33 CFR Part 401

RIN 2135-AA00


Seaway Regulations and Rules: Miscellaneous Amendments

AGENCY: Saint Lawrence Seaway Development Corporation, DOT.

ACTION: Final rule.

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

SUMMARY: The Saint Lawrence Seaway Development Corporation and the St. 
Lawrence Seaway Authority of Canada publish joint Seaway Regulations. 
As a result of discussions with the Authority, it has been determined 
that a number of existing regulations need to be amended for 
clarification or simplification. In addition, several substantive 
changes are being made, specifically: changing the maximum allowable 
beam from 23.16 m (76 feet) to 23.8 m (78 feet), with certain, 
practical conditions applied; reducing the security deposit for certain 
vessels; requiring permanent fenders, with a phase-in period; and 
reducing some of the system's speed limits. The first two of these are 
intended to encourage increased usage of the Seaway, the third is 
intended to increase the safety for both the Corporation's and the 
Authority's locks and the vessels transiting, and the fourth is 
intended to increase both safety and environmental protection.

DATES: This rule is effective on June 3, 1996.

FOR FURTHER INFORMATION CONTACT:
Marc C. Owen, Chief Counsel, Saint Lawrence Seaway Development 
Corporation, 400 Seventh Street, S.W., Washington, D.C. 20590, (202) 
366-6823.

SUPPLEMENTARY INFORMATION: As a result of discussions with the Saint 
Lawrence Seaway Authority of Canada, the Saint Lawrence Seaway 
Development Corporation is amending the Seaway Regulations and Rules in 
33 CFR Part 401 as described in the following summary.
    Section 401.3, ``Maximum vessel dimensions'', is amended by 
revising paragraph (a), removing paragraph (d)(1), and adding a new 
paragraph (e) to change the maximum allowable beam from 23.16 m (76 
feet) to 23.8 m (78 feet)

[[Page 19549]]

