III. Background, Basis, and Purpose

    This notice of proposed rulemaking (NPRM) incorporates by reference 
updated marine engineering standards in Title 46 of the Code of Federal 
Regulations (CFR) subchapter F, including standards for boilers, 
pressure vessels, auxiliary machinery, piping, valves, and fittings, 
for various types of vessels; adds a limited number of alternative 
standards; and eliminates outdated or unnecessarily prescriptive 
regulations.
    The Office of Management and Budget (OMB) directs, via OMB Circular 
A-119, that federal agencies use industry-based voluntary consensus 
standards in lieu of government-unique requirements where appropriate. 
The Coast Guard actively participates in the development of industry 
standards of safety for marine equipment at the International Maritime 
Organization (IMO), the International Organization for Standardization 
(ISO), ASTM International (ASTM), American Society of Mechanical 
Engineers (ASME), and other standards-setting bodies that belong to the 
American National Standards Institute (ANSI). Recently published 
editions of these standards provide necessary updates to materials, 
testing practices, and technologies, enhancing safety and compliance.

[[Page 57897]]

    The United States Coast Guard has statutory authority to promulgate 
regulations under Title 43, United States Code (U.S.C.), section 
1333(d); and Title 46 U.S.C. 3306 and 3703, and the Department of 
Homeland Security Delegation No. 0170.1, which delegates authority 
under these statutes to the Commandant of the Coast Guard. 43 U.S.C. 
1333(d) grants the Secretary the authority to promulgate and enforce 
regulations with respect to lights and other warning devices, safety 
equipment, and other matters relating to the promotion of safety of 
life and property on artificial islands, installations, and other 
devices. 46 U.S.C. 3306(a)(1) authorizes the Secretary to prescribe 
regulations for the design, construction, alteration, repair, and 
operation of vessels subject to inspection, including equipment, 
appliances, propulsion machinery, auxiliary machinery, boilers, unfired 
pressure vessels, piping, and electric installations. Additionally, 46 
U.S.C. 3703(a) grants the Secretary authority to regulate tank vessels 
regarding the construction, alteration, repair, maintenance, operation, 
and equipping of vessels that may be necessary for increased protection 
against hazards to life and property, for navigation and vessel safety, 
and for enhanced protection of the marine environment.

IV. Discussion of Proposed Rule

A. General Discussion

    In general, the proposed rule would make the following changes:
    1. Corrections--we would amend several sections to correct 
inadvertent errors or deletions. We would also remove material that is 
obsolete or superfluous to an efficient and effective marine safety 
regulatory scheme, and update contact information for Coast Guard 
offices and standards organizations.
    2. Stylistic Revisions--we would revise the language of some 
sections, primarily for greater clarity. This includes revising 
sentences containing the word ``shall'' to use ``must'' or another 
grammatically equivalent word or phrase in accordance with plain 
language guidelines, and standardizing terms that were variously 
presented as compound words, hyphenated constructions, or multi-word 
phrases using the format preferred by the Government Publishing Office 
(GPO).
    3. Updated cross references--we would update cross references to 
reflect the relocation, within the CFR, of pertinent provisions. We 
would also standardize designations for tables, figures, notes, and 
formulas using the format preferred by the Office of the Federal 
Register (OFR).
    4. Updated industry standards--we would update cross-references to 
industry standards by adding new references, replacing references to 
superseded standards or editions, and by conforming text accordingly. 
We incorporate these updated standards because they reflect the latest 
available technologies, practices, and procedures that are recommended 
by consensus bodies, ship classification societies and other maritime 
organizations with experience in the industry. As the baseline upon 
which other standards, rules, and equivalency requests are evaluated, 
it is important that subchapter F incorporate up-to-date references. 
The class rules of the American Bureau of Shipping (ABS), in 
particular, are incorporated by reference in multiple locations within 
subchapter F and 46 CFR Chapter I. It is important to note that while 
these rules set the regulatory baseline or standard for specific 
engineering systems and equipment, the Coast Guard has also authorized 
classification societies in accordance with 46 CFR part 8. These 
authorized classification societies are listed on the Coast Guard 
website \1\ and have been delegated the authority to perform certain 
functions and certifications using their respective class rules for 
vessels enrolled in the Alternate Compliance Program. For vessels not 
enrolled in the Alternate Compliance Program, the class rules of an 
authorized classification society may be proposed as an alternative to 
the ABS class rules incorporated by reference for engineering systems 
and equipment. The following table indicates the sections we propose to 
amend, and why.

Sec. Sec.  64.5, 64.11, 64.13, 64.21, 64.25, and 64.31, and reference 
is made to the use of a constant from the 1974 edition in a calculation 
at Sec.  64.63. However, these earlier editions would remain unchanged 
within the CFR, as part 64 is applicable only to marine portable tanks 
for which the Coast Guard's Marine Safety Center (MSC) received an 
application on or before May 1, 1991. This code contains requirements, 
specific prohibitions, and non-mandatory guidance for construction of 
pressure vessels. It has been regularly revised to accommodate 
technological developments, to address administrative requirements, to 
incorporate interpretations, and to clarify the intent of the code. It 
is the internationally accepted authoritative standard for design and 
construction of heating boilers. Incorporating the latest editions 
ensures compliance with current industry practices. The 2019 edition 
allows for additional design methods from Div. 2 to be used in Div. 1 
by creating new appendix 46. Revisions were also made for clarity.

Appliances, 2008. This standard updates the 1997 edition currently 
incorporated by reference at Sec.  63.15-3. This standard establishes 
requirements for pumps intended for use as part of oil-burning 
appliances or installed in fuel-oil piping systems serving equipment. 
It has been regularly revised to accommodate technological 
developments, to address administrative requirements, to incorporate 
interpretations, and to clarify the standard intent. It is the 
internationally accepted standard.
     UL 1453, Standard for Safety, Electric Booster and 
Commercial Storage Tank Water Heaters, Sixth Edition, 2016. This 
standard would replace the 1995 standard, currently incorporated by 
reference at Sec. Sec.  53.01-10 and 63.25-3. This standard contains 
requirements for electric booster water heaters, electric commercial 
storage tank water heaters, and remote control assemblies for such 
heaters, rated 600 volts or less, that are over 120 gallons

[[Page 57912]]

(454 L) in capacity, rated over 12 kilowatts, or are equipped with one 
or more temperature regulating controls permitting water temperature of 
more than 85[deg]C (185 [deg]F). The 2016 edition provides minor 
technical changes and has been edited for clarity.

C. Standards Previously Approved for Incorporation by Reference

    The following standards were previously approved for incorporation 
by reference and are included in the proposed regulatory text because 
either the current format of the reference does not comply with current 
OFR requirements or the proposed text is a revision that includes an 
existing reference to the standard. We do not propose to change the 
existing IBR approval.

    Replacing the words ``boiler pressure vessel code'' with ``BPVC'' 
throughout all of part 52, as BPVC is recognized as the appropriate 
acronym for the ASME Boiler Pressure Vessel Code.
Section 52.01-52.25 Power Boilers
    Modifying various paragraphs to delete text already addressed in 
ASME BPVC.
Section 52.01-3 Definitions
    Deleting definitions listed in this section but not currently used 
in Part 52 and not needed going forward, as there is no need to define 
a term if it is not used later in the regulatory text. Deleted terms 
include: High temperature water boiler, packaged boiler, Fired steam 
boiler, Hybrid boiler, Shell, Heads, Dished heads, Stayed heads, Water 
wall, Header, Domes, Steam chimneys, Corrugated furnace, Plain furnace,

Bursting disk device, Feed valve, Salinometer cocks, Expanding, 
Beading, Bell mouthing, Telltale hole, Openings, Pressure, Absolute 
pressure, Internal pressure, and External pressure. And, deleting 
Figure 52.01-3--Acceptable Types of Boiler Stays. Figure 52.01-3 is not 
necessary, as the ASME BPVC

[[Page 57913]]

adequately defines the requirements for boiler stayed surfaces.
Section 52.01-50 Fusible Plugs (Modifies A-19 Through A-21)
    Modifying various paragraphs in this section to delete references 
and text already addressed by the ASME BPVC or that are otherwise 
outdated.
Section 52.01-55 Maximum Allowable Working Pressure
    Modifying various paragraphs in this section to delete references 
and text already addressed by the ASME BPVC or that are otherwise 
outdated.
Section 52.01-90 Materials
    Deleting this section. Materials for boiler design are adequately 
addressed by the ASME BPVC.
Section 52.01-105 Piping, Valves, and Fittings
    Modifying various paragraphs in this section to delete references 
and text already addressed by the ASME BPVC or that are otherwise 
outdated.
Section 52.01-110 Water-Level Indicators, Water Columns, Gauge-Glass 
Connections, Gauge Cocks, and Pressure Gauges
    Modifying various paragraphs in this section to delete references 
and text already addressed by the ASME BPVC or that are otherwise 
outdated.
Section 52.01-130 Installation
    Modifying various paragraphs in this section to delete references 
and text already addressed by the ASME BPVC or that are otherwise 
outdated.
Section 52.25-3 Feedwater Heaters (Modifies PFH-1)
    Modifying various paragraphs in this section to delete references 
and text already addressed by the ASME BPVC or that are otherwise 
outdated.
Part 53--Heating Boilers
    Replacing the words ``boiler pressure vessel code'' with ``BPVC'' 
throughout part 53, as BPVC is recognized as the appropriate acronym 
for the ASME Boiler Pressure Vessel Code.
Section 53.01-10 Service Restrictions and Exceptions (Replaces HG-101)
    Modifying paragraph (d) to remove exact temperature requirements 
and retaining a temperature range that would benefit industry.
    Modifying paragraph (e)(1) to provide correct citation for the ASME 
BPVC stamping and provide cites to the IBR.
Part 54--Pressure Vessels
    Replacing the words ``boiler pressure vessel code'' with ``BPVC'' 
throughout all of part 54, as BPVC is recognized as the appropriate 
acronym for the ASME Boiler Pressure Vessel Code.
Section 54.01-1 Incorporation by Reference
    Modifying paragraphs (b), (d), and (e) to update the addresses for 
the American Society of Mechanical Engineers (ASME), the Compressed Gas 
Association (CGA), and the Manufacturers Standardization Society of the 
Valve and Fittings Industry (MSS), respectively.
Section 54.01-15 Exemptions From Shop Inspection Plan Approval 
(Modifies U-1(c)(2))
    Deleting paragraph (a)(3)(i) because this section deals with 
internal pressure and the reference cited deals with external pressure.
Section 54.01-18 Plan Approval
    Editing paragraph (a) to provide reference to new proposed 
paragraph (c).
    Adding paragraph (c) to identify which plans for Class I, II, and 
II pressure vessels are not required to be submitted for approval.
Section 54.10-3 Marine Inspectors (Replaces UG-90 and UG-91, and 
Modifies UG-92 Through UG-103)
    Editing the section heading to make it easier to find the 
regulation requiring stamping of the Coast Guard Symbol. The 
requirement for use of the Coast Guard Symbol on pressure vessels is 
often misunderstood.
    Modifying paragraph (b) to identify when shop inspection is 
required. Part 54 refers to shop inspection of pressure vessels under 
construction in several locations, but the term is not used here.
    Adding new paragraph (c), redesignating existing paragraph (c) as 
new paragraph (d), and removing the requirement for stamping with the 
Coast Guard Symbol. The requirement for use of the Coast Guard Symbol 
on pressure vessels is often misunderstood. By applying the symbol, the 
marine inspector is documenting that the pressure vessel meets Coast 
Guard requirements for pressure vessels on ships. Adding a paragraph 
clarifies which pressure vessels do not require stamping.
Section 54.10-20 Marking and Stamping
    Modifying paragraph (a)(2) to clarify numbering requirements. The 
requirement for Coast Guard numbering of pressure vessels is often 
misunderstood. Numbering is only required when the Coast Guard has 
inspected the pressure vessel during construction (shop inspection).
Part 56--Piping Systems and Appurtenances
Section 56.07-5 Definitions
    Clarifying the definition for ``piping schedule'' and deleting the 
definition for ``plate flange,'' as it does not require a definition.
Section 56.07-10 Design Conditions and Criteria (Modifies 101-104.7)
    Modifying paragraph (b) by deleting the last sentence within the 
parentheses. It is not necessary to refer to definitions in part 52 for 
this paragraph.
    Modifying paragraph (d) by deleting text that was inadvertently 
repeated.
    Modifying paragraph (e) by removing references to specific 
paragraphs and instead referring to the entire subpart.
Section 56.15-1 Pipe Joint Fittings
    Removing text in paragraph (c)(2) that is already adequately 
addressed by the incorporated ASME industry standard.
Section 56.15-5 Fluid-Conditioner Fittings
    Deleting text in paragraph (c), nonstandard fluid conditioner 
fittings, that is already adequately addressed by paragraph (b); 
generally, fluid conditioner fittings must meet the requirements of 
this section regardless of whether they are `standard' or 
`nonstandard', and must be appropriate for the fluid contained, and the 
temperature and pressure of the system. In addition, with advancements 
in manufacturing, there is no need to reference part 54 (pressure 
vessels), for fluid conditioner fittings in current paragraphs (c) and 
(d).
Section 56.20-1 General
    Removing text that is redundant and that can be adequately replaced 
by the incorporated ASME standard.
Section 56.20-9 Valve Construction
    Modifying paragraphs (a), (b), (c), (e), and (g) to reflect 
advancements in valve design technology and to remove text adequately 
addressed already by the incorporated ASME standard.
Section 56.20-15 Valves Employing Resilient Material
    Deleting text that is no longer required and simplifying text to 
reflect current policy employed by the MSC to evaluate these types of 
valves. Overall, these valves are not required anywhere on ships, and 
this section only

[[Page 57914]]

delineates the requirements for when they are installed.

Section 58.25-85 Special Requirements for Tank Vessels
    Deleting certain text in paragraph (c)(1) and (2) of this section 
as unenforceable.
    Deleting paragraph (g), because this paragraph is applicable only 
to tank vessels of 40,000 gross tons or more constructed before 1984. 
Virtually all of those vessels have been phased out of service due to 
the pollution prevention requirements in 33 CFR 157 for ``double 
hulls'' on tank vessels.
Section 58.30-1 Scope
    Deleting certain text in paragraph (a) as not applicable.
Section 58.30-15 Pipe, Tubing, Valves, Fittings, Pumps, and Motors
    Deleting certain text in paragraphs (b) and (d) as redundant, given 
the incorporation of industry standards.

