### § 63.11511 What definitions apply to this subpart?

Terms used in this subpart are defined in this section.

Batch electrolytic process tank means a tank used for an electrolytic process in which a part or group of parts, typically mounted on racks or placed in barrels, is placed in the tank and immersed in an electrolyticMetal Finishing Co., Inc. Page 14 of 18 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

process solution as a single unit (i.e., as a batch) for a predetermined period of time, during which none of the parts are removed from the tank and no other parts are added to the tank, and after which the part or parts are removed from the tank as a unit.

Bath means the liquid contents of a tank that is used for electroplating, el ectroforming, electropolishing, or other metal coating processes at a plating and polishing facility.

Capture system means the collection of components used to capture gases and fumes released from one or more emissions points and then convey the captured gas stream to a control device, as part of a complete control system. A capture system may include, but is not limited to, the following components as applicable to a given capture system design: duct intake devices , hoods, enclosures, ductwork, dampers, manifolds, plenums, and fans.

Cartridge filter means a type of control device that uses perfo rated metal cartridges containing a pleated paper or non-woven fibrous filter media to remove PM from a gas stream by sieving and other mechanisms. Cartridge filters can be designed with single use cart ridges, which are removed and disposed after reaching capacity, or continuous use cartridges, which typica lly are cleaned by means of a pulse-jet mechanism.

Composite mesh pad means a type of control device similar to a mesh pad mist eliminator except that the device is designed with multiple pads in series that ar e woven with layers of material with varying fiber diameters, which produce a coalescing effect on the droplets or PM that impinge upon the pads.

Continuous electrolytic process tank means a tank that uses an electr olytic process and in which a continuous metal strip or other ty pe of continuous substrate is fed into and removed from the tank continuously. This process is also calle d reel-to-reel electrolytic plating.

Control device means equipment that is part of a control system that collect s and/or reduces the quantity of a pollutant that is emitted to the air. The control device receives emi ssions that are transported from the process by the capture system.

Control system means the combination of a c apture system and a control devic e. The capture system is designed to collect and transport air emissions from t he affected source to the control device. The overall control efficiency of any control system is a combi nation of the ability of the system to capture the air emissions ( i.e. , the capture efficiency) and t he control device efficiency. Cons equently, it is important to achieve good capture to ensure good overall control e fficiency. Capture devices that are known to provide high capture efficiencies include hoods, enclosures, or any other duct intake devices with ductwork, dampers, manifolds, plenums, or fans.

Cyanide plating means plating processes performed in tanks that use cyanide as a major bath ingredient and that operate at pH of 12 or more , and use or emit any of the platin g and polishing metal HAP, as defined in this section. Electroplating and electroforming are performed with or without cyanide. The cyanide in the bath works to dissolve the HAP metal added as a cyanide compound ( e.g. , cadmium cyanide) and creates free cyanide in solution, which helps to corrode the anode. These tanks are self-regulating to a pH of 12 due to the caustic nature of the cyanide bath chemistry. The cyanide in the bath is a major bath constituent and not an additive; however, the self-regulating chemistry of the bath causes the bath to act as if wetting agents/fume suppressants are being used and to ensure an optimum plating process. All cyanide plating baths at pH greater than or equal to 12 have cyanide -metal complexes in solution. The metal HAP to be plated is not emitted because it is either bound in the metal-cyanide complex or reduced at the cathode to elemental metal, and plated onto the immersed parts. Cy anide baths are not intent ionally operated at pH less 12 since unfavorable plating conditions would occur in the tank, among other negative effects.

Deviation means any instance in which an affected source or an owner or operator of such an affected

source:

Operat ion of the affected source at a su rface tension greater than the value established during the performance te st, 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 st andards. The surface tension shall be monitored 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 tensiomete r as specified in Method 306B, appendix A of this part.

