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.
