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 Pollution Source Separation Determination

Comment period: April 11 - May 11, 2018
We invite you to comment on the preliminary air pollution Source Separation Determination for the Nippon Dynawave, North Pacific Paper Company (NORPAC), and Weyerhaeuser NR Co. facilities located in Longview. 

  • Nippon operates a kraft pulp and paper mill.
  • NORPAC operates a thermomechanical pulp and paper mill.
  • Weyerhaeuser operates a lumber mill.
Weyerhaeuser formally owned the kraft and lumber mills and was a co-owner of NORPAC. These facilities operated under a single air operating permit (AOP).  After Weyerhaeuser sold the kraft mill and NORPAC facility in fall of 2016, we held comment periods, separating the Air Operating Permit into three separate permits.
  • Currently, the three facilities are still considered a single source of air pollution under Title V of the Clean Air Act.
  • We propose separating the facilities into three separate sources of air pollution.
Read the proposed determination and comment period notice for more information.
