Pipeline Safety: Breakout Tank Inspection Rule

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: Breakout tanks are used to ``relieve surges in a hazardous 
liquid pipeline system'' or to ``receive and store hazardous liquid 
transported by a pipeline for reinjection and continued transportation 
by pipeline.'' American Petroleum Institute Standard 653 (API Std 653) 
sets industry standards for the inspection, repair, alteration, and 
reconstruction of aboveground storage tanks. PHMSA currently 
incorporates the 3rd edition of API Std 653 (issued December 2001) by 
reference into its regulations for breakout tanks. In this rulemaking, 
PHMSA is proposing to update its regulations for breakout tanks to 
incorporate the 5th edition of API Std 653 (issued November 2014) by 
reference. As a key part of this, PHMSA is proposing to authorize the 
use of risk-based inspection (RBI) procedures for establishing the 
inspection intervals of in-service breakout tanks.

DATES: Comments on this NPRM must be submitted by August 3, 2026. A 
public meeting of PHMSA's statutory advisory committees will be held on 
a date to be announced in the Federal Register.

SUPPLEMENTARY INFORMATION:

I. Executive Summary

    API Std 653 sets standards for the inspection, repair, alteration, 
and reconstruction of aboveground storage tanks. PHMSA currently 
incorporates the 3rd edition of API Std 653, as issued in December 2001 
with addenda and errata through April 2008, by reference into its part 
195 regulations for breakout tanks. Breakout tanks are tanks that 
operators use to ``relieve surges in a hazardous liquid pipeline 
system'' or to ``receive and store hazardous liquid transported by a 
pipeline for reinjection and continued transportation by pipeline.'' 
(49 CFR 195.2).
    In this rulemaking, PHMSA is proposing to update its part 195 
regulations for breakout tanks to incorporate the 5th edition of API 
Std 653, as issued in November 2014 with addendums and errata through 
July 2025, by reference. PHMSA is also proposing to revise Sec.  
195.432 to authorize the use of RBI procedures for establishing the 
inspection intervals of in-service breakout tanks. PHMSA estimates that 
adopting this proposal will result in cost savings of between $24.5 to 
$125.7 million per year using a three percent discount rate or between 
$29.3 to $150.1 million per year using a seven percent discount rate.

II. Background

    PHMSA's Federal safety standards at part 195 apply to breakout 
tanks. Breakout tanks are used by pipeline operators to ``relieve 
surges in a hazardous liquid pipeline system'' or to ``receive and 
store hazardous liquid transported by a pipeline for reinjection and 
continued transportation by pipeline.'' (49 CFR 195.2). Breakout tanks 
are subject to certain specific requirements in part 195, including (1) 
Sec.  195.205, which prescribes requirements for the repair, 
alteration, and reconstruction of in-service breakout tanks; (2) Sec.  
195.307, which prescribes requirements for pressure testing aboveground 
breakout tanks; and (3) Sec.  195.432, which prescribes requirements 
for the inspection of in-service breakout tanks. While not relevant to 
the proposals at issue in this proceeding, the general requirements in 
part 195 for pipeline systems and pipeline facilities also apply to 
breakout tanks, subject to a conflict preemption provision.\1\
---------------------------------------------------------------------------

    \1\ 49 CFR 195.1(c) ``Breakout tanks that are subject to this 
part must comply with requirements that apply specifically to 
breakout tanks and, to the extent applicable, with requirements that 
apply to pipeline systems and pipeline facilities. If a conflict 
exists between a requirement that applies specifically to breakout 
tanks and a requirement that applies to pipeline systems or pipeline 
facilities, the requirement that applies specifically to breakout 
tanks prevails.''
---------------------------------------------------------------------------

    PHMSA's regulations for breakout tanks date to the 1969 final rule 
that prescribed the original version of the part 195 regulations.\2\ 
One of those regulations, codified at Sec.  195.432, established 
requirements for the inspection of storage vessels. It stated that 
``[e]ach carrier shall, at intervals not exceeding 12 months, inspect 
each

[[Page 32920]]

storage vessel (including atmospheric and pressure tanks).'' \3\

Maintenance, 34 FR 15473 (Oct. 4, 1969).
    \3\ 34 FR at 15482.
---------------------------------------------------------------------------

    In 1981, a PHMSA predecessor, the Research and Special Programs 
Administration (RSPA), issued a final rule recodifying the part 195 
regulations to reflect the enactment of the Hazardous Liquid Pipeline 
Safety Act of 1979 (Pub. L. 96-129).\4\ As part of the recodification, 
RSPA readopted the inspection requirements in Sec.  195.432 and added a 
definition for the term ``breakout tank.'' \5\ The following year, RSPA 
issued another final rule adjusting the inspection interval in Sec.  
195.432 to provide operators with additional scheduling flexibility. 
Rather than requiring a fixed 12-month interval, RSPA amended Sec.  
195.432 to permit the inspection of breakout tanks ``at intervals not 
exceeding 15 months, but at least once each calendar year.'' \6\
---------------------------------------------------------------------------

1981).

the development of PHMSA's breakout tank definition, see Exxon Corp.

    \6\ Transportation of Natural and Other Gas and Hazardous 
Liquids by Pipeline; Inspection and Test Intervals, 47 FR 46850, 
46852 (Oct. 21, 1982).
---------------------------------------------------------------------------

    Nearly two decades later, in 1999, RSPA issued a final rule that 
substantially revised the part 195 regulations for breakout tanks.\7\ 
The final rule incorporated 13 consensus industry standards by 
reference for the design, construction, testing, repair, alteration, 
and replacement of breakout tanks. One of those standards was the 2nd 
edition of API Std 653, which RSPA incorporated into an amended version 
of Sec.  195.432 as an alternative to the annual calendar year 
inspection traditionally required.\8\ Then, in 2010, PHMSA incorporated 
by reference the 3rd edition of API Std 653.\9\ Because the 3rd edition 
was the first to include RBI procedures, this amendment had the effect 
of authorizing operators to perform RBI inspections under section 6.4 
of API Std 653.

    \9\ Pipeline Safety: Periodic Updates of Regulatory References 
to Technical Standards and Miscellaneous Edits, 75 FR 48593 (Aug.

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

    In 2015, PHMSA issued a final rule that, among other things, 
incorporated updated editions of certain referenced consensus industry 
standards and made other miscellaneous amendments to part 195. PHMSA 
retained the 3rd edition of API Std 653 in the final rule, which had 
been incorporated by reference in an earlier rulemaking proceeding,\10\ 
but amended Sec.  195.432 to prohibit the use of the RBI procedures 
authorized in that standard for determining alternative internal 
inspection intervals. PHMSA justified that prohibition by pointing to 
concerns with the RBI procedures in API Std 653, particularly use of 
certain discretionary language and provisions allowing an operator to 
exceed prescriptive limits on predicted bottom plate metal loss or 
extend the 20-year inspection interval.\11\
---------------------------------------------------------------------------

    \10\ Pipeline Safety: Periodic Updates of Regulatory References 
to Technical Standards and Miscellaneous Amendments, 80 FR 168, 171 
(Jan. 1, 2015). PHMSA incorporated the 3rd edition of API Std 653 by 
reference in a 2010 final rule, which also made a minor editorial 
correction to align Sec.  195.432 with the updated provisions in 
that standard. Pipeline Safety: Periodic Updates of Regulatory 
References to Technical Standards and Miscellaneous Edits,75 FR 
48593, 48600, 48605 (Aug. 11, 2010).
    \11\ 80 FR at 171, 185.
---------------------------------------------------------------------------

    PHMSA did not analyze separately the costs, benefits, or other 
impacts of prohibiting the use of the RBI procedures in API Std 653 in 
the final rule. Rather, PHMSA simply stated that it was ``making non-
substantive edits and clarifying regulatory language in certain 
provisions,'' and that ``[s]ince these editorial changes are relatively 
minor, this rule would not require pipeline operators to undertake 
significant new pipeline safety initiatives and would have negligible 
cost implications.'' \12\

    DOT and PHMSA recently asked interested stakeholders to submit 
ideas to support Presidential deregulatory and energy policy 
priorities. In April 2025, DOT published a request for information 
(RFI), titled Ensuring Lawful Regulation; Reducing Regulation and 
Controlling Regulatory Costs, 90 FR 14593 (Apr. 3, 2025), and PHMSA 
published an Advance Notice of Proposed Rulemaking (ANPRM) titled 
Pipeline Safety: Mandatory Regulatory Reviews to Unleash American 
Energy and Improve Government Efficiency, 90 FR 23660 (June 4, 2025). 
In response to the DOT RFI, API and the Liquid Energy Pipeline 
Association (LEPA) submitted a joint comment that included a request 
for PHMSA to update API Std 653 to the latest edition and authorize the 
use of RBI procedures.\13\ In response to PHMSA's Unleashing American 
Energy ANPRM, an anonymous individual recommended that PHMSA update 
references to API Std 653 to the most recent version.\14\

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

    On May 21, 2025, PHMSA published an ANPRM titled Pipeline Safety: 
Repair Criteria for Hazardous Liquid and Gas Transmission Pipelines, 90 
FR 21715, which included a request for comment on the inspection 
requirements for breakout tanks. Several commenters addressed the 
breakout tank inspection requirements in responding to the ANPRM, 
including a joint comment from API, LEPA, GPA Midstream Association, 
and the American Fuel & Petrochemical Manufacturers (the Associations), 
and comments from the Colonial Pipeline Company, Enterprise Products 
Operating LLC, Marathon Pipe Line LLC, International-Matex Tank 
Terminals LLC, California Resources Corporation, and the Pipeline 
Safety Trust (PST). Commenters generally supported updating API Std 653 
to the latest edition and authorizing the use of RBI procedures.\15\ 
The Associations noted the U.S. Environmental Protection Agency does 
not restrict the use of RBI under the Spill Prevention, Control, and 
Countermeasures rules in 40 CFR part 112, and cited significant costs, 
environmental impacts, and worker safety hazards associated with 
unnecessary internal inspections of tanks. The Associations estimated 
quantified annual cost savings of $220 million based on an average 
assessment interval and described improved safety performance from 
operators that have applied RBI principles to plant piping at 
refineries and other facilities.\16\ Individual operators provided 
similar comments on the costs and consequences of internal inspections 
and recommended allowing RBI procedures in accordance with recent 
editions of API Std 653.\17\ PST supported extending the inspection 
intervals using RBI to mitigate risk to workers when preparing for and 
conducting inspections, but recommended additional robotic inspection 
conditions.\18\

III. Discussion

    Consistent with the comments and policies described above, PHMSA 
proposes to revise Sec.  195.3 to update

[[Page 32921]]

references to API Std 653; to revise Sec.  195.432 to authorize the use 
of RBI procedures with upper limits on the alternative internal 
inspection intervals; and to make other conforming revisions to part 
195.

A. Incorporation by Reference: Update API Std 653 From the 3rd Edition 
to the 5th Edition

    PHMSA proposes to add API Standard 653, ``Tank Inspection, Repair, 
Alteration, and Reconstruction,'' 5th edition, November 2014, 
(including addendum 1 (April 2018), addendum 2 (May 2020), addendum 3 
(November 2023), errata 1 (March 2020), errata 2 (February 2025), and 
addendum 4 (July 2025)), to the list of incorporated-by-reference 
documents at Sec.  195.3(b)(18). This updated edition would replace 
existing references to the 3rd edition of API Std 653, as issued in 
December 2001 with addenda and errata issued through April 2008.\19\ 
After the incorporation, operators would be required to follow the 
specified requirements in the 5th edition of API Std 653 in complying 
with the requirements for the repair, alteration, and reconstruction of 
breakout tanks in Sec. Sec.  195.205(b) and 195.307(d), and the 
periodic inspection requirements for atmospheric and low-pressure 
aboveground storage tanks in Sec.  195.432 (addressed in section III.B 
below).
---------------------------------------------------------------------------

    \19\ API Standard 653, Tank Inspection, Repair, Alteration, and 
Reconstruction (3rd ed. Dec. 2001). All references to the 3rd 
edition of API Std 653 in this document include addendum 1 
(September 2003), addendum 2 (November 2005), addendum 3 (February 
2008), and errata (April 2008).
---------------------------------------------------------------------------

