SECTION I. GENERAL INFORMATION

The following general information is provided pursuant to ARM 17.8.1210(1).

Company Name: Plum Creek Manufacturing

Mailing Address: P.O. Box 1990

City: Columbia Falls State: Montana Zip: 59912-1990

Plant Location: Section 7 and the SW1⁄4 of Section 8, Township 30 North, Range 20 West, in Flathead 

County, Columbia Falls, Montana

Responsible Official: Tom Ray Phone: (406) 892-6200 

Facility Contact Person: Mitchell Leu Phone: (406) 892-6217 

Primary SIC Code: 2421, 2436, 2493

Nature of Business: Lumber, Plywood, Fiberboard

Description of Process: This facility produces lumber, plywood, and a medium density fiberboard 

(MDF). In addition to the sawmill, plywood plant, and MDF plant, the site includes a large wood waste 

boiler, smaller natural gas boilers, wood waste burners used to supply heat for the MDF fiber dryers, and 

one wood waste burner to heat the veneer dryer. 

The sawmill and plywood plant receive raw logs by truck. The logs are stored and sorted before being 

transferred to the sawmill for sawing into dimension lumber or to the plywood plant for peeling into 

veneer. Waste wood such as chips, sawdust, and planer shavings are transferred to the MDF plant for 

processing into fiberboard. Wood shavings and sawdust are also received from outside facilities as raw 

material for the fiberboard plant. Fugitive emissions from wood-waste transfer are controlled with 

baghouses or cyclones. Fugitive emissions from haul roads and the log deck are controlled with chemical 

dust suppressants. 

All three plants share the Riley-Union Stoker boiler as a source of process steam for operations. The 

boiler uses wood as a fuel and burns a mixture of bark, sawdust, sanderdust, and reject material from the 

plywood and fiberboard operations. The veneer dryer is heated with wood through the use of a Wellons 

wood waste cell. The exhaust gases from the Wellons unit make direct contact with the veneer and then 

exit to atmosphere through an E-tube wet electrostatic precipitator. The MDF face and core fiber dryers 

are also heated primarily with wood. Three Coen sander dust burners heat the flash-tube dryers to dry the 

wood fiber for fiberboard manufacture. The MDF face and core fiber dryer pollution control equipment 

includes long cone high-efficiency cyclones followed by four wet Electrostatic Precipitators (ESPs). The 

line 2 MDF pollution control equipment includes two Venturi scrubbers. The facility uses biofilters to 

control hazardous air pollutant (HAP) emissions to comply with 40 Code of Federal Regulations (CFR)

63, Subpart DDDD.

Compliance Demonstration

E.4. Plum Creek shall demonstrate compliance with the opacity limitations of Section III.E.1 through 

visual surveys and EPA Method 9 Tests as follows:

Plum Creek shall conduct either a semiannual Method 9 source test or a weekly visual survey of 

visible emissions on the M02-M11 Line 1 MDF Material Handling Baghouses. Under the visual 

survey option, once per calendar week, during daylight hours, Plum Creek shall visually survey 

for any visible emissions. If visible emissions are observed during the visual survey, Plum Creek 

shall conduct a Method 9 source test. The Method 9 source test shall begin within one hour of any 

observation of visible emissions. If visible emissions meet or exceed 15% opacity based on the 

Method 9 source test, Plum Creek shall immediately take corrective action to contain or minimize 

the source of emissions. If corrective actions are taken, then Plum Creek shall immediately 

conduct a subsequent visual survey (and subsequent Method 9 source test if visible emissions 

remain) to monitor compliance. The person conducting the visual survey shall record the results 

of the survey (including the results of any Method 9 source test performed) in a log, including any 

corrective action taken. Conducting a visual survey does not relieve Plum Creek of the liability 

for a violation determined using Method 9 (ARM 17.8.101(27)).

