I had to read this article from The Oregonian twice to make sure I got it right. Apparently the EPA did not consider ballast contaminated with invasive species to be covered under the Clean Water Act. A federal judge has overturned EPA regulations exempting ships from acquiring a permit before dumping ballast water, and now the organization that is supposed to be protecting the environment is expected to appeal the ruling. Not that I think it makes sense from an economic or technological standpoint to suddenly demand that all incoming ships treat their ballast water to kill any potential invasive species. It's just that this is not the same EPA I grew up with.
