1P <br /> 41 <br /> 11 Draft Supplemental Environmental Impact Report Page IV.D-14 <br /> Forward Inc. Landfill 2018 Revised Project <br /> • The SJVAPCD signed a Memorandum of Understanding to implement CARB's Landfill <br /> • Methane Rule on October 20, 2011. <br /> • BPS would be established through a process approved by the District's Governing Board. The <br /> • proposed process would provide ample opportunity for stakeholders and other interested <br /> parties to participate and provide valuable input into the establishment of baseline GHG <br /> emissions and BPS. <br /> Existing Air Quality <br /> The SJVAPCD's regional air quality monitoring network provides information on existing <br /> • ambient concentrations of criteria air pollutants. Monitored ambient air pollutant <br /> concentrations reflect the number and strength of emissions sources and the influence of <br /> topographical and meteorological factors. Table IV.D-2 presents a five-year summary of air <br /> • pollutant (concentration) data collected at the monitoring station in the vicinity of the project <br /> • area on Hazelton Street in Stockton,located seven miles to the northwest of the Forward <br /> Landfill. Pollutant concentrations measured at this station should be representative of <br /> background air pollutant concentrations at the project site. However,background <br /> concentrations can vary among different locations within an area. Table IV.D-2 compares these <br /> measured air pollutant concentrations with CAAQS and NAAQS. The monitoring data show <br /> that ozone, PM,o, and PM2,5 periodically exceeded the AAQS. <br /> Table IV.D-2: Air Quality Data Summary (2012-2016) For the Project Area' <br /> Monitoring Data by Year <br /> Pollutant CAAQS/ <br /> _ _ <br /> NAAQSZ 2012 2013 2014 2015 2016 <br /> • Ozone <br /> • Highest 1-Hour Average (ppm)' 0.09/- 0.097 0.080 0.090 0.094 0.102 <br /> Days of Exceedance 1 0 0 0 2 <br /> Highest 8-Hour Average (ppm)' 0.070/0.070 0.083 0.067 0.077 0.078 0.078 <br /> Days of Exceedance 5 0 4 2 2 <br /> Particulate Matter(PMI,) <br /> • Highest 24-Hour Average(µg/m3) <br /> 50/150 70.0 95.5 94.0 55.3 66.5 <br /> • Estimated Days of Exceedance 17.9 58.2 18.0 24.5 30.6 <br /> Annual Average(Mg/ml)3 20/- 22.8 32.0 24.5 28.0 26.5 <br /> Particulate Matter(PM,$) <br /> Highest 24-HourAverage(µg/m3)3 -/35 60.4 66.5 56.8 58.8 43.7 <br /> Days of Exceedance 6.0 27.6 16.0 12.2 4.0 <br /> • Annual Average(pg/ml)3 12/15 12.4 NA 12.3 12.3 NA <br /> • SOURCE:GARB Air Quality Data Statisticstl(_it�://wwwarb.ca.ym_v/adam/welmmehtrnl),2012-2016. <br /> .
