Tier II Chemical Reporting in Indiana: Who Files & How
Short answer: if your Indiana 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 Indiana you file through Tier II Manager (Hazconnect), run by the Indiana Department of Homeland Security (IDHS) for the Indiana Emergency Response Commission. 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 Indiana.

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 Indiana
The trigger is federal and applies the same way in Indiana 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:
- 10,000 lbs for most hazardous chemicals (those that require an SDS).
- 500 lbs — or the chemical's Threshold Planning Quantity, whichever is lower — for Extremely Hazardous Substances (EHSs) on EPA's list.
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 Indiana 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.
Indiana's SERC is the Indiana Emergency Response Commission (IERC), part of the Indiana Department of Homeland Security (IDHS). IDHS runs Indiana's own online system, Tier II Manager (also called Hazconnect), at tier2.dhs.in.gov. IDEM, the state environmental agency, offers EPCRA assistance but is not where Tier II reports go.
Online submission is required, and one submission covers all three recipients: the IERC's guidance says online submission “satisfies the notification requirement to the SERC, LEPC, and jurisdictional fire department.” Registration and instructions are on IDHS's Tier II Manager page. Fees are paid online through the same Hazconnect account.
State systems and instructions can change year to year, so confirm current details with the Indiana Emergency Response Commission at IDHS before you file.
The deadline
The Indiana Tier II deadline is March 1 every year, for the previous calendar year — the same as the federal date. The state filing fee is also due by March 1 (see below). Build in time before the deadline to gather quantities and have your preparer review them, because the last week of February is a poor time to discover your inventory list is out of date.
Are there Indiana state fees?
Yes. Indiana Code 13-25-2-10.4 (IERC fee summary (checked Oct 2026)) sets an annual per-facility fee, paid through Hazconnect:
- $200 if at least 1,000,000 pounds of any hazardous chemical was present at one time during the preceding year.
- $100 if one or more hazardous chemicals were present at or above the reporting thresholds, but under 1,000,000 pounds.
- $50 for a facility reporting only because of underground storage tanks.
A facility in the $100 category that has not paid by March 1 owes a $20 late fee, which grows monthly under the statute. Federal and state agencies, state educational institutions and political subdivisions are exempt. IDHS says it will stop accepting paper checks from January 1, 2027.
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:
- A complete chemical inventory for the location, with the product name and chemical identity for each item.
- The maximum quantity on site during the year and the average daily quantity, with units.
- Storage details — container type, pressure, temperature, and the specific location or building.
- Hazard information from each product's safety data sheet.
- Facility identifiers, emergency contacts, and (where required) latitude and longitude.
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 Tier II Manager (Hazconnect) — 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.

Frequently asked questions
Who do I send my Tier II report to in Indiana?
Indiana facilities file online through Tier II Manager (Hazconnect), run by the Indiana Department of Homeland Security for the Indiana Emergency Response Commission. Per the IERC, that online submission satisfies the notification requirement to the SERC, the LEPC and the jurisdictional fire department.
When is the Tier II deadline in Indiana?
March 1 each year, covering the prior calendar year, the same as the federal EPCRA deadline. Indiana's state filing fee is also due by March 1.
What are the Tier II reporting thresholds?
You report if a hazardous chemical that requires a safety data sheet is on site at or above 10,000 pounds at any time during the year, or at or above 500 pounds — or the Threshold Planning Quantity, whichever is lower — for an Extremely Hazardous Substance. Quantities are the maximum amount present at any one time.
Is there a Indiana state fee for Tier II?
Yes. Under Indiana Code 13-25-2-10.4 the annual fee is $200 for facilities with at least 1,000,000 pounds of a hazardous chemical, $100 for other facilities over the reporting thresholds, and $50 for facilities reporting only underground storage tanks. A $20 late fee applies to the $100 category if unpaid by March 1. Government agencies and political subdivisions are exempt.
