SUPPLEMENTARY INFORMATION:
Previous Federal Actions
On October 4, 2017, we published a
proposed rule in the Federal Register
(82 FR 46183) to list the trispot darter
as a threatened species under the Act
(16 U.S.C. 1531 et seq.). Please refer to
that proposed rule for a detailed
description of previous Federal actions
concerning this species.
Elsewhere in today’s Federal Register,
we propose to (1) designate critical
habitat for the trispot darter under the
Act; and (2) issue a rule under section
4(d) of the Act that provides measures
necessary and advisable for the
conservation of the trispot darter.
Background
Please refer to the October 4, 2017,
proposed rule (82 FR 46183) and the
Species Status Assessment (SSA) Report
for a full summary of species
information. Both documents are
available at https://www.regulations.gov
under Docket No. FWS–R4–ES–2017–
0063, and on the Service’s Southeast
Region website at https://www.fws.gov/

The trispot darter is a freshwater fish
found in the Coosa River System in the
Ridge and Valley ecoregion of Alabama,
Georgia, and Tennessee. This fish has a
historical range from the middle to
upper Coosa River Basin with
collections in the mainstem Coosa,
Oostanaula, Conasauga, and
Coosawattee Rivers, and their
tributaries. Currently, the trispot darter

is known to occur in four populations
in the Little Canoe Creek and tributaries
(Coosa River), Ballplay Creek tributaries
(Coosa River), Conasauga River and
tributaries, and Coosawattee River and
one tributary.
The trispot darter is a migratory
species that utilizes distinct breeding
and non-breeding habitats. From
approximately April to October, the
species inhabits its non-breeding
habitat, which consists of small to
medium river margins and lower
reaches of tributaries with slower
velocities. It is associated with detritus,
logs, and stands of water willow, and
the substrate consists of small cobbles,
pebbles, gravel, and often a fine layer of
silt. During low flow periods, the darters
move away from the peripheral zones
and toward the main channel; edges of
water willow beds, riffles, and pools;
and mouths of tributaries. In late fall,
this migratory species shifts its habitat
preference and begins movement toward
spawning areas; this is most likely
stimulated by precipitation, but
temperature changes and decreasing
daylight hours may also provide cues to
begin migration. Migration into
spawning areas begins approximately
late November or early December with
fish moving from the main channels
into tributaries and eventually reaching
adjacent seepage areas where they will
congregate and remain for the duration
of spawning, approximately until late
April. Breeding sites are intermittent
seepage areas and ditches with little to
no flow; shallow depths (12 inches (30
centimeters) or less); moderate leaf litter
covering mixed cobble, gravel, sand,
and clay; a deep layer of soft silt over
clay; and emergent vegetation. Trispot
darters predominantly feed on mayfly
nymphs and midge larvae and pupae.
The trispot darter was first described
in 1963 from a single specimen
collected in Cowans Creek in Cherokee
County, Alabama. This species was
originally described as a member of the
E:\FR\FM\28DER1.SGM

subgenus Psychromaster and was later
moved to the subgenus Ozarka in 1980
where it remains today. Currently, the
trispot darter is considered a valid taxon
(Service 2017, p. 6).

Summary of Comments and
Recommendations
In our October 4, 2017, proposed rule
to list the trispot darter as a threatened
species (82 FR 46183), we requested that
all interested parties submit written
comments on the proposal by December
4, 2017. We also contacted appropriate
Federal and State agencies, scientific
experts and organizations, and other
interested parties, and invited them to
comment on the proposal. Newspaper
notices inviting general public comment
were published in the St. Clair NewsAegis, St. Clair Times, Chattanooga
Times Free Press, Atlanta Journal
Constitution, and The Daily Home. We
did not receive any requests for a public
hearing. All substantive information
provided during the comment period
has either been incorporated directly
into this final determination or is
addressed, by topic, below.
Peer Reviewer Comments
In accordance with our peer review
policy published on July 1, 1994 (59 FR
34270), and our August 22, 2016,
memorandum updating and clarifying
the role of peer review actions under the
Act, we solicited expert opinion from
four knowledgeable individuals with
scientific expertise that included
familiarity with trispot darter and its
habitat, biological needs, and threats.
We received responses from two of the
peer reviewers.
We reviewed all comments we
received from the peer reviewers for
substantive issues and new information
regarding the information contained in
the SSA Report. The peer reviewers
generally concurred with our methods
and conclusions, and provided
additional information, clarifications,
and suggestions to improve the final
SSA Report. Peer reviewer comments
are addressed in the following summary
and were incorporated into the final
SSA Report as appropriate.
(1) Comment: One peer reviewer
expressed doubt that hurricanes or other
large storms can negatively affect stream
fish communities.
Our Response: Large storms have been
found to disturb aquatic habitats to the
extent that stream fish assemblages have
been observed to be altered as a result
(Service 2017, p. 25; Service 2011, p. 9).
Recovery of stream fish communities to
assemblages seen before disturbances
from large storms depends on adjacent
source populations and the dispersal
VerDate Sep<11>2014
16:02 Dec 27, 2018
Jkt 247001
ability of specific species. In the case of
rare species with isolated populations
such as the trispot darter, large storms
that are capable of causing a level of
disturbance that alters fish communities
can pose a substantial threat. A more
thorough discussion of this threat can be
found in the SSA Report (Service 2017,
p. 25).
(2) Comment: One peer reviewer
suggested that not enough information
was available on the trispot darter to
infer its historical range.
Our Response: We are required to use
the best available commercial and
scientific information available at the
time we make our determination.
Available resources at the time of
rulemaking have described the range of
the trispot darter as the upper Coosa
River system. Based on recorded
occurrences of the trispot darter in the
mainstem of the Coosa River and
tributaries to the Coosa River in
Alabama, Georgia, and Tennessee, we
conclude that the historical range
described as the upper Coosa River
system is reasonably supported.
Public Comments
(3) Comment: One commenter
expressed concern about the presence of
the Conasauga Shale Field, a natural
gas-bearing formation, within portions
of the trispot darter’s range. The
commenter provided current research
that demonstrated negative associations
between hydraulic fracturing (fracking)
and fish recruitment, and recommended
the Service evaluate oil and gas
exploration in the Conasauga Shale
Field and its influence on trispot darter.
Our Response: We contacted the
Alabama State Oil and Gas Board to
assess the current and future status of
natural gas exploration and exploitation
of the Conasauga Shale Field in
Alabama. Based on our correspondence,
we find that fracking within the
Conasauga Shale Field is unlikely to be
a threat to the trispot darter within the
foreseeable future. Currently, no new
drilling permits have been approved,
and all existing wells have been plugged
and abandoned. Wells were abandoned
due to low productivity and low gas
prices. For these reasons, and because of
low permeability of the rock formation,
the Alabama State Oil and Gas Board
expects that oil and gas extraction is
unlikely to occur there within the
foreseeable future.
(4) Comment: One commenter
provided additional information on the
effects of hypolimnetic releases from
dams on riverine ecosystems and fish
species present in tailwaters.
Hypolimnetic refers to the part of a lake
below the thermocline made up of water
PO 00000
Frm 00100
Fmt 4700
Sfmt 4700
that is stagnant and of essentially
uniform temperature except during the
period of overturn. The commenter also
noted that dams can create many
kilometers of unsuitable habitat because
of changes in the temperature regime
from hypolimnetic flow releases.
Decreases in streamflow temperature as
a result of hypolimnetic releases have
been shown to adversely affect darter
species by increasing the probability of
local extinction in cold waters
downstream of dams.
Our Response: We incorporated the
information from the additional studies
clarifying the effects of hydropower
projects on aquatic species and have
added them to the appropriate sections
of the SSA Report. We also recognize
that currently the trispot darter is
exposed to releases from the Carters
Reregulation Dam. However, past
research has found that operation of the
reregulation dam does not affect the
system’s ability to provide adequate
dissolved oxygen for the trispot darter
(Freeman 2011, p. 10); this system also
still meets State water quality and
temperature standards (USACE 2015, p.
4–13). Therefore, temperature and
dissolved oxygen alterations are not
viewed as stressors to the trispot darter
in the Coosawattee River below the
Carters Reregulation Dam.
(5) Comment: One commenter noted
that the overall condition of the Little
Canoe Creek Management Unit (MU) is
ranked as moderate even though six of
the seven factors considered in the
ranking scored as ‘‘low’’ in the October
4, 2017, proposed rule to list the trispot
darter as a threatened species (82 FR
46183).
Our Response: The overall condition
for the Little Canoe Creek MU presented
in the proposed rule (see 82 FR 46187)
and the SSA Report (version 1.0) was in
error. We have corrected the condition
rank in this rule and the updated SSA
Report (version 1.2). However, this
correction does not change our
assessment of future conditions in the
SSA Report, nor our conclusions
presented in the October 4, 2017,
proposed rule.
Summary of Changes From the
Proposed Rule
In preparing this final rule, we
reviewed and fully considered
comments from the public on the
proposed rule. We did not make any
substantive changes to this final rule
after consideration of the comments we
received. We did update the SSA Report
(to version 1.2) based on comments and
some additional information provided,
as follows: (1) We made many small,
nonsubstantive clarifications and
E:\FR\FM\28DER1.SGM
28DER1
Federal Register / Vol. 83, No. 248 / Friday, December 28, 2018 / Rules and Regulations

