based on the general anticipated construction schedule, including duration for each construction subphase, anticipated equipment for each construction subphase, and estimated earthwork movement (if applicable), as provided to PlaceWorks. Project -related construction emissions will be compared to the South Coast Air Quality Management District (SCAQMD) regional significance construction thresholds. Localized air pollution impacts from onsite construction equipment exhaust and fugitive dust generated at each proposed park site will also be compared to SCAQMD's screening -level localized significance thresholds (LST) for their potential to elevate concentrations of air pollutants at the adjacent land uses surrounding the project site. If necessary, mitigation measures will be identified to reduce any potentially significant regional and/or localized air quality impacts. Operational Phase. Based on the preliminary information received, the proposed parks would generally consist of open play areas and ancillary structures (e.g., restrooms) that would generate minimal to no operation -phase criteria air pollutant and GHG emissions from energy and area sources. Additionally, it is assumed that the proposed parks would serve the local communities and would generate only limited vehicular traffic that would result in nominal mobile -source emissions. Thus, the technical analysis will provide a qualitative discussion describing potential operational -phase air quality and GHG emissions impacts associated with the proposed parks. Other Areas of Impact The SoCAB is currently designated nonattainment under the National and/or California ambient air quality standards (AAQS) for ozone (03), fine inhalable particulate matter (PM2.5), coarse inhalable particulate matter (PM10), and lead (Los Angeles County only). The SCAQMD has adopted the 2016 Air Quality Management Plan (AQMP). The AQMP is prepared to ensure the SoCAB can attain the long-term National and California AAQS. The air quality analysis will include a consistency evaluation of the project's regional emissions to SCAQMD's AQMP. Furthermore, the SoCAB has been designated in attainment for carbon monoxide (CO) under both the California and National AAQS. Therefore, the air quality analysis will include only a qualitative assessment of CO hotspots. In addition, the environmental document will also include a qualitative assessment of potential odor impacts. Project Conslstency with Plana Adopted to Reduce GHG EmLsslons. The GHG section will discuss the GHG reduction goals of Assembly Bill 32 (AB 32), Senate Bill 32 (SB 32), and SB 375. To achieve the GHG reduction targets of AB 32, the California Air Resources Board (GARB) prepared the 2008. Scoping Plan and a 2014 update. CARE also recently released a draft of the 2017 update to achieve the SB 32 reduction target. In addition, the Southern California Association of Governments (SCAG) has adopted a regional transportation plan/sustainable communities strategy (2016-2040 RTP/SCS) to ensure that the southern California region can attain the regional transportation -related GHG reduction goals of SB 375. Furthermore, the City has prepared a Climate Action Plan. Project consistency with these statewide, regional, and local GHG emissions reduction strategies and plans will be reviewed. Biological Resources There are no natural biological habitats on either site, and impacts to biological resources are noy anticipated. Cultural Resources The cultural resources studies listed above will be used in preparing the related sections in the NEPA and CEQA documents for Sites 1 and 2. November 27, 2017 I Page 6 25E-19
