finishing surface grinder shall be limited to less than 19.2 pounds per hour when operating

of a process weight rate of 20,000 pounds per hour. 

The limitations were calculated using the following equation:

Interpolation and extrapolation of the data for the process weight rate up to sixty thousand (60,000)

pounds per hour shall be accomplished by use of the equation:

E = 4.10 P 0.67 where E = rate of emission in pounds per hour and 

 P = process weight rate in tons per hour

D.2.2 Particulate Matter Limitation (PM) [326 IAC 6-2-4]

Pursuant to 326 IAC 6-2-4(a), for Q less than 10 million British thermal units per hour, Pt shall not

exceed 0.6 pound per million British thermal units. Since the emission limitation calculated in the

following equation is greater than 0.6 pounds per million British thermal unit, each of the three (3)

boilers are limited to emissions of 0.6 pound per million British thermal units.

Pt = 1.09/Q0.26

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.

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

D.2.3 Testing Requirements [326 IAC 2-1.1-11]

The Permittee is not required to test this emissions unit by this permit. However, IDEM may require

SIC Code: 3470

Permit Reviewer: CarrieAnn Ortolani

On February 15, 2000, the Office of Air Management (OAM) had a notice published in the Chesterton

Tribune, Chesterton, Indiana, stating that Chrome Deposit Corporation had applied for a Minor Source

Operating Permit to operate stationary chromium electroplating source with evaporator/coolers and packed

bed/ composite mesh pad scrubbers as control. The notice also stated that OAM proposed to issue a permit

for this installation and provided information on how the public could review the proposed permit and other

documentation. Finally, the notice informed interested parties that there was a period of thirty (30) days to

provide comments on whether or not this permit should be issued as proposed.

On March 10, 2000, Ronald A. Bahr, Vice President of Liberty Engineering, Inc., consultant to the

applicant, and George Wright, Plant Manager of Chrome Deposit Corporation, submitted comments on the

proposed construction permit. The comments and corresponding responses are as follows: The permit

language, if changed, has deleted language as strikeouts and new language bolded.

Comment 1:

Page 4 - Section A.2(d), Page 20 - Section D.2, Technical Support Document - Page 1(d): The permit

application specified two atmospheric evaporators associated with the spent wash water holding

tanks. Please revise the wording to include the spent wash water atmospheric evaporators. We

would suggest wording such as the following:

Two (2) spent wash water holding tanks identified, as Nos. 1 and 2, with associated atmospheric

evaporators exhausting to stacks WR#1 and WR#2 .

Response 1:

Section A.2(d) and the facility description (f), now (d), in Section D.2 have been revised as follows:

Two (2) spent wash water holding tanks, identified as Nos. 1 and 2, with associated atmospheric

evaporators, exhausting to stacks WR#1 and WR#2.

Comment 2:

Page 4 - Section A.2(e), Page 20 - Section D.2, Technical Support Document -Page 1 (e) and Page

8 - State Rule Applicability: The permit application specified three hot water boilers constructed in

August, 1994 with heat exchangers. Please revise the wording to correct the construction date and

to include the heat exchangers. We would suggest wording such as the following:

Three (3) hot water boilers, constructed in 1994, fired by natural gas, exhausting to stacks

B1, B2, and B3, capacity 0.413 million BTUH each, with associated heat exchangers.

Response 2:

Section A.2 (e) and the facility description (g), now (e), in Section D.2 have been revised as follows:

Three (3) hot water boilers, constructed in 1984, fired by natural gas, with associated heat

exchangers, exhausting to stacks B1, B2 and B3, capacity: 0.413 million British thermal units per

hour, each.

Comment 3:

Pages 6 & 7 - Section B, General Construction Conditions - Paragraphs B.4 through B.6: The

application which was made to IDEM as required under the Indiana Administrative Codes (IAC) was

for a minor source operating permit. The three paragraphs B.4 through B.6 are written for a

construction permit. Since the application is for existing equipment at an existing plant which has not

previously required an operating permit under IAC regulations we question that the three paragraphs

may be misleading and unnecessary. If for some administrative reason IDEM considers the

construction permit wording necessary for this existing equipment please tell us.

Response 3:

Section B has been replaced with the following Section B:

SECTION B GENERAL CONSTRUCTION CONDITIONS

Permit Reviewer: MES

modified in a manner consistent with procedures established for modifications of operating

permits pursuant to 326 IAC 2 (Permit Review Rules).

