33 CFR Part 147

[Docket Number USCG-2023-0277]
RIN 1625-AA00


Safety Zone; Vineyard Wind 1 Wind Farm Project Area, Outer 
Continental Shelf, Lease OCS-A 0501, Offshore Massachusetts, Atlantic 
Ocean

AGENCY: Coast Guard, DHS.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: The Coast Guard is proposing to establish 63 temporary 500-
meter safety zones around the construction of 62 wind turbine 
generators (WTGs) and one electrical service platform (ESP) located in 
the Vineyard Wind 1 Wind Farm (VW1WF) project area within federal 
waters on the Outer Continental Shelf (OCS), specifically in the 
northern portion of Bureau of Ocean Energy Management (BOEM) Renewable 
Energy Lease Area OCS-A 0501, approximately 12 nautical miles (NM) 
offshore of Martha's Vineyard, Massachusetts and 12 NM offshore 
Nantucket, Massachusetts. This action is necessary to provide for the 
safety of life, property, and the environment during the planned 
construction of each facility's monopile type foundation and subsequent 
installation of the WTGs turbines and ESP platform from June 15, 2023, 
to May 31, 2024. When enforced, only attending vessels and those 
vessels specifically authorized by the First Coast Guard District 
Commander, or a designated representative, are permitted to enter or 
remain in the temporary safety zones. We invite your comments on this 
proposed rulemaking.

DATES: Comments and related material must be received by the Coast 
Guard on or before June 2, 2023.

ADDRESSES: You may submit comments identified by docket number USCG-
2023-0277 using the Federal Decision-Making Portal at https://www.regulations.gov. See the ``Public Participation and Request for 
Comments'' portion of the SUPPLEMENTARY INFORMATION section for further 
instructions on submitting comments.

FOR FURTHER INFORMATION CONTACT: If you have questions about this 
proposed rulemaking, call or email Mr. Craig Lapiejko, Waterways 
Management, at Coast Guard First District, telephone 617-603-8592,

II. Background, Purpose, and Legal Basis

    On March 15, 2023, Vineyard Wind, LLC, an offshore wind farm 
developer, notified the Coast Guard that they plan to begin 
construction of facilities in the VW1WF project area within federal 
waters on the OCS, specifically in the northern portion of BOEM 
Renewable Energy Lease Area OCS-A 0501, approximately 12 NM offshore 
Martha's Vineyard, Massachusetts and 12 NM offshore Nantucket, 
Massachusetts in June 2023.
    The extremely complex offshore construction of these OCS facilities 
presents many unusually hazardous conditions including hydraulic pile 
driving hammer operations, heavy lift operations, overhead cutting 
operations, potential falling debris, increased vessel traffic, and 
stationary barges in close proximity to the facilities and each other.
    Based on these circumstances, the First Coast Guard District 
Commander has determined that establishment of 63 temporary safety 
zones through rulemaking is warranted to ensure the safety of life, 
property, and the environment within a 500-meter radius of each of the 
63 facilities during their construction.
    The Coast Guard is proposing this rule under the authorities 
provided in 14 U.S.C. 544, 43 U.S.C. 1333, and Department of Homeland 
Security (DHS) Delegation No. 00170.1, Revision No. 01.3. As an 
implementing regulation of this authority, 33 CFR part 147 permits the 
establishment of safety zones for non-mineral energy resource permanent 
or temporary structures located on the OCS for the purpose of 
protecting life and property on the facilities, appurtenances and 
attending vessels, and on the adjacent waters within the safety zone 
(see 33 CFR 147.10). Accordingly, a safety zone established under 33 
CFR part 147 may also include provisions to restrict, prevent, or 
control certain activities, including access by vessels or persons to 
maintain safety of life, property, and the environment. If, as we 
anticipate, we issue a temporary final rule and make it effective less 
than 30 days after publication in the Federal Register, we will explain 
in that publication, as required by 5 U.S.C. (d)(3), our good cause for 
doing so.

III. Discussion of Proposed Rule

    The District Commander is proposing to establish 63 temporary 500-
meter safety zones around the construction of 62 WTGs and one ESP on 
the OCS from June 15, 2023, through 11:59 p.m. on May 31, 2024.
    The construction of these facilities is expected to take place in 
mixed phases alternating between the installation of several monopile 
type foundations followed by the installation of the upper structures 
then repeating this process throughout the project area until all 63 
facilities have been completed. The 63 temporary safety zones would be 
enforced individually as construction progresses from one structure 
location to the next throughout the entire process for a period lasting 
approximately 48 hours. The Coast Guard would make

[[Page 27840]]

notice of each enforcement period via the Local Notice to Mariners and 
issue a Broadcast Notice to Mariners via marine channel 16 (VHF-FM) as 
soon as practicable in response to an emergency or hazardous condition. 
The Coast Guard is publishing this rulemaking to be effective, and 
enforceable, through May 31, 2024, to encompass any construction delays 
due to weather or other unforeseen circumstances. If the project is 
completed before May 31, 2024, enforcement of the safety zones would be 
suspended, and notice given via Local Notice to Mariners.
    Additional information about the construction process of the VW1WF 
can be found at https://www.boem.gov/vineyard-wind.
    The 63 temporary 500-meter safety zones around the construction of 
62 WTGs and one ESP are in the VW1WF project area, specifically in the 
northern portion of BOEM Renewable Energy Lease Area OCS-A 0501, 
approximately 12 NM offshore of Martha's Vineyard, Massachusetts and 12 
NM offshore Nantucket, Massachusetts, within federal waters on the OCS.
    The positions of each individual safety zone proposed by this 
rulemaking will be referred to using a unique alpha-numeric naming 
convention outlined in the ``Rhode Island and Massachusetts Structure 
Labeling Plot (West).'' \1\

BILLING CODE 9110-04-C
    Navigation in the vicinity of the proposed safety zones consists of 
large commercial shipping vessels, fishing vessels, cruise ships, tugs 
with tows, and recreational vessels.
    When enforced, no unauthorized vessel or person would be permitted 
to enter the safety zone without obtaining permission from the First 
Coast Guard District Commander or a designated representative. Requests 
for entry into the safety zone would be considered and reviewed on a 
case-by-case basis. Persons or vessels seeking to enter the safety zone 
must request authorization from the First Coast Guard District 
Commander or designated representative via VHF-FM channel 16 or by 
phone at 617-603-1560 (First Coast Guard District Command Center). If 
permission is granted, all persons and vessels shall comply with the 
instructions of the First Coast Guard District Commander or designated 
representative.
    The proposed regulatory text appears at the end of this document.

