EPA NESHAP Source Category Applicability Crosswalk

Canonical, always-current version: https://referencesource.org/neshap-source-category-crosswalk/ Machine-readable: https://referencesource.org/neshap-source-category-crosswalk/data.json — this mirror is a point-in-time copy.

• —Last verified: 2026-08-15
• —Stale after: 2026-12-13 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
• —Records: 125

Maps each EPA NESHAP source category to its 40 CFR subpart, whether it applies to major or area sources, the original final rule date, most recent amendment, and residual risk/technology review status.

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

unknown

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.
