Hazardous Air Pollutants Program
The Hazardous Air Pollutants Program is specifically dedicated to the collection and dissemination of data about hazardous air pollutants in Maine. Hazardous air pollutants are those that, in sufficient concentration, could cause serious health effects to people or have serious adverse effects upon the environment. In order to help protect the health of Maine residents and preserve our environment, the Department of Environmental Protection has developed this web site to help enlighten Maine's public as to the dangers associated with hazardous air pollutants.
