schedule is based on operating 24 hours per day, 7 days per week, 50 weeks per year. 

Open surface hard chromium electroplating tank means a chromium electroplating tank that is ventilated 

at a rate consistent with good ventilation practices for open tanks. 

Operating parameter value means a minimum or maximum value established for a control device or 

process parameter which, if achieved by itself or in combination with one or more other operating 

parameter values, determines that an owner or operator is in continual compliance with the applicable

§ 63.343 Compliance provisions. 

(a) Compliance dates. (1) The owner or operator of an existing 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 the affected source is a hard chromium electroplating 

tank or a chromium anodizing tank. 

(2) The owner or operator of a new or reconstructed affected source that has an initial startup after 

January 25, 1995, shall comply immediately upon startup of the source. The owner or operator of a new 

or reconstructed affected source that 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 that 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 requirements 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) show 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 operator is requesting the extension for more than one 

affected source located at the facility, then only one request 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 implement and enforce the emission 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 operator 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 operator'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 specified 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 electroplaters and chromium anodizing operations in 
CM Grinding, Inc. Page 23 of 38

Permit Reviewer: Timothy R. Pettifor 

California which have until January 25, 1998, using the 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 with the emission limitation. The monitoring required to 

demonstrate continuous compliance with the emission limitations is identified in this section for the air 

pollution control techniques expected to be used by the owners or operators 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 agent 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 parameter the surface tension of the bath using Method 

306B, appendix A of this part, setting the maximum value that corresponds to 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 measured by a stalagmometer or 35 

dynes/cm as measured by a tensiometer as the maximum 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 performance test is required to be completed under §63.7, 

except for hard chromium electroplaters and chromium anodizing operations in California, which have 

until January 25, 1998, the owner or operator of an affected 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 tensiometer if the owner or operator is using this value 

in accordance with paragraph (c)(5)(i) of this section, shall constitute noncompliance with the standards. 

The surface tension shall be monitored 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. 

(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 (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 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. 

(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 resumed, with a decrease in monitoring frequency 

allowed following the procedures of paragraphs (c)(5)(ii) (B) and (C) of this section.

§ 63.344 Performance test requirements and test methods. 

(a) Performance test requirements. Performance tests shall be conducted using the test methods and 

procedures in this section and §63.7. Performance test results shall be documented in complete test 

reports that contain the information required by paragraphs (a)(1) through (a)(9) of this section. The test 

plan to be followed shall be made available to the Administrator prior to the testing, if requested. 

(1) A brief process description; 

(2) Sampling location description(s); 

(3) A description of sampling and analytical procedures and any modifications to standard procedures; 

(4) Test results; 

(5) Quality assurance procedures and results; 

(6) Records of operating conditions during the test, preparation of standards, and calibration procedures; 

(7) Raw data sheets for field sampling and field and laboratory analyses; 

(8) Documentation of calculations; and 

(9) Any other information required by the test method. 

(b)(1) If the owner or operator of an affected source conducts performance testing at startup to obtain an 

operating permit in the State in which the affected source is located, the results of such testing may be 

used to demonstrate compliance with this subpart if: 

(i) The test methods and procedures identified in paragraph (c) of this section were used during the 

performance test; 

(ii) The performance test was conducted under representative operating conditions for the source; 

(iii) The performance test report contains the elements required by paragraph (a) of this section; and 

(iv) The owner or operator of the affected source for which the performance test was conducted has 

sufficient data to establish the operating parameter value(s) that correspond to compliance with the 

standards, as required for continuous compliance monitoring under §63.343(c). 

(2) The results of tests conducted prior to December 1991 in which Method 306A, appendix A of this part, 

was used to demonstrate the performance of a control technique are not acceptable. 

(c) Test methods. Each owner or operator subject to the provisions of this subpart and required by 

§63.343(b) to conduct an initial performance test shall use the test methods identified in this section to 

demonstrate compliance with the standards in §63.342. 

(1) Method 306 or Method 306A, “Determination of Chromium Emissions From Decorative and Hard 

Chromium Electroplating and Anodizing Operations,” appendix A of this part shall be used to determine

CM 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 chromium concentration measured by these methods is equal to the 

total chromium concentration for the affected operations. 

(2) The California Air Resources Board (CARB) Method 425 (which is available by contacting the 

California Air Resources Board, 1102 Q Street, Sacramento, 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 sampling 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 limit of the analytical method (i.e., 1.0 microgram per 

liter of sample for AAGF and 0.5 microgram per liter of sample for ICPCR). 

