FACILITY DESCRIPTION

Resinall Corp (Resinall) is an existing specialty resin manufacturing facility (SIC Code 2821). The facility operates under Synthetic Minor Operating Permit (SMOP), Air Ref. No.: 0800-00009.

Resinall operates reactor and storage tanks, railcar and truck loading stations, three emergency generators, an emergency fire water pump, and three steam generating boilers. The boilers are capable of combusting natural gas, distillate fuel oil, and a specialty fuel, Zecosol. The facility has the potential to emit Particulate Matter (PM), PM less than 10 μm in diameter (PM10), PM less than 2.5 μm in diameter (PM2.5), Sulfur Dioxide (SO2), Carbon Monoxide (CO), Volatile Organic Compounds (VOC), and Hazardous Air Pollutant (HAP) emissions. The facility has the potential to exceed the Title V major source threshold for SO2. Resinall remains under the Title V threshold by limiting facility-wide SO2 emissions to 99.0 tons per year (tpy) and total distillate fuel oil and Zecosol combustion to 2,800,000 gallons per year. 

PROJECT/PERMIT ACTION DESCRIPTION

The facility submitted an application for a modification to the SMOP issued on May 24, 2022. The following changes have been included in the draft permit: 

•	Removed and replaced a 1,000 kW (1,341 hp) Compression Ignition (CI) Emergency Generator (Emission Point AA-015) with a 1,140 kW (1,528 hp) CI Emergency Generator (Emission Point AA-016)

o	Emission Point AA-016 has a displacement per cylinder > 30 liters, changing the applicable regulations from 40 CFR 63, Subpart ZZZZ to 40 CFR 60, Subpart IIII.

•	Administrative change to the description of Emission Point AK-005 from a 4,000-gallon Resin Batch Reactor Kettle to a 4,000-gallon Resin Batch or Continuous Reactor Kettle

o	This change in method of operation will not result in changes to the potential to emit or regulator applicability for Emission Point AK-005.

•	Update the incorrectly described ULSD Emergency Generator (Emission Point AA-020) from 186 kW (250 hp) to 250 kW (335 hp)

EMISSION SUMMARY

Total HAP	8.38	8.38	No5	
Notes:
1.	Uncontrolled emissions without control devices or limitations.
2.	Facility proposed emission limitation.
3.	Facility proposed allowable emissions are reduced by fuel combustion limitation.
4.	The Title V major source threshold for criteria pollutants (PM10, SO2, NOx, CO, and VOC) is 100 tpy.
5.	The Title V major source threshold for individual and total HAP emissions are 10 and 25 tpy, respectfully.	

Table 2 demonstrates that Resinall has the potential to exceed the Title V major source threshold of 100 tpy for SO2 emissions. The facility will limit facility-wide SO2 emissions to 99.0 tpy and distillate fuel oil and Zecosol fuel combustion to 2,800,000 gallons per year. Monitoring, recordkeeping, and submittal requirements will be used to demonstrate compliance with the proposed limitations. 

APPLICABLE/PROPOSED PERMIT LIMITATIONS

The following conditions are included in the permit to ensure that Resinall remains below the Title V major source thresholds:

•	Limit SO2 emissions to 99.0 tpy, as determined on a monthly basis and for each consecutive 12-month period on a rolling basis.

o	Demonstrate compliance by monitoring and keeping records of SO2 emissions on a monthly basis and for each consecutive 12-month period on a rolling basis. SO2 emissions shall be determined by, but no limited to, engineering calculations, fuel combustion, hours of operation, and manufacturer’s specifications.

o	Perform a semiannual test, not to exceed seven months, on Zecosol to determine the sulfur content of the fuel. The fuel test shall be conducted using an EPA approved test method.

•	For the entire facility, the permittee shall limit the total combustion of distillate fuel oil and Zecosol to 2,800,000 gallons per year, as determined on a monthly basis and for each consecutive 12-month period on a rolling basis.

o	Monitor and record the total combustion of distillate fuel oil and Zecosol, as determined on a monthly basis and for each consecutive 12-month period on a rolling basis. Fuel combustion shall be calculated using, but not limited to, purchase orders, delivery receipts, manufacturer’s specifications, and hours of operation.

NSPS APPLICABILITY

40 CFR 60, Subpart Dc (Standards of Performance for Industrial-Commercial-Institutional Steam Generating Units): Subpart Dc was promulgated to regulate SO2 and PM emissions generated by steam generating units. Units subject to Subpart Dc commenced construction, modification, or reconstruction after June 9, 1989, and that has a maximum heat input capacity from fuels combusted in the steam generating unit of 100 MMBtu/hr or less, but greater than 10 MMBtu/hr. Emission Points AA-001 and AA-002 were constructed before 1984 and are not subject to 40 CFR 60, Subpart Dc. Emission Point AA-018 is subject to Subpart Dc because the boiler was constructed after 1989 and has a heat input capacity greater than 10 MMBtu/hr (21 MMBtu/hr). Emission Point AA-018 is subject to the fuel sulfur standard and will demonstrate compliance by fuel supplier certification.

