This recommended practice (RP) covers the integrity management of hazardous liquid facilities. This RP provides guidance on:
— high-consequence area impact determinations;
— data integration;
— threat identifcation;
— risk assessment;
— inspection and reinspection;
— preventive and mitigative measures (P&MM);
— performance measures.
Facilities include terminal and pipeline station piping systems within terminal and pipeline facility boundaries and includes of-plot piping. Of-plot piping includes, but is not limited to, piping between facilities, piping that comes from or goes to a refnery or other type facility, or piping that may cross a road, ditch, or other property outside the confnes of a terminal facility. This RP covers the integrity management of all pressure-containing components directly used in the transport or storage of hazardous liquids within a liquids pipeline facility.
Piping for transportation of hazardous liquids, such as but not limited to crude oil, highly volatile liquids (HVLs),
gasoline, diesel, biofuels, lubricating oils, jet fuel, and aviation fuel are covered by the scope of this document.
This RP does not apply to refnery piping, sanitary waste piping, cast iron piping, or nonmetallic gravity fow piping systems. Tanks are considered and reviewed as part of the high-consequence area analysis and risk assessment. For guidance on the inspection and maintenance of tanks, refer to API 653 or API Std 261 0 [1 ] .
This RP builds on concepts developed in API RP 11 60, Managing System Integrity for Hazardous Liquid Pipelines.
Additional guidance is available in documents such as API 570 and API Std 261 0.
