Dear Mr. Pinto:
From April 16, 2024, to October 10, 2024, representatives of the Pipeline and Hazardous Materials
Safety Administration (PHMSA), Office of Pipeline Safety (OPS), pursuant to Chapter 601 of 49
United States Code (U.S.C.) inspected EnLink Processing Services, LLC’s (EnLink) procedures
for operations and maintenance in Dallas, Texas.
On August 20, 2025, PHMSA issued the Notice, CPF 4-2025-046-NOA, to EnLink proposing
amendments of its operations and maintenance procedures. EnLink provided its response to the
Notice, and submitted its amended procedures, on September 19, 2025.
PHMSA has reviewed the amended procedures, and it appears that the inadequacies outlined in
this Notice of Amendment have been corrected.
This letter is to inform you no further action is necessary and this case is now closed. Thank you
for your cooperation.
Sincerely,
Bryan Lethcoe
Director, Southwest Region, Office of Pipeline Safety

NOTICE OF AMENDMENT
VIA ELECTRONIC MAIL TO: walter.pinto@enlink.com
August 20, 2025
Walter Pinto
Executive Vice President
EnLink Processing Services, LLC
1722 Routh Street Suite 1300
Dallas, Texas 75201
CPF 4-2025-046-NOA
Dear Mr. Pinto:
From April 16 to October 10, 2024 of the on-site inspection, representatives of the Pipeline and
Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS), pursuant
to Chapter 601 of 49 United States Code (U.S.C.) inspected EnLink Processing Services, LLC’s
(EnLink) procedures for operations and maintenance in Dallas, Texas.
As a result of the inspection, PHMSA has identified the apparent inadequacies found within
EnLink’s procedures. The items inspected and the inadequacies are described below:
1. § 192.605 Procedural manual for operations, maintenance, and emergencies.
(a) . . . .
(b) Maintenance and normal operations. The manual required by
paragraph (a) of this section must include procedures for the
following, if applicable, to provide safety during maintenance and
operations.
(1) Operating, maintaining, and repairing the pipeline in
accordance with each of the requirements of this subpart and subpart
M of this part.
§ 192.710 Transmission lines: Assessments outside of high consequence areas.
(a) . . . .



(c) Assessment method. The initial assessments and the
reassessments required by paragraph (b) of this section must be
capable of identifying anomalies and defects associated with each of
the threats to which the pipeline segment is susceptible and must be
performed using one or more of the following methods:
(1) . . . .
(3) Spike hydrostatic pressure test. A spike hydrostatic pressure test
conducted in accordance with § 192.506. A spike hydrostatic pressure
test is appropriate for time-dependent threats such as stress corrosion
cracking; selective seam weld corrosion; manufacturing and related
defects, including defective pipe and pipe seams; and other forms of
defect or damage involving cracks or crack-like defects;
EnLink’s written procedures for conducting operations and maintenance activities were inadequate
to provide safety during maintenance and operations in accordance with § 192.605(b)(1).
Specifically, EnLink’s written manual failed to include procedures for conducting a spike
hydrostatic pressure test in accordance with § 192.710(c)(3).
EnLink’s procedure, Gas Integrity Management Plan (rev. 6.0; May 23, 2023) (IMP), table IMP
9-3 – Assessment Requirements for Transmission Pipelines in HCA’s, Note 4, provides for a spike
hydrostatic pressure test for time-dependent threats, selective seam weld corrosion, manufacturing
and related defects, and other forms of defect or damage involving cracks or crack-like defects. In
addition, EnLink’s procedure, Pressure Testing Standards (Rev. 7.0; May 22, 2018), tables 1
Onshore Gas Pipelines – Test Requirements, Note 1, provides for the performance of a spike
hydrostatic test if warranted, and requires a 15-minute test at 100 percent of specified minimum
yield strength (SMYS) or 1.5 MAOP per § 192.506. However, EnLink’s procedures do not
included detailed procedural steps for performing a spike hydrostatic test in accordance with the
requirements in § 192.506. .
Therefore, PHMSA proposes that EnLink revise its procedures to include specific instructions for
performing a spike hydrostatic pressure test in accordance with the requirements in § 192.506.
2. § 192.605 Procedural manual for operations, maintenance, and emergencies.
(a) . . . .
(b) Maintenance and normal operations. The manual required by
paragraph (a) of this section must include procedures for the
following, if applicable, to provide safety during maintenance and
operations.
(1) Operating, maintaining, and repairing the pipeline in
accordance with each of the requirements of this subpart and subpart
M of this part.
§ 192.710 Transmission lines: Assessments outside of high consequence areas.
(a) . . . .
(b) General -



(1) Initial assessment. An operator must perform initial
assessments in accordance with this section based on a risk-based
prioritization schedule and complete initial assessment for all
applicable pipeline segments no later than July 3, 2034, or as soon as
practicable but not to exceed 10 years after the pipeline segment first
meets the conditions of § 192.710(a) (e.g., due to a change in class
location or the area becomes a moderate consequence area),
whichever is later.
EnLink’s written procedures for conducting operations and maintenance activities were inadequate
to provide safety during maintenance and operations in accordance with § 192.605(b)(1).
Specifically, EnLink’s procedure, Non-HCA Assessments ENL-GOM-0098 (version 3.0; rev. May
23, 2023), failed to include a risk-based prioritization schedule, including any detailed instructions
or criteria for developing a risk-based prioritization schedule, for performing initial assessments
on segments outside of HCAs in accordance with § 192.710(b)(1).
1
Therefore, PHMSA proposes that EnLink revise its procedures to include detailed instructions for
developing a risk-based prioritization schedule for performing initial assessments on segments
subject to § 192.710(a), in accordance with § 192.710(b).
