County. The company is an existing primary aluminum reduction installation with existing 

secondary aluminum production operations. Aluminum originates as an oxide called alumina. 

Alumina (Al2O3) is received at the plant and undergoes electrolytic reduction, known as the 

Hall-Heroult process, to produce aluminum. The electrolytic reduction takes place in shallow 

carbon-lined steel shells called pots. The secondary aluminum operations include aluminum 

alloying, casting and auxiliary operations.

I. Installation Description and Equipment Listing

INSTALLATION DESCRIPTION

Noranda Aluminum, Inc. operates a primary aluminum refining operation in New Madrid County. The 

company is an existing primary aluminum reduction installation but is also involved in secondary 

aluminum production. 

Alumina (Al2O3) is received at the plant and undergoes electrolytic reduction, known as the HallHeroult process, to obtain aluminum. The electrolytic reduction takes place in shallow carbon-lined 

steel shells called pots. The anodes are carbon electrodes extending into the pot, and the cathode is the 

carbon lining within the pot. 

In the reduction of alumina, carbon, in the form of an anode, is negatively charged to react with the 

alumina. The carbon anode, also called green anode, is continuously depleted until a remnant or ―butt‖ 

remains. These anodes are prepared with petroleum coke mixed with pitch binder to make a paste. The 

coke is crushed, ground, and screened before being mixed with the pitch binder. The paste is added 

directly to the anode casings and baked in a pre-bake furnace. This type of aluminum reduction cell is 

most common because it is more efficient electrically and it emits fewer organic compounds than other 

forms of reduction cells. 

The electrolyte is molten cryolite (Na3AlF6) which also serves as the solvent for alumina. The 

electrolytic reduction of alumina by the carbon from the electrode forms elemental aluminum and 

carbon dioxide (CO2). The aluminum is deposited around the carbon-lined steel shell, where it remains 

as a molten metal below the surface of the cryolitic bath. Using a vacuum siphon, the aluminum is 

removed from the pots every 24 to 48 hours and transferred to a reverberatory holding furnace. From 

there, it is either cast or transported to the holding facilities.

Noranda Aluminum, Inc. is considered a major source under construction and operating permits. Four 

separate initial Part 70 Operating Permits were issued to Noranda Aluminum, Inc. for the entire 

installation. A single P70 renewal permit is being issued consolidating all four initial permits. 

The reported actual emissions for the past five years for the installation are listed below:

Permit Condition PW003

10 CSR 10-6.220 Restriction of Emission of Visible Air Contaminants

Emission Limitation:

1) No owner or other person shall cause or permit emissions to be discharged into the atmosphere from 

any existing1source any visible emissions with an opacity greater than 40%. 

2) No owner or other person shall cause or permit emissions to be discharged into the atmosphere from 

any new

2

source any visible emissions with an opacity greater than 20%.

3) Exception:

A person may discharge into the atmosphere from any source of emissions for a period(s) 

aggregating not more than six (6) minutes in any 60 minutes air contaminants with an opacity up to 

60%. 

Monitoring:

1) The permittee shall conduct opacity readings on the emission unit(s) using the procedures contained 

in USEPA Test Method 22. At a minimum, the observer should be trained and knowledgeable about 

the effects on visibility of emissions caused by background contrast, ambient lighting, observer 

position relative to lighting, wind and the presence of uncombined water. Readings are only 

required when the emission unit(s) is operating and when the weather conditions allow. If no visible 

or other significant emissions are observed using these procedures, 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.

2) The following monitoring schedule must be maintained:

a) Observations must be made once per month. If a violation is noted, then 

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

no violation of this regulation be observed during this period then monitoring reverts to monthly 

monitoring. 

Record keeping:

1) The permittee shall maintain records of all observation results (see Attachment B), noting:

a) Whether any air emissions (except for water vapor) were visible from the emission units,

b) All emission units from which visible emissions occurred, and

c) Whether the visible emissions were normal for the process.

d) The permittee shall maintain records of any equipment malfunctions.

2) The permittee shall maintain records of any other Method 9 test performed in accordance with this 

permit condition. (See Attachment C)

Monitoring:

The Department of Natural Resources, Air Pollution Control Program, Compliance/Enforcement Section 

has approved a Compliance Assurance Monitoring (CAM) Plan provided by the facility. The key 

elements of the monitoring approach, including the indicators to be monitored, indicator ranges, and 

performance criteria are presented in Table 1 of Attachment D. Visible emissions and pressure drop 

across the filter system are selected as the CAM performance indicators for the baghouse. 

1) CAM Compliance Indicators: The following CAM Indicators shall be used to monitor the control 

device (baghouse):

a) Visible Emissions 

i) Visible emissions from the baghouse stack exhaust shall be monitored using EPA Reference 

Method 22-like procedures on a daily basis to ensure no visible emissions during the 

operation of this unit(s). The permittee is only required to take readings when the emission 

unit(s) is operating and when the weather conditions allow. 
Noranda Aluminum, Incorporated Part 70 Operating Permit 29

Installation ID: 143-0008 Project No. 2005-10-032

b) Pressure Drop 

i) The permittee shall check and document the baghouse pressure drop daily. The pressure 

drop across the baghouse shall be maintained within the ranges specified for baghouse CD-4 

in Table 2 of Attachment D.

2) CAM Compliance Indicator Range: An excursion is defined as either the presence of visible 

emissions or as a pressure drop falls out of the normal operating range specified for baghouse CD-4 

in Table 2 of Attachment D. An excursion of either indicator constitutes an excursion. If visible 

emissions are present when the pressure drop is within its specified indicator range and no baghouse 

problems are identified as the cause, the pressure drop indicator range shall be re-evaluated by 

Noranda Aluminum, Inc.. Excursions trigger an inspection, corrective action, and need to be 

reported in the next Semiannual Monitoring Report; if an excursion results in excess emissions 

exceeding one hour, Noranda Aluminum, Inc. may elect to file a startup, shutdown, and malfunction 

assertion under 10 CSR 10-6.050 if appropriate to the situation. 

3) Proper maintenance: At all times, the permittee shall maintain the monitoring, including but not 

limited to, maintaining necessary parts for routine repairs of the monitoring equipment. [§64.7(b)]

4) Continued operation: Except for, as applicable, monitoring malfunctions, associated repairs, and 

required quality assurance or control activities, the permittee shall collect data at all required 

intervals when the emission unit is operating. Data recorded during monitoring malfunctions, 

associated repairs, and required quality assurance or control activities shall not be used for purposes 

of part 64. The permittee shall use all the data collected during all other periods in assessing the 

operation of the control device and associated control system. A monitoring malfunction is any 

sudden, infrequent, not reasonably preventable failure of the monitoring to provide valid data. 

Monitoring failures that are caused in part by poor maintenance or careless operation are not 

malfunctions. [§64.7(c)]

5) Response to exceedances: [§64.7(d)]

a) Upon detecting an exceedance, the permittee shall restore operation of the emission unit 

(including the control device and associated capture system) to its normal or usual manner of 

operation as expeditiously as practicable in accordance with good air pollution control practices 

for minimizing emissions. The response shall include minimizing the period of any startup, 

shutdown or malfunction and taking any necessary corrective actions to restore normal operation 

and prevent the likely recurrence of the cause of an exceedance (other than those caused by 

excused startup or shutdown conditions). Such actions may include initial inspection and 

evaluation, recording that operations returned to normal without operator action (such as through 

response by a computerized distribution control system), or any necessary follow-up actions to 

return operation to within the indicator range, designated condition, or below the applicable 

emission limitation or standard, as applicable. [§64.7(d)(1)]

b) Determination of whether the permittee has used acceptable procedures in response to an 

excursion or exceedance will be based on information available, which may include but is not 

limited to, monitoring results, review of operation and maintenance procedures and records, and 

inspection of the control device, associated capture system, and the process. [§64.7(d)(2)]

Recordkeeping:

1) General Recordkeeping Requirements: 

a) The permittee shall comply with the recordkeeping requirements specified in §70.6(a)(3)(ii). The 

permittee shall maintain records of monitoring data, monitor performance data, corrective 

actions taken, any written quality improvement plan required pursuant to §64.8 and any activities 

undertaken to implement a quality improvement plan, and other supporting information required 
Noranda Aluminum, Incorporated Part 70 Operating Permit 30

Installation ID: 143-0008 Project No. 2005-10-032

to be maintained under part 64 (such as data used to document the adequacy of monitoring, or 

records of monitoring maintenance or corrective actions). [§64.9(b)(1)]

b) Instead of paper records, the permittee may maintain records on alternative media, such as 

microfilm, computer files, magnetic tape disks, or microfiche, provided that the use of such 

alternative media allows for expeditious inspection and review, and does not conflict with other 

applicable recordkeeping requirements. [§64.9(b)(2)]

2) All records shall be maintained for five years. 

3) These records shall be made available immediately for inspection to the Department of Natural 

Resources' personnel upon their verbal request and presentation of identification.

Reporting:

1) General Reporting Requirements: The permittee shall submit semi-annual monitoring certified by a 

responsible official using the semi-annual monitoring report and annual compliance certification to 

the Air Pollution Control Program Enforcement Section, P.O. Box 176, Jefferson City, MO 65102, 

as required by 10 CSR 10-6.065(6)(C)1.C.(III). The report shall include, at a minimum, the 

following information, as applicable: [§64.9(a)(1) & (2)]

a) All instances of deviations from permit requirements must be clearly identified; 

b) Prompt reporting of deviations from permit requirements, including those attributable to upset 

conditions as defined in the permit, the probable cause of such deviations, and any corrective 

actions or preventive measures taken; 

c) Summary information on the number, duration and cause (including unknown cause, if 

applicable) of excursions or exceedances, as applicable, and the corrective actions taken; 

[§64.9(a)(2)(i)]

d) Summary information on the number, duration and cause (including unknown cause, if 

applicable) for monitor downtime incidents (other than downtime associated with zero and span 

or other daily calibration checks, if applicable); and [§64.9(a)(2)(ii)]

e) A description of the actions taken to implement a QIP during the reporting period as specified in 

40 CFR 64.8. Upon completion of a QIP, the permittee shall include in the next summary report 

documentation that the implementation of the plan has been completed and reduced the 

likelihood of similar levels of excursions or exceedances occurring. [§64.9(a)(2)(iii)].

