What the frack? Via the Los Angeles Times, Diesel is used in fracking without permits, report says:
Energy companies have used thousands of gallons of diesel to frack for oil and gas without obtaining the necessary permits required under federal law, according to a new report by the Environmental Integrity Project.
The watchdog group's review of industry and federal data from 2010 to 2014, released Wednesday, found 351 wells in 12 states that used diesel in fracking. [...] The EPA said it was reviewing the integrity project's report.
Oh em gee, the GOP is right! It's all so clear now. What we need is less oversight.
