Washington State’s 1998 303(d) List superseded the 1996 List. However, the 1996 List remains an important yardstick for tracking state progress in accomplishing water cleanup plans (TMDLs).

In 1991 the NW Environmental Advocates and the NW Environmental Defense Center sued EPA and Ecology over the slow pace of conducting TMDL studies and working to remove waters from the 303(d) List. A consent decree, signed into effect in 1998 between EPA and the environmental groups, used the 1996 List as the basis for scheduling TMDL work over the following 15 years. Ecology and EPA signed a Memorandum of Agreement as part of the consent decree committing Ecology to addressing 1,576 TMDLs on 666 waterbodies as listed in the 1996 303(d) List.
