SB 384 — "2025 Safe Drinking Water Act" (2025)

Status: Passed 1st Reading (introduced Feb 14, 2025)
Subjects: Commissions; Environment; Hazardous Substances; Public Health; Pollution; Water Resources

Main purpose

Require the North Carolina Commission for Public Health to adopt state maximum contaminant levels (MCLs) for certain toxic contaminants in public drinking water and to establish an ongoing process to review and update standards based on peer‑reviewed science and other state guidance, with an emphasis on protecting vulnerable populations.

Key provisions

  • Rulemaking deadline: The Commission for Public Health must commence rulemaking no later than October 15, 2025.
  • Required contaminants: At minimum, the Commission must establish MCLs for:
    • PFAS (per‑ and polyfluoroalkyl substances)
    • PFOA (perfluorooctanoic acid)
    • PFOS (perfluorooctane sulfonate)
    • Hexavalent chromium (chromium‑6)
    • 1,4‑Dioxane
  • Additional contaminants: The Commission must consider setting MCLs for any other contaminants for which at least two other states have already set MCLs or issued guidance.
  • Scientific standard and sources: In developing MCLs the Commission must review:
    • MCLs adopted by other states and the supporting studies they used
    • Materials from the Agency for Toxic Substances and Disease Registry (ATSDR)
    • The latest peer‑reviewed science and government/independent studies
  • Protective requirement: State MCLs must be protective of public health — explicitly including vulnerable subpopulations (pregnant and nursing mothers, infants, children).
  • Federal floor: State MCLs may not exceed any MCL or health advisory established by the U.S. Environmental Protection Agency (EPA).
  • Ongoing review: The Commission must annually review the scientific literature and undertake further rulemaking as needed to establish or revise MCLs for contaminants that present substantial public‑health threats.
  • Reference: "MCL" defined as under G.S. 130A‑313 (state public‑health code definition).

Who is affected

  • Commission for Public Health (primary implementing agency)
  • Public water systems and utilities (monitoring, reporting, compliance, and potential treatment upgrades)
  • Municipalities and local health departments
  • Regulated industries and facilities that may contribute contaminants to water supplies (potentially facing discharge or remediation implications)
  • Consumers — particularly vulnerable groups who the standards explicitly aim to protect

Procedural / timeline notes

  • Commission must begin formal rulemaking action by Oct 15, 2025.
  • Annual scientific review is required, with additional rulemaking as necessary thereafter.
  • The bill sets process and substantive constraints (e.g., cannot set MCLs less protective than EPA advisories).

Potential impacts and considerations

  • Public-health benefit: Earlier state standards for PFAS, chromium‑6, 1,4‑dioxane, etc., could reduce exposure and health risk, especially for vulnerable populations.
  • Compliance costs: Utilities may face new monitoring, treatment, infrastructure, and reporting expenses; costs will vary by system size and contamination levels.
  • Regulatory alignment: The requirement to consider other states’ MCLs and the EPA’s guidance aims to balance state leadership with federal consistency.
  • Implementation: Exact economic and operational impacts will depend on the MCL values adopted and timing of compliance requirements; affected entities should monitor Commission rulemaking and participate in the process.

If you want, I can:
- Track the Commission’s rulemaking notices and provide alerts;
- Produce a short compliance checklist for public water systems;
- Draft talking points for a public‑utility or local government hearing on the rulemaking.
