The National Environmental Policy Act (NEPA) levies procedural requirements on NASA. To ensure proper implementation of NEPA, NASA has established a program within the Environmental Management Division to have oversight of the NEPA process and requirements at NASA. Following the NEPA procedural requirements, NASA's NEPA program has developed NASA-specific policies and procedures for the Agency. The requirements in the policies and procedures proscribe how to develop the analyses and documents that are central to the NEPA process.
NASA's NEPA policies and procedures are available to the public and have been published in the Federal Register. Publication in the Federal Register allows for public review and comment and NASA is currently working with other Federal agencies to develop updated versions of some of these publications. These updates may later be codified and published in the Code of Federal Regulations, which will then be levied on all the Federal agencies in the executive branch.
