MEMORANDUM OPINION
(March 19, 2009)

Approximately 25 years ago, the Department of the Interior implemented regulations that

generally prohibited possession of firearms in national parks unless they were “packed, cased or

stored in a manner that [would] prevent their ready use.” 48 Fed. Reg. 30,252 (June 30, 1983),

codified at 36 C.F.R. § 2.4(a)(2). A similar regulation applied to firearms in national wildlife

refuges. See 49 Fed. Reg. 18,444 (April 30, 1984), codified at 50 C.F.R. § 27.42(e). These

firearm restrictions are no longer in place. On December 10, 2008, the Department of the
Interior promulgated a final rule that allows persons to possess concealed, loaded, and operable

firearms in national parks and wildlife refuges in accordance with the laws of the state in which

the national park or wildlife refuge is located:

a person may possess, carry, and transport concealed, loaded, and operable
firearms within a [national park or national wildlife refuge] in accordance with the
laws of the state in which the [national park or national wildlife refuge], or that
portion thereof, is located, except as otherwise prohibited by applicable Federal
law.

73 Fed. Reg. 74,966, 74,972 (Dec. 10, 2008), amending 36 C.F.R. § 2.4, 50 C.F.R. § 27.42

(hereinafter, the “Final Rule”). Prior to issuing the Final Rule, the Department of the Interior did

not prepare an environmental assessment or an environmental impact statement pursuant to the

National Environmental Protection Act (“NEPA”), 42 U.S.C. § 4331, et seq.

Plaintiffs Brady Campaign to Prevent Gun Violence (“Brady”) and National Parks

Conservation Association (along with two other Plaintiff organizations, “NPCA”),1 have brought

suit against Secretary Kenneth Salazar, in his official capacity as Secretary of the United States

Department of the Interior (“DOI”), and numerous other governmental entities and officials

(collectively, “Defendants”).2 Plaintiffs assert, inter alia, that Defendants failed to consider the

Final Rule’s environmental impacts in violation of NEPA and multiple other Congressional

1
The other two Plaintiff organizations are the Coalition of National Park Service Retirees
and the Association of National Park Rangers.
2
Pursuant to Federal Rule of Civil Procedure 25(d), the Court has automatically
substituted Kenneth Salazar as the successor to the originally-named lead Defendant, Dirk
Kempthorne. The other named Defendants are the United States Department of the Interior, the
National Park Service, the United States Fish and Wildlife Service, Mary A. Bomar, in her
official capacity as Director of the National Park Service, H. Dale Hall, in his official capacity as
Director of the Fish and Wildlife Service, and R. Lyle Laverty, in his official capacity as
Assistant Secretary of the Interior for Fish, Wildlife and Parks.

statutes.3

The lynchpin of Defendants’ response is that the Final Rule has no environmental

impacts–and that Defendants were not required to perform any environmental analysis–because

the Final Rule only authorizes persons to possess concealed, loaded, and operable firearms in

national parks and wildlife refuges, and does not authorize persons to discharge, brandish, or

otherwise use the concealed, loaded, and operable firearms. In other words, the Final Rule has

no environmental impacts according to Defendants because the Final Rule does not authorize any

environmental impacts. By relying on this tautology, Defendants (1) abdicated their

Congressionally-mandated obligation to evaluate all reasonably foreseeable environmental

impacts, whether authorized by the Final Rule or not, and (2) ignored (without sufficient

explanation) substantial information in the administrative record concerning environmental

impacts, including (i) Defendants’ own long-standing belief under the previous regulations that

allowing only inoperable and stored firearms in national parks and wildlife refuges was necessary

to safeguard against certain risks to the environment and (ii) the almost universal view among

interested parties that persons who possess concealed, loaded, and operable firearms in national

parks and wildlife refuges will use them for any number of reasons, including self-defense

against persons and animals (all of which suggests that the Final Rule will have some impact on

the environment).

3
The Complaint filed by Brady and the Amended Complaint filed by NPCA collectively
assert claims under the Administrative Procedure Act, 5 U.S.C. § 701 et seq., the National
Environmental Protection Act, 42 U.S.C. § 4331 et seq., the Organic Act, 16 U.S.C. § 1 et seq.,
the National Wildlife Refuge System Administration Act, 16 U.S.C. § 668dd, et seq., the
National Historic Preservation Act, 16 U.S.C. § 470 et seq., the Endangered Species Act, 16
U.S.C. § 1531, et seq., and the Declaratory Judgment Act, 28 U.S.C. §§ 2201 and 2202.

3
 Currently pending before the Court is Plaintiffs’ Motion for a Preliminary Injunction to

enjoin implementation of the Final Rule. Because the Court finds that the Final Rule is the

product of Defendants’ astoundingly flawed process, the Court holds that Plaintiffs are highly

likely to prevail on the merits of their NEPA claims.4 The Court also holds that Plaintiffs have

met their burden to show a likelihood of irreparable harm, the absence of significant harm to

other interested persons or entities, and that the public interest weighs in favor of preliminary

injunctive relief. Having balanced all of these considerations and found that they weigh in favor

of issuing a preliminary injunction, the Court shall GRANT Plaintiffs’ Motion for a Preliminary

Injunction.

In reaching this decision, the Court emphasizes that, despite many of the arguments raised

by the parties, intervenor-movants, and amici curiae, this case is not a platform for resolving

disputes concerning the merits of concealed weapons or laws related to concealed weapons that

are appropriately directed to the other branches of government. The Court is bound to consider

only whether Defendants have complied with Congress’ statutes and regulations, and not whether

Defendants have made wise judgments in any normative sense. Accordingly, the Court expresses

no view as to the merits of any laws or regulations related to concealed weapons or firearms

generally.

I. BACKGROUND

A. Factual Background

As explained above, previous regulations pertaining to national parks and wildlife refuges

4
As the Court finds that success on Plaintiffs’ NEPA claims is highly likely, the Court
declines to reach Plaintiffs’ other claims for purposes of their Motion for a Preliminary
Injunction.

4
generally prohibited possession of firearms unless they were unloaded and packed, cased, or

stored in a manner that prevented their ready use. 48 Fed. Reg. 30,252 (June 30, 1983); 49 Fed.

Reg. 18,444 (April 30, 1984). These regulations were “designed to ensure public safety and

provide maximum protection of natural resources by limiting the opportunity for unauthorized

use of weapons . . . while providing reasonable regulatory relief for persons living within or

traveling through park areas.” 48 Fed. Reg. at 30,265.5 As reflected in the Administrative

Record, this view persisted among Defendants until recently. See, e.g., A.R. 339 (11/29/06

National Park Service Briefing Statement) (repeating the justification for firearm restrictions in

national parks and adding that “[m]ost weapons carried for the protection from wildlife are not

adequate for that purpose. Untrained individuals attempting to protect themselves from

dangerous animals often exacerbate the situation”).

Defendants’ views changed. On December 14, 2007, forty-seven United States Senators

wrote to the Secretary of the Interior asking to have these restrictions lifted. 73 Fed. Reg. 74,966,

74,967 (Dec. 10, 2008). Four additional United States Senators made a similar request on

February 11, 2008. Id.6 The DOI “chose to address this issue” on April 30, 2008, by proposing a

new rule to allow persons to possess concealed, loaded, and operable firearms in national parks

and wildlife refuges to the extent permitted in any state park or wildlife refuge in the state in

5
Plaintiffs note, and Defendants do not dispute, that there were also various other types
of firearm restrictions in place prior to implementation of these regulations, including a
restriction on firearm possession in Yosemite National Park dating back to 1897. See Pls.’ Mot.
at 4.
6
Although omitted in the Final Rule, it appears that United States Senators Dianne
Feinstein and Daniel K. Akaka joined with two members of the United States House of
Representatives, Norman D. Dicks and Raul M. Grijalva, to submit a letter during the comment
period opposing any change to the existing regulations. See A.R. 11 (Draft Final Rule).

which the federal park or wildlife refuge was located:

an individual will be able to possess, carry, and transport concealed, loaded, and
operable firearms within a [national park or wildlife refuge] in the same manner,
and to the same extent, that a person may lawfully possess, carry, and transport
concealed, loaded and operable firearms in any [state park or state wildlife refuge]
in the state in which the [national park or wildlife refuge], or that portion thereof,
is located.

73 Fed. Reg. 23,388 (Apr. 30, 2008). The DOI explained that the purpose of this proposed rule

was to better respect the rights of states, forty-eight of which “provide for the possession of

concealed firearms by their citizens,” a larger number than when the previous regulations were

promulgated. Id. Accordingly, the DOI explained that the regulations “should be amended to

defer to this development in State law.” Id. at 23,389.

Conspicuous by its absence, however, was any indication that the previously-recognized

“public safety” and “protection of natural resources” concerns had been alleviated over time. Id.

Instead, the DOI simply acknowledged “its obligations under NEPA to assess the impact of any

Federal action significantly affecting the quality of the human environment, health, and safety,”

and noted that it was “currently working to determine the appropriate level of NEPA assessment

and documentation that will be required for promulgation of this regulation.” Id. at 23,390.

The proposed rule requested public comments until June 30, 2008, a date that was later

extended by an additional thirty days. 73 Fed. Reg. at 74,967. In total, the DOI received

approximately 125,000 public comments on the proposed rule. Id. Significantly–and as

described in greater detail below–many of the comments suggested that allowing persons to

possess concealed, loaded, and operative firearms in national parks and wildlife refuges would

result in the use of those firearms, particularly for self-defense. See, e.g., A.R. 1927 (“I [] go

6
back packing and would like to be able to carr[ry] my fire arm [sic] with me for possible wild

animal attack”); A.R. 5609 (“for those of us who have conceal[ed] carry permits, we carry

[firearms] for the protection of our families and self from those who would do us harm. We are

not looking to shoot anyone unless we are forced to in order to protect our family”). The DOI

formed a working group to analyze these comments and to provide responses in the Final Rule.

73 Fed. Reg. at 74,968-74,970.

On December 10, 2008, the DOI published the Final Rule, making one significant

modification from the proposed rule. Whereas the proposed rule permitted persons to possess

concealed, loaded, and operative firearms if permitted in any state park or wildlife refuge in

which the federal park or wildlife refuge was located, the Final Rule authorizes persons to

possess concealed, loaded, and operative firearms if permitted in accordance with state law

generally:

a person may possess, carry, and transport concealed, loaded, and operable
firearms within a [national park or national wildlife refuge] in accordance with the
laws of the state in which the [national park or national wildlife refuge], or that
portion thereof, is located, except as otherwise prohibited by applicable Federal
law.

73 Fed. Reg. at 74,971. The DOI made this change because “the reference to ‘similar state lands’

in the proposed rule was ambiguous and led to confusion as to what rules would apply to

particular Federal park areas and national wildlife refuges.” Id. at 74,969.

In terms of its obligations under NEPA, the DOI explained that the Final Rule did not

raise any environmental concerns that required evaluation:

The [DOI] has analyzed the [Final Rule] under NEPA and determined that the
action is subject to a categorical exclusion under applicable regulations. First, the
[Final Rule] is in the nature of a legal change to existing rules that will not have

7
 any actual effects on the environment. And second, the [DOI] has determined that
no ‘extraordinary circumstances’ exist which would prevent the proposed action
from being classified as categorically excluded. This decision is fully described in
[the DOI’s] decision document dated November 18, 2008 . . . .

Id. at 74,971. The DOI’s Decision Memorandum, in turn, reflects the DOI’s tautological

reasoning that the Final Rule will have no environmental impacts because it does not authorize

any environmental impacts:

the [DOI] has concluded that the final rule will not have any actual effects on the
environment . . . the amendment does not allow visitors to fire or discharge the
firearms in any way, brandish the weapon in the view of others, or use the firearm
in any other way. In this regard, the [Final Rule] does not authorize any actual
impacts on the environment, and thus meets the test for a categorical exclusion
under relevant regulations and judicial precedent.

A.R. 200 (11/18/08 Decision Memorandum) (emphasis in original).7 The Final Rule became

effective on January 9, 2009. See 73 Fed. Reg. at 74,966.

B. Procedural Background

Brady filed a lawsuit on December 30, 2008. NPCA filed a separate lawsuit on January

6, 2009, along with a Motion for a Preliminary Injunction. See NPCA v. Salazar, Civ. A. No. 09-

013, Docket No. [4]. Brady then filed its own Motion for a Preliminary Injunction on January 9,

2009, incorporating by reference NPCA’s memorandum of law and facts. See Brady v. Salazar,

Civ. A. No. 08-2234, Docket No. [5]. Because both motions rely on the same underlying

memorandum of law and facts, the Court shall refer throughout this Memorandum Opinion to

“Plaintiffs’ Motion for a Preliminary Injunction.”

The Court held a conference call on January 8, 2009, with counsel representing all

7
For purposes of clarity and ease of reference, the Court shall cite directly to the DOI’s
Decision Memorandum throughout this Memorandum Opinion as “Defs.’ Decision Mem.,”
rather than using citations to the Administrative Record.

8
Plaintiffs and Defendants to discuss a briefing schedule for Plaintiffs’ Motion for a Preliminary

Injunction. All parties agreed that “they would suffer no prejudice by extending the briefing on

the preliminary injunction motion beyond the schedule provided by Local Civil Rule 65.1,” and

the Court “also [found] that no prejudice would result.” Min. Order dated Jan. 9, 2009. After a

discussion on the record, the Court agreed to adopt the schedule proposed by the parties that

allowed Defendants to respond to Plaintiffs’ Motion for a Preliminary Injunction by January 30,

2009, and would result in the full briefing of the motion no later than February 13, 2009.

On January 20, 2009, (i.e. after the conference call with the Court but before the date by

which Defendants were to respond to Plaintiffs’ Motion for a Preliminary Injunction), President

Barack Obama took office. Defendants moved for a two-week extension of the briefing schedule

“to provide the new administration that took office . . . an opportunity to consider the issues

raised by Plaintiffs’ motions.” See Unopposed Mot. for Extension at 2 (Jan. 27, 2009). The

Court granted the motion to extend the schedule, allowing Defendants until February 13, 2009, to

file a response to Plaintiffs’ Motion for a Preliminary Injunction, and resulting in the full briefing

of the motion no later than February 27, 2009.

Pursuant to the amended schedule set by the Court, Defendants submitted the complete

administrative record on February 5, 2009, and submitted an Opposition to Plaintiffs’ Motion for

a Preliminary Injunction on February 13, 2009 (“Defs.’ Opp’n”). Brady and NPCA filed separate

Replies in support of the Motion for a Preliminary Injunction on February 23, 2009 (“Brady

Reply” and “NPCA Reply,” respectively). Pursuant to the amended schedule set by the Court,

Defendants filed a consolidated Sur-Reply on February 27, 2009 (“Defs.’ Sur-Reply”).

The Court also received motions from two organizations seeking to intervene as

9
Defendants. The Mountain States Legal Foundation (“MSLF”) filed a Motion to Intervene as a

Defendant in both cases on January 23, 2009. The National Rifle Association (“NRA”) filed a

Motion to Intervene as a Defendant in both cases on January 28, 2009, and February 25, 2009,

respectively. During the pendency of the motions, both the MSLF and the NRA filed

Oppositions to Plaintiffs’ Motion for a Preliminary Injunction. Defendants took no position with

respect to the Motions to Intervene, and Plaintiffs in both cases opposed intervention. For

reasons the Court shall articulate by separate Order, the Court has allowed both the MSLF and

the NRA to intervene as of right as Defendants in the above-captioned cases.8 Accordingly, the

Court has considered the Oppositions to Plaintiffs’ Motion for a Preliminary Injunction filed by

the MSLF and the NRA.

The Court also received motions from several organizations seeking to participate as

amici curiae. The Friends of Acadia and Maine Citizens Against Handgun Violence (collectively,

“FOA”) filed an Unopposed Motion for Leave to Participate as Amicus Curiae in both cases on

February 6, 2009. Safari Club International (“SCI”) also filed an Unopposed Motion for Leave

to Participate as Amicus Curiae in both cases on February 17, 2009. The Court granted both

motions. Accordingly, the Court has reviewed FOA and SCI’s amici briefs for purposes of

ruling on Plaintiffs’ Motion for a Preliminary Injunction.

Finally, each of the parties has moved to submit extra-record evidence in support of

8
As the Court’s separate Order shall indicate, the MSLF and the NRA may intervene
subject to limitations prohibiting them from raising claims outside the scope of those raised by
the original parties or from raising collateral issues. See Fund for Animals, Inc. v. Norton, 322
F.3d 728, 738 n.11 (D.C. Cir. 2003) (describing with approval a district court’s use of restrictions
on intervenors to facilitate the efficient resolution of the proceedings and to prevent undue delay
or prejudice).

10
various arguments. Brady filed a partially opposed motion to submit various declarations “in

support of its position that it has standing and will suffer irreparable harm from Defendants’

actions,” which the Court granted by Minute Order dated March 4, 2009. Similarly, NPCA filed

a partially opposed motion to submit a supplemental declaration, which the Court granted-in-part

and denied-in-part by Minute Order dated March 19, 2009. Finally, Defendants filed a Motion to

submit an “extra-record document” that “evidences Federal Defendants’ interpretation of the

regulations at issue.” See Defs.’ Mot. to Submit Doc. at 2. Even though the Court finds that

consideration of this document is unnecessary to resolve the issues associated with Plaintiffs’

Motion for a Preliminary Injunction, Plaintiffs did not oppose its submission and the Court

granted the motion by Minute Order dated March 19, 2009.

Based on the foregoing, Plaintiffs’ Motion for a Preliminary Injunction is fully briefed

and ripe for decision.

II. LEGAL STANDARDS

A. Preliminary Injunctions

To obtain preliminary injunctive relief, a moving party must show: (1) a substantial

likelihood of success on the merits, (2) that it would suffer irreparable injury if the injunction

were not granted, (3) that an injunction would not substantially injure other interested parties,

and (4) that the public interest would be furthered by the injunction. Chaplaincy of Full Gospel

Churches v. England, 454 F.3d 290, 297 (D.C. Cir. 2006). In applying this four-factored

standard, district courts may employ a sliding scale under which a particularly strong showing in

one area can compensate for weakness in another. Id. Accordingly, “[i]f the showing in one area

is particularly strong, an injunction may issue even if the showings in other areas are rather

11
weak.” Id. (quoting CityFed Fin. Corp. v. Office of Thrift Supervision, 58 F.3d 738, 747 (D.C.

Cir. 1995)). Nevertheless, the D.C. Circuit has advised that a movant must demonstrate “‘at least

some injury’ for a preliminary injunction to issue . . . [because] ‘the basis of injunctive relief in

federal courts has always been irreparable harm . . . .’” Id. (quoting CityFed, 58 F.3d at 747;

Sampson v. Murray, 415 U.S. 61, 88 (1974)).

Defendants raise an argument (albeit in a footnote) that this standard for a preliminary

injunction has been circumscribed by the Supreme Court’s decision in Winter v. Natural. Res.

