Instructions (rev xy-2012) for Form PHMSA F 7100.2-1 (rev xy-2012)
ANNUAL REPORT FOR CALENDAR YEAR 20__
NATURAL AND OTHER GAS TRANSMISSION AND GATHERING PIPELINE SYSTEMS

GENERAL INSTRUCTIONS
All section references are to Title 49 of the Code of Federal Regulations (49 CFR). The Natural and
Other Gas Transmission and Gathering Pipeline Systems Annual Report has been revised as of calendar
year (CY) 2012 affecting submissions for 2012 and beyond. This Annual Report is required per §191.17
and must be filed per §191.7. Read through the Annual Report and instructions carefully before
beginning to complete the Report. Where common data elements exist between this Report and an
operator’s NPMS submission, the data submitted by the operator on their Annual Report should be the
same as the data submitted through NPMS when possible. PHMSA encourages gas transmission
operators to send their NPMS submission to PHMSA by March 15, representing pipeline assets as of
December 31 of the previous year.
Each operator of a transmission or a gathering pipeline system must submit an Annual Report for that
system on DOT Form PHMSA 7100.2-1. This report must be submitted each year, not later than March
15, and provide information about the pipeline system as-of December 31 of the previous year. However,
for CY 2012 reports, the due date is extended until June 15, 2013. If an operator discovers an error in a
submitted annual report, a supplemental report should be filed. Changes made to the pipeline system after
the end of the reporting year should not result in a supplemental report. However, if an operator finds
records related to documenting gas transmission MAOP after the end of CY 2012 and these records result
in a change in Part Q status from incomplete records to complete records, a supplemental report should be
filed to change Part Q.
The terms “operator,” “distribution line,” “gathering line,” “Maximum Allowable Operating Pressure
(MAOP),” “offshore,” “Outer Continental Shelf,” “pipe,” “pipeline,” “pipeline facility,” “specified
minimum yield strength (SMYS),” and “transmission line” are defined in §192.3. The terms
“assessment,” and “high consequence area (HCA)” are defined in §192.903. §192.8 describes how to
identify onshore gathering lines and to determine if a gathering line is subject to regulation (i.e., is a
“regulated gathering line”). If an operator determines that its pipelines fall under the definition for
distribution lines, the operator should submit Form PHMSA F 7100.1-1 rather than this Form PHMSA F
7100.2-1.
If you need copies of the Form PHMSA F 7100.2-1 and/or instructions, they can be found
on http://www.phmsa.dot.gov/pipeline/library/forms. The documents are included in the section titled
Accident/Incident/Annual Reporting Forms.

NATURAL AND OTHER GAS TRANSMISSION AND GATHERING PIPELINE SYSTEMS

ONLINE REPORTING REQUIREMENTS
Annual Reports must be submitted online through the PHMSA Portal
at https://portal.phmsa.dot.gov/pipeline, unless an alternate method is approved (see Alternate Reporting
Methods below).
You will not be able to submit reports until you have met all of the Portal registration requirements –
see http://opsweb.phmsa.dot.gov/portal_message/PHMSA_Portal_Registration.pdf
Completing these registration requirements could take several weeks. Plan ahead and register well in
advance of the report due date.

REPORTING METHOD
Use the following procedure for online reporting:
1. Go to the PHMSA Portal at https://portal.phmsa.dot.gov/pipeline
2. Enter PHMSA Portal Username and Password ; press enter
3. Select OPID ; press “continue” button.

4. Under “Create Reports” on the left side of the screen, under Annual select “Gas
Transmission and Gathering” and proceed with entering your data. Note: Data fields
marked with a single asterisk are considered required fields that must be completed
before the system will accept your initial submission. Also, only one annual report by
commodity for an OPID may be submitted per year.
5. To save intermediate work without formally submitting it to PHMSA, click Save. To
modify a draft of an annual report that you saved, go to Saved Reports and click on
Gas Transmission and Gathering. Locate your saved report by the date, report year, or
commodity. Select the record by clicking on it once, and then click Modify above the
record.
6. Once all sections of the form have been completed, click on Validate to ensure all
required fields have been completed and data meets all other requirements. A list of
errors will be generated that must be fixed prior to submitting an Annual Report.
7. Click Submit when you have completed the Report (for either an Initial Report or a
Supplemental Report), and are ready to initiate formal submission of your Report to
PHMSA.
8. A confirmation message will appear that confirms a record has been successfully

click “Create Supplemental”.

