SUPPLEMENTARY INFORMATION: 

I. Background

    Title XI of the Organized Crime Control Act of 1970, Public Law 91-
452, added chapter 40 (``Importation, Manufacture, Distribution and 
Storage of Explosive Materials'') to title 18 of the United States Code 
(U.S.C.). One purpose of title XI is 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. 922, 952 
(1970).
    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 the ATF subject to the direction of the Attorney 
General and the Deputy Attorney General. See 28 CFR 0.130. Regulations 
in 27 CFR part 555 implement title XI.
    The regulations at 27 CFR 555.220 set forth a table of separation 
distances of ammonium nitrate and blasting agents from explosives or 
blasting agents (the Sec.  555.220 Table of Distances) followed by six 
explanatory notes. In this table, the term ``separation distance'' 
means the minimum distance that must be maintained between stores of 
certain materials, such as high explosives, and blasting agents. The 
third note states that the distances specified in the Sec.  555.220 
Table of Distances ``apply to ammonium nitrate that passes the

[[Page 30634]]

insensitivity test prescribed in the definition of ammonium nitrate 
fertilizer issued by the Fertilizer Institute'' in its ``Definition and 
Test Procedures for Ammonium Nitrate Fertilizer.''
    The Fertilizer Institute (TFI) is a voluntary, non-profit trade 
association that currently has more than 175 members. See Membership 
List, The Fertilizer Institute, http://www.tfi.org/about/membership-list (last visited August 19, 2014). Members include importers, 
wholesalers, retailers, and others involved in the fertilizer industry. 
Id. Many of TFI's members handle and store ammonium nitrate fertilizer 
and may be affected by the regulations at Sec.  555.220.
    The Agricultural Nitrogen Institute, a predecessor organization of 
TFI, first developed the ``Definition and Test Procedures for Ammonium 
Nitrate Fertilizer'' guidance document. See The Fertilizer Institute, 
Definition and Test Procedures for Ammonium Nitrate Fertilizer (Aug. 
1984), available at https://www.atf.gov/files/publications/download/hist/definition-and-test-procedures-for-ammonium-nitrate.pdf. In May 
1984, TFI assembled a task force of industry and government 
representatives who were ``experts on the physical and chemical 
characteristics of ammonium nitrate fertilizer'' to review and update 
the document. Id. ``Based on that review and the technical expertise 
and experience of the task force members, TFI published'' a revised 
guidance document in August 1984 (the August 1984 guidance). Id. The 
August 1984 guidance defines ammonium nitrate fertilizer as ``solid 
ammonium nitrate containing a minimum of 33.0% nitrogen, having a 
minimum pH of 4.0 in a 10% aqueous solution, 0.20% maximum carbon, 
0.010% maximum elemental sulfur, 0.150% maximum chloride as Cl, or 
particulated elemental metals sufficient to release 4.60 ml, maximum, 
of hydrogen from 50.0 gram sample and which will pass the detonation 
resistance test in Section 2.0 and the burning test in Section 4.0.'' 
Id. at 1.