Def. Council, Inc., __ U.S. __ , 129 S. Ct. 365 (2008). See Defs.’ Opp’n at 11 n.8. See also

MSLF Opp’n at 3 (discussing the application of Winter). The Court disagrees. In Winter, the

Supreme Court held that the Court of Appeals for the Ninth Circuit had applied an erroneous

legal standard by affirming a district court’s preliminary injunction when the plaintiff had only

shown a “possibility” of irreparable harm and where the district court had made almost no

attempt to analyze the balance of equities and the public interest. See 129 S. Ct. at 375, 378.

The Supreme Court found that this standard was too “lenient,” and reaffirmed that a preliminary

injunction should issue only when “irreparable injury is likely in the absence of an injunction.”

Id. (emphasis in original). The Court had no occasion to examine the D.C. Circuit’s precedents

allowing a plaintiff’s strong showing in one area to compensate for weakness in another. Id. at

392 (Ginsburg, J., Dissenting) (“courts have evaluated claims for equitable relief on a ‘sliding

scale,’ sometimes awarding relief based on a lower likelihood of harm when the likelihood of

success is very high . . . This Court has never rejected that formulation, and I do not believe it

does so today.”). In any event, because the D.C. Circuit’s precedents require a plaintiff to show

that “it would suffer irreparable injury if the injunction were not granted,” Chaplaincy, 454 F.3d

12
at 297, the Court finds that the D.C. Circuit’s sliding-scale standard remains viable even in light

of the decision in Winter.9

B. Administrative Procedure Act

Although the Court has discussed Plaintiffs’ claims in the context of NEPA, that statute

does not provide a private right of action. See Karst Envtl. Educ. & Prot., Inc. v. Envtl. Prot.

Agency, 475 F.3d 1291, 1295 (D.C. Cir. 2007). Accordingly, Plaintiffs assert their NEPA claims

under the Administrative Procedure Act (“APA”), 5 U.S.C. § 701 et seq.

Under the APA, the Court sets aside an agency action that is “arbitrary and capricious, an

abuse of discretion, or otherwise not in accordance with the law.” 5 U.S.C. § 706. Compliance

with NEPA, as well as its procedures related to environmental evaluations, are properly analyzed

under the “arbitrary and capricious standard.” Nat’l Trust for Historic Pres. in the U.S. v. Dole,

828 F.2d 776, 781 (D.C. Cir. 1987). The scope of review under this standard is well-established:

the agency must examine the relevant data and articulate a satisfactory
explanation for its action including a rational connection between the facts found
and the choice made. In reviewing that explanation, [the court] must consider
whether the decision was based on a consideration of the relevant factors and
whether there has been a clear error of judgment . . . Normally, an agency rule
would be arbitrary and capricious if the agency has relied on facts which Congress

9
Intervenor-Defendant NRA argues that “[t]he purpose of a preliminary injunction is
merely to preserve the relative positions of the parties until a trial on the merits can be held,”
NRA Opp’n at 2 (quoting Chaplaincy, 454 F.3d at 297), and that the Final Rule became effective
on January 9, 2009. It is unclear what the NRA hopes to achieve with this argument. Plaintiffs
filed their initial Motion for a Preliminary Injunction on January 6, 2009, prior to the effective
date of the Final Rule. During the conference call with the Court on January 8, 2009, all parties
agreed to an extended briefing schedule to allow a more fulsome briefing on the relevant issues
without prejudice to any party. While the NRA is correct that a preliminary injunction, at this
point, would not prevent the Final Rule from reaching its effective date, a preliminary injunction
could enjoin implementation or enforcement of the amendments to the regulations at issue.
Thus, the parties’ relative positions could be maintained until resolution of Plaintiffs’ claims on
the merits.

13
 has not intended it to consider, entirely failed to consider an important aspect of
the problem, offered an explanation for its decision that runs counter to the
evidence before the agency, or is so implausible that it could not be ascribed to a
difference in view or the product of agency expertise.

Motor Vehicle Mfrs. Ass’n of the U.S., Inc. v. State Farm Mut. Auto. Ins. Co., 463 U.S. 29, 43

(1983) (citations and internal quotations omitted). This standard of review is deferential to the

agency, and the Court is not entitled to substitute its judgment for that of the agency. Citizens to

Preserve Overton Park, Inc. v. Volpe, 401 U.S. 402, 416 (1971). Nevertheless, while deferential,

“courts are not obliged to stand aside and rubber-stamp their affirmance of administrative

decisions that they deem inconsistent with a statutory mandate or that frustrate the congressional

policy underlying a statute.” Nat’l Labor Relations Bd. v. Brown, 380 U.S. 278, 290 (1965). See

also McDonnell Douglas Corp. v. U.S. Dep’t of the Air Force, 375 F.3d 1182, 1187 (D.C. Cir.

2004) (holding that the “Court will not defer to the agency’s conclusory or unsupported

assertions”).

III. DISCUSSION

Although Plaintiffs assert claims for relief under numerous statutes, the Court need only

reach their principal argument that Defendants should have, but did not, perform an

environmental assessment or environmental impact statement pursuant to the National

Environmental Policy Act. NEPA, the “basic national charter for protection of the environment,”

40 C.F.R. § 1500.1(a), requires federal agencies to take a “hard look” at the environmental

consequences of their projects before taking action. 42 U.S.C. § 4332(C); Marsh v. Or. Natural

Res. Council, 490 U.S. 360, 374 (1989). NEPA “requires that agencies assess the environmental

consequences of federal projects by following certain procedures during the decision-making

14
process.” City of Alexandria, Va. v. Slater, 198 F.3d 862, 866 (D.C. Cir. 1999).

NEPA has twin aims. “First, it places upon an agency the obligation to consider every

significant aspect of the environmental impact of a proposed action.” Baltimore Gas & Elec. Co.

v. Natural. Res. Def. Council, Inc., 462 U.S. 87, 97 (1983) (internal quotation omitted). “Second,

it ensures that the agency will inform the public that it has indeed considered environmental

concerns in its decisionmaking process.” Id. Accordingly, NEPA’s “mandate is essentially

procedural.” City of Alexandria, Va., 198 F.3d at 866 (internal quotation omitted); North Slope

Borough v. Andrus, 642 F.2d 589, 599 (D.C. Cir. 1980) (explaining that NEPA requirements are

essentially procedural and a court should not substitute its own policy judgment for that of the

agency). “NEPA merely prohibits uninformed–rather than unwise–agency action.” Robertson v.

Methow Valley Citizen’s Council, 490 U.S. 332, 351 (1989).

“The major ‘action-forcing’ provision of NEPA is the requirement that ‘all agencies of

the Federal government’ prepare a detailed environmental analysis for ‘major Federal actions

significantly affecting the quality of the human environment.’” Found. on Econ. Trends v.

Heckler, 756 F.2d 143, 146 (D.C. Cir. 1985) (quoting 42 U.S.C. § 4332(C); S. Rep. No. 91-296,

91st Cong., 1st Sess. 19 (1969)). This analysis is called an Environmental Impact Statement

(“EIS”). See 42 U.S.C. § 4332(C).

An EIS is not required if the agency makes a determination based on a more limited

document, an Environmental Assessment (“EA”), that the proposed action would not have a

significant impact on the environment. Sierra Club v. Mainella, 459 F. Supp. 2d 76, 81 (D.D.C.

2006) (citing 40 C.F.R. §§ 1501.4, 1508.13). “The EA is to be a ‘concise public document’ that

‘[b]riefly provide[s] sufficient evidence and analysis for determining whether to prepare an

15
[EIS].’” Dep’t of Transp. v. Pub. Citizen, 541 U.S. 752, 757 (2004) (quoting 40 C.F.R. §

1508.9(a)). “If, pursuant to the EA, an agency determines that an EIS is not required under

applicable [regulations issued by the Council on Environmental Quality], it must issue a ‘finding

of no significant impact’ (“FONSI”), which briefly presents the reasons why the proposed agency

action will not have a significant impact on the human environment.” Id. at 757-58 (citing 40

C.F.R. §§ 1501.4(e), 1508.13).

Of particular significance to the present litigation, an agency need not prepare an EIS or

even an EA if it finds that its proposed action is subject to a “categorical exclusion.” A

“categorical exclusion” is defined as:

a category of actions which do not individually or cumulatively have a significant
effect on the human environment and which have been found to have no such
effect in procedures adopted by a Federal agency in implementation of these
regulations (§ 1507.3) and for which, therefore, neither an environmental
assessment nor an environmental impact statement is required.

40 C.F.R. § 1508.4. The terms within this definition are defined broadly. A “cumulative

impact” is defined as “the impact on the environment which results from the incremental impact

of the action when added to other past, present, and reasonably foreseeable future actions

regardless of what agency . . . or person undertakes such other actions.” Id. § 1508.7. The term

“effects” not only includes direct effects (those “caused by the action and occur at the same time

and place”), but also indirect effects (those “caused by the action and are later in time or farther

removed in distance, but are still reasonably foreseeable”). Id. § 1508.8. Moreover, the type of

“effects” that are contemplated by this definition include:

ecological (such as the effects on natural resources and on the components,
structures, and functioning of affected ecosystems), aesthetic, historic, cultural,
economic, social, or health, whether direct, indirect, or cumulative. Effects may

16
 also include those resulting from actions which may have both beneficial and
detrimental effects, even if on balance the agency believes that the effect will be
beneficial.

Id.

When an agency finds that its proposed action falls within a categorical exclusion, the

agency must then determine whether there are any “[e]xtraordinary circumstances” that

nevertheless require the agency to perform an environmental evaluation. 43 C.F.R. § 46.215.

