RECOMMENDATION TO PETITION FOR ADJUSTED STANDARD
NOW
 COMES the Illinois Environmental Protection Agency
 (“Illinois EPA”), by one of
its
 attorneys,
 John
 J.
 Kim,
 Assistant
 Counsel
 and
 Special
 Assistant
 Attorney
 General,
 and,
pursuant
 to
 35
 Ill.
 Adm.
 Code
 104.416,
 hereby
 submits
 a
 recommendation
 to
 the
 Illinois
Pollution
 Control
 Board
 (“Board”)
 in
 response to
 the petition
 for adjusted standard (“petition”)
filed by Waste Management ofIllinois,
 Inc.
 (“WMII”) (“Petitioner”).
 For reasons stated in
 detail
below,
 the
 Illinois
 EPA
 recommends
 that
 the
 Board
 deny
 the
 adjusted
 standard
 request.
 In
support ofthis recommendation, the Illinois EPA states as follows:
I.
 INTRODUCTION
The
 Petitioner
 is
 seeking
 an
 adjusted
 standard
 delisting
 a
 lime-conditioned
 filter
 cake
(“treatment
 residual”)
 that
 results
 from
 treatment
 at the
 Biological
 Liquid
 Treatment
 Center at
generated
 at
 WMII’s
 CID Recycling
 and Disposal
 Facility (“CID”).
 In
 its
 petition,
 WMII
 asks
the Board to
 incorporate
 a document
 (“Delisting Request”) previously submitted to
 the Board
 in
January 2005
 as part of a
 different
 adjusted
 standard proceeding (AS
 05-03).
 The Illinois
 EPA
does not object
 to this request, and has considered the Delisting Request as part ofpreparing this
recommendation.
1
To
 obtain
 a
 positive
 ruling
 from the Board,
 the Petitioner
 must
 satisfactorily
 address all
factors
 set
 forth
 in
 Section
 104.406
 of the Board’s
 procedural
 regulations
 (35
 111.
 Adm.
 Code
104.406) as well as in
 Section
 28.1(c) of the Illinois
 Environmental Protection
 Act
 (“Act”) (415
ILCS
 5/28.1(c)).
II.
 SECTION
 104.406 FACTORS
For
 the
 reasons
 more
 fully
 set
 forth
 below,
 the
 Illinois
 EPA
 does
 not
 believe
 the
Petitioner
 has
 satisfactorily provided
 all
 information
 and/or justification
 required
 by
 Section
104.406 ofthe Board’s procedural rules.
A.
 Section
 104.406(a)
—
 Standard from which adjusted
 standard is sought
The Illinois EPA does not take issue with the Petitioner’s statements on this topic.
B.
 Section
 104.406(b)
—
 Regulation of general applicability
The Illinois EPA does not take issue with
 the Petitioner’s
 statements on this topic.
C.
 Section 104.406(c)
 —
 Level of justification
The
 Illinois
 EPA does not
 take
 issue
 with
 the Petitioner’s
 statement as to
 the
 required
level ofjustification.
 However, the Illinois
 EPA does not
 believe that the justification has been
met, in
 that the Petitioner has not provided sufficient information and argumentto meet
 that level
ofjustification.
D.
 Section 104.406(d)
—
 Petitioner’s activities
The Illinois EPA does not take issue with
 the Petitioner’s statements on this
 topic.
E.
 Section
 104.406(e)
—
 Efforts necessary to comply
The Illinois EPA does not take issue with
 the Petitioner’s statements on this topic.
2
F.
 Section
 104.406(1)
—
 Proposed
 adjusted
 standard
The
 Illinois
 EPA does not
 believe the proposed adjusted standard should
 be
 granted by
the Board
 in
 its
 present
 form,
 as the Petitioner has not
 met
 the required level ofjustification
 to
warrant issuance ofthe adjusted standard.
G.
 Section
 104.406(g)
—
 Quantitative and qualitative
 impact on the environment
The Illinois
 EPA does
 not
 believe the Petitioner has presented
 a
 sufficient
 and
 complete
risk assessment in its petition
 and Delisting Request.
H.
 Section
 104.406(h)
—
 Justification of the proposed
 adjusted standard
The
 Illinois
 EPA
 does
 not
 believe
 the
 Petitioner
 has
 met
 the
 required
 level
 of
justification.’
 As the Petitioner noted, there are three criteria that must
 be satisfied, pursuant to
Section
 720.122 of Title
 35
 of the Illinois
 Administrative
 Code
 (35
 III.
 Adm.
 Code
 720.122).
The Illinois
 EPA
 agrees
 with
 the Petitioner
 that
 the
 first
 two
 criteria have been
 satisfactorily
addressed.
 It
 is
 the
 third
 criterion, that
 the petitioned
 waste
 not
 exhibit
 any
 other factors
 that
could cause the waste to be a hazardous waste, that the Illinois EPA finds has not been met.
