SUPPLEMENTARY INFORMATION:
I. Introduction
Waste Control Specialists, LLC (WCS), operates a facility in
Andrews County, Texas, that is licensed to process and store certain
types of radioactive material contained in low-level waste (LLW) and
mixed waste (MW). The facility also disposes of hazardous and toxic
waste. Under an Agreement authorized by the Atomic Energy Act, as
amended (AEA), the NRC can relinquish and a State can assume,
regulatory authority over radioactive material specified in an
Agreement with NRC. In 1963, Texas entered into an Agreement and
assumed regulatory authority over source, byproduct and SNM less than a
critical mass.
On November 30, 1997, the State of Texas Department of Health (TDH)
issued WCS a radioactive materials license (RML) to possess, treat, and
store LLW (RML R04971). In 1997, WCS began accepting Resource
Conservation and Recovery Act (RCRA) and Toxic Substance Control Act
(TSCA) wastes for treatment, storage, and disposal. Later that year,
WCS received a license from the TDH for treatment and storage of MW and
LLW. The MW and LLW streams may contain quantities of SNM. In 2007,
regulatory responsibility for RML R04971 was transferred by TDH to the
Texas Commission on Environmental Quality (TCEQ). In September 2009,
the TCEQ issued RML R04100 to WCS for disposal of LLW.
Section 70.3 of Title 10, Code of Federal Regulations (10 CFR) part
70 requires persons who own, acquire, deliver, receive, possess, use,
or transfer SNM to obtain a license pursuant to the requirements of 10
CFR part 70. The licensing requirements in 10 CFR part 70 apply to
persons in Agreement States possessing greater than critical mass
quantities, as defined in 10 CFR 150.11. However, pursuant to 10 CFR
70.17(a), ``the Commission may grant such exemptions from the
requirements of the regulations in this part as it determines are
authorized by law and will not endanger life or property or the common
defense and security and are otherwise in the public interest.''
In September 2000, WCS submitted to NRC an exemption request from
the licensing requirements in 10 CFR part 70. On November 21, 2001, the
NRC issued an Order to WCS (2001 Order) granting an exemption to WCS
from certain NRC regulations and permitted WCS, under specified
conditions, to possess waste containing SNM in greater quantities than
specified in 10 CFR part 150, at the WCS storage and treatment facility
in Andrews County, Texas, without obtaining an NRC license pursuant to
10 CFR part 70. The 2001 NRC Order was published in the Federal
Register on November 15, 2001 (66 FR 57489). As seen in the attachments
to the November 21, 2001, NRC letter to WCS (ADAMS Accession No.
ML030130085), the conditions specified in the 2001 Order are discussed
in the October 2001 Environmental Assessment (EA) and November 2001
Safety Evaluation Report (SER) that supported the 2001 Order.
By letters dated August 6, 2003, and March 14, 2004, WCS requested
a modification to the 2001 Order, which would allow it to use
additional reagents for chemical stabilization of mixed waste
containing SNM. The NRC issued the new Order on November 4, 2004 (2004
Order), which superseded the 2001 Order. The 2004 Order was published
in the Federal Register on November 12, 2004 (69 FR 65468). The new
conditions specified in the 2004 Order are discussed in the October
2004 EA (ADAMS Accession No. ML043020614) and SER (ADAMS Accession No.
ML042250362) that supported the 2004 Order. The 2004 Order changed the
2001 Order Conditions to allow WCS to use such chemical reagents as it
deems necessary for treatment and stabilization of mixed waste
containing SNM, provided that the SNM mass does not exceed specified
concentration limits.
By letter dated December 10, 2007, WCS requested additional
modifications to the 2004 Order. The NRC issued the new Order to WCS on
October 20, 2009 (2009 Order), which superseded the 2004 Order. The
2009 Order was published in the Federal Register on October 26, 2009
(74 FR 55072). The new conditions specified in the 2009 Order are
discussed in the October 2009 EA (ADAMS Accession No. ML092460509) and
SER (ADAMS Accession No. ML093070307) that supported the 2009 Order.
The 2009 Order changed the 2004 Order Conditions regarding sampling of
waste, what is allowed to be in the waste, and the amount of highly
water soluble SNM in each waste package.
In July 2013, by Amendment No. 22 of RML R04100, the TCEQ began to
merge the license requirements in RML R04971 (for the radioactive waste
treatment, storage, and processing facility) with the requirements in
RML R04100 (for the LLW land disposal facility). In Amendment No. 22 of
RML R04100, the TCEQ license requirements related to the NRC 2009 Order
in RML R04971 for the WCS treatment, storage, and processing facility
were transferred to RML R04100. Previous Orders referred to that
location as the treatment, storage, and processing facility.
