So the EPA should be able to make rules and then say," Because...this". What is this? No one knows.
Making rules, regulations and public police is serious business and should be done open and above board.If you want to restrict or prohibit something, you should have real science, available science to back it up. All this garbage about privacy is just that. Scientific studies are done all the time protecting the patient's info and is perfectly acceptable science.
I think they don't want to be forced to show their work...just write down "the answer".
