 This report is the  result of a study initiated to determine  the  conceptual feasibility
 of disposing of solid wastes generated within Cook County, Illinois, by constructing
 a 1,000-foot-high mountain that would eventually be used for a number of recreational
 purposes.  A survey revealed that a mountain of this height  could  not be built anywhei
 in the county because of the serious air traffic problems  it would pose.  The site
 finally selected  is, therefore, 53 miles from Chicago's Loop and straddles the boundai
 between Will and  Grundy  Counties; it covers 11 square miles.  The  factors discussed ar
 evaluated  include waste  generation rates, site selection procedures, design problems
 (subsurface conditions,  structural stability, decomposition  products, cover material
 requirements, etc.), various forms and combinations of transportation, receiving and
 processing equipment, costs, financing, and administration.

 INTRODUCTION
The Ski Mountain study was initiated to deter-
mine the feasibility of disposing of solid  wastes
generated  within  the Cook  County  area  by
construction of a  1000 foot  high  mountain to
be used for outdoor recreation.

In line with Sanitary  District  policy of environ-
mental conservation,  certain  criteria were con-
sidered fundamental. These were:
       1.  Conservation of natural resources.
      2.  Protection of the environment against
          water and air pollution.
      3.  Provision  of a permanent method of
          refuse disposition.
The Ski  Mountain will  conserve resources  by
utilizing  discarded  materials in the construction
of a topographic feature of benefit to the entire
region. It  will provide needed outdoor facilities
for  recreation,  conservation  and  education.
Facilities will be available for  such winter sports
as skiing, tobogganing and  skating, and summer
sports such as camping, hiking and fishing. Wild
life  habitats will  be constructed and  preserved
and  nature  trails  will allow  observation  and
study of native plants  and animals.

All materials  incorporated  in  the mountain will
be  in  a  stable condition.  Organic  material will
be  reclaimed  or  returned   to  the  earth  where
natural decomposition can occur with  benefit
to  the soil.  On-site  incineration  will  be  pro-
hibited to  avoid pollution  of the atmosphere.

By   placing   only  solid   fill  and  previously
processed material  into the mountain, the con-
struction  will  become a  permanent method of
disposal that will eliminate  the hazard  of future
environmental pollution.
An estimate of present and future  quantities  of
materials discarded  in Cook County was devel-
oped from  population and  land use projections
of  the Northeastern  Illinois Planning Commis-
sion, data  furnished  by  other  public  agencies
and  information  from   private   firms.  Cook
County discards about 7  million tons annually.
About  6  million  tons  consist  of residential,
commercial and industrial refuse and demolition
debris presently collected  and disposed  of by
incineration  and landfill. The other one million
tons  consist  of power  plant  ashes, dredgings
from the waterways, street sweepings and similar
inert material  suitable for solid fill. Excavation
for  the proposed  Chicago area Deep  Tunnel
storm drainage project will produce about 200
million tons of dolomite  rock. Availability and
cost of alternatives will determine  the quantity
available for construction of the Ski Mountain.
However, even if all of this material is incorpor-
ated, completion of the Ski Mountain will take
several generations.

Potential Cook County sites were investigated  in
detail  and   it  was found  that  a  1000 foot
mountain anywhere in the  County would pose
serious  problems for air traffic.  The study area
was  then   broadened  and  sites   outside  the
County were considered.  Fourteen possible sites
were  thoroughly  analyzed  to  determine  their
suitability  for  Ski  Mountain. Site 10,  finally
selected  as  the basis  for  the engineering feasi-
bility study and site plan, is only 53 miles from
Chicago's Loop. It covers  over 11  square miles,
and has excellent accessibility due to its  location
between the  Illinois  River  and  I-80  and  its
proximity to two railroads.

PNORTH^
SITES  INVESTIGATED  FOR  SOLID  WASTE
     MOUNTAIN  AND  RECREATION  AREA

-------
The development of the Comprehensive Site Plan
for the Ski Mountain Project  was divided into
three  general areas  for study and  consideration:
   1.  The merging of construction  techniques
       and  related  problems into an integrated
       planning program.
   2.  The visual,  geological  and geographical
       merging of the mountain into  the Illinois
       landscape.
   3.  The development  of  the site  into  a
       multiple-use facility.
The program  for the  merging of the mountai
construction into  an  overall development pla
was divided into two basic areas of consideratioi
First, the transfer  of  the solid waste from tt
regional  transportation  network  to  the  loc
distribution system; and second, the on-site mov
ment and phased development.

-------
A  transfer point was located along the
river near the western boundary of the
site. This site  was selected  because of
its  potential  for  receiving  materials
from  three  modes of  transportation:
rail  movement,   road   vehicles   and
barge  transport   through  the  inland
waterway system,  and  because of an
existing  70  foot bluff which visually
isolates the  site  from  the surrounding
countryside.

-------
The  construction  techniques  to  be
used  and the patterns of  on-site move-
ment of the material were based on the
projected final  shape of the mountain
and its relationship to  the  overall site
plan.  In general,  the  mountain is plan-
ned to be constructed  from the south
towards the  north  with an ultimate
projected increase df 1000 feet over
existing elevations.
Throughout  the  development of  the
mountain facility, portions  of the site
will be made available  for recreational
use. The areas around the  mountain,
between the edges of  the site and the
base of the mountain construction will
be  made  immediately available for use
as a recreational facility. These  periph-
eral areas will form  visual barriers be-
tween the  on-site work  and the  sur-
rounding  countryside. As  the construc-
tion of the  mountain  moves  northward
and upward,  portions  of the original
construction areas will be  landscaped
and utilized.  By  the  time the  final
construction is completed  at  the north-
ern boundary of  the site, major por-
tions  of the facility will be in constant
use.

-------
 The development of a 1000 foot high mountain
 that  is integrated visually into the flat  Illinois
 topography  was  the  second  area  of  considera-
 tion.  The final  design  shape  of the mountain
 resulted from the synthesis of anticipated recrea-
 tional demands, construction techniques,  drain-
 age, landscape design, and topographic and  visual
 considerations.  The mountain  is designed  to be
 an  extension of the existing native landscaping,
 ravines  and   gullies  along  the waterway.  The
 result  is  a  visually pleasing mountain aestheti-
 cally  integrated into the Illinois topography and
designed for  maximum multiple use potential.

The development of the  Site  Plan  was divided
 into three main areas  of consideration: recrea-
tion,  conservation and natural science education.

The mountain was designed to provide a recrea-
tional facility which will afford people of all age
groups  and  interests an  opportunity to partici-
pate  in  a  variety  of  year-round  recreational
activities  in  an  atmosphere  which will  insure
maximum enjoyment.

The Ski Mountain Plan provides  for the conser-
vation of natural  resources and the development
of new, permanent open space areas. The Moun-
tain will be landscaped  to encourage the growth
of native grasses,  plants and trees, recreating the
indigenous  Illinois landscape  while providing a
natural habitat for a wide range  of animals  and
birds.  In addition, areas will  be  designed to
provide  natural habitats for  selected species of
animals and birds which are in danger of extinc-
tion. Specifically designated sites within densely
wooded  areas will  become sanctuaries for  larger
animals  such  as deer, fox, beaver  and badgers.
The entire site will be designed to act as a living
museum of native plants and wildlife.
The Ski  Mountain, with its programs of conser-
vation,  reconstruction and wildlife preservation,
will provide an ideal setting for the construction
of  a  natural  science   education  facility.  The
planting  of native plants and the  presence of
common and  rare  species of  native wildlife  will
provide  a  setting  for the education of all  age
groups, beginning  at the grammar  school level
and  progressing through sophisticated  graduate
research.
                                                     The site  was divided into three areas for  plan-
                                                     ning of ultimate use. Area No. 1 with  its  ideal
                                                     sun orientation, was designed as an active recrea-
                                                     tional   facility.  Area  No. 2  was designed  as a
                                                     conservation area and natural science education
                                                     facility,  and Area  No. 3  was  designed  as a
                                                     passive recreational  facility. Due to its proximity
                                                     to the receiving and  transfer point,  Area No. 3
                                                     would  be the last  area  developed for  ultimate
                                                     use.  Although  activities  are  primarily located
                                                     within the specific area designed for them, many
                                                     functions overlap creating a single, unified facility.

-------
Area  No. 1, the year-round  active  recreational
area  is visually  identifiable by its  three  bowl-
shaped areas, specifically formed and oriented to
capture and retain the winter snows. The three
bowl-shaped areas,  ranging  in vertical  height
from  300  to  500 feet on the south and up to
1000  feet  on the  north, provide skiing  trails
with varying degrees of difficulty.  In addition to
the skiing facility, which provides the site's most
dynamic recreational resource, the area  is plan-
ned to contain numerous  additional recreational
facilities.

The  lakes,  which provide the runoff, silt, and
pollution control during the construction phases,
are to be utilized as a  source  of water oriented
recreation  on  a year-round  basis.  During  the
warm  weather,  the  lakes are to  be used  for
swimming,  fishing, boating  and sailing.  Winter
activities  include ice fishing, ice  skating, speed
skating, ice hockey and ice boating. Pollution of
the lakes  will be prevented by constructing  the
mountain with essentially  stable material and by
collecting  water  which  percolates  through  the
fill  and  treating it  to remove or stabilize any
pollutants.  In addition, a  complete interception
system would be provided for collecting surface
runoff before it enters the  lakes. This would
include  surface ditching,  subsurface piping, and
retention reservoirs.  The interception and con-
trol system  would  prevent surface water from
entering directly into the lakes. Upon the detec-
tion of a nutrient within the  retention reservoir
the water would  be recycled over cropland for
nutrient removal.  In addition to the interception
system, a 100-foot wide barrier surrounding the
lakes would be developed,  including very deep-
rooted  trees and shrubs — its  purpose being the
interception  by the  root system  of  any high-
nutrient subsurface water.

The low hills surrounding the lakes are designed
for use  in  the winter time for  toboggan runs,
and the  most gently  sloping hills at the base of
the mountain become sledding runs.

A  complete  public  convenience   facility,   in-
cluding  specialty  shops,  restaurants and  lodge
facilities,  is  located  between  two  lakes at  the
base of  the  center bowl. This facility could be
expanded into a regionally  oriented  convention
and sports center  for family enjoyment within a
short distance of the Chicago  metropolitan area,
Across the lake from  the lodge and in the open
space at the base of the center bowl, a ski jump
facility  is planned to  attract national and inter-
national ski jump events.
Park facilities along the existing inland waterway
system  will  be expanded to  include  a  marina,
and  fishing and sightseeing charter  boats. The
road adjacent to the  waterway will be improved
to  facilitate pedestrian  and  automobile  sight-
seeing.  The  Channahon  Lock  on  the  former
Illinois and Michigan Canal will be maintained as
an historical landmark.

The  open fields and meadows around the base
of the  completed  mountain will be developed
into family recreation  areas which will  include
picnic  facilities, fields for sports such as base-
ball, football, and  soccer, and open spaces  for
model airplane flying.

-------

-------
The northern part of the site, designated as Area
No. 2,  is  designed as  a  large  and  significant
conservation area and natural  science education
facility. Automobiles  will be excluded from this
densely covered wilderness area.  The reservoirs
in this  area  will be developed  into marshes and
sloughs for use as natural  habitats for a variety
of native animals.  They  also will  provide  places
for birds to  rest  and feed  during  their  migra-
tions.

The sides of the mountain within this area will
be heavily landscaped with native  plants, ranging
from  prairie  grasses at the bottom of the slopes
through  small  shrubs and  trees and finally into
native forests.  They  will be specifically designed
to provide  habitats  for small  and large  animals
and birds which are native  to this region.

A natural science education facility  consisting of
a nature  center with museum  space, classrooms
and  laboratory facilities will  be  constructed at
the base of the mountain.  It will be utilized for
orientation   lectures  and   research conducted
within the area.  It will also be the starting point
for a series of hiking trails leading  through and
around specific areas within the site to amplify
the educational programs.

-------

-------
The area on the southwest portion of the moun-
tain  site,  designated  as   Area No. 3,  will  be
developed into a passive recreational facility.

This  site will  provide for family  camping,  in-
cluding facilities  for  camping trailers, cabins and
tents.  These facilities  will be  provided  in and
around the lakes and  up  on  the  mountain
slopes.  All  locations  will  include necessary san-
itary facilities.  Specific areas will be set aside for
institutional  use such as the Boy Scout Program.
The site will be honeycombed with equestrian,
bicycle and snowmobile trails for family use and
enjoyment.  Trails from these camping  facilities,
as well as  from other points,  will lead to  an
observation  point and restaurant complex at the
highest point on the mountain.

-------
The result of the three phase design approach is
a mountain that visually blends into the Illinois
topography and  provides  a multiple use recrea-
tional   and  educational  facility  for  all  the
residents of the Chicago metropolitan area.
                                                                                                  13

-------
 Feasibility  and  relative  cost of  methods  that
 might be used for transport  of materials to the
 Ski  Mountain  were examined and locations for
 transportation  terminals  in Cook County were
 designated.  Several  modes of transport will be
 feasible. Direct haul by  collection vehicles will
 be  most  economical  for materials  generated
 within  about 15  miles of  the site. Transfer via
 railroad or  large highway semitrailers  will be
 practical means for transporting residential, com-
 mercial and industrial  refuse from most of the
 fully developed areas of Cook County.  Barging
 will  be the best means  for  transporting heavy
 materials  such  as  ash,  rock, and demolition
 debris.
 A  mountain,  1000 feet  in height, will impose
 extremely   high  foundation  pressures  on   the
 underlying  formation  and within  the  fill itself,
 creating the  possibility  of  shear  failures;  and
 massive  slides.   Preliminary  site  investigations
 indicate that  the foundation  is  likely  to be
 adequate, but  little is known  concerning  the
 behavior of refuse  under  heavy  loadings.  For
 this  reason, refuse  will be processed  and only
 stable materials will be placed in the mountain.

 The  recommended plan envisages the receipt of
 residential,  commercial,   and  industrial  solid
 wastes  at   12  receiving  stations  within Cook
 County and processing  it for  separation  into
 organic  and inorganic  materials.  The  stable in-
 organic  materials  will  be delivered by  railroad
 and  placed  into  the Ski  Mountain along with
 power plant ash and Deep Tunnel rock delivered
 by barge.  The organic materials will be delivered
 by railroad, spread in thin  layers and tilled  into
 the land. A small part  of the organics could be
placed on the Ski Mountain site; however, up to
40,000  acres of  additional land  may  ultimately
be  required to  receive  organics.  The  humus
 produced by natural degradation of the organics
can  be left in  place  on  the  land or  can be
 removed and  placed on the Ski Mountain. Initial
 construction will be accomplished with normal
 earth-moving  machinery. As  the mountain  pro-
 gresses  in height, portable conveyors as used  to
 handle aggregate may be employed.

 The initial investment required to construct the
 transfer  stations,  purchase  the  transportation
 equipment,  purchase the land  and construction
 equipment  for  the Ski  Mountain and  provide
 necessary  technical  services  is  $275,500,000.
 Unit  cost will be $9.85  per  ton for residential,
 commercial  and industrial refuse delivered to the
 transfer stations. For rock, power plant ash and
 similar  material  delivered   to  barge  loading
 stations, the average unit cost will  be $1.21.

 There is no existing  agency  organized to  |>er-
 form  the proposed functions and  a  new agency
 will be required. The organization should be a
 state  or  regional agency  authorized by  statute.
 To permit the  agency to  function effectively,
 the  legislation  should  provide the power  of
 eminent  domain, the ability to  enter into long-
 term  contracts and  authority  to levy taxes

 I.   SOLID  WASTE  QUANTITIES
   The  quantities of various types of solid  waste generated in  Cook County
were estimated from  published  reports and  data furnished  by public agencies
and private firms  involved  in  the  collection and disposal  of  wastes.  Since
quantity records are not maintained on most of the solid waste  generated, the
estimates prepared for this study are  necessarily approximations.
   Since most solid wastes are highly compressible, quantities cannot be defined
by volume  alone. Therefore, estimates of compressible waste are expressed in
tons, which is the  most meaningful  measure of such material. Quantities of
wastes  of relatively  high and uniform density such as ash and rock can  be
measured satisfactorily in cubic yards.
   A.  SOLID  WASTE GENERATION FACTORS
   Within a  given  region,  the  production of  solid waste  is  determined pri-
marily  by  the  population  served  and  by  the commercial,  industrial and
governmental  activity  within the  community.  Employment  is  a significant
indicator of these  activities. The quantity  of  waste  actually  collected and
delivered to  central  disposal  facilities  may  be significantly  less  than the
quantity generated because of on-site disposal and recycling.

     1.   Population.    Projections  of residential refuse  quantities  for this
study  were based on population estimates  by the  Northeastern  Illinois Plan-
ning  Commission (NIPC)  for  1965,  1975,   1985,  and 1995.(1)  The  NIPC
population projections  for the City of Chicago and for Suburban Cook County
outside  the  City  of  Chicago  are  shown  in  Table 1.  The  population for
intermediate  years  was  projected  on a  straight  line  basis  between  NIPC
estimates.
   Unpublished NIPC working papers show population forecasts for each square
mile  in  suburban  Cook County. This population  distribution  was  used to
estimate  geographical distribution  of residential refuse generation in suburban
Cook County.

     3.   On-site Disposal.   Backyard burning of solid  waste is not permitted
in the City of Chicago. However, on-site incineration is extensively practiced by
institutions, industries, commercial firms  and apartment buildings.  It has been
estimated that approximately 25  per cent of the waste generated in the City of
Chicago  is disposed of by on-site  incineration/J) For  this  study  solid waste
incinerated on-site was considered commercial and industrial refuse.

   In  recognition of the increasing stringency and enforcement of air pollution
codes and the difficulties of meeting these  codes with  small incinerators, this
study  assumed  delivery  to central disposal facilities of most of the waste
presently burned in on-site incinerators.
   Much  of the  brick, stone,  concrete and  similar  inert solid waste  resulting
from  demolition of buildings and other structures is used to  fill basements and
to reclaim other land.  Some materials,  particularly  bricks,  are salvaged and
re-used. These are beneficial re-uses of waste which greatly reduce the  quantity
of such materials to be  hauled to,  and disposed of at, central disposal sites. It
was  assumed  for this study  that  most  inert solid  fill  wastes  resulting from
demolition work would  not be delivered to the  proposed solid waste mountain.
However, due to difficulty and  expense of separation, it is expected that some
inert  solid fill  materials  will be received in mixed loads  with  combustible
demolition wastes.


   B.   ESTIMATED SOLID WASTE GENERATION

     1.   Residential Solid Waste.   A 1966  study by the Chicago Department
of Air Pollution Control estimated that 1,372,000 tons of residential refuse was
collected  annually  from  Chicago's  3,550,000 inhabitants.(2) This is  equivalent
to 0.386  tons per capita per year,  or 2.11 pounds per  capita per  calendar day
(pcd) and  is  consistent with a median of 2.0 pcd of residential refuse collected
from  representative American cities as determined  by  a 1965  survey by the
American Public Works Association (APWA).(3)

   Table  3 shows the projected future collection of residential refuse  in both
Chicago  and  suburban Cook County based on projected population, per capita
collection  of  residential  refuse determined by the Department of Air Pollution

Control, and an  allowance of 2  per  pent  per  year increase  in the per capita

                       Commercial         320,000
                       Industrial           475,000

  The report estimated  annual on-site  incineration of  solid waste in  Chicago at
approximately 750,000  tons. Since backyard burning  of refuse is prohibited in
Chicago, it was assumed for this study that most solid  waste disposed of on-site
was  commercial or industrial waste in the same ratio as collected wastes. On
this  basis, total  1965 generation  of commercial and  industrial solid  waste in
Chicago was estimated as follows:

  Table 1-4 and Table 1-5 show  projected^ future quantities of commercial solid
wastes and industrial  solid  wastes,  respectively,  for  Chicago and  suburban
Cook County. Quantities for the  City of  Chicago were projected for an
annual increase of 2 per cent*of the  estimated  1965 quantities. Quantities for
suburban  Cook  County were  calculated by  applying  to the projected  com-
mercial  and   industrial  acreages  the estimated  1965  productions  per  acre
increased  at   the  rate  of  2 per cent* per  year.  Projected  commercial  and
industrial  refuse quantities by  square miles for suburban Cook County, based
on NIPC land use projections,  are shown in Appendix A.


     3.   Building  Demolition Debris.   Solid  waste resulting from demolition
of buildings for urban renewal, highway construction, obsolescence and other
reasons  is  a   major element in  the  solid waste  disposal problem in Cook
County.  Such wastes can be divided  into two categories with respect to their
potential for  disposal,  as follows.

       Solid fill materials.   This category  includes brick,  stone, con-
       crete,   earth  and similar solid  materials. These  wastes  are gen-
       erally   used to  fill basements of  demolished buildings or to
       reclaim land  within the  urban area;  in  addition, some bricks
       are  salvaged  for re-use. As these are the most  economical and
       beneficial disposal methods for such waste,  it is unlikely that a
       significant  fraction of the solid fill  demolition waste would be
       disposed of in a remote solid  waste  mountain.

       Combustible  materials.    This  category consists  principally  of
       lumber,  roofing  materials  and  other  combustible  building
       materials, but  may  also  include  plaster  and  some  bricks and
       other solid  till waste which cannot be separated economically
       from  combustibles,  Combustible  demolition  waste  is difficult
       to dispose of  because  unfJer present  conditions it  cannot  be
       incinerated and is  not accepted  in many  landfills.  Currently,
       these  wastes are landfilled;  but landfills within  Cook  County
       which  accept  combustible demolition  material are rapidly  ap-
       proaching depletion.

  It was  assumed that solid fill materials resulting from building  demolition
would  not be disposed of at the proposed  solid waste  mountain.  Therefore,
the quantity of  solid  fill materials was  not estimated.

  As no  records  of the quantity  of  demolition  waste are maintained,  the
annual quantity  of combustible demolition material was estimated from infor-
mation  furnished  by demolition contractors  and  public  agencies responsible
for removal of existing buildings and structures.  The estimated  average annual
demolition of structures  by  public  agencies  and  others  is  shown  in  the
following  tabulation.

-------
   Estimates  based  on  all structures demolished  by the Chicago Department
of Urban Renewal in  a  one year period indicate that the average structure
contains approximately  120  tons  of combustible  material.  On  this basis, the
estimated annual  quantity  of combustible  demolition material from Cook
County was calculated as follows:

       5,000 buildings/year x 120 tons/building = 600,000 tons/year

  The quantity  of combustible  building  demolition  waste is expected  to
fluctuate  appreciably from  year  to  year in  response to variations  in  demoli-
tion  activities.  An  average of 600,000 tons per year was  used  for  projection
of future  quantities.

     4.   Rock  From  Proposed  Deep  Tunnel Storm  Drainage  Project.  The
Metropolitan Sanitary  District of Greater Chicago, in a  letter dated Febru-
ary 5,  1970,  instructed  that this study consider spoil  from the proposed Deep
Tunnel Storm Drainage Project, as follows:
       Only  rock excavated  for the  underground  storage requirements
       of the project,  estimated as follows:

                Northside Area              11,200 acre-feet
                West-Southwest  Area        38,100 acre-feet
                Calumet  Area                6,160 acre-feet

       These volumes  of rock pan be  assumed to be delivered to the
       ground surface  at  the respective MSDGC wastewater treatment
       plant  in each area.
       These volumes  do not include excavation  for tunnels, primary
       treatment,  air chambers,  and other chambers. Rock excavated
       for such  facilities  may  be  omitted  for  the  purpose  of this
       study.

  Based on  an  in situ  density of  165 pounds per cubic foot, and  a density after
excavation of 120 pounds per cubic  foot,  the  weight  and volume  of rock
excavation for  the storage  requirements of the Deep Tunnel Project  are
estimated, as follows:

-------
                                  Cubic Yards           Tons
       Northside Area             24,840,000        40,200,000
       West-Southwest Area        84,500,000       136,900,000
       Calumet Area              13,660,000        22,130,000
       Total                      124,000,000       199,230,000

   It was  assumed that this rock would be delivered at a uniform rate  over a
10 year period starting in  1975.
     5.   Ash from Power Plants.      The  Commonwealth  Edison  Company
advised  that  it annually disposes  of about  1,000,000 tons of ashes and  other
waste by-products of the coal burned in furnaces for electric power generation.
Approximately  one-half  of this material is  sold for fill, concrete construction
and  additives, asphalt filler, apd road base  ingredient. The remaining 500,000
tons per year might be available for the solid waste mountain/1*
  Most  of the power generating  stations are located near the waterways and
about one-half of the available tonnage of  wastes could  be moved by  barge
without a prior truck haul. All  of the available wastes  could be moved to the
disposal sjte by truck or  rail.

     6.   Dredgings from Waterway.   The Corps of Engineers, Department of
the  Army, forecasts  approximate annual dredgings from  waterways  in  Cook
County  as follows:(2)
                                        Average Annual Accumulation

-------
   Maintenance  dredging on the waterways is generally  performed under con-
tract. The method of transporting dredged  material is  not specified and is left
to  the discretion  of the contractor.  Transporting to, and disposing of dredged
material  at, the  solid  waste  mountain  may  not be economically  feasible.
Disposal sites along  the waterways will undoubtedly be used in preference  to
the solid waste mountain so long as the former are available.
   Usually  material  from maintenance dredging has a  high water content and
must be  drained prior to  hauling  by truck  or other  normal  earth  moving
equipment. Acceptance of dredged material at the solid waste mountain site
would probably  require  the installation of a permanent conveying system for
moving the material from barges to dewatering lagoons. After dewatering, the
material could be  used for covering other refuse in the fill.

     7,   Screenings, Grit and Street  Sweepings.     Annual cubic yards  of
screenings  and  grit from the Sanitary  District's wastewater treatment plants and
street sweepings were estimated by Bauer( l > as follows:

            Based on assumed density of 2,000 pounds per cubic yard.


     8.   Autos.   A  total of 957,212 passenger autos and a total of 1,027,539
vehicles of  all types  were registered in  Cook  County in  1969. A recent study
by  the  U.S. Bureau  of Mines  indicates  the  number of autos scrapped in the
United  States  each  year  varies from 6.1  to 1.6 per cent of the  number of
registered autos.(2)  Applying  a 7 per cent  factor to the  Cook County  auto
registration  indicates  an annual abandonment  and junking rate of about 67,000
for passenger cars and 72,000 for all  types of vehicles.

  The Automotive Pounds  Section of the Chicago Police Department indicated
a total of 87,000 autos were towed to the Department's pounds during 1969.
Of  this total, about  37,000 had been  abandoned. The Cook  County Sheriff's
Police  Department  estimates  a total  of  about  5,000 abandoned  autos in
suburban Cook County. Additional junked cars are in wrecking yards.
  Recent advancements in the scrap  metal processing industry, principally the
development of large shredders, make it feasible to process old autos into high
grade, marketable scrap metal. Although collection and disposal of old autos is
a significant  problem  in Chicago  and  suburban  Cook  County,  the  major
elements of  the  problem are transportation, storage and legal processing prior
to delivery  to scrap  metal  processors.  Scrap metal  processors indicate  ample
capacity  in  the Chicago  area to process  all old autos  for re-use as high grade
scrap metal. Only the nonmetallic parts such  as glass,  fabric,  plastics,  and
rubber need be considered as solid wastes.
  The major effort with  regard to old  autos should  be directed toward getting
them to  the scrap metal  processors. The  metallic portions of  old autos should
not  be considered potential  material  for disposal in  the solid  waste  mountain.


     9.   Unit  Weights  of  Solid Wastes.   Unit  weights  of solid  wastes  are
significant in  the study  as  they influence  payload,  hauling costs, and  landfill
space requirements.  Unit weights used in  the  study are  shown in  Table  1-6.
These are estimated  average values based on observations and published data.
Substantial  variations from  the listed  average weights  can  be expected in
individual loads of compressible wastes. Unit weights  will also be affected by
moisture content.
  C.   SUMMARY OF PROJECTED SOLID WASTE QUANTITIES
  Table 1-7 shows the projected annual and cumulative quantities of solid waste
from  Cook  County to  1995. The projections  are  divided  into  two  general
categories of wastes:  (1) those containing a high proportion of decomposable
organic material, and  (2) those  consisting of relatively  inert  material  which
could be used for constructing relatively stable  fill.

   D.  WASTES TO  SKI MOUNTAIN
   It is not possible  to forecast accurately how much solid  waste from Cook
County would  be disposed  of at  the proposed mountain because there are
disposal   alternatives  presently available   and  others   which  may  become
available.
   The  City of  Chicago  owns and  operates three incinerator  plants  which
burn about 660,000  tons of refuse annually.  Chicago's new 1,600  ton-per-day
incinerator  plant, now  nearing completion, will increase  the  City's incinera-
tion capacity to  approximately 1,000,000 tons per year. Public incinerators
in Evanston and  Skokie and three private incinerator plants in Cook County
add  substantially  to  available incineration capacity. However,  the  future role
of existing  incinerator  plants  is uncertain.  Some of the plants  will require
costly  modifications  to  meet  the  air  pollution code  and their owners may
adopt  other disposal  alternatives in lieu of investing in such modifications.
   Current incineration costs are reported in  the range of $5  to $8  per  ton
of refuse  incinerated. These  costs can be expected  to escalate  due to increas-
ing  operating  expenses  and added  capital costs for air pollution  control.
Comparative costs will probably be a major consideration in decisions regard-
ing continued operation  of incinerator  plants versus disposal  at the mountain.
   Most of  the  solid waste  collected in Cook County and not incinerated  is
currently  disposed of in private landfills in the county and adjacent counties.
Due to the shorter  haul distance  from  collection areas, these  landfills will
unquestionably  provide lower  overall cost for refuse  disposal than  the pro-
posed  mountain.  Estimates  by  knowledgeable refuse  contractors  of  the
remaining life  of these  landfills range from  less than 10 years  to about 15
years.  A  representative of the  Chicago & Suburban Refuse Disposal Associa-
tion, whose members  reportedly operate  1,000  refuse  collection  vehicles in
the  Chicago area, forecast   that virtually  all  landfills  now  available to its
members  will be  filled within  10  years. The  Association  sees little possibility
of  additional private landfill  space  in the  Chicago area. As existing solid
waste  disposal  facilities  are  phased out,  increasing quantities  of wastes may
become available for  construction of  the Ski Mountain.
                                 I- 17

-------
   Rock  excavated  from  the  proposed Deep Tunnel project may find  markets
as concrete aggregate, road  base  material, solid  fill for construction projects,
or  other purposes. Therefore, it  is not known  what part, if any,  of the
estimated 200 million tons of Deep Tunnel rock would be disposed of at the
proposed mountain.
   Although  nearby  disposal  areas for  dredgings from  the  waterways are
difficult  to obtain,  their economic advantages will result  in their use, where
possible,  in  lieu  of the  proposed  mountain.  Hauling of refuse  by  rail  to
sanitary  landfills in remote coal strip mines offers the possibility of relatively
economical  and pollution-free  disposal  of  Cook County  solid  waste.  In
addition, it offers the side benefits of  removing the  disposal operation far
from  the metropolitan  area  to sparsely  populated regions where it  can  be
used  to  reclaim  virtually useless  land  for  beneficial use.  A  number  of
railroads and  private disposal  contractors are  actively  promoting such  disposal
systems.

 II.   SKI   MOUNTAIN  SITE


   A.  SITE CONSIDERATIONS
   The following basic factors were considered in investigation and evaluation of
 sites for the Ski Mountain:

               Civil Jurisdiction                Water Pollution Potential
               Size and Configuration          Drainage
               Land Use                       Accessibility
               State Regulations               Air Traffic
               Geology                        Land Cost


     1.  Civil  Jurisdiction.   Initially, it was considered essential  that the  site
 be in Cook County to minimize the cost of delivering solid wastes, to make  the
 ultimate recreation  facilities  readily accessible to the people living in Chicago
 and  Cook  County, and to place the site  as directly as possible under the civil
jurisdiction of the administrative agency  selected  or  established to operate  the
 disposal  and recreational facilities. In addition, in recognition of the widespread
 opposition of the general public to solid  waste disposal facilities, it was thought
 that Cook County  should, if possible, provide sites for disposal of its wastes
within its own boundaries. As the study progressed, however, it was found that
 a  1,000 foot  high  solid  waste mountain  in  Cook County was not feasible
because  of  serious conflict  with air  traffic.  The  Steering Committee  then
 directed  that site investigations be extended to areas in  Illinois  outside  Cook
County,  preferably  near  the  Illinois Waterway to obtain the advantage of low
 cost transportation by barge. It  was recognized that a regional or state agency
would probably   be  required to  administer  a facility located outside  Cook
County.

