With respect to past actions by adding up all prior actions on an action- actions, during the scoping process and subsequent by-action basis. Several reasons exist for not taking preparation of the analysis, the agency must this approach. First, a catalog and analysis of all determine what information regarding past actions past actions would be impractical to compile and is useful and relevant to the required analysis of unduly costly to obtain. Current conditions have been cumulative effects. Cataloging past actions and affected by innumerable actions over the last century specific information about the direct and indirect (and beyond), and trying to isolate the individual effects of their design and implementation could in actions that continue to have residual effects would some contexts be useful to predict the cumulative be nearly impossible.
