"caused the largest inland oil spill in Midwest history" and reported the cost of the cleanup at $36.7 million (US) as of November 14, 2011. PHMSA raised concerns in a Corrective Action Order (CAO) about numerous anomalies that had been detected on this pipeline by internal line inspection tools, yet Enbridge had failed to check a number of those anomalies in the field. The Michigan spill affected more than of waterways and wetlands and about 320 people reported symptoms from crude oil exposure. The National Transportation Safety Board said at $800 million, it was the costliest onshore spill cleanup in U.S. history. The NTSB found Enbridge knew of a defect in the pipeline five years before it burst. In June 2013, a Kalamazoo man lodged himself into an Enbridge pipeline in Marshall, MI to protest Enbridge's lack of accountability for the 2010 spill and to encourage landowners along Enbridge's Line 6B expansion to offer increased resistance to construction in 2013. In 2014, Enbridge completed cleanup of the river per the EPA's order. On September 9, 2010, a broken water line caused a rupture on Enbridge's Line 6A pipeline near Romeoville, Illinois, released an estimate of oil into the surrounding area. On June 22, 2013, Enbridge subsidiary Athabasca pipelines reported a pipeline leak of approximately 750 barrels of light synthetic crude oil from Line 37 near Enbridge's Cheecham, Alberta, terminal about southeast of Fort McMurray. The 17-kilometre-long, 12-inch diameter pipe was constructed in 2006 and links the Long Lake oilsands upgrader to the Cheetham terminal as part of Enbridge's Athabasca system. Unusually heavy rainfall in the region, also responsible for the 2013 Alberta floods, may have caused "ground movement on the right-of way that may have impacted the pipeline." Enbridge's Athabasca (Line 19) shares a portion of right of way with Line 37 and Enbridge's Wood Buffalo/Waupisoo (Line 75/18) which also shares a portion of right of way with Line 37, a major part of the network that serves Alberta's oilsands, were closed down as a precautionary measure. Operations between Hardisty and Cheecham were restored on June 23 when Enbridge's Athabasca pipeline (Line 19) was restored to service. On July 1, 2013, WWMT News in Michigan reported that the Michigan Department of Environmental Quality had issued a citation against Enbridge for contamination of North Ore Creek by an Enbridge pipeline maintenance activity.
