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.

Water quality: Permit changes

Comment period: April 25 – May 28, 2019
We invite you to comment on Nippon Dynawave's draft updated National Pollutant Discharge Elimination System (NPDES) water quality permit. This would remove 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're also accepting 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

Comment period: April 3 – May 10, 2019
We invite you to comment on proposed notice of construction (NOC) order 16197. This would allow Nippon Dynawave to build a new piece of equipment called a pulp dryer. The pulp dryer would allow the mill to dry up to 525 air-dried metric tons of pulp each day.

Read the public comment notice for information on holding a public event and how to make comments.
