BENTON, Circuit Judge.

       The City of Kennett, Missouri, sued the Environmental Protection Agency,
challenging the EPA’s approval of a total maximum daily load for Buffalo Ditch. The
district court granted summary judgment for the EPA. The City appeals. Having
jurisdiction under 28 U.S.C. § 1291, this court affirms in part, vacates in part, and
remands.
                                           I.

       The Clean Water Act requires, subject to EPA approval, states to establish
“water quality standards.” See 33 U.S.C. § 1313(a). Standards “shall consist of the
designated uses of the navigable waters involved and the water quality criteria for
such waters based upon such uses.” § 1313(c)(2)(A). States must review standards
at least once every three years and modify them “as appropriate.” § 1313(c)(1).

        To achieve water quality standards, the Act imposes “effluent limitations” under
sections 1311(b)(1)(A) and (B). An “effluent limitation” is “any restriction . . . on
quantities, rates, and concentrations of chemical, physical, biological, and other
constituents which are discharged from point sources into” certain waters. §
1362(11). A “point source,” is “any discernible, confined and discrete conveyance .
. . from which pollutants are or may be discharged”—e.g., a drainpipe at a wastewater
treatment plant. § 1362(14). But these effluent limitations may not be enough for all
waters. States must “identify those waters within its boundaries for which the effluent
limitations required by section 1311(b)(1)(A) and section 1311(b)(1)(B) of this title
are not stringent enough to implement any water quality standard applicable to such
waters.” § 1313(d)(1)(A). These are called “impaired waters.” See, e.g., Missouri
Soybean Ass’n v. EPA, 

, 511 (8th Cir. 2002) (referencing Missouri’s list
of “impaired waters”); Am. Farm Bureau Fed’n v. EPA, 

, 309 (3rd Cir.
2015) (“§ 1313(d) requires ‘impaired waters’ to be listed . . .”).

       For impaired waters, states shall establish, subject to EPA approval, “the total
maximum daily load” (TMDL) for certain pollutants. § 1313(d)(1)(C), (d)(2). “Such
load shall be established at a level necessary to implement the applicable water quality
standards with seasonal variations and a margin of safety . . . .” § 1313(d)(1)(C). The
TMDL calculates the impaired water’s “loading capacity”—the greatest amount of a
pollutant that can be introduced without violating water quality standards. 40 C.F.R.
§§ 130.2(e)-(i), 130.7(c). It allocates loading capacity between point sources and

                                          -2-
“nonpoint,” “natural background sources.” § 130.2(g)-(i). Allocations to point
sources are “wasteload allocations” and “constitute a type of water quality-based
effluent limitation.” § 130.2(g).

       TMDLs are implemented by a pollution permitting program. A “discharge of
any pollutant” must comply with specified provisions of the Act. 33 U.S.C. §
1311(a). See § 1362(12) (defining “discharge of a pollutant” as the “addition of any
pollutant” into certain waters). One specified provision is section 1342, which
establishes the National Pollution Discharge Elimination System (NPDES). § 1342.
Under NPDES, point-source operators obtain permits for discharge. 

have limits on discharge necessary to achieve water quality standards. 40 C.F.R. §
122.44(d)(1). “When developing water quality-based effluent limits under [section
122.44(d)(1)] the permitting authority shall ensure that . . . [e]ffluent limits developed
to protect [water quality criteria] are consistent with the assumptions and requirements
of any available wasteload allocation for the discharge prepared by the State and
approved by EPA . . . .” § 122.44(d)(1)(vii), (B). In other words, a permit for
discharge into an impaired water must have limits on discharge that are consistent
with the wasteload allocations in the TMDL.

       The EPA can issue permits, but states can—and Missouri does—administer
their own NPDES permit programs. § 1342(a)-(b). States must notify the EPA when
they intend to issue a permit. § 1342(d)(1). If the EPA objects that the permit is
“outside the guidelines and requirements” of the Act, “[n]o permit shall issue.” §
1342(d)(2). See 40 C.F.R. §§ 123.44 (“EPA review of and objections to State
permits”); 123.29 (“State permit programs shall provide that no permit shall be issued
when the Regional Administrator has objected in writing under § 123.44.”). Permits
issued by states must be for “fixed terms not exceeding five years.” § 1342(b)(1)(B).