2) Documentation of need for improved monitoring: If the permittee identifies a failure to achieve 

compliance with this permit condition for which the approved monitoring did not provide an 

indication of an exceedance while providing valid data, or the results of compliance or performance 

testing document a need to modify the existing indicator ranges or designated conditions, the 

permittee shall promptly notify the Air Pollution Control Program and, if necessary, submit a 

proposed modification to the part 70 permit to address the necessary monitoring changes. Such a 

modification may include, but is not limited to, reestablishing indicator ranges or designated 

conditions, modifying the frequency of conducting monitoring and collecting data, or the monitoring 

of additional parameters. [§64.7(e)]

3) The permittee shall report to the Air Pollution Control Program, Enforcement Section, P. O. Box 

176, Jefferson City, MO 65102, no later than ten (10) days after any deviations/exceedance of the 

Emission Limitation.

4) Continued operation: Except for, as applicable, monitoring malfunctions, associated repairs, and 

required quality assurance or control activities, the permittee shall collect data at all required 

intervals when the emission unit is operating. Data recorded during monitoring malfunctions, 

associated repairs, and required quality assurance or control activities shall not be used for purposes 

of part 64. The permittee shall use all the data collected during all other periods in assessing the 

operation of the control device and associated control system. A monitoring malfunction is any 

sudden, infrequent, not reasonably preventable failure of the monitoring to provide valid data. 

Monitoring failures that are caused in part by poor maintenance or careless operation are not 

malfunctions. [§64.7(c)]

5) Response to exceedances: [§64.7(d)]

a) Upon detecting an exceedance, the permittee shall restore operation of the emission unit 

(including the control device and associated capture system) to its normal or usual manner of 

operation as expeditiously as practicable in accordance with good air pollution control practices 

for minimizing emissions. The response shall include minimizing the period of any startup, 

shutdown or malfunction and taking any necessary corrective actions to restore normal operation 

and prevent the likely recurrence of the cause of an exceedance (other than those caused by 

excused startup or shutdown conditions). Such actions may include initial inspection and 

evaluation, recording that operations returned to normal without operator action (such as through 

response by a computerized distribution control system), or any necessary follow-up actions to 

return operation to within the indicator range, designated condition, or below the applicable 

emission limitation or standard, as applicable. [§64.7(d)(1)]

b) Determination of whether the permittee has used acceptable procedures in response to an 

excursion or exceedance will be based on information available, which may include but is not 

limited to, monitoring results, review of operation and maintenance procedures and records, and 

inspection of the control device, associated capture system, and the process. [§64.7(d)(2)]

Recordkeeping:

1) General Recordkeeping Requirements: 

a) The permittee shall comply with the recordkeeping requirements specified in §70.6(a)(3)(ii). The 

permittee shall maintain records of monitoring data, monitor performance data, corrective 

actions taken, any written quality improvement plan required pursuant to §64.8 and any activities 

undertaken to implement a quality improvement plan, and other supporting information required 

to be maintained under part 64 (such as data used to document the adequacy of monitoring, or 

records of monitoring maintenance or corrective actions). [§64.9(b)(1)]

b) Instead of paper records, the permittee may maintain records on alternative media, such as 

microfilm, computer files, magnetic tape disks, or microfiche, provided that the use of such 

alternative media allows for expeditious inspection and review, and does not conflict with other 

applicable recordkeeping requirements. [§64.9(b)(2)]

2) All records shall be maintained for five years. 

3) These records shall be made available immediately for inspection to the Department of Natural 

Resources' personnel upon their verbal request and presentation of identification.

2) The permittee shall not emit particulate matter (PM) in excess of the 58.51 from EU0440 through 

EU0460 and EU0480 through EU0590.

Note: The emission rates in this permit condition apply to the sources individually and not the 

aggregated sources.

3) No person shall cause, allow or permit the emission of particulate matter from any source in a 

concentration in excess of 0.30 grain per standard cubic foot of exhaust gases.

Monitoring:

The Department of Natural Resources, Air Pollution Control Program, Compliance/Enforcement Section 

has approved a Compliance Assurance Monitoring (CAM) Plan provided by the facility. The key 

elements of the monitoring approach, including the indicators to be monitored, indicator ranges, and 

performance criteria are presented in Table 1 of Attachment D. Visible emissions and pressure drop 

across the filter system are selected as the CAM performance indicators for the baghouse. 

1) CAM Compliance Indicators: The following CAM Indicators shall be used to monitor the control 

device (baghouse):

a) Visible Emissions 

i) Visible emissions from the baghouse stack exhaust shall be monitored using EPA Reference 

Method 22-like procedures on a daily basis to ensure no visible emissions during the 

operation of this unit(s). The permittee is only required to take readings when the emission 

unit(s) is operating and when the weather conditions allow. 

b) Pressure Drop 

i) The permittee shall check and document the baghouse pressure drop daily. The pressure 

drop across the baghouse shall be maintained within the ranges specified for baghouse CD-8 

in Table 2 of Attachment D.

2) CAM Compliance Indicator Range: An excursion is defined as either the presence of visible 

emissions or as a pressure drop falls outside of the normal operating range specified for baghouse 

CD-8 in Table 2 of Attachment D. An excursion of either indicator constitutes an excursion. If 

visible emissions are present when the pressure drop is within its specified indicator range and no 
Noranda Aluminum, Incorporated Part 70 Operating Permit 39

Installation ID: 143-0008 Project No. 2005-10-032

baghouse problems are identified as the cause, the pressure drop indicator range shall be reevaluated by Noranda Aluminum, Inc.. Excursions trigger an inspection, corrective action, and need 

to be reported in the next Semiannual Monitoring Report; if an excursion results in excess emissions 

exceeding one hour, Noranda Aluminum, Inc. may elect to file a startup, shutdown, and malfunction 

assertion under 10 CSR 10-6.050 if appropriate to the situation. 

3) Proper maintenance: At all times, the permittee shall maintain the monitoring, including but not 

limited to, maintaining necessary parts for routine repairs of the monitoring equipment. [§64.7(b)]

4) Continued operation: Except for, as applicable, monitoring malfunctions, associated repairs, and 

required quality assurance or control activities, the permittee shall collect data at all required 

intervals when the emission unit is operating. Data recorded during monitoring malfunctions, 

associated repairs, and required quality assurance or control activities shall not be used for purposes 

of part 64. The permittee shall use all the data collected during all other periods in assessing the 

operation of the control device and associated control system. A monitoring malfunction is any 

sudden, infrequent, not reasonably preventable failure of the monitoring to provide valid data. 

Monitoring failures that are caused in part by poor maintenance or careless operation are not 

malfunctions. [§64.7(c)]

5) Response to exceedances: [§64.7(d)]

a) Upon detecting an exceedance, the permittee shall restore operation of the emission unit 

(including the control device and associated capture system) to its normal or usual manner of 

operation as expeditiously as practicable in accordance with good air pollution control practices 

for minimizing emissions. The response shall include minimizing the period of any startup,

evaluation, recording that operations returned to normal without operator action (such as through 

response by a computerized distribution control system), or any necessary follow-up actions to 

return operation to within the indicator range, designated condition, or below the applicable 

emission limitation or standard, as applicable. [§64.7(d)(1)]

b) Determination of whether the permittee has used acceptable procedures in response to an 

excursion or exceedance will be based on information available, which may include but is not 

limited to, monitoring results, review of operation and maintenance procedures and records, and 

inspection of the control device, associated capture system, and the process. [§64.7(d)(2)]

Recordkeeping:

1) General Recordkeeping Requirements: 

a) The permittee shall comply with the recordkeeping requirements specified in §70.6(a)(3)(ii). The 

permittee shall maintain records of monitoring data, monitor performance data, corrective 

actions taken, any written quality improvement plan required pursuant to §64.8 and any activities 

undertaken to implement a quality improvement plan, and other supporting information required

Emission Limitation:

1) Noranda Aluminum, Inc. shall not discharge PM10 into the atmosphere from EP-12 (EU0790 

through EU0810) and EP-13 (EU0820 through EU0880) stacks in excess of 0.5314 lb/hr and 0.8113 

lb/hr, respectively. The emission rates shall be verified through compliance testing, as detailed in 

Special Condition 6 of Construction Permit 102004-001. 

[PSD Permit 102004-001, Special Condition 2]

2) The permittee shall not emit particulate matter (PM) in excess of 58.51 lbs/hr EU0790 through 

EU0880.

Note: The emission rates in this permit condition apply to the sources individually and not the 

aggregated sources.

3) No person shall cause, allow or permit the emission of particulate matter from any source in a 

concentration in excess of 0.30 grain per standard cubic foot of exhaust gases.

Monitoring:

The Department of Natural Resources, Air Pollution Control Program, Compliance/Enforcement Section 

has approved a Compliance Assurance Monitoring (CAM) Plan provided by the facility. The key 

elements of the monitoring approach, including the indicators to be monitored, indicator ranges, and 

performance criteria are presented in Table 1 of Attachment D. Visible emissions and pressure drop 

across the filter system are selected as the CAM performance indicators for the baghouse. 

