One of the first steps is that the federal government needs to clarify the definition of a mooring buoy as a minor work. There needs to be a clearer definition of “abandoned” and a clearer definition of “dilapidated”. You can do this by regulation.
Once that's been clarified, you could go to an organization like the Coast Guard. It would able to very easily set up a list of criteria as to what is hazardous. I'm sure it could come up with three, four or five top criteria pretty quickly.