and simplify the approval process for vessels exceeding 23.2 m., with 
practical conditions applied for such things as vessel configuration 
and weather conditions.
    Section 401.6, ``Markings'', is amended by revising paragraphs (a) 
and (b) to round off the length requirements from 19.8 m to 20.0 m and 
from 117 m to 110 m, respectively, for simplification and consistency 
with the international collision regulations. To alleviate safety 
problems caused by portable fender usage, Sec. 401.7, ``Fenders'', is 
revised to require, as a rule, permanent fenders of a specified type, 
with only occasional deployment of portable fenders allowed on a single 
transit basis, with a phase-in period until the beginning of the 1997 
navigation season to ease transition. One comment suggested the 
elimination of permanent fenders because they can catch the lock gates 
and, at certain vessel drafts, can dig into the wooden fenders on the 
lock approach walls. The Corporation and the Authority are not adopting 
this suggestion. Permanent fenders are being required to avoid the 
situation where mooring wires may be crushed between the vessel's side 
and the lock wall, to prevent steel contact on vessels with hazardous 
cargo stored in side tanks, and, occasionally for certain vessels, to 
protect specific structures or provide adequate clearance off bascule 
bridges. The Authority and the Corporation review vessel plans to 
ensure that fenders are located as high on the hull as possible, have a 
maximum size stipulated, and are adequately tapered. If these plans are 
provided and concurred in before construction or retrofitting, the type 
of problem suggested by the comment should be avoided.
    Section 401.9, ``Radiotelegraph equipment'', is amended by revising 
paragraph (a) to round off the length requirement for self-propelled 
vessels from 19.8 m to 20.0 m for simplification.
    Section 401.10, ``Mooring lines'', is amended by revising 
paragraphs (B) and (c) to allow routinely synthetic lines since vessels 
now use them routinely and safely worldwide.
    Section 401.13, ``Hand lines'', is amended by revising paragraph 
(b) to require hand lines to have a diameter of between 12 and 20 mm 
and a minimum length of 35 m with uniform thickness throughout to avoid 
jamming on the car haulers and bollards that has occurred because of 
splicing of uneven pieces.
    Section 401.26, ``Security for tolls'', is amended by revising 
paragraph (d) to reduce the security required where a number of 
vessels, for each of which a preclearance application has been 
approved, are owned or controlled by the same individual or company and 
have the same representative. Security for tolls for these vessels is 
not required if every toll account received in the preceding five years 
has been paid within forty-five days after the vessel enters the 
Seaway.
    Section 401.42, ``Passing hand lines'', is amended by revising 
paragraph (a)(1) to change ``linesmen'' to ``linehandlers'' for gender 
neutrality.
    Section 401.43, ``Mooring table'', is amended by deleting the 
unnecessary references to specific locations for simplification.
    Section 401.45, ``Emergency procedure'', is amended to requiring 
the Master to be responsible for giving the signal in an emergency upon 
entering the locks to make the practice consistent in both Canadian and 
U.S. locks and, for safety purposes, by requiring mooring lines to be 
put out as quickly as possible.
    Section 401.52, ``Limited of approach to a bridge'', is amended by 
revising paragraph (b) to change ``Caughnawaga'' to Kahnawake'', as it 
is now commonly known.
    Section 401.64, ``Calling in'', is amended by revising paragraph 
(e) to make the master solely responsible because it is his or her, not 
the pilot's responsibility.
    Section 401.65, ``Communication--ports, docks, and anchorages'', is 
amended by revising paragraph (a)(1) to round off 0.87 of a nautical 
mile to 1 nautical mile for simplification and by removing that part of 
paragraph (c) that refers to dangerous cargo reporting and placing its 
substance in Sec. 401.66, which is a more appropriate location.
    Section 401.66, ``Applicable laws'', is amended by redesignating 
the current text as paragraph (a) and adding a new paragraph (b), which 
is the text removed from Sec. 401.65(c) amended to change the dangerous 
cargo reporting and filing requirements to reflect the practice 
instituted by the Canadian Authority under Seaway Notice No. 2 of 1993.
    Section 401.71, ``Signals--explosive or hazardous cargo vessels'', 
is amended by deleting paragraph (b) and revising current paragraph (a) 
to combine the requirements for explosive and hazardous vessels into 
one to be consistent with the international collision regulations.
    Section 401.72, ``Reporting--explosive and hazardous cargo 
vessels'', is amended by adding new paragraphs (e), (f), (g), and (h) 
to require certain information on load plans concerning dangerous cargo 
to ensure enhanced safety, reflecting the practice instituted by the 
Authority under Seaway Notice No. 2 of 1993. In response to a comment 
received by the Authority, the reference to ``IMO'' in subsection 
(e)(1) is changed to ``IMDG'', which is the correct designation for the 
International Dangerous Goods Code.
    Subsection (g) is also changed in response to a comment received by 
the Authority. This change covers the situation where an actual 
Material Safety Data sheet for a cargo carried by a vessel is not on 
file with a Seaway Traffic Control Center, but the vessel carries 
sufficient information for its preparation. Either form of compliance 
will allow the vessel to continue transit through the system.
    Section 401.75, ``Payment of tolls'', is amended to provide that 
every toll invoice shall be paid in Canadian or American funds within 
forty-five days after the vessel enters the Seaway and any adjustment 
of the amount payable shall be provided for in a subsequent invoice, 
which is consistent with the new policy on reduced security in revised 
Sec. 401.26(d). To be consistent with the text of the Canadian version 
of these joint regulations, this revised Sec. 401.75 text is 
redesignated as paragraph (a) and the current Sec. 401.77 is 
redesignated as paragraph (b) of Sec. 401.75 and revised by making non-
substantive editorial changes.
    Section 401.84, ``Reporting of impairment or other hazard by 
vessels transiting within the Seaway'', is amended by revising 
paragraph (c) to reflect that the reporting requirements cover the 
equipment listed in Schedule I as well.
    Section 401.89, ``Transit refused'', is amended by revising 
paragraph (a)(1) to transit refusal may be based upon the equipment 
requirements in Schedule I as well when transiting Canadian waters.
    Section 401.91, ``Removal of obstructions'', is amended to remove 
the words ``take such action * * * as the Corporation or the Authority 
deem necessary'' as superfluous.
    Section 401.94, ``Keeping copy of regulations'', is amended to 
require that, in addition to a copy of the Regulations, a copy of the 
vessel's latest Ship Inspection Report, and Seaway Notices for the 
navigation year shall be kept on board each vessel, which reflects the 
routine requirement for this documentation for inspection and reference 
purposes.
    Schedule I, ``VESSELS TRANSITING U.S. WATERS'', is amended by 
revising paragraph (d)(3) to require, for each vessel with a fixed 
propeller, a table of shaft revolutions per minute, for a 
representative range of speeds, and a notice showing any critical range 
of revolutions at which the engine

