Members of the U.S. Coast Guard Sector Boston Pollution Prevention Team conduct a drill evaluation known as a Government Initiated Unannounced Exercises (GIUE) at a privately-owned, local fuel storage facility in Boston, Wednesday, May 16, 2018. GIUEs are a regular and important part of the work of Marine Safety Technicians and the Environmental Protection Agency (EPA), working as a partner agency, as they are used to a site's ability to properly respond in the event of an actual discharge of pollutants into sensitive marine environments.
