3.0 Environmental Impact Checklist would represent a potentially significant hazard. Mitigation Measures HAZ-1 and HAZ-2 would require a ACMs and LBPs survey to be performed prior to demolish activities to prevent potential exposure to construction workers and to facilitate proper disposal of any hazardous wastes and reduce impacts to less-than-significant levels. Mitigation Measure HAZ-1: Prior to demolition, a complete asbestos survey shall be conducted in accordance with National Emissions Standards for Hazardous Air Pollutants(NESHAP) guidelines.All suspect asbestos-containing materials(ACMs) shall be sampled to determine the presence or absence of asbestos prior to building demolition activities. If ACMs are found, a licensed asbestos abatement contractor shall be retained to abate the identified ACMs. Mitigation Measure HAZ-2:Prior to demolition, a comprehensive lead based paint (LBP) survey shall be conducted. If any LBP is identified,it shall be removed from the site in accordance with all applicable regulations, including California Division of Occupational Safety and Health (Cal/OSHA)Lead in Construction Standard, as included in California Code of Regulations, Title 8,Section 1532.1, during demolition activities. These requirements include employee training, employee air monitoring, and dust control. If lead paint is peeling, flaking or blistered, it shall be removed prior to demolition. It is assumed that such paint will become separated from the building components during demolition activities and could become air-borne;therefore it shall be managed and disposed as a separate waste stream.Any debris or soil containing lead paint or coat shall be disposed at landfills that are permitted to accept the waste being disposed. After construction, the project would not involve the routine transport or disposal of hazardous materials and therefore,no associated impacts would occur. b) 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? Less-than-Significant Impact.Activities associated with project construction would utilize hazardous materials such as vehicle fuels and lubricants in small quantities.While these are commonly used materials, if handled improperly,they could pose a hazard to the public or environment.The required compliance with applicable federal, state, and County hazardous materials regulations would minimize risks to the public during project construction. The Phase I Environmental Site Assessment prepared for the project(Appendix D) included a search of the regulatory databases and identified the closest hazardous site having an unauthorized release of hazardous materials is located at 975 Woodside Road, approximately 317 feet to the east-southeast of the project site. The County of San Mateo Environmental Health Department granted case closure for the site in 2005 following remediation. Based on the case closure,the project site is located up-gradient from the hazardous material site. The direction of groundwater flow is away from the project site and therefore contamination of soil and groundwater underlying the project site from this hazardous material site is unlikely.
