Abstract

The Bureau of Alcohol, Tobacco, Firearms, and Explosives ("ATF") is amending Department of Justice ("Department") regulations on reporting explosive materials storage. Currently, any person who stores explosive materials subject to ATF's explosives regulations must notify the authority having jurisdiction for fire safety in that locality when they begin storing explosives at that site. This rule adds a requirement to also submit written notices every 12 months thereafter and when the person ceases storing explosives at that location and to retain copies of the notices for five years. These changes are intended to increase public safety, particularly for first responders.

Annual Notices on Explosive Materials Storage Facilities to Local 
Fire Authority

AGENCY: Bureau of Alcohol, Tobacco, Firearms, and Explosives, 
Department of Justice.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Bureau of Alcohol, Tobacco, Firearms, and Explosives 
(``ATF'') is amending Department of Justice (``Department'') 
regulations on reporting explosive materials storage. Currently, any 
person who stores explosive materials subject to ATF's explosives 
regulations must notify the authority having jurisdiction for fire 
safety in that locality when they begin storing explosives at that 
site. This rule adds a requirement to also submit written notices every 
12 months thereafter and when the person ceases storing explosives at 
that location and to retain copies of the notices for five years. These 
changes are intended to increase public safety, particularly for first 
responders.

DATES: This rule is effective October 26, 2026.

SUPPLEMENTARY INFORMATION:

I. Background

    Title XI of the Organized Crime Control Act of 1970 (``OCCA''), 
Public Law 91-452, 84 Stat. 922 (1970) added 18 U.S.C. chapter 40 
(Importation, Manufacture, Distribution, and Storage of Explosive 
Materials) to part I, on crimes. One of the stated purposes for title 
XI was to reduce the ``hazard to persons and property arising from 
misuse and unsafe or insecure storage of explosive materials.'' Public 
Law 91-452, sec. 1101, 84 Stat. at 952. The Attorney General is 
responsible for implementing title XI. See 18 U.S.C. 847. The Attorney 
General has delegated that responsibility to the Director of ATF 
(``Director''), subject to the direction of the Attorney General and 
the Deputy Attorney General.\1\ See 28 U.S.C. 599A(b)(1), (c)(1); 28 
CFR 0.130(a)(1)-(2); Treas. Order No. 221(2)(a), (d), 37 FR 11696-97 
(June 10, 1972). Regulations in 27 CFR part 555 implement title XI.
---------------------------------------------------------------------------

    \1\ In Attorney General Order Number 6353-2025, the Attorney 
General delegated authority to the Director to issue regulations 
pertaining to matters within ATF's jurisdiction, including under 
OCCA, the National Firearms Act, and the Gun Control Act. ATF's 
jurisdiction also includes the Arms Export Control Act and the 
Contraband Cigarette Trafficking Act.
---------------------------------------------------------------------------

    On August 24, 1998, ATF published in the Federal Register a final 
rule to implement a storage notification requirement for manufacturers 
and other persons who store explosives.\2\ ATF amended the regulations 
in 27 CFR part 55 (now part 555) \3\ to require that any person who 
begins storing explosive materials must notify the authority having 
jurisdiction for fire safety in the locality in which the explosive 
materials are being stored of the storage type, magazine capacity, and 
location of each site where such explosives are stored (the structure 
storing the explosive materials is hereinafter referred to as a 
``magazine'').\4\ The 1998 final rule was issued in response to 
numerous deaths and injuries sustained by emergency response personnel 
responding to fires and other emergencies at sites where explosives 
were stored without the knowledge of state and local officials.\5\
---------------------------------------------------------------------------

    \2\ Commerce in Explosives, final rule, RIN 1512-AB55, 63 FR 
44999 (August 24, 1998). In this rule, ATF amended the regulations 
in 27 CFR part 55 (now part 555) to require that any person who 
begins storing explosive materials must notify the authority having 
jurisdiction for fire safety in the locality in which the explosive 
materials are being stored of the storage type, magazine capacity, 
and location of each site where such explosives are stored. The rule 
was issued in response to numerous deaths and injuries sustained by 
emergency response personnel responding to fires and other 
emergencies at sites where explosives were stored without the 
knowledge of state and local officials. See Commerce in Explosives 
proposed rule, RIN 1545-AU09, 61 FR 53688 (Oct. 15, 1996).
    \3\ On January 24, 2003, ATF issued a final rule titled 
``Reorganization of Title 27, Code of Federal Regulations,'' which, 
among other things, removed part 55 from chapter I and recodified it 
as part 555 in the new chapter II. 68 FR 3744.
    \4\ Although the reporting requirement is per site or location, 
ATF defines ``magazine'' as ``Any building or structure, other than 
an explosives manufacturing building, used for storage of explosive 
materials.'' See 27 CFR 555.11. As a result, for easier reference, 
ATF is referring in this rule to all structures storing explosive 
materials as ``magazines.''

    ATF is concerned with the safety of emergency response personnel

[[Page 60804]]

responding to fires on sites where explosives are stored, and the 
safety of the public around such areas. It is important that first 
responders are aware of explosives storage when responding to a fire 
site so they can take action that accounts for the explosives. For 
example, firefighters and other fire safety officials generally do not 
attempt to fight a fire that involves explosive materials because of 
the significant danger an explosion poses to such responders. If they 
know of the existence of explosives in such close proximity to a fire 
before they arrive, officials often evacuate the facility and the 
surrounding area to ensure the safety of the first responders and the 
public, rather than fighting the fire as they would if explosives were 
not present.\6\
---------------------------------------------------------------------------

    \6\ See, e.g., Centers for Disease Control and Prevention, 
National Institute for Occupational Safety and Health (NIOSH) Report 
# F2013-11, Recommendation #1, pg. 23 (finding that a detailed pre-
plan that included thorough assessment of characteristics of 
material stored at high-risk facility could have identified 
potential for risks of fighting the fire, including explosion) and 
Appendix Three, pg. 48 (recommending that owners of storage 
facilities coordinate with local first responders as part of a site 
emergency plan, and that firefighters, before responding to a fire 
involving explosive materials, know the quantity, storage types, and 
locations of explosive materials in their communities and include in 
their procedures a decision process to determine whether such a fire 
should be fought or focus should be on moving themselves to safe 
location and evacuating nearby residents); National Fire Protection

members are excessive, activities shall be limited to defensive 
operations); Institute of Makers of Explosives (IME) guidance Safety 
and Security Guidelines for Ammonium Nitrate (recommending that when 
any oxidizer fire is involved, firefighters should avoid trying to

hazardous materials, have an up-to-date pre-incident plan including 
information on the materials' storage location and quantities, and 
first consider whether the fire can be fought or if the explosive 
material makes the approach too hazardous, at which point move to a 
safe location and focus on evacuating).
---------------------------------------------------------------------------

    The regulation at 27 CFR 555.201(f) requires that all persons 
storing explosives report certain information when they begin storing 
the explosive materials but does not specifically require subsequent 
reporting that might reflect changes in storage types and magazine 
capacity. Executive Order 13650, ``Improving Chemical Facility Safety 
and Security,'' signed August 1, 2013, discussed the need to implement 
safety measures for handling and storing chemicals, to include 
explosive materials. In addition, it established a working group co-
chaired by the heads of the Environmental Protection Agency (``EPA'') 
and the Departments of Labor and Homeland Security. Membership included 
the heads of the Departments of Justice, Agriculture, and 
Transportation, who would work with the co-chairs to carry out the 
responsibilities of the executive order. A final report, submitted by 
the Chemical Facility Safety and Security Working Group to the 
President in May 2014, noted that ATF would work closely with 
explosives industry associations to develop best practices, procedures, 
or regulations to improve communication with fire authorities, 
including more frequent notification of significant changes to storage 
facilities.\7\

---------------------------------------------------------------------------

    Explosives industry association representatives provided input on 
these topics during discussions with ATF conducted in connection with 
implementing Executive Order 13650. These representatives recommended 
that ATF amend the notice requirement in Sec.  555.201(f) to require 
annual notices.\8\ They stated that this would increase communication 
between industry members and their local emergency responders, mitigate 
the negative effects of turnover in the emergency response community, 
and increase training opportunities for the local responders. Based on 
additional discussions with industry representatives over time, the 
Department and ATF consider annual notices necessary as a means to 
increase public safety by fostering more communication between persons 
who store explosives and fire authorities, increasing and updating 
first responder knowledge about explosives stored in the area, and 
enabling them to better plan and respond to fires that occur in 
locations where explosives are stored.

II. Notice of Proposed Rulemaking

    On August 23, 2023, the Department published in the Federal 
Register a notice of proposed rulemaking (``NPRM'') entitled ``Annual 
Reporting of Explosive Materials Storage Facilities to the Local Fire 
Authority,'' 88 FR 57370, proposing changes to 27 CFR 555.201(f). The 
comment period closed November 21, 2023.
    The Department issued this NPRM as a result of ATF's consultations 
with explosives industry associations. The proposed rule explained that 
ATF believes that a requirement for annual notices would: (a) lead to 
more frequent contact between persons storing explosive materials and 
local fire authorities; (b) ensure that explosives storage information 
would be provided in a timely manner to new first responder staff 
members; and (c) reinforce the importance of the information to fire 
response organizations. The proposed rule expressed ATF's belief that a 
recurring 12-month notice timeframe would best balance the need for 
these results against the burden of more frequent notices.
    For these reasons, the Department proposed to amend 27 CFR 
555.201(f) to require that, every 12 months after initial notification, 
any person who is storing explosive materials must notify the authority 
having jurisdiction for fire safety (in the locality in which the 
explosive materials are being stored) that they are continuing to store 
explosive materials, and to notify the same authority when the person 
ceases storing explosive materials at that location. The proposed 
amendment further required that the notice must include the type of 
explosives, magazine capacity, and location of each site where such 
materials are stored. In addition, the NPRM proposed a requirement that 
the person providing these notices must retain a copy of each notice 
for five years from the date of the notice, and make these records 
available for ATF inspection at all reasonable times.

III. Analysis of Comments and Agency Responses

    In response to the proposed rule, ATF received approximately 500 
comments. The commenters included industry associations, firearms 
owners, state marshals, county officials, firefighters, hazardous 
material specialists, and the public.

A. Supporting Comments

1. Enhances Safety
Comments Received
    Several commenters expressed support for the proposed rule because 
they felt explosives in a facility represent an obvious safety issue 
for the public and those who put their lives on the line every day, 
such as first

[[Page 60805]]

responders. Some of these commenters focused on safety for first 
responders. For example, one commenter stated anything that helps first 
responders come home alive at the end of the day requires the utmost 
attention. Another commenter added that this proposed rule would 
enhance the safety and security of first responders through increased 
awareness of where explosive materials are located.
    Other commenters focused on public safety or safety to both public 
and first responders. For example, one commenter emphasized that 
``having updated information on the locations and amounts of explosives 
stored in the jurisdiction will provide transparency and facilitate 
better preparation in advance of an incident.'' Another commenter 
similarly expressed that ensuring fire authorities are aware of 
location, type, and quantity of explosive materials in their 
jurisdiction would enhance not only their safety but that of the public 
as well. They also stated the proposed rule would help ATF enforce the 
federal explosives laws and regulations more effectively. Another 
commenter also added that the safety benefits of this rule would 
outweigh the costs and burdens of the notice requirement.
ATF Response
    ATF agrees the rule would increase safety for first responders, who 
might be required to respond to incidents at sites where explosives are 
stored, as well as the public generally. First responders would be 
better prepared to respond to incidents at sites where explosives are 
stored if they receive annual notification regarding explosives being 
stored at a given location. The federal explosives regulations 
currently require all persons who store explosive materials subject to 
ATF's explosives regulations in 27 CFR part 555 to notify the authority 
having jurisdiction for fire safety in the locality in which the person 
is storing explosive materials of the type of explosive materials, the 
magazine capacity, and the location of each site where they are storing 
explosive materials. The existing regulations require this notification 
when the person begins storing explosives at a site. The rule would add 
a requirement that the person storing explosive materials must also 
notify the same authority of the same information (updated as 
applicable) every 12 months thereafter and when they cease storing 
explosive materials.
2. Increases Communication With Emergency Responders and Aids Emergency 
Responder Risk Assessment
Comments Received
    Some commenters felt the proposed rule would aid law enforcement 
and communities in preparing for and adapting to potential explosives 
issues by providing important information and enhancing communications. 
For example, one industry association stated that the notice 
requirement would ensure: (1) information is accurate; (2) current 
information is available to local responders as well as the community; 
and (3) local responders could make adjustments to local response plans 
based on this information, if needed. Another commenter suggested the 
proposed notice requirements should become a requirement to inform the 
local fire department if explosives are in a particular location. One 
commenter added that this rule change could help the industry educate 
first responders about the risks and dangers of responding to fires 
that involve explosives and assist in ``familiarizing responders with 
the facilities' risk assessments and emergency response and evacuation 
plans.'' They also added that annual notices would increase 
communication and provide transparency among industry members and local 
responders in their jurisdiction. A final commenter stated that the 
rule would not impose any new requirements but only clarify and 
streamline the notification process.
ATF Response
    ATF agrees that increased communication between persons storing 
explosive materials and fire-safety authorities would better prepare 
first responders in the event of an incident at a site where covered 
explosive materials are stored. Knowing about the type of explosives, 
capacity of any magazine(s) at a site, and the location of each site 
where explosives are stored is vital for first responders to prepare an 
effective plan when responding to an emergency at a given location. As 
stated previously, all persons are already required to report 
explosives storage type, magazine, and location information when they 
begin storing explosive materials covered by ATF regulations. The rule 
would not change that requirement but would add a requirement that such 
persons must then submit notices with the same information (updated as 
applicable) every 12 months thereafter and when they cease storing 
explosive materials. This would ensure emergency responders have 
current and accurate information regarding the presence, and potential 
amount (magazine capacity), of explosive materials if called to respond 
to a location where covered explosives are being stored.
3. Reasonable Notice Requirements
Comments Received
    In addition to expressing support for the proposed notice 
requirement, some commenters also stated that the record-keeping 
requirement was supportable because it did not impose an undue burden 
on industry. For example, one commenter emphasized that annual notices 
as proposed in the rule would not be an inconvenience. They also stated 
that the proposed rule would not be an invasion of privacy because the 
notices would be sent only to local authorities, rather than to a 
centralized national organization. Another commenter did not believe 
the proposed changes would infringe on Constitutional rights because it 
is already a requirement to notify local officials of explosives 
storage in the area and this rule just adds a requirement to update 
that notice periodically. This commenter also said the proposed rule is 
not burdensome because it just improves the notice process of explosive 
materials storage. Another commenter agreed that annual notices will 
reinforce the importance of the information to local responders. And 
one commenter indicated that 30 minutes as an estimate of the time it 
would take to notify annually is a reasonable time and would not be a 
burden.
ATF Response
    ATF agrees that the rule would not place an undue burden on 
industry. Most explosives industry members established a system to 
notify their local fire authority under the current regulations when 
they began storing explosives at a given site, and a system to notify 
their local fire authority in the event of an explosives incident. The 
subsequent annual notices could be in the same format as the first one, 
and if the person has made no changes that year to the existing 
explosives storage, the next annual notice would not need to change. If 
there is a change to the explosives storage, making an update to the 
previous notice would require only minimal effort.
    The regulations currently require that the notification include the 
storage type, magazine capacity, and location of each site where such 
materials are stored. The rule would not impose any new additions to 
what is already included in the notice requirement. The only change 
would be the annual nature of the notice

