Sequoia Ecological Consulting, Inc. CalVTP Project-Specific Analysis and Addendum Augustin Bernal Community Park Fuel Reduction November 2025 4-13 4.3.1.3. Impact AQ-3 This impact does not apply to the treatment project because no NOA, ultramafic rock outcrops, serpentine soils, or former asbestos mines are mapped in or near the treatment area, and no serpentine soils or serpentine outcrops were observed during biological reconnaissance surveys (USGS 2011, 2017; Sequoia 2025). 4.3.1.4. Impact AQ-4 Prescribed burning during initial and maintenance treatments could expose people to toxic air contaminants. The potential to expose people to toxic air contaminants from prescribed burning was examined in the PEIR and found to be potentially significant because such burns release smoke containing fine particulate matter and other harmful compounds that can affect respiratory and cardiovascular health, especially in areas near sensitive populations or regions already experiencing poor air quality. The duration and parameters of the prescribed burns are within the scope of the activities addressed in the PEIR, and within the BAAB, air quality conditions are consistent with those analyzed in the PEIR for Alameda County and Pleasanton. Therefore, the potential for exposure to toxic air contaminants is also within the scope of the PEIR. SPRs applicable to these treatment activities are AD-4, AQ -1, AQ -2, AQ -3, and AQ-6. All feasible measures to prevent and minimize smoke emissions, as well as exposure to smoke, are included in SPRs; however, this impact would remain significant and unavoidable, as explained in the PEIR. The inclusion of approximately 93 acres of land that is outside the CalVTP treatable landscape in the proposed treatment area constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the air quality conditions present and air basin in the areas outside the treatable landscape are essentially the same as those within the treatable landscape. Therefore, the air quality impact is also the same, as described above. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. 4.3.1.5. Impact AQ-5 The use of vehicles and mechanical equipment during initial and maintenance treatments could expose people to objectionable odors from diesel exhaust. The PEIR determined that the potential for exposing individuals to diesel exhaust odors is less than significant, as these odors are typically short-lived, confined to specific areas, and classified as nuisance pollutants rather than health risks. Additionally, treatment activities are brief and spread out, reducing the likelihood of sustained exposure near sensitive locations. This impact is within the scope of the PEIR because the exposure potential and the proposed activities, as well as the associated equipment and duration of use, are consistent with those analyzed in the PEIR.
