A. What are the terms of this exclusion?
B. When is the delisting effective?
C. How does this action affect the states?
IV. Statutory and Executive Order Reviews
I. Overview Information
Based on a petition submitted to the EPA, Energy requested
technical amendments to an existing exclusion from the list of
federally listed wastes set forth in 40 Code of Federal Regulations
(CFR) 261.33 previously issued to the United States Department of
Energy (Energy) for the Hanford Federal Facility, or Hanford Site in
Richland, Washington (Current delisting). See 40 CFR part 261, appendix
IX, Table 2. This existing exclusion applies to treated effluent
generated by Hanford's 200 Area Effluent Treatment Facility (ETF). The
requested amendments relate to the planned startup of the Hanford Waste
Treatment and Immobilization Plant (WTP). Details of Energy's requested
technical amendments are more fully described in EPA's proposed
regulatory amendments to the existing delisting at 86 (FR) 30237, June
7, 2021. After consideration of comments received on the EPA's proposed
regulatory amendments, the EPA is finalizing these amendments as
proposed. The EPA is also making one grammatical clarification
identified after the proposal cited above.
II. EPA's Evaluation of Public Comments
The EPA received one anonymous set of comments on the proposed
regulatory amendments. These comments, and the EPA's evaluation of
them, are described below.
This commenter raises several issues. One common theme is that
there are data gaps or other uncertainties regarding the ability of the
Effluent Treatment Facility to manage future wastes from the WTP. The
following sections address each of the comments that have a clear nexus
to the proposed modification of the existing 200-Area ETF delisting.
Uncertainty Regarding the Future Capability To Treat ``the Future
Unknowns''
The commenter stated ``It appears that the current petition
revision is solely to address acetonitrile, but that there are other
unknowns and chemicals of concern to be submitted at a later date for
future delisting petitions. There is no guarantee that there will be a
future capability to treat the future unknowns, leaving a considerable
risk of what to do with non-compliant effluent from the WTP.''
In promulgating significant revisions to the 200-ETF delisting in
2005 (70 FR 44498, July 30, 2012), Ecology and EPA explicitly intended
to broadly expand the waste streams that the ETF could process within
the scope of the treated effluent delisting. More specifically, the
final delisting rule stated ``The effect of these changes is to allow
the 200 Area ETF to fulfill an expanded role in supporting Hanford
Facility cleanup actions beyond those activities considered in the 1995
delisting rulemaking. In particular, these changes will allow the 200
Area ETF to treat mixed wastewaters from a number of additional sources
beyond 242-A Evaporator process condensate (PC) upon which the original
delisting was based.'' (See 70 FR 44497, July 30, 2012).
Consistent with this objective, the 2005 delisting modifications
established a detailed mechanism based on the concept of a treatability
envelope, which defines the ability of the ETF system overall to treat
a wide range of waste constituents. This mechanism is based on an
engineering model of the various unit operations within the ETF
treatment train. Additionally, constituent-specific data for a wide
range of constituents were used on a waste-stream specific basis to
evaluate the treatability of that waste stream as part of the waste
acceptance process for
[[Page 50648]]
the ETF. A target goal with this approach was to establish a delisting
framework that could consider future waste streams for which
characterization data was not available at the time, but that could be
managed in the future. More importantly, as Ecology and EPA noted in
the 2005 delisting rulemaking ``[s]ince Energy could not reasonably
provide detailed characterization of wastes streams that have yet to be
generated, EPA proposed a waste acceptance framework based on an
engineering evaluation of waste streams. This model provides a degree
of confidence that treatment in the 200 Area ETF will meet delisting
exclusion limits to the same degree of confidence as if detailed waste
stream characterization were available, while avoiding the need to
frequently revise the delisting rule itself.'' (See 70 FR 44499, July
30, 2012).