     2.   Size and Configuration.  A  mountain constructed to  a  height   of
 1,000 feet with a 4 to 1  average slope would require a minimum base width of
8,000  feet.  Peripheral buffer  strips  to  minimize  inconvenience to  adjacent
properties, and vacant areas for transportation, processing, and other ancillary
facilities  increase  the minimum  site dimension to approximately  2 miles, and
the minimum site area to  4 to 5 square miles.  A larger site would have  the
advantage  of  greater design  flexibility, greater capacity, more latitude   in
provision of  recreational facilities, and a better opportunity to  retain desirable
natural features such as drainage  areas  and tree cover.
                                 II - 1

-------
     3.  Land  Use.    Existing  man-made  structures  and  facilities  such  as
homes, commercial  and  industrial buildings,  churches,  schools,  cemeteries,
streets, highways,  railroads,  pipelines, and  power lines increase  the cost and
difficulty of acquiring  and developing land for a solid waste disposal facility, as
well as the initial  adverse impact of such  a facility on  the  local community.
Therefore, the search for sites was directed  primarily toward agricultural and
other relatively undeveloped land.

   Investigated sites were  evaluated for conformity with NIPC land use  plans
and preference was given to sites in proposed open space wedges.

   Added  consideration was given to sites adjacent to railroads, industrial zones,
park  lands, waterways,  and other land uses  which would  screen the disposal
operation  from  residential  and  commercial  areas.  Sites adjoining land  uses
which are complementary  to the ultimate recreational facilities of the mountain
were also favored.

     4.  State Regulations.   The  State of  Illinois  Environmental  Protection
Agency (formerly the  Department of Public Health) is  responsible for super-
vision  of operation and maintenance of refuse disposal sites and facilities in the
State.  Refuse disposal  sites and facilities must be registered with the Environ-
mental Protection Agency.

   Rules  and  Regulations  for  Refuse  Disposal Sites and Facilities promulgated
by the Department of Public Health in 1966 are given in Appendix B.

     5.  Geology.   Geology  influences the  suitability  of sites for the Ski
Mountain in three  important  respects.  First, a  disposal site should  be  located
where  ground water is not present  or where the  subsurface formations minimize
the possibility of landfill leachate entering usable aquifers in sufficient quantity
and  of such quality  as to cause pollution.  Second,  the subsurface formations
must  have the structural strength to support  a  fill 1,000 feet in  height. Third,
the physical characteristics and quantity of unconsolidated formations on the
site should provide  cover material adequate for the solid waste fill.

   Figure 11-1  is a map  of  the Northeastern Illinois Metropolitan Area indicating
the generalized geologic environment potentially unfavorable for refuse disposal.
Superimposed on the map are the sites within the Metropolitan Area that were
investigated for this report. With the  exception of Site 4, none of the sites are
in areas indicated to be potentially unfavorable.

     6.  Water Pollution  Potential.   Rain  water  and  ground  water  which
infiltrate  solid waste  fill  become  polluted  with bacterial  contaminants and
soluble organic matter and inorganic salts. If water enters a fill in excess of the
quantity required to saturate the solid wastes, the  excess water will flow out of
the  fill as  a   polluted leachate. Studies by  Hughes  found that in northeastern
Illinois precipitation is adequate to  saturate a landfill and produce leachate/l J
Landfill  leachate  can  cause  pollution of ground water and  surface  water  if
permitted to enter water supply sources without attenuation of the pollutants.

  The principal water supply  sources which might  be polluted by  leachate in
the area covered  by the site survey are the  sand and  gravel deposits of the
glacial drift and river  valleys,  and  the sandstone  and limestone formations of
the underlying bedrock. Both of these aquifers are used extensively for public
and  private water  supplies and are valuable natural resources  which  must be
protected from pollution.
  Fortunately,  much of the  study area lacks sand and gravel deposits and the
bedrock aquifer is  protected  by a thick cover of relatively impermeable glacial
till  or lake  deposits, or both. These materials consist principally of pebbly clay
and silts which do not yield  water  to wells and which retard the  movement of
water into and between aquifers.  In some areas the top stratum  of bedrock is
shale, which also retards movement of ground water.
  The principal criteria by which sites were  evaluated for suitability  from the
standpoint of  preventing water pollution were those stated  by Cartwright and
Sherman :^2*

       Sanitary landfills should be located  in relatively impermeable or
   slowly permeable material so  that movement of  refuse leachate will
   be retarded. Clay,  shale,  silt,  and glacial  till are the most  common
   materials for filtering  out  the biologic organisms  of leachate. Sites
   where sand and gravel occur are generally  unsuitable  for  refuse
   disposal  because of their high permeability.
       A  minimum  of 30 feet  of  relatively impermeable  material  is
   usually required  between the  base of a landfill  and the shallowest

   aquifer.   In  general,  this  means that  approximately  50  feet  of
   favorable material is needed for a satisfactory site. A thickness of 50
   feet  permits  trenching to  a depth  of 20  feet, with  30  feet  of
   material still  in  place  for aquifer protection. If the refuse is to be
   covered  at  land  surface,   without  excavation,  then  30  feet  of
   relatively impermeable  material would be satisfactory.
       In areas where the glacial drift or other unconsolidated deposits
   are less  than  30 feet thick, the nature of the  underlying rock must
   be considered in appraising a landfill  site. If the bedrock is one of
   the  relatively  thick shale formations  that occur widely in  Illinois,
   landfill  operations might be permissible. If the  bedrock is creviced
   limestone  or  porous sandstone,  both of which serve as  aquifers for
   shallow  wells, a sanitaiy landfill in the thin overburden would  not
   be considered advisable.

     7   Drainage.   The  extensive area and steep side slopes of the mountain
will  result  in  high  volume, rapid  runoff of  precipitation,  which  must  be
accommodated by the drainage courses serving  the  site. The mountain should
not obstruct major  water  courses and, for that reason, should be located in the
upper reaches  of  a  drainage course so that runoff from outside areas  will not
flow through the site.

     8.   Accessibility and  Haul Distance.   Transportation  is a major factor in
the cost  of solid  waste disposal a'nd a high volume of refuse hauling traffic is a
potential  cause  of  inconvenience  to  the  public;  therefore,  transportation
accessibility from the area of  production is an important consideration in the
selection of disposal sites.  To  minimize transportation cost, the  site should be
as close  as possible to the area  of production  and accessible via transport
systems capable of  moving large volumes without causing  significant  inconve-
nience to the public.
   Because  the optimum method of transportation may  vary with the type of
waste and  the  location of the  production area, the site should be accessible by
several  feasible modes  of transportation.  In the  Chicago area the  existing
transportation  systems include  highways, railroads,  and the Illinois Waterway.
Good  access  via  highways is  essential  because  trucking   will  be the  most
practical hauling method for some portions of Cook  County and for most of the
area  outside Cook County  that might be served.
                                 II-4

-------
   Access via railroads  and the Waterway may  be particularly advantageous for
 transporting  the  large quantities  of  deep  tunnel  rock,  power  plant ash,
 incinerator residue,  and  similar high  density nonputrescibles which  do not
 require  prompt  delivery  and  disposal  for  protection  of public health and
 prevention of nuisance.

     9.  Air Traffic.   The high volume of air traffic at O'Hare, Midway, and
 other  Chicago  area  airports,  together  with  the  1,000  foot  height  of  the
 proposed mountain posed  a unique site problem - conflict with air traffic.

   Prospective sites were reviewed with  the Chicago Area Office  of the Federal
 Aviation Administration (FAA) for possible conflicts with air traffic. The FAA
 advised that a 1,000 foot high structure at any of the proposed sites in Cook
 County  would  seriously  conflict with  Instrument Flight  Rules  (IFR) traffic.
 The conflict with existing traffic would be most serious for sites in  southwest
 Cook County. In  addition, a mountain  in southwest  Cook County could have
 adverse effects on a  future major airport which may be constructed  southwest
 of Chicago.

   The FAA further  advised that a structure 500  feet or  more in  height located
 within 2 miles of a major  highway, railroad, river or similar topographic feature
 used as a visual aid to navigation could have an adverse  effect on Visual Flight
 Rules (VFR) operations. A substantial adverse  effect would result from such a
 structure in  western  or southwestern Cook County due to  the heavy volume  of
 small aircraft traffic on VFR  navigation to  and  from airports in the Chicago
 Metropolitan area  and outlying  airports.

   The FAA  advised  that,  in general, a  location west  of Cook County,  more
 than 40  miles from  O'Hare Airport and  more  than 6  miles from local airports
 would  have relatively  little  adverse effect  on  aeronautical  operations  and
 procedures in the Chicago  Metropolitan Area.  VFR traffic is lighter over remote
 areas and the adverse effect of  a 1,000-foot high mountain would be  much less
 severe than for the same structure in Cook County.

   The  FAA  reviews  of  prospective sites were  conducted  within  the  FAA
organization  and were  not circularized  to other aviation  interests.  The  FAA
requests  that it be notified when plans for the mountain become definite.  They
will then initiate a full aeronautical survey, including circularization to aviation
interests, and issue an official  airspace determination.
                                 II -5

-------
     10.  Land Cost.   Land cost will be  a  major factor in the initial capital
requirement  of the  Ski  Mountain  project  due  to the large area required and
competing demands for the land.

   Recent major land acquisitions  in  the general  vicinity of  prospective sites
suggest raw  land costs in the range of $3,500  to $4,500 per acre  for  land in
southwest Cook County arid $700  to  $1,600  per acre for farm land comprising
a site  outside Cook  County. Due to  the  existing  estate type development and
demand for land for  high cost residential development, sites  in northwest Cook
County are expected to cost in the  range of $10,000 to $15,000  per acre.

  Within  the indicated price range of sites considered, land cost alone should
not be a dominant factor in site evaluation since  the distance  that solid wastes
must  be transported  may have  a much greater effect on  the overall cost of
disposal.


  B.   SITE  INVESTIGATIONS

     1.   Sites in Southwest Cook County.    Investigations were guided by the
site considerations  discussed previously,  and  included the following principal
steps:
       • A thorough  survey was made of  topographic maps and N1PC
         land  use  plans to locate sites  appearing to meet the  estab-
         lished criteria.

       • On-site inspections were made of sites selected from the map
         survey to determine existing land  use, development, and other
         visible site conditions.

       • Generalized  geological  and  ground  water conditions  of  the
         sites were determined  from  published reports and conferences
         with  personnel  of the Illinois State  Geological Survey, Naper-
         ville office.

       • Information  on  approximate land values was obtained from
         public agencies  which had  recently  purchased land  in  the
         vicinity of prospective sites.

       • Inquiries  were  made  of  utility  companies  regarding  the
         presence and approximate  relocation costs of existing pipe-
         lines,  power lines, cables,  and other major utilities  on  the
         sites.
                                 II - 6

-------
       •  Prospective sites were discussed with representatives of govern-
          mental  agencies to  ascertain  the  effects  of a solid  waste
          mountain  and recreation area  on existing and proposed land
          uses  of the agency.  Agencies contacted included the State
          Division of Highways, Cook County Forest Preserve  District,
          Northeastern  Illinois  Planning Commission, Federal Aviation
          Administration, City of Chicago Aviation Department, and the
          Cook County Council of Governments.

   From  the  initial investigation,  five  sites  in the southwest  part  of Cook
County,  Sites 1  through 5 pn Figure 11-2, were considered  to  offer  the best
possibilities for  a 1,000-foot  high Ski  Mountain  and recreation  area  in Cook
County.  Results of the initial investigations were reported to the Ski Mountain
Steering  Committee  October 22, 1969. A copy of the report is in Appendix C.

   The report stated that, although the  sites presented were considered to have
the best  potential, it was doubtful that any of the sites could be  acquired over
the objections of  the public and the many public and semipublic agencies that
would be affected by an operation of the magnitude proposed.

   The possibility  of a site outside Cook County was discussed  by the Steering
Committee and  rejected because of opposition encountered by  MSDGC in  its
effort  to  acquire  land for sludge disposal outside  the County.  The committee
decided that  the site should  remain in Cook  County and that Site 5,  primarily
because of its varied  transportation  possibilities, should be the basis of the
study.

   In  proceeding  with  detailed  investigation of Site 5,  a request  was made to
the FAA  for an aeronautical review of the site. Based on its review,  the FAA
advised that  the proposed 1,000-foot mountain at Site 5 or any of the other
sites in Southwest Cook County would  have  a substantial adverse effect upon
aeronautical  operations  and  procedures in  the  Chicago  Metropolitan  Area.
Pertinent correspondence and conference memoranda are in  Appendix D.

     2.  Sites in  Northwest Cook County.    In  consideration  of the major
interference with  air traffic in  southwest  Cook  County,  the  Steering Com-
mittee, on March  13, 1970,  directed  that investigations be made  and a report
presented  on:
       • The feasibility of a  mountain  500  feet or less in height at
         SiteS.
                                 II-7

-------
       • Sites  in  northwest  Cook  County that could accommodate a
         500 foot + mountain.

       • The nearest  locations  in  Illinois where  a 1,000  foot  high
         mountain would not conflict significantly with air traffic.

  In  compliance with this directive, Sites 5 (Revised) through 9,  shown on
Figure 11-2, were investigated and reported on to the Steering Committee on
April  24,  1970.  The  investigation  disclosed that  Sites 6 through 9  could
accommodate a  500 foot high mountain; Site 5 could accommodate only a 350
foot mountain without interfering with  air traffic; and none  of the sites could
accommodate a  1,000 foot mountain.  A copy of  the  report to  the  Steering
Committee is in  Appendix E.

  The Steering Committee accepted the report and  directed  that  sites outside
Cook County along the Illinois Waterway be investigated.

     3.   Sites Outside Cook  County.   A report on investigations of potential
sites outside  Cook  County along the Illinois  Waterway  was  submitted to  the
Steering Committee on May 27, 1970. A copy of the report  is in  Appendix F.
Locations  of the sites investigated, Sites 10 through   14,  are  indicated  on
Figure 11-2.

  The  Steering  Committee selected  Site  10  primarily  because  of its  trans-
portation possibilities, isolation from residential development,  and proximity to
Cook County, and directed that the study be completed, based on this site.
  C.   SITE 10
  A more detailed evaluation  of Site 10 was then made for the Ski Mountain
Steering Committee. Figure II-3 is a topographic map of Site 10.

     1.   Civil  Jurisdiction.  Site 10 straddles the county line between Grundy
and  Will  counties  and   is outside   the  civil jurisdiction of Cook  County
governmental agencies. The MSDGC,  which might have been the logical choice
as management agency for a metropolitan system located in Cook County, does
not have the power of eminent domain outside Cook County.  Since power to
acquire land will be a requisite, it is doubtful that MSDGC or any other Cook
County governmental agency  could  be  the administrative  agency  for  the
facility.

     2.  Size  and  Configuration.   Site  10  extends about 4  miles in  the
north-south and east-west directions and comprises approximately 7,300  acres.
The site is large enough  to accommodate a 1,000 foot high mountain and, in
addition,  provide generous setbacks  and protective  buffers  around the  oper-
ation with enough space for recreation, nature areas, and other facilities.

   The  proposed mountain configuration  shown  on Figure II-4 would accom-
modate approximately 1.7 million acre-feet of fill.

     3.  Land Use.   The bulk  of Site  10 is agricultural land;  however,  a
suburban development of approximately 100 homes exists on the eastern edge
of  the  site  near U.S. Highway 6. Along  the  eastern and southern edges,  the
Illinois  and  Michigan Canal lies between the site and the north bank of the Des
Plaines  and Illinois  Rivers. Although no  longer used, the canal is  fairly well
preserved  and  conceivably  could  be  retained  and  incorporated  with  the
Channahon State Park which occupies the  southern tip of the site.

   The  Du  Page,  Des  Plaines  and  Illinois  Rivers  bordering the  eastern and
southern perimeter  of the site  provide excellent buffer zones to minimize  the
impact  of  the operation  on adjacent  properties. Much  of the land  on  the
opposite side  of the  Des  Plaines and Illinois Rivers is dedicated to conservation
use and would complement the  ultimate recreational use of the mountain.

   The  Elgin,  Joliet  &  Eastern  Railroad track  forms  the  western boundary of
the site and extensive industrial development is occurring immediately west of
the railroad. This development  and the railroad will serve as a buffer zone west
of the site.
  With the  exception  of people  living on  the  site,   the  communities of
Channahon and Minooka  are the only major  existing developments which might
feel a significant impact from  the operation.  For many years this impact, if any
resulted, would be due primarily to increased highway traffic.

   U.S.  Highway 6,  which  crosses  the  site,  would  ultimately have to  be
abandoned or  relocated. Other roads on the site are of minor significance.

  Three gas  lines,  two  electric  power transmission  lines and a  microwave
transmission path  traverse the site.  All  of these utilities would  require reloca-
tion. Additional electric power transmission lines across the site are planned.
                                 II-9

-------
     4.   State Regulations.   Preliminary data regarding Site 10  and the pro-
posed  mountain  were  submitted  to  the  State  Environmental  Protection
Agency  for  review,  Cppies  of  pertinent  correspondence  with  the  State
Environmental Agency are in Appendix G.

     5.   Geology.   A   preliminary  geological  review  and  report,  based on
published  data, was made  of  Site 10  by  the  firm  of Woodward-Clyde &
Associates. The Illinois  State Geological  Survey  submitted a letter report on
the hydrogeology  of Site 10 to the Illinois Environmental Protection Agency,
on August 31,1970. Copies of the report and  letter are  in Appendix G.

  No  borings were  performed  for  this study.  However,  available geologic
literature indicates tha,t Site 10 is underlain by  bedrock  of the Maquoketa
formation  approximately 80 to 90 feet in  thickness.  Glacial deposits 50 to
100  feet thick cover most of the  bedrock, and these, in turn, are overlain by
thin  lake deposits. A generalized  geological  cross section of Site 10 is shown
on Figure II-5.

  The Maquoketa formation  is reported to  consist  mainly  of shale  with
interbedded limestone or dolomite and, generally, it  does not produce ground
water.  However, in this area  the  formation is  mostly  dolomite rather  than
shale.  Water  supplies are  obtained  from wells  finished  in  the Maquoketa
formation, the underlying Galena-Platteville  dolomite and  the St. Peter sand-
stone.  Public  water supply  wells  within  the fill  area,  if any exist, could be
replaced  with wells outside  the fill  drilled into the  St. Peter sandstone which
is the most productive  formation/'}
  The glacial deposits  are expected  to be predominantly a relatively  imper-
vious silty clay till; however,  significant  quantities  of  pervious granular mate-
rials  may  also be  present.  Because of its character and  precompression, the
till  likely  has  relatively  high  structural strength.  Due  to  the  impervious
character of  the  surface deposits, the zone: of saturation is expected to be
within a  few feet of  the  ground surface during wet  periods  but significant
quantities  of  free  water will  be  available only where deposits  of sand  and
gravel exist.

   The overlying water-laid deposits will have low structural strength and will be
more pervious;  therefore, they will  probably need to be removed so that the
mountain can be  founded on  the  glacial till. Material so removed  can  be used
for covering the mountain.
   In general,  the  geology of Site  10 is believed to be favorable for solid waste
disposal.  However,  prior  to  final design,  a thorough subsurface investigation
should be made to  determine  in detail the character, depth and areal extent of
bedrock  materials and of the various types of unconsolidated materials over-
lying bedrock, as well as ground water conditions.

     6.   Water  Pollution Potential.   Because the 50 to 100 feet  of relatively
impervious glacial  till overlying bedrock will greatly retard vertical movement of
ground  water, there  appears  little  possibility for leachate or gases  to cause
significant pollution  of  the  bedrock  aquifers.  Although  in  some  areas  the
unconsolidated  material  may  be  excavated  to  a depth of 20  to 30 feet to
remove  unsuitable  foundation material and  to provide cover, it should  be
possible to  leave  a  protective  blanket at least 30 feet thick over the aquifers.
Over most of  the site, the protective  blanket would be much thicker.

     The  impervious character of most of  the unconsolidated deposits  and the
long flow path should prevent  underground flow of leachate into surface waters
in sufficient quantity and strength  to cause pollution.

     7.   Drainage.   Because Site  10 occupies a  drainage divide, surface drain-
age  is  outward  in  all  directions  and no major  water  courses would  be
obstructed.

   On the east and south sides, the ground  surface slopes rapidly upward from
about Elevation  520  along  the rivers to  about Elevation 610 on the  plain.
Numerous small, steep drainage courses, perpendicular to the rivers on  the east
and  south sides of the site,  will provide excellent surface drainage away from
the mountain. Some of these  drainage courses can be enlarged and dammed to
create  small lakes  for  sediment  basins  and, possibly,  leachate  stabilization
lagoons. Ultimately,  these lakes could be used for recreation.

     8.  Accessibility.   Site  10, located approximately 53 highway miles from
the  Chicago  Loop,  is  readily  accessible  by highway, railroad  and  water.
                                    11-11

-------
Interstate 80 which passes one mile north of the site and Interstate 55 which
passes about 2  miles to the east provide  excellent highway access from Cook
County.

   The Chicago,  Rock  Island and Pacific  mainline tracks from  Chicago pass
one-half  mile north of the site,  and the Elgin,  Joliet & Eastern tracks form the
western  boundary  of the site.   The E.J.&E.,  a  beltjine  railroad around  the
periphery of Cook  County,  connects with the major  railroads serving Chicago
and Cook County.

   The Des  Plaines and Illinois Rivers,  which are  the  Illinois Waterway at  this
location, form the southern boundary and  a portion of the eastern boundary of
Site 10 and  offer  potential  for transportation  by   barge,  both from Cook
County and from communities downstream from Site 10.

     9.  Obstruction to Air  Traffic.   The effect  on air traffic of a 1,000 foot
high mountain at Site  10 was discussed with the Chicago Area  Office of the
FAA, and they  conducted a preliminary aeronautical  review. While the adverse
effects of a  1,000 foot  high mountain at Site 10 would be much less severe
than for sites inside Cook  County,  it  will still be an obstruction to some air
traffic.

   The FAA  requests that it be  notified when plans  become more definite so
that  a full aeronautical study can be made and an official airspace determin-
ation  issued. Copies of correspondence with the FAA regarding Site 10 are in
Appendix G.

     10.   Land  Cost.  Information  furnished by MSDGC, based on recent
land  sales  in  the general  area,   indicates  an  average current value of about
$ 1,400 per acre for land in  Site  10.(')  Based on  this  value  and  a 10 per cent
allowance for legal  and other acquisition  expenses, the  7,300 acres of  Site 10
are estimated  to  cost approximately   $11,000,000.  Allowing  an  additional
$3,000,000 for existing dwellings increases  the estimated  site acquisition cost to
$14,000,000.

III.   DESIGN  PROBLEMS
  A landfill constructed to a height of 1,000 feet will pose most of the design
problems  of conventional  sanitary landfills  and, in addition,  a number  of
considerations  unique to a  fill of this unprecedented  height.  The following
major problems were  indentified and solutions for them were formulated.
               •   Subsurface conditions
               •   Structural stability
               •   Decomposition  products
               •   Cover material
               •   Drainage and erosion control
               •   Plant growth

  A.   SUBSURFACE CONDITIONS
  Detailed knowledge of  subsurface conditions on the site will be required  to
make definite  determinations of its suitability to support the mountain, and  to
prevent water  pollution.  Such information will also be necessary for structural
design  of the  fill  and for determining the need  for remedial  work such  as
replacement of gravel deposits with impervious material to prevent migration  of
leachate.
  Since all evaluation of subsurface conditions has been based on generalized
information, it  will be necessary to  make a thorough subsurface investigation  of
the site prior to final  design of the project. Rules of the State Environmental
Protection Agency stipulate that one test hole be drilled for each 5 acres of a
proposed site.

  B.   STRUCTURAL STABILITY
     1.  Foundation.    A fill 1,000 feet in height will impose loads of about
50  tons per square foot on the foundations under the higher portions of the
fill. Preliminary evaluation  of the  geology indicates that this load can pro-
bably be  supported by the.  50 to  100  feet of glacial deposits  which overlie
the bedrock.  These  deposits are  believed to  be predominantly  glacial till,
                                III-l

-------
precompressed to a relatively high strength, Gradual application of the fill over
a period of many years will further consolidate and strengthen this material.

  The lake deposits and  other water worked  deposits which overlie the glacial
till  have much  lower structural  strength  and will have to be excavated  from
under  the  fill so that the mountain can be supported directly on the glacial till.

     2.  Fill.   No existing  sanitary  landfill  has approached  1,000 feet in
height and the structural characteristics are not adequately defined to indicate
whether a  fill of that height would be structurally stable,. Such a fill containing
the proportion of a decomposable matter normally present in  sanitary landfills
would experience settlement of large magnitude over the years. Shear failures
and  massive  slides within  the  fill  are  definite  possibilities.  Settlement  and
structural  instability would make it difficult  or  impractical to maintain  and
operate ski lifts or  other structures on the mountain.
  Elimination  of  organic  matter from  the  mountain  and filling only  with
relatively  stable wastes  such as glass,  metals,  rocks,  ashes,  earth,  etc.,  is
considered the  only  practical  means of providing  reasonable assurance  of
structural stability of the  fill.
  C.   DECOMPOSITION PRODUCTS
     1.  Methane.   A sanitary  landfill in northeastern Illinois containing the
normal proportion  of organic  material  will  decompose  and produce  large
quantities  of  methane  gas.  The  gas  will  move  out of the fill  into  the
atmosphere and adjacent soil. Methane released  to the atmosphere causes no
significant  problem. The points  of gas discharge to  the  atmosphere  can be
controlled  by installing french drains  of rock in  the soil around the perimeter
of the fill and  under the earth cover  and providing  vents from these drains.
Methane discharging from the vents can  be  burned if desired.

  If  methane  moves  through  the  soil into  nearby  enclosed  spaces  under
structures,  it becomes an explosion hazard. Since  there will  be few buildings on
                                 III  -  2

-------
or near the mountain,  the exposure would be  slight  and can be eliminated by
special  construction  to prevent the entry of  gas into  spaces where it  might
accumulate to explosive proportions.

     2.   Carbon Dioxide.   Carbon dioxide, produced by decomposition of
refuse, is  heavier than  air and soluble in water. It tends to move outward  into
the soil around  and under a sanitary landfill  and to be dissolved  by the ground
water. Excess concentrations  of free carbon  dioxide  in ground water make the
water acidic  and cause dissolution of carbonate compounds from soil and rock
formations, which increases hardness of the water. Acidity resulting from  excess
carbon  dioxide  increases the aggressiveness  of a water,  thereby accelerating
corrosion  of such materials as iron, steel, and  concrete. A  number  of cases of
ground  water impairment by  carbon dioxide have been documented by various
investigators.(1)
   However,  studies have shown that an  effective barrier to gas  movement can
be  formed with clay or other fine-textured soils when compacted at optimum
moisture  to  90  per  cent  of maximum   density,   and  that  soil  which  is
maintained   in  a completely saturated  condition has nearly  100  per  cent
efficiency in stopping both the  diffusive and convective flow of gas.(2)

   The  30 to  70 feet of water saturated,  impervious,  silty  clay  till  between
the  bottom  of the  solid waste fill and bedrock should  provide an  effective
barrier  to prevent  the movement  of carbon dioxide into  any useable ground
water under or near the site.  The clay immediately below the fill would be
reworked and compacted to  form a highly impervious membrane.

     3.   Leachate.   Precipitation  and  ground  water  which  enter a landfill
will dissolve  organic matter  and  soluble inorganic  salts from  the refuse  and
flow  out of the fill as a highly polluted  leachate  capable  of contaminating
ground  and  surface water.  Elimination of organics  from  the mountain  would
greatly  reduce organic pollutants  in the  leachate;  but  the leachate could  still
contain inorganics dissolved from  water-soluble wastes.

-------
   A  30 to  70 foot  layer of  relatively impervious glacial till would  be left
between the bottom of the fill and  bedrock to impede the  flow of leachate
into any bedrock aquifer. In some locations  it will probably  be  necessary to
remove pockets  of sand and gravel and replace it  with impervious material.
All wells under the fill will have to  be located and  sealed  to  prevent  leachate
from  entering the  aquifers through  the  wells. Existing wells  on the  site
outside the limits of  the fill would be used for water quality monitoring. In
addition, an underdrain system would be  provided  to  collect leachate before
it  could flow  out of  the  fill.  Leachate so  collected  would  be given a high
degree of biological treatment  in stabilization ditches and in  lagoons created
by damming on-site drainage courses.  Treated leachate would be disposed of
by irrigation  of  grass or crops  on  the solid waste  mountain  site,  and  by
controlled  discharge to the Des Plaines or Illinois  River.  Treatment of leach-
ate is discussed in more detail  in  Section V.
  D.   COVER MATERIAL
  A sanitary  landfill requires  daily cover with  earth or  other  suitable mate-
rial.  In well operated  sanitary landfills, cover material  occupies  from  20 to
30 per cent of the total volume of the fill.

  The total volume of the  proposed mountain  is about  1.7 million  acre-feet,
and the  land  area  covered  by the fill is about 4,500 acres. Assuming that 20
per cent  cover material would be used and  that  this  would be  excavated
from  beneath the fill,  a total of about 340,000 acre-feet of cover would be
required  and the excavation would average  about 75  feet in depth  over the
entire area of  the  mountain. Since the depth of unconsolidated deposits over
bedrock  ranges  from about 50 to 100 feet, there would  not be sufficient
cover material  to allow  30 feet to be  left  in  place to  protect the bedrock
aquifer.

  While  the fine  grained lake deposits and glacial till  would  meet most of
the functional  requirements of sanitary landfill cover, they would be difficult
to spread  and would  become  extremely muddy  and unstable under traffic
during wet weather. Excavation  and spreading  of cover material would  also
be quite difficult  during extended periods of cold weather  when the  ground
surface  might  be  frozen to a depth of several  feet. Under  these conditions,
satisfactory sanitary landfill operation would  be  extremely difficult.
                                   HI-4

-------
   Elimination  of organic materials from the mountain and  filling only with
relatively  stable materials  would reduce  cover material requirements  to a
small  fraction of the  requirement for  a  sanitary landfill,  and at the  same
time  eliminate many of the operational problems associated with earth cover.
The  State "Rules  and  Regulations  for Refuse Disposal Sites and Facilities"
permit  large quantities of noncombustible and  nonpytrescible material  such as
rock, concrete,  broken  pavement, bricks and earth to be placed in a landfill
without daily cover. Such materials are  required to be leveled and compacted
to  prevent unsightly  appearance  and  rodent  harborage, and to  be finally
covered  as required  for  a completed sanitary landfill.

   The  State Environmental  Protection  Agency  advises that  in the future  the
rules  will  require  daily covering for  incinerator  residue,  power  plant  ash,
inorganics  separated  from combined  refuse, and  other waste containing any
organic  matter.  Such wastes  would  be covered in  the mountain. However,
studies  by  Requardt and Harrington indicate  that after about  two years of
stabilization, incinerator residue  can  be used as cover  for a  sanitary  landfill
and  in  several respects  is superior to earth  cover/' * Primary advantages cited
for incinerator residue  over  sandy clay  include:  compactability  over  a broad
range of weather conditions; greater  internal strength after  compaction; free-
dom  from shrinkage upon drying; and  surface rigidity and lack  of muddiness
during wet weather.

   It  is  anticipated  that,  after  a  period   of  aging in  the fill  to  permit
stabilization  of  organic  matter,  incinerator residue and shredded inorganic
materials such  as glass,  cans, ceramics,  etc., could be excavated and  used as
cover for newly deposited wastes.
   The reduced  cover requirement  for  a fill without  organics would reduce
the excavation requirement  to a  depth of 10 to  20  feet  under the entire
mountain.  The   problems of  excavating wet   material  and  dewatering  the
excavation would be  reduced and the  problems of  a  muddy  and unstable
operating surface  for  mobile  equipment would  be virtually eliminated. The
surface   of  the  fill  would  be stable  under all  weather conditions  and  if
properly compacted, the  fill  would be subject only to slight  settlement.

-------
   E.   DRAINAGE AND EROSION CONTROL
   Much  of the drainage  of  surface water  from  the  mountain must  be  by
overland  flow.  Severe  erosion  will  occur on the  long side slopes  unless
provisions  are made to  retard the rate of runoff and prevent  concentrations
of overland flow that  would cause scouring  velocities.

   Establishment of a  dense ground cover of grass and other plant growth  on
the side  slopes  will  be essential  for control of runoff and erosion. Plants will
provide a  physical barrier to  erosion  and will reduce the rate of runoff  by
trapping  water so that it will drain off slowly, giving it  a greater opportunity
to soak into the ground where it will be used to sustain  plant growth.

   To prevent erosive  concentrations of overland  flow, the runoff from roads,
parking areas and similar impervious  surfaces on  the  mountain should  be
spread thinly over  a  large area.  If overland flow  is  greater than can  be
controlled  by plant growth and  uniform distribution, it should  be intercepted
by  terraces and conveyed at low velocity to drains which will carry  it  to the
toe  of the  mountain.  Adequate  drainage  facilities  should be provided  to
convey runoff from there to the Des  Plaines or Illinois  Rivers. If the  runoff
carries an  objectionable  quantity of  sediment,  it should be  passed through
retention  reservoirs where  sediments  would be removed before the water is
discharged  to  the rivers. The retention  reservoirs would be  monitored  for
water  quality. If unacceptable  levels   of  nutrients  are  detected, the  water
would be  recycled onto farm land by irrigation.