If the visual surveys are not performed once per calendar week as specified above during the 

reporting period, then Plum Creek shall perform the Method 9 source tests on the M02-M11 Line 

1 MDF Material Handling Baghouses for that reporting period. 

Method 9 source tests shall be performed in accordance with the Montana Source Test Protocol 

and Procedures Manual, except that prior notification of the test is not required. Each observation 

period must be a minimum of 6 minutes unless any one reading is 20% or greater, then the 

observation period must be a minimum of 20 minutes or until a violation of the standard has been 

documented, whichever is a shorter period of time (ARM 17.8.1213).

E.5. If any point source within the total Line 1 MDF process (M02 – M11) exceeds an applicable 

opacity limit, the Department may require all point sources in that process to be tested to 

determine compliance with mass emission limits. These tests shall conform to EPA test 

specifications under 40 CFR 60, Appendix A, including back half. PM10 tests shall conform to 40 

CFR 51, Appendix M, including back half and the Montana Source Test Protocol and Procedures 

Manual. All sources where tests are required must be equipped with stacks and sampling ports, 

with safe access for the sampling personnel. The Department may allow a total particulate test 

only in the back half is included and it is acknowledged this test can be used as a surrogate for 

PM10 (ARM 17.8.105, ARM 17.8.106, ARM 17.8.1213).

L.3. Plum Creek shall operate and shall maintain the M20, M21, M22, M23, and M24 MDF Material 

Handling baghouses (ARM 17.8.752). 

Compliance Demonstration

L.4. Plum Creek shall demonstrate compliance with the opacity limitations of Section III.L.1 through 

visual surveys and EPA Method 9 Tests as follows:

Plum Creek shall conduct either a semiannual Method 9 source test or a weekly visual survey of 

visible emissions on the M20, M21, M22, M23 and M24 – Line 2 MDF Material Handling 

Baghouses. Under the visual survey option, once per calendar week, during daylight hours, Plum 

Creek shall visually survey for any visible emissions. If visible emissions are observed during 

the visual survey, Plum Creek shall conduct a Method 9 source test. The Method 9 source test 

shall begin within one hour of any observation of visible emissions. If visible emissions meet or 

exceed 15% opacity based on the Method 9 source test, Plum Creek shall immediately take 

corrective action to contain or minimize the source of emissions. If corrective actions are taken, 

then Plum Creek shall immediately conduct a subsequent visual survey (and subsequent Method 

9 source test if visible emissions remain) to monitor compliance. The person conducting the 

visual survey shall record the results of the survey (including the results of any Method 9 source 

test performed) in a log, including any corrective action taken. Conducting a visual survey does 

not relieve Plum Creek of the liability for a violation determined using Method 9 (ARM 

17.8.101(27)).

If the visual surveys are not performed once per calendar week as specified above during the 

reporting period, then Plum Creek shall perform the Method 9 source tests on the M20, M21, 

M22, M23 and M24 - MDF Material Handling Baghouses for that reporting period. 

Method 9 source tests shall be performed in accordance with the Montana Source Test Protocol 

and Procedures Manual, except that prior notification of the test is not required. Each observation 

period must be a minimum of 6 minutes unless any one reading is 20% or greater, then the 

observation period must be a minimum of 20 minutes or until a violation of the standard has been 

documented, whichever is a shorter period of time (ARM 17.8.1213).

Plum Creek shall conduct either a semiannual Method 9 source test or a weekly visual survey of 

visible emissions. Under the visual survey option, once per calendar week, during daylight hours, 

Plum Creek shall visually survey for any visible emissions. If visible emissions are observed 

during the visual survey, Plum Creek shall conduct a Method 9 source test. The Method 9 source 

test shall begin within one hour of any observation of visible emissions. If visible emissions meet 

or exceed 15% opacity based on the Method 9 source test, Plum Creek shall immediately take 

corrective action to contain or minimize the source of emissions. If corrective actions are taken, 

then Plum Creek shall immediately conduct a subsequent visual survey (and subsequent Method 

9 source test if visible emissions remain) to monitor compliance. The person conducting the 

visual survey shall record the results of the survey (including the results of any Method 9 source 

test performed) in a log, including any corrective action taken. Conducting a visual survey does 

not relieve Plum Creek of the liability for a violation determined using Method 9 (ARM 

17.8.101(27)).

