IZEMBEK NATIONAL WILDLIFE REFUGE 2-ii LAND EXCHANGE/ROAD CORRIDOR EIS CHAPTER 2 ALTERNATIVES 2.0 ALTERNATIVES 2.1 Introduction Chapter 2 describes the process of developing alternatives for the Izembek National Wildlife Refuge Land Exchange/Road Corridor Environmental Impact Statement (EIS). The chapter includes the alternatives carried forward for detailed evaluation, including 2 alternatives that address the proposed action, 2 additional action alternatives, and the No Action alternative; mitigation measures; and other alternatives considered and eliminated from detailed analysis. The alternative development process complies with the requirements as stated in the Council on Environmental Quality Regulations for Implementing the Procedural Provisions of the National Environmental Policy Act (NEPA). The following information is included in this chapter: • A discussion of how alternatives were developed; • Descriptions of alternatives considered but dismissed from further analysis; • Descriptions of alternatives considered in detail, including the No Action alternative; • A discussion of mitigation measures, best management practices, and associated monitoring practices that would eliminate or lessen adverse environmental impacts by alternative; • A summary comparison of the effects of the alternatives (a detailed assessment of effects is given in Chapter 4); and • Identification of incomplete and unavailable information and an examination of the impact of these data limitations on the environmental consequences analysis. 2.2 Alternative Development Process A stepwise approach was taken to develop and assess action alternatives that would meet the project purpose and needs as described in Chapter 1. The first step developed a range of alternatives that address the project purpose and need, including the issues and alternative proposals identified during the scoping process, and also comply with federal, Tribal, state, and local regulations. Alternatives carried forward for detailed consideration were guided by the key legislative directives, the Omnibus Public Land Management Act of 2009 (Act) and NEPA. Key points of the Act and NEPA, relative to alternative development, are summarized in this section; other applicable laws and regulations are summarized in Chapter 1. The steps in the alternative screening process are also summarized in this section. The