A. The Fertilizer Institute Petition

    On March 19, 2002, TFI filed a petition with ATF requesting that 
ATF amend the explosives regulations at Sec.  555.220 to remove the 
reference to the August 1984 guidance. TFI explained that the document 
is outdated because TFI last published it in 1984, will not review or 
update it, and cannot ensure that its procedures are still valid. TFI 
recognized that ATF may require an alternate method of determining the 
insensitivity of ammonium nitrate fertilizer and suggested that ATF 
reference certain Department of Transportation (DOT) regulations.
    The DOT regulations include several definitions and two hazardous 
classifications (Class 5.1 and Class 9) for ammonium nitrate based 
fertilizers based on the amount of combustible material included in the 
fertilizer. See 49 CFR 172.101. Class 5.1 ammonium nitrate fertilizer 
is defined as a uniform mixture with ammonium nitrate as the main 
ingredient within the following composition limits: (1) Not less than 
90 percent ammonium nitrate with not more than 0.2 percent total 
combustible, organic material calculated as carbon, and with added 
matter, if any, that is inorganic and inert when in contact with 
ammonium nitrate; or (2) more than 70 percent but less than 90 percent 
ammonium nitrate with other inorganic materials, or more than 80 
percent but less than 90 percent ammonium nitrate mixed with calcium 
carbonate or dolomite or mineral calcium sulphate, and not more than 
0.4 percent total combustible, organic material calculated as carbon; 
or (3) ammonium nitrate-based fertilizers containing mixtures of 
ammonium nitrate and ammonium sulphate with more than 45 percent but 
less than 70 percent ammonium nitrate, and not more than 0.4 percent 
total combustible, organic material calculated as carbon such that the 
sum of the percentage of compositions of ammonium nitrate and ammonium 
sulphate exceeds 70 percent. See 49 CFR 172.101, 172.102(c)(1) code/
special provisions 52, 150. Class 9 ammonium nitrate fertilizer is 
defined as a uniform, ammonium nitrate-based fertilizer mixture 
containing nitrogen, phosphate, or potash with not more than 70 percent 
ammonium nitrate and not more than 0.4 percent total combustible, 
organic material calculated as carbon or with not more than 45 percent 
ammonium nitrate and unrestricted combustible material. See 49 CFR 
172.101, 172.102(c)(1) code/special provision 132. To determine whether 
a material falls within Class 5, Division 5.1, DOT requires regulated 
parties to conduct tests in accordance with international standards in 
the United Nations (UN) Manual of Tests and Criteria. See 49 CFR 
173.127(a).

B. Advance Notice of Proposed Rulemaking

    Based upon TFI's petition, ATF published in the Federal Register on 
September 16, 2010, an advance notice of proposed rulemaking (Notice 
No. ATF 26A, 75 FR 56489). ATF requested information from explosives 
industry members, trade associations, consumers, and all other 
interested parties to determine whether a replacement reference for the 
August 1984 guidance is necessary, and, if so, whether there are any 
alternate methods available to determine the insensitivity of ammonium 
nitrate fertilizer. ATF solicited comments on 10 specific questions as 
well as any relevant information on the subject. The comment period for 
Notice No. ATF 26A closed on December 15, 2010.

II. Analysis of Comments

A. Comments Received

    ATF received three comments in response to the advanced notice of 
proposed rulemaking. Two of the commenters are explosive and fertilizer 
trade associations, and one commenter is an associate member of an 
explosive and fertilizer trade association. All of the commenters 
support removing the reference to the August 1984 guidance and adopting 
DOT regulations for classifying ammonium nitrate fertilizer in 
accordance with the UN Manual of Tests and Criteria.
    The first commenter, the Institute of Makers of Explosives (IME), 
believes that ATF should amend note three following the Sec.  555.220 
Table of Distances to be consistent with the source document, Appendix 
A of IME Safety Library Publication 2,\1\ and Table 9.4.2.2(b) of the 
National Fire Protection Association's (NFPA) NFPA 495: Explosive 
Materials Code.\2\ IME noted that these two internationally recognized 
standards referenced the August 1984 guidance and replaced it with the 
following: ``The distances in the Table apply to ammonium nitrate and 
ammonium nitrate based materials that show a `negative' (-) result in 
the UN Test Series 2 Gap Test and show a `positive' (+) result in the 
UN Test Series 1 Gap Test. Ammonium nitrate and ammonium nitrate based 
materials that are DOT hazard Class 1 sensitive shall be stored at 
separation distances determined by the American Table of Distances.'' 
IME noted that DOT test procedures are ``suitable and internationally 
recognized at the United Nations'' and believes that ATF should 
harmonize its standards with those of DOT.
---------------------------------------------------------------------------

Materials Code 31 (2010), available at http://www.nfpa.org/codes-and-standards/document-information-pages?mode=code&code=495.

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

[[Page 30635]]

    The petitioner, TFI, submitted the second comment. Like IME, TFI 
noted that IME removed references to the August 1984 guidance from its 
Safety Library Publication 2, the American Table of Distances, and that 
the NFPA adopted the same test as IME in NFPA 495. TFI also commented 
that ATF references NFPA and IME in its Table of Distances. TFI, 
therefore, supports IME's position concerning the use of the UN Test 
Series 1 and 2 Gap Tests.
    The third commenter, an IME member company, fully supports IME's 
comments.

B. Department Response

    The Department does not agree that it should replace the current 
reference to the August 1984 guidance document with a reference to the 
UN Test Series 1 and 2 Gap Tests. The Department acknowledges that the 
United Nations has developed criteria, test methods, and procedures 
that are generally sufficient for competent authorities to use for the 
classification of dangerous goods during transport. See U. N. Econ. & 
Soc. Council, Recommendations on the Transport of Dangerous Goods: 
Manual of Tests and Criteria U.N. Doc. ST/SG/AC.10/11/Rev.5 (2009), 
available at http://www.unece.org/fileadmin/DAM/trans/danger/publi/manual/Rev5/English/ST-SG-AC10-11-Rev5-EN.pdf. However, these 
recommended test methods do not address all the hazards encountered 
during processes involving dangerous goods, such as storage. Existing 
literature indicates that fertilizer and technical grade ammonium 
nitrate prill can detonate under certain circumstances and that various 
factors--such as particle size, prill density, degree of confinement, 
temperature, and moisture content--can affect the detonability of 
ammonium nitrate prill.\3\ Those factors may develop during transport, 
handling, and storage, after the UN test criteria have been applied.

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

    In addition, ATF is unaware of any commercially-produced ammonium 
nitrate manufactured for use with, and stored in the proximity of, 
explosives that would not fall under the Sec.  555.220 Table of 
Distances, using the UN Test Series 1 and 2 Gap Tests under the 
commenters' proposed amendments. Because the UN tests would lead to all 
ammonium nitrate being subject to the Sec.  555.220 Table of Distances, 
the costs of imposing the extra step of those tests would outweigh any 
benefits.
    The Department thus proposes amending the third note following the 
Sec.  555.220 Table of Distances to delete the reference to the August 
1984 guidance and to state that all ammonium nitrate stored near high 
explosives and blasting agents is subject to the Sec.  555.220 Table of 
Distances. The Department believes this proposal will not negatively 
affect the explosives industry because most ammonium nitrate currently 
located near stores of high explosives and blasting agents are already 
subject to the Sec.  555.220 Table of Distances. Moreover, it is ATF's 
understanding that entities who store ammonium nitrate located near 
high explosives and blasting agents do not use the outdated August 1984 
guidance referenced in the existing regulations and instead comply with 
the Sec.  555.220 Table of Distances for all ammonium nitrate. This 
proposed removal of the reference to the outdated test does not address 
ammonium nitrate blends containing fuels. Generally, ammonium nitrate 
blends are subject to ATF's criteria for high explosives in Sec.  
555.202(a) or blasting agent in Sec.  555.11. Ammonium nitrate blends 
that meet the criteria are ammonium nitrate explosive mixtures and 
designated as such in ATF's List of Explosive Materials, which is 
published annually pursuant to 27 CFR 555.23.
    This proposed amendment will provide industry members with clear 
guidance on the application of these regulations governing the storage 
of explosive materials. Section 555.206(c)(2) states that all ammonium 
nitrate is subject to the separation distances requirements in Sec.  
555.220. The revision of the reference to the outdated August 1984 
guidance in note three following the Sec.  555.220 Table of Distances 
will make clear the application of the Table of Distances in 
relationship to all ammonium nitrate. All ammonium nitrate will be 
subject to the Sec.  555.220 Table of Distances when stored within the 
sympathetic detonation distances of high explosives and blasting 
agents. Ammonium nitrate explosive mixtures that are high explosives 
pursuant to Sec.  555.202(a) or are defined as a blasting agent 
pursuant to Sec.  555.11, will be subject both to the table of 
distances for storage of explosive materials in Sec.  555.218 and to 
the Sec.  555.220 Table of Distances. In this way, the proposed 
amendment will continue to protect public safety by ensuring that all 
stores of ammonium nitrate located within the sympathetic detonation 
distances to high explosives or blasting agents meet minimum distances 
to inhabited buildings, highways, and passenger railways.

