US federal chemical regulatory reporting thresholds by program (CERCLA, EPCRA, CAA)
Canonical, always-current version: https://referencesource.org/chemical-regulatory-reporting-thresholds/ Machine-readable: https://referencesource.org/chemical-regulatory-reporting-thresholds/data.json — this mirror is a point-in-time copy.
- Last verified: 2026-08-05
- Stale after: 2027-08-05 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
- Records: 1336
Cross-program comparison of federal regulatory thresholds for hazardous chemicals. Each record is one chemical with the thresholds that trigger obligations under different federal programs: CERCLA reportable quantity (release reporting to NRC), EPCRA Section 302 threshold planning quantity (emergency planning), EPCRA Section 313 reporting threshold (TRI), and CAA Section 112(r) threshold quantity (risk management plan). The product is the cross-reference: for benzene, CERCLA RQ is 10 lb, EPCRA TPQ does not apply (not an EHS), but Section 313 threshold is 10 lb — three different programs, three different questions, answered from one page. Answers 'what are all my reporting obligations for [chemical]', 'is [chemical] an extremely hazardous substance under EPCRA', and 'what is the reportable quantity for [chemical]'.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
Licence position
US government work — public domain. All values from 40 CFR 302.4 and 40 CFR 355, published by EPA in the eCFR.
Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
