[Docket No. USCG-2012-0850]
RIN 1625-AC00

Electrical Equipment in Hazardous Locations

AGENCY: Coast Guard, DHS.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: The Coast Guard proposes to amend its regulations. This 
proposed subpart would be applicable to foreign Mobile Offshore 
Drilling Units (MODUs), floating facilities, and vessels that engage in 
OCS activities for the first time after the effective date of the 
regulations. The proposed subpart would also be applicable to newly 
constructed U.S. MODUs, floating facilities, and vessels, excluding 
offshore supply vessels (OSVs). The proposed regulations would expand 
the list of national and international explosion protection standards 
deemed acceptable, as well as add the internationally accepted 
independent third-party certification system, the IEC System for 
Certification to Standards relating to Equipment for use in Explosive 
Atmospheres, as an accepted method of testing and certifying electrical 
equipment intended for use in hazardous locations. The proposed 
regulations would also provide owners and operators of existing U.S. 
MODUs, floating OCS facilities, and vessels, other than OSVs, that 
engage in OCS activities and U.S. tank vessels that carry flammable or 
combustible cargoes the option of choosing between the compliance 
regime contained in existing regulations. This proposal would support 
the U.S. Coast Guard's maritime safety mission.

III. Background

    On September 9, 2011, the Coast Guard published the final action 
memo (FAM) by the Commandant on the recommendations of its 
investigation into the explosion, fire, and sinking of the Mobile 
Offshore Drilling Unit (MODU) DEEPWATER HORIZON and the resulting loss 
of 11 of its crew members. One key finding of the Coast Guard's 
investigation of the DEEPWATER HORIZON emphasized the importance of 
proper electrical equipment installations in hazardous locations during 
oil drilling exploration on U.S. and foreign MODUs. The ignition or 
explosion hazards posed by electrical equipment installations during 
Outer Continental Shelf (OCS) activities involving storage, production 
and processing of hydrocarbons were also considered in the report. You 
may view a copy of the FAM and the investigation online by going to the 
Coast Guard's Web site at http://uscg.mil/hq/cg5/cg545 and clicking on 
the Deepwater Horizon-exhibits-transcripts-video link. The Coast Guard, 
therefore, reviewed the existing regulations for hazardous locations, 
specifically the requirements for electrical equipment testing and 
certification as well as the referenced 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 in 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. While 
foreign floating OCS facilities must meet the same engineering 
standards as U.S. floating OCS facilities, foreign vessels generally 
meet the standards of their flag administration. Their compliance with 
international standards, such as the IMO MODU Code, is subject to the 
interpretation of the applicable flag administration. With respect to 
explosion protection standards, this can result in the installation of 
equipment on vessels that has not been tested by an independent third-
party laboratory. The Coast Guard believes that U.S. and foreign 
vessels and floating facilities that engage in OCS activities for the 
first time, after the effective date of the regulations, should have 
equivalent standards. The Coast Guard, therefore, proposes to require 
third-party testing and certification of electrical equipment in 
hazardous locations in order to achieve an equivalency of standards 
between U.S. and foreign vessels and floating facilities.
    The Coast Guard identified an international certification system 
that requires full testing to the IEC 60079 series of explosion 
protection standards. The IECEx System pertains to ``Certification to 
Standards Relating to Equipment for Use in Explosive Atmospheres'' 
which requires full testing to the applicable IEC 60079 standard by an 
explosive atmospheres (Ex) Testing Laboratory (ExTL) and issuance of 
certification (Certificate of Conformity) by an Ex Certification Body 
(ExCB). The ExTL and ExCB are accepted under the IECEx system after 
meeting the competency requirements established by the International 
Organization for Standardization (ISO)/IEC Standard 17025 and related 
IECEx Operational Documents and Rules of Procedure. Some foreign flag 
administrations do not impose the IEC 60079 series of standards, and 
instead accept an ``EC Type Examination Certificate'' issued under the 
European Commission Directive (94/9/EC) on Equipment and Protective 
Systems Intended for use in Potentially Explosive Atmospheres (ATEX 
Directive) for EU member nations. In contrast to IECEx, certification 
under the ATEX Directive show compliance with the Essential Health and 
Safety Requirements of the ATEX directive for which full or partial 
compliance with an IEC harmonized standard, may be used, but it does 
not specifically require full testing and certification by an 
independent third party laboratory. Accordingly, to adequately address 
the DEEPWATER HORIZON report's recommendations identified above, the 
Coast Guard proposes to amend the hazardous locations regulations to 
include the IECEx System. Additionally, the Coast Guard proposes to 
expand the list of national and international explosion protection 
standards deemed acceptable.

IV. Discussion of Proposed Rule

    The Coast Guard proposes to add a new subpart, 46 CFR subpart 
111.108, that would require foreign MODUs, floating OCS facilities, and 
vessels that engage in OCS activities for the first time after the 
effective date of the regulations, to have a level of safety equivalent 
to the certification regime required under subpart 111.105. Currently, 
these vessels and floating OCS facilities must comply with 33 CFR 
subchapter N. We propose to amend 33

[[Page 37762]]

CFR 143.120, add 143.208, and add 143.302 to require newly built 
foreign vessels and floating OCS facilities and existing foreign 
vessels and floating facilities that have never operated on the OCS to 
meet the proposed subpart 46 CFR 111.108.
    Foreign vessels and floating facilities operating on the OCS at the 
time of the effective date of the final rule will not be required to 
meet the requirements of this proposed rule because they are already 
subject to the existing applicable international standards and have 
been inspected by the Coast Guard in accordance with 33 CFR subchapter 
N. Through its existing inspection authorities, the Coast Guard is 
examining electrical installations in hazardous locations on these 
vessels and floating OCS facilities to ensure they meet the appropriate 
standards. While this existing compliance scheme is workable, it is 
less than ideal as it leads to a patchwork of different standards 
across the OCS, which makes inspection by port state control officers 
and compliance by owners and operators more difficult because it 
requires familiarity with multiple standards and certification schemes. 
The Coast Guard has determined that the benefit of a consistently 
applied standard is preferable and its requirements can be followed at 
little to no cost (see discussion of costs below).
    This proposed subpart would also apply to newly constructed U.S. 
MODUs, floating facilities, and vessels, excluding offshore supply 
vessels (OSVs) \1\. Additionally, this proposed rule would provide 
owners and operators of existing U.S. MODUs, floating OCS facilities, 
and vessels, other than OSVs, that engage in OCS activities and U.S. 
tank vessels that carry flammable or combustible cargoes the option of 
choosing between the compliance regime contained in existing subpart 
111.105 or the one in proposed subpart 111.108. Note, this proposed 
rule would not affect any existing domestic-flagged vessels or 
facilities that have not already operated on the OCS as they comply 
with subpart 111.105.
---------------------------------------------------------------------------

    \1\ These proposed regulations would not apply to U.S. OSVs 
although those vessels may be the subject of a separate, future 
rulemaking. Currently, U.S. OSVs must meet the hazardous location 
requirements of 46 CFR subchapter L.
---------------------------------------------------------------------------

