Tier II Chemical Reporting in Ohio: Who Files & How

Short answer: if your Ohio 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 for the prior calendar year. In Ohio those reports go to the State Emergency Response Commission (SERC), your Local Emergency Planning Committee (LEPC), and your local fire department. The hard part is compiling the inventory, and that is exactly what SDSentry ($24.99 per location per month) keeps current for you, so February isn't a scramble. Here's how Tier II works in Ohio.

What Tier II is (and isn't)

Tier II is an annual chemical-inventory report required under the federal Emergency Planning and Community Right-to-Know Act (EPCRA, Sections 311–312). Its purpose is emergency response: it tells fire departments and local planners what hazardous chemicals are stored at your site, in what quantities, and where, so responders aren't walking into the unknown. It is separate from OSHA HazCom — the same chemicals are involved, but HazCom protects your employees through labels, training, and safety data sheets, while Tier II informs the community and emergency responders. Meeting one obligation does not satisfy the other.

Who has to file in Ohio

The trigger is federal and applies the same in Ohio as everywhere else. Any facility required to keep a safety data sheet for a hazardous chemical must file Tier II if that chemical is present on site at or above the reporting threshold at any point during the calendar year. The general thresholds are:

• 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 facility that briefly held a large delivery still counts that peak amount.

Where Tier II reports go in Ohio

EPCRA requires you to send the report to three recipients: your State Emergency Response Commission, your Local Emergency Planning Committee, and the fire department with jurisdiction over your facility. In Ohio:

• The Ohio State Emergency Response Commission (SERC) is established under Ohio Revised Code Chapter 3750. It is the state-level recipient for Tier II information.
• The Ohio SERC is supported by the Ohio Environmental Protection Agency (Ohio EPA), which administers the state's Tier II program and provides the Ohio SERC information page.
• Your county LEPC and your local fire department are the other two required recipients.

Ohio accepts electronic Tier II submission through Tier2 Submit, EPA's free desktop application. Prepare your chemical inventory in Tier2 Submit and file the resulting report to the Ohio SERC via the Ohio EPA, then distribute copies to your county LEPC and local fire department. Start from the official Ohio SERC page for the current submission instructions. Filing details and any state-specific forms can change from year to year, so confirm the current filing instructions and recipients with the Ohio SERC before you file.

The deadline

Tier II reports are due annually by March 1 and cover the previous calendar year. Ohio follows the federal March 1 due date. That single date is easy to miss because the work behind it — knowing exactly what was on site and at what peak quantity last year — takes time to assemble if you start in February. Treat the inventory as something you maintain year-round, not something you reconstruct.

Do small Ohio facilities usually hit the threshold?

Often they don't. A typical clinic, shelter, shop, or small office stocks cleaners and disinfectants in quantities well under 10,000 lbs. But it's worth checking the items that add up: bulk pool or spa chemicals, large propane or diesel tanks, stored fuel, fertilizer, or a big bulk supply of a single product. EHSs have far lower thresholds, so a relatively small amount of the wrong chemical — for example certain disinfection or water-treatment chemicals — can trigger reporting on its own. The only way to know is to track quantities and units per item.

How SDSentry helps Ohio facilities

SDSentry tracks quantity and unit per item in your per-location chemical inventory, flags items over a threshold you set, and exports an EPCRA Tier II CSV — so your preparer isn't rebuilding the inventory by hand each February. It keeps a current safety data sheet on file for every product, which is the same library your HazCom program needs, so the data behind both obligations lives in one place. SDSentry won't file with the Ohio SERC for you, but it turns the worst part — compiling and quantifying the inventory — into a download. It's a flat $24.99 per location per month with unlimited users and a 14-day free trial. Pair it with our HazCom compliance checklist to keep both your Tier II and your OSHA obligations covered.