   Runoff  from  the  large  working surface on top of the fill during construc-
tion should  not be permitted to flow  down the finished side  slopes.  This
water, which  will  carry an appreciable  sediment load, should  be drained to a
pond at the  base  of the fill. After sedimentation, it  would be  discharged at a
controlled  rate  to the  rivers or, if  necessary,  recycled onto farm land  or
treated and disposed of as outlined  for  leachate.
  F.   PLANT GROWTH
  In  addition  to  its benefits for erosion control, plant growth on the  solid
waste mountain will be vital to development  for park and  recreation use.
  Meager information regarding  plant culture on completed sanitary  landfills
indicates  little  difficulty  with  grass  and shallow rooted  shrubs planted  on
                                   III-6

-------
final  cover at  least two  feet  thick. It is reported, however,  that deeper
rooted shrubs and trees  have  been killed by the heat resulting from decom-
position.
   Elimination  of organic  materials  from the  solid  waste mountain would
greatly reduce  the possibility  of heat damage  to plant life. A final  cover at
least  five  feet  thick  would  also  improve  growth conditions for plants of
medium root depth.
   The high  proportion  of fine grained material in the  lake deposits  and
glacial till  available for  cover  may make these materials too  tight for  opti-
mum plant  growth.  Better growth   characteristics  can  be  gjven  to these
materials by mixing humus with the top 24 inches of the final cover.
   Areas  of heavy  vegetation   around the  base of the  mountain  would be
utilized  for  nutrient  removal from  surface  runoff  and effluent  from  the
leachate  treatment  facilities.  If required,  nutrient-bearing  water  would  be
recycled  onto the land by irrigation where the nutrients would be utilized by
the vegetation.

IV.   TRANSPORTATION
   Transporting  solid wastes from the point of origin to the point of disposal
is a significant  factor in the overall cost of refuse service.  In many situations,
the  cost  of transportation exceeds the cost of disposal. Solid waste hauling
costs are affected  by many factors and under different  conditions may range
as widely  as from $0.02 to  $1.00 P6* ton-mile, based on one-way  distance
and  including the cost of the  return trip.

   Labor  is  a  major  element  of  cpst  in most transportation  methods.  In
systems  involving smaller vehicles,  it may represent  50 to 90 per cent of the
total cost.  The transfer concept  of transportation has  been developed  to
obtain the  cost advantages  of  low manpower  systems. Under this concept,
transfer  stations are provided  close to the area of generation. Refuse collec-
tion  vehicles,  usually  staffed  by  2- to 4-man  crews,  deliver  to  a  transfer
station rather than traveling a long distance  to the disposal site.  The wastes
are  transported from the transfer station  to the remote disposal  facility in
large capacity   vehicles  at  a  low  ratio  of  manpower  per  ton-mile.  Most
transfer  systems utilize tractors and  semitrailers  traveling  over the highways.
Railroads, barges and  possibly  other  transportation systems such as pipelines,
under some conditions,  may also be feasible for transport of solid  wastes.

   Investigations were  made of  the following  methods  for  transport of solid
wastes to the proposed  Ski Mountain site:

              Direct haul in;
                     Compactor type collection trucks
                     Dump  trucks
                     Semitrailers
              Transfer via:
                     Highway vehicles
                     Railroads
                     Barges
                     Pipelines
                     Conveyors
                                 IV - 1

-------
  Bases  for estimating  of the  cost  of  transporting solid  wastes by these
methods are given in Appendix H.
  A.   DIRECT HAUL VIA COLLECTION VEHICLES

     \.   Compactor Trucks.   Hauling  directly to  the  disposal  site  in  the
collection  vehicle  is  the  prevalent  practice  in  Cook  County  and  it will
probably  continue  to be the most economical means for delivering most  of
the refuse generated within a 10 to 15 mile radius of the proposed mountain.
However,  because of  relatively low pay load capacity and  high  capital cost
for compaction  equipment  which  is  not needed for the  hauling function,
collection vehicles generally are not economical for long  distance hauling.

     2.   Self-dumping Trucks  and  Semitrailers.   Open, self-dumping trucks
and tractor-semitrailers are  used extensively for hauling  bulky materials  such
as ashes, demolition debris, rock, and  incinerator residue.


  B.  TRANSFER VIA HIGHWAY VEHICLES
  Where the  disposal facility  is sufficiently remote from the area of gener-
ation, it may be economical to transfer refuse, near its  point of  origin, from
the collection vehicles to considerably larger vehicles for  transportation to the
disposal  site.  The  advantage of  transfer  haul  in high  capacity vehicles is
readily  apparent  from a comparison of the unit cost of hauling in a 20 cubic
yard collection  truck  with a normal  pay load of 5 tons  and in  a 60 cubic
yard vehicle with  a  nominal pay load  of 15 tons. For  a  3-man collection
crew,  a driver only for  the larger vehicle, and a" average speed  of 30 miles
per hour,  the comparative costs are: *1J

              20 cubic yard vehicle             $0.35/ton-mile
              60 cubic yard vehicle             $0.08/ton-mile

  While  the unit haul cost is  substantially  lower in large  capacity  vehicles
used  for  transfer  operations,  the capital and  operating costs  of  transfer

   (1) See Appendix H for cost derivations.
                                 IV-2

-------
 stations are  substantial  and  must  be  charged  to  the transfer  operation.
 Transfer  is  not  economically  justified  unless  the  cost  of direct  haul  in
 collection  vehicles is greater  than the total  cost of transfer, which includes:
     Cost of haul in collection vehicle to  transfer station
     Cost of transfer station
     Cost of haul in transfer vehicle  to disposal site

   To  be of maximum benefit, transfer stations should be centrally located in
 the  area  of  refuse  production  to  minimize  costly transportation  in  low
 capacity collection vehicles. Stations should have good highway access and be
 located  in  industrial  areas which  c»n  accommodate heavy  truck  traffic.
 Figure IV-1 shows potential general  area locations of truck transfer stations
 to  serve Cook  County.  Transfer  stations  should be completely  enclosed,
 architecturally pleasing,  and  designed  to  minimize  nuisance to surrounding
 areas.
   A  transfer system should  have capacity to  handle the  peak  quantity of
 refuse delivered  by  the  collectors it serves.  Experience  suggests  that  daily
 quantities  of  130  per  cent  of  average  daily quantities  can be expected.
 Stations serving primarily residential  collectors  should  be able to  receive most
 of the daily  refuse  in the two  2-hour peak  delivery periods occurring just
 before noon and just before the end of the day shift.

     1.  Unprocessed Refuse  via  Semitrailers.    The  concept of transferring
 residential, commercial and industrial refuse via van-type semitrailers having a
 capacity of about 95  cubic yards and an average pay load of 16 tons  was
 considered.
  Transfer stations would  have  a nominal  capacity of 1,000 tons and  a peak
 capacity of 1,300  tons per day to  accommodate seasonal variation  in  refuse
 production. Nominal annual capacity  of a station  would be 312,000 tons. A
station would  receive most deliveries during the day shift but would be open
24 hours per  day Monday through  Friday and  16 hours on  Saturday.  Loads
would  be  dumped  from  collection  vehicles directly into  transfer  trailers.
Facilities would be provided for loading six semitrailers simultaneously.
                                 IV-3

-------
  Three tractors  would  be provided at  the  station  for  positioning transfer
trailers  and three hydraulic cranes  would level  and pompact the loads  in the
trailers.

     2.   Baled  Refuse  via  Semitrailers.   A  new,  experimental concept  of
receiving  and  baling  refuse at  transfer  stations  and  hauling the  bales  on
flatbed  semitrailers was also considered.

  Transfer stations  would  have  1,000  tons per day nominal capacity with
two  baling presses  operating  two  8-hour shifts, 6 days  per week.  A  third
press would  be  included  for standby.  Refuse in  excess  of average  daily
quantities  would  be handled  by working a third  shift  or by operating the
standby press.
  Most of the refuse would be received  during the day shift but the station
would  be  open  to  receive deliveries 24 hours per  day  on  week days and
16 hours  on  Saturday.  Collection  vehicles would dump into a  storage  pit
from which the material would be conveyed by crane to the presses.

     3.   Shredded and  Separated  Refuse via  Semitrailers.    Preliminary  in-
vestigations were made of the  concept qf shredding and  separating refuse into
organic  materials  and inorganic materials  at transfer stations, and transporting
the separated materials by  van-type semitrailers. Semitrailer volumes  and pay
loads would  be  approximately  95  cubic yards  and  16  tons  for organic
materials, and 60 cubic yard and  20 tons for inorganic materials.

  The  transfer-processing stations would  have  a  nominal  capacity  of  1,000
tons and  a  peak capacity  of  1,300 tons per day to accommodate  seasonal
variations in  refuse production.

  Most of the refuse would be received during the day shift  but all  portions
of the  station would be operated  24 hours on week days  and 16 hours  on
Saturday. Collection  vehicles would dump into a storage  pit  from which the
material would be conveyed by crane to the processing equipment.

   C.  TRANSFER VIA BARGE
   Barging on  the  Illinois  Waterway  offers the possibility of low cost trans-
portation for high density materials. The Waterway provides direct access to the
proposed Ski Mountain  site  from the City  of Chicago,  Evanston and  Niles
Townships,  and the portion of suburban Cook County lying generally between
183rd Street  on  the south and  the  Eisenhower Freeway on the  north.  The
remainder of suburban Cook County is too far from the Waterway to be served
economically by barge.
   Transfer  stations  would  be  required along the  Waterway  where collection
vehicles  could  discharge  materials for loading  onto barges.  They  would in-
corporate off-channel  dock facilities for storing and loading barges.  Figure  IV-2
indicates potential general area locations for barge transfer stations.
   Rock,  ashes, incinerator  residue and  similar inert  materials  could be dis-
charged  directly  from trucks  or other conveyances  into barges.  Processing
operations such as baling, containerization, shredding,  and separation, if used,
could be performed at the transfer stations prior  to  loading.
   Standard  hopper barges on the waterway are 195  feet by 35 feet overall and
have  a  maximum  load capacity of about 1,400  tons. However, maximum  pay
loads are possible  only with  high density materials such as rock and ashes.
Standard  barges can be used on all of the Waterway south of Addison Street.
Smaller  barges having a  load capacity  of 600 tons must  be used  on  the
Waterway north of Addison Street. They can service as far north as Evanston.
   The  maximum  number  of barges  permitted in  tows  on  portions of the
Waterway are as follows:

   The U.S. Corps of Engineers advises that although normal increase  in barge
traffic is  predicted  to reach  the  practical  capacity  of the  Lockport  and
Brandon locks by  1980,  two  factors may make  it possible  to transport a
substantial quantity of solid  wastes  by barge. First, most of  the barges  that
deliver coal  and aggregate to  Cook  County  are empty pn  the downstream
trip  and  might  be used  for hauling solid wastes.  The Corps of Engineers
estimates  that 12  to  13  million  tons  is  the maximum annual quantity of
solid  waste that might be handled  by  existing Waterway facilities.  Second,
construction  of duplicate  locks and  other improvements programed for com-
pletion within the  next 10 years wilj greatly increase  capacity of the Water-
way.
   The Waterway is sufficiently  ice-free for year-around  barge operation  in the
project  area;  however,  during  extremely  cold weather traffic is  sometimes
interrupted by lack of visibility due  to fog rising from the water warmed by
industrial  wastewater.  During January 1970, barge traffic was  halted by  lack
of visibility  for a  continuous period of four days. High  winds  and flood
flows also  cause  minor  interruptions  of barge  traffic.  Because  of these
interruptions,  barging  under  present  conditions is  not  considered sufficiently
reliable  for  transporting  residential,  commercial  and  industrial wastes con-
taining putrescible  materials which require prompt removal for protection of
public health.  Reliability  of  barging  is  considered  adequate  for transporting
relatively  inert solids such as rock, power plant ash, and demolition material.
   The unit cost  of transporting material  by barge is affected  significantly by
density  of the material  since  the  cost  of  owning and moving a  barge  is
essentially  the same regardless of pay  load. Therefore, the  cost of barge
transportation  was  estimated for five categories of  solid wastes representing
the probable  range of  refuse  densities and pay loads, as follows: tunnel rock,
power plant ash, incinerator residue,  baled refuse, and containerized refuse.

     1.   Rock and  Ashes.   Rock  and power plant ashes are  dense enough
to load a standard hopper barge to its maximum  capacity  of 1,400  tons.
Because these materials.are relatively  inert, they could be transported in open
                                   IV-6

 barges  without  causing pollution,  although  covering  will be  required  to
 prevent  blowing of ashes. A rigid hauling schedule would not be required for
 sanitary  reasons,  and  interruptions of barge traffic would  not  be serious
 enough  to  preclude this mode of transportation for inert  wastes. A loading
 station for rock  or ash would consist of barge  docking facilities, provisions
 for  discharging the material from trucks or other conveyances  directly into
 the  barge,  and means for trimming the load on the barge.

   At  the  disposal  site, rock  and  ash would  be unloaded from barges by
 crane  and hauled to the final disposal area in off-highway mining trucks  of
 approximately 100 tons pay load capacity,

     2.  Incinerator  Residue.    By  use  of sideboards,  barges  can be loaded
 with 1,000 tons of incinerator residue,  This compares  with a 1,400 ton pay
 load for rock. However, since  some residue contains putrescible matter which
 attracts  flies and  emits  odors, slow  barge transportation would not be accept-
 able for  residue unless it were  thoroughly combusted-
     3.  Baled  Refuse.    The general run of residential refuse might be baled
 to  an average  density of about 60  pounds per cubic  foot, or 1,600 pounds
 per  cubic  yard, and  a pay load of  1,200 tons of bales achieved  for standard
 hopper barges.  Baled refuse could be transported without significant pollution
 hazard  although covering would, be  required to  prevent blowing of paper or
 other materials raveled from exposed bale surfaces.

   Refuse would  be  baled at transfer  stations prior to loading onto barges.
 Transfer stations  would  include barge docks  and facilities for loading  bales.
 At   the  disposal  site, bales would  be unloaded  by  crane  onto  large  off-
 highway trucks for  hauling  to • the final  disposal  area. Modified  fcrk lift or
 log stacking type equipment might  be used to remove bales  from trucks  and
 place them  in the fill.
     4.   Containerized Refuse.   Consideration was given to  loading residen-
 tial,  commercial and  industrial refuse  at  transfer stations  into fully  enclosed
steel containers by  hydraulic ram compactors to  an average  density of 650
pounds  per cubic  yard and transporting by barge to  the proposed  solid waste
mountain site.  Containerization would  increase refuse density and provide
sanitary and litter-free transportation, unloading and conveyance from barges to
                                   IV-7

-------
the  final disposal  area.  Containerization also might  overcome  some  of the
objection of delays in barging this type of refuse.
   Pay load estimates  were based on containers measuring  about 8' x 9' x 23'
outside and having a capacity of about 43  cubic yards, 42 containers on a
standard barge, a gross pay load of 800 tons, and an average net refuse load of
600 tons per barge.
   Containers  would  be  loaded and unloaded from  barges by crane.  Large
off-highway trucks would be used to  haul containers from the  barges to the
final disposal area.
   D.  TRANSFER VIA RAILROAD
   A  number  of railroads,  including some  operating  in  the  Chicago area,
have  offered  solid waste  disposal service  to  large municipalities and metro-
politan areas.  In most instances, the railroads, or combinations of a railroad and
a  disposal contractor,  offer a complete package  including transfer stations
located throughout the refuse generation area, rail  transporation, and disposal
of solid wastes by sanitary landfill.
   An  indication  of the general magnitude of cost for  such  service is provided
by  a proposal submitted  to the City of Milwaukee,  Wisconsin, in  1970, of
$6.20  per ton for  the  general  run of  residential  refuse, tree refuse,  and
demolition debris for a minimum quantity of approximately  1,000,000 tons per
year.  The  bidder  offered to provide  three transfer stations for receiving solid
waste, transport  wastes by rail to a  disposal  site more than 200 miles from
Milwaukee, and dispose of them by sanitary landfill. No shredding, separation,
or  other  processing  of wastes  was  proposed. Assuming  a landfill cost of
approximately $1.20 per  ton indicates a  cost of about  $5.00 per ton for
receiving and  transporting; solid wastes from Milwaukee, with all transportation
provided by a single railroad.
  Different conditions for transporting Cook County solid wastes by rail  would
probably result in different unit costs. For example, since no single railroad has
trackage  located to serve all of Cook County, a number of railroads would have
to  be involved which  would  tend to  increase costs.  Conversely, the  larger
quantity  of wastes and much shorter haul  distance would  tend to lower the
unit cost.

-------
   Three railroad companies operating in the Chicago area made a joint study of
 the feasibility  and cost  of transporting solid wastes from Cook County  to  the
 Ski Mountain.  The reports of the railroad companies are in Appendix I.
   Using  the  data  and  estimated rail transportation costs  furnished  by  the
 railroads  and the costs for transfer and processing stations developed herein for
 other  transportation methods, estimates  were made  of the cost for receiving,
 processing,  loading, transporting by  rail, unloading, and  placement in the  Ski
 Mountain  of  various  type of solid  wastes. These estimates  are  presented in
 Appendix H.
   Generalized  locations  for potential solid waste transfer and processing station
 for rail transportation are indicated on Figure IV-3.
   E,  PIPELINE SLURRY TRANSPQRT
   A  preliminary evaluation  was made of transporting solid wastes in a slurry
through pipelines to  the proposed Ski Mountain. Because this method has been
only  meagerly researched for transporting heterogeneous solid wastes and there
have  been no field scale installations for this purpose,  the evaluation  is based
on numerous  assumptions.  An  estimate was made to determine  the  general
magnitude of cost to  indicate whether more detailed  investigation  of this
transportation method was justified.

   The  analysis was  based  on  a  hypothetical system  designed to transport
15,000 tons  of solids per day through one pipeline over a distance of 53 miles,
and  an annual delivery of 4.2 million tons.  The system would operate  contin-
uously  24 hours per day  and 7 days per week to minimize the possibility of
plugging in the pipeline.

     1.  Description  of System.   The  pipeline transport system was  consid-
ered in three  sections: receiving  and processing; pipeline and booster pumping;
and separation of solids and wastewater treatment.

       a.  Receiving  and  processing.  Ten receiving and processing stations,
each  designed to handle 1,500  tons of  solid wastes per 24 hours, would  be
strategically  located  throughout  Cook  County.  Residential,  commercial and
industrial refuse would  be  delivered to the  stations,  principally  during the
                                   IV-9

-------
day shift,  by  refuse  collection  forces. Enclosed  refuse storage would  be
provided  in  the stations  to  permit 24 hour per day operation of processing
and transport systems.
   Processing would be conducted in buildings and would include the follow-
ing major operations:
     Shredding to facilitate subsequent processing
     Magnetic separation  of ferrous metal for sale or disposal by other
     methods, supplemented by manual separation if necessary
     Screening and air  separation to remove glass, rock, nonfejrous
     metal and similar  high  density  materials  for  transportation by
     other methods
     Pulping the remaining basically organic wastes and mixing  with
     water to form a slurry
     Pumping the slurry into the pipeline

   Because processes  for  separation  of solid  wastes are  not  well developed,
alternative or additional processes  may be found  necessary.

       b.  Pipeline and booster  pumping.   Analysis of pipeline and  pumping
facilities for  delivering  solid  waste slurry to the disposal site was based on a
single  42 inch pipeline  53 miles  long.  Booster  pumping  stations would  be
necessary at  about 2 mile intervals. The pipeline would  convey 15,000  tons
of  solids  per day as a 6  per cent slurry, at a velocity  of 10 feet per second
and a  pumped volume  of  60  million gallons  per  day. Conveyance water
would  be  taken from  the Illinois Waterway near  the  receiving stations and
returned to the Waterway near the disposal site.

       c.  Separation of  solids and wastewater  treatment.   At the disposal
site, it would be  necessary  to separate the solids  from the liquid  and treat
the  polluted  carrier  water to a  quality  acceptable for  discharge  into  the
Waterway. The  portion of the Waterway adjacent to the  site is designated  an
Industrial Water Supply  Sector  by  the Illinois  Sanitary  Water Board. Water
                                 IV- 10

-------
 quality standards for the rivers are set forth in Rules and Regulations SWB-8
 promulgated by  the  Board.

   Analysis of separation and  wastewater treatment was premised on use of
 the following facilities:

        Grit  tanks  to remove  heavy solids and  small particles of dense
        materials such as ashes, sand, glass, gravel,  tramp metal, ceram-
        ics, and  synthetics  which  may  settle  to  the bottom  under
        conditions of relative quiescence

        Pulp  dewatering equipment similar to the  helical screw presses
        or disc  presses  used by  the pulp  and   paper industry,  to
        dewater the  bulk of the predominantly organic wastes in the
        slurry

        Sedimentation tanks  to remove  additional solids and  reduce
        the solids  contents  of the  effluent discharged  to subsequent
        wastewater  treatment units

        Thickening  tanks  to concentrate  solids removed in the  sedi-
        mentation  tanks  prior  to  recycling these  solids through the
        pulp  dewatering equipment

        Activated sludge  units  consisting  of  aeration  tanks  and  final
        clarifiers  to biologically  oxidized  organic pollution in the car-
        rier water,  with any settled solids being recycled through the
        thickening tanks and the pulp dewatering equipment

        Chlorination for control of biological pollution
   2.   Evaluation.   Pipeline  slurry  transport  would  require  processes  and
equipment  not yet tested and  proven  satisfactory  on an  operational scale.
Extensive full  scale testing and  equipment  modification, or  development  of
new equipment,  would  be required  before a pipeline slurry transport system
could  be designed  and constructed  with reasonable assurance of successful
operation.

   Plugging,  breakage,  or other failure of the slurry pipeline  would halt refuse
disposal  service for the entire community served by  it.  A standby pipeline
                                 IV- 11

-------
might be required to insure reliability of service. The cost of a standby pipeline
was not included in the cost estimate.
   Because the system has not been proven for handling solid wastes, and  will
increase  the  problems of water pollution control, pipeline  slurry transport  is
not considered a satisfactory method for transporting Cook County solid wastes
to the proposed Ski Mountain site.
  F.   OTHER TRANSPORT SYSTEMS
  Two transport  systems  were  considered  and  rejepted  on  the  basis  of
preliminary evaluation.
  Pneumatic conveyance in pipelines was considered impractical because power
requirements would  be excessive and present equipment limits conveying runs
to a few thousand feet between compressor stations. A pneumatic pipeline 53
miles  long  would  require  a multitude  of compressor  stations  operating in
series.  Each  station  would  require  cyclones  to  separate solids  from  the
conveying air and  air  locks  to reintroduce  solids  into  the high pressure  air
stream on  the  discharge side of the station.  In addition,  each station would
require high  efficiency dust collectors  for  dust  not captured  by the  cyclone
separators,  which  are inefficient  on particle  sizes  smaller than  10  microns.
High  moisture  content of the  refuse might  prevent use of economical cloth
bag  collectors  because the  moisture  would  blind the pores of the cloth.
Electrostatic  precipitators  would  be uneconomical, and  wet collectors would
form  sludge which would lead to  additional disposal problems.
  Belt conveyors  were considered  impractical because  of the difficulty  and
cost of  acquiring right-of-way across  densely built-up  urban areas;  cost  of
constructing  and operating the multiple-belt  conveyors  required to transport
the large  quantity  of low  density  material;  litter  and  dust problems, partic-
ularly  at  belt  transfer points;  odor problems;  and fire and  dust  explosion
hazards.  A  conveyor  system  requiring completely  new  right-of-way  and
complete  construction of  all  facilities  would  face  a significant cost  dis-
advantage in competing with  rail or  barge  transportation systems operating
                                   IV- 12

-------
 over  existing tracks  or waterways, the  cost  of which  would  be shared oy
 other traffic.
   G.  COMPARISON OF TRANSPORTATION SYSTEMS
   Table IV-1 shows  a comparison of the  average estimated costs for various
methods  of processing  and  transporting Cook  County  solid  waste to the
proposed Ski Mountain. These costs  were calculated  from the cost curves and
tables presented in  Appendix H  and are  averages for all  of Cook County.
Unless  otherwise  indicated, the  estimates  include  all costs from  the time
materials are received at  a  transfer station  until  discharged  into the Ski
Mountain.  Costs of spreading,  compacting,  tilling and other subsequent opera-
tions are  not  included.  Table IV-J  shows the  total estimated capital and
operating cost per ton of  solid waste  transported, and the  estimated capital
investment  required  per  1,000 tons per  day of  transportation  capacity for
average  daily   conditions,  including the  capability  to  handle  peak  daily
quantities 30 per cent greater than average.
   Barge  transportation is indicated  to  be the lowest cost method for deliver-
ing high density materials such as deep  tunnel  rock,  incinerator residue, and
power plant ash to  the  Ski Mountain site. The waterways  on which  barges
must travel are  also  favorably located  with respect  to the  origination  points
of  these  materials.  Barge  transportation should  be  used  to the  maximum
practical extent  for delivering  dense  inorganic materials to the Ski Mountain.
As discussed  previously,  due to  traffic  limitations  of the Illinois Waterway,
maximum  annual delivery  of  solid  waste  would  be  restricted  to  about  13
million  tons until planned  improvements to the Waterway are completed by
about  1980. This rate of annual  delivery could be achieved  only by utilizing
some of the existing coal and  aggregate  barges which are now empty on the
down-river trip.
   Prolonged interruption of  barge  traffic  caused  by poor visibility in ex-
tremely  cold  weather makes  barge transportation unsuitable for moving the
general run  of residential, commercial, and industrial  refuse even if the wastes

are  containerized or  in  a form which precludes development of unsanitary
conditions during transit. Portection of public health  requires that the trans-
portation system  be highly reliable  so that wastes can be removed promptly
and  prolonged  accumulations of wastes in urban areas are avoided. Lack of
flexibility  in  locating barge transfer  stations and the  resultant long  haul
distance required for collection vehicles  are  also  decided  disadvantages of
barge transportation for these materials.
  Transfer via highway semitrailers  and transfer via rail cars are both  consid-
ered  suitable methods  for delivering  residential,  commercial, and industrial
refuse to the Ski Mountain.  Because transportation via rail is indicated to be
lower  in cost,  evaluation of  the  Ski  Mountain concept  was  premised  on
transferring  residential,   commercial,  and  industrial refuse and  combustible
demolition debris  from Cook County via railroad  cars.
  Although  rail  transport  would be less  flexible than highway transport, it
would have  the advantage of a much  lower  volume of refuse vehicle  traffic
on the highways  leading to  the Ski  Mountain site. Less littering and other
inconvenience along highways and roads leading to the site would also result
from rail transport.

 V.  THE  SKI   MOUNTAIN  PLAN
   The  solid wastes of Cook County  would be separated  into two  categories:
 inorganic materials  and organic  materials. The inorganic  fraction would con-
 sist  principally  of such  materials  as  metals,  glass,  ashes, ceramics, soil,
 concrete, masonry,  rubber  and heavy  plastics.  The organics would  consist
 principally of paper, cardboard,  cloth, wood, grass, brush, leaves, food  wastes
 and  light  plastics.  Complete  separation of  organic  and  inorganic materials
 would  be  neither  practical  nor  necessary.  The separated materials would  be
 salvaged to the  maximum  practical extent.  The remainder  of the inorganic
 materials would  be  used to construct a  1,000-foot high  mountain for skiing
 and  other  outdoor recreation. Unsalvaged organic material would be returned
 to the land.
   The  system to  accomplish these  objectives  would  require  the  following
 major operations:
        Receiving, processing, and transportation of materials
       Construction of the  Ski Mountain
       Placing organic materials on the land
   A  public  agency  would be  established  to  manage  all  operations. The
 agency  would  own  all land, equipment,  and other facilities  required for the
 entire  system  except  that  tugs and existing  railroad  trackage  would  be
 provided and operated, under contract, by private contractors.
   Analysis of the system was premised on handling the total projected 1975
 quantities of  Cook  County solid waste,  assuming that  none of these  wastes

  A.  RECEIVING, PROCESSING AND  TRANSPORTATION
  To minimize  transportation costs,  most  of the  solid  waste from Cook
County  would be delivered  to transfer stations strategically  located through-
out  the area  of production.  Potential  transportation systems  are described

 and generalized  locations for  transfer stations for highway,  rail,  and barge
 transportation  are given in Section IV. Methods for estimating the cost of
 transport by these systems are  presented in Appendix H.
   Table V-l  shows the projected annual quantities of organic  and inorganic
 materials from Cook  County  and  the volume that  the inorganic materials
 would  occupy in  the Ski Mountain  excluding  any cover material obtained
 outside  the fill  space. Excavation  for cover material  within the  fill space
 results  in  an equal volume of fill  space which offsets the space  that cover
 material occupies  in  the fill.  Volume  requirements  were based  on  average
 densities in the mountain, as follows:

     1.   Barge Transportation.  High density  materials such as Deep  Tunnel
rock,  power  plant ash,  and  noncombustible  demolition  debris  would  be
delivered  to  barge  loading  stations  on  the  Waterway.  These are  primarily
inorganic  materials  and would require no  separation  or  processing prior to
being placed in the  mountain.
   Barge loading stations would be located  as close as  possible  to the sources
of  solid wastes  to  minimize  the  cost of delivering material  to the  barges.
Generalized locations  for  potential  barge  loading  stations are  shown  on
Figure IV-2. Barge loading stations would not be provided for the general run
of residential,  commercial and industrial refuse.
   The estimated  capital investment,  annual  cost,  and  unit cost  for  trans-
porting projected 1975  quantities  of power plant ashes, screenings, sweepings
and Deep Tunnel rock to the Ski Mountain are as follows:

     2.  Railroad  Transportation.   Residential,  commercial,  and  industrial
refuse  and  combustible  demolition  debris  would  be  received  at  transfer
stations designed to  separate  organic materials from inorganic materials  and
to load each separately into rail cars.  The relatively stable  inorganic  material
would  be  transported  to  and  placed in  the  solid  waste mountain.  Organic
materials would be transported to and  deposited  on land into which it would
be  tilled.  Initially,  a  portion  of  the Ski  Mountain site  could  be  used to
receive organics; however  additional land  would  be required for this purpose,
as discussed  later in this section.

        a.  Transfer.    Twelve  transfer stations,  with capacities ranging from
1,000 to  2,500 tons  of refuse per average day, would  be provided  initially
for the 6,266,000  tons of  residential, commercial, and  industrial refuse  and
combustible  demolition debris  projected  for  1975. Generalised locations for
rail transfer  stations are indicated on  Figure IV-3.

        b.  Separation.   Separation of heterogenous solid waste into organic
and  inorganic fractions will be necessary  to reclaim and reuse materials  and
to obtain  relatively  stable materials for constructing the Ski Mountain. Com-
plete  separation  will  be  neither  practical  nor  necessary;  however,  the  fill
material must be sufficiently free of  organic material to  be  structurally stable
in deep fills.  It  will  be necessary to  determine experimentally the  required
degree  of  separation to yield stable fill material.
   Systems for  separation  of solid  waste into organics  and inorganic fractions
on an operating scale have  not been  developed.  The general state of the art

of solid  waste  separation  was  reviewed by  Drobny, Hull  and Testin, who
reported :(1)
       As of 1968,  the  most  widely employed means for  separating
       solid  waste is handpicking  and  sorting from conveyors.	
       very  few of the  more sophisticated separation techniques have
       been applied  to  solid waste processing and the historical ex-
       perience  of these applications  is  extremely limited.  Generally
       speaking, there is almost a universal  lack of data related  to
       mechanical  separation  of solid  waste.	several potentially
       promising separation techniques  are available;  but  additional
       experimental work is required  to  establish performance criteria
       and cost relationships suitable for  design purposes.

   To  achieve  the required  degree of  separation,  it  will  be  necessary  to
develop  an  operable  system.  Preliminary cost estimates for this study  were
based  on  the  assumption  that  residential,  commercial  and  industrial refuse
and combustible demolition debris  would be  shredded and then separated  by
a  combination  of methods, including air classification,  magnetic separation,
and screening. The cost estimates are necessarily approximations.
   To  minimize  materials  handling, which  according to Drobny is a  major
cost factor in solid waste processing,(2)  the study  was premised  on  shredding
and separating at  the transfer  stations where  it  would  be  necessary that the
materials  be  rehandled anyway  to  transfer them from  collection vehicles  to
rail  cars.   Preprocessing  at  the  transfer  stations would  facilitate subsequent
handling  and  transportation and would  make  it  possible  to  haul material
directly to the final  placement  areas,  obviating the rehandling that  would  be
required  if unprocessed  refuse  were delivered to the Ski  Mountain site and
separated   there.  It is possible  that detailed  planning and design of  the Ski
Mountain  system will show that a  central shredding and separation  station at
the  Ski  Mountain  site would  be  more  feasible.  However,  considering  the

present undeveloped state  of solid waste salvage markets and of the technol-
ogy  of  solid  waste separation,  it would  not be  possible  at this time  to
determine  definitely the most feasible location for  these processing facilities.
   Shredding will  be necessary to tear open packages and to reduce material
to  sizes  which  can  be  processed  by  mechanical  separation  devices.  Size
reduction  will produce  other benefits,  including higher material  density  in
transport systems  and  in the  solid  waste  mountain,  reduced blowing and
littering  of materials, reduced odor and attraction for vermin, and more rapid
biological stabilization of organics placed on  the land.
   Shredding equipment has  been successfully demonstrated for size reduction
of refuse in a  number of compost  plants, and the City of Madison, Wisconsin
has conducted extensive investigations on shredding of solid waste/!) Num-
erous   heavy-duty  shredders are  also  being used to reduce auto bodies  to
hand-size scrap metal.
   Although there are several types of size reduction equipment, hammermills
are used in about 90  per  cent  of existing  solid  waste shredding installa-
tions/2^ The principal reason for the predominant use of hammermills is the
heavier  construction  of  this  type  machine which gives it the  ability  to
process  the wide  range  of materials   found  in  solid   wastes.  Knife  type
shredders,  widely  used in industrial  applications,  are  generally  not suitable
because  the knives  are  rapidly  dulled  and  damaged by objects in  mixed
refuse.
   Separation  techniques depend  upon detecting and acting  upon differences
in certain   characteristics  of the  materials  being  separated,  such as particle
size,  friability, surface  characteristics,   specific  gravity,  and  magnetic  pro-
perties.  Because,  in most instances,  the materials  to be separated  are not
sufficiently  unique  to  permit complete  separation  by any one technique, a
number  of  stages  using  different methods will  probably   be  required  to
achieve an acceptable degree  of separation.

   Magnetic  separation  of ferrous  metals from incinerator  residue, shredded
auto  scrap, shredded  refuse, and compost has been accomplished successfully
in a number of solid  waste processing plants.(1) Although magnetic properties
are sufficiently unique to  permit  a  relatively  high  degree of  separation  of
ferrous metals,  the metal scrap may  contain  enough entrapped  organic  fibers
and other foreign material to necessitate additional separation.
   Air classification separates materials  according to  density, size and  aero-
dynamic  properties.  Experimental  work has  demonstrated  that  high  density
materials  such  as glass, dirt, metallics, and  rocks  can  be readily  separated
from  dry shredded municipal refuse by  air classification.(2)

   Screening separates materials on the basis  of  particle size and  has  been
used  in  the processing of  shredded solid waste and  compost at composting
plants. Screening  may be used  for separating oversize objects for further size
reduction; however, one of  its  principal applications would appear  to be for
removing  brittle   materials  such  as   glass,   ceramics,  brick,  masonry,  and
thermosetting plastics which are shattered to  small particles by impact during
size  reduction.  In experimental testing, the  U.S. Bureau  of Mines screened
shredded  municipal refuse through a 4-mesh screen and captured 87 per cent
of the dirt and glass, contaminated by less than  4 per  cent  of the combus-
tible  material in the  original sample.(3)  The tests  showed that preliminary air
classification  prior to  screening facilitated screening  by  reducing moisture
content  of the refuse. As part of the U.S.  Bureau of Mines  experiments,
separation of  shredded  minus  6-inch  municipal  refuse by  air  classification
followed  by magnetic separation of the heavy product and screening of  other
products on a 4-mesh screen obtained the following results :(3)
       The simple processing steps outlined were effective in recover-
       ing  92 per  cent of  the metal  in  a  clean product. The  plus

       4-mesh elutriated product  represented 97 per cent recovery of
       the  combustibles and  contained only  3 per  cent  of noncom-
       bustible impurities.  This product  should  be  eminently satis-
       factory as a  fuel.  The  minus 4-mesh elutriated product  repre-
       senting only  18.7 per  cent  of the  weight of  the raw  refuse
       could  be discarded to landfill with only a 3 per  cent loss of
       the combustibles.

   Although experimental  results indicate that a high  degree  of separation of
solid  wastes can  be achieved, full-scale  pilot systems,  processing the full range
of  residential, commercial,  and industrial refuse and  combustible  demolition
debris,  will  probably   be  required  to develop  necessary  design and cost
parameters  for constructing feasible separation  facilities for the  Ski Mountain
project.
   Preliminary cost estimates for receiving, shredding, separating as discussed,  and
transporting  separated   materials via railroad  cars  are  given  in Appendix H.
The estimated capital investment, annual cost and unit cost  for  the projected
1975  quantity of residential,   commercial,  and  industrial refuse  and com-
bustible  demolition debris are summarized  below:

  B.   SKI MOUNTAIN CONSTRUCTION

     1.   Site  Acquisition and Development

       a. Site acquisition.   The land  comprising the  Ski  Mountain site  is
privately  owned  and would have to  be  acquired by purchase or  condem-
nation.  As  discussed  in  Section II,  acquisition  of  the  7,300 acre  site  is
estimated to cost approximately $14,000,000.
                                    V-8

-------
        b.  Subsurface  investigation.   Prior  to actual  acquisition of land,  suf-
ficient  subsurface investigation should  be  done to  verify  the general  suita-
bility of the underlying geologic  formations for supporting  the mountain  and
preventing  ground  water  pollution. Much  of  this  preliminary investigation
could be done on public road rights-of-way, but it may be necessary to make
some borings on private land.
   If  preliminary  investigations  confirm  the  general suitability,  a compre-
hensive  investigation should be made to locate, define, and map subsurface
deposits which  will influence design and construction of the mountain.  These
might  include:  low strength  surface  deposits  requiring removal so  that  the
mountain could bear directly  on high strength materials; deep deposits of  low
strength material  which  would  influence design  for structural stability; or
highly  pervious  deposits   requiring  removal  or blanketing  with  impervious
material to prevent ground water  pollution.
   Based on the  State  EPA requirement  of  one test hole  for each 5  acres,
subsurface investigation of the 7,300  acre  site is  estimated to cost approxi-
mately  $1,325,000.

       c.  Utility relocation.   A  number of utility easements cross the  site
and  will conflict  with Ski  Mountain.  Estimated  relocation costs,  based on
on-site rights-of-way provided at no cost to the companies,  were provided by
the utility companies, as follows:

-------
  Copies of  estimates  furnished  by  the utility companies are included  in
Appendix G.

       d.  Site  development.   Considerable work  and  expense will  be  re-
quired  to prepare  the  site  for  construction  of  Ski  Mountain.  The  initial
construction of  the mountain  would  occupy  an  area  of about one square
mile at the south end of the site.
  Stripping of  unsuitable material and  cover  material  from the fill area,  as
discussed on  the following  page,  would be performed  as a part of the  fill
operation and its cost was included as  an operating expense.
  Barge  unloading facilities  would be  provided along the north bank of the
Illinois  Waterway  close  to  the   initial  mountain  construction  where  they
would be  screened  by  the  Kankakee  Bluffs. The  costs of these facilities are
included  in  the  estimated   cost  of  barge  transport   systems  presented  in
Appendix H.
  Railroad  spur tracks  would  be extended  from  the  existing  tracks on the
west  side  of the  site to unloading facilities  in the southwest corner.  The
unloading  facilities  would  be close to  the  area of initial  construction  and
would be  screened  by  the  bluffs. Costs of spur tracks and unloading yards
are  included as  part  of the cost of  the rail  transport system presented  in
Appendix H.
  Approximately  5  miles  of surfaced  all-weather road  would be  provided
from  the 1-80 exit north of the site  to the  initial fill  area.  Relocation  of
U.S. Highway 6 would be necessary eventually, but the highway  could remain
in service during construction of the first phase of the mountain which may-
require  30 years or longer.  Therefore, the cost  of highway relocation was not
included in the  initial site development  cost.
  Some  5  miles of security fencing  would be provided around the  initial
mountain construction area.
  Structures would be provided for a field  office,  employee facilities, scales,
and landfill equipment servicing, complete with parking  lots, area lighting and
                                   V- 10

-------
landscaping.  These  facilities together with fencing and  the access  road from
1-80 were  estimated to cost $1,650,000.

     2.  Construction
        a.  Rate  of filling.   If constructed with  average 4:1  side slopes (4
horizontal to 1 vertical), the initial fill area of approximately one square mile
at  the south end of the  site would  reach  a height  of about  660 feet and
contain about  140,000 acre-feet of fill.
   Table V-l  shows  that the projected cumulative volume of inorganic solid
fill material  from Cook  County  over the  1971-1995 period  is approximately
116,000 acre-feet. Assuming that all  of it  is placed in the fill, the fill  would
rise at the rate  of  about  15  feet per year in the early  years and completion
of the initial part of the  mountain would require 35  to 40 years.  The initial
fill would  be about 7 per  cent of the total volume of the Ski Mountain.

        b.  Stripping.   Prior to placing fill, the area to be covered would be
excavated  to an average  depth  of at least  10  feet,  and to greater  depths
where necessary to remove unsuitable  foundation material.  Because  the top
of the zone of saturation  in  this part of  Illinois  is generally within 5  to 10
feet  of the  ground  surface,  according  to  Hughes(' *  dewatering may  be
required to provide a dry  work  area.  Excavated material would be placed in
a  graded  berm  around the perimeter  of the  initial fill site  and subsequently
used  to cover  the final outside surfaces of the initial mountain  to  an average
thickness of about  10 feet. Berms  of cover material would be constructed to
a height of 50 feet  with 4:1 side slopes which would be  planted to grass and
mowed.  Berms,  which  would  be sloped  to drain away  from  the fill  area,
would keep  outside drainage from  entering the fill site and would  screen the
fill operation from view for several years.
       c.  Filling.   The  Ski   Mountain   fill  would   rest  directly on  high
strength  glacial   till  and   would   be  constructed  with  relatively  stable,

-------
predominantly inorganic  materials such as rock, glass, ceramics, metals, ashes,
brick,  concrete, and earth.
   Preliminary design was based on average side slopes in the range of 3:1  to
4:1  to permit  mowing and  maintenance. Using data obtained  in  the  com-
prehensive subsurface  investigation,  determinations should be  made of  the
structural properties of the underlying geologic  formations and the fill mate-
rials to  establish  design  parameters and  construction procedures required  to
assure  structural stability of the fill.

   The bottom  layer of fill would be  rock and other  highly pervious material
through  which  water could flow laterally to a collection  system at the edge
of  the fill. This  free  exit for liquids  would minimize  buildup of  the water
table within  the fill and reduce  the possibility of springs on  the sides of  the
mountain.  The  resultant  reduction of  hydrostatic pressure at the base of  the
fill would  also  tend to reduce  percolation through the underlying formations.
The drainage layer should be the maximum thickness  obtainable with  the
available pervious  fill material.

   Solid wastes  would  be dumped from trucks in the fill area, spread in thin
layers  by  crawler  tractors, and compacted.  Ashes,  inorganics separated  from
combined  refuse,  incinerator residue,  and other wastes  requiring daily cover
would  be placed in compacted cells 8 to 10 feet in depth and covered  daily
with earth or other suitable  material  in  accordance  with approved sanitary
landfill practice. Rock,  brick, concrete, and similar stable fill materials free ot
decomposable or  combustible matter  would  be leveled  and  compacted, but
would  not require daily cover.
   Outer edges  of  the  fill would be  carried at a  higher  elevation than  the
interior to prevent  surface runoff of  the  fill  area from  flowing  down  and
eroding  the  side  slopes.  Interior surface drainage would be  diverted into
sedimentation ponds at the base of the  fill.  The raised  edge would assist in
screening the fill  operation from public view. Access  to  the working area  for
hauling vehicles would  be  provided by roads constructed  on  the side of  the
fill.
                                   V- 12

-------
       d.  Covering.    During the early years  of the  operation, earth exca-
 vated  from  the  fill  area  would  be used  for covering wastes requiring daily
 cover. After about  two  years  of aging  in  the fill,  any small amount  of
 organic matter contained  in  the  inorganic material  separated from  combined
 refuse would become  stabilized  by natural biological  action. After  a  supply
 of  aged  inorganic material becomes available,  this material would be used for
 daily cover.  As discussed  in  Section HI under "Cover Material", aged inciner-
 ator residue  and inorganic material are expected to  be superior to  earth for
 daily cover and  use  of these materials for cover would overcome operational
 difficulties that  otherwise  would  make construction of a solid waste  moun-
 tain extremely difficult.
  To provide favorable conditions  for the growth of a wide  variety of trees,
 shrubbery  and other vegetation the outside slope of the mountain  would  be
 covered  to  a  depth  of approximately  10 feet with earth  excavated from
 under  the fill area.  Since the  slope  distance on a  4:1  slope  is only 3 per
 cent  greater  than  its  horizontal  projection,  10 feet of side  cover  would
 require  only about  10.3 feet average depth of  excavation over the  fill area.
 Humus  would  be mixed with the  top 24 inches of the side slope  cover  to
 provide better growth  conditions  for  plants.  A  dense ground cover of grass
 and other  plants would be established on the covered  side slopes for control
 of runoff and erosion.

       e.   Equipment.   During the initial years, the fill would be  operated
 with  the  type   of  earthmoving  equipment used  on conventional  sanitary
 landfills.  It is estimated that one  385  horsepower crawler tractor and 4 twin
 engine wheel scrapers of 32 cubic yard struck capacity would be required  to
strip and stockpile unsuitable foundation material from the fill area,  haul and
spread cover  material, and construct sedimentation and  stabilization ponds for
runoff and leachate.
  It is estimated that 17 crawler  tractors  of 385 horsepower rating would be
required  to spread and compact  the  projected   1975  quantity  of rock  and
other inorganic material  shown in  Table V-l.
                                   V-13

-------
   Miscellaneous equipment  would  include  motor  graders, water  trucks, fuel
and servicing truck, pickup trucks, and automobiles.
   The average economic life of equipment was estimated  as follows:  scrapers,
15,000 hours;  tractors,  12,000 hours; water trucks, motor graders and servic-
ing trucks, 10  years; and automobiles and pickup trucks, 5 years.

       f.  Leachate control.   Provisions would be made for collecting and
treating  leachate  from  the mountain  to minimize any  possibility of  water
pollution.
   The quality  of leachate  is expected  to be quite varied. Because it may  be
impossible to  eliminate completely all organic  matter from the  fill, leachate
may  contain  dissolved  and  suspended  organic matter  that  would  exert  a
biochemical oxygen demand  (BOD). However,  due to the low proportion  of
organic  material  in the  fill,  the BOD is  expected to  be relatively  low.
Chemical  contaminants  dissolved from ash and inorganic materials may also
be present.
   The concentration of contaminants  in leachate  will be affected by numer-
ous factors, including: types of fill  material,  amount of water  passing through
the fill,  and residence  time of water in the fill. Controlled experiments have
shown  that  high  BOD values,  organic carbon,  organic  nitrogen, ammonia,
chloride,  sulfate,    and sulfide  could  occur in  leachate  shortly  after  each
addition of refuse  to  a fill.(1) A steady decrease in  these  parameters was
noted  between applications  and wide variations  in  the  quality  of  leachate
from  the same landfill  have been  observed.  In the  Ski Mountain materials
would be added continously at a fairly uniform rate and all  areas of the fill
would probably receive  one  or more  layers  of  material each  year.  Under
these   conditions  the  quality  of leachate  might tend to stabilize.  However,
quality characteristics of leachate can  only  be established from  actual  field
experience.

-------
   The  amount of leachate anticipated  has  been based  on reported informa-
tion gathered  from experience with landfill operation in northeastern Illinois
where  the  leachate  has  been found to  be  about  15  inches of  water per
year.(' * For an initial  fill area of about one square mile, the average  leachate
flow was estimated at  approximately 0.7 million gallons  per  day (mgd).
   Leachate would be collected by the highly pervious blanket of rock on the
impervious glacial  till  foundation over the base area  of  the  mountain. Leach-
ate  percolating  down  from  the  fill would  flow horizontally through the
blanket  to  the   edges of  the fill  where  it would  be  collected  in  pipe
underdrains and pumped to the leachate treatment facilities.
   The  Illinois  Sanitary  Water Board  has  designated  the  Des Plaines  and
Illinois   Rivers adjacent to  the Ski  Mountain site  as an  Industrial Water
Supply  Sector and has established  water quality criteria for these streams in
its  "Rules and Regulations  SWB-8,"  a copy of which is in  Appendix B.  The
Illinois  State Environmental Protection  Agency advised  that  secondary treat-
ment will be required  for leachate discharged to these streams/2*
   The  proposed   treatment  facility  is an  oxidation ditch, a modification of
the  activated sludge  process. The facility is compact,  rugged, simple in design
and construction, simple  to  operate,  flexible,  provides  a  high   degree  of
treatment, and can  readily  be fitted   into the  landscape.  It  can be easily
screened and requires a minimum of operational buildings.
   The oxidation  ditch  method requires no primary sedimentation. Aeration is
provided in a  continuous shallow  ditch  where oxgyen is transferred  by  cage
rotors, a  mechanical  type of aerator. The rotor also imparts sufficient energy
to  the liquid to  maintain an  average velocity  of about  1.0  foot per second.
The ditch  would  have  a concrete lining as protection against erosion. Heated
housings would be placed over the  rotors  to prevent  ice  formation during
winter operation.

-------
   A final  settling tank  would  be provided for collection of solid material. A
sludge collection mechanism would be used  to remove  sludge  for  return  to
the ditch or for wasting as excess sludge.  Excess  sludge would be treated in
an  aerobic  digester and pumped to drying beds. Final solids disposal would
be on  the  land.
   The liquid effluent would be disinfected  and used to irrigate grass or crops
on the site, or discharged  to the Des Plaines or Illinois Rivers.
   The quality  of effluent from the oxidation ditch would be comparable  to
that from  an extended  aeration  facility and should meet the requirements  of
the Illinois Sanitary Water  Board for streams in an  Industrial  Water Sector.
However, if operating  experience  demonstrates that  the effluent  from  the
proposed treatment  facilities contains unacceptable  concentrations  of heavy
metals  or  other   contaminants,  chemical  or other  necessary   treatment
processes would be  provided to produce an effluent of acceptable quality.
   Runoff water from the  active working surface of the fill would be directed
to sedimentation ponds at the base of the fill. The runoff water would  then
flow through holding ponds constructed  by  damming small natural drainage
courses on  the site. From  the holding ponds,  the  water would be used  to
irrigate grass or crops on the site, or it would be discharged  to the Illinois  or
Des Plaines Rivers.
   Leachate collection  and  treatment facilities  were estimated  to  require  a
capital investment of $3,400,000.

     3.  Cost
       a.  Fixed costs.    Table V-2  is  a  summary of  the estimated initial
capital investment and annual capital and operating costs for constructing the
Ski Mountain,  excluding the cost of crawler tractors  and operators required
for spreading and compacting materials in the fill.  The costs in Table  V-2 are
relatively fixed  regardless  of quantity of  material received, while the cost for
crawler tractors and operations is variable  depending on  quantity of material
handled.
                                   V-16

-------
   The annual capital costs in  Table V-2  are based on  amortizing equipment
over its  normal economic life  and amortizing  other capital investment over a
30 year  period, at a 6 per cent rate of interest, with equal annual payments
of principal and interest. The  labor shown in Table V-2 is for operating the
disposal  facility one shift, 7 days per week, and for keeping the site  open at
all times to receive materials.
       b.  Variable costs.   Tractor requirements were  based on a 385 horse-
power crawler  tractor  being able to spread and  compact 700  acre-feet  of
rock or  600 acre-feet  of other inorganic material  annually, and one  standby
unit for each 6 operating tractors. The  17 crawler tractors and  14 operators
required  to spread  and  compact  the projected 1975  quantity  of inorganic
material  are estimated to  add the following costs:

              Capital investment                  $2,040,000
              Annual capital cost                    328,000
              Annual operating expense               403,000
              Total  annual cost                     $731,000

       c.  Unit  costs.   Figure  V-l shows the estimated variation in unit cost
for placing materials in  the  Ski  Mountain  due  to  variation in quantity. The
unit costs  include both  fixed  and variable costs.  Separate curves  are shown
for rock and  for other predominantly inorganic materials.  A  lower unit cost
is  indicated for rock because a  ton  of rock will occupy  less volume in  the
fill and will not require daily cover.

   C.   RETURNING ORGANIC MATERIAL TO THE LAND
   Under the  Ski Mountain concept,  the  organic fraction  of solid waste not
salvaged  for  re-use  would  be  placed on  land  and  tilled  into the top few
inches  of soil  where it  would  undergo aerobic degradation  and conversion  to
humus. This would be a  modification of the accepted practice of processing
refuse  into compost and placing  the  compost on  land  to  improve  plant

growth.  The major differences  would be that much of the  cost  of com-
posting  would  be eliminated,  stabilization of organic  matter would  occur in
the  soil rather than in a composting plant, and  the land would  be used as an
acceptor,  degrader,  and  stabilizer of wastes  rather  than  to  grow crops.
Organic  matter  would  be  added each  year  at  the  sustained  assimulative
capacity  of the  land so  that the land  would not  be lost to  future  crop
production or  other uses.
   This method  of returning organic  waste material to the land  has  not yet
been developed  and tested to the point  of  large  scale application. However,
research by Hart,  et al,  suggests  that  the concept  offers potential for pollu-
tion  free  disposal of wastes without  destroying the usefulness  of land.(1)(2)
The  researchers  recognize  that  much  additional  wprk will be  required to
develop  design and cost parameters.

      1.  Processing.   Residential,  commercial, and industrial refuse would be
processed  at receiving stations near the area  of generation  by shredding  and
separation of the  organic and inorganic  fractions.  Shredding makes the mate-
rial  easier to  handle, decreases  attraction   for  flies  and  rodents,  reduces
susceptibility to  blowing when  placed on the  land,  facilitates  mixing  with
soil, and increases the rate of stabilization.
   Shredded  organic  wastes would be spread on  the land and worked  into the
top  several  inches  of soil  on   a daily  basis,  except  when prevented  by
inclement  weather. Temporary  stockpiling would  be required when weather
prevented  direct  application to the soil.

     2.   Land  Requirement.   The projected  production of  organic waste in
Cook  County  is  4.7  million  tons in 1975  and  7.1  million tons in 1995.
Assuming an annual  application rate of 200 tons of organic material per acre,

the land requirement would be  about 25,000 acres in  1975 and  40,000 acres
in  1995.  These acreages include allowances  for  buffer strips  around the site
perimeter and some area for drainage control.
   Designation of a site or sites for returning organic material  to  the land was
outside the  scope  of this  report.  However, it  would  appear possible  to use
approximately  5,000 acres  of the mountain site  for this purpose during the
first 35 years of operation. Additional  farm land in the  same general  vicinity
might  be  acquired  to  meet  the remaining  requirement.  Returning  organic
material  to strip mine  land  would appear doubly advantageous as it would
obviate taking  existing  farm  land  out  of  production  and it  would help
reclaim virtually useless land.
   Research  conducted  at  the  University of Kansas  indicates  that  aerobic
stabilization  of shredded organic  solid wastes of residential origin  occurs  in
approximately  40 days during warm  weather and in approximately 120 days
during the winter/1}  If further  research  shows that shredded organic  wastes
can  be applied  to  the  same land more frequently than  once  a  year, the
required land area might  be substantially  reduced.
   Investigations by  MSDGC indicate  that nitrogen in  digested sewage sludge
is  the limiting  factor in the rate of sludge application  to  land  areas/2) On
the  other hand,  organic solid  waste is  deficient in  nitrogen.  For  these
reasons, some economy might  be realized  by applying both organic waste and
sludge to  the same land area.

     3.  Pollution Control.   The feasibility of returning organic material  to
the land is partially dependent upon  limiting  environmental  pollution to meet
established standards.

       a.   Air  pollution.   The primary potential hazard  to air quality would
be the emission of odors from wastes spread on  the land.

-------
   Available  research data  indicate  that  odors  from  the disposal operation
would  not be a  problem^!)  Odors  have been  reported not to be an appre-
ciable  problem  at  the solid  waste  project  in  Madison,  Wisconsin where
shredded wastes are placed in landfills several feet deep and are  not covered
or worked into the soil.(2)
   Blowing of dust and litter could  be minimized by  establishing  windbreaks
of trees and other plants around and through the site.

        b.  Water  pollution.    Absence of water pollution could be assured if
no  aquifer existed under  the site  or if existing aquifers  were protected by
impervious formations,  and if precipitation could be retained on the site and
off-site drainage excluded.
   Since much of the  land  in  Illinois is  not underlain by  a  usable aquifer,
placing  organic  material  on  such  land would  not endanger usable ground
water.  Precipitation  in  the vicinity  of the proposed  Ski Mountain site aver-
ages  approximately  33  inches per  year and reaches a  maximum  of approxi-
mately 48 inches at average reoccurrence  intervals  of about  50 years.  This
precipitation  is   dispersed  through   evaporation,  transpiration,  recharge  to
ground water,  and runoff. Evapo-transpiration is estimated to average approxi-
mately 75 per cent  of  the precipitation in an average year.  In  the absence  of
storage,  approximately 25 per cent of the  precipitation would be expected  to
occur as runoff  from the land area  in a  normal year. In an  extremely wet
year,  50 per  cent  of the rainfall might leave the land as runoff.
  Water quality   standards designate  the  Illinois River  downstream from the
Chicago Sanitary  and  Ship  Canal  to  the mouth  of  the  Fox  River as an
Industrial  Water  Supply  Sector.  Stream  standards for an  Industrial Water
Supply Sector are included in Appendix B.
  Runoff  from the  organic  disposal  area  could reach  the stream  by surface
flow  or by  percolation through the soil  and subsequently  discharge to the

stream. Water percolating through the soil  would be expected to be relatively
free  of bacteriological  and  organic pollution but  could  have  a  significant
concentration  of dissolved salts. Surface  runoff might  contain quantities of
chemical, organic, and  bacteriological pollution in excess of that allowed in
the  receiving  stream.  Design  procedures  necessary to  insure an  acceptable
quality runoff could be determined only by selecting a specific land area and
establishing a  test program to obtain data on runoff characteristics. It would
then  be possible  to  establish control procedures  and,  if  necessary, treatment
methods.
   It  is anticipated that the most  practical  means  for controlling  pollution
from surface runoff would  consist of impounding water that was unaccept-
able for discharge into  the  receiving streams.  The impounded water could be
returned  to the  land  by irrigation, held in  the  impoundment  until it had
stabilized,  or  until  flows  were  such  that  it  could be discharged  to the
receiving stream.

     4.   Cost.   In the absence of  a specific  site on  which  to  place organic
material,  the  land  cost  for  this  purpose was  estimated  on  the  basis of
purchasing 25,000 acres  of agricultural  land at  $1,000 per acre and  amortiz-
ing the cost of  $25,000,000 over a 30 year  period, at a 6  per cent rate of
interest, with  equal  annual  payments  of principal and interest. The capital
cost  of equipment to  operate the organic farm was  estimated at  approxi-
mately  $1,000,000.
   In  a  preliminary  economic  analysis of the  unit  processes  of  returning
organic material  to the land, Golueke and McGauhey, estimated  the operating
cost of field spreading and  tilling  at  approximately  $1.50  per ton.(1) The
estimate included spreading,  plowing twice, irrigating three times, and apply-
ing 300 pounds  of  nitrogen fertilizer  per acre for an annual  application of
200 tons  of organic material  per acre.

  The cost estimates herein make no allowance for treatment of surface or
subsurface  runoff, or for income  that might be derived  from crops grown on
the organics  farm.  It is not known at this  time  whether either would be a
significant factor  in the overall cost.

 VI.   SKI   MOUNTAIN  COSTS
   A.  TOTAL PROGRAM
   Table VI-1  is  a  summary  pf the  estimated  initial capital  requirements,
 annual  costs,  and  unit  costs  for  disposing  of the  total projected 1975
 quantities of Cook  County solid wastes through the  Ski  Mountain Plan as
 outlined in Section V.
   Estimates  were  based  on 1970 costs and include no allowances  for increas-
 ing  costs due  to  inflation, for taxes  or payments in lieu  of  taxes, nor for
 potential revenue  from salvage.  These  cost  factors, which are undeterminable
 now, should  be evaluated  and considered in the final design and financing of
 the  Ski  Mountain Plan.  Allowances  for legal, engineering,  and administrative
 expenses  and  interest  during  construction were  included in estimates  of
 capital requirements. Allowances of  5  per cent of annual costs were included
 for  administration  expenses.  Allowances of six  weeks  of  normal operating
 expenses  were  included  for  working  capital.  Annual  fixed  costs  for  the
 disposal  facility were  allocated  to  types of waste in accordance  with space
 requirements  in the mountain.
   Dredgings  were  considered to be delivered by others in a form suitable for
 placement in the mountain. Costs shown for dredgings exclude  transportation
 expense.

   B.   PROGRAM EXCLUDING ROCK
   Table VI-2  shows  the  estimated costs of  the Ski Mountain program  based
 on handling  the total  projected 1975  quantites of Cook County solid  waste
 excluding rock  from  the  Deep Tunnel Project.

   C.  PROGRAM  FOR 50 PER CENT OF  REFUSE
   Table VI-3  shows  the  estimated costs  of  the Ski Mountain program  based
on handling  only  50  per cent  of  the projected 1975 quantities of  Cook

VII.   ADMINISTRATION

   Although originally sendee was envisaged only for Cook County, the service
area of the proposed Ski Mountain facility need not be limited. With available
methods of  transportation,  a large portion of  the State of  Illinois could be
served. The large potential service area and location of the site outside the civil
jurisdiction of the governmental agencies of Cook County indicate the need for
a regional or State level agency to establish and operate the facility.

   No agency is presently organized and  empowered to manage a solid waste
disposal system of the scope  envisioned  in the Ski Mountain project. A new
agency  will  be required  and  special legislation will no doubt be needed to
authorize it.

   Initially, the functipn of the Ski Mountain agency will be construction of the
mountain.  This will involve  such major  activities as contracting with munici-
palities, counties,  and  private agencies  to utilize  the  facilities; acquisition of
land for the  mountain, transfer stations, and organics farm; providing transpor-
tation  systems for delivering  materials to  the  mountain and  organics  farm;
operation   of transportation  and  disposal systems; and collecting  sufficient
revenue to finance all costs of the program.

   As parts of the site or the mountain itself  are turned over to temporary or
permanent recreational  use, the agency will take  over the secondary function of
managing  a recreational facility. In  time, when construction of the  mountain is
complete,  the construction  phase will  reduce to a maintenance  activity and
recreation will become the primary function of the agency.
   To function effectively, the management agency will require certain powers,
including:
       — The power of eminent domain to allow  acquisition of property.
       — Authority to contract on a long-term basis with municipalities,
         countries, districts,  and other governmental agencies.
       — Authority to  enter  into long-term contracts with private  con-
         tractors, as may be necessary.
       — Authority  to  pay  for  capital  expenditures  through  debt
         financing.
       - Authority to levy service charges to pay all or a part of capital
         and operating expenses.
                                 VII - 1

VIII.    FINANCING
   A.   CAPITAL REQUIREMENTS

     1.   Capital Expenditures.    Financing of the Ski Mountain project will
require  that  sufficient  capital  be  obtained initially  to  pay  for all  land
purchase,  site development,  transportation  systems,  other capital  improve-
ments, and organizational expenses, and to provide working capital.

   As  indicated by the cost summaries  in  Section  VI, the capital required  to
establish the  Ski Mountain system  is influenced  by the types and  quantities
of materials to be handled  by the system.  Capital requirements at 1970 costs,
estimated at  $275,500,000  for handling the total projected  1975 quantities of
Cook County solid waste, are estimated to be only $142,000,000 for handling
50  per  cent  of the residential,  commercial, and industrial refuse and combus-
tible demolition debris.

   Determination of the actual capital requirement will be possible only after a
definite program has been formulated and the cost of facilities required for that
program has been ascertained by detailed estimates.

    2.   Sources  of  Capital Funds.    Potential  sources of capital  funds for
establishing the Ski Mountain system include bonds issued by the  Ski Mountain
agency  and grants from  the State or Federal government. Both the Federal
government,  under the Resources Recovery Act  of 1970, and  the State  of
Illinois,   under  the  Anti-Pollution  Bond   Act  of  1970,  have  authorized
grants-in-aid for improved  solid waste disposal systems, but the availability  of
grants  for the Ski  Mountain system can  be only  conjectured  at  this time.
Therefore,  the figures which  follow are based on financing  all  capital require-
ments through issuance of bonds, with no  allowance for grants-in-aid.

  General obligation and revenue  bonds are both  commonly used in munici-
pal or  local  public agency  financing of  capital  facilities. General  obligation
bonds  are  backed  by the  full  faith  and  credit  of the community and the
security  of the bonds is  guaranteed by  the ability  of the public  agency
issuing them  to assess and collect taxes.
  Revenue bonds  are repaid  from revenues collected  by the  public  agency
for providing  a service, and are not a lien on the property of the  agency  or
                                   VIII - 1

-------
the community. The agreed-upon bond  interest and principal payments  have
priority on  the  revenues  of the agency but  this is the only security of this
type of bond.

