Seaway Pipeline Co. shut down part of its pipeline system following a leak of crude oil in Cushing, Okla., on Oct. 24, said Enterprise Products Partners LP, which operates the pipeline in a venture with Canada's Enbridge Inc.

The 500-mile, 30-inch pipeline system connects the crude storage hub of Cushing to the Freeport, Texas, area, and a terminal and distribution crude oil network that serves all the refineries in the Greater Houston area.

Enterprise said on Oct. 24 that there was no threat to the public and no evacuations were ordered following the spill, located near the intersection of Lynnwood Avenue and Texaco Road in Cushing.

The company was working with emergency responders and law enforcement to address the situation.

A company spokesman said the spill occurred on the Seaway legacy line. He could not immediately confirm if the incident also resulted in the shutdown of the Seaway Twin Pipeline, and did not provide an estimate of the volume of crude spilled.

Energy intelligence firm Genscape also reported the shutdown of its 450,000 barrels per day (Mbbl/d) Seaway Twin Pipeline, which expands the existing Seaway Pipeline.

The Seaway Pipeline system has a total capacity of about 850 Mbbl/d, according to the company's website.

The Seaway spill comes on the heels of a Sunoco Logistics Partners LP pipeline spill on Oct. 21, which released about 1,300 bbl, or 55,000 gallons, in the vicinity of the Susquehanna River in Lycoming County, Pa.

The prompt crude spread, which often correlates to the supply-demand balance in Cushing, traded as wide as 69 cents on Oct. 24, the biggest discount in nearly two months.
