SUPPLEMENTARY INFORMATION:
I. Introduction
Pursuant to 10 CFR 2.106, the Nuclear Regulatory Commission (NRC)
is providing notice in the Matter of Waste Control Specialists, LLC
(WCS) of the issuance of an order to modify WCS's exemption from the
requirements of 10 CFR part 70.
II. Further Information
I.
WCS operates a facility in Andrews County, Texas, that is currently
licensed to process and store certain types of low-level waste (LLW)
and mixed waste (MW), and dispose of hazardous and toxic waste. Texas
is an Agreement State. On November 30, 1997, this facility was licensed
by the State of Texas Department of Health (TDH) under a 10 CFR part 30
equivalent radioactive materials license to possess, treat, and store
LLW (R04971). License R04971 is currently under the jurisdiction of the
Texas Commission on Environmental Quality (TCEQ). The facility is also
licensed by the TCEQ to treat and dispose of hazardous waste. 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 TDH for
treatment and storage of MW and LLW. The MW and LLW streams may contain
quantities of special nuclear material (SNM). On May 29, 2008, the TCEQ
issued a license to WCS that authorizes WCS to receive and dispose of
byproduct material as defined in Title 25 of the Texas Administrative
Code, Section 289.260(c)(4). On January 14, 2009, the TCEQ denied
hearing requests and issued an order which allows a license to be
granted for disposal of LLW after the applicant demonstrates ownership
of all mineral rights. The order provides that a license may not be
issued, signed or granted until such demonstration is made.
Section 70.3 of 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 requested an exemption from the licensing
requirements in 10 CFR part 70. On November 21, 2001, the NRC
transmitted an Order to WCS 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 WCS's storage and treatment facility in Andrews
County, Texas, without obtaining an NRC license pursuant to 10 CFR part
70. The NRC exemption applies only to activities authorized by TCEQ
License R04971. The Order was published in the Federal Register on
November 15, 2001 (66 FR 57489). The conditions specified in the Order
are discussed in the November 2001 Safety Evaluation Report (SER) that
supported the 2001 Order.
By letters dated August 6, 2003, and March 14, 2004, Waste Control
Specialists LLC (WCS) requested an amendment to its exemption, which
would allow it to use additional reagents for chemical stabilization of
mixed waste containing SNM. The NRC transmitted the revised Order to
WCS on November 4, 2004. The Order was published in the Federal
Register on November 12, 2004 (69 FR 65468). The modified conditions
specified in the Order are discussed in the August 2004 Safety
Evaluation Report (SER) that supported the 2004 Order.
In a letter dated December 10, 2007, WCS requested additional
modifications to its exemption from certain NRC regulations relative to
the possession of SNM that is authorized by its TCEQ License R04971. By
letter dated January 22, 2008, NRC acknowledged WCS' request.
WCS' letter dated December 10, 2007, and NRC's acknowledgement
dated January 22, 2008, are available at NRC's Electronic Reading Room
at http://www.nrc.gov/reading-rm/adams.html. NRC's Agencywide Document
Access and Management System (ADAMS) is available at this Web site. The
ADAMS accession numbers for the December 10, 2007, and January 22,
2008, letters are:

December 10, 2007, WCS request for modification of the ML073550638
Order................................................
January 22, 2008, NRC acknowledgement of WCS request.. ML080150622
------------------------------------------------------------------------
II.
The NRC staff considers that the appropriate action is to grant
WCS's exemption request, with additional modifications. Currently, WCS
is exempted from the requirements of 10 CFR Part 70, including the
requirements for an NRC license in 10 CFR 70.3, for activities
authorized by TCEQ License R04971. This modification specifically would
allow WCS to: Discontinue confirmation sampling upon receipt of waste
that WCS verifies is adequately characterized by a generator to be
uniform and which contains less than one-tenth of the SNM concentration
limits presented in Condition 1; and to discontinue confirmatory
sampling requirements of Condition 7 of the Order for sealed sources.
By letter dated January 22, 2008, NRC informed WCS that it would
clarify Condition 2, which states that waste must not contain ``pure
forms'' of chemicals containing carbon, fluorine, magnesium, or bismuth
in bulk quantities. NRC is also clarifying requirements for spatial
uniformity of SNM concentrations in waste. The NRC is also revising
Condition 4 of the Order, which currently limits the amount of highly
water soluble SNM in each package, to address security concerns raised
by the NRC staff during its review. Therefore, WCS's exemption is
modified as follows:
1. Concentrations of SNM in individual waste containers and/or
during processing shall not exceed the following values:
[[Page 55073]]
------------------------------------------------------------------------
Measurement
Operational uncertainty
SNM Isotope limit (gram SNM/ (gram SNM/gram
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] TN26OC09.000
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:
----------------------------------------------------------------------------------------------------------------
SNM Isotope Carbon Fluorine Bismuth
----------------------------------------------------------------------------------------------------------------
U-233............................... 28 wt%.................. 34 wt%................. 34 wt%.
U-235(10)........................... 25 wt%.................. 35 wt%................. 31 wt%.
U-235(100).......................... 41 wt%.................. 42 wt%................. 33 wt%.
Pu-239.............................. 43 wt%.................. 43 wt%................. 34 wt%.
Pu-241.............................. 37 wt%.................. 39 wt%................. 32 wt%.
----------------------------------------------------------------------------------------------------------------
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 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.
b. 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.
c. 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.
d. 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
[[Page 55074]]
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. 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.
9. WCS shall obtain NRC approval prior to changing any activities
associated with the above Conditions.
III.
Based on the staff's evaluation, the Commission 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 Commission hereby
grants this exemption subject to the above conditions. The exemption
will become effective after the State of Texas has incorporated the
above conditions into WCS's RML.
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. This
finding was noticed in the Federal Register on October 15, 2009 (74 FR
52981-52985).
Dated at Rockville, Maryland this 20th day of October 2009.
