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 ther e have been no exceedances. The surface tension shall be measured once every 4 hours of tank operation for the fi rst 40 hours of tank operation after the compliance date. Once there are no exceedances during 40 hours of tank op eration, surface tension m easurement 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 conducte d once every 40 hours of tank operat ion on an ongoing basis, until an exceedance occurs. The minimum frequency of monitoring a llowed by this subpart is once every 40 hours of tank operation.

(C) Once an exceedance occurs as indicated through surfac e 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 inMcDowell Enterprises, Inc. Page 39 of 104 Elkhart, Indiana M039-26362-00413 Permit Reviewer: Christina Lowry

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.

In lieu of establishing the minimum foam blanket thickness during the performance test, the owner or operator may accept 2.54 ce ntimeters (1 inch) as the minimum foam blanket thickness that corresponds to compliance with the app licable emission limitation. All foam blanket measurements must be taken in close proximity to the workpiece or cathode area in the plating tank(s).

(ii) On and after the date on which the initial performance te st is required to be completed under §63.7, except for hard chromium electroplaters and chromium anodizing operati ons in California which have until January 25, 1998, the owner or operator of an affected source shall monitor the foam blanket thickness of the electroplating or anodizing bath. Operation of the affe cted source at a foam blanket thickne ss less than the value established during the performance test, or less than 2.54 cm (1 inch) if the owner or operator is using this value in accordance with paragraph (c)(6)(i) of this section, shall constitute nonc ompliance with the standards. The foam blanket thickness shall be measured according to the following schedule:

(A) The foam blanket thickness shall be me asured once every 1 hour of tank operation.

(B) The time between monitoring can be increased if ther e have been no exceedances. The foam blanket thickness shall be measured once every hour of t ank operation for the first 40 hours of tank operation after the compliance date. Once there are no exceedances for 40 hours of tank operation, foam blanket thickness measurement may be conducted once every 4 hours of tank operation. Once there are no exceedanc es during 40 hours of tank operation, foam blanket thickness measurement may be conducted on ce every 8 hours of tank operation on an ongoing basis, until an exceedance occurs. The minimum frequency of monitori ng allowed by this subpart is once per 8 hours of tank operation.

(C) Once an exceedance occurs as indicated through foam blanket thickness monitoring, the original monitoring schedule of once every hour must be resumed. A subsequent decrease in frequency shall follow the schedule laid out in paragraph (c)(6)(ii)(B) of this section. For example, if an owner or operator had been monitoring an affected source once every 8 hours and an exceedance occurs, subsequent m onitoring would take place once every hour of tank operation. Once an exceedance does not occur for 40 hours of tank operation, monitoring can occur once every 4 hours of tank operation. Once an exceedance does not occur for 40 hours of tank operation on this schedule, monitoring can occur once every 8 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 hour must be resumed, with a decrease in m onitoring frequency allowed following the procedures of paragraphs (c)(6)(ii) (B) and (C) of this section.

(v) Any of the following pressure gauges can be used to monitor pressure drop: a magnehelic gauge, an inclined manometer, or a “U” tube manometer.McDowell Enterprises, Inc. Page 43 of 104 Elkhart, Indiana M039-26362-00413 Permit Reviewer: Christina Lowry

(vi) Prior to connecting any pressure lines to the pre ssure gauge(s), each gauge should be zeroed. No calibration of the pressure gauges is required.

(e) Special compliance provisions for multiple sources cont rolled by a common add-on air pollution control device. (1) This section identifies procedures for measuring the outl et chromium concentration from an add-on air pollution control device that is used to control multiple sources that may or may not include sources not affected by this subpart.

(2) When multiple affected sources performing the same ty pe of operation (e.g., all are performing hard chromium electroplating), and subject to the same emission limitation, are controlled with an add-on air pollution control device that is not controlling emissions from any other type of affected operation or from any nonaffected sources, the applicable emission limitation identified in §63.342 must be met at the outlet of the add-on air pollution control device.

