WASHINGTON — Leon G. Billings, a former aide to Maine Sen. Edmund Muskie and a key author of the Clean Air Act and other landmark environmental laws, has died.
Billings, 78, died Tuesday in Nashville, Tennessee, after suffering a stroke while visiting family.
Born in Montana, Billings moved to Washington in 1962 and had a 50-year career in politics and public policy. As the first staff director of the Senate Environment subcommittee, Billings was a primary author of the 1970 Clean Air Act, one of the first and most influential environmental laws in U.S. history and a foundation for current air pollution laws.
