Abstract Description: The U.S. Air Force air pollution problems often mirror their civilian counterparts. The National Ambient Air Quality Standards apply to both, both deal with hazardous air pollutants, and greenhouse gas emissions must be considered by both. But the overall work objectives are quite different, terminology is different, the Air Force must also deal with regulations on an international basis, and even in the U.S., the requirements differ. For example, the Air Force must meet the federal requirements outlined by the National Environmental Policy Act and the Council on Environmental Quality regulations. The Air Force requirements have been implemented under 32 CFR Part 989 and are named the Environmental Impact Analysis (EIAP). This framework must be followed in the U.S. as well as outside the U.S. But the actions are different depending on whether in or outside of the U.S. Further requirements are also included in the Department of Defense Directive (DoDD) 4715.1, Environmental Security, Department of Defense Instruction (DoDI) 4715.9, Environmental Planning and Analysis and DoDD 5000.1, Defense Acquisition, and Department of Defense Regulation 5000.2-R, Mandatory Procedures for Major Defense Acquisition Programs and Major Automated Information System Acquisition Programs. Many other specific military requirements also apply for the Air Force. This is only one example, The paper will discuss these difference and others such as the different sources of pollutants, analysis differences, and model differences.
