15

In this case, Plaintiff Center for Biological Diversity (the "Center") is suing

16

Defendants United States Fish & Wildlife Service ("FWS" or the "Service") and Debra

17

Haaland in her official capacity as Secretary of the United States Department of the

18

Interior.1 Plaintiff alleges Defendants have unreasonably delayed completing interagency

19

consultations on the pesticides chlorpyrifos, diazinon, carbaryl, methomyl,2 atrazine, and

20

simazine in violation of the Endangered Species Act ("ESA") and the Administrative

21

Procedure Act ("APA"). Before the Court are the parties' cross-motions for summary

22

judgment (Docs. 34, 38). The issues are fully briefed (Docs. 41, 42), and oral argument

23

occurred on December 12, 2024, see Doc. 46.

24

Plaintiff's Motion for Summary Judgment asked the Court to impose a January 15,

25

2025 deadline for FWS to complete consultation on all six pesticides. Defendants' Cross-

26

27
28

Debra Haaland is no longer the Secretary of the Interior. Pursuant to Federal Rule of Civil
Procedure 25(d), Doug Burgum is automatically substituted in her place.
2
FWS completed interagency consultation on methomyl on December 30, 2024, according
to its estimated timeline. See Doc. 47. Plaintiff's request for a court-imposed deadline for
the methomyl consultation is now moot. The Court includes references to the methomyl
timeline for context only.

1

Motion for Summary Judgment offers a series of dates by which they estimate FWS could

2

realistically complete the consultations: March 31, 2025, for carbaryl; March 31, 2026, for

3

atrazine and simazine; and September 30, 2028, for chlorpyrifos and diazinon. Plaintiff's

4

Response and Reply asks the Court to order FWS to adhere to its estimated timelines for

5

carbaryl, atrazine, and simazine. But Plaintiff disagrees with Defendants' September 30,

6

2028 completion date for the chlorpyrifos and diazinon consultations. Plaintiff asks the

7

Court to instead order FWS to complete the chlorpyrifos and diazinon consultations by

8

June 30, 2027. For the reasons set forth below, the Court will grant in part Plaintiff's Motion

9

for Summary Judgment, deny Defendants' Cross-Motion for Summary Judgment, and

10

order FWS to complete consultation on each pesticide according to Defendants' proposed

11

timelines.

12

I.

Background

13

A. Statutory and Regulatory Framework

14

This case arises out of FWS's obligations under Section 7 of the ESA. The ESA is

15

"the most comprehensive legislation for the preservation of endangered species ever

16

enacted by any nation." Tenn. Valley Auth. v. Hill, 437 U.S. 153, 180 (1978). It was enacted

17

to "halt and reverse the trend towards species extinction, whatever the cost." Id. at 184.

18

Pertinent here is Section 7(a)(2), which requires federal agencies to,

19
20
21
22
23
24
25
26
27
28

in consultation with and with the assistance of the Secretary, insure that any
action authorized, funded, or carried out by such agency . . . is not likely to
jeopardize the continued existence of any endangered species or threatened
species or result in the destruction or adverse modification of [critical] habitat
of such species . . . .
16 U.S.C. § 1536(a)(2). FWS and National Marine and Fisheries Service ("NMFS") share
responsibility for administering the ESA and serve as the consulting agencies for
endangered or threatened species under their respective jurisdictions. See 50 C.F.R.
§ 401.02.
Relevant here, if a federal agency determines a prospective agency action "may
affect a listed species or habitat" within FWS's jurisdiction, the agency must initiate formal
consultation with FWS. See 50 C.F.R. § 402.14(a). The agency, here the Environmental
-2-

1

Protection Agency ("EPA"), makes this determination by conducting a biological

2

evaluation ("BE").3 To complete formal consultation, FWS responds to the BE with a

3

biological opinion ("BO") establishing the likelihood of jeopardy to protected species and

4

habitats and suggesting reasonable alternatives or cautionary measures to reduce adverse

5

impact. 16 U.S.C. § 1536(b)(3)(A).

6

When an agency initiates formal consultation, it must include a description of the

7

proposed action, providing sufficient detail to allow FWS to "assess the effects of the action

8

on listed species and critical habitat." 50 C.F.R. § 402.14(c)(1)(i). The "effects of the

9

action" are those consequences that are "reasonably certain to occur." 50 C.F.R. § 402.02.

10

The agency must provide FWS with "the best scientific and commercial data available or

11

which can be obtained during the consultation for an adequate review of the effects that an

12

action may have upon listed species or critical habitat." 50 C.F.R. § 402.14(d); see also 16

13

U.S.C. § 1536(a)(2) ("In fulfilling the requirements of this paragraph each agency shall use

14

the best scientific and commercial data available.").

15

Section 7 requires consultations to conclude within 90 days of initiation or "within

16

such other period of time as is mutually agreeable" between the agency and FWS.

17

16 U.S.C. § 1536(b)(1)(A). If the prospective action involves a permit or license applicant,

18

the extension cannot exceed 150 days from the consultation's initiation unless FWS and

19

the agency obtain the applicant's consent for the extension. 16 U.S.C. § 1536(b)(1)(B).

20

FWS can request an extension when it "determines that additional data would provide a

21

better information base from which to formulate a biological opinion." Id.

22

If the parties agree to extend formal consultation,

23

the Federal agency shall obtain, to the extent practicable, that data which can
be developed within the scope of the extension. . . . The Service's request for
additional data is not to be construed as the Service's opinion that the Federal
agency has failed to satisfy the information standard of section 7(a)(2) of the
Act. If no extension of formal consultation is agreed to, the Director will
issue a biological opinion using the best scientific and commercial data
available.

pesticides: chlorpyrifos, diazinon, carbaryl, methomyl, atrazine, and simazine. Doc. 34
at 2.5 Chlorpyrifos, diazinon, carbaryl, and methomyl are insecticides used as active
ingredients in pesticide products. Doc. 35 ¶¶ 4, 34; Doc. 39 ¶¶ 4, 34. Atrazine and simazine
are herbicides used as active ingredients in pesticide products. Doc. 35 ¶ 53; Doc. 39 ¶ 53.
Chlorpyrifos, diazinon, carbaryl, and methomyl can be neurotoxic to animals. See Doc. 35
¶¶ 6, 35; Doc. 39 ¶¶ 6, 35. Atrazine and simazine can "vary from slightly to highly toxic to
animals," Doc. 35 ¶ 54, though additional factors (e.g., level of exposure) impact whether
an animal may experience toxic effects, Doc. 39 ¶ 54. Consequences of animal exposure
to these pesticides can include impairment of behaviors, reproduction, and growth;
inhibition of normal brain and muscle function; loss of food sources and symbiotic
partners; and eventually, mortality. Doc. 35 ¶¶ 7, 35, 54; Doc. 39 ¶¶ 7, 35, 54. Though their
authorized uses vary, these pesticides are often applied on agricultural crops, golf courses
and other turf, and feed and food crops, among other surfaces. Doc. 35 ¶¶ 42–43, 50, 59,
62; Doc. 35 ¶¶ 42–43, 50, 59, 62. In its BEs initiating consultation, the EPA found that,
based on the then-current pesticide registrations, thousands of ESA-protected species and
habitats may be susceptible to harm from these pesticides. See Doc. 35 ¶¶ 9, 13, 36, 39, 55,
57; Doc. 39 ¶¶ 9, 13, 36, 39, 55, 57; see also AR 0011815–16, 0012140–41, 0012322,

