# World Oil Refining (formerly Lunday-Thagard) South Gate Refinery

World Oil Refining (formerly Lunday-Thagard) South Gate Refinery, South Gate, CA. 8,500 bpd crude capacity (EIA-820). Crude supply, outlets, events.

- Location: South Gate, CA
- Status: active
- Crude capacity: 8,500 bpd (EIA-820)
- Operator: Lunday-Thagard Co. dba World Oil Refining
- Parent: World Oil Corp

## Crude supply
- marine: Ribost Marine Terminal (affiliate) — Ribost Marine Terminal LLC is a ~500,000-bbl marine storage and transfer terminal in Long Beach Harbor operated as a World Oil Corp affiliate; it is the logical marine receipt point for crude/feedstock destined for the South Gate plant, but no source explicitly states the refinery-to-terminal pipeline connection, so this is an inference from corporate-family structure.
- truck: Pan Pacific Petroleum Co. (affiliate trucking) — Affiliate trucking company hauling from Bakersfield and South Gate; likely used for feedstock and/or recycled-oil supply given the plant processes heavy crude and recycled feedstocks. Inference, not directly documented as a refinery inbound route.

## Product outlets
- rail: D/K Environmental (affiliate railcar facility) — Affiliate railcar loading/transfer facility in Vernon; plausible outbound route for asphalt/byproducts but not directly confirmed as a South Gate refinery product route.
- truck_rack: Refinery truck rack (South Gate) — Asphalt and specialty-products refineries of this size and configuration typically distribute almost entirely by truck rack; no explicit truck-rack citation was found beyond general product listings.
