(2) Upon determining that an application contains the information listed under OAR 690-077-0020(4) and is complete and not defective, the Department shall endorse on the application the date upon which the application was received for filing at the Department, which shall be the priority date for any water right issued in response to the application. All applications that comply with the provisions of law shall be recorded in a suitable book kept for that purpose. For the purposes of this section, a suitable book shall include the Department’s electronic water rights information system.

If the proposed use is prohibited, the Department shall return the application with an explanation of the reason for the return.
