WARNING LETTER
VIA ELECTRONIC MAIL TO: rjstamour@marathonpetroleum.com
October 26, 2023
Mr. Rich St. Amour
President
Marathon Pipe Line LLC
539 South Main Street
Findlay, OH 45840
CPF 5-2023-056-WL
Dear Mr. St. Amour:
From May 31 through June 23, 2023, a representative of the Pipeline and Hazardous Materials
Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code (U.S.C.),
inspected Marathon Pipeline LLC’s (Marathon) crude oil and refined products pipelines in
Nikiski and Anchorage, Alaska.
As a result of the inspection, it is alleged that you have committed probable violations of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The items inspected
and the probable violations are:
1. § 195.452 Pipeline integrity management in high consequence areas.
(a) . . .
(g) What is an information analysis? In periodically evaluating the integrity of each
pipeline segment (see paragraph (j) of this section), an operator must analyze all
available information about the integrity of its entire pipeline and the consequences
of a possible failure along the pipeline. Operators must continue to comply with the
data integration elements specified in § 195.452(g) that were in effect on October 1,



2018, until October 1, 2022. Operators must begin to integrate all the data elements
specified in this section starting October 1, 2020, with all attributes integrated by
October 1, 2022. This analysis must:
(1) Integrate information and attributes about the pipeline that include, but are not
limited to:
(i) . . .
(viii) Data gathered through integrity assessments required under this section;
Marathon failed to integrate and analyze data gathered through their 2021 integrity assessments
for their Kenai Refinery to Anchorage refined products pipeline, as required. Specifically, in
2021, Marathon conducted an integrity assessment using a suite of in-line inspection (ILI) tools
(including a UT crack tool, a circumferential UT crack tool, a geometry (caliper) tool, a
corrosion assessment tool (MFL), and an inertial mapping tool). These integrity assessments
were completed between February and April 2021. During PHMSA’s 2023 inspection, Marathon
stated that it integrates and analyzes ILI assessment data through the process of preparing a Data
Integration Report. However, Marathon could not produce any records demonstrating it had
completed the Date Integration Report nor any other record of ILI data integration for their 2021
assessments as of the May 2023 inspection.
Therefore, Marathon failed to comply with § 195.452(g)(1)(viii) by not integrating and analyzing
its ILI data as required.
2. § 195.591 In-Line inspection of pipelines.
When conducting in-line inspection of pipelines required by this part, each operator
must comply with the requirements and recommendations of API Std 1163, Inline
Inspection Systems Qualification Standard; ANSI/ASNT ILI–PQ, Inline Inspection
Personnel Qualification and Certification; and NACE SP0102–2010, Inline Inspection
of Pipelines (incorporated by reference, see § 195.3). An in-line inspection may also
be conducted using tethered or remote control tools provided they generally comply
with those sections of NACE SP0102–2010 that are applicable.
Marathon failed to comply with API Std 1163 as required. Specifically, during inspection,
Marathon had not validated the results of their 2021 in-line inspections (ILI) of their Kenai
Refinery to Anchorage refined products pipeline. ILI data validation is a process required by API
Std 1163. Between February and April 2021, Marathon conducted an integrity assessment using
a suite of ILI tools (including a UT crack tool, a circumferential UT crack tool, a geometry
(caliper) tool, a corrosion assessment tool (MFL), and an inertial mapping tool). During the
2023 inspection, Marathon stated that its ILI validation process is completed and documented
through the process of preparing a Data Integration Report. However, Marathon could not
provide the completed Data Integration Report nor any other record of ILI validation for its 2021
assessments as of the May 2023 inspection.
Therefore, Marathon failed to comply with § 195.591 by not validating the results of its 2021 ILI
assessments as required per API Std 1163.
