Southwest Pass, South Pass, Tiger Pass Including the Mississippi River
Gulf Outlet
AGENCY: Coast Guard, DOT.
ACTION: Notice of study.
-----------------------------------------------------------------------
SUMMARY: The Coast Guard is conducting a port access route study to
evaluate the need for vessel routing or other traffic management
measures in the approaches to the Mississippi River. Concerns for the
safety of navigation in these areas have been expressed by the
Associated Branch Pilots and the Coast Guard Marine Safety Office in
New Orleans, LA. This port access route study will determine what, if
any, vessel routing or other traffic management measures are needed in
the approaches to the Mississippi River and the Mississippi River Gulf
Outlet. As a result of the study, vessel routing measures or other
vessel operating requirements may be proposed in the Federal Register.
DATES: Comments must be received on or before November 19, 1997.
ADDRESSES: Comments should be mailed to Commander (mov-1), Eighth Coast
Guard District, Hale Boggs Federal Building, 501 Magazine Street, New

SUPPLEMENTARY INFORMATION:
Request for Comments
The Coast Guard is interested in receiving information and opinions
from persons who have an interest in safe routing of ships in the study
area. Vessel owners and operators are specifically invited to comment
on any safety concerns they may have when operating in the study area.
Negative impacts that may result from the establishment of a routing
measure, such as a traffic separation scheme (TSS), or a regulated
navigation area (RNA) with vessel operating requirements should be
identified and supported with documentation of any costs or benefits.
Commenters should include their names and addresses, identify this
notice (CGD 97-044), and give reasons for each comment. Receipt of
comments will be acknowledged if a stamped, self-addressed post card or
envelope is enclosed. In addition to the specific questions asked
herein, comments from the maritime community, offshore development
concerns, environmental groups and any other interested parties are
invited. All comments received during the comment period will be
considered in the study and in development of any regulatory proposals.
The Coast Guard intends to hold at least one public meeting to
listen to the users, both commercial and recreational, of the waters in
the study area. We are particularly interested in the source of delays
that slow down commercial vessels and the source of upsets that
interfere with the recreational boaters enjoyment of the waterway.
Details of the meeting will be announced in a separate notice as well
as locally.
The Eighth Coast Guard District will conduct the study and develop
recommendations. Captain M.M. Ledet, Vessel Traffic Management Section,
Marine Safety Branch, Eighth Coast Guard District (504) 589-4686 is the
project officer responsible for the study.
Background and Purpose
The 1978 amendments to the Ports and Waterways Safety Act (PWSA),
33 U.S.C. 1223(c), require that a port access route study be conducted
prior to establishing or adjusting fairways or TSS's. The Coast Guard
is undertaking a port access route study to determine if a vessel
routing system is needed in the study area.
An internationally recognized vessel routing system is one or more
routes or routing measures aimed at reducing the risk of casualties. A
system may include TSS's, two-way routes, recommended tracks, areas to
be avoided, inshore traffic zones, roundabouts, precautionary areas,
and deep-water routes.
A TSS is a routing measure which minimizes the risk of collision by
separating vessels into opposing streams of traffic through the
establishment of traffic lanes.
A two-way route is a route within defined limits inside which two-
way traffic is established, aimed at providing safe passage of ships
through waters where navigation is difficult or dangerous.
A recommended track is a route which has been specially examined to
ensure so far as possible that it is free of dangers and along which
ships are advised to navigate.
An area to be avoided is a routing measure comprising an area
within defined limits in which either navigation is particularly
hazardous or it is exceptionally important to avoid casualties and
which should be avoided by all ships, or certain classes of ships.
An inshore traffic zone comprises a designated area between the
landward boundary of a TSS and the adjacent
[[Page 44429]]
coast and is used in accordance with Rule 10(d) of the 72 COLREGS.
A roundabout is a routing measure comprising a separation point or
circular separation zone and a circular traffic lane within defined
limits. Traffic within the roundabout is separated by moving in a
counterclockwise direction around the separation point or zone.
A precautionary area is a defined area where ships must navigate
with particular caution and within which the direction of traffic flow
may be recommended.
A deep-water route is a route within defined limits which has been
accurately surveyed for clearance of sea bottom and submerged obstacles
as indicated on nautical charts.
The approaches to the Mississippi River and the Mississippi River
Gulf Outlet were last studied in 1984. The study concluded that there
was a need for the establishment of the existing shipping safety
fairways.
