Restriction of Particulate Matter to the Ambient Air Beyond the Premises of Origin

Emission Limitation:

No person may cause or allow to occur any handling, transporting or storing of any material; 

construction, repair, cleaning or demolition of a building or its appurtenances; construction 

or use of a road, driveway or open area; or operation of a commercial or industrial installation 

without applying reasonable measures as may be required to prevent, or in a manner which 

allows or may allow, fugitive particulate matter to go beyond the premises of origin in 

quantities that the particulate matter:

Remains visible in the ambient air beyond the property line of origin; or

May be found on surfaces beyond the property line of origin. 

The nature or origin of the particulate matter shall be determined by microscopy or other 

technique proven to be equally accurate and approved by the Director.

Monitoring:

The permittee shall conduct inspections of its installation sufficient to determine compliance 

with this regulation. The source representative would maintain a log noting 1) whether any 

air emissions (except for water vapor) remain visible in the ambient air beyond the property 

line of origin; and 2) whether the visible emissions were normal for the installation. If no 

visible or other significant emissions are observed, then no further observations would be 

required. If a violation of this regulation is discovered, the source representative would 

indicate the cause of the abnormal emissions and any corrective action(s) taken. The source 

representative will also indicate the total duration of any visible emission incident as part of 

the log described above. 

Weekly observations shall be conducted for a minimum of eight (8) consecutive weeks. 

Should no violations of this regulation be observed in that time period, then periodic 

observations shall be conducted every other week for a period of two (2) calendar months. 

Should no violations be observed in this time period, then periodic observations need be done 

no more often than once per month. Should violations be observed, then:

The frequency of periodic monitoring will revert to weekly, though the frequency of 

monitoring would follow the reduction in frequency of monitoring as just outlined, 

provided no further violations were observed.

The permittee will take whatever steps are necessary to bring the installation back in to 

compliance with this regulation. These measures will be implemented as soon as is 

practicable.

Monitoring:

The permittee shall conduct opacity measurements on these emission units using 

USEPA Test Method 22. Opacity measurements must be performed on individual 

emission units, or, for a group of emission units that discharge to a common control 

device, a measurement at the control device is sufficient for the entire group of emission 

units. Readings are only required when the emission unit is operating and when the 

weather conditions allow. If no visible or other significant emissions are observed by a 

Method 22 reading, then no further observations would be required. For emission units 

with visible emissions perceived or believed to exceed the applicable opacity standard, 

the source representative would then conduct a Method 9 observation.

The following monitoring schedule must be maintained:

1. Weekly observations shall be conducted for a minimum of eight (8) consecutive weeks 

after permit issuance. Should no violation of this regulation be observed during this 

period then2. Observations must be made once every two weeks for a period of eight (8) weeks. If a 

violation is noted, monitoring reverts to weekly. Should no violation of this 

regulation be observed during this period then3. Observations must be made once per month. If a violation is noted, monitoring 

reverts to weekly.

If the source reverts to weekly monitoring at any time, monitoring frequency will 

progress in an identical manner from the initial monitoring frequency.

The permittee shall conduct an annual opacity measurement on the emission unit by 

USEPA Test Method 9 with a certified Method 9 observer.

Emergency Provisions

10 CSR 10-6.065(6)(C)7.

I) An emergency or upset as defined in 10 CSR 10-6.065(6)(C)7. shall constitute an 

affirmative defense to an enforcement action brought for noncompliance with 

technology-based emissions limitations. To establish an emergency- or upset-based 

defense, you must demonstrate, through properly signed, contemporaneous 

operating logs or other relevant evidence, the following:

A) That an emergency or upset occurred and that you can identify the source of the 

emergency or upset,

B) That the installation was being operated properly,

C) That you took all reasonable steps to minimize emissions that exceeded 

technology-based emissions limitations or requirements in this permit, and

D) That you submitted notice of the emergency to the Air Pollution Control Program 

within two (2) working days of the time when emission limitations were exceeded 

due to the emergency. This notice must contain a description of the emergency, 

any steps taken to mitigate emissions, and any corrective actions taken.

