Electrical Equipment in Hazardous Locations

AGENCY: Coast Guard, DHS.

ACTION: Final rule.

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

SUMMARY: The Coast Guard is issuing regulations applicable to newly
constructed mobile offshore drilling units (MODUs), floating outer
continental shelf (OCS) facilities, and vessels other than offshore
supply vessels (OSVs) that engage in OCS activities. The regulations
expand the list of acceptable national and international explosion
protection standards and add the internationally accepted independent
third-party certification system, the International Electrotechnical
Commission System for Certification to Standards relating to Equipment
for use in Explosive Atmospheres (IECEx), as an accepted method of
testing and certifying electrical equipment intended for use in
hazardous locations. The regulations also provide owners and operators
of existing U.S. MODUs, floating OCS facilities, vessels other than
OSVs, and U.S. tank vessels that carry flammable or combustible
cargoes, the option of following this compliance regime as an
alternative to the requirements contained in existing regulations.

DATES: This final rule is effective April 30, 2015.
    The Director of the Federal Register has approved the incorporation
by reference of certain publications listed in this rule, effective
April 30, 2015.

II. Regulatory History

Notice of Proposed Rulemaking

    On June 24, 2013, we published a notice of proposed rulemaking
(NPRM) in the Federal Register entitled Electrical Equipment in
Hazardous Locations (78 FR 37760). The NPRM proposed requiring third-
party testing and certification of electrical equipment in hazardous
locations by a Coast Guard-accepted independent third-party laboratory
in order to achieve uniform standards between U.S. and foreign vessels
and floating facilities. We received several requests to extend the 90-
day comment period until November 30, 2013. We granted these requests
and announced the extension in the Federal Register (78 FR 58989) on
September 25, 2013. We received 23 comment letters on the NPRM, and
considered all of these comments in developing this final rule. In
section VI below, we inserted a table that summarizes the changes
between the NPRM and the final rule.

Advisory Committee

    In April 2013, the Coast Guard tasked the National Offshore Safety
Advisory Committee (NOSAC) to review and comment on a notice of policy
we published in the Federal Register (77 FR 71607) on December 3, 2012.
The policy recommended that electrical equipment on foreign mobile
offshore drilling units (MODUs) that had never operated on the outer
continental shelf (OCS), but were intended to do so, meet Chapter 6 of
the 2009 MODU Code of the International Maritime Organization (IMO) and
obtain equipment certification under the International Electrotechnical
Commission Certification to Standards relating to Equipment for use in
Explosive Atmospheres (IECEx) System. While NOSAC was reviewing the
notice of policy, we published the Electrical Equipment in Hazardous
Locations NPRM (78 FR 37760) in the Federal Register. The NPRM proposed
regulations similar to the recommendations contained in the notice of
policy. Unlike the notice of policy, however, the NPRM was not limited
to foreign MODUs but applied to all vessels and facilities that had
never operated on the outer continental shelf (OCS) but intended to.
Further, the NPRM proposed requiring that certification under the IECEx
System be conducted by Coast Guard accepted independent laboratories in
order to facilitate Coast Guard oversight of those laboratories. NOSAC
provided comments on the notice of policy and on the NPRM, and those
comments were considered in developing this final rule.

III. Background

    A key finding of the Coast Guard's investigation of the MODU
DEEPWATER HORIZON explosion, fire, and sinking emphasized the
importance of proper electrical equipment installations in hazardous
locations during oil drilling exploration on U.S. and foreign MODUs.
The Coast Guard, therefore, reviewed the existing regulations for
hazardous locations; specifically, the requirements for electrical
equipment testing and certification and the standards applicable to
U.S. and foreign MODUs, floating OCS facilities, and vessels that
engage in OCS activities.
    Currently, electrical equipment on U.S. vessels and floating
facilities that operate on the OCS must comply with 46 CFR subpart
111.105. This subpart adopts international and national standards and
requires the equipment to be tested and certified by a Coast Guard-
accepted independent third-party laboratory.
    In contrast, foreign vessels and floating facilities that engage in
OCS activities must meet the requirements of 33 CFR subchapter N.
Currently, foreign floating OCS facilities must meet the same
engineering standards as U.S. floating OCS facilities, while foreign
vessels engaged in OCS activities on the U.S. OCS do not meet the same
engineering standards as U.S. vessels. While the Coast Guard supports
the development and adoption of international vessel safety standards,
the existing safety requirements of the International Convention on the
Safety of Life at Sea, 1974 (SOLAS) do not completely account for the
specifics of hydrocarbon production, processing, storage, and handling
systems, and the 2009 IMO MODU Code, which provides a recommended SOLAS
equivalency for MODUs, is not a legally binding instrument. For
electrical equipment in hazardous locations, we believe this rule is
necessary to ensure that all vessels engaged in OCS activities meet the
same, OCS-specific safety standards. In this final rule, therefore, we
require that new foreign MODUs, floating OCS facilities and vessels
meet the same standards for explosion protection in hazardous areas as
their U.S. counterparts before operating on the OCS. Additionally,
through this final rule, we expand the list of acceptable standards for
existing and new vessels and facilities.

IV. Discussion of Comments and Changes

    As noted above, we received 23 comment letters in response to the
NPRM. Additionally, NOSAC submitted a report to the Coast Guard that
included their comments on the NPRM. We considered all of these
comments in the development of this final rule. The comments and our
responses have been grouped into subject-matter categories below. In
cases where the comment resulted in a change to the regulations
previously proposed in the NPRM, the change is specifically identified
and discussed.

Implementation Date

    The NPRM's proposed implementation date was 30 days after
publication of the final rule. Fourteen comments stated that was
unreasonable. These commenters explained that over 200 MODUs were
either under contract, under construction or due to be constructed in
the next 5 years and that the costs of changing the specifications for
the electrical equipment located in hazardous locations would be much
greater than that indicated in Section VI of the NPRM.
    We agree. While the estimates provided correspond to the global
MODU population currently under construction, a majority of which have

not historically sought to operate on the OCS, the associated burden on
vessels under construction is real. Thus, we have delayed the
implementation date of the requirements of 46 CFR subpart 111.108. The
requirements of 46 CFR subpart 111.108 will apply to MODUs, floating
OCS facilities, and vessels, other than offshore supply vessels
regulated under 46 CFR subchapter L, that are constructed after April
2, 2018 and that engage in OCS activities. Estimates of the affected
foreign flagged vessel population reside in the regulatory analysis
section of this final rule. The definition of ``constructed'' has been
added to 33 CFR 140.10 and 46 CFR 110.15-1(b). It is consistent with
the existing definition for ``constructed'' found in 46 CFR 170.055(f).
Constructed means either the date a keel is laid or the date that
construction identified with the vessel or facility has begun.
    Existing U.S. MODUs, floating OCS facilities, and vessels, other
than offshore supply vessels (OSVs), and U.S. tank vessels that carry
flammable or combustible cargoes may immediately use the expanded list
of explosion protection standards and IECEx certification regime
identified in this final rule in lieu of the existing requirements in
Sec. Sec.  111.105-1 through 111.105-15.

2009 IMO MODU Code

    The NPRM proposed the adoption of a selection of explosion
protection standards and certification schemes. Thirteen comments
suggested that the proposed regulations were unnecessary and that
compliance with the 2009 IMO MODU Code should be sufficient for all
vessels. Many of these comments further noted that the 2009 IMO MODU
Code already requires certification by an independent testing
laboratory. We agree in part. The Coast Guard supports the development
and adoption of international vessel safety standards. The Coast Guard
believes the 2009 IMO MODU Code provides helpful guidance for the
design and engineering of MODUs, particularly in supplementing SOLAS
with standards specific to hydrocarbon production, processing, storage,
and handling systems, and should be given appropriate effect by flag
administrations. However, the 2009 IMO MODU Code is not a legally
binding instrument and by its terms does not apply to vessels that are
not MODUs. Additionally, there are differing interpretations of the
``independent testing laboratory'' certification contained in the 2009
MODU Code. As the coastal state with jurisdiction, we find that it is a
necessary and reasonable safety measure to require that newly
constructed foreign vessels and floating facilities that engage in OCS
activities have uniform safety standards for explosion protection in
hazardous locations.

Cost of Compliance for Existing Foreign Vessels and Facilities

    Ten comments addressed the cost of bringing into compliance with
the proposed rule existing MODUs that are currently not operated on the
OCS but the owners or operators intend them to do so. Those comments
stated that the cost of bringing the existing vessels into compliance
would likely exceed the cost published in the NPRM. In addition to
required equipment recertification and replacement costs, there would
be a loss of revenue during necessary downtime for replacement of
equipment that could equal or exceed all other costs.
    We recognize that the costs to retrofit an existing MODU could be
prohibitive depending on the design, construction and type of operation
of an individual MODU. Because of this, we decided to make the final
rule applicable to vessels and facilities that are constructed after
April 2, 2018 and that engage in OCS activities. Existing vessels and
facilities will continue to be subject to the regulations and standards
effective at the time of their construction.
    Similarly, one comment recommended that the Coast Guard address
electrical equipment in hazardous locations on MODUs currently on the
OCS. The Coast Guard disagrees. As explained earlier, this rule does
not require any existing vessel or facility to meet the requirements of
subpart 111.108 because the costs to retrofit existing equipment could
be prohibitive depending on the design, construction and type of
operation of an individual vessel or facility.
    One comment stated that the Coast Guard should address electrical
equipment in hazardous locations on foreign oil and chemical tankers
and gas carriers entering U.S. ports. These vessels are outside the
scope of this rulemaking, which is confined to vessels and facilities
engaged in OCS activities. Additionally, foreign oil and chemical
tankers and gas carriers are already subject to international standards
and to Coast Guard inspection for compliance with those standards.

Sister Vessels of Vessels Already Operating on the OCS

    Four comments requested that the final rule not apply to sister
vessels of vessels already operating on the OCS. They argued that these
vessels are identical in design to those existing vessels that the
Coast Guard is excluding from the requirements of this final rule.
    Under the NPRM, vessels new to the OCS would have been subject to
the new requirements, whereas vessels and facilities that had
previously operated on the OCS would not. In this final rule, we have
changed the applicability to include only those vessels and facilities
that are constructed after April 2, 2018 and that engage in OCS
activities. This final rule, therefore, does not place new requirements
on any existing vessels or facilities nor any vessel or facility that
is constructed on or before April 2, 2018. Existing vessels or
facilities or those constructed on or before April 2, 2018 will remain
subject to the regulations and standards effective at the time of their
construction and will remain subject to Coast Guard inspection. Any
vessel or facility constructed after the implementation date will be
subject to the requirements of 46 CFR subpart 111.108 before operating
on the OCS.

