Description In October 1988 EPA released an interim strategy to regulate dioxin discharging from mills on the lower Snohomish River. In June 1989 WA Dept. of Ecology listed 8 pulp mills as violating WQ standards, including Weyerhaeuser Paper Company in Everett. This total maximum daily load (TMDL) was developed to set wasteload allocations (WLAs) for the dioxin being discharged into the river. These WLAs were incorporated into NPDES permits for the Weyerhaeuser mill. Ecology submitted the TMDL to EPA, and they approved the TMDL in September 1992.
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.
