UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA
CENTER FOR WATER SECURITY AND COOPERATION,
Plaintiff,
v. Civil Action No. 23 - 2529 (LLA)
U.S. ENVIRONMENTAL PROTECTION AGENCY,
Defendant.
MEMORANDUM OPINION
The Center for Water Security and Cooperation (“CWSC”) brought this action against the
Environmental Protection Agency (“EPA” or “Agency”) alleging violations of the Freedom of
Information Act (“FOIA”), 5 U.S.C. § 552. CWSC claims that the EPA unlawfully withheld
records relating to the Agency’s enforcement of the Clean Water Act, 33 U.S.C. § 1251 et seq.
After resolving most of the disputes in this matter, the parties have now filed cross-motions for
summary judgment. For the reasons explained below, the court will grant the EPA’s motion for
summary judgment and deny CWSC’s cross-motion for summary judgment.
I. FACTUAL BACKGROUND
When municipal discharges into bodies of water run afoul of the Clean Water Act, the EPA
tries to bring the municipality into compliance “as soon as practicable.” Off. of Water, U.S. Env’t
Prot. Agency, Proposed 2022 Clean Water Act Financial Capability Assessment Guidance (“Guidance”) at 5 (Feb. 2022), https://perma.cc/5D49-TFRN.1 To determine how long the
compliance process should take, the EPA considers a variety of factors. Id. For example, the EPA
uses a Financial Capability Assessment (“FCA”) to evaluate “a community’s financial capability
as a part of negotiating implementation schedules under . . . enforcement agreements.” Id. These
analyses “provide an important benchmark for EPA decision-makers to consider in [Clean Water
Act] permitting and enforcement actions to support consistency across the country.” Id. at 7. Since
1997, the EPA has used FCAs “to support consent decree negotiations with over 100 wastewater
utilities throughout the United States and U.S. territories.” Id. Relevant to this litigation, the EPA
secured at least seven consent decrees between 2017 and 2020 against municipalities accused of
violating the Clean Water Act (“Consent Decree Cases”). See United States v. City of Corpus
Christi, No. 20-CV-235 (S.D. Tex. 2020); United States v. City of Hattiesburg, No. 20-CV-158
(S.D. Miss. 2020); United States v. City of Manchester, No. 20-CV-762 (D.N.H. 2020); United
States v. City of Houston, No. 18-CV-3368 (S.D. Tex. 2019); United States v. City of Meridian,
No. 19-CV-427 (S.D. Miss. 2019); United States v. City of Middletown, No. 18-CV-90 (S.D. Ohio
2018); United States v. Sanitary District of Hammond, No. 17-CV-48 (N.D. Ind. 2017).
In February 2022, the EPA proposed updated guidance concerning its use of FCAs in
enforcing provisions of the Clean Water Act. See generally Guidance. Two months later,
CWSC—“an independent, non-partisan and not-for-profit corporation” that “seeks to . . .
guarantee water security and universal access to water and sanitation around the world,” ECF No. 1
1 The court may take judicial notice “of public records and government documents available from reliable sources.” United States ex rel. Riedel v. Bos. Heart Diagnostics Corp., 332 F. Supp. 3d 48, 56 n.2 (D.D.C. 2018) (quoting Johnson v. Comm’n on Presidential Debates, 202 F. Supp. 3d 159, 167 (D.D.C. 2016)).
2 ¶ 19—submitted a FOIA request for information related to the Agency’s use of FCAs, ECF
No. 32-1 ¶ 1; ECF No. 33-1, at 1.2 Specifically, CWSC requested two categories of documents:
(a) “any and all Financial Capability Assessments analyses and any other relevant analyses, reports, reviews, or additional assessments performed or created that were used to inform or determine the implementation schedule and deadlines for implementing control measures or completing projects under the consent decree and Long Term Control Plans” for the “seven consent decrees” issued in the [Consent Decree Cases, and]
(b) “any and all written reports, analyses, or other assessments of FCA ‘consistency’ and ‘benchmark[ing].’”
ECF No. 32-1 ¶ 2; see ECF No. 33-1, at 1-2, 34-37. In September 2022, the EPA partially denied
the FOIA request by invoking FOIA Exemptions 5, 6, and 7(a). ECF No. 33-1, at 6, 39-42; ECF
No. 35-1 ¶ 2.
