[Docket Number USCG-2021-0327]
RIN 1625-AA00


Safety Zone; Patapsco River, Baltimore, MD

AGENCY: Coast Guard, DHS.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: The Coast Guard is proposing to establish a temporary safety 
zone for certain waters of the Patapsco River. This action is necessary 
to provide for the safety of life on these navigable waters near the 
Francis Scott Key (I-695) Bridge, Baltimore, MD. This temporary safety 
zone is intended to restrict vessel traffic on the Patapsco River from 
September 1, 2021, through November 17, 2021, while work crews install 
power transmission lines crossing over the river. This proposed 
rulemaking would prohibit persons and vessels from being in the safety 
zone unless authorized by the Captain of the Port Maryland-National 
Capital Region or a designated representative. We invite your comments 
on this proposed rulemaking.

DATES: Comments and related material must be received by the Coast 
Guard on or before July 16, 2021.

ADDRESSES: You may submit comments identified by docket number USCG-
2021-0327 using the Federal eRulemaking 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.

II. Background, Purpose, and Legal Basis

    On May 12, 2021, Baltimore Gas and Electric Company (BGE) provided 
the Coast Guard with details concerning activities associated with the 
installation of two new overhead power transmission lines crossing over 
the Patapsco River, from the vicinity of the Hawkins Point terminal 
Station on the west side of the Patapsco River to a location just north 
of Sollers Point Terminal Station on the east side of the Patapsco 
River, to be conducted from September 1, 2021, through November 17, 
2021. BGE's 11-week work schedule includes both primary and alternate 
workdays on Mondays through Fridays, with no work scheduled on 
weekends. The activities for wire stringing and the installation of the 
associated hardware for the project requires the use of a helicopter. 
The new overhead line segment will be supported by new steel monopole 
towers at eight locations, five of which will be in the Patapsco River. 
These in-water towers will range in height from 126 feet to 397 feet 
above the Patapsco River and will support two 230kV transmission 
circuits. Work will be done above and across the Patapsco River, on and 
between the steel towers located at approximate positions 
39[deg]12'46.87'' N, 076[deg]32'14.05'' W; 39[deg]12'58.56'' N, 
076[deg]31'58.74'' W; 39[deg]13'13.79'' N, 076[deg]31'38.79'' W; 
39[deg]13'26.61'' N, 076[deg]31'21.98'' W; and 39[deg]13'39.43'' N, 
076[deg]31'05.18'' W (NAD 1983), and those towers and the terminal 
stations located on shore. The span lengths between the in-water towers 
will range from 373 feet to 2,200 feet. The tallest towers and the high 
wire tensions used to support the wires in the 2,200 foot span that 
crosses the Fort McHenry Channel in Baltimore Harbor will be at a 
height of no less than 231 feet above the water. This installation 
process requires the temporary closure of the navigation channel near 
the Francis Scott Key (I-695) Bridge and the temporary closure of other 
portions of the Patapsco River nearby, including on multiple days 
during the stated installation period. A safety zone is proposed within 
the immediate vicinity of the power transmission line crossing. Hazards 
from the installation of overhead power transmission lines include low-
hanging or falling ropes and cables, helicopter rotor downwash and 
noise, dangerous projectiles, and or other debris. The COTP Maryland-
National Capital Region has determined that potential safety hazards 
associated with overhead power transmission line installation work 
would be a concern for anyone transiting the Patapsco River.
    The purpose of this rule is to protect persons, vessels, and the 
marine environment on the navigable waters of the Patapsco River during 
the installation of overhead power transmission lines crossing over the 
river. The Coast Guard is proposing this rulemaking under authority in 
46 U.S.C. 70034 (previously 33 U.S.C. 1231).

III. Discussion of Proposed Rule

    The COTP is proposing to establish a temporary safety zone on a 
portion of the Patapsco River from September 1, 2021, through November 
17, 2021, to be enforced while BGE installs overhead power transmission 
lines over the river. BGE reports its work crews will need to access 
the navigation channel and other portions of the Patapsco River near 
the Francis Scott Key (I-695) Bridge as outlined in the following 
sequence of activities for each of two circuits. The safety zone would 
be enforced during the times described below for each activity.

A. Installation of Circuit 2345

    1. Activity #1: Fly the ropes into blocks. September 1, 2021, 
(alternate date September 7, 2021) and September 2, 2021, (alternate 
date September 8, 2021). On those dates, helicopter flights will be 
conducted to fly-in two rope spans. A full river closure is required 
for both flights. The first river closure would occur from 9 a.m. to 
10:30 a.m. After this period, the helicopter will fly back to the 
staging area to re-fuel and prepare for the next rope pull and the 
river would open to vessel traffic. The second river closure would 
occur from 1 p.m. to 2:30 p.m. The river would close for the helicopter 
to complete the second pull.
    2. Activity #2: Preparation to pull conductor. No activities 
requiring closure of navigation channel and other portions of the 
Patapsco River are planned from September 9, 2021 through September 12, 
2021. On those dates, pull equipment will be set up at designated land-
based locations.
    3. Activity #3: Pull and clip in conductor and cable. September 13, 
2021, (alternate date September 15, 2021), September 20, 2021, 
(alternate date September 22, 2021), September 24, 2021, (alternate 
date September 28, 2021), and September 27, 2021, (alternate date 
September 29, 2021). On September 13, 2021, September 20, 2021, and, 
September 24, 2021, equipment pulling operations will be conducted to 
pull the hardline across the river using the rope that were previously 
strung and the conductor pair across the river using the hardline. A 
full river closure is required for each pull. The first closure would 
occur from 9 a.m. to 10:30 a.m. After this period, the conductor reels 
will be re-set and prepared for the next pull, and the river would open 
to vessel traffic. The second closure would occur from 1 p.m. to 2:30 
p.m. The river would close for the conductor reels to complete the 
second pull. On September 27, 2021, a full river closure is required 
for one pull. This closure would occur from 9 a.m. to 10:30 a.m.
    4. Activity #4: Install dampers, spacers, and marker balls. October

