Weyerhaeuser Lumber Mill, Longview
We regulate the water and hazardous waste activities at Weyerhaeuser's lumber mill in Longview.
Water quality penalty
In Feb. 2022, we issued Weyerhaeuser Lumber a $40,000 penalty for water quality permit violations. The mill violated its permit 42 times for stormwater since October 2020.
The facility releasing pollution above what is allowed has the potential to impact the environment and human health. Stormwater ultimately discharges to the Columbia River, which is home to many aquatic species including endangered salmon and steelhead. When not properly managed, stormwater can carry muddy water, debris, and chemicals into local waterways. These pollutants can harm aquatic life and reduce water quality.
Weyerhaeuser has appealed the penalty to the Pollution Control Hearings Board.
Water quality penalty payments are placed into the state’s Coastal Protection Fund, which provides grants to public agencies and tribes for water quality restoration projects.