    As noted in comments submitted by API and LEPA in responding to the 
Repair Criteria ANPRM, the 5th edition of API Std 653 has several 
revisions from the 3rd edition of API Std 653 to incorporate new or 
improved technologies and practices for inspection, examination, and 
repair of breakout tanks. PHMSA has preliminarily determined that these 
changes enhance safety, improve operational efficiency and flexibility, 
and improve clarity. Among the most comprehensive changes since the 3rd 
edition are the incorporation of new requirements in section 9.2.4 for 
door sheets cut out of the tank to provide temporary access to the 
interior of the tank. These new requirements, which cover the design, 
temporary stiffening, inspection, and restoration of door plates ensure 
that the removal, reinstallation, or replacement of the door sheet does 
not compromise the integrity of the tank. Safety-enhancing changes 
include prohibiting door sheets from crossing vertical riveted and lap 
welded seams, special design and inspection requirements for door 
sheets that cross horizontal seams, and consideration for welds near 
riveted seams in order to prevent heat-related leakage.
    Section 9.10.2.2 was also redrafted, covering requirements for 
installing new bearing plates supporting the weight of the tank roof 
when the tank bottom plate is replaced. The requirements are intended 
to minimize risks from wear and corrosion of the tank bottom from 
bearing plates. The 5th edition has introduced more specific design and 
material requirements for bearing plates based on whether the roof is 
steel or aluminum, which influences both wear and corrosion risk. This 
provides a higher level of safety for tanks with steel roofs while 
allowing more flexible design for those with lighter aluminum roofs 
unless there is evidence that certain designs would introduce corrosion 
threats. The guidelines for performing settlement analysis in Annex B 
were also overhauled in the 4th edition to adopt additional modern 
evaluation methods that PHMSA expects will improve operators' 
evaluation of settlement and the resulting strains it puts on tanks.
    In addition to the more significant revisions affecting repair, 
alteration, and reconstruction, cumulative edits since the 3rd edition 
include a number of minor revisions and clarifications that enhance the 
legibility and enforceability of the standard. These include 
clarifications regarding as-built standards, adopting a definition for 
``reconstruction,'' and revising cross references to other sections or 
secondary references to be more specific. Similarly, revisions since 
the 3rd edition regarding the applicability of hydrostatic testing 
requirements in section 12.3 simplify its structure and provide more 
clarity regarding when hydrostatic testing for ``major repairs or major 
alterations'' is required. In general, hydrostatic testing continues to 
be required for tanks that have been reconstructed, undergone major 
repairs or alterations, experienced certain operational changes, or 
been damaged.

B. Physical Inspection Requirements and Risk-Based Inspection (Sec.  
195.432)

    Section 195.432 references API Std 653 to define periodic 
inspection requirements for atmospheric and low-pressure steel above-
ground breakout tanks. Section 6 of the 3rd edition of API Std 653 
requires routine in-service inspections, external inspections, external 
ultrasonic thickness measurements of the tank shell, exterior cathodic 
protection surveys of the tank bottom (if applicable), and internal 
inspections of the tank bottom and shell. These inspections are 
intended to monitor the physical condition of the storage tank, 
particularly to measure the extent and rate of corrosion of the tank 
bottom and shell. The 3rd edition of API Std 653 also establishes a 
minimum frequency for these inspections, but the standard requires an 
operator to consider other factors when determining the inspection 
interval. The requirements for routine in-service inspections, external 
inspections, ultrasonic thickness inspections, and cathodic protection 
surveys are unchanged since the 3rd edition and would therefore not be 
affected by this proposed rule.
    Internal inspections of in-service breakout tanks are the most 
consequential of the required physical inspections because the tank 
usually must be taken out of service and cleaned, and the interior of 
the tank must be accessed to perform the inspection. Section 6.4.2.1 of 
the 3rd edition of API Std 653 requires operators to determine the 
internal inspection interval when not applying RBI based on comparing 
measured corrosion growth rates against the minimum required bottom 
thickness in Table 6-1, but with a maximum internal inspection interval 
of 20 years, or 10 years when the corrosion growth rates are not known 
per section 6.4.2.2. While section 6.4.3 of the 3rd edition of API Std 
653 provides for an alternative internal inspection interval based on 
RBI procedures that allow an operator to extend the internal inspection 
interval beyond 20 years based on the result of the RBI analysis, Sec.  
195.432(b) prohibits the application of the RBI-based alternative 
inspection interval.
    Based on PHMSA's review of improvements to the RBI procedures since 
the 3rd edition of API Std 653 and risk-assessment information provided 
in public comments, PHMSA proposes to revise Sec.  195.432 to authorize 
the use of RBI for determining the internal inspection interval for 
breakout tanks in accordance with the 5th edition of API Std 653. When 
establishing an internal inspection interval, PHMSA proposes a maximum 
timeline of 20 years for performing an initial inspection and a maximum 
reinspection interval of 25 years.\20\ Due to the high cost of 
performing internal inspections, this change will result in cost 
savings and increased uptime for breakout tanks.

[[Page 32922]]

Doubling the time window for performing the initial inspection from the 
current 10-year limit will be particularly impactful. Additional 
safeguards are required in this proposal by PHMSA as a condition for 
the extended inspection interval to ensure appropriate pipeline safety.
---------------------------------------------------------------------------

    \20\ PHMSA requests comment on these time periods and whether 
any new technologies may justify longer maximum timelines, with 
accompanying data.
---------------------------------------------------------------------------

    While the potential impact of a tank bottom failure can be severe 
due to the large volume of product involved, the application of a 
robust RBI is intended to and should minimize the probability of 
failure.\21\ Improvements in the 5th edition of API Std 653, including 
enhanced inspection and repair requirements, credits for installing 
tank safeguards, and more rigorous RBI requirements, reduce the 
probability and potential consequences of a release and improve the 
accuracy of operators' risk analyses. PHMSA is also proposing limits to 
the maximum inspection interval to further reduce risk.
---------------------------------------------------------------------------

    \21\ PHMSA is currently investigating an accident involving the 
estimated release of 9,000 barrels of gasoline through a manmade 
hole in the bottom of an aboveground storage tank in Aston, 
Pennsylvania. See In the Matter of MIPC, LLC, a subsidiary of Monroe 
Energy, LLC, CPF No. 1-2025-048-CAO. The preliminary results of 
PHMSA's investigation do not indicate that the interval for 
conducting an internal inspection of the tank caused or contributed 
to the accident.
---------------------------------------------------------------------------

    API made significant improvements to the 5th edition of API Std 653 
that address concerns raised by PHMSA during the 2015 rulemaking that 
prohibited the application of RBI. The requirements for establishing 
the frequency of internal inspections and RBI requirements in section 
6.4 of the 5th edition of API Std 653 have been rewritten. These 
changes are supplemented by two standalone recommended practices, which 
PHMSA is not proposing to incorporate by reference but are referenced 
in the 5th edition of API Std 653. The first, API Recommended Practice 
580 Elements of a Risk-Based Inspection Program, addresses mandatory 
elements of RBI procedures generally. The second, API Recommended 
Practice 581 Risk-Based Inspection Methodology, provides additional 
guidance on performing a semi-quantitative RBI.\22\
---------------------------------------------------------------------------

    \22\ API, Recommended Practice 580, Elements of a Risk-Based 
Inspection Program (4th ed. Aug. 2023, Addendum 1 Mar. 2025) (API RP 
580); API, Recommended Practice 581, Risk-based Inspection 
Methodology, (4th ed. Jan. 2023) (API RP 581).
---------------------------------------------------------------------------

    Collectively, the changes in the 5th edition of API Std 653 provide 
a more enforceable and rigorous standard with a clearer nexus between 
operator-defined performance targets, and inspection and maintenance 
decision-making. The RBI requirements in section 6.4.2.2.2 of API Std 
653 now reference API RP 580 to define required elements of the 
operator's RBI analysis, and section 6.4.2.2.2.1 and 6.4.2.2.2.2 of the 
5th edition of API Std 653 replaces the list of attributes that 
``should be considered'' with 18 likelihood factors and 13 consequence 
factors that must be evaluated. RBI requirements in section 13 of API 
RP 580 and guidance in API RP 581 provide more information on how to 
use the risk evaluation in the RBI analysis to drive inspection and 
maintenance decision-making. Section 6.4.2.2.2 of the 5th edition of 
API Std 653 defines requirements for developing, reviewing, and 
updating an RBI analysis, including a requirement that the analysis be 
developed by subject matter experts knowledgeable in risk management 
and design construction and maintenance of storage tanks. Finally, 
section 6.4.2.2.2 requires an RBI analysis to be validated, ideally by 
a third party, and reviewed at least once every 10 years or when 
changes to processes, equipment, or consequences warrant a review.
    In addition to improving RBI procedures, the 5th edition 
restructures the inspection interval requirements to better distinguish 
when the initial inspection interval applies and when an operator can 
use an RBI approach to determine the appropriate subsequent internal 
inspections interval. For example, in section 6.4.2.1 of the 5th 
edition of API Std 653, newly installed tank bottoms are subject to a 
more stringent initial inspection interval. However, when an operator 
installs a new bottom on an existing tank, they may apply a longer 
inspection interval only permissible for subsequent inspections 
provided the operator satisfies all the conditions listed in section 
6.4.2.1 (a) through (d). In comparison, section 6.4.2.2 of the 3rd 
edition broadly applies the initial inspection interval to tanks ``when 
corrosion rates are not known and similar service experience is not 
available,'' a standard that is not as well-defined. PHMSA expects that 
more clearly defining when the more stringent initial inspection 
interval is and is not fit for purpose will enhance safety, provide 
regulatory certainty, and result in potential cost savings.
    Section 6.4.2.1.1 of the 5th edition of API Std. 653 prescribes a 
maximum initial inspection interval of 20 years (or 30 years if a 
release prevention barrier is in place), it does not place a time 
limitation on subsequent inspection intervals if an operator is using 
an RBI approach. PHMSA is proposing a different approach.
    The 5th edition of API Std 653 provides direction on selecting 
reliability targets via reference to API RP 580 and API RP 581 but does 
not define what those targets should be. The 5th edition of API Std 653 
and API RP 580 also describe the requirements for performing a rigorous 
risk assessment, but do not prescribe reliability or total consequence 
targets that would anchor the selected inspection interval. In the 
absence of performance targets in the RBI procedures, PHMSA supports a 
reasonable maximum interval for initial and subsequent internal 
inspections. PHMSA proposes a maximum inspection interval of 20 years 
for the initial inspection and 25 years for subsequent inspections. 
PHMSA proposes that these are reasonable maximum intervals as they 
reflect those that had been adopted into API Std 653 and applied by 
industry. The proposed limits correspond to the maximum initial 
inspection interval prescribed in the 5th edition of API Std 653 and 
the maximum interval for subsequent internal inspections for tanks 
without a release prevention barrier that appeared in section 6.4.2.2 
of the 4th edition of API Std 653 prior to 2012.
    Preventing a failure is the main objective of the internal 
inspection program, particularly for the initial inspection that 
establishes the corrosion rate. A release prevention barrier and leak 
detection system can mitigate the consequences of a tank leak but do 
not prevent a tank bottom failure from occurring. Releases into 
containment can still be consequential, and PHMSA expects operators to 
prevent product releases from occurring. While the proposal does not 
allow an operator to extend an inspection interval beyond the maximum 
interval based on the presence of a release prevention barrier, they 
may be considered as part of the RBI risk assessment for initial and 
subsequent inspections, and an operator may credit it as a tank 
safeguard in accordance with Table 6.1 in the 5th edition of API Std 
653. PHMSA seeks comments on whether to set minimum standards for 
reliability or consequences as part of the RBI procedures within the 
regulations.
    Implementation, inspection, and enforcement of RBI procedures 
inherently relies more heavily on the engineering judgement of 
operators and Federal and State inspectors compared with the more 
prescriptive standards for determining an internal inspection interval 
based on corrosion rates. In the 1999 final rule that originally 
adopted API Std 653 and other consensus standards for breakout tanks, 
PHMSA discussed the role of engineering judgment in compliance and 
inspection of programs based on consensus

[[Page 32923]]

standards. PHMSA noted that when a standard, specification, or code 
calls for the use of engineering judgment, PHMSA will not object to the 
use of that judgment but will compare the judgment used by operators to 
make adequate risk-based decisions against what is reasonable under the 
circumstances.\23\ Consistent with that intent, PHMSA retains the 
authority to inspect an operator's RBI analysis and tank inspection 
schedule. If PHMSA finds that an operator's procedures are unreasonable 
or inconsistent with sound engineering judgment or fails to provide an 
adequate minimum level of safety, PHMSA will take appropriate 
enforcement action.

    \23\ Pipeline Safety: Adoption of Consensus Standards for 
Breakout Tanks, 64 FR 15926, 15929 (Apr. 2, 1999).
---------------------------------------------------------------------------

    PHMSA does not propose to adopt the PST recommendation to condition 
the use of RBI on periodic robotic inspection.\24\ PHMSA recognizes the 
value that more frequent, but less invasive, inspections to measure 
corrosion between out-of-service inspections could provide to risk-
based programs for managing breakout tanks. On-stream inspections may 
be especially valuable for establishing a corrosion growth rate early 
in the tank's lifecycle, provided the inspection includes an adequately 
large sample of the tank bottom. PHMSA encourages API to consider 
developing recommended practices for in-service robotic inspections and 
integrating data from such inspections in future editions of API Std 
653. Meanwhile, PHMSA notes that an operator may use the special permit 
process under Sec.  190.341 to evaluate the viability of on-stream 
inspection or other technologies as alternatives to the proposed 
inspection requirements and limitations, subject to PHMSA oversight.

C. Reporting

    PHMSA proposes minor changes to hazardous liquid pipeline 
operators' annual report form (PHMSA Form F7000-1.1) and NPMS 
submission requirements to identify breakout tanks and operators that 
apply RBI. PHMSA will use this information to measure the safety 
performance of breakout tanks using the alternative inspection 
interval. PHMSA also requires this information to plan Federal 
inspections since auditing RBI procedures involves different risks and 
skillsets than evaluating compliance using the more prescriptive 
internal inspection interval.

IV. Availability of Standards Incorporated by Reference

    Pursuant to 49 U.S.C. 60102(p), ``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.'' \25\ PHMSA has 
negotiated an agreement with API to make viewable copies of the 5th 
edition of API Std 653 available to the public at no cost during the 
proceedings for this rulemaking. The standard can be accessed at: 
https://publications.api.org/IBR-Documents-Under-Consideration.aspx. In 
addition, the material can be reasonably obtained by interested parties 
through the applicable publisher contact information listed in Sec.  
195.3 of the amendatory text in this document. Additional information 
regarding the availability of standards PHMSA incorporates by reference 
may be found at https://www.phmsa.dot.gov/standards-rulemaking/pipeline/standards-incorporated-reference.

V. Section-by-Section Analysis

Sec.  195.3 What documents are incorporated by reference partly or 
wholly in this part?

    Section 195.3 lists the documents incorporated by reference into 
part 195. PHMSA proposes to revise Sec.  195.3(b)(18) to incorporate by 
reference the 5th edition of API Std 653 with addenda and errata issued 
through July 2025. This updated edition would replace existing 
references to the 3rd edition of API Std 653 with addenda and errata 
issued through April 2008.
    Upon incorporation, the 5th edition of API Std 653 will apply in 
the following contexts:
     Section 195.205(b): Defining requirements for the repair, 
alteration, or reconstruction of tanks designed for approximate 
atmospheric pressure, constructed of carbon and low alloy steel, welded 
or riveted, and non-refrigerated; and for tanks built to API Std 650 or 
API Std 12C.
     Section 195.307(d): Determining when repair, alteration, 
or reconstruction requires hydrostatic testing for steel atmospheric 
tanks designed for approximate atmospheric pressure, constructed of 
carbon and low alloy steel, welded or riveted, and non-refrigerated; 
and for tanks built to API Std 650 or API Std 12C built after October 
2, 2000.
     Section 195.432(b): Physical inspection requirements for 
atmospheric and low-pressure steel above-ground breakout tanks.
    The updates to the requirements for scheduling the internal 
inspection of breakout tanks, including revising Sec.  195.432 to allow 
RBI, are the most consequential of these changes.

Sec.  195.49 Annual Report

    PHMSA does not propose any amendments to Sec.  195.49 but does 
propose revising part M of the hazardous liquid pipeline annual report 
form (PHMSA Form F7000-1.1) to include a count of tanks managed with 
RBI by volume category.

Sec.  195.61 National Pipeline Mapping System

    PHMSA does not propose any amendments to the NPMS regulations at 
Sec.  195.61. However, PHMSA proposes to require operators to identify 
if a breakout tank is managed with RBI when submitting geospatial 
information about the location of that tank.

Sec.  195.205 Repair, alteration and reconstruction of aboveground 
breakout tanks that have been in service.

    Section 195.205 references API Std 653 for approved repair, 
alteration, and reconstruction procedures for breakout tanks built to 
API Std 650 or its predecessor API Standard 12C. Consistent with 
PHMSA's proposal to allow RBI, PHMSA proposes an editorial amendment to 
remove a parenthetical exclusion of RBI procedures. Since this section 
addresses repair methods rather than internal inspection intervals, 
reference to procedures for establishing periodic internal inspection 
intervals is not necessary regardless of the policy adopted in the 
final rule.

Sec.  195.432 Inspection of in-service breakout tanks

    Section 195.432 requires operators to inspect in-service 
atmospheric and low-pressure steel above-ground breakout tanks 
physically in accordance with API Std 653. In addition to updating the 
edition of API Std 653 that is incorporated by reference in this 
section to the 5th edition, PHMSA proposes removing the prohibition on 
using RBI procedures to determine the interval for internal inspections 
of breakout tanks. PHMSA proposes allowing an operator to determine an 
internal inspection interval based on an RBI analysis carried out in 
accordance with the 5th edition of API Std 653, provided the operator 
retains records necessary to reproduce the analysis, including

[[Page 32924]]

information for each required likelihood and consequence factor listed 
in API Std 653. In addition, PHMSA proposes a maximum internal 
inspection interval of 20 years for the initial inspection and 25 years 
for subsequent internal inspections.
    Since the deadlines for performing a new internal inspection have 
passed, and RBI would be authorized under the NPRM, PHMSA proposes to 
remove the regulations in Sec.  195.432(b)(1) and (2).

VI. Regulatory Analyses and Notices

A. Regulatory Planning and Review--Executive Orders 12866 and 14192, 
DOT Orders 2100.6B and 2100.7, and the Pipeline Safety Laws

    As required by Executive Order (E.O.) 12866 (Regulatory Planning 
and Review; 58 FR 51735 (Oct. 4, 1993)) and DOT Order 2100.6B (Policies 
and Procedures for Rulemaking), the Office of Information and 
Regulatory Affairs (OIRA) within the Executive Office of the 
President's Office of Management and Budget (OMB) has reviewed this 
proposed rule and determined that it is an economically significant 
regulatory action pursuant to E.O. 12866, along with being a ``major 
rule'' as defined by the Congressional Review Act (5 U.S.C. 801 et 
seq.).\26\ In addition, this is a deregulatory action under E.O. 14192 
(Unleashing Prosperity Through Deregulation; 90 FR 9065 (Feb. 6, 2025)) 
and OMB guidance, including M-25-20.\27\
---------------------------------------------------------------------------