(iii) In the case of either paragraph (c)(2) (i) or (ii) of this 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,” appendix A of this part shall be used to measure the 

surface tension of electroplating and anodizing baths. 

(4) Alternate test methods may also be used if the method has been validated using Method 301, 

appendix A of this part and if approved by the Administrator. Procedures for requesting and obtaining 

approval are contained in §63.7(f). 

(d) Establishing site-specific operating parameter values. (1) Each owner or operator required to establish 

site-specific operating parameters shall follow the procedures in this section. 

(2) All monitoring equipment shall be installed such that representative measurements of emissions or 

process parameters from the affected source are obtained. For monitoring equipment purchased from a 

vendor, verification of the operational status of the monitoring equipment shall include execution of the 

manufacturer's written specifications or recommendations for installation, operation, and calibration of the 

system. 

(3) The surface tension of electroplating and anodizing baths shall be measured using Method 306B, 

“Surface Tension Measurement and Recordkeeping for Tanks used at Decorative Chromium 

Electroplating and Anodizing Facilities,” appendix A of this part. This method should also be followed 

when wetting agent type or combination wetting agent/foam blanket type fume suppressants are used to 

control chromium emissions from a hard chromium electroplating tank and surface tension measurement 

is conducted to demonstrate continuous compliance.

State has been delegated the authority, the owner or operator of an affected source should report 

performance test results to the appropriate authority. 

(2) Reports of performance test results shall be submitted no later than 90 days following the completion 

of the performance test, and shall be submitted as part of the notification of compliance status required by 

paragraph (e) of this section. 

(g) Ongoing compliance status reports for major sources. (1) The owner or operator of an affected source 

that is located at a major source site shall submit a summary report to the Administrator to document the 

ongoing compliance status of the affected source. The report shall contain the information identified in 

paragraph (g)(3) of this section, and shall be submitted semiannually except when: 

(i) The Administrator determines on a case-by-case basis that more frequent reporting is necessary to 

accurately assess the compliance status of the source; or 

(ii) The monitoring data collected by the owner or operator of the affected source in accordance with 

§63.343(c) show that the emission limit has been exceeded, in which case quarterly reports shall be 

submitted. Once an owner or operator of an affected source reports an exceedance, ongoing compliance 

status reports shall be submitted quarterly until a request to reduce reporting frequency under paragraph 

(g)(2) of this section is approved. 

(2) 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 quarterly (or more frequent basis) may reduce 

the frequency of reporting to semiannual if all of the following conditions are met: 
CM Grinding, Inc. Page 30 of 38 

South Bend, Indiana M 141-21370-00190 

Permit Reviewer: Timothy R. Pettifor 

(A) For 1 full year (e.g., 4 quarterly or 12 monthly 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 reduced reporting frequency for the affected source, as 

provided in paragraphs (g)(2) (ii) and (iii) of this section. 

(ii) The frequency of submitting ongoing compliance status 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 information concerning the source's entire 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 evaluations 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 judgment about the source's potential for noncompliance in the future. If the Administrator 

disapproves the owner or operator's request to reduce reporting frequency, the Administrator will notify 

the owner or operator in writing within 45 days after receiving 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 disapproval 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 quarterly, and the owner shall state 

this exceedance in the ongoing compliance status 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 Administrator to reduce the reporting frequency as allowed 

by paragraph (g)(2) of this section. 

(3) Contents of ongoing compliance status reports. The owner or operator of an affected source for which 

compliance monitoring is required in accordance with §63.343(c) shall prepare a summary report to 

document the ongoing compliance status of the source. The report must contain the following information: 

(i) The company name and address of the affected source; 

(ii) An identification of the operating parameter that is monitored for compliance determination, as 

required by §63.343(c); 

(iii) The relevant emission limitation for the affected source, and the operating parameter value, or range 

of values, that correspond to compliance with this emission limitation as specified in the notification of 

compliance status required by paragraph (e) of this section; 

(iv) The beginning and ending dates of the reporting period; 

(v) A description of the type of process performed in the affected source; 

(vi) The total operating time of the affected source during the reporting period; 

(viii) A summary of operating parameter values, including the total duration of excess emissions during 

the reporting period as indicated by those values, the total duration of excess emissions expressed as a 

percent of the total source operating time during that reporting period, and a breakdown of the total 
CM Grinding, Inc. Page 31 of 38

