"An EPA spokesman did not immediately respond to a request for comment."  Good.  It's about time the EPA understands they are not a branch of government.  We have three branches of government not four.  The Constitution does not empower the EPA to write laws.  The Legislature is empowered to write the laws of the nation and the Executive makes sure the laws are enforced.  Once the nominees are approved,  there will be strong leadership to run Departments that have overstepped their authority.