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): Subpart Kb establishes emission limitations and operating limitations for each storage vessel with a capacity greater than or equal to 19,812.9 gallons that is used to store volatile organic liquids for which construction, reconstruction, or modification is commenced after July 23, 1984. Subpart Kb does not apply to storage vessels with a capacity greater than or equal to 39,890 gallons storing a liquid with a maximum true vapor pressure less than 3.5 kilopascals (kPa) or with a capacity greater than or equal to 19,812.9 gallons but less than 39,890 gallons storing a liquid with a maximum true vapor pressure less than 15.0 kPa. While the facility’s storage tanks are described to contain various materials, all emissions produced by the tanks were calculated using the worst-case materials (M47 oil or Zecosol) as the most conservative calculations. The applicability for the facility’s storage vessels can be summarized by the following bullet points. Each storage tank is listed in Table 2 where the individual applicability is explained. As shown in the table below, there are no storage tanks which meet the applicability of Subpart Kb; thus, Resinall is not subject to 40 CFR 60, Subpart Kb.

•	Emission Points are not subject to Subpart Kb if the storage vessels do not meet the design capacity (< 19,813 gallons) requirement.

•	Emission Points are not subject to Subpart Kb if the design capacities of the tanks are between 19,813 and 39,890 gallons but maximum true vapor pressures are less than 15 kPa (2.17 psia).

40 CFR 60, Subpart IIII (Standards of Performance for Stationary Compression Ignition Internal Combustion Engine): Subpart IIII establishes emission limitations and management practices for stationary CI reciprocating internal combustion engines (RICE). Emission Point AA-016 is a 1,140 kW (1,528 hp) CI 4-Stroke Emergency Generator RICE with a model year after April 1, 2006 (2020). Emission Point AA-016 is subject to Subpart IIII. Emission Point AA-020 is a CI RICE that is potentially subject to Subpart IIII; however, the model year of the RICE is before April 1, 2006 (2004). Emission Point AA-026 is a 186 kW (250 hp) Ultra-Low Sulfur Diesel-fired (ULSD) CI 4-Stroke Emergency Fire Water Pump RICE with a model year after April 1, 2006 (2012). Emission Point AA-026 is subject to Subpart IIII. Emission Point AA-026 will also comply with the applicable standards of the Diesel Fuel and ECA Marine Fuel Standards (40 CFR 1090.300(a) and 1090.305, Subpart D) which requires the Emergency Fire Water Pump RICE to only combust ULSD.

40 CFR 60, Subpart JJJJ (Standards of Performance for Stationary Spark Ignition Internal Combustion Engines): Subpart JJJJ establishes emission limitations and management practices for stationary SI reciprocating internal combustion engines (RICE). Emission Point AA-027 is a 40 kW (54 hp) Natural gas-fired SI 4-Stroke Lean Burn Emergency Generator RICE with a model year after January 1, 2009 (2012). Emission Point AA-027 is subject to Subpart JJJJ. Emission Point AA-027 will comply with the emission standards of 40 CFR 60.4233(d), Table 1 to Subpart JJJJ (Footnote c), Subpart JJJJ and the emergency engine hours of operation standards.

MACT APPLICABILITY

40 CFR 63, Subpart ZZZZ (National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines): Subpart ZZZZ establishes national emission limitations and operating limitations for HAP emissions from stationary reciprocating internal combustion engines (RICE) located at major and area sources of HAP emissions. Subpart ZZZZ also establishes requirements to demonstrate initial and continuous compliance with the emission limitations and operating limitations. Resinall is an area source for HAP emissions, as seen in Table 1, and operates four RICE; therefore, the facility is potentially subject to Subpart ZZZZ. Emission Point AA-020 is a 250 kW (335 hp) Ultra-Low Sulfur Diesel-fired (ULSD) CI 4-Stroke Emergency Generator RICE with a model year of 2004. Emission Point AA-020 is subject to Subpart ZZZZ and will comply with the work practice standards, emergency engine requirements, and applicable monitoring, recordkeeping and submittal requirements. Emission Points AA-016, AA-026, and AA-027 are considered new stationary RICE under 40 CFR 63.6590(a)(2)(iii), Subpart ZZZZ. Emission Points AA-016 and AA-026 are subject to regulations under 40 CFR 60, Subpart IIII, and Emission Point AA-027 is subject to regulations under 40 CFR 60, Subpart JJJJ, as described above. According to 40 CFR 63.6590(c)(1), Subpart ZZZZ, the permittee shall meet the requirements of Subpart ZZZZ by meeting the requirements of 40 CFR 60, Subpart IIII and 40 CFR 60, Subpart JJJJ.

40 CFR 63, Subpart DDDDD (National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters): Facilities subject to Subpart DDDDD own or operate an industrial, commercial, or institutional boiler or process heater as defined in 40 CFR 63.7575, Subpart DDDDD that is located at, or is part of, a major source of HAP, except as specified in 40 CFR 63.7491, Subpart DDDDD. For purposes of Subpart DDDDD, a major source of HAP is as defined in 40 CFR 63.2, Subpart A, except that for oil and natural gas production facilities, a major source of HAP is defined in 40 CFR 63.7575, Subpart DDDDD. Subpart DDDDD establishes national emission limitations and work practice standards for HAP emissions from industrial, commercial, and institutional boilers and process heaters located at major sources of HAP.
