Administrator William D. Ruckelshaus of the Environmental Protection Agency has proposed national air quality standards for 6 common classes of air pollution: sulfur oxides, particulate matter, carbon monoxide, photochemical oxidants, nitrogen oxides, and hydrocarbons. The standards are designed to protect public health and welfare by setting limits on levels of pollution in the air. They apply to all areas of the United States.
Ruckelshaus also announced publication of an advance notice of proposed rule-making indicating the agency's intention of proposing regulations affecting use of lead additives in gasoline. He explained that the anticipated regulations would ultimately result in the elimination of lead additives from gasoline.