(3) When multiple affected sources performing the same ty pe of operation and subject to the same emission limitation are controlled with a common add-on air pollution control devi ce that is also controlling emissions from sources not affected by these standards, the following procedures should be followed to determine compliance with the applicable emission limitation in §63.342:

(i) Calculate the cross-sectional area of each inlet duct (i.e ., uptakes from each hood) including those not affected by the standard.

(ii) Determine the total sample time per test run by dividi ng the total inlet area from all tanks connected to the control system by the total inlet area for all ducts associated with affected sources, and then multiply this number by 2 hours. The calculated time is the minimum sample time required per test run.

(iii) Perform Method 306 testing and calculate an outlet mass emission rate.

(iv) Determine the total ventil ation rate from the affected sources by using equation 1:



### where VR tot 

### is the average total ventilation rate in dscm/min for the three test runs as determined at the outlet by means of the Method 306 testing; IDA i 

### is the total inlet area for all ducts associated with affected sources; IA total 

### is the sum of all inlet duct areas from both affected and nonaffected sources; and VR inlet 

### is the total ventilation rate from all inle t ducts associated with affected sources.

(v) Establish the allowable mass emission rate of the system (AMR sys ) in milligrams of total chromium per hour (mg/hr) using equation 2:



### where Σ VR inlet 

### is the total ventilation rate in dscm/min from the affected sources, and EL is the applicable emission limitation from §63.342 in mg/dscm. The allowable mass emission rate (AMR sys 

### ) calculated from equation 2 should be equal to or more than the outlet three-run average mass emission rate determined from Method 306 testing in order for the source to be in compliance with the standard.

(4) When multiple affected sources performing different types of operations (e.g., hard chromium electroplating, decorative chromium electroplating, or chromium anodizi ng) are controlled by a common add-on air pollution control device that may or may not also be controlling emissions from sources not affected by these standards, or if the affected sources controlled by the common add-on air polluti on control device perform the same operation but are subject to different emission limitations (e.g., because one is a new hard chromium plating tank and one is an existing small, hard chromium plating tank), the following procedures should be followed to determine compliance with the applicable emission limitation in §63.342:McDowell Enterprises, Inc. Page 44 of 104 Elkhart, Indiana M039-26362-00413 Permit Reviewer: Christina Lowry

(i) Follow the steps outlined in paragraphs (e)( 3)(i) through (e)(3)(iii ) of this section.

(ii) Determine the total ventilati on rate for each type of affected source using equation 3:



### where VR tot 

### is the average total ventilation rate in dscm/min for the three test runs as determined at the outlet by means of the Method 306 testing; IDA i,a 

### is the total inlet duct area fo r all ducts conveying chromic acid from each type of affected source performing the same operation, or each type of affected source subject to the same emission limitation; IA total 

### is the sum of all duct areas from both affected and nonaffected sources; and VR inlet,a 

### is the total ventilation rate from all inlet ducts conveying chromic acid from each type of affected source performing the same operation, or each type of affected source subject to the same emission limitation.

(iii) Establish the allowable mass emission rate in mg/hr for each type of affected source that is controlled by the addon air pollution control device using eq uation 4, 5, 6, or 7 as appropriate:

VR hc1 × EL hc1 × 60 minutes/hour = AMR hc1 (4)

VR hc2 × EL hc2 × 60 minutes/hour = AMR hc2 (5)

VR dc × EL dc × 60 minutes/hour = AMR dc (6)

VR ca × EL ca × 60 minutes/hour = AMR ca (7)



### where “hc” applies to the total of ventilation rates fo r all hard chromium electroplating tanks subject to the same emission limitation, “dc” applies to the tota l of ventilation rates for the decorative chromium electroplating tanks, “ca” applies to the total of v entilation rates for the chromium anodizing tanks, and EL is the applicable emission limitation from §63.342 in mg/dscm. There are two equations for hard chromium electroplating tanks because different emis sion limitations may apply (e.g., a new tank versus an existing, small tank).

