Westlake Corp appears in the EPA Toxics Release Inventory as the parent or reported corporate owner of 42 individual facilities filing Form R disclosures under EPCRA Section 313. Operations span 20 states, and across all sites the company has disclosed a cumulative release total of 16.8M lbs.
The aggregated chemical footprint covers 312 distinct substances, of which 38 carry a carcinogen classification in the EPA Toxics Release Inventory.

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.
