P-I says Cantwell perpetuates the EPA's misdeed

An op-ed in yesterday's P-I accuses Cantwell of putting the nation's inland waters at risk, by introducing a bill to eliminate an EPA requirement that ships treat their ballast before discharging it.

This seems odd given that Cantwell threatened a one-woman filibuster when the so-called Magnuson Amendment (which effectively bans oil supertankers from Puget Sound) was proposed for repeal.

So, does Cantwell care about the quality of the water in Puget Sound or not?
