State Fire Marshall(CSFM)Pipeline Safety Program; identification of events that could lead to pipeline failure; an assessment of the probability or frequency of these events; and an evaluation of the consequences of any such events.The purpose of the Pipeline Risk Analysis is to identify potential safety hazards associated with the pipelines and to estimate risks associated with new development in proximity to the pipelines.The Pipeline Risk assessment is included in its entirety as Appendix K of this Draft EIR. The independent research and analysis of EMFs addresses the health effects associated with EMFs,what is generally accepted as a safe distance for sensitive land uses(schools,residential)near high tension power lines to avoid EMF-related adverse health effects, and an analysis of whether the proposed project would expose sensitive uses to those effects. 4.9.1 PHYSICAL SETTING The College Park project site includes a mixture of existing single-family residential,agricultural,and infrastructure uses(see Figure 4.2-1,in Section 4.2,"Land Use and Agriculture').A large portion of the site is in agricultural production of alfalfa,oats,sugar beets,and corn crops.The eastern portion of the site,along Mountain House Parkway,contains two dairies,one on each side of Grant Line Road.The central portion of the site contains four residences,and one residence is located within the dairy properties south of Grant Line Road and on Grant Line Road halfway between Mountain House Parkway and the Alameda County line.The northwest portion of the site _ contains 50 residences in a community know as Grant Line Village.Two Byron-Bethany Irrigation District(BBID) irrigation canals,a 65-foot-wide PG&E and Chevron easement containing two large natural gas transmission pipelines and a crude oil pipeline,a smaller PG&E easement containing a smaller natural gas transmission line,and a 75-foot-wide PG&E electrical easement containing 230 kilovolt ampere(kVA)overhead transmission lines,bisect the project site.The remainder of the site is fallow or used for grazing.The proposed off-site infrastructure locations (Figure 4.2-1)contain a residence and agricultural fields(137-acre Pombo property), existing streets and vacant area (Grant Line Road and Mountain House Parkway),and undeveloped areas(pipeline corridors north of Grant Line Road).One of the off-site infrastructure locations also includes a portion of the Mountain House Wastewater Treatment Plant(W WTP)where a pipeline is proposed between the plant and the Pombo property(see Figure 3-14, in Chapter 3,"Project Description'). The Grant Line Road expansion area consists of shoulder areas,the associated on/offramps from Interstate 580 (I-580)to Grant Line Road, and the intersections of Grant Line Road with Mountain House Parkway and Hansen College Park at Mountain House Specific Plan III Draft EIR EDAW San Joaquin County 4.9-1 Public Health and Safety
