OAR 690-217-0020: Requirements for Pump Tests

(1) For water right applications received on or after December 20, 1988, a pump test as described in OAR 690-217-0005 to 690-217-0055 is required before a certificate of water right will be issued. The results of the test shall be submitted on the pump test report form. (2) For water right permits or certificates with priority dates before December 20, 1988, a pump test as described in OAR 690-217-0005 to 690-217-0055 and subsequent pump test requirements every ten years shall be waived unless required by the Director. The Director may require pump tests as provided in ORS 537.772 in specific cases or areas as determined to be necessary. Such areas may include, but are not limited to, critical ground water areas or serious water management problem areas as defined in OAR 690-085-0020. (3) If a landowner owns multiple wells producing from the same aquifer and has tested one of those wells, he may request exemptions for all other of those wells which are within five miles of the tested well and which produce water from the same aquifer. If a well is more than five miles from the tested well, or produces from a different aquifer, it must be tested separately. Requests for exemptions shall be in writing and include water well reports or other documentation showing the water producing zones for each well. (4) In cases where a well provides the source of water for more than one water right permit or certificate, it shall be indicated on the pump test report that the pump test applies to multiple water rights. The permit or certificate numbers of all the water rights the pump test applies to shall be listed on the pump test report.
