It's not something you want to think about: excrement floating in our lovely oceans. Some boaters release their sewage into the water, but Washington's Department of Ecology is trying to change that. They are drafting a petition to the Environmental Protection Agency to classify the Puget Sound as a "no discharge zone." If approved, it would prohibit boaters from releasing any sewage — treated or untreated — in the Sound. Ross Reynolds talks with Department of Ecology supervisor Mark Henley.
