    MEMORANDUM OPINION
    This case is nominally a procedural action that Plaintiffs Nucor Steel-Arkansas
    and Nucor-Yamato Steel Company (collectively, “Nucor”) have filed against the
    Administrator of the Environmental Protection Agency (“EPA”) pursuant to one of the
    citizen-suit provisions of the Clean Air Act (“CAA”), 42 U.S.C. §§ 7401–7671q. See
    
    id. § 7604(a)(2)
    (authorizing lawsuits against the Administrator of the EPA where the
    agency has allegedly failed to perform a non-discretionary duty). But in the broader
    scheme of things, this matter is actually one of many battlegrounds in a multi-front
    conflict between two competing steel-manufacturing companies with facilities in
    Mississippi County, Arkansas. Nucor operates two manufacturing facilities near
    Blytheville, Arkansas, which is approximately twenty miles from a site in Osceola,
    Arkansas, at which Big River Steel Company (“Big River Steel”) has proposed to build
    a new manufacturing facility. (See Nucor’s Second Suppl. & Am. Compl. (“Compl.”),
    ECF No. 40, ¶¶ 4–5, 10.) 1 Big River Steel obtained a permit from the Arkansas
    Department of Environmental Quality (“ADEQ”) that authorized the construction and
    operation of its planned facility, and Nucor responded by launching legal attacks
    against the permit, both in the Arkansas state court system and in the U.S. District
    Court for the Eastern District of Arkansas. See Nucor Steel-Arkansas v. Ark. Pollution
    Control & Ecology Comm’n (Nucor I), 
    478 S.W.3d 232
    (Ark. 2015); Nucor Steel-
    Arkansas v. Big River Steel, LLC (Nucor II), 
    825 F.3d 444
    (8th Cir. 2016). 2
    Significantly for present purposes, Nucor has also sought to challenge Big River
    Steel’s permit by petitioning the EPA to object to the permit under Title V of the CAA,
    42 U.S.C. §§ 7661–7661f. Per Title V, the EPA may object to any operating permit that
    a state permitting authority issues if the permit does not comply with the CAA, 
    id. § 7661d(b)(1),
    and if EPA fails to object on its own, any person may petition the agency
    to issue an objection, 
    id. § 7661d(b)(2).
    When the EPA failed to respond timely to
    Nucor’s petition for an objection to Big River Steel’s permit, Nucor filed this lawsuit,
    seeking a court order that compels the EPA to respond to Nucor’s petition. (See
    Compl., Prayer for Relief, ¶ B.)
    Before this Court at present is the EPA’s motion to dismiss Nucor’s complaint.
    (See EPA’s Mot. to Dismiss Second Suppl. & Am. Compl. for Lack of Jurisdiction
    (“Mot.”), ECF No. 43.) In the motion, the agency contests Nucor’s various stated bases
    for Article III standing, only one of which this Court finds worthy of discussion here. 3
    1
    Big River Steel is participating in this lawsuit as an amicus curiae. (See Order, ECF No. 34.)
    2
    Both of these legal challenges were ultimately unsuccessful. See Nucor 
    I, 478 S.W.3d at 236
    –37;
    Nucor 
    II, 825 F.3d at 446
    –47.
    3
    In order to demonstrate that it has standing to sue, a plaintiff needs to identify only one type of
    cognizable injury-in-fact, and therefore, a court “need not address” alternative theories of injury once
    2
    Specifically, Nucor’s complaint asserts that, by operation of a set of rules within the
    CAA known as the Prevention of Significant Deterioration (“PSD”) program, the
    permitted emissions from the new Big River Steel mill will cause a construction project
    that Nucor has planned to undertake at one of its Arkansas facilities to be subject to
    more stringent emissions limitations than would have applied to Nucor’s project
    otherwise. (See Compl. ¶¶ 63, 71–81.) The EPA argues that Nucor has not adequately
    alleged that Big River Steel’s permit will cause Nucor imminent injury in this way,
    because the complaint does not sufficiently assert that Nucor has any imminent
    construction plans that will require PSD-program review or that such plans would
    actually be affected by Big River Steel’s emissions. (See Mot. at 18–23.) 4
    For the reasons explained below, this Court agrees with Nucor that certain
    allegations in the complaint are sufficient to demonstrate (for the purpose of the
    pleading stage of this litigation) that Big River Steel’s permit works a plausible and
    imminent injury to Nucor in the form of more stringent limitations under the PSD
    program. (See, e.g., Compl. ¶ 78 (alleging that one of Nucor’s facilities “is currently
    pursuing permit modifications that may require PSD review”); 
    id. ¶ 28
    (asserting that
    Big River Steel’s emissions “will impact the overall air quality of Mississippi County,
    including the air quality in and around Nucor’s facilities”).) Consequently, this Court
    finds that the complaint adequately alleges Nucor’s standing to bring the instant
    lawsuit, which means that the EPA’s motion to dismiss for lack of standing must be
    DENIED. A separate order consistent with this Memorandum Opinion will follow.
    one injury-in-fact is established. Sierra Club v. EPA, 
    755 F.3d 968
    , 976 n.2 (D.C. Cir. 2014).

    I.     BACKGROUND
    This Memorandum Opinion addresses the EPA’s contention that Nucor lacks
    Article III standing because its complaint does not adequately allege that Nucor has
    imminent construction plans that the emissions from Big River Steel’s new facility will
    affect by operation of the PSD program. Notably, the EPA appears to accept Nucor’s
    suggestion that an injury of the type Nucor alleges can constitute a concrete,
    particularized injury that would confer Article III standing if an entity that has
    imminent construction plans demonstrates that it actually would be harmed in this way.
    In order to evaluate the EPA’s assertion that Nucor’s complaint fails to make an
    adequate showing of imminent injury, it is important to understand how the operation of
    the PSD program could possibly inflict a cognizable injury-in-fact for standing
    purposes, and achieving that understanding requires background knowledge of the
    overall CAA scheme and the contours of the PSD program, both of which are sketched
    out below.
    A.     The Clean Air Act Framework
    With the CAA Amendments of 1970, Congress enacted a “comprehensive
    national program that made the States and the Federal Government partners in the
    struggle against air pollution.” Gen. Motors Corp. v. United States, 
    496 U.S. 530
    , 532
    (1990). At the heart of the CAA are the National Ambient Air Quality Standards
    (“NAAQS”), which are specified numerical thresholds for the concentration of
    particular pollutants in the outdoor air (also known as the “ambient” air). See 42 U.S.C.
    § 7409. Because of their role within the overall statutory scheme, the NAAQS are
    generally considered to be “the engine that drives nearly all of Title I of the CAA.”
    Whitman v. Am. Trucking Ass’ns, 
    531 U.S. 457
    , 468 (2001).
    4
    The CAA requires the EPA “to promulgate NAAQS for each air pollutant” about
    which the agency has made certain findings, 
    id. at 462;
    see also 42 U.S.C. § 7409(a),
    and the agency must set these uniform, nationally applicable pollution standards at the
    levels necessary “to protect the public health,” 42 U.S.C. § 7409(b)(1), while also
    providing for “an adequate margin of safety,” 
    id., and “accurately
    reflect[ing] the latest
    scientific knowledge” about the effects on public health from the presence of each
    pollutant in the ambient air, 
    id. § 7408(a)(2).
