Does the EPA regulate human crematories?
As a result of the Clean Air Act of 1990, the Environmental Protection Agency first classified crematories as medical waste incinerators, then later as OSW (Other Solid Waste) incinerators. After an intensive, costly and aggressive testing project in 1999 on working crematories that covered most types of emissions, including particulate matter, carbon monoxide and mercury, done jointly with the Cremation Association of North America and reviewing information presented, the EPA decided not to regulate human or animal crematories.
