The mission of the Indiana Department of Environmental Management's Office of Air Quality implements federal and state regulations to protect human health and the environment while allowing the environmentally sound operations of industrial, agricultural, commercial and governmental activities vital to a prosperous economy. The mission of the Office is to assure that the air in Indiana meets the National Ambient Air Quality Standards (NAAQS) for each of the six criteria pollutants regulated by the federal Clean Air Act (CAA); to provide timely, quality air permits without unnecessary requirements and to verify compliance with applicable state and federal air pollution laws and regulations.
OAQ is comprised of five branches, each with specific air quality responsibilities. Most branches in OAQ are divided into sections that handle certain aspects of branch responsibilities.
The Office implements and enforces rules established by the Environmental Rules Board, which was created by the 2012 Indiana General Assembly and consolidates the Air Pollution Control Board, Water Pollution Control Board, and Solid Waste Management Board.
