North Pacific Paper Corporation (NORPAC)

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


Water quality

The comment period on the North Pacific Paper Corporation (NORPAC) draft National Pollutant Discharge Elimination System (NPDES) water quality permit ended May 28, 2019, and we're working to finalize the 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 also accepted comment on the new Weyerhaeuser and updated Nippon permits. Read the comment notice and visit the proposed permits page for more information.

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.

Permit information

The Southwest Clean Air Agency regulates the mill's air quality activities. Visit the Southwest Clean Air Agency website or call 360-574-3058 for more information.
