4 Environmental Analysis 4.3 Air Quality an adjacent paved public roadway or the paved shoulder of a paved public roadway at the end of any workday. This rule applies to construction sites larger than 1 acre and applies to the Project during Project construction. 4.3.3 Regional and Local Air Quality Conditions 4.3.3.1 San Joaquin Valley Air Basin Attainment Status In an effort to protect human health and welfare, the CARB and USEPA have established ambient air quality standards. Areas are considered in "attainment" if standards are met and "nonattainment" if they are not met. For ozone, nonattainment status is further classified as marginal, moderate, serious, severe, or extreme. At the federal level, the SJVAB is designated as an "extreme" nonattainment area for the 8-hour ozone standard, nonattainment for PM2.5, and a maintenance area for PM,o. At the state level, the SJVAB is designated as a "severe" nonattainment area for 1-hour ozone standard, nonattainment for the 8-hour ozone standard, and nonattainment for both the PM,o and PM2.5 standards. The attainment classifications for the criteria pollutants are presented in Table 4.3-2. Table 4.3-2.

The closest and most representative monitor measuring ozone, NO2, and PM2.5 concentrations is the is the Tracey Airport monitoring station, located approximately 7 miles east of the Project area. For SO2, the closest monitor is the Fresno-Garland monitoring station, located approximately 117 miles southeast of the Project area. Finally, for CO, the Stockton Hazleton Street monitoring station is the closest, located approximately 23 miles northeast of the proposed Project. For the purposes of this analysis, these monitoring locations were considered representative of the air quality Griffith Energy Storage Project 4.3-14 Tetra Tech/SCH 2022120675 Draft Environmental Impact Report August 2023
