EPCRA — Community Right-to-Know & Toxic Release Inventory

The Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA, 42 U.S.C. §§ 11001–11050) gives communities, first responders, and local officials a legal pathway to learn what hazardous chemicals are stored and released nearby, and it requires emergency planning before accidents happen. Enacted as Title III of the Superfund Amendments and Reauthorization Act (SARA) after the Bhopal disaster, EPCRA created three core systems: emergency planning for facilities with extremely hazardous substances, release notification when reportable releases occur, and the Toxic Release Inventory (TRI), a public reporting database for listed toxic chemicals. The statute's power is partly regulatory and partly informational: it forces reporting, but much of its real-world effect comes from making chemical-risk data visible to the public.

42 U.S.C. § 11046 — Civil actions (any person may sue a facility owner for EPCRA violations; any person may sue EPA, SERC, or the Governor for failure to perform required duties)

How It Works

EPCRA's emergency planning framework (§§ 11001–11005) requires every state to establish a State Emergency Response Commission and divide the state into planning districts, each with a Local Emergency Planning Committee (LEPC). Facilities storing approximately 360 "extremely hazardous substances" above threshold quantities must notify their LEPC, designate an emergency coordinator, and participate in plan development. LEPCs produce comprehensive emergency response plans identifying local hazardous chemical sites, transportation routes, evacuation procedures, and training schedules. When a facility releases a listed hazardous substance above its reportable quantity, § 11004 requires immediate notification to the LEPC and SERC — including the chemical name, estimated quantity released, time and duration, media affected, health risks, and recommended precautions — followed by a written report as soon as practicable.

The Toxic Release Inventory (§ 11023) is EPCRA's most visible and consequential provision. Facilities in covered industries that manufacture, process, or use listed toxic chemicals above threshold quantities must file annual TRI reports with EPA and their state, covering releases to air, water, and land; off-site transfers; and other waste-management activity. The TRI chemical list is not static — EPA and Congress have continued adding substances including multiple PFAS. TRI's power comes not from direct emission caps within EPCRA itself but from public disclosure: companies don't want to top local pollution rankings, and communities don't want to learn about toxic releases only after an incident. That transparency pressure functions as a de facto enforcement tool independent of regulatory penalties. Citizen suits (§ 11046) reinforce this: any person can sue a facility for failing to comply with reporting requirements, or sue EPA or state agencies for failing to enforce — a private enforcement mechanism that environmental groups have used to compel reporting from non-compliant facilities.

How It Affects You

If you live near a factory, chemical plant, refinery, or industrial facility, EPCRA gives you a legal right to see exactly what toxic chemicals your neighbors are handling — and you don't need to file a FOIA request or hire a lawyer to get it. The Toxic Release Inventory (TRI) database at epa.gov/triexplorer lets you search by zip code, county, or facility name to see annual reports of chemical releases to air, water, and land. A plant releasing 100,000 pounds of a toxic chemical into the air each year is required to report that; you can download the data and compare it to neighboring facilities and to national averages. The Tier II reports — chemical inventories filed by March 1 each year — are submitted to your local fire department and Local Emergency Planning Committee (LEPC) and are available on request under EPCRA Section 324. Your LEPC publishes its emergency plan and maintains the Tier II data; find your LEPC through your state's emergency response commission. If you believe a facility is violating its reporting requirements — failing to disclose a chemical or under-reporting releases — you can file a citizen suit under Section 11046 without going through the government, potentially recovering civil penalties and attorney fees. Environmental groups like Earthjustice (earthjustice.org) and the Environmental Defense Fund (edf.org) have used EPCRA citizen suits to compel reporting from facilities that refused to disclose.

