Baycote Metal Finishing, Inc. Page 19 of 29

Mishawaka, Indiana MSOP 141-16170-00108

Permit Reviewer: CAP/MES

5.97 inches of water and the average outlet chromium concentration is 0.0046

mg/dscm.

(2) During the most recent performance test (February 20, 2001), it was determined

that the surface tension of the bath, using Method 306B, Appendix A of 40 CFR 63,

was 58.4 dynes/cm.

(b) The Permittee is not required to further test Chrome tank 1 by this permit. However, the

IDEM may require testing when necessary to determine if the tank is in compliance. If

testing is required by the IDEM, compliance with the limit 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 tank, the composite mesh pad system,

the wetting agent or monitoring equipment may require additional performance testing

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

IAC 20-8-1]

(a) Pursuant to 40 CFR 63.343(c)(1)(ii), when using a composite mesh-pad system to comply

with the limit specified in Condition D.1.3, the Permittee shall monitor and record the

pressure drop across the composite mesh-pad system during tank operation once each day

that the hard chromium electroplating tank is operating. To be in compliance with the

standards, the composite mesh-pad system shall be operated within the pressure drop

range established during the initial performance test, or within the range of compliant values

for pressure drop established during multiple performance tests.

(b) Pursuant to 40 CFR 63.343(c)(5)(ii) and (iii), when using a wetting agent in the electroplating bath to comply with the limit specified in Condition D.1.3, the Permittee shall monitor

the surface tension of the electroplating baths. Operation of Chrome tank 1 at a surface

tension greater than the value established during a performance test shall constitute

noncompliance with the standards.

(1) The Permittee shall monitor the surface tension 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 every 8

hours of tank operation. Once there are no exceedances during 40 hours

of tank operation, surface tension measurement may be conducted once

per day, with no more than 40 hours of tank operation between

measurements 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.
Baycote Metal Finishing, Inc. Page 20 of 29

Mishawaka, Indiana MSOP 141-16170-00108

Permit Reviewer: CAP/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 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.

(2) Once a bath solution is drained from Chrome tank 1 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.

(c) 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.

County: St. Joseph

SIC Code: 3471

Operation Permit No.: MSOP 141-16170-00108

Permit Reviewer: CarrieAnn Paukowits 

The Office of Air Quality (OAQ) has reviewed an application from Baycote Metal Finishing, Inc.

relating to the operation of a chromium electroplating source.

Permitted Emission Units and Pollution Control Equipment

There are no permitted facilities operating at this source during this review process.

Unpermitted Emission Units and Pollution Control Equipment

The source also consists of the following unpermitted facilities/units that did not require permits

under 326 IAC 2-1, but require permits under 326 IAC 2-5 and 326 IAC 2-6:

(a) One (1) hard chrome plating tank, identified as Chrome tank 1, constructed in February

1997, using a hexavalent chromium bath and having a rectifier capacity of 4,000 amps and

a maximum cumulative rectifier capacity of 23,520,000 amp-hours, equipped with a composite mesh pad system and a mist suppressant containing a wetting agent as controls, and

exhausting to the chrome stack.

(b) One (1) natural gas-fired boiler, constructed in 1967, exhausting to the boiler stack, heat

input capacity: 5.3737 million British thermal units per hour.

New Emission Units and Pollution Control Equipment

There are no new facilities proposed at this source during this review process.

Existing Approvals

The source has no previous approvals.

Enforcement Issue

(a) The applicant applied for the Minor Source Operating Permit (MSOP) after December 27,

1999. Therefore, the source is not in compliance with the compliance schedule under 326

IAC 2-6.1-3.

(b) IDEM is reviewing this matter and will take appropriate action.

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 September 30, 2002, with additional

information received on October 17 and November 1, 2002.

Emission Calculations

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

less than ten (10) tons per year and Baycote Metal Finishing, 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. See

Appendix A (pages 1 and 2 of 2) of this document for detailed emissions calculations for the boiler.

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 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 decorative coating instead

of trivalent chromium and the source emits less than major source levels. Therefore, the

source is subject to the provisions of 326 IAC 2-6.1-3(a).

