What must be included in notices informing PHMSA Pipeline Safety of inspection intervals that will be scheduled to extend beyond 5 years? When must they be submitted?
The rule clearly anticipates that most operators will adhere to the 5 year retest interval and that operators must make every effort to do so. Operators seeking to extend retest intervals will be expected to exercise and document their due diligence well in advance of the deadline. An operator extending an inspection interval beyond 5 years because the selected integrity assessment technology is not available must provide technical justification for why the intended assessment tool is most appropriate, explain why it cannot be available in time, and provide an estimate of when the assessment can be completed. The operator must also describe actions it is taking to evaluate the integrity of the pipe in the meantime. Notices of this kind of extension must be submitted to PHMSA Pipeline Safety no less than 180 days before the end of the 5-year interval. Operators using an ‘engineering basis’ to justify a re-assessment interval in excess of five years must provide a description of the tech
