Which act requires federal agencies to assess environmental impacts of proposed actions?

• A. Clean Air Act
• B. Endangered Species Act
• C. National Environmental Policy Act
• D. Federal Insecticide, Fungicide, and Rodenticide Act

Answer: (D)

The main idea is that federal decisions must be evaluated for their environmental consequences before they are approved. This requirement comes from the National Environmental Policy Act, which obligates federal agencies to prepare environmental assessments or, for actions with significant impacts, environmental impact statements. These documents examine possible environmental effects, consider alternatives, propose mitigation measures, and often invite public input. This process ensures environmental factors are considered in decision-making for major federal actions.

The other acts don’t provide this overarching procedural framework. The Clean Air Act focuses on reducing air pollution by setting national standards and requiring permits and plans to meet those standards; it isn’t about conducting a broad environmental impact analysis of every proposed federal action. The Endangered Species Act aims to protect endangered species and requires agencies to ensure their actions don’t jeopardize those species or destroy critical habitats, but it doesn’t mandate a general environmental impact assessment of all actions. The Federal Insecticide, Fungicide, and Rodenticide Act regulates pesticides through registration and labeling and assesses pesticide risks, rather than requiring a broad, mandatory environmental impact assessment for federal actions.
