FACILITY DESCRIPTION

Producer’s Rice Mill Inc (Producers) is a rice mill categorized under SIC 2044 (Rice Milling). The facility’s primary function is the intake of rice, which is then processed and milled, before being stored and prepared for shipping to distributors. 

Rice is received at the facility via Headhouse #5 (Emission Point AA-001), except during situations of quality control/emergency, in which case intake is handled via Headhouse #1 (AA-025) or via barge (AA-030). Once received, the rice is then either conveyed into the mill for additional processing or is loaded to a barge (AA-022) for shipping. The following table includes the emission points at the facility.

PROJECT/PERMIT ACTION DESCRIPTION

Producers applied for a reissuance of their synthetic minor operating permit (SMOP) with modifications in 2022. The modifications requested in the initial reissuance application are as follows:

1)	Emission Point AA-027 is requested to be removed.
The mill destoners SN-37 (Emission Point AA-027) have been decommissioned and the emission point is being removed from the permit. The baghouse that previously controlled this emission point has been repurposed to control Emission Point AC-001.

2)	Emission Point AA-004 is requested to be removed.
Rice mill final sorting SN-09 (Emission Point AA-004) has been relocated and integrated into the main rice mill.

3)	Emission Point AC-001 is being modified.
The hull tanks SN-27 (Emission Point AC-001) was previously controlled by a bin vent. The baghouse that previously controlled Emission Point AA-027 has been repurposed to control this emission point.

4)	Emission Point AA-015 is being modified.
SN-21 (Emission Point AA-015) was previously described as “White Rice MTMA with Baghouse”. This description is being updated to “Parboil Dust Cleaning with Baghouse”. This more accurately reflects the use of this process at the facility.

In 2025, Producers submitted an addendum to the initial application. In it, the facility outlined modifications that had been made to the facility since the initial application was submitted. However, these modifications were not previously requested or submitted to the DEQ for review or approval before being implemented. The facility states that “changes [made] to the facility do not constitute modifications and meet the definition of an administrative permit amendment under 11 Miss. Admin. Code Pt. 2, R. 6.4.D”. Chapter 6 of Part 2 of the Mississippi State Air Regulations only applies to Title V sources. This facility operates as a Synthetic Minor Source, and as such, does not meet the definition of a Title V source, and is not applicable to Title V regulations, or exceptions.

 The changes are as follows:

1)	The following Emission Points have been decommissioned at the site
a.	Emission Point AA-002 – SN-06 Headhouse #4 (Nuisance Dust) with Baghouse
b.	Emission Point AA-003 – SN-07 Headhouse #4 (6 Storage Bins) with Bin Vents
c.	Emission Point AA-024 – SN-08 Headhouse #4 Loadouts 

2)	The following, unpermitted Emission Points have been added to the site
a.	Proposed Emission Point AA-033c – SN-41c By-Products Storage Bins Parboil Bran Receiving
b.	Proposed Emission Point AA-036 – SN-44 Headhouse #5 Nuisance Dust Receiver Baghouse
c.	Proposed Emission Point AA-037 – SN-45 Rice Mill Parboil Dehulling

3)	The following Emission Points have had their operations modified due to the above changes.
a.	Emission Point AA-007 – SN-13 name changed from “Parboil Dust Cleaning with Baghouse” to “Rice Mill White Rice Dust Control Baghouse”
b.	Emission Point AA-008 – SN-14 name changed from “Rice Bran Removal and Collection with Baghouse” to “Rice Mill Bran from #3 Break Baghouse”
c.	Emission Point AA-020 – SN-26 name change from “White Rice Dust Control with Baghouse” to “Parboil Bran from #1 Break with Baghouse”. This name change was not associated with the addendum application, but was brought to MDEQ’s attention during a compliance inspection.
d.	Emission Point AA-031 – SN-40 name changed from “By-Products Loadout with Baghouse” to “Co-Products Loadout”
e.	Emission Points AA-032a and AA-032b – SN-41a and SN-41b have had the Proposed Emission Point AA-033c added to their bubble grouping.
f.	Emission Point AA-034 – SN-43 name changed from “Calcium Carbonate and Bin Vent” to “Calcium Bin and Bin Vent”

EMISSION SUMMARY

Criteria Pollutant	Maximum  Uncontrolled1	Title V Threshold	Exceed Title V Threshold?	Potential Controlled	
Carbon Monoxide (CO)	35.97	100	No	35.97	
Nitrogen Oxides (NOx)	42.82	100	No	42.82	
Sulfur Dioxide (SO2)	0.26	100	No	0.26	
Particulate Matter 10 (PM10)	320.43	100	Yes	63.49	
Volatile Organic Compounds (VOC)	2.36	100	No	2.36

Individual HAP (Hexane)   	0.77	10	No	0.77	
1.	All emissions are expressed in units of tons per year (tpy).

As shown in the table above, Producers has the ability to exceed the Title V threshold for PM10. In order to qualify as a synthetic minor source, the facility has previously taken federally enforceable limitations that require the facility not exceed a 12-month throughput of 1.1 million tpy of total rice production. The facility shall also maintain the baghouses on site at all times and shall perform mass balance calculations ensuring that PM10 emissions remain below 99.0 tpy.

The facility does not request any new limitations with the issuance of this permit and will maintain these previous limitations.

New Source Performance Standards (NSPS) Applicability

40 CFR Part 60, Subpart DD – Standards of Performance for Grain Elevators and Processing Facilities
This subpart applies affected facilities at any grain terminal elevator or any grain storage elevator and establishes emissions guidelines for Particulate Matter (PM). While Producers does meet the definition of a grain storage elevator, the facility was constructed prior to August 3, 1978 and as such, is not subject to this subpart.

National Emission Standards for Hazardous Air Pollutants (NESHAPs) Applicability

40 CFR Part 63, Subpart JJJJJJ – National Emission Standards for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers Area Sources
This subpart applies to owners and operators of industrial, commercial, or institutional boilers that are located at an area source of HAPs. Emission Point AB-001, a 29.5 MMBtu/hr boiler, is potentially subject to this subpart. However, Emission Point AB-001 uses natural gas as its only combustible fuel source and therefore meets the definition of a “gas-fired” boiler. Under 40 CFR 63.11195(e), this emission point is not subject to this subpart. 

PUBLIC PARTICIPATION

The 30-day public notice period began on July 1, 2026, when the notice was posted on MDEQ’s website and ends July 31, 2026.
