Petition of the day
The petition of the day is:
Issue(s): Whether the Environmental Protection Agency may establish a new National Ambient Air Quality Standard under the Clean Air Act based on a purely hypothetical threat to the public health, as the D.C. Circuit held, or whether the agency is instead limited to establishing standards that are necessary to protect the public health from an actual or reasonably anticipated threat of harm.
