Environmental Impacts of the Proposed Changes to the Original Project Addendum to the City of Pleasanton Downtown Specific Plan Final Environmental Impact Report 43 release of asbestos and lead into the environment. Demolition and construction would be required to comply with BAAQMD Regulation 11, Rule 2, which intends to control the emission of asbestos during demolition and construction activities. Rule 2 requires surveys for asbestos to be conducted prior to demolition activities that would disturb materials that might contain asbestos. BAAQMD also collects fees for demolition activities subject to this rule (BAAQMD 2018). Construction would also be required to comply with California Code of Regulations, Section 1532.1, which requires testing, monitoring, containment, and disposal of lead-based materials, such that exposure does not exceed CalOSHA standards. Compliance with BAAQMD and State regulations would minimize the emission of asbestos during project demolition, and impacts would be less than significant. As discussed in the Final EIR, the operation of residential and commercial uses would not require the routine use, transport, and disposal of hazardous materials, and likewise, the commercial and residential uses proposed as part of the project would not involve hazardous materials other than those used for typical household and landscape activities and vehicular operation. The minimal amounts of household hazardous wastes on-site would not create a significant hazard to the public or the environment. However, given the presence of up to two feet of soils contaminated with lead on the project site, there would be the potential for future residents to be exposed to contaminated soils. City of Pleasanton General Plan Program 17.1 calls for environmental investigations to ensure that soils, groundwater, and buildings affected by hazard material releases from prior land uses, including lead, would not have the potential to affect the health and safety of future property owners or users. Since the environmental investigation (Phase I ESA and Subsurface Investigation, as included as Appendix E) found lead soil contamination, the City would apply a COA to implement this General Plan program. Suggested text for the implementing COA is presented below. With implementation of COAs as required by General Plan Program 17.1, this impact would be less than significant. Condition of Approval  Soil Remediation: Where soil is identified to be present within the construction envelope at the project site at chemical concentrations exceeding ESLs and/or hazardous waste screening thresholds for contaminants in soil (California Code of Regulations [CCR] Title 22, Section 66261.24), the project applicant shall retain a qualified environmental consultant (PG or PE) to properly dispose of the contaminated soil. The qualified environmental consultant shall utilize the project site analytical results for waste characterization purposes prior to offsite transportation or disposal of potentially impacted soils or other impacted wastes. The qualified consultant shall provide disposal recommendations and arrange for proper disposal of the waste soils or other impacted wastes (as necessary), and/or provide recommendations for remedial engineering controls, if appropriate. Remediation of impacted soils and/or implementation of remedial engineering controls may require additional delineation of sub- surface impacts; additional analytical testing per landfill or recycling facility requirements; soil excavation; and offsite disposal or recycling. The City shall review and approve the project site disposal recommendations prior to transportation of waste soils offsite, and review and approve remedial engineering controls, prior to construction. The project applicant shall review and implement the project site disposal recommendations prior to transportation of waste soils offsite and review and implement the remedial engineering controls prior to construction. The City shall review and approve the project site disposal recommendations and remedial engineering controls prior to issuing a grading permit.
