OPINION AND ORDER OF THE BOARD
 (by J. Theodore Meyer):
This
 matter
 is
 before
 the
 Board
 on
 petitioner
 Testor
Corporation’s
 (Testor)
 November
 23,
 1988
 petition
 for
 hearing.
Testor’s
 petition
 seeks
 review
 of
 its
 closure
 plan,
 which
 was
approved subject to conditions by respondent Illinois Environmental
Protection Agency
 (Agency).
 Testor specifically requests review
of conditions
 1,
 3,
 4,
 and
 8 as they relate to the deadline for
closure,
 the
 necessity
 of
 groundwater
 monitoring,
 and
 permit
requirements.
 A public hearing was held
 in Rockford, Illinois on
Nay 9,
 1989.
 Both parties have submitted briefs.
Background
Testor
 owns
 and
 operates
 a
 plant
 in
 Rockford,
 Illinois.
Operations
 at
 the
 plant
 include
 the
 formulation
 and
 mixing
 of
paints and
 adhesives
 used
 for
 hobby
 models,
 arts,
 and
 crafts.
Specific solvent blends for each type of paint are formulated
 in
the pump room,
 which was equipped with
 a 1-1/2” overflow pipe to
drain any spills of flammable liquid and prevent the accumulation
of explosive vapors
 in the pump room.1
 The pipe ran
 to
 a
 small
depression outside of the plant.
 On June 25,
 1985,
 approximately
50
 gallons of toluene spilled
 in the pump room when an
 employee
propped open a deadman safety switch.
 The toluene ran through the
floor drain and pipe to the small depression outside the building.
1The pipe,
 which was installed in 1952, was grouted closed in
1987.
1fl~-17

On October
 5,
 1987,
 Agency personnel collected
 soil samples
from the
 discharge
 area.
 These
 samples
 showed
 that
 the
 soil
beneath the discharge area was contaminated with several volatile
organic compounds
 (VOC), including toluene.
 The Agency informed
Testor of these results by letter dated November
 6,
 1987.
 Testor
responded that it did not believe that a closure pursuant to the
Resource Conservation and Recovery Act
 (RCRA)
 was necessary,
 but
that
 it wanted
 to
 work with
 the Agency
 to
 reach
 agreement
 on
cleaning up the discharge area.
 (Ex.
 32A.)
 Eventually,
 however,
Testor did submit a RCRA closure plan in April 1988.
 (Ex.
 3.)
 The
Agency disapproved that plan on July
 19,
 1988.
 (Ex.
 11.)
 After
meeting with the Agency,
 Testor submitted
 a revised closure plan
on August
 26,
 1988.
 (Ex.
 22.)
 The Agency approved this revised
plan on October
 26,
 1988,
 after adding
 several conditions.
 (Ex.
26.)
 Conditions
 1,
 3,
 4,
 and 8 of that approval are the subject
of this appeal.
Notion To Exclude Evidence
On July 24, 1989, the Agency filed a motion to exclude certain
evidence and testimony which was admitted by the hearing officer
at the May
 9 hearing
 in this matter.
 Testor filed
 a response to
this motion on August 2,
 1989.
 The Agency’s arguments in support
of
 its
 motion
 were
 reiterated
 in
 its
 brief,
 and Testor
 again
addressed the issue in its reply brief.
The
 Agency
 moves
 to
 exclude
 Exhibits
 323,
 33,
 and
 Group
Exhibit
 34,
 and all testimony based upon those
 exhibits,
 on the
grounds
 that
 those exhibits
 and testimony deal with
 events
 and
information
 gathered
 after
 the
 Agency
 issued
 the
 permit
 with
conditions on October 26, 1988.
 Exhibit 32B is an estimate of the
cost of the groundwater monitoring required by conditions
 3 and
 4
of the permit.
 This estimate was developed by Gregory Verret,
 an
engineer employed by Testor to develop its closure plan.
 Exhibit
33
 is
 a flow chart
 showing
 the estimated
 schedule
 for Testor’s
three treatment or disposal options,
 also created by Mr. Verret.
 Group Exhibit 34 contains three figures:
 Figure 2
 is a drawing of
the soil sampling locations2
 Figure
 3
 is an east—west geological
cross—section of the discharge area; and Figure 4 is a north—south
geological cross—section of the discharge area.