   Because  they  represent a lien against property, general obligation bonds are
usually  considered more secure than revenue bonds of the  same agency  and
therefore  command  a lower rate of interest. If the issuing  agency is newly
established,  with  little or  no  background  of management  capabilities  and
revenues to show, it may not find buyers  for revenue bonds at an acceptable
rate of interest.

   The investor in revenue bonds must set  up safeguards in the bond contract
to insure  that sufficient revenues will be available at all times to provide for
bond  interest  and retirement. In marketing revenue bonds, it is customary to
show  that  expected  net  revenues after  operating expenses will exceed bond
obligations by at least  40  to 50  per cent  during the  life of  the  bonds.
Accumulation  of  reserve  funds  to cover  fixed  charges in  the event  of
shortages  in  net  revenue  is  also  a usual requirement for  a revenue bond
agreement.  Because  of such requirements,  an agency may  find  itself under
severe limitations on  the use of its revenue.

   Because the Ski Mountain agency will be a new entity with no background
of  operations, revenues, or  management capabilities, it is unlikely that the
agency  would  be able  to market  revenue  bonds on  an  acceptable  basis.
Therefore,  general  obligation bonds will  be  the  most  probable  source  of
capital funds for establishing the  agency. After the Ski Mountain agency  is a
going concern,  it may  find  revenue bonds  a practical  means  for  meeting
subsequent capital requirements.
  B.   ANNUAL  REVENUE REQUIREMENTS
  After the Ski  Mountain project  is established, revenues must be sufficient
to meet  the  expenses of operating and  maintaining the system, make princi-
pal  and  interest  payments on  bonds issued  to  finance the project, set aside
any  stipulated bond  reserve  funds,  pay  any taxes, and  meet  any  other
payments necessary to the operation.

  As  shown  by  the  cost  summary in  Section VI,  the annual cost of  the
project is dependent  on the type and quantity of materials handled. Annual
                                VIII - 2

-------
costs are shown to range from  $87,100,000  for handling the total projected
1975  quantities of Cook  County  solid  waste  down to  $34,650,000 for
handling  only  50  per  cent of  the residential,  commercial, and industrial
refuse and demolition debris.


   C.  MEETING REVENUE REQUIREMENTS
   Three methods were  considered for obtaining  funds to meet the cost of
solid waste disposal under the Ski Mountain system:  general tax funds,  direct
charges to  those using  the  service,  and a combination of general tax  funds
and  direct charges.

     1.  General Tax Funds.   General tax fund financing has two principal
advantages  over  other  methods:  simplicity  and lower cost. Since no special
billing  and accounting  is necessary,  billing  and collecting costs,  as  well as
some overhead  expenses, are avoided.  Because all persons in the  area served
by  the  Ski Mountain  facility would  benefit  from  a cleaner environment
resulting from  a pollution-free solid  waste disposal  system,  it  is reasonable
that all  should help defray  the  cost  of the  facility.  This  could  be accom-
plished through general tax fund financing.

   The principal disadvantage of general fund financing  is that the  cost to the
individual taxpayer might not be in proportion to  the service  received.

     2.  Direct Charges.   A  direct charge for each  ton of material handled
by the Ski Mountain project has the advantage of requiring  those  who use
the  facility to  pay  for its full  cost. While a  direct  charge would  result in  a
reasonably  equitable distribution  of cost,  it  does  not  recognize  the general
benefit of a cleaner environment  that would  accrue to the entire  community
because of the project.
   Disadvantages of  direct charges  are that unit charges during the initial low
volume operation might  be  high  enough to  discourage use, and the  cost of
billing and  collecting would  be added  to  the cost of service.  However, this
cost need not be excessive.

     3.   Combination of General Tax Fund  and Direct Charges.  Because the
Ski  Mountain  would be  available  for use by all  within its service area and
because all  would  benefit from the  cleaner  environment  the facility would
                                VIII - 3

-------
promote,  it  is reasonable  that  all should help defray its cost. On the other
hand,  it is  also reasonable that those using  the  facility should  pay a higher
proportion of its cost than those who do not use it.

  A  practical  means for   achieving  both objectives  would  be  to  amortize
capital investment from general tax funds and to pay all operating costs from
direct  charges  levied  on  solid  wastes  handled by  the system.  The relative
proportions of amortization costs and operation costs are indicated  in  the
cost summaries in  Section VI.  Under  the combined  method of  financing,  31
to  37 per  cent  of the  cost would be paid  from general tax funds and  the
remainder from direct charges to those using the  disposal system.

  A possible advantage of  this  method of financing  over direct charges might
be  greater  use of the Ski Mountain system.  Since everyone  would share in its
cost,  there  would  be more incentive to utilize  the  facilities. Availability of
tax funds  would  also be  advantageous  to help  defray startup  expenses  and
operating  expenses  during  the  early  period  of  low-volume  operation when
charges for recovering all costs  through  direct charges might be high enough
to discourage use of the facility.
  The  combined  method   would  have the  same disadvantage as the direct
charge method in that the cost of billing and collecting would be added to
the cost of the service.

     4.  Recommended  Method.  A  combination of general tax funds  and
direct  charges is recommended  to provide revenue to finance the  Ski Mountain
system. Amortization of   capital investment  would  be  paid  from  general
tax funds,  and operating costs  would be  recovered through direct charges for
each ton of solid  waste received.

     5.  Charges.   Charges for  residential, commercial, and  industrial refuse
and other compressible materials should be based on weight. Charges for rock,
ash and similar materials of uniform density could be based on either weight or
volume.

  Estimated unit costs for various types of solid wastes presented in Section VI
are  the approximate charges required  to recover the full cost for disposing of
these  materials   under the  Ski  Mountain   system.   Table VIII-1  shows  the
approximate charges required to fully recover the estimated cost, and  charges
required if capital investment were amortized with general tax funds.

   D.  FINANCING OF  RECREATION  FACILITIES
   Purchase  of  all  land  for both  the  solid  waste  disposal  and  recreation
functions  would be  financed with general tax  funds as previously discussed.
Development of small lakes for  ultimate  recreational  use  would be  financed
as part of the  disposal operations, since these  impoundments would be used
initially for controlling erosion, sediment and water pollution.

   Skiing,  camping, and other  major  recreational and ancillary facilities could
be  provided either  by   private  concessionaires and  financed  through user
charges,  or such facilities could be provided  by the public  agency responsible
for management of  the  Ski Mountain and  financed by an appropriate com-
bination  of  general  tax  funds and  user  charges.

recreational and other legitimate uses, including their use in the final distribution of the water-borne
wastes of our economy. It has also been declared to be the public policy of this State to provide that
no waste be discharged into any waters of the State without first being given the degree of treatment
necessary to prevent the pollution of such waters.
                              WATER QUALITY CRITERIA

                                        ARTICLE 1

     Rule 1.01.    Introduction

     These criteria of water quality prescribe the qualities or properties of the waters of
the State which are necessary for the designated public use or benefit, and which, if the
limiting conditions given are exceeded, shall be considered indicative of a polluted condition
subject to abatement.

     These stream criteria shall be applicable to the Illinois River main stream, the DesPlaines River down-
stream from the confluence with the Chicago Sanitary and Ship Canal, and each tributary at its confluence
with the main stream.

     "Standard Methods for the Examination of Water and Waste Water", Twelfth Edition, 1965, American
Public Health Association, Inc. should be employed where applicable, but it is recognized that other approved
methods may be required in applying some of the criteria. The Illinois Sanitary Water Board shall designate
the alternate procedure in "Standard Methods", and approve any departure from these procedures,
with the concurrence of the Federal Water Pollution Control Administration.

      Rule 1.02   STR E AM SECTORS AND USES

     a) The Illinois River and the Des Flaines River downstream from the Chicago Sanitary and Ship
Canal to the mouth of the Pox River is designated as an Industrial Water Supply Sector. Industrial
Water Supply  criteria shall apply.

     b) The Illinois River from the mouth of the Fox River to the mouth of Bureau Creek is designated
as an Aquatic Life Sector. Aquatic life criteria shall apply.

     c) The Illinois River from the mouth of Bureau Creek to the Peoria and Pekin Union RR Bridge at
Peoria is designated as an Aquatic Life, Recreational and Public Water Supply Sector. Aquatic, Recreational
Criteria shall apply. The Public Water Supply Criteria shall apply at the point at which water is withdrawn
for treatment and distribution as a potable supply.

     d) The Illinois River from the Peoria and Pekin Union RR Bridge to the Mississippi River is designated
as an Aquatic Life Sector. Aquatic life criteria shall apply.

     Rule 1.03   MINIMUM CONDITIONS

     These Minimum Criteria shall apply to all waters at all places and at all times in addition to specific
criteria applicable to specific sectors.

  •  a) Free from substances attributable to municipal, industrial or other discharges that will settle to
form putrescent or otherwise objectionable sludge deposits; or which will form bottom deposits that may
be detrimental to bottom biota (such as coal fines, limestone dust, fly ash, etc.)

     b)Free from floating debris, oil, scum and other floating materials attributable to municipal, industrial
or other discharges in amounts sufficient to be unsightly or deleterious;

      Oils, grease and floating solids shall be reduced to a point such that they will not
create fire hazards, coat hulls ofwatercraft, injure fish or wildlife or their habitat, or will
adversely affect public or private recreational development or other legitimate shoreline
developments or uses.

      c) Free from materials attributable to municipal, industrial or other discharges producing color,
odor or other conditions in such degree as to create a nuisance;

     d) Free from substances  attributable to municipal, industrial or other discharges in concentrations
or combinations which are toxic or harmful to human, animal, plant  or aquatic life.


      Rule 1.04   FOR PUBLIC WATER SUPPLY and FOOD PROCESSING INDUSTRY
     The following criteria are for evaluation of river quality at the point at which water is withdrawn
for treatment and distribution as a potable supply;

     a) Bacteria: Coliform group not to exceed 5,000 per 100 ml as a monthly average value (either MPN
or MF count); nor exceed this number in more than 20 per cent  of the samples examined during any
month; nor exceed 20,000 per 100 ml in more than five per cent of such samples.

       For maintenance of well balanced Aquatic life habitats the dissolved oxygen content shall be not
       less than 5.0 mg/1  during at least 16 hours of any 24-hour period, nor less than 4.0 mg/1 at anytime.

      b)PH:

       No value below  6.0 nor greater than 9.0 at any time, and preferably between 6.5 and 8.5. Sampling
       shall be beyond  100 feet of an outfall sewer.

     Rule 1.06  FOR RECREATION SECTOR

     The following criterion is for evaluafion of conditioi s at any point in a recreation sector used for such
water contact activities as swimming and water skiing:

     Bacteria - Number per 100 mi by i«l F'ermenwuou or MF Techniques

     Bacteria: As determined by multiple-tube fermentation or membrane filter procedures,
     and based on a minimum of no,1 fe.w than five samples taken over not more than a 30-day
     period, the fecal coliform content of primary contact recreation waters shall not exceed
     a geometric mean of 200/100 ml, nor shall more than  10% of total samples during any
     30-day period exceed 400110'.) ml.

     (Primary contact recrea;io;> is ii-at-nded to  include activities in  which there is prolonged
     and intimate contact with the water involving considerable risk of ingesting water.)


     Rule 1.07   FOR INDUSTRIAL WATER SUPPLY SECTOR

     The following criteria are applicable to stream water at the point at which the water is withdrawn for
use for industrial cooling and processing, and at any point in trie industrial water use sector:

     a) Dissolved Oxygen: Not less than 3.0 rng/! during at least \ t  hours of any 24-hour period, nor less
       than 2,0 mg/1 at any tinm.

     b) pH: Not less than 6.0 not greatei thai! 9.0 at any time.

                                        '4-       B-IO

-------
 c) Temperature: Not to exceed 93 deg. F. at any time.

 d) Dissolved Solids: Not to exceed 750 mg/1 as a monthly avenge value, nor exceed 1,000 mg/1 at
   any time.

 e) All items of Minimum Conditions applicable to all waters at all places and at all times. (See Rule 1.03)

 0 Bacteria: The fecal coliform content of secondary contact recreation waters, as deter-
   mined by either multiple-tube fermentation or membrane filter techniques, shall not
   exceed a geometric mean of 1,000/100 ml, nor shall they equal or exceed 2,000/100 ml
   in more than 10% of the samples.

   (This criterion is intended to provide for water uses customarily described as "secondary
   contact uses", including boating, fishing, and limited contact with water incident to
   shoreline activities; in which contact with the water is either incidental or accidental
   and the probability of ingesting appreciable quantities of water is minimal.)

 Rule 1.08  IMPLEMENT A TION AND ENFORCEMENT PLAN

 1. The Illinois Sanitary Water Board, under the 1951 Sanitary Water Board Act as amended (Ch. 19,
   Par. 145.1 -145.18, IRS 1965), has the responsibility to control and prevent pollution in the waters
   of this State exclusive of the area embraced by Metropolitan Sanitary District of Greater Chicago.
   Authority to adopt and enforce water quality standards within the Metropolitan Sanitary District is
   contained in the recently adopted HB 1177,75th General Assembly.

 2. The Board adopted the criteria, Rules and Regulations SWB-8, December 1,1966 as standards of
   water quality for the waters of the Illinois River and the Des Flaines River downstream from the
   confluence with the Chicago Sanitary and Ship Canal and each tributary at its confluence with the
   main stream. AH waters will be required to meet the standards for the appropriate public and indust-
   rial water supply, aquatic life, recreational and agricultural uses. Compliance with these standards
   will enhance the quality of waters within these streams.

   Waters whose existing quality is better than the established standards as of the date which
   such standards become effective will be maintained in their present high quality within
   the powers granted by the "Illinois" water pollution control  statutes. Such waters will not
   be lowered in quality unless and until it has been affirmatively demonstrated to the Federal
   Water Pollution Control Administration that such change is justifiable as a result of neces-
   sary economic or social development and will not interfere with or become injurious to,
   any appropriate beneficial uses made of, or presently possible-in. such waters.

3. The minimum weekly flow, which occurs once  in 10 years, will be used in applying the
   standards.  The Board plans to require compliance with the bacteriological standards for recreation
  during the recreational season of April through October inclusive. It is recognized that there are uncon-
  trollable sources of bacterial pollution other than that of sewage treatment plant effluents.

4. Drastic or sudden temperature changes will not be permitted. The Board will insist upon
   controlled changes in temperature not to exceed 2 deg. F. per hour, nor more  than a
  5 deg. cumulative change from natural water temperature.

5. The Board collects samples bimonthly from various locations on streams in the Illinois River Basin.
  Monthly samples are collected from most of the Illinois River stations and weekly samples from  one
  station during May through October. Additional stations are being added as needed and two electronic
  stations are programmed for the Fall of 1967.

6. Rules and Regulations, SWB 2, require the certification of waste treatment plant operators. The prompt
  and regular submission of monthly operational reports is required to enable evaluation of effluent quality.
  Certification and record of operation report submissions are recorded in a computer system to facilitate
  periodic data processing. The frequency of inspections of wastewater treatment plants by representatives
  of the Board have been increased and will be increased more to insure compliance with the standards.
                                       B-H

-------
 7. Secondary treatment resulting in effluents ranging from 20 to 40 mg/1 five day BOD and 25
    to 45 mg/1 suspended solids  must be provided by all municipalities, including disinfection
    of the effluent.

 8. All industries will be required to provide a degree of treatment or control that is equiv-
    alent to that required of municipalities. I n some instances supplemental or advanced waste
    treatment in excess of secondary treatment may be necessary.

 9. It is the plan of the Board that, where needed, the control of pollution caused by combined sewer
    overflow or storm flow bypassing at sewage treatment works be provided at the time of improvement
    or expansion of treatment works. The separation of combined sewers or special treatment works in
    some instances, the reduction of nutrients and provision of tertiary treatment should be accom-
    plished, where deemed necessary, within the next ten yean, or as practical technical methods
    are developed.

10. Treatment Requirements and Effluent Criteria

    In order to establish a basis for treatment works design, municipal and industry representatives and
    consultants frequently inquire regarding the limits or effluent standards that must be met. The adop-
    tion of stream water quality criteria as required by the Federal Water Quality Act of 1965(PL 89-234
    amendments to PL 84-660; 33 U.S.C. 466) emphasizes the need to relate stream quality to effluent
    quality and treatment requirements. The expressed goals established by this Act are to protect and
    upgrade water quality; any wastes amenable to treatment or control must receive the best practicable
    treatment or control prior to diiicharge into any interstate water. The same goals have been, and con-
    tinue to be, basic under the Sanitary Water Board Act for all waters of Illinois. Both the Federal  Law
    and the Illinois Act prohibit the use of any stream or portion thereof for the sole or principal purpose
    of transporting wastes.

    a. All municipal or industrial facilities for treatment of deoxygenating waste shall provide at least
     secondary biological treatment, or advanced waste  treatment, adequate to reduce the organic
     pollution load of the treatment works effluent at the final treatment structure in accordance with
     effluent guidelines in paragraph 11, below. A final treatment structure is considered the last point
     of access before discharge to waters of the State. Effluents shall meet all criteria expressed in Item
     b below.

    b. All faculties for the treatment of sewage, industrial wastes, or other wastes shall provide for the
     following:

     1) Substantially complete removal of settleable solids.

     2) Removal of all floating debris, oil, grease, scum, or sludge solids.

    3) Removal of color, odor, or turbidity to below obvious levels.

    4) Removal of heavy metals, or of toxic and odor producing substances in accordance with the levels
     of constituents and properties determined by the Board.

   c. Storage facilities for materials; which are hazardous to health and welfare, and for oils, gases, fuels, or
     other materials capable of causing water pollution if accidentally discharged, shall be located so as to
     minimize or prevent any spillage or leakage that might result in water pollution. Structures and devices
     to contain spillage, such as catchment areas,  relief vessels, or entrapment dikes, should be installed at
     existing facilities, shall be installed at all new facilities, and shall be required following any discharge
     resulting in pollution.
                                                B-12

11.  Guidelines Regarding Range of Treatment

   a. Secondary treatment resulting in effluents ranging from 20 to 40 mg/1 five-day BOD and 25 to
     45 mg/1 suspended solids is acceptable on the Illinois River and lower Des Plaines River. Tertiary
     or other advance treatment or modifications of conventional treatment will be specified for all
     intermittent streams and small or low flow streams, and shall include effluent disinfection at least
     through the recreational season of April through October.

  Disinfection with up to lmg/1 of chlorine residual in the effluent to reduce fecal Coliform to 400 or less,
  where necessary for primary contact waters or to 2000 or less forsecondary contact waters.

  Bypass flows in excess of waste treatment works capacity shall be given primary treatment, and chlorination
  if necessary, in auxiliary facilities.

 c. Within design limitations, operation shall be of such quality to obtain the best possible degree of treat-
   ment from all treatment works. Every effort must be made to eliminate all system bypasses and overflows,
    otherwise measures must be taken to provide treatment units such as lagoons, detention or holding basins,
    and chlorination. Installation of new combined sewers are prohibited. Existing combined sewer systems
   should be patrolled;  overflow regulating devices  shall be adjusted to convey the maximum practicable
    amount of combined flow to treatment facilities. Excess infiltration into the sewer system should be
    eliminated to keep dry weather flow within design limits of conduits and treatment works.

                             APPENDIX C
                DATA ON  INVESTIGATED  SITES  FOR
       A  SOLID  WASTE MOUNTAIN  AND  RECREATION  AREA
                    IN SOUTHWEST COOK  COUNTY
   The following is the basic data considered in selecting and evaluating investi-
gated sites for a solid waste  mountain and recreation area. Matters common to
two or more sites are discussed under a number of topic headings relating to
site  suitability.  Detail information  peculiar  to the individual sites is presented
under the same headings in a tabulation following the general discussion.

SIZE AND CONFIGURATION
   Each of the investigated sites has an area  in excess of 3,200 acres. Sites  1, 4,
and  5  each  exceed 5 square  miles while  Sites 2  and  3 each encompass an area
of approximately 6 square miles.  Each site  exceeds 3 miles in length; however,
their width and configuration vary. Sites 1  and  4 both average approximately
1.5 miles in width. Site 2 is  1.25 miles wide at its north boundary and 3 miles
wide at its south boundary.  Site 3 is  2 miles in  width. Site 5 averages approxi-
mately  1.8 miles  in width. The two larger sites (2 and 3) would permit greater
design   flexibility  for  the  proposed solid  waste mountain  and recreation
facilities
   Depending upon permissible landfill  side slopes,  site wicuh n;ay limit rhe
maximum height  of fill on some  sites to less than 1,000 feet. For example, an
average side slope of 4 to  1 on a 1,000-foot high  fill would require a base width
of 8,000 feet. Such a fill  could not be  placed on Sites 1 or 4 as they are  only
8,000 feet wide and some  setback of the  fill would be necessary.
EXISTING STRUCTURES ON SITES
  AH of the investigated sites are located in rural Cook County. Site 1 embraces
about 200 single family residences (including farm homes) and 7 non-residential
structures. Approximately  half of these structures are sub-standard. No attempt
was made to catalogue the number of farm accessory buildings on any of the
sites.  Site  2 includes  only  about  100  single  family residences  and  2  non-
residential structures. With both Westhaven and Fernway Park located within its
boundaries, Site  3 encompasses more structures  than  all the other sites com-
bined. Approximately 510 single family  residences and 6 non-residential struc-
tures  are  located  within  Site 3.   The  majority of  these  structures   are
                                     C-l

-------
sub-standard.  Site 4  has  the  fewest  structures with  only  35  single  family
residences and 2  non-residential structures. Site 5  has  118 single family struc-
tures and 6 non-residential uses.

   None  of  the  sites  has extensive  commercial  or  industrial usage.  A  few
scattered public buildings are located on all the sites. Sites 2, 4, and 5 contain
cemeteries; however,  these are not extensively  developed  at  this time  and
should  not  create  insurmountable  difficulties.  Site 5  encompasses  5  major
public uses: 2  country  clubs, a  home for the  aged,  a scout  camp,  and a
cemetery.

   Site 3  contains 2  schools:  The Fernway  School and  the Hollstein School.
Site 2 also contains 2 schools.  Sites 1, 4, and 5 contain no schools.
   All of the sites are traversed by utilities, principally gas and oil pipelines and
high voltage power  transmission lines.  In most instances, these utilities  would
have to be rerouted around the site.
   Major streets traverse  all the sites.  The ultimate design  for  the completed
landfill  will determine  which streets would have to be entirely eliminated  and
which would be rerouted to serve local traffic.

LAND VALUE
   Approximate  land  value  information indicates that most of the undeveloped
land in  the investigated sites is currently valued in the range of $3,000 to $4,500
per  acre.  Small  areas  of residential and commercial development are valued
considerably higher and will significantly  affect the  overall land cost of the
different sites.

ACCESSIBILITY
   The distance  and accessibility of  the disposal site from areas of solid waste
generation are  major factors in the overall cost of solid waste disposal. Char-
acter of  highway haul  routes largely determines whether the hauling operation
will  create a nuisance.  Fortunately,  Sites 2,  3 and  4 now have excellent access
via the  interstate  highway  system. The same  highways  provide haul routes  to
Site 1,  but several miles of undesirable travel  on  two-lane highways would be
required  to reach the  site  from the interstate system. Proposed express high-
ways may  provide excellent access to  Site 1 in the future. The proposed South
Suburban Freeway may bisect  Site 5  when it is constructed.
                                      C-2

-------
   Sites 1 and  2 have direct access to the Wabash Railroad and Site 3 has direct
 access to the Chicago,  Rock  Island and Pacific  Railroad. Site 4 is l/2 mile north
 of  rail and Site 5  has rail  access  within  '4 mile.  Subsequent  transportation
 studies will determine whether railroads will be a feasible means for delivering
 solid wastes to the disposal sites.
   All of the  sites  are several miles from water  transportation routes except
 Site 5 which has access to the Calumet Sag Channel and the Chicago  Sanitary
 and Ship Canal.
   The  sites are  15 to 20 miles  from the initial stage of the proposed  deep
 tunnel project, via the interstate highway system.
   Passenger transportation by  rail to the solid  waste mountain  and recreation
 area  would  be beneficial  in  making the  recreation facilities available to the
 maximum number of people.  Under the C.A.T.S. "Alternate Transit Network"
 the  Wabash Railroad,  which  has direct access  to Sites 1 and 2, would  be a
 commuter  railroad.  However, under the  C.A.T.S.  "Recommended  Transit
 System",  no passenger  service via rail would be available to Sites 1, 2, 4,  or 5.
 Site 3 would be served by a  local railroad under the C.A.T.S. "Recommended
 Transit System".

 RELATIONSHIP TO OTHER LAND USES
  All  of  the  investigated  sites are  located  within  the Metropolitan  Sanitary
 District of  Greater Chicago.  Site 4  includes one of  the  District's proposed
 sludge disposal sites.

  Site  1 abuts existing Forest Preserves on both the north and the east. Site 2
 includes 1.5 square miles  of  undeveloped Forest Preserve  ground. Site 3 abuts
 this  same area. Site 4 includes approximately one square mile of undeveloped
Forest Preserve ground in  its  northeast comer.  The Forest Preserve properties
included in  Sites 2  and 4  are  necessary to provide sites of adequate  size and
suitable shape.  Site 5 abuts Forest Preserve holdings along its east boundary.
  Site 1 contains  considerable  residential  development and its east side borders
the Village  of Orland Park. Site  3  contains  the Fernway Park and Westhaven
residential developments.  Site 4 abuts the  west side of the Village of Matteson.
Site 5  is adjacent  to  the  Village of Lemont.  Site 2 is  the least exposed to
existing urban  development. Residents of  the  sites and  of the adjoining villages
will probably strongly oppose the  solid waste  mountain.
                                   C-3

-------
   Sites 1, 4 and  5 would be the most compatible with  the  proposed NIPC
Finger Concept of urban development,  as they are in  proposed buffer wedges
between development  corridors. Sites 2 and 3 are in the proposed development
corridors and would not be compatible with the Finger Concept.

WATER POLLUTION POTENTIAL
   All sites are  underlain by a creviced dolomite aquifer, and over a major part
of all sites except Sites 3 and 5 a sand and gravel aquifer overlies the dolomite.
These  aquifers  are a valuable  natural resource and  should be protected from
pollutants which might leach from a solid waste landfill.
   It is  probable that reasonable  protection of the aquifers would be provided
by the approximately  50 to 150 feet of relatively impervious glacial till which
extends from  the  ground  surface to the top of the aquifers. Some glacial till
would  probably be used  for  cover  on  the  refuse  fill  reducing the amount
available for protection  of the aquifers. Collection  and treatment  of leachate
from the solid  waste fill would also probably be necessary  to control pollution
of both ground water and surface water.

  The  preceding evaluation is  based primarily  on generalized information  con-
tained  in  publications of the  Illinois  State Geological  Survey and State Water
Survey. Subsurface  drilling  and  investigations will  be required to  more defi-
nitely evaluate  the water pollution potential of the sites. It may be possible to
limit such  detailed investigations  to  one or two  sites  selected  on the basis of
other factors.

DRAINAGE
  Where possible,  sites  were selected in the upper portion of watersheds to
minimize the amount of runoff to be diverted around the refuse fill. Ownership
of all  drainage area tributary  to  a site  would be advantageous  as this  would
permit filling in a manner to facilitate drainage.
  All sites  are considered suitable from the standpoint of drainage. However,
some sites will be more difficult to drain than others.

FOUNDATIONS
   Soil  borings  and other subsurface investigations will be required to determine
whether  the subsurface  formations will  adequately  support a  1,000-foot  high
solid waste mountain, and the structural design parameters for the solid waste fill.

-------
   Since  each of  the sites is  underlain  by  substantial  depths of glacial till,
formation  conditions on all of the sites  are expected to be similar except for
variation in depth of till. The load bearing  capacity of the  subsurface form-
ations may control the maximum slope of solid waste fill which, in turn, could
limit  the maximum height of fill.
   It  may  be possible  to limit  subsurface investigations to one  or  two sites
selected on the basis of other factors.

OBSTRUCTION TO AIR TRAFFIC
   A  Federal  Aviation  Administration  representative  advises  that:  (l)a
1,000-foot  high structure anywhere within 40  miles of Q'Hare Airport  would be
considered  an  obstruction  to  Instrument  Flight  Rules  (IFR) navigation,
(2) structures 500 feet in height and higher within 2 miles of a major highway,
river  or other prominent topographic feature would  be considered an obstruc-
tion  to Visual Flight Rules  (VFR) navigation, (3)  the  FA A has successfully
blocked installation of some radio and television antennas in the Chicago area
which would have interfered with  air traffic,  and (4) if a proposed obstructing
structure were essential  for  the  public welfare, the  FAA might accept it and
adjust operating procedures accordingly.

   All of the sites are within 30 airline miles of O'Hare Airport and within  2
miles  of  existing highways  or  proposed  express highways;   therefore,  a
1,000-foot high structure would  probably be  considered  by  the FAA to be an
obstruction to both IFR and VFR navigation.
   Inquiry  has been made to the Aviation Department of the City of Chicago as
to whether a 1,000-foot high mountain on any of the  potential sites  would be
compatible with the City's long-range  aviation program.  A reply had not been
received when this was written.

SITE RATING
  From the preceding evaluation, the sites are rated in order of suitability for a
solid  waste mountain, as follows: 4, 5,  2,  1, and 3. However, none of the sites
is considered  really suitable for the solid waste disposal operation covered by
this study. There is serious doubt  that any of the sites could be acquired over
the objections of the public arid the numerous agencies that would be affected
by use of the  land for solid waste disposal

 Dear Mr.  Dalton:

 We believe that  the effects  of  the proposed  1000-foot high solid waste
 mountain  on air  traffic in the  Chicago area  should be determined as soon
 as possible.

 The  normal method for  determining  whether  a  proposed  tall structure will
 be a significant  hazard to air  traffic is  to submit FAA Form 7460-1 to the
 Federal Aviation Administration of the U.S.  Department of Transportation,
 with a request that an immediate study be  made of  the matter.   Since the
 Metropolitan Sanitary  District  is  the sponsoring agency for the proposed
 solid waste mountain,  we  believe it appropriate that  the District submit
 this form and request  to  the Federal Aviation Administration,

 Accordingly, we have filled  in  the appropriate information on  a copy of
 FAA  Form  7460-1  and are enclosing  this form  and two blank copies of it.

 The  data  shown on the  form are  merely our  suggestions and may  be modified
 as you see fit.

 Please complete one of the blank forms and submit  it, together with a
 request for an immediate  study, to:

             Mr. M.  L. Kolhler, Chief
             Air Traffic Branch

Dear Mr. Kolhlwri

Subject i  Solid Waste Disposal  Study (Ski  Mountain)

The Metropolitan Sanitary District  is  preparing  an
engineering design report for a posnible solution to
the poll-? vast*" 3i*p«Hal problem of rook County.

This report is being prepared because  ttu*  District does
anticipato a  substantial amount of  excavated  naterinln
fror our T'rono»ed capital ir.provi.m«ntfi r^o^*"5 *o*" tho
next ten years.  It is estimated thnt  we nay  have approxi-
mately  nix million cubic yards  of rook •xcavated annually
from rock tunnels, and we art* actively purpuino  a solution
to the problem of! ditpouinc of  this rook material so as  not
to create other environmental problem* within Cook County.

In order to make certain that our excavation  disposal
solution is conrvxtibia with solution*  of other agensies,
w« have established a steering  coBimittae composed cf repre-
sentatives indicated on the attached list.

One of the possihle .'Jolutiona to the solids disposal
problem ia to develop a mountain composed  of  solid materials,
The ultimate development will have  a tremendous  recreational
potential and will be developed in  such *  manner so as to be
froe of any environmental hazard.

We have received a grant pf $140,000 from  the Department of
Health, Education and Welfare,  Bureau  of Solid V7aste Manage-
ment, Public Health Service, Grant  number  oo-l-ui-00163, in
order to develop a d«sicjn report for this  work.

'fork nan progressed on this design  report; however, wo do
want to determine what effect,  if any,  the proposed
mountain will have on air traffic in the Chitwgo area if

Mr. Forrest C. Neil
Acting Chief Engineer
The Metropolitan Sanitary District
of Greater Chicago
100 East Erie Street
Chicago, Illinois  60611
Dear Mr. Neil:

We have completed an aeronautical study of the proposed solid waste
mountain and recreation area to be constructed »»  described  in the
FAA Form 7460-1, Notice of proposed Construction or Alteration,  that
you submitted to us on 10 November 1969.  The study was conducted
within our organization and was not circularized to aviation interests
as agreed upon in your telephone conversation with Mr. Keith Potts
of our office on 17 November 1969.

Our study disclosed that the proposed facility would have  the following
effect upon aeronautical operations and procedures in the  Chicago
Metropolitan Area:

1.  It would shield the new Chicago South radar site that  we are
installing to enhance air traffic control in the Chicago area.   This
would eliminate any low angle coverage to the west of the  proposed
mountain from approximately 280° to 300°, resulting in a mandatory
relocation of the new radar.  This radar site is very critical and
vital to aeronautical operations in the Chicago area.  Radar site
acquisition in this area is most difficult and the present site  is
the only one we have found suitable to meet requirements.  This
proposed solid waste mountain would, therefore, jeopardize our radar
planning.

