WARNING LETTER
VIA ELECTRONIC MAIL TO: jbenning@DuluthMN.gov
October 29, 2020
Jim Benning
Director
City of Duluth Public Works & Utilities
City Hall, Room 274
411 West First Street
Duluth, MN 55802
CPF 3-2020-1010W
Dear Mr. Benning:
Between August 6 and 8, 2019, a representative of the Pipeline and Hazardous Materials Safety
Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code (U.S.C.) inspected
the 10-inch natural gas transmission pipeline, which is operated and maintained by the City of
Duluth, and runs from the Great Lakes Gas transmission interconnect in Douglas County, WI to
the City of Duluth’s regulator station in St. Louis County, MN.
As a result of the inspection, it is alleged that you have committed a probable violation of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The item(s) inspected
and the probable violation(s) are:
1. §192.931 How may Confirmatory Direct Assessment (CDA) be used?
An operator using the confirmatory direct assessment (CDA) method as allowed in
§192.937 must have a plan that meets the requirements of this section and of
§§192.925 (ECDA) and §192.927 (ICDA).



(a)…
(b) External corrosion plan. An operator's CDA plan for identifying external
corrosion must comply with §192.925 with the following exceptions.
(1) The procedures for indirect examination may allow use of only one indirect
examination tool suitable for the application.
(2) The procedures for direct examination and remediation must provide that—
(i) All immediate action indications must be excavated for each ECDA region; and
(ii) At least one high risk indication that meets the criteria of scheduled action must
be excavated in each ECDA region.
The City of Duluth failed to comply with § 192.931 because its confirmatory direct assessment
(CDA) plan for external corrosion did not comply with the requirements in § 192.925. Section
192.925 delineates requirements for using the ECDA process. Specifically, § 192.925(b) states
that “[a]n operator that uses direct assessment to assess the threat of external corrosion must
follow the requirements in this section, in ASME/ANSI B31.8S (incorporated by reference, see §
192.7), section 6.4, and in NACE SP0502 (incorporated by reference, see § 192.7).” During the
inspection, the City of Duluth provided a 2017 CDA report that was prepared by its contractor
and identified multiple external corrosion direct assessment (ECDA) regions, which included
above grade piping at the regulator station in St. Louis County. However, NACE SP0502-2010
is only applicable to buried onshore ferrous pipeline systems. Therefore, any assessments
performed on above grade piping are not considered valid using ECDA.
Furthermore, the 2017 CDA report deemed any excavations to below grade pipe section were
unnecessary based on the results of the indirect inspection surveys. According to Sections 5.1.3
and 5.3.1.1 of NACE SP0502-2010 at least one excavation or direct examination is required.
Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to exceed
$218,647 per violation per day the violation persists, up to a maximum of $2,186,465 for a
related series of violations. For violation occurring on or after November 27, 2018 and before
July 31, 2019, the maximum penalty may not exceed $213,268 per violation per day, with a
maximum penalty not to exceed $2,132,679. For violation occurring on or after November 2,
2015 and before November 27, 2018, the maximum penalty may not exceed $209,002 per
violation per day, with a maximum penalty not to exceed $2,090,022. For violations occurring
prior to November 2, 2015, the maximum penalty may not exceed $200,000 per violation per
day, with a maximum penalty not to exceed $2,000,000 for a related series of violations. We
have reviewed the circumstances and supporting documents involved in this case, and have
decided not to conduct additional enforcement action or penalty assessment proceedings at this
time. We advise you to correct the item(s) identified in this letter. Failure to do so will result in
the City of Duluth being subject to additional enforcement action.
No reply to this letter is required. If you choose to reply, in your correspondence please refer to
CPF 3-2020-1010W. Be advised that all material you submit in response to this enforcement
action is subject to being made publicly available. If you believe that any portion of your
2



responsive material qualifies for confidential treatment under 5 U.S.C. 552(b), along with the
complete original document you must provide a second copy of the document with the portions
you believe qualify for confidential treatment redacted and an explanation of why you believe
the redacted information qualifies for confidential treatment under 5 U.S.C. 552(b).
Sincerely,
Gregory A. Ochs
Director, Central Region, OPS
