| Direction | Mode | Route | Point / origin | Products | Source |
|---|---|---|---|---|---|
| crude in | pipeline | Mobil Pipe Line Mokena-to-Joliet crude pipeline Final leg into the refinery. A 2014 open season notice for the JBBR Pipeline names Mobil Pipe Line Company's Mokena-to-Joliet crude pipeline as the line giving shippers direct access to the Joliet refinery. ExxonMobil's 2026 fact sheet lists a terminal or tank farm at Mokena among its area facilities. |

| crude in | pipeline | Enbridge Mainline (Lakehead System) Enbridge's February 2021 index of Lakehead tariffs lists Mokena, Illinois as a crude petroleum destination. Crude delivered at Mokena reaches the refinery over the Mobil Pipe Line Mokena-to-Joliet line. ExxonMobil says the plant is located to receive and process Canadian crude oil delivered by pipeline; no Enbridge tariff names the refinery itself. |

| crude in | rail | Joliet Bulk, Barge & Rail (JBBR) crude-by-rail terminal and JBBR Pipeline Crude is unloaded from rail at the JBBR terminal and moves on the JBBR Pipeline to the Mobil Pipe Line Mokena-to-Joliet crude line. A 2014 notice described the terminal as built, owned and operated by Joliet Bulk, Barge & Rail LLC; Argus reported in 2015 that the site is owned by CenterPoint Properties and serves only ExxonMobil. Sources date from 2014 and 2015. |

| products out | pipeline | Wolverine Pipeline Two Wolverine lines leave the plant: a 22-mile, 16-inch line to Lockport, Illinois (1972), where Wolverine lists an ExxonMobil terminal, and a 49-mile, 18-inch line to Hammond, Indiana (1976). Wolverine's FERC tariff 170.15.0, effective 2026-07-01, files rates from Joliet to Lemont-Lockport and to Hammond, with volume incentive rates for RBOB and on-road ultra low sulfur diesel from Joliet to Hammond. Wolverine's own pages name the Joliet origin as the ExxonMobil Refinery. |

-
2025-05-20
outage
Operational issue left most units offline; refinery ramped a key unit back to full capacity by late May 2025. source
-
2024-07-15
outage
Emergency shutdown after severe weather damaged ComEd primary/secondary power lines; refinery offline roughly three weeks; EPA issued an emergency fuel-supply waiver in response to the Midwest gasoline impact. 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.
