Texas Attorney General Ken Paxton is hauling a Freeport chemical plant into court, accusing operator Blue Cube Operations LLC of repeatedly releasing chlorine and other hazardous chemicals that put nearby residents and workers at risk. In a new complaint, state investigators say they documented at least 11 unauthorized emissions events between 2022 and 2025, including a May 2025 chlorine leak serious enough to trigger shelter-in-place orders in the surrounding area.
The State filed the case in Travis County on April 9 and is asking for civil penalties, attorney fees and a temporary injunction while regulators sort through the findings, according to the State of Texas. The complaint, filed on behalf of the Texas Commission on Environmental Quality, leans heavily on past TCEQ investigations and seeks both monetary and non-monetary remedies.
Regulators Say Plant Kept Busting Emissions Limits
State enforcement files show the Freeport site has drawn multiple investigations and enforcement actions in recent years. In one example cited by the State, TCEQ records describe a July 2022 event that released about 6,741 pounds of ethylene dichloride, one of several incidents regulators flagged in their files, according to the Texas Commission on Environmental Quality.
May 2025 Chlorine Leak Sickened Workers, Spooked Towns
The lawsuit says Blue Cube emitted 8,011 pounds of chlorine from a leak on May 20, 2025, and that four people were treated for injuries, according to the State of Texas. Local officials and residents later told the Houston Chronicle that public warnings lagged, and many people first learned about the hazard through social media and neighbor-to-neighbor word of mouth rather than official alerts.
What Paxton Wants The Judge To Do
Paxton's office says the State is seeking civil penalties along with court-ordered corrective measures that would force the company to bring in independent auditors, produce Auditor's Reports and follow a schedule of corrective actions, according to coverage of the attorney general’s announcement. The suit is framed as an effort to protect public health while pushing Blue Cube to comply with the Texas Clean Air Act, as reported by Fox 26 Houston.
Plant Background And Prior Enforcement History
Blue Cube operates chlorine, vinyl and related units at the Freeport complex, and publicly available company filings place those operations within Olin Corporation's portfolio. The TCEQ record shows prior agreed orders and a 2024 findings order that assessed administrative penalties against the Freeport site, underscoring a pattern of permit deviations and missed monitoring requirements documented by the agency.
What Happens Next For Freeport Residents
The case is active in Travis County, and the State's request for injunctive relief could lead to binding operational changes at the Freeport plant if a judge signs off. Blue Cube did not provide a public statement to media outlets at the time of reporting, according to Fox 26 Houston. Regulators and local emergency planners say they will keep reviewing alert systems and response procedures while the litigation plays out.
