Crude slate

The refinery's general manager said in 2016 that one-fourth of its crude comes from the local area. The plant also runs locally gathered Utica shale condensate through its on-site splitter.

Crude in & products out

Direction	Mode	Route	Point / origin	Products	Source
crude in	pipeline	Cornerstone Pipeline Marathon commissioned the 42-mile, 16-inch Cornerstone Pipeline on 29 September 2016. It carries condensate from the MarkWest stabilizer at Cadiz to Marathon's tank farm at East Sparta, about eight miles south of Canton. The condensate feeds the refinery's splitter.	Cadiz / Harrison County, OH (Utica shale, via MarkWest/MPLX gathering)	crude	source
crude in	pipeline	unnamed interstate crude pipeline system (Marathon/MPLX network) Marathon states the refinery receives crude 'through an interstate pipeline system from other regions, including the Gulf Coast and Canada'; no specific named line other than Cornerstone was identified for the heavier crude portion of the slate.	Gulf Coast and Canada	crude	source

crude in	pipeline	Ohio River Pipe Line The Ohio River Pipe Line tariff (FERC No. 76.35.0, effective 1 July 2026) allows reverse flow from East Sparta to Canton at a shipper's request, with a minimum batch of 10,000 barrels. Normal operation is Canton to East Sparta. The tariff does not say what is shipped into the refinery this way.	East Sparta, OH	crude	source
products out	pipeline	Ohio River Pipe Line The Ohio River Pipe Line LLC tariff (FERC No. 76.35.0, effective 1 July 2026) lists Canton, Ohio as an origin with a rate of 19.19 cents per barrel to East Sparta, Ohio. Normal operation is Canton to East Sparta. The tariff is published on the MPLX website.	Canton refinery (Canton, Ohio, Stark County), to East Sparta, OH	gasoline distillate	source
products out	truck rack	Marathon Refinery Canton truck rack (IRS T-34-OH-3140 and T-34-OH-3177) The IRS terminal list holds two records at the refinery's address, 2408 Gambrinus: Marathon Refinery Canton (T-34-OH-3140) and Canton Refining Logistics (T-34-OH-3177). Marathon says product distribution is by pipeline, transport truck and rail. Whether the two records are two racks or one is not established.

products out	rail	Canton refinery rail Marathon says product distribution includes rail but does not name the products. The Ohio EPA fact sheet for the plant's water permit lists an Asphalt Plant Rail Spur. The serving railroad is not named.	Canton refinery		source
products out	pipeline	Marathon Pipe Line (unspecified products line) Marathon's own refinery page states 'Product distribution occurs through pipeline, transport truck and rail' but does not name the specific outbound products pipeline; MPLX (Marathon-affiliated) is the most likely operator of any such line given it also owns the inbound Cornerstone crude/condensate line.

Events

2025-07-15 turnaround
MNI (July 16, 2025): Marathon's 100k b/d Canton refinery began a full-plant turnaround. The 26k b/d FCC, 31k b/d naphtha hydrotreater and 24k b/d ULSD hydrotreater were shut July 15. Work was staggered over about 60 days into early/mid-September and covered two crude units, the catalytic reformer and hydrotreaters. 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.
