Investopedia explains 'Filthy Five'


The Filthy Five are exempt from modern pollution regulations because they were grandfathered in under the old laws. They produce large amounts of sulfur, carbon dioxide, nitrogen dioxide and mercury. The governor of Massachusetts came under political pressure to do something about these plants and issued an edict requiring them to adhere to modern pollution regulations.
