Entergy Mississippi LLC, Gerald Andrus Plant (“Gerald Andrus”), located at 200 M P and L Road, Highway 82 West, in Greenville, MS, (601) 379-2916, has applied to the Mississippi Department of Environmental Quality (MDEQ) for the following permitting action(s):  Reissuance of Title V Operating Permit (TVOP) Ref. No. 2800-00048. The applicant's operations fall within SIC Code 4911.  A Statement of Basis has been prepared that contains a discussion of the decision-making that went into the development of the permit and provides the permitting authority, the public, and other government bodies a record of the technical issues surrounding issuance of the permit. The Statement of Basis also addresses any changes to emissions and/or discharges resulting from any modification of the facility.  
Gerald Andrus is an existing electrical power generation plant that utilizes steam generating boilers. The facility has the potential to operate four boilers. The 7,275 MMBtu/hr Steam Generating Boiler (Emission Point AA-001) is the main energy generating unit. The facility can use two 230 MMBtu/hr Auxiliary Boilers (Emission Points AB-001 and AC-001) to improve the startup process. The facility can potentially utilize a 90 MMBtu/hr Temporary/Auxiliary Boiler (Emission Point AA-005) for startup; however, Emission Point AA-005 is only brought on-site for temporary occasions. Emission Points AA-001, AB-001, and AC-001 are able to fire natural gas and No. 2 fuel oil. Emission Point AA-005 is able to fire natural gas and No. 2 fuel oil. The facility keeps two Emergency Generators (Emission Points AA-002 and AA-004) onsite for backup power and an Emergency Fire Water Pump (Emission Point AA-006) for emergency situations. Emission Points AA-002 and AA-004 are 800 hp (5.6 MMBtu/hr) and 150 hp (1.05 MMBtu/hr), respectively, and fire ultra-low-sulfur-diesel (ULSD). The emission sources emit the following pollutants: Particulate Matter (PM), PM less than 10 micrometers in diameter (PM10), PM less than 2.5 micrometers in diameter (PM2.5), Sulfur Dioxide (SO2), Nitrogen Oxide (NOx), Carbon Monoxide (CO), Volatile Organic Compounds (VOC), and Hazardous Air Pollutant (HAP).
The facility operates fossil-fuel boilers totaling more than 250 MMBtu/hr heat input. Therefore the facility is one of the 28 categorical facilities listed in 40 CFR 52.21(b)(1)(i)(a) which sets the PSD threshold for a major source as 100 tpy.  The facility has the potential-to-emit (PTE) more than 100 tons per year (tpy) of the following PSD regulated pollutants: PM, NOx, SO2, and CO. The facility is a PSD major stationary source. Additionally, the facility’s PTE exceeds the Title V major source threshold of 100 tpy for each of the following criteria air pollutants: PM10, PM2.5 SO2, CO, and VOC. The facility’s HAP PTE exceeds the major source threshold of 25 tpy of total HAPs and 10 tpy for any individual HAP. Gerald Andrus is a Title V major source.
The permitting action will make the following changes to the Title V Operating Permit: update the Cross State Air Pollution Rule applicability, clarify State PM standards, removed hourly limitations on Emission Point AA-005 that were more stringent than applicable Federal standards.
The staff of the Permit Board has developed this draft permit based on information submitted to the Permit Board by the applicant, appropriate State and Federal agencies and other interested parties. The staff of the Permit Board is soliciting all relative information pertaining to the proposed activity, including public comment, to ensure that the final staff recommendation on the draft permit complies with all State and Federal regulations. Public review and comment on the draft permit and supporting documentation is an important element in the staff evaluation and resulting recommendation to the Permit Board. The draft permit conditions have been developed to ensure compliance with all State and Federal regulations but are subject to change based on information received as a result of public participation.
Persons wishing to comment upon or object to the proposed determinations are invited to submit comments in writing to Slater Smith at https://www.mdeq.ms.gov/smith-slater/ or to the Permit Board address shown above, no later than the end of the thirty (30) day public notice. All comments received by this date will be considered in the formulation of final determinations regarding the application(s). A public hearing will be held if the Permit Board finds a significant degree of public interest in the proposed permit(s). Persons wishing to request a public hearing may do so by submitting that request in writing to Slater Smith at https://www.mdeq.ms.gov/smith-slater/ or to the Permit Board address shown above. The Permit Board is limited in the scope of its analysis to environmental impact. Any comments relative to zoning or economic and social impacts are within the jurisdiction of local zoning and planning authorities and should be addressed to them.
After receipt of public comments and thorough consideration of all comments, the staff will formulate its recommendations for permit issuance and a proposed permit if that is the recommendation. The Title V Permit to Operate is a permit that is required by Title V of the Federal Clean Air Act and the Mississippi Air and Water Pollution Control Law. The Title V permit is a Federally-enforceable permit as well as a State permit.  Therefore, the U.S. Environmental Protection Agency (EPA) will also be allowed an opportunity to review the application, proposed permit, and all comments received during the public comment period prior to Permit Board action on the application.
