Crude slate
Mixed heavy, high-sulfur crude: California San Joaquin Valley/LA Basin heavy crude (pipeline) plus Alaska North Slope, South American and West African imports (marine via Long Beach).
Crude in & products out
| Direction | Mode | Route | Point / origin | Products | Source |
|---|---|---|---|---|---|
| crude in | pipeline | Unnamed in-state pipeline(s) Marathon's own site states the refinery 'processes heavy crude from California's San Joaquin Valley and Los Angeles Basin' delivered domestically; an older description specifically notes domestic crude is received by pipeline from California. |
California San Joaquin Valley and Los Angeles Basin heavy crude | crude | source |
| crude in | marine | Third-party marine terminal, Port of Long Beach Crude oil (foreign and additional domestic) is received by tanker through a third-party terminal in the Port of Long Beach and piped to the refinery; directly confirms the graph's LA/Long Beach Harbor marine-terminal inbound edge. |
Alaska North Slope, South America, West Africa, and other international crude | crude | source |
| products out | pipeline | Kinder Morgan SFPP (West Line) SFPP's West Line explicitly moves refined products out of the Los Angeles Basin (where Carson is located) toward Colton/Imperial, CA and Phoenix, AZ; Marathon's own materials say the refinery 'ships products via its connections to several product distribution pipelines and terminals' without naming them. |
Los Angeles Basin | gasoline distillate | source |
| products out | rack terminal | SFPP, L.P. - Watson Station 'Watson' is the name of the Carson refinery site itself (home to the refinery's Watson Cogeneration Plant, the largest cogen facility in California) -- a Kinder Morgan SFPP Watson Station rack terminal at this location is consistent with a refinery-direct product offtake. |

expansion
CEQA notice filed for the 'Marathon Los Angeles Refinery Modernization Projects,' aimed at replacing end-of-life equipment, adding asphalt-binder production capability, and enabling flexible shifts between transportation-fuel and octane-blending-component yields. source
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.