(B) The time between monitoring can be increased if there have been no exceedan ces. 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 duri ng 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, su rface tension measurement may be c onducted once every 40 hours of tank operation on an ongoing basis, until an exceedan ce occurs. The minimum frequency of monitoring allowed by this subpart is once ev ery 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 operation. Once an exceedance does not occur for 40 hours of tank operation, monitoring can occur once every 8 hour s 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.Metal Finishing Co., Inc.

(6) Foam blanket-type 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 foam blanket in the electroplating or anodizing bath shall determine the outlet chromium concentration using the procedures in §63.344(c), and shall establish as the site-specific oper ating parameter the thickne ss of the foam blanket, setting the minimum thickness that corre sponds to compliance with the applicable emission limitation. In lieu of establishing the minimum foam bl anket thickness during the performance test, the owner or operator may accept 2.54 centimeters (1 inch) as the minimum f oam blanket thickness that corresponds to compliance with the applicable emission limitation. All foam blan ket 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 performa nce 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 operat or of an affected source shall moni tor the foam blanket thickness of the electroplating or anodizing bath. Operation of the affected source at a foam blanket thickness less than the value established during the performance test, or le ss 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 noncompliance 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 there have been no exceedances. The foam blanket thickness shall be measured once every hour of tank operation for the first 40 hour s of tank operation after the compliance date. Once there are no exceedances fo r 40 hours of tank operation, foam blanket thickness measurement may be conducted once every 4 hours of tank operation. Once there are no exceedances during 40 hours of tank operation, f oam blanket thickness measurement may be conducted once every 8 hours of tank operation on an ongoing basis, until an exceedance occurs. The minimum frequency of monitoring 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 resum ed. A subsequent decrease in frequency shall follow the schedule laid out in paragraph (c)(6)(ii)(B) of this se ction. For example, if an owner or operator had been monitoring an affected source once every 8 hours and an exceedance occurs, subsequent monitoring 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, monitori ng 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 monitoring frequency allowed following the procedures of paragraphs (c)(6)( ii) (B) and (C) of this section.

(7) Fume suppressant/add-on control device. (i) If the owner or operator of an affected source uses both a fume suppressant and add-on control device and both ar e needed to comply with the applicable emission limit, monitoring requirements as identified in paragrap hs (c) (1) through (6) of this section, and the work practice standards of Table 1 of §63.342, apply for each of the control techniques used.

(ii) If the owner or operator of an affected source us es both a fume suppressant and add-on control device, but only one of these techniques is needed to comply with the applicable emission limit, monitoring requirements as identified in paragraphs (c) (1) throug h (6) of this section, and work practice standards of Table 1 of §63.342, apply only for the contro l technique used to achieve compliance.

(8) Use of an alternative monitoring method. (i) Requests and approvals of alternative monitoring methods shall be considered in accordance with §6 3.8(f)(1), (f)(3), (f)(4), and (f)(5).

(ii) After receipt and consideration of an application fo r an alternative monitoring method, the Administrator may approve alternatives to any monitoring methods or procedures of this subpart including, but not limited to, the following:Metal Finishing Co., Inc.

(A) Alternative monitoring requirements when installati on or use of monitoring devices specified in this subpart would not provide accurate measurements due to interferences caused by substances within the effluent gases; or

(B) Alternative locations for installing monitoring devi ces when the owner or operator can demonstrate that installation at alternate locations will enab le accurate and representative measurements.

(d) An owner or operator who uses an air pollution cont rol device not listed in this section shall submit a description of the device, test results collected in a ccordance with §63.344(c) verifying the performance of the device for reducing chromium emissions to the atmo sphere to the level required by this subpart, a copy of the operation and maintenance plan referenced in §63.342(f) including operation and maintenance practices, and appropriate operating parameters that will be monitored to establish continuous compliance with the standards. The monitoring plan submitted identifying the continuous compliance monitoring is subject to the Administrator's approval.

(a) Performance test requirements. Performance tests shall be conduc ted 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 Administ rator prior to the testing, if requested.

