## Crude supply
- marine: Louisiana Offshore Oil Port (LOOP) — Reference site states crude is 'supplied via the Louisiana Offshore Oil Port (LOOP)', primarily heavy sour crude oils.
- pipeline: Capline Pipeline — Capline reversed to full southbound service Jan 1, 2022; the pipeline operator (Marathon Pipe Line, a Marathon affiliate) explicitly names Garyville as a served destination for the reversed, southbound Canadian/Bakken crude.
- pipeline: LOCAP Pipeline — Consistent with the LOOP crude-supply finding above; LOCAP is the documented onward pipeline link from LOOP's onshore terminal to Mississippi River corridor refineries, though this specific refinery tie-in was not separately re-confirmed this session beyond the general LOOP reference.

## Product outlets
- pipeline: Bengal Oil Products Pipeline / Colonial Pipeline — Reference site states the refinery 'is connected to the Bengal Oil Products Pipeline' and 'products can be shipped via the Colonial Oil Products Pipeline' -- consistent with the Bengal JV (Colonial/Shell Midstream) linking southern Louisiana refineries to Colonial's Baton Rouge origin.
- pipeline: Plantation Pipeline — Plantation Pipeline's documented origin point is Baton Rouge specifically (not Garyville); no source reviewed confirms a direct Garyville injection point onto Plantation. Treat as unconfirmed.
- pipeline: Centennial Pipeline — Centennial's Louisiana segment runs Beaumont, TX to Longville, LA (western/central LA) and north to Illinois -- it does not pass through or originate at Garyville (St. John the Baptist Parish, on the river between New Orleans and Baton Rouge). No source ties Garyville product to Centennial.
- truck_rack: Garyville MPC Asphalt Terminal — Company-named on-site asphalt terminal -- direct company asset.
- marine: Marathon Petroleum Company LLC - Terminal Transport and Marine Division — Company-named marine/barge division -- direct company asset, consistent with the refinery's Mississippi River frontage.
