Defendants.
SIERRA CLUB’S MOTION FOR PRELIMINARY INJUNCTION
Under Federal Rule of Civil Procedure 65(a), Sierra Club respectfully requests that the Court
issue a preliminary injunction on Complaint Claims for Relief II and III, staying the U.S. Army
Corps of Engineers’ Clean Water Act verifications for the Permian Highway Pipeline, and enjoining
all dredge and fill and any other ground disturbing activities in the Corps’ Action Areas for the
project, which includes 129 separate crossings of waters of the United States under the Corps’
regulatory authority (see App. A to Biological Assessment, Ex. A), for violations of the National
Environmental Policy Act.

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 8 of 45

INTRODUCTION
The U.S. Army Corps of Engineers (“the Corps”) approved the construction of the 428-mile
natural gas Permian Highway Pipeline (“PHP” or “the pipeline”) across 129 waters of the United
States in central Texas without conducting the review required under the National Environmental
Policy Act (“NEPA”), 42 U.S.C. § 4332(C). If completed, the 42-inch diameter pipeline would
transport over 2 billion cubic feet per day of gas from the Permian Basin and would cause (indeed, is
already causing) irreparable harm to some of the most environmentally sensitive streams in central
Texas, including recharge areas of the Edwards and Edwards-Trinity Aquifers, which provide
drinking water for over two million Texans and habitat for many imperiled species. On behalf of its
more than 27,000 members in Texas, many of whom use, enjoy, or depend on those resources,
Sierra Club seeks an order staying the Corps’ Clean Water Act Nationwide Permit 12 (“NWP 12”)
“verifications” for the pipeline and enjoining any further dredge and fill or ground disturbance in the
Corps’ Action Areas until the NEPA process is complete.1
Sierra Club satisfies the standard for a preliminary injunction. First, Sierra Club is likely to
prevail on the merits of its claim that the Corps violated NEPA by failing to conduct the required
environmental review before incorporating the terms and conditions of the U.S. Fish and Wildlife
Service (“FWS” or the “Service”) February 3, 2020 Biological Opinion and Incidental Take
Statement into the Corps’ verifications authorizing dredge and fill activities in 129 separate “waters
of the United States.” As discussed more fully below, courts uniformly have held that “the Corps’
action, by way of adopting and incorporating” the terms of an Incidental Take Statement into a
1

Sierra Club seeks a preliminary injunction only on Claims II and III of its Complaint alleging
violations of NEPA. In this motion, Sierra Club does not seek relief on Claim I, which involves the
April 15, 2020 vacatur of NWP 12 by the United States District Court for Montana for the Corps’
failure to consult with the U.S. Fish and Wildlife Service under Endangered Species Act section 7
prior to issuing NWP 12. Northern Plains Resource Council et. al. v. U.S. Army Corps of Engineers, Case
No. 19-44-GF- BMM (D. Mont. Apr. 15, 2020). The Ninth Circuit denied the Corps’ motion for a
stay of that order pending appeal; on June 15, 2020, however, the United States filed an application
to the U.S. Supreme Court for a stay pending appeal. That application for a stay remains pending.

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 9 of 45

nationwide permit verification “is the functional equivalent of a permit and thus constitutes federal
action subject to NEPA.” Sierra Club v. U.S. Army Corps of Engineers, 803 F.3d 31, 46 (D.C. Cir. 2015).
Second, the Corps’ NEPA violations will cause—indeed, are causing—irreparable harm to
the environment, and to the public’s interest in compliance with NEPA’s environmental and public
review requirements. Third, those irreparable harms outweigh any potential harm to the Corps.
Finally, a preliminary injunction would protect both the public’s interest in the Corps’ compliance
with the law and the Court’s ability to issue meaningful relief after a trial on the merits. Envtl. Def.
Fund v. Marsh, 651 F.2d 983, 1005 (5th Cir. 1981) (holding “[w]hen a court has found that a party is
in violation of NEPA, the remedy should be shaped so as to fulfill the objectives of the statute as
closely as possible, consistent with the broader public interest,” and enjoining a highway
construction project “so that the relevant decision makers and the public may still have the
opportunity to choose among alternatives, as required by NEPA”.).
FACTUAL AND LEGAL BACKGROUND
A. Overview of the Permian Highway Pipeline and its Environmental Impacts
Permian Highway Pipeline LLC is constructing a 428.54 mile-long natural gas pipeline from
the Waha Interconnect in Reeves County, Texas, through the Texas Hill Country, to a delivery point
in Colorado County, Texas. The proposed pipeline will cross numerous permanent and intermittent
waters of the United States, resulting in the discharge of dredged or fill material into approximately
449 separate streams and wetlands along the route. The project will require the construction and
operation of a variety of ancillary facilities associated with the pipeline at each water crossing.
Bulldozers, track hoes, and conventional drilling, boring, and trenching equipment will be used to
clear a 125-foot right-of-way across each stream crossing, dig or bore trenches, and construct the
pipeline.

2

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 10 of 45

The pipeline’s route—which has never been subject to public environmental review or
comment by the Corps or FWS—crosses some of the most environmentally sensitive streams and
geological karst formations in central and west Texas, including recharge zones of the Edwards and
Edwards-Trinity Aquifers, which provide drinking water for over two million Texans and habitat for
many imperiled species listed as “threatened” or “endangered” under the Endangered Species Act.
Due to the unique geological karst features in west and central Texas, most of the aquifer recharge
occurs where overland flow of surfaces waters drains into and through streams, drainage channels,
sinkholes, and other geological fractures or openings into the groundwater. Hayes Decl., Ex. B at 8.
As a result, the dredge and fill activities associated with the Permian Highway Pipeline’s dredge and
fill activities in numerous water crossings creates a significant risk of harm to the aquifer.
Construction of the pipeline began in late February or March 2020. Almost immediately, the
project resulted in a discharge of 36,000 gallons of toxic drilling fluid into the Blanco River during
an apparent attempt to bore under the river. The discharge occurred where the river drains into the
Trinity Aquifer, resulting in immediate contamination of local drinking water wells. Given the many
unique karst geological features of the region, there is a significant risk of similar hazardous
discharges to surface waters as the project progresses. Moreover, sedimentation from dredge and fill
activities, drilling fluid spills, and any petrochemical spills and leaks from diesel and other equipment
will result in direct and immediate loss of irreplaceable surface, groundwater, and aquifer resources.
Id. at 8-9. Once those contaminants are discharged into surface waters and migrate into the
groundwater and aquifer system, they are likely to persist for many months or years, as source of
chemical-laden sediment and turbidity. Id. at 8-9.
The project will also have long-term adverse impacts on vegetation, soil, water and wildlife
in the Corps’ Action Areas, including federally threatened and endangered species and their
habitats—namely, the Houston toad, Golden Cheeked Warbler and Tobusch fishhook cactus. In
3

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 11 of 45

fact, the project will result in a “50-ft permanent easement” across the 428 mile pipeline—totaling
2,604.7 acres—resulting in the permanent destruction of 282 acres of habitat for the endangered
golden cheeked warbler. The project will adversely affect another 1,352.3 acres of warbler habitat,
including 393 acres in waters of the United States subject to the Corps’ jurisdiction. See February 3,
2020 Biological Opinion (“BiOp”), Ex. C at 36-37. The project will also permanently destroy 153.6
acres of habitat for the endangered Houston toad; and adversely affect another 1,293.3 acres,
including 578.9 in waters of the United States subject to the Corps’ oversight. Id. at 37-38.
In addition to the environmental impacts associated with the construction of the Permian
Highway Pipeline, the planned operation of the pipeline carries significant risks for persons along
the route, due to potential leakage and failure of natural gas pipelines, ancillary facilities, and control
valves caused by the accumulation of abrasive particles of iron sulfide and iron oxide mixed with
concentrated hydrocarbons and other contaminants in the pipelines. Hayes Decl., Ex. B at 8.
Accidental spills during pipeline operation and maintenance, or as a result of deteriorating pipelines,
would cause long-term, irreversible environmental contamination due to migration of methane or
other pollutants into surface and groundwater. Id. Natural gas pipelines also contain petrochemical
liquids that can result in spills and sometimes explosions. Hayes Decl., Ex. B at 9. In 2000, for
example, a 30-inch El Paso Natural Gas Pipeline exploded in Carlsbad, New Mexico, killing 12
people and generating a 5,763 square foot crater. The company had failed to properly decant
corrosive and flammable liquids, which accumulated on the lower surface inside the pipe at a low
point along the pipeline. Id. at 9. The catastrophe occurred within a karst aquifer area supporting
federally endangered species, much like the area at issue here. Id.
Although the Corps consulted with FWS about the impacts of the project to endangered
species, the agency failed to conduct any NEPA analysis or provide for public review of the
significant, broader environmental impacts of the project before issuing its Clean Water Act
4

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 12 of 45

verifications to Permian Highway Pipeline LLC to conduct dredge and fill activities in 129 sensitive
waters of the United States, which are subject to the Corps control.
B. The Corps’ Nationwide Permit 12 Verifications Under the Clean Water Act
Because the Permian Highway Pipeline will result in the discharge of fill material into 449
distinct waters of the United States, it was required to obtain a “dredge and fill” permit under
Section 404 of the Clean Water Act, 33 U.S.C. § 1344(a). There are two basic pathways to obtaining
a section 404 “dredge and fill” permit. First, the Corps may issue an individual permit, provided that
there are no practicable alternatives, the discharge does not cause violations of water quality
standards or significant degradation of the environment, and all appropriate steps have been taken
to minimize adverse impacts. 40 C.F.R. § 230.10. When issuing an individual section 404 permit, the
Corps must comply with the requirements of NEPA.
Alternatively, section 404(e) allows the Corps to, issue general or nationwide permits for
categories of dredge and fill activity, which “cause only minimal adverse environmental effects when
performed separately, and will have only minimal cumulative adverse effect on the environment.”
33 U.S.C. § 1344(e)(1). When the Corps issues a nationwide permit, it conducts a “national-scale”
NEPA analysis; and, in most circumstances, subsequent project-specific authorizations under the
nationwide permit do not typically require separate NEPA documentation. 82 Fed. Reg. 1860, 1861
(Jan. 6, 2017).
Rather than apply for a project-specific permit, Permian Highway Pipeline LLC opted to
proceed under NWP 12, which authorizes dredge and fill discharges associated with the
construction of utility lines, including gas pipelines, “provided the activity does not result in the loss

5

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 13 of 45

of greater than 1/2-acre of waters of the United States for each single and complete project.” 82
Fed. Reg. at 1985.2
Under NWP 12’s “self-certification” process, Permian Highway Pipeline LLC would be
authorized to proceed with construction activities in hundreds of those water crossings—
specifically, 330 of the approximately 449 different water crossings—without notifying the Corps.
See 33 C.F.R. §§ 330.1(e)(1), 330.6(a). For the water crossings that “might affect” any species listed
under the Endangered Species Act (“ESA”), however, NWP 12’s General Condition 18 prohibits
any construction activity until the Corps issues a “verification” ensuring that the project complies
with the ESA. 82 Fed. Reg. at 1999-2000. Because approximately 129 of the Permian Highway
Pipeline’s water crossings “might affect” several endangered species—including Golden Cheeked
Warbler, the Houston toad, the Tobusch fishhook cactus, the Austin blind salamander, the Barton
Springs salamander—Permian Highway Pipeline LLC was required to obtain NWP 12 verifications
from the Corps for those water crossings.
C. The Corps’ Endangered Species Act Consultation with the Fish and Wildlife Service
To avoid liability under the Endangered Species Act for any “taking” that results from the
authorization of a specific project under NWP 12,3 the Corps must “insure that any action
authorized, funded, or carried out by [the] agency…is not likely to jeopardize the continued
existence of” any listed species or adversely modify its critical habitat. 16 U.S.C. § 1536(a)(2).

2

On April 15, 2020, the United States District Court for Montana vacated NWP 12 for the Corps’
failure to consult with the U.S. Fish and Wildlife Service under Endangered Species Act (“ESA”)
section 7 prior to issuing the nationwide permit. Northern Plains Resource Council et. al. v. U.S. Army
Corps of Engineers, D. Mont. no. 19-44-GF- BMM (Apr. 15, 2020). As noted, the Ninth Circuit Court
of Appeals denied a stay of that order pending appeal; the Corps has requested a stay from the U.S.
Supreme Court.

The ESA prohibits “any” person, including federal agencies, from “taking” any listed endangered
species, defining “take” as “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or
collect, or to attempt to engage in any such conduct.” 16 U.S.C. §§ 1532(19), 1538(a)(1)(B).
6

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 14 of 45

“Action” is defined broadly to include all activities or programs of any kind authorized, funded, or
carried out by federal agencies, including the issuance of federal permits. 50 C.F.R. § 402.02.
To comply with its obligations under the ESA and NWP 12, the Corps prepared a biological
assessment evaluating whether its authorization of the Permian Highway Pipeline “may affect” any
listed species or designated critical habitat, and whether the agency must therefore initiate formal
Section 7 consultation.4 After determining that approximately 129 of the Permian Highway
Pipeline’s water crossings “may affect” several endangered species, the Corps initiated formal
consultation under Section 7 with FWS.
On February 3, 2020, FWS issued a Biological Opinion concluding that the proposed
action—i.e., the Corps’ proposed verifications—is not likely to jeopardize the continued existence of
any listed species, or adversely modify any designated critical habitat is within the Corps’ “Action
Area” designated by the Service. The Biological Opinion defines the Corps’ “Action Area” as those
portions of the Permian Highway Project that (1) fall under the Corps’ regulatory authority—i.e.,
waters of the United States for which NWP 12 authorization is required—and (2) where the Corps’
proposed NWP 12 verification may affect listed species. BiOp, Ex. C at 10. There are 64 such
Action Areas in the Fort Worth District and 30 such areas in the Galveston district. See Apps. A and
B to Biological Assessment, Ex. A. The Corps’ Action Areas include the crossing and dredge and fill
of approximately 86 Corps’ jurisdictional waters, also known as “waters of the United States,” within
the Fort Worth District and 43 waters of the United States crossings within the Galveston District.
Id. at iii. Together the Action Areas include approximately 2,127 acres in waters of the United States

4

If, after preparing a biological assessment, the action agency finds that the proposed action “may
affect, but is not likely to adversely affect” any listed species or critical habitat and the consulting
agency concurs with this finding, then the informal consultation process is terminated and no formal
consultation is required. 50 C.F.R. § 402.14(b).
7

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 15 of 45

under Corps’ oversight, where the proposed Permian Highway Pipeline is likely to affect endangered
species.
FWS also issued an “Incidental Take Statement” to the Corps, authorizing the “take” of
listed species, subject to “reasonable and prudent measures” that are “necessary or appropriate to
minimize” the impact on the species, and “terms and conditions” that the Corps must comply with to
implement those reasonable and prudent measures. 16 U.S.C. § 1536(b)(4)(i), (ii), (iv); 50 C.F.R. §
402.14(i)(1)(i), (ii), (iv); see also BiOp, Ex. C at 54-57. Specifically, to obtain protection against any
unlawful “taking,” FWS required the Corps to incorporate the “terms and conditions” of the
Incidental Take Statement into its Clean Water Act NWP 12 verifications for the Permian Highway
Pipeline. In fact, FWS’s Biological Opinion and accompanying Incidental Take Statement are not
effective unless and until the Corps issues all required Clean Water Act authorizations for the
project. BiOp, Ex. C at 52.
On February 13, 2020 the Corps issued its final verifications for Project Numbers SWF2018-00227 (Fort Worth District verification, Ex. D) and SWG-2018-00737 (Galveston District
verification, Ex. E). To obtain protection against any unlawful taking, the Corps complied with the
Biological Opinion and incorporated the terms and conditions into its final verifications. In fact, the
Corps’ verifications are explicitly conditioned on compliance with “all project elements” and
“compliance with all of the mandatory terms and conditions” in the Biological Opinion and
Incidental Take Statement, as well as the incorporated biological assessment.5
5

See Fort Worth District verification, Ex. D at 2 (“The terms and conditions of the [Biological
Opinion] that are applicable to [the Corps’] Action Area(s) in the Fort Worth District are
incorporated by reference in this permit. Failure to comply with the terms and conditions that are
applicable to the [Corps’] action area within the Fort Worth District would constitute noncompliance with your . . . permit.”); see also Galveston District verification, Ex. E at 2 (“Your
authorization under this Corps permit is conditional upon your implementing and abiding by all
project elements identified in the enclosed FWS [Biological Opinion] that are subject to the [Corps’]
Action Area(s) and your compliance with all of the mandatory terms and conditions associated with

8

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 16 of 45

FWS’s “terms and conditions” include numerous measures that will have environmental
impacts to Corps jurisdictional waters. Specifically, the terms and conditions include incorporation
of “all” conservation measures described within the Permian Highway biological assessment. The
terms and conditions also incorporate all of the conservation measures included in the Biological
Opinion, such as herbicide and pesticide application measures, oil spill prevention and response
measures, an inadvertent return mitigation plan for horizontal directional drilling, and environmental
awareness training. In addition, the Biological Opinion’s conservation measures include extensive
“void mitigation” measures to protect against impacts to the Edwards aquifer (and the two species
of endangered salamanders), and provides that construction vehicles may cross waters, provides for
bypass pumping and culverts and other measures applicable to water crossings.
Additionally, the Biological Opinion’s “conservation measures” requires Permian Highway
Pipeline to purchase 1,363 acres for mitigation habitat for the golden cheeked warbler and transfer it
to the Service; to avoid construction activities in the warbler habitat between March 1, 2020 and July
31, 2020, but allowing construction activities adjacent to it; and to implement Oak wilt prevention
measures such as not cutting oak trees from February through June. It also involves fencing and
monitoring for the Houston toad and collection and translocation of the Tobusch fishhook cactus
before construction.6
Despite these environmental impacts and risks, the Corps did not conduct any NEPA
analysis for its decision to adopt and incorporate the terms and conditions of the Biological Opinion
into the Clean Water Act NWP 12 verifications for the Permian Highway Pipeline. Nor did the

which terms and conditions are incorporated by reference in this permit. Failure to comply with the
terms and conditions that are applicable to the [Corps’] action area within the Galveston District
would constitute non-compliance with your . . . permit.”
6

On May 4, 2020, the Service issued an Addendum to the Biological Opinion with additional terms
and conditions. See Addendum to BiOp, Ex. J.