The parties agree on the material facts. Compare Doc. 35, with Doc. 39. Prior to filing
cross motions for summary judgment, the parties cooperated in filing an administrative
record. See Doc. 40. Plaintiff's Motion for Summary Judgment preemptively argues that
because there has been no final agency action, the Court's review of Plaintiff's unreasonable
delay claims is not limited to the administrative record. Doc. 34 at 24–25. Defendants do
not object to any of Plaintiff's evidence, see generally Docs. 38, 39. At oral argument, the
parties agreed the facts are undisputed and the Court has everything it needs to issue a
ruling. Dec. 12, 2024 Oral Arg. Tr. 4:21–6:1. As such, the Court will base its review on
both the administrative record and the declarations attached to the motions for summary
judgment.

12, 0021720–22, 0022344–47, 0022376–78. In July 2014, the EPA, FWS, and NMFS

5

agreed to complete pilot nation-wide consultations7 on chlorpyrifos and diazinon

6

tentatively by December 2017 and carbaryl and methomyl tentatively by December 2018.

7

Doc. 35 ¶ 78; Doc. 39 ¶ 78; see also AR 0022426–27. In February 2016, the agencies

8

reaffirmed these deadlines and agreed to complete consultations on atrazine and simazine

9

by December 2022. Doc. 35 ¶ 80; Doc. 39 ¶ 80; see also AR 0022474, 0022488.

10

FWS transmitted its final BO and completed consultation on methomyl on

11

December 30, 2024. See Doc. 47. FWS has yet to complete formal consultation on

12

chlorpyrifos, diazinon, carbaryl, atrazine, or simazine. To analyze the progression of each

13

consultation, the Court will group the pesticides into three categories: chlorpyrifos and

14

diazinon, carbaryl and methomyl, and atrazine and simazine.

15

Chlorpyrifos and Diazinon

16

In January 2017, the EPA initiated formal consultation with FWS by transmitting

17

BEs on chlorpyrifos and diazinon. Doc. 35 ¶¶ 9, 13; Doc. 39 ¶¶ 9, 13; see also

18

AR 0011815–16, 0012140–41. In the BEs, the EPA found the then-registered uses for

19

chlorpyrifos were "likely to adversely affect" 97% of ESA-protected species and 98% of

20

ESA critical habitats. Doc. 35 ¶ 9; Doc. 39 ¶ 9; see also AR 0011815–16. The EPA also

21

found the then-registered uses of diazinon were "likely to adversely affect" 78% of ESA-

22

protected species and 48% of critical habitats. Doc. 35 ¶ 13; Doc. 39 ¶ 13; see also

23

AR 0012140–41. These effects determinations were based on the pesticides' maximum

24

use authorized by the EPA and do not necessarily reflect how the pesticides are used in

25
26
27
28

Rodenticide Act ("FIFRA") during which the EPA revaluates a pesticide's authorization to
be sold or distributed in the United States. See 7 U.S.C. § 136a(a), (g). The initiation of
registration review signals a prospective agency action triggering the EPA's duties under
the ESA. See Doc. 34 at 20.
7
Prior to this agreement, formal consultation under the ESA had been limited to evaluating
impact of prospective agency action on a species-by-species basis. See Doc. 39 ¶ 78. The
consultations here involve all species and geographical areas under FWS's jurisdiction.
-5-

practice. See Doc. 39 ¶¶ 11, 15; see also AR 0014883.

2

In an October 2017 draft BO on chlorpyrifos, FWS preliminarily concluded the

3

uses described in the chlorpyrifos BE would jeopardize 88% of ESA-protected species and

4

adversely modify 23% of critical habitats. Doc. 35 ¶ 11; Doc. 39 ¶ 11; AR 0022546. In an

5

October 2017 draft BO on diazinon, FWS preliminarily concluded the uses described in

6

the diazinon BE would jeopardize 12% of ESA-protected species and adversely modify

7

3% of critical habitats. Doc. 35 ¶ 15; Doc. 39 ¶ 15; AR 0022546. During internal review,

8

FWS became concerned about the legal consequences of issuing BOs analyzing the

9

pesticides' maximum authorized use and not their actual use. Doc. 39 ¶¶ 11, 15. Because

10

the ESA implementing regulations require FWS to analyze those effects that are

11

"reasonably certain to occur," FWS determined it needed additional usage data from the

12

EPA. Id. (quoting 50 C.F.R. § 402.02); see also Doc. 38 at 12. In December 2017, pursuant

13

to a court-ordered deadline, NMFS issued a final BO on chlorpyrifos and diazinon. Doc. 35

14

¶ 109; Doc. 39 ¶ 109. The EPA provided FWS with updated usage information on

15

chlorpyrifos and diazinon in 2018. Doc. 38-1 ¶ 14. FWS has not issued final BOs on

16

chlorpyrifos or diazinon to date. Doc. 35 ¶ 127; Doc. 39 ¶ 127.

17

There have been several updates to how chlorpyrifos and diazinon are used in

18

practice since the EPA initiated consultation in 2017. See generally Doc. 39 ¶¶ 10–33. In

19

August 2021, the EPA issued a final rule revoking all use of chlorpyrifos on food.8 Doc. 35

20

¶ 114; Doc. 39 ¶ 114. In June 2022, NMFS updated its BO on chlorpyrifos and diazinon,

21

Doc. 35 ¶ 119; Doc. 39 ¶ 119; see also AR 0012960–4344, resulting in changed

22

registrations for the pesticides, Doc. 38-1 ¶ 20. In October 2022, diazinon registrants

23

voluntarily cancelled registrations for nine products. Doc. 35 ¶ 122; Doc. 39 ¶ 122. In 2023,

24
8

25
26
27
28

In response to this rule, FWS "suspend[ed] work on development of the chlorpyrifos
biological opinion" pending the EPA's final decision on approved uses. AR 0012959. The
memorandum announcing the suspension stated FWS expected that "with the announced
changes, EPA will complete a new risk assessment with the revised uses and subsequently
reinitiate consultation at which point [FWS] would resume work on the biological opinion
using EPA’s revised risk assessment." Id. The rule was subsequently vacated by court order
in November 2023. Doc. 35 ¶ 123; Doc. 39 ¶ 123. In response, the EPA confirmed in
December 2023 that all chlorpyrifos tolerances would automatically resume effect. Doc. 35
¶ 124; Doc. 39 ¶ 124.

diazinon registrants and the EPA reached an agreement for additional mitigation measures.

