The Lake Michigan Air Directors Consortium (LADCO) was established in 1990 by the states of Illinois, Indiana, Michigan and Wisconsin with Ohio being added in 2004. The purpose of LADCO is to provide technical assistance to its member states on issues related to air quality.


Ohio, Illinois and Indiana have each adopted Architectural and Industrial Maintenance (AIM) coating VOC limits consistent with those in the OTC Model Rule 2002. Michigan and Wisconsin continue to follow the EPA National Rule.
