FOREWORD
The following pages of this Manual contain the design standards and the
administrative requirements for the issuance of sewer permits and outline
the procedures for permit application. The contents of this Manual have
been formulated with the courteous assistance of a Blue Ribbon Committee
representing a cross-section of concerned citizens, local governments,
builders, contractors and consulting engineers, with a view towards facili-
tating the issuance of permits. It is hoped that this Manual will reach, and
be used by, as many hands as may be potentially involved in the preparation
of the permit application and the other plans and documents related thereto.
For if it does, it is our hope that it will properly serve the purposes it is
intended for.
Let me assure you in this connection that the permit and all the entries
therein, together with the other information and documents related thereto,
are individually designed to serve specific and related purposes in our over-
all responsibility for the protection of the health and welfare of the public.
To be specific, the purposes served include: compliance of the project with
the minimum design standards; prevention of pollution by controlling flows
into the District systems, including flows into waters within the District;
prevention of overloading of the District interceptors and treatment plants;
and, equally important, the assistance to the District in planning for the
future to provide for flood control and to meet demands of population growth
as reflected by new construction projects.
It is our sincere hope that this Manual will prove beneficial to you and that
you will be generous in extending your cooperation and assistance so that,
in turn, we will be able better to serve you and serve and protect the public.

MANUAL OF PROCEDURES
FOR THE ADMINISTRATION OF
THE SEWER PERMIT ORDINANCE
SECTION I - APPLICABLE RULES AND REGULATIONS
Article 1. PERMIT REQUIREMENT
1-1. Purpose. The "Manual of Procedures for the Administration of the Sewer
Permit Ordinance", contained herein, is issued for the implementation, admini-
stration and enforcement of the provisions of The Sewer Permit Ordinance.
The Engineer of Local Sewers is designated as the authorized representative of
the General Superintendent to receive and review permit applications, to inspect
and approve construction under the permit, and to investigate violations of the
Ordinance.
1-2. Permit Requirement. Except as provided in Article 1-3, Exemptions, and
Article 1-4, Waivers, permit is required for all construction of sewers and
sewer facilities within the territorial boundaries of the Metropolitan Sanitary
District, whether such construction is on private or public property. Permit is
also required for existing buildings when the use of the building changes to a use
for which a permit is required. Unless the Ordinance contains clear language
granting a specific exemption as indicated herein, the intent is that no exemption
is granted. It is the responsibility of the General Superintendent to interpret,
administer and enforce the Ordinance within the authority granted to him by the
Board of Trustees.
1-3. Exemptions. A building service sewer (See Article 4-4) constructed to
serve a single building devoted solely for residential purposes and containing
less than twenty-five (25) dwelling units is exempt from the sewer permit require-
ment. Any extention of said service sewer is a violation of the Ordinance.
Any sewer constructed in the public right-of-way or easement, except for crossing,
is considered a lateral and is not exempt from the permit requirement, even
though it may serve a single building containing less than twenty-five (25) dwelling
units. Except as herein provided, all other construction requires a permit.
1-4. Administrative Waivers. The administrative waiver is a procedural
exemption under the Ordinance. Subject to certain requirements, administrative
waivers may be granted by the District to the Permittees for specific types of
non-residential buildings only if those Permittees have complied with the re-
quirements for administrative waivers. Requirements and procedures for ad-
ministrative waivers will be furnished by the District upon request.
1-5. Permittees. The District recognizes as Permittees the parties listed below
as provided in Section 2(h) of the Ordinance. The Permittee' is held responsible for
compliance with the conditions of the permit.
a. Any municipality, municipal corporation, sanitary district, utility company,
township government or any other governmental body.
b. Any municipality, municipal corporation, sanitary district, utility company,
township government or any other governmental body jointly with any individual,
individuals or corporation where application is made for installations on private
property.
