Technical Support Document (TSD) for a Federally Enforceable Operating Permit (FESOP)

Source Background and Description

Source Name: Harrison Engine Service Source Location: 301 Detroit Street, LaPorte, Indiana 46350 County: LaPorte SIC Code: 7680 Operation Permit No.: F091-12536-00123 Permit Reviewer: ERG/MT The Office of Air Quality (OAQ) has reviewed a FESOP application from Harrison Engine Service relating to the operation of air craft cylinder rebuilding facility. Emission Units and Pollution Control Equipment The source consists of the following emission units and pollution control devices: (a) One (1) batch open top degreaser with a daily consumption rate of 1.996 gallons/day trichloroethylene used to degrease a maximum of 2.5 aluminum aircraft cyclinders/hour using superheated vapor, reduced room draft, and a freeboard ratio of 1.0 as volatile organic compound (VOC) controls and exhausting to stack, “Degreaser X;” (b) One (1) paint spray booth, identified as SGI, controlling particulate matter (PM) emissions with a dry paint filter and exhausting to stack “Paint X;” and (c) One (1) hard chromium electroplating operation with a maximum cumulative rectifier capacity of 97.02 million Ampere-hours (97,020,000 A-hr) consisting of: (1) Four (4) hard chromium electroplating tanks, identified as Tank 1, 2, 3, and 4, equipped with a composite mesh pad system exhausting to stack “Scrubber X.” Unpermitted Emission Units and Pollution Control Equipment There are no unpermitted facilities operating at this source during this review process. Insignificant Activities The source also consists of the following insignificant activities, as defined in 326 IAC 2-7-1(21): (a) Natural gas-fired combustion sources with heat input equal to or less than ten million (10,000,000) British thermal units per hour.Harrison Engine Service Page 2 of 9

LaPorte, Indiana 46350 T091-12536-00123 Permit Reviewer: ERG/MT

(1) One (1) natural gas boiler rated at 0.42 MMBtu/hour exhausting to stack “Boiler X”; (2) One (1) natural gas forced air furnace rated at 0.075 MMBtu/hour; (3) One (1) natural gas forced air furnace rated at 0.20 MMBtu/hour; (4) One (1) natural gas water heater rated at 0.04 MMBtu/hour exhausting to stack “Boiler X”; (5) One (1) natural gas cylinder expansion oven rated at 0.25 MMBtu/hour exhausting to stack “Expansion Oven;” and (b) The following equipment related to manufacturing activities not resulting in the emission of HAPs: brazing equipment, cutting torches, soldering equipment, welding equipment. (1) One (1) tungsten inert gas (TIG) welding operation consisting of two (2) welding stations identified as “TIG Weld 1" and TIG Weld 2" with a maximum metal consumption per station of 0.02 pounds/hours and exhausting to stack “Weld X.” Existing Approvals There are no existing approvals for this source.
Enforcement Issue (a) IDEM is aware that this facility is not in compliance with 326 IAC 2-8-2 which required the source to submit a Title V permit application by December 14, 1996, or have a FESOP issued by that date. (b) IDEM is reviewing this matter and will take appropriate action. This proposed permit is intended to satisfy the requirements of the operating permit rules.

Recommendation The staff recommends to the Commissioner that the FESOP be approved. This recommendation is based on the following facts and conditions: Unless otherwise stated, information used in this review was derived from the application and additional information submitted by the applicant. An administratively complete FESOP application for the purposes of this review was received on July 25, 2000. Emission Calculations (a) Chromium emissions (single HAP) from the biggest source in Indiana is less than ten (10) tons per year. Therefore, no calculations were necessary for the hard chromium electroplating operation because the emissions from this source will be ten (10) tons per year. (b) See Appendix A of this document for detailed emissions calculations pages 1-5.Harrison Engine Service Page 3 of 9

LaPorte, Indiana 46350 T091-12536-00123 Permit Reviewer: ERG/MT Potential To Emit Pursuant to 326 IAC 2-1.1-1(16), Potential to Emit is defined as “the maximum capacity of a stationary source to emit any air pollutant under its physical and operational design. Any physical or operational limitation on the capacity of a source to emit an air pollutant, including air pollution control equipment and restrictions on hours of operation or type or amount of material combusted, stored, or processed shall be treated as part of its design if the limitation is enforceable by the U. S. EPA.” This table reflects the PTE before controls. Control equipment is not considered federally enforceable until it has been required in a federally enforceable permit.

Pollutant Potential To Emit (tons/year) PM 0.1 PM-10 0.1 SO 2 0.0 VOC 13.5 CO 0.4 NO x 0.4 Note: For the purpose of determining Title V applicability for particulates, PM-10, not PM, is the regulated pollutant in consideration.

HAP’s Potential To Emit (tons/year) Trichloroethylene 13.4 Other Total HAPs <1.0 TOTAL 13.4

(a) The potential to emit(as defined in 326 IAC2-1.1-1(16) ) of any single HAP is equal to or greater than ten (10) tons per year. Therefore, the source is subject to the provisions of 326 IAC 2-7.
Actual Emissions No previous emission data has been received from the source.
Potential to Emit After Issuance The table below summarizes the potential to emit, reflecting all limits, of the significant emission units after controls. The control equipment is considered federally enforceable only after issuance of this Federally Enforceable State Operating Permit. The source is taking limits on HAP use in the degreasing operation to bring emissions of a single HAP to below ten.

