Members of the U.S. Coast Guard Sector Boston Pollution Prevention Team oversee the deployment of a boom around oil transfer equipment during a drill evaluation known as a Government Initiated Unannounced Exercises (GIUE) at a privately-owned, local fuel storage facility, Wednesday, May 16, 2018. GIUEs are conducted by Marine Safety Technicians and the Environmental Protection Agency (EPA), working as a partner agency, to ensure that staff at privately owned facilities are prepared and equipped to respond in the event of an actual discharge of pollutants.