If you're a firefighter, EMT, or local emergency planner, EPCRA's annual Tier II reporting requirement (Section 312) is your primary tool for pre-incident intelligence. Facilities that store hazardous chemicals above threshold quantities — typically 10,000 lbs for general hazardous chemicals, lower for extremely hazardous substances — must file Tier II reports by March 1 with your fire department, your LEPC, and your state SERC. These reports identify every chemical stored on-site, the maximum quantity, storage location (indoor/outdoor, above/below ground, pressurized/non-pressurized), and the emergency contact. Most states now use the Tier2 Submit software or an online portal — your SERC can point you to the state submission system. If a facility releases a listed hazardous substance above its reportable quantity, it must notify your LEPC and the state SERC immediately (Section 304) — and must file a written follow-up within a specified period. Your LEPC is required to review its emergency plan annually and incorporate new Tier II data. If you're not already a participant in your LEPC, federal law requires that emergency responders have seats on it — contact your state SERC for information on joining.

If you operate an industrial facility covered by EPCRA — manufacturing, mining, electric utilities, and other covered SIC/NAICS codes — your compliance calendar has two hard annual deadlines that carry significant penalties for missing: Tier II reports due March 1 (Section 312, to fire departments and LEPCs) covering hazardous chemicals stored on-site during the prior year, and TRI Form R or Form A due July 1 (Section 313) covering releases and transfers of listed toxic chemicals above threshold quantities. The PFAS additions are the most significant recent compliance change — EPA has added over 200 PFAS to the TRI list under the FY2020 NDAA framework, with forms for reporting year 2025 due July 1, 2026. If your facility uses, processes, or manufactures PFAS above thresholds, you likely have new TRI obligations you may not have had previously. Civil penalties for EPCRA violations can reach tens of thousands of dollars per day per violation, and citizen groups (not just EPA) can file suit to compel compliance. Use EPA's TRI reporting forms and guidance at epa.gov/tri and the ECHO database at echo.epa.gov to understand your compliance obligations and compare your facility's TRI profile to peers. For small business compliance assistance, contact your state's small business environmental assistance program or EPA's SBEAP network (epa.gov/sbeap).

If you're an ESG analyst, impact investor, or corporate sustainability professional, TRI data is the most accessible, standardized, and historically deep environmental performance dataset available for U.S. industrial companies — going back to 1987. EPA's TRI Explorer (epa.gov/triexplorer) and Envirofacts database let you pull facility-level release data by year, chemical, media, and company. For publicly traded companies, cross-referencing TRI data with SEC filings (10-K environmental disclosures, material litigation sections) reveals whether companies are disclosing environmental risks proportional to their actual chemical release profiles. High TRI releases — particularly of carcinogens, endocrine disruptors, or newly regulated PFAS — signal potential regulatory enforcement risk, community health litigation exposure, and reputational liability. The TRI program's ongoing PFAS expansion and EPA's increased PFAS enforcement activity (2023-2026) mean that facilities with large PFAS TRI release profiles face rising regulatory and litigation risk. Third-party platforms like Enveritec and ESG Book aggregate TRI data into investment-ready formats; for raw data, EPA's Toxics Release Inventory Program provides bulk downloads at epa.gov/tri/tri-data-and-tools.

State Variations

EPCRA establishes a federal floor; many states go further:

Many states have enacted their own community right-to-know laws with additional chemical reporting requirements
State Tier II reporting thresholds may be lower than federal thresholds
Some states have expanded TRI-equivalent reporting to cover additional chemicals or smaller facilities
State emergency planning requirements may exceed EPCRA's minimum standards
California's Proposition 65 (Safe Drinking Water and Toxic Enforcement Act) provides a complementary right-to-know framework. See also RCRA / Solid & Hazardous Waste and Toxic Substances Control Act for related environmental statutes

