Notice of Availability of Redacted Ammonium Nitrate Security
Program Technical Assessments Report
AGENCY: Cybersecurity and Infrastructure Security Agency, DHS.
ACTION: Proposed rule; notice of availability of supplemental
information.
-----------------------------------------------------------------------
SUMMARY: The Department of Homeland Security is publishing this notice
of availability in connection with the proposed rule entitled
``Ammonium Nitrate Security Program'' that was published on August 3,
2011. Through this notice, DHS is making available a redacted version
of a final technical report developed by Sandia National Laboratories
titled ``Ammonium Nitrate Security Program Technical Assessments.'' The
report documents Sandia National Laboratories' technical research,
testing, and findings related to the feasibility of weaponizing
commercially available products containing ammonium nitrate. The
redacted report has been added to the docket for the proposed rule.
This notice solicits comments on the report and its application to the
proposed definition of ammonium nitrate included as part of the
Ammonium Nitrate Security Program rulemaking.
DATES: Comments are due by September 3, 2019.
ADDRESSES: You may send comments, identified by docket number and/or
RIN number, by any of the following methods:
Federal eRulemaking Portal: http://www.regulations.gov.
Follow the instructions for sending comments.
Mail: DHS/CISA/ISD/ISCD, ATTN: [DHS Docket No. DHS-2008-

receives a request to examine or copy this information, DHS will treat
it as any other request under the Freedom of Information Act (FOIA), 5
U.S.C. 552, and the Department's FOIA regulation found in part 5 of
Title 6 of the Code of Federal Regulations (CFR).

types of comments that would be most useful to DHS, see the ``Public
Participation'' heading of the SUPPLEMENTARY INFORMATION section of
this document.

SUPPLEMENTARY INFORMATION:
Background
Section 563 of the Fiscal Year 2008 Department of Homeland Security
Appropriations Act (Pub. L. 110-161, Division E (2007)), amended the
Homeland Security Act of 2002, and directs DHS to ``regulate the sale
and transfer of ammonium nitrate by an ammonium nitrate facility to
prevent the misappropriation or use of ammonium nitrate in any act of
terrorism.'' See 6 U.S.C. 488a(a). As part of this responsibility, DHS
must consult with the heads of appropriate Federal departments and
agencies and seek public comment in developing and implementing
ammonium nitrate regulations, including establishing a threshold
percentage for ammonium nitrate in a substance that will be subject to
regulation. 6 U.S.C. 488a(b). The Department published an Advance
Notice of Proposed Rulemaking (ANPRM) on October 29, 2008, seeking
public comment on a Secure Handling of Ammonium Nitrate Program, which
was followed by a Notice of Proposed Rulemaking (NPRM) for the Ammonium
Nitrate Security Program for public comment on August 3, 2011. 73 FR
64280 (October 29, 2008); 76 FR 46908 (August 3, 2011). Additionally,
DHS held public meetings to seek public input on the proposed rule and
questions raised in the NPRM. See 76 FR 62311 (October 7, 2011); 76 FR
70366 (November 14, 2011).
In the NPRM, 76 FR 46908 (August 3, 2011), the Department proposed
a definition of ammonium nitrate that included a minimum weight of 25
pounds, a minimum threshold of 30 percent ammonium nitrate by weight
for mixtures, and an exemption for cold packs. The Department developed
the proposed ammonium nitrate definition by considering the security
benefits gained from regulating a particular transaction and the
economic impact of regulating the transaction. The Department's
proposal for the ammonium nitrate definition was informed by public
comment received from the ANPRM; consultation with the Federal Bureau
of Investigation's (FBI) Explosives Unit and a variety of other
Federal, State, and private sector entities; and on a review of
detonability studies available at the time the NPRM was published.
After reviewing the public input received through the notice and
comment process on the proposed definition of ammonium nitrate, DHS
determined that it was appropriate to seek additional scientific data
on the
[[Page 25496]]
feasibility of weaponizing commercially available products containing
ammonium nitrate before establishing a threshold percentage and
quantity of ammonium nitrate that would be subject to regulation. DHS
entered into an interagency agreement with the Department of Energy
(DOE) on July 12, 2012 to obtain the technical expertise of Sandia
National Laboratories (SNL) and to perform testing and collect data on
the feasibility of weaponizing commercially available products,
chemicals, and mixtures containing ammonium nitrate. The Department
initiated this activity to inform both the Ammonium Nitrate Security
Program rulemaking and other DHS bombing prevention and chemical
security initiatives.
SNL performed a literature review to determine areas in need of
technical assessments. SNL then designed technical assessments to
determine the effects of total mass, physical form, and dilution on the
detonability of ammonium nitrate mixtures using materials and under
conditions realistic to terrorism bomb design or otherwise favorable to
support detonation. SNL's technical assessments and results were
reviewed on two occasions by a panel of subject matter experts, which
included Federal employees from the Department of Homeland Security,
the Department of Justice, the Department of Defense, the Department of
State, and the Office of the Director of National Intelligence. SNL
then produced a final technical report detailing the technical
assessment test plans, performance, data, and a summary of the review
and assessment of technical data performed by the panel.
The SNL test results showed that formulations of ammonium nitrate
and pre-fabricated ammonium nitrate mixtures with various fuels would
detonate with one pound of ammonium nitrate, the lowest mass tested.
The results also showed that a minimum concentration level of 15%
ammonium nitrate diluted with dolomite in a mixture containing a fuel
detonated and that dilutions of ammonium sulfate detonated at a
concentration level of 25% ammonium nitrate. When presented with the
results of the testing, the panel of subject matter experts concluded
that mixtures containing one pound of ammonium nitrate were detonable
on the test diagnostics and that a minimum detonable level of 10%
ammonium nitrate by weight could be technically defended, providing a
small margin of safety beyond the 15% level, which showed a weak
detonation.
The Department believes that release of SNL's final report will
provide important information to those who manufacture, store, process,
or engage in other transactions involving ammonium nitrate. The
Department is releasing SNL's final report in a redacted format to
protect information that could reasonably be expected to harm national
security and/or endanger individuals' lives or physical safety because
it could allow adversaries to develop effective, optimized improvised
explosive devices (IEDs).
Public Participation
As noted, the SNL technical report was developed to contribute to
the Department's body of knowledge on the detonability of ammonium
nitrate and to inform the rulemaking process. The Department is
therefore adding the report to the public docket for the proposed rule
and is requesting comment from the public on the report and its
potential application to the proposed definition of ammonium nitrate.
The Department is specifically requesting comment on the scientific
methodology and test plans SNL employed, technical data generated by
SNL and test results, and factors affecting detonability thresholds.
The Department would also like comment on the appropriateness of the
proposed ammonium nitrate definition in light of the newly available
evidence in the report, such as whether the report supports changes to
the proposed mixture and weight thresholds, and the potential economic
impacts of any changes to the proposed definition.
Comments that will provide the most assistance to the Department
will refer to a specific section, appendix, figure, and/or table of the
technical report, explain the reason for any comments, and include
other information or authority that supports such comments.
This Notice is issued under the authority of 6 U.S.C. 488a.
