5. Environmental Analysis <br />AIR QUALITY <br />In additicn to the requirements under AB 32, to address G HG emission and global climate change in general <br />plans and CE OA documents, Senate Bill 9 (Chapter 135, 2097) requires the Governor's Office of Planning <br />and Research (OP R) to develop CEOA guidelines on how to address global warm ing emissions and mitigate <br />project - generated GHG. OP R is required to prepare, develop, and transmit these guidelines on or before July <br />1, 2099, and to adopt the CE QA guidelines by January 1, 2010. In June 2998, OP R released the Technical <br />Advisory for addressing climate change through CEQA review, Based on this guidance document, OPR <br />recommends that projects identify and quantify GHG emissions, assess the significance of the impact on <br />climate change, and if determined to be significant, identify alternatives and/or mitigation measures that <br />could reduce the impact (PR 2908). <br />Existing Ambient Air Quality <br />Existing I eve Is of ambient air quality and historical trends and projec #ions in the vicinity of the project site and <br />the City of Santa Ana are best documented by measurements ,Wade by the SCAQMD. The project site is in <br />Source Receptor Area R) 1 - central Orange County. The air quality monitorirng station in S RA 17 is the <br />Anaheim -Loara School Monitoring Station. Data from this station is summarized in Table 5.1 -3. The data <br />shover recurring violations of both the state and federal ozone standards and no clear trend is apparent. The <br />data also indicate that the area regularly exceeds the state PM10 ambient air quality standards and <br />occasionally exceeds the federal PM,, and state PM, standards. Neitherthe CO nor N 2 standard has been <br />violated in the last five gears at this station. <br />Table 5,1-3 <br />Ambient Air Quality A oral erincx Summa <br />Fine Particulates P1 <br />Federal 24 -Hour > 851 m, 0 0 0 1 <br />Max. 4 -Hour Con g/m) 115.5 .0 54.7 50.2 70.4 <br />Source: South Coast Air Quality Management District, Ambient Air Quality Monitoring Data. <br />ppm: parts per million; erg /ml: or micrograms per cubic meter; NS: No Standard. <br />' The US EPA recently reprised the 8 -hour 03 standard from 0.08 ppm to 8.075 ppm, effective May 2008 <br />2 The NQ, standard was amended on February 22, 2007, to lower the 1 -hr standard to 0.1 ppm. <br />3 Percent of samples exceeding standard. <br />4 The [EPA recently revised the 4 -hour PIVI2_5tandard from 65 pg/m3 to 35 glrTl.
