FINAL ORDER
On September 30, 2015, pursuant to 49 U.S.C. § 60117, a representative of the Pipeline and
Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS),
reviewed certain information and records of Columbia Gulf Transmission, LLC (CGT or
Respondent), relating to an April 25, 2014 incident (Incident) on the company’s ML300 natural
gas pipeline located near Delhi, Louisiana. CGT, a subsidiary of Columbia Pipeline Group, Inc.,
operates an interstate pipeline system consisting of approximately 3,400 miles of pipeline and 11
compressor stations, located primarily in Louisiana, Mississippi, Tennessee, and Kentucky.1
After reviewing CGT’s records related to the Incident, the Director, Southwest, Region, OPS
(Director), issued to Respondent, by letter dated January 19, 2016, a Notice of Probable
Violation and Proposed Civil Penalty (Notice). In accordance with 49 C.F.R. § 190.207, the
Notice proposed finding that CGT had violated 49 C.F.R. § 191.15 and proposed assessing a
civil penalty of $33,100 for the alleged violation.
CGT responded to the Notice by letter dated February 23, 2016 (Response). Respondent
contested the allegation of violation and requested that the proposed civil penalty be withdrawn.
Respondent did not request a hearing and therefore has waived its right to one.
FINDING OF VIOLATION
The Notice alleged that Respondent violated 49 C.F.R. Part 191, as follows:
1 Pipeline Safety Violation Report (Violation Report), (05/27/2015) (on file with PHMSA), at 1; See also,
Columbia Pipeline Group, Our Companies – Columbia Gulf Transmission, https://www.cpg.com/about-us/our-
companies (last accessed on February 28, 2016).



CPF No. 4-2016-1001

Item 1: The Notice alleged that Respondent violated 49 C.F.R. § 191.15(c), which states:
§ 191.15 Transmission systems; gathering systems; and liquefied
natural gas facilities: Incident report.
(a) Transmission or Gathering. Each operator of a transmission or
a gathering pipeline system must submit DOT Form PHMSA F 7100.2 as
soon as practicable but not more than 30 days after detection of an incident
required to be reported under § 191.5 of this part. . .
(c) Supplemental report. Where additional related information is
obtained after a report is submitted under paragraph (a) or (b) of this section,
the operator must make a supplemental report as soon as practicable with a
clear reference by date to the original report.
The Notice alleged that Respondent violated § 191.15(c) by failing to make a supplemental
report to PHMSA as soon as practicable after obtaining additional information about the
circumstances surrounding an incident. Specifically, the Notice alleged that on April 25, 2014,
CGT experienced an accident on its ML300 natural gas pipeline near Delhi, Louisiana, and filed
an incident report (PHMSA Form F 7100.2) on May 22, 2014, as required by § 191.15(a)). The
Notice further alleged that in its initial report, CGT listed the cause of the Incident as
“unknown/still under investigation.” Further, on April 7, 2015, CGT allegedly received a
metallurgical analysis “that provided the necessary information to determine a probable cause of
failure [but CGT] did not file a supplemental final report until receiving a request from the
Southwest Region.” When CGT did file a supplemental report with PHMSA on September 30,
2015, it allegedly only listed the cause of the Incident as “Miscellaneous.” Finally, on November
29, 2015, after repeated requests from PHMSA, CGT allegedly filed a final supplemental report
that properly listed the cause of the Incident as “fatigue.”
Respondent contested this allegation of violation. While it did not dispute the facts alleged in the
Notice, CGT asserted that it filed the September 30, 2015 supplemental report “as soon as
practicable” once “the metallurgical analysis report was finalized on April 7, 2015.”2 First, the
company argued that Part 191 does not define the phrase “as soon as practicable,” unlike 49
C.F.R. § 195.54(b), which requires operators to file supplemental accident reports on hazardous
liquid pipelines within 30 days after receiving any changes in the information reported or
additions to the original report.3
Second, CGT argued that while the September 30, 2015 supplemental report listed the cause of
the accident as “Miscellaneous,” the report also provided an “additional description clearly
2 Response, at 2.
3 Id. Respondent argues that because the parallel provision in § 195.54(b) for hazardous liquid pipeline accidents
specifies a 30-day deadline for submitting the same type of supplemental report but § 191.15(c) does not, this
somehow suggests that time is not of the essence in filing supplemental reports on gas pipeline accidents. This is a
distinction without a difference. If anything, the 30-day requirement in Part 195 reinforces the allegation here that
CGT failed to file a supplemental report “as soon as practicable,” since CGT did not file a supplemental report until
well past 30 days.



