UNITED STATES DISTRICT COURT
FOR THE DISTRICT OF COLUMBIA
GUNPOWDER RIVERKEEPER,
Plaintiff,
v. Civil Action No. 1:20-cv-02063-CJN
MICHAEL S. REGAN, Administrator of the
United States Environmental Protection
Agency, et al.,
Defendants.
MEMORANDUM OPINION
Plaintiff Gunpowder Riverkeeper challenges the Environmental Protection Agency’s
approval of Maryland’s proposed total maximum daily load of polychlorinated biphenyls for the
Gunpowder and Bird Rivers. See generally Compl. In Count 1 of its Complaint, Riverkeeper
alleges that the EPA failed to perform a nondiscretionary duty to disapprove Maryland’s
proposal, which Riverkeeper alleges failed to comply with the Clean Water Act. Id. ¶¶ 69–77.
In Count 2, Riverkeeper alleges that the EPA’s approval is arbitrary and capricious under the
Administrative Procedure Act, 5 U.S.C. § 706(2). Id. ¶¶ 78–92. The EPA moves to dismiss
Count 1 only, on the ground that the EPA does not have a nondiscretionary duty to reject
Maryland’s submission. See generally Defendant’s Motion for Partial Dismissal (“Defs.’
Mot.”), ECF No. 7. The Court agrees and grants Defendants’ Motion.
I. Background
Enacted “to restore and maintain the chemical, physical, and biological integrity of the
Nation’s waters,” the Clean Water Act establishes the basic structure for regulating the discharge
of pollutants into the waters of the United States. 33 U.S.C. § 1251(a). Under the Act’s
1
cooperative federalism scheme, states have primary responsibility for establishing water quality
standards, subject to EPA approval. See id. § 1313(c).
Once a state’s water quality standards are established, the state must identify the bodies
of water within its jurisdiction that fail to meet those standards and establish the total maximum
daily load of pollutants that can be introduced into each identified body of water. Id. §
1313(d)(1)(A), (C). States must then submit to the EPA a list (known as the 303(d) list) of those
bodies of water and a proposed total maximum daily load for each. Id. § 1313(d)(2). The EPA
then “either approve[s] or disapprove[s] such identification and load not later than thirty days
after the date of submission.” Id.
In 2006 and 2008, respectively, Maryland added the Gunpowder and Bird Rivers to the
state’s Section 303(d) list. In compliance with the Clean Water Act, the state developed a total
maximum daily load proposal for both rivers. Compl. ¶ 42. During the relevant public-
comment period, Riverkeeper objected to both proposals, arguing that Maryland did not include
all potential sources of polychlorinated biphenyls (“PCBs”), which are man-made organic
chemicals used in products and materials produced before 1979 that can cause a variety of
adverse health effects. Id. ¶ 60.1 Specifically, Riverkeeper complained that the proposed loads
failed to account for PCB contamination found in the rivers’ bottom sediment and failed to
consider earlier compliance with water quality standards. Id. Maryland ultimately submitted its
proposed total maximum daily loads without change to the EPA, which approved them without
addressing the concerns Riverkeeper raised. Id. ¶ 60–63.
Riverkeeper filed this complaint challenging the EPA’s approval of Maryland’s proposed
loads on two grounds. First, relying on the Clean Water Act’s citizen-suit provision—which