2.  It will be close to the radar microwave link repeater  path between
the LaGrange, Indiana radar site and the Chicago Air Route Traffic
Control Center at Aurora, Illinois.  There is a very good  chance that
the mountain will have an adverse effect on the performance  of the
LaGrange radar remoted to the Chicago AKTCC.

-------
3.  It will require that the initial departure altitude for aircraft
departing the Midway Airport be increased from 2000 feet MSL to 3000
feet MSL.  As a result of this increase, the minimum altitudes for the
O'Hare parallel Runway 32 instrument approach procedure would be
increased to 4000 feet MSL for Runway 32L and 5000 feet MSL for
Runway 32R.  This would place the aircraft above the glide path
intercept point and would negate the procedure.  Inasmuch as
2000 feet MSL is the only altitude available for aircraft departing
Midway when Runway 32 approaches are in progress at O'Hare and the
fact that it is imperative that parallel 32 approaches at O'Hare
be retained, independent operations at Midway and O'Hare would be
eliminated.  This results in a substantial adverse effect on both
O'Hare and Midway Airports.

4.  It would require that Federal Airway V69 V173 V262 minimum
obstruction clearance altitude be increased from 2000 feet MSL to
2800 feet MSL and the minimum en route altitude be increased from
2500 feet MSL to 2800 feet MSL.  Present procedures provide for
the use of 2000 feet MSL in this area and this would be increased
to 3000 feet MSL, thus the loss of a cardinal altitude.

5.  We are presently in the process of establishing a full instrument
landing system (ILS) for Runway 4 at Midway.  The localizer outer
marker site (LOM) is planned to be located 4.4 to 4.5 miles southwest
of Midway and cannot be relocated because of existing structures.
The proposed mountain would be located in the procedure turn area
of this new procedure and would be of such height as to require
an unacceptable descent gradient after the outer marker site and
would negate the whole system.

6.  Inasmuch as the proposed facility would exceed 500 feet above
ground, it would be in conflict with Public Law 85-726, PAA Act of
1958.  The Act defines "navigable airspace" as that "airspace above
minimum altitudes of flight prescribed by regulations issued under
this Act, and shall include airspace needed to ensure safety in
take-off and landing of aircraft."  Minimum flight altitudes are
prescribed by regulation in Section 91.79 of the Federal Aviation
Regulations.  Generally speaking from a Visual Flight Rules
standpoint, it must be considered that the navigable airspace
include all airspace 500 feet and more above the surface and that
airspace below 500 feet required for flight over sparsely populated
areas.  In view of the fact that the proposed facility would be
located in an area that is used extensively for Visual Flight Rules
traffic transitioning to and from the airports in the Chicago
Metropolitan Area to outlying points, and would occupy the airspace
                                     D-7

-------
which has been declared to be "navigable airspace", any aircraft
attempting to use this airspace would run a risk of colliding
with the proposed facility.  Therefore, the structure would have
an adverse effect upon Visual Flight Rules operations in the
Chicago area.

In consideration of the foregoing, we have determined that the
proposed solid waste mountain could have a substantial adverse
effect upon aeronautical operations and procedures in the Chicago
Metropolitan Area.

We regard the navigable airspace as a limited national resource
and have been charged by Congress with administering it for the
public benefit.  While the aviation community is the principal
user, there are others who have legitimate requirements for the
use of airspace.  When conflicts of interest over the use of
airspace arise out of proposals such as yours, we emphasize the
need for conserving the navigable airspace, for protecting air
navigation facilities and aeronautical procedures, the encroachments
of which would preclude them from performing their operational
functions for the use of aircraft.  However, every effort must be
made to satisfy both interests.

Therefore, we request that at such time as plans for the proposed
mountain become more definite, that you notify us and at that time,
we will initiate a full aeronautical study, which will include
circularization of the proposal to all interested persons and issue
an official airspace determination.

Additionally, we would like to suggest that you coordinate the
subject proposal with the City of Chicago, Department of Aviation,
concerning their plans for siting of future airports in the Chicago
Metropolitan Area.

If we may be of any further assistance or service in this matter or
if you have any questions, please do not hesitate to contact us.

Sincerely,
Chief, Air Traffic Branch, CHI-500

Dear Mr. Kfrkpatrick:

Your letters of October 8 and  October 28 furnished information
concerrvi-ng studies directed  toward the construction of a 1000-
foot high solid waste mountain in southwest Cook County, and
inquired concerning the compatibility of this proposal with the
long range aviation program  of the City of Chicago.

The information forwarded with your correspondence has been
circulated to the departments  of the City concerned with aviation
planning, requesting the! r advice on the impact of the proposal
you suggested.  The replies  indicate that the development of a
1000-foot high mountain in any of the general areas under con-
sideration would conflict with the development of sites now under
consideration for a future major airport.  Construction on the
proposed project prior to the  selection of a site for a major
airport could result in the  elimination of a site for possible
airport development.

A meeting with you to discuss  the matter is not considered to be
necessary.  However, if you  desire to discuss the matter further,
a meeting would be scheduled at your convenience.

With kindest regards,

                                 Sincerely,
                                 John B. W. Corey

Dear Mr. Neil:

At your request, we submit our version of the outcome of discussions held
with the FAA concerning the expected effect of the solid waste mountain on
air traffic in the Chicago area.  Please review these comments carefully
in the light of your notes and recollections, as well as those of Mr. Scapiu,
so that the meeting summary will present a true picture of the situation to
the sub-committee.

The meeting was held at 1:30 p.m., February 18, 1970 in the FAA Chicago Area
Office at Des Plaines.  Those in attendance were:
     John Scapin
     Forrest Neil
     Bill Mercks
     Keith Potts
     Harry Mclntyre
     Carl W. Johnson

Our understanding of the position taken by the FAA officials with regard to
the several items discussed in their letter to you, dated December 9, 1969,
is summarized below:    <

     (1)  It was pointed out that site selection for radar was a
          difficult problem and that the site in question had been
          selected after much careful study.  The purpose of this
          installation is to improve radar coverage of traffic from the

                     small airports in the Chicago area, as well as from the major
                     commercial airports.  The radar will be mounted close to the
                     ground and beamed upward at a slight angle to eliminate, as
                     much as possible, interference from structures on the ground.
                     Because of ground interference, it was not considered practical
                     to mount the radar atop the mountain.

                     The radar display will be installed remotely at the control
                     center.  The question was raised concerning the installation
                     of another radar to cover the sector blanked out by the
                     mountain.  This is possible but not desirable since it would
                     require another radar display.  The technology is not yet
                     available to combine displays from two radars.  Development
                     effort is being expended on this problem and it is conceivable
                     that a multi-radar display will be developed.  If and when this
                     is available, an additional radar might be sited to cover the
                     blind area.

               (2)   The micro-wave path between LaGrange, Indiana, and Aurora,
                     Illinois, may require modification, possibly an additional
                     repeater station to carry the path around the mountain.  This
                     would cost $50,000 i plus land for the site.

               (3)   The fact that the increased altitude required at Midway to
                     clear the mountain would also raise the approach altitude to
                     Runways 32R and 32L at O'Hare means that simultaneous landings
                     on 32L and 32R would experience interference, thus cutting
                     capacity of these approaches.  It was estimated that approaches
                     in the 32 direction are necessary about 302 of the time.
                     During such periods of interference, stack-ups would occur
                     and traffic would be affected not only at Chicago but all across
                     the country.

               (4)   The loss of a cardinal altitude means that a proportionately
                     smaller amount of traffic could be accommodated.

               (5)   The mountain would defeat the purpose of the 1LS for Runway
                     4 at Midway.

               (6)   By being over 500 feet above the ground, the mountain would
                     extend into airspace used by a large volume of small, private
                     aircraft in skirting the heavy Chicago area traffic and, in
                     effect, would reduce the air space.  It is particularly important
                     for pilots not familiar with the area.  This is not an insur-
                     mountable problem but would probably require that the mountain
                     be well-lighted to outline the obstruction at night.

        Conclusion;   It was indicated that unless Midway was abandoned, FAA would
        not accept the mountain at the location proposed.  It was indicated that
        there were probably no other sites in this general area of Cook County which
        would not have basically the same objections.  It was believed that Item 1
        was a problem that might be solved by a monetary expenditure along with
        advanced technology; Item 2 could be solved by the expenditure of funds;
        Items 3, 4 and 5 were insurmountable unless Midway Airport was abandoned;
        and Item 6 could be compromised.

        The subject of a future Chicago airport was discussed in general, and the
        FAA representatives expressed the opinion that if the facility was sited
        somewhere to the south of the mountain site as presently envisioned, the
        mountain would very likely cause a hazard to its operations.

LACK  ft VEATCH
        Mr. Frank Dalton
        Metropolitan Sanitary District
          of Greater Chicago               - 2 -                  March 17, 1970
        A copy of the Black & Veatch letter of February 19, 1970, reporting results
        of the meeting held with the Federal Aviation Administration (FAA) on February
        18, was passed out.  Mr. B. K. Potts, an FAA representative, indicated that the
        consultants' interpretation was substantially correct.  He stated that a solid
        waste mountain at the Leraont Township site with top elevation up to elevation
        1049 MSL (300* + above ground) would pose no problems for air traffic, but that
        a 500' mountain (top elevation 1249' MSL) would have to be studied and would
        pose some problems to FAA; although, the problems would be much less severe
        than for a 1000' mountain.  It was indicated that much the same problems would
        be posed by a 1000* mountain located at any of the sites considered in southwest
        Cook County.  Mr. Potts also pointed out that the mountain would have effects on
        the proposed new Chicago airport which is expected to be located somewhere south
        of Cook County, but that these effects could not be determined until an airport
        site has been selected.

        Further discussion indicated that a solid waste mountain, possibly as high as
        elevation 1500* MSL; might be tolerated by the FAA at certain locations in
        northwestern Cook County.

        It was concluded that there are two alternatives available:  construct a
        mountain substantially less than 1000* high in Cook County; or build the
        1000' mountain outside Cook County.  The merits of basing the study on sites
        in Cook County and outside Cook County were discussed.  It was the consensus
        that, if a definitive study of a solid waste mountain outside Cook County was
        to be undertaken, the State of Illinois should become involved in sponsoring
        the work.

        The consultants noted that while there may be suitable sites for a 1000' solid
        waste mountain along the Illinois Waterway outside Cook County, the feasibility
        of skiing facilities would be reduced by a shorter season and the necessity for
        snow-making more of the time if the site were located south of Cook County.
        Investigations show that ski slopes in Cook County have a substantially shorter
        season than those only 60 to 70 miles further north in southern Wisconsin.

        The Consultants stated that about $95,000 had been committed to date on the
        study, leaving some $70,000 available for the Consultant's completion of the
        study.

        It was noted that if the direction of the study is altered to cover one or
        more smaller mountains, this change should be cleared with the Board of the
        Metropolitan Sanitary District: of Greater Chicago and with the Bureau of
        Solid Wastes.

        The consultants were instructed to provide the Committee with preliminary
        findings by April 17 on:

               1.  The feasibility of a mountain 500* or less in height at site 5.

               2.  Whether there is a site in northwest Cook County that could
                   accommodate a 500* + mountain.

               3.  Approximate distance it will be necessary to go to find a site
                   for a 1000 ' high mountain which will not interfere with air traffic.

          It was noted that private haulers represented by the Chicago and Suburban
          Refuse Disposal Association collect more than half of the solid wastes in
          Cook County and have a vital interest in the future disposal program, and it
          was suggested that it would be appropriate to have a representative of the
          Association on the Steering Committee,

          To be certain that the entire Steering Committee is fully informed, it is
          suggested that copies of the FAA letter of December 9, 1969 as well as the
          Black & Veatch letter of February 19 be sent to all members of the Steering
          Committee.

          A tentative date for April 24 was selected for the next committee meeting.

                               APPENDIX  E
                DATA ON  INVESTIGATED SITES FOR
      A SOLID WASTE  MOUNTAIN AND  RECREATION AREA
                   IN NORTHWEST  COOK COUNTY
        WITHOUT SERIOUS CONFLICT  WITH AIR TRAFFIC
   Data are  presented for four investigated sited in northwest Cook County, plus
Revised Site 5 in Lemont Township modified for a 300-foot mountain  which
would not conflict with air  traffic.  Considerations common to  two or more
sites  are discussed  under topic headings  relating  to  site  suitability. Detailed
information peculiar to individual sites is presented  in a tabulation following
the general discussion. A general location map and maps of the individual sites
follow the tabulation.

   Also attached is  a brief discussion of the areas nearest Chicago where the
Federal Aviation Administration indicates  that a 1,000-foot  high solid waste
mountain would not conflict significantly with air traffic.

SIZE AND CONFIGURATION
   Area, width and  length limit the  permissible  height and volume of a solid
waste  mountain,  influence its  general form, and restrict design  flexibility. A
large  site  with a generous width permits a higher landfill as  well as greater
latitude in naturalizing the mountain into the surrounding landscape. To obtain
maximum height and fill capacity  on a small site, naturalization must be
sacrificed. Sites 6, 7 and 9 would permit much  greater design flexibility on a
500-foot high mountain with an average side slope  of 4 to 1 than Site 8 which
has a width of only one mile and an area of only  1,200 acres. Revised Site 5
was limited to a height of 300  feet (MSL elevation 1049) to eliminate conflict
with air traffic, and  its area was  reduced to about  1,400 acres.

   Site size and configuration were governed by  availability of large, relatively
undeveloped tracts  not bisected by  major  thoroughfares  which satisfy to a
reasonable degree the other site selection parameters discussed.

   The volume for  solid waste  deposition in a mountain  that could be con-
structed on a site is  a major factor in  evaluation of potential sites.  The attached
site maps show  a preliminary  filling plan for each site. Landfill capacity in
acre-feet  for each site was  calculated and  is shown on  the attached graph
                                  E-l

-------
together with the estimated cumulative landfill  capacity in acre-feet required
for disposal  of Cook County refuse prior  to 1995, based on the following
assumptions:

       — The disposal operation would be conducted at  one site and
          would start in 1975.
       — Between 1975  and 1985, only 50  per cent of the wastes not
          disposed of through existing incinerator plants, or plants cur-
          rently under construction, would go  to the Ski  Mountain
          disposal site.
       — After  1985,  all solid wastes not incinerated would go to the
          Ski Mountain disposal site.
       — Rock spoil from the storage chambers for the proposed deep
          tunnel system  would be delivered to the Ski Mountain dis-
          posal site  at a uniform  annual rate over a 10  year period
          starting in 1975,  and would  occupy a  total of 75,000 acre-
          feet of space in the solid waste mountain, including a 35 per
          cent swell factor.

   Intersections of each  site  capacity line  on the graph with the  curves of
cumulative required landfill space indicate the year that the site would be filled
under the assumed conditions. Completion dates are shown to range from 1990
to beyond 2000.
   Landfill capacities  of the sites  considered  herein  range from  170,000 to
280,000  acre-feet.  This compares with  a capacity of approximately 1,000,000
acre-feet estimated for a 1,000-foot  solid waste  mountain on the original  Site 5.

EXISTING STRUCTURES ON SITE
   Sites with fewer existing  structures are preferable to those having extensive
development  because  acquisition would be less costly and development  would
disrupt fewer people.

   The sites under consideration in northwest  Cook County are generally less
populated than those considered in southwest Cook County. Only Site 9 shows
any indication  of  recent  subdivision  for development. Some areas adjacent to
the other  sites, however,  are rapidly  urbanizing. Observations indicate  that
basically  all  of the  structures are of  good quality,  whereas  a considerable
number  of  the structures located  on  sites  in southwest Cook County were
substandard.

-------
   None of the sites have commercial or industrial development except  Site 9
 which has an  existing  gravel pit  operation and one radio  tower. Site 9  is the
 only site traversed by a major utility, a large gas pipeline.
   Minor roads traverse all sites. Ultimate  design for the completed landfill will
 determine  which roads would have to be  entirely eliminated and  which would
 be rerouted to serve local traffic. Only Site 6 is traversed by a major thorough-
 fare (Dundee Road).

 LAND VALUE
   Generally, land values in  northwest Cook  County  are much higher than in
 southwest  Cook County. The fact that most  of the dwelling units in the area
 are large  estates  suggests  that  current  land  value estimates of  $10,000  to
 $15,000 per acre may  be low. Because of impending  development, land acqui-
 sition will  become more costly in the future.

 ACCESSIBILITY
   Sites 7 and  8 have direct  access to the Northwest Toll way. Access to  Site 6
 is also provided  by  the  Northwest Tollway, but three  miles of  travel on
 Harrington Road is required  to  reach the  site  from the Tollway. Site 9 is two
 miles south of  the Northwest Tollway via Rohlwing Road.

   Sites 6 and  7 have rail access. However, the railroad that could serve  Site 7
 does not  traverse  the  heavily populated  areas of Cook County.  None of the
 sites have  access to water transportation  routes.  AH  of the sites  are over 40
 road miles  from the  initial stage  of the proposed deep tunnel project.
   Passenger transportation by rail would be beneficial in making the recreation
 facilities available to the maximum number of people. Only Site 6 would have
 direct access to commuter rail under  the C.A.T.S. recommended transit system.

 RELATIONSHIP TO OTHER LAND  USE
   With the exception of Site 7,  all of the investigated sites are located  within or
 partially within the  Metropolitan Sanitary District of Greater Chicago. All sites
 abut existing Forest  Preserve holdings but only Site 5  includes Forest Preserve
 lands. All  sites are in  the path of urbanization except, perhaps,  Site 6 which
does not presently show signs of impending development. Sites 7 and 8 would
                                   E-3

-------
be most compatible with the proposed NIPC Finger Concept of urban develop-
ment as both are located in a proposed  low density buffer wedge between
development corridors. Site 9 is in a proposed development corridor and would
not  be compatible  with the Finger Concept. Site 6  is in a  fringe area com-
patible with low density or open space development.

  Sites 7 and 8 contain parts of South Harrington,  Site 6 includes about 80
acres of the incorporated  area of Inverness and Site 9 includes an area within
the city limits of Schaumburg.

WATER POLLUTION POTENTIAL
  Water pollution potential of the sites was evaluated from  information con-
tained in publications of the  Illinois State Geological  Survey and discussions
with State Geological  Survey personnel at the Naperville, Illinois office. Avail-
able data indicate  that  geological  conditions  at  all of the sites are generally
favorable for solid waste disposal. The creviced dolomite aquifer which under-
lies the sites is covered  with relatively impervious glacial till,  ranging in thick-
ness from about  100 to 200 feet. Although some of the till would probably be
excavated and used  for covering the refuse, a sufficient thickness of till would
remain  to prevent  the passage of leachate  in  sufficient  quantity to cause
significant  pollution  of usable ground  water.  Leachate would  probably  be
collected, by underdrains,  and treated as additional protection of both surface
water and ground water.
  Consideration  was  not  given to investigated sites  on the   western  edge of
northwest  Cook  County because  geological reports indicate  that in this area
sand and gravel  deposits overlay the creviced dolomite. Under this condition, it
would be difficult to prevent pollution of the aquifer.

DRAINAGE
  Where possible, sites  were selected in the upper portions  of watersheds to
minimize the amount  of runoff that would need  to be diverted. Ownership of
all  drainage area  tributary  to  a  site would  be  advantageous, as this would
permit filling in a manner to facilitate drainage.

  Revised Site 5, and Sites 6,7 and 8 are considered suitable from the  standpoint
of drainage. Runoff from a large outside area which flows through Site 9 would
reduce the usable area of this site  or necessitate extensive grading  for proper
control of drainage.

-------
FOUNDATIONS
   Soil borings and other subsurface investigations will be required to determine
whether the subsurface formations will support a solid waste mountain, and to
determine  the structural design parameters of the rill.  Foundation conditions
may control  the maximum slope of solid waste fill and thereby limit the height
of fill. Subsurface investigation  will also provide further data for evaluation of
water pollution potential.
   Since  each  site is underlain by a substantial depth of glacial till bearing on
bedrock, foundation  conditions are expected to be similar for all sites except
for variations  in depth of til). Therefore, it will probably be necessary to make
subsurface  investigations of only the site or sites selected on the basis of other
factors.

OBSTRUCTION TO AIR TRAFFIC
  The Federal Aviation Administration (FAA), Chicago office, provided guide-
line elevations for structure heights at the four sites which would  not adversely
affect air traffic at O'Hare Airport. The FAA  advised that structures within the
guideline heights on the four  sites would not  interfere with traffic control
radar.

  Although appreciably higher structures could be accommodated by air traffic
in northwest  Cook County than  in southwest Cook  County, the height of a
solid waste mountain  in the  northwest  area  would be restricted  to less than
1,000 feet.  Structures over 500  feet high would constitute obstruction to small
aircraft on  VFR navigation.

MAPS AND SITE DETAILS
  Attached are a  detailed tabulation  of evaluation data for each of the five
sites, a tabulation of advantages  and disadvantages for each site, a location map,
and maps of each of the sites showing a preliminary filling plan.

REVISED SITE 5

    Advantages
           1.  Shorter haul distance than NW sites.

        NEAREST  AREAS OUTSIDE  COOK COUNTY WHERE
      A 1000-FOOT HIGH SOLID WASTE MOUNTAIN WOULD
       NOT  CONFLICT  SIGNIFICANTLY WITH AIR TRAFFIC
  Conferences were held with the Chicago Area Office of the Federal Aviation
Administration  to determine the nearest areas outside Cook County where  a
1000-foot high solid waste mountain would not conflict significantly with air
traffic. The FAA advised:

      1.  To  the north  and south of O'Hare Airport, heavy air traffic
         and existing airports virtually prohibit a 1000-foot high solid
         waste mountain.

      2.  The proposed  new Chicago Airport,  expected to be located
         southwest  of Chicago,  may  also be  a major deterrent to a
         solid waste mountain south of Cook County.

      3.  Preliminary investigation indicates three general  areas to  the
         west where a 1,000-foot mountain would apparently cause  few
         problems for air traffic. These areas, shown on  the attached
         Chicago Region map, are located:
             Northwest  in  McHenry  County  in  the  Woodstock,
             Marengo, Harvard triangle;
             West  in Kane County, approximately  15 miles west of
             Elgin; and
             Southwest in Grundy or LaSalle Counties, south of  the
             Illinois River and the Town of Seneca.

      4.  The FAA  would have to make an in-depth study  to render an
         official opinion of the  effects  on air traffic of  a  1,000-foot
         high solid waste mountain in any of these areas.

      5.  Any structure  more than 100  feet  above  the ground surface
         poses  some  obstruction to  Visual  Flight  Rules navigation.
         However,  since VFR traffic  is much lighter over the three
         suggested areas than over western Cook County, the adverse
         effect of  a 1,000-foot mountain in these areas  would be
         much  less than for the same mountain in Cook County.

  The west  and southwest areas are near  Interstate highways. The northwest
and west areas  are served by railroads. The southwest area is near  the Illinois
Waterway. Detailed investigations of transportation and other site factors would
bv required  to  ascertain the suitability of any  of the three areas for use as  a
solid waste disposal site.

                             APPENDIX F
                   DATA ON  INVESTIGATED  SITES
                       FOR A 1000-FOOT HIGH
        SOLID WASTE  MOUNTAIN AND RECREATION AREA
     NEAR COOK  COUNTY AND ALONG ILLINOIS  WATERWAY
   As instructed by  the  Steering Committee on April 24, preliminary investi-
gations  have been made of  potential  solid waste  mountain sites  along  the
Illinois Waterway in  the  vicinity of Seneca, Illinois. Data are presented for five
sites considered to have potential for construction of a  1,000-foot  high solid
waste mountain  without causing serious  hazard to air traffic. Considerations
common to the sites are discussed under topic headings relating to site suit-
ability.  Detailed  information peculiar  to individual sites  is presented in  a
tabulation following  the general discussion. A general location map and maps of
the individual sites follow the tabulation.


SIZE AND CONFIGURATION
   Investigated ski mountain sites selected for consideration outside Cook County
range in size from 6.6 to 12.1  square  miles and all are larger than the largest
site  previously  analyzed  inside  Cook  County. The open,  rural  character  of
outlying Grundy  and  LaSalle Counties facilitated selection  of potential sites
with sufficient acreage  to  permit generous  setbacks and  protective buffers
around  the sites.  In rapidly urbanizing Cook County, this amenity was less
easily accommodated. Other  advantages of larger sites are greater design flexi-
bility,  greater  fill capacity,  more latitude in  the provision of recreational
facilities and a better opportunity  to  retain existing natural features, such as
drainage areas and tree  cover.  For example,  Site 10, largest of the five sites,
would  be  most  adaptable  to staged  development, would permit  an  earlier
realization  of recreational  potential,  would  be almost completely buffered
from abuting  land  uses,  and would  permit  almost total  preservation of its
rugged  physical characteristics.

   Each  site will support a mountain with a height of at least 1,000 feet with
maximum side slopes of 4 to  1.  Generalized mountain configurations, shown on
the attached site  maps,  were developed  to roughly  estimate the fill volume
which could be supported reasonably on each site  without destroying its most
interesting  natural  assets.  These  should  not be  construed as  final  design
concepts.

                                  F-l

-------
   Estimated landfill volumes; of the sites range  from 1,093,000 to 1,858,000
acre-feet.  Considering that the landfill space requirments of Cook County are
estimated to  average about  10,000 acre-feet per year over the next  20 year
period,  life  of the sites for Cook County solid wastes appear to be in the range
of 50 to 150 years.

EXISTING LAND USE AND STRUCTURES ON  SITES
  The principal  land use  on  each of the investigated sites is agricultural. None
of the sites is heavily populated. The smallest site (No. 11) contains 19  existing
homes,  while  the largest  site (No. 10) contains  about  100. Site 10 includes a
small cemetery which  could  be rehabilitated  and retained in  the  final design
concept. None of the sites presently contain commercial  or industrial develop-
ment. Sites  11 and 13  each contain a marina which could  become an  integral
part of the proposed   recreational facilities. None of the  other sites  contain
major  nonagricultrual   land  uses.  Site 11  abuts the DuPont  Seneca  Works
(fertilizer  plant)  on the north. Site 13 abuts a proposed Commonwealth Edison
power plant on  the Illinois  River.  An 8,000 acre tract  is purportedly  being
acquired to the  south  of this site for a large cooling lake. The possibility of
obtaining  additional  fill  material from this  proposed  lake  remains  to be
investigated. Site  14 abuts Starved  Rock State Park on its north boundary.
  Two  gas  lines, two  power  lines and a microwave path  traverse Site 10.  A
powerline crosses Sites 11, 13, and 14. Site 13 is traversed by a microwave path
along its  east border.   Only   Site 10 is bisected  by a major  highway, U.S. 6,
which would require rerouting.

LAND VALUE
  Land values in Grundy and LaSa|le Counties  according to their respective
County Assessors, average about $700 per acre for good  farm land. Properties
along the Illinois  River are selling for prices ranging up to  $1,500 per acre.
Each of the investigated sites considered herein would cost less than any of the
smaller sites considered  earlier in Cook County.

ACCESSIBILITY
  Sites  10,  11 and 13 have direct access to the Illinois River while Sites 12 and
14 are approximately Vz mile  from the river bank.  Major highway access to all
the sites is via 1-80.  Highway access to each of the sites  except Site 12 passes
through an  existing town. This disadvantage could  be rectified more  easily for
Site  10 than for Sites 11,  13, and 14.
                                 F-2

-------
   Sites 10, 11, and  12 have direct rail access, while Sites 13 and  14 have rail
access within  Vt  mile  and  IVi  miles  respectively.  Site 10 has access to two
railroads:  the  Chicago, Rock  Island  and  Pacific and  the Elgin, Joliet and
Eastern. Other sites have access  only to the Chicago, Rock Island  and Pacific.

   Approximate distances of the sites from Chicago Loop are:

                  14                100                 94

LOCATION
   All investigated sites are located along the Illinois River in northeastern Illinois.
Sites 12,  13,  14 are located in  LaSalle  County. Site 11  straddles  the  LaSalle-
Grundy County Line and Site 10 straddles the Grundy-Will County  Line.

WATER POLLUTION POTENTIAL
   Water pollution potential of the sites was evaluated  from published reports
of the  Illinois Geological Survey, the State  of Illinois Department of Business
and  Economic  Development, and  discussions  with State Geological Survey
personnel at the Naperville office.

   Available information indicates that hydrogeological conditions  are generally
favorable for solid waste disposal at all of the investigated sites. Fifty to 100 feet
of relatively impervious silty clay glacial till  covers bedrock at each  of the sites.
Bedrock at Site' 10 consists  of the Maquoketa Group, a poor aquifer  composed
mainly of impervious shales  which retards vertical movement of water to lower
bedrock  aquifers.

   Bedrock at the other sites is the Carbondale formation of the Pennsylvanian
System,  a poor  aquifer consisting  mainly  of  shale with siltstone, sandstone,
limestone  and  coal.  Water  in the  Pennsylvanian System tends to  be highly
mineralized at greater depths.

-------
DRAINAGE
   Where  possible, sites  were selected in  upper portions  of watersheds to
minimize the amount  of runoff to be  diverted. Ownership of all drainage area
tributary  to a  site would  be advantageous,  as  it would permit  filling  in a
manner to  facilitate drainage. Due  to size of the sites, all  will pose  some
drainage problems.

   Drianage  of  Site 10 will  be facilitated by high interior topography which
drains in  all directions to the exterior. Sites 11  through 14 each drain large
outside areas to the river. Although more extensive grading may be required at
these sites, initial investigations indicate adequate drainage can be accomplished.
Drainage from Site  14 passes through Starved Rock State Park and will have to
be carefully controlled to prevent inconvenience to the  public.

FOUNDATIONS
   Soil borings and other subsurface investigations will be required to determine
whether subsurface  formations will support a 1,000-foot solid waste mountain
and to determine structural design parameters of the fill. Foundation conditions
may control the maximum slope of the solid  waste fill and, consequently, the
height and configuration  of the fill. Subsurface investigations will also provide
useful hydrogeological data for evaluating water pollution potential and means
for preventing or minimizing pollution.

OBSTRUCTION TO AIR TRAFFIC
  The Federal Aviation Administration (FAA), Chicago office, delineated  the
general  areas along  the  Illinois waterways where a IpOO-foot high solid waste
mountain would  conflict significantly  with  air  traffic.  Areas of conflict  are
indicated  on  the  attached  site location map.  Potential disposal sites  were
selected in areas free of such conflict-
  Any structure over  500 feet above existing ground is considered an obstruc-
tion to small aircraft  on VFR navigation.  However, the FAA indicated  that
approval is normally granted for structures erected in the public interest if they
do not consitute a serious hazard to air traffic.

  Prior to actual construction of a  1000-foot high solid waste mountain on any
of the investigated  sites, an  official notice of proposed construction  should be
filed with the FAA.

 Dear Mr. Dalton:

 Although we discussed the  proposed ski mountain site near Minooka (Site 10)
 with the Federal Aviation  Administration (FAA)  Chicago Area Office,  and
 received an unofficial opinion  that a 1000  foot high mountain at this  site
 would not  be  a significant hazard  to air traffic, we believe FAA Form  7460-1
 should be  submitted on this  site as was  done  for the proposed Lemont Site.
 Accordingly,  we have  filled  in  the appropriate  information on a copy of
 FAA  Form 7460-1 and are enclosing  this form and blank copies of it.

 The  data shown on  the form are  merely our suggestions and may be modified
 as you see fit.

 Please complete the blank  form  and submit it, together with a request  for
 an immediate  study, to:

                         Mr.  M.  L.  Kolhler,  Chief

                         Des  Plaines,  Illinois   60018

 We would appreciate receiving copies  of  all correspondence between the
 Metropolitan  Sanitary District  and the FAA  on this matter,  so that we  will
 be apprised of  the FAA findings.

                                             Very truly yours,

Mr. Frank E. Dalton

Dear Mr. Dalton:

We have completed an aeronautical review of the proposed solid waste
ski-mountain and recreation area, in accordance with the information
submitted to us in the FAA Form 7460-1, Notice of Proposed Construction
or Alteration, dated 14 July 1970.  The review was conducted within
our organization and was not circularized to aviation interests as
agreed upon during your telephone conversation with Mr. Keith Potts
of our office on 30 July 1970.

Our study disclosed that the proposed ski-mountain would have the
following effect upon present aeronautical operations and procedures:

1.  It would require that the minimum en route altitude of Federal
Airways V171, V429 and V38 be increased from 2500 feet MSL to 2700
feet MSL.

2.  It would require that the minimum obstruction clearance altitude
of Federal Airways V171, V429 and V38 be increased from 2100 feet MSL
to 2700 feet MSL.

