Berkshire Hathaway Inc

Berkshire Hathaway Inc appears in the EPA Toxics Release Inventory as the parent or reported corporate owner of 205 individual facilities filing Form R disclosures under EPCRA Section 313. Operations span 37 states, and across all sites the company has disclosed a cumulative release total of 88.8M lbs.

The aggregated chemical footprint covers 991 distinct substances, of which 34 carry a carcinogen classification in the EPA Toxics Release Inventory. The heaviest-reporting state by release volume is Wyoming (4 facilities, 21.2M lbs), followed by Indiana at 20.7M lbs. The single largest facility disclosure is CERRO WIRE LLC in IN at 20.6M lbs.

Parent-company aggregation uses the company name as reported by each facility on its annual TRI filing; mergers, divestitures, or reporting variations across subsidiaries can produce inconsistent attribution year over year. All values are self-reported estimates under federal community right-to-know law and are not weighted by toxicity. Inclusion in the TRI does not establish a health risk to the public, it documents the regulatory disclosure record.
