                Endangered and Threatened Wildlife and Plants; Designation of
                Critical Habitat for Yellow Lance
                AGENCY: Fish and Wildlife Service, Interior.
                ACTION: Final rule.
                -----------------------------------------------------------------------
                SUMMARY: We, the U.S. Fish and Wildlife Service (Service), designate
                critical habitat for the yellow lance (Elliptio lanceolata) under the
                Endangered Species Act of 1973 (Act), as amended. In total,
                approximately 319 river miles (mi) (514 kilometers (km)) fall within 11
                units of critical habitat in Franklin, Granville, Halifax, Johnston,
                Nash, Vance, Wake, and Warren Counties, North Carolina; Brunswick,
                Craig, Culpeper, Dinwiddie, Fauquier, Louisa, Lunenburg, Madison,
                Nottoway, Orange, and Rappahannock Counties, Virginia; and Howard and
                Montgomery Counties, Maryland. This rule extends the Act's protections
                to the yellow lance's designated critical habitat.
                DATES: This rule is effective May 10, 2021.
                ADDRESSES: This final rule is available on the internet at http://www.regulations.gov. Comments and materials we received, as well as
                some supporting documentation we used in preparing this rule, are
                available for public inspection at http://www.regulations.gov.
                 The coordinates or plot points or both from which the maps are
                generated are included in the administrative record for this critical
                habitat designation and are available at http://www.regulations.gov at

                SUPPLEMENTARY INFORMATION:
                Executive Summary
                 Why we need to publish a rule. Under section 4(a)(3) of the
                Endangered Species Act of 1973 (Act), as amended, if we determine that
                a species is an endangered or threatened species, we must designate
                critical habitat to the maximum extent prudent and determinable. We
                published a final rule to list the yellow lance as a threatened species
                on April 3, 2018 (83 FR 14189). Designations of critical habitat can be
                completed only by issuing a rule.
                 Basis for our action. 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 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.
                The critical habitat we are designating in this rule, consisting of 11
                units comprising approximately 319 miles (514 kilometers) of streams
                and rivers, constitutes our current best assessment of the areas that
                meet the definition of critical habitat for the yellow lance.
                 Economic analysis. In accordance with section 4(b)(2) of the Act,
                we prepared an economic analysis of the impacts of designating critical
                habitat for the yellow lance. We published the announcement of, and
                solicited public comments on, the draft economic analysis (DEA; 85 FR
                6856, February 6, 2020). Because we received no comments or new
                information on the DEA, we adopted the DEA as a final version.
                 Public comments. We considered all comments and information we
                received from the public during the comment period on the proposed
                designation of critical habitat for the yellow lance and the associated
                DEA (85 FR 6856; February 6, 2020).
                Supporting Documents
                 As part of the process of listing the yellow lance, a species
                status assessment (SSA) team prepared an SSA report for the species.
                The SSA team was composed of Service biologists, in consultation with
                other species experts. The SSA report represents a compilation of the
                best scientific and commercial data available concerning the status of
                the species, including the impacts of past, present, and future factors
                (both negative and beneficial) affecting the species. The SSA report
                underwent independent peer review by scientists with expertise in
                mussel biology, habitat management, and stressors (factors negatively
                affecting the species) to the species. Along with other information
                submitted during the process of listing the species, the SSA report is
                the primary source of information for this final designation. The SSA
                report and other materials relating to this rule can be found on the
                Service's Southeast Region website at https://www.fws.gov/southeast/
                and at http://www.regulations.gov under Docket No. FWS-R4-ES-2018-0094.
                Previous Federal Actions
                 On April 20, 2010, we were petitioned to list 404 aquatic species
                in the southeastern United States, including yellow lance. In response
                to the petition, we completed a 90-day finding on September 27, 2011
                (76 FR 59836), in which we announced our finding that the petition
                contained substantial information that listing may be warranted for the
                yellow lance. On April 5, 2017, we published a proposed rule to list
                the yellow lance as a threatened species (82 FR 16559). On April 3,
                2018, we published the final rule to list the species as a threatened
                species (83 FR 14189). On February 6, 2020, we published a proposed
                rule to designate critical habitat for the yellow lance (85 FR 6856).
                Please refer to the April 5, 2017, proposed listing rule for a
                discussion of earlier Federal actions regarding the yellow lance.
                Summary of Comments and Recommendations
                 On February 6, 2020, we published in the Federal Register (85 FR
                6856) a proposed rule to designate critical habitat for the yellow
                lance and to make available the associated DEA; the public comment
                period for that proposed rule was open for 60 days, ending April 6,
                2020. During the open comment period, we received 23 public comments on
                the proposed rule; a majority of the comments supported the
                designation, none opposed the designation, and
                [[Page 18190]]
                some included suggestions on how we could refine or improve the
                designation. All substantive information provided to us during the
                comment period has been incorporated directly into this final rule or
                is addressed below.
                 (1) Comment: Two commenters recommended adding to the critical
                habitat designation. One commenter suggested that whole watersheds be
                considered for designation, indicating that protecting entire
                watersheds would improve genetic diversity and resiliency of yellow
                lance populations. Another commenter recommended including vegetative
                buffers in the designation, citing a study on the functions and
                recommended widths of riparian buffer zones: For erosion and sediment
                control, a width of 30 to 98 feet is recommended, and in the case of
                absorbing biocontaminants, nutrients, and pesticides, the width ranges
                are 30 or more feet, 49 to 164 feet, and 49 to 328 feet, respectively.
                 Our Response: Designation of an entire watershed, which we
                interpret to mean all streams and waterbodies within a watershed, would
                include areas that are not occupied by yellow lance, and areas that are
                not suitable habitat for the yellow lance. The Service has determined
                that unoccupied habitat is not essential for the conservation of the
                species. Further, many areas within a watershed are not suitable
                habitat, and therefore do not contain one or more of the physical or
                biological features essential to yellow lance conservation. In other
                words, these areas do not meet the definition of critical habitat.
                Similarly, while the Service recognizes in the SSA report the important
                contribution of riparian buffers to yellow lance habitat, these land
                areas surrounding streams do not meet the definition of critical
                habitat in that they are not specific areas occupied by the species
                that have one or more of the physical and biological features essential
                to yellow lance conservation. As an obligate aquatic species,
                freshwater mussels such as the yellow lance cannot survive in
                terrestrial riparian areas. Therefore, such areas are not considered in
                the designation of critical habitat.
                 (2) Comment: One commenter recommended that exclusion of human-made
                structures should be construed as narrowly as possible and should not
                allow the exclusion of undeveloped land because that land may share a
                parcel with otherwise-excluded pavement or human structures.
                 Our Response: The exclusion of human-made structures from the
                boundaries of the designated critical habitat was intended to apply
                only to the structures included in the Geographic Information Systems
                (GIS) shapefiles of the critical habitat and not to undeveloped land.
                 (3) Comment: One commenter suggested that the Service include in
                the economic analysis consideration of economic benefits of protecting
                yellow lance habitat, including ecosystem services, the protection of
                clean water, the reduced cost of water treatment for drinking water
                supplies, as well as public health benefits.
                 Our Response: As noted in the DEA, the primary intended benefit of
                critical habitat is to support the conservation of endangered and
                threatened species, such as the yellow lance. In order to quantify and
                monetize direct benefits of the designation, information would be
                needed to determine (1) the incremental change in the probability of
                yellow lance conservation expected to result from the critical habitat
                designation, and (2) the public's willingness to pay for such
                beneficial changes. The conclusion was that additional project
                modifications to avoid adverse modification of critical habitat for the
                yellow lance are not anticipated. Because of the uncertainties
                associated with monetary quantification of these benefits, we were not
                able to estimate the economic benefits of ecosystem services, such as
                clean water via mussel-based biofiltration treatment, or broad benefits
                of ecosystem services that flow from protected areas to human
                populations.
                 (4) Comment: One commenter noted that according to the SSA report,
                the yellow lance is dependent on attaching itself to minnows to
                successfully reach its adult stage. The commenter further noted that
                although it is likely true that the yellow lance is mostly being
                hindered by abiotic factors such as pollution and sedimentation,
                establishing a critical habitat for this mussel species should also
                address conditions necessary for the survival of its host species to
                ensure proper development of the yellow lance. The commenter stated
                that yellow lance's glochidia stage coincides with the spawning period
                of minnows--from late spring to mid-summer--and that minnows are
                obligate hosts for this species and require conservation consideration
                in order to ensure proper development of the yellow lance. The
                commenter then asked how this critical habitat can be tailored to also
                meet the needs of the yellow lance's obligate hosts.
                 Our Response: In this critical habitat designation, we identify the
                physical or biological features essential to yellow lance conservation,
                and, of those, we include two physical or biological factors that
                specifically mention the yellow lance's fish hosts: (1) Adequate flows,
                or a hydrologic flow regime (which includes the severity, frequency,
                duration, and seasonality of discharge over time), necessary to
                maintain benthic habitats where the yellow lance is found and to
                maintain connectivity of streams with the floodplain, allowing the
                exchange of nutrients and sediment for maintenance of the mussel's and
                fish host's habitat, food availability, spawning habitat for native
                fishes, and the ability for newly transformed juveniles to settle and
                become established in their habitats; and (2) the presence and
                abundance of fish hosts necessary for yellow lance recruitment. In
                addition, we identify another physical or biological feature essential
                to yellow lance conservation consisting of certain suitable substrates
                and connected instream habitats ``that support a diversity of
                freshwater mussels and native fish.'' Therefore, this critical habitat
                designation does address, in the context of the physical or biological
                features essential to yellow lance conservation, conditions necessary
                for the yellow lance's fish hosts.
                 (5) Comment: One commenter noted that compliance with the existing
                15 federally enacted best management practices (BMPs) for Clean Water
                Act section 404(f)(1) exemption for established silviculture activities
                like crossing a water of the United States, as well as compliance with
                the North Carolina forestry practice guidelines (FPGs), and with any
                other applicable State-enacted riparian buffer rules, should be deemed
                as concurrent protection of critical habitat under the Act (16 U.S.C.
                1531 et seq.).
                 Our Response: The Federal BMP under consideration states, ``The
                discharge shall not take, or jeopardize the continued existence of, a
                threatened or endangered species as defined under the Endangered
                Species Act, or adversely modify or destroy the critical habitat of
                such species.'' Therefore, this Federal BMP restates existing
                requirements of the Act. The North Carolina FPGs are Statewide,
                ``mandatory narrative rule standards that were developed to assure that
                forestry activities are conducted in a manner that protects water
                quality'' (NCFS 2018, p. 1). The Service recognizes that adherence to
                the FPG performance standards described under title 2 of the North
                Carolina Administrative Code at chapter 60, subchapter C, are
                considered by the North Carolina Forest Service to be compliance with
                the Federal BMP
                [[Page 18191]]
                mentioned above. Thus, compliance with FPGs will also protect critical
                habitat.
                 (6) Comment: One commenter recommended we provide Federal funds to
                support cooperative improvements to forest access infrastructure and
                other conservation management measures within the designated critical
                habitat watersheds. The commenter suggested that robust, recurring
                funding could go towards the following activities: (1) Increase the
                availability of portable, temporary bridgemats for loggers to use on
                stream crossings; (2) enhance cost-sharing of prompt and effective
                reforestation after timber harvests; (3) provide cost-shared assistance
                for landowners to remove/renovate/replace substandard, existing forest
                road stream crossings; (4) develop pre-harvest plans for landowners
                through technical assistance provided by a forester; (5) compensate
                landowners in exchange for installing legal protections of critical
                habitat riparian zones; and (6) provide targeted in-woods research,
                study, and/or monitoring.
                 Our Response: The Service is working with forestry partners to
                consider funding opportunities to advance the ideas suggested by the
                commenter.
                 (7) Comment: One commenter offered information about the
                conservation benefits provided to aquatic species on private, working
                forests and requested that the Service include several references for
                our consideration.
                 Our Response: We made several revisions to include new, relevant
                reference materials in the forestry discussion in the SSA report, where
                appropriate, in response to this comment. However, several of the
                references provided by the commenter were not specific to studies of
                the impacts or benefits of forestry management to freshwater mussels
                and, therefore, were not included in the SSA report.
                 (8) Comment: One commenter noted that silvicultural practices
                implemented with BMPs protect aquatic species and, because they are
                widely implemented, should not be viewed as ``special management''; the
                commenter recommended the Service instead recognize BMPs as routine
                practices. They also note that although there are limited data
                documenting relationships between BMPs and some individual aquatic and
                riparian species, there is a significant body of research confirming
                that BMPs contribute to water quality and riparian forest structure and
                provided many references to this effect.
                 Our Response: BMPs are ``management practices'' that are used to
                protect water quality during timber harvests and other forest
                management activities (National Association of State Foresters 2020,
                unpaginated). Because there are a variety of BMPs that may be
                implemented depending on the project in consideration, and because
                there can be a forestry management or harvest plan that details which
                BMPs will be implemented for that particular project, the use of them
                is considered ``management.'' The Act defines ``critical habitat'' as,
                in part, the specific areas within the geographical area occupied by
                the species which may require special management considerations.
                Forestry best ``management practices'' are considered to be management
                considerations needed for the habitat occupied by the yellow lance.
                Whether they are routine or not, there is a management strategy used
                when implementing BMPs; therefore, they can be considered ``special
                management considerations'' under the Act. The SSA report (Service
                2019, p. 49) and the February 6, 2020, proposed rule (85 FR 6861)
                recognize that BMPs can protect water quality and habitat for aquatic
                species. However, as noted by the commenter, there are some species for
                which there are limited data documenting the relationships with BMPs,
                and even with the 43 references provided in the comment letter, there
                are no data presented that consider temporary or long-term effects of
                sedimentation on long-lived, sedentary freshwater mussel species such
                as the yellow lance.
                 (9) Comment: One commenter encourages the Service to modify the
                proposed rule's language to acknowledge that removing large areas of
                forested wetlands and riparian systems is not part of ongoing forest
                management, nor is it compatible with BMP guidelines. The commenter
                states that in making the above statements, the Service appears to rely
                on older sources of information that do not reflect contemporary forest
                management, or possibly sources describing practices in regions other
                than the eastern United States.
                 Our Response: The section of the proposed rule that the commenter
                refers to is Special Management Considerations or Protections (85 FR
                6856, February 6, 2020, p. 85 FR 6861), which states that the features
                essential to the conservation of the yellow lance may require special
                management considerations or protections to reduce threats including
                ``improper forest management or silviculture activities that remove
                large areas of forested wetlands and riparian systems.'' The comment
                implies that the Service improperly characterized this as one of the
                threats against which the special considerations or protections are
                needed; therefore, in this rule, we have clarified that language. After
                reviewing studies within the range of yellow lance in Virginia noted by
                the commenter (Lakel et al. 2010, p. 541) and frequently asked
                questions on the North Carolina State Forest Service's website (NCFS
                2020, unpaginated), the Service notes that clearcutting, or entirely
                removing all trees in a forested area (U.S. Forest Service 2020,
                unpaginated), is a preferred method of harvesting timber. To harvest
                sites, they are often clearcut, burned, and then replanted (Lakel et
                al. 2010, p. 541). The threat to yellow lance from this harvest
                practice is sedimentation from clearcuts near streams. Many of the
                watersheds occupied by yellow lance do not have mandatory buffer
                requirements to eliminate sedimentation, and, as noted above, there are
                no data for the temporary or long-term effects of residual
                sedimentation post-BMP implementation on freshwater mussels. As stated
                above, in response to this comment, we have revised relevant language
                in this rule to clarify that the threat is due to ``improper forest
                management or clearcuts within riparian areas.''
                Summary of Changes From the Proposed Rule
                 This final rule incorporates one minor substantive change to our
                proposed rule (85 FR 6856; February 6, 2020) based on the comments we
                received and that are summarized above under Summary of Comments and
                Recommendations. We revised the language under Special Management
                Considerations or Protections to clarify that the features essential to
                the conservation of the yellow lance may require special management
                considerations or protections to reduce ``improper forest management or
                clearcuts within riparian areas.'' We made no other substantive changes
                from the proposed rule to this final rule.
                Background
                 Critical habitat is defined in section 3 of the Act as:
                 (1) The specific areas within the geographical area occupied by the
                species, at the time it is listed in accordance with the Act, on which
                are found those physical or biological features;
                 (a) Essential to the conservation of the species, and
                 (b) Which may require special management considerations or
                protection; and
                [[Page 18192]]
                 (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. Where a landowner requests Federal agency
                funding or authorization for an action that may affect a listed species
                or critical habitat, the Federal agency would be required to consult
                with the Service under section 7(a)(2) of the Act. However, even if the
                Service were to conclude that the proposed activity would 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 and commercial data available, those physical or biological
                features that are essential to the conservation of the species (such as
                space, food, cover, and protected habitat). In identifying those
                physical or biological features within an area, we focus on the
                specific features that support the life-history needs of the species,
                including, but not limited to, water characteristics, soil type,
                geological features, 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.
                 Under the second prong of the Act's definition of critical habitat,
                we can designate critical habitat in areas outside the geographical
                area occupied by the species at the time it is listed, upon a
                determination that such areas are essential for the conservation of the
                species. When designating critical habitat, the Secretary will first
                evaluate areas occupied by the species. The Secretary will only
                consider unoccupied areas to be essential where a critical habitat
                designation limited to geographical areas occupied by the species would
                be inadequate to ensure the conservation of the species. In addition,
                for an unoccupied area to be considered essential, the Secretary must
                determine that there is a reasonable certainty both that the area will
                contribute to the conservation of the species and that the area
                contains one or more of those physical or biological features essential
                to 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 other 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 this species. Similarly, critical
                habitat designations made on the basis of the best available
                [[Page 18193]]
                information at the time of designation will not control the direction
                and substance of future recovery plans, habitat conservation plans
                (HCPs), or other species conservation planning efforts if new
                information available at the time of these planning efforts calls for a
                different outcome.
                Physical or Biological Features 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 that
                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, alkali 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 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, the Service 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.
                 The yellow lance is a sand-loving species (Alderman 2003, p. 6)
                often found buried deep in clean, coarse to medium sand and sometimes
                migrating with shifting sands (NatureServe 2015, p. 6), although it has
                also been found in gravel substrates. Yellow lance adults require
                clear, flowing water with a temperature less than 35 degrees Celsius
                ([deg]C) (95 degrees Fahrenheit ([deg]F)) and a dissolved oxygen
                greater than 3 milligrams per liter (mg/L). Juveniles require very
                specific interstitial chemistry to complete that life stage: Low
                salinity (similar to 0.9 parts per thousand (ppt)), low ammonia
                (similar to 0.7 mg/L), low levels of copper and other contaminants, and
                dissolved oxygen greater than 1.3 mg/L. Most freshwater mussels,
                including the yellow lance, are found in aggregations (mussel beds)
                that vary in size and are often separated by stream reaches in which
                mussels are absent or rare (Vaughn 2012, p. 983). Genetic exchange
                occurs between and among mussel beds via sperm drift, host fish
                movement, and movement of mussels during high flow events.
                 The yellow lance is an omnivore that primarily filter feeds on a
                wide variety of microscopic particulate matter suspended in the water
                column, including phytoplankton, zooplankton, bacteria, detritus, and
                dissolved organic matter, and these food resources are closely tied to
                riparian area inputs to the stream (Haag 2012, p. 26). Like most
                freshwater mussels, they have a unique life cycle that relies on fish
                hosts for successful reproduction. Yellow lance larvae (glochidia) are
                obligate parasites of the gills, heads, or fins of fish; primary host
                species are members of the Cyprinidae family, including the white
                shiner (Luxilus albeolus) and pinewoods shiner (Lythrurus matutinus).
                 A thorough review of the life history and ecology of yellow lance
                is presented in the SSA report (Service 2019, entire), available on
                http://www.regulations.gov at Docket No. FWS-R4-ES-2018-0094.
                Summary of Essential Physical or Biological Features
                 We derive the specific physical or biological features essential to
                yellow lance conservation from studies of the species' habitat,
                ecology, and life history as described above, and in the SSA report. We
                have determined that the following physical or biological features are
                essential to yellow lance conservation:
                 (1) Suitable substrates and connected instream habitats,
                characterized by geomorphically stable stream channels and banks (i.e.,
                channels that maintain lateral dimensions, longitudinal profiles, and
                sinuosity patterns over time without an aggrading or degrading bed
                elevation) with habitats that support a diversity of freshwater mussels
                and native fish (such as stable riffle-run-pool habitats that provide
                flow refuges consisting of silt-free gravel and coarse sand
                substrates).
                 (2) Adequate flows, or a hydrologic flow regime (which includes the
                severity, frequency, duration, and seasonality of discharge over time),
                necessary to maintain benthic habitats where the species is found and
                to maintain connectivity of streams with the floodplain, allowing the
                exchange of nutrients and sediment for maintenance of the mussel's and
                fish host's habitat, food availability, spawning habitat for native
                fishes, and the ability of newly transformed juveniles to settle and
                become established in their habitats.
                 (3) Water and sediment quality (including, but not limited to,
                conductivity, hardness, turbidity, temperature, pH, ammonia, heavy
                metals, and chemical constituents) necessary to sustain natural
                physiological processes for normal behavior, growth, and viability of
                all life stages.
                 (4) The presence and abundance of fish hosts necessary for yellow
                lance recruitment.
                Special Management Considerations or Protection
                 When designating critical habitat, we assess whether the specific
                areas within the geographical area occupied by the species at the time
                of listing contain features that are essential to the conservation of
                the species and which may require special management considerations or
                protection. Activities on the surrounding landscape and in riparian
                areas are closely tied to instream habitat, therefore special
                management considerations can be linked to activities on land that
                influence the stream and instream habitat. The features essential to
                yellow lance conservation may require special management considerations
                or protections to reduce the following threats: (1) Reduction in water
                quality, quantity, and resulting sedimentation as
                [[Page 18194]]
                a result of urbanization of the landscape, including (but not limited
                to) land conversion for urban and commercial use, infrastructure
                (roads, bridges, utilities), and urban water uses (water supply
                reservoirs, wastewater treatment, etc.); (2) nutrient pollution from
                agricultural activities that impact water quantity and quality; (3)
                significant alteration of water quality; (4) sedimentation from
                incompatible forest management or clearcuts in riparian areas; (5)
                culvert and pipe installations that create barriers to instream
                movement; (6) impacts from invasive species; (7) changes and shifts in
                seasonal precipitation patterns as a result of climate change; and (8)
                other watershed and floodplain disturbances that release sediments or
                nutrients into the water.
                 Management activities that could ameliorate these threats include,
                but are not limited to: Use of BMPs designed to reduce sedimentation,
                erosion, and bank side destruction; protection of riparian corridors
                and retention of sufficient canopy cover along banks; moderation of
                surface and ground water withdrawals to maintain natural flow regimes;
                increased use of stormwater management and reduction of stormwater
                flows into the systems; and reduction of other watershed and floodplain
                disturbances that release sediments, pollutants, or nutrients into the
                water.
                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. As discussed in more detail below,
                we are not designating any areas outside the geographical area occupied
                by the species at the time of listing because we have not identified
                any unoccupied areas that are essential for the conservation of the
                species.
                 The current distribution of the yellow lance is reduced from its
                historical distribution. We anticipate that recovery will require
                continued protection of existing populations and habitat, as well as
                ensuring there are adequate numbers of mussels in stable populations
                and that these populations occur over a wide geographic area. This
                strategy will help to ensure that catastrophic events, such as floods,
                which can cause excessive sedimentation, nutrients, and debris to
                disrupt stream ecology, cannot simultaneously affect all known
                populations. 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 final critical habitat designation.
                 Sources of data for this final critical habitat include multiple
                databases maintained by universities and State agencies for North
                Carolina, Virginia, and Maryland, and numerous survey reports on
                streams throughout the species' range. Other sources of available
                information on habitat requirements for this species include studies
                conducted at occupied sites and published in peer-reviewed articles,
                agency reports, and data collected during monitoring efforts (Service
                2019, entire).
                Areas Occupied at the Time of Listing
                 This critical habitat designation does not include all streams
                known to have been occupied by the species historically; instead, it
                focuses on streams and rivers within the historical range that have
                also retained the necessary physical or biological features that will
                allow for the maintenance and expansion of existing populations and
                that were occupied at the time of listing. First, we identified stream
                channels that currently support yellow lance populations. In the SSA
                report, we define ``currently support'' as stream channels with
                observations of the species from 2005 to present. Due to the breadth
                and intensity of survey effort done for freshwater mussels throughout
                the known range of the species, it is reasonable to assume that streams
                with no positive surveys since 2005 should not be considered occupied
                for the purpose of our analysis.
                 Specific habitat areas were delineated based on Natural Heritage
                Element Occurrences (EOs) following NatureServe's occurrence
                delineation protocol for freshwater mussels (NatureServe 2018,
                unpaginated). These EOs provide habitat for yellow lance subpopulations
                and are large enough to be self-sustaining over time, despite
                fluctuations in local conditions. The EOs contain stream reaches with
                interconnected waters so that host fish containing yellow lance
                glochidia can move between areas, at least during certain flows or
                seasons. Based on this information, we consider the following streams
                in Maryland, Virginia, and North Carolina to have been occupied by the
                species at the time of listing: Patuxent River, Rappahannock Subbasin
                (including the Rappahannock River, South Run, Carter Run, Thumb Run,
                Hungry Run, and Great Run), Rapidan Subbasin (including the Rapidan
                River, Blue Run, and Marsh Run), South Anna River, Johns Creek,
                Nottoway Subbasin (including the Nottoway River, Crooked Creek, and
                Sturgeon Creek), Tar River, Sandy/Swift Creek, Fishing Creek Subbasin
                (including Fishing Creek, Shocco Creek, and Richneck Creek), Swift
                Creek, and Little River.
                Areas Outside the Geographic Area Occupied at the Time of Listing
                 We are not designating any areas outside the geographical area
                occupied by the species at the time of listing because we did not find
                any unoccupied areas that are essential for the conservation of the
                species. The protection of stream segments within the seven currently
                existing populations (Patuxent, Rappahannock, York, James, Chowan, Tar,
                and Neuse), which are located across the physiographic representation
                of the range, would sufficiently reduce the risk of extinction.
                Improving the resiliency of populations in the currently occupied
                streams will increase viability to the point that the protections of
                the Act are no longer necessary.
                Critical Habitat Maps
                 When determining critical habitat boundaries, we made every effort
                to avoid including developed areas such as lands covered by buildings,
                pavement, and other structures because such lands lack physical or
                biological features necessary for yellow lance. 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 rule have been excluded by text in
                the rule and are not included for designation as critical habitat.
                Therefore, a Federal action involving these lands would not trigger
                section 7 consultation under the Act with respect to critical habitat
                and the requirement of no adverse modification unless the specific
                action would affect the physical or biological features in the adjacent
                critical habitat.
                 The critical habitat designation is defined by the maps, as
                modified by any accompanying regulatory text, presented at the end of
                this document under Regulation Promulgation. We include more detailed
                information on the boundaries of the critical habitat designation in
                the discussion of
                [[Page 18195]]
                individual units below. We will make the GIS shapefiles on which each
                map is based available to the public at http://www.regulations.gov
                under Docket No. FWS-R4-ES-2018-0094, at http://www.fws.gov/southeast.
                Final Critical Habitat Designation
                 We are designating approximately 319 river mi (514 km) in 11 units
                in North Carolina, Virginia, and Maryland as critical habitat for the
                yellow lance. All of the units were occupied by the species at the time
                of listing and contain some or all of the physical and biological
                features that are essential to support life-history processes of the
                species. These critical habitat areas, described below, constitute our
                current best assessment of areas that meet the definition of critical
                habitat for yellow lance. The table below shows the name, land
                ownership of the riparian areas surrounding the units, and approximate
                river miles of the designated units for yellow lance. Because all
                streambeds are navigable waters, the actual critical habitat units are
                all owned by the State where they occur. The riparian land adjacent to
                the critical habitat is 83 percent private lands, 11 percent
                conservation lands and easements, and 6 percent State lands.

                 We present brief descriptions of all units, and reasons why they
                meet the definition of critical habitat for yellow lance, below.
                Patuxent Population
                Unit 1: PR1--Patuxent River
                 Unit 1 consists of approximately 10 river mi (16.1 km), including 3
                mi (4.8 km) of the Patuxent River and 7 mi (11.3 km) of the Hawlings
                River, in Montgomery and Howard Counties, Maryland. The riparian land
                adjacent to Patuxent River is primarily located in Patuxent River State
                Park (90 percent), with some parcels privately owned (10 percent); the
                riparian land surrounding the Hawlings River is predominantly
                conservation parcels (97 percent) including State, county, and Maryland
                National Capital Parks Planning (MD NCPP) park land, and some privately
                owned parcels (3 percent).
                 Special management considerations or protection may be required to
                address excess nutrients, sediment, and pollutants that enter the
                rivers and serve as indicators of other forms of pollution such as
                bacteria and toxins, all of which reduce water quality for the species.
                Primary sources of these types of pollution result from urbanization
                and include wastewater, stormwater runoff, and fertilizers. Portions of
                the upper Patuxent River watershed were listed in 2011 as impaired for
                aquatic life and wildlife due to total suspended solids, and in 2014
                due to chlorides and sulfates (MDE 2016, unpaginated). There are 146
                non-major National Pollutant Discharge Elimination System (NPDES)
                discharges and three major (including Maryland City Water Reclamation
                Facility (WRF) and Bowie Wastewater Treatment Plant (WWTP)) NPDES
                discharges in the management unit. The Patuxent River is also
                fragmented by two water supply reservoirs, one with dual use as a
                hydroelectric facility. Given the urban stormwater and nonpoint source
                pollution identified as contributing to water quality issues in this
                unit, special management considerations related to developed areas
                including riparian buffer restoration, reduced surface and groundwater
                withdrawals, stormwater retrofits, eliminating direct stormwater
                discharges, increasing open space in the watershed, and implementing
                highest levels of wastewater treatment practicable will benefit the
                species' habitat in this unit.
                Rappahannock Population
                Unit 2: RR1--Rappahannock Subbasin
                 Unit 2 consists of approximately 44 river mi (70.8 km) of
                Rappahannock Subbasin, including 1.7 mi (2.7 km) in Hungry Run, 7.9 mi
                (12.7 km) in Thumb Run, 5.9 mi (9.5 km) in South Run/Carter Run, 2.7 mi
                (4.3 km) in Great Run, and 25.8 mi (41.6 km) in Rappahannock River in
                Rappahannock, Fauquier, and Culpeper Counties, Virginia. The riparian
                land adjacent to this unit is primarily privately owned (72 percent),
                with some conservation parcels (28 percent).
                 Special management considerations or protection may be required to
                address excess nutrients, sediment, and pollutants that enter the river
                and serve as indicators of other forms of pollution such as bacteria
                and toxins, all of which impact water quality for the species. Sources
                of these types of pollution include wastewater, agricultural runoff,
                stormwater runoff, and septic systems. Approximately 77 miles (123.9
                km) of the Rappahannock River watershed are impaired for aquatic life.
                Impairment is indicated by low benthic-macroinvertebrate bioassessment
                scores, pH and temperature issues, and Escherichia coli (E. coli);
                several of these can be attributed to septic systems or nonpoint source
                runoff into streams. There are 93 non-major NPDES discharges and 11
                major NPDES discharges, including several city and package WWTPs,
                within this unit. Special management considerations for riparian buffer
                restoration, agricultural BMPs, stormwater retrofits, maintenance of
                forested buffers, and implementing highest levels of wastewater
                treatment practicable will benefit the habitat for the species in this
                unit.
                [[Page 18196]]
                Unit 3: RR2--Rapidan Subbasin
                 Unit 3 consists of approximately 9 river mi (14.5 km) of Rapidan
                Subbasin, including 1.2 mi (1.9 km) in Marsh Run, 3.1 mi (5.0 km) in
                Blue Run, and 4.7 mi (7.6 km) in the Rapidan River in Madison and
                Orange Counties, Virginia. The riparian land adjacent to this unit is
                privately owned (57 percent) and conservation parcels (43 percent).
                 Special management considerations or protection may be required to
                address excess nutrients, sediment, and pollutants that enter the river
                and serve as indicators of other forms of pollution such as bacteria
                and toxins, all of which reduce water quality for the species (see
                discussion for Unit 2, above). Special management considerations for
                riparian buffer restoration, agricultural BMPs, stormwater retrofits,
                maintenance of forested buffers, and implementing highest levels of
                wastewater treatment practicable will benefit the habitat for the
                species in this unit.
                York Population
                Unit 4: YR1--South Anna River
                 Unit 4 consists of approximately 8 river mi (12.9 km) of the South
                Anna River in Louisa County, Virginia. The riparian land adjacent to
                this unit is primarily privately owned (92 percent), with some
                conservation parcels (8 percent).
                 Special management considerations or protection may be required to
                address excess nutrients, sediment, and pollutants that enter the river
                and serve as indicators of other forms of pollution such as bacteria
                and toxins, all of which impact water quality for the species. Sources
                of these types of pollution include wastewater, agricultural runoff,
                stormwater runoff, and septic systems. Based on 2012 data, 13 stream
                reaches, totaling approximately 44 miles (70.8 km), are impaired for
                aquatic life in the Po River and South Anna River watersheds.
                Impairment is indicated by low benthic-macroinvertebrate bioassessment
                scores, low dissolved oxygen, pH, and E. coli. There are 50 non-major
                NPDES discharges in the basin, and one major discharge, the Ashland
                WWTP. Special management considerations for riparian buffer
                restoration, agricultural BMPs, stormwater retrofits, maintenance of
                forested buffers, and implementing highest levels of wastewater
                treatment practicable will benefit the habitat for the species in this
                unit.
                James Population
                Unit 5: JR1--Johns Creek
                 Unit 5 consists of approximately 14 river mi (22.5 km) of the Johns
                Creek in Craig County, Virginia. The riparian land adjacent to this
                unit is primarily private, with some federally owned land as part of
                George Washington and Jefferson National Forest.
                 Special management considerations or protection may be required to
                address excess nutrients, sediment, and pollutants, which enter the
                creek and serve as indicators of other forms of pollution such as
                bacteria and toxins, all of which impact water quality for the species.
                Sources of these types of pollution are wastewater, agricultural
                runoff, and urban stormwater runoff. National Forest lands surround
                most of the Johns Creek watershed; protections and management of these
                lands will likely enable habitat conditions (water quality, water
                quantity/flow, instream substrate, and connectivity) to remain high
                into the future (Service 2019, entire). Targeted species restoration in
                conjunction with current associated-species restoration efforts in
                Johns, Dicks, and Little Oregon Creeks within the Craig Creek Subbasin
                will likely improve the yellow lance's resiliency in these areas.
                Maintenance of forested buffer conditions is essential to retaining
                high-quality instream habitat in this unit.
                Chowan Population
                Unit 6: CR1--Nottoway Subbasin
                 Unit 6 consists of approximately 41 river mi (66 km) of Nottoway
                Subbasin, including 1.4 mi (2.3 km) in Crooked Creek, 3.3 mi (5.3 km)
                in Sturgeon Creek, and 36.3 mi (58.4 km) in the Nottoway River in
                Nottoway, Lunenburg, Brunswick, and Dinwiddie Counties, Virginia. The
                designation begins upstream of VA49 and ends at its confluence with
                Sturgeon Creek. The riparian land adjacent to this unit is primarily
                privately owned (64 percent), although Fort Pickett Military
                Reservation, which is exempted from this critical habitat designation,
                also has frontage on the Nottoway River (33 percent; see Exemptions,
                below), and there are some conservation parcels (3 percent).
                 Special management considerations or protection may be required
                within this unit to address a variety of threats. In the past decade,
                the Nottoway River suffered from several seasonal drought events, which
                not only caused low dissolved oxygen conditions but also decreased food
                delivery because of minimal flows. In addition, these conditions led to
                increased predation rates on potential host fishes that were
                concentrated into low-flow refugia (e.g., pools). Urban stormwater and
                nonpoint source pollution have been identified as contributing to water
                quality issues in this unit. Additional threats to this unit include
                oil and gas pipeline projects that propose to cross streams at
                locations where the species occurs, with special management
                recommendations of alternate routes for oil and gas pipelines, or
                directional boring for those projects. Special management
                considerations for riparian buffer restoration, reduced surface and
                groundwater withdrawals, and stormwater retrofits will benefit the
                habitat in this unit. Additional special management considerations or
                protection may be required within this unit to address low water levels
                as a result of water withdrawals and drought.
                Tar Population
                Unit 7: TR1--Tar River
                 Unit 7 consists of approximately 91 river mi (146.5 km) of the Tar
                River, including 4.4 mi (7.1 km) in Ruin Creek, 11.9 mi (19.2 km) in
                Tabbs Creek, 6.8 mi (10.9 km) in Crooked Creek, and 67.9 mi (109.3 km)
                in the Tar River in Granville, Vance, Franklin, and Nash Counties,
                North Carolina. The riparian land adjacent to this unit is almost all
                privately owned (98 percent), with a few conservation parcels (2
                percent).
                 Special management considerations or protection may be required
                within this unit to address a variety of threats. Excessive amounts of
                nitrogen and phosphorus run off the land, or are discharged, into the
                waters, causing excessive growth of vegetation and leading to extremely
                low levels of dissolved oxygen. Based on 2014 data, seven stream
                reaches totaling approximately 38 miles (61.1 km) are impaired in this
                basin. Indicators of impairment are low dissolved oxygen and low
                benthic-macroinvertebrate assessment scores, and the entire basin is
                classified as Nutrient Sensitive Waters (NCDEQ 2016, pp. 115-117).
                There are 102 non-major NPDES discharges, including several package
                WWTPs and biosolids facilities, and 3 major NPDES discharges (Oxford
                WWTP, Louisburg WWTP, and Franklin County WWTP) in this unit; with
                expansion of these facilities, or addition of new wastewater
                discharges, an additional threat to habitat exists in this unit.
                Special management focused on agricultural BMPs, implementing highest
                levels of wastewater treatment practicable, maintenance of forested
                buffers, and connection of protected riparian corridors will benefit
                habitat for the species in this unit.
                [[Page 18197]]
                Unit 8: TR2--Sandy/Swift Creek
                 Unit 8 consists of approximately 31 river mi (50 km) of Sandy/Swift
                Creek in Vance, Warren, Halifax, Franklin, and Nash Counties, North
                Carolina. The riparian land adjacent to this unit is primarily
                privately owned (92 percent), with the rest in either conservation
                easements (2.5 percent) or State Game Land parcels (4.6 percent).
                 Special management considerations or protection may be required
                within this unit to address a variety of threats. Excessive amounts of
                nitrogen and phosphorus run off the land, or are discharged, into the
                waters, causing excessive growth of vegetation and leading to extremely
                low levels of dissolved oxygen; one stream reach totaling approximately
                5 miles (8 km) is impaired in this unit. Special management focused on
                agricultural BMPs, maintenance of forested buffers, and connection of
                protected riparian corridors will benefit habitat for the species in
                this unit.
                Unit 9: TR3--Fishing Creek Subbasin
                 Unit 9 consists of approximately 37 river mi (59.5 km) of Fishing
                Creek Subbasin, including 1.6 mi (2.6 km) in Richneck Creek, 8.0 mi
                (12.9 km) in Shocco Creek, and 27.4 mi (44 km) in Fishing Creek in
                Vance, Warren, Halifax, Franklin, and Nash Counties, North Carolina.
                The riparian land adjacent to this unit is primarily in private
                ownership (85 percent), with some State Game Land parcels (12 percent)
                and conservation easements (3 percent).
                 Special management considerations or protection may be required
                within this unit to address a variety of threats. Excessive amounts of
                nitrogen and phosphorus run off the land, or are discharged, into the
                waters, causing excessive growth of vegetation and leading to extremely
                low levels of dissolved oxygen. Special management focused on
                agricultural BMPs, maintenance of forested buffers, and connection of
                protected riparian corridors will benefit habitat for the species in
                this unit.
                Neuse Population
                Unit 10: NR1--Swift Creek
                 Unit 10 consists of approximately 24 river mi (38.6 km) of the
                Swift Creek in Wake and Johnston Counties, North Carolina. The riparian
                land adjacent to this unit is almost entirely privately owned (99.5
                percent), with one conservation parcel (0.5 percent).
                 Special management considerations or protection may be required
                within this unit to address a variety of threats. Large quantities of
                nutrients (especially nitrogen) contributed by fertilizers and animal
                waste washed from lawns, urban developed areas, and farm fields are
                impacting aquatic ecosystems in this unit. There are several permitted
                point source discharges of wastewater. Development is also impacting
                several areas along Swift Creek.
                 All of Swift Creek is rated ``impaired'' by the North Carolina
                Division of Water Resources. Many factors contribute to this
                designation, including low benthic-macroinvertebrate assessment scores,
                low pH, poor fish community scores, low dissolved oxygen,
                polychlorinated biphenyls, copper, and zinc. Many non-major and one
                major (Dempsey Benton Water Treatment Plant) permitted discharges occur
                in this unit. Special management related to developed areas, including
                using the best available wastewater treatment technologies,
                retrofitting stormwater systems, eliminating direct stormwater
                discharges, increasing open space in the watershed, and maintaining
                connected riparian corridors, will be important to maintain habitat in
                this unit.
                Unit 11: NR2--Little River
                 Unit 11 consists of approximately 10 river mi (16.1 km) of the
                Little River in Johnston County, North Carolina. The riparian land
                adjacent to this unit is almost entirely privately owned (99.5
                percent), with one conservation parcel (0.5 percent).
                 Special management considerations or protection may be required
                within this unit to address a variety of threats. Four stream reaches
                totaling approximately 17 miles are impaired in the Little River. The
                designation of impairment is based primarily on low benthic-
                macroinvertebrate assessment scores, low pH, and low dissolved oxygen.
                There are 32 non-major and no major NPDES discharges in this unit.
                Special management considerations in this unit include retrofitting
                stormwater systems, eliminating direct stormwater discharges,
                increasing and protecting existing open space, and maintaining
                connected riparian corridors.
                Effects of Critical Habitat Designation
                Section 7 Consultation
                 Section 7(a) of the Act requires Federal agencies to evaluate their
                actions with respect to any species that is proposed or listed as an
                endangered or threatened species and with respect to its critical
                habitat, if any is designated. 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 listed
                under the Act or result in the destruction or adverse modification of
                critical habitat.
                 We published a final regulation with a revised definition of
                destruction or adverse modification on August 27, 2019 (84 FR 44976).
                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.
                 If a Federal action may affect a listed species or its critical
                habitat, the responsible Federal agency (action agency) must enter into
                consultation with us. Examples of actions that are subject to the
                section 7 consultation process are actions on State, Tribal, local, or
                private lands that require a Federal permit (such as a permit from the
                U.S. Army Corps of Engineers under section 404 of the Clean Water Act
                (33 U.S.C. 1251 et seq.) or a permit from the Service under section 10
                of the Act) or that involve some other Federal action (such as funding
                from the Federal Highway Administration, Federal Aviation
                Administration, or the Federal Emergency Management Agency). Federal
                agency actions within the species' habitat that may require conference
                or consultation or both include management and any other landscape-
                altering activities on Federal lands administered by the Service, Army
                National Guard, U.S. Forest Service, and National Park Service;
                issuance of section 404 Clean Water Act permits by the U.S. Army Corps
                of Engineers; and construction and maintenance of roads or highways by
                the Federal Highway Administration. Federal actions not affecting
                listed species or critical habitat, and actions on State, Tribal,
                local, or private lands that are not federally funded, authorized, or
                carried out by a Federal agency, do not require section 7 consultation.
                 Compliance with the requirements of section 7(a)(2), 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
                [[Page 18198]]
                adversely affect, listed species or critical habitat.
