    This appeal concerns the United States Fish and Wildlife Service’s (the
    “Service”) decision to modify certain trail paths in the Rocky Flats National Wildlife
    Refuge (the “Refuge”).
    Appellants1 are organizations that challenge the Service’s 2018 decision to
    modify trails in the Refuge that have been designated for public use. Led by the
    Rocky Mountain Peace and Justice Center (the “Center”),2 they sued the Service and
    others,3 claiming they failed to comply with various federal statutes and regulations,
    including the National Environmental Policy Act of 1969 (“NEPA”) and the
    1
    Rocky Mountain Peace and Justice Center, Candelas Glows/Rocky Flats
    Glows, Rocky Flats Right to Know, Rocky Flats Neighborhood Association, and
    Environmental Information Network (EIN) Inc.
    2
    We refer to Appellants collectively as “the Center.”
    3
    The suit named the United States Federal Highway Administration and
    several officials in their official capacities. We refer to Appellees collectively as
    “the Service.”

    Appellate Case: 21-1310    Document: 010110713092         Date Filed: 07/19/2022     Page: 3
    Endangered Species Act of 1973 (“ESA”). The Center also moved for a preliminary
    injunction and for the district court to supplement the administrative record and
    consider evidence from outside the record. The district court denied the Center’s
    NEPA claims, dismissed its ESA claim for lack of standing, and denied its motions.
    Exercising jurisdiction under 
    28 U.S.C. § 1291
    , we affirm.
    I. BACKGROUND
    We describe relevant statutes and regulations, summarize the factual and
    procedural history, and then turn to our analysis.
    A. Relevant Statutes and Regulations
    Three statutes and their implementing regulations are relevant for this appeal:
    (1) the Administrative Procedure Act (“APA”), (2) NEPA, and (3) the ESA.
    The Administrative Procedure Act
    The APA provides a private right of action to challenge agency actions that
    violate NEPA. Utah Env’t Cong. v. Russell, 
    518 F.3d 817
    , 823 (10th Cir. 2008).
    Under the APA, a “person suffering legal wrong because of agency action, or
    adversely affected or aggrieved by agency action . . . , is entitled to judicial review
    thereof.” 
    5 U.S.C. § 702
    . A court will set aside an agency action if it is “arbitrary,
    capricious, an abuse of discretion, or otherwise not in accordance with law.”
    
    Id.
     § 706(2)(A).
    An agency action is arbitrary and capricious if the agency “entirely failed to
    consider an important aspect of the problem, offered an explanation for its decision
    that runs counter to the evidence before the agency, or is so implausible that it could
    3
    Appellate Case: 21-1310    Document: 010110713092         Date Filed: 07/19/2022    Page: 4
    not be ascribed to a difference in view or the product of agency expertise.” Motor
    Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983).
    The National Environmental Policy Act
    “NEPA established a national policy to promote the understanding of the
    ecological systems and natural resources important to the United States, and thereby
    reduce or eliminate environmental damage.” Biodiversity Conservation All. v. Jiron,
    
    762 F.3d 1036
    , 1050 (10th Cir. 2014) (quotations omitted).
    “NEPA does not provide for a private right of action,” so we review a NEPA
    challenge under the standards set forth in the APA. Colo. Farm Bureau Fed’n v.
    U.S. Forest Serv., 
    220 F.3d 1171
    , 1173 (10th Cir. 2000). “NEPA does not mandate
    particular results or create substantive limits.” Biodiversity Conservation All., 762
    F.3d at 1050. It instead “imposes only procedural requirements on federal agencies
    with a particular focus on requiring agencies to undertake analyses of the
    environmental impact of their proposals and actions.” Dep’t of Transp. v. Pub.
    Citizen, 
    541 U.S. 752
    , 756-57 (2004). We summarize the relevant procedural
    requirements.
    The EIS and preparation of the supplemental EIS
    A federal agency must prepare an environmental impact statement (“EIS”)
    before it takes a “major Federal action[] significantly affecting the quality of the
    human environment.” 
    42 U.S.C. § 4332
    (C). The EIS must provide “a detailed
    statement” on (i) “the environmental impact of the proposed action,” (ii) “any
    adverse environmental effects which cannot be avoided,” (iii) “alternatives to the
    4
    Appellate Case: 21-1310      Document: 010110713092       Date Filed: 07/19/2022    Page: 5
    proposed action,” (iv) “the relationship between local short-term uses of man’s
    environment and . . . enhancement of long-term productivity,” and (v) “any
    irreversible and irretrievable commitments of resources which would be involved in
    the proposed action.” 
    Id.
    The Council on Environmental Quality (“CEQ”) has promulgated regulations
    governing the preparation of an EIS. 
    40 C.F.R. §§ 1500-1508.28.4
     The agency
    preparing the EIS must “[r]igorously explore and objectively evaluate all reasonable
    alternatives,” “[i]nclude the alternative of no action,” and “if one or more exists,”
    “[i]dentify the agency’s preferred alternative.” 
    Id.
     § 1502.14(a), (d), (e).
    After an agency has issued an EIS, it must prepare a supplemental EIS if
    (1) “[t]he agency makes substantial changes in the proposed action that are relevant
    to environmental concerns” or (2) “[t]here are significant new circumstances or
    information relevant to environmental concerns and bearing on the proposed action
    or its impacts.” Id. § 1502.9(c)(1)(i)-(ii).
    Once the agency has completed its EIS and supplemental EIS as needed, it
    must wait a prescribed period of time before it may make a decision on the proposed
    action. Id. § 1506.10. When the agency makes a decision, it “shall prepare a concise
    public record of decision [‘ROD’],” which must (1) “[s]tate what the decision was,”
    (2) “[i]dentify all alternatives considered by the agency in reaching its decision,” and
    4
    The CEQ revised the NEPA regulations in 2020, but the 2018 regulations
    applied to this case. We cite to the 2018 regulations accordingly.
    5
    Appellate Case: 21-1310    Document: 010110713092        Date Filed: 07/19/2022    Page: 6
    (3) “[s]tate whether all practicable means to avoid or minimize environmental harm
    from the alternative selected have been adopted.” Id. § 1505.2.
    Exceptions to the EIS requirement
    When an agency is uncertain as to whether a new project warrants an EIS, it
    may prepare an environmental assessment (“EA”), a concise statement that presents
    evidence explaining whether an EIS is necessary. Id. §§ 1501.3, 1508.9. “[I]f the
    agency determines on the basis of the environmental assessment not to prepare” an
    EIS, then it must prepare a finding of no significant impact (“FONSI”). Id.
    § 1501.4(e). A FONSI is “a document by a federal agency briefly presenting the
    reasons why an action . . . will not have a significant effect on the human
    environment and for which an [EIS] therefore will not be prepared.” Id. § 1508.13.
    An agency may also identify categorical exclusions of actions that do not
    require preparation of either an EA or an EIS. A categorical exclusion “means a
    category of actions which do not individually or cumulatively have a significant
    effect on the human environment.” Id. § 1508.4. To establish these categorical
    exclusions, the agency must determine that such projects have no major
    environmental effect. Id. But the agency must also allow “for extraordinary
    circumstances in which a normally excluded action may have a significant
    environmental effect.” Id. In such extraordinary circumstances, an agency cannot
    rely on the categorical exclusions to avoid preparing an EA or an EIS.
    6
    Appellate Case: 21-1310       Document: 010110713092     Date Filed: 07/19/2022        Page: 7
    The Department of Interior has set forth categorical exclusions in its
    Departmental Manual. 516 DM § 8. Under the Manual, the Service does not have to
    conduct an additional NEPA analysis if the proposed action consists of:
    1) “[m]inor changes in the amounts or types of public use on Service or State-
    managed lands, in accordance with existing regulations, management plans,
    and procedures,”
    2) “[m]inor changes in existing master plans, comprehensive conservation
    plans, or operations, when no or minor effects are anticipated,” or
    3) “[t]he issuance of new or revised site, unit, or activity-specific management
    plans for public use, land use, or other management activities when only
    minor changes are planned.”
    Id. § 8.5(B)(7), (9)-(10).
    As noted, the Service cannot rely on categorical exclusions if certain
    extraordinary circumstances apply, including when the proposed action may have
    (1) “significant impacts on public health or safety,” or (2) “highly controversial
    environmental effects.” 
    43 C.F.R. § 46.215
    (a), (c).
    The Endangered Species Act
    “The Endangered Species Act of 1973 is intended to protect and conserve
    endangered and threatened species and their habitats.” Nat’l Ass’n of Home Builders
    v. Defs. of Wildlife, 
    551 U.S. 644
    , 651 (2007) (citation omitted). “Section 7 of the
    ESA prescribes the steps that federal agencies must take to ensure that their actions
    do not jeopardize endangered wildlife and flora.” 
    Id. at 652
    . An agency must ensure
    its actions are (1) “not likely to jeopardize the continued existence of any endangered
    species” or (2) not likely to “result in the destruction or adverse modification of
    7
    Appellate Case: 21-1310      Document: 010110713092          Date Filed: 07/19/2022     Page: 8
    habitat of such species which is determined . . . to be critical.” 
    16 U.S.C. § 1536
    (a)(2).
    Once an agency determines that its action “is likely to jeopardize” an
    endangered species or its habitat, it must consult with the Service. 
    50 C.F.R. § 402.10
    (a). This consultation may be formal or informal. 
    Id.
     §§ 402.13 (informal),
    402.14 (formal). If, after the consultation, the Service determines “that the action is
    not likely to adversely affect listed species or critical habitat, . . . no further action is
    necessary.” Id. § 402.13(c); see also id. § 402.14(m)(3). But if the Service
    concludes that the proposed action may jeopardize an endangered species or its
    habitat, the agency must either terminate the action, implement a proposed
    alternative, or seek an exemption. Rio Grande Silvery Minnow v. Bureau of
    Reclamation, 
    601 F.3d 1096
    , 1106 (10th Cir. 2010).
    Unlike NEPA, the ESA provides a private right of action to challenge agency
    actions that violate the statute’s provisions. 
    16 U.S.C. § 1540
    (g)(1).
    B. Factual History
    We begin by recounting the history of the Refuge and the cleanup efforts.
    We then summarize the ensuing administrative actions regarding use of the Refuge.
    History of the Refuge
    The Rocky Flats National Wildlife Refuge covers approximately 6,200 acres
    of land surrounding a former nuclear defense facility operated by the U.S.
    Department of Energy (“DOE”). AR 1343. From 1951 to 1989, DOE manufactured
    8
    Appellate Case: 21-1310     Document: 010110713092       Date Filed: 07/19/2022    Page: 9
    nuclear weapons in an area in the middle of the site known as the Industrial Area.
    AR 1353.
    In 1989, the Environmental Protection Agency (“EPA”) added the site to the
    CERCLA National Priorities List5 because production at the facility released
    hazardous substances, including radionuclides,6 into the surrounding area. AR 5518.
    By placing the site on the National Priorities List, EPA committed to a large-scale
    cleanup operation.
    During the 1990s and early 2000s, EPA coordinated the cleanup process with
    DOE and the Colorado Department of Public Health and Environment (“CDPHE”).
    AR 1353. As part of this process, the agencies collected thousands of soil samples to
    test radionuclide levels in the soil. After consultation with local stakeholders, they
    set the cleanup standard for eventual public use of the Refuge at 50 picoCuries per
    gram (pCi/g).7 AR 5718, 5528. At 50 pCi/g, Refuge workers8 would have an
    5
    CERCLA stands for the Comprehensive Environmental Response,
    Compensation, and Liability Act, 
    42 U.S.C. §§ 9601-9675
    . The CERCLA National
    Priorities List contains “national priorities among the known releases or threatened
    releases of hazardous substances, pollutants, or contaminants throughout the United
    States.” 
    54 Fed. Reg. 41,015
    , 41,015 (Oct. 4, 1989).

