33 CFR Part 147

[Docket No. USCG-2012-0024]
RIN 1625-AA00

Safety Zone; NOBLE DISCOVERER, Outer Continental Shelf Drillship,
Chukchi and/or Beaufort Seas, AK

AGENCY: Coast Guard, DHS.

ACTION: Temporary final rule.

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

SUMMARY: The Coast Guard is establishing a 500-meter safety zone in the
navigable waters, from the surface to seabed, around the DRILLSHIP
NOBLE DISCOVERER, while anchored or deploying and recovering moorings
on location in order to drill exploratory wells at various prospects
located in the Chukchi and/or Beaufort Seas Outer Continental Shelf,
Alaska, on or about July 1, 2012 through November 30, 2012. See TABLE
1. The purpose of the temporary safety zone is to protect the drillship
from vessels operating outside the normal shipping channels and
fairways. Placing a safety zone around the drillship will significantly
reduce the threat of allisions, which could result in oil spills, and
releases of natural gas, and thereby protect the safety of life,
property, and the environment. Lawful demonstrations may be conducted
outside of the safety zone.

DATES: The temporary safety zone becomes effective on July 1, 2012, and
terminates on December 1, 2012, unless sooner terminated by the
Commander, Seventeenth Coast Guard District.

SUPPLEMENTARY INFORMATION:

Regulatory Information

    On February 23, 2012 the Coast Guard published a notice of proposed
rulemaking (NPRM) entitled ``Safety Zone; NOBLE DISCOVERER, Outer
Continental Shelf Drillship, Chukchi and Beaufort Seas, Alaska'' in the
Federal Register (77 FR 10707). The NPRM included a 30-day comment
period. We received 3 (three) submissions with comments on the proposed
rule. No public meeting was requested, and none was held.
    Under 5 U.S.C. 553(d)(3), the Coast Guard finds that good cause
exists for making this rule effective less than 30 days after
publication in the Federal Register. The Coast Guard finds that good
cause exists for making this rule effective less than 30 days after
publication because to do otherwise would be contrary to the public
interest since immediate action is required to protect mariners,
vessels, and the environment from potential harm while the NOBLE
DISCOVERER is anchored or deploying and recovering moorings on
location.

Basis and Purpose

    The legal basis for the rule is 14 U.S.C. 85; 43 U.S.C. 1333;
Department of Homeland Security Delegation No. 0170.1. Collectively
they provide the authority for the Coast Guard to establish safety
zones on the Outer Continental Shelf.
    The Coast Guard is establishing a temporary safety zone in the
navigable waters, from the surface to seabed, around the DRILLSHIP
NOBLE DISCOVERER while anchored or deploying and recovering moorings on
location in order to drill exploratory wells in several prospects
located in the Chukchi and/or Beaufort Seas during the 2012 drilling
season.
    The request for the temporary safety zone was made by Shell
Exploration & Production Company due to safety concerns for both the
personnel aboard the NOBLE DISCOVERER and the environment. Shell
Exploration & Production Company indicated that it is highly likely
that any allision or inability to identify, monitor or mitigate any
risks or threats, including ice-related hazards that might be
encountered, could result in a catastrophic event. Incursions into the
safety zone by unapproved vessels could degrade the ability to monitor
and mitigate such risks. In evaluating this request, the Coast Guard
explored relevant safety factors and considered several criteria,
including but not limited to: (1) The level of shipping activity around
the operation; (2) safety concerns for personnel aboard the vessel; (3)
concerns for the environment given the sensitivity of the environmental
and subsistence importance to the indigenous population; (4) the lack
of any established shipping fairways, fueling and supply storage/
operations, and size of the crew increase the likelihood that an
allision could result in a catastrophic event; (5) the recent and
potential future maritime traffic in the vicinity of the areas; (6) the
types of vessels navigating in the vicinity of the area; (7) the
structural configuration of the vessel, and (8) the need to allow for
lawful demonstrations without endangering the safe operation of the
NOBLE DISCOVERER. For any group or individual intending to conduct
lawful demonstrations in the vicinity of the NOBLE DISCOVERER, these
demonstrations must be conducted outside the safety zone.
    Results from a thorough and comprehensive examination of the
criteria, IMO guidelines, and existing regulations warrant the
establishment of the temporary safety zone. The regulation will
significantly reduce the threat of allisions that could result in oil
spills, and releases. Furthermore, the regulation will increase the
safety of life, property, and the environment in the Chukchi and/or
Beaufort Seas by prohibiting entry into the zone unless specifically
authorized by the Commander, Seventeenth Coast Guard District, or a
designated representative. Due to the remote location and the need to
protect the environment, the Coast Guard may use criminal sanctions to
enforce the safety zone as appropriate.

