An Environmental Impact Statement (EIS) is required by which act when significant environmental impact is indicated?

An Environmental Impact Statement (EIS) is primarily associated with the National Environmental Policy Act (NEPA). This federal law, enacted in 1969, mandates that federal agencies assess the environmental effects of their proposed actions before making decisions. The intent of an EIS is to inform decision-makers and the public of the potential environmental impacts of a project and explore alternatives and mitigation measures.

NEPA requires an EIS to be developed when a federal project is likely to have significant environmental impacts. This extensive review process helps ensure that environmental factors are considered alongside economic and technical factors in decision-making, contributing to sustainable development. Therefore, the correct association of the EIS requirement with NEPA reflects the act's commitment to promoting informed environmental governance and public involvement in federal decision-making processes.