Doc. 8-1 ¶ 29; see also AR 0014345–436, 0014458, 0014472–76.

3

In March 2020, the EPA revised the methodology used for its BEs to analyze the

4

effects of the action reasonably certain to occur. See Doc. 39 ¶ 3; Doc. 38-1 ¶ 13. FWS

5

plans to use information produced by this new methodology in its chlorpyrifos and diazinon

6

BOs. Doc. 39 ¶ 3. Pursuant to a court order in another case with Plaintiff, the EPA expects

7

to update its strategies to address vulnerable species that may be affected by insecticides

8

("insecticide strategies") by March 31, 2025. Doc. 38-1 ¶¶ 34–35; see also AR 0021511–

9

22. The EPA is also currently completing a new risk assessment for diazinon, the results

10

of which are expected in summer 2026. Doc. 38-1 ¶ 26. Accordingly, the EPA expects to

11

provide FWS with supplemental information to its chlorpyrifos and diazinon BEs by March

12

31, 2027. See, e.g., Doc. 39 ¶ 3. Based on the EPA's timeline, FWS expects to complete

13

the chlorpyrifos and diazinon consultations by September 30, 2028. Doc. 38-1 ¶¶ 35, 57.

14

Carbaryl and Methomyl

15

In March 2021, the EPA initiated formal consultation with FWS with BEs on

16

carbaryl and methomyl. Doc. 35 ¶¶ 36, 39; Doc. 39 ¶¶ 36, 39; see also AR 0012322,

17

0012374. The carbaryl BE reported that carbaryl was "likely to adversely affect" 91% of

18

ESA-protected species and 93% of critical habitats. Doc. 35 ¶ 36; Doc. 39 ¶ 36; see also

19

AR 0012322. The methomyl BE determined that methomyl was "likely to adversely affect"

20

61% of ESA-protected species and 36% of critical habitats. Doc. 35 ¶ 39; Doc. 39 ¶ 39;

21

see also AR 0012374.9 In ESA Section 7(b) letters to extend formal consultation, FWS

22

requested the EPA provide it with additional usage data among other information.

23

Doc. 38-1 ¶¶ 47–48; AR 0012723–24, 0024353–54. The EPA agreed to the extension, and

24

the agencies obtained the required consent from the registrants. Id.

25

NMFS issued a BO for carbaryl and methomyl in January 2024, resulting in changed

26

registrations for both pesticides that are likely to have mitigated their effects.10 Doc. 35

Updated information resulted in "likely to adversely affect" determinations for 1,020
species and 281 critical habitats, slightly less than the number of "likely to adversely affect"
determinations in the original 2021 BE. Doc. 39 ¶ 39.

¶ 147; Doc. 39 ¶ 147; see also AR 0023558–73, 0024089–96. In July 2024, FWS released

2

its draft methomyl BO. Doc. 39 ¶ 84; see also AR 0040181–402. On December 30, 2024,

3

FWS transmitted its final methomyl BO to the EPA. Doc. 47. On December 26, 2024, FWS

4

issued its draft carbaryl BO. Id. FWS now expects to complete consultation on carbaryl by

5

March 31, 2025.11 Doc. 38-1 ¶¶ 53, 57.

6

Atrazine and Simazine

7

In November 2021, the EPA initiated consultation with FWS with BEs on atrazine

8

and simazine, finding atrazine was "likely to adversely affect" 56% of ESA-protected

9

species and 41% of critical habitats,12 and simazine was "likely to adversely affect" 55%

10

of ESA-protected species and 40% of critical habitats. Doc. 35 ¶¶ 55, 57; Doc. 39 ¶¶ 55,

11

57; see also AR 0012577, 0012684. In ESA Section 7(b) letters to extend formal

12

consultation, FWS requested the EPA provide it with additional usage data among other

13

information. Doc. 38-1 ¶¶ 47, 54; see also AR 0012756–68. The EPA agreed to the

14

extension, and the agencies obtained the required consent of the pesticide registrants. Id.

15

The EPA is currently providing the updated information on a rolling basis, Doc. 38-1 ¶ 49,

16

and FWS expects to complete consultation on atrazine and simazine by March 31, 2026.13

17

Doc. 38-1 ¶¶ 56, 57.

18

Relevant Context

19

While the formal consultations on these six pesticides have been pending, FWS has

20

concluded consultation on three other pesticides. See Doc. 35 ¶ 84; Doc. 39 ¶ 84; see also

21

AR 0014883–5213, 0015709–877. Along with chlorpyrifos and diazinon, the EPA also

22

initiated consultation on malathion, another similar pesticide, in January 2017. Doc. 35

23

¶¶ 93–94; Doc. 39 ¶¶ 93–94. After its initial BE, the EPA updated the usage information

24

on malathion in 2018 and started to provide additional information pursuant to its revised

25
26
27
28

mitigation. See Doc. 39 ¶ 40; Doc. 38-1 ¶¶ 49–51.
11
The EPA and the respective pesticide registrants have agreed to these deadlines. See
Doc. 35 ¶¶ 137–39; Doc. 39 ¶¶ 137–39.
12
Since the EPA transmitted its BE, there have been label changes for atrazine, likely
resulting in some mitigation. Doc. 39 ¶ 55.
13
The EPA and the respective pesticide registrants have agreed to this deadline. See
Doc. 35 ¶¶ 165–66; Doc. 39 ¶¶ 165–66.

2

0021347–405. In 2018, malathion became the subject of litigation between the parties in

3

another case, resulting in FWS stipulating to a deadline and issuing its malathion BO in

4

February 2022. See Doc. 35 ¶ 116; Doc. 39 ¶ 116; see also Ctr. for Env't Health v. Regan,

5

No. 4:18-cv-03197-SBA (N.D. Cal. Jan. 4, 2022). The malathion BO contained 19,000

6

pages of analysis. Doc. 38-1 ¶ 14. FWS also issued BOs for herbicides Enlist and Enlist

II.