C. Any individual, individuals, or corporation who owns property directly
adjacent to an interceptor sewer of The Metropolitan Sanitary District of Greater
Chicago, where direct connection to said interceptor is made or is contemplated
by the owner of said property for the sole, exclusive and perpetual use of the owner
of said property (and where the direct connection serves only that property immedi-
ately adjacent to said interceptor), who seeks permission to discharge sewage,
industrial waste or other waste into facilities of The Metropolitan Sanitary District
of Greater Chicago.
d. Any individual, individuals or corporation who provides an acceptable
sewage treatment plant for the sole, exclusive and perpetual use of the owner of
the property being served thereby, which discharges into any waters or intercep-
tor sewer of The Metropolitan Sanitary District of Greater Chicago in conformity
with the Ordinances of The Metropolitan Sanitary District of Greater Chicago, the
Rules and Regulations of the Illinois Sanitary Water Board and the Statutes of the
State of Illinois.
e. Any responsible individual, individuals, or corporation, (not otherwise
qualified as permittee under the provisions of Section 2(H)2, 3 or 4 of the Sewer
Permit Ordinance), upon presentation of satisfactory evidence of responsibility
as determined by the Board of Trustees, where construction of sewers or
sewerage systems is contemplated to serve property owned by said individual,,.
individuals, or corporation, in an unincorporated area, and the contemplated
construction is intended for the sole, exclusive and perpetual use of the owner;
provided that said unincorporated area is outside the jurisdiction of a local
sanitary district and outside the area of a public utility company certificated for
such service, and the township government declines to execute the permit
application and to assume the obligations of a joint permittee, as provided in
Section 2(H)Z of the Sewer Permit Ordinance.
1-6. Joint Permittees. In addition to those cases where the requirement for joint
permittee is mandatory under the Ordinance, permits may be issued to joint permit-
tees if so requested by the local governmental body having jurisdiction.
Article 1-5e amended October 26, 1972

1-7. Permittees Under Previous Ordinance. Nothing contained in Article 1-5 shall
operate to annul permits previously issued for the construction of sewers under the
Ordinance then in bffect, except that in unincorporated areas where a permit had
been issued to an individual owner as Permittee, if said owner -Permittee shall
abandon, or transfer the ownership of, the sewer system constructed under a per-
mit and the area served becomes subsequently incorporated or is annexed to a duly
constituted local government, sanitary district or utility company, the local authority
assuming jurisdiction over the area shall thereby become the Permittee for said sys-
tem and shall thereafter be responsible for the proper maintenance and operation of
the system.
1-8. Definitions. For the purposes of the Metropolitan Sanitary District, the fol-
lowing definitions shall apply:
a. "Sewage" means water -carried human wastes or a combination of water -
carried wastes from residences, business buildings, institutions and industrial
establishment, together with such ground, surface, storm or other wastes as may
be present.
b. "Industrial Waste'f means the solids, liquids or gaseous waste resulting
from any industrial, manufacturing, trade or business process or from the develop-
ment, recovery or processing of natural resources.
C. "Other Wastes" means all decayed wood, sawdust, shavings, bark, lime,
refuse, ashes, garbage, offal, tar, chemicals and other substances except sewage
and industrial wastes -
d. "Maintenance" means keeping the sewer lines, sewer systems, sewer
facilities or sewage works and structures in satisfactory working condition and
good state of repair, (including but not limited to preventing any obstructions or
extraneous materials or flows from entering said facilities, protecting said facili-
ties from any damage, and keeping same free from defects or malfunctions), and
making necessary provisions and taking necessary precautions to assure that said
sewer facilities are at all times capable of satisfactorily performing the services,
and adequately discharging the functions and producing the final results and purposes
said facilities are intended to perform,discharge or produce.

nor an opinion by the District regarding the equality or superiority of the
performance qualities of any of the materials.
3-6. Workmanship. As a minimum requirement all sewer pipes shall be laid in
accordance with the applicable ASTM specification. The specifications for the
construction of any sewers within the District shall not be less stringent than
the "Standard Specifications for Water and Sewer Main Construction in Illinois"
(The Red Book), adopted by a joint committee of the Illinois Society of Pro-
fessional Engineers Consulting Engineers Council of Illinois, Illinois Chapter

3-8. Curvilinear Sewer. Available information based on field data falls short
of providing conclusive evidence in support of the practice of curvilinear align-
ment for sewers 24" or less in diameter. Where local governments elect to permit
the construction of curvilinear sewer, it is mandatory that available maintenance
equipment be evaluated and proper equipment acquired.
When permitted by the local government, construction of sewers 24" or less in
diameter on curvilinear alignment shall be subject to the following criteria.
a. Alignment: Alignment shall follow the general alignment of the street.
Curvilinear sewer alignment shall be limited to curved street areas.
b. Curvature: Only simple curves may be used.
