The Oklahoma Water Resources Board (OWRB) is proposing to amend provisions of Oklahoma's Water Quality Standards and Implementation of Oklahoma's Water Quality Standards codified in Oklahoma Administrative Code 785:45 and 785:46. The proposed changes are summarized below. The proposed revision to the Scenic River reaches of Illinois River, Flint Creek, and Barren Fork Creek total phosphorus criterion modifies the criterion duration and frequency based on new and reexamined scientific information. The revision to the total phosphorous criterion requires related changes to the state’s beneficial use assessment protocols to effectively implement the revised criterion in monitoring and assessment programs. The updated use assessment protocols address elements such as data requirements, procedures, and test for beneficial use support.
Additionally, a new “critical condition” requirement for water quality monitoring and assessment is proposed. The critical condition requirement establishes a baseflow threshold that will limit the total phosphorus data that can be used for assessment of the aesthetics beneficial use in the Scenic River reaches of Illinois River, Flint Creek, and Barren Fork Creek.
Copies of the proposed water quality standard revision and supporting technical documentation can be obtained from the OWRB website at: http://www.owrb.ok.gov/ These documents may also be requested from Rebecca Veiga Nascimento, Water Quality Standards Program Manager at Rebecca.Veiga@owrb.ok.gov or 405-530-8952.
