1050.1 Desk Reference

This Desk Reference provides explanatory guidance for environmental impact analysis performed to comply with Council on Environmental Quality (CEQ) Regulations for Implementing the Procedural Provisions of the National Environmental Policy Act (CEQ Regulations) (40 Code of Federal Regulations (CFR) parts 1500-1508), U.S. Department of Transportation (DOT) Order 5610.1C, Procedures for Considering Environmental Impacts, and Federal Aviation Administration (FAA) Order 1050.1 Environmental Impacts: Policies and Procedures.

This Desk Reference is designed to complement FAA Order 1050.1 and should therefore be used in conjunction with the Order. FAA Order 1050.1 defines basic terms that are used throughout the Order and this Desk Reference. In addition, FAA Order 1050.1 outlines the requirements under the FAA's National Environmental Policy Act (NEPA) implementing procedures.

The Desk Reference is designed to be updated regularly based on changes to existing environmental laws and regulations. The Desk Reference chapters may be updated independently, as needed. The full version will always contain the most up to date chapters. Each chapter will indicate date of revision within the document. In addition, each individual chapter is listed below indicating the date of revision.

Version 3 of the Desk Reference includes updates, modifications, and clarifications to the February 2020 version based on its review by representatives from across the Federal Aviation Administration lines of business as well as to reflect new policy and guidance.