(iv) Establish the allowable mass emission rate (AMR) in mg/hr for the system using equation 8, including each type of affected source as appropriate:

AMR hc1 + AMR hc2 + AMR dc + AMR ca = AMR sys (8)

The allowable mass emission rate calculated from equation 8 should be equal to or more than the outlet three-run average mass emission rate determined from Method 306 testi ng in order for the source to be in compliance with the standards.

(5) Each owner or operator that uses the special compli ance provisions of this paragraph to demonstrate compliance with the emission limitations of §63.342 shall submit the measurements and calc ulations to support these compliance methods with the notificat ion of compliance status required by §63.347(e).

(6) Each owner or operator that uses the special complianc e provisions of this section to demonstrate compliance with the emission limitations of §63.342 s hall repeat these procedures if a tank is added or removed from the control system regardless of whether that tank is a nonaffected source. If the new nonaffected tank replaces an existing nonaffected tank of the same size and is connected to the c ontrol system through the same size inlet duct then this procedure does not have to be repeated.McDowell Enterprises, Inc. Page 45 of 104 Elkhart, Indiana M039-26362-00413 Permit Reviewer: Christina Lowry

(f) Compliance provisions for the mass rate emission standa rd for enclosed hard chromium electroplating tanks. (1) This section identifies procedures for calculating the maxi mum allowable mass emission rate for owners or operators of affected sources who choose to meet the mass emission rate standard in §63.342(c)(2)(iv) or (v).

(i)(A) The owner or operator of an enclosed hard chromium el ectroplating tank that is an affected source other than an existing affected source located at a small hard chromium electroplating facility who chooses to meet the mass emission rate standard in §63.342(c)(2)(iv) shall determine compliance by not allowing the mass rate of total chromium in the exhaust gas stream discharged to the at mosphere to exceed the maximum allowable mass emission rate calculated using equation 9:

MAMER = ETSA × K × 0.015 mg/dscm (9)



### Where:

MAMER = the alternative emission rate for enclose d hard chromium electroplating tanks in mg/hr.

ETSA = the hard chromium electroplating tank surface area in square feet(ft 2 

### ).

K = a conversion factor, 425 dscm/(ft 2 

### × hr).

(B) Compliance with the alternative mass emission limit is demonstrated if the three-run average mass emission rate determined from Method 306 testing is less than or equal to the maximum allowable mass emission rate calculated from equation 9.

(ii)(A) The owner or operator of an enclosed hard chromium el ectroplating tank that is an existing affected source located at a small hard chromium electroplating facility who chooses to meet the mass emission rate standard in §63.342(c)(2)(v) shall determine compliance by not allowing the mass rate of total chromium in the exhaust gas stream discharged to the atmosphere to exceed the ma ximum allowable mass emission rate calculated using equation 10:

MAMER = ETSA × K × 0.03 mg/dscm. (10)

(B) Compliance with the alternative mass emission limit is demonstrated if the three-run average mass emission rate determined from testing using Method 306 of appendix A to part 63 is less than or equal to the maximum allowable mass emission rate calculated from equation 10.

(C) The Administrator does not object to a reduced repo rting 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 ap prove a reduced reporting frequency, the Administrator mayMcDowell Enterprises, Inc. Page 51 of 104 Elkhart, Indiana M039-26362-00413 Permit Reviewer: Christina Lowry

review information concerning the source's entire previous performance history during the 5-year recordkeeping period prior to the intended change, or the recordkeeping pe riod since the source's compliance date, whichever is shorter. Records subject to review may include perform ance test results, monitoring data, and evaluations of an owner or operator's conformance with emission limitati ons and work practice standards. Such information may be used by the Administrator to make a judgment about the s ource'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 re ceiving notice of the owner or operator's intention. The notification from the Administrator to the owner or oper ator will specify the grounds on which the disapproval is based. In the absence of a notice of disapproval wi thin 45 days, approval is automatically granted.

