LADCO Certification
Lake Michigan Air Directors Consortium Standards
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.
Lake Michigan Air Directors Consortium
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.
LADCO Exemptions:
- Small container exemption allows the sale of coatings above maximum VOC limits if packaged in containers of one liter or less.
- Sell-through provision allows the sale of coatings above the maximum VOC limits if manufactured prior to the individual state rule's effective data. The sell-through period may range from three years to indefinite.