 In support of its
contention that these exhibits and testimony based upon them should
be
 excluded,
 the Agency points to
 35
 Ill.
 Adm.
 Code 705.101(c),
which
 states
 that
 “Board
 review
 of
 RCRA
 permit
 issuance
 or
denial..
.
is restricted to the record which was before the Agency
when the permit was issued.”
 This regulation also cites to Section
40(b)
 of the Environmental Protection Act (Act), which states that
hearings on RCRA permits ar~to be based tiexciusively on the record
before
 the
 Agency.”
 Ill.
 Rev.
 Stat.
 1987,
 ch.
 111-1/2,
 par.
1040(b).
 The Agency contends that all of the disputed exhibits
2 There is no Figure
 1
 in Exhibit 34.
1fl5
 13
3
were developed after the Agency’s October 1988 permitting decision,
and thus that none of the exhibits belong in “the record before the
Agency.”
In response,
 Testor
 first argues that the Agency has waived
its
 objections
 to
 Mr.
 Verret’s
 testimony
 which
 was
 based
 upon
Exhibits
 32B
 and
 33
 by
 failing
 to
 object
 to
 that testimony
 at
hearing.
 As for Exhibit 32B itself, Testor maintains that although
the document itself was prepared after the October 1988 decision,
it is not new material, but simply represents an expert opinion of
the cost of the groundwater monitoring
 conditions
 imposed by the
Agency.
 Testor contends that Exhibit 32B is reflective of what the
Agency,
 in its expertise, knew or should have known when it imposed
the condition.
 Testor argues that Exhibit 33
 is similar,
 in that
it
 reflects matters
 within the Agency’s
 expertise.
 Testor
 also
admits
 that
 Exhibit
 33
 did not
 exist
 on
 October
 26,
 1988,
 but
maintains that
 it
 could not have been prepared before
 that date
because Testor did not know what conditions would be imposed by the
Agency.
 Additionally, Testor contends that the three
 figures
 in
Exhibit
 34
 are
 admissible.
 Testor maintains
 that
 Figure
 2
 is
simply
 a
 graphic
 representation
 of
 the
 discharge
 area
 and
 the
boring locations, based upon information in Testor’s closure plan.
(Ex.
 3 at pp.6—10.)
 Testor admits that Figures 3 and
 4 of Exhibit
34 do
 include information which was not before the Agency,
 since
those figures are based upon actual testing of soil samples taken
after
 October
 26,
 1988.
 However,
 Testor
 asserts that
 they
 are
illustrative of the sampling process set forth in the closure plan,
and that much of the testimony regards that
 process,
 not actual
data.
The Board will grant the Agency’s motion to exclude evidence
and testimony
 for all exhibits and testimony except Figure
 2
 of
Exhibit 34.
 Initially, the Board must point out that the Agency’s
references
 to Section 705.101(c)
 is not directly
 on point.
 That
section
 refers
 to
 RCRA
 permit
 reviews,
 while
 the
 instant
 case
involves an appeal of conditions attached to a closure plan.
 These
are not the same thing.
 However,
 in a procedural
 sense the Board
does
 treat
 closure
 plan
 reviews
 in
 the
 same
 manner
 as
 permit
appeals,
 and
 the
 Board
 believes
 that
 Section
 705.101(c)
 is
persuasive
 authority in
 a
 closure plan
 review.
 That
 section
 is
quite clear that Board review of a RCRA permit issuance or denial
is restricted to the record which was before the Agency when the
permit was issued. It is well-settled that when reviewing an Agency
permit decision, the Board must determine whether the application,
as
 submitted
 to
 the
 Agency,
 demonstrates
 that
 issuance
 of
 the
permit without the contested conditions would not violate the Act
or
 Board
 regulations.

The Board
 finds that
 in reviewing a closure plan approval,
 that
105 19
4
review is limited to the record which was before the Agency when
it made the contested decision.
 Only Figure 2 of Exhibit 34, which
is based
 upon information contained
 in
 Testor’s application,
 is
admissible.
