Non-Programmatic Categorical Exclusion,
April 2026
The National Environmental Policy Act (NEPA) requires federal agencies to consider the impacts their projects may have on the environment and to integrate the NEPA process with other environmental law compliance. In association with the Federal Highway Administration (FHWA) and Beaufort County, SCDOT has developed a Non-Programmatic Categorical Exclusion in accordance with NEPA. This document is the culmination of technical studies and reports, interagency coordination, and community outreach and feedback. The Non-Programmatic Categorical Exclusion documents the purpose and need for the project and presents a Recommended Preferred Alternative. It also incorporates analysis and feedback from public and agency sources gathered during the various phases of the project development.
