A bill to amend the Clean Air Act with respect to the prevention and control of air pollution in border areas of the United States and countries contiguous to the United States.

Amends the Clean Air Act to direct the President, acting through the Secretary of State, to enter into negotiations with countries contiguous to the United States to: (1) prevent and control air pollution in U.S. border areas; and (2) reduce or eliminate air pollution which originates in such other countries and affects any U.S. area. Declares it to be the sense of the Congress that such goals should be achieved as soon as feasible through treaties or other appropriated international agreements and diplomatic actions.

Directs the Administrator of the Environmental Protection Agency to determine the percentage of air pollutants in border areas resulting from foreign sources and to eliminate such percentage in determining compliance with ambient air quality standards by such region.