    This proposed rule would allow the use of the latest editions of 
the North American Nationally Recognized Testing Laboratory (NRTL) 
standards, the American National Standards Institute/International 
Society of Automation (ANSI/ISA) 60079 series of standards referenced 
in Article 505 of the National Electrical Code (NEC), and the 
international consensus standards, International Electrotechnical 
Commission (IEC) 60079 Series. Further, the proposed regulations would 
permit the use of an internationally accepted certification system, the 
IECEx System.
    The term ``hazardous location'' is broadly understood as a location 
where concentrations of flammable gases, vapors, or dusts (commonly 
referred to as explosive atmospheres) occur or may be present. 
Electrical equipment in these locations are specifically designed, 
tested, certified, or listed, and installed to ensure that explosions 
due to equipment arcing or high surface temperature do not occur. 
Hazardous locations may be classified by Class/Division or by Zone; 
thus the definitions of these terms would be included in the proposed 
revisions to Sec.  110.15-1.
    The Coast Guard proposes to add provisions specific to U.S. and 
foreign MODUs, floating OCS facilities, vessels (excluding U.S. OSVs) 
engaged in OCS activities, and U.S. tank vessels that carry flammable 
and combustible cargoes. These provisions would prescribe the use of 
the latest editions of widely accepted NRTL or international consensus 
standards.
    With respect to U.S. industry standards, these proposed regulations 
would allow U.S. and foreign MODUs, floating OCS facilities, vessels 
(excluding U.S. OSVs) engaged in OCS activities, and existing U.S. 
MODUs, floating OCS facilities, and vessels, other than OSVs, that 
engage in OCS activities and U.S. tank vessels carrying flammable and 
combustible cargoes to comply with either of two hazardous locations 
classification systems found in the NEC, also known as National Fire 
Protection Association 70 (NFPA 70). Both of these systems classify 
hazardous locations according to the likely presence of explosive 
atmospheres. Hazardous locations may comply with Articles 500 through 
504 of NFPA 70, expressed in Class and Divisions, or may comply with 
Article 505 of NFPA 70, expressed in Class and Zones. Articles 501 and 
505 provide guidance in combining listed or certified equipment for use 
in Division or Zone hazardous locations. In order to delineate areas 
within a Class I, Division 1 location where explosive atmospheres are 
always present (i.e., equivalent to Zone 0 in Article 505 of NFPA 70), 
the Coast Guard decided to use the term ``Class I, Special Division 
1.'' This term is based on the American Petroleum Institute Recommended 
Practice (API RP) 500. Regardless of which Article of NFPA 70 is 
followed, the proposed regulations in Sec.  111.108-3(b)(1) and (b)(2) 
would require the equipment to be tested and listed or certified by a 
Coast Guard-accepted independent laboratory. A list of Coast Guard-
accepted independent laboratories can be found at http://cgmix.uscg.mil/.
    As an alternative to the North American NRTL standards, the 
proposed regulations for hazardous locations would allow U.S. and 
foreign MODUs, floating OCS facilities and vessels engaged in OCS 
activities, existing U.S. MODUs, floating OCS facilities, and vessels, 
other than OSVs, that engage in OCS activities, and U.S. tank vessels 
carrying flammable and combustible cargoes to comply with the widely 
accepted international standards IEC 61892-7 or IEC 60092-502. 
Consistent with the North American NRTL standards, the proposed 
regulations in Sec.  111.108-3(b)(3) would require electrical equipment 
to be tested and approved or certified by a Coast Guard-accepted 
independent laboratory in order to meet the provisions of Clause 6 of 
IEC 61892-7 or Clause 6 of IEC 600092-502, as applicable.
    The Coast Guard believes it is a vitally important and appropriate 
safety measure for the testing laboratory and certification body to 
follow published procedures established under an international 
certification scheme and conformity assessment system when performing 
the various testing and certification of electrical equipment for use 
in hazardous locations. Under the existing international regulatory 
standards governing foreign vessels and floating facilities engaged in 
OCS activities, however, equipment could be installed in hazardous 
locations that meets the IEC 60079 explosion protection standards but 
has not been tested and certified by an independent body. For this 
reason, the Coast Guard, through this NPRM, proposes to adopt the 
international certification system, the IECEx System, which implements 
the IEC 60079 series of standards. Additionally, the proposed 
regulations would add a new paragraph (q) in Sec.  110.25-1, ``Plans 
and information required for new construction,'' which would specify 
submittal of IECEx certification.
    The IECEx System is an internationally accepted certification 
system, widely used throughout the industry, that ensures electrical 
equipment is manufactured, tested, marked, installed, and certified for 
full compliance with the applicable IEC 60079 standards by a competent 
authority. Approval under the IECEx System involves an Ex Certification 
Body (ExCB) and an Ex Testing Laboratory (ExTL) that have been

[[Page 37763]]

accepted into the IECEx System after meeting competence requirements 
found in the International Organization for Standardization ISO/IEC 
Standard 17025 and related IECEx procedures. The ExTL tests the subject 
equipment and drafts an Ex Test Report (ExTR) to document the test 
results. The ExCB reviews the manufacturing quality assurance process 
and issues an IECEx Quality Assessment Report (QAR). Based on the QAR 
and ExTR, the ExCB issues an IECEx Certification of Conformity for the 
equipment.
    For protections not covered by the standards discussed above, this 
proposed rule would incorporate existing requirements for other large 
vessels. For example, proposed Sec.  111.108-3 contains submerged pump 
motor requirements based on existing Subpart 111.105 and tank barge 
regulations. It also incorporates ASTM International (ASTM) F2876-10, 
``Standard Practice for Thermal Rating and Installation of Internal 
Combustion Engine Packages for Use in Hazardous Locations in Marine 
Applications,'' to address the growing use of engines with electronic 
controls that could cause arcing or sparking in hazardous locations.

V. Incorporation by Reference

    Material proposed for incorporation by reference appears in 46 CFR 
110.10. You may inspect this material at U.S. Coast Guard Headquarters 
where indicated under ADDRESSES. Copies of the material are available 
from the sources listed in Sec.  110.10-1.
    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. Below we summarize our 
analyses based on these statutes or executive orders.

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. Two additional executive orders were recently 
published to promote the goals of Executive Order 13563: Executive 
Orders 13609 (``Promoting International Regulatory Cooperation'') and 
13610 (``Indentifying and Reducing Regulatory Burdens''). Executive 
Order 13609 targets international regulatory cooperation to reduce, 
eliminate, or prevent unnecessary differences in regulatory 
requirements. Executive Order 13610 aims to modernize the regulatory 
systems and to reduce unjustified regulatory burdens and costs on the 
public.
    This proposed rule is not a significant regulatory action under 
section 3(f) of Executive Order 12866, Regulatory Planning and Review, 
as supplemented by Executive Order 13563, Improving Regulation and 
Regulatory Review, 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 
proposed rule to ascertain its probable impacts on industry. We 
consider all estimates and analysis in this Regulatory Analysis to be 
draft and subject to change in consideration of public comments.
    A summary of the draft Regulatory Assessment follows:

U.S. Vessels
    We do not anticipate any costs to be borne by the U.S.-flagged 
vessels that would be affected by this proposed rule. The proposed rule 
would require that all U.S. vessels, excluding OSVs, comply with the 
newly created subpart 111.108. Our analysis is simplified due to the 
population demographics, which are filtered to include only those 
vessels which would (a) be on the OCS in pursuit of OCS activities as 
defined by this proposed rule, and (b) contain a hazardous area. 
Evaluation of vessel population data maintained by the Coast Guard and 
contained in the Marine Information for Safety and Law Enforcement 
(MISLE) database allows us to determine a potential 297 vessels that 
would fall under the umbrella of this proposed rule. All of these 
vessels are of the oil recovery type.
    Proposed subpart 111.108 would not impose any burden on U.S. 
vessels due to the nature of the standards being incorporated. For 
example, existing subpart 111.105 refers to Articles 500-505 of the NEC 
(2002) while proposed subpart 111.108 would refer to NEC (2011) 
Articles 500-505. Because North American certification of electrical 
equipment is generally to the most current edition of the published 
reference standards,\9\ 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. The 
Coast Guard strives to incorporate updated standards after publication 
by the standards development organizations. During the time between the 
publication date of the updated standard and the date it is 
incorporated into Coast Guard regulations, certifying laboratories 
evaluate new equipment using the updated standard. Because all of the 
vessels affected by this proposed rule would be newly built and the 
equipment will be certified before being installed on these vessels, 
all vessels affected by this proposed rule would be required to be in 
compliance with the updated standards proposed in subpart 111.108.
---------------------------------------------------------------------------

    \9\ Confirmed by Principal Engineer--Global Hazardous Locations 
Product Safety, UL LLC., 12/26/2012
---------------------------------------------------------------------------