    The temporary safety zone will be around the NOBLE DISCOVERER while
anchored or deploying and recovering moorings on location in order to
drill exploratory wells in various locations in the Chukchi and/or
Beaufort Seas Outer Continental Shelf, Alaska during the 2012
timeframe.
    Shell Exploration & Production Company has ten drill sites within
the Burger, Sivulliq and Torpedo prospects of the Chukchi and Beaufort
Seas, Alaska (See Table 1).

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

    During the 2012 timeframe, Shell Exploration & Production Company
has proposed drilling up to two exploration wells at the identified
Chukchi and Beaufort Sea prospects depending on favorable ice
conditions, weather, sea state, and any other pertinent factors. Each
of these drill sites will be permitted for drilling in 2012 to allow
for operational flexibility in the event sea ice conditions prevent
access to one of the locations. The number of actual wells that will be
drilled will depend on ice conditions and the length of time available
for the 2012 drilling season. The predicted ``average'' drilling
season, constrained by prevailing ice conditions and regulatory
restrictions, is long enough for two to three typical exploration wells
to be drilled.
    The actual order of drilling activities will be controlled by an
interplay between actual ice conditions immediately prior to movement
of the NOBLE DISCOVERER, ice forecasts, any regulatory restrictions
with respect to the dates of allowed operating windows, whether the
planned drilling activity involves only drilling the shallow non-
objective section or penetrating potential hydrocarbon zones, the
availability of permitted sites having approved shallow hazards
clearance, the anticipated duration of each contemplated drilling
activity, the results of preceding wells and Marine Mammal Monitoring
and Mitigation plan requirements.
    The planned exploration drilling in the identified lease blocks
will be conducted with the NOBLE DISCOVERER. The NOBLE DISCOVERER is a
true drillship, and is a large self-contained drilling vessel that
offers full accommodations for up to 124 persons. The hull has been
reinforced for ice resistance.
    The NOBLE DISCOVERER has a ``persons on board'' capacity of 124,
and it is expected to be at capacity for most of its operating period.
The NOBLE DISCOVERER's personnel will include its crew, as well as
Shell employees, third party contractors, Alaska Native Marine Mammal
Observers and possibly Bureau of Ocean Energy Management, Regulation
and Enforcement (BOEMRE) personnel.
    While conducting exploration drilling operations, the NOBLE
DISCOVERER will be anchored. The NOBLE DISCOVERER uses an anchoring
system consisting of an 8-point anchored mooring spread attached to the
onboard turret and could have a maximum anchor radius of 3,600 ft
(1,100 m). The anchor spread, which radiates from the center of the
NOBLE DISCOVERER, may pose a fouling hazard to any vessel attempting to
anchor within the anchor spread. Fouling of the NOBLE DISCOVERER anchor
lines may endanger the drillship, its 124 persons onboard the third
party vessel, persons onboard the third party vessel and the
environment.
    The center point of the NOBLE DISCOVERER will be positioned within
the prospect location in the Beaufort or Chukchi Sea at the coordinates
listed below (See Table 1).
    The NOBLE DISCOVERER will transit through the Bering Strait on or
about July 1, 2012 and onto a prospect location when ice allows.
Drilling will be curtailed on or before October 31, 2012. The drillship
and support vessels will depart the Chukchi and Beaufort Seas at the
conclusion of the 2012 drilling season.

