40 CFR Part 268
[EPA-HQ-RCRA-2007-0936; FRL-8565-9]
Land Disposal Restrictions: Site-Specific Treatment Variance for
P- and U-Listed Hazardous Mixed Wastes Treated by Vacuum Thermal
Desorption at the Energy Solutions' Facility in Clive, UT
AGENCY: Environmental Protection Agency.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA or the Agency) is
promulgating a final rule granting a site-specific treatment variance
to EnergySolutions LLC (EnergySolutions) in Clive, Utah for the
treatment of certain P- and U-listed hazardous waste containing
radioactive contamination (``mixed waste'') using vacuum thermal
desorption (VTD). This variance is an alternative treatment standard to
treatment by combustion (CMBST) required for these wastes under EPA's
rules in implementing the land disposal restriction (LDR) provisions of
the Resource Conservation and Recovery Act (RCRA). The Agency has
determined that combustion of the solid treatment residue generated
from the VTD unit is technically inappropriate due to the effective
performance of the VTD unit. Thus, once the P- and U-listed mixed waste
are treated using the VTD unit, the solid treatment residue can be land
disposed without further treatment. This variance is conditioned upon
EnergySolutions complying with a Waste Family Demonstration Testing
(WFDT) plan specifically addressing the treatment of these P- and U-
listed wastes, which is to be implemented through a RCRA Part B permit
modification for the VTD unit.
DATES: This final rule will be effective June 13, 2008.

I. Summary of This Action
EPA is promulgating, as proposed, a site-specific treatment
variance to EnergySolutions in Clive, Utah for the treatment of certain
P- and U-listed mixed waste using an alternative treatment standard of
VTD.\1\ The current treatment standard for these wastes is combustion
(CMBST). See 40 CFR 268.40 and 268.42.
---------------------------------------------------------------------------
\1\ Mixed waste is defined as radioactive waste that contains
hazardous waste that either: (1) Is listed as a hazardous waste in
Subpart D of 40 CFR Part 261; or (2) causes the waste to exhibit any
of the hazardous waste characteristics identified in Subpart C of 40
CFR Part 261. Mixed waste is regulated under multiple authorities:
RCRA (for the non-radioactive component), as implemented by EPA or
authorized States; and the Atomic Energy Act (AEA) (for the source,
special nuclear, or by-product material component), as implemented
by the Nuclear Regulatory Commission (NRC), NRC agreement States
(for commercially-generated mixed wastes), or the Department of
Energy (DOE) (for defense-related mixed waste generated by DOE
activities). The variance is limited to the RCRA requirements for
treatment of the hazardous waste portion of the mixed waste and does
not affect the regulations under AEA authority.
---------------------------------------------------------------------------
EnergySolutions' VTD unit currently operates pursuant to a Part B
RCRA permit issued by the State of Utah which (among other things)
authorizes the treatment of mixed waste containing both semi-volatile
organic compounds (SVOC) and volatile organic compounds (VOC). In 2006,
EnergySolutions submitted a petition to EPA for a site-specific
treatment variance from the LDR treatment standard of CMBST for various
P- and U-listed mixed waste. The petitioner is seeking an alternative
treatment standard of VTD.
[[Page 27762]]
EnergySolutions provided data and information indicating that the VTD
unit is capable of achieving at least 99.99% removal of analyzable SVOC
\2\ and VOC \3\ constituents in the solid treatment residue generated
from the VTD unit; analysis of the solid treatment residue shows that
the LDR concentration-based treatment standards for these chemical
constituents are consistently achieved. (Concentration-based treatment
standards for specific chemical constituents are found in 40 CFR
268.48.) The petitioner also supplied performance data demonstrating
that the VTD unit effectively removes chemical compounds (in the SVOC
and VOC families) from the mixed waste having similar chemical and
physical properties (i.e., boiling points and vapor pressures) to the
regulated hazardous constituents in the P- and U-listings that are the
subject of this site-specific treatment variance. These P- and U-listed
wastes are not analyzable, hence the treatment standard of CMBST.
EnergySolutions contends that additional treatment of the solid
treatment residue from the VTD unit, using the treatment method of
CMBST, would be technically inappropriate in that substantial
treatment, as measured with the use of similar chemical compounds, has
already been achieved using the VTD unit.
