Environment Committee


SUMMARY: By law and regulation, the owner of a high or significant hazard dam or similar structure must have an emergency action plan and update it at least every two years, or more frequently if necessary to reflect a significant change (CGS 22a-411a, Conn. Agencies Regs. 22a-411a-2). Under this act, an owner must update the plan by amending only the parts of it that changed, rather than by providing a new, complete plan.

By law, copies of the original plans and updates to them must be filed with the energy and environmental protection commissioner and the chief executive officer of any municipality that could be affected in an emergency.

A high hazard dam is one whose failure would result in probable loss of life, damage to major utilities and roadways, or great economic loss. A significant hazard dam is one whose failure would result in possible loss of life, damage to local utilities and roads, or significant economic loss (Conn. Agencies Regs. 22a-409-2).