Legal Standards

10

A. Review Under the APA

11

The APA provides that all federal agencies must conclude matters presented to them

12

"within a reasonable time." 5 U.S.C. § 555(b). Federal courts have jurisdiction to review

13

mandatory agency action and "compel agency action unlawfully withheld or unreasonably

14

delayed." 5 U.S.C. § 706(1). Under the APA, a court may compel delayed agency action

15

when the agency "(1) has 'a clear, certain, and mandatory duty' and (2) has unreasonably

16

delayed in performing such duty." Vaz v. Neal, 33 F.4th 1131, 1136 (9th Cir. 2022)

17

(citations omitted) (quoting Plaskett v. Wormuth, 18 F.4th 1072, 1082 (9th Cir. 2021)).14

18

The issuance of equitable relief under section 706 of the APA "is an extraordinary remedy

19

and [the Court] require[s] similarly extraordinary circumstances to be present before [it]

20

will interfere with an ongoing agency process." Biodiversity Legal Found. v. Norton, 285

21

F. Supp. 2d 1, 12 (D.C. Cir. 2003) (alterations in original) (quoting Cmty. Nutrition Inst.

v. Young, 773 F.2d 1356, 1361 (D.C. Cir. 1985)).

23

B. Summary Judgment

24

Summary judgment is required if "the pleadings, depositions, answers to

25

interrogatories, and admissions on file, together with the affidavits, if any, show that there

26

is no genuine issue as to any material fact and that the moving party is entitled to judgment

27

Defendants did not contest that FWS has a clear and certain duty to complete the
pesticide consultations under 16 U.S.C. § 1536. Accordingly, the Court will only analyze
unreasonable delay.

as a matter of law." Fed. R. Civ. P. 56(c). Summary judgment is a particularly appropriate

2

tool for resolving claims challenging agency action. See Occidental Eng'g Co. v. INS, 753

F.2d 766, 770 (9th Cir. 1985).

III.

Analysis

5

Plaintiff brings six counts alleging FWS has violated Section 555(b) of the APA by

6

unreasonably delaying completing consultation on six pesticides, justifying judicial

7

intervention under APA Section 706(1). "[T]here is no per se rule as to what amount of

8

time constitutes undue delay." Oceana v. Bureau of Ocean Energy Mgmt., 37 F. Supp. 3d

9

147, 184–85 (D.C. Cir. 2014). Instead, the Court engages in a fact-specific inquiry to

10

determine if agency action has been unreasonably delayed. See Al Otro Lado v. Exec. Off.

11

for Immigr. Rev., 120 F.4th 606, 622 (9th Cir. 2024). To aid in this determination, the Ninth

12

Circuit has adopted the "TRAC" balancing test. Telecomms. Rsch. & Action Ctr. v. FCC,

13

750 F.2d 70, 79–80 (D.C. Cir. 1984) ("TRAC"); see Vaz, 33 F.4th at 1137 (9th Cir. 2022).

14

The test looks at six factors ("the TRAC Factors"):
(1) the time agencies take to make decisions must be governed by a "rule of
reason";
(2) where Congress has provided a timetable or other indication of the speed
with which it expects the agency to proceed in the enabling statute, that
statutory scheme may supply content for this rule of reason;
(3) delays that might be reasonable in the sphere of economic regulation are
less tolerable when human health and welfare are at stake;
(4) the court should consider the effect of expediting delayed action on
agency activities of a higher or competing priority;
(5) the court should also take into account the nature and extent of the
interests prejudiced by delay; and
(6) the court need not find any impropriety lurking behind agency lassitude
in order to hold that agency action is "unreasonably delayed."

TRAC, 750 F.2d at 80 (citations and quotations omitted).15

The relevant factors here inform three core considerations: first, whether FWS's
delay in completing consultation on the pesticides violates the rule of reason; second, the
extent of the potential harm caused and interests prejudiced by the delay; and third, the

27
15

28

Because the D.C. Circuit has "more frequently dealt with unreasonably delayed
rulemakings," the Court will look to D. C. Circuit authority in explaining and applying the
TRAC factors. See Cmty. Voice v. EPA, 878 F.3d 779, 788 (9th Cir. 2017).

impact of compelling agency action on other agency priorities. See Milligan v. Pompeo,

2

502 F. Supp. 3d 302, 317 (D.D.C. 2020) (first and second factors often considered

3

together); In re Ctr. for Biological Diversity, 53 F.4th 665, 671 (D. C. Cir. 2022) (third and

4

fifth factors often considered together). The Court will address these three inquiries in turn.

5

A. The Rule of Reason

6

The first TRAC factor, which provides that the time it takes for an agency to act

7

must be governed by a "rule of reason," is the "'most important' factor." Vaz, 33 F.4th

8

at 1138 (quoting Cmty. Voice, 878 F.3d at 786). There is no per se rule on what is

9

reasonable, but courts have repeatedly emphasized "a reasonable time for agency action is

10

typically counted in weeks or months, not years." Id. (internal quotations omitted) (quoting

11

Nat. Res. Def. Council v. EPA, 956 F.3d 1134, 1139 (9th Cir. 2020)). The second TRAC

12

factor, whether Congress has provided a timetable for action, can also inform a

13

reasonability inquiry. TRAC, 750 F.2d at 80. Accordingly, these factors are typically

14

considered together. Milligan, 502 F. Supp. at 317.

15

1. Years-Long Delay

16

Plaintiff argues FWS's years-long delay in completing consultation on each of the

17

pesticides is unreasonable given FWS's informal involvement years before the EPA

18

initiated formal consultation, its failure to release draft opinions created over seven years

19

ago, and that its sister agency, NMFS, has already completed consultation on four of the

20

six pesticides at issue. Doc. 34 at 28–29. The EPA initiated registration review under

21

FIFRA for diazinon and chlorpyrifos in 2008 and 2009 respectively, carbaryl and

22

methomyl in 2010, and atrazine and simazine in 2013. Doc. 35 ¶¶ 87, 89, 128, 130, 150,

23

152. Registering a pesticide is an agency action subject to the ESA consultation process.16

24

This means FWS has been or should have been aware of the potential need for formal

25

consultation on each of these pesticides for over 10 years but has yet to act. See Doc. 35

26

¶ 86. This is despite the EPA and FWS's 2014 and 2016 agreements to complete the

27
16

28

See Pesticide Registration and Endangered Species Consultation, U.S. Fish & Wildlife
Service, https://www.fws.gov/library/collections/pesticide-registration-and-endangeredspecies-act-consultations.
- 11 -

1

consultations for chlorpyrifos and diazinon, carbaryl and methomyl, and atrazine and

2

simazine by the end of 2017, 2018, and 2022 respectively.17 Doc. 35 ¶¶ 78, 80.

3

Even disregarding the informal notice, formal consultation has been pending before

4

FWS on these pesticides for at least three and a half years.18 See Doc. 35 ¶¶ 9, 13, 55, 57;

5

Doc. 39 ¶¶ 9, 13, 55, 57. FWS gives various reasons these consultations have not been

6

completed, including changes to pesticide labels, a need for updated or additional

7

information, and a lack of resources in the face of other priorities. See generally Doc. 38

8

at 20–28. It seems certain circumstances beyond Defendants' control have contributed to

9

FWS's failure to complete these consultations. But these circumstances do not excuse the

10

lengthy delays presented here.

11

Defendants cite several cases where courts have declined to find similarly lengthy

12

timelines unreasonable, but none justify endorsing the years-long delay here. See In re

13

UMW Int'l Union, 190 F.3d 545, 546, 556 (D. C. Cir. 1999) (finding that ordering an

14

agency to conclude a rulemaking could "do more harm than good" where it would displace

15

other rulemakings the parties agreed were of greater significance to health and safety);

16

Mashpee Wampanoag Tribal Council, Inc. v. Norton, 336 F.3d 1094, 1099, 1101–02

17

(D. C. Cir. 2003) (reversing an order directing agency action because the district court did

18

not consider "'competing priorities' for limited resources," and there was no reason to upset

19

the BIA's "first-come procedure"); Grand Canyon Air Tour Coal. v. FAA, 154 F.3d 455

20

(D. C. Cir. 1998) (declining to find unreasonable delay and order the "immediate

21

imposition" of a drastic remedy that may have unintended consequences where Congress

22

contemplated the development rather than implementation of a plan within the statutory

23

timeframe); Biodiversity Legal Found. v. Norton, 285 F. Supp. 2d 1 (D.D.C. 2003)

(declining to find a four-year delay unreasonable where there was no express statutory

Completion of formal consultation requires the EPA to complete initiating BEs. The
EPA did not release its BE for carbaryl and methomyl until years after the agencies had
agreed to complete consultation, but the BEs for chlorpyrifos, diazinon, atrazine and
simazine were released a year or more prior to the dates by which the agencies had agreed
to complete consultation. See Doc. 35 ¶¶ 11, 13, 36, 39, 55, 57.
18
EPA initiated formal consultation on atrazine and simazine about three and a half years
ago, carbaryl and methomyl about four years ago, and chlorpyrifos and diazinon about
eight years ago.

deadline, "reflect[ing] a general congressional priority" for other duties towards which the

2

agency was directing resources); Oceana v. Bureau of Ocean Energy Mgmt., 37 F. Supp.

3

3d 147, 178, 186 (D.C. Cir. 2014) (declining to find NMFS's delay in updating BOs on

4

lease sales after the Deep Water Horizon oil spill unreasonable because they were a

5

"narrow, circumscribed event in the [statutory scheme] that [would] have minimal impact

6

on endangered species," and it was "unclear how any delay in NMFS's BO would harm the

7

human environment").

8

This case is distinguishable from the cases above. These BOs involve nationwide

9

consultations on pesticides with the potential to cause extensive harm. The Section 7

10

consultations are the "heart of the ESA," W. Watersheds Project v. Kraayenbrink, 632 F.3d

11

472, 495 (9th Cir. 2011), and FWS does not allege other consultations of greater

12

significance are pending. There seem to be few competing priorities that would justify

13

letting nationwide consultations that, based on the only data available could impact most

14

protected species and habitats, languish for around eight years. Further, as discussed more

15

extensively below, the Court is not reordering agency priorities or requiring FWS to act

16

any sooner than Defendants believe is necessary to produce sound BOs. The Court is

17

simply directing FWS to abide by its own proffered timelines.

18

2. Best Available Evidence

19

Defendants justify FWS's delay by detailing the ways the registrations and usage

20

information have changed for chlorpyrifos and diazinon since the EPA initiated

21

consultation, necessitating updated information. See Doc. 38 at 20–21.19 For carbaryl,

22

19

23
24
25
26
27
28

At oral argument, Defendants argued "the clock has reset" on the chlorpyrifos and
diazinon consultation timelines. See Dec. 12, 2024, Oral Arg. Tr. 36:15–19. According to
Defendants, because chlorpyrifos and diazinon have new proposed actions, FWS’s
deadlines "are not triggered until [it] knows what [it] is consulting on." Id. Defendants cite
no case law or statute to support their argument that registration changes over the eight
years they have failed to complete consultation abrogates their statutory duty to perform
those consultations. Defendants further fail to pinpoint a specific event that triggered a
reset. The only evidence the Court has found is a 2021 FWS internal memorandum
suspending development of the chlorpyrifos BO. See AR 0012959. The memorandum was
issued in response to an EPA rule revoking all tolerance for use of chlorpyrifos on food.
See id. Per the memorandum, FWS anticipated the EPA would "complete a new risk
assessment with the revised [chlorpyrifos] uses and subsequently reinitiate consultation."
Id. The EPA’s rule revoking all tolerance for use of chlorpyrifos on food was overturned
by court order in November 2023. See Doc. 35 ¶¶ 123–24; Doc. 39 ¶¶ 123–24. It is unclear
- 13 -

1

atrazine, and simazine, FWS emphasizes its need for "essential" additional information.

2

Doc. 38 at 21–22. Defendants are correct that the ESA's implementing regulations provide

3

that "[t]he Federal agency requesting formal consultation shall provide the Service with the

4

best scientific and commercial data available or which can be obtained during

5

consultation." 50 C.F.R. § 402.14(d). Further, "[w]hen the Service determines that

6

additional data would provide a better information base from which to formulate a

7

biological opinion, the Director may request an extension of formal consultation and

8

request that the federal agency obtain additional data to determine how or to what extent

9

the action may affect the listed species or critical habitat." 50 C.F.R. § 402.14(f).

10

The "best available evidence" requirement does not, however, require or authorize

11

unlimited delay in pursuit of the most up-to-date data. "The purpose of the best available

12

evidence standard is to prevent an agency from basing its action on speculation and

13

surmise." San-Luis & Delta-Mendota Water Authority v. Locke, 776 F.3d 971, 995 (9th

14

Cir. 2015). This does not mean an agency must "conduct new tests or make decisions on

15

data that does not yet exist." Id. Instead, an agency complies with the standard "so long as

16

it does not ignore available studies." Id.; see also Desert Survivors v. U.S. Dep't of Interior,

17

321 F. Supp. 3d 1011, 1041–41 (N.D. Cal. 2018) ("[W]here superior information is not

18

readily available, the 'best available science' requirement of the ESA does not 'insist on

19

perfection' and does not require the 'best scientific data possible.'") (quoting Building Indus.