Coast Guard Independent Laboratory Requirement

    Eleven comments addressed the proposed requirement in 46 CFR
111.108-3 requiring the testing and certification of electrical
equipment in hazardous locations by an independent laboratory. The
definition of independent laboratory in the Coast Guard's Electrical
Engineering regulations is contained in 46 CFR 110.15-1, and means a
laboratory accepted by the Coast Guard using the independent laboratory
criteria found in 46 CFR 159.010. Commenters stated that this
requirement is burdensome and unnecessary, particularly for Ex
Certification Bodies (ExCBs) and Ex Testing Laboratories operating
under the IECEx System. Additionally, these commenters were concerned
that there were not enough independent laboratories accepted by the
Coast Guard, particularly within the IECEx System, to meet the demands
for equipment certifications necessary to comply with this final rule.
Further, the commenters stated that requiring Coast Guard-accepted
independent laboratories undermines use of international standards,
foreign flag administrations, and Recognized Organizations.
    We disagree. First, there are differing interpretations of the
``independent testing laboratory'' certification contained in the 2009
MODU Code. U.S. MODUs, vessels and floating facilities, have been
subject to independent third-party testing for over 30 years because we
believe it is a critically important

element in preventing accidental explosions in hazardous locations. As
the coastal state with jurisdiction, we find that it is a necessary and
reasonable safety measure to require that newly constructed foreign
vessels and floating facilities that engage in OCS activities have
uniform safety standards for explosion protection in hazardous
locations. This final rule, therefore, requires compliance with uniform
explosion protection standards and certification regimes. The
requirement to use Coast Guard-accepted independent laboratories allows
the Coast Guard reasonable oversight of laboratories located worldwide
and is consistent with our existing regulations for U.S. vessels and
facilities engaged in OCS activities. Currently, the majority of ExCBs
are Coast Guard-accepted independent laboratories. We have contacted
all ExCBs to suggest that they apply for acceptance. We expect that if
the demand is present, additional ExCBs will apply for acceptance.
Because this final rule applies to new vessels and facilities
constructed after April 2, 2018, we expect system designers, equipment
manufacturers, and independent laboratories will be able to smoothly
transition from existing international standards to the requirements of
this final rule. Finally, the existing SOLAS standards do not
completely account for the particularities of vessels designed and
constructed for OCS activities, and the 2009 IMO MODU Code is neither
mandatory nor applicable to all vessels. Therefore, implementation of a
domestic standard for electrical equipment in hazardous locations is
necessary to ensure that all vessels engaged in U.S. OCS activities
meet uniform safety standards particular to OCS activities and does not
undermine international standards or organizations.
    In a separate rulemaking, the Coast Guard published an interim rule
on August 18, 2014 (79 FR 48894) for U.S. offshore supply vessels
greater than 6,000 GT ITC. That interim rule also recognized the IECEx
System for certification of electrical equipment in hazardous
locations. Unlike section 111.108-3(b)(3) of this final rule, 46 CFR
111.106-3(b)(3)(iii) of the interim rule does not require certification
of electrical equipment in hazardous locations to be done by a Coast
Guard accepted independent laboratory. The Coast Guard recognizes the
inconsistency between 46 CFR 111.106-3(b)(3)(iii) of the interim rule
and 46 CFR 111.108-3(b)(3) of this final rule and intends to align 46
CFR 111.106-3(b)(3)(iii) with this final rule in a future rulemaking.

ATEX Equipment Certified by a Third-Party Independent Laboratory

    Eight comments suggested the Coast Guard accept electrical
equipment with certification issued under the European Commission
Directive (94/9/EC) on equipment and Protective Systems Intended for
use in Potentially Explosive Atmospheres (ATEX Directive or ATEX).
    We disagree. ATEX certification does not require independent third
party testing for all types of equipment. It also does not ensure that
electrical equipment installed in hazardous locations is fully tested
to relevant standards. When foreign MODUs and vessels have electrical
equipment installed in hazardous locations that is not independently
tested, there is not the same level of safety for explosion protection
in hazardous areas as required of U.S. vessels and floating facilities
that operate on the OCS and that are required to meet 46 CFR subpart
111.105. The ATEX Directive is a European conformity assessment scheme
designed to facilitate trade within Europe and is based on ``Essential
Health and Safety Requirements.'' Additionally, the ATEX Directive is
currently not applicable to seagoing vessels or MODUs and it is our
experience with ATEX certification that it can be difficult to
determine the extent of testing performed by the ``notified body \1\
''.
---------------------------------------------------------------------------

    \1\ A notified body is an organization ``appointed by EU Member
States, either for approval and monitoring of the manufacturers'
quality assurance system or for direct product inspection.'' http://ec.europa.eu/enterprise/glossary/index_en.htm, retrieved February
24, 2014.
---------------------------------------------------------------------------

    It is also important to recognize that some ATEX certified
electrical equipment may be acceptable under subpart 111.108 if it can
be demonstrated that the electrical equipment has been fully tested and
certified to the applicable standards contained in 46 CFR subchapter J
by an independent laboratory as defined in 46 CFR 110.15-1. Frequently,
equipment with ATEX certification also has certifications acceptable
under 46 CFR 111.108-3 of this final rule.
    Two comments requested that the Coast Guard clarify a statement in
CG-ENG Policy Letter No. 01-13, Alternate Design and Equipment Standard
for Floating Offshore Installations (FOI) and Floating Production,
Storage, and Offloading (FPSO) Units on the U.S. Outer Continental
Shelf, of June 26, 2013. For hazardous locations, the policy letter
states that electrical equipment certified under the ATEX scheme will
not be accepted by the Coast Guard. As explained above, if the
equipment is also certified in accordance with one of the acceptable
methods listed in 46 CFR 111.108-3, in addition to its ATEX
certification, then the equipment is acceptable under 46 CFR 111.108-3
of this final rule.

Class I, Special Division 1 Hazardous Locations

    Three comments said the proposed use of Class I, Special Division 1
in 46 CFR 111.108-3(e) may cause confusion as it is not a term
recognized by the National Fire Protection Association's (NFPA)
standard, NFPA 70, National Electrical Code (NEC), We disagree and have
not revised this section. Class I, Special Division 1 is intended to be
equivalent to Class I, Zone 0, and is consistent with Informational
Note No. 2 of Article 500.5(B)(3) of NFPA 70. Coast Guard regulations
have long recognized that certain spaces such as cargo pump rooms and
cargo tanks are more hazardous than other Class I, Division 1
locations. For these hazardous locations, we limit the types of
permitted electrical installations. Use of the term ``Class I, Special
Division 1'' simplifies the designation of these locations.

Electrical Equipment Inspection and Maintenance Requirements

    Five comments recommended that the Coast Guard establish standards
for the design, installation, inspection, and maintenance of electrical
equipment in hazardous locations. Two comments suggested requiring an
onboard electrical equipment register that contains information
regarding electrical equipment and its inspection, maintenance, and
operational history. The commenters also suggest this information could
be reviewed by visiting Coast Guard marine inspectors or third-party
inspection personnel and could become part of a company's quality
system. We agree that competency and accurate recordkeeping are
critical to safety, but this recommendation is outside the scope of
this rulemaking.

``Operated on the OCS''

    Under the NPRM, vessels and facilities new to the OCS would be
subject to the NPRM, whereas vessels and facilities that had previously
operated on the OCS, would not. Two comments requested that the Coast
Guard more clearly define what constitutes having ``operated on the
OCS.'' Because this final rule now applies only to vessels and
facilities constructed after April 2, 2018, that engage in OCS
activities, we believe no

further elaboration is needed, because the phrase ``operated on the
OCS'' is no longer used.

BSEE-USCG MOA, OCS-8, Regarding MODUs

    Two comments requested clarification on the responsibilities of the
Coast Guard and of the Bureau of Safety and Environmental Enforcement
(BSEE) for electrical equipment in hazardous locations on MODUs under
the USCG/BSEE Memorandum of Agreement, OCS-8, signed June 4, 2013.
While the subject is outside the scope of this rulemaking because
neither agency's responsibilities with regard to regulating electrical
equipment located in hazardous locations are affected by this final
rule, it is relevant to understanding the regulatory requirements for
electrical equipment located in hazardous locations.
    BSEE and Coast Guard have a shared responsibility for safety on the
OCS. In general, the Coast Guard is responsible for the vessel or
facility and all of its supporting systems while BSEE is responsible
for systems related to the drilling and production of resources.
Classification of hazardous locations and design of electrical systems
is a vessel-wide or facility-wide task and the Coast Guard maintains a
holistic view of the vessel or facility. The Coast Guard, in this rule,
provides an expanded list of standards that are applicable to systems
under the Coast Guard's jurisdiction as explained in BSEE-USCG MOA OCS-
8. The electrical safety standards contained in BSEE's OCS regulations,
30 CFR part 250, are acceptable to the Coast Guard. Frequently,
drilling and production components will be installed on vessels or
facilities on a temporary or semi-temporary basis. In general, BSEE
oversees these systems and if they find them acceptable, their
installation is acceptable to the Coast Guard.

Class I, Division 2 and Class I, Zone 2

    Two comments suggested that electrical equipment in Division 2 or
Zone 2 locations be accepted without independent third-party
certification or be accepted with ATEX certification. The Coast Guard
agrees to the extent that applicable provisions of NFPA 70 and the 2009
IMO MODU Code permit. 46 CFR 111.108-3(b)(1) and (b)(2) incorporate by
reference Articles 500-504 and Article 505 of the NFPA 70. Articles
501.125(B) and 505.20(C) of the NFPA 70 allow the installation of
certain electrical equipment in these locations without independent
identification or listing if the equipment meets specific requirements
that reduce the risk of explosion. This final rule is not intended to
modify these standards. 46 CFR 111.108-3(b)(3) incorporates Chapter 6
of the 2009 IMO MODU Code and requires certification under the IECEx
System. The IECEx System requires independent certification for all
electrical equipment in hazardous areas. This final rule is not
intended to modify the IECEx System. Electrical system designers must
choose an explosion protection standards regime from the list of
acceptable options provided in 46 CFR 111.108-3 and comply with the
standards regime they chose.

American National Standards Institute (ANSI) and International Society
of Automation (ISA) Standards

    One comment requested that the Coast Guard incorporate the latest
ANSI/ISA safety standards for hazardous locations. The Coast Guard
agrees and notes that 46 CFR 111.108-3(b) incorporates the ANSI/ISA
series of standards incorporated in NFPA 70, as it did in the NPRM.

