Lead pipe replacement law in South Carolina
South Carolina has not set its own state-specific lead service line replacement deadline beyond the federal requirement below. The rule is implemented through the South Carolina Department of Environmental Services (SCDES, DHEC's 2024 successor agency), whose own compliance date -- November 1, 2027, for an updated baseline inventory and a replacement plan -- matches the federal Lead and Copper Rule Improvements schedule exactly rather than an earlier state-specific date. Customers served by a lead, galvanized-requiring-replacement, or unknown service line must be notified annually of their service line material.
Separately from any state law, the EPA's federal Lead and Copper Rule Improvements require every water system nationwide to submit a baseline inventory and an approved replacement plan by November 1, 2027, then fully replace all lead and "galvanized requiring replacement" lines under its control on a schedule of 10 years or less from that date, replacing at least 10% of its known lead/GRR lines per year. A narrow exception allows a longer schedule only for the roughly 1% of systems with an unusually dense concentration of lead lines, and partial (non-emergency) replacements are prohibited.
