Traffic Separation Scheme; In The Approaches to Chesapeake Bay
AGENCY: Coast Guard, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Coast Guard amends the traffic separation scheme (TSS) in
the Approaches to Chesapeake Bay by realigning and reconfiguring the
Southern Approach to incorporate a deep-water (DW) route. The Coast
Guard suspended the Southern approach lanes on October 15, 1988,
because the water depth was too shallow to accommodate the deeper draft
vessels which were able to call on the port after completion of a U.S.
Army Corps of Engineers (COE) channel deepening project in Hampton
Roads. The realigned and reconfigured Southern Approach utilizes
naturally occurring deeper water and incorporates the proposed Atlantic
Ocean Channel, a U.S. Army Corps of Engineers navigation improvement
project.
EFFECTIVE DATES: May 31, 1994.

Drafting Information
The principal persons involved in drafting this document are Margie
G. Hegy, Project Manager, John R. Walters, Project Officer, Fifth Coast
Guard District Portsmouth, VA, and Helen G. Boutrous, Project Counsel,
Office of Chief Counsel.
Regulatory History
On September 6, 1990, the Coast Guard published a notice of
proposed rulemaking entitled ``Traffic Separation Scheme; In the
Approaches to Chesapeake Bay'' in the Federal Register (55 FR 36666).
The Coast Guard received six letters commenting on the proposal. A
public hearing was not requested and one was not held.
Background and Purpose
The Ports and Waterways Safety Act (PWSA), 33 U.S.C. 1223
authorizes the Secretary of the Department in which the Coast Guard is
operating to establish TSSs and shipping safety fairways, where
necessary, to provide safe access routes for vessels proceeding to or
from United States ports.
A TSS is an internationally recognized routing measure that
minimizes the risk of collision by separating vessels into opposing
streams of traffic through the establishment of traffic lanes. To be
internationally recognized, a TSS must be approved by the International
Maritime Organization (IMO). IMO approves a TSS only if the proposed
routing system complies with IMO principles and guidelines on ships'
routing. Vessel use of a TSS is voluntary; however, vessels operating
in or near an IMO approved TSS are subject to Rule 10 of the
International Regulations for Preventing Collisions at Sea, 1972 (72
COLREGS), 33 U.S.C. foll. 1602.
The TSS in the Approaches to Chesapeake Bay was established on
December 1, 1969, and was adopted by IMO on October 12, 1971. In
consists of three parts: Part I, Precautionary Area; Part II, Eastern
Approach; and Part III, Southern Approach.
Regulatory Background
The 1978 amendments to the PWSA required the Coast Guard to
undertake a port access route study to determine the need for TSSs or
shipping safety fairways to increase vessel traffic safety in offshore
areas subject to the jurisdiction of the United States. The Coast Guard
initiated this study by publishing a notice of study on April 16, 1979
(44 FR 22543). The final notice of study results for the TSS in the
Approaches to Chesapeake Bay was published on July 22, 1982 (47 FR
31766). The study concluded that the existing TSS was adequate for the
foreseeable future.
The Water Resources Development Act of 1986, Public Law 99-662, (33
U.S.C. 2201 et seq.) authorized the deepening of the Thimble Shoals,
Newport News, Craney Island Reach, Norfolk Harbor Reach, and the
Entrance Reach Channels in the port of Hampton Roads to a depth of 55'
below mean low water (MLW) and construction of a new channel, to be
known as the Atlantic Ocean Channel. The Atlantic Ocean Channel will
connect deep water at the entrance to Chesapeake Bay with deep water in
the Atlantic Ocean.