    Radionuclides are atoms that emit radiation as they undergo radioactive
    decay through the emission of alpha particles, beta particles, or gamma rays.
    7
    A pCi/g is a measure of the rate of radioactive decay of plutonium.
    8
    Refuge workers were defined as individuals who worked four hours indoors
    and four hours outdoors in the area for 250 days each year for 18.7 years. AR 1094.
    9
    Appellate Case: 21-1310    Document: 010110713092       Date Filed: 07/19/2022    Page: 10
    increased cancer risk of around 1 in 133,300. AR 1094. For Refuge visitors, 9 it
    would be around 1 in 227,000. 
    Id.
     The agencies deemed any exposure levels below
    50 pCi/g fall within the acceptable risk range. AR 5528. This map shows pre-
    cleanup pCi/g concentration levels in the site:
    AR 1362.
    9
    Refuge visitors were defined as (1) children who were outside for 2.5 hours
    for 100 days a year for six years or (2) adults who were outside for 2.5 hours for 100
    days a year for 24 years. AR 1094.
    10
    Appellate Case: 21-1310     Document: 010110713092         Date Filed: 07/19/2022    Page: 11
    In 2001, while cleanup was ongoing, Congress enacted the Rocky Flats
    National Wildlife Refuge Act, Pub. L. No. 107-107, 
    115 Stat. 1012
    . Under the Act,
    DOE “was to manage the” Industrial Area, and “the balance of the Flats was to
    become a National Wildlife Refuge run by the Service.” WildEarth Guardians v.
    U.S. Fish & Wildlife Serv., 
    784 F.3d 677
    , 681 (10th Cir. 2015). Congress directed
    DOE to “transfer to the Service administrative jurisdiction of the land marked for
    refuge status as soon as the EPA determined the cleanup was complete.” 
    Id.
    The 2004 Comprehensive Conservation Plan and Environmental Impact
    Statement
    In 2004, the Service issued the Final Comprehensive Conservation Plan and
    Environmental Impact Statement (“2004 CCP/EIS”), which confirmed that DOE was
    completing the cleanup under EPA’s and CDPHE’s oversight. AR 1353. It also
    confirmed that after completion of the cleanup, DOE would transfer jurisdiction to
    the Service. AR 1353-54. It noted that “[t]he majority of the site has remained
    undisturbed since its acquisition, and provides habitat for . . . two species that are
    federally listed as threatened (bald eagle and Preble’s meadow jumping mouse).”
    AR 1354.
    The 2004 CCP/EIS set six goals for Refuge management, including public use.
    AR 1357. It acknowledged that “the estimated increased cancer risk from exposure
    to residual soil contamination of 7 pCi/g is 1 in 1 million for the Refuge worker and
    0.6 in 1 million . . . for the Refuge visitor,” but concluded that “the majority of the
    public use facilities would be located in areas where the residual contamination is
    11
    Appellate Case: 21-1310     Document: 010110713092       Date Filed: 07/19/2022    Page: 12
    much lower (less than 1 pCi/g).” AR 1363. Under the 2004 CCP/EIS’s preferred
    alternative, public use “would include about 16 miles of trails, a seasonally staffed
    visitor contact station, trailheads with parking, and developed overlooks.” AR 1368.
    Most of these trails “would use existing road corridors,” and the public could access
    these trails by foot, bicycle, or horse. 
    Id.
     The following map in the 2004 CCP/EIS
    depicts the proposed trails:
    AR 1373.
    In 2005, the Service issued the ROD, which adopted the preferred alternative
    in the 2004 CCP/EIS for public use. AR 1312-26. Cleanup efforts continued, and in
    2007, EPA certified that the cleanup had reached the point where DOE would
    transfer the Refuge (excluding the Industrial Area) to the Service. 
    72 Fed. Reg. 29,276
    , 29,276 (May 25, 2007). In doing so, EPA “determined that the
    12
    Appellate Case: 21-1310     Document: 010110713092       Date Filed: 07/19/2022       Page: 13
    [relevant portion of the Refuge] poses no significant threat to public health or the
    environment and, therefore, no further remedial measures pursuant to CERCLA are
    appropriate.” 
    Id.
     It left the Industrial Area on the National Priorities List and under
    DOE’s jurisdiction. 
    Id.
     The Service took control of the remainder of the Refuge.
    AR 4.
    The Section 16 Parcel
    In 2011, the Service began studying whether to acquire an approximately
    640-acre parcel adjacent to the southwest boundary of the Refuge (the “Section 16
    Parcel”). AR 1045. Several mines, including a clay mine and a coal mine,
    previously operated on the Section 16 Parcel, but no nuclear activities occurred there.
    AR 1041.
    The Service conducted a site assessment consisting of “research, sampling, and
    site visits,” which “found no known or observable environmental contaminant[]
    issues related to the parcel.” AR 1038. As part of this assessment, the Service relied
    on soil samples taken from the Refuge in 2006. AR 1047. The soil samples, which
    were “collected adjacent to the northern and eastern property boundaries” of the
    Section 16 Parcel—closer to the Industrial Area—“yielded actinide concentrations
    well below 1 pCi/g.” 
    Id.
     During the site visits, the Service identified a “rusted
    storage barrel” that “appears to be empty” near a pond within the State Clay Mine.
    AR 1048; see also AR 1054. It recommended the barrel’s removal. AR 1038.
    13
    Appellate Case: 21-1310   Document: 010110713092        Date Filed: 07/19/2022   Page: 14
    On December 2, 2011, the Service prepared an EA evaluating whether to
    expand the Refuge to include the Section 16 Parcel. AR 1000-03. The Service
    concluded that the proposed annexation:
    1) “would pose minimal risk to public health and safety;”
    2) was “not highly controversial;” and
    3) after performing “a formal intra-Service section 7 consultation,” the
    proposed action “will not result in the jeopardy of any federally threatened
    or endangered species, or adversely modify existing designated critical
    habitat,” including for the Preble’s meadow jumping mouse.
    AR 1002. The EA made a finding of no significant impact—a FONSI—and therefore
    concluded that the Service did not need to prepare a supplemental EIS. AR 1004.
    The Service finalized the annexation of the Section 16 Parcel in 2012.
    AR 432.
    The 2018 Environmental Action Statement
    In 2018, the Service issued an Environmental Action Statement (“2018 EAS”),
    which is the agency action challenged here. The Service prepares an EAS instead of
    an EA when it concludes the action falls within a categorical exclusion but may be
    controversial. 550 FW § 3.3(C)(2)(b). Two aspects of the 2018 EAS are relevant to
    that challenge: (1) the actual changes the Service made to the 2004 CCP/EIS, and (2)
    certain proposed changes the Service might consider in the future.
    Changes made in the 2018 EAS
    In the 2018 EAS, the Service made changes to the trail configurations
    proposed in the 2004 CCP/EIS. Among them was modification of the Rocky
    14
    Appellate Case: 21-1310    Document: 010110713092       Date Filed: 07/19/2022    Page: 15
    Mountain Greenway trail, an eight-mile trail that would run from the northern border
    of the Refuge to the southwest, then continue eastward to the south of the Industrial
    Area. AR 7. The 2018 EAS added about one mile to the Rocky Greenway trail,
    extending it into the Section 16 Parcel “to provide access to the historic Caprock
    Mine.” Id.10 The Service included the following map to show the revised trail paths:
    10
    The 2018 EAS also (1) transformed the Walnut Creek trail into a loop; (2)
    changed the path of the Rock Creek trail; (3) converted the Lindsay Ranch Loop,
    East Woman Creek Loop, and East Woman Creek Connector trails to multiple use
    trails; (4) prohibited the off-trail use of the southern part of the Refuge; and (5)
    established sensitive wildlife areas in Walnut Creek, Rock Creek, and Antelope

