Appeal from the United States District Court
for the Northern District of California
Richard Seeborg, Chief District Judge, Presiding
Argued and Submitted March 6, 2025
San Francisco, California
Before: WARDLAW, PAEZ, and LEE, Circuit Judges.
The Clean Water Act (CWA) authorizes citizens to sue to enforce the statute.
*
This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.
See 33 U.S.C. § 1365(a). But the statute also aims to avoid burdening the federal
courts with unnecessary citizen suits. Cf. Hallstrom v. Tillamook Cnty., 493 U.S.
20, 29 (1989). To balance these goals, the CWA requires citizens to provide a
reasonably specific notice of alleged violations to the government at least sixty days
before suing, which allows the agency to take corrective action before a suit is filed.
33 U.S.C. § 1365(b); see Ctr. For Biological Diversity v. Marina Point Dev. Co.,
566 F.3d 794, 800–01 (9th Cir. 2009).
Here, the district court dismissed the lawsuit filed by Our Children’s Earth
Foundation and Ecological Rights Foundation (together, “OCE”), ruling that OCE
had failed to send an adequate pre-suit notice before suing. We review de novo and
affirm the dismissal. See id. at 799.
In November 2023, OCE sent a pre-suit notice letter to the Administrator of
the U.S. Environmental Protection Agency (“EPA”), alleging that the EPA had not
published and annually revised “a list of all applicable water quality standards as
required by . . . 33 U.S.C. § 1314(a)(6).” 1 See also 33 U.S.C. §§ 1365(a)(2),
1365(b)(2). But OCE’s description of the alleged failure was ambiguous: “[t]he
1
“The Administrator shall, within three months after December 27, 1977, and
annually thereafter, for purposes of section 1311(h) of this title publish and revise as
appropriate information identifying each water quality standard in effect under this
chapter or State law, the specific pollutants associated with such water quality
standard, and the particular waters to which such water quality standard applies.” 33
U.S.C. § 1314(a)(6).
2 24-3735
water quality standard list You have last published is incomplete, substantially out
of date and inaccurate . . . .” Cf. 40 C.F.R. § 135.3(b). OCE later filed its citizen
suit in the Northern District of California.
The district court dismissed OCE’s complaint without prejudice, holding that
its pre-suit notice “ultimately failed to inform Defendants about their purported
violations.” This was because OCE argued that the last published “list” was flawed
“while simultaneously failing to specify to which list it [was] referring.” OCE
mistakenly believed that the EPA was relying on lists from 1978 and 1982 to comply
with § 1314(a)(6). Meanwhile, the EPA’s position was that its website provides the
information necessary to comply with § 1314(a)(6). But OCE did not mention the
1978 or 1982 lists in its pre-suit notice, and it only later learned of the EPA’s position
regarding its website. “The clear ambiguity in what Plaintiffs meant versus what
Defendants understood by the ‘last published’ list means there was a fundamental
misunderstanding such that Defendants would not be able to abate the alleged
violation.” Therefore, the district court ruled that OCE’s notice lacked “reasonable
specificity” for purposes of 33 U.S.C. § 1365(b), see 40 C.F.R. § 135.3(b), and
dismissed the case.
We affirm the dismissal because OCE’s pre-suit notice did not reasonably
specify what water quality standard information was flawed or erroneous. Having
chosen to identify a “list,” OCE should have at minimum described with reasonable
3 24-3735
specificity to what they were referring so that the EPA could make any necessary
corrections and avert a possible lawsuit. Otherwise, the EPA would be deprived of
the opportunity to take corrective measures to come into compliance with
§ 1314(a)(6). See Sw. Ctr. for Biological Diversity v. U.S. Bureau of Reclamation,
143 F.3d 515, 522 (9th Cir. 1998) (“At a minimum, however, Southwest was
obligated to provide sufficient information of a violation so that the Secretary of
Reclamation could identify and attempt to abate the violation.”). Because the notice
did not specify which “list” was flawed, OCE’s pre-suit notice failed to inform the
EPA about their purported violations under the CWA, and the suit must be
dismissed.
The statutory structure of the Clean Water Act underscores the integral role
of the pre-suit notice. By allowing citizen suits, Congress wanted private citizens to
ensure that the EPA lived up to its statutory obligations. 33 U.S.C. § 1365(a); see
Gwaltney of Smithfield, Ltd. v. Chesapeake Bay Found., Inc., 484 U.S. 49, 60 (1987).
But that statutory goal was balanced by a pre-suit notice requirement that encouraged
dialogue and non-litigation resolutions. See 33 U.S.C. § 1365(b). In other words,
Congress did not want private parties to race to the courthouse, incur substantial
costs, and then seek attorney’s fees from the taxpayers—if the parties could resolve
the problem without such costs. See Hallstrom, 493 U.S. at 29. A sufficiently
detailed pre-suit notice could have helped to ensure compliance without litigation
4 24-3735
costs in this case.
AFFIRMED.