Completion of the dredging of all channels except the Atlantic
Ocean Channel to 50' (MLW) allows vessels with drafts exceeding the
water depths in the existing Southern Approach lanes to call on the
ports of Hampton Roads. The COE conducted hydrographic surveys in 1985
and 1986 and found that the water depth in the Southern Approach lanes
was only 48' (MLW); however, water depths of 50' were found in the
immediate vicinity. To ensure safe navigation for vessels with drafts
exceeding the water depth in the Southern Approach lanes, the Coast
Guard suspended the Southern Approach lanes (Notice to Mariners No. 31,
July 30, 1988). A system of safewater buoys was established, as an
interim measure, to direct vessels to naturally occurring deeper waters
in the immediate vicinity.
The Coast Guard opened a Port Access Route Study on July 12, 1988
(53 FR 26282). The study, conducted by the Fifth Coast Guard District
in Portsmouth, VA, evaluated the need for vessel routing measures in
the approaches to Chesapeake Bay. The study area encompassed the
approaches to Chesapeake Bay, including the TSS.
The study results were published on July 13, 1989, at 54 FR 29627.
The study, concluding that there is a continuing need for the TSS,
recommended that the Southern Approach be realigned and reconfigured to
incorporate a deep-water route with specific rules for vessels
operating therein.
A deep-water route is an internationally recognized routing measure
primarily intended for use by ships, which because of their draft in
relation to the available depth of water in the area concerned, require
the use of such a route. In the Southern Approach, water depths outside
of the planned deep water route are insufficient for use by vessels
drawing more than 45' of water. It is also a general requirement of IMO
that traffic which does not require the use of the deep-water route
should avoid using the route.
The Coast Guard submitted the amended TSS, as proposed in the NPRM,
to IMO's Subcommittee on Safety of Navigation (NAV) for consideration
and approval at its September 1990 meeting. The Subcommittee approved
the establishment of a deep-water route between the traffic lanes of
the southern approach of the TSS as proposed by the U.S., but ``could
not agree with the proposal to recommend the use of the deep-water
route by certain ships with a draft of less than 45' (13.5 meters)
which need not use the deep-water route.'' The Subcommittee amended the
U.S. proposal accordingly and forwarded it to IMO's Maritime Safety
Committee for consideration and adoption. The Committee adopted the
revised proposal at its May 1991 meeting for implementation at 0000
hours UTC, 0500 Eastern Time Zone, on 16 November 1991.
The Coast Guard is reconfiguring the Southern Approach, which is
crucial to continued navigation safety and protection of the marine
environment, and publishing the Precautionary Area and Eastern Approach
parts of the existing TSS.
The Southern Approach consists of inbound and outbound lanes for
vessels drawing 45' of water or less, separated by a 1300' wide deep-
water route for inbound and outbound vessels drawing over 45' of water
and for naval aircraft carriers.
Both the inbound and outbound lanes for vessels drawing 45' feet of
water or less measure 0.75 nautical miles (1500 yards) in width as
determined by multiplying the published standard error of LORAN-C (0.25
NM) by three. Because of the low-lying coast of the Commonwealth of
Virginia and the lack of prominent landmarks, LORAN-C remains an
acceptable aid to navigation for use in these inbound and outbound
lanes.
The deep water route, for vessels drawing over 45' of water,
measures 1300' in width and has a charted natural depth of 50' or
greater. As currently planned, the COE will construct the Atlantic
Ocean Channel in this location when funds become available in both the
Federal and Commonwealth of Virginia budgets. Due to uncertain economic
conditions, a dredging completion date is unknown.
Discussion of Comments and Changes
Six written comments were received in response to the notice of
proposed rulemaking. Five comments fully support establishment of the
traffic separation scheme and the sixth comment offered editorial
suggestions. Specific comments pertaining to other aspects of the
proposal are discussed below.
The U.S. Army Corps of Engineers (COE) advised that due to
budgetary consideration in the Commonwealth of Virginia, dredging of
the Atlantic Ocean Channel would be rescheduled to an indefinite time
in the future. The COE also pointed out an error in one of the
geographical positions for the inbound traffic lane. This information
has been corrected in the final rule.
