"As Environmental Protection Agency chief Scott Pruitt has moved to roll back a sweeping array of Obama-era regulations he's relentlessly cited his goal of providing 'regulatory certainty.'

In his first address to career employees last year he told the gathered room at the EPA, 'Regulators exist to give certainty to those that they regulate. Those that we regulate ought to know what we expect of them, so that they can plan and allocate resources to comply.'

He's cited this in his efforts to delay, repeal or roll back the Clean Power Plan, the Waters of the U.S. Rule, and a string of other measures."
