Notice Text:

Subject: Station 80-100 MLD Tool Runs (Job 1211799) 2026 Planned Outage and Maintenance Summary

Transco will be performing pipeline integrity assessments on Mainline D between Station 80 and Station 100 associated with Job#1211799 on its 2026 Planned Outage and Maintenance Summary. Operating Conditions resulting from this work may require Transco to restrict scheduled quantities for transportation priorities moving south to north through the location indicated below. Based on historical scheduled quantities, Transco does not anticipate impacts to primary firm services, and impacts to non-primary firm services are expected to be minimal. However, unforeseen issues including, but not limited to nominations, weather, or other factors impacting system operating conditions may result in more significant scheduling reductions than expected.

Pig Runs	Dates
Gauge/Cleaner Tool	June 9
MFL Tool	June 11

The location Throughput Section Boundary (“TSB”) listed below will be used to manage capacity availability during this planned work. An updated Market and Production Area constraint notice will include the TSB and the available quantity of all transportation priorities during the indicated period.
