The Tulsa District has four General Permits. The latest General Permit is for developments utilizing low impact developments. One RGP is associated with the construction and operation of exploration and production wells for oil, gas, and water and their supporting fills and structures. The last two General Permits authorizes work in designated Critical Resource Waters (CRWs) in Oklahoma. The CRWs currently include Outstanding Resource Waters (ORWs) and High Quality Waters (HQWs) as identified and designated in Oklahoma Water Quality Standards (OWQS), OAC 785: Chapter 45, Appendix A (July 10, 2009). The ORWs are the State Scenic Rivers and tributaries. These waters are found in the eastern portion of the State. The HQW include streams in the State that provide high quality water and aquatic habitat and most are designated as Cold Water Aquatic Community beneficial use. These HQW streams are associated with high relief areas in the State, specifically the Ozark Highlands, Boston Mountains, Ouachita Mountains, Wichita Mountains, Arbuckle Mountains, and High Plains of the Panhandle. The CRW designation may be revised in the future, and this GP would be applicable to any subsequent designation of CRWs.