Liquid effluents from the Waste Treatment Plant are one example of
wastes that, in 2005, were expected to be generated in the future, but
were not sufficiently characterized in order to be evaluated at that
time. Since the 2005 modifications, the Department of Energy has made
progress in both the design and operation of the planned WTP, including
a detailed characterization of the liquid effluents from the WTP
through engineering design and modelling. (See the engineering report
and associated supporting calculation documents provided in the docket
for the current delisting modifications). From this work, Energy
identified a number of constituents in WTP liquid effluent that would
need to be considered in the context of the ETF delisting. Energy has
provided a request to the EPA (21-ECD-001774 dated June 29, 2021,
available in the Hanford administrative records at <a href="http://www.hanford.gov">www.hanford.gov</a>) to
consider five of these additional constituents through a modification
of Tables C-1 and C-2 pursuant to Condition (1)(b) of the existing
delisting. This request is consistent with the mechanism already in
place under the existing delisting. Because the June 29, 2021 request
is outside the scope of this modification to the delisting rule itself,
the request to add five additional constituents identified in the June
29, 2021 request are not further considered in this comment response,
but will be addressed by EPA's expected future response to the June 29,
2021 request.
As documented in its request for a modification of the 200 Area ETF
delisting, Energy identified that acetonitrile exceeded the existing
treatability envelope for that constituent. Based on our analysis of
information provided by Energy for the current proposed modification,
and the overall structure and content of the 2005 modifications to the
delisting, EPA and Ecology have determined that with the current
proposed modifications, the 200-Area ETF is fully capable of accepting
reasonably expected liquid effluents from the WTP, and that there is
little if any regulatory, environmental, or project risk associated
with WTP liquid effluents that would warrant future modifications of
the 200 Area ETF delisting.
The commenter also raised a concern about a lack of pilot scale
testing for WTP effluent. In particular the commenter states ``In the
case of 242-A condensate, condensates had been sampled, and surrogate
wastes were processed through pilot scale ETF treatment units in order
to provide an `up front' petition'' and ``No pilot scale processes have
been conducted for the current WTP EMF effluent. There is no pilot EMF
and no integrated pilot scale Direct Feed Low Activity Waste (DFLAW)
process treatment train. The integrated WTP `pilot scale' equipment
does not exist for DFLAW. Rather WTP itself is being built as a full-
scale pilot plant, with unknown and uncertain (but certain to be
expensive) results.''
Ecology and EPA acknowledge that the current proposed delisting
rule modification changes are based on projections, not full-scale
operations or demonstration testing. With respect to acetonitrile, the
proposed changes to the delisting rule are specifically targeted to
ensure an implementable mechanism is in place. This will allow
demonstration testing as necessary, to expand the treatability envelope
for acetonitrile. Therefore, before full-scale operation of the DFLAW
configuration of the WTP begins, Energy will have performed exactly the
type of direct demonstration that this comment speaks to. As discussed
more fully in the 2005 delisting modification action, the current 200-
Area ETF delisting is explicitly structured to accommodate new
constituents where such new constituents are within the treatment
capacity of ETF (as reflected in the waste-stream specific waste
processing strategy required by the delisting rule). New constituents
can be accepted for treatment in the 200 Area ETF without modification
of the delisting. For new constituents that would require changes to a
treatability envelope, the new demonstration testing mechanism in the
current proposal would be applied.
Secondary Wastes From the 200-Area ETF
The commenter raises multiple issues regarding secondary waste
associated with the 200-Area ETF system. In particular the commenter
states ``[a] defined secondary waste disposition path is needed for the
solids/brine produced by treatment of WTP EMF hot operations
effluent.'' And ``DOE has initiated an additional project to install
the capability to load-out brine from the ETF STT's concentrate tanks
into totes for shipment off-site. This project will mitigate brine
removal issues from the STT and expand the capacity of WTP EMF hot
operations effluent treated[.]''
Information in the proposed delisting docket notes that ETF brine
could be sent off-site for further treatment. (See RPP-RPT-62739, pages
35, 38, 39, and 108). While this may be a valid issue, secondary wastes
are not within the scope of the proposed modifications to the 200-Area
ETF delisting.
Addition of New Constituents
The commenter notes that Energy has identified multiple additional
constituents associated with liquid effluent from the WTP. In
particular, the commenter states ``[a]dditionally, RPP-RPT-60974 lists
constituents in the projected WTP EMF hot operations wastewater profile
that are not included in the delisting treatability envelope, including
2-hexanone, 2-butoxyethanol, acetate, glycolate, oxalate, boron, and
manganese. These additional constituents (and their associated limits)
will need to be added to the delisting approval treatability envelope.
A project is underway to complete this action.'' and ``EPA has noted
that acetonitrile is difficult to destroy. Will the yet undiscovered
other constituents be similarly difficult to destroy, potentially
leading to more `off-site' promises and off-site risks?''
Ecology and EPA agree that the enumerated constituents have been
identified by Energy. However, the mechanism established in the 2005
revisions of the ETF delisting, specifically the treatability group
concept, was established to address exactly this circumstance. (See
Condition (1)(b) of the current delisting). Ecology and EPA are
expecting a written request from Energy to modify Tables C-1 and C-2 in
the existing delisting, to incorporate these additional constituents.
Because treatment of these constituents is expected to be well within
the treatability envelope of the associated treatability group (to
which they will be
[[Page 50649]]
added), no change to the delisting rule itself is necessary.
Ecology and EPA have determined (based on their review of the
information provided by Energy regarding new constituents associated
with the WTP) that the methodology used by Energy in developing this
information is sound and defensible. There is no substantial risk of
unidentified constituents appearing in WTP liquid effluents that would
preclude acceptance of such wastes for treatment at the 200 Area ETF.
Ecology and EPA also note that the 2005 revision to the ETF delisting
include rigorous waste characterization and waste treatment plan
requirements prior to acceptance of any waste for treatment at the 200
Area ETF, ensuring that even in the remote instance that constituents
(or levels of constituents) which would cause a waste to be
unacceptable for treatment at ETF are identified prior to waste
receipt.
Shipment of Secondary Waste for Off-Site Treatment
The commenter also raised concerns regarding Energy's current
proposal to send secondary wastes from the ETF (brine, acetonitrile
concentrate) to an off-site treatment, storage or disposal facility. In
particular, the commenter states ``[a]ny tank-waste-related feeds to
LERF/ETF [Liquid Effluent Retention Facility/Effluent Treatment
Facility] and any brines produced as a result of the changing
`projections' of WTP waste compositions as described in the current
delisting petition, should be prohibited from off-site treatment. The
cradle to grave liability for this waste rests with DOE, and DOE should
not share it with a facility that has a poor track record and a poor
environmental location.'' and the second citation in the comment
discussed in the previous section ``Addition of new constituents''.
Regarding the risks associated with treatment of ETF secondary
wastes at off-site facilities, Ecology ensures that all such wastes are
treated, stored and disposed at approved facilities and in full
compliance with all dangerous waste regulations and applicable permits
in a manner fully protective of human health and the environment.
However, concerns related to treatment, storage or disposal of
secondary wastes are not subject to delisting and to this current
delisting rule modification proposal.
Lack of Direct Liquid Effluent Characterization
The commentor made several comments regarding a lack of direct
waste stream characterization and lack of pilot plant data. In
particular, the commenter stated ``[i]n the case of 242-A condensate,
condensates had been sampled, and surrogate wastes were processed
through pilot scale ETF treatment units in order to provide an `up
front' petition[]'' and ``[n]o pilot scale processes have been
conducted for the current WTP EMF effluent. There is no pilot EMF and
no integrated pilot scale DFLAW process treatment train. The integrated
WTP `pilot scale' equipment does not exist for DFLAW. Rather WTP itself
is being built as a full-scale pilot plant, with unknown and uncertain
(but certain to be expensive) results.''
Ecology and EPA acknowledge that the current delisting rule
modification changes are based on projections, not full-scale
operations or demonstration testing. With respect to acetonitrile, the
proposed changes to the delisting rule are specifically targeted to
ensure an implementable mechanism is in place to allow demonstration
testing as necessary to expand the treatability envelope for
acetonitrile. Therefore, before full-scale operation of the DFLAW
configuration of the WTP begins, Energy will have performed exactly the
type of direct demonstration noted in these comments. As discussed more
fully in the 2005 delisting modification action, the current 200-Area
ETF delisting is explicitly structured to accommodate new constituents-
where such new constituents are within the treatment capacity of ETF
(as reflected in the waste-stream specific waste processing strategy)
required by the delisting rule. Constituents can be accepted for
treatment in the 200 Area ETF without modification of the delisting.
For new constituents that would require changes to a treatability
envelope, the new demonstration testing mechanism in the current
proposal would be applied.
Alternate Treated Effluent Reuse
The commenter also raised an issue regarding alternate re-use
practices as documented in RPT-63053, page 19 (This is the engineering
report provided as Attachment 3 to the March 31, 2021 delisting
modification request, included in the docket). Alternate reuse
practices are provided for under Condition 7 of the current delisting,
which is not being changed under the current modification proposal.
Ecology and EPA understand that Energy will be seeking approval under
Condition 7 for expanded treated effluent reuse practices at a later
date. Approval of this change is outside of the current proposed
delisting modification.
The EPA is also making one grammatical clarification identified
after the regulatory amendment proposed rulemaking was published. The
EPA is modifying the last phrase of Condition (6)(c) originally worded
as ``that the Energy will be liable for Energy's reliance on the void
exclusion.'' to read ``. . .that Energy will be liable for Energy's
reliance on the voided exclusion.''
III. Final Rule
A. What are the terms of this exclusion?
EPA is finalizing Energy's requested amendments as proposed.
Conditions of the existing delisting not modified by this action remain
unchanged.
B. When is the delisting effective?
This rule is effective September 10, 2021. The Hazardous and Solid
Waste Amendments of 1984 amended section 3010 of RCRA, 42 U.S.C.
6930(b)(1), to allow rules to become effective in less than six months
when the regulated community does not need the six-month period to come
into compliance. This rule reduces rather than increases the existing
requirements and, therefore, is effective immediately upon publication
under the Administrative Procedures Act, pursuant to 5 U.S.C. 553(d).
C. How does this action affect the states?
This exclusion modification is being issued under the federal RCRA
delisting program. Therefore, only states subject to federal RCRA
delisting provisions would be affected. This exclusion is not effective
in states that have received authorization to make their own delisting
decisions. Moreover, the exclusion modifications may not be effective
in states having a dual system that includes federal RCRA requirements
and their own requirements. The EPA allows states to impose their own
regulatory requirements that are more stringent than EPA's, under
Section 3009 of RCRA. These more stringent requirements may include a
provision that prohibits a federally issued exclusion from taking
effect in the state. As noted in the notice of proposed rulemaking,
Ecology is expected to make a parallel delisting decision under their
separate state authority.
IV. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at <a href="http://www2.epa.gov/laws-regulations/laws-and-executive-orders">http://www2.epa.gov/laws-regulations/laws-and-executive-orders</a>.
[[Page 50650]]
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is exempt from review by the Office of Management and
Budget because it is a rule of particular applicability, not general
applicability. The action approves a modification of an existing
delisting petition under RCRA for the petitioned waste at a particular
facility.
B. Executive Order 13771: Reducing Regulations and Controlling
Regulatory Costs
This action is considered an Executive Order 13771 deregulatory
action. This final rule maintains meaningful burden reduction afforded
by the existing exclusion consistent with changes necessary to allow
management of liquid effluents expected from startup and operation of
Hanford's Waste Treatment and Immobilization Plant.
C. Paperwork Reduction Act
This action does not impose an information collection burden under
the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501
et seq.) because it only applies to a particular facility.
D. Regulatory Flexibility Act
Because this rule is of particular applicability relating to a
particular facility, it is not subject to the regulatory flexibility
provision of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.).
F. Unfunded Mandates Reform Act
This action does not contain any unfunded mandate as described in
the Unfunded Mandates Reform Act (2 U.S.C. 1531-1538) and does not
significantly or uniquely affect small governments. The action imposes
no new enforceable duty on any state, local, or tribal governments or
the private sector.
G. Executive Order 13132: Federalism
This action 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.
H. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications as specified in
Executive Order 13175. This action applies only to a particular
facility on non-tribal land. Thus, Executive Order 13175 does not apply
to this action.
I. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
This action is not subject to Executive Order 13045 because it is
not economically significant as defined in Executive Order 12866, and
because the EPA does not believe the environmental health or safety
risks addressed by this action present a disproportionate risk to
children.
J. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution or Use
This action is not subject to Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.
K. National Technology Transfer and Advancement Act
This action does not involve technical standards as described by
the National Technology Transfer and Advancement Act of 1995 (15 U.S.C.
272).
L. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
The EPA believes that this action does not have disproportionately
high or adverse human health or environmental effects on minority
populations, low-income populations, and/or indigenous peoples, as
specified in Executive Order 12898 (59 FR 7629, February 16, 1994). The
EPA has determined that this action will not have disproportionately
high or 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.
M. Congressional Review Act
This action is exempt from the Congressional Review Act (5 U.S.C.
801 et seq.) because it is a rule of particular applicability.

include, but is not
limited to,
engineering
calculations,
process modelling
results, or
performance data
provided by
equipment
manufacturers;
(ii) A demonstration
test plan
documenting the
following:
(A) The quantity and
characterization of
the waste stream to
be used in
conducting
demonstration
testing, and
information that
will be included in
the waste processing
strategy required by
Condition (1)(a)(ii)
for the
demonstration
testing. The test
plan shall document,
to a reasonable
degree of certainty,
that data gathered
from the
demonstration
testing will be
suitable for use in
modifying the
treatability
envelope pursuant to
Condition (1)(b).
The test plan may
include provisions
for ``spiking'' the
demonstration test
waste feed to ensure
that a waste feed
meeting the
requirements of the
test plan is
available;
[[Page 50652]]
(B) A sampling and
analysis plan with
supporting
systematic planning
documentation (e.g.,
Data Quality
Objectives) and with
an associated
Quality Assurance
Project Plan, for
all sampling and
analysis specific to
the demonstration
testing. A minimum
of four independent
sample sets over the
course of the
demonstration test
are required from
both the influent to
the 200 Area ETF and
the effluent to the
verification tanks;
(C) A schedule for
conducting the
demonstration
testing. The
demonstration
testing schedule may
be based on
functional criteria
in addition to or in
lieu of fixed
calendar dates. The
testing schedule may
contain
contingencies for
revising the test
plan should
additional testing
be required to
obtain the required
performance data
points.
Energy may not
commence
demonstration
testing until
written interim
approval is obtained
from the Regional
Administrator. The
effect of interim
approval shall be
limited to relief
from the requirement
of operating within
the treatability
envelope specified
in Tables C-1 and C-
2 of the November
29, 2001 delisting
petition, as
amended, during the
period of
demonstration
testing. Interim
approval shall
remain in effect
only for the
duration of the
demonstration
testing as
documented in the
required testing
schedule. Within 60
days following
completion of
demonstration
testing, or such
other time as may be
approved in writing
by the EPA, Energy
shall submit a
written completion
report documenting
analysis of data
gathered during the
demonstration test.
Energy may request
an extension of
interim approval for
the period of time
between completion
of the demonstration
testing and final
approval of the
modified
treatability
envelope. The EPA
may approve
amendments to the
demonstration test
plan, including the
associated schedule,
as necessary to
successfully
complete
demonstration
testing. The EPA's
written approval of
the completion
report shall be
considered approval
of the modified
treatability
envelope pursuant to
Condition (1)(b).

request by EPA or
the State of
Washington and made
available for
inspection. All data
must be accompanied
by a signed copy of
the following
certification
statement to attest
to the truth and
accuracy of the data
submitted:
``Under civil and

In the event that any
of this information
is determined by EPA
in its sole
discretion to be
false, inaccurate,
or incomplete, and
upon conveyance of
this fact to Energy,
I recognize and
agree that this
exclusion of waste
will be void as if
it never had effect
to the extent
directed by EPA and
that Energy will be
liable for Energy's
reliance on the
voided exclusion.''
