The NRC
has terminated License No. STB–401,
held by Mallinckrodt LLC
(Mallinckrodt), for a site in St. Louis,
Missouri and has approved the site for
unrestricted release.
In 1961, Mallinckrodt received
License No. STB–401 to extract
columbium and tantalum from natural
ores and tin slags. In July 1993, the NRC
amended Mallinckrodt’s license to a
possession only license for the purpose
of decommissioning and license
termination. The contamination at the
site was due to licensed activities
consisted of natural uranium, natural
thorium, and their associated progeny.
The Mallinckrodt site is a 43 acre site
subdivided into ten areas called Plants.
The former Columbium-Tantalum (C–T)
process areas included 21 support
buildings on approximately 4.2 acres,
primarily located within Plant 5, but
also in portions of Plants 1, 3, 6, 7, and
8.
In addition to the C–T activities
conducted under License No. STB–401,
the Mallinckrodt site was previously
used for Manhattan Engineer District/
Atomic Energy Commission (MED/AEC)
activities. The U.S. Army Corps of
Engineers (USACE) is responsible for
remediating these portions of the site
under the Formerly Utilized Sites
Remedial Action Program (FUSRAP).
Mallinckrodt decommissioned the
C–T project areas of the site in two
phases. In Phase I, Mallinckrodt
decommissioned the buildings and
equipment to the extent necessary to
meet the NRC’s guidelines for
unrestricted release in § 20.1402 of title
10 of the Code of Federal Regulations
(10 CFR). Phase I of the
decommissioning project was
completed in February 2007 (ADAMS
Accession No. ML070530675).
Following Phase I decommissioning,
the C–T areas remaining for remediation
were limited to the soil, pavement, and
sewers in Plant 5, as well as portions of
Plant 6 and 7. Mallinckrodt’s Phase II
Decommissioning Plan (DP) (ADAMS
Accession Nos. ML083150652 and
ML101620140) described Mallinckrodt’s
plan for decommissioning the
remainder of the C–T project areas to
meet the criteria for unrestricted release,
though the remediation of portions of
Plants 6 and 7 was not included in the
DP and was addressed separately, as is
mstockstill on DSK4VPTVN1PROD with NOTICES
SUPPLEMENTARY INFORMATION:
VerDate Sep<11>2014

described below. The NRC approved
Mallinckrodt’s Phase II DP on July 1,
2010 (ADAMS Accession No.
ML091960063).
Plants 6 and 7 contained residual
contamination from both licensed
activities and MED/AEC activities. The
MED/AEC activities in Plants 6 and 7
resulted in contamination in buildings
and soil in these plants. Additionally, in
Plant 6, approximately 300 cubic yards
of unreacted ore (URO) generated as part
of the C–T process was buried in 10
trenches in 1972 and 1973. Plant 7
contained sewers, a grit chamber, and
two wastewater neutralization basins
that were used to support C–T
operations.
Mallinckrodt and the USACE entered
into two agreements to delineate
remediation responsibilities in Plants 6
and 7. Mallinckrodt’s responsibilities
included the removal of the buried URO
in Plant 6 and the removal of the grit
chamber in Plant 7. On February 9,
2015, USACE provided Mallinckrodt
with a letter acknowledging that
Mallinckrodt had completed the
removal of the URO and grit chambers
and stating that the USACE was
proceeding with remediation of these
areas under FUSRAP (ADAMS
Accession No. ML15090A705).
Mallinckrodt’s Phase II DP requested
that the NRC terminate its license in
accordance with 10 CFR 20.1402
without accounting for MED/AEC
contamination in demonstrating
compliance with the dose limits in
§ 20.1402. In its approval of the Phase
II DP, the NRC exempted the MED/AEC
material from consideration in
demonstrating compliance with license
termination requirements (ADAMS
Accession No. ML091960087). The basis
for granting the exemption was: (1)
Mallinckrodt will meet 25 mrem/year
unrestricted release criteria for C–T
process areas; and (2) unlicensed MED/
AEC material is being remediated to the
NRC’s unrestricted release standards of
25 mrem/year by USACE. The dose from
the residual radioactivity at the site is
primarily from the direct radiation
pathway, therefore the NRC concluded
that an individual would not
simultaneously receive a dose from both
areas. The staff, therefore, concluded
that it is reasonable to terminate License
STB–401 after Mallinckrodt completes
decommissioning activities in the C–T
process areas and demonstrates that the
C–T process areas at the site meet the
NRC’s unrestricted release criteria.