[[Page 60806]]

requirement. As a result, notifying annually would not require new 
processes or more than minimal additional work. Once the person storing 
covered explosives notifies the locality in writing, they need only 
retain a copy (which may be in digital form) of that notice for five 
years. ATF therefore does not believe the additional requirement as 
stated in the rule would impose a significant burden on the explosives 
industry. ATF does believe, however, that it would significantly 
increase the safety to first responders who are responsible for 
responding to incidents at sites where explosives are stored.
    ATF also agrees that this rule does not infringe on any 
Constitutional rights for the reasons discussed in section III.B.3 of 
this preamble.

B. Opposing Comments

1. Rule Is Unnecessary
Comments Received
    Some commenters disagreed with the proposed rule and thought the 
Department should not finalize it because they considered it 
unnecessary, invalid, not factual or reasonable, or even foolish, 
ridiculous, or recklessly irresponsible, without providing further 
explanation. A few commenters stated that not only did they think the 
Department was imposing an unnecessary and unjustified regulation on 
the public, they thought the proposed rule also did not provide a 
benefit to the public.
    A few commenters provided additional explanation on the subject. 
One commenter stated that there has been no evidence that ``ordinary 
citizens'' possessing explosive materials present a widespread problem. 
A couple of other commenters stated that the proposed rule was 
confusing and needed to clarify how notifying authorities about 
magazine locations would help local fire departments. Another commenter 
remarked that first responders need to know what is being stored only 
during an emergency. One commenter who thought the proposed rule was 
unnecessary said there is no guarantee that the notice process would be 
accurate. A couple of other commenters questioned ATF's evidence 
supporting the need for this rule and stated that there were no 
problems with the current situation, so there is no need for a rule.
    One commenter believed the proposed rule was unnecessary as, the 
commenter stated, there are already mechanisms in place to keep first 
responders safe when responding to major residential or structural 
fires. Other commenters elaborated on this topic by specifying that the 
proposed rule would be duplicative of other, already-existing, 
government agency or organization requirements, such as EPA Tier II 
Inventory Form, Occupational Safety and Health Administration's 
(``OSHA's'') ``right to know'' requirements, and hazmat placards under 
Department of Transportation (``DOT''), the International Fire Code, or 
the National Fire Protection Association's (``NFPA'') codes and 
standards. Similarly, a couple of other commenters added that hazmat 
permits already provide adequate notification to fire responders about 
the presence of dangerous materials.
    Some commenters considered the proposed rule to be unnecessary or 
inappropriate due to concerns about the type of explosives they believe 
would have to be reported, and tracking or registry aspects they 
believed were involved in the notice requirements. For example, 
regarding the type of explosives, two commenters stated that gunpowder 
up to 50 pounds has never had a registration requirement, and there is 
no need for one now. Another added that the proposed rule was 
unnecessary because black powder notice requirements are already 
mandated by federal and state regulations. By contrast, a third 
commenter said they supported the proposed rule because it applied only 
to certain explosives, such as dynamite or similar explosives used for 
construction, demolition, and mining.
    On the subject of tracking or creating a registry, one commenter 
stated that ATF failed to provide any evidence that a national database 
is a necessary or an appropriate way to maintain a list that is useful 
to volunteer fire departments, whereas another commenter stated that 
they considered the changes in the proposed rule to be crucial because 
they would be a form of keeping track of weapons in our country.
ATF Response
    ATF agrees that the rule should not apply to all materials that can 
explode because some of them (including small amounts of gunpowder) are 
already exempt from ATF's explosives regulations. While the rule 
requires all persons storing explosives to submit notices about those 
explosives annually, that requirement would apply only to explosive 
materials that are subject to ATF's explosives regulations in 27 CFR 
part 555. The rule would not apply to explosive materials that are 
specifically exempt from ATF's explosives regulations, such as consumer 
fireworks, small-arms ammunition, and components of small-arms 
ammunition (e.g. primers, propellant, etc.). See 18 U.S.C. 845(a); 27 
CFR 555.141. In addition, the exempt explosive materials include 
commercially manufactured black powder in quantities not exceeding 50 
pounds (as well as percussion caps, safety and pyrotechnic fuses, 
quills, quick and slow matches, and friction primers) intended to be 
used solely for sporting, recreational, or cultural purposes in antique 
firearms as defined in 18 U.S.C. 921(a)(16), or in antique devices 
exempted from the term ``destructive device'' in 18 U.S.C. 921(a)(4). 
See 18 U.S.C. 845(a) and the 2025 Annual List of Explosive Materials, 
90 FR 25077 (June 13, 2025). See also ATF's response in section III.B.7 
of this preamble.
    Therefore, the annual notice requirement applies to the same people 
who are already required to submit a notice when they begin storing 
explosives covered by ATF's regulations.
    ATF disagrees that the rule is unnecessary. The rule is designed to 
protect the safety of emergency response personnel responding to fires 
on sites where explosives are stored. It is important that first 
responders are aware of explosives storage prior to responding to a 
fire site so they can take remedial action that accounts for the 
explosives. While the rule covers only the types of explosive materials 
that are regulated by ATF, those materials pose a risk to emergency 
response personnel, including when possessed by unlicensed ``ordinary 
citizens.'' The rule therefore applies to all ``persons,'' as defined 
by 18 U.S.C. 841 and 27 CFR 555.11, not just federal explosives 
licensees/permittees. Federal regulations generally require that a 
person have a license/permit to obtain explosive materials covered by 
ATF regulations, but all persons, even those without a license/permit, 
must store explosives in conformity with part 555. 18 U.S.C. 842(j), 27 
CFR 555.26 and 555.29. A person with a license/permit could acquire 
explosives regulated under part 555, subsequently not renew that 
license/permit, and legally retain those explosive materials. This 
would result in an ``ordinary citizen'' who is not a licensee/permittee 
retaining explosives inventory of a type regulated by ATF that could 
pose a risk to the public and emergency response personnel. Federal law 
and regulations currently require any person possessing federally 
regulated explosive materials to store those explosives in accordance 
with part 555, which includes a requirement to report those explosives 
to local fire authorities. The rule merely

[[Page 60807]]

requires any person storing such explosives to notify local authorities 
of such storage every 12 months and when they cease storing such 
materials. Again, the rule does not cover explosives not regulated by 
ATF pursuant to part 555.
    Additionally, in response to the comments that stated the rule is 
unnecessary because ATF provided no evidence that a national database 
was needed, or that asserted the notice requirement involves tracking 
or registry aspects, ATF notes that it is not proposing a national 
database or registry of explosive materials stored by individuals. In 
fact, the rule requires only that the individual provide notification 
of the type of explosive, the magazine capacity, and the location of 
the magazine to their local fire safety authority, not to ATF. The 
notification would not require persons storing explosive materials to 
report on specific amounts or changes in the amounts of explosives 
stored; only the magazine capacity, which alerts first responders to 
the potential danger for which they should prepare and dictates the 
distance the magazine must be from other structures, etc., for safety 
purposes.
    Licensees/permittees already inform ATF of magazine capacity and 
their magazines are inspected periodically by ATF to ensure they meet 
distance and other safety requirements. This rule does not extend that 
oversight; it simply requires persons to report magazine capacity to 
local fire authorities, who then can prepare to respond and who would 
know only the magazine capacity for magazines in their jurisdiction. 
Nor would local fire authorities submit these notices to ATF. Rather, 
the person making the notification would have to retain a copy of the 
written notice (which may be in digital form) for five years. Copies 
retained by licensees/permittees would be subject to inspection by ATF, 
while copies retained by non-licensees/permittees would verify 
compliance with the storage provisions of part 555.
    ATF does not believe that the rule would duplicate existing 
government agency requirements, including those provided as examples by 
commenters. ATF is not aware of any other existing federal requirement 
to notify local fire authorities about explosives storage locations. In 
addition, ATF is the primary federal agency responsible for ensuring 
that explosive materials are safely and securely stored. ATF believes 
that requiring annual notification to the local fire authority will 
benefit public safety by ensuring that first responders are better 
prepared to respond to incidents at explosives storage sites.
2. Scope of Authority
Comments Received
    Many commenters described the proposed rule as an overreach of 
ATF's authority. Commenters stating that the proposed rule was an 
overreach articulated different reasons for their belief. Several 
commenters characterized the proposed rule as an attempt to circumvent 
the rule of law and the congressional lawmaking process. For example, 
many commenters stated that ATF does not have authority to make laws; 
only Congress can, and some commenters believed the rule and its 
changes to the law had to be passed by an act of Congress. Some 
commenters stated that the proposed rule overstepped the Department's 
authority by bypassing checks and balances and introducing laws. In a 
similar vein, other commenters asked what authority or law gives ATF 
the ability to make rules that end up having the weight of law. A 
couple of commenters implored ATF to ``consider the implications of yet 
another revision of law done outside the purview of Congress. While 
this proposal sounds exceedingly logical on the surface, I am concerned 
about the possibility of future overreach by [ATF] . . . . Today's 
`common-sense' rules become tomorrow's `loopholes' that need to be 
closed, and I believe this is a wide-open back door to future 
restrictions.'' Two commenters cited to West Virginia v. Environmental 
Protection Agency, 597 U.S. 697 (2022). One of them stated that, 
according to the case, an act of Congress is needed to change how 
powders have been recorded. The other commenter referred to the case in 
support of the contention that ATF must, and can only, enforce the laws 
that Congress creates.
    A few other commenters more generally stated that the proposed rule 
was an overreach into a realm that should be reserved to localities and 
States. Another believed the proposed rule raised several concerns that 
impact individuals on their own private property in ways that were 
overreaching and heavy-handed. And another commenter believed the 
overreach was predicated on assumptions that were not true, although 
they did not state what those assumptions were.
    A small number of commenters described the proposed rule as 
arbitrary. One commenter opposed the rule based on the Administrative 
Procedure Act, stating the proposed rule did not fall within ATF's 
mandated purview and burdened intrastate agencies, without further 
clarification.
    Multiple commenters stated the proposed rule should not be 
finalized because it would be challenged in court. Other commenters 
stated that rulemaking procedures from ATF have repeatedly been struck 
down by federal courts as an overreach of authority, so the Department 
should not proceed with this rule; and it would be a ``moot point.'' 
Other commenters expressed the opinion that the rule would do nothing 
but create expensive federal lawsuits and would be a waste of 
government resources and taxpayer dollars. Another commenter stated 
that, instead of focusing on creating new rules that are likely to be 
challenged and struck down in federal court, it would be more prudent 
for ATF to concentrate its efforts on enforcing existing laws and 
regulations. By directing its attention toward individuals who are 
breaking the current laws, the commenter added, ATF could better ensure 
public safety and uphold the principles of justice.
ATF Response
    In response to all the comments on this topic, which in various 
ways indicate an underlying perception that the rule would overreach 
and invade privacy because its scope would cover powder and involve 
invading peoples' homes, ATF notes that the rule applies only to 
explosive materials that are subject to ATF's explosives storage 
regulations at 27 CFR part 555, subpart K, which sets out explosives 
storage requirements. It does not apply to those explosive materials 
that are specifically exempt from ATF's regulations, such as consumer 
fireworks, small-arms ammunition, components of small-arms ammunition 
(e.g., primers, propellants), and commercially manufactured black 
powder in quantities not exceeding 50 pounds (as well as percussion 
caps, safety and pyrotechnic fuses, quills, quick and slow matches, and 
friction primers) intended to be used solely for sporting, 
recreational, or cultural purposes in antique firearms as defined in 18 
U.S.C. 921(a)(16), or in antique devices exempted from the term 
``destructive device'' in 18 U.S.C. 921(a)(4). See 18 U.S.C. 845; 27 
CFR 555.141.
    ATF's explosives storage regulations already require that persons 
storing covered explosive materials must report the stated information 
to authorities having local jurisdiction for fire safety when the 
person begins storing covered explosive materials. The rule would 
simply require annual notices thereafter. Nothing else, including the 
kinds of explosive materials subject to this requirement, would change. 
ATF believes that the rule would provide

