- Distance from U.S./Canada border:
Facility is approximately 85 km from the U.S./Canada border.
- Type and size of Facility:
Facility consists of three plants all located at the same site: the
sawmill, the plywood mill, and the medium density fiberboard (MDF)
plant.
Input capacity of wood-fired Stoker boiler is 292.4 MMBtu/hr.
Three natural gas-fired boilers with design capacities of 20,000,
10,500, and 22,500 lbs/hr of steam.
- Source of Emissions:
2 MDF fiber dryers, two plywood veneer dryers, a wood-fired boiler,
three gas-fired boilers, various baghouses from the plywood process
and the MDF process, many planer, plywood, and MDF cyclones, fugitive
dust from mill vehicles and log yard activity.
- Type of Fuel:
Wood waste and natural gas.
- Type and Quantity of Emissions:
Emission increases due to modification:
Modification is major for CO only, thus only the CO emissions
need to be addressed in the BACT analysis. Modification consists
of an increase in the allowable CO emissions from the wood-fired
Stoker boiler from 100 lbs/hr to 468 lbs/hr, due to an outdated
emission factor. Actual CO emissions would not change. Area is nonattainment
for PM-10.
- Emission Control Technology:
No additional controls for the Stoker boiler.
- Date Permit Application Received:
Permit application is dated May 19, 1995 from the State of Montana
and was received by Region VIII on May 23, 1995. State of Montana
issued the final construction permit on July 26, 1995. Permit #2667-07.