Comment 4:

Page 6 - Paragraph B.6(a): If the paragraph is determined to be necessary the referenced “attached

Affidavit of Construction” is missing from the draft permit. Please provide the document if the paragraph is considered necessary so we may review it during this draft review phase.

Response 4:

Condition B.6 has been removed as indicated in Response 3.

Comment 5:

Page 9 - Paragraph C.4(e): The use of photographic equipment within the facility is considered

confidential due to proprietary methods and processes being used at the facility. We would request

that the paragraph be revised to acknowledge that all photographs taken inside the facility are confidential and must be treated as such.

Response 5:

Condition C.4 (e) has been revised as follows:

(e) Utilize any photographic, recording, testing, monitoring, or other equipment for the purpose

of assuring compliance with this permit or applicable requirements. [326 IAC 2-7-6(6)]

(1) The Permittee may assert a claim that, in the opinion of the Permittee,

information removed or about to be removed from the source by IDEM, OAM,

or an authorized representative, contains information that is confidential

under IC 5-14-3-4(a). The claim shall be made in writing before or at the time

the information is removed from the source. In the event that a claim of

confidentiality is so asserted, neither IDEM, OAM, nor an authorized

representative, may disclose the information unless and until IDEM, OAM,

makes a determination under 326 IAC 17-1-7 through 326 IAC 17-1-9 that the

information is not entitled to confidential treatment and that determination

becomes final. [IC 5-14-3-4; IC 13-14-11-3; 326 IAC 17-1-7 through 326 IAC 17-

1-9]

(2) The Permittee, and IDEM, OAM, acknowledge that the federal law applies to

claims of confidentiality made by the Permittee with regard to information

removed or about to be removed from the source by U.S. EPA. [40 CFR Part

2, Subpart B]

Comment 6:

Page 9 - Paragraph C.6: The wording of this paragraph identifies the document as “This permit to

construct and operate”. As indicated in Comment #3 we are applying for a minor source operating

permit. Unless there is some administrative reason which requires this to also be a construction

permit we would request that the wording be modified to indicate that this is a permit to operate.

Response 6:

Condition C.6 is revised as follows:
Chrome Deposit Corporation Page 5 of 20

Portage, Indiana MSOP 127-11699-00093

Permit Reviewer: MES

C.6 Permit Revocation [326 IAC 2-1-9]

Pursuant to 326 IAC 2-1-9(a)(Revocation of Permits), this permit to construct and operate may be

revoked for any of the following causes:

(a) Violation of any conditions of this permit.

(b) Failure to disclose all the relevant facts, or misrepresentation in obtaining this permit.

(c) Changes in regulatory requirements that mandate either a temporary or permanent reduction of discharge of contaminants. However, the amendment of appropriate sections of this

permit shall not require revocation of this permit.

(d) Noncompliance with orders issued pursuant to 326 IAC 1-5 (Episode Alert Levels) to reduce

emissions during an air pollution episode.

(e) For any cause which establishes in the judgment of IDEM, the fact that continuance of this

permit is not consistent with purposes of this article.

Comment 7:

Page 11 - Paragraph C.12(b): Under the conditions of the federal NESHAP and this draft permit

(Paragraph D.1.5) the facility is only required to check the primary compliance parameter, the

pressure drop across the mesh pad of each scrubber, once per day. An exceedance occurs if this

pressure drop reading exceeds the limits determined by performance testing. The operating time of

the unit outside of the limits is known to be no greater than the operating time of the system since the

previous compliance reading. Since the wording of paragraph C.12 (b) requires notification within 4

daytime business hours of a malfunction and the wording of paragraph D.1.5 requires only daily

readings, we are requesting that the notification wording be modified to define the beginning of the

malfunction for purposes of this notification to be that time when the personnel first have knowledge

of the malfunction. Normal procedures in place at Chrome Deposit Corp. utilize readings on an eight

hour basis rather than 24 hours in order to anticipate any problems and also require shut-down of the

unit as soon as the readings approach the pressure drop limits.

We would also request that the term daytime business hours be defined and notification telephone

and facsimile numbers be written into paragraph C.12 to ensure proper communications.

