NOTICE OF AMENDMENT
OVERNIGHT EXPRESS DELIVERY
August 18, 2022
Mr. Andre Cangucu
President and Chief Executive Officer
Neptune LNG, LLC
1360 Post Oak Boulevard #400
Houston, Texas 77056
CPF 1-2022-048-NOA
Dear Mr. Cangucu:
From June 7, 2021 through June 11, 2021, a representative of the Pipeline and Hazardous Materials
Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code inspected
Neptune LNG, LLC’s (Neptune) procedures for its underwater facilities located on the outer
continental shelf adjacent to Massachusetts Bay.
On the basis of the inspection, PHMSA has identified the apparent inadequacies found within
Neptune’s written procedures, as described below:
1. § 191.22 National Registry of Operators.
(a) …
(c) Changes. Each operator of a gas pipeline, gas pipeline facility,
UNGSF, LNG plant, or LNG facility must notify PHMSA electronically
through the National Registry of Operators at
https://portal.phmsa.dot.gov of certain events.
Neptune’s written reporting procedures were inadequate to ensure safe operation of a pipeline
facility. Specifically, Neptune failed to have a procedure addressing notifications to PHMSA of
changes in accordance with § 191.22(c).
During the inspection PHMSA requested Neptune’s procedures regarding reporting of changes
and was provided Neptune’s Neptune LNG Deepwater Port: Operations, Maintenance, and



Emergency Response Procedure Manual: Appendix “J” To The Neptune Deepwater Port
Operations Manual, dated May 2020 (O&M). Specifically, Section 1 in the O&M, Reporting
Procedures – 49 CFR 192.605(b)(4), failed to include a process for reporting changes in entity,
acquisition/divestiture, and construction/update/uprate. Processes should include an itemization
of the types of activities or events in which PHMSA must be notified, and the time frame in which
the notifications must be made. Additionally, the website listed in the procedure failed to take the
user to the appropriate place to meet the reporting requirements of § 191.22(c).
Therefore, Neptune’s written reporting procedures were inadequate to ensure safe operation of a
pipeline facility in accordance with § 191.22(c). Neptune must revise its procedures to address
this deficiency.
2. § 192.605 Procedural manual for operations, maintenance, and emergencies.
(a) …
(b) Maintenance and normal operations. The manual required by
paragraph (a) of this section must include procedures for the following,
if applicable, to provide safety during maintenance and operations.
(1) Operating, maintaining, and repairing the pipeline in
accordance with each of the requirements of this subpart and Subpart
M of this part.
Neptune’s written procedures for maintenance and normal operations were inadequate to ensure
safe operation of a pipeline facility in accordance with § 192.605(b)(1). Specifically, the
Abandonment or Deactivation Procedures in the O&M failed to include sufficient details
regarding the requirements for the abandonment and deactivation of pipelines and facilities
identified in § 192.727(g)(1).
1
1 § 192.727 Abandonment or deactivation of facilities.
(a) …
(g) For each abandoned offshore pipeline facility or each abandoned onshore pipeline facility that crosses over, under
or through a commercially navigable waterway, the last operator of that facility must file a report upon abandonment
of that facility.
(1) The preferred method to submit data on pipeline facilities abandoned after October 10, 2000 is to the National
Pipeline Mapping System (NPMS) in accordance with the NPMS “Standards for Pipeline and Liquefied Natural Gas
Operator Submissions.” To obtain a copy of the NPMS Standards, please refer to the NPMS homepage at
http://www npms.phmsa.dot.gov or contact the NPMS National Repository at 703-317-3073. A digital data format is
preferred, but hard copy submissions are acceptable if they comply with the NPMS Standards. In addition to the
NPMS-required attributes, operators must submit the date of abandonment, diameter, method of abandonment, and
certification that, to the best of the operator's knowledge, all of the reasonably available information requested was
provided and, to the best of the operator's knowledge, the abandonment was completed in accordance with applicable
laws. Refer to the NPMS Standards for details in preparing your data for submission. The NPMS Standards also
include details of how to submit data. Alternatively, operators may submit reports by mail, fax or e-mail to the Pipeline
and Hazardous Materials Safety Administration, U.S. Department of Transportation, PHP-10, 1200 New Jersey
Avenue, SE., Washington, DC 20590; fax (202) 366-4566; e-mail InformationResourcesManager@phmsa.dot.gov.
The information in the report must contain all reasonably available information related to the facility, including
information in the possession of a third party. The report must contain the location, size, date, method of abandonment,
and a certification that the facility has been abandoned in accordance with all applicable laws.



During the inspection PHMSA reviewed Neptune’s O&M. The O&M failed to adequately detail
a process for the abandonment and deactivation of pipelines and facilities. The O&M failed to
state how to file an abandonment and deactivation report, who must file the report, and when it
must be done. The O&M also failed to include details such as how to submit mapped facilities to
the National Pipeline Mapping System and what information must be submitted, such as the
location of the facility, size, date, and method of abandonment.
Therefore, Neptune’s written procedures for maintenance and normal operations were inadequate
to ensure safe operation of a pipeline facility in accordance with §§ 192.605(b)(1) and
192.727(g)(1). Neptune must revise its procedures to address this deficiency.
3. § 192.605 Procedural manual for operations, maintenance, and emergencies.

(b) Maintenance and normal operations. The manual required by
paragraph (a) of this section must include procedures for the following,
if applicable, to provide safety during maintenance and operations.
(1) Operating, maintaining, and repairing the pipeline in
accordance with each of the requirements of this subpart and Subpart
M of this part.
Neptune’s written procedures for maintenance and normal operations were inadequate to ensure
safe operation of a pipeline facility in accordance with § 192.605(b)(1). Specifically, Neptune’s
O&M failed to include sufficient detail regarding a process for determining the maximum
allowable operating pressure (MAOP) of a pipeline segment in accordance with § 192.619(a).
2
During the inspection PHMSA reviewed the MAOP Procedures in the O&M. The O&M failed to
include a process for determining the MAOP for a pipeline segment in accordance with §
192.619(a). Specifically, the O&M failed to include processes or requirements for identifying
conditions which may limit MAOP. Conditions that may limit MAOP include, but are not limited
to:
1. The design pressure of the weakest element in the segment as determined in accordance
with Part 192, Subparts C and D.
2. The pressure obtained by test pressures that incorporate safety factors that are
commensurate with the established class location in accordance with § 192.619(a)(2)(ii).
Therefore, Neptune’s written procedures for maintenance and normal operations were inadequate
to ensure safe operation of a pipeline facility in accordance with §§ 192.605(b)(1) and 192.619(a).
Neptune must revise its procedures to address this deficiency.
4. § 192.605 Procedural manual for operations, maintenance, and emergencies.
2 § 192.619 Maximum allowable operating pressure: Steel or plastic pipelines.
(a) No person may operate a segment of steel or plastic pipeline at a pressure that exceeds a maximum allowable
operating pressure (MAOP) determined under paragraph (c), (d), or (e) of this section, or the lowest of the following:



(a) …
(b) Maintenance and normal operations. The manual required by
paragraph (a) of this section must include procedures for the following,
if applicable, to provide safety during maintenance and operations.
(1) Operating, maintaining, and repairing the pipeline in
accordance with each of the requirements of this subpart and Subpart
M of this part.
Neptune’s written procedures for maintenance and normal operations were inadequate to ensure

Field Repair Procedure in the O&M failed to include sufficient details regarding making
permanent field repairs of leaks for submerged pipeline facilities pursuant to § 192.717(b)(4).
3
During the inspection PHMSA reviewed Neptune’s O&M. The O&M guidance for repairs to
localized corrosion was limited to a reference to § 192.717 and provided inadequate guidance that
stated “an experienced contractor qualified in this type of repair will be utilized.
” The O&M failed
to include a detailed process for making permanent field repairs of leaks on submerged
transmission lines in accordance with § 192.717(b)(4).
Therefore, Neptune’s written procedures for maintenance and normal operations were inadequate
to ensure safe operation of a pipeline facility in accordance with §§ 192.605(b)(1) and
192.717(b)(4). Neptune must revise its procedures to address this deficiency.
5. § 192.605 Procedural manual for operations, maintenance, and emergencies.
(a) …
(b) Maintenance and normal operations. The manual required by

Each permanent field repair of a leak on a transmission line must be made by-
(a) …
(b) Repairing the leak by one of the following methods:
(1) …
(4) If the leak is on a submerged offshore pipeline or submerged pipeline in inland navigable waters, mechanically
apply a full encirclement split sleeve of appropriate design.
4 § 192.629 Purging of pipelines.
(a) When a pipeline is being purged of air by use of gas, the gas must be released into one end of the line in a moderately
rapid and continuous flow. If gas cannot be supplied in sufficient quantity to prevent the formation of a hazardous
mixture of gas and air, a slug of inert gas must be released into the line before the gas.



During the inspection PHMSA reviewed the Pipeline Purging Procedures in the O&M. This
section failed to include a detailed process that describes how to purge the pipeline when it is
removed from and placed back into service. The O&M failed to include details such as:
• Measured levels of gas in air or inert medium mixtures.
• Identifying the location of purge points.
• Use of critical valves to control flow.
• The manner by which turbulent flow would be achieved (e.g., calculated purging velocity
to assure turbulent flow).
• Calculated times needed to assure purge.
• Qualifications required for performing purging and operating valves.
• Recordkeeping requirements for all purging data.
Therefore, Neptune’s written procedures for maintenance and normal operations were inadequate
to ensure safe operation of a pipeline facility in accordance with §§ 192.605(b)(1) and 192.629(a).
Neptune must revise its procedures to address this deficiency.
6. § 192.605 Procedural manual for operations, maintenance, and emergencies.

O&M failed to include sufficient details regarding requirements for the design, installation,
operation, and maintenance of cathodic protection systems, to be carried out by, or under the
direction of, a person qualified in pipeline corrosion control methods as required by § 192.453.
5
During the inspection PHMSA reviewed Neptune’s O&M. Item 1 in the Corrosion Control
Procedures in the O&M failed to include a process requiring corrosion control to be carried out
by, or under the direction of, qualified personnel, as required by § 192.453. The O&M failed to
include a definition or list of criteria defining what a qualified person is, or specifically identifying
the position or individuals performing these functions. Additionally, the O&M did not identify
what documentation is needed to substantiate qualification(s).
5 § 192.453 General.
The corrosion control procedures required by § 192.605(b)(2), including those for the design, installation, operation,
and maintenance of cathodic protection systems, must be carried out by, or under the direction of, a person qualified

Neptune’s written procedures for maintenance and normal operations were inadequate to ensure
safe operation of a pipeline facility. Specifically, Neptune’s O&M failed to include a detailed
procedure for periodically reviewing the work done by operator personnel to determine the



effectiveness and adequacy of the procedures used in normal operation and maintenance and
modifying the procedures when deficiencies are found in accordance with § 192.605(b)(8).
During the inspection PHMSA reviewed Neptune’s O&M. Specifically, Item 5 in the Normal
Operating and Maintenance Procedures in the O&M failed to indicate how the periodic review is
conducted and documented. The nature and type of work or procedure reviewed should be
documented.
Therefore, Neptune’s written procedures for maintenance and normal operations were inadequate
to ensure safe operation of a pipeline facility in accordance with § 192.605(b)(8). Neptune must
revise its procedures to address this deficiency.
9. § 192.605 Procedural manual for operations, maintenance, and emergencies.
(a) …
(c) Abnormal operation. For transmission lines, the manual
required by paragraph (a) of this section must include procedures for
the following to provide safety when operating design limits have been
exceeded:
(1) …
(2) Checking variations from normal operation after abnormal
operation has ended at sufficient critical locations in the system to
determine continued integrity and safe operation.
(3) Notifying responsible operator personnel when notice of an
abnormal operation is received.
Neptune’s written procedures for maintenance and normal operations were inadequate to ensure
safe operation of a pipeline facility. Specifically, Neptune’s O&M failed to include procedures to
provide safety when operating design limits have been exceeded in accordance with
§ 192.605(c)(2) and (c)(3).
During the inspection PHMSA reviewed Neptune’s O&M regarding abnormal operations
procedures and noted the following inadequacies:
1. Item 6 in the Abnormal Operating Procedures in the O&M failed to include a detailed
process for checking variations from normal operation after abnormal operation has ended
at sufficient critical locations in the system to determine continued integrity and safe
operation. Specifically, the O&M failed to include a detailed process for checking

2. The O&M failed to include a detailed process for notifying responsible operator personnel
when notice of an abnormal operation is received in accordance with § 192.605(c)(3).
Specifically, Item 7 in the Abnormal Operating Procedures in the O&M failed to identify
the person-in-charge (PIC) or a process for identifying the PIC. Further, the O&M failed



to include a contact number or identify the specific person or department at Enbridge that
must be contacted in the event of an abnormal operation. The O&M failed to indicate how
abnormal operations would be reported while there are no LNG deliveries at port.
Therefore, Neptune’s written procedures for maintenance and normal operations were inadequate
to ensure safe operation of a pipeline facility in accordance with § 192.605(c)(2) and (c)(3).
Neptune must revise its procedures to address these deficiencies.
10. § 192.605 Procedural manual for operations, maintenance, and emergencies.

Furthermore, Item 15 in the Emergency Procedures in the O&M stated that “the annual drill
requirement will be waived until such time as operations under the MARAD license issued to the
Port are fully reactivated. During this waiver period, any changes to the Port including but not
limited to operational or physical shall be communicated to the appropriate public officials as soon
as practicable.” While port operations may be suspended by MARAD, the Neptune pipeline
remains active. As such, it is subject to the requirements of Part 192. Therefore, Neptune must
comply with the liaison requirements in § 192.615(c) even if port operations are suspended by
MARAD.
Therefore, Neptune’s written procedures for emergency response were inadequate to ensure safe
operation of a pipeline facility in accordance with §§ 192.605(e) and 192.615(c). Neptune must
revise its procedures to address these deficiencies.

(7) …
(8) Notifying appropriate fire, police, and other public officials of
gas pipeline emergencies and coordinating with them both planned
responses and actual responses during an emergency.
Neptune’s written procedures for minimizing the hazards resulting from a gas pipeline emergency
were inadequate to ensure safe operation of a pipeline facility. Specifically, Neptune’s O&M
failed to include sufficient details regarding various topics required under § 192.615(a)(1), (a)(4),
(a)(6), and (a)(8).
PHMSA reviewed the O&M and discovered the following inadequacies:
1. The O&M failed to include a process for receiving, identifying, and classifying notices of
events which need immediate response as required by § 192.615(a)(1). Specifically, Item
2 in the Emergency Procedures in the O&M did not include an emergency contact phone
number or other means by which the operator receives notices of events which need
immediate response. The O&M failed to include a process for identifying who receives
initial notifications and how notifications are documented and communicated to those
responsible for identifying and classifying events that require immediate response.
2. The O&M failed to include a process for ensuring the availability of personnel, equipment,
tools, and materials as needed at the scene of an emergency as required by § 192.615(a)(4).
Specifically, Item 5 in the Emergency Procedures in the O&M failed to include a process
for ensuring the availability of personnel, equipment, tools, and materials as needed at the
scene of an emergency “in the event when there is no [shuttle regasification vessel] at the
Port and a [support vessel (SV)] is unavailable.” The O&M failed to identify specifically
where the backup vessel is located, the operator of the backup vessel, or how it may be
reached during an emergency. Furthermore, the O&M failed to identify the backup vessel
personnel and their qualifications to respond to a pipeline emergency. The O&M also
failed to identify the equipment, tools and materials that would be deployed in the event of
a pipeline emergency.
3. The O&M failed to include a process for the emergency shutdown or pressure reduction in
any section of pipeline system necessary to minimize the hazards to life of property as
required by § 192.615(a)(6). Specifically, Item 7 in the Emergency Procedures in the
O&M failed to identify or describe each emergency shut down system that controls gas
flow to the pipeline. There was no identification of safety-related conditions that may
require emergency shutdown or pressure reduction in any section of pipeline system
necessary to minimize the hazards to life of property. The O&M failed to identify the
circumstances that would require a shutdown. In addition, the O&M failed to identify



