(a) This subpart implements NEPA, setting forth NASA's policies and procedures for the early integration of environmental considerations into planning and decision making.

(b) Through this subpart, NASA adopts the CEQ regulations implementing NEPA (40 CFR parts 1500-1508) and supplements those regulations with this subpart 1216.3, for actions proposed by NASA that are subject to NEPA requirements. This subpart is to be used in conjunction with the CEQ regulations. Consistent with the CEQ regulations at 40 CFR part 1500.3, no trivial violation of this part shall give rise to any independent cause of action. This subpart and NASA's NEPA policy are available on NASA's Public Portal at http://www.nasa.gov/agency/nepa/ (under NEPA Process).
