PUBLIC NOTICE LOUISIANA DEPARTMENT OF ENVIRONMENTAL QUALITY (LDEQ) MURPHY OIL USA, INC., 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 burners 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 (250000001-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:

Pollutant PM10 SO2 NOX CO VOC

Actual Baseline Emissions

2.04 26.85 9.75 23.25 36.89

Estimated emissions increases due to the project are insignificant. Therefore, PSD review (netting) is not required. Permitted emissions from the Meraux Refinery in tons per year are as follows: Pollutant PM10

** 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. Written comments or written requests for notification of the final permit decision regarding this permit may also be submitted to Ms. Soumaya Ghosn at LDEQ, Public Participation Group, P.O.