Response 7:

The language used in Condition C.12 is identical to the language used in 326 IAC 1-6-2. The

telephone number is (317) 233-0178 and the facsimile number is (317) 233-5967. The facsimile

number is provided on the Malfunction Report Form. Daytime business hours are 9AM to 5PM. A

malfunction cannot be reported until it is discovered and a malfunction cannot be assumed to have

begun until it is discovered. Therefore, since Condition C.12 uses the same language as 326 IAC 1-

6-2, there are no changes to the permit as a result of this comment.

Comment 8:

Page 13 - Paragraph C.14 (c)(4): This paragraph refers to:

“response steps performed in accordance with the Compliance Response Plan required by

Section C - Compliance Monitoring Plan - Failure to take Response Steps, of this permit,”.

The draft permit does not contain this section. Please remove this paragraph from the permit or revise

the draft permit to include the referenced section.
Chrome Deposit Corporation Page 6 of 20

Portage, Indiana MSOP 127-11699-00093

Permit Reviewer: MES

Response 8:

Condition C.14 (c)(4) shall be revised as follows:

(4) Records of preventive maintenance shall be sufficient to demonstrate that failure to

implement the Preventive Maintenance Plan did not cause or contribute to a violation of any

limitation on emissions or potential to emit. To be relied upon subsequent to any such

violation, these records may include, but are not limited to: work orders, parts inventories,

and operator’s standard operating procedures. Records of response steps taken shall

indicate whether the response steps were performed in accordance with the Compliance

Response Plan required by Section C - Compliance Monitoring Plan - Failure to take

Response Steps, of this permit, and whether a deviation from a permit condition was

reported. All records shall briefly describe what maintenance and response steps were

taken and indicate who performed the tasks.

Page 13 - Paragraph C.15, Page 14 - Paragraph C.16, Page 19 - Paragraph D.1.8, Page 24 & 25 -

Ongoing Compliance Status Report, Page 26 - Minor Source Operating Permit Annual Notification:

Under the federal NESHAP requirements for an area source such as Chrome Deposit Corporation

a source which is in compliance with the regulation is required to prepare an annual summary report

documenting the ongoing compliance of the facility and retain the report on-site. If particular levels

are exceeded as defined in 40 CFR Part 63.347((h)(2) a semi-annual report is submitted to the

Administrator.

Under the draft permit, a source which is in compliance with the federal regulation and the state

permit is required to prepare and submit five separate reports at different times to the Office of Air

Management.

We realize that IDEM has the authority under 326 IAC 2-6.1-2 to require reporting as needed to

ensure compliance, but we feel that the increased reporting levels proposed in the draft permit are

causing a significant paperwork burden on the facility which could be reduced if the federal NESHAP

standard or an annual format was followed without compromising compliance monitoring. The variety

of reports required in the draft permit at different times, i.e.,

March 1 of the following year for the prior calendar year (C.16(c)) for the annual notice

Seven months after issuance of the permit (C.15) for Semi-annual Compliance Monitoring Report

Thirteen months after issuance of the permit (C.15) for Semi-annual Compliance Monitoring Report

July 30 (D.1.8(d)(1)) for Ongoing Compliance Status Report

January 30 (D.1.8(d)(1)) for Ongoing Compliance Status Report

even when the source is in full compliance seem questionable in our opinion in ensuring the compliance of the facility. Based upon our experience at facilities in other states an annual summary report

submitted to the Compliance Data Section of the Office of Air Management which includes all of the

information outlined in the five reports specified in the draft permit could certainly ensure compliance

when a source has been in compliance throughout the year. We are requesting that the five reports

outlined in the draft permit be combined into one annual summary report which the facility would

submit to IDEM.

Response 9:

The reports required by Conditions C.15 and C.16 are necessary for compliance with 326 IAC 2-6.1-2

and 326 IAC 2-6.1-5(a)(5). The reporting requirements previously in Condition D.1.8 are revised in

Condition D.1.10 as a result of the IDEM changes presented at the end of this document. As

indicated in Condition D.1.10, Ongoing Compliance Status Reports are only prepared annually and
Chrome Deposit Corporation Page 7 of 20

Portage, Indiana MSOP 127-11699-00093

Permit Reviewer: MES

are kept on site if the tanks remain in compliance. The reports required by D.1.10 are necessary for

compliance with 40 CFR 63.345 and 40 CFR 63.347. 

Comment 10:

Page 15 - Paragraph D.1.2(b)(1), paragraph D.1.2(b)(4)(B), paragraph D.1.3, paragraph D.1.4(a),

paragraph D.1.4(c), paragraph D.1.7, paragraph D.1.8: The control system is a combination packed

bed/composite mesh pad system for both scrubbers B and C/D. Please revise the description.

Response 10:

The control device description has been revised in Section D.1. For clarity, the revisions are indicated

along with the IDEM changes presented at the end of this document.

Comment 11:

Page 17 - Paragraph D.1.4(d): To avoid confusion please define “working days” for the permit as

used in this paragraph. Are these working days for IDEM, Monday - Friday, or working days for

Chrome Deposit Corp., seven days a week?

Response 11:

Condition D.1.4(d), now D.1.6(d), refers to working days for Chrome Deposit Corporation.

Comment 12:

Page 17 - Paragraphs D.1.5: A typographical error shows two paragraphs (b).

Response 12:

Condition D.1.5 has been revised as indicated in the IDEM changes presented at the end of this

document.

Comment 13:

Page 17 - Paragraphs D.1.5(c) and (d), Technical Support Document - Page 7 & 8 (d) (2) & (3): We

request that the change which is being proposed by the USEPA for the chromium electroplating

NESHAP regarding the increase of the upper limit from + 1 inch of water column to + 2 inches of

water column be addressed in this section of the permit in a manner which will allow the change to

be adopted once it is part of the federal NESHAP without changing the permit.

Response 13:

The current requirement is for an upper limit of +1 inch of water column. If the requirement changes

in the future, the permit can be revised.

Comment 14:

Page 18 - Paragraph D.1.7(a): It would seem that the wording “compliance with Conditions D.1.1 and

D.1.4" might be in error. Should the wording should have been - compliance with Conditions D.1.1

through D.1.5 ?

The draft permit refers to maintaining records “using the forms provided with this permit”. No forms

were provided with the draft permit. Please provide the forms which are being referred to so that they

may be reviewed. The facility currently utilizes its own standard forms for this record keeping require-

ment.

Response 14:

Condition D.1.7 has been revised as indicated in the IDEM changes at the end of this document.

Comment 15:

Page 19 - Paragraph D.1.7(b): As discussed in our telephone conversation there is no current federal

definition of “operating time” related to the chromium electroplating NESHAP. We feel that the definition being proposed in the draft permit may be suitable for a more traditional hard chrome electroplating facility in which the typical time when the rectifier is active is in the range of ten hours or more.

Since the typical plating time for items at Chrome Deposit Corporation is in the range of ten minutes

and the typical time between rolls is in the range of 15 minutes the proposed definition results in what

we feel is both an inaccurate and difficult measurement.

We propose either of two options for the definition of “operating time”. Option one would count the

entire time the operators are on the job as operating time. In this definition a 24 hour day would be

counted as 24 hours of operation if operators were staffing the system for the whole day. This option

is the current definition of operating time being used at the facility.

A second option would involve the installation of non-resettable hour meters on the two systems. The

hour meters would record the time a rectifier was providing power to the system as “operating time”.

In system C/D which utilizes two stations the operating time would be counted as any time either

station was supplied with power, but would not double the operating time if both stations were active.

Response 15:

Non-resettable hour meters will be necessary to record the time a rectifier was providing power to the

system, and, thus, determine operating time.

Comment 16:

Page 20 - Section D.2: A typographical error begins the emissions unit listing with (e) rather than (a).

Response 16:

The lettering in the Emissions Unit Description Box should match the lettering for the same equipment

in Section A.2. The Emissions Unit Description Box in Section D.2 has been revised as follows:

(The information describing the process contained in this emissions unit description box is descriptive

information and does not constitute enforceable conditions.)

Comment 17:

Page 20 - Paragraph D.2.1(a): The regulation refers to emissions from the process. Since the

emissions are ducted through the Torit air filters we feel that the wording of this paragraph should

indicate that the limit is imposed on the emissions from the air filter unit, not the input into this control

unit.

Permit Reviewer: MES

Response 17:

Condition D.2.1 is revised as follows:

D.2.1 Particulate Matter (PM) [326 IAC 6-3-2]

(a) Pursuant to 326 IAC 6-3-2 (Process Operations), the particulate matter (PM) from each of

the two (2) EDT machines shall be limited to less than 19.2 pounds per hour, each, taking

into account control by the torit air filters, when operating of a process weight rate of

20,000 pounds per hour, each.