2
allows private plaintiffs to bring claims stemming from the agency’s failure to fulfill any
mandatory duty under the Act—Riverkeeper claims that the EPA failed to execute its
nondiscretionary duty to disapprove of a total maximum daily load that failed to meet the
requirements of the Act. Id. ¶ 70. Second, Riverkeeper claims that the EPA’s approval of
Maryland’s proposals constitutes an agency action that is “arbitrary, capricious, an abuse of
discretion, or otherwise not in accordance with law” and is “in excess of statutory jurisdiction,
authority, or limitations, or short of statutory right” within the meaning of the APA. Id. ¶ 79.
The EPA moves to dismiss Count 1 only, arguing that the statute does not create a
nondiscretionary duty to disapprove a state’s proposal and that a citizen-suit claim is an improper
vehicle to challenge the EPA’s approval. Defs.’ Mot. at 1–3.
II. Legal Standard
Rule 12(b)(1) of the Federal Rules of Civil Procedure provides for dismissal of an action
for lack of subject-matter jurisdiction. “Under Rule 12(b)(1), the plaintiff bears the burden of
establishing that the court has jurisdiction.” Sheppard v. United States, 640 F. Supp. 2d 29, 33
(D.D.C. 2009). Because sovereign immunity is jurisdictional in nature, “a claim barred by
sovereign immunity lacks subject matter jurisdiction and may be dismissed under a 12(b)(1)
motion.” Scruggs v. Bureau of Engraving & Printing, 200 F. Supp. 3d 78, 82 (D.D.C. 2016)
(quoting FDIC v. Meyer, 510 U.S. 471, 475 (1994)). “The plaintiff bears the burden of
establishing that sovereign immunity has been abrogated.” Id.
Rule 12(b)(6), in turn, provides for dismissal of an action for failure to state a claim upon
which relief can be granted. A motion under Rule 12(b)(6) “challenges the adequacy of a
complaint on its face, testing whether a plaintiff has properly stated a claim.” Davis v. Sarles,
134 F. Supp. 3d 223, 226 (D.D.C. 2015). Only allegations that are factual, and not mere legal
conclusions, are entitled to the assumption of truth. Ashcroft v. Iqbal, 556 U.S. 662, 679–80
3
(2009). To survive a motion to dismiss under Rule 12(b)(6), a complaint’s factual allegations,
accepted as true, must contain sufficient factual material to raise a plausible right to relief. Bell
Atlantic Corp. v. Twombly, 550 U.S. 544, 570 (2007).
III. Analysis
The Clean Water Act authorizes citizen actions against the EPA Administrator for the
failure “to perform any act or duty under this chapter which is not discretionary with the
Administrator.” 33 U.S.C. § 1365(a)(2). This citizen-suit provision constitutes a waiver of
sovereign immunity, 33 U.S.C. § 1365(a)(2), but waivers of sovereign immunity, of course, must
be “unequivocal” and are therefore “construed strictly in favor of the sovereign.” U.S. Dept. of
Energy v. Ohio, 503 U.S. 607, 615 (1992). “The sovereignty of the United States raises a
presumption against its suability, unless it is clearly shown; nor should a court enlarge its
liability to suit conferred beyond what the language requires.” Eastern Transp. Co. v. United
States, 272 U.S. 675, 686 (1927). Thus, “[a] clearly mandated, nondiscretionary duty imposed
on the Administrator is a prerequisite for federal jurisdiction under the [Clean Water Act] citizen
suit provision.” Miccosukee Tribe of Indians of Fla. v. EPA, 105 F.3d 599, 602 (11th Cir. 1997).
The Court may not enlarge the scope of the nondiscretionary duty beyond the statutory text. U.S.
Dept. of Energy v. Ohio, 503 U.S. 607, 615 (1992).
The language of the Act is clear. As relevant here, it provides: “Each State shall submit
to the Administrator . . . for his approval the waters identified and the loads established. The
Administrator shall either approve or disapprove such identification and loads not later than
thirty days after the date of submission.” 33 U.S.C. § 1313(d)(2) (emphasis added).2

“If the Administrator approves” the state’s submission, the state must incorporate the list of impaired bodies of
water and TMDL into its plan under the Act. 33 U.S.C. § 1313(d)(2). But “[i]f the Administrator disapproves” the
state’s submission, he must, within thirty days, identify the impaired bodies of water and establish their TMDL to be
incorporated under the state’s plan. Id.
4
This provision follows a “familiar and entirely sensible structure” containing both
discretionary and non-discretionary components. Sanitary Bd. of Charleston v. Wheeler, 918
F.3d 324, 332 (4th Cir. 2019). As for the latter, the statute imposes certain inflexible
requirements on the Administrator. She must, upon receipt of a state’s proposal, decide whether
to approve or disapprove that proposal. She must also make that decision within a certain
timeframe—thirty days of receiving the proposal.
The statute does not, however, dictate what the Administrator’s decision must be.
Instead, the decision itself—whether to approve or disapprove the submission—is left entirely to
the Administrator’s discretion. The Act uses conditional language when outlining the decision
before the Administrator and “provides no fixed criterion that clearly delineates when approval
[or disapproval] is required.” Sanitary Bd. of Charleston v. Wheeler, 918 F.3d 324, 332 (4th Cir.
2019). It leaves that decision to the scientific judgment of the agency. And such a decision, in
which an agency brings its own calculations and scientific expertise to bear, “is the ‘hallmark’ of
agency discretion.” Envtl. Def. Fund v. Thomas, 870 F.2d 892, 900 (2d Cir. 1989) (quoting
Kennecott Copper Corp. v. Costle, 572 F.2d 1349, 1354 (9th Cir. 1978)). The Administrator
does not, as Riverkeeper claims, have a “clearly mandated, nondiscretionary duty” to disapprove
a state’s proposal. See Miccosukee Tribe, 105 F.3d at 602.3 Without such a nondiscretionary
duty, this Court cannot exercise jurisdiction under the citizen suit provision. See id.
Other courts have reached similar results in analogous contexts. In Askins v. Ohio Dept.
of Agriculture, 809 F.3d 868 (6th Cir. 2016), for example, Plaintiffs claimed that the EPA was
required to “conduct a hearing whenever a State is not administering a program in accordance”
3
The relevant regulation mirrors the statute’s discretionary language concerning total maximum daily load approval
and imposes only an obligation to take some action on state submissions. See 40 C.F.R. § 130.7(d)(2). The Court
need not decide whether that regulation could itself provide the basis for a citizen suit because it does not create a
nondiscretionary duty to approve or disapprove a state’s submission. See 40 C.F.R. § 130.7(d)(2).