Subsequently, WCS began referring to that location as the ``Treatment,
Storage and Disposal Facility.'' The NRC will use the name ``Treatment,
Storage, and Disposal Facility'' and the abbreviation TSDF to reference
that location in this Order.
The previous NRC Orders (2001, 2004, and 2009) addressed the issue
that 10 CFR 70.3 requires persons who own, acquire, deliver, receive,
possess, use, or transfer SNM to obtain an NRC license pursuant to the
requirements in 10 CFR part 70. However, 10 CFR 150.10 exempts a person
in an Agreement State who possesses SNM in quantities not sufficient to
form a critical mass from the NRC's imposed licensing requirements and
regulations. The method for calculating the quantity of SNM not
sufficient to form a critical mass is set out in 10 CFR 150.11.
Therefore, prior to the NRC 2001 Order, WCS was required to comply with
NRC regulatory requirements and obtain an NRC specific license to
possess SNM in quantities greater than amounts established in 10 CFR
150.11. The 2001 WCS exemption request to NRC proposed to use
concentration-based limits rather than mass-based limits at a specific
location at the WCS facility. The NRC 2001 Order granted, and the
subsequent NRC Orders (2004 and 2009) continued, the use of
concentration-based limits with conditions at a specific location at
the WCS facility. The TCEQ incorporated the concentration-based limits
and conditions from each respective NRC Order (2001, 2004, and 2009)
into the WCS license for the specific location at the WCS facility
where the concentration-based limits instead of mass-based limits are
applicable.
By letter dated July 18, 2014 (ADAMS Accession No. ML14209A660),
WCS requested an exemption from NRC regulations to possess SNM in
excess of
[[Page 73649]]
the critical mass limits specified in 10 CFR 150.11 while temporarily
storing specific waste at a different location at the WCS facility
other than the TSDF. The WCS exemption request referenced the WCS June
20, 2014, letter to the NRC (ADAMS Accession No. ML14171A554) that
notified the NRC of actions that WCS had taken in response to the on-
going U.S. Department of Energy (DOE) investigation of an unplanned
radiation release event at the DOE Waste Isolation Pilot Plant (WIPP)
facility (i.e., the WIPP incident). The specific waste includes some of
the transuranic waste that originated at the DOE Los Alamos National
Laboratory (LANL), which are destined to be disposed of at the DOE WIPP
facility (i.e., LANL waste). Due to the February 14, 2014, WIPP
incident, the DOE suspended operations at the WIPP facility. In April
2014, WCS began receiving some of the LANL waste from DOE, which met
the conditions in the NRC 2009 Order. WCS intended to temporarily store
the LANL waste at the TSDF at the WCS facility until WCS ships the
waste.
Based on the DOE investigation of the WIPP incident, DOE
subsequently informed WCS that some of the LANL waste being temporarily
stored at the WCS TSDF could, under certain conditions, react and
potentially result in a release of transuranic radionuclides to the
environment. On June 12, 2014, WCS responded to DOE's information by
starting to voluntarily move the identified LANL waste to the Federal
Waste Disposal Facility (FWF) at the WCS facility for temporary
storage.
After evaluating WCS's exemption request, the NRC staff decided
that the appropriate action is to grant the request, contingent on
compliance with the additional conditions contained in the 2014 Order.
The reasons for this decision are further described in the SER for this
request (ADAMS Accession No. ML14230A804).
II. Conditions
Currently, WCS is exempted from the requirements of 10 CFR part 70,
including the requirements for an NRC license in 10 CFR 70.3. This
Order supersedes the 2009 Order that applies to the WCS treatment,
storage and processing facility. Previous Orders referred to that
location as the treatment, storage, and processing facility.
Subsequently, WCS began referring to that location as the ``Treatment,
Storage and Disposal Facility.'' The NRC will use the name ``Treatment,
Storage, and Disposal Facility'' and the abbreviation TSDF to reference
that location in the 2014 Order.
The NRC reviewed the information in the WCS request and, along with
clarifying teleconference calls and other public and non-public
information provided by WCS, the NRC decided that the appropriate
action is to grant the WCS exemption request, but has modified WCS'
exemption request to include additional conditions which are reflected
in this 2014 Order. As described in the SER Report for this request,
the NRC has determined that the modified conditions in the 2014 Order
will not endanger life or property or the common defense and security
and is otherwise in the public interest to allow for movement and the
temporary storage of the identified LANL waste at WCS FWF.
Conditions 1 through 7 remain the same as in the 2009 Order. A new
Condition 8 was created in this 2014 Order to address the NRC's
modification of WCS' exemption request. The new Condition 8 applies to
the LANL waste stored at either the TSDF or the FWF. Condition 8 in the
2009 Order was renumbered as Condition 9 in this 2014 Order. Condition
9 in the 2009 Order is renumbered as Condition 10 in this 2014 Order. A
new Condition 11 was created in this 2014 Order. As such, Conditions 1
through 11 of this 2014 Order now read as the following:
1. Concentrations of SNM in individual waste containers and/or
during processing shall not exceed the following values:
------------------------------------------------------------------------
Operational Measurement
limit (gram uncertainty
SNM isotope SNM/gram (gram SNM/gram
waste) waste)
------------------------------------------------------------------------
U-233................................... 4.7E-04 7.1E-05
U-235 (10 percent enriched)............. 9.9E-04 1.5E-04
U-235 (100 percent enriched)............ 6.2E-04 9.3E-05
Pu-239.................................. 2.8E-04 4.2E-05
Pu-241.................................. 2.2E-04 3.2E-05
------------------------------------------------------------------------
When mixtures of these SNM isotopes are present in the waste, the
sum-of-the-fractions rule, as illustrated below, shall be used.
[GRAPHIC] [TIFF OMITTED] TN11DE14.028
The measurement uncertainty values in column 3 above represent the
maximum one-sigma uncertainty associated with the measurement of the
concentration of the particular radionuclide.
The SNM must be uniformly distributed throughout the waste, such
that the limiting concentrations must not be exceeded on average in any
contiguous mass of 600 kilograms.
2. The mass concentration of carbon, fluorine, and bismuth in the
waste must be limited as follows:
------------------------------------------------------------------------
Carbon Fluorine Bismuth
SNM isotope wt % wt % wt %
------------------------------------------------------------------------
U-233..................................... 28 34 34
U-235(10)................................. 25 35 31
U-235(100)................................ 41 42 33
Pu-239.................................... 43 43 34
Pu-241.................................... 37 39 32
------------------------------------------------------------------------
For waste containing mixtures of C, F, and Bi, the sum of the
weight fractions of C, F, and Bi shall be compared to the most
restrictive maximum allowable weight fractions for any one of those
elements. Similarly, where mixtures of radionuclides are present in the
waste, the limiting maximum allowable weight fraction of C, F, and Bi
shall be applied. The presence of the above materials will be
determined and documented by the
[[Page 73650]]
generator, based on process knowledge or testing.
3. Waste accepted shall not contain total quantities of beryllium,
hydrogenous material enriched in deuterium, or graphite above one tenth
of one percent of the total weight of the waste. The presence of the
above materials will be determined and documented by the generator,
based on process knowledge, or testing.
4. Possession of highly water soluble forms of SNM shall not exceed
the amount of SNM of low strategic significance defined in 10 CFR 73.2.
Highly soluble forms of SNM include, but are not limited to: Uranium
sulfate, uranyl acetate, uranyl chloride, uranyl formate, uranyl
fluoride, uranyl nitrate, uranyl potassium carbonate, uranyl sulfate,
plutonium chloride, plutonium fluoride, and plutonium nitrate. The
presence of the above materials will be determined and documented by
the generator, based on process knowledge or testing.
5. Processing of mixed waste containing SNM will be limited to
chemical stabilization (i.e., mixing waste with reagents). For batches
with more than 600 kilograms of waste, the total mass of SNM shall not
exceed the concentration limits in Condition 1 times 600 kilograms of
waste.
6. Prior to shipment of waste, WCS shall require generators to
provide a written certification containing the following information
for each waste stream:
a. Waste Description. The description must detail how the waste was
generated, list the physical forms in the waste, and identify uranium
chemical composition.
Waste Characterization Summary. The data must include a general
description of how the waste was characterized (including the
volumetric extent of the waste, and the number, location, type, and
results of any analytical testing), the range of SNM concentrations,
and the analytical results with error values used to develop the
concentration ranges.
b. Uniformity Description. A description of the process by which
the waste was generated showing that the spatial distribution of SNM is
homogeneous or other information supporting spatial homogeneity.
c. Manifest Concentration. The generator must describe the methods
to be used to determine the concentrations on the manifests. These
methods could include direct measurement and the use of scaling
factors. The generator must describe the uncertainty associated with
sampling and testing used to obtain the manifest concentrations.
WCS shall review the above information and, if adequate, approve in
writing this pre-shipment waste characterization and assurance plan
before permitting the shipment of a waste stream. This will include
statements that WCS has a written copy of all the information required
above, that the characterization information is adequate and consistent
with the waste description, and that the information is sufficient to
demonstrate compliance with Conditions 1 through 4. Where generator
process knowledge is used to demonstrate compliance with Conditions 1,
2, 3, or 4, WCS shall review this information and determine when
testing is required to provide additional information in assuring
compliance with the Conditions. WCS shall retain this information as
required by the State of Texas to permit independent review.
At the time waste is received, WCS shall require generators of SNM
waste to provide a written certification with each waste manifest that
states that the SNM concentrations reported on the manifest do not
exceed the limits in Condition 1, and that the waste meets Conditions 2
through 4.
WCS shall require generators to sample and determine the SNM
concentration for each waste stream, not to include sealed sources, at
a frequency of once per 600 kg if the concentrations are above one
tenth the SNM limits of Condition 1. The measurement uncertainty shall
not exceed the uncertainty value in Condition 1 and shall be provided
on the written certification.
7. WCS shall sample and determine the SNM concentration for each
waste stream, not to include sealed sources, at a frequency of once per
600 kg if the concentrations are above one tenth the SNM limits of
Condition 1. This confirmatory testing is not required for waste to be
disposed of at DOE's WIPP facility.
8. The ``WIPP incident'' is the February 14, 2014, unplanned
radiation release event at the DOE WIPP facility in New Mexico. The
following relate to WCS storing DOE transuranic waste that originated
at the LANL, which are destined to be disposed of at the DOE WIPP
facility (i.e., ``LANL waste''), at either the WCS Treatment, Storage,
and Disposal Facility (TSDF) or the WCS Federal Waste Disposal Facility
(FWF):
A. The following conditions are applicable to LANL waste stored at
the Federal Waste Disposal Facility (FWF) and other SNM bearing waste
stored or disposed of at the FWF:
1. The following waste is allowed to be stored at the WCS FWF: LANL
waste in accordance with the concentration-based limits specified in
Conditions 1 through 7, provided that it is in Standardized Waste Boxes
(SWBs) analyzed to be safe in the DOE ``Nuclear Critical Safety
Evaluation,'' WIPP-016, Rev. 4. The lids of the SWBs shall be bolted or
similarly secured to the body and the SWBs shall be placed inside
Modular Concrete Canisters (MCCs) consistent with the configurations
analyzed in WIPP-016.
2. The LANL waste shall be isolated from other SNM-bearing waste by
a minimum of 6.096 meters (20 feet).
3. The LANL waste in MCCs shall be stacked no more than one MCC
high.
B. The following conditions are applicable to all the LANL waste
stored at either the TSDF or the FWF:
1. WCS shall follow the general reporting and recordkeeping
requirements of 10 CFR part 73 that are applicable to those who possess
SNM of 1 gram or more. Those requirements are:
(1) Notification to the NRC within 1 hour of discovery of any
unauthorized removal of SNM which WCS is authorized to possess; and
(2) maintenance of a recordkeeping program showing the receipt,
inventory, acquisition, transfer, and disposal of all SNM in WCS'
possession.
2. The contents and matrices of the LANL waste in the inner
containers shall conform to the description in the WCS non-public
information.
3. The physical security plan for the LANL waste shall be
maintained to specifically include detection, assessment, and response
methods and procedures for the LANL waste for as long as the LANL waste
is at the WCS facility.
4. WCS is allowed to possess the LANL waste for a maximum of 2
years.
5. The LANL waste shall remain unopened in the inner container in
which it was shipped, unless WCS needs to take an action on one of the
inner containers based on knowledge from DOE's investigation of the
WIPP incident. Only one inner container may be open at a time.
6. WCS shall keep NRC informed of the status of the DOE
investigation of the WIPP incident. If DOE determines that some of LANL
waste at WCS was similar to the waste that DOE determines to have
contributed to the WIPP incident, then WCS will notify the NRC.
9. WCS shall notify the NRC, Region IV office within 24 hours if
any of the above Conditions are violated. A written notification of the
event must be provided within 7 days.
[[Page 73651]]
10. WCS shall obtain NRC's approval prior to changing any
activities associated with the above Conditions.
11. The Director of the Office of Nuclear Material Safety and
Safeguards (or designee), may, in writing, relax or rescind any of the
above conditions upon demonstration by WCS of good cause.
III. Conclusion
Based on the staff's evaluation, the NRC has determined, pursuant
to 10 CFR 70.17(a), that the exemption as described above at the WCS
facility is authorized by law, will not endanger life or property or
the common defense and security and is otherwise in the public
interest. Accordingly, by this Order, the NRC hereby grants this
exemption subject to the conditions in this Order, which implements
concentration-based limits for SNM quantities not sufficient to form a
critical mass at specific locations at the WCS facility. This NRC Order
is effective and final 20 days after issuance of the Order without
further order or proceedings. This NRC's Order enables the State of
Texas to regulate SNM materials at the WCS facility under the State's
radiation protection program as long as WCS complies with this Order.
Pursuant to the requirements in 10 CFR part 51, the Commission has
published an Environmental Assessment for the proposed action wherein
it has determined that the granting of this exemption will have no
significant impacts on the quality of the human environment. That
finding was noticed in the Federal Register on November 6, 2014 (79 FR
65999).
Dated at Rockville, Maryland, this 3rd day December 2014.
