How New Hampshire takes it
New Hampshire files through its own online portal, run by AristaTek, and a Safety Data Sheet has to be attached for every chemical you report.
New Hampshire charges no filing fee — the state says so itself.
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. New Hampshire 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 New Hampshire asks for
Three things New Hampshire asks for that the federal form does not. A safety data sheet has to be attached for every chemical you report. You must list every chemical carrier the facility uses, together with the travel routes they take from a major highway — the state names Rt 93, Rt 89 and Rt 101 as examples, so collect this before you sit down. And the commission wants one email address per facility that someone actually watches. On the file question: we have found nothing from New Hampshire saying its portal will take a Tier2 Submit file. The formats it names for uploads are .pdf, .doc, .jpg and .xls, which read like attachments rather than the report itself — so plan on keying the data in and using our worksheet for that.
Does New Hampshire set its own limits?
New Hampshire'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.
New Hampshire applies the federal thresholds unchanged. What it adds is not a number but attachments: a safety data sheet for every chemical you report, and the list of chemical carriers with the routes they take from a major highway.
The words we read
US EPA, “State Tier II Reporting Requirements and Procedures” — New Hampshire section. EPA’s compilation states the submission route and any state-added fields; it records no state threshold below the federal 10,000 lb / 500 lb-or-TPQ tests. New Hampshire’s own Tier II Reporting Guidelines (firemarshal.dos.nh.gov), read 2026-09-07: the numbers there are the federal ones verbatim — hazardous chemicals requiring a safety data sheet at 10,000 pounds, extremely hazardous substances under EPCRA section 302 at the threshold planning quantity or 500 pounds whichever is less (“EHSs and their TPQs are listed in 40 CFR part 355, appendix A and appendix B”), gasoline at a retail station at “75,000 gallons (or approximately 283,900 liters)” and diesel at “100,000 gallons (or approximately 378,500 liters)” where the tanks were entirely underground and in compliance. New Hampshire sets no threshold of its own.

Where we read this
- NH Division of Fire Safety, “Tier II Reporting Guidelines” and the SERC pages (firemarshal.dos.nh.gov), read 2026-09-06 and 2026-09-07: a copy of the report is filed with the SERC through the online portal, due March 1; “preferred file formats are .pdf, .doc, .jpg, and .xls”. “New Hampshire requires that a Safety Data Sheet (SDS) be submitted for all reported chemicals. These are added as attachments.” · “New Hampshire requires that all chemical carriers used by the facility be listed along with travel routes from a major highway (e.g., Rt 93, Rt 89, Rt 101, etc.).” · “The State Emergency Response Commission (SERC) requires a consistent and monitored email address for each facility.” · “There are no Tier II reporting fees.” · “Reports are due by March 1st of the following year.” · “Facilities are also required to submit their Tier II reports to the local fire department and the Local/Regional Emergency Planning Committee (LEPC/REPC).”On the file question: nothing on those pages mentions Tier2 Submit or a .t2s upload. EPA’s state list only says New Hampshire “only accepts electronic submissions via the NH Tier II portal”. The portal is AristaTek’s — the same vendor as Wyoming, where .T2S upload is documented — but that is our inference, not New Hampshire’s statement, so we do not claim it and tell you to type it in.Checked 2026-09-07
