UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA
JAMES FARMER, et al.,
Plaintiffs,
v. No. 24-cv-1654 (DLF) UNITED STATES ENVIRONMENTAL PROTECTION AGENCY, et al.,
Defendants.
MEMORANDUM OPINION
Plaintiffs James Farmer; Robin Alessi; Patsy Schultz; Karen Coleman; Tony Coleman;
Johnson County, Texas; Maine Organic Farmers and Gardeners Association; and Potomac
Riverkeeper, Inc. (“Plaintiffs”) bring this action against defendants the United States
Environmental Protection Agency (“EPA”) and EPA Administrator Michael S. Regan, alleging
that EPA has failed to identify and regulate sewage sludge pollutants in violation of the Clean
Water Act (“CWA”), 33 U.S.C. §§ 1251 et seq., and the Administrative Procedure Act (“APA”),
5 U.S.C. §§ 701–706. Before the Court is the National Association of Clean Water Agencies’
(“NACWA”) motion to intervene as a defendant under Rule 24(a). 1 Dkt. 20. NACWA’s motion
is opposed by the plaintiffs, but not by EPA. See Pls.’ Opp’n, Dkt. 24. For the reasons that follow,
the Court will grant NACWA’s motion.
1 In the alternative, NACWA moves for permissive intervention under Rule 24(b). Mot. to Int. at 21. Because this Court will conclude that NACWA may intervene as of right under Rule 24(a), it will not consider whether NACWA meets the requirements to intervene permissively. See Fund for Animals, Inc. v. Norton, 322 F.3d 728, 731 (D.C. Cir. 2003) (“Because we conclude that NRD is entitled to intervene as of right, we need not address the issue of permissive intervention.”). I. BACKGROUND
A. Factual Background
Sewage sludge is “solid, semi-solid, or liquid residue generated during the treatment of
domestic sewage in a treatment works.” 40 C.F.R. § 503.9(w). Section 405(d) of the CWA
governs the regulation of sewage sludge. Sections 405(d)(2)(A) and (B) require EPA to identify
toxic pollutants which may be present in sewage sludge in concentrations that may adversely affect
public health or the environment and to propose regulations specifying acceptable management
practices and establishing numerical limitations for such pollutants. 33 U.S.C. § 1345(d)(2)(A)–
(B). Section 405(d)(2)(C) requires EPA to review “not less often than every 2 years . . . the
regulations promulgated under this paragraph for the purpose of identifying additional toxic
pollutants and promulgating regulations for such pollutants consistent with the requirements of
this paragraph.” Id. § 1345(d)(2)(C). EPA completed its most recent review of its sewage sludge
regulations in December 2022. See 2020–2021 EPA Biosolids Biennial Rep. No. 9.
Per- and polyfluoroalkyl substances (“PFAS”) are a class of synthetic chemicals used in a
variety of consumer products and industrial applications. See Mot. to Int. at 10. Because of their
durability, PFAS are found in trace amounts throughout the world ecosystem, including in sewage
sludge. Id. “Public utilities are not designed to treat, remove, or destroy PFAS and have no readily
available treatment options for the trace amounts of PFAS in the many millions of gallons of
wastewater treated daily at a typical [publicly owned treatment work].” Id. Across its biennial
reports, EPA has identified eleven PFAS as being present in sewage sludge. Second Am. Compl.,
at ¶ 11, Dkt. 12. EPA has, as of the date of this order, not promulgated any regulations of PFAS
in sewage sludge, see 40 C.F.R. Part 503, but is conducting risk assessments for two PFAS, see
2 U.S. Env’t Prot. Agency, PFAS Strategic Roadmap: EPA’s Commitments to Action 2021–2024 at
16 (2021).
Plaintiffs comprise a group of farmers, the county in which they live and work, a nonprofit
organization dedicated to promoting organic agriculture, and an organization representing
members who reside throughout the Potomac River watershed. Second Am. Compl. at ¶¶ 21–38.
Intervenor-applicant NACWA is a national nonprofit organization that represents the interests of
over 350 public clean water agencies responsible for the treatment of wastewater and stormwater,
including sewage sludge, in accordance with EPA’s regulations. Mot. to Int. at 1–4.
