How Missouri takes it
Missouri does not take the federal Tier2 Submit file. You file through the Missouri Tier II site, where every facility sits under a company name. Submitting is a two-step thing here: you fill the report in, then open the fee sheet and tick the box that says it is ready for submission — and it does not count as submitted while any fee from an earlier year is still owed.
This state does not take the file. Our answer works as the worksheet you type from, with the rule behind every number.
The filing is due 1 March each year and covers the calendar year before it. Missouri will send the local copies for you, but only if you pay for that when you file. If you do not, the local emergency planning committee and the fire department are yours to send.
Before you send it — what else Missouri asks for
Missouri charges $100 a year, plus $20 for each hazardous substance or mixture beyond the first three, so the bill grows with the length of your list. Distribution is a separate $10 per facility and it is optional — if you do not pay it, you are the one who has to send the report to your fire department and local emergency planning committee. Family farms and local governments pay nothing, but still have to send in a signed fee sheet. Two Missouri-only duties sit outside the filing entirely: explosives or blasting agents over 100 pounds go to the fire department within 24 hours, and buildings, rooms and containers holding hazardous chemicals have to carry NFPA 704 markings.
Does Missouri set its own limits?
Missouri keeps the federal numbers but adds a separate filing of its own. Meeting the federal rule is not the whole job here.
Missouri keeps the federal Tier II thresholds but adds two duties the federal rule does not have. The first is fast: more than 100 pounds of explosives or blasting agents on site has to be reported to the fire department within 24 hours of it arriving — not 60 days, not three months, one day. If it stays longer than 15 days it also goes to the fire department, the LEPC and the state commission on the Missouri Tier Two form. Material passing through in a truck is exempt, as long as the carrier is following the federal transport rules. The second duty is physical rather than paper: Missouri requires buildings, rooms and containers holding hazardous chemicals to be marked to the NFPA 704 standard. Neither of these is closed out by filing Tier II.
The words we read
Missouri Emergency Response Commission, “Tier Two Instructions” (sema.dps.mo.gov, read 2026-09-09): “Under Missouri law, explosives and blasting agents in excess of one hundred (100) pounds must be reported to the fire department within 24 hours of being present at a facility. If storage is longer than 15 days, these substances must be reported to the fire department, the LEPC, and the Missouri Emergency Response Commission using the Missouri Tier Two form. This requirement does not apply to materials in transit provided that the transporter is in compliance with U.S. Department of Transportation regulations.” The same document sets out who pays: “Family farms and local governments are exempt from paying fees, however, a signed fee sheet must be sent to the MERC,” and a family farm is “an unincorporated farming unit owned or leased by one or more persons residing on the farm or actively engaged in farming.” MERC’s companion “How to Comply with the Emergency Planning and Community Right-to-Know Act” adds two Missouri-only duties: the state “contains special reporting requirements for 100 lbs. of explosives and blasting agents on site,” and “state law requires markings on buildings, rooms and containers where hazardous chemicals are present. These markings are to conform to the NFPA 704 standard.” The underlying rule is 11 CSR 40-4.040.

Where we read this
- Missouri Emergency Response Commission, Tier II filing site (read directly 2026-09-01): “we do not accept ‘Tier II Submit’ reports”; “The Optional Distribution is a $10.00 charge per each facility.” MERC, “Tier Two Instructions” (sema.dps.mo.gov, read 2026-09-09): “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 fees have been paid,” and “Family farms and local governments are exempt from paying fees, however, a signed fee sheet must be sent to the MERC.” On the amounts, RSMo 292.606 sets an annual fee of one hundred dollars with an additional twenty dollars for each hazardous substance or mixture reported beyond three. The 24-hour explosives duty and the NFPA 704 marking duty are quoted in full on the Missouri rule entry.Checked 2026-09-09
