## § 63.343 Compliance provisions.

(a) Compliance dates. (1) The owner or operator of an existi ng affected source shall comply with the emission limitations in §63.342 as follows:CM Grinding, Inc. Page 22 of 38 South Bend, Indiana M 141-21370-00190 Permit Reviewer: Timothy R. Pettifor

(ii) No later than 2 years after January 25, 1995, if t he affected source is a hard chromium electroplating tank or a chromium anodizing tank.

(2) The owner or operator of a new or reconstruct ed affected source that has an initial startup after January 25, 1995, shall comply immediately upon start up of the source. The owner or operator of a new

or reconstructed affected source t hat has an initial startup after December 16, 1993 but before January 25, 1995, shall follow the compliance schedule of §63.6(b)(1).

(3) The owner or operator of an existing area source that increases actual or potential emissions of hazardous air pollutants such that the area source becomes a major source must comply with the provisions for existing major sources, including the reporting provisions of §63.347(g), immediately upon becoming a major source.

(4) The owner or operator of a new area source (i.e., an area source for which construction or reconstruction was commenced after December 16, 1993) that increases actual or potential emissions of hazardous air pollutants such that the area source becomes a major source must comply with the provisions for new major sources, immediately upon becoming a major source.

(5) An owner or operator of an existing hard chromium electroplating tank or tanks located at a small, hard chromium electroplating facility t hat increases its maximum cumulative potential rectifier capacity, or

its actual cumulative rectifier capacity, such that the facility becomes a large, hard chromium electroplating facility must comply with the requir ements of §63.342(c)(1)(i) for all hard chromium electroplating tanks at the facility no later than 1 year after the month in which monthly records required by §§63.342(c)(2) and 63.346(b)(12) sh ow that the large designation is met, or by the compliance date specified in paragraph (a)(1)(ii) of this section, whichever is later.

(6) Request for an extension of compliance. An owner or operator of an affected source or sources that requests an extension of compliance shall do so in accordance with this paragraph and the applicable paragraphs of §63.6(i). When the owner or operato r is requesting the extension for more than one affected source located at the facility, then only one r equest may be submitted for all affected sources at the facility.

(i) The owner or operator of an existing affected source who is unable to comply with a relevant standard under this subpart may request that the Administrator (or a State, when the State has an approved part 70 permit program and the source is required to obtain a part 70 permit under that program, or a State, when the State has been delegated the authority to im plement and enforce the em ission standard for that source) grant an extension allowing the owner or operator up to 1 additional year to comply with the standard for the affected source. The owner or oper ator of an affected source who has requested an extension of compliance under this paragraph and is otherwise required to obtain a title V permit for the source shall apply for such permit or apply to have the title V permit revised to incorporate the conditions of the extension of compliance. The conditions of an extension of compliance granted under this paragraph will be incorporated into the owner or oper ator's title V permit for the affected source(s) according to the provisions of 40 CFR part 70 or 40 CFR part 71, whichever is applicable.

(ii) Any request under this paragraph for an extension of compliance with a relevant standard shall be submitted in writing to the appropriate authority not later than 6 months before the affected source's compliance date as spec ified in this section.

(b) Methods to demonstrate initial compliance.

(1) Except as provided in paragraphs (b)(2) and (b)(3) of this section, an owner or operator of an affected source subject to the requirements of this subpart is required to conduct an initial performance test as required under §63.7, except for hard chromium el ectroplaters and chromium anodizing operations inCM Grinding, Inc. Page 23 of 38 South Bend, Indiana M 141-21370-00190 Permit Reviewer: Timothy R. Pettifor

California which have until January 25, 1998, using th e procedures and test methods listed in §§63.7 and

63.344.

(c) Monitoring to demonstrate continuous compliance. The owner or operator of an affected source subject to the emission limitations of this subpart shall conduct monitoring according to the type of air pollution control technique that is used to comply wi th the emission limitation. The monitoring required to demonstrate continuous compliance with the emission lim itations is identified in this section for the air pollution control techniques expected to be used by the owners or operator s of affected sources.