    To date, the EPA has promulgated
    NAAQS for six types of air pollutants. Util. Air Regulatory Grp. v. EPA (UARG), 
    134 S. Ct. 2427
    , 2435 (2014); see 40 C.F.R. pt. 50. As pertinent here, there are two
    NAAQS that relate to a pollutant called “particulate matter”: one that applies to PM 2.5
    and another that applies to PM 10 . See 40 C.F.R. §§ 50.6 (setting NAAQS for PM 10 ),
    50.13, 50.18 (setting NAAQS for PM 2.5 ). 5
    The States’ Role In The Regulation Of New And Modified
    Stationary Sources Under The CAA
    Once the EPA establishes a NAAQS for a particular pollutant, each state assumes
    the lead role in implementing that air quality standard, with each state adopting (subject
    to EPA approval) “a plan which provides for implementation, maintenance, and
    enforcement” of that NAAQS. 42 U.S.C. § 7410(a)(1). 6 Each state’s implementation
    plan (“SIP”) is subject to certain minimum requirements laid out in the CAA, see 
    id. § 7410(a)(2),
    but “[i]t is to the States that the CAA assigns initial and primary
    responsibility for deciding what emissions reductions will be required from which
    5
    These two NAAQS reflect different particle sizes. PM 2.5 takes account of particles with a diameter of
    2.5 micrometers or less, while PM 10 takes account of particles with a diameter of 10 micrometers or
    less. See 40 C.F.R. §§ 50.6, 50.7, 50.13.
    6
    The EPA has approved Arkansas’s SIP. See 40 C.F.R. §§ 52.170, 52.172.
    5
    sources” in order to achieve the NAAQS. Am. Trucking 
    Ass’ns, 531 U.S. at 470
    ; see
    also 42 U.S.C. § 7407(a) (“Each State shall have the primary responsibility for assuring
    air quality within the entire geographic area comprising such State by submitting [a
    SIP] which will specify the manner in which [the NAAQS] will be achieved and
    maintained within each air quality control region in such State.”).
    As a general matter, through its SIP, each state implements a permit program that
    requires each new and modified major stationary source of pollution to seek a pre-
    construction permit that sets emissions limitations for that source. See Texas v. EPA,
    
    726 F.3d 180
    , 183–84 (D.C. Cir. 2013); see also 42 U.S.C. §§ 7410(a)(2)(C). For
    example, in Arkansas, the ADEQ issues pre-construction permits, Nucor 
    II, 825 F.3d at 447
    ; see Ark. Code §§ 8-4-201, 203, and any entity that plans to build a new major
    emitting facility, or modify an existing one, must apply to the ADEQ for a permit that,
    if granted, contains allowable emissions levels pertaining to that source, Nucor 
    II, 825 F.3d at 447
    .
    Importantly, the particular emissions limitations that apply to a new or modified
    source depend on where the source is located. The EPA divides the country into “air
    quality control regions” and classifies each region as being in “attainment,” or in “non-
    attainment,” or treats the region as “unclassifiable,” with respect to each NAAQS. 42
    U.S.C. § 7407(d)(1)(B); see 40 C.F.R. pt. 81, subparts B–C. And these designations
    dictate which emissions limitations the states must impose in any pre-construction
    permits that they issue in a particular region. See 42 U.S.C. §§ 7475 (setting permit
    requirements for sources in “attainment” and “unclassifiable” regions), 7503 (setting
    permit requirements for sources in “non-attainment” regions).
    6
    In essence, “the [CAA] triggers more or less stringent [emissions] requirements
    depending on the quality of an area’s ambient air.” Catawba Cty, N.C. v. EPA, 
    571 F.3d 20
    , 26 (D.C. Cir. 2009). Furthermore, the EPA can change a region’s designation
    “at any time[,]” based on “any . . . air quality-related considerations the Administrator
    deems appropriate[.]” 42 U.S.C. § 7407(d)(3)(A).
    The PSD Program
    In regions that have been designated “attainment” or “unclassifiable,” the CAA
    requires states to implement the statute’s Prevention of Significant Deterioration
    (“PSD”) program. See 
    id. § 7471.
    The PSD program is so named because, in
    attainment and unclassifiable regions, the pre-construction permits that states issue have
    to impose the emissions limitations that are “necessary . . . to prevent significant
    deterioration of air quality,” 42 U.S.C. § 7471 (emphasis added); hence, the pre-
    construction permits that the states issue in those regions are known as “PSD permits,”
    Alaska Dep’t of Envtl. Conservation v. EPA, 
    540 U.S. 461
    , 470, 472 (2004). When a
    major new or modified emitting facility seeks a PSD permit, it is required to certify that
    it will comply with a number of requirements. See 42 U.S.C. § 7475. One such
    requirement is that the new or modified facility must employ the best available control
    technology (“BACT”) for each pollutant subject to the PSD program. 
    Id. § 7475(a)(4).
    Another is that the facility must “demonstrate[]” that its emissions “will not cause, or
    contribute to, air pollution in excess of any . . . [NAAQS] in any air quality control
    region[.]” 
    Id. § 7475(a)(3).
    In addition, and importantly for this case, the applicant must also
    “demonstrate[]” that its emissions “will not cause, or contribute to, air pollution in
    excess of any . . . maximum allowable increase or maximum allowable concentration
    7
    for any pollutant in any area [subject to the PSD program] more than one time per
    year[.]” 
    Id. With respect
    to this last requirement, the “maximum allowable increase”
    for a particular pollutant is known as the PSD “increment.” Alaska Dep’t of Envtl.
    
    Conservation, 540 U.S. at 473
    ; see also 42 U.S.C. § 7473 (setting “increments” for
    specific pollutants).
    The PSD increment is a number that is expressed as an ambient concentration of
    a given pollutant in micrograms per meter cubed (µg/m 3 ), and it reflects “the maximum
    allowable increase in concentration[ of a pollutant] . . . over the baseline
    concentration.” 42 U.S.C. § 7473(b)(2); see also 40 C.F.R. § 52.21(c) (setting PSD
    increments). The EPA establishes the “baseline concentration” for a given pollutant,
    and the baseline, which varies from region to region, is generally equal to the
    concentration of the pollutant that was present in the ambient air at the time the first
    application for a PSD permit in a particular region was submitted. See 42 U.S.C.
    § 7479(4); see also 40 C.F.R. § 52.21(b)(13)–(15). The PSD increment—which, as
    explained, is the maximum allowable increase above the baseline—is a single number
    that the EPA fixes for each pollutant, and it applies to all regions that have been
    designated as “attainment” or “unclassifiable” with respect to that pollutant; for
    example, in the case of PM 2.5 and PM 10 , the established PSD increments are 4 and 17
    µg/m 3 , respectively. See 40 C.F.R. § 52.21(c). 7 What this means, as a general and
    practical matter, is that all new or modified stationary sources of pollution in attainment
    7
    These numbers reflect the “annual arithmetic mean” PSD increments—that is, the maximum allowable
    increase in the ambient concentration of each pollutant as measured over the course of a year. See 40
    C.F.R. § 52.21(c). Moreover, these numbers apply in “Class II areas,” see 
    id., which the
    law defines as
    all areas other than certain large national and international parks, see 42 U.S.C. § 7472.
    8
    and unclassifiable areas must be mindful not to construct facilities whose emissions of a
    pollutant would cause the region to exceed the PSD increment for that pollutant.
    The method by which a new or modified facility must demonstrate that it will not
    “cause or contribute to” air pollution in excess of the PSD increment, 42 U.S.C.
    § 7475(a)(3), is critical to Nucor’s PSD-related theory of injury in this case. In brief,
    each PSD-permit applicant must begin by conducting an air quality impact analysis that
    identifies the area in which the proposed new or modified facility will have a
    significant impact on air quality. See 42 U.S.C. § 7475(a)(6); 40 C.F.R. § 52.21(m);
    see also Environmental Protection Agency, New Source Review Workshop Manual
    C.26–31 (Draft, Oct. 1990) (hereinafter “NSRWM”). This “impact area” is “a circular
    area” that is centered on the proposed facility and has a radius that extends out either 50
    kilometers or to the most distant point where air modeling suggests that a significant
    impact will occur, whichever is less. See NSRWM at C.26. Next, the PSD permit
    applicant must develop an inventory of “all increment-affecting sources located in the
    impact area” as well as “all increment-affecting sources located within 50 kilometers of
    the impact area . . . if they, either individually or collectively, affect the amount of PSD
    increment consumed.” 
    Id. at C.35.