B. Procedural Background
The plaintiffs allege that EPA has failed to (1) identify a set of eighteen PFAS as present
in sewage sludge in its most recent biennial report contrary to available information and (2)
regulate a set of eleven PFAS identified as present in sewage sludge in EPA’s various biennial
reports in violation of EPA’s non-discretionary duties under the CWA. Second Am. Compl. ¶¶ 3–
4 (citing 33 U.S.C. § 1354(d)); see id. ¶¶ 10–11. They further allege that each of these failures
constitute an arbitrary and capricious action and an agency action unlawfully withheld or
unreasonably delayed under the APA. Id. ¶ 4 (citing 5 U.S.C. § 706(1)–(2)(A)). The plaintiffs
seek, among other relief, an order directing EPA to regulate the eleven PFAS that EPA has
identified as present in sewage sludge. Id. at 31. On September 26, 2024, following the filing of
the plaintiffs’ second amended complaint, Dkt. 12, and EPA’s motion to dismiss, Dkt. 13,
NACWA filed the instant motion to intervene, Dkt. 20.
3 II. LEGAL STANDARDS
Rule 24 of the Federal Rules of Civil Procedure “outlines two different avenues by which
a court can allow an outsider to intervene—intervention of right, and permissive intervention.”
EEOC v. Nat’l Children’s Ctr., Inc., 146 F.3d 1042, 1044 (D.C. Cir. 1998). Rule 24(a) provides
for intervention of right when a movant can demonstrate four requirements: “1) timeliness of the
application to intervene; 2) a legally protected interest; 3) that the action, as a practical matter,
impairs or impedes that interest; and 4) that no party to the action can adequately represent the
potential intervenor’s interest.” Crossroads Grassroots Pol’y Strategies v. FEC, 788 F.3d 312,
320 (D.C. Cir. 2015) (citing Fed. R. Civ. P. 24(a)). Independently, under this circuit’s caselaw,
“to intervene under Rule 24(a), the movant must demonstrate that it has standing under Article III
of the U.S. Constitution.” Yocha Dehe v. United States Dep’t of the Interior, 3 F.4th 427, 430
(D.C. Cir. 2021). 2 “Courts are to take all well-pleaded, nonconclusory allegations in the motion
2 In Town of Chester v. Laroe Estates, Inc., 581 U.S. 433 (2017), the Supreme Court pronounced that “an intervenor of right must have Article III standing in order to pursue relief that is different from that which is sought by a party with standing.” 581 U.S. at 440; see also Va. House of Delegates v. Bethune-Hill, 587 U.S. 658, 663 (2019) (intervenor-defendant need not demonstrate standing so long as it is not “invoking a court’s jurisdiction”); Little Sisters of the Poor Saints Peter & Paul Home v. Pennsylvania, 591 U.S. 657, 674 n. 6 (2020) (intervenor-defendant did not need to demonstrate standing when it sought the same relief as the defendant-appellant). Even so, subsequent D.C. Circuit precedent requires intervenors of right to demonstrate Article III standing regardless of whether they invoke the court’s jurisdiction or seek relief different from that sought by the original parties. See Yocha Dehe, 3 F.4th at 430–32 (D.C. Cir. 2021). Consequently, some judges in this district have continued to require all intervenors of right to demonstrate Article III standing, while others have not. Compare, e.g., Signal Peak Energy, LLC v. Haaland, No. 24-cv- 366 (TSC), 2024 WL 3887386, at *3–4 (D.D.C. Aug. 21, 2024) (noting the tension between Yocha Dehe and Little Sisters but concluding that the court is bound by circuit precedent to require all intervenors of right to demonstrate Article III standing) with Env’t Integrity Project v. Wheeler, No. 20-cv-1734 (KBJ), 2021 WL 6844257, at *2 (D.D.C. Jan. 27, 2021) (Jackson, J.) (defendant- intervenors not invoking the court’s jurisdiction are not required to demonstrate standing) and Childs.’ Health Def. v. CDC, No. 23-cv-431 (TNM), 2024 WL 3521593, at *5 n.3 (D.D.C. July 24, 2024) (same). This Court need not decide this issue because NACWA has associational Article III standing.
4 to intervene, the proposed complaint or answer in intervention, and declarations supporting the
motion as true absent sham, frivolity or other objections.” Wildearth Guardians v. Salazar, 272
F.R.D. 4, 9 (D.D.C. 2010) (quoting Sw. Ctr. for Biological Diversity v. Berg, 268 F.3d 810, 820
(9th Cir. 2020)).
III. ANALYSIS
A. Standing
An organization has standing to bring suit on behalf of its members when “(a) its members
would otherwise have standing to sue in their own right; (b) the interests it seeks to protect are
germane to the organization’s purpose; and (c) neither the claim asserted nor the relief requested
requires the participation of individual members in the lawsuit.” Hunt v. Wa. State Apple Advert.