1) CAM Compliance Indicators: The following CAM Indicators shall be used to monitor the control 

device (baghouse):

a) Visible Emissions 

i) Visible emissions from the baghouse stack exhaust shall be monitored using EPA Reference 

Method 22-like procedures on a daily basis to ensure no visible emissions during the 

operation of this unit(s). The permittee is only required to take readings when the emission 

unit(s) is operating and when the weather conditions allow. 
Noranda Aluminum, Incorporated Part 70 Operating Permit 48

Installation ID: 143-0008 Project No. 2005-10-032

b) Pressure Drop 

i) The permittee shall check and document the baghouse pressure drop daily. The pressure 

drop across the baghouse shall be maintained within the ranges specified for baghouses CD12 and CD-13 in Table 2 of Attachment D.

2) CAM Compliance Indicator Range: An excursion is defined as either the presence of visible 

emissions or as a pressure drop falls outside of the normal operating range specified for baghouses 

CD-12 and CD-13 in Table 2 of Attachment D. An excursion of either indicator constitutes an 

excursion. If visible emissions are present when the pressure drop is within its specified indicator 

range and no baghouse problems are identified as the cause, the pressure drop indicator range shall 

be re-evaluated by Noranda Aluminum, Inc.. Excursions trigger an inspection, corrective action, and 

need to be reported in the next Semiannual Monitoring Report; if an excursion results in excess 

emissions exceeding one hour, Noranda Aluminum, Inc. may elect to file a startup, shutdown, and 

malfunction assertion under 10 CSR 10-6.050 if appropriate to the situation. 

3) Proper maintenance: At all times, the permittee shall maintain the monitoring, including but not 

limited to, maintaining necessary parts for routine repairs of the monitoring equipment. [§64.7(b)]

4) Continued operation: Except for, as applicable, monitoring malfunctions, associated repairs, and 

required quality assurance or control activities, the permittee shall collect data at all required 

intervals when the emission unit is operating. Data recorded during monitoring malfunctions, 

associated repairs, and required quality assurance or control activities shall not be used for purposes 

of part 64. The permittee shall use all the data collected during all other periods in assessing the 

operation of the control device and associated control system. A monitoring malfunction is any 

sudden, infrequent, not reasonably preventable failure of the monitoring to provide valid data. 

Monitoring failures that are caused in part by poor maintenance or careless operation are not 

malfunctions. [§64.7(c)]

5) Response to exceedances: [§64.7(d)]

a) Upon detecting an exceedance, the permittee shall restore operation of the emission unit 

(including the control device and associated capture system) to its normal or usual manner of 

operation as expeditiously as practicable in accordance with good air pollution control practices 

for minimizing emissions. The response shall include minimizing the period of any startup, 

shutdown or malfunction and taking any necessary corrective actions to restore normal operation 

and prevent the likely recurrence of the cause of an exceedance (other than those caused by 

excused startup or shutdown conditions). Such actions may include initial inspection and 

evaluation, recording that operations returned to normal without operator action (such as through 

response by a computerized distribution control system), or any necessary follow-up actions to 

return operation to within the indicator range, designated condition, or below the applicable 

emission limitation or standard, as applicable. [§64.7(d)(1)]

b) Determination of whether the permittee has used acceptable procedures in response to an 

excursion or exceedance will be based on information available, which may include but is not 

limited to, monitoring results, review of operation and maintenance procedures and records, and 

inspection of the control device, associated capture system, and the process. [§64.7(d)(2)]

Recordkeeping:

2) The permittee shall not emit particulate matter (PM) in excess of 51.28 lbs/hr EU1220 through 

EU1280 and EU1300.

Note: The emission rates in this permit condition apply to the sources individually and not the 

aggregated sources.

3) No person shall cause, allow or permit the emission of particulate matter from any source in a 

concentration in excess of 0.30 grain per standard cubic foot of exhaust gases.

Monitoring:

The Department of Natural Resources, Air Pollution Control Program, Compliance/Enforcement Section 

has approved a Compliance Assurance Monitoring (CAM) Plan provided by the facility. The key 

elements of the monitoring approach, including the indicators to be monitored, indicator ranges, and 

performance criteria are presented in Table 1 of Attachment D. Visible emissions and pressure drop 

across the filter system are selected as the CAM performance indicators for the baghouse. 

1) CAM Compliance Indicators: The following CAM Indicators shall be used to monitor the control 

device (baghouse):

a) Visible Emissions 

i) Visible emissions from the baghouse stack exhaust shall be monitored using EPA Reference 

Method 22-like procedures on a daily basis to ensure no visible emissions during the 

operation of this unit(s). The permittee is only required to take readings when the emission 

unit(s) is operating and when the weather conditions allow. 

b) Pressure Drop 

i) The permittee shall check and document the baghouse pressure drop daily. The pressure 

drop across the baghouse shall be maintained within the ranges specified for baghouses CD23 and CD-24 in Table 2 of Attachment D.

2) CAM Compliance Indicator Range: An excursion is defined as either the presence of visible 

emissions or as a pressure drop falls outside of the normal operating range specified for baghouses 

CD-23 and CD-24 in Table 2 of Attachment D. An excursion of either indicator constitutes an 

excursion. If visible emissions are present when the pressure drop is within its specified indicator 

range and no baghouse problems are identified as the cause, the pressure drop indicator range shall 

be re-evaluated by Noranda Aluminum, Inc.. Excursions trigger an inspection, corrective action, and 

need to be reported in the next Semiannual Monitoring Report; if an excursion results in excess 

emissions exceeding one hour, Noranda Aluminum, Inc. may elect to file a startup, shutdown, and 

malfunction assertion under 10 CSR 10-6.050 if appropriate to the situation. 

3) Proper maintenance: At all times, the permittee shall maintain the monitoring, including but not 

limited to, maintaining necessary parts for routine repairs of the monitoring equipment. [§64.7(b)]

4) Continued operation: Except for, as applicable, monitoring malfunctions, associated repairs, and 

required quality assurance or control activities, the permittee shall collect data at all required 

intervals when the emission unit is operating. Data recorded during monitoring malfunctions, 

associated repairs, and required quality assurance or control activities shall not be used for purposes 

of part 64. The permittee shall use all the data collected during all other periods in assessing the 

operation of the control device and associated control system. A monitoring malfunction is any 

sudden, infrequent, not reasonably preventable failure of the monitoring to provide valid data. 

Monitoring failures that are caused in part by poor maintenance or careless operation are not 

malfunctions. [§64.7(c)]

5) Response to exceedances: [§64.7(d)]
Noranda Aluminum, Incorporated Part 70 Operating Permit 56

Installation ID: 143-0008 Project No. 2005-10-032

a) Upon detecting an exceedance, the permittee shall restore operation of the emission unit 

(including the control device and associated capture system) to its normal or usual manner of 

operation as expeditiously as practicable in accordance with good air pollution control practices 

for minimizing emissions. The response shall include minimizing the period of any startup, 

shutdown or malfunction and taking any necessary corrective actions to restore normal operation 

and prevent the likely recurrence of the cause of an exceedance (other than those caused by 

excused startup or shutdown conditions). Such actions may include initial inspection and

evaluation, recording that operations returned to normal without operator action (such as through 

response by a computerized distribution control system), or any necessary follow-up actions to 

return operation to within the indicator range, designated condition, or below the applicable 

emission limitation or standard, as applicable. [§64.7(d)(1)]

b) Determination of whether the permittee has used acceptable procedures in response to an 

excursion or exceedance will be based on information available, which may include but is not 

limited to, monitoring results, review of operation and maintenance procedures and records, and 

inspection of the control device, associated capture system, and the process. [§64.7(d)(2)]

Recordkeeping:

1) General Recordkeeping Requirements: 

a) The permittee shall comply with the recordkeeping requirements specified in §70.6(a)(3)(ii). The 

permittee shall maintain records of monitoring data, monitor performance data, corrective 

actions taken, any written quality improvement plan required pursuant to §64.8 and any activities 

undertaken to implement a quality improvement plan, and other supporting information required 

to be maintained under part 64 (such as data used to document the adequacy of monitoring, or 

records of monitoring maintenance or corrective actions). [§64.9(b)(1)]

b) Instead of paper records, the permittee may maintain records on alternative media, such as 

microfilm, computer files, magnetic tape disks, or microfiche, provided that the use of such 

alternative media allows for expeditious inspection and review, and does not conflict with other 

applicable recordkeeping requirements. [§64.9(b)(2)]

2) All records shall be maintained for five years. 

3) These records shall be made available immediately for inspection to the Department of Natural 

Resources' personnel upon their verbal request and presentation of identification.

Reporting:

1) General Reporting Requirements: The permittee shall submit semi-annual monitoring certified by a 

responsible official using the semi-annual monitoring report and annual compliance certification to 

the Air Pollution Control Program Enforcement Section, P.O. Box 176, Jefferson City, MO 65102, 

as required by 10 CSR 10-6.065(6)(C)1.C.(III). The report shall include, at a minimum, the 

following information, as applicable: [§64.9(a)(1) & (2)]

a) All instances of deviations from permit requirements must be clearly identified; 

b) Prompt reporting of deviations from permit requirements, including those attributable to upset 

conditions as defined in the permit, the probable cause of such deviations, and any corrective 

actions or preventive measures taken; 

c) Summary information on the number, duration and cause (including unknown cause, if 

applicable) of excursions or exceedances, as applicable, and the corrective actions taken; 

[§64.9(a)(2)(i)]

d) Summary information on the number, duration and cause (including unknown cause, if 

applicable) for monitor downtime incidents (other than downtime associated with zero and span 

or other daily calibration checks, if applicable); and [§64.9(a)(2)(ii)]

40 CFR 64.8. Upon completion of a QIP, the permittee shall include in the next summary report 

documentation that the implementation of the plan has been completed and reduced the 

likelihood of similar levels of excursions or exceedances occurring. [§64.9(a)(2)(iii)].