II) Be aware that an emergency or upset shall not include noncompliance caused by 

improperly designed equipment, lack of preventative maintenance, careless or 

improper operation, or operator error.

Operational Flexibility

10 CSR 10-6.065(6)(C)8.

An installation that has been issued a Part 70 operating permit is not required to apply 

for or obtain a permit revision in order to make any of the changes to the permitted 

installation described below if the changes are not Title I modifications, the changes do 

not cause emissions to exceed emissions allowable under the permit, and the changes 

do not result in the emission of any air contaminant not previously emitted. The 

permittee shall notify the Air Pollution Control Program and the Administrator at least 

seven (7) days in advance of these changes, except as allowed for emergency or upset 

conditions. Emissions allowable under the permit means a federally enforceable 

permit term or condition determined at issuance to be required by an applicable 

requirement that established an emissions limit (including a work practice standard) 

or a federally enforceable emissions cap that the source has assumed to avoid an 

applicable requirement to which the source would otherwise be subject. 

I) Section 502(b)(10) changes. Changes that, under section 502(b)(10) of the Act, 

contravene an express permit term may be made without a permit revision, except 

for changes that would violate applicable requirements of the Act or contravene 

federally enforceable monitoring (including test methods), record keeping, reporting 

or compliance requirements of the permit.

A) Before making a change under this provision, The permittee shall provide 

advance written notice to the Air Pollution Control Program and to the 

Administrator, describing the changes to be made, the date on which the change 
Noranda Aluminum, Inc. 20

Project No. 143-0008-020

will occur, and any changes in emission and any permit terms and conditions 

that are affected. The permittee shall maintain a copy of the notice with the 

permit, and this agency shall place a copy with the permit in the public file. 

Written notice shall be provided to the administrator and this agency at least 

seven (7) days before the change is to be made. If less than seven (7) days notice 

is provided because of a need to respond more quickly to these unanticipated 

conditions, the permittee shall provide notice to the administrator and the 

permitting authority as soon as possible after learning of the need to make the 

change. 

B) The permit shield shall not apply to these changes. 

Off-Permit Changes

10 CSR 10-6.065(6)(C)9.

I) Except as noted below, The permittee may make any change in its permitted 

operations, activities or emissions that is not addressed in, constrained by or 

prohibited by this permit without obtaining a permit revision. Insignificant 

activities listed in the application, but not otherwise addressed in or prohibited by 

this permit, shall not be considered to be constrained by this permit for purposes of 

the off-permit provisions of this section. Off-permit changes shall be subject to the 

following requirements and restrictions:

A) The change must meet all applicable requirements of the Act and may not violate 

any existing permit term or condition; The permittee may not change a permitted 

installation without a permit revision, if this change is subject to any 

requirements under Title IV of the Act or is a Title I modification;

B) The permittee must provide written notice of the change to the permitting 

authority and to the administrator no later than the next annual emissions 

report. This notice shall not be required for changes that are insignificant 

activities under paragraph (6)(B)3. of this rule. This written notice shall describe 

each change, including the date, any change in emissions, pollutants emitted 

and any applicable requirement that would apply as a result of the change.

C) The permittee shall keep a record describing all changes made at the installation 

that result in emissions of a regulated air pollutant subject to an applicable 

requirement and the emissions resulting from these changes; and 

D) The permit shield shall not apply to these changes.