Processes

E=4.10 * P0.67 Method 5 As Required by 

the Department 

and Section 

III.A.1

Annual 

Certification

Conditions 

V.1. Plum Creek shall not cause or authorize the production, handling, transportation, or storage of 

any material unless reasonable precautions to control emissions of particulate matter are taken. 

Such emissions of airborne particulate from any stationary source shall not exhibit an opacity of 

20% or greater averaged over six consecutive minutes (ARM 17.8.308(1)).

V.2. The particulate emissions from process weight shall not exceed the value calculated by E=4.10 * 

P

0.67, where E is the rate of emissions in pounds per hour and P is the process weight rate in tons 

per hour (ARM 17.8.310).

Compliance Demonstration

V.3. Plum Creek shall demonstrate compliance with the opacity limitations of Section III.V.1 through 

visual surveys and EPA Method 9 Tests as follows:

Plum Creek shall conduct either a semiannual Method 9 source test or a weekly visual survey of 

visible emissions. Under the visual survey option, once per calendar week, during daylight hours, 

Plum Creek shall visually survey for any visible emissions. If visible emissions are observed 

during the visual survey, Plum Creek shall conduct a Method 9 source test. The Method 9 source 

test shall begin within one hour of any observation of visible emissions. If visible emissions meet 

or exceed 15% opacity based on the Method 9 source test, Plum Creek shall immediately take 

corrective action to contain or minimize the source of emissions. If corrective actions are taken, 

then Plum Creek shall immediately conduct a subsequent visual survey (and subsequent Method 

9 source test if visible emissions remain) to monitor compliance. The person conducting the 
OP2667-03 56 Date of Decision: 06/28//2011

 Effective Date: 07/29/2011

visual survey shall record the results of the survey (including the results of any Method 9 source 

test performed) in a log, including any corrective action taken. Conducting a visual survey does 

not relieve Plum Creek of the liability for a violation determined using Method 9 (ARM 

17.8.101(27)).

If the visual surveys are not performed once per calendar week as specified above during the 

reporting period, then Plum Creek shall perform the Method 9 source tests for that reporting 

period. 

Method 9 source tests shall be performed in accordance with the Montana Source Test Protocol 

and Procedures Manual, except that prior notification of the test is not required. Each observation 

period must be a minimum of 6 minutes unless any one reading is 20% or greater, then the 

observation period must be a minimum of 20 minutes or until a violation of the standard has been 

documented, whichever is a shorter period of time (ARM 17.8.1213).

V.4. As required by the Department and Section III.A.1, Plum Creek shall perform a Method 5 source 

test, or another Department approved source test method, to monitor compliance with the 

particulate emissions limit in Section III.V.2. The test methods shall be conducted in accordance 

with the Montana Source Test Protocol and Procedures Manual (ARM 17.8.106 and ARM 

17.8.1213). 

Recordkeeping 

V.5. If weekly visual surveys are performed, Plum Creek shall maintain, on-site, a log including all 

visual observations monitoring compliance with the visual survey requirement. The log shall 

include the required information, the date, the time, and the initials of the documenting personnel 

(ARM 17.8.1212).

V.6. All compliance source test recordkeeping shall be performed in accordance with the test method 

used and the Montana Source Test Protocol and Procedures Manual, and shall be maintained on 

site. The reports must be submitted in accordance with the Montana Source Test Protocol and 

Procedures Manual except that any Method 9 source test reports shall be maintained on-site and 

shall be submitted to the Department only upon request (ARM 17.8.106 and ARM 17.8.1212).

Reporting

V.7. All source test report(s) shall be submitted to the Department in accordance with the Montana 

Source Test Protocol and Procedures Manual except that any Method 9 source test reports shall 

be maintained on-site and shall be submitted to the Department only upon request (ARM 

17.8.1212).

V.8. The annual compliance certification required by Section V.B must contain a certification 

statement for the above applicable requirements (ARM 17.8.1212). 

