Louisiana-Pacific (LP) Corporation Houlton Mill

1. Facility Information

Louisiana-Pacific (LP) Corporation Houlton Mill

2. Location

240 Station Road, New Limerick, Maine 04761

3. Distance from US/Canada Border

10.6 miles

4. Facility Type and Size

Engineered Wood Panel Production Facility

5. Sources of Emissions

Significant emissions sources at the LP Houlton Mill include the flake dryers, board presses, and the Central Heating Unit (CHU). The Project will include the installation of a new dryer, which will primarily direct-fire dry flake screen rejects and be equipped with a new WESP and new propane-fired RTO. The Line 2 Dryer is equipped with a dual fuel burner with a maximum heat input capacity of 135 MMBtu/hr. The Line 2 Dryer will direct fire dry flake screen rejects, propane, or a combination of both fuels. Potential emissions are based on a maximum heat input capacity of 135 MMBtu/hr, a maximum wafer throughput of 299,710 oven dried tons per year (ODT/yr), or a maximum throughput of 277,111 tons finished product per year (TFP/yr) depending on the basis of the emission factor.

6. Type of Fuel

Diesel, propane

7. Type and Quantity of Emissions

The project emissions increase is significant for PM, PM10, PM2.5, SO2, NOx, CO, VOC, CO2, HAP (from propane combustion), and GHGs. See tables below from application.

8. Emission Control Technology

• Line 2 Dryer will utilize a regenerative thermal oxidizer (RTO) and a new wet electrostatic precipitator
• Finishing Line 2 Primer Application will use of the paint booth enclosure equipped with particulate filters
• An existing and new baghouse will be used to control PM emissions from the pneumatic systems.
• Line 2 Press VOC emissions will be controlled by a new propane fired regenerative catalytic oxidizer (RCO)/RTO.
• LP is proposing the use of good combustion practices and low-NOx burners for the proposed direct-fired rotary dryer
• LP is proposing the use of low sulfur fuels for the proposed Line 2 press.
