Plan Requirements for New Dams or to Increase Dam Height: Operations and Maintenance Plan

(1)

The Engineer of Record shall include an operations and maintenance plan with the submittals for building a new Dam or increasing Dam Height for:

(a)

Any Dam rated Significant or High Hazard; and

(b)

Any Low Hazard Dam with:

(A)

A Gate or flashboard as part of the Spillway; or

(B)

A Valve on a Conduit that is not on the upstream side of the Dam.

(2)

The Department may review implementation of the operations and maintenance plan during Dam safety inspections.

(3)

Operations and maintenance plans shall include, but are not limited to:

(a)

Directions for filling and emptying the reservoir when needed;

(b)

Frequency of inspection of the interior of Conduits, including qualifications and guidance for Persons conducting and reporting on this inspection;

(c)

Procedures for operation of all Gates and Valves;

(d)

Specified minimum frequency for cycling and lubrication of all Gates and Valves;

(e)

Standards for removal of trees and brush, and mowing other vegetation; including the frequency for the Dam owner to monitor vegetation and to take action to control brush if it obscures any face of the Dam, the Conduit, or the Spillway;

(f)

Frequency of routine Dam observations, including identification of changes in seepage and maximum permissible Dam deformations;

(g)

A Water release plan in the event of a flood forecast when reservoir is above the maximum safe operating level established by the Engineer of Record;

(h)

The measurement frequency for all monitoring instrumentation installed at the Dam; and

(i)

Review and evaluation of conditions of the Dam as necessary to keep the Dam in good repair and properly maintained, including actions identified in OAR 690-020-0250 (Maintenance of Dams).
