[Docket No. PHMSA-2008-0301]

Editor’s note: WARNING! This is a lengthy article, for which I apologize. However, the standards that are incorporated into the pipeline safety regulations are very important, and extensive. This article just gives the highlights of what is changing. Even the highlights are exhausting! As usual, if you have questions about how any of these standards apply to your operations, we’d be glad to help.

PHMSA is proposing to eliminate the use of the previous editions of API Specification 5L “Specification for Line Pipe” and API 1104 “Welding of Pipelines and Related Facilities” and to adopt only the latest (2007) edition of those standards. The April 14, 2009 Direct Final Rule on that subject allowed either the 2007 or the earlier editions of those standards to be used.

PHMSA is proposing to incorporate only specific sections of NFPA 59A, Standard for the Production, Storage, and Handling of Liquefied Natural Gas (LNG) (2006 edition). Except for the specified sections in the 2006 edition, PHMSA proposes to continue to reference NFPA 59A (2001).

Standards not proposed to be incorporated by reference at this time are:

  • ASTM D638; Standard Test Method for Tensile Properties of Plastics (2008 edition)
  • ASTM D2513; Standard Specification for Thermoplastic Gas Pressure Pipe, Tubing and Fittings (2007 edition)
  • ASTM D2517; Standard Specification for Reinforced Epoxy Resin Gas Pressure Pipe and Fittings (2006)
  • ASTM F1055; Standard Specification for Electrofusion-Type Polyethylene Fittings for Outside Diameter Controller Polyethylene Pipe and Tubing (2006)
  • NFPA 58; Liquefied Petroleum Gas Code (LP-Gas Code) (2008 edition)
  • NFPA 59; Utility LP-Gas Plant Code (2008 edition)

PHMSA also proposes to revise the pipeline safety regulations to make non-substantive edits, update contact information, and provide clarification as specified in the following summary:

PHMSA is proposing to revise paragraph (c) in § 192.11 to require that Part 192 prevails if there is a conflict between Part 192 and NFPA 58 or 59.

PHMSA proposes to revise section 192.711 to clarify that the repair times for pipelines covered by § 192.711 pertained only to nonintegrity management repairs.

PHMSA is proposing to revise paragraphs (d) and (e) of Section 192.145 to use the same language as ANSI/ASME B31.8, paragraph 831.11(c) in referring to shell components. Proposed revisions to paragraph (d) will clarify the elements of a “shell component.” The proposed revisions will clarify the intent of § 192.145(d) and (e) regarding the design requirements for pressure containing parts of valves used in compressor stations. OPS has several interpretations, PI-75-057 and PI-71-014, stating that the plug or ball is not a pressure containing part. It is OPS’s intent to permit the use of cast iron plugs or balls in combination with steel shell components. In paragraph (e), PHMSA is proposing to clarify that cast iron, malleable iron, or ductile iron may be used in the valve ball or plug. These materials may not be used in the pressure holding shell components (body, bonnet, cover, or end flange).

PHMSA proposes to move the definitions “active corrosion”, “electrical survey” and “pipeline environment” from § 192.465(e) to § 192.3. This proposed revision will provide a broader applicability of these terms to Part 192 because these terms are also found in Part 192, Subparts I and O.

PHMSA proposes to clarify requirements for MAOP uprating in § 192.557(c) by including the location factor requirements in § 192.619(a)(2).

PHMSA is proposing to revise Section 193.2101 to incorporate by reference sections from the 2006 edition of NFPA59A pertaining to the seismic design of stationary LNG storage tanks. Other sections from the 2001 edition of NFPA 59A would continue to be incorporated by reference as designated in 193.2013. NFPA 59A (2006) incorporates by reference the 1990 edition of API 620 but PHMSA proposes to incorporate by reference the most recent version, API 620 (2008), for seismic design.

PHMSA is proposing to clarify the language in § 193.2321(a) and to use the broader terminology for non-destructive testing. PHMSA also proposes to revise 193.2321(b) to add new requirements in accordance with NFPA 59A’s 2006 edition for the ultrasonic examination of LNG tank welds for storage tanks with an internal design pressure at or below 15 psig.

PHMSA is proposing to revise Section 195.307 paragraph (c) to reflect revised section numbering regarding pneumatic testing from 5.3 to 5.2 of API Standard 650.

PHMSA is proposing to revise Section 195.401 to clarify that the requirement to repair a condition within a reasonable time period (unless an immediate hazard) only applies to conditions on pipelines not covered by § 195.452.

PHMSA is proposing to revise Section 195.432 paragraph (b) to eliminate the reference to section 4 in API Standard 653. All sections in API Standard 653 relating to inspection of in-service atmospheric and low-pressure steel aboveground breakout tanks are incorporated by reference.

PHMSA is proposing to revise Section 195.452 paragraph (h)(4)(i) to reflect new section numbering as specified in the updated ANSI/ASME B31.4. The referenced section would be changed from “451.7” to “451.6.2.2 (b)”.

Submit comments on the subject of this proposed rule on or before September 21, 2009 to http://www.regulations.gov and reference Docket No. PHMSA-2008-0301.

Standard Operating Procedure Updates

RCP has developed standard operating procedures for hundreds of pipeline operators ranging from gas transmission, hazardous liquids, gas distribution, reservoir and salt dome gas storage facilities, oil terminals, regulated onshore gathering and offshore oil & gas facilities. Our procedure development process goes well beyond the typical cookie-cutter generic templates that you can buy off the shelf. We have a strong track record with successful PHMSA and state inspection performance – failure is not an option. Our procedure development process integrates with the daily operating processes that your personnel and contractors currently follow. When complete, you will have a comprehensive set of procedures that are easy to manage and comply with federal and state regulatory requirements. For more information, contact Jessica Roger.