---------------------------------------------------------------------------
\2\ The SVOC waste family is defined as those chemical compounds
that are detected using SW-846 Method 8270.
\3\ The VOC waste family is defined as those chemical compounds
that are detected using SW-846 Method 8260.
---------------------------------------------------------------------------
The Agency has reviewed the information and data presented by the
petitioner and has determined that additional treatment of the solid
treatment residue (i.e., complying with the existing CMBST treatment
standard) is technically inappropriate given the documented performance
of the VTD unit. The Agency is therefore taking final action to grant a
site-specific treatment variance to EnergySolutions for an alternative
LDR treatment standard of VTD for certain P- and U-listed mixed wastes
that have undergone treatment using the VTD process. Once treated, the
solid treatment residue can be land disposed: in this case, in
EnergySolutions' on-site hazardous mixed waste landfill. As a condition
of this treatment variance, EnergySolutions must comply with a WFDT
plan that establishes conditions on the treatment process that will
assure optimized treatment of the mixed waste, which is implemented
through a RCRA Part B permit modification of the VTD unit.
II. Background
Under sections 3004(d) through (g) of RCRA, the land disposal of
hazardous wastes is normally prohibited unless such wastes are able to
meet the treatment standards established by EPA. Section 3004(m) of
RCRA requires EPA to set levels or methods of treatment that
substantially diminish the hazardous waste's toxicity or substantially
reduce the likelihood of hazardous constituents migrating from the
waste so that short-term and long-term threats to human health and the
environment posed by the waste's land disposal are minimized. EPA
interprets this language to authorize treatment standards based on the
performance of best demonstrated available technology (BDAT). This
interpretation was upheld by the D.C. Circuit in Hazardous Waste
Treatment Council v. EPA, 886 F.2d 355 (D.C. Cir. 1989).
However, facilities can apply for a site-specific treatment
variance in cases when a hazardous waste that is generated cannot be
treated to the specified levels or when it is technically inappropriate
for the waste to undergo such treatment (See 51 FR at 40605-40606
(November 7, 1986)). In such cases, the generator or treatment facility
may apply for a variance from a treatment standard. The requirements
for a treatment variance are found at 40 CFR 268.44.\4\
---------------------------------------------------------------------------
\4\ In the case where the rules specify that a method of
treatment must be used to treat a particular constituent or
constituent(s), EPA also allows facilities to demonstrate that an
alternative treatment method can achieve a measure of performance
equivalent to that achievable by the EPA-specified treatment method
(40 CFR 268.42(b)). This demonstration of equivalency, known as a
Determination of Equivalent Treatment (DET), is typically both
waste-specific and site-specific. EPA notes that the petition
submitted by EnergySolutions appears to meet the criteria of 40 CFR
268.42(b) in that the VTD unit removes SVOC and VOC constituents
with the same efficiency as hazardous waste combustion units.
However, while the Agency could choose to evaluate the petition
under the criteria developed for a DET, we are processing
EnergySolutions petition under the criteria found in 40 CFR 268.44,
as requested in EnergySolutions's petition to EPA. Today's decision
is thus based on the rationale provided by EnergySolutions'
treatment variance petition, i.e., that it is inappropriate to
require the waste to be treated by the method specified as the
treatment standard (i.e., CMBST), even though such treatment is
technically possible (see 40 CFR 268.44(h)(2)).
---------------------------------------------------------------------------
An applicant for a site-specific treatment variance may demonstrate
that it is inappropriate to require a waste to be treated by the method
specified as the treatment standard, even though such treatment is
technically possible (40 CFR 268.44(h)(2)). This is the criterion
pertinent to today's action in that EnergySolutions claims it is
technically inappropriate to further treat the waste (i.e., solid
treatment residue) that has already been treated to remove over 99.99%
of the hazardous organic constituents contained in the waste.
III. Development of This Variance
A. EnergySolutions' Petition
On April 28, 2006, EnergySolutions petitioned EPA for a site-
specific treatment variance from the treatment standard of combustion
(CMBST) for certain P- and U-listed mixed wastes.\5\ EnergySolutions
requested an alternative treatment standard of VTD \6\ which would
allow the land disposal of the solid treatment residue from the VTD
unit without having to combust the treatment residue (as required by
the CMBST treatment standard). The petitioner contends that additional
treatment is inappropriate and would result in little if any additional
reduction of the waste's toxicity.
