Great Lakes Seaway Ballast Water Working Group releases 2016 ballast water management report

The Coast Guard announced the release of the Great Lakes Seaway Ballast Water Working Group’s (BWWG) 2016 Summary of Great Lakes Seaway Ballast Water Management activities.

The Great Lakes Seaway Ballast Water Working Group is a binational collection of representatives from the U.S. Coast Guard, the U.S. Saint Lawrence Seaway Development Corporation, Transport Canada – Marine Safety & Security and the Canadian St. Lawrence Seaway Management Corporation.

The group’s mandate is to develop, enhance and coordinate binational compliance and enforcement efforts to reduce the introduction of aquatic invasive species via ballast water and residuals.

In 2016, 100 percent of vessels bound for the Great Lakes Seaway from outside the Exclusive Economic Zone received a ballast water management exam. In total, the BWWG assessed all 8,488 ballast tanks during the 466 vessel transits in the 2016 navigation season.

This is the seventh consecutive year that BWWG agencies ensured the examination of 100 percent of ballast tanks entering the Great Lakes via the St. Lawrence Seaway, and the group anticipates continued high ship-compliance rates for the 2016 navigation season.