Implementing Regulations

40 CFR Part 355 — Emergency Planning and Notification: the EPA regulation implementing EPCRA Sections 302-304, establishing the specific obligations that trigger emergency planning participation and defining when facilities must provide emergency notification of chemical releases. Key provisions:
- §§ 355.10–355.16 — Emergency planning requirements (Subpart B): a facility must comply with emergency planning if it has any extremely hazardous substance (EHS) present at or above its threshold planning quantity (TPQ); approximately 360 EHSs are listed in Appendices A and B with their TPQs (ranging from 1 pound for the most acutely toxic substances to 10,000 lbs+ for less hazardous materials); solid EHSs have dual TPQs — a higher TPQ applies to large particle non-reactive solids; TPQs are calculated by aggregating all quantities of the same EHS at the facility across all containers and locations (§ 355.14); mixtures are calculated by multiplying container volume by concentration to determine pounds of pure EHS (§ 355.13)
- § 355.20 — Required information submission: when a facility reaches a TPQ threshold, the owner/operator must notify the SERC (State Emergency Response Commission) and the LEPC (Local Emergency Planning Committee) for the emergency planning district; must designate a facility emergency coordinator and provide their name and phone number; must participate in the LEPC's emergency planning process on request; must advise the LEPC of any changes at the facility that affect emergency response
- §§ 355.30–355.43 — Emergency release notification (Subpart C): a separate — but related — obligation triggers when a facility releases (not merely stores) an EHS or a CERCLA hazardous substance above its reportable quantity (RQ) in a 24-hour period; §§ 355.33 and 355.60 clarify that EPCRA release notification runs parallel to CERCLA Section 103 notification — both must be made when a CERCLA hazardous substance is released above its RQ
  - § 355.40 — Two-stage notification: (1) Immediate oral notification must be made to the LEPC emergency coordinator and the SERC immediately after discovery of the release; (2) a written follow-up notification must be submitted as soon as practicable; the follow-up must describe: the chemical identity, estimated quantity released, time and duration, media affected (air/water/land), health risks, precautions to be taken, and the point of contact at the facility
  - § 355.42 — Notification recipients: the LEPC of every area likely to be affected by the release; the SERC of every state likely to be affected; the NRC (under CERCLA notification)
  - § 355.31 — Exemptions from notification: releases exempt from notification include: federally permitted releases; continuous releases (with prior notification); and releases to an on-site structure resulting in no exposure to the environment or individuals beyond the facility boundary
- § 355.61 — Key definitions: "Extremely hazardous substance (EHS)" means any chemical listed in Appendix A or B; "Reportable quantity (RQ)" means the quantity of each EHS whose release triggers emergency notification; "Facility" means all buildings, equipment, structures, and other stationary items at a single site owned by the same entity; animal waste from livestock operations is specifically excluded
Part 355 is the regulatory implementation of the "first responder's right to know" — it ensures that local fire departments, emergency medical services, and LEPCs receive advance information about hazardous chemicals stored nearby and immediate warning when a release occurs. The dual structure (planning threshold/TPQ for pre-incident planning + reportable quantity/RQ for incident notification) means some facilities trigger planning requirements without ever having a reportable release, while some releases are reportable even if the facility did not previously have a planning obligation. Facilities with EHSs on-site must familiarize themselves with both their SERC and their LEPC contacts before an incident occurs — waiting until a release happens to find contact information is both a compliance failure and a public safety risk.
40 CFR Part 370 — Hazardous chemical reporting (Tier I/II reporting, material safety data sheet submissions, threshold quantities)
40 CFR Part 372 — Toxic Chemical Release Reporting — Community Right-to-Know: the EPA implementing regulation for EPCRA Section 313, the Toxic Release Inventory (TRI). Part 372 defines which facilities must report, which chemicals must be reported, and how reports are filed:
- § 372.22 — Covered facilities: a facility must report if it: (1) is in a covered industry (SIC codes 20-39 manufacturing, plus metal/coal mining, electric utilities, hazardous waste treatment, and others); (2) has 10 or more full-time employee equivalents; and (3) manufactures or processes a listed toxic chemical above 25,000 lbs/year or otherwise uses it above 10,000 lbs/year; approximately 22,000+ facilities file TRI reports annually
- § 372.30 — Annual report (Form R): the annual TRI report due July 1 must include maximum on-site chemical quantity, total releases to air/water/land (both routine and accidental), off-site transfers to disposal or recycling, and source reduction activities; facilities meeting lower-use thresholds may file the simpler Form A (quantity data only, no release amounts) if releases are below 500 lbs
- § 372.28 — De minimis exemptions: facilities may exclude chemical quantities below 1% concentration (0.1% for carcinogens) in mixtures or trade name products from reporting obligations — reducing compliance burden for facilities that use small concentrations of listed chemicals in commercial products
- § 372.18 — Civil penalties: facilities that fail to report or submit inaccurate reports face civil penalties of up to $25,000 per day per violation; EPA enforces directly against non-reporters; states may also enforce under approved state programs
- TRI chemical list: approximately 800 individual chemicals and chemical categories; Congress added 172 PFAS to the TRI reporting requirement in the FY2020 NDAA (effective for reporting year 2020 reports due July 2021), dramatically expanding PFAS disclosure; EPA updates the list through rulemaking
The TRI database (epa.gov/triexplorer) is one of the most heavily used government datasets — by journalists, investors, community advocates, and researchers — making Part 372 compliance directly visible to corporate stakeholders. The reporting requirement itself creates a transparency-based pollution incentive: facilities consistently reduce TRI releases after they begin reporting because corporate leadership wants to avoid adverse rankings. Recent rulemakings: 85 FR 60448 (September 2020) — 172 PFAS added to TRI; 88 FR 28808 (May 2023) — updated PFAS TRI reporting thresholds.