[[Page 60808]]

first responders with information vital to ensure their safety should 
an incident occur at an explosives storage site.
    West Virginia v. Environmental Protection Agency is inapplicable 
because there is no ``extraordinary grant of regulatory authority.'' 
West Virginia involved the ``major questions doctrine,'' or ``cases in 
which the `history and breadth of the authority that [the agency] has 
asserted' and the `economic and political significance' of that 
assertion, provide a `reason to hesitate before concluding that 
Congress' meant to confer such authority.'' Id. at 721. The Court found 
that EPA's interpretation of a statute would ``substantially 
restructure the American energy market.'' Id. at 724. Having the same 
regulated community report to their local fire safety authority the 
same information they provide upon initial storage every 12 months and 
when they cease storing the materials does not approach a ``major 
question'' or a ``substantial[ ] restructure'' of anything.
    ATF disagrees that it lacks the legal authority to promulgate this 
rule as proposed and finalized. 18 U.S.C. 847 authorizes the Attorney 
General to prescribe rules and regulations that are reasonably 
necessary to carry out the provisions of Title XI of the OCCA, 18 
U.S.C. chapter 40. Congress enacted chapter 40, which tasks the 
Attorney General with the responsibility, delegated to ATF, for 
investigating and enforcing criminal and regulatory violations of 
federal explosives laws. 28 U.S.C. 599A; 28 CFR 0.130(a)(1). The OCCA, 
as amended by the Safe Explosives Act (``SEA''), regulates explosives 
as defined, including safeguards for storing such explosives. As such, 
the regulations set forth requirements that implement the federal 
explosives laws, which include storing explosive materials regulated by 
the agency. Further, the rule is directly within the agency's purview 
as delegated by Congress and the Attorney General. Federal law makes it 
unlawful for any person to store explosive materials in a manner not in 
conformity with regulations promulgated by the Attorney General under 
18 U.S.C. 842(j). This provision also states, in relevant part, that 
``[i]n promulgating such regulations, the Attorney General shall take 
into consideration the class, type, and quantity of explosive materials 
to be stored, as well as the standards of safety and security 
recognized in the explosives industry.'' The rule establishes certain 
standards that are necessary for the safety and security of stored 
explosive materials, as recommended by explosives industry members, and 
is therefore consistent with the Department's and ATF's statutory 
authority to implement section 842(j). It is also consistent with the 
legislative purpose of the OCCA, which ``is to protect interstate and 
foreign commerce against interference and interruption by reducing the 
hazard to persons and property arising from misuse and unsafe or 
insecure storage of explosive materials.'' OCCA sec. 1101.
3. Rule Is Unconstitutional
    A significant number of commenters felt that the proposed rule was 
unconstitutional, illegal, or infringed upon or violated individual 
rights. The sections below discuss the specific parts of the 
Constitution commenters believed the rule violated.
a. Violates the Second Amendment
Comments Received
    Numerous commenters stated the proposed rule would infringe on the 
Second Amendment's right to bear arms, with several describing it as a 
``blatant'' violation of the Second Amendment or stating that it would 
put a ``chokehold'' on their rights. One commenter stated that the 
proposed rule would have too broad of an application because it was not 
limited to businesses and individuals who hold explosive licenses, and 
it was therefore a dystopian abandonment of the Second Amendment. Many 
commenters likened the proposed rule to actions taken by British 
soldiers that the commenters stated initiated the American 
Revolutionary War by attempting to control possession of gunpowder. One 
commenter stated that the proposed rule was a direct attack on Second 
Amendment rights and had nothing to do with public safety. Another 
commenter stated that anyone violating the proposed rule would likely 
be stripped of their Second Amendment rights.
    Additionally, many commenters supported the contention that the 
proposed rule violated the Second Amendment by pointing to Supreme 
Court cases, particularly New York State Rifle and Pistol Association 
v. Bruen, 597 U.S. 1 (2022), because, they stated, the proposed rule 
did not meet the text, history, and tradition test established by that 
case. One commenter stated that, per their interpretation of the Bruen 
decision, all gun laws are unconstitutional.
    Several commenters raised more specific concerns that the rule 
infringed on their rights in relation to personal ammunition and 
firearms. Some of these commenters expressed concern because, they 
stated, the proposed rule applied to ammunition and gun powder, and 
they expressed that the proposed notice requirement would violate their 
Second Amendment protections. Another commenter stated that people have 
the right to make their own ammunition, and it has been that way since 
1791. Some commenters believed the proposed rule was a push to limit or 
take away the ability to own and fire guns or characterized it as 
illegal gun control, while another commenter asked if they would be 
subject to the proposed rule for having deer hunting ammunition, and 
another believed having a single bullet would require reporting to the 
fire department.
ATF Response
    ATF disagrees with commenters that the rule would regulate 
possessing or using firearms and ammunition or that it would violate 
the Second Amendment. The rule continues to apply only to explosive 
materials that are subject to ATF regulations. Contrary to concerns 
raised by commenters, that does not include firearms, commercially 
manufactured black powder in quantities not to exceed 50 pounds, or 
small-arms ammunition. In addition, the rule does not apply to or 
restrict possessing or using firearms and ammunition. See 18 U.S.C. 
845(a); 27 CFR 555.141.
    The Second Amendment recognizes an individual's right to keep and 
bear arms in common use for lawful purposes. District of Columbia v. 
Heller, 554 U.S. 570, 595, 625 (2008); Bruen, 597 U.S. at 17. The rule, 
however, does not regulate such arms. Heller, 554 U.S. at 625. Instead, 
it implements 18 U.S.C. 842(j), which requires any person to store 
explosive materials in a manner that conforms with regulations 
prescribed by the Attorney General. Federal law defines the term 
``explosive materials'' to mean ``explosives, blasting agents, and 
detonators,'' 18 U.S.C. 841(c), and the term ``explosives'' to mean, in 
relevant part, ``any chemical compound mixture, or device, the primary 
or common purpose of which is to function by explosion; the term 
includes, but is not limited to, dynamite and other high explosives, 
black powder, pellet powder, initiating explosives, detonators, safety 
fuses, squibs, detonating cord, igniter cord, and igniters,'' id. 
841(d).
    ATF also acknowledges that the Second Amendment right to keep and 
bear arms ``implicitly protect[s] those closely related acts necessary 
to'' the right's exercise. Luis v. United States, 578 U.S. 5, 26 (2016) 
(Thomas, J., concurring in judgment). But the rule

[[Page 60809]]

specifically exempts ``small arms ammunition and components of small 
arms ammunition,'' 27 CFR 555.141(a)(4), including ``cartridge cases, 
primers, bullets, or smokeless propellants designed for use in small 
arms, including percussion caps, and 3/32 inch and other external 
burning pyrotechnic hobby fuses,'' id. 555.11. The rule likewise 
exempts ``commercially manufactured black powder in quantities not to 
exceed 50 pounds, percussion caps, safety and pyrotechnic fuses, 
quills, quick and slow matches, and friction primers, if the black 
powder is intended to be used solely for sporting, recreational, or 
cultural purposes in antique firearms as defined in 18 U.S.C. 
921(a)(16), or antique devices as exempted from the term ``destructive 
device'' in 18 U.S.C. 921(a)(4). Id. 555.141(b).
    Even if the rule were interpreted as sweeping in some conduct 
covered by the Second Amendment's ancillary protections, the rule ``is 
consistent with the Nation's historical tradition of firearm 
regulation,'' Bruen, 597 U.S. at 684-85. Indeed, the nation has a long 
history of fire-safety laws regulating storing explosive materials such 
as gunpowder. See, e.g., Heller, 554 U.S. at 631-32. As a result, this 
rule does not violate the Second Amendment or interfere with people's 
ability to possess or use arms in common use for lawful purposes.
b. Violates the First, Fourth, and Fifth Amendments
Comments Received
    Some commenters specified that the proposed rule would constitute 
an infringement on privacy protected by the First Amendment but did not 
elaborate on these statements.
    A significant number of commenters opposed the proposed rule on 
grounds that it would circumvent and violate constitutional rights 
granted under the Fourth Amendment, constitute an intrusion, and would 
violate individual privacy. Multiple commenters expressed concerns that 
the proposed rule was clearly a means to search another's property 
without a warrant, and others that the rule would subject them to 
illegal search and seizure, a violation of Fourth Amendment protections 
against unreasonable searches and seizures. More specifically, one 
commenter stated the proposed rule was an attempt to provide authority 
to conduct warrantless searches by mandating registration, while other 
commenters believed the proposed rule would create a registry of 
personal property, which they stated would be unconstitutional as a 
random search or inspection without a warrant. Other commenters stated 
that the proposed rule would enable ATF to inspect or search private 
residences, check anyone's house or storage if they submitted the 
proposed notification, or go to their home and ask to see their 
gunpowder, violating the Fourth Amendment by conducting such searches. 
Multiple commenters stated it is not the government's business to know 
how much gunpowder or other materials individuals legally own or store 
on their private property. A commenter believed ATF was proposing the 
rule because the agency wants to go into homes to inspect ammunition 
and know where it is stored.
    Many commenters believed the proposed rule would violate the Fifth 
Amendment's right against self-incrimination. One commenter more 
specifically stated that the rule would violate the Fifth Amendment 
because it would require ``mandatory self-reporting for small amounts 
of privately owned black powder or smokeless powder and the ability to 
inspect at any time.''
ATF Response
    ATF disagrees with the commenters' First Amendment objections. This 
rule does not regulate speech. Moreover, storing explosive materials is 
not expressive conduct. Even if somehow considered expressive conduct, 
this rule does not target that expressive activity. The First Amendment 
is therefore not implicated. See Arcara v. Cloud Books, Inc., 478 U.S. 
697, 707 (1986) (First Amendment scrutiny ``has no relevance to a 
statute directed at . . . non-expressive activity.''); see also Wright 
v. City of St. Petersburg, 833 F.3d 1291, 1298 (11th Cir. 2016) 
(``First Amendment scrutiny `ha[d] no relevance to [a trespass 
ordinance] directed at imposing sanctions on nonexpressive activity.' 
''); cf. Talk of the Town v. Dep't of Fin. & Bus. Servs. ex rel. Las 
Vegas, 343 F.3d 1063, 1069 (9th Cir. 2003) (holding that a section of 
the Las Vegas Code barring consumption of alcohol in places that lack 
valid liquor licenses ``in no way can be said to regulate conduct 
containing an element of protected expression''). Conduct may be 
expressive where ``[a]n intent to convey a particularized message [is] 
present, and . . . the likelihood [is] great that the message would be 
understood by those who viewed it.'' Texas v. Johnson, 491 U.S. 397, 
404 (1989) (quoting Spence v. Washington, 418 U.S. 405, 410-11 (1974)). 
The rule would not regulate conduct that intends to convey any 
particularized message, and the commenters have not offered any valid 
reason to believe that storing explosives constitutes expressive 
conduct. As such, the First Amendment does not apply to the generally 
applicable regulatory requirement to annually submit a notice about 
stored explosives to the local fire safety authority.
    ATF also disagrees that the rule violates the Fourth Amendment or 
any constitutional right to privacy. ``The United States Constitution 
does not expressly guarantee a right to privacy, but the Supreme Court 
has held that a right to privacy does exist within the liberty 
component of the Fourteenth Amendment.'' See Padgett v. Donald, 401 
F.3d 1273, 1280 (11th Cir. 2005). Courts have recognized a privacy 
interest in avoiding disclosure of certain personal matters. See id. 
``[N]ot all disclosures of private information will trigger 
constitutional protection.'' Doe No. 1 v. Putnam County, 344 F. Supp. 
3d 518, 540 (S.D.N.Y. 2018) (finding courts have found a right to 
privacy in a ``limited set of factual circumstances'' involving one's 
personal financial or medical information, i.e., information of a 
``highly personal nature''). Information regarding stored explosives is 
of neither the medical nor financial variety, is not of a ``highly 
personal nature,'' and no court has found this information to be 
constitutionally protected.
    ATF further disagrees that the rule would result in a warrantless 
search or seizure in violation of the Fourth Amendment. The rule 
narrowly applies to storing explosive materials covered by ATF 
regulations in 27 CFR part 555. Because explosive materials may legally 
be distributed only to federal explosives licensees/permittees, persons 
storing explosive materials regulated by ATF will generally hold a 
federal explosives license/permit. Explosives licensees/permittees are 
aware that ATF may enter places where explosive materials are stored to 
inspect or examine required records or documents, and facilities in 
which explosives are stored, under 18 U.S.C. 843(f) and 27 CFR 555.24. 
There is no reasonable expectation of privacy in the information 
contained in those records. 18 U.S.C. 842(j) makes it unlawful for any 
person to store explosive materials in a manner not in conformity with 
ATF regulations, and ATF regulations already require all persons who 
have regulated explosives to comply with the storage requirements in 
part 555, subpart K.
    For those persons storing explosive materials who do not hold a 
federal license/permit, the requirement is merely a requirement to 
report the

