(a) Unless provided with a written exemption pursuant to § 12.21, every applicant or licensee must develop and file with the Regional Engineer an emergency action plan and appendices, verified in accordance with § 12.13.

(b) The emergency action plan must be:

(1) Developed in consultation and cooperation with appropriate Federal, state, and local agencies responsible for public health and safety; and

(2) Designed to provide early warning to upstream and downstream inhabitants, property owners, operators of water-related facilities, recreational users, and other persons in the vicinity who might be affected by a project emergency as defined in § 12.3(b)(9).

(a) Grant of exemption. Except as provided in paragraph (b), if an applicant or licensee satisfactorily demonstrates that no reasonably foreseeable project emergency would endanger life, health, or property, the Regional Engineer may exempt the applicant or licensee from filing an emergency action plan.

(b) No exemption. A licensee or applicant may not be exempted from the requirements of § 12.22(c) for a radiological response plan.

(c) Conditions of exemptions. (1) An applicant or licensee who receives an exemption from filing an emergency action plan has the continuing responsibility to review circumstances upstream and downstream from the project to determine if, as a result of changed circumstances, a project emergency might endanger life, health, or property.

(2) Promptly after the applicant or licensee learns that, as a result of any change in circumstances, a project emergency might endanger life, health, or property, the applicant or licensee must inform the Regional Engineer of that changed condition without unduly delaying the preparation and implementation of the emergency action plan.

(3) Comprehensive review of the necessity for an emergency action plan must be conducted at least once each year.

(d) Revocation of exemption. (1) The Regional Engineer may revoke an exemption granted under this section if it is determined that, as a result of any change in circumstances, a project emergency might endanger life, health, or property.

(2) If an exemption is revoked, the applicant or licensee must file an emergency action plan within the time specified by the Regional Engineer.

(a) Contents—(1) The plan itself. An emergency action plan must provide:

(i) Instructions to project operators and attendants and other responsible personnel about the actions they are to take during a project emergency;

(ii) Detailed plans for notifying potentially affected persons, appropriate Federal, state, and local agencies, including public safety and law enforcement bodies, and medical units; and

(iii) Procedures for controlling the flow of water, including actions to reduce in-flows to reservoirs, such as limiting outflows from upstream dams or control structures, and actions to reduce downstream flows, such as increasing or decreasing outflows from downstream dams or control structures, on the waterway on which the project is located or its tributaries.

(2) Appendix to the plan. Each copy of the emergency action plan submitted to the Regional Engineer must be accompanied by an appendix that contains:

(i) Plans for training project operators, attendants, and other responsible personnel to respond properly during a project emergency, including instructions on the procedures to be followed throughout a project emergency and the manner in which the licensee will periodically review the knowledge and understanding that these personnel have of those procedures;

(ii) A summary of the study used for determining the upstream and downstream areas that may be affected by sudden release of water, including a summary of all criteria and assumptions used in the study and, if required by the Regional Engineer, inundation maps; and

(iii) Documentation of consultations with Federal, state, and local agencies, including public safety and law enforcement bodies, and medical units.

(b) Special factors. The applicant or licensee must take into account in its emergency action plan the time of day, particularly hours of darkness, in establishing the proper actions and procedures for use during a project emergency.

(c) Additional requirements for projects near nuclear power plants—(1) Radiological response plan. If the personnel operating any powerhouse or any spillway control facilities, such as gates or valves, of a project would be located within ten miles of a nuclear power plant reactor, the applicant or licensee must file, separately or as a supplement to any required emergency action plan, a radiological response plan that provides for emergency procedures to be taken if an accident or other incident results in the release of radioactive materials from the nuclear power plant reactor.

(2) A radiological response plan must:

(i) To the maximum extent practicable, include sufficient procedural safeguards to ensure that, during or following an accident or other incident involving the nearby nuclear power plant reactor, the project may be safely operated and, if evacuation is necessary, the project may be left unattended without danger to the safety of any project dam or to life, health, or safety upstream or downstream from the project; and

(ii) Explain the provisions, developed after consultation with the direct purchasers of project power, for cessation, curtailment, or continuation of generation of electric power at the project during or following an accident or other incident involving the nearby nuclear power plant reactor.