 The Board will not consider Exhibits
 32B,
 33,
 or
Figures
 3 and 4 of Exhibit
 34, nor any testimony based upon tho9
exhibits,
 in reaching its decision on the merits of this appeal.
The
 Board
 also
 notes
 that
 Exhibit
 32B,
 which
 is
 Mr.
 Verret’s
estimate
 of
 the
 cost
 of
 the
 groundwater
 monitoring,
 contains
information
 which
 is
 not relevant
 to the
 issue
 of
 whether
 the
application as submitted
 demonstrates that the plan without
 the
contested
 conditions
 would
 not
 violate
 the
 Act
 or
 Board
regulations.
 Cost
 is simply not
 a factor
 in that determination.
(See East Moline,
 slip.
 op. at 11—13.)
Applicability of Part 725 Rules
This
 permit
 appeal
 presents
 a
 number
 of
 issues
 for
 Board
decision.
 The first
 is whether the discharge area is properly a
“surface impoundment” as defined
 at
 35
 Ill.
 Adm.
 Code 720.110 so
that the RCRA closure rules, found at 35 Ill. Adm.
 Code 725, apply
to this clean—up.
 Testor contends that the discharge area was not
“designed
 to
 hold
 an
 accumulation
 of
 liquid
 wastes
 or
 wastes
containing
 free
 liquids”,
 as
 stated
 in the definition,
 but was
designed to receive spills of raw materials to avoid the potential
for an explosion in the pump room.
 The Agency points out, however,
that Testor has itself stated that the discharge area was designed
to
 receive
 spills
 of raw materials,
 and thus contends that
 the
discharge area was “designed” to hold liquid which would flow down
the drain.
 The Agency
 also maintains that the liquid which was
intended
 to
 flow down
 the pipe
 and into the discharge area was
indeed
 a
 “liquid waste”.
 The Board must agree with the Agency’s
assessment that the discharge area is a surface impoundment.
Second, Testor argues that the Part 725
PCRA
closure rules do
not
 apply
 to
 the
 remediation
 of
 the
 contamination
 beneath
 the
discharge
 area
 because
 it
 has
 never
 obtained
 interim
 status.
Testor points to the Board’s decision in Marley—Ingrid v. Illinois
Environmental Protection Agency, PCB 88-17
 (March 23, 1989), where
this Board held that “the closure and post—closure requirements of
35
 Ill.
 Adm.
 Code
 725.328
 can only operate
 within
 a regulatory
scheme
 which
 governs
 those
 facilities
 that
 are
 generally
 in
compliance with the interim status regulations.”
 (Marley-Ingrid,
March 23,
 1989,
 slip op.
 at
 p.
 8;
 emphasis in original.)
 Testor
states that
 it is clear that Testor never submitted a Part A or
The Board notes that in the recent decision in East Moline,
the appellate court affirmed the Board’s exclusion of evidence not
submitted to the Agency.
 Although East Moline involved a different
Board
 rule
 governing
 NPDES
 permit
 appeals
 (35
 Ill.
 Adm.
 Code
105.102(6) (8)),
 the Board believes that East Moline supports
 its
decision in the instant case.

Part B
RCRA
permit application and never certified compliance with
the
 interim
 status
 requirements
 for
 groundwater
 monitoring
 or
financial assurance.
 (Tr.
 45 and 48—49.)
 Thus,
 because it never
obtained interim status, Testor maintains that the Part 725 closure
rules are not applicable to this clean—up.
In response, the Agency first contends that Board regulations
show that a facility which did not obtain interim status
 is still
subject to the interim status regulations of Part
 725,
 including
the regulations on closure of hazardous waste units.
 The Agency
points to 35
 Ill. Adm.
 Code 700.104(b),
 which states:
b)
 The Board intends:
1)
 That, prior to RCRA permit issuance, all facilities
otherwise subject to Part 725 comply with its
requirements whether or not they have interim status
under 40 CFR Section 122.23.
 now
 40 CFR 270.70
The Agency maintains that this section means that all facilities
are
 subject
 to
 the
 interim
 status
 regulations
 until
 they
 have
received
 a
 permit
 which
 has
 been
 the
 subject
 of
 final
 Agency
action.
 The Agency states that such a permit would
 be
 a Part B
permit,
 and notes that Testor has never applied for or received
 a
Part
 B
 permit.