    Removing text in paragraphs (a) and (b) to provide clarity.
Section 59.15-1 Furnace Repairs
    Modifying paragraphs (a), (b), (c) and (e) to eliminate unnecessary 
requirements and to provide clarity for furnace repairs.
Part 61--Periodic Tests and Inspections
Section 61.03-1 Incorporation by Reference
    Modifying paragraph (b) to update the name and address of ASTM 
International.
Section 61.05-10 Boilers in Service
    Eliminating unnecessary and outdated text regarding boiler 
inspections from paragraphs (a) and (f).
Section 61.10-5 Pressure Vessels in Service
    Modifying paragraph (g) to provide inspection compliance options, 
in lieu of the hydrostatic test currently required by this paragraph, 
for bulk storage tanks containing refrigerated liquefied CO2 
for use aboard a vessel as a fire-extinguishing agent. The inspection 
options consist of performing a hydrostatic test or having the option 
of an internal inspection. This is further explained in the regulatory 
language.
Part 62--Vital System Automation
Section 62.05-1 Incorporation by Reference
    Modifying paragraph (b) to update the address for the American 
Bureau of Shipping (ABS).
Section 62.35-50 Tabulated Monitoring and Safety Control Requirements 
for Specific Systems
    Deleting the requirements for main propulsion boiler supply casing 
and uptakes, burner flames, control power, and burner valves in Table 
62.35-50. These components are required to comply with the same 
requirements in Section 4-9-6 of the ABS Marine Vessel Rules (2020), 
which is proposed to be referenced in this table.
    Modifying the requirements for ship service generators in Table 
62.35-50. Currently, compliance with the ABS Steel Vessel Rules for

V. Incorporation by Reference

    Material proposed for incorporation by reference appears in 46 CFR 
parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63, and 64 and is 
summarized in section IV.B of this preamble. For information about how 
to view this material, see the ADDRESSES section of this preamble. 
Copies of the material are also available from the sources listed in 46 
CFR parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63, and 64. Before 
publishing a binding rule, we will submit this material to the Director 
of the Federal Register for approval of the incorporation by reference.

VI. Regulatory Analyses

    We developed this proposed rule after considering numerous statutes 
and Executive Orders related to rulemaking. A summary of our analyses 
based on these statutes or Executive Orders follows.

A. Regulatory Planning and Review

    Executive Orders 12866 (Regulatory Planning and Review) and 13563 
(Improving Regulation and Regulatory Review) direct agencies to assess 
the costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select regulatory approaches that maximize 
net benefits (including potential economic, environmental, public 
health and safety effects, distributive impacts, and equity). Executive 
Order 13563 emphasizes the importance of quantifying costs and 
benefits, reducing costs, harmonizing rules, and promoting flexibility.
    The Office of Management and Budget (OMB) has not designated this 
proposed rule a significant regulatory action under section 3(f) of 
Executive Order 12866. Accordingly, OMB has not reviewed it.
    The Coast Guard proposes to update subchapter F of Title 46 of the 
CFR. This proposed rule would align the standards on U.S.-flagged 
vessels of vessel types of subchapter F with current industry practices 
to ensure that regulatory standards are current, and the changes would 
harmonize regulatory requirements with current industry standards. The 
majority of the updates simply would incorporate by reference the more 
recent versions of the same standards with little or no substantive

[[Page 57917]]

change. In some cases, the more recent editions reflect more modern 
technologies, terminology, and practices. The updates also would 
correct regulatory language and remove redundant and outdated 
references. The Coast Guard believes there are no additional costs 
associated with this proposed rule. The Coast Guard estimates this rule 
will save the regulated public and federal government approximately 
$9.787 million over the 10-year period of analysis at 7% in 2020 
dollars.
    The following regulatory analysis (RA) provides an evaluation of 
the economic impacts associated with this proposed rule. Table 2 
provides a summary of the proposed rule's costs and benefits.

                                        Class societies and vessel
                                        insurers may have some interest.
Costs................................  None. The proposed rule would not
                                        increase costs of compliance for
                                        the regulated public or the
                                        Coast Guard because no
                                        additional requirements are
                                        being proposed.

                                        million in 2020 dollars.
Unquantified Benefits................  Clarity of regulatory intent
                                        through stylistic changes and
                                        corrections, harmonization of
                                        regulatory requirements with
                                        current industry standards,
                                        better utilization of Coast
                                        Guard human resources,
                                        compliance with Presidential
                                        Regulatory Reform Initiative
                                        (March 4, 1995).\2\
------------------------------------------------------------------------

    This proposed rule has two main goals. First, the Coast Guard 
intends it to update design standards that appear in the CFR by 
incorporating by reference more recent industry standards. Second, the 
proposed rule would provide clarity and simplify regulatory compliance 
for industry by removing obsolete regulations and revising current 
regulatory text, including the correction of errors.
---------------------------------------------------------------------------

    \2\ The proposed rule would continue the Coast Guard's response 
to the Presidential Regulatory Reform Imitative of March 4, 1995, 
and directives including Executive Orders 12866 and 13563 that are 
intended to improve regulation and the regulatory process. The 
provisions of this proposed rule would remove outdated regulations, 
revise current regulatory text, and incorporate by reference more 
recent national and international industry standards into the CFR. 
The Coast Guard recognizes the significant technological advances 
technology and equipment which is used or carried on vessels. As a 
result, this proposed rule would encourage the use of newer 
equipment and promote adherence to modern standards in the industry.
---------------------------------------------------------------------------

Affected Population
    The Coast Guard analyzed this rulemaking to determine the affected 
population and how the proposed rule would impact vessel owners and 
manufacturers.\3\ The proposed revisions affect a variety of vessel 
owners and operators; including those owning cargo vessels, passenger 
vessels, nautical school vessels, tank vessels, and tank barges. Some 
potentially impacted vessel owners and operators include nonprofits and 
Tribal/State/local government entities.\4\ Because the proposal impacts 
only new vessels or those undergoing major conversions, the Coast Guard 
estimates that fewer than 200 vessels would be impacted annually.\5\
---------------------------------------------------------------------------

    \3\ Class societies and vessel insurers may have interest in the 
rule. However, no actions are required by them directly or 
indirectly as a result of the rule.
    \4\ Public vessels are excluded.
    \5\ Based on input from Coast Guard subject matter experts in 
the Directorate of Commercial Regulations and Standards who are 
tasked with relevant duties.
---------------------------------------------------------------------------

    An estimated 16,148 vessels owned by 6,437 owners and operators 
would be impacted potentially, but the vessel owners and operators 
would be impacted directly only if they procured a new vessel or 
engaged in a major conversion of an existing vessel under conditions as 
specified in the proposal. Large self-propelled vessels, which are 
covered by more provisions of Subchapter F than smaller vessels and 
barges, would be more likely to be impacted. The following table 
details those vessels potentially impacted by the proposed rule.

  Information for Safety and Law Enforcement (MISLE) database.


[[Page 57918]]

    The proposed rule also would impact businesses involved in vessel 
manufacturing. There are approximately 1,022 shipyards and 
manufacturers of vessels or vessel components in the affected 
population; however, vessel manufacturers are believed to already be in 
voluntary compliance with the proposed changes. In addition, the 
proposal would impact the Coast Guard and its staff in the MSC and CG-
5PS. An estimated six civilian engineers and six uniformed personnel 
potentially would be impacted.
Summary of Changes
    Generally, the Coast Guard proposes to update codified references 
to standards incorporated by reference in subchapter F with their more 
recent editions. These more recent standards would provide more clarity 
and specificity than the outdated standards they would be replacing. 
More specifically, the Coast Guard segments the effect of the proposed 
changes into three categories: (1) Editorial changes to the CFR; (2) 
technical updates to standards incorporated by reference; and (3) 
compliance alternatives to standards incorporated by reference. Based 
on data from industry, the Coast Guard assumes industry already uses 
the more recent standards referenced in the proposal. Table 4 
summarizes the regulatory changes.
    First, for the proposed changes to update standards incorporated by 
reference, this proposed rule would make editorial changes to 
subchapter F that include such items as the removal of outdated 
terminology and the consolidation of text. These proposed changes would 
include 46 CFR parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63 and 64. 
The Coast Guard expects these changes would have no costs, cost 
savings, or benefits.
    Second, this proposed rule updates standards incorporated by 
reference throughout subchapter F. Because no resources are required, 
and because they have been adopted voluntarily already by 
manufacturers, the Coast Guard expects these changes would have no 
cost.
    Third, this proposed rule would amend the regulatory text in 46 CFR 
58.10-5(d)(1) and 61.10-5(g) that impacts compliance alternatives for 
vessel owners and operators. The changes reflect the proposed addition 
of a compliance alternative and the proposed removal of a compliance 
alternative. This proposed change results from the discontinuation of a 
standard incorporated by reference that is the basis of the compliance 
alternative. (Please see the preamble in the proposed changes to ``Part 
61--Periodic Tests and Inspections,'' and further detailed in the Cost 
Savings portion of this RA.) These proposed changes provide regulatory 
flexibility for the regulated public. No additional cost would be 
incurred, and the addition of a compliance alternative may save money. 
The proposed rule's replacement of a compliance alternative would offer 
an option which has lower costs associated with it. This would be a 
cost savings for vessel owners if they choose to use this compliance 
alternative.
    The proposed rule would create consistency between Coast Guard 
regulations and national and international standards through 
incorporation by reference, provide options with alternative standards, 
eliminate obsolete standards, and clarify the existing requirements 
through the changes proposed in 46 CFR subchapter F. Table 4 lists 
these proposed changes by type of change. Readers may consult the 
preamble of this NPRM for a general summary of the proposed changes.
---------------------------------------------------------------------------

    \6\ Please refer to the preamble and Table 1 for a complete 
accounting of affected paragraphs, including redesignations.
    \7\ This list is not exhaustive. Please see Table 1 for the full 
list.
    \8\ Please see Table 1 for complete list.
    \9\ The proposed change would give operators the option of 
undergoing an internal inspection every 10 years as opposed to 
requiring a hydrostatic test every 10 years.
    \10\ UL 1111 has been withdrawn and no longer exists; therefore, 
it can no longer be included as an option for regulation compliance.

Data Input for Calculations
    This RA uses multiple data sources. To estimate the duration of 
tasks, the Coast Guard used previous OMB-approved collections of 
information. These collections of information were previously vetted 
publicly and provide guidance on estimates of tasks such as 
communicating information and education. The RA also uses estimates 
from Coast Guard subject matter experts.

[[Page 57919]]

    To calculate wage rates, the Coast Guard used two publicly 
available sources for wage data: the U.S. Department of Labor Bureau of 
Labor Statistics (BLS) Occupational Employment Statistics and the 
Commandant Instruction entitled ``Reimbursable Standard Rates'' 
(commonly called Commandant Instruction U).\11\ For positions outside 
the Coast Guard, the Coast Guard used publicly available data of the 
BLS Occupational Compensation Survey to estimate wage rates for 
positions that would be impacted by the proposed rule. For Coast Guard 
positions, the Coast Guard used publicly available and publicly vetted 
information found in Commandant Instruction U and the U.S. Office of 
Personnel Management pay chart for the Washington, DC locality pay area 
for 2020 \12\ to estimate the wage data.
---------------------------------------------------------------------------

    \11\ The Instruction is dated February 27, 2020, is numbered 
COMDTINST 7310.1U and commonly is called Commandant Instruction U. 
Enclosure 2 lists the relevant data; please see in-government wage

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

    From the wage data obtained in the previous step, the Coast Guard 
used a loaded labor rate \13\ to estimate the actual cost of labor to 
employers. The load factor (or benefits multipliers) for the regulated 
public and Coast Guard civilian workers was obtained using BLS data. To 
account for an employee's non-wage benefits, the Coast Guard applied a 
load factor to the unloaded mean hourly wage rate; data of the BLS's 
``Employer Cost for Employee Compensation'' database were used for the 
regulated public's wages.\14\ The Coast Guard determined the load 
factor to be about 1.49, rounded. For Coast Guard civilian positions, 
the load factor was determined to be approximately 1.75, rounded.\15\ 
For Coast Guard uniformed positions, the Coast Guard used data that 
already had applied the load factor, so such an adjustment was not 
necessary.\16\ These figures were used to estimate the reasonable and 
customary average labor cost to employers. Table 5 displays the labor 
categories, the source of the wage rates, the total compensation, the 
wage rates, and the calculated load factor. We estimated the load 
factor for the applicable occupation category by dividing the total 
compensation by the hourly wage rate.
---------------------------------------------------------------------------

    \13\ A loaded hourly wage rate is what a company pays per hour 
to employ a person, not the hourly wage an employee receives. The 
loaded hourly wage rate includes the cost of non-wage benefits 
(health insurance, vacation, etc.).
    \14\ To estimate the load factor, the Coast Guard used publicly 
available BLS data (https://www.bls.gov/data/). To recreate these 
calculations, go to the ``Databases, Tables & Calculators'' page, 
select the multi-screen data search feature for ``Employer Costs for 
Employee Compensation'' under ``Pay & Benefits.'' (Alternatively, a 
direct link can also be found at https://data.bls.gov/cgi-bin/dsrv?cm.) For total compensation, in the search field select 
``Private industry workers,'' then ``Total compensation,'' 
``Transportation and material moving occupations,'' ``All workers,'' 
``All workers,'' ``United States (National),'' ``Cost of 
compensation (Cost per hour worked),'' and ``Not Seasonally 
Adjusted.'' For wages and salaries, perform the same steps except 
select ``Wages and salaries'' on the second screen. The series IDs 
for total compensation and wages and salaries are CMU2010000520000D 
and CMU2020000520000D, respectively. Using fourth quarter data for 
2020, the Coast Guard divided the value for total compensation, 
$31.76, by wages and salaries, $21.35, to estimate a load factor of 
approximately 1.49 (rounded to the nearest tenth). Unrounded figures 
were used in calculations.
    \15\ Based on data from the Congressional Budget Office (https://www.cbo.gov/system/files/115th-congress-2017-2018/reports/52637-federalprivatepay.pdf). The report provided estimates for total 
compensation for Federal workers at this educational level to be 
$51.90 per hour with wages of $29.70 per hour, in 2015 dollars. The 
estimated load factor comports with later data as reported by BLS 
(see further for details). Unrounded figures were used in 
calculations.

    The Coast Guard assumed a constant wage rate and a constant 
duration for tasks for the period of annualization.\19\ Likewise, the 
estimates are based on 2020 dollars. Table 6 presents the estimated 
hourly loaded wage rates for the proposed rule.

November 17, 2020. The load factor is found by taking the quotient 
of compensation to benefits as found on Table 2 and 3 of the report. 
Coast Guard used the figures for Federal workers with professional 
degree or doctorate. To verify the accuracy of this load factor 
estimate, the Coast Guard compared it with findings from an analysis 
of BLS total compensation and wage data. The load factor comports 
with the data analysis of BLS Employer Costs for Employee 
Compensation, All workers in Public Administration. The load factor 
was obtained from https://www.bls.gov/web/ecec/ececqrtn.pdf using 
Table 8 for public administration workers (4th Quarter 2020 data). 
The Coast Guard divided the value for total compensation, $51.54 by 
wages and salaries, or $29.54, to obtain a load factor of 
approximately 1.74 (rounded to the nearest tenth). Unrounded figures 
were used in calculations.
    \19\ Some tasks may take less time in the future due to 
technological advances. However, the Coast Guard has assumed no 
change in duration of tasks over the period of annualization.
---------------------------------------------------------------------------

    Using the BLS ``Occupational and Employment Statistics'' database 
and May 2019 wage estimates, the unloaded mean hourly wage rate for 
marine engineers and naval architects (occupational code 17-2121) is 
$47.88.\20\ The Coast Guard multiplied $47.88 by the load factor of 
1.49 to obtain a loaded mean hourly wage rate of about $71.23 for this 
occupation. The hourly rate for a manager (occupational code 11-3051) 
\21\ of $56.82 was estimated to be $84.52 after the load factor 
application.

publicly available data as found in Commandant Instruction U \22\ to 
estimate wage rates for Coast Guard employees. Labor costs attributed 
to the Government are estimated for Coast Guard civilian and uniformed 
engineers and supervisors of CG-5PS and the MSC. Hourly loaded labor 
costs for civilians are estimated \23\ for a GS-14 engineer at $115.51 
and for a GS-15 engineering supervisor at $135.87. For uniformed 
engineers, the Coast Guard used an average of $91 \24\ for engineers at 
the O-3 (Lieutenant) and O-4 level (Lieutenant Commander) because both 
would work on the task. The wage rate for a uniformed supervisory 
engineer is estimated to be $111 for an O-5 (Commander). These figures 
represent a wage rate with a fully-loaded labor factor of 1.85 for 
uniformed Coast Guard positions.\25\ Table 6 presents a summary of the 
data used.

Occupational Code 17-2121 (Marine Engineer and Naval Architect) for 
engineers, Occupational Code 11-3051 for supervisory engineers.

were last viewed on May 25, 2021.
    \29\ The U.S. Office of Personnel Management (OPM) Office of 
Policy, Data and Oversight provides pay data for Federal employees. 
These data were obtained from the 2020 GS Pay Tables using midpoint 
for each pay grade and the Washington-Baltimore-Arlington locality 
pay area. Please see https://www.opm.gov/policy-data-oversight/pay-leave/salaries-wages/salary-tables/pdf/2020/DCB.pdf. The data were 
viewed last on November 18, 2020.
    \30\ See Commandant Instruction U Enclosure 2. This estimate 
previously was used in past Coast Guard rulemakings including the 
proposed and final rules for Tankers--Automatic Pilot Systems in 
Waters Subject to 33 CFR parts 166 and 167 (USCG-2015-0926, RIN 
1625-AC27). It also was used in the proposed rule for Revision of 
Crane Regulation Standards for Mobile Offshore Drilling Units, 
Offshore Supply Vessels, and Floating Outer Continental Shelf 
Facilities (RIN 1625-AB78, USCG-2011-0992) as found on https://www.federalregister.gov/documents/2013/05/13/2013-11132/revision-of-crane-regulation-standards-for-mobile-offshore-drilling-units-modus-offshore-supply. See Federal Register, May 13, 2013 (78 FR 27913). 
No public comments were received on this estimate.
    \31\ Data of Commandant Instruction U comports with data on pay 
tables after application of load factor. Based on Coast Guard 
research the load factor for military positions is approximately 
1.85. This estimate was vetted in previous Coast Guard rulemakings 
as noted. Please see https://www.dfas.mil/militarymembers/payentitlements/Pay-Tables.html. See the hyperlink at the top of the 
page. The table provides monthly income which may be converted to 
hourly rates by dividing by 176 (22 days per month times 8 hours 
daily) then multiply by the military load factor.
---------------------------------------------------------------------------

    The Coast Guard estimates there are no costs associated with this 
proposed rule. The proposed rule does not require actions of 
manufacturers or vessel owners and operators. The proposal is not 
retroactive, and existing vessels are not required to be retrofitted.
    This proposed rule would not require owners and operators to 
acquire any standards incorporated by reference; they would not need 
the standard in hand to be in compliance. Owners and operators only 
would need to look for evidence from manufacturers that vessels meet or 
exceed the standard before purchase; such evidence could be found in a 
contract for purchase or repair of a vessel or in product documentation 
such as a user guide or warranty information. For these reasons, the 
Coast Guard has not included a cost for the procurement of the newer 
standards for vessel owners.
    The Coast Guard estimates that the regulated public (manufacturers) 
are currently in voluntary compliance with the requirements proposed by 
the rule based on manufacturer participation in the development of 
industry standards. When industry standards are promulgated, they 
undergo a process of review and comment by the industry. Input from 
manufacturers is key to developing new standards that consider the 
engineering capabilities of manufacturers. After the review and comment 
process, the newer standard is voted upon at the various governing 
bodies' committee meetings, and manufacturers are among those voting. 
For this reason, the Coast Guard

[[Page 57921]]

believes manufacturers are aware and knowledgeable about the newer 
standards. Given this, we further assume they already would own copies 
of the standards. For this reason, the Coast Guard has not computed a 
cost for them to procure the standards incorporated by reference. The 
Coast Guard requests public comment on our assumption of voluntary 
compliance with the proposed rule.
    Manufacturers already have been producing equipment to meet the 
standard and typically will begin to make manufacturing modifications 
even before such changes are adopted formally. Therefore, the Coast 
Guard does not anticipate that there would be costs to retrofit 
manufacturing equipment to be in compliance with the proposed rule. For 
previous similar rulemakings, no manufacturer commented that it would 
experience incremental costs of production to comply with newer 
editions of standards incorporated by reference.\32\ For these reasons, 
the Coast Guard has not included a cost for these provisions. However, 
the Coast Guard acknowledges that there is a non-zero probability that 
some manufacturer may need to purchase a newer standard. The estimated 
incremental cost to do so varies according to which standard is 
needed.\33\
---------------------------------------------------------------------------

    \32\ A similar rulemaking is the proposed rule Revision of Crane 
Regulation Standards for Mobile Offshore Drilling Units, Offshore 
Supply Vessels, and Floating Outer Continental Shelf Facilities 
(Docket Number: USCG-2011-0992). Please see https://www.federalregister.gov/documents/2013/05/13/2013-11132/revision-of-crane-regulation-standards-for-mobile-offshore-drilling-units-modus-offshore-supply (78 FR 27913).
    \33\ The cost to acquire an IBR standard would be estimated by 
the equation (0.25 hour x supv wage rate + 0.5 hour x admin 
assistant wage rate + cost of IBR + shipping cost). This is based on 
the publicly vetted cost estimation found in the regulatory analysis 
for the proposed rule Revision of Crane Regulation Standards for 
Mobile Offshore Drilling Units, Offshore Supply Vessels, and 
Floating Outer Continental Shelf Facilities (Docket Number: USCG-
2011-0992).
---------------------------------------------------------------------------

Cost Savings to the Regulated Public
    The proposal would result in cost savings to the regulated public 
and the Coast Guard from a reduction in labor for processing 
equivalency tests and no longer requiring labor to have education on 
the older standards incorporated by reference. The Coast Guard expects 
this proposed rule would generate cost savings for owners and operators 
who no longer would need to request a waiver of subchapter F regulatory 
requirements, known as an equivalency test request, from the MSC.
    Generally, the reason an owner or operator makes an equivalency 
request is to seek a determination from the Coast Guard on whether an 
edition of an industry standard not codified in the CFR is sufficient 
for use. To draft an equivalency request, an owner or operator would 
have material prepared by its engineering staff or by a contracted 
engineering firm.\34\
---------------------------------------------------------------------------

    \34\ If the owner or operator does not have staff sufficiently 
skilled to prepare the material, he or she may contract the services 
of an engineering design firm for the labor of a marine engineer or 
naval architect. The Coast Guard did not attempt to estimate the 
additional labor needed to engage contracted labor since it is 
unknown how many or even if an owner or operator would need outside 
labor to perform this task. Public comment is solicited on this.
---------------------------------------------------------------------------

    Based on MSC and CG-5PS data, the Coast Guard receives 
approximately 200 equivalency requests annually. The Coast Guard 
estimates it takes a marine engineer or naval architect employed by a 
vessel owner approximately 40 hours of time to develop an equivalency 
request and submit it to the Coast Guard for review. An estimated 0.5 
hour would be used by a supervisor engineer to approve the work. The 
request for an equivalency test is sent via email to the MSC. Given 
that the submittal is via email, the Coast Guard has not estimated 
postage costs.
    In addition, the regulated public would realize cost savings from 
the avoided cost of education for maintaining situational awareness on 
the existing standards incorporated by reference which the proposal 
would eliminate. The Coast Guard estimates that 0.5 hour is spent 
annually by engineers on education necessary to familiarize or re-
familiarize themselves with these standards. The Coast Guard believes 
that, as industry standards evolve and advance, older editions may not 
be readily accessible, even if they are incorporated by reference into 
the CFR. As such, we expect that engineers will find the older 
standards and read them on occasion to maintain an awareness of how 
these standards are different from current industry standards.
    In 2020, the Small Business Administration (SBA) published a rule 
where it determined that roughly 2,500 small disadvantaged businesses 
would save 0.5 hours each by no longer having to read 16 outdated 
regulations that SBA was removing through the rulemaking project.\35\ 
Given that this proposed rule relates to a similar subject matter--time 
saved from the removal of outdated or redundant regulations--the Coast 
Guard assumes a similar duration would be saved by industry employees. 
This 0.5 hour is a savings to vessel owners and operators and to 
manufacturers.
---------------------------------------------------------------------------

Small Disadvantaged Businesses, (Document Number: SBA 2020-08619) 
which was published on May 8, 2020. See https://www.federalregister.gov/documents/2020/05/08/2020-08619/regulatory-reform-initiative-small-disadvantaged-businesses (85 FR 27290).

Cost Savings to the Coast Guard
    The Coast Guard also would experience cost savings as a result of 
the proposed rule. When the Coast Guard receives an equivalency request 
from a vessel owner or operator, a Coast Guard engineering staff member 
at the MSC must review the request to provide a determination on 
whether the proposed standard(s) is equivalent to the existing 
standard(s) found in subchapter F. The Coast Guard MSC engineer needs 
approximately 32 hours to review an equivalency request, followed by 
0.5 hours of supervisor review. In a small percentage of more complex 
cases, the MSC works with CG-5PS engineering staff to complete the 
equivalency review. Following review, MSC emails a decision back to the 
owner or operator. The Coast Guard estimates it reviews 200 equivalency 
requests annually. To calculate the costs avoided by Coast Guard no 
longer processing equivalency requests, we multiplied the number of 
annual equivalency requests by the sum of the duration of initial 
review, review, and supervisor review multiplied by the loaded wage 
rates of the respective Coast Guard personnel performing the review 
(200 equivalency requests x (1 hour x average wage rate for uniformed 
engineer + 32 hours x wage rate for civilian engineer + 0.5 hours x 
wage rate for civilian engineering supervisor)).
    In addition, the Coast Guard would save labor costs annually, since 
staff would no longer need to maintain an awareness of the older 
versions of standards that are incorporated by reference. The proposal 
eliminates and replaces them with newer standards. The Coast Guard 
estimates that 0.5 hour annually is spent on education on the older 
standards by an employee tasked with working on equivalency requests. 
In the aforementioned SBA proposed rule, the agency claimed that about 
760 Federal contracting officers per year would save 0.5 hours from no 
longer reading outdated standards that were being removed by the rule. 
We therefore estimate 0.5 hours of education is similarly needed for 
Coast Guard personnel to maintain awareness and knowledge of older 
standards. This applies to six civilian engineers and six uniformed 
engineers who work on equivalency requests. To calculate the costs 
avoided by Coast Guard personnel no longer requiring education on 
outdated standards, we multiply 0.5 hours by the hourly wage rates of 
the

[[Page 57922]]

Coast Guard personnel (0.5 hours (6 uniformed engineers x average wage 
rate for uniformed engineer + 6 civilian engineers x wage rate for 
civilian engineer)).
    Table 7 presents the estimated cost savings of the proposed rule to 
the regulated public and to the Coast Guard.

    \36\ Existing regulations have been misunderstood as to whether 
a pressure vessel (PV) requires or does not require plan review by 
the Coast Guard. This proposed change clarifies regulatory intent 
and would preclude inquiries to the Coast Guard.
    \37\ The requirement for Coast Guard numbering of PVs is 
misunderstood often. The proposed change clarifies that Coast Guard 
numbering is required only when the Coast Guard has inspected the PV 
during construction (shop inspection).
    \38\ The requirement for use of the Coast Guard Symbol on PVs 
(Sec.  54.10-3) often is misunderstood. This section has been edited 
to assist readers in finding rules requiring stamping of the Coast 
guard Symbol.
    \39\ This section has been clarified by adding a section clearly 
identifying which PVs do not require stamping.
    \40\ The proposed change would give operators the option of 
undergoing an internal inspection every 10 years as opposed to 
requiring a hydrostatic test every 10 years.

Note: Totals may not sum due to independent rounding.

    The Coast Guard estimates an annualized cost savings to industry of 
$0.622 million (with a 7-percent discount rate) and an annualized cost 
savings to Government of $0.772 million (with a 7-percent discount 
rate) for a total annualized cost savings of $1.393 million in 2020 
dollars.
Cost Savings
    The proposed rule amends existing regulations in 46 CFR subchapter 
F. The proposed amendments would eliminate confusion caused by outdated 
and conflicting rules on marine engineering safety of various vessel 
components and systems and give the maritime industry clear 
instructions on how to comply with regulations. Moreover, this proposed 
rule would amend existing regulations to reflect current national and 
international standards. The proposed rule also would result in cost 
savings to the regulated public and the Federal Government, as noted 
further.
    Several of the proposed rule's changes have no cost effects (please 
see Table 4). These editorial changes, such as the removal of outdated 
terminology and the consolidation of text, would not result in cost 
savings but would clarify regulations, as noted earlier. Also, by 
incorporating the newer standards, the proposed changes would provide 
clarity and specificity. For these changes, the Coast Guard expects 
them to have no direct cost savings because they are unseverable from 
the cost savings noted previously.
    The compliance alternatives would remove overly prescriptive 
requirements, simplify regulatory compliance, and provide regulatory 
flexibility for industry. The proposal would add a compliance 
alternative to hydrostatic tests, thereby allowing the regulated public 
to perform an internal inspection in lieu of the hydrostatic test. The 
proposed inclusion of this compliance alternative would save a given 
vessel owner labor and material. In order to comply with the existing 
requirement for hydrostatic tests, the vessel owner must remove 
existing lagging around the unit, then replace it once the test is 
completed. The proposed compliance alternative would involve less labor 
and would not necessitate the removal and replacement of lagging as the 
existing requirements do. The Coast Guard has not estimated a cost for 
this alternative, because it is unknown how many vessel owners would 
choose to pursue the alternative. Because equipment sizes vary, the 
amount of labor and material needed to comply now and under the 
alternative is also unknown.\41\ The Coast Guard invites public comment 
on this issue.
---------------------------------------------------------------------------

    \41\ This information would be needed to ascertain the existing 
cost of compliance; the Coast Guard could then estimate the cost 
savings of the proposed new compliance alternative.
---------------------------------------------------------------------------

Alternatives Considered
    Within the Coast Guard's development of this proposed rule, 
significant alternatives to the regulatory component(s) were considered 
to determine if any alternative could accomplish the stated objectives 
of applicable statutes and could minimize any significant economic 
impact of the rule on small entities beyond the proposed rule. Among 
these alternatives were the following:
Alternative 1: Take No Action
    The Coast Guard could have chosen not to pursue the rulemaking. 
Taking no action would cause no incremental costs to regulated entities 
nor to the Coast Guard. However, in doing nothing, the Coast Guard 
would have no mechanism to update regulations to reflect current 
practices and improve their relevance to the public. There would be 
neither an increase nor decrease in benefits to regulated entities due 
to the alternative. The proposed rule has been estimated to produce 
quantifiable cost savings to the Coast Guard and the regulated public, 
which would not be possible under the alternative of no action.
    The standards currently incorporated by reference are outdated. To 
keep them codified would, in theory, maintain existing safety levels. 
However, because they are so outdated, they are sparsely available. 
Compliance with them may become problematic in the future due to lack 
of availability. The older editions of the standards do not contain 
guidance for several current industry practices. Maintaining the 
regulations with the existing standards incorporated by reference would 
not allow for cost savings as the proposal would do.
    The goal of this proposed rule is to streamline requirements, to 
clarify existing rules and to increase enforcement effectiveness. The 
no-action alternative would result in no additional costs and maintain 
current levels of public safety. Similarly, the proposed rule is 
anticipated to have cost savings opportunities; \42\ and these savings 
would not accrue to the public if current regulations were not amended. 
The proposed rule also is being promulgated to provide clarity on 
regulatory intentions; a no-action choice would not permit this 
clarification to be given to the public. This alternative would result 
in no benefits as there would be no changes to current practice; 
therefore, the Coast Guard rejected this alternative.
---------------------------------------------------------------------------

    \42\ The proposed adoption of the newer editions would mean that 
some outdated requirements of the earlier editions are no longer 
required or are converted to recommendations rather than 
requirements. The newer editions also include some flexibility in 
requirements and recommendations based on the given circumstances. 
The reader may consult the appendix for a detailed analysis of the 
changes between the editions.

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

[[Page 57924]]

Alternative 2: Delay the Effective Date
    The Coast Guard could have delayed the effective date. Delayed 
effective dates are used to aid in compliance implementation, 
particularly when the labor costs or capital costs are considerable. 
The compliance costs for the proposal are zero as noted earlier, and a 
delayed effective date would delay the cost savings opportunities to 
all parties. For these reasons, the Coast Guard rejected this 
alternative.
Alternative 3. Exempt Small Entities
    The Coast Guard could have exempted small entities from some or all 
of the proposed rule's provisions. In principle, an exemption would 
save small entities time and money to comply with regulations. 
Exemptions for small entities often are used when costs of compliance, 
such as capital costs, are high. However, there are no costs of 
compliance for this proposed rule. For this alternative, an exemption 
may cause the cost savings opportunities of the rulemaking to be 
precluded for small entities and, thereby, the total value of the 
rule's cost savings would decline accordingly.
    The proposal would implement requirements for business practices in 
which the majority (if not all) of small businesses now engage. An 
exemption for small business entities from the rulemaking would have 
little effective and practical impact on small business entities. There 
is a high level of voluntary compliance and limited applicability for 
the affected population. The costs of compliance are zero and the rule 
is applicable only if an actionable event occurs (for example, if a new 
vessel is procured or an existing vessel undergoes a major conversion). 
For these reasons, the Coast Guard did not pursue an exemption for 
small entities.

B. Small Entities

    The Regulatory Flexibility Act of 1980 (RFA), 5 U.S.C. 601-612, and 
Executive Order 13272 (Consideration of Small Entities in Agency 
Rulemaking) requires a review of proposed and final rules to assess 
their impacts on small entities. An agency must prepare an initial 
regulatory flexibility analysis unless it determines and certifies that 
a rule, if promulgated, would not have a significant impact on a 
substantial number of small entities.
    Under the RFA, we have considered whether this proposed rule would 
have a significant economic impact on a substantial number of small 
entities. The term ``small entities'' \43\ comprises small businesses, 
not-for-profit organizations that are independently owned and operated 
and are not dominant in their fields, and governmental jurisdictions 
with populations of less than 50,000.
---------------------------------------------------------------------------

    \43\ The Regulatory Flexibility Act considers the term ``small 
entity'' as having the same meaning as the terms ``small business,'' 
``small organization'' and ``small governmental jurisdiction.''
---------------------------------------------------------------------------

    Based on our analysis, this proposed rule would affect vessel 
owners and operators, manufacturers and class societies. While the 
proposed rule excludes public vessels,\44\ there exists considerable 
diversity in the types of vessel owners that may be impacted by the 
proposal. Some vessel owners potentially impacted by this proposed rule 
include Tribal, State, and local governments as well as nonprofits 
including colleges and universities, museums, and science foundations.
---------------------------------------------------------------------------

    \44\ 42 U.S. Code 6939d(c)(1) provides, ``The term `public 
vessel' means a vessel owned or bareboat chartered and operated by 
the United States or by a foreign nation, except when the vessel is 
engaged in commerce.''
---------------------------------------------------------------------------

    The MISLE database maintained by the Coast Guard contains detailed 
information on the U.S. maritime industry, including vessel and major 
equipment specific information, and MISLE data suggest that the 
potentially affected population contains thousands of vessels for 
thousands of vessel owners and operators. While there exists no exact 
figure of the population of U.S.-flagged vessels and their owners and 
operators, and the Coast Guard does not maintain a registry of all 
vessels, many vessels are documented and therefore there is a record of 
the owner. For these reasons, the Coast Guard was able to estimate the 
number of vessel owners and operators impacted by the proposed 
rulemaking based on the MISLE dataset of U.S.-flagged vessels. The 
Coast Guard used this dataset of vessels, refined to eliminate 
duplicate managing owner names, to create a dataset of unique owner 
names to serve as a proxy for the number of vessel owners in the 
affected population.
    The SBA uses either revenue level or employment size to establish 
small entity size categories.\45\ For that reason, the Coast Guard 
reviewed publicly available information to determine revenue and 
employment estimates. These sources included but were not limited to 
www.manta.com, www.dnb.com, and the corporate websites of several 
businesses. The reader should note that the Coast Guard used data for 
the governing body of a corporate entity. In other words, for affected 
business entities that were subsidiaries of another company; the 
employment size and revenue level of the parent company was compared to 
the small business size standard for the North American Industry 
Classification System (NAICS) code of the parent company.\46\
---------------------------------------------------------------------------

    \45\ The SBA threshold for a small entity is either the maximum 
number of employees or the maximum revenue level (or population size 
for a State/local government). Size standards may be found in 13 CFR 
121.201.
    \46\ The NAICS codes for the parent company may differ for its 
subsidiaries.
---------------------------------------------------------------------------

    The Coast Guard used a random sample to estimate the number of 
small entities that are manufacturers and managing owners.\47\ The 
Coast Guard was able to find data on approximately 92 percent of the 
sampled managing owner businesses and 88.6 percent of manufacturers 
impacted by the rule. 48 49 Publicly available data were 
used to obtain company-specific information such as annual revenues and 
number of employees.\50\ Any company for which the Coast Guard did not 
find data was considered small.\51\ Using the SBA's ``Table of Size 
Standards'' and the NAICS codes listed in the table, the Coast Guard 
found that 21.35 percent of governmental entities that were managing 
owners of vessels are small entities.\52\ For nonprofits, 84.48 percent 
were small entities.\53\ For the remaining companies owning vessels in 
the affected population, the Coast Guard found that 85.85 percent were 
small entities. For manufacturers, the Coast Guard estimates that 62.03 
percent of companies were small entities.
---------------------------------------------------------------------------

    \47\ Separate samples were performed for managing owners that 
are governmental entities or nonprofits.
    \48\ The Coast Guard used a sample size of 190 (alpha = 0.10, 
confidence interval of 90%).
    \49\ We found data on 81 percent of nonprofits that were 
managing owners and data for all governmental entities that were 
managing owners.
    \50\ www.dnb.com and www.charitynavigator.org (for nonprofits).
    \51\ https://www.sba.gov/document/support--table-size-standards.
    \52\ The following NAICS codes were found for most sampled 
owners (excluding governmental entities and nonprofits): 441222 Boat 
Dealers; 237990 Other Heavy and Civil Engineering Construction; 
325110 Petrochemical Manufacturing; 336611 Ship Building and 
Repairing; 483111 Deep Sea Freight Transportation, 454310 Fuel 
Dealers, 237310 Hwy, Street, and Bridge Construction; 483211 Inland 
Water Freight Transportation; and 488330 Navigational Services to 
Shipping. This list is not exclusive.
    \53\ The most commonly found NAICS codes for nonprofits in the 
sample were 813410 Civic and Social Organizations; 611710 
Educational Support Services; 813312 Environment, Conservation and 
Wildlife Organizations; and 712110 Museums. This list is not 
exclusive.
---------------------------------------------------------------------------

    Cost savings are incurred only under conditions as specified in the 
proposal. The cost saving for each vessel owner or operator would be 
approximately $2,923 per entity, which is less than 1 percent

[[Page 57925]]

of revenue for 72.48 percent of small entity managing owners. These 
cost savings are incurred only if the regulated entity experienced 
tasks as noted in the proposed rule. For most vessel owners and 
operators, there would be no cost nor cost savings from the proposed 
rule.
    Therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that 
this proposed rule would not have a significant economic impact on a 
substantial number of small entities.
    If you think that your business, organization, or governmental 
jurisdiction qualifies as a small entity and that this rule would have 
a significant economic impact on it, please submit a comment to docket 
at the address in the ADDRESSES section. In your comment, explain why 
you think it qualifies and how and to what degree this rule would 
affect it economically.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement 
Fairness Act of 1996, Public Law 104-121, we want to assist small 
entities in understanding this proposed rule so that they can better 
evaluate its effects on them and participate in the rulemaking. If the 
proposed rule would affect your small business, organization, or 
governmental jurisdiction and you have questions concerning its 
provisions or options for compliance, please call or email the person 
in the FOR FURTHER INFORMATION CONTACT section of this proposed rule. 
The Coast Guard will not retaliate against small entities that question 
or complain about this proposed rule or any policy or action of the 
Coast Guard.
    Small businesses may send comments on the actions of Federal 
employees who enforce, or otherwise determine compliance with, Federal 
regulations to the Small Business and Agriculture Regulatory 
Enforcement Ombudsman and the Regional Small Business Regulatory 
Fairness Boards. The Ombudsman evaluates these actions annually and 
rates each agency's responsiveness to small business. If you wish to 
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR 
(1-888-734-3247).

D. Collection of Information

    This proposed rule would not require a modification of an existing 
collection of information (Plan Approval and Records for Marine 
Engineering Systems--Title 46 CFR Subchapter F OMB Control Number: 
1625-0097) and would not call for new collection of information under 
the Paperwork Reduction Act of 1995 (PRA), 44 U.S.C. 3501-3520. As 
defined in 5 CFR 1320.3(c), ``collection of information'' comprises 
reporting, recordkeeping, monitoring, posting, labeling, and other 
similar actions.

E. Federalism

    A rule has implications for federalism under Executive Order 13132 
(Federalism) if it has a substantial direct effect on the States, on 
the relationship between the national government and the States, or on 
the distribution of power and responsibilities among the various levels 
of government. We have analyzed this proposed rule under Executive 
Order 13132 and determined that it is consistent with the fundamental 
federalism principles and preemption requirements described in 
Executive Order 13132. Our analysis follows.
    It is well settled that States may not regulate in categories 
reserved by Congress for regulation by the Coast Guard. It is also well 
settled that all of the categories regulated under 46 U.S.C. 3306 and 
3703, as well as any other category in which Congress intended the 
Coast Guard to be the sole source of a vessel's obligations, are within 
the field foreclosed from regulation by the States. See the Supreme 
Court's decision in United States v. Locke and Intertanko v. Locke, 529 
U.S. 89, 120 S.Ct. 1135 (2000). This proposed rulemaking updates the 
references to incorporated standards in 46 CFR Subchapter F, which is 
authorized under 43 U.S.C. 1333, 46 U.S.C. 3306, and 46 U.S.C. 3703. 
Therefore, because the States may not regulate within these categories, 
this rule is consistent with the fundamental federalism principles and 
preemption requirements described in Executive Order 13132.
    While it is well settled that States may not regulate in categories 
in which Congress intended the Coast Guard to be the sole source of a 
vessel's obligations, the Coast Guard recognizes the key role that 
State and local governments may have in making regulatory 
determinations. Additionally, for rules with federalism implications 
and preemptive effect, Executive Order 13132 specifically directs 
agencies to consult with State and local governments during the 
rulemaking process. If you believe this proposed rule has implications 
for federalism under Executive Order 13132, please contact the person 
listed in the FOR FURTHER INFORMATION section of this preamble.

F. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995, 2 U.S.C. 1531-1538, 
requires Federal agencies to assess the effects of their discretionary 
regulatory actions. In particular, the Act addresses actions that may 
result in the expenditure by a State, local, or tribal government, in 
the aggregate, or by the private sector of $100,000,000 (adjusted for 
inflation) or more in any one year. Although this proposed rule would 
not result in such an expenditure, we do discuss the effects of this 
proposed rule elsewhere in this preamble.

G. Taking of Private Property

    This proposed rule would not cause a taking of private property or 
otherwise have taking implications under Executive Order 12630 
(Governmental Actions and Interference with Constitutionally Protected 
Property Rights).

H. Civil Justice Reform

    This proposed rule meets applicable standards in sections 3(a) and 
3(b) (2) of Executive Order 12988, (Civil Justice Reform), to minimize 
litigation, eliminate ambiguity, and reduce burden.

I. Protection of Children

    We have analyzed this proposed rule under Executive Order 13045 
(Protection of Children from Environmental Health Risks and Safety 
Risks). This proposed rule is not an economically significant rule and 
would not create an environmental risk to health or risk to safety that 
might disproportionately affect children.

J. Indian Tribal Governments

    This proposed rule does not have Tribal implications under 
Executive Order 13175 (Consultation and Coordination with Indian Tribal 
Governments), because it would not have a substantial direct effect on 
one or more Tribal governments, on the relationship between the Federal 
Government and Tribal governments, or on the distribution of power and 
responsibilities between the Federal Government and Tribal governments.

K. Energy Effects

    We have analyzed this proposed rule under Executive Order 13211 
(Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use). We have determined that it is not a 
``significant energy action'' under that order because it is not a 
``significant regulatory action'' under Executive Order 12866 and is 
not likely to have a significant adverse effect on the supply, 
distribution, or use of energy.

[[Page 57926]]

L. Technical Standards

    The National Technology Transfer and Advancement Act, codified as a 
note to 15 U.S.C. 272, directs agencies to use voluntary consensus 
standards in their regulatory activities unless the agency provides 
Congress, through OMB, with an explanation of why using these standards 
would be inconsistent with applicable law or otherwise impractical. 
Voluntary consensus standards are technical standards (such as for 
specifications of materials, performance, design, or operation; test 
methods; sampling procedures; and related management systems practices) 
that are developed or adopted by voluntary consensus standards bodies.
    This proposed rule uses the following voluntary standards:

M. Environment

    We have analyzed this proposed rule under Department of Homeland 
Security Management Directive 023-01, Rev. 1, associated implementing 
instructions, and Environmental Planning COMDTINST 5090.1 (series), 
which guide the Coast Guard in complying with the National 
Environmental Policy Act of 1969 (42 U.S.C. 4321-4370f), and have made 
a preliminary determination that this action is one of a category of 
actions that do not individually or cumulatively have a significant 
effect on the human environment. A preliminary Record of Environmental 
Consideration supporting this determination is available in the docket. 
For instructions on locating the docket, see the ADDRESSES section of 
this preamble. This proposed rule would be categorically excluded under 
paragraphs L54, L57 and L58 of Appendix A, Table 1 of DHS Instruction 
Manual 023-01, Rev. 1.\54\ Paragraph L54 pertains to regulations which 
are editorial and procedural; paragraph L57 pertains to regulations 
concerning manning, documentation, admeasurement, inspection, and 
equipping of vessels; and paragraph L58 pertains to regulations 
concerning equipment approval and carriage requirements.

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

    This proposed action involves amending rules relating to standards 
for marine engineering details for various types of vessels, including 
incorporation of national and international safety standards by 
reference. This proposed rule is part of the Coast Guard's ongoing 
regulatory reform efforts to increase compliance options for the 
regulated public while providing cost savings to the public and U.S. 
Government, and also would promote the Coast Guard's marine safety 
mission. We seek any comments or information that may lead to the 
discovery of a significant environmental impact from this proposed 
rule.

    For primary definitions associated with power boiler design, see 
Section I of the ASME BPVC (incorporated by reference; see Sec.  52.01-
1).
    (a) Types of boilers--(1) Main power boiler. A main power boiler is 
a steam boiler used for generating steam for main propulsion.
    (2) Auxiliary or donkey boiler. An auxiliary or donkey boiler is a 
steam boiler used for general purposes other than main propulsion.
    (3) Watertube boiler. A watertube boiler is a steam boiler in which 
the boiler tubes contain water and steam. The heat is applied to the 
outside surface of the tubes.

[[Page 57931]]

    (4) Internally fired firetube boiler (scotch boiler). An internally 
fired firetube boiler is a steam boiler containing furnaces, one or 
more combustion chambers and tubes or flues, which are surrounded by 
water and through which the products of combustion pass from the 
furnace to the uptake.
    (5) Externally fired firetube or flue boiler (horizontal return 
tubular). An externally fired firetube or flue boiler is a steam 
boiler, part of the outer shell of which is exposed to fire or to the 
products of combustion, and containing flues through which such 
products pass from the furnace to the uptake.
    (6) Unfired steam boiler. A pressure vessel in which steam is 
generated by means other than fuel combustion is classed as an unfired 
steam boiler. (See Sec.  54.01-10 of this subchapter.)
    (b) Parts of boilers-- (1) Superheater. A superheater is an 
appliance, normally consisting of tube rows, for the purpose of 
increasing the temperature of steam above the saturation temperature.
    (2) Economizer. An economizer is a feed-water heater usually 
located in the uptake or casing of a boiler to absorb heat from the 
waste gases.
    (3) Furnace. A furnace is a firebox or a large flue in which the 
fuel is burned.
    (4) Flues. Flues are cylindrical shells made of seamless or welded 
tubing, or with a riveted longitudinal joint, the ends being attached 
by riveting or welding. Their purpose is to provide additional heating 
surface and to form a path for the products of combustion.

diameter constituting the main part of the heating surface of a boiler 
or superheater.
    (c) Pressure relief devices. For boilers, pressure vessels, and 
pressure piping, a pressure relief device is designed to open to 
prevent a rise of internal pressure in excess of a specified value due 
to emergency or abnormal conditions. It may be a pressure relief valve 
or a nonreclosing pressure relief device.
    (1) Pressure relief valve. A pressure relief valve is a pressure 
relief device which is designed to reclose and prevent the further flow 
of fluid after normal conditions have been restored.
    (i) Safety valve. A safety valve is a pressure relief valve 
actuated by inlet static pressure and characterized by rapid opening or 
pop action. Examples of types used on boilers include:
    (A) Spring-loaded safety valve. A spring-loaded safety valve is a 
safety valve fitted with a spring which normally holds the valve disk 
in a closed position against the seat and allows it to open or close at 
predetermined pressures. Spring-loaded safety valves are characterized 
by pop action.
    (ii) Pilot operated pressure relief valve. A pilot operated 
pressure relief valve is a pressure relief valve in which the major 
relieving device is combined with and is controlled by a self-actuated 
auxiliary pressure relief pilot valve.
    (iii) Temperature actuated pressure relief valve. A temperature 
actuated pressure relief valve is a dual-function relief device 
designed to protect against both excessive pressure and temperature.
    (2) Nonreclosing pressure relief device. A nonreclosing pressure 
relief device is a pressure relief device not designed to reclose after 
operation.
    (i) Rupture disk device. A rupture disk device is a device actuated 
by inlet static pressure and designed to function by the bursting of a 
pressure retaining disk.
    (ii) Explosion rupture disk device. An explosion rupture disk 
device is a rupture disk device designed for use at high rates of 
pressure rise.
    (iii) Fusible plug device. A fusible plug device is a device 
designed to function by the yielding or melting of a plug of suitable 
melting temperature.
    (3) Vacuum relief valve. A vacuum relief valve is a valve designed 
to admit fluid or gas to prevent an excessive internal vacuum.
    (d) Other boiler attachments--(1) Mountings. Mountings are nozzle 
connections, distance pieces, valves, or fittings attached directly to 
the boiler.
    (2) Main steam stop valve. A main steam stop valve is a valve 
usually connected directly to the boiler for the purpose of shutting 
off the steam to/from the main steam line.
    (3) Auxiliary steam stop valve. An auxiliary steam stop valve is a 
valve usually connected directly to the boiler for the purpose of 
shutting off the steam to/from the auxiliary lines.
    (4) Manifold. A manifold is a fitting with two or more branches 
having valves either attached by bolting or integral with the fitting.
    (5) Blowoff valve. A blowoff valve is a valve connected directly to 
the boiler for the purpose of blowing out water, scum or sediment.
    (6) Dry pipe. A dry pipe is a perforated or slotted pipe placed in 
the highest part of the steam space of a boiler to prevent priming 
(water carryover).
    (7) Water column. A water column is a fitting or tube equipped with 
a water glass attached to a boiler for the purpose of indicating the 
water level.
    (8) Test cocks. Test cocks are small valves on a boiler for 
indicating the water level or water sampling.
    (9) Fusible plugs. Fusible plugs are plugs made with a bronze 
casing and a tin filling which melts at a temperature of 445[deg] to 
450 [deg]F. They are intended to melt in the event of low water level.
    (e) Boiler fabrication--(1) Repair. Repair is the restoration of 
any damaged or impaired part to an effective and safe condition.
    (2) Alteration. Alteration is a structural modification to or 
departure from an approved design or existing construction.
    (3) Access or inspection openings. Access or inspection openings 
are holes cut in the shells or heads of boilers or boiler pressure 
parts for the purpose of inspection and cleaning.
    (f) Gage (or gauge) pressure. Gage pressure is the difference 
between the pressure at the point being measured and the ambient 
pressure for the gage. It is measured in units such as pounds per 
square inch gage (p.s.i.g.).
    (g) Maximum allowable working pressure. For a definition of maximum 
allowable working pressure, see PG-21 of Section I of the ASME BPVC.

Sec.  52.01-120  Safety valve and safety relief valves (modifies PG-67 
through PG-73).

    (a) * * *
    (4) (Modifies PG-70.) The total rated relieving capacity of drum 
and superheater safety valves as certified by the valve manufacturer 
must not be less than the maximum generating capacity of the boiler 
which must be determined and certified by the boiler manufacturer. This 
capacity shall be in compliance with PG-70 of Section I of the ASME 
BPVC.
    (5) In the event the maximum steam generating capacity of the 
boiler is increased by any means, the relieving capacity of the safety 
valves must be checked by an inspector, and, if necessary, valves of 
increased relieving capacity must be installed.
    (6) (Modifies PG-67.) Drum safety valves must be set to relieve at 
a pressure not in excess of that allowed by the Certificate of 
Inspection. Where for any reason this is lower than the pressure for 
which the boiler was originally designed and the revised safety valve 
capacity cannot be recomputed and certified by the valve manufacturer, 
one of the tests described in PG-69 of section I of the ASME BPVC must 
be conducted in the presence of the Inspector to insure that the 
relieving capacity is sufficient at the lower pressure.
* * * * *
    (8) Lever or weighted safety valves now installed may be continued 
in use and may be repaired, but when repairs are not possible, lever or 
weighted safety valves must be replaced by valves conforming to the 
requirements of this section.

    (b)(1) (Modifies PG-68.) Superheater safety valves must be as 
indicated in PG-68 of Section I of the ASME BPVC except as noted 
otherwise in this paragraph.
    (2) The setting of the superheater safety valve must not exceed the 
design pressure of the superheater outlet flange or the main steam 
piping beyond the superheater. To prevent damage to the superheater, 
the drum safety valve must be set at a pressure not less than that of 
the superheater safety valve setting plus 5 pounds, plus the pressure 
drop through the superheater and associated piping, including the 
desuperheater if fitted. See also Sec.  52.01-95(b)(1).
* * * * *
    (c)(1) (Modifies PG-71.) Safety valves must be installed as 
indicated in PG-71 of Section I of the ASME BPVC except as noted 
otherwise in this paragraph (c).
    (2) The final setting of boiler safety valves must be checked and 
adjusted under steam pressure and, if possible, while the boiler is on 
line and at operating temperatures, to the satisfaction of a marine 
inspector who, upon acceptance, must seal the valves. This regulation 
applies to both drum and superheater safety valves of all boilers.
    (3) The safety valve body drains required by PG-71 of Section I of 
the ASME BPVC must be run as directly as possible from the body of each 
safety valve, or the drain from each safety valve may be led to an 
independent header common only to boiler safety valve drains. No valves 
of any type may be installed in the leakoff from drains or drain 
headers and they must be led to suitable locations to avoid hazard to 
personnel.
    (d)(1) (Modifies PG-72.) The operation of safety valves must be as 
indicated in PG-72 of Section I of the ASME BPVC except as noted in 
paragraph (d)(2) of this section.
    (2) (Modifies PG-73.) The lifting device required by PG-73.1.3 of 
Section I of the ASME BPVC must be fitted with suitable relieving gear 
so arranged that the controls may be operated from the fireroom or 
engineroom floor.

    (a) Charpy V-notch impact tests. Where required, Charpy V-notch 
tests must be conducted in accordance with ASTM E23 (incorporated by 
reference, see Sec.  54.01-1), using the Type A specimen shown in ASTM 
E23--Figure 4. Special attention is drawn to the fact that the Charpy 
Keyhole and U-notch specimens are not acceptable substitutes for the 
Charpy V-notch specimen and must not be used to qualify materials 
within the scope of this subpart. Each set of Charpy impact tests must 
consist of three specimens. For materials \1/2\-inch thick or less, the 
largest possible Charpy specimens for that thickness must be cut 
centered at the material's mid-thickness. For materials thicker than 
\1/2\-inch, full size Charpy specimens must be cut centered at a 
location as near as practicable to a point midway between the 
material's surface and half-thickness. Except where otherwise 
specified, transversely oriented specimens must be used. When 
longitudinal specimens are used, the required energy values may not be 
less than 1.5 times the values required for transversely oriented 
specimens. In all cases the notch must be cut normal to the material's 
surface. Test specimens must be taken at least one ``t'' from any heat 
treated edge (where ``t'' is the material's nominal thickness).
    (b) Drop weight tests. Where required, drop weight tests must be 
conducted for no-break performance in accordance with ASTM E208 
(incorporated by reference, see Sec.  54.01-1). For material 
thicknesses between \1/2\-inch and \5/8\-inch, the ASTM E208 specimen 
P-3, machined to \1/2\-inch thickness, must be used with a stop 
distance of 0.090-inch. In preparing weld specimens for dropweight 
testing, weld reinforcement must be ground flush, the hard facing bead 
centered on and transverse to the weld, and the notch centered on and 
parallel to the weld axis.

