The Office of Pipeline Safety (OPS) proposes to revise § 192.615 to clarify and delineate the existing requirement that an operator prepare and execute an emergency plan. An emergency plan is necessary to provide for a timely and appropriate response by an operator in an emergency involving or likely to involve a gas pipeline facility. The existing requirements In § 192.615 have been In effect since November 12, 1970 (35 FR 13248). They are based in part on the recommended standard in section 850.6 of the 1968 edition of the United States of America Standards nstitute B31.8 Code.