The EPA thereafter provided CWSC with several responsive documents and multiple
Vaughn Indices explaining its withholdings. ECF No. 33-1, at 6, 22; ECF No. 35-1 ¶¶ 3-4. At the
end of December 2022, CWSC appealed the EPA’s FOIA decision. ECF No. 33-1, at 18-104. In
January 2023, the EPA partially granted the appeal but largely upheld the Agency’s invocation of
various FOIA Exemptions. ECF No. 32-3, at 24-27.
II. PROCEDURAL HISTORY
In August 2023, CWSC filed this action against the EPA seeking to compel the EPA to
conduct a more thorough search and disclose all responsive records (and portions of records) being
withheld under FOIA. ECF No. 1, at 12. The parties met and conferred and filed a series of status
reports updating the court on their efforts to narrow the case. See ECF Nos. 19 to 21, 23, 24, 26
2 Citations to ECF No. 33-1 refer to the ECF-generated page numbers, rather than the document’s internal pagination.
3 to 30. During that time, the EPA made additional productions of previously withheld records and
provided information to contextualize its other withholdings. ECF No. 32-3 ¶ 26. Eventually, the
parties whittled their dispute down to 179 records that were released with redactions and 119
records that were withheld in full under FOIA Exemption 5. Id.; ECF No. 30 ¶ 2. Unable to
further resolve their disagreements, the EPA filed a motion for summary judgment in
December 2024 and argued that it (1) had conducted an adequate search for records; (2) had
properly withheld records under FOIA Exemption 5; and (3) had properly segregated non-exempt
information for disclosure. ECF No. 32. CWSC filed a cross-motion for summary judgment in
January 2025. ECF No. 33. Both motions are now fully briefed. ECF Nos. 32, 33, 35, 38.
In the process of briefing summary judgment, the parties further narrowed the scope of
their disputes. First, while CWSC originally sought responsive records for both parts of its original
FOIA request, see supra Part I, it later agreed to withdraw its request for the first category of
documents, see ECF No. 38, at 1 (“Records regarding the first part of the FOIA Request are no
longer at issue.”). Second, CWSC abandoned its challenge to the adequacy of the EPA’s search.
Compare ECF No. 33, at 8-9, with ECF No. 38. Third, CWSC dropped its claim that the EPA’s
Vaughn Index was insufficiently detailed, particularly with respect to authorship, recipient, and
confidentiality information. Compare ECF No. 33, at 9-17, with ECF No. 38.
III. LEGAL STANDARD
“[T]he vast majority of FOIA cases can be resolved on summary judgment.” Brayton v.
Off. of the U.S. Trade Representative, 641 F.3d 521, 527 (D.C. Cir. 2011). Summary judgment
may be awarded to the agency if it can demonstrate that no material facts are in dispute, that it
conducted an adequate search for responsive records, and that each record has either been produced
or is exempt from disclosure. Jud. Watch, Inc. v. U.S. Dep’t of Homeland Sec., 59 F. Supp. 3d
4 184, 189 (D.D.C. 2014). The agency invoking a FOIA exemption bears the burden of
demonstrating that it applies. U.S. Dep’t of Just. v. Reps. Comm. for Freedom of the Press, 489
U.S. 749, 755 (1989). This burden is met when agency affidavits or declarations “describe the
justifications for nondisclosure with reasonably specific detail, demonstrate that the information
withheld logically falls within the claimed exemption, and are not controverted by either contrary
evidence in the record nor by evidence of agency bad faith.” Larson v. Dep’t of State, 565 F.3d
857, 862 (D.C. Cir. 2009) (quoting Miller v. Casey, 730 F.2d 773, 776 (D.C. Cir. 1984)). The
agency may also carry its burden “by providing the requester with a Vaughn index, which must
adequately describe each withheld document, state which exemption the agency claims for each
withheld document, and explain the exemption’s relevance.” Johnson v. Exec. Off. for U.S. Att’ys,
310 F.3d 771, 774 (D.C. Cir. 2002).
Even where the requested information falls comfortably within a FOIA exemption, the
agency must still demonstrate that disclosure would result in foreseeable harm. 5 U.S.C.
