Current through Register Vol. 24-18, September 15, 2024
(1) Common and contract carriers, freight
forwarders, warehouse workers, and the U.S. Postal Service are exempt from this
chapter and chapters 246-232, 246-233, 246-235, 246-237, 246-240, 246-243, and
246-244 WAC to the extent that they transport or store radioactive material in
the regular course of their carriage for another or storage incident
thereto.
(2) Any licensee who
delivers radioactive material to a carrier for transport, where such transport
is subject to the regulations of the United States Postal Service, is exempt
from the provisions of WAC 246-231-005.
(3)
Exemption of physicians. Any
physician as defined in WAC 246-220-010 who is licensed by the department, NRC
or an agreement state, to dispense drugs in the practice of medicine, is exempt
from WAC 246-220-030 with respect to transport by the physician of licensed
material for use in the practice of medicine. However, any physician operating
under this exemption must be licensed under chapter 246-240 WAC, 10 C.F.R. 35, or the equivalent agreement state regulations.
(4)
Exemption for low-level
materials. A licensee is exempt from all requirements of this chapter
with respect to shipment or carriage of the following low-level materials:
(a) Natural material and ores containing
naturally occurring radionuclides that are either in their natural state, or
have only been processed for purposes other than for the extraction of the
radionuclides, and which are not intended to be processed for use of these
radionuclides, provided the activity concentration of the material does not
exceed 10 times the applicable radionuclide activity concentration values
specified in WAC 246-231-200, Table A-2 or Table A-3.
(b) Materials for which the activity
concentration is not greater than the activity concentration values specified
in WAC 246-231-200, Table A-2 or Table A-3, or for which the consignment
activity is not greater than the limit for an exempt consignment found in WAC
246-231-200, Table A-2 or Table A-3.
(c) Nonradioactive solid objects with
radioactive substances present on any surfaces in quantities not in excess of
the levels cited in the definition of contamination in WAC
246-231-010.
(5) A
licensee is exempt from all the requirements of this chapter, other than 10 C.F.R. 71.5 and 71.88, with respect to shipment or carriage of the following
packages, provided the packages do not contain any fissile material, or the
material is exempt from classification as fissile material in this subsection;
(a) A package that contains no more than a
Type A quantity of radioactive material;
(b) A package transported within the United
States that contains no more than 0.74 TBq (20 Ci) of special form
plutonium-244; or
(c) The package
contains only LSA or SCO radioactive material, provided:
(i) That the LSA or SCO material has an
external radiation dose of less than or equal to 10 mSv/h one rem/h), at a
distance of three meters from the unshielded material; or
(ii) That the package contains only LSA-I or
SCO-I material.
(6)
Exemption from classification as
fissile material. Fissile material meeting at least one of the
requirements in (a) through (f) of this subsection is exempt from
classification as fissile material and from the fissile material package
standards of 10 C.F.R. 71.55 and 71.59, but are subject to all other
requirements of this chapter, except as noted.
(a) Individual package containing two grams
or less fissile material.
(b)
Individual or bulk packaging containing 15 grams or less of fissile material
provided the package has at least 200 grams of solid nonfissile material for
every gram of fissile material. Lead, beryllium, graphite, and hydrogenous
material enriched in deuterium may be present in the package but must not be
included in determining the required mass for solid nonfissile
material.
(c)
(i) Low concentrations of solid fissile
material commingled with solid nonfissile material, provided that:
(A) There are at least 2000 grams of solid
nonfissile material for every gram of fissile material; and
(B) There are no more than 180 grams of
fissile material distributed within 360 kg of contiguous nonfissile
material.
(ii) Lead,
beryllium, graphite, and hydrogenous material enriched in deuterium may be
present in the package but must not be included in determining the required
mass of solid nonfissile material.
(d) Uranium enriched in uranium-235 to a
maximum of one percent by weight, and with total plutonium and uranium-233
content of up to one percent of the mass of uranium-235, provided that the mass
of any beryllium, graphite, and hydrogenous material enriched in deuterium
constitutes less than five percent of the uranium mass, and that the fissile
material is distributed homogeneously and does not form a lattice arrangement
within the package.
(e) Liquid
solutions of uranyl nitrate enriched in uranium-235 to a maximum of two percent
by mass, with a total plutonium and uranium-233 content not exceeding 0.002
percent of the mass of uranium, and with a minimum nitrogen to uranium atomic
ratio (N/U) of two. The material must be contained in at least a DOT Type A
package.
(f) Packages containing,
individually, a total plutonium mass of not more than 1000 grams, of which not
more than 20 percent by mass may consist of plutonium-239, plutonium-241, or
any combination of these radionuclides.