CPF No. 4-2016-1001

stating the cause was fatigue consistent with the metallurgical analysis report.”4 Finally, CGT
stated that it submitted the November 29, 2015 supplemental report to address requests from
PHMSA – including PHMSA’s request that CGT list “fatigue” in Section G of the report and
that it classify the cause of the Incident as coming under the category “Pipe, Weld or Joint
Failure.”
Upon review of Respondent’s arguments, I find each of them unpersuasive. As for its first
argument, CGT correctly notes that the phrase “as soon as practicable” is not defined in
§ 191.15(c). The Code does not set a prescribed number of days needed to meet the “as soon as
practicable” standard since each situation is different. However, PHMSA’s prior enforcement
decisions and a common-sense reading of the phrase dictate that once an operator has sufficient
information to determine the cause of an accident, it must promptly convey that information to
PHMSA through a supplemental report.
The facts in this case are strikingly similar to those in a previous PHMSA enforcement action, In
the Matter of El Paso Natural Gas Company, CPF No. 4-2010-1005 (October 24, 2012).5 In that
case, PHMSA found that the company had violated § 191.15 by failing to file a supplemental
incident report roughly eight months after receiving a detailed metallurgical analysis report on
the probable cause of a failure.6 In the present case, on April 7, 2015, Respondent received a
metallurgical analysis listing the cause of the Incident as “fatigue” but did not submit any
supplemental report to PHMSA containing this new information until September 30, 2015 – 176
days after receiving the metallurgical analysis and only after a request from the OPS Southwest
Region. Further, Respondent did not file a final supplemental report listing the cause of the
Incident as “fatigue” until November 29, 2015 – 236 days after receiving the metallurgical
report.
One of the main purposes of DOT Form PHMSA F 7100.2 is to document an operator’s ongoing
efforts to determine the cause of an accident. While the root cause of an accident may not be
known immediately, § 191.15(a) places a responsibility on the operator to report an accident as
soon as practicable, but not more than 30 days, following detection of the incident and to report
what is known about its probable cause. Under paragraph (c), the operator also has an ongoing
obligation to inform PHMSA as soon as the company becomes aware of “additional
information” about the accident, including its cause. Fulfilling this obligation allows both the
operator and PHMSA to take appropriate action to address any underlying issues relating to the
cause of the incident, and the agency can use this critical information to assemble and analyze
data from other reportable incidents so as to promote safety and prevent similar accidents
throughout the industry. Therefore, this information-collection process cannot be accurate or
achieve its purpose if the forms are not completed properly and updated as soon as practicable
after new information is received.

(November 6, 2009) (available at www.phmsa.dot.gov/pipeline/enforcement) (finding that CenterPoint violated 49
C.F.R. § 191.15(b) [now § 191.15(c)] by failing to file a supplemental report roughly six months after receiving a
final metallurgical report determining the cause of a failure)



