The Federal Maritime Commission (FMC) has decided to close its investigation into whether Canadian rules on ballast water management systems were harming U.S. shipping operations in the Great Lakes. Initially sparked by fears of unfair conditions for U.S. ships due to new Canadian regulations, the situation improved enough for the FMC to conclude that short-term issues have been resolved. However, a longer-term investigation remains open to address any potential ongoing concerns. The FMC encourages those affected to continue participating in this ongoing investigation to address any lingering disparities.
Simple Explanation
The Federal Maritime Commission stopped looking into how Canada's rules for water in ships might be causing problems for U.S. ships in the Great Lakes because things have gotten better for now, but they're still checking to make sure the problems don't come back later.