§ 552(a)(8). To satisfy this burden, the agency must “articulate both the nature of the harm [from
release] and the link between the specified harm and specific information contained in the material
withheld.” Reps. Comm. for Freedom of the Press v. Fed. Bureau of Investigation, 3 F.4th 350,
369 (D.C. Cir. 2021) (alteration in original) (quoting H.R. Rep. No. 114-391, at 9 (2016)). The
agency must come up with more than “‘generalized assertions’” or “‘speculative or abstract fears’”
of harm. Id. (first quoting Machado Amadis v. U.S. Dep’t of State, 971 F.3d 364, 371 (D.C. Cir.
2020), then quoting S. Rep. No. 114-4, at 4 (2015)). Instead, it “must provide ‘a focused and
concrete demonstration of why disclosure of the particular type of material . . . will, in the specific
context of the agency action at issue, actually impede’ the interests protected by a FOIA
5 exemption.” Leopold v. Dep’t of Just., 94 F.4th 33, 37 (D.C. Cir. 2024) (quoting Reps. Comm. for
Freedom of the Press, 3 F.4th at 370).
IV. DISCUSSION
Thanks to the parties’ good-faith efforts to narrow the scope of this litigation—which the
court greatly appreciates—the only remaining issue is the EPA’s continued withholding, pursuant
to FOIA Exemption 5’s deliberative-process privilege, of information in three “Communities
Documents”: ED_006876A_00000023, ED_006876A_00000097, and ED_006876A_00000105.
See ECF No. 38, at 1-2; ECF No. 32-3, at 113, 148, 150. These documents are spreadsheets
containing information about different demographic entities and were part of an EPA effort to
analyze “how the results of a draft FCA Guidance . . . would apply to a cross-section of
communities.” ECF No. 32-3, at 113, 148, 150.3 CWSC argues that the EPA may not withhold
purely factual information within the Communities Documents pursuant to the deliberative-
process privilege. ECF No. 38, at 2-7. The EPA counters that such information is not segregable
because it “is inextricably intertwined with [substantial] analysis [of draft policy options],” and
because disclosure would result in foreseeable harm. ECF No. 35, at 13-16. The court agrees with
the EPA.
A. Deliberative-Process Privilege
The deliberative-process privilege is designed to “enhance the quality of agency decisions”
by shielding “‘open and frank discussion[s]’” between government officials. Hardy v. Bureau of
3 Citations to this document refer to the ECF-generated page numbers, rather than the document’s internal pagination. The Vaughn Index entries for documents -097 and -105 indicate that they are spreadsheets, see ECF No. 32-3, at 148, 150, while the redacted version of document -023 clearly shows spreadsheet column headers, id. at 113.
6 Alcohol, Tobacco, Firearms & Explosives, 243 F. Supp. 3d 155, 165 (D.D.C. 2017) (quoting Dep’t
of the Interior v. Klamanth Water Users Protective Ass’n, 532 U.S. 1, 9 (2001)); see 5 U.S.C.
§ 552(b)(5) (exempting the disclosure of “inter-agency or intra-agency memorandums or letters
that would not be available by law to a party other than an agency in litigation with the agency”).
The privilege protects “documents reflecting advisory opinions, recommendations[,] and
deliberations comprising part of a process by which governmental decisions and policies are
formulated.” Klamanth Water, 532 U.S. at 8 (quoting Nat’l Lab. Rels. Bd. v. Sears, Roebuck &
Co., 421 U.S. 132, 150 (1975)).
To qualify for the privilege, an agency document must be both (1) “pre-decisional” and
(2) “deliberative.” Hardy, 243 F. Supp. 3d at 164 (quoting Abtew v. U.S. Dep’t of Homeland Sec.,
808 F.3d 895, 898 (D.C. Cir. 2015)). “Documents are ‘predecisional’ if they are ‘generated before
the adoption of an agency policy,’ and ‘deliberative’ if they ‘reflect[] the give-and-take of the
consultive process.’” Id. (alteration in original) (quoting Jud. Watch, Inc. v. U.S. Dep’t of Def.,
847 F.3d 735, 739 (D.C. Cir. 2017)). The government bears the burden of satisfying both
components of the test. See Tax Analysts v. Internal Revenue Serv., 117 F.3d 607, 616
(D.C. Cir. 1997).