Such extraordinary circumstances include actions that have

(a) significant impacts on public health or safety,

(b) significant impacts on . . . park, recreation or refuge lands,

(c) highly controversial environmental effects, or

(d) highly uncertain and potentially significant environmental effects or involve
unique or unknown environmental risks.

Id. § 46.215(a)-(d).

Agencies must comply with the procedural requirements of NEPA, and the decision to

forego production of an EIS or EA in favor of a categorical exclusion is subject to judicial review

under the arbitrary and capricious standard of review. Nat’l Trust for Historic Pres. in the U.S.,

828 F.2d at 781; Back Country Horseman of Am. v. Johanns, 424 F. Supp. 2d 89, 98 (D.D.C.

2006) (“an agency’s ‘decision to classify a proposed action as falling within a particular

categorical exclusion will be set aside only if a court determines that the decision was arbitrary

and capricious’”) (quoting Citizens’ Comm. to Save Our Canyons v. U.S. Forest Serv., 297 F.3d

1012, 1023 (10th Cir. 2002)).

With this background in place, the Court shall turn to Plaintiffs’ showing with respect to

17
the four elements necessary to obtain a preliminary injunction.

A. Plaintiffs’ Have Established a High Likelihood of Success on the Merits

The DOI promulgated the Final Rule without conducting an EIS or an EA, taking the

position that the Final Rule was subject to a categorical exclusion for regulations of a purely legal

nature:

[p]olicies, directives, regulations, and guidelines: that are of an administrative,
financial, legal, technical, or procedural nature; or whose environmental effects
are too broad, speculative, or conjectural to lend themselves to meaningful
analysis and will later be subject to the NEPA process, either collectively or case-
by-case.

43 C.F.R. § 46.210(i).10

The DOI’s November 18, 2008 Decision Memorandum describes four reasons why it

believed this categorical exclusion applied to the Final Rule. See Decision Mem. at 3-4. First,

the DOI believed that the Final Rule was “strictly [a] legal amendment” that “amends existing

regulations to allow visitors to carry concealed, loaded, and operable firearms in federal park

units and wildlife refuges to the extent that they could lawfully do so under non-conflicting state

law.” Id. at 3. Second, the DOI concluded that the Final Rule “will not have any actual effects

on the environment” because “the [F]inal [R]ule does not authorize any actual impacts on the

10
Plaintiffs’ Motion for a Preliminary Injunction argues that the DOI improperly relied on
the language of this categorical exclusion after it had been amended in October 2008. See Pls.’
Mot. at 17-18. Whereas the categorical exclusion previously applied to regulations of a legal
nature “and whose environmental effects are too broad,” the categorical exclusion was amended
to apply to regulations of a legal nature “or whose environmental effects are too broad.”
(emphasis added). The DOI explained that this change was made to correct “an unintended
drafting error,” 73 Fed. Reg. 61292 (Oct. 15, 2008), and Plaintiffs do not suggest that this
change, published in a proposed rule on January 2, 2008, was procedurally improper. As
Defendants correctly note, Plaintiffs “cite no authority for [the] proposition that an agency cannot
rely on a recently amended regulation after it has become effective.” Defs.’ Opp’n at 24 n.18.

18
environment.” Id. (emphasis in original). Third, the DOI explained that the Bureau of Land

Management (“BLM”) and the United States Forest Service already authorize the possession of

concealed firearms on public lands in accordance with state laws, and that “available data does

not suggest that visitors to these lands use legally permitted firearms for poaching or illegal

shooting, or that there is additional danger posed to the public from lawfully carried concealed

firearms.” Id. at 4 (citing various reports, studies, and surveys). Fourth, the DOI emphasized

that the Final Rule “explicitly maintains existing prohibitions on poaching, target shooting, and

other illegal uses of firearms, including laws against brandishing a firearm in public,”

prohibitions that the DOI “expects visitors to obey.” Id.

Plaintiffs argue that none of these reasons justify the DOI’s failure to assess the

environmental impacts of the Final Rule. Specifically, Plaintiffs argue that the DOI avoided

“study or analysis of how many loaded guns are likely to be carried into National Parks and how

they will be used,” and “just assum[ed] that none of the guns will ever be fired . . . .” Pls.’ Mot.

at 20. Brady also points out that Defendants “never explain why it is crucial to reverse a

longstanding public safety rule to allow people to carry loaded firearms that they supposedly will

never use, or on what basis they presume that those carrying firearms will never brandish or use

them.” Brady Reply at 20.

The Court agrees with Plaintiffs that the DOI’s Decision Memorandum reflects a

significant misunderstanding of the obligations imposed by NEPA. Under that statute, the DOI

was required to take a “hard look” at the environmental consequences of the Final Rule before its

implementation. Marsh, 490 U.S. at 374. This burden is greater than simply examining whether

environmental impacts are authorized by the Final Rule – the DOI was required to consider all

19
direct, indirect, and cumulative impacts that were foreseeable as a result of the Final Rule. See

40 C.F.R. § 1508.8 (defining “indirect effects” to include those that are “reasonably

foreseeable”).

For example, in Friends of the Earth, Inc. v. United States Army Corps of Engineers, the

defendant (the “Corps”) performed two EA’s in connection with a proposal to construct three

casinos on large floating barges along Mississippi’s St. Louis Bay and the Bay of Biloxi. 109 F.

Supp. 2d 30, 32-33 (D.D.C. 2000). The Corps found that there would be no significant impact

on the environment as a result of the construction, in part based on a finding that indirect

“growth-inducing effects” were “‘highly speculative and indefinite.’” Id. (quoting Sierra Club v.

Marsh, 769 F.2d 868, 878 (1st Cir. 1985)). The plaintiffs argued, in contrast, that the Corps was

required under NEPA to evaluate “the significant upland development adjacent to the casino

barges and the inevitable secondary development that would result from the casinos.” Id. at 40.

The court agreed with the plaintiffs, finding that “[i]ndirect impacts need only to be

‘reasonably foreseeable’ to require an assessment” under NEPA. Id. at 41. The court reviewed

the administrative record and found that it established “that increased growth in the area is the

only reasonable prediction of what will occur if the casinos are built,” and emphasized that “the

Corp’s own leadership has acknowledged that increased development resulting from the casinos

is a concern.” Id. at 41. Accordingly, it made no difference whether the casinos themselves were

the source of these effects, provided the construction of the casinos would give rise to these

foreseeable effects.

The analysis in Friends of the Earth, Inc., which reaffirmed an agency’s obligation to

evaluate all reasonable foreseeable environmental impacts and not just those authorized by an

20
agency action, is also reflected (ironically) in one of two cases cited by the DOI in its Decision

Memorandum seeking to justify reliance on a categorical exclusion. See Decision Mem. at 3

(citing Sierra Club v. Bosworth, 510 F.3d 1016 (9th Cir. 2007)).11 In that case, the Ninth Circuit

Court of Appeals found that the United States Forest Service failed to properly assess the

environmental significance of a categorical exclusion for certain fuel reduction projects in all

national forests in the United States. 510 F.3d at 1027. In so finding, the court held that the

Forest Service “failed to consider adequately the unique characteristics of the applicable

geographic areas, the degree to which effects on the quality of the environment were

controversial or the risks were unknown . . . and whether there existed cumulative impacts from

other related actions.” Id. Although the Forest Service analyzed various data prior to

establishing the categorical exclusion, the court found that its evaluation was “inadequate as a

cumulative impacts analysis because it offer[ed] only conclusory statements that there would be

no significant impact[s].” Id. at 1029. The court further rejected the Forest Services’s approach

for assessing foreseeable environmental impacts in which the Forest Service “summarily

conclude[d], without citing hard data to support its conclusion, that there were no cumulative

impacts” because “this is precisely the reason why a global cumulative impact analysis must be

performed.” Id.

The DOI made the same error in this case that the defendants made in Friends of the

Earth, Inc. and Sierra Club. Rather than performing an evaluation to ascertain the extent of any

foreseeable environmental impacts, the DOI simply assumed there were none because the Final

11
The second of the two cases, California v. Norton, 311 F.3d 1162, 1172 (9th Cir.
2002), concerns the extraordinary circumstances that prevent an agency from relying on a
categorical exclusion.

21
Rule did not authorize any impacts. See Decision Mem. at 2 (“the final rule does not authorize

any actual impacts on the environment, and thus meets the test for a categorical exclusion under

relevant regulations and judicial precedent”) (citing Sierra Club v. Bosworth, 510 F.3d 1016 (9th

Cir. 2007)). This Court’s function is to “ensure that the agency has adequately considered and

disclosed the environmental impact of its actions and that its decision is not arbitrary or

capricious.” City of Olmsted Falls, Ohio v. Fed. Aviation Admin., 292 F.3d 261, 269 (D.C. Cir.

2002). The scope of this review includes an inquiry into whether the agency has made its

decision based on “a consideration of the relevant facts” and whether it has “failed to consider an

important aspect” of the issues associated with its decision. Motor Vehicle Mfrs. Ass’n, 463 U.S.

at 43. Defendants’ failure to apply the correct standard by which to consider environmental

impacts–by examining what the Final Rule authorized as opposed to the foreseeable

consequences that would occur as a result of the Final Rule–is sufficient by itself to render the

DOI’s decision to invoke a categorical exclusion arbitrary and capricious.12 While this error

alone would provide Plaintiffs with a high likelihood of success on the merits of their NEPA

claims, this improper standard was only the first of several procedural errors committed by the

DOI.

