5.2.  ESP Monitoring Plan

The permitte must maintain a monitoring plan for the ESP and must monitor the operation of the ESP in accordance with the plan.

5.3.  Boilers Oxygen Monitoring

The permittee must monitor the performance of Boilers 1 and 2 and associated pollution control devices in accordance with the following conditions:

i.  For each boiler, the permittee must calibrate, operate, maintain, and record the output of a continuous excess oxygen monitor in accordance with the manufacturer’s written instructions. Real time data must be displayed/recorded at least once every minute that the boiler is in operation. Hourly averages of the data must be recorded once each clock hour that the boiler is in operation. The minimum data availability shall be 75% of the operating hours per day for 90% of the operating days per calendar quarter. . Monitor availability must be determined excluding periods of calibrations and routine maintenance.

ii.  The permittee must maintain excess oxygen levels within the range of 4% to 14% except during periods of boiler startup and shut down. The permittee must record any instance in which the excess oxygen level is found outside this range and take immediate corrective action to return the boiler(s) to efficient operation. Operation outside the identified range is not considered a violation in itself if corrective action is immediately taken to restore the boiler(s) to efficient operation. The corrective action taken must be identified and recorded in a boiler operating log.

iii.  The permittee may establish a revised excess oxygen action level with written approval by the Department.

iv.  The permittee must maintain a log of the types and amounts of wood based fuel burned.

Monitoring Requirements

The permittee must inspect, monitor, and maintain records of the operation and maintenance of the plant and associated air contaminant control devices to report to the Department for the following parameters and information:

b.  All operating and production parameters used to calculate the plant site emissions as required by Condition 0 and 5.6 to determine compliance with Condition 4.1.

Operating Parameters:

i.  MBF/month of Douglas fir processed through the dry kilns.

ii.  MBF/month of Hemlock and Spruce processed through the dry kilns.

iii.  Steam production of the boilers (lbs/month)

d.  Records of major maintenance to the air contaminant control systems or any changes to the process that took place (record on occurrence).

5.4.  PSEL Compliance Monitoring

Compliance with the PSEL must be calculated monthly and is determined for each 12-consecutive calendar month period based on the following calculation for each pollutant:

E  =  S(EF x P)/2000 lbs

where,

E  =  pollutant emissions (ton/yr);

EF  =  pollutant emission factor (see Condition 13.0);

P  =  process production (see Condition 14.0)

5.5.  VOC PSEL Compliance Monitoring

Annual VOC emissions for each 12 consecutive calendar month period must be calculated monthly by the following formula:

 E_VOC-A =  å[E_VOC-MB + E_VOC-B/K] x 1 ton/2000 lb

E_VOC-MB =  [å(C_X * D_X * K_X) – W]

 E_VOC-B/K =  Boiler/Kiln VOC emissions determined in

     Condition 5.5.

Where,

E_VOC-A   =  Annual VOC emissions in tons

E_VOC-MB =  Mass balance

E_VOC-B/K =  Boiler/kiln

C   =  Material usage for the period in gallons

D   =  Material density in pounds per gallon

K   =  VOC concentration expressed as a decimal

X   =  Subscript x represents a specific material

W   =  Weight of VOC shipped offsite

5.6.  Emission Factors

The permittee must use the emission factors provided in Condition 13.0 for calculating pollutant emissions, unless alternative emission factors are approved by the Department. The permittee may request or the Department may require using alternative emission factors provided they are based on actual test data or other documentation (e.g., AP-42 compilation of emission factors) that has been reviewed and approved by the Department.

6.1.  Small Quantities Sawdust

Small quantities (less than 200lbs/month) of sawdust used to soak up oil spills may be burned in the fuel boiler. Emissions from the estimated 10 gallons of oil burned per year would be less than emissions from burning wood and therefore are conservatively addressed by treating them as if they were from burning wood.

6.2.  Dry Kilns

The Permittee is prohibited from operating the dry kilns for production drying at a temperature > 200º Fahrenheit unless a higher temperature is approved by the Department.

7.1.  Operation and Maintenance