20

Ass'n v. Norton, 247 F.3d 1241, 1246 (D.C. Cir. 2001)). Scientific findings in conservation

21

are "often necessarily made from incomplete or imperfect information." Brower v. Evans,

22
23
24
25
26
27
28

if FWS ever resumed work on the BO.
Regardless of FWS’s internal decision to suspend consultation, the need for
additional information does not dispense with the duty to complete consultation. See 50
C.F.R. § 402.14(f) (If the agencies agree to an extension for additional data "the Federal
agency shall obtain, to the extent practicable, the data which can be developed within the
scope of the extension . . . . The Service’s request for additional data is not to be construed
as the Service’s opinion that the Federal agency has failed to satisfy the information
standard of section 7(a)(2) of the Act. If no extension of formal consultation is agreed to,
the Director will issue a biological opinion using the best scientific and commercial data
available."). Here, FWS has not obtained an extension for the chlorpyrifos and diazinon
consultations. Even if it had, the ability to delay consultation to await additional data is not
unlimited, and formal consultation must eventually be completed with the "best scientific
or commercial data available."
- 14 -

1

257 F.3d 1058, 1070 (9th Cir. 2001); see also id. at 1071 ("Given the best available

2

evidence standard . . . the Secretary cannot use insufficient evidence as an excuse for failing

3

to comply with the statutory requirement.").

4

Courts have previously found "arbitrary and capricious" reliance on outdated data

5

to form a BO. Dow AgroSciences LLC v. Nat'l Marine Fisheries Serv., 707 F.3d 462, 472

6

(4th Cir. 2013) (finding an NMFS BO to be "arbitrary and capricious" where NMFS

7

"recognized that it was relying on outdated data and that it had been presented with more

8

recent data, but it chose to continue relying on the outdated data without explaining why").

9

Courts have also recognized "that an agency need not revise its action every time new data

10

or a new model is announced because doing so 'would lead to significant costs and

11

potentially endless delays in the approval process.'" Id. at 473 (quoting Sierra Club v. EPA,

12

356 F.3d 296, 308 (D.C. Cir. 2004)).

13

Defendants' claim that FWS's timeline for issuing each BO is "entirely dependent

14

on when the EPA provides the necessary supplemental information" is exaggerated. See

15

Doc. 42 at 20. NMFS receives the same information and BEs as FWS, see Dec. 12, 2024,

16

Oral Arg. Tr. 51:25–52:19, and NMFS has completed consultation on chlorpyrifos,

17

carbaryl, and methomyl, and updated its BOs on chlorpyrifos and diazinon. Doc. 35 ¶¶ 109,

18

119, 147; Doc. 39 ¶¶ 109, 119, 147. If NMFS can use the existing information to complete

19

BOs without violating the best available evidence requirement, there seems to be no reason

20

FWS cannot do the same. Section 7 provides FWS can request additional data that "to the

21

extent practicable . . . can be developed within the scope of the extension." 50 C.F.R.

22

§ 402.14(f) (emphasis added). Accordingly, the argument that FWS must wait for data that

23

has not yet been developed (or that might result from pending mitigation efforts and

24

updated EPA methodology) is inconsistent with the statutory requirements. It is because

25

Defendants have delayed action for so long that the EPA's original BEs may now be

26

obsolete. That mitigation has occurred even without consultation is no excuse for FWS's

27

continued failure to act.

28

///

- 15 -

1

3. Congressional Timetable

2

Plaintiff points to the ESA's provision setting a default timeline and intention for

3

consultation to be completed prior to agency action as further evidence that FWS's delay

4

is unreasonable. See Doc. 34 at 29–33. The ESA contemplates a 90-day timeline for FWS

5

to conclude formal consultation. 16 U.S.C. § 1536(b)(1)(A). Some courts have interpreted

6

Section 7's extension provision to mean the agencies "have a great deal of discretion in

7

mutually setting their own timelines." Oceana, 37 F. Supp. 3d at 186. But "[t]he fact that

8

the ESA allows for extension of the consultation timeline does not mean that any and all

9

delay is reasonable." Center for Environmental Health v. Wheeler, 429 F. Supp. 3d 702,

10

716 (N.D. Cal. 2019). Otherwise, "delay in completing consultation [could] never be

11

unreasonable." Id. "To so hold would be to sanction the perpetual delay of governmental

12

obligations that are clearly mandated by law." Id. Here, FWS has followed the statutory

13

requirements and extended its consultations on carbaryl, atrazine, and simazine. Doc. 35

14

¶¶ 137–39, 165–66; Doc. 39 ¶¶ 137–39; 165–66. But these pesticides have already been

15

registered, and the applicants have no incentive to expedite consultation. See Doc. 34 at 23

16

n. 6. This is not enough to make FWS's delay reasonable where originally three- to five-

17

month timelines have now dragged on for years.

18

Even though the ESA does not mandate consultation always be completed in 90

19

days, the timetable provides an "indication of the speed with which it expects the agency

20

to proceed." TRAC, 750 F.2d at 80. For EPA Section 7 consultations, that speed is months,

21

not years. The purpose of these consultations further informs a reasonable timeline.

22

Congress intended Section 7 consultations to evaluate agency action prospectively. 16

23

U.S.C. § 1536(a)(3) ("[A] Federal agency shall consult with the Secretary on any

24

prospective agency action . . . ."); In re Ctr. for Biological Diversity & Ctr. for Food Safety,

25

53 F.4th 665, 671 (D.C. Cir. 2022) ("The ESA required EPA to issue an effects

26

determination and engage in any required consulting before registering [the pesticide].").

27

Given this, it makes little sense that Congress would have contemplated that agencies

28

should wait multiple years to act pending a consultation's conclusion.

- 16 -

1

Defendants correctly argue that when the current version of Section 7(b) came into

2

effect, formal consultation was limited to assessing the impact of agency action on singular

3

species.20 See AR 0022426–27. The consultations here are "complex nationwide

4

consultations" rather than "discrete, geographically-confined action[s]." Doc. 38 at 20–21.

5

Given the resources required to complete a nationwide consultation, it is arguably

6

infeasible for FWS to complete them within 90 days. Still, as illustrated by the draft BOs

7

on chlorpyrifos and diazinon released for public comment nine months after the EPA

8

initiated consultation, FWS has shown it can complete consultation within a year. See

9

Doc. 35 ¶¶ 11, 15; Doc. 39 ¶¶ 11,15.