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 17 of 45

agency disclose any of those impacts to the public or invite comment on alternatives or other
measures that would avoid or further mitigate any environmental impacts.
PRELIMINARY INJUNCTION STANDARD
“A preliminary injunction may be issued to protect the plaintiff from irreparable injury and to
preserve the district court’s power to render a meaningful decision after a trial on the merits.” Canal
Auth. of State of Fla. v. Callaway, 489 F.2d 567, 572 (5th Cir. 1974). To obtain a preliminary injunction,
the movant must establish “(1) a substantial likelihood of success on the merits, (2) a substantial
threat of irreparable injury if the injunction is not issued, (3) that the threatened injury if the
injunction is denied outweighs any harm that will result if the injunction is granted, and (4) that the
grant of an injunction will not disserve the public interest.” Texans for Free Enter. v. Tex. Ethics
Comm’n, 732 F.3d 535, 536-37 (5th Cir. 2013).
ARGUMENT
A. Sierra Club is Likely to Succeed on the Merits of Its Claim that the Corps’
Implementation of a Biological Opinion and Incidental Take Statement Through Clean
Water Act Verifications is Subject to NEPA.
To protect, restore, and enhance the quality of the human environment, NEPA requires all
federal agencies government to identify and fully assess the impacts of any “major Federal actions
significantly affecting the quality of the human environment,” 42 U.S.C. § 4332(2)(C), “before
decisions are made and before actions are taken.” 40 C.F.R. § 1500.1(b) (emphasis added). Major
federal actions include projects that are “potentially subject to Federal control and responsibility” or
“regulated, or approved by federal agencies,” including construction projects that are “approved by
permit or other regulatory decision as well as federal and federally assisted activities.” 40 C.F.R. §
1508.18. A major Federal action occurs “whenever an agency makes a decision which permits action
by other parties which will affect the quality of the environment.” Humane Soc. of U.S. v. Johanns, 520
F. Supp. 2d 8, 22 (D.D.C. 2007).

10

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 18 of 45

NEPA’s mandate, which incorporates detailed notice and comment procedures, serves the
“twin purposes of ensuring that (1) agency decisions include informed and careful consideration of
any environmental impact, and (2) agencies inform the public of that impact and enable interested
persons to participate in deciding what projects agencies should approve and under what terms.”
Sierra Club v. U.S. Army Corps of Engineers, 803 F.3d at 36-37 (citation omitted).
At the heart of NEPA is a requirement that the agency take a “hard look” at all relevant
environmental impacts and potential alternatives to the proposed action, and it must provide public
notice and an opportunity to comment before the agency decides whether and how to proceed. 40
C.F.R. § 1508.9; see also Robertson v. Methow Valley Citizens Council, 490 U.S. 332, 349 (1989) (The
NEPA analysis “ensures that important effects will not be overlooked or underestimated only to be
discovered after resources have been committed or the die otherwise cast.”); see also Envtl. Def. Fund
v. Marsh, 651 F.2d at 997 (“NEPA requires the discussion of all significant environmental impacts,
not just adverse ones.”).
Indeed, “public scrutiny [is] essential,” 40 C.F.R. § 1500.1(b), and the agency must “[m]ake
diligent efforts to involve the public” in preparing the relevant environmental documents by
disclosing sufficient information to meaningfully understand and comment on any environmental
impacts, and help develop alternatives that may mitigate or avoid impacts of the proposed federal
action. 40 C.F.R. §§ 1500.2(d), 1501.4, 1506.6; see also Methow Valley, 490 U.S. at 349 (NEPA “gives
the public the assurance that the agency “has indeed considered environmental concerns in its
decisionmaking process,” . . . and, perhaps more significantly, provides a springboard for public
comment.”) (citation omitted).
Here, there is no dispute that the Corps failed to conduct any NEPA analysis before
adopting and incorporating the terms and conditions of the February 3, 2020 Biological Opinion
into the Clean Water Act NWP 12 verifications, which authorize the Permian Highway Pipeline to
11

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 19 of 45

conduct dredge and fill activities in 129 discrete segments of the “waters of the United States” and
associated Action Areas within the Corps’ jurisdiction. The Corps therefore failed to evaluate the
direct, indirect, and cumulative environmental impacts of these terms and conditions. This
includes a failure to evaluate any alternatives, including a “no action” alternative, or mitigation
measures that might avoid those risks. Perhaps more significantly, the Corps failed to disclose any
of those risks to the public, or engage in any public review process, as required NEPA.
Although the issuance of a NWP 12 verification, standing alone, does not typically require
separate NEPA documentation (because the Corps conducted an environmental assessment when
the agency issued the nationwide permit), 82 Fed. Reg. at 1861, courts have uniformly held that a
federal action agency’s discretionary decision to “implement[]” a biological opinion itself, or its
decision “adopting and incorporating” the terms of a biological opinion “through its Clean Water
Act verification constitutes federal action subject to NEPA.” Sierra Club v. U.S. Army Corps of
Engineers, 803 F.3d at 46; see also San Luis & Delta-Mendota Water Auth. v. Jewell, 747 F.3d 581, 642 (9th
Cir. 2014) (holding that the Bureau of Reclamation's “implementation” of a biological opinion
issued by the National Marine Fisheries Service was a major federal action pursuant to 40 C.F.R. §
1508.18); In re Consolidated Salmonid Cases, 688 F. Supp. 2d 1013, 1025 (E.D. Cal 2010) (same);
Wyoming Outdoor Council v. U.S. Corps of Engineers, 351 F. Supp. 2d 1232, 1242 (D. Wyo. 2005) (in a
challenge to the Corps’ issuance of a general dredge and fill permit under the Clean Water Act,
concluding that NEPA analysis was required because the Corps’ was the “gatekeeper for approval of
the project,” and the agency’s approval was “essential to completion of the project”); Fath v. Texas
Dep’t of Transp., 2016 WL 7442868 at *6 (W.D. Tex. Sept. 6, 2016) (citing Sierra Club v. U.S. Army
Corps of Engineers, 803 F.3d at 40 with approval and concluding that plaintiffs sufficiently stated a
NEPA claim against Texas Department of Transportation where the state agency was “acting in the

12

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 20 of 45

capacity of a federal agency” in implementing the terms of a Biological Opinion in the construction
of a federally-approved, federally-funded highway).
The D.C. Circuit’s opinion in Sierra Club v. U.S. Army Corps of Engineers is instructive. In that
case, the plaintiffs argued that FWS’s issuance of an incidental take statement, or alternatively, the
Corps’ implementation of that incidental take statement into the NWP 12 verifications for the
“Flanagan South” oil pipeline, required a NEPA analysis for the entirety of the entire 593-mile-long
project. 803 F.3d 31. The court rejected the plaintiffs’ first argument, concluding the “development
and issuance of the Section 7 [Incidental Take Statement], standing alone, was not federal action”
subject to NEPA. Instead,
[i]t was only when the Corps formally incorporated the [incidental take statement]
into its Clean Water Act verifications that it gave [the permittee] permission to take
species free from the threat of ESA liability. The Corps-implemented [incidental take
statement] is the functional equivalent of a permit and thus constitutes federal action
subject to NEPA.
Id. at 45. Thus, under the plain terms of 40 C.F.R. § 1508.18, the Corps final action “adopting and
incorporating” the terms and conditions of an incidental take statement into a Clean Water Act
verification (as the agency did here with the Permian Highway) constitutes a major federal action
subject to review under NEPA. The agency’s NEPA obligations arising out of that action, however,
“extend[] only to the segments under the Corps’ asserted Clean Water Act jurisdiction.” Id. at 46-47
(emphasis added).
That is precisely the claim Sierra Club advances here: The Corps’ decision to implement and
incorporate the terms and conditions of the February 3, 2020 Biological Opinion into the Permian
Highway’s Clean Water Act NWP 12 verifications was a major federal action triggering NEPA. The
verifications, on their face, constitute a regulatory “authorization”—indeed, a requirement—to
implement the “all project elements” outlined in the Biological Opinion and Incidental Take
Statement, Galveston Verification at 2, many of which are “specific projects” requiring additional
13

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 21 of 45

“construction or management activities located in a defined geographic area.” 18 U.S.C § 1508.18; see
also Galveston Verification, Ex. E at 2 (Permian Highway Pipeline’s Clean Water Act “authorization
under this [Corps’] permit is conditioned upon you implementing and abiding by all project
elements” in the Biological Opinion and Incidental Take Statement in the Corps’ Action Areas). The
Biological Opinion additionally requires the implementation of all measures included in the
underlying Biological Assessment. BiOp, Ex. C at 56. And the Permian Highway Pipeline’s “failure
to comply with” those mandatory terms and conditions “would constitute non-compliance” with the
verifications and “invalidate[] the incidental take authorization.” Id. at 2. Because the Corps’
verifications are “the functional equivalent” of the final federal authorization of the specific projects
identified in the Biological Opinion, Incidental Take Statement, and Biological Assessment, the
Corps was required to comply with NEPA. Sierra Club v. U.S. Army Corps of Engineers, 803 F.3d at 45.
The Corps’ adoption of the Biological Opinion’s terms and conditions constitutes a major
federal action for an additional and independent reason. The Biological Opinion sets out the terms
and conditions with which the Corps must comply to avoid any unlawful taking under the ESA,
BiOp, Ex. C at 52; and by incorporating “all project elements” of the BiOp into the verifications,
the Corps committed itself to implement and comply with those terms. Specifically, the Corps “has
a continuing duty to regulate” the Permian Highway Pipeline activities in the Action Areas, id. at 52,
and “shall” ensure that the measures identified in the BiOp—including, water conservation
measures, sediment control, construction and clearing restrictions, and compliance with “all” species
and conservation measures—are actually implemented. Id. at 55-56. The Corps was not obligated to
take final action issuing the verifications; but in doing so, the Corps took a discretionary major
federal action subject to NEPA.
In sum, the Corps’ adoption and “incorporat[ion]” of FWS’s February 3, 2020 Biological
Opinion’s “mandatory terms and conditions” into the Permian Highway Pipeline’s Clean Water Act
14

