What are the Federal regulations regarding ground-level ozone?
Ground-level ozone is the main component of urban smog. It is formed by the photochemical reaction of volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the atmosphere. In order to reduce ozone levels, the Clean Air Act regulates man-made emissions of both VOCs and NOx. In order to reduce ozone levels, federal and state agencies have developed regulations to reduce VOC emissions from a variety of sources, including products that contain solvents.
