33 C.F.R. § 230.6 Actions normally requiring an EIS.
Title 33 - Navigation and Navigable Waters
Actions normally requiring an EIS are: (a) Feasibility reports for authorization and construction of major projects; (b) Proposed changes in projects which increase size substantially or add additional purposes; and (c) Proposed major changes in the operation and/or maintenance of completed projects. District commanders may consider the use of an environmental assessment (EA) on these types of actions if early studies and coordination show that a particular action is not likely to have a significant impact on the quality of the human environment.