C. Radius: Minimum radius shall be no less than 200 feet.
d. Minimum Slope: The minimum slope shall be that which produces
a minimum velocity of 2.0 fps (Hydraulics of curvilinear alignment to be taken
into account.)
e. Manhole Location: Manholes are required at the point of beginning and
at the end of the curve and at the point of inflection. (PC, PT and PRC).
f. Deflection: Deflection of pipe shall not exceed the maximum deflection
recommended by the joint manufacturer. The deflections shall be uniform and the
finished installation shall follow a smooth curve.

ments, floors, rooms or occupancy areas below ground level at the building site
and served by a public or private sewer system, shall have overhead plumbing. No
permit application will be accepted, nor any permits issued after December 31,
1970, to any municipality or local government unless said municipality or local
government shall have adopted an ordinance requiring overhead plumbing, and a
copy of said ordinance shall have been filed with the Metropolitan Sanitary District,
or that the permittee and/or co -permittee shall agree to comply with the require-
ments of this Article.
4-2. Datum. The datum shall be indicated on the plans submitted. All plans shall
preferably be based on the Chicago City Datum which is established as:O.000.C.D.=
579.48 ft. above Mean Sea Level (1929 Adjustment) or 579.88 ft. above Mean Tide
New York. If any other datum is used, a conversion equation shall be shown on the
plans to relate the datum used to the Chicago City Datum.
4-3. Pipe Bedding. Bedding, other than concrete embedment, shall consist of
gravel, crushed gravel, crushed stone or crushed slag, 14" to 1" in size. As a
minimum, the material shall conform to the requirements of Article 704.01 of the
"Standard Specifications for Road and Bridge Construction", of the State of Illinois
or ASTM C-33. The gradation shall conform to gradation CA 11 or CA 13 of the
Illinois Standard Specifications or to ASTM Gradation No. 67. The pipe shall be
laid so that it will be uniformly supported and the entire length of the pipe barrel
will have full bearing. No blocking of any kind shall be used to adjust the pipe
to grade except when used with embedment concrete. Bedding shall be required for
all sewer construction, except ductile iron pipe, and shall be of a thickness equal
to ';th of the outside diameter of the sewer pipe with a maximum thickness of eight
inches (8") but shall not be less than four inches (4"). Where polyvinyl chloride
(PVC) pipe is specified, the backfill material to a level two inches (2") over the
top of the pipe shall be of the same material as the bedding material specified
above and shall be carefully placed so as to completely fill the space under and
around the pipe, in eight inch layers, loose measurement, and compacted to the
satisfaction of the Inspection Engineer named in the Permit.
Where unsuitable material is encountered at the grade established, all such unsuitable
soil shall be removed under the pipe and for the width of the trench, and shall be
replaced with well compacted bedding material, to the satisfaction of the Inspection
Engineer named in the Permit.
Where rock is encountered, it shall be removed below grade and replaced with a
cushion of well compacted bedding material having a thickness under the pipe of not
less than eight inches (8").
4-4. Building Service Sewer. Building service sewer is defined as a sewer pipe re-
ceiving flow from a single building and connecting to a sewer main or lateral, and
constructed on private property, except for street crossing. The maximum length of
a building service sewer shall preferably be 120 ft. and shall not exceed 150 ft.
If the length is exceeded an intermediate manhole shall be built. A manhole or
clean-out shall also be installed every 150 ft. When the building service sewer
connects to a sewer lateral of a size not larger than the size of the service sewer,
a manhole shall be built at the point of connection.
Article 4-1 amended March 25, 1971.
Article 4-3 amended February 7, 1985.
F:3
Minimum d,:sign standards, and other requirerrants hereof, governing materials,
joints, infiltration, workmanship and maintenance for sewer mains and laterals
shall also apply to building service sewers. Horizontal and vertical alignment of
the service sewer shall be uniform and shall follow a straight line alignment. There
shall be no dips in the grade or fall in the line. Turns or bends kagz fired for the
riser, if any, or necessary to connect to the sewer Wye or tee, shall be made with
standard bends.
In those instances where the building service sewer is partially constructed from
the sewer lateral or main to a point other than the building to be served, the pipe
shall be tightly plugged using a manufactured plug. The plug shall be pre -wired
by the manufacturer so that it can be firmly secured in place.
4-5. Connection of Building Service Sewers to Sewer Mains. Building service
sewer shall generally enter the sewer main or lateral by way of an existing Wye
or tee. In the event of absence of the Wye or tee, the connection to the sewer main
or lateral shall be made by one of the methods indicated below. If another method
is desired, a detail shall be submitted for review and approval by the District be-
fore the connection is made. Indiscriminate breaking of the sewer main pipe is
not allowed.
a. Installation of a manhole.
b. Circular saw -cut of sewer main by proper tools ("Shewer-Tap" machine
or similar), and proper installation of hub Wye saddle or hub tee saddle, in accor-
dance with manufacturer's recommendations.
c. Remove an entire section of pipe and replace with a Wye or tee branch
section. Pipe section shall be removed by breaking only the top of one bell. After
the wye or tee branch is inserted, concrete shall be placed over the broken area
to a minimum thickness of 4" and to a dimension of 8" in all directions.
d. Using pipe cutter, neatly and accurately cut out desired length of pipe
for insertion of proper fitting. Use "Band -Seal" couplings, or similar couplings,
and shear rings and clamps to fasten the inserted fitting and hold it firmly in
place. Follow manufacturer's recommendations for the installation.
4-6. Inspection Manholes. An inspection manhole having a minimum diameter
of 48" is required for all commercial and industrial buildings. The manhole shall
be constructed on the building service sewer before it connects to the sewer main,
and preferably shall not be closer than five (5) ft. to the building. There shall be
no flow into the inspection manhole except flow from the building or buildings
for which the inspection manhole is intended. Manholes constructed on public
sewer, or on sewers receiving other :_ :. are not considered inspection man-
holes.
4-7. Sound Engineering Practice. The design and Supplementary design require-
ments contained herein do not replace and are not a substitute for sound engineer-
ing practice nor the professional ability and judgement of the design engineer.

Article 5. CONSTRUCTION WITHIN THE FLOODPLAIN
5-1. Issuance of Permit. No permit will be issued for sewer construction
within any municipality lying totally or partially within a floodplain, unless
the municipality shall have adopted a Floodplain Ordinance which has been
filed with and approved by the District as to minimum requirements for the
protection of the health and welfare of the public.
5-2. Minimum Requirements, Floodplain Ordinances adopted by the
municipality shall include the following minimum requirements,
a. Elevations and Limits. Highwater elevations and limits of
floodplain shall be established by the Ordinance based on the 100 -year flood,
as determined by the most recent and best available data listed in Article
5-4 below. If the 100 -year flood information is not available, the regulatory
base flood shall be the flood of record. When data of higher order becomes
available, data of lower order shall not be used for regulatory purposes.
b. Building Openings. A door sill, window sill, top of foundation,
or the bottom of any other opening in the outer walls of a building or
structure shall be constructed at an elevation not lower than 12" above the
established highwater elevation of the 100 -year flood and not lower than 12"
above the highwater elevation of the flood of record, if the 100 -year flood
information is not available.
c. Overhead Sewers. When the building wall encloses open space that
is below the base flood elevation, gravity storm and sanitary sewer connections
are specifically prohibited and overhead sewers are required for the sanitary
connections and sumps for the storm sewer connections.
d. Existing Buildings. Existing buildings to be connected into a
proposed sewer system within a floodplain must have sanitary connections
designed to protect the sewer system from flooding.
e. Floodways. Adequate flood channel provisions should be provided.
The width of the floodway should be determined in the field and should be
protected from encroachment by the zoning ordinance and by the use of
building setbacks. Floodway easements should be provided which permit
necessary public channel maintenance and improvement work.
f. Floodproofing. That part of the structure constructed within floodplain
areas below the highwater elevation must be floodproofed. The design must
include measure to cope with sewer backup, groundwater seepage, and
hydrostatic pressure.
10
g. Sanitary Manholes. All sanitary sewer manholes constructed
in the floodplain must be provided with watertight, lock -type covers, or the
rims must be raised to an elevation not lower than 12" above the highwater
elevation.
5-3. Conformance with Floodplain Ordinance. All projects constructed
within a floodplain area shall conform to the requirements of the floodplain
ordinance adopted by the local government having jurisdiction over the area
in which the project is located. The portion of the project lying within the
floodplain shall be delineated and the limits of the floodplain shall be clearly
indicated on the overall plans submitted to the District as part of the permit
application.
5-4. Floodplain Highwater Elevation and Limits. In reviewing submittals
for sewer permits, the District will base its review on the highwater
elevations and limits of the 100 -year flood as established by the most recent
and best available data. If the 100 -year flood information is not available, the
review will be based on the flood of record data. The data which will be used
by the District is listed below in descending order of overall accuracy,
completeness, and currentness. When data of higher order becomes available,
data of lower order will not be used.
