Material Verification for Oil and Gas Clients Pipeline Integrity SolutionsOn October 1, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published amendments to 49 CFR Parts 191 and 192 in the Federal Register, issuing Part 1 of the Gas Transmission Mega-Rule or “Mega-Rule 1”.  In advance of Mega-Rule 1, SI developed field protocol and supported leading industry research institutes in validating in-situ Material Verification (MV) methodologies.  SI has continued to provide MV consulting support to our clients in response to Mega-Rule 1, ranging from program development and implementation to in-situ field data collection and analysis. 

Various sections of Mega-Rule 1 require operators of natural gas transmission pipelines to ensure adequate Traceable, Verifiable, and Complete (TV&C) material records or implement a MV Program to confirm specific pipeline attributes including diameter, wall thickness, seam type, and grade. Operators are now required to define sampling programs and perform destructive (laboratory) or non-destructive testing to capture this information and take additional actions when inconsistent results are identified until a confidence level of 95% is achieved. Opportunistic sampling per population is required until completion of testing of one excavation per mile (rounded up to the nearest whole number).

On October 1, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published amendments to 49 CFR Parts 191 and 192 in the Federal Register, issuing Part 1 of the Gas Transmission Mega-Rule.  This new regulation is commonly referred to as the Mega-Rule since it represents the most significant regulatory impact on gas transmission pipelines since the original Gas Transmission Integrity Management Program (TIMP) Regulation was issued in 2003

The original Notice of Proposed Rulemaking (NPRM) issued in April, 2016 was split into 3 Parts, with the first Part (Mega-Rule 1) including specific requirements to address congressional mandates in the 2012 Pipeline Safety Reauthorization, and other pipeline safety improvements, including:

  • Maximum Allowable Operating Pressure (MAOP) Reconfirmation (§192.624),
  • Material Verification (MV) (§192.607),
  • Engineering Critical Assessments for MAOP Reconfirmation (§192.632),
  • Analysis of Predicted Failure Pressure (§192.712),
  • Assessments Outside of High Consequence Areas (HCAs) (§192.710),
  • Additional Requirements to Evaluate Cyclic Fatigue (§192.917(e)(2)), and
  • Additional Analysis of Electric Resistance Welded (ERW) Seam Welds (§192.917(e)(4))

News & Views, Volume 49 | Digital Elevation Modeling: Support Pressure Tests Records and Reduce MAOP Reconfirmation Costs

By:  Scott Riccardella, Bruce Paskett, and Eric Elder

§ 192.624(a)(1) of the Mega-Rule 1 requires MAOP Reconfirmation for steel transmission pipe segments if records necessary to establish the MAOP in accordance with § 192.619(a)(2) (e.g. pressure test), including records required by § 192.517(a), are not traceable, verifiable, and complete and the pipeline is located in a high consequence area (HCA) or a Class 3 or Class 4 location.

Part 192, Section 192.517(a) requires that natural gas pipeline operators shall make and retain, for the useful life of the pipeline, a record of the following information for any Subpart J Pressure Test (PT):

  1. The operator’s name, the name of the operator’s employee responsible for making the test, and the name of any test company used,
  2. Test medium used,
  3. Test pressur,
  4. Test duration,Pressure recording charts, or other record of pressure readings.
  5. Elevation variations, whenever significant for the particular test, and
  6. Leaks and failures noted and their disposition.

A new program to help pipeline operators implement the Material Verification requirements in recently released pipeline regulation (Mega Rule)

On October 1, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published the long-awaited Mega-Rule  (Part 1).  One of the major new requirements identified in these amendments is when missing traceable, verifiable, and complete records, operators must implement a Material Verification (MV) (§192.607) program.  MV requires operators of natural gas transmission pipelines, to develop and implement procedures to verify the material properties and attributes of their pipeline system.  Included in the new regulation for MV are:

  • News & View, Volume 47 | Material Verification IntelligenceDevelop procedures for conducting destructive and non-destructive testing
  • Define population groupings and implement sampling programs
  • Implement and document laboratory testing
  • Complete in situ and non-destructive evaluations (NDE)
  • Expand sampling if inconsistent results based on NDE and laboratory testing
  • Document program results and preserve for the life of the pipeline asset

News & View, Volume 47 | Release of the First Safety of Gas Transmission Pipeline Regulation Mega-RuleOn October 1, 2019 the Pipeline and Hazardous Materials Safety Administration (PHMSA) published amendments to 49 CFR Parts 191 and 192 in the Federal Register issuing Part 1 of the Gas Transmission Mega-Rule1.  This new regulation is commonly referred to as the Mega-Rule, as it represents the most significant regulatory impact on gas transmission pipelines since the original Gas Transmission Integrity Management Program (TIMP) Regulation was issued in 2003.

General Overview
As a result of numerous transmission pipeline accidents in the late 1990’s, the congressional Pipeline Safety Improvement Act of 2002 required operators of natural gas transmission lines to create TIMP Plans to identify transmission lines in High Consequence Areas (HCAs), conduct risk assessments and manage the integrity of covered segments in HCAs  by conducting periodic integrity assessments. In 2010 through 2012, multiple incidents (Deep Water Horizon, San Bruno, California, Marshall, Michigan, Sissonville, WV) created a renewed focus on pipeline safety in Congress.

News & View, Volume 46 | Strategies, Projects and Technologies to Help Improve NDE Reliability in the Pipeline Industry

Pipeline operators face a multitude of threats, including service, environmental, or operational induced degradation to pipelines and related facilities. Non-Destructive Examination (NDE) is often used to characterize the nature and extent of this degradation. Thus, there is a critical need for reliable NDE as pipeline operators rely extensively on NDE as the basis for validating In-Line Inspection (ILI) results, determining fitness for service, and making repair and other operational decisions. Erroneous or inaccurate characterization of these defects can lead to unexpected leaks or failures, unnecessary and costly repairs, the establishment of an incorrect remaining life or re-assessment interval, and inaccurate (in)validation of ILI results.

Update on the Safety of Gas Transmission and Gathering Pipelines Rulemaking (known as the Mega-Rule)
Structural Integrity (SI) personnel have had significant involvement in the Gas Pipeline Advisory Group (GPAC) meetings focused on consideration of the proposed pipeline safety rule titled “Safety of Gas Transmission and Gathering Pipelines” (Notice of Proposed Rule Making April 8, 2016).  The meetings produced several recommendations to the Pipeline and Hazardous Materials Safety Administration (PHMSA) that are likely to be included in the Final Rule.  A key outcome of these meetings was that PHMSA has decided the Final Rule will be split into three sub-rule packages that will all be final rules to facilitate the rulemaking process:

  1. Maximum Allowable Operating Pressure (MAOP) reconfirmation, Material Verification, Expansion of Integrity Management Assessments Outside of High Consequence Areas (HCAs) and other related issues,
  2. Repair Criteria, Inspections Following Extreme Weather Events, Corrosion Control improvements, Management of Change; and
  3. Expansion of Part 192 regulations to include additional Gas Gathering Lines.
