22requires the developer to submit Form 7460 -1 (Notice of Proposed Construction or Alternation) to the Federal Aviation Administration (FAA) and adherence to all local, state, and federal regulations would ensure that a safety hazard does not occur as a result of the proposed project. Therefore, this impact would be less than significant with the incorporation of mitigation measure MM HAZ -3. (3) Emergency Plans. Construction activities associated with Option 1 or Option 2 could temporarily result in lane closures on adjacent roadways that could interfere with emergency plans. However, mitigation measure MM HAZ-4 would ensure that construction of the proposed project would not impede emergency evacuations that could occur within the City by requiring that emergency response teams for the City of El Segundo, including the ESPD and ESFD, are notified of lane closures during construction activities in the project area and that one lane would remain open at all times to provide adequate emergency access to the site and surrounding neighborhoods. Therefore, this impact would be less- than - significant with the incorporation of mitigation measure MM HAZ -4. b) Mitigations: MM HAZA Before demolition and /or construction activities, the proposed project site must be tested for asbestos and lead by a licensed contractor. The contractor must follow all applicable local, state, and federal codes and regulations related to the treatment, handling, and disposal of asbestos and lead if the proposed project requires asbestos and /or lead abatement. MM HAZ -2 In the event that previously unknown or unidentified soil and /or groundwater contamination that could present a threat to human health or the environment is encountered during construction at the project site, construction activities in the immediate vicinity of the contamination must cease immediately. If contamination is encountered, a Risk Management Plan must be prepared and implemented that (1) identifies the contaminants of concern and the potential risk each contaminant would pose to human health and the environment during construction and post - development and (2) describes measures to be taken to protect workers and the public from exposure to potential site hazards. Such measures could include a range of options, including, without limitation, physical site controls during construction, remediation, long -term monitoring, post - development maintenance or access limitations, or some combination thereof. Depending on the nature of contamination, if any, regulatory agencies must be notified (e.g., El Segundo Fire Department). If needed, a Site Health and Safety Plan that meets Occupational Safety and Health Administration requirements must be prepared and in place before commencement of work in any contaminated area. 12
