North Pacific Paper Corporation (NORPAC)

We regulate the air, water, and hazardous waste activities at the NORPAC paper mill in Longview.

Water quality

Comment period: April 25 – May 28, 2019
We invite you to comment on the North Pacific Paper Corporation (NORPAC) draft National Pollutant Discharge Elimination System (NPDES) water quality permit. 

Currently, NORPAC, Nippon Dynawave, and Weyerhaeuser NR Company's lumber mill/log yard 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 NORPAC's requirements from the Nippon Dynawave permit.
  • Adds limits to process wastewater and benchmarks to stormwater.

We're also accepting comment on the new Weyerhaeuser and updated Nippon permits. Read the comment notice and visit the proposed permits page for more information.

Air quality

While NORPAC, Nippon Dynawave, and Weyerhaeuser NR Company's lumber mill/log yard 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 NORPAC, 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 SWCAAs webpage for more information.

We determined that when this permit is final, NORPAC will be a separate major source for air pollution (pdf). SWCAA will regulate air quality at the facility, while we will continue to regulate water quality and hazardous waste activities.

Facility information

NORPAC makes newsprint, printing, and specialty papers out of thermomechanical pulp, deinked pulp from recycled newsprint, and bleached kraft pulp from the Nippon Dynawave pulp and paper mill.

It sends wastewater to the Nippon mill for treatment. The mill then sends the treated wastewater to the Columbia River.