(b) 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 particulate matter (PM) and volatile organic

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

Offset applicability.

(a) Volatile organic compounds (VOC) are precursors for the formation of ozone. Therefore,

VOC emissions are considered when evaluating the rule applicability relating to the ozone

standards. St. Joseph County has been designated as attainment or unclassifiable for

ozone. Therefore, VOC emissions were reviewed pursuant to the requirements for

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

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

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.

Part 70 Permit Determination

326 IAC 2-7 (Part 70 Permit Program)

This existing source based on the emissions summarized in this permit, MSOP 141-16170, is not

subject to the Part 70 Permit requirements because the potential to emit (PTE) of:

(a) each criteria pollutant is less than one hundred (100) tons per year,

(b) a single hazardous air pollutant (HAP) is less than ten (10) tons per year, and
Baycote Metal Finishing, Inc. Page 5 of 10

Mishawaka, Indiana MSOP 141-16170-00108

Permit Reviewer: MES

(c) any combination of HAPs is less than twenty-five (25) tons per year.

This is the first air approval issued to this 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.

(b) The one (1) natural gas-fired boiler is not subject to the requirements of 40 CFR 60.40,

60.40a, 60.40b or 60.40c (Subparts D, Da, Db and Dc) because it was constructed prior to

August 17, 1971, which is the earliest applicability date of these rules.

(c) The one (1) chromium electroplating tank, identified as Chrome tank 1, is subject to the

National Emission Standards for Hazardous Air Pollutants, 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 chromium electroplating operations are subject to the following conditions:

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

compliance date for the tank.

The hard chromium electroplating tank, identified as Chrome tank 1, is considered

a small, new hard chromium electroplating operation. During tank operation, the

Permittee shall control chromium emissions discharged to the atmosphere from the

tank by not allowing the concentration of total chromium in the exhaust gas stream

discharged to the atmosphere to exceed fifteen-thousandth milligrams of total

chromium per dry standard cubic meter of ventilation air (0.015 mg/dscm) [equivalent to six and six-tenths times ten raised to the power of negative six grains of total

chromium per dry standard cubic foot of ventilation air (6.6x10-6 gr/dscf)].

(2) Monitoring Requirements

(A) Pursuant to 40 CFR 63.343(c)(1)(ii), when using a composite mesh-pad

system to comply with the limit specified above, the Permittee shall monitor

and record the pressure drop across the composite mesh-pad system

during tank operation once each day that the hard chromium electroplating

tank is operating. To be in compliance with the standards, the composite

mesh-pad system shall be operated within the pressure drop range established during the initial performance test, or within the range of compliant

values for pressure drop established during multiple performance tests.

(B) Pursuant to 40 CFR 63.343(c)(5)(ii) and (iii), when using a wetting agent

in the electroplating bath to comply with the limit specified above, the

Permittee shall monitor the surface tension of the electroplating baths.

Operation of Chrome tank 1 at a surface tension greater than the value

established during a performance test shall constitute noncompliance with

the standards. The Permittee shall monitor the surface tension 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
Baycote Metal Finishing, Inc. Page 6 of 10

Mishawaka, Indiana MSOP 141-16170-00108

Permit Reviewer: MES

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

per day, with no more than 40 hours of tank operation between

measurements 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.

(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.

Once a bath solution is drained from Chrome tank 1 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.

(C) 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.

(3) Reporting Requirements

The notifications and reports required in this section shall be submitted to IDEM,

OAQ using the address specified in Section C - General Reporting Requirements.

(A) Notifications:

(i) Initial Notifications

The Permittee shall notify IDEM, OAQ in writing that the source is

subject to 40 CFR Part 63, Subpart N. The notification shall be

submitted no later than one hundred eighty (180) days after the

compliance date and shall contain the information listed in 40 CFR

63.347(c)(1). 