(5) Wetting agent-type or combination wetting agent-type/foam blanket fume suppressants. (i) During the initial performance test, the owner or operator of an affected source complying with the emission limitations in §63.342 through the use of a wetting ag ent in the electroplating or anodizing bath shall determine the outlet chromium concentration using the procedures in §63.344(c). The owner or operator shall establish as the site-specific operating param eter the surface tension of the bath using Method 306B, appendix A of this part, setting the maximum va lue that corresponds to compliance with the applicable emission limitation. In lieu of establ ishing the maximum surface tension during the performance test, the owner or operator may accept 45 dynes/cm as measured by a stalagmometer or 35 dynes/cm as measured by a tensiometer as the maxi mum surface tension value that corresponds to compliance with the applicable emission limitation. However, the owner or operator is exempt from conducting a performance test only if the criteria of paragraph (b)(2) of this section are met.

(ii) On and after the date on which the initial perfo rmance test is required to be completed under §63.7, except for hard chromium electroplaters and chro mium anodizing operations in California, which have until January 25, 1998, the owner or operator of an affe cted source shall monitor the surface tension of the electroplating or anodizing bath. Operation of the affected source at a surface tension greater than the value established during the performance test, or greater than 45 dynes/cm as measured by a stalagmometer or 35 dynes/cm as measured by a tensio meter if the owner or operator is using this value in accordance with paragraph (c)(5)(i) of this sectio n, shall constitute noncompliance with the standards.

The surface tension shall be monitor ed according to the following schedule:

(A) The surface tension shall be measured once ev ery 4 hours during operation of the tank with a stalagmometer or a tensiometer as specified in Method 306B, appendix A of this part.

(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 exceeda nces 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 subpar t 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 (c)(5)(ii)(B) of this se ction. For example, if an owner or operator had been monitoring an affected source once every 40 hours and an exceedance occurs, subsequent monitoring would take place once every 4 hours of tank operat ion. 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 sc hedule, monitoring can occur once every 40 hours of tank operation.

(iii) Once a bath solution is drained from the affected tank and a new solution added, the original monitoring schedule of once every 4 hours must be re sumed, with a decrease in monitoring frequency allowed following the procedures of paragraphs (c)(5)(ii) (B) and (C) of this section.CM Grinding, Inc.

The sampling time and sample volume for each run of Methods 306 and 306A, appendixCM Grinding, Inc. Page 25 of 38 South Bend, Indiana M 141-21370-00190 Permit Reviewer: Timothy R. Pettifor

A of this part shall be at least 120 minutes and 1. 70 dscm (60 dscf), respectively. Methods 306 and 306A, appendix A of this part allow the measurement of either total chromium or hexavalent chromium emissions. For the purposes of this standard, sources using chromic acid baths can demonstrate compliance with the emission limits of §63.342 by measuring either total chromium or hexavalent chromium. Hence, the hexavalent ch romium concentration measured by these methods is equal to the total chromium concentration for the affected operations.

(2) The California Air Resources Board (CARB) Me thod 425 (which is available by contacting the California Air Resources Board, 1102 Q Street, Sacr amento, California 95814) may be used to determine the chromium concentration from hard and decorative chromium electroplating tanks and chromium anodizing tanks if the following conditions are met:

(i) If a colorimetric analysis method is used, the samp ling time and volume shall be sufficient to result in 33 to 66 micrograms of catch in the sampling train.

(ii) If Atomic Absorption Graphite Furnace (AAGF) or Ion Chromatography with a Post-column Reactor (ICPCR) analyses were used, the sampling time and volume should be sufficient to result in a sample

catch that is 5 to 10 times the minimum detection lim it of the analytical method (i.e., 1.0 microgram per liter of sample for AAGF and 0.5 microg ram per liter of sample for ICPCR).

(iii) In the case of either paragraph (c)(2) (i) or (ii) of th is section, a minimum of 3 separate runs must be conducted. The other requirements of §63.7 that apply to affected sources, as indicated in Table 1 of this subpart, must also be met.

(3) Method 306B, “Surface Tension Measurement and Recordkeeping for Tanks Used at Decorative Chromium Electroplating and Anodizing Facilities,” appendi x A of this part shall be used to measure the surface tension of electroplating and anodizing baths.

