AGT Planned Outage Schedule -- Update


Notice Text:

AGT Planned Outages

Below is a list of major outages known to date that will affect capacity or that impact major receipt/delivery areas on the Algonquin Gas Transmission (AGT) system. Due to unforeseen delays or scheduling conflicts, the dates of the outages listed below are subject to change. In addition, this schedule is not a complete list of all outages that will occur this outage season, and we reserve the right to update this list to reflect additional major outages when the timing of such major outages can be reasonably forecasted. Any changes to the list below will be posted at the earliest practical date. Furthermore, when operationally feasible, AGT will coordinate with upstream and downstream point operators as necessary, to help minimize the operational impact of outages.Parties are urged to monitor these posting to access the most current information.

Mainline Outages:

*Stony Point to Southeast:

May 24, 2019 - TBD

Cleaning Tool Date: Complete

In-Line Tool Date: Complete

Tool Run Results/ Potential Repairs: In Progress

Enhanced Survey Analysis Results/ Potential Repairs: TBD, 2020

As part of AGT's comprehensive integrity assessment of its pipeline system, AGT will be conducting detailed investigations on its 26" Main Line between its Stony Point and Southeast compressor stations.As a result of these investigations, AGT will be adjusting its operating pressure on the 26" Main Line to accommodate these investigations.  

AGT has determined that the current pressure restriction will remain through the winter until AGT can complete its assessments and appropriately remediate identified anomalies. AGT currently anticipates capacity impacts to be less than 40,000 Dth/d.

AGT will be conducting further detailed investigations on its 26" Main Line between Stony Point and Southeast compressor stations.Please refer to the Operational Capacity Matrix for a list of mainline capacities until these further detailed investigations are complete.

Depending on the results of the ILI Tool run and if further detailed investigations are required which result in a reduction of capacity; AGT will post on its EBB as soon as it is known.

26" Main Line - Lambertville Meter Station (00210 ALGONQUIN - LAMBERTVILLE, NJ) - to Mahwah Meter Station (MR 00201 MAHWAH BERGEN,NJ):

August 29, 2019 - TBD

Cleaning Tool Date: Complete

In-Line Tool Date: Complete

Tool Run Results/ Potential Repairs: July 28; July 28; July 28

Enhanced Survey Analysis Results/ Potential Repairs: TBD, 2020

As part of AGT's comprehensive integrity assessment of its pipeline system, AGT will be conducting further detailed investigations on its 26" Main Line between its Lambertville and Mahwah meter stations.As a result of these investigations, AGT will be adjusting its operating pressure on 26" Main Line between Lambertville and Mahwah meter stations to accommodate these investigations.  

As a result, during these investigations, AGT currently anticipates the capacity loss for receipts sourced west of Hanover with this pressure restriction to be approximately 60,000 Dth/d.

Additionally, during these pressure restrictions, AGT currently anticipates the capacity loss for receipts sourced east of Hanover with this pressure restriction to be approximately 47,000 Dth/d, which includes the TE/ AGT Lease Capacity.

Depending on the results of the ILI Tool run and if further detailed investigations are required which result in a reduction of capacity; AGT will post on its EBB as soon as it is known.
