## Crude supply
- truck: Crude truck unloading at the refinery — The 2024 EPA and Colorado notice of violation says incoming crude oil is received by truck or by pipeline. It describes the Commerce City refinery as a whole and does not split receipts between the West and East plants.

## Product outlets
- truck_rack: Suncor Energy (U.S.A.) Inc. Denver Truck Terminal — Suncor operates a gasoline loading rack called the Denver Truck Terminal, where some of the refinery's finished products are loaded into tanker trucks. The 2024 notice lists the refinery's main products as gasoline, diesel, asphalt, jet fuel and liquefied petroleum gas. The notice does not give the rack's street address or say which plant it sits in, and it does not describe asphalt loading.
- rail: Plant 1 Rail Loading Rack (R101) — Plant 1 has its own rail loading rack, unit R101 in permit 96OPAD120, with a vapor combustion unit regulated under the federal bulk gasoline terminal rule. Colorado's permit review calls it the Plant 1 OMD rack (Plant 1 rail rack). The serving railroad is not named in these documents.
- terminal: Sunoco LP Denver terminal — Sunoco LP's page for its Denver terminal (formerly NuStar) lists the Suncor Refinery as a receipt source, alongside pipeline and ethanol by truck. The page does not say which plant supplies the terminal, by what line, or which products.