    Id.11
    The Service determined the trail modifications were eligible for three
    categorical exclusions because they were (1) “minor changes in the amounts or types
    of public use on Service . . . lands, in accordance with existing regulations,
    management plans, and procedures”; (2) “minor changes in existing master plans,
    comprehensive conservation plans, or operations, when no or minor effects are
    anticipated”; and (3) were part of “the issuance of new or revised site, unit, or
    activity-specific management plans for public use, land use, or other management
    activities when only minor changes are planned.” AR 9. The Service thus
    determined the trail modifications did not merit preparation of an EA or an EIS.
    AR 1.
    The Service also concluded that the changes did not involve any extraordinary
    circumstances prohibiting the use of the categorical exclusions. AR 9-10.
    Potential changes suggested in the 2018 EAS
    The Service also identified potential changes to the eastern portion of the
    Rocky Mountain Greenway trail.12 AR 8. One change would shift the eastern part of
    the trail northward into an area to the east of the Industrial Area known as the Wind
    11
    The Rocky Mountain Greenway is highlighted in green. The one-mile
    addition to the Rocky Mountain Greenway trail appears in the southwest corner of
    the map.

    This proposed change is reflected in the map above in the red box to the east
    of the Industrial Area.

    Blown Area.13 The Service also suggested adding an access point to the Refuge in
    the Wind Blown Area.
    The Service excluded these changes from its 2018 EAS analysis, emphasizing
    they “may or may not occur in the future,” AR 6, so “[i]f these items proceed, an
    additional NEPA determination will be required,” AR 8.
    C. Procedural History
    Shortly after issuance of the 2018 EAS, the Center sued, claiming violations of
    the APA, NEPA, the ESA, and the National Wildlife Refuge Systems Administration
    Act (the “Refuge Act”). It alleged that the Service:
    1) should have prepared a new or supplemental EIS based on the significance
    of the approved trail modifications,
    2) incorrectly concluded the approved changes were not extraordinary
    circumstances and thus erroneously relied on the use of the categorical
    exclusions,14
    3) improperly excluded the proposed trail modification in the Wind Blown
    Area from the NEPA analysis,
    4) failed to adequately consult with the relevant agencies under Section 7 of
    the ESA regarding the Preble’s meadow jumping mouse when it made the
    changes to the trails, and
    5) violated the Refuge Act by opening the Refuge for trail use.
    13
    The Center and the Service both use “Wind Blown Area” to refer to the
    eastern portion of the Refuge that is downwind of the Industrial Area. See Aplt. Br.
    at xii; Aplee Br. at 13 n.7, 32.
    14
    The Center presented six extraordinary circumstances at the district court,
    but it abandoned four of them on appeal. Compare App. at 1000-04 with Aplt. Br.
    at 29.
    17
    Appellate Case: 21-1310    Document: 010110713092        Date Filed: 07/19/2022     Page: 18
    The Center moved for a preliminary injunction to block construction of the
    trails and the opening of the Refuge. After holding an evidentiary hearing, the
    district court denied the motion, finding that the Center failed to show irreparable
    harm. The court also dismissed the Center’s ESA claim because it did not have
    standing.
    The Center asked the district court to supplement the administrative record.
    It argued the Service improperly excluded:
    1) a 2012 study by Marco Kaltofen regarding plutonium exposure levels on
    the eastern part of the Refuge (the “2012 Kaltofen Study”),
    2) a 2006 jury verdict form from a trial finding two corporate defendants
    liable for trespassing on plaintiffs’ property to the east of the Refuge by
    exposing the property to plutonium (the “Cook verdict form”),
    3) a 2011 email chain between Service officials discussing a possible trail
    alteration close to the “plutonium plume” (the “2011 email chain”), and
    4) a 2018 declaration by Harvey Nichols regarding plutonium testing in the
    1970s.
    The Center also asked the district court to consider extra-record evidence
    before deciding the merits. It pointed to
    1) testimony from witnesses at the preliminary injunction hearing,
    2) a memorandum regarding the Service’s decision to relocate prairie dogs to
    the Refuge, and
    3) soil sampling taken in 2019 that indicated elevated levels of plutonium to
    the east of the Refuge.
    It argued this evidence undermined the 2018 EAS.
    18
    Appellate Case: 21-1310     Document: 010110713092        Date Filed: 07/19/2022    Page: 19
    After briefing on the merits, the district court denied the Center’s remaining
    claims. It also rejected the Center’s requests to supplement the administrative record
    and to consider extra-record evidence. The Center timely appealed.
    II. DISCUSSION
    The Center challenges the district court’s (A) dismissal of its ESA claim for
    lack of standing, (B) denial of its petition for review regarding its NEPA claims, and
    (C) refusal to supplement the record or consider extra-record evidence.15
    A. Standing
    We first address the Center’s standing to bring its NEPA and ESA claims.16 We
    review “a district court’s rulings on Article III standing de novo.” Safe Streets All. v.
    Hickenlooper, 
    859 F.3d 865
    , 878 (10th Cir. 2017) (quotations omitted).
    Legal Framework
    “No principle is more fundamental to the judiciary’s proper role in our system
    of government than the constitutional limitation of federal-court jurisdiction to actual
    cases or controversies.” Raines v. Byrd, 
    521 U.S. 811
    , 818 (1997) (quotations
    omitted). “One element of the case-or-controversy requirement is that plaintiffs must
    15
    The Center abandoned its other claims on appeal, including its Refuge Act
    claims.
    16
    The Service did not initially contest the Center’s standing to bring the NEPA
    claims. We sua sponte ordered the parties to file supplemental briefing addressing
    the Center’s NEPA standing.
    19
    Appellate Case: 21-1310     Document: 010110713092        Date Filed: 07/19/2022       Page: 20
    establish that they have standing to sue.” Clapper v. Amnesty Int’l USA, 
    568 U.S. 398
    , 408 (2013) (quotations omitted).
    The plaintiff “bear[s] the burden of establishing standing,” Colo. Outfitters
    Ass’n v. Hickenlooper, 
    823 F.3d 537
    , 544 (10th Cir. 2016), and must have “standing
    . . . at the time the action is brought,” Mink v. Suthers, 
    482 F.3d 1244
    , 1253 (10th
    Cir. 2007). “Standing must exist throughout the litigation.” Qwest Commc’ns Int’l,
    Inc. v. F.C.C., 
    240 F.3d 886
    , 891 (10th Cir. 2001).
    “[T]he irreducible constitutional minimum of standing consists of three
    elements. The plaintiff must have (1) suffered an injury in fact, (2) that is fairly
    traceable to the challenged conduct of the defendant, and (3) that is likely to be
    redressed by a favorable judicial decision.” Spokeo, Inc. v. Robins, 
    578 U.S. 330
    ,
    338 (2016) (quotations and citations omitted).
    First, the plaintiff must allege that it suffered an injury in fact, which must be
    (1) “concrete and particularized” and (2) “actual or imminent, not conjectural or
    hypothetical.” 
    Id. at 339
     (quoting Lujan v. Defs. of Wildlife, 
    504 U.S. 555
    , 560
    (1992)). An organization has standing “when its members would otherwise have
    standing to sue in their own right, the interests at stake are germane to the
    organization’s purpose, and neither the claim asserted nor the relief requested
    requires the participation of individual members in the lawsuit.” Friends of the
    Earth, Inc. v. Laidlaw Env’t Servs. (TOC), Inc., 
    528 U.S. 167
    , 181 (2000).
    In cases where “the plaintiff is not himself the object of the government action
    or inaction he challenges, standing is not precluded, but it is ordinarily substantially
    20

    504 U.S. at 562
     (quotations omitted).
    But “[a]s a general rule, . . . environmental plaintiffs adequately allege [an] injury in
    fact when they aver that they use the affected area and are persons for whom the
    aesthetic and recreational values of the area will be lessened by the challenged
    activity.” S. Utah Wilderness All. v. Palma, 
    707 F.3d 1143
    , 1155 (10th Cir. 2013)
    (quotations omitted).
    When the plaintiff alleges a procedural injury, it satisfies the Article III
    requirement when “the procedures in question are designed to protect some
    threatened concrete interest of the party that is the ultimate basis of its standing.”
    New Mexico v. Dep’t of Interior, 
    854 F.3d 1207
    , 1215 (10th Cir. 2017) (alterations
    omitted).
    Second, the plaintiff must show that its injury is “fairly traceable to the
    challenged action.” Friends of the Earth, 
    528 U.S. at 180
    . “Article III does at least
    require proof of a substantial likelihood that the defendant’s conduct caused
    plaintiff’s injury in fact.” Nova Health Sys. v. Gandy, 
    416 F.3d 1149
    , 1156 (10th Cir.
    2005). “[P]laintiffs bear the burden of pleading and proving concrete facts showing
    that the defendant’s actual action has caused the substantial risk of harm.” Clapper,
    
    568 U.S. at
    414 n.5 (emphasis added).
    Third, the plaintiff must show that the injury is redressable—that it is “‘likely,’
    as opposed to merely ‘speculative,’ that the injury will be ‘redressed by a favorable
    decision.’” Defs. of Wildlife, 
    504 U.S. at 561
     (quoting Simon v. E. Ky. Welfare
    Rights Org., 
    426 U.S. 26
    , 38, 43 (1976)). “A showing that the relief requested might

