Table 18 <br /> Apartment Soil Vapor Extraction System-Operating Data <br /> Parcel 2A-L&M OU <br /> 666 West Weber Avenue,Stockton,CA <br /> Definitions: <br /> °F =Degrees Fahrenheit VOC =Volatile Organic Compounds <br /> inHg =Inches of mercury ppmv=Parts per million by volume <br /> acfm =Actual cubic feet per minute SJAVOCD =San Joaquin Valley Air Pollution Control District <br /> scfm =Standard cubic feet per minute ATC =Authority to Construct <br /> [ ] =Indicates reference to equation <br /> FID =Flame Ionization Detector <br /> Notes: <br /> -Column under heading VOC(Hexane)Removed(Ib/day) added 2Q10 to track removal rate of total VOCs. <br /> a =VOC reported as Hexane(molecular weight 86.17)for VOC vapor mass removal rate calculation. Hexane was used <br /> because it was most representative of the lower carbon range organics. <br /> b =System inspected by the air board and started on 5/31/2007. <br /> c=Vapor flow data collected as SCFM. <br /> d =Flow rate(acfm)derived from Roots 56 curve with temperature being the average for the system. <br /> e =Flame Out <br /> f=System switched to operate in catalytic mode. <br /> g =Hourmeter malfunction.ASVE hours estimated based on L&M OU SVE system runtime. <br /> h =New hourmeter installed on 4/13/11 <br /> Equations: <br /> VOC Removed/day= <br /> [Avg of consecutive(Inf-Eff)Conc(ppmv)/1,000,000]X[86.17(g/mole)]X[1 lbs/453.59 g]X[1.2641 moles/1 cf]X[Avg of consecutive flow rates(scfm)]X[60 min/hr]X[24 hr/day] <br /> Permits: <br /> Air emissions are permitted under SJVAPCD ATC Number N-4878-2-0. <br /> I:\Tidewater\TW Stockton(P2A)\Engineering\O&M\Tables\O&M Tables 201 1\3Q1 1\Parcel 2A OM Tables 3Q11.xlsx Page 2 of 2 <br />