Discussion of Comments and Changes

    Three submissions with comments on the proposed rule were received.
No public meeting was requested, and none was held.
    One comment was received suggesting that the safety zone be issued
for a multi-year period similar to safety zones in the Gulf of Mexico.
The Coast Guard disagrees. While the Coast Guard understands that the
underlying justifications for the safety zone are not likely to change
from year to year, we find that there are several operational and
permitting variables with respect to these activities to support not
continuing the safety zones period beyond the current 2012 drilling
season as originally requested. Many of these variables would be
considered substantive changes. Some of the factors that dictate a
season by season publication of the safety zone include the possibility
that a different vessel will be utilized for the exploratory wells;
changes in the published prospect/drilling locations and corresponding
latitude/longitude coordinates; significant changes in any approved
future Outer Continental Shelf Lease Exploration Plans, and the limited
timeframe each year (approximately 4 to 5 months) associated with
actual on site activity. The nature of this activity as noted above is
not currently comparable to the ``manned production facility''
operations in the Gulf of Mexico in that those safety zones are
established for year-round operations on permanent structures that are
engaged in the exploration and production of sub-sea resources. The
Coast Guard will reconsider the temporary nature of these safety zones
should the nature of the operations significantly change from solely
seasonal exploratory drilling operations.
    One comment asked for a clarification with regard to the
probability of a catastrophic event resulting from an

incident. The Coast Guard agrees and has amended the ``Basis and
Purpose'' section of the Final Rule by changing the word ``would'' to
``could'' as it relates to the outcome of an ``allision or inability to
identify, monitor or mitigate ice-related hazards that might be
encountered.''
    One comment requested flexibility with respect to the effective
dates of the temporary safety zone to allow for certain non-drilling
demobilization activities. The Coast Guard understands the nature of
the post-drilling activity and agrees that the safety zone effective
period should be extended to provide that needed flexibility through
November 30, 2012, but only while the vessel is on location as listed
in Table 1 of the rule. The purpose of this change is to ensure the
rule remains effective while the KULLUK completes demobilization
activities on location, thereby enhancing the safety of the personnel
aboard the OCS facility and the environment. The Coast Guard has
amended the final rule to reflect the new effective termination date of
December 1, 2012, so long as the vessel is on location and engaged in
exploratory drilling demobilization activities until this date.
    One comment requested flexibility with respect to dates the
drilling rigs will be engaged in exploratory drilling, noting that the
commencement of drilling activities may not be on July 1, 2012. The
Coast Guard agrees and is amending language relating to the
commencement of drilling activity to be ``on or about'' July 1, 2012.
    One comment requested flexibility with respect to locations
drilling rigs will be operating to state ``Chukchi and/or Beaufort
Seas'' as opposed to ``Chukchi and Beaufort Seas,'' to avoid possible
confusion. The Coast Guard agrees and is amending the regulation
accordingly.
    One comment requested the rule be amended to have the safety zone
in effect once the vessels is ``on location'' while the mooring system
is being deployed or recovered not only when the vessel is anchored.
The Coast Guard agrees. The safety factors that were evaluated in
determining that a safety zone was warranted while the vessel was
anchored on location are substantially similar for when the vessel is
on location and the mooring system is in the process of being deployed
or recovered. The Coast Guard has amended Sec.  147-T17.0024 to read:
``The navigable waters, from the surface to seabed, within 500 meters
(1,640.4 feet) from each point on the outer edge of the vessel, while
anchored or deploying and recovering moorings on location, is a safety
zone.''
    Two comments recommended an extension of the outer boundaries of
the safety zone to include the anchor chain extending from the OCS
facilities; one comment recommended an extension to 1,500 meters from
the vessel, the other recommended the zone extend to 50 meters beyond
the anchor marker buoys of the mobile drilling vessel. The safety zone
extends the maximum distance permitted as per 33 CFR Sec.  147.15,
which establishes the limits of a safety zone at a distance of ``500
meters around the OCS facility.'' Further, the determination that the
outer edge of the OCS facility is marked by the physical structure of
the drilling rig not to include any area encompassed by the anchor
spread is consistent with other safety zones established for other
similar OCS facilities operating on the Outer Continental Shelf, which
is a 500 meter enforcement radius from the outer edge of the OCS
facility structure.
    One comment stated the safety zone should be a moving safety zone
and that it should be extended to all support and tow vessels involved
in the operation and referenced previous safety zones established by
the Coast Guard as precedent. The safety zones referenced by the
commenter were established under the Ports and Waterways Safety Act
(PWSA) (33 U.S.C. 1226(b)), under which the Coast Guard agrees it has
the authority to establish moving safety zones for any vessel operating
within the U.S. territorial seas. The safety zone encompasses areas
outside of the U.S. territorial seas and extends to the maximum extent
permitted by 33 CFR 147.10 which provides a maximum enforcement area of
500 meters from the OCS facility. 33 CFR Sec.  147 does not permit
establishment of safety zones for non-OCS facilities. With respect to
moving safety zones, safety zones may only be enforced while the OCS
facility is being constructed, maintained, or operated on the Outer
Continental Shelf. The Coast Guard, in conjunction with the Department
of State, has determined that this definition does not include times
where the OCS facility is in transit and not directly engaged in
activity related to the exploration or extraction of mineral resources.
Accordingly, the safety zone cannot be implemented or enforced during
times where the OCS facility is in transit. With respect to vessel
movements within the U.S. territorial seas, the Coast Guard is
establishing separate moving safety zones under the PWSA through a
separate rulemaking process which will include safety zones for support
and tow vessels in addition to OCS facilities during periods of transit
within the 12 nautical mile territorial sea in the vicinity of Dutch
Harbor, Alaska.
    One comment requested specific language granting State and Local
officer's enforcement authority under 46 U.S.C. 70118, similar to
safety zones established by the Coast Guard for the Columbia and Snake
Rivers. Title 46 U.S.C. 70118 provides authority for state or local law
enforcement officers to make arrests for safety zones established under
the PWSA or Deepwater Port Act of 1974 (DPA) (33 U.S.C. 1509(d)). The
PWSA does not apply for safety zones established outside of the
territorial seas of the United States, and the DPA does not apply to
the drillship to which the safety zone applies. The authority to
implement this particular safety zone is based upon the Outer
Continental Shelf Lands Act and 33 CFR 147. Accordingly, State and
Local law enforcement officers do not have the authority to take law
enforcement action due to the location of the safety zone.
    One comment stated that the safety zone is overbroad and
unnecessarily restricts first amendment rights. We disagree. The safety
zones were created to facilitate safe navigation and promote the
conduct of safe operations for entities engaging in lawful activities.
However, actions taken which may potentially endanger or threaten
either the individuals operating within this zone or the OCS facility
within this zone will be subject to law enforcement action. There are
no prohibitions on persons exercising free speech; however, actions
that endanger persons or property within the safety zone are
prohibited. Unauthorized vessels operating within this safety zone
create an unnecessary risk to all vessels within the zone, including
themselves. The Coast Guard determined this to be the best course of
action given the complexities in the Arctic, which includes ice
management issues, Marine Mammal Monitoring and Mitigation plan
requirements, the lack of infrastructure in the Arctic, and a harsh,
dynamic offshore environment. These complexities dictate reducing
unnecessary risks associated with vessels not engaged in natural
resource extraction activities operating near the NOBLE DISCOVERER in
order to significantly reduce the threat of allisions and oil spills,
and at the same time increase the safety of life, property, and the
environment in the Chukchi and Beaufort Seas. The Coast Guard believes
that the 500-meter safety zone is ideal because it still provides
sufficient area for persons to peacefully assemble or engage in
legitimate protest activities outside of the safety zone.

