Endangered and Threatened Wildlife; Sea Turtle Conservation

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and
Atmospheric Administration (NOAA), Commerce.
ACTION: Proposed rule; request for comments.

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

SUMMARY: The National Marine Fisheries Service (NMFS) currently
requires the use of chain-mat modified dredge gear in the Atlantic sea
scallop fishery south of 41[deg]9.0' North latitude from May 1 through
November 30 each year. This gear is necessary to help reduce mortality
and injury to endangered and threatened sea turtles captured in this
fishery and to conserve sea turtles listed under the Endangered Species
Act (ESA). This proposed action would make minor modifications to the
current requirements by clarifying where on the dredge the chain mat
should be hung; by excluding the sweep from the requirement that the
side of each opening in the chain mat be less than or equal to 14
inches (35.5 cm); and by adding definitions of the sweep and the
diamonds, which are terms used to describe parts of the scallop dredge
gear. Any incidental take of threatened sea turtles in Atlantic sea
scallop dredge gear in compliance with the gear modification
requirements and all other applicable requirements will be exempted
from the ESA prohibition against takes. NMFS is requesting public
comment on this action, the focus of which is the minor modifications
described here. NMFS is not accepting public comment on the existing
chain mat requirements through this proposed rule.

DATES: Comments on the proposed rule must be received by 5 p.m. EST on
June 4, 2009.

SUPPLEMENTARY INFORMATION:

Background

    All sea turtles that occur in U.S. waters are listed as either
endangered or threatened under the Endangered Species Act of 1973
(ESA). The Kemp's ridley (Lepidochelys kempii), leatherback
(Dermochelys coriacea), and hawksbill (Eretmochelys imbricata) sea
turtles are listed as endangered. The loggerhead (Caretta caretta) and
green (Chelonia mydas) sea turtles are listed as threatened, except for
breeding populations of green turtles in Florida and on the Pacific
coast of Mexico that are listed as endangered. Kemp's ridley, hawksbill,
loggerhead, and green sea turtles are hard-shelled sea turtles.
    Under the ESA and its implementing regulations, taking sea turtles
under NMFS's jurisdiction, even incidentally, is prohibited, with
exceptions identified at 50 CFR 223.206. The incidental take, both
lethal and non-lethal, of loggerhead, Kemp's ridley, and unidentified
hard-shelled sea turtles as a result of scallop dredging has been
observed in the Atlantic sea scallop fishery (Northeast Fisheries
Science Center (NEFSC) Fisheries Sampling Branch (FSB), Observer
Database). In addition, a non-lethal take of a green sea turtle has
been observed in this fishery (NEFSC FSB, Observer Database) and one
unconfirmed take of a leatherback sea turtle was reported during the
experimental fishery to test the chain-mat modified gear (DuPaul et
al., 2004).
    Sea turtles caught in scallop dredge gear often suffer injuries.
The most commonly observed injury is damage to the carapace. The exact
causes of these injuries are unknown, but most likely appear to be from
being struck by the

[[Page 20668]]

dredge (during a tow or upon emptying of the dredge bag on deck),
crushed by debris (e.g., large rocks) that collects in the dredge bag,
or as a result of a fall during hauling of the dredge. The chain mat is
a grid of horizontal and vertical chains hung over the mouth of the
dredge bag to prevent sea turtles from entering the bag and to prevent
injury and mortality that results from such capture (i.e., due to
debris in the bag, a fall while emptying the bag, or dropping of the
gear on the catch). A full description of the chain mat and the
benefits to sea turtles can be found in the proposed and final rules
implementing the regulations (72 FR 63537, November 9, 2007; 73 FR 18984,
April 8, 2008) and the associated Environmental Assessment (NMFS 2008).
    In 2008, an image analysis that calculated the length of the sides
of the openings created by the intersecting horizontal and vertical
chains for an 11-ft. chain-mat equipped dredge was completed. Only a
single photograph was analyzed in this analysis. The analysis showed
that the lengths of the sides of the openings were both greater than
and less than 14 inches and that 14 inches was within the range of
openings tested in the experimental fishery. Based on this information,
NMFS re-evaluated the chain mat requirements and the analysis conducted
for the April 2008 rule. NMFS found that the available information
continues to support an opening of 14 inches or less and that the conclusions
of the analysis conducted for the April 2008 rule are still valid.
    This proposed rule would modify the existing chain mat regulations
that apply to chain-mat modified dredges in the Atlantic sea scallop
fishery. This proposed rule, if implemented, would (1) more clearly
define where on the dredge gear the chain mat must be hung; (2) exclude
the sweep from the requirement that each side of the opening must be 14
inches (35.5 cm) or less; and (3) define the ``sweep'' and the
``diamonds'', which are terms used to describe parts of the scallop
dredge gear. This rule is being proposed under the ESA provisions
authorizing the issuance of regulations to conserve threatened species
and for enforcement purposes (sections 4(d) and 11(f), respectively).

