Investigation and repairs progress; further pressure reduction will not affect natural gas delivery

Update #7

Media statement - May 14, 2024, 1:00 p.m. MDT

Last week the Canada Energy Regulator (CER) ordered a further pressure reduction for certain segments of the Grande Prairie Mainline on a precautionary basis and because NGTL GP confirmed that end users would not be seriously impacted. NGTL GP implemented the pressure reduction as required. Currently we do not have any service restrictions on the NGTL System and we do not anticipate any service interruption to natural gas delivery. The NGTL System's web-like pipeline structure provides many paths for gas transportation access.

We continue to communicate system performance to customers via our Daily Operating Plan and manage the NGTL System to meet day-to-day operations while minimizing impacts to customers. 

Update #6

• The investigation is ongoing and we continue to progress our activities with the regulators.
• A comprehensive integrity assessment has been completed on nearby assets and normal operations have resumed. The system has been reconfigured to accommodate appropriate interim operational measures and is now optimized to maximize the system capacity, limiting impacts to customers.
• The safety of people, communities and the environment continue to be our primary focus.