(4) When more than one monitoring device is used to comply with the continuous compliance monitoring required by §63.343(c), the owner or operator sha ll report the results as required for each monitoring device. However, when one monitoring device is used as a backup for the primary monitoring device, the owner or operator shall only report the results from the monitoring device used to meet the monitoring requirements of this subpart. If both devices are us ed to meet these requirements, then the owner or operator shall report the results from each monitoring device for the relevant compliance period.

(h) Ongoing compliance status reports for area sources. The requirements of this paragraph do not alleviate affected area sources from complying with th e requirements of State or Federal operating permit programs under 40 CFR part 71.

(1) The owner or operator of an affected source that is located at an area source site shall prepare a summary report to document the ongoing compliance status of the affected s ource. The report shall contain the information identified in paragraph (g)(3) of this section, shall be completed annually and retained on site, and made available to the Administrator upon request. The report shall be completed annually except as provided in par agraph (h)(2) of this section.

(2) Reports of exceedances. (i) If both of the following conditions are met, semiannual reports shall be prepared and submitted to the Administrator:

(A) The total duration of excess emissions (as indicat ed by the monitoring data collected by the owner or operator of the affected source in accordance with §63.343(c)) is 1 percent or greater of the total operating time for the reporting period; and

(B) The total duration of malfunctions of the add-on air pollution control device and monitoring equipment is 5 percent or greater of the total operating time.

(ii) Once an owner or operator of an affected sour ce reports an exceedance as defined in paragraph (h)(2)(i) of this section, ongoing compliance status reports shall be submitted semiannually until a request to reduce reporting frequency under paragr aph (h)(3) of this section is approved.

(iii) The Administrator may determine on a case-by- case basis that the su mmary report shall be completed more frequently and submitted, or that the annual report shall be submitted instead of being retained on site, if these measures are necessary to accurately assess the compliance status of the

source.CM Grinding, Inc. Page 32 of 38 South Bend, Indiana M 141-21370-00190 Permit Reviewer: Timothy R. Pettifor

(3) Request to reduce frequency of ongoing compliance status reports. (i) An owner or operator who is required to submit ongoing compliance status reports on a semiannual (or more frequent) basis, or is required to submit its annual report instead of retainin g it on site, may reduce the frequency of reporting to annual and/or be allowed to maintain the annual report onsite if all of the following conditions are met:

(A) For 1 full year (e.g., 2 semiannual or 4 quarterly reporting periods), the ongoing compliance status reports demonstrate that the affected source is in compliance with the relevant emission limit;

(B) The owner or operator continues to comply with all applicable recordkeeping and monitoring requirements of subpart A of this part and this subpart; and

(C) The Administrator does not object to a redu ced reporting frequency for the affected source, as provided in paragraphs (h)(3) (ii) and (iii) of this section.

(ii) The frequency of submitting ongoing compliance st atus reports may be reduced only after the owner or operator notifies the Administrator in writing of his or her intention to make such a change, and the Administrator does not object to the intended change. In deciding whether to approve a reduced reporting frequency, the Administrator may review informatio n concerning the source's previous performance history during the 5-year recordkeeping period prior to the intended change, or the recordkeeping period since the source's compliance date, whichever is shorter. Records subject to review may include performance test results, monitoring data, and evalua tions of an owner or operator's conformance with emission limitations and work practice standards. Such information may be used by the Administrator to make a judgement about the source's potential for noncompliance in the future. If the Administrator disapproves the owner or operator's request to redu ce reporting frequency, the Administrator will notify the owner or operator in writing within 45 days after re ceiving notice of the owner or operator's intention.

The notification from the Administrator to the owner or operator will specify the grounds on which the disapproval is based. In the absence of a notice of di sapproval within 45 days, approval is automatically granted.

(iii) As soon as the monitoring data required by §63.343(c ) show that the source is not in compliance with the relevant emission limit, the frequency of reporting shall revert to semiannual, and the owner shall state this exceedance in the ongoing compliance stat us report for the next reporting period. After demonstrating ongoing compliance with the relevant emission limit for another full year, the owner or operator may again request approval from the Administra tor to reduce the reporting frequency as allowed by paragraph (h)(3) of this section.

