Tier II hazardous chemical inventory reporting
Information for reporting facilities
Colorado requires that Tier II reports be filed using EPA’s free Tier2Submit software. Tier2Submit will generate an electronic file that must be emailed to the state - you cannot submit the file directly from Tier2Submit. The Tier2Submit software is revised every single year. You must install a new version each year.

Colorado has instituted a single-point submission process for Tier II reporting. Facility owners/operators are required to submit their Tier II report(s) to the Colorado Department of Public Health and Environment. 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 to determine if they require direct Tier II reporting to their agency.
