U.S. EPA has directed six natural gas producers in Pennsylvania to disclose how they intend to dispose of their drilling wastes. "EPA’s action follows a request by PADEP asking drillers to voluntarily stop taking wastewater to Pennsylvania wastewater treatment plants by May 19. EPA wants to know where drillers are now going to dispose of their wastewater and will work with PADEP to ensure EPA has access to this information."

It's starting to look like a frontal assault.