(iii) As soon as the monitoring data required by §63.343(c) sh ow 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) sh all prepare a summary report to document the ongoing compliance status of the source. The repor t 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 co mpliance determination, as required by §63.343(c);

(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 §63.3 42(f)(3) was not followed, an explanation of the reasons for not following the provisions, an assessment of wh ether 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, proces ses, or controls since t he last reporting period;

(xii) The name, title, and signature of the responsible offi cial who is certifying the accuracy of the report; andMcDowell Enterprises, Inc. Page 52 of 104 Elkhart, Indiana M039-26362-00413 Permit Reviewer: Christina Lowry

(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 monito ring device, the owner or o perator 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 ow ner or operator shall report the result s from each monitoring device for the relevant compliance period.

(h) Ongoing compliance status r eports for area sources. The requirements of this paragraph do not alleviate affected area sources from complying with the requirements of St ate or Federal operating permit programs under 40 CFR part 71.

(1) The owner or operator of an affected source that is loca ted at an area source site shall prepare a summary report to document the ongoing compliance status of the affected source. The report s hall contain the info rmation 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 ann ually 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 repor ts an exceedance as defined in paragraph (h)(2)(i) of this section, ongoing compliance status r eports 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 bas is that the summary report shall be completed more frequently and submitted, or that t he annual report shall be submitted inste ad of being retained on site, if these measures are necessary to accurately asse ss the compliance status of the source.

(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 t he 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 r eporting 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 repo rting 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 ap prove a reduced reporting frequency, the Administrator may review information concerning the source's previous perfo rmance history during the 5-year recordkeeping period prior to the intended change, or the recordkeeping period sinc e the source's compliance date, whichever is shorter. Records subject to review may include performance test re sults, monitoring data, and evaluations of an owner orMcDowell Enterprises, Inc.

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 poten tial for noncompliance in th e future. If the Administrator disapproves the owner or operator's request to reduce repor ting frequency, the Administrator will notify the owner or operator in writing within 45 days after receiving notice of the owner or operator's intent ion. The notification from the Administrator to the owner or operator will specify the gr ounds 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) sh ow 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.

(i) Reports associated with trivalent chromium baths. The requirements of this par agraph do not alleviate affected sources from complying with the requirements of State or Federal operating permit programs under title V. Owners or operators complying with the provisions of §63.342(e) are not subject to paragr aphs (a) through (h) of this section, but must instead submit the following reports:

(1) Within 180 days after January 25, 1995, submit an initial notific ation that includes:

(i) The same information as is required by paragra phs (c)(1) (i) through (v) of this section; and

Remote reservoir continuous web cleaning machine means a continuous web cleaning machine in which there is no exposed solvent sump. In these units, the solvent is pumpe d from an enclosed chamber and is typically applied to the continuous web part through a nozzle or series of nozzles. The solvent then drains from the part and is collected and recycled through the machine, allowing no solvent to pool in the work or cleaning area.

Soils means contaminants that are removed from the parts be ing cleaned. Soils include, but are not limited to, grease, oils, waxes, metal chips, carbon deposits, fluxes, and tars.McDowell Enterprises, Inc. Page 66 of 104 Elkhart, Indiana M039-26362-00413 Permit Reviewer: Christina Lowry

These plia ble surfaces, called squeegees, are typica lly made of rubber or plastic media, and need to be periodically replaced to ensure continued proper function.

Sump means the part of a solvent cleaning machi ne where the liquid solvent is located.

Sump heater coils means the heating system on a cleaning machine that uses steam, electricity, or hot water to heat or boil the liquid solvent.

Superheated part technology means a system that is part of the contin uous web process that heats the continuous web part either directly or indirectly to a temperatur e above the boiling point of the cleaning solvent. This could include a process step, such as a too ling die that heats the part as it is processed, as long as the part remains superheated through the cleaning machine.

Superheated vapor system means a system that heats t he solvent vapor, either passively or actively, to a temperature above the solvent's boiling point. Parts are hel d in the superheated vapor before exiting the machine to evaporate the liquid solvent on them. Hot vapor recy cle is an example of a superheated vapor system.