Configuration of the Gear

    The current regulations define a chain mat as ``* * * a device
designed to be installed in a scallop dredge forward of the sweep, as
described in 50 CFR 223.206, for the purpose of excluding sea turtles
from the dredge.'' The regulations at 50 CFR 223.206 state, in part,
that ``During the time period of May 1 through November 30, any vessel
with a sea scallop dredge and required to have a Federal Atlantic sea
scallop fishery permit, regardless of dredge size or vessel permit
category, that enters waters south of 41[deg]9.0' N. latitude, from the
shoreline to the outer boundary of the Exclusive Economic Zone must
have on each dredge a chain mat described as follows. The chain mat
must be composed of horizontal (``tickler'') chains and vertical (up-
and-down) chains that are configured such that the openings formed by
the intersecting chains have no more than 4 sides. The length of each
side of the openings formed by the intersecting chains, including the
sweep, must be less than or equal to 14 inches (35.5 cm).'' NMFS has
determined that ``forward of the sweep'' does not fully describe the
configuration and that more specificity would ensure that the
requirements are met consistently in the manner NMFS intends.
Therefore, this proposed rule would clarify that the chain mat must
cover the entire opening of the dredge bag by specifying that ``The
vertical and horizontal chains must be hung to cover the opening of the
dredge bag such that the vertical chains extend from the back of the
cutting bar to the sweep. The horizontal chains must intersect the
vertical chains such that the length of each side of the openings
formed by the intersecting chains is less than or equal to 14 inches
(35.5 cm) * * *'' These changes simply clarify the existing
requirements and would not result in any additional or different
biological, physical, or socio-economic impacts.

Exclusion of the Sweep

    Second, NMFS proposes to exclude the sweep from the requirement
that each side of the openings formed by the intersecting chains be
less than or equal to 14 inches (35.5 cm). For those openings adjacent
to the sweep, the sweep chain will create one side of the opening.
Under the current requirements, the length of the side created by the
sweep chain must be 14 inches (35.5 cm) or less. However, NMFS has re-
examined this requirement and has found that except in rare cases, the
size of the openings along the sweep will be smaller (even if the
length of the side created by the sweep exceeds 14 inches (35.5 cm))
than the size of the openings created by a square with 14 inches (35.5
cm) per side, the maximum opening allowed throughout the chain mat.
Given the configuration of the dredge gear, it is possible that one
opening at the bottom of the arc created by the sweep could be greater
than the opening created by a square with 14 inches (35.5 cm) per side
if the vertical chains forming the two sides of this opening were at or
near 14 inches (35.5 cm) in length.
    There are several reasons why this proposed change would result in
inconsequential impacts on the conservation benefit of the chain mats.
First, along the sweep, the openings are irregularly shaped and may be
three- or four-sided (see EA for figure), generally resulting in a
smaller opening than throughout the rest of the chain mat. Given the
configuration of the gear and the area of the openings along the sweep,
the number of openings that may be larger than the opening created by a
square with 14 inches (35.5 cm) per side is limited to a single opening
in the chain mat. Second, the increase in size of the one opening is
only a small fraction of the size of the openings allowed throughout
the chain mat due to the arc in the sweep. This increase is further
limited by the fact that the sweep chain is generally a heavier chain,
which would take up some of the space within the opening. Third, this
slightly larger opening would only be present on a subset of the
dredges used in the fishery and, where present on a dredge, would be
limited to only one of the chain mat openings. In some cases, fishermen
are configuring the gear such that the sides of the openings created by
the intersecting chains are less than 14 inches (35.5 cm) to allow for
chain stretch and wear. In these cases, the opening at the bottom of
the arc created by the sweep would likely be smaller than that created
by a square with 14 inches (35.5 cm) per side, and all of the openings
in the chain mat would be consistent with the openings allowed under
the current regulations.
    Given that the slightly larger opening is limited to one opening on
a subset of the dredges used in the fishery and that the increase in
the size of the opening is small due to the way the gear is configured,
the conservation benefit to sea turtles under this requirement is
essentially the same as the current requirements. While possible, it is
highly unlikely that a sea turtle that would be excluded by a square
with 14 inches (35.5 cm) per side would encounter and pass through the
one slightly larger opening that may be present on some dredges.
    Chain mats are currently required in certain areas and times. This
rule would not change the spatial or temporal extent of the
requirements. It would make minor modifications to how the gear is
configured. However, given that the modifications are minor and that
the gear would continue to be required in the same areas and times,
this action

[[Page 20669]]

would not result in any additional impacts to the physical environment
or to habitat. This change would also not result in any additional
economic costs (see Classification section).

