The Permittee is exempt from conducting a performance test only if the criteria of 40 CFR 63.343(b)(2) are met. Compliance Monitoring Requirements [326 IAC 2-6.1-5(a)(2)]
D.2.9 Monitoring to Demonstrate Continuous Compliance [326 IAC 2-6.1-5(a)(2)] [40 CFR 63.343(c)] [326 IAC 20-8-1] (a) Pursuant to 40 CFR 63.343(c)(5)(ii) and (iii), when using a wetting agent in the electroplating bath to comply with the limit specified in Condition D.2.3, the Permittee shall monitor the surface tension of the electroplating baths. Operation of tanks #04 and #05 at a surface tension greater than the value established during a performance test shall constitute noncompliance with the standards. Operation of tanks #04 and #05 at a surface tension greater than 45 dynes per centimeter shall constitute noncompliance with the standards. (1) The Permittee shall monitor the surface tension of the electroplating bath during tank operation according to the following schedule: (A) The surface tension shall be measured once every 4 hours during operation of the tank with a stalagmometer or a tensiometer as specified in Method 306B, appendix A of this part.K & I Hard Chrome, Inc.

New Albany, Indiana MSOP 043-11884-00052 Permit Reviewer: NH/EVP Page 28 of 49

(B) The time between monitoring can be increased if there have been no exceedances. The surface tension shall be measured once every 4 hours of tank operation for the first 40 hours of tank operation after the compliance date. Once there are no exceedances during 40 hours of tank operation, surface tension measurement may be conducted once every 8 hours of tank operation. Once there are no exceedances during 40 hours of tank operation, surface tension measurement may be conducted once every 40 hours of tank operation on an ongoing basis, until an exceedance occurs. The minimum frequency of monitoring allowed by this subpart is once every 40 hours of tank operation. (C) Once an exceedance occurs as indicated through surface tension monitoring, the original monitoring schedule of once every 4 hours must be resumed. A subsequent decrease in frequency shall follow the schedule laid out in paragraph (B) above. For example, if a Permittee had been monitoring a tank once every 40 hours and an exceedance occurs, subsequent monitoring would take place once every 4 hours of tank operation. Once an exceedance does not occur for 40 hours of tank operation, monitoring can occur once every 8 hours of tank operation. Once an exceedance does not occur for 40 hours of tank operation on this schedule, monitoring can occur once every 40 hours of tank operation. (2) Once a bath solution is drained from tanks #04 and #05 and a new solution added, the original monitoring schedule of once every 4 hours must be resumed, with a decrease in monitoring frequency allowed following the procedures in paragraphs (B) and (C) above. (b) Tank operation or operating time is defined as that time when a part is in the tank and there is a current running through the tank. If the amount of time that no part is in the tank is fifteen minutes or longer, that time is not considered operating time. Likewise, if the amount of time between placing parts in the tank (i.e., when no part is in the tank) is less than fifteen minutes, that time between plating the two parts is considered operating time.

Office of Air Quality Addendum to the Technical Support Document for a Minor Source Operating Permit (MSOP)

Source Name: K & I Hard Chrome, Inc. Source Location: 1900 E. Main Street, New Albany, IN 47150 SIC Code: 3471 County: Floyd Operation Permit No.: MSOP 043-11884-00052 Permit Reviewer: NH/EVP On December 12, 2000, the Office of Air Quality (OAQ) had a notice published in the New Albany Tribune, New Albany, Indiana, stating that K & I Hard Chrome, Inc. had applied for a Minor Source Operating Permit (MSOP) to operate a hard and decorative chromium electroplating facility. The notice also stated that OAQ proposed to issue a MSOP for this operation and provided information on how the public could review the proposed MSOP 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 MSOP should be issued as proposed. On January 15, 2001, Robert A. Eckerle, President of K & I Hard Chrome, Inc. submitted comments on the proposed MSOP. The summary of the comments and corresponding responses is as follows ( bolded language has been added, the language with a line through it has been deleted):
Comment # 1 An inadvertent mistake was made in the application of our air permit MSOP 043-11884-00052, it was mistakenly reported on Form L (Degreasing operation) that our solvent consumption was 18.3 gals/day when, in fact that was pounds per day. This calculates out to an actual consumption rate of 1.5 gals/day. Response # 1 40 CFR Part 63, Subpart T applies to a degreasing operation based on the type of solvent regardless of the quantity of the solvent used. 40 CFR Part 63, Subpart T applies to each individual batch vapor cleaning open top degreaser operation which uses any solvent containing trichloroethylene as a cleaning agent. K & I uses reclaimed trichloroethylene in its open top degreaser. No changes have been made to the permit as a result of this comment. Upon further review, the OAQ has decided to make the following revisions to the permit: 1) The Part 70 permit has been revised to reflect the name change of the Office of Air Management (OAM) to the Office of Air Quality (OAQ). 2) The expiration date has been added to the signature box.Page 1 of 10

Enforcement Issue Any chrome electroplating source that consists of a chromium electroplating tank, chromium anodizing tank, or an operation subject to 326 IAC 20-8 shall apply for approval under this rule no later than December 27, 1999. K & I Hard Chrome, Inc. submitted their application on January 19,K & I Hard Chrome, Inc. Page 3 of 10