CPF No. 4-2016-1001

CGT has suggested in its Response that its failure to file a supplemental report that accurately
and timely identified the cause of this incident was merely a technical violation and that the
company did not need to include additional, or more accurate, information in its September 30,
2015 supplemental report or to file another report. This is incorrect. The September 30, 2015
supplemental report still listed the cause of the Incident as being “Miscellaneous,” when, in fact,
the cause had been identified by the metallurgical report as “fatigue.”
Thus, the September 30, 2015 supplemental report was both late and factually incomplete. It
was only after repeated requests from PHMSA that CGT eventually filed a proper supplemental
report on November 29, 2015. Accordingly, after considering all of the evidence, I find that
Respondent violated § 191.15(c) by failing to make a supplemental report to PHMSA as soon as
practicable after obtaining additional information about the cause of the Incident.
This finding of violation will be considered a prior offense in any subsequent enforcement action
taken against Respondent.
ASSESSMENT OF PENALTY
Under 49 U.S.C. § 60122, Respondent is subject to an administrative civil penalty not to exceed
$200,000 per violation for each day of the violation, up to a maximum of $2,000,000 for any
related series of violations. In determining the amount of a civil penalty under 49 U.S.C. § 60122
and 49 C.F.R. § 190.225, I must consider the following criteria: the nature, circumstances, and
gravity of the violation, including adverse impact on the environment; the degree of
Respondent’s culpability; the history of Respondent’s prior offenses; any effect that the penalty
may have on its ability to continue doing business; and the good faith of Respondent in
attempting to comply with the pipeline safety regulations. In addition, I may consider the
economic benefit gained from the violation without any reduction because of subsequent
damages, and such other matters as justice may require. The Notice proposed a total civil
penalty of $33,100 for the violation cited above.
Item 1: The Notice proposed a civil penalty of $33,100 for Respondent’s violation of 49 C.F.R.
§ 191.15(c), for failing to make a supplemental report to PHMSA on DOT Form PHMSA F
7100.2 as soon as practicable after obtaining additional information about the cause of the
Incident. As discussed above, I found that Respondent filed a supplemental report
approximately 176 days after receiving a critical metallurgical report that identified the cause of
the Incident as fatigue and that such an extended period of time was not “as soon as practicable”
after obtaining such additional information.
I further find the proposed penalty to be reasonable and assessed in accordance with the penalty
assessment criteria outlined in 49 C.F.R. § 190.225. While the violation did not affect the
integrity or safety of CGT’s pipeline, the requirement to file supplemental reports as soon as
practicable after obtaining additional information is clear and unambiguous. Reporting
requirements such as this are critical to ensure that PHMSA and the public promptly learn the
causes of gas pipeline incidents and are able to take timely action to address them. Accordingly,
having reviewed the record and considered the assessment criteria, I assess Respondent a civil



CPF No. 4-2016-1001
Page 6
penalty of $33,100 for violating 49 C.F.R. § 191.15(c).
In summary, having reviewed the record and considered the assessment criteria for the Item cited
above, I assess Respondent a total civil penalty of $33,100.
Payment of the civil penalty must be made within 20 days of service. Federal regulations
(49 C.F.R. § 89.21(b)(3)) require such payment to be made by wire transfer through the Federal
Reserve Communications System (Fedwire), to the account of the U.S. Treasury. Detailed
instructions are contained in the enclosure. Questions concerning wire transfers should be
directed to: Financial Operations Division (AMK-325), Federal Aviation Administration, Mike
Monroney Aeronautical Center, P.O. Box 269039, Oklahoma City, Oklahoma 73125. The
Financial Operations Division telephone number is (405) 954-8845.
Failure to pay the $33,100 civil penalty will result in accrual of interest at the current annual rate
in accordance with 31 U.S.C. § 3717, 31 C.F.R. § 901.9 and 49 C.F.R. § 89.23. Pursuant to
those same authorities, a late penalty charge of six percent (6%) per annum will be charged if
payment is not made within 110 days of service. Furthermore, failure to pay the civil penalty
may result in referral of the matter to the Attorney General for appropriate action in a district
court of the United States.
Under 49 C.F.R. § 190.243, Respondent has the right to submit a Petition for Reconsideration of
this Final Order. The petition must be sent to: Associate Administrator, Office of Pipeline
Safety, PHMSA, 1200 New Jersey Avenue, SE, East Building, 2nd Floor, Washington, DC
20590, with a copy sent to the Office of Chief Counsel, PHMSA, at the same address. PHMSA
will accept petitions received no later than 20 days after receipt of service of the Final Order by
the Respondent, provided they contain a brief statement of the issue(s) and meet all other
requirements of 49 C.F.R. § 190.243. The filing of a petition automatically stays the payment of
any civil penalty assessed but does not stay any other provisions of the Final Order, including
any required corrective actions. If Respondent submits payment of the civil penalty, the Final
Order becomes the final administrative decision and the right to petition for reconsideration is
waived.
The terms and conditions of this Final Order are effective upon service in accordance with
49 C.F.R. § 190.5.
