Barge Emissions Study - Memphis22History June 2006Southwind Field Study Conducted in conjunction with EPA (Headquarters, Region IV and Region VI), Tennessee Department of Environment and Conservation (TDEC), Arkansas Department of Environmental Quality (ADEQ), and local industry.Used a Hawk forward-looking infrared (FLIR) camera attached to a helicopter and two hand-held FLIR cameras (on the ground) to examine, and possibly discover new VOC sources in the area.Barge Emissions Study - Memphis3

Uncontrolled emissions from a tank barge observed using the FLIR camera in 2006.3PurposeIn April 2007 the SCHD Applied and received an EPA $230,000 competitive grant to begin the process of quantifying emissions from Tank Barges.

The resulting Barge Emissions Study (BES) provides an analysis of the volatile organic compounds (VOCs) and speciated air toxic emissions from tank barges carrying petrochemicals. This provides for a better understanding of this source of emissions for emissions inventories, possible risk assessment, and modeling.

A total of 44 SUMMA canisters were collected and analyzed during the BES Memphis.Barge Emissions Study - Memphis5

5Measurement MethodsFLIR GasFindIR Camera

The forward- looking infrared camera (FLIR) has a nominal spectral range of 15.4 m and uses a 30 x 30 m InSb detector with a 320 x 240 pixel array.Barge Emissions Study - Memphis6

Traffic was not recorded on September 28 or September 29 as prevailing winds were not favorable for OTM-10 measurements.Breakdown of traffic events observed at Presidents Island during OTM-10 (FTIR) Measurements18Are Voluntary Emission Reductions Working? The number of barges noted with uncontrolled emissions, during the 2009 study using the FLIR camera, certainly appear to be reduced over those observed with uncontrolled emissions, during the 2006 study. Although the FLIR camera provides qualitative data, voluntary measures (Best Work Practices) certainly appear to be influencing emissions. Barge Emissions Study - Memphis19

19Are the Emissions From Tank Barges Potentially Significant? Examining the October 8, 2009 event, the emissions appear to be 1.9 g/s (average). If this source was a stationary source the potential to emit (PTE), which is used in stationary source permitting, would be equal to approximately 66 tons/year of volatile organic compound emissions while transporting materials for this specific tank barge. 20

Barge Emissions Study - Memphis20Next Steps and Recommendations? Discuss with stakeholders the possibility of voluntarily increasing the pressure on relief valves on new and, if determined safe, existing tank barges.Discuss with stakeholders the possibility of add-on controls, such as condensers, if determined safe.Continue to examine air toxics emissions for inventory purposes, general risk assessment, and worker exposure.