    One comment opined that the Coast Guard should be required to
prepare an Environmental Assessment (EA) and Environmental Impact
Statement (EIS) under NEPA. While safety zones are typically
categorically excluded from NEPA analysis, the Coast Guard anticipates
that it will have more assets operating in the Arctic than normal due
to increased vessel traffic in the Arctic. Consequently, the Coast
Guard has undertaken an EA to determine the environmental impacts of
its operations in the Arctic during the summer of 2012, and the
enforcement of the subject safety zones has been included for
consideration of cumulative impacts.
    One comment pointed out that a preliminary environmental analysis
checklist and categorical exclusion determination were stated to be
available in the online record, but was not available. A preliminary
determination was not completed. The Coast Guard is not required to
provide a preliminary environmental analysis checklist and categorical
exclusion determination for a temporary safety zone until publication
of the Final Rule. The reasoning is that safety zones are generally
categorically excluded, and the Coast Guard wanted to review all public
comments before completing the environmental analysis checklist and
categorical exclusion determination in order to ensure that it
accounted for all concerns. The environmental analysis checklist and
categorical exclusion determination for this temporary safety zone is
available in the docket, and can be obtained online following the
direction provided in the ADDRESSES section above.
    One comment stated that the safety zones will cause increased air
pollution because the air permits issued for the NOBLE DISCOVERER
exclude air within the safety zones, and, therefore, the Coast Guard
must undertake a ``NEPA analysis'' to determine the affects of any air
emissions within the safety zone. The Coast Guard does not have the
authority or agency expertise to issue air permits, and, therefore,
does not have the authority to determine whether the issuance of those
permits is appropriate. The safety zones are being implemented to
enhance the safety of vessel operations during a period of increased
vessel traffic at locations where any marine casualty will present
unique challenges due to the remote locations, lack of infrastructure
and unforgiving environmental variables.
    One comment supported the determination to prohibit all vessels,
irrespective of size from the safety zone. The Coast Guard determined
this to be the best course of action given the complexities of this
Arctic operation, which includes ice management issues, Marine Mammal
and Mitigation plan requirements, and a harsh, dynamic offshore
environment. The safety zones will significantly reduce the threat of
allisions and oil spills, and at the same time increase the safety of
life, property, and the environment in the Chukchi and Beaufort Seas. A
change was also made to clarify that the subject safety zones include
``the navigable waters, from the surface to seabed.''

