outlined below) and any contaminated soils found in concentrations above established thresholds shall be removed and disposed of according to California Hazardous Waste Regulations. The contaminated soil removed from the site shall be hauled off-site and disposed of at a licensed hazardous materials disposal site. A SMP will be prepared to establish management practices for handling impacted groundwater and/or soil material that may be encountered during site development and soil-disturbing activities. Components of the SMP will include: a detailed discussion of the site background; preparation of a Health and Safety Plan by an industrial hygienist; notification procedures if previously undiscovered significantly impacted soil or free fuel product is encountered during construction; on-site soil reuse guidelines based on the California RWQCB, San Francisco Bay Region's reuse policy; sampling and laboratory analyses of excess soil requiring disposal at an appropriate off-site waste disposal facility; soil stockpiling protocols; and protocols to manage ground water that may be encountered during trenching and/or subsurface excavation activities. Prior to issuance of grading permits, a copy of the SMP must be approved by the Community Development Director. Asbestos and Lead Based Paint Due to the age of the structures on the project site, ACMs may be present. The project proposes to demolish the existing buildings and as a result, an asbestos survey must be conducted under National Emission Standards for Hazardous Air Pollutants (NESHAP) guidelines. In addition,NESHAP guidelines require that all potentially friable ACM be removed prior to building demolition that may disturb the ACMs. Based on the age of the buildings,lead-based paint may also be present. If lead-based paint is still bonded to the building materials,its removal is not required prior to demolition. It will be necessary, however,to follow the requirements outlined by Cal-0SHA Lead in Construction Standard, Title 8, California Code of Regulation (CCR) 1532.1 during demolition activities; these requirements include employee training, employee air monitoring, and dust controL If lead based paint is peeling, flaking, or blistered,it should be removed prior to demolition. It is assumed that such paint will become separated from the building components during demolition activities and must be managed and disposed of as a separate waste stream. Any debris or soil containing lead paint or coating must be disposed of at landfills that are permitted to accept such waste. Demolition of the existing structures on the project site could expose construction workers or residents in the vicinity of the project site to harmful levels of ACMs or lead. The proj ect is required to conform to the following existing regulatory programs and to implement the following measures to reduce impacts due to the presence of ACMs and/or lead-based paint: • 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 buildings to determine the presence of asbestos-containing materials and/or lead-based paint.