---------------------------------------------------------------------------
\5\ Under 40 CFR 268.42, ``CMBST'' is defined as ``[h]igh
temperature organic destruction technologies, such as combustion in
incinerators, boilers, or industrial furnaces operated in accordance
with the applicable requirements of 40 CFR Part 264, Subpart O, or
40 CFR Part 265, Subpart O, or 40 CFR Part 266, Subpart H, and in
other units operated in accordance with applicable technical
operating requirements; and certain non-combustive technologies,
such as the Catalytic Extraction Process.'' EnergySolutions' VTD
does not meet this definition.
\6\ For certain P- and U-listed wastes, EPA was not able to
identify an analytical method by which treatment effectiveness could
be determined in the regulated constituent. As a result, EPA
promulgated CMBST as the treatment standard for these P- and U-
listed wastes. CMBST was selected as the method of treatment because
it is relatively indiscriminate in the destruction of organics due
to the high temperatures, efficient mixing, and consistent residence
times present in a well-designed and well-operated facility (see 55
FR 22611, June 1, 1990.)
---------------------------------------------------------------------------
EnergySolutions provided data and information indicating that
treatment using their VTD unit achieves substantial reductions in the
concentrations of organic constituents (greater than 99.99%) in the
solid treatment residue. Data included SVOC and VOC concentrations in
the untreated waste, organic liquid condensate and solid treatment
residue from demonstration tests conducted in August and September of
2004 and October of 2006. The petitioner also supplied performance data
indicating that the VTD unit can remove 99.99% of organic constituents
with chemical and physical properties (i.e., boiling points and vapor
pressures) similar to the organic constituents in the P- and U-listed
hazardous waste identified in their petition.\7\ The petitioner also
[[Page 27763]]
provided a description of the analytical and methodological protocol
established by the State of Utah that describes how the VTD unit will
be optimized to assure continued optimized removal of hazardous organic
constituents from P- and U-listed mixed waste.
---------------------------------------------------------------------------
\7\ The specific P- and U-listed hazardous wastes associated
with the untreated mixed waste had been conservatively determined by
the facility, in consultation with the State of Utah, using the
``derived-from rule'' described in 40 CFR 261.3(c)(2)(i). A listing
of the specific waste codes and chemical applicable to this rule can
be found in the docket supporting this rule.
---------------------------------------------------------------------------
On March 6, 2008 (73 FR 12043), the Agency issued a direct final
rule and a parallel proposal (73 FR 12043) granting a site-specific
treatment variance to EnergySolutions for the treatment of certain P-
and U-listed mixed waste using the VTD unit. The treatment variance
established an alternative treatment standard to treatment by
combustion (CMBST) required for these wastes under EPA's rules
implementing the LDR provisions of RCRA. The Agency made the
determination that combustion of the solid treatment residue generated
from the VTD unit was technically inappropriate due to the effective
performance of the VTD unit. The treatment variance was conditioned
upon EnergySolutions complying with a WFDT plan specifically addressing
the treatment of these P- and U-listed wastes, which is to be
implemented through a RCRA Part B permit modification for the VTD unit.
We stated in the preamble to the direct final rule and parallel
proposal that if we received adverse comment we would withdraw the
direct final rule and proceed with a subsequent final rule. We received
adverse comment on the direct final rule and therefore withdrew the
direct final rule as of May 2, 2008.
B. Comments Received on Variance and Agency's Response
The Agency received four comments on the direct final rule. Two of
the comments were identical, and urged the Nuclear Regulatory
Commission (NRC) to deny EnergySolutions' request to import nuclear
waste into the United States for disposal. We have concluded that these
comments are not germane to the treatment variance and addressed an
issue outside the scope of this rulemaking. The third comment supported
granting the site-specific treatment variance to EnergySolutions. The
final comment raised concerns about radioactive waste being treated in
Utah and EPA's determination that the only regulated entity that would
be affected by the rule would be EnergySolutions (see 73 FR at 12044).
The commenter argued that EnergySolutions was not the only affected
party and stated that the commenter, the State of Utah, and the United
States would be affected by granting this treatment variance. The
commenter, however, did not state why or how these entities would be
affected. While the commenter's assertion that citizens, the States,
and the federal government could be affected by this action may be
correct in the broadest sense, we believe that it has no relation to
the narrow question at issue here of whether the criteria for a
treatment variance are satisfied. However, EPA believes firmly that no
entities will be adversely affected by granting the treatment variance.
First, EnergySolutions is a permitted hazardous waste treatment,
storage and disposal facility and is subject to regulations and permit
conditions which assure protection of human health and the environment.
Second, the unchallenged record indicates that EnergySolutions' method
of treatment fully satisfies the criterion for a treatment variance;
that is, the method of treatment is one that minimizes threats to human
health and the environment posed by land disposal of the wastes being
treated.\8\
---------------------------------------------------------------------------
\8\ It should be noted that even if the Agency were to deny
EnergySolutions' petition, it would not prevent them from treating
these wastes, although the solid treatment residue generated from
the VTD unit would need to be further treated by CMBST. However, the
data and information provided by EnergySolutions demonstrates that
such further treatment is inappropriate.
---------------------------------------------------------------------------
After review of the comments, the Agency has determined that the
site specific treatment variance to EnergySolutions should be
promulgated.
C. What Type and How Much Mixed Waste Are Subject to This Variance?
The wastes subject to this variance are mixed waste consisting of
discarded commercial chemical products (P- and U-listed hazardous
wastes) that are required to meet the technology performance standard
of CMBST.\9\ It also includes secondary waste (e.g., carbon filter
media) generated by the EnergySolutions' VTD unit during the processing
of the mixed waste.
---------------------------------------------------------------------------
\9\ A list of these chemicals, with associated boiling point
data, is included as part of the docket supporting this rulemaking.
---------------------------------------------------------------------------
The Department of Energy (DOE) has identified approximately 50
cubic meters (m3) of mixed waste (tank sludges and
decontamination residues) in legacy storage in Oak Ridge, Tennessee.
EnergySolutions has also identified an additional 900 m3 of
hardened tank sludge at a commercial facility. Another potential source
of hazardous waste to be treated by EnergySolutions' VTD unit is from a
commercial chemical manufacturer. The waste can be characterized as
tank sludge, much of which is in a hardened/compressed form, identified
as U053 (crotonaldehyde) and U122 (formaldehyde) mixed waste.\10\
---------------------------------------------------------------------------
\10\ Waste codes are assigned by the generator based upon
process knowledge of raw feed materials and by-products within the
chemical manufacturing process.
---------------------------------------------------------------------------
D. Description of the VTD Process
EnergySolutions' VTD unit holds a permit from the State of Utah as
a RCRA Subpart X miscellaneous treatment unit. This permit allows the
facility to treat mixed waste that contains SVOC and VOC waste
families. The VTD unit has been in operation since March 2005, and has
processed more than 304,000 kilograms (kg) of mixed waste.
EnergySolutions' VTD process design achieves a removal efficiency of
99.99% for SVOC and VOC waste families in the VTD solid treatment
residue and meets all applicable LDR concentration-based treatment
standards. Treatment residue from the unit is land disposed at
EnergySolutions' on-site permitted mixed waste landfill after all other
regulatory requirements are met.
The VTD unit consists of four subsystems: (1) A thermal separation
system (dryer); (2) a processed material discharge system; (3) an off-
gas treatment train; and (4) a condensate tank system.\11\ The
treatment system operates by indirectly heating the raw waste fed into
the unit, vaporizing the volatile and semi-volatile organic
constituents and capturing these constituents as a condensate. The
process has one input stream (the raw waste) and three output streams.
The three output streams are: (1) The solid treatment residue; (2) the
concentrated liquid condensate; and (3) an off-gas, which is released
to the atmosphere after passing through a series of filters and
condensers. It should be noted that the liquid condensate and the off-
gas are not subject to this rulemaking. The condensate is still subject
to the CMBST treatment standard before it can be land disposed, and is
sent off-site for incineration. The off-gas emission is regulated under
a state-issued Part B Permit (its emission limits established using a
risk assessment under 40 CFR 270.32(b)(2) (the so-called omnibus
provision) and by an Air Approval Order issued by the Utah Department
of Environmental Quality).
---------------------------------------------------------------------------
\11\ A process diagram of the EnergySolutions' VTD unit can be
found in the docket supporting this rulemaking. Schematic drawings
of the equipment are also provided.
---------------------------------------------------------------------------
The thermal separation unit or dryer is a completely enclosed
cylindrical
[[Page 27764]]
tank with a processing capacity of approximately 29 cubic feet
(ft3) of feed material per process cycle. Several process
cycles can be run per day. It is indirectly heated by a propane-fired
furnace and is permitted to reach process temperatures up to 650
[deg]C. The feed material is introduced into the dryer through a
hopper. The system is maintained below atmospheric pressure by a vacuum
pump. Nitrogen is introduced to displace oxygen to a level no greater
than 7%, which is below the oxygen ignition point for the volatile and
semi-volatile contaminants. The nitrogen purge gas carries the
volatilized contaminants from the dryer to the off-gas treatment train.
Treatment time and temperature in the dryer are established for each
process cycle following the characterization of the raw waste.
The processed material discharge system is fully enclosed and
consists of a hopper with a cooling jacket, a conveyor system, and a
collection container. The system includes water spray nozzles to aid in
cooling the processed material and to provide dust control. The dry
processed material is collected in the discharge system after the
process cycle is completed. An auger conveys the discharged solid to a
metal receiving box. Post-treatment analytical samples are collected
from the box or directly from the processed material discharge system
and tested for all analyzable regulated constituents originally
identified in the waste feed. Once successful verification results are
received, the process material is land disposed at EnergySolutions' on-
site mixed waste landfill.
Off-gas is generated within the dryer and is purged with a nitrogen
carrier gas. The off-gas treatment train, also called the air pollution
control (APC) system, consists of condensers in series, a vacuum pump,
and a filtration adsorption system with a pre-filter, HEPA filter, and
carbon adsorption beds. The nitrogen provides a relatively inert
atmosphere (oxygen content less than 7%), which prevents combustion of
the volatile or semi-volatile constituents. The gas stream then passes
through the filtration system to remove the remaining SVOC and VOC.
Hot gas from the dryer is fed to the condensers and the condensers
cool the gas stream and the majority of the volatile and semi-volatile
compounds are brought to a liquid phase. The condensate tank system
consists of traps, for temporary storage, from which the liquid
condensate can either be transferred to permanent tanks or to portable
totes. Traps located in the liquid discharge line from the condensers
collect the condensate. It is then sent off-site for incineration at a
RCRA permitted facility.
The liquid condensate is more amenable to combustion than the
untreated waste.\12\ Incineration of the liquid condensate optimizes
the destruction of toxic organics and yields a smaller volume of post-
incineration waste. The liquid condensate contains approximately 5% of
the total amount of radionucliides in the untreated waste and presents
a significantly lower potential for radioactive materials to be emitted
to the atmosphere through the combustion process.
---------------------------------------------------------------------------
\12\ Analytical data on the organic condensate and solid process
residuals from the VTD demonstration tests completed in August and
September of 2004 and October of 2006 can be found in the docket
supporting this rulemaking.
---------------------------------------------------------------------------
The off-gas emission is vented to the atmosphere through a stack
that discharges approximately 35 feet above ground level. The gas
emission leaves the APC system and its exit velocity is boosted with
outside air through a blower in order to provide good dispersion of any
remaining emissions. The APC system also is designed to allow the
carrier gas to be recycled back to the dryer. System data are displayed
as an electronic process flow diagram that is continuously monitored by
trained technicians. Dryer temperature, dryer pressure, oxygen level
and off-gas exit temperature are included in the parameters that are
measured.\13\
---------------------------------------------------------------------------
\13\ More detailed information on the EnergySolutions' VTD
technology process can be found in the docket for this rulemaking.
---------------------------------------------------------------------------
The facility currently ships separately the solid treatment
residue, containing the majority of the radionucliides (over 95%) and
negligible concentration of organics to its on-site hazardous mixed
waste landfill, and the liquid condensate, containing the majority of
the organic constituents, to an incinerator to meet the CMBST
requirement. The incineration takes place in a unit permitted for both
the radioactive component and for RCRA hazardous wastes.\14\
---------------------------------------------------------------------------
\14\ There are only two permitted mixed waste incinerators in
the U.S. These facilities, due to the operational design of their
units, have greater available capacity to accept liquid condensate
waste and have a backlog of solid mixed wastes.
---------------------------------------------------------------------------
IV. EPA's Reasons for Granting This Variance
EPA has determined that given the similarities in chemical and
physical properties and separation characteristics between the SVOC and
VOC mixed waste and the P- and U-listed mixed wastes, that processing
the P- and U-listed mixed waste through the VTD unit will achieve the
same level of treatment performance achieved for the SVOC and VOC mixed
waste (i.e., 99.99% removal in the solid treatment residue).
Furthermore, EPA has concluded that subsequent combustion of the solid
treatment residue from the VTD unit will not substantially reduce its
toxicity so that subsequent treatment by the required treatment
standard of CMBST is unnecessary and will achieve no additional
benefit. This is because the solid treatment residue has negligible
concentrations of the residual organics. Put another way, EPA has
determined that additional treatment with CMBST, as required by the
treatment standard of CMBST, is technically inappropriate due to the
effectiveness of the VTD treatment for the removal of organic
constituents. Therefore, EPA is promulgating this final action to grant
a site-specific treatment variance to EnergySolutions for an
alternative treatment standard of VTD for the land disposal of the
solid treatment residue from the treatment of certain P- and U-listed
mixed waste.
Not only would further treatment of the residue be technically
inappropriate, but it could have environmentally detrimental effects.
Under their state-issued Part B permit, EnergySolutions is required to
operate the VTD unit so that most (generally over 95%) of the
radioactive component remains in the solid treatment residue.\15\
Combustion of that treatment residue could release some of the
radioactive component to the atmosphere through the combustion process.
To limit this potential, the Agency believes that processing the P- and
U-listed hazardous wastes through the VTD unit followed by disposal of
the solid treatment residue in the on-site mixed waste landfill is
environmentally preferable.
---------------------------------------------------------------------------
\15\ Data relating to radiochemical properties of the condensate
generated through the process is included in the docket supporting
this rulemaking.
---------------------------------------------------------------------------
V. Conditions of the Variance
Although EPA believes the applicant has made a technically sound
presentation, and believes further that the VTD process should continue
to result in highly effective treatment, EPA (and the applicant, and
the State of Utah (the authorized permit-issuer)) believes that
conditions can and should be imposed on the treatment process to assure
its continued effective operation. Therefore, as a condition of its
RCRA permit, EnergySolutions is required to submit to the State of Utah
all the appropriate data and documentation, as part of a RCRA Part B
permit modification, addressing the treatment of these P- and U-listed
mixed wastes using VTD. Most significantly for
[[Page 27765]]
purposes of the treatment variance, this submission is to include a new
WFDT plan for P- and U-listed mixed wastes developed by the facility
and approved by the State of Utah. This plan identifies the surrogate
compounds that reflect treatment of the most difficult to treat CMBST-
coded organic compounds (e.g., those with the highest vapor pressures
and boiling points).\16\ Surrogates will have to be selected to measure
the level of treatment of the organic compounds that do not have
analytical methods of detection or quantification. The RCRA permit,
when modified, will require compliance with this WFDT plan for each
batch of P- and U-listed mixed waste that requires CMBST.\17\ EPA's
site-specific treatment variance is conditioned on EnergySolutions'
adhering to the WFDT plan specifically addressing the treatment of
these P- and U-listed wastes.
---------------------------------------------------------------------------
\16\ The objectives of the WFDT are: (1) Determine if the P- and
U-listed hazardous wastes that have CMBST as the LDR treatment
standard are amenable to VTD processing and that the processed
material meets the LDR standards for all analyzable P and U
hazardous organic constituents; (2) identify and justify
representative surrogate compounds for the demonstration for those P
and U hazardous organic constituents that do not have an analytical
method of detection; (3) determine the optimal operational and
system parameters for the new waste family that will ensure at least
99.99 percent removal efficiency is attained for such hazardous
wastes; (4) account for toxic waste constituents through material
balances; (5) verify compliance of the VTD unit with all applicable
conditions of the EnergySolutions' state-issued Part B Permit; and
(6) determine concentration levels for the hazardous organic
constituents in treatment residuals to determine that they are below
analytical reporting levels, including surrogate compounds chosen
for non-analyzable or difficult to treat organics.
\17\ If the conditions outlined in the WFDT plan are not met for
each batch of P- and U-listed mixed waste, EnergySolutions must re-
treat the batch of waste to meet the conditions established in the
plan or send the waste off-site for CMBST.
