The chemical inventory the state wants by March 1.
If your site stores hazardous chemicals above the reporting amounts, federal right-to-know law makes you file an annual Tier II inventory with the state, the local emergency planning committee, and the fire department. RuleRobin works out what is reportable and builds the report.
Texas (TCEQ STEERS) first, then more states. Enter your details to be first in line when it opens.
Tier II reports are due March 1 each year, for the prior calendar year, and the obligation is annual and non-negotiable. Enforcement is real: one fertilizer facility paid about $62,985 for failing to file for its chemicals over two years, and penalties for false information can reach tens of thousands of dollars per day.
Who has to file
It comes down to how much you store.
| Threshold | Applies to | What it means |
|---|---|---|
| 10,000 lb | Most OSHA hazardous chemicals | The general reporting threshold for a hazardous chemical that needs a Safety Data Sheet. |
| 500 lb / TPQ | Extremely Hazardous Substances | 500 pounds or the substance's Threshold Planning Quantity, whichever is lower. |
| 75,000 gal | Retail gasoline | Underground tanks at a retail fuel site have their own higher threshold. |
| 100,000 gal | Retail diesel | Underground diesel at a retail site is reported above this amount. |
Typical filers: gas stations and fuel retailers, farms and fertilizer dealers, warehouses and distributors, water and wastewater utilities, manufacturers, and data centers with battery banks and diesel gensets.
An annual headcount of the hazardous chemicals on your site.
Tier II comes from Section 312 of the federal Emergency Planning and Community Right-to-Know Act, carried out through the EPA rule at 40 CFR Part 370. If your workplace has to keep a Safety Data Sheet for a chemical under OSHA rules, and you store enough of it, you report it once a year: how much is on site at the most, the daily average, how many days, how it is stored, and where. It goes to the state emergency response commission, the local planning committee, and your fire department.
Not just the file. The whole yearly chore.
EPA publishes a free desktop tool that produces the raw file, and it works if you already know your thresholds and hazard classifications. We will say that plainly. RuleRobin is for the operator who files once a year and does not want to relearn it every February.
- Applies the reporting thresholds to decide what is reportable, and what is not.
- Looks up Extremely Hazardous Substance status and planning quantities for you.
- Builds the report to the state's required format and validates it before you submit.
- Remembers your facility, contacts, and chemicals so next year is a review, not a rebuild.
- Sends the reminders so March 1 does not sneak up on you.
- Keeps an audit trail of what you entered and which thresholds applied.
Straight about it
You certify it. We prepare it.
- No licensed preparer is required for Tier II. The facility owner, operator, or an authorized representative signs the certification.
- You attest the inventory is true and complete. Confirm your quantities and the reportable calls before you submit.
- RuleRobin is a preparation and filing aid, not your compliance officer, and it is not affiliated with the EPA or any state agency.
- State filing fees are set by the state and passed through to you; we do not mark them up.
