Officials say firefighters who responded to February’s fiery train derailment in Ohio struggled to immediately identify the hazardous chemicals the train was hauling due to poor communication from the railroad.

Federal regulators want first responders to a train derailment to know exactly what they are dealing with even before they reach the scene.

Michigan Governor Gretchen Whitmer demanded Friday that Enbridge Energy provide proof that the damage to one of its dual oil pipelines under the Straits of Mackinac will not pose a threat to the area. Whitmer said the damage and how it occurred calls into question the viability of the pipeline. Thats why I am requesting Enbridge turn over to the State of Michigan all relevant information about this most recent damage and provide affirmative evidence that establishes the integrity of the pipeline, Whitmer said in a statement. Duffy clarified that the problem does not affect the pipeline, which he said was shut down as a precaution. The EPA determined that Enbridge neglected to properly evaluate thousands of shallow dents on its Lakehead Pipeline System, which runs across northern Minnesota and northwestern Wisconsin.