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 22 of 45

NWP 12 verifications constitutes a major federal action within the plain meaning of 40 C.F.R. §
1508.18. Accordingly, the agency was required to fully evaluate the environmental impacts
authorizing the Permian Highway Pipeline to conduct dredge and fill activities in discrete “waters of
the United States,” that comprise the Corps’ Action Area.7
B. There Will Be Immediate and Irreparable Harm to the Environment, Sierra Club’s
Members’ Interests, and the Public in the Absence of an Injunction.
Plaintiffs must demonstrate “that [it] is likely to suffer irreparable harm in the absence of
preliminary relief.” Software Dev. Techs. v. TriZetto Corp., 590 F.App’x 342, 344 (5th Cir. 2014) (citing
Winter v. Natural Res. Def. Council, Inc., 555 U.S. 7, 20 (2008)). In this case the injury is not only likely,
it is underway. Permian Highway Pipeline, LLC (“PHP LLC”) began clearing and construction of
the pipeline in February 2020. City of Austin v. Kinder Morgan Texas Pipeline, LLC, No. 1:20-CV-138RP, 2020 WL 1324071, at *6 (W.D. Tex. Mar. 19, 2020).
The impacts of this clearing and construction constitute irreparable harm and support a
preliminary injunction. See U.S. v. Marine Shale Processors, 81 F.3d 1329, 1360 (5th Cir. 1996)
(“Environmental injury, by its nature, can seldom be adequately remedied by money damages and is
often permanent or at least of long duration, i.e., irreparable. If such injury is sufficiently likely,
therefore, the balance of harms will usually favor the issuance of an injunction to protect the
environment.”) (quoting Amoco Prod. Co. v. Vill. of Gambell, 480 U.S. 531, 545 (1987); see also Sierra Club
v. Peterson, 185 F.3d 349, 374 (5th Cir. 2000), vacated on other grounds 228 F. 3d 559 (5th Cir. 2000)
(granting preliminary injunction to stop Forest Service even-aged timber management practices
threatening the environment).

7

Sierra Club’s limited request for relief in the instant case on the Corps’ water crossings only
distinguishes this from the Flanagan South case where the plaintiffs were denied relief because they
sought to enjoin the pipeline “as a whole.” Sierra Club v. U.S. Army Corps of Engineers, 803 F.3d at 4647.
15

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 23 of 45

1. The Corps’ NEPA Violation and Lack of Public Participation Constitute Continuing
Irreparable Harm
A “procedural injury” arising from a NEPA violation, coupled with concrete injury to
aesthetic, environmental, property, or other protected interests, is sufficient to demonstrate
irreparable harm. Fund for Animals v. Norton, 281 F. Supp. 2d 209, 222 (D.D.C. 2003); Fund for
Animals v. Clark, 27 F. Supp. 2d 8, 14 (D.D.C. 1998); and see Sierra Club v. Marsh, 872 F.2d 497, 500
(1st Cir. 1989) (Breyer, J.) (“[W]hen a decision to which NEPA obligations attach is made without
the informed environmental consideration that NEPA requires, the harm that NEPA intends to
prevent has been suffered.”). “[T]he ‘risk implied by a violation of NEPA is that real environmental
harm will occur through inadequate foresight and deliberation’ by the acting federal agency.” Catron
Cty. Bd. of Commissioners v. U.S. Fish & Wildlife Serv., 75 F.3d 1429, 1433 (10th Cir. 1996) (quoting
Marsh, 872 F.2d at 504); see also Found. On Econ. Trends v. Heckler, 756 F.2d 143, 157 (D.C. Cir. 1985)
(“the lack of an adequate environmental consideration looms as a serious, immediate, and
irreparable injury”).
The harm from the Corps’ NEPA violation in this case is real. Because it did no analysis on
implementation of the Services’ terms and conditions, the Corps did not consider the direct,
indirect, and cumulative impacts of its action or take the “hard look” at these impacts that NEPA
requires. See 40 C.F.R. §§ 1502.1, 1502.16(a)-(b), 1508.7, 1508.25(c). And, the Corps did not provide
the public notice and opportunity to comment on its action that NEPA requires under 40 C.F.R. §§
1503.1(4) and 1506.6. Had the Corps done so, the public could have provided comments leading the
agency to modify its decision or adopt alternatives that could mitigate or eliminate environmental
harm. 40 C.F.R. §1503.4(a); see also Methow Valley, 490 U.S. at 349 (NEPA “gives the public the
assurance that the agency “has indeed considered environmental concerns in its decisionmaking

16

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 24 of 45

process,” . . . and, perhaps more significantly, provides a springboard for public comment.”)
(citation omitted).8
Plaintiffs’ members would have participated in the NEPA process given the chance, and
would participate the future. See Frantzen Decl., Ex. F ¶ 4; Gates Decl., Ex. G ¶ 3; see also Hayes
Decl., Ex. B ¶¶ 55-56 (describing information that could have been provided to the Corps through
public participation in the NWP 12 verification and NEPA processes if allowed).
The ongoing harm from the Corps failure to provide for public participation impacts not
just Plaintiffs, but the public at large. Cf. Sierra Club v. Johnson, 436 F.3d 1269, 1279 (11th Cir. 2006)
(finding procedural injury standing where agency use of required mailing list could have led to
additional public input and improvements in the project); and U.S. Steel Corp. v. EPA, 595 F.2d 207,
212-15 (5th Cir. 1979) (failure to follow public participation requirements of the Administrative
Procedure Act renders agency action invalid). In sum, the Corps’ NEPA violations, its uninformed
decision on its verifications, and its denial of public participation and comment constitute
continuing irreparable harm.9

8

The Council on Environmental Quality regulations require a give and take between an agency and
members of the public in the NEPA process. See 40 C.F.R. §§ 1500.1(b) (2010) (“public scrutiny [is]
essential”), 1500.2(d) (2010) (the agency must “encourage and facilitate public involvement”), 1506.6
(2010) (the agency must “[m]ake diligent efforts to involve the public” in preparing environmental
documents, give “public notice of . . . the availability of environmental documents so as to inform
those persons ... who may be interested or affected,” and “solicit appropriate information from the
public.”). The regulations require federal agencies to give the public as much information as is
practicable, so that the public has a sufficient basis to comment on, and address, the factors that the
agency must consider in preparing an environmental assessment. 40 C.F.R. § 1501.4 (2010).
9

The Services’ Biological Opinion does not excuse the Corps’ violations. No notice or opportunity
for comment is given on the BiOp. And because the Services’ ESA analysis is narrower than a
NEPA analysis, it is no substitute for a NEPA analysis. Ramsey v. Kantor, 96 F.3d 434, 443 (9th Cir.
1996); San Luis & Delta-Mendota Water Auth. v. Jewell, 747 F.3d 581, 649-50 (9th Cir. 2014); Malama
Makua v. Rumsfeld, 163 F. Supp. 2d 1202, 1218 (D. Haw. 2001) (a “no jeopardy” finding is not the
equivalent of a no significant impact finding under NEPA).

2.

Irreparable Harm from Construction

a. Construction impacts throughout route including the Corps Action Areas
The Service’s Biological Opinion makes clear that there will be irreparable harm to the
environment from the permanent clearing, construction, and operation of the pipeline right-of-way
along its 428.54-mile route, including clearing and constructing the right-of-way through the
project’s hundreds of water crossings, as authorized by the Permian Highway Pipeline verifications.
See BiOp, Ex. C at 37-40. The typical right-of-way is 125 feet and is comprised of a 50-foot permanent
easement, and a 75-foot temporary construction easement, with 330-foot, 500-foot, and 984-foot
offsets for the golden cheeked warbler and Tobusch fishhook cactus, Houston toad, and the Austin
blind salamander and the Barton Springs salamander, respectively. Id. at 9. The project will also
require the construction of permanent pump-related facilities, grading, excavation, the clearing of
trees, vegetation and ground cover, mulching, pesticide and herbicide application, topsoil stripping,
digging, dewatering, and modifications to existing private roads and stream crossings. Id. at 7-15.10
The Corps’ Biological Assessment describes additional permanent impacts. See Biological
Assessment, Ex. A. Specifically, a “50-ft permanent easement” will be established and maintained
upon completion of construction and during operation, with regular removal of brush and trees to
prevent it from growing back. Id. at 69; BiOp, Ex. C at 12, 14. The right-of-way for the project will
involve the total permanent disturbance of 2,604.7 acres. Biological Assessment, Ex. A at 5.
Permanent ancillary facilities will permanently disturb 178.1 additional acres. Id. at 6.

