This amendment modifies § 192.313 of' the Federal gas pipeline safety standards and § 195.212 of the Federal liquid pipeline safety standards to provide more appropriate safety requirements for steel pipe which is subjected to field bending. This amendment also makes the standards for bending pipe in gas and liquid service consistent insofar as practicable. In addition, the existing restrictions on wrinkle bends and filtered bends in § 195.212(e) are restated in a new § 195.212 (a) and § 195.216, respectively. This proceeding was begun by the Office of Pipeline Safety (OPS) which issued an advance notice of proposed rulemaking, Notice 73-1 (38 FR 14969, June 7,1973), to gain additional information on pipe bending before formulating proposed amendments to the existing rules. (However, after the advance notice was issued, OPS was abolished, and the authority to administer pipeline safety matters was delegated to the Director, Materials Transportation Bureau (MTB) (40 PR 30821, July 23, 1975).
