If a pipeline transports both gas and liquids (e.g., some off shore lines), does the hazardous liquid integrity management rule or the gas integrity management rule apply?
Lines that transport both liquids and gas must meet requirements applicable to both. In practice, this means that the more stringent requirements must be met. • FAQ-155. In several places, the rule requires that operators follow Appendices in ASME/ANSI B31.8S. The title of both Appendices A and B in the standard indicate they are non-mandatory. Must the requirements in these Appendices be followed verbatim? [05/05/2004]Answer: Where sections of consensus standards are incorporated by reference into a rule, those sections become binding requirements the same as if the language were repeated in the rule. Operators must follow the requirements in the Appendices of ASME/ANSI B31.8S when those Appendices, or sections thereof, are referenced in the rule, even though the standard indicates that the appendices are non-mandatory. • FAQ-159. What constitutes an “incident” of the kind for which operators implementing performance-based programs must evaluate for implications to their pipelines and
Lines that transport both liquids and gas must meet requirements applicable to both. In practice, this means that the more stringent requirements must be met. • Rule Basics [Top] [Bottom] FAQ-244. What is the OPS position with regard to implementation of “should” statements in industry standards that are invoked by the rule? [01/11/2006]Answer: OPS expects operators to implement “should” statements in industry standards that are invoked by the rule. Operators may choose to implement an alternative approach in meeting the recommendations of invoked standards. If this approach is taken, program requirements for the alternative approach must exist in IM Program documents and records must be generated by the alternative approach. The IM Program documents must also technically justify that the alternative approach provides an equivalent level of protection. If an operator chooses not to implement a “should” statement in an invoked standard, a sound technical basis for why it has not been im