The DOI also ignored, without any explanation, its own long-standing belief under the

previous regulations that firearm restrictions in national parks and wildlife refuges were

necessary to “ensure public safety and provide maximum protection of natural resources by

12
Were the Court to adopt Defendants’ logic, a rule that amended regulations to allow
persons to dump containers of toxic waste in national parks could qualify for a categorical
exclusion as an amendment of a “legal nature,” provided the rule also required that the containers
not leak or otherwise have an impact on the environment.

22
limiting the opportunity for unauthorized use of weapons.” 48 Fed. Reg. at 30,265. Public safety

and protection of natural resources are indisputably encompassed within the definition of

“environmental impacts” that must be considered pursuant to NEPA. See 40 C.F.R. § 1508.8

(defining environmental impacts to include “ecological, . . . aesthetic, historic, cultural,

economic, social, or health,” effects, “whether direct, indirect, or cumulative”).13 Nonetheless,

Defendants point to nothing in the Administrative Record to show why they believe their

previous environmental concerns have subsided over time or why they are, in fact, no longer

concerns.

Plaintiffs emphasize that the DOI failed to distinguish its previous position that gun

restrictions were a “basic mechanism . . . to protect the natural and cultural resources of the parks

[and wildlife refuges] and to protect visitors and property within the parks.” Pls.’ Mot. at 26-27

(quoting 48 Fed. Reg. at 30252). Plaintiffs argue that the DOI’s “only mention of the prior rules

was a description of how they operated,” Pls.’ Mot. at 26, and that this brief mention was

insufficient to justify a reversal of its previous position. Id. at 25.

The D.C. Circuit has repeatedly explained that an agency’s unexplained “180 degree turn

away from [precedent is] arbitrary and capricious,” and that an agency’s decision “to reverse its

position in the face of a precedent it has not persuasively distinguished is quintessentially

arbitrary and capricious.” La. Pub. Serv. Comm’n v. Fed. Energy Regulatory Comm’n, 184 F.3d

892, 897 (D.C. Cir. 1999) (citing Motor Vehicle Mfrs. Ass’n, 463 U.S. at 57) (“[a]n agency’s

view of what is in the public interest may change, either with or without a change in

23
circumstances. But an agency changing its course must supply a reasoned analysis”). “‘[T]he

core concern underlying the prohibition of arbitrary and capricious agency action’ is that agency

‘ad hocery’ is impermissible.” Ramaprakash v. Fed. Aviation Admin. & Nat’l Transp. Safety

Bd., 346 F.3d 1121, 1130 (D.C. Cir. 2003) (quoting Pacific N.W. Newspaper Guild, Local 82 v.

Nat’l Labor Relations Bd., 877 F.2d 998, 1003 (D.C. Cir. 1989)). See also ANR Pipeline Co. v.

Fed. Energy Regulatory Comm’n, 71 F.3d 897, 901 (D.C. Cir. 1995) (“Where an agency departs

from established precedent without a reasoned explanation, its decision will be vacated as

arbitrary and capricious.”).

Relying on this guidance, lower courts have repeatedly inquired into whether an agency

has adequately explained a change in its position in light of the obligations imposed by NEPA.

See, e.g., Greater Yellowstone Coal. v. Kempthorne, 577 F. Supp. 2d 183, 189 (D.D.C. 2008)

(“[r]eview of an agency action is more demanding where the challenged decision stems from an

administrative about-face”); Fund for Animals v. Norton, 294 F. Supp. 2d 92, 107 (D.D.C. 2003)

(invalidating a rule permitting 950 snowmobiles in national parks each day because NPS failed to

adequately distinguish its previous position that “snowmobiling so adversely impacted the

wildlife and resources of the Parks that all snowmobile use must be halted”).

Here, the Court finds that the DOI failed to adequately distinguish its previous position

that firearm restrictions were necessary to protect against environmental harms involving “public

safety” and “protection of natural resources.” Based on its Decision Memorandum, the DOI

appears to have been singularly motivated to lift the restrictions that prevented persons from

carrying concealed, loaded, and operable firearms in national parks and wildlife refuges based on

considerations of federalism:

24
 [w]e believe that in managing parks and refuges we should, as appropriate, make
every effort to give the greatest respect to the democratic judgments of State
legislatures with respect to concealed firearms. As stated in the proposed rule,
Federal agencies have a responsibility to recognize the expertise of the States in
this area, and Federal regulations should be developed and implemented in a
manner that respects ‘state prerogatives and authority.’

73 Fed. Reg. at 74,967 (quoting Executive Order 13132 (Aug. 10, 1999)).

Even if one were to accept this explanation,14 the DOI’s federalism concerns are unrelated

to, and have no effect on, any environmental impacts associated with the Final Rule. Defendants

have not suggested otherwise, simply assuming (as set forth above), that the Final Rule will have

no environmental impacts because none have been authorized, even though Defendants took the

position until recently that firearm restrictions contained in the previous regulations were

necessary to protect against environmental harms. This change of course without a reasoned

explanation is the quintessential example of an arbitrary and capricious action. Defendants were

required to provide a reasoned explanation for the Final Rule that addressed all foreseeable

environmental impacts – including those that the DOI has already foreseen, as reflected in the

previous regulations.

14
There are substantial reasons to question both the logic and efficacy of the DOI’s
explanation. According to Brady, there are twenty-five states “that prohibit the transport of
concealed and loaded guns within their own parks.” See Brady Reply at 13 & n.12. Given that
the Final Rule lifts firearm restrictions in national parks or wildlife refuges in accordance with
state law generally (as opposed to the laws applied to the state parks and wildlife refuges located
in those states), the Final Rule appears to permit concealed firearms in the national parks or
wildlife refuges of some states that do not allow concealed firearms in their own state parks or
wildlife refuges. This discrepancy is highlighted by the FOA Amicus Brief, which explains that
the Final Rule creates precisely this anomaly in the state of Maine. See FOA Amicus Br. at 4.
Accordingly, in FOA’s view, the Final Rule “actually allow[s] the national government to
impose its will on states, despite long-standing state laws to the contrary.” Id. While Defendants
object to this characterization of the Final Rule, they do not fully dispute that this discrepancy
exists. See Defs.’ Sur-Reply at 4. In any event, the Court need not resolve the merits of
Defendants’ federalism explanation to rule on Plaintiffs’ Motion for a Preliminary Injunction.

25
 Finally, there is a third flaw associated with the DOI’s decision to invoke a categorical

exclusion. Despite the DOI’s obligation to take a “hard look” at the environmental impacts

associated with the Final Rule, and even though an EA is the appropriate vehicle to initially

assess such environmental impacts, the DOI’s Decision Memorandum proceeds to highlight

various information in the administrative record that, according to the DOI, demonstrates that the

Final Rule will not lead to any environmental impacts:

the BLM and the U.S. Forest Service currently authorize the possession of
concealed firearms consistent with the laws of the state in which they are located.
The available data [which is not defined or further explained] does not suggest
that visitors to these lands use legally permitted firearms for poaching or illegal
shooting, or that there is additional danger posed to the public from lawfully
carried concealed firearms.

Decision Mem. at 4 (citing Firearms and Violence: A Critical Review 6 (Charles F. Wellford et

al. eds., 2004)). The DOI’s Decision Memorandum then references “a number of academic

studies and surveys demonstrat[ing] that individuals authorized to carry concealed firearms are

less likely than the general public to commit a violent crime or engage in a personal confrontation

with a firearm.” Id. (emphasis in original). Defendants’ Opposition to Plaintiffs’ Motion for a

Preliminary Injunction repeats this information without further elaboration. See Defs.’ Opp’n at

13-14.

The deficiencies with the DOI’s analysis are numerous. First, the conclusion that there

will be no environmental impacts associated with the Final Rule is inconsistent with the almost

universal view reflected in the administrative record (including among Defendants) that allowing

concealed, loaded, and operable firearms in national parks and wildlife refuges will result in

persons using them, particularly for self-defense:

26
 From the DOI:

Issue 5: Visitors should not carry a concealed firearm for self-defense because
NPS and FWS law enforcement officers are more than adequate to protect
individuals from harm:

Response 5: The Department believes that NPS and FWS law enforcement
officers work hard and perform valiant public service in their respective
capacities. We also recognize that the NPS and FWS together employ
approximately 3,000 full and part-time law enforcement officers who are
responsible for patrolling and securing millions of acres of land, a substantial
portion of which is remote wilderness. In these circumstances, NPS and FWS law
enforcement officers are in no position to guarantee a specific level of public
safety on their lands, and cannot prevent all violent offenses and crimes against
visitors.

73 Fed. Reg. at 74,969.

From Intervenor-Defendant NRA:

[d]efensive gun use is very common, with as many as 2.5 million defensive gun
uses per year. Gun use is more effective than any other means for preventing the
completion of robberies and assaults, and people who use guns in self-defense are
significantly less likely to be injured during a robbery or assault than are victims
who respond in any other way.

NRA Mot. to Intervene, Ex. A at 3 (6/30/08 Comments on Proposed Rule).

From Amicus Curiae SCI:

sportsmen and women are direct beneficiaries of the Final Rule. Many hunters
and fisherman, or their guides, carry a loaded pistol as protection against large
predators, including bears and wolves. A preliminary injunction would take away
the ability of sportsmen and women to defend themselves from wildlife in remote
areas of National Parks and Refuges.

SCI Amicus Br. at 13.

From every living former Director of the National Park Service:

we are concerned about efforts to overturn the regulations controlling firearms in
the national parks . . . These rules . . . are essential to park rangers in carrying out
their duties of protecting park resources and wildlife, and in assuring the safety of

27
 visitors to the parks . . . The regulation was crafted to be as narrowly restrictive as
possible while assisting park personnel to prevent unlawful killing of wildlife.

