Environmental Assessment, 2nd Edition

This appendix presents a simplified flowchart of the steps which will be completed if a systematic approach to preparation of environmental documentation is to be followed (Fig. C.1). The major steps are presented in a sequential fashion, using hypothetical examples.
Many different methodologies for impact assessment exist, both in theory and in practice, as discussed in Chapter 6. This appendix presents one simplified, systematic approach to the development of an environmental impact analysis, utilizing the matrix approach and the multidisciplinary attribute descriptor package from Appendix B. Although the matrix method is employed, similar procedures using environmental attributes could be developed, and the reader s attention is directed to those places where variation is normally found.
The following steps, as shown in Fig. C.1, detail the procedure to be used in preparing environmental assessment documentation. The degree of consideration to be exercised within some of the steps may vary with project scope and magnitude, but the basic algorithm is applicable in all cases
The first step in the assessment process for either an environmental impact statement or an environmental assessment is to determine what the proposed action is, and identify the purpose and need that it addresses. At first glance, this step may seem unnecessary. However, often this is the most difficult step of the process, and may mean the difference between agency success or failure if a court or administrative law judge reviews the assessment.
