# I. Installation Description and Equipment Listing

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

c ompany is an existing primary aluminum reduction installation but is also involved in secondary aluminum production.

Alumina (Al 2 

### O 3 

### ) is received at the plant and undergoes electrolytic reduction, known as the Hall

Heroult process, to obtain aluminum. T he 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

co ke 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 (Na 3 

### AlF 6 

### ) which also serves as the solvent for alumina. The electrolytic reduction of alumina by the carbon from the electrode forms elemental a luminum and carbon dioxide (CO 2 

### ). 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 Oper ating 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 b elow:

Monitoring : The Department of Natural Resources, Air Pollution Control Program, Compliance/Enforcement Section has approved a Compliance Assurance Mon itoring (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

a cross the filter system are selected as the CAM performance indicator s 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 baghous e 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 a nd 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 range s specified for baghouses CD

23 and CD

. 2) CAM Compliance Indicator Range : An excursion is defined as either the presence of visible emissions or as a pressure drop falls out side 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

- eva luated 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 fi le 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 wh en 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 o ther 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.

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 monito ring 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 th e 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 inc lude 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 shutdo wn 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 o r 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

The key elements of the baghouse compliance assurance m onitoring, 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

Measure ment 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 excurs ion 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

emission s‖.

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.

Verification of O perational

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 dro p 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 manufa cturer’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 th an 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

pe rformed, 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 abn ormal 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 lis ted 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 f ilter 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.

- 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 exis ting 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 b aghouse 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

Pollu tion 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 lo ng 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 ou tside 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 res ulting 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

visi ble 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 limi ts 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 investiga tion of these excursions, and, if needed, any resulting

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 TE STING 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 requir ements 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 i nfrastructure for operating and maintaining the pressure indicating devices are in place.

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

### Other Air Regulations Determine d 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 rul e 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 boil ers 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

- f ir ed boilers and process heaters. Existing small natural gas fired boile rs 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, natura l gas direct

- f ire d 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 Redu ction

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 whe re New Source Performance Standards apply (as provided in 10

CSR 10

Construction Permit Revisions

10 CSR 10

- 6.060, Construction Permi ts 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 submitte d 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 numero us 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 specificati ons; 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 i n 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 on ly 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 Operati ng 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 variou s 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.

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

Accord ing 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 locate d 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 (EU 1970 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 definiti on 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 § 63.1 500 , applicability of this subpart ,t his 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 Subp art 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.

- 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 PM 10 

### PM and PM 10 

### 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 PM 10



### . First, Noranda determined the emission units

that meet CAM applicability c riteria#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 PM 10 

### ). Second, for

units that meet CAM applicability c riteria #1

, Noranda determined the emission units that meet

CAM applicability c riteria #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 , Noran da 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 PM 10 

### limit. Appendix A p rovides a summary of the

PM and PM 10 

### emission limits that were used in the CAM applicability analysis. Since all emission units are subject to a PM and/or a PM 10 

### 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 PM 10 

### above 100

tpy. Emission units with an uncontrolled PTE for either PM or PM 10 

### greater than 100 tons per year

were reviewed to determine if the units had a control device for PM or PM 10 

### whose primary purpose was to achieve compliance with the applicable PM or PM 10 

### l imitation (CAM Criteria #2).

### 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 pro cess 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, equipme nt 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 s ections 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 A ssociated 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 flow s 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 be tween 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 th e 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.

Hard wire 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 th e 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 wo uld require alterations to the electronic code.

Two material handling emission units have baghouses as part of vacuum systems. The emission points with baghouses that are associated with vacuum systems are listed in the follo wing table ( Summary of Emission Units A ssociated with Vacuum Systems )

### The vacuum systems listed in the table above ( Summary of Emission Units A ssociated with Vacuum Systems ) are both associated with unloading of alum ina ore off the river barge. A hose is inserted 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 mat erial

- 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 t hrough the dust collector, the dust

### 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 v acuum 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 in

process 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 prod uct 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 t able ( Summary of

### 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 ca rbon 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

flui dized 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 po tline 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

### scrubbers use fresh alumina ore as the fluidized bed material. The ore that leaves the scrubber is referred to as reacted ore, and the reac ted 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 ba ghouses 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 i n 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 m anufacturing 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 a re 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. A ttachment 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 perm its. 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

pe rmits operating permits at this time. In addition, Missouri regulations do not require the installation to report CO 2 

### emissions in their Missouri Emissions Inventory Questionnaire; therefore, the installation’s

CO 2 

### emissions were not included within this p ermit. The applicant is required to report the data directly to EPA. The public may obtain CO 2 

### emissions data for this installation by visiting EPA’s Clean Air Markets website at: http://camddataandmaps.epa.gov/gdm/index.cfm.

Other Regulatory Determinati ons 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. Th e 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 equipmen t. 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 Factor s. 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 = 4.10P 0.67 

### for process weight rates up to 30 tons (60,000 lbs) per hour, and

E = 55.0P 0.11



### – 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

Emis sion 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 Condition s 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.
