ES‐iv CJMT EIS/OEIS April 2015 Draft Executive Summary ES.1 INTRODUCTION The National Environmental Policy Act (NEPA) requires federal agencies to examine the potential effects of their proposed actions on the human environment. The human environment includes the natural and physical environment and the relationship of people with that environment. An Environmental Impact Statement (EIS) is a detailed public document that complies with the requirements of NEPA by assessing the potential effects that a major federal action may have on the human environment. This Executive Summary presents a summary of information presented in the EIS/Overseas EIS (OEIS). A list of technical terms and definitions is presented in the Glossary. The proposed action is to establish a series of live-fire ranges, training courses, and maneuver areas within the Commonwealth of the Northern Mariana Islands (CNMI) to reduce existing joint service training deficiencies and meet the United States (U.S.) Pacific Command Service Components’ unfilled unit level and combined level training requirements in the Western Pacific. Under the proposed action, unit level training would occur on Tinian and combined level training would occur on Pagan. Use of both islands is required to meet the purpose and need for the proposed action. The proposed action includes: construction, range management, expanded training and operations (to include combined arms, live- fire, and maneuver training at the unit and combined level), establishment of danger zones, designation of Special Use Airspace, and interest in land to support simultaneous and integrated training. An OEIS is required per Executive Order 12114 when a proposed action has the potential to significantly harm the environment of the U.S. Exclusive Economic Zone, the global commons, or a foreign nation’s Exclusive Economic Zone, territorial sea, or land mass. An OEIS is warranted for the proposed action described in this document because of proposed changes to international airspace past 12 nautical miles (22 kilometers). To reduce duplication, the EIS and OEIS are combined into one document. This EIS/OEIS identifies the proposed action, along with a preferred alternative, and evaluates the potential environmental effects associated with a variety of reasonable alternatives. Each of the action alternatives, as well as the no-action alternative, is described in Chapter 2, Proposed Action and Alternatives. Several studies, reports, assessments, and international agreements have documented the need for additional training capabilities in the U.S. Pacific Command’s Area of Responsibility in the Western Pacific (Figure ES-1). Relevant documents are summarized in Section ES.2, Purpose and Need for the Proposed Action. Within the Western Pacific, the greatest need and potential opportunity for increased training capacity and capability occurs in the Mariana Islands, specifically the CNMI which is comprised of 14 islands north of Guam (Figure ES-2).
