SUPPLEMENTARY INFORMATION:

Executive Summary

    Why we need to publish a rule. Under the Endangered Species Act of 
1973, as amended (Act), when we determine that a species is endangered 
or threatened we must designate critical habitat to the maximum extent 
prudent and determinable. Designations of critical habitat can only be 
completed by issuing a rule. Section 4(b)(2) of the Act states that the 
Secretary shall designate critical habitat on the basis of the best 
available scientific data after taking into consideration the economic 
impact, national security impact, and any other relevant impact of 
specifying any particular area as critical habitat. The critical 
habitat areas we are designating in this rule constitute our current 
best assessment of the areas that meet the definition of critical 
habitat for Leavenworthia exigua var. laciniata.
    This rule consists of: A final rule for designation of critical 
habitat for L. exigua var. laciniata. We are designating approximately 
2,053 acres (830 hectares) of critical habitat for L. exigua var. 
laciniata in Bullitt and Jefferson Counties, Kentucky. Elsewhere in 
today's Federal Register, we published a final rule listing L. exigua 
var. laciniata as a threatened species.
    We have prepared an economic analysis of the designation of 
critical habitat. We prepared an analysis of the economic impacts of 
the critical habitat designation and related factors. We announced the 
availability of the draft economic analysis in the Federal Register on 
January 7, 2014 (79 FR 796), allowing the public to provide comments on 
our analysis. We have incorporated the comments and have completed a 
final economic analysis concurrently with this final determination.
    Peer review and public comment. We sought comments from seven 
independent specialists to review our technical assumptions and 
analysis, and whether or not we used the best information, to ensure 
that this designation of critical habitat is based on scientifically 
sound data and analyses. We obtained opinions from three of those 
individuals. These peer reviewers generally concurred with our methods 
and conclusions. We also considered all comments and information we 
received from the public during the comment period.

Previous Federal Actions

    Please refer to the proposed listing rule for Leavenworthia exigua 
var. laciniata (78 FR 31498; May 24, 2013) for a detailed description 
of previous Federal actions concerning this species. On May 24, 2013, 
we proposed critical habitat for L. exigua var. laciniata (78 FR 
31479). On January 7, 2014 (79 FR 796), we announced the availability 
of the draft economic analysis (DEA) for the proposed critical habitat 
designation, and reopened the public comment period to allow comment on 
the DEA and further comment on the proposed rule.

Summary of Comments and Recommendations

    We requested written comments from the public on the proposed 
designation of critical habitat for L. exigua var. laciniata during two 
comment periods. The first comment period opened with the publication 
of the proposed rule (78 FR 31479) on May 24, 2013, and closed on July 
23, 2013. We also requested comments on the proposed critical habitat 
designation and associated draft economic analysis during a comment 
period that opened January 7, 2014, and closed on February 6, 2014 (79 
FR 796). We did not receive any requests for a public hearing. We also 
contacted appropriate Federal, State, and local agencies; scientific 
organizations; and other interested parties, and invited them to 
comment on the proposed rule and draft economic analysis during these 
comment periods.
    During the first comment period, we received two comment letters 
directly addressing the proposed critical habitat designation. During 
the second comment period, we received no comment letters addressing 
the proposed critical habitat designation or the draft economic 
analysis. All substantive information provided during the comment 
periods has either been incorporated directly into this final 
determination or is addressed below.

Peer Review

    In accordance with our peer review policy published on July 1, 1994 
(59 FR 34270), we solicited expert opinions from seven knowledgeable 
individuals with scientific expertise that included familiarity with 
the species, the geographic region in which the species occurs, and 
conservation biology principles. We received responses from three of 
the peer reviewers.
    We reviewed all comments we received from the peer reviewers for 
substantive issues and new information regarding critical habitat for 
L. exigua var. laciniata. Although the peer reviewers were supportive 
of the proposed critical habitat designation, they did not provide any 
additional

[[Page 25690]]

information, clarifications, or suggestions to improve this final 
critical habitat rule.

Comments From States

    The Commonwealth of Kentucky did not submit comments on the 
proposed rule. We note, however, that one of the peer reviewers was 
from the Kentucky State Nature Preserves Commission (KSNPC).

Public Comments

    During the public comment periods, we received two comment letters 
directly addressing the proposed critical habitat. These letters also 
addressed the proposed listing; comments pertaining to the listing are 
addressed in that final rule, published elsewhere in today's Federal 
Register. Both comment letters we received regarding the proposed 
critical habitat were positive and in support of the proposed 
designation.
    (1) Comment: One commenter noted that proposed subunits 4D and 4E 
are found along Bardstown Road in an area of high traffic and 
increasing commercial development.
    Our Response: We acknowledge that additional development in the 
area of subunits 4D and 4E has the potential to impact L. exigua var. 
laciniata and its habitat. Section 7 of the Act (16 U.S.C. 1531 et 
seq.) requires Federal agencies, in consultation with the Service, to 
ensure that any action authorized, funded, or carried out by a Federal 
agency (thereby constituting a Federal nexus) is not likely to result 
in the destruction or adverse modification of critical habitat. If 
there is no Federal nexus for a given action, then critical habitat 
designation, including on private land, does not restrict any actions 
that destroy or adversely modify critical habitat. The Service will 
provide technical assistance to avoid and minimize impacts to L. exigua 
var. laciniata's critical habitat if such assistance is requested.
    (2) Comment: The Service should take into consideration the 
economic benefits of conserving the State's natural heritage.
    Our Response: As required by Executive Order (E.O.) 12866 and 
section 4(b)(2) of the Act, the Service has completed an economic 
analysis on the effects of the critical habitat designation. The 
findings of this analysis were published in the Federal Register (79 FR 
796; January 7, 2014). While the Service recognizes that there will be 
benefits associated with designating critical habitat for this species, 
we are unable to assess the magnitude of these benefits due to existing 
data limitations.

Summary of Changes From Proposed Rule

    Information we received during the comment periods did not result 
in any substantial changes to this final rule from what we proposed.

Critical Habitat

Background

    Critical habitat is defined in section 3 of the Act as:
    (1) The specific areas within the geographical area occupied by the 
species, at the time it is listed in accordance with the Act, on which 
are found those physical or biological features
    (a) Essential to the conservation of the species, and
    (b) Which may require special management considerations or 
protection; and
    (2) Specific areas outside the geographical area occupied by the 
species at the time it is listed, upon a determination that such areas 
are essential for the conservation of the species.
    Conservation, as defined under section 3 of the Act, means to use 
and the use of all methods and procedures that are necessary to bring 
an endangered or threatened species to the point at which the measures 
provided pursuant to the Act are no longer necessary. Such methods and 
procedures include, but are not limited to, all activities associated 
with scientific resources management such as research, census, law 
enforcement, habitat acquisition and maintenance, propagation, live 
trapping, and transplantation, and, in the extraordinary case where 
population pressures within a given ecosystem cannot be otherwise 
relieved, may include regulated taking.
    Critical habitat receives protection under section 7 of the Act 
through the requirement that Federal agencies ensure, in consultation 
with the Service, that any action they authorize, fund, or carry out is 
not likely to result in the destruction or adverse modification of 
critical habitat. The designation of critical habitat does not affect 
land ownership or establish a refuge, wilderness, reserve, preserve, or 
other conservation area. Such designation does not allow the government 
or public to access private lands. Such designation does not require 
implementation of restoration, recovery, or enhancement measures by 
non-Federal landowners. Where a landowner requests Federal agency 
funding or authorization for an action that may affect a listed species 
or critical habitat, the consultation requirements of section 7(a)(2) 
of the Act would apply, but even in the event of a destruction or 
adverse modification finding, the obligation of the Federal action 
agency and the landowner is not to restore or recover the species, but 
to implement reasonable and prudent alternatives to avoid destruction 
or adverse modification of critical habitat.
    Under the first prong of the Act's definition of critical habitat, 
areas within the geographical area occupied by the species at the time 
it was listed are included in a critical habitat designation if they 
contain physical or biological features (1) which are essential to the 
conservation of the species and (2) which may require special 
management considerations or protection. For these areas, critical 
habitat designations identify, to the extent known using the best 
scientific and commercial data available, those physical or biological 
features that are essential to the conservation of the species (such as 
space, food, cover, and protected habitat). In identifying those 
physical or biological features within an area, we focus on the 
principal biological or physical constituent elements (primary 
constituent elements such as roost sites, nesting grounds, seasonal 
wetlands, water quality, tide, soil type) that are essential to the 
conservation of the species. Primary constituent elements are those 
specific elements of the physical or biological features that provide 
for a species' life-history processes and are essential to the 
conservation of the species.
    Under the second prong of the Act's definition of critical habitat, 
we can designate critical habitat in areas outside the geographical 
area occupied by the species at the time it is listed, upon a 
determination that such areas are essential for the conservation of the 
species. For example, an area currently occupied by the species but 
that was not occupied at the time of listing may be essential to the 
conservation of the species and may be included in the critical habitat 
designation. We designate critical habitat in areas outside the 
geographical area occupied by a species only when a designation limited 
to its range would be inadequate to ensure the conservation of the 
species.
    Section 4 of the Act requires that we designate critical habitat on 
the basis of the best scientific and commercial data available. 
Further, our Policy on Information Standards Under the Endangered 
Species Act (published in the Federal Register on July 1, 1994 (59 FR 
34271)), the Information Quality Act (section 515 of the Treasury and 
General

