Tier II hazardous chemical inventory reporting

Back to SARA Title III

Reports for Tier II must occur through the Colorado Environmental Online System (CEOS). This will take place in three steps:
1. Create a CEOS account. All reporting companies are required to create have an account in CEOS. If you don't have one, click the link below to get started. If you already have a CEOS account, you can proceed to step 2. 
2.  Create a Report. We require the use of the EPA’s free Tier2Submit software to create a report called a "T2S report". Each year, the software is updated and the new version must be downloaded and used by the reporter.
All Tier II reporters must download the updated software every year. 
How to create a T2S report
This document from the EPA demonstrates how to build a report.
3. Submittal and payment. Once the report has been created in Tier2Submit and registration in CEOS has been completed, companies MUST submit the final Tier II report through CEOS. Online payment fees will be generated through CEOS and can be completed when submission is done. E-mail submissions will NOT be accepted. The deadline for report submission is 5:00 p.m. (MST) March 1, 2019

Additional Information
Facilities are not required to provide the same report to the local emergency planning committee (LEPC) or the local fire department unless those agencies maintain local reporting requirements. Please check with your LEPC and fire department for local requirements.
