Weyerhaeuser Lumber Mill, Longview

Water quality penalty

Ecology issued two penalties for a total of $145,000 on July 26, 2024 against Weyerhaeuser for violating its water discharge permit.

Read the press release.

Weyerhaeuser violated its water discharge permit 36 times with its stormwater discharges between July 2022 and May 2024. Weyerhaeuser also did not monitor their stormwater discharges 15 times, did not report permit violations 16 times, and changed their stormwater system without approval.
Stormwater from Weyerhaeuser ultimately discharges to the Columbia River, which is home to many aquatic species including endangered salmon. Improperly managed stormwater can negatively impact human health and the environment.

Weyerhaeuser has 30 days to appeal the penalties to the Pollution Control Hearings Board. Water quality penalty payments to Ecology are placed into the state’s Coastal Protection Fund, which provides grants to public agencies and Tribes for water quality restoration projects.
