How Maryland takes it
Maryland takes Tier II only through MDE’s own system, MOTTRS, where you key the data in. Our answer is the worksheet you type from.
Maryland charges a yearly fee that is due by 1 June, not 1 March like the report. Everything one owner or operator runs in Maryland pays no more than $1,000 a year in total.
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. Maryland takes the filing, but your fire department still needs its own copy from you. Maryland says the local emergency planning committee does not — so this is two recipients, not the usual three.
Before you send it — what else Maryland asks for
Filing in MOTTRS reaches the state and your local emergency planning committee — MDE shares the inventory with every Maryland LEPC. The fire department is separate: MDE says to ask your LEPC how to get the report to it, and the system will print a hard copy for that. It will also carry a site plan as an attachment, which the file we build does not contain. There is no paper route to the state — MDE says every report must go through MOTTRS. And you cannot start on the day: the system tells you to register before using it, so ask for an account well before 1 March. The login sits at a “tier2manager” address, which elsewhere often means a system that can import an EPA file — but nothing MDE publishes says this one does, so plan on typing.
Does Maryland set its own limits?
Maryland appears on published lists of stricter states, but we could not find a Maryland rule that sets different thresholds. We use the federal ones and say so rather than guess.
We treat Maryland as federal until we can read a Maryland rule that says otherwise.
The words we read
A secondary source lists Maryland as setting local thresholds. We could not find any Maryland rule that does, and the state’s own site refused our requests, so we treat Maryland as federal until we can read a Maryland rule that says otherwise.
Where we read this
- MDE, “Maryland Online Tier II Reporting System (MOTTRS)” slides, read 2026-09-07 through the Internet Archive capture dated 2025-04-19 (hosted by Baltimore City OEM): “Reports are due each year by March 1st.” · “All reports must be submitted online using the MOTTRS.” The system’s own front page (securesite.mde.state.md.us/tier2manager), read 2026-09-07: “You must register before using this Online Reporting System.” Nothing we read says MOTTRS imports an EPA Tier2 Submit file, so we do not claim ours works here. Trade summaries mention a fee; we found none stated by MDE and do not repeat it.MDE’s own Tier II page (mde.maryland.gov), read 2026-09-11 through the Internet Archive snapshot dated 2026-02-16 (the live site refuses our requests, so this is the page as of that date): “Reports are due March 1st of each year,” and “The reports are submitted to the State Emergency Response Commission (SERC), the Local Emergency Planning Committee (LEPC) with jurisdiction over the facility, and the local fire department that would respond to any emergency at the facility.” On what the system does for you: “Supplemental files like Site Plans can be attached to the inventory report,” and the system “can print hard copy Tier Two report for submission to LEPC, local fire department, and for facility records.”MDE, “Tier Two Reporting” page (mde.maryland.gov), read 2026-10-12 through the Internet Archive snapshot dated 2026-02-16 because the live page refuses our requests with HTTP 403: “MDE is shares electronic chemical inventory with all Maryland LEPCs.” [sic] and “Note: Please contact your LEPC for instructions regarding Tier Two submissions to the local fire department.”Checked 2026-09-11
