WARNING LETTER
VIA ELECTRONIC MAIL TO: dan Mcvey@theenergycoop.com
May 20, 2025
Mr. Dan McVey
Vice President and Chief Operating Officer
NGO Transmission, Incorporated
1500 Grandville Road
Newark, Ohio 43058
CPF 1-2025-011-WL
Dear Mr. McVey:
From June 24 through June 27, 2024, representatives of the Pipeline and Hazardous Materials
Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code (U.S.C.),
inspected NGO Transmission, Inc. (NGO)’s underground natural gas storage records and
procedures for the Perry, Muskie, and Zane storage fields in Perry County and Muskingum County,
Ohio.
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. § 192.12 Underground natural gas storage facilities.
(a) …
(d) Integrity management program
(1) …
(4) Integrity management procedures and recordkeeping. Each
UNGSF operator must establish and follow written procedures to carry
out its integrity management program under API RP 1171
(incorporated by reference, see § 192.7), section 8 ("Risk Management
for Gas Storage Operations"), and this paragraph (d). The operator
must also maintain, for the useful life of the UNGSF, records that
demonstrate compliance with the requirements of this paragraph (d).



This includes records developed and used in support of any
identification, calculation, amendment, modification, justification,
deviation, and determination made, and any action taken to implement
and evaluate any integrity management program element.
NGO failed to maintain, for the useful life of the UNGSF, records that demonstrate compliance
with the requirements of § 192.12(d). Specifically, NGO failed to maintain records of its risk
management effectiveness reviews required under American Petroleum Institute Recommended
Practice 1171 (API RP 1171), Section 8.7.1 (Section 8.7.1).
Section 8.7.1 states in part that “[t]he operator shall assess the effectiveness of risk monitoring and
risk management programs and maintain a continual review and improvement cycle in risk
management activities to provide functional integrity of the storage operation. The interval of
review and reassessment should be short enough to identify operational and monitoring trends and
measure the effectiveness of P&M measures, but long enough that the data and information that
can be brought into the analysis are meaningful.”
During the inspection, PHMSA requested records of the Risk Management effectiveness reviews
conducted pursuant to Section 8.7.1. NGO stated that the reviews were not documented.
Therefore, NGO failed to maintain records demonstrating compliance with § 192.12(d) as required
by § 192.12(d)(4).
2. § 192.12 Underground natural gas storage facilities.
(a) …
(d) Integrity management program
(1) …
(4) Integrity management procedures and recordkeeping. Each
UNGSF operator must establish and follow written procedures to carry
out its integrity management program under API RP 1171
(incorporated by reference, see § 192.7), section 8 ("Risk Management
for Gas Storage Operations"), and this paragraph (d). The operator
must also maintain, for the useful life of the UNGSF, records that
demonstrate compliance with the requirements of this paragraph (d).
This includes records developed and used in support of any
identification, calculation, amendment, modification, justification,
deviation, and determination made, and any action taken to implement
and evaluate any integrity management program element.
NGO failed to maintain, for the useful life of the UNGSF, records that demonstrate compliance
with the requirements of § 192.12(d). Specifically, NGO failed to maintain records of its risk
assessment records and reviews for 2021 and 2022 that are required pursuant to API RP 1171,
Section 8.5.2 (Section 8.5.2).



Section 8.5.2 states in part that “[t]he operator shall review the results of the risk assessment to
determine whether the risk assessment, resulting prioritization, or ranking represents its facilities
and characterizes the risks. Review may be performed by personnel familiar with storage
operations, risk management, and methods of analyzing risk and results.”
During the inspection, PHMSA requested the records tracking the risk assessments and reviews
conducted pursuant to Section 8.5.2. NGO stated that the Risk Assessment files for 2021 and 2022
did not save in their database system.
Therefore, NGO failed to maintain records demonstrating compliance with § 192.12(d) as required
by § 192.12(d)(4).
Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to exceed
$266,015 per violation per day the violation persists, up to a maximum of $2,660,135 for a related
series of violations. For violation occurring on or after January 6, 2023 and before December 28,
2023, the maximum penalty may not exceed $257,664 per violation per day the violation persists,
up to a maximum of $2,576,627 for a related series of violations. For violation occurring on or
after March 21, 2022 and before January 6, 2023, the maximum penalty may not exceed $239,142
per violation per day the violation persists, up to a maximum of $2,391,142 for a related series of
violations. For violation occurring on or after May 3, 2021 and before March 21, 2022, the
maximum penalty may not exceed $225,134 per violation per day the violation persists, up to a
maximum of $2,251,334 for a related series of violations. For violation occurring on or after
January 11, 2021 and before May 3, 2021, the maximum penalty may not exceed $222,504 per
violation per day the violation persists, up to a maximum of $2,225,034 for a related series of
violations. For violation occurring on or after July 31, 2019 and before January 11, 2021, the
maximum penalty may not 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.
