PUBLIC NOTICE
LOUISIANA DEPARTMENT OF ENVIRONMENTAL QUALITY (LDEQ)
CHALMETTE REFINING, L.L.C / CHALMETTE REFINERY
FLUIDIZED CATALYTIC CRACKING & ALKYLATION UNITS
 
PUBLIC HEARING AND REQUEST FOR PUBLIC COMMENT 
ON PROPOSED PART 70 AIR OPERATING & PREVENTION OF SIGNIFICANT DETERIORATION (PSD) PERMIT MODIFICATIONS 
& THE ASSOCIATED ENVIRONMENTAL ASSESSMENT STATEMENT
 
The LDEQ, Office of Environmental Services, will conduct a public hearing to receive comments on the proposed Part 70 air operating & Prevention of Significant Deterioration (PSD) permit modifications and the associated Environmental Assessment Statement (EAS) for Chalmette Refining, L.L.C, P.O. Box 1007, Chalmette, LA 70044 for the Fluidized Catalytic Cracking and Alkylation Units. The facility is located at 500 West St. Bernard Hwy, on the left descending bank of the Mississippi River at Mile 89 above Head-of-Passes in Chalmette, St. Bernard Parish.
 
The hearing will be held on Thursday, September 27, 2007, beginning at 6:00 p.m., at the Big Tent in St. Bernard Parish Council, 8201 West Judge Perez Drive, Chalmette, LA..  During the hearing, all interested persons will have an opportunity to comment on the proposed permit.
 
Chalmette Refining, L.L.C, is a joint venture between ExxonMobil Corporation and Petroleus de Venezuela, the Venezuelan National Oil Company. Chalmette Refinery is an integrated crude operation (high conversion) which includes crude distillation, catalytic reforming, fluid catalytic cracking (FCC), hydrocracking, hydrogen fluoride (HF) Alkylation, delayed coking, and aromatics processing units. The refinery is capable of producing gasoline, diesel, benzene/toluene/xylene (BTX), distillates and elemental sulfur (sulfur recovery); as well as by-products such as petroleum coke and liquefied petroleum gases (LPG).
 
Chalmette Refining, L.L.C, Chalmette Refinery  requested a permit modification to the existing Part 70 Permit No. 3022-V0 and the PSD Permit No. PSD-LA-199(M-5) both dated January 30, 2007. The facility proposes to undertake Thermal De-NOx Project as per the requirements of U.S. EPA Consent Decree, a NSR Global Settlement (Civil Action No. 05-4662 B(i)) between U.S. EPA and State of Louisiana verses Chalmette Refining, L.L.C filed on April 26, 2006, to reduce NOx emissions from the FCC Unit. The project will substantially decrease NOx emissions but there will be an increase in the CO emissions (collateral increase) greater than the PSD significance level of 100 tons per year as shown below; therefore, netting is required.


 
The Thermal De-NOx Project emissions increases/decrease in tons per year is as follows:

There are no creditable contemporaneous emissions increases or decreases within the contemporaneous period since emission changes were considered in the prior PSD Permit No. PSD-LA-199(M-5) dated January 30, 2007; therefore, a PSD review is required for CO emissions from the Thermal De-NOx Project. Under the Best Available Control Technology (BACT) requirements the CO emissions will be controlled by adopting good engineering practices and operating the FCC unit in full-burn-mode. The CO emissions will be limited to less than or equal to 500 ppmv at 0% oxygen on an hourly average basis and 300 ppmv at 0% oxygen on a rolling 365-day average. PM10, SO2, NOX, and VOC emissions were less than the PSD significance levels.
 
Permitted emissions from the FCCU and Alkylation Unit based on the current operating conditions and including the Thermal De-NOx Project in tons per year are as follows:
