The National Environmental Policy Act (NEPA) ensures the proper evaluation of environmental impacts from mining projects.

The National Environmental Policy Act (NEPA), passed in 1970, requires federal agencies to assess the environmental impacts of proposed mining projects (and other major federal actions) before they proceed. NEPA mandates the preparation of an Environmental Impact Statement (EIS) or Environmental Assessment (EA) to analyze the potential effects on air, water, wildlife, and other aspects of the environment. This process ensures that environmental concerns are fully considered and mitigated, promoting informed decision-making and public involvement. NEPA plays a critical role in balancing economic development with environmental protection, ensuring that mining projects are sustainable and responsible.
