Crude slate

Mid-continent/Patoka-hub crude blend reaching Lemont via the Chicap system, likely combined with Canadian crude typical of Chicago-area refineries.

Crude in & products out

From refinery research; each row links its source.
DirectionModeRoutePoint / originProductsSource
crude in pipeline Enbridge Mainline (Lakehead System)
General sourcing on Chicago-area crude logistics is consistent with the graph's claim but I did not find a source naming Enbridge Mainline specifically for Lemont within budget.
Western Canada crude inferred
crude in pipeline Chicap Pipeline
A trade-press source states plainly that 'the Chicap Pipeline supplies CITGO's Lemont refinery in Lemont, IL.' This is a named crude route NOT currently present as a graph edge for this refinery -- likely a coverage gap.
Patoka/Cushing hub crude blends crude source
products out pipeline Wolverine Pipeline
Wolverine Pipe Line Company's own history describes a dedicated 41-mile, 16-inch pipeline built from the Lemont/Romeoville CITGO refinery to Hammond, IN, and Wolverine's mainline explicitly lists Lemont as one of its refinery origin points. This is a well-documented named products route NOT currently present as a graph edge for this refinery -- a clear coverage gap.
Lemont, IL origin lateral gasoline diesel source
products out marine Chicago Sanitary & Ship Canal
Refinery is authorized to discharge process/wastewater into the canal and is adjacent to it for logistics; a 2025-04 incident confirms an active liquid interface with the canal (see events). Barge product movement specifically was not separately confirmed within budget.

Events

Outages, fires, turnarounds, sales and closures — newest first.
  1. 2025-11-29 sale

    Federal court approved Amber Energy Inc. (Elliott Investment Management affiliate) as acquirer of PDV Holding, Inc. (CITGO's parent), a sale formally approved 2025-12-02 -- a change of ultimate ownership for the Lemont refinery. source

  2. 2025-04 outage

    CITGO reported a fuel line leak on a portable pump resulting in a diesel discharge/sheen into the Chicago Sanitary and Ship Canal at the Lemont refinery. 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.