2) Documentation of need for improved monitoring: If the permittee identifies a failure to achieve 

compliance with this permit condition for which the approved monitoring did not provide an 

indication of an exceedance while providing valid data, or the results of compliance or performance 

testing document a need to modify the existing indicator ranges or designated conditions, the 

permittee shall promptly notify the Air Pollution Control Program and, if necessary, submit a 

proposed modification to the part 70 permit to address the necessary monitoring changes. Such a 

modification may include, but is not limited to, reestablishing indicator ranges or designated 

conditions, modifying the frequency of conducting monitoring and collecting data, or the monitoring 

of additional parameters. [§64.7(e)]

corrective action, and need to be reported in the next Semiannual Monitoring Report; if an excursion 

results in excess emissions exceeding one hour, Noranda Aluminum, Inc. may elect to file a startup, 

shutdown, and malfunction assertion under 10 CSR 10-6.050 if appropriate to the situation. 

3) Proper maintenance: At all times, the permittee shall maintain the monitoring, including but not 

limited to, maintaining necessary parts for routine repairs of the monitoring equipment. [§64.7(b)]

4) Continued operation: Except for, as applicable, monitoring malfunctions, associated repairs, and 

required quality assurance or control activities, the permittee shall collect data at all required 

intervals when the emission unit is operating. Data recorded during monitoring malfunctions, 

associated repairs, and required quality assurance or control activities shall not be used for purposes 

of part 64. The permittee shall use all the data collected during all other periods in assessing the 

operation of the control device and associated control system. A monitoring malfunction is any 

sudden, infrequent, not reasonably preventable failure of the monitoring to provide valid data. 

Monitoring failures that are caused in part by poor maintenance or careless operation are not 

malfunctions. [§64.7(c)]

5) Response to exceedances: [§64.7(d)]

a) Upon detecting an exceedance, the permittee shall restore operation of the emission unit 

(including the control device and associated capture system) to its normal or usual manner of 

operation as expeditiously as practicable in accordance with good air pollution control practices 

for minimizing emissions. The response shall include minimizing the period of any startup, 

shutdown or malfunction and taking any necessary corrective actions to restore normal operation 

and prevent the likely recurrence of the cause of an exceedance (other than those caused by 

excused startup or shutdown conditions). Such actions may include initial inspection and 

evaluation, recording that operations returned to normal without operator action (such as through 

response by a computerized distribution control system), or any necessary follow-up actions to

return operation to within the indicator range, designated condition, or below the applicable 

emission limitation or standard, as applicable. [§64.7(d)(1)]

b) Determination of whether the permittee has used acceptable procedures in response to an 

excursion or exceedance will be based on information available, which may include but is not 

limited to, monitoring results, review of operation and maintenance procedures and records, and 

inspection of the control device, associated capture system, and the process. [§64.7(d)(2)]

Recordkeeping:

1) General Recordkeeping Requirements: 

a) The permittee shall comply with the recordkeeping requirements specified in §70.6(a)(3)(ii). The 

permittee shall maintain records of monitoring data, monitor performance data, corrective 

actions taken, any written quality improvement plan required pursuant to §64.8 and any activities 

undertaken to implement a quality improvement plan, and other supporting information required 

to be maintained under part 64 (such as data used to document the adequacy of monitoring, or 

records of monitoring maintenance or corrective actions). [§64.9(b)(1)]

b) Instead of paper records, the permittee may maintain records on alternative media, such as 

microfilm, computer files, magnetic tape disks, or microfiche, provided that the use of such 

alternative media allows for expeditious inspection and review, and does not conflict with other 

applicable recordkeeping requirements. [§64.9(b)(2)]

2) All records shall be maintained for five years. 

3) These records shall be made available immediately for inspection to the Department of Natural 

Resources' personnel upon their verbal request and presentation of identification.

Aluminum Reduction Plants

Emission Limitation:

The owner or operator shall not discharge or cause to be discharged into the atmosphere any emissions 

of total fluorides (TF) in excess of 0.95 kg/Mg (1.9 lb/ton) of aluminum produced for each center 

worked prebake one (CWPB1) potline. [§63.843(a)(1)(i)]

Monitoring:

1) Performance Testing: All performance tests shall be conducted in accordance with the requirements 

of the general provisions in Subpart A of 40 CFR Part 63, the approved test plan, and the procedures 

in this section. [§63.847(d)]

a) TF emissions from potlines. For each potline, the owner or operator shall measure and record the 

emission rate of TF exiting the outlet of the primary control system for each potline and the rate 

of secondary emissions exiting through each roof monitor. Using the equation in §63.847(e)(1), 

the owner or operator shall compute and record the average of at least three runs each month for 

secondary emissions and at least three runs each year for the primary control system to determine 

compliance with the applicable emission limit. Compliance is demonstrated when the emission 

rate of TF is equal to or less than the applicable emission limit in §63.843(a)(1)(i). 

[§63.847(d)(1) & §63.847(e)(1)].

primary emission control device(s) for a potline during the previous consecutive 12 months, the 

average of all runs performed in the previous 12-month period shall be used to determine the 

contribution from the primary emission control system. [§63.847(d)(3)]

2) Selection of Monitoring Parameters.

The owner or operator shall determine the operating limits and monitoring frequency for each 

control device that is to be monitored as required in §63.848(f). [§63.847(h)]

a) For potlines, the owner or operator shall determine upper and/or lower operating limits, as 

appropriate, for each monitoring device for the emission control system from the values recorded 

during each of the runs performed during the initial performance test and from historical data 

from previous performance tests conducted by the methods specified in this subpart. 

[§63.847(h)(1)]

b) The owner or operator may redetermine the upper and/or lower operating limits, as appropriate, 

based on historical data or other information and submit an application to the applicable 

regulatory authority to change the applicable limit(s). The redetermined limits shall become 

effective upon approval by the applicable regulatory authority. [§63.847(h)(3)]

3) Emission Monitoring: 

a) Using the procedures in §63.847 and in the approved test plan, the owner or operator shall 

monitor emissions of TF from each potline by conducting monthly performance tests. The 

owner or operator shall compute and record the monthly average from at least three runs for 

secondary emissions and the previous 12-month average of all runs for the primary control 

system to determine compliance with the applicable emission limit. The owner or operator must 

include all valid runs in the monthly average. The duration of each run for secondary emissions 

must represent a complete operating cycle. [§63.848(a)]

b) As an alternative to monthly monitoring of TF secondary emissions from each potline using the 

test methods in §63.849, the owner or operator may perform monthly monitoring of TF

secondary emissions from one potline using the test methods in §§63.849 (a) or (b) to represent 

the performance of similar potline(s). The similar potline(s) shall be monitored using an 

alternative method that meets the requirements of §§63.848(d)(1) through (d)(7) of this section. 

Two or more potlines are similar if the owner or operator demonstrates that their structure, 

operability, type of emissions, volume of emissions, and concentration of emissions are 

substantially equivalent. [§63.848(d)]

c) Reduced sampling frequency. The owner or operator may submit a written request to the 

applicable regulatory authority to establish an alternative testing requirement to reduce the 

sampling of secondary TF emissions from potlines from monthly to quarterly. [§63.848(e)]

i) In the request, the owner or operator shall provide information and data demonstrating, to the 

satisfaction of the applicable regulatory authority, that secondary emissions of TF from 

potlines have low variability during normal operations using the procedures in 

§63.848(e)(1)(i) or (e)(1)(ii). [§63.848(e)(1)]

(1) Submit data from 24 consecutive months of sampling that show the average TF emissions 

are less than 60 percent of the applicable limit and that no monthly performance test in 

the 24 months of sampling exceeds 75 percent of the applicable limit; or 

[§63.848(e)(1)(i)]

(2) Submit data and a statistical analysis that the regulatory authority may evaluate based on 

the approach used in ―Primary Aluminum: Statistical Analysis of Potline Fluoride 

Emissions and Alternative Sampling Frequency‖ (EPA–450–86–012, October 1986), 
Noranda Aluminum, Incorporated Part 70 Operating Permit 70

which is available from the National Technical Information Service (NTIS), 5285 Port 

Royal Road, Springfield, VA 22161. [§63.848(e)(1)(ii)]

ii) An approved alternative requirement must include a test schedule and the method to be used 

to measure emissions for performance tests. [§63.848(e)(2)]

iii) The owner or operator of a plant that has received approval of an alternative sampling 

frequency under §60.194 of this chapter is deemed to have approval of the alternative 

sampling frequency under this subpart. [§63.848(e)(3)]

iv) If emissions in excess of the applicable TF limit occur while performing quarterly sampling 

approved under paragraph (e)(1)(i) of this section, the owner or operator shall return to 

monthly sampling for at least 12 months and may reduce to quarterly sampling when: 

[§63.848(e)(4)]

(1) The average of all tests performed over the most recent 24-month period does not exceed 

60 percent of the applicable limit, and [§63.848(e)(4)(i)]

(2) No more than one monthly performance test in the most recent 24-month period exceeds 

75 percent of the applicable limit. [§63.848(e)(4)(ii)]

v) If emissions in excess of the applicable TF limit occur while performing quarterly sampling 

approved under §63.848(e)(1)(ii), the owner or operator shall immediately return to the 

monthly sampling schedule required by §63.848(a) until another request for an alternative 

sampling frequency is approved by the applicable regulatory authority. [§63.848(e)(5)]

4) Monitoring Parameters for Emission Control Devices: The owner or operator shall install, operate, 

calibrate, and maintain a continuous parameter monitoring system for each emission control device. 

The owner or operator shall submit for approval by the regulatory authority a description of the 

parameter(s) to be monitored, the operating limits, and the monitoring frequency to ensure that the 

control device is being properly operated and maintained. An explanation of the criteria used for 

selection of the parameter(s), the operating limits, and the monitoring frequency, including how 

these relate to emission control also shall be submitted to the regulatory authority. Except as 

provided in §63.848(l), for dry alumina scrubbers, devices for the measurement of alumina flow and 

air flow shall be installed. [§63.848(f)(1)]

5) Visible Emission: The owner or operator shall visually inspect the exhaust stack(s) of each control 

device on a daily basis for evidence of any visible emissions indicating abnormal operation. 

[§63.848(g)]

6) Corrective Action: If a monitoring device for a primary control device measures an operating

parameter outside the limit(s) established pursuant to §63.847(h), if visible emissions indicating 

abnormal operation are observed from the exhaust stack of a control device during a daily 

inspection, or if a problem is detected during the daily inspection of a wet roof scrubber for potline 

secondary emission control, the owner or operator shall initiate corrective action procedures within 1 

hour. Failure to initiate the corrective action procedures within 1 hour or to take the necessary 

corrective actions to remedy the problem is a violation. [§63.848(h)]

7) Exceedances: If the limit for a given operating parameter associated with monitoring a specific 

control device is exceeded six times in any semiannual reporting period, then any subsequent 

exceedance in that reporting period is a violation. For the purpose of determining the number of 

exceedances, no more than one exceedance shall be attributed in any given 24-hour period. 

[§63.848(i)]

8) Weight of Aluminum: The owner or operator install, operate, and maintain a monitoring device to 

determine the daily weight of aluminum produced. [§63.848(j)]

Monitoring:

1) The permittee shall conduct opacity readings on the emission unit(s) using the procedures contained 

in USEPA Test Method 22. At a minimum, the observer should be trained and knowledgeable about 

the effects on visibility of emissions caused by background contrast, ambient lighting, observer 

position relative to lighting, wind and the presence of uncombined water. Readings are only 

required when the emission unit(s) is operating and when the weather conditions allow. If no visible 

or other significant emissions are observed using these procedures, 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.

2) The following monitoring schedule must be maintained:

a) Observations must be made once per month. If a violation is noted, then 

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

no violation of this regulation be observed during this period then monitoring reverts to monthly 

monitoring.

Eb = emission rate of TF, kg/mg (lb/ton) of green anodes produced;

Cs = concentration of TF, mg/dscm (mg/dscf);

Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/hr);

Pb = quantity of green anode material placed in the furnace, mg/hr (ton/hr); and

K = conversion factor, 106 mg/kg (453,600 mg/lb).

ii) Compute the emission rate of POM from each anode bake furnace using Equation 2 of 

§63.847(e),

Where: 

Cs = concentration of POM, mg/dscm (mg/dscf)

b) Previous Control Device Tests. If the owner or operator has performed more than one test of 

primary emission control device(s) for a bake furnace during the previous consecutive 12 

months, the average of all runs performed in the previous 12-month period shall be used to 

determine the contribution from the primary emission control system.. [§63.847(d)(3)]

2) Selection of Monitoring Parameters.

The owner or operator shall determine the operating limits and monitoring frequency for each 

control device that is to be monitored as required in §63.848(f). [§63.847(h)]

a) For anode bake furnaces, the owner or operator shall determine upper and/or lower operating 

limits, as appropriate, for each monitoring device for the emission control system from the values 

recorded during each of the runs performed during the initial performance test and from 

historical data from previous performance tests conducted by the methods specified in this 

subpart.. [§63.847(h)(1)]

b) The owner or operator may redetermine the upper and/or lower operating limits, as appropriate, 

based on historical data or other information and submit an application to the applicable 

regulatory authority to change the applicable limit(s). The redetermined limits shall become

calibrate, and maintain a continuous parameter monitoring system for each emission control device. 

The owner or operator shall submit for approval by the regulatory authority a description of the 

parameter(s) to be monitored, the operating limits, and the monitoring frequency to ensure that the 

control device is being properly operated and maintained. An explanation of the criteria used for 

selection of the parameter(s), the operating limits, and the monitoring frequency, including how 

these relate to emission control also shall be submitted to the regulatory authority. Except as 

provided in §63.848(l), for dry alumina scrubbers, devices for the measurement of alumina flow and 

air flow shall be installed. [§63.848(f)(1)]

5) Visible Emission: The owner or operator shall visually inspect the exhaust stack(s) of each control 

device on a daily basis for evidence of any visible emissions indicating abnormal operation. 

[§63.848(g)]

6) Corrective Action: If a monitoring device for a primary control device measures an operating 

parameter outside the limit(s) established pursuant to §63.847(h), if visible emissions indicating 

abnormal operation are observed from the exhaust stack of a control device during a daily

inspection, the owner or operator shall initiate corrective action procedures within 1 hour. Failure to 

initiate the corrective action procedures within 1 hour or to take the necessary corrective actions to 

remedy the problem is a violation. [§63.848(h)]

7) Exceedances: If the limit for a given operating parameter associated with monitoring a specific 

control device is exceeded six times in any semiannual reporting period, then any subsequent 

exceedance in that reporting period is a violation. For the purpose of determining the number of 

exceedances, no more than one exceedance shall be attributed in any given 24-hour period. 

[§63.848(i)]

8) Weight of Green Anodes. The owner or operator of a new or existing anode bake furnace shall 

install, operate, and maintain a monitoring device to determine the daily weight of green anode 

material placed in the anode bake furnace. The weight of green anode material may be determined 

by monitoring the weight of all anodes or by monitoring the number of anodes placed in the furnace 

and determining an average weight from measurements of a representative sample of anodes.. 

[§63.848(j)]

9) Accuracy and Calibration: The owner or operator shall submit recommended accuracy 

requirements to the regulatory authority for review and approval. All monitoring devices required by 

this section must be certified by the owner or operator to meet the accuracy requirements and must 

be calibrated in accordance with the manufacturer's instructions. [§63.848(k)]

10) Alternative Operating Parameters: The owner or operator may monitor alternative control device 

operating parameters subject to prior written approval by the applicable regulatory authority.

Emission Limitation:

On and after the date on which the performance test required to be conducted by §60.8 is completed, no 

owner or operator subject to the provisions of this subpart shall cause to be discharged into the 

atmosphere from any anode bake plant any gases which exhibit 20 percent opacity or greater. 

[§60.193(a)(2)]

Monitoring:

1) The permittee shall conduct opacity readings on the emission unit(s) using the procedures contained 

in USEPA Test Method 22. At a minimum, the observer should be trained and knowledgeable about 

the effects on visibility of emissions caused by background contrast, ambient lighting, observer 

position relative to lighting, wind and the presence of uncombined water. Readings are only 

required when the emission unit(s) is operating and when the weather conditions allow. If no visible 

or other significant emissions are observed using these procedures, 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.

2) The following monitoring schedule must be maintained:

a) Observations must be made once per month. If a violation is noted, then 

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

no violation of this regulation be observed during this period then monitoring reverts to monthly 

monitoring. 

Record keeping:

1) The permittee shall maintain records of all observation results (see Attachment B), noting:

a) Whether any air emissions (except for water vapor) were visible from the emission units,

b) All emission units from which visible emissions occurred, and

c) Whether the visible emissions were normal for the process.

d) The permittee shall maintain records of any equipment malfunctions.

2) The permittee shall maintain records of any other Method 9 test performed in accordance with this 

permit condition. (See Attachment C)

Reporting:

1) The permittee shall report to the Air Pollution Control Program Enforcement Section, P.O. Box 176,

10 CSR 10-6.065(6)(C)8 Operational Flexibility

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, Enforcement Section, P.O. Box 

176, Jefferson City, MO 65102, as well as EPA Region VII, 901 North 5th Street, Kansas City, Kansas 

66101, at least seven 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 establishes 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. 

1) 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, Enforcement Section, P.O. Box 176, Jefferson City, MO 

65102, as well as EPA Region VII, 901 North 5th Street, Kansas City, Kansas 66101, describing 

the changes to be made, the date on which the change 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 the APCP shall place a copy with the permit in the public file. 

Written notice shall be provided to the EPA and the APCP as above at least seven days before 

the change is to be made. If less than seven days notice is provided because of a need to respond 

more quickly to these unanticipated conditions, the permittee shall provide notice to the EPA and 

the APCP as soon as possible after learning of the need to make the change.

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

10 CSR 10-6.065(6)(C)9 Off-Permit Changes

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 Air Pollution Control Program, 

Enforcement Section, P.O. Box 176, Jefferson City, MO 65102, as well as EPA Region VII, 901 

North 5th Street, Kansas City, Kansas 66101, no later than the next annual emissions report. This 

notice shall not be required for changes that are insignificant activities under 10 CSR 10-

6.065(6)(B)3. 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.

The key elements of the baghouse compliance assurance monitoring, including the performance indicator 

parameter, the performance indicator parameter range, and performance monitoring criteria are summarized in 

Table 1.

TABLE 1. BAGHOUSE MONITORING SUMMARY

Indicator Pressure drop Visible emissions 

Measurement Approach Pressure drop across the baghouse filter 

system is measured with a differential 

pressure gauge. 

A daily visible emissions observation will be 

performed, using a 6-minute EPA Reference 

Method 22-like observation. 

Indicator Range An excursion is defined as a pressure 

drop outside the established pressure 

drop range for each unit (see attached 

Table 2). Excursions trigger an 

inspection and corrective action, and a 

reporting requirement. 

The acceptable parameter range is ―no visible 

emissions‖. 

QIP Threshold NA The QIP threshold for any individual emission 

unit is 9 excursions in a 6-month reporting 

period. If an individual emission unit reaches the 

QIP threshold, Noranda will submit a QIP for 

that emission unit along with the semiannual 

report for that reporting period.

Indicator Pressure drop Visible emissions 

Data Representativeness Pressure taps are located at the 

baghouse inlet and outlet. 

Measurements will be made at the baghouse 

exhaust, which are representative of the visible 

emissions of this unit.

Status of Indicator 

Measurement Device 

NA NA 

QA/QC Practices and Criteria The dust collector will be operated and 

maintained in accordance with 

Noranda’s Air Control Operations 

Manual. Pressure drop measurements 

that indicate a pressure drop outside of 

the specified performance criteria range 

will be investigated. Quarterly 

inspections of the filter system for 

leaks, wear or other abnormalities will 

be completed. The pressure indicating 

instrument will be calibrated in 

accordance with manufacturer’s 

recommendations. 

