Another notification, including reasons for repair delay, would be required when a pressure reduction exceeds 365 days. Also, PHMSA proposes to correct existing provisions for calculating a pressure reduction when making an immediate repair on a hazardous liquid pipeline. The proposed correction would allow operators to use another acceptable method to calculate reduced operating pressure when a specified formula is not applicable or results in a calculated pressure higher than operating pressure. Finally, PHMSA seeks the submittal of engineering analyses and technical data. These s