V.9. The semiannual compliance monitoring reports shall provide (ARM 17.8.1212): 

a. If weekly visual surveys are performed during the reporting period, a summary of the 

results contained in the weekly visual observations log; and

b. A summary of results of any source testing that was performed during the reporting 

period.

SECTION V. GENERAL PERMIT CONDITIONS

A. Compliance Requirements

ARM 17.8, Subchapter 12, Operating Permit Program §1210(2)(a)-(c)&(e), §1206(6)(c)&(b)

1. The permittee must comply with all conditions of the permit. Any noncompliance with the 

terms or conditions of the permit constitutes a violation of the Montana Clean Air Act, and may 

result in enforcement action, permit modification, revocation and reissuance, or termination, or 

denial of a permit renewal application under ARM Title 17, Chapter 8, Subchapter 12.

2. The filing of a request by the permittee for a permit modification, revocation and reissuance, or 

termination, or of a notification of planned changes or anticipated noncompliance does not stay 

any permit condition.

3. It shall not be a defense for a permittee in an enforcement action that it would have been 

necessary to halt or reduce the permitted activity in order to maintain compliance with the 

conditions of the permit. If appropriate, this factor may be considered as a mitigating factor in 

assessing a penalty for noncompliance with an applicable requirement if the source 

demonstrates that both the health, safety or environmental impacts of halting or reducing 

operations would be more serious than the impacts of continuing operations, and that such 

health, safety or environmental impacts were unforeseeable and could not have otherwise been 

avoided.

4. The permittee shall furnish to the Department, within a reasonable time set by the Department 

(not to be less than 15 days), any information that the Department may request in writing to 

determine whether cause exists for modifying, revoking and reissuing, or terminating the 

permit, or to determine compliance with the permit. Upon request, the permittee shall also 

furnish to the Department copies of those records that are required to be kept pursuant to the 

terms of the permit. This subsection does not impair or otherwise limit the right of the 

permittee to assert the confidentiality of the information requested by the Department, as 

provided in 75-2-105, MCA.

5. Any schedule of compliance for applicable requirements with which the source is not in 

compliance with at the time of permit issuance shall be supplemental to, and shall not sanction 

noncompliance with, the applicable requirements on which it was based.

6. For applicable requirements that will become effective during the permit term, the source shall 

meet such requirements on a timely basis unless a more detailed plan or schedule is required by 

the applicable requirement or the Department.

B. Certification Requirements

ARM 17.8, Subchapter 12, Operating Permit Program §1207 and §1213(7)(a)&(c)-(d)

1. Any application form, report, or compliance certification submitted pursuant to ARM Title 17, 

Chapter 8, Subchapter 12, shall contain certification by a responsible official of truth, accuracy 

and completeness. This certification and any other certification required under ARM Title 17, 

Chapter 8, Subchapter 12, shall state that, based on information and belief formed after 

reasonable inquiry, the statements and information in the document are true, accurate and 

complete.
OP2667-03 59 Date of Decision: 06/28//2011

 Effective Date: 07/29/2011

2. Compliance certifications shall be submitted by February 15 of each year, or more frequently if 

otherwise specified in an applicable requirement or elsewhere in the permit. Each certification 

must include the required information for the previous calendar year (i.e., January 1 –

December 31).

3. Compliance certifications shall include the following:

a. The identification of each term or condition of the permit that is the basis of the 

certification;

b. The identification of the method(s) or other means used by the owner or operator for 

determining the status of compliance with each term and condition during the certification 

period, consistent with ARM 17.8.1212;

c. The status of compliance with each term and condition for the period covered by the 

certification, including whether compliance during the period was continuous or 

intermittent (based on the method or means identified in ARM 17.8.1213(7)(c)(ii), as 

described above); and

d. Such other facts as the Department may require to determine the compliance status of the 

source.

4. All compliance certifications must be submitted to the Environmental Protection Agency, as 

well as to the Department, at the addresses listed in the Notification Addresses Appendix of this 

permit.

