INTRODUCTION

AND SUMMARY OF ARGUMENT

This Court granted review to decide whether the

Ninth Circuit set forth the correct test for determining whether adjacent wetlands are “waters of the

United States” that qualify for protection under the

Clean Water Act, 33 U.S.C. § 1362(7) (CWA). Yet petitioners and some of their amici propose answers to

that question that would require the Court to decide

a much broader issue and define the full scope of “waters of the United States” under the CWA.

The Court should decline that invitation. The

CWA’s definition of “waters” is complex, as this Court

is well aware. There is no need in this case to reach

out beyond the question presented, and there are good

reasons to keep the holding limited to the category of

wetlands at issue here: those adjacent to both a traditional navigable water and a jurisdictional non-navigable tributary to a traditional navigable water.

Our nation’s waters form diverse aquatic ecosystems that can’t be reduced to a one-size-fits-all test.

The deepest lake in the United States has been found

not to be a traditional “navigable” water in the sense

urged by petitioners, and it has no known surface or

subsurface connection to any other body of water. One

of the biggest rivers in California regularly goes dry.

About a fifth of New Mexico and a large portion of

Idaho are within “closed basin” aquatic ecosystems of

lakes, rivers, streams, and wetlands that have no direct surface connection to any traditional navigable

waters. Texas’s vast wetlands form critical barriers to

catastrophic flooding that can impact commerce

6

throughout the nation, yet many of these wetlands

have no surface connections to other waters.

All of these waters, and many others, are vital to

both local communities and commerce in the nation

as a whole. Yet they lack surface connections to traditional navigable waters, and thus might not qualify

for CWA protection under the tests proposed by petitioners and their amici. This is why the objective of

the CWA is not protection of traditional navigable waters, but rather protection of the nation’s waters –

that is, the aquatic ecosystems that comprise the “waters of the United States.”

There is no need to decide anything beyond the

wetlands at issue here. While petitioners frame this

case as involving just three key precedents, this Court

has examined the CWA in numerous cases over the

last five decades, and has recognized several categories of waters as falling within the CWA’s jurisdiction.

Those other categories have never been called into

question. This Court should address only the proper

test for adjacent wetlands, and should affirm the

Ninth Circuit’s decision for all the reasons explained

below and in the government’s brief.

ARGUMENT

I.

The CWA’s Broad Objective Can Only Be

Achieved by Protecting All of the Waters

that Make Up Aquatic Ecosystems.

Congress passed the Federal Water Pollution Control Act of 1972, 33 U.S.C. § 1251 et seq., commonly

known as the CWA, to “restore and maintain the

chemical, physical, and biological integrity of the Nation’s waters.” 33 U.S.C. § 1251(a); Cnty. of Maui v.

Haw. Wildlife Fund, 140 S. Ct. 1462, 1468 (2020). The

CWA is not focused on the protection of navigation,

but instead seeks to conserve waters “for the protection and propagation of fish and aquatic life and wildlife, recreational purposes, and the withdrawal of

such waters for public water supply, agricultural, industrial, and other purposes.” 33 U.S.C. § 1252(a).

This Court has long recognized the CWA as “an

all-encompassing program of water pollution regulation” that “applies to all point sources[,] virtually all

bodies of water,” and “virtually all surface water in

the country.” Int’l Paper Co. v. Ouellette, 479 U.S. 481,

486, 492 (1987) (internal quotations omitted); see also,

e.g., S. Rep. No. 92-414, at 95 (1972) (“to establish a

comprehensive long-range policy for the elimination

of water pollution”). Congress intended the CWA to

achieve these objectives by regulating pollution at its

source. Cnty. of Maui, 140 S. Ct. at 1473 (citing EPA

v. Cal. ex rel. State Water Resources Control Bd., 426

U.S. 200, 202-04 (1976)).

The “broad objective” of the CWA requires “[p]rotection of aquatic ecosystems, [which] demand[s]

broad federal authority to control pollution, for

‘[w]ater moves in hydrologic cycles and it is essential

that discharge of pollutants be controlled at the

source.’” United States v. Riverside Bayview Homes,

Inc., 474 U.S. 121, 132-33 (1985) (quoting S. Rep. No.

92-414, at 77). Congress took a “broad, systemic view

of the goal of maintaining and improving water quality.” Id. at 132.

