To require the Secretary of Transportation to conduct a study on the economic and environmental risks to the Great Lakes of spills or leaks of oil, and for other purposes.

Preserve Our Lakes and Keep Our Environment Safe Act This bill directs the Department of Transportation (DOT) to conduct a study to determine the economic and environmental risks of oil or hazardous liquids spills or leaks in the Straits of Mackinac that a failure of onshore, underwater pipeline facilities within the straits would pose to the Great Lakes. In addition, DOT must evaluate the condition and structural integrity of the facilities. DOT shall terminate operations of a facility upon a determination, based on such studies, that risk of hazard to life, property, or the environment warrants termination.
