Fiscal Year 2002 Total Maximum Daily Load (TMDL) Priority List


Public Comments Invited on Water Cleanup List:
The Washington Department of Ecology (ecology) wants your comments on a list of priority water bodies we have tentatively chosen for water cleanup planning this year. Ecology organizes water cleanup efforts through geographic areas called water quality management areas (WQMA) choosing watersheds in each of our four regions each year. To help us select which waters to cleanup, we met with groups in communities within these WQMAs in these regions last fall.

The criteria for making these selections included the severity of the pollution, potential harm to human and aquatic health, impaired beneficial uses, such as agriculture, drinking water and fish habitat, and the potential for local support for water cleanup activities. In addition, the presence of threatened and endangered fish species significantly influenced our choices.

The water cleanup list will be finalized in July. Ecology reviews and responds to your comments by August 2001.

Please address your comments on the above priority list by June 6, 2001, to Ron McBride, Ecology, P.O. Box 47600, Olympia, WA 98504-7600, rmcb461@ecy.wa.gov, phone (360) 407-6469, or fax (360) 407-6426.

The entire list of water bodies we chose from can be viewed on our website: http://www.wa.gov/ecology/wq/303d/

The following pages contain the proposed list of water bodies we plan to begin work on in 2002. The list shows each water body and the parameters of concern. The last page lists definitions of pollution problems.

*The projects shown below are the best estimate of our capacity at this time. Ecology's budget has yet to be set for the next biennium. Actual fiscal and staffing levels may result in fewer projects. In addition, as we are working in a geographic region (WRIA), projects may be expanded into additional waterbodies if we find they need work.

Definitions of Pollution Problems: Although not necessarily agents of disease, fecal coliform bacteria indicate the presence of disease-carrying organisms, which live in the same environment as the fecal coliform bacteria.

A certain minimum amount of dissolved oxygen must be present in water for aquatic life to survive.

Temperature is important because it governs the kinds of aquatic life that can live in a stream. For instance, streams must be cooler than 64 degrees Fahrenheit for salmon to successfully spawn.

pH is a term used to indicate the alkalinity or acidity of a substance as ranked on a scale from 1.0 to 14.0. Neutral pH is 7.0. Acidity increases as the pH gets lower.

PCB - Highly persistent organic chemicals used primarily in electrical equipment (e.g. transformers). Banned from production in mid-1970s. Accumulates in fish tissue.

DDT, DDE, Pesticides (Chlordane, Dieldrin, Heptachlor, Heptachlor Epoxide, Hexachlorobenzene) - Highly persistent organic chemicals. Harm aquatic organisms. Accumulate in fish tissue.

Toxics and Metals (zinc) - can persist in sediments and be present in water. Shown to have adverse effects on aquatic organisms.

Sediments - can smother fish eggs, change the aquatic organisms and habitat, and interfere with fish migration, feeding and spawning.

Phosphorus serves as a nutrient or "fertilizer" for algae and aquatic plants. Too much algae cause aesthetic problems and reduce oxygen levels in lakes and streams.