(b) Pursuant to 326 IAC 6-3-2 (Process Operations), the particulate matter (PM) from each of

the wet finishing surface grinder shall be limited to less than 19.2 pounds per hour when

operating of a process weight rate of 20,000 pounds per hour. 

The limitations were calculated using the following equation:

Interpolation and extrapolation of the data for the process weight rate up to sixty thousand (60,000)

pounds per hour shall be accomplished by use of the equation:

E = 4.10 P 0.67 where E = rate of emission in pounds per hour and 

 P = process weight rate in tons per hour

Comment 18:

Page 21 - Paragraph D.2.1(b): The wording of the paragraph could be changed to eliminate the

phrase “from each of” since there is only one surface grinder.

Page 21 - Paragraph D.2.2, Technical Support Document - Page 8 - State Rule Applicability: In our

opinion each boiler is limited to 0.6 pound per million BTU’s under the regulation. We request that

the phrase “the three (3) boilers are limited to emissions of 0.6 pound per million British thermal units”

be changed to indicate that each of the three boilers is limited to emissions of 0.6 pound per million

British thermal units.

Response 19:

For clarity, Condition D.2.2 is revised as follows:

D.2.2 Particulate Matter Limitation (PM) [326 IAC 6-2-4]

Pursuant to 326 IAC 6-2-4(a), for Q less than 10 million British thermal units per hour, Pt shall not

exceed 0.6 pound per million British thermal units. Since the emission limitation calculated in the

following equation is greater than 0.6 pounds per million British thermal unit, each of the three (3)

boilers are limited to emissions of 0.6 pound per million British thermal units.

Pt = 1.09/Q0.26

where:

Permit Reviewer: MES

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.

Technical Support Document - Page 2 Stack Summary: Please revise the items in the Operation

column “Spent wash water tank #1 & #2” to include the associated atmospheric evaporator #1 and

#2 which is the actual part of the system exhausting to stacks WR#1 and WR#2 as outlined in the

permit application.

Response 20:

The OAM prefers that the Technical Support Document reflect the permit that was on public notice.

Changes to the permit or technical support material that occur after the public notice are

documented in this Addendum to the Technical Support Document. This accomplishes the desired

result of ensuring that these types of concerns are documented and part of the record regarding this

permit decision. The fact described in this comment is noted in this Addendum to the TSD, and the

permit is corrected as indicated in Response 1.

Comment 21:

Technical Support Document - Page 4 Potential to Emit (c) and Page 6 Part 70 Permit Determination:

There is a clarification necessary.

In the section on Potential to Emit(c) on page 4 of the TSD the draft permit states that the existing

source is subject to 326 IAC 20-8. As a deferred source under paragraph 326 IAC 20-8 as it is

currently published on the IAC website the regulation shows a requirement to submit a Part 70 application by Dec. 9, 2000. This is the date which previously was required by the federal NESHAP for

area sources prior to the federal allowance of an extension to Dec. 9, 2005 if allowed by permitting

authorities.

In the section on Part 70 Permit Determination on page 6 of the TSD the draft permit states that the

existing source is not subject to the Part 70 Permit requirements.

Please reword the MSOP draft permit to indicate if and when a Part 70 permit application is due in

the future. As currently worded the draft permit is not clear on this requirement.

Response 21:

A Part 70 permit is currently not required for this source. As indicated in Condition B.1, this permit

to operate does not relieve the Permittee of the responsibility to comply with the provisions of the
Chrome Deposit Corporation Page 12 of 20

Portage, Indiana MSOP 127-11699-00093

Permit Reviewer: MES

Indiana Environmental Management Law (IC 13-11 through 13-20; 13-22 through 13-25; and 13-

30), the Air Pollution Control Law (IC 13-17) and the rules promulgated thereunder, as well as other

applicable local, state, and federal requirements. There are not changes to the permit as a result

of this comment.

Comment 22:

Technical Support Document - Page 7 Federal Rule Applicability (c): In our opinion the draft permit

has exceeded the regulatory requirements of 40CFR 63 Subpart N which is adopted in 326 IAC 20-8-

1. The normal requirement for an Ongoing Compliance Status report is annually. The only time that

a semi-annual report is required is in the event of specific exceedances as outlined in 40CFR63.347

(h)(2). If both of the conditions of (1) excess emissions greater than 1% of the operating time, and

(2) malfunctions of the scrubber greater than 5% of the total operating time occur the regulation

requires semi-annual submittal of the ongoing compliance report until a request to reduce the frequency is approved.

