Ms. Lucy Linnaus 3 June 1, 2010 <br /> Senior Planner <br /> <br /> Air Quality Analysis and Mitigation Measures: <br /> Siting Criteria and Future Proiect Planning <br /> 1. The AQMD staff recognizes the proposed project provides regional air quality <br /> benefits by increasing residential densities near future employment and transportation <br /> centers. However, the proposed project (Transit Zoning Code) provides a mixed use <br /> overlay zone for select areas that allows for mixed use development at the discretion <br /> of the property owner. As a result, the proposed project could place additional <br /> residential uses (e.g., single family homes, condos, and apartments) in close <br /> proximity to industrial uses (e.g., auto body paint shops) and a major fieeway (i.e., <br /> Interstate 5). <br /> AQMD-4 <br /> Given that the proposed project allows for the placement of residential uses inclose <br /> proximity to industrial uses and Interstate 5, the AQMD staff is concerned about the <br /> exposure of local residents to potentially significant sources of emissions. Therefore, <br /> AQMD staff recommends that the lead agency review the CARB Handbook, which <br /> offers guidance on the siting of incompatible land uses and "sensitive land uses" (e.g., <br /> residences, parks and medical facilities) near industrial sources, high traffic freeways <br /> and roads to design the proposed project. Further, AQMD staff requests that the lead <br /> agency implement mitigation measures consistent with the advisory recommendations <br /> and respective source categories in the CARB Handbook. <br /> Construction Mitigation Measures <br /> 2. The regional and localized construction emissions from implementing the proposed <br /> project could potentially exceed the AQMD's daily significance thresholds for NOX, <br /> VOC, CO, PM10 and PM2.5, therefore, AQMD staff is concerned about the overall <br /> implementation and effectiveness of the lead agency's construction related mitigation <br /> measures. Specifically, AQMD staff recommends that where the phrases: "to the AQMD-5 <br /> extent readily available," "to the extent cost effective" and "to the extent feasible" <br /> appear in mitigation measures (i.e., MM4.2-7, 4.2-9, 4.2-ll, 4.2-19, and 4.2-20) that <br /> the lead agency develop criteria to determine the "availability", "cost effectiveness" <br /> and "feasibility" of these measures. <br /> Additionally, AQMD staff requests that the lead agency consider adding the <br /> following mitigation measures to further reduce air quality impacts from the proposed <br /> project: <br /> Reroute construction trucks away from congested streets or sensitive receptor <br /> areas, <br /> AQMD-6 <br /> Consistent with measures that other lead agencies in the region (including Port <br /> of Los Angeles and Port of Long Beach) have enacted, require all on-site <br /> construction equipment to meet EPA Tier 2 or higher emissions standards <br /> according to the following: <br /> ? April 1, 2010, to December 31, 2011: All offroad diesel-powered <br /> construction equipment greater than 50 hp shall meet Tier 2 offroad <br /> <br />
