Full Description

This recommended practice (RP) covers the integrity management of hazardous liquid pipeline facilities. This RP provides guidance on:

- high-consequence area impact determinations;
- data integration;
- threat identification;
- risk assessment;
- inspection and reinspection;
- preventive and mitigative measures (PMM);
- performance measures.

Facilities include terminal and pipeline station piping systems within terminal and pipeline facility boundaries and includes off-plot piping. Off-plot piping includes, but is not limited to, piping between facilities, piping that comes from or goes to a refinery or other type facility, or piping that may cross a road, ditch, or other property outside the confines 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 refinery piping, sanitary waste piping, cast iron piping, or nonmetallic gravity flow 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 Std 653 or API Std 2610.

This RP builds on concepts developed in API RP 1160, Managing System Integrity for Hazardous Liquid Pipelines, and outlines a Plan-Do-Check-Act cycle to carry out continuous assessment and improvement for a pipeline facility integrity program. This approach is considered Best in Class and is used to drive continuous operational improvement as in other API standards such as API RP 1173, Pipeline Safety Management Systems. Additional guidance is available in documents such as API 570, Piping Inspection Code: In-service Inspection, Rating, Repair, and Alteration of Piping Systems, and API Std 2610, Design, Construction, Operation, Maintenance, and Inspection of Terminal and Tank Facilities.
