Answer;
-The Clean Air Act and the Superfund
Step-by-step explanation;
-Superfund is a United States federal government program designed to fund the cleanup of sites contaminated with hazardous substances and pollutants.
-The Clean Air Act is a U.S. federal law intended to reduce air pollution and protect air quality. The act deals with ambient air pollution (that which is present in the open air) as well as source-specific air pollution (that which can be traced to identifiable sources, such as factories and automobiles).
-The act sets standards for air quality that limit the amount of various pollutants to specified levels. It also sets deadlines for governments and industries to meet the standards.
