EPA to Hold Public Hearings on Air Quality Standards for Smog
EPA will hold 3 public hearings on the proposal to strengthen the nation's air quality standards for ground-level ozone, also called smog. The agency is proposing to set the "primary" standard, to protect public health, at a level between 0.060 and 0.070 parts per million measured over eight hours. EPA is also proposing to set a separate, seasonal "secondary" standard to protect the environment, especially plants and trees.
