Draft Supplemental Environmental Impact Report Page IV.D-18 Forward Inc. Landfill 2014 Expansion Project Impact D.2. The project would result in an increase in operational emissions of criteria air pollutants from onsite emission sources and increase emissions associated with traffic-related trips (Revises 2013 EIR Impact D.2. and adds CO discussion to replace 2013 EIR Impact 13.3.). The Air Quality Impact Assessment(AQIA)"evaluated how the project would increase criteria pollutant emissions from LFG-derived sources under two scenarios: additional LFG is controlled either by additional flare capacity(flare scenario) or LFG engines at existing and future LFG to energy facilities (LFG engine scenario). Two Baseline Lscenarios were evaluated: Current Actual emissions, determined using 2012 and 2013 operational data; and Current Permitted emissions,based on emissions of landfill sources at maximum permitted levels. �• Table IV.D-4 presents net project emissions derived from the AQIA. Project unmitigated impacts for VOC, NO, PM10,PM2.5and CO would be considered potentially significant under almost all of the Project scenarios presented. Additional information regarding the ` assumptions and methodologies used in the air emission calculations is available in the AQIA by SCS Engineers (See Appendix F). The flare scenario would result in lower emission increases of VOC, CO, NO., SO, PM10 and PM2_5compared to the LFG engine scenario.
