Tier II Chemical Reporting in New Hampshire: Who Files & How

Short answer: if your New Hampshire facility stores a hazardous chemical at or above its EPCRA reporting threshold — generally 10,000 pounds, or as low as 500 pounds for an Extremely Hazardous Substance — you must file an annual Tier II chemical-inventory report by March 1, covering the prior calendar year. It goes to your State Emergency Response Commission (SERC), your Local Emergency Planning Committee (LEPC), and your local fire department. In New Hampshire you upload a Tier2 Submit file with SDS attachments to the SERC's NH Tier II portal, run through the State Fire Marshal's Office; there is no state fee. The hardest part is compiling an accurate inventory with quantities — which is exactly what SDSentry ($24 per location per month) keeps current for you year-round. Here is how Tier II works in New Hampshire.

What Tier II is (and isn't)

Tier II is the annual chemical-inventory report required under Section 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA). Its purpose is to tell fire departments and emergency planners what hazardous chemicals are stored at your facility, in what quantities, and where, so responders know what they are walking into. It is a separate obligation from OSHA Hazard Communication — the same chemicals on your shelves, but a different law and a different audience. Meeting your HazCom duties does not satisfy Tier II, and vice versa.

Who has to file in New Hampshire

The trigger is federal and applies the same way in New Hampshire as everywhere else. You must file Tier II if any hazardous chemical for which you are required to keep a safety data sheet is present at your facility at or above its reporting threshold at any point during the year:

Quantities are based on the maximum amount present at any one time, aggregated across the facility. A small clinic or shelter often stays under these limits, but bulk propane or diesel tanks, stored fuel, pool and spa chemicals, fertilizer, or a large supply of a single disinfectant can push you over — and EHS thresholds are low enough that a modest amount of the wrong chemical can trigger a report.

Where New Hampshire facilities submit

EPCRA sends every Tier II report to three places: your State Emergency Response Commission (SERC), your Local Emergency Planning Committee (LEPC), and your local fire department.

New Hampshire's Tier II program is run by the Division of Fire Safety, State Fire Marshal's Office, for the NH State Emergency Response Commission. The Division: “Facilities should download the latest version of the EPA Tier2Submit software, create a submission, and upload the submission to the NH Tier II portal.”

New Hampshire asks for more than the federal form: “New Hampshire requires that a Safety Data Sheet (SDS) be submitted for all reported chemicals,” “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.),” and “a consistent and monitored email address for each facility.” The portal covers only the SERC: “Facilities should continue to submit their Tier II Submit files to their LEPC and Fire Departments.” If you stop needing to file, send the SERC a letter on letterhead saying you no longer have a reportable quantity on site. Start from the Division's Tier II reporting guidelines.

State systems and instructions can change year to year, so confirm current details with the NH State Fire Marshal's Office (NHTier2@dos.nh.gov) before you file.

The deadline

Reports are due by March 1 each year for the previous calendar year. The Division: “Any extension for filing deadline must come from EPA.”

Are there New Hampshire state fees?

No. The Division of Fire Safety: “There are no Tier II reporting fees in New Hampshire.”

What to have ready before you file

The report itself is mostly a structured list. What slows people down is assembling accurate underlying data. Before you start, have on hand:

If you keep a current SDS library and a per-location inventory with quantities throughout the year, the February scramble largely disappears. See our guide on building a chemical inventory from scratch for a starting point.

How SDSentry helps

SDSentry tracks quantity and unit per item in your per-location inventory, flags items over a threshold you set, and exports an EPCRA Tier II CSV so your preparer is not rebuilding the inventory by hand each February. It keeps a current SDS on file for every product, which is where most of the hazard and storage details on the report come from. It will not submit the report for you — you still file through Tier2 Submit and the NH Tier II portal — but it turns the worst part, compiling and maintaining the data, into a download. Pair it with our HazCom compliance checklist so your OSHA and EPCRA obligations stay covered at the same time.

Educational information only, not legal or compliance advice. Tier II thresholds, deadlines, submission methods, and any state fees change, and New Hampshire's specific process is set by the state. Verify your obligations with the NH State Fire Marshal's Office (NHTier2@dos.nh.gov), and with EPA's EPCRA resources at epa.gov/epcra, before you file — and consult a qualified professional for your situation.