The project began clearing warbler habitat shortly after this court denied a temporary restraining
order on February 14, 2020 in City of Austin v. Kinder Morgan Texas Pipeline LLC, No. 1:20-CV-138-RP
(Doc. 31). See Order Denying Preliminary Injunction at 10, City of Austin v. Kinder Morgan Texas
Pipeline LLC, No. 1:20-CV-138-RP (Mar. 19, 2020) (Doc. 59). Based on the BiOp, this means the
pipeline construction would not be completed until February, 2021. Permian Highway Pipeline LLC
stated three warbler areas had not been cleared by the March 1, 2020 shut-down date for the habitat.
(Id. at Doc. 54-1). Habitat clearing in these locations will not occur until after the August 1, 2020
limitation on warbler habitat clearing and “shall be completed by February 28, 2021.” See Addendum
to BiOp, Ex. J at 2.

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 26 of 45

The construction of the pipeline will also cause irreparable harm to the aquatic environment,
including the discharge of dredged or fill material into 449 waters of the United States. Biological
Assessment, Ex. A at 1. Of those proposed crossings, 129 are in the Corps’ designated “Action
Areas” and require verifications from the Corps under Nationwide Permit 12. Id. at 1. As a result of
the project, and the incorporation of the biological assessment and BiOp, construction vehicles will
cross waters, which will cause rutting and sedimentation, and that construction through the waters
involves bypass pumping, diverting water from streams, building culverts and other measures
adversely affecting water quality and quantity. See App. C to Biological Assessment, Ex. A at 192; see
also Hayes Decl., Ex. B ¶¶ 22-23, 25. These water crossings will result in numerous and significant
environmental impacts, including adverse impacts to riparian productivity, water quality, disruption
of flow pathways that link groundwater and surface water, alteration of the hydrostatic equilibrium,
subsidence, bank destablization, erosion, sedimentation, and boating and swimming hazards. Hayes
Decl., Ex. B ¶¶ 21-22; see also Blair Decl., Ex. H ¶ 7.
In addition, the project would use horizontal directional drilling in ten areas, including the
crossing of seven major Texas rivers, including two crossings of the pristine Blanco River in the
“interconnected contributing recharge zones of the Trinity and Edwards Aquifers.” Biological
Assessment, Ex. A at 2, 24.11 Horizontal directional drilling is a method by which the pipeline
company drills under the river and runs the pipeline through it. It can result in an inadvertent return
of drilling fluid to the overlying water and result in increased sedimentation and turbidity, which
would affect aquatic biota. See Hayes Decl., Ex. B ¶¶ 34-36; Watson Decl., Ex. I ¶ 4. The unique
karst geological features of the Trinity and Edwards Aquifers allow for the “rapid infiltration” from
surface waters, which “strongly influences the flow of water within major springs,” such as Barton,
San Marcos, and Jacob’s Well Springs. Biological Assessment, Ex. A at 24.
11

Of these seven crossings, six are in the Fort Worth District, and one is in the Galveston District.
Biological Assessment, Ex. A at 2.

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 27 of 45

A portion of the Permian Highway Pipeline will also traverse the Balcones Escarpment
including the interconnected contributing and recharge zones of the Trinity and Edwards aquifers.
App. C to Biological Assessment, Ex. A at 191. Both aquifers are of conservation concern due to
their hydrologic function, ecological significance, and vulnerability to contamination. Id. The project
crosses, and will require permanent dredge and fill activity, through 23 miles in the Trinity Aquifer
recharge zone and 12 miles in the Barton Springs Segment of the Edwards Aquifer. BiOp, Ex. C at
2. Rapid recharge to the aquifers occurs through sensitive karst features such as caves, solution
cavities, and sinkholes. App. C to Biological Assessment, Ex. A at 191. These features also provide
recharge to springs, recreational opportunities for swimmers, or a source of drinking water. Id.
Damage to these sensitive karst features could result in interruption to groundwater flow paths that
contribute to aquatic habitat and minimize the potential for sediment and other pollutants to enter
the Edwards Aquifer and degrade aquatic habitat. Id. In fact, the project has already resulted in
spilled drilling fluid in the karst areas, which led to the contamination of local drinking water wells.
See Blair Decl., Ex. H ¶ 7; Watson Decl., Ex. I ¶ 5.
As a result of the permanent clearing and construction of the pipeline and associated
permanent right-of-way, which crosses 129 waters of the United States in the Action Areas subject
to the Corps’ jurisdiction, the Permian Highway Pipeline is already causing, and will continue to
cause, irreparable harm to surface, groundwater, and drinking water resources, forests, soils, and
vegetation, and wildlife and habitat See BiOp, Ex. C at 37-40.
b. Additional impacts specific to the Corps’ Action Areas including impacts of implementing
the Service’s Terms and Conditions
In addition to harms associated with the permanent impacts to the Corps’ Action Areas
from the construction of the pipeline and right of way, the implementation of the Biological
Opinion and its associated terms will result in additional, permanent impacts to the environment
that have never been subject to NEPA review. The Service’s Biological Opinion defines the Corps’
20

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 28 of 45

“Action Areas” as those where the Corps is basing its water crossings on General Condition 18 of
NWP 12, which applies where threatened and endangered species will be impacted, and the
surrounding impacted areas. BiOp at 10. There are 64 such areas in the Fort Worth District and 30
such areas in the Galveston district. See App. B to Biological Assessment, Ex. A. These Action Areas
include the crossing and dredge and fill of 86 distinct waters of the United States within the Fort
Worth District, and another 43 distinct water segments or wetlands under the Corps’ jurisdiction in
the Galveston District. See Biological Assessment, Ex. A at iii.12
As noted, the Biological Opinion identifies numerous environmental impacts from
construction in the Corps’ Action Areas including vegetation clearing (including maintaining the
permanent right-of-way), herbicide application, machinery oil spills and water crossings, in addition
to the trenching, blasting and general construction impacts. Id. FWS’s Addendum to the Biological
Opinion includes a description of additional environmental consequences of the project, including
the sustained extreme noise of the pipeline construction from blasting, engines and excavating. See
May 4, 2020 FWS Addendum to BiOp, Ex. J. None of these impacts have been subject to NEPA
review.
Moreover, to address the project’s impacts to endangered species in these Action Areas, the
Service’s Incidental Take Statement includes numerous terms and conditions that will have additional
environmental impacts, which, like the impacts of the pipeline itself, have likewise never undergone
NEPA review. To avoid liability for unlawful taking of endangered species associated with the
issuance of the verifications, the Service required the Corps to incorporate these “terms and
conditions” of the Incidental Take Statement into its verifications. BiOp at 52. And to obtain

12

For identification of the water crossings in the Galveston Corps’ Action Areas, see App. B, sheets
77-92 to Biological Assessment, Ex. A; and for the Fort Worth Corps’ Action Areas, see sheets 1-77.
The water crossing where Permian Highway Pipeline intends to use horizontal directional drilling
methods are in sheets 33, 37, 48, 58, 59, 67, 71, 79 and 88.
21

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 29 of 45

Section 7 protection, the Corps decided to incorporate the terms and conditions into its final
February 13, 2020 verifications. Fort Worth Verification, Ex. D at 2; Galveston Verification, Ex. E
at 2.
The Incidental Take Statement also provides that “[a]ll conservation measures described
within the [Biological Assessment] dated August 2019, and this [BiOp] shall be fully implemented.”
BiOp, Ex. C at 55. Those measures include “vegetation clearing” “[w]ithin [golden cheeked warbler]
habitat in [the Corps’] Action Area.” Id. at 55. Vegetation clearing includes cutting down trees,
shrubs and all vegetation in the right-of-way down to the soil, and maintaining this right-of-way
permanently so it does not grow back. Id. at 14; see also Blair Decl., Ex. H ¶ 4 (describing irreparable
harm to forest, soil and wildlife from vegetation clearing).
The Biological Opinion identifies numerous additional adverse impacts, including herbicide
and pesticide application; oil spills from heavy machinery impacting soil and water; and “inadvertent
return” of drilling fluids impacting soil and water in the horizontal directional drilling process. BiOp,
Ex. C at 10. The BiOp also discusses potential “void” harm, e.g. release of fluids into the karst
formation. Id. at 3. Indeed, such a spill occurred on March 28, 2020, contaminating nearby wells and
prompting Hill County to halt construction to protect public health and the environment. See
Attach. B to Blair Decl., Ex. H; Watson Decl., Ex. I at 4, 5. The toxic and chemical-laden sediment
resulting from that spill are likely persist for months, if not years, and threaten to permanently
degrade water quality in the Edwards aquifer (and the two species of endangered salamanders).
Hayes Decl., Ex. B ¶¶ 27, 36, 41; Blair Decl., Ex. H ¶ 7; Watson Decl., Ex. I ¶¶ 4, 5; see also BiOp,
Ex. C at 3 (referencing App. C to Biological Assessment). These conservation measures purport to
“minimize” those impacts, but they do not ensure there will be no harm. BiOp, Ex. C at 3.
The Biological Opinion and addendum also require numerous, additional construction
measures designed to reduce impacts to engendered species, including seasonal restrictions on
22

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 30 of 45

construction activities, the purchase and transfer of conservation credits and mitigation lands, wilt
oak fungus prevention measures, additional vegetation clearing and revegetation measures, and
construction of fencing, drive-over gates, and sediment barriers. BiOp, Ex. C at 10-15, 55-57; FWS
Addendum to BiOp, Ex. J. These measures not only make clear that pipeline construction in the
Action Areas will, by itself, result in significant permanent environmental impacts that were never
subject to NEPA review, but that the Biological Opinion’s terms and conditions will themselves have
(and are having) additional environmental impacts that also have never been subject to public
review. See, e.g., Blair Decl., Ex. H (detailing and memorializing stream, forest, soil, and wildlife
impacts from ongoing vegetation clearing and construction).
3.

Irreparable Harm to Plaintiff’s Members
Sierra Club members, including numerous residents of Hill County in central Texas, have

property, business, recreational, aesthetic, and environmental interests that are being and will be
irreparably harmed by the Corps implementation of the BiOp’s terms and conditions, including
clearing and construction of the pipeline, associated water crossings, and dredge and fill allowed by
the Corps. See Decl. of Heath Frantzen, Ex. F; Decl. of Susan Gates, Ex. G; Decl. of John Watson,
Ex. I; Decl. of Belinda Pence, Ex. L; Decl. of Lynn Gallimore, Ex. K.13
The Permian Highway pipeline will directly cross property owned by Sierra Club member
Heath Frantzen. Frantzen Decl., Ex. F ¶ 4. The property has been in his family for generations, and
is comprised of a trophy deer hunting ranch with an emphasis on conservation. Id. ¶¶ 2, 4. His use
and enjoyment of the property will be diminished by the pipeline construction process, and an

These declarations also demonstrate Plaintiff’s standing to sue. See Lujan v. Defenders of Wildlife, 504
U.S. 555, 572 n.7 (1992) (member of public living near site for a proposed dam would have
procedural standing to challenge the agency’s failure to prepare an EIS); Int’l Broth. of Teamsters v. U.S.
Dept. of Transp., 714 F.3d 580 (D.C. Cir. 2013); Ouachita Watch League v. Jacobs, 463 F.3d 1163,1170-72
(11th Cir. 2006) (cognizable procedural injury exists when NEPA not followed and Plaintiffs’
interests are threatened by the action).

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 31 of 45

explosion or leak during the pipeline operation would damage his land and business. Id. ¶ 9. The
pipeline will cross the Pedernales River roughly ten miles upstream from Mr. Frantzen’s property. Id.
¶ 5. The water that Mr. Frantzen relies on for both his household needs and for his herd comes
from two wells on his property. Id. ¶ 9. He is concerned that damage done to the underlying karst
aquifer will impact the wells on his property, as they are easily permeated and damaged, which can
lead to contamination of the aquifer. Id. If the pipeline is built and there is a gas leak, it could reach
the river and harm both water quality and wildlife. Id. ¶ 8. In addition, Mr. Frantzen and his family
have prioritized maintaining habitat on his land for the golden-cheeked warbler, as they are
important to both him and his guests. Id. ¶ 7. Mr. Frantzen has also attended local meetings to
discuss the damage that could occur to the region if the Permian Highway pipeline is constructed in
Hill Country. Id. ¶ 11.
Like Mr. Frantzen, John Watson is a landowner along the Pedernales River downstream of
the pipeline crossing and is concerned about the impact it will have on his ability to enjoy the river
and the many recreational opportunities it creates. Watson Decl., Ex. I ¶ 4, 5. Mr. Watson walks
along the river on his property often, spending time fishing, swimming, and recreating with his
children and grandchildren on the river. Id. The plan to use horizontal directional drilling to go
under the Pedernales could cause problems with water quality since the methods they use could
cause drilling fluids to reach the water above and below, as evidenced by the construction shut down
in Blanco County. Id. ¶ 5.
Lynn Gallimore, a resident of Wimberley, Texas, lives along Lone Man Creek, which is
crossed by the Permian Highway pipeline less than a mile upstream from her home and business.
Gallimore Decl., Ex. K ¶ 2. Like many of the other landowners along the route, Ms. Gallimore is
concerned about the construction of the pipeline through the easily damaged karst in the region. Id.
¶ 4. If the pipeline were to puncture the karst aquifer upstream, the water that flows into Lone Man
24

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 32 of 45

Creek could be diverted underground or contaminated. Id. Lone Man Creek is used by Ms.
Gallimore and her guests for fishing, swimming, and other recreational pursuits. Id.
Susan Gates, a resident of Driftwood, Texas for 21 years, and Belinda Pence, a resident of
Fredericksburg, Texas, regularly take walks in their respective neighborhoods that would be greatly
diminished by pipeline construction. Gates Decl., Ex. G ¶¶ 1, 6; Pence Decl., Ex. L ¶¶ 1, 4. Ms.
Gates lives less than a mile and a half from the pipeline route, with the only entrance to her
subdivision less than ¼-mile from the pipeline. Gates Decl., Ex. G ¶ 6. Ms. Pence lives less than
500-feet from the pipeline route. Pence Decl., Ex. L ¶ 4. The clearing, construction, and operation
of the pipeline will impact their experience through noise pollution, possible methane leaks, and the
permanent maintenance of the pipeline easement, thus diminishing the enjoyment they get from this
time spent outdoors. Id. ¶¶ 4-6; Gates Decl., Ex.G ¶¶ 6, 7. The clearing and construction will also
affect the warbler habitat and scare off individuals, which impacts them since the presence of the
golden-cheeked warbler is something that both cite as reasons for their walks, as they can often be
spotted along the route. Gates Decl., Ex. G ¶ 6; Pence Decl., Ex. L ¶ 4.

Impacts to Endangered Species
The impacts of the “terms and conditions” that must be considered in the Corps’ NEPA

analysis include numerous measures that will have immediate and irreparable impacts to Corps
jurisdictional waters, the Corps’ Action Area and Sierra Club members, in addition to their effects on
the endangered species. This motion is therefore different from the motions for temporary
restraining order and preliminary injunction in City of Austin v. Kinder Morgan Texas Pipeline, LLC,
supra, where this Court denied the requested injunction based on a finding of lack of irreparable
harm to the endangered species. See February 14, 2020 Order Denying Motion for Temporary
Restraining Order at 4, 6-7, City of Austin v. Kinder Morgan Texas Pipeline LLC, No. 1:20-CV-138-RP
(Doc. 31); March 19, 2020 Order Denying Motion for Preliminary Injunction at 8 n.3, 14 n.6, and
25

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 33 of 45

15-17, City of Austin v. Kinder Morgan Texas Pipeline LLC, No. 1:20-CV-138-RP (Doc. 59). Here,
Claims II and III of Sierra Club’s Complaint are based on NEPA, not the ESA, and they involve
broader environmental impacts to surface, groundwater, and drinking water resources, forests, soils,
and vegetation, wildlife and habitat, and aesthetic and cultural resources—more than just harm to
specific endangered species.14
Nonetheless, the Corps’ action does have irreparable impacts on threatened and endangered
species. The Biological Opinion shows the project “may affect” three endangered species and their
habitat with irreparable harm, regardless of whether this rises to the level of “jeopardizing” the
species. This includes construction in and adjacent to warbler habitat; cutting down oak trees,
fencing Houston toad habitat, and translocation of the Tobusch fishhook cactus. BA at 6-9.
Specifically, the “taking” of golden cheeked warblers will occur through the permanent
destruction of 282 acres of warbler breeding habitat and the degradation of an additional 1,352.3
acres of adjacent habitat, including 393 acres in waters of the United States subject to the Corps’
jurisdiction. BiOp, Ex. C at 36-37, 41, 47, 53. This will result in the “reduction” and increased
“fragmentation” of “feeding, breeding, and sheltering resources for the species,” thereby harming
individual species. Id. at 41-42, 53. Moreover, “impairment of essential behavioral patterns are
reasonably certain to occur.” Id. at 53.

14

In NEPA cases like this one, harm to the “species as a whole” is not required to demonstrate
irreparable harm. See Greater Yellowstone Coalition v. Flowers, 321 F.3d 1250, 1258 (10th Cir. 2003) (“By
adopting the ESA standard, requiring that a plaintiff show damage to an entire species, as the
standard for evaluating irreparable harm in a CWA or NEPA challenge, the district court based its
decision on an erroneous conclusion of law. We conclude that, to the extent that the district court
based its denial of a preliminary injunction on the plaintiffs' failure to establish harm to the species
as a whole, this was an abuse of discretion.”). Aransas Project v. Shaw, 775 F.3d 641,663-64 (5th Cir.
2014), does not hold otherwise; instead, the court reversed an injunction because plaintiffs only
showed past harm to whooping cranes with no “likely, imminent replication” of that harm. Here,
the Permian Highway Pipeline is causing—and will continue to cause—irreparable harm to
individual species, permanent destruction of habitat, and irreparable harm to the environment, water
resources, and Sierra Club’s members’ protectable interests.
26

