Dear Mr. Green:
From April 12, 2021 to April 14, 2021, a representative of the Pipeline and Hazardous Materials
Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code inspected DCP
Midstreams’s (DCP) Integrity Management Procedures in Houston, Texas. As a result of the
inspection, DCP was issued a Notice of Amendment on December 22, 2021, which proposed
amendment of your Integrity Management Plan procedures.
DCP submitted its revised procedures on April 1, 2022. My staff reviewed the revised 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,
Mary L. McDaniel, P.E.
Director, Southwest Region

NOTICE OF AMENDMENT
ELECTRONIC MAIL - RETURN RECEIPT REQUESTED
December 22, 2021
George Green
Group Vice President and General Counsel
DCP Midstream
370 17th Street, Suite 2500
Denver, Colorado 80202
CPF 4-2021-070-NOA
Dear Mr. Green:
From April 12, 2021 through April 14, 2021, representatives of the Pipeline and Hazardous
Materials Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code,
inspected DCP Midstreams’s (DCP) Integrity Management Procedures in Houston, Texas.
On the basis of the inspection, PHMSA has identified the apparent inadequacies found within
DCP’s plans or procedures, as described below:
1. § 195.402 Procedural manual for operations, maintenance, and emergencies
(a) . . .
(c) Maintenance and normal operations. The manual required by paragraph (a) of this
section must include procedures for the following to provide safety during
maintenance and normal operations:
(1) . . .
(3) Operating, maintaining, and repairing the pipeline system in accordance with
each of the requirements of this subpart and subpart H of this part.
§ 195.416 Pipeline assessments.
(a) Scope. This section applies to onshore line pipe that can accommodate inspection
by means of in-line inspection tools and is not subject to the integrity management
requirements in § 195.452.



2. DCP’s Integrity Manual, Integrity Procedures, IP-002 Integrity Assessment Method
Selection Guide (December 2020) is inadequate because it does not address the assessment
of pipelines to be performed on those lines not currently subject to the requirements of
§ 195.452, as required by § 195.416. DCP’s written procedures for integrity assessment
do not address how the proper assessment method for those sections of line pipe that are
not subject to the requirements of § 195.452 will be determined, how DCP will handle
other technology, data analysis, or when discovery of conditions occurs.
DCP must amend its procedures to address assessments of pipelines to be performed that
are not subject to the requirements of § 195.452 in accordance with the requirements of
§ 195.416.
§ 195.452 Pipeline integrity management in high consequence areas.
(a) . . .
(f) What are the elements of an integrity management program? An integrity
management program begins with the initial framework. An operator must
continually change the program to reflect operating experience, conclusions drawn
from results of the integrity assessments, and other maintenance and surveillance
data, and evaluation of consequences of a failure on the high consequence area. An
operator must include, at minimum, each of the following elements in its written
integrity management program:
(1) . . .
(5) A continual process of assessment and evaluation to maintain a pipeline's
integrity (see paragraph (j) of this section);
(6) . . .
(j) What is a continual process of evaluation and assessment to maintain a pipeline's
integrity? -
(1) . . .
(5) Assessment methods. An operator must assess the integrity of the line pipe by
any of the following methods. The methods an operator selects to assess low
frequency electric resistance welded pipe or lap welded pipe susceptible to
longitudinal seam failure must be capable of assessing seam integrity and of
detecting corrosion and deformation anomalies.
(i) In-Line Inspection tool or tools capable of detecting corrosion and
deformation anomalies, including dents, gouges, and grooves. For pipeline
segments that are susceptible to cracks (pipe body and weld seams), an
operator must use an in-line inspection tool or tools capable of detecting crack
anomalies. When performing an assessment using an In-Line Inspection tool,
an operator must comply with § 195.591;
2



DCP’s Integrity Manual, Integrity Management Plan, Hazardous Liquids, Section
5 - Continual Assessment Process (February 2021) is inadequate because it does not
require the operator to use the proper in-line inspection tool (ILI) or tools capable of
detecting the suspected threat anomalies. Specifically, for crack detection, DCP’s Integrity
Manual, Integrity Management Plan, Hazardous Liquids, Section 5 - Continual
Assessment Process, 5.4.4 Integrity Assessment Method Selection states, "If there is a
suspicion that the segment is susceptible to cracks or ILI data has identified the presence
of crack-like features, the reassessment method selection should address cracks." Using
the term "should," does not mandate operator personnel to use the correct ILI tool or tools
capable of detecting crack anomalies.
DCP must revise its process to require the appropriate ILI tool or reassessment method to
be used when pipeline segments are susceptible to cracks.
