[Docket No. PHMSA-2016-0002]
RIN 2137-AF13

Pipeline Safety: Periodic Updates of Regulatory References to
Technical Standards and Miscellaneous Amendments

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA),
DOT.

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: PHMSA is proposing to incorporate by reference more than 20
consensus standards into the Federal pipeline safety regulations. This
notice of proposed rulemaking (NPRM) would incorporate by reference a
new, updated, or reaffirmed edition of each consensus standard. This
NPRM would also make non-substantive corrections to clarify regulatory
language in certain provisions. These editorial changes are minor and
would not require pipeline operators to undertake new pipeline safety
initiatives.

DATES: Persons interested in submitting comments on this NPRM must do
so by March 16, 2021.

I. Background

A. History of Incorporation by Reference

    Voluntary consensus standards are technical standards developed or
adopted by domestic and international standards development
organizations (SDOs). These organizations use agreed-upon procedures to
update and revise their published standards every three to five years
to reflect modern technology and best technical practices.
    The National Technology Transfer and Advancement Act of 1995
(NTTAA) (Pub. L. 104-113; March 7, 1996) directs Federal agencies to
use voluntary consensus standards and design specifications developed
by voluntary consensus standard bodies instead of government-developed
voluntary technical standards when appropriate. The Office of
Management and Budget (OMB) Circular A-119: Federal Participation in
the Development and Use of Voluntary Consensus Standards and in
Conformity Assessment Activities sets the policy for Federal use and
development of voluntary consensus standards.\1\
---------------------------------------------------------------------------

    \1\ OMB (February 10, 1998), Federal Participation in the
Development and Use of Voluntary Consensus Standards and in
Conformity Assessment Activities (Circular No. A-119). Retrieved
from: https://www.whitehouse.gov/wp-content/uploads/2017/11/Circular-119-1.pdf.
---------------------------------------------------------------------------

    Material that is incorporated by reference (IBR) is treated as if
it was published in the Federal Register and the CFR. Therefore, like
any other rule issued in the Federal Register, a voluntary consensus
standard that has been incorporated by reference has the force and
effect of law. Congress authorized incorporation by reference to reduce
the volume of material published in the Federal Register and the CFR
(see 5 U.S.C. 552(a) and 1 CFR part 51) and granted authority to the
Director of the Federal Register to determine whether a proposed IBR
serves the public interest. Unless expressly provided otherwise in a
regulation, if a provision of a standard incorporated by reference
conflicts with a regulation, the regulation takes precedence.
    New or updated pipeline standards often incorporate new
technologies, materials, management practices, and other innovations
that improve the safety and operations of pipelines and pipeline
facilities. Because the Federal pipeline safety regulations (PSRs),
located in 49 CFR parts 190-199, involve a great deal of technical
subject matter, PHMSA has incorporated by reference more than 80
standards and specifications into the regulations. PHMSA regularly
reviews newer editions of currently referenced consensus standards and
issues regulations to incorporate by reference updated standards where
appropriate. This ensures that the PSRs incorporate and facilitate use
of the latest safety innovations and materials. In addition to the
improvements in the documents themselves, adopting more recent editions
of consensus standards prevents conflicts with other standards
operators and suppliers may be complying with voluntarily and avoids
confusion that can arise when standards required by the regulations are
out of date. The lists of publications that PHMSA has incorporated by
reference into part 192 (regulating the transportation of natural gas
and other gas by pipeline) and 195 (regulating the transportation of
hazardous liquids by pipeline) are found at Sec. Sec.  192.7 and 195.3,
respectively.
    PHMSA employees participate in 25 national SDOs that address the
design, construction, maintenance, inspection, operation, and repair of
pipeline facilities. These subject matter experts represent the agency
and participate in discussions and technical debates, register
opinions, and vote in accordance with the procedures of the standards
body at each stage of the

standards development process (unless prohibited from doing so by law).
PHMSA participates in this process to ensure that the agency's safety
priorities are considered and to avoid the need to develop separate,
government-unique standards. PHMSA's participation does not imply that
the agency agrees with or endorses all decisions reached by such
organizations. PHMSA adopts only those portions of consensus standards
that adequately protect public safety and the environment.
    PHMSA periodically undertakes a rulemaking to IBR updated consensus
standards. The standards proposed in this rulemaking have been reviewed
by PHMSA personnel and are considered appropriate to incorporate into
the CFR. Previous updates to incorporate consensus standards by
reference were published on August 6, 2015 (80 FR 46847 (correction)),
January 5, 2015 (80 FR 168), August 11, 2010 (75 FR 48593), February 1,
2007 (72 FR 4655 (correction)), June 9, 2006 (71 FR 33402), June 14,
2004 (69 FR 32886), February 17, 1998 (63 FR 7721), and May 24, 1996
(61 FR 26121).

B. Availability of Materials to Interested Parties

    PHMSA currently incorporates by reference into parts 192, 193, and
195 all or parts of more than 80 standards and specifications developed
and published by SDOs. In general, SDOs update and revise their
published standards every two to five years to reflect modern
technology and best technical practices. ASTM International (ASTM,
formerly the American Society for Testing and Materials) often updates
some of its more widely used standards every year. Sometimes, multiple
editions are published in a given year.
    In accordance with the NTTAA, PHMSA has the responsibility for
determining which standards should be added, updated, or removed. PHMSA
handles revisions to materials incorporated by reference in the PSRs
via the rulemaking process, which allows the public and regulated
entities the opportunity to provide input. During the rulemaking
process, PHMSA must also obtain approval from the Office of the Federal
Register to make changes regarding materials incorporated by reference.
    Pursuant to Section 24 of the Pipeline Safety, Regulatory
Certainty, and Job Creation Act of 2011, Public Law 112-90, 49 U.S.C.
60102(p), as amended, ``the Secretary may not issue a regulation
pursuant to this chapter that incorporates by reference any documents
or portions thereof unless the documents or portions thereof are made
available to the public, free of charge.'' On November 7, 2014, the
Office of the Federal Register issued a final rule that revised 1 CFR
51.5 to require that Federal agencies ``discuss, in the preamble of the
proposed rule, the ways that the materials it proposes to incorporate
by reference are reasonably available to interested parties or how it
worked to make those materials reasonably available to interested
parties'' (79 FR 66267).
    To meet the requirements of Section 24, PHMSA negotiated agreements
with all but one of the SDOs with standards incorporated by reference
in the PSRs to make viewable copies of those standards available to the
public at no cost. The organizations that agreed to the requirements of
Section 24 are: The American Petroleum Institute (API), the American
Gas Association (AGA), ASTM, the Gas Technology Institute (GTI), the
Manufacturers Standardization Society of the Valve and Fittings
Industry, Inc. (MSS), NACE International (NACE), and the National Fire
Protection Association (NFPA). As of the date of publication, PHMSA was
not able to reach an agreement with the American Society of Mechanical
Engineers (ASME). Each organization's mailing address and website is
listed in 49 CFR parts 192, 193 and 195.
    In addition, PHMSA will provide temporary access to any standard
which is incorporated by reference or proposed for incorporation. To
gain temporary access to standards, including those from ASME, please
email<EMAIL_ADDRESS>with your request. You must include your
phone number and physical address, and an email address where we should
send a response. PHMSA will respond within five business days and
provide access to the standard.

II. Summary of Standards Incorporated by Reference Proposed To Be
Updated

    This list includes the title of each standard affected by this
NPRM, the edition PHMSA proposes to incorporate, a summary of the
standard, the previously incorporated version (if applicable), and the
sections in the CFR where the standards are referenced. The omission of
a new edition of a standard in this NPRM does not imply that PHMSA has
reviewed and rejected that document. In this NPRM, PHMSA proposes to
incorporate the following updated editions of technical standards
currently incorporated by reference in parts 192 and 195:

A. American Petroleum Institute (API)

1. API Recommended Practice 651, Cathodic Protection of Aboveground
Petroleum Storage Tanks
    PHMSA proposes to incorporate by reference API Recommended Practice
(RP) 651, ``Cathodic Protection of Aboveground Petroleum Storage
Tanks,'' 4th edition, September 2014 into Sec. Sec.  195.565 and
195.573(d). Cathodic protection is a method of protecting metallic
pipelines from corrosion. This RP contains: (1) Procedures and
practices for effective corrosion control on aboveground storage tank
bottoms using cathodic protection; (2) provisions for the application
of cathodic protection to existing and new aboveground storage tanks;
and (3) information and guidance for cathodic protection specific to
aboveground metallic storage tanks in hydrocarbon service.
    The amendments in the 4th edition of API RP 651 are primarily minor
technical improvements and editorial revisions. These improvements
include more specific details throughout and more conservative
consideration of cathodic protection based on pad material, product
temperature, and tank size. These corrosion-control-requirement updates
improve safety and the clarity and technical accuracy of the document.
    [Replaces IBR: ANSI/API Recommended Practice 651, ``Cathodic
Protection of Aboveground Petroleum Storage Tanks,'' 3rd edition,
January 2007, (ANSI/API RP 651).]
2. API Recommended Practice 2026, ``Safe Access/Egress Involving
Floating Roofs of Storage Tanks in Petroleum Service''
    PHMSA is proposing to incorporate API RP 2026, ``Safe Access/Egress
Involving Floating Roofs of Storage Tanks in Petroleum Service,'' 3rd
edition, June 2017 into Sec.  195.405(b). The 3rd edition of API RP
2026 (formerly API Publication 2026) addresses the hazards associated
with access/egress onto external and internal floating roofs of in-
service petroleum storage tanks. In a floating roof tank, the roof
floats on top of product in the tank and rises and lowers with the
level of product in the storage tank. Floating roofs minimize the
creation of hazardous vapors above the product. A floating roof can be
designed for use on a tank with no fixed roof (an external floating
roof) or inside a tank with a fixed roof (internal floating roof).
    Work tasks requiring access to floating roofs poses unique safety
hazards to maintenance personnel. These include

confined space hazards, hazardous atmospheric conditions such as
flammable or toxic vapors, and various physical hazards depending on
the design and condition of the tank. The document identifies a number
of these potential hazards and prescribes practices, procedures, and
tests, which are required to mitigate these hazards and perform work
safely. In the regulations, operators are required to use API RP 2026
to consider the hazards associated with performing maintenance on in-
service hazardous liquid storage tanks and identify applicable
hazardous conditions, safety practices, and procedures in their
procedure manual.
    The 3rd edition of API RP 2026 includes several minor, primarily
editorial updates. These include minor revisions to the definitions,
eliminating references to NFPA 70 and NFPA 325M, changes to terminology
such as replacing the phrase ``lower flammable limits'' to the phrase
``lower explosive limits,'' and additional clarifications to conditions
in Section 7.1.4. The clarified conditions include atmospheric,
working, tank service, operating, product loading, and physical
conditions. In general, these clarifications mean that individuals must
make sure hazards are addressed and potential sources of hazards or
vapor ignition have been properly secured before they go onto a tank
floating roof. These minor changes improve the usability of the
document.
    [Replaces IBR: API Publication 2026, ``Safe Access/Egress Involving
Floating Roofs of Storage Tanks in Petroleum Tanks,'' 2nd edition,
April 1998 (Reaffirmed June 2006).]
3. API Specification 5L, Specification for Line Pipe
    PHMSA is proposing to incorporate by reference API Specification
(Spec) 5L, ``Specification for Line Pipe,'' 46th edition, April 2018,
including Errata 1 (May 2018) into Sec. Sec.  192.55(e); 192.112(a),
(b), (d), (e); 192.113; Item I, Appendix B of part 192; and 195.106(b)
and (e). API Spec 5L is the primary manufacturing specification for
seamless and welded steel pipe for use in both gas and hazardous liquid
pipeline transportation systems. The specification does not cover cast
pipe and non-steel pipe. The specification includes requirements for
pipe material, manufacturing, quality control and testing, inspection,
and pipe marking.
    The 46th edition of API Spec 5L includes slightly strengthening the
pipe end straightness tolerance requirement from 4 mm maximum of
deflection within 1 meter of each end to 3.2 mm maximum of deflection
within 1.5 meters of each end, and clarifies how to define and measure
end-squareness. Additionally, it includes some editorial revisions
consistent with changes to API style guidelines.
    The specification also contains two new annexes: (1) Annex M--
Specification for Welded Jointers and (2) Annex N--Pipe Ordered for
Applications Requiring Longitudinal Plastic Strain Capacity. Annex M
adds requirements for pipe manufacturers making welded jointers, which
are short pieces of pipe welded together to form one joint. Welded
jointers are similar to double jointing except that typically double
jointing is not done by the manufacturer. Before this annex, 5L had no
requirements for testing the jointed welds nor how they should be
marked. Annex N adds baseline requirements for pipe manufactured for
strain-based design (SBD) projects. SBD is used for pipelines that may
see high levels of strain due to pipe movement from geotechnical
forces; few onshore pipelines in the continental United States see
these strains and instead use conventional stress-based design. Part
192 does not permit SBD, except under special permit; however, the new
annexes do enhance pipeline safety under the circumstances to which
they are applicable.
    [Replaces IBR: API Specification 5L, ``Specification for Line
Pipe,'' 45th edition, July 2013, (ANSI/API Spec 5L).] \2\
---------------------------------------------------------------------------

    \2\ On May 1, 2019, PHMSA issued a notice to natural gas and
hazardous liquid pipeline operators alerting them that PHMSA would
exercise enforcement discretion if an operator did not comply with
API Specification 5L, 45th edition, provided that the operator could
``demonstrate compliance with the more stringent provisions of API
Spec 5L, 46th edition, April 2018, including Errata 1 (May 2018).''
[https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/docs/standards-rulemaking/pipeline/71236/stay-enforcement-api-specification-5l.pdf]. PHMSA indicated in the notice of enforcement discretion
that it was intended to remain in effect until PHMSA took final
action on incorporating the 46th edition in a rulemaking. A copy of
the notice of enforcement discretion is included in the docket.
---------------------------------------------------------------------------

4. API Specification 6D, Specification for Pipeline and Piping Valves
    PHMSA is proposing to incorporate API Specification (Spec) 6D,
``Specification for Pipeline and Piping Valves,'' 24th edition, August
2014, including Errata 1 (October 2014), Errata 2 (December 2014),
Errata 3 (February 2015), Errata 4 (June 2015), Errata 5 (July 2015),
Errata 6 (September 2015), Errata 7 (June 2016), Errata 8 (August
2016), Errata 9 (March 2017), Addendum 1 (March 2015), and Addendum 2
(June 2016) into Sec. Sec.  192.145(a) and 195.116(d). API Spec 6D
defines the design, manufacturing, assembly, testing, and documentation
requirements for valves used in pipeline systems. PHMSA requires all
valves on gas pipeline systems, other than those made of cast-iron or
plastic, to meet the requirements of API Spec 6D or a national or
international standard that provides an equivalent performance level.
Liquid pipeline valves must be shell-tested and seat-tested in
accordance with API Spec 6D.
    The valve shell test or body test is conducted based on the valve
manufacturer's approved test procedure and Section 9.3 of API Spec 6D.
In the valve shell test, the valve ends are closed and the valve is put
in a partially open position. The valve body is hydrostatically tested
with a test pressure of at least 1.5 times the pressure rating of the
valve body. The result of the test is satisfactory if no visible leak
is observed from the valve body, packing gland, or elsewhere. This test
ensures that the valve body will not fail and leak product into the
surrounding environment at the pressure rating.
    The valve seat leak test is performed after successful completion
of valve shell test. During this test, the valve is completely closed.
The inlet of the valve is hydrostatically tested with a test pressure
of at least 1.1 times the pressure rating of the valve. The valve
passes the seat test if the measured leakage does not exceed the
maximum values in section 9.4.3 of the standard. Block valves must be
seat tested for each intended fluid flow direction. This test ensures
that a block valve will adequately stop the flow of product through the
valve when it is closed.
    The 24th edition of API Spec 6D includes several clarifications,
safety improvements, and editorial revisions. Safety improvements
include clarified bore tolerance specifications for full-opening
valves,\3\ and new procedures for installers when no minimum bore
tolerances are listed in the specification. Additionally, the 24th
edition prohibits designing flanged valves with intermediate pressure
ratings. The flanges used to connect such valves to other components
have standardized pressure specifications. Prohibiting flanged valves
with an intermediate pressure rating avoids potentially dangerous
situations, like transferring such a valve to an application with
pressure that is within the design limits

of the standard flanges, but exceeds the pressure rating of the valve
to which the flanges are attached. Other improvements include adding a
requirement that valve body and cover components be chosen based on the
pressure-temperature rating of the material used, and requirements for
valve cavity pressure relief devices.
---------------------------------------------------------------------------

    \3\ A full opening valve is designed with an opening that is
unobstructed when the valve is in the open position. The opening
must be not smaller than the inside diameter of the end connections.
The bore refers to the minimum inside diameter of valve, including
the size of the opening.
---------------------------------------------------------------------------

    The 24th edition also includes new guidance and clarification
regarding calibration, marking, and documentation requirements. The
calibration provisions were updated to specify that calibration
intervals should not exceed one year. The marking provisions were
updated to provide more detailed information regarding the location,
letter size, and the use of name plate markings for the smaller valves.
Also, the provisions on the information that is provided with each
valve were updated to include additional information that may be useful
for installers, operators, and inspectors.
    [Replaces IBR: ANSI/API Specification 6D, ``Specification for
Pipeline Valves,'' 23rd edition, October 1, 2008, including Errata 1
(June 2008), Errata 2 (November 2008), Errata 3 (February 2009), Errata
4 (April 2010), Errata 5 (November 2010), Errata 6 (August 2011)
Addendum 1 (October 2009), Addendum 2 (August 2011), and Addendum 3
(October 2012), (API Spec 6D).]
5. API Standard 620, Design and Construction of Large, Welded, Low-
Pressure Storage Tanks
    PHMSA proposes to incorporate by reference API Standard (Std) 620
``Design and Construction of Large, Welded, Low-Pressure Storage
Tanks,'' 12th edition, October 2013, including Addendum 1 (November
2014) into Sec. Sec.  195.132 (b)(2); 195.205(b)(2); 195.264(b)(1);
195.264(e)(3); 195.307(b); 195.565; and 195.579(d). API Std 620
specifies design, construction, and testing requirements for large,
field assembled, welded steel tanks used to store petroleum, petroleum
products, or other liquids used in the petrochemical industry. Tanks
designed, constructed, and tested in accordance with API Std 620 are
rated to operate with a vapor pressure up to 15 psig and a metal
temperature below 250 [deg]F.
    The primary benefit of incorporating the 12th edition involves
incorporating new materials and designs. These revisions include
revised requirements for seismic loading design standards and more
stringent design and testing standards for refrigerated tank systems.
Specifically, the outer shell of double wall tanks must now meet most
material and design requirements applicable to the inner shell of
refrigerated tanks. Hazardous liquid breakout tanks typically do not
require refrigeration and requirements for liquefied natural gas plants
in part 193, including standards for refrigerated tanks, are being
considered in a separate rule. Finally, the 12th edition adds standards
for steel mixed materials storage tanks and duplex stainless-steel
storage tanks, which were not previously included in the standard.
    [Replaces IBR: API Standard 620, ``Design and Construction of
Large, Welded, Low-pressure Storage Tanks,'' 11th edition, February
2008, including addendum 1 (March 2009), addendum 2 (August 2010), and
addendum 3 (March 2012), (API Std 620).]
6. API Standard 650, Welded Tanks for Oil Storage
    PHMSA is proposing to incorporate API Std 650, ``Welded Tanks for
Oil Storage,'' 13th edition, March 1, 2020, into Sec. Sec.  195.132(b);
195.205(b); 195.264(b), (e); 195.307(c) and (d); 195.565; and
195.579(d). This standard establishes minimum requirements for
material, design, fabrication, erection, and inspection for vertical,
cylindrical, aboveground, closed- and open-top, welded storage tanks in
various sizes and capacities for internal pressures approximating
atmospheric pressure. This standard applies only to tanks whose entire
bottom is uniformly supported and to tanks in non-refrigerated service
that have a maximum design temperature of 93[deg]C (200 [deg]F) or
less. In part 195, breakout tanks associated with the transportation of
hazardous liquids that are included in the scope of this standard must
be designed, constructed, tested, and repaired in accordance with API
Std 650.
    Many of the changes since the 11th edition of API Std 650 result in
enhanced safety. The standard strengthens anchoring requirements by
increasing the criteria required to allow a tank to be unanchored and
requiring that more welds be examined. In addition, the revised
standard contains provisions for considering snow loading on floating
roofs to account for increases in internal pressures. Other changes are
editorial; for example, throughout the standard, the term
``inspection'' is changed to ``examination'' when referring to NDE.
These revisions improve the clarity and technical accuracy of the
document.
    However, there are sections of the revised standard that may
provide a smaller factor of safety than the 11th edition. For example,
in the revised standard, the factor used in equations to calculate how
high the product in the tank may slosh around during a seismic event in
Equation E.7.2-1 changes from 0.5 to 0.42, which is less conservative.
Seismic design is not always required in the CFR, but Annex E (Seismic
Design of Storage Tanks) must be applied if seismic design is requested
by the operator. This revision lowers the minimum freeboard (the space
in the tank between maximum operating level of the product and the
maximum possible product level) specifications for tanks designated by
the operator as Seismic Use Group (SUG) \4\ III or tanks designated as
SUG II in areas with higher potential vertical acceleration (see Table
E.7). Most breakout tanks would be classified as SUG I, where minimum
freeboard specifications are recommended but not required. As described
in EC.7.2 in the standard, damage to the roof due to sloshing is very
unlikely to cause a structural failure of the tank itself; the primary
consequences of sloshing damage are the potential for an interruption
of operations, repair costs, or, if the roof fails, a small release
into secondary containment. This change is also offset by other
improvements in the revised standard, including more conservative
vertical acceleration parameter in E.6.1.3 (Vertical Seismic Effects).
The revised standard sets a parameter value at the maximum of what was
previously a range of values.
---------------------------------------------------------------------------

    \4\ Seismic Use Groups (SUGs) are defined in API Std 650 at EC.3
and are used to classify tanks by the potential consequences of
failure during a seismic event. Tanks designated as SUG III or SUG
II serve public safety or public welfare functions, or pose a hazard
to the public and lack secondary containment. SUG I is the default
classification and includes most tanks with secondary containment
and tanks without containment located in a terminal or industrial
area away from public access.
---------------------------------------------------------------------------

    The majority of the changes in the 13th edition of the standard are
editorial and do not substantially change or effect safety. Additional
changes include adding new requirements for anchor nuts and bolts;
further refining the process for design wind speeds, pressures, and
loads; specifying which weld pass (inside/outside) may be applied for
various examination methods; further broadening hydrotest requirements;
and adding an allowance for the minimum number of inspection hatches to
be based on the size of a given tank.

11th edition, June 2007 (effective February 1, 2012), includes addendum
1 (November 2008), addendum 2 (November 2009), addendum 3 (August
2011), and errata (October 2011), (API Std 650).]

7. API Standard 1104, Welding of Pipelines and Related Facilities
    PHMSA is proposing to incorporate by reference API Std 1104,
``Welding of Pipelines and Related Facilities'' 21st edition, September
2013, including Errata 1 (April 2014), Errata 2 (June 2014), Errata 3
(July 2014), Errata 4 (November 2015), Errata 5 (September 2018),
Addendum 1 (July 2014), and Addendum 2 (May 2016) into Sec. Sec.
192.225(a); 192.227(a); 192.229(c); 192.241(c); Item II of Appendix B
to part 192; 195.214(a); 195.222(a) and (b); and 195.228(b). API Std
1104 is the primary standard for welding steel piping and for testing
welds on steel pipelines. It covers the requirements for welding and
nondestructive testing of pipeline welds. In the PSRs, this standard is
used for qualifying welders, welding procedures, and welding operators,
and interpreting the results of non-destructive tests.
    The most significant revisions in the 21st edition of API Std 1104
include safety improvements to sections that are incorporated by
reference into the regulations. In Section 5, which addresses welding
procedures for processes using filler metals, the updates include:
Requirements that electrical characteristics be specified for each
specific type and size of electrode, rod, or wire; specifications
regarding when and how forced cooling of a recently completed weld can
be performed; a new requirement to consider the mechanical
compatibility of filler metals; a new requirement to specify the
electrode manufacturer and trade name for certain types of shielded
metal arc welding electrodes; and modified criteria that allow
acceptance of tensile tests if the specimen breaks outside the weld and
heat-affected-zone at a value not less than 95 percent of the specified
minimum tensile strength of the pipe material.
    The 21st edition revises Section 6 to allow ultrasonic testing of
welds used for welder qualification. Although Section 10 is not used in
the PSRs, it is greatly expanded in the 21st edition to provide more
information on repairing welds. The revisions to Section 12 include
documentation enhancements like those in Section 5 and a requirement to
perform a nick-break test \5\ for procedures that include manual or
semi-automatic passes. The addition of nick-break tests helps ensure
that mechanized welds made with manually deposited passes will meet the
workmanship requirements in API 1104.
---------------------------------------------------------------------------

    \5\ A nick-break test is a destructive test for evaluating the
quality of a weld. In the test, a weld specimen is prepared and then
fractured. The exposed surface is then visually examined for weld
imperfections.
---------------------------------------------------------------------------

    In addition, the 21st edition adds guidance to both Appendix A and
Appendix B. The 21st edition of Appendix A modifies essential variables
to better quantify the variability of welding electrodes and pipe
materials, clarifies acceptance criteria for tensile tests, and adds a
requirement to verify production welding is performed within the
parameters of the qualified welding procedure via a quality control
program. The 21st edition of Appendix B adds guidance on making in-
service welds and expands the section to cover weld deposition pipe
repair.
    The 21st edition also allows a welder qualified in a fixed position
to be qualified for the roll position. Welder qualification in the
fixed position requires demonstration of welding skills in multiple
positions around a stationary pipe. During roll welding, the welder
only welds in one position while the pipe rotates and the welder must
only demonstrate welding skills in one position. Since a welder
qualified in a fixed procedure has demonstrated the skills necessary to
weld in multiple positions, this change has no effect on safety and
eliminates duplicative qualification requirements.

8. ANSI/API Standard 2000, Venting Atmospheric and Low-Pressure Storage
Tanks
    PHMSA is proposing to incorporate by reference API Std 2000,
``Venting Atmospheric and Low-pressure Storage Tanks,'' 7th edition,
March 2014, into Sec.  195.264(e)(2) and (e)(3). This standard contains
vapor-venting requirements for aboveground liquid petroleum products
storage tanks and aboveground and/or underground refrigerated storage
tanks, all of which are designed for operation at pressures from full
vacuum through 103.4 kPa (or 15 psig). Normal vapor venting refers to
the inflow and outflow of vapor related to pressure changes inside the
storage tanks. Emergency vapor venting relates to the inflow or outflow
of vapor that may occur due to unforeseen circumstances. Vapor-venting
requirements deal with the operation of vapor vents in response to
temperature and pressure changes both inside and outside of a tank.
Pressure normally accumulates inside most production or breakout
storage tanks that contain various types of hazardous liquid. The new
edition of this standard provides more information on equipment that
stabilizes pressure within the tank by venting or depressurizing once
the pressure within the tank reaches a certain level. The vapor-venting
requirements in this standard elaborate on pipeline owners'
obligations, including providing vapor-venting equipment guidelines.
    The 7th edition of API Std 2000 contains several minor revisions
since the currently incorporated 6th edition. These include greater in-
breathing and out-breathing calculation requirements, modified
reduction factor for double-wall tanks, and eliminating the need to
calculate evaporation rates. The 7th edition also includes more
stringent requirements to ensure that vapor releases from relief
devices and vents do not create hazards for nearby workers, equipment,
or structures. These requirements increase safety by not allowing the
accumulation of potentially flammable vapors at grade level or in
enclosed spaces, and the new requirements for vapor releases from
relief devices and vents provide greater protection for workers and
properties during venting operations.

9. API Standard 2350, Overfill Prevention for Storage Tanks in
Petroleum Facilities
    PHMSA proposes to incorporate by reference API Standard (Std) 2350,
``Overfill Prevention for Storage Tanks in Petroleum Facilities,'' 5th
edition, September 1, 2020, into Sec.  195.428(c). This standard is
intended for storage tanks associated with facilities that receive
flammable and combustible petroleum liquids, such as refineries,
marketing terminals, bulk plants, and pipeline terminals. It addresses
minimum overfill and damage-prevention practices for aboveground
storage tanks in petroleum facilities, including refineries, marketing
terminals, bulk plants, and pipeline terminals that receive flammable
and combustible liquids.
    The revised edition is a major rewrite of the document that
includes the development of policies and procedures to incorporate
management of an overfill protection process (OPP) and risk assessment.
The most significant changes include new requirements for: (1) A
written management system for overfill prevention processes; (2)
overfill risk-assessment processes; (3) expanded requirements for the
testing of OPP systems and related procedures; and (4) the use of
safety-instrumented systems (instruments that collect data used to

keep the overfill prevention systems operating safely) on new automatic
overfill prevention systems. The 5th edition revises the scope of the
standard to include dedicated pipeline relief tanks on breakout tanks
to the extent practicable. These additional requirements will result in
safer operation of applicable tanks.

B. The American Society of Mechanical Engineers (ASME)

    ASME BPVC (Section VIII, Divisions 1 and 2) were previously
approved for incorporation by reference and appears in the regulatory
text unchanged.
1. ASME B31.8, Gas Transmission and Distribution Piping Systems
    PHMSA is proposing to incorporate by reference ASME B31.8-2018,
``Gas Transmission and Distribution Piping Systems,'' November 20,
2018, (ASME B31.8), into Sec. Sec.  192.112(b); 192.619(a); 195.5(a);
and 195.406(a). This standard covers safety requirements associated
with the design, fabrication, installation, inspection, testing, and
operation and maintenance of pipeline facilities used for the
transportation of natural gas and liquefied petroleum gases when they
are vaporized and used as gaseous fuels.
    More specifically, ASME B31.8 addresses the following requirements
associated with the design, fabrication, installation, inspection,
testing, and operation and maintenance of pipeline facilities that are
referenced through the regulations. The revisions related to these
requirements are also summarized below:
     Fracture control for steel pipe using alternative maximum
allowable operating pressure in gas pipelines (Sec.  192.112(b)).
    [cir] The 2016 version made editorial changes such as numbering the
paragraphs associated with fracture control and arrest in 841.1. Some
relatively minor technical changes were made, such as adding a
clarification note regarding application of equations associated with
ductile facture.
    [cir] The 2018 version revises the equations for Charpy energy
values (aka Charpy V-notch absorbed energy or Charpy V-notch toughness
(CVN)) to use diameter instead of radius as a variable. This version
also includes a note that addresses situations in which the CVN exceeds
a certain value and full-sized test pieces are used. The note expands
already-existing requirements related to API 5L testing.
     Test pressure for determining maximum allowable operating
pressure in steel or plastic gas pipelines (Sec.  192.619(a)), testing
the pipeline for conversion to service for hazardous liquid pipelines
(Sec.  195.5(a)), and test pressure for determining maximum operating
pressure for liquid pipelines (Sec.  195.406(a)), which all reference
ASME B31.8 Appendix N-5.
    [cir] The revised version includes some editorial changes in
Appendix N-5 associated with renumbering of other referenced sections.
There are no technical changes in Appendix N-5.

Distribution Piping Systems,'' November 30, 2007, (ASME/ANSI B31.8).]
2. ASME B31.8S, Supplement to B31.8 on Managing System Integrity of Gas
Pipelines
    PHMSA is proposing to incorporate by reference ASME B31.8S-2016,
``Managing System Integrity of Gas Pipelines, Supplement to ASME
B31.8,'' October 31, 2016, (ASME/ANSI B31.8S) into Sec. Sec.  192.903
note to the definition of Potential impact radius; 192.907 introductory
text, (b); 192.911 introductory text, (i), (k), (l), (m); 192.913(a),
(b), (c); 192.917 (a), (b), (c), (d), (e); 192.921(a); 192.923(b);
192.925(b); 192.927(b), (c); 192.929(b); 192.933(c), (d); 192.935 (a),
(b); 192.937(c); 192.939(a); and 192.945(a). ASME B31.8S describes the
foundations for an effective integrity management (IM) program for gas
transmission pipelines. Along with subpart O of part 192, ASME B31.8S
provides the essential features of an integrity management program.
Section 3.2 of B31.8S addresses the potential impact factor for gases
other than standard quality natural gas that may be transported through
a gas transmission pipeline. Other sections are as follows: Section 4--
Gathering, Reviewing and Integrating Data; Section 5--Risk Assessment
and Reassessment Intervals; Section 6.2--Selection of In-line
Inspection Tools (ILI); Section 6.4--Direct Assessment Requirements for
External Corrosion and Internal Corrosion; Section 7--Remediation
Schedule and Immediate Repair Requirements; Section 9--Performance Plan
and Program Effectiveness; Section 10--Communications Plan; Section
11--Management of Change Process; Section 12--Quality Assurance
Process; Appendix A--Data Requirements of Each Threat; Appendix A3--
Direct Assessment requirements for the Stress Corrosion Cracking (SCC)
Threat; Appendix 4.3 and 4.4--Criteria and Risk Assessment and
Integrity Assessment for the Manufacturing Threat; and Appendix A7--
Criteria and Risk Assessment and Integrity Assessment, Response and
Mitigation and Performance Measures for the Third Party Damage Threat.
    The standard applies to onshore pipeline systems constructed with
ferrous materials (such as iron and steel) that transport gas. It is
frequently referenced throughout subpart O and is designed to provide
the operator with the information necessary to develop and implement an
effective integrity management program utilizing proven industry
practices and processes.
    Revisions to ASME B31.8S relative to the 2004 edition that is
currently incorporated by reference include added information on Stress
Corrosion Cracking Direct Assessments (SCCDA), an assessment method for
identifying stress corrosion cracking. The 2016 edition also provides
additional guidance on managing cracking threats. Other changes since
the 2004 edition include adding performance metrics for block valve
failures in Table 9.4, requiring examinations for immediate and 1-year
repair conditions discovered by direct assessment, and updates and
additions for references to secondary standards. In addition to the
above, each revision since 2004 includes other minor technical changes,
editorial revisions, and added or revised guidance. Together, PHMSA
expects these additions, updates, and clarifications to improve the
effectiveness of the Federal gas transmission integrity management
requirements.
    PHMSA is not proposing the incorporation by reference of the 2018
edition of ASME B31.8S, ``Managing System Integrity of Gas Pipelines,
Supplement to ASME B31.8,'' November 28, 2018, (ASME/ANSI B31.8S), into
Sec. Sec.  192.7(c)(6). The 2018 edition includes several minor
editorial changes that PHMSA found to be acceptable; however, the
changes in section 10 remove nearly all communications plan
requirements included in Sec.  192.911(m). PHMSA has not, therefore,
proposed incorporation of the 2018 edition. The 2016 version, in
contrast, retains the communication plan requirement in section 10 of
ASME B31.8S-2016. PHMSA requests comments regarding whether it should
incorporate by reference ASME B31.8S-2018.

3. ASME B36.10M, Welded and Seamless Wrought Steel Pipe
    PHMSA is proposing to incorporate by reference ASME B36.10M-2018,
``Welded and Seamless Wrought Steel Pipe,'' 2018 edition, October 12,
2018, into Sec.  192.279. This standard is proposed to replace the
current reference in Sec.  192.279 to Table C1 of ASME/ANSI B16.5. The
2003 and subsequent editions of ASME B16.5 remove Table C1; \6\ that
information is now in ASME B36.10M-2018. Therefore, PHMSA is proposing
to revise Sec.  192.279 to replace the phrase ``listed in Table C1 of
ASME/ANSI B16.5'' to ``listed in ASME B36.10M.''

C. ASTM International (Formerly American Society for Testing and
Materials)

    ASTM A672/A672M-09 was previously approved for incorporation by
reference and appears in the regulatory text unchanged.
1. ASTM A53/A53M, Standard Specification for Pipe, Steel, Black and
Hot-Dipped, Zinc-Coated, Welded and Seamless
    PHMSA is proposing to incorporate by reference ASTM A53/A53M-20,
``Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-
Coated, Welded and Seamless,'' July 1, 2020, into Sec.  192.113; Item
II, Appendix B to part 192; and Sec.  195.106(e). ASTM A53/A53M
specifies the design for seamless and welded black and hot-dipped
galvanized steel pipe in nominal pipe size (NPS) \1/8\ to NPS 26. The
standard also specifies requirements for tests of material properties,
hydrostatic tests, and non-destructive tests. The revised standards
published since the 2010 edition currently incorporated by reference
only incorporate minor editorial revisions or clarifications that are
expected to provide an equal or increased level of safety. The 2012
edition clarifies the chemical requirements table to allow additional
manganese content if carbon content is reduced (both carbon and
manganese increase the hardness and strength of steel but may lead to
welding issues with excessive content), the 2018 edition removes
language prescribing the method for measuring wall thickness and
allowing other engineering-acceptable methods, and the 2020 edition
states that galvanized pipe must be completely and evenly covered with
zinc. These revisions add some flexibility to the specifications.

Temperature Service,'' November 1, 2019, into Sec. Sec.  192.113; Item
1, Appendix B to part 192; and 195.106(e). This specification covers
seamless carbon steel pipe for high-temperature service in NPS \1/8\ to
NPS 48. The updates added since the 2010 edition currently incorporated
by reference include clarifying the supplementary requirements in the
ordering information, as well as the definition of single or double
random lengths of pipe with single random joints allowed from 17 to 24
foot lengths and double random joints being between 36 and 44 feet. The
updates also allow heat treatment of hot-finished pipe, require that
any tests be performed after heat treatment to ensure the tests are on
the finished product, add a note to the chemical requirements table to
allow additional maximum manganese content if maximum carbon content is
reduced (both carbon and manganese increase the hardness and strength
of steel but may lead to welding issues with excessive content), and
include other minor editorial changes. These revisions provide
additional flexibility and clarity to the specification.

3. ASTM A333/A333M, Standard Specification for Seamless and Welded
Steel Pipe for Low-Temperature Service and Other Applications With

Toughness,'' November 1, 2018, into Sec. Sec.  192.113; Item 1,
Appendix B to part 192; and 195.106(e). This specification covers
nominal (average) wall seamless and welded carbon and alloy steel pipe
intended for use at low temperatures and covers chemical, tensile
strength, mechanical testing, and other requirements. The standards
published since the 2011 edition that is currently incorporated by
reference only add minor editorial revisions. These include expanding
the scope of the standard to other applications with required notch
toughness (notch toughness indicates the ability of the steel to absorb
an impact without failing when a defect such as a notch, groove, or
gouge is present); changing the name of the element Columbium to the
more common, internationally used ``Niobium;'' changing ``minimum
impact test temperature'' to ``impact test temperature,'' which will
help standardize test temperature; clarifying procedures for impact
testing, which will help standardize testing; and incorporating changes
to the notes for the chemical requirements table. Adopting these
updates improves the clarity of the requirements, provides a greater or
equivalent level of safety, and ensures compatibility with other
standards.

4. ASTM A381, Standard Specification for Metal-Arc-Welded Carbon or
High-Strength Low-Alloy Steel Pipe for Use With High-Pressure
Transmission Systems
    PHMSA is proposing to incorporate by reference ASTM A381/A381M-18,
``Standard Specification for Metal-Arc-Welded Carbon or High-Strength
Low-Alloy Steel Pipe for Use With High-Pressure Transmission Systems,''
November 1, 2018, into Sec. Sec.  192.113; Item I, Appendix B to part
192; and 195.106(e). This specification covers straight-seam, double-
submerged arc-welded steel pipe (commonly referred to as DSAW pipe as
opposed to spiral-welded or electric-resistance-welded pipe) that is
intended for the fabrication of fittings and accessories for compressor
or pump-station piping and is suitable for high-pressure service at
outside diameters of 16 inches or greater. The revised standard
incorporates a number of changes, including: Clarifying quench and
temper requirements (when requested by a purchaser); updating tensile
and guided-bend testing requirements to include the use of ASTM A370
instead of the outdated requirements in the previous edition of the
standard; adding two new grades of material, Y70 and Y80, which have
similar requirements to API 5L X70 and API 5L X80 but are

higher-strength grades that have become more common in the pipeline
industry; and numerous editorial changes that update the document to
match the current ASTM style guidelines. The added quench and temper
requirements in this standard are part of a clause that only takes
effect if an operator agrees to enact it. This clause addresses
reheating pipe after it is manufactured to ensure that the atoms form
in an appropriate formation, and allows for this reheated pipe to be
water-quenched or tempered--in addition to the previously approved air-
cooling method--if the purchaser requests these cooling methods. In
addition, the standard contains references to other ASTM standards that
have changed since 1996, and the revised version incorporates these
changes. The referenced standards address various test methods and
general material and marking requirements for steel pipe in ASTM
specifications. These changes update and modernize the document, and
the improved testing requirements should provide a greater level of
safety.

specifies the design, fabrication, and testing requirements for
electric-fusion-welded (as opposed to arc-welded) steel pipe with added
filler metal. Specifically, the specification applies to pipe
fabricated from pressure vessel quality steel plate suitable for use at
high pressures at atmospheric and lower temperatures. The updated
standard includes minor changes from the 2010 edition--which is
currently incorporated by reference--that update and correct the tables
for plate specifications and heat-treatment parameters to account for
the introduction, revision, or obsolescence of pipe grades and related
heat-treatment practices. These revisions allow operators and
manufacturers to take advantage of advances in materials and
manufacturing technology, as well as to eliminate pipe grades and heat
treatments that are no longer used. In addition, the revised standard
clarifies tensile-test requirements to help ensure consistent testing
methodology. This change represents a minor advancement of the standard
and provides an equivalent or greater level of safety.

1. ANSI/MSS SP-44, Steel Pipeline Flanges
    PHMSA is proposing to incorporate by reference ANSI/MSS SP-44-2019,
``Steel Pipeline Flanges,'' April 2020 into Sec.  192.147(a). This
American National Standard Institute (ANSI)/Manufacturers
Standardization Society (MSS) Standard Practice (SP) covers pressure-
temperature ratings, materials, dimensions, tolerances, marking, and
testing of steel pipeline flanges. The revised edition specifies
material chemistry and strength requirements; clarifies definitions;
defines flange dimensions for weld-end, flange bolting, and flange-face
tolerances for flange raised-face height and bolt-hole diameter
marking; clarifies allowable heat-treatment methods; and makes impact
testing at -50 degrees F mandatory for grades over F42 for steel
pipeline flanges. The revised edition adds a new section on
manufacturing and inspection that requires a documented manufacturing
procedure and prescribes minimum testing requirements for the forging
method, heat treatment, machining and dimensions, mechanical tests,
non-destructive examination, and material traceability. Other changes
since the 2010 edition, which is currently incorporated by reference,
include more specific material chemistry and carbon-equivalent
standards for weldability, quality control to maintain strength and
dimensional requirements, heat-treatment requirements, and the addition
of a hardness-testing requirement. The revised edition also revises
requirements for markings and tolerances and includes updates regarding
ANSI approval, strength, and inspection-quality assurance. These new or
enhanced requirements improve manufacturing quality control and enhance
safety through more consistent flange tensile strength, chemistry, and
end tolerances for weldability and fit-up with other flanges. This SP
is ANSI-approved as a revised American National Standard and was
published in April 2020. PHMSA expects the quality improvement
requirements in this edition will help ensure more consistent flange
properties and dimensions, which should have operational and safety
benefits to operators during construction, pressure testing, and
operations.

pressure gas and oil transmission and distribution systems, including
pipelines, compressor stations, metering and regulating stations, and
mains.
    The revised edition includes revisions to product chemistry,
strength,

inspection quality assurance, chemical composition and carbon-
equivalent standards, heat-treatment practices, welding procedures for
the fittings, and recordkeeping requirements. The product chemistry
changes in the standard help ensure that carbon-equivalent computations
for modern types of steel are based upon the usage of a lower amount of
carbon in the fitting. The standard states that a fitting cannot exceed
0.45 percent of the carbon equivalent, and that operators must identify
any fitting in which the carbon equivalent exceeds 0.42 percent. This
change will help operators identify whether preheating is necessary
prior to welding a fitting to pipe.
    The updated standard also edits the heat-treatment standards to
require that the heat-treatment furnace must maintain a temperature
that is between -25 and 25 degrees Fahrenheit of the required furnace
temperature. The edited heat-treatment standards require annual
verification, specify the appropriate test standard that operators
should use, and compel the manufacturer to maintain test records.
Further, the revised standard outlines the heat-treatment processes
that operators can use to obtain stress-relieving, normalizing, or
quenching and tempering specified material properties. The standard
also requires manufacturers to maintain procedures and heat-treatment
records.
    The revised standard requires operators to review the heat-
treatment records for each test lot of heat-treated fittings for
consistency with both the fitting specifications and the prior fitting
heat-treatment results, as applicable. The standard notes that each
fitting must be manufactured in accordance with a manufacturing
procedure specification that specifies the fittings' starting material;
forming method; welding-procedure specification; heat-treatment
procedure with thermal cycles; machining requirements; inspection,
dimension, and test requirements; fitting end prep; coating; and
markings. The standard states that each manufacturer must have a
quality-control program that ensures their fittings conform to all
applicable requirements in the standard. Further, the standard requires
manufacturers to perform a minimum inspection test plan on each fitting
that outlines the type and number of tests that must be performed and
the specifications that the test must meet to ensure the quality of the
fitting.
    The MSS revised the updated edition of this standard with input
from PHMSA and other stakeholders. The revised edition includes
rewritten proof-test requirements and new requirements for segmentable
elbows, and adopts new requirements for manufacturers to have
manufacturing procedure specification and inspection test plans. More
stringent material requirements and improved manufacturing controls are
intended to address problems such as failures due to cracking or
insufficient material strength and welding issues caused by variations
in the chemistry or dimensions of flanges. PHMSA expects these
improvements will enhance safety. PHMSA expects the quality-improvement
requirements in this edition will help ensure more consistent fitting
properties and dimensions, which is expected to have operational and
safety benefits during construction, pressure testing, and operations.

E. NACE International (Formerly National Association of Corrosion
Engineers)

1. NACE SP0204, Standard Practice (SP): Stress Corrosion Cracking (SSC)
Direct Assessment Methodology
    PHMSA is proposing to incorporate by reference NACE SP0204-2015,
``Stress Corrosion Cracking (SCC) Direct Assessment Methodology,''
March 14, 2015, into Sec.  195.588(c). This SP provides a process and a
series of required steps for operators to use to assess the extent of
stress-corrosion cracking on a section of buried pipeline. The
methodology is designed as a screening tool to determine whether SCC is
a substantial risk on a pipeline system.
    The 2015 edition contains a few minor improvements from the 2008
edition. For example, the 2015 edition provides additional guidance
references regarding the susceptibility requirements for near-neutral
SCC and adds new references for recommended practices for near-neutral
SCC. Near-neutral-pH SCC is a transgranular form of SCC that occurs on
underground pipelines and is associated with a near-neutral-pH
electrolyte. This form of cracking typically experiences limited
branching and is associated with some crack wall corrosion, as well as
occasional pipe surface corrosion. It is also referred to as low-pH or
non-classical SCC. The SP also defines parameters quantifying SCC
severity based on the size and depth of SCC found in the field and
notes that fatigue and corrosion fatigue must be considered on liquid
pipelines. Some of these revisions have already been integrated in
recent industry projects. PHMSA expects these changes will improve the
reliability of operators' SCC direct assessment plans and thereby
increase efficiency, help remove variables and guesswork, and allow
operators to better target potential SCC sites. The additional
definitions and guidance also promote more consistent SCC evaluations,
as consideration of additional variables will allow operators to
further refine or classify suspected SCC and more consistently
integrate these classifications into assessment or remediation plans.

F. National Fire Protection Association (NFPA)

    NFPA-30 (2012) was previously approved for incorporation by
reference and appears in the regulatory text unchanged.
1. NFPA 58, Liquefied Petroleum Gas Code
    PHMSA is proposing to incorporate by reference NFPA 58, ``Liquefied
Petroleum Gas Code,'' 2020 edition, October 25, 2019, into Sec. Sec.
192.7 and 192.11(a), (b), and (c). NFPA 58 specifies requirements for
the ``storage, handling, transportation, and use of liquefied petroleum
gas.'' The PSRs require any plant that supplies liquefied petroleum to
a pipeline system and any pipeline system that transports only
petroleum gas or petroleum gas mixtures to meet the requirements of
NFPA 58 in addition to the requirements of part 192. PHMSA did not
incorporate prior editions of this standard due to content and
requirements that could potentially have conflicted with elements of 49
CFR part 192. The revised edition, however, alleviates or removes the
potential conflicts.
    The revised edition of NFPA 58 includes more detailed,
comprehensive sections covering the design and installation of
liquefied petroleum systems. Significant additions include new or
revised standards for regulators regarding modified piping, vapor
systems, leak detection, containers, and structural supports.
Furthermore, the revised edition references more recent editions of
almost all the standards referenced in the 2004 edition that is
currently incorporated by reference. The new references included in the
revised edition are ANSI B1.20.1, ANSI/CSA 6.26(LC1), ANSI Z21.18/CSA
6.3, ANSI Z21.80/CSA 6.22, API 607, ASTM E119, ASTM F1055, ASTM F2945,
CAN/ULC

S642, CGA-6.3, CGA-S-1.1, CGA-S-1.3, CSA 6.32(LC4a), CSA B149.5, ISO/NP
19825, NFPA 13, NFPA 55, NFPA 99, UL 21, UL 125, UL 263, UL 514B, UL
569, UL 1337, UL 1660, UL 1769, and UL 2227. The revised edition
removes references to ASTM B539, NFPA 50B, and NFPA 251. In addition to
the safety improvements, the revised edition reduces the potential for
conflict with the code when new systems are designed, built, and
maintained in accordance with the more recent version of the standards
referenced in NFPA 58.
    The 2020 edition of this standard incorporates a number of changes
that maintain or enhance the level of safety established in the
previous editions of the standard. These changes include allowing
operators to use additional types of steel pipe, including schedule 10
steel (solely for aboveground vapor service) or austenitic stainless
steel pipes. The revised standard allows for the use of schedule 10
steel in limited applications, which aids the pipeline industry by
allowing them to use schedule 10 pipe that they might already plan to
purchase for another application for aboveground vapor service as well.
This change benefits industry while maintaining an equivalent level of
safety. The revised standard also allows for the use of austenitic
stainless steel, which is a type of stainless steel that has a specific
austenitic crystal structure (a face-centered cubic structure) that
results in higher heat and corrosion resistance. This steel is commonly
used in extreme temperature applications, and can be found as a
component in duplex stainless steels. Pipe manufacturers often provide
mixed steel types in piping batches, and the exclusion of this steel in
previous versions of this standard was based on the potential for
variation. However, the characteristics of the steel have since been
reviewed and determined to be within tolerance for general LP
applications.
    Further, the standard revises both fire extinguisher requirements
and the scope of chapter 15. The chapter 15 revisions enhance safety by
deleting superfluous installation requirements, incorporating
operations and maintenance requirements, and removing duplicative
language applicable to U.S. DOT-regulated systems. The fire
extinguisher revisions confirm that operators must be able to quickly
shut off access to a fuel source if they intend to use fire
extinguishers in the event of a liquefied petroleum gas fire. This
change streamlines NFPA 58 and other relevant industry standards.
    Finally, the 2020 edition of the standard includes requirements
regarding face-seal inspections, fire-resistance-rated materials, and
noncombustible materials. Regarding the face-seal inspections, the
updated standard requires that operators must inspect face seals for
CGA 791 and 793 connections before filling a cylinder. Additionally,
the standard notes that operators must refrain from filling cylinders
and replace the relevant valve if they find that the face seal is
defective. The standard also notes that operators must ensure that
noncombustible and specific fire-resistance-rated materials fulfill
specific requirements.
    [Replaces IBR: NFPA-58, ``Liquefied Petroleum Gas Code (LP-Gas
Code),'' 2004 edition, April 1, 2004, (NFPA-58).]
2. NFPA 59, Utility LP-Gas Plant Code
    PHMSA is proposing to incorporate by reference NFPA 59, ``Utility
LP-Gas Plant Code,'' 2018 edition, August 17, 2017, into Sec.
192.11(a), (b), and (c). In the PSRs, the requirements for liquefied
petroleum gas facilities are mostly defined in NFPA 59 and NFPA 58, as
applicable. NFPA 59 specifies the design, construction, location,
installation, operation, and maintenance of utility gas plants.
Compared to NFPA 58, NFPA 59 generally covers larger facilities.
    Four editions of NFPA 59 have been issued since 2004 (2008, 2012,
2015, and 2018). The revisions made from the 2008 edition to the 2015
edition include provisions on corrosion protection; personnel training
relative to the operation or maintenance of propane-air mixing
equipment; and provisions for sizing pressure-relief devices for
propane installations over 300 psig. These provisions are included in
the 2018 edition. Further, the 2018 edition of NFPA 59 includes more
detailed, comprehensive sections covering the design and maintenance of
liquefied petroleum plants. Significant changes include adding and
clarifying definitions, removing out-of-scope topics conflicting with
part 192, such as vehicle fuel systems, and expanding the scope of
protected components previously not covered, such as the protection of
in-plant piping. Adopting the 2018 edition reduces the potential for
conflict with the code when new systems are designed, built, or
maintained to the specifications of the more recent version of such
referenced standards in NFPA 59.
    [Replaces IBR: NFPA-59, ``Utility LP-Gas Plant Code,'' 2004 edition
(NFPA-59).]
3. NFPA 70, National Electrical Code (NEC)
    PHMSA proposes to incorporate by reference NFPA 70, ``National
Electrical Code (NEC),'' 2017 edition, August 23, 2016, into Sec. Sec.
192.163(e) and 192.189(c). NFPA 70, also known as the National
Electrical Code (NEC), covers the installation and removal of
electrical equipment, conductors, and conduits in structures and
outdoor areas. The NEC is a foundational standard for electrical safety
in residential, commercial, and industrial implementations. It is
referenced in the PSRs to provide requirements for the safe
installation of electrical equipment at compressor stations in natural
gas pipeline facilities.
    The 2017 edition includes several revisions from the 2011 edition
that is currently incorporated by reference. Changes include new
provisions for energy-storage systems, labeling requirements for
equipment consistent with NFPA 70E, and clearance requirements for
certain electrical equipment. The 2017 edition also expands marking and
maintenance requirements for emergency electrical systems and requires
a minimum temperature rating for fire alarm cables. The improvements in
the 2017 edition of NFPA 70 enhance the safety of electrical systems
and equipment in compressor stations, mitigating potential ignition
risks.
    [Replaces IBR: NFPA-70, ``National Electrical Code,'' 2011 edition,
September 24, 2010, (NFPA-70).]

III. Miscellaneous Amendments

    PHMSA is also proposing editorial amendments and corrections to the
PSRs. The most significant of these revisions responds to a petition
for rulemaking from the American Gas Association (AGA). In addition to
petitioning PHMSA to incorporate the most recent edition of NFPA 59 by
reference, AGA suggested edits to Sec.  192.11 to clarify the scope of
NFPA 58 and NFPA 59. The regulations currently require operators of
liquefied petroleum plants and pipelines to meet the requirements of
both NFPA 58 and NFPA 59. The proposed change clarifies that operators
must only meet the requirements for the NFPA standard that is
applicable to the type of facility they operate, based on the scope and
applicability statements in those standards. Generally, NFPA 58 applies
to liquefied petroleum pipeline systems and NFPA 59 to utility-scale
liquefied petroleum gas plants.
    Another revision corrects the minimum wall thickness tables for
plastic pipe made of polyethylene (PE),

polyamide (PA) 11, and polyamide 12 in Sec.  192.121 to include
specifications for pipe with a copper tubing size (CTS) of 1\1/4\
inches and correct the minimum wall thickness for 1 inch CTS pipe. The
minimum wall thickness and, more specifically, the dimension ratio (DR;
the ratio of outside diameter to wall thickness) being proposed for
these sizes is consistent with values already specified for adjacent
sizes. Plastic pipe, especially PE, is very common on gas distribution
systems. On November 20, 2018, PHMSA published a final rule (83 FR
58694) that allowed plastic pipe to operate with a design factor (a
derating factor) of 0.4 rather than 0.32 provided it met various
requirements, including having a minimum wall thickness as defined in
the tables in Sec.  192.121. As described in the final rule, the
Regulatory Impact Analysis, and AGA's petition for rulemaking, the
revised design factor allows the use of approximately 17 percent less
material or 11 percent higher capacity for a given outside
specification.
    The NPRM included listings for CTS sizes of \1/2\ and \3/4\ inch
for PE pipe. In response to comments, PHMSA included CTS sizes for PA11
and PA12 pipe and IPS sizes below 1 inch for all materials. However,
stakeholders have subsequently requested PHMSA consider including 1\1/
4\ inch CTS as well. This amendment would allow the use of 1\1/4\ inch
CTS pipe with a 0.4 design factor provided the pipe wall is at least
0.121 inches thick. A wall thickness of 0.121 corresponds to a
dimension ratio of approximately 11. This is the same SDR as what is
currently permitted for 1\1/4\ inch Iron Pipe Size (IPS) and 1 inch CTS
and 1 inch IPS. This change would reduce the cost to produce this size
of plastic pipe by approximately 10 percent. The revised design factor
is already permitted for similar, adjacent sizes such as 1\1/4\ inch
IPS pipe. It was not PHMSA's intent to exclude specifications such as
1\1/4\ inch CTS. The costs and benefits of this proposal were accounted
for in the RIA for the 2018 final rule.
    Other proposed editorial revisions that PHMSA proposes are:
     Update references to PHMSA's website at https://portal.phmsa.dot.gov/ in Sec. Sec.  191.22 (b) and (c), and 195.64;
     Copy the definition for ``master meter system'' used in
part 191 to part 192. The term ``master meter system'' is referenced in
both part 191 and part 192, however it is only defined in part 191 at
Sec.  191.3. The definition would be added to part 192 at Sec.  192.3;
     Correct a reference to flange requirements in Sec.
192.147(a) to clarify that flanges must meet ASME B16.5 or ANSI/MSS SP-
44, not both;
     Correct the placement of the word ``in'' in Sec.
192.153(d);
     Remove reference to an inactive phone number for the NPMS
program in Sec. Sec.  192.727(g) and 195.59(a);
     Remove references to Sec.  195.242(c) and (d) in Sec.
195.1(c) because this section no longer exists in the regulations;
     Correct Sec.  195.3(c)(3) to reflect that ASME B31.4 is no
longer referenced in Sec.  195.452(h); and
     Add the house number to the address for DOT headquarters
in Sec.  192.805.

IV. Regulatory Analyses and Notices

A. Summary/Legal Authority for This Rulemaking

    This NPRM is published under the authority of the Federal Pipeline
Safety Laws (49 U.S.C. 60101 et seq.). Section 60102 authorizes the
Secretary of Transportation to issue regulations governing the design,
installation, inspection, emergency plans and procedures, testing,
construction, extension, operation, replacement, and maintenance of
pipeline facilities. Further, section 60102(l) states that the
Secretary shall, to the extent appropriate and practicable, update
incorporated industry standards that have been adopted as a part of the
PSRs. This NPRM proposes to incorporate by reference 25 updated
editions of standards currently incorporated by reference and one new
standard. In addition, this NPRM proposes to make several other minor
clarifying and editorial changes to the PSRs.

Executive Order 12866 and DOT Policies and Procedures for Rulemaking

    Executive Order 12866 (``Regulatory Planning and Review'') (58 FR
51735; Oct. 4, 1993) requires agencies to regulate in the ``most cost-
effective manner,'' to make a ``reasoned determination that the
benefits of the intended regulation justify its costs,'' and to develop
regulations that ``impose the least burden on society.'' This NPRM is
not considered a significant regulatory action under Executive Order
12866. Accordingly, this NPRM was not reviewed by OMB. DOT also
considers this NPRM to be non-significant under its Policies and
Procedures for Rulemakings (49 CFR part 5).
    In this NPRM, PHMSA is proposing to incorporate by reference
updated editions of 25 standards currently referenced in parts 192 and
195 and one new standard. According to the annual reports pipeline that
operators submit to PHMSA, there are more than 3,244 entities operating
hazardous liquid, natural gas transmission, gathering, distribution
systems, and liquefied natural gas facilities as of September 12, 2018.
The amendments in this NPRM should enhance safety and reduce the
compliance burden on the regulated industry. However, the anticipated
cost savings and benefits have not been quantified. PHMSA expects the
cost savings and benefits of incorporating these standards to be
negligible. The industry standards developed and adopted by consensus
are largely accepted by the pipeline industry.
    In addition to updating consensus standards, PHMSA is proposing
miscellaneous non-substantive amendments and clarifications of
regulatory language in certain provisions. Since these editorial
changes are relatively minor, the proposed changes would not require
pipeline operators to undertake new pipeline safety initiatives and are
expected to have negligible cost implications. To the extent that the
changes have an impact, they are expected to increase the clarity of
the PSRs and help improve the safety of the Nation's pipeline systems.
    In accordance with the NTTAA and OMB Circular A-119, PHMSA reviews
new editions and revisions to relevant standards and publishes a NPRM
approximately every two years to incorporate by reference new or
updated consensus standards. This practice is consistent with the
intent of the NTTAA and OMB directives to avoid the need for developing
government-written standards that could potentially result in
regulatory conflicts with updated industry standards and an increased
compliance burden on industry.

Executive Order 13771

    This proposed rule is not expected to be an Executive Order 13771
regulatory action because this proposed rule is not significant under
Executive Order 12866. Details on the estimated cost savings of this
proposed rule can be found in the Executive Order 12866 section above.

Executive Order 13132

    PHMSA analyzed this NPRM in accordance with the principles and
criteria contained in Executive Order 13132, ``Federalism,'' (64 FR
43255; Aug. 10, 1999). Executive Order 13132 requires agencies to
assure meaningful and timely input by State and local officials in the
development of regulatory policies that may have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the

distribution of power and responsibilities among the various levels of
government.'' While the proposed rule may operate to preempt some State
requirements, it does not impose any regulation that has substantial
direct effects on the States, the relationship between the national
government and the States, or the distribution of power and
responsibilities among the various levels of government. The pipeline
safety laws, specifically 49 U.S.C. 60104(c), prohibit State safety
regulation of interstate pipeline facilities. However, under the
pipeline safety laws, States can augment pipeline safety requirements
for intrastate pipeline facilities, but may not approve safety
requirements less stringent than those required by Federal law. A State
may also regulate an intrastate pipeline facility PHMSA does not
regulate. Therefore, the consultation and funding requirements of
Executive Order 13132 do not apply.

Executive Order 13175

    PHMSA has analyzed this NPRM according to the principles and
criteria in Executive Order 13175, ``Consultation and Coordination with
Indian Tribal Governments,'' (65 FR 67249; Jan. 29, 2014). Because this
NPRM does not significantly or uniquely affect the communities of the
Indian tribal governments or impose substantial direct compliance
costs, the funding and consultation requirements of Executive Order
13175 do not apply. We invite Indian tribal governments to provide
comments on the costs and effects that this or a future rulemaking
could potentially have on tribal communities.

Regulatory Flexibility Act, Executive Order 13272 and DOT Procedures
and Policies

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.), requires an
agency to review regulations to assess their impact on small entities,
unless the agency determines the rule is not expected to have a
significant impact on a substantial number of small entities. PHMSA
estimates the costs of incorporating these standards to be negligible
as industry standards developed and adopted by consensus are largely
accepted and followed by the pipeline industry, which assures that the
industry is not forced to comply with several different standards to
accomplish the same safety goal. Most pipeline operators already
purchase and apply industry standards as part of common business
practice.
    Based on the information available about the anticipated impact of
this NPRM, PHMSA does not anticipate that this NPRM will have a
significant economic impact on a substantial number of small entities,
under Section 605 of the Regulatory Flexibility Act (5 U.S.C. 605),
because the costs of the NPRM are expected to be negligible.
    This NPRM was also developed in accordance with Executive Order
13272, ``Proper Consideration of Small Entities in Agency Rulemaking,''
(68 FR 7990; Feb. 19, 2003), and DOT's procedures and policies to
promote compliance with the Regulatory Flexibility Act to ensure that
potential impacts on small entities of a regulatory action are properly
considered.

