Filter or gravel pack water supply wells may only be abandoned under a special standard. Any method of abandonment proposed must ensure that all perforated sections of the casing will be pressure grouted throughout, and that the remainder of the well is filled with cement grout. (See definition of pressure grout in OAR 690-200)
