MRT is issuing a System Protection Warning (SPW) to inform its shippers that receipt nominations from:

·         STL Chain of Rocks (100007)

·         NGPL Madison (92136)

·         NGPL Shattuc (805588)

·         Trunkline Clay Co (12817)

·         Mo Gas Madison (91031)

to delivery points south of the Columbia Measurement Station may not be scheduled. In addition, receipts from the above referenced list may not exceed Market Area delivery consumption at points north of the Columbia Measurement Station.

If the Market Area supply is anticipated to exceed the total consumption north of the Columbia Measurement Station, MRT may schedule receipts down to match the delivered volume.  MRT expects impacts to Secondary Firm and Interruptible services during this time.

To avoid impacts, Secondary Firm and Interruptible shippers should nominate supply from points south of the Columbia Measurement Station. 

MRT will be monitoring the nominations on this system closely.  Nominations will be scheduled in accordance with MRT's Tariff.  This SPW will be updated as more information becomes available. 

If you have any questions concerning this SPW, please contact your Scheduling Representative.
