Current through Register Vol. 63, No. 9, September 1, 2024

(1) ASR Permit Required. On-going authorization to store and recover water injected into an aquifer requires an ASR permit. Only after completion of an ASR testing program under a limited license may an applicant apply for a permanent ASR permit.

(2) Water Right before ASR Permit. A person shall possess a water right or have a water right holder agreement which allows use of a water right for the injection source water before applying for an ASR permit. This water right shall be either a permit or certificate.

(3) Pre-application Conference. The Department requires at least one pre-application conference with a prospective permittee prior to filing an ASR permit application. The purpose of the conference is to discuss the ASR testing results, information needed for the application, and possible constraints on a project. The conference may serve as a point of review for the apparent adequacy of the applicant's hydrogeologic and other information. The Department shall invite personnel from both the DEQ and HD to the conference.

(4) Permit Application. A request for an ASR permit shall be submitted on a form provided by the Department. The application shall consist of the following:

(a) Information on, and Attachments to, the Form:

(D) Comments on Source Water/Standards. The applicant shall address the following situations as they apply:
(i) If a constituent that is regulated under OAR 333-061-0030 (ORS 448.131 and 448.273) or OAR 340-040 (ORS 468B.165) is detected in the source water, the applicant shall demonstrate that there are not other sources of water available to the applicant which would be satisfactory for injection and lower in the constituent of concern. Other sources are limited to those for which the applicant has water rights;

(ii) If a constituent is detected in the source water above 50% of the levels established under OAR 333-061-0030 (ORS 448.131 and 448.273) or OAR 340-040 (ORS 468B.165), the applicant shall install a treatment method, system or other alternative method to reduce the constituent to less than 50% of those levels, unless the applicant can show that there is not a treatment method, system or other alternative method that will reduce the level of a contaminant below the 50% level, or the lesser of:
(I) The applicant can show that it would be more costly to provide the treatment method, system or other alternative method necessary than to obtain the same amount of stored water from the next cheapest feasible water supply alternative; or

(II) In the case of a drinking water system the applicant can show the cost of adding the treatment method, system or other alternative method increases the cost per household of providing water (including operation, maintenance, and debt service for prior water projects) above 1.5% of the median household income of the community.

(iii) Notwithstanding paragraph (4)(b)(D)(ii) of this rule, in the event the applicant cannot reduce a constituent to less than the 50% level, the applicant shall minimize the constituent level by providing the level of treatment available or other alternative method which for the same amount of stored water is not as costly as either the next cheapest water supply alternative or an amount equal to that necessary to increase the cost per household of providing water to 1.5% of the median household income of the community, whichever is less;

(iv) Notwithstanding the provisions of paragraph (4)(b)(D)(i), (ii), and (iii) of this rule and after consulting with the DEQ and the HD, the Department may determine that the circumstances are such that an alternative source, treatment method, system, or other alternative method is acceptable or not necessary.

(c) Other Information. Any other information required by the Department.

(5) Permit Application Processing:
