In 2020, the HF Sinclair refineries released approximately 143,134 pounds of ozone precursor chemicals, according to their Environmental Protection Agency (EPA) filings.
HF Sinclair’s record with the Clean Water Act (CWA) is little better. Since 2017, the EPA has fined HF Sinclair $37,900 for illegal wastewater dumping at its Tulsa refineries. As with the CAA violations, these fines have done little to change HF Sinclair’s behavior. According to the EPA’s last monitoring report published in March, the East Holly Refinery is currently operating in violation of the CWA.
