6 Introduction Background The purpose of this API document is to provide Liquid and Gas Pipeline Operators ( Operators ) with a guidance document to aid in the Pipeline and Right-of-Way (ROW) status and disposition. PHMSA has pipeline status classified in two stages of either active or idled. Historically, Pipeline Operators have been modifying their Company pipeline status to fit into additional statuses. The intent of this document is to clearly identify additional pipeline statuses used throughout industry to provide clarity and accuracy. The scope of this document does not include guidance necessary for easement determination. The instruction should only be used for pipeline safety matters. 1 Scope Pipeline Status Determination This document provides guidance for maintaining and executing the status of a Pipeline. This document provides the framework for pipeline maintenance and provides guidance on managing pipeline assets throughout their lifecycle. Additionally, this establishes: Pipeline, equipment, ROW, and operations maintenance expectations for all pipeline stages Documentation requirements Pipeline Maintenance guidance by status type For purposes of this document, the word pipeline refers to transmission and regulated gathering pipelines and pipeline systems, both offshore and onshore, although the principles may be applied to non-regulated gathering and flow lines. Additional informative appendices discuss legacy out-of-service (quondam) assets, offshore pipeline abandonment, records retention practices, and cleaning and purging of pipelines. Stage Pipeline ROW Regulated by the Office of Pipeline Safety (OPS) a 0 Pre-Commissioned Limited maintenance for preservation Maintained Limited 1 Active / In-service Maintained normal operations. Includes zero movement conditions with natural gas or hazardous liquid in the line. Maintained Yes 2 Idle b Shutdown, purged of its contents, pipeline isolated and equipment maintained, except where modified by Section 6 Maintained Yes c Systems or segments in stages 3 and 4 cannot be returned to service until requirements of applicable regulations and company documents are fulfilled.

7 3 Decommissioned No line pipe maintenance Modified ROW maintenance Limited 4 Abandoned Left in situ or removed Released to owner No a in the United States b piping in this stage is shown as Idle in the NPMS c in the US all 49 CFR rules apply 2 Abbreviations Table 1 Pipeline Status Overview For the purposes of this document, the following abbreviations apply. AOC API CFR DOT FAQ HQ NDT OPID OPS PARC PHMSA ROW abnormal operating conditions American Petroleum Institute Code of Federal Regulations Department of Transportation frequently asked question headquarters nondestructive testing Operator identification Office of Pipeline Safety Pipeline Abandonment Research Council Pipeline and Hazardous Materials Safety Administration Right-of-Way 3 Guidance for Developing a Written Program 3.1 Roles and Responsibilities Operators should define roles and responsibilities for the administration, management, and consistent implementation of the Pipeline Status program. Clear responsibilities for implementing the program should be established and communicated to affected individuals. Responsibilities associated with the Pipeline Status Program may include but are not limited to the following: Central management and oversight; Status and Status Change Approval; Management of System Integrity; Management of Right-of-Way; Management of equipment; 3.2 Program Improvement (Management System overview?) General While not specifically required by regulation, an Operator may consider developing processes for periodic review of the written program and auditing program implementation. Operators should determine the process for incorporating program improvements based on the findings.

8 3.2.2 Written Program Review The purpose of a periodic review of the written program is to insure that it meets current regulatory compliance and any additional needs of the Operator. The Operator has the flexibility to structure the review as formally or informally as deemed necessary and should document the results and identify appropriate modifications, if any Internal Audit The purpose of an internal audit is to assure the program is being implemented as written. The Operator has the flexibility to structure the audit as formally or informally as deemed necessary and should document the results of the audit and identify appropriate modifications, if any. 4 Stage 0: Pre-Commissioned Stage Pipeline ROW Regulated by the Office of Pipeline Safety (OPS) a 0 Precommissioned Limited maintenance for preservation Maintained Limited a In the US 4.1 General Table 2 Pre-commissioned Pipeline Status Considered post construction, prior to normal operations; the pipeline does not contain hazardous liquid or gas. All appropriate regulations are applicable 4.2 Documentation Document preservation plan and other appropriate construction documents. NOTE API RP 1177 provides considerations for appropriate construction quality management documents. 5 Stage 1: In Service Stage Pipeline ROW Regulated by the Office of Pipeline Safety (OPS) a 1 Active / In Service Maintained - normal operations. Includes zero movement conditions with natural gas or hazardous liquid in the line. Maintained Yes a In the US Table 3 Active / In-service Pipeline Status 5.1 General Considered normal operations; the pipeline contains hazardous liquid or gas and is operational Includes zero movement conditions with hazardous liquid or gas in the line Pipeline may be out of service for repairs or inspection on a temporary basis

