Crude slate

Sweet and sour crude oils received from Colorado, Montana, North Dakota, Wyoming and Canada, by truck or by pipeline, according to the 2024 EPA and Colorado notice of violation. The statement covers the whole Commerce City refinery, not the West plant alone.

Crude in & products out

Direction	Mode	Route	Point / origin	Products	Source
crude in	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.	Colorado, Montana, North Dakota, Wyoming and Canada (source areas given for the refinery as a whole)	crude	source
products out	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.	Commerce City, CO	gasoline distillate asphalt	source
products out	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.	Plant 1, Commerce City, CO	gasoline	source
products out	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.	3601 E 56th Street, Commerce City, CO		source

Ownership

This record is the West Plant, which is Plant 1 and Plant 3 under one Colorado operating permit (96OPAD120) at 5801 Brighton Boulevard. Plant 1 is the former Conoco refinery on the west side of Brighton Boulevard. Plant 3 is the asphalt unit of the former Conoco facility and lies east of Plant 2, on the east side of Brighton Boulevard. Plant 2 is the East Plant and has its own record and permit. EPA treats the East and West plants as a single major source, and its 2024 notice says the three plants are connected so that materials can be routed from one plant to another. Per Wikipedia, Suncor acquired the original Commerce City refinery in 2003 from ConocoPhillips and a second, adjacent facility in 2005 from Valero Energy.

Rates are pipeline line-haul transcribed from published FERC tariffs; every figure cites its tariff and item. Cost to serve (netback) adds origin spot price and destination fees. "Confirmed" links match a tariff delivery point to the facility; "same city" means the point is in the facility's city — plausible, not proof; "per research" means the facility's research profile names the pipeline as an outlet.
