There are five reporting requirements that may apply to a Connecticut facility or business:
The Consolidated List of Lists for reporting thresholds will provide you with the necessary information to determine if there is a reportable quantity of any extremely hazardous substances (EHS) on site or a product that contains an EHS. If this is the case, the facility owner or operator should submit a Section 302-Emergency Planning Notification within 60 days of the date it arrived on site.
If there are 10,000 pounds or more of a hazardous substance or a reportable quantity of an extremely hazardous substance on site at any one time, the facility owner or operator should submit a Hazardous Chemical Reporting requirement within 90 days of the date it arrived on site.
If there are 10,000 pounds or more of a hazardous substance or a reportable quantity of an extremely hazardous substance on site at any one time, a facility owner or operator is required to submit a Tier Two, Emergency and Hazardous Chemical Inventory each year. The inventory that is due by March 1st is for the previous calendar year (January 1 - December 31).