(1) A brief process description;

(2) Sampling location description(s);

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

(4) Test results;

(5) Quality assurance procedures and results;

(6) Records of operating conditions during the tes t, 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 repr esentative operating conditions for the source;

(iii) The performance test report contains the elem ents required by paragraph (a) of this section; andMetal Finishing Co., Inc. Page 17 of 38 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

(iv) The owner or operator of the affected source for which the performance test was conducted has sufficient data to establish the oper ating parameter value(s) that co rrespond to compliance with the standards, as required for continuous compliance monitoring under §63.343(c).

(2) The results of tests conducted prior to December 19 91 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 pr ovisions 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,” appendi x A of this part shall be used to determine the chromium concentration from hard or decorative ch romium electroplating tanks or chromium anodizing tanks. The sampling time and sample volume for each run of Methods 306 and 306A, appendix 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 chro mium 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 chro mium electroplating tanks and chromium anodizing tanks if the following conditions are met:

(i) If a colorimetric analysis method is used, the samplin g 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,” appe ndix A of this part shall be used to measure the surface tension of electr oplating and anodizing baths.

(i) Specifications for differential pressure measurement devices used to measure velocity pressure shall be in accordance with section 2.2 of Method 2 (40 CFR part 60, appendix A).Metal Finishing Co., Inc. Page 18 of 38 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

(ii) Specification for differential pressure measur ement devices used to measure pressure drop across a control system shall be in accordance with manufacturer's accuracy specifications.

(3) The surface tension of electroplating and ano dizing 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.

(4) The owner or operator of a source required to measur e the velocity pressure at the inlet to an add-on air pollution control device in accordance with §63.343(c)(2 ), shall establish the site-specific velocity pressure as follows:

(i) Locate a velocity traverse port in a section of stra ight duct that connects the ho oding on the plating tank or tanks with the control device. The port shall be loca ted as close to the control system as possible, and shall be placed a minimum of 2 duct diameters down stream and 0.5 diameter upstream of any flow disturbance such as a bend, expans ion, or contraction (see Method 1, 40 CFR part 60, appendix A). If 2.5 diameters of straight duct work does not exist, locate the port 0.8 of the duct di ameter downstream and 0.2 of the duct diameter upstream from any flow disturbance.

(ii) A 12-point velocity traverse of the duct to t he control device shall be conducted along a single axis according to Method 2 (40 CFR part 60, appendix A) using an S-type pitot t ube; measurement of the barometric pressure and duct temperatur e at each traverse point is not re quired, but is suggested. Mark the S-type pitot tube as specified in Method 1 (40 CFR par t 60, appendix A) with 12 points. Measure the velocity pressure ( ∆ p) values for the velocity poin ts and record. Determine the square root of the individual velocity point ∆ p values and average. The point with the square root value that comes closest to the average square root value is the point of average velocity. The ∆ p value measured for this point during the performance test will be used as the reference for future monitoring.

(5) The owner or operator of a source required to measure the pressure drop across the add-on air pollution control device in accordance with §63.343(c) (1) thr ough (4) may establish the pressure drop in accordance with the following guidelines:

(i) Pressure taps shall be installed at any of the following locations:

(A) At the inlet and outlet of the cont rol system. The inlet tap should be installed in the ductwork just prior to the control device and the corresponding outlet pressu re tap should be installed on the outlet side of the control device prior to the blower or on the downstream side of the blower;

(B) On each side of the packed bed within the control system or on each side of each mesh pad within the control system; or

(C) On the front side of the first mesh pad and back side of the last mesh pad within the control system.

(ii) Pressure taps shall be sited at locations that are:

(A) Free from pluggage as possible and away from any flow disturbances such as cyclonic demisters.

(B) Situated such that no air infiltra tion at measurement site will occur that could bias the measurement.

(iii) Pressure taps shall be constructed of either polye thylene, polybutylene, or ot her nonreactive materials.