Certain Required Equipment Not Meeting Zone 2 Requirements

    Two comments noted that some required equipment located in
hazardous locations is not available as certified for Zone 2 areas,
such as search and rescue transponders. The Coast Guard agrees with
this comment, and notes that several standards included in this final
rule address this situation. The objective of this final rule is to
provide a selection of standards for certification of electrical
equipment in hazardous locations. Electrical equipment not meeting the
Class I, Zone 2 or Class I, Division 2 requirements, should be
installed as far as possible from hazardous locations, or if not
possible, located or installed in the least hazardous location.
Standards listed in 46 CFR 111.108-3 of this final rule do address
equipment such as this. Section 6.3.3 of IEC 61892-7:2007,\2\ which is
accepted by the 2009 IMO MODU Code, refers to an assessment for energy-
limited equipment and circuits that is provided in IEC 60079-15, ANSI/
ISA 60079-15, ANSI/ISA-12.12.01, and UL 1604. Similarly, non-third
party assessment provisions are provided in Article 501 of NFPA 70 for
electrical equipment without switching mechanisms, or similar arc
producing devices. These standards can be used when certain required
equipment is not available as certified for Zone 2 areas.

Acceptance of IECEx Certified Equipment

    One comment asked if equipment tested to the IECEx System but not
yet marked as such would be acceptable. The commenter explained that
equipment is sometimes delivered before the IECEx Certificate of
Compliance is issued. Another comment noted that equipment can be
certified under both the ATEX Directive and the IECEx System but only
have ATEX labeling. Finally, a comment requested acceptance of
equipment consisting of assemblies of IECEx certified components rather
than requiring a certificate for the entire assembly.
    These are compliance issues that can be very simple or very complex
depending on the type of equipment and will be addressed by the Marine
Safety Center (MSC) or cognizant Officer-in-Charge, Marine Inspection
on a case-by-case basis. When IECEx on any other Coast Guard accepted
independent third party certification is unclear, documentation must be
presented that demonstrates the equipment meets the applicable
requirements. Any equipment or assembly of equipment must meet all the
requirements of the IECEx System. It is not the Coast Guard's intent to
modify the IECEx System.

Ultra Low Sulfur (ULS) Diesel Fuels

    One comment requested that the Coast Guard consider lowering the
minimum flashpoint that defines hazardous locations, because Ultra Low
Sulfur (ULS) diesel fuels are being produced against a minimum
flashpoint of 52[deg] C, rather than the 60[deg] C minimum that has
served as the basis for both Coast Guard and IMO requirements to date.
We are unable to make this change in the final rule because it was not
proposed in the NPRM. The minimum flashpoint of 60[deg] C exists in
numerous standards and regulations including 46 CFR 111.105-29, 46 CFR
111.105-31, 46 CFR 58.01-10, numerous locations within SOLAS, and IEC
60092-502:1999. We may consider proposing a change to the minimum
flashpoint in a future rulemaking. This will provide the public the
opportunity to comment on the proposal. Until that occurs, the MSC can
accept arrangements that provide an equivalent level of safety in
accordance with 46 CFR 110.20-1.

IECEx Certified Equipment in Class I, Division 1 and Class I, Division
2 Locations

    One commenter requested that drill floor equipment that is IECEx
certified for Class I, Zone 1 or Class I, Zone 2 be

permitted on drill floors classified to Class I, Division 1 or Class I,
Division 2. Equipment certified using the zone classification system,
regardless of whether certification was by a Coast Guard-accepted
independent laboratory or IECEx ExCB, is permitted in locations that
are classified using the division classification system in accordance
with Article 501.5 of NFPA 70, NEC. The same commenter requested that
drill floors be allowed to be classified under both systems so that
both zone and division certified equipment could be used. We do not
favor one classification system over the other and we are not opposed
to dual classification, but we caution that great care must be taken.
While both systems offer comparable levels of safety the two systems
are not identical or interchangeable. Indiscriminate ``mixing and
matching'' of systems could result in errors that result in lower
levels of safety. This limits the benefit of dual classification.
Article 505.7 of NFPA 70 provides details on dual classification. Any
mixing of classification systems should be done in accordance with NFPA
70 to ensure that the requirements of 46 CFR subpart 111.108 are met.

V. Incorporation by Reference

    The Director of the Federal Register has approved the material in
Sec.  110.10-1 for incorporation by reference under 5 U.S.C. 552 and 1
CFR part 51. Copies of the material are available from the sources
listed in that section.

VI. Regulatory Analyses

    We developed this rule after considering numerous statutes and
Executive Orders (E.O.s) related to rulemaking. Below we summarize our
analyses based on these statutes or E.O.s.

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 both
costs and benefits, of reducing costs, of harmonizing rules, and of
promoting flexibility.
    This rule is not a significant regulatory action under section 3(f)
of Executive Order 12866 as supplemented by Executive Order 13563, and
does not require an assessment of potential costs and benefits under
section 6(a)(3) of that Order. The Office of Management and Budget
(OMB) has not reviewed it under that Order. Nonetheless, we developed
an analysis of the costs and benefits of the rule to ascertain its
probable impacts on industry.
    A summary of the changes between the NPRM and the final rule
follows:

Discussion of Applicable Regulatory Assessment Comments and Changes
    The Coast Guard received several comments on the published NPRM.
These comments have been grouped by topic, as several comments
addressed similar concerns, and are discussed in the following table.