(1) HUD Flood Insurance Studies (FIS), if certified by
Illinois Department of Transportation, Division of
Water Resources (IDOT-DWR).
(2) IDOT-DWR Regulatory Floodplain Maps and Profiles.
(3) Soil Conservation Service -Metropolitan Sanitary District
of Greater Chicago (SCS-MSDGC) Floodwater Management
Plans, using the "without project" data shown therein.
(4) Other detailed 100 -year flood studies, if certified by
IDOT-DWR.
(5) HUD Flood Hazard Boundary Maps (FHBM) and Approximate
FIS Data.
(6) USGS Maps of Flood -prone Areas.
(7) USGS-NIPC Hydrologic Investigation Atlases (Floods of
Record).
When either the HUD Flood Hazard Boundary Maps or the USGS Maps of Flood -
prone Areas are used to determine the limits of the floodplain, then regulatory
highwater elevations shall be those of the flood of record.
5-5. Statutory Floodplain Requirements. All construction in the floodplain
must meet the requirements of the Rules and Regulations issued by the Illinois
Department of Transportation, Division of Water Resources, pursuant to "An
Act in Relation to the Regulation of the Rivers, Lakes, and Streams of
Illinois" as amended (Illinois Revised Statutes, Chapter 19, Section 52-78;
specifically Section 65f) and a permit from said Department must be obtained
for such construction.
Article 5 amended February 9, 1978, effective October 1, 1979.
Article 6. STORM WATERS.
6-1. Separation of Storm Waters and Sanitary Sewage. Except as provided in
Article 6-2 below, all new sewer construction shall provide two separate and dis-
tinct sewer systems as follows:
a. Storm Sewer Systems. The system shall be for the collection and con-
veyance of surface run-off and other storm waters. All storm waters shall be
collected and conveyed in a pipe or ditch system to the point of discharge in the
receiving natural or man-made stream or drainage ditch. No storm waters shall
be allowed to enter the sanitary sewer systems except that in "Combined Sewer
Areas" only, the storm waters are allowed to be discharged into the MSD inter-
ceptors.
b. Sanitary Sewer Systems. The system shall be for the collection and
conveyance of sanitary sewage consisting of domestic and other water -borne wastes.
All sanitary sewage shall be collected and conveyed in a pipe system to the point of
discharge into an existing sanitary sewage system, MSD interceptor or treatment
plant. No sanitary sewage shall be allowed to enter any storm sewer system or
discharge onto the ground or into receiving streams, without first having been
treated.
6-2 Combined Sewer Areas. In areas designated as "Combined Sewer Areas" on
the Metropolitan Sanitary District maps, the following requirements shall apply:
a. Separation. Complete separation of sewers shall be provided within
the property lines.
b. Detention. Detention shall be provided and/or permanent constrictions
shall be built on the storm sewer system to control the flow into the existing com-
bined system in accordance with the requirements of the local government.
C. Down-Spouts.All down -spouts or roof drains shall discharge onto the
ground or be connected to storm or combined sewer. No down -spouts or roof
drains shall be connected to the sanitary sewers.
d. Footing Drains. Footing drains shall be connected to sump pumps, and
discharge shall be made into storm sewers, combined sewers or drainage ditches.
No footing drains or drainage tile shall be connected to the sanitary sewer. After
December 31, 1970 all new construction shall conform to the requirements of this
paragraph. No permit application will be accepted, nor any permits issued after
December 31, 1970 to any municipality or local government unless said municipality
or local government shall have adopted an ordinance reflecting the requirements of
this paragraph and a copy of said ordinance shall have been filed with the Metropo-
litan Sanitary District, or that the permittee and/or co -permittee shall agree to
comply with the requirements of this Article.
Article 6-2d amended March 25, 1971.
12.
e. Floor Dr Floor drains in basements b..,.-. be connected to sump
pumps and discharged to the sanitary or combined sewers.
f. Sump Pumps. Sump pumps installed to receive and discharge ground
waters or other storm waters shall be connected to the storm or combined sewers
or discharge into a drainage ditch. Sump pumps installed to receive and discharge
floor drain flow or other sanitary sewage shall be connected to the sanitary or
combined sewers. A sump pump shall be used for one function only, either the
discharge of storm waters or the discharge of sanitary sewage.
