Technical Support Document (TSD) for a Minor Source Operating Permit

Source Background and Description
Source Name: Biddle Precision Components, Inc. Source Location: 701 South Main Street, Sheridan, IN 46049 County: Hamilton SIC Code: 3451 MSOP No.: 057-11705-00048 Permit Reviewer: Phillip Ritz/EVP The Office of Air Management (OAM) has reviewed an application from Biddle Precision Components, Inc. relating to the operation of a hard chromium electroplating operation coating steel. Permitted Emission Units and Pollution Control Equipment The source consists of the following permitted emission units and pollution control devices: (a) Six (6) hard chromium electroplating operations, identified as CH 1, CH 2, CH 3, CH 5 and CH 6, using a composite mesh-pad system for control, each having a rectifier with a maximum potential capacity of 5,000 amperes and exhausting to one (1) stack identified as S1; and (b) One (1) hard chromium electroplating operation, identified as CH 4, using a composite mesh-pad system for control, having a rectifier with a maximum potential capacity of 4,000 amperes and exhausting to one (1) stack identified as S1.

Sheridan, Indiana MSOP057-11705-00048 Permit Reviewer: PR/EVP Page 2 of 5

Recommendation The staff recommends to the Commissioner that the operation 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. A complete application for the purposes of this review was received on December 27, 1999. Emission Calculations Chromium emissions (Single HAP) from the biggest source in Indiana is less than (10) tons per year and Biddle Precision Components, Inc. is a much smaller source in comparison. So no calculations were necessary for this source because the emissions from this source will be less than ten (10) tons per year.
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 or emissions unit 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, the department, or the appropriate local air pollution control agency.”

Pollutant Potential To Emit (tons/year) PM 0.00 PM-10 0.00 SO 2 0.00 VOC 0.00 CO 0.00 NO x 0.00

HAP’s Potential To Emit (tons/year) Nickel Compounds Less Than 10 Chromium Compounds Less Than 10 TOTAL Less Than 25 (a) The potential to emit (as defined in 326 IAC 2-7-1(29)) of any single HAP is less than ten (10) tons per year and the potential to emit (as defined in 326 IAC 2-7-1(29)) of a combination HAPs is less than twenty-five (25) tons per year. Therefore, the source is not subject to the provisions of 326 IAC 2-7. (b) This new source is subject to 326 IAC 20-8 but not subject to 326 IAC 2-5.5-1 (b)(2) (registration) because the source consists of only hard chromium (not decorative chromium) electroplating tanks and the source emits less than major source levels (see statement (a) above). Therefore, the source is subject to the provisions of 326 IAC 2- 6.1-3(a).
Actual Emissions No previous emission data has been received from the source.Biddle Precision Components, Inc.

Sheridan, Indiana MSOP057-11705-00048 Permit Reviewer: PR/EVP Page 3 of 5

County Attainment Status The source is located in Hamilton County.

Pollutant Status PM-10 attainment SO 2 attainment NO 2 attainment Ozone attainment CO attainment Lead attainment (a) Volatile organic compounds (VOC) and oxides of nitrogen (NOx) are precursors for the formation of ozone. Therefore, VOC emissions are considered when evaluating the rule applicability relating to the ozone standards. Hamilton County has been designated as attainment or unclassifiable for ozone. Therefore, VOC and NOx emissions were reviewed pursuant to the requirements for Prevention of Significant Deterioration (PSD), 326 IAC 2-2 and 40 CFR 52.21.
Source Status Existing Source PSD, Part 70 or FESOP Definition (emissions after controls, based on 8,760 hours of operation per year at rated capacity and/ or as otherwise limited):
Pollutant Emissions (ton/yr) PM 0.00 PM10 0.00 SO 2 0.00 VOC 0.00 CO 0.00 NO x 0.00 Single HAP <10.0 each HAP Combination HAPs <25.0 (a) This existing source is nota major stationary source because no attainment regulated pollutant is emitted at a rate of 250 tons per year or more, and it is not in one of the 28 listed source categories.
Part 70 Permit Determination 326 IAC 2-7 (Part 70 Permit Program) This existing source is not subject to the Part 70 Permit requirements because the potential to emit (PTE) of: (a) each criteria pollutant is less than 100 tons per year, (b) a single hazardous air pollutant (HAP) is less than 10 tons per year, and (c) any combination of HAPs is less than 25 tons/year. Although this source is subject to the National Emission Standards for Hazardous Air Pollutants (NESHAPs), 326 IAC 14, (40 CFR 63, Subpart N), no Title V permit is required pursuant to 40 CFR 63.340(e). This is the first air approval issued to this source.Biddle Precision Components, Inc.

Federal Rule Applicability (a) There are no New Source Performance Standards (NSPS)(326 IAC 12 and 40 CFR Part 60) applicable to this source. (b) Tanks (CH1, CH2, CH3, CH4, CH5 and CH6) are subject to the National Emission Standards for Hazardous Air Pollutants, 326 IAC 14, (40 CFR 63, Subpart N, and 326 IAC 20-1-1). Pursuant to 40 CFR 63, Subpart N, and 326 IAC 20-1-1, the chromium electroplating operations are subject to the following conditions: (a) The permittee shall comply with the requirements of this condition on and after the compliance date for the tank(s). (b) The hard chromium electroplating tanks, identified as (CH1, CH2, CH3, CH4, CH5 and CH6) above, are considered a small, existing hard chromium electroplating operation. During tank operation, the Permittee shall control chromium emissions discharged to the atmosphere from the hard chromium electroplating tank(s) by not allowing the concentration of total chromium in the exhaust gas stream discharged to the atmosphere to exceed three-hundredths milligrams of total chromium per dry standard cubic meter of ventilation air (0.03 mg/dscm) [equivalent to one and three-tenths times ten raised to the power of negative five grains of total chromium per dry standard cubic foot of ventilation air (1.3x10 -5gr/dscf)]. (c) The surface tension of the chromium electroplating bath contained with the tank shall not exceed forty-five (45) dynes per centimeter at any time during the operation of the tank if a chemical fume suppressant containing a wetting agent is used to demonstrate compliance. Each time that surface tension monitoring exceeds forty-five (45) dynes per centimeter, the frequency of monitoring must revert back to every four (4) hours of tank operation. After forty (40) hours of monitoring tank operation every four (4) hours with no exceedances, surface tension measurement may be conducted once every eight (8) hours of tank operation. Once there have been no exceedances during forty (40) hours of tank operation, surface tension measurement may be conducted once every forty (40) hours of tank operation on an ongoing basis, until an exceedance occurs.

