U.S. Department of Agriculture (USDA)
The following categorical exclusions require NEPA documentation, which will be completed as set forth at § 1b.3(g).
Exclusion Text
(USDA-19d-NRCS) Increasing the freeboard (which is the height from the auxiliary (emergency) spillway crest to the top of embankment) of an existing dam or dike, originally built to NRCS standards, by raising the top elevation in order to meet current safety and performance standards. The purpose of the safety standard and associated work is to ensure that during extreme rainfall events, flows are confined to the auxiliary/emergency spillway so that the existing structure is not overtopped which may result in a catastrophic failure. Elevating the top of the dam will not result in an increase to lake or stream levels. Work will be confined to the construction footprint of the dam and abutment areas, and no major change in reservoir operations will result. Examples of work may include the addition of fill material such as earth or gravel or placement of parapet walls.

This CE Explorer tool is not an authoritative source and creates no rights or obligations. Review the relevant agency's NEPA procedures before applying a categorical exclusion.
When using the CE Explorer Tool, Federal agencies and stakeholders should review the relevant agency's NEPA procedures for information about how to apply the CE, including any limitations or potential extraordinary circumstances, and to ensure that a CE is current and applicable to a given proposed action. To adopt and use another agency's categorical exclusion, an agency must follow the steps described in section 109 of NEPA, 42 U.S.C. 4336c.