SIC Code: 3471 Operation Permit No.: M 141-11700-00190 Operation Permit Issuance Date: October 2, 2000

Permit Renewal No.: M 141-21370-00190 Permit Reviewer: Timothy R. Pettifor

On December 9, 2006, the Office of Air Qua lity (OAQ) had a notice published in the South Bend Tribune, 225 West Colfax, South B end, Indiana, 46626, stating that CM Grinding, Inc. had applied for a Minor Source Operating Permit (MSOP) Renewal to operate a stationary small hard chromium electroplating source. The notice also stated that OAQ proposed to issue a permit for this operation and provided information on how the public could revi ew 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.

No comments were received. Upon further review, IDEM, OAQ has decided to make the following changes to the permit. The changes listed below have been made to MSOP No.141-21370- 00190. The Table of Contents has been updated . Deleted language appears as strikethroughs and new language appears in bold :

1. The source has added one new open surface hard chrome plating tank. The new open surface hard chrome plating tank is of the same type as the existing open surface hard chrome plating tanks and shall comply with the same applicabl e requirements and permit terms and conditions as the existing tanks. Pursuant to 326 IAC 2-1. 1-3(e)(1)(A) and (H),the new open surface hard chrome plating tank will not result in an increase in potential emissions be low the exemption level.
Condition A.2 and Section D.1 have been revise d to include the third tank as follows:

. The HAP and particulate emissions from electroplating operations have been recalculated, and the table now includes the potential emission s from Tank 3. No changes have been made to the TSD because the OAQ prefers that the Tec hnical Support Document reflect the permit that was on public notice. Changes that occur afte r the public notice are documented in this Addendum to the Technical Support Document. This accomplishes the desired result, ensuring that these types of concerns are documented and part of the record regarding this permit decision. The Potential to Emit (of the Source or Revision) Before Controls and Source Status

have also been revised.

compliance with the applicable emission limitation. In lieu of establishing the maximum surface tension during the performance test, the owner or operator may accept 45 dynes/cm as the maximum surface tension value that corresponds to compliance with the applicable emission limitation. However, t he owner or operator is exempt from conducting a performance test only if the cr iteria of paragraph (b)(2) of this section are met.

(ii) On and after the date on which the initial performance test is required to be completed under Sec. 63.7, the owner or operator of an affected source shall monitor the surface tension of the electroplating or an odizing bath. Operation of the affected source at a surface tension grea ter than the value established during the performance test, or greater than 45 dynes/cm if the owner or operator is using this value in accordance with paragraph (c)(5)(i) of this section, shall constitute noncompliance with the standard s. The surface tension shall be monitored according to the following schedule:

(A) The surface tension shall be m easured 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.

(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 opera tion 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 ther e are no exceedances during 40 hours of tank operation, su rface tension measurement may be conducted once every 40 hours of tank operation on an ongoing basis, until an excee dance occurs. The minimum frequency of monitoring allowed by this subpart is once every 40 hours of tank operation.

(C) Once an exce edance occurs as indicated through surface tension monitoring, the original monitoring schedule of once ev ery 4 hours must be resumed. A subsequent decrease in frequency shall follow the schedule laid out in paragraph (c)(5)(ii)(B) of this

section . For example, if an owner or operator had been monitoring an affected source once every 40 hours and an exceedance occurs, subsequent monitoring would take place once every 4 hours of tank operati on. 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.

Potential to Emit (of the Source or Revision) Before Controls

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 it s physical and operational design. Any physical or operational limitation on t he capacity of a source to emit an air pollutant, inclulding air pollution control equipment and restrict ions 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 t he appropriate local air pollution control agency.”CM Grinding, Inc.

(a) The potential to emit (as defined in 326 IAC 2-7- 1(29)) of each critera pollutant is less than 100 tons per year. 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. An MSOP

will be issued.