Responsible Official

10 CSR 10-6.020(2)(R)12.

The application utilized in the preparation of this was signed by Stephen J. Heddle, 

President of Primary Products. If this person terminates employment, or is reassigned 

different duties such that a different person becomes the responsible person to 

represent and bind the installation in environmental permitting affairs, the owner or 

operator of this air contaminant source shall notify the Director of the Air Pollution 

Control Program of the change. Said notification shall be in writing and shall be 

submitted within 30 days of the change. The notification shall include the name and 

title of the new person assigned by the source owner or operator to represent and bind 
Noranda Aluminum, Inc. 21

Project No. 143-0008-020

the installation in environmental permitting affairs. All representations, agreement to 

terms and conditions and covenants made by the former responsible person that were 

used in the establishment of limiting permit conditions on this permit will continue to 

be binding on the installation until such time that a revision to this permit is obtained 

that would change said representations, agreements and covenants.

STATEMENT OF BASIS

Permit Reference Documents

These documents were relied upon in the preparation of the operating permit. Because 

they are not incorporated by reference, they are not an official part of the operating 

permit.

1) Part 70 Operating Permit Application, received May 13, 1997; revised 1999

2) Emissions Inventory Questionnaire, received April 1, 1998

3) U.S. EPA document AP-42, Compilation of Air Pollutant Emission Factors; Volume 

I, Stationary Point and Area Sources, Fifth Edition.

Applicable Requirements Included in the Operating Permit but Not in the 

Application

In the operating permit application, the installation indicated they were not subject to 

the following regulation(s). However, in the review of the application, the agency has 

determined that the installation is subject to the following regulation(s) for the reasons 

stated.

10 CSR 10-6.180, Measurement of Emissions of Air Contaminants, 

This rule has been included in the operating permit in order to provide citing for 

the allowance of requests for emissions data results. On past forms issued by

the Air Pollution Control Program, including the application for this permit, it 

was automatically marked as an administrative rule not required to be listed as 

an applicable requirement. It is no longer judged to be solely administrative and 

is, therefore, included in the operating permit.

Other Air Regulations Determined Not to Apply to the Operating Permit

None

Construction Permit Revisions

No revisions

NSPS Applicability

It has been determined that the New Source Performance Standards for steam 

generating units (40 CFR Part 60 Subparts Da, Db and/or Dc) are not applicable to 

any of the steam generating units addressed in this permit (EU3730, EU3740, 

EU3750, EU4900, EU4910, EU4920) because of size as shown in the following table.

Noranda Aluminum, Inc. SB - 2

Project No. 143-0008-020

It has been determined that the New Source Performance Standards for Primary 

Aluminum Reduction Plants (40 CFR Part 60 Subpart S) is not applicable to any of the 

units addressed in this permit because this standard is only applicable to potroom 

groups and anode bake plants. None of the equipment addressed in this permit is part 

of a potroom group or an anode bake plant.

MACT Applicability

It has been determined that the National Emission Standards for Hazardous Air 

Pollutants from primary aluminum reduction plants and from secondary aluminum 

production are not applicable to any of the units addressed in this permit because of 

the following reasons.

40 CFR Part 63 Subpart LL is not applicable to any of the emission units addressed in 

this permit because boilers, furnaces and raw material unloading equipment are not 

affected units. Affected units are potlines, paste production plants, and anode bake 

furnaces.

40 CFR Part 63 Subpart RRR is not applicable to any of the units addressed in this 

permit because boilers, raw material unloading equipment and homogenizing furnaces 

are not affected units. The furnaces are not affected units because they are not 

involved in melting, holding, refining, fluxing, or alloying. The homogenizing furnaces 

just take final product (ingot) and heat without melting.

Other Regulatory Determinations

The installation will be divided into segments for operating permit purposes, with each 

segment receiving a separate operating permit. This permit will be for the boilers and 

for the furnaces that will not be affected by the National Emission Standards for 

Hazardous Air Pollutants (Subparts LL and/or RRR) and for the river unloading and

railcar unloading. 

10 CSR 10-6.090 is not applicable to any of the emission units addressed in this 

permit because the rule only applies to potroom groups and anode bake plants. None 

of the units addressed in this permit are part of a potroom group or anode bake plant.

