Hazmat Report: Filings, Tier II Contents, and Penalties

Hazmat reporting requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA) fall into two buckets: annual inventory filings for what your facility stores or releases, and immediate notifications when a chemical release crosses a reportable threshold. The two annual filings are the Tier II hazardous chemical inventory (due March 1) and the Toxic Release Inventory, or TRI, report (due July 1). Missing either can cost up to $25,000 per violation per day, and a knowing failure to report a release is a criminal offense.

The Two Annual Filings and When They’re Due

If your facility is required to keep a Safety Data Sheet (SDS) for a chemical under OSHA’s Hazard Communication Standard, and that chemical is present above EPCRA’s threshold quantity at any single moment during the year, you owe a Tier II report covering the prior calendar year.¹ The deadline is March 1, and the form goes to three recipients: the State Emergency Response Commission (SERC), the Local Emergency Planning Committee (LEPC), and the local fire department.²

The threshold is 10,000 pounds present at the facility at one time for most hazardous chemicals.³ Buying more than 10,000 pounds across the year doesn’t trigger the requirement if you never have that much on-site at once. For Extremely Hazardous Substances (EHSs), the threshold drops to 500 pounds or the chemical’s Threshold Planning Quantity, whichever is lower.⁴

Most facilities file electronically using the EPA’s free Tier2 Submit software. Only the current year’s version generates valid files, so download the new release each reporting cycle. Some states and tribes maintain their own portals, so check with your state agency for the exact submission path.²

The TRI report, due July 1, is a separate filing that tracks releases of listed toxic chemicals into the environment along with waste management and pollution prevention activity.⁵⁶ A facility owes TRI reporting only if it meets all three of these tests:

Ten or more full-time employees, or the equivalent in total hours.
Operation in a TRI-covered industry sector, which includes manufacturing, mining, electric utilities, and certain other sectors.
Manufacturing or processing at least 25,000 pounds of a listed toxic chemical during the year, or otherwise using at least 10,000 pounds.⁷

The manufacturing/processing versus “otherwise using” distinction changes which threshold applies. A chemical incorporated into your product is manufactured or processed (25,000 pounds); the same chemical used as a cleaning solvent is otherwise used (10,000 pounds).⁸

What a Tier II Report Must Contain

For each reportable chemical, the Tier II form requires a specific data set designed for emergency responders and planners.⁹

Chemical identity, including the name as it appears on the SDS and the CAS registry number.¹⁰
Physical and health hazard categories, based on the SDS.
Maximum quantity present on any single day and average daily amount, both reported using EPA’s standardized range codes.
Storage type (above-ground tank, steel drum, cylinder, and so on) and a precise location within the facility, which can include a site plan with coordinates.

Location detail matters. A site plan that pinpoints which building or lot holds which chemical is what first responders actually use. “Warehouse area” is not enough.

What You Don’t Have to Report

Several categories of chemicals don’t count toward Tier II thresholds. Consumer products used in the same form and concentration as those sold to the general public are exempt.¹¹ A bottle of household bleach in the janitor’s closet doesn’t need reporting. Solid manufactured items whose end use depends on their shape rather than their chemistry are also exempt: bricks, sheet metal, and plastic pellets are typical examples.¹²

The solids exemption vanishes the moment your operation changes the item in a way that creates chemical exposure. Cutting bricks generates silica dust; grinding sheet metal produces metal fumes. Once that happens, the material counts toward the threshold. Machine shops and construction operations that routinely cut, weld, or grind manufactured materials often trip this line without realizing it.

Reporting a Release: The Incident-Side Obligation

When a release of a hazardous substance or EHS meets or exceeds its Reportable Quantity within a 24-hour period, you must immediately notify the SERC (or Tribal Emergency Response Commission) and the LEPC (or Tribal Emergency Planning Committee) for any area likely affected.¹³ For CERCLA hazardous substances, you must also immediately call the National Response Center at 800-424-8802.¹⁴

Give as much of the following as you know, but don’t delay the call to gather it:¹⁵

The chemical name and whether it is an EHS.
An estimate of the quantity released.
When the release occurred and how long it lasted.
Whether it went to air, water, soil, or some combination.
Any known acute or chronic health effects and advice on medical attention.
Precautions the surrounding community should take, including possible evacuation.
A contact name and phone number for follow-up.

A written follow-up report to the SERC and LEPC is required as soon as practicable after the initial call.¹³ There is no fixed day count; the EPA expects it promptly as more information becomes available. The written report updates the phone-call information and adds three items: the actions taken to respond to and contain the release, any known or anticipated health risks, and advice regarding medical attention for exposed individuals.¹⁶ If health risks develop or the release turns out to be larger than first estimated, updated notices are required.

Routine, Predictable Releases

Facilities with releases that are continuous and stable in quantity and rate, occurring as part of normal operations or treatment processes, can elect to report under the Continuous Release Rule rather than treating each occurrence as a new emergency.¹⁷ Examples include radon emissions from a stockpile running 24 hours a day or benzene releases during polymer production. The process starts with an initial telephone notification and an initial written report, then shifts to an annual anniversary report. A significant increase in quantity or a change in release source resets the process and must be reported as a new release.

Penalties for Missing a Report

Civil penalties for failing to file Tier II or TRI reports run up to $25,000 per violation, with each day of continued non-compliance counted as a separate violation.¹⁸ Failing to submit SDS information under Section 311 caps at $10,000 per violation. These base amounts get periodically adjusted for inflation, so the actual ceiling in a current enforcement action will be higher than the statutory floor.

Emergency release notification failures under Section 304 carry the harshest exposure. Administrative penalties reach $25,000 per violation for a first offense and $75,000 per day for subsequent violations. Knowing and willful failures to report a release are criminal offenses punishable by up to $25,000 in fines and two years in prison for a first conviction, rising to $50,000 and five years for repeat offenders.¹⁸

Trade Secret Claims

You can withhold the specific chemical identity of a substance from your EPCRA reports by claiming trade secret protection, but the claim isn’t automatic. You must submit a formal substantiation to the EPA answering six specific questions on the agency’s substantiation form and certifying the claims under penalty of perjury.¹⁹ Even with a valid claim, you still report everything else about the chemical: hazard categories, quantities, storage locations, and release data. Only the specific identity is withheld, and emergency responders and medical professionals can access it when needed for diagnosis or treatment.
