Nature of Business: Lumber, Plywood, Fiberboard

Description of Process: This facility produces lumb er, 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

on e 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

venee r. 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 f rom 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 g ases 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 f lash

- 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 )

E.4. Plum Creek shall demonstrate compliance with the opacity limitati ons 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 e missions. 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 o ne 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 proc ess (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.

### 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 mu st route through the DESP. Verification of Operational
