Context triple: [Nonattainment New Source Review program, legalBasis, Part D of Title I of the Clean Air Act]

A. Clean Air Act
The Clean Air Act is a landmark U.S. federal law that regulates air emissions from stationary and mobile sources to protect public health and the environment from air pollution.
B. National Ambient Air Quality Standards
The National Ambient Air Quality Standards are U.S. federal air pollution limits that set maximum allowable concentrations of key pollutants in outdoor air to protect public health and the environment.
C. Clean Air Interstate Rule
The Clean Air Interstate Rule was a U.S. Environmental Protection Agency regulation aimed at reducing interstate air pollution from power plants, particularly sulfur dioxide and nitrogen oxides that contribute to fine particulate matter and ozone.
D. Regulation 14 on sulfur oxides and particulate matter
Regulation 14 on sulfur oxides and particulate matter is a key provision in international maritime environmental law that sets limits on sulfur content in marine fuels and controls emissions of sulfur oxides and particulates from ships to reduce air pollution.
E. Pollution Prevention Act of 1990
The Pollution Prevention Act of 1990 is a U.S. federal law that established a national policy prioritizing source reduction and environmentally sound practices to prevent pollution before it is created.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
