San Joaquin Valley Air Pollution Control District Page 3 District Reference No. 20210763 August 31,2021 recommends the County advise the project proponent to utilize electric or zero emission off-road and on-road equipment used on-site for this Project. 1 e) Health Risk Screening/Assessment The Project is located in an industrial area with other existing buildings adjacent to the Project location. However, the Project is also surrounded by multiple sensitive receptors such as single family residential units (SFR). Specifically, there is a SFR units 0.25 miles west of the Project location, SFR units located 0.33 miles east of the Project location, and a SFR unit located 0.3 miles south of the Project location. The Health Risk Assessment should evaluate the risk associated with sensitive receptors in the area and mitigate any potentially significant risk to help limit emission exposure to sensitive receptors. A Health Risk Screening/Assessment identifies potential Toxic Air Contaminants (TACs) impact on surrounding sensitive receptors such as hospitals, daycare centers, schools, work-sites, and residences. TACs are air pollutants identified by the Office of Environmental Health Hazard Assessment/California Air Resources Board (OEHHA/CARB) that pose a present or potential hazard to human health. A common source of TACs can be attributed to diesel exhaust emitted from both mobile and stationary sources. List of TACs identified by OEHHA/CARB can be found at: https://ww2.arb.ca.gov/resources/documents/carb-identified-toxic-air- contaminants The District recommends the development project(s) be evaluated for potential health impacts to surrounding receptors (on-site and off-site) resulting from operational and multi-year construction TAC emissions. i) The District recommends conducting a screening analysis that includes all sources of emissions. A screening analysis is used to identify projects which may have a significant health impact. A prioritization, using the latest approved California Air Pollution Control Officer's Association (CAPCOA) methodology, is the recommended screening method. A prioritization score of 10 or greater is considered to be significant and a refined Health Risk Assessment (HRA) should be performed. For your convenience, the District's prioritization calculator can be found at: http:www.valleyair.org/busind/pto/emission facto rs/Crite ria/Toxics/Utilities/P RIORITIZATION%20RM R%202016.XLS. ii) The District recommends a refined HRA for development projects that result in a prioritization score of 10 or greater. Prior to performing an HRA, it is recommended that development project applicants contact the District to