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 34 of 45

Construction of the Permian Highway Pipeline will also potentially result in the fatal take of
eight adult Houston toads, as well as all juvenile Houston toads present in the Corps’ Action Areas.
Id. at 54. Construction will cause “[r]eduction of fitness to individuals by impairing breeding,
feeding, and sheltering caused by loss and degradation of habitat.” Id. The Service found
construction “will … require significant earth moving activities (trenching) with heavy machinery
and other vehicles that have the potential to kill, injure, and otherwise disturb toads . . .” Id. at 39.
All told, the Permian Highway Pipeline construction will destroy 152.6 acres of Houston toad
habitat and adversely impact 1,445.9 acres, 578.9 acres of which are in waters of the United States
subject to the Corps’ oversight. Id. at 37-38. The habitat within this area is not expected to recover
to conditions suitable for Houston toad occupancy. Id. at 38-39, 45.
Construction of pipeline will also include the removal and relocation of 42 Tobusch
fishhook cacti with no guarantee they will survive. Id. at 46. The remaining 62 Tobusch fishhook
cactus “may experience reduced reproductive potential and gene flow.” Id. at 42. Habitat within the
50-foot right-of-way is not anticipated to recover to suitable conditions for the Tobusch fishhook
cactus Id. at 40. Additional individuals may be impacted or crushed during vegetation management
and pipeline maintenance. Id. at 40. Although the Corps and the Permian Highway Pipeline have
plans to “minimize”—but not eliminate—harm to the endangered species, id. at 3, the agency’s
findings on mitigation are not determinative of irreparable harm. See, e.g., Greater Yellowstone Coalition,
321 F.3d 1250, 1259-61 (10th Cir. 2003) (finding irreparable harm from development despite agency
mitigation measures); Sierra Forest Legacy v. Sherman, 646 F.3d 1161, 1185 (9th Cir. 2011).
In sum, the construction of the Permian Highway Pipeline and the implementation of the
terms and conditions of the Biological Opinion will result in, and are already causing, permanent
environmental impacts to property, water resources, wetlands, wildlife, and forests in and around the
Corps’ Action Area, which Sierra Club members and the public use and enjoy. Had the Corps
27

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 35 of 45

conducted a public environmental review of those wide-ranging impacts, as required by NEPA, the
public, environmental experts and engineers, and Sierra Club members would have had the
opportunity to identify additional alternatives, including a “no action” alternative or alternative
pipeline routes, that could have avoided or further mitigated environmental impacts to waters of the
United States. Those irreparable harms to the environment, coupled with the Corps’ deprivation of
Sierra Club’s members’ procedural rights under NEPA, establish irreparable harm. Fund for Animals
v. Norton, 281 F. Supp. 2d at 222.
C. The Permanent and Irreparable Harms to the Environment and the Public’s Right to
Participate in the Corps’ Decision-making Process Outweigh any Temporary Harm that
a Preliminary Injunction Might Cause.
Where, as here, a plaintiff has shown environmental injury is “sufficiently likely,” the
Supreme Court has held, “the balance of harms will usually favor the issuance of an injunction to
protect the environment.” Amoco Prod. Co. v. Vill. of Gambell, 480 U.S. 531, 545 (1987); see also League
of Wilderness Defs./Blue Mountains Biodiversity Project v. Connaughton, 752 F.3d 755, 766 (9th Cir. 2014)
(irreparable environmental injuries outweigh temporary economic harms); Indigenous Envtl. Network v.
State Dep’t, 369 F. Supp. 3d 1045, 1051-52 (D. Mont. 2018) (concluding potential environmental
damage to the public outweighed any energy security and economic benefits provided by Keystone
XL pipeline). Applying that principle here, it is clear that the irreparable harms to the environment,
plaintiffs, and the public’s right to participate in the Corps’ decision-making process, as discussed
supra, outweigh any temporary harm that a preliminary injunction may cause the Corps, or the
owners of the Permian Highway Pipeline.
As discussed, the continued construction of the Permian Highway Pipeline in the Corps’
Action Area will have significant irreparable environmental impacts. Indeed, the construction of the
pipeline has already resulted in the accidental discharge of 36,000 gallons of toxic drilling fluid into
the Blanco River, and the contamination of local drinking water wells. Due to the unique geological
28

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 36 of 45

features of the region, chemical-laden sediment from that spill (and others like it) will persist in the
aquifer system for many months or years, irreparably harming aquatic species and drinking water
resources. Hayes Decl., Ex. B at 9.
Clearing, grading, and trenching for the pipeline right-of-way though waters of the United
States, will also result in sediment discharges that inundate and permanently destroy aquatic species
and their habitat. Moreover, these environmental impacts and the noise, emissions, and visual blight
associated with the pipeline will occur on hundreds of miles of private property, including that of
Plaintiffs’ members.
And as discussed, Plaintiffs and the public will be irreparably harmed by the Corps’ failure to
provide for public participation and comment before issuing the verifications, as required by the
NEPA. This “risk of uninformed decisionmaking regarding … delicate and intertwined natural
resources outweighs any potential harm accruing to Defendants.” San Luis Valley Ecosystem Council v.
U.S. Fish & Wildlife Serv., 657 F. Supp. 2d 1233, 1242 (D. Colo. 2009) (finding harm to applicant not
compelling because a “delay in drilling the exploratory wells is not irreparable…”). The public’s right
to participate in the federal agency decision-making processes weighs decidedly in favor of an
injunction.
These minimum standards for public review and comment were not met because the Corps
arbitrarily failed to disclose material information to the public before issuing its verifications. Indeed,
the Corps provided no public notice of the NWP 12 verifications. As a result, there was no
opportunity for the public to learn of—let alone provide comment on—the individual and
cumulative effects of the Corps’ decision to allow Permian Highway Pipeline to conduct dredge and
fill activities in 129 of the most environmentally sensitive streams and wetlands in central Texas. Nor
was there any opportunity for the public to weigh in on alternatives, including a no action
alternative, or mitigation measures that might avoid or further reduce any impacts. The Corps’
29

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 37 of 45

failure to conduct any environmental or public review is a “serious, immediate, and irreparable
injury.” Heckler, 756 F.2d at 157.
Meanwhile, there would be no injury to the Corps from an injunction, and any injury to the
Permian Highway Pipeline would be purely economic and temporary. As an initial matter, economic
harm is not irreparable and does not provide an adequate basis for denying injunctive relief. See e.g.,
Sampson v. Murray, 415 U.S. 61, 90 (1974) (potential monetary injury is not irreparable). Moreover,
courts have consistently held that the “loss of anticipated revenues . . . does not outweigh irreparable
damage to the environment.” Nat’l Parks Conservation Ass’n v. Babbitt, 241 F.3d 722, 738 (9th Cir.
2001); see also League of Wilderness Defs./Blue Mountains Biodiversity Project v. Connaughton, 752 F.3d at 766
(irreparable environmental injuries outweigh temporary economic harms)
That the project might be delayed if the Corps is required to conduct a NEPA analysis is no
injury to the Permian Highway Pipeline. See Alaska Center for the Environment v. West, 31 F. Supp. 2d
711, 723 (D. Alaska 1998) (noting longer permit processing time was “not of consequence sufficient
to outweigh irreversible harm to the environment”); see Wild Earth Guardians v. Zinke, 368 F. Supp.
3d 41, 84 n.35 (D.D.C. 2019) (citation omitted) (“the risk of economic harm from procedural delay
and industrial inconvenience ‘is the nature of doing business, especially in an area fraught with
bureaucracy and litigation’”). Similarly, the Fifth Circuit has recognized that, where a plaintiff has
demonstrated a clear violation of NEPA, the “remedy should be shaped so as to fulfill the objective
of the statute as closely as possible,” and preliminary injunction is often appropriate to protect the
public interest, even if the project has already commenced. Envtl. Def. Fund v. Marsh, 651 F.2d at
1005 (enjoining a federal highway project where the Corps refused to prepare an adequate NEPA
analysis addressing “significant environmental impacts,” even though the project was “55%
complete”).

30

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 38 of 45

In any event, Sierra Club’s requested injunctive relief would not actually require Permian
Highway Pipeline to cease all construction activities. Instead, Sierra Club’s requests only that the
Court stay the Corps’ of Engineers’ Clean Water Act NWP 12 verifications and enjoin any dredge
and fill or other ground disturbing activities in the discrete 129 water crossing that comprise the
Corps’ Action Area until the agency fully evaluates the direct and cumulative impacts of dredge and
fill activities in those 129 water crossings. The Corps’ Action Area consists of only 2,100 acres of the
approximately 31,000 acres impacted by the project—a mere 7% of the entire project. This limited
injunction would require the Corps to fully evaluate, and invite public comment on, the direct and
cumulative environmental risks and impacts of its decision to incorporate into the Clean Water Act
verifications of the terms and conditions of the Biological Opinion before reauthorizing the PHP to
conduct dredge and fill activities in those discrete Action Areas. Meanwhile, Permian Highway
Pipeline is free to continue construction in the areas outside the Corps’ Action Area.
In any event, any potential harm to the pipeline owners is largely self-inflicted because they
chose to proceed—and continue to engage in dredge and fill activities to this day—knowing that the
Corps failed to conduct the environmental and formal public review process required under NEPA.
See Davis v. Mineta, 302 F.3d 1104, 116 (10th Cir. 2002); see also Swan View Coal. v. Weber, 52 F. Supp.
3d 1160, 1161-62 (D. Mont. 2014) (any alleged harm “resulted from [the agency’s] failure to follow
the law in the first instance”). In fact, numerous Texas municipalities, community organizations,
property owners, and citizens reached out to Permian Highway Pipeline expressing concern about
the Company’s failure to conduct required environmental and public reviews before beginning
construction. Despite having ample notice of the public concerns about the Company’s “effort to
avoid fully analyzing the impacts of their project on the human and natural environmental,
disclosing these impacts to the public or to elected officials, or allowing any sort of public comment
on the environmental effects of their project,” Letter from Lon Shell, Hays County Commissioner,
31

