Which legislation did NOT directly impact how federal agencies comply with Environmental Standards?

The National Environmental Policy Act of 1969 (NEPA) is primarily focused on ensuring that all branches of government consider the environment before undertaking any major federal actions that significantly affect the environment. NEPA requires federal agencies to assess the environmental effects of their proposed actions, but it does not directly set environmental standards like pollution limits or specific operational guidelines. Instead, NEPA operates as a procedural framework for federal decision-making, emphasizing transparency and public involvement in the environmental review process.

In contrast, the Clean Water Act, the Clean Air Act, and the Resource Conservation and Recovery Act are all pieces of legislation that establish specific regulatory standards for environmental protection, including detailed criteria for water quality, air quality, and waste management. These acts contain enforceable regulations that agencies must follow, thereby directly shaping how federal agencies ensure compliance with environmental standards.