    The logic applied to U.S. vessels, excluding OSVs, applies to U.S. 
MODUs and floating OCS facilities as well. We do not anticipate any 
cost burden associated with this proposed rule to be imposed on this 
vessel class. We believe this because the affected population is 
entirely found under the `new build' designation. As discussed earlier, 
these new builds would be required to comply with proposed subpart 
111.108, a subpart that contains the updated standards to which new 
equipment would be certified. As with the vessels discussed earlier, in 
the absence of proposed subpart 111.108, new equipment would be built 
to the most current standards as a matter of industry practice. Over 
the 10-year period during which the population data for this vessel 
class was compiled, 24 new MODUs were built and a single U.S. MODU 
entered the OCS from a foreign location. Under the proposed rule, this 
scenario would not require any costs to the vessel owner as there is no 
change in the regulatory environment for these existing vessels.
    The proposed rule contains language pertinent to existing U.S. 
MODUs, floating OCS facilities, and vessels, other than OSVs, that 
engage in OCS activities, and U.S. tank vessels, but we do not foresee 
any associated costs to the owners of these vessels and facilities. 
Currently, the regulations for electrical installations in hazardous 
locations are contained in subpart 111.105. The proposed regulation 
will expand the available subparts to include proposed subpart 111.108, 
while still allowing owners and operators, the option to remain subject 
to existing subpart 111.105.
Foreign Vessels
    Currently, foreign vessels are required to comply with the 
regulations governing electrical installations in hazardous locations 
of the nation under whose flag they operate. This proposed rule would 
require foreign vessels new to the OCS to comply with proposed subpart 
111.108. Our analysis is simplified due to the population that the 
proposed regulation is expected to affect. Based on historical 
information found in the Ship Arrival Notification System (SANS) \10\ 
database, we are able to ascertain the number of foreign vessels that 
have engaged in OCS activities. After filtering this population data 
for vessels with prior visits to the OCS, we anticipate the affected 
foreign vessel population that is new to the OCS to be zero. 
Additionally, there were no new arrivals on the OCS by foreign vessels 
built within the ten year period, 2002-2011, that would be affected by 
the proposed rule. It is for these reasons that there is no anticipated 
cost burden on vessels within this class. Foreign MODUs, however, 
require special consideration, which is provided in the following 
section.
---------------------------------------------------------------------------

    \10\ This database is maintained by the Coast Guard and contains 
a record of vessel arrival and departure data.
---------------------------------------------------------------------------

    Currently, foreign MODUs & floating facilities that engage in OCS 
activities are subject to the regulatory schemes accepted by the nation 
under whose flag they operate. Equipment certified and accepted by a 
flag administration may or may not include evaluation by an accepted 
third-party laboratory. The Coast Guard seeks to address this potential 
safety gap by requiring that electrical installations on foreign

[[Page 37765]]

MODUs & floating facilities conform to the required third-party 
certification processes accepted under proposed subpart 111.108. Those 
foreign MODUs & floating facilities that have engaged in documented OCS 
activities prior to implementation of the proposed rule would be exempt 
from proposed subpart 111.108, which would allow them to continue to 
operate without changes. The foreign MODUs & floating facilities that 
will be affected by this proposed rule are those vessels that are new 
to the OCS. Over a 10-year period between 2002 and 2011, 16 foreign-
flagged MODUs & floating facilities that would be affected by this 
proposed rule have entered the OCS. This equates to an average yearly 
rate of 1.6 \11\ vessels seeking entrance into U.S. waters in pursuit 
of engaging in OCS activities. We assume that this rate will stay 
constant into the future.
---------------------------------------------------------------------------

    \11\ 16 vessels & facilities/10 years = 1.6 vessels & facilities 
per year on average.
---------------------------------------------------------------------------

    Vessels that seek to engage in OCS activities for the first time 
that are not in compliance with the proposed rules have two options. 
The vessel owners can either replace the electrical equipment with 
equipment certified under a permissible scheme or seek recertification 
from a Coast Guard-approved third-party laboratory. As a conservative 
estimate, we constructed calculations for full replacement or 
recertification of all electrical equipment in hazardous areas present 
on the vessel, as the potential for partial replacement or 
recertification of non-conforming equipment will be determined on a 
vessel specific basis.
    We constructed cost estimates for both of these options after 
discussion with experts. We estimate that it would cost a vessel owner 
$500,000 \12\ per vessel for full replacement of electrical equipment 
in hazardous areas. The second option, recertification of the equipment 
covered by this proposed rule, may be lower in cost. Additionally, it 
may be the preferred option for some vessel owners looking to comply 
with the regulation proposed in this NPRM. For the purposes of our 
analysis, pertaining to the recertification option, significant 
information gaps exist regarding its implementation. A discussion of 
the shortcomings of said data follows.
---------------------------------------------------------------------------