    Sources are “increment-affecting” (and thus must
    be included in the inventory) if they have caused a change in emissions subsequent to
    the setting of the baseline concentration. See 
    id. Finally, after
    assembling this inventory of nearby sources that already affect the
    PSD increment, the permit applicant must demonstrate that its proposed facility, in
    conjunction with the pre-existing facilities, will not cause the PSD increment to be
    exceeded. See 40 C.F.R. § 52.21(k)(ii); see also 
    id. § 52.21(b)(13)(ii)(a)
    (explaining
    9
    that emissions from other sources constructed after the baseline concentration has been
    set “affect the applicable maximum allowable increase[]” that a new facility must take
    into account when applying for a PSD permit). Put another way, once the baseline
    concentration of a given pollutant has been set in a particular region, any facility
    constructed thereafter that increases the ambient concentration of that pollutant
    “consumes” a portion of the PSD increment, leaving less of the increment available for
    subsequent new facilities in the region to use. NSRWM at C.10.
    B.     Underlying Facts And Procedural History
    Big River Steel is currently constructing a steel mill near the town of Osceola in
    Mississippi County, Arkansas. (Compl. ¶¶ 1, 9.) Mississippi County is part of the
    Northeast Arkansas Intrastate Air Quality Control Region, see 40 C.F.R. § 81.139,
    which the EPA has classified as “attainment” or “unclassifiable” with respect to PM 2.5
    and PM 10 , see 
    id. § 81.304,
    and thus the area is subject to the PSD program, see 42
    U.S.C. § 7471.
    In January of 2013, Big River Steel applied to ADEQ for a pre-construction PSD
    permit related its new mill, and it did so at the same time that it sought an operating
    permit under Title V of the CAA with respect to the proposed new facility. See Nucor
    
    I, 478 S.W.3d at 237
    –38 & n.1. The basic requirements for seeking and receiving a
    PSD permit are described above, 
    see supra
    , Part I.A.2, while the purpose and
    procedures for operating permits under Title V—which is the vehicle pursuant to which
    the instant case is brought—are as follows.
    1.     The Title V Permitting Process
    Title V of the CAA mandates that each major stationary source obtain a facility-
    wide operating permit that lays out all federally enforceable emissions limitations
    10
    applicable to that facility. See Sierra Club v. EPA, 
    551 F.3d 1019
    , 1022 (D.C. Cir.
    2008); 42 U.S.C. §§ 7661–7661f. Title V “is designed to facilitate compliance and
    enforcement by consolidating into a single document all of a facility’s obligations under
    the Act.” 
    UARG, 134 S. Ct. at 2436
    . Title V operating permits are distinct from PSD
    permits, see 
    id. at 2435–36,
    but PSD-permit requirements are among the obligations
    that must be included in a Title V permit, see 40 C.F.R. § 70.2 (defining “applicable
    requirement” for the purposes of Title V to include “[a]ny term or condition of any
    preconstruction permits” issued under the PSD program). The EPA allows states to
    consolidate their PSD and Title V permits, see EPA, Operating Permit Program, 57 Fed.
    Reg. 32,250, 32,259 (July 21, 1992), and Arkansas has done so, see Nucor 
    II, 825 F.3d at 453
    ; Nucor 
    I, 478 S.W.3d at 238
    n.1. Moreover, having a Title V permit shields a
    facility from the charge of operating in violation of the CAA, because once a facility
    obtains a Title V permit, Title V’s “permit shield” provision dictates that “compliance
    with the permit shall be deemed compliance with” the statute. 42 U.S.C. § 7661c(f);
    see also Sierra 
    Club, 551 F.3d at 1022
    .
    Significantly for present purposes, Title V establishes that a state permitting
    authority must subject each Title V permit application to public comment and judicial
    review by the state’s courts, 42 U.S.C. § 7661a(b)(6), and it must also transmit all
    proposed Title V permits to the EPA for review, 
    id. § 7661d(a)(1).
    If, upon review of a
    Title V application, the EPA determines that the proposed Title V permit would violate
    the CAA in any respect, it “shall . . . object to its issuance” and “provide a statement of
    reasons for the objection” to the state permitting authority and to the permit applicant.
    
    Id. § 7661d(b)(1).
    If the state permitting authority receives an EPA objection, it may
    11
    respond by submitting a revised permit to the EPA, but it must refrain from issuing the
    permit. 42 U.S.C. § 7661d(b)(3). And once it has objected, the EPA makes the final
    decision whether to deny the permit or issue it with revisions, 
    id. § 7661d(c);
    consequently, an objection from the EPA is effectively a “veto[.]” Operating Permit
    Program, 57 Fed. Reg. at 32,256.
    However, if the EPA does not object within forty-five days of receiving a
    proposed Title V permit, “any person” may petition the EPA to object on any ground
    that was raised during the state permitting authority’s public comment period. 42
    U.S.C. § 7661d(b)(2). The EPA must grant or deny any such petition for an objection
    within sixty days of receiving it, and “shall issue an objection [i.e. grant the petition]
    within such period if the petitioner demonstrates . . . that the permit is not in
    compliance” with the CAA. 
    Id. 8 The
    EPA’s denial of a petition for an objection is
    subject to judicial review in the appropriate Court of Appeals. Id.; see also 
    id. § 7607(b)(1).
    9 In addition, if the EPA fails to take any action on the petition, the
    CAA’s citizen-suit provision supplies a cause of action for the petitioner to bring a suit
    against the EPA in federal district court for “a failure . . . to perform any act or duty
    under [the CAA] which is not discretionary[.]” 
    Id. § 7604(a)(2).
    8
    The EPA maintains an online list of Title V petitions and its decisions on those petitions. See EPA,
    Title V Petition Database, www.epa.gov/title-v-operating-permits/title-v-petition-database (last visited
    Mar. 29, 2017).
    9
    Because this pathway exists for judicial review of Title V permits, the CAA’s citizen suit provision,
    42 U.S.C. § 7604, does not encompass direct challenges to Title V permits in district court. See Nucor
    
    II, 825 F.3d at 452
    –53; Romoland Sch. Dist. v. Inland Empire Energy Ctr. LLC, 
    548 F.3d 738
    , 754–55
    (9th Cir. 2008). Of course, judicial review from a state permitting authority’s decision to grant a Title
    V permit is available in state court. 42 U.S.C. § 7661a(b)(6) (requiring state judicial review of Title V
    permitting decisions); see, e.g., Ark. Code §§ 8-4-205, 223(a)(1), (d) (prescribing judicial review for
    ADEQ permitting decisions in the Arkansas Court of Appeals); see also, e.g., Nucor I, 
    478 S.W.3d 232
    (reviewing ADEQ Title V permitting decision).
    12
    Big River Steel’s Permit Application And Nucor’s Response To It
    Big River Steel’s application to the ADEQ regarding the new steel mill that it
    proposed to build Osceola, Arkansas, contained an air quality analysis that predicted
    that the new mill would contribute 2.47 µg/m 3 to the ambient concentration of PM 2.5 in
    the region, bringing the total concentration to 11.91 µg/m 3 , just below the NAAQS of
    12 µg/m 3 . See Nucor 
    I, 478 S.W.3d at 237
    –38. 10 ADEQ issued a draft permit in June
    2013, which triggered a public comment period. 
    Id. at 238.
    Nucor had “actively
    followed” its prospective neighbor’s permit application, and it “submitted over forty
    comments” to ADEQ, “most objecting to the technical aspects of [Big River Steel]’s
    modeling and to a perceived bias in ADEQ’s evaluation of [Big River Steel]’s
    application.” 
    Id. Over Nucor’s
    vigorous objection, ADEQ issued a final permit on
    September 18, 2013. 
    Id. Nucor then
    proceeded to press its opposition to Big River Steel’s Osceola mill on
    several fronts. It appealed ADEQ’s permit, first, to the Arkansas Pollution Control and
    Ecology Commission, which affirmed the permit, and then to the Arkansas Court of
    Appeals, which in turn affirmed the Commission. Nucor 
    I, 478 S.W.3d at 236
    –37.