IV. Regulatory Analyses

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

A. Regulatory Planning and Review

    Executive Orders 12866 and 13563 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. This NPRM has not been designated a ``significant 
regulatory action,'' under Executive Order 12866. Accordingly, the NPRM 
has not been reviewed by the Office of Management and Budget (OMB).
    Aligning with 33 CFR 147.15, the safety zones established would 
extend to a maximum distance of 500-meters around the OCS facility 
measured from its center point. Vessel traffic would be able to safely 
transit around the proposed safety zones, which would impact a small, 
designated area in the Atlantic Ocean, without significant impediment 
to their voyage. This safety zone would provide for the safety of life, 
property, and the environment during the construction of each 
structure, in accordance with Coast Guard maritime safety missions.

B. Impact on Small Entities

    The Regulatory Flexibility Act of 1980, 5 U.S.C. 601-612, as 
amended, requires Federal agencies to consider the potential impact of 
regulations on small entities during rulemaking. 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 
proposed rule would not have a significant economic impact on a 
substantial number of small entities.
    This rule may affect owners or operators of vessels intending to 
transit or anchor in the VW1WF, some of which might be small entities. 
However, these safety zones would not have a significant economic 
impact on a substantial number of these entities because they are 
temporarily enforced, allow for deviation requests, and do not impact 
vessel transit significantly. Regarding the enforcement period, 
although these safety zones would be in effect from June 15, 2023, 
through May 31, 2024, vessels would only be prohibited from the 
regulated zone during periods of actual construction activity in 
correspondence to the period of enforcement. We expect the enforcement 
period at each location to last approximately 48 hours as construction 
progresses from one structure location to the next throughout the mixed 
phases. Additionally, vessel traffic could pass safely around each 
safety zone using an alternate route. Use of an alternate route likely 
will cause minimal delay for the vessel in reaching their destination 
depending on other traffic in the area and vessel speed. Vessels would 
also be able to request deviation from this rule to transit through a 
safety zone. Such requests would be considered on a case by-case basis 
and may be authorized by the First Coast Guard District Commander or a 
designated representative. For these reasons, the Coast Guard expects 
any impact of this rulemaking establishing a temporary safety zone 
around these OCS facilities to be minimal and have no significant 
economic impact on small entities.
    If you think that your business, organization, or governmental 
jurisdiction qualifies as a small entity and that this proposed rule 
would have a significant economic impact on it, please submit a comment 
(see ADDRESSES) explaining why you think it qualifies and how and to 
what degree this rule would economically affect it.
    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 proposed rule. If the proposed rule 
would affect your small business, organization, or governmental 
jurisdiction and you have questions concerning its provisions or 
options for compliance, please call or email the person listed in the 
FOR FURTHER INFORMATION CONTACT section. The Coast Guard will not 
retaliate against small entities that question or complain about this 
proposed rule or any policy or action of the Coast Guard.

C. Collection of Information

    This proposed rule would not call for a new collection of 
information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-
3520).

D. Federalism and Indian Tribal Governments

    A rule has implications for federalism under Executive Order 13132 
(Federalism), if it has a substantial direct effect on the States, on 
the relationship between the National Government and the States, or on 
the distribution of power and responsibilities among the various levels 
of government. We have analyzed this proposed rule under that Order and 
have determined that it is consistent with the fundamental federalism 
principles and preemption requirements described in Executive Order 
13132.
    Also, 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. If 
you believe this proposed rule has implications for federalism or 
Indian tribes, please call or email the person listed in the FOR 
FURTHER INFORMATION CONTACT section.

E. 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 potential effects of 
this proposed rule elsewhere in this preamble.

[[Page 27844]]

F. Environment

    We have analyzed this proposed rule under Department of Homeland 
Security Directive 023-01, Rev. 1, associated implementing 
instructions, and Environmental Planning COMDTINST 5090.1 (series), 
which guide the Coast Guard in complying with the National 
Environmental Policy Act of 1969 (42 U.S.C. 4321-4370f), and have made 
a preliminary determination that this action is one of a category of 
actions that do not individually or cumulatively have a significant 
effect on the human environment. This proposed rule involves the 
establishment of a safety zone around an OCS facility to protect life, 
property, and the marine environment. Normally such actions are 
categorically excluded from further review under paragraph L60 of 
Appendix A, Table 1 of DHS Instruction Manual 023-01-001-01, Rev. 1. A 
preliminary Record of Environmental Consideration supporting this 
determination is available in the docket. For instructions on locating 
the docket, see the ADDRESSES section of this preamble. We seek any 
comments or information that may lead to the discovery of a significant 
environmental impact from this proposed rule.

G. Protest Activities

    The Coast Guard respects the First Amendment rights of protesters. 
Protesters are asked to call or email the person listed in the FOR 
FURTHER INFORMATION CONTACT section to coordinate protest activities so 
that your message can be received without jeopardizing the safety or 
security of people, places, or vessels.
