NOTICE OF AMENDMENT

G. Clark White
Executive Vice President Operations
Targa Downstream LLC
811 Louisiana Street Suite 2100
Houston TX 77002
CPF 4-2023-043-NOA
Dear Mr. White:
From February 22 to October 17, 2022, a representative of the Pipeline and Hazardous Materials
Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code (U.S.C.)
inspected Targa Downstream Resources, LLC’s (Targa) integrity management plan and
maintenance and operations procedures in Houston, Texas.
On the basis of the inspection, PHMSA has identified the apparent inadequacy found within
Targa’s integrity management plan 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.
§ 195.452 Pipeline integrity management in high consequence areas.
(a) . . . .
(h) What actions must an operator take to address integrity issues? -



(1) . . . .
(2) Discovery of condition. Discovery of a condition occurs when an
operator has adequate information to determine that a condition
presenting a potential threat to the integrity of the pipeline exists. An
operator must promptly, but no later than 180 days after an
assessment, obtain sufficient information about a condition to make
that determination, unless the operator can demonstrate the 180-day
interval is impracticable. If the operator believes that 180 days are
impracticable to make a determination about a condition found during
an assessment, the pipeline operator must notify PHMSA in accordance
with paragraph (m) of this section and provide an expected date when
adequate information will become available.
Targa’s integrity management plan was inadequate to assure safe operation of a pipeline facility
in accordance with § 195.402(c)(3). Specifically, Targa’s Integrity Management Program for
Liquids Transmission Pipeline (Rev: 4/1/2020) (IMP) failed to describe what adequate information
is needed to determine that a condition presenting a potential threat to the integrity of the pipeline
exists, as required by § 195.452(h)(2).
In Section 2.0 of its IMP, Targa failed to provide details on or define the adequate information
required to confirm discovery of a condition. This section copies the regulatory definition, with
no additional details. The plan must provide details on circumstances which may constitute
discovery of a condition.
Therefore, Targa’s written integrity management plan was inadequate to assure safe operation of
a pipeline facility in accordance with § 195.402(c)(3). Targa must revise its integrity management
plan to describe the adequate information needed to determine discovery of a condition in
accordance with § 195.452(h)(2).