6-3. Separate Sewer Areas. In areas served by separate sewer systems, the
following requirements shall apply:
a. Down Spouts. All down -spouts or roof drains shall discharge onto the
ground or be connected to storm sewer. No down -spouts or roof drains shall be
connected to the sanitary sewers.
b. Footing Drains. Footing drains shall be connected to sump pumps, and
discharge shall be made into storm sewers or drainage ditches. No footing drains
or drainage tile shall be connected to the sanitary sewer. After December 31, 1970,
all new construction shall conform to the requirements of this paragraph. No per-
mit application will be accepted, nor any permits issued after December 31, 1970, to
any municipality or local government unless said municipality or local government
shall have adopted an ordinance reflecting the requirements of this paragraph and a
copy of said ordinance shall have been filed with the Metropolitan Sanitary District,
or that the permittee and/or co -permittee shall agree to comply with the require-
ments of this Article.
C. Floor Drains. Floor drains in basements shall be connected to sump
pumps and discharged to the sanitary sewers.
d. Sump pumps. Sump pumps installed to receive and discharge ground
waters or other storm waters shall be connected to the storm sewer or discharge
into a drainage ditch. Sump pumps installed to receive and discharge floor drain
flow or other sanitary sewage shall be connected to the sanitary sewers. A sump
pump shall be used for one function only, either the discharge of storm waters or
the discharge of sanitary sewage.
e. Completion of Storm Sewer System. The construction of the proposed
storm sewer system shall be completed before the sanitary sewer system is put
in service. When compliance with this requirement may cause an undue hardship
to the Permittee, the Permittee shall so notify the District and the District may
waive this requirement if the conditions so warrant.
f. Window Well and Area -Way Drains
shall be connected to the sanitary sewer.
Article 6-3b amended March 25, 1971

6-4. Storm Water Detention in Unsewered and Separate Sewered Areas
a. General. It is recognized that the receiving streams within the District
do not have the capacity to receive and convey the increased storm water runoff
resulting from rapid urbanization occurring in many areas. These receiving streams
are subject to frequent flooding which results in a growing rate of property damage.
It is the intent of Section 3(B) of the Sewer Permit Ordinance to encourage local
governments and developers to jointly participate in providing detention storage
to eliminate the excessive runoff during heavy storm periods. Where impervious
areas are planned or contemplated, it is the intent that detention be provided as
required by the provisions hereinafter set forth. It is proposed that well maintained
landscaped areas would be provided to act jointly as detention reservoirs and
recreation facilities or aesthetic focal points in new village parks, either in
incorporated or unincorporated areas, forest preserve areas, county parks, housing
developments, shopping centers, industrial parks, etc. Other control methods to
regulate the rate of storm water discharge which would be acceptable include detention
on flat roofs, parking lots, streets, lawns, underground storage, oversized storm
sewers with restricted outlets, etc.
It is recognized that in order to better serve the long-range interests of the local
communities and the Metropolitan area, comprehensive basin -wide planning for
flood control should be formulated, adopted and implemented. Comprehensive
planning is far more beneficial than the proliferation of small, on-site detention
areas, although on-site detention does provide protection and is acceptable for
compliance with this Ordinance. The District may be called upon by the local
governments to render advisory, technical and other assistance for the formulation
ind implementation of a drainage plan.
b. Requirements. Pursuant to the provisions of Section 3(B) of the Sewer
Permit Ordinance, a sewer permit will not be issued after January 1, 1972, unless
1) The permittee (governmental body) has adopted a Storm Water Detention or Flood
7ontrol Ordinance acceptable to the District, and has on file with the District, an
pproved drainage plan and schedule for its implementation, or (2) The permittee
)r co -permittee provide detention of storm water runoff as set forth in the following
rite ria.
(1) Allowable Release Rate. The release rate of storm water from all
evelopments requiring detention shall not exceed the storm water runoff from the
rea in its natural undeveloped state.
ecause of the flat conditions of the land in this area, channel configurations cut
y nature are generally unable to handle the runoff from high intensity rainfalls
id results in flood plain storage or spreading of runoff over the land areas during
e larger storm periods. In order not to increase the runoff from such areas after
ticle 6-4 amended May 27, 1971.
14.
development, the release rate must be limited to the carrying capacity of these
natural channels.