III. Proposed Amendments to 27 CFR Part 555

    This proposed rule would amend the regulations of ATF governing the 
separation of distances of ammonium nitrate and blasting agents from 
explosives or blasting agents. The proposed rule would revise note 
three following the Table of Distances in 27 CFR 555.220 by removing 
the reference to the August 1984 guidance. The proposed rule would 
clarify that all ammonium nitrate is subject to 27 CFR 555.206(c)(2) 
and 555.220.

IV. Statutory and Executive Order Reviews

A. Executive Orders 12866 and 13563

    This proposed rule has been drafted and reviewed in accordance with 
Executive Order 12866, ``Regulatory Planning and Review,'' section 
1(b), The Principles of Regulation and in accordance with Executive 
Order 13563, ``Improving Regulation and Regulatory Review,'' section 1, 
General Principles of Regulation, and section 6, Retrospective Analyses 
of Existing Rules.
    Both Executive Orders 12866 and 13563 direct agencies to assess all 
costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select regulatory approaches that maximize 
net benefits (including potential economic, environmental, public 
health and safety effects, distributive impacts, and equity). Executive 
Order 13563 emphasizes the importance of quantifying both costs and 
benefits, of reducing costs, of harmonizing rules, and of promoting 
flexibility. The Department has assessed the costs and benefits of this 
regulation and believes that the regulatory approach selected maximizes 
net benefits.
    This proposed rule will not have an annual effect on the economy of 
$100 million or more, nor will it adversely affect in a material way 
the economy, a sector of the economy, productivity,

[[Page 30636]]

competition, jobs, the environment, public health or safety, or State, 
local, or tribal government or communities. Similarly, it does not 
create a serious inconsistency or otherwise interfere with an action 
taken or planned by another agency, materially alter the budgetary 
impact of entitlements, grants, user fees, or loan programs or the 
rights and obligations of recipients thereof, or raise novel legal or 
policy issues arising out of legal mandates, the President's 
priorities, or the principles set forth in Executive Order 12866. 
Accordingly, this proposed rule is not a ``significant regulatory 
action'' as defined in Executive Order 12866.
    Section 6 of Executive Order 13563, directs agencies to develop a 
plan to review existing significant rules that may be ``outmoded, 
ineffective, insufficient, or excessively burdensome,'' and to make 
appropriate changes where warranted. The Department selected and 
reviewed this rule under the criteria set forth in its Plan for 
Retrospective Analysis of Existing Rules, and determined that this 
proposed rule removes a reference to an outdated guidance document, 
clarifies the existing regulations, and continues to protect public 
safety. ATF welcomes public comment on its analysis of the proposed 
rule's likely effects.

B. Executive Order 13132

    This proposed rule will not have substantial direct effects on the 
States, on the relationship between the Federal Government and the 
States, or on the distribution of power and responsibilities among the 
various levels of government. Therefore, in accordance with section 6 
of Executive Order 13132, ``Federalism,'' the Attorney General has 
determined that this proposed rule will not have sufficient federalism 
implications to warrant the preparation of a federalism summary impact 
statement.

C. Executive Order 12988

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

D. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 605(b)) requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements unless the agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and small governmental 
jurisdictions. The Attorney General has reviewed this rule and, by 
approving it, certifies that this rule will not have a significant 
economic impact on a substantial number of small entities. This 
proposed rule updates the affected regulations by removing a reference 
to an outdated guidance document. The changes proposed in this rule are 
administrative and do not add any new requirements that would have any 
impact on the economy because: (1) The referenced test in explanatory 
note three was last published in 1984, is obsolete, and is not used by 
the explosives industry; and (2) the explosives industry already 
ensures their stores of ammonium nitrate are stored in accordance with 
the Sec.  555.220 Table of Distances.

 E. Small Business Regulatory Enforcement Fairness Act of 1996

    This proposed rule is not a major rule as defined by section 251 of 
the Small Business Regulatory Enforcement Fairness Act of 1996, 5 
U.S.C. 804. This proposed rule 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.

F. Unfunded Mandates Reform Act of 1995

    This proposed rule will not 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, no 
actions were deemed necessary under the provisions of the Unfunded 
Mandates Reform Act of 1995.

G. Paperwork Reduction Act

    This proposed rule does not impose any new reporting or 
recordkeeping requirements under the Paperwork Reduction Act.

V. Public Participation