A.R. 1218 (4/3/08 Letter to D. Kempthorne).

From various individuals submitting comments to the DOI:

I [] go back packing and would like to be able to carr[ry] my fire arm [sic] with
me for possible wild animal attack.

I urge you to change the rules on carrying guns into the National Parks, for those
of us who have conceal[ed] carry permits, we carry [firearms] for the protection of
our families and self from those who would do us harm. We are not looking to
shoot anyone unless we are forced to in order to protect our family.

A.R. 1927 (6/16/08 Email Comment), A.R. 56009 (8/7/08 Public Submission).

From Plaintiff NPCA:

that defensive shootings–whether justified or not, whether hit or miss–will occur
is not reasonably open to debate. Scores of individuals with concealed carry
permits have made their intent to use weapons in perceived self-defense in the
National Parks crystal clear.

NPCA Reply at 5. Despite this view, there is no indication in the administrative record that

Defendants evaluated (1) the likely number of concealed, loaded, and operative firearms that

would be brought into national parks and wildlife refuges, (2) the likely number of instances the

firearms would be discharged or otherwise used (including for defensive purposes), and (3) the

likely effect on the environment.

The failure to fully consider an environmental impact has long been held to be arbitrary

and capricious under the procedures set forth in NEPA. For example, in Foundation on

Economic Trends v. Heckler, the D.C. Circuit examined whether the National Institute of Health

(“NIH”) had performed the appropriate level of environmental review prior “to approving the

deliberate release of genetically engineered, recombinant-DNA-containing organisms into the

28
open environment.” 756 F.2d 143, 145 (D.C. Cir. 1985). Although NIH performed two EA’s,

the Court found that NIH’s consideration fell “far short of the NEPA requirements.” Id. at 153.

The Court explained that “dispersion of genetically altered organisms are uncertain. Some

observers believe that such dispersion would affect the environment and the climate in harmful

ways.” Id. The Court then explained that NIH’s only consideration of these environmental

impacts consisted of a single sentence: “[a]lthough some movement of bacteria toward sites near

treatment locations by insect or aerial transport is possible, the numbers of viable cells

transported has been shown to be very small.” Id. at 153 (emphasis in original). The Court

found that NIH “failed to consider the possible environmental impact from dispersion of

genetically altered bacteria,” and “[a]n environmental assessment that fails to address a

significant environmental concern can hardly be deemed adequate for a reasoned determination .

. . .” Id. at 153-54. The D.C. Circuit then stated, in no uncertain terms, that ignoring possible

environmental impacts, or explaining in conclusory form that they are not of concern, is

insufficient under NEPA:

Ignoring possible environmental consequences will not suffice. Nor will a mere
conclusory statement that the [environmental impacts] will be small . . . Nor is it
sufficient for the agency merely to state that the environmental effects are
currently unknown. Indeed, one of the specific criteria for determining whether
an EIS is necessary is ‘the degree to which the possible effects on the human
environment are highly uncertain or involve unknown risks.’

Id. at 154-55 (citing 40 C.F.R. § 1508.27(b)(5). Like the NIH in Heckler, the DOI arbitrarily and

capriciously ignored the environmental impacts that would result from the use of these firearms.

Defendants repeatedly argue in their briefs that no assessment of firearm use was

necessary because the use is based on “speculation.” See, e.g., Defs.’ Opp’n at 13. The DOI’s

29
explanation is woefully insufficient because NEPA requires an agency to consider environmental

impacts even if the effects are not entirely certain. “Simply by focusing the agency’s attention on

the environmental consequences of a proposed project, NEPA ensures that important effects will

not be overlooked or underestimated only to be discovered after resources have been committed

or the die otherwise cast.” Robertson v. Methow Valley Citizens Council, 490 U.S. 332, 349

(1989). This has been a long-standing principle reflected in the case law of this circuit:

[t]he agency need not foresee the unforeseeable, but by the same token neither can
it avoid drafting an impact statement simply because describing the environmental
effects of and alternatives to a particular agency action involves some degree of
forecasting. And one of the functions of a NEPA statement is to indicate the
extent to which environmental effects are essentially unknown. It must be
remembered that the basic thrust of an agency’s responsibilities under NEPA is to
predict the environmental effects of proposed action before the action is taken and
those effects are fully known. Reasonable forecasting and speculation is thus
implicit in NEPA . . . .

Scientists’ Inst. for Pub. Info. v. Atomic Energy Comm’n, 481 F.2d 1079, 1092 (D.C. Cir. 1973).

The cases cited by Defendants in support of their “speculation” argument are inapposite.

Defendants cite Kleppe v. Sierra Club, 427 U.S. 390 (1976), and two other cases for the

proposition that “agencies are not required to evaluate impacts that are speculative.” Defs.’

Opp’n at 18. In actuality, Kleppe and these other cases stand for the very different principle that

an agency need not consider environmental impacts when its own action is speculative or

hypothetical. That is, the question in those cases was not whether the environmental impacts of a

particular action were speculative, but rather, whether the agency was, in fact, going to take a

particular action in the future. See, e.g., Kleppe, 427 U.S. at 408-09 (holding that an EIS was not

required where there was no evidence in the record that the agencies were contemplating a

proposal for a major federal action with respect to the region at issue). In this case, there is no

30
question that the DOI has acted because the Final Rule has already been implemented. Similarly,

Defendant cites Glass Packaging Institute v. Regan, 737 F.2d 1083, 1092-94 (D.C. Cir. 1984),

for the proposition that NEPA does not require consideration of environmental effects caused by

the “criminal acts of third parties.” Defs.’ Opp’n at 18. That case, however, supports the more

modest principle that an act need not be evaluated if it is not “an environmental health risk.” Id.

at 1092. That case did not circumscribe the well-settled rule that an agency must evaluate

foreseeable environmental impacts even if they are the result of the yet-unknown actions of third

parties:

NEPA’s impact statement procedure has been held to apply where a federal
agency approves a lease of land to private parties, grants licenses and permits to
private parties, or approves and funds state highway projects. In each of these
instances the federal agency took action affecting the environment in the sense
that the agency made a decision which permitted some other party – private or
governmental – to take action affecting the environment.

Scientists’ Inst. for Pub. Info., 481 F.2d at 1088-89.

Beyond the failure to evaluate these potential environmental impacts, the DOI’s reliance

on the experiences of the BLM and the Forest Service, as well as its citation to the National

Research Council study cited in its Decision Memorandum, are inadequate. See Decision Mem.

at 4. The DOI’s reference to “available data” is entirely unexplained and the Court shares

Plaintiffs’ confusion as to whether the DOI was relying on the studies cited only in its Decision

Memorandum or on actual data compiled by the BLM and the Forest Service concerning how its

regulations have operated. See NPCA Reply at 8 (“the only ‘data’ cited are . . . academic studies

. . . Plaintiffs have not found any evidence in the Final Rule or in the Administrative Record that

Defendants ever attempted to gather any relevant data from BLM or the Forest Service”).

31
Defendants’ citation to Firearms and Violence: A Critical Review is also puzzling. See Decision

Mem. at 4. The DOI’s citation refers to the conclusion that certain data does not “credibly

demonstrate a causal relationship between the ownership of firearms and the causes or prevention

of criminal violence or suicide.” A.R. 808 (Firearms and Violence: A Critical Review 6 (Charles

F. Wellford et al. eds., 2004)). The report also concludes, however, that “far less attention has

been devoted to understanding the defensive and deterrent effects of firearms,” id. – precisely the

usage that is likely to occur according to the information in the Administrative Record.

Defendants’ statement that “a number of academic studies and surveys demonstrate that

individuals authorized to carry concealed firearms are less likely than the general public to

commit a violent crime or engage in a personal confrontation with a firearm,” reflects another

misunderstanding for what the DOI should have evaluated prior to promulgating the Final Rule.

A.R. 201 (emphasis in original). Even if the DOI’s conclusion were entirely correct, it makes no

difference whether persons carrying concealed weapons are more or less likely to commit crimes

or engage in personal confrontations than the general public. What does matter is how often such

acts will occur when concealed, loaded, and operative firearms are brought into national parks

and wildlife refuges, and what result such actions will have on the environment. Stated another

way, the issue as it relates to NEPA is not whether persons carrying concealed firearms will use

them more often than the general public, but rather, whether they will use them at all. If the

firearms will be used, then the Final Rule will obviously have some impact on the environment,

whether direct, indirect, or cumulative. Defendants improperly ignored this environmental

impact.

Given the foregoing, the Court finds that the DOI’s decision to invoke a categorical

32
exclusion was arbitrary and capricious.15 Categorical exclusions are reserved for a category of

agency actions that “do not individually or cumulatively have a significant effect on the human

environment and which have been found to have no such effect . . . .” 40 C.F.R. § 1508.4.

Defendants reached their determination that the Final Rule was strictly a legal amendment with

no environmental impacts only after failing to adequately evaluate all reasonably foreseeable

environmental impacts, and ignoring (without sufficient explanation) substantial information in

the administrative record concerning environmental impacts. Those environmental impacts

include Defendants’ own long-standing beliefs under the previous regulations that such

environmental impacts would occur in the absence of firearm restrictions and the almost

universal view among interested parties that allowing persons to possess concealed, loaded, and

operable firearms in national parks and wildlife refuges will result in the use of the firearms for

self-defense or any number of other reasons.

The Court further holds, for precisely the same reasons, that the DOI also improperly

determined that there were no “extraordinary circumstances in which a normally excluded action

may have a significant environmental effect,” thus requiring preparation of at least an EA. 40

C.F.R. § 1508.4. In this case, the information in the administrative record makes clear that a

substantial dispute exists with respect to the environmental effects of the Final Rule, and that

such effects may have a significant impact on public health or safety. Id. § 1508.27.

