## operations

- Enbridge reports liquid in the Line 5 excavation down to about 140 barrels as the September 6-8 restart window opens; no restart confirmation posted through the weekend. [1]
  - Analysis: The cleanup phase is ending; the open question shifts from vapor removal to whether PHMSA's hold on the site outlasts the restart.
- PHMSA's reopened comment window on the 13 advisory-committee modernization NPRMs closed September 4; Pipeline Safety Trust and EDF had asked for 30 more days and received 4. [2]
  - Analysis: A compressed clock on 13 concurrent rule changes favors trade groups with standing comment machinery over safety advocates; late comments are considered only to the extent practicable.

## investments

- ONEOK agreed August 30 to acquire Brazos Midstream's Permian Midland Basin gathering and processing assets for $4.425 billion, backed by a $9 billion Apollo minority equity investment; the equity closes in the first half of September, the acquisition in Q4. [3]
  - Analysis: Midland gas processing under ONEOK roughly doubles to about 2.3 Bcf/d including plants under construction; gathering-system integrity programs and incident exposure consolidate with it.

## technology

- Inside PHMSA's 13-rule modernization slate now past comment: a proposal to make right-of-way patrol requirements technology neutral, allowing drones and satellites to satisfy patrol obligations on gas and liquid lines (Docket PHMSA-2025-0118). [4]
  - Analysis: If finalized, aerial and satellite patrols move from supplement to compliance instrument, changing the buy case for remote sensing programs.
