OAR 690-020-0400
Emergency Action Plans (EAP)

(1)

An owner of a High Hazard Dam shall develop an Emergency Action Plan (EAP) consistent with this section. The EAP is to assist the Dam owner and local emergency management personnel to ensure human safety in the event of a potential or actual Dam Failure.

(2)

For new Dams or to increase the Dam Height of High Hazard Dams, the EAP is required to be submitted as part of the plans and specifications in OAR 690-020-0035 (Minimum Engineering Requirements for Final Design of New Dams or to Increase Dam Height) and OAR 690-020-0080 (New Dams, or to Increase Dam Height, Written Approval by State Engineer)(1), prior to commencing new Dam construction.

(3)

Owners of Dams which have been reclassified to a High Hazard Rating will be required to develop and submit an EAP within one year of being notified of the reclassification by the Department.

(4)

An EAP shall contain, at a minimum, the following key elements:

(a)

Means for emergency condition detection;

(b)

Means for emergency level determination;

(c)

Identification of, and information necessary for, notification and communication to be made at each level of emergency condition, including, but not limited to, contact information required in OAR 690-020-0180 (Requirement of Owners to Provide Contact and Transfer of Title Information)(1);

(d)

Description of actions to prevent a Dam Failure incident or to help reduce the effects of a Dam Failure and facilitate response to an emergency;

(e)

A map of Dam Failure inundation zones developed using a Dam breach inundation analysis for varying conditions as specified by the Department, including, but not limited to, dry weather conditions and high flood conditions. The Department may require one inundation map if the dry weather and high flood flows are not substantially different. The inundation mapping must include cross sections at locations of concern, and a description of expected depth and velocity of maximum breach flows at each cross section; and

(f)

Procedures for termination of the emergency.

(5)

The Dam owner shall file copies of the EAP with the Department, the Office of Emergency Management, and the local emergency services agency for the county where the Dam is located.

(6)

The Department will, in consultation with the local Office of Emergency Management:

(a)

Periodically review the EAP and may require updates to the plan that recognize the actual capabilities of the local emergency managers; and

(b)

Determine the appropriate frequency for conducting emergency response exercises.