(b) Pursuant to 326 IAC 2-5.1-3(a)(2)(A), the existing source is subject to 326 IAC 2-6.1 (MSOP) because it consists of hard chromium electroplating tanks and it is subject to 326

IAC 20-8.

(c) Fugitive Emissions Since this type of operation is not one of t he twenty-eight (28) listed source categories under 326 IAC 2-2 and since there are no appl icable New Source Performance Standards that were in effect on August 7, 1980, t he fugitive emissions are not counted toward determination of PSD and Emission Offset applicability.

Quality Standards (NAAQS) for ozone. T herefore, VOC and NOx emissions are considered when evaluating the rule applic ability relating to the ozone standards. St Joseph County has been designated as nonattainment for the 8-hour ozone standard. Therefore, VOC and NOx emissions were reviewed pursuant to the requirements for

Emission Offset. See the State Rule A pplicability – Entire Source section.

(b) St. Joseph County has been classified as attainme nt or unclassifiable for PM-10, SO 2 , NO 2 , Ozone under the one hour standard, CO, an d Lead. Therefore, these emissions were reviewed pursuant to the requirements for Prevention of Significant Deterioration (PSD), 326 IAC 2-2. See the State Rule Applicability – Entire Source section.

(c) St. Joseph County has been classified as attainment for PM2.5. U.S. EPA has not yet established the requirements for Prevention of Significant Deterioration (PSD), 326 IAC 2- 2 for PM 2.5 emissions. Therefore, until the U.S.EPA adopts specific provisions for PSD review for PM2.5 emissions, it has direct ed states to regulate PM10 emissions as surrogate for PM2.5 emissions. See the State Ru le Applicability – Entire Source section.

(d) Fugitive Emissions Since this type of operation is not one of t he 28 listed source categories under 326 IAC 2- 2 or 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) This existing source is not a major st ationary source because no attainment regulated pollutant is emitted at a rate of 250 tons per year or greater, no nonattainment regulated pollutant is emitted at a rate of 100 tons per year or greater, and it is not in one of the 28 listed source categories.

(b) These emissions were based on the emission calculations in Appendix A to this

document.

Part 70 Permit Determination

326 IAC 2-7 (Part 70 Permit Program) This existing source, including the emissions fr om this permit 141-21370-00190, 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,CM Grinding, Inc. Page 5 of 9 South Bend, Indiana TSD to 141-21370-00190

Permit Reviewer: Jed D. Wolkins

(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 per year.

This status is based on all the air approvals issued to the source.

Federal Rule Applicability

(a) There are no New Source Performance Standards (NSPS) (326 IA C 12 and 40 CFR Part 60) included in this permit.

(b) The requirements of the National Emission Standards for Hazardous Air Pollutants (NESHAP), Subpart DDDDD are not included in this permit, due to the source being an

area source of HAPs.

(c) This source is subject to the National Emission Standards for Hazardous Air Pollutants, 326 IAC 20-8, (40 CFR 63.340, Subpart N).

(d) The hard chrome electroplating tanks, identif ied as Tank 1 and Tank 2, are subject to the
National Emission Standards for Hazardous Ai r Pollutants, 326 IAC 20-8, (40 CFR 63.340, Subpart N).

The hard chrome electroplating tanks, identifi ed as Tank 1 and Tank 2, are subject to the following portions of Subpart N

. Non applicable portions of the NESHAP will not be included in the permit

. The hard chrome electroplating tanks, identified as Tank 1 and Tank 2, are open surface hard chromium electroplating tanks, located at a small, hard chromium electroplating facility. The Permitt ee uses a fume suppressant for control. The surface tension is measured to show compliance. The Permittee tested the tanks on May 27 to May 29, 1997. The testing developed the upper limit on surface tension as 49.9 dynes per centimeter at Tank 1 and 48.4 dynes per centimeter at Tank 2. The Permittee has conducted all initial testing and notifications.

Pursuant to 40 CFR 63.340(e)(2), a source subj ect to Subpart N is also subject to the Title V permitting requirements. IDEM, OAQ, has granted a deferral under this rule until December 9, 2004, for sources that are not located at a major and are not otherwise required to obtain a Title V permit. Therefore, the Permittee must submit a Title V permit application by December 9, 2005. On March 25, 2005, the U.S. EPA proposed to exempt all sources that are subject to a NESHAP, but are not major sources from Title V permitting requirements. If that rule becomes final, the Permittee will not be required to submit a Title V permit application.

