in 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, and impacts would be less than significant. Moreover, although impacts of the environment on a project do not require analysis or mitigation under CEQA and the proposed Project would not result in impacts on future users and residents, Mitigation Measure HAZ-2 is included and requires the Project applicant to conduct testing or design buildings to ensure that future users and residents of the proposed Project are not exposed to elevated levels of vapors (Draft Supplemental EIR at p. 5.6-25). Plans, Program and Policies (PPPs): PPP HAZ-1: SCAQMD Rule 1403. As listed previously. PPP HAZ-2: Lead. As listed previously. PPP WO-1: NPDES%SWPPP. Prior to issuance of any grading or demolition permits, the applicant shall provide the City Building and Safety Division evidence of compliance with the National Pollutant Discharge Elimination System (NPDES) requirement to obtain a construction permit from the State Water Resource Control Board (SWRCB). The permit requirement applies to grading and construction sites of one acre or larger. The Project applicant,/proponent shall comply by submitting a Notice of Intent (NOI) and by developing and implementing a Stormwater Pollution Prevention Plan (SWPPP) and a monitoring program and reporting plan for the construction site. PPP WQ-3: WQMP. Prior to the approval of the Grading Plan and issuance of Grading Permits a completed Water Quality Management Plan (WQMP) shall be submitted to and approved by the City Building and Safety Division. The WQMP shall identify all Post -Construction, Site Design, Source Control, and Treatment Control Best Management Practices (BMPs) that will be incorporated into the development project in order to minimize the adverse effects on receiving waters. Mitigation Measures: Mitigation Measure HAZ-1: Soil Management Plan (SMP). As listed previously. Mitigation Measure HAZ-2: Prior to issuance of a building permit for a future building within the Specific Plan area, the Project applicant shall, at its election, undertake one of the following three activities: (1) perform a subsurface soil vapor assessment demonstrating that vapor concentrations are within established limits for vapor intrusion into future buildings; (2) prepare a human health risk assessment (HHRA) demonstrating that documented levels of soil vapor do not represent a significant health risk to occupants of the future buildings; or (3) submit plans for a vapor intrusion mitigation system (VIMS) to be installed beneath the foundation of the future buildings. The Project applicant may rely on different measures of the foregoing options in different parts of the Specific Plan area. F. Noise Impact Finding: The Project would not result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the Project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies (Draft Supplemental EIR at p. 5.9-13).