9 All appropriate regulations are applicable All appropriate Integrity Management Plan requirements are applied Reference appropriate industry standards 5.2 Documentation For pipelines with zero movement conditions, some reporting may be required. Consider precautions against internal corrosion for lines with no movement for greater than 6 months Maintain appropriate documents per the jurisdiction for in service pipelines Mergers and Acquisitions add additional information into this sections Documentation requirements to PHMSA 6 Stage 3 Idle Stage Pipeline ROW Regulated by the Office of Pipeline Safety (OPS) a 3 Idle b Shutdown, purged of its contents, pipeline isolated, and equipment maintained, except where modified by this section ROW maintained for future use Yes c a in the United States b piping in this stage is shown as Idle in the NPMS c in the US all 49 CFR rules apply 6.1 Table 4 Idle Pipeline StatusGeneral Pipeline has been shut down, physically isolated from other in service lines, connections to all sources of the hazardous liquid or gas are sealed (cut and either capped or blinded), system purged of its contents, and removed from service. Pipeline, equipment and ROW are maintained for future use. Break-out tanks are purged of hazardous liquids Break-out tanks are considered in service and subject to all tank program requirements until purging is complete. etc.) Removal of pipeline components is acceptable (i.e. Motor Operators, electrical components, Line is purged with an inert material, such as nitrogen. Line is cleaned based on the operators procedures Line is blanketed with the appropriate media and pressure is maintained All appropriate maintenance activities are applicable Examples of maintenance activities that may be suspended include: Overpressure and overfill safety devices Valve inspections

10 Control Room Management Assessments required in IMP (ILI and hydro) Leak detection Break-out tank inspections Add technical justification on why the above aren t needed. NOTE Local regulation may supersede guidance given. 6.2 Documentation Document the cleaning plan and evidence it was completed successfully, which could include daily inspector logs, diagrams, and pictures Document the maintenance activities being deferred to be prepared if the line becomes active in the future. Maintain change documentation showing it is no longer in-service. 7 Stage 3 Decommissioned Stage Pipeline ROW Regulated by the Office of Pipeline Safety (OPS) a 3 -- Decommissioned Purged and isolated; No pipeline maintenance ROW maintenance may or not be performed No a in the United States 7.1 Table 5 Decommissioned Pipeline StatusGeneral Pipeline has been shut down, physically isolated from other in service lines, connections to all sources all of the hazardous liquid or gas are sealed (cut and either capped or blinded), system purged of its contents, sealed and removed from service. Regulation and easement requirements may supersede the guidance given here. NOTE Additionally: In the US, onshore pipelines which are no longer being maintained are considered abandoned by PHMSA. Line pipe maintenance is discontinued Pipeline is physically isolated from other in service pipelines. Connections to all sources of hazardous liquids or gas are isolated (cut and either capped or blinded). In the US, 49 CFR Part 191, 192, 192, 194, 195, or 199 are applicable until the line is purged of hazardous liquid or gas. Line is purged with an inert material, such as nitrogen depending on operator procedures, engineering judgment, and local regulation. Line is cleaned based on the operators procedures Line is filled with an appropriate media; pressure is not required to be maintained ROW maintenance (mowing, trimming, etc.) may or may not be performed One-call status is determined through risk analysis including reviews of local requirements

11 Markers should be left in place to identify the pipeline s location Above ground equipment is electrically and mechanically isolated and may be removed or demolished. Cathodic Protection programs are not required. Consideration should be given to road, railroad, levees, and water crossings for long-term impacts on physical assets and public safety 7.2 Documentation Document the cleaning plan and evidence it was completed successfully, which could include inspector logs, diagrams, and pictures Document ROW maintenance activities being performed or deferred. Maintain change documentation showing pipeline is no longer in-service. Documentation to support easement maintenance, such as landowner agreements and local requirements 8 Stage 4 Abandoned Stage Pipeline ROW Regulated by the Office of Pipeline Safety (OPS) a 4 -- Abandoned Left in situ or removed Released to owner No a in the United States 8.1 General Table 6 Abandoned Pipeline Status Pipeline has been shut down, physically isolated from other in service lines, connections to all sources all of the hazardous liquid or gas are isolated (cut and either capped or blinded), system purged of its contents, and removed from service. The operator no longer maintains easement rights on the route. Some or all of the pipeline may have been physically removed. Regulation and easement requirements may supersede the guidance given here. NOTE In the USA, onshore pipelines which are no longer being maintained are considered abandoned by PHMSA. Additionally; place. ROW and pipeline are not maintained and the ROW is released to the owner with the pipeline in Pipeline is physically isolated from other in service pipelines. Connections to all sources of hazardous liquids or gas are isolated (cut and either capped or blinded). In the US, 49 CFR Part 191, 192, 192, 194, 195, or 199 are applicable until the line is purged of hazardous liquid or gas. Line is purged with an inert material, such as nitrogen depending on operator procedures, engineering judgment, and local regulation.