As this Court noted, “‘[w]e cannot, in these circumstances, conclude that Congress has given authority

inadequate to achieve with reasonable effectiveness

8

the purposes for which it has acted.’” E. I. du Pont de

Nemours & Co. v. Train, 430 U.S. 112, 132 (1977)

(quoting In re Permian Basin Area Rate Cases, 390

U.S. 747, 777 (1968)). The CWA broadly protects entire aquatic ecosystems, and this Court should not

limit the Act’s jurisdiction2 in a manner that interferes with that objective.

A.

The structure and text of the CWA

extend jurisdiction to the constitutional limits of Congress’ authority.

In addition to its central objective of restoring and

maintaining the “chemical, physical, and biological

integrity of the Nation’s waters,” the CWA sets a national goal that “discharge of pollutants into the navigable waters be eliminated,” and an interim goal of

improving water quality that “provides for the protection and propagation of fish, shellfish, and wildlife

and provides for recreation in and on the water.” 33

U.S.C. § 1251(a)(1), (2).

The CWA broadly defines “navigable waters” as

“the waters of the United States, including the territorial seas.” 33 U.S.C. § 1362(7); see also Riverside

Bayview, 474 U.S. at 132-33 (“Protection of aquatic

ecosystems, Congress recognized, demanded broad

federal authority to control pollution . . . .”). The

CWA’s “definition of ‘navigable waters’ as ‘the waters

2 The agencies charged with interpreting the CWA and the

cases applying the Act have traditionally discussed the CWA’s

“jurisdiction,” and referred to waters covered by the CWA as “jurisdictional” waters. This brief follows that convention, but references to the CWA’s jurisdiction should not be taken to suggest

limits on the federal courts’ subject-matter jurisdiction. See, e.g.,

Arbaugh v. Y & H Corp., 546 U.S. 500, 510-11 (2006).

9

of the United States’ makes clear that the term ‘navigable’ as used in the Act is of limited import.” Riverside Bayview, 474 U.S. at 133; see also Ouellette, 479

U.S. at 486 n.6. The phrase “waters of the United

States” gives meaning to the phrase “navigable waters” under the CWA—not the other way around.

The Court has, in two recent decisions, recognized

that the CWA’s broad objective must be considered in

interpreting the term “waters of the United States.”

See Cnty. of Maui, 140 S. Ct. at 1476; Nat’l Ass’n of

Mfrs. v. Dep’t of Defense, 138 S. Ct. 617, 624 (2018).

The broad scope of the CWA is apparent in the text of

the Act; the Act’s breadth is vital to achieving the

statute’s objective and goals, as well as to its effectiveness in regulating pollution.

For example, water quality standards are required

to be established under the CWA for both interstate

and intrastate waters “to protect the public health or

welfare, enhance the quality of water and serve the

purposes” of the CWA. 33 U.S.C. § 1313(a), (c)(2)(A).

Each state is required to “identify those waters within

its boundaries” that are polluted and not meeting water quality standards and must take steps to implement the applicable water quality standards. 33

U.S.C. § 1313(d) (emphasis added). The CWA also

grants the U.S. Environmental Protection Agency

(EPA) Administrator authority to investigate “the

condition of any waters in any State or States,” and

“the discharges of any sewage, industrial wastes, or

substance which may adversely affect such waters.”

33 U.S.C. § 1252(a) (emphasis added).

This Court has confirmed the breadth of CWA jurisdiction over “lakes, rivers, streams, and other

10

bodies of water,” including “intrastate waters” and

wetlands adjacent to “other bodies of water.” Riverside Bayview, 474 U.S. at 123, 131-35; see Ouellette,

479 U.S. at 486 n.6; PUD No. 1 of Jefferson Cnty. v.

Wash. Dep’t of Ecology, 511 U.S. 700, 704 (1994) (confirming CWA “requires each State, subject to federal

approval, to institute comprehensive water quality

standards establishing water quality goals for all intrastate waters”) (emphasis added).

The CWA’s coverage of interstate waters is so

broad and comprehensive that it eliminated alternative remedies in interstate pollution cases. See City of

Milwaukee v. Illinois & Michigan, 451 U.S. 304, 33132 (1981) (CWA displaced federal common law); Ouellette, 479 U.S. at 494 (CWA preempted downstream

state’s common law); Arkansas v. Oklahoma, 503 U.S.

91, 98-100 (1992) (a downstream state’s remedy is to

enforce its water quality standard against an upstream state through the CWA’s permitting process).

The CWA therefore changed the mechanism for addressing this interstate pollution from what it had

been for the century preceding the CWA’s passage.

See, e.g., Am. Farm Bureau Fed’n v. EPA, 792 F.3d

281, 304 (3d Cir. 2015).

While, as discussed below, the Court has expressed some limits on the CWA’s broad statement of

jurisdiction, it has only done so in narrow contexts

and has not set out any jurisdictional limitations for

most categories of waters. The text and structure of

the CWA, and case law interpreting it, mandate a

broad understanding of CWA jurisdiction.

11

B.

The legislative history of the CWA

supports a broad reading of CWA jurisdiction that extends to the limits

of the Constitution.

United States statutes have protected navigable

waters and their tributaries since at least 1899,3 and

interstate waters and their tributaries since 1948.4

But Congress’ Commerce Clause authority to control

pollution is not limited to traditional tests of navigability, and Congress did not intend the CWA to be so

limited. See, e.g., Riverside Bayview, 474 U.S. at 13233. Instead, Congress intended to expand the jurisdictional scope of the CWA and to regulate broadly in order to eliminate water pollution and to restore and

protect entire “aquatic ecosystems” by protecting

their component parts as “waters of the United

States.” Id. (citing S. Rep. No. 92-414). Indeed, the

CWA expressly protects water quality in both intrastate and interstate waters, not just in downstream

traditional navigable waters. See 33 U.S.C.

§ 1313(a)(3)(A).

The Conference Report accompanying the CWA

explains that Congress intended that the term “navigable waters” be given “the broadest possible constitutional interpretation.” S. Conf. Rep. No. 92-1236, at

3 See Rivers and Harbors

Appropriation Act of 1899, also

later known as the Refuse Act, 33 U.S.C. § 407 (making it unlawful to discharge refuse “into any navigable water of the

United States, or into any tributary of any navigable water from

which the same shall float or be washed into such navigable water”); see also United States v. Standard Oil Co., 384 U.S. 224,

229-30 (1966).

4 See Water Pollution Control Act, Pub. L. No. 80-845, 62

Stat. 1155 (June 30, 1948); id. §§ 2(a), 2(d)(1), 2(d)(4), (5).

12

144 (1972). The CWA “defines the term ‘navigable waters’ broadly for water quality purposes. It means all

‘the waters of the United States’ in a geographical

sense. It does not mean ‘navigable waters of the

United States’ in the technical sense as we sometimes

see in some laws. . . . [T]his new definition clearly encompasses all water bodies, including main streams

and their tributaries, for water quality purposes.” 118

Cong. Rec. 33756-57 (1972) (emphasis added). And

“[n]o Congressman’s remarks on the [CWA] were complete without reference to the ‘comprehensive’ nature

of the [legislation].” City of Milwaukee, 451 U.S. at

318.

In one of the first decisions interpreting the CWA,

the court explained how Congress has broad authority

to control pollution, noting “water pollution has a serious effect on interstate commerce and . . . Congress

has the power to regulate activities such as dredging

and filling which cause such pollution. . . . Congress

and the courts have become aware of the lethal effect

pollution has on all organisms. Weakening any of the

life support systems bodes disaster for the rest of the

interrelated life forms.” United States v. Holland, 373

F. Supp. 665, 673 (M.D. Fla. 1974).

The EPA and the House Committee on Government Operations agreed with the decision in Holland.

See Letter from Russell Train, EPA Administrator, to

General Gribble (June 19, 1974), in Section 404 of the

Federal Water Pollution Control Act Amendments of

1972: Hearings Before the Senate Comm. on Pub.

Works, 94th Cong., 2d Sess. 349 (1976) (EPA expressing that “the Holland decision provides a necessary

step for the preservation of our limited wetland resources,” and that “the [Holland] court properly

13

interpreted the jurisdiction granted under the [CWA]

and Congressional power to make such a grant.”).

Soon after, the House Committee on Government

Operations concluded that the Corps should adopt the

broader view of the term waters of the United States

taken by the EPA and by the court in Holland. See

H.R. Rep. No. 93-1396, at 23-27 (1974). The Committee urged the Corps to adopt a new definition that

“complies with the congressional mandate that this

term be given the broadest possible constitutional interpretation.” Id. at 27 (internal quotation marks

omitted).

As this Court explained, “[i]n adopting this definition of ‘navigable waters,’ Congress evidently intended to repudiate limits that had been placed on

federal regulation by earlier water pollution control

statutes and to exercise its powers under the Commerce Clause to regulate at least some waters that

would not be deemed ‘navigable’ under the classical

understanding of that term.” Riverside Bayview, 474

U.S. at 133.

Congress did not premise this expansion of jurisdiction on how waters were connected to traditional

navigable or interstate waters. To the contrary, Congress intended to repudiate the traditional navigability tests and limitations on federal authority, and to

instead use the full authority of the federal government under the Commerce Clause to regulate water

pollution in “virtually all surface water in the country.” Ouellette, 479 U.S. at 486; see, e.g., New York v.

United States, 505 U.S. 144, 167 (1992) (citing Hodel

v. Va. Surface Min. & Reclamation Ass’n, Inc., 452

14

U.S. 264, 288 (1981); Arkansas v. Oklahoma, 503 U.S.

at 101).

Even after the CWA was passed in 1972, legislative history confirms Congress’ understanding of an

expansive scope for the CWA. While Congress considered narrowing the scope of the CWA in 1977, congressional “efforts to narrow the definition of ‘waters’

were abandoned,” and Congress “‘retain[ed] the comprehensive jurisdiction over the Nation’s waters exercised in the 1972 Federal Water Pollution Control

Act.’” Riverside Bayview, 474 U.S. at 136-137 (citation

omitted).

As Senator Baker explained, “[c]ontinuation of the

comprehensive coverage of this program is essential

for the protection of the aquatic environment. The

once seemingly separable types of aquatic systems

are, we now know, interrelated and interdependent.

We cannot expect to preserve the remaining qualities

of our water resources without providing appropriate

protection for the entire resource.” 123 Cong. Rec.

26718 (1977).

II.

SWANCC and Rapanos Are Narrow Decisions that Should Not Be Expanded to

Other Types of Waters.

Petitioners and their amici continue to focus primarily on Solid Waste Agency of N. Cook Cnty. v. U.S.

Army Corps of Eng’rs, 531 U.S. 159 (2001) (SWANCC)

and Rapanos v. United States, 547 U.S. 715 (2006).

But these cases provide only narrow holdings that

should not be transposed onto other categories of waters and do not overrule previous Supreme Court

precedent confirming the exceptional breadth of the

CWA. See, e.g., Rapanos, 547 U.S. at 731 (“We need

15

not decide the precise extent to which the qualifiers

‘navigable’ and ‘of the United States’ restrict the coverage of the Act.”) (Scalia, J., plurality opinion). Because the instant dispute over petitioners’ property

can and should be decided under Riverside Bayview

and Rapanos, such expansion is not even at issue

here.

The SWANCC Court held only “that 33 CFR

§ 328.3(a)(3) (1999), as clarified and applied to petitioner’s balefill site pursuant to the ‘Migratory Bird

Rule,’ 51 Fed. Reg. 41217 (1986), exceeds the authority granted to respondents under § 404(a) of the

CWA.” 531 U.S. at 174. The SWANCC decision was

particularly fact specific as to the petitioner’s abandoned sand and gravel pit; it related solely to CWA

Section 404 jurisdiction under the Migratory Bird

Rule and did not address CWA jurisdiction over any

other categories of waters. SWANCC has no application to this case.

Rapanos addressed an analogous jurisdictional issue, and is certainly relevant to CWA jurisdiction over

the wetlands on petitioner’s property, but not in the

way petitioners suggest. Rapanos was narrow; the issue presented was the extent of CWA jurisdiction over

wetlands adjacent to non-navigable tributaries to traditional navigable waters. 547 U.S. at 786-87. The

Court did not limit CWA jurisdiction over any other

category of water and did not overrule any of the Supreme Court precedent confirming the breadth of

CWA jurisdiction over the nation’s waters discussed

above.

The wetland on the Sacketts’ property is jurisdictional under Rapanos for all the reasons explained in

16

respondents’ brief. This is also consistent with the

Court’s holding in Riverside Bayview and the regulatory definition at 33 C.F.R. § 328.3 (2008) based on

the wetlands’ direct adjacency to a jurisdictional tributary to Priest Lake and to Priest Lake itself.5 Because this dispute can be decided under the existing

tests, there is no cause to either overturn EPA’s decision or to lay out a new test that applies to this category of wetlands.

