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, therefore the new version must be installed 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).