One comment, which is not adopted in this final rule, suggested
that the draft limitation for use of the deep-water route be changed to
``vessels drawing 45 feet or more'' while four comments agreed with the
proposal to provide vessels drawing greater than 45 feet exclusive use
of the deep-water route.
Five comments strongly objected to the proposal to recommend that
all vessels carrying dangerous cargo and petroleum distillates as cargo
use the deep-water route. IMO's Subcommittee on Safety of Navigation
also objected to this provision and amended the U.S. proposal to
exclude it from consideration and adoption by the Maritime Safety
Committee. Based on the comments and IMO's action, this proposed
recommendation is deleted from this final rule.
Three comments objected to naval aircraft carriers using the deep-
water route. In response to the notice of study, the U.S. Navy
requested that it be allowed to use the deep-water route to ensure the
continued safe, uneventful transit of aircraft carriers to and from
sea. The Coast Guard and IMO agree that aircraft carrier usage of the
deep-water route will enhance navigation safety and therefore will be
permitted.
One comment suggested placement of a buoy near latitude
36 deg.54.43' longitude 75 deg.53.2'W to mark lesser water depths
adjacent to the inbound traffic lane. The 1500-yard inbound lane, with
the use of LORAN-C or radar, is sufficient to allow safe passage
through the area without the placement of a buoy. Therefore, this
comment is not adopted.
Three comments disagreed with the proposed recommendation that
vessels announce their intentions to use the deep-water route. One
comment objected to Channel 16 VHF-FM usage because of frequency
congestion by other users. Two comments recommended that vessels call
at least one hour prior to entering the deep-water route instead of at
the time the vessel approaches Chesapeake Bay Southern Approach Lighted
Whistle Buoy CB on the south end, or Chesapeake Bay Junction Lighted
Buoy CBJ on the north end of the route, as proposed in the NPRM. The
Coast Guard realizes that Channel 16 is crowded, however it is
recognized as the distress, safety, and calling frequency in the United
States and internationally as evidenced by IMO's adoption of this
recommended practice. If the exchange of additional information is
required, shifting to another VHF-FM channel would be appropriate.
Other minor editorial and administrative changes have been made to
improve the clarity of this part.
Regulatory Evaluation
This regulation is not a significant regulatory action under
section 3(f) of Executive Order 12866 and non-significant under the DOT
regulatory policies and procedures (44 FR 11034; February 26, 1979).
Vessels have been complying with the requirements of this rule since
IMO implementation on November 16, 1991. No additional costs are
associated with this final rule. The Coast Guard expects the economic
impact of this rule to be so minimal that a full Regulatory Evaluation
under paragraph 10e of the regulatory policies and procedures of DOT is
unnecessary.
Small Entities
There are no additional costs associated with this final rule as
vessels have been using the newly configured southern approach lanes
since it was implemented by IMO on November 16, 1991. Therefore, the
Coast Guard certifies under Section 605(b) of the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.) that this final rule will not
have a significant economic impact on a substantial number of small
entities.
Collection of Information
This rule contains no collection of information requirements under
the Paperwork Reduction Act (44 U.S.C. 3501 et seq.).
Federalism
The Coast Guard has analyzed this rule in accordance with the
principles and criteria contained in Executive Order 12612 and has
determined that this rule does not have sufficient federalism
implications to warrant the preparation of a Federalism Assessment.
The authority to establish TSSs and shipping safety fairways, where
necessary, to provide safe across routes for vessels proceeding to or
from U.S. ports is committed to the Coast Guard by Federal Statute.
Therefore, the Coast Guard does not expect this rule to raise any
preemption issues with respect to state actions on the same subject
matter.
Environmental Impact
The Coast Guard has determined that this action will not have a
significant impact on the environment and that an environmental impact
statement is not necessary. A Finding of No Significant Impact (FONSI)
is on file in the docket for inspection or copying where indicated
under ADDRESSES. Comments received as a result of the NPRM did not
address any environmental concerns.