    Nucor also sued Big River Steel directly in the U.S. District Court for the Eastern
    District of Arkansas, challenging the permit under the portions of the CAA’s citizen-
    suit provision allowing for claims against private parties. See 42 U.S.C. § 7604(a)(1),
    (3). That court dismissed Nucor’s complaint for lack of subject matter jurisdiction, see
    Nucor Steel-Arkansas v. Big River Steel, LLC, 
    93 F. Supp. 3d 983
    , 992–93 (E.D. Ark.
    2015), and the Eighth Circuit affirmed, see Nucor 
    II, 825 F.3d at 447
    .
    10
    12 µg/m 3 represents the primary annual arithmetic mean NAAQS for PM 2.5 . See 40 C.F.R. § 50.18.
    13
    In addition, and directly relevant here, on October 9, 2013, Nucor petitioned the
    EPA to object to the permit under 42 U.S.C. § 7661d, raising many of the concerns that
    Nucor had previously flagged during ADEQ’s public comment period. (Compl. ¶¶ 95–
    96.) Among other things, Nucor asserted that, when ADEQ issued the permit to Big
    River Steel, ADEQ failed to monitor the pre-existing concentration of PM 2.5 properly,
    failed to model the air quality impacts of the Big River Steel mill, and failed to
    establish an appropriate BACT standard. (Compl. ¶ 57.)
    Procedural History
    The EPA did not respond to Nucor’s petition within the sixty-day statutory
    window. (See Compl. ¶ 97 (citing 42 U.S.C. § 7661d(b)).) After giving the agency the
    requisite notice of its intent to sue (see Compl. ¶ 92 (citing 42 U.S.C. § 7604(b)(2))),
    Nucor filed this lawsuit on February 11, 2014, alleging that the EPA’s ongoing failure
    to respond to Nucor’s petition constitutes “a failure of the Administrator to perform any
    act or duty . . . which is not discretionary[.]” 42 U.S.C. § 7604(a)(2). Nucor’s
    complaint seeks an order requiring the EPA to grant or deny its petition for an objection
    within 30 days. (See Compl., Prayer For Relief, ¶ B.)
    Since filing this lawsuit, Nucor has twice amended its complaint (once with the
    Court’s leave and once under Court order) in response to motions to dismiss
    challenging its standing to sue, and both times, Nucor has expanded the complaint’s
    allegations in support of standing. (See Pl.’s Mot. for Leave to File First Suppl. & Am.
    Compl, ECF No. 19; Mot. for Leave to File Second Suppl. & Am. Compl., ECF No. 39.)
    14
    In its now-operative pleading, which is titled the Second Supplemental and Amended
    Complaint, Nucor asserts several theories of injury. 11
    First, Nucor alleges that particulate matter emissions from the new Big River
    Steel facility “will reach the Nucor mills given the short distance between them,” and
    “will negatively impact Nucor’s employees’ health and productivity, which impacts the
    operations at Nucor’s facilities.” (Compl. ¶¶ 27, 29.) Second, Nucor alleges that
    particulate matter emissions from the Big River Steel facility will damage Nucor’s
    property by polluting a 350-acre wildlife area that Nucor preserves for its employees’
    leisure (see 
    id. ¶¶ 36–52),
    and by “stain[ing] and damag[ing] buildings and other
    property owned by Nucor” (id. ¶ 54). Third, Nucor alleges that it will suffer
    competitive injury if ADEQ issues permits to Nucor in the future that, either initially or
    as the result of an EPA objection, impose emissions limitations on Nucor that should
    have been, but were not, imposed on Big River Steel. (See 
    id. ¶¶ 57–62).
    Fourth,
    Nucor alleges that Big River Steel’s Title V permit contains unrealistic BACT
    requirements, which will force Nucor to implement more expensive emissions control
    technologies in the future when it submits its own permit applications. (See 
    id. ¶¶ 82–
    86.) Fifth, Nucor alleges that emissions from the Big River Steel facility will cause the
    ambient concentration of PM 2.5 to exceed the NAAQS (see 
    id. ¶ 63),
    which “will result
    in Mississippi County being reclassified as ‘nonattainment’” (id. ¶ 64), leading to
    additional regulatory burdens for Nucor (see 
    id. ¶¶ 65–68).
    Sixth and finally, Nucor
    alleges that emissions from the Big River Steel facility will partially or completely
    11
    For simplicity’s sake, the Court refers to the Second Supplemental and Amended Complaint as “the
    complaint” throughout this opinion.
    15
    consume the regional PSD increments for PM 2.5 and PM 10 , constraining any future
    Nucor construction project that generates particulate matter emissions and that requires
    PSD review. (See 
    id. ¶¶ 63,
    72–81.)
    With respect to the contention that the Big River Steel mill will consume some or
    all of the pertinent PSD increment, Nucor alleges, first of all, that it is “nearly certain”
    that its two mills in Arkansas will undergo PSD review in connection with future
    modification projects. (Id. ¶ 78.) Furthermore, in support of this prediction, Nucor
    alleges that both of its mills have previously been subject to PSD review (see 
    id. ¶¶ 4–
    5); that one of its two mills “is currently pursuing permit modifications that may require
    PSD review” (id. ¶ 78); and that over the past 25–30 years, its two mills have averaged
    almost an ADEQ-air-permit modification per year apiece, “[m]any” of which required
    PSD review (id.). Nucor also alleges that any PSD permit applications that it might
    seek in the future will be meaningfully constrained by Big River Steel’s emissions (see
    
    id. ¶¶ 78,
    80–81), because Big River Steel’s new facility is located just 20 miles upwind
    of Nucor’s mills (see 
    id. ¶¶ 10–11)
    and is in the same air quality control region as
    Nucor’s mills (see 
    id. ¶ 8),
    and Nucor maintains that Big River Steel’s new mill will
    emit particulate matter that “will reach the Nucor mills” (id. ¶ 27) and “impact the
    overall air quality in Mississippi County” (
    id. ¶ 28
    ).
    In its pending motion to dismiss, the EPA argues that Nucor lacks standing to
    sue because none of its asserted injuries amounts to an “injury-in-fact” that is
    cognizable under Article III of the Constitution. (See generally Mot.) The agency
    makes compelling arguments that Nucor’s assertions of injury related to its employees
    and property rely on speculation about increased risk of harm and fail to account for
    16
    Nucor’s own emissions (see 
    id. at 11–14),
    and that Nucor’s assertions of competitive
    injury, injury related to BACT standards, and injury arising from an exceedance of the
    NAAQS all rely on speculation about the unpredictable future conduct of third-party
    regulators (see 
    id. at 14–17).
    As for Nucor’s PSD-increment theory of standing, the EPA maintains that
    Nucor’s complaint contains insufficient allegations of fact to support a finding of
    standing insofar as it fails to allege adequately that Nucor will imminently need to
    secure a PSD permit or that any such permit would likely be more restrictive as a result
    of emissions from the Big River Steel facility. (See 
    id. at 18–23.)
    Nucor responds that
    its complaint references a permit modification that one of its Arkansas facilities is
    currently pursuing, and thus Big River Steel’s consumption of the PSD increment
    affects Nucor’s present behavior. (See Nucor’s Req. for Oral Arg. & Opp’n to EPA’s
    Mot. to Dismiss Second Suppl. & Am. Compl. for Lack of Jurisdiction (“Opp’n”), ECF
    No. 47, at 37.) Nucor also argues that even if those present effects are insufficient to
    confer standing, Nucor has adequately alleged that it will need PSD permits in the
    future and that those permits will be impacted by Big River Steel’s emissions. (Id. at
    37–39.)
    The EPA’s motion to dismiss Nucor’s complaint for lack of standing is now ripe
    for decision (see Mot.; Opp’n; EPA’s Reply in Supp. of Mot. to Dismiss Second Suppl.