Alternate Reporting Methods
Operators for whom electronic reporting imposes an undue burden and hardship may submit a written
request for an alternative reporting method. Operators must follow the requirements in §191.7(d) to
request an alternative reporting method and must comply with any conditions imposed as part of
PHMSA’s approval of an alternate reporting method.

SPECIFIC INSTRUCTIONS
Make an entry in each block for which data is available. Estimate data only if necessary. Avoid entering
any data as UNKNOWN or 0 (zero) except where zero is appropriate to indicate that there were no
instances or amounts of the attribute being reported.
Do not report miles of pipe, pipe segments, or pipeline in feet. When mileage for the same set of
pipelines is reported in different parts of the form, the online system will require the different parts to be
consistent. Mileage values over 60 miles must be within 0.5% of the baseline and values under 60 miles
must be within 0.3 miles. Part J, decade of installation, will serve as the mileage baseline for gas
transmission onshore, gas transmission offshore, gas gathering onshore, and gas gathering offshore. For
example, if you report 60 miles of onshore gas transmission in Part J, the onshore gas transmission
mileage by diameter in Part H must be within 0.3 miles of 60. Use the number of decimal places needed
to satisfy these consistency checks.
Enter the Calendar Year for which the Report is being filed, bearing in mind that the report should reflect
the system as-of the end of that calendar year.
The Initial Report or Supplemental Report box will be populated by the online system.
For a given OPID, a separate Annual Report is required for each Commodity Group within that
OPID. The separate Annual Report is to cover all pipeline facilities – both INTERstate and
INTRAstate – included within that OPID that serve to transport that Commodity Group. As an
example, if an operator uses a single OPID and has one set of pipeline facilities transporting natural
gas and another transporting landfill gas, this operator must file two Annual Reports – one Annual
Report covering natural gas facilities and a second for the landfill gas facilities. When a pipeline

1. Operator’s 5-digit Identification Number (OPID)
For online entries, the OPID will automatically populate based on the selection you made when
entering the Portal. If you have log-in credentials for multiple OPID, be sure the report is being
created for the appropriate OPID. Contact PHMSA’s Information Resources Manager at 202-3668075 if you need assistance with an OPID.
2. Name of Operator
This is the company name associated with the OPID. For online entries, the name will be
automatically populated based on the OPID entered in A1. If the name that appears is not correct, you
need to submit an Operator Name Change (Type A) Notification.
If the company corresponding to the OPID is a subsidiary, enter the name of the parent company.
3. Reserved
4. Headquarters address
This is the headquarters address associated with the OPID. For online entries, the address will
automatically populate based on the OPID entered in A1. If the address that appears is not correct,
you need to change it in the online Contacts module.
5. This Report pertains to the following Commodity Group
It is a PHMSA requirement that operators submit separate Reports for each Commodity Group within
a particular OPID.

Propane Gas
Landfill Gas (includes biogas)
Other Gas – If this Commodity Group is selected, report the name of the other gas in the
space provided.
Note: When a pipeline facility transports two or more of the above Commodity Groups, the pipeline
facility should be reported only once under the predominantly transported Commodity Group. For
example, if an operator has a pipeline segment that is used to transport natural gas during the majority of
the year and propane for a couple of weeks, that operator should only file an annual report for the natural
gas. If an operator has two pipeline segments with one pipeline segment used to transport natural gas and
the other pipeline segment transporting hydrogen gas, that operator should file two annual reports - 1
report for natural gas and 1 report for hydrogen gas.
6. Reserved
7. INTERstate andINTRAstate pipeline
For a given OPID, both INTERstate and INTRAstate pipeline facilities for a Commodity Group
can be entered in a single report. Enter each State and portion of the Outer Continental Shelf (OCS) for
both the INTERstate and INTRAstate pipeline facilities. The States and OCS options entered here create
the set of Parts H, I, J, K, L, M, P, Q, and R in the online reporting system. OCS options available for
selection are OCS – Alaska; OCS- Atlantic; OCS-Gulf of Mexico; and OCS – Pacific.
Interstate gas pipeline means a gas pipeline facility or that part of a gas pipeline facility that is used to
transport gas and is subject to the jurisdiction of the Federal Energy Regulatory Commission (FERC)
under the Natural Gas Act (15 U.S.C. 717 et seq.).
Intrastate gas pipeline means a gas pipeline facility or that part of a gas pipeline facility that is used to
transport gas within a state and is not subject to the jurisdiction of FERC under the Natural Gas Act
(15 U.S.C. 717 et seq.).

