TRI Reporting and EPA Form R: A California Facility’s Guide
If you’re trying to figure out whether your California facility has to file an EPA Form R this year, who can prepare it, or what happens if you’ve missed one in a prior year, this page is the starting point.
If you’re trying to figure out whether your California facility has to file an EPA Form R this year, who can prepare it, or what happens if you’ve missed one in a prior year, this page is the starting point. We’ll cover what TRI reporting is, who’s required to file, how Form R has to line up with the other reports your California facility already files, and how CDMS prepares and files it for facilities across the state.
And if you’re not sure whether any of this applies to you, that’s normal. Most facilities that call us about toxic release inventory reporting either just got a letter from EPA, just realized one of their chemicals is on the TRI list, or are working through the question for the first time. Each path has a different answer, and we’ll walk you through the one that fits.
What TRI Reporting Is
The Toxics Release Inventory is a federal program under EPCRA Section 313 (the Emergency Planning and Community Right-to-Know Act, Title III of SARA 1986) and the Pollution Prevention Act, codified at 40 CFR Part 372. Covered facilities file one EPA Form R per reportable chemical each year, by July 1, for chemical activity during the prior calendar year.
A Form R is a mass balance. You account for how much of a listed chemical entered your facility and where every pound of it went: to air, to water, to land, to off-site transfers, to recycling, to energy recovery, or to treatment. The numbers come from purchase records, SDSs, waste manifests, wastewater and stormwater monitoring data, air emissions estimates, and recycling records. The report is filed electronically through EPA’s Central Data Exchange (CDX). After it’s filed, EPA publishes it. Anyone with an internet connection can look up what your facility reported.
There is no separate California TRI report. California facilities file the same federal EPA Form R as everyone else, through CDX, and the state receives that data directly from EPA through the State TRI Data Exchange. You file once, federally, and California gets its copy automatically. The federal TRI list covers more than 650 chemicals and chemical categories, and EPA updates it periodically.
For a plain-language walkthrough of the report itself, see what EPA Form R is and how TRI reporting works.
Who Has to File
A facility is covered by TRI when all three of these are true at the same time:
| Trigger | Threshold | Who Enforces |
|---|---|---|
| Employees | 10 or more full-time equivalents (20,000+ total work hours in the calendar year, all employees combined) | US EPA |
| Industry | A covered NAICS code (the federal industry classification system): primarily manufacturing (NAICS 31-33) and chemical distribution (NAICS 424), plus a handful of others including electric utilities, mining, and hazardous waste management | US EPA |
| Chemical use | More than 25,000 lbs manufactured, processed, or imported, OR more than 10,000 lbs “otherwise used,” of a listed TRI chemical in the calendar year | US EPA |
PBT chemicals (persistent, bioaccumulative, and toxic) have much lower thresholds: lead at 100 lbs, mercury at 10 lbs, dioxin compounds at 0.1 grams. PFAS chemicals (per- and polyfluoroalkyl substances, the so-called “forever chemicals”) were added to the TRI list in recent years, and EPA continues to add more each cycle.
If even one of the three triggers isn’t met, the facility doesn’t have to file Form R for that year. But “not met” has to be documented. EPA expects facilities to know where they sit and to keep the records that support a no-file decision.
This is where most of the confusion sits. Facilities that don’t think of themselves as “chemical companies” can still cross thresholds quickly. A metal fabricator processing 200,000 lbs of stainless steel a year puts roughly 33,000 lbs of chromium through the operation. That’s over the 25,000-lb processing threshold, even though no one ever bought a drum of chromium. (The nickel in the same steel comes in lower, around 8,000 lbs, and may or may not cross depending on the alloy and total throughput.) A circuit-board assembler running solder pots crosses the 100-lb lead threshold faster than people expect. Facilities that neutralize or treat nitric acid may generate nitrate compounds, and the acid and the nitrate compounds should be evaluated separately. We go through the chemical-side detail in our piece on commonly missed TRI Form R chemicals.
Why California Facilities Call Us About Form R
Most of the calls we get fall into one of four patterns. If any of these sound familiar, you’re in the right place.
“We didn’t know we had to report.”
A facility realizes, often after reading something in a trade publication or hearing from a peer, that one of the chemicals they use crosses a TRI threshold. They’ve never filed. They want to know what to do.
“EPA flagged a discrepancy.”
EPA and other reviewers may compare Form R submissions against AER (Air Emissions Report) filings, hazardous waste manifests, and wastewater monitoring data. When the numbers don’t line up, the facility can get a letter. It now has to either explain the gap or refile.
“Is this already covered by my ongoing service?”
Facilities on an ongoing Comprehensive Compliance Management plan want to confirm whether Form R is part of what they’re already paying for, or whether it’s an add-on for the year.
“We already handle it internally.”
A mature manufacturer has run TRI internally for years with spreadsheets and a designated coordinator. They want a second set of eyes, or they want to hand it off so the coordinator can focus elsewhere.
We work with all four. The first two are time-sensitive: a missed report carries per-chemical, per-year penalty exposure, and EPA discrepancy letters have response windows. The second two are calendar-driven and can be planned around the standard January-to-July cycle.
The Three Form R Services We Provide
Form R isn’t one service. It’s three, and most facilities need a clear answer on which one applies before any work starts.
Form R Evaluation (Threshold Determination)
If you don’t know whether you have to file, we evaluate. Our consultants review your facility’s chemical inventory, SDSs, purchase records, and process flow against the current federal TRI list. We calculate how much of each potentially reportable chemical passes through the facility in a year and compare it to the federal thresholds (and the PBT thresholds, which are easy to overlook).