Non applicable portions of the NESHAP will not be included in the permit. The hard chrome electroplating tanks, identified as Tank 1 and Tank 2, are subject to the following portions of Subpart N.

The provisions of 40 CFR 63 Subpart A – Gene ral Provisions, which are incorporated as 326 IAC 20-1-1, apply to the facility described in this section except when otherwise specified in 40 CFR 63 Subpart N.

State Rule Applicability – Entire Source

326 IAC 1-5-2 (Emergen cy Reduction Plans) The source is not required to submit an Emergency Reduction Plan.

326 IAC 1-6-3 (Preventiv e Maintenance Plan) (a) If required by specific condition(s) in Secti on D of the permit, the Permittee shall maintain and implement Preventive Maintenance Plans (PMPs) including the following information on each facility:

(1) Identification of the individual(s) res ponsible for inspecting, maintaining, and repairing emission control devices;

(2) A description of the items or conditions that will be inspected and the inspection schedule for said items or conditions; and

(3) Identification and quantific ation of the replacement pa rts that will be maintained in inventory for quick replacement.

(b) A copy of the PMPs shall be submitted to IDEM, OAQ, upon request and within a reasonable time, and shall be subject to review and approval by IDEM, OAQ. IDEM, OAQ, may require the Permittee to revise its PMPs whenever lack of proper maintenance causes or is the primary contributor to an exceedance of any limitation on emissions or potential to emit. The PMP does not require t he certification by the “responsible official” as defined by 326 IAC 2-7-1(34).

326 IAC 1-7-3 (Actual Stack Height Provisions) The current stacks at the source are not subjec t to the provisions of 326 IAC 1-7-3, since the source has less than twenty-five (25) tons per year of potential emissions of PM and SO 2

.

326 IAC 2-2 (Prevention of Significant Deterioration) The total source potential emissions of PM, PM-10, SO 2 , VOC, NO

x , CO, and Lead are less than 250 tons per year. The source is not one of t he 28 listed sources. There are no applicable New
Source Performance Standards that were in effect on August 7, 1980. The source was constructed prior to December 16, 1993. The source has not conducted any modifications to trigger PSD and is currently considered a minor PSD source. Therefore the requirements of 326 IAC 2-2 (Prevention of Significant Deterioration) do not apply.

326 IAC 2-3 (Emission Offset) The total source potential emissions of NOx is less than 100 tons per year. The total source potential emissions of VOC is less than 100 tons per year. The source is not one of the 28 listed sources. There are no applicable New Source Pe rformance Standards that were in effect on August 7, 1980. The source was constructed pr ior to December 16, 1993. The source has not conducted any modifications to trigger Emissi on Offset and is currently considered a minor Emission Offset source. Therefore the require ments of 326 IAC 2-3 (Emission Offset) do not apply.CM Grinding, Inc. Page 8 of 9 South Bend, Indiana TSD to 141-21370-00190

Permit Reviewer: Jed D. Wolkins

326 IAC 2-4.1 (Major Sources of Hazardous Air Pollutants (HAP)) The potential to emit each individual hazardous air pollutant (HAP) is less than 10 tons per year and the potential to emit any combination of HAPs is less than 25 tons per year. Therefore, this source 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, and the requirements of 326 IAC 2-4.1-1, New Source Toxics Control, are not applicable.

326 IAC 2-6 (Emission Reporting) This source is located in St. Joseph County and is not required to have a Part 70 Permit. Therefore, 326 IAC 2-6 does not apply.

326 IAC 2-6.1 (Minor Source Operating Permit Program) This existing source is not subject to the Pa rt 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 per year.

The source consists of hard chromium electropla ting tanks. Therefore, pursuant to 326 IAC 2-5.1- 3(a)(2)(A), the Permittee is subjecto to 326 IAC 2-6.1 (Minor Source Operating Permit Program).