The observer will be familiar with Reference 

Method 22 and Method 22-like procedures. 

Performance Indicator 

Measurement Frequency and 

Data Collection Procedures 

Since the controlled emissions for the 

emission units are less than the major 

source threshold, the pressure drop will 

be recorded once daily. The pressure 

drop reading may be taken manually by 

plant personnel or recorded 

automatically via plant control system 

computers. 

A daily visible emissions observation will be 

performed, using a 6-minute EPA Reference 

Method 22-like observation. Records of these 

daily observations will include the time and date 

the assessment occurred, baghouse operational 

status, whether any emissions were observed, 

steps taken to correct any abnormal emissions, 

and the name of the person conducting the 

assessment. 

CAM JUSTIFICATION

I. BACKGROUND 

The emission units included in this CAM Plan were determined to subject to CAM, since the emission units 

meet the three CAM applicability criteria listed in 40 CFR 64. The emission units are controlled by a baghouse 

(CD-4), and this CAM Plan details the compliance assurance monitoring that will be performed on the 

baghouse. 

II. RATIONALE FOR SELECTION OF PERFORMANCE INDICATORS 

Pressure Drop across the filter system: Per Appendix H of the Operating Permit Application Instructions 

provided by the Missouri Department of Natural Resources, the pressure drop across the filter system can be 

used to measure the performance of a baghouse. In addition, Appendix A.10 of EPA’s CAM Technical 

Guidance document lists pressure drop as an indicator of baghouse performance. 

Visible Emissions at the baghouse exhaust: Appendix A.10 of EPA’s CAM Technical Guidance document 

lists visible emissions at the baghouse exhaust as an indicator of baghouse performance. 
Noranda Aluminum, Incorporated Part 70 Operating Permit 137

Installation ID: 143-0008 Project No. 2005-10-032

III. RATIONALE FOR INDICATOR RANGE SELECTION 

Pressure Drop across the filter system: Noranda is required by the current Title V operating permit to monitor 

the pressure drop across the baghouse on a weekly basis. The historical pressure drop data for the baghouse was 

reviewed to establish the upper and lower bounds of the pressure drop range for the daily pressure drop 

monitoring. 

Noranda has been conducting weekly pressure drop monitoring in accordance with the existing Title V permit 

to demonstrate compliance with the PM limits established by 10-6.400. The weekly pressure drop 

measurements were used to establish the upper and lower bounds of the pressure drop range for the daily 

pressure drop monitoring that will be used to demonstrate compliance with both the PM limits established by 

10-6.400 and PSD Permit 102004-001. 

While the pressure drop will be monitored to determine if the pressure drop falls in the range observed for the 

historical data, operation of the baghouse outside of the proposed pressure drop range does not mean the 

baghouse is not functioning normally, and it does not necessarily indicate a change in the efficiency of the 

baghouse. Noranda established with the issuance of PSD permit 102004-001 that baghouses and their associated 

fans operate in an on/off manner, and as long as a baghouse is on, the emissions from the baghouse remain 

constant, as the effluent particle concentration is nearly constant based on the filter design. The U.S. EPA Air 

Pollution Control Technology Fact Sheets, document numbers EPA-452/F03-024 and EPA-452/F03-025, 

Achievable Emission Limits further support baghouses being constant outlet devices. The fact sheets state the 

following, 

“For a given combination of filter design and dust, the effluent particle concentration from a fabric filter is 

nearly constant,.. For this reason, fabric filters can be considered to be constant outlet devices...”

It has been determined that the baghouse is required to meet PM/PM10 limits. As long as the baghouse is on, 

compliance with the PM/PM10 limits will be achieved. Therefore, a broad range of pressure drops will indicate 

that the unit is on and functioning normally. The indicator range for this baghouse was selected based on the full 

range of pressure drop data available from the monitoring data required by the current Title V permit. A 

pressure drop reading outside the range included in this CAM plan does not indicate an exceedance of the 

associated PM/PM10 limit. Pressure drop readings outside the established range will be treated as an excursion 

and investigated to determine if further corrective action is required to get back into the established indicator 

range. The steps in the investigation of these excursions, and, if needed, any resulting corrective actions, will be 

documented. Corrective action will begin as soon as practical, but no later than the end of the shift on which the 

excursion was noted. The time to complete the corrective action will vary depending on the severity of the

problem causing the excursion. 

Visible Emissions at the baghouse exhaust: The selected indicator range is no visible emissions. Measurements 

will be made at the baghouse exhaust, which are representative of the visible emissions of this unit. Daily 

visible emissions readings will be done in lieu of performance testing of the units to demonstrate compliance 

with the particulate matter limits. No visible emissions using a Method 22-like procedure will be used to 

demonstrate compliance with both the PM limits established by 10-6.400 and PSD Permit 102004-001.A daily 

visible emissions observation will be performed, using a 6-minute EPA Reference Method 22-like observation 

of the baghouse exhaust during unit operation. Records of these daily observations will include the time and 

date the assessment occurred, baghouse operational status, whether any emissions were observed, steps taken to 

correct any abnormal emissions, and the name of the person conducting the assessment. Visible emission 

readings outside the range included in this CAM plan do not indicate an exceedance of the associated limit. 

Readings outside the established range will be treated as an excursion and investigated to determine if further 

corrective action is required. The steps in the investigation of these excursions, and, if needed, any resulting 
Noranda Aluminum, Incorporated Part 70 Operating Permit 138

Installation ID: 143-0008 Project No. 2005-10-032

corrective actions, will be documented. Daily visible emissions readings will be done in lieu of performance 

testing of the units to demonstrate compliance with the particulate matter limits. 

CAM TESTING AND IMPLEMENTATION PLAN 

I. TEST PLAN 

Pressure Drop across the filter system: Noranda has been utilizing pressure drop measurements on the 

baghouse for the past five years as an indicator of the baghouse performance. In order to fulfill the CAM 

requirements for the baghouse, Noranda is increasing the pressure-drop measurement frequency to once per 

day. Since historical data indicating the performance of the baghouse was used to establish the pressure drop 

range for the baghouse, no testing is necessary to establish the relationship between the pressure drop range and 

baghouse performance. 

Visible emissions at the baghouse exhaust: Appendix A.10 of EPA’s CAM Technical Guidance document lists 

visible emissions at the baghouse exhaust as an indicator of baghouse performance. 

No testing is necessary to establish the relationship between the visible emissions monitoring and baghouse 

performance. 

II. IMPLEMENTATION PLAN 

Pressure Drop across the filter system: No CAM implementation plan is necessary. The infrastructure for 

operating and maintaining the pressure indicating devices are in place.

Visible emissions at the baghouse exhaust: No CAM implementation plan is necessary. 

OPERATING PARAMETER RANGES FOR NORANDA BAGHOUSES SUBJECT TO CAM PLAN 

REQUIREMENTS

The CAM Plan for Baghouse CD-4 is being submitted as a template for the 19 baghouses that will be subject to 

CAM requirements upon CAM renewal. The CAM Plan document will be the same for each of the remaining 

baghouses, with the pressure drop range in each plan specific to that baghouse. The pressure drop range 

documented in the existing monitoring records for each baghouse is summarized in Table 2 below.

Applicable Requirements Included in the Operating Permit but Not in the Application or Previous 

Operating Permits

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.

None.
Noranda Aluminum, Incorporated Part 70 Operating Permit SB - 2

Installation ID: 143-0008 Project No. 2005-10-032

Other Air Regulations Determined Not to Apply to the Operating Permit 

The Air Pollution Control Program (APCP) has determined the following requirements to not be 

applicable to this installation at this time for the reasons stated. 

1) 10 CSR 10-6.100, Alternate Emission Limits

This rule is not applicable because the installation is in an ozone attainment area.

2) 10 CSR 10-6.260, Restriction of Emission of Sulfur Compounds

This rule exempts combustion equipment that uses exclusively pipeline grade natural gas as defined 

in 40 CFR 72.2 or liquefied petroleum gas as defined by American Society for Testing and Materials 

(ASTM), or any combination of these fuels. 

All combustion equipment at the installation uses pipeline grade natural gas and /or propane and is 

exempt from the requirements of this rule.

3) 40 CFR Part 63, Subpart DDDDD, National Emission Standards for Industrial, Commercial and 

Institutional Boilers and Process Heaters

40 CFR 63, Subpart DDDDD was issued on February 21, 2011 EPA. Subpart DDDDD applies to 

boilers and process heaters located at a major source of hazardous air pollutants (HAPS). The 

affected sources include new and existing solid and liquid fuel-fired boilers and process heaters. 

Direct-fired combustion units are not affected units for this subpart.

Small boilers and process heaters are defined as any firetube boiler (regardless of size) and any other 

boiler or process heater < 10 MMBtu/hr. Large boiler and heaters are defined as any boiler or 

process heater > 10 MMBtu/hr. Existing small units (all fuel types) and new small units (gas fuels) 

have no emission limits or other applicable requirements (monitoring, record keeping, or 

notification). Noranda operates existing small natural gas-fired boilers and process heaters. Existing 

small natural gas fired boilers at Noranda’s facility include EU3730 (EP-94), EU3740 (EP-93, 

EU3750 (EP-96), EU3755 (EP-97, labeled as EU3760 in OP2001032), EU4900 (EPSI), EU4910 

(EP-BJ) and EU4920 (EP-BK). (EP-97 is given a new Emission Unit number in the renewal 

application since, in the initial Part 70 permits, there are two emission units EU-3760; one in 

OP2001032 and one in OP2001062). These existing small natural gas-fired units are not subject to 

any requirements of Subpart DDDDD. 

Noranda operates three existing large, natural gas direct-fired furnaces including EU4790 (EP-AJ), 

EU4800 (EP-AK), and EU48 10 (EP-AL). Since these units are direct-fired, these are not affected 

units for this subpart.

