vicinity of interim storage sites and transportation arteries and hubs.
Additionally, as explained in the above discussion of NEPA, PHMSA
expects that its proposed HMR amendments will yield modest GHG
emissions reductions, thereby reducing the risks posed by anthropogenic
climate change to minority, low-income, underserved, and other
disadvantaged populations and communities.
    PHMSA solicits comment from minority, low-income, underserved, and
other disadvantaged populations and communities on potential impacts of
the proposed rulemaking.

K. Privacy Act

    In accordance with 5 U.S.C. 553(c), DOT solicits comments from the
public to better inform its rulemaking process. DOT posts these
comments, without edit, including any personal information the
commenter provides, to www.regulations.gov, as described in the system
of records notice (DOT/ALL-14 FDMS). DOT's complete Privacy Act
Statement is in the Federal Register published on April 11, 2000,\43\
or on DOT's website at http://www.dot.gov/privacy.

L. Executive Order 13609 and International Trade Analysis

    Executive Order 13609 (``Promoting International Regulatory
Cooperation'') \44\ requires that agencies consider whether the impacts
associated with significant variations between domestic and
international regulatory approaches are unnecessary or may impair the
ability of American business to export and compete internationally. In
meeting shared challenges involving health, safety, labor, security,
environmental, and other issues, international regulatory cooperation
can identify approaches that are at least as protective as those that
are or would be adopted in the absence of such cooperation.
International regulatory cooperation can also reduce, eliminate, or
prevent unnecessary differences in regulatory requirements.
---------------------------------------------------------------------------

    \44\ 77 FR 26413 (May. 4, 2012).
---------------------------------------------------------------------------

    Similarly, the Trade Agreements Act of 1979 (Pub. L. 96-39), as
amended by the Uruguay Round Agreements Act (Pub. L. 103-465) (as
amended, the Trade Agreements Act), prohibits agencies from
establishing any standards or engaging in related activities that
create unnecessary obstacles to the foreign commerce of the United
States. Pursuant to the Trade Agreements Act, the establishment of
standards is not considered an unnecessary obstacle to the foreign
commerce of the United States, so long as the standards have a
legitimate domestic objective, such as providing for safety, and do not
operate to exclude imports that meet this objective. The statute also
requires consideration of international standards and, where
appropriate, that they be the basis for U.S. standards.
    PHMSA participates in the establishment of international standards
to protect the safety of the American public, and it has assessed the
effects of the proposed rule to ensure that it does not cause
unnecessary obstacles to foreign trade. In fact, the proposed rule is
expected to facilitate international trade by harmonizing U.S. and
international requirements for the transportation of hazardous
materials so as to reduce regulatory burdens and minimize delays
arising from having to comply with divergent regulatory requirements.
Accordingly, this rulemaking is consistent with Executive Order 13609
and PHMSA's obligations under the Trade Agreements Act.

M. National Technology Transfer and Advancement Act

    The NTTAA directs federal agencies to use voluntary consensus
standards in their regulatory activities unless doing so would be
inconsistent with applicable law or otherwise impractical. Voluntary
consensus standards are technical standards (e.g., specification of
materials, test methods, or performance requirements) that are
developed or adopted by voluntary consensus standard bodies. This
rulemaking involves multiple voluntary consensus standards which are
discussed at length in the discussion on Sec.  171.7. See Section 171.7
of the Section-by-Section Review for further details.

N. Executive Order 13211

    Executive Order 13211 (``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use'') \45\
requires Federal agencies to prepare a Statement of Energy Effects for
any ``significant energy action.'' Executive Order 13211 defines a
``significant energy action'' as any action by an agency (normally
published in the Federal Register) that promulgates, or is expected to
lead to the promulgation of, a final rule or regulation that (1)(i) is
a significant regulatory action under Executive Order 12866 or any
successor order and (ii) is likely to have a significant adverse effect
on the supply, distribution, or use of energy (including a shortfall in
supply, price increases, and increased use of foreign supplies); or (2)
is designated by the Administrator of the Office of Information and
Regulatory Affairs (OIRA) as a significant energy action.
---------------------------------------------------------------------------

    \45\ 66 FR 28355 (May 22, 2001).
---------------------------------------------------------------------------

    This proposed rule is not a significant action under Executive
Order 12866, nor is it expected to have an annual effect on the economy
of $100 million. Further, this action is not expected to have a
significant adverse effect on the supply, distribution, or use of
energy in the United States. The Administrator of OIRA has not
designated the proposed rule as a significant energy action. For
additional discussion of the anticipated economic impact of this
rulemaking, please review the PRIA posted in the rulemaking docket.