This finding is based in part on
USACE’s commitment to remediate the
site under FUSRAP. At the time,
Mallinckrodt and USACE had reached
an agreement regarding delineation of
PO 00000
Frm 00085
Fmt 4703
Sfmt 4703
8257
responsibility for remediating Plant 6,
but had not yet agreed on the
delineation of responsibility for Plant 7.
Therefore, the exemption was
conditioned on Mallinckrodt and
USACE reaching a delineation
agreement for Plant 7 before
decommissioning was complete.
Mallinckrodt and USACE entered into a
delineation agreement for Plant 7 on
October 31, 2014 (cover letter available
at ADAMS Accession No.
ML15041A076).
Mallinckrodt performed remediation
of the C–T project areas based on their
Phase II DP, conducted a Final Status
Survey (FSS) and provided the NRC
with a Final Status Survey Report
(FSSR) documenting the residual
radioactivity remaining on site for
which Mallinckrodt was responsible
(ADAMS Accession No. ML14177A180).
Mallinckrodt subsequently provided
additional information in response to
the NRC’s requests for additional
information (ADAMS Accession Nos.
ML14339A278, ML15177A051, and
ML15334A417). On February 12, 2015,
Mallinckrodt submitted a license
amendment application requesting the
use of the dose assessment approach, as
well as the derived concentration
guideline level (DCGL) approach
(ADAMS Accession No. ML15063A404).
The NRC approved this license
amendment request on February 4, 2016
(ADAMS Accession No. ML15286A174).
The NRC has now completed its
review of the FSSR and associated
documents according to NUREG–1757,
‘‘Consolidated Decommissioning
Guidance,’’ and guidance in the MultiAgency Radiation Survey and Site
Investigation Manual (MARSSIM)
(NUREG 1575). The NRC staff has
concluded that the FSS design and data
collected were adequate to characterize
the residual radioactivity in the portions
of the Mallinckrodt site where NRC
regulated activities took place. The NRC
staff also concluded that the data
analysis and dose assessments
performed are appropriate and that the
projected dose from residual
radioactivity in these areas is less than
the 25 mrem/year dose criterion in 10
CFR 20.1402. For these reasons, the
NRC staff has determined that
Mallinckrodt has demonstrated that the
site will meets the radiological criteria
for license termination described in 10
CFR part 20 subpart E and the
exemption granted by the NRC in its
approval of the Phase II DP. Therefore,
Source Materials License No. STB–401
has been terminated.

SUPPLEMENTARY INFORMATION: The NRC has terminated License No. STB-401,
held by Mallinckrodt LLC (Mallinckrodt), for a site in St. Louis,
Missouri and has approved the site for unrestricted release.
In 1961, Mallinckrodt received License No. STB-401 to extract
columbium and tantalum from natural ores and tin slags. In July 1993,
the NRC amended Mallinckrodt's license to a possession only license for
the purpose of decommissioning and license termination. The
contamination at the site was due to licensed activities consisted of
natural uranium, natural thorium, and their associated progeny. The
Mallinckrodt site is a 43 acre site subdivided into ten areas called
Plants. The former Columbium-Tantalum (C-T) process areas included 21
support buildings on approximately 4.2 acres, primarily located within
Plant 5, but also in portions of Plants 1, 3, 6, 7, and 8.
In addition to the C-T activities conducted under License No. STB-
401, the Mallinckrodt site was previously used for Manhattan Engineer
District/Atomic Energy Commission (MED/AEC) activities. The U.S. Army
Corps of Engineers (USACE) is responsible for remediating these
portions of the site under the Formerly Utilized Sites Remedial Action
Program (FUSRAP).
Mallinckrodt decommissioned the C-T project areas of the site in
two phases. In Phase I, Mallinckrodt decommissioned the buildings and
equipment to the extent necessary to meet the NRC's guidelines for
unrestricted release in Sec. 20.1402 of title 10 of the Code of
Federal Regulations (10 CFR). Phase I of the decommissioning project
was completed in February 2007 (ADAMS Accession No. ML070530675).
Following Phase I decommissioning, the C-T areas remaining for
remediation were limited to the soil, pavement, and sewers in Plant 5,
as well as portions of Plant 6 and 7. Mallinckrodt's Phase II
Decommissioning Plan (DP) (ADAMS Accession Nos. ML083150652 and
ML101620140) described Mallinckrodt's plan for decommissioning the
remainder of the C-T project areas to meet the criteria for
unrestricted release, though the remediation of portions of Plants 6
and 7 was not included in the DP and was addressed separately, as is
described below. The NRC approved Mallinckrodt's Phase II DP on July 1,
2010 (ADAMS Accession No. ML091960063).