10 CSR 10-3.050 was listed as applicable to emission units EU3730, EU3740, 

EU3750, EU4900, EU4910, and EU4920 in the supplemental information submitted 

by Noranda. It has been determined that this regulation is not applicable to these 

emission points because indirect heating units are exempt. These emission units are 

considered indirect heating units because fuel is burned for the primary purpose of 

producing steam, hot water or hot air and in the course of doing so, the products of 

combustion do not come into direct contact with the process materials.

10 CSR 10-3.060 is not applicable to emission units EU3730, EU3740, EU4900 and 

EU4920 because they are considered existing units (installed prior to April 3, 1971) 

with a heat input capacity of ten (10) million BTU per hour or less.
Noranda Aluminum, Inc. SB - 3

Project No. 143-0008-020

The following assumptions were made in the review of the application and preparation 

of this document.

1. It was assumed that the process weight rate for emission units EU3760, EU4790, 

EU4800 and EU4810 was equal to one ton per hour. This was a conservative 

assumption and gave 4.1 pounds/hour of allowable particulate matter emissions. 

2. It was assumed that emission units EU4790 (year – 1971) and EU4800 (year –

1971) meet the definition of new sources under state regulation 10 CSR 10-3.080 

and are, therefore, subject to the more restrictive 20% opacity limit instead of the 

40% opacity for existing sources. This conservative assumption was made because 

the month was not indicated in any of the application documents. The 

applicability date for “new” versus “existing” for this regulation is April 3, 1971.

3. It was assumed that emission units EU4790 (year – 1971) and EU4800 (year –

1971) meet the definition of new source under state regulation 10 CSR 10-6.260 

and are, therefore, subject to the more restrictive 500 ppm sulfur dioxide limit 

instead of the 2000 ppm sulfur dioxide limit for existing sources. This conservative 

assumption was made because the month was not indicated in any of the 

application documents. The applicability date for “new” versus “existing” for this 

regulation is February 24, 1971.

4. A flow rate of at least 10 cubic feet/second was assumed for the aluminum holding 

furnace (EU3760). The flow rate was not given in the emissions inventory 

questionnaire so this conservative estimate of flow rate was made based on the flow 

rates given for the other similar equipment in the emissions inventory 

questionnaire.

5. It was assumed that emission units EU4790, EU4800, and/or EU4810 were not 

modified or reconstructed after June 9, 1989, and therefore, New Source 

Performance Standards for Small Industrial-Commercial-Institutional Steam 

Generating Units (NSPS Subpart Dc) would not be applicable. This assumption 

was made based on the fact that the application indicated that NSPS Subpart Dc 

was not applicable.

6. Because of the negligible sulfur content of natural gas and propane it was assumed 

that the units covered by this permit do no cause or contribute to concentrations of 

sulfur compounds in the ambient air that exceed those specified in 10 CSR 10-

6.010. Noranda has provided documents indicating that only low sulfur natural

Other Regulations Not Cited in the Operating Permit or the Above Statement of 

Basis

Any regulation which is not specifically listed in either the Operating Permit or in the 

above Statement of Basis does not appear, based on this review, to be an applicable 

requirement for this installation for one (1) or more of the following reasons: 

1. The specific pollutant regulated by that rule is not emitted by the installation;

2. The installation is not in the source category regulated by that rule; 

3. The installation is not in the county or specific area that is regulated under the 

authority of that rule; 

4. The installation does not contain the type of emission unit which is regulated by 

that rule;

5. The rule is only for administrative purposes.

Should a later determination conclude that the installation is subject to one (1) or 

more of the regulations cited in this Statement of Basis or other regulations which 

were not cited, the installation shall determine and demonstrate, to the APCP's 

satisfaction, the installation's compliance with that regulation(s). If the installation is 

not in compliance with a regulation, which was not previously cited, the installation 

shall submit to the APCP a schedule for achieving compliance for that regulation(s).