    & Am. Compl. for Lack of Jurisdiction (“Reply”), ECF No. 50); this Court held a
    hearing on the motion on May 17, 2016. 12
    12
    Big River Steel has attempted to participate in this lawsuit in several respects. It has sought leave to
    intervene (ECF No. 9), which the Court denied (Order, ECF No. 34); leave to file briefs in support of
    EPA as an amicus curiae (ECF Nos. 23, 29, 45), which the Court granted (Order, ECF No. 34; Min.
    Order of Nov. 18, 2015); and leave to participate in the Court’s two Motion Hearings (ECF Nos. 36,
    17
    II.    LEGAL STANDARDS
    A. Motions To Dismiss For Lack of Standing Under Rule 12(b)(1)
    Article III of the Constitution limits the judicial power of the federal courts to
    “[c]ases” and “[c]ontroversies[,]” U.S. Const. art. III, § 2, and that limitation creates a
    jurisdictional requirement that the plaintiff have standing to sue. See Lujan v. Defs. of
    Wildlife, 
    504 U.S. 555
    , 560 (1992). Because it is a plaintiff’s burden to demonstrate
    that the court has jurisdiction over his claims, “[e]very plaintiff in federal court bears
    the burden of establishing the three elements that make up the ‘irreducible
    constitutional minimum’ of Article III standing: injury-in-fact, causation, and
    redressability.” Dominguez v. UAL Corp., 
    666 F.3d 1359
    , 1362 (D.C. Cir. 2012)
    (quoting Defs. of 
    Wildlife, 504 U.S. at 560
    –61). Thus, to establish standing in a lawsuit
    that seeks an injunction, “a plaintiff must show that he is under threat of suffering
    ‘injury in fact’ that is concrete and particularized; the threat must be actual and
    imminent, not conjectural or hypothetical; it must be fairly traceable to the challenged
    action of the defendant; and it must be likely that a favorable judicial decision will
    prevent or redress the injury.” Summers v. Earth Island Inst., 
    555 U.S. 488
    , 493 (2009)
    (citation omitted).
    Courts consider motions to dismiss a complaint for lack of standing pursuant to
    Federal Rule of Civil Procedure 12(b)(1). See, e.g., Am. Freedom Law Ctr. v. Obama,
    
    821 F.3d 44
    , 48 (D.C. Cir. 2016). In evaluating whether the plaintiff has established
    the three elements of standing, the Court must be mindful of the stage of the litigation,
    because “each element must be supported in the same way as any other matter on which
    55), which the Court denied (Min. Order of Jan. 6, 2015; Min. Order of Feb. 29, 2016).
    18
    the plaintiff bears the burden of proof, i.e., with the manner and degree of evidence
    required at the successive stages of the litigation.” Defs. of 
    Wildlife, 504 U.S. at 561
    ;
    accord Food & Water Watch, Inc. v. Vilsack, 
    808 F.3d 905
    , 912–13 (D.C. Cir. 2015).
    Thus, at the pleading stage, “a complaint must state a plausible claim” that the elements
    of standing are satisfied, Humane Soc’y of U.S. v. Vilsack, 
    797 F.3d 4
    , 8 (D.C. Cir.
    2015) (emphasis added) (citing Ashcroft v. Iqbal, 
    556 U.S. 662
    , 678 (2009)), and when
    deciding whether the plaintiff’s assertion of standing is plausible, “the court must
    accept as true all of the factual allegations in the complaint and draw all reasonable
    inferences in favor of the plaintiff, but the court need not ‘accept inferences
    unsupported by the facts or legal conclusions that are cast as factual allegations.’” Cal.
    Clinical Lab. Ass’n v. Sec. of Health & Human Servs., 
    104 F. Supp. 3d 66
    , 74 (D.D.C.
    2015) (quoting Rann v. Chao, 
    154 F. Supp. 2d 61
    , 63 (D.D.C. 2001)). Finally, while
    reviewing a motion to dismiss pursuant to Rule 12(b)(1), the Court may consider
    material outside of the pleadings as it deems appropriate. Am. Freedom Law 
    Ctr., 821 F.3d at 49
    .
    B.     When The Plaintiff Alleges A Procedural Violation, Some Standing
    Requirements Are Relaxed But Others Are Not
    Often, a plaintiff who is injured by a government action (or its failure to act)
    sues to rectify the government’s violation of a procedural requirement that is connected
    to the substantive action. In such a lawsuit, a plaintiff “who has been accorded a
    procedural right to protect his concrete interests can assert that right without meeting
    all the normal standards for redressability and immediacy.” Defs. of 
    Wildlife, 504 U.S. at 572
    n.7. This principle means that the plaintiff need not demonstrate that correcting
    the procedural violation itself would necessarily remedy the injurious government
    19
    action, so long as “there is some possibility” that it would do so. Massachusetts v.
    EPA, 
    549 U.S. 497
    , 518 (2007). Thus, for example, “one living adjacent to the site for
    proposed construction of a federally licensed dam has standing to challenge the
    licensing agency’s failure to prepare an environmental impact statement, even though
    he cannot establish with any certainty that the statement will cause the license to be
    withheld or altered, and even though the dam will not be completed for many years.”
    Defs. of 
    Wildlife, 504 U.S. at 572
    n.7.
    Be that as it may, alleging a procedural violation does not excuse a plaintiff from
    having to identify a related, substantive government action that actually does (or
    imminently will) cause him concrete injury in order to establish standing to sue. Put
    another way, “the requirement of injury in fact is a hard floor of Article III
    jurisdiction[,]” and courts have long held that “a procedural right in vacuo . . . is
    insufficient to create Article III standing.” Earth Island 
    Inst., 555 U.S. at 496
    , 497.
    Thus, returning to the dam example: the adjacent property owner has standing to
    demand an environmental impact statement, notwithstanding the small chance that the
    statement will change the government’s decision to license the dam, and without regard
    to the fact that construction of the dam is years away (i.e., not imminent). However,
    “persons who live (and propose to live) at the other end of the country from the dam”
    would not have standing to file suit to enforce the impact-statement requirement. Defs.
    of 
    Wildlife, 504 U.S. at 572
    n.7. This is because the law permits a somewhat attenuated
    connection between the allegedly botched procedure and the underlying injurious
    substantive action, but there must always be a causal link between the underlying
    substantive action and the plaintiff’s injury. See WildEarth Guardians v. Jewell, 738
    
    20 F.3d 298
    , 306 (D.C. Cir. 2013); see also Nat’l Ass’n of Home Builders v. EPA, 
    667 F.3d 6
    , 15 (D.C. Cir. 2011) (noting that the injurious action must be one “that would
    otherwise confer Article III standing” if challenged directly (quoting United Transp.
    Union v. ICC, 
    891 F.2d 908
    , 918 (D.C. Cir. 1989))). Thus, even a plaintiff whose
    procedural rights have been violated cannot establish standing “[w]ithout an imminent
    threat of injury traceable to the challenged action[.]” Nat’l Ass’n of 
    Homebuilders, 667 F.3d at 15
    .
    III.   ANALYSIS
    In its motion to dismiss, the EPA argues that Nucor has failed to establish that it
    will suffer an injury-in-fact as a result of the agency’s failure to respond to Nucor’s
    petition, because Nucor has not demonstrated that it will be harmed by the underlying
    substantive decision at issue (i.e., the EPA’s failure to object to the permit that ADEQ
    issued to Big River Steel). (See Mot. at 10–23.) As noted, the agency has dutifully
    attacked each of the myriad bases upon which Nucor claims that the emissions from Big
    River Steel’s new plant will injure it. (See, e.g., 
    id. at 13
    (arguing that Nucor cannot
    claim that it is injured by damage that Big River Steel’s emissions will cause to its
    property because the “emissions from Nucor’s own mills exceed the permitted
    emissions from Big River”).) Nevertheless, as explained below, this Court concludes
    that Nucor has asserted a concrete and particularized injury resulting from ADEQ’s
    approval of Big River Steel’s new mill, insofar as Nucor plausibly contends that its
    current plans to modify its own existing plants are likely to require PSD review yet Big
    River Steel’s new facility will consume all or most of the applicable PSD increment.