 The Agency
 also
 points
 to
 35
 Ill.
 Adm.
 Code
725.101(b):
b)
 The standards in this Part apply to
 .
 .
 .
those owners
and operators in existence on November
 19,
 1980,
 who
have failed to provide timely notification as required
by Section
 3010(a)
 of
RCRA,
 or failed to file Part A of
Permit Application as required by 40 CFR 270.10(e)
 and
(g)
 or 35
 Ill. Adm. Code 703.150 and 703.152.
 These
standards apply to all treatment,
 storage,
 or disposal
of hazardous waste at these facilities after November 19,
1980,
 except as specifically provided otherwise in this
Part or
 35 Ill. Adm.
 Code 721.
The
 Agency
 argues
 that
 this
 language
 unambiguously
 makes
 the
interim status regulations
 of
 Part
 725 applicable to
 facilities
that failed to provide timely notification or failed to file a Part
 A application, and points out that Testor did neither.
 Thus,
 the
Agency argues that Testor
 is indeed subject to the Part 725 rules
even though it never received interim status.
 The Agency states
that
 it would be absurd
 if Testor could avoid responsibility for
compliance with basic hazardous waste requirements
 by simply not
complying
 with
 those
 requirements.
 Finally,
 the Agency
 cites
United States v. Indiana Woodtreating Corp., 686 F. Supp. 218
 (S.D.
Indiana,
 1988),
 where
 a woodtreating
 plant which
 never
 obtained
interim
 status or a RCRA permit was required to comply with the
federal equivalent to Part 725
 (
 40 CFR Part 265).
105
 21
6
After careful consideration of the parties’ arguments and the
applicable statutes and regulations, the Board finds that Testor
is subject to the Part 725 rules
 even though
 it never obtained
interim status or a RCRA permit.
 A review of Sec~tion700.104(b),
which states that the Board intends the Part 725 rules to apply to
all facilities prior to RCRA permit issuance whether or not they
have
 obtained
 interim
 status,
 in
 conjunction
 with
 Section
725.101(b)
 convinces the Board that the plain language of these
rules
 states
 that Part 725
 applies
 to
 owners
 and operators of
facilities
 in existence on November 19,
 1980 who did not provide
timely notification or file a Part A permit application, and have
not received
 a Part B RCRA permit.
 It
 is undisputed that Testor
did not provide notification pursuant to Section 3010(a)
 of RCRA
and did not apply for either
 a Part A or a Part B permit.
 It
 is
also undisputed
 that Testor’s
 facility was
 in
 existence before
November
 19,
 1980.
 Therefore,
 applying
 Sections
 700.104(b)
 and
725.101(b)
 to Testor’s circumstances,
 it is obvious that Part 725
applies
 to
 Testor.
 The
 Board
 recognizes
 that
 this
 finding
contradicts the holding
 in Marley-Ingrid,
 but believes that this
result is mandated by the clear language of Sections 700.104(b) and
725.101(b).
 The Board notes that
 it did not have the benefit
 of
argument on the reading of these two sections together when making
its decision in Marley-Ingrid,
 since
 neither party
 in that case
ever brought
 Section
 700.104(b)
 to the Board’s
 attention.
 The
Board’s
 holding
 in
 Marley-Ingrid,
 that
 a
 facility which
 never
officially obtained interim status or substantially complied with
the interim status rules is not subject to Part 725, is overturned.
Condition
 1
Testor has appealed four
 of the conditions which the Agency
imposed
 on
 its approval
 of
 Testor’s closure
 plan.
 Condition
 1
requires Testor to complete all of its closure activities by June
1,
 1989,
 and to provide the Agency with certification of closure
within
 60 days
 of closure.
 This gives Testor approximately six
months to complete closure.
 Testor admits that this requirement
is
 based
 upon
 35
 Ill.
 Adrn.
 Code
 725.213(b),
 which
 requires
completion of closure activities within 180 days of approval of the
closure
 plan.
 Testor
 points
 out,
 however,
 that
 Section
725.2l3(b)(l)(A)
 allows the Agency to
 extend that period if the
owner demonstrates that the closure activities will,
 of necessity,
take longer than 180 days to complete.
 The closure schedule
 in
Testor’s application included 150 days to complete all activities
 up to the treatment or disposal
 of the contaminated
 soils.
 The
period of time needed for treatment or disposal of the soils was
indicated as “unknown”.
 (Ex.
 3 at pp. 23-4;
 Ex.
 22 at 24.)
 Testor
states
 that
 it
 could
 not
 reasonably
 be
 expected
 to
 choose
 a
treatment or disposal option until the contaminant concentrations,
volume, and treatability of the soils were determined.
 Therefore,
Testor’s application set forth four disposal or treatment options:
on—site treatment by mechanical aeration,
 biological degradation,
105 22
7
or vapor
 extraction,
 and off-site disposal
 at
 a RCRA
 landfill.~
(Ex.
 3
 at
 p.
 19;
 Ex.
 22
 at
 p.
 20.)
 Testor
 argues that
 it
 is
impossible to complete any of these options within the time period
established
 in Condition
 1,
 especially
 if contested Condition
 8
(which requires Testor to obtain a Part B RCRA permit to stockpile
excavated soils on-site prior to disposal)
 is upheld by the Board.
In response,
 the Agency points out that Testor’s application
 does not give any indication whatsoever
 as to how long treatment
or disposal of the soils may take.
 Thus,
 the Agency argues that
Testor did not make the required demonstration that more than 180
days
 is
 necessary
 to
 complete
 closure.
 Without
 a request
 for
extension and
 a demonstration
 of need,
 the Agency contends that
Section
 725.213(b)
 requires
 Testor
 to
 complete
 its
 closure
activities within 180 days.
 The Agency maintains that Condition
1 is necessary to assure that the closure plan did not violate the
Act or Board regulations.
As noted
 above, when reviewing an Agency permit decision,
the Board must determine whether the application,
 as submitted to
the Agency, demonstrates that issuance
 of the permit without the
contested
 conditions
 would
 not
 violate
 the
 Act
 or
 Board
regulations.
 Section
 725.213(b)
 clearly
 requires the owner
 or
operator
 to
 complete
 closure
 activities
 within
 180
 days
 after
approval
 of the closure
 plan.
 That
 section
 also
 requires
 the
Agency
 to approve
 an extension to that period
 if
 the
 owner
 or
operator demonstrates that closure activities will,
 of necessity,
take longer than
 180
 days
 to
 complete.
 The burden
 is
 clearly
placed
 upon the
 owner
 or
 operator
 to request
 an extension
 and
demonstrate that an extension
 is
 necessary.
 The only hint
 in
Testor’s application which
 could
 be construed as
 a
 request
 for
extension is a statement that “the
 ultimate disposal or treatment
of contaminated soil removed during this phase may require a longer
time period,
 depending
 on the time requirements
 for obtaining a
disposal permit or to complete on—site treatment
 of contaminated
soil.”
 (Ex.
 22
 at p.
 24.)
 The Board does not believe that this
statement was sufficient to be considered a request for extension
pursuant
 to
 Section 725.213(b).
 The Board
 is
 unable
 to
 find
 a
demonstration that closure would take more than 180 days anywhere
in
 Testor’s
 application,
 and
 thus
 must
 conclude
 that
 the
application did not demonstrate that Condition
 1 was not necessary
to avoid a violation of the Act or regulations.
 Additionally, the
only evidence in the record which supports Testor’s contention that
it is impossible to comply with the 180 day period is new evidence
and
 testimony
 by
 Mr.
 Verret,
 which
 the
 Board
 has
 excluded
 in
response
 to
 the
 Agency’s
 motion.
 Even
 if
 Testor
 had made
 a
sufficient
 request
 for
 an
 extension
 of
 the
 time
 period,
 its

 although the biological
 degradation
option
 is
 listed
 in Testor’s
 application,
 that
 option

mentioned by Testor at hearing or in post—hearing briefs.
inS 23
8
application failed
 to demonstrate that closure activities would
take more than 180 days.
 The Board must uphold the imposition of
Condition
 1.
 The Board
 notes,
 however,
 that Testor
 can still
request an extension of
the deadline pursuant to Section 725.213(b)
 and
 (c).
