REV: 07-15-2021 VR Pollutants to be assessed include reactive organic gases, oxides of nitrogen, carbon monoxide, particulate matter, fine particulate matter, and carbon dioxide equivalents in metric tons (MTCO2e). This task includes one round of comprehensive emissions modeling. The GHG impact analysis will address the Project’s build-out year and a long-term horizon consistent with the City’s General Plan time frame from its adoption date. The analysis will incorporate compliance with the City’s Standard Conditions of Approvals for Air Quality. The greenhouse gas analysis will provide a discussion of 2050 emissions and the progress towards the Executive Order S-3-05 goal. The City’s Climate Action Plan (CAP), BAAQMD’s 2030 and 2050 Greenhouse Gas Reduction Goals and its 2017 Clean Air Plan will be used to determine the Project’s consistency with applicable state and local plans for greenhouse gases. Health Risk Assessment. As an office project the Project would not be considered a sensitive land use. The Project is not located within 1,000 feet of sensitive receptors and is not a land use of concern (sour of toxic air contaminants) (BAAQMD 2017, CARB 2005), therefore, a qualitative assessment of health risks will be prepared. Odors. The Project is not considered a sensitive receptor and is also not a source of potential odors according to BAAQMD’s guidance for siting land uses with respect to odors. Consultant will qualitatively address odor impacts relative to BAAQMD’s guidance. Energy. Consultant will determine potential energy use of the Project and the potential increases associated with the implementation of the Project, consistent with modeling conducted for air quality and greenhouse gas emissions. The City’s General Plan and Climate Action Plan will be important to inform the analysis of whether the Project results in wasteful or inefficient use of energy. Emissions Reductions and Significance Findings. If deemed necessary, mitigation measures will be identified to reduce significant impacts related to air constituents and GHG emissions. Emissions reductions from these measures will be quantified. Deliverable A word version of the AQ/GHG/Energy Assumptions The Air Quality, Greenhouse Gas, and Energy Technical Memorandum of Assumptions and Methodology included as an appendix to the CEQA document. Assumptions The analysis will be provided in a stand-alone technical memorandum including emissions modeling methodology and assumptions, as well as model output and response to the Appendix G checklist questions for air quality, greenhouse gases, and energy. Consultant will provide the City with the modeling assumptions for review and comment prior to initiating the comprehensive modeling. The schedule clock will be paused during the review period and will begin upon receipt of acceptance. CalEEMod will be used to estimate criteria air pollutant and GHG emissions. If CalEEMod is updated and the update precipitates revised modeling a budget augment will be warranted. The criteria air pollutant/greenhouse gas modeling includes one round of comprehensive modeling. Based on the Project Description, this scope includes 12 hours of modeling. If the level of effort exceeds the estimated number of hours a budget augment may be requested. ATTY/AGR.2021/Amend No. 1/Stantec Consulting Services, Inc. (Page 12 of 21)
