SEC. 1508.7 CUMULATIVE IMPACT.

[Rachel's introduction: Section 1508 of 40 CFR [Code of Federal Regulations] codifies the terms and processes of environmental impact statements. The legal authority for this is found in 43 FR [Federal Register] 56003, Nov. 29, 1978.]

"Cumulative impact" is the impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (Federal or non-Federal) or person undertakes such other actions. Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time.
