Tier II - Emergency and Hazardous Chemical Inventory FAQs
Who must comply with this reporting requirement?Under EPCRA Section 312, facilities and businesses are required to report inventories of substances or products that meet or exceed reporting thresholds. They must submit a Tier II Emergency and Hazardous Chemical Inventory report by March 1st of each year for the inventory of hazardous substances or chemicals stored on site during the previous calendar year. Refer to the Tier II Report Instructions.
What type of information is required to be reported in a Tier II submission?
- The calendar year for the reporting period.

What are some typical reporting examples? (Source: EPA, Region 1)
Most pesticides contain EHSs and have Tier II reporting thresholds from 1-10,000 lbs.
If you store more than 1,562 gallons of heating oil, you have exceeded the reporting threshold.
A walk-in cooler or refrigeration system with more than 500 lbs of ammonia requires reporting.
A facility with 500 lbs of nitric or sulfuric acid must report.
If you use 100 lbs of hydrofluoric acid (hydrogen fluoride) you must report.
If you alter (cut, weld, grind, braze) more than 10,000 lbs of metal stock, your facility must report.
If you sell or service industrial batteries that contain sulfuric acid, you may have to report.
Contractors may have a reporting responsibility for construction materials on site.
Owners, operators or renters of warehouses may have to report.
Bleaching/cleaning solutions containing sodium hypochlorite are reportable.
If you have a total of 10,000 lbs (2,500 gallons) of propane for heating or distribution, you must report.
What information may be withheld from disclosure in a Tier II submission?
Where can I find information regarding chemicals and hazardous substances?
What is the reporting threshold for gasoline and diesel fuel at retail gas stations that store their product entirely underground and are in full compliance with underground storage tank requirements?
Refer to EPA Amendments to Hazardous Chemical Reporting Thresholds for Gasoline and Diesel Fuel at Retail Gas Stations, Final Rule, 64 CFR 7031 (PDF) that raised the reporting threshold for gasoline to 75,000 gallons and diesel fuel to 100,000 gallons at retail gas stations that store their product entirely underground and are in full compliance with the Underground Storage Tank requirements.
Is a state facility exempt from Tier II reporting requirements?State facilities are not exempt from the CGS, Sections 22a-609 and 22a-610 reporting requirements nor from Conn-OSHA standards and implementing regulations. The federal law, EPCRA Sections 311 and 312 apply to owners and operators of facilities who must prepare or make available MSDS under the federal OSHA and its implementing regulations. The federal OSHA applies to "employers" and states are excluded from the federal definition of "employers." The federal and state reporting requirements establish ground rules for submitting information about the presence of hazardous chemicals in the communities. The federal law does not preempt existing state or local laws. CONN-OSHA administers the states' occupational safety program in lieu of the federal government's OSHA program.
What are the requirements for Lead Acid Battery Reporting Under EPCRA?OSHA determined that lead acid batteries are hazardous chemicals under the OSHA definition since there are chemical and physical hazards associated with them. Lead acid batteries have the potential to emit hydrogen gas which, upon ignition, may result in a fire or explosion. Furthermore, OSHA’s Directive on Inspection Procedures for the Hazardous Communication Standard state that lead acid batteries do not fall under the article exemption because they have the potential to leak, spill, or break during normal conditions of use, including foreseeable emergencies. For more guidance regarding mixture, or non-EHS chemicals, review the EPA issued guidance Lead Acid Battery Reporting Guidance under EPCRA Sections 311 and 312.
What are the reporting requirements for hazardous chemical exemption for solids?
Refer to the EPA interpretation (PDF).
When is the Tier II Report due?
Tier II reports are due on or before March 1.
Who do I submit a Tier II Report to?
Tier II reports must be submitted to the SERC via the software identified below. You must submit Tier II information to the LEPC and the fire department who has jurisdiction over your facility. Please be aware that towns have various practices for collecting Tier II information. The facility owner or operator should contact the LEPC chairperson (if there is one appointed) and Fire Department for the town's specific submission requirements. If a town LEPC belongs to a regional LEPC (PDF) (note regions may have various roles depending upon the region needs) the submitter should first contact the town LEPC to verify who (region or local LEPC or fire department) is accepting the Tier II form.
Who requires the submission of locations of hazardous chemicals or site plan with the Tier II form?
DEEP, in its role as SERC administrator, requires a description of the precise locations of the hazardous chemicals at your facility, including a site plan. You may upload the site plan into the reporting system.
Is there specific software designed for entering facility information on the Tier II form?
Yes, the Connecticut State Emergency Response Commission and the Department of Energy and Environmental Protection will be using the free Hazconnect® Tier II Manager system to manage EPCRA Tier II chemical inventory reports due March 1, 2023 and going forward.
To use the Hazconnect® Tier II Manager platform please register for a system user account. This enables CT DEEP/SERC to link your facility's account data to your user account so that you can work from your existing information when submitting your next report. Here's how:
1. Sign up as a User at this link: https://connecticut.hazconnect.com/Account/Login.aspx
2. Click on the REGISTER button in the middle of the page.
3. Choose Reporting Facility/Business User then click Next.
4. Enter your information. Please be sure you enter information in the “Facility Details” text box at the bottom of the screen to inform CT DEEP of facility reports you have submitted in the past. Using this information CT DEEP will link the previous year’s report for that facility to your new user account so you can start with data pre-populated.
5. Once your User account is approved, you will receive a notification and then you can begin submitting the next year’s report. If you don’t see previously submitted reports in your account, please contact us at DEEP.CTEPCRA@ct.gov.
Connecticut will also continue to accept submittal of reports via EPA's Tier2 Submit™ Software with electronic file submissions sent to DEEP.CTEPCRA@ct.gov.
Tier2 Submit is free, personal computer software developed by EPA and NOAA for use by facilities in submitting Tier II Chemical Inventory Reports. The software assists you through the preparation of the Tier II report.
I used Tier2 Submit software last year to report my facility's Tier II information. Do I need to download Tier2 Submit software each year?Yes, facilities must use the current Tier2 Submit software to report Tier II information for the prior reporting year. The software is updated every year to include new reporting requirements and software system improvements. Users can import their last year data into the current Tier2 Submit software; refer to the EPA Tier II Instructions, or the Tier2 Submit Facility Submission Guide.
What steps must be taken to ensure my email containing a Tier II form is recognized as a formal document?
If you use the Tier II Manager platform to submit your report, you do not need to email the report. If you use the Tier2 Submit platform, you will need to email your submittal to CT DEEP. To ensure your email is recognized as a formal document and not spam, the email subject line should reflect the following wording "(Name of your facility), Tier II." All emails must be directed to DEEP.CTEPCRA@ct.gov.
