2006 Revision of Clean Water Act Section 303(d) List of Water Quality Limited Segments |

| Under Section 303(d) of the Clean Water Act, states, territories, and authorized tribes are required to develop a list of water quality limited segments. The waters on the list do not meet water quality standards, even after point sources of pollution have installed the minimum required levels of pollution control technology. The law requires for waters on the list that priority rankings be established for the development of action plans, called Total Maximum Daily Loads (TMDLs), to improve the water quality. Board-Approved 2006 Clean Water Act Section 303(d) List of Water Quality Limited Segments The following documents contain the draft list of waters and pollutants that still need TMDLs. This portion of the list is required by section 2.1 of the Listing Policy.

This portion of the list is required by section 2.2(1) of the Listing Policy. List of Water Quality Limited Segments Being Addressed By Action Other Than TMDLs This portion of the section 303(d) list contains those waters and pollutants where the water quality problem is being addressed by an action other than a TMDL and water quality standards are not yet met.