In Part L of this report, the number of HCA miles are reported by-State/OCS and by the
INTERstate/INTERstate status of the pipeline. All Part L data will be summed and displayed in Part B.

PART C - VOLUME TRANSPORTED IN TRANSMISSION PIPELINES (ONLY) IN MILLION
SCF PER YEAR (excludes Transmission lines of Gas Distribution systems)
Report the volume transported in transmission pipelines during the calendar year for this Commodity
Group, in millions of standard cubic feet (60ºF and 14.73 psia). Include the annual total volume
transported for all States and for all pipelines and/or pipeline facilities – both INTERstate or INTRAstate
– included within this OPID and for this Commodity Group. Volumes of any Commodity Group
transported in addition to the Commodity Group predominately transported through these pipeline
facilities should also be reported in Part C within the proper row. For gas transmission pipelines within
storage fields, report the volume moved out of storage. Do not report the volume placed into storage.
Note: This Part does not need to be completed if the reporting OPID includes only gathering pipelines or
if the transmission line is operated by a gas distribution company as an integral part of its distribution
pipeline system. Operators whose pipelines are limited to these types should select the box to so indicate.

PART D – MILES OF PIPE BY MATERIAL AND CORROSION PREVENTION STATUS
In Part P of this report, the miles of pipeline by material type and corrosion prevention status are reported
by-State/OCS and by the INTERstate/INTRAstate status of the pipeline. All Part P data will be summed

PART F – INTEGRITY INSPECTIONS CONDUCTED AND ACTIONS TAKEN
BASED ON INSPECTION
This Part incorporates transmission pipeline integrity management performance measure reporting
required by §192.945 and ASME/ANSI B31.8S, Section 9.4(b) (incorporated into the regulations by
reference), items 1-3. Report all integrity assessments (inspections) required by PHMSA’s IM regulations
which were conducted and actions which were taken during the calendar year based on inspection results.
Include all inspections conducted in the reporting period calendar year including baseline assessments and
re-assessments. When Part F specifies “WITHIN AN HCA SEGMENT”, report only on
transmission miles within HCA segments. Do not report on transmission pipelines included in an IM
Program as a result of Alternative MAOP under 192.620 or a PHMSA directive such as Corrective Action
Order, Compliance Order, or Special Permit. Part F is subdivided into six (6) sections.
Section 1 - Mileage inspected in calendar year using the following In-Line Inspection (ILI)
tools.
Report the mileage inspected using each of the listed tool types. Include total miles
inspected, not just the mileage in HCA. Where multiple ILI tools are used (e.g., a metal
loss tool and a deformation tool), report the mileage in both categories. Where a
combination tool is used (i.e., a single tool with multiple capabilities), report the mileage
separately in each category included as part of the combination. Thus, the total mileage
inspected during the calendar year (the sum of the mileage reported for individual tools)
may be greater than the actual number of physical pipeline miles on which ILI inspections
were run.
Section 2 - Actions taken in calendar year based on In-Line Inspections.
Include all actions taken during the calendar year that resulted from information obtained
during an ILI inspection, including actions taken as a result of ILI inspections conducted
during prior years. Do not include actions which are anticipated based on review of ILI
results but which did not actually occur during the reporting year.
Report in items a. and b. the total number of anomalies excavated and repaired based on
the operator’s repair criteria even if those criteria are different from (i.e., require repair of
damage more or less significant than) the repair criteria in IM regulations applicable to
anomalies in HCA pipeline segments.
Anomalies not excavated and eliminated by pipe replacement are reported in Parts F6d and
F6e.
Report in a. the total number of anomalies excavated, recognizing that multiple anomalies
may be exposed in a single excavation.
Report in b. only those anomalies actually repaired, not those for which other mitigative
actions, such as recoating, were taken.

Report in c. only the anomalies in HCA pipeline segments that were repaired and were
considered conditions under the repair criteria in the IM regulations. Scheduled
conditions, as used in c.4, refers to anomalies that are required to be repaired in accordance
with the schedule in ASME/ANSI B31.8S, section 7, Figure 4 (see §193.933(c)). The total
of repaired conditions reported in item c. may not exceed the total number of repaired
anomalies reported in item b.
Enter a value in each row, using zero (0) as appropriate. Leave no rows blank.
Section 3 – Mileage inspected and actions taken in calendar year based on Pressure Testing.
Report in a. total miles inspected by pressure testing, including both HCA mileage and
mileage outside HCA.
Report in b. the total number of test failures (ruptures and leaks) on all mileage tested
during the year.
Report in c. the ruptures and in d. the leaks repaired ONLY in HCA segments.
Section 4 – Mileage inspected and actions taken in calendar year based on DA (Direct
Assessment).
Include all actions taken during the calendar year that resulted from information obtained
through external corrosion direct assessment, internal corrosion direct assessment, and
stress corrosion cracking direct assessment inspections. Include all actions taken during
the calendar year that resulted from information obtained during a DA inspection,
including actions taken as a result of DA inspections conducted during prior years. Do not
include actions which are anticipated based on DA inspection results but which did not
actually occur during the reporting year.
Report in b. the total number of anomalies excavated and repaired, not those for which
other mitigative actions, such as recoating, were taken, within an HCA segment and
outside an HCA segment based on the operator’s repair criteria even if those criteria are
different from (i.e., require repair of damage more or less significant than) the repair
criteria in IM regulations applicable to anomalies in HCA pipeline segments.
Report in c. only the anomalies in HCA pipeline segments that were repaired and were
considered conditions under the repair criteria in the IM regulations. Scheduled
conditions, as used in c.4, refers to anomalies that are required to be repaired in accordance
with the schedule in ASME/ANSI B31.8S, section 7, Figure 4 (see §193.933(c)). The total
of repaired conditions reported in item c. may not exceed the total number of repaired
anomalies reported in item b.

Techniques.
IM regulations allow operators to use other assessment techniques provided that they
notify PHMSA (or states exercising regulatory jurisdiction) in advance. Report here the
mileage inspected and actions taken as a result of inspections conducted using any
technique other than those covered in Sections 1-4 of Part F. Describe the other
technique(s) in the “specify” field.
Include all actions taken during the calendar year that resulted from information obtained
during an inspection using an other technique including, actions taken as a result of
inspections conducted during prior years. Do not include actions which are anticipated
based on inspection results but which did not actually occur during the reporting year.
Report in b. only those anomalies actually repaired, not those for which other mitigative
actions, such as recoating, were undertaken.
Report in c. only the anomalies in HCA pipeline segments that were repaired and were
considered conditions under the repair criteria in the IM regulations. Scheduled
conditions, as used in c.4, refers to anomalies that are required to be repaired in accordance
with the schedule in ASME/ANSI B31.8S, section 7, Figure 4 (see §193.933(c)). The total
of repaired conditions reported in item c. may not exceed the total number of repaired
anomalies reported in item b.
Section 6 - Total Mileage Inspected (all Methods) and Actions Taken.
Items a. through c. will be calculated automatically based on data entered in sections 1-5.
Items d and e require information about actionable anomalies eliminated from HCAs by
pipe replacement and abandonment. An anomaly is considered actionable if it may exceed
acceptable limits, based on the operator’s anomaly and pipeline data analysis. Any
anomaly excavated and repaired should be reported in section 2, 4, or 5. Do not report
these anomalies again in items d and e. If pipeline facilities in an HCA were abandoned
and the operator replaced the transportation functionality with new pipeline facilities, enter
the anomalies in item d, replacement. If the transportation functionality of the abandoned
facility was NOT replaced by the operator, enter the anomalies in item e, abandonment.

PART G – MILES OF BASELINE ASSESSMENTS AND REASSESSMENTS COMPLETED IN
CALENDAR YEAR (HCA Segment miles ONLY)
Report the number of miles of pipeline in HCA that were assessed during the calendar year pursuant to
§192.921 or §192.937. Report separately the number of miles inspected for baseline assessments (e.g.,
initial baseline assessments and new baseline assessments, including those which occur due to new
pipelines or facilities, new HCA, etc.) and miles for which a reassessment was conducted. Do not include
pipelines or portions of pipelines that are not in an HCA but which are included in an IM Program as a

result of Alternative MAOP under 192.620 or a PHMSA directive such as Corrective Action Order,
Compliance Order, or Special Permit.
Report only assessments that were completed during the calendar year. An assessment is considered
complete on the date on which final field activities related to that assessment are performed, not
including repair activities. That is when a hydrostatic test is completed, when the last in-line inspection
tool run of a scheduled series of tool runs is performed, when the last direct examination associated with
direct assessment is made, or the date on which "other technology" for which an operator has provided
timely notification is conducted.
Operators should report in Part G the total number of miles actually assessed. This differs from Part F
where operators report the number of miles inspected by individual inspection methods and where some
mileage may be reported multiple times. Operators should validate the total completed and scheduled
assessment mileage in their Assessment Plans with the mileage reported here. The comparison of these
two numbers will highlight any discrepancies resulting from new HCA segments being added or deleted,
acquired or sold, or idled 1 or converted, and which need to be properly reflected in this Report.
For the designated Commodity Group, complete PARTs H, I, J, K, L, M, P, Q, and R covering
INTERstate pipeline facilities for each State and each Outer Continental Shelf (OCS) option in
which INTERstate systems exist within this OPID. Report offshore pipelines in state waters in the
State portion. Separately report offshore pipelines on the OCS under one of the four OCS options;
Alaska, Atlantic, Gulf of Mexico, and Pacific. Complete all of these Parts again forINTRAstate
pipeline facilities in each State in which INTRAstate systems exist within this OPID.
For example: Consider a gas pipeline system that includes INTERstate pipeline facilities in six
states and the Gulf of Mexico OCS and INTRAstate pipeline facilities in three states. These Parts
will be completed ten times; – seven times for INTERstate assets (once for each state and once for
OCS) and once for the INTRAstate assets in three states.
Each time these Parts are completed, the online reporting

Part J, by-decade installed, will serve as the mileage baseline gas transmission onshore, gas
transmission offshore, gas gathering onshore, and gas gathering offshore. When mileage for the
same set of pipelines is reported in different parts of the form, the online system will require the different
parts to be consistent. Mileage values over 60 miles must be within 0.5% of the baseline and values under
60 miles must be within 0.3 miles. For example, if you report 60 miles of offshore gas gathering by
decade of installation in Part J, the offshore gas gathering mileage by diameter in Part I must be within 0.3
miles of 60.
Part K will serve as the baseline for gas transmission miles by class location. When class location miles
are entered in Parts Q and R, the values must be consistent with those entered in Part K.

While the regulations do not recognize an intermediate state between operational and abandoned , PHMSA has acknowledged
that operators sometimes maintain some of their pipe in an idle status in
which conducting IM assessments is impractical.

PART H – MILES OF TRANSMISSION PIPE BY NOMINAL PIPE SIZE (NPS)
Report the miles of transmission pipe by Nominal Pipe Size (NPS) and location for both Onshore and
Offshore. Enter the appropriate mileage in the corresponding nominal size blocks. Only integers are used
for NPS. For example, report 6.625” diameter pipe in the NPS 6 category.
Pipe size which does not correspond to NPS measurements should be included in the “Other Pipe Sizes
Not Listed” columns. Include both the pipe size and the corresponding mileage.

PART I – MILES OF GATHERING PIPE BY NOMINAL PIPE SIZE (NPS)
Report the miles of gathering pipe by Nominal Pipe Size (NPS) and location for both Onshore and
Offshore. Report onshore Type A and Type B gathering lines (§192.8) separately. Enter the appropriate
mileage in the corresponding nominal size blocks. Only integers are used for NPS. For example, report
6.625” diameter pipe in the NPS 6 category.
Pipe size which does not correspond to NPS measurements should be included in the “Other Pipe Sizes
Not Listed” columns. Include both the pipe size and the corresponding mileage.

PART J – MILES OF PIPE BY DECADE INSTALLED
Report the miles of pipe by decade installed. When the decade of construction is unknown, enter
estimates of the totals of such mileage in the “Unknown” section of Part J.
PART K – MILES OF TRANSMISSION PIPE BY SPECIFIED MINIMUM YIELD STRENGTH
Class locations are defined in §192.5. Report the total miles of gas transmission pipe by hoop stress (as
percent of SMYS) for pipe onshore and offshore by stress range and Class Location. Report pipe for
which hoop stress is unknown and all non-steel pipe, regardless of operating pressure, in the rows
indicated.
Pay close attention to the classification of each pipeline. Short segments of pipeline operated by
distribution systems at less than or equal to 20 percent SMYS have sometimes been inaccurately reported
as transmission lines. Unless such pipelines meet the definition of transmission lines in §192.3, they
should be reported as distribution pipelines (Form PHMSA F 7100.1-1). If pipelines operating at less
than or equal to 20 percent SMYS meet the definition of transmission lines, they should be reported here.

Report the number of HCA miles for both Onshore and Offshore transmission pipe. Do not include
pipelines or portions of pipelines that are not in an HCA but which are included in an IM Program as a
result of Alternative MAOP under 192.620 or a PHMSA directive such as Corrective Action Order,
Compliance Order, or Special Permit.
HCA Mile data entered in this Part will be summarized in Part B and affects the ability to enter data in
Parts F and G.

PART M – INCIDENTS, FAILURES, LEAKS, AND REPAIRS
For the designated Commodity Group, this Part includes reporting for both pipeline facilities covered by
this OPID which are in HCAs as well as pipeline facilities that are not. Additional instructions are
provided below.

PART M1 – ALL LEAKS ELIMINATED/REPAIRED IN CALENDAR YEAR; FAILURES IN
HCA IN CALENDAR YEAR
This Part incorporates transmission pipeline integrity management performance measure reporting
required by §192.945 and ASME/ANSI B31.8S, Section 9.4(b)(4) (incorporated into the regulations by
reference), along with reporting of all leaks that has historically been part of the Annual Report.
Include all leaks repaired or eliminated including by replaced pipe or other component during the calendar
year. Operators with pipe segments in HCA should report separately the number of leaks repaired or
eliminated in HCA in the appropriate columns. All operators should report leaks for non-HCA pipe
segments, including all leaks on pipelines that contain no HCAs and all leaks in non-HCA locations on
pipelines in which HCAs exist. Do not include test failures.
Operators with pipe segments in HCA should also report the number of failures in HCAs, as required by
§192.945 and ASME/ANSI B31.8S, Section 9.4(b)(4).
Integrity management performance measures are not required for gathering pipelines. For gathering
pipelines, report only leaks. Report separately the number of leaks in Type A, Type B, and offshore
gathering pipelines.
Leaks are unintentional escapes of gas from the pipeline that are not reportable as Incidents under
§191.3. A non-hazardous release that can be eliminated by lubrication, adjustment, or tightening is not a
leak. Operators should report the number of leaks repaired based on the best data they have available.
For sections replaced and retired in place, operators should consider leak survey information to determine,
to the extent practical, the number of leaks in the replaced section.

