Regulated Interbasin Transfers

Overview

An interbasin transfer moves water between river subbasins to address shortages or optimizes resource use for development. In 1993, the North Carolina Legislature enacted General Statute G.S. §143-215.22I as part of An Act to Regulate Interbasin Transfers (Session Law 1993-348). This law mandates that any large surface water transfers between river basins require a certificate from the Environmental Management Commission. Specifically, a transfer certificate is necessary for new transfers of 2 million gallons per day (MGD) or more. However, facilities that were operational or under construction before July 1, 1993, are exempt from this requirement, allowing them to transfer water up to their full capacity without needing a certificate.
