Compliance Determination Requirements [326 IAC 2-1.1-11]

D.1.7 Performance Testing [326 IAC 2-1.1-11] [326 IAC 20-8-1] [40 CFR 63.343(b)(2)] [40 CFR 63.7] [40 CFR

63.344]

(a) A performance test demonstrating initial compliance for Tank 1 and Tank 2 was performed

between May 27 and 29, 1997.

During the initial performance test, it was determined that the surface tension of the baths,

using Method 306B, Appendix A of 40 CFR 63, was 49.9 dynes per centimeter at Tank 1 and

48.4 dynes per centimeter at Tank 2. The average total chromium concentrations were 0.0087

mg/dscm at Tank 1 and 0.0100 mg/dscm at Tank 2. 

(b) The Permittee is not required to further test Tank 1 and Tank 2 by this permit. However, the

IDEM may require testing when necessary to determine if the tanks are in compliance. If

testing is required by the IDEM, compliance with the limits specified in Condition D.1.3 shall

be determined by a performance test conducted in accordance with 40 CFR 63.344 and

Section C - Performance Testing. 

(c) Any change, modification, or reconstruction of the tanks, identified as Tank 1 and Tank 2, the

fume suppressant or monitoring equipment may require additional performance testing

conducted in accordance with 40 CFR 63.344 and Section C - Performance Testing.

Compliance Monitoring Requirements [326 IAC 2-6.1-5(a)(2)]

D.1.8 Monitoring to Demonstrate Continuous Compliance [326 IAC 2-6.1-5(a)(2)] [326 IAC 20-8-1] [40 CFR

63.343(c)]

(a) Pursuant to 40 CFR 63.343(c)(5)(ii) and (iii), when using a fume suppressant containing a

wetting agent in the electroplating bath to comply with the limits specified in Condition D.1.3,

the Permittee shall monitor the surface tension and the temperature of the electroplating

baths. Operation of Tank 1 and Tank 2 at a surface tension greater than the value established

during a performance test shall constitute noncompliance with the standards. The temperature

shall not exceed 130 degrees Fahrenheit.

(1) The Permittee shall monitor the surface tension and temperature of the electroplating

bath during tank operation 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 each day of tank

operation provided there are no more than 40 hours between consecutive

measurements. The minimum frequency of monitoring allowed by this

subpart is once every 40 hours of tank operation.
CM Grinding, Inc. Page 18 of 27

South Bend, Indiana MSOP 141-11700-00190

Permit Reviewer: CAO/MES

(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 (B) above. For example, if a Permittee had been monitoring a tank

once each day 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 each day

of tank operation provided there are no more than 40 hours between

consecutive measurements.

(2) Once a bath solution is drained from Tank 1 and Tank 2 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 in paragraphs (B)

and (C) above.

(b) Tank operation or operating time is defined as that time when a part is in the tank and the

rectifier is turned on. If the amount of time that no part is in the tank is fifteen minutes or

longer, that time is not considered operating time. Likewise, if the amount of time between

placing parts in the tank (i.e., when no part is in the tank) is less than fifteen minutes, that

time between plating the two parts may be considered operating time.

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.

A complete application for the purposes of this review was received on December 27, 1999.

Emission Calculations

Chromium emissions (Single HAP) from the biggest chromium electroplating source in Indiana are less

than ten (10) tons per year and CM Grinding, Inc. is a much smaller source in comparison. Therefore,

no emission calculations were necessary for the chromium electroplating because the chromium

emissions from this source will be less than ten (10) tons per year. Emission calculations for the

furnace are attached as pages 1 and 2 of 2 of TSD Appendix A.

Potential To Emit

Pursuant to 326 IAC 2-1.1-1(16), Potential to Emit is defined as “the maximum capacity of a stationary

source or emissions unit to emit any air pollutant under its physical and operational design. Any

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

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.”

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

per year. Therefore, the source is not subject to the provisions of 326 IAC 2-7.

(b) The potential to emit (as defined in 326 IAC 2-7-1(29)) of any single HAP is less than ten (10)

tons per year and the potential to emit (as defined in 326 IAC 2-7-1(29)) of a combination

HAPS is less than twenty-five (25) tons per year. Therefore, the source is not subject to the

provisions of 326 IAC 2-7.

(c) The existing source is subject to 326 IAC 20-8 but not subject to 326 IAC 2-5.5-1(b)(2),

Registration, because the source is not a decorative coating plant. The source is a hard

chromium electroplating source and the source emits less than major source levels (see (a)

and (b) above). Therefore, the source is subject to the provisions of 326 IAC 2-6.1-3(a).

