ENVIRONMENTAL IMPACT REPORTADDENDUM Bristol Street Widening Project Warner Ave to Saint Andrew Place (Phase IV) BRISTOL ST (WARNER TO MEMORY LANE) WIDEN FROM 4 TO 6 LANES (IMPV AT BRISTOL /WARNER (ADD NBIEBISB TI3RU LAS, WB RT TRY LN) AND BRISTOL /FIRST (ADD NBISB THRULNS; SB LFTIR TITRN LNS The Phase IV Project's design concept and scope have not changed significantly from what was analyzed in the RTIP and FTIP. This analysis found that the plan and, therefore, the individual projects contained in the plan, are conforming projects, and would have air quality impacts consistent with those identified in the state implementation plans (SIPS) for achieving the National Ambient Air Quality Standards (NAAQS). FHWA determined the RTIP to conform to the SIP. The Phase IV Project's open to the public year is consistent with (within the same regional emission analysis period as) the construction completion date identified in the FTIP and/or RTP. The FTIP gives priority to eligible TCMs identified in the SIP and provides sufficient funds to provide for their implementation. FHWA determined the TIP to conform to the SIP on December 2010. The Phase IV Project is also included in the 2013 TIP adopted by SCAG on September 6, 2012 and approved by FHWA on December 14, 2012. The Proposed Widening of Bristol Street, from Warner Avenue to Memory Lane project has been included in the federal TIP since 1992. The federal TIP gives priority to eligible TCMs identified in the SIP and provides sufficient funds to provide for their implementation. FHWA determined the TIP to conform to the SIP on April 2, 2009. No significant impacts would occur. Implementation of the proposed project would not result in greater impacts than previously analyzed in the 1990 Final EIS /EIR. Furthermore, the South Coast Air Basin (SCAB) is designated by the state and US Environmental Protection Agency (EPA) as nonattaimnent for ozone (03 ), and particulate matter (PM10 and PM2.5 ). The South Coast Air Quality Management District (SCAQMD) developed regional emissions thresholds to determine whether or not a project would contribute to air pollutant violations. If a project exceeds the regional air pollutant thresholds, then the project would substantially contribute to air quality violations in the SCAB. In addition, a project would also contribute to air pollutant violations if localized emissions result in an exceedanee of the ambient air quality standards (AAQS). Short -term emissions generated during project - related construction activities would not exceed the SCAQMD regional emissions thresholds for any of the criteria pollutants and also would not substantially elevate localized concentrations of these pollutants. Consequently, the project would be consistent with the AQMP. Long -tern emissions generated by the project would not exceed the SCAQMD thresholds for regional emissions and would therefore also not contribute to an increase in frequency or severity of air quality violations. The proposed project would be consistent with the Major Arterial designation of the City of Santa Ana General Plan Circulation Element and the County of Orange's Master Plan of Arterial Highways. Additionally, the project would improve traffic flow and result in a reduction in air pollutant emissions. Mitigation Measures No additional new mitigation measures are required. (b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Short -tern emissions were modeled for the construction phase of the proposed street widening project. Construction activities associated with the project would include demolition of pavement and buildings, fine grading, trenching, paving, and development of ancillary strictures. During construction activities, emissions from heavy equipment exhaust, delivery trucks, and fugitive dust would be generated for a short duration.