                 When we issue a biological opinion concluding that a project is
                likely to jeopardize the continued existence of a listed species and/or
                destroy or adversely modify critical habitat, we provide reasonable and
                prudent alternatives to the project, if any are identifiable, that
                would avoid the likelihood of jeopardy and/or destruction or adverse
                modification of critical habitat. We define ``reasonable and prudent
                alternatives'' (at 50 CFR 402.02) as alternative actions identified
                during consultation that:
                 (1) Can be implemented in a manner consistent with the intended
                purpose of the action,
                 (2) Can be implemented consistent with the scope of the Federal
                agency's legal authority and jurisdiction,
                 (3) Are economically and technologically feasible, and
                 (4) Would 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 formal consultation on previously reviewed
                actions. These requirements apply when the Federal agency has retained
                discretionary involvement or control over the action (or the agency's
                discretionary involvement or control is authorized by law) and,
                subsequent to the previous consultation, we have listed a new species
                or designated critical habitat that may be affected by the Federal
                action, or the action has been modified in a manner that affects the
                species or critical habitat in a way not considered in the previous
                consultation. In such situations, Federal agencies sometimes may need
                to request reinitiation of consultation with us, but the regulations
                also specify some exceptions to the requirement to reinitiate
                consultation on specific land management plans after subsequently
                listing a new species or designating new critical habitat. See the
                regulations for a description of those exceptions.
                Application of the ``Destruction or Adverse Modification'' Standard
                 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 as a
                whole 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 us to briefly evaluate and
                describe, in any proposed or final regulation that designates critical
                habitat, activities involving a Federal action that may violate 7(a)(2)
                of the Act by destroying or adversely modifying such designation, or
                that may be affected by such designation.
                 Activities that the Services may, during a consultation under
                section 7(a)(2) of the Act, find are likely to destroy or adversely
                modify critical habitat include, but are not limited to:
                 (1) Actions that would alter the minimum flow or the existing flow
                regime. Such activities could include, but are not limited to,
                impoundment, channelization, water diversion, water withdrawal, and
                hydropower generation. These activities could eliminate or reduce the
                habitat necessary for the growth and reproduction of yellow lance and/
                or its fish host by decreasing or altering flows to levels that would
                adversely affect their ability to complete their life cycles.
                 (2) Actions that would significantly alter water chemistry or
                temperature. Such activities could include, but are not limited to,
                release of chemicals (including pharmaceuticals, metals, and salts),
                biological pollutants, or heated effluents into the surface water or
                connected groundwater at a point source or by dispersed release (non-
                point source). These activities could alter water conditions to levels
                that are beyond the tolerances of yellow lance and/or its fish host and
                result in direct or cumulative adverse effects to these individuals and
                their life cycles.
                 (3) Actions that would significantly increase sediment deposition
                within the stream channel. Such activities could include, but are not
                limited to, excessive sedimentation from livestock grazing, road
                construction, channel alteration, timber harvest, off-road vehicle use,
                and other watershed and floodplain disturbances. These activities could
                eliminate or reduce the habitat necessary for the growth and
                reproduction of yellow lance and/or its fish host by increasing the
                sediment deposition to levels that would adversely affect their ability
                to complete their life cycles.
                 (4) Actions that would significantly increase the filamentous algal
                community within the stream channel. Such activities could include, but
                are not limited to, release of nutrients into the surface water or
                connected groundwater at a point source or by dispersed release (non-
                point source). These activities can result in excessive filamentous
                algae filling streams and reducing habitat for the yellow lance and/or
                its fish host, degrading water quality during algal decay, and
                decreasing oxygen levels at night from algal respiration to levels
                below the tolerances of the mussel and/or its fish host. Algae can also
                directly compete with mussel offspring by covering the sediment, which
                prevents the glochidia from settling into the sediment.
                 (5) Actions that would significantly alter channel morphology or
                geometry. Such activities could include, but are not limited to,
                channelization, impoundment, road and bridge construction, mining,
                dredging, oil and gas pipeline crossings, and destruction of riparian
                vegetation. These activities may lead to changes in water flows and
                levels that would degrade or eliminate the mussel, its fish host, and/
                or their habitats. These actions can also lead to increased
                sedimentation and degradation in water quality to levels that are
                beyond the tolerances of yellow lance and/or its fish host.
                 (6) Actions that result in the introduction, spread, or
                augmentation of nonnative aquatic species in occupied stream segments,
                or in stream segments that are hydrologically connected to occupied
                stream segments, even if those segments are occasionally intermittent,
                or introduction of other species that compete with or prey on the
                yellow lance. Possible actions could include, but are not limited to,
                stocking of nonnative fishes, stocking of sport fish, or other related
                actions. These activities can introduce parasites or disease to fish
                hosts; result in direct predation; or affect the growth, reproduction,
                and survival of yellow lance.
                Exemptions
                Application of Section 4(a)(3) of the Act
                 The Sikes Act Improvement Act of 1997 (Sikes Act) (16 U.S.C. 670a)
                required each military installation that includes land and water
                suitable for the conservation and management of natural resources to
                complete an integrated natural resources management plan (INRMP) by
                November 17, 2001. An INRMP integrates implementation of the
                [[Page 18199]]
                military mission of the installation with stewardship of the natural
                resources found on the base. Each INRMP includes:
                 (1) An assessment of the ecological needs on the installation,
                including the need to provide for the conservation of listed species;
                 (2) A statement of goals and priorities;
                 (3) A detailed description of management actions to be implemented
                to provide for these ecological needs; and
                 (4) A monitoring and adaptive management plan.
                 Among other things, each INRMP must, to the extent appropriate and
                applicable, provide for fish and wildlife management; fish and wildlife
                habitat enhancement or modification; wetland protection, enhancement,
                and restoration where necessary to support fish and wildlife; and
                enforcement of applicable natural resource laws.
                 The National Defense Authorization Act for Fiscal Year 2004 (Pub.
                L. 108-136) amended the Act to limit areas eligible for designation as
                critical habitat. Specifically, section 4(a)(3)(B)(i) of the Act (16
                U.S.C. 1533(a)(3)(B)(i)) provides that the Secretary shall not
                designate as critical habitat any lands or other geographical areas
                owned or controlled by the Department of Defense, or designated for its
                use, that are subject to an integrated natural resources management
                plan prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if
                the Secretary determines in writing that such plan provides a benefit
                to the species for which critical habitat is proposed for designation.
                 We consult with the military on the development and implementation
                of INRMPs for installations with listed species. We analyzed INRMPs
                developed by military installations located within the range of the
                critical habitat designation for yellow lance to determine if they meet
                the criteria for exemption from critical habitat under section 4(a)(3)
                of the Act.
                 We have identified one area within the critical habitat designation
                that consists of Department of Defense lands with a completed, Service-
                approved INRMP. The Army National Guard--Maneuver Training Center Fort
                Pickett (Fort Pickett) is located on 41,000 acres in three counties in
                southeastern Virginia: Nottoway, Brunswick, and Dinwiddie. Fort Pickett
                is on federally owned land, is managed by the Virginia Army National
                Guard, and is subject to all Federal laws and regulations. The Fort
                Pickett INRMP covers fiscal years 2017-2021, updated every five years,
                and serves as the principal management plan governing all natural
                resource activities on the installation. Among the goals and objectives
                listed in the INRMP is habitat management for rare, threatened, and
                endangered species, and the yellow lance is included in this plan.
                Management actions and elements that will benefit the yellow lance and
                its habitat include managing soil erosion and sedimentation;
                maintaining and improving riparian, forest, and stream habitats;
                enforcing stream and wetland protection zones; improving water quality;
                and conducting public outreach and education.
                 Fourteen miles (22.5 km) of Unit 6 (CR1--Nottoway Subbasin) are
                located within the area covered by this INRMP. Based on the above
                considerations, and in accordance with section 4(a)(3)(B)(i) of the
                Act, we have determined that the identified streams are subject to the
                INRMP and that conservation efforts identified in the INRMP will
                provide a benefit to the yellow lance. Therefore, streams within this
                installation are exempt from critical habitat designation under section
                4(a)(3) of the Act. We are not including approximately 14 river miles
                (22.5 km) of habitat in this critical habitat designation because of
                this exemption.
                Consideration of Impacts Under Section 4(b)(2) of the Act
                 Section 4(b)(2) of the Act states that the Secretary shall
                designate and make revisions to critical habitat on the basis of the
                best available scientific data after taking into consideration the
                economic impact, national security impact, and any other relevant
                impact of specifying any particular area as critical habitat. The
                Secretary may exclude an area from critical habitat if he determines
                that the benefits of such exclusion outweigh the benefits of specifying
                such area as part of the critical habitat, unless he determines, based
                on the best scientific data available, that the failure to designate
                such area as critical habitat will result in the extinction of the
                species. In making 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. On December 18, 2020, we
                published a final rule in the Federal Register (85 FR 82376) revising
                portions of our regulations pertaining to exclusions of critical
                habitat. These final regulations became effective on January 19, 2021
                and apply to critical habitat rules for which a proposed rule was
                published after January 19, 2021. Consequently, these new regulations
                do not apply to this final rule.
