A final rule was published July 10, 179 (44 FR 41197), establishing the essentials for written procedures to be prepared and followed by operators of liquid pipelines for handling pipeline operations, maintenance and, emergencies and for training, communications and public education. In response to six petitions for reconsideration, DOT has made certain changes to that final rule. Among these changes are: (1) to provide for the use of fail safe equipment in lieu of moniforing pipeline operations from attended locations, (2) to more clearly define those facilities which would require procedures for immediate response by the carrier in event of malfunction, and (3) to permit conversion of certain pipelines to service under Part 195 which-were not designed and constructed in accordance with this Part.
