No low-temperature geothermal injection well shall be used for injection without approval of the Director in accordance with OAR 690-210-0070. The injection plan for the proposed injection of less than 15,000 gallons per day to a low-temperature geothermal injection well will consist of a water well report from both the injection and production wells. These well reports shall be sent to the Director for review. If the injection well have not yet been constructed, or if a water well report is not available from the injection or production well, acceptable data that shall be submitted as part of the injection plan include, but are not limited to, the following: geological information of the area, depth of the well(s) in question, water well reports from nearby wells, static water level data or water quality data from the well(s) in question. After review of the well reports, or other acceptable data, the Director may require water quality testing, as per OAR 690-230-0115(1) and (2), if the Director deems it necessary. The water quality testing may be required in the situations that include, but are not limited to, injection into a groundwater reservoir that is different from the producing groundwater reservoir, or when the well is of poor construction.
