I work at Motiva refinery — do I need ACA health insurance?

Direct Motiva employees typically have employer-sponsored coverage. Contract workers — turnaround crews, maintenance contractors, scaffolding and insulation workers — often do not have employer benefits and may qualify for ACA marketplace subsidies based on household income. Losing a contract triggers a 60-day Special Enrollment Period.

Can I get Louisiana Medicaid if I work in Lake Charles but live in Port Arthur?

No. ACA and Medicaid enrollment are based on your state of residence. If you live in Port Arthur, you use the Texas marketplace and follow Texas Medicaid rules — which have NOT expanded Medicaid. Louisiana's expanded Medicaid is only available to Louisiana residents. This cross-state difference is one of the sharpest along the Gulf Coast.

Port Arthur is an industrial city on the Texas Gulf Coast best known for one thing: the Motiva Enterprises refinery — the largest oil refinery in North America, with a capacity of over 600,000 barrels per day. The city's approximately 56,000 residents live in one of the most diverse small cities in the United States, with significant African American, Vietnamese, and Hispanic populations. Port Arthur's economy revolves almost entirely around the petrochemical industry, and its health insurance landscape is defined by the gap between direct refinery employees with benefits and the broader community that depends on the ACA marketplace.

Port Arthur also illustrates one of the sharpest state-line health insurance contrasts on the Gulf Coast. Lake Charles, Louisiana — just 60 miles east — sits in a state that expanded Medicaid in 2016. Port Arthur sits in Texas, which has not expanded Medicaid. A low-income refinery contractor living in Port Arthur falls into a coverage gap that the same person living in Lake Charles would not face.

Motiva Refinery and the Contract Workforce

The Motiva refinery dominates Port Arthur's economy. Valero and Total Energies also operate significant refining capacity in the area. The health insurance divide in Port Arthur is stark:

Refinery Employment and Insurance Direct employees of Motiva, Valero, and Total typically have comprehensive employer-sponsored health insurance. The contractor workforce — turnaround crews, maintenance workers, scaffolders, insulation workers, sandblasters, and crane operators — often lacks employer coverage. During major turnarounds, the contractor population in Port Arthur can swell by thousands. These workers are the core of the local ACA marketplace population and may qualify for substantial premium tax credits.

The Texas-Louisiana Border

Texas Coverage Gap vs. Louisiana Medicaid Port Arthur is 60 miles from Lake Charles, Louisiana. Louisiana expanded Medicaid — residents below 138% FPL qualify for Medicaid coverage. Texas has NOT expanded Medicaid — Port Arthur residents at the same income fall into a coverage gap with no subsidized option. A refinery contractor earning $14,000/year in Port Arthur has no Medicaid eligibility and no ACA subsidy. The same worker living in Lake Charles would qualify for Louisiana Medicaid. This is one of the starkest health insurance disparities along any state border in the US.