(3) Time of filing radiological response plan. (i) For a constructed project with an otherwise acceptable emergency action plan on file, any radiological response plan required must be filed:

(A) If an operating license for the nuclear power plant has been issued on or before March 1, 1981, not later than three months from March 1, 1981; or

(B) In all other instances, not later than three months after the date an operating license for the nuclear power plant is issued.

(ii) For any project not described in § 12.22(c)(3)(i), any radiological response plan required must be filed contemporaneously with the emergency action plan or, if the project has been exempted from filing an emergency action plan, at the time the emergency action plan would otherwise have been required to be filed pursuant to § 12.23.

(a) Unconstructed project. (1) Except as set forth in paragraph (a)(2), the emergency action plan for an unconstructed project must be filed no later than 60 days before the initial filling of the project reservoir begins.

(2) Temporary impoundment during construction. (i) For any unconstructed project, if a temporary impoundment would be created during construction, such as through construction of temporary or permanent cofferdams or large sediment control structures, and an accident to or failure of the impounding structures might endanger construction workers or otherwise endanger public health or safety, a temporary construction emergency action plan must be filed no later than 60 days before construction begins.

(ii) No later than 60 days before the initial filling of a project reservoir begins at a project for which a temporary emergency action plan has been filed the applicant or licensee must file modifications to that plan or a new plan, taking into account the differences in circumstances between the construction and post-construction periods.

(b) Unlicensed constructed project. (1) If the Commission has determined on or before March 1, 1981 that a license is required for an unlicensed constructed project, the emergency action plan for that project must be filed no later than:

(i) Six months after March 1, 1981; or

(ii) Any earlier date specified by the Commission or its authorized representative.

(2) Except as set forth in paragraph (b)(1) of this section, the emergency action plan for an unlicensed constructed project must be filed no later than the earliest of:

(i) Six months after the date that a license application is filed;

(ii) Six months after the date that the Commission issues an order determining that licensing is required; or

(iii) A date specified by the Commission or its authorized representative.

(c) Licensed constructed project. If a licensed constructed project does not have an acceptable emergency action plan on file on March 1, 1981 the emergency action plan must be filed no later than:

(1) Six months after March 1, 1981; or

(2) Any earlier date specified by the Commission or its authorized representative.

(d) For good cause shown, the Regional Engineer may grant an extension of time for filing all or any part of an emergency action plan.

(a) The emergency action plan must be continually updated to reflect any changes in the names or titles of project operators and attendants and other personnel with specified responsibilities for actions in an emergency and any changes in names of persons to call, telephone numbers, radio call signals, or other information critical to providing notification to affected persons, Federal, state, and local agencies, and medical units.

(b) An applicant or licensee has continuing responsibility to review the adequacy of the emergency action plan in light of any significant changes in upstream or downstream circumstances which might affect water flows or the location or extent of the areas, persons, or property that might be harmed in a project emergency.

(c) Promptly after an applicant or licensee learns of any change in circumstances described in paragraph (b) of this section, the applicant or licensee must:

(1) Inform the Regional Engineer of that change in circumstances;

(2) Consult and cooperate with appropriate Federal, state, and local agencies responsible for public health and safety to determine any advisable revisions to the emergency action plan; and

(3) File with the Regional Engineer any revisions to the appropriate studies, maps, plans, procedures, or other information in the emergency action plan itself or its appendices that have changed as a result of that consultation.

(d) An applicant or licensee must conduct a comprehensive review of the adequacy of the emergency action plan at least once each year.

(a) A copy of the current emergency action plan itself must be posted in a prominent location readily accessible to the licensee's or applicant's operating personnel who are responsible for controlling water flows and for notifying public health and safety agencies and affected persons.

(b) Each licensee or applicant must annually test the state of training and readiness of key licensee or applicant personnel responsible for responding properly during a project emergency to ensure that they know and understand the procedures to be followed throughout a project emergency.
