In March 2013, DHEC identified a preferred cleanup alternative for the Congaree River sediments and soils as No. 4 - Removal of the TLM and Impacted Sediments.
Federal and state laws govern activities in (or affecting) navigable waters, therefore various permits will be required if it were selected as the final cleanup alternative.

The permit processes require SCE&G to submit detailed information for the project addressing, but not limited to, the following:
During the permitting process, several significant design issues with the cofferdam were identified and caused the need for a re-evaluation of the proposed removal action. These issues included:
DHEC is currently re-evaluating the cleanup alternatives outlined in the Engineering Evaluation/Cost Analysis (EE/CA).Â The Administrative Record includes documents that DHEC is using to evaluate the alternatives.
