ONE BROADWAY PLAZA PROJECT EIR ADDENDUM <br />CITY OF SANTA ANA <br />5. Environmental Analysis <br />required to comply with NPDES Permit requirements and implement best management practices to ensure the <br />proper handling of hazardous materials and to contain and clean up accidental releases. Construction of the <br />Approved Project would temporarily increase the transport of hazardous substances, such as vehicle fuels and <br />paints. Further, the construction of the Approved Project would demolish buildings that likely contain asbestos - <br />containing materials and lead -based paint. <br />The Phase I Environmental Site Assessment (ESA) prepared for the Approved Project determined that there <br />are no unusual hazardous conditions at the Project Site. <br />The Certified EIR determined that the operation of the Approved Project would include minimal hazardous <br />material use and waste. The presence of chemicals onsite, if not properly stored or handled could expose site <br />occupants to hazardous materials. The Certified EIR determined that the potential for significant adverse <br />impacts to offsite uses is unlikely given the nature and limited about of materials. Compliance with regulatory <br />measures, including the preparation of a Hazardous Materials Management Plan, would reduce impacts of <br />hazardous materials during the operation of the project. <br />The Certified EIR determined that the demolition of buildings on -site may contain asbestos materials and lead - <br />based paint. Hazardous materials could be used in the construction and operation of the Approved Project. <br />Mitigation measures would reduce these impacts to a less than significant level. <br />The Initial Study for the Certified EIR determined that the Project Site is not within a two-mile radius of a <br />public airport and no private airstrips are located in the vicinity of the Project Site. The Certified EIR addressed <br />the Approved Project's impact to air transportation in the Transportation and Traffic section. The Project Site <br />is located outside of the Accident Potential Zone for the John Wayne Airport. The Certified EIR determined <br />that the Approved Project would be required to comply with FAA Part 77 regulations. <br />The Initial Study for the Approved Project determined that the Project Site is located in an urbanized area and <br />would not be subject to wildland fires. <br />Apri12020 Page 57 <br />
