San Joaquin Valley Air Pollution Contra!District Page 4 of 8 District Reference No:20221504 November 30, 2022 A project with a significant health risk would trigger all feasible mitigation measures. The District strongly recommends that development projects that result in a significant health risk not be approved by the land use agency. The District is available to review HRA protocols and analyses. For HRA submittals please provide the following information electronically to the District for review: • HRA (AERMQD) modeling files • HARP2 files • Summary of emissions source locations, emissions rates, and emission factor calculations and methodologies. For assistance, please contact the District's Technical Services Department by: ■ E-Mailing inquiries to: hramodeler@yalleyair.org. • Calling (559) 230-5900 Recommended Measure: Development projects resulting in TAC emissions should be located an adequate distance from residential areas and other sensitive receptors in accordance to CARB's Air Quality and Land Use Handbook: A Community Health Perspective located at httosJlww3.arb.c_a_govlchlhandbook.pdf. 3) Ambient Air Quality Analysis An Ambient Air Quality Analysis (AAAA) uses air dispersion modeling to determine if emissions increases from a project will cause or contribute to a violation of State or National Ambient Air Quality Standards. The District recommends an AAAA be performed for the Project if emissions exceed 100 pounds per day of any pollutant. An acceptable analysis would include emissions from both project-specific permitted and non-permitted equipment and activities. The District recommends consultation with District staff to determine the appropriate model and input data to use in the analysis. Specific information for assessing significance, including screening tools and modeling guidance, is available online at the District's website: www.va Ileyair.orglcega. 4) Voluntary Emission Reduction Agreement Criteria pollutant emissions may result in emissions exceeding the District's significance thresholds, potentially resulting in a significant impact on air quality.
