Tier II Chemical Reporting in Tennessee: Who Files & How

Short answer: if your Tennessee 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 Tennessee you file electronically through E-Plan, for the State Emergency Response Commission within the Tennessee Emergency Management Authority (TEMA). 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 Tennessee.

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 Tennessee

The trigger is federal and applies the same way in Tennessee 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 Tennessee 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.

Tennessee's State Emergency Response Commission (SERC) sits within the Tennessee Emergency Management Authority (TEMA) — the agency's name changed from “Agency” to “Authority” in July 2026, so you may see both on state pages.

Tennessee requires Tier II reports to be filed electronically through E-Plan (erplan.net), using its online Tier II filing section. Filing in E-Plan meets the SERC requirement only: TEMA's FAQ tells facilities to contact their LEPC to confirm whether it wants a paper copy, which you can print from E-Plan, and the same applies to your local fire department. Start from TEMA's Tier II chemical information page.

State systems and instructions can change year to year, so confirm current details with TEMA and the Tennessee SERC before you file.

The deadline

TEMA's FAQ: “Tier II reports are due by March 1st of each year” — for the previous calendar year, the same as the federal date. 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 Tennessee state fees?

The State of Tennessee does not charge a fee, but filing is not free. TEMA's FAQ: “E-plan charges $25.00 per facility to submit a Tier II report. The charge is paid directly to E-Plan, and the State of Tennessee has no additional charges.” Because E-Plan is the required system, budget $25 per facility each year.

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 E-Plan — 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.
