In an effort to ensure that there is enough gasoline available for all Americans to squander as they please, our current business-friendly EPA has seen fit to waive certain anti-pollution standards in order to allow for less-clean gasoline to be legally sold when and where it had previously been restricted. Although called a 'temporary' change, I'm guessing this might be a continuous, or at least a recurring, event for the foreseeable future. I'd rather pay $7 per gallon than roll-back yet another anti-pollution restriction.
"The EPA late on Tuesday said it would temporarily permit refineries in Florida, Alabama, Mississippi and Tennessee to supply gasoline meeting a Reid Vapor Pressure standard of 9.0 and diesel with sulfur content higher than 500 parts per million. On Wednesday, the waiver was extended to the remaining 46 U.S. states, Johnson said. The policy change will allow more imports of high-sulfur diesel into the U.S. market. Refiners will also be able immediately to sell gasoline intended for use in the autumn and winter, when pollution caused by hotter weather is normally not a problem."