Regulatory Analyses

    The Coast Guard developed this rule after considering numerous
statutes and executive orders related to rulemaking. Below we summarize
our analyses based on 13 of these statutes or executive orders.

Regulatory Planning and Review

    This rule is not a significant regulatory action under section 3(f)
of Executive Order 12866, Regulatory Planning and 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 has not
reviewed it under that Order.
    This rule is not a significant regulatory action due to the
location of the NOBLE DISCOVERER on the Outer Continental Shelf and its
distance from both land and safety fairways. Additional considerations
were the relatively short period of time that the safety zone will be
in effect and the limited size of the safety zone. Vessels traversing
waters near the safety zone will be able to safely travel around the
zone without incurring additional costs.

Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), the Coast
Guard has considered whether this 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.
    The Coast Guard certifies under 5 U.S.C. 605(b) that this rule
would not have a significant economic impact on a substantial number of
small entities. This rule could affect the following entities, some of
which might be small entities: The owners or operators of vessels
intending to transit or anchor in the Sivulliq and Torpedo Prospect of
the Beaufort Sea, including Flaxman Island blocks 6610, 6658 and 6659,
and Posey Blocks 6714, 6762, 6764, 6812, 6912, and 6915 in the Chukchi
Sea. (See Table 1).
    This safety zone will not have a significant economic impact on a
substantial number of small entities for the following reasons: This
rule will enforce a temporary safety zone around a drillship facility
near Flaxman Island of the Beaufort Sea and/or at the Burger Prospect
in the Chukchi Sea, which are both areas not frequented by vessel
traffic and are not in close proximity to a safety fairway. Further,
vessel traffic can pass safely around the safety zone without incurring
additional costs.

Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Public Law 104-121), in the NPRM we offered to
assist small entities in understanding the rule so that they could
better evaluate its effects on them and participate in the rulemaking
process.
    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). 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.

Collection of Information

    This rule would call for no new collection of information under the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).

Federalism

    A rule has implications for federalism under Executive Order 13132,
Federalism, if it has a substantial direct effect on State or local
governments and would either preempt State law or impose a substantial
direct cost of compliance on them. We have analyzed this rule under
that Order and have determined that it does not have implications for
federalism.

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

Taking of Private Property

    This 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.

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.

Protection of Children

    The Coast Guard has 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 would not
create an environmental risk to health or risk to safety that might
disproportionately affect children.

Indian Tribal Governments

    This 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.

Energy Effects

    The Coast Guard 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. 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.

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.

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
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 figure 2-1, paragraph (34)(g), of
the Instruction. This rule involves a temporary final rule for a safety
zone that will be established for 1 week or longer. An environmental
analysis checklist and a categorical exclusion determination are
included in the docket, and can be obtained online by following the
directions delineated in the ``ADDRESSES'' section above. Nevertheless,
while safety zones are typically categorically excluded from NEPA
analysis the Coast Guard anticipates that it will have more assets
operating in the Arctic Ocean than normal due to increased vessel
traffic in the Arctic Ocean. Consequently, the Coast Guard has
undertaken an Environmental Assessment (EA) to determine the
environmental impacts of its overall operations in the Arctic Ocean
during the summer of 2012, and the enforcement of the subject safety
zones has been included for consideration of cumulative impacts. Public
hearings on the draft EA were held on May 30, 2012, in Anchorage,
Alaska, and on May 31, 2012, in Barrow, Alaska.