* * * * *
    (c) * * *

[[Page 57940]]

    (3) One set of Charpy impact specimens or two drop-weight 
specimens, as applicable, must be cut from each such test block and 
these specimens will represent all forgings (up to 5 short tons) that 
are from the same heat of material and given the same heat-treatment as 
the test block, and the thickness of which does not differ from that of 
the test block by more than plus or minus 50 percent of 1\1/2\ inches, 
whichever is less, except that forged flanges and tube sheets thicker 
than 5\1/2\ inches may be qualified from a 4-inch test block.
* * * * *
    (f) * * * For such parts too small to impact test, the Commandant 
will determine toughness qualifications based on material, chemical, 
and mechanical properties.

Sec.  54.10-10   Standard hydrostatic test (modifies UG-99).

* * * * *
    (b) The hydrostatic-test pressure must be at least one and three-
tenths (1.30) times the maximum allowable working pressure stamped on 
the pressure vessel, multiplied by the ratio of the stress value ``S'' 
at the test temperature to the stress value ``S'' at the design 
temperature for the materials of which the pressure vessel is 
constructed. The values for ``S'' must be taken from tables UCS 23, UNF 
23, UHA 23, or UHT 23 of Section VIII of the ASME BPVC (incorporated by 
reference, see Sec.  54.01-1). The value of ``S'' at test temperature 
must be that taken for the material of the tabulated value of 
temperature closest to the test temperature. The value of ``S'' at 
design temperature must be as interpolated from the appropriate table. 
No ratio less than one must be used. The stress resulting from the 
hydrostatic test must not exceed 90 percent of the yield stress of the 
material at the test temperature. External loadings which will exist in 
supporting structure during the hydrostatic test should be

[[Page 57941]]

considered. The design must consider the combined stress during 
hydrostatic testing due to pressure and the support reactions. This 
stress must not exceed 90 percent of the yield stress of the material 
at the test temperature. In addition the adequacy of the supporting 
structure during hydrostatic testing should be considered in the 
design.

Sec.  56.20-9  Valve construction.

    (a) Each valve must close with a right-hand (clockwise) motion of 
the handwheel or operating lever as seen by one facing the end of the 
valve stem. Each nonrising-stem valve, lever-operated valve, or other 
valve where, because of design, the position of the disc or closure 
mechanism is not obvious must be fitted with an indicator to show 
whether the valve is opened or closed. No such indicator is required 
for any valve located in a tank or similar inaccessible space when 
indicators are available at accessible sites. The operating levers of 
quarter-turn valves must be parallel to the fluid flow when open and 
perpendicular to the fluid flow when closed.
    (b) Valves of Class I piping systems having diameters exceeding 2 
inches must have bolted, pressure seal, or breech lock bonnets and 
flanged or welding ends. Socket type welding ends must meet Sec.  
56.30-5(c) and Sec.  56.30-10(b)(4). For diameters not exceeding 2 
inches, screwed union bonnet or bolted bonnet, or bonnetless valves 
which prevent the stem from screwing out of the body may be employed. 
Outside screw and yoke design must be used for valves 3 inches and 
larger for pressures above 600 psig. Cast iron valves with screwed-in 
or screwed-over bonnets are prohibited. Union bonnet type cast iron 
valves must have the bonnet ring made of steel, bronze, or malleable 
iron.
    (c) Valves must be designed for the maximum pressure to which they 
may be subjected, but in no case must the design pressure be less than 
50 psig. The use of wafer type resilient seated valves is subject to 
the requirements of Sec.  56.20-15.
    (d) Disks or disk faces, seats, stems and other wearing parts of 
valves must be made of material possessing corrosion and heat-resisting 
qualities suitable for the service conditions to which they may be 
subjected.
    (e) Plug cocks must be constructed with satisfactory and positive 
means of preventing the plug from becoming loosened or removed from the 
body when the plug is operated.
    (f) Cocks must be marked in a straight line with the body to 
indicate whether they are open or closed.
0
144. Revise Sec.  56.20-15 to read as follows:


Sec.  56.20-15  Valves employing resilient material.

    (a) A valve in which the closure is accomplished by resilient 
nonmetallic material instead of a metal to metal seat must comply with 
the design, material, construction and testing for valves specified in 
this section.
    (b) Valves employing resilient material are divided into three 
categories: Positive shutoff, Category A, and Category B, and must be 
tested and used as follows:
    (1) Positive shutoff valves. The closed valve must pass less than 
10 ml/hr (0.34 fluid oz/hr) of liquid, or less than 3 l/hr (0.11 cubic 
ft/hr) of gas per inch nominal pipe size through the line at full rated 
pressure after being subjected to the fire test requirements of API 607 
(incorporated by reference; see Sec.  56.01-2). Packing material must 
be fire resistant. Piping subject to internal head pressure from a tank 
containing oil must be fitted with positive shutoff valves located at 
the tank in accordance with Sec.  56.50-60(d). Positive shutoff valves 
may be used in any location in lieu of a Category A or Category B 
valve.
    (2) Category A valves. Category A valves may be used in any 
location except where positive shutoff valves are required by Sec.  
56.50-60(d). To be qualified as a Category A valve, the valve must meet 
the fire test and leakage requirements of API 607.
    (i) Category A valves are required at vital piping system 
manifolds;
    (ii) Category A valves must be used in isolation valves in cross-
connects between two piping systems, at least one of which is a vital 
system, where failure of the valve in a fire would prevent the vital 
system(s) from functioning as designed, and
    (iii) Category A valves must be used for valves providing closure 
for any opening in the shell of the vessel.
    (3) Category B valves. The closed valve will not provide effective 
closure of the line or will permit appreciable leakage from the valve 
after the resilient material is damaged or destroyed. Category B valves 
are not required to be

[[Page 57949]]

tested and may be used in any location except where a Category A or 
positive shutoff valve is required.
    (c) Resiliently seated valves previously accepted by the Commandant 
or the Marine Safety Center may continue to be used within the service 
restrictions of their acceptance.

Sec.  56.50-1  General (replaces 122).

    The requirements in this subpart for piping systems apply instead 
of those in Section 122 of ASME B31.1 (incorporated by reference; see 
Sec.  56.01-2). The following installation requirements are applicable 
to all systems:
    (a) Where pipes and scuppers are carried through watertight or 
oiltight bulkheads, decks or tank tops, or are carried through fire 
control bulkheads and decks, the integrity of the structure must be 
maintained. Lead or other heat sensitive materials must not be used in 
piping systems in bulkhead or deck penetrations where fire would impair 
the integrity of the penetration. (For nonmetallic or plastic pipe 
installations, see Sec.  56.60-25(a).) Openings in structure through 
which pipes pass must be reinforced where necessary. Metallic materials 
having a melting point of 1,700 [deg]F or less are considered heat 
sensitive and if used must be suitably insulated.
    (b)(1) Pipes piercing the collision bulkhead must be fitted with 
valves operable from above the bulkhead deck and the valve must be 
fitted inside the forepeak tank adjacent to the collision bulkhead. The 
pipe penetrating the collision bulkhead must be welded to the bulkhead 
on both sides. The valve body must be of steel or ductile cast iron.
    (2) Passenger vessels must not have the collision bulkhead pierced 
below the margin line by more than one pipe conveying liquids in the 
forepeak tank.
    (c) Valves and cocks not forming part of a piping system are not 
permitted in watertight subdivision bulkheads. However, sluice valves 
or gates in oiltight bulkheads of tankships may be used if approved by 
the Marine Safety Center.
    (d) Piping must generally not be run over switchboards, and must be 
installed as far away from other electrical equipment as practicable. 
When such leads are necessary, provision must be made to prevent 
leakage from damaging the equipment.
    (e) Stuffing boxes must not be used on deep tank bulkheads, double 
bottoms or in any position where they cannot be easily examined. This 
requirement does not apply to ore carriers operating on the Great Lakes 
or cargo lines of oil tankers.
    (f) Piping systems must be installed so that under no condition 
will the operation of safety or relief valves be impaired.
    (g)(1) Power actuated valves may be used if approved for the system 
by the Marine Safety Center. All power actuated valves must have a 
backup manual means of operation.
    (2)(i) Remote valve controls must be fitted with nameplates 
describing the applicable system.
    (ii) Remote valve controls must be accessible under normal service 
conditions.
    (iii) Remote valve controls, except reach rods, must be fitted with 
indicators that show whether the valves they control are open or 
closed. Valve position indicating systems must be independent of valve 
control systems.
    (iv) Valve reach rods must be adequately protected.
    (v) Solid reach rods must be used in tanks containing liquids, 
except that reach rods of constructed of extra-heavy pipe may be 
considered acceptable by the OCMI.
    (3) Air-operated remote control valves must be provided with self-
indicating lines at the control boards that indicate the desired valve 
positions, such as open or closed.
    (h) Suitable drains must be provided at low points of piping 
systems.
    (i) Valves and cocks must be easily accessible. Valves attached to 
the shell of the vessel or to sea chests located below deck plating 
must be operable from above the deckplates.
    (j) When welded fabrication is employed, a sufficient number of 
detachable joints must be provided to facilitate maintenance of 
machinery.
    (k) Piping systems used where the fluid temperature exceeds 150 
[deg]F must be suitably insulated as necessary to preclude injury to 
personnel.
    (l) Where pipes are run through dry cargo spaces they must be 
protected from mechanical injury by a suitable enclosure or other 
means.

required stop and stop-check valves (see paragraph (b) of this 
section), must have a design pressure which exceeds the maximum 
allowable working pressure of the boiler by either 25 percent or 225 
psig, whichever is less. The value of allowable stress for design 
purposes must be selected as described in Sec.  56.07-10(e) at a 
temperature not below that for saturated steam at the maximum allowable 
working pressure of the boiler.
    (4) Feed pumps for water tube boilers must have freshwater 
connections only.

Sec.  56.50-50  Bilge and ballast piping.

    (a)(1) The requirements of SOLAS Chapter II-1 regulation 35-1 
(incorporated by reference, see Sec.  56.01-2) for passenger and cargo 
ships are considered equivalent to this section.
    (2) All vessels except unmanned barges must be provided with a 
satisfactory bilge pumping plant capable of pumping from and draining 
any watertight compartment except for ballast, oil and water tanks. The 
bilge pumping system must be capable of operation under all practicable 
conditions after a casualty whether the ship is upright or listed.
    (3) Arrangements must be made whereby water in the compartments 
will drain to the suction pipes. Where piping is led through the 
forepeak, see Sec.  56.50-1(b).
    (4) Where the vessel is to carry flammable liquids with a 
flashpoint below 23 [deg]C (74 [deg]F) in enclosed cargo spaces, the 
bilge-pumping system must be designed to ensure against inadvertent 
pumping of such liquids through machinery spaces.
    (5) For vessels constructed on or after June 9, 1995, and on an 
international voyage, arrangements must meet the requirements of SOLAS 
Chapter II-1 regulation 35-1 to drain the enclosed cargo spaces on 
either the bulkhead deck of a passenger vessel or the freeboard deck of 
a cargo vessel.
    (b) Passenger vessels must have provision made to prevent the 
compartment served by any bilge suction piping from being flooded in 
the event the pipe is severed or otherwise damaged by collision or 
grounding in any other compartment. Where the piping is located within 
one-fifth of the beam of the side of the vessel or is in a duct keel, a 
nonreturn valve must be fitted to the end of the pipe in the 
compartment which it serves.
    (c)(1) Each bilge suction must lead from a manifold unless 
otherwise approved by the Marine Safety Center.

[[Page 57954]]

As far as practicable, each manifold must be in, or capable of remote 
operation from, the same space as the bilge pump. In either case, the 
manifold must be capable of being locally controlled from the 
floorplates. As far as practicable, each overboard-discharge valve for 
a bilge system must comply with the requirements governing location and 
accessibility for suction manifolds. Except as otherwise permitted by 
paragraph (c)(4) of this section for a vessel employing a common-rail 
bilge system, each bilge-manifold valve controlling a bilge suction 
from any compartment must be of the stop-check type.
* * * * *
    (3) * * *
    (iii) The stop valve or the stop-check valve is power-driven, is 
capable of remote operation from the space where the pump is, and is 
capable of manual operation.
* * * * *
    (d) The internal diameter of bilge suction pipes including 
strainers must be determined by Formulas 1 and 2 to 56.50-50(d), except 
that the nearest commercial size not more than one-fourth inch under 
the required diameter may be used. * * *
    (1) For suctions to each main bilge pump, use Formula 1 to 56.50-
50(d). For branch suctions to cargo and machinery spaces, use Formula 2 
to 56.50-50(d).
* * * * *
    (f) * * *
    (1) On passenger vessels propelled by steam and operating on an 
international voyage or on ocean, coastwise, or Great Lakes routes, the 
main circulating pump is to be fitted with a direct bilge suction for 
the machinery space. The diameter of such suctions must not be less 
than two-thirds the diameter of the main sea injection. Other 
independent power pumps in the machinery space may be approved by the 
Commandant if the main circulating pump is not suitable.
    (2) On passenger vessels propelled by internal combustion engines 
and operating on an international voyage or on ocean, coastwise, or 
Great Lakes routes, the largest available pump in the engine room is to 
be fitted with the direct bilge suction in the machinery space. The 
area of the suction pipe is to be equal to the full suction inlet of 
the pump.
* * * * *
    (g) Each individual bilge suction must be fitted with a suitable 
strainer having an open area of not less than three times that of the 
suction pipe. In addition a mud box or basket strainer must be fitted 
in an accessible position between the bilge suction manifold and the 
pump.
* * * * *
    (j) When dry cargo is to be carried in deep tanks, arrangement must 
be made for blanking-off the oil and ballast lines. The bilge suctions 
must be blanked-off when oil or ballast is carried.
    (k) Where bilge and ballast piping is led through tanks, except 
ballast piping in ballast tanks, means must be provided to minimize the 
risk of flooding of other spaces due to pipe failure. In this regard, 
such piping may be in a watertight pipe tunnel, or the piping may be of 
Schedule 80 pipe wall thickness, fitted with expansion bends, with all 
joints welded. Alternative designs may be approved by the Marine Safety 
Center. Where a pipe tunnel is installed, the watertight integrity of 
the bulkheads must be maintained. No valve or fitting may be located 
within the tunnel if the pipe tunnel is not of sufficient size to 
afford access.

pump must develop a suction velocity of not less than 400 feet per 
minute and a corresponding capacity based on the size of bilge main 
piping required by Sec.  56.50-50(d)(1).
    (2) Alternatively, the minimum pump capacity, Q, in m\3\/hr may be 
based on the following formula:


[[Page 57955]]


Q = 5.75d\2\/1000, where d = diameter of the main bilge suction piping, 
in mm.

    (3) For vessels of less than 65 feet in length not engaged on 
international voyages, the pump must have a minimum capacity of 25 
gallons per minute and need not meet the velocity requirement of this 
paragraph.
* * * * *
    (e) * * *
    (2) For non-self-propelled vessels requiring two bilge pumps, these 
pumps, insofar as practicable, must be located in separate watertight 
machinery spaces. When the location of bilge pumps in separate 
watertight compartments is not possible, the Marine Safety Center will 
consider alternate arrangements.

Sec.  56.50-60  Systems containing oil.

    (a)(1) Oil-piping systems for cargo or fuel oil must be separate 
from other piping systems as far as practicable, and positive means 
must be provided to prevent interconnection in service.
    (2) Fuel oil and cargo oil systems may be combined if the cargo oil 
systems contain only Grade E oils.
    (3) Oil pumps must have no discharge connections to fire mains, 
boiler feed systems, or condensers.
    (b) * * *
    (1) Each drain from a heating coil as well as each drain from an 
oil heater must run to an inspection tank or other suitable oil 
detector.

exits from the tank or adjacent tanks. Valves for local control outside 
the tanks must meet paragraph (d)(1) of this section.
    (3) * * *
    (i) Valve actuators must be capable of closing the valves under all 
conditions, except during physical interruption of the power system 
(for example, from cable breakage or tube rupture). Fluid power 
actuated valves, other than those opened against spring pressure, must 
be provided with an energy storage system which is protected, as far as 
practicable, from fire and mechanical damage. The energy storage system 
must be used for no other purpose and must have sufficient capacity to 
cycle all connected valves from the initial valve position to the 
opposite position and return. The cross connection of this system to an 
alternate power supply will be given special consideration by the 
Marine Safety Center.
    (ii) The valve must have a local power actuator to both open and 
close the valve, unless local manual opening operation will not prevent 
remote closing of the valve.
* * * * *
    (iv) The valve must be provided with a means of emergency manual 
operation to both open and close the valve regardless of the status of 
the power operating system. Such manual operation may interfere with

    (b) Installation. (1) All fuel pipes, pipe connections, and 
accessories must be readily accessible, protected against mechanical 
injury, and effectively secured against excessive movement and 
vibration by the use of soft nonferrous metal liners or straps. Where 
passing through steel decks or bulkheads, fuel lines must be protected 
by close fitting ferrules or stuffing boxes. Refer to Sec.  56.30-25 
for tubing joint installations.
    (2) A short length of suitable metallic or nonmetallic flexible 
tubing or hose, or a loop of annealed copper tubing, must be installed 
in the fuel-supply line at or near the engine to prevent damage by 
vibration.
    (i) If nonmetallic flexible hose is used, it must meet the 
requirements of Sec.  56.60-25(b) for fuel service.
    (ii) Flexible hose connections should maintain metallic contact 
(continuity) between the sections of the fuel-supply lines; however, if 
they do not, the fuel tank must be grounded.

access through the vent to below deck must be at least 30 inches (760 
mm) on the freeboard deck and 17\1/2\ inches (450 mm) on the 
superstructure deck. On Great Lakes vessels, the height from the deck 
to any point where water may gain access through the vent to below deck 
must be at least 30 inches (760 mm) on the freeboard deck, 24 inches 
(610 mm) on the raised quarterdeck, and 12 inches (305 mm) on other 
superstructure decks. Where the height of vents may interfere with the 
working of the vessel, a lower height may be approved by the Marine 
Safety Center provided the vent cap is properly protected from 
mechanical damage. For barges in inland service, the vents must extend 
at least six inches above the deck.
    (7) * * *
    (i) A ball check valve where the ball float, normally in the open 
position, will float up and close under the action of a submerging 
wave. The valve must be designed so that the effective clear discharge 
area through the valve with the float in the open position is not less 
than the inlet area of the vent pipe to which the valve is connected; 
or
* * * * *
    (10) The diameter of each vent pipe must not be less than 1\1/2\ 
inches nominal pipe size for freshwater tanks, 2 inches nominal pipe 
size for water ballast tanks, and 2\1/2\ inches nominal pipe size for

    The revisions read as follows:


Sec.  56.50-95  Overboard discharges and shell connections.

    (a)(1) All inlets and discharges led through the vessel's side must 
be fitted with efficient and accessible means, located as close to the 
hull penetrations as is practicable.
* * * * *
    (b) * * *
    (2) Discharges led through the shell originating either from spaces 
below the freeboard deck or from within enclosed superstructures and 
equivalent deckhouses on the freeboard deck as defined in Sec.  42.13-
15(i) of subchapter E (Load Lines) of this chapter, must be fitted with 
efficient and accessible means for preventing water from passing 
inboard. Normally each separate discharge must have one automatic 
nonreturn valve with a positive means of closing it from a position 
above the freeboard deck. Where, however, the vertical upward distance 
from the summer load line to the inboard end of the discharge pipe 
through which flooding can take place exceeds 0.01L, the discharge may 
have two automatic nonreturn valves without positive means of closing, 
provided that the inboard valve is always accessible for examination 
under service conditions. Where that vertical distance exceeds 0.02L a 
single automatic nonreturn valve without positive means of closing is 
acceptable. In an installation where the two automatic nonreturn valves 
are used, the inboard valve must be above the tropical load line. The 
means for operating the positive action valve must be readily 
accessible and provided with an indicator showing whether the valve is 
open or closed. A notice must be posted at the operating station to the 
effect that the valve must not be closed except as required in an 
emergency.
* * * * *
    (d)(1) Sea inlets and discharges, such as used in closed systems 
required for the operation of main and auxiliary machinery, as in pump 
connections or scoop injection heat exchanger connections, need not 
meet the requirements of paragraphs (b)(1) and (2) of this section but 
instead must be fitted with a shutoff valve located as near the shell 
plating as practicable, and may be locally controlled if the valve is 
located in a manned machinery space. These controls must be readily 
accessible above the floor plates. Manned machinery spaces include the 
main machinery space and are either attended by the crew or are 
automated in accordance with part 62 of this subchapter to be 
comparable to an attended space.
* * * * *
    (e) * * *
    (2) Seachests and other hull fittings must be as short as possible 
and located so as to minimize the possibility of being blocked or 
obstructed.
* * * * *
    (f) Valves required by this section and piping system components 
outboard of such required valves must be of a steel, bronze, or ductile 
cast iron specification listed in table 1 to Sec.  56.60-1. Lead or 
other heat sensitive materials having a melting point of 1,700 [deg]F. 
or less must not be used in such service where the deterioration of the 
piping system in the event of fire would give rise to danger of 
flooding. Brittle materials such as cast iron must not be used in such 
service. Where nonmetallic materials are used in a piping system, and 
shell closures are required by this section, a positive closure 
metallic valve is required (see also Sec.  56.60-25).
* * * * *
    (h) Where deck drains, soil lines, and sanitary drains discharge 
through the shell in way of cargo tanks on tank vessels, the valves 
required by this section must be located outside the cargo tanks. These 
valves must meet the material requirements of paragraph (f) of this 
section. The piping led through such tanks must be fitted with 
expansion bends where required, and must be of steel pipe having a wall 
thickness of not less than Schedule 60, except that the use of suitable 
corrosion-resistant material of lesser thickness will be given special 
consideration by the Commandant. All pipe joints within the tanks must 
be welded. Soil lines and sanitary drains which pass through cargo 
tanks must be provided with nonreturn valves with positive means of 
closing or other suitable means for preventing the entrance of gases 
into living quarters.
    (i) Sea valves must not be held open or closed with locks.

\1\ Quench and temper heat treatment may be permitted when specifically authorized by the Commandant. In those
  cases the minimum average Charpy V-notch energy must be specially designated by the Commandant.
\2\ Other material specifications for product forms acceptable under part 54 for use at low temperatures may
  also be used for piping systems provided the applicable toughness requirements of this table 2 to Sec.   56.50-
  105 are also met.
\3\ Any repair method must be acceptable to the Commandant (CG-ENG), and welding repairs as well as fabrication
  welding must be in accordance with part 57 of this chapter.
\4\ The acceptability of several alloys for low temperature service is not intended to suggest acceptable
  resistance to marine corrosion. The selection of alloys for any particular shipboard location must take
  corrosion resistance into account and be approved by the Marine Safety Center.

    Note 1 to table 2 to Sec.  56.50-105: The ASTM standards listed in 
table 2 to Sec.  56.50-105 are incorporated by reference, see Sec.  
56.01-2.


Sec.  56.50-110  [Amended]

0
186. In Sec.  56.50-110(b), remove the words ``which is''.
0
187. Revise Sec.  56.60-1 to read as follows:


Sec.  56.60-1  Acceptable materials and specifications (replaces 123 
and Table 126.1 in ASME B31.1).

    (a)(1) The material requirements in this subpart must be followed 
in lieu of those in 123 in ASME B31.1 (incorporated by reference; see 
Sec.  56.01-2).
    (2) Materials used in piping systems must be selected from the 
specifications that appear in table 1 to Sec.  56.60-1 of this section 
or table Sec.  56.60-2, ASTM F1155 (incorporated by reference; see 
Sec.  56.01-2), or they may be selected from the material 
specifications of Sections I or VIII of the ASME BPVC (both 
incorporated by reference; see Sec.  56.01-2) if not prohibited by a 
regulation of this subchapter. Table 1 to Sec.  56.60-1(a) contains 
only pipe, tubing, and fitting specifications. Determination of 
acceptability of plate, forgings, bolting, nuts, and castings may be 
made by reference to the ASME BPVC as previously described. 
Additionally, accepted materials for use as piping system components 
appear in table Sec.  56.60-2. Materials conforming to specifications 
not described in this subparagraph must receive the specific approval 
of the Marine Safety Center. Materials listed in Table 126.1 of ASME 
B31.1 are not accepted unless specifically permitted by this paragraph.
    (b) Components made in accordance with the commercial standards 
listed in Table 56.60-1(b) of this section and made of materials 
complying with paragraph (a) this section may be used in piping systems 
within the limitations of the standards and within any further 
limitations specified in this subchapter.
    Note 1 to Sec.  56.60-1: Table 1 to Sec.  56.60-1 replaces Table 
126.1 in ASME B31.1 and sets forth specifications of pipes, tubing, and 
fittings intended for use in piping-systems. The first column lists 
acceptable standards from ASTM (all incorporated by reference; see 
Sec.  56.01-2); the second lists those from ASME (all incorporated by 
reference; see Sec.  56.01-2). The Coast Guard will consider use of 
alternative pipes, tubing, and fittings when it receives certification 
of their mechanical properties. Without this certification it will 
restrict use of such alternatives to piping-systems inside heat 
exchangers that ensure containment of the material inside pressure 
shells.

  compute wall thickness, the stress shown here must be applied as
  though taken from the stress tables. An additional factor of 0.8 may
  be required by Sec.   56.07-10(c) and (e).

[[Page 57962]]

 
\1\ For austenitic materials where two sets of stresses appear, use the
  lower values.
\2\ Type F (Furnace welded, using open hearth, basic oxygen, or electric
  furnace only) limited to Class II applications with a maximum service
  temperature of 450 [deg]F. Type E (ERW grade) limited to maximum
  service temperature of 650 [deg]F, or less.
\3\ Electric resistance welded pipe or tubing of this specification may
  be used to a maximum design pressure of 350 psig.
\4\ Refer to limitations on use of welded grades given in Sec.   56.60-
  2(b).
\5\ Use generally considered for Classes I-L and II-L applications. For
  Class I-L service only, the seamless grade is permitted. For other
  service refer to footnote 4 and to Sec.   56.50-105.
\6\ Furnace lap or furnace butt grades only. Limited to Class II
  applications only where the maximum service temperature is 450 [deg]F,
  or less.
\7\ Limited to Class II applications only where maximum service
  temperature is 300 [deg]F or less for straight seam, and 200 [deg]F or
  less for spiral seam.
\8\ Limited to Class II applications where the maximum service
  temperature is 300 [deg]F or less for straight seam and 200 [deg]F or
  less for spiral seam.
\9\ For Class I applications only the Class I Grade of the specification
  may be used.
\10\ When used in piping systems, a certificate must be furnished by the
  manufacturer certifying the mechanical properties at room temperature.
  Without this certification, use is limited to applications within heat
  exchangers.
\11\ Hydrostatic testing of these fittings is not required but all
  fittings must be capable of withstanding a hydrostatic test of 11/2
  times the design pressure.
\12\ Other acceptable iron castings are in UCI-23 and UCD-23 of Section
  VIII of the ASME BPVC. (See also Sec.  Sec.   56.60-10 and 56.60-15.)
  Acceptable castings of materials other than cast iron may be found in
  Sections I or VIII of the ASME BPVC.
\13\ Acceptable when complying with ANSI standards. Ductile iron is
  acceptable for temperatures not exceeding 650 [deg]F. For pressure
  temperature limitations refer to UCD-3 of Section VIII of the ASME
  BPVC. Other grades of cast iron are acceptable for temperatures not
  exceeding 450 [deg]F. For pressure temperature limitations refer to
  UCI-3 of Section VIII of the ASME BPVC.
\14\ For limitations in use refer to Sec.  Sec.   56.10-5(c) and 56.60-
  20.
\15\ Copper pipe must not be used for hot oil systems except for short
  flexible connections at burners. Copper pipe must be annealed before
  installation in Class I piping systems. See also Sec.  Sec.   56.10-
  5(c) and 56.60-20.
\16\ The stress values must be taken from UNF23 of Section VIII of the
  ASME BPVC for B75 annealed and light drawn temper as appropriate.
\17\ B68 is acceptable if provided with a mill hydrostatic or eddy
  current test.
\18\ Limited to pipe fittings and valves. See 46 CFR 56.60-15(d) for
  additional information.

  certificate must indicate the specification or grade of the materials
  as necessary to fully identify the materials. The materials must
  comply with the requirements in this subchapter governing the

Sec.  56.70-15  Procedure (modifies 127.4).