Comm’n, 432 U.S. 333, 343 (1977). An organization’s members have standing to sue in their own
right when they can demonstrate that they would suffer an “injury in fact” that is “(a) concrete and
particularized” and “(b) actual or imminent, not conjectural or hypothetical.” Lujan v. Defs. of
Wildlife, 504 U.S. 555, 560–61 (1992) (cleaned up). They must also establish that there is “a
causal connection between the injury and the conduct complained of” and that it is “likely, as
opposed to merely speculative, that the injury will be redressed by a favorable decision.” Id.
(cleaned up).
NACWA has demonstrated that its members would have standing to sue in their own right.
Presently, EPA does not regulate PFAS in sewage sludge. Mot. to Int. at 12. Should the plaintiffs’
suit prove successful, however, EPA would be required to promulgate new regulations concerning
PFAS in sewage sludge. That, in turn, would entail “the imposition of new numerical limitations,
management practice, and/or operational standards which have associated costs” for NACWA’s
members. NACWA Reply, at 6, Dkt. 25; see also Mot. to Int. at 17 (“The regulation of any new
5 substance (let alone multiple substances) under Part 503 will change NACWA members’
management of biosolids. Imposing pollutant limits for PFAS under Part 503 will alter NACWA
members’ existing disposal options, entail sampling and monitoring costs, and potentially require
costly operational changes.”); 33 U.S.C. § 1345(d)(2)(A)(i) (“[T]he Administrator shall . . .
propose regulations specifying acceptable management practices for sewage sludge containing
each such toxic pollutant and establishing numerical limitations for each such pollutant.”).
Because the successful disposition of the plaintiffs’ suit would necessarily result in the
promulgation of new regulations with associated economic harms to NACWA’s members,
NACWA has sufficiently alleged an injury fairly traceable to the plaintiffs’ requested relief and
redressable by a judicial decision denying such relief. See County of San Miguel. v. MacDonald,
244 F.R.D. 36, 44–45 (D.D.C. 2007) (finding that intervenor-applicants had standing to intervene
when plaintiffs sought issuance of an emergency rule listing a bird species as endangered because
such rule would lead to greater regulation of intervenor-applicants’ members’ land with associated
financial costs); cf. Fund for Animals, 322 F.3d at 733–74 (holding that when a party or a party’s
property is the direct object of an agency action, standing is self-evident).
The plaintiffs argue that any injury resulting from such regulations is too speculative to
support Article III standing because they do not request that the Court specify the content of any
new regulations. 3 See Pls.’ Opp’n at 6–9, 7 n.3. But the cases that the plaintiffs cite are readily
3 The Court notes that the plaintiffs did not brief the issue of standing because they take the position that intervenor-defendants that do not invoke a court’s jurisdiction need not demonstrate it. See Pls.’ Opp’n at 7. Rather, the plaintiffs raise this argument in the context of Rule 24’s interest prongs. See id. at 5–7. However, “[c]ourts in this circuit generally treat the standing analysis for intervention as of right as equivalent to determining whether the intervenor has a ‘legally protected’ interest under Rule 24(a).” Biden v. IRS, No. 23-cv-2711 (RC), 2024 WL 4332072, at *10 n.8 (D.D.C. Sep. 27, 2024); see Crossroads, 788 F.3d at 320 (“[S]ince Crossroads has constitutional standing, it a fortiori has an interest relating to the property or transaction which is
6 distinguishable. In Environmental Integrity Project, the court found that intervenor-applicants
lacked standing to challenge a consent decree that required EPA “to initiate a rulemaking and to
issue whatever regulations that it, in its discretion, deems necessary” because the consent decree
“would not in any way dictate the rule’s content, nor prevent the EPA from declining to promulgate
a new rule at all.” 319 F.R.D. at 13–14. In those circumstances, injury was too speculative because
the consent decree gave EPA discretion not to promulgate any regulations at all. See id; see also
Defs. of Wildlife, 714 F.3d at 1324 (“Significantly, the consent decree does not require EPA to
promulgate a new, stricter rule. Instead, it merely requires that EPA conduct a rulemaking and
then decide whether to promulgate a new rule—the content of which is not in any way dictated by
the consent decree—using a specific timeline.” (emphasis in original)); Idaho Conservation
League, 811 F.3d at 514 (same). Here, in contrast, the plaintiffs request the Court to order EPA to
regulate certain PFAS in sewage sludge. See Second Am. Compl. at 31; Pls.’ Opp’n at 7 n.3. If
the Court were to grant the requested relief, EPA would be required to promulgate regulations.
