Dear Mr. Girling:

Nova Gas Transmission Ltd. (NGTL)
Order SG-N081-001-2014
Request for Extension to Compliance deadlines

The National Energy Board (Board) is in receipt of NGTL’s request to extend the deadlines for compliance with Conditions 1 and 2 of Safety Order SG-N081-001-2014 (Order). NGTL states that it made this extension request in order to allow it and affected shippers additional time to assess the potential impacts that may be caused by the implementation of the Order, and for NGTL to advise the Board as required by Condition 3 of the Order.

The Board has considered NGTL’s request and has issued the attached Amending Order AO-001-SG-NO81-001-2014, the effect of which is to extend the compliance deadlines for Condition 1 to 24 April 2014, and for Condition 2 to 29 April 2014.

The Board acknowledges that NGTL has implemented a voluntary “pressure hold” to ensure that the 90 day high pressure for each of the pipelines identified in the Order will not be exceeded, with the exception of one pipeline that is currently undergoing an in-line inspection. The Board is satisfied that this pressure hold will provide an acceptable level of safety on these pipelines until the extended pressure restriction implementation deadlines. The Board expects NGTL to maintain this pressure hold until the pressure restrictions required by the Order are fully implemented by the deadlines outlined in the attached Amending Order.

Yours truly,

Sheri Young
Secretary of the Board