    This Court also finds that correcting the EPA’s alleged procedural violation would
    21
    create the requisite possibility of redress for this PSD-increment injury, and as a result,
    Nucor’s complaint adequately alleges that Nucor has standing to sue.
    A.     Nucor Has Adequately Alleged An Injury-In-Fact
    For the following reasons, this Court concludes that Nucor’s alleged PSD-
    increment injury is “concrete and particularized[,]” and is also “actual or imminent, not
    conjectural or hypothetical.” Defs. of 
    Wildlife, 504 U.S. at 560
    (internal quotation
    marks and citations omitted).
    Consumption Of The PSD Increment Is A Concrete, Particularized
    Injury
    As explained above, when a major emitting facility seeks permission to embark
    on a construction project that requires PSD review, it must demonstrate that its
    emissions will not “cause or contribute to” an exceedance of any applicable PSD
    increment. 42 U.S.C. § 7475(a)(3). If other nearby facilities have already emitted
    significant amounts of a pollutant, those prior emissions consume the corresponding
    PSD increment, leaving less behind for a proposed construction project to consume.
    See 40 C.F.R. § 52.21(b)(13)(ii) (providing that emissions from other sources “affect
    the applicable maximum allowable increase[]” that a new facility must take into account
    when applying for a PSD permit); see also NSRWM at C.26, 34–35 (explaining that a
    facility must account for other increment-affecting sources within the area in which it
    will have a significant impact). Under this regulatory regime, the mechanics of which
    the EPA has laid out in a document called “The New Source Review Workshop
    Manual,” if one facility is allowed to emit a given pollutant in a given region, its action
    meaningfully constrains many of the future construction projects of its pollution-
    22
    emitting neighbors. See NSRWM at C.34–35. 13 Thus, it is clear to this Court that
    consumption of the PSD increment is a concrete and particularized harm that qualifies
    as an injury-in-fact for the purpose of Article III standing.
    First of all, there can be little doubt that PSD-increment injury is a concrete
    harm. See Spokeo, Inc. v. Robins, 
    136 S. Ct. 1540
    , 1548 (2016) (“A ‘concrete’ injury
    must be ‘de facto’; that is, it must actually exist.”). The Supreme Court has recognized
    a variety of “concrete” injuries, ranging from the tangible, Vt. Agency of Natural Res. v.
    United States ex rel. Stevens, 
    529 U.S. 765
    , 772 (2000) (loss of money); Lucas v. S.C.
    Coastal Council, 
    505 U.S. 1003
    , 1012 & n.3 (1992) (loss of real property), to the
    intangible, see Pub. Citizen v. U.S. Dep’t of Justice, 
    491 U.S. 440
    , 449 (1989)
    (informational harm); Sierra Club v. Morton, 
    405 U.S. 727
    , 734 (1972) (aesthetic
    harm). Ultimately, the word “concrete” is “meant to convey the usual meaning of the
    term—‘real,’ and not ‘abstract.’” Spokeo, 
    Inc., 136 S. Ct. at 1548
    (citations omitted).
    A government action that restricts a plaintiff’s ability to emit pollution—and thus limits
    its ability to operate a manufacturing facility as it chooses—doubtless inflicts a
    concrete injury on that plaintiff. See 
    UARG, 134 S. Ct. at 2445
    . Accordingly, when a
    permit enables a polluter to consume all or part of the PSD increment such that a
    13
    The Environmental Appeals Board, an administrative tribunal within the EPA, has described the New
    Source Review Workshop Manual as follows:
    The New Source Review Workshop Manual is a draft document issued by EPA’s Air
    Quality Management Division in October 1990. It was developed for use in conjunction
    with new source review workshops and training, and to guide permitting officials.
    Although it is not accorded the same weight as a binding Agency regulation, it has been
    looked to by this Board as a statement of the Agency’s thinking on certain PSD issues.
    In re: Commonwealth Chesapeake Corp., 6 E.A.D. 764, *3 n.6 (EAB 1997). The Supreme Court has
    relied on the Manual for insight into how the EPA implements the PSD program. See Alaska Dep’t of
    Envtl. 
    Conservation, 540 U.S. at 476
    , 497; see also 
    UARG, 134 S. Ct. at 2457
    & n.1 (Alito, J.,
    concurring in part and dissenting in part).
    23
    neighboring permit applicant must promise reduced emissions in order to comply with
    the PSD program, the neighboring applicant suffers a concrete injury.
    Second, Nucor’s alleged PSD-increment injury is sufficiently particularized.
    The particularity requirement bars lawsuits that “rais[e] only a generally available
    grievance[,]” because a plaintiff is “seeking relief that no more directly and tangibly
    benefits him than it does the public at large[.]” Defs. of 
    Wildlife, 504 U.S. at 573
    –74.
    A lawsuit to redress PSD-increment injury does not raise a mere generalized grievance:
    the PSD increment is a scarce resource within a confined geographical area, and its
    scarcity constrains only prospective polluters within that region. See 42 U.S.C.
    § 7475(a)(3)(A) (providing that a PSD-permit applicant must demonstrate that its
    emissions will not cause or contribute to an exceedance of the PSD increment “in any
    area” governed by the PSD program). When one facility’s consumption of a PSD
    increment subjects its neighbor’s imminent construction plans to more stringent
    emissions limitations under the PSD program, the neighbor is “affect[ed] . . . in a
    personal and individual way[,]” and its injury is therefore particularized. Defs. of
    
    Wildlife, 504 U.S. at 560
    n.1; cf. La. Energy & Power Auth. v. FERC, 
    141 F.3d 364
    , 367
    (D.C. Cir. 1998) (explaining that when a government action benefitting one entity
    increases competitive pressures on another entity within the same market, the second
    entity can establish an injury-in-fact under a competitor-standing theory).
    Moreover, as explained at the outset, the EPA ultimately does not dispute that a
    PSD-increment injury—when plausibly alleged by a pollution emitter with genuinely
    imminent construction plans that will be constrained by a neighbor’s emissions—
    constitutes a concrete and particularized injury that is cognizable under Article III.

    (See Mot. at 19 n.9 (describing allegations Nucor would need to make “[t]o show injury
    based on an alleged overconsumption of the increment”).) Instead, the EPA argues that,
    given the circumstances presented in Nucor’s complaint, Nucor has not adequately
    alleged that such an injury is imminent. (See Mot. at 18–23.) This Court disagrees, for
    the reasons explained below.
    Nucor Has Adequately Alleged That The Asserted PSD-Increment
    Injury Is Imminent
    In its complaint, Nucor specifically alleges that, due to ADEQ’s decision to grant
    the Big River Steel permit, when Nucor undertakes to “evaluat[e] whether a future
    modification” to one of its facilities “will contribute to an exceedance of the NAAQS or
    an exceedance of the PSD increment,” Nucor “will have to take the additional BRS
    emissions into account . . . , which will constrain [Nucor]’s ability to obtain permit
    modifications without additional pollution controls or operating restrictions.” (Compl.
    ¶ 81.) The EPA’s primary response to Nucor’s PSD-increment theory of injury is that
    Nucor has not plausibly alleged that it is in fact “planning modifications [to its mills]
    that would require a PSD permit” (Mot. at 18), or that there is an “overlap between the
    geographic areas affected by Nucor’s emissions and the emissions from the Big River
    facility” such that Big River Steel’s emissions would “affect the amount of increment
    available to Nucor” (id. at 20). According to the EPA, these two inadequacies render
    the allegations in Nucor’s complaint “insufficient to establish that the permitting of
    emissions from Big River causes an actual or imminent injury to Nucor.” (Id. at 18.)
    But the EPA’s contention disregards the pleading standards applicable at this early
    stage of the litigation, which require only that Nucor plausibly allege that the asserted
    PSD-increment injury is imminent.
