Draft Supplemental Environmental Impact Report Page IV.D-19 Forward Inc. Landfill 2014 Expansion Project Project(Flare)-Current Actual 256.4 253.0 237.7 237.7 22.6 46.7 _ Project(LFG Engines)-Current Actual 271.3 478.8 243.4 243.4 49.4 64.3 CEQA Threshold 10 100 15 15 27 10 Exceeds Threshold Yes Yes Yes Yes Yes Yes SOURCE: SCS Engineers,2014 NOTES:All CEQA significance thresholds listed are from The SJVAPCD's GAMAQI(April,2012). See Tables ES-2 through ES-8,3-6A,3-613,3-7A,and 3-7B of the AQIA for more information.ES-2 through ES-7 provide the emissions associated with the current actual,current permitted,future potential(flares),and future potential(LEG engines), current actual vs.future potential,and current permitted vs.future potential,while Table ES-8 provides the net project _ emissions(without adding in the offsite mobile sources).Off-site mobile source emissions are provided in AQIA Table 3-14. Mobile source emissions based on a project rate of 620 haul trips per day,311 operational days per year,and 8,668 tons per day of waste acceptance:same as current permitted levels,but higher than actual baseline(212 haul trips per day and 3,500 tons per day of waste acceptance).Fugitive dust emissions are based on vehicle traffic on unpaved roads and surfaces.See _ AQIA Tables 3-5A,and 3-5B for details on mobile and fugitive dust emission calculations. Rule 2201 requires new and modified stationary sources of emissions to mitigate emissions using best available control technology and to offset emissions when above thresholds. All VOCs, CO, NOx, SOx, PM10 and PM2.5 emissions from stationary sources in excess of the applicable SJVAPCD threshold shall be offset by acquisition of emission offsets, as required by SJVAPCD Rule 2201 regulations. For example, under the Project (flare) -Current Actual scenario, a total of 22.0 tpy of NOx emissions would be offset (32.0 tpy- 10 tpy);while under the Project(LFG Engines)-Current Actual scenario, a total of 36.9 tpy of NOx emissions would be offset(46.9 tpy- 10 tpy). Thus, the stationary source NOx emissions would be mitigated with emission offsets and would be less than significant. _ Mitigation Measure D.2a. (Revises 2013 EIR Mitigation Measure D.2a.): The applicant shall comply with SJVAPCD Rule 2201 regulations to offset stationary source emissions of _ VOCs, CO, NO, SOX, PM10 and PM2.5 in excess of the applicable SJVAPCD thresholds. The applicant shall also comply with Regulation VIII and implement Mitigation Measure D.1 for operational activities such as earthmoving. Mitigation Measure D.2b. (Same as 2013 EIR Mitigation Measure D.2b.): The applicant shall enter into a Voluntary Emissions Reduction Agreement(VERA) with the SJVAPCD (to offset unmitigated mobile and fugitive emission impacts). The VERA shall cover _ increases in mobile and fugitive emissions(above the CEQA thresholds for NOx, PM10 and PM2.5) associated with the 8.0 mcy of new capacity. With implementation of Mitigation Measures D.2a and D.2b, stationary sources would be — mitigated (by D.2a) and project fugitive emissions and mobile emissions over the CEQA thresholds would be mitigated by the VERA. Impact D.3. Odor and Visible Dust Impacts (Same as 2013 EIR Impact D.4.) As bacterial decomposition proceeds, odoriferous compounds can escape from the _ landfill surface through cracks in the surface cover. Other possible sources of odors are the actual wastes. Some household and consumer products contain substances with distinctive odors. The major contribution to odors comes from two groups of compounds: the first group is dominated by esters and organosulfurs, and the second group consists of alkyl benzenes and limonene.