326 IAC 5-1 (Opacity Limitations)

The source is located north of Kern Road and east of Pine Road in St. Joseph county. 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 thir ty percent (30%) in 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 non-overlapping integrated averages for a continuous opacity monitor) in a six (6) hour period.

326 IAC 6-4 (Fugitive Dust Emissions) This source is not a source of Fugitive Dust. Ther efore, this source is not subject to 326 IAC 6-4. The privisous permit incorrectly included the requi rement. If the Permittee added any source of Fugitive Dust it would be subject to 326 IAC 6-4.

326 IAC 6-5 (Fugitive Particulate Matter Emission Limitations) This source is not a source of Fugitive Dust. Ther efore, this source is not subject to 326 IAC 6-5.

State Rule Applicability – Individual Facilities

326 IAC 6.5 (Particulate Matter Limitations Except Lake County) St Joseph County is listed in 326 IAC 6.5-1-1 (a). However, neither the source nor the facilities

are listed in 326 IAC 6.5-7 The source does not have the potential to emit one hundred (100) tons or more nor have actual emissions of ten ( 10) tons or more of par ticulate matter per year

. Therefore, the hard chrome electr oplating tanks, identified as Tank 1 and Tank 2, are exempt for
326 IAC 6.5.

Permit Reviewer: Jed D. Wolkins

The limits in 326 IAC 20-8 for the hard chrome elec troplating tanks, identified as Tank 1 and Tank 2, are more stringent that the limits in 326 IAC 6-3. Therefore, the hard chrome electroplating tanks, identified as Tank 1 and Tank 2, ar e not subject to the limit in 326 IAC 6-3.

326 IAC 20-8-1 (Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks) The hard chrome electroplating tanks, identified as Tank 1 and Tank 2, are subject to 326 IAC 20- 8-1 (Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks). 326 IAC 20- 8 incorporates by reference 40 CFR 63 Subpart N. The Permittee will comply with the provisions of 40 CFR 63 Subpart N as detailed in the Federal Rule Applicability section above.

Subpart N was revised on July 19, 2004. However, pursuant to 326 IAC 1-1-3, the version of the rule referenced by 326 IAC 20-8 was the version in existence on July 1, 2002, which had been most recently amended on December 14, 1999. T herefore, the July 19, 2004, amendents to the federal rule are not approved into the 326 IAC, and the chromium electroplating facilities at this source are subject to both versions of the rule. When the revised rule is incorporated into the 326 IAC, the Permittee may apply for a revision to t he permit to remove any requirements from the previous version of the rule that are not present in the updated version of the rule. All of the requirements of 326 IAC 20-8 rule that are appl icable to this source are the same as the requirements listed under Federal Rule Applicability except for the following:

(1) 40 CFR 63.342 (f)(2)(ii)(B). (2) 40 CFR 63.343 (c)(5)(i). (3) 40 CFR 63.343 (c)(5)(ii). (4) 40 CFR 63.347 (c)(1)(viii).

The 326 IAC version of 40 CFR 63.342 (f)(2)(ii)(b) a llowed IDEM to require the Permittee revise the Operation and Maintence Plan if the plan failed to provide for the operation of the equipment. The new version allows IDEM to require the Perm ittee revise the Operation and Maintence Plan if the plan failed to provide for the proper operation of the equipment. Both will be included in the permit.

The 326 IAC versions of 40 CFR 63.343 (c)(5)(i) and (ii) had a single tension limit of 45 dynes per centimeter (dynes/cm). The new version has tension limits tension limits of 45 dynes per centimeter (dynes/cm), when measured usin g a stalagmometer, and 35 dynes/cm, when measured using a tensiometer. Both will be included in the permit.

The 326 IAC version of 40 CFR 63.347 (c)(1)(viii) stated “sources performing hard chromium electroplating tanks.” The new version states “s ources performing hard chromium electroplating.” The change clarifies that sources do not preform tanks. The requ irement of the paragraph has not changed. Both will be included in the permit.

Testing Requirements

The Permittee has tested as required by 40 CFR 63 Subpart N. The Permittee will not be required to retest by this permit.
