<br /> <br />Page 60 of 65 <br /> <br />The Supplemental EIR air quality analysis would evaluate whether the proposed Specific Plan <br />Update land use changes would have the potential to result in a new or substantially more <br />severe significant air quality impact beyond that considered in the certified EIR. Consistent with <br />the certified Specific Plan EIR, the updated analysis would be based on the BAAQMD’s CEQA <br />Thresholds of Significance for Plan level documents. MIG would evaluate the proposed change <br />in land use within the Specific Plan area for consistency with the latest BAAQMD air quality <br />plan, the 2017 Clean Air Plan, by comparing anticipated vehicle miles traveled (VMT) and <br />population growth estimates, and by evaluating Specific Plan policies and components for <br />consistency with the 2017 Clean Air Plan’s control measures. The Supplemental EIR would also <br />evaluate the potential for the change in land use(s) to result in new or substantially more severe <br />significant air quality impacts from construction emissions, long-term exposure of receptors to <br />toxic air contaminants (TACs), and odors. The Supplemental EIR would qualitatively update <br />these analyses, including TAC screening distances to reflect the proposed development cap <br />increase. <br /> <br />Greenhouse Gas Emissions, Global Climate Change, and Energy <br />The Supplemental EIR greenhouse gas (GHG) analysis would describe any changes to the <br />existing GHG setting in the Specific Plan area and vicinity, to the GHG regulations potentially <br />applicable to updated Specific Plan, and to General Plan, Climate Action Plan, and Specific <br />Plan policies and components intended to reduce GHG emissions during Plan implementation. <br />The GHG analysis would evaluate whether the proposed change in Specific Plan land use <br />would have the potential to result in a new or substantially more severe significant GHG impact <br />beyond that considered in the certified EIR. The Supplemental EIR would include updated <br />California Emissions Estimator Model (CalEEMod) GHG emissions estimates based on current <br />modeling guidance for area, energy, and water GHG sources, updated land use development <br />capacities, and updated trip generation rates and travel distances from the transportation <br />analysis prepared for the Specific Plan Update. <br /> <br />“Energy” is a relatively new category in CEQA Guidelines Appendix G (effective December 28, <br />2018). The Supplemental EIR energy analysis will evaluate the potential for the updated <br />Specific Plan to result in impacts on energy resources such as diesel and gasoline fuel, <br />electricity, and natural gas. The analysis would include brief environmental and regulatory <br />setting discussions that place energy resources in the appropriate context, quantify the updated <br />Plan’s net change in energy efficiency and total energy consumption (using information from the <br />air quality emissions estimates and modeling), and evaluate whether implementation of the <br />updated Plan would result in the wasteful, inefficient, or unnecessary consumption of energy <br />resources. The analysis would document the energy- saving Specific Plan site design <br />components and policies (e.g., site planning standards, proximity to regional arterials), building <br />design standards (energy-efficient building materials and systems), and operating <br />characteristics (e.g., trip-reducing and other energy-saving operations) that result in the efficient <br />use of available energy resources. <br />Docusign Envelope ID: 885601F4-01B5-4FAB-A341-08EBC29876AA
