Fish Passage Approval
(1) No person shall construct or maintain any artificial obstruction across any waters of this state that are inhabited, or were historically inhabited, by native migratory fish without providing passage for native migratory fish.
(2) Prior to construction, fundamental change in permit status or abandonment of an artificial obstruction in any waters of this state, a person owning or operating an artificial obstruction shall obtain a determination from the Department as to whether native migratory fish are or were historically present in the waters, unless the owner or operator assumes the presence of native migratory fish.
(3) If the Department determines, or the owner or operator assumes, that native migratory fish are or were historically present in the waters, prior to construction, fundamental change in permit status, or abandonment of the artificial obstruction the person owning or operating the artificial obstruction shall either:
(a) Obtain from the Department an approval determination of a fish passage plan that meets the requirements of OAR 635-412-0035 for the specific artificial obstruction.
(b) Obtain from the Department a programmatic approval of a fish passage plan for multiple artificial obstructions of the same type. The Department may also grant programmatic approval to an agent for multiple owners or operators of artificial obstructions of the same type. Programmatic approvals are only valid so long as the owner or operator complies with the conditions of the programmatic approval. The Department shall only provide programmatic approval if:
(A) Fish passage structures placed under the programmatic approval meet criteria determined by the Department;
(B) The owner, operator, or agent demonstrates to the Department prior experience providing or approving acceptable fish passage structures;
(C) The owner, operator, or agent reports installation information annually to the Department, including but not limited to the location and installation date of all fish passage structures placed under the programmatic approval;
(D) The owner or operator allows, or the agent requires owners or operators to allow, the Department to inspect fish passage structures placed under the programmatic approval at reasonable times; and
(E) The owner, operator, or agent agrees to expeditiously remedy all fish passage structures placed under the programmatic approval which the Department finds do not meet the criteria or conditions of the programmatic approval.
(c) Pursuant to ORS 527.710(6), install and maintain road-stream crossing structures on non-federal forestlands in compliance with State Board of Forestry, through the Oregon Department of Forestry, rules and guidelines. These rules and guidelines require concurrence by the Oregon Department of Fish and Wildlife that they meet the purposes of the Department's fish passage program;
(d) Obtain a waiver from fish passage requirements for the artificial obstruction as provided in OAR 635-412-0025; or
(e) Obtain an exemption from fish passage requirements for the artificial obstruction as provided in OAR 635-412-0025.
(4) Fish passage plans shall provide for and be implemented such that fish passage is installed at the artificial obstruction prior to completion of or by the end of the same in-water work period as the action which triggered fish passage requirements under subsection (2), unless:
(a) An owner or operator demonstrates to the Department an imminent or immediate threat to human safety which requires construction at a failed artificial obstruction prior to being able to complete the requirements of subsection (3), and the Department approves a fish passage plan in which the requirements of subsection (3) shall be met by the end of the next in-water work period or as soon as practicable. Providing passage at the time of construction is preferred;
(b) The Commission finds that additional time is necessary and appropriate given the size and scope of the project;
(c) Installation begins within this period and the Department finds that additional time to complete installation is necessary and appropriate given the size and scope of the project; or
(d) The Department finds that additional time is necessary and appropriate as part of the terms and conditions of a negotiated settlement for a federal proceeding, or in coordination with other federal requirements.

Fish Passage Waivers and Exemptions
(1) Waivers from fish passage requirements shall be granted for an artificial obstruction if the Commission (or Department, as applicable) determines that mitigation rather than fish passage proposed by the person owning or operating the artificial obstruction provides a net benefit to native migratory fish.
(2) Net benefit to native migratory fish is determined by comparing the benefit to native migratory fish that would occur if the artificial obstruction had fish passage to the benefit to native migratory fish that would occur using the proposed mitigation. To qualify for a waiver of the requirement to install fish passage, mitigation shall result in a benefit to fish greater than that provided by the artificial obstruction with fish passage. The net benefit to fish determination shall be based upon conditions that exist at the time of comparison.
(3) Waivers shall be valid so long as the owner or operator continues to provide the agreed-upon mitigation measures and until the waived artificial obstruction undergoes further construction, a fundamental change in permit status, or abandonment.
(4) The Commission (or Department as applicable) may grant exemptions from fish passage requirements at an artificial obstruction if it is determined that:
(a) A lack of fish passage has been effectively mitigated;
(b) The owner or operator has received a legal waiver for the artificial obstruction from the Commission or the Department; or
(c) There is no appreciable benefit to providing fish passage.