    redress the plaintiff’s injury is generally insufficient to satisfy the redressability
    requirement.” WildEarth Guardians v. Pub. Serv. Co. of Colo., 
    690 F.3d 1174
    , 1182
    (10th Cir. 2012). When the plaintiff alleges a procedural injury, “[t]he person who
    has been accorded a procedural right to protect his concrete interests can assert that
    right without meeting all the normal standards of redressability and immediacy.”
    Defs. of Wildlife, 
    504 U.S. at
    572 n.7; see also WildEarth Guardians, 690 F.3d
    at 1182.
    NEPA Standing
    At the district court and initially on appeal, the Service did not challenge the
    Center’s standing to bring its NEPA claims. Following oral argument, we sua sponte
    ordered the parties to address the Center’s standing as to these claims. In the
    supplemental briefs, the Center argues it has standing, and the Service now argues it
    does not.
    At the district court, the Center submitted multiple declarations from its
    organizational members identifying their affected interests. See App. at 134-37
    (declaration of Susan Elofson-Hurst), id. at 138-41 (declaration of Jon Lipsky); id. at
    241-43 (declaration of Bonnie Graham-Reed), id. at 1284-87 (declaration of LeRoy
    Moore), id. at 780-82 (declaration of Elizabeth Panzer). At the preliminary
    injunction hearing, the Center also elicited testimony from its members pertinent to
    standing. Id. at 1181-85 (testimony of Elizabeth Panzer), id. at 1186-94 (testimony
    of Jon Lipsky).
    22
    Appellate Case: 21-1310        Document: 010110713092      Date Filed: 07/19/2022    Page: 23
    Injury in fact
    The Center has shown it suffered an injury in fact through Mr. Lipsky’s
    declaration and his testimony at the preliminary injunction hearing.17 In his
    declaration, Mr. Lipsky averred that he “conduct[s] business in the immediate area of
    the [Refuge],” “visit[s] just outside the perimeter of the [Refuge] . . . about once per
    month,” and “plan[s] to continue this schedule in the future.” App. at 141. Mr.
    Lipsky stated that he reviewed the trail maps the Service provided in the 2018 EAS
    and determined that “[t]he Trails depicted . . . are significantly different than those
    previously approved for the Refuge.” Id. at 139. He noted that “[t]he new final map
    includes a trail entering the east side of the Refuge” in the Wind Blown Area. Id. He
    also noted the creation of “[t]rails on the newly acquired ‘Section 16’ [Parcel,] . . .
    which was not officially part of the federal property considered ‘Rocky Flats,’” so
    “there has been no study of the impact to this property of [the Service’s] decision to
    route the [t]rails through it.” Id. at 139-40. Thus, “[t]he construction and operation
    of the [Refuge] poses a health risk to [him].” Id. at 141.
    At the preliminary injunction hearing, Mr. Lipsky testified that construction
    and use of the trails in the Refuge, including the “new configuration into Section 16,”
    would kick up more dust that could be radioactive. Id. at 966.
    Mr. Lipsky has demonstrated an injury in fact. As we explained in Dine
    Citizens Against Ruining Our Environment v. Bernhardt, Mr. Lipsky must show that
    17
    Mr. Lipsky is a member of the Center. App. at 138.
    23
    Appellate Case: 21-1310     Document: 010110713092         Date Filed: 07/19/2022   Page: 24
    the Service’s failure to comply with NEPA (1) “created an increased risk of actual,
    threatened, or imminent environmental harm;” and (2) “the increased risk of
    environmental harm injures [his] concrete interests by demonstrating either [his]
    geographical nexus to, or actual use of the site of the agency action.” 
    923 F.3d 836
    ,
    840 (10th Cir. 2019) (quotations omitted). Mr. Lipsky did so by identifying the trail
    modifications made in the 2018 EAS and explaining how they may cause him
    increased injury.18
    Dine Citizens is further instructive. There, the agency issued an EIS in 2003 to
    allow almost 10,000 gas and oil wells to be drilled on federally managed lands in
    New Mexico. 
    Id. at 836
    . The EIS “did not discuss specific sites or approve any
    individual wells,” but it anticipated that most of the wells would be drilled in the
    northern parts of the managed area. 
    Id.
     (quotations omitted). After issuance of the
    EIS, operators applied for drilling permits, which prompted the agency to issue an
    EA evaluating the proposed drilling. 
    Id. at 837
    . The plaintiffs, concerned
    environmental groups, sued in 2015 challenging the agency’s decision to issue
    permits for hundreds of oil and gas wells. 
    Id. at 838
    .
    18
    As we discuss in the merits section below, the potential trail expansion into
    the Wind Blown Area is not part of the 2018 EAS, and the Service properly
    segmented it from its analysis. But for the purposes of standing, we do not decide the
    merits of the Center’s NEPA claims. See Dine Citizens, 923 F.3d at 841 (“Whether
    th[e] environmental harm is of a manner or to a degree not already considered . . . is a
    question that goes to the merits of Appellants’ NEPA claim. Appellants, of course,
    need not prove the merits of their claim in order to establish standing.”).
    24
    Appellate Case: 21-1310          Document: 010110713092    Date Filed: 07/19/2022    Page: 25
    We held the plaintiffs had alleged an injury in fact. Id. at 840-41. Because
    they “submitted affidavits that show an increase in environmental harm from drilling
    activities,” they adequately alleged that “the agency created an increased risk of
    actual, threatened, or imminent environmental harm” by skipping NEPA procedures
    when it authorized the new drilling sites. Id. (emphasis added). We also concluded
    that the plaintiffs proved their concrete interests by presenting affidavits showing that
    they regularly visited near the well sites and thus established a “geographic nexus to
    . . . the site.” Id. at 841.
    Like the affidavits in Dine Citizens, Mr. Lipsky’s declaration and testimony
    alleged that the changes to the trails would cause an increased risk of radioactive dust
    exposure. And because he alleged that he regularly visits near the Refuge, he has
    shown a concrete interest in this increased exposure. He has thus alleged an injury in
    fact.19
    19
    In contrast, the other declarations and testimony likely fall short of
    establishing an injury in fact. None alleged that the trail modifications in the 2018
    EAS would cause an increase in environmental harm. Instead, they generally
    opposed construction of trails in the Refuge—a decision made in the 2004 CCP/EIS
    and the 2005 ROD, not the 2018 EAS. See App. at 136 (“If construction on the
    Refuge were to proceed . . . the plutonium and other hazardous substances present on
    the Refuge and disturbed by the construction would harm me . . . .”), id. at 242-43
    (same), id. at 781 (“My family’s health will be put at even greater risk by allowing
    the [Service] . . . to begin construction on the Refuge . . . .”), id. at 1184 (“Even if I
    didn’t want to go to the refuge, if it was open, I can’t keep . . . microscopic particles
    of possible contaminants out of my house if my neighbors bring them into the
    neighborhood.”).
    But since “the presence of one party with standing is sufficient to satisfy
    Article III’s case-or-controversy requirement,” we may proceed to the merits without
    determining the other members’ standing. Rumsfeld v. Forum for Acad. & Inst. Rts.,
    Inc., 
    547 U.S. 47
    , 52 n.2 (2006); see also Campbell v. Buckley, 
    203 F.3d 738
    , 740 n.1
    25
    Appellate Case: 21-1310      Document: 010110713092        Date Filed: 07/19/2022     Page: 26
    Traceability
    The Center has also shown that its NEPA injury is fairly traceable to the
    challenged agency action. “In the context of a NEPA claim, the injury is the
    increased risk of environmental harm to concrete interests.” Dine Citizens, 923 F.3d
    at 843-44 (quotations and alterations omitted). Here, through Mr. Lipsky, the Center
    has alleged that the Service’s failure to comply with NEPA when it modified the
    trails has increased the risk that the Center’s interests will be harmed. Id. at 844
    (“Appellants have alleged that the [agency] did not comply with NEPA in granting
    the challenged [permits], and that its alleged failure resulted in the agency’s
    uninformed decisionmaking as to these additional wells. This is sufficient to
    establish causation.” (quotations omitted)). It has thus shown causation.
    Redressability
    Finally, the Center has shown that its injury is redressable. When a plaintiff
    alleges a procedural violation, we relax the redressability requirements. Defs. of
    Wildlife, 
    504 U.S. at
    572 n.7. In this context, “a plaintiff need not establish that the
    ultimate agency decision would change upon [NEPA] compliance.” Comm. to Save
    the Rio Hondo v. Lucero, 
    102 F.3d 445
    , 452 (10th Cir. 1996). The plaintiff must
    show only “that its injury would be redressed by a favorable decision requiring
    (10th Cir. 2000) (“Because the individual plaintiffs . . . have standing, and because
    . . . [they] jointly raise the same substantive arguments on appeal, . . . there is no need
    to address the standing of the [other] plaintiffs.” (citing Bowsher v. Synar, 
    478 U.S. 714
    , 721 (1986) (alterations omitted)).
    26
    Appellate Case: 21-1310      Document: 010110713092       Date Filed: 07/19/2022      Page: 27
    compliance with NEPA procedures.” Dine Citizens, 923 F.3d at 844 (quotations
    omitted). The Center has done so here. It alleges that the Service failed to comply
    with NEPA, and a favorable decision would compel the Service to meet its NEPA
    obligations. The Center has thus shown its injury is redressable.
    *   *    *    *
    In sum, the Center has done enough to establish standing to bring its NEPA
    claims. We repeat, however, that many of the Center’s standing arguments hinge on
    the opening of the Refuge, which is not the agency action before us. But the Center
    is correct that we cannot conflate our standing inquiry with analysis of the merits of
    its NEPA claims. We address the merits below.
    ESA Standing
    The Center challenges the district court’s dismissal of its ESA claim for lack
    of standing. For standing, the Center relies on Randal Stafford’s interest20 in the
    Preble’s meadow jumping mouse, an endangered species that resides on the Refuge.
    His interest is insufficient to confer standing.
    The Center attached Mr. Stafford’s declaration to its motion for a preliminary
    injunction. In it, Mr. Stafford stated that he has “a personal interest in the protection
    and conservation of . . . the threatened Preble’s Meadow Jumping Mouse.” App.
    at 110. He averred that he “derive[s] great aesthetic, spiritual and recreational
    benefits from looking for and seeing such species, studying them, enjoying their
    20
    Mr. Stafford is a member of the Center. App. at 109.
    27
    Appellate Case: 21-1310      Document: 010110713092         Date Filed: 07/19/2022     Page: 28
    presence in their natural environment and knowing that the provisions of the [ESA]
    are protecting and conserving the Jumping Mouse and its Critical Habitat in the
    Refuge.” Id.
    During the preliminary injunction hearing, Mr. Stafford testified that he had
    never visited the Refuge but had visited friends who lived nearby and biked around
    its boundaries. Id. at 1196. He clarified he was interested in the Preble’s mouse as a
    source of food for birds that he enjoyed watching. Id. at 1197. He expressed concern
    that “[i]f the refuge is opened to the public, I think there is a possibility that the
    construction and use of the trails and grounds of the refuge will result in the
    disruption of the habitat and reproduction of” the Preble’s mouse, which in turn
    would have a detrimental impact on the birds who prey upon it. Id. at 1198.
    Although he said he would “find [it] interesting” to see the Preble’s mouse jump, he
    conceded he had never looked for, seen, or seriously studied the Preble’s mouse. Id.
    at 1201-02. He also admitted he “probably would not visit [the Refuge] just to see
    the Preble’s . . . mouse.” Id. at 1204.
    We doubt the Center has alleged an injury in fact based on Mr. Stafford’s
    interests. But rather than decide that issue, we deny standing for failure to show the
    alleged injury is fairly traceable to the challenged agency action—the trail
    modifications approved in the 2018 EAS. Mr. Stafford’s declaration and
    accompanying testimony show his purported injury stems from the construction of
    any trail, not the trail modifications made in the 2018 EAS. Id. at 110 (“The
    construction . . . of multipurpose trails and the paved Rocky Mountain Greenway
    28

    [trail] in the Refuge would irreparab[ly] harm my interests in the . . . Preble’s
    Meadow Jumping Mouse . . . .”); id. at 1198 (“If the refuge is opened to the public,
    I think there is a possibility that the construction and use of the trails . . . will result
    in disruption of the [Preble’s mouse’s] habitat . . . .”).
    The decision to construct trails in the Refuge was made in the 2004 CCP/EIS
    and 2005 ROD. The Center cannot now challenge that decision. For ESA standing,
    it must link Mr. Stafford’s injury to the trail modifications made in the 2018 EAS. It
    has failed to allege any link between the 2018 trail modifications and a detrimental
    impact on the Preble’s mouse or its habitat. The Center has thus failed to meet the
    second element of standing, so we affirm dismissal of its ESA claim.
    B. NEPA Claims
    Because the Center has standing to bring its NEPA claims, we turn to the
    merits. “We review de novo a district court’s decision in an APA case.” Biodiversity
    Conservation All., 762 F.3d at 1059.
    The Center argues the Service violated NEPA by (1) segmenting the proposed
    trail modification into the Wind Blown Area from the 2018 EAS’s analysis,
    (2) relying on the categorical exclusions to avoid conducting an EA, and (3) failing to
    prepare a supplemental EIS based on significant new circumstances.
    We will set aside an agency action if it is “arbitrary, capricious, an abuse of
    discretion, or otherwise not in accordance with law.” 
    5 U.S.C. § 706
    (2)(A). An
    agency action is arbitrary and capricious if the agency “entirely failed to consider an
    important aspect of the problem, offered an explanation for its decision that runs

    and a court is not to substitute its judgment for that of the agency.”

    , 1045 (10th Cir. 2011) (citations omitted). Our deference “is

    matters within the agency’s area of expertise.” Russell, 
    518 F.3d at 824
     (quotations
    omitted). With these principles in mind, we turn to the Center’s arguments.
    Segmentation
    The Center argues the Service was not permitted to exclude the proposed trail
    extension and access point in the Wind Blown Area from the 2018 EAS. It contends
    this potential modification was so intrinsically linked to the modifications made in
    the 2018 EAS that the Service had to evaluate the Wind Blown Area proposals in the
    same assessment. We disagree.
    Under NEPA, an agency must consider “[c]onnected actions,” “[c]umulative
    actions,” and “[s]imilar actions” in the “same impact statement.” 
    40 C.F.R. § 1508.25
    (a)(1)-(3). This regulation “prevent[s] agencies from minimizing the
    potential environmental consequences of a proposed action (and thus short-circuiting
    NEPA review) by segmenting or isolating an individual action that, by itself, may not

    have a significant environmental impact.” Citizens’ Comm. to Save Our Canyons v.
    U.S. Forest Serv., 
    297 F.3d 1012
    , 1028 (10th Cir. 2002).
    To determine whether two actions are connected, we apply the independent-
    utility test.21 Under that test, “two proposed actions [are] connected where one action
    could not occur but for the occurrence of the other.” 
    Id. at 1029
    . On the other hand,
    “projects that have independent utility are not connected actions.” 
    Id.
     (quotations
    omitted).
    The trail modifications in the 2018 EAS have independent utility and do not
    depend on the potential modifications in the Wind Blown Area. The modifications
    made to the Rocky Mountain Greenway trail remain viable even if the Service never
    proceeds with expansion of the trail into the Wind Blown Area or creates an access
    point there. Nor does the Service’s stated goal of trail interconnectedness undermine
    the independent utility of the modifications to the Rocky Mountain Greenway trail.
    As the Service notes, even without the proposed expansion into the Wind Blown
    Area, trail users would still have access to an “out-and-back” trail. Trail users can
    enter the Refuge from the northern entrance and access the Rocky Mountain
    21
    The applicable regulations state that a proposed action is connected to other
    actions if the proposed action (1) “[a]utomatically trigger[s] other actions which may
    require [EISs], (2) “[c]annot or will not proceed unless other actions are taken
    previously or simultaneously,” or (3) is an “interdependent part[] of a larger action
    and depend[s] on the larger action for [its] justification.” 
    40 C.F.R. § 1508.25
    (a)(1).
    In Citizens’ Committee to Save Our Canyons, we followed other circuits and held that
    proposed actions are not closely related—and therefore do not require concurrent
    analysis under 
    40 C.F.R. § 1508.25
    —if they have independent utility. 
    297 F.3d at 1029
    .

    Appellate Case: 21-1310    Document: 010110713092         Date Filed: 07/19/2022    Page: 32
    Greenway trail from there. The trail travels southwest first, taking visitors to the
    historic caprock mine in the Section 16 Parcel. It then continues eastward, and users
    can connect to the East Woman Creek Loop trail, which itself provides two points of
    departure from the Refuge. Indeed, the Service has opened the Refuge’s trails for
    public use without the trail expansion into the Wind Blown Area.22 Oral Arg. at
    18:40-19:03. The modifications therefore have independent utility, and it was not
    arbitrary or capricious for the Service to segment the potential changes in the Wind
    Blown Area from its analysis.23
    22
    The Service has not committed to expanding the Rocky Mountain Greenway
    trail into the Wind Blown Area or to creating an access point there. By mentioning
    the potential changes in the 2018 EAS, the Service has alerted the Center and other
    concerned parties that such an action may take place later. See 
    40 C.F.R. § 1501.2
    (“Agencies shall integrate the NEPA process . . . at the earliest possible time to
    insure that planning and decisions reflect environmental values . . . and to head off
    potential conflicts.”). At oral argument, the Service confirmed that it has yet to make
    any determination on whether to proceed with those proposals. See Oral Arg. at
    18:57-19:03.
    23
    For the same reasons, the potential changes in the Wind Blown Area are not
    cumulative. Actions have cumulative impact when they are “so interdependent that it
    would be unwise or irrational to complete one without the others.” Airport
    Neighbors All., Inc. v. United States, 
    90 F.3d 426
    , 430 (10th Cir. 1996) (quotations
    omitted); see Utahns for Better Transp. v. U.S. Dep’t of Transp., 
    305 F.3d 1152
    ,
    1173 (10th Cir. 2002). The Center offers nothing to show that the trail modifications
    in the 2018 EAS are “unwise or irrational” should the Service never proceed with the
    potential modifications in the Wind Blown Area.
    To the extent the Center argues the potential changes in the Wind Blown Area
    are similar to the proposed trail modifications and thus should have been analyzed
    concurrently in the 2018 EAS, it has waived this argument through inadequate
    briefing. See Burke v. Regalado, 
    935 F.3d 960
    , 1014 (10th Cir. 2019). In its opening
    brief, the Center quoted the applicable regulation but failed to develop any argument
    in support. Aplt. Br. at 22-23.
    32

    Categorical Exclusions and Extraordinary Circumstances
    The Service relied on three categorical exclusions for the trail modifications to
    avoid having to perform an EA. It determined the action consisted of:
    1) “minor changes in the amounts or types of public use
    on Service or State-managed lands, in accordance with
    existing regulations, management plans, and
    procedures;”
    2) “minor changes in existing master plans,
    comprehensive conservation plans, or operations, when
    no or minor effects are anticipated;” and
    3) “the issuance of new or revised site, unit, or activity-
    specific management plans for public use, land use, or
    other management activities when only minor changes
    are planned.”
    AR 9 (citing 516 DM § 8.5(B)(7), (9)-(10)). It also concluded no extraordinary
    circumstances rendered the 2018 EAS ineligible for the categorical exclusions.
    The Center does not challenge the categorical exclusions. Instead, it argues
    that two extraordinary circumstances foreclosed the use of the categorical exclusions:
    (a) the impact on public health, and (b) the highly controversial nature of the project.
    We address each in turn.
    The impact on public health or safety
    The Center argues the trail modifications’ impact on public health presented
    extraordinary circumstances. See 
    43 C.F.R. § 46.215
    (a) (extraordinary circumstance
    exists if the action may “[h]ave significant impacts on public health or safety”). Its
    arguments are not convincing.
    33
    Appellate Case: 21-1310    Document: 010110713092        Date Filed: 07/19/2022   Page: 34
    First, the Center points to elevated plutonium levels in the Wind Blown Area.
    It contends that because the Service has previously conceded that the Wind Blown
    Area has elevated plutonium levels, the trail modifications constitute an
    extraordinary circumstance. But as discussed above, any potentially elevated
    plutonium levels in the Wind Blown Area are not relevant. The potential trail
    modification into the Wind Blown Area is not part of the challenged agency action
    because the Service excluded it from the 2018 EAS. The Center thus cannot use
    potentially elevated risks in the Wind Blown Area to establish that the 2018 EAS’s
    trail modifications may have a significant impact on public health.
    Second, the Center argues the Service has previously acknowledged that
    different parts of the Refuge have varying levels of plutonium radiation. As a result,
    the modified trails could end up in a higher radiation area, which could harm public
    health. This argument fails. The 2004 CCP/EIS considered the varying plutonium
    levels across the Refuge and determined that the Refuge was generally safe for public
    use. The Center has failed to show why the trail modifications approved by the 2018
    EAS present an added risk to public health on this ground.24
    24
    As we discuss below, to the extent the Center bases its concern on the trail
    modification that cuts into the Section 16 Parcel, it ignores that the Service made the
    decision to incorporate the parcel into the Refuge in 2011, when the Service prepared
    an EA and issued a FONSI. The Service based its determination in part on soil
    sampling taken on the border of the parcel and the Refuge, finding that the plutonium
    levels there were sufficiently low to allow for the acquisition.
    34
    Appellate Case: 21-1310    Document: 010110713092        Date Filed: 07/19/2022    Page: 35
    The highly controversial nature of the action
    The Center also argues that the 2018 EAS trail modifications are highly
    controversial, precluding the Service’s use of the categorical exclusions. See
    