Generally speaking, factual information is not protected by the deliberative-process
privilege. See Petroleum Info. Corp. v. U.S. Dep’t of the Interior, 976 F.2d 1429, 1434
(D.C. Cir. 1992) (“Under the deliberative process privilege, factual information generally must be
disclosed, [while] materials embodying officials’ opinions are ordinarily exempt.”). But, in an
effort to prevent over-disclosure and an excessive reliance on the factual/deliberative distinction,
the D.C. Circuit has explained that “the legitimacy of withholding does not turn on whether the
material is purely factual in nature or whether it is already in the public domain, but rather on
7 whether the selection or organization of facts is part of an agency’s deliberative process.” Ancient
Coin Collectors Guild v. U.S. Dep’t of State, 641 F.3d 504, 513 (D.C. Cir. 2011). Put differently,
factual information is still protected under the deliberative-process privilege if disclosing it
“‘bear[s] on the formulation or exercise of agency policy-oriented judgment’” or “if the factual
information is ‘inextricably intertwined with the deliberative sections of documents.’” Hardy, 243
F. Supp. 3d at 165 (emphasis omitted) (first quoting Petroleum Info. Corp., 976 F.2d at 1435, then
quoting In re Sealed Case, 121 F.3d 729, 737 (D.C. Cir. 1997)).
The parties agree that the Communities Documents contain both factual information and
Agency analysis. See ECF No. 32-3, at 113, 148, 150 (explaining that each document featured
“analysis” and “real world data”). The parties primarily spar over the redaction of population data
and similar statistics from thirty-eight communities across three spreadsheets. See ECF No. 35,
at 14. The EPA asserts that these records are “composed of detailed analysis of a proposed [FCA]
methodology under consideration,” “applied real world data[,] and described the methodology . . .
step by step along with analysis, highlighted challenges, and . . . recommendations to the
workgroup.” ECF No. 35, at 13-14. In its view, the facts and analysis go hand-in-hand and cannot
be separated. ECF No. 35, at 14-15. CWSC, meanwhile, argues that purely factual information
within the documents should be segregated and disclosed, even if other parts remain protected.
ECF No. 38, at 3-7. The EPA has the better of the argument.
Agencies may not use Exemption 5 to “cloak [purely factual reports] in secrecy.” Reliant
Energy Power Generation, Inc. v. Fed. Energy Regul. Comm’n, 520 F. Supp. 2d 194, 205
(D.D.C. 2007) (quoting Bristol-Myers Co. v. Fed. Trade Comm’n, 424 F.2d 935, 939 (D.C. Cir.
1970)). But the “‘application of the deliberative process privilege is context-specific,’” meaning
that it is “‘dependent upon the individual document and the role it plays in the administrative
8 process.’” Hardy, 243 F. Supp. 3d at 168 (first quoting Edmonds Inst. v. U.S. Dep’t of the Interior,
460 F. Supp. 2d 63, 70 (D.D.C. 2006), then quoting Coastal States Gas Corp. v. Dep’t of Energy,
617 F.2d 854, 867 (D.C. Cir. 1980)). While the disputed records contain factual information about
numerous communities, their very inclusion in the documents “constitutes an exercise of judgment
by [the] agency.” Reliant Energy, 520 F. Supp. 2d at 203 (quoting Montrose Chem. Corp. v. Train,
491 F.2d 63, 71 (D.C. Cir. 1974)); see Am. Petroleum Tankers Parent, LLC v. United States, 952
F. Supp. 2d 252, 269-70 (D.D.C. 2013) (explaining that the “culling” of data “in essence creat[es]
new information as part of the deliberative process”). As the EPA’s declarant explains, the
Agency’s “staff selected the communities used in this analysis based on the availability of data
associated with the communities that would be useful to the analysis[,] not because the community
was the target of an ongoing or contemplated enforcement action.” ECF No. 35-2 ¶ 5. When it
comes to choosing data, the “work of . . . separating the wheat from the chaff is surely just as much
part of the deliberative process as is the later milling by running the grist through the mind of the
administrator.” McKinley v. Fed. Deposit Ins. Corp., 744 F. Supp. 2d 128, 140 (D.D.C. 2010)
(quoting Montrose Chem., 491 F.2d at 71). For this reason, “even if the data plugged into the
[analysis] is itself purely factual, the selection and calibration of data is part of the deliberative
process to which Exemption 5 applies.” Goodrich Corp. v. U.S. Env’t Prot. Agency, 593 F. Supp.
