As demonstrated above, the Project's service population efficiency value, as estimated by the EA's provided net annual GHG emission estimates and SP, exceeds the SCAQMD 2035 efficiency target of 3.0 MT CO2e/SP/year, indicating a potentially significant impact not previously identified or addressed by the EA. As a result, the EA's less -than -significant GHG impact conclusion should not be relied upon. Thus, pursuant to CEQA Guidelines § 15183, an EIR should be prepared, including an updated GHG analysis and incorporating additional mitigation measures to reduce the Project's GHG emissions to less -than - significant levels. Mitigation Feasible Miligalion Measures Available lo Reduce F'rylissiOris Our analysis demonstrates that the Project would result in potentially significant health risk and GHG impacts that should be mitigated further. In an effort to reduce the Project's emissions, we identified several mitigation measures that are applicable to the proposed Project. Feasible mitigation measures can be found in the Department of Justice Warehouse Project Best Practices document.22 Therefore, to reduce the Project's emissions, consideration of the following measures should be made: • Requiring off -road construction equipment to be zero -emission, where available, and all diesel - fueled off -road construction equipment, to be equipped with CARB Tier IV -compliant engines or better, and including this requirement in applicable bid documents, purchase orders, and contracts, with successful contractors demonstrating the ability to supply the compliant construction equipment for use prior to any ground -disturbing and construction activities. • Prohibiting off -road diesel -powered equipment from being in the "on" position for more than 10 hours per day. • Requiring on -road heavy-duty haul trucks to be model year 2010 or newer if diesel -fueled. • Providing electrical hook ups to the power grid, rather than use of diesel -fueled generators, for electric construction tools, such as saws, drills and compressors, and using electric tools whenever feasible. • Limiting the amount of daily grading disturbance area. • Prohibiting grading on days with an Air Quality Index forecast of greater than 100 for particulates or ozone for the project area. • Forbidding idling of heavy equipment for more than two minutes. • Keeping onsite and furnishing to the lead agency or other regulators upon request, all equipment maintenance records and data sheets, including design specifications and emission control tier classifications. • Conducting an on -site inspection to verify compliance with construction mitigation and to identify other opportunities to further reduce construction impacts. • Using paints, architectural coatings, and industrial maintenance coatings that have volatile organic compound levels of less than 10 g/L. 22 "Warehouse Projects: Best Practices and Mitigation Measures to Comply with the California Environmental Quality Act."
