Occupational Safety and Health Administration (OSHA) plans, or other existing plans

such as the PMP required in Condition D.1.5, as the OMP, provided the alternative plans

meet the above listed criteria in Condition D.1.6(a).

(c) If the OMP fails to address or inadequately addresses an event that meets the

characteristics of a malfunction or period of excess emissions at the time the plan is

initially developed, the Permittee shall revise the OMP within forty-five (45) days after

such an event occurs. The revised plan shall include procedures for operating and

maintaining tanks (CH1, CH2, CH3, CH4, CH5 and CH6), the air pollution control

device, the add-on air pollution control device and the monitoring equipment, during

similar malfunction or period of excess emissions events, and a program for corrective

action for such events.

(d) If actions taken by the Permittee during periods of malfunction or period of excess

emissions are inconsistent with the procedures specified in the OMP, the Permittee shall

record the actions taken for that event and shall report by phone such actions within two

(2) working days after commencing actions inconsistent with the plan. This report shall

be followed by a letter within seven (7) working days after the end of the event, unless

the Permittee makes alternative reporting arrangements, in advance, with IDEM, OAQ.

(e) The Permittee shall keep the written OMP on record after it is developed to be made

available, upon request, by IDEM, OAQ for the life of tanks (CH1, CH2, CH3, CH4, CH5

and CH6) or until the tank is no longer subject to the provisions of 40 CFR 63.340. In

addition, if the OMP is revised, the Permittee shall keep previous versions of the OMPs

on record to be made available for inspection, upon request by IDEM, OAQ for a period

of five (5) years after each revision to the plan.

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 source in Indiana is less than (10) tons per

year and Biddle Precision Components, Inc. is a much smaller source in comparison. So no

calculations were necessary for this source because the emissions from this source will be less

than ten (10) tons per year.

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.” 

Pollutant Potential To Emit (tons/year)

PM 0.00

PM-10 0.00

SO2 0.00

VOC 0.00

CO 0.00

NOx 0.00

HAP’s Potential To Emit (tons/year)

Nickel Compounds Less Than 10

Chromium Compounds Less Than 10

 TOTAL Less Than 25

(a) 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.

(b) This new source is subject to 326 IAC 20-8 but not subject to 326 IAC 2-5.5-1 (b)(2)

(registration) because the source consists of only hard chromium (not decorative

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

statement (a) above). Therefore, the source is subject to the provisions of 326 IAC 2-

6.1-3(a).

Actual Emissions

Permit Reviewer: Phillip Ritz/EVP

On May 11, 2000, the Office of Air Quality (OAQ) had a notice published in the Daily Ledger in

Noblesville, Indiana, stating that Biddle Precision Components, Inc. had applied for a construction permit

to construct and operate a hard chromium electroplating operation coating steel with control. The notice

also stated that OAQ 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.

Upon further review, the OAQ has decided to make the following revisions to the permit to

incorporate updated language for new hard chromium electroplating operations (bolded language has

been added, the language with a line through it has been deleted). The Table Of Contents has been

modified to reflect these changes.

The OAQ has revised the permit to replace the old name of Office of Air Management (OAM) with the

new name of the Office of Air Quality (OAQ).

(a ) Conditions D.1.1 through D.1.4 in the permit section entitled “Emission Limitations and

Standards” have been revised as shown below to: (1)reflect the use of the term “emissions unit”

in revised state permitting rules; (2) be more consistent with the language of the Chromium

Electroplating NESHAP; (3) delete language that was inadvertently included in the draft permit;

and (4) add the requirement to address excess emissions as well as malfunctions if they occur.

By this permit, the Permittee is approved to use a composite mesh-pad system as the emission

reduction technique to comply with the Chromium Electroplating NESHAP. However, IDEM,

OAQ encourages the Permittee to also consider the use of fume suppressants to comply as this

technique can achieve a greater degree of emission reductions. Use of fume suppressants can

be approved in a permit modification as an alternative means of compliance in addition to or

instead of the composite mesh-pad system.

Emission Limitations and Standards [326 IAC 2-6.1-5(1)]

D.1.1 General Provisions Relating to HAPs [326 IAC 20-1-1][40 CFR Part 63, Subpart A]

CH6). A copy of this rule is attached. The permittee shall comply with the requirements of

this condition on and after the compliance date for the tanks.
D.1.3 Chromium Emissions Limitation [40 CFR 63.342(c)] [40 CFR 63.343(a)(1)&(2)]

(a) The emission limitations in this condition apply only during tank operation, and also

apply during periods of startup and shutdown as these are routine occurrences for tanks

subject to 326 IAC 20-8-1. The emission limitations do not apply during periods of

malfunction. 

(b) During tank operation, the Permittee shall control chromium emissions discharged to the

atmosphere from tanks (CH1, CH2, CH3, CH4, CH5 and CH6) by:

(1) Not allowing the concentration of total chromium in the exhaust gas stream

discharged to the atmosphere to exceed one-hundredth milligrams of total

chromium per dry standard cubic meter of ventilation air (0.01 mg/dscm)

[equivalent to four and four-tenths times ten raised to the power of negative six

grains of total chromium per dry standard cubic foot of ventilation air (4.4x10-6

gr/dscf)].

(b) The hard chromium electroplating tanks, identified as tanks (CH1, CH2, CH3, CH4,

CH5 and CH6) above, are considered a large, existing hard chromium

electroplating operation. During tank operation, the Permittee shall control

chromium emissions discharged to the atmosphere from the tank(s) by not

allowing the concentration of total chromium in the exhaust gas stream

discharged to the atmosphere to exceed 0.015 mg/dscm [6.6x10-6 gr/dscf]. 

D.1.4 Work Practice Standards [40 CFR 63.342(f)]

The following work practice standards apply to tanks (CH1, CH2, CH3, CH4, CH5 and CH6):

(a) At all times, including periods of startup, shutdown, malfunction and excess emissions,

the Permittee shall operate and maintain tanks (CH1, CH2, CH3, CH4, CH5 and CH6),

including the air pollution control techniques (composite mesh pad scrubber) and

monitoring equipment, in a manner consistent with good air pollution control practices,

consistent with the Operation and Maintenance Plan (OMP) required by Condition D.1.6.

(a) Malfunctions and excess emissions shall be corrected as soon as practicable after their

occurrence in accordance with the OMP required by Condition D.1.6.

(b) These operation and maintenance requirements are enforceable independent of

emissions limitations or other requirements in this section.

(c) Determination of whether acceptable operation and maintenance procedures are being

used will be based on information available to IDEM, OAQ, which may include, but is not

limited to, monitoring results; review of the OMP, procedures, and records; and

inspection of the source.

(d) Based on the results of a determination made under paragraph (d) of this condition,

IDEM, OAQ may require that the Permittee make changes to the OMP required by

Condition D.1.6. Revisions may be required if IDEM, OAQ finds that the plan:

(1) Does not address a malfunction or period of excess emissions that has

occurred;

(2) Fails to provide for the operation of tanks (CH1, CH2, CH3, CH4, CH5 and

CH6), the air pollution control techniques (composite mesh pad scrubber), and

process monitoring equipment during a malfunction or period of excess

emissions in a manner consistent with good air pollution control practices; or
(3) Does not provide adequate procedures for correcting malfunctioning process

equipment, air pollution control techniques (composite mesh pad scrubber),
