[Air Improvement] Malia Is Very Annoyed Because a Business near Her

[Air Improvement] Malia is very annoyed because a business near her neighborhood has an incinerator that regularly releases pollutants. She discussed the matter with her local city council representative, Leo, who told her that only the federal government can enforce laws involving pollutants; that the government has done so through the establishment of National Ambient Air Quality Standards; and that there is nothing she as an individual can do. Malia tells the council representative that she considers the emissions criminal. Leo just shrugs and replies that industry is never subject to criminal penalties under the Clean Air Act and that only the government can enforce the Clean Air Act anyway.
