The environmental review process is a crucial component of any major infrastructure effort. As part of the Palmetto Commerce Interchange project, Charleston County will engage relevant agencies and stakeholders, in addition to the general public, to ensure decisions are made in the best overall public interest.

Charleston County, in accordance with the National Environmental Policy Act (NEPA), will consider the need for: safe and efficient transportation; social, economic, and environmental impacts; and national, state and local environmental protection goals. The in-depth process will take the better part of a year, as the project team engages key stakeholders and agencies, in addition to the general public, and develops alternatives for the best overall public outcome

Once an alternative has been selected, detailed design and right-of-way plans have been developed, and further public comments have been received during a public hearing in spring 2019, the project will be reviewed for final approval by the Federal Highway Administration.