(iv) Nonreactive plastic tubing shall be used to conn ect the pressure taps to the device used to measure pressure drop.Metal Finishing Co., Inc. Page 19 of 38 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

(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.

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

(e) Special compliance provisions for multiple sources controlled by a common add-on air pollution control device. (1) This section identifies procedures for meas uring the outlet chromium concentration from an addon 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 sa me type 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 c ontrolling emissions from any other type of affected operation or from any nonaffected sources, the applicable emi ssion 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 type of operation and subject to the same emission limitation are controlled with a common add-on air pollution control device that is also controlling emissions from sources not affected by these standards, the fo llowing procedures should be followed to determine compliance with the applicable emission limitation in §63.342:

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

(ii) Determine the total sample time per test run by di viding the total inlet area from all tanks connected to the control system by the total inlet area for all ducts a ssociated with affected sources, and then multiply this number by 2 hours. The calculated time is t he 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 inlet 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.Metal Finishing Co., Inc. Page 20 of 38 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

(4) When multiple affected sources performing di fferent types of operations (e.g., hard chromium electroplating, decorative chromium electroplating, or chromium anodizing) are controlled by a common addon air pollution control device that may or may not al so be controlling emissions from sources not affected by these standards, or if the affected sources cont rolled by the common add-on air pollution 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:

(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 for all ducts conveying chromic acid from each type of affe cted 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 a ffected 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 add-on air pollution control device using equation 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 for all hard chromium electroplating tanks subject to the same emission limitation, “dc” ap plies to the total of ventilation rates for the decorative chromium electroplating tanks, “ca” ap plies to the total of ventilation 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 elec troplating tanks because different emission 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 equat ion 8 should be equal to or more than the outlet three-run average mass emission rate determined from Me thod 306 testing in order for the source to be in compliance with the standards.

(5) Each owner or operator that uses the special co mpliance provisions of this paragraph to demonstrate compliance with the emission limitatio ns of §63.342 shall submit the measurements and calculations to support these compliance methods with the notificat ion of compliance status required by §63.347(e).Metal Finishing Co., Inc. Page 21 of 38 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

(6) Each owner or operator that uses the special co mpliance provisions of this section to demonstrate compliance with the emission limitatio ns of §63.342 shall repeat these procedures if a tank is added or removed from the control system regardless of whet her 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 control system through the same size inlet duct then this procedure does not have to be repeated.

(f) Compliance provisions for the mass rate emission st andard for enclosed hard chromium electroplating tanks. (1) This section identifies procedures for calcul ating the maximum allowable mass emission rate for owners or operators of affected sources who choos e 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 electroplating tank that is an affected source other than an existing affected source located at a sm all 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 atmosphere 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 li mit 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 chromi um electroplating 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 atmosphe re to exceed the maximum allowable mass emission rate calculated using equation 10:

MAMER = ETSA × K × 0.03 mg/dscm. (10)

(B) Compliance with the alternative mass emission li mit 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.

Page 27 of 38 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

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:

(A) For 1 full year (e.g., 4 quarterly or 12 monthly repo rting 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 re porting frequency for the affected source, as provided in paragraphs (g)(2) (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 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 evaluat ions 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 rece iving notice of the owner or operator's intention. The notification from the Administrator to the owner or op erator will specify the groun ds 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 §63.3 43(c) show that the source is not in compliance with the relevant emission limit, the frequency of reporting shal l revert to quarterly, and the owner shall state this exceedance in the ongoing compliance status report for the next reporting per iod. After demonstrating ongoing compliance with the relevant emission limit fo r 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 stat us 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 operati ng 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 emi ssion limitation as specifi ed 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 pr ocess performed in the affected source;

(vi) The total operating time of the affe cted source during the reporting period;Metal Finishing Co., Inc. Page 28 of 38 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

(vii) If the affected source is a hard chromium electropla ting tank and the owner or operator is limiting the maximum cumulative rectifier capacity in accordance wi th §63.342(c)(2), the actual cumulative rectifier capacity expended during the reporting period, on a month-by-month basis;