NATURAL AND OTHER GAS TRANSMISSION AND GATHERING PIPELINE SYSTEMS

Failure is defined in ASME/ANSI B31.8S as a general term used to imply that a part in service: has
become completely inoperable, is still operable but is incapable of satisfactorily performing its intended
function; or has deteriorated seriously, to the point that it has become unreliable or unsafe for continued
use. Failures that result in an unintentional release of gas should be reported as leaks.
Incidents are defined in §191.3 and are reported on Form PHMSA F 7100.2.
For the purposes of this Part M1, Leaks and Failures are to be classified as one of the following:
EXTERNAL CORROSION: includes releases or failures in the pipe or other component due to
galvanic, bacterial, chemical, stray current, or other corrosive action initiating on the outside surface of
the pipe. This includes the “External Corrosion” sub-cause on the PHMSA Gas Transmission/Gathering
Incident Report form.
INTERNAL CORROSION: includes releases or failures in the pipe or other component due to
galvanic, bacterial, chemical, stray current, or other corrosive action initiating on the inside surface of the
pipe. This includes the “Internal Corrosion” sub-cause on the PHMSA Gas Transmission/Gathering
Incident Report form.
STRESS CORROSION CRACKING: includes releases or failures resulting from a form of
environmental attack of the pipe metal involving an interaction of a local corrosive environment and
tensile stresses in the metal resulting in formation and growth of cracks. This includes the
“Environmental Cracking-related” sub-cause on the PHMSA Gas Transmission/Gathering Incident
Report form.
MANUFACTURING: includes releases or failures caused by a defect or anomaly introduced during the
process of manufacturing the pipe, including seam defects and defects in the pipe body or pipe girth weld.
This includes the “Original Manufacturing Defect-related” sub-cause on the PHMSA Gas
Transmission/Gathering Incident Report form.
CONSTRUCTION: includes releases or failures caused by a dent, gouge, excessive stress, or some
other defect or anomaly introduced during the process of constructing, installing, or fabricating pipe (or
welds which are an integral part of pipe), including welding or other activities performed at the facility.
This includes the “Construction-, Installation-, or Fabrication-related” sub-cause on the PHMSA Gas
Transmission/Gathering Incident Report form.
EQUIPMENT: includes releases from or failures of items other than pipe or welds, and includes
releases or failures resulting from: malfunction of control/relief equipment including valves, regulators,
or other instrumentation; compressors or compressor-related equipment; various types of connectors,
connections, and appurtenances; the body of equipment, vessel plate, or other material (including those
caused by: construction-, installation-, or fabrication-related and original manufacturing-related defects or
anomalies; and low temperature embrittlement); and, all other equipment-related releases or failures. This
includes all of the sub-causes under G6, Equipment Failure, on the PHMSA Gas Transmission/Gathering
Incident Report form.

as defined in 30 USC 185.
Enter all leaks repaired, eliminated, or scheduled for repair during the reporting year, excluding those
reported as incidents on Form PHMSA F 7100.2.

PART P – MILES OF PIPE BY MATERIAL AND CORROSION PREVENTION STATUS
For steel pipe, report the total miles of onshore and offshore transmission and gathering pipe that is
cathodically protected and cathodically unprotected subdivided, in each case, into the amount that is bare
and the amount that is coated pipe. COATED means pipe coated with an effective hot or cold applied
dielectric coating or wrapper. For non-steel pipe, report the total miles of onshore and offshore pipe for
each type listed.
Composite means pipe consists of two or more dissimilar materials layered together to be stronger than
the individual materials. Use of composite pipe requires a PHMSA Special Permit or waiver from a State.
Examples include, but are not limited to, fiber reinforced thermoplastic composite pipe, fiber reinforced
thermosetting plastic pipe, steel reinforced thermoplastic pipe, and metallic composite pipe. If a
dissimilar material has been inserted into older pipe, report the pipe as the material that contains the
pressure.
Other means a pipe made of a material not specifically designated on the form, such as copper,
aluminum, etc. Describe the other material(s) in the “specify” field.
PART Q – Gas Transmission Miles by § 192.619 MAOP Determination Method
In the “Total” columns, operators report transmission pipeline miles by the subsection of § 192.619
serving as the limiting factor for establishing MAOP and by each combination of class location and HCA.

A short explanation of each § 192.619 subsection for MAOP determination methodology is:
§ 192.619

Methodology Description

(paragraph)

(a)
(a)(1)
(a)(2)
(a)(3)
(a)(4)
(c)
(d)
Other

Introduction: Except as specified in (c) and (d), use the lowest MAOP determined
by (a)(1), (a)(2), (a)(3), (a)(4).
Design Pressure
Post-Construction Pressure Test
High Actual Operation Pressure (5 years preceding 1970)
History of Pipe (primarily corrosion and actual operating pressure)
Allows the use of (a)(3) even if MAOP is higher than MAOPs determined by other
methodologies in (a)
Alternative MAOP (§ 192.620)
Use this category if you did not base your MAOP on any of the paragraphs within
§ 192.619

A short explanation of each Class Location and HCA is:
Location
Class 1
Class 2
Class 3
Class 4
High
Consequence
Area (HCA)

Short Description (full detail in § 192.5)
≤10 buildings intended for human occupants.
<46 and >10 buildings intended for human occupants.
≥46 buildings or an area within 100 yards of building/well defined area
occupied by at least 20 persons at designated intervals.
Any location where buildings with four or more stories above ground are
prevalent.
A location which is specifically defined in § 192.903. In general, a HCA is
an area where a pipeline release could have greater consequence to human
health and safety or the environment.