Conditions
 3 and 4
Testor also challenges the imposition of Conditions
 3 and 4.
Condition
 3 requires Testor to provide the Agency with
 a proposed
groundwater
 monitoring
 system
 that would
 demonstrate
 that
 the
groundwater quality
 in the saturated zone has not been adversely
affected
 by operation of the surface
 impoundment.
 Condition
 4
requires Testor
 to monitor
 the groundwater
 from
 its monitoring
wells
 in
 accordance
 with
 Subpart
 F
 of
 Part
 725
 until
 Testor
demonstrates
 that
 no
 release
 had
 occurred
 from
 the
 surface
impoundment.
 In its application,
 Testor had proposed collecting
soil
 samples
 at
 increasing
 depths
 to
 determine
 whether
contamination extended to the saturated zone.
 If so, Testor would
monitor the groundwater.
 If not, groundwater monitoring would not
be performed.
 (Ex.
 22 at p.
 15; Tr.
 pp. 79—89.)
Testor contends that the Board’s March
 23,
 1989 opinion
 in
Marley—Ingrid holds that groundwater monitoring is not necessarily
required for clean closure of a RCPA surface impoundment, although
equivalency
 will
 have
 to
 be demonstrated.
 Testor
 attacks
 the
testimony
 of
 Robert
 Carson
 of the Agency’s permit
 section,
 who
testified that there
 is no demonstration that an applicant could
make to avoid doing groundwater monitoring for
 a clean
 closure.
(Tr.
 at 192-193.)
 Testor maintains that Marley-Ingrid allows an
applicant to demonstrate equivalency, and argues that the sampling
program
 in
 its
 application
 is
 sufficient
 to
 do
 so
 if
 the
contamination has not reached the saturated
 zone.
The
 Agency
 responds
 by
 stating
 its
 belief
 that
 Testor’s
proposal for addressing groundwater contamination is inadequate to
demonstrate that the surface impoundment has not had an impact on
groundwater.
 The Agency contends that a clean closure under Part
725
 must consider groundwater,
 that
 it
 was
 not
 satisfied
 that
Testor’s
 proposal
 was
 adequate
 to
 show
 that
 groundwater
 was
unaffected by the surface impoundment,
 and that Conditions
 3
and
4 were
 included
 in the closure
 plan
 approval
 to
 correct
 those
inadequacies.
The Board agrees with Testor that,
 pursuant to our March 23,
1989 opinion in Marley-Ingrid, a facility which is subject to Part
725 and seeks to close by removal
 is not required as
 a matter of
law to comply with the Part 724 groundwater monitoring standards,
although such facilities must at some time demonstrate that they
have met the closure by removal
 standards of Part
 724 when that
facility seeks a determination of equivalency.
 As discussed above,
the surface impoundment at Testor’s facility
 is subject
 to Part
105•-2.4
9
725, and Testor proposes closure by removal.
 Thus,
 Testor is not
required as
 a matter of law to monitor the groundwater.
After
 a
 review
 of
 Testor’s
 application
 and
 the
 parties’
arguments,
 the Board finds that Testor’s application demonstrates
that neither the Act nor the regulations would be violated if the
permit was issued without Conditions
 3 and 4.
 In other words, the
Board believes that Testor’s proposed method
 of
 soil sampling to
 determine
 whether contamination has reached
 the saturated
 zone,
coupled with Testor’s commitment to perform groundwater monitoring
if contamination has reached the saturated
 zone,
 is sufficient to
prevent
 a
 violation
 of
 the
 Act
 or
 regulations.
 The
 Board
emphasizes, however, that this finding is based in large degree on
the
 fact
 that
 Testor’s
 soil
 sampling
 program
 includes
 all
constituents identified by the Agency’s sampling in the area,
 all
materials used at Testor’s plant,
 and a range of other chemicals,
and
 is not limited to the identified toluene release.
 The Board
also notes that after Testor completes this closure,
 it must either
obtain a post—closure care permit or demonstrate equivalency.
 In
other words,
 this
 is not the
 last time that the area groundwater
will
 be
 considered.
 The Agency
 is
 directed to
 issue
 the
 plan
approval without Conditions
 3
 and
 4,
 and to substitute
 Testor’s
proposed soil sampling and subsequent monitoring program.