The speed is equal to the distance in meters divided by the time in minutes. (ii) The monitoring shall be conducted monthly. If after the first year, no exceedances of the hoist speed are measured, the Permittee may begin monitoring the hoist speed quarterly. (iii) If the exceedance of the hoist speed occurs during quarterly monitoring, the monitoring frequency returns to the monthly until another year of compliance without an exceedance is demonstrated.Harrison Engine Service Page 6 of 9

LaPorte, Indiana 46350 T091-12536-00123 Permit Reviewer: ERG/MT (iv) If the Permittee can demonstrate to the commissioner’s satisfaction in the initial compliance report that the hoist cannot exceed a speed of 3.4 meters per minute (11 feet per minute), the required monitoring frequency is quarterly, including during the first year of compliance. (C) The Permittee shall conduct monitoring and record the results, for a reduced room draft, as specified in the following paragraphs: (i) The Permittee shall conduct an initial monitoring test and, thereafter, monthly monitoring tests of the windspeed within the enclosure, and a monthly visual inspection of the enclosure to determine if it is free of cracks, holes, and other defects. (3) Reporting Requirements: An annual report shall be submitted. This report shall include the requirements as follows: (a) A signed statement from the facility owner or his designee stating that , “All operators of solvent cleaning machines have received training on the proper operation of solvent cleaning machines and their control devices sufficient to pass the test required in 40 CFR 63.463(d)(10).” (b) An estimate of solvent consumption for each solvent cleaning machine during the reporting period. State Rule Applicability - Entire Source 326 IAC 2-6 (Emission Reporting) This source is located in LaPorte County and the potential to emit VOC, CO, SO 2 , and NOx is less than one hundred (100) tons per year. Its potential to emit PM10 is less than one-hundred (100) tons per year including fugitive emissions, therefore, 326 IAC 2-6 does not apply. 326 IAC 2-8 (FESOP) The potential to emit each individual HAP will be limited to less than 10 tons per year. This will limit emissions to less than major source levels rendering 326 IAC 2-7 (Part 70 Permit Program) not applicable. 326 IAC 5-1 (Visible Opacity Limitations) Pursuant to 326 IAC 5-1-2 (Opacity Limitations), except as provided in 326 IAC 5-1-3 (Temporary Alternative Opacity Limitations), opacity shall meet the following, unless otherwise stated in this permit: (a) Opacity shall not exceed an average of forty percent (40%) any one (1) six (6) minute averaging period as determined in 326 IAC 5-1-4. (b) Opacity shall not exceed sixty percent (60%) for more than a cumulative total of fifteen (15) minutes (sixty (60) readings as measured according to 40 CFR 60, Appendix A, Method 9 or fifteen (15) one (1) minute nonoverlapping integrated averages for a continuous opacity monitor) in a six (6) hour period.Harrison Engine Service Page 7 of 9

LaPorte, Indiana 46350 T091-12536-00123 Permit Reviewer: ERG/MT State Rule Applicability - Individual Facilities 326 IAC 6-2-4 (a) Particulate emissions from indirect heating facilities constructed after September 21, 1983 shall be limited by the following equation:
Pt = 1.09

Q 0.26

Where: Pt = Pounds of particulate matter emitted per million Btu (lb/MMBtu) heat input. Q = Total source maximum operating capacity rating in million Btu per hour (MMBTU/hr) heat input. The maximum operating capacity rating is defined as maximum capacity at which the facility is operated or the nameplate capacity, whichever is specified in the facility's permit application, except when some lower capacity is conducted in the facility's operation permit; in which case, the capacity specified in the operation permit shall be used. For the boiler used at Harrison Engine, the Pt would be calculated to be 1.4 pound per MMBtu. For Q less than 10 MMBtu/hr, Pt shall not exceed 0.6 pounds per MMBtu therefore the limit for the boiler will be set at 0.6 pounds per MMBtu. (b) Based on the emission calculations this boiler emits less than 0.6 pounds per MMBtus. 326 IAC 6-3-2 (Process Operations) The particulate matter (PM) from the paint booth SG1, and the insignificant welding operation shall be limited by the following. For the welding operation, the allowable PM emission rate shall not exceed 0.551 pounds per hour when operating at a process weight rate of less than 100 pound per hour. Interpolation of the data for the process weight rate up to sixty thousand (60,000) pounds per hour shall be accomplished by use of the equation: E = 4.10 P 0.67 where E = rate of emission in pounds per hour and P = process weight rate in tons per hour The dry paint filter shall be in operation at all times the paint booth is in operation, in order to comply with this limit. 326 IAC 8-1-6 (New Facilities) The open top vapor degreaser is not subject to 326 IAC 8-1-6 because it was installed in 1963 and is therefore not a new facility and the VOC emissions are less than twenty-five (25) tons per year. The spray paint booth is not subject to 326 IAC 8-1-6 because the potential VOC emissions are less than twenty-five (25) tons per year. 326 IAC 8-2-9 (Miscellaneous Metal Coatings) The spray paint booth is not subject to 326 IAC 8-2-9 because the source is located in LaPorte County, the potential VOC emissions are less than twenty-five (25) tons per year, and the actual VOC emissions are less than fifteen (15) pound per day. 326 IAC 8-3 (Organic Solvent Degreaser Operations) The open top vapor degreaser is not subject to 326 IAC 8-3 because it was installed in 1963 and the source is in LaPorte County.Harrison Engine Service Page 8 of 9

