Sequoia Ecological Consulting, Inc. CalVTP Project-Specific Analysis and Addendum Augustin Bernal Community Park Fuel Reduction November 2025 4-79 the potential for a substantial short-term increase in SENLs, but haul trucks would only be in use during daytime hours, generally Monday through Friday, and in compliance with other more stringent local noise ordinances (see Impact NOI-1). The SENL describes a receiver’s cumulative noise exposure from a single impulsive noise event (e.g., an automobile passing by or an aircraft flying overhead), which is defined as an acoustic event of short duration and involves a change in sound pressure above some reference value. The impacts are within the scope of the PEIR because the treatment activities and methods are the same as those analyzed in the PEIR. SPRs applicable to this treatment are AD-3, NOI-1, NOI-2, NOI-3, NOI-4, NOI- 5, and NOI-6, described under Impact NOI-1. The potential for a substantial short-term increase in SENL during the project treatments was evaluated in the PEIR and was found to be less than significant with the implementation of these SPRs. 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. As described in Impact NOI-1, the northernmost portion of the Project is further from the treatable landscape than other portions of the Project. For much of the Project area, the existing roadway network and access roads used by the worker vehicles and trucks for hauling would be the same to reach the treatable landscape inside the CalVTP as outside the CalVTP. For portions of the project area that are further from CalVTP treatable landscape areas, like the northernmost portion, the types of sensitive receptors located along existing roads and access roads would be the same as those covered in the PEIR. Therefore, the noise impact is also the same as described above and would be less than significant with the application of the same SPRs. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. 4.12.1.3. New Noise Impacts The proposed treatment is consistent with the treatment types and activities discussed in the PEIR. The site-specific characteristics of the proposed treatments are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (Sections 3.13.1, Environmental Setting, and 3.13.2, Regulatory Setting, in Volume II of the Final 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, the existing environmental and regulatory conditions pertinent to noise that are present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape, as previously described. The Project is consistent with the types of projects covered in the PEIR. The local jurisdictions where the Project would occur have specific noise ordinances related to noise from animals. The potential for animals used for herbivory treatments to violate local noise ordinances for animals was not specifically addressed in the PEIR but is analyzed in impact NOI-1 above. This would be considered a