    \26\ This final rule does not implicate any of the factors 
identified in section 2(a) of E.O. 14219 (Ensuring Lawful Governance 
and Implementing the President's `Department of Government 
Efficiency' Deregulatory Initiative; 90 FR 10583 (Feb. 25, 2025)) 
indicative that a regulation is ``unlawful . . . undermine[s] the 
national interest.''
    \27\ See OMB, M-24-20, Guidance Implementing Section 3 of E.O. 
14192 (Mar. 26, 2025), available at: https://www.whitehouse.gov/wp-content/uploads/2025/02/M-25-20-Guidance-Implementing-Section-3-of-Executive-Order-14192-Titled-Unleashing-Prosperity-Through-Deregulation.pdf.
---------------------------------------------------------------------------

    The Pipeline Safety Laws (49 U.S.C. 60102(b)) require that PHMSA 
``prepare a risk assessment that . . . identifies the costs and 
benefits associated with a proposed regulatory change.'' E.O. 12866, as 
implemented by DOT Order 2100.6B and DOT Order 2100.7, 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.'' In arriving at those conclusions, E.O. 12866 
requires that agencies should consider ``both quantifiable measures . . 
. and qualitative measures of costs and benefits that are difficult to 
quantify'' and ``maximize net benefits . . . unless a statute requires 
another regulatory approach.''
    Consistent with 49 U.S.C. 60102, E.O. 12866, and DOT Orders 2100.6B 
and 2100.7, PHMSA conducted a preliminary risk assessment of the 
economic impact of this proposed rule in a preliminary regulatory 
impact analysis (PRIA) that is available in the docket for this 
rulemaking. The PRIA details the costs, cost savings, and benefits of 
this proposed rule. PHMSA has determined the cost savings and benefits 
of the proposed rule justify any associated costs notwithstanding the 
uncertainties identified.
    PHMSA expects this proposed rule will result in significant cost 
savings by reducing regulatory burdens and regulatory uncertainty for 
hazardous liquid pipeline operators by incorporating by reference the 
5th edition of API Std 653 and authorizing RBI. At a seven percent 
discount rate, PHMSA estimates that reducing the frequency of initial 
and subsequent internal inspections of breakout tanks based on the 
results of an RBI analysis will save between $29.3 million to $150.1 
million annually, or between $24.5 to $125.7 million annually using a 
three percent discount rate. PHMSA expects these cost savings also will 
result in reduced costs for the public, to whom hazardous liquid 
pipeline operators generally transfer a portion of their compliance 
costs. Those reduced costs to pipeline operators and the public are 
consistent with E.O. 14192, which establishes a Federal policy of 
alleviating ``unnecessary regulatory burdens'' by reducing compliance 
costs and reducing the risks from non-compliance with burdensome 
regulations.
    In addition to those quantified cost savings, PHMSA expects this 
proposed rule will have non-quantified benefits to public safety and 
the environment arising from avoiding the environmental impacts and 
workplace safety risks associated with unnecessary internal 
inspections. In addition, PHMSA expects unquantified benefits to 
pipeline operators and their customers from reducing downtime of tank 
facilities required to perform internal tank inspections.

B. Energy-Related Executive Orders 13211, 14154, and 14156

    The President has declared in E.O. 14156 (Declaring a National 
Energy Emergency; 90 FR 8353 (Jan. 29, 2025)) a national emergency to 
address the inadequate energy development, production, transportation, 
refining, and generation capacity of the United States. Similarly, E.O. 
14154 (Unleashing American Energy; 90 FR 8353 (Jan. 29, 2025)) asserts 
a Federal policy to unleash American energy by ensuring access to 
abundant supplies of reliable, affordable energy from (inter alia) the 
removal of ``undue burden[s]'' on the identification, development, or 
use of domestic energy resources. PHMSA finds this proposed rule is 
consistent with each of E.O. 14156 and E.O. 14154. The proposed rule 
will give hazardous liquid pipeline operators the flexibility to 
establish internal inspection intervals based on a risk analysis. That 
increased regulatory flexibility will in turn increase the 
transportation capacity and reliability for petroleum and petroleum 
products, and improve hazardous liquid pipeline operators' ability to 
provide abundant, reliable, affordable energy products in response to 
consumer and industrial demand.
    However, while this proposed rule is a significant action under 
E.O. 12866, it is not a ``significant energy action'' under E.O. 13211 
(Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use; 66 FR 28355 (May 22, 2001)). The proposal 
will not have a significant adverse effect on supply, distribution, or 
energy use, as further discussed in the PRIA.

C. Executive Order 13132: Federalism

    PHMSA analyzed this proposed rule in accordance with the principles 
and criteria contained in E.O. 13132 (Federalism; 64 FR 43255 (Aug. 10, 
1999)) and the Presidential Memorandum (Preemption; 74 FR 24693 (May 
22, 2009)). While the proposed rule may operate to preempt some State 
requirements, it would 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. Section 
60104(c) of Federal Pipeline Safety Laws prohibits certain State safety 
regulation of interstate pipelines. Under Federal Pipeline Safety Laws, 
States that have submitted a current certification under section 
60105(a) can augment Federal pipeline safety requirements for 
intrastate pipelines regulated by PHMSA but may not approve safety 
requirements less stringent than those required by Federal law. A State 
may also regulate an intrastate pipeline facility that PHMSA does not 
regulate. In that instance, the preemptive effect of the proposed rule 
would be limited to the minimum level necessary to achieve the 
objectives of the statutory authority under which the proposed rule is

[[Page 32925]]

promulgated. Therefore, the consultation and funding requirements of 
E.O. 13132 do not apply.

D. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 603) requires Federal 
agencies to consider the impact of their rules on small entities, to 
analyze alternatives that minimize those impacts, and to make their 
analyses available for public comment. Regulatory flexibility analysis 
is not required, however, where the agency head certifies that the 
rule, if promulgated, will not have a significant economic impact on a 
substantial number of small entities. DOT's implementing guidance--
established consistent with E.O. 13272 (Proper Consideration of Small 
Entities in Agency Rulemaking; 67 FR 53461 (Aug. 16, 2002))--is 
available online at https://www.transportation.gov/regulations/rulemaking-requirements-concerning-small-entities.
    PHMSA has considered the anticipated impact that this rule would 
have and certifies that, if adopted, it will not have a significant 
economic impact on a significant number of small entities. See 5 U.S.C. 
605. The proposal allows the use of RBI procedures to schedule initial 
and subsequent internal inspections within defined technical and safety 
limits under API Standard 653, while preserving existing compliance 
pathways for operators that elect not to use RBI. The proposed rule's 
main impacts are cost savings resulting from additional flexibility to 
extend the interval between internal inspections where a risk 
assessment demonstrates that a longer interval is justified given 
safeguards in place. The cost savings and regulatory flexibility from 
the proposed rule equally will apply to all entities who may elect to 
use an RBI procedure and do not disproportionately affect small 
entities. See SBA, How to Comply with the Regulatory Flexibility Act, 
table 1 (Aug. 2017), available at: https://advocacy.sba.gov/wp-content/uploads/2019/06/How-to-Comply-with-the-RFA.pdf. The cost savings and 
regulatory flexibility from this proposed rule should reduce burdens on 
small entities, as with other operators, and PHMSA does not expect this 
proposed rule adversely to impact small entities. See DOT, Rulemaking 
Requirements Concerning Small Entities (May 18, 2012), available at: 
https://www.transportation.gov/regulations/rulemaking-requirements-concerning-small-entities. Moreover, use of the RBI approach that would 
be permitted by this rule remains elective by those small entities who 
choose it, and the rule does not impact an operator that does not wish 
to employ these procedures. Accordingly, a regulatory flexibility 
analysis was not prepared, though PHMSA is requesting comment on the 
certification.

E. Unfunded Mandates Reform Act of 1995 (UMRA)

    UMRA (2 U.S.C. 1501 et seq.) requires agencies to assess the 
effects of Federal regulatory actions on State, local, and Tribal 
governments, as well as the private sector. UMRA establishes a 
statutory threshold requiring additional analysis for mandates on the 
private sector of $100 million or more in 1996 dollars ($203 million in 
2024 dollars) in any given year. As explained further in the PRIA, 
PHMSA does not expect that the proposed rule will impose unfunded 
mandates under the UMRA.

F. National Environmental Policy Act

    The National Environmental Policy Act (NEPA, 42 U.S.C. 4321 et 
seq.) requires that Federal agencies assess and consider the impacts of 
major Federal actions on the human and natural environment. PHMSA has 
prepared a draft environmental assessment (DEA) considering the 
reasonably foreseeable environmental impacts of the proposed rule. A 
copy is available in the docket for this rulemaking. PHMSA invites 
comments on the environmental impacts of this proposed rule. Following 
the public comment period, PHMSA will consider substantive comments 
before making a final determination. All comments received during this 
period will be addressed and included in the final NEPA document.

G. Executive Order 13175

    PHMSA analyzed this proposed rule according to the principles and 
criteria in E.O. 13175 (Consultation and Coordination with Indian 
Tribal Governments; 65 FR 67249 (Nov. 9, 2000)) and DOT Order 5301.1A 
(Department of Transportation Tribal Consultation Policies and 
Procedures), which require agencies to assure meaningful and timely 
input from Tribal government representatives when developing rules that 
significantly or uniquely affect Tribal communities by imposing 
``substantial direct compliance costs'' or ``substantial direct 
effects'' on such communities, or the relationship or distribution of 
power between the Federal Government and Tribes.
    PHMSA assessed the impact of the proposed rule and does not expect 
it will affect Tribal communities or Indian Tribal governments 
significantly or uniquely, such that the consultation requirements of 
E.O. 13175 and DOT Order 5301.1A do not apply. The proposed 
rulemaking's regulatory amendments have a broad, national scope and 
should not affect Tribal communities significantly or uniquely, much 
less impose substantial compliance costs on Native American Tribal 
governments or mandate Tribal action. Further, consultation with 
stakeholders was made available under E.O. 12866.

H. Paperwork Reduction Act

    The Paperwork Reduction Act (44 U.S.C. 3501 et seq.) and its 
implementing regulations at 5 CFR 1320.8(d) requires that interested 
members of the public and affected agencies have an opportunity to 
comment on information collection and recordkeeping requests. The 
following provisions of this rulemaking will result in minor changes to 
report forms and trigger recordkeeping requirements when an operator 
chooses to use RBI.
    First, PHMSA proposes to revise the hazardous liquid pipeline 
annual report form (PHMSA Form F7000.1-1) to include a count of tanks 
managed under RBI. Second, PHMSA proposes to require the operator to 
identify if a breakout tank is managed under RBI when submitting 
geospatial information on breakout tanks to the National Pipeline 
Mapping System in accordance with Sec.  195.61. Third, operators who 
elect to use an RBI would have to make and retain records documenting 
the risk assessment in accordance with the 5th edition of API Std 653.
    PHMSA will submit information collection requests to OMB for 
approval based on the requirements in this rule. The following 
information is provided for each information collection request: (1) 
title of the information collection; (2) OMB control number; (3) 
current expiration date; (4) type of request; (5) abstract of the 
information collection activity; (6) description of affected public; 
(7) estimate of total annual reporting and recordkeeping burden; and 
(8) frequency of collection. Requests for a copy of these information 
collection requests should be directed to Angela Hill by email at 
[email protected].
    The information collection burden is estimated as follows:
    1. Title: Hazardous Liquid Pipeline Operator Annual Reports.
    OMB Control Number: 2137-0614.
    Current Expiration Date: 03/31/2026.
    Type of Request: Revision.
    Abstract: This mandatory information collection requires the 
operators to submit data on the preceding year electronically by June 
15th of each

[[Page 32926]]

