Ecology recognizes that communities do not have to wait for a formal TMDL planning process and can grab the initiative to create programs to clean up polluted waters. Because these programs are locally controlled, there is an opportunity to reduce overall costs and for the communities to exert greater control over the cleanup process.
Category 4b - has a pollution control program: water bodies that have a program in place that is expected to solve the pollution problems. While pollution control programs are not TMDLs, they must have many of the same features and there must be some legal or financial guarantee that they will be implemented.
Several programs have been accepted by Department of Ecology and the Environmental Protection Agency as qualifying as 4b programs. Accordingly, the Category 5 waters in these programs have been removed from Category 5 (on the 303(d) List) to Category 4B. A write-up of these programs follows:
