[Docket No. USCG-2012-0975]
RIN 1625-AB96

Double Hull Tanker Escorts on the Waters of Prince William Sound, 
Alaska

AGENCY: Coast Guard, DHS.

ACTION: Interim rule with request for comments.

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

SUMMARY: The Coast Guard is amending the escort requirements for 
certain tankers operating on the waters of Prince William Sound, Alaska 
(PWS). This interim rule is necessary to implement section 711 of the 
Coast Guard Authorization Act of 2010 (Act), which mandates two tug 
escorts for double hull tankers over 5,000 gross tons transporting oil 
in bulk in PWS. The Act directed the Coast Guard to promulgate interim 
regulations as soon and practicable to ensure that tug escort 
requirements apply to certain double hull tankers.

DATES: This interim rule is effective September 18, 2013. Comments and 
related material must either be submitted to our online docket via 
http:

III. Regulatory History

    The Coast Guard is issuing this interim rule without prior notice 
and opportunity to comment pursuant to section 711 of the Coast Guard 
Authorization Act of 2010 (Pub. L. 111-281, 124 Stat. 2905)(Act) that 
mandates the requirements in this rule. The Act requires that interim 
regulations be issued without notice and hearing pursuant to section 
553 of title 5 of the United States Code. Because of this congressional 
directive, publication of an NPRM is unnecessary.
    Although this interim rule will become effective 30 days after 
publication in the Federal Register, we are issuing this rule with a 
request for comments to solicit and consider information from those 
entities that may be impacted by this rule. See Section I.A. of this 
rule for information regarding the submission of comments.

[[Page 50337]]

IV. Basis and Purpose

    The basis of this rulemaking is section 711 of the Act. In section 
711, Congress directed the Coast Guard to revise its regulations to 
require all double hull tankers over 5,000 gross tons (GT) transporting 
oil in bulk in Prince William Sound, Alaska (PWS) to be escorted by at 
least two towing vessels or other vessels considered to be appropriate 
by the Secretary. This requirement is intended to increase the 
protection of the environment and the safety of vessels transiting PWS 
by reducing the risk of groundings, allisions or collisions when escort 
vessels are readily available to assist a tanker in distress.

Background

    Section 4116(c) of the Oil Pollution Act of 1990 (Pub. L. 101-380, 
104 Stat. 484)(OPA 90) required the two vessel escort system for single 
hull tank vessels over 5,000 GT transporting oil in bulk in PWS. These 
regulations are found in 33 CFR part 168. OPA 90 also mandated the 
phase-out of single hull tank vessels by January 1, 2015, and required 
that newly built tank vessels be double hulled.
    With the phase-out of the single hull tank vessels, there would be 
no requirement for any tank vessel to maintain an escort system. 
Section 711 of the Act extends the escort system requirement to double 
hull tank vessels over 5,000 GT transporting oil in bulk in PWS.
    A double hull provides a tank vessel with added protection from an 
oil spill as a result of a hull breach due to a grounding, allision or 
collision. While double hull tank vessels provide greater protection 
from oil spills over single hull tank vessels, with section 711 of the 
Act Congress further intended to increase the protection of the 
environment and the safety of vessels transiting PWS.

V. Discussion of the Interim Rule

    The purpose of the existing regulations in 33 CFR part 168, Escort 
Requirements for Certain Tankers, is to reduce the risk of oil spills 
from laden, single hull tankers over 5,000 GT by requiring that these 
tankers be escorted by at least two suitable escort vessels in 
applicable waters. The applicable waters are defined in Sec.  168.40.
    The requirement of two escort vessels has contributed to a 
reduction in spill incidents because the escort vessels are immediately 
available to influence the tanker's speed and course in the event of a 
steering or propulsion equipment failure, thereby reducing the 
possibility of a grounding, allision or collision. This interim rule 
amends part 168 so that it also applies to double hull tankers over 
5,000 GT transporting oil in PWS. This rule codifies established 
industry practice for escorting double hull tank vessels on transits in 
and out of PWS.
    This interim rule revises three sections of 33 CFR part 168. We 
revised Sec.  168.01 to make it clear that part 168 now addresses 
escort vessels for double hull tankers as well as single hull tankers. 
We added a definition of the term double hull tanker to Sec.  168.05. 
Finally, this rule amends Sec.  168.20 to extend the applicability of 
part 168 to include double hull tankers over 5,000 GT transporting oil 
in bulk in PWS. All other sections of part 168, including the escort 
vessel performance and operational requirements in Sec.  168.50, which 
includes prescribed transit speeds and other maneuvering parameters 
such as directional variances for escort vessels, remain unchanged. 
With these changes, the Coast Guard is implementing the escort vessel 
requirements of section 711 of the Act.
    We considered two alternatives (including the preferred 
alternative) in the development of this rule. The key factors that we 
evaluated in considering each alternative included: (1) The degree to 
which the alternative comported with the congressional mandate in 
section 711 of the Act; (2) what benefits, if any, would be derived, 
such as enhancement of personal and environmental safety and security; 
and (3) cost effectiveness. The alternatives considered are as follows:
    Alternative 1: Revise 33 CFR 168 to include double hull tankers 
over 5,000 GT transporting oil in bulk in PWS, but do not revise the 
existing performance-based escort requirements (preferred alternative). 
At present, two tug escorts of both single and double hull tankers is 
the industry practice being employed on the waters of PWS. 
Implementation of this interim rule will codify current industry 
practice.
    Alternative 2: Take no action. This option was not selected as it 
would not implement section 711 of the Act, which specifically requires 
the Coast Guard to issue regulations.
    We also considered adding a third escort vessel for double hull 
tank vessels that transit PWS. However, this would impose additional 
disproportionate costs on double hull tank vessel owners and operators 
(as single hull tank vessels would remain subject to the two escort 
requirement) without any incremental gain in benefits from the current 
industry practice of a dual vessel escort system (i.e., no casualties 
or other data indicating that two escort vessels were insufficient).
    Ultimately, we chose Alternative 1 as the preferred alternative to 
make revisions to 33 CFR part 168. Alternative 1 satisfactorily 
implements section 711 of the Act by adding two escort vessels for each 
double hull tanker transporting oil in bulk in PWS while also retaining 
the performance requirements in Sec.  168.50 that are readily 
applicable to tanker escorts regardless of whether the tanker is single 
or double hulled.

VI. Regulatory Analyses

    We developed this interim 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. This interim rule has not been designated a 
``significant regulatory action'' under section 3(f) of Executive Order 
12866. Accordingly, the interim rule has not been reviewed by the 
Office of Management and Budget. The Regulatory Assessment follows:
    This interim rule will require a two vessel escort system for 
double hull tankers over 5,000 GT transporting oil in bulk in PWS, as 
mandated by section 711(b) of the Act. Currently, single hull tankers 
are required to have two escort vessels per 33 CFR part 168. This 
interim rule will amend this part to extend this requirement to double 
hull tankers in PWS.
    Table 1 below summarizes the impacts of the interim rule.

                  Category                                                  Summary
----------------------------------------------------------------------------------------------------------------
Population..................................  --15 double-hull tank vessels that transit PWS annually.

                                              --Codification of current industry practice ensures benefits of
                                               dual vessel escort system in PWS remain, including reduction of
                                               the risk of an oil spill by influencing a vessel's speed and
                                               course in the event of equipment failure or loss of steering and/
                                               or propulsion.
----------------------------------------------------------------------------------------------------------------

Costs
    OPA 90 requires the two vessel escort system for single hull 
vessels over 5,000 GT transporting oil in bulk in PWS. However, single 
hull tankers are currently being phased out in favor of double hull 
tankers. Based on vessel traffic data from the Coast Guard Marine 
Safety Unit in Valdez, Alaska, no single hull vessels have called on 
PWS since 2009.
    Based on communications with the Marine Safety Unit in Valdez, AK, 
as well as the Vessel Traffic Service and Captain of the Port for that 
region, we determined that it has been an industry practice since 2008 
that double hull tankers be escorted by a two vessel escort system when 
in transit through PWS. Currently, 15 double hull tank vessels transit 
PWS and over the last 5 years, double hull tank vessels made an average 
of 250 port calls annually on PWS. One company operates the 12 tugs 
that participate in the two tug escort system in PWS.
    Since this interim rule will codify an industry practice that has 
been in place for over 5 years, we do not anticipate that this interim 
rule will impose additional costs on the public or industry, or alter 
industry behavior in any way. Finally, we do not anticipate that this 
interim rule will impose new costs on the Coast Guard or require the 
Coast Guard to expend additional resources.
Analysis of Alternatives
    We chose Alternative 1, which codifies current industry practice 
and implements section 711 of the Act as described above and in Section 
VI.B. below. We chose to reject Alternative 2, the ``no action'' 
alternative, because it would not implement section 711 of the Act.
Benefits
    This interim rule codifies the current industry practice of a dual 
vessel escort system in PWS. The primary benefit of the interim rule is 
eliminating confusion within industry by harmonizing the CFR with 
U.S.C. The practice of a dual vessel escort system also results in 
safety and environmental benefits, although these benefits exist under 
current practice. However, codification of the industry practice 
ensures the continuing benefits of the dual vessel escort system, which 
is to reduce the risk of an oil spill by ensuring the safe transit of 
tank vessels over 5,000 GT transporting oil in bulk in PWS. For PWS, we 
believe a two vessel escort system is beneficial in the event of 
equipment failure such as the loss of steering or propulsion. 
Additionally, if a tanker becomes disabled, the two escort vessels can 
influence the speed and course of the tanker, thereby reducing the 
likelihood of an allision, collision, or grounding. We reviewed 
allision, collision, and grounding casualty data for tank vessels in 
PWS over a 15-year period from 1998 through 2012 and found no casualty 
cases that involved a double hull tank vessel. All of these vessels 
were escorted by a two vessel escort.

B. Small Entities

    The Regulatory Flexibility Act of 1980 (RFA), 5 U.S.C. 601-612, as 
amended, requires federal agencies to consider the potential impact of 
regulations on small entities during rulemaking. However, when an 
agency is not required to publish an NPRM for a rule, the RFA does not 
require an agency to prepare a regulatory flexibility analysis. The 
Coast Guard was not required to publish an NPRM for this rule for the 
reasons stated in section III. ``Regulatory History'' and therefore is 
not required to publish a regulatory flexibility analysis.
    If you think that your business, organization, or governmental 
jurisdiction qualifies as a small entity and that this rule will 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

    Under section 213(a) of the Small Business Regulatory Enforcement 
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small 
entities in understanding this rule so that they can better evaluate 
its effects on them and participate in the rulemaking. If the rule 
would affect your small business, organization, or governmental 
jurisdiction and you have questions concerning its provisions or 
options for compliance, please consult Mr. Kevin Tone, CG-OES, Coast 
Guard; telephone 202-372-1441, email Kevin.P.Tone@uscg.mil. 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 federalism 
principles and preemption requirements described in Executive Order 
13132. Our analysis is explained below.
    As noted earlier in the preamble, this rule implements section 711 
of Public Law 118-281 for PWS. With respect to federalism, section 
711(c) of Public Law 118-281 provides that nothing in the

[[Page 50339]]

Act or any other provision of Federal law related to the regulation of 
maritime transportation of oil should be construed or interpreted as 
preempting the authority of the State, or a political subdivision 
thereof, from requiring escort vessels to accompany tankers 
transporting oil in bulk in PWS. Because this statute preserves the 
authority of the State of Alaska to promulgate additional requirements 
beyond that required by this rule in PWS, and because this rule merely 
implements the Congressional mandate, this rule does not have an effect 
on the relationship between the national government and the State of 
Alaska, and therefore is consistent with the fundamental federalism 
principles and preemption requirements described in Executive Order 
13132.
    Although this rule does not have an effect on the relationship 
between the national government and the State of Alaska, the Coast 
Guard recognizes the key role that State and local governments may have 
in making regulatory determinations. Additionally, for rules with 
implications and preemptive effect, Executive Order 13132 specifically 
directs agencies to consult with State and local governments during the 
rulemaking process.
    Therefore, the Coast Guard invites State and local governments and 
their representative national organizations to indicate their desire 
for participation and consultation in this rulemaking process by 
submitting comments to this interim rule. In accordance with Executive 
Order 13132, the Coast Guard will provide a federalism impact statement 
to document: (1) The extent of the Coast Guard's consultation with 
State and local officials who submit comments to this rule; (2) a 
summary of the nature of any concerns raised by State or local 
governments and the Coast Guard's position thereon; and (3) a statement 
of the extent to which the concerns of State and local officials have 
been met. We will also report to the Office of Management and Budget 
any written communications with the States.

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 Executive Order 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 Executive Order 12988, Civil Justice Reform, to minimize litigation, 
eliminate ambiguity, and reduce burden.

I. Protection of Children

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

J. Indian Tribal Governments

    This rule does not have tribal implications under Executive Order 
13175, Consultation and Coordination with Indian Tribal Governments, 
because it does 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 Executive Order 13211, Actions 
Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use. We have determined that it is not a ``significant 
energy action'' under that order because it is not a ``significant 
regulatory action'' under Executive Order 12866 and is not likely to 
have a significant adverse effect on the supply, distribution, or use 
of energy.

L. Technical Standards

    The National Technology Transfer and Advancement Act (NTTAA) (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 rule does not use technical standards. Therefore, we did not 
consider the use of voluntary consensus standards.

M. Environment

    We have analyzed this 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 rule is categorically excluded under section 6(b) 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 rule involves Congressionally-
mandated regulations designed to protect the environment, specifically, 
regulations implementing the requirements of the Act. An environmental 
analysis checklist and a categorical exclusion determination are 
available in the docket where indicated under ADDRESSES.
