Tier2 Submit Software
Tier2 Submit™ is a program to help facilities prepare electronic versions of the Tier II hazardous chemical inventory form that are required annually under the Emergency Planning and Community Right-to-Know Act (EPCRA).
Tier2 Submit includes all of the fields from the federal Tier II form, and it also includes additional fields that are required or requested by some states and tribes.
The program is updated yearly, and only the most recent version can be used to create the current year’s annual Tier II submission file. The newest version is Tier2 Submit 2024, which is for reporting year 2024.
Completed Tier II forms for this reporting year are due by March 1, 2025. Contact your state or tribe to see if they accept Tier2 Submit files and to learn the specific reporting requirements and submission details for your facility.
Tier II hazardous chemical inventory data can also be exported from Tier2 Submit into CAMEO Data Manager, which can be used to complete additional emergency planning and response activities. These tools are both part of the CAMEO® Software Suite.

Significant Changes in Tier2 Submit 2024
- Enhanced the Contact record interface so that the initial data fields display dynamically based on the chosen Contact Type(s).
- Updated state-specific fields for reporting year 2024.
- Added flexibility to the Maximum Number of Occupants field when the facility is marked as Unmanned to allow states, tribes, and territories to collect additional data if preferred in their areas.
- Updated the county boundary checks to use the latest files from the U.S. Census Bureau.
- Modified behavior to allow Tier2 Submit 2024 to be run side-by-side with an older Tier2 Submit 2023 (or 2022) version. However, the 2023 and 2022 versions should still NOT be run at the same time.
- Made many smaller user interface refinements and enhancements.
- Fixed several small bugs.
- Revised the help topics.
Import Information
- Tier2 Submit 2024 can only be used to make submission files for the current 2024 reporting year. However, you can import .zip and .t2s files from reporting years 2023 and 2022 to use as a baseline dataset that you can update with this year's data (rather than typing in all your data manually).
- If you have problems importing files into Tier2 Submit or you need to make a submission file for a previous reporting year, contact the Risk Management Program (RMP) Reporting Center (see details below).