The output is a documented determination: either a list of reportable chemicals that need a Form R, or one of three “No Form R” letters explaining why no filing is required (NAICS code not covered, employee hours below the trigger, or chemical quantities below threshold). The letter goes in your file. If EPA ever asks why you didn’t file, you have the answer ready.
Form R Preparation and CDX Filing
If you have one or more reportable chemicals, we prepare the Form R and file it through CDX. For each chemical, that includes:
- Threshold calculations: converting gallons to pounds using specific gravity, accounting for solution concentrations, handling alloys and metal compounds, and applying the de minimis rules (1% for most chemicals, 0.1% for carcinogens).
- Release calculations for every pathway: air emissions, wastewater discharges, stormwater runoff, land application, off-site transfers, recycling, energy recovery, and treatment.
- Cross-checks against your AER, waste manifests, and monitoring data so the numbers are consistent across reports.
- CDX upload, certifying-official signature coordination, and the validation report you’ll keep for your records.
The deliverable set includes a cover letter, the draft Form R for your review before submission, the threshold and release calculation spreadsheets, a waste tracking log, and the CDX validation report after filing.
Form R Self-Disclosure
If you’ve realized you should have been filing for one or more past years and you haven’t been, EPA has an audit-policy pathway that, when its conditions are met, can reduce or eliminate the gravity-based portion of the penalty. The pathway is narrow and time-sensitive. The facility has to discover the issue itself, not through an EPA inspection. From there: disclose to EPA within 21 days of discovery, and correct the issue (which can include filing the missing reports) within 60 calendar days in most cases.
We’ve walked facilities through this process. The first step is usually a phone call: we ask what you know, what records you have, and how many years are in play. From there we scope the disclosure and the back-year filings together.
How CDMS Prepares Form R
Form R is a records-based report, and we prepare it from your data rather than from a software tool that reads your numbers and assumes the rest. The work runs on your SDSs, purchase and usage records, waste manifests, wastewater and stormwater monitoring data, air emissions estimates, and recycling records. Because the program is federal and the work is built from documentation, most of it happens without a site visit.
Every annual engagement starts with a fresh evaluation against the current EPA chemical list, because the list changes every year. PFAS additions over the last several cycles are the most visible example; smaller revisions happen quietly each year. We confirm your chemical inventory, collect Supplier Notification documentation (required under 40 CFR 372.45), and identify anything new before threshold work begins.
You receive a draft for review well ahead of July 1, along with the calculation workbooks and the CDX validation report you’ll keep for your records. The deliverables on every engagement: threshold determinations, release calculations, the filed Form R, the cover letter, a waste tracking log, and the validation receipt from CDX.

How Form R Connects to Your Other Reports
Form R doesn’t sit alone. Reviewers may compare it against your other filings, and the same data often feeds several reports at once. A few connections worth knowing:
Air Emissions Report (AER).
California facilities subject to local air district reporting file an AER each year. The chemical-specific emissions on the AER should match what shows up in the air-release columns of your Form R, and inconsistencies between the two can prompt questions. See our annual emissions report guide.
Hazardous Materials Business Plan and CERS.
The chemical inventory you maintain in CERS (the state’s online environmental reporting portal) is the starting point for a Form R evaluation. If a chemical isn’t in CERS, it usually isn’t on the Form R either. See our HMBP and CERS submittal guide.
Biennial Hazardous Waste Report.
Waste-stream quantities on the biennial report should be consistent with off-site-transfer and on-site-treatment quantities on Form R. See our hazardous waste management guide.
Wastewater monitoring data.
Concentration data from self-monitoring reports feeds the water-release calculations on Form R. See our industrial wastewater discharge permit guide.
This is the heart of how we approach Form R: it’s one report in a connected set, not a standalone form. When all of these reports are managed by one firm, the inconsistencies that trigger EPA inquiries get caught before they go out the door. A vendor who only touches your Form R, or a software tool that only fills it in, sees just the one report, and that’s where the discrepancy letters come from.
Frequently Asked Questions
When is EPA Form R due?
Form R is due July 1 each year for chemical use during the prior calendar year.
What chemicals are on the TRI list?
The federal TRI list includes more than 650 chemicals and chemical categories, and EPA updates it periodically. The categories include chemicals that cause cancer, chemicals with chronic or acute health effects, and chemicals with significant environmental effects. PBT chemicals (like lead, mercury, and dioxin compounds) have lower thresholds, and PFAS chemicals continue to be added.
What’s the penalty for not filing?
EPA can issue penalties on a per-chemical, per-year basis, and exposure adds up quickly when multiple years or multiple chemicals are involved. The EPA audit policy can reduce or eliminate gravity-based penalties when the facility self-discloses, notifies EPA within 21 days of discovery, and corrects the issue (which can include filing the missing reports) within 60 calendar days, provided the policy’s conditions are met. Most facilities we evaluate get a clear answer quickly on whether they have exposure, and on what to do about it if they do.
Do I have to file if I just store chemicals and never use them?
Possibly. EPA treats some storage and distribution activities as “otherwise using” or “processing,” depending on what happens to the chemical and how it moves through the facility. Factory-pack chemical distributors who never open the containers can still trigger Form R obligations. The threshold determination is what answers this question for your facility.
Does California require its own TRI filing?
No. California does not have a separate state TRI report. California facilities file the federal EPA Form R through CDX, and California receives that data directly from EPA through the State TRI Data Exchange. You file once, federally; there is no second filing to submit to the state.
Does CDMS handle PFAS reporting?
Yes. PFAS chemicals are part of the standard Form R workload now. The list of reportable PFAS continues to grow, which is one reason every annual engagement starts with a fresh evaluation against the current year’s chemical list.
