INSPECTION OFFICER ORDER NO. GC-001-2016

IN THE MATTER OF THE NATIONAL ENERGY BOARD ACT,
AN ORDER UNDER SECTION 51.1

Information not available

is employed by TransCanada PipeLines Limited (TCPL), and/or is a person conducting an excavation or construction on or near a facility located at all stations operated by TCPL.

On 18 and 19 July 2016, the undersigned National Energy Board Inspection Officer conducted an inspection of Kingston Meter Station.

The Inspection Officer has reasonable grounds to believe:

– The 2 mm minimum remaining wall thickness (MRWT) value for blasting the pipe referenced in TCPL’s Operating Procedure Pipeline Defect Assessment and Repair Procedures (ID # 003674615) poses a safety risk to all excavation personnel.

– TCPL’s response to NEB Inspectors’ Information Request (IR) question 2 to provide the rationale for relying on the value of 2 mm is unacceptable and is not in compliance with CSA Z662-15, clause 10.2.8.

– TCPL’s response to NEB Inspectors’ IR question 3 to include in every Technical Memorandum for Safe Dig Pressure Determination (Technical Memo) a minimum allowable wall thickness (MAWT) calculation is unacceptable and is not in compliance with CSA Z662-15, clause 10.2.8.

Based on the above mentioned, the inspection officer has reasonable grounds to believe that a hazard to the safety or security of the public, or employees of a company or a detriment to property or the environment is being or will be caused by the construction, operation, maintenance or abandonment of the pipeline, or excavation activity or construction of a facility as per 49(2)(a).

Therefore, Information not available is HEREBY ORDERED,

pursuant to sections 51.1 and 51.1(2) of the National Energy Board Act, to

 X  take measures specified below for guarding the safety or security of the public or employees or protecting property or the environment
 X  Suspend work until the hazard or detrimental situation has been remedied to the satisfaction of the inspection officer; or the order is stayed or rescinded by the Board

Specified Measures:

– TCPL shall not excavate any station piping until:

  1. TCPL provides documented evidence to the NEB Inspectors for review and approval that it has modified its Operating Procedure Pipeline Defect Assessment and Repair Procedures (ID # 003674615) to remove all references to the universal 2 mm MRWT value for blasting the pipe; and
  2. TCPL provides documented evidence to the NEB Inspectors for review and approval that it has included a MAWT calculation for each type of piping expected to be encountered considering all types of pipe grade, outside diameter (OD) and operating stress level in every Technical Memo.