               Table 2--NPRM Comment Topics and Responses
------------------------------------------------------------------------

------------------------------------------------------------------------
Implementation Date..........  Several commenters voiced their concern
                                that the 30 day period between
                                publication of the final rule and the
                                effective date of the requirements was
                                too brief and did not allow sufficient
                                time for vessel and facility owners to
                                come into compliance. Changing the
                                implementation date from 30 days to 3
                                years after publication of the rule
                                addresses this concern and provides
                                owners and operators of the affected
                                population the amount of time deemed
                                sufficient by both the Coast Guard and
                                commenters alike, to meet the
                                requirements of this rule.
Compliance costs for vessels   Several comments addressed the concern
 currently under contract or    that vessels currently under contract or
 construction.                  construction could face recertification
                                costs before the vessel has been
                                completed. For example, one such comment
                                stated, ``Proposed regulations will
                                block entry onto the OCS of over 200
                                MODUs, built to the 2009 MODU Code, that
                                are currently under contracting or
                                construction.'' The Coast Guard
                                acknowledges the potential cost
                                associated with vessels currently under
                                design or construction. Estimates
                                suggest that designs and contracts are
                                sometimes set as much as 3 years in
                                advance. It is for this reason that we
                                have changed the implementation date to
                                3 years after the publication of the
                                rule. A 3 year delayed implementation
                                date allows vessels currently under
                                contract or construction to remain
                                subject to the regulations in effect at
                                the time that their construction began.
                                Changing the implementation date to 3
                                years after the publication of the rule
                                allows owners and operators of vessels
                                currently under contract or construction
                                to avert any costs associated with the
                                requirements of this rule.

Existing foreign vessels and   Several comments addressed existing MODUs
 facilities.                    that do not currently operate on the OCS
                                but intend to operate on the OCS and the
                                cost of bringing them into compliance
                                with the regulations prescribed in the
                                NPRM. We recognize that the costs of
                                retrofitting and/or recertifying
                                existing MODUs could be prohibitive
                                depending on the individual MODU.
                                Because of this, we revised the rule's
                                applicability to include only those
                                vessels and facilities that are
                                constructed after April 2, 2018 and that
                                operate on the OCS. Existing vessels and
                                facilities or vessels and facilities
                                constructed on or before April 2, 2018
                                will continue to be subject to the
                                regulations and standards effective at
                                the time of their construction.
Accuracy of Recertification    Some commenters stated that the burden to
 Cost Model and Estimates.      industry would likely exceed the cost
                                published in the NPRM for existing
                                vessels/MODUs. In addition to required
                                equipment recertification and
                                replacement costs, there would be a loss
                                of revenue during necessary downtime for
                                replacement of equipment that could
                                equal or exceed all other costs. As
                                noted previously, due to the burden for
                                existing vessels or vessels currently
                                under contract or construction, the
                                Coast Guard modified the rule's affected
                                population to include only those vessels
                                and facilities that are constructed
                                after April 2, 2018 and that engage in
                                OCS activities.
Barriers to trade............  One commenter suggested the proposal
                                would impose U.S.-specific requirements
                                that are above and beyond international
                                norms, and would create a non-tariff
                                barrier to trade that would restrict the
                                availability of rigs for the U.S.
                                market. The Coast Guard does not foresee
                                any barriers to trade. Coast Guard used
                                NIST's process to notify foreign
                                governments of our proposed NPRM and no
                                comments were received as a result of
                                that outreach.
------------------------------------------------------------------------

Costs: U.S. Vessels
    We do not anticipate any costs to be borne by the U.S.-flagged
vessels that will be affected by this rule. The rule requires that all
U.S. vessels, excluding OSVs that are regulated under 46 CFR subchapter
L, that are constructed after April 2, 2018 and engage in OCS activity,
comply with the newly created subpart 111.108. U.S. flagged vessels
which fall within this scope are provided with an expanded list of
standards and certification options.
    Subpart 111.108 will not impose any burden on U.S. vessels due to
the nature of current industry practice. Because North American
certification of electrical equipment is generally to the most current
edition of the published reference standards,\3\ we do not anticipate
new equipment will be tested and certified to the standards referenced
in subpart 111.105 when more current, updated editions of the standards
are available.
---------------------------------------------------------------------------

    \3\ Confirmed by Principal Engineer--Global Hazardous Locations
Product Safety, UL LLC., 12/26/2012.
---------------------------------------------------------------------------