Permit Reviewer: Timothy R. Pettifor 

duration of excess emissions during the reporting period into those that are due to process upsets, control 

equipment malfunctions, other known causes, and unknown causes; 

(ix) A certification by a responsible official, as defined in §63.2, that the work practice standards in 

§63.342(f) were followed in accordance with the operation and maintenance plan for the source; 

(x) If the operation and maintenance plan required by §63.342(f)(3) was not followed, an explanation of 

the reasons for not following the provisions, an assessment of whether any excess emission and/or 

parameter monitoring exceedances are believed to have occurred, and a copy of the report(s) required by 

§63.342(f)(3)(iv) documenting that the operation and maintenance plan was not followed; 

(xi) A description of any changes in monitoring, processes, or controls since the last reporting period; 

(xii) The name, title, and signature of the responsible official who is certifying the accuracy of the report; 

and 

(xiii) The date of the report. 

(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 shall 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 used 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 the 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 source. 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 paragraph (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 indicated 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 source 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 paragraph (h)(3) of this section is approved. 

(iii) The Administrator may determine on a case-by-case basis that the summary 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 retaining 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 reduced 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 status 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 information 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 evaluations 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 reduce reporting frequency, the Administrator will notify 

the owner or operator in writing within 45 days after receiving 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 disapproval 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 status 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 Administrator to reduce the reporting frequency as allowed 

by paragraph (h)(3) of this section.

Permit (MSOP) Renewal 

Source Background and Description 

 Source Name: CM Grinding, Inc. 

 Source Location: 23550 Ardmore Trail, South Bend, IN 46628 

 County: St. Joseph 

 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 Quality (OAQ) had a notice published in the South Bend 

Tribune, 225 West Colfax, South Bend, 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 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. 

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 applicable 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 below the exemption level. 

 Condition A.2 and Section D.1 have been revised to include the third tank as follows:

 2. The HAP and particulate emissions from electroplating operations have been recalculated, and 

 the table now includes the potential emissions from Tank 3. No changes have been made to 

 the TSD because the OAQ prefers that the Technical Support Document reflect the permit that 

 was on public notice. Changes that occur after 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.

3. 40 CFR 63.340, Subpart N, was revised on December 19, 2005. That version of the 40 

CFR 63.340, Subpart N, was not incorporated in the 326 IAC 20 at the time of public 

notice of the draft permit. 40 CFR63.340, Subpart N, version December 19, 2005 has 

now been incorporated into 326 IAC 20-8. Condition D.1.3 has been revised and 

Condition D.1.5 has been deleted.

 (2) If you are the owner or operator of a source subject to the provisions of this subpart, 

 you are also subject to title V permitting requirements under 40 CFR parts 70 or 71, as 

 applicable. Your title V permitting authority may defer your source from these permitting 

 requirements until December 9, 2004, if your source is not a major source and is not 

 located at a major source as defined under 40 CFR 63.2, 70.2, or 71.2, and is not 

 otherwise required to obtain a title V permit. If you receive a deferral under this section, 

 you must submit a title V permit application by December 9, 2005. You must continue to 

 comply with the provisions of this subpart applicable to area sources, even if you receive 

 a deferral from title V permitting requirements.

 D.1.5 One Time Deadlines Relating to the National Emission Standards for Chromium 

Emissions From Hard and Decorative Chromium Electroplating and Chromium Anodizing 

Tanks

 The Permittee must submit an application for a Title V permit by December 9, 2005, if the 

EPA does not exempt this source category from the requirement to have a Title V permit. 

4. 40 CFR 63, Subpart N was also revised on July 19, 2004. That version of the 40 CFR 63, 

Subpart N was not incorporated in the 326 IAC 20 at the time of public notice of the draft 

permit. 40 CFR 63, Subpart N, version July 19, 2004 has also been incorporated into 326 

IAC 20-8. Therefore, Condition D.1.4 has been deleted. 

 D.1.4 State Only National Emission Standards for Chromium Emissions From Hard and 

 Decorative Chromium Electroplating and Chromium Anodizing Tanks Requirements [326 

 IAC 20-8] 

 Pursuant to 326 IAC 20-8, the Permittee shall comply with the provisions of the July 1, 

 2002 version of 40 CFR Part 63, Subpart N, which are incorporated by reference as 326 

 IAC 20-8, for the hard chrome electroplating tanks, identified as Tank 1 and Tank 2. The 

 Permittee shall comply with the provisions of 40 CFR Part 63, Subpart N, as listed in 

 condition D.1.3, except the Permittee shall follow the more stringent requirements of the 

 July 1, 2002 version, as incorporated into 326 IAC 20-8, as specified as follows.

