2019-9-20 · Coal has been considered a dirty fuel for a long time. It caused the famous 19th century London fogs, and it killed 19 people in Donora, PA in 1948 when a temperature inversion trapped smoke from the surrounding steel mills against the ground. The latter incident helped to get pollution control regulations off the ground, even though there had been sporadic attempts as far back as 1306.
