MERAUX REFINERY
PUBLIC HEARING AND REQUEST
FOR PUBLIC COMMENT ON 
PROPOSED PART 70 AIR
OPERATING PERMIT
MINOR MODIFICATION
The LDEQ, Office of Environmental Services, will conduct a public hearing to
receive comments on a proposed Part 70 air operating permit minor
modification for Murphy Oil USA, Inc., P. O. Box 100, Meraux, LA 70075 for
the Meraux Refinery. The facility is located at 2500 E. St. Bernard Highway,
Meraux, St. Bernard Parish.
The hearing will be held on Tuesday, July 7, 2008, beginning at 6:00 p.m.,
at the Nunez Community College Auditorium, 3710 Parish Road, Chalmette, LA.
During the hearing, all interested persons will have an opportunity to
comment on the proposed permit.
Murphy Oil USA, Inc. requested a minor permit modification to the existing
Permit No. 2500-00001-V4 dated January 15, 2009.
The facility proposes to construct and operate a BenFree Unit (BFU) in order
to comply with the US EPA Mobile Source Air Toxics (MSAT) Phase 2 final rule
requirements finalized on February 26, 2007. This rule will limit the
benzene content of the gasoline produced to an annual average of 0.62
percent by volume. This project will not result in any debottlenecking of
any other unit at the facility. Also, there will not be pure benzene streams
in the unit or in any storage tanks. The off gas from the BFU will be routed
to the existing fuel gas system for control and in an emergency to the
existing North Flare via the Area 6 flare knock out drum. The BFU will
comply with the New Source Performance Standard (NSPS), 40 CFR 60, Subpart
QQQ and National Emission Standards for Hazardous Air Pollutants (NESHAP),
40 CFR 61, Subpart FF. The BFU Reboiler will comply with NSPS, 40 CFR 60,
Subpart J. The facility will voluntarily equip the Reboiler with Ultra-low
NOx burn ers to reduce emissions. The associated fugitives from the BFU will
comply with NSPS, 40 CFR 60, Subpart GGGa. The BFU turnaround emissions
shall also be included in the overall facility turnaround emissions.
In addition Murphy Oil USA, Inc., is modifying the permit as shown below:

		1. Update the Crude, Middle Distillate, Heavy Oil, and Slop
Oil Tank CAPs which will result in a reduction of VOC emissions due to the
replacement, reconstruction, or reinstatement of tanks approved in previous
permits (2500-00001-V3 and V4);

2. Consolidation of Gasoline and Naphtha CAPs into one Gasoline/Naphtha CAP;
3. Update fugitive emissions associated with the tanks changes and the BFU
Project;
4. Update the facility turnaround emissions to include the BFU project and
the No. 2 Amine Unit;

		5. Cancellation of the rerouting of the Oily Water Stripper
vent stream to the fuel gas system. The Oily Water Stripper vent stream
shall continue to be routed to the North Flare, Emission Point 20-72;

6. Incorporate Boiler B-7 as a permanent equipment in order to meet the
steam demand at the facility;
7. Update the "Specific Requirements" and "Inventories" as appropriate; and

		8. Updated Refinery Turnaround Emissions, Emission Point
TRND, based on the planned turnarounds for the duration of this permit which
expires on November 20, 2012.
		
		This permit was processed as an expedited permit in
accordance with LAC 33:I.Chapter 18.

Estimated emission increases due to the BFU Project (Reboiler, Fugitives,
Cooling Tower, North Flare, Storage, BFU turnaround and startup/shutdown,
etc.) based on actual to potential in tons per year are shown in the
following table:

Estimated emissions increases due to the project are insignificant.
Therefore, PSD review (netting) is not required.

** Includes emissions increase from the BFU project and refinery turnaround
and startup/shutdown (5 years). The turnaround and startup/shutdown
emissions, in the past, used to be permitted under variances. Including
turnaround and startup/shutdown emissions in the permit will greatly assist
in air quality planning by clearly identifying, quantifying, and limiting
them where necessary. The turnaround and startup/shutdown emissions are not
subject to New Source Review as they are existing emissions and no new
modification is triggering an increase in the associated emissions. A
specific condition has been introduced in this permit to limit the
turnaround and startup/shutdown emissions, Emission Point TRND.
A technical review of the working draft of the proposed permit was submitted
to the facility representative and the LDEQ Surveillance Division. Any
remarks received during the technical review will be addressed in the
"Worksheet for Technical Review of Working Draft of Proposed Permit". All
remarks received by LDEQ are included in the record that is available for
public review.
