FilioslDoblerAnnexation iand Development Project <br /> Environmental Impact Report TRACY <br /> result in.thc release of ACMs or LBPs must be conducted according to federal and-state laws and <br /> regulations. <br /> The National Emission Standards for Hazardous Air Pollutants (NESHAP), implemented through the: <br /> SJVAPCD Rule 4002, mandates that building owners conduct an asbestos survey to determine the <br /> presence of ACMs prior to the commenccrrient of any remedial work, including demolition. If ACM <br /> material is found, abatement of asbestos would.be required prior to .any demolition activities. Also, if <br /> paint is separated from building materials (chemically or physically) during demolition of the structures.- <br /> the-paint <br /> tructures.the-paint waste would be required to be.evaluated independently from the building material by a qualified <br /> Environmental Professional. If.lead-based paint is found and is.separating'from the building material, <br /> abatement would be required to be completed by a qualified Lead Specialist-prior,to any demolition <br /> activities. Compliance with Mitigation Measures 4.10-1a and 4.10-1b'and compliance with STVAPCD <br /> Rule 4002 would reduce potential impacts in this regard to less than significant levels. <br /> Agricultural Activities <br /> r <br /> f no hazardous The Project site is currently utilized for agricultural purposes. .Based on the EHMCA, <br /> materials contamination has resulted at the.Project site due to current agricultural operations. However, j ! <br /> the Project site has been historically utilized for agricultural purposes(since prior to 1957 until the present <br /> day). Therefore; a combination of several commonly-used pesticides (i.e., DDD, DDT and DDE);which <br /> are now banned,may.have been used throughout the Project site(particularly from the 1940s through the <br /> 1960s). The historical use of agricultural pesticides may have resulted in pesticide residues of certain <br /> persistence in soil at concentrations that are considered to be'hazardous based on established federal <br /> regulatory levels. The primary concern with historical pesticide residues is human health risk from <br /> inadvertent ingestion of contaminated soil, particularly by children. The presence of moderately elevated <br /> pesticide residuals in soil presents potential health and marketplace concerns. <br /> Development at the Project site could expose construction workers(during site disturbance activities)and 3 <br /> the public (during operations) to hazardous materials.. Future development at the Project site would be <br /> required to conduct soil sampling within the portions of the Project site that have historically been utilized <br /> for agricultural purposes and may contain pesticide residues in the soil (as detennined by a qualified <br /> Phase II/Site Characterization specialist). The sarnpling, conducted in consultation with the EHD, would <br /> determine if pesticide concentrations exceed established regulatory requirements and would identify <br /> further site characterization and remedial activities, if necessary. Should further site <br /> characterization/remedial activities be required, these activities would be required to be conducted per the <br /> applicable regulatory agency requirements, as directed by the EHD. With implementation of Mitigation <br /> Measure 4.10-1c, impacts pertaining'to historical agricultural uses would be reduced 'to less than <br /> j significant levels. <br /> Known Contamination from Reported Spills <br /> r <br /> There is reported residual crude oil and Bunker C oil in the soil along the southern portion of the Project <br /> site as a result of two offsite oil pipelines (the OVP and TAOC pipelines). Site investigations have been . <br /> l <br /> undertaken by Chevron for properties along the historical pipelines which included portions of the <br /> Project site). Crude oil affected soil, later attributed to the OVP/TAOC leaks, were identified. Based on <br /> past investigations at the Project site, very-limited petroleum hydrocarbon-affected soil was encountered <br /> at four to 15 feet bgs. Detected constituents (pyrene and chrysene) as well. as benzene, toluene, <br />` ethylbenzene, xylenes, and PAHs were below their respective residential PRGs, indicating that the r <br /> presence of these constituents in soil at the site do not pose.an unacceptable risk to future onsite residents. <br /> There were no detections of dissolved-petroleum constituents in groundwater.
