NOTICE OF FORCE MAJEURE ANR Pipeline Company – Southwest Mainline Northbound

SEV 4/5Force Majeure0.186 Bcf/d10 days
Summary
ANR Pipeline has declared a Force Majeure event on the Southwest Mainline Northbound due to a pipeline leak between MLV 22-23 just downstream of Havensville Compressor Station in Pottawatomie County, Kansas. Effective 9/26 intraday with no incremental volumes scheduled, and from 9/27 through 10/5 the SWML Northbound (LOC #226630) is limited to 520 MMcf/d (0.520 Bcf/d), reducing capacity by 186 MMcf/d (0.186 Bcf/d). ANR anticipates Firm Primary curtailments of approximately 6% of current net nominations and 31% of contracted MDQ.
Trading note
ANR SWML Northbound force majeure removes 0.186 Bcf/d of northbound Gulf Coast-to-Midwest capacity through 10/5, with firm primary curtailments confirmed at up to 31% of contracted MDQ; expect bullish pressure at ANR ML 7 and Midwest delivery points versus Henry Hub, with the live SWML Northbound reading (0.553 Bcf/d scheduled against 0.615 Bcf/d operating capacity, 10.1% headroom) likely to tighten further as the restriction takes full effect.
Reroute potential
Moderate: TETCO, Trunkline (TGC), and Southern Natural (EGT) serve overlapping Gulf Coast-to-Midwest corridors and may absorb some displaced volumes, but with DEFIANCE WESTBOUND and LAGRANGE WESTBOUND already flagged OVER on the ANR system today, downstream congestion limits the effective reroute offset.

Notice Text
ANR Pipeline Company has identified a leak on the 0-100 line between MLV 22-23, just downstream of Havensville Compressor Station, located in Pottawatomie County, Kansas.

 

This is to notify all contracted parties of ANR Pipeline Company ("ANR") that pursuant to Section 6.7 of ANR's FERC Gas Tariff, ANR has declared a Force Majeure event in effect for natural gas transactions in the Southwest Mainline Northbound Area. As a result, capacity will be reduced as follows:

9/26 – (Intraday cycles) No incremental volumes will be scheduled

9/27 – 10/5 SWML Northbound (LOC #226630): 186 MMcf/d (leaving 520 MMcf/d)

ANR anticipates this posting may result in Firm Primary, Firm Secondary and Interruptible curtailments. Estimated impact to Firm Primary as follows:

        6% - Based on the Current Net Shipper Nominations

      31% - Based on the Current Contracted MDQ

Any reservation charge credits (RCCs) will be determined per the process set forth in the General Terms and Conditions, Section 6.36 of ANR’s FERC Gas Tariff (“Tariff”). However, ANR will only issue RCCs if ANR is unable to schedule or deliver primary firm nominated capacity as a result of the outage. In the event RCCs are issued as set forth in the Tariff, shippers will receive RCCs based on its 7-day Non-Force Majeure Average Usage Quantity, as defined in Section 6.36.2 of ANR’s Tariff, less any scheduled quantities on the contract. By means of this notice, ANR is establishing which specific Gas Days will be included when determining a shipper's 7-day Force Majeure Average Usage Quantity pursuant to Section 6.36.2(a) of the Tariff.
