Source Name: Modern Hard Chrome of Indiana, Inc. Source Location: 3550 Canal Street, East Chicago, Indiana 46312 County: Lake Construction Permit No.: MSOP 089-11566-00385 SIC Code: 3471 Permit Reviewer: Peter E. Fountaine/ CarrieAnn Ortolani

On June 8, 2000, the Office of Air Management (OAM) had a notice published in the Gary Post Tribune, Gary, Indiana, stating that Modern Hard Chrome of Indiana, Inc. had applied for a permit to operate a stationary hard chromium electroplating and polishing source with packed bed scrubber/composite mesh pad systems as control. The notice also stated that OAM 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 OAM has decided to make the following changes to the construction permit: The permit language is changed to read as follows (deleted language appears as strikeouts , new language is bolded) :

1. The rectifier capacity of Tank #2 should be 12,500 amperes instead of 12,000 amperes. The facility description in Section A.2 and in the Emissions Unit Description box in Section D.1 has been revised as follows: (b) One(1) three thousand five hundred (3,500) gallon large hard chromium electroplating tank, identified as Tank #2, constructed prior to December 1993, with a rectifier capacity of twelve thousand five hundred (12,000) (12,500) amperes and a maximum rectifier capacity of seventymillion five hundred sixty thousand (70,560,000) ampere-hours per year (A-hr/yr), using apacked bed scrubber/composite mesh pad system as control, and exhausting through stack #1.

2. Since

this is not a New Source Construction Permit, the title on the first page of the permit has been revised as follows:

Enforcement Issue There are no enforcement actions pending.
Recommendation Thestaff 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 November 29, 1999, with additional information received on March 6, 2000 and May 23, 2000. Emission Calculations Chromium emissions (Single HAP) from the largest chromium electroplating source in Indiana are less than ten (10) tons per year and Modern Hard Chrome of Indiana, Inc. is a much smaller source in comparison. Therefore, no emission calculations were necessary for the chromium electroplating because the chromium emissions from this source will be less than ten (10) tons per year. See page 1 of 1 of Appendix A for detailed emission calculations for the combustion operations.Modern Hard Chrome of Indiana, Inc. Page 3 of 9

East Chicago, Indiana MSOP 089-11566-00385 Permit Reviewer: PEF/MES

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 pollu tion 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.”

Therefore, the source is not subject to the provisions of 326 IAC 2-7. (b) 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.Modern Hard Chrome of Indiana, Inc. Page 4 of 9

(c) 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 is not a decorative coating plant. The source is a hard chromium electroplating source and the source emits less than major source levels (see (a) and (b) 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.

Pollutant Status PM 10 moderate nonattainment SO 2 primary nonattainment NO x severe nonattainment Ozone severe nonattainment CO unclassifiable attainment Lead attainment (a) Volatile organic compounds (VOC) and oxides of nitrogen (NO X) are precursors for the formation of ozone. Therefore, VOC and NO X emissions are considered when evaluating the rule applicabilityrelating to the ozone standards. Lake County has been designated as severe nonattainment for ozone. Therefore, VOC and NO X emissions were reviewed pursuant to the requirements for Emission Offset, 326 IAC 2-3. (b) Lake

County has been classified as nonattainment for PM 10 and sulfur dioxide (SO 2 ). Therefore, these emissions were reviewed pursuant to the requirements for Emission Offset, 326 IAC 2-3. (c) Lake

County has been classified as attainment for lead. Therefore, these emissions were reviewed pursuant to the requirements for Emission Offset, 326 IAC 2-3. (d) Pursuant to 40 CFR 81.315, this source, located in Lake County, is within an area designated as unclassifiable attainment for CO

. (e) Fugitive Emissions Since this type of operation is not one of the twenty-eight (28) listed source categories under 326IAC 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.

(a) no nonattainment pollutant is emitted at a rate of one hundred (100) tons per year or greater, (b) the potential to emit volatile organic compounds (VOC) and oxides of nitrogen (NO X) areless than twenty-five (25) tons per year, (c) the potential to emit lead is less than five (5) tons per year, (d) and it is not in one of the twenty-eight (28) listed source categories. Therefore, pursuant to 326 IAC 2-2 and 2-3, and 40 CFR 52.21, the PSD and Emission Offset requirements do not apply. Part 70 Permit Determination 326 IAC 2-7 (Part 70 Permit Program) This new source is not subject to the Part 70 Permit requirements because the potential to emit (PTE) of: (a) PM 10 , SO 2 , and CO is less than one hundred (100) tons per year, (b) VOC and NO X

is less than twenty-five (25) tons per year, (c) a single hazardous air pollutant (HAP) is less than ten (10) tons per year, and (d) any combination of HAPS is less than twenty-five (25) tons per year. This is the first air approval issued to this source. 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) Tank #1 and Tank #2 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). A copy of this rule is attached. Pursuant to 40 CFR 63, Subpart N, and 326 IAC 20-1-1, the chromium electroplating operations are subject to the following conditions: (1) Emission limitation: ThePermittee shall comply with the requirements of this condition on and after the compliance date for the tanks. Thehard chromium electroplating tanks, identified as Tank #1 and Tank #2, are considered a large, existing hard chromium electroplating operation. During tank operation, the Permittee shall control chromium emissions discharged tothe atmospherefrom 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)].Modern Hard Chrome of Indiana, Inc. Page 7 of 9