Plants 6 and 7 contained residual contamination from both licensed
activities and MED/AEC activities. The MED/AEC activities in Plants 6
and 7 resulted in contamination in buildings and soil in these plants.
Additionally, in Plant 6, approximately 300 cubic yards of unreacted
ore (URO) generated as part of the C-T process was buried in 10
trenches in 1972 and 1973. Plant 7 contained sewers, a grit chamber,
and two wastewater neutralization basins that were used to support C-T
operations.
Mallinckrodt and the USACE entered into two agreements to delineate
remediation responsibilities in Plants 6 and 7. Mallinckrodt's
responsibilities included the removal of the buried URO in Plant 6 and
the removal of the grit chamber in Plant 7. On February 9, 2015, USACE
provided Mallinckrodt with a letter acknowledging that Mallinckrodt had
completed the removal of the URO and grit chambers and stating that the
USACE was proceeding with remediation of these areas under FUSRAP
(ADAMS Accession No. ML15090A705).
Mallinckrodt's Phase II DP requested that the NRC terminate its
license in accordance with 10 CFR 20.1402 without accounting for MED/
AEC contamination in demonstrating compliance with the dose limits in
Sec. 20.1402. In its approval of the Phase II DP, the NRC exempted the
MED/AEC material from consideration in demonstrating compliance with
license termination requirements (ADAMS Accession No. ML091960087). The
basis for granting the exemption was: (1) Mallinckrodt will meet 25
mrem/year unrestricted release criteria for C-T process areas; and (2)
unlicensed MED/AEC material is being remediated to the NRC's
unrestricted release standards of 25 mrem/year by USACE. The dose from
the residual radioactivity at the site is primarily from the direct
radiation pathway, therefore the NRC concluded that an individual would
not simultaneously receive a dose from both areas. The staff,
therefore, concluded that it is reasonable to terminate License STB-401
after Mallinckrodt completes decommissioning activities in the C-T
process areas and demonstrates that the C-T process areas at the site
meet the NRC's unrestricted release criteria.
This finding is based in part on USACE's commitment to remediate
the site under FUSRAP. At the time, Mallinckrodt and USACE had reached
an agreement regarding delineation of responsibility for remediating
Plant 6, but had not yet agreed on the delineation of responsibility
for Plant 7. Therefore, the exemption was conditioned on Mallinckrodt
and USACE reaching a delineation agreement for Plant 7 before
decommissioning was complete. Mallinckrodt and USACE entered into a
delineation agreement for Plant 7 on October 31, 2014 (cover letter
available at ADAMS Accession No. ML15041A076).
Mallinckrodt performed remediation of the C-T project areas based
on their Phase II DP, conducted a Final Status Survey (FSS) and
provided the NRC with a Final Status Survey Report (FSSR) documenting
the residual radioactivity remaining on site for which Mallinckrodt was
responsible (ADAMS Accession No. ML14177A180). Mallinckrodt
subsequently provided additional information in response to the NRC's
requests for additional information (ADAMS Accession Nos. ML14339A278,
ML15177A051, and ML15334A417). On February 12, 2015, Mallinckrodt
submitted a license amendment application requesting the use of the
dose assessment approach, as well as the derived concentration
guideline level (DCGL) approach (ADAMS Accession No. ML15063A404). The
NRC approved this license amendment request on February 4, 2016 (ADAMS
Accession No. ML15286A174).
The NRC has now completed its review of the FSSR and associated
documents according to NUREG-1757, ``Consolidated Decommissioning
Guidance,'' and guidance in the Multi-Agency Radiation Survey and Site
Investigation Manual (MARSSIM) (NUREG 1575). The NRC staff has
concluded that the FSS design and data collected were adequate to
characterize the residual radioactivity in the portions of the
Mallinckrodt site where NRC regulated activities took place. The NRC
staff also concluded that the data analysis and dose assessments
performed are appropriate and that the projected dose from residual
radioactivity in these areas is less than the 25 mrem/year dose
criterion in 10 CFR 20.1402. For these reasons, the NRC staff has
determined that Mallinckrodt has demonstrated that the site will meets
the radiological criteria for license termination described in 10 CFR
part 20 subpart E and the exemption granted by the NRC in its approval
of the Phase II DP. Therefore, Source Materials License No. STB-401 has
been terminated.
