Tacoma paper mill agrees to monetary penalty, new rules after air pollution violation

WestRock Co.’s Tacoma Mill has reached a settlement with the Washington Department of Ecology following a penalty and compliance order issued last year. The paper mill, which is on the Tacoma Tideflats along the Puyallup Waterway, was initially fined $52,000 in December 2022 for violating the company’s air quality permit.