3.  It would be located immediately adjacent to the Illinois River,
which is a prominent, readily identifiable landmark that may constitute
a regularly used Visual Flight Rules route.  As previously pointed out
in our comments concerning the proposed ski-mountain, the public has
che right of freedom of transit through the navigable airspace in
accordance with Public Law 85-726, Federal Aviation Act of 1958.  Our
procedures dictate that a proposed object would have an adverse effect
upon air navigation if it would exceed a height of 500 feet above the
surface at its site and would be  located within two statute miles of
any regularly used Visual Flight  Rules route identifiable by prominent
landmarks suitable as visual aids to air navigation.  Further study
including aeronautical circularization of the proposal to all known
interested persons would be necessary in order to determine if the
Illinois River is or is not a Visual Flight Rules route.

-------
  Therefore, we request  that at such  time as plans for  the ski-mountain
  become more definite,  that you notify us and at that  time, we will
  initiate a full aeronautical study  and issue an official airspace
  determination.

  If we may be of any further assistance or service in  this matter,
  please do not hesitate to contact us.

  Sincerely,
 'M.  L. KOEHLER

haqp of rhp formation.  A few remnants of the tnm rcnnsy ivanian (,coal Measures)
are present.  Underlying the Maquoketa is the Galena-Platteville dolomite which is
in turn underlain by the St. Peter sandstone.

          The glacial drift overlying the bedrock is variable in thickness and
character.   In the northeastern part of the site between Minooka and Channahon the
drift is relatively thin, less than 50 feet thick; in the DuPage River Valley
gravel is present but the rest of the area is mostly clayey till.  In the Aux
Sable Creek lowland sandy deposits are also found near the surface, but are under-
lain by rather thick, clayey till.  In a large part of the site  the glacial drift
is 100 to 150 feet thick.  VJjjere t^iis thick, the upper 80 to 100 feet is clayey
till which is underlain by permeable sand and gravel.  Sometimes more than one
gravel zont is present.

Mr. C. E. Clark, Chief - 2                                         August 31, 1970
          Water supplies in the area are mostly obtained from drilled wells finished
in the bedrock, although undoubtedly a number of old dug wells are present in the
area which are still in use.  The most productive horizon is the St. Peter sandstone,
encountered at an average depth of about 500 feet.  However, both the Maquoketa and
Galena-Platteville are productive and most domestic supplies are finished in these
formations at 150 to 130 feet.  The gravel in the glacial drift probably is also
highly productive where present.  However, most wells are flhished in the underlying
rock because of ease of well construction (and therefore lower costs); some wells
finished in the rock immediately below the gravel undoubtedly draw water from the
gravel also.

          We have no records of a public water supply at Channahon; apparently water
is obtained from individual wells.  Minooka obtains water from wells 640 feet deep;
the St. Peter sandstone is the principal producing zone, although the holes are open
to the shallower dolomites.  The drift at this site is only 40 to 45 feet thick.
Water levels in the wells in this area average about 80 to 100 feet below land sur-
face.

          It is impossible to give an overall opinion of the site as a landfill pro-
ject of the dimensions of this project.  Obviously a considerable amount of drilling
would have to be done to better evaluate the thickness and character of the glacial
drift.  From the available data it appears that the area is, in general, favorable
as a landfill site.  My main concern would be for the northeast area where the
drift appears to be thin and deep trenching could strip most, if not all, the
protection from underlying dolomite aquifers, which then could transmit pollutants
large distances ( dolomites, like limestones, transmit water through fractures
which afford little or no filtering).  Also the shallow sand in the Aux Sable Creek
area could possible be affected.  There is ample water available from the deep
St. Peter sandstone to provide an alternate supply should it be necessary to provide
for one.

          Considerable care by an experienced well plugging company would have to be
taken to plug all wells penetrating the aquifer in the area as they make a direct
connection between the surface and aquifers.  Location of all wells may be somewhat
difficult and operation of the landfill may reveal wells not located during the
original plugging operations, and appropriate care must be taken to plug these when
found.

 Gentlemen:
     As requested, we have prepared a cost estimate based on relocating our
three pipelines to the perimeter of the proposed disposal site south of the
town of Minooka.

     We have determined that the route proposed in your original correspondence
is generally acceptable to us and was used in preparing the estimate.  In utili-
zing this routing, approximately 3.7 miles each of existing three lines would be
replaced with U.75 miles of relocated lines.

     Existing facilities consist of one 30-inch and two 36-inch pipelines.  Be-
cause of the increased length of the relocated lines compared with the existing
facilities, an increased pressure drop of h psi will result if pipe of the same
diameter is used.  To eliminate this pressure drop and the resulting loss of
capacity, the replacement pipe must consist of three 36-inch lines.

     In preparing the estimate, it has been assumed that the existing lines will
be abandoned in place.  If it is determined at the time of relocation that it
would be economical to salvage these lines, this would then be done.  This aspect
cannot be determined at this time.

     Also, it has been assumed that we will not acquire new right-of-way but will
utilize Sanitary District right-of-way on the periphery of the site.

     Based on three 36-inch lines, each 4.75 miles in length we have estimated
a total cost of $3,580,000 or approximately $48 per lineal foot.  This figure
assumes 1971 construction and material costs.

     Data on these new facilities are as follows:

Dear Mr. Klrkpatrick:

          This is to confirm my telephone conversation with
Mr. Tancy regarding an estimate of costs we could incur  in
relocating facilities to clear the Metropolitan Sanitary
District of Greater Chicago-Ski Mountain Project  5180, Site
No. 10.  I gave Mr. Yancy a figure of $5,000,000  for the cost
of relocating existing and planned facilities  through the area
exclusive of any alternate right-of-way costs.

          I superimposed on your attached print the location
of our rlght§-of-wmy, together with a legend indicating  the
number of existing and planned transmission lines and their
voltage through the various segments.   The planned lines are
those which are currently being engineered for early construc-
tion.

          The estimate is contingent on our being able to install
the 765-KV tower line along an alternate route as indicated by
dashed red line.  If this line had to be rerouted in a manner
involving  more angles or, if it had to be rerouted outside the
area completely, the estimate would be substantially increased.

          If you desire any further information,  please  let
me know.

                                    Yours truly,
                                   A. R. Heidecke

Dear Sir:

This is in response to your request regarding the solid waste disposal
study near Channahon, Illinois (Project No. 5180).  The location and
height of this waste deposit would interfere with our microwave and
other outside plant facilities.

We have estimated the cost of relocation and adjusting our facilities
based on current cost at $460,000.

                                               Very truly yours,

                          SOLID V/ASTE DISPOSAL CONCEPT
                              COOK COUNTY,  ILLINOIS

     Gentlemen:

            This letter confirms verbal presentations made to you and your

     engineers on June 2k.  We have, at your request, identified probable

     geologic subsurface conditions using reference information you made

     available plus our own library resources.  A list of the Information

     available is attached in the bibliography.  The object of this review

     was to provide the basis for preliminary findings relating these con-

     ditions to foundation performance of the proposed construction.  The

     scope of all work is preliminary.  The data available for review has

     been of a geologic character.  Within this site, denoted Site 10, no

     borings have been performed and no laboratory test results of an engi-

     neering nature are available.  The only wells for which data are avail-

     able have been extended into bedrock; logs in the surficial deposits

     are not aval table.

            To provide perspective to our findings the scope of proposed

     construction Is described.  The general geologic setting, with possible

variations and expected  important  characteristics,  is  described and



subsequently  the  findings  and  recommendations  are  presented.








PROPOSED CONSTRUCTION



       Proposed construction envisions  an  ultimate  1000  foot  maximum




sanitary landfill constructed  with average outboard slopes  of k (hori-




zontal) to I  (vertical)  covering portions  of  twelve sections, ten of



which are in  Grundy County and two in adjacent  east Will  County.  The




site is generally bounded  by the DuPage River  and  the  Des Plains River



on the east and the area of confluence  with the Kankakee  River to the



south.  (Below these  watersheds it is  known  as the Illinois  River.)



As generally  visualized,the soil material  present within  this area



would be used as cover material for the landfill  layers.   Assuming



a 10 percent  proportion  of soil to total mass,  it  is estimated that



some 50 feet of excavation throughout the  area  of  landfill  mass would



be necessary.  To provide  a base for permanent  construction,a relatively



non-yielding central core  area has  been proposed.   A required width



of 50 feet at the crest  is necessary.   Phased  construction  is desired.



During construction portions of the site would  be used desirably for



recreation and ultimately  the  area  would be a  ski mountain  site.  The




time to ultimate development is estimated  at one hundred  years.








GEOLOGIC SETTING




       Our review of the available  geologic literature suggests this



site is underlain by bedrock at depths  of  50 to 100 feet.   The uppermost
                               G-13

-------
K-70-5                                                       Page  3






bedrock unit is  likely shale of the Maquoketa formation.  Outcrops




of overlying dolotnitlc rocks are present short distances  to  the east



particularly along the Des Plains River.  The shale beds  of  this  unit



are low pervious, generally not productive of groundwater, although




included dolomitic beds are sometimes  low yield aquifers.  The bedrock



surface is overlain by glacial deposits of which  the most prominent




feature is the Minooka moraine.  This  is an  interglacial  terminal



moraine oriented north-south.  It terminates at the confluence of the



rivers bounding  this site.  This type  glacial feature  is  normally composed



of a large variety of grain sized materials  including  everything  from



boulders down to and including clay till.  As mapped,  this feature



extends areally over the central portion estimated at  approximately



two-thirds of the construction area.   It was constructed  by  the glacial




Ice sheet at a point in Its recession  when the advancing  ice and  melting



resulted in a virtual standstill of the ice advance.   This resulted



in the production of accumulation of glacial debris in which the  local



production and distribution of melt water determined the  character



of the deposits.  As mapped by Thornburn the surface materials are



described as "dark colored moderately  slowly permeable soils from thin



loess on silty clay loam till."  Figure 6 of groundwater  report number



1  shows a sand content in the Minooka  moraine.  Bergstrom, in his "Disposal



of Wastes" paper, quotes previous writers as saying, "the piezometer



response to precipitation at various depths  in glacial till  suggests



that some groundwater movement takes place rather quickly through joints



rather than through intergranular openings."  All indications considered,

-------
K-70-5                                                       Page *





we anticipate  the Mlnooka moraine  is  an  indurated  mass  of variable



deposits, predominantly a sllty  clay  till  but  including,  very likely,




important quantities of granular materials In  some positions with unknown



configurations.



       Subsequent to deposition  of  the Mlnooka moraine,  the  area was



inundated to a maximum  level  of  about elevation 6^0 by  fresh water.



The water level  fluctuated  but was  held  in the area by  a natural dam



south and west of the area  under consideration.  This  inundation is



known as the Lake Wauponsee occurrence.  Deposits  of Lake Wauponsee,



as described in  the  literature are  thin, 4 to  6 feet being the only



stated reference.  These materials  are mapped  by Thornburn as "predominantly



dark colored moderately permeable  from medium  .to fine  textured soils."




An old agricultural soils publication on Grundy County  also  describes



organic accumulations within  the mass of glacial drift.



       In a time sequence between  the Minooka  formation  and  Lake Wauponsee,



the terminal moraine was also subjected to important quantities  of



melt water known as the Kankakee torrent.   Deposits from the torrent



would logically be granular and  highly pervious.



       We interpret these data as suggesting that  overlying  the  moraina)



tilt soils a variety of materials which are likely of finer  texture



and lower strength will occur with  from limited  to possibly  important




but presently undetermined  maximum  thicknesses.  It would not surprise



this writer if these thicknesses increased  to  from 20 to 30  feet.  These



deposits, where they occur, undoubtedly overlap  the basal  portion of




the Hinooka moraine and envelop  the  irregular configuration of  the
                               G-15

-------
K-70-5                                                      Page 5






moraine formed by erosion of that feature during the important inter-



glacial periods which occurred between its deposition and1 the Lake



Wauponsee time.  Whereas the moralnal materials because of their deposi-



tion and character are precompressed and likely relatively high strength.



The overlying water-worked deposits will be less strong, generally



more pervious with the potential for highly pervious layers or lenticu-



lar materials within the sediments.  Because the permeability of the



morainal materials is small and controlled by joint configurations,



surface run-in more than likely moves to the regional drainage features



at the interface of the glacial till and the waterlaid materials.   It



also is likely channeled and controlled by flow in the most pervious



materials, if they exist in continuous ffeatures leading towards the




major drainage pattern.








SITE 10



Preliminary Conclusions





1.  The site is underlain partially by glacial moraine and, partially,



       by a lacustrine and/or outwash over till profile.  Areal extent



       of the water-worked materials is unknown but it will be limited



       to edges.  Their thickness may be thin with local variations.




2.  Contact of ti11-lacustrlne units may be sloping; it may also be



       a contact on which surface in-flow moves to the drainage system.



3.  Softer, local accumulations of organic contaminated soils pro-




       bably occur sporadically at existing grade.

 4.  Strength of  the post-glacial or water-laid materials  is  likely



        less, and probably considerably  less,  than moral pa 1 materials.



 5.  Probable cross-sections  through the mass  are as  shown on attached



        figures;  proposed fills are shown  In proper scale.



 6.  Compacted soil properties will vary in a  wide range, as  would be



        Indicated by expected variations In material  types -  sands to



        medium plastic clays  and clay-gravel-boulder  mixtures.



 7-  Local changes  in soil water content and perched  water tables  are



        likely.  Amount of pumping in excavations will vary greatly



       with



               location,




               depth of contact, and



               season.




 8.  The mechanisms of soil slope failure  considered  possible include:



       A. Base failure through lacustrine soils;



       B. Wedge failure on:



               1 - Plane inclined on moraine;



               2 - Soft layer in natural  profile;



               3 - Plane built into fill.



9.  It  is impossible to analyse potential  to  failure without soil



       strengths, but the "A" type failure at edges  of mass  is judged



       to be likely in some areas.  If it occurred it could  be of



       large magnitude.




 10. No data on strength of constructed fills  other than experience



       with existing land fills.   This evidence does not cover the
                                G-17

-------
K-70-5                                                      Page 7






       range of stresses expected.  The data may not be indicative



       for high range stresses, if envelopes are not linear, and we



       would expect they are not  linear.



II. The over-all stability of the fill mass could be marginal - we




       actually expect that it will be marginal in some locations.




       The failure mechanism may be by circular base failure, first,



       with over-all wedge movement later as the fill reaches maximum




       proportions.



12. A very complex stress distribution will occur adjacent to a semi-



       rigid mass placed within the waste fill.  The stress distribu-



       tion will likely change with time as well as applied stress.



13. A 50 foot wide soil wall, for "Spine", is probably not stable  if



       constructed 1000 feet high within the fill.  With limited analysis



       we do not believe a base width of less than 250 feet can be



       accommodated without risking a failure controlled by geometric



       considerations rather than by shear strength.



1*». Temperature conditions are not definable with present data.  Logically



       we believe construction control will be key to controlling  the



       temperature production.  This will require knowledge of heat




       production at thIs site with these environmental conditions.








RECOMMENDATIONS



       We recommend that:



1.  A preliminary study to identify ranges in types of soil materials,



       area! extent and depth to top of moraine, and depth to ground-



       water.

K-70-5                                                      Page 8


2.  Work be commenced in edge areas as berm construction will  likely

       be desirable for maximum stability.  The extent and  limitations

       of this procedure should be studied.

3.  The "Spine" must be located directly on till at all locations.  The

       geometry is such that a 50 foot base width will not  be  suffi-

       cient.  Our estimates would suggest 250 feet at base might be

       required as minimum to eliminate the "geometry problem."  Although

       very complex, the expected stress system makes this  a "real"

       problem.  It must be studied now before any construction of

       "Spine" areas begin.  (See Figure).

A.  Prior to fixing the design objectives you find and program 50 foot

       average excavation in order to make a mountain, 1000 feet high,

       feasible.   This criteria assumes 10 percent cover and usable

       materials  (clay type soils) obtainable above free water levels.

5.  Monitoring be included as necessary elements in the design pro-

       cedure.  Several  features of the construction suggest no reason-

       able alternatives are available to identifying prototype perfor-

       mance.   I terns to be measured are:

               A.  Relative settlement

               B.  Lateral  movement

               C.  Stresses -

                    Vertical

6.  Construction of the "Ski Mountain" site be considered carefully
       in a feasibility study to consider magnitudes of problems asso-
       ciated with subsurface foundation conditions.  The scope of
       studies should be defined after preliminary borings provide a
       correct picture of subsurface conditions.
       The opportunity to consider the foundation and soil mechanics
aspects of this unique project has been appreciated.  We have attempted
to communicate the results of our review and analyses without fully
describing mechanistic considerations and background.  If brevity
causes problems we wi11  be happy to meet with you, or your clients,
and discuss the areas  of concern.  Be assured of our continuing interest
to serve you as this project advances.

     ATTENTION: Mr. F. E. Kirkpatrick

     Gentlemen:

          This is in reply to your letters of September 25  and October  30,
     1970,  referring to a thousand foot high solid waste mountain  to be lo-
     cated in  Grundy and Will Counties.

         We have considered the information which you have submitted,  and
     have given considerable thought to the feasibility of  such  a  project
     with regard to environmental protection.  We have also obtained a  site
     survey report from the Illinois State Geological Survey for the area
     outlined  in your correspondence.  It is noted that the Survey Report
     was in considerable disagreement with the information  contained in your
     correspondence regarding the bedrock and ground water  conditions in the
     proposed  area.

          In view of the foregoing, it is strongly recommended that you ar-
     range  for a conference between responsible members of  your  staff and this
     Agency with regard to the project prior to the completion of  your  feasi-
     bility report.  I will arrange for such a conference and include represen-
     tatives of the Bureau of Water Pollution Control if you so  desire.

                                       Very truly yours,
                                       C. E. Clark,  Chief
                                       Bureau of Land Pollution  Control

   Mr. C. E. Clark, Chief

   Dear Mr. Clark:

   Thank you for the opportunity afforded Mr. Weiner and myself to discuss
   with you, Mr. Palmquist, Mr. Morton and Mr. Busch the study our firm is
   conducting for the Metropolitan Sanitary District of Greater Chicago.
   The study is to determine the feasibility of disposing of the solid
   wastes of Cook County by constructing a mountain that would be used for
   skiing and other outdoor recreation.  This letter will provide a brief
   record of our discussions in your office on January 18, 1971.

   As indicated in previous correspondence to you, the study is being based
   on a 7000-acre solid waste mountain site in Grundy and Will counties
   south of Minooka.

   You gave us copies of a letter report by the State Geological Survey
   regarding hydrogeologic conditions of this site, dated August 31, 1970.
   You also gave us copies of the Environmental Protection Act - 1970 and
   of other State rules and regulations pertaining to solid wastes.

   As discussed, we have revised the filling concept outlined in our letter
   of September 25, 1970.  We now propose to exclude organic waste from the
   solid waste mountain to the maximum practical extent.  This change was
   made because we see no way of assuring the structural stability of a
   1000 foot high fill composed largely of organic matter.  The fill would
   be made with relatively stable materials such as glass, metals, ceramics,
   incinerator residue, noncombustible demolition debris, broken pavement,
   concrete, rock from the proposed MSDGC Deep Tunnel project, and wastes
   of a similar nature.

   Organic materials would be disposed of by a combination of other methods,
   including:   recycling, incineration, and returning to agriculture land as
   compost or as shredded material which would be worked into the soil to
   compost naturally.

BLACK a  VEATCH
           Mr. C. E. Clark, Chief               - 2 -              January 20, 1971
           We believe the 50 to 100 feet of glacial till and lake deposits on the
           proposed solid waste mountain site would protect the bedrock aquifers
           from pollution by landfill leaching.  However, a thorough subsurface
           investigation should be made prior to final design to further define
           subsurface conditions, suitability of the site, and provisions which
           may be required to protect ground water.

           Our report will recommend that an underdrain system be provided around
           the periphery of the solid waste mountain to collect leachate, and that
           leachate be  treated by a modification of the activated sludge process
           in oxidation ditches.  After final settling and chlorination, the ef-
           fluent would be used to irrigate grass or crops on the site or discharged
           to the Des Plaines or Illinois river.  Surface runoff from the fill site
           would flow through sedimentation ponds prior to discharge to the rivers.

           You advised  that:

           1.  Rules and regulations to be issued soon will require daily covering
               of incinerator residue, power plant ash, inorganics removed from
               combined refuse, and any other wastes containing organic matter.

           2.  Rock, concrete, brick, earth and similar natural inorganic materials
               will not require daily cover.

           3.  There is no prohibition on land disposal of organic matter if no
               pollution results.

           4.  A special permit is required for placing any sludges in sanitary
               landfills and the general policy is to exclude sludges if there
               is a possibility of water pollution.

           5.  A test hole to bedrock would be required for each 5 acres of a
               proposed landfill site.  Permanent inspection and check wells
               would be required to monitor leachate.  All existing wells on the
               site would have to be located and plugged.

           6.  Runoff and treated leachate from the solid waste mountain site should
               go to the Des Plaines or Illinois rivers and be excluded from the
               DuPage River and AuxSable Creek.  Secondary treatment would be
               required for leachate discharged to the Des Plaines or Illinois rivers,

           7.  Your are opposed to the concept of constructing solid waste hills
               or mountains.

           8.  At this  time, you are opposed to a solid waste mountain at the pro-
               posed site near Minooka because of the possibility of water pollution
               and because you believe the coal strip mines in Illinois are more
               logical  areas for solid waste disposal.

            As  discussed, we plan to complete  the feasibility study  for the  solid
            waste mountain  based on the site near Minooka  and the  requirements  of
            the Environmental Protection Agency.

            Thank you  again for the opportunity  to discuss this  project,  for the
            information  furnished,  and for your  candor  regarding the ski-mountain
            concept.   All of this will assist  in evaluating the  feasibility  of
            the project.

           COSTING OF  TRANSPORTATION  SYSTEMS
  Costs  of  transportation  systems  for  delivering solid  wastes to  the Ski
Mountain were estimated on the following basis:
         Level of costs  prevailing in 1970

         Public ownership,  operation and maintenance of:
              Collection vehicles
              Transfer stations
              Processing equipment
              Stationary compaction equipment
              Containers
              Highway transfer vehicles
              Barges
              Railroad equipment
              Pipelines
              Disposal site  equipment

         Contracts with private firms to  own, operate, and maintain  tugs
         for towing barges  and trackage  for movement of railroad  cars,
         and to operate all railroad equipment

         Illinois State size and  weight  limitations for highway vehicles

         Interest rate of 6  per  cent  for capital

         Amortization of publicly  owned facilities with equal annual
         payments of principal  and interest  over a normal economic  life:
              Transfer stations                      20 years

DIRECT HAUL

In Compactor Trucks
  Figures H-l, H-2, and H-3 are curves  of the estimated average ton-mile costs
for  transporting refuse  in  20,  25, and  30 cubic yard compactor type  refuse
collection trucks at average travel speeds ranging from 10 to 50 mph and for 1,
2, and 3 man crews.  The curves  are for  pay  loads based on a compacted refuse
density  of 500 pounds  per cubic yard of rated vehicle capacity. Costs  for the
other pay loads are approximately inversely proportional to pay load.

  The curves cover off-route  hauling costs and are  not applicable to  actual
collection operations. Estimates were premised on one 8 hour shift, 5 days per
week, and  include an allowance  of one  hour of unproductive time per day for
startup, refueling, crew breaktime and other lost time.

  Major cost factors for the curves are  summarized in Table H-l. Hourly fixed
costs for vehicles were  based on amortizing  the  initial vehicle cost plus 10 per
cent for spares over 5 years for  the chassis and  10  years for the packer body.
Variable vehicle costs include fuel, oil, grease, tires, servicing and repairs. Labor
costs were based on City of Chicago pay scales, plus approximately 26 per cent
employee fringe benefits, including holidays, vacation, sick leave, hospitalization
insurance, Social Security tax, Workmen's Compensation and pension.

  Dumping costs were  estimated to be equivalent to the cost  of the crew and
the truck traveling at 20 mph  for 10 minutes.

 Use of the curves for estimating hauling costs is illustrated by the following example.
         Given:
              30 cubic yard collection truck
               1 man crew
              10 miles travel on city streets at 15 mph
              30 miles travel on freeway at 40 mph

         Find:
              Hauling costs for pay load of 7.5 tons and 5.0 tons

         Solution:
              Cost for 7.5 ton  pay load (Figure H-3)
                   10 miles x $0.24/ton-mile
                   30 miles x $0.12/ton-mile
                   Dumping
             Cost for 5.0 ton pay load

                   $6.32/ton x 7.5/5.0
= $2.40/ton
= $3.60/ton
= $0.32/ton

  $6.32/ton
= $9.48/ton

In Self-Dumping Trucks and Semitrailers

   Figures H-4 through H-7 are curves of the estimated average unit costs for
transporting solid  wastes  in  self-dumping vehicles ranging in capacity from 5 to
60 cubic  yards. Except for pay load, the curves were calculated on the same
basis  as the  curves  for compactor  type  trucks  using  an estimated  5-year life.
Major cost factors for the curves are summarized in Table H-2.

   Figure  H-8  shows  a basis  for  estimating  the cost of  hauling  incinerator
residue  in 10-cubic yard  dump trucks and 33-cubic  yard  self-dumping semi-
trailers.  Quenched  residue weighs  about  1,000  pounds per  cubic  yard.
Figure H-8 is based on a 3-shift per day hauling operation.

   Use of the curves on Figure  H-8 to estimate the  per ton  cost  of hauling
incinerator residue to specific disposal sites is as follows:

      1.  From  a  map, determine the approximate distance in miles of
          travel  at various speeds for a  tractor and semitrailer between
          the  incinerator plant and disposal site.  Also determine total
          one-way miles.

      2.  From  data  in (1),  estimate  one-way travel  time  between
          incinerator plant and disposal site.

TRANSFER VIA HIGHWAY SEMITRAILER

Unprocessed Refuse
  Table  H-3  shows the  estimated  initial cost and annual  cost  of a transfer
station  designed to  handle 1,000  tons per  day of  unprocessed  residential,
commercial, and industrial refuse.

  Per  ton costs for the elements  of transfer are shown  by the  curves  on
Figure H-9.  Curve A shows estimated variable costs  consisting principally of
fuel, oil,  tires, servicing,  and repairs.  Curve B shows  estimated fixed costs of
hauling consisting  principally of  driver costs, insurance,  and amortization of
investment in tractors and  semitrailers.  Curve C shows the  estimated cost for
owning and operating  the transfer station. Hauling costs were estimated on the
following premises:

      1.   Hauling three 8-hour shifts per day.
      2.   Capacity  to handle peak daily quantities  130 per  cent  of
          design average daily quantities.
      3.   Average trailer pay load of 16 tons.
      4.   Transportation equipment  to handle peak load of  1,300 tons
          per day:
                                   Trips per 8-Hour Shift

                       Trailers          73       59

      5.  Initial cost  of $21,000 for each tractor and $13,000 for each
          trailer.
      6.  Amortization of  tractors in  400,000  miles  and trailers in
          200,000 miles.
      7.  Driver  cost  of  $12,300  per year including employee  fringe
          benefits but excluding overtime.

   Use of the curves to estimate  the per ton cost of transferring and hauling to
specific disposal sites  is as follows:
      1.  From a map, determine the approximate distance in miles of
          travel  at various speeds for a tractor and semitrailer between
                                 H-fi

          the  transfer station  and disposal  site.  Also determine  total
          one-way miles.

      2.  From  data  in  (1),  estimate  one-way  travel  time between
          transfer station and disposal site.

      3.  With this  one-way travel  time, determine from  Curve B the
          number  of round trips  a  tractor can make per 8-hour shift.
          Project the "trips/shift" line horizontally to the left  margin
          and  read the fixed cost of  hauling.

      4.  Determine the  variable  hauling  cost  from  Curve A for the
          total one-way miles.

      5.  With the annual tonnage to  be transferred per  1,000 tons per
          day  of station capacity, determine from Curve C the transfer
          station cost.

      6.  Add the per ton costs determined from (3), (4)., and (5).

  For example,  assuming transfer of 300,000 tons annually from  a  1,000 ton
per day station  and  one-way travel of 10 miles at 15 mph and 30 miles at 40
mph, the  cost  of transfer is estimated as  follows:

          One-way travel:

              10 miles x 4  minutes/mile =               40 minutes
              30 miles x 1.5 minutes/mile =               45 minutes

              40 miles                                   85 minutes

          Round trips per shift (Curve  B) =                           2
          Hauling fixed cost (Curve B) =                     $2.95/ton
          Hauling variable cost  (Curve A) =                   $1.05/ton
          Transfer station cost  (Curve C) =                   $1.90/ton

          Total                                             $5.90/ton


Baled Refuse

  Table H-4 shows the estimated initial cost and annual cost of a 1,000 ton per
day  transfer and baling station handling residential, commercial, and industrial
refuse.
                                 H-8

-------
   The curves on Figure H-10 show  the elements of cost for baling and transfer
of baled refuse by semitrailer. Hauling costs on the curves are premised on the
following:
      1.  Hauling  three 8-hour shifts per day.
      2.  Capacity to  handle  peak daily quantities  130  per  cent of
         design average daily quantities.
      3.  Average  pay load of 25 tons due to  low weight of trailer.
      4.  Transportation equipment to handle  load  of 1,300 tons per
         day:
                                      Trips per 8-Hour Shift
                                         One      Two

                     Tractors             18         9
                     Trailers              20        10

      5.  Initial cost of $21,000 per tractor and $5,000 per trailer.
      6.  Amortization of  tractors in 400,000  miles and  trailers in
         200,000 miles.
      7.  Driver cost  of  $12,300  per year including employee  fringe
         benefits  but excluding overtime.

   Use of the curves for  estimating transfer  and hauling cost  is the  same as
explained previously for transfer of unprocessed refuse in van type semitrailers.
For example, assuming transfer of 300,000 tons annually from a 1,000 ton per
day station and  one-way travel of 10 miles at 15 mph and 30 miles  at 40 mph,
the cost is estimated as follows:

         One-way travel:
              10 miles x 4   minutes/mile =             40 minutes
              30 miles x  1.5 minutes/mile =             45 minutes
              40 miles                                 85 minutes
         Round trips per  shift (Curve  B) =                        2
         Hauling fixed cost (Curve B) =                  $1.60/ton
         Hauling variable  cost (Curve A) =                $0.65/ton
         Transfer  station cost (Curve C) =                $4.40/ton

         Total                                          $6.65/ton

Shredded and Separated Refuse

     Table H-5 shows the estimated initial cost and annual cost for a 1,000 ton
per day  transfer station designed to receive and shred residential,  commercial,
and  industrial refuse and  to  separate  the  shredded material  into  organic  and
inorganic fractions.

     The  curves  on  Figure  H-l 1  show  the elements of costs for shredding,
separating and transfer  of separated refuse by semitrailer. Separate haul cost
curves are shown  for  organic  and inorganic materials because the latter are
more dense and  will permit  larger pay loads. Hauling costs on the curves are
premised on the following:

      1.   Hauling three 8-hour shifts per day.

      2.   Capacity  to  handle peak  daily  quantities 130 per cent  of
          design average daily quantities.

      3.   Average pay  load  of 16 tons  for organics and 20 tons for
          inorganics.

      4.   Transportation equipment to  handle 1,300 tons per day:
                                      Trips per 8-Hour Shift

      5.   Initial cost of $21,000 for tractors and $13,000  for trailers.

      6.   Amortization  of tractors in 400,000  miles  and  trailers  in
          200,000 miles.

      7.   Driver  cost of $12,300  per year including employee fringe
          benefits but excluding overtime.

TRANSFER VIA BARGE

Rock
   Table H-6 shows the estimated initial  capital  investment exclusive of tugs,
annual capital  and operating  costs,  and average  unit costs for barge transpor-
tation of deep tunnel rock to the proposed Ski Mountain site. The analysis was
premised on all rock  being sized to  a maximum  of 8 inches and  loaded on the
barges by others. The  estimates were based on transporting 20,000,000 tons of
rock per year from three barge loading stations located near the three principal
storm  water storage  facilities proposed for  the  Deep  Tunnel  system.  Costs
include transferring Northside  rock from small  barges  to standard  barges,
unloading all  rock from  barges and  hauling in  100-ton trucks to the final
disposal area.
   The cost  of transporting ash by barge from power plants in Cook County to
the Ski Mountain  was estimated  on  the basis of providing 5 loading docks, one
unloading dock, 10 barges, one crane, and one 100-ton  truck for hauling from
the unloading dock to the fill area. The cost of loading ash on barges would be
borne by the  customer and was not included  in  the estimate. Table H-7 shows
the estimated  initial capital investment exclusive of tugs, the annual capital and
operating costs, and the average unit cost  for barge transportation  of 500,000
tons of ash annually.


Incinerator Residue
   The cost  of transporting  incinerator  residue by  barge from  incinerator
plants  in  Cook County to  the Ski Mountain was  estimated on the basis of
providing  3 barge  loading docks, one unloading  dock, 8 barges, one  crane,
and one  100-ton truck for  hauling  from  the unloading dock  to the fill area.
The  cost of  delivering  residue  from  incinerator  plants to barge docks was
not included.