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 39 of 45

to Margaret Everson, U.S. Fish and Wildlife, Ex. M, the pipeline proceeded without ensuring the
Corps had complied with basic requirements of NEPA. The Company cannot now claim that a
preliminary injunction to complete that environmental and public review process would impose
irreparable harm. See, e.g., Long v. Robinson, 432 F.2d 977, 981 (4th Cir. 1970) (finding it “elementary
that a party may not claim equity in his own defaults”); Fund for Animals v. Norton, 294 F. Supp. 2d
92, 116-117 (D.D.C. 2003) (refusing to grant equitable relief where party’s actions were
“disingenuous at best,” and finding that “any economic or emotional harm . . . falls squarely on the
defendants’ shoulders”).
Additionally, “there is no reason to believe that the delay in construction activities caused by
the court's injunction will reduce significantly any future economic benefit that may result from the
[project’s] operation.” See Alaska Conservation Council v. U.S Army Corps of Eng'rs, 472 F.3d 1097, 1101
(9th Cir. 2006), rev'd on other grounds, 129 S. Ct. 2458 (2009). Moreover, any harm to Permian Highway
Pipeline from delaying the project sufficiently to ensure compliance with the law is temporary at
best. Granting limited preliminary injunctive relief here would only serve to preserve the status quo
until the Corps completes the public review process, and evaluates the direct and cumulative
environmental impacts of allowing dredge and fill activities in 129 individual waters of the United
States within the Corps’ Action Area. This modest request, as compared to the alternative—allowing
Permian Highway Pipeline to permanently destroy sensitive habitat and irreparably damage public
drinking water supplies and aquatic resources across some of the most environmentally sensitive
streams and aquifers in central Texas—overrides any arguable harm that the agency could possibly
offer in advocating against such relief.
D. The Public Interest Favors Issuance of a Preliminary Injunction.
The public interest tips in favor of a preliminary injunction staying the Corps’ Clean Water
Act verifications for the Permian Highway Pipeline, and enjoining any further ground disturbance in
32

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 40 of 45

and around the 129 separate stream crossings that comprise the Corps’ Action Areas (see App. A to
Biological Assessment, Ex. A), until the NEPA process is complete, for several reasons.
First, the public has an “undeniable interest” in ensuring that public officials comply with the
law. Colorado Wild v. U.S. Forest Serv., 523 F. Supp. 2d 1213, 1223 (D. Colo. 2007); see also Seattle
Audubon Society v. Evans, 771 F. Supp. 1081, 1096 (W.D. Wash. 1991), aff’d, 952 F.2d 297 (9th Cir.
1991) (“[t]his invokes a public interest of the highest order: the interest in having government
officials act in accordance with the law.”); Mont. Wilderness Ass’n v. Fry, 408 F. Supp. 2d 1032, 1038
(D. Mont. 2006) (The “most basic premise of Congress’ environmental laws” is that “the public
interest is best served when the law is followed.”); Fund for Animals, Inc. v. Espy, 814 F. Supp. 142,
152 (D.D.C. 1993) (the public interest is in “meticulous compliance with the law by public
officials”); Fund for Animals, Inc. v. Norton, 281 F. Supp. 2d at 237 (finding a public interest in
“compliance with NEPA”).
Second, and relatedly, courts have recognized that congressional intent and statute’s
purposes are indicative of the public’s interest. See Mississippi Power & Light Co. v. United Gas Pipe Line
Co., 760 F.2d 618, 624 (5th Cir. 1985) (affirming a preliminary injunction under the Utility Reform
Act, in part, because the Act “announces the strong public interest involved in the determination” of
the legality and fairness of utility rates before passing costs on to consumers). Like the Utility
Reform Act in Mississippi Power, NEPA reflects an unambiguous mandate that federal agencies
“document the potential environmental impacts of significant decisions before they are made, thereby
ensuring that environmental issues are considered by the agency and that important information is
made available to the larger audience that may help to make the decision or will be affected by it.”
Wilderness Watch v. Mainella, 375 F.3d 1085, 1094 (11th Cir. 2004) (emphasis added). To that end,
“Congress has presumptively determined that the failure to comply with NEPA has detrimental
consequences for the environment,” and by extension, the public interest. Davis v. Mineta, 302 F.3d
33

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 41 of 45

at 1116 abrogated on other grounds, Dine Citizens Against Ruining Our Environment v. Jewell, 839 F. 3d 1276
(10th Cir. 2016).
“There is no question that the public has an interest in having Congress’ mandates in NEPA
carried out accurately and completely.” Brady Campaign to Prevent Gun Violence v. Salazar, 612 F. Supp.
2d 1, 26 (D.D.C. 2009) (holding that the public has an interest in ensuring that agency action “does
not give way to unintended environmental consequences that have not (but should have) been
evaluated by Defendants,” and granting a preliminary injunction); see also Fund for Animals, 27 F.
Supp. 2d at 15 (“the public interest expressed by Congress [] was frustrated by the federal
defendants not complying with NEPA. Therefore, the public interest would be served by having the
federal defendants address the public's expressed environmental concerns, as encompassed by
NEPA, by complying with NEPA's requirements.”).
Third, to give meaning and effect to the public’s interest in fully informed decision-making,
as mandated by NEPA, an injunction is warranted “so that the momentum of additional work and
investment does not serve further to bind the agency to its initial decision.” Realty Income Trust v.
Eckerd, 564 F.2d 447, 457 (D.C. Cir. 1977). Although the court cannot turn back time, courts have
recognized that fashioning a remedy that restores that choice as much as possible is necessary and
appropriate. Mont. Wilderness Ass’n v. Fry, 310 F. Supp. 2d 1127, 1156-57 (D. Mont. 2004). An
injunction in this case would give effect to NEPA’s requirement that the Corps conducts a full and
complete analysis before completing the project, and before alternatives, “including the option of taking
‘no action,’” are completely foreclosed. Silverton Snowmobile Club v. U.S. Forest Serv., 433 F.3d 772, 780
(10th Cir. 2006) (quoting 42 U.S.C. § 4332(2)(C)(emphasis added)); see also Pennaco Energy Inc. v. U.S.
Dept. of Interior, 377 F.3d 1147, 1159 (10th Cir. 2004) (“Agencies are required to satisfy the NEPA
‘before committing themselves irretrievably to a given course of action, so that the action can be
shaped to account for environmental values.’”).
34

 Case 1:20-cv-00460-RP Document 10 Filed 06/19/20 Page 42 of 45

Here, the risk of irreparable inundation of sensitive habitat, the documented destruction of
irreplaceable drinking water and aquatic resources, the risk of catastrophic pipeline failure, and the
public interest in ensuring the Corps fully consider the environmental impacts and alternatives to
their actions before authorizing the project all outweigh the temporary economic harm of an
injunction. Accordingly, the public interest tips heavily in favor of staying the Corps’ Clean Water
Act verifications for the Permian Highway Pipeline. See Nat’l Wildlife Fed’n v. Burford, 835 F.2d 305,
326-27 (D.C. Cir. 1987) (affirming district court’s finding that an injunction was in the public interest
to “protect against further illegal action pending resolution of the merits” and to “protect[] the
environment from any threat of permanent damage”); see also Fund For Animals v. Clark, 27 F. Supp.
2d at 15 (granting a preliminary injunction, in part, because the public’s interest would be “served by
having the federal defendants address the public’s expressed environmental concerns, as
encompassed by NEPA.”).15 Finally, the public has a strong interest in “prevent[ing] the judicial
process from being rendered futile by defendant’s action or refusal to act.” Canal Authority of Fla.
State, 489 F.2d at 573 (citing Wright & Miller, Federal Practice and Procedure: Civil § 2947). Where,
as here, a “meaningful decision on the merits would be impossible without an injunction, the district
court may maintain the status quo and issue a preliminary injunction to protect a remedy, including a
damages remedy.” Janey v. Alguire, 647 F.3d 585, 600 (5th Cir. 2011) (quoting Productos Carnic, S.A. v.
Cent. Amer. Beef & Seafood Trading Co., 621 F.2d 683, 686-87 (5th Cir.1980)). As discussed above, the
Permian Highway Pipeline has already begun dredge and fill activities in several of the waters of the

15

Plaintiffs request that the Court waive the bond requirement or impose a nominal bond under the
public interest exception to Fed. R. Civ. P. 65(c). See e.g. Kansas v. Adams, 705 F.2d 1267, 1269 (10th
Cir. 1983); Colo. Wild v. U.S. Forest Serv., 299 F. Supp. 2d 1184, 1191 n.31 (D. Colo. 2004). Courts
have long declined to impose anything more than a minimal bond in order to avoid frustrating
“public-interest” litigation. See California ex rel. Van De Kamp v. Tahoe Reg'l Planning Agency, 766 F.2d
1319, 1325-26 (9th Cir. 1985); Natural Resources Defense Council v. Morton, 337 F. Supp. 167, 168-69
(D.D.C. 1971. Plaintiffs’ likelihood of success should “tip[] in favor of a minimal bond or no bond
at all.” California ex rel. Van De Kamp, 766 F.2d at 1326.

United States within the Corps’ Action Area. Without a preliminary injunction to preserve the status
quo, any remedy could render futile the core purposes of any NEPA review process—thorough
consideration of impacts and alternatives and public participation before the Corps authorizes
completion of the pipeline.
CONCLUSION
For the reasons set forth above, Sierra Club respectfully requests the Court enter a
preliminary injunction on Complaint Claims for Relief II and III, to enjoin the Corps’ verifications
and all actions taken pursuant to them, including any dredge and fill or other ground disturbing
activities in the 129 water crossings that comprise the Corps’ Action Areas.