corrections throughout the SSA Report,
including ensuring consistency of colors
on maps, providing details about data
sources used, updating references, and
making minor clarifications; and (2) we
included in the updated version of the
SSA Report the additional information
we received regarding observations of
the trispot darter, hypothesized
historical range of the trispot darter, and
more detailed life-history data for the
species. However, the information we
received during the comment period for
the proposed rule did not change our
determination that the trispot darter is
a threatened species.
Summary of Biological Status and
Threats
Section 4 of the Act (16 U.S.C. 1533),
and its implementing regulations in title
50 of the Code of Federal Regulations at
50 CFR part 424, set forth the
procedures for adding species to the
Federal Lists of Endangered and
Threatened Wildlife and Plants. Under
section 4(a)(1) of the Act, we may list a
species based on (A) the present or
threatened destruction, modification, or
curtailment of its habitat or range; (B)
overutilization for commercial,
recreational, scientific, or educational
purposes; (C) disease or predation; (D)
the inadequacy of existing regulatory
mechanisms; or (E) other natural or
manmade factors affecting its continued
existence. These factors represent broad
categories of natural or human-caused
actions or conditions that could have an
effect on a species’ continued existence.
In evaluating these actions and
conditions, we look for those that may
have a negative effect on individuals of
the species, as well as other actions or
conditions that may ameliorate any
negative effects or may have positive
effects.
We use the term ‘‘threat’’ to refer in
general to actions or conditions that are
known to or are reasonably likely to
negatively affect individuals of a
species. The term ‘‘threat’’ includes
actions or conditions that have a direct
impact on individuals (direct impacts),
as well as those that affect individuals
through alteration of their habitat or
required resources (stressors). The term
‘‘threat’’ may encompass—either
together or separately—the source of the
action or condition or the action or
condition itself. However, the mere
identification of any threat(s) does not
necessarily mean that the species meets
the statutory definition of an
‘‘endangered species’’ or a ‘‘threatened
species.’’ In determining whether a
species meets either definition, we must
evaluate all identified threats by
considering the expected response by
VerDate Sep<11>2014
16:02 Dec 27, 2018
Jkt 247001
the species, and the effects of the
threats—in light of those actions and
conditions that will ameliorate the
threats—on an individual, population,
and species level. We evaluate each
threat and its expected effects on the
species, then analyze the cumulative
effect of all of the threats on the species
as a whole. We also consider the
cumulative effect of the threats in light
of those actions and conditions that will
have positive effects on the species—
such as any existing regulatory
mechanisms or conservation efforts. The
Secretary determines whether the
species meets the definition of an
‘‘endangered species’’ or a ‘‘threatened
species’’ only after conducting this
cumulative analysis and describing the
expected effect on the species now and
in the foreseeable future.
Our assessment evaluated the
biological status of the species and
threats affecting its continued existence.
It was based upon the best available
scientific and commercial data,
including the SSA Report (Service 2018,
entire), and the expert opinion of the
SSA team members. Please refer to
chapter 3 of the SSA Report (Service
2018, pp. 17–25) for a more detailed
discussion of the factors affecting the
trispot darter.
Risk Factors Influencing Viability of
Trispot Darter
As discussed above, we considered
the five factors set forth in section
4(a)(1) of the Act in assessing whether
the species meets the definition of an
endangered or a threatened species. A
multitude of natural and anthropogenic
factors may impact the status of species
within aquatic systems. The largest
threats to the future viability of the
trispot darter involve habitat
degradation from factors influencing
four habitat elements: Water quality,
water quantity, instream habitat, and
habitat connectivity (Factor A). All of
these factors are exacerbated by the
effects of climate change (Factor E). A
brief summary of these primary stressors
is presented below; for a full description
of the factors, refer to chapter 4 of the
SSA Report.
Hydrologic Alteration
Activities that lead to hydrologic
alteration include reservoir construction
and operation, excessive water
withdrawals, and an increase in
impervious surfaces.
Hydrologic alteration in the system
occupied by the trispot darter has two
components: Increases in storm flow
frequency and intensity, and a decrease
in base flows, which together create a
‘‘flashy’’ hydrologic regime. In a natural
PO 00000
Frm 00101
Fmt 4700
Sfmt 4700
67133
forested system, most rainfall soaks into
the soil and is carried into nearby
streams via subsurface flow. Some
evaporates or transpires, and a relatively
small amount becomes surface runoff. In
the trispot darter’s system, which is
urbanized with large amounts of
impervious cover such as roads, parking
lots, and rooftops, this cycle is altered;
most stormwater hits impervious
surfaces and becomes runoff, which
then is channeled quickly to streams via
stormwater drain pipes or ditches.
Relatively little infiltrates into the soil.
As a result, storm flows in the receiving
stream are higher and more frequent,
although briefer in duration, and base
flows are lower, than in natural systems.
The storm discharge of urban streams
can be twice that of rural streams
draining a watershed of similar size, and
the frequency of channel-forming events
can be 10 times that of pre-development
conditions. These ‘‘flashy’’ stream flows
and frequent, smaller high-flow events
negatively affect structural habitat on
which the trispot darter depends.
Increases in flow frequency or intensity
can result in channel widening through
bank erosion or deepening to
accommodate the additional discharge.
This results in increased downstream
sedimentation and unstable beds, both
of which degrade channel complexity
and feeding and refugia habitat for fish
species. Increased storm flows, in
addition, can cause physical washout of
eggs and larval fishes, stress on adults,
and negatively alter the stream’s food
web, affecting many fish species. There
is also a decrease in channel complexity
and a reduction in instream cover and
natural substrates like boulders, cobble,
and gravel.
Reservoirs can substantially alter
hydrology downstream, especially when
operated for hydroelectric power
generation. Hydropeaking dams produce
high flows only when power generation
is needed. Hydropeaking dams, Carters
Dam and Reregulation Dam, exist on the
Coosawattee River. Rapid flow increases
and decreases from hydropeaking can
reduce stream insect abundance,
potentially decreasing food availability
for darters. Furthermore, managed rivers
can exhibit substantially altered and
novel food webs that affect native
communities and their ability to
withstand perturbations. Nonhydropeaking reservoirs, farm ponds,
amenity lakes, and other impoundments
may also substantially alter hydrologic
regimes by storing water during low
flow periods, effectively dampening
moderate to high flows and in some
cases augmenting flows. Fish are
adapted to the natural seasonal
E:\FR\FM\28DER1.SGM
28DER1
67134
Federal Register / Vol. 83, No. 248 / Friday, December 28, 2018 / Rules and Regulations
variations of flow, and alterations to this
regime affect their life-history strategies.
Hydrologic alteration can also lead to
other stressors, such as sedimentation
and a loss of connected suitable habitat.
Sedimentation
Sedimentation can affect fish species
by degrading physical habitat used for
foraging, sheltering, and spawning;
altering food webs and decreasing
stream productivity; forcing fish to
change their behaviors; and even
injuring or killing individual fish.
Chronic exposure to sediment has been
shown to have negative impacts to fish
gills, which in addition to causing gill
damage can possibly reduce growth
rates. Sedimentation causes reduced
visibility, impacting fishes’ abilities to
feed and interact.
A wide range of activities (including
agricultural activities, construction
activities, some forestry activities if
certified best management practices are
not used, and dredging), as well as
stormwater runoff, unpaved roads, and
utility crossings, can lead to
sedimentation within streams.
Historical land use practices have
substantially altered hydrological and
geological processes such that
sediments continue to be input into
streams for several decades after those
activities cease. Examples of these
activities occurring within the range of
the trispot darter include urban impacts
in the Springville, Alabama, and Dalton,
Georgia, areas; agricultural practices in
the Conasauga River basin; and
livestock access to streams in the Little
Canoe Creek watershed.

Reduced Connectivity
Connectivity relates to a species’
ability to disperse to and from habitat
patches. Excess groundwater
withdrawal, causing sections of streams
to become dry for parts of the year, can
reduce connectivity. Dams and
reservoirs reduce connectivity by
creating a physical barrier between fish
populations and by changing habitat
from flowing streams to standing water,
which is not suitable habitat for this
darter. Road crossings, some of which
have impassible culverts that reduce
connectivity, are also more prevalent in
highly populated urban areas. All of
these factors have occurred or are
occurring in the range of the trispot
darter.
Loss of Riparian Vegetation
This fish has adapted to occupy
habitats that are surrounded by
vegetation, which moderates
temperature by blocking solar radiation;
provides a source for terrestrial plant
VerDate Sep<11>2014
16:02 Dec 27, 2018
Jkt 247001
material that forms the base of the food
web and provides shelter and foraging
habitat for this fish; and helps to
maintain clear, clean water and
substrate through filtration. Removal of
riparian vegetation can destabilize
stream banks, increasing sedimentation
and turbidity; increase the contaminants
and nutrients that enter the water from
runoff; increase water temperatures and
light penetration, which also increases
algae production; and alter available
habitat by reducing woody plant debris
and leaf litter, which in turn decreases
overall stream productivity. All of these
events decrease habitat suitability for
the trispot darter. Removal of riparian
vegetation has occurred where urban
and agricultural practices are prevalent,
such as increased development in
Dalton, Chatsworth, and Ellijay, and
occurrences of row crops and pastures
in the Conasauga River basin generally.
Contaminants
Contaminants, including metals,
hydrocarbons, pesticides, and other
potentially harmful organic and
inorganic compounds, can be toxic to
fish and are common in urban streams,
including those within the range of the
trispot darter. Exposure to contaminants
may cause physiological stress to the
trispot darter as seen in other members
of the genus Etheostoma, and streams
affected by multiple sources of
contaminants may induce higher levels
of stress on the fish (Diamond et al.
2016; p. 133).
Contamination in the mainstem of the
Coosa River by polychlorinated
biphenyl (PCBs) has been attributed to
past industrial activity adjacent to the
river. In the Coosawattee River, PCBs
caused by nonpoint sources are also
identified as a source of impairment.
PCBs have toxic effects to the endocrine
system, nervous system, reproductive
system, blood, skin, and liver of
animals, and have likely impacted the
trispot darter in both basins.
Pesticides and herbicides are
frequently found in streams draining
agricultural land uses, with herbicides
being the most commonly detected.
Many agricultural streams still contain
dichlorodiphenyltrichloroethan (DDT)
and its degradation products. Pesticides
also are heavily used in urban and
suburban areas, and many of these find
their way into streams and groundwater.
Glyphosates and other inert ingredients
found in herbicides can be toxic to fish
and other aquatic organisms, causing
stress and reduced fitness; herbicide use
where the trispot darter occurs in the
Conasauaga River is prevalent and
increasing.

Frm 00102
Fmt 4700
Sfmt 4700
Agriculture
Agriculture is a predominant land use
within the range of the trispot darter.
Livestock grazing is prevalent in some
areas, and poultry farming is also
common.
Poultry Litter: Poultry litter is a
mixture of chicken manure, feathers,
spilled food, and bedding material that
frequently is used to fertilize
pastureland or row crops. Each poultry
house has an estimated ability to
produce up to 100 tons of litter a year.
Surface-spreading of litter results in
runoff from heavy rains carrying the
poultry litter into waterways, bringing
phosphorus and nitrogen from manure
into nearby streams. Additionally,
repeated or over application of poultry
litter can result in phosphorus buildup
in the soil, which then runs off into
streams. Excess phosphorus and
nitrogen in streams increases algae and
undesirable aquatic plants that rob
water of oxygen, causing fish kills.
Poultry litter also contains endocrine
disruptors, such as estrogen, which have
been identified as a significant stressor
within the Conasauga River basin.
Estrogens have been found in water and
sediment samples within the watershed
at concentrations high enough to be
disruptive to the endocrine system in
fish. Increased levels of estrogens affect
reproductive biology and result in
reduced breeding success. In a recent
study of endocrine disruptors on fishes
in the Conasauga River, approximately
7.5 percent of male fishes surveyed were
found to have female reproductive cells
in male reproductive organs.
Livestock Access to Streams: On many
farms, livestock is grazed on pastures
adjacent to streams and rivers, and is
allowed free access to the water.
Livestock accessing riparian buffers and,
subsequently, the stream proper leads to
habitat destruction and decreased water
quality. Livestock can destabilize stream
banks, which, as discussed above,
creates increased sediment loads within
small systems.
Urbanization
In addition to contributing to
individual stressors such as changes in
flow regime and contamination,
urbanization is anticipated to increase
the magnitude of nearly all other
stressors, and thus is expected to affect
the trispot darter across its range, which
is close to the growing Atlanta
metropolitan area, the expanding
Chattanooga and Birmingham areas, and
intervening areas with growing human
populations and increasing
development.

Weather Events
Weather events that affect stream
flows are considered to be most relevant
to the species. Broadly, these events
include extreme storms and droughts.
Increased flows can cause physical
washout of eggs and larval fishes, cause
stress on adults, and alter the
production in a stream. Within the
range of the trispot darter, extreme flows
associated with hurricanes have been
reported to have negative effects on
stream fish populations. On the other
hand, reduced baseflows due to
droughts can also cause population
declines, habitat loss, reduced water
quality (decreased dissolved oxygen and
temperature alteration) leading to death,
crowding of individuals leading to
stress, and decreased reproduction in
stream fish populations.
Climate models for the southeastern
United States project that average
annual temperatures will increase, cold
days will become less frequent, the
freeze-free season will lengthen,
temperatures exceeding 95 degrees
Fahrenheit will increase, heat waves
will become longer, and the number of
major hurricanes will increase. While
these climate models predict wide
variability in weather patterns into the
future, overall they suggest that the
region will be subjected to more
frequent large storms (hurricanes) as
well as low flows from droughts.
Other Stressors
In our analysis of the factors affecting
these species, we found no evidence of
population- or species-level impacts
from overutilization for commercial,
recreational, scientific, or educational
purposes (Factor B). Also, there was no
evidence of any impacts due to disease
or predation (Factor C). No existing
regulatory mechanisms adequately
address the threats to the trispot darter
such that it does not warrant listing
under the Act (Factor D).

