FINAL ORDER
From July 25 through July 29, 2022, pursuant to 49 U.S.C. § 60117, a representative of the
Pipeline and Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety
(OPS), inspected Contango Resources, LLC’s1 (Contango or Respondent) control room
procedures and records in Midwest, Wyoming.
As a result of the inspection, the Director, Western Region, OPS (Director), issued to
Respondent, by letter dated October 25, 2023, a Notice of Probable Violation and Proposed
Compliance Order (Notice). In accordance with 49 C.F.R. § 190.207, the Notice proposed
finding that Contango had committed three violations of 49 C.F.R. Part 195 and proposed
ordering Respondent to take certain measures to correct the alleged violations.
Contango responded to the Notice by letter dated November 21, 2023 (Response). Contango
offered additional information in response to the Notice and requested that Item 2 be withdrawn.
Respondent did not request a hearing and therefore has waived its right to one.
FINDINGS OF VIOLATION
The Notice alleged that Respondent violated 49 C.F.R. Part 195, as follows:
Item 1: The Notice alleged that Respondent violated 49 C.F.R. § 195.446(c)(3), which states:
§ 195.446 Control room management.
(a) ….
(c) Provide adequate information. Each operator must provide its

controllers with the information, tools, processes and procedures necessary
for the controllers to carry out the roles and responsibilities the operator has
defined by performing each of the following:
(1) ….
(3) Test and verify an internal communication plan to provide adequate
means for manual operation of the pipeline safely, at least once each
calendar year, but at intervals not to exceed 15 months;
The Notice alleged that Respondent violated 49 C.F.R. § 195.446(c)(3) by failing to test and
verify its internal communication plan as required. Specifically, the Notice alleged that
Contango’s Environment Health, & Safety DOT CO2 Pipeline Control Room Management Plan
(Rev. 0; March 1, 2022), section 5.3 Internal Communication Plan, stated that tabletop drills
would be the primary method for testing its internal communications plan. The Notice alleged
that the tabletop drills did not test the ability of Contango’s employees to communicate with
control room personnel from the pipeline right-of-way locations in the event that employees are
deployed to manually operate the pipeline. The Notice further alleged that Contango’s internal
communication plan failed to provide details as to when employees would deploy to the pipeline
rights-of-way and how communications between the deployed employees and the control room
personnel would occur and failed to provide adequate means for the safe manual operation of the
pipeline.
Respondent did not contest this allegation of violation and provided additional information in its
Response, including its amended internal communication plan. Accordingly, after considering
all of the evidence, I find that Respondent violated 49 C.F.R. § 195.446(c)(3) by failing to test
and verify its internal communication plan to provide adequate means for manual operation of
the pipeline safely, at least once each calendar year, but at intervals not to exceed 15 months.
Item 2: The Notice alleged that Respondent violated 49 C.F.R. § 195.446(c)(4), which states:
§ 195.446 Control room management.
(a) ….
(c) Provide adequate information. Each operator must provide its
controllers with the information, tools, processes and procedures necessary
for the controllers to carry out the roles and responsibilities the operator has
defined by performing each of the following:
(1) ….
(4) Test any backup SCADA systems at least once each calendar year,
but at intervals not to exceed 15 months; . . .
The Notice alleged that Respondent violated 49 C.F.R. § 195.446(c)(4) by failing to test its
backup supervisory control and data acquisition (SCADA) systems at least once each calendar
year, but at intervals not to exceed 15 months as required. Specifically, the Notice alleged that
Contango did not have a procedure to test backup SCADA systems and could not provide
records that it had tested its backup SCADA systems.
In its Response, Respondent did not deny that it had failed to test its backup SCADA systems,



