Comment period: April 25 – May 28, 2019
We invite you to comment on the draft National Pollutant Discharge Elimination System (NPDES) water quality permit for Weyerhaeuser NR Company's lumber mill and log yard in Longview.
Currently, North Pacific Paper Corporation (NORPAC), Nippon Dynawave, and this mill operate under one permit because they used to have common ownership under Weyerhaeuser. Weyerhaeuser sold the two pulp and paper mills, and we need to separate the permit into one for each facility.
The draft permit:
- Separates Weyerhaeuser's requirements from the Nippon Dynawave permit.
- Changes the stormwater outfall limits and benchmarks.
- Adds limits to process wastewater.
We're also accepting comment on the new NORPAC and updated Nippon permits. Read the comment notice and visit the proposed permits page for more information.
While this mill, NORPAC, and Nippon Dynawave have separate air operating permits (AOPs), these facilities are still considered a single source of air pollution under Title V of the federal Clean Air Act. In April 2018, we asked the public for input on the proposed decision that the facilities should be considered three separate major sources for Title V permitting.
A result of that decision would be to transfer air quality regulatory authority for this facility, including its AOP, to the Southwest Clean Air Agency (SWCAA).
SWCAA held a public comment on its draft permit and is working to finalize it. Please visit SWCAA's webpage for more information.
We determined that when this permit is final, the lumber mill will be a separate major source for air pollution (pdf) under Title V. SWCAA will regulate air quality at the facility, while we will continue to regulate water quality and hazardous waste activities.
This is a lumber mill and log export facility. It sends wastewater to the Nippon Dynawave pulp and paper mill for treatment. The mill then sends the treated wastewater to the Columbia River.
