                Endangered and Threatened Wildlife and Plants; Designation of
                Critical Habitat for Barrens Topminnow
                AGENCY: Fish and Wildlife Service, Interior.
                ACTION: Proposed rule.
                -----------------------------------------------------------------------
                SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to
                designate critical habitat for the Barrens topminnow (Fundulus julisia)
                under the Endangered Species Act of 1973, as amended (Act). In total,
                approximately 1.5 acres (0.6 hectares) of spring pool and 11.4 miles
                (18.3 kilometers) of spring run in Cannon, Coffee, Dekalb, Franklin,
                Grundy, and Warren Counties, Tennessee, fall within the boundaries of
                the proposed critical habitat designation. We also announce the
                availability of an economic analysis of the proposed designation of
                critical habitat for the Barrens topminnow.

                SUPPLEMENTARY INFORMATION:
                Executive Summary
                 Why we need to publish a rule. To the maximum extent prudent and
                determinable, we must designate critical habitat for any species that
                we determine to be an endangered or threatened species under the Act.
                Designation of critical habitat can only be completed by issuing a rule
                through the Administrative Procedure Act rulemaking process (5 U.S.C.
                551 et seq.).
                 What this document does. We propose the designation of critical
                habitat for the Barrens topminnow. The Barrens topminnow was listed as
                an endangered species under the Act on November 20, 2019 (see 84 FR
                56131; October 21, 2019).
                 The basis for our action. Under section 4(a)(3) of the Act, if we
                determine that a species is an endangered or threatened species we
                must, to the maximum extent prudent and determinable, designate
                critical habitat. Section 3(5)(A) of the Act defines critical habitat
                as (i) the specific areas within the geographical area occupied by the
                species, at the time it is listed, on which are found those physical or
                biological features (I) essential to the conservation of the species
                and (II) which may require special management considerations or
                protections; and (ii) specific areas outside the geographical area
                occupied by the species at the time it is listed, upon a determination
                by the Secretary of the Interior (Secretary) that such areas are
                essential for the conservation of the species. Section 4(b)(2) of the
                Act states that the Secretary must make the designation on the basis of
                the best scientific data available and after taking into consideration
                the economic impact, the impact on national security, and any other
                relevant impacts of specifying any particular area as critical habitat.
                 Section 4(a)(3) of the Act and implementing regulations (50 CFR
                424.12) require that we designate critical habitat at the time a
                species is determined to be an endangered or threatened species, to the
                maximum extent prudent and determinable. On January 4, 2018, the
                Service published a proposed rule to list the Barrens topminnow as an
                endangered species under the Act (83 FR 490). At the time of the
                proposed listing rule, the Service found that critical habitat was
                prudent but could not be determined until a careful assessment of the
                economic impacts that may occur due to a critical habitat designation
                was completed. The final listing rule (84 FR 56131; October 21, 2019)
                affirmed that the designation of critical habitat was prudent but not
                determinable because specific information needed to analyze the impacts
                of designation was lacking.
                 In accordance with section 4(b)(2) of the Act and our implementing
                regulations at 50 CFR 424.19, we prepared an analysis of the economic
                impacts of the proposed critical habitat designation. In this proposed
                rule, we announce the availability of the draft economic analysis for
                public review and comment.
                Peer Review
                 In accordance with our joint policy on peer review published in the
                Federal Register on July 1, 1994 (59 FR 34270) and our August 22, 2016,
                memorandum updating and clarifying the role of peer review of listing
                actions under the Act, we sought the expert opinions of appropriate
                specialists regarding our 2017 species status assessment (SSA) report
                (Service 2017, entire), which informed this proposed rule. In addition
                to the peer review conducted on the 2017 SSA report, we are seeking
                comments from independent specialists during the public comment period
                on this proposed rule (see DATES, above). The purpose of peer review is
                to ensure that our designation is based on scientifically sound data,
                assumptions, and analyses. The peer reviewers have expertise in fish
                biology, habitat, and stressors or factors negatively affecting the
                species.
                Information Requested
                 We intend that any final action resulting from this proposed rule
                will be based on the best scientific data available and be as accurate
                and as effective as possible. Therefore, we request comments or
                information from other governmental agencies, Native American Tribes,
                the scientific community, industry, or any other interested parties
                concerning this proposed rule. We particularly seek comments
                concerning:
                 (1) Historical and current range, including distribution patterns
                and the locations of any additional populations of Barrens topminnow.
                 (2) Specific information on:
                 (a) The amount and distribution of Barrens topminnow habitat;
                 (b) Any additional areas occurring within the range of the species,
                i.e., Cannon, Coffee, Dekalb, Franklin, Grundy, and Warren Counties,
                Tennessee, that should be included in the designation because they (i)
                are occupied at the time of listing and contain the physical or
                biological features that are essential to the conservation of the
                species and that may require special management considerations or
                protection, or (ii) are unoccupied at the time of listing and are
                essential for the conservation of the species;
                 (c) Special management considerations or protection that may be
                needed in critical habitat areas we are proposing, including managing
                for the potential effects of climate change; and
                 (d) Whether areas not occupied at the time of listing qualify as
                habitat for the species and are essential for the conservation of the
                species.
                 (3) Land use designations and current or planned activities in the
                subject areas and their possible impacts on proposed critical habitat.
                 (4) Any probable economic, national security, or other relevant
                impacts of designating any area that may be included in the final
                designation, and the related benefits of including or excluding
                specific areas.
                 (5) Information on the extent to which the description of probable
                economic impacts in the draft economic analysis is a reasonable
                estimate of the likely economic impacts.
                 (6) Whether any specific areas we are proposing for critical
                habitat designation should be considered for exclusion under section
                4(b)(2) of the Act, and whether the benefits of potentially excluding
                any specific area outweigh the benefits of including that area under
                section 4(b)(2) of the Act. Please see Consideration of Other Relevant
                Impacts, below, for information on areas for which the Service's
                Partners for Fish and Wildlife is developing conservation agreements;
                if you think we should exclude any of these areas, or any other areas,
                from the designation of critical habitat for the Barrens topminnow,
                please provide information supporting a benefit of exclusion.
                 (7) Whether we could improve or modify our approach to designating
                critical habitat in any way to provide for greater public participation
                and understanding, or to better accommodate public concerns and
                comments.
                 Please include sufficient information with your submission (such as
                scientific journal articles or other publications) to allow us to
                verify any scientific or commercial information you include.
                 Please note that submissions merely stating support for, or
                opposition to, the action under consideration without providing
                supporting information, although noted, do not provide substantial
                information necessary to support a determination. Section 4(b)(2) of
                the Act directs that the Secretary
                [[Page 56255]]
                shall designate critical habitat on the basis of the best scientific
                data available.
                 You may submit your comments and materials concerning this proposed
                rule by one of the methods listed in ADDRESSES. We request that you
                send comments only by the methods described in ADDRESSES.
                 If you submit information via https://www.regulations.gov, your
                entire submission--including any personal identifying information--will
                be posted on the website. If your submission is made via a hardcopy
                that includes personal identifying information, you may request at the
                top of your document that we withhold this information from public
                review. However, we cannot guarantee that we will be able to do so. We
                will post all hardcopy submissions on https://www.regulations.gov.
                 Comments and materials we receive, as well as supporting
                documentation we used in preparing this proposed rule, will be
                available for public inspection on https://www.regulations.gov.
                 Our final critical habitat designation may differ from this
                proposal because we will consider all comments we receive during the
                comment period as well as any information that may become available
                after this proposal. Our final designation may not include all areas
                proposed if we determine they do not meet the definition of critical
                habitat, may include some additional areas that meet the definition of
                critical habitat, or may exclude some areas if we find the benefits of
                exclusion outweigh the benefits of inclusion and exclusion will not
                result in the extinction of the species. In our final rule, we will
                clearly explain our rationale and the basis for our final decision,
                including why we made changes, if any, that differ from this proposal.
                Public Hearing
                 Section 4(b)(5) of the Act provides for a public hearing on this
                proposal, if requested. Requests must be received by the date specified
                in DATES. Such requests must be sent to the address shown in FOR
                FURTHER INFORMATION CONTACT. We will schedule a public hearing on this
                proposal, if requested, and announce the date, time, and place of the
                hearing, as well as how to obtain reasonable accommodations, in the
                Federal Register and local newspapers at least 15 days before the
                hearing. We may hold the public hearing in person or virtually via
                webinar. We will announce any public hearing on our website, in
                addition to the Federal Register. The use of virtual public hearings is
                consistent with our regulations at 50 CFR 424.16(c)(3).
                Previous Federal Actions
                 On January 4, 2018, we published a proposed rule in the Federal
                Register (83 FR 490) to list the Barrens topminnow as an endangered
                species under the Act. At the time of our proposal, we determined that
                designation of critical habitat was prudent but not determinable
                because specific information needed to analyze the impacts of
                designation was lacking. We published the final listing rule on October
                21, 2019 (84 FR 56131). Please refer to the proposed and final listing
                rules (83 FR 490, January 4, 2018; 84 FR 56131, October 21, 2019) for a
                detailed description of previous Federal actions concerning this
                freshwater fish species.
                Background
                Critical Habitat
                 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.
                 Our regulations at 50 CFR 424.02 define the geographical area
                occupied by the species as an area that may generally be delineated
                around species' occurrences, as determined by the Secretary (i.e.,
                range). Such areas may include those areas used throughout all or part
                of the species' life cycle, even if not used on a regular basis (e.g.,
                migratory corridors, seasonal habitats, and habitats used periodically,
                but not solely by vagrant individuals).
                 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. Rather, designation requires that, where a
                landowner requests Federal agency funding or authorization for an
                action that may affect an area designated as critical habitat, the
                Federal agency consult with the Service under section 7(a)(2) of the
                Act. If the action may affect the listed species itself (such as for
                occupied critical habitat), the Federal agency would have already been
                required to consult with the Service even absent the designation
                because of the requirement to ensure that the action is not likely to
                jeopardize the continued existence of the species. Even if the Service
                were to conclude after consultation that the proposed activity is
                likely to result in destruction or adverse modification of the critical
                habitat, the Federal action agency and the landowner are not required
                to abandon the proposed activity, or to restore or recover the species;
                instead, they must 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 data available, those physical or biological features that
                are essential to the conservation of the species (such as space, food,
                cover, and protected habitat).
                 Under the second prong of the Act's definition of critical habitat,
                we can designate critical habitat in areas outside the geographical
                area occupied
                [[Page 56256]]
                by the species at the time it is listed, upon a determination that such
                areas are essential for the conservation of the species.
                 Section 4 of the Act requires that we designate critical habitat on
                the basis of the best scientific 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 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 from the SSA report and information developed during the
                listing process for the species. Additional information sources may
                include any generalized conservation strategy, criteria, or outline
                that may have been developed for the species; 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 ensure their actions are not likely to
                jeopardize the continued existence of any endangered or threatened
                species; and (3) the prohibitions found in section 9 of the Act.
                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 the 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 those planning efforts calls for a
                different outcome.
                Physical or Biological Features Essential to the Conservation of the
                Species
                 In accordance with section 3(5)(A)(i) of the Act and regulations at
                50 CFR 424.12(b), in determining which areas we will designate as
                critical habitat from within the geographical area occupied by the
                species at the time of listing, we consider the physical or biological
                features that are essential to the conservation of the species and
                which may require special management considerations or protection. The
                regulations at 50 CFR 424.02 define ``physical or biological features
                essential to the conservation of the species'' as the features that
                occur in specific areas and that are essential to support the life-
                history needs of the species, including, but not limited to, water
                characteristics, soil type, geological features, sites, prey,
                vegetation, symbiotic species, or other features. A feature may be a
                single habitat characteristic or a more complex combination of habitat
                characteristics. Features may include habitat characteristics that
                support ephemeral or dynamic habitat conditions. Features may also be
                expressed in terms relating to principles of conservation biology, such
                as patch size, distribution distances, and connectivity. For example,
                physical features essential to the conservation of the species might
                include gravel of a particular size required for spawning, alkaline
                soil for seed germination, protective cover for migration, or
                susceptibility to flooding or fire that maintains necessary early-
                successional habitat characteristics. Biological features might include
                prey species, forage grasses, specific kinds or ages of trees for
                roosting or nesting, symbiotic fungi, or absence of a particular level
                of nonnative species consistent with conservation needs of the listed
                species. The features may also be combinations of habitat
                characteristics and may encompass the relationship between
                characteristics or the necessary amount of a characteristic essential
                to support the life history of the species.
                 In considering whether features are essential to the conservation
                of the species, we may consider an appropriate quality, quantity, and
                spatial and temporal arrangement of habitat characteristics in the
                context of the life-history needs, condition, and status of the
                species. These characteristics include, but are not limited to, space
                for individual and population growth and for normal behavior; food,
                water, air, light, minerals, or other nutritional or physiological
                requirements; cover or shelter; sites for breeding, reproduction, or
                rearing (or development) of offspring; and habitats that are protected
                from disturbance.
                Summary of Essential Physical or Biological Features
                 We derive the specific physical or biological features essential to
                the conservation of Barrens topminnow from studies of this species'
                habitat, ecology, and life history as described in the SSA report
                (Service 2017, entire); January 4, 2018, proposed listing rule (83 FR
                490); and October 21, 2019, final listing rule (84 FR 56131). As
                described in the SSA report and listing rules, Barrens topminnows spawn
                in filamentous algae near the water surface, between April and August,
                with peak activity occurring from May to June. While the maximum age of
                the Barrens topminnow is 4 years, adults typically live for 2 years or
                less, and only about one-third of individuals spawn more than one
                season (Rakes 1989, p. 42; Etnier and Starnes 1993, p. 366). Prey items
                consumed by Barrens topminnows consist predominantly of
                microcrustaceans and immature aquatic insect larvae. However, the
                species is a generalist feeder, also consuming small snails and
                terrestrial organisms such as ants and other insects that fall or
                wander into aquatic habitats (Rakes 1989, pp. 18-25).
                 Barrens topminnow habitat is restricted to springhead pools and
                slow-flowing areas of spring runs on the Barrens Plateau in middle
                Tennessee. This species is known to have occurred historically at 18
                sites, but likely occurred at more sites that were not surveyed prior
                to topminnow extirpation. These fish are strongly associated with
                abundant native aquatic vegetation, which they use for cover and as
                spawning substrate (Service 2017, pp. 7-9). Spawning occurs primarily
                over clumps of filamentous algae (Cladophora and Pithophora species).
                Recently deposited eggs are nearly
                [[Page 56257]]
                colorless and well camouflaged among the many air bubbles generated
                during photosynthesis and trapped in the algae (Rakes 1989, pp. 29-30).
                In addition to clumps of algae, plants used by Barrens topminnows for
                cover include watercress (Nasturtium officinale), rushes (Juncus),
                pondweed (Potamogeton), and eelgrass (Valisneria) (Service 2017, p. 7).
                Barrens topminnows have only been found in streams where the
                predominant source of base flow is groundwater. Due to the groundwater
                influence of these habitats, temperatures are relatively stable,
                ranging from 15 to 25 degrees Celsius ([deg]C) (59 to 77 degrees
                Fahrenheit ([deg]F)) (Service, p. 7). Barrens topminnows only occur in
                and are adapted to surface streams predominantly fed by adjacent
                groundwater sources and typically are clear during baseflow. In
                unaltered landscapes, turbidity increases in these streams are
                temporary, resulting from inputs of sediments and nutrients in runoff
                following precipitation events. Because Barrens topminnows are adapted
                to clear groundwater-fed streams, use visual cues such as sunlight and
                male coloration (Rakes 1989, p. 35) for spawning, and rely in part on
                eyesight to chase prey (Rakes 1989, p. 18), long periods of elevated
                turbidity may negatively impact populations.
