Rule Aims To Maintain Or Improve Safety
PHMSA concludes adopting MSS SP-75-2025 will maintain or improve public safety, prevent regulatory confusion, and facilitate safety-focused allocation of operator resources. PHMSA also states the update helps align regulations with innovations in materials, testing, and practices.
Operators Must Use MSS SP-75‑2025
If you operate pipeline facilities, PHMSA replaces the MSS SP-75-2019 reference with MSS SP-75-2025 (published June 2025). The updated MSS SP-75 standard will be incorporated into 49 CFR part 195 and is effective January 1, 2027; adverse comments must be received by June 23, 2026.
No Expected New Compliance Costs
PHMSA states that most pipeline operators already follow the updated standard and expects compliance costs to be negligible or that the rule may yield minimal cost savings. PHMSA estimates the total costs on the regulated community will be "less than zero."