[[Page 60810]]

presence of explosives for local fire safety purposes and retain the 
records so the person can verify they have met the notice requirement 
if asked, in conformity with 18 U.S.C. 842(j). Warrantless searches of 
property protected by the Fourth Amendment are per se unreasonable 
subject only to a few specifically and well-delineated exceptions. See 
Kentucky v. King, 563 U.S. 452, 459 (2011); United States v. Reedy, 989 
F.3d 548 (7th Cir. 2021); United States v. Rollins, 190 Fed. Appx. 739 
(2006). In addition, the rule, like every other regulation in 27 CFR 
part 555, would not apply to small-arms ammunition or components, or to 
commercially manufactured black powder in quantities not exceeding 50 
pounds (as well as percussion caps, safety and pyrotechnic fuses, 
quills, quick and slow matches, and friction primers) intended to be 
used solely for sporting, recreational, or cultural purposes in antique 
firearms as defined in 18 U.S.C. 921(a)(16) or in antique devices 
exempted from the term ``destructive device'' in 18 U.S.C. 921(a)(4), 
as they are exempt from the provisions of 27 CFR part 555 pursuant to 
18 U.S.C. 845(a)(4) and (5) and 27 CFR 555.141(a)(4) and (b).
    ATF acknowledges that the language in the proposed rule, which 
states that the individual must make ``each written notification . . . 
available for examination or inspection by an ATF officer at all 
reasonable times'' may lead to the incorrect conclusion that ATF may 
enter the premises of individuals who do not hold a federal license/
permit without a warrant for inspection purposes. Out of an abundance 
of caution, ATF is therefore removing that language from the final rule 
text.
    ATF disagrees that the rule would violate the Fifth Amendment right 
against self-incrimination. The Fifth Amendment protects against 
disclosures that could be used against a person in a later criminal 
prosecution. However, the rule would require annual reports about 
stored explosives, which is a regulatory issue, not a criminal one. See 
United States v. Spiezio, 523 F. Supp. 264, 269 (E.D. Pa. 1981) 
(holding that 18 U.S.C. 842(f), which requires licensees to report 
information on persons to whom explosive materials are distributed, did 
not compel defendants to incriminate themselves in violation of their 
rights under U.S. Const. amend. V, cl. 3, in that the privilege under 
Const. amend. V, cl. 3 is not violated by reporting requirements of a 
regulatory nature that apply to lawful activities, and explosives are 
not inherently criminal, but are inherently dangerous so that Congress 
had a legitimate aim in controlling explosives); see also United States 
v. Bouknight, 493 U.S. 549, 556 (1990) (``The Court has on several 
occasions recognized that the Fifth Amendment privilege may not be 
invoked to resist compliance with a regulatory regime constructed to 
effect the State's public purposes unrelated to the enforcement of its 
criminal laws.''); United States v. Wilson, 98 F.4th 1204, 1225 (10th 
Cir. 2024) (holding where a statutory or regulatory scheme requiring 
records to be kept is not aimed primarily at criminal activities, or at 
groups inherently suspect of criminal activities, and is ``constructed 
to effect the State's public purposes unrelated to the enforcement of 
its criminal laws,'' no Fifth Amendment protection applies).
    The rule is aimed at annual reporting on stored explosive materials 
to appropriate officials for fire officials' safety. The rule is not 
intended to target or investigate criminal activity, nor is it directed 
at any person suspected of criminal activity. Because the rule is 
regulatory in nature, the Fifth Amendment is not implicated, and 
therefore does not apply.
c. Violates the Ninth, Tenth, and Fourteenth Amendments
Comments Received
    One commenter also stated the rule would violate the Ninth 
Amendment but did not add an explanation.
    A small number of commenters expressed concerns that the proposed 
rule violated the Tenth Amendment. One commenter advised that, per the 
Tenth Amendment, any rights not given to the federal government are 
given to the states, which they said means that any regulation of 
explosive materials storage should be handled at the local, not the 
federal, level. Another commenter made the same statement about 
regulating personal gunpowder storage.
    Several commenters stated that the proposed rule would violate the 
Fourteenth Amendment. One commenter stated that implementing the 
proposed rule would violate the Fourteenth Amendment by targeting and 
criminalizing those who reload ammunition and store materials to do so, 
if they fail to report their stores. Another commenter stated that, if 
any exemptions for police or other organizations are added to the rule, 
it would violate the equal application of law clause of the Fourteenth 
Amendment. One commenter stated that the proposed rule would deprive 
them of rights under the color of law. Two commenters expressed concern 
that the proposed rule would violate their right to privacy.
ATF Response
    One commenter stated the proposed rule would violate the Ninth 
Amendment, which states, ``[t]he enumeration in the Constitution, of 
certain rights, shall not be construed to deny or disparage others 
retained by the people.'' U.S. Const. amend. IX. This commenter did not 
explain how they thought the proposed rule violated this constitutional 
provision.
    ATF disagrees that the rule violates the Ninth Amendment. Rather 
than enunciating a particular affirmative right, the Ninth Amendment 
serves to protect other fundamental rights that are not set forth in 
the Constitution. Charles v. Brown, 495 F. Supp. 862, 863 (N.D. Ala. 
1980). Some unenumerated rights may be of constitutional magnitude, but 
only by virtue of other amendments, such as the Fifth or Fourteenth 
Amendment. Id. at 864. A person cannot claim a right that exists solely 
under the Ninth Amendment. Id. at 864. Cf. Dobbs v. Jackson Women's 
Health Org., 597 U.S. 215, 231 (2022) (holding the Due Process Clause 
of both the Fifth and Fourteenth Amendments only protect rights that 
are ``deeply rooted in this Nation's history and tradition'' and 
``implicit in the concept of ordered liberty.'').
    ATF does not believe that an annual reporting requirement, designed 
to ensure the safety of emergency response personnel, denies any 
unenumerated right that is ``deeply rooted in this Nation's history and 
tradition'' or ``implicit in the concept of ordered liberty'' protected 
under the Ninth Amendment or under any other constitutional amendment. 
Dobbs, 597 U.S. at 231; see also United States v. Kuehnoel,187 F.3d 649 
(9th Cir. 1999) (the defendant was convicted of possessing a pipe bomb 
and argued the conviction was in violation of his Ninth Amendment 
rights; the Court disagreed, ``[w]e have observed that the Ninth 
Amendment `has not been interpreted as independently securing any 
constitutional rights.' ''); accord United States v. Broussard, 80 F.3d 
1025, 1041 (5th Cir.), cert. denied, 519 U.S. 906 (1996). No 
fundamental right would be infringed upon or denied as a result of the 
rule; therefore, the Ninth Amendment is inapplicable.
    ATF disagrees that the rule violates the Tenth Amendment. 
Commenters correctly stated that the Tenth Amendment reserves to the 
states rights not given to the federal government. However, they were 
incorrect in their conclusion that therefore, regulating

[[Page 60811]]

explosive materials should be reserved for the states. The Commerce 
Clause of the Constitution, art. 1, Sec.  8, cl. 3, states that 
``Congress shall have the Power . . . to regulate Commerce . . . among 
the several States . . . .'' Therefore, when Congress acts within its 
power under the Commerce Clause, ``the Tenth Amendment expressly 
disclaims any reservation of that power to the States.'' See New York 
v. United States, 505 U.S. 144, 156 (1992).
    Simply put, a valid exercise of Congress' power as delegated to it 
by the commerce clause is not a violation of the Tenth Amendment. 
Multiple courts have repeatedly and consistently upheld the federal 
explosives laws as a valid exercise of Congress' power to regulate 
commerce. See, e.g., United States v. Joos, 638 F.3d 581, 586 (8th Cir. 
2011) (holding that 18 U.S.C. 842(i), which prohibits a felon from 
possessing any explosive, fell within Congress's power under the 
Commerce Clause); United States v. Folen, 84 F.3d 1103, 1104 (8th Cir. 
1996) (holding that making possession of explosives unlawful based on 
connection to commerce is within Congress' power under the Commerce 
Clause); see also United States v. Disney, 62 M.J. 46, 49 (C.A.A.F. 
2005) (holding that storing stolen explosives had a direct substantial 
impact on commerce); United States v. Dawson, 467 F.2d 668, 673 (8th 
Cir. 1972) (holding that receiving, transporting, selling, or storing 
explosives is an activity that affects commerce); see also United 
States v. Grimes, 142 F.3d 1342 (11th Cir.1998) (holding argument that 
18 U.S.C. 844(i) is facially unconstitutional is without merit).
    ATF also disagrees with the commenter who stated the proposed rule 
would violate the Fourteenth Amendment by targeting and criminalizing 
those who reload ammunition and store materials. As previously 
discussed, the rule would not apply to small-arms ammunition and 
components thereof, or to commercially manufactured black powder in 
quantities not exceeding 50 pounds (as well as percussion caps, safety 
and pyrotechnic fuses, quills, quick and slow matches, and friction 
primers) intended to be used solely for sporting, recreational, or 
cultural purposes in antique firearms as defined in 18 U.S.C. 
921(a)(16) or in antique devices exempted from the term ``destructive 
device'' in 18 U.S.C. 921(a)(4). See 18 U.S.C. 845(a)(4) and (a)(5). 
Ammunition reloaders fall into this exception and thus would not be 
impacted by the rule. But in addition, the Fourteenth Amendment's Due 
Process Clause does not apply to federal action and is therefore not 
applicable to this rule, as explained more below.
    ATF disagrees that the rule would violate the Fourteenth Amendment 
because it would deprive individuals of their rights under the color of 
law. The Fourteenth Amendment provides that ``No State shall make or 
enforce any law which shall abridge the privileges or immunities of 
citizens of the United States.'' U.S. Const. amend. XIV. The rule does 
not operate under the color of state law; it is based on federal 
explosives law under 18 U.S.C. chapter 40, and therefore the Fourteenth 
Amendment is simply not applicable.
    ATF disagrees that any exemption added to this rule to exempt 
police or other organizations would violate the ``equal application of 
the law'' clause of the Fourteenth Amendment. ATF is unable to address 
the commenter who mentioned a hypothetical exemption for police or 
other organizations in the proposed rule and alleged that it violates 
the Fourteenth Amendment. Although 18 U.S.C. 845 enumerates specific 
provisions and exceptions to certain federal explosives laws, it is not 
clear what exception the commenter references or what type of 
hypothetical exception the commenter envisions that would violate the 
Fourteenth Amendment. However, the commenter's argument that this rule 
violates the Equal Protection Clause of the Fourteenth Amendment is 
meritless. The Equal Protection Clause forbids only intentional 
discrimination. McCleskey v. Kemp, 481 U.S. 279, 292 (1987); Horner v. 
Ky. High Sch. Athletic Ass'n, 43 F.3d 265, 276 (6th Cir. 1994). Even if 
``a neutral law has a disproportionately adverse effect . . . it is 
unconstitutional under the Equal Protection Clause only if that impact 
can be traced to a discriminatory purpose.'' Personnel Administrator of 
Mass. v. Feeney, 442 U.S. 256, 272 (1979); see also Soto v. Flores, 103 
F.3d 1056, 1067 (1st Cir. 1997) (``It is a truism that under Equal 
Protection Clause jurisprudence, a showing of disproportionate impact 
alone is not enough to establish a constitutional violation.''). 
``Discriminatory intent'' requires that the ``decisionmaker selected or 
reaffirmed a particular course of action at least in part `because of,' 
not merely `in spite of' the law's differential treatment of a 
particular class of persons.'' SECSYS, LLC v. Vigil, 666 F.3d 678, 685 
(10th Cir. 2012) (Gorsuch, J.) (alteration and some quotation marks 
omitted) (citing Feeney, 442 U.S. at 279). Consequently, ``when the law 
under review is generally applicable to all persons, no presumption of 
intentional discrimination arises; proof is required. This is so 
because many laws, perhaps most and often unavoidably, affect some 
groups of persons differently than others even though they involve no 
intentional discrimination.'' Id. (emphasis in the original).
    This rule is generally applicable to all persons who store 
explosive materials as required by federal law. Nothing in this rule 
creates discrete, objectively identifiable classifications which treat 
similarly situated people differently based on a particular class of 
persons. See San Antonio Indep. Sch. Dist. v. Rodriguez, 411 U.S. 1, 60 
(1973) (Stewart, J., concurring); Tex. Entertainment Ass'n v. Hegar, 10 
F.4th 495, 513 (5th Cir. 2021); Corey Airport Servs., Inc. v. Clear 
Channel Outdoor, Inc., 682 F.3d 1293, 1296-97 (11th Cir. 2012). Because 
the commenter did not identify a specific exception, it is unclear that 
there is any disparate impact on a certain class of individuals; but 
even if that impact existed, it would not be based on a discriminatory 
purpose.
    ATF disagrees with the two commenters who expressed concern that 
the proposed rule would violate their right to privacy under the 
Fourteenth Amendment for the same reasons previously discussed under 
ATF's response to comments on the Fourth Amendment's right to privacy 
earlier in this section of the preamble.
4. Improper Registry and Other Use or Loss of Reported Information
Comments Received
    A significant number of commenters expressed general concerns that 
the proposed rule was an attempt to collect data and create an illegal, 
de facto, or back-door registry of lawful individuals storing reloading 
materials, ammunition, and firearms. For example, one commenter stated 
the proposed rule was a blatant attempt to create unofficial 
registration of firearms, and another added that Congress has 
explicitly barred ATF from creating a registry of firearm owners in the 
Firearm Owners Protection Act. Another commenter expressed concern that 
any executive administration, standing army, or foreign power which 
sought to disarm and rule the American people, would need only obtain 
reports generated under this proposed rule to have the information they 
needed. One commenter stated the collected information could easily be 
added to ``ATF's firearm ownership database,'' while another added that 
mandatory gun registries have historically led to confiscation 
measures.