Condition
 8
Condition
 8 requires Testor to obtain
a
RCRA
Part B
permit if
it
 stockpiles
 excavated
 soils
 on the ground
 prior
 to
 disposal.
Storage of hazardous waste in containers or tanks would be allowed
for
 90
 days
 without
 a
 permit
 if
 Testor
 complies
 with
 the
requirements of
 35 Ill.
 AdTn. Code 722.134.
 Testor challenges the
imposition of this condition, stating that it does not believe that
RCRA
storage or treatment permits are
required
 in this situation,
which
 Testor
 analogizes
 to
 clean—up pursuant
 to
 Section
 121
 of
CERCLA.
 Testor maintains
 that the Agency
 has not historically
required such permits for the clean—up of spills, and contends that
the imposition of the permit requirement does not serve any of the
purposes
 of the permit
 system.
 Testor
 argues
 that
 the
 permit
requirement actually undermines the goal of prompt remediation of
potential environmental threats, and maintains that CERCLA’s permit
exemption should apply here.
The Agency,
 in response, points out that Testor’s application
contains
 a plan to stockpile contaminated soils after excavation
from the surface
 impoundment.
 (Ex.
 22 at pp
 19-20.)
 The Agency
states
 that
 Condition
 8
 was
 included
 in
 the
 plan
 approval
 to
address violations of Board regulations which will occur
 if Testor
does indeed stockpile the
 soils.
 The Agency maintains that the
excavated soil
 is a hazardous waste when discarded
 (35
 Ill. Adm.
Code 721.133(d)), and that the act of stockpiling a hazardous waste
into piles
 is the creation of
 a waste pile which is
 a hazardous
waste
 management unit
 (35
 Ill.
 Adm.
 Code 721.110).
 The Agency
105 -25
10
contends that a
RCRA
permit is needed for any new hazardous waste
management
 unit,
 and
 that
 even
 a
 hazardous
 waste
 unit
 built
specifically as part of a closure process must be covered by a RCRA
permit.
 The Agency states that its position is not that Testor
must submit a Part B permit application as an absolute condition
to closure, but that Testor must obtain such a permit if it chooses
to stockpile the excavated soils.
 In sum, the Agency argues that
Condition 8
 is a necessary condition to the approved closure plan,
but that Condition
 8 does
 not require Testor to submit a Part B
application
 if
 they
 follow
 other
 storage
 options
 which
 do
 not
require a Part B permit.
The Board does not agree with the Agency that Condition 8
 is
necessary to assure
 that Testor’s closure
 of
 the area does not
violate the Act or Board regulations.
 The Board finds that the
condition is based upon an incorrect analysis of the situation. The
excavated soil does not become
 a hazardous waste when discarded,
as the Agency maintains;
 rather, the contaminated soil already is
a waste. The Board has held that the area in question is a surface
impoundment;
 therefore, the facility is a treatment, storage, and
disposal
 (TSD)
 facility.
 Section 722.134, which contains the 90—
day permit exemption, applies only to generators, not to owners and
operators of TSD facilities.
 The Board realizes that this facility
became a TSD facility “accidentally”,
 but this does not change the
fact that it
 is a TSD facility under the regulations.
 Condition
8
 is struck.
 However, striking the condition does not necessarily
force Testor
 to obtain
 a
RCRA
 storage permit.
 Testor would
 be
well—advised to be prepared to provide for prompt removal of the
waste as
 it
 is excavated.
Conclusion
In sum,
 the Board finds that the discharge area at Testor’s
facility
 is
 a surface impoundment,
 and that Testor’s facility
 is
subject to Part 725.
 Conditions
 1 is upheld, and Conditions
 3,
 4,
and 8 are reversed.
This
 Opinion constitutes the Board’s
 findings
 of
 fact and
conclusions of law in this matter.
ORDER
The closure plan approved by the Agency on October 26,
 1988
is affirmed in part and reversed in part.
 The Agency is directed
to issue the plan approval without Conditions
 3,
 4, and 8, and to
add Testor’s proposed soil
 sampling
 and
 subsequent groundwater
monitoring program as conditions to approval.
IT IS SO
ORDERED.