    The logic applied to U.S. vessels, excluding OSVs as discussed
above, applies to U.S. MODUs and floating OCS facilities as well. We do
not anticipate any cost burden associated with this rule to be imposed
on this vessel class. We believe this because the affected population
are those U.S. MODUs and floating OCS facilities that are constructed
after April 2, 2018. These vessels will be subject to subpart 111.108,
a subpart that contains the updated standards to which new equipment
will be certified. As with the vessels discussed earlier, in the
absence of subpart 111.108, new equipment would be built to the most
current standards as a matter of industry practice. Under this final
rule, this scenario will not require any costs to the vessel owner as
there is no change in the regulatory environment for U.S. MODUs and
floating OCS facilities.
    Under this final rule, all U.S. MODUs, floating OCS facilities,
vessels other than OSVs, and U.S. tank vessels may comply with this new
subpart in lieu of Sec. Sec.  111.105-1 through 111.105-15. We do not
foresee any additional costs to the owners of these vessels and
facilities by providing this option but if there are additional costs,
there is expected to be equal or greater benefit to the owner driving
the selection of this option. Currently, the regulations for electrical
installations in hazardous locations are contained in subpart 111.105.
This regulation will expand the available subparts to include subpart
111.108, while still allowing owners and operators the option to remain
subject to existing subpart 111.105.
Costs: Foreign Vessels
    While the modification of the affected population aids us in
estimating the effects of the proposed rulemaking, it does not further
refine the costs which are applied to the population. As some
commenters on the NPRM document have reinforced, the estimated costs
associated with the rule could vary widely. Industry costs were
constructed from a variety of elements, for example the cost of
certifying equipment or the opportunity cost of recertification of said
equipment. With the modification of the affected population we are able
to drop the opportunity cost from our analysis, which allows us to
further streamline our discussion of the costs for the rulemaking. What
remains is the cost associated with third party certification of
equipment.
    Currently, foreign vessels are not required to utilize third party
certified equipment in hazardous areas unless explicitly required by
their flag state. Implementation of the final rule will require
certification by a Coast Guard approved, independent laboratory which,
in effect, changes the baseline for newly constructed foreign vessels.
Foreign flagged vessels constructed 3 years after the implementation
date seeking entrance to the OCS in pursuit of OCS activities will be
required to utilize third party certified equipment where previously
this was not explicitly required. Our analysis of this baseline change
is clouded by the aggregate nature of the cost of certification. When
an entity purchases equipment for use in a hazardous location on a
vessel, the marginal cost of the certification element of the purchase
price is not itemized for the purchaser. The certification cost is
present in the purchase price as a value added component of the total
price of the equipment. As such, we are not able to explicitly
determine the marginal cost difference between equipment certified by a
third party and those without third party certification. Additionally,
the list of equipment present in these locations, and required to be
third party certified, is diverse. For example, one equipment list
obtained by the Coast Guard contained equipment which ranged in
complexity from a fluorescent light to elements of the tank temperature
monitoring system.
    While the cost estimation is obtuse, it is not insurmountable. We
have several elements which should allow us to construct a range for
the final rule's associated costs. On the high end of the

range, we have the cost to replace all of the electrical installations
in a representative vessel. While not specifically applicable to a
newly built vessel, it is an appropriate estimate of the costs
associated with replacement of electrical installations in hazardous
areas. This estimate contains the costs associated with replacement of
both the equipment and the certification on a U.S. flagged vessel,
which are already subject to the certification requirements in this
final rule.
    The $500,000 cost quote \4\ for replacement of the equipment
appropriate for a hazardous location on a vessel is useful as a cost
ceiling. The replacement cost for this equipment, contains that which
is associated with the third party certification, in addition to the
price of the equipment itself. This functions well as a price ceiling
as we can be sure that the marginal cost of third party certification
will fall below this point estimate, as it is not likely to be above
the full cost of the equipment with its associated certification.

    \4\ Regulatory Advisor--ExxonMobil, 8/14/2012.
---------------------------------------------------------------------------

    The cost floor is a function of costs potentially accrued to a
hypothetical vessel to be built in the future. In some cases these
vessels would be built to the certification specifications contained in
this final rule anyway, in which case they would accrue no additional
costs from this rule. However, due to the probable greater cost of
third-party-certified equipment, we can assume that, without this
rulemaking, some equipment would be installed without third party
certification. Table 3 presents the range.

Affected Population
    The Coast Guard-maintained MISLE database, contains records of all
applicable vessels operating on the OCS in pursuit of OCS activities.

    Over the past 10 years, 17 foreign vessels have been built which
would fall under this rule's application. The database was filtered to
include foreign vessels, those vessel classes which would potentially
be on the OCS in pursuit of OCS activities, and have build years within
the past decade. Evaluation of this data found that on average, 2
foreign vessels are built per year which could seek entrance to the US
OCS in pursuit of OCS activities.
    Therefore, the range of costs associated with this rulemaking will
fall between $0 (2 Vessels * $0) and $1,000,000 (2 vessels * $500,000)
per year with an average per year cost of $500,000 (2 vessels *
$250,000).

NPRM vs Final Rule
    Burden estimates in the NPRM were $800,000 per year. With the
changes that the final rule makes to the affected population, the
yearly costs have been reduced, by an estimation that is upwards of
37%.