(ii) A Notification of Compliance Status (NCS) is required each time

that the facility becomes subject to the requirements of 40 CFR

Part 63 Subpart N. The NCS shall be submitted to IDEM, OAQ,

and shall list, for each tank, the information identified in 40 CFR
Baycote Metal Finishing, Inc. Page 7 of 10

Mishawaka, Indiana MSOP 141-16170-00108

Permit Reviewer: MES

63.347(e)(2). The NCS for Chrome tank 1 shall be submitted to

IDEM, OAQ immediately.

(iii) Notification of Construction or Reconstruction

Pursuant to 40 CFR 63.345(b)(1), the Permittee may not construct

a new tank subject to 40 CFR 63, Subpart N (including nonaffected tanks defined in 40 CFR 63.344(e)) without submitting a

Notification of Construction or Reconstruction (NCR) to IDEM,

OAQ. In addition, the Permittee may not change, modify, or reconstruct Chrome tank 1 without submitting a Notification of Construction or Reconstruction (NCR) to IDEM, OAQ. The NCR shall

contain the information identified in 40 CFR 63.345(b) (2) and (3).

A change, modification, or reconstruction of this facility includes

any change in the air pollution control techniques, the addition of

add-on control devices, or the construction of duct work for the

purpose of controlling both existing tanks and non-affected facilities by a common control technique or device. A complete application to construct new chromium electroplating or chromium

anodizing tanks serves as this notification. Likewise, the complete

application to modify or reconstruct Chrome tank 1 serves as this

notification. Pursuant to 326 IAC 2-1.1-2(a), permission must be

received from IDEM, OAQ before construction, modification, or

reconstruction may commence.

(B) Performance Test Results

The Permittee shall document results from any future performance tests

in a complete test report that contains the information required in 40 CFR

344(a).

The Permittee shall submit reports of performance test results as part of

the Notification of Compliance Status, described in 40 CFR 63.347(e), no

later than forty-five (45) days following the completion of the performance

test.

(C) Ongoing Compliance Status Report

The Permittee shall prepare summary reports to document the ongoing

compliance status of Chrome tank 1 using the Ongoing Compliance Status

Report form provided with this permit. This report shall contain the information specified in 40 CFR 63.347(g)(3). Because Chrome tank 1 is

located at a site that is an area source of hazardous air pollutants (HAPs),

the Ongoing Compliance Status Report shall be retained on site and made

available to IDEM, OAQ upon request. 

(D) If both of the following conditions are met, semiannual reports shall be

prepared and submitted to IDEM, OAQ:

(i) The total duration of excess emissions (as indicated by the monitoring data collected by the Permittee in accordance with 40 CFR

63.343(c)) is one percent (1%) or greater of the total operating

time as defined above for the reporting period; and

(ii) The total duration of malfunctions of the add-on air pollution control device and monitoring equipment is five percent (5%) or
Baycote Metal Finishing, Inc. Page 8 of 10

Mishawaka, Indiana MSOP 141-16170-00108

Permit Reviewer: MES

greater of the total operating time as defined above.

Once the Permittee reports an exceedance as defined above, Ongoing

Compliance Status Reports shall be submitted semiannually until a request

to reduce reporting frequency in accordance with 40 CFR 63.347(g)(2) is

approved. IDEM, OAQ 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.

State Rule Applicability - Entire Source

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

Construction of the hard chromium electroplating source, that commenced prior to August 7, 1977,

was not subject to the requirements of 326 IAC 2-2, PSD. The source, modified in 1997, is still not

subject to the requirements of 326 IAC 2-2 because the potential to emit each criteria pollutant is

less than 250 tons per year.

326 IAC 2-6 (Emission Reporting)

This source is located in St. Joseph County, the potential to emit VOC and NOX are less than ten

(10) tons per year, and the potentials to emit CO, PM10 and SO2 are less than one hundred (100)

tons per year. Therefore, 326 IAC 2-6 does not apply.

326 IAC 5-1 (Opacity Limitations)

This source is located north of Kern Road and East of Pine Road in St. Joseph County. Therefore,

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 nonoverlapping integrated averages for a continuous opacity

monitor) in a six (6) hour period.