                 The first sentence in section 4(b)(2) of the Act requires that we
                take into consideration the economic, national security, or other
                relevant impacts of designating any particular area as critical
                habitat. We describe below the process that we undertook for taking
                into consideration each category of impacts and our 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. In order to consider economic impacts of a
                designation, we prepared an incremental effects memorandum (IEM) and
                screening analysis which, together with our narrative and
                interpretation of effects, constitute our final economic analysis (FEA)
                of the critical habitat designation and related factors (IEc 2018,
                entire). We made the analysis, dated September 28, 2018, available for
                public review from February 6, 2020, through April 6, 2020. The DEA
                addressed probable economic impacts of critical habitat for the yellow
                lance. Following the close of the comment period, we reviewed and
                evaluated all information submitted during the comment period that may
                pertain to our consideration of the probable incremental economic
                impacts of this critical habitat designation. Additional information
                relevant to the probable incremental economic impacts of critical
                habitat designation for the yellow lance is summarized below and
                available in the screening analysis for the yellow lance (IEc 2018,
                entire), available at http://www.regulations.gov.
                 The final critical habitat designation for yellow lance totals
                approximately 319 river mi (514 km) in 11 units as critical habitat in
                North Carolina, Virginia, and Maryland, all occupied at the time of
                listing. In these areas, any actions that may affect critical habitat
                would also affect the species, and it is unlikely that any additional
                conservation efforts would be recommended to address the adverse
                modification standard over and above those recommended as necessary to
                avoid jeopardizing the continued existence of yellow lance. Therefore,
                even though some analysis of the impacts of the action of critical
                habitat may be necessary, and this additional analysis will require
                costs in time and resources by both the Federal action agency and the
                Service, it is believed that, in most circumstances, these costs would
                predominantly be administrative in nature and would not be significant.
                [[Page 18200]]
                 The probable incremental economic impacts of the yellow lance
                critical habitat designation are expected to be limited to additional
                administrative effort, as well as minor costs of conservation efforts
                resulting from a small number of future section 7 consultations. This
                low level of impacts is anticipated because, given that the critical
                habitat is occupied by the species, actions that may adversely modify
                the critical habitat would also likely jeopardize the continued
                existence of the species; as a result, other than administrative costs,
                incremental economic impacts of critical habitat designation over and
                above impacts from consulting for jeopardy are unlikely.
                 We do not expect any additional consultations resulting from the
                designation of critical habitat. The total annual incremental costs of
                critical habitat designation are anticipated to be the additional
                resources expended in a maximum of 102 section 7 consultations annually
                at a cost of less than $240,000 per year. Accordingly, we conclude that
                this final designation does not reach the threshold of ``significant''
                under E.O. 12866.
                Exclusions Based on Economic Impacts
                 As discussed above, we considered the economic impacts of the
                critical habitat designation, and the Secretary is not exercising their
                discretion to exclude any areas from this designation of critical
                habitat for the yellow lance based on economic impacts. A copy of the
                IEM and screening analysis with supporting documents may be obtained by
                contacting the Raleigh Ecological Services Field Office (see ADDRESSES)
                or by downloading from the internet at http://www.regulations.gov.
                Exclusions Based on Impacts on National Security and Homeland Security
                 Section 4(a)(3)(B)(i) of the Act (see Exemptions, above) may not
                cover all Department of Defense (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), national-security or homeland-security
                concerns are not a factor in the process of determining what areas meet
                the definition of ``critical habitat.'' Nevertheless, when designating
                critical habitat under section 4(b)(2), the Service must consider
                impacts on national security, including homeland security, on lands or
                areas not covered by section 4(a)(3)(B)(i). Accordingly, we will always
                consider for exclusion from the designation areas for which DoD,
                Department of Homeland Security (DHS), or another Federal agency has
                requested exclusion based on an assertion of national-security or
                homeland-security concerns. We have determined that, other than the
                land exempted under section 4(a)(3)(B)(i) of the Act based upon the
                existence of an approved INRMP (see Exemptions, above), the lands
                within the designation of critical habitat for yellow lance are not
                owned or managed by DoD or DHS, and, therefore, we anticipate no impact
                on national security. Consequently, we did not exclude any areas from
                the final designation based on impacts on national security.
                Exclusions Based on 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. We consider a number of factors including whether there are
                permitted conservation plans covering the species in the area such as
                habitat conservation plans (HCPs), safe harbor agreements, or candidate
                conservation agreements with assurances, or whether there are
                nonpermitted conservation agreements and partnerships that would be
                encouraged by designation of, or exclusion from, critical habitat. In
                addition, we look at the existence of Tribal conservation plans and
                partnerships, and consider the government-to-government relationship of
                the United States with Tribal entities. We also consider any social
                impacts that might occur because of the designation.
                 In preparing this final rule, we determined that there are
                currently no permitted conservation plans or other nonpermitted
                conservation agreements or partnerships for the yellow lance, and the
                final critical habitat designation does not include any Tribal lands or
                trust resources. We anticipate no impact on Tribal lands, partnerships,
                or permitted or nonpermitted plans or agreements from this critical
                habitat designation. Accordingly, we did not exclude any areas from the
                final designation based on other relevant impacts.
                Required Determinations
                Regulatory Planning and Review (Executive Orders 12866 and 13563)
                 Executive Order 12866 provides that the Office of Information and
                Regulatory Affairs in the Office of Management and Budget (OMB) will
                review all significant rules. The Office of Information and Regulatory
                Affairs has determined that this rule is not significant.
                 Executive Order (E.O.) 13563 reaffirms the principles of E.O. 12866
                while calling for improvements in the nation's regulatory system to
                promote predictability, to reduce uncertainty, and to use the best,
                most innovative, and least burdensome tools for achieving regulatory
                ends. The executive order directs agencies to consider regulatory
                approaches that reduce burdens and maintain flexibility and freedom of
                choice for the public where these approaches are relevant, feasible,
                and consistent with regulatory objectives. E.O. 13563 emphasizes
                further that regulations must be based on the best available science
                and that the rulemaking process must allow for public participation and
                an open exchange of ideas. We have developed this rule in a manner
                consistent with these requirements.
                Regulatory Flexibility Act (5 U.S.C. 601 et seq.)
                 Under the Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.),
                as amended by the Small Business Regulatory Enforcement Fairness Act of
                1996 (SBREFA; 5 U.S.C. 801 et seq.), whenever an agency is required to
                publish a notice of rulemaking for any proposed or final rule, it must
                prepare and make available for public comment a regulatory flexibility
                analysis that describes the effects of the rule on small entities
                (i.e., small businesses, small organizations, and small government
                jurisdictions). However, no regulatory flexibility analysis is required
                if the head of the agency certifies the rule will not have a
                significant economic impact on a substantial number of small entities.
                The SBREFA amended the RFA to require Federal agencies to provide a
                certification statement of the factual basis for certifying that the
                rule will not have a significant economic impact on a substantial
                number of small entities.
                 According to the Small Business Administration, small entities
                include small organizations such as independent nonprofit
                organizations; small governmental jurisdictions, including school
                boards and city and town governments that serve fewer than 50,000
                residents; and small businesses (13 CFR 121.201). Small businesses
                include manufacturing and mining concerns with fewer than 500
                employees, wholesale trade entities with fewer than 100 employees,
                retail and service businesses with less than $5 million in annual
                sales, general and heavy construction businesses with less than $27.5
                million in annual business,
                [[Page 18201]]
                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 only required to evaluate the
                potential incremental impacts of rulemaking on those entities directly
                regulated by the rulemaking itself and, therefore, are not required to
                evaluate the potential impacts to indirectly regulated entities. The
                regulatory mechanism through which critical habitat protections are
                realized is section 7 of the Act, which requires Federal agencies, in
                consultation with the Service, to ensure that any action authorized,
                funded, or carried 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 will be directly regulated by this
                designation. There is no requirement under the RFA to evaluate the
                potential impacts to entities not directly regulated. Moreover, Federal
                agencies are not small entities. Therefore, because no small entities
                will be directly regulated by this rulemaking, the Service certifies
                that this critical habitat designation will not have a significant
                economic impact on a substantial number of small entities and a
                regulatory flexibility analysis is not required.
                Energy Supply, Distribution, or Use--Executive Order 13211
                 Executive Order 13211 (Actions Concerning Regulations That
                Significantly Affect Energy Supply, Distribution, or Use) requires
                agencies to prepare Statements of Energy Effects when undertaking
                certain actions. OMB has provided guidance for implementing this E.O.
                that outlines nine outcomes that may constitute ``a significant adverse
                effect'' when compared to not taking the regulatory action under
                consideration. The economic analysis finds that none of these criteria
                is relevant to this analysis. Thus, based on information in the
                economic analysis, energy-related impacts associated with yellow lance
                conservation activities within critical habitat are not expected. As
                such, the designation of critical habitat is not expected to
                significantly affect energy supplies, distribution, or use. Therefore,
                this action is not a significant energy action, and no Statement of
                Energy Effects is required.
                Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)
                 In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501
                et seq.), we make the following findings:
                 (1) This rule will not produce a Federal mandate. In general, a
                Federal mandate is a provision in legislation, statute, or regulation
                that would impose an enforceable duty upon State, local, or Tribal
                governments, or the private sector, and includes both ``Federal
                intergovernmental mandates'' and ``Federal private sector mandates.''
                These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal
                intergovernmental mandate'' includes a regulation that ``would impose
                an enforceable duty upon State, local, or tribal governments'' with two
                exceptions. It excludes ``a condition of Federal assistance.'' It also
                excludes ``a duty arising from participation in a voluntary Federal
                program,'' unless the regulation ``relates to a then-existing Federal
                program under which $500,000,000 or more is provided annually to State,
                local, and tribal governments under entitlement authority,'' if the
                provision would ``increase the stringency of conditions of assistance''
                or ``place caps upon, or otherwise decrease, the Federal Government's
                responsibility to provide funding,'' and the State, local, or Tribal
                governments ``lack authority'' to adjust accordingly. At the time of
                enactment, these entitlement programs were: Medicaid; Aid to Families
                with Dependent Children work programs; Child Nutrition; Food Stamps;
                Social Services Block Grants; Vocational Rehabilitation State Grants;
                Foster Care, Adoption Assistance, and Independent Living; Family
                Support Welfare Services; and Child Support Enforcement. ``Federal
                private sector mandate'' includes a regulation that ``would impose an
                enforceable duty upon the private sector, except (i) a condition of
                Federal assistance or (ii) a duty arising from participation in a
                voluntary Federal program.''
                 The designation of critical habitat does not impose a legally
                binding duty on non-Federal Government entities or private parties.
                Under the Act, the only regulatory effect is that Federal agencies must
                ensure that their actions do not destroy or adversely modify critical
                habitat under section 7. While non-Federal entities that receive
                Federal funding, assistance, or permits, or that otherwise require
                approval or authorization from a Federal agency for an action, may be
                indirectly impacted by the designation of critical habitat, the legally
                binding duty to avoid destruction or adverse modification of critical
                habitat rests squarely on the Federal agency. Furthermore, to the
                extent that non-Federal entities are indirectly impacted because they
                receive Federal assistance or participate in a voluntary Federal aid
                program, the Unfunded Mandates Reform Act would not apply, nor would
                critical habitat shift the costs of the large entitlement programs
                listed above onto State governments.
                 (2) We do not believe that this rule will significantly or uniquely
                affect small governments because most of the lands adjacent to the
                streams being designated as critical habitat are owned by private
                landowners. These entities do not fit the definition of ``small
                governmental jurisdiction.'' The riparian habitat owned by Federal,
                State, or local governments that we are designating as critical habitat
                in this rule are either lands managed for conservation or lands already
                developed. Consequently, we do not believe that the critical habitat
                designation will significantly or uniquely affect small government
                entities. As such, a Small Government Agency Plan is not required.
                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 yellow lance 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
                [[Page 18202]]
                would destroy or adversely modify critical habitat. A takings
                implications assessment has been completed and concludes that this
                designation of critical habitat for yellow lance 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 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 the critical habitat designation with, the
                appropriate State resource agencies. We did not receive comments from
                the States. From a federalism perspective, the designation of critical
                habitat directly affects only the responsibilities of Federal agencies.
                The Act imposes no other duties with respect to critical habitat,
                either for States and local governments, or for anyone else. As a
                result, the rule does not have substantial direct effects either on the
                State, or on the relationship between the Federal Government and the
                State, or on the distribution of powers and responsibilities among the
                various levels of government. The designation may have some benefit to
                these governments because the areas that contain the features essential
                to the conservation of the species are more clearly defined, and the
                physical 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 these local governments no longer have to
                wait for case-by-case section 7 consultations to occur).
                 Where State and local governments require approval or authorization
                from a Federal agency for actions that may affect critical habitat,
                consultation under section 7(a)(2) will be required. While non-Federal
                entities that receive Federal funding, assistance, or permits, or that
                otherwise require approval or authorization from a Federal agency for
                an action, may be indirectly impacted by the designation of critical
                habitat, the legally binding duty to avoid destruction or adverse
                modification of critical habitat rests squarely on the Federal agency.
                Civil Justice Reform--Executive Order 12988
                 In accordance with Executive Order 12988 (Civil Justice Reform),
                the Office of the Solicitor has determined that the rule does not
                unduly burden the judicial system and that it meets the requirements of
                sections 3(a) and 3(b)(2) of the Order. We are designating critical
                habitat in accordance with the provisions of the Act. To assist the
                public in understanding the habitat needs of the species, this rule
                identifies the elements of physical or biological features essential to
                the conservation of the species. The designated areas of critical
                habitat are presented on maps, and the rule provides several options
                for the interested public to obtain more detailed location information,
                if desired.
                Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)
                 This rule does not contain 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.)
                 It is our position that, outside the jurisdiction of the U.S. Court
                of Appeals for the Tenth Circuit, we do not need to prepare
                environmental analyses pursuant to the National Environmental Policy
                Act in connection with designating critical habitat under the Act. We
                published a notice outlining our reasons for this determination in the
                Federal Register on October 25, 1983 (48 FR 49244). This position was
                upheld by the U.S. Court of Appeals for the Ninth Circuit (Douglas
                County v. Babbitt, 48 F.3d 1495 (9th Cir. 1995), cert. denied 516 U.S.
                1042 (1996)).
                Government-to-Government Relationship With Tribes
                 In accordance with the President's memorandum of April 29, 1994
                (Government-to-Government Relations with Native American Tribal
                Governments; 59 FR 22951), Executive Order 13175 (Consultation and
                Coordination With Indian Tribal Governments), and the Department of the
                Interior's manual at 512 DM 2, we readily acknowledge our
                responsibility to communicate meaningfully with recognized Federal
                Tribes on a government-to-government basis. In accordance with
                Secretarial Order 3206 of June 5, 1997 (American Indian Tribal Rights,
                Federal-Tribal Trust Responsibilities, and the Endangered Species Act),
                we readily acknowledge our responsibilities to work directly with
                Tribes in developing programs for healthy ecosystems, to acknowledge
                that Tribal lands are not subject to the same controls as Federal
                public lands, to remain sensitive to Indian culture, and to make
                information available to Tribes. We have identified no Tribal interests
                that will be affected by this rule.

                Yellow Lance (Elliptio lanceolata)
                 (1) Critical habitat units are depicted for Franklin, Granville,
                Halifax, Johnston, Nash, Vance, Wake, and Warren Counties, North
                Carolina; Brunswick, Craig, Culpeper, Dinwiddie, Fauquier, Louisa,
                Lunenburg, Madison, Nottoway, Orange, and Rappahannock Counties,
                Virginia; and Howard and Montgomery Counties, Maryland, on the maps in
                this entry.
                 (2) Within these areas, the physical or biological features
                essential to yellow lance conservation consist of the following
                components:
                 (i) Suitable substrates and connected instream habitats,
                characterized by geomorphically stable stream channels and banks (i.e.,
                channels that maintain lateral dimensions, longitudinal profiles, and
                sinuosity patterns over time without an aggrading or degrading bed
                elevation) with habitats that support a diversity of freshwater mussel
                and native fish (such as stable riffle-run-pool habitats that provide
                flow refuges consisting of silt-free gravel and coarse sand
                substrates).
                 (ii) Adequate flows, or a hydrologic flow regime (which includes
                the severity, frequency, duration, and seasonality of discharge over
                time), necessary to maintain benthic habitats where the species is
                found and to maintain connectivity of streams with the floodplain,
                allowing the exchange of nutrients and sediment for maintenance of the
                mussel's and fish host's habitat, food availability, spawning habitat
                for native fishes, and the ability for newly transformed juveniles to
                settle and become established in their habitats.
                 (iii) Water and sediment quality (including, but not limited to,
                conductivity, hardness, turbidity, temperature, pH, ammonia, heavy
                metals, and chemical constituents) necessary to sustain natural
                physiological processes for normal behavior, growth, and viability of
                all life stages.
                 (iv) The presence and abundance of fish hosts necessary for yellow
                lance recruitment.
                 (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
                May 10, 2021.
                 (4) Critical habitat map units. Data layers defining map units were
                created by overlaying Natural Heritage Element Occurrence data and U.S.
                Geological Survey (USGS) hydrologic data for stream reaches. The
                hydrologic data used in the critical habitat maps were extracted from
                the USGS 1:1M scale nationwide hydrologic layer (https://nationalmap.gov/small_scale/mld/1nethyd.html) with a projection of
                EPSG:4269-NAD83 Geographic. The North Carolina, Virginia, and Maryland
                Natural Heritage program species presence data were used to select
                specific stream segments for inclusion in the critical habitat layer.
                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 http://www.regulations.gov under Docket No.
                FWS-R4-ES-2018-0094 and at the Raleigh Ecological Services Field
                Office. 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.
