The Oklahoma Water Resources Board proposed to amend Okla. Admin. Code §§785:35-7-1 and 785:35-7-1.1, and adopt §785:35-7-3. The proposed amendments and adoption would prohibit construction of fresh groundwater wells in marginal-quality water zones to protect against contamination of fresh groundwater, add a provision identifying and referencing industry standards for the plugging of vertical closed loop heat exchange wells, and provide minimum construction standards for marginal water wells. A hearing will be held January 15, 2019, and comments are due that same date.