LaPorte, Indiana 46350 T091-12536-00123 Permit Reviewer: ERG/MT 326 IAC 8-6-1 (Organic Solvent Emission Limitation) The open top vapor degreaser and spray paint booth are not subject to 326 IAC 8-6-1 because the potential VOC emissions from these facilities is less than one-hundred (100) tons per year. Compliance Requirements Permits issued under 326 IAC 2-8 are required to ensure that sources can demonstrate compliance with applicable state and federal rules on a more or less continuous basis. All state and federal rules contain compliance provisions, however, these provisions do not always fulfill the requirement for a more or less continuous demonstration. When this occurs IDEM, OAQ, in conjunction with the source, must develop specific conditions to satisfy 326 IAC 2-8-4. As a result, compliance requirements are divided into two sections: Compliance Determination Requirements and Compliance Monitoring Requirements. Compliance Determination Requirements in Section D of the permit are those conditions that are found more or less directly within state and federal rules and the violation of which serves as grounds for enforcement action. If these conditions are not sufficient to demonstrate continuous compliance, they will be supplemented with Compliance Monitoring Requirements, also Section D of the permit. Unlike Compliance Determination Requirements, failure to meet Compliance Monitoring conditions would serve as a trigger for corrective actions and not grounds for enforcement action. However, a violation in relation to a compliance monitoring condition will arise through a source’s failure to take the appropriate corrective actions within a specific time period. The compliance monitoring requirements applicable to this source are as follows:
1. The batch open top degreaser has applicable compliance monitoring conditions specified below: (a) The Permittee shall record the temperature at the center of the superheated solvent vapor zone while the solvent cleaning machine is in the idling mode. The temperature shall be at least 10 E F above the solvents boiling point. (b) The Permittee shall determine the hoist speed monthly in the first year and quarterly thereafter unless an exceedance occurs. The hoist speed must be 3.4 meters per minute or less. (c) The Permittee shall conduct monthly monitoring of the windspeed of the enclosure and a monthly visual inspection of the enclosure to determine if it is free of cracks, holes, and other defects. Windspeed shall not exceed 15.2 meters per minute. (d) The Permittee shall maintain records of the HAP usage for each single HAP for each month and the weight of each single HAP emitted. The source shall use less than ten (10) tons per year of a single HAP. These monitoring conditions are necessary to ensure compliance with 326 IAC 2-8 (FESOP) and 326 IAC 20 (40 CFR Part 63 Subpart T)
2. The chrome electroplating operation has applicable compliance monitoring conditions specified below. (a) Tanks 1, 2, 3, and 4 shall be operated such that the pressure drop across the composite mesh-pad system shall be operated within ±1 inch of water column of the pressure drop value established during the initial performance test, or within the range of compliant values for pressure drop established during multipleHarrison Engine Service Page 9 of 9

LaPorte, Indiana 46350 T091-12536-00123 Permit Reviewer: ERG/MT performance tests. The pressure drop shall be monitored once each day that a hard chromium electroplating tank is operating. These monitoring conditions are necessary to ensure compliance with 326 IAC 2-8 (FESOP) and 326 IAC 20 (40 CFR Part 63, Subpart N) Conclusion The operation of this aircraft cylinder rebuilding facility shall be subject to the conditions of the attached proposed (FESOP No.: F091-12536-00123).Page 1 of 3

Trials reported for wet cutting of 8 mm thick mild steel with 3.5 m/min cutting speed (at 0.2 g/min emitted). Therefore, the emission factor for plasma cutting is for 8 mm thick rather than 1 inch, and the maximum metal thickness is not used in calculating the emissions. Using AWS average values: (0.25 g/min)/(3.6 m/min) x (0.0022 lb/g)/(39.37 in./m) x (1,000 in.) = 0.0039 lb/1,000 in. cut, 8 mm thick Cutting emissions, lb/hr: (# of stations)(max. metal thickness, in.)(max. cutting rate, in./min.)(60 min./hr.)(emission factor, lb. pollutant/1,000 in. cut, 1" thick) Welding emissions, lb/hr: (# of stations)(max. lbs of electrode used/hr/station)(emission factor, lb. pollutant/lb. of electrode used) Emissions, lbs/day = emissions, lbs/hr x 24 hrs/day Emissions, tons/yr = emissions, lb/hr x 8,760 hrs/year x 1 ton/2,000 lbs.