4) 10 CSR 10-6.090, Restriction of Emission of Fluorides from Primary Aluminum Reduction 

Installations

This rule applies to primary (stack) emissions of total fluoride from potroom groups and anode bake 

plants within a primary aluminum reduction installation constructed before August 13, 1981, the 

effective date of this rule, except where New Source Performance Standards apply (as provided in 10 

CSR 10-6.070). The potroom stacks and anode bake stacks constructed before August 13, 1981 are 

subject to the 40 CFR Part 60, Subpart S, Standards of Performance for Primary Aluminum 

Reduction Plants and the more stringent requirements of 40 CFR Part 63, Subpart LL (Primary 
Noranda Aluminum, Incorporated Part 70 Operating Permit SB - 3

Installation ID: 143-0008 Project No. 2005-10-032

Aluminum MACT), therefore this rule is not included as an applicable requirement in this operating 

permit. 

Construction Permit Revisions

10 CSR 10-6.060, Construction Permits Required

When a Construction Permit is incorporated into the Operating Permit, all aspects of the 

Construction Permit relating to emissions are to be maintained for an installation to be in 

compliance. According to 10 CSR 10-6.060, Construction Permits Required the Construction 

Permit consists of both the issued permit and Construction Permit application.

10 CSR 10-6.060 (6)(E)3. – ―Any owner or operator who constructs, modifies or operates an 

installation not in accordance with the application submitted and the permit issued, including any 

terms and conditions made a part of the permit, or any owner or operator of an installation who 

commences construction or modification after May 13, 1982, without meeting the requirements 

of this rule, is in violation of this rule;‖

Any installation that does not comply with the issued permit and Construction Permit application as 

it relates to emissions would be considered to be in violation of 10 CSR 10-6.060. 

The Construction Permit application consists of numerous parameters that are not included in either 

the Construction Permit or the Operating Permit. Some examples of the criteria necessary for the 

application are site information; descriptions; plans; control efficiencies; flow parameters; design 

specifications; and drawings showing the design of the installation, the nature and amount of 

emission of each pollutant, and the manner in which emission units will be operated and controlled. 

These values submitted in the Construction Permit application define the criteria the regulatory 

agencies use to evaluate potential emissions and determine the ambient air quality of the surrounding 

area. It is essential the installation operate and construct the emission units according to the criteria 

related to emissions in the Construction Permit application, since the criteria are the basis behind the 

limitations established in the Construction Permit. If any of the parameters relating to emissions 

should change, the installation would be required to request and obtain a modification to their 

Construction Permit. 

While an installation must adhere to their Construction Permit application, it is not necessary for the 

installation to certify and monitor each application parameter to show compliance. The installation 

is only required to monitor those parameters defined in specific State or Federal requirements or 

identified as Special Conditions in the Construction Permit. When construction permits are placed 

in Plant-wide and Emission Unit permit conditions in the Operating Permit, the installation is 

required to certify compliance with the parameters (monitoring, performance testing, record keeping 

and reporting) identified in the Plant-wide and Emission Unit permit conditions of the Operating 

Permit. However, the various parameters detailed in the Construction Permit application are still 

applicable to the installation, even though the criteria are not specifically listed in the Operating 

Permit. 

New Source Performance Standards (NSPS) Applicability

10 CSR 10-6.070, New Source Performance Regulations

40 CFR Part 60 Subpart S, Standards of Performance for Primary Aluminum Reduction Plants

This subpart applies to potroom groups and anode bake plants that commence construction or 

modification after October 23, 1974. Potline 3 (EU2010, EU2030, and EU2050) and Carbon Bake 3 
Noranda Aluminum, Incorporated Part 70 Operating Permit SB - 4

Installation ID: 143-0008 Project No. 2005-10-032

(EU4360 through EU4700) were permitted in June of 1979 and were constructed sometime after this 

date and are, therefore, subject to this rule.

According to §60.190(c), an owner or operator of an affected facility may elect to comply with the 

requirements of Subpart S or the requirement of Subpart LL of Part 63. Consequently, Permit 

Conditions EU2010-004, EU2030-004, EU2050-004, and EU(4360-4700)-004 establish TF and 

POM requirements as put forth in subpart LL of Part 63. However, as there are no applicable 

opacity requirements in subpart LL, Permit Conditions EU2010-003, EU2030-003, EU2050-003, 

and EU(4360-4700)-003 were included to establish opacity requirements as put forth in Subpart S of 

Part 60.

Maximum Achievable Control Technology (MACT) Applicability

10 CSR 10-6.075, Maximum Achievable Control Technology Regulations 

1) 40 CFR Part 63 Subpart LL, National Emission Standards for Hazardous Air Pollutants for Primary 

Aluminum Reduction Plants

According to §63.840 – Applicability, the requirements of this subpart apply to the owner or 

operator of each new pitch storage tank and new or existing potline, paste production plant, or anode 

bake furnace associated with primary aluminum production and located at a major source as defined 

in §63.2. The requirements of this subpart do not apply to any existing anode bake furnace that is 

not located on the same site as a primary aluminum reduction plant. 

Therefore, this rule applies to the three potlines (EU1970 through EU2050), the paste production 

plant (EU3240 through EU3270) and the anode bake furnaces (EU3760 through EU4700). The 

pitch day storage tank, EU3690 through EU3720, is part of the paste production plant and therefore 

does not meet the definition of pitch storage tank in §63.842. Consequently, EU3690 through 

EU3720 are not subject to §63.844(d) and §63.847(g).

2) 40 CFR 63 Subpart RRR, National Emission Standards for Hazardous Air Pollutants for Secondary 

Aluminum Production 

According to § 63.1500, applicability of this subpart ,this rule applies to the melting furnaces, the 

holding furnaces, the pig melter, the charge furnaces, and the cone casting furnace (EU4710 through 

EU4780 and EU4830 through EU4890).

a) Add-on pollution control devices will be used to meet the requirements of Subpart RRR.

b) Charge other than clean charge only will be used in the furnaces.

c) No in-line fluxers are at the facility.

National Emission Standards for Hazardous Air Pollutants (NESHAP) Applicability

40 CFR Part 61 Subpart M, National Emission Standard for Asbestos, §61.145(a), Standard for 

demolition and renovation, applies to the installation.

Compliance Assurance Monitoring (CAM) Applicability

40 CFR Part 64, Compliance Assurance Monitoring (CAM)

The CAM rule applies to each pollutant specific emission unit that:

1) Is subject to an emission limitation or standard, and

2) Uses a control device to achieve compliance, and

3) Has pre-control emissions that exceed or are equivalent to the major source threshold.
Noranda Aluminum, Incorporated Part 70 Operating Permit SB - 5

Installation ID: 143-0008 Project No. 2005-10-032

Noranda’s emission units were evaluated against the criteria listed above. Emission units that satisfy 

all three criteria listed above for a specific regulated pollutant are subject to CAM for the control 

device. Prior to evaluating pollutant-specific CAM requirements, Noranda eliminated from CAM 

consideration all pollutants with limits established pursuant to a MACT or NSPS. For Noranda, the 

non-MACT or non-NSPS regulated pollutants include PM, PM10, VOC, CO, and S02.

SO2

SO2 is regulated under 10 CSR 10-6.260 for direct and indirect fired heaters and is regulated in PSD 

Permit 102004-001 (as amended in 102004-001A) for the potlines. None of the emission units 

subject to an SO2 emission limit use a control device for SO2 (Criteria #2 as listed above). 

Therefore, Noranda does not have any emission units that trigger CAM requirements for SO2. 

VOC

VOC is regulated under Construction Permit 0298-001 for the emission units associated with the 

green mill. None of the emission units subject to a VOC emission limit use a control device for 

VOC (Criteria #2 as listed above). Therefore, Noranda does not have any emission units that trigger 

CAM requirements for VOC.

CO

CO is regulated under PSD Construction Permit 102004-001 (as amended in 102004-001A) for the 

potlines. None of the emission units subject to a CO emission limit use a control device for CO 

(Criteria #2 as listed above). Therefore, Noranda does not have any emission units that trigger CAM 

requirements for CO.

PM and PM10

PM and PM10 are regulated under 10 CSR 10-6.400 and under PSD 102004-001 (as amended in 

102004-001A), respectively. Noranda adopted a tiered approach to evaluating which emission units 

at the facility are subject to CAM for PM and PM10. First, Noranda determined the emission units 

that meet CAM applicability criteria#1 as listed above (i.e. emission units that are subject to an 

emission limitation or standard for a regulated air pollutant, in this case PM and PM10). Second, for 

units that meet CAM applicability criteria #1, Noranda determined the emission units that meet 

CAM applicability criteria #3 as listed above (emission units with uncontrolled PTE greater than the 

major source threshold). Finally, for units that meet CAM applicability criteria #1 and CAM 

applicability criteria #3, Noranda determined the emission units that meet CAM Criteria #2 as listed 

above (i.e. emission units use a control device to achieve compliance with the emission limitation or 

standard).

All emission units are subject to a PM and/or a PM10 limit. Appendix A provides a summary of the 

PM and PM10 emission limits that were used in the CAM applicability analysis. Since all emission 

units are subject to a PM and/or a PM10 limit, all emission units meet CAM Criteria #1. Since all 

emission units meet CAM Criteria #1, the uncontrolled potential to emit (PTE) was compared to the 

major source threshold of 100 tons per year (tpy) to determine if the units meet CAM Criteria #3. 

