Executive Summary Environmental Impact Report ES-9 Impact Mitigation Measure (s) Residual Impact repository of the CHRIS, per CCR Guidelines Section 15126.4(b)(3)(C). Greenhouse Gas Emissions Impact GHG-1. The proposed project would include new natural gas connections, which would have the potential to contribute to the long- term generation of GHG emissions affecting the environment. This impact would be significant and unavoidable. No feasible mitigation measures are available. Significant and unavoidable. Impact GHG-1. The proposed project would include new natural gas connections, which would have the potential to contribute to the long- term generation of GHG emissions affecting the environment. This impact would be significant and unavoidable. No feasible mitigation measures are available. Significant and unavoidable. The cumulative GHG impacts of the proposed project would be significant. No feasible mitigation measures are available. Significant and unavoidable. Hazards and Hazardous Materials Impact HAZ-1. The project has the potential to create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment due to potential hazardous materials that may be present in the existing on-site structures and soils and groundwater. In addition, because of existing soil and groundwater contamination, the site is on a list compiled pursuant to Government Code Section 65962.5. This impact would be potentially significant but mitigable. HAZ-1 Project Demolition Activities. In conformance with State and local laws, a visual inspection/pre-demolition survey, and possible sampling, shall be conducted prior to the demolition of on-site building(s) to determine the presence of asbestos-containing materials (ACMs) and/or lead-based paint. Documentation of the survey shall be provided to the City of San Leandro prior to commencement of demolition activities. During demolition activities, all building materials containing lead-based paint shall be removed in accordance with Cal/OSHA Lead in Title 8, California Code of Regulations (CCR), Section 1532.1, including employee training, employee air monitoring, and dust control. Any debris or soil containing lead-based paint or coatings shall be disposed of at landfills that meet acceptance criteria for the type of lead being disposed. All potentially friable asbestos containing materials (ACMs) shall be removed in accordance with National Emission Standards for Air Pollution (NESHAP) guidelines prior to demolition or renovation activities that may disturb ACMs. All demolition activities shall be undertaken in accordance with Cal/OSHA standards contained in Title 8, CCR, Section 1529, to protect workers from asbestos exposure. A registered asbestos abatement contractor shall be retained to remove and dispose of ACMs identified in the asbestos survey performed for the site in accordance with the standards stated above in this mitigation measure. Materials containing more than one-percent asbestos are also subject to Bay Area Air Quality Management District regulations. Removal of materials containing more than Less than significant.