Accordingly, the Court finds that Plaintiffs have a high likelihood of success on the

15
Plaintiffs also argue that Defendants violated NEPA by failing to solicit public
comments for their decision to invoke a categorical exclusion. See Pls.’ Mot. at 16-19. As
described by Defendants, no such requirement exists in NEPA or applicable regulations. See
Defs.’ Opp’n at 20-24.

33
merits of their NEPA claims.

B. Plaintiffs Have Established a Likelihood of Irreparable Harm in the Absence of a
Preliminary Injunction

Defendants’ Opposition to Plaintiffs’ Motion for Preliminary Injunction argues that

Plaintiffs cannot establish that they will suffer irreparable injury in the absence of a preliminary

injunction. See Defs.’ Opp’n at 10-13. This argument is premised on Defendants’ assertion that

“Plaintiffs obviously are speculating about potential injury,” Defs.’ Opp’n at 33, and “the only

imaginable way [] alleged implementation difficulties could amount to an irreparable injury to

Plaintiffs would be through the realization of Plaintiffs’ speculation about increased illegal gun

use.” Defs.’ Opp’n at 34. Defendants also argue that “Plaintiffs make no showing whatsoever

that illegal gun activity or impulse killings is likely . . . As explained above, the Final Rule does

not authorize ‘increased gun activity,’ and leaves in place all the existing prohibitions on illegal

gun activity.” Defs.’ Opp’n at 33 (emphasis in original omitted).

For the reasons described above, the Court has already found that the DOI

misapprehended its obligations under NEPA by focusing on what the Final Rule authorized, as

opposed to what environmental impacts were foreseeable. See, Section III.A, supra. Although a

procedural violation of NEPA is not itself sufficient to establish irreparable injury, it is certainly

a relevant consideration:

[t]he NEPA duty is more than a technicality; it is an extremely important statutory
requirement to serve the public and the agency before major federal actions occur.
If plaintiffs succeed on the merits, then the lack of an adequate environmental
consideration looms as a serious, immediate, and irreparable injury. Although the
balancing of this harm against other factors is necessarily particularized, the
injury itself is clear.

Found. on Econ. Trends, 756 F.2d at 157 (emphasis in original; internal citations omitted).

34
When a procedural violation of NEPA is combined with a showing of environmental or aesthetic

injury, courts have not hesitated to find a likelihood of irreparable injury. See, e.g., Fund for

Animals v. Norton, 281 F. Supp. 2d 209, 221 (D.D.C. 2003) (“although defendants appear to be

correct in their assertion that the procedural harm arising from a NEPA violation is insufficient,

standing alone, to constitute irreparable harm justifying issuance of a preliminary injunction,

when combined with the irreparable aesthetic injuries alleged by plaintiffs, such procedural harm

does bolster plaintiffs’ case for a preliminary injunction”) (emphasis in original); Fund for

Animals v. Clark, 27 F. Supp. 2d 8, 14 (D.D.C. 1998) (“the combination of the injury suffered by

plaintiffs due to federal defendants’ procedural failure to comply with NEPA and the aesthetic

injury the individual plaintiffs would suffer from seeing or contemplating the bison being killed

in an organized hunt leads the court to conclude that the plaintiffs have carried their burden of

demonstrating the presence of an irreparable harm should the court not grant injunctive relief”).

In this case, Plaintiffs have met their burden to establish a likelihood of irreparable harm

by showing that the Final Rule will have some environmental impacts, even if the extent of those

impacts are not fully known. See Section III.A, supra (describing the almost universal view in

the administrative record that persons carrying the concealed, loaded, and operable firearms in

national parks and wildlife refuges will use them for self-defense or otherwise); 40 C.F.R. §

1508.8 (defining environmental impacts to include “ecological, . . . aesthetic, historic, cultural,

economic, social, or health,” effects, “whether direct, indirect, or cumulative”). In addition,

Brady has submitted declarations from several of its members indicating that they are now

concerned for their personal safety in parks and refuges and cannot fully enjoy their visits to

certain national parks or wildlife refuges because they feel less safe. See Brady Reply at 20-22 &

35
Exs. G-P (Brady Member Declarations). These environmental and aesthetic injuries are

irreparable. See Amoco Prod. Co. v. Vill. of Gambell, 480 U.S. 531, 545 (1987) )

(“‘[e]nvironmental 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’”); Envtl. Def. v. Army Corps

of Eng’rs, No. 04-1575, 2006 U.S. Dist. LEXIS 47969 at *25-*26 (D.D.C. Jul. 14, 2006)

(“[b]ecause of the irremediable nature of many environmental claims, courts have been wary of

even relatively modest environmental harm”); Fund for Animals, 27 F. Supp. 2d at 14 (finding

aesthetic injury that demonstrated irreparable harm where “[a]t least one of the individual

plaintiffs has in the past traveled great distances . .. for purposes of observing the visiting with

the bison” that were the subject of the potential agency action”).

The Court also finds, contrary to Defendants’ argument, that Plaintiffs’ injuries are not

minimized or eliminated simply because the precise effects of the Final Rule are unknown. See

Defs.’ Opp’n at 33. See also MSLF Opp’n at 7 (arguing that Plaintiffs “are unable to provide

evidence that the Final Rule will ‘imminently’ cause widespread loss of wildlife . . .”). This lack

of precision is the result of the DOI’s failure to conduct an environmental evaluation prior to

promulgating the Final Rule, and it does not constitute an impediment to Plaintiffs’ showing of

irreparable harm. See Winter, 129 S. Ct. at 376 (“[p]art of the harm NEPA attempts to prevent in

requiring an EIS is that, without one, there may be little if any information about prospective

environmental harms and potential mitigating measures”); Fund for Animals v. Norton, 281 F.

Supp. 2d 209, 221 (D.D.C. 2003) (“District Court [have] found irreparable harm in . . . cases

even though plaintiffs did not establish that the exact animals they regularly observed would be

36
directly affected by the proposed action”).16

Accordingly, the Court finds that Plaintiffs have met their burden to establish a likelihood

of irreparable harm, even though the precise scope of that harm may not be fully known unless

and until Defendants comply with the procedural obligations imposed by NEPA.

C. Plaintiffs Have Established that a Preliminary Injunction is Not Likely to Injure
Defendants, and the Potential Harm to Other Interested Parties is Not Substantial

Defendants do not argue that they will suffer any harm as a result of a Preliminary

Injunction. See generally Defs.’ Opp’n. See also NPCA Reply at 22 (“Defendants have offered

no explanation or argument of any harms that would befall them if an injunction issued”); Brady

Reply at 22 (“Defendants have failed to show, or even assert, that they will sustain any harm

whatsoever if this Court grants a preliminary injunction”).

Intervenor-Defendants NRA and MSLF argue that their members will suffer injuries if a

preliminary injunction issues because they want to possess concealed, loaded, and operable

firearms in national parks and wildlife refuges. See, e.g., NRA Opp’n at 24 (“millions of law-

abiding people [want] to exercise lawfully their rights created by state law to carry firearms on

federal lands”). These injuries, however, are somewhat diminished by the uncertainty as to

whether their members have such a right at all based on the Final Rule implemented by

Defendants. Neither the NRA nor MSLF present the Court with any reason as to why, after

16
The Court notes that Defendants’ Opposition contains a lengthy argument about who
bears the burden of proving irreparable harm. See Defs.’ Opp’n at 33 (“Plaintiffs are confused
about who bears the burden to justify a preliminary injunction. It is Plaintiffs’ burden to
demonstrate injury . . .”). Defendants’ argument is misguided. Plaintiffs have only suggested
that Defendants’ failures under NEPA have deprived them of the ability to set forth a precise
showing of the extent of environmental harm, see Pls.’ Mot. at 38, but in no way do they suggest
that Defendants bear the burden of establishing the likelihood of Plaintiffs’ irreparable injuries.

37
operating under the firearm restrictions in the previous regulations for approximately 25 years,

their members would be substantially harmed while awaiting resolution of Plaintiffs’ claims on

the merits and ascertainment of whether their members have the right to possess concealed,

loaded, and operable firearms in national parks and wildlife refuges based on the regulations

amended by the Final Rule.

Accordingly, while the Court accepts that the MSLF and the NRA’s members may suffer

some harm by having to wait to possess concealed, loaded, and operable firearms in national

parks and wildlife refuges in accordance with the regulations amended by the Final Rule, the

Court finds that this harm (which is limited in time by the pendency of these proceedings) is not

substantial, and that there is no harm to Defendants themselves.

D. Plaintiffs Have Shown that a Preliminary Injunction Is in the Public Interest

There is no question that the public has an interest in having Congress’ mandates in

NEPA carried out accurately and completely. See 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.”). The public also has an interest in ensuring that the Final Rule

promulgated by the DOI does not give way to unintended environmental consequences that have

not (but should have) been evaluated by Defendants. As Brady points out, a preliminary

injunction will ensure that the DOI’s original goals of “ensur[ing] public safety and provid[ing]

maximum protection of natural resources” are not undermined by environmental impacts that

have not yet been properly considered. Brady Reply at 24 (quoting 47 Fed. Reg. at 11,602; 48

38
Fed. Reg. at 30,265).

Defendants have not set forth any reason as to why the Final Rule must be implemented

at this time, as opposed to after a resolution on the merits of Plaintiffs’ claims. Cf. Fund for

Animals v. Norton, 281 F. Supp. 2d 209, 237 (D.D.C. 2003) (“[defendants] have not met their

burden of demonstrating why reduction of the mute swan population in Maryland must begin at

this time in order to achieve this long-term goal, as opposed to, say, a year in the future when the

next molting season takes place”) (emphasis in original). Although the MSLF argues that the

amorphous “constitutional guarantees of federalism” are best served by not enjoining

implementation and enforcement of the Final Rule, see MSLF Opp’n at 22-23, the MSLF

similarly does not argue that federalism cannot await resolution of Plaintiffs’ claims on the

merits in this case. Should Defendants ultimately prevail in this litigation, it would appear that

little would have been lost, and implementation of the Final Rule (and the experiment in

federalism discussed by the MSLF) could follow shortly thereafter.17

Having considered Plaintiffs’ showing with respect to the four elements necessary to

obtain preliminary injunctive relief, having conducted a balancing of the equities, and having

taken into account the totality of the circumstances as a whole, the Court finds that Plaintiffs

have made the necessary showing to obtain a preliminary injunction.