but explained that it had determined following PHMSA’s inspection that it did not maintain
backup SCADA equipment specific to only the pipeline, and therefore could not perform testing
as required by § 195.446(c)(4) without significant operational and financial impact. Respondent
also stated that it had amended its procedures to remove language regarding backup SCADA
testing and added a requirement to manually shut in the pipeline in the event of a SCADA
system failure and provided a copy of the revised procedure in its Response. Respondent stated
that the additional information provided in its Response warrants a withdrawal of Item 2.
After considering all of the evidence, I find that Respondent failed to test its backup SCADA
systems at least once each calendar year, but at intervals not to exceed 15 months. Respondent’s
argument that it is not required to test backup SCADA systems because it “does not maintain
backup SCADA equipment specific to only the pipeline” and thus testing would cause
significant operational and financial impact, does not excuse compliance with the pipeline safety
regulations.2 Section 195.446(c)(4) requires testing of any backup SCADA systems that an
operator maintains. Part 195 defines the term “SCADA system” to mean “a computer-based
system or systems used by a controller in a control room that collects and displays information
about a pipeline facility and may have the ability to send commands back to the pipeline
facility.”3 PHMSA’s control room management FAQs discuss backup SCADA systems as
“independent or redundant systems that provide similar functionality to the primary SCADA
system.”4 Here, Respondent maintains an Allen-Bradley distributed control system (DCS) that is
used to monitor and control the pipeline with Human Machine Interfaces (HMIs) at several sites
along the pipeline. Each HMI site is identical and can fully control the pipeline; therefore, each
HMI site is considered a redundant or backup control room. Respondent, therefore, must have
procedures for testing these backup systems. Further, the pipeline safety regulations do not
distinguish between SCADA systems that solely operate the pipeline and those that may include
other functions. Additionally, the regulations do not waive compliance for testing backup
SCADA systems that operators have in place based on its potential financial or operational
burden. Accordingly, I find that Respondent violated 49 C.F.R. § 195.446(c)(4) by failing to test
its backup SCADA systems.
Item 3: The Notice alleged that Respondent violated 49 C.F.R. § 195.446(e)(5), which states:
§ 195.446 Control room management.
(a) ….
(e) Alarm management. Each operator using a SCADA system must
have a written alarm management plan to provide for effective controller
response to alarms. An operator’s plan must include provisions to:
(1) ….
(5) Monitor the content and volume of general activity being directed

system in order to be considered a backup system.



to and required of each controller at least once each calendar year, but at
intervals not exceeding 15 months, that will assure controllers have
sufficient time to analyze and react to incoming alarms; and
The Notice alleged that Respondent violated 49 C.F.R. § 195.446(e)(5) by failing to monitor the
content and volume of general activity being directed to and required of each controller at least
once each calendar year, but at intervals not exceeding 15 months, that will ensure controllers
have sufficient time to analyze and react to incoming alarms. Specifically, the Notice alleged
that Respondent could not provide any records demonstrating that it monitored the content and
volume of general activity being directed to and required of each controller at least once each
calendar year, but at intervals not exceeding 15 months, in order to verify controllers have
sufficient time to analyze and react to incoming alarms.
Respondent did not contest this allegation of violation and provided additional information in its
Response, including its amended control room management procedure. Accordingly, after
considering all of the evidence, I find that Respondent violated 49 C.F.R. § 195.446(e)(5) by
failing to monitor the content and volume of general activity being directed to and required of
each controller at least once each calendar year, but at intervals not exceeding 15 months.
These findings of violation will be considered prior offenses in any subsequent enforcement
action taken against Respondent.
COMPLIANCE ORDER
The Notice proposed a compliance order with respect to Items 1, 2, and 3 in the Notice for
violations of 49 C.F.R. §§ 195.446(c)(3), 195.446(c)(4), and 195.446(e)(5), respectively. Under
49 U.S.C. § 60118(a), each person who engages in the transportation of hazardous liquid or
carbon dioxide or who owns or operates a pipeline facility is required to comply with the
applicable safety standards established under chapter 601. The Director has indicated that
Respondent has taken the following actions to address some of the cited violations:
With respect to the violation of § 195.446(c)(3) (Item 1), Respondent has amended its Standard
Operating Guideline for: Execution of the Internal Communication Plan (PL-General-005, Rev.
0), section 4 Testing Protocol, to provide for dispatching employees to pipeline locations to test
and verify the ability for communications between the control room and field locations. The
Director indicated that the amended procedure satisfied the terms of the proposed compliance
order in part, therefore, compliance actions for Item 1 are modified.
With respect to the violation of § 195.446(c)(4) (Item 2), Respondent amended its
Environment Health, & Safety DOT CO2 Pipeline Control Room Management Plan, section 5.4
Backup SCADA System, to indicate that backup SCADA systems are currently not applicable
and that in the event of a SCADA system failure, the pipeline would be manually shut down.
The Director indicated that the amended procedure did not satisfy the terms of the proposed
compliance order. For the reasons discussed above that found Respondent in violation of
§ 195.446(c)(4), I find that Respondent has not taken the necessary actions to address the cited