                 The primary habitat elements that influence resiliency of the
                Barrens topminnow include water quality, water persistence, and
                submerged or overhanging plant cover. We have determined that the
                following physical or biological features are essential to the
                conservation of the Barrens topminnow:
                 (1) Groundwater-fed, first or second order streams and springs that
                persist annually;
                 (2) Water temperature ranging from 15 to 25 [deg]C (59 to 77
                [deg]F);
                 (3) Water during base flow with limited turbidity that is
                sufficiently clear for individuals to see spawning and feeding cues;
                 (4) Submerged native aquatic plants, such as Cladophora and
                Pithophora species, watercress (Nasturtium officinale), rushes (Juncus
                spp.), pondweed (Potamogeton spp.), and eelgrass (Vallisneria spp.), or
                overhanging terrestrial plants and submerged plant roots, to provide
                cover and surfaces for spawning; and
                 (5) A prey base of microcrustaceans and small aquatic insects such
                as chironomids (midges).
                Special Management Considerations
                 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 which are essential to the conservation of
                the species and which may require special management considerations or
                protection. The features essential to the conservation of the Barrens
                topminnow may require special management considerations or protection
                to reduce the following threats: (1) Landscape conversion, including
                (but not limited to) urban, commercial, and agricultural use, and
                infrastructure (roads, bridges, utilities); (2) urban and agricultural
                water uses (water supply reservoirs, wastewater treatment, etc.); (3)
                significant alteration of water quality; (4) impacts from invasive
                species; and (5) changes and shifts in seasonal precipitation patterns
                as a result of climate change.
                 Management activities that could help ameliorate these threats
                include, but are not limited to, the following: (1) Use of best
                management practices to limit or reduce sedimentation (suspended
                sediment influxes), such as those provided in the Tennessee Department
                of Environment and Conservation (TDEC) Erosion and Sediment Control
                Handbook (TDEC 2012, entire); (2) retention of natural barriers, and
                maintenance or construction of barriers that isolate Barrens topminnows
                from invasive mosquitofish; and (3) installation of wells to provide a
                groundwater source of surface water at drought-sensitive sites.
                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 specific areas within the geographical area
                occupied by the species at the time of listing and any specific areas
                outside the geographical area occupied by the species to be considered
                for designation as critical habitat. We are proposing to designate
                critical habitat in areas within the geographical area occupied by the
                species at the time of listing. We also are proposing to designate one
                specific area outside the geographical area occupied by the species
                because we have determined that the area are is essential for the
                conservation of the species (see Areas Outside the Geographic Area
                Occupied at the Time of Listing, below).
                 The Barrens topminnow has a naturally limited range, and its
                current distribution is much reduced from its historical distribution.
                Meeting the conservation and recovery needs of the species will require
                continued protection of existing populations and habitat, as well as
                management to ensure there are adequate numbers of individuals in
                stable populations at sites in native watersheds where mosquitofish
                are, or can be, excluded. This approach will reduce the likelihood that
                catastrophic events, such as extreme droughts or introduction/invasion
                of mosquitofish at an occupied site, do not simultaneously affect all
                known populations to the same extent. In addition, rangewide recovery
                considerations, such as maintaining existing genetic diversity and
                striving for representation of all major portions of the species'
                current range, were considered in formulating this proposed critical
                habitat designation.
                Areas Occupied at the Time of Listing
                 We identified all spring pools (pond-like, with little or no flow)
                and spring runs (groundwater-fed, flowing surface water) that supported
                populations of the Barrens topminnow at the time of listing. Rangewide
                sampling undertaken at 37 spring sites since 2013 (Tennessee Aquarium
                Conservation Institute (TNACI) 2014, p. 11; TNACI 2017, p. 3) verified
                the current occurrence of Barrens topminnow at six sites (Service 2017,
                p. 12): Benedict Spring, Big Spring (Merkle), McMahan Creek, Marcum
                Spring, Short Spring, and Greenbrook Pond. The species has been shown
                in intermittent surveys over several decades to persist at these sites.
                 In 2023, a population of Barrens topminnow was discovered in Pepper
                Hollow Branch, Grundy County, Tennessee. At the time of listing in
                2019, Barrens topminnows were not known to occupy Pepper Hollow Branch.
                This stream is at the eastern edge of the Barrens Plateau and has not
                been well surveyed. Given this stream's proximity to the previously
                known range of the Barrens topminnow and, until recently, scarcity of
                reported fish surveys, it is very likely the newly discovered
                population is native and was not introduced after the time of listing.
                As such, there is little uncertainty that Barrens topminnows were
                present in Pepper Hollow Branch at the time of listing, and we include
                the stream in our proposed critical habitat designation. Mosquitofish
                are not present in Pepper Hollow Branch, although no barriers to
                potential mosquitofish incursions have been observed. This area also
                increases the species' viability, which is essential for the
                conservation of the Barrens topminnow. All five physical or biological
                features essential to the conservation of the species are present in
                Pepper Hollow Branch.
                [[Page 56258]]
                 One occupied site, Greenbrook Pond, contains an introduced
                population (present at the time of listing) outside the historical
                range of the species, but within the middle portion of the Caney Fork
                River watershed, the upper portions of which are in the species'
                historical range. All sites occupied at the time of listing (Benedict
                Spring, Big Spring (Merkle), McMahan Creek, Marcum Spring, Short
                Spring, Greenbrook Pond, and Pepper Hollow Branch) currently have all
                five essential physical or biological features for Barrens topminnow
                populations. Importantly, all occupied sites except Big Spring (Merkle)
                are currently free of mosquitofish, and five of the six sites without
                mosquitofish have a barrier to mosquitofish invasion. Barrens
                topminnows were thought to be potentially extirpated from Big Spring
                (Merkle) but were re-documented at this site on February 16, 2018
                (captured and released on February 15, 2018) (Neely 2018, pers. comm.).
                Although Big Spring (Merkle) is not free of mosquitofish and lacks a
                barrier to further mosquitofish invasion, topminnows in the spring
                appear to outnumber mosquitofish.
                Areas Outside the Geographic Area Occupied at the Time of Listing
                 We are proposing to designate one area outside the geographical
                area occupied at the time of listing by the species, Vervilla Spring
                because the area is essential for the conservation of the Barrens
                topminnow. Although it is not currently occupied, Vervilla Spring is
                within the Caney Fork River watershed where native populations of the
                Barrens topminnow occur. Vervilla Spring is on the Tennessee National
                Wildlife Refuge and sustained a population of introduced Caney Fork
                watershed Barrens topminnows from 2001 until 2011. However, the
                population succumbed to mosquitofish that, during a flood, circumvented
                a constructed barrier. It is feasible to remove all mosquitofish and
                rebuild the barrier so that it is more robust. With a strong barrier to
                mosquitofish in place, restocking can occur, establishing a new
                population. Reestablishing the population would increase Barrens
                topminnow redundancy, resiliency, and viability, promoting conservation
                and increasing the likelihood species recovery. Without the habitat
                provided by the unoccupied area, species recovery and conservation are
                less likely to be attained. All five physical or biological features
                essential to Barrens topminnow conservation are present in Vervilla
                Spring, which is habitat for the species because it provides adequate
                cover from predation, food resources, substrate (aquatic vegetation)
                for successful spawning and recruitment, and water quality that meets
                the species' physiological needs. The upper ends of all proposed
                critical habitat units are demarcated by the place where surface water
                emerges from the ground to form the head of the spring, or where
                permanent flow begins, which is approximately the location of the
                upstream-most record of Barrens topminnow in each proposed unit. Except
                for Big Spring (Merkle) and Pepper Hollow Branch, the downstream ends
                of the proposed units are demarcated by a barrier to mosquitofish. The
                downstream ends of critical habitat at Big Spring (Merkle) and Pepper
                Hollow Branch are approximately the location of the downstream-most
                record of Barrens topminnow.
