The U.S. Environmental Protection Agency issued a code red warning for air quality over much of the Mid-Atlantic region, including Washington, D.C., on June 11, 2002. The EPA warning means that the air is classified as either “Unhealthy” or “Unhealthy for Sensitive Groups,” according to the EPA’s index.
