Ozone Transport Commission (OTC) Rules

 

Current members include: Conneticut, Delaware, the District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont and Virginia. The controls placed on Architectural and Industrial Maintenance (AIM) coatings have been implemented in the OTC in the form of model rules which define the VOC content of various coating categories. Currently, two model rules are available: Model Rule 2002 and Model Rule 2010. Each participating state independently elects to adopt a model rule. All states have adopted Model Rule 2002 with the exception of Vermont which still follows the EPA National Rule and Virginia for which only select areas have adopted. Since 2017, several states have adopted Model Rule 2010 including Maryland, Delaware, Connecticut and Rhode Island. And, although Utah is not part of the OTC, it also has several counties that adopted Model Rule 2010, in 2015.

  • 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 date. The sell-through period may range from three years to indefinite.