violation, and therefore the compliance actions for Item 2 are not modified.
With respect to the violation of § 195.446(e)(5) (Item 3), Respondent has amended its
Environment Health, & Safety DOT CO2 Pipeline Control Room Management Plan, Appendix B
Alarm Management Plan, to add a new section 4.0 Information Content & Volume to provide
detailed instructions for reviewing and documenting the analysis of the content and volume of
general activity being directed to and required of each controller that will ensure controllers have
sufficient time to analyze and react to incoming alarms. The Director indicated that the amended
procedure satisfied the terms of the proposed compliance order in part, and therefore compliance
actions for Item 3 are modified.
For the above reasons, the Compliance Order is modified as set forth below.
Pursuant to the authority of 49 U.S.C. § 60118(b) and 49 C.F.R. § 190.217, Respondent is
ordered to take the following actions to ensure compliance with the pipeline safety regulations
applicable to its operations:
1. With respect to the violation of § 195.446(c)(3) (Item 1), Respondent must
conduct a test of the internal communications plan using its amended procedure and
submit documentation of the test to PHMSA within 60 days of receipt of the Final
Order.
2. With respect to the violation of § 195.446(c)(4) (Item 2), Respondent must amend
its procedures to provide detailed instructions for the testing of each backup SCADA
system, as well as documenting each test. Respondent must test each backup
SCADA system using its amended procedures and submit its amended procedure and
records documenting each backup SCADA system test to PHMSA within 60 days of
receipt of the Final Order.
3. With respect to the violation of § 195.446(e)(5) (Item 3), Respondent must
conduct a review and analysis of the content and volume of general activity being
directed to and required of each controller using its amended procedure and submit
documentation of the review and analysis to PHMSA within 60 days of receipt of the
Final Order.
The Director may grant an extension of time to comply with any of the required items upon a
written request timely submitted by the Respondent and demonstrating good cause for an
extension.
PHMSA requests that Respondent maintain documentation of the safety improvement costs
associated with fulfilling this Compliance Order and submit the total to the Director. It is
requested that these costs be reported in two categories: (1) total cost associated with
preparation/revision of plans, procedures, studies and analyses; and (2) total cost associated with
replacements, additions and other changes to pipeline infrastructure.
Failure to comply with this Order may result in administrative assessment of civil penalties not



to exceed $200,000, as adjusted for inflation (see 49 C.F.R. § 190.223 for adjusted amounts), for
each violation for each day the violation continues or in referral to the Attorney General for
appropriate relief in a district court of the United States.
Under 49 C.F.R. § 190.243, Respondent may submit a Petition for Reconsideration of this Final
Order to the 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. The written petition must be received no later than
20 days after receipt of the Final Order by Respondent. Any petition submitted must contain a
statement of the issue(s) and meet all other requirements of 49 C.F.R. § 190.243. The terms of
the order, including corrective action, remain in effect unless the Associate Administrator, upon
request, grants a stay.
The terms and conditions of this Final Order are effective upon service in accordance with 49
C.F.R. § 190.5.
