WARNING LETTER
OVERNIGHT EXPRESS DELIVERY

Mr. Kenneth Foyil
Vice President Operations
Cadeville Gas Storage, LLC
598 Minden Street, Suite A
Ruston, Louisiana 71270
CPF 1-2022-007-WL
Dear Mr. Foyil:
From October 4, 2022, through October 6, 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 Cadeville Gas Storage, LLC’s (CGS) Cadeville Gas Storage Field in Ouachita County,
Louisiana.
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 inspected and the probable
violation is:
1. § 192.12 Underground natural gas storage facilities.
(a) …
(c) Procedural manuals. Each operator of a UNGSF must prepare and
follow for each facility one or more manuals of written procedures for
conducting operations, maintenance, and emergency preparedness and
response activities under paragraphs (a) and (b) of this section. Each
operator must keep records necessary to administer such procedures and
review and update these manuals at intervals not exceeding 15 months, but
at least once each calendar year. Each operator must keep the appropriate
parts of these manuals accessible at locations where UNGSF work is being
performed. Each operator must have written procedures in place before
commencing operations or beginning an activity not yet implemented.
CGS failed to meet the requirements of § 192.12(c). Specifically, CGS failed to review and update its
Operations and Maintenance (O&M) manuals and Emergency Response Plan (ERP) at intervals not to



exceed 15 months, but at least each calendar year.
During the inspection, PHMSA found that CGS’s records indicated its UNGS O&M manuals and ERP
were reviewed and updated on 5/21/2021 and 09/21/2022, exceeding the 15-month interval
requirement by 1 month.
Therefore, CGS failed to meet the requirements of § 192.12(c) regarding the interval for reviewing and
updating its O&M and ERP manuals.
Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to 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. 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.

not to conduct additional enforcement action or penalty assessment proceedings at this time. We advise