                 When determining proposed 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
                the essential physical or biological features. 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 proposed rule have been excluded
                by text in the proposed rule and are not proposed for designation as
                critical habitat. Therefore, if the critical habitat is finalized as
                proposed, a Federal action involving these lands would 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 proposed critical habitat designation is defined by the map or
                maps, as modified by any accompanying regulatory text, presented at the
                end of this document under Proposed Regulation Promulgation. All
                proposed units contain all of the identified physical or biological
                features and support multiple life-history processes. 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-
                2023-0224, on our internet site (https://www.fws.gov/office/tennessee-ecological-services), and at the field office responsible for the
                designation (see FOR FURTHER INFORMATION CONTACT, above).
                Proposed Critical Habitat Designation
                 We propose to designate approximately 1.5 acres (ac) (0.6 hectares
                (ha)) of spring pool and 11.4 miles (mi) (18.3 kilometers (km)) of
                spring run in eight units as critical habitat for the Barrens
                topminnow. The table below shows the name, land ownership of the
                riparian areas surrounding the units, and surface area (for spring
                pools) or length (for stream runs) of the proposed units. Ownership of
                spring run and spring pool bottoms is determined by the adjacent
                riparian land ownership. These riparian areas are not part of the
                proposed critical habitat designation.

                [[Page 56259]]
                 We present brief descriptions of the proposed units, and reasons
                why they meet the definition of critical habitat for Barrens topminnow,
                below.
                Unit 1: McMahan Creek
                 Unit 1, a spring run, consists of 0.8 mi (1.3 km) of McMahan Creek
                in Cannon County. The upstream end of the unit is at the confluence of
                the source spring run (unnamed) and McMahan Creek, just north of the
                Woodland Estates subdivision. The downstream end is to the south, where
                McMahan Creek goes under Geedsville Road. This unit was occupied at the
                time of listing and is currently occupied by the Barrens topminnow. In
                addition, the unit currently supports all breeding, feeding, and
                sheltering needs for the species and contains all of the physical or
                biological features essential to the conservation of the Barrens
                topminnow. The riparian land adjacent to the unit is privately owned.
                 Special management considerations or protection may be required to
                address sediment washing into the creek from adjacent pasture and
                residential areas. Fencing would reduce the likelihood of livestock
                trampling instream vegetation, although adjacent lands are used for
                grazing only intermittently. A concrete box culvert at the Geedsville
                Road crossing at the downstream end of the unit is a barrier to
                mosquitofish. Any future roadway maintenance or construction at the
                crossing would require leaving the culvert intact or, in the case of
                culvert replacement or modification, ensuring an alternative barrier
                persists to prevent mosquitofish invasion.
                Unit 2: Benedict Spring
                 Unit 2 is a 0.1-ac (0.04-ha) spring pool in Coffee County, just
                north of Highway 55, between Summitville Road to the west and Summit
                Breeze Lane to the east. This unit was occupied at the time of listing
                and is currently occupied by the Barrens topminnow. In addition, the
                unit currently supports all breeding, feeding, and sheltering needs for
                the species and contains all of the physical or biological features
                essential to the conservation of the Barrens topminnow. The riparian
                land adjacent to the unit is privately owned.
                 Special management considerations or protection may be required to
                address drying of the spring pond. In 2006, 2007, 2008, 2010, and 2016,
                the spring became almost completely dry, and topminnows had to be
                rescued (TNACI 2014, p. 11; Service 2017, p. 20). They were returned to
                the spring on each occasion, after drought subsided. Installation of a
                well with a pump, employed during droughts, would prevent the need to
                rescue topminnows. Assurance of a constant water supply to the spring
                pool during drought would reduce stress on the topminnow population in
                proposed Unit 2, which otherwise will continue to endure frequent
                periods of drought-induced stress due to elevated temperature, lowered
                dissolved oxygen, enhanced depredation, and handling necessary for
                rescue efforts.
                Unit 3: Short Spring
                 Unit 3 is a 1.0-ac (0.4-ha) spring pool in the city of Tullahoma,
                in Coffee County, just west of Short Springs Road and just north of the
                Short Springs Natural Area. The spring pool is formed by a concrete dam
                and feeds a short, approximately 0.1-mile (0.16-km) spring run that
                feeds Bobo Creek. The city owns the unit, and the natural area is
                State-owned. This unit was occupied at the time of listing and is
                currently occupied by the Barrens topminnow. In addition, the unit
                currently supports all breeding, feeding, and sheltering needs for the
                species and contains all of the physical or biological features
                essential to the conservation of the Barrens topminnow.
                 Special management considerations may be required for Unit 3. For
                example, controlling access to the unit for fishing may reduce the
                likelihood of introductions of bait bucket species, including
                mosquitofish, that can compete with or prey upon topminnows.
                Unit 4: Vervilla Spring
                 Unit 4, in Warren County, is a 0.2-mile (0.3-km) reach consisting
                of a series of spring pools and intervening spring run, with its
                downstream end at the Hickory Creek Confluence, just upstream of the
                confluence of Hickory Creek and West Fork Hickory Creek. The unit is
                entirely within a parcel of the Tennessee National Wildlife Refuge,
                owned and managed by the U.S. Fish and Wildlife Service. This unit was
                historically occupied but is currently unoccupied by the Barrens
                topminnow, and it is essential for the conservation of the species.
                Adding a population of Barrens topminnow to this unoccupied unit, after
                raising the level of the dam and removing mosquitofish, would increase
                the species' resiliency and redundancy as is necessary for the
                conservation and recovery of the species, and reduce the species'
                likelihood of extinction. In addition, this unit is habitat for the
                species; it contains all five physical or biological features essential
                to the conservation of the species.
                Unit 5: Marcum Spring
                 Unit 5, in Coffee County, consists of an isolated spring pool and
                0.6 mile (0.9 km) of intervening spring run and natural spring pool
                habitat that terminates in a small pond formed by a constructed
                impoundment. The downstream end of the unit (the impounded pool) is at
                Ovoca Road, where it empties to Ovoca Lake, a small-constructed
                impoundment on Carroll Creek. This unit was occupied at the time of
                listing and is currently occupied by the Barrens topminnow. In
                addition, the unit currently supports all breeding, feeding, and
                sheltering needs for the species and contains all of the physical or
                biological features essential to the conservation of the Barrens
                topminnow. The riparian land adjacent to the unit is privately owned.
                 Special management considerations or protection may be required to
                address sediment washing into the spring from adjacent pasture and to
                address filling portions of the spring for off-road heavy machinery
                access, which has happened before (TNACI 2014, p. 15). In addition,
                maintaining existing fencing at the site would continue to keep
                livestock out of the stream.
                Unit 6: Greenbrook Pond
                 Unit 6 consists of a 0.4-ac (0.16-ha) pond, which is an impounded
                spring pool, and 0.1 mi (0.16 km) of spring run at the pond outflow, in
                Greenbrook Park, in the city of Smithville, Dekalb County. This unit
                was occupied at the time of listing and is currently occupied by the
                Barrens topminnow. In addition, the unit currently supports all
                breeding, feeding, and sheltering needs for the species and contains
                all of the physical or biological features essential to the
                conservation of the Barrens topminnow. The riparian land adjacent to
                the unit is owned by the city of Smithville.
                 Special management considerations may be required for Unit 6.
                Because the unit is in a public park, access to the unit for collecting
                bait fish may need to be controlled, to reduce the likelihood of
                capturing topminnows or of releasing unused bait fish, including
                mosquitofish, that can compete with or prey upon topminnows.
                Unit 7: Big Spring (Merkle)
                 Unit 7, in Franklin County, consists of a springhead and
                approximately 0.5 mi (0.85 km) of spring run. The spring is marked as
                Big Spring on topographic maps but is also referred to by the last name
                of the landowner at the spring head, Merkle. The unit lies on two
                private property parcels and is adjacent to a county road right-of-way.
                [[Page 56260]]
                 The spring flows out of a springhead at the base of a hill and
                through fields used for row-crop agriculture. The stretch upstream of
                Georgia Crossing Road is surrounded by a row-crop field. Below Georgia
                Crossing Road, there is more riparian vegetation, and the stream runs
                adjacent to Hawkins Cove Road. Unit 7 terminates at the confluence with
                Miller Creek.
                 This unit was occupied at the time of listing and is currently
                occupied by the Barrens topminnow. In addition, the unit currently
                supports all breeding, feeding, and sheltering needs for the species
                and contains all of the physical or biological features essential to
                the conservation of the Barrens topminnow. Special management
                considerations may be required for streambank and riparian area
                conservation projects that may occur in Unit 7 in the future. The
                spring run has mostly been channelized and the banks cleared of
                vegetation. Portions of the spring run are occasionally dammed by
                beavers, creating more slackwater habitat and promoting aquatic
                vegetation growth.
                Unit 8: Pepper Hollow Branch
                 Unit 8 consists of 9.2 mi (14.8 km) of Pepper Hollow Branch and its
                permanent tributary reaches upstream of the confluence with the Collins
                River, in Grundy County, Tennessee. The upstream end of the unit starts
                on mainstem Pepper Hollow Branch on the Cumberland Plateau, in a pine
                plantation, from which the stream flows into and through hardwood
                forest until it reaches the valley floor. Areas adjacent to Pepper
                Hollow Branch in the valley are used for nursery production. The
                unnamed tributaries feeding Pepper Hollow Branch are shaded and have a
                mix of riffles and pools with some aquatic vegetation along their
                margins. Tarlton Spring Run, the downstream-most tributary, contains
                abundant aquatic vegetation and flows through open fields in the
                valley. The riparian land adjacent to the unit consists of several
                privately owned parcels.
                 This unit is currently occupied by the Barrens topminnow but had
                not been surveyed and was not known to be occupied at the time of
                listing. This unit is essential for the conservation of the species, as
                this newly discovered population increases the species' resiliency and
                redundancy as is necessary for conservation and recovery of the
                species, and reduces the species' likelihood of extinction. In
                addition, this unit contains all five physical or biological features
                essential to the conservation of the species.
                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.
                 Destruction or adverse modification means a direct or indirect
                alteration that appreciably diminishes the value of critical habitat as
                a whole for the conservation of a listed species (50 CFR 402.02).
                 Compliance with the requirements of section 7(a)(2) of the Act is
                documented 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 formal 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 Service 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 set forth requirements for Federal
                agencies to reinitiate consultation. Reinitiation of consultation is
                required and shall be requested by the Federal agency, where
                discretionary Federal involvement or control over the action has been
                retained or is authorized by law and: (1) If the amount or extent of
                taking specified in the incidental take statement is exceeded; (2) if
                new information reveals effects of the action that may affect listed
                species or critical habitat in a manner or to an extent not previously
                considered; (3) if the identified action is subsequently modified in a
                manner that causes an effect to the listed species or critical habitat
                that was not considered in the biological opinion or written
                concurrence; or (4) if a new species is listed or critical habitat
                designated that may be affected by the identified action. As provided
                in 50 CFR 402.16, the requirement to reinitiate consultations for new
                species listings or critical habitat designation does not apply to
                certain agency actions (e.g., land management plans issued by the
                Bureau of Land Management in certain circumstances).
                Destruction or Adverse Modification of Critical Habitat
                 The key factor related to the destruction or adverse modification
                determination is whether implementation of the proposed Federal action
                directly or indirectly alters the designated critical habitat in a way
                that appreciably diminishes the value of the critical habitat for the
                conservation of the listed species. As discussed above, the role of
                critical habitat is to support physical or biological features
                essential to the conservation of a listed species and provide for the
                conservation of the species.
                 Section 4(b)(8) of the Act requires that our Federal Register
                notices ``shall, to the maximum extent practicable also include a brief
                description and evaluation of those activities (whether public or
                private) which, in the opinion of the Secretary, if undertaken may
                adversely modify [critical] habitat, or may be affected by such
                designation.'' Activities that may be affected by designation of
                critical habitat for the Barrens topminnow include those that may
                affect the physical or biological features of the Barrens topminnow's
                critical habitat (see Physical or Biological Features Essential to the
                Conservation of the Species).

                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 (DoD), or designated for its use, that are subject to an
                integrated natural resources management plan (INRMP) prepared under
                section 101 of the Sikes Act Improvement Act of 1997 (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. No DoD lands with a completed INRMP are within the
                proposed 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 designated critical habitat based on
                economic impacts, impacts on national security, or any other relevant
                impacts. Exclusion decisions are governed by the regulations at 50 CFR
                424.19 and the Policy Regarding Implementation of Section 4(b)(2) of
                the Endangered Species Act (hereafter, the ``2016 Policy''; 81 FR 7226,
                February 11, 2016), both of which were developed jointly with the
                National Marine Fisheries Service (NMFS). We also refer to a 2008
                Department of the Interior Solicitor's opinion entitled, ``The
                Secretary's Authority to Exclude Areas from a Critical Habitat
                Designation under Section 4(b)(2) of the Endangered Species Act'' (M-
                37016).
                 In considering whether to exclude a particular area from the
                designation, we identify the benefits of including the area in the
                designation, identify the benefits of excluding the area from the
                designation, and evaluate whether the benefits of exclusion outweigh
                the benefits of inclusion. If the analysis indicates that the benefits
                of exclusion outweigh the benefits of inclusion, the Secretary may
                exercise discretion to exclude the area only if such exclusion would
                not result in the extinction of the species. In making the
                determination to exclude a particular area, 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. In our final rules, we explain any decision to exclude
                areas, as well as decisions not to exclude, to make clear the rational
                basis for our decision. We describe below the process that we use for
                taking into consideration each category of impacts and any initial
                analyses of the relevant impacts.
                Consideration of Economic Impacts
                 Section 4(b)(2) of the Act and its implementing regulations require
                that we consider the economic impact that may result from a designation
                of critical habitat. To assess the probable economic impacts of a
                designation, we must first evaluate specific land uses or activities
                and projects that may occur in the area of the critical habitat. We
                then must evaluate the impacts that a specific critical habitat
                designation may have on restricting or modifying specific land uses or
                activities for the benefit of the species and its habitat within the
                areas proposed. We then identify which conservation efforts may be the
                result of the species being listed under the Act versus those
                attributed solely to the designation of critical habitat for this
                particular species. The probable economic impact of a proposed critical
                habitat designation is analyzed by comparing scenarios both ``with
                critical habitat'' and ``without critical habitat.''
                 The ``without critical habitat'' scenario represents the baseline
                for the analysis, which includes the existing regulatory and socio-
                economic burden imposed on landowners, managers, or other resource
                users potentially affected by the designation of critical habitat
                (e.g., under the Federal listing as well as other Federal, State, and
                local regulations). Therefore, the baseline represents the costs of all
                efforts attributable to the listing of the species under the Act (i.e.,
                conservation of the species and its habitat incurred regardless of
                whether critical habitat is designated). The ``with critical habitat''
                scenario describes the incremental impacts associated specifically with
                the designation of critical habitat for the species. The incremental
                conservation efforts and associated impacts would not be expected
                without the designation of critical habitat for the species. In other
                words, the incremental costs are those attributable solely to the
                designation of critical habitat, above and beyond the baseline costs.
                These are the costs we use when evaluating the benefits of inclusion
                and exclusion of particular areas from the final designation of
                critical habitat should we choose to conduct a discretionary 4(b)(2)
                exclusion analysis.
                 Executive Order (E.O.) 14094 supplements and reaffirms E.O. 12866
                and E.O. 13563 and directs Federal agencies to assess the costs and
                benefits of available regulatory alternatives in quantitative (to the
                extent feasible) and qualitative terms. Consistent with the E.O.
                regulatory analysis requirements, our effects analysis under the Act
                may take into consideration impacts to both directly and indirectly
                affected entities, where practicable and reasonable. If sufficient data
                are available, we assess to the extent practicable the probable impacts
                to both directly and indirectly affected entities. Section 3(f) of E.O.
                12866 identifies four criteria when a regulation is considered a
                ``significant regulatory action'' and requires additional analysis,
                review, and approval if met. The criterion relevant here is whether the
                designation of critical habitat may have an economic effect of $200
                million or more in any given year (section 3(f)(1) as amended by E.O.
                14094). Therefore, our consideration of economic impacts uses a
                screening analysis to assess whether a designation of critical habitat
                for the Barrens topminnow is likely to exceed the economically
                significant threshold.
                 For this particular designation, we developed an incremental
                effects memorandum (IEM) considering the probable incremental economic
                impacts that may result from this proposed designation of critical
                habitat. The information contained in our IEM was then used to develop
                a screening analysis of the probable effects of the designation of
                critical habitat for the Barrens topminnow (IEC 2023, entire). We began
                by conducting a screening analysis of the proposed designation of
                critical habitat in order to focus our analysis on the key factors that
                are likely to result in incremental economic impacts. The purpose of
                the screening analysis is to filter out particular geographical areas
                of critical habitat that are already subject to such protections and
                are, therefore, unlikely to incur incremental economic impacts. In
                particular, the screening analysis considers baseline costs (i.e.,
                absent critical habitat designation) and includes any probable
                incremental economic impacts where land and water use may already be
                subject to conservation plans, land management plans, best management
                practices, or regulations that protect the habitat area as a result of
                the Federal listing status of the species. Ultimately, the screening
                analysis allows us to focus our analysis on evaluating the specific
                areas or sectors that may incur probable
                [[Page 56262]]
                incremental economic impacts as a result of the designation.
                 The presence of the listed species in occupied areas of critical
                habitat means that any destruction or adverse modification of those
                areas is also likely to jeopardize the continued existence of the
                species. Therefore, designating occupied areas as critical habitat
                typically causes little if any incremental impacts above and beyond the
                impacts of listing the species. As a result, we generally focus the
                screening analysis on areas of unoccupied critical habitat (unoccupied
                units or unoccupied areas within occupied units). Overall, the
                screening analysis assesses whether designation of critical habitat is
                likely to result in any additional management or conservation efforts
                that may incur incremental economic impacts. This screening analysis
                combined with the information contained in our IEM constitute what we
                consider to be our draft economic analysis (DEA) of the proposed
                critical habitat designation for the Barrens topminnow; our DEA is
                summarized in the narrative below.
                 As part of our screening analysis, we considered the types of
                economic activities that are likely to occur within the areas likely
                affected by the critical habitat designation. In our evaluation of the
                probable incremental economic impacts that may result from the proposed
                designation of critical habitat for the Barrens topminnow, first we
                identified, in the IEM dated October 19, 2022, probable incremental
                economic impacts associated with the following categories of
                activities: (1) bridge or highway construction and maintenance; (2)
                development and maintenance of utilities (e.g., pipelines); (3)
                agriculture; (4) water quality permitting; and (5) stream restoration.
                We considered each industry or category individually. Additionally, we
                considered whether their activities have any Federal involvement.
                Critical habitat designation generally will not affect activities that
                do not have any Federal involvement; under the Act, designation of
                critical habitat only affects activities conducted, funded, permitted,
                or authorized by Federal agencies. The species was listed as endangered
                on November 20, 2019 (see 84 FR 56131; October 21, 2019). Therefore, in
                areas where the Barrens topminnow is present, under section 7 of the
                Act, Federal agencies are required to consult with the Service on
                activities they fund, permit, or implement that may affect the species.
                If we finalize this proposed critical habitat designation, our
                consultations would include an evaluation of measures to avoid the
                destruction or adverse modification of critical habitat.
                 In our IEM, we attempted to clarify the distinction between the
                effects that result from the species being listed and those that would
                be attributable to the critical habitat designation (i.e., difference
                between the jeopardy and adverse modification standards) for the
                Barrens topminnow's critical habitat. The following specific
                circumstances help to inform our evaluation: (1) The essential physical
                or biological features identified for critical habitat are the same
                features essential for the life requisites of the species, and (2) any
                actions that would likely adversely affect the essential physical or
                biological features of occupied critical habitat are also likely to
                adversely affect the species itself. The IEM outlines our rationale
                concerning this limited distinction between baseline conservation
                efforts and incremental impacts of the designation of critical habitat
                for this species. This evaluation of the incremental effects has been
                used as the basis to evaluate the probable incremental economic impacts
                of this proposed designation.
                 The proposed critical habitat designation for the Barrens topminnow
                totals approximately 1.5 ac (0.6 ha) of spring pool and 11.4 mi (18.3
                km) of spring run, which includes both occupied and unoccupied habitat.
                Within the currently occupied springs (proposed Units 1, 2, 3, 5, 6, 7,
                and 8), any actions that may affect the species would likely also
                affect proposed critical habitat and it is unlikely that any additional
                conservation efforts would be required to address the adverse
                modification standard over and above those recommended as necessary to
                avoid jeopardizing the continued existence of the species. Thus,
                incremental project modifications resulting solely from the presence of
                occupied critical habitat are not anticipated. In total, approximately
                21 section 7 consultations are anticipated to occur over the next 10
                years in the occupied units, with total costs to the Service and action
                agencies of $75,800, or approximately $7,600 per year.
                 Within the unoccupied Vervilla Spring (proposed Unit 4), any future
                projects that may affect the Barrens topminnow or its critical habitat
                would result in section 7 consultation because the spring is on
                federally managed land. It is not clear that substantial project
                modifications to proposed Unit 4 would be required to accommodate
                critical habitat over and above what would already be anticipated to
                occur under the baseline. With or without critical habitat, this area
                will be managed for Barrens topminnow conservation because the Service
                plans to reintroduce Barrens topminnow into this area. In other words,
                raising the height of the mosquitofish exclusion barrier and
                rehabilitating the unoccupied unit would have been completed to promote
                species recovery by improving the habitat prior to occupation by the
                Barrens topminnow regardless of a critical habitat designation.
                Nevertheless, the screening analysis assumed that raising the height of
                the mosquitofish barrier and rehabilitating unoccupied proposed Unit 4
                is an incremental cost due to the designation of critical habitat. The
                Service estimates the one-time cost of barrier replacement at $12,500.
                In addition to barrier replacement, according to the IEM, one new
                formal section 7 consultation considering only adverse modification is
                anticipated to occur in proposed Unit 4 during the next 10 years, at a
                cost of $17,000. One informal consultation, with estimated
                administrative costs of $8,000, is also anticipated for proposed Unit
                4. Therefore, the total incremental cost for proposed Unit 4 is
                estimated at $37,500 during the next 10 years, or approximately $3,800
                per year. The total incremental cost for all eight units is estimated
                at less than $76,000 over the next 10 years, or $7,600 per year. These
                costs would not reach the threshold of ``significant'' under E.O.
                12866.
                 As noted above, in proposed Unit 8, which is occupied but was not
                known to be occupied at the time of listing, any actions that may
                affect the species would likely also affect proposed critical habitat,
                and it is unlikely that any additional conservation efforts would be
                required to address the adverse modification standard over and above
                those recommended as necessary to avoid jeopardizing the continued
                existence of the species.
                 We are soliciting data and comments from the public on the DEA
                discussed above. During the development of a final designation, we will
                consider the information presented in the DEA and any additional
                information on economic impacts we receive during the public comment
                period to determine whether any specific areas should be excluded from
                the final critical habitat designation under authority of section
                4(b)(2) of the Act, our implementing regulations at 50 CFR 424.19, and
                the 2016 Policy. We may exclude an area from critical habitat if we
                determine that the benefits of excluding the area outweigh the benefits
                of including the area, provided the exclusion will not result in the
                extinction of this species.
                [[Page 56263]]
                Consideration of National Security Impacts
                 Section 4(a)(3)(B)(i) of the Act may not cover all DoD lands or
                areas that pose potential national-security concerns (e.g., a DoD
                installation that is in the process of revising its INRMP for a newly
                listed species or a species previously not covered). If a particular
                area is not covered under section 4(a)(3)(B)(i), then national-security
                or homeland-security concerns are not a factor in the process of
                determining what areas meet the definition of ``critical habitat.''
                However, we must still consider impacts on national security, including
                homeland security, on those lands or areas not covered by section
                4(a)(3)(B)(i) because section 4(b)(2) requires us to consider those
                impacts whenever it designates critical habitat. Accordingly, if DoD,
                Department of Homeland Security (DHS), or another Federal agency has
                requested exclusion based on an assertion of national-security or
                homeland-security concerns, or we have otherwise identified national-
                security or homeland-security impacts from designating particular areas
                as critical habitat, we generally have reason to consider excluding
                those areas.
                 However, we cannot automatically exclude requested areas. When DoD,
                DHS, or another Federal agency requests exclusion from critical habitat
                on the basis of national-security or homeland-security impacts, we must
                conduct an exclusion analysis if the Federal requester provides
                information, including a reasonably specific justification of an
                incremental impact on national security that would result from the
                designation of that specific area as critical habitat. That
                justification could include demonstration of probable impacts, such as
                impacts to ongoing border-security patrols and surveillance activities,
                or a delay in training or facility construction, as a result of
                compliance with section 7(a)(2) of the Act. If the agency requesting
                the exclusion does not provide us with a reasonably specific
                justification, we will contact the agency to recommend that it provide
                a specific justification or clarification of its concerns relative to
                the probable incremental impact that could result from the designation.
                If we conduct an exclusion analysis because the agency provides a
                reasonably specific justification or because we decide to exercise the
                discretion to conduct an exclusion analysis, we will defer to the
                expert judgment of DoD, DHS, or another Federal agency as to: (1)
                Whether activities on its lands or waters, or its activities on other
                lands or waters, have national-security or homeland-security
                implications; (2) the importance of those implications; and (3) the
                degree to which the cited implications would be adversely affected in
                the absence of an exclusion. In that circumstance, in conducting a
                discretionary section 4(b)(2) exclusion analysis, we will give great
                weight to national-security and homeland-security concerns in analyzing
                the benefits of exclusion.
                 In preparing this proposal, we have determined that the lands
                within the proposed designation of critical habitat for the Barrens
                topminnow are not owned or managed by the DoD or DHS, and, therefore,
                we anticipate no impact on national security or homeland security.
                Consideration of Other Relevant Impacts
                 Under section 4(b)(2) of the Act, we consider any other relevant
                impacts, in addition to economic impacts and impacts on national
                security discussed above. To identify other relevant impacts that may
                affect the exclusion analysis, we consider a number of factors,
                including whether there are permitted conservation plans covering the
                species in the area--such as safe harbor agreements (SHAs), candidate
                conservation agreements with assurances (CCAAs) or ``conservation
                benefit agreement'' or ``conservation agreement'' (CBAs) (CBAs are a
                new type of agreement replacing SHAs and CCAAs in use after April 2024
                (89 FR 26070; April 12, 2024)) or HCPs, or whether there are non-
                permitted conservation agreements and partnerships that may be impaired
                by designation of, or exclusion from, critical habitat. In addition, we
                look at whether Tribal conservation plans or partnerships, Tribal
                resources, or government-to-government relationships of the United
                States with Tribal entities may be affected by the designation. We also
                consider any State, local, social, or other impacts that might occur
                because of the designation.
                 In preparing this proposal, we have determined that no HCPs or
                other management plans for the Barrens topminnow currently exist, and
                the proposed designation does not include any Tribal lands or trust
                resources or any lands for which designation would have any economic or
                national-security impacts. Therefore, we anticipate no impact on Tribal
                lands, partnerships, or HCPs from this proposed critical habitat
                designation, and thus, as described above, we are not considering
                excluding any particular areas on the basis of the presence of
                established conservation agreements or impacts to trust resources.
                 When analyzing other relevant impacts of including a particular
                area in a designation of critical habitat, we weigh those impacts
                relative to the conservation value of the particular area. To determine
                the conservation value of designating a particular area, we consider a
                number of factors, including, but not limited to, the additional
                regulatory benefits that the area would receive due to the protection
                from destruction or adverse modification as a result of actions with a
                Federal nexus, the educational benefits of mapping essential habitat
                for recovery of the listed species, and any benefits that may result
                from a designation due to State or Federal laws that may apply to
                critical habitat.
                 After identifying the benefits of inclusion and the benefits of
                exclusion, we carefully weigh the two sides to evaluate whether the
                benefits of exclusion outweigh those of inclusion. If our analysis
                indicates that the benefits of exclusion outweigh the benefits of
                inclusion, we then determine whether exclusion would result in
                extinction of the species. If exclusion of an area from critical
                habitat will result in extinction, we will not exclude it from the
                designation.
                 The Service's Partners for Fish and Wildlife (PFW) program is
                developing conservation agreements with landowners at Benedict Spring
                and Greenbrook Pond, proposed Units 2 and 6, respectively. At Benedict
                Spring, a well would be developed and a pump installed to maintain a
                water supply that would keep the spring full during periods of drought
                to conserve the Barrens topminnow. Lands adjacent to the spring pool
                and spring run constituting the proposed Greenbrook Pond Unit would
                continue to be managed as a city park, under which the population of
                topminnows has persisted in high numbers. Therefore, as indicated in
                Information Requested, we are requesting information on whether the
                benefits of excluding any areas where PFW conservation agreements are
                developed may outweigh inclusion under section 4(b)(2) of the Act, and
                the Secretary may exclude these areas from the final designation of
                critical habitat for the Barrens topminnow.
                 If through the public comment period we receive information that we
                determine indicates that there are potential economic, national
                security, or other relevant impacts from designating particular areas
                as critical habitat, then as part of developing the final designation
                of critical habitat, we will evaluate that information and may
                [[Page 56264]]
                conduct a discretionary exclusion analysis to determine whether to
                exclude those areas under authority of section 4(b)(2) of the Act and
                our implementing regulations at 50 CFR 424.19. If we receive a request
                for exclusion of a particular area and after evaluation of supporting
                information we do not exclude, we will fully describe our decision in
                the final rule for this action.
                Correction
                 In this proposed rule, we include a correction to the final listing
                rule's citation in the entry for the Barrens topminnow in the List of
                Endangered and Threatened Wildlife (List) at 50 CFR 17.11(h). When the
                final listing rule published (84 FR 56131; October 21, 2019), in the
                ``Listing citations and applicable rules'' column of the List, the
                wrong volume number was included in the citation for the Barrens
                topminnow's listing rule. We reflect the corrected information under
                Proposed Regulation Promulgation, below. As explained at 50 CFR
                17.11(f), the ``Listing citations and applicable rules'' column of the
                List is nonregulatory in nature and is provided for informational and
                navigational purposes only.
                Required Determinations
                Clarity of the Rule
                 We are required by Executive Orders 12866 and 12988 and by the
                Presidential Memorandum of June 1, 1998, to write all rules in plain
                language. This means that each rule we publish must:
                 (1) Be logically organized;
                 (2) Use the active voice to address readers directly;
                 (3) Use clear language rather than jargon;
                 (4) Be divided into short sections and sentences; and
                 (5) Use lists and tables wherever possible.
                 If you feel that we have not met these requirements, send us
                comments by one of the methods listed in ADDRESSES. To better help us
                revise the rule, your comments should be as specific as possible. For
                example, you should tell us the numbers of the sections or paragraphs
                that are unclearly written, which sections or sentences are too long,
                the sections where you feel lists or tables would be useful, etc.
                Regulatory Planning and Review (Executive Orders 12866, 13563, and
                14094)
                 Executive Order 14094 reaffirms the principles of E.O. 12866 and
                E.O. 13563 and states that regulatory analysis should facilitate agency
                efforts to develop regulations that serve the public interest, advance
                statutory objectives, and are consistent with E.O. 12866, E.O. 13563,
                and the Presidential Memorandum of January 20, 2021 (Modernizing
                Regulatory Review). Regulatory analysis, as practicable and
                appropriate, shall recognize distributive impacts and equity, to the
                extent permitted by law. 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 proposed rule in a manner consistent with
                these requirements.
                 E.O. 12866, as reaffirmed by E.O. 13563 and E.O. 14094, provides
                that the Office of Information and Regulatory Affairs (OIRA) in the
                Office of Management and Budget (OMB) will review all significant
                rules. OIRA has determined that this rule is not significant.
                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 whether 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.
                 Under the RFA, as amended, and as understood in light of recent
                court decisions, Federal agencies are required to evaluate the
                potential incremental impacts of rulemaking on those entities directly
                regulated by the rulemaking itself; in other words, the RFA does not
                require agencies 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 out 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 would be directly
                regulated if we adopt the proposed critical habitat designation. The
                RFA does not require evaluation of the potential impacts to entities
                not directly regulated. Moreover, Federal agencies are not small
                entities. Therefore, because no small entities would be directly
                regulated by this rulemaking, the Service certifies that, if made final
                as proposed, this critical habitat designation will not have a
                significant economic impact on a substantial number of small entities.
                 In summary, we have considered whether the proposed designation
                would result in a significant economic impact on a substantial number
                of small entities. For the above reasons and based on currently
                available information, we certify that, if made final as proposed, the
                critical habitat designation will not have a significant economic
                impact on a substantial number of small business entities. Therefore,
                an initial 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 ``to the extent
                permitted by law'' when undertaking actions identified as significant
                energy actions. E.O. 13211 defines a ``significant energy action'' as
                an action that (i) is a significant regulatory action under E.O. 12866
                (or any successor order, including most recently E.O. 14094); and (ii)
                is likely to have a significant adverse effect on the supply,
                distribution, or use of energy. In our economic analysis, we did not
                find that this proposed critical habitat designation would
                significantly affect energy supplies, distribution, or use. Therefore,
                this action is not a significant energy action, and there is no
                requirement to prepare a statement of energy effects for this action.
                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 proposed rule would 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
                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 are not likely to 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 proposed rule would significantly
                or uniquely affect small governments. One of the proposed critical
                habitat units is on federally owned land and five units are on private
                land, and thus these six units are not on property belonging to small
                governments. Two of the eight proposed units are on city property, but
                one is within a city park, while the other is within city boundaries
                and abuts a State natural area. Additionally, all proposed units are
                groundwater-fed pools or streams that are not suitable for development
                of buildings or housing.
                Takings--Executive Order 12630
                 In accordance with E.O. 12630 (Government Actions and Interference
                with Constitutionally Protected Private Property Rights), we have
                analyzed the potential takings implications of designating critical
                habitat for the Barrens topminnow in a takings implications assessment.
                The Act does not authorize the Service to regulate private actions on
                private lands or confiscate private property as a result of critical
                habitat designation. Designation of critical habitat does not affect
                land ownership, or establish any closures, or restrictions on use of or
                access to the designated areas. Furthermore, the designation of
                critical habitat does not affect landowner actions that do not require
                Federal funding or permits, nor does it preclude development of habitat
                conservation programs or issuance of incidental take permits to permit
                actions that do require Federal funding or permits to go forward.
                However, Federal agencies are prohibited from carrying out, funding, or
                authorizing actions that would destroy or adversely modify critical
                habitat. A takings implications assessment has been completed for the
                proposed designation of critical habitat for the Barrens topminnow, and
                it concludes that, if adopted as proposed, this designation of critical
                habitat does not pose significant takings implications for lands within
                or affected by the designation.
                Federalism--Executive Order 13132
                 In accordance with E.O. 13132 (Federalism), this proposed 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 proposed critical habitat designation
                with, the appropriate State resource agency in Tennessee. 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 proposed rule
                does not have substantial direct effects either on the State, or on the
                relationship between the national government and the State, or on the
                distribution of powers and responsibilities among the various levels of
                government. The proposed 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 or 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 they 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.
                [[Page 56266]]
                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 requirements of
                sections 3(a) and 3(b)(2) of the Order. We have proposed designating
                critical habitat in accordance with the provisions of the Act. To
                assist the public in understanding the habitat needs of the species,
                this proposed rule identifies the elements of physical or biological
                features essential to the conservation of the species. The proposed
                areas of designated critical habitat are presented on maps, and the
                proposed 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 information collection requirements, and
                a submission to the Office of Management and Budget (OMB) under the
                Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.) is not
                required. We may not conduct or sponsor and you are 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.)
                 Regulations adopted pursuant to section 4(a) of the Act are exempt
                from the National Environmental Policy Act (NEPA; 42 U.S.C. 4321 et
                seq.) and do not require an environmental analysis under NEPA. We
                published a notice outlining our reasons for this determination in the
                Federal Register on October 25, 1983 (48 FR 49244). This includes
                listing, delisting, and reclassification rules, as well as critical
                habitat designations. In a line of cases starting with Douglas County
                v. Babbitt, 48 F.3d 1495 (9th Cir. 1995), the courts have upheld this
                position.
                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), E.O. 13175 (Consultation and Coordination
                With Indian Tribal Governments), the President's memorandum of November
                30, 2022 (Uniform Standards for Tribal Consultation; 87 FR 74479,
                December 5, 2022), 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 Secretary's 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 discussed earlier in this document, we have determined
                that no Tribal lands would be affected by this proposed critical
                habitat designation.

                 (1) Critical habitat units are depicted for Cannon, Coffee, Dekalb,
                Franklin, Grundy, and Warren Counties, Tennessee, on the maps in this
                entry.
                [[Page 56267]]
                 (2) Within these areas, the physical or biological features
                essential to the conservation of the Barrens topminnow consist of the
                following components:
                 (i) Groundwater-fed, first or second order streams and springs that
                persist annually;
                 (ii) Water temperature ranging from 15 to 25 degrees Celsius
                ([deg]C) (59 to 77 degrees Fahrenheit ([deg]F));
                 (iii) Water during base flow with limited turbidity that is
                sufficiently clear for individuals to see spawning and feeding cues;
                 (iv) Submerged native aquatic plants, such as Cladophora and
                Pithophora species, watercress (Nasturtium officinale), rushes (Juncus
                spp.), pondweed (Potamogeton spp.), and eelgrass (Vallisneria spp.), or
                overhanging terrestrial plants and submerged plant roots, to provide
                cover and surfaces for spawning; and
                 (v) A prey base of microcrustaceans and small aquatic insects such
                as chironomids (midges).
                 (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
                [EFFECTIVE DATE OF FINAL RULE].
                 (4) Data layers defining map units were created using Universal
                Transverse Mercator (UTM) Zone 16N coordinates. The hydrologic data
                used in the maps were extracted from U.S. Geological Survey National
                Hydrography Dataset High Resolution (1:24,000 scale) using Geographic
                Coordinate System North American 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 https://www.regulations.gov under Docket No. FWS-R4-ES-2023-0224 and
                at the field office responsible for this designation. You may obtain
                field office location information by contacting one of the Service
                regional offices, the addresses of which are listed at 50 CFR 2.2.