    25
    Specifically, where, as here, a plaintiff’s assertion of injury depends on the
    plaintiff’s own future plans, courts examine whether the injury is imminent from two
    angles: the firmness of the plaintiff’s future plans, and the likelihood that the
    challenged government action will implicate those plans. See, e.g., In re Navy
    Chaplaincy, 
    697 F.3d 1171
    , 1176 (D.C. Cir. 2012); NB ex rel. Peacock v. District of
    Columbia, 
    682 F.3d 77
    , 83 (D.C. Cir. 2012). For example, in In re Navy Chaplaincy, a
    group of military chaplains alleged future injury in the form of religious discrimination
    by selection boards that would consider their future candidacies for 
    promotion. 697 F.3d at 1175
    –76. The D.C. Circuit assessed that “assertion of future injury” by dividing
    the contention into “two subsidiary premises: that plaintiffs will be considered for
    promotion by future selection boards and that selection boards will discriminate against
    them.” 
    Id. at 1176.
    The court proceeded similarly in NB ex rel. Peacock. 
    See 682 F.3d at 83
    . That is, in order to evaluate whether the plaintiff had adequately alleged future
    denial of Medicaid prescription coverage without the requisite notice, the court
    subdivided its analysis into the “contingencies” of (1) “whether [the plaintiff] ha[d]
    alleged an ongoing need for prescription coverage[,]” and (2) whether the defendant
    agency was “likely to . . . den[y] coverage . . . [and] fail to provide the required notice
    upon denial.” 
    Id. And these
    twin inquiries regarding (1) the plaintiff’s future plans,
    and (2) the likelihood that the challenged government action will implicate those plans,
    are parallel perspectives from which to examine the ultimate issue: whether, in light of
    the plaintiff’s allegations, it is plausible that the alleged injury is imminent. See 
    id. at 85–86.
    26
    With respect to Nucor’s future plans, this court finds that Nucor has adequately
    alleged that its future construction projects will require a PSD permit. Nucor asserts
    that it is “nearly certain” that its two mills in Arkansas will undergo PSD review in
    connection with future modification projects. (Compl. ¶ 78.) Furthermore, in support
    of this prediction, Nucor alleges that both of its mills have previously been subject to
    PSD review (Compl. ¶¶ 4–5); that one of its two mills “is currently pursuing permit
    modifications that may require PSD review” (Compl. ¶ 78); and that over the past 25–
    30 years, its two mills have averaged almost one ADEQ-air-permit modification per
    year apiece, “[m]any” of which required PSD review (id.). At this early stage of the
    litigation, these allegations suffice to support a plausible inference that Nucor will soon
    embark on a construction project that requires a PSD permit. See, e.g., 
    Peacock, 682 F.3d at 83
    (concluding that a plaintiff who had alleged that he needs two inhalers per
    month “is virtually certain” to engage in the conduct in the future that would subject
    him to injury); Dearth v. Holder, 
    641 F.3d 499
    , 502–03 (D.C. Cir. 2011) (holding that
    plaintiff’s “stated intent to return regularly to the United States” and purchase firearms
    made the injury that he would suffer in those circumstances “sufficiently real and
    immediate to support his standing” at the pleading stage); Emergency Coalition to
    Defend Educational Travel v. U.S. Dep’t of Treasury, 
    545 F.3d 4
    , 10 (D.C. Cir. 2008)
    (holding that the plaintiff had made adequate assertions regarding his future plans to
    lead a study-abroad program, where he described “the consistent annual repetition of
    the . . . program over several years” and his “concrete plans for the content and focus of
    the [upcoming year’s] program”).
    27
    The EPA’s argument regarding Nucor’s future intentions fails to appreciate the
    lower standard that is applicable at this phase of the litigation. (See Mot. at 18–19.)
    Citing the Supreme Court’s admonition in Defenders of Wildlife that “‘some day’
    intentions . . . do not support a finding of . . . ‘actual or imminent’ injury,” the EPA
    contends that Nucor’s “allegations are too vague and speculative” to establish that it has
    imminent construction plans that will require PSD review. (Mot. at 19 (quoting Defs. of
    
    Wildlife, 504 U.S. at 564
    ).) But Defenders of Wildlife was clear that its analysis was
    contingent on the case having arisen at the summary judgment 
    stage, 504 U.S. at 561
    ,
    and indeed the decision’s author clarified just weeks later that the standing challenge in
    Defenders of Wildlife “would have been unsuccessful” had it “been made at the
    pleading stage.” 
    Lucas, 505 U.S. at 1012
    n.3; see also Food & Water 
    Watch, 808 F.3d at 912
    –13.
    The EPA’s arguments regarding Nucor’s future plans are similarly misplaced.
    For example, the agency argues that Nucor’s allegation that it is “currently pursuing
    permit modifications that may require PSD review” (see Compl. ¶ 78) does not pass
    muster because many Title V permit modifications do not require PSD review. (See
    Mot. at 18–19 & nn.8–9 (emphasizing that PSD review is not required for changes that
    do not amount to “major modifications”)); see also 40 C.F.R. § 51.166(a)(7)(i),
    (b)(2)(i); Envt’l Def. v. Duke Energy Corp., 
    549 U.S. 561
    , 568–69 (2007). Moreover,
    the EPA continues, even those permit modifications that do require PSD review only
    entail PSD-increment analysis if the modification increases emissions of a pollutant by
    a “significant” amount. (Mot. at 18 n.8 (citing 40 C.F.R. § 51.166(b)(23), (m)(1)(i)).)
    But these criticisms simply identify the sorts of “‘specific facts that are necessary to
    28
    support the [complaint’s] claim’” of injury, Osborn v. Visa Inc., 
    797 F.3d 1057
    , 1063–
    64 (D.C. Cir. 2015) (emphasis added) (quoting Defs. of 
    Wildlife, 504 U.S. at 561
    ), and
    at the motion-to-dismiss stage, the court must “‘presum[e] that [the plaintiff’s] general
    allegations embrace’” such facts. 
    Id. (citation omitted).
    Consequently, Nucor’s failure
    to include in the complaint detailed allegations regarding the extent to which the
    planned permit modifications will actually and ultimately require PSD review does not
    undermine the plausibility of an inference that it has imminent construction plans that
    will require such review.
    As for the likelihood that Nucor’s future PSD permits will be subject to more
    stringent limitations as a result of Big River Steel’s emissions, Nucor has again alleged
    enough facts to move forward. In support of the complaint’s contention that Nucor’s
    future PSD permit applications will be meaningfully constrained by Big River Steel’s
    emissions (see Compl. ¶¶ 78, 80–81), the complaint alleges that Big River Steel’s new
    facility is located just 20 miles upwind of Nucor’s mills (see 
    id. ¶¶ 10–11)
    , is in the
    same air quality control region as Nucor’s mills (see 
    id. ¶ 8),
    and will emit particulate
    matter that “will reach the Nucor mills” (id. ¶ 27) and will “impact the overall air
    quality in Mississippi County” (
    id. ¶ 28
    ). Given these allegations (which the Court
    must accept as true), it is certainly plausible that Nucor’s future PSD permit
    applications will have to account for Big River Steel’s particulate matter emissions and
    that, as a result, Nucor will have to promise correspondingly lower new emissions in its
    future PSD permit applications.
    The EPA challenges Nucor’s allegations by pointing out that the operation of
    PSD-increment analysis described above means that “[t]here can be no injury to
    29
    Nucor’s ability to obtain permits without an actual overlap between the geographic
    areas affected by Nucor’s emissions and the emissions from the Big River facility—and
    Nucor has made no allegations regarding such an overlap.” (Mot. at 20 (emphasis
    added).) The agency adds that Nucor’s contentions about the geographical proximity
    between the facilities do not suffice to demonstrate actual overlap, because the
    “significant impact area” that would be used to determine restrictions on any future
    Nucor PSD permit is identified using complex air modeling that Nucor has not yet
    performed. (Id. at 21–22.)
