Air quality assessments for proposed Federal actions are required for compliance with the National Environmental Policy Act (NEPA), the Clean Air Act, and other environment-related regulations and directives. This handbook is a comprehensive guide intended to assist the air quality analyst/environmental specialist in assessing the air quality impact of Federal Aviation Administration and the United States Air Force actions at airports and air bases.  The purpose of this handbook is three-fold: 

• To provide guidance, procedures, and methodologies appropriate for use in carrying out air quality assessments prepared in association with FAA Federal Actions; 
• To help ensure that these air quality assessments meet the requirements of the National Environmental Policy Act (NEPA), the federal Clean Air Act (CAA), and other applicable laws and regulations; and 
• To provide a process for users to determine when an air quality assessment is considered necessary, the type of analysis that is appropriate, and the level of effort that is warranted.