Baled Refuse
  Table H-9 shows the estimated initial capital investment exclusive of tugs,
annual  capital  and  operating  costs, and  average  per  ton  cost  for  barge
transportation of baled refuse to the proposed  Ski Mountain including baling,
loading on barges,  unloading from  barges,  and hauling to the final disposal
area.  The  estimates are based on the projected 1975  quantity  of residential,
commercial,  and  industrial  refuse which might be delivered economically to
barge transfer stations.

Containerized Refuse
  Table H-10  shows  the estimated  initial capital investment, annual capital
and  operating costs,  and  average  per ton  cost for barge transportation of

TRANSFER VIA RAILROADS
   A report prepared jointly by three Chicago  area railroads on the feasibility
and  cost  of rail transportation  of solid waste from Cook  County to the Ski
Mountain site  is presented in  Appendix I.  The railroad companies'  estimates
cover  only rail- transportation  and  do  not  include the  cost  of  receiving,
processing and loading solid wastes into  rail  cars, or the cost  of unloading
and  delivering  material  to the  landfill  from  the  rail   siding at  the  Ski
Mountain site.
   A second report,  prepared  by  the  Elgin, Joliet & Eastern Railway Com-
pany,  also included in Appendix I, presents a plan and estimate of cost for
                                 H-20

-------
receiving, processing,  transporting  by rail, and  placing deep  tunnel rock in
the  Ski Mountain. The  cost  of land for receiving,  processing and loading
facilities must  be added to the railroad company estimates.
   Table H-12  presents  the estimated  costs for  receiving, processing,  loading,
transporting  by  rail,  and delivering  solid wastes  to the fill  area  of the Ski
Mountain  based  on  the  railroad  companies'  estimates  of  the  rail  trans-
portation cost.  The estimates are premised on ownership  by  the  solid  waste
management agency of all  facilities except the railroad companies' trackage
on existing  ROW,  and  upon the railroads operating and  maintaining all rail
transportation  facilities, with the solid  waste management agency operating
and  maintaining  all other  facilities.

Residential, Commercial and
Industrial Refuse and Demolition Debris
   Columns 1,  2  and  3 of Table H-12 show  the estimated capital  investment
exclusive of  railroad  trackage  on  existing   ROW,  the annual  capital  and
operating costs,  and the  average costs per ton  for  rail transportation to the
Ski  Mountain  of baled,  containerized,  and  shredded-separated-containerized
residential,  commercial  and  industrial   refuse  and  combustible  demolition
debris.  The  costs, based on projected  1975  quantities, include  receiving
refuse at the twelve potential transfer stations indicated on Figure  IV-3, process-
ing,   loading onto rail cars, transporting by rail,  unloading  from rail  cars, and
delivering to the final placement  area.
   Bales  would be  hauled on open  cars but would  be covered  to prevent
blowing and littering.  Unbaled materials would be hauled in enclosed con-
tainers  to  achieve increased  density and to  provide  sanitary and litter-free
transportation,  unloading,  and conveyance to  the  final placement  area.  Baled
refuse and containers would  be  unloaded from  rail  cars by crane  and hauled
to the placement  area in large off-highway vehicles.

Incinerator Residue
   Column 4  of Table H-12 shows  the  estimated capital investment  exclusive
of railroad trackage on  existing ROW, the annual capital and  operating  costs,
and  the average  cost  per  ton for rail transportation to the Ski Mountain of
containerized incinerator residue. The costs are  based on receiving residue at
four of the twelve  transfer stations proposed  for residential, commercial,  and
                                 H-21

-------
industrial  refuse, loading into  containers on rail cars, transporting by rail in
trains with  other  solid wastes, unloading from rail cars, and delivering to the
final placement  area. The estimates  include  40 railroad cars, 200 containers,
one  crane, and  one  100-ton  off-highway truck  for  unloading  and emptying
containers at the  Ski Mountain. The cost of delivering residue  from incinera-
tor plants to the transfer stations is  not included.

Power  Plant Ash
  Columns  of  Table H-12 shows the estimated capital investment  exclusive
of railroad  trackage on existing ROW, the  annual capital and operating costs,
and  the average cost per ton  for  rail transportation to the Ski Mountain of
power  plant ash.  The costs are based on providing three receiving stations to
which  power plant ash  would be  delivered and  loaded  into  railroad cars by
others. Ash would be hauled  to  the Ski  Mountain in trains  with other solid
wastes  where it  would be  dumped into  large  off-highway  vehicles  and
conveyed  to the  final disposal  area. The cost  of delivering ash to transfer
stations and loading onto rail cars is not included.

Rock
  Column 6  of Table  H-12  shows   the estimated  initial capital investment
exclusive of railroad  trackage  on existing ROW, annual capital and operating
costs,  and  average cost per ton  for transportation  by rail of Deep Tunnel
rock to the Ski Mountain. The  analysis  was premised on  providing three rail
loading stations  located near the  three principal  storm  water  storage facilities
proposed  for  the  Deep Tunnel  system.  The transporatation  system would
handle 20,000,000 tons of rock per year in essentially  the manner described
in the railroad  company  report, except that  the  rock  would  be sized to a
maximum of  8 inches, delivered  and loaded onto  rail cars by others.  The
costs for these operations are not included.

und°r the conditions that we have  outlined  for loadinp  and unloading.  Should
conditions at oririn and destination  conflict  with our  assumptions, chanres to
our operating nlan and projected rate would be in order.

      This has been a post interesting project and we have devoted considerable
effort to the development of the nlan.   Should you have nuestions concerning the
      , we would be pleased to discuss it with vou.

                      C&NW. 1C. EJ£E KAS7E DISPOSAL PROJECT
      Chicago £ North Western, Illinois Central, and Elgin, Joliet and Eastern
Railroads present the followinp rail handling plan and estimate of rail charges
for Black and Veatch's use in their larger project to provide preliminary estimates
of system requirements and costs for disposal of solid wastes from the built-up
area of Cook County, Illinois Central speaks for its subsidiary Chicago and Illinois
Western, who is also involved in the project.

GENERAL DESCRIPTION

      System design is based on projected 1985 quantities of solid wastes by major
category as follows:

                                               TONS PER YEAR

                       Residential refuse        2,500,000
                       Commercial refuse         1,300,000
                       Industrial refuse         2,500,000
                       Incinerator residue         450,000

      Twelve tentative locations for loading stations were suggested by Black -ind
Veatch to permit relativelv short haul distances for refuse collection vehicle.'; and
so that each stition could serve an area which wculd ^enerats about 2 GOQ tons ^er
day on a six day per week basis.  The map on the opposing page displavs: tentative
loading locations, the three rail carriers, and the disposal site in Northeastern
Grundy County referred to as Site No. 10.

      In connection with the refuse disposal, the creation of a 1,000 foot mountain
is being considered, using reck spoil from a deep tunnel project.  The mountain
would be designed for recreational use.  Possible rail transport of the rock spoil
is discussed in a separate report.

      The refuse would be compacted into containers measuring 9 ft. wide, 11-1/2 ft.
high, 20 ft. long, with a volumetric capacity of 60 yards.  This is a slight change
from the suggested 10 X 10-1/2 X 20 and was made to accommodate RR Plate B clearances
for 65-ft. flat cars - 9 ft. width with ordinary truck spacing.  A density of ?>50
pounds per cubic yard is anticipated, producing a 20 net ton load per container.
Three containers would be transported on one 65-ft. flat car.  Container tare would
be approximately four tons each.  Gross weight of three loaded containers and the
flat car would be approximately 100 net tons.

      Separate loading sites have been studied for incinerator residue, recognizing
these plants are already at established locations.  However, volumes, spread over
four incinerator stations, do not promote special handling bv rail.  Savings
associated with open-top conventional rail cars are dissipated by the slower turn-
around of conventional handling and the need for separate unloading facilities.
Therefore, we have considered the incinerator residue being handled in the same
manner as the much larger volume of refuse - through the refuse loadinp stations.
The container could carry at least 20 tons of incinerator residue.

      The carriers have made only one su.rfested  change  re^ardinp  loading site
locations.  The area sho-.m on Black and  Yeatch's nap south  of the Sanitary  Canal
near Brighton Park Yard (GM60) should be relocated on the C£IW tracks  near  Crawford.

      Refuse collection has been stated  at a daily average  rate based  on a  six day
pickup.  Proponed rail handlinr is on a  six day  per week basis with  one  day dead tire
at all loading sites and Site lio. 10.  This in itself can accommodate  the daily averare
volures.  Seasonality and peakinr can be expected, running  120 per cent  peaks  durinp
sunrrer months with 80 per cent lows durinp, winter.  By  operating  the seventh day, a
peak of 116 per cent could be accommodated, assuninf, storape  capacity  at orir.in
stations.  We have provided for 3 per cent equipment spares and by holdinr  the
maintenance outap.e to 4 rer cent durinp  surner months and opsratinp  seven days, the
peaks could be net.  Cur estimated price contemplates 337 days operation: 6 days per
week year round, plus 25 additional days.

      EJ£E would have to operate a  terminal  at  Site Mo.  10,  leaking locomotive and
caboose servicing available.  A switch  crew  would be necessary  around  the  clock  for
train breakup and makeup.

      EJ&E road crews would be called at Site No. 10 for turnaround service  to West
Chicago (interchange CfcNW-EJSE) and  "atteson (interchange  IC-EJ6E).      C6NW-EJ6E
would interchange once every twelve  hours -  say 0:00 and 12:00  -  and IC-EJ&E would
interchange once every twelve hours  - say 6:00  and 10:00 - to facilitate an  even
arrival of loads at Site No. 10.  Match at West Chicago  and  t'atteson,  with return
loads in the case of EJ&E, and return empties in the case  of CSNW and  1C,  has been
conterplated and is a critical part  of  the economics of  the  rail  schedules.   Irter-
change would amount to the enpine and train  crews trading  a  loaded train with
run-through power and caboose for an empty train with run-through power and  caboose.

      C61IW would run two collection  trains daily from Proviso:  one picking up at
(A) Clybourn, (B) Mayfair, and (C)  40th Street;  and the  other at  (D) t/ilmette,
(E) DCS Plaines, and (F) Proviso,,  Two read  trains would run daily from Proviso
to West Chicago interchange and return.  C6JIW would also run two  empty distribution
trains daily from Proviso setting out in the reverse order of pickup.

      Cf.IW RR would run a crew daily from Crawford Yard  to pick up at  (G)  XcCook,
and (H) Crvr.'ford, and interchange with  1C at Crawford.   1C would  run a yard  crew
from tlarkham to pick up these loads at  the C6IW  interchange  and fill out at
(I) Fordharn - the crev would tie up at  "arkhan  Yard.  A  road crew would take the
loads to interchange with EJ&E at i'atteson and  raturn to t'arkham.  Yard  with cnoties..
A yard crev: fron Karkha- would deliver these empties to  (I)  Fordham and interchange
with Cf.I'*' R^ at Crawfrrc.  A C6IW crev; would deliver empties to (H)  Crawford and
(G) McCook.  1C would also run a road crew from  Xarkham  Yard, picking  up at  (J)
Wildwcod and (K) Markhan, delivering to L'J£E at  !'atteson and returning'with  empties
for set-off at (K) J'arkr.am and (J) V.'ildwood  before tying up  at  "arkham Yard,  "'ha
EJ&E site (L) 1-90 would be serviced six days per week with  existing crews.

      Crev; schematics are shown as Exhibits A and 3.  Those schedules allow a minimum
of 7 - 8 hours to unload at Site No. 10 and  eight hours  at: each of the loading sites.
Car set schematics are shown as Exhibits C and  D.  The tines at the  loading  sites
vary substantially in terms of hour  of the day.  Loadinr would  have  to be  accomplished
within the time the empties were there regardless if it  were 3:00 a.m. to  11:00  a.m.
or some other unusual shift.  The loading tiire  is the same at each individual station
each day, within tne reliability of the schedule.

      Cars and Containers:

      Service to C6NW origins would require three car sets.   The  sane  is  true of

TRACKS AND PERMANENT FACILITIES

      Track construction at origins for railroad purposes could theoretically be
limited to a single track long enough to hold the dailv number of loads at that
station.  This is possible because one crew is picking up loads and another  crew,
later in the day, is delivering empties.  However, if empties were ordered in and
not loaded they would have to be pulled out empty and run to Site Ho. JO - the
next day's empty supply is already on its way and there would be no place to put it.
Breaking the trains at Proviso and Markham to add or delete cars is not desirable
nor provided for.  We therefore conclude that each origin would need track capacity
for two days loading.  This allows unused empties to be left behind and gives tire
to adjust empty orders so as to work off the overage.

      There will always be a minimum of two car sets physically on hand at one time
at Site 10, plus the UO spares and other excess empties during low periods (train
arrivals and departures every six hours versus unloading on a 7 - 8 hour cycle).
At a minimum, a five track yard is necessary (each track 6500 ft. in longth):
three tracks for cars on hand, one track tc use as a run-around, and one track to
protect possible arrival of a loaded train  before departure of an er.pty train.
These tracks are for arrival, departure, and train makeup purposes.  Tracks necessary
for unloading would be in addition.

      Diesel fu^linr and inspection facilities and c-iboose servicirtf tracks would
be necesr.rtrv.  Protective buildings dnd nanit-ary facilities for crew members, car
inspectors, and supervisors would bo required.

RAIL  RATES

      Our study indicates that rail rates of $1.20 net ton are feasible including:

      1. Crew expense;
      2. Locomotive repair and maintenance, exclusive of ownership costs and
           facilities at Site 10;
      3« Car repair and naintenance, exclusive of ownership costs;
      U. Track repair and maintenance, exclusive of ownership of origin and
           destination trackage;
      5. Upgrading of EJ&E's Illinois River Line;
      6. Contingencies, overhead and rail profit.

      The figure contemplates six day per week crew schedules as outlined, and 25
days  of seventh day operation.  The carriers would need a minimum charge oer day,
regardless of cars handled, to protect the schedule.  This is an overall averape
pricing approach for the entire job as defined to us.  The manner of collecting
these charges is not yet clear.  There could be separate charges from various
origin groups reflecting the particular cost characteristics of servicing that area.
This would protect against high volur.es developing at high cost origins and low
volumes at low cost areas to the detrirent of an overall average price.  It would
also  facilitate the rate treatment of new origin stations on a cost oriented basis.

     We have specificallv excluded certain ownership costs from the above fipure
for practical reasons.  The carriers cannot forecast their ability tc borrow
capital in the 1980's, nor interest rates and depreciation laws that would apply,,
All of these have a bearing on conversion of the capital costs to a cents per ton
figure.  It could well be that the apency would have rore advantageous circurstances
than  the carriers, which would mean that they should own the equipment.  If you
assume an 8 per cent cost of borrowing and a ten year amortization period, conversion
of the capital cost to $.44 net ton is possible as outlined on Exhibit F (Summary
of Capital Cost).

     This would bring the cost to a total of $1.64 net ton still exclusive of con-
tainer ownership ana repair and maintenance.  The methods chosen to compact the
refuse in the containers and to disgorge the contents will greatly influence their
original cost and the maintenance necessary.  At the present time the carriers do
not have insight into tr.ese loading and unloading matters and cannot make a reasonable
estimate of costs in this area.  As a point of design, however, we supgest a wedpe-
shaped bottom which would secure itself into a deep well in the floor of the car.
This would provide a simple method of holding the containers on the rail cars
without latching or locking devices which would require activation and maintenance.

     We are pleased to be able to work with you in the development of this project
and stand ready to furnish additional data and firm quotes as the development of
the project merits.

     These figures are at 1970 wage and price levels and would have to be reviewed
and uo-dated at the tine of decision to handle via rail.

         TRANSPORTATION OF WASTE ROCK FROM DKEP TUNNEL DRAIN'AGE SYSTEM

                           CHICAGO SANITARY DISTRICT
        During periods of high precipitation, storm water runoff infiltrates
Chicago's sanitary sewer collection system to such an extent that the combined
sewerage exceeds the capability of the treatment facility.  The Metropolitan
Sanitary District of Greater Chicago has propcsed to eliminate this condition
through creation of underground reservoirs to store the excess flows for sub-
sequent treatment during periods of low flow.  Creation of the "Deep Tunnel
Drainage System," as it is called, will require the removal of 200 million
tons of rock from three excavation sites in Chicago over a ten year construction
period.  The disposal of this amount of waste rock in or around Chicago presents
still another problem to the Sanitary District.  Cnc proposed solution is to utilize
the material to construct a ski-hill on a site about twelve miles southwest of
Joliet (called Disposal Site 10).

        Elgin, Joliet and Eastern Railway Company serves the proposed site for
construction of the ski-hill and also connects with all rail lines entering the
City of Chicago.  For these reasons it is in position to uursuo transportation
of this product via rail from the three prooosed excavation sites even thour.h
the precise location of these sites is not deter-.ined and the particular rail-
roads with whom EJfcE would be working are not known.

        Our studies have been based on the following annual figures for a ten year
period:
                                             Net Tons per
                        Excavation Site          Year	

                        Northside              4,000,000
                        Southwest             14,000,000

                                   TOTAL      20,000,000

        No information was available as to the mining techniques to be utilized
or the type and size consist of the material to be produced.  Our principal
concern here in developing a transportation system is the size of the product as
it might be tendered to the railroads and the methods that would be available to
load and unload such material.  EJ&E engaged a consulting engineering firm whose
principal activity involves large scale mining and transportation methods.  For
purposes of their feasibility study, it was assumed that the material excavated
would be run-of-mine dolomitic limestone, having a weight of approximately 10n Lbs.
per cubic foot upon delivery to the railroads.  To represent the worst possible
condition for the railroads, the studv was bused on the premise that the rock
would DO loaded after blasting by track Jess minim- t-jut risen t for haulare to a
shaft or skioway wher-j it would be hoisted to the ;urface and durned into a roc-.et
or bin in the head frame for subsequent aisoosal.  Considering retnoas avai-laois

 for  loading, unloading, and distribution on the mountain of an unsized material
 versus a sized material, our consulting engineer has recommended crushing at
 origin.

      A flow sheet showing the material preparation and loading scheme is
 shown on Exhibit I.  A general description of the material handling concept
 is carried on Exhibit II.

 CRUSHING AND RAIL LOADING COSTS

      Capital costs of the crushing plants at the three sites, including surge,
 stockpile, and reclaim facilities, loadout facilities including tracks and roacs,
 fencing, repair and maintenance facilities, etc., total $10,931,000, as detailed
 on Exhibit III.  Annual operating costs for crushing and loading operations have
 been estimated at $2,311,400 or approximately 12 cents a ton.  Details are shown
 on Exhibit IV.

 RAIL UNLOADING AND FINAL PLACEMENT COSTS
      Capital costs of unloading and placement facilities at Disposal Site 10,
including rotary dur.per, rail terminal and yards, overland conveyor, mobile
stacker and spreader equipment total $12,277,000, as detailed on Exhibit V.
Annual operating costs of unloading and placement operations are estimated at
$3,360,500 or approximately 17 cents per ton.  Details of these costs are shewn
on Exhibit VI.

RAIL HAUL COSTS
      Assuming a 360 day work year, but only 92.5 per cent operating time, the
following tonnages would be available on a daily basis:

             EXCAVATION SITE     TONS PER YEAR     TONS PER DAY
             Northside             4,000,000          12,000
             Southwest            14,000,000          42,000
             Calumet               2,000,000           6,000

                  Total           20^000,000          60,000

      Five 120 car trains will be required each day to transport the waste rock
in 100-ton cars to the disposal site.  The schedule would call for one train per
day from the Northside site, three and four trains per day from the Southwest site
on alternate days, and one from Calumet every other day.

      A 100-ton car with swivel couplings appears to be the most economical
type for this service - winning out over the side dumn (with or without air
cylinders for self-dumping) and the bottom dump because of overall impact on the
cost of rolling stock plus unloading facilities.  A car measuring about 32 ft. coupler
to coupler and having anproximate inside dimensions of 28' X 9-1/4' X 7' should weigh
about ?n tens for this service and could re^.cilv carry 100 tons of waste rock at
its assumed loose weiflit of 100 Ibs,  per cubic foot.

                                   -3-
      Assuming a 1 per cent ruling grade against the loads on any of the routes
chosen, four 2000 HP diesel electric locomotives would be required to handle each
of the 120 car trains.

      The loading sites are capable of UOOO tons per hour and the locomotives
would stay on the train during loading operations.  Considering a runaround for
the locomotive and caboose at origin, the work should be accomplished in approx-
imately four hours.  The longest distance from any of the loading sites to the
disposal sites is approximately seventy miles and five hours running time in
either direction would appear adequate.  At the disposal site switch crews would
feed 40 car cuts of loads to the Barney for positioning in the rotary dunper, which
has an operating rate of 4000 tons per hour and should handle a trainload in under
four hours.  Considering traffic delays and contingencies then, it is very
realistic to expect a 24 hour cycle for each train.  Therefore, five car sets
of 120 cars would be needed and allowing for 8 per cent outage, an investment
in 650 cars would be required.  Considering switching service at the disposal
site and maintenance outage, 26 locomotives would be required.  Five read cabooses
would also be needed.  Capital requirements for rail haul are summarized be lew:

            650 cars          @  $ 20,000 each  =  $13,000,000
            26 locomotives    @   307,000 each  =    7,982,000
            5 road cabooses   Q    35,000 each  =      175,000

                            Total                  $gJ_, 157, OOP

      We estimate that operating costs for the schedule outlined above, including
locomotive and car repair and maintenance, crews, agency, maintenance of roadway,
plus overhead, contingencies and rail profit, would make possible rail rates cf
approximately 63 cents net ton, exclusive of depreciation.

SUMMARY
Total capital requirements for the entire project, including  crushing, loading,
rail haul, unloading and placement, are recapped below:

      If this cost were spread out over the 200,000,000 tons indicated for
the project life, the grand total capital costs might be viewed in the area
of 33 cents net ton, depending on prevailing interest rates and the ability
of the borrower to secure the loan.

      Summarizing further then:

        Operating costs for crushing and loading    - $ .12 net ton
        Operating costs for rail haul               -   .63 net ton
        Operating costs for unloading and placement -   ,17 net ton
        Capital and interest                        -   ,33 net ton

                                  Grand Total       - $1.25 net ton

      We have not been able to project the detail with regards to the haulage
of waste rock that we were able to build into our proceeding study concerning
the haulage of refuse simply because the origin railroads are not clear at
this time.  We would point out that certain improvements necessary on the
EJ&C in order to accommodate the refuse movement are prerequisite to the move-
ment of waste rocK, and if for any reason the rock should be considered without
the refuse, the figures indicated in this report would have to be revised up-
ward by some small amount.  Also, our figures in this study do not recognize
the cost of land acquisition.

      All estimates are based on current wage and price levels and, of course,
these would have to be up-graded at the time the project was to take form.

             GENERAL DESCRIPTION OP MATERIAL HANDLIKG CONCEPT
      The rock would be loaded, after blasting, by trackless mining equip-
ment for haulage to a shaft or skipway where it would be hoisted to the
surface and dumped into a pocket or bin in the headframe for subsequent
disposal.

      In the design depicted by the schematic flowsheet, the run-of-mine
rock in the bin would be fed by a pan feeder to a vibrating grizzly where
the plus 8-inch material would be scalped off for primary crushing.  The
product from grizzly and crusher would then be pan-fed to a vibrating
screen from which the through product would drop to the out-haul belt and
the oversize discharged to the secondary crusher for a further reduction
in top-size before joining the by-passed material on the out-haul belt.

      The ninus 4-inch material, possibly with soire tramp oversize, would
then be conveyed to the surge pile for accumulation in live storage between
railcar loading, operations.  Withdrawal from stockpile would be by under-
ground draw points with pans feeding the out-haul belt to the 500 ton
pcckct at a rate comr.cnnurate with that required for the optimum car loading
schedule.

      Rail haul of the material to the disposal site would be in 100 ton
cars, equipped with swivel couplings for roll-over dumping, made up into
120 car trains powered by four 2000 HP diesel locomotives.

      At the disposal site, the train would be broken into forty car cuts
for feed to a rotary clunper equipped with a positioner, or "Barney," for
accurate spotting of the cars.  After the cars had been dumped into a bin,
the material would be pan-fed to an out-haul belt for transfer to the
"overland" conveyor which, in turn, would discharge onto the rail-mounted
trailing conveyor of the stacker.

      The rotating, luffing boom stacker, mounted on either rail trucks or
crawlers, would then either deposit the material in its final position or
would transfer it to rubber-mounted, high-speed scrapers for controlled
placement.   The scrapers could also be used for loading, hauling, placing
and compacting a suitable top dressing for the ski-hill from local borrow
pits.

        multiple-use facility.

-------
A  transfer point was located along the
river near the western boundary of the
site. This site  was selected  because of
its  potential   for  receiving  materials
from  three  modes of  transportation:
rail  movement,  road   vehicles   and
barge  transport  through   the  inland
waterway system, and  because of an
existing  70  foot bluff which visually
isolates the site  from  the surrounding
countryside.

-------
The  construction  techniques   to   be
used and the patterns of on-site move-
ment of the material were based on the
projected final  shape of the mountain
and its relationship to  the  overall  site
plan. In general, the mountain  is plan-
ned to be constructed  from the south
towards the  north  with an ultimate
projected  increase 6f  1000 feet  over
existing elevations.
Throughout  the  development  of  the
mountain  facility, portions  of the site
will be  made available  for  recreational
use.  The  areas  around the mountain,
between the edges of  the site and the
base of the mountain construction will
be made immediately available  for use
as a recreations!  facility.  These periph-
eral areas will  form visual  barriers  be-
tween  the on-site  work  and  the  sur-
rounding countryside.  As the construc-
tion of the mountain moves northward
and  upward,  portions  of  the  original
construction  areas  will  be  landscaped
and  utilized.  By the  time  the  final
 construction is completed at the north-
 ern boundary  of  the site,  major  por-
 tions  of the facility  will be in constant
 use.
                                                                                    i

-------
The development  of  a  1000 foot high mountain
that is  integrated  visually  into  the flat  Illinois
topography was the second  area of considera-
tion.  The  final design  shape of  the mountain
resulted from the synthesis  of anticipated recrea-
tional demands, construction techniques, drain-
age, landscape design, and topographic and visual
considerations. The mountain is designed to  be
an  extension  of the  existing  native landscaping,
ravines  and   gullies  along  the  waterway.  The
result is a  visually pleasing  mountain aestheti-
cally integrated into  the Illinois topography and
designed for  maximum  multiple use potential.

The development  of the Site Plan was divided
into three  main areas  of consideration:  recrea-
tion, conservation and natural science education.

The mountain was designed to provide a recrea-
tional facility which will afford people of all age
groups and interests an  opportunity  to  partici
pate  in  a  variety of  year round  recreational
activities  in   an  atmosphere  which  will insure
maximum enjoyment.

The Ski  Mountain Plan provides for  the  conser
vation of natural  resources and the development
of  new,  permanent open space areas.  The Moun-
tain will be landscaped to encourage the growth
of native grasses,  plants and trees, recreating the
indigenous  Illinois landscape  while providing a
natural  habitat for a wide range of animals  and
birds.  In addition, areas will be  designed to
provide natural habitats  for  selected species of
animals and birds which  are in danger of extinc-
tion. Specifically designated sites within densely
wooded areas will  become sanctuaries for  larger
animals such  as deer, fox, beaver  and  badgers.
The entire site will be designed to act as a living
museum of native plants  and wildlife.

The Ski  Mountain, with  its programs of conser-
vation,  reconstruction and  wildlife preservation,
will  provide an ideal setting for the construction
of  a natural  science  education   facility.  The
planting  of native plants and the  presence of
common  and  rare  species of  native wildlife  will
provide a  setting  for the  education of all  age
groups,  beginning  at  the grammar  school level
and  progressing through sophisticated  graduate
                                                     The site  was divided into three areas  for plan-
                                                     ning of  ultimate  use. Area No. 1 with its ideal
                                                     sun orientation, was designed as an active recrea-
                                                     tional  facility.  Area  No. 2 was designed as  a
                                                     conservation area and natural science education
                                                     facility,   and Area  No. 3  was  designed as  a
                                                     passive recreational facility. Due to its proximity
                                                     to the receiving and transfer  point, Area No. 3
                                                     would be the last area  developed for  ultimate
                                                     use. Although  activities  are  primarily  located
                                                     within the specific area designed for them, many
                                                     functions overlap creating a single, unified facility.

-------
Area  No. 1,  the year-round  active  recreational
area is  visually identifiable by  its  three bowl-
shaped areas, specifically formed and oriented to
capture and  retain the winter snows. The three
bowl-shaped  areas,  ranging  in  vertical  height
from  300  to  500 feet on  the south and up to
1000  feet on the  north,  provide skiing traits
with varying  degrees of difficulty.  In addition to
the skiing facility, which provides the site's most
dynamic recreational resource  the area  is plan
ned to contain numerous additional recreational
facilities.

The lakes, which provide  the  mnoff, silt, and
pollution control during the construction phases,
are to be utilized as  a  source of water  oriented
recreation  on  a  year-round  basis.  During  the
warm  weather, the  lakes  are  to  be used  for
swimming, fishing, boating and sailing.   Winter
activities  include  ice fishing, ice skating, speed
skating, ice hockey and ice boating. Pollution of
the lakes will  be  prevented by  constructing  the
mountain with essentially stable  material and by
collecting  water  which percolates  through  the
fill and  treating  it  to remove or  stabilize any
pollutants. In  addition, a complete interception
system would be  provided  for collecting surface
runoff before  it  enters the  lakes.  This  would
include surface ditching, subsurface piping, and
retention reservoirs.  The  interception and con-
trol  system  would  prevent surface water from
entering directly into the  lakes. Upon the  detec-
tion of a nutrient within  the  retention reservoir
the water  would  be recycled over cropland for
nutrient removal.  In addition to the interception
system, a 100-foot wide barrier surrounding the
lakes would  be developed, including very deep-
rooted  trees and shrubs — its  purpose being the
interception  by the  root system  of  any high-
nutrient subsurface water.

The  low hills surrounding  the lakes are designed
for use  in the winter time for  toboggan runs,
and the  most gently  sloping hills at the base of
the mountain become sledding runs.

A  complete   public  convenience   facility,  in-
cluding  specialty  shops,  restaurants and  lodge
facilities,  is  located  between  two  lakes  at  the
base of  the  center bowl.  This facility could be
expanded into a regionally oriented convention
and sports center  for family enjoyment within a
short distance  of the Chicago  metropolitan area.
Across the lake from  the  lodge and in the open
space at the  base  of the center bowl, a ski jump
facility  is planned to  attract  national and  inter-
national  ski jump events.
Park facilities along the existing inland waterway
system  will  be expanded to  include a marina,
and  fishing  and sightseeing charter boats. The
road adjacent to the waterway will be improved
lo  facilitate  pedestrian and   automobile  sight-
seeing.  The  Channahon  Lock  on  the  former
Illinois and Michigan  Canal will be maintained as
an historical  landmark.

The  open  fields and  meadows around the base
of the  completed  mountain  will be developed
into family recreation areas which will  include
picnic  facilities, fields for sports such as base-
ball, football,  and  soccer, and open spaces  for
model airplane flying.

-------
The northern part of the site, designated as Area
No. 2,  is  designed as  a  large  and  significant
conservation area and  natural science education
facility. Automobiles will be excluded from this
densely covered wilderness area.  The reservoirs
in this  area  will be developed  into  marshes and
sloughs for use as natural  habitats for a variety
of native animals.  They  also will  provide  places
for birds to  rest  and feed during  their  migra-
tions.
The sides of the mountain within this area will
be heavily landscaped with native plants, ranging
from prairie grasses at the bottom of the slopes
through  small  shrubs and  trees and  finally  into
native forests.  They  will be specifically designed
to provide  habitats  for small and large animals
and birds which are native  to this region.
A natural science education facility consisting of
a nature  center with museum space, classrooms
and  laboratory facilities will be constructed at
the base of the mountain.  It will be utilized for
orientation   lectures  and   research  conducted
within the area. It will also be the starting point
for a series of hiking trails leading through and
around specific areas within the site to amplify
the educational programs.

-------
The area on the southwest portion of the moun-
tain site,  designated  as  Area  No. 3,  will  be
developed into a passive recreational facility.

This site  will  provide for family  camping,  in-
cluding facilities for  camping trailers, cabins and
tents.  These facilities  will be  provided  in and
around the  lakes  and  up  on  the  mountain
slopes.  All locations wil!  include necessary san-
itary facilities.  Specific areas will be set aside for
institutional use such as Thp Boy Scout Program.
The site will  be honeycombed with  equestrian,
bicycle and snowmobile trails for family use and
enjoyment.  Trails from these camping facilities,
as  well as from  other points,  will  lead to  an
observation point and  restaurant complex at the
highest point on the  mountain.

-------
The result of the three phase design approach  is
a mountain that visually  blends into  the Illinois
topography and  provides  a multiple  use recrea-
tional   and  educational   facility  for   all  the
residents of the Chicago metropolitan area.
