The 2025 Tier II Filing season is upon us. They are due January 1, 2026 and before March 1, 2026.
The Tier II payments for 2024 were due between September 1 and November 1, 2025. A letter was sent in August 2025. This letter for “2024 filing fee letter” is listed under documents. If payment was not made, you will see it reflected on your 2025 Fee sheet.
MISSOURI TIER II reports are due between January 1 and March 1 annually, the reporting information is for the previous year. Please review filing instructions carefully. Only the MISSOURI TIER II form is acceptable for EPCRA reporting in Missouri, we do not accept "Tier II Submit" reports.
This website is different in that all facilities are filed under the company name. To submit your Tier II, go to the Fee Sheet and follow to third screen, check the box "tier II is ready to submit." Your Tier II will not be dated unless you have submitted. Look at facility list, then click "view" to see if it is dated.
We can now accept electronic signatures; this is the name you input at the bottom of the facility page.
The electronic MISSOURI TIER II filing website is: https://apps1.mo.gov/MERC This site works best with EDGE or Chrome.

The MERC Tier II system isn’t setup to use the back arrows within the browser. To save information changed in the system you must click save. DO NOT USE THE BACK BUTTON.
Only company users can click the Fee Sheet to submit the Tier II. Your Tier II is not complete until the box is checked that says ready for submission and any past due the fees have been paid.
