OAR 690-230-0040: Location of Low-Temperature Geothermal Injection Wells Not Exceeding 15,000 Gallons Per Day

(1) No low-temperature geothermal injection well with an anticipated injection rate of less than 15,000 gallons per day shall be located within 75 feet of any existing low-temperature geothermal production well utilizing the same groundwater reservoir without authorization from the Director, unless both the production and injection wells are owned or used by the same person. (2) A request to construct a low-temperature geothermal injection well within 75 feet of a low-temperature geothermal production well shall be made in writing to the Director. The request shall list the names and addresses of the property owners, street addresses of the wells, and shall state the reason(s) for locating the injection well closer than 75 feet to the production well. The Director may approve construction of an injection well closer than 75 feet to a production well only if the Director determines that the hydrologic and thermal conditions described in OAR 690-230-0110(1) justify the closer spacing.
