Yes, I know a bit about it. It went through the U.S. legislature and was voted on and passed. Because of the problem that was identified, primarily with sea lions, I believe, they allowed for the killing of sea lions in that area.
This is true of the U.S. east coast as well. There is a lot of information available on the grey seals. Some of the commentary down there is that, well, if you take care of the population, it will only be replaced by Canadian grey seals, which are in the area.
