On August 8, the American Lung Association, the Environmental Defense Fund, the Natural Resources Defense Council, the National Parks Conservation Association, and the Appalachian Mountain Club filed a motion with the U.S. Court of Appeals for the D.C. Circuit to order the Environmental Protection Agency to immediately sign revised air quality standards for ozone, which the agency has delayed four times. Then, on August 11, thirteen states filed a motion supporting the interest groups, with New York, California, Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New Mexico, Oregon, and Rhode Island, as well as the District of Columbia and New York City filing together. When a rule was proposed in January 2010 to revise the standards, EPA said it intended to issue the final rule by August 2010, but delayed it further in announcement this July.