(viii) A summary of operating parameter values, includ ing the total duration of excess emissions during the reporting period as indicated by those values, the tota l duration of excess emissions expressed as a percent of the total source operating time during that reporting period, and a br eakdown of the total 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 practi ce 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 §6 3.342(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 operat ion 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; 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 o perator shall report the results as required for each monitoring device. However, when one monitoring device is used as a backu p for the primary monitoring device, the owner or operator shall only report the results fr om the monitoring device used to m eet the monitoring requirements of this subpart. If both devices are used to meet these r equirements, then the owner or operator shall report the results 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 requir ements 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 stat us 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:

(B) The total duration of malfunction s 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 shal l be submitted semiannually until a request to reduce reporting frequency under paragraph (h)(3) of this section is approved.Metal Finishing Co., Inc. Page 29 of 38 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram

(iii) The Administrator may determine on a case-by-case basis that the summary report shall be completed more frequently and submitted, or t hat 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.

(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 quarterl y 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 re porting 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 information concerning the source's previous performance history during the 5-year recordkeeping period prior to the in tended change, or the recordkeeping period since the source's compliance date, whichever is shorter. Re cords 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 noncom pliance in the future. If the Administrator disapproves the owner or operator's request to reduce reporting frequency, the Admi nistrator 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 §63.3 43(c) show that the source is not in compliance with the relevant emission limit, the frequency of reporting sh all revert to semiannual, and the owner shall state this exceedance in the ongoing compliance status r eport for the next reporting period. After demonstrating ongoing compliance with the relevant emission limit fo r 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 paragraph do not alleviate affected sources from complying with the requirements of State or Federal oper ating permit programs under title V. Owners or operators complying with the provis ions of §63.342(e) are not subject to paragraphs (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:

Page 3 of 8 Indianapolis, Indiana M097-25773-00396 Permit Reviewer: Jillian Bertram


### (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 Counties 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-designate Boone, Clark, Elkhart, Floyd, LaPorte, Hamilton, Hancock, Hendricks, Johnson, Madison, Marion, Morgan, Shelby, and St. Joseph Counties 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. Marion 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

Marion County has been classified as nonattainment for PM2.5 in 70 FR 943 dated January 5, 2005. On May 8 th 

### , 2008, U.S. EPA promulgated specific New Source Review rules for PM2.5 emissions, and the effe ctive date of these rules was July 15 th 

### , 2008. Therefore, direct PM2.5 and SO2 emissions were reviewed pursuant to the requirements of Nonattainment New Source Review, 326 IAC 2-1.1-5. See the State Rule Applicability – Entire Source section.

(c) Other Criteria Pollutants

Marion County has been classified as attainment or unclassifiable in Indiana for all other criteria pollutants. Therefore, these emissions we re reviewed pursuant to the requirements for Prevention of Significant Deterioration (PSD), 326 IAC 2-2.

(d) Fugitive Emissions

Since this type of operation is not one of t he 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.

Unrestricted Potential Emissions

Appendix A of this TSD reflects the unrest ricted potential emissions of the source.

(a) Even though the PTE of each pollutant is le ss than 25 tons/yr, the existing source is subject to 326 IAC 20-8, but not subject to 326 IAC 2-5.5-1(b)(2)(Registration) because the source uses hexavalent chromium for dec orative coating as opposed to trivalent chromium, and the potential to emit (as defi ned in 326 IAC 2-7-1(29)) of all criteria pollutants is less than 100 tons per year. T he source is subject to the provisions of 326 IAC 2-6.1. Therefore, the source will be issued an MSOP Renewal.

(b) The potential to emit (as defined in 326 IAC 2- 7-1(29)) of any single HAP is less than ten (10) tons per year and/or 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.

(c) Since this type of operation is not one of the twenty-eight (28) listed source categories under 326 IAC 2-7, fugitive emissions are not counted toward the determination of Part 70 applicability.