    (a) * * * (1) Qualification of welders and welding procedures is 
required and must comply with the requirements of part 57 of this 
subchapter.
    (2) Sections must be welded insofar as possible in the fabricating 
shop. Welding must not be done in severe weather conditions. Prior to 
welding Class I piping or low temperature piping, the fabricator must 
request a marine inspector to visit his plant to examine his 
fabricating equipment and to witness the qualification tests required 
by part 57 of this subchapter. One test specimen must be prepared for 
each process and welding position to be employed in the fabrication.
    (b) * * *
    (2) Girth butt welds in Class I, I-L, and II-L piping systems must 
be double welded butt joints or equivalent single welded butt joints 
for pipe diameters exceeding three-fourth inch nominal pipe size. The 
use of a single welded butt joint employing a backing ring (note 
restrictions in paragraph (b)(3)(iv) of this section) on the inside of 
the pipe is an acceptable equivalent for Class I and Class II-L 
applications, but not permitted for Class I-L applications. Single 
welded butt joints employing either an inert gas for first pass backup 
or a consumable insert ring may be considered the equivalent of a 
double welded butt joint for all classes of piping and is preferable 
for Class I-L and II-L systems where double butt welds cannot be used. 
A first pass inert gas backup is intended to mean that the inside of 
the pipe is purged with inert gas and that the root is welded with the 
inert gas metal arc (mig) or inert gas tungsten arc (tig) processes. 
For single welded joints, where possible, the inside of the joint must 
be examined visually to assure full penetration. Radiographic 
examination of at least 20 percent of single welded joints to check for 
penetration is required for all Class I and Class I-L systems 
regardless of size following the requirements of Sec.  56.95-10. 
Ultrasonic testing may be utilized in lieu of radiographic examination 
if the procedures are approved.
* * * * *
    (4) Tack welds that become part of the finished weld must be made 
by a qualified welder. Tack welds which have cracked must be removed.
* * * * *
    (6) * * *
    (i) The condition of finished welds must be suitable for 
radiographic and other nondestructive examinations when required by 
Sec.  56.95-10. * * *
    (ii) Reinforcements are permitted in accordance with table Sec.  
56.70-15.
* * * * *
    (8) * * *
    (ii) Any slag inclusion or porosity greater than specified as 
acceptable in PW-51 of Section I of the ASME BPVC (incorporated by 
reference; see Sec.  56.01-2).
    (iii) Undercuts in the external surfaces of butt welds more than 
\1/32\-inch deep.
* * * * *
    (c) Longitudinal butt welds. Longitudinal butt welds in piping 
components not made in accordance with the standards and specifications 
listed in Sec.  56.60-1 must meet the requirements of paragraph 127.4.3 
of ASME B31.1 (incorporated by reference; see Sec.  56.01-2).
    (d) * * *

[[Page 57966]]

    (3) * * * The fillet weld must be deposited in a minimum of two 
passes, unless specifically approved otherwise. * * *
    (4) Sleeve and socket type joints may be used in Class II piping 
systems without restriction as to size of pipe or tubing joined. The 
fillet welds must be deposited in a minimum of two passes, unless 
specifically approved otherwise. Requirements for joints employing 
socket weld and slip-on flanges are in Sec.  56.30-10.
    (e) Seal welds. (1) Where seal welding of threaded joints is 
performed, threads must be entirely covered by the seal weld.
* * * * *
    (g) * * *
    (1) Figures 127.4.8A, B, and C of ASME B31.1 show typical details 
of branch connections with and without added reinforcement. See also 
figure Sec.  56.70-15(g)(3) for additional pipe connections.

216. Revise Sec.  56.95-10 to read as follows:


Sec.  56.95-10  Type and extent of examination required.

    (a) General. The types and extent of nondestructive examinations 
required for piping must be in accordance with this section and Table 
136.4 of ASME B31.1 (incorporated by reference; see Sec.  56.01-2). In 
addition, a visual examination must be made.
    (1) 100 percent radiography is required for all Class I, I-L, and 
II-L piping with wall thickness equal to or greater than 10 mm (.393 
in.).
    Note 1 to paragraph (a)(1): Throughout this this section, where for 
some reason, such as joint configuration, radiography is not 
applicable, another approved examination may be utilized.
    (2) Nondestructive examination is required for all Class II piping 
equal to or greater than 18 inches nominal diameter regardless of wall 
thickness. Any test method acceptable to the Officer in Charge, Marine 
Inspection may be used.
    (3) Nondestructive examinations of other piping systems are 
required only when deemed necessary by the Officer in Charge, Marine 
Inspection (OCMI).
    (b) Visual examination. Visual examination consists of observation 
by the marine inspector either before, during, or after manufacture, 
fabrication, assembly or test. All welds, pipe and piping components 
must comply with the limitations on imperfections specified in the 
product specification or with the limitations on imperfections 
specified in Sec.  56.70-15(b)(7) and (8), and (c), as applicable.
    (c) Nondestructive types of examinations--(1) 100 Percent 
radiography. Where 100 percent radiography is required, each weld in 
the piping must be completely radiographed. If a butt weld is examined 
by radiography, for either random or 100 percent radiography, the 
method used must be as follows:
    (i) X-ray or gamma ray method of radiography may be used. The 
selection of the method must be dependent upon its adaptability to the 
work being radiographed. The procedure to be followed must be as 
indicated in PW-51 of Section I of the ASME BPVC (incorporated by 
reference; see Sec.  56.01-2).
    (ii) If a piping component or a weld other than a butt weld is 
radiographed, the method used must be in accordance with UW-51 of 
Section VIII of the ASME BPVC (incorporated by reference; see Sec.  
56.01-2).
    (2) Random radiography. Where random radiography is required, one 
or more welds may be completely or partially radiographed. Random 
radiography is desirable in field welding, where conditions such as 
position, temperatures, and cleanliness are not as controlled as in 
shop welding. It may be employed whenever an Officer in Charge, Marine 
Inspection questions a pipe weld not otherwise required to be tested. 
The standards of acceptance are the same as for 100 percent 
radiography.
    (3) Ultrasonic. Where 100 percent ultrasonic testing is specified, 
the entire surface of the weld being inspected must be covered using 
careful methods to be sure that a true representation of the actual 
conditions is obtained. The procedures to be used must be submitted to 
the Commandant for approval.
    (4) Liquid penetrant. Where liquid penetrant examination is 
required, the entire surface of the weld being examined must be 
covered. The examination must be performed in accordance with appendix 
VIII to Section VIII of the ASME BPVC. The following standards of 
acceptance must be met:
    (i) All linear discontinuities and aligned penetrant indications 
revealed by the test must be removed. Aligned

[[Page 57969]]

penetrant indications are those in which the average of the center-to-
center distances between any one indication and the two adjacent 
indications in any straight line is less than three-sixteenths inch. 
All other discontinuities revealed on the surface need not be removed 
unless the discontinuities are also revealed by radiography, in which 
case the pertinent radiographic specification applies.
    (ii) [Reserved]
    (5) Magnetic particle. Where magnetic particle testing is required, 
the entire surface of the weld being examined must be covered. The 
testing must be performed in accordance with Appendix VI to Section 
VIII of the ASME BPVC. The following standards of acceptance are 
required for welds. All linear discontinuities and aligned indications 
revealed by the test must be removed. Aligned indications are those in 
which the average of the center-to-center distances between any one 
indication and the two adjacent indications in any straight line is 
less than three-sixteenths inch. All other revealed discontinuities 
need not be removed unless the discontinuities are also revealed by 
radiography, in which case the requirements of paragraph (c)(1) of this 
section must be met.

    (a) An initial service leak test and inspection is acceptable when 
other types of test are not practical or when leak tightness is 
conveniently demonstrable due to the nature of the service. One example 
is piping where shut-off valves are not available for isolating a line. 
Others may be systems for service water, condensate, plant and 
instrument air, etc., where checking out of pumps and compressors 
afford ample opportunity for leak tightness inspection prior to full-
scale operation.

Sec.  59.10-5  Cracks.

* * * * *
    (h) All cracks permitted to be repaired under this subpart must be 
excavated to sound metal by grinding, flame or arc gouging or chipping 
out the defective metal to form a clean welding groove. Either a V 
groove or U groove wherein complete penetration of the weld metal is 
secured may be used. After excavation is completed and prior to 
welding, the excavated area must be examined by magnetic particle, dye 
penetrant, or other acceptable test method. When the reverse side of 
the weld is accessible the root of the weld must be chipped or ground 
out to insure a clean surface of the originally deposited metal and the 
resultant groove welded to obtain a sound weld having complete 
penetration. When the weld cannot be back chipped because the reverse 
side is inaccessible, a backing strip or other approved means of 
assuring full penetration must be employed.
    (i) During welding of cracks a preheat must be maintained by 
controlled temperatures. The degree of preheat must be determined by 
the rules listed in accordance with the materials P-number groupings of 
PW-38, Section I of the ASME BPVC, appendix R, Section VIII of the ASME 
BPVC, and Appendix D, Section IX of the ASME BPVC (all incorporated by 
reference; see Sec.  59.01-2). For thicknesses exceeding three-fourths 
inch, suitable U grooves should be employed. A welding sequence must be 
used so as to equalize welding stresses.
    (j) Postweld heat treatment of repaired cracks must be performed in 
accordance with the rules specified in PW-39, Section I of the ASME 
BPVC and UW-40, Section VIII of the ASME BPVC for boilers and pressure 
vessels respectively.
    (k) Welded repairs of cracks must be nondestructively tested in

* * * * *
    (d) Where stayed sheets have corroded to a depth not exceeding 40 
percent of their original thickness, they may be reinforced or built up 
by welding. Where the staybolts are fitted with riveted heads, the 
staybolts in the reinforced area must be renewed, but where the 
staybolts are fitted with nuts, the nuts may be removed and after 
reinforcing has been applied, collars may be welded around the 
staybolts in lieu of the nuts. Such reinforced areas must not exceed 
400 square inches nor more than 30 inches in one direction. Two such 
areas in any one plate may be reinforced: Provided, that the distance 
between the reinforced surfaces is not less than 30 inches.
    (e) When the corroded portion of a staybolted surface exceeds 400 
square inches, it is permissible to make repairs by cutting out the 
defective portion and replacing it with a new plate, the edges of the 
new plate to be welded in position. In such cases, new staybolts must 
be fitted, and where welding is performed through a line of staybolts, 
welded collars must be used to attach the staybolts.
    (f) Eroded seams of welded pressure vessels may be repaired by 
rewelding the wasted portion. The wasted section of the seam must be 
excavated sufficiently by grinding, flame or arc gouging or chipping to 
ensure proper weld penetration. Rewelded seams must be nondestructively 
tested in accordance with Section VIII of the ASME BPVC (incorporated 
by reference, see Sec.  59.01-2).

Sec.  61.05-10  Boilers in service.

    (a) Each boiler, including superheater, reheater, economizer, 
auxiliary boiler, low-pressure heating boiler, and unfired steam 
boiler, must be available for examination by the marine inspector at 
intervals specified by table Sec.  61.05-10, and more often if 
necessary, to determine that the complete unit is in a safe and 
satisfactory condition.
* * * * *
    (f) The marine inspector may require any boiler to be drilled or 
gaged to determine actual thickness any time its safety is in doubt. At 
the first inspection for certification after a firetube or flue boiler 
has been installed for 10 years, it must be gaged to determine the 
extent of deterioration. Thickness will be measured at or near the 
waterline, at the bottom and at such other places deemed necessary by 
the marine inspector. Examination may be by drilling or a 
nondestructive means acceptable to the marine inspector. Prior to the 
use of a nondestructive method of examination, the user must 
demonstrate to the marine inspector that results having an accuracy 
within plus or minus 5 percent are consistently obtainable.
    (g) If the thickness is found to be less than the original 
thickness upon which the maximum allowable working pressure (MAWP) was 
based, the MAWP must be recalculated. The thickness of the thinnest 
measured portion must be used in this calculation. Either the design 
formulas given in this subchapter or the ones in effect when the boiler 
was contracted for or built may normally be used in this recalculation. 
In no case will an increase in the pressure allowed be made.

Sec.  61.10-5  Pressure vessels in service.

* * * * *
    (g) Bulk storage tanks. (1) Each bulk storage tank containing 
refrigerated liquefied CO2 for use aboard a vessel as a 
fire-extinguishing agent must be subjected to a hydrostatic test of 1.5 
times the maximum allowable working pressure in the 10th year of the 
installation and at 10-year intervals thereafter. After the test, the 
tank should be drained and an internal examination made. Parts of the 
jacket and lagging designated by the marine inspector must be removed 
at the time of the test so the marine inspector may determine the 
condition of the tank.
    (2) In lieu of the requirements contained in paragraph (g)(1) of 
this section, in the 10th year of installation and at 10-year intervals 
thereafter, each bulk storage tank containing refrigerated liquefied 
CO2 for use aboard a vessel as a fire-extinguishing agent 
which contains a manhole or means to enter, may undergo an internal 
examination by a marine inspector. Bulk storage tanks which have been 
satisfactorily examined internally by a marine inspector and in which 
no defects have been found which impair the safety of the pressure 
vessel will not require a hydrostatic test. When a defect is found 
during the internal examination that, in the judgment of the marine 
inspector, may affect the safety of the pressure vessel, the pressure 
vessel must be hydrostatically tested at a pressure of 1.5 times the 
maximum allowable working pressure, unless alternative means, 
acceptable to the Officer In Charge, Marine Inspection, are used to 
ensure the safe operation of the pressure vessel.
