Dam Safety Regulatory Program


1. The CT DEEP Dam Safety Program is offering the option of submitting all Dam Safety Permit Applications electronically. Please follow these steps to submit Dam Safety Permit Applications to DEEP.

2. The Connecticut Department of Energy & Environmental Protection (CT DEEP) Dam Safety Program is trying to improve how we communicate with the public. The first step is to develop an email distribution list of people interested in receiving CT DEEP Dam Safety program updates. Please feel free to email us at with an email address that would like to be added to this group. Our goal is to create a CT DEEP Dam Safety Program email "listserv" where you may subscribe and unsubscribe for our emails.
The mission of the Connecticut 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.