That EPA would retain discretion as to the substance of any new rule is irrelevant because any
regulation of a new substance in sewage sludge would necessarily impose costs on NACWA’s
members because they would have to alter the way they presently manage sewage sludge. See
Mot. to Int. at 17. NACWA’s members thus have Article III standing to intervene in their own
right.
the subject of the action.” (cleaned up)); Roeder v. Islamic Republic of Iran, 333 F.3d 228, 233 (D.C. Cir. 2003) (“With respect to intervention as of right in the district court, the matter of standing may be purely academic… [A]ny person who satisfies Rule 24(a) will also meet Article III’s standing requirement.”). To support their argument, the plaintiffs also rely primarily on cases discussing standing. See Pls.’ Opp’n at 7 (citing Env’t Integrity Project v. McCarthy, 319 F.R.D. 8, 10 (D.D.C. 2016)); Defs. of Wildlife v. Perciasepe, 714 F.3d 1317, 1324–25 (D.C. Cir. 2013); In re Idaho Conservation League, 811 F.3d 502, 506–14 (D.C. Cir. 2016)). Accordingly, the Court considers the plaintiffs’ arguments in its standing analysis.
7 The other two requirements of associational standing are easily met here. NACWA “is a
national non-profit trade association representing the interests of over 350 public clean water
agencies managing wastewater and stormwater across the country,” Mot. to Int. at 1, and the
organization regularly solicits its members’ views on the matter of PFAS in sewage sludge and
conveys those views to EPA as it considers potential regulations, see Decl. of Adam Krantz, at 4,
Dkt. 20-3. Protecting the interests of NACWA’s members in avoiding undue adverse regulations
is clearly germane to NACWA’s organizational purpose. And because this litigation concerns
EPA’s compliance with the requirements of the CWA, and not any individualized grievances,
participation by NACWA’s members is unnecessary. See Int’l Dark-Sky Assoc. v. FCC, 106 F.4th
1206, 1218 (D.C. Cir. 2024). Accordingly, NACWA has demonstrated that it has associational
standing to intervene in this action.
B. Intervention of Right
Turning to the intervention requirements under Rule 24(a), the Court concludes each is met
here. The plaintiffs do not challenge the timeliness of the motion to intervene. See Pls.’ Opp’n at
3. And because the motion was filed before this Court issued any merits decision, intervention
would not unduly disrupt this litigation. See Roane v. Leonhart, 741 F.3d 147, 151 (D.C. Cir.
2014) (“[T]he requirement of timeliness is aimed primarily at preventing potential intervenors
from unduly disrupting litigation, to the unfair detriment of the existing parties.”); Waterkeeper
All., Inc. v. Wheeler, 330 F.R.D. 1, 6 (D.D.C. 2018) (finding a motion to intervene to be timely
when it was filed in advance of the court issuing any merits decisions). Further, because NACWA
possesses Article III standing, it necessarily has a legally protected interest in this litigation. See
Crossroads, 788 F.3d at 320; Fund for Animals, 322 F.3d at 735.
8 Disposition of this action also may impair NACWA’s ability to protect its interest in
avoiding undue adverse regulations. In assessing whether a movant’s interests may be impaired
by the outcome of a lawsuit, courts look to the “practical consequences of denying intervention,
even where the possibility of future challenge to the regulation remain[s] available.” Fund for
Animals, 322 F.3d at 735 (cleaned up). “[D]isposing of [an] action may as a practical matter impair
or impede a proposed intervenor’s interests when the disposition of the action would result in a
substantial change in the status quo with respect to those interests.” District of Columbia v.
Potomac Elec. Power Co., 826 F. Supp. 2d 227, 234 (D.D.C. 2011) (cleaned up). As discussed
supra, EPA does not presently regulate PFAS in sewage sludge. Importantly, both EPA and
NACWA maintain that the determination of whether PFAS are toxic substances that must be
regulated under statute is a matter for the agency’s discretion. See EPA Mot. to Dismiss, at 7, Dkt.