[[Page 19550]]

designers recommend that the engine not be operated on a continuous 
basis because this information is necessary for officers or pilots 
having conduct of the vessel.
    It was proposed to amend Schedule II, ``Table of Speeds'', by 
revising item 4 to reduce the allowable speeds in the area covered, by 
revising item 6 to reduce the allowable speeds in the area covered and 
include the areas that have been covered by items 7 through 10 under 
item 6's allowable speed limits to eliminate varying speed areas, 
reduce speeding violations, and reduce vessel wake damages. Items 7 
through 10 were to be removed and items 11 through 15 renumbered 
accordingly. Two comments, both from pilots, objected on the basis that 
it would increase transit time and thus increase pilot fatigue and 
stress, resulting in a decrease in the safety margin. They also stated 
that proffering wake damage as a basis for the change in all areas was 
unfounded. The Corporation and the Authority agree only in part. The 
Table of Speeds will now be amended as follows. The speed limit from 
Eisenhower to Iroquois Lock will be set at 11.5 knots. Presently, the 
limits for this section are divided into four separate speed zones: 
11.5 knots from Eisenhower to Richard's Point Light #55 (5.34 nautical 
miles); 13.0 knots from Richards Point Light #55 to Doran Shoal Buoy 84 
(9.08 nautical miles); 11.5 knots from Doran Shoal Buoy 84 to Ogden 
Island Buoy 99 (4.24 nautical miles); and 13.0 knots from Ogden Island 
Buoy 99 to Iroquois Lock (3.54 nautical miles). The speed limit between 
Richards Point and Doran Shoal will be reduced to 11.5 knots. This 
increases transit time by 5.5 minutes, not allowing for the time 
required to speed up or slow down in the original 13.0 knot zone. The 
speed limit from Buoy 99 to Iroquois Lock will be changed to 11.5 
knots, which will have a negligible effect on transit time. This is a 
short area where a ship must be checked down before unbound entry into 
the lock or starting from rest while downbound in the lock with 
checking down required before entering the reduced speed area. The 11.5 
knot speed zone presently in effect from \1/2\ mile east of Buoy 162 to 
Light 186 will be extended to include the area between McNair Island 
Light 137 to Light 186. This extends the 11.5 knot zone eastward by 
8.32 nautical miles and increases transit time by 5 minutes. The 
section from Iroquois Lock to McNair Island would remain at 13.0 knots. 
This change results in a lower speed limit for the Brockville Narrows, 
for which there have been numerous complaints and significant safety 
concerns because of large ship wakes in close proximity to pleasure and 
tour boats. Overall, these changes increase transit time in the Snell 
Lock to Cape Vincent pilotage area by only 10.5 minutes, which should 
have no real effect on pilot stress and fatigue, while reducing safety 
and wake concerns in the Brockville Narrows, Mariatown, and Wilson Hill 
areas. The change from the original proposal is that, instead of 
maintaining an 11.5 knot limit from Eisenhower Lock to Light 186, a 
13.0 knot zone will be retained through the Prescott anchorage, where 
traditionally vessels have the opportunity to overtake. The Corporation 
and the Authority believe that these changes are prudent and are 
justified by experience and observation. Speed limits traditionally are 
set to protect the shoreline, Seaway channels, and the boating public 
from damage or injury. Wake complaints are logged and vessel speed spot 
checks are made from shore positions, with the draw down and surge of 
each observed vessel measured and recorded. The Authority alone carried 
out approximately 875 speed checks in 1995. Speed limits are the best 
tool for controlling damaging wake by setting a standard for the 
navigation team on each vessel to follow.
    Appendix I, ``Vessel Dimensions'', is amended by revising the 
second undesignated paragraph after paragraph (b) to round off ``23.16 
m'' to ``23.2 m'' for simplication and conformity with the amendment to 
Sec. 401.3.
    There are some minor editorial changes to conform with the SLSA 
version approved under the Canadian regulatory review process that do 
not have any substantive impact, such as changing the word ``upon'' to 
``on'' in Sec. 401.3(e)(1).

Regulatory Evaluation

    This final rule inolves a foreign affairs function of the United 
States, and therefore, Executive Order 12866 does not apply. This final 
rule has also been evaluated under the Department of Transportation's 
Regulatory Policies and Procedures and the proposed regulation is not 
considered significant under those procedures and its economic impact 
is expected to be so minimal that a full economic evalaution is not 
warranted.

Regulatory Flexibility Act Determination

    The Saint Lawrence Seaway Development Corporation certifies that 
this final rule will not have a significant economic impact on a 
substantial number of small entities. The St. Lawrence Seaway 
Regulations and Rules primarily relate to the activities of commercial 
users of the Seaway, the vast majority of whom are foreign vessel 
operators. Therefore, any resulting costs will be borne mostly by 
foreign vessels.

Environmental Impact

    This final rule does not require an environmental impact statement 
under the National Environmental Policy Act (49 U.S.C. 4321, et seq.) 
because it is not a major federal action significantly affecting the 
quality of human environment.

Federalism

    The Corporation has analyzed this final rule under the principles 
and criteria in Executive Order 12612 and has determined that this 
final rule does not have sufficient federalism implicaitons to warrant 
the preparation of a Federalism Assessment.
