Washington state agency links Longview paper mill to September's mysterious regional odor.

The Washington State Department of Ecology reports that the Smurfit Westrock paper mill in Longview "likely contributed" to a mysterious odor that spread through southwest Washington and northwest Oregon in September. The mill vented a gas stream containing odor-causing chemicals on September 24, within its permit limits. While the agency analyzed various data, it could not confirm the mill as the sole source of the odor.