[[Page 60812]]

    Many commenters stated that, if the proposed rule was really based 
on safety concerns, local fire departments would be requesting this 
information themselves; therefore, they stated, the reason for the 
proposed rule was to create ``another unconstitutional registry'' that 
could be used against good citizens of this country. One commenter 
specified that they would support the rule for safety purposes if it 
was initiated by the local fire department rather than ATF and if they 
knew the information would not be transferred to ATF.
    Some commenters raised concerns specifically about the use of local 
reporting as a subterfuge to create an illegal federal registry. One 
such commenter stated that the proposed rule was a tactic to get around 
the federal prohibition against a national gun registry by allowing 
local agencies to maintain such a registry. This same commenter added 
that the federal government could demand copies of these local 
registries. Another commenter stated that this rule could use local 
firefighters to spy on what lawful citizens own in the name of safety. 
Other commenters added that history has shown that the government can 
use a registry to disarm citizens even if the citizens are only 
reporting to local fire departments or police departments.
    A significant number of commenters expressed concerns that the 
reporting requirement was particularly directed at gaining information 
to use to confiscate ammunition, gunpowder, and other explosive 
materials persons use to make ammunition. A number of commenters 
stated, for example, that the information collected under the proposed 
rule would be used not only for registration, but as a subterfuge for 
monitoring and confiscating gunpowder, ammunition, and firearms, and to 
incarcerate innocent people as a result. Another set of commenters 
similarly stated the proposed rule would create a registry of 
ammunition reloaders in order to track and find out where people keep 
gunpowder. A couple of commenters stated the proposed rule would 
provide ATF with a continuously updated registry of everyone that 
reloads their own ammunition or of reloading components in the guise of 
first responder safety, while another commenter described it as 
``fishing'' for data on individual reloaders, and others believed the 
ultimate goal of the reporting requirements was to suppress ordinary 
citizens from engaging in this activity, or to adversely impact them 
for engaging in activities protected under the Constitution. One 
commenter said the rule was designed to keep any form of explosives or 
propellants from law-abiding citizens. Another commenter warned the 
information could be used to arbitrarily set a limit on how much 
material used to make ammunition someone can store. One of these 
commenters also added that storing ammunition and gunpowder safely has 
never been a problem in this country, so the rule was clearly intended 
to target ammunition-making materials. Another commenter similarly 
stated that there are ``no significant issues related to powder 
storage,'' and that there are ``already tools in place, such as 
receiving a warrant, for problematic individuals.''
    Many commenters expressed concerns about how the reported 
information could subsequently be misused. For example, many considered 
the proposed rule to be a means of collecting information to create a 
paper trail on legally purchased items. Others expressed concerns that 
local authorities would share the reported information with law 
enforcement, insurance companies, etc., or that the purpose of the 
proposed rule was to leak individual names and addresses on the 
internet.
    On a related topic, commenters were concerned about how secure the 
information would be. For example, one commenter said gathering this 
kind of information would increase the chances of a data breach or data 
leak, and another commenter asked what would be done if these records 
were hacked. Another commenter asked how fire departments would be 
expected to track this information and keep it secure, while another 
commenter asked who would pay for data storage and security of the 
reports.
ATF Response
    The rule does not address, nor does it require, notification of 
firearms storage. The rule applies only to storing explosive materials 
that are already subject to ATF's explosives regulatory authority. It 
does not apply to explosive materials that are specifically exempt from 
ATF's regulations, which include small-arms ammunition and components 
thereof, and commercially manufactured black powder in quantities not 
exceeding 50 pounds (as well as percussion caps, safety and pyrotechnic 
fuses, quills, quick and slow matches, and friction primers) intended 
to be used solely for sporting, recreational, or cultural purposes in 
antique firearms as defined in 18 U.S.C. 921(a)(16) or in antique 
devices exempted from the term ``destructive device'' in 18 U.S.C. 
921(a)(4). See 18 U.S.C. 845.
    Additionally, the rule would not create a registry of explosives 
storage locations, or any other kind of registry for federal, state or 
local officials to access. The rule would require that all persons 
storing non-exempt explosives, who are already required to provide 
reports to local authorities when they begin storing non-exempt 
explosives, must also notify their local fire authority every 12 months 
thereafter if they continue to store explosive materials and when they 
cease storing the explosives, and must retain a copy of such written 
notification for five years as proof of compliance.
    Under the existing requirement to report the same information when 
beginning to store the covered explosives, local authorities have not 
shared this information with the ATF. To the best of ATF's knowledge, 
local authorities have also not shared this information with other 
persons or entities, like insurance companies. Local authorities are 
likely to share information on explosives with other officials to the 
extent necessary to address a fire-related situation, but there have 
been no issues with information being otherwise shared, and ATF has no 
reason to believe that would change with the additional notifications 
under this rule. Neither ATF nor local authorities have made a 
registry, particularly at a national level. There have also been no 
concerns raised by local authorities to ATF that their information 
would be hacked, or other similar scenarios raised in the public 
comments. As a result, ATF does not anticipate any of these concerns to 
be an issue arising from the additional annual reporting of the same 
information under the rule.
5. Lack of Clarity
Comments Received
    Numerous commenters opposed the proposed reporting requirement 
because they stated the rule was vague, unclear, or overbroad. A number 
of commenters stated generally that the proposed rule was written too 
broadly, which could lead to varied interpretation and abuse. One 
commenter said the proposed rule was intended to be broad so it could 
be used for surveillance purposes to erode the rights of law-abiding 
citizens. In a similar vein, a number of other commenters stated the 
proposed rule was too vague, and one added that the terms could 
potentially be redefined over time. One commenter said the rule was 
extremely inconsistent, and another

[[Page 60813]]

commenter stated that the rule was not thought out.
    Some commenters provided more specific information on ways in which 
they felt the rule was too vague. For example, a few commenters 
expressed that this rule should not be considered because it does not 
define what is an explosive or explosive material. Another commenter 
stressed that the proposed rule was a solution in search of a problem 
and did not include details on how local fire departments would track 
this information in such a way as to not create a database of gun 
owners.
    In addition, a number of commenters considered the proposed rule 
too vague because it did not specify what kinds of explosive materials 
would have to be reported. Numerous commenters stated the proposed rule 
did not define the types of explosives, define or name specific 
explosive materials, or the quantity that would have to be reported. 
Another commenter added that the proposed rule did not define how much 
explosive material would qualify as a hazard. Other commenters stressed 
that the proposed rule as written could apply to anything from 
hairspray, gasoline, fertilizers, to ammunition storage. One commenter 
added that many other household items could be considered an explosive, 
and if these items are required to be reported, the reporting process 
would be complicated and could overwhelm the system. And one commenter 
noted that ``the broad term of explosive material would [a]ffect every 
household in the United States,'' subjecting them to ``extreme 
recordkeeping requirements.'' Another commenter asked whether the 
proposed rule would subject ``someone buying fireworks for the Fourth 
of July or New Years'' to the reporting requirements or ``someone who 
reloads or stocks ammunition'' in their home because they hunt or are 
involved in shooting sports.
    Some commenters stated that the proposed rule was too broad with 
respect to single-, double-, and triple-based gunpowder/propellants 
used by many Americans. A couple of commenters stressed that this rule 
could create massive issues for the public because no one would know 
the specific amount of powder that must be reported, thus causing 
people to inadvertently break the law.
    Some commenters considered the rule too vague because they said it 
did not identify the penalty for failing to report explosives storage. 
One commenter stated the rule was unclear about specifics on how to 
report and to whom they should submit the report. Some commenters 
considered the proposed rule to be too ambiguous about who would have 
to report explosives storage. Several commenters stated the Department 
needs to clarify whether the rule applies to permittees, licensees, or 
``any person'' because, they emphasized, there is a huge difference 
between these groups. One commenter added that if the number applies to 
``any person,'' the estimated affected population number of 9,674, 
mentioned in the economic analysis part of the rule, was underestimated 
and objectionable. This commenter also stated that the Department also 
did not clarify whether the reporting requirement would apply to 
businesses or large entities that would be able to handle this 
requirement.
ATF Response
    ATF disagrees that the rule is too vague. Although the specific 
paragraph that would be revised by the rule does not explain which 
explosive materials are covered by the rule, that is because those 
details are explained in other provisions in the same regulation. The 
paragraph proposed for revision is not meant to be read alone; it is 
part of a larger set of regulatory provisions. The regulations also 
explain that the reporting requirements are applicable only to 
explosive materials that are subject to ATF's explosives regulations in 
27 CFR part 555. Additionally, there is an annual Federal Register 
notice, which identifies the kinds of explosives covered by the 
regulations. ATF acknowledges that some people may not be familiar with 
the rest of the explosives regulations and is providing further detail 
in these comment responses and elsewhere in the preamble to address 
that concern. However, ATF does not think that the regulation paragraph 
proposed for revision needs to be further revised to cross-reference 
regulations in the same part 555.
    Regarding comments specifically about who would be required to 
report, the paragraph proposed for revision, Sec.  555.201(f), clearly 
states at the beginning that it applies to ``any person'' who stores 
explosive materials. As a result, ATF does not agree with commenters 
who expressed that it was unclear as to whom the reporting requirement 
applies. It applies to all persons who store explosive materials 
covered by ATF explosives regulations. Persons who would be subject to 
the rule's annual reporting requirement are already subject to the 
existing initial reporting requirement in the current regulatory 
provision and should already be aware that they must notify the local 
fire authority when they begin storing explosives, or begin storing 
them in a new magazine. The rule does not change who must report on 
explosives storage, only how often. With regard to comments about 
penalties for failing to report as required by this rule, 18 U.S.C. 
chapter 40 provides the penalties for noncompliance with the storage 
requirements prescribed by the Attorney General. 18 U.S.C. 842(j) 
states in relevant part that ``[i]t shall be unlawful for any person to 
store any explosive material in a manner not in conformity with 
regulations promulgated by the Attorney General.'' The rulemaking 
merely requires individuals to comply with notification requirements 
for storing explosives. Failure to comply with this provision is a 
violation of section 842(j). A person who violates section 842(j) is 
subject to a fine or imprisonment of not more than a year. 18 U.S.C. 
844(b).
    With regard to comments about the kinds of explosives the rule 
might include, several earlier ATF responses in section III.B of this 
preamble address this topic. However, to clarify in the context of 
these comments on vagueness, the annual notice requirement proposed in 
Sec.  555.201(f) applies only to explosive materials that are subject 
to ATF regulations. ATF also annually publishes in the Federal Register 
a list of explosive materials that are subject to ATF's explosives 
regulations.\9\ The rule would not expand the types or classes of 
explosive materials that are subject to ATF's explosives regulations. 
Explosive materials that are specifically exempt from ATF's explosives 
regulations, such as consumer fireworks, small-arms ammunition, 
components of small-arms ammunition (e.g., primers, propellants), and 
commercially manufactured black powder (in quantities not exceeding 50 
pounds and intended to be used solely for recreational, sporting, or 
cultural purposes in antique firearms), are not subject to the proposed 
notice requirements. See 18 U.S.C. 845 and the 2025 Annual List of 
Explosive Materials, 90 FR 25077 (June 13, 2025). See also discussion 
in the ATF response under sections III.B.1 and 7 of this preamble.
---------------------------------------------------------------------------

    \9\ See, e.g., 2025 Annual List of Explosive Materials, 90 FR 
25077 (Jun. 13, 2025); 2024 Annual List of Explosive Materials, 89 
FR 67672 (Aug. 21, 2024).
---------------------------------------------------------------------------

    The household items mentioned as examples in several of the 
comments would also not be subject to ATF regulations or the proposed 
annual notice requirement because they are not considered explosive 
materials under federal explosives laws. This

