Emergency Action Plans Program

Dams in New Hampshire are classified in one of four hazard categories – Non Menace, Low Hazard, Significant Hazard, and High Hazard. The NHDES Fact Sheet entitled "Classification of Dams in New Hampshire" provides detail and definition for the hazard categories.

Under the New Hampshire Code of Administrative Rules ENV-WR 303.06, owners of all High Hazard and Significant dams whose failure could threaten public safety or result in major economic impact or property loss, are required to compile and maintain an Emergency Action Plan (EAP) which addresses the area of concern and identifies procedures to be initiated in the case of a dam failure. NHDES has developed a template and can provide technical assistance to dam owners in preparing their EAP’s according to the state’s rules.