with certain statutory requirements, because the Act required that “whenever [the EPA]
determines after public hearing that a State is not administering a . . . program approved . . . [the
EPA] shall withdraw approval of such program.” Id. at 877. The Sixth Circuit held that the Act
required the EPA only to withdraw approval of a non-complying state program after a hearing
but did not impose on the EPA a nondiscretionary duty to conduct a hearing. Id. The Court
therefore concluded that it lacked jurisdiction to hear Plaintiffs’ citizen-suit claims. Id.
Other courts have rejected claims that the EPA had a nondiscretionary duty to approve or
disapprove state submissions like the ones at issue here. In Sanitary Board of City of Charleston
v. Wheeler, 918 F.3d 324 (4th Cir. 2019), for example, Plaintiff challenged the EPA’s denial of
its proposed water quality standards under the citizen-suit provision and argued that “the EPA
had no discretion to disapprove [its proposed water quality] standard,” which the EPA had
previously determined to be consistent with the statute. Id. at 327, 329. The Court held that the
EPA did not have a nondiscretionary duty to approve West Virginia’s water quality standards,
noting that when reaching a conclusion on the state’s proposed standards, “the substance of the
decision is left to the expertise of the agency and it can exercise its judgment as it sees fit, so
long as it does not refuse to exercise it altogether.” Id. at 331–33. As the Court put it, the Clean
Water Act imposes on the EPA “strict requirements . . . related to the timing and notification
procedures of a denial decision,” but the agency’s judgment to approve or disapprove a proposal
is “discretionary [even when its] timing is not.” Id. at 331–32.
Similarly, in Scott v. City of Hammond, Indiana, 741 F.2d 992 (7th Cir. 1984), the
plaintiff alleged that the EPA had a nondiscretionary duty to disapprove water quality standards
that fail to protect public health. Id. at 994. The Court held that “the content of water quality
standards cannot be ordinarily challenged through a citizen’s suit.” Id. at 995. The EPA had a
6
nondiscretionary duty to take some action by a date certain, but it did not have a
nondiscretionary duty to disapprove a state’s water quality standards that Plaintiff claimed to be
inadequate. Id. at 994–98.
A final note. Riverkeeper insists that Congress intended the Act’s citizen-suit provision
to provide a backstop for invalid state proposals regarding total maximum daily loads. Pl.’s
Opposition to Defendant’s Motion for Partial Dismissal (“Pl.’s Opp’n”), ECF No. 9, 5–6. That
intent, Riverkeeper argues, would be frustrated here if it were unable to challenge the adequacy
of Maryland’s proposals under the citizen-suit provision. Id. This argument is unpersuasive. In
addition to asking the Court to engage in the difficult task of divining the intent of a
multimember body such as Congress from something other than statutory text, Riverkeeper
ignores the fact that there are other avenues to challenge the EPA’s approval of state total
maximum daily loads—including the filing of an APA claim, which Riverkeeper itself asserts in
Count II of the Complaint. See Compl. ¶ 78–92. The APA provides an appropriate venue for
redress as it allows Riverkeeper to seek judicial review of whether the EPA permissibly
exercised its discretion in approving Maryland’s submissions. See Sierra Club v. Thomas, 828
F.2d 783, 792 (D.C. Cir. 1987) (indicating that the Clean Water Act’s citizen-suit provision is an
improper venue to challenge an EPA’s alleged abuse of discretion and noting that “we long ago
rejected . . . the convoluted notion that EPA is under a nondiscretionary duty—for purposes of
[the Clean Air Act citizen-suit provision]—not to abuse its discretion.”).4

Riverkeeper also argues that the constructive submission doctrine demonstrates that the Court possesses the power
to review Maryland’s allegedly noncompliant proposal. See Pl.’s Opp’n at 7. But that doctrine is inapplicable here,
as it “applies only where a state ‘clearly and unambiguously’ expresses a decision not to submit” total maximum
daily loads. Ohio Valley Environmental Coalition, Inc. v. Pruitt, 893 F.3d 225, 230 (2018) (quoting S.F. Bay
Keeper v. Whitman, 297 F.3d 877, 882 (2002)). Here, Maryland submitted its proposed loads and the EPA approved
them.

IV. Conclusion
In sum, Riverkeeper has failed to show that the EPA had a clearly mandated,
nondiscretionary duty to disapprove an allegedly invalid state total maximum daily load
proposal—a necessary prerequisite to bringing a citizen-suit under the Clean Water Act. The
Court therefore grants Defendants’ Motion for Partial Dismissal. A separate order will follow.