Pending Legislation

As of April 8, 2026, there is no clearly dominant standalone EPCRA rewrite driving current compliance. The live issues are mostly administrative and regulatory: chemical-list updates, electronic reporting mechanics, PFAS-related TRI expansion, and how states layer more stringent reporting rules on top of the federal floor.

Recent Developments

PFAS reporting continues to expand inside TRI: EPA continues to add PFAS to the TRI list under the FY2020 NDAA framework. For reporting year 2025, EPA states that 205 PFAS are reportable, with forms due by July 1, 2026, and additional PFAS were added for reporting year 2026.
Tier II reporting remains an annual March 1 obligation: EPA's current EPCRA guidance continues to emphasize that section 312 Tier II reports for the prior calendar year are due on or before March 1, and that states may impose additional submission rules or stricter requirements.
Electronic reporting tools remain central to compliance: EPA continues to support electronic submission pathways such as Tier2 Submit and online TRI access tools, which makes the law more operationally usable for facilities, responders, and the public.
40 CFR Part 350 — Trade Secrecy Claims for EPCRA Information: EPCRA allows facilities to claim trade secret status for certain EPCRA information (chemical identity, location, quantities) that would otherwise be publicly reported; a facility seeking trade secrecy protection must substantiate the claim by demonstrating: (a) the information has not been disclosed to the public; (b) no statute or other regulation requires disclosure; (c) disclosure would cause substantial competitive harm; (d) the chemical identity is not readily discoverable through reverse engineering; and (e) the claim is not being made solely to avoid disclosure of hazardous information; even when trade secrecy is granted, EPA may still disclose the specific chemical identity to health professionals treating potentially exposed individuals (§ 11044), local emergency planning committees for emergency response purposes, and state emergency response commissions — with appropriate confidentiality agreements; disclosure to employees or their representatives for safety purposes is also always permitted regardless of trade secret status; EPA reviews trade secrecy substantiations and may determine claims are invalid, in which case the chemical identity becomes publicly available; Part 350 reflects EPCRA's compromise between community right-to-know and legitimate business confidentiality interests
See PFAS Contamination Regulation for the broader PFAS policy. PFAS are now treated more strictly within TRI reporting mechanics: EPA has designated NDAA-added PFAS as chemicals of special concern, which narrows some reporting flexibilities and increases the practical significance of PFAS reporting even beyond ordinary TRI thresholds.
