18 AAC 85.210 - Radioactivity in effluents to uncontrolled areas
(a) Except as
authorized in
18 AAC 85.280 or in (b) of this
section, a person may not possess, use, or transfer radioactive material in a
manner that will release to an uncontrolled area radioactive material in
concentrations that exceed the limits specified in 10 C.F.R. Part 20, Appendix
B, Table 2, revised as of January 1, 2014 and adopted by reference. For
purposes of this subsection, concentrations may be averaged over a period not
greater than one year.
(b) A person
may apply to the department for proposed limits higher than those specified in
(a) of this section. The department may approve the proposed limits if the
applicant demonstrates that:
(1) the
applicant has made a reasonable effort to minimize the radioactivity contained
in effluents to uncontrolled areas; and
(2) it is not likely that radioactive
material discharge in the effluent will result in the exposure of an individual
to concentrations of radioactive material in air or water exceeding the limits
specified in 10 C.F.R. Part 20, Appendix B, Table 2, adopted by reference in
(a) of this section.
(c)
An application for higher limits pursuant to paragraph (b) of this section
shall include information demonstrating that the applicant has made a
reasonable effort to minimize the radioactivity discharged in effluents to
uncontrolled areas, and shall include, as pertinent
(1) information on flow rates, total volume
of the effluent, peak concentration of each radionuclide in the effluent, and
concentration of each radionuclide in the effluent averaged over a period of
one year at the point where the effluent leaves a stack, tube, pipe or similar
conduit;
(2) a description of the
properties of the effluents, including
(A)
chemical composition;
(B) physical
characteristics, including suspended solids content in liquid effluents, and
nature of gas or aerosol for air effluents;
(C) the hydrogen ion concentrations (pH) of
liquid effluents; and
(D) the size
range of particulates in effluents released into air;
(3) a description of the anticipated human
occupancy in the uncontrolled area where the highest concentration of
radioactive material from the effluent is expected, and, in the case of a river
or stream, a description of water uses downstream from the point of release of
the effluent;
(4) information as to
the highest concentration of each radionuclide in an uncontrolled area,
including anticipated concentrations average over a period of one year
(A) in air at any point of human occupancy;
or
(B) in water at points of use
downstream from the point of release of the effluent;
(5) the background concentration of
radionuclides in the receiving river or stream prior to the release of liquid
effluent;
(6) a description of the
environmental monitoring equipment, including sensitivity of the system, and
procedures and calculations to determine concentrations of radionuclides in the
uncontrolled area and possible reconcentrations of radionuclides; and
(7) a description of the waste treatment
facilities and procedures used to reduce the concentration of radionuclides in
effluents prior to their release.
(d) For purposes of this section, the
concentration limits in 10 C.F.R. Part 20, Appendix B, Table 2, adopted by
reference in (a) of this section, apply at the boundary of the controlled area.
The concentration of radioactive material discharged through a stack, pipe, or
similar conduit may be determined with respect to the point where the material
leaves the conduit. If the conduit discharges within the controlled area, the
concentration at the boundary may be determined by applying appropriate factors
for dilution, dispersion, or decay between the point of discharge and the
boundary.
(e) In addition to
limiting concentration in effluent streams, the department may limit quantities
of radioactive materials released in air or water during a specified period of
time if the department determines that the daily intake of radioactive material
from air, water, or food by a suitable sample of an exposed population group,
averaged over a period not exceeding one year, would otherwise exceed the daily
intake resulting from continuous exposure to air or water containing one-third
the concentration of radioactive materials specified in 10 C.F.R. Part 20,
Appendix B. Table 2, adopted by reference in (a) of this section.
(f) The provisions of this section do not
apply to disposal of radioactive material into sanitary sewerage systems, which
is governed by the provisions of
18 AAC 85.290.