17
The Court notes that the NRA includes certain arguments in its brief relating to the
constitutional right to bear arms. See NRA Opp’n at 14. It is unclear whether the NRA intended
to argue that the regulations in place prior to the Final Rule unconstitutionally infringe on the
rights of its members. Nevertheless, the Court emphasizes that this case is not a referendum on
concealed weapons laws, and the constitutionality of the regulations in place prior to the Final
Rule are not before this Court.

39
 E. Standing

As a final matter, the Court shall address the issue of Plaintiffs’ standing. Although the

Court recognizes that standing is ordinarily examined as a threshold jurisdictional issue, see

Raytheon Co. v. Ashborn Agencies, Ltd., 372 F.3d 451, 453 (D.C. Cir. 2004) (“Article III

standing must be resolved as a threshold matter”), Defendants have not challenged Plaintiffs’

standing in this case. See generally Defs.’ Opp’n. Nevertheless, because Intervenor-Defendant

NRA and Amicus Curiae SCI have raised various standing arguments (albeit none that are

meritorious), the Court shall briefly consider Plaintiffs’ standing.

The elements of standing are well-established. A plaintiff must show: (1) that it has

suffered an injury in fact, which is the invasion of a legally protected interest that is (a) concrete

and particularized and (b) actual or imminent, not conjectural or hypothetical; (2) that there is a

causal connection between the injury and the conduct at issue, such that the injury is fairly

traceable to the challenged act; and (3) that it is likely, as opposed to speculative, that the injury

will be redressed by a favorable decision. Lujan v. Defenders of Wildlife, 504 U.S. 555, 560-61

(1992). To establish prudential standing, a plaintiff must show “only that its ‘interest is arguably

one regulated or protected by the statutory provision at issue.’” Safe Extensions, Inc. v. Fed.

Aviation Admin., 509 F.3d 593, 600 (D.C. Cir. 2007) (internal quotation marks omitted).

Plaintiffs bear the burden of demonstrating that they have standing. See Lujan, 504 U.S.

at 561 (“The party invoking federal jurisdiction bears the burden of establishing [the] elements

[of standing].”). Plaintiffs need not show that each plaintiff has standing to assert every claim;

rather, “if constitutional and prudential standing can be shown for at least one plaintiff, [the

court] need not consider the standing of the other plaintiffs to raise that claim.” Mountain States

40
Legal Found. v. Glickman, 92 F.3d 1228, 1221 (D.C. Cir. 1996) (citing Watt v. Energy Action

Educ. Found., 454 U.S. 151, 160 (1981)).

An organization (such as Plaintiffs) may assert standing on behalf of its members when

“(a) its members would otherwise have standing to sue in their own right; (b) the interests it

seeks to protect are germane to the organization’s purpose; and (c) neither the claim asserted nor

the relief requested requires the participation of individual members in the lawsuit.” Hunt v.

Wash. Apple Adver. Comm’n, 432 U.S. 333, 343 (1977). Even if an organization does not have

members, it may still have organizational standing if it “is the functional equivalent of a

traditional membership organization.” Fund Democracy LLC v. SEC, 278 F.3d 21, 25 (D.C. Cir.

2002) (citing Hunt, 432 U.S. at 343-45). In such instances, a court must assess whether it

functions like a “traditional membership organization” by examining whether (1) it serves a

specialized segment of the community; (2) represents individuals that have all the “indicia of

membership” including (i) electing the entity’s leadership, (ii) serving in the entity, and (iii)

financing the entity’s activities; and (3) has fortunes that are tied closely to that of its

constituency. Id.

In this case, both NPCA and Brady have easily met their burden to show organizational

standing. Members of NPCA visit and enjoy national parks and wildlife refuges on a frequent

basis. Pls.’ Mot., Ex. A ¶ 3 (Decl. of T. Kiernan). As a direct result of the Final Rule, NPCA’s

members assert that they fear both for their personal safety as well as for the environment they

enjoy in national parks and wildlife refuges. Id. ¶ 7. Brady’s members visit and enjoy national

parks and wildlife refuges on a frequent basis. See, e.g., Brady Reply, Ex. G ¶ 3 (Decl. of S.

Verge). As a direct result of the Final Rule, Brady’s members assert that they feel less safe and

41
that the Final Rule has reduced their “opportunities to pursue recreational, aesthetic, and leisure

activities in national park areas.” Id. ¶ 2. These injuries are traceable to the Final Rule, which

lifted restrictions on the possession of concealed, loaded, and operable firearms, and are

redressable if the restrictions are restored. See, e.g., id. ¶ 4 (Brady member indicating that if the

Final Rule is vacated or changed, she “will once again feel safe in and fully enjoy national

parks”). Based on the foregoing, the Court finds that NPCA and Brady have met their burden to

demonstrate standing in this case. Cf. Nat’l Parks Conservation Ass’n v. Manson, 414 F.3d 1, 4

(D.C. Cir. 2005) (“As an organization dedicated to the conversation of, and whose members

make use of, public lands, [NPCA] suffers a cognizable injury from environmental damage to

those lands.”).

The NRA’s standing argument is that Brady has failed to set forth a cognizable theory of

“organizational standing” because its members “do not have the indicia of membership found

significant by the [Supreme] Court” in Hunt v. Washington Apple Advertising Commission, 432

U.S. 333 (1977). See NRA Opp’n at 21-22. In particular, the NRA asserts that Brady’s members

do not have the right to elect their governing body, its articles of incorporation do not require that

its directors be members, and Brady’s articles of incorporation do not require the purported

members to pay dues. Id. at 22.

The NRA’s standing argument is based upon a flawed reading of Hunt and specific facts

concerning Brady. The inquiry into the “indicia of membership” that occupies the NRA’s focus

is necessary only when an organization is not a “traditional membership organization.” See

Gettman v. High Times Magazine, 290 F.3d 430, 435 (D.C. Cir. 2002) (“‘[i]n determining

whether an organization that has no members in the traditional sense may nonetheless assert

42
associational standing, the question is whether the organization is the functional equivalent of a

traditional membership organization’”) (quoting Fund Democracy, 278 F.3d at 23) (emphasis

added); Fund Democracy, 278 F.3d at 26 (distinguishing between “members or any equivalent

affiliates”). Thus, the D.C. Circuit has explained that the plaintiff organization in Hunt, on

which the NRA predicates its argument, “concerned an organization that premised standing upon

the claims of non-members.” Am. Legal Found. v. Fed. Commc’n Comm’n, 808 F.2d 84, 89

(D.C. Cir. 1987) (emphasis added).

In this case, Brady submitted a declaration from the President of the organization stating

that “[t]he Brady Campaign is the nation’s largest national, non-partisan, grassroots membership

organization leading the fight to prevent gun violence . . . The Brady Campaign has members in

every state of the country . . .” Brady Mot., Ex. G ¶ 2 (Decl. of P. Helmke). Brady also

submitted declarations from several of its members describing the effect that the Final Rule will

have on them. See Brady Reply, Exs. G-P (multiple declarations submitted by Brady members).

Brady also submitted a copy of its Articles of Incorporation which state that “[t]he Corporation

[Brady] shall have members. The members shall have voting rights as prescribed in the By-

Laws.” Id., Ex. E at 3 (1/16/74 Articles of Incorporation). Accordingly, Brady has sufficiently

established its existence as a membership organization, and the Court rejects as flawed the

NRA’s assertion that it has failed to establish organizational standing.18

18
The standing arguments raised by Amicus Curiae SCI do not require extended analysis,
as they are almost entirely based on its view of the Final Rule’s environmental impacts (or lack
thereof), thereby implicating the precise merits-based question associated with Plaintiffs’ claims.
The Court declines to resolve the merits of Plaintiffs’ claims in the context of standing.
“[T]hough the trial court may rule on disputed jurisdictional facts at any time, if they are
inextricably intertwined with the merits of the case it should usually defer its jurisdictional
decision until the merits are heard.” Herbert v. Nat’l Acad. of Sciences, 974 F.2d 192, 198 (D.C.

 IV. CONCLUSION

For the reasons set forth above, the Court shall GRANT Plaintiffs’ Motion for a

Preliminary Injunction. Defendants shall be enjoined from implementing or enforcing the Final

Rule published in the Federal Register on December 10, 2008, that amends 36 C.F.R. § 2.4 and

50 C.F.R. § 27.42 (located at 73 Fed. Reg. 74,966-74,972), to allow persons to “possess, carry,

and transport concealed, loaded, and operable firearms within a [national park or national

wildlife refuge] in accordance with the laws of the state in which the [national park or national

wildlife refuge], or that portion thereof, is located, except as otherwise prohibited by applicable

Federal law.” An appropriate Order accompanies this Memorandum Opinion.