    \12\ Estimate provided by Regulatory Advisor--MWCS, Exxon Mobil, 
8/14/2012.
---------------------------------------------------------------------------

    Recertification of equipment would begin with evaluation of 
existing laboratory documentation, if available, to ascertain the gap 
between what is acceptable to an ATEX certifying laboratory and what is 
acceptable to an IECEx certifying laboratory, for example. After the 
initial evaluation is completed, the next step would be a decision 
regarding acceptance, recertification, or replacement of the equipment. 
The cost estimate provided includes in-office labor for the initial 
evaluation, travel and labor time to complete a physical inspection, 
and final evaluation and document preparation by the certifying 
laboratory.
    The cost for recertification on a MODU is estimated to begin at 
$35,000.\13\ The estimated cost range for a given vessel to comply with 
the proposed regulation is between $35,000 to $500,000, depending on 
the composition and the extent of equipment replacement. The myriad 
types of MODUs and facilities operating on the OCS may contain a 
diverse range of equipment, with some equipment requiring replacement 
in order to comply with the proposed rulemaking, while other equipment 
may be able to be recertified after evaluation by a certified 
laboratory. A vessel found to have all equipment in compliance with the 
proposed regulation could conceivably proceed with recertification, for 
an estimated $35,000. However, because vessel specific information is 
unavailable, we estimate the cost of the proposed rulemaking 
conservatively at $500,000 per vessel, which reflects the cost 
associated with full replacement of electrical equipment on a vessel. 
At an entry rate of 1.6 per year and a cost of $500,000 per vessel & 
facility, the yearly cost for compliance for the industry is projected 
to be $800,000, as presented in Table 2.

Benefits
    The Coast Guard is unable to monetize benefits. We can find no 
casualties that would have been prevented with recertification. 
However, the importance of 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/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 four alternatives when evaluating the effects of this 
proposed rule. The first, abstaining from action, was deemed to leave a 
significant hazard not addressed. Further, it allows a regulatory 
imbalance to exist because foreign vessels and facilities operating on 
the OCS would not be required to meet the same standards for explosion

[[Page 37766]]

protection and independent third-party certification as those of U.S. 
vessels and facilities operating in the same service.
    The second alternative we considered was to require both U.S. and 
foreign-flagged vessels and facilities to adhere to the existing 
international standards. This alternative was deemed insufficient 
because compliance with international standards, such as the 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 specific, 
comparable international standards acceptable to the Coast Guard. 
Because these latest editions of internationally recognized standards 
for explosion protection and independent third-party certification 
offer owners and operators greater flexibility while also avoiding the 
costs of coastal state specific requirements, the Coast Guard proposes 
to expand the list of international explosion protection standards 
deemed acceptable.
    The final alternative, implementing the proposed regulation, would 
put in place a regulatory regime that would 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 would be achieved through the use of the most current, 
internationally recognized standards for explosion protection and 
independent third-party certification. Lastly, the proposed regulation 
would expand the list of national and international explosion 
protection standards deemed acceptable for U.S. operators.

B. Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have 
considered whether this proposed rule would 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 proposed 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 proposed rule, if promulgated, will 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 the Docket Management 
Facility at the address under ADDRESSES. In your comment, explain why 
you think it qualifies and how and to what degree this rule would 
economically affect it.

