Company Name:	Farmers Grain Terminal Inc., Greenville

Facility Location:	Harbor Front Industrial Park, Greenville, MS

Source Number:	2800-00066

County: 		Washington

FACILITY DESCRIPTION
Farmer’s Grain Terminal, Inc. (FGT) operates an existing grain elevator located in Greenville, Mississippi. The facility accepts grains such as corn, soybeans, wheat, milo, and occasionally rice and stores them in storage bins. Total storage capacity of the forty-nine (49) bins located at FGT is approximately 13,401,910 bushels. Grains are received from hopper trucks, and the grains are shipped/loaded into trucks or barges. The facility operates under the Standard Industrial Classification (SIC) Code 5153, Grain and Field Beans and North American Industry Classification System (NAICS) Code 424510, Grain and Field Bean Merchant Wholesalers.

Once grain has been delivered, it is transferred into bins for storage via elevator legs until such time it is loaded into a truck or onto a barge for delivery. When necessary, grains may be dried in one of two natural gas-fired column dryers. The dryers are the only fuel burning sources at the site. FGT operates two (2) baghouses which are used to control particulate matter (PM) emissions from various processes at the facility. A description of the air emissions equipment is contained in the following table.

PROJECT/PERMIT ACTION DESCRIPTION
The purpose of this permit action is to renew the facility’s Synthetic Minor Operating Permit (SMOP) which expired December 31, 2024. The only notable change to the proposed permit is the removal of Emission Point CD-003 from the permit. FGT submitted a request to modify the SMOP in September 2022 to remove Emission Point CD-003 from operation. This baghouse was previously used to control emissions from the No. 1 barge loadout activities; however, FGT added additional enclosures to the barge loadout conveyors and no longer needed the baghouse. Other minor changes to the language in the previous permit are also included in the proposed permit. 

EMISSION SUMMARY
The following table contains a summary of the facility’s uncontrolled and allowable emissions.

Pollutant	Uncontrolled Emissions
(TPY)	Allowable Emissions 
(TPY)	
PM	303.67	249.0	
PM10	105.52	99.0	
PM2.5	20.48	99.0	
SO2	0.25	0.11	
NOx	41.53	17.59	
CO	34.88	14.77	
VOC	2.29	0.97	
TRS	0.00	0.00	
Lead	0.00	0.00	
Total HAP	0.78	0.33	
 NOTE: The amount of grain dried each year is limited; therefore, the amount of time the two (2) driers are operational is also limited. As such, the allowable emissions of SO2, NOx, CO, and VOC are less than the potential uncontrolled emissions.

NSPS APPLICABILITY
40 CFR 60, Subpart Kb, Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced after July 23, 1984 – The provisions of Subpart Kb are applicable to storage vessels with a capacity greater than or equal to 75 cubic meters (m3) (19,813 gallons), is used to store volatile organic liquids, and is constructed, reconstructed, or modified after the applicability date. The 2,000-gallon diesel storage vessel at the facility was constructed after the applicability date but it does not have a capacity that exceeds the applicability threshold. Therefore, it is not subject to the Subpart Kb requirements. 

40 CFR 60, Subpart DD, Standards of Performance for Grain Elevators – The provisions of Subpart DD are applicable to grain terminal or storage elevators which commence construction, modification, or reconstruction after August 3, 1978. The facility was constructed after the applicability date; therefore, the facility is subject to the requirements of Subpart DD. The affected facilities at the site include the truck loading and unloading stations, the barge and ship loading and unloading stations, the railcar loading and unloading stations, the grain dryers, and all grain handling operations. The facility’s loading/unloading operations and the grain handling operations are applicable to the Subpart DD opacity standards. The column grain dryers have screen perforations of less than 2.4 mm (0.094 inches); therefore, they are exempted from the Subpart DD opacity limit. The two (2) baghouses have applicable emission and opacity limits. All applicable requirements of Subpart DD are contained in the proposed permit.

40 CFR 60, Subpart Dc, Standards of Performance for Small Industrial-Commercial-Institutional Steam Generating Units – The provisions of Subpart Dc are applicable to steam generating units for which construction, modification, or reconstruction commenced after June 9, 1989, and the steam generating unit has a maximum design heat input capacity of 100 MMBtu/hr or less, but greater than or equal to 10 MMBtu/hr. The facility has two (2) natural gas-fired column grain dryers that were constructed after the applicability date, and they both have a maximum design heat input that are within the applicability threshold range. However, neither are considered steam generating units; therefore, they are not subject to the requirements of Subpart Dc.

MACT APPLICABILITY
The facility is considered an area source of HAP emissions, and no process equipment is subject to one of the area source NESHAP standards.
