City of San Leandro Alvarado Commerce Center Project <br /> 42 <br />actions that may be implemented to meet the City‘s greenhouse gas reduction target of 25 percent <br />below 2005 emissions levels by 2020 (San Leandro 2009). <br />Thresholds <br />For the purposes of this analysis, the City of San Leandro has determined the GHG emissions <br />thresholds contained in the BAAQMD’s May 2017 CEQA Air Quality Guidelines are the appropriate <br />thresholds to use. As discussed under Section 3, Air Quality, the BAAQMD developed screening <br />criteria to provide lead agencies and project applicants with a conservative indication of whether a <br />project could result in potentially significant GHG impacts. If all of the screening criteria are met by a <br />project, then the lead agency or applicant would not need to perform a detailed GHG assessment of <br />their project’s GHG emissions (BAAQMD 2017b). <br />The BAAQMD’s operational GHG screening level for warehouse land uses is 64,000 square feet, for <br />general light industry is 121,000 square feet, and for manufacturing is 89,000 (BAAQMD 2017b). <br />Since the project involves almost 150,000 square feet, the project exceeds the screening level and a <br />detailed GHG assessment is required. The BAAQMD CEAQ Air Quality Guidelines has a bright line <br />threshold of 1,100 MT of CO2e per year. This threshold is based on attaining the 2020 goal for AB 32. <br />The project is expected to be operational by 2020. Therefore, BAAQMD’s May 2017 thresholds, <br />which are consistent with the AB 32 2020 targets, are considered appropriate. <br />Methodology <br />The California Emissions Estimator Model (CalEEMod) version 2016.3.1 was used to calculate the <br />total and new emissions for the project, which include construction and net new operational <br />emissions. Net new operational emissions include the project emissions minus existing onsite uses <br />emissions. This methodology is recommended by the California Air Pollution Control Officers <br />Association (CAPCOA) CEQA and Climate Change white paper (CAPCOA 2008). The analysis focuses <br />on CO2, N2O, and CH4 as these are the GHG emissions that onsite development would generate in <br />the largest quantities. Fluorinated gases, such as HFCs, PFCs, and SF6, were also considered for the <br />analysis as they are primarily associated with industrial processes. Calculations were based on the <br />methodologies discussed in the CAPCOA white paper and included the use of the California Climate <br />Action Registry (CCAR) General Reporting Protocol (CCAR 2009).Operational Emissions <br />Operational emissions for project were modeled using CalEEMod and compared to the BAAQMD <br />thresholds. CalEEMod provides operational emissions of CO2, N2O, and CH4. Emissions from energy <br />use include electricity and natural gas use. The emissions factors for natural gas combustion are <br />based on the U.S. EPA’s AP-42 (Compilation of Air Pollutant Emissions Factors) and CCAR. Electricity <br />emissions are calculated by multiplying the energy use times the carbon intensity of the utility <br />district per kilowatt hour (CAPCOA 2016). The default electricity consumption values in CalEEMod <br />include the CEC-sponsored California Commercial End Use Survey (CEUS) and Residential Appliance <br />Saturation Survey (RASS) studies. <br />Emissions associated with area sources, including consumer products, landscape maintenance, and <br />architectural coating were calculated in CalEEMod and utilize standard emission rates from CARB, <br />U.S. EPA, and emission factor values provided by the local air district (CAPCOA 2016). <br />Emissions from waste generation were also calculated in CalEEMod and are based on the IPCC’s <br />methods for quantifying GHG emissions from solid waste using the degradable organic content of <br />waste (CalEEMod User Guide 2016).