Paperwork Reduction Act

    PHMSA has analyzed this NPRM in accordance with the Paperwork
Reduction Act of 1995 (PRA) (Pub. L. 104-13; May 22, 1995). The PRA
requires Federal agencies to minimize paperwork burden imposed on the
American public by ensuring maximum utility and quality of Federal
information, ensuring the use of information technology to improve the
Federal Government's performance and accountability for managing
information collection activities. This NPRM does not impose any new
information collection requirements or modify any existing information
collections requirements.

Regulation Identifier Number

    A regulation identifier number (RIN) is assigned to each regulatory
action listed in the Unified Agenda of Federal Regulations. The
Regulatory Information Service Center publishes the Unified Agenda in
April and October of each year. The RIN number contained in the heading
of this document can be used to cross-reference this action with the
Unified Agenda.

Unfunded Mandates Reform Act of 1995

    This NPRM will not impose unfunded mandates under the Unfunded
Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4; March 22, 1995). The
statutory thresholds established in UMRA were $50 million for
intergovernmental mandates and $100 million for private-sector mandates
in 1996. According to the Congressional Budget Office, the thresholds
for 2019, which are adjusted annually for inflation, are $82 million
and $164 million, respectively, for intergovernmental and private-
sector mandates.\7\ The NPRM is not expected to exceed these thresholds
in any one year to either State, local or tribal governments, in the
aggregate, or to the private sector, and would be the least burdensome
alternative that achieves the objective of this NPRM. Therefore, PHMSA
is not required to prepare a written statement.

Environmental Assessment

    The National Environmental Policy Act of 1969, 42 U.S.C. 4321-4375,
requires Federal agencies to analyze proposed actions to determine
whether the action will have a significant impact on the human
environment. The Council on Environmental Quality regulations require
Federal agencies to conduct an environmental review considering: (1)
The need for the proposed action; (2) alternatives to the proposed
action; (3) probable environmental impacts of the proposed action and
alternatives; and (4) the agencies and persons consulted during the
consideration process (40 CFR 1508.9(b)). In this NPRM, PHMSA proposes
to incorporate 25 updated editions of currently referenced standards
and one new standard.
    Description of Action: The NTTAA directs Federal agencies to use
voluntary consensus standards and design specifications developed by
voluntary consensus standard bodies instead of government-developed
voluntary technical standards, when applicable. There are currently
more than 80 standards incorporated by reference in parts 192, 193, and
195 of the PSRs.
    PHMSA engineers and subject matter experts participate on 25
standards development committees to keep current on committee actions.
PHMSA will only propose to adopt standards into the Federal regulations
that meet the agency's directive(s) to ensure the best interests of
public and environmental safety are served.
    Purpose and Need: Many of the industry standards currently
incorporated by reference in the PSRs have been revised and updated to
incorporate and promote new technologies and methodologies. This

NPRM will allow operators to use new technologies by incorporating new
editions of the standards into the PSRs.
    PHMSA's technical and subject matter experts continually review the
actions of pipeline standards developing committees and study industry
safety practices to ensure that their endorsement of any new editions
or revised standards incorporated into the PSRs will improve public
safety, as well as provide protection for the environment. If PHMSA
does not amend the PSRs to keep up with industry practices, it could
potentially have an adverse effect on the safe transportation of energy
resources.
    These proposed amendments would make the regulatory provisions more
consistent with current technology and would therefore promote the safe
transportation of hazardous liquids, natural and other gases, and
liquefied natural gas by pipeline.
    Alternatives Considered: In developing this NPRM, PHMSA considered
two alternatives:
    Alternative (1): Take no action and continue to incorporate only
the existing standards currently referenced in the PSRs. Because
PHMSA's goal is to facilitate pipeline safety and incorporate
appropriate and up to date consensus standards, PHMSA rejected the no
action alternative. This alternative would potentially result in
forgoing the safety and environmental improvements in the updated
standards.
    Alternative (2): Adopt the above-described amendments and
incorporate updated editions of voluntary consensus standards to allow
pipeline operators to use current technologies. This is the proposed
alternative. PHMSA's goal is to incorporate by reference all or parts
of updated editions of voluntary consensus standards into the PSRs to
allow pipeline operators to use current technology, new materials, and
other industry and management practices. Another goal is to update and
clarify certain provisions in the regulations.
    Environmental Consequences: The Nation's pipelines are located
throughout the United States, both onshore and offshore, and traverse a
variety of environments--from highly populated urban sites to remote,
unpopulated rural areas. The Federal pipeline regulatory system is a
risk management system that is prevention-oriented and focused on
identifying safety hazards and reducing the probability and quantity of
a natural gas or hazardous liquid release. Pipeline operators are
required to develop and implement IM programs to enhance safety by
identifying and reducing pipeline integrity risks.
    Pipelines subject to this NPRM transport hazardous liquids and
natural gas, and therefore a spill or leak of the product could affect
the physical environment as well as the health and safety of the
public. The release of hazardous liquids or natural gas can cause the
loss of cultural and historical resources (e.g., properties listed on
the National Register of Historic Places), biological and ecological
resources (e.g., coastal zones, wetlands, plant and animal species and
their habitats, forests, grasslands, offshore marine ecosystems),
special ecological resources (e.g., threatened and endangered plant and
animal species and their habitats, national and State parklands,
biological reserves, wild and scenic rivers), and the contamination of
air, water resources (e.g., oceans, streams, lakes), and soil that
exist directly adjacent to and within the vicinity of pipelines.
Incidents involving pipelines can result in fires and explosions,
causing damage to the local environment. Depending on the size of a
spill or gas leak and the nature of the failure zone, the potential
impacts could vary from property damage or environmental damage to
injuries or, on rare occasions, fatalities.
    Compliance with the PSRs substantially reduces the possibility of
an accidental release of product. Updating new industry standards or
those already incorporated into the PSRs can provide operators with the
advantages and added safety that can accompany the application of newer
technologies. These standards are based on the accumulated knowledge
and experience of owners, operators, manufactures, risk management
experts and others involved in the pipeline industry as well as
government agencies who write the regulations to ensure the products
are moved safely throughout the country. PHMSA staff actively
participates in the standards development process to ensure each
standard incorporated will enhance safety and environmental protection.
Newer editions are not automatically incorporated but reviewed in
detail. PHMSA reviewed each of the standards described in this proposed
rule and have determined that most of the updates involve minor changes
such as editorial changes, inclusion of a best practices, or similar
changes.
    The majority of updates proposed for incorporation into this NPRM
increase safety standards with the direct intent to decrease risk. In a
small number of instances, standards organizations relax standards to
reduce industry burden where justified by low risk, overlapping
protections, or technological innovation. One provision that allows for
relaxation are the less conservative design sloshing wave height
calculations in the revised edition of API Std 650, allowing welders
qualified in a fixed position to be qualified also to weld in the roll
position in the 21st edition of API Std 1104, and eliminating the need
to calculate evaporation rates in the 7th edition of API Std 2000.
PHMSA has determined that the safety improvements in API Std 650, API
Std 1104, and API Std 2000 offset those changes.
    Conclusion--Degree of Environmental Impact: PHMSA incorporates
consensus standards that will allow the pipeline industry to use
improved technologies, new materials, performance-based approaches,
manufacturing processes, and other practices to enhance public health,
safety, and welfare. PHMSA's goal is to ensure hazardous liquids,
natural and other gases, and liquefied natural gas transported by
pipeline will arrive safely to their destinations.
    PHMSA invites comments on the potential impact on human health or
the environment that would result if this rule was issued.

Executive Order 13211

    Executive Order 13211 (``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use'') (66 FR
28355; May 22, 2001) requires Federal agencies to prepare a Statement
of Energy Effects for any ``significant energy action.'' Under the
Executive Order, a ``significant energy action'' is defined as any
action by an agency (normally published in the Federal Register) that
promulgates, or is expected to lead to the promulgation of, a final
rule or regulation (including a notice of inquiry, ANPRM, and NPRM)
that (1)(i) is a significant regulatory action under Executive Order
12866 or any successor order and (ii) is likely to have a significant
adverse effect on the supply, distribution, or use of energy; or (2) is
designated by the Administrator of the Office of Information and
Regulatory Affairs as a significant energy action.
    Transporting gas and petroleum affects the Nation's available
energy supply. However, this NPRM would not be a significant energy
action under Executive Order 13211. It also would not be a significant
regulatory action under Executive Order 12866 and would not likely have
a significant adverse effect on the supply, distribution, or use of
energy. This NPRM has not been designated as a significant energy
action.

National Technology Transfer and Advancement Act

    As discussed above, the National Technology Transfer and
Advancement Act of 1995 (15 U.S.C. 272 note) directs Federal agencies
to use voluntary consensus standards in their regulatory activities
unless doing so would be inconsistent with applicable law or otherwise
impractical. Voluntary consensus standards are technical standards
(e.g., specification of materials, test methods, or performance
requirements) that are developed or adopted by voluntary consensus
standards bodies. This proposed rule updates 26 voluntary consensus
standards, which are discussed in detail in the ``Summary of Standards
Incorporated by Reference'' section.
