OAR 340-040-0190: Wellhead Protection: Update Procedure

(1) A Wellhead Protection Plan must be recertified every five years from the date of prior Department certification. (2) Recertification of the present Plan can take place if all the following conditions apply: (a) No conditions that could potentially modify the boundaries of the Wellhead Protection Area have occurred; (b) An updated inventory is completed and submitted which shows that no new potential sources of contamination have moved into the Wellhead Protection Area which are not addressed in the existing Plan; (c) The management practices outlined in the existing Plan are still appropriate and being implemented; (d) The existing contingency element in the Plan is still relevant; and (e) All signatories to the existing Plan agree to recertify the Plan by signing the recertification request letter. (3) If a certified Plan cannot meet the conditions under section (2) of this rule, then a revised Wellhead Protection Plan must be resubmitted for certification.