2d 184, 189 (D.D.C. 2009).4
4 The parties also debate whether the factual information in the Communities Documents can be segregated. See ECF No. 35, at 17-18; ECF No. 38, at 3-7. But because it is the selection of the data that is deliberative, disclosing the data itself would reveal aspects of the EPA’s decision process. See McKinley, 744 F. Supp. 2d at 140 (explaining that “disclosing the withheld factual material would reveal the [agency]’s deliberative process” because “culling . . . statistics . . . from the mass of data available to [the agency] is itself deliberative” (quoted source omitted)). As a result, the raw data is protected by the deliberative-process privilege.
9 In addition to the deliberative nature of selecting data, the disputed information also played
a key role in the EPA’s substantive, deliberative process. The Agency included the selected
communities’ data so that it could further develop and refine the implementation of FCAs.
According to the Vaughn Index entries, EPA staff were “analyzing how the results of a draft FCA
Guidance”—in other words, an in-progress proposal—“would apply to a cross-section of
communities . . . to better understand” how that policy would function in the real world. ECF
No. 32-3, at 113, 148, 150. Using the data in the Communities Documents to test policy outcomes
enabled the EPA to “refine” the version of the Guidance that “would ultimately be published for
notice and comment.” Id. The data thus played a key role in how the EPA formulated significant
policy choices, placing it squarely within the ambit of Exemption 5.
Where, as here, an agency has to “make decisions about how to look at the data, how to
select portions of the data to examine, and how to interpret the data,” the deliberative-process
privilege shields the underlying facts. Reliant Energy, 520 F. Supp. 2d at 206 (quoted source
omitted). The information about various communities within the contested records “serve[d]
primarily to reveal the ‘evaluative’ process by which different members of the decisionmaking
chain arrived at their conclusions.” Mead Data Cent., Inc. v. U.S. Dep’t of the Air Force, 575 F.2d
932, 935 (D.C. Cir. 1978) (quoting Wash. Rsch. Project, Inc. v. Dep’t of Health, Educ. & Welfare,
504 F.2d 238, 250 (D.C. Cir. 1974)). For these reasons, the deliberative-process privilege shields
the contents of the Communities Documents.
B. Foreseeable Harm
Even though the Communities Documents fit within the protections of a FOIA exemption,
the EPA must still show that disclosure would cause foreseeable harm. 5 U.S.C. § 552(a)(8). “In
the [specific] context of withholdings made under the deliberative process privilege, the
10 foreseeability requirement means that agencies must concretely explain how disclosure ‘would’—
not ‘could’—adversely impair internal deliberations.” Reps. Comm. for Freedom of the Press, 3
F.4th at 369-70 (quoting Machado Amadis, 971 F.3d at 371).
Here, the EPA’s attestations—both in the Vaughn Index and in the declarations provided
by Joseph Theis, Acting Director of the EPA’s Water Enforcement Division—satisfy this standard.
Each Vaughn entry for the Communities Documents explains that disclosure “would impair [the]
EPA’s ability to candidly assess options prior to making decisions regarding permitting and
enforcement policy.” ECF No. 32-3, at 113, 148, 150. If the EPA is unable to confidentially select
and test actual data, that would “discourage experimentation” and make it more difficult for the
Agency to complete realistic assessments of possible enforcement policy. Id. Mr. Theis further
elaborates that disclosing the source of the test data “would suggest that [the] EPA has a view of
a given community’s financial capability, compliance with the Clean Water Act, or an expectation
of how the community would respond to an enforcement action when none of those potential
inferences . . . would . . . be accurate.” ECF No. 35-2 ¶ 5. Divulging this information would
“damage [the] EPA’s relationship with the community and the states to which these communities
belong.” Id. To avoid future confusion, the EPA’s staff would likely have to resort to using
“dummy data” rather than real-world data, thus inhibiting the Agency’s ability to acquire realistic,
useful results in its testing. Id. These explanations constitute a “focused and concrete
demonstration of why disclosure . . . , in the specific context of the agency action at issue, actually
impede[s] . . . agency deliberations going forward.” Reps. Comm. for Freedom of the Press, 3
F.4th at 370. Accordingly, the EPA has met its burden of demonstrating foreseeable harm.
11 V. CONCLUSION
For the foregoing reasons, the court will grant the EPA’s motion for summary judgment,
ECF No. 32, and deny CWSC’s cross-motion for summary judgment, ECF No. 33. A
contemporaneous order will issue.
