<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 />oF = 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 (lb/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 N-4878-1-2 issued 7/20/2004. System restarted.
<br />7 = Source test for air board. System shut down following source test due to on-site excavation activities.
<br />8 = Samples collected from wastewater treatment system. Carbon change-out needed.
<br />9 = System shut down following completion of vapor PAH sample collection.
<br />10 = System non-operational since 5/2005. No sampling and no discharge activities occurred.
<br />11 = System effluent sampled on 7/6/2005 following startup.
<br />12 = Start-up on fresh GAC
<br />13 = pH measurement recorded in the field beginning December 9, 2009.
<br />14 = Hourmeter and totalizer readings recorded on Feb 4, 2010, all else occurred on Feb 5, 2010.
<br />15 = System shut down on August 28, 2010 due to the failure of the oil-water seperator transfer pump. Repairs were made and the system was restarted on October 4, 2010.

<br />= System shut down with regulatory approval for remainder of 4Q11 due to declining influent concentrations. Will be restarted during 1Q12 for rebound testing.
<br />= System hour meter was replaced. DPE wells were closed during pilot test conducted from 11/16/10 to 11/19/10. No well field temperature or flow rate were collected; therefore, values from the most recent visit with the same
<br />system vacuum was used instead (07/12/10).