Addendum to the Technical Support Document for New Construction and Operation
Source Name: Biddle Precision Components, Inc. Source Location: 701 South Main Street, Sheridan, IN 46049 County: Hamilton MSOP No.: 057-11705-00048 SIC Code: 3451 Permit Reviewer: Phillip Ritz/EVP On May 11, 2000, the Office of Air Quality (OAQ) had a notice published in the Daily Ledger in Noblesville, Indiana, stating that Biddle Precision Components, Inc. had applied for a construction permit to construct and operate a hard chromium electroplating operation coating steel with control. The notice also stated that OAQ proposed to issue a permit for this installation and provided information on how the public could review the proposed permit and other documentation. Finally, the notice informed interested parties that there was a period of thirty (30) days to provide comments on whether or not this permit should be issued as proposed. Upon further review, the OAQ has decided to make the following revisions to the permit to incorporate updated language for new hard chromium electroplating operations ( boldedlanguage has been added, the language with a linethrough it has been deleted). The Table Of Contents has been modified to reflect these changes. The OAQ has revised the permit to replace the old name of Office of Air Management (OAM) with the new name of the Office of Air Quality (OAQ). (a ) Conditions D.1.1 through D.1.4 in the permit section entitled “Emission Limitations and Standards” have been revised as shown below to: (1)reflect the use of the term “emissions unit” in revised state permitting rules; (2) be more consistent with the language of the Chromium Electroplating NESHAP; (3) delete language that was inadvertently included in the draft permit; and (4) add the requirement to address excess emissions as well as malfunctions if they occur. By this permit, the Permittee is approved to use a composite mesh-pad system as the emission reduction technique to comply with the Chromium Electroplating NESHAP. However, IDEM, OAQ encourages the Permittee to also consider the use of fume suppressants to comply as this technique can achieve a greater degree of emission reductions. Use of fume suppressants can be approved in a permit modification as an alternative means of compliance in addition to or instead of the composite mesh-pad system. Emission Limitations and Standards [326 IAC 2-6.1-5(1)]
D.1.1 General Provisions Relating to HAPs [326 IAC 20-1-1][40 CFR Part 63, Subpart A] The provisions of 40 CFR Part 63, Subpart A - General Provisions, which are incorporated by reference as 326 IAC 20-1-1, apply to the facility described in this section except when otherwise specified in 40 CFR Part 63, Subpart N. The permittee shall comply with the requirements of this condition on and after the compliance date for the tanks.
D.1.2 Chromium Electroplating and Anodizing NESHAP [326 IAC 20-8-1] [40 CFR Part 63, Subpart N] The provisions of 40 CFR 63, Subpart N - National Emission Standards for Chromium Emissions From Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks, which are incorporated by reference as 326 IAC 20-8-1, apply to tanks (CH1, CH2, CH3, CH4, CH5 and CH6). A copy of this rule is attached. The permittee shall comply with the requirements of this condition on and after the compliance date for the tanks .D.1.3 Chromium Emissions Limitation [40 CFR 63.342(c)] [40 CFR 63.343(a)(1)&(2)] (a) The emission limitations in this condition apply only during tank operation, and also apply during periods of startup and shutdown as these are routine occurrences for tanks subject to 326 IAC 20-8-1. The emission limitations do not apply during periods of malfunction. (b) During tank operation, the Permittee shall control chromium emissions discharged to the atmosphere from tanks (CH1, CH2, CH3, CH4, CH5 and CH6) by: (1) Not allowing the concentration of total chromium in the exhaust gas stream discharged to the atmosphere to exceed one-hundredth milligrams of total chromium per dry standard cubic meter of ventilation air (0.01 mg/dscm) [equivalent to four and four-tenths times ten raised to the power of negative six grains of total chromium per dry standard cubic foot of ventilation air (4.4x10 -6 gr/dscf)]. (b) The hard chromium electroplating tanks, identified as tanks (CH1, CH2, CH3, CH4, CH5 and CH6) above, are considered a large, existing hard chromium electroplating operation. During tank operation, the Permittee shall control chromium emissions discharged to the atmosphere from the tank (s)by not allowing the concentration of total chromium in the exhaust gas stream discharged to the atmosphere to exceed 0.015 mg/dscm [6.6x10 -6gr/dscf].
D.1.4 Work Practice Standards [40 CFR 63.342(f)] The following work practice standards apply to tanks (CH1, CH2, CH3, CH4, CH5 and CH6): (a) At all times, including periods of startup, shutdown, malfunction and excess emissions, the Permittee shall operate and maintain tanks (CH1, CH2, CH3, CH4, CH5 and CH6), including the air pollution control techniques (composite mesh pad scrubber) and monitoring equipment, in a manner consistent with good air pollution control practices, consistent with the Operation and Maintenance Plan (OMP) required by Condition D.1.6. (a) Malfunctions and excess emissions shall be corrected as soon as practicable after their occurrence in accordance with the OMP required by Condition D.1.6. (b) These operation and maintenance requirements are enforceable independent of emissions limitations or other requirements in this section. (c) Determination of whether acceptable operation and maintenance procedures are being used will be based on information available to IDEM, OAQ, which may include, but is not limited to, monitoring results; review of the OMP, procedures, and records; and inspection of the source. (d) Based on the results of a determination made under paragraph (d) of this condition, IDEM, OAQ may require that the Permittee make changes to the OMP required by Condition D.1.6. Revisions may be required if IDEM, OAQ finds that the plan: (1) Does not address a malfunction or period of excess emissions that has occurred; (2) Fails to provide for the operation of tanks (CH1, CH2, CH3, CH4, CH5 and CH6), the air pollution control techniques (composite mesh pad scrubber), and process monitoring equipment during a malfunction or period of excess emissions in a manner consistent with good air pollution control practices; or(3) Does not provide adequate procedures for correcting malfunctioning process equipment, air pollution control techniques (composite mesh pad scrubber), monitoring equipment or other causes of excess emissions as quickly as practicable. The work practice standards that address operation and maintenance must be followed during malfunctions and periods of excess emissions. D.1.5 Preventive Maintenance Plan [326 IAC 1-6-3] A Preventive Maintenance Plan (PMP), in accordance with Section B-Preventive Maintenance Plan, of this permit, is required for tanks (CH1, CH2, CH3, CH4, CH5 and CH6) and the air pollution control techniques (composite mesh pad scrubber)

