Comment on Garry Avenue Business Park Project <br />Planning Commission Agenda Item 2 (Amendment Application No. 2022 -01; Conditional Use Permit No. 2022-14) <br />October 10, 2022 <br />Page 6 of 7 <br /> <br /> <br />SWAPE analyzed the Project’s emissions of Diesel Particulate Matter (DPM) into the air, <br />and the resulting impact on human health. To do so, SWAPE prepared a screening-level Health <br />Risk Assessment (“HRA”) to evaluate potential impacts from the construction and operation of <br />the Project. (Exhibit A, pp. 3-7.) SWAPE prepared a screening-level HRA to evaluate potential <br />health risk impacts posed to residential sensitive receptors as a result of the Project’s <br />construction-related and operational TAC emissions. SWAPE used AERSCREEN, the leading <br />screening-level air quality dispersion model. SWAPE applied a sensitive receptor distance of 200 <br />meters and analyzed impacts to individuals at different stages of life based on OEHHA and <br />SCAQMD guidance utilizing age sensitivity factors. <br /> <br />SWAPE found that the excess cancer risks at a sensitive receptor located approximately <br />200 meters away over the course of Project construction and operation, while utilizing the <br />recommended age sensitivity factors, are approximately 71.6 in one million for infants, 103 in <br />one million for children, and 11.5 in one million for adults. (Id., p. 6.) Moreover, the excess <br />cancer risk over the course of a residential lifetime (i.e. 30 years) for Project operation and <br />construction is approximately 188 in one million. (Id.) The cancer risks to infants, children, <br />adults, and lifetime residents appreciably exceed SCAQMD’s threshold of 10 in one million, <br />thus indicating a significant air quality impact. <br /> <br />Because the Project will have numerous significant air quality impacts peculiar to this <br />project, and not analyzed in the GP EIR, additional CEQA review is required. <br /> <br />C. The Project Will Have Significant Greenhouse Gas Impacts Requiring <br />Additional CEQA Analysis Under 15183 Exemption. <br /> <br /> SWAPE analyzed Project’s potential greenhouse gas (“GHG”) emissions and found that <br />the Project and GPU EIR failed to adequately analyze the Project’s greenhouse gas impacts, <br />which SWAPE found to be potentially significant. (See, Exhibit A, pp. 8-10.) <br /> <br />First, the Exemption Checklist’s greenhouse gas impact analysis and subsequent less- <br />than-significant impact conclusion are based on an outdated quantitative analysis GHG <br />threshold. (See, id., pp. 8-9.) According to SWAPE, the Exemption Checklist incorrectly <br />“estimates that the Project would generate net annual [GHG] emissions of 1,668 metric tons of <br />carbon dioxide equivalents per year (“MT CO2e/year”), which would not exceed the SCAQMD <br />threshold of 3,000 MT CO2e/year.” (Id., p. 8.) SWAPE explains that this is incorrect because <br />“the guidance that provided the 3,000 MT CO2e/year threshold, the SCAQMD’s 2008 Interim <br />CEQA GHG Significance Threshold for Stationary Sources, Rules, and Plans report, was <br />developed when the Global Warming Solutions Act of 2006, commonly known as “AB 32”, was <br />the governing statute for GHG reductions in California. AB 32 requires California to reduce <br />GHG emissions to 1990 levels by 2020.” (Id.) In addition, the Association of Environmental <br />Professionals (AEP) guidance states: <br />