 (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 Sec. 63.342 through the use of a 

 wetting agent in the electroplating or anodizing bath shall determine the outlet chromium 

 concentration using the procedures in Sec. 63.344(c). The owner or operator shall

 establish as the site-specific operating parameter the surface tension of the bath using 

 Method 306B, appendix A of this part, setting the maximum value that corresponds to 
CM Grinding, Inc. Page 6 of 26 

South Bend, Indiana M 141-21370-00190 

Permit Reviewer: Timothy R. Pettifor 

 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, 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 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 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 if the owner or operator is using this value in accordance with 

 paragraph (c)(5)(i) of this section, shall constitute noncompliance with the standards. The 

 surface tension shall be monitored 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.

 (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 (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 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.

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 June 30, 2005, with additional 

information received on July 15, 2005. 

Emission Calculations 

See Appendix A of this document for detailed emission calculations, pages 1 through 3.

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 its physical and operational 

design. Any physical or operational limitation on the capacity of a source to emit an air pollutant, 

inclulding 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.”

Total <0.2 

(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 the twenty-eight (28) listed source categories 

under 326 IAC 2-2 and since there are no applicable New Source Performance Standards 

that were in effect on August 7, 1980, the fugitive emissions are not counted toward 

determination of PSD and Emission Offset applicability.

South Bend, Indiana TSD to 141-21370-00190 

Permit Reviewer: Jed D. Wolkins 

Quality Standards (NAAQS) for ozone. Therefore, VOC and NOx emissions are 

considered when evaluating the rule applicability 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 Applicability – Entire Source section. 

(b) St. Joseph County has been classified as attainment or unclassifiable for PM-10, SO2, 

NO2, Ozone under the one hour standard, CO, and 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 directed states to regulate PM10 emissions as 

surrogate for PM2.5 emissions. See the State Rule Applicability – Entire Source section. 

(d) Fugitive Emissions 

Since this type of operation is not one of the 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. 

Source Status

SO2 <0.1 

VOC <0.1 

CO <0.1 

NOx <0.1

(a) This existing source is not a major stationary 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 from 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 IAC 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, identified as Tank 1 and Tank 2, are subject to the 

National Emission Standards for Hazardous Air Pollutants, 326 IAC 20-8, (40 CFR 63.340, 

Subpart N). 

The hard chrome electroplating tanks, identified 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 Permittee 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 subject 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. 

(1) 40 CFR 63.340 (a).

The provisions of 40 CFR 63 Subpart A – General 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 (Emergency Reduction Plans) 

 The source is not required to submit an Emergency Reduction Plan. 

326 IAC 1-6-3 (Preventive Maintenance Plan) 

(a) If required by specific condition(s) in Section 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) responsible 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 quantification of the replacement parts 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 the 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 subject 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 SO2. 

326 IAC 2-2 (Prevention of Significant Deterioration) 

The total source potential emissions of PM, PM-10, SO2, VOC, NOx, CO, and Lead are less than 

250 tons per year. The source is not one of the 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 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 Emission Offset and is currently considered a minor 

Emission Offset source. Therefore the requirements of 326 IAC 2-3 (Emission Offset) do not 

apply.

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 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 per year. 

The source consists of hard chromium electroplating 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 thirty 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. Therefore, this source is not subject to 326 IAC 6-4. 

The privisous permit incorrectly included the requirement. 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. Therefore, 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 particulate matter per year. 

Therefore, the hard chrome electroplating tanks, identified as Tank 1 and Tank 2, are exempt for 

326 IAC 6.5. 

326 IAC 6-3 (Particulate Emission Limitations for Manufacturing Processes) 
CM Grinding, Inc. Page 9 of 9 

South Bend, Indiana TSD to 141-21370-00190 

Permit Reviewer: Jed D. Wolkins 

The limits in 326 IAC 20-8 for the hard chrome electroplating 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, are 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. Therefore, 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 the 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 applicable 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) allowed 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 Permittee 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 using 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 “sources performing hard chromium electroplating.” 

The change clarifies that sources do not preform tanks. The requirement 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. 

Conclusion 

The operation of this small hard chromium electroplating source shall be subject to the conditions 

of the Minor Source Operating Permit 141-21370-00190.