Lead attainment

(a) Volatile organic compounds (VOC) and oxides of nitrogen are precursors for the formation of

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

attainment for ozone. Therefore, VOC and NOX emissions were reviewed pursuant to the

requirements for PSD, 326 IAC 2-2 and 40 CFR 52.21.

(b) St. Joseph County has been classified as attainment or unclassifiable for all other criteria

pollutants. Therefore, these emissions were reviewed pursuant to the requirements for

Prevention of Significant Deterioration (PSD), 326 IAC 2-2 and 40 CFR 52.21.

(c) Fugitive Emissions

Since this type of operation is not one of the 28 listed source categories under 326 IAC 2-2,

40 CFR 52.21, or 326 IAC 2-3 and since there are no applicable New Source Performance

Standards that were in effect on August 7, 1980, the fugitive particulate matter (PM) and

volatile organic compound (VOC) emissions are not counted toward determination of PSD and

Emission Offset applicability.

(a) 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 more, and it is not in one of the 28 listed

source categories.

(b) These emissions were based on the potential to emit of the entire source.

Part 70 Permit Determination

326 IAC 2-7 (Part 70 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/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)

applicable to this source.

Permit Reviewer: CAO/MES

(b) 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.

The hard chrome electroplating tanks, identified as Tank 1 and Tank 2, are subject to the

National Emission Standards for Hazardous Air Pollutants (NESHAPs), 326 IAC 14, (40 CFR

63, Subpart N, and 326 IAC 20-8-1). Pursuant to 40 CFR 63, Subpart N, and 326 IAC 20-8-1,

the tanks are subject to the following conditions:

(1) Emission limitation:

The Permittee shall comply with the requirements of this condition on and after the

compliance date for the tanks.

The hard chromium electroplating tanks, identified as Tank 1 and Tank 2 above, are

considered a small, existing hard chromium electroplating operation. During tank

operation, the Permittee shall control chromium emissions discharged to the

atmosphere from the hard chromium electroplating tanks by not allowing the concentration of total chromium in the exhaust gas stream discharged to the atmosphere

to exceed three-hundredths milligrams of total chromium per dry standard cubic meter

of ventilation air (0.03 mg/dscm) [equivalent to one and three-tenths times ten raised

to the power of negative five grains of total chromium per dry standard cubic foot of

ventilation air (1.3x10-5 gr/dscf)].

(2) Monitoring Requirements:

Pursuant to 40 CFR 63.343(c)(5)(ii) and (iii), when using a fume suppressant containing a wetting agent in the electroplating bath to comply with the limits specified

above, the Permittee shall monitor the surface tension and the temperature of the

electroplating baths. Operation of Tank 1 and Tank 2 at a surface tension greater

than the value established during a performance test shall constitute noncompliance

with the standards. The temperature shall not exceed 130 degrees Fahrenheit.

(A) The Permittee shall monitor the surface tension and temperature of the

electroplating bath during tank operation according to the following schedule:

(i) 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.

(ii) 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.
CM Grinding Inc. Page 7 of 8

South Bend, Indiana MSOP 141-11700-00190

Permit Reviewer: CAO/MES

(iii) 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 (B) above. For example, if a

Permittee had been monitoring a tank 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.

(B) Once a bath solution is drained from Tank 1 and Tank 2 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 in paragraphs (B) and (C) above.

Tank operation or operating time is defined as that time when a part is in the tank and

the rectifier is turned on. If the amount of time that no part is in the tank is fifteen

minutes or longer, that time is not considered operating time. Likewise, if the amount

of time between placing parts in the tank (i.e., when no part is in the tank) is less than

fifteen minutes, that time between plating the two parts is considered operating time.

(3) Reporting Requirements:

A summary report shall be prepared to document the ongoing compliance status of

the chromium electroplating operation. This report shall be completed annually,

retained on site, and made available to IDEM upon request. If there are significant

exceedance of chromium air emission limits (as defined in 40 CFR Part 63.347 (h)(2)),

then semiannual reports shall be submitted to:

Indiana Department of Environmental Management

Air Compliance Branch, Office of Air Management

Chromium Electroplating

100 North Senate Avenue, P.O. Box 6015

Indianapolis, Indiana 46206 

(4) The chromium electroplating operations shall be subject to the record keeping and

reporting requirement as indicated in the chromium electroplating NESHAP.
