Form R Reporting: Thresholds, Exemptions, and Penalties

If your facility handles listed toxic chemicals above certain quantities, EPA Form R reporting is the annual filing that tells the government, and the public, what you released and where it went. The form is due July 1 each year and covers the previous calendar year’s activities.¹ It exists because Section 313 of the Emergency Planning and Community Right-to-Know Act created the Toxics Release Inventory to make chemical releases visible to communities and regulators.² Miss it and civil penalties now run above $71,000 per violation per day, so the details matter.

Who Has to File

A facility owes a Form R only when three conditions line up in the same year. Fall short on any one and that chemical, for that year, drops out.

The facility’s primary six-digit NAICS code falls within a TRI-covered sector. That includes all manufacturing, certain mining, coal- or oil-fired electric utilities, commercial hazardous waste treatment, chemical wholesale distribution, petroleum bulk terminals, and solvent recovery. Federal facilities report regardless of NAICS code.³
The facility has 10 or more full-time employees, measured as 20,000 total work hours across everyone on payroll for the year. Part-time and seasonal hours count.⁴
The facility manufactured, processed, or otherwise used a listed toxic chemical above the applicable threshold during the year.⁵

Mixed-use sites need one extra check. If a complex houses covered and non-covered operations, coverage depends on whether the covered establishments account for more than 50 percent of the site’s total value of products and services.⁴

Chemical Thresholds That Trigger a Report

For most listed chemicals, the thresholds are 25,000 pounds manufactured or processed during the year, or 10,000 pounds otherwise used.⁵ “Otherwise used” is the category for chemicals that don’t end up in a product, such as cleaning solvents consumed on site. You track manufacturing/processing and use quantities separately, because either path can trigger reporting on its own.

Persistent, Bioaccumulative, and Toxic Chemicals

Chemicals of special concern carry much lower thresholds because they persist in the environment and build up in living organisms. Lead and lead compounds report at 100 pounds. Mercury and mercury compounds report at 10 pounds. Dioxin and dioxin-like compounds report at 0.1 grams, the lowest threshold in the program.⁶

PFAS

Congress has been adding per- and polyfluoroalkyl substances to the TRI list through annual National Defense Authorization Acts. For reporting year 2025 (forms due July 1, 2026), 205 PFAS are reportable, and one more, sodium perfluorohexanesulfonate, is added for reporting year 2026.⁷ Each individually listed PFAS has a 100-pound reporting threshold.⁶ PFAS also cannot use the de minimis exemption, cannot be reported on the shorter Form A, and face limits on range reporting.⁸

The De Minimis Exemption and Its Big Exception

You don’t count trace amounts of a listed chemical in a mixture. If the chemical is present below 1 percent (0.1 percent for carcinogens), you can exclude that quantity when calculating whether you crossed a threshold.⁹ Carcinogen status is set by the National Toxicology Program’s Report on Carcinogens, IARC monographs, or OSHA’s list of regulated substances.

The exception is the one most likely to catch a facility off guard: the de minimis exemption does not apply to chemicals of special concern under 40 CFR 372.28, which includes every PBT chemical and every individually listed PFAS.⁹ For those, every pound counts toward the threshold regardless of the concentration in the mixture that brought it onto the site.

What Form R Asks For

Form R has two parts. Part I is facility-level information you complete once: TRI Facility ID number, parent company name, applicable NAICS codes, and contact details for both a technical representative and a public contact.¹⁰

Part II is completed separately for each chemical over threshold, and it is where most of the work sits. You account for on-site releases (fugitive air emissions, stack air emissions, discharges to water, and releases to land, including surface impoundments, landfills, and underground injection), off-site transfers with the name and address of each receiving facility, quantities recycled, burned for energy recovery, or destroyed on-site or off-site, and any source reduction activities you undertook. It is essentially a mass balance for each chemical: what came in, what went out, and where it ended up. The data is published, so accuracy matters.

