BOARD OF SUPERVISORS OF

COUNTY,
Respondent.
DISSENTING OPINION (by
J.D. Dumelle):
My reasons for dissenting are:
 the obviously inadequate
legal notice regarding special wastes;
 the lack of due process
for East Peoria in its request for a hearing before this Board;
the majority’s position on prohibiting the County from considering
technical “subsurface” issues;
and
the admittedly “leaky landfill”
to be built over a major water supply aquifer.
The printed notice
 (Joint Exhibit
 6)
 is clearly deficient
in telling the public that special wastes were to be considered
for disposal at the site under review,
 All the notice says is
“for location approval of a solid waste disposal facility
will be used as a regional landfill.”
 This notice,
 prepared by
Waste Management of Illinois, Inc. does not mention that special
wastes are to be disposed of at the site.
The County Board Chairman,
 in his opening
 statement on
February 18,
 1982 describes
the
application as desiring approval
to dispose of “nonhazardous household,
 industrial and special
wastes.”
 This statement does not cure the printed notice
defect.
 Some of the public may have relied upon the printed
notice and thus not attended the hearing.
 The majority in its
opinion gives a warning to future applicants to be more precise
in notices.
 That does not cure the legal defect in this case.
At the very least,
 I would have disallowed permission to dispose
of special wastes at this site because of failure of the printed
notice to inform adequately.
The second defect in this proceeding was the majority’s
failure to grant East Peoria a hearing before the Board.
 In
the Board’s hearing on July 1,
 1982 the Hearing Officer only
allowed intervention at the end of the hearing.
 Thus East Peoria,
a city of 22,083,
 could not present any evidence at all because
of this late ruling
on
intervention,
 Its evidence might have
dealt with the adequacy of the record or the fundamental fairness
of
the County proceedings.
 Sufficient time
 (17
days)
 remained
for a hearing
 (see July
21
and July
26
orders and the dissent
filed by me).
 The acceptance of the offers of proof by the
majority is not sufficient.

The third problem in this case is the majority’s reading
of legislative intent to leave technical
 (translated as “subsur-
face”) matters to the Illinois Environmental Protection Agency
and to exclude the County from considering them.
 I do not read
criteria #2 in P.A.
 82—682 as saying that.
 Indeed a plain reading
shows the opposite intent.
 What could be plainer than “The facility
is so designed, located and proposed to be operated that the
public health,
 safety and welfare will be protected”
 (underlining
added)?
The leading case in Illinois to date of errors
 in landfill
“design and location”
 (to paraphrase the criterion cited above)
is the Wilsonville landfill,
 Here,
 a site was approved over
abandoned mine shafts,
 That fact is certainly germane to approval
or disapproval of a site.
 Yet the majority’s ruling on legis-
lative intent would prohibit an elected County Board from consi-
dering subsurface geology whether involving abandoned mine shafts
or earthquake faults or nearby potable water aquifers or the safety
and adequacy of a clay layer.
It can be argued that a County Board is not sufficiently expert
in hydrology and soils to decide issues concerning these areas.
At the same time, however, the County Board members are charged
with protecting public health and certainly with protecting
their county’s major water supply.
 Somewhere in the political
process the elected layman has to make technical decisions
 if
all of us are not to be governed by “experts”.
Lastly let us analyze those “subsurface” factors,
 The Waste
Management landfill will leak into the Sankoty aquifer.
 Joint
Exhibit 13A gives the time period for this to happen (Appendix IV).
Using
 a leachate percolation rate of 0.206 feet per year
 it would
take 50 years to penetrate the 10 feet of clay,
 And using 1.03
feet per year it would take
 90 more years to penetrate the average
90 feet of soil below the clay layer and above the Sankoty aquifer.
That totals to 140 years.
Two questions arise.
 How reliable are these time estimates?
How “clean” will be the leachate after attenuation and cationic
exchange by the clay layer?
The Waste Management witness,
 Dr. Murray M. McComas,
 an
expert hydrogeologist, testified on Feb.
 18,
 1982 at the County
hearing.
 He increased the flow rate through the clay layer by
50
 over that estimated by Patrick Engineering,
 Inc. in Joint
Exhibit 13A.
 He used 0.3 feet per year instead of 0.206 feet
per year
 (R.93).
 The time necessary to penetrate 10 feet of clay
then becomes
 33 years and not the 50 years referred to above.
Dr. McComas then states that the next layer to be encountered
is a “buried silt zone” with a transmission velocity of 0.002 feet
 per year (R.95).
 But Patrick Engineering had put it at 1.03 feet
per year or 515 times more porous!
 These major discrepancies by
experts from the same side are not explained.
47-498
A landfill above a major
 potaht~. water
 supply
 ought to be
“fail—safe”.
 If we use Dr~
McCc’n~
 ~:~uro of 0,3 feet per
 year
as
 the
 worst
 case
 condition
 we
 are
 :~uciq
 about 33
 years
 to
penetrate
 10
 feet
 of clay~ But the 1~feet of clay is the
“natural
 clay”
 layer.
 it
 is not placed by man,
 A
 sand
 lense
could
 occur
 in
 the
 bottom and negate the 1C feet of
 protection.
Testimony
 by
 a
 local
 consulting engineer,
 Robert
 M. Randolph,
points
 this
 out
 (R,203),
 If
 a sand lense has only
 two
 feet
 of
clay
 over
 it, then using Dr. McCornas~0~3feet per year rate,
the
 bottom
 integrity
 would
 be breached in 6.7 years,
 not
 33
 years!
How
 much
 protection
 would be given by the layer
 below
 the
 clay
also
 depends
 upon
 its
 integrity with reference to the
 sand
 lense
problem.
 The Patrick Engineering use of “average”
 depth
 of
 90
feet
 is
 not
 correct,
 The least depth
 (50 feet)
 should be used.
In
 summary
 the
 “140
 year” figure
 is probaby much
 too
 generous.
Leakage
 into
 the
 Sankoty
 Aquifer could well
 occur
 early
 in
 the
21st
 century,
The
 other
 question posed was the degree of attenuation of
organics
 and metals by a clay layer.
 Dr, McComas testified
that
 a
 layer
 of
 two feet is “more than adequate” for
 most
landfills anywhere
 in the country
 (R,103),
 However,
 the
 technical
literature has recently begun to discuss the deleterious effects
upon clay of certain organic solvents0
 Will the clay liner resist
this action and continue to attenuate or will
 it simply become much
 more porous?
 Will special wastes,
 which include oily sludges,
metal
 fines,
 and hot lime, overwhelm the attenuation capacity of
the clay?
 Certainly the County Board would wish
 to consider these
“subsurface” factors when making its decision.
Until other methods of refuse disposal such as recycling
and incineration are better developed,
 landfills will be needed.
But they should receive full scrutiny (surface and subsurface)
by elected public officials if they are to protect their consti-
tuents.
 And
 I believe that is the statutory intent.
I,
 Christan L. Moffett, hereby certify that the above
dissenting opinion was filed on
