The Oklahoma Water Quality Management Plan, also called the 208 Plan after the section of the Clean Water Act that established the program, is a comprehensive document aimed at systematically managing water quality in the various watersheds within the State of Oklahoma. The Plan includes an inventory of dischargers within the State.

Changes to the 208 Plan are made from time to time as dischargers make modifications to their treatment facilities and as new facilities are constructed. Watch this area for updates to the 208 Plan.