                                           II.

       Buffalo Ditch is a stream that runs southwest into Arkansas from the City. The
City’s Wastewater Treatment Plant is a point source of pollutants into it. Parts of
Buffalo Ditch have been on Missouri’s EPA-approved list of impaired waters since
1994, due to low levels of dissolved oxygen (DO), which benefits aquatic life. The
water-quality criterion for DO in Missouri streams (with exceptions not relevant here)
is 5 mg/L. Parts of Buffalo Ditch have historically not met this criterion (had less than
5 mg/L DO).

      In 2001, with the EPA behind on establishing TMDLs, a court ordered it to
approve a TMDL for Buffalo Ditch by the end of 2010. Before then, Buffalo Ditch
had no TMDL. In 2009, Missouri published a draft TMDL, which identified the
Treatment Plant as the primary point source. The City submitted comments and
questions. Missouri responded, made adjustments, and submitted a final version to
the EPA. The EPA approved it in 2010.

       The final TMDL sets wasteload allocations for pollutants from the Treatment
Plant. These wasteload allocations are more stringent than the limits in the City’s
NPDES permit. For example, the City’s permit has limits of 65 mg/L of biochemical
oxygen demand and 110 mg/L of total suspended solids (both on a weekly-average
basis). The TMDL sets wasteload allocations for these two pollutants at 5 mg/L and
31 mg/L, respectively. The City’s permit was to expire in 2015.1



      1
         At oral argument in this court, the City said the 2010 permit had been
“continued” pending a new one. The EPA’s brief to this court says that after the
district court’s decision, Missouri proposed a permit, but the EPA objected on grounds
that it “did not appear to include wasteload effluent limitations that are consistent with
the assumptions and requirements of the TMDL.” According to the EPA, this
“interim objection” pauses its review until Missouri responds.

                                           -4-
      In its “Implementation Plan” for point sources, the TMDL says (emphasis
added):

      This TMDL will be implemented partially through permit action. . . .
      Wasteload allocations developed for this TMDL will be used to derive
      new effluent limits . . . . However, it is the intention of the [Missouri
      Department of Natural Resources] that prior to implementation of these
      wasteload allocations, either the department or the city will determine
      whether the dissolved oxygen criterion of 5 mg/L . . . is appropriate or
      if a site-specific dissolved oxygen criterion is required. . . . If it is
      determined that the current water quality criterion for dissolved oxygen
      is appropriate, the wasteload allocations from the TMDL will be
      implemented. If it is determined not to be appropriate, and a new
      dissolved oxygen criterion is promulgated, then new wasteload
      allocations will be calculated and implemented.

Despite this intention, the DO criterion and the TMDL have apparently not changed.

       The City sued, alleging three counts: (1) the EPA exceeded its authority in
approving the TMDL; (2) the EPA acted arbitrarily and capriciously; (3) the EPA
failed to provide the required notice and comment.2 The City asked the district court
to declare the TMDL unlawful, vacate it, remand it to the EPA, and enjoin its
enforcement.

     The district court ordered the parties to file cross-motions for summary
judgment, saying that “this case should be able to be resolved pursuant to dispositive
motions based on the administrative record that formed the basis of the administrative


      2
       In a fourth count, the City asked for relief pending review under 5 U.S.C. §
705. The district court did not address this request. Neither party raised the issue on
appeal. This count is waived. See Jenkins v. Winter, 

, 751 (8th Cir.
2008) (“Claims not raised in an opening brief are deemed waived.”). The district
court did not err in granting summary judgment on count four.

decision of EPA being challenged.” In support of its cross-motion, the City argued
for summary judgment on counts one and two, asserting that full implementation of
the TMDL would not bring Buffalo Ditch into compliance with the DO criterion
because of nonpoint pollution.

       In support of its cross-motion, the EPA argued that (1) the City waived counts
one and two by not raising its arguments in the administrative process; (2) the City
waived count three by failing to argue for summary judgment on it; (3) the City lacked
standing because a favorable decision would not redress its injury; and (4) it was
entitled to summary judgment on the merits.

      The district court granted summary judgment to the EPA. The court ruled that
standing and ripeness were lacking, because the City will suffer harm only if and
when the TMDL is implemented. The court did not address the EPA’s waiver or
merits arguments.

       This court reviews de novo standing and ripeness determinations, and grants of
summary judgment. Heglund v. Aitkin County, 

, 577 (8th Cir. 2017)
(standing); Missourians for Fiscal Accountability v. Klahr, 

, 796 (8th
Cir. 2016) (ripeness); First Dakota Nat’l Bank v. Eco Energy, 

, 617 (8th
Cir. 2018) (summary judgment). “This court may affirm summary judgment on any
grounds supported by the record.” Food Market Merch., Inc. v. Scottsdale Indem.
Co., 

, 786 (8th Cir. 2017) (internal quotation marks omitted).

                                         III.

        The EPA argues the City waived count three—inadequate notice and comment.
In its memorandum supporting summary judgment, the City did not mention or argue
for summary judgment on count three. Nor did its reply and surreply memos respond
to the EPA’s arguments for summary judgment on that count. “[F]ailure to oppose

                                         -6-
a basis for summary judgment constitutes waiver of that argument.” Satcher v. Univ.
of Arkansas at Pine Bluff Bd. of Trs., 

, 735 (8th Cir. 2009). The City
waived count three. The district court did not err in granting the EPA (and denying
the City) summary judgment on count three.

                                           IV.

       “[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, 

,
1547 (2016), quoting Lujan v. Defenders of Wildlife, 

, 560-61 (1992).
“[S]tanding is to be determined as of the commencement of the suit.” Nat’l Parks
Conservation Ass’n v. EPA, 

, 973 (8th Cir. 2014), quoting 

n.5. The party seeking judicial review has the burden of persuasion and,
at the summary judgment stage, must support each element by “set[ting] forth by
affidavit or other evidence specific facts.” Iowa League of Cities v. EPA, 

, 870 (8th Cir. 2013), quoting 

.

       The issue is whether the City has standing to bring counts one and two. The
City argues that (1) it will incur compliance costs when the TMDL is implemented;
(2) these costs are fairly traceable to the EPA’s approval of the TMDL; and (3) they
are likely to be redressed by a favorable decision. The second element—causation—is
met and not in dispute. See 

complying with limitations in EPA letters to
be implemented in NPDES permits are fairly traceable to the EPA’s promulgation of
the letters).

                                            A.

      “To establish injury in fact, a plaintiff must show that he or she suffered ‘an
invasion of a legally protected interest’ that is ‘concrete and particularized’ and ‘actual

                                           -7-
or imminent, not conjectural or hypothetical.’” 

, quoting

. The district court ruled that the City’s injury, relating to the
TMDL’s future implementation, is not imminent. “Although imminence is
concededly a somewhat elastic concept, it cannot be stretched beyond its purpose,
which is to ensure that the alleged injury is not too speculative for Article III
purposes—that the injury is certainly impending.” Clapper v. Amnesty Int’l USA,

, 409 (2013) (emphasis in original), quoting 

n.2.
“In future injury cases, the plaintiff must demonstrate that ‘the threatened injury is
certainly impending, or there is a substantial risk that the harm will occur.’” In re
SuperValu, Inc., 

, 769 (8th Cir. 2017) (some internal quotation marks
omitted), quoting Susan B. Anthony List v. Driehaus, 

, 2341 (2014).
“[P]ossible future injury” is insufficient. 

(emphasis in
original).

      The Iowa League of Cities case is controlling. There, the League challenged
EPA letters that it alleged imposed new limitations on the point-source discharge of
its member cities. Iowa 

. Federal law required
implementation of these limitations by NPDES permits. 