adequate details of the pipeline shutdown procedure or where the pipeline shutdown
procedure is located or how it is activated.
4. The O&M failed to include a process for notifying appropriate officials of gas pipeline
emergencies and coordinating with them both planned responses and actual responses
during an emergency as required by § 192.615(a)(8). Specifically, Item 9 in the Emergency
Procedures in the O&M failed to include a process for a planned response.
Therefore, Neptune’s written procedures for minimizing the hazards resulting from a gas pipeline
emergency were inadequate to ensure safe operation of a pipeline facility in accordance with
§ 192.615(a)(1), (a)(4), (a)(6), and (a)(8). Neptune must revise its procedures to address these
deficiencies.
15. § 192.805 Qualification program.
Each operator shall have and follow a written qualification
program. The program shall include provisions to:
(a) Identify covered tasks;
Neptune’s written operator qualification program was inadequate to ensure safe operation of a
pipeline facility. Specifically, Neptune’s Northeast Gas Association Operator Qualification
Compliance Program, Rev. F, dated September 3, 2008 (OQ Plan) failed to include all covered
tasks as required by § 192.805(a).
During the inspection Neptune provided a presentation, Operator Qualification Neptune LNG,
LLC, dated May 2021). Neptune indicated that this presentation, which outlines covered tasks,
procedures, and documents that Neptune actively uses, is primarily used as Neptune’s OQ
program, rather than the OQ Plan. Neither the presentation nor any guidance for its use were
included in the OQ Plan. In addition, Appendix B of the OQ Plan, List of Covered Tasks with
Analysis failed to identify covered task # 5, Cathodic Protections, which is listed on the first slide
of the presentation. Additionally, there are covered tasks identified in Appendix B of the OQ Plan
that are not covered in the presentation.
Therefore, Neptune’s written operator qualification program was inadequate to ensure safe
operation of a pipeline facility. Neptune must revise its OQ Plan to include all details of the
process by which its personnel are trained and ensure that the covered tasks identified in the
presentation are consistent with, and included in, the OQ Plan.

OVERNIGHT EXPRESS DELIVERY
June 1, 2023
Mr. Andre Cangucu
President and Chief Executive Officer
Neptune LNG LLC
1360 Post Oak Blvd
Suite 400
Houston, TX 77056
CPF 1-2022-048-NOA
Dear Mr. Cangucu:
From June 7, 2021, through June 11, 2021, a representative of the Pipeline and Hazardous
Materials Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code
inspected Neptune LNG, LLC’s (Neptune) procedures for its underwater facilities located on the
outer continental shelf adjacent to Massachusetts Bay.
As a result of the inspection, Neptune was issued a Notice of Amendment (NOA), dated August
18, 2022. In the NOA, PHMSA proposed that amendments to the procedures be submitted by
Neptune within 30 days. In letter dated September 21, 2022, Neptune requested an additional (90)
days, no later than December 20, 2022, to submit a copy of its amended procedures. PHMSA
granted the request for a time extension made by Neptune in response letter from PHMSA to
Neptune, dated September 29, 2022. Neptune submitted revised procedures with letter, dated
December 19, 2022, absent the required OQ Manual updates. PHMSA requested further
amendment to the potential inadequacies defined in Items 3, 7, 9, 10, 14 and 15 of the NOA in
letter dated February 7, 2023. Neptune requested time extension to further amend its procedures
in letter dated February 17, 2023. PHMSA granted Neptune’s request for additional time to amend
its procedures in letter dated February 24, 2023.
Neptune provided PHMSA amended procedures on April 28th, 2023. My staff reviewed the further
amended procedures, and it appears that the inadequacies identified have been corrected.
This letter is to inform you no further action is necessary and this case is now closed. Thank you
for your cooperation.



Sincerely,
Robert Burrough
Director, Eastern Region
Pipeline and Hazardous Materials Safety Administration
