Comparison: State vs. Federal

Rules. Oklahoma regulates state water temperatures under its general water quality standards. The state also requires that temperature be part of the state's groundwater monitoring system. Therefore, the Oklahoma water pollution control program is more stringent than the federal wastewater permit program since it regulates both surface water and groundwater. See the state section NPDES PERMIT for more information.

Administration and enforcement. DEQ's Water Quality Division administers and enforces the state's water quality program, including thermal discharge requirements. The Oklahoma Water Resources Board designates the beneficial uses of the various state waters, classifies waters of the state, and prescribes water quality standards to sustain the designated uses.