Appendix A includes a summary of the units with an uncontrolled PTE for PM and PM10 above 100

tpy. Emission units with an uncontrolled PTE for either PM or PM10 greater than 100 tons per year 

were reviewed to determine if the units had a control device for PM or PM10 whose primary purpose 

was to achieve compliance with the applicable PM or PM10 limitation (CAM Criteria #2).
Noranda Aluminum, Incorporated Part 70 Operating Permit SB - 6

Installation ID: 143-0008 Project No. 2005-10-032

In order for CAM Criteria #2 to be satisfied, an emission unit subject to an emission standard must 

require a control device to meet the emission standard, where control device is defined as 

―equipment, other than inherent process equipment, that is used to destroy or remove air pollutant 

prior to discharge to the atmosphere.‖ It is possible for a piece of process equipment to be perceived 

as a control device, simply because it accomplishes emission reduction. However, equipment that is 

inherent to the process operation that achieves emission reduction as a co-benefit is not considered 

control equipment. 

Noranda operates a number of units with that meet CAM criteria #1 and #3, but that do not meet 

CAM Criteria #2. The next sections describe these units. 

A significant number of the material handling emission units have baghouses as part of pneumatic 

(air-driven) systems. The emission units with baghouses that are associated with pneumatic systems 

are listed in the following table (Summary of Emission Units Associated with Pneumatic Systems).

In a pneumatic system, a low pressure blower supplies air to lift material (i.e. fresh alumina ore, 

reacted alumina ore, or electrolytes recovered from the anodes) off the floor of the air slide. The 

material flows downhill through an air gravity conveyor. A fan on a baghouse pulls the material 

laden air through the baghouse catching any material that may be in the air stream and exhausting 

the air stream out through a filter. The baghouse is physically located between the fan and blower, 

and together the blower and fan provide the pneumatic power source for the material transfer. The 

baghouse is an integral part of the pneumatic system, and the pneumatic system requires interlocks 

between the process blower and the dust collector fan that do not allow the process to be operated 

without the dust collector. The interlocks are either hardwired between the blower and fan or the 

interlocks are maintained by an electronic Programmable Logic Controller (PLC) system.

Hardwire interlocks for a process mean that multiple pieces of equipment are wired such that the 

equipment operates together and a single switch either out in the field or in the Motor Control Center 

(MCC) triggers operation of all equipment hardwired together. If any of the equipment that is 

hardwired malfunctions, all hardwired equipment shuts down. Interlocks maintained by a PLC 

system mean that the operation of the blower and fan are controlled electronically, and the electronic 

code is written such that the operation of the blower and fan are contingent upon each other. If a 

piece of equipment that is interlocked in the PLC system shuts down, all other interlocked equipment 

shuts down. Bypassing a hardwire interlock would require rewiring of the equipment. Bypassing a 

PLC interlock would require alterations to the electronic code.

Two material handling emission units have baghouses as part of vacuum systems. The emission

into the alumina ore on the barge, and the alumina ore is sucked up for transfer to the plant. The 

blower that creates the vacuum that allows the alumina ore to be sucked off of the barge also pulls 

the material-laden air through the baghouses for river unloading catching any material that may be in 

the air stream and exhausting the air stream out through a filter. Since the vacuum system uses the 

same blower to pull material off the barge and to pull air through the dust collector, the dust

Installation ID: 143-0008 Project No. 2005-10-032

collector is an integral part of the vacuum system. If the dust collector malfunctions, the blower 

shuts off, which shuts down the entire vacuum system.

As described above, the baghouses associated with pneumatic and vacuum systems are an integral 

part of process operation. It should also be mentioned that the baghouses for these processes are 

designed to recover material that collects in the baghouse filters and return it back to downstream 

process equipment via filter blowback. The material recovery is essential for decreasing raw or inprocess material costs.

In summary, baghouses that are part of pneumatic systems or vacuum systems are inherent to the 

operation of the material transfer processes and provide for product recovery. Therefore, the 

baghouses do not meet CAM Criteria #2 (i.e. the baghouses do not meet the 40 CFR 64 definition of 

control device), and the baghouses are not subject to CAM requirements.

In addition to the pneumatic and vacuum systems, other emission units have baghouses as part of an 

in-line fluidized bed scrubber/baghouse combination that are inherent to the operation of the process. 

These in-line fluidized bed scrubber/baghouses are listed in the following table (Summary of 

Emission Units with Inherent Control Devices).

The emission points listed in the table above (Summary of Emission Units with Inherent Control 

Devices) are the stacks for the potlines and carbon anode baking processes. All of the emission units 

associated with the potlines and carbon anode baking processes emit fluorides, and the fluoride 

emissions from these processes are regulated under 40 CFR 63, Subpart LL. In order to comply with 

the fluoride emission limits established in 40 CFR 63, Subpart LL, Noranda operates in-line 

fluidized bed scrubbers/baghouses. 

The in-line fluidized bed scrubbed baghouses utilize flesh alumina ore as the fluidized bed material 

to remove fluorides in the exhaust captured from the potlines or carbon baking processes. Alumina 

ore that is fed to a potline requires the addition of fluoride to maintain the process chemistry balance. 

By sending the fresh alumina ore through the scrubbers and there by adding fluorides to the alumina 

ore prior to feeding the alumina ore to the potlines, Noranda reduces the cost for raw material 

fluoride compounds that would otherwise need to be added to the alumina ore. All of Noranda’s 
Noranda Aluminum, Incorporated Part 70 Operating Permit SB - 9

Installation ID: 143-0008 Project No. 2005-10-032

scrubbers use fresh alumina ore as the fluidized bed material. The ore that leaves the scrubber is 

referred to as reacted ore, and the reacted ore is fed to the potlines. The fresh alumina ore that is the 

fluidized bed material in the scrubbers is considered a process material, and the scrubber serves both 

as a piece of control equipment and as a piece of process equipment.

Similar to the baghouses for material transfer, the baghouses that are in-line with the fluidized bed 

scrubbers recover alumina ore and recycle ore back to the process to prevent the loss of valuable raw 

material.

In summary, the in-line fluidized bed scrubbers/baghouses are required to comply with the 40 CFR 

Part 63, Subpart LL fluoride emission limit. The scrubbers are also integral to the process operation 

in that fluorides that are necessary for the potline process chemistry balance are added to the fresh 

alumina ore in lieu of purchasing fluoride compounds to add to the fresh ore. The inline baghouses 

recover raw material back to the process. Since the in-line fluidized bed scrubbers/baghouses are 

required for compliance with a NESAHP and are an integral part of the manufacturing process, the 

in-line fluidized bed scrubbers/baghouses do not meet CAM Criteria #2 (i.e. the in-line fluidized bed 

scrubbers/baghouses do not meet the 40 CFR 64 definition of control device), and the in-line 

fluidized bed scrubbers/baghouses are therefore not subject to CAM requirements.

Based on a review of emission units that trigger all three CAM criteria, 19 baghouses are subject to 

CAM requirements. The following table provides a summary of the baghouses that trigger CAM 

requirements. Attachment D of the operating permit (Compliance Assurance Monitoring) provides a 

CAM template for the baghouses that are subject to CAM. The CAM plan was approved by the Air 

Pollution Control Program on October 31, 2007.

Greenhouse Gas Emissions

This installation is a major source for greenhouse gases. Major stationary sources are required by the 

Clean Air Act (CAA) to obtain Part 70 operating permits. While Part 70 permits generally do not 

establish new emissions limits, they consolidate applicable requirements, as defined in Missouri State 

Regulations 10 CSR 10-6.020(2)(A)23, into a comprehensive air permit. At the time of permit issuance, 

there were no applicable GHG requirements for this source. 

Note that this source is subject to the Greenhouse Gas Reporting Rule. However, the preamble of the 

GHG Reporting Rule clarifies that Part 98 requirements do not have to be incorporated in Part 70 

permits operating permits at this time. In addition, Missouri regulations do not require the installation to 

report CO2 emissions in their Missouri Emissions Inventory Questionnaire; therefore, the installation’s 

CO2 emissions were not included within this permit. The applicant is required to report the data directly 

to EPA. The public may obtain CO2 emissions data for this installation by visiting EPA’s Clean Air 

Markets website at: http://camddataandmaps.epa.gov/gdm/index.cfm.

Other Regulatory Determinations

1) 10 CSR 10-6.400, Restriction of Emission of Particulate Matter From Industrial Processes

10 CSR 10-6.400 limits the amount of particulate matter that is allowed from an emission unit, and 

is dependent on the process weight rate material processed. The emission units to which this rule 

applies are listed below. The calculations in Appendix B provide the allowable particulate emission 

rate based on 10 CSR 10-6.400 and the potential (maximum) emission rate including particulate 

emission control equipment. Process information and data used in these calculations are from the 

Part 70 Operating Permit Renewal Application, received October 14, 2005 and FIRE 6.25 - PM 

Emission Factors. If the emissions from these emission units can not violate the limits of this rule 

then evidence of this is demonstrated in Appendix B.

One of the following equations from 10 CSR 10-6.400 is used to calculate the PM allowable limit:

E = 4.10P0.67 for process weight rates up to 30 tons (60,000 lbs) per hour, and

E = 55.0P0.11– 40 for process weight rates greater than 30 tons (60,000 lbs) per hour

Where: E = rate of emission in lb/hr; and 

P = process weight rate in tons/hr (maximum hourly design rate)

2) 10 CSR 10-6.220, Restriction of Emission of Visible Air Contaminants 

Emission units EU2010, EU2030 and EU2050 are subject to two different opacity standards under 

10 CSR 10-6.220 (20% opacity limit) and 40 CFR Part 60, Subpart S (10% opacity limit). The more 

restrictive limit of 10 percent opacity shall apply. Permit Conditions EU2010-003, EU2030-003, and 

EU2050-003 establish the 10% opacity requirements as put forth in 40 CFR Part 60, Subpart S.

3) Emission Units Without Limitation:

The units listed in the ―Emission Units Without Limitations‖ section in the front of this permit either 

have no applicable regulations associated with them or are considered insignificant activities. 

The following is the list of equipment not subject to an applicable requirement identified as 

insignificant activities at the time of permit issuance. However, the installation is not limited to 

those activities listed, below.