C. Permit Shield

ARM 17.8, Subchapter 12, Operating Permit Program §1214(1)-(4)

1. The applicable requirements and non-federally enforceable requirements are included and 

specifically identified in this permit and the permit includes a precise summary of the 

requirements not applicable to the source. Compliance with the conditions of the permit shall 

be deemed compliance with any applicable requirements and any non-federally enforceable 

requirements as of the date of permit issuance.

2. The permit shield described in 1 above shall remain in effect during the appeal of any permit 

action (renewal, revision, reopening, or revocation and reissuance) to the Board of 

Environmental Review (Board), until such time as the Board renders its final decision.

3. Nothing in this permit alters or affects the following:

if the inclusion of a RACT into the permit pursuant to ARM Title 17, Chapter 8, 

Subchapter 12, is appealed to the Board, the permit shield, as it applies to the source’s 

existing permit, shall remain in effect until such time as the Board has rendered its final 

decision.

4. Nothing in this permit alters or affects the ability of the Department to take enforcement action 

for a violation of an applicable requirement or permit term demonstrated pursuant to ARM 

17.8.106, Source Testing Protocol.

5. Pursuant to ARM 17.8.132, for the purpose of submitting a compliance certification, nothing in 

these rules shall preclude the use, including the exclusive use, of any credible evidence or 

information relevant to whether a source would have been in compliance. However, when 

compliance or noncompliance is demonstrated by a test or procedure provided by permit or 

other applicable requirements, the source shall then be presumed to be in compliance or 

noncompliance unless that presumption is overcome by other relevant credible evidence.

6. The permit shield will not extend to minor permit modifications or changes not requiring a 

permit revision (see Sections I & J).

7. The permit shield will extend to significant permit modifications and transfer or assignment of 

ownership (see Sections K & O).

2. An emergency constitutes an affirmative defense to an action brought for noncompliance with a 

technology-based emission limitation if the permittee demonstrates through properly signed, 

contemporaneous logs, or other relevant evidence, that:

a. An emergency occurred and the permittee can identify the cause(s) of the emergency;

b. The permitted facility was at the time being properly operated;

c. During the period of the emergency the permittee took all reasonable steps to minimize 

levels of emissions that exceeded the emission standards or other requirements in the 

permit; and 

d. The permittee submitted notice of the emergency to the Department within 2 working days 

of the time when emission limitations were exceeded due to the emergency. This notice 

fulfills the requirements of ARM 17.8.1212(3)(c). This notice must contain a description 

of the emergency, any steps taken to mitigate emissions, and corrective actions taken.

3. These emergency provisions are in addition to any emergency, malfunction or upset provision 

contained in any applicable requirement.

G. Inspection and Entry

receipt of the notice, unless the fee assessment is appealed pursuant to ARM 17.8.511. If any 

portion of the fee is not appealed, that portion of the fee that is not appealed is due 30 days after 

receipt of the notice. Any remaining fee, which may be due after the completion of an appeal, 

is due immediately upon issuance of the Board’s decision or upon completion of any judicial 

review of the Board’s decision.

3. If the permittee fails to pay the required fee (or any required portion of an appealed fee) within 

90 days of the due date of the fee, the Department may impose an additional assessment of 15% 

of the fee (or any required portion of an appealed fee) or $100, whichever is greater, plus 

interest on the fee (or any required portion of an appealed fee), computed at the interest rate 

established under 15-31-510(3), MCA.

Table I

A. General Criteria

Indicator DESP Voltage

Measurement Approach Voltage Meter. A permanent voltage meter measures the secondary voltage for 

each of the 4 fields of the DESP

Indicator Range An excursion is defined as an hourly average of less than 24.9 kV. There is no 

upper limit for voltages for excursions. An excursion triggers an 

inspection/investigation, corrective action, and a reporting requirement. 

B. Performance Criteria

Data Representativeness The voltmeter is part of the DESP instrumentation. It has long been known 

and accepted that low secondary voltage in the fields is indicative of a 

malfunction. The field’s collection efficiency decreases as the voltage 

decreases within the unit’s operating range. In addition, there is no bypass 

present between the boiler and DESP; therefore, all emissions must route 

through the DESP.