New Albany, Indiana MSOP 043-11884-00052 Permit Reviewer: NH/EVP 2000. IDEM is aware of this and will take appropriate action.
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. An application for the purposes of this review was received on January 19, 2000, with additional information received on March 22, 2000 and August 28, 2000.
Emission Calculations See Appendix A of this document for detailed emissions calculations (Appendix A, page 1). Chromium emissions (Single HAP) from the biggest source in Indiana is less than ten (10) tons per year and K & I Hard Chrome, 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 0.05 PM-10 0.19 SO 2 0.02 VOC 0.14 CO 2.10 NO x 2.50

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 of 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) The existing source is subject to 326 IAC 20-8 but not subject to 326 IAC 2-5.5-1(b)(2) (registration) because the source uses hexavalent chromium for decorative coating instead of trivalent chromium 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).K & I Hard Chrome, Inc. Page 4 of 10

New Albany, Indiana MSOP 043-11884-00052 Permit Reviewer: NH/EVP Actual Emissions No previous emission data has been received from the source.

County Attainment Status The source is located in Floyd County.

Pollutant Status PM-10 attainment SO 2 attainment NO 2 attainment Ozone moderate nonattainment CO attainment Lead attainment (a) Volatile organic compounds (VOC) and oxides of nitrogen are precursors for the formation of ozone. Therefore, VOC and NOx emissions are considered when evaluating the rule applicability relating to the ozone standards. Floyd County has been designated as nonattainment for ozone. Therefore, VOC and NOx emissions were reviewed pursuant to the requirements for Emission Offset, 326 IAC 2-3. (b) Floyd County has been classified as attainment for all other criteria pollutants. Therefore, these emissions were reviewed pursuant to the requirements for Prevention of Significant Deterioration, 326 IAC 2-2. (c) Fugitive Emissions Since this type of operation is not one of the 28 listed source categories under 326 IAC 2- 2, 40 CFR 52.21, or 326 IAC 2-3 and since there are no applicable New Source Performance Standards that were in effect on August 7, 1980, the fugitive particulate matter (PM) and volatile organic compound (VOC) emissions are not counted toward determination of PSD and Emission Offset applicability. 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 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, including the emissions from this permit MSOP 043-11884-00052, is still 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. This status is based on all the air approvals issued to the source. This status has been verified by the OAM inspector assigned to the source. Federal Rule Applicability (a) The one (1) natural gas fired boiler identified as Main Boiler, is not subject to the requirements of the New Source Performance Standard, 326 IAC 12, (40 CFR 60, Subpart Dc), because the boiler capacity is less than 10 MMBtu per hour. (b) Tanks #31, #32, #33, #41, #42, #43, #44, #45, #46, #04 and #05 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: (1) The permittee shall comply with the requirements of this condition on and after the compliance date for the tank. (A) Hard chromium electroplating facilities with a maximum cumulative rectifier capacity greater than 60 million Ampere-hours are considered large. Tanks that were constructed on or before January 25, 1995 are considered existing hard chromium electroplating tanks. (i) The hard chromium electroplating tanks, identified as #41, #42, #43, #44, #45 and #46 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 tanks by not allowing the concentration of total chromium in the exhaust gas stream discharged to the atmosphere to exceed fifteen-thousandth milligrams of total chromium per dry standard cubic meter of ventilation air (0.015 mg/dscm) [equivalent to six and six-tenths times ten raised to the power of negative six grains of total chromium per dry standard cubic foot of ventilation air (6.6x10 -6 gr/dscf)]. (ii) The hard chromium electroplating tanks, identified as #31, #32 and #33 above, are considered a small, existing hard chromium electroplating operation.

New Albany, Indiana MSOP 043-11884-00052 Permit Reviewer: NH/EVP shall control chromium emissions discharged to the atmosphere from the hard chromium electroplating tanks 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 -5 gr/dscf)].

(B) During tank operation, the Permittee shall control chromium emissions discharged to the atmosphere from tanks #04 and #05 by: (i) Not allowing the concentration of total chromium in the exhaustgas stream discharged to the atmosphere to exceed onehundredth milligrams of total chromium per dry standard cubicmeter of ventilation air (0.01 mg/dscm) [equivalent to four and fourtenths 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)]; or (ii) Not allowing the surface tension of the anodizing bath contained within the tank to exceed forty-five dynes per centimeter (45 dynes/cm) [equivalent to three and one-tenth times ten raised to the power of negative three pound-force per foot (3.1x10 -3 lb f /ft)] at any time during operation of tanks #04 and #05 when a chemical fume suppressant containing a wetting agent is used. (iii) Not allowing the foam blanket thickness of the anodizing bath contained within the tank to be less than two and fifty-four hundredths centimeters (2.54 cm) [equivalent to one inch (1 in)] at any time during operation of tanks #04 and #05 when a foam blanket is used. (2) Monitoring Requirements 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. An alternative emission limit of 0.01 milligram per day standard cubic meter (mg/dscm) will be applicable if the chromium electroplating bath does not meet the limit above.K & I Hard Chrome, Inc.