[[Page 25691]]

Government Appropriations Act for Fiscal Year 2001 (Pub. L. 106-554; 
H.R. 5658)), and our associated Information Quality Guidelines provide 
criteria, establish procedures, and provide guidance to ensure that our 
decisions are based on the best scientific data available. They require 
our biologists, to the extent consistent with the Act and with the use 
of the best scientific data available, to use primary and original 
sources of information as the basis for recommendations to designate 
critical habitat.
    When we are determining which areas should be designated as 
critical habitat, our primary source of information is generally the 
information developed during the listing process for the species. 
Additional information sources may include the recovery plan for the 
species, articles in peer-reviewed journals, conservation plans 
developed by States and counties, scientific status surveys and 
studies, biological assessments, other unpublished materials, or 
experts' opinions or personal knowledge.
    Habitat is dynamic, and species may move from one area to another 
over time. We recognize that critical habitat designated at a 
particular point in time may not include all of the habitat areas that 
we may later determine are necessary for the recovery of the species. 
For these reasons, a critical habitat designation does not signal that 
habitat outside the designated area is unimportant or may not be needed 
for recovery of the species. Areas that are important to the 
conservation of the species, both inside and outside the critical 
habitat designation, will continue to be subject to: (1) Conservation 
actions implemented under section 7(a)(1) of the Act, (2) regulatory 
protections afforded by the requirement in section 7(a)(2) of the Act 
for Federal agencies to insure their actions are not likely to 
jeopardize the continued existence of any endangered or threatened 
species, and (3) section 9 of the Act's prohibitions on taking any 
individual of the species, including taking caused by actions that 
affect habitat. Federally funded or permitted projects affecting listed 
species outside their designated critical habitat areas may still 
result in jeopardy findings in some cases. These protections and 
conservation tools will continue to contribute to recovery of this 
species. Similarly, critical habitat designations made on the basis of 
the best available information at the time of designation will not 
control the direction and substance of future recovery plans, habitat 
conservation plans (HCPs), or other species conservation planning 
efforts if new information available at the time of these planning 
efforts calls for a different outcome.

Physical or Biological Features

    In accordance with section 3(5)(A)(i) and 4(b)(1)(A) of the Act and 
regulations at 50 CFR 424.12, in determining which areas within the 
geographical area occupied by the species at the time of listing to 
designate as critical habitat, we consider the physical or biological 
features essential to the conservation of the species and which may 
require special management considerations or protection. These include, 
but are not limited to:
    (1) Space for individual and population growth and for normal 
behavior;
    (2) Food, water, air, light, minerals, or other nutritional or 
physiological requirements;
    (3) Cover or shelter;
    (4) Sites for breeding, reproduction, or rearing (or development) 
of offspring; and
    (5) Habitats that are protected from disturbance or are 
representative of the historical, geographical, and ecological 
distributions of a species.
    We derive the specific physical or biological features essential 
for L. exigua var. laciniata from studies of this species' habitat, 
ecology, and life history as described in the Critical Habitat section 
of the proposed rule to designate critical habitat published in the 
Federal Register on May 24, 2013 (78 FR 31479), and in the information 
presented below. Additional information can be found in the final 
listing rule published elsewhere in today's Federal Register. We have 
determined that the following physical and biological features are 
essential for L. exigua var. laciniata.

Space for Individual and Population Growth and for Normal Behavior

    Leavenworthia exigua var. laciniata is typically found in cedar or 
limestone glades (Baskin and Baskin 1981, p. 243), which are described 
by Baskin and Baskin (1999, p. 206) as ``open areas of rock pavement, 
gravel, flagstone, and/or shallow soil in which occur natural, long-
persisting (edaphic climax) plant communities dominated by angiosperms 
and/or cryptogams.'' L. exigua var. laciniata is also known from 
gladelike areas such as overgrazed pastures, eroded shallow soil areas 
with exposed bedrock, and areas where the soil has been scraped off the 
underlying bedrock (Evans and Hannan 1990, p. 8). These disturbed areas 
are gladelike in the shallowness or near-absence of their soils, 
saturation, and/or inundation during the wet periods of late fall, 
winter, and early spring and then frequently dry below the permanent 
wilting point during the summer (Baskin and Baskin 2003, p. 101). These 
conditions likely prevent species that would shade or compete with L. 
exigua var. laciniata from establishing in these areas.
    While the individual rock exposure or outcrop areas will vary in 
size and may be small and scattered throughout the glade(s) or 
gladelike area(s), they will ideally occur in groups to comprise a 
glade (or gladelike) complex. Habitat destruction, modification, and 
fragmentation within the narrow range of L. exigua var. laciniata make 
it difficult to determine the optimal size or density of glade habitats 
needed to support the long-term survival of the species. Pine Creek 
Barrens Preserve (owned by The Nature Conservancy) contains the only 
remaining A-ranked population of L. exigua var. laciniata, described as 
having thousands of plants scattered over 25 to 30 acres. Similarly, 
the B-ranked Rocky Run was described in 1990 as containing thousands of 
plants scattered over 2 miles. Many of the poor (D) ranked populations 
occur within areas as small as a few square meters (KSNPC 2012, pp. 1-
108). While the long-term viability of these populations is considered 
poor, monitoring efforts have shown that for the short term, some L. 
exigua var. laciniata populations are able to persist (i.e., grow and 
reproduce) on these small and fragmented sites.
    Based on the information above, we identify cedar glades and 
gladelike areas underlain by Silurian dolomite or dolomitic limestone 
as an essential physical or biological feature for the species.

Food, Water, Air, Light, Minerals, or Other Nutritional or 
Physiological Requirements

    The specific water needs of L. exigua var. laciniata are unknown; 
however, the sites it occupies are extremely wet from late winter to 
early spring and quickly become dry in late May and June. This 
hydrologic regime is critical for the plant's survival in that it 
provides sufficient moisture for the taxon's life cycle (germination in 
fall, plant growth from fall to early spring, and seed production in 
the spring). Additionally, the droughty conditions during the typical 
growing season prevent the establishment of plants that could shade or 
dominate L. exigua var. laciniata.
    L. exigua var. laciniata is shade intolerant. Open glade habitats 
appear to provide the most favorable conditions for this species (Evans 
and Hannan

[[Page 25692]]

1990, p. 14). Baskin and Baskin (1988, p. 834) noted that most endemics 
occurring on rock outcrops (such as L. exigua var. laciniata) are 
restricted to the open and well-lighted areas of the outcrops as 
opposed to similar but more shaded areas near the surrounding forest.
    L. exigua var. laciniata seems more dependent upon the lack of soil 
and the proximity of rock near or at the surface rather than a specific 
type of soil (Evans and Hannan 1990, p. 8). It occurs primarily in 
open, gravelly soils around rock outcrops in an area of the Caneyville-
Crider soil association (Whitaker and Waters 1986, p. 16). Baskin and 
Baskin (1981, p. 245) identified shallow soils (1 to 5 centimeters 
(cm)) (0.39 to 1.97 inches (in)) over limestone or dolomite to be 
characteristic habitat of L. exigua var. laciniata.
    Based on this information, we identify unshaded and shallow soils 
that are extremely wet from late winter to early spring and quickly 
become dry in late May and June to be an essential physical or 
biological feature for this species.