Conservation Actions
The trispot darter is recognized by
Alabama, Georgia, and Tennessee as a
species of concern. This species is listed
as Priority 2/High Conservation Concern
by the State of Alabama, endangered by
the State of Georgia, and threatened by
the State of Tennessee. Priority
watersheds within the range of the
trispot darter have been designated as
Strategic Habitat Units by the Alabama
Rivers and Streams Network (ARSN).
ARSN is an organized partnership of
state and federal entities as well as
NGOs and corporations. Currently, the
trispot darter is found in the Big Canoe
Creek SHU and the Upper Coosa River

tributaries SHU. The Strategic Habitat
Unit project was developed for species
restoration and enhancement. To work
towards these goals, a thorough threats
analysis is conducted in each SHU by
partners to the ARSN, and the results of
the threats analyses guide State and
Federal agencies in prioritizing projects
that reduce and remove the identified
threats and ultimately improve habitat
and water quality for listed and at risk
species. The Atlantic Coast Conservancy
holds a tract of land within Ballplay
Creek that could offer some protection
in the watershed. The U.S. Department
of Agriculture’s Natural Resources
Conservation Service’s Working Lands
for Wildlife partnership within the
basin will help farmers develop and
implement strategies to improve water
quality.
Current Condition of Trispot Darter
To assess viability for the trispot
darter, we used the three conservation
biology principles of resiliency,
representation, and redundancy
(together, the 3Rs). Briefly, resiliency
supports the ability of the species to
withstand environmental and
demographic stochasticity (for example,
wet or dry, warm or cold years);
representation supports the ability of
the species to adapt over time to longterm changes in the environment (for
example, climate changes); and
redundancy supports the ability of the
species to withstand catastrophic events
(for example, droughts, hurricanes). In
general, the more redundant and
resilient a species is and the more
representation it has, the more likely it
is to sustain populations over time, even
under changing environmental
conditions. Using these principles, we
identified the species’ ecological
requirements for survival and
reproduction at the individual,
population, and species levels, and
described the factors influencing the
species’ viability.
The SSA process can be categorized
into three sequential stages. During the
first stage, we used the 3Rs to evaluate
individual life-history needs of all three
darters. In the next stage, we assessed
the historical and current condition of
each species’ demographics and habitat
characteristics, including an
explanation of how the species arrived
at their current conditions. In the final
stage of the SSA we made predictions
about the species’ responses to positive
and negative environmental and
anthropogenic influences. This process
used the best available information to
characterize viability as the ability of
each species to sustain populations in
the wild over time.

Frm 00103

To qualitatively assess resiliency, we
considered seven components that
broadly relate to either the physical
environment (‘‘Habitat Elements’’) or
characteristics about the population
specifically (‘‘Population Elements’’).
Habitat elements consisted of an
evaluation of physical habitat,
connectivity, water quality, and
hydrologic regime. Population elements
consisted of an estimation of
approximate abundance, the extent of
occurrence (total length of occupied
streams), and an assessment of
occurrence complexity. Representation
describes the ability of a species to
adapt to changing environmental
conditions over time. For trispot darters
to exhibit high representation, resilient
populations should occur in all
ecoregions to which they are native, and
maintain some level of connectivity
between populations. These occupied
physiographic provinces represent the
ecological setting in which the darters
have evolved. Redundancy is
characterized by having multiple
resilient and representative populations
distributed throughout its range.
Furthermore, these populations should
maintain natural levels of connectivity
between them. Connectivity allows for
immigration and emigration between
populations and increases the
likelihood of recolonization should a
population become extirpated. An
overall resiliency condition was
estimated by combining habitat and
population elements. Population
elements were weighted two times
higher than habitat elements because
they are considered direct indicators of
population condition. Conditions were
classified as ‘‘Low’’, ‘‘Moderate’’, or
‘‘High’’.
After analyzing current conditions for
the species, we described how current
viability of the three darters may change
over a period of 50 years. As with
current conditions, we evaluated
species viability in terms of resiliency at
the population scale, and representation
and redundancy at the species scale. In
the SSA report, we described three
plausible future scenarios and whether
there will be a change, from current
conditions, to resiliency, representation,
or redundancy under each scenario.
These scenarios capture the range of
likely viability outcomes that the trispot
darter is predicted to exhibit by the end
of 2070. The future scenarios differ in
two main elements of predicted change:
Urbanization and climate. To forecast
future urbanization, we considered
future scenarios that incorporate the
SLEUTH (Slope, Land use, Excluded
area, Urban area, Transportation,

Hillside area) model. This model
simulates patterns of urban expansion
that are consistent with spatial
observations of past urban growth and
transportation networks. Regarding
climate, the Intergovernmental Panel on
Climate Change utilized a suite of
alternative scenarios in the Fifth
Assessment Report to make near-term
and long-term climate projections. In
our assessments, we used these
projections to help understand how
climate may change in the future and
what effects may be observed that
impact the trispot darter.
Collection records used in the
analysis were compiled and provided to
the Service by State partners. These
records did not exhibit standardization:
The numbers of individuals collected
was inconsistently recorded and
sampling methods varied among
records. Therefore, we were unable to
analyze exact numbers collected for
each record. Instead, abundance was
estimated for each record categorically.
According to our analysis, all of the
current management units (MUs) have
resiliency ranked as ‘‘low’’ in the
analysis (see Table 1, below). Ballplay
Creek MU has a low resiliency because
of reduced genetic diversity, the
abundance is qualitatively low,
reservoirs and poor water quality
remove connectivity to other MUs, the
impairment of the Coosa River within
the watershed, and the extent of the
occupied habitat is small. The Little
Canoe Creek MU has a low resiliency to
stochastic events because water quality
and abundance are low (although the
occurrence complexity is high), Coosa
River reservoirs remove connectivity to
other MUs, and the extent of the
occupied habitat is small. Because of the
PCBs known in the area, the
Coosawattee River has low resiliency
due to hydrologic alteration from the
hydroelectric dam, PCBs in the river
contributing to low water quality, lower
abundance of fish per collection record,
a small and reduced distribution, and
overall simple occurrence spatial
arrangement. The Conasauga River MU
has low resiliency due to low water
quality in the middle and lower river,
low abundance of fish per collection
record, a reduced population, and
overall simple occurrence spatial
arrangement. For aquatic species that
inhabit rivers, complex spatial
occurrence relates to a species
occupying multiple tributaries and the
main-stem river as opposed to only
inhabiting the main-stem river. A more
complex and dendritic (tree-like) spatial
arrangement of occupied habitat will be
more resilient (Service 2017, p. 27).
Historically, the trispot darter was
found from the confluence of Holly
Creek to Chatsworth, Georgia and is
now only known from just upstream of
Chatsworth. Currently, the trispot darter
occupies approximately 20 percent of its
historically known range. While it is
clear the species has lost some of its
historical range, the best available data
do not indicate a declining trend in
abundance in the remaining areas from
historical to the present. This species is
rare and difficult to detect. Combined
with the inconsistent survey
methodology and lack of standard
collection records, this creates
uncertainty in any analysis of trends or
the ability to compare data across years.
A full analysis for each unit’s current
condition can be found in the SSA
Report and the proposed rule.

Future Conditions of Trispot Darter
For the purpose of this assessment,
we define viability as the ability of the
species to sustain populations in the
wild over time. To address uncertainty
associated with the degree and extent of
potential future stressors and their
impacts on species’ requisites, we
assessed the 3Rs using three plausible
future scenarios. These scenarios were
based, in part, on the results of
urbanization and climate models that
predict changes in habitat used by the
trispot darter. The models that were
used to forecast both urbanization and
climate change projected 50 years into
the future (the year 2070).
For example, in one scenario, current
environmental regulations and policy,
land use management techniques, and
conservations measures remain the
same over the next 50 years. We
anticipate the current trend in
greenhouse gas emissions to continue
and moderate impacts from extreme
weather events including intense

drought, floods, and storm events to
occur. Rapid urbanization will continue
at the current estimated rate for the
Piedmont region of the southeastern
United States, which will increase
demand for water resources and
introduce multiple additional stressors
into local streams and rivers. Despite an
overall growth in population and
increases in developed areas, some
regions will remain predominantly in
agriculture and experience associated
water quality declines. In pace with
current trends, we anticipate declines in
habitat and water quantity and quality
as a result of rapid urbanization, climate
change, agricultural practices, and an
overall lack of voluntary conservation
measures being implemented. Under
this scenario, two populations, Ballplay
Creek and Conasauga River, are
expected to become extirpated, while
the remaining two, Little Canoe Creek
and Coosawattee River, are projected to
persist but in low resiliency condition.

extirpation of trispot darters predicted
for Salacoa Creek (Coosawattee
population) in this scenario, the fish
would then be found only in the
Coosawattee River mainstem (no longer
in any tributaries), making it more
vulnerable to catastrophic events.
Redundancy decreases to two
populations (Little Canoe Creek and
Conasauga), which are completely
isolated from one another due to the
Weiss Dam. This means that genetic
material will not be exchanged,
reducing adaptive potential of the
species. In the SSA Report, we describe
conditions and results for all three
scenarios that represent the likely range
of plausible future outcomes for
development, possible climate changes,
and the species’ expected response to
threats. Results for our full future

Determination
We have carefully assessed the best
scientific and commercial information
available regarding the past, present,
and future threats to the trispot darter.
Our analysis of the trispot darter’s
current and future conditions, as well as
the conservation efforts discussed
above, show that the population and
habitat factors used to determine the
resiliency, representation, and
redundancy for trispot darter will
continue to decline such that it is likely
to become in danger of extinction
within the foreseeable future.
We considered whether the trispot
darter is presently in danger of
extinction throughout its range. The
current conditions as assessed in the
SSA Report show extant populations in
four river systems (MUs) across its
range, including 65 river miles (105
river kilometers) of occupied habitat in
the Conasauga River. The best available
data do not indicate a declining trend in
abundance, and it is likely that the low
abundance (and, therefore, low
resiliency) indicated in our analysis is
due to the species being naturally rare
and difficult to detect. The inconsistent
survey methodology and lack of
standard collection records also creates
uncertainty in any analysis of trends or
the ability to compare data across years.
While threats are currently acting on the
species and many of those threats are
expected to continue into the future, we
did not find that the species is currently
in danger of extinction throughout its
range.
Based on our analysis of plausible
future conditions of the trispot darter,
we concluded that the resiliency,
redundancy, and representation will be
impacted by threats and the species will
have reduced viability in the foreseeable
future. While our future scenarios were
developed using models that predicted
out 50 years, the short lifespan of the
species (2 to 3 years) and the lack of
data and research specific to trispot
darters regarding evidence of threats
directly impacting the species creates
uncertainty when predicting the
species’ response to threats into the
future. Forecasting beyond 8 to 10
generations (i.e., 16 to 24 years) would
be speculative, and we do not have
VerDate Sep<11>2014
16:02 Dec 27, 2018
Jkt 247001
robust population data to support a
foreseeable future that could accurately
predict how the trispot darter may
respond to threats beyond a 20-year
timeframe. Accordingly, we have
concluded that approximately 20 years
is the appropriate foreseeable future for
the trispot darter.
Our analysis concludes that 30 years
beyond our foreseeable future
timeframe, our range of plausible future
scenarios predicts the trispot darter may
continue to persist in as many as all four
of the populations; however, the entire
risk profile indicates that all four
populations could also possibly be
extirpated in 50 years. It is reasonable
to assume that at an intermediate
timeframe of 16 to 24 years, these
scenarios will not have been realized
completely; however, many populations
that persist are likely to have low
resiliency and continue to face threats.
Considering this species’ vulnerability
to a loss of connectivity between
breeding and nonbreeding habitats, and
the effect that situation has on
reproductive success, we expect
negative impacts to the resiliency,
redundancy, and representation of the
species in the foreseeable future. The
trispot darter’s unique reproductive
strategy of utilizing distinct areas of
rivers and streams for breeding and
nonbreeding habitats makes the loss of
connectivity especially detrimental to
viability. A lack of protected lands
within the current range of the trispot
darter creates more uncertainty
regarding land use, threats, and the
ability of these four populations to
withstand the expected loss of one or
two populations. This expected
reduction in both the number and
distribution of resilient populations is
likely to make the species vulnerable to
catastrophic disturbance. Therefore, on
the basis of the best available scientific
and commercial information, we find
that the species is likely to become in
danger of extinction within the
foreseeable future throughout its range.
Under the Act and our implementing
regulations, a species may warrant
listing if it is endangered or threatened
throughout all or a significant portion of
its range. Because we have determined
that the trispot darter is likely to become
an endangered species within the

foreseeable future throughout its range,
we find it unnecessary to proceed to an
evaluation of potentially significant
portions of the range. Where the best
available information allows the
Services to determine a status for the
species rangewide, that determination
should be given conclusive weight
because a rangewide determination of
status more accurately reflects the
species’ degree of imperilment and
better promotes the purposes of the
statute. In this way, assigning the
rangewide status to the species (rather
than potentially assigning a different
status based on a review of only a
portion of the range) best implements
the statutory distinction between
threatened and endangered species.
Maintaining this fundamental
distinction is important for ensuring
that conservation resources are allocated
toward species according to their actual
level of risk.
We also note that Congress placed the
‘‘all’’ language before the ‘‘significant
portion of its range’’ phrase in the
definitions of ‘‘endangered species’’ and
‘‘threatened species.’’ This suggests that
Congress intended that an analysis
based on consideration of the entire
range should receive primary focus, and
thus that the agencies should do a
‘‘significant portion of its range’’
analysis as an alternative to a rangewide
analysis only if necessary. Under this
reading, we should first consider
whether listing is appropriate based on
a rangewide analysis and proceed to
conduct a ‘‘significant portion of its
range’’ analysis if, and only if, a species
does not qualify for listing as either
endangered or threatened according to
the ‘‘all’’ language. We note that this
interpretation is also consistent with the
2014 Final Policy on Interpretation of
the Phrase ‘‘Significant Portion of its
Range’’ (SPR Policy) (79 FR 37578; July
1, 2014). That policy is the subject of
ongoing litigation, including litigation
against the Service in the United States
District Court for the Northern District
of California, which has vacated the
‘‘significant portion’’ part of the
Services’ SPR Policy (Desert Survivors v.
Department of the Interior, No. 16–cv–
01165–JCS (N.D. Cal. Aug. 24, 2018)).
However, our approach in this rule,
explained above, has been reached and

applied independently of the SPR

Available Conservation Measures
Conservation measures provided to
species listed as endangered or
threatened species under the Act
include recognition, recovery actions,
requirements for Federal protection, and
prohibitions against certain practices.
Recognition through listing results in
public awareness, and conservation by
Federal, State, Tribal, and local
agencies; private organizations; and
individuals. The Act encourages
cooperation with the States and requires
that recovery actions be carried out for
all listed species. The protection
required by Federal agencies and the
prohibitions against certain activities
are discussed, in part, below.
Recovery Actions
The primary purpose of the Act is the
conservation of endangered and
threatened species and the ecosystems
upon which they depend. The ultimate
goal of such conservation efforts is the
recovery of these listed species, so that
they no longer need the protective
measures of the Act. Subsection 4(f) of
the Act requires the Service to develop
and implement recovery plans for the
conservation of endangered and
threatened species. The recovery
planning process involves the
identification of actions that are
necessary to halt or reverse the species’
decline by addressing the threats to its
survival and recovery. The goal of this
process is to restore listed species to a
point where they are secure, selfsustaining, and functioning components
of their ecosystems.
Recovery planning includes the
development of a recovery outline
shortly after a species is listed and
preparation of a draft and final recovery
plan. The recovery outline guides the
immediate implementation of urgent
recovery actions and describes the
process to be used to develop a recovery
plan. Revisions of the plan may be done
to address continuing or new threats to
the species, as new substantive
information becomes available. The
recovery plan identifies site-specific
management actions that set a trigger for
review of the five factors that control
whether a species remains endangered
or may be reclassified from endangered
to threatened (‘‘downlisted’’) or
removed from listing (‘‘delisted’’), and
methods for monitoring recovery
progress. Recovery plans also establish
a framework for agencies to coordinate
their recovery efforts and provide
estimates of the cost of implementing
VerDate Sep<11>2014
16:02 Dec 27, 2018
Jkt 247001
recovery tasks. Recovery teams
(composed of species experts, Federal
and State agencies, nongovernmental
organizations, and other stakeholders)
are often established to develop
recovery plans. When completed, the
recovery outline, draft recovery plan,
and the final recovery plan will be
available on our website (https://
www.fws.gov/endangered) or from our
Alabama Ecological Services field office
(see FOR FURTHER INFORMATION CONTACT).
Implementation of recovery actions
generally requires the participation of a
broad range of partners, including other
Federal agencies, States, Tribes,
nongovernmental organizations,
businesses, and private landowners.
Examples of recovery actions include
habitat restoration (e.g., restoration of
native vegetation), research, captive
propagation and reintroduction, and
outreach and education. The recovery of
many listed species cannot be
accomplished solely on Federal lands
because their range may occur primarily
or solely on non-Federal lands. To
achieve recovery of these species
requires cooperative conservation efforts
on private, State, and Tribal lands.
Following publication of this final
listing rule, funding for recovery actions
will be available from a variety of
sources, including Federal budgets,
State programs, and cost share grants for
non-Federal landowners, the academic
community, and nongovernmental
organizations. In addition, pursuant to
section 6 of the Act, the States of
Alabama, Georgia, and Tennessee will
be eligible for Federal funds to
implement management actions that
promote the protection or recovery of
the trispot darter. Information on our
grant programs that are available to aid
species recovery can be found at: https://
www.fws.gov/grants.
Please let us know if you are
interested in participating in recovery
efforts for the trispot darter.
Additionally, we invite you to submit
any new information on this species
whenever it becomes available and any
information you may have for recovery
planning purposes (see FOR FURTHER
INFORMATION CONTACT).
Critical Habitat
Section 7(a) of the Act requires
Federal agencies to evaluate their
actions with respect to any species that
is listed as an endangered or threatened
species and with respect to its critical
habitat, if any is designated. Regulations
implementing this interagency
cooperation provision of the Act are
codified at 50 CFR part 402. Section
7(a)(2) of the Act requires Federal
agencies to ensure that activities they
PO 00000
Frm 00106
Fmt 4700
Sfmt 4700
authorize, fund, or carry out are not
likely to jeopardize the continued
existence of any endangered or
threatened species or destroy or
adversely modify its critical habitat. If a
Federal action may affect a listed
species or its critical habitat, the
responsible Federal agency must enter
into consultation with the Service.
Elsewhere in today’s Federal Register,
we propose to designate critical habitat
for the trispot darter under the Act.
Regulatory Provisions
Under section 4(d) of the Act, the
Service has discretion to issue
regulations that we find necessary and
advisable to provide for the
conservation of threatened species. The
Act and its implementing regulations set
forth a series of general prohibitions and
exceptions that apply to threatened
wildlife. The prohibitions of section
9(a)(1) of the Act, as applied to
threatened wildlife and codified at 50
CFR 17.31, make it illegal for any person
subject to the jurisdiction of the United
States to take (which includes harass,
harm, pursue, hunt, shoot, wound, kill,
trap, capture, or collect; or to attempt
any of these) threatened wildlife within
the United States or on the high seas. In
addition, it is unlawful to import;
export; deliver, receive, carry, transport,
or ship in interstate or foreign
commerce in the course of commercial
activity; or sell or offer for sale in
interstate or foreign commerce any
listed species. It is also illegal to
possess, sell, deliver, carry, transport, or
ship any such wildlife that has been
taken illegally. Certain exceptions apply
to employees of the Service, the
National Marine Fisheries Service, other
Federal land management agencies, and
State conservation agencies.
We may issue permits to carry out
otherwise prohibited activities
involving threatened wildlife under
certain circumstances. Regulations
governing permits are codified at 50
CFR 17.32. With regard to threatened
wildlife, a permit may be issued for the
following purposes: For scientific
purposes, for the enhancement of
propagation or survival, for economic
hardship, for zoological exhibition, for
educational purposes, for incidental
taking, or for special purposes
consistent with the purposes of the Act.
There are also certain statutory
exemptions from the prohibitions,
which are found in sections 9 and 10 of
the Act.
Section 4(d) of the Act specifies that,
for threatened species, the Secretary
shall issue such regulations as he deems
necessary and advisable to provide for
the conservation of the species. This
E:\FR\FM\28DER1.SGM
28DER1
67139
Federal Register / Vol. 83, No. 248 / Friday, December 28, 2018 / Rules and Regulations
discretion includes authority to prohibit
by regulation with respect to a
threatened species any act prohibited by
section 9(a)(1) of the Act. At 50 CFR
17.31(a), the Service, by delegation from
the Secretary, exercised this discretion
to extend the take and other
prohibitions set forth in section 9(a)(1)
of the Act to all threatened species. The
provisions at 50 CFR 17.31(c), however,
also provide that the prohibitions
included at 50 CFR 17.31(a) do not
apply if the Service promulgates a rule
under section 4(d) of the Act tailored to
provide for the conservation needs of a
specific threatened species. Elsewhere
in today’s Federal Register, we propose
to issue a rule under section 4(d) of the
Act (‘‘4(d) rule’’) that is tailored to the
specific threats to and conservation
needs of the trispot darter. Until a 4(d)
rule is made final for this species, all
prohibitions included at 50 CFR
17.31(a) apply to the trispot darter.
It is our policy, as published in the
Federal Register on July 1, 1994 (59 FR
34272), to identify to the maximum
extent practicable at the time a species
is listed, those activities that would or
would not constitute a violation of
section 9 of the Act. The intent of this
policy is to increase public awareness of
the effect of a final listing on proposed
and ongoing activities within the range
of a listed species. Activities that the
Service believes could potentially harm
the trispot darter and result in ‘‘take’’
include, but are not limited to:
(1) Unauthorized handling or
collecting of the species;
(2) Destruction or alteration of the
species’ habitat by discharge of fill
material, dredging, snagging,
impounding, channelization, or
modification of natural or artificial wet
weather conveyances or ephemeral,
intermittent, or perennial stream
channels or banks;
(3) Destruction of riparian habitat
directly adjacent to natural or artificial
wet weather conveyances or ephemeral,
intermittent, or perennial stream
channels that causes significant
increases in sedimentation and

destruction of natural stream banks or
channels;
(4) Discharge of pollutants into a
natural or artificial wet weather
conveyances or ephemeral, intermittent,
or perennial stream channels, or into
areas hydrologically connected to a
natural or artificial wet weather
conveyances or ephemeral, intermittent,
or perennial stream channel occupied
by the species;
(5) Diversion or alteration of surface
or ground water flow; and
(6) Pesticide/herbicide applications in
violation of label restrictions.
Questions regarding whether specific
activities constitute a violation of
section 9 of the Act should be directed
to the Alabama Ecological Services
Field Office (see ADDRESSES).

ACTION: Temporary rule; inseason
General category quota transfer.
AGENCY:
NMFS is transferring 19.5
metric tons (mt) of Atlantic bluefin tuna
(BFT) quota from the 28.9-mt General
category December 2019 subquota to the
January 2019 subquota period (from
January 1 through March 31, 2019, or
until the available subquota for this
period is reached, whichever comes
first). This action is based on
consideration of the regulatory
determination criteria regarding
inseason adjustments and applies to
Atlantic tunas General category
(commercial) permitted vessels and
Highly Migratory Species (HMS)
Charter/Headboat category permitted
vessels with a commercial sale
endorsement when fishing
commercially for BFT.
DATES: Effective January 1, 2019,
through March 31, 2019.

fishing categories, per the allocations
established in the 2006 Consolidated
Highly Migratory Species Fishery
Management Plan (2006 Consolidated
HMS FMP) (71 FR 58058, October 2,
2006), as amended by Amendment 7 to
the 2006 Consolidated HMS FMP
(Amendment 7) (79 FR 71510, December
2, 2014). NMFS is required under ATCA
and the Magnuson-Stevens Act to
provide U.S. fishing vessels with a
reasonable opportunity to harvest the
ICCAT-recommended quota.
The base quota for the General
category is 555.7 mt. See § 635.27(a).
Each of the General category time
periods (January, June through August,
September, October through November,
and December) is allocated a
‘‘subquota’’ or portion of the annual
General category quota. Although it is
called the ‘‘January’’ subquota, the
regulations allow the General category
fishery under this quota to continue
until the subquota is reached or March
31, whichever comes first. The baseline
subquotas for each time period are as
follows: 29.5 mt for January; 277.9 mt
for June through August; 147.3 mt for
September; 72.2 mt for October through
November; and 28.9 mt for December.
Any unused General category quota
rolls forward within the fishing year,
which coincides with the calendar year,
from one time period to the next, and
is available for use in subsequent time
periods.
Transfer of 19.5 mt From the December
2019 Subquota to the January 2019
Subquota
Under § 635.27(a)(9), NMFS has the
authority to transfer quota among
fishing categories or subcategories, after
considering regulatory determination
criteria provided under § 635.27(a)(8).
NMFS has considered all of the relevant
determination criteria and their
applicability to this inseason quota.
These considerations include, but are
not limited to, the following:
Regarding the usefulness of
information obtained from catches in
the particular category for biological
sampling and monitoring of the status of
the stock (§ 635.27(a)(8)(i)), biological
samples collected from BFT landed by
General category fishermen and
provided by tuna dealers provide NMFS
with valuable parts and data for ongoing
scientific studies of BFT age and
growth, migration, and reproductive
status. Additional opportunity to land
BFT, and potentially over a greater
portion of the January time period,
would support the collection of a broad
range of data for these studies and for
stock monitoring purposes.
PO 00000
Frm 00108
Fmt 4700

NMFS also considered the catches of
the General category quota to date
(including in December 2018 and during
the winter fishery in the last several
years), and the likelihood of closure of
that segment of the fishery if no
adjustment is made (§ 635.27(a)(8)(ii)).
Without a quota transfer from December
2019 to January 2019 for the General
category at this time, the quota available
for the January period would be 29.5 mt
(5.3 percent of the General category
quota), and participants would have to
stop BFT fishing activities once that
amount is met, while commercial-sized
BFT may remain available in the areas
where General category permitted
vessels operate. Transferring 19.5 mt of
the 28.9-mt quota available for
December 2019 (with 28.9 mt
representing 5.2 percent of the General
category quota) would result in 49 mt
(8.8 percent of the General category
quota) being available for the January
subquota period. This quota transfer
would provide additional opportunities
to harvest the U.S. BFT quota without
exceeding it, while preserving the
opportunity for General category
fishermen to participate in the winter
BFT fishery at both the beginning and
end of the calendar year.
Regarding the projected ability of the
vessels fishing under the particular
category quota (here, the General
category) to harvest the additional
amount of BFT before the end of the
fishing year (§ 635.27(a)(8)(iii)), NMFS
considered General category landings
over the last several years. General
category landings in the winter BFT
fishery tend to straddle the calendar
year as BFT may be available in late
November/December and into January
of the following year or later. Landings
are highly variable and depend on
access to commercial-sized BFT and
fishing conditions, among other factors.
Any unused General category quota
from the January subperiod that remains
as of March 31 will roll forward to the
next subperiod within the calendar year
(i.e., the June-August time period). In
2018, NMFS transferred 14.3 mt of
quota from the December 2018 subquota
to the January 2018 subquota period,
resulting in a subquota of 39 mt for the
January 2018 period and a subquota of
10 mt for the December 2018 period (82
FR 60680, December 22, 2017). NMFS
also transferred 10 mt from the Reserve
to the General category effective
February 28, resulting in an adjusted
subquota of 49 mt for the January 2018
period (83 FR 9232, March 5, 2018), and
closed the General category fishery for
the January subquota period effective
March 2, 2018. Under a one-fish General

SUPPLEMENTARY INFORMATION:
Previous Federal Actions
On October 4, 2017, we published a proposed rule in the Federal
Register (82 FR 46183) to list the trispot darter as a threatened
species under the Act (16 U.S.C. 1531 et seq.). Please refer to that
proposed rule for a detailed description of previous Federal actions
concerning this species.
Elsewhere in today's Federal Register, we propose to (1) designate
critical habitat for the trispot darter under the Act; and (2) issue a
rule under section 4(d) of the Act that provides measures necessary and
advisable for the conservation of the trispot darter.
Background
Please refer to the October 4, 2017, proposed rule (82 FR 46183)
and the Species Status Assessment (SSA) Report for a full summary of
species information. Both documents are available at https://www.regulations.gov under Docket No. FWS-R4-ES-2017-0063, and on the
Service's Southeast Region website at https://www.fws.gov/southeast/.
The trispot darter is a freshwater fish found in the Coosa River
System in the Ridge and Valley ecoregion of Alabama, Georgia, and
Tennessee. This fish has a historical range from the middle to upper
Coosa River Basin with collections in the mainstem Coosa, Oostanaula,
Conasauga, and Coosawattee Rivers, and their tributaries. Currently,
the trispot darter is known to occur in four populations in the Little
Canoe Creek and tributaries (Coosa River), Ballplay Creek tributaries
(Coosa River), Conasauga River and tributaries, and Coosawattee River
and one tributary.
The trispot darter is a migratory species that utilizes distinct
breeding and non-breeding habitats. From approximately April to
October, the species inhabits its non-breeding habitat, which consists
of small to medium river margins and lower reaches of tributaries with
slower velocities. It is associated with detritus, logs, and stands of
water willow, and the substrate consists of small cobbles, pebbles,
gravel, and often a fine layer of silt. During low flow periods, the
darters move away from the peripheral zones and toward the main
channel; edges of water willow beds, riffles, and pools; and mouths of
tributaries. In late fall, this migratory species shifts its habitat
preference and begins movement toward spawning areas; this is most
likely stimulated by precipitation, but temperature changes and
decreasing daylight hours may also provide cues to begin migration.
Migration into spawning areas begins approximately late November or
early December with fish moving from the main channels into tributaries
and eventually reaching adjacent seepage areas where they will
congregate and remain for the duration of spawning, approximately until
late April. Breeding sites are intermittent seepage areas and ditches
with little to no flow; shallow depths (12 inches (30 centimeters) or
less); moderate leaf litter covering mixed cobble, gravel, sand, and
clay; a deep layer of soft silt over clay; and emergent vegetation.
Trispot darters predominantly feed on mayfly nymphs and midge larvae
and pupae.
The trispot darter was first described in 1963 from a single
specimen collected in Cowans Creek in Cherokee County, Alabama. This
species was originally described as a member of the
[[Page 67132]]
subgenus Psychromaster and was later moved to the subgenus Ozarka in
1980 where it remains today. Currently, the trispot darter is
considered a valid taxon (Service 2017, p. 6).
Summary of Comments and Recommendations
In our October 4, 2017, proposed rule to list the trispot darter as
a threatened species (82 FR 46183), we requested that all interested
parties submit written comments on the proposal by December 4, 2017. We
also contacted appropriate Federal and State agencies, scientific
experts and organizations, and other interested parties, and invited
them to comment on the proposal. Newspaper notices inviting general
public comment were published in the St. Clair News-Aegis, St. Clair
Times, Chattanooga Times Free Press, Atlanta Journal Constitution, and
The Daily Home. We did not receive any requests for a public hearing.
All substantive information provided during the comment period has
either been incorporated directly into this final determination or is
addressed, by topic, below.
Peer Reviewer Comments
In accordance with our peer review policy published on July 1, 1994
(59 FR 34270), and our August 22, 2016, memorandum updating and
clarifying the role of peer review actions under the Act, we solicited
expert opinion from four knowledgeable individuals with scientific
expertise that included familiarity with trispot darter and its
habitat, biological needs, and threats. We received responses from two
of the peer reviewers.
We reviewed all comments we received from the peer reviewers for
substantive issues and new information regarding the information
contained in the SSA Report. The peer reviewers generally concurred
with our methods and conclusions, and provided additional information,
clarifications, and suggestions to improve the final SSA Report. Peer
reviewer comments are addressed in the following summary and were
incorporated into the final SSA Report as appropriate.
(1) Comment: One peer reviewer expressed doubt that hurricanes or
other large storms can negatively affect stream fish communities.
Our Response: Large storms have been found to disturb aquatic
habitats to the extent that stream fish assemblages have been observed
to be altered as a result (Service 2017, p. 25; Service 2011, p. 9).
Recovery of stream fish communities to assemblages seen before
disturbances from large storms depends on adjacent source populations
and the dispersal ability of specific species. In the case of rare
species with isolated populations such as the trispot darter, large
storms that are capable of causing a level of disturbance that alters
fish communities can pose a substantial threat. A more thorough
discussion of this threat can be found in the SSA Report (Service 2017,
p. 25).
(2) Comment: One peer reviewer suggested that not enough
information was available on the trispot darter to infer its historical
range.
Our Response: We are required to use the best available commercial
and scientific information available at the time we make our
determination. Available resources at the time of rulemaking have
described the range of the trispot darter as the upper Coosa River
system. Based on recorded occurrences of the trispot darter in the
mainstem of the Coosa River and tributaries to the Coosa River in
Alabama, Georgia, and Tennessee, we conclude that the historical range
described as the upper Coosa River system is reasonably supported.
Public Comments
(3) Comment: One commenter expressed concern about the presence of
the Conasauga Shale Field, a natural gas-bearing formation, within
portions of the trispot darter's range. The commenter provided current
research that demonstrated negative associations between hydraulic
fracturing (fracking) and fish recruitment, and recommended the Service
evaluate oil and gas exploration in the Conasauga Shale Field and its
influence on trispot darter.
Our Response: We contacted the Alabama State Oil and Gas Board to
assess the current and future status of natural gas exploration and
exploitation of the Conasauga Shale Field in Alabama. Based on our
correspondence, we find that fracking within the Conasauga Shale Field
is unlikely to be a threat to the trispot darter within the foreseeable
future. Currently, no new drilling permits have been approved, and all
existing wells have been plugged and abandoned. Wells were abandoned
due to low productivity and low gas prices. For these reasons, and
because of low permeability of the rock formation, the Alabama State
Oil and Gas Board expects that oil and gas extraction is unlikely to
occur there within the foreseeable future.
(4) Comment: One commenter provided additional information on the
effects of hypolimnetic releases from dams on riverine ecosystems and
fish species present in tailwaters. Hypolimnetic refers to the part of
a lake below the thermocline made up of water that is stagnant and of
essentially uniform temperature except during the period of overturn.
The commenter also noted that dams can create many kilometers of
unsuitable habitat because of changes in the temperature regime from
hypolimnetic flow releases. Decreases in streamflow temperature as a
result of hypolimnetic releases have been shown to adversely affect
darter species by increasing the probability of local extinction in
cold waters downstream of dams.
Our Response: We incorporated the information from the additional
studies clarifying the effects of hydropower projects on aquatic
species and have added them to the appropriate sections of the SSA
Report. We also recognize that currently the trispot darter is exposed
to releases from the Carters Reregulation Dam. However, past research
has found that operation of the reregulation dam does not affect the
system's ability to provide adequate dissolved oxygen for the trispot
darter (Freeman 2011, p. 10); this system also still meets State water
quality and temperature standards (USACE 2015, p. 4-13). Therefore,
temperature and dissolved oxygen alterations are not viewed as
stressors to the trispot darter in the Coosawattee River below the
Carters Reregulation Dam.
(5) Comment: One commenter noted that the overall condition of the
Little Canoe Creek Management Unit (MU) is ranked as moderate even
though six of the seven factors considered in the ranking scored as
``low'' in the October 4, 2017, proposed rule to list the trispot
darter as a threatened species (82 FR 46183).
Our Response: The overall condition for the Little Canoe Creek MU
presented in the proposed rule (see 82 FR 46187) and the SSA Report
(version 1.0) was in error. We have corrected the condition rank in
this rule and the updated SSA Report (version 1.2). However, this
correction does not change our assessment of future conditions in the
SSA Report, nor our conclusions presented in the October 4, 2017,
proposed rule.
Summary of Changes From the Proposed Rule
In preparing this final rule, we reviewed and fully considered
comments from the public on the proposed rule. We did not make any
substantive changes to this final rule after consideration of the
comments we received. We did update the SSA Report (to version 1.2)
based on comments and some additional information provided, as follows:
(1) We made many small, nonsubstantive clarifications and
[[Page 67133]]
corrections throughout the SSA Report, including ensuring consistency
of colors on maps, providing details about data sources used, updating
references, and making minor clarifications; and (2) we included in the
updated version of the SSA Report the additional information we
received regarding observations of the trispot darter, hypothesized
historical range of the trispot darter, and more detailed life-history
data for the species. However, the information we received during the
comment period for the proposed rule did not change our determination
that the trispot darter is a threatened species.
Summary of Biological Status and Threats
Section 4 of the Act (16 U.S.C. 1533), and its implementing
regulations in title 50 of the Code of Federal Regulations at 50 CFR
part 424, set forth the procedures for adding species to the Federal
Lists of Endangered and Threatened Wildlife and Plants. Under section
4(a)(1) of the Act, we may list a species based on (A) the present or
threatened destruction, modification, or curtailment of its habitat or
range; (B) overutilization for commercial, recreational, scientific, or
educational purposes; (C) disease or predation; (D) the inadequacy of
existing regulatory mechanisms; or (E) other natural or manmade factors
affecting its continued existence. These factors represent broad
categories of natural or human-caused actions or conditions that could
have an effect on a species' continued existence. In evaluating these
actions and conditions, we look for those that may have a negative
effect on individuals of the species, as well as other actions or
conditions that may ameliorate any negative effects or may have
positive effects.
We use the term ``threat'' to refer in general to actions or
conditions that are known to or are reasonably likely to negatively
affect individuals of a species. The term ``threat'' includes actions
or conditions that have a direct impact on individuals (direct
impacts), as well as those that affect individuals through alteration
of their habitat or required resources (stressors). The term ``threat''
may encompass--either together or separately--the source of the action
or condition or the action or condition itself. However, the mere
identification of any threat(s) does not necessarily mean that the
species meets the statutory definition of an ``endangered species'' or
a ``threatened species.'' In determining whether a species meets either
definition, we must evaluate all identified threats by considering the
expected response by the species, and the effects of the threats--in
light of those actions and conditions that will ameliorate the
threats--on an individual, population, and species level. We evaluate
each threat and its expected effects on the species, then analyze the
cumulative effect of all of the threats on the species as a whole. We
also consider the cumulative effect of the threats in light of those
actions and conditions that will have positive effects on the species--
such as any existing regulatory mechanisms or conservation efforts. The
Secretary determines whether the species meets the definition of an
``endangered species'' or a ``threatened species'' only after
conducting this cumulative analysis and describing the expected effect
on the species now and in the foreseeable future.
Our assessment evaluated the biological status of the species and
threats affecting its continued existence. It was based upon the best
available scientific and commercial data, including the SSA Report
(Service 2018, entire), and the expert opinion of the SSA team members.
Please refer to chapter 3 of the SSA Report (Service 2018, pp. 17-25)
for a more detailed discussion of the factors affecting the trispot
darter.
Risk Factors Influencing Viability of Trispot Darter
As discussed above, we considered the five factors set forth in
section 4(a)(1) of the Act in assessing whether the species meets the
definition of an endangered or a threatened species. A multitude of
natural and anthropogenic factors may impact the status of species
within aquatic systems. The largest threats to the future viability of
the trispot darter involve habitat degradation from factors influencing
four habitat elements: Water quality, water quantity, instream habitat,
and habitat connectivity (Factor A). All of these factors are
exacerbated by the effects of climate change (Factor E). A brief
summary of these primary stressors is presented below; for a full
description of the factors, refer to chapter 4 of the SSA Report.
Hydrologic Alteration
Activities that lead to hydrologic alteration include reservoir
construction and operation, excessive water withdrawals, and an
increase in impervious surfaces.
Hydrologic alteration in the system occupied by the trispot darter
has two components: Increases in storm flow frequency and intensity,
and a decrease in base flows, which together create a ``flashy''
hydrologic regime. In a natural forested system, most rainfall soaks
into the soil and is carried into nearby streams via subsurface flow.
Some evaporates or transpires, and a relatively small amount becomes
surface runoff. In the trispot darter's system, which is urbanized with
large amounts of impervious cover such as roads, parking lots, and
rooftops, this cycle is altered; most stormwater hits impervious
surfaces and becomes runoff, which then is channeled quickly to streams
via stormwater drain pipes or ditches. Relatively little infiltrates
into the soil. As a result, storm flows in the receiving stream are
higher and more frequent, although briefer in duration, and base flows
are lower, than in natural systems. The storm discharge of urban
streams can be twice that of rural streams draining a watershed of
similar size, and the frequency of channel-forming events can be 10
times that of pre-development conditions. These ``flashy'' stream flows
and frequent, smaller high-flow events negatively affect structural
habitat on which the trispot darter depends. Increases in flow
frequency or intensity can result in channel widening through bank
erosion or deepening to accommodate the additional discharge. This
results in increased downstream sedimentation and unstable beds, both
of which degrade channel complexity and feeding and refugia habitat for
fish species. Increased storm flows, in addition, can cause physical
washout of eggs and larval fishes, stress on adults, and negatively
alter the stream's food web, affecting many fish species. There is also
a decrease in channel complexity and a reduction in instream cover and
natural substrates like boulders, cobble, and gravel.
Reservoirs can substantially alter hydrology downstream, especially
when operated for hydroelectric power generation. Hydropeaking dams
produce high flows only when power generation is needed. Hydropeaking
dams, Carters Dam and Reregulation Dam, exist on the Coosawattee River.
Rapid flow increases and decreases from hydropeaking can reduce stream
insect abundance, potentially decreasing food availability for darters.
Furthermore, managed rivers can exhibit substantially altered and novel
food webs that affect native communities and their ability to withstand
perturbations. Non-hydropeaking reservoirs, farm ponds, amenity lakes,
and other impoundments may also substantially alter hydrologic regimes
by storing water during low flow periods, effectively dampening
moderate to high flows and in some cases augmenting flows. Fish are
adapted to the natural seasonal
[[Page 67134]]
variations of flow, and alterations to this regime affect their life-
history strategies.
Hydrologic alteration can also lead to other stressors, such as
sedimentation and a loss of connected suitable habitat.
Sedimentation
Sedimentation can affect fish species by degrading physical habitat
used for foraging, sheltering, and spawning; altering food webs and
decreasing stream productivity; forcing fish to change their behaviors;
and even injuring or killing individual fish. Chronic exposure to
sediment has been shown to have negative impacts to fish gills, which
in addition to causing gill damage can possibly reduce growth rates.
Sedimentation causes reduced visibility, impacting fishes' abilities to
feed and interact.
A wide range of activities (including agricultural activities,
construction activities, some forestry activities if certified best
management practices are not used, and dredging), as well as stormwater
runoff, unpaved roads, and utility crossings, can lead to sedimentation
within streams. Historical land use practices have substantially
altered hydrological and geological processes such that sediments
continue to be input into streams for several decades after those
activities cease. Examples of these activities occurring within the
range of the trispot darter include urban impacts in the Springville,
Alabama, and Dalton, Georgia, areas; agricultural practices in the
Conasauga River basin; and livestock access to streams in the Little
Canoe Creek watershed.
Reduced Connectivity
Connectivity relates to a species' ability to disperse to and from
habitat patches. Excess groundwater withdrawal, causing sections of
streams to become dry for parts of the year, can reduce connectivity.
Dams and reservoirs reduce connectivity by creating a physical barrier
between fish populations and by changing habitat from flowing streams
to standing water, which is not suitable habitat for this darter. Road
crossings, some of which have impassible culverts that reduce
connectivity, are also more prevalent in highly populated urban areas.
All of these factors have occurred or are occurring in the range of the
trispot darter.
Loss of Riparian Vegetation
This fish has adapted to occupy habitats that are surrounded by
vegetation, which moderates temperature by blocking solar radiation;
provides a source for terrestrial plant material that forms the base of
the food web and provides shelter and foraging habitat for this fish;
and helps to maintain clear, clean water and substrate through
filtration. Removal of riparian vegetation can destabilize stream
banks, increasing sedimentation and turbidity; increase the
contaminants and nutrients that enter the water from runoff; increase
water temperatures and light penetration, which also increases algae
production; and alter available habitat by reducing woody plant debris
and leaf litter, which in turn decreases overall stream productivity.
All of these events decrease habitat suitability for the trispot
darter. Removal of riparian vegetation has occurred where urban and
agricultural practices are prevalent, such as increased development in
Dalton, Chatsworth, and Ellijay, and occurrences of row crops and
pastures in the Conasauga River basin generally.
Contaminants
Contaminants, including metals, hydrocarbons, pesticides, and other
potentially harmful organic and inorganic compounds, can be toxic to
fish and are common in urban streams, including those within the range
of the trispot darter. Exposure to contaminants may cause physiological
stress to the trispot darter as seen in other members of the genus
Etheostoma, and streams affected by multiple sources of contaminants
may induce higher levels of stress on the fish (Diamond et al. 2016; p.
133).
Contamination in the mainstem of the Coosa River by polychlorinated
biphenyl (PCBs) has been attributed to past industrial activity
adjacent to the river. In the Coosawattee River, PCBs caused by
nonpoint sources are also identified as a source of impairment. PCBs
have toxic effects to the endocrine system, nervous system,
reproductive system, blood, skin, and liver of animals, and have likely
impacted the trispot darter in both basins.
Pesticides and herbicides are frequently found in streams draining
agricultural land uses, with herbicides being the most commonly
detected. Many agricultural streams still contain
dichlorodiphenyltrichloroethan (DDT) and its degradation products.
Pesticides also are heavily used in urban and suburban areas, and many
of these find their way into streams and groundwater. Glyphosates and
other inert ingredients found in herbicides can be toxic to fish and
other aquatic organisms, causing stress and reduced fitness; herbicide
use where the trispot darter occurs in the Conasauaga River is
prevalent and increasing.
Agriculture
Agriculture is a predominant land use within the range of the
trispot darter. Livestock grazing is prevalent in some areas, and
poultry farming is also common.
Poultry Litter: Poultry litter is a mixture of chicken manure,
feathers, spilled food, and bedding material that frequently is used to
fertilize pastureland or row crops. Each poultry house has an estimated
ability to produce up to 100 tons of litter a year. Surface-spreading
of litter results in runoff from heavy rains carrying the poultry
litter into waterways, bringing phosphorus and nitrogen from manure
into nearby streams. Additionally, repeated or over application of
poultry litter can result in phosphorus buildup in the soil, which then
runs off into streams. Excess phosphorus and nitrogen in streams
increases algae and undesirable aquatic plants that rob water of
oxygen, causing fish kills. Poultry litter also contains endocrine
disruptors, such as estrogen, which have been identified as a
significant stressor within the Conasauga River basin. Estrogens have
been found in water and sediment samples within the watershed at
concentrations high enough to be disruptive to the endocrine system in
fish. Increased levels of estrogens affect reproductive biology and
result in reduced breeding success. In a recent study of endocrine
disruptors on fishes in the Conasauga River, approximately 7.5 percent
of male fishes surveyed were found to have female reproductive cells in
male reproductive organs.
Livestock Access to Streams: On many farms, livestock is grazed on
pastures adjacent to streams and rivers, and is allowed free access to
the water. Livestock accessing riparian buffers and, subsequently, the
stream proper leads to habitat destruction and decreased water quality.
Livestock can destabilize stream banks, which, as discussed above,
creates increased sediment loads within small systems.
Urbanization
In addition to contributing to individual stressors such as changes
in flow regime and contamination, urbanization is anticipated to
increase the magnitude of nearly all other stressors, and thus is
expected to affect the trispot darter across its range, which is close
to the growing Atlanta metropolitan area, the expanding Chattanooga and
Birmingham areas, and intervening areas with growing human populations
and increasing development.
[[Page 67135]]
Weather Events
Weather events that affect stream flows are considered to be most
relevant to the species. Broadly, these events include extreme storms
and droughts. Increased flows can cause physical washout of eggs and
larval fishes, cause stress on adults, and alter the production in a
stream. Within the range of the trispot darter, extreme flows
associated with hurricanes have been reported to have negative effects
on stream fish populations. On the other hand, reduced baseflows due to
droughts can also cause population declines, habitat loss, reduced
water quality (decreased dissolved oxygen and temperature alteration)
leading to death, crowding of individuals leading to stress, and
decreased reproduction in stream fish populations.
Climate models for the southeastern United States project that
average annual temperatures will increase, cold days will become less
frequent, the freeze-free season will lengthen, temperatures exceeding
95 degrees Fahrenheit will increase, heat waves will become longer, and
the number of major hurricanes will increase. While these climate
models predict wide variability in weather patterns into the future,
overall they suggest that the region will be subjected to more frequent
large storms (hurricanes) as well as low flows from droughts.
Other Stressors
In our analysis of the factors affecting these species, we found no
evidence of population- or species-level impacts from overutilization
for commercial, recreational, scientific, or educational purposes
(Factor B). Also, there was no evidence of any impacts due to disease
or predation (Factor C). No existing regulatory mechanisms adequately
address the threats to the trispot darter such that it does not warrant
listing under the Act (Factor D).
Conservation Actions
The trispot darter is recognized by Alabama, Georgia, and Tennessee
as a species of concern. This species is listed as Priority 2/High
Conservation Concern by the State of Alabama, endangered by the State
of Georgia, and threatened by the State of Tennessee. Priority
watersheds within the range of the trispot darter have been designated
as Strategic Habitat Units by the Alabama Rivers and Streams Network
(ARSN). ARSN is an organized partnership of state and federal entities
as well as NGOs and corporations. Currently, the trispot darter is
found in the Big Canoe Creek SHU and the Upper Coosa River tributaries
SHU. The Strategic Habitat Unit project was developed for species
restoration and enhancement. To work towards these goals, a thorough
threats analysis is conducted in each SHU by partners to the ARSN, and
the results of the threats analyses guide State and Federal agencies in
prioritizing projects that reduce and remove the identified threats and
ultimately improve habitat and water quality for listed and at risk
species. The Atlantic Coast Conservancy holds a tract of land within
Ballplay Creek that could offer some protection in the watershed. The
U.S. Department of Agriculture's Natural Resources Conservation
Service's Working Lands for Wildlife partnership within the basin will
help farmers develop and implement strategies to improve water quality.
Current Condition of Trispot Darter
To assess viability for the trispot darter, we used the three
conservation biology principles of resiliency, representation, and
redundancy (together, the 3Rs). Briefly, resiliency supports the
ability of the species to withstand environmental and demographic
stochasticity (for example, wet or dry, warm or cold years);
representation supports the ability of the species to adapt over time
to long-term changes in the environment (for example, climate changes);
and redundancy supports the ability of the species to withstand
catastrophic events (for example, droughts, hurricanes). In general,
the more redundant and resilient a species is and the more
representation it has, the more likely it is to sustain populations
over time, even under changing environmental conditions. Using these
principles, we identified the species' ecological requirements for
survival and reproduction at the individual, population, and species
levels, and described the factors influencing the species' viability.
The SSA process can be categorized into three sequential stages.
During the first stage, we used the 3Rs to evaluate individual life-
history needs of all three darters. In the next stage, we assessed the
historical and current condition of each species' demographics and
habitat characteristics, including an explanation of how the species
arrived at their current conditions. In the final stage of the SSA we
made predictions about the species' responses to positive and negative
environmental and anthropogenic influences. This process used the best
available information to characterize viability as the ability of each
species to sustain populations in the wild over time.
To qualitatively assess resiliency, we considered seven components
that broadly relate to either the physical environment (``Habitat
Elements'') or characteristics about the population specifically
(``Population Elements''). Habitat elements consisted of an evaluation
of physical habitat, connectivity, water quality, and hydrologic
regime. Population elements consisted of an estimation of approximate
abundance, the extent of occurrence (total length of occupied streams),
and an assessment of occurrence complexity. Representation describes
the ability of a species to adapt to changing environmental conditions
over time. For trispot darters to exhibit high representation,
resilient populations should occur in all ecoregions to which they are
native, and maintain some level of connectivity between populations.
These occupied physiographic provinces represent the ecological setting
in which the darters have evolved. Redundancy is characterized by
having multiple resilient and representative populations distributed
throughout its range. Furthermore, these populations should maintain
natural levels of connectivity between them. Connectivity allows for
immigration and emigration between populations and increases the
likelihood of recolonization should a population become extirpated. An
overall resiliency condition was estimated by combining habitat and
population elements. Population elements were weighted two times higher
than habitat elements because they are considered direct indicators of
population condition. Conditions were classified as ``Low'',
``Moderate'', or ``High''.
After analyzing current conditions for the species, we described
how current viability of the three darters may change over a period of
50 years. As with current conditions, we evaluated species viability in
terms of resiliency at the population scale, and representation and
redundancy at the species scale. In the SSA report, we described three
plausible future scenarios and whether there will be a change, from
current conditions, to resiliency, representation, or redundancy under
each scenario. These scenarios capture the range of likely viability
outcomes that the trispot darter is predicted to exhibit by the end of
2070. The future scenarios differ in two main elements of predicted
change: Urbanization and climate. To forecast future urbanization, we
considered future scenarios that incorporate the SLEUTH (Slope, Land
use, Excluded area, Urban area, Transportation,
[[Page 67136]]
Hillside area) model. This model simulates patterns of urban expansion
that are consistent with spatial observations of past urban growth and
transportation networks. Regarding climate, the Intergovernmental Panel
on Climate Change utilized a suite of alternative scenarios in the
Fifth Assessment Report to make near-term and long-term climate
projections. In our assessments, we used these projections to help
understand how climate may change in the future and what effects may be
observed that impact the trispot darter.
Collection records used in the analysis were compiled and provided
to the Service by State partners. These records did not exhibit
standardization: The numbers of individuals collected was
inconsistently recorded and sampling methods varied among records.
Therefore, we were unable to analyze exact numbers collected for each
record. Instead, abundance was estimated for each record categorically.
According to our analysis, all of the current management units
(MUs) have resiliency ranked as ``low'' in the analysis (see Table 1,
below). Ballplay Creek MU has a low resiliency because of reduced
genetic diversity, the abundance is qualitatively low, reservoirs and
poor water quality remove connectivity to other MUs, the impairment of
the Coosa River within the watershed, and the extent of the occupied
habitat is small. The Little Canoe Creek MU has a low resiliency to
stochastic events because water quality and abundance are low (although
the occurrence complexity is high), Coosa River reservoirs remove
connectivity to other MUs, and the extent of the occupied habitat is
small. Because of the PCBs known in the area, the Coosawattee River has
low resiliency due to hydrologic alteration from the hydroelectric dam,
PCBs in the river contributing to low water quality, lower abundance of
fish per collection record, a small and reduced distribution, and
overall simple occurrence spatial arrangement. The Conasauga River MU
has low resiliency due to low water quality in the middle and lower
river, low abundance of fish per collection record, a reduced
population, and overall simple occurrence spatial arrangement. For
aquatic species that inhabit rivers, complex spatial occurrence relates
to a species occupying multiple tributaries and the main-stem river as
opposed to only inhabiting the main-stem river. A more complex and
dendritic (tree-like) spatial arrangement of occupied habitat will be
more resilient (Service 2017, p. 27).
Historically, the trispot darter was found from the confluence of
Holly Creek to Chatsworth, Georgia and is now only known from just
upstream of Chatsworth. Currently, the trispot darter occupies
approximately 20 percent of its historically known range. While it is
clear the species has lost some of its historical range, the best
available data do not indicate a declining trend in abundance in the
remaining areas from historical to the present. This species is rare
and difficult to detect. Combined with the inconsistent survey
methodology and lack of standard collection records, this creates
uncertainty in any analysis of trends or the ability to compare data
across years.
A full analysis for each unit's current condition can be found in
the SSA Report and the proposed rule.

Future Conditions of Trispot Darter
For the purpose of this assessment, we define viability as the
ability of the species to sustain populations in the wild over time. To
address uncertainty associated with the degree and extent of potential
future stressors and their impacts on species' requisites, we assessed
the 3Rs using three plausible future scenarios. These scenarios were
based, in part, on the results of urbanization and climate models that
predict changes in habitat used by the trispot darter. The models that
were used to forecast both urbanization and climate change projected 50
years into the future (the year 2070).
For example, in one scenario, current environmental regulations and
policy, land use management techniques, and conservations measures
remain the same over the next 50 years. We anticipate the current trend
in greenhouse gas emissions to continue and moderate impacts from
extreme weather events including intense drought, floods, and storm
events to occur. Rapid urbanization will continue at the current
estimated rate for the Piedmont region of the southeastern United
States, which will increase demand for water resources and introduce
multiple additional stressors into local streams and rivers. Despite an
overall growth in population and increases in developed areas, some
regions will remain predominantly in agriculture and experience
associated water quality declines. In pace with current trends, we
anticipate declines in habitat and water quantity and quality as a
result of rapid urbanization, climate change, agricultural practices,
and an overall lack of voluntary conservation measures being
implemented. Under this scenario, two populations, Ballplay Creek and
Conasauga River, are expected to become extirpated, while the remaining
two, Little Canoe Creek and Coosawattee River, are projected to persist
but in low resiliency condition. Because of the expected future
extirpation of trispot darters predicted for Salacoa Creek (Coosawattee
population) in this scenario, the fish would then be found only in the
Coosawattee River mainstem (no longer in any tributaries), making it
more vulnerable to catastrophic events. Redundancy decreases to two
populations (Little Canoe Creek and Conasauga), which are completely
isolated from one another due to the Weiss Dam. This means that genetic
material will not be exchanged, reducing adaptive potential of the
species. In the SSA Report, we describe conditions and results for all
three scenarios that represent the likely range of plausible future
outcomes for development, possible climate changes, and the species'
expected response to threats. Results for our full future condition
analysis for the future projections are provided in table 2, below and
are discussed more fully in the SSA Report and the proposed rule.

Determination
We have carefully assessed the best scientific and commercial
information available regarding the past, present, and future threats
to the trispot darter. Our analysis of the trispot darter's current and
future conditions, as well as the conservation efforts discussed above,
show that the population and habitat factors used to determine the
resiliency, representation, and redundancy for trispot darter will
continue to decline such that it is likely to become in danger of
extinction within the foreseeable future.
We considered whether the trispot darter is presently in danger of
extinction throughout its range. The current conditions as assessed in
the SSA Report show extant populations in four river systems (MUs)
across its range, including 65 river miles (105 river kilometers) of
occupied habitat in the Conasauga River. The best available data do not
indicate a declining trend in abundance, and it is likely that the low
abundance (and, therefore, low resiliency) indicated in our analysis is
due to the species being naturally rare and difficult to detect. The
inconsistent survey methodology and lack of standard collection records
also creates uncertainty in any analysis of trends or the ability to
compare data across years. While threats are currently acting on the
species and many of those threats are expected to continue into the
future, we did not find that the species is currently in danger of
extinction throughout its range.
Based on our analysis of plausible future conditions of the trispot
darter, we concluded that the resiliency, redundancy, and
representation will be impacted by threats and the species will have
reduced viability in the foreseeable future. While our future scenarios
were developed using models that predicted out 50 years, the short
lifespan of the species (2 to 3 years) and the lack of data and
research specific to trispot darters regarding evidence of threats
directly impacting the species creates uncertainty when predicting the
species' response to threats into the future. Forecasting beyond 8 to
10 generations (i.e., 16 to 24 years) would be speculative, and we do
not have robust population data to support a foreseeable future that
could accurately predict how the trispot darter may respond to threats
beyond a 20-year timeframe. Accordingly, we have concluded that
approximately 20 years is the appropriate foreseeable future for the
trispot darter.
Our analysis concludes that 30 years beyond our foreseeable future
timeframe, our range of plausible future scenarios predicts the trispot
darter may continue to persist in as many as all four of the
populations; however, the entire risk profile indicates that all four
populations could also possibly be extirpated in 50 years. It is
reasonable to assume that at an intermediate timeframe of 16 to 24
years, these scenarios will not have been realized completely; however,
many populations that persist are likely to have low resiliency and
continue to face threats. Considering this species' vulnerability to a
loss of connectivity between breeding and nonbreeding habitats, and the
effect that situation has on reproductive success, we expect negative
impacts to the resiliency, redundancy, and representation of the
species in the foreseeable future. The trispot darter's unique
reproductive strategy of utilizing distinct areas of rivers and streams
for breeding and nonbreeding habitats makes the loss of connectivity
especially detrimental to viability. A lack of protected lands within
the current range of the trispot darter creates more uncertainty
regarding land use, threats, and the ability of these four populations
to withstand the expected loss of one or two populations. This expected
reduction in both the number and distribution of resilient populations
is likely to make the species vulnerable to catastrophic disturbance.
Therefore, on the basis of the best available scientific and commercial
information, we find that the species is likely to become in danger of
extinction within the foreseeable future throughout its range.
Under the Act and our implementing regulations, a species may
warrant listing if it is endangered or threatened throughout all or a
significant portion of its range. Because we have determined that the
trispot darter is likely to become an endangered species within the
foreseeable future throughout its range, we find it unnecessary to
proceed to an evaluation of potentially significant portions of the
range. Where the best available information allows the Services to
determine a status for the species rangewide, that determination should
be given conclusive weight because a rangewide determination of status
more accurately reflects the species' degree of imperilment and better
promotes the purposes of the statute. In this way, assigning the
rangewide status to the species (rather than potentially assigning a
different status based on a review of only a portion of the range) best
implements the statutory distinction between threatened and endangered
species. Maintaining this fundamental distinction is important for
ensuring that conservation resources are allocated toward species
according to their actual level of risk.
We also note that Congress placed the ``all'' language before the
``significant portion of its range'' phrase in the definitions of
``endangered species'' and ``threatened species.'' This suggests that
Congress intended that an analysis based on consideration of the entire
range should receive primary focus, and thus that the agencies should
do a ``significant portion of its range'' analysis as an alternative to
a rangewide analysis only if necessary. Under this reading, we should
first consider whether listing is appropriate based on a rangewide
analysis and proceed to conduct a ``significant portion of its range''
analysis if, and only if, a species does not qualify for listing as
either endangered or threatened according to the ``all'' language. We
note that this interpretation is also consistent with the 2014 Final
Policy on Interpretation of the Phrase ``Significant Portion of its
Range'' (SPR Policy) (79 FR 37578; July 1, 2014). That policy is the
subject of ongoing litigation, including litigation against the Service
in the United States District Court for the Northern District of
California, which has vacated the ``significant portion'' part of the
Services' SPR Policy (Desert Survivors v. Department of the Interior,
No. 16-cv-01165-JCS (N.D. Cal. Aug. 24, 2018)). However, our approach
in this rule, explained above, has been reached and
[[Page 67138]]
applied independently of the SPR Policy, and is not inconsistent with
the court's holding in Desert Survivors.
Available Conservation Measures
Conservation measures provided to species listed as endangered or
threatened species under the Act include recognition, recovery actions,
requirements for Federal protection, and prohibitions against certain
practices. Recognition through listing results in public awareness, and
conservation by Federal, State, Tribal, and local agencies; private
organizations; and individuals. The Act encourages cooperation with the
States and requires that recovery actions be carried out for all listed
species. The protection required by Federal agencies and the
prohibitions against certain activities are discussed, in part, below.
Recovery Actions
The primary purpose of the Act is the conservation of endangered
and threatened species and the ecosystems upon which they depend. The
ultimate goal of such conservation efforts is the recovery of these
listed species, so that they no longer need the protective measures of
the Act. Subsection 4(f) of the Act requires the Service to develop and
implement recovery plans for the conservation of endangered and
threatened species. The recovery planning process involves the
identification of actions that are necessary to halt or reverse the
species' decline by addressing the threats to its survival and
recovery. The goal of this process is to restore listed species to a
point where they are secure, self-sustaining, and functioning
components of their ecosystems.
Recovery planning includes the development of a recovery outline
shortly after a species is listed and preparation of a draft and final
recovery plan. The recovery outline guides the immediate implementation
of urgent recovery actions and describes the process to be used to
develop a recovery plan. Revisions of the plan may be done to address
continuing or new threats to the species, as new substantive
information becomes available. The recovery plan identifies site-
specific management actions that set a trigger for review of the five
factors that control whether a species remains endangered or may be
reclassified from endangered to threatened (``downlisted'') or removed
from listing (``delisted''), and methods for monitoring recovery
progress. Recovery plans also establish a framework for agencies to
coordinate their recovery efforts and provide estimates of the cost of
implementing recovery tasks. Recovery teams (composed of species
experts, Federal and State agencies, nongovernmental organizations, and
other stakeholders) are often established to develop recovery plans.
When completed, the recovery outline, draft recovery plan, and the
final recovery plan will be available on our website (https://www.fws.gov/endangered) or from our Alabama Ecological Services field
office (see FOR FURTHER INFORMATION CONTACT).
Implementation of recovery actions generally requires the
participation of a broad range of partners, including other Federal
agencies, States, Tribes, nongovernmental organizations, businesses,
and private landowners. Examples of recovery actions include habitat
restoration (e.g., restoration of native vegetation), research, captive
propagation and reintroduction, and outreach and education. The
recovery of many listed species cannot be accomplished solely on
Federal lands because their range may occur primarily or solely on non-
Federal lands. To achieve recovery of these species requires
cooperative conservation efforts on private, State, and Tribal lands.
Following publication of this final listing rule, funding for
recovery actions will be available from a variety of sources, including
Federal budgets, State programs, and cost share grants for non-Federal
landowners, the academic community, and nongovernmental organizations.
In addition, pursuant to section 6 of the Act, the States of Alabama,
Georgia, and Tennessee will be eligible for Federal funds to implement
management actions that promote the protection or recovery of the
trispot darter. Information on our grant programs that are available to
aid species recovery can be found at: https://www.fws.gov/grants.
Please let us know if you are interested in participating in
recovery efforts for the trispot darter. Additionally, we invite you to
submit any new information on this species whenever it becomes
available and any information you may have for recovery planning
purposes (see FOR FURTHER INFORMATION CONTACT).
Critical Habitat
Section 7(a) of the Act requires Federal agencies to evaluate their
actions with respect to any species that is listed as an endangered or
threatened species and with respect to its critical habitat, if any is
designated. Regulations implementing this interagency cooperation
provision of the Act are codified at 50 CFR part 402. Section 7(a)(2)
of the Act requires Federal agencies to ensure that activities they
authorize, fund, or carry out are not likely to jeopardize the
continued existence of any endangered or threatened species or destroy
or adversely modify its critical habitat. If a Federal action may
affect a listed species or its critical habitat, the responsible
Federal agency must enter into consultation with the Service.
Elsewhere in today's Federal Register, we propose to designate
critical habitat for the trispot darter under the Act.
Regulatory Provisions
Under section 4(d) of the Act, the Service has discretion to issue
regulations that we find necessary and advisable to provide for the
conservation of threatened species. The Act and its implementing
regulations set forth a series of general prohibitions and exceptions
that apply to threatened wildlife. The prohibitions of section 9(a)(1)
of the Act, as applied to threatened wildlife and codified at 50 CFR
17.31, make it illegal for any person subject to the jurisdiction of
the United States to take (which includes harass, harm, pursue, hunt,
shoot, wound, kill, trap, capture, or collect; or to attempt any of
these) threatened wildlife within the United States or on the high
seas. In addition, it is unlawful to import; export; deliver, receive,
carry, transport, or ship in interstate or foreign commerce in the
course of commercial activity; or sell or offer for sale in interstate
or foreign commerce any listed species. It is also illegal to possess,
sell, deliver, carry, transport, or ship any such wildlife that has
been taken illegally. Certain exceptions apply to employees of the
Service, the National Marine Fisheries Service, other Federal land
management agencies, and State conservation agencies.
We may issue permits to carry out otherwise prohibited activities
involving threatened wildlife under certain circumstances. Regulations
governing permits are codified at 50 CFR 17.32. With regard to
threatened wildlife, a permit may be issued for the following purposes:
For scientific purposes, for the enhancement of propagation or
survival, for economic hardship, for zoological exhibition, for
educational purposes, for incidental taking, or for special purposes
consistent with the purposes of the Act. There are also certain
statutory exemptions from the prohibitions, which are found in sections
9 and 10 of the Act.
Section 4(d) of the Act specifies that, for threatened species, the
Secretary shall issue such regulations as he deems necessary and
advisable to provide for the conservation of the species. This
[[Page 67139]]
discretion includes authority to prohibit by regulation with respect to
a threatened species any act prohibited by section 9(a)(1) of the Act.
At 50 CFR 17.31(a), the Service, by delegation from the Secretary,
exercised this discretion to extend the take and other prohibitions set
forth in section 9(a)(1) of the Act to all threatened species. The
provisions at 50 CFR 17.31(c), however, also provide that the
prohibitions included at 50 CFR 17.31(a) do not apply if the Service
promulgates a rule under section 4(d) of the Act tailored to provide
for the conservation needs of a specific threatened species. Elsewhere
in today's Federal Register, we propose to issue a rule under section
4(d) of the Act (``4(d) rule'') that is tailored to the specific
threats to and conservation needs of the trispot darter. Until a 4(d)
rule is made final for this species, all prohibitions included at 50
CFR 17.31(a) apply to the trispot darter.
It is our policy, as published in the Federal Register on July 1,
1994 (59 FR 34272), to identify to the maximum extent practicable at
the time a species is listed, those activities that would or would not
constitute a violation of section 9 of the Act. The intent of this
policy is to increase public awareness of the effect of a final listing
on proposed and ongoing activities within the range of a listed
species. Activities that the Service believes could potentially harm
the trispot darter and result in ``take'' include, but are not limited
to:
(1) Unauthorized handling or collecting of the species;
(2) Destruction or alteration of the species' habitat by discharge
of fill material, dredging, snagging, impounding, channelization, or
modification of natural or artificial wet weather conveyances or
ephemeral, intermittent, or perennial stream channels or banks;
(3) Destruction of riparian habitat directly adjacent to natural or
artificial wet weather conveyances or ephemeral, intermittent, or
perennial stream channels that causes significant increases in
sedimentation and destruction of natural stream banks or channels;
(4) Discharge of pollutants into a natural or artificial wet
weather conveyances or ephemeral, intermittent, or perennial stream
channels, or into areas hydrologically connected to a natural or
artificial wet weather conveyances or ephemeral, intermittent, or
perennial stream channel occupied by the species;
(5) Diversion or alteration of surface or ground water flow; and

Required Determinations
National Environmental Policy Act (42 U.S.C. 4321 et seq.)
We have determined that environmental assessments and environmental
impact statements, as defined under the authority of the National
Environmental Policy Act, need not be prepared in connection with
listing a species as an endangered or threatened species under the
Endangered Species Act. We published a notice outlining our reasons for
this determination in the Federal Register on October 25, 1983 (48 FR
49244).
Government-to-Government Relationship With Tribes
In accordance with the President's memorandum of April 29, 1994
(Government-to-Government Relations with Native American Tribal
Governments; 59 FR 22951), Executive Order 13175 (Consultation and
Coordination with Indian Tribal Governments), and the Department of the
Interior's manual at 512 DM 2, we readily acknowledge our
responsibility to communicate meaningfully with recognized Federal
Tribes on a government-to-government basis. In accordance with
Secretarial Order 3206 of June 5, 1997 (American Indian Tribal Rights,
Federal-Tribal Trust Responsibilities, and the Endangered Species Act),
we readily acknowledge our responsibilities to work directly with
tribes in developing programs for healthy ecosystems, to acknowledge
that tribal lands are not subject to the same controls as Federal
public lands, to remain sensitive to Indian culture, and to make
information available to tribes. There are no tribal interests affected
by this rule.
