Connecticut moves to renew water-use permits that expire January 2027; comments closed September 18
DEEP's four general permits for water diversions, including testing, cooling and remediation uses, are up for reissuance, and anyone relying on current coverage should compare the new terms before January 18, 2027.
On July 20, 2026, the Connecticut Department of Energy and Environmental Protection ("DEEP") published a notice of intent to renew its four general permits for the diversion of water for consumptive use, with written comments due within 60 days of publication; DEEP's proposed-permits listing and program page give the closing date as September 18, 2026. The comment period has closed. As of DEEP's public-notice listing reviewed on October 5, 2026, no final decision on renewal is posted, and the existing permits expire on January 17, 2027. For owners and developers whose projects rely on a registered or authorized water diversion, the open question is what the reissued terms will require when they take effect.
