Environmental Protection Agency at Pocono

The Environmental Protection Agency was reported to be at Pocono Raceway two weeks ago. It is unclear what its inspectors might have been interested in. The EPA would like NASCAR to switch to unleaded gasoline, which Formula One runs on. And NASCAR has had engine builders experiment with engines using unleaded gas, but there has been no timetable for any changeover. However Canadian law would require NASCAR to run unleaded gasoline in any race north of the border, which NASCAR has listed as its next frontier. Winston Salem-Journal
