A spill or overfill of any size, especially if it causes a sheen on nearby surface water, must be reported to the DEEP. Report spills or other environmental emergencies to the DEEP:
- 24 hours per day at 860-424-3338 or toll free at 1-866-DEP-SPIL (1-866-337-7745); or
- Should these numbers become unavailable for any reason, call 860-424-3333.
If a release is confirmed, a written report must be submitted to the DEEP commissioner within 3 working days of discovery. It must include the estimated amount of product lost, location of the release, and identification of leaking components of the UST system. Actions taken and the results of those actions must be reported to the DEEP within 20 days of release confirmation.