(c) If the OMP fails to address or inadequately addresses an event that meets the characteristics of a malfunction or period of excess emissions at the time the plan is initially developed, the Permittee shall revise the OMP within forty-five (45) days after such an event occurs. The revised plan shall include procedures for operating and maintaining tanks (CH1, CH2, CH3, CH4, CH5 and CH6), the air pollution control device, the add-on air pollution control device and the monitoring equipment, during similar malfunction or period of excess emissions events, and a program for corrective action for such events. (d) If actions taken by the Permittee during periods of malfunction or period of excess emissions are inconsistent with the procedures specified in the OMP, the Permittee shall record the actions taken for that event and shall report by phone such actions within two (2) working days after commencing actions inconsistent with the plan. This report shall be followed by a letter within seven (7) working days after the end of the event, unless the Permittee makes alternative reporting arrangements, in advance, with IDEM, OAQ.(e) The Permittee shall keep the written OMP on record after it is developed to be made available, upon request, by IDEM, OAQ for the life of tanks (CH1, CH2, CH3, CH4, CH5 and CH6) or until the tank is no longer subject to the provisions of 40 CFR 63.340. In addition, if the OMP is revised, the Permittee shall keep previous versions of the OMPs on record to be made available for inspection, upon request by IDEM, OAQ for a period of five (5) years after each revision to the plan. Compliance Determination Requirements [326 IAC 2-1.1-11 ]
D.1.7 Performance Testing [326 IAC 2-1.1-11] [40 CFR 63.343(b)(2)] [40 CFR 63.7] [40 CFR 63.344] (a) A performance test demonstrating initial compliance for tanks (CH1, CH2, CH3, CH4, CH5 and CH6) was performed on October 8, 1996. During the initial performance test, it was determined that the average pressure drop across the composite mesh pad system was 1.2 ±1 inches of water and the average outlet chromium concentration is 0.013 mg/dscm. (b) The Permittee is not required to further test tanks (CH1, CH2, CH3, CH4, CH5 and CH6) by this permit. However, the IDEM may require testing when necessary to determine if the tanks are in compliance. If testing is required by the IDEM, compliance with the limits specified in Condition D.1.3 shall be determined by a performance test conducted in accordance with 40 CFR 63.344 and Section C - Performance Testing. (c) Any change, modification, or reconstruction of tanks (CH1, CH2, CH3, CH4, CH5 and CH6), the air pollution control techniques (composite mesh pad scrubber) or monitoring equipment may require additional performance testing conducted in accordance with 40 CFR 63.344 and Section C - Performance Testing.