Estimation Methods and Records

The EPA allows four ways to develop the release numbers. Direct measurement is preferred when the monitoring exists but rarely covers every release point. Mass balance calculations track inputs against outputs. Emission factors apply statistically derived averages from similar processes and equipment. Engineering calculations model releases from chemical properties, process conditions, and equipment specifications.

Whatever method you use, keep the supporting records for three years from the date you submit the report.¹¹ That means raw data, calculation worksheets, the emission factors you applied, and the reasoning behind the method you chose. An EPA audit asks not only what you reported but how you got there.

The Form A Shortcut

A facility that handles a listed chemical in large volumes but releases very little of it can file a Form A certification statement in place of a full Form R. Form A takes basic chemical identification and a signed certification instead of the detailed release accounting.

A chemical qualifies for Form A only when all of these are true:

The chemical is not listed as a chemical of special concern under 40 CFR 372.28, which rules out every PBT chemical and every individually listed PFAS.¹²
The facility manufactured, processed, or otherwise used no more than 1 million pounds of the chemical during the year.
The total reportable amount, meaning all environmental releases plus all quantities transferred off-site for disposal, treatment, recycling, or energy recovery, does not exceed 500 pounds.¹²

The test runs chemical by chemical. It’s common for a facility to use Form A for one chemical and full Form R for others in the same reporting year.

How to Submit

All TRI reporting goes through TRI-MEweb, the EPA’s web-based reporting tool, accessed through the Central Data Exchange.¹³ The software walks through each field and runs validation checks that flag obvious errors before you submit.

Before a facility can file, a designated certifying official must register a CDX account and complete an Electronic Signature Agreement. The signed ESA has to be mailed to the EPA’s data processing center and approved before the certifying official can sign anything. Processing can take up to five calendar days, so don’t leave it for late June.¹⁴

The deadline is July 1, covering the previous calendar year.¹ The certifying official signs a statement that the reported information is true, complete, and based on reasonable estimates from available data. The system returns instant confirmation of receipt.

Trade Secret Filings Are Different

Trade secret claims for chemical identity cannot go through TRI-MEweb. Those filings are submitted on paper in both a sanitized version (with the chemical identity redacted) and an unsanitized version, along with a substantiation form justifying the trade secret claim.¹⁵ The substantiation has to be refiled every reporting year, even if nothing has changed.¹⁶

Fixing a Report After You File

Errors after submission are handled through TRI-MEweb. A revision corrects information on a form that should have been filed; it uses the same certifying official process. A withdrawal removes a form that shouldn’t have existed at all, such as a case where recalculation shows the facility didn’t actually meet a threshold, or a chemical was reported by mistake.¹⁷ Once a withdrawal is certified, the EPA removes that chemical form from the TRI database.

Penalties and the Self-Disclosure Discount

The inflation-adjusted maximum civil penalty for TRI reporting failures is $71,545 per violation per day, effective January 2025.¹⁸ Each chemical you failed to report is a separate violation, and the daily clock runs on each one at the same time. A missed July 1 deadline on three reportable chemicals is three violations accruing in parallel.

The EPA’s voluntary self-disclosure policy offers up to a 75 percent reduction in penalties, but only when strict conditions are met. The discovery has to be voluntary rather than prompted by a government inspection, full disclosure to the EPA has to happen within 10 days of discovering the violation, the problem has to be corrected within 60 days, and the same violation cannot have occurred at the facility within the previous three years. Facilities that find prior-year gaps generally have more to gain from self-disclosing than from waiting.

Supplier Notification Is a Separate Duty

Section 313 also requires facilities that manufacture or process a TRI chemical and sell it in a mixture or trade name product to tell their customers that the product contains a listed chemical.² Downstream customers need the information to work out their own reporting obligations.

For most chemicals, the same de minimis cutoffs apply to supplier notifications (1 percent, or 0.1 percent for carcinogens). For chemicals of special concern, including PFAS, PBT chemicals such as lead and mercury, and dioxins, there is no de minimis exemption for supplier notifications.⁸ Any concentration triggers the notification.
