The EPA is considering lowering the National Ambient Air Quality Standards for ozone from 75 parts per billion to 60 parts per billion, which would cause 97% of US counties to be out of compliance. This would give the EPA authority to regulate industries that emit ozone, like oil and gas, costing over $1 billion per year to comply and destroying millions of jobs. At 60 parts per billion, the standard would be below natural background ozone levels, making it an impractical and unachievable target that could bankrupt businesses trying to comply with impossible regulations.
