Sequoia Ecological Consulting, Inc. CalVTP Project-Specific Analysis and Addendum Augustin Bernal Community Park Fuel Reduction November 2025 4-11 4.3.1. Discussion 4.3.1.1. Impact AQ-1 The use of vehicles, mechanical equipment, prescribed herbivory, herbicides, and prescribed burning during initial and maintenance treatments would result in emissions of criteria pollutants that could exceed CAAQS or NAAQS thresholds for the San Francisco Bay Area Air Basin. The potential for emissions of criteria pollutants to exceed CAAQS or NAAQS thresholds was examined in the PEIR and was found to be potentially significant because treatment activities could generate pollutants—such as particulate matter, ozone precursors, or nitrogen oxides—in quantities that might surpass regulatory limits, especially in areas already designated as nonattainment for one or more pollutants. Emissions of criteria air pollutants related to the proposed treatment are within the scope of the PEIR because the associated equipment and duration of use are consistent with those analyzed in the PEIR. The SPRs applicable to this treatment project are AD-1, AD-4, AQ-1 through AQ-4, and AQ-6, which require public notification for prescribed burning; compliance with applicable BAAD air quality requirements; submittal of an SMP and Burn Plan if the prescribed burning triggers the threshold (17 CCR Section 80160); minimizing dust; and following all safety procedures required of a CAL FIRE crew. SPR AQ-5 would not apply because no NOA, ultramafic rock outcrops, or former asbestos mines are mapped in or near the treatment area (USGS 2011, 2017). Additionally, the City would implement the emission reduction techniques included in MM AQ-1 to the extent feasible. However, because the treatments would be implemented by a public agency with limited funding, procuring or paying additional amounts for contractors that use equipment meeting the latest efficiency standards, including meeting USEPA’s Tier 4 emission standards, using renewable diesel fuel, using electric- and gasoline-powered equipment, and using equipment with Best Available Control Technology may be cost-prohibitive. Carpooling would be encouraged by the City, but because crews may not all be employed with the same company, carpooling may not be feasible to implement for most of the workers. The City would document the extent the agency and/or its contractors are able to implement MM AQ -1. Renewable diesel would be used by the City and/or its contractors to the extent required by state regulations. For these reasons, and as explained in the PEIR, this impact would remain significant and unavoidable. In addition to the CalVTP PEIR SPRs and MMs, additional project-specific measures are described below each applicable measure. • MM AQ-1: Implement On-Road Vehicle and Off-Road Equipment Exhaust Emission Reduction Techniques The City would document the extent that it and/or its contractors are able to implement MM AQ-1 by documenting each unit’s certified engine tier specification and applicable CARB fleet regulation compliance certificates prior to mobilization. This information would be compiled in an annual monitoring
