The Ozone Transport Commission (OTC) is a multi-state organization created under the Clean Air Act (CAA). We are responsible for advising EPA on transport issues and for developing and implementing regional solutions to the ground-level ozone problem in the Northeast and Mid-Atlantic regions.

OTC brings together the states from Virginia to Maine to coordinate reductions in air pollution that benefit the whole region. We provide air pollution assessment, technical support and a forum through which states can work together to harmonize their pollution reduction strategies. OTC members include: Connecticut,Delaware, the District of Columbia, Maine, Maryland,Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania,Rhode Island, Vermont, and Virginia.

We invite you to take a look at our website where you can learn more "About Ozone" or search through our archive of projects by "Topic." If you are looking for a specific "Document" you can find that here too! If you have any questions, please send us an email to ozone@otcair.org or call our office in Washington DC at (202) 508-3840.
