Meeting Notes

On Thursday October 5, 2006 EPA joined by Chuck Peck spoke with Diana
Graham concerning the following questions Ms. Graham had regarding
information in the PPO RED: 1) How is the no-stack scenario relevant to
a railcar, truck, or ship where the fumigant vents through a smaller
opening compared to the surface area used in the calculation?  Is there
a way the model can be run to reflect a smaller surface area for
ventilation?  2)  What are the temperature limitations of the PERFUM
model? The 99% scrubber efficiency required by facilities was also
discussed.
