As-of Data

EPA Facility & Program Records — State Slices

Daily as-of snapshots of the EPA Envirofacts facility-program registry for four small states (DC, RI, VT, DE). Stable composite keys, full source bytes, and explicit coverage disclosure.

Coverage below is reported per source endpoint. A gap badge means that day's coverage was incomplete — we disclose it rather than backfill with older values. Original bytes are never discarded.

          How to cite

          Use source_url + record_id + as_of_date + sha256. The dataset hash in the manifest covers the exact JSONL event set for that day, so a recipient can recompute it. See Docs.
