The EPA has been claiming high ozone levels in Colorado are due to Utah coal plants (who don’t have scrubbers on them).
Utah’s legislature agreed something needed to be done and set aside $2 million — for legal fees to sue the EPA and avoid the extra cleanup.

Utah has some of my favorite places earth. It’s almost painful how beautiful it can be. It really is a shame what the government there does.
