Updating Procedures

In accordance with Env-Wr 507.01, Emergency Action Plans (EAPs) for high hazard dams are to be tested, reviewed and updated accordingly, every two years. EAPs for significant hazard dams are to be tested, reviewed and updated every four years. If changes to the EAP become necessary before the review is due, they should be made immediately in accordance with Env-Wr 507.02. The following procedures will assist you in this process. It is recommended that you contact the Dam Bureau at (603) 271-3406 or , prior to distributing updates to your EAP, to discuss the necessary changes.

Reviewing and Updating
Before testing your EAP, you should review it to be certain that all emergency contact numbers are correct. This can be done by contacting each agency included in the notification checklist. Local emergency responders and dispatchers should be called individually.

The notification tree for State agencies and their appropriate telephone numbers can be viewed on the sample notification flowchartMicrosoft Excel Symbol. It is recommended that you view this sample to ensure that all contact numbers are correctly listed, and that your flowchart includes 911 as the primary contact. Please note that the NH Department of Environmental Services’ contact number was changed in January, 2003.

If there are any changes necessary to your EAP, either as related to the notification procedures or other portions of the EAP (see "Document Template", below), all amended pages should be mailed out to holders of the EAP.
