Pipeline Safety: Plastic Pipe Rule

Notice of Proposed Rulemaking (NPRM).

PHMSA is proposing to amend the natural and other gas pipeline safety regulations (49 CFR part 192) to address regulatory requirements involving plastic piping systems used in gas services. These proposed amendments are intended to correct errors, address inconsistencies, and respond to petitions for rulemaking. The requirements in several subject matter areas are affected, including incorporation of tracking and traceability provisions; design factor for polyethylene (PE) pipe; more stringent mechanical fitting requirements; updated and additional regulations for risers; expanded use of Polyamide-11 (PA-11) thermoplastic pipe; incorporation of newer Polyamide-12 (PA-12) thermoplastic pipe; and incorporation of updated and additional standards for fittings.