14th. On November 8, 2021 (alternate date November 10, 2021), 
specifically, helicopter flights will be conducted to transport 
personnel and equipment to the tower locations for workers to install 
dampers.
    Due to the nature of the work and the hazards it presents to the 
workers and the public, the COTP has identified the need to close the 
Patapsco River near the Francis Scott Key (I-695) Bridge while this 
work is ongoing. On days the safety zone would be enforced, the 
affected area of the river would be closed during the dates and times 
scheduled. These dates and times may change due to weather, or for any 
reason that the primary dates and times could not be used. Alternative 
dates have been provided in the event the primary dates can not be 
used. Exact dates and times would be announced by broadcast notice to 
mariners, between one and five days in advance of the scheduled date, 
to alert mariners of the change. This safety zone would cover all 
navigable waters of the Patapsco River, encompassed by a line 
connecting the following points beginning at the shoreline at Thoms 
Cove at position latitude 39[deg]12'36'' N, longitude 076[deg]32'50'' 
W, thence east and south along the shoreline to Hawkins Point at 
latitude 39[deg]12'40'' N, longitude 076[deg]31'58'' W, thence 
northeast across the Patapsco River to Coffin Point at latitude 
39[deg]13'55'' N, longitude 076[deg]30'18'' W, thence west and north 
along the shoreline to Sollers Point at latitude 39[deg]14'01'' N, 
longitude 076[deg]30'59'' W, thence west across the Patapsco River to 
and terminating at the point of origin, located at Baltimore, MD. The 
safety zone is approximately 4,000 yards in length and 900 yards in 
width.
    This proposed rule provides additional information about areas 
within the safety zone and their definitions. These areas include 
``Area 1,'' ``Area 2,'' ``Area 3,'' ``Area 4,'' ``Area 5,'' and ``Area 
6.'' A diagram of the tower locations is provided in the docket folder. 
For instructions on locating the docket, see the ADDRESSES section of 
this preamble.
    The duration of the rule and enforcement of the zone is intended to 
ensure the safety of personnel, vessels, and the marine environment in 
these navigable waters while the activities associated with the 
installation of two new overhead power transmission lines crossing over 
the Patapsco River are being conducted. The COTP would notify the 
public that the safety zone will be enforced by all appropriate means 
to the affected segments of the public, as practicable, in accordance 
with 33 CFR 165.7(a). Such means of notification may also include, but 
are not limited to, Broadcast Notice to Mariners. Vessels or persons 
violating this rule are subject to the penalties set forth in 46 U.S.C. 
70036 (previously codified in 33 U.S.C. 1232) and 46 U.S.C. 70052 
(previously codified in 50 U.S.C. 192).
    Except for craft and equipment operated by BGE, or its 
subcontractors, no vessel or person would be permitted to enter the 
safety zone without obtaining permission from the COTP or a designated 
representative. The regulatory text we are proposing 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. Below we summarize our 
analyses

[[Page 32003]]

based on a number of these statutes and Executive orders, and we 
discuss First Amendment rights of protestors.

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).
    This regulatory action determination is based on the size, 
duration, day-of-week, and time of year of the proposed safety zone, 
which would impact a small designated area of the Patapsco River during 
certain weekdays (Mondays through Fridays, including holidays). Vessels 
or persons would not be allowed to enter or transit a portion of the 
Patapsco River for a total 97 enforcement-hours, over an 11-week period 
from September 1, 2021, through November 17, 2021, during active 
overhead power transmission line installation activities as described 
in the text above. The closures are scheduled to impose the least 
amount of impact on vessel operations in Baltimore Harbor. Due to the 
nature of the work and the hazards it presents to the workers and the 
public, the COTP has identified the need to close the Patapsco River in 
the vicinity of the overhead power line crossing while this work is 
ongoing. Moreover, the Coast Guard will issue Local Notices to Mariners 
and a Broadcast Notice to Mariners via VHF-FM marine channel 16 about 
the zone.

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.
    While some owners or operators of vessels intending to transit the 
safety zone may be small entities, for the reasons stated in section 
IV.A above, this proposed rule would not have a significant economic 
impact on any vessel owner or operator.
    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 (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 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 effects of this rule 
elsewhere in this preamble.

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 a safety 
zone lasting 97 total enforcement hours that would prohibit entry 
within portions of the Patapsco River. Normally such actions are 
categorically excluded from further review under paragraph L60(a) 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.

V. Public Participation and Request for Comments

    We view public participation as essential to effective rulemaking, 
and will consider all comments and material received during the comment 
period. Your comment can help shape the outcome of this rulemaking. If 
you submit a comment, please include the docket number for this 
rulemaking, indicate the specific section of this document to which 
each comment

[[Page 32004]]
