reports to the Director pursuant to Corrective Measure 14 within 90 and 180 days
of completing the tool run.
(D) Respondent must perform a comparative strain analysis utilizing the tool
run data attained in Corrective Measures 19(B)-(C) to more accurately identify
potential areas of strain that may warrant further investigation. If any segments of
pipe are determined to be subject to excessive external stress, Respondent must
submit an RWP to the Director pursuant to Corrective Measure 15 for remediating
those segments. Respondent must consult with appropriate subject matter experts
and determine appropriate acceptable action levels for geohazards and other
conditions. In the absence of an acceptable action level determination as agreed
upon with the Director, the default values of two (2) percent strain for pipe and 0.5
percent strain for girth welds will be utilized. After appropriate determination of
the action levels, Respondent shall remediate any identified locations above the
specified thresholds as required by the applicable provisions in Subpart M or
Subpart O of Part 192. Any other conditions discovered during the tool runs
performed under Corrective Measures 19(A)-(C) that are actionable under Part 192
must be remediated as contemplated by the applicable code sections and included
in the RWP submitted to the Director pursuant to Corrective Measure 15.
2 The requirements specified in the text of Subpart M or Subpart O of Part 192 on the Effective Date apply under the
terms of this paragraph 19, regardless of whether their general applicability to the pipeline industry is presently
effective (e.g., PHMSA’s enforcement discretion until February 2024 as to certain Part 192 requirements does not

APPENDIX I:
DCVG PLAN
Condition 16 of the Agreement requires Respondent to conduct alternating current voltage gradient
(ACVG), direct current voltage gradient (DCVG), or other comparable inspection, testing, or
surveys capable of locating and assessing pipeline coating conditions indicative of potential
corrosion threats or anomalies, on certain pipeline segments prior to commissioning. Respondent
has developed a plan for conducting the surveys required by Condition 16, and that plan will
require Respondent to conduct a minimum of 14 DCVG surveys of varying lengths. Respondent
considered the following technical, logistical, and personnel safety considerations in selecting the
DCVG survey segments:
• Survey segments of adequate length to provide meaningful data that can be analyzed
quickly to determine where excavations for further investigations are required.
• Survey segments that predominantly coincide with the existing construction Spread
breaks. These Spread breaks also coincide with changes in the topography and similar
geologic conditions.
• Survey segment breaks where large installation gaps existed prior to 2023 construction
activities or at test segment break points. These break points ensure that additional welding
will not interfere with the testing or results conducted in those segments.
• Survey segments based on the availability of permanent cathodic protection groundbeds to
use as the anode source during testing.
• Survey sections based on the schedule for completing continuous pipe sections to minimize
the number of excavations that need to occur during winter months.
Respondent may divide the 14 survey segments described in Table 1 below into smaller sections
to facilitate coordination with other ongoing construction activities. If that occurs, Respondent
will still conduct the minimum number of excavations required under Condition 16 of the Consent
Agreement.

NOTICE OF PROPOSED SAFETY ORDER
Background and Purpose
This Notice of Proposed Safety Order (NOPSO or Notice) is being issued by the Pipeline and
Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS), under the
authority of 49 U.S.C. § 60117. Pursuant to § 60117, PHMSA has initiated an investigation and
on-site inspections of the safety of Equitrans Midstream Corporation’s (ETRN) Mountain Valley
Pipeline, LLC in West Virginia and Virginia.
PHMSA’s ongoing investigation indicates that conditions may exist on ETRN’s Mountain Valley
Pipeline (MVP) facilities that pose a pipeline integrity risk to public safety, property, or the
environment. The conditions potentially exist on the MVP system and may present immediate risk
if the pipeline is commissioned without remediation.
1 Pursuant to 49 U.S.C. § 60117(m), PHMSA
is issuing this Notice to notify you of the preliminary findings of the investigation and propose you
take measures to ensure that the public, property, and the environment are protected from the
potential risks.
Preliminary Findings
A. General Preliminary Findings
• The MVP construction project encompasses the proposed and partially constructed MVP
interstate natural gas transmission system in its entirety, which will be comprised of
approximately 303 miles of 42-inch diameter coated steel pipe (Affected Facility). The
Affected Facility traverses the states of West Virginia and Virginia, commencing at mile