calendar year. This information is used by PHMSA to identify trends in 
hazardous liquid pipeline accidents and to identify operators who have 
poor safety records. PHMSA is revising the hazardous liquid pipeline 
annual report form (PHMSA Form F7000.1-1) to include a count of 
breakout tanks managed under RBI.
    Affected Public: Owners and operators of hazardous liquid 
pipelines.
    Annual Reporting Burden:
    Total Annual Responses: 950.
    Total Annual Burden Hours: 18,050.
    Frequency of Collection: Annually.
    2. Title: National Pipeline Mapping Program.
    OMB Control Number: 2137-0596.
    Current Expiration Date: 3/31/2026.
    Type of Request: Revision.
    Abstract: The Pipeline Safety Improvement Act of 2002 (Pub. L. 107-
355), 49 U.S.C. 60132, ``National Pipeline Mapping System,'' requires, 
the operator of a pipeline facility (except distribution lines and 
gathering lines) to provide information to PHMSA. Each operator is 
required to submit geospatial data appropriate for use in the National 
Pipeline Mapping System or data in a format that can be converted to 
geospatial data; the name and address of the person with primary 
operational control (to be known as its operator); and a means for a 
member of the public to contact the operator for additional information 
about the pipeline facilities it operates. This revision will require 
operators to identify if a breakout tank is managed under RBI when 
submitting geospatial information on breakout tanks to the National 
Pipeline Mapping System in accordance with Sec.  195.61. The new data 
elements will strengthen the effectiveness of PHMSA's risk rankings and 
evaluations, which are used as a factor in determining pipeline 
inspection priority and frequency; allow for more effective assistance 
to emergency responders by providing them with a more reliable, 
complete data set of pipelines and facilities; and provide better 
support to PHMSA's inspectors by supplying more accurate pipeline 
locations and additional pipeline-related geospatial data that can be 
linked to tabular data in PHMSA's inspection database.
    Affected Public: Owners and operators of gas transmission pipeline 
systems.
    Annual Reporting Burden:
    Total Annual Responses: 1,346.
    Total Annual Burden Hours: 162,208.
    Frequency of Collection: Annual.
    3. Title: Transportation of Hazardous Liquids by Pipeline: Record 
keeping and Accident Reporting.
    OMB Control Number: 2137-0047.
    Current Expiration Date: 04/30/2026.
    Type of Request: Revision.
    Abstract: This mandatory information collection covers the 
recordkeeping requirements and the collection of accident data from 
operators of hazardous liquid and carbon dioxide pipelines. Part 195 
requires hazardous liquid operators to file an accident report as soon 
as practicable, but not later than 30 days after discovery of the 
accident on form ``PHMSA F 7000-1'' whenever there is a reportable 
accident. Sec.  195.52 requires operators of hazardous liquid and 
carbon dioxide pipeline systems to make immediate telephonic or online 
notice to the National Response Center (NRC) in the event of a 
reportable accident. PHMSA proposes to require operators who elect to 
use an RBI to make and retain records documenting the risk assessment 
in accordance with the 5th edition of API Std 653. PHMSA estimates that 
operators of 211 breakout tanks will elect to use RBI procedures, with 
operators needing approximately 480 hours to develop a plan for each 
tank. The 5th edition of API Std 653 requires operators to review and 
approve these plans at least once every 10 years, or when warranted by 
process, equipment, or consequence changes. PHMSA estimates that three 
operators per year will spend one hour reviewing RBI plans. 
Accordingly, PHMSA is revising the recordkeeping burden of this 
information collection to account for this added burden.
    Affected Public: Operators of hazardous liquid and carbon dioxide 
pipeline facilities.
    Annual Reporting and Recordkeeping Burden:
    Estimated number of responses: 1,860.
    Estimated annual burden hours: 155,060 hours.
    Frequency of Collection: On occasion.
    Comments on these information collections are invited on: (a) the 
need for the proposed collection of information for the proper 
performance of the functions of the agency; (b) ways to enhance the 
quality, utility, and clarity of the information to be collected; (c) 
ways to minimize the burden of information collection on those who are 
to respond, including the use of appropriate automated, electronic, 
mechanical, or other technological collection techniques; and (d) the 
accuracy of the agency's estimate of the burden of the revised 
collection of information. Send comments to the Office of Management 
and Budget, Office of Information and Regulatory Affairs, Attn: Desk 
Officer for the Department of Transportation, 725 17th Street NW, 
Washington, DC 20503. Submitted comments on or before August 3, 2026.

I. Executive Order 13609 and International Trade Analysis

    E.O. 13609 (Promoting International Regulatory Cooperation; 77 FR 
26413 (May 4, 2012)) requires agencies to consider whether the impacts 
associated with significant variations between domestic and 
international regulatory approaches are unnecessary or may impair the 
ability of American business to export and compete internationally. 
Similarly, the Trade Agreements Act of 1979 (Pub. L. 96-39, as amended 
by Pub. L. 103-465), prohibits Federal agencies from establishing any 
standards or engaging in related activities that create unnecessary 
obstacles to the foreign commerce of the United States. The statute 
also requires consideration of international standards and, where 
appropriate, that they be the basis for U.S. standards. While PHMSA 
engages with international standards setting bodies to protect the 
safety of the American public, PHMSA has determined that the proposed 
regulatory amendments will not cause unnecessary obstacles to foreign 
trade.

J. Cybersecurity and Executive Order 14028

    E.O. 14028 (Improving the Nation's Cybersecurity; 86 FR 26633 (May 
17, 2021)) directs the Federal Government to improve its efforts to 
identify, deter, and respond to ``persistent and increasingly 
sophisticated malicious cyber campaigns.'' PHMSA has considered the 
effects of the proposed rule and expects that its regulatory amendments 
would not affect materially the cybersecurity risk profile for pipeline 
facilities or require pipeline operators to generate new security-
sensitive records. This rule provides an additional option that 
pipeline operators may choose to schedule internal inspections for 
breakout tanks. Ultimately operators can adopt or decline this option. 
It is highly likely that operators electing it are already familiar 
with operation and maintenance plan requirements and have evaluated 
their cybersecurity risks.
    Further, operators are encouraged to consult ongoing efforts by the 
Transportation Security Administration to strengthen cybersecurity and 
resiliency in the pipeline sector, and review cybersecurity guidance 
for pipeline operators issued by the Cybersecurity & Infrastructure 
Security Agency and the Pipeline Cybersecurity Initiative, which 
conduct ongoing activities to address cybersecurity risks

4. Revise Sec.  195.432(b) to read as follows:


Sec.  195.432   Inspection of in-service breakout tanks.

* * * * *
    (b) Each operator must inspect the physical integrity of in-service 
atmospheric and low-pressure steel above-ground breakout tanks 
according to API Std 653 (incorporated by reference, see Sec.  195.3). 
In order to use Risk Based Inspection (RBI) procedures in API Std 653, 
the operator must make and retain records for all of the likelihood and 
consequence factors listed in section 6.4.2.2.2.1 and 6.4.2.2.2.2 of 
API Std 653 and other data used in the RBI assessment. The internal 
inspection intervals established under 6.4.2 of API Std 653 may not 
exceed 20 years for the initial inspection and 25 years for subsequent 
internal inspections. If structural conditions prevent access to the 
tank bottom, its integrity may be assessed according to a plan included 
in the operations and maintenance manual under Sec.  195.402(c)(3).
