7 C.F.R. § 1b.11
(a) Definitions. As used in this part, terms have the meanings provided in NEPA section 111, 42 U.S.C. 4336(e). The following definitions apply to this part. USDA subcomponents shall use these terms uniformly throughout the Department.
(11) Design criteria (or design elements, design features, or conservation practices etc.) means constraints or requirements proactively added to the proposed action (or action alternatives) or through an iterative interdisciplinary process to avoid or minimize adverse impacts. The need for design criteria is informed by the need to comply with other laws, regulations, or executive orders; interdisciplinary discussions that identify best management practices or other design recommendations; feedback from the public or external parties; or other input provided during proposed action development and preliminary effects analysis phases. When design criteria are added in response to an issue, that issue should no longer be analyzed in detail in the analysis process. Design criteria include:
(12) Effects or impact means changes to the human environment from the proposed action or action alternatives that are reasonably foreseeable and have a reasonably close causal relationship to the proposed action or alternatives.
(29) Mitigation (or mitigation measure) means constraints or requirements that avoid, minimize, or compensate for adverse impacts caused by a proposed action or selected alternative. Mitigations are documented in a finding of no significant impact or record of decision and are determined by the responsible official in reaction to the effects described in an environmental assessment or environmental impact statement. While NEPA requires consideration of mitigation, it does not mandate the form or adoption of any mitigation. Mitigation includes:
(50) Significance means considering whether the reasonably foreseeable impacts of the proposed action are significant and analyzing the potentially affected environment and degree of the effects of the action.
(ii) In considering the degree of effects, USDA subcomponents should consider the following, as appropriate to the specific action and in the context of the potentially affected environment:
(iii) In providing rationale for whether the degree of effect is significant, responsible officials shall consider:
