Today, PHMSA and Equitrans Midstream Corporation (ETRN) entered into a Consent Agreement (hyperlink), requiring ETRN to take corrective measures following informal consultation with the operator. The actions outlined in the Consent Agreement include running tools capable of detecting damage to the pipe both before and after putting the pipe in the ground, obtaining third-party validation and witnessing coating testing/remediation activities, and developing a work plan that must be submitted to and approved by PHMSA.

On August 11, PHMSA issued a Notice of Proposed Safety Order (NOPSO) to Equitrans Midstream Corporation, proposing comprehensive assessments to identify and remediate any coating deficiencies, potential corrosion issues, and any potential land movement-related effects on previously installed pipe. The NOPSO aimed to ensure the pipe has effective coating, and that any potential corrosion or land movement-related issues are identified and addressed to protect communities adjacent to MVP, and the environment.  

Since 2017, PHMSA has spent over 229 days in the field conducting inspections on the MVP, ensuring that the pipe is constructed and installed in accordance with safety standards, including proper coating.
