The bill H. 4102 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 include specific information such as the type of outfall, the name of the permit holder, the permit number, and a contact number for reporting issues. The South Carolina Department of Environmental Services is tasked with developing a template and requirements for the signage, which must be durable and visible from the receiving water.

Certain exemptions are outlined in the bill, including discharges composed solely of stormwater and those associated with specific NPDES General Permits. Additionally, permit holders can apply for waivers under specific circumstances, such as if the sign would conflict with other laws or if the outlet is on restricted property. The bill stipulates that the sign must be posted within twelve months of the act's effective date and maintained thereafter. The Department of Environmental Services is also required to notify all NPDES permit holders of these new requirements by December 1, 2025.