State Rule Applicability - Individual Facilities

326 IAC 6-1 (Nonattainment Area Limitations)

Pursuant to 326 IAC 6-1-1, this source is not subject to the requirements of 326 IAC 6-1 because

it is not mentioned in 326 IAC 6-1-8.1 through 6-1-18 and the source does not have potential PM

emissions of one hundred (100) tons per year or more or actual PM emissions of ten (10) tons per

year or more.

326 IAC 6-2-3 (Particulate Emissions Limitations for Facilities Constructed prior to September 21, 1983)

The one (1) boiler constructed in 1967, with a heat input capacity of 5.3737 million British thermal

units per hour, must comply with the PM emission limitation of 326 IAC 6-2-3. This limitation is

based on the following equation is given in 326 IAC 6-2-3:

Pt = C x a x h / 76.5 x Q0.75 x N0.25

where:

Pt = Pounds of particulate matter emitted per million British thermal units (lb/MMBtu) heat

input

Q = Total source maximum operating capacity rating in million British thermal units per

hour (MMBtu/hr) heat input. The maximum operating capacity rating is defined as the

maximum capacity at which the facility is operated or the nameplate capacity, whichever is specified in the facility’s permit application, except when some lower capacity

is contained in the facility’s operation permit; in which case, the capacity specified in

the operation permit shall be used.

C = Maximum ground level concentration with respect to distance from the point source

at the “critical” wind speed for level terrain. This shall equal 50 micrograms per cubic

meter for a period not to exceed a sixty (60) minute time period.

N = Number of stacks in fuel burning operation.

a = Plume rise factor which is used to make allowance for less than theoretical plume rise.

The value 0.67 shall be used for Q less than or equal to 1,000 mmBtu/hr heat input.

The value 0.8 shall be used for Q greater than 1,000 mmBtu/hr heat input.

h = Stack height in feet.

For the one (1) boiler:

Pt = 50 x 0.67 x 27.08 / 76.5 x (5.3737)0.75 x 10.25 = 3.36 lb/MMBtu

Pursuant to 326 IAC 6-2-3(d), particulate emissions from all facilities used for indirect heating

purposes which were existing and in operation on or before June 8, 1972, shall in no case exceed

0.8 lb/mmBtu heat input. Therefore, the one (1) boiler is limited to emissions of 0.8 pound per

million British thermal units.

Based on Appendix A, the potential to emit PM emissions from the one (1) boiler limited to 0.8

pound PM per million British thermal units is:

0.045 tons/yr × (2000 lbs/ton / 8760 hrs/yr) = 0.010 lb/hr

(0.010 lb/hr / 5.3737 MMBtu/hr) = 0.002 lb PM per MMBtu

Therefore, the one (1) boiler will comply with this rule.

326 IAC 6-3 (Particulate Emission Limitations for Manufacturing Processes)

Pursuant to 326 IAC 6-3-1(c)(6), this rule is not applicable to the chrome electroplating operations

because a particulate limit for the electroplating is established in 326 IAC 20-8-1.

**Emission Factors for NOx: Uncontrolled = 100, Low NOx Burner = 50, Low NOx Burners/Flue gas recirculation = 32

Methodology

All emission factors are based on normal firing.

Heat input capacity (MMBtu/hr) = (Steam Generating capacity x 1.7E3)/1000000

MMBtu = 1,000,000 Btu

MMCF = 1,000,000 Cubic Feet of Gas

Potential Throughput (MMCF) = Heat Input Capacity (MMBtu/hr) x 8,760 hrs/yr x 1 MMCF/1,000 MMBtu

Emission Factors are from AP 42, Chapter 1.4, Tables 1.4-1, 1.4-2, 1.4-3, SCC #1-02-006-02, 1-01-006-02, 1-03-006-02, and 1-03-006-03

(SUPPLEMENT D 3/98)

Emission (tons/yr) = Throughput (MMCF/yr) x Emission Factor (lb/MMCF)/2,000 lb/ton

Note: Check the applicable rules and test methods for PM and PM10 when using the above emission factors to confirm that the

correct factor is used (i.e., condensable included/not included).
