Description The Department of Ecology conducted an inspection of the Boise Cascade bleached kraft pulp and paper mill at Wallula, Washington, during April 1992. The mill's discharge to the Columbia River was in compliance with NPDES permit limits for five-day biochemical oxygen demand (BOD5), total suspended solids (TSS), pH, and the salmonid bioassay. A 2,3,7,8-TCDD (dioxin) concentration of 2.9 pg/L was measured in the final effluent; this is within the 10 pg/L limit that becomes effective in 1994.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
