Connecticut Tier II Reporting: Deadline, Filing Method & Fees

Facilities in Connecticut storing hazardous chemicals above EPA reporting thresholds file an annual Tier II report through CT DEEP Hazconnect (Tier II Manager). Register and submit via CT DEEP's Hazconnect Tier II Manager portal. .t2s is generated as an EXPORT from within Hazconnect (for records/CAMEO/LEPC-fire sharing), not a separate email-to-DEEP submission path..
