Previous Information Posted 11/27/25

Due to the potential for maximum utilization of northbound firm Main Line capacity causing a potential supply deficiency in the Market Zone, MRT is issuing a System Protection Warning (SPW) effective 9:00 a.m. Sunday, November 30^th, 2025, and continuing until further notice.

 

During this time:

 

1)      MRT may not schedule any IT or AOR volumes for delivery north of Perryville.

 

2)      Firm volumes may be limited to their primary direction of flow within path on the system north of Perryville.

 

3)      MRT may not schedule volumes that result in a daily short position in either the Market or Field Zones.

 

4)      The use of imbalance positions may not be scheduled.

 

5)      Pool transfers will not be permitted from MRT’s Field Zone to its Market Zone.

 

6)      The availability of non-ratable flows for shippers who do not hold both northbound Main Line and Storage capacity may be limited.

 

7)      Shippers with primary delivery points north of the Glendale Compressor station and a receipt point that utilizes South to North transportation, will be required to nominate and source all, or a portion of, their total nomination at primary receipt points and/or at available Market Zone supply locations, not to exceed applicable maximum receipt point quantities in order to support their primary deliveries.

 

8)      Shippers whose firm transportation contracts have Texas Gas Boardwalk (“Boardwalk”) and/or EGT Olyphant (“Olyphant”) and/or Noark listed as primary receipt points, must schedule the full amount of their primary receipt point quantity at each of those points or, if the primary receipt point is Boardwalk and/or Olyphant, at an alternative Main Line receipt point that is north of the primary receipt point (Olyphant and/or Noark) if they desire to fully utilize their contract MDQ.  Shippers may elect to forego nominating their full primary receipt point quantity at any/all of these points, however, such Shipper’s maximum scheduled and confirmed contract quantity shall be limited to their contract MDQ less any primary receipt point quantity at Boardwalk and/or Olyphant and/or Noark that is not scheduled and confirmed.

 

Shippers whose deliveries are affected by any of the eight (8) conditions above are encouraged to source supply at their primary receipt points, MRT’s East Line, Madison Line, MoGas, or reduce applicable delivery volumes.

 

Failure to comply with this SPW may result in Shippers being issued an individual OFO.  Nominations will be confirmed and scheduled in accordance with MRT’s Tariff.

 

This SPW will be updated as more information becomes available.
