The mission of the DEEP Dam Safety Regulatory Program is to ensure the safety of dams to protect life, property, and the environment by ensuring that all dams are designed, constructed, operated, and maintained safely and effectively. The Dam Safety Statutes were last substantially revised by Public Act 2013-197, which authorized changes regarding Emergency Action Plans (EAPs) and inspection requirements:
  • Dam owners in the State of Connecticut are now responsible for hiring a consultant to conduct regular dam inspections. 
  • The owners of high hazard (Class C) and significant hazard (Class B) dams must file an EAP every two years.
