In compliance with the National Environmental Policy Act (NEPA) and Council on Environmental Quality (CEQ) regulations (40 CFR 1508.25(c)), the indirect and cumulative effects of a project should be examined along with the direct impacts.
Indirect effects are caused by an action and occur later in time or farther removed in distance, but are still reasonably foreseeable.
Cumulative effects are the impact on the environment that results from the action when added to other past, present and reasonably foreseeable future actions, regardless of what agency (federal or nonfederal) or person undertakes such actions.
The Maryland State Highway Administration has developed an interactive training presentation to provide users with consistent procedures in conducting an ICE analysis, as well as a clear definition of direct impacts and indirect and cumulative effects.