[[Page 60814]]

information is already contained elsewhere in ATF regulations in 27 CFR 
part 555 (as well as 18 U.S.C. chapter 40), and the list published in 
the Federal Register. Therefore, ATF does not think it is necessary to 
repeat that detail or include a cross-reference to the relevant 
sections of the same part, in the paragraph in which the proposed 
revision to the notice requirement would occur. Nonetheless, ATF has 
added a clarifying phrase to address the scope more directly in that 
paragraph. This final rule therefore adds the phrase ``covered by this 
part'' to the first sentence, so it will read, ``Any person who stores 
explosive materials covered by this part must notify . . . .''
6. Effect on Law-Abiding Citizens
Comments Received
    Numerous commenters believed that the only purpose for the proposed 
rule was to illegally or inappropriately pursue, track, or watch law-
abiding gun owners, people who store gunpowder, or people the 
government considers to be a threat or problem. A number of commenters 
asserted that the proposed notice requirement constitutes harassment of 
law-abiding citizens and gun owners or was purposely designed to hurt 
and harass them. One commenter said they respected the public safety 
point of the rule, but they also thought the rule was preposterous 
because it targeted law-abiding taxpayers who own firearms. A number of 
commenters stated that the proposed rule was nothing but a way to 
control the livelihood of private citizens who have not broken any 
laws.
    Other commenters considered the rule to be an intrusion into the 
homes of private citizens without a warrant. Several recommended that 
ATF ``stay in their lane and stop intruding on law[-]abiding citizens, 
and stay out of their homes''; that people have the right to purchase 
and store explosives wherever they choose as long as it is done safely. 
A number of commenters more specifically stated that ATF does not need 
to know who has gunpowder, and the local fire department does not need 
to know unless there is a fire.
    Another commenter stated that the proposed rule was a way for the 
Department and ATF ``to keep their thumb on shooting sports 
enthusiasts.''
    In part because the proposed rule mentioned the OCCA, a number of 
commenters believed the proposed rule would cause law-abiding citizens 
who store gunpowder in their homes to be treated as, labeled, or made 
into criminals. Other commenters stated the proposed rule could 
potentially criminalize legal citizens who unknowingly have explosive 
materials in their homes and could potentially cause millions of 
Americans who would not even be aware that the proposed notice 
requirement occurred to be subject to criminal penalties. Some 
commenters stated that the proposed rule was aimed at targeting law-
abiding citizens even more than actual criminals or dangerous people of 
interest. And another commenter said the Department should stop 
pursuing law-abiding citizens who are defending themselves and focus on 
drug cartels and criminals with ``Glock switches.''
    Numerous commenters asserted that many commenters would not comply 
with this rule because it was inappropriately impacting law-abiding 
citizens. One commenter asked why gunpowder is just now being 
considered for safety purposes since it has been in existence for 
centuries.
ATF Response
    ATF disagrees that the rule will have an increased negative impact 
on law-abiding citizens. First, the rule does not impact firearms. It 
applies only to explosive materials covered by ATF regulations in part 
555, which does not include standard household items like those 
mentioned by commenters. More specifically, the rule would not apply to 
explosive materials that are expressly exempt from ATF's explosives 
regulations, such as consumer fireworks, small-arms ammunition, and 
components of small-arms ammunition (e.g., primers, propellant). In 
addition, the exempt explosive materials include commercially 
manufactured black powder in quantities not exceeding 50 pounds (as 
well as percussion caps, safety and pyrotechnic fuses, quills, quick 
and slow matches, and friction primers) intended to be used solely for 
sporting, recreational, or cultural purposes in antique firearms as 
defined in 18 U.S.C. 921(a)(16) or in antique devices exempted from the 
term ``destructive device'' in 18 U.S.C. 921(a)(4). See 18 U.S.C. 
845;2025 Annual List of Explosive Materials, 90 FR 25077 (June 13, 
2025); see also discussion in the ATF response under sections III.B.1 
and 7 of this preamble.
    Second, the rule would not affect persons who would not already be 
required to comply with ATF's explosives storage requirements at 27 CFR 
part 555, subpart K. Persons subject to the rule are already subject to 
the current notice requirement and should be aware that they must 
notify the local fire authority if they begin storing explosives or 
acquire a new magazine. If they have been complying with the existing 
requirement, they would be law-abiding citizens in this context. While 
they would be impacted by the proposed additional notice frequency, as 
described in response to comments under section III.B.1, ATF believes 
the impact would be minimal.
    However, citizens who should have notified local authorities of 
their explosives storage under the existing regulatory provision, but 
did not do so when they began storing their explosives, are already in 
violation of the existing notice requirement. The rule would increase 
how often a person must notify but would not change who must notify, 
the kinds of explosives that are covered, or what information must be 
reported. It also would not cause persons to be in violation of 
existing requirements. Persons who are violating the existing notice 
requirement but who comply with the proposed notice requirement would 
be impacted more by the rule than persons who are already complying 
with existing reporting requirements. This is because they would have 
to submit their first notice and determine who the local authorities 
are in response to the rule. But even so, the marginal impact of the 
proposed notice requirement would still be small; most of the impact 
would stem from complying with existing requirements in the first 
instance.
    ATF notes that the statute under 18 U.S.C. chapter 40 sets forth 
the penalty for failing to store explosives in compliance with the 
regulations as prescribed by the Attorney General. Persons who possess 
explosive materials that are already subject to ATF regulations are 
aware that they must comply with regulatory requirements, and that 
failure to comply with those regulatory requirements could result in a 
criminal penalty, particularly when storing explosives. 18 U.S.C. 
842(j) makes it ``unlawful for any person to store any explosive 
material in a manner not in conformity with regulations promulgated by 
the Attorney General.'' A violation of 18 U.S.C. 842(j) constitutes a 
misdemeanor offense under section 844(b) of the statute. These 
statutory penalties remain unchanged, and the proposed annual notice 
requirement would not create any new or additional criminal penalties. 
It affects a regulatory notice and would simply change the frequency of 
notices for those possessing explosive materials subject to ATF 
regulations.
    Sections of ATF regulations typically do not cite the statutory 
provision establishing the penalty. ATF generally does not include a 
statement in other sections of its regulations of the criminal penalty 
because the penalty is

[[Page 60815]]

statutorily established. Therefore, ATF does not feel it is necessary 
to add such a statement to the paragraph being proposed for revision 
because the criminal penalty is set forth in 18 U.S.C. chapter 40.
    ATF disagrees that this rule will punish law-abiding citizens 
storing gunpowder because the rule references the OCCA. The primary 
federal statute regulating explosives and arson is the OCCA, Title XI, 
as amended by the SEA, 18 U.S.C. chapter 40. One of the provisions of 
the SEA provides safeguards for storing, handling, packaging, and 
labeling explosives. As previously discussed, the rule does not apply 
to explosive materials that are specifically exempt from ATF's 
explosives regulations. See 18 U.S.C. 845 and the 2025 Annual List of 
Explosive Materials, 90 FR 25077 (June 13, 2025). See also discussion 
in the ATF response under sections III.B.1 and 7 of this preamble.
    ATF disagrees that the rule could potentially criminalize citizens 
who unknowingly have explosive materials in their home. 18 U.S.C. 
842(j) requires that all persons must store explosive materials in 
compliance with its requirements. The statute defines the term 
explosive materials and explosives, and it requires the Attorney 
General to report an annual list of explosives in the Federal Register. 
See 90 FR 25077 (June 13, 2025) for the current list. This provides 
law-abiding citizens with notice and knowledge of what explosives must 
be stored in compliance with 18 U.S.C. 842(j), and thus what explosives 
would be subject to the notification requirement in this rule.
    ATF disagrees that the rule targets law-abiding citizens more than 
criminals. As previously stated, all persons must store explosives in 
accordance with federal law and corresponding regulations. It is 
important that first responders are aware of explosives storage when 
responding to a fire site so they can be prepared when taking action 
that accounts for the explosives in an emergency response. This goal of 
the rule is to improve safety for emergency responders and the public.
    With regard to the commenters who stated that the proposed notice 
requirement was designed and intended to harm and harass people, ATF 
disagrees. The additional notice frequency would have minimal impact on 
those who are required to submit notices. As the rule would not expand 
who is covered or what types of explosive materials are covered, it is 
not harassing or harming people as these persons are already required 
to submit such a notice when they begin storing covered explosives. In 
addition, because there are exemptions for several kinds of explosives, 
including small-arms ammunition and commercially manufactured black 
powder not exceeding 50 pounds, used solely for sporting, recreational, 
or cultural purposes in antique firearms or devices, the rule would 
also not impact, harm, harass, or deny, persons who make their own 
ammunition for such purposes because, just as the current notice 
requirement does not apply to them, the rule would not apply to them.
    Rather, ATF proposed this notice requirement because it has an 
important impact on the safety of those who respond to fires, and 
people living or working near explosives storage sites. For more 
details on this safety basis, see section III.B.7 of this preamble.
    The proposed notice requirement also does not create an 
authorization for ATF to come into peoples' homes without a warrant, 
nor would it result in a warrantless search or seizure in violation of 
the Fourth Amendment. See discussion in section III.B.3.b of this 
preamble. The rule narrowly applies to storing explosive materials 
covered by ATF regulations in 27 CFR part 555. Because explosive 
materials may legally be distributed only to federal explosives 
licensees/permittees or exempt government agencies, persons storing 
explosive materials regulated by ATF will generally hold a federal 
explosives license/permit. Explosives licensees/permittees are aware 
that ATF may enter places where licensees/permittees store explosive 
materials to inspect or examine required records or documents, and the 
storage facilities, under Sec.  555.24. ATF may not enter locations 
merely to inspect explosives stored by persons who do not hold a 
federal license/permit. The rule does not change this. Therefore, for 
those persons who do not hold a federal license/permit, ATF would 
continue to have no right of warrantless entry to inspect explosive 
materials stored at that location.
    ATF acknowledges that the language in the proposed rule which 
states that the individual must make ``each written notification . . . 
available for examination or inspection by an ATF officer at all 
reasonable times'' may lead to the incorrect conclusion that ATF may 
enter the premises of individuals who do not hold a federal license/
permit without a warrant for inspection purposes. Out of an abundance 
of caution, ATF is therefore removing that language from the final rule 
text.
7. Does Not Enhance Public Safety
Comments Received
    Some commenters believed the proposed annual notice requirement 
would do nothing to stop gun violence and would not make communities 
safer. One commenter acknowledged the importance of public safety, but 
said the proposed rule failed to address the core issues surrounding 
gun violence and thus would not aid public safety. Other commenters 
stated that the rule showed insufficient evidence that the requested 
level of notices would be necessary or would significantly reduce crime 
and enhance public safety.
    Some commenters focused more specifically on the proposed notice 
requirement as a means of increasing safety and risk assessment 
planning for first responders. These comments were predicated on the 
idea that common hazardous materials are more dangerous than explosives 
or that explosions on residential properties are not an issue. For 
example, one commenter stated that according to their research, most 
emergency responders and the public are injured or killed by common 
hazardous materials, which would not be covered by the proposed notice 
requirement, and it would thus serve little purpose. This commenter 
added that chemicals such as propane, butane, chlorine, anhydrous 
ammonia, ammonium nitrate, ethanol, crude oil, hydrocarbon fuels, and 
liquefied petroleum gas are the major killers of emergency responders 
and in particular, firefighters. Other commenters indicated that the 
rule did not establish that smokeless or black powder is a serious risk 
to firefighters. One of these commenters stated that the rule did not 
include the actual number of serious injuries or persons killed from 
explosions at residential properties within the last ten years, and 
therefore the Department should not pursue the proposed regulation 
unless it can show data of numerous deaths from explosions on 
residential properties, and provide verifiable data that shows the 
risks that firefighters have experienced.
    A couple of other commenters considered notices on explosives 
storage to be pointless. One commenter specified that 911 operators 
already ask about hazardous materials at a location and they report 
that information to the fire department, so notifying fire authorities 
of such information would be redundant. This commenter added that 
during an emergency, the fire department is not going to stop and 
search files for notices. Another commenter stressed that ``anyone with

[[Page 60816]]

even the most basic of fire training understands that there are dangers 
hidden within homes, from O2 cylinders to propane bottles; we need to 
watch the fire's behavior and not the special note on a computer screen 
that is usually out of date and useless. The government has shown over 
and over that you are ineffective at even the most basic levels of 
security and safety.''
    A few commenters considered the notice requirement to be pointless 
because gunpowder does not give rise to crime. One commenter stated 
that the agency failed to show how this rule resolved a crime problem, 
and another stated that smokeless powder is rarely used in criminal 
acts. One commenter stated that according to their research, there is 
no evidence that criminals or violent organizations purchase and store 
large amounts of gunpowder to commit crimes.
    A number of commenters raised issues with treating gunpowder or 
smokeless gunpowder as an explosive and asserted that it is not a risk 
to public safety. Several commenters stated that, while modern 
smokeless gunpowder is flammable rather than an explosive, two stated 
that it is only an explosive when not stored in compliance with current 
regulations, and one added that it also is not a firearm. Another 
commenter who reiterated that smokeless gunpowder is not an explosive, 
also asked under what authority it was being reclassified as one. Other 
commenters added that smokeless gunpowder is not dangerous when stored 
properly in private homes, and a couple of commenters stressed that 
there is no justifiable data showing that people who store gunpowder in 
their homes pose a fire hazard or a significant threat. Another couple 
of commenters said they do not remember hearing about any explosions or 
increased fire damage caused by reloading powder storage.
    One commenter does not believe the rule will be effective because 
it does not provide guidance on safe storage practices.
    A few commenters said this rule would not only fail to provide any 
protection, it would also create a burden for the public as well as 
local firefighters. While one commenter felt it made sense to know if 
explosive materials are being stored, they stated there was no need to 
collect this information for small amounts of the average household 
items (e.g., yard fertilizer, black powder, paint thinners, small 
amounts of gunpowder for reloading, lighter fluid, propane tanks). The 
commenter stated that the notice requirement for household items would 
be an overwhelming and complicated process, and lives could be lost if 
fire departments have to check an extensive registry before fighting a 
house fire. Another commenter stated that they believed it was 
essential for the federal government to maintain public safety while 
maintaining the rights of Americans; however, the proposed rule could 
inadvertently discourage citizens from storing gunpowder responsibly 
which could potentially lead to unsafe practices. One commenter said 
the proposed rule would open a Pandora's box for the fireworks industry 
and other industries.
ATF Response
    ATF reiterates that the rule does not address firearms, firearms 
safety, or violence from firearms. The rule applies only to explosive 
materials that are subject to ATF's regulatory authority. The rule does 
not expand the type or class of explosive materials that are subject to 
ATF's explosives regulations or the existing notice requirement. The 
rule does not apply to explosive materials that are specifically exempt 
from ATF's explosives regulations, and covered explosive materials do 
not include the household items listed by commenters (e.g., yard 
fertilizer, black powder, paint thinners, small amounts of gunpowder 
for reloading, lighter fluid, propane tanks). See 18 U.S.C. 845 and the 
2025 Annual List of Explosive Materials, 90 FR 25077 (June 13, 2025). 
See also discussion in the ATF response under section III.B.1 of this 
preamble. The rule simply requires persons storing ATF-regulated 
explosive materials to notify the local fire authority every 12 months 
and when they cease storing explosives, in addition to the existing 
initial notice requirement, in order to increase first responder and 
public safety when fire or an explosion occurs at a location where 
explosives are being stored.\10\
---------------------------------------------------------------------------

    \10\ In 1998, ATF amended the regulations in 27 CFR part 55 (now 
part 555) to require that any person who begins storing explosive 
materials must notify the authority having jurisdiction for fire 
safety in the locality in which the explosive materials are being 
stored of the storage type, magazine capacity, and location of each 
site where such explosives are stored. The 1998 final rule was 
issued in response to numerous deaths and injuries sustained by 
emergency response personnel responding to fires and other 
emergencies at sites where explosives were stored without the 
knowledge of state and local officials. See RIN 1545-AU09, 61 FR 
53688 (Oct. 15, 1996).
---------------------------------------------------------------------------

    For example, as noted in section I of this preamble, firefighters 
and other fire safety officials generally do not attempt to fight a 
fire that involves explosive materials because of the potential for an 
explosion that could harm the responders. If officials know of the 
existence of explosives in such close proximity to a fire, they also 
typically evacuate the facility and the surrounding area to ensure the 
safety of the first responders and the public.
    Explosives industry members, association representatives, and 
firefighting organizations specifically identified the increased 
frequency in notifications to local authorities as one way to improve 
safety in discussions as part of the 2013 working group established by 
Executive Order 13650.\11\ They noted that local emergency response 
organizations may sometimes have high personnel turnover, which can 
cause the original report to be of less value as it might not come to 
the awareness of incoming personnel. Id. This may be more the case in 
locations that rely on volunteer or part-time personnel. They stated 
that the safety and security of explosives facilities, responders, and 
the surrounding communities would benefit from more frequent 
communications between persons who store explosives and local fire 
authorities. They also stated that more frequent communications would 
promote explosives site visits and training opportunities for fire 
responders. Id.

C. Comments Suggesting Changes

Comments Received
    Several commenters provided suggestions or recommendations to 
improve the rule. Most of these comments made suggestions about the 
types and amounts of explosives that should be included under the 
proposed rule's notice requirements. For example, some commenters 
stated that there needs to be a distinction between notifying about 
small and large amounts of storage, or the rule should require notices 
only for very large amounts of explosives. Another commenter suggested 
that the rule would serve the public better if it were extended to 
black powder, dynamite, nitroglycerin, semtex, and other high 
explosives used for lawful purposes.
    Other commenters suggested items that should be exempt from the 
annual notice requirement. Some commenters suggested that home 
reloading and muzzle-loading use should be exempt from notice 
requirements. Another commenter suggested that propellants manufactured 
strictly for the purpose of reloading sporting ammunition should

[[Page 60817]]

be exempt from this rule as that would minimize ATF's enforcement 
burden, minimize local fire department record-keeping burdens, and 
minimize the need for additional personnel to implement and enforce the 
proposed rule. One commenter suggested that powder and/or munitions 
should not be required for notices because there are so many other 
chemicals, aerosol, pesticides, thinners, cleaners, oil, and other 
combustibles in the average home and/or garage that are not reported 
annually.
    Other comments made suggestions as to how ATF could better approach 
the subject or expend its resources more usefully. One commenter 
suggested that it would be more beneficial if ATF focused on publishing 
a tutorial on how to safely store small quantities of explosives 
instead of mandating annual notice requirements. Another commenter 
recommended that the notice requirement be replaced with training 
guidelines for first responders to ask when they are initially 
contacted about a fire or upon their arrival at the scene of a fire. In 
reference to ensuring public safety, one commenter believed ATF should 
focus on comprehensive background checks, mental health initiatives, 
and educational programs instead of finalizing the rule. Three other 
commenters stated that the Department should work with people to ensure 
the safety of our communities without infringing on peoples' rights and 
imposing burdensome notice requirements on law-abiding citizens, and 
that it is crucial to strike a balance between personal liberties and 
public safety.
    One commenter suggested that the National Fire Prevention 
Association should be listed instead of ATF as a more appropriate 
agency to handle storage and notice requirements for hazardous 
materials.
ATF Response
    In response to the comments suggesting that distinctions should be 
made between which types of explosives are covered by the notice 
requirement, or recommending a variety of exceptions to the kinds of 
explosives covered, ATF believes the rule is clear that it is 
applicable only to explosive materials currently subject to ATF's 
explosives regulations in 27 CFR part 555. The rule does not expand the 
type or class of explosive materials that are currently subject to 
ATF's regulatory authority. Further, it does not require notification 
for explosive materials specifically exempt from ATF's explosives 
regulations. See 18 U.S.C. 845 and the 2025 Annual List of Explosive 
Materials, 90 FR 25077 (June 13, 2025). See also discussion in the ATF 
response under sections III.B.1 and 7 of this preamble. Persons subject 
to the rule are already subject to the existing notice requirement 
being proposed for revision, and should be aware of the current 
requirement to notify the local fire authority when they begin storing 
explosive materials subject to ATF regulations or they acquire a new 
magazine. The rule simply requires them to make notifications every 12 
months and when they cease storing explosives, in addition to the 
current requirement of notification when storage begins.
    With regard to comments suggesting that the paragraph proposed for 
revision, 27 CFR 555.201(f), include the types and amounts of explosive 
material that must be reported, and items that would be exempt from the 
notice requirements, ATF does not accept these suggestions. The 
paragraph proposed for revision is one paragraph in a full set of 
regulations on explosives. It is not intended to be read by itself, and 
other sections of the explosives regulations already contain the 
suggested information. In addition, ATF already publishes an annual 
list of explosive materials subject to ATF regulations in the Federal 
Register that updates the list with new developments in the explosives 
industry.
    ATF does not believe that developing training material on how to 
safely store small amounts of explosive material is a sufficient 
substitute for the rule. The regulations at 27 CFR part 555 already 
provide explosives licensees/permittees, and persons without an 
explosives license/permit, with the necessary requirements to safely 
and securely store explosive materials that are subject to ATF's 
explosives regulations. The rule will allow local fire authorities to 
develop their own response plans based on the information received from 
the annual notification. Training material cannot replace the 
information about the actual presence of explosives that local fire 
authorities would receive through the annual notification.
    ATF also disagrees that the National Fire Protection Association 
should be responsible for notifying local fire authorities of stored 
explosive materials. ATF, through the federal explosives laws, has been 
delegated the authority by Congress and the Attorney General to reduce 
the hazard to persons and property arising from misuse and unsafe or 
insecure storage of explosive materials. Additionally, ATF already 
requires that all persons storing explosive materials that are subject 
to 27 CFR part 555 must provide notice of those materials to local fire 
authorities; the rule just increases the frequency of those notices.

D. Comments on Economic Analysis

1. Need for Regulation
Comments Received
    Multiple concerns and questions were posed by commenters asking 
about the need to report on any combustible or explosive material that 
is normally stored in limited quantities at businesses or in homes 
(e.g., gasoline, fertilizer, swimming pool chemicals, propane, lithium 
batteries), with an overriding concern that the proposed rule would 
overwhelm citizens and businesses with burdensome notice requirements.
ATF Response
    ATF disagrees that the rule would apply to combustible materials 
such as gasoline, fertilizer, or swimming pool chemicals, which are not 
regulated explosive materials. The need for the rule was to ensure that 
first responders are aware of the location of magazines containing 
explosives stored by anyone storing regulated explosives. This would 
ensure that if a first responder were to respond to fires or explosions 
in the building or nearby, they would be aware of the hazardous 
conditions. Being aware of hazardous conditions in addition to the 
existence of a fire enables first responders to anticipate the 
potential need for specialized protective gear, determine alternate 
approaches or methods, account for ways in which different explosive 
materials might react to heat, and take other steps that might save 
lives and minimize damage to property.
2. Burden on the Public
Comments Received
    Many commenters stated the proposed rule was a waste of taxpayer 
money, time, and resources. Many commenters expressed concern regarding 
the burden the rule would place on the average citizen, businesses, and 
manufacturers due to all the additional notices and record-keeping that 
would result. One commenter expressed that the rule would cause 
extremely burdensome paperwork and record-keeping for the average 
citizen. The commenter also stated that the rule should not be allowed 
as it would ``create an additional burden on citizens just on the 
grounds of the Paperwork Reduction Act of 1995.''
ATF Response
    This rule applies only to persons who store explosive materials 
covered by

[[Page 60818]]

ATF explosives regulations in 27 CFR part 555. The rule would not 
expand or change who would be required to submit notices from those who 
are already required to report this information; it just increases the 
frequency. The vast majority of persons who would be impacted by the 
rule are already federal explosives licensees/permittees subject to 
other record-keeping requirements. Although the rule would also impact 
a small number of other persons who store explosive materials covered 
by ATF regulations but who do not have a license/permit, this is 
necessary to increase safety, as described in multiple portions of 
section III.B of this preamble. The proposed change to the storage 
notice requirement adds only minimal time or work. Persons subject to 
the proposed annual notice frequency are already required to report the 
same information to the same authorities when they begin storing 
explosive materials at a given site or in a new one. So, if there are 
no other changes from the prior notice, they would merely need to send 
the same letter with a new date and signature each year. If there is a 
change, updating the letter to reflect that change would require only 
minimal time. ATF estimates that this annual notice requirement would 
have an annual opportunity cost to licensees/permittees of five 
minutes.
3. Impact on Small Businesses
Comments Received
    One commenter emphasized that the rule would ``disproportionately 
impact small businesses and individuals, further exacerbating the 
regulatory burden they already face.'' One commenter posed several 
questions regarding who would pay for all the additional resources 
required to comply with the rule and stated that the economic impact 
numbers provided are incorrect. Another commenter indicated that if 
citizens are required to submit notices it will drive up the costs 
associated with homeowners' insurance.
ATF Response
    ATF disagrees that the rule would disproportionately impact small 
businesses and individuals. As discussed in several parts of section 
III.B of this preamble, the rule would not affect individuals storing 
commercially available combustible materials such as those typically 
found in residential households. It would apply only to persons who 
store explosive materials covered by ATF explosives regulations in 27 
CFR part 555. If a person is storing regulated explosive materials at 
their home, they should already be complying with ATF regulations for 
safely storing explosives in a magazine and accounting for the 
increased risk to their home of these materials through their 
homeowners' insurance. Merely notifying the local fire authority would 
not affect those requirements or costs. For all businesses and other 
persons covered by the rule, including small businesses, this rule will 
impose only a five-minute burden in any given year, which is a de 
minimis time burden and thus would not have a significant or 
disproportionate impact on small businesses.
4. Government Costs
Comments Received
    One of those commenters mentioned that the proposed annual notice 
requirement would be a ``logistical nightmare,'' while many others 
opined the rule would overwhelm and overburden already understaffed 
fire departments, especially those with more limited budgets (such as 
volunteer fire departments, small municipal departments, and those 
located in rural areas). One commenter added that the notice 
requirement would create a fiscal burden on local agencies and smaller 
fire departments. Another commenter stated that the proposed rule would 
put an undue burden on an already overworked agency (ATF). Another 
commenter stressed that the notice requirement would result in excess 
paperwork for firefighters. Another commenter opined that ``this 
proposal will create unnecessary paperwork for the local fire 
authority.'' The commenter also suggested that the proposed rule's 
annual cost should include the cost to local communities for the time 
and expense incurred by the local fire officials.
ATF Response
    ATF disagrees. ATF acknowledges that local fire departments or 
local municipalities will receive additional notices, which will 
involve receiving, routing, and organizing this information. However, 
ATF does not believe this is a significant paperwork burden on local 
fire departments or local municipalities. Additionally, the regulation 
does not require local jurisdictional authorities to do anything 
specific with these notices. Therefore, ATF cannot speculate as to how 
local jurisdictions will route or organize the notices. Furthermore, 
the paperwork burden for persons who would have to report on their 
regulated explosives storage once each year would be spread out among 
approximately 9,100 individuals and entities throughout the entire 
United States. Based on ATF's Federal Explosives Licensing Center 
(``FELC''), the number of individuals or entities currently notifying 
local authorities is approximately 600 or fewer persons per state, 
depending on the location of licensed/permitted explosives entities. At 
the local level, the number would be significantly smaller. The rule 
would not affect all individuals or all businesses that might carry 
small amounts of combustible materials.
5. Benefits
Comments Received
    One commenter suggested issues they felt needed clarification in 
the proposed rule's economic analysis section, such as providing better 
details on potential threats to first responders, costs associated with 
inspections, and potential alternatives. This commenter said the 
proposed rule needed to explain the connection between the list of 
explosives and actual fatalities or injuries to first responders.
ATF Response
    ATF disagrees that the rule should account for costs associated 
with inspections because the rule did not include a requirement for 
inspections, and they are not triggered by the notice requirement. ATF 
also disagrees that further explanation of the benefits of the rule's 
notice requirement is necessary for a rule that imposes a five-minute 
burden in a given year. Informing local fire authorities of explosives 
storage is already a requirement for all persons when they begin 
storing covered explosives and provides a benefit to fire authorities 
in managing, assessing, and responding to fires and other issues in 
their jurisdiction that might impact the stability of the explosives or 
endanger first responders and others. It also aids them in being better 
equipped and prepared for additional hazards if a fire occurs at the 
magazine. This rule simply adds to the frequency with which they must 
report the required information--from once when they begin to store the 
covered explosives to once when they begin, every 12 months thereafter, 
and when they cease storing the explosive materials, so that the local 
authority has up-to-date information--at minimal cost to copy, paste, 
and email. ATF responds to the comment about alternatives in the next 
section.
6. Alternatives
Comments Received
    Another commenter suggested that ATF consider alternative 
approaches