10

B. Effects of Delay

11

TRAC factors three and five often overlap and direct the Court to consider the effect

12

of agency delay. In re Ctr. for Biological Diversity, 53 F.4th at 671 (citing In re Barr

13

Laboratories, Inc., 930 F.2d 72, 75 (D.C. Cir. 1991)). Factor three instructs delay is "less

14

tolerable when human health and welfare" are at stake, TRAC, 750 F.2d at 80, and courts

15

have acknowledged ESA-protected species are "valuable to the health and welfare of the

16

nation," In re Am. Rivers & Idaho Rivers United, 372 F.3d 413, 414 (D.C. Cir. 2004); see

17

also Tenn. Valley Auth., 437 U.S. at 178 ("[I]t is in the best interests of mankind to

18

minimize the losses of genetic variations.").

19

The parties contest the extent to which delay in completing consultation is adversely

20

impacting ESA species and habitats under FWS jurisdiction. Plaintiff cites to data in the

21

EPA's original BEs and FWS's draft BOs, all of which are over three and a half years old.

22

See, e.g., Doc. 34 at 33 ("EPA determined that a substantial number of threatened and

23

endangered species and critical habitats are likely to be adversely affected by uses of these

24

pesticides."); Doc. 34 at 35 (citing to EPA BEs and FWS draft BOs completed in 2017 and

25

2021 for data on the percentage of studied species and critical habitats likely to be adversely

26

affected by each pesticide). Defendants argue these figures do not accurately represent

27
20

28

The agencies agreed to pilot the nation-wide consultations in 2014, over 20 years after
the current version of 16 U.S.C. § 1536(b)(1)(A) was enacted. See Act of Nov. 23, 1988,
Pub. L. No. 100-707, 102 Stat. 4689.
- 17 -

1

harm because the cited analyses "assessed a scope of actions under FIFRA that have now

2

significantly changed and no longer reflect the registered uses or other restrictions

3

contained in the label." Doc. 42 at 14.

4

It is true that without current usage information for each pesticide, it is impossible

5

to know the exact extent of the harm they are causing to ESA-protected species and

6

habitats. It is also true that given the mitigation efforts that have occurred in the absence of

7

FWS's Section 7 action, the harm is likely less than predicted by the initiating BEs. But,

8

given the nature of the pesticides' impact on animals and that they are often used

9

concurrently, the harm is more than zero. See Doc. 38 at 31 ("The impacts on listed species

10

and/or designated critical habitats are likely narrower now." (emphasis added)). The

11

prejudice comes from FWS not fulfilling its obligations in the face of unknown harm.

12

Further, as Defendants' arguments show, the pesticides' uses are constantly changing.

13

See, e.g., Doc. 38 at 24 ("Given the fact that the proposed registration actions for

14

chlorpyrifos and diazinon changed (and continued to change) . . . ."); Doc. 42 at 8 ("Given

15

EPA's ongoing registration reviews for these pesticides, there may be more changes to the

16

labels."). The lack of current data and speculation that the BEs overestimated the harm is

17

not enough to balance this factor in FWS's favor. Were the Court to so hold, it would be

18

nearly impossible to ever conclude that the effects of an agency's delay support

19

intervention.

20

Defendants also argue requiring rushed consultations will produce "inferior and

21

indefensible biological opinions that will likely be challenged, resulting in an even further

22

delay" in issuing operative BOs, which is ultimately contrary to Plaintiff's interests.

23

Doc. 38 at 32. This could be true were the Court to grant Plaintiff's initial request and order

24

FWS to complete all the remaining consultations within six months. But Plaintiff no longer

25

seeks a six-month deadline. Defendants have presented the Court with specific dates by

26

which FWS estimates it can complete each BO. By directing FWS to abide by its own

27

timelines, the Court is not ordering rushed opinions but instead ensuring external factors

28

do not further derail the completion of already overdue consultations.

- 18 -

C. Impact on Other Agency Priorities

2

TRAC factor four instructs the Court to consider the impact of judicial interference

3

on higher or competing agency priorities. TRAC, 750 F.2d at 80. Courts are "generally

4

cautious against facilitating line-jumping and reordering agency priorities." In re Ctr. for

5

Biological Diversity, 53 F.4th at 672 (citation omitted). Ordering FWS to complete six

6

complex, nation-wide consultations by Plaintiff's initial six-month deadline would be

7

unreasonable and would disrupt FWS's other functions and priorities. See Doc. 38 at

8

29–30; see also Oceana, 37 F. Supp. 3d at 186 ("[A]n order compelling the agency to issue

9

its BO immediately might undermine the entire process, and arguably have even harsher

10

consequences than any delay."). But Plaintiff is no longer asking for this. Aside from the

11

deadlines for the chlorpyrifos and diazinon consultations, Plaintiff asks the Court to enforce

12

Defendants' own proposed timelines.

13

1. Carbaryl, Atrazine, and Simazine

14

As to the pesticides on which the parties agree to the consultation timeline, Plaintiff

15

is not asking to "cut the line" or force FWS to rearrange its priorities in Plaintiff's favor.

16

Instead, Plaintiff seeks to compel FWS to complete consultation according to its own

17

schedule. See In re Ctr. for Biological Diversity, 53 F.4th at 671 (finding the EPA had

18

unreasonably delayed an effects determination and imposing a deadline "according to [the

19

EPA's] own schedule"). Defendants allege enforcement is unwarranted, in part because the

20

estimated schedule is "ultimately out of its control." Doc. 42 at 5.

21

Defendants' argument is flawed. FWS's unwillingness to commit to a firm deadline

22

is the problem. When asked at oral argument whether their proposed schedule was

23

speculative, Defendants could not assure the Court FWS would meet its deadlines,

24

emphasizing that they were dependent on the EPA and out of FWS's control. Dec. 12, 2024,

25

Oral Arg. Tr. 31:12–32:17. FWS has a history of not abiding by its self-imposed timelines.

