49 CFR Parts 191, 192, and 195

[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

[[Page 3940]]

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 <a href="/cdn-cgi/l/email-protection#ef9f87829c8e9c9b8e818b8e9d8b9caf8b809bc1888099"><span class="__cf_email__" data-cfemail="6111090c12001215000f050013051221050e154f060e17">[email protected]</span></a> 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

[[Page 3941]]

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

[[Page 3942]]

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.

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

[[Page 3944]]

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:
    <bullet> 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.
    <bullet> 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.

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 
Required Notch Toughness
    PHMSA is proposing to incorporate by reference ASTM A333/A333M-18, 
``Standard Specification for Seamless and Welded Steel Pipe for Low-
Temperature Service and Other Applications with Required Notch 
Toughness,'' November 1, 2018, into Sec. Sec.  192.113; Item 1,

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

[[Page 3946]]

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.

5. ASTM A671/671M, Standard Specification for Electric-Fusion-Welded 
Steel Pipe for Atmospheric and Lower Temperatures
    PHMSA is proposing to incorporate by reference ASTM A671/A671M-20, 
``Standard Specification for Electric-Fusion-Welded Steel Pipe for 
Atmospheric and Lower Temperatures,'' March 1, 2020, into Sec. Sec.  
192.113; Item 1, Appendix B to part 192; and 195.106(e). ASTM A671/671M 
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.

``Standard Specification for Carbon and Alloy Steel Pipe, Electric-
Fusion-Welded for High-Pressure Service at High Temperatures,'' 
November 1, 2019, into Sec. Sec.  192.113; Item 1, Appendix B to part 
192; and 195.106(e). This standard specifies the design, composition, 
fabrication, and testing of carbon and alloy steel pipe. The changes in 
the revised edition include a requirement that ASTM A387/A387M Grade 91 
material be designated and marked by Type 1 or Type 2 when required by 
that standard, as well as minor revisions to the ordering information 
specifications to differentiate between plate grades and pipe grades. 
In addition, the revised edition changes the name of the element with 
atomic number 41 from Columbium to Niobium. These minor revisions make 
the specification more consistent with other manufacturing standards 
and improve the clarity of the document.

D. Manufacturers Standardization Society (MSS) of the Valve and 
Fittings Industry

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.

2. MSS SP-75, High-Test, Wrought, Butt-Welding Fittings
    PHMSA proposes to incorporate by reference MSS SP-75-2019, ``High-
Test, Wrought, Butt-Welding Fittings,'' December 2019 into Sec.  
195.118(a). This MSS SP specifies requirements for factory-made, 
seamless, and electric-welded carbon and low-alloy steel butt-welding 
fittings. The SP states that it is applicable to fittings used in high-
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,

[[Page 3947]]

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

[[Page 3948]]

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

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.

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),

[[Page 3949]]

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:
    <bullet> Update references to PHMSA's website at https://portal.phmsa.dot.gov/ in Sec. Sec.  191.22 (b) and (c), and 195.64;
    <bullet> 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;
    <bullet> 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;
    <bullet> Correct the placement of the word ``in'' in Sec.  
192.153(d);
    <bullet> Remove reference to an inactive phone number for the NPMS 
program in Sec. Sec.  192.727(g) and 195.59(a);
    <bullet> Remove references to Sec.  195.242(c) and (d) in Sec.  
195.1(c) because this section no longer exists in the regulations;
    <bullet> Correct Sec.  195.3(c)(3) to reflect that ASME B31.4 is no 
longer referenced in Sec.  195.452(h); and
    <bullet> 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

[[Page 3950]]

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.

    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

[[Page 3951]]

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.
