How Michigan takes it
Michigan files through Tier II Manager, and we have not found anything from the state saying that system imports an EPA Tier2 Submit file — so plan on typing from our worksheet, the state’s online system. Reports run January 1 to March 1 for the year before.
Michigan’s own pages name no filing fee. That is not the same as the state saying there is none, so if it matters to your budget, ring them and ask.
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. Michigan does not pass it on for you — we checked. Filing closes the state’s copy only; your local committee and fire department each need their own from you.
Before you send it — what else Michigan asks for
Filing with the state closes one of three: Michigan tells you to send the annual report to the SARA Title III Program, your local emergency planning committee and your local fire department. The state lists 49 counties whose committees and fire departments will take it online, so check whether yours is one before you print anything. Michigan also has two duties that sit outside Tier II. Your fire chief can require a list of chemicals and where they are kept, at whatever quantities they name — the 1941 Fire Prevention Code, and it is not tied to the Tier II thresholds. And if your site falls under the Part 5 rules, you must tell your local emergency planning committee that you have completed a Pollution Incident Prevention Plan, within 30 days of finishing it. 1994 PA 451. We do not work out whether Part 5 applies to you — ask the state.
Does Michigan set its own limits?
The Michigan rule people cite for this is a different programme, not a lower Tier II threshold.
Michigan keeps the federal thresholds — 10,000 lb, and 500 lb or the threshold planning quantity for an extremely hazardous substance, whichever is lower. The Michigan-only part is not a number: your fire chief can require a list of what you hold and where, at whatever quantities they specify, under the state’s Fire Prevention Code. That duty is independent of Tier II and of these thresholds, so a site that is under every federal limit can still owe the fire department a list. Ask your fire chief what they want.
The words we read
Michigan EGLE, “Michigan Facilities’ Guide to SARA Title III” Rev. 12/2023 (michigan.gov/egle), read in full 2026-09-11. On thresholds it uses the federal numbers and nothing else: its own decision flowchart asks “Is the chemical on site in an amount equal to or greater than 10,000 pounds?” and “Is the EHS ever on site in an amount equal to or greater than 500 pounds?”, and the guide restates 40 CFR Part 370 throughout without naming a Michigan figure. What it adds is a separate programme: “The Michigan Fire Prevention Code, Public Act 207, requires that the owners and operators of facilities provide the fire department with the quantities and locations of chemicals specified by the fire chief. The data are used by the fire chief to develop a plan for the protection of the fire fighters. The chemicals that must be reported under Act 207 include all hazardous chemicals at the facility in amounts that might be of concern.” A second one sits under Part 31 of 1994 PA 451: facilities with a Pollution Incident Prevention Plan “must notify their LEPC within 30 days after its completion.” The guide names no Tier II filing fee anywhere in its 142 pages — that is a statement about the document, not proof that none exists.
Where we read this
- Michigan EGLE (SERC), SARA Title III Tier II reporting (read 2026-09-05): “Tier II Manager is Michigan’s official online system”; “Act, 1994 PA 451, as amended, requires that facilities subject to the Part 5 rules provide notification to the LEPC that they have completed a Pollution Incident Prevention Plan (PIPP) or an integrated contingency plan containing the PIPP requirements.” On who sends the local copies, read directly on 2026-09-11 in the state’s own “Michigan Facilities’ Guide to SARA Title III” (Rev. 12/2023, 142 pages): “Facilities covered by Section 311 must, under Section 312, annually submit an emergency and hazardous chemical inventory form to the LEPC, the SERC, and the local fire department,” and its reporting flowchart says to “submit annual report by March 1 to: the Michigan SARA Title III Program, your LEPC, and your local fire department.” The EGLE programme page adds that “Fire Departments and Local Emergency Planning Committees in the following counties can receive your Tier Two report online” and names 49 of them. The same guide carries the Fire Prevention Code duty: “The Michigan Fire Prevention Code, Public Act 207, requires that the owners and operators of facilities provide the fire department with the quantities and locations of chemicals specified by the fire chief.”Checked 2026-09-11