26

It has failed to abide by previously agreed to "estimated schedules" for these pesticides,

27

missing some anticipated deadlines by as long as eight years. See Doc. 25 ¶¶ 78, 80;

- 19 -

Doc. 39 ¶¶ 78, 80.21 Courts have previously found similar patterns to weigh in favor of

2

intervention. See NRDC v. U.S. Envtl. Prot. Agency, 798 F.3d 809, 814 (9th. Cir. 2015)

3

(granting a plaintiff's petition for mandamus against the EPA in part because "the agency

4

has a significant history of missing the deadlines it has set in these proceedings"); In re

5

Ctr. for Biological Diversity, 53 F.4th at 672 (ordering the EPA to abide by its proposed

6

deadline and explaining the Court had "reason to doubt whether EPA will meet its own

7

deadline" because the EPA did not commit to a deadline until after the plaintiff sought

8

mandamus, the proposed timeline carried a caveat, and the EPA had no statutory obligation

9

to make the effects determination). FWS has received permission to extend consultation

10

from the EPA and the carbaryl, atrazine, and simazine registrants. With continued

11

permission, FWS has no statutory obligation to meet the proposed deadline.22 Were the

12

Court not to order FWS to abide by its estimated dates, there would be no enforcement

13

mechanism to ensure FWS does not ignore its anticipated completion dates indefinitely.

14

Although FWS surely intends to comply with its estimated timelines in good faith,

15

the Court need not find bad faith to find unreasonable delay. TRAC, 750 F.2d at 80. The

16

Court is aware FWS must balance competing priorities and duties, and circumstances may

17

arise that impact FWS's prioritization of its Section 7 consultations. Still, "[t]he existence

18

and completion of competing priorities does not relieve an agency from progressing with

19

other clearly mandated duties." Brower, 257 F.3d at 1070. "[T]here is a limit to how long

20

[an agency] may use these justifications to excuse inaction." Am. Hosp. Ass'n v. Burwell,

21

812 F.3d 183, 191 (D.C. Cir. 2016) (internal quotation omitted); see also Ctr. For Food

22

Safety v. Regan, 56 F.4th 648, 652 (9th Cir. 2022) (rejecting the EPA's justification for

23

failing to comply with the ESA that it "lacked the resources to do so"). Given Section 7's

24

importance to the ESA's statutory scheme, ordering compliance with FWS's self-imposed

25

21

26
27
28

FWS issued its final methomyl BO and draft carbaryl BO in compliance with the
estimated timelines set forth in this case. Given that this compliance occurred while
litigation was pending, the Court still finds it appropriate to enforce the remaining
deadlines.
22
As discussed in Section III.A.3, the registrants for the various pesticides are unlikely to
oppose further extending the consultation because the EPA has already registered these
pesticides, providing the registrants no incentive to push FWS to complete consultation.
See Doc. 34 at 23 n. 6.

dates best accomplishes the ESA's goals.

2. Chlorpyrifos and Diazinon

3

That judicial enforcement of anticipated deadlines may be necessary does not mean

4

the Court should substitute Plaintiff's judgment for Defendants' expertise on when these

5

consultations can reasonably be completed. See Sierra Club v. Thomas, 828 F.2d 783, 797

6

(D.C. Cir. 1987), superseded by statute on other grounds, Pub. L. No. 101-549, § 707(f),

7

104 Stat. 2399, as recognized in Humane Soc'y v. McCarthy, 209 F. Supp. 3d 280

8

(D.D.C. 2016) ("[A]n agency's control over the timetable of a . . . proceeding is entitled to

9

considerable deference." (internal quotation omitted)). Defendants estimate FWS can

10

complete consultation on chlorpyrifos and diazinon by September 30, 2028. Doc. 38 at 8.

11

The Center seeks to order FWS to complete the consultations by June 30, 2027. Doc. 41

12

at 7. Both parties justify their proposed deadlines based on when the EPA estimates it will

13

complete its supplemental BEs on chlorpyrifos and diazinon: March 31, 2027. See Doc. 38

14

at 16; Doc. 41 at 7. Defendants' timeline is based on their argument that FWS must

15

essentially draft BOs from scratch once it receives the updated information. "[T]he

16

substantial amount of work required to complete these two consultations, the Service's

17

overall anticipated workload in the next four to five years, and its limited budget and staff"

18

explain the longer timeline. Doc. 38 at 16. Plaintiff suggests a date 90 days after the EPA

19

plans to supplement its BEs: the timeline contemplated by 16 U.S.C. § 1536(b)(1)(A). See

20

Doc. 41 at 7. Plaintiff argues that even without the updated BEs, its deadline gives FWS

21

more than two years to consider the EPA's updated insecticide strategy in addition to the

22

years of time already passed. Doc. 41 at 13–14.

23

The Court will defer to FWS's experience on what is a reasonable timeline for

24

issuing the chlorpyrifos and diazinon BOs. See Biodiversity Legal Found., 285 F. Supp.

25

2d at 12 ("[R]espect for the autonomy and comparative institutional advantage of the

26

executive branch has traditionally made courts slow to assume command over an agency's

27

choice of priorities." (quotations omitted)); Grand Canyon Air Tour Coal., 154 F.3d at 460

28

("We defer to the agency's reasonable exercise of its judgment and technical expertise.").

- 21 -

1

The Court agrees the eight-year delay in completing consultation is unreasonable.

2

But Section 7 does call for use of the "best available" data, 50 C.F.R. § 402.14(d), and the

3

EPA has represented that updated data reflecting the actual usage of chlorpyrifos and

4

diazinon is forthcoming, see Doc. 39 ¶ 3. If FWS, in its expertise, estimates it requires 18

5

months to adequately process and reflect that data in its BOs, the Court will defer to its

6

timeline. See Oceana, 37 F. Supp. 3d at 186 (declining to order NMFS to issue a BO on a

7

condensed timeline in part because "critical new data is being analyzed and a premature

8

decision could undermine the time already put in and only threaten NMFS's ability to

9

conduct a thorough and searching analysis") (internal quotations omitted)).

V.

CONCLUSION

11

Defendants have unreasonably delayed completing ESA Section 7 consultations on

12

the pesticides chlorpyrifos, diazinon, carbaryl, atrazine, and simazine in violation of

13

Section 555(b) of the ESA. The Court will order FWS to issue biological opinions on

14

carbaryl, atrazine, and simazine by the parties' mutually agreed upon deadlines provided in

15

Defendants' Motion for Summary Judgment (Doc. 38). The Court will further order FWS

16

to complete consultation and issue biological opinions on chlorpyrifos and diazinon by

17

Defendants' proposed date of September 30, 2028. If FWS is unable to abide by these

18

deadlines, Defendants may petition the Court for modification. The Court will consider

19

modification of these deadlines if FWS documents that extraordinary circumstances not

20

already presented to the court will prevent its compliance. On April 30, 2025, and every

21

180 days thereafter, Defendants shall advise the Court of FWS's progress on these matters.

22

In these status reports, Defendants shall inform the Court whether the EPA is on schedule

23

to provide the information FWS plans to use to inform its BOs.