13; NACWA Mot. to Join, at 3, Dkt. 20-5. A ruling granting the plaintiffs’ requested relief would
deny EPA that discretion by requiring it to identify and regulate certain PFAS as toxic substances
under the CWA. See Second Am. Compl. at 31. That would plainly constitute a change to the
status quo because it would render the prospect of new regulations on sewage sludge—and the
associated economic costs to NACWA’s members—unavoidable. See Env’t Integrity Project,
2021 WL 6844257, at *3; County of San Miguel, 244 F.R.D. at 47. Even if NACWA could later
challenge such regulations in a separate litigation, “there is no question that the task of
reestablishing the status quo if the [plaintiffs] succeed[] in this case will be difficult and
burdensome.” Fund for Animals, 322 F.3d at 735. NACWA has demonstrated that the disposition
of this lawsuit may, as a practical matter, impair its ability to protect its interests.
Finally, EPA may not adequately represent NACWA’s interests in this litigation. To
satisfy the adequacy-of-representation requirement, a movant need only show “that representation
9 of his interest ‘may be’ inadequate; and the burden of making that showing should be treated as
minimal.” Trbovich v. United Mine Workers of Am., 404 U.S. 528, 538 n.10 (1972); see also
Dimond v. District of Columbia, 792 F.2d 179, 192 (D.C. Cir. 1986) (describing the adequacy-of-
representation requirement as “not onerous”). The D.C. Circuit has “often concluded that
governmental entities do not adequately represent the interests of aspiring intervenors.” Fund for
Animals, 322 F.3d at 736 & n.9 (collecting cases). That is because “government entities are usually
charged with ‘represent[ing] the interests of the American people,’ whereas aspiring intervenors,
like the intervenor-applicants here, are dedicated to representing their personal interests or the
interests of their members or members’ businesses.” County of San Miguel, 244 F.R.D. at 48
(quoting Fund for Animals, 322 F.3d at 736). NACWA points out that it “has both operational
and financial interests that EPA does not share. NACWA members remain directly responsible
for processing, treating, and otherwise managing PFAS in biosolids, whereas EPA does not.”
NACWA Reply at 8. While EPA and NACWA may be generally aligned in seeking dismissal of
the plaintiffs’ suit, “the tactical similarity of the present legal contentions of the parties does not
assure adequacy of representation or necessarily preclude the intervenor from the opportunity to
appear in its own behalf.” Fund for Animals, 322 F.3d at 737 (quoting Nuesse v. Camp, 385 F.2d
694, 703 (D.C. Cir. 1967)) (cleaned up). Because NACWA seeks to vindicate its members’ narrow
financial interests—as opposed to the general public interest that EPA is tasked with
representing—it meets the adequacy-of-representation requirement. Id. at 736–37; Env’t Integrity
Project, 2021 WL 6844257, at *3.
Accordingly, NACWA is entitled to intervene in this suit as of right under Rule 24(a). See
Fed. R. Civ. P. 24(a).
10 C. Restrictions on Intervention
“Even where the Court concludes that intervention as a matter of right is appropriate, its
inquiry is not necessarily at an end: district courts may impose appropriate conditions or
restrictions upon the intervenor’s participation in the action.” Forest Cnty. Potawatomi Cmty. v.
United States, 317 F.R.D. 6, 15 (D.D.C. 2016) (citing Fund for Animals, 322 F.3d at 737 n.11).
“[T]he primary limitation on the district court’s discretion is that any conditions imposed should
be designed to ensure the fair, efficacious, and prompt resolution of the litigation.” Wildearth
Guardians, 272 F.R.D. at 20.
The plaintiffs seek various restrictions on NACWA’s intervention, including not allowing
it to file a motion to join EPA’s motion to dismiss. See Pls.’ Opp’n at 13. While the Court
recognizes the plaintiffs’ concerns regarding additional briefing, NACWA’s motion to join raises
no new arguments. See NACWA Mot. to Join. Thus, the Court will allow NACWA to file its
motion and permit the plaintiffs to respond. The Court will also require NACWA (1) to continue
confining its arguments to the existing claims in the action and refrain from raising new claims or
collateral issues; and (2) to meet and confer with EPA prior to the filing of any motion, responsive
filing, or brief to determine whether its positions may be set forth in a consolidated fashion, with
any separate filings by NACWA including a certificate of compliance with this requirement and a
brief description of the need for separate filings. See Ctr. for Food Safety v. EPA, No. 23-cv-1633
(CKK), 2024 WL 1299338, at *5 (D.D.C. Mar. 26, 2024). The Court will address any additional
concerns, including requests to modify the page limitations on filings in LCvR 7(e), if they arise
during this litigation.
11 CONCLUSION
For the foregoing reasons, the Court will grant NACWA’s Motion to Intervene, Dkt. 20.
A separate order consistent with this decision accompanies this memorandum opinion.