(5) For exemptions granted under subsection (4)(a) and (4)(b), the exemption continues only so long as the original benefit of the mitigation is maintained.
(6) The Commission shall review, at least once every seven years, exempt artificial obstructions that do not have exemption expiration date to determine whether the exemption should continue. The Commission may revoke or amend an exemption if it finds that circumstances have changed such that the basis for the exemption no longer applies. An exemption granted as a result of an action which triggered fish passage requirements under OAR 635-412-0020(2) tolls the trigger event until the exemption is revoked.
(7) To obtain a waiver or an exemption from fish passage requirements, an owner or operator of an artificial obstruction shall obtain from and submit to the Department an application for the waiver or exemption.
(8) Based on application review, verification and site-specific knowledge, Department staff shall provide a written benefit analysis of whether the waiver request meets the requirements of subsection (1) or the exemption request meets the requirements of subsections (4) and (5). If there is some level of fish passage at the artificial obstruction, but it does not meet the requirements of OAR 635-412-0035, that passage shall be factored into the Department's net benefit analysis, allowing a reduction in required mitigation.
(9) To receive a waiver, or an exemption under subsection (4)(a), an owner or operator of an artificial obstruction shall enter an agreement with the Commission (or Department as applicable) that clearly describes timelines, duties, responsibilities, and options regarding the mitigation. The agreement shall state that the mitigation shall be completed prior to completion of or by the end of the same in-water work period as the action which triggered fish passage requirements under OAR 635-412-0020(2), unless the Commission finds that additional time is necessary and appropriate:
(a) Given the size and scope of the project; or
(b) To coordinate with requirements of federal proceedings.
(10) Once the application, analysis, and a draft agreement are completed, a decision on whether the waiver or exemption shall be granted shall be made by:
(a) The Department:
(A) If it determines that the total stream distance, including tributaries, affected by the artificial obstruction for which the waiver or exemption is being sought is less than or equal to 1 mile to a natural barrier;
(B) If the request is for an exemption under subsection (4)(a) or (4)(b); or
(C) For re-authorization of an existing hydroelectric project subject to ORS 543A.030 to 543A.055 and not subject to federal hydroelectric relicensing; and
(b) The Commission:
(A) In all other instances; or
(B) If the Department refers a decision to the Commission; or
(C) If the owner or operator files a protest of the Department's determination to the Commission.
(11) The decision to grant a waiver or exemption shall include the determination described in subsection (1) or (4) as well as approval of the agreement required in subsection (9).
(12) In addition to the Fish Passage Task Force as prescribed in OAR 635-412-0010(4)(e) and (g), the Department shall notify local watershed council(s), local soil and water conservation district(s), identified stakeholders, and others who have expressed an interest in fish passage issues or the specific waiver or exemption request and provide an opportunity to comment on the request at least three weeks prior to a decision on whether the waiver or exemption should be granted.
(13) The Commission (or Department, as applicable) may require further public comment prior to a decision on whether a waiver or exemption should be granted.
(14) The Department shall maintain a database of the locations of waived and exempted artificial obstructions and mitigation.

(B) Life history stages which require fish passage; and
(C) Dates of the year and/or conditions when passage shall be provided for the life history stages and native migratory fish.
(b) The person submitting the fish passage plan to the Department for approval shall submit all information necessary to efficiently evaluate whether the design will meet fish passage criteria;
(c) If site-specific circumstances indicate that the fish passage criteria are not adequate to provide fish passage, the Department may require in writing that additional fish passage criteria be met;
(d) If native migratory fish- or site-specific circumstances warrant it, the Department may provide an exception to any specific fish passage criterion if the Department determines in writing that fish passage shall still be provided;
(e) All fish passage structures shall be designed to take into consideration their upstream and downstream connection and prevent undesirable impacts to fish passage, including but not limited to scour and headcuts;
(f) If joint state and federal approval is required, the Department shall take into account federal requirements during approval;
(g) Primarily at sites with little existing site information or questionable design solutions, the Department may require monitoring and reporting to determine if a fish passage structure meets applicable criteria and/or is providing fish passage; and
(h) The person owning or operating an artificial obstruction shall maintain the fish passage structure in such repair and operation as to provide fish passage of native migratory fish at all times required by the Department.
(2) Requirements for fish passage at dams and other artificial obstructions which create a discontinuity between upstream and downstream water surface or streambed elevations are:
