12/16/2019 MM AIR -3.1: Prior to issuance of a grading permit, the project shall develop a plan demonstrating that the off-road equipment used on-site to construct the project would achieve a fleet -wide average 55 -percent reduction in DPM exhaust emissions or greater. The plan shall be submitted and approved by the City Planning Division. The following are feasible methods: All diesel -powered off-road equipment, larger than 25 horsepower, operating on the site for more than two days continuously shall, at a minimum, meet EPA particulate matter emissions standards for Tier 3 engines with CARB-certified Level 3 Diesel Particulate Filters or equivalent. • All diesel -powered off-road equipment, larger than 25 horsepower, operating on the site for more than two days continuously shall meet EPA Tier 4 standards for particulate matter. • The use of equipment that includes electric or alternatively fueled equipment (i.e., non -diesel) would meet the reduction requirement above. The City finds that Mitigation Measure AIR -3.1 is feasible, is adopted, and will further reduce impacts associated with this issue to a level of less than significant. Accordingly, the City finds that, pursuant to Public Resources Code section 21081(a)(1) and State CEQA Guidelines section 15091(a)(1), changes or alterations have been required in, or incorporated into, the proposed project that mitigate or avoid the potentially significant impacts of the proposed project related to this issue. Impact AIR -C: The project would result in a cumulatively considerable contribution to a significant air quality impact. Finding. The implementation of mitigation measure MM AIR -3.1 would reduce the project's cumulatively considerable contribution to a significant cumulative community risk to a less than significant level. (Less than Significant Cumulative Impact with Mitigation Incorporated). Changes or alterations have been required in, or incorporated into, the Project, which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, section 15091(a) (1).) Facts in Support of Finding. The computed cumulative community health risk with implementation of the above mitigation measure would be below the BAAQMD cumulative significance thresholds. Additionally, no single project is sufficient in size, by itself, to result in nonattainment of ambient air quality standards. Instead, a project's individual emissions contribute to existing cumulatively significant adverse air quality impact (page 42 of the Draft EIR). See MM AIR -3.1 above. The City finds that Mitigation Measure AIR -3.1 is feasible, is adopted, and will further reduce impacts associated with this issue to a level of less than significant. Accordingly, the City finds that, pursuant to Public Resources Code section 21081(a)(1) and State CEQA Guidelines section 15091(a)(1), changes or alterations have been required in, or incorporated into, the proposed project that mitigate or avoid the potentially significant impacts of the proposed project related to this issue. Biological Resources Impact BI0-1: The project would have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the CDFW or USFWS.
