Which of the following is NOT a function of the Environmental Protection Agency (EPA)?

The function of regulating interstate commerce is not a primary responsibility of the Environmental Protection Agency (EPA). The EPA is primarily focused on protecting human health, enhancing environmental quality, and coordinating pollution abatement efforts through various regulations and programs aimed at ensuring clean air, water, and land.

The EPA's role in protecting human health involves setting and enforcing standards for pollutants and chemicals to safeguard the public from harmful exposure. Enhancing environmental quality encompasses efforts to preserve natural resources and promote sustainable practices. Coordinating pollution abatement efforts includes working with state and local agencies, industries, and communities to implement strategies for reducing pollution and managing environmental issues.

Interstate commerce, on the other hand, is mainly governed by the Commerce Clause of the U.S. Constitution and is overseen by other federal agencies. Although the EPA may influence industries that operate across state lines, its main focus is on environmental protection rather than the broader aspects of regulating commerce. Thus, stating that regulating interstate commerce is a function of the EPA is misleading since it is not central to the agency's mission.
