## Crude supply
- marine: Sabine-Neches Waterway — Deepwater channel access shared by Beaumont/Port Arthur refineries.
- pipeline: Nederland to Port Arthur crude pipeline — RBN Energy states Nederland terminal has direct pipeline connections to the Valero and Total Port Arthur refineries in addition to Motiva and ExxonMobil Beaumont.
- pipeline: Keystone Pipeline — Keystone/Marketlink barrels reach the Nederland hub; the Port Neches Link spur was purpose-built for Motiva specifically, so a direct Keystone-to-Valero-PA connection is plausible via Nederland terminal blending/redelivery but not separately confirmed by a Valero-specific source.

## Product outlets
- truck_rack: Valero LP refinery rack — Refinery-direct truck rack; self-evident for an operating Valero refinery of this scale.