Benefits
    We are unable to monetize benefits. We can find no casualties that
would have been prevented by these regulations. However, third-party
testing and certification for critical equipment, such as electrical
equipment intended for use in hazardous locations, addresses a
potentially catastrophic hazard consisting of an explosive gas or vapor
combined with an electrical ignition source, and is generally
understood by industry as an appropriate measure that enhances safety
and protects life, the environment, and property.
Alternatives
    We considered five alternatives when evaluating the effects of this
final rule. The first, abstaining from action, was rejected because it
allows a regulatory imbalance and a potential safety gap to exist
between foreign vessels and U.S. vessels operating on the OCS.
    The second alternative we considered was to require both U.S. and
foreign vessels and facilities to adhere to the existing international
standards. This alternative was deemed insufficient because compliance
with international standards, such as the 2009 IMO Code, is subject to
the interpretation of the applicable flag administration. An example of
an undesired consequence of this alternative would be the acceptance of
ATEX certified equipment. The Coast Guard, however, will not accept
ATEX certifications because evidence of full testing to the applicable
harmonized 60079 series of standards by an independent third-party
laboratory is not guaranteed. Consistent with preexisting Coast Guard
practices, third-party testing and certification for critical equipment
is generally required.
    The third alternative we considered was to require foreign vessels
and floating facilities to meet current U.S. standards. This
alternative was not selected because we believe that requiring
compliance with U.S. standards is unnecessary when there are comparable
international standards acceptable to the Coast Guard. Because these
latest editions of internationally recognized standards for explosion
protection offer owners and operators greater flexibility, while also
avoiding the costs of coastal state-specific requirements, we are
expanding the list of international explosion protection standards
deemed acceptable.
    The fourth alternative, implementing the regulations in this final
rule, puts in place a regulatory regime that will allow for both the
U.S., as the coastal state, and industry to be confident in the
certification and assessment of electrical equipment intended for use
in hazardous locations. This will be achieved through the use of the
most current, internationally recognized standards for explosion
protection and independent third-party certification. The regulations
in this final rule expand the list of national and international
explosion protection standards deemed acceptable for U.S. operators.
    A fifth and final alternative is that which was presented to the
public in the NPRM. This alternative included the application of the
NPRM regulations to existing vessels before those vessels engaged in
OCS activities for the first

time. This alternative would have included foreign vessels currently
under contract or construction. We determined that this alternative
would force an undue burden on the industry due primarily to the cost
effects. Industry's comments to the docket suggest that the compliance
cost per vessel could be cost prohibitive. With current estimates of
219 foreign MODUs in some stage of construction, the cost of this
alternative could have potentially outpaced its benefits.

B. Small Entities

    Under the Regulatory Flexibility Act, 5 U.S.C. 601-612, we have
considered whether this rule will have a significant economic impact on
a substantial number of small entities. The term ``small entities''
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.
    We do not anticipate any effect on small entities. As noted in the
previous discussion, there is no anticipated cost burden placed on U.S.
entities by this rule and, as such, we do not anticipate any effect on
small entities that would be addressed by this section. Therefore, the
Coast Guard certifies under 5 U.S.C. 605(b) that this rule will not
have a significant economic impact on a substantial number of small
entities.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996, Public Law 104-121, we offered to assist small
entities in understanding this rule so that they could better evaluate
its effects on them and participate in the rulemaking. The Coast Guard
will not retaliate against small entities that question or complain
about this 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 rule calls for no new collection of information under the
Paperwork Reduction Act of 1995, 44 U.S.C. 3501-3520.

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 rule under that Order and have
determined that it is consistent with the fundamental principles and
preemption requirements described in Executive Order 13132. Our
analysis is explained below.
    It is well settled that States may not regulate in categories
reserved for exclusive regulation by the Coast Guard. It is also well
settled that all of the categories for inspected vessels covered in 46
U.S.C. 3306, 3703, 7101, and 8101 (design, construction, alteration,
repair, maintenance, operation, equipping, personnel qualification, and
manning of vessels), as well as the reporting of casualties and any
other category in which Congress intended the Coast Guard to be the
sole source of a vessel's obligations, are within fields foreclosed
from regulation by the States. (See the decision of the Supreme Court
in the consolidated cases of United States v. Locke and Intertanko v.
Locke, 529 U.S. 89, 120 S.Ct. 1135 (March 6, 2000).) This final rule
regulates electrical equipment standards on inspected vessels. As such,
States may not regulate within this category. Therefore, the rule is
consistent with the principles of federalism and preemption
requirements in Executive Order 13132.

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. Though this rule will not result in
such an expenditure, we do discuss the effects of this rule elsewhere
in this preamble.

G. Taking of Private Property

    This rule will not cause a taking of private property or otherwise
have taking implications under E.O. 12630 (``Governmental Actions and
Interference with Constitutionally Protected Property Rights'').

H. Civil Justice Reform

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

I. Protection of Children

    We have analyzed this rule under E.O. 13045 (``Protection of
Children from Environmental Health Risks and Safety Risks''). This 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 rule does not have tribal implications under E.O. 13175
(``Consultation and Coordination with Indian Tribal Governments''),
because it would not have a substantial direct effect on one or more
Indian tribes, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes.

K. Energy Effects

    We have analyzed this rule under E.O. 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 E.O. 12866 and is not likely to have a significant
adverse effect on the supply, distribution, or use of energy.

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 (e.g.,
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 rule uses the following voluntary consensus standards:

M. Environment

    We have analyzed this final rule under Department of Homeland
Security Management Directive 023-01 and Commandant Instruction
M16475.lD, which guide the Coast Guard in complying with the National
Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and
have concluded that this action is one of a category of actions that do
not individually or cumulatively have a significant effect on the human
environment. This final rule is categorically excluded under section
2.B.2, figure 2-1, paragraphs (34)(a), (d) and (e) of the Instruction
and under section 6(a) of the ``Appendix to National Environmental
Policy Act: Coast Guard Procedures for Categorical Exclusions, Notice
of Final Agency Policy'' (67 FR 48244, July 23, 2002).'' This final
rule involves regulations which are editorial and concern inspection
and equipping of vessels and regulations concerning vessel operation
safety standards. An environmental analysis checklist and a categorical
exclusion determination are available in

the docket where indicated under ADDRESSES.
