The bill S. 139 aims to amend the South Carolina Code of Laws by adding Section 48-1-91, which mandates that any individual or entity holding a National Pollutant Discharge Elimination System (NPDES) permit for discharging effluent into state waters must post a conspicuous sign. This sign must be visible from the receiving water and include specific information such as the words "Treated Wastewater" or "Cooling Water," the permittee's name and facility, the permit number, and contact numbers for both the permittee and the reporting department. The bill also outlines exemptions for certain discharges, such as those composed exclusively of stormwater or associated with specific NPDES General Permits.

Additionally, the bill provides a process for permit holders to apply for waivers from the sign-posting requirements under certain circumstances, including if the sign would conflict with other laws or if the outlet is on restricted property. The sign must be posted within twelve months of the act's effective date, and the department is tasked with notifying all NPDES permit holders of these new requirements by November 29, 2025. The act will take effect upon the Governor's approval.
