|---|---|---|---|---|
| Buckeye Pipeline | 25 | 49 | 22.63 | 180.74 |

## Crude supply
- pipeline: Enbridge Line 5 (via Marysville pumping station / Sunoco pipeline to Toledo area) — Line 5 carries light crude oil, light synthetic crude, and NGLs; Wikipedia's Line 5 article explicitly names 'Marathon Detroit' (with BP Husky) as a refinery receiving volumes offloaded at Marysville. Line 5 does not carry heavy crude.
- pipeline: Enbridge Line 78 and/or Mid-Valley Pipeline — Detroit refinery is configured to run 80,000 bpd of heavy crude; since Line 5 does not deliver heavy crude, a National Wildlife Federation-commissioned study (London Economics International) states Marathon sources this heavy crude from Enbridge Line 78 and/or the Mid-Valley pipeline.

## Product outlets
- marine: Detroit River / Rouge River barge dock — Refinery's riverfront location in the Detroit/Rouge River industrial corridor is well documented, consistent with barge dock access, though a dedicated source naming an active product barge dock was not found this session.
- pipeline: Wolverine Pipe Line — Wolverine Pipeline is a well-known refined-products system serving Michigan markets from Midwest refineries; plausible as an outbound route from Marathon Detroit, but no source found this session specifically naming Marathon Detroit as an injection point (Wolverine more commonly cited as delivering product INTO Michigan from refineries further west/south, e.g. Whiting).
- pipeline: Buckeye Michigan/Ohio products system — Not independently confirmed this session; plausible given the well-documented Buckeye Terminals cluster (Taylor, River Rouge, Woodhaven) in the Detroit metro area.

## Recent events
- 2025 — Hydrogen production facility electrical installation project at the refinery (1300 South Fort Street, Detroit) performed by Motor City Electric, indicating continued capital investment; scope/impact on supply not detailed.
