Fall scene in MaineAir Toxics Program

The Air Toxics Program is specifically dedicated to the collection and dissemination of data about air toxics in Maine.  Air toxics refers to a very broad group of air pollutants that, in sufficient concentration, could cause serious health effects to people breathing air that contains them. 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 hazards associated with air toxics.

Air Toxics Information

Air Toxics: An Overview is designed to answer basic questions about the nature of air toxics, their sources in Maine, and programs used to mitigate their impact upon the people of Maine.

NESHAP and MACT are acronymns for National Emissions Standards for Hazardous Air Pollutants (NESHAP) and Maximum Achievable Control Technology (MACT) standards which are used to control air toxics. This site provides compliance information to facilities and explains the approach used to regulate air toxics.

Maine Air Toxics Initiative is a facilitated stakeholder process aimed at identifying which air toxics are most responsible for creating health risks, the source of those pollutants, and creation of cost effective solutions to reduce the risk. Documents related to the MATI process and subcommittee activities are posted on this site.
