Notice Text

Columbia Gas Transmission, LLC (TCO) reminds customers of multiple pig runs on 10110 beginning Tuesday, April 1, 2025, through Thursday, April 3, 2025. The pigging will impact physical flow for certain hours in the gas day; therefore, TCO has been coordinating with the impacted operators for hourly assistance.  Based on current scheduled volume and coordinated operational assistance, TCO does not currently anticipate any reduction to firm nominations during the pigging; however, reductions to firm service through the Easton MA21 internal constraint could become necessary based on operating conditions. Please monitor the Daily Capacity Posting for updates.  Customers are encouraged to monitor the Construction & Maintenance Schedule and the Daily Capacity Posting for any non-firm adjustments as a result of the pigging.  Reservation charge credits (RCCs) will be determined per the process set forth in the General Terms and Conditions, Section 38 of TCO’s FERC Gas Tariff (Tariff).  However, TCO will only issue RCCs if TCO 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 average usage quantity less any scheduled quantities on the contract. By means of this notice, TCO is establishing which specific Gas Days will be included when determining a shipper’s 7-day average usage quantity pursuant to the provisions in the Tariff.  Please contact your Customer Services Representative with any questions.
