review, and evaluate permit applications for discharges to water

bodies for water reuse projects. The Department shall approve such

applications as comply with the applicable rules of the

State.

B. 1. Subject to subsection A of this section, the Department

quality standards.

2. Upon initial receipt of an application for a discharge

permit that is for the purpose of developing and implementing a

water reuse project, the Department shall acknowledge to the

designated by the Oklahoma Water Resources Board as Sensitive Public