More broadly, though, the issue of what test applies to any other category of “waters” is not, and

need not be, before the Court. The Court should not

endorse attempts by other litigants here to expand

their interpretations of SWANCC and Rapanos to

other waters or to create some new test that sweeps

more broadly than is necessary to resolve the narrow

dispute over petitioners’ wetlands. As discussed below, narrowing CWA jurisdiction as suggested by

these litigants would have serious economic, public

health, and water quality consequences.

III.

Any Test Based Solely on Connections to

Traditional Navigable Waters Would Exclude Iconic and Important Waters of the

United States.

Eliminating federal jurisdiction over certain categories of waters and leaving regulation of those

5 The district court also found that EPA’s alternative basis

for jurisdiction, adjacency, and likely direct subsurface flow into

Priest Lake 300 feet away, was also not arbitrary and capricious

and was also sufficient for CWA jurisdiction purposes. Sackett v.

EPA, No. 2:08-cv-00185-EJL, 2019 WL 13026870, at *9-10 (D.

Idaho Mar. 31, 2019). However, the Ninth Circuit did not rely on

or discuss this alternative jurisdictional basis.

17

categories solely to the states would doom the CWA’s

objective and goals to failure. Congress passed the

CWA because the states had been unable to adequately control water pollution—with burning rivers,

massive fish kills, declining shellfish populations, and

closed beaches capturing public attention.6 These incidents made clear the need for the CWA to protect

national interests. See, e.g., EPA v. Cal. ex rel., 426

U.S. at 202-09; Am. Farm Bureau Fed’n, 792 F.3d at

309.

A jurisdictional test adequate to protect one category of waters will not adequately protect all other

categories of the nation’s waters. The waters of the

United States appear in countless forms with varying

interconnections and functions in aquatic ecosystems.

Pollution or destruction of each type of waters will

present differing types of adverse impacts on interstate commerce.

The EPA and the Corps first promulgated regulations defining waters of the United States in the mid1970s. See, e.g., 40 C.F.R. § 122.2 (2015); 33 C.F.R.

§ 328.3 (2015) (1970s Regulatory Definition). That

definition is currently in effect and was the definition

when the EPA made the jurisdictional determination

for the wetland on petitioners’ property. It asserts jurisdiction over traditionally navigable waters, interstate waters, tributaries to those (and other) jurisdictional waters, wetlands adjacent to other

18

jurisdictional waters, and any “other waters,” the use,

degradation, or destruction of which could affect interstate or foreign commerce. See, e.g., 40 C.F.R.

§ 122.2 (2015); 33 C.F.R. § 328.3 (2015). The 1970s

Regulatory Definition has not been overturned by this

Court’s numerous cases addressing CWA jurisdiction

through application of the definition. See, e.g., Riverside Bayview, 474 U.S. at 131, 135.

Rather than attempt a single rule that addresses

jurisdiction over all categories of waters based on, for

example, their surface connection to other jurisdictional waters or significant nexus to traditional navigable waters, the 1970s Regulatory Definition appropriately recognizes that there are numerous distinct

categories of waters that are jurisdictional for distinct

reasons.

As explained below, many vital waters of national

importance could suddenly become non-jurisdictional

and lose their long-standing CWA protections under

the tests proposed by petitioners and their amici

here.7 Such a result would be contrary to the CWA

and preclude achievement of the Act’s objective.

7 For example, petitioners assert that the CWA only protects

narrowly defined interstate traditionally navigable waters and

intrastate navigable waters “forming segments of an interstate

channel of commerce.” See Petr’s. Br. 22-24, 43-44. Under this

unfounded theory, only wetlands with a “continuous surface-water connection” to this narrow class of waters can be protected by

the CWA. Id.

Crater Lake

Crater Lake National Park, Oregon8

To see the difficulty in basing a CWA test on traditional notions of navigability, the Court need look

no further than Crater Lake, the deepest lake in the

United States and one of the clearest and cleanest

lakes in the world.9

The lake rests in a collapsed volcano at the heart

of Crater Lake National Park. More than half a million people visit it each year, fishing, swimming, and

spending tourist dollars around the lake.10

Yet Crater Lake would fail many of the tests proffered in this case. It is fed by snowmelt and rainfall,

and countless other lakes might lose CWA protection.

Any definition of “waters” that depends on traditional notions of navigability, or that is based on erroneous assumptions about how all waters flow to the

sea, will exclude waters of significant national importance from federal protection.

