Any spill or overfill that exceeds 25 gallons or that causes a sheen on nearby surface water must be reported to the DEEP. Spills or overfills under 25 gallons that are contained and immediately cleaned up do not need to be reported. If they cannot be cleaned up within 24 hours, they 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.
