Every facility that has filed toxic-release reports under EPCRA Section 313 since 1987 — 64,989 sites across manufacturing, mining, electric utilities, federal facilities, and chemical wholesalers. The master list of legal toxic-releasers in the United States. Pairs with epa_facilities (ECHO master), epa_enforcement_cases (ICIS-FE&C 134k cases), to identify which facilities both report AND get cited. Per-facility canonical pages link to the EPA TRI Report search where year-by-year chemical release amounts can be retrieved.
