On January 26, 2022, an explosion involving an empty ethylene dichloride tank at Westlake's Sulphur, Louisiana, plant injured six workers, with the incident attributed to overpressurization during cleaning operations; investigations highlighted risks from the flammable carcinogen, prompting OSHA scrutiny amid the company's history of similar events.[104][105]
A fatal incident occurred on May 11, 2025, at Westlake's Proctor, West Virginia, plant, where 44-year-old maintenance worker Steven E. Chambers died after being struck by a high-pressure water line rupture during hydroblasting operations; the Marshall County Sheriff's Office reported the explosion's force caused the worker to fall approximately 20 feet, with OSHA initiating an investigation into potential lockout/tagout and pressure testing failures.[106][107]
Westlake facilities have faced repeated OSHA citations for workplace safety violations, including process safety management deficiencies linked to fires and releases, with penalties totaling over $50,000 in individual cases since 2018 and a broader pattern of incidents at Louisiana sites involving chemical spills and explosions.[101][108][109]
Environmental Violations and Fines
Westlake Corporation, through its subsidiaries and facilities, has faced multiple environmental enforcement actions primarily related to air pollution violations under the Clean Air Act, including excess emissions from flares, startups, shutdowns, and malfunctions, as well as unauthorized releases of hazardous substances like vinyl chloride.[101] Aggregate penalties for environmental violations exceed $117 million across 46 records, with air pollution offenses accounting for over $2.3 million in 19 instances, according to data compiled from federal and state agencies.[101]
In October 2024, the U.S. Environmental Protection Agency (EPA) settled with Westlake Chemicals and Vinyls LLC at its Lake Charles, Louisiana facility for $825,000 in civil penalties, addressing violations of startup, shutdown, and malfunction reporting requirements that led to unpermitted emissions of volatile organic compounds and hazardous air pollutants.[110] The settlement required enhanced compliance measures, including improved monitoring and reporting systems.[111]
A June 2022 settlement with EPA and the U.S. Department of Justice involved Westlake subsidiaries at facilities in Geismar, Louisiana; Plaquemine, Louisiana; and Longview, Texas, imposing a $1 million civil penalty for improper flaring practices that released thousands of tons of pollutants, including benzene and ethylene.[112] The agreement mandated installation of flare gas recovery systems and operational controls to reduce future emissions by an estimated 1,200 tons annually.[6]
Earlier actions include a 2022 consent decree with EPA, Kentucky, and Louisiana departments against Westlake Chemical OpCo and affiliates, resolving Clean Air Act violations at multiple sites with penalties and pollution controls.[113] In Kentucky's Calvert City facility, operated by Westlake Vinyls, regulators documented at least six instances of unauthorized vinyl chloride emissions since 2010, a known carcinogen, leading to fines and ongoing litigation by local residents alleging health impacts.[114] A 2010 decree with Kentucky required a $100,000 penalty for similar air quality breaches.[115] In 1999, Westlake's Louisiana petrochemical plant faced proposed federal penalties of $305,830 for wastewater and air violations, plus state fines.[116]
Date Facility/Location Violation Type Penalty Amount Agency
Oct 2024 Lake Charles, LA Startup/shutdown/malfunction emissions $825,000 EPA[110]
Jun 2022 Geismar/Placquemine, LA; Longview, TX Flare emissions (benzene, ethylene) $1,000,000 EPA/DOJ[112]
2022 Multiple (OpCo sites) Clean Air Act non-compliance Undisclosed (decree terms) EPA/KY/LA[113]
2010+ Calvert City, KY Vinyl chloride releases (6+ incidents) Multiple fines State/EPA[114]
1999 Louisiana petrochemical Wastewater/air discharges $305,830 (federal proposed) EPA/LDEQ[116]
These enforcement actions reflect recurring issues in chemical manufacturing operations, where flaring and process upsets have been common vectors for non-compliance, though Westlake has implemented remedial technologies in settlements to mitigate ongoing risks.[101]
Company Responses and Industry Context
In response to EPA allegations of improper flare operations leading to excess emissions at facilities in Geismar, Louisiana; Lake Charles, Louisiana; and Calvert City, Kentucky, Westlake subsidiaries agreed in June 2022 to install advanced air pollution control and monitoring technologies, reducing thousands of tons of volatile organic compounds, hazardous air pollutants, and greenhouse gases annually, while paying a $1 million civil penalty.[112] This settlement addressed violations under the Clean Air Act's flare management standards, which require at least 95% destruction efficiency for piped contaminants.[114] Similarly, following inspections revealing deficiencies in startup, shutdown, and malfunction event reporting at its Westlake, Louisiana plant, the company settled in October 2024 for an $825,000 penalty and committed to enhanced compliance measures.[110] Westlake has also faced subsurface trespass claims, culminating in a $76 million judgment payment in August 2025 after appeals, related to unauthorized migration of injected fluids affecting adjacent properties.[117]
Regarding safety incidents, such as the January 2022 ethylene dichloride explosion at its Sulphur, Louisiana facility that injured workers, Westlake cooperated with OSHA investigations, resulting in $139,427 in penalties for process safety management violations during maintenance activities.[102] [118] The company maintains comprehensive emergency response protocols, including precautions against accidents and commitments to healthful workplaces, as outlined in its internal health and safety programs updated as of February 2025.[119] In its 2023 sustainability reporting, Westlake emphasized ongoing investments in environmental compliance and risk management, aligning operations with frameworks like the UN Global Compact to mitigate impacts from petrochemical production.[120]
Within the broader chemical industry, particularly in high-density petrochemical hubs like Louisiana's "Petrochemical Corridor," facilities routinely encounter regulatory scrutiny for emissions and safety under the Clean Air Act, Risk Management Program rules, and OSHA standards, with peers such as Sasol Chemicals facing comparable multimillion-dollar settlements for fire-related violations and process safety lapses.[121] [122] These challenges stem from handling inherently hazardous feedstocks and extreme weather vulnerabilities, as seen in hurricane-induced releases across regional plants, yet enforcement via fines and mandated upgrades—totaling over $110 million in Westlake's 2022 air pollution commitments—drives incremental improvements in flare efficiency and leak detection, though critics note persistent exceedances in areas like vinyl chloride emissions relative to permitted limits.[7] [114] Industry-wide data from EPA enforcement actions indicate that flaring inefficiencies and malfunction events are common, affecting multiple operators and prompting calls for stricter federal oversight, balanced against the sector's role in producing essential materials like PVC and ethylene derivatives.[112]
