How Maine takes it
Maine takes only the Tier2 Submit file, sent by email or on a CD, and charges registration and inventory fees. EPA’s list carries no Maine web page, so the way in is the agency itself: maine.serc@maine.gov, (207) 624-4400.
The file we build is the one this state works from.
The filing is due 1 March each year and covers the calendar year before it. Maine 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 Maine asks for
Maine puts out a new Tier2 Submit version around November each year, and filing on last year’s version is a common rejection. We build on the current one. Three things Maine adds that the federal form does not. There are fees: up to $100 to register the facility, plus a reporting fee charged by weight per chemical, capped at $5,000 for the facility (retail petroleum marketers at or below 75,000 pounds of storage per product, and commercial agricultural operations, are exempt). The inventory asks for your standard and alternate transportation routes through the State, so collect those before you sit down. And if you hold an extremely hazardous substance above its threshold planning quantity, Maine expects a facility emergency response plan, given to your LEPC and fire department, reviewed and exercised every year, with a yearly letter to the state commission saying so. Maine’s own form adds two questions: a list of your emergency response equipment with a 24-hour contact for it, and whether your site is inside a community water system area.
Does Maine set its own limits?
We have read Maine's own code and it uses the federal thresholds. That is a checked answer, not an assumption.
Maine keeps the federal thresholds. But it wraps them in a state programme with its own name, its own fees and one field the federal form does not ask for. Collect your standard and alternate transportation routes through Maine before you file. If you hold an extremely hazardous substance above its planning quantity, Maine also expects a facility emergency response plan. You review and exercise that plan every year.
The words we read
Maine runs the programme under its own statute — 37-B M.R.S. ch. 13, subch. 3-A (§§ 791–806) — read 2026-09-07. § 797, “Maine chemical inventory report”: it is owed by “a person required to submit a facility emergency response plan, material safety data sheet or list of hazardous chemicals and extremely hazardous substances,” and “the inventory report and fee must be submitted by March 1st annually for the previous calendar year,” going to “the commission, the local emergency planning committee and the local fire department with jurisdiction over the facility.” Besides the usual chemical name, maximum pounds present at any time in the year, average daily amount, manner of storage and location, it asks for a shipping description including “standard and alternate transportation routes taken through the State.” § 795 covers facility emergency response plans and § 801 the fees: a registration fee “not to exceed $100 per facility” plus a reporting fee charged “a weight basis per chemical,” with “maximum fees of $5,000 per facility for reporting hazardous materials,” and exemptions for retail petroleum marketers at or below 75,000 pounds of storage capacity per product and for commercial agricultural operations. On the numbers themselves, MEMA’s own facility page keeps the federal tests: hazardous chemicals “above 10,000 pounds (that’s about 1500 gallons of liquid products)” and extremely hazardous substances at the TPQ, and “filing must be done electronically, using US EPA’s Tier II Submit software.”

- Maine Emergency Management Agency (SERC), facility resources (maine.gov/mema/hazards/serc, read 2026-09-06): “The State of Maine accepts chemical inventory reports only via Tier II Submit. Filing must be done electronically, using US EPA’s Tier II Submit software, available free from the EPA” — submitted “through e-mail or on a CD”. Fees: “there are registration and inventory fees associated with the reports”. EPA’s state list adds: “A new version of Tier2 Submit is created around November of each year.”MEMA, “Complete Tier 2 Reporting Package for 2025” (maine.gov, dated 30 October 2025), read 2026-10-12: Enclosure 1 is the “SERC Facility Emergency Response Plan and Exercise Annual Letter of Certification” for facilities with an extremely hazardous substance at or above its planning quantity; Enclosure 10, “State Field Requirements for Maine – New Questions”, adds a list of emergency response equipment with an emergency equipment 24-hour contact, and “Is your facility located within a Community Water System area?”.Checked 2026-09-07
