Notice of proposed rulemaking.
PHMSA is proposing to incorporate by reference more than 20 consensus standards into the Federal pipeline safety regulations. This notice of proposed rulemaking (NPRM) would incorporate by reference a new, updated, or reaffirmed edition of each consensus standard. This NPRM would also make non-substantive corrections to clarify regulatory language in certain provisions. These editorial changes are minor and would not require pipeline operators to undertake new pipeline safety initiatives.