Vapor cleaning machine means a batch or in-line solvent cleaning mach ine that boils liquid solvent generating solvent vapor that is used as a part of the cleaning or drying cycle.

The 1-hour standard was revoked effective June 15, 2005. Unclassifiable or attainment effective April 5, 2005, for PM2.5.

(a) Ozone Standards

(1) On October 25, 2006, the Indiana Air Pollution Control Board finalized a rule revision to 326 IAC 1-4-1 revoking the one-hour ozone standard in Indiana.

(2) On September 6, 2007, the Indiana Air Pollution Control Board finalized a temporary emergency rule to re-designate Allen, Clark, Elkhart, Floyd, LaPorte, and St. Joseph as attainment for the 8-hour ozone standard.

(3) On November 9, 2007, the Indiana Air Pollution Control Board finalized a temporary emergency rule to re-designat e Boone, Clark, Elkhart, Floyd, LaPorte, Hamilton, Hancock, Hendricks, Johnson, Madison, Marion, Morgan, Shelby, and St. Joseph as attainment for the 8-hour ozone standard.

(4) Volatile organic compounds (VOC) and Nitrogen Oxides (NOx) are regulated under the Clean Air Act (CAA) for the purposes of attaining and maintaining the National Ambient Air Quality Standards (NAAQS) for ozone. Therefore, VOC and NOx emissions are considered when evaluating the rule applicability relating to ozone. Elkhart County has been designated as attainment or unclassifiable for ozone. Therefore, VOC and NOx emissions were reviewed pursuant to the requirements for Prevention of Significant Deterioration (PSD), 326 IAC 2-2.

(b) PM2.5

Elkhart County has been classified as attainment for PM2.5. On May 8, 2008 U.S. EPA promulgated the requirements for Prevention of Significant Deterioration (PSD) for PM2.5 emissions, and the effective date of these rules was July 15 th 

### , 2008. Indiana has three years from the publication of these rules to revise its PSD rules, 326 IAC 2-2, to include those requirements. The May 8, 2008 rule revisions require IDEM to regulate PM10 emissions as a surrogate for PM2.5 emissions until 326 IAC 2-2 is revised.

(c) Other Criteria Pollutants

Elkhart County has been classified as attainm ent or unclassifiable in Indiana for sulfur dioxide (SO2), carbon monoxide (CO), PM 10, nitrogen dioxide (NO2) and lead (Pb). Therefore, these emissions were reviewed pur suant to the requirements of Prevention of Significant Deterioration (PSD), 326 IAC 2-2.

(d) Fugitive Emissions

Since this type of operation is not one of the twenty-eight (28) listed source categories under 326 IAC 2-2 or 326 IAC 2-3, fugitive emissions are not counted toward the determination of PSD and Emission Offset applicability.

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 limitati on on the capacity of a source to emit an air pollutant, including air pollution control equipment and restrictions on hours of operation or type or amount of material combusted, stored, or processed shall be treated as part of its design if the limitation is enforceable by the U. S. EPA, the department, or the appropriate local air pollution control agency.”

State Rule Applicability - Entire Source

(a) 326 IAC 2-2 - Prevention of Significant Deterioration

Construction of this source commenced prior to August 7, 1977; therefore, it was not subject to the PSD requirements of 326 IAC 2-2. The unrestricted potential to emit each criteria pollutant from this source is less than 250 tons per year and this source is not in one of the twenty-eight (28) listed source categories. Therefore, the requirements of 326 IAC 2-2 are still not applicable.

(b) 326 IAC 2-4.1-1 - New Source Toxics Control

The potential to emit each individual hazardous air pollutant (HAP) is less than ten (10) tons per year and the potential to emit any combination of HAPs is less than twenty-five (25) tons per year from the total of all facilities at this source. 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.

(c) 326 IAC 2-6 - Emission Reporting

This source is located in Elkhart County and the potential to emit VOC and NO X 

### is less than ten (10) tons per year and the potential to emit SO 2 

### , CO and PM 10 

### is less than one hundred (100) tons per year. Therefore, 326 IAC 2-6 does not apply.
