benzene saturation unit

Murphy Oil USA, Inc. submitted a significant modification application for The Meraux Refinery Title V/Part 70 air quality permit on February 25, 2009 in Vol. 1 and  Vol. 2. The application is to construct and operate a benzene saturation unit to produce low benzene gasoline products.  The proposed pollution permit seeks to use gasoline tanks with fixed roof(s), to route the "BenFree Unit" (BFU) to an inadequate gas recovery system, and to route H2S rich vent streams to the flare. To protect public health and safety, Louisiana DEQ must require stringent application of the best available controls to achieve the lowest emissions into the air we breathe.

The minimum minor modification fee was assessed, since there was no increase in the capacity at the facility.
Additionally, an air toxins surcharge was applied to the permit fee, since some emission rates will increase by an amount greater than the regulatory minimum emission rate for known carcinogens, human reproductive toxins, or known and probable carcinogens.
