Not enough. The EPA has no reason to exist. Do not simply appoint another head of an unconstitutional agency—abolish it.
Hopefully, Trump hired this guy with the understanding that he is responsible for downsizing the Agency to zero by (pick a date).
there are reasons for an EPA. the problem we have is environmental Waco have used and abused it. in the sixties and seventies we had a real problem with polluted waterways from envirmentle abuse. at the moment a combination of bad laws have made the agency a killer of business.
