    Glossary of Terms

    Environmental Impact Statement (EIS)
    An EIS is prepared when a proposed action or alternatives have the potential for significant effect on the human environment.

    Environmental Assessment (EA)
    An EA is prepared to determine whether the impact of a proposed action or alternatives could be significant.

    Record of Decision (ROD)
    The document that is prepared to substantiate a decision based on an EIS. It includes a statement of the decision made, a detailed discussion of decision rationale, and the reasons for not adopting all mitigation measures analyzed, if applicable.

    Finding of No Significant Impact (FONSI)
    A determination based on an EA and other factors in the public planning record for a proposal that, if implemented, would have no significant impact on the human environment.

    The procedure by which an agency identifies important issues and determines the extent of analysis necessary for an informed decision on a proposed action. Scoping, an integral part of environmental analysis, includes early involvement of interested and affected public, as well as internal and external agency contacts. Although formal scoping occurs for a specific time period, we welcome your comments on projects while we are in the process of preparing plans.
