Nippon Dynawave, Longview

We regulate the air, water, and hazardous waste activities at the Nippon Dynawave Packaging Company pulp and paper mill in Longview. On Sept. 1, 2016, Nippon bought this mill from Weyerhaeuser.

Air quality: Proposed changes to extruders operation permit limits

Comment period: June 10 – July 11, 2019
We invite you to comment on proposed Notice of Construction (NOC) order 16181, the associated State Environmental Policy Act (SEPA) Determination of Nonsignificance, and changes to the mill's Air Operating Permit.

This would increase some permit limits, allowing increases in some air pollutants, at Nippon Dynawave's extruders operations. The extruders apply a polymer to the surface of paperboard to make liquid packaging containers (such as milk cartons and paper cups). No physical change to the extruders operation is included in the project.

Read the public comment notice for information on how to make comments. Read the project application, support document, and SEPA checklist for more information on the project.

Air quality impacts
The changes allow the following air pollutant (emission) limits to increase.

  • PM above 10 microns in size (PM10) by 1 pound/hour (lb/hr)

  • PM2.5 by 0.1 lb/hr

  • Volatile organic compounds by 4.5 lb/hr, 19.7 tons/year

As long as all applicable requirements are met, these increases are allowed under air quality laws, rules, and regulations.

Water quality permit

The comment period on Nippon Dynawave's draft updated National Pollutant Discharge Elimination System (NPDES) water quality permit ended May 28, 2019. This removes requirements related to the regulation of water quality of North Pacific Paper Corporation (NORPAC) and the Weyerhaeuser lumber mill/log yard. 

Currently, the three mills 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. We do not propose changing any of Nippon's requirements under its water quality permit, nor do we propose allowing any increase in pollution.

We also accepted comment on the new NORPAC and Weyerhaeuser permits. Read the comment notice, and visit the proposed permits page for more information.

Air quality: Pulp dryer project

We finalized notice of construction (NOC) order 16197 on May 16, 2019. This allows Nippon Dynawave to build a new piece of equipment called a pulp dryer. The pulp dryer will allow the mill to dry up to 525 air-dried metric tons of pulp each day.

Facility information

This is a kraft pulp and paper mill and liquid packaging plant.