59. This court
held that the League had associational standing, which requires that one of its
members has standing:

      At least some members are currently operating under permits that allow
      them to utilize [certain methods of discharge] inconsistent with the EPA
      letters, which they must imminently rectify. . . . Moving into compliance
      will be costly. The league has therefore articulated an injury in fact.

      At the commencement of this suit, the City was operating under a permit that
allowed discharge inconsistent with the TMDL. The permit was set to expire in 13
months. Any new permit must contain more stringent limits on discharge, consistent
with the TMDL’s wasteload allocations for the Treatment Plant. Moving into

                                          -8-
compliance will be costly. In its brief, the EPA “does not question that the City may
eventually have to expend funds in connection with the TMDL,” nor “contest that the
expenditure of money to comply with [] final permit conditions established to
implement a TMDL generally is sufficient injury to support standing to challenge the
TMDL.” The City has established injury in fact. See Am. Farm 

(standing to challenge TMDL where “even if the TMDL does not cause injury
by itself, it will give way to requirements,” which will “cause compliance costs for
[the plaintiff], a classic injury-in-fact”).

       The district court relied on City of Dover v. EPA, 

, 106-14
(D.D.C. 2014). There, a group of cities challenged the EPA’s approval of a list of
impaired waters. The cities claimed that including certain waters on the list would
require permits with more stringent limits. 

The court found no injury in
fact, “because it is uncertain whether the permits they are issued in the future will
contain those limits . . . .” 

Including the waters did not “guarantee” more
stringent permits, the court said, because it would affect permits only “indirectly”
through a TMDL, due to “uncertainty surrounding the as-yet-unpromulgated TMDL.”

To the contrary, the EPA here has approved a TMDL that requires more
stringent limits for the City. The City is challenging that TMDL. But even to the
extent City of Dover is inconsistent, it is not persuasive authority for a different
outcome here.

      The City’s injury is certainly impending despite Missouri’s “intention,”
expressed in the TMDL, to review the DO criterion before implementing the TMDL.
Once approved by the EPA, the TMDL’s wasteload allocations are binding on future
permits unless the EPA approves a replacement TMDL. To say that the permit will
comply with the TMDL is not “conjectural.” Cf. 

(“[B]ecause § 1881a at most authorizes—but does not mandate or direct—the
surveillance that respondents fear, respondents’ allegations are necessarily
conjectural.” (emphasis in original)). At the commencement of this suit, about four
years after the EPA approved the TMDL, the DO criterion and the TMDL had not

                                         -9-
changed. The possibility that Missouri, with EPA’s approval, could promulgate a new
DO criterion and change the TMDL before implementation does not prohibit the City
from challenging it.

                                            B.

       For redressability, it must be “‘likely,’ as opposed to merely ‘speculative,’ that
[the City’s] injury will be redressed by a favorable decision.” Balogh v. Lombardi,

, 543 (8th Cir. 2016), quoting 

. Conceding that
“[t]he problem in this case is not injury-in-fact,” the EPA argues that the City has not
established redressability. The EPA emphasizes the City’s argument that the TMDL
is insufficient to bring about compliance with the DO criterion. According to the
EPA, “if [the City] prevailed on [its] claims and EPA addressed them on remand in
the manner advocated by the City, it would cost the City more money.”

        But the City does not seek a more stringent TMDL. It seeks to vacate the
EPA’s approval of the current one and remand it to the EPA. On remand, the EPA
and Missouri might address the TMDL’s deficiencies by making it more stringent.
This would likely result in the same or higher compliance costs for the City. But this
is not the only possibility. The City hopes that the EPA and Missouri will address the
DO criterion, which the City sees as the fundamental problem. According to the City,
5 mg/L DO is unattainable at Buffalo Ditch “regardless of any action or inaction on
the part of the City” and “even with drastic reductions to non-point source
contributions . . . .” In the TMDL, after all, Missouri questioned whether the DO
criterion was appropriate for Buffalo Ditch. A lower DO criterion would likely result
in lower compliance costs for the City.