    43 C.F.R. § 46.215
    (c) (extraordinary circumstance exists if the action may “[h]ave
    highly controversial environmental effects”). This argument fails to link the
    controversy to the challenged agency action.
    First, the Center relies on the controversy surrounding the opening of the
    Refuge for public use. Aplt. Br. at 33-35. But that controversy did not arise because
    of the 2018 EAS trail modifications. The 2004 CCP/EIS addressed public opposition
    to the opening of the Refuge. The Service conducted an extensive environmental
    analysis and decided to proceed with the opening. The Center cannot use the original
    controversy in 2004 to establish an extraordinary circumstance now. To conclude
    otherwise would prohibit the Service from using categorical exclusions for actions
    related to the Refuge and would undermine the purpose of these exclusions. See
    Utah Env’t Cong. v. Bosworth, 
    443 F.3d 732
    , 742 (10th Cir. 2006) (“By relying on
    categorical exclusions, the Forest Service promotes efficiency in its NEPA review
    process while avoiding unnecessary analysis.”). The Center therefore cannot use the
    controversy surrounding the initial decision to open the Refuge to prove that the trail
    modifications are highly controversial.
    Second, the Center argues for the first time on appeal that the 2018 EAS is
    highly controversial because it proposed placing an access point in the Wind Blown
    35
    Appellate Case: 21-1310      Document: 010110713092      Date Filed: 07/19/2022     Page: 36
    Area. It argues this decision is highly controversial because the Service discussed
    placement of the access point with affected municipalities.
    The Center has waived this argument because it failed to present it to the
    district court and has not argued plain error here. See Little v. Budd Co., Inc., 
    955 F.3d 816
    , 821 (10th Cir. 2020). “[W]e may not reverse the district court’s judgment
    in this case based on theories coined for the first time only on appeal unless [the
    Center] makes a showing of plain error—something [it] has not even attempted.”
    Scherer v. U.S. Forest Serv., 
    653 F.3d 1241
    , 1245 (10th Cir. 2011). Even assuming it
    did not waive this argument, and even assuming the discussions with the
    municipalities are sufficient to render the action highly controversial, the Center’s
    argument still fails. As discussed above, the 2018 EAS did not determine the access
    point in the Wind Blown Area and reserved this decision for the future. It
    acknowledged that this issue would require an additional NEPA determination. The
    Center cannot use a potential controversy surrounding a future decision to prove that
    the agency action challenged here is highly controversial. The Center thus has not
    shown that the 2018 EAS is highly controversial.
    *    *    *    *
    The Service relied on categorical exclusions to make the trail modifications in
    the 2018 EAS. It did so after concluding no extraordinary circumstances existed that
    would prohibit the use of these exclusions. The Center has failed to show that the
    Service’s reliance on the categorical exclusions to make the trail modifications was
    arbitrary or capricious.
    36
    Appellate Case: 21-1310     Document: 010110713092        Date Filed: 07/19/2022    Page: 37
    Supplemental EIS
    The Center argues the Service needed to prepare a supplemental EIS because
    its acquisition of the Section 16 Parcel and ensuing decision to build a trail on the
    parcel presented a significant new circumstance.
    “An agency must prepare a supplemental assignment if the agency makes
    substantial changes in the proposed action that are relevant to environmental
    concerns.” New Mexico ex rel. Richardson v. Bureau of Land Mgmt., 
    565 F.3d 683
    ,
    705 (10th Cir. 2009) (quotations and alterations omitted). But “an agency need not
    supplement an EIS every time new information comes to light after the EIS is
    finalized.” Marsh v. Or. Nat. Res. Council, 
    490 U.S. 360
    , 373 (1989). “To require
    otherwise would render agency decisionmaking intractable, always awaiting updated
    information only to find the new information outdated by the time a decision is
    made.” 
    Id.
     Thus, “[w]hen the relevant environmental impacts have already been
    considered earlier in the NEPA process, no supplement is required.” New Mexico ex
    rel. Richardson, 
    565 F.3d at 705
     (quotations omitted).
    In determining whether a supplemental EIS is required, we apply the rule of
    reason, which “turns on the value of the new information to the still pending
    decisionmaking process.” Marsh, 
    490 U.S. at 374
    . “If there remains major Federal
    action to occur, and if the new information is sufficient to show that the remaining
    action will affect the quality of the human environment in a significant manner or to
    a significant extent not already considered, a supplemental EIS must be prepared.”
    