---------------------------------------------------------------------------
A WFDT plan is required in the state-issued Part B permit for every
new waste type to be treated in the EnergySolutions' VTD unit. Because
many of the organic chemicals in P- and U-listed hazardous waste do not
have analytical methods for detection or quantification, the WFDT plan,
as required by the permit, will need to identify individual surrogate
compounds that reflect treatment of the non-analyzable organic
compounds in the waste family. The volatility of each target
contaminant is the most important factor in thermal desorption
separation.\18\ Most of these chemicals (99 of 139) have boiling points
less than 200 [deg]C, 28 have boiling points between 200 [deg]C and 300
[deg]C, seven have boiling points between 300 [deg]C and 400 [deg]C,
four have boiling points between 400 [deg]C and 500 [deg]C, and only
one of the compounds has a boiling point greater than 500 [deg]C; at
534 [deg]C. The VTD system is permitted to operate at temperatures up
to 650 [deg]C. Based on the volatility of the organic constituents in
the boiling point table and the operational temperature of the VTD
unit, processing these P- and U-listed hazardous waste through the VTD
system can be expected to remove the organic constituents (especially
those organics requiring CMBST) from the solid feed material and
concentrate them within the liquid condensate, including the surrogates
chosen to represent the non-analyzable P- and U-listed organic
constituents.
---------------------------------------------------------------------------
\18\ The CMBST Code Boiling Point Table is included in the
docket supporting this rulemaking. It provides boiling point data
for those non-analyzable hazardous organics that require CMBST as
the LDR treatment standard.
---------------------------------------------------------------------------
Surrogates are also used to measure the performance of the VTD
unit. Rather than test each specific organic constituent associated
with each waste family, the facility chooses surrogate compounds to
represent the most difficult to treat organic chemicals in the entire
waste family matrix (i.e., highest boiling points and pressure vapors).
The WFDT plan must identify these surrogate compounds to be spiked into
the waste as indicators for the entire waste family performance in the
VTD unit.
VI. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
This action is not a ``significant regulatory action'' under the
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is
therefore not subject to review under the Executive Order.
B. Paperwork Reduction Act
This action does not impose any new information collection burden.
This action grants a site-specific treatment variance to
EnergySolutions for the treatment of certain P- and U-listed mixed
wastes using their VTD unit instead of the treatment standard required
under RCRA's LDR program, CMBST. However, the Office of Management and
Budget (OMB) has previously approved the information collection
requirements contained in the existing regulations at 40 CFR 268.42 and
268.44 under the provisions of the Paperwork Reduction Act, 44 U.S.C.
3501 et seq. and has assigned OMB control number 2050-0085. The OMB
control numbers for EPA's regulations in 40 CFR are listed in 40 CFR
part 9.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an agency
to prepare a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements under the Administrative
Procedure Act or any other statute unless the agency certifies that the
rule will not have a significant economic impact on a substantial
number of small entities. Small entities include small businesses,
small organizations, and small governmental jurisdictions.
This site-specific treatment variance does not create any new
requirements. Rather, it establishes an alternative treatment standard
for specific waste codes and applies to only one facility. Therefore,
we hereby certify that this rule will not add any new regulatory
requirements to small entities. This rule, therefore, does not require
a regulatory flexibility analysis.
D. Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for Federal agencies to assess the
effects of their regulatory actions on State, local, and tribal
governments and the private sector. Under section 202 of UMRA, EPA
generally must prepare a written statement, including a cost-benefit
analysis, for proposed and final rules with ``Federal mandates'' that
may result in expenditures to State, local, and tribal governments, in
the aggregate, or to the private sector, of $100 million or more in any
one year. Before promulgating an EPA rule for which a written statement
is needed, sections 205 of UMRA generally requires EPA to identify and
consider a reasonable number of regulatory alternatives and adopt the
least costly, most cost-effective or least burdensome alternative that
achieves the objectives of the rule. The provisions of section 205 do
not apply when they are inconsistent with applicable law. Moreover,
section 205 allows EPA to adopt an alternative other than the least
costly, most cost-effective or least burdensome alternative if the
Administrator publishes with the final rule an explanation why that
alternative was not adopted. Before EPA establishes any regulatory
requirements that may significantly or uniquely affect small
governments, including tribal governments, it must have developed under
section 203 of UMRA a small government agency plan. The plan must
provide for notifying potentially affected small governments, enabling
officials of affected small governments
[[Page 27766]]
to have meaningful and timely input in the development of EPA
regulatory proposals with significant Federal intergovernmental
mandates, and informing, educating, and advising small governments on
compliance with the regulatory requirements.
Today's rule contains no Federal mandates (under the regulatory
provisions of Title II of UMRA) for State, local, or tribal governments
or the private sector. The rule imposes no enforceable duty on any
State, local or tribal governments or the private sector.
EnergySolutions will obtain from the State of Utah a RCRA permit
modification for their VTD unit to treat these P- and U-listed wastes.
This action, however, does not impose any new duties on the state's
hazardous waste program. EPA has determined, therefore, that this rule
contains no regulatory requirements that might significantly or
uniquely affect small governments.
E. Executive Order 13132: Federalism
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
Policies that have ``federalism implications'' are defined in the
Executive Order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.''
This final rule does not have federalism implications. It will not
have substantial direct effects on the States, on the relationship
between the national government and the States, or on the distribution
of power and responsibilities among the various levels of government,
as specified in Executive Order 13132. This action finalizes a site-
specific treatment variance applicable to one facility. Thus, Executive
Order 13132 does not apply to this rule.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
Executive Order 13175, entitled ``Consultation and Coordination
with Indian Tribal Governments'' (59 FR 22951, November 9, 2000),
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by tribal officials in the development of regulatory
policies that have tribal implications.'' This final rule does not have
tribal implications, as specified in Executive Order 13175. This action
is a site-specific treatment variance that applies to only one
facility, which is not a tribal facility or located on tribal lands.
Thus, Executive Order 13175 does not apply to this rule.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997)
as applying only to those regulatory actions that are based on health
or safety risks, such that the analysis required under section 5-501 of
the Executive Order has the potential to influence the regulation. This
action is not subject to Executive Order 13045 because it does not
establish an environmental standard intended to mitigate health or
safety risks.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This rule is not subject to Executive Order 13211, ``Actions
Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use'' (66 FR 28355 (May 22, 2001)) because it is not a
significant regulatory action under Executive Order 12866.
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, section 12(d) (15 U.S.C.
272 note) directs EPA to use voluntary consensus standards in its
regulatory activities unless to do so would be inconsistent with
applicable law or otherwise impractical. Voluntary consensus standards
are technical standards (e.g., materials specifications, test methods,
sampling procedures, and business practices) that are developed or
adopted by voluntary consensus standards bodies. The NTTAA directs EPA
to provide Congress, through OMB, explanations when the Agency decides
not to use available and applicable voluntary consensus standards.
The final rule does not involve technical standards. Therefore, EPA
did not consider the use of any voluntary consensus standards.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order 12898 (59 FR 7629 (February 16, 1994)) establishes
federal executive policy on environmental justice. Its main provision
directs federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
EPA has determined that this final rule will not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations because it does not
affect the level of protection provided to human health or the
environment. The site-specific treatment variance being finalized
applies to certain P- and U-listed mixed waste that is treated in an
existing, permitted RCRA facility, ensuring protection to human health
and the environment. Therefore, the rule will not result in any
disproportionately negative impacts on minority or low-income
communities relative to affluent or non-minority communities.
K. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this rule and other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A Major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule as defined by U.S.C.
804(2). This rule will be effective June 13, 2008.

\1\ A facility may certify compliance with these treatment standards according to provisions in 40 CFR 268.7.
\14\ This site-specific treatment variance applies only to solid treatment residue resulting from the vacuum thermal desorption (VTD) of P- and U-listed
hazardous waste containing radioactive contamination (``mixed waste'') at the EnergySolutions' LLC facility in Clive, Utah that otherwise requires
CMBST as the LDR treatment standard. Once the P- and U-listed mixed waste are treated using VTD, the solid treatment residue can be land disposed at
EnergySolutions' onsite RCRA permitted mixed waste landfill without further treatment. This treatment variance is conditioned on EnergySolutions
complying with a Waste Family Demonstration Testing Plan specifically addressing the treatment of these P- and U-listed wastes, with this plan being
implemented through a RCRA Part B permit modification for the VTD unit.
Note: NA means Not Applicable.