        It is not clear which possibility is more likely. But if the City does not prevent
its injury, it will at least delay it. The delay would last at least until the EPA approves
a new TMDL, which may exceed the duration of the City’s permit(s). Redressability
is met where a favorable decision “avoids, or at least delays,” a regulatory burden.

(“Jurisdictional issues such as standing and ripeness are determined at the time the

      “Fitness rests primarily on whether a case would benefit from further factual
development . . . .” Iowa 

(internal quotations omitted). The
key issue here is whether the EPA lawfully approved the TMDL. This depends
primarily on the administrative record supporting the EPA’s decision. The EPA
proposes to delay review until the TMDL is actually implemented. But even assuming
the means of implementation are relevant, there is little dispute what they are. The
upcoming permit must implement the TMDL by imposing limits on discharge
consistent with the TMDL’s wasteload allocations for the City. This is not a situation
where “further factual development regarding the agency’s application of the [TMDL]
would aid our decision.” See 

Park

       “The hardship factor looks to the harm parties would suffer, both financially
and as a result of uncertainty-induced behavior modification in the absence of judicial
review.” 

League of Cities, this court explained that delaying review of
certainly impending regulatory burdens can cause harm:

      Although the EPA portrays the harm as lurking, if at all, on the distant
      horizon, the threatened harm is more immediate, and it is certainly not
      speculative. League members must either immediately alter their
      behavior or play an expensive game of Russian roulette with taxpayer
      money, investing significant resources in designing and utilizing
      processes that—if these letters are in effect new legislative rules—were
      viable before the publication of the letters but will be rejected when the
      letters are applied as written. . . . Postponing our review until the EPA
      has denied a permit application in accord with the letters renders a
      hardship on municipal water authorities, who already would have
      invested irretrievable funds into their applications.

(internal citation omitted).

       This applies here, where the City must make planning decisions based on the
TMDL’s wasteload allocations. See Am. Farm 

-94
(“Although the TMDL has yet to be incorporated into a state’s continuing planning
process and enforced against any individual plaintiff, members of the trade
associations will have reason to limit their discharge of pollutants in anticipation of
the TMDL’s implementation. . . . If there is something wrong with the TMDL, it is
better to know now than later.”). Cf. Reg’l Rail 

(“Where the
inevitability of the operation of a statute against certain individuals is patent, it is
irrelevant to the existence of a justiciable controversy that there will be a time delay
before the disputed provisions will come into effect.”). But cf. City of Dover, 36 F.

       The EPA emphasizes Missouri’s “intention” to review the DO criterion before
implementation of the TMDL. The EPA proposes delaying review, because
implementation is a “contingent future event[] that may not occur as anticipated, or
indeed may not occur at all.” See Kennedy v. Ferguson, 

, 1001 (8th Cir.
2012). But the expiration date of the City’s permit has passed, Missouri and the EPA
are developing a new permit, and the DO criterion has not changed. The chance of
a change in the TMDL before implementation does not warrant delay. Cf. City of
Arcadia v. EPA, 

, 1156-59 (N.D. Cal. 2003) (challenge to
TMDLs not ripe due to evidence that the permitting authority would “revisit the
TMDLs” and could “submit new TMDLs to EPA for review and potential approval
well before the compliance dates in the [] TMDLs” (emphasis added)), citing Ohio
Forestry Ass’n v. Sierra Club, 

, 735 (1998) (challenge to EPA action not
ripe, partly because “the possibility that further consideration will actually occur
before the Plan is implemented is not theoretical, but real”). This case is ripe. The
district court erred in granting the EPA summary judgment on counts one and two.

       The EPA argues that the City waived claims one and two by not raising its
arguments in the administrative process. Because it would be beneficial, this court
remands this argument to the district court for consideration in the first instance and,
if necessary, the merits of counts one and two. See Loftness Specialized Farm
Equip., Inc. v. Twiestmeyer, 

, 851 (8th Cir. 2014) (“When it would be
