NEPA is a Federal statute, enacted in 1969, that requires Federal agencies to evaluate the potential environmental effects of a proposed action, make informed decisions and inform and involve the public before making decisions.  Under the Ivanpah Valley Airport Public Lands Transfer Act of 2000 (Public Law 106-362), the Federal Aviation Administration (FAA) and the Bureau of Land Management (BLM) are Joint Lead Agencies (JLA) responsible for compliance with the requirements of NEPA for the proposed SNSA.