Transmission miles may only be entered under a single subsection of § 192.619. In some scenarios,
192.619(a)(1) through (4) may all have been considered when establishing MAOP, but PHMSA expects
that one value is lower than the others and was used to establish MAOP. In other scenarios, 192.619(c)
could be used to set MAOP, regardless of the values in 192.619(a)(1) through (4). For each combination
of class location and HCA shown on the form, report the miles in each MAOP category. The sum of all
“Total” columns for 192.619 subsections and Other for each class location must be consistent with the
class location data reported in Part K. If miles are entered in the Other column, enter text describing the
Other method(s) used to establish MAOP.
For each combination of class location and HCA, except Classes 1 and 2 outside HCAs, report the
transmission miles for which the operator lacks complete records to verify the MAOP in the “Incomplete
Records” column. The value in the “Incomplete Records” column must be less than or equal to the value
in the “Total” column for each combination of class location and HCA. For the purpose of this part,
“verification records” are records that can be used to validate the MAOP for the subject pipelines such as:
as-built drawings, alignment sheets, specifications, and all design, construction, inspection, testing,

maintenance, manufacturer, or other related documents. These records should be traceable, verifiable,
and complete. For miles of transmission pipeline for which the operator has not completed the records
review, include these miles in the “Incomplete Records” column. See PHMSA Advisory Bulletin (ADB)
2012-06 for additional
details: http://www.phmsa.dot.gov/staticfiles/PHMSA/DownloadableFiles/Pipeline/Regulations/Advisory
Bulletins/AD-12-06.pdf
When reporting transmission miles for which 192.619(d) was used to establish MAOP, include miles of
pipeline installed pursuant to a PHMSA special permit allowing operation up to 80% SMYS in Class 1
areas. From 2006 through 2010, PHMSA issued fifteen of these special permits with conditions
equivalent to pipeline installed under 192.619(d).

PART R - Gas Transmission Miles by Pressure Test (PT) Range and Internal Inspection
For Part R, enter miles of gas transmission pipe in each of the three pressure test ranges with each range
divided into miles able to be internally inspected and miles unable to be internally inspected. All gas
transmission miles must be reported in this part. The miles entered for each class location must be
consistent with the class location data entered in Part K.
If an operator is uncertain whether a gas transmission pipeline has been subjected to a post-construction
pressure test, report the miles in the “PT < 1.1 or No PT” section.
“Miles Internal Inspection ABLE” means a length of pipeline through which commercially available
devices can travel, inspect the entire circumference and wall thickness of the pipe, and record or transmit
inspection data in sufficient detail for further evaluation of anomalies. If an operator is uncertain whether
a gas transmission pipeline is able to be internally inspected, report the miles in the “Miles Internal
Inspection NOT ABLE” column.
For the designated Commodity Group, complete Part N one time for all of the pipeline facilities
included within this OPID. Complete Part O one time for all the pipeline facilities included within
this OPID if any Part L HCA mile value is greater than zero.
PART N – PREPARER SIGNATURE
The Preparer is the person who compiled the information and prepared the responses to the Report. Enter
the Preparer’s name, title, e-mail address, phone number. PHMSA will contact the Preparer if data
quality checks raise questions about the report.
PART O – CERTIFYING SIGNATURE
CERTIFYING SIGNATURE must be a senior executive officer of the operator. The Pipeline
Inspection, Protection, Enforcement and Safety Act (49 U.S.C. 60109(f)) requires pipeline operators to
have a senior executive officer of the company sign and certify annual pipeline Integrity Management

Program (IMP) performance reports - portions of Parts M1, F, G, and L. By this signature, the senior
executive officer is certifying that he or she has (1) reviewed the Report and (2) to the best of his or her
knowledge, believes the Report is true and complete. Entering the senior executive officer’s name onto
the electronic Report is equivalent to a paper submission and has the same legal authenticity and
requirements.