    These arguments both overcomplicate the mechanics of the PSD-increment
    analysis and underestimate the importance of the litigation stage to a proper evaluation
    of a plaintiff’s injury assertions. As explained above, the “significant impact area” that
    Nucor will need to analyze in the context of any future PSD-permit application is a
    circular area that is centered on the relevant Nucor mill, see NSRWM at C.26, and
    Nucor’s analysis will need to account for “all increment-affecting sources located
    within 50 kilometers of the impact area[,]” 
    id. at C.35.
    Nucor’s allegations support
    inferences both that the distance between its mills and Big River Steel’s mill is less
    than 50 kilometers (see Compl. ¶ 10), and that Big River Steel’s mill is “increment-
    affecting” (see Compl. ¶ 79). What is more, Nucor also specifically alleges that Big
    River Steel’s emissions “will reach the Nucor mills[.]” (Compl. ¶ 27.); see also
    Catawba 
    Cty., 571 F.3d at 26
    (“PM 2.5 can travel hundreds or thousands of miles.”) 14
    14
    In this regard, the EPA points out that Nucor’s mills are not accessible to the public, which, says the
    agency, means that Nucor’s mills are not considered part of the “significant impact area” in any PSD
    increment analysis per the applicable regulations. (Mot. at 22 (citing 40 C.F.R. § 50.1(e) (defining
    “ambient air” for the purpose of the PSD program as “that portion of the atmosphere, external to
    buildings, to which the general public has access”)).) This argument is too clever by half, because it
    ignores the fact that the complaint’s allegation that Big River Steel’s emissions “will reach the Nucor
    30
    Thus, it is entirely plausible that Big River Steel’s emissions will reach the “significant
    impact area” that Nucor will need to analyze for one of its future construction projects,
    such that Nucor’s future PSD permits will be made more restrictive in light of Big
    River Steel’s emissions. As a result, this Court concludes that Nucor has adequately
    alleged for the purpose of the motion-to-dismiss stage that it faces imminent PSD-
    increment injury. See 
    Peacock, 682 F.3d at 83
    –84; see also Food & Water 
    Watch, 808 F.3d at 912
    –13 (explaining the lower bar for demonstrating standing that is applicable
    at the pleading stage). 15
    B.      Nucor Has Adequately Alleged That Its Injury Is Fairly Traceable To
    The EPA’s Conduct And Would Likely Be Redressed By A Favorable
    Outcome In This Lawsuit
    Finally, although the EPA does not dispute the causation and redressability
    aspects of Nucor’s purported standing, this Court will evaluate those standing elements,
    because the Court has “an independent obligation to assure [itself] that jurisdiction is
    proper.” Plains Commerce Bank v. Long Family Land & Cattle Co., 
    554 U.S. 316
    , 324
    (2008).
    mills” (Compl. ¶ 27) gives rise to the logical inference that Big River Steel’s emissions will also reach
    the publicly accessible land adjacent to those mills that is within the “significant impact area.”
    15
    Because this Court concludes that Nucor has adequately alleged an imminent PSD-increment injury,
    it need not (and will not) address Nucor’s alternative argument that it is already suffering a PSD-
    increment injury by virtue of the changes to its construction plans that it must make now in anticipation
    of future PSD-permit applications. (See Opp’n at 36–37.) It is doubtful that an anticipatory, self-
    inflicted injury confers standing unless the plaintiff undertakes the injurious act in anticipation of a
    certainly impending, externally-inflicted injury that would confer standing in its own right. See
    Clapper v. Amnesty Int’l USA, 
    133 S. Ct. 1138
    , 1151 (2013) (“[R]espondents cannot manufacture
    standing merely by inflicting harm on themselves based on their fears of hypothetical future harm that
    is not certainly impending.”). This Court has already opined about the heart of the instant impending-
    injury matter by concluding that Nucor’s alleged future PSD-increment injury is imminent. Thus, this
    Court sees no need to evaluate whether the plan change that Nucor is allegedly making at present in
    anticipation of the imminent PSD-increment injury confers standing in-and-of-itself.
    31
    With respect to causation, there can be little doubt that Nucor’s PSD-increment
    injury is fairly traceable to the EPA’s failure to object to Big River Steel’s permit. That
    is, if the EPA had objected, ADEQ would have been forbidden from issuing a Title V
    permit to Big River Steel, and Big River Steel could not construct or operate its mill.
    See 42 U.S.C. § 7661d(b)(3). It is likewise clear that the EPA’s failure to object is
    connected to the alleged procedural failing that Nucor challenges in this lawsuit, which
    is the agency’s failure to respond to Nucor’s petition for an objection. See WildEarth
    
    Guardians, 738 F.3d at 306
    (explaining that, to demonstrate causation in the
    procedural-injury context, “[a]ll that is necessary is to show that the procedural step
    was connected to the substantive result” (quoting 
    Massachusetts, 549 U.S. at 518
    )). In
    other words, if the EPA had reviewed and responded to Nucor’s petition in a timely
    fashion, it would also have had to object to Big River Steel’s permit in the event that it
    determined that Nucor “demonstrate[d] . . . that the permit is not in compliance with the
    [CAA.]” 42 U.S.C. § 7661d(b)(2). Therefore, it is undoubtedly the case that the
    procedural omission is “connected to” the substantive government action that directly
    causes Nucor’s alleged injury. See WildEarth 
    Guardians, 738 F.3d at 306
    .
    Nucor has likewise satisfied the relaxed standard for redressability that applies in
    cases raising procedural violations. Just as the landowner adjacent to a proposed dam
    does not need to demonstrate that requiring an agency to issue a statutorily required
    environmental impact statement will necessarily alter the substantive decision to build
    the dam, see Defs. of 
    Wildlife, 504 U.S. at 572
    n.7, Nucor need not demonstrate that
    requiring the EPA to respond to its petition will necessarily result in the EPA issuing an
    objection and blocking Big River Steel’s permit. In the procedural-injury context, it
    32
    suffices that the agency “might” do so, Lemon v. Green, 
    514 F.3d 1312
    , 1315 (D.C. Cir.
    2008), and as just mentioned, that possibility exists here.
    Accordingly, in light of the legal standards that apply to the standing
    determination when a plaintiff challenges an agency’s alleged procedural violation,
    Nucor’s PSD-increment injury is fairly traceable to the challenged conduct by the EPA
    and would likely be redressed by the relief that Nucor seeks.
    IV.    CONCLUSION
    Nucor has employed the CAA’s procedure for petitioning the EPA to object to a
    state-issued Title V permit, and has now filed a complaint in this Court that maintains
    that the agency has failed to grant or deny its petition within the required timeframe.
    Thus, the immediate subject of Nucor’s lawsuit is a mere procedural violation, but
    Nucor’s stake in the substantive outcome of this litigation is allegedly very real,
    because the Title V permit that is the subject of Nucor’s petition enables Big River
    Steel to operate a new steel mill just twenty miles away from Nucor’s two steel-
    manufacturing facilities. There is no dispute that all three plants are in the same county
    and in the same air quality control region, and Nucor alleges that it has pending
    construction plans at one of its preexisting mills that will require PSD review, and
    therefore will be meaningfully constrained by Big River Steel’s consumption of the
    applicable PSD increment for the region. For the reasons explained above, this Court
    concludes that, at this early stage of the litigation, Nucor has said enough to allege a
    concrete and particularized injury that is fairly traceable to the EPA’s failure to timely
    respond to Nucor’s petition, and that Nucor’s complaint contains sufficient facts to
    support a plausible claim that the injury Nucor faces (in the form of Big River Steel’s
    33
    consumption of the PSD-increment) is imminent and would likely be redressed by a
    favorable outcome.
    Accordingly, the allegations of Nucor’s complaint sufficiently support Nucor’s
    contention that it has standing to pursue the relief that it seeks in this lawsuit, which
    means that, as set forth in the accompanying order, the EPA’s motion to dismiss for
    lack of standing must be DENIED.
