35. An emergency action plan must be drawn up before the commissioning of any dam. The plan shall set out the procedures to be followed for the protection of persons and property upstream or downstream of the dam in the event of an actual or imminent dam failure or to mitigate the effects of the disaster.
The plan must include
(1) the name of the local municipality, regional county municipality or any other regional body whose territory would be affected by a dam failure;
(2) a list of the conditions that could lead to a dam failure;
(3) a general description of the area that would be affected by a dam failure, including the principal infrastructures that would be destroyed or severely damaged;
(4) a description of the internal and external human, material and organizational resources that would be available in the event of a disaster; and
(5) a description of the monitoring and warning procedures in the event of an actual or imminent dam failure that have been established by the owner, including
(a) a description of the prevention, potential dam failure detection and mitigation measures established by the owner;
(b) warning and dam personnel mobilization procedures for the various conditions that may lead to a dam failure;
(c) the procedure for warning civil protection authorities and, where applicable, residents; and
(d) the operation and decision centre.
The inundation maps referred to in the first paragraph of section 18 must be appended to the emergency action plan. The maps must indicate the dam break flood wave travel time in the event of a dam failure in normal conditions and during floods and take into account, for the latter eventuality, the water elevation equal to the safety check flood for the dam. Only rough maps that comply with the second paragraph of section 18 are required for dams in the Moderate Consequence category.