New Mexico’s Closed Basins

These closed basins are home to portions of two

National Wilderness Areas that contain CWA designated Outstanding National Resource Waters.19 New

Mexico’s closed basins also intersect federal lands and

many areas of national importance, such as the White

Sands National Park, Lake Holloman, Organ Mountains Desert Peaks National Monument, and several

national forests.20

The closed basins contain diverse waters, including 84 miles of perennial streams, 3,900 miles of intermittent waters, and 4,000 playa wetlands.21 These

These basins are important aquatic ecosystems

and provide vital resources to communities and tribes

who rely on drinking water from the closed basins’

many other links to interstate and foreign commerce,

including irrigating crops sold in interstate and foreign commerce, providing mineral resources dependent on good water quality (such as salt), and creating

recreational and other opportunities for interstate

and foreign travelers.24

Waters within these closed basins are subject to

pollutant discharges from many sources, including

the Freeport-McMoRan (formerly Phelps Dodge)

Santa Rita copper mine, federal facilities, and municipal wastewater treatment plants.25 The loss of CWA

protections would be particularly devastating in New

Mexico because it is one of just three states that lack

This closed basin includes the drainages of five watersheds that play an important economic and ecological role already being harmed by pollution.30 There

are 1,029 named rivers and streams, as well as countless lakes, reservoirs, and wetlands31 that provide valuable aquatic resources in the closed basins. For example, the Big Lost River and Medicine Lodge Creek

provide habitat for rainbow trout, brook trout, and

cutthroat trout, and Little Lost Creek includes critical

habitat for bull trout, listed as threatened under the

federal Endangered Species Act.32

Rivers and streams that flow on the surface in this

closed basin eventually percolate into the volcanic

Snake River Plain Aquifer, then emerge and flow into

the Snake River.33 The EPA has determined that portions of the Big Lost River and Mud Lake within the

closed basin are jurisdictional based on navigability.34

Yet many others are jurisdictional based on the “other

waters” category because their degradation could

harm interstate or foreign commerce (cropland irrigation and recreational fisheries that attract anglers

from throughout the United States).35 Several CWA

Section 402 permits currently control pollution discharges into the closed basin and many streams

within the closed basin are listed on Idaho’s CWA Section 303(d) List of Impaired Waters.36

If the CWA were misinterpreted to only protect

waters with surface connections to traditional navigable waters, it could eliminate CWA protections for waters considered non-navigable, including the Little

Lost River and much of the Big Lost River.37 This loss

of protections would leave these, and other, rivers

subject to water pollution not subject to any federal

minimum standards and would thus harm the uses

The roughly 4,000 square-mile Lower Galveston

Bay watershed, encompassing the greater Houston,

Texas region, is an ecologically diverse area with

abundant water in the form of rivers, creeks, bayous,

coastal marshes, estuaries, wetlands, bays, and the

Gulf of Mexico.

The freshwater wetlands in this ecosystem “are a

bayous and bays.”38 Texas coastal prairie wetlands

were formed thousands of years ago by ancient rivers

and bayous and are found along the Gulf of Mexico

from western Louisiana to south Texas.39 These wetlands are “the headwaters for virtually all of the water bodies feeding into Galveston Bay”40 and serve a

range of important, valuable functions.41

These wetlands provide numerous benefits, but

most notably they prevent flooding by absorbing

storm water and buffering against surges.42 The

greater Houston region has repeatedly experienced

floods and storm surges, including 2017’s Hurricane

Harvey that caused more than 100 deaths and $125

billion in damage.43 The region’s long-term resilience

to major storms depends in large part on the protection of existing freshwater wetlands.

Freshwater wetlands are also critical for filtering

polluted surface water before it makes its way into

Houston’s drinking water supplies and Galveston

Bay, which provides places for paddling, fishing, and

birdwatching and creates billions of dollars of benefits

for the region’s communities.44

For example, much of the surface runoff entering

Galveston Bay first passes through Texas coastal

prairie wetlands, which reduce incoming inorganic nitrogen pollution by around 98% and inorganic phosphorus pollution by 92%45 and are essential to avoiding nutrient pollution and toxic algal blooms that

plague other waters across the country.46

Many of these wetlands do not directly abut, nor

do they have continuous surface connections to, another jurisdictional water, and so they would not qualify as “waters of the United States” under the test proposed by petitioners and some of their amici. Yet scientific research demonstrates that these “geographically isolated” waters are not hydrologically isolated,

but have extensive, regular hydrological connectivity

with nearby jurisdictional waters that account for a

“substantial percentage of the water budget” for the

receiving water.47 These wetlands have significant effects on downstream jurisdictional waters, including

Galveston Bay.48

Ensuring that Texas freshwater wetlands are protected by the CWA is especially important to the protection of the Lower Galveston Bay watershed because Texas does not have any laws in place to prevent or mitigate harm from wetland development.

This has already caused the loss of as much as 29% of

natural freshwater wetlands in some areas over an

18-year period.49

The two largest rivers in California, the Sacramento and the San Joaquin, drain 40% of the state via

the San Francisco Bay-Delta, where these fresh waters meet the Pacific Ocean.53 The resulting ecosystems provide a home for species that exist nowhere

else in the world, as well as a diverse array of fish and

wildlife, see Cal. Wat. Code § 85002, and are used for

recreation, fishing, and religious practices. These

lands also provide drinking water for over 25 million

Californians and irrigation water for hundreds of

thousands of acres of farmland.54

Because of California’s limited wet season, half of

the rivers, creeks, and streams are intermittent and

so do not run year round, and another third are

ephemeral, lacking connection to groundwater and

only flowing during or after precipitation.55 Nearly

85% of the streambeds that surround the San Francisco Bay and Delta lack year-round water.56 And that

figure is increasing with climate change.

More broadly, between two-thirds and 95% of the

streams in the Southwestern U.S. do not contain visible flows year-round.57 And in California, even the

second biggest river in the state, and a host of other

rivers, often are dry during the State’s dry season. See

Figure 9, supra (photo of San Joaquin River).

Requiring consistent visible flows or connections

to traditional navigable waters for CWA jurisdiction

could remove protection for most of these waters and

their interconnected wetlands. Such requirements

could cause waters to fall in and out of jurisdiction depending on whether there was flow when the application or decision was made, leading to unpredictable

jurisdictional determinations that leave downstream

waters unprotected.

These streams and their associated wetlands are

vital to downstream waters and ecosystems, providing the same functions as perennial waters: moving

water, nutrients, and soil. The CWA’s objective and

goals cannot be achieved in the San Francisco Bay,

the Delta, or its watershed without protecting these

States remain insufficiently equipped to control

water pollution in the absence of the CWA’s authorities, standards, and resources. When the EPA sought

to slash its CWA jurisdiction in 2020, see 85 Fed. Reg.

22250 (April 21, 2020), new development projects

caused a sharp increase in unregulated discharges to

waters.58 While this jurisdictional rule was temporarily in place, these projects “proceeded in newly nonjurisdictional waters in states and on tribal lands that

do not and sometimes cannot, regulate waters beyond

those covered by the” CWA.59 Indeed, some states

weakened their regulations governing clean water,

Army on Review of U.S. Army Corps of Eng’rs ORM2 Permit and

(“The Corps’ ORM2 database contains AJDs that evaluated

40,211 individual aquatic resources or water features under the

non-jurisdictional by the Corps. . . . The agencies are aware that

projects are proceeding in newly non-jurisdictional waters in

states and tribal lands where regulation of waters beyond those

covered by the CWA are not authorized, and, based on available

information, will therefore result in discharges without any regulation or mitigation from federal or state agencies.”).

starting a race to the bottom that the CWA was designed to avoid.60 The resultant harm to waters across

the nation undercuts arguments that the states will

step in and fill the regulatory gap if federal CWA jurisdiction over certain waters is eliminated.

Any reduction in CWA jurisdiction will have real

and immediate consequences on the nation’s waters

and will preclude achievement of the CWA’s water

quality and aquatic ecosystem protection objective

and goals. While the CWA has been effective in controlling pollution in many respects, significant pollution persists and is even increasing in many of the nation’s waters. The EPA’s most recent national summary data shows water pollution continues to impair

at least 588,173 miles of rivers and streams;

13,208,917 acres of lakes, ponds, and reservoirs;

44,625 square miles of bays and estuaries; 3,329 miles

of coastal shoreline; and 672,924 acres of wetlands.61

Limitation of CWA jurisdiction will exacerbate these

problems and, as discussed above, leave many nationally important and iconic waters without protection

against pollution and destruction.

CONCLUSION

For the reasons stated above, amici respectfully

ask this Court to affirm the Ninth Circuit’s decision.
