15 CAR § 23-504 – Hazard classification criteria

(a) All dams will be classified or reclassified as required to ensure appropriate safety considerations.
(b) Hazard classification shall be based on the more stringent of either potential loss of human life or economic loss in accordance with Table 2 of this section.
(c) If doubt exists concerning classification, the more hazardous category must be selected.

(d) Note. The hazard classification does not indicate the physical condition of a dam.