To
 demonstrate
 compliance
 with
 the
 third
 criterion,
 the
 Petitioner
 preformed
 risk
assessment
 modeling
 in
 accordance with
 the EPA Delisting
 Program:
 Guidance Manual for the
Petitioner.
 Specifically,
 a risk
 assessment
 was conducted
 using
 the Delisting
 Risk
 Assessment
Software
 (“DRAS”)
 —
 Version
 2,
 which
 is
 the
 standard
 model
 used
 by
 the
 United
 States
Environmental
 Protection
 Agency
 (“USEPA”)
 for its
 hazardous waste
 delistings.
 The
 DRAS
model was used to
 model
 both
 a
 groundwater pathway and a surface pathway.
 Illinois
 EPA and
‘In addition to the concerns regarding the justification ofthe proposed adjusted standard, the
 copy of the
Delisting
 Request
 provided
 to
 the
 Illinois
 EPA
 by
 the
 Petitioner
 does
 not
 contain
 a
 signature
 on
 the
Certification Statement as
 found in
 Section
 2.0.7,
 p.
 5.
 If the original ofthe
 Delisting Request filed with
the Board does contain
 a signed statement, then there is
 no
 problem.
 However, the
 Illinois
 EPA requests
that
 the
 Board review
 the Certification
 Statement
 to check for a
 signature;
 if no
 signature
 is found,
 then
this omission (as otherwise required by
 35
 Ill.
 Adm.
 Code 720.1220)02))
 is another basis for the
 Illinois
EPA’s recommendation that
 the petition be denied.
3
USEPA
 have traditionally considered waste to be
 acceptable for delisting if the foil-carcinogenic
Hazard
 Index
 (“HI”)
 is
 less
 than
 1.0,
 and
 the
 carcinogenic
 risk
 is
 less
 than
 106.
 The DRAS
modeling conducted
 by
 WMII showed
 a
 HI of 0.02
 with
 carcinogenic
 risk of 1.53x10~for the
groundwater
 pathway; and
 a
 HI of 0.0552
 with
 a carcinogenic
 risk of l.83x106
 for the
 surface
pathway.
 WMII
 concludes that
 these
 risks
 are
 acceptable for delisting.
 However, there were
problems with
 the methodology used.
In
 Section
 7.5
 on
 page
 46
 of the Delisting
 Request,
 WMII indicates
 that
 several
 metal
parameters
 were
 excluded
 from
 calculation
 of the
 Hazard
 Index
 based
 on
 those
 constituents
appearing
 to
 be
 below
 background
 soil
 levels
 found
 in
 a
 United
 States
 Geological
 Survey
document.
 The background numbers identified in
 Table
 12 on
 page 46
 appear
 to
 be
 very
 high
compared to background concentrations found in Illinois as indicated in the “TACO” Rules at 35
III. Adm.
 Code 742, Appendix A,
 Table
 G.
 In fact, most of the numbers found in
 Table
 12
 are 2
or more orders of magnitude higher than the “Counties
 Within Metropolitan
 Statistical
 Areas”
column
 of
 35
 III.
 Adm.
 Code
 742,
 Appendix
 A,
 Table
 G.
 When
 compared
 to
 the
 TACO
background
 numbers,
 several
 of the constituents
 in
 the
 waste,
 which
 are
 excluded
 from
 the
calculation of the cumulative Hazard
 Index, are above background levels.
Of particular
 concern
 is
 arsenic,
 which
 was
 detected
 in
 the
 petitioned
 waste
 at
 a
concentration of 80
 mg/kg.
 The proposed “background” number for arsenic is
 97
 mg/kg.
 Since
the detected concentration
 is
 less
 than the “background”
 concentration, it was eliminated
 from
the cumulative
 Hazard
 Index
 calculation.
 However,
 a
 check of the TACO background numbers
shows that arsenic typically occurs in
 a range of 11.3
 mg/kg (non CMSA)
 to
 13
 mg/kg (CMSA).
Thus,
 arsenic
 does
 indeed
 appear
 in
 the
 waste
 higher
 than
 background,
 and
 should
definitely be included
 in the HI calculation.
 Note that the Hazard
 Quotient calculated
 for arsenic
4
(Table
 11)
 is
 2.26.
 It would
 cause the cumulative
 HI
 to
 exceed
 1.0
 by
 itself.
 Furthermore,
 the
practice ofexcluding
 a constituent because it is below “background” is not
 sound practice from
 a
risk-assessment
 standpoint.
 Regardless
 of whether the parameter
 is
 above or
 below
 naturally
occurring levels,
 it does contribute
 to
 the overall
 risk
 of the waste.
 The Illinois
 EPA does not
believe USEPA
 allows this practice
 in
 its
 review ofhazardous waste
 delistings,
 and
 accordingly
such practice should not be allowed in Illinois either.
 It appears as though the Petitioner soughta
reference
 document
 with
 very
 high
 background
 levels,
 at
 least
 as
 compared
 to
 levels
 more
readily
 accepted and
 utilized
 in
 Illinois.
