In April 2018, the Board of County Commissioners of Kingfisher County revised its pipeline crossing permit to prohibit the use of produced water in temporary lines in Kingfisher County. The revised permit states that produced water refers to any water labeled by the Oklahoma Corporation Commission (OCC) as a deleterious substance. Deleterious substance means any chemical, salt water, oil field brine, waste oil, waste emulsified oil, basic sediment, mud or injurious substance produced or used in the drilling, development, production, transportation, refining and processing of oil, gas and/or brine mining. OAC 165:10-1. The revised permit went into effect May 1, 2018, and considering the volume of produced water in the very popular Sooner Trend, Anadarko (Basin), Canadian and Kingfisher (counties) (STACK) play, it may cause issues for operators in the area.