It seems that the draft permit is promulgating more stringent requirements for a source that is not in

violation of published regulations. This does not seem to be a reasonable approach to the regulatory

process. More is not necessarily better. The federal and state regulations give IDEM the authority

to require this more frequent reporting on a case-by-case basis. Since the facility is and has been

in full compliance we question the need to impose these more stringent requirements in this case.

Response 22:

The requirements for the Ongoing Compliance Status Report are revised in Condition D.1.10(c) in

the IDEM changes presented below.

IDEM Changes

Upon further review, the OAM has decided to make the following changes to Section D.1 of the Minor

Source Operating Permit. The permit language is changed to read as follows (deleted language appears as

strikeouts, new language is bolded):

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 December 22, 1999, with additional

information received on January 25, 2000.

Emission Calculations

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

less than ten (10) tons per year and Chrome Deposit Corporation 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 through 5) of this document for detailed emissions calculations for combustion

and machining and grinding operations.

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 250

tons per year and the potentials to emit VOC and NOX are less than twenty-five (25) 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).

State Rule Applicability - Entire Source

326 IAC 2-6 (Emission Reporting)

This source is located in Porter County and the potential to emit VOC and NOX is less than ten (10)

tons per year. The potential to emit PM10 is less than one-hundred (100) tons per year. Therefore,

326 IAC 2-6 does not apply.

326 IAC 5-1 (Opacity Limitations)

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 forty percent (40%) 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 6-2-4 (Particulate Emissions Limitations for Facilities Constructed after September 21, 1983)

The three (3) boilers, known as B1, B2 and B3, all constructed in 1984, with a total heat input

capacity of 1.24 million British thermal units per hour, must have PM emissions of no more than 0.6

pound per million British thermal units in order to comply 326 IAC 6-2-4. The following equation is

given in 326 IAC 6-2-4:

Pt = 1.09/Q0.26

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
Chrome Deposit Corporation Page 9 of 9

Portage, Indiana MSOP 127-11699-00093

Permit Reviewer:MES

the operation permit shall be used.

For the three (3) boilers:

Pt = 1.09/(1.24)0.26 = 1.03 lb/MMBtu heat input

Pursuant to 326 IAC 6-2-4(a), for Q less than 10 million British thermal units per hour, Pt shall not

exceed 0.6 pound per million British thermal units. Therefore, the three (3) boilers are limited to

emissions of 0.6 pound per million British thermal units.

Based on Appendix A, the potential PM emission rate is:

The potential PM emissions from the three (3) boilers limited to 0.6 pound PM per million British

thermal units are:

0.010 tons/yr × (2000 lbs/ton / 8760 hrs/yr) = 0.002 lbs/hr

(0.002 lbs/hr / 1.24 MMBtu/hr) = 0.002 lbs PM per MMBtu

Therefore, the three (3) boilers will comply with this rule.

326 IAC 6-3-2 (Process Operations)

(a) The particulate matter (PM) from each of the two (2) EDT machines shall be limited to less

than 19.2 pounds per hour, each, when operating of a process weight rate of 20,000

pounds per hour, each. Since the potentials to emit PM before controls are 1.71 pounds

per hour, each, the two (2) EDT machines will comply with this rule.

(b) The particulate matter (PM) from each of the wet finishing surface grinder shall be limited

to less than 19.2 pounds per hour when operating of a process weight rate of 20,000

pounds per hour. Since the potential to emit PM before controls is 0.00017 pounds per

hour, the surface grinder will comply with this rule.

The limitations were calculated using the following equation:

Interpolation and extrapolation of the data for the process weight rate up to sixty thousand (60,000)

pounds per hour shall be accomplished by use of the equation:

E = 4.10 P 0.67 where E = rate of emission in pounds per hour and 

 P = process weight rate in tons per hour

Air Toxic Emissions

Indiana presently requests applicants to provide information on emissions of the 188 hazardous air

pollutants (HAPs) set out in the Clean Air Act Amendments of 1990. These pollutants are either

carcinogenic or otherwise considered toxic and are commonly used by industries. They are listed

as air toxics on the Office of Air Management (OAM) Construction Permit Application Form Y.

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.

Conclusion

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

attached proposed Minor Source Operating Permit 127-11699-00093.