The U.S. Army Corps of Engineers' Waterborne Commerce of The United
States reports that, from 1984 to 1993, volume of traffic increased
from 397.1 million tons to 520.3 million tons. Channel depths were
increased to 45 feet in 1994.
The Associated Branch Pilots Association and the Coast Guard's
Marine Safety Office in New Orleans have expressed concern about the
safety of navigation due to the frequency of collisions that have the
potential to close one of the busiest ports in the United States. In
addition to safety concerns, several collisions in the past few years
have demonstrated the potential for far reaching economic impact. The
most recent collision involving the M/V FORMOSA SIX and the M/V FLORA
partially closed the waterway with an estimated cost of over one
million dollars per day.
Study Area
The study area is bounded by a line connecting the following
geographic positions:
Latitude Longitude
29 deg.02'20'' N....................... 89 deg.40'15'' W
29 deg.33'00'' N....................... 89 deg.02'39'' W
29 deg.32'45'' N....................... 88 deg.42'40'' W
29 deg.03'30'' N....................... 88 deg.45'12'' W
28 deg.36'30'' N....................... 89 deg.18'09'' W
28 deg.26'15'' N....................... 89 deg.41'15'' W
The study area encompasses the approaches to the Mississippi River,
the Mississippi River Gulf Outlet as well as the area offshore of
southeast Louisiana used by commercial vessels transiting to and
between these ports.
Issues
The Coast Guard is trying to determine the scope of any safety
problems associated with vessel transit in the study area. It is
expected that information will be gathered during the study that will
identify the problems and appropriate solutions.
In addition to information that you wish to provide, the Coast
Guard is particularly interested in your responses to the following
questions:
1. What is the nature of your work that causes you to navigate in
the study area?
2. How many trips do you make in the study area in a 24-hour
period?
3. What route do you take? Please specify point of origin and
destination?
4. Considering all the passes leading to the Gulf of Mexico, which
would be the most direct to your destination?
5. Are there passes that you do not use? Why not?
6. If the U.S. Corps of Engineers maintained each pass to a
predetermined depth, would you use all the passes?
7. What should be the maintained depth of each pass?
8. Have you had an accident or near miss when transiting the mouth
of the Mississippi River? If so, where? Please describe the incident.
9. Would a traffic separation scheme to separate opposing streams
of traffic help in preventing accidents or near misses?
10. Would improved aids to navigation help in preventing accidents
or near misses? What improvements would you suggest?
11. Would mandatory vessel transit restrictions or operating
requirements in the passes and near shore waters help?
12. Do you have other suggestions to improve navigational safety in
the study area?
The study may recommend the following:
1. No vessel routing measures are needed.
2. Establish one or more of the following vessel routing measures:
(a) TSS in the approach to Southwest Pass of the Mississippi River;
(b) TSS in the approach to the Mississippi River Gulf Outlet;
(c) Precautionary area(s) near either or both approaches; or,
(d) Inshore traffic zone(s) near either or both approaches; and,
3. Establish a regulated navigation area with specific vessel
operating requirements to ensure safe navigation.
Procedural Requirements
In order to provide safe access routes for movement of vessel
traffic proceeding to and from U.S. ports, the PWSA directs that the
Secretary designate necessary fairways and TSS's in which the paramount
right of navigation over all other uses shall be recognized. Before a
designation can be made, the Coast Guard is required to undertake a
study of potential traffic density and the need for safe access routes.
During the study, the Coast Guard is directed to consult with
federal and state agencies and to consider the views of representatives
of the maritime community, port and harbor authorities or associations,
environmental groups, and other parties who may be affected by the
proposed action.
In accordance with 33 U.S.C. 1223(c), the Coast Guard will, to the
extent practicable, reconcile the need for safe access routes with the
needs of all other reasonable uses of the area involved. The Coast
Guard will also consider previous studies and experience in the areas
of vessel traffic management, navigation, shiphandling, the effects of
weather, and prior analysis of the traffic density in certain regions.
Data needed to gain a clear understanding of the waterway and its
uses will be gathered by a contractor. The Coast Guard will focus on
interaction with waterway users and stakeholders to scope out safety
concerns and determine an appropriate solution.
The results of this study will be published in the Federal
Register. If the Coast Guard determines that new routing or other
regulatory measures are needed, a notice of proposed rulemaking will be
published. It is anticipated that the study will be concluded by 30
January 1998.
