North Pacific Paper Corporation (NORPAC)

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

Air quality source separation determination

In 2016 Weyerhaeuser and Nippon sold the NORPAC mill. In 2017, we separated the Air Operating Permit (AOP) into three permits — NORPAC, the Nippon Dynawave pulp and paper mill, and the Weyerhaeuser NR Company Longview lumber mill.

While the permits are separate, these facilities are still considered a single source of air pollution under Title V of the federal Clean Air Act. In April last year, 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 has started its public comment on this permit. Please visit SWCAAs webpage to review the permit, and provide any comments you may have to SWCAA.

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