East Chicago, Indiana MSOP 089-11566-00385 Permit Reviewer: PEF/MES

(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. Eachtime 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. (3) Reporting Requirements: A summary report shall be prepared to document the ongoing compliance status of the chromium electroplating operation. This report shall be completed annually, retained on site, and made available to IDEM upon request. If there are significant exceedance of chromium air emission limits (as defined in 40 CFR Part 63.347 (h)(2)), then semiannual reports shall be submitted to: Indiana Department of Environmental Management Air Compliance Branch, Office of Air Management Chromium Electroplating 100 North Senate Avenue, P.O. Box 6015 Indianapolis, Indiana 46206 (4) Thechromium electroplating operations shall be subject to the record keeping and reporting requirement as indicated in the chromium electroplating NESHAP. State Rule Applicability - Entire Source 326 IAC 2-3 (Emission Offset Minor Source Status) Since the total source potential to emit is less than twenty-five (25) tons per year of each criteria pollutant, the requirements of 326 IAC 2-3 (Emission Offset) will not apply. 326 IAC 2-6 (Emission Reporting) This source is located in Lake County and the potential to emit volatile organic compounds (VOC) and oxides of nitrogen (NO X) are less than ten (10) tons per year. Therefore, 326 IAC 2-6 does not apply.Modern Hard Chrome of Indiana, Inc. Page 8 of 9

East Chicago, Indiana MSOP 089-11566-00385 Permit Reviewer: PEF/MES
326 IAC 5-1 (Opacity Limitations) Pursuant to 326 IAC 5-1-2 (Opacity Limitations), except as provided in 326 IAC 5-1-3 (Temporary Exemption Alternative Opacity Limitations), opacity shall meet the following, unless otherwise stated in this permit: (a) Opacityshall not exceed an average of twenty percent (20%) 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. 326 IAC 6-4 (Fugitive Dust Emissions) Under no circumstance shall the source emit particulate matterto the extent that some visible portion of the material escapes beyond the property line or boundaries of the property, right-of-way, or easement on which the source is located. State Rule Applicability - Individual Facilities 326 IAC 6-1 (Nonattainment area particulate limitations) Since there are no facilities that have the potential to emit one hundred (100) tons or more of particulate matterper year or have actual emissions of ten (10) tons or more of particulate matter per year, the requirements of 326 IAC 6-1 do not apply. 326 IAC 6-2-4 (Particulate Matter Emission Limitations for Sources of Indirect Heating constructed after September 21, 1983) Theone (1) insignificant boiler must comply with the allowable particulate matter emission rate specified by the following equation:

or 0.6 pounds per million British thermal units, whichever is less Pt ' 1

. 09 Q 0

. 26 Where: Pt = Pounds of particulate matter emitted per million British thermal unit (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 the maximum capacityat which the facility is operated or the nameplate capacity, whichever is specified in the facility's permit application, except when some lower capacity is contained in the facility's operation permit; in which case, the capacity specified in the operation permit shall be used. (1.38 million British thermal unit per hour) Since the equation above results in 1.0 pound per million British thermal units, the boiler will be limited to allowable PM emission rate of 0.6 pounds per million British thermal units. The potential particulate matter emissions of the boiler is shown on page 1 of 1 of TSD Appendix A and is as follows:Modern Hard Chrome of Indiana, Inc. Page 9 of 9

East Chicago, Indiana MSOP 089-11566-00385 Permit Reviewer: PEF/MES

Pt = (((0.0115 ton of PM per year * 2000 pounds per ton) / (8760 hours per year)) / (1.38 MMBtu perhour)) = 0.00190 pounds of particulate matter per million British thermal unit. Therefore, the boiler will comply with this rule. 326 IAC 7-1.1 (Sulfur Dioxide Emission Limitations)
Thesource is not subject to this rule since the potential sulfur dioxide emissions from each facility are less than twenty-five (25) tons per year. Air Toxic Emissions Indianapresently requests applicants to provide information on emissions of the 188 hazardous air pollutants (HAPs) set out in the Clean Air Act Amendments of 1990. These pollutants are either carcinogenic or otherwise considered toxic and are commonly used by industries. They are listed as air toxics on the Office of Air Management (OAM) Construction Permit Application Form Y. (a) Thissource will emit levels of air toxics less than those which constitute a major source according to Section 112 of the 1990 Clean Air Act Amendments. (b) See page 1 of 1 of TSD Appendix A for detailed air toxic calculations. (c) Chromium emissions (Single HAP) from the largest chromium electroplating source in Indiana areless than ten (10) tons per year and Modern Hard Chrome of Indiana, Inc. is a much smaller source in comparison. Therefore, no emission calculations were necessary for the chromium electroplating because the chromium emissions from this source will be less than ten (10) tons per year. See page 1 of 1 of Appendix A for detailed emission calculations for the combustion operations. Conclusion Theoperation of this hard chromium electroplating and polishing source shall be subject to the conditions of the attached proposed Minor Source Operating Permit MSOP 089-11566-00385.Appendix A: Emissions Calculations Page 1 of 1 TSD App A Natural Gas Combustion Only MMBtu/hr <100 Company Name: Modern Hard Chrome of Indiana, Inc.

Methodology: All emission factors are based on normal firing. MMBtu = 1,000,000 Btu MMCF = 1,000,000 Cubic Feet of Gas Potential Throughput (MMCF) = Heat Input Capacity (MMBtu/hr) x 8,760 hrs/yr x 1 MMCF/1,000 MMBtu Emission Factors are from AP 42, Chapter 1.4, Tables 1.4-1, 1.4-2, 1.4-3, SCC #1-02-006-02, 1-01-006-02, 1-03-006-02, and 1-03-006-03 (SUPPLEMENT D 3/98) Emission (tons/yr) = Throughput (MMCF/yr) x Emission Factor (lb/MMCF)/2,000 lb/ton Note: Check the applicable rules and test methods for PM and PM10 when using the above emission factors to confirm that the correct factor is used (i.e., condensible included/not included) The five highest organic and metal HAPs emission factors are provided above. Additional HAPs emission factors are available in AP-42, Chapter 1.4.