    Id.
     (quotations and alterations omitted).
    37
    Appellate Case: 21-1310     Document: 010110713092         Date Filed: 07/19/2022    Page: 38
    Neither the acquisition of the Section 16 Parcel nor the decision to extend a
    trail onto it amounted to a significant new circumstance requiring a supplemental
    EIS. As to the acquisition of the Section 16 Parcel, the Service evaluated that issue
    in 2011. The acquisition is not the challenged agency action here. As to the one-
    mile trail extension into the Parcel, which is part of the challenged agency action
    here, the Center fails to explain how the modification of a trail that cuts into the
    Section 16 Parcel is a significant new circumstance. The Service thus did not act
    arbitrarily and capriciously when it did not prepare a supplemental EIS regarding
    extension of a trail into the Section 16 Parcel.25
    *    *    *     *
    In sum, the Service did not act arbitrarily or capriciously in (1) segmenting the
    Wind Blown Area potential proposals from its analysis, (2) concluding no
    25
    Even assuming the Service’s acquisition of the Section 16 Parcel was the
    challenged agency action, the Center has failed to show it was a significant change in
    circumstances. When the Service acquired the parcel, it conducted an EA and issued
    a FONSI. It did so after it “found no known or observable environmental
    contaminant[] issues related to the parcel.” AR 1038. The Service reached this
    conclusion based in part on “[a] survey of Refuge lands conducted by the Department
    of Energy and the [Service] in 2006” that included 41 soil samples across the Refuge,
    only three of which contained plutonium levels above 1 pCi/g. AR 1047.
    The Service acknowledged that these samples “did not address Section 16” and
    “soil samples were collected adjacent to the northern and eastern property boundaries
    [of Section 16]. [But] [e]ach of these samples yielded actinide concentrations well
    below 1 pCi/g.” 
    Id.
     Thus, an area closer to the Industrial Area than the Section 16
    Parcel had plutonium radiation levels well below the 50 pCi/g threshold.
    The Center fails to point to any evidence undermining the 2011 FONSI. The
    Center cites testimony it presented at the preliminary injunction hearing regarding a
    photograph of a barrel that the Service included in the 2011 FONSI. We address this
    testimony below.
    38
    Appellate Case: 21-1310     Document: 010110713092       Date Filed: 07/19/2022      Page: 39
    extraordinary circumstances existed, or (3) determining that no significant new
    circumstances compelled a supplemental EIS.
    C. Supplemental and Extra-Record Documents
    Finally, the Center argues the district court should have (1) supplemented the
    administrative record with evidence that the Service improperly excluded, and (2)
    considered extra-record evidence that allegedly would undermine the Service’s
    analysis in the 2018 EAS.
    “We review a district court’s determination of whether or not to exclude extra-
    record evidence for abuse of discretion.” Citizens for Alts. to Radioactive Dumping
    v. U.S. Dep’t of Energy, 
    485 F.3d 1091
    , 1096 (10th Cir. 2007). We apply the same
    standard to a district court’s refusal to supplement the administrative record. See Am.
    Wildlands v. Kempthorne, 
    530 F.3d 991
    , 1002 (D.C. Cir. 2008).
    When a court evaluates whether an agency has complied with the APA, its
    review “is generally based on the full administrative record that was before all
    decision makers.” Bar MK Ranches v. Yuetter, 
    994 F.2d 735
    , 739 (10th Cir. 1993).
    “The complete administrative record consists of all documents and materials directly
    or indirectly considered by the agency.” 
    Id.
     “[T]he designation of the
    Administrative Record, like any established administrative procedure, is entitled to a
    presumption of administrative regularity.” 
    Id. at 740
    . We must therefore “assume[]
    the agency properly designated the Administrative Record absent clear evidence to
    the contrary.” 
    Id.
    39
    Appellate Case: 21-1310    Document: 010110713092        Date Filed: 07/19/2022      Page: 40
    In “extremely limited” circumstances, a court may supplement the
    administrative record or consider extra-record evidence. Am. Mining Cong. v.
    Thomas, 
    772 F.2d 617
    , 626 (10th Cir. 1985). Known as the American Mining
    Congress exceptions, they include when (1) “the record is deficient because the
    agency ignored relevant factors it should have considered,” (2) “the agency
    considered factors that were left out of the formal record,” and (3) “evidence coming
    into existence after the agency acted demonstrates that the actions were right or
    wrong.” 
    Id.
     The Center fails to show the district court abused its discretion in
    determining that the evidence at issue here falls outside these exceptions.
    Supplementation of the Administrative Record
    We first address the four documents that the Center argues the Service
    excluded from the administrative record and the district court refused to add.
    First, the Center argues the district court should have added the 2012 Kaltofen
    Study to the administrative record because it showed elevated plutonium levels in the
    Refuge. The 2012 Kaltofen Study assessed the dispersion of plutonium from the
    Industrial Area (in the Refuge’s center) to the eastern part of the Refuge and beyond.
    But, as previously discussed, the 2018 EAS did not make any changes to the eastern
    part of the Refuge. At most, the Service stated that it might make trail modifications
    in the Wind Blown Area, but it reserved this decision for a future NEPA
    40
    Appellate Case: 21-1310    Document: 010110713092       Date Filed: 07/19/2022       Page: 41
    determination. The 2012 Kaltofen Study is thus not relevant to the trail
    modifications made in the 2018 EAS.26
    Second, the Center contends that the Service improperly excluded the Cook
    jury verdict form from the administrative record. As with the 2012 Kaltofen Study,
    the Cook jury verdict form concerned plutonium levels to the east of the Industrial
    Area.27 It thus had no bearing on the Service’s 2018 decision to make trail
    modifications on the western part of the Refuge.
    Third, the Center argues the 2011 email chain between Service officials
    discussing trail modifications should have been part of the administrative record.
    The 2011 email chain mentioned a possible trail alteration that would put one trail
    near the plutonium plume area in the eastern portion of the Refuge. The Center fails
    to explain how the emails concern the trail modifications made in the 2018 EAS. The
    2018 EAS did not address changes to the trail routes in the plutonium plume area.
    Without more, the Center cannot show the district court abused its discretion in
    declining to add the 2011 email chain to the administrative record.
    26
    Even assuming the 2012 Kaltofen Study was relevant to the agency action
    here, its findings of residual plutonium exposure are not inconsistent with the
    Service’s findings in the 2004 CCP/EIS. As the Service notes, the 2012 Kaltofen
    Study determined that there were plutonium levels up to 1,579 pCi/Kg, App. at 112,
    but that translates to 1.5 pCi/g—well below the 50 pCi/g the Service set as the
    maximum allowed in the Refuge. AR 5592.
    27
    The Cook jury verdict form stemmed from a 2006 civil trial against
    Rockwell International Company and Dow Chemical Company. The jury found the
    defendants liable for trespass by exposing the plaintiffs’ properties, which were
    located east of the Refuge, to plutonium.
    41

    Fourth, the Center argues the district court should have added the 2018
    Nichols declaration to the administrative record. This declaration discussed testing
    on the site in the 1970s that showed elevated radiation levels. The Center prepared
    this declaration in support of its motion for a preliminary injunction. It fails to
    explain why a declaration prepared for litigation challenging an agency action should
    be part of the administrative record. The district court did not abuse its discretion in
    declining to add it.28
    Extra-Record Evidence
    The Center also argues the district court abused its discretion in declining to
    consider evidence that was not part of the administrative record. On rare occasions, a
    court may consider “evidence coming into existence after the agency acted [that]
    demonstrates that the actions were right or wrong.” Am. Mining Cong., 
    772 F.2d at 626
    . The Center argues the district court abused its discretion by failing to do so
    here.
    First, the Center argues the district court should have weighed the testimony
    from the witnesses it presented during the preliminary injunction hearing.29 But
    28
    The 2018 Nichols declaration may be more accurately characterized as
    extra-record material. If it were, our analysis above would not change.
    29
    The Center solicited testimony from (1) John Barton, a former employee at
    the Rocky Flats plant; (2) Mr. Nichols, a scientist who performed plutonium testing
    in the Refuge during the 1970s; (3) Michael Ketterer, a former EPA official who
    tested for plutonium on the eastern part of the Refuge; and (4) Mr. Lipsky, a former
    FBI officer who was involved in a criminal investigation of the Rocky Flats plan in
    the late 1980s and early 1990s.
    42
    Appellate Case: 21-1310      Document: 010110713092       Date Filed: 07/19/2022        Page: 43
    much of the testimony the Center solicited was speculative, and the district court was
    within its discretion to decline to consider it. For instance, the Center points to
    testimony from two witnesses, including Mr. Lipsky, about the photograph of the
    barrel located in the Section 16 Parcel. They claimed the barrel originated from the
    Industrial Area. But they conceded that they did not inspect the barrel and that they
    based their suspicions solely on the photograph. App. at 921, 926-27, 969.
    The other testimony fares no better. Some witnesses focused on plutonium
    levels in the eastern part of the Refuge. Id. at 954. Others discussed testing that
    occurred in the 1970s. Id. 931-48. This testimony lacks any nexus to the challenged
    agency action—the modification of the trails. And as discussed above, the 2018 EAS
    made no trail modifications on the eastern part of the Refuge. And the testimony
    regarding 1970s testing appears to be a renewed challenge to the Service’s 2005
    ROD opening the Refuge for public use. The district court did not abuse its
    discretion in declining to consider this testimony.
    Second, the Center argues the district court should have considered a 2019
    memorandum from the Broomfield City Council30 noting that the Service was
    relocating prairie dogs into the Refuge. The Center contends the prairie dogs would
    disturb and expose contaminated Refuge soil. This memorandum is speculative and
    lacks any connection to the challenged agency action. The Center fails to link the
    reintroduction of prairie dogs to the trail modifications. At most, this document
    30
    Broomfield City is located just outside the Refuge’s eastern boundary.
    43
    Appellate Case: 21-1310     Document: 010110713092        Date Filed: 07/19/2022     Page: 44
    could relate to the Service’s decision in 2005 to open the Refuge for public use, but
    that is not the agency action before us. We therefore see no abuse of discretion.
    Third, the Center argues the district court should have considered soil
    sampling taken in 2019 to the east of the Refuge showing plutonium levels that
    exceeded the limit the EPA set. Even if this sampling may be relevant to potential
    trail modifications in the eastern part of the Refuge, it has no bearing on the
    challenged agency action. Again, the Service made no changes to trails on the
    eastern part of the Refuge in the 2018 EAS. The district court did not abuse its
    discretion.
    III. CONCLUSION
    We affirm.