C. Assistance for Small Entities

    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 does not increase the burden under a current a 
collection of information under the Paperwork Reduction Act of 1995 (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. The title and description of the 
information collections, a description of those who must collect the 
information, and an estimate of the total annual burden follow. The 
estimate covers the time for reviewing instructions, searching existing 
sources of data, gathering and maintaining the data needed, and 
completing and reviewing the collection.
    Title: Plan Approval and Records for Electrical Engineering 
Regulations--Title 46 CFR Subchapter J.
    OMB Control Number: 1625-0031.
    Summary of the Collection of Information: The information sought 
here is needed to ensure compliance with our rules on electrical 
engineering for the design and construction of U.S.-flag commercial 
vessels.
    Need For Information: These regulations contain the primary 
standards for the review of electrical installations on all new U.S. 
Coast Guard certificated vessels except small passenger vessels. Recent 
amendments to the regulations clarify the regulations, bring them up to 
date, and delete unnecessary requirements. The revisions to Subchapter 
J reduced the reliance on domestic standards and adopted SOLAS and 
other international standards developed through consensus by the 
international maritime community. The information collection 
requirements described in this supporting statement are necessary to 
implement the regulations in 46 CFR Parts 110 through 113.
    The Coast Guard requires industry complete electrical engineering 
plans to meet performance requirements on new-built vessels. These 
requirements help resolve much of the confusion during inspections that 
has risen due to the varying special missions of modern merchant 
vessels.
    The collection of information is needed to demonstrate that certain 
specific regulations implement the international requirements. The 
requirements generally reflect routine practices for U.S. merchant 
companies.
    Proposed Use of Information: The purpose of the information 
collection is to ensure compliance with electrical safety regulations. 
Through the review of the plans prior to construction, the vessel owner 
of builder may be assured that the vessel, if built in accordance with 
the plans, will meet regulatory standards.
    Description of the Respondents: Owners, operators, and builders of 
vessels.
    Number of Respondents: 186.
    Frequency of Response: On occasion.
    Burden of Response: Hour Burden: 4,754 hours. Cost burden: 
$399,336.
    Estimate of Total Annual Burden: The estimated annual hour burden 
is 4,754 hours. The estimated annual cost burden is $399,336.
    As required by the Paperwork Reduction Act of 1995 (44 U.S.C. 
3507(d)), we will submit a copy of this proposed rule to the Office of 
Management and Budget (OMB) for its review of the collection of 
information.
    We ask for public comment on the proposed collection of information 
to help us determine how useful the information is; whether it can help 
us

[[Page 37767]]

perform our functions better; whether it is readily available 
elsewhere; how accurate our estimate of the burden of collection is; 
how valid our methods for determining burden are; how we can improve 
the quality, usefulness, and clarity of the information; and how we can 
minimize the burden of collection.
    If you submit comments on the collection of information, submit 
them both to OMB and to the Docket Management Facility where indicated 
under ADDRESSES, by the date under DATES.
    You need not respond to a collection of information unless it 
displays a currently valid control number from OMB. Before the Coast 
Guard could enforce the collection of information requirements in this 
proposed rule, OMB would need to approve the Coast Guard's request to 
collect this information.

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 does not have implications for federalism.
    It is well settled that States may not regulate in categories 
reserved for regulation by the Coast Guard. It is also well settled, 
now, that all of the categories 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 the field 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 rule addresses the design, 
construction, alteration, repair, maintenance, operation, and 
equipping, of vessels and facilities engaged in OCS activities. Because 
the States may not regulate within these categories, preemption under 
Executive Order 13132 is not an issue.

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 proposed rule would not 
result in such an expenditure, we do discuss the effects of this 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 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 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. This proposed rule is not a 
``significant regulatory action'' under Executive Order 12866, and it 
is not likely to have a significant adverse effect on the supply, 
distribution, or use of energy. The Administrator of the Office of 
Information and Regulatory Affairs has not designated it as a 
significant energy action. Therefore, it does not require a Statement 
of Energy Effects under Executive Order 13211.

L. Technical Standards

    The National Technology Transfer and Advancement Act (15 U.S.C. 272 
note) directs agencies to use voluntary consensus standards in their 
regulatory activities unless the agency provides Congress, through the 
Office of Management and Budget, 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 proposed rule uses the following voluntary consensus 
standards:

M. Environment

    We have analyzed this proposed 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 
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 environmental analysis 
checklist supporting this determination is available in the docket 
where indicated under the ``Public Participation and Request for 
Comments'' section of this preamble. This proposed rule is likely to be 
categorically excluded under section 2.B.2, figure 2-1, paragraphs 
(34)(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 
48243, July 23, 2002). This rule involves regulations concerning 
inspection and equipping of vessels; regulations concerning equipment 
approval and carriage requirements; and regulations concerning vessel 
operation safety standards. We seek any comments or information that 
may lead to the discovery of a significant environmental impact from 
this proposed rule.
