District CEQA Reference No. 20180683 Page 2 of 4 <br /> the current SEIR is to (1) replace the 2014 project's Draft Supplemental EIR, and (2) is <br /> being developed for the current proposed landfill project. <br /> The environmental issues to be discussed in the SEIR include (1) Air Quality/Odors and <br /> (2) Climate Change. The District offers the following comments: <br /> 1. The SEIR should consider the following.- <br /> a) <br /> ollowing:a) Criteria Pollutants: Project related criteria pollutant emissions should be identified <br /> and quantified. The discussion should include existing and post-project <br /> emissions. <br /> �J <br /> i. Construction Emissions: Construction emissions are short-term emissions <br /> and should be evaluated separately from operational emissions. For <br /> reference, the District's annual criteria thresholds of significance for <br /> construction are: 100 tons per year of carbon monoxide (CO), 10 tons per <br /> year of oxides of nitrogen (NOx), 10 tons per year of reactive organic <br /> gases (ROG), 27 tons per year of oxides of sulfur (SOx), 15 tons per year <br /> of particulate matter of 10 microns or less in size (PM10), or 15 tons per <br /> year of particulate matter of 2.5 microns or less in size (PM2.5). <br /> ii. Operational Emissions: Permitted (stationary sources) and non-permitted <br /> (mobile sources) sources should be analyzed separately. For reference, <br /> the annual criteria thresholds of significance for operation of permitted and <br /> non-permitted sources each are: 100 tons per year of carbon monoxide <br /> (CO), 10 tons per year of oxides of nitrogen (NOx), 10 tons per year of <br /> reactive organic gases (ROG), 27 tons per year of oxides of sulfur (SOx), <br /> 15 tons per year of particulate matter of 10 microns or less in size (PM10), <br /> or 15 tons per year of particulate matter of 2.5 microns or less in size <br /> (PM2.5). <br /> iii. Recommended Model: Project related criteria pollutant emissions from <br /> construction and operation non-permitted (limited to equipment not subject <br /> to District permits) should be identified and quantified. Emissions analysis <br /> should be performed using CaIEEMod (California Emission Estimator <br /> Model), which uses the most recent approved version of relevant Air <br /> Resources Board (ARB) emissions models and emission factors. <br /> b) In addition to the item identified above, the SEIR should also include the <br /> following: <br /> i. A discussion of the methodology, model assumptions, inputs and results used <br /> in characterizing the Project's impact on air quality. To comply with CEQA <br />
