How Massachusetts takes it
Massachusetts files through MA Hazconnect, 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.
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. Massachusetts 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 Massachusetts asks for
Massachusetts says plainly that filing in their system does not cover your local emergency planning committee or your fire department — you send to those separately, in whatever format each one asks for. The state charges no fee, though some towns do.
Does Massachusetts set its own limits?
Massachusetts's own agency says it uses the federal thresholds, and we read that page rather than assuming it. We have not gone behind it to the state code, so we say that too.
Massachusetts uses the federal numbers — 10,000 lb for a hazardous chemical, and 500 lb or the threshold planning quantity for an extremely hazardous substance, whichever is lower. What it does add is at the other end. Filing in MA Hazconnect closes the state’s copy only, and the Commonwealth says so outright. Your local committee and fire department still need theirs, in whatever format each asks for.
The words we read
Two documents the Commonwealth publishes itself, both read 2026-09-11. Its annual Tier II memo dated 6 January 2026: “Facilities covered by the reporting requirements of the federal Emergency Planning and Community Right-to-Know Act (EPCRA) must submit annual Tier II reports to the State Emergency Response Commission (SERC), the Local/Regional Emergency Planning Committee (LEPC/REPC), and the Local Fire Department. Tier II Reports for 2025 must be filed by March 1, 2026.” And the SERC’s own 13-page “Guide to EPCRA”, which sets out thresholds entirely in the federal terms — the EPA list of extremely hazardous substances and their threshold planning quantities — and names no Massachusetts figure. We looked for a state-specific number and did not find one; Massachusetts does have its own Right-to-Know law (M.G.L. c.111F), but that is workplace right-to-know, not a different section 312 threshold.
Where we read this
- Massachusetts SERC, Tier II reporting (read 2026-09-05): “submitting a report via the MA HazConnect Tier II system does NOT fulfill reporting requirements to R/LEPC and/or Fire Departments. Filers must still submit reports to their respective EPC and Fire Department per their respective reporting requirements”; “Reports must be submitted to the R/LEPC and fire department in the format they require”; “The Commonwealth of Massachusetts does not impose a filing fee however, some local jurisdictions do require them.”Checked 2026-09-08
