In 2004, the state of Ohio joined LADCO, and in 2012 the state of Minnesota joined LADCO.The purposes of the consortium are to: provide technical assessments for and assistance to its member states on problems of air quality issues; provide a forum for its member states to discuss air quality issues; encourage, among its members, the exchange of knowledge, experience, and information related to air quality issues; promote communication and understanding of air quality issues and studies in cooperation with the United States Environmental Protection Agency; provide information and respond to questions related to the work of the consortium; receive and disburse funds from and to any source to further the purposes stated herein; and organize and coordinate training for its member states.