Sites for Breeding, Reproduction, or Rearing (or Development) of 
Offspring, Germination, or Seed Dispersal

    Like all annuals, L. exigua var. laciniata reproduces sexually 
through seed production. Successful reproduction of L. exigua var. 
laciniata requires sufficient moisture for germination, growth, 
flowering, and seed production. Pollination of L. exigua var. laciniata 
can be by insects or self-pollination (Rollins 1963, p. 47). Seeds may 
fall to the ground, be transported by animals, or be carried by 
precipitation sheet flow to new sites.
    The seeds of L. exigua var. laciniata germinate in the fall, with 
plants surviving through the winter as rosettes that flower in early 
spring. Seeds are typically dispersed from mid-May to late May (Evans 
and Hannan 1990, p. 11). After the seeds ripen, the silique (pod) soon 
splits open. Seeds may immediately fall out or remain on the plant for 
several days. The extent to which this plant can expand to new sites is 
unknown.
    Lloyd (1965, p. 92) noted that seeds from Leavenworthia lack 
adaptations that would allow for dispersal by wind or animals. Sheet 
flow likely provides local dispersion for seeds lying on the ground 
(Lloyd 1965, pp. 92-93; Evans and Hannan 1990, p. 11). In reviewing 
aerial photography and topographic mapping of known L. exigua var. 
laciniata occurrences, it appears that populations often follow 
suitable habitat as it extends along topographic contours or within 
drainage patterns. Areas of bare ground are essential in the dispersal 
and germination of seeds. The cyclical moisture availability on the 
thin soils of glades and other habitats acts to limit the number of 
plant species that can tolerate these extremes (Evans and Hannan 1990, 
pp. 9-10).
    L. exigua var. laciniata seeds have been shown to retain viability 
for at least 3 years under greenhouse conditions (Baskin and Baskin 
1981, p. 247). A strong seed bank is expected to be important for the 
continued existence of L. exigua var. laciniata, especially following a 
year when conditions are unfavorable for reproduction (e.g., damage 
(natural or manmade) to plants prior to seed set). Accordingly, L. 
exigua var. laciniata habitat must be protected from activities that 
would damage or destroy the seed bank.
    Based on the information above, we identify glade and gladelike 
habitats with intact hydrology and an undisturbed seed bank to be a 
physical or biological feature essential to the conservation of L. 
exigua var. laciniata. These areas are critical for seed dispersal and 
germination.

Habitats Protected From Disturbance or Representative of the 
Historical, Geographical, and Ecological Distribution of the Species

    Disturbance in the form of development (and associated 
infrastructure) is a major factor in the loss and degradation of 
habitat for L. exigua var. laciniata. Development can directly 
eliminate or fragment essential habitat and indirectly cause changes to 
the habitat (e.g., through erosion, shading, introduction of invasive 
plants--all of which may cause declines in distribution or in numbers 
of plants per occurrence). Protected habitats are, therefore, of 
crucial importance for the growth and dispersal of L. exigua var. 
laciniata. These areas are critical to protecting L. exigua var. 
laciniata populations and habitat from impacts such as sedimentation, 
erosion, and competition from nonnative or invasive plants.
    The natural areas supporting L. exigua var. laciniata are cedar or 
limestone glades, which Baskin and Baskin (2003, p. 101) describe as 
flat to gently sloping, open areas of shallow soils and/or calcareous 
rock (pavement, gravel, flagstone) that support an edaphic climax plant 
community dominated by non-woody species. These areas are often 
associated with eastern red-cedar thickets (Jones 2005, p. 33) and/or 
scrubby red-cedar-hardwood forests (Baskin and Baskin 1999, p. 102). 
These associated areas and other, adjacent, undeveloped ground provide 
important buffer protection from disturbance.
    Leavenworthia species have a patchy distribution within the exposed 
rock outcrops and shallow soil areas of cedar glade habitats and 
gladelike areas (Lloyd 1965, p. 87). L. exigua var. laciniata is an 
endemic species restricted to a very specific habitat type with a 
patchy distribution across the landscape separated by large areas of 
habitat unsuitable for L. exigua var. laciniata. Although these cedar 
glades also contain areas of deeper soil where other, associated 
vegetation grows, these areas of deeper soil are essential components 
of the glade and critical for maintaining habitat suitable for 
occupation by L. exigua var. laciniata.
    Based on a review of aerial imagery, habitat areas that appear to 
provide sufficient protection generally have the hillside (creek to 
topographic break) and adjacent contour surrounding the glade areas in 
vegetated (primarily wooded) habitat. Buffer areas of this magnitude 
protect L. exigua var. laciniata populations and habitat from adjacent 
development and habitat change. Although these areas are not directly 
occupied by L. exigua var. laciniata, they are essential to the growth 
and dispersal of the species within areas of suitable habitat.
    Therefore, based on the information above, we identify vegetated 
areas surrounding glades and gladelike habitats that protect the 
hydrology, soils, and seed bank to be a physical or biological feature 
for this species.

Primary Constituent Elements for L. exigua var. laciniata

    Under the Act and its implementing regulations, we are required to 
identify the physical or biological features essential to the 
conservation of L. exigua var. laciniata in areas occupied at the time 
of listing, focusing on the features' primary constituent elements. 
Primary constituent elements are those specific elements of the 
physical or biological features that provide for a species' life-
history processes and are essential to the conservation of the species.
    Based on our current knowledge of the physical or biological 
features and habitat characteristics required to sustain the species' 
life-history processes, we determine that the primary constituent 
elements specific to L. exigua var. laciniata are:
    (1) Cedar glades and gladelike areas within the range of L. exigua 
var. laciniata that include:
    (a) Areas of rock outcrop, gravel, flagstone of Silurian dolomite 
or dolomitic limestone, and/or shallow (1

[[Page 25693]]

to 5 cm (0.393 to 1.97 in)), calcareous soils;
    (b) Intact cyclic hydrologic regime involving saturation and/or 
inundation of the area in winter and early spring, then drying quickly 
in the summer;
    (c) Full or nearly full sunlight; and
    (d) An undisturbed seed bank.
    (2) Vegetated land around glades and gladelike areas that extends 
up and down slope and ends at natural (e.g., stream, topographic 
contours) or manmade breaks (e.g., roads).

Special Management Considerations or Protection

    When designating critical habitat, we assess whether the specific 
areas within the geographical area occupied by the species at the time 
of listing contain features that are essential to the conservation of 
the species and which may require special management considerations or 
protection.
    Threats to those features that define primary constituent elements 
for L. exigua var. laciniata include (but are not limited to): (1) 
Residential and commercial development on private land; (2) 
construction and maintenance of roads and utility lines; (3) 
incompatible agricultural or grazing practices; (4) off-road vehicle 
(ORV) use or horseback riding; (5) encroachment by nonnative plants or 
forage species; and (6) forest encroachment due to fire suppression. 
These threats are in addition to random effects of droughts, floods, or 
other natural phenomena.
    Special management considerations or protection are required within 
critical habitat areas to address these threats. Management activities 
that could address these threats include (but are not limited to): (1) 
Avoiding cedar glades (or suitable gladelike habitats) when planning 
the location of buildings, lawns, roads (including horse or ORV 
trails), or utilities; (2) avoiding aboveground construction and/or 
excavations in locations that would interfere with natural water 
movement to suitable habitat sites; (3) protecting and restoring as 
many glade complexes as possible; (4) research supporting the 
development of management recommendations for grazing and other 
agricultural practices; (5) technical or financial assistance to 
landowners that may help in the design and implementation of management 
actions that protect the plant and its habitat; (6) avoiding lawn grass 
or tree plantings near glades; and (7) habitat management, such as 
brush removal, prescribed fire, and/or eradication of lawn grasses to 
maintain an intact native glade vegetation community.

Criteria Used To Identify Critical Habitat

    As required by section 4(b)(2) of the Act, we use the best 
scientific data available to designate critical habitat. In accordance 
with the Act and our implementing regulations at 50 CFR 424.12(b) we 
review available information pertaining to the habitat requirements of 
the species and identify areas occupied at the time of listing that 
contain the features essential to the conservation of the species. If, 
after identifying currently occupied areas, we determine that those 
areas are inadequate to ensure conservation of the species we then 
consider, in accordance with the Act and our implementing regulations 
at 50 CFR 424.12(e), whether designating additional areas outside those 
currently occupied is essential for the conservation of the species. 
Here, we are not designating any areas outside the geographical area 
occupied by the species because we have determined that occupied areas 
are sufficient for the conservation of the species, and we have no 
evidence that this taxon ever existed beyond its current range.
    Sites were considered occupied if the Kentucky State Nature 
Preserves Commission (KSNPC) Element Occurrence Report (KSNPC 2012, pp. 
1-108) considered an element occurrence to be an extant population at 
the time of the proposed listing rule (May 24, 2013).
    We also reviewed available information that pertains to habitat 
requirements of Leavenworthia exigua var. laciniata. The sources of 
information include, but are not limited to:
    1. Data used to prepare the proposed listing package;
    2. Peer-reviewed articles, various agency reports, and the KSNPC 
Natural Heritage Program database;
    3. Information from species experts; and
    4. Regional Geographic Information System (GIS) data (such as 
species occurrence data, topography, aerial imagery, and land ownership 
maps) for area calculations and mapping.
    Areas for critical habitat designation were selected based on the 
quality of the element occurrence(s), condition of the habitat, and 
distribution within the species' range. Typically, selected areas 
contain good quality or better occurrences (A, B, or C-ranked) and 
natural habitat, as identified by KSNPC in the Natural Heritage Report 
(2012, pp. 1-108). However, some lower quality occurrences, with 
restoration potential, are included to ensure that critical habitat is 
being designated across the species' range and to avoid a potential 
reduction of the distribution of L. exigua var. laciniata. The glade 
habitat upon which the species depends is often easily viewed using 
aerial photography. Additionally, aerial photography provides an 
overview of the land use surrounding the glades. Topographic maps 
provide contours and drainage patterns that were used to help identify 
potential areas for growth and expansion of the species. A combination 
of these tools, in a GIS interface, allowed for the determination of 
the critical habitat boundaries.
    When determining critical habitat boundaries, we made every effort 
to avoid including developed areas such as lands covered by buildings, 
pavement, and other structures because such lands lack physical or 
biological features for L. exigua var. laciniata. The scale of the maps 
we prepared under the parameters for publication within the Code of 
Federal Regulations may not reflect the exclusion of such developed 
lands. Any such lands inadvertently left inside critical habitat 
boundaries shown on the maps of this final rule have been excluded by 
text and are not designated as critical habitat. Therefore, a Federal 
action involving these lands will not trigger section 7 consultation 
with respect to critical habitat and the requirement of no adverse 
modification unless the specific action would affect the physical or 
biological features in the adjacent critical habitat.
    The critical habitat designation is defined by the map or maps, as 
modified by any accompanying regulatory text, presented at the end of 
this document in the Regulation Promulgation section. We include more 
detailed information on the boundaries of the critical habitat 
designation in the preamble of this document. We will make the 
coordinates or plot points or both on which each map is based available 
to the public on https://www.regulations.gov at Docket No. FWS-R4-ES-
2013-0015, and at the field office responsible for the designation (see 
FOR FURTHER INFORMATION CONTACT).

Final Critical Habitat Designation

    We are designating six units, consisting of 18 subunits, as 
critical habitat for L. exigua var. laciniata. The critical habitat 
areas described below constitute our best assessment at this time of 
areas that meet the definition of critical habitat. Those six units 
are: (1) Unit 1: McNeely Lake, (2) Unit 2: Old Mans Run, (3) Unit 3: 
Mount Washington, (4) Unit 4: Cedar Creek, (5) Unit 5: Cox Creek, and 
(6) Unit 6: Rocky Run. All units and subunits are

[[Page 25694]]

currently occupied by the species and contain all physical and 
biological features and primary constituent elements that are essential 
to the conservation of the species.

Note: Area sizes may not sum due to rounding.

Unit 1: McNeely Lake, Jefferson County, Kentucky

    Unit 1 consists of 18 acres (ac) (7 hectares (ha)) within McNeely 
Lake Park in Jefferson County, Kentucky. This critical habitat unit is 
under county government ownership. This critical habitat unit occurs at 
the northwestern edge of the species' range, where there is little 
remaining habitat and few occurrences, and therefore this unit is 
important to the distribution of the species. Habitat degradation 
(e.g., erosion, invasive species) is impacting the species' ability to 
persist within this unit; however, the landowner has received funding 
and is working with the Service and KSNPC to develop a management plan 
for the site and to implement habitat improvement practices. These 
planned activities are expected to improve population numbers and 
viability at this important site. This unit helps to maintain the 
geographical range of the species and provides opportunity for 
population growth. Within Unit 1, the features essential to the 
conservation of the species may require special management 
considerations or protection to address potential adverse effects 
associated with encroachment by nonnative plants or forage species, and 
forest encroachment due to fire suppression.

Unit 2, Subunits A, B, and C: Old Mans Run, Jefferson and Bullitt 
Counties, Kentucky

    Unit 2 consists of three subunits totaling 1,014 ac (410 ha) in 
Bullitt and Jefferson Counties, Kentucky. It is located just south of 
the Jefferson/Bullitt County line and extends north of Old Mans Run. 
This critical habitat unit includes four element occurrences. Subunit 
2B represents the best remaining populations and habitat for L. exigua 
var. laciniata in Jefferson County. Subunits 2A and 2C are important 
areas at the northern extent of the species' range. These three 
subunits represent the northeastern extent of the population's range 
and increase population redundancy within the species' range. The 
features essential to the conservation of the species in Unit 2 may 
require special management considerations or protection to address 
potential adverse effects associated with development on private land, 
incompatible agricultural or grazing practices, ORV or horseback 
riding, competition from lawn grasses, and forest encroachment.
    Subunit 2A is 102 ac (41 ha) in size and is located west of US 150 
and northwest of Floyds Fork. It is in private ownership. While all 
PCEs are present within this subunit, it contains few native plant 
associates for L. exigua var. laciniata, and the increased competition 
from lawn grasses may decrease the ability of L. exigua var. laciniata 
to persist. This subunit is important for maintaining the northern 
distribution of L. exigua var. laciniata.
    Subunit 2B is 870 ac (352 ha) in size and is located east of US 150 
and extends north and south of Old Mans Run. It is in private 
ownership. This is the largest of the subunits and contains the two 
highest ranked (1-B and 1-C) occurrences in Jefferson County. It 
represents the best remaining habitat in this portion of the range and 
may contain more than half of the total L. exigua var. laciniata 
population based on a 2011 survey by KSNPC, which estimated more than 
20,000 individuals at 4 sites within this subunit. In this subunit, 
competition from lawn grasses impacts L. exigua var. laciniata and may 
decrease the plant's ability to persist.
    Subunit 2C is 42 ac (17 ha) in size and is located west of US 150 
and east of Floyds Fork, extending into both Bullitt and Jefferson 
Counties. It is in private ownership. This subunit is primarily 
pasture, and habitat for L. exigua var. laciniata is impacted by 
competition from lawn grasses. Habitat management within this subunit 
to improve habitat for L. exigua var. laciniata is important for 
maintaining the northern distribution of the species.

Unit 3, Subunits A, B and C: Mount Washington, Bullitt County, Kentucky

    Unit 3 consists of 42 ac (17 ha) and includes three subunits in 
Bullitt

[[Page 25695]]

County, Kentucky, primarily within or adjacent to the city limits of 
Mount Washington. This critical habitat unit includes three element 
occurrences and provides an important link between the northern and 
southern portions of the species' range. Within Unit 3, the features 
essential to the conservation of the species may require special 
management considerations or protection to address potential adverse 
effects associated with development on private land, incompatible 
agricultural or grazing practices, ORV or horseback riding, competition 
from lawn grasses, and forest encroachment due to fire suppression.
    Subunit 3A is 25 ac (10 ha) in size and is located northeast of 
Mount Washington. It is in private ownership. Habitat for L. exigua 
var. laciniata within this subunit is degraded and would improve with 
management. It represents important habitat on the eastern extent of 
the species' range. In this subunit, habitat conversion and ORV use 
impact L. exigua var. laciniata habitat and may decrease the species' 
ability to persist at this site.
    Subunit 3B is 7 ac (3 ha) in size and is located east of Hubbard 
Lane and south of Keeneland Drive. It is in private ownership. The 
glade habitat has been degraded by adjacent land use and would benefit 
from improved management. The subunit represents an important link 
between other subunits.
    Subunit 3C is 10 ac (4 ha) in size and is located east of US 150 
and south of Highway 44E. It is in private ownership. The subunit 
represents an important and high quality cedar glade in an area of 
ongoing, intensive development. Land use surrounding the glade remnant 
appears stable and the glade contains several native plant species 
associated with L. exigua var. laciniata.

Unit 4, Subunits A, B, C, D, E, F, G, and H: Cedar Creek, Bullitt 
County, Kentucky

    Unit 4 consists of 547 ac (221 ha) and includes eight subunits, all 
in Bullitt County, Kentucky. This unit is located south of the Salt 
River and northeast of Cedar Grove and seems to represent the core of 
the remaining high-quality habitat for L. exigua var. laciniata. It 
includes eight element occurrences. In addition to being a stronghold 
for the species, these subunits are generally within close proximity 
(less than 0.5 miles (0.8 km)) to each other and represent the best 
opportunity for genetic exchange between occurrences.
    Within Unit 4, the features essential to the conservation of the 
species may require special management considerations or protection to 
address potential adverse effects associated with development on 
private land, incompatible agricultural or grazing practices, ORV or 
horseback riding, competition from lawn grasses, and forest 
encroachment due to fire suppression.
    Subunit 4A is 91 ac (37 ha) in size and is located south of Cedar 
Creek and west of Pine Creek Trail. This subunit is owned by The Nature 
Conservancy and encompasses most of the Pine Creek Barrens Preserve. 
This excellent-quality glade represents the only remaining ``A'' rank 
occurrence for L. exigua var. laciniata.
    Subunit 4B is 69 ac (28 ha) in size and is located along an unnamed 
tributary to Cedar Creek, and south of KY 1442. This good-quality glade 
includes the Apple Valley Glade State Nature Preserve, owned by KSNPC 
(approximately 30 percent of subunit), as well as private land, 
including some under permanent conservation easement (approximately 41 
percent of subunit) to protect L. exigua var. laciniata. Approximately 
29 percent of this subunit is under private ownership without any 
protections for L. exigua var. laciniata.
    Subunit 4C is 83 ac (34 ha) in size and located north of Cedar 
Creek and south of Apple Valley State Nature Preserve. It is in private 
ownership. This subunit contains high-quality glades with a community 
of native plants present.
    Subunit 4D is 46 ac (19 ha) in size and is located north of Cedar 
Creek and south of Victory Church. It is in private ownership. This 
subunit has been degraded and would benefit from improved management. 
Native plants associated with L. exigua var. laciniata occur within 
this subunit, but competition from lawn grasses, as well as forest 
encroachment due to fire suppression, impacts L. exigua var. laciniata 
and may decrease its ability to persist.
    Subunit 4E is 102 ac (41 ha) in size and is located southeast of 
subunit 4D and across Cedar Creek. It is in private ownership. It 
contains a large number of L. exigua var. laciniata (several thousand), 
but the habitat has been degraded by adjacent land use and would 
benefit from improved management. Competition from lawn grasses, as 
well as forest encroachment due to fire suppression, affects L. exigua 
var. laciniata and may decrease the plant's ability to persist.
    Subunit 4F is 120 ac (49 ha) in size and is south of the confluence 
of Cedar Creek and Greens Branch. It is in private ownership. This is a 
degraded glade that still contains native plants associated with L. 
exigua var. laciniata. The subunit is disturbed by existing and 
surrounding land uses, as well as utility line maintenance and ORV use, 
which may decrease the species' ability to persist.
    Subunit 4G is 20 ac (8 ha) in size and is located along either site 
of KY 480 near White Run Road. It is in private ownership. This site 
contains a large number of plants; however, improved habitat conditions 
are needed for long-term viability of the L. exigua var. laciniata 
occurrence. Impacts to L. exigua var. laciniata, which may decrease its 
ability to persist at this site, include incompatible agricultural or 
grazing practices, ORV use, competition from lawn grasses, and forest 
encroachment due to fire suppression.
    Subunit 4H is 16 ac (6 ha) in size and is located 0.95 miles 
southeast of the KY 480/KY 1604 intersection. It is in private 
ownership. Within this subunit, several patches of good habitat for L. 
exigua var. laciniata remain as well as a good diversity of native 
plant associates. However, competition from lawn grasses, as well as 
forest encroachment due to fire suppression, affects L. exigua var. 
laciniata and may decrease its ability to persist.

Unit 5, Subunits A and B: Cox Creek, Bullitt County, Kentucky

    Unit 5 consists of 58 ac (23 ha) and includes two subunits, both in 
Bullitt County, Kentucky. It includes two element occurrences, 
representing the most easterly occurrences south of the Salt River. 
These subunits are important for maintaining the distribution and 
genetic diversity of the species.
    Within Unit 5, the features essential to the conservation of the 
species may require special management considerations or protection to 
address potential adverse effects associated with illegal waste dumps, 
development on private land, incompatible agricultural or grazing 
practices, ORV or horseback riding, competition from lawn grasses, and 
forest encroachment due to fire suppression.
    Subunit 5A is 8 ac (3 ha) in size and is located east of Cox Creek 
and west of KY 1442. It is in private ownership. This site is 
threatened by ORV use and would benefit from improved habitat 
management.
    Subunit 5B is 50 ac (20 ha) in size and is located west of Cox 
Creek near the Bullitt/Spencer County line. It is in private ownership. 
Incompatible agricultural practices and ORV use impacts L. exigua var. 
laciniata and may decrease its ability to persist. The native flora is 
mostly intact, and L. exigua var. laciniata would benefit from improved 
habitat management.

[[Page 25696]]

Unit 6: Rocky Run, Bullitt County, Kentucky

    Unit 6 consists of 374 ac (151 ha) in Bullitt County, Kentucky. 
This critical habitat unit includes habitat that is under private 
ownership, including one 16-acre registered natural area. It includes 
one element occurrence. This unit appears to represent the largest 
intact glade habitat remaining within the range of the species. Within 
Unit 6, the features essential to the conservation of the species may 
require special management considerations or protection to address 
potential adverse effects associated with development on private land, 
incompatible agricultural or grazing practices, competition from lawn 
grasses, and forest encroachment due to fire suppression.

Effects of Critical Habitat Designation

Section 7 Consultation

    Section 7(a)(2) of the Act requires Federal agencies, including the 
Service, to ensure that any action they fund, authorize, or carry out 
is not likely to jeopardize the continued existence of any endangered 
species or threatened species or result in the destruction or adverse 
modification of designated critical habitat of such species. In 
addition, section 7(a)(4) of the Act requires Federal agencies to 
confer with the Service on any agency action which is likely to 
jeopardize the continued existence of any species proposed to be listed 
under the Act or result in the destruction or adverse modification of 
proposed critical habitat.
    Decisions by the 5th and 9th Circuit Courts of Appeals have 
invalidated our regulatory definition of ``destruction or adverse 
modification'' (50 CFR 402.02) (see Gifford Pinchot Task Force v. U.S. 
Fish and Wildlife Service, 378 F.3d 1059 (9th Cir. 2004) and Sierra 
Club v. U.S. Fish and Wildlife Service, 245 F.3d 434 (5th Cir. 2001)), 
and we do not rely on this regulatory definition when analyzing whether 
an action is likely to destroy or adversely modify critical habitat. 
Under the provisions of the Act, we determine destruction or adverse 
modification on the basis of whether, with implementation of the 
proposed Federal action, the affected critical habitat would continue 
to serve its intended conservation role for the species.
    If a Federal action may affect a listed species or its critical 
habitat, the responsible Federal agency (action agency) must enter into 
consultation with us. Examples of actions that are subject to the 
section 7 consultation process are actions on State, tribal, local, or 
private lands that require a Federal permit (such as a permit from the 
U.S. Army Corps of Engineers under section 404 of the Clean Water Act 
(33 U.S.C. 1251 et seq.) or a permit from the Service under section 10 
of the Act) or that involve some other Federal action (such as funding 
from the Federal Highway Administration, Federal Aviation 
Administration, or the Federal Emergency Management Agency). Federal 
actions not affecting listed species or critical habitat, and actions 
on State, tribal, local, or private lands that are not federally funded 
or authorized, do not require section 7 consultation.
    As a result of section 7 consultation, we document compliance with 
the requirements of section 7(a)(2) through our issuance of:
    (1) A concurrence letter for Federal actions that may affect, but 
are not likely to adversely affect, listed species or critical habitat; 
or
    (2) A biological opinion for Federal actions that may affect and 
are likely to adversely affect, listed species or critical habitat.
    When we issue a biological opinion concluding that a project is 
likely to jeopardize the continued existence of a listed species and/or 
destroy or adversely modify critical habitat, we provide reasonable and 
prudent alternatives to the project, if any are identifiable, that 
would avoid the likelihood of jeopardy and/or destruction or adverse 
modification of critical habitat. We define ``reasonable and prudent 
alternatives'' (at 50 CFR 402.02) as alternative actions identified 
during consultation that:
    (1) Can be implemented in a manner consistent with the intended 
purpose of the action,
    (2) Can be implemented consistent with the scope of the Federal 
agency's legal authority and jurisdiction,
    (3) Are economically and technologically feasible, and
    (4) Would, in the Director's opinion, avoid the likelihood of 
jeopardizing the continued existence of the listed species and/or avoid 
the likelihood of destroying or adversely modifying critical habitat.
    Reasonable and prudent alternatives can vary from slight project 
modifications to extensive redesign or relocation of the project. Costs 
associated with implementing a reasonable and prudent alternative are 
similarly variable.
    Regulations at 50 CFR 402.16 require Federal agencies to reinitiate 
consultation on previously reviewed actions in instances where we have 
listed a new species or subsequently designated critical habitat that 
may be affected and the Federal agency has retained discretionary 
involvement or control over the action (or the agency's discretionary 
involvement or control is authorized by law). Consequently, Federal 
agencies sometimes may need to request reinitiation of consultation 
with us on actions for which formal consultation has been completed, if 
those actions with discretionary involvement or control may affect 
subsequently listed species or designated critical habitat.

Application of the ``Adverse Modification'' Standard

    The key factor related to the adverse modification determination is 
whether, with implementation of the proposed Federal action, the 
affected critical habitat would continue to serve its intended 
conservation role for the species. Activities that may destroy or 
adversely modify critical habitat are those that alter the physical or 
biological features to an extent that appreciably reduces the 
conservation value of critical habitat for L. exigua var. laciniata. As 
discussed above, the role of critical habitat is to support life-
history needs of the species and provide for the conservation of the 
species.
    Section 4(b)(8) of the Act requires us to briefly evaluate and 
describe, in any proposed or final regulation that designates critical 
habitat, activities involving a Federal action that may destroy or 
adversely modify such habitat, or that may be affected by such 
designation.
    Activities that may affect critical habitat, when carried out, 
funded, or authorized by a Federal agency, should result in 
consultation for L. exigua var. laciniata. These activities include, 
but are not limited to:
    (1) Actions within or near critical habitat that would result in 
the loss of bare or open ground. Such activities could include, but are 
not limited to: Development; road maintenance, widening, or 
construction; and utility line construction or maintenance. These 
activities could eliminate or reduce the habitat necessary for growth, 
reproduction, and/or expansion of L. exigua var. laciniata.
    (2) Actions within or near critical habitat that would modify the 
hydrologic regime that allows for the shallow soils to be very wet in 
late winter to early spring and dry quickly. Such activities could 
include, but are not limited to: Development; road maintenance, 
widening, or construction; and utility line construction or 
maintenance. These activities could alter habitat conditions to the 
point of eliminating the site conditions required

[[Page 25697]]

for growth, reproduction, and/or expansion of L. exigua var. laciniata.
    (3) Actions within or near critical habitat that would remove or 
alter vegetation and allow erosion, sedimentation, shading, or the 
introduction or expansion of invasive species. Such activities could 
include, but are not limited to: Land clearing; silviculture; 
fertilizer, herbicide, or insecticide applications; development; road 
maintenance, widening, or construction; and utility line construction 
or maintenance. These activities could alter habitat conditions to the 
point of eliminating the site conditions required for growth, 
reproduction, and/or expansion of L. exigua var. laciniata.

Exemptions

Application of Section 4(a)(3) of the Act

    Section 4(a)(3)(B)(i) of the Act (16 U.S.C. 1533(a)(3)(B)(i)) 
provides that: ``The Secretary shall not designate as critical habitat 
any lands or other geographical areas owned or controlled by the 
Department of Defense, or designated for its use, that are subject to 
an integrated natural resources management plan [INRMP] prepared under 
section 101 of the Sikes Act (16 U.S.C. 670a), if the Secretary 
determines in writing that such plan provides a benefit to the species 
for which critical habitat is proposed for designation.'' There are no 
Department of Defense lands with a completed INRMP within the critical 
habitat designation.

Consideration of Impacts Under Section 4(b)(2) of the Act

    Section 4(b)(2) of the Act states that the Secretary shall 
designate and make revisions to critical habitat on the basis of the 
best available scientific data after taking into consideration the 
economic impact, national security impact, and any other relevant 
impact of specifying any particular area as critical habitat. The 
Secretary may exclude an area from critical habitat if she determines 
that the benefits of such exclusion outweigh the benefits of specifying 
such area as part of the critical habitat, unless she determines, based 
on the best scientific data available, that the failure to designate 
such area as critical habitat will result in the extinction of the 
species. In making that determination, the statute on its face, as well 
as the legislative history, are clear that the Secretary has broad 
discretion regarding which factor(s) to use and how much weight to give 
to any factor.

Consideration of Economic Impacts

    Under section 4(b)(2) of the Act, we consider the economic impacts 
of specifying any particular area as critical habitat. In order to 
consider economic impacts, we prepared an incremental effects 
memorandum (IEM) and screening analysis which together with our 
narrative and interpretation of effects we consider our draft economic 
analysis (DEA) of the proposed critical habitat designation and related 
factors (IEc 2013). The analysis was made available for public review 
from January 7, 2014, through February 6, 2014 (79 FR 796). The DEA 
addressed potential economic impacts of critical habitat designation 
for L. exigua var. laciniata. Following the close of the comment 
period, we reviewed and evaluated all information submitted during the 
comment period that may pertain to our consideration of the probable 
incremental economic impacts of this critical habitat designation. 
Additional information relevant to the probable incremental economic 
impacts of critical habitat designation for L. exigua var. laciniata is 
summarized below and available in the screening analysis for L. exigua 
var. laciniata (IEc 2013), available at https://www.regulations.gov.
    The screening analysis addresses how probable economic impacts are 
likely to be distributed, including an assessment of any local or 
regional impacts of habitat conservation and the potential effects of 
conservation activities on government agencies, private businesses, and 
individuals. Decision-makers can use this information to evaluate 
whether the effects of the designation might unduly burden a particular 
group, area, or economic sector. The screening analysis assesses the 
economic impacts of L. exigua var. laciniata conservation efforts 
associated with the following categories of activity: Residential and 
commercial development; transportation projects; recreational 
activities; agricultural activities; utility projects; and commercial 
timber harvest.
    In general, because L. exigua var. laciniata is a narrow endemic 
species, and all of the critical habitat units are occupied by the 
species, the quality of its habitat is closely linked to the species' 
survival (USFWS 2013). Consequently, the Service believes that in most 
circumstances, there will be no conservation efforts needed to prevent 
adverse modification of critical habitat beyond those that would be 
required to prevent jeopardy to the species. Any anticipated 
incremental costs of the critical habitat designation costs will 
predominantly be administrative in nature and would not be significant. 
Critical habitat may impact property values indirectly if developers 
assume the designation will limit the potential use of that land. 
However, the designation of critical habitat is not likely to result in 
an increase of consultations, but rather only the additional 
administrative effort within each consultation to address the effects 
of each proposed agency action on critical habitat.

Exclusions Based on Economic Impacts

    Our economic analysis did not identify any disproportionate costs 
that are likely to result from the designation. Consequently, the 
Secretary is not exercising her discretion to exclude any areas from 
this designation of critical habitat for L. exigua var. laciniata based 
on economic impacts.

may be obtained by contacting the Kentucky Ecological Services Field 
Office (see ADDRESSES) or by downloading from the Internet at https://www.regulations.gov.

Exclusions Based on National Security Impacts or Homeland Security 
Impacts

    Under section 4(b)(2) of the Act, we consider whether there are 
lands owned or managed by the Department of Defense where a national 
security impact might exist. In preparing this final rule, we have 
determined that no lands within the designation of critical habitat for 
L. exigua var. laciniata are owned or managed by the Department of 
Defense or Department of Homeland Security, and, therefore, we 
anticipate no impact to national security or homeland security. 
Consequently, the Secretary is not exercising her discretion to exclude 
any areas from this final designation based on impacts to national 
security or homeland security.

Exclusions Based on Other Relevant Impacts

    Under section 4(b)(2) of the Act, we also consider any other 
relevant impacts resulting from the designation of critical habitat. We 
consider a number of factors, including whether the landowners have 
developed any HCPs or other management plans for the area, or whether 
there are conservation partnerships that would be encouraged by 
designation of, or exclusion from, critical habitat. In addition, we 
look at any tribal issues and consider the government-to-government 
relationship of the United States with tribal entities. We also 
consider any social impacts that might occur because of the 
designation.

[[Page 25698]]

    In preparing this final rule, we have determined that there are 
currently no permitted HCPs or other approved management plans for L. 
exigua var. laciniata, and the final designation does not include any 
tribal lands or trust resources. We anticipate no impact on 
partnerships or HCPs from this critical habitat designation. 
Accordingly, the Secretary is not exercising her discretion to exclude 
any areas from this final designation based on other relevant impacts.

Required Determinations

Regulatory Planning and Review (Executive Orders 12866 and 13563)

    Executive Order 12866 provides that the Office of Information and 
Regulatory Affairs (OIRA) will review all significant rules. The Office 
of Information and Regulatory Affairs has determined that this rule is 
not significant.
    Executive Order 13563 reaffirms the principles of E.O. 12866 while 
calling for improvements in the nation's regulatory system to promote 
predictability, to reduce uncertainty, and to use the best, most 
innovative, and least burdensome tools for achieving regulatory ends. 
The executive order directs agencies to consider regulatory approaches 
that reduce burdens and maintain flexibility and freedom of choice for 
the public where these approaches are relevant, feasible, and 
consistent with regulatory objectives. E.O. 13563 emphasizes further 
that regulations must be based on the best available science and that 
the rulemaking process must allow for public participation and an open 
exchange of ideas. We have developed this rule in a manner consistent 
with these requirements.

Regulatory Flexibility Act (5 U.S.C. 601 et seq.)

    Under the Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.), 
as amended by the Small Business Regulatory Enforcement Fairness Act of 
1996 (SBREFA; 5 U.S.C. 801 et seq.), whenever an agency is required to 
publish a notice of rulemaking for any proposed or final rule, it must 
prepare and make available for public comment a regulatory flexibility 
analysis that describes the effects of the rule on small entities 
(i.e., small businesses, small organizations, and small government 
jurisdictions). However, no regulatory flexibility analysis is required 
if the head of the agency certifies the rule will not have a 
significant economic impact on a substantial number of small entities. 
The SBREFA amended the RFA to require Federal agencies to provide a 
certification statement of the factual basis for certifying that the 
rule will not have a significant economic impact on a substantial 
number of small entities.
    According to the Small Business Administration, small entities 
include small organizations such as independent nonprofit 
organizations; small governmental jurisdictions, including school 
boards and city and town governments that serve fewer than 50,000 
residents; and small businesses (13 CFR 121.201). Small businesses 
include manufacturing and mining concerns with fewer than 500 
employees, wholesale trade entities with fewer than 100 employees, 
retail and service businesses with less than $5 million in annual 
sales, general and heavy construction businesses with less than $27.5 
million in annual business, special trade contractors doing less than 
$11.5 million in annual business, and agricultural businesses with 
annual sales less than $750,000. To determine if potential economic 
impacts to these small entities are significant, we considered the 
types of activities that might trigger regulatory impacts under this 
designation as well as types of project modifications that may result. 
In general, the term ``significant economic impact'' is meant to apply 
to a typical small business firm's business operations.
    The Service's current understanding of the requirements under the 
RFA, as amended, and following recent court decisions, is that Federal 
agencies are only required to evaluate the potential incremental 
impacts of rulemaking on those entities directly regulated by the 
rulemaking itself, and therefore, not required to evaluate the 
potential impacts to indirectly regulated entities. The regulatory 
mechanism through which critical habitat protections are realized is 
section 7 of the Act, which requires Federal agencies, in consultation 
with the Service, to ensure that any action authorized, funded, or 
carried by the agency is not likely to destroy or adversely modify 
critical habitat. Therefore, under section 7 only Federal action 
agencies are directly subject to the specific regulatory requirement 
(avoiding destruction and adverse modification) imposed by critical 
habitat designation. Consequently, it is our position that only Federal 
action agencies will be directly regulated by this designation. There 
is no requirement under RFA to evaluate the potential impacts to 
entities not directly regulated. Moreover, Federal agencies are not 
small entities. Therefore, because no small entities are directly 
regulated by this rulemaking, the Service certifies that this final 
critical habitat designation will not have a significant economic 
impact on a substantial number of small entities.
    During the development of this final rule, we reviewed and 
evaluated all information submitted during the comment period that may 
pertain to our consideration of the probable incremental economic 
impacts of this critical habitat designation. Based on this 
information, we affirm our certification that this final critical 
habitat designation will not have a significant economic impact on a 
substantial number of small entities, and a regulatory flexibility 
analysis is not required.

Energy Supply, Distribution, or Use--Executive Order 13211

    Executive Order 13211 (Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use) requires 
agencies to prepare Statements of Energy Effects when undertaking 
certain actions. OMB has provided guidance for implementing this 
Executive Order that outlines nine outcomes that may constitute ``a 
significant adverse effect'' when compared to not taking the regulatory 
action under consideration.
    The DEA finds that none of these criteria is relevant to this 
analysis. Thus, based on information in the economic analysis, energy-
related impacts associated with L. exigua var. laciniata conservation 
activities within critical habitat are not expected. As such, the 
designation of critical habitat is not expected to significantly affect 
energy supplies, distribution, or use. Therefore, this action is not a 
significant energy action, and no Statement of Energy Effects is 
required.

Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)

    In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501 
et seq.), we make the following findings:
    (1) This rule will not produce a Federal mandate. In general, a 
Federal mandate is a provision in legislation, statute, or regulation 
that would impose an enforceable duty upon State, local, or tribal 
governments, or the private sector, and includes both ``Federal 
intergovernmental mandates'' and ``Federal private sector mandates.'' 
These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal 
intergovernmental mandate'' includes a regulation that ``would impose 
an enforceable duty upon State, local, or tribal governments'' with two 
exceptions. It excludes ``a condition of Federal assistance.'' It also 
excludes ``a duty arising from participation in a voluntary Federal

[[Page 25699]]

program,'' unless the regulation ``relates to a then-existing Federal 
program under which $500,000,000 or more is provided annually to State, 
local, and tribal governments under entitlement authority,'' if the 
provision would ``increase the stringency of conditions of assistance'' 
or ``place caps upon, or otherwise decrease, the Federal Government's 
responsibility to provide funding,'' and the State, local, or tribal 
governments ``lack authority'' to adjust accordingly. At the time of 
enactment, these entitlement programs were: Medicaid; Aid to Families 
with Dependent Children work programs; Child Nutrition; Food Stamps; 
Social Services Block Grants; Vocational Rehabilitation State Grants; 
Foster Care, Adoption Assistance, and Independent Living; Family 
Support Welfare Services; and Child Support Enforcement. ``Federal 
private sector mandate'' includes a regulation that ``would impose an 
enforceable duty upon the private sector, except (i) a condition of 
Federal assistance or (ii) a duty arising from participation in a 
voluntary Federal program.''
    The designation of critical habitat does not impose a legally 
binding duty on non-Federal Government entities or private parties. 
Under the Act, the only regulatory effect is that Federal agencies must 
ensure that their actions do not destroy or adversely modify critical 
habitat under section 7. While non-Federal entities that receive 
Federal funding, assistance, or permits, or that otherwise require 
approval or authorization from a Federal agency for an action, may be 
indirectly impacted by the designation of critical habitat, the legally 
binding duty to avoid destruction or adverse modification of critical 
habitat rests squarely on the Federal agency. Furthermore, to the 
extent that non-Federal entities are indirectly impacted because they 
receive Federal assistance or participate in a voluntary Federal aid 
program, the Unfunded Mandates Reform Act would not apply, nor would 
critical habitat shift the costs of the large entitlement programs 
listed above onto State governments.
    (2) We do not believe that this rule will significantly or uniquely 
affect small governments because it will not produce a Federal mandate 
of $100 million or greater in any year, that is, it is not a 
``significant regulatory action'' under the Unfunded Mandates Reform 
Act. Small governments will be affected only to the extent that any 
programs having Federal funds, permits, or other authorized activities 
must ensure that their actions will not adversely affect the critical 
habitat. The final economic analysis concludes incremental impacts may 
occur due to administrative costs of section 7 consultations for 
activities related to commercial, residential, and recreational 
development and associated actions; however, these are not expected to 
significantly affect small government entities. Consequently, a Small 
Government Agency Plan is not required.

Takings--Executive Order 12630

    In accordance with Executive Order 12630 (``Government Actions and 
Interference with Constitutionally Protected Private Property 
Rights''), we have analyzed the potential takings implications of 
designating critical habitat for L. exigua var. laciniata in a takings 
implications assessment. As discussed above, the designation of 
critical habitat affects only Federal actions. Although private parties 
that receive Federal funding, assistance, or require approval or 
authorization from a Federal agency for an action may be indirectly 
impacted by the designation of critical habitat, the legally binding 
duty to avoid destruction or adverse modification of critical habitat 
rests squarely on the Federal agency. The DEA found that no significant 
economic impacts are likely to result from the designation of critical 
habitat for L. exigua var. laciniata. Because the Act's critical 
habitat protection requirements apply only to Federal agency actions, 
few conflicts between critical habitat and private property rights 
should result from this designation. Based on the best available 
information, the takings implications assessment concludes that this 
designation of critical habitat for L. exigua var. laciniata does not 
pose significant takings implications.

Federalism--Executive Order 13132

    In accordance with E.O. 13132 (Federalism), this rule does not have 
significant Federalism effects. A federalism summary impact statement 
is not required. In keeping with Department of the Interior and 
Department of Commerce policy, we requested information from, and 
coordinated development of this critical habitat designation with, 
appropriate State resource agencies in Kentucky. We received comments 
from the Kentucky State Nature Preserves Commission and have addressed 
them in the Summary of Comments and Recommendations section of the 
rule. From a federalism perspective, the designation of critical 
habitat directly affects only the responsibilities of Federal agencies. 
The Act imposes no other duties with respect to critical habitat, 
either for States and local governments, or for anyone else. As a 
result, the rule does not have substantial direct effects either on the 
States, or on the relationship between the national government and the 
States, or on the distribution of powers and responsibilities among the 
various levels of government. The designation may have some benefit to 
these governments because the areas that contain the features essential 
to the conservation of the species are more clearly defined, and the 
physical and biological features of the habitat necessary to the 
conservation of the species are specifically identified. This 
information does not alter where and what federally sponsored 
activities may occur. However, it may assist these local governments in 
long-range planning (because these local governments no longer have to 
wait for case-by-case section 7 consultations to occur).
    Where State and local governments require approval or authorization 
from a Federal agency for actions that may affect critical habitat, 
consultation under section 7(a)(2) would be required. While non-Federal 
entities that receive Federal funding, assistance, or permits, or that 
otherwise require approval or authorization from a Federal agency for 
an action, may be indirectly impacted by the designation of critical 
habitat, the legally binding duty to avoid destruction or adverse 
modification of critical habitat rests squarely on the Federal agency.

Civil Justice Reform--Executive Order 12988

    In accordance with Executive Order 12988 (Civil Justice Reform), 
the Office of the Solicitor has determined that the rule does not 
unduly burden the judicial system and that it meets the applicable 
standards set forth in sections 3(a) and 3(b)(2) of the Order. We are 
designating critical habitat in accordance with the provisions of the 
Act. To assist the public in understanding the habitat needs of the 
species, the rule identifies the elements of physical or biological 
features essential to the conservation of L. exigua var. laciniata. The 
designated areas of critical habitat are presented on maps, and the 
rule provides several options for the interested public to obtain more 
detailed location information, if desired.

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)

    This rule does not contain any new collections of information that 
require approval by OMB under the Paperwork Reduction Act of 1995 (44 
U.S.C. 3501 et seq.). This rule will not impose recordkeeping or 
reporting requirements on State or local governments,

[[Page 25700]]

individuals, businesses, or organizations. An agency may not conduct or 
sponsor, and a person is not required to respond to, a collection of 
information unless it displays a currently valid OMB control number.

National Environmental Policy Act (42 U.S.C. 4321 et seq.)

    It is our position that, outside the jurisdiction of the U.S. Court 
of Appeals for the Tenth Circuit, we do not need to prepare 
environmental analyses pursuant to NEPA in connection with designating 
critical habitat under the Act. We published a notice outlining our 
reasons for this determination in the Federal Register on October 25, 
1983 (48 FR 49244). This position was upheld by the U.S. Court of 
Appeals for the Ninth Circuit (Douglas County v. Babbitt, 48 F.3d 1495 
(9th Cir. 1995), cert. denied 516 U.S. 1042 (1996)).

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. As stated above, we are not 
designating critical habitat for L. exigua var. laciniata on tribal 
lands.

    (1) Critical habitat units are depicted for Bullitt and Jefferson 
Counties, Kentucky, on the maps below.
    (2) Within these areas, the primary constituent elements of the 
physical or biological features essential to the conservation of L. 
exigua var. laciniata consist of these components:
    (i) Cedar glades and gladelike areas within the range of L. exigua 
var. laciniata that include:
    (A) Areas of rock outcrop, gravel, flagstone of Silurian dolomite 
or dolomitic limestone, and/or shallow (1 to 5 centimeters (0.393 to 
1.97 inches)), calcareous soils;
    (B) Intact cyclic hydrologic regime involving saturation and/or 
inundation of the area in winter and early spring, then drying quickly 
in the summer;
    (C) Full or nearly full sunlight; and
    (D) An undisturbed seed bank.
    (ii) Vegetated land around glades and gladelike areas that extends 
up and down slope and ends at natural (e.g., stream, topographic 
contours) or manmade breaks (e.g., roads).
    (3) Critical habitat does not include manmade structures (such as 
buildings, aqueducts, runways, roads, and other paved areas) and the 
land on which they are located existing within the legal boundaries on 
June 5, 2014.
    (4) Critical habitat map units. Data layers defining critical 
habitat map units were created using a base of aerial photographs (USDA 
National Agricultural Imagery Program; NAIP 2010), and USA Topo Maps 
(National Geographic Society 2011). Critical habitat units were then 
mapped using Universal Transverse Mercator (UTM) Zone 16 North American 
Datum (NAD) 1983 coordinates. The maps in this entry, as modified by 
any accompanying regulatory text, establish the boundaries of the 
critical habitat designation. The coordinates or plot points or both on 
which each map is based are available to the public at the Service's 
Internet site, at https://www.regulations.gov at Docket No. FWS-R4-ES-