    (a) * * *
    (1) Division 6.2 (Infectious substance) means a material known or
reasonably expected to contain a pathogen. A pathogen is a
microorganism (including bacteria, viruses, parasites, and fungi) or
other agent, such as a proteinaceous infectious particle (prion) that
can cause disease in humans or animals. An infectious substance must be
assigned the identification number UN2814, UN2900, UN3291, UN3373, or
UN3549 as appropriate, and must be assigned to one of the following
categories:
    (i) Category A: An infectious substance in a form capable of
causing permanent disability or life-threatening or fatal disease in
otherwise healthy humans or animals when exposure to it occurs. An
exposure occurs when an infectious substance is released outside of its
protective packaging, resulting in physical contact with humans or

animals. A Category A infectious substance must be assigned to
identification number UN2814, UN2900, or UN3549, as appropriate.
Assignment to UN2814, UN2900, or UN3549 must be based on the known
medical history or symptoms of the source patient or animal, endemic
local conditions, or professional judgment concerning the individual
circumstances of the source human or animal.
    (ii) Category B: An infectious substance that is not in a form
generally capable of causing permanent disability or life-threatening
or fatal disease in otherwise healthy humans or animals when exposure
to it occurs. This includes Category B infectious substances
transported for diagnostic or investigational purposes. A Category B
infectious substance must be described as ``Biological substance,
Category B'' and assigned identification number UN3373. This does not
include regulated medical waste, which must be assigned identification
number UN3291.
* * * * *
    (5) Regulated medical waste or clinical waste or (bio) medical
waste means a waste or reusable material derived from the medical
treatment of an animal or human, which includes diagnosis and
immunization, or from biomedical research, which includes the
production and testing of biological products. Regulated medical waste
or clinical waste or (bio) medical waste containing a Category A
infectious substance must be classed as an infectious substance, and
assigned to UN2814, UN2900, or UN3549, as appropriate.

the Sec.  172.101 Table. When the Sec.  172.101 Table provides more
than one packing group for a Class 8 material, the packing group must
be determined using data obtained from tests conducted in accordance
with the OECD Guidelines for the Testing of Chemicals, Test No. 435,
``In Vitro Membrane Barrier Test Method for Skin Corrosion'' (IBR, see
Sec.  171.7 of this subchapter) or Test No. 404, ``Acute Dermal
Irritation/Corrosion'' (IBR, see Sec.  171.7 of this subchapter). A
material that is determined not to be corrosive in accordance with OECD
Guideline for the Testing of Chemicals, Test No. 430, ``In Vitro Skin
Corrosion: Transcutaneous Electrical Resistance Test (TER)'' (IBR, see
Sec.  171.7 of this subchapter) or Test No. 431, ``In Vitro Skin
Corrosion: Reconstructed Human Epidermis (RHE) Test Method'' (IBR, see
Sec.  171.7 of this subchapter) may be considered not to be corrosive
to human skin for the purposes of this subchapter without further
testing. However, a material determined to be corrosive in accordance
with Test No. 430 or Test No. 431 must be further tested using Test No.
435 or Test No. 404. If the in vitro test results indicate that the
substance or mixture is corrosive, but the test method does not clearly
distinguish between assignment of packing groups II and III, the
material may be considered to be in packing group II without further
testing. The packing group assignment using data obtained from tests
conducted in accordance with OECD Guideline Test No. 404 or Test No.
435 must be as follows:

    (A) To determine the total required capacity of the relief devices,
which must be regarded as being the sum of the individual capacities of
all the contributing devices, the following formula must be used:
[GRAPHIC] [TIFF OMITTED] TP10AU21.025

Where:

Q = minimum required rate of discharge in cubic meters of air per
second (\m\\3\/s) at conditions: 1 bar and 0 [deg]C (273
[deg]K);
F = for uninsulated shells: 1; for insulated shells: U(649-t)/13.6
but in no case, is less than 0.25

Where:

U = heat transfer coefficient of the insulation, in kW
m-\2\K-\1\, at 38 [deg]C (100 [deg]F); and t =
actual temperature of the hazardous material during filling (in
[deg]C) or when this temperature is unknown, let t = 15 [deg]C (59
[deg]F). The value of F given in this paragraph (i)(2)(i)(A) for
insulated shells may only be used if the insulation is in
conformance with paragraph (i)(2)(iv) of this section;
A = total external surface area of shell in square meters;
Z = the gas compressibility factor in the accumulating condition
(when this factor is unknown, let Z equal 1.0);
T = absolute temperature in Kelvin ([deg]C + 273) above the pressure
relief devices in the accumulating condition;
L = the latent heat of vaporization of the liquid, in kJ/kg, in the
accumulating condition;

M = molecular weight of the hazardous material.
