<br /> Definitions:
<br /> gal=gallons scfm =standard cubic feet per minute PAH =Polycyclic Aromatic Hydrocarbons
<br /> gpm=gallons per minute VOC=Volatile Organic Compound acfm=actual cubic feet per minute
<br /> "F=degrees Fahrenheit ppmv=parts per million by volume GAC=Granular Activated Hydrocarbon
<br /> inHg=inches of Mercury gal=gallons
<br /> gpm=gallons per minute ATC=Authority to Construct
<br /> Notes:
<br /> a =System switched to operate in catalytic mode
<br /> b=System switched to operate in thermal mode.
<br /> -Column under heading VOC(Hexane)Removed(Ib/day) added 2Q10 to track removal rate of total VOCs.
<br /> 1 =VOC represented as Hexane(molecular weight 86.17)for VOC vapor mass removal rate calculation. Hexane was used because it was most representative of the lower carbon range
<br /> organics.
<br /> 2=System permitted under ATC number N-4878-1-1. Source test for air board. Extracted groundwater being held in onsite holding tank. System shut down following source test.
<br /> 3=System started for 24-hour collection of vapor PAH samples.
<br /> 4=System shut down following completion of vapor PAH sample collection. PAH results outside of ATC limits(no detectable PAHs in influent vapor stream);alternate ATC needed to operate.
<br /> 5=Approximately 5,840 gallons of groundwater stored in holding tank discharged to sanitary sewer.
<br /> 6=ATC Number N4878-1-2 issued 7/20/2004.System restarted.
