Ted Cruz has a plan to fix an environmental regulation Texas oil refiners hate. Yet Cruz’s plan has not been widely embraced by the very industry he’s trying to help.Texas’ powerful oil and gas sector detests the Environmental Protection Agency’s Renewable Fuel Standard, which mandates that transportation fuel contain a certain quantity of renewable fuels. Cruz’s aggressive attempts to unravel that policy — by taking his case to the White House — could offer the quickest path to changes the industry wants.Rather than work with a divided Senate, Cruz is appealing to Trump’s anti-regulatory EPA to change a small piece of the 2005 regulation, a piece most in the energy industry believe would blow up the entire policy Cruz has long sought to abolish.