Definition of the Sweep and the Diamonds

    As the modifications above specifically exclude the sweep from the
requirement that the openings in the chain mat be 14 inches (35.5 cm)
per side, NMFS would add a definition of the sweep to the regulations.
NMFS is proposing to define the sweep as ``A chain extending, usually
in an arc, from one end of the dredge frame to the other to which the
ring bag, including the diamonds, is attached. The sweep forms the edge
of the opening of the dredge bag.'' NMFS would also add a definition of
the ``diamonds'' to the regulations. NMFS is proposing to define the
diamonds as ``the triangular shaped portions of the ring bag on the
`dredge bottom' as defined at 50 CFR 648.2.'' This definition is
necessary as the term diamonds is used to define the sweep.

Classification

    This proposed rule has been determined to be not significant for
purposes of Executive Order 12866. A description of the action, why it
is being considered, and the legal basis for this action are contained
in the preamble. No reporting, recordkeeping, or other compliance
requirements are proposed. No duplicative, overlapping, or conflicting
Federal rules have been identified.
    The Chief Counsel for Regulation of the Department of Commerce
certified to the Chief Counsel for Advocacy of the Small Business
Administration that this proposed rule, if adopted, would not have a
significant economic impact on a substantial number of small entities.
As a result, an initial regulatory flexibility analysis is not required
and none has been prepared.
    The small entities affected by the chain mat regulations are
Atlantic sea scallop fishermen entering waters south of 41[deg] 9.0' N.
latitude from the shoreline to the outer boundary of the Exclusive
Economic Zone. These regulations apply to all vessels with a sea
scallop dredge(s) and required to have a Federal Atlantic sea scallop
fishery permit, regardless of the dredge size or vessel permit category.
    The final rule (73 FR 18984, April 8, 2008) and Final Environmental
Assessment/Final Regulatory Flexibility Act Analysis/Regulatory Impact
Review (EA/FRFA/RIR) (NMFS 2008) implementing the chain-mat modified
dredge requirements identified 314 vessels that would be affected by
the chain mat requirements. The economic impacts of the minor changes
proposed here are described below.
    Under the current requirements, the length of each side of the
opening created by the intersecting chains, including the side created
by the sweep chain, must be 14 inches (35.5 cm) or less. NMFS has
identified two alternate ways to configure the gear to comply with the
regulation as currently written. Fishermen could create smaller
openings (approximately 9-10 inches (27.9-25.4 cm) per side) throughout
the mat to ensure that the length of the side created by the sweep was
less than or equal to 14 inches (35.5 cm). However, it was never the
intention that the requirement result in openings in the chain mat of
9-10 inches (27.9-25.4 cm) per side. Alternatively, fishermen could add
a small piece of chain to any opening where the length of the side
created by the sweep is greater than 14 inches (35.5 cm). The number of
openings that would require a piece of additional chain is expected to
be limited to that area along the sweep that is curved. This short
piece of chain would divide the sweep, creating two smaller openings.
The pieces of chain would be no more than 14 inches (35.5 cm), and in
many cases, the segments are likely to be much less than 14 inches
(35.5 cm). As described in the EA (NMFS 2008) for the final rule (73 FR
18984, April 8, 2008) requiring the use of chain-mat modified dredge
gear, a 15-ft (4.57-m) dredge with frame, bag, and club stick weighs
approximately 4500 pounds (2041 kg). The weight of the chain mat was
estimated to be between 67 pounds (30.1 kg) for a 10-ft (3.05-m) dredge
and 176 pounds (79.8 kg) for a 15-ft (4.57-m) dredge (NMFS 2008). In
the economic analysis for the 2008 regulations, a conservative estimate
(20 percent) of the additional chain required to comply with the 14-
inch (35.5-cm) requirement was used. Therefore, it is likely that the
costs of these additional small segments were subsumed in that
analysis. However, some additional information on the amount of chain
required to divide these openings is provided here. The estimated cost
for the chain was $2.00 to $3.00 per foot. Therefore, given that the
additional chain required is only a short segment added to a limited
number of openings, it is expected that the economic costs would be
minimal. This amount of chain is also not expected to affect the weight
of the gear or its efficiency.
    The proposed action would not result in any additional costs, and,
under this action, the vessel would not incur the costs associated with
adding small lengths of additional chain to ensure that the sweep
segments do not exceed 14 inches (35.5 cm). Therefore, the differences
in cost between a chain mat configured under the current requirements
and one configured as proposed here are minimal. This action would not
affect the profitability of the vessel. As this action is not expected
to result in any additional costs or to affect the profitability of the
vessel, it will not contribute to cumulative economic impacts.
    With the exception of the rare cases described in the preamble, the
size of the openings along the sweep will be smaller (even if the
length of the side created by the sweep exceeds 14 inches (35.5 cm))
than the size of the openings created by a square with 14 inches (35.5
cm) per side, the maximum opening allowed throughout the chain mat.
Therefore, the proposed action would only result in inconsequential
impacts on the conservation benefit of the chain mats (see preamble).
In addition, the clarification as to the configuration of the gear and
the additional definitions would not result in any socio-economic impacts.