[[Page 60819]]

that prioritize education, responsible gun ownership, and collaboration 
with the firearms community.
ATF Response
    ATF disagrees with the proposed alternatives and with the previous 
commenter's assertion. This rule does not affect gun ownership; 
therefore, focusing on responsible gun ownership would not be 
applicable in this context. It also does not affect private citizens 
who are not storing explosive materials covered by ATF explosives 
regulations in 27 CFR part 555. In addition, private citizens who are 
storing covered explosives are already subject to the requirement to 
report this information; the rule only affects the notice frequency. 
All persons subject to the rule should already have completed at least 
one notice providing the required information to local authorities. 
They therefore should not need training or education on how to create 
or submit such a notice. First responders already know how to deal with 
the dangers of explosives for the area, and ATF regularly collaborates 
with firefighting and other first responder communities; the first 
responders just need to know where explosives are, the types of 
explosives, and the potential amount (as represented by the magazine's 
capacity) so they can be prepared to safely respond to a fire emergency 
involving a magazine. Federal explosives licensees/permittees, who 
constitute the vast majority of persons subject to the rule, are 
already required to be trained on safely storing explosive materials. 
Other persons who have questions on these subjects can review ATF's 
explosives website at <a href="http://www.atf.gov/explosives">www.atf.gov/explosives</a>.

IV. Final Rule

    The current regulation at 27 CFR 555.201(f) requires any person who 
stores explosive materials to provide to local fire safety officials an 
oral notification before the end of the day on which the person begins 
storing explosive materials subject to ATF's explosives regulations in 
27 CFR part 555 at that location, and in writing within 48 hours after 
they begin storing the explosives. Both forms of notification must 
include the storage type, magazine capacity, and location of each site 
where the person is storing such explosive materials.
    The proposed rule did not propose changes to the existing 
regulatory text but proposed adding to it. The proposed additions 
included a requirement for the person to submit written notice, 
covering the same information, once every 12 months following the 
initial notice until the person is no longer storing explosive 
materials at that site; a requirement that the person submit written 
notice within 48 hours after they cease storing explosives at that 
site; a requirement that the written notices must also include the 
notification date and the name, title, and agency of the authority 
official notified; and a requirement to retain the written notices for 
five years from the notice date, and make it available for examination 
or inspection by an ATF officer, as requested.
    This rulemaking finalizes the proposed rule by amending Sec.  
555.201(f) as proposed in the NPRM except the last clause relating to 
examination and inspection. Because public comments indicated that this 
language could lead to the incorrect conclusion that ATF may enter the 
premises of individuals who do not hold a federal license/permit, ATF 
is removing that language from the final rule. In addition, this rule 
adds the phrase ``covered by this part'' to the first sentence of the 
existing regulatory text, so it would read, ``Any person who stores 
explosive materials covered by this part must notify . . . .'' ATF is 
also making minor sentence structure edits to both the existing text 
and the proposed amendment text to conform with plain writing 
guidelines. Both the added phrase and these minor sentence structure 
edits are being made in response to public commenters who misunderstood 
that this notice requirement applies only to explosive materials 
covered by ATF explosives regulations.
    ATF is finalizing the proposed amendments because it believes 
notification every 12 months will increase public safety through 
increased communication between persons storing explosive materials and 
their local emergency responders; provide regularly updated storage 
information to local authorities; and allow for risk assessments and 
emergency response preparation prior to incidents, thus reducing 
potential safety and damage risk to first responders, emergency 
equipment, and other people around explosives storage sites.

V. Statutory and Executive Order Review

A. Executive Orders 12866 and 13563

    Executive Order 12866 (Regulatory Planning and Review) directs 
agencies to assess the costs and benefits of available regulatory 
alternatives and, if regulation is necessary, to select regulatory 
approaches that maximize net benefits.
    Executive Order 13563 (Improving Regulation and Regulatory Review) 
emphasizes the importance of agencies quantifying both costs and 
benefits, reducing costs, harmonizing rules, and promoting public 
flexibility.
    This rule amends 27 CFR 555.201(f) to require written annual 
notification to authorities having jurisdiction for fire safety of the 
existence of stored explosive materials. More specifically, Sec.  
555.201(f) already requires any person who stores explosive materials 
to notify authorities with jurisdiction for fire safety about the 
storage type, magazine capacity, and location of each site where such 
explosive materials are stored when the person begins storing the 
explosive materials. This rule adds a requirement for an updated report 
once every 12 months thereafter, and when the person discontinues 
storing the explosives. Annual notice to the local fire authority 
ensures they have current information on explosives storage in their 
area, which enables the fire authority to better plan for fires in such 
locations and take appropriate steps to account for explosives. This 
increases both the safety of first responders and of those in the areas 
around the magazine. The explosives industry and fire authorities 
support this reporting for these safety reasons. This requirement would 
take about five minutes to send an email every 12 months and thus 
involves de minimis cost to those submitting notices.
    The Office of Management and Budget (``OMB'') has determined that 
this rule is not a ``significant regulatory action'' under Executive 
Order 12866.

B. Executive Order 14192

    Executive Order 14192 (Unleashing Prosperity Through Deregulation) 
requires an agency, unless prohibited by law, to identify at least ten 
existing regulations to be repealed or revised when the agency publicly 
proposes for notice and comment or otherwise promulgates a new 
regulation that qualifies as an Executive Order 14192 regulatory action 
(defined in OMB Memorandum M-25-20 as a final significant regulatory 
action under section 3(f) of Executive Order 12866 that imposes total 
costs greater than zero). In furtherance of this requirement, section 
3(c) of Executive Order 14192 requires that any new incremental costs 
associated with such new regulations must, to the extent permitted by 
law, also be offset by eliminating existing costs associated with at 
least ten prior regulations. This rule, however, is not an Executive 
Order 14192 regulatory action because it is not a significant 
regulatory action as defined by Executive Order 12866 and it does not 
impose total costs greater than zero.

[[Page 60820]]

C. Executive Order 14294

    Executive Order 14294 (Fighting Overcriminalization in Federal 
Regulations) requires agencies promulgating regulations with criminal 
regulatory offenses potentially subject to criminal enforcement to 
explicitly describe the conduct subject to criminal enforcement, the 
authorizing statutes, and the mens rea standard applicable to each 
element of those offenses. This final rule does not create a criminal 
regulatory offense and is thus exempt from Executive Order 14924 
requirements.

D. Executive Order 13132

    This rule will not have substantial direct effects on the states, 
the relationship between the federal government and the states, or the 
distribution of power and responsibilities among the various levels of 
government. Therefore, in accordance with section 6 of Executive Order 
13132 (Federalism), the Acting Director has determined that this rule 
does not impose substantial direct compliance costs on state and local 
governments, preempt state law, or meaningfully implicate federalism. 
It thus does not warrant preparing a federalism summary impact 
statement.

E. Executive Order 12988

    This final rule meets the applicable standards set forth in 
sections 3(a) and 3(b)(2) of Executive Order 12988 (Civil Justice 
Reform).

F. Regulatory Flexibility Act

    Under the Regulatory Flexibility Act, 5 U.S.C. 601-612, agencies 
are required to conduct a regulatory flexibility analysis of any rule 
subject to notice-and- comment rulemaking requirements unless the 
agency head certifies, including a statement of the factual basis, that 
the rule will not have a significant economic impact on a substantial 
number of small entities. Small entities include certain small 
businesses, small not-for-profit organizations that are independently 
owned and operated and are not dominant in their fields, and 
governmental jurisdictions with populations of less than 50,000.
    The Acting Director certifies, after consideration, that this rule 
will not have a significant economic impact on a substantial number of 
small entities. ATF estimates that this rule will impact approximately 
9,100 persons, with 8,774 of those being licensees/permittees, and the 
majority of those being small businesses. However, ATF estimates that 
the additional notifications will take up to five minutes annually to 
provide written notification by email. It therefore does not impose a 
significant economic impact on small businesses or the industry as a 
whole.

G. Small Business Regulatory Enforcement Fairness Act of 1996

    This rule is not likely to have a significant economic impact on a 
substantial number of small entities under the Small Business 
Regulatory Enforcement Fairness Act of 1996, 15 U.S.C. 657 and 5 U.S.C 
601 note, as it imposes no additional costs.

H. Unfunded Mandates Reform Act of 1995

    This rule does not include a federal mandate that might result in 
the expenditure by state, local, and tribal governments, in the 
aggregate, or by the private sector, of $100 million or more in any one 
year, and it will not significantly or uniquely affect small 
governments. Therefore, ATF has determined that no actions are 
necessary under the provisions of the Unfunded Mandates Reform Act of 
1995.

I. Paperwork Reduction Act of 1995

    Under the Paperwork Reduction Act of 1995 (``PRA''), 44 U.S.C. 
3501-3521, agencies are required to submit to OMB, for review and 
approval, any information collection requirements a rule creates or any 
impacts it has on existing information collections. An information 
collection includes any reporting, record-keeping, monitoring, posting, 
labeling, or other similar actions an agency requires of the public. 
See 5 CFR 1320.3(c). This rule creates the need to revise an existing 
information collection under the PRA. The title and description of the 
information collection impacted by this rule, a description of those 
who provide the information, and an estimate of the total annual burden 
follow. The estimate covers the time for reviewing instructions, 
searching existing sources of data, gathering and maintaining the data 
needed, and completing and reviewing the collection.
    Title: Notifying Fire Safety Authority of Stored Explosive 
Materials.
    OMB control number: 1140-0071.
    Summary of the information collection: This regulation amends 27 
CFR 555.201(f) to require annual notice to authorities having 
jurisdiction for fire safety about explosive materials being stored in 
their jurisdiction. Currently, any person who stores explosive 
materials is required to notify authorities with jurisdiction for fire 
safety about the storage type, magazine capacity, and location of each 
site where such explosive materials are stored when the person begins 
storing the explosives at that location. This rule amends the 
regulation to require the person to also submit such notices annually 
thereafter, and when the person ceases to store explosives there. Any 
person storing explosive materials is also required to maintain a copy 
of the written notification for five years from the date of the notice.
    Need for information: It is important that first responders are 
aware of explosives storage when responding to a fire site. 
Firefighters and other fire safety officials generally do not attempt 
to fight a fire that has engaged a container of explosive materials 
because of the potential for an explosion that could harm the 
responders. Knowing that explosives are stored at the site, in close 
proximity to a fire, enables first responders to adjust their strategy 
for handling and responding to the fire in such cases to provide better 
public safety. The additional annual notice requirement provides local 
authorities with updated information from which to assess the potential 
danger from explosives at the site.
    Proposed use of information: To provide first responders advance, 
updated information about where explosives are stored, which enables 
them to better plan for and respond to fires in close proximity to such 
stored explosives, and increases public safety.
    Description of the respondents: Persons or entities who store 
regulated explosive materials.
    Number of respondents: 9,100.
    Frequency of response: once annually.
    Burden of response: 5 minutes.

J. Congressional Review Act

    Pursuant to the Congressional Review Act, 5 U.S.C. 801 et seq., 
OMB's Office of Information and Regulatory Affairs has determined that 
this rule does not meet the criteria in 5 U.S.C. 804(2) to constitute a 
major rule. This rule is not a major rule because it will not result in 
an annual effect on the economy of $100 million or more; a major 
increase in costs or prices; or significant adverse effects on 
competition, employment, investment, productivity, innovation, or on 
the ability of United States-based enterprises to compete with foreign-
based enterprises in domestic and export markets.

to it, and this final rule are available through the federal 
eRulemaking portal, at