 The prudent course
 to
 take would
 be
 to
 use the most
conservative
 levels when assigning background levels, and
 in this
 situation the TACO levels
 are
certainly more conservative
 and therefore should be used.
Another
 issue
 is that,
 as
 previously indicated, for purposes of delisting hazardous waste,
Illinois
 EPA
 and USEPA have traditionally considered a cancer risk
 of 106
 to be
 the maximum
acceptable risk.
 The petition repeatedly refers
 to an
 “acceptable range” for cancer risk of
 1
o4
to
106,
 and
 ultimately concludes that
 the results of 53x104
 (groundwater) and
 1.83x106
 (surface)
are
 acceptable.
 The Illinois
 EPA previously conveyed this
 concern
 to
 WMII
 in
 September of
2004.
 In response,
 WMII
 took
 the
 step of using
 the Pollutev6
 model
 to
 model
 a
 Subtitle
 D
disposal
 scenario rather than the unlined
 landfill assumed
 by the DRAS
 model.
 The assumption
in
 this
 modeling
 was
 that
 leachate
 from
 the
 waste
 was
 present
 at
 the
 maximum
 detected
concentrations at a depth of
 1
 foot
 above
 the liner system.
 The liner system
 modeled
 consisted
of a
 geomembrane
 liner overlaying
 3
 feet of clay.
 The concentrations directly below
 the liner
from this model
 were then input
 into the
 DRAS
 model
 as initial
 concentrations for modeling the
groundwater
 pathway.
 With
 this
 modification,
 the
 aggregate
 carcinogenic
 risk
 predicted was
reduced to
 1.91xl06, which
 is still
 in excess ofthe lo6cutoffnormally
 accepted.
5
Therefore,
 for the reasons set forth above, the Petitioner has not
 met the third criterion
 for
justification
 in
 that
 the methodology
 and
 assumptions
 used in
 the
 risk
 assessment
 were
 flawed.
The
 Board
 should
 conclude
 that
 the
 Petitioner
 has
 failed
 to
 justify
 the
 proposed
 adjusted
standard.
I.
 Section
 104.406(i)
—
 Consistency with federal law
The Illinois EPA does not
 take issue with the Petitioner’s statement on this
 topic.
J.
 Section 104.406(j)
—
 Hearing
The Illinois EPA does not
 take issue with
 the Petitioner’s statement on this topic.
K.
 Section
 104.406(k)
—
 Supporting documents
The Illinois EPA does not
 take issue with
 the Petitioner’s statements on this topic, except
to
 note
 that
 the concerns described above regarding the content
 and
 conclusions of parts
 of the
Delisting Request are incorporated here.
IV.
 SECTION 28.1(C) FACTORS
The Petitioner did not specifically address the four criteria listed
 in
 Section 28.1(c) ofthe
Act,
 and
 therefore
 the Illinois
 EPA cannot directly respond
 to
 what
 the Petitioner would
 have
offered
 to
 address the criteria.
 The Board
 should
 therefore
 find
 that,
 as to
 at least three of the
criteria, the Petitioner has failed to adequately prove the listed requirements.
A.
 Factors
 relating to Petitioner are different than those
 relied on by the Board
The
 Petitioner
 did
 not
 specifically
 address
 this
 criterion.
 The
 Illinois
 EPA
 can
 only
assume
 that
 the
 economic
 hardship described by
 the Petitioner if the waste
 in
 question
 is
 not
delisted
 would
 constitute
 the
 factor
 that
 is
 substantially
 and
 significantly
 different
 from
 the
factors relied on
 by
 the Board
 in
 adopting
 the
 general
 regulation.
 However, there seems
 little
doubt
 that
 the
 Board
 took
 economic
 factors
 into
 consideration
 when
 adopting
 the
 general
6
regulations.
 There
 is
 little
 else
 in
 the petition
 that
 could ostensibly be
 offered
 up
 to
 prove
 this
requirement.
B.
 Existence of factors that justify an
 adjusted standard
The Petitioner did
 demonstrate that there may be
 higher costs associated with compliance
alternatives.
 But, that
 demonstration alone does not validate the economic hardship factor itself,
and
 as noted above, that
 factor does not meet
 the requirement found in
 Section
 28.1 (c)(i) of the
Act.
C.
 Adverse environmental or health
 effects
As
 described
 in
 more
 detail
 above,
 the
 Illinois
 EPA
 identified
 flaws
 in
 the
 risk
assessment provided by the Petitioner
 and
 therefore the Petitioner has failed
 to
 adequately prove
that there will be no adverse health effects.
D.
 Consistency with federal law
The Illinois EPA
 does not take issue with the Petitioner’s statement on this
 topic.
7
V.
 CONCLUSION
WHEREFORE,
 for
 the
 reasons
 stated
 above,
 the
 Illinois
 EPA
 hereby
 respectfully
requests that the Board deny the Petitioner’s request for an adjusted standard.
