NOTICE OF AMENDMENT
VIA E-MAIL TO MR. CRAIG COLLINS
March 7, 2022
Mr. Craig Collins
Chief Operations Officer and
Senior Vice President
Western Midstream Partners, LP
9950 Woodloch Forest Dr., Suite 2800
The Woodlands, TX 77380
CPF 5-2022-018-NOA
Dear Mr. Collins:
From November 1 through 5, 2021, representatives of the Pipeline and Hazardous Materials
Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code, reviewed
the written control room management plan, procedures, and records of Western Midstream
Partners, LP (Western) in Platteville, Colorado.
On the basis of the inspection, PHMSA has identified apparent inadequacies found within
Western’s control room management procedures, as described below:
1. § 195.446 - Control room management.
(a) General. This section applies to each operator of a pipeline facility with a
controller working in a control room who monitors and controls all or part of a
pipeline facility through a SCADA system. Each operator must have and follow
written control room management procedures that implement the requirements of
this section. The procedures required by this section must be integrated, as
appropriate, with the operator’s written procedures required by § 195.402. …



Western’s written procedures were inadequate to assure safe operation of a pipeline facility.
Specifically, Western did not have and follow written control room management procedures that
implemented the requirements set forth in § 195.446. Pursuant to § 195.446(c)(2), each operator
must provide its controllers with the information, tools, processes and procedures necessary for
the controllers to carry out the roles and responsibilities the operator has defined by conducting a
point-to-point verification between SCADA displays and related field equipment when certain
conditions are met. In order to conduct a point-to-point verification, an operator must first define
and identify Safety Related Points (SRP) for the SCADA system.1 In practice, Western
Midstream maintains a list of Safety Related Points. However, the Western Midstream DOT
Pipeline Compliance Control Room Management Plan 4.0 (CRMP) does not indicate how
Western defines SRP nor does it include a written procedure that guides the selection of SRPs.
2. § 195.446 - Control room management.
(a)…
(e) Alarm management. Each operator using a SCADA system must have a written
alarm management plan to provide for effective controller response to alarms. An
operator's plan must include provisions to:
(1)…
(2) Identify at least once each calendar month points affecting safety that have been
taken off scan in the SCADA host, have had alarms inhibited, generated false alarms,
or that have had forced or manual values for periods of time exceeding that required
for associated maintenance or operating activities;…
Western’s written procedures were inadequate to assure safe operation of a pipeline facility.
Specifically, Western’s written alarm management plan, CRMP Section 5-Alarm Management,
did not provide for effective controller response to alarms because it failed to include procedures
for identifying points affecting safety that have been taken off scan in the SCADA host, have had
alarms inhibited, generated false alarms, or that have had forced or manual values for periods of
time exceeding that required for associated maintenance or operating activities once each
calendar month. During the inspection, the Western Midstream control room team was not able
to articulate how the review was conducted. Although the Western Midstream SCADA subject
matter expert articulated the process the SCADA group is expected to use to review and analyze
Alarms and other SCADA data, the CRMP does not contain a written procedure to conduct the
review.
Response to this Notice
This Notice is provided pursuant to 49 U.S.C. § 60108(a) and 49 C.F.R. § 190.206. Enclosed as
part of this Notice is a document entitled Response Options for Pipeline Operators in
Compliance Proceedings.

Closure Letter
Dear Mr. Collins:
From November 1 through 5, 2021, representatives from the Pipeline and Hazardous Materials
Safety Administration (PHMSA), pursuant to chapter 601 of 49 United States Code, conducted an
on-site pipeline safety inspection of the written control room management plan, procedures, and
records of Western Midstream Partners, LP (Western) in Platteville, Colorado. As a result of the
inspection, Western was issued a Notice of Amendment on March 7, 2022, which proposed
amendment of your procedures.
Western submitted its amended procedures on April 6, 2022. My staff 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,
Dustin Hubbard
Director, Western Region