The District will accept the release rate of not greater than that calculated from
a storm of three (3) year frequency with a runoff rate coefficient of 0. 15, unless
the applicant can show by his detail calculations, which are acceptable to the
District, that the discharge rate of the natural outlet channel serving the area is
greater.
(2) Bypass. Drainage systems shall have adequate capacity to bypass
through the development the flow from all upstream areas for a storm of design
frequency assuming that the land is in a fully developed state under present zoning
or zoning proposed under a Comprehensive Plan. The bypass flow rate shall be
computed utilizing a runoff coefficient of not less than 0. 35. An allowance will be
made for upstream detention when such upstream detention and release rate has
previously been approved by the District and that evidence of its construction can
be shown.
(3) Design Storm. The live detention storage to be provided will be cal-
culated on the basis of the 100 -year frequency rainfall as published by the U. S.
Weather Bureau for this area. The detention volume required will be that necessary
to handle the runoff of a 100 -year rainfall, for any and all durations, from the fully
developed drainage area tributary to the reservoir, less that volume discharged
during the same duration at the approved release rate.
c. Exemptions. Under the provisions of this article, storm water detention
facilities meeting the criteria and requirements established herein are not required
by the District for the following projects, provided that the available outlet capacity
is adequate as determined by the Municipal Engineer. If the outlet capacity is not
adequate, then detention as determined by the Municipal Engineer will be required
to store that portion of the runoff exceeding the outlet capacity.
(1) Residential subdivisions, the plats for which were recorded prior to
January 1, 1972. If the subdivision or any part thereof is resubdivided, this
exemption shall cease. When a permit application is made to the District pursuant
to this exemption, the submittal must include a copy of the land plan and the plat of
subdivision or resubdivision, as approved by the municipality. The land plan must
show all the proposed layout and the intended use of the entire area involved.
(2) Non-residential projects having a total area of less than five acres.
(3) Residential non -single family projects having a total area of less than
five acres.
acres.
(4) Residential single-family projects having a total area of less than ten
15.
*d. Special Provisions:
(1) Multiple Outlets. In order to eliminate small multiple outlets,
generally designs requiring a release pipe of less than four (4) inches in diameter
are not acceptable.
,(2) Affidavit of Disclosure of Property Interest.
(a) As part of the submittal documents, for projects in the separate
sewered areas, the owner of the property upon which the project (for which the
permit application is made) is located, shall furnish in all instances an Affidavit of
Disclosure of Property Interest stating the aggregate total area of said property
and all other lands contiguous to said property in which the owner holds an interest.
The applicability of the detention requirements will be based on the total contiguous
area in which an interest is held by the owner.
(b) Where a permit application is made for sanitary sewer and the
area serviceable by the sewer is under the control of an individual or a legal entity
(directly or indirectly, in part or in full), the area of the project (for the purpose
of determining the applicability of the detention requirements) shall be considered to
be the total area owned or controlled by the applicant, and detention facilities or
provisions shall be made as part of the permit for the total area.
If the area serviceable by the sewer is not in its entirety under the control of the
applicant, the applicant shall be responsible to provide detention facilities only
for that part of the area which is under his control.
(c) In all instances where the property which is the subject of a permit
is less than five (5) acres (or less than ten acres for residential single family
projects) and detention is not provided as part of the permit, the applicant shall
furnish to the District, as part of the submittal, an Affidavit of Disclosure of
Property Interest with respect to the property, which is the subject of the permit
stating that:
(i) The owner of the property has no interest, nor did he have any
interest at any time during the previous two years in any land contiguous to said
property, such that the aggregate total area of the property and the contiguous lands
exceeds five (5) acres,
(ii) The owner covenants and agrees that if within two years
after the issuance of the permit he acquires any interest in lands contiguous to
the property such that the aggregate area of the property and the contiguous lands
exceeds five (5) acres, the owner shall provide for storm water detention for the
entire aggregate area.
Article 6-4d amended April 17, 1975; effective July 1, 1975.
16.
(iii) No owner of any lands contiguous to the property has any
interest in the property such that the aggregate total area of the property and the
contiguous lands exceeds five (5) acres.
For the purpose of this article, the following definitions shall apply:
Owner: means record title holder or a beneficiary of a land trust which
is the record title holder, and includes singular and plural; if the owner is other
than an individual, the term includes beneficiaries, agents, shareholders, officers
and directors.
Ownership: means holding of record title or any beneficial interest.
Interest: means property interest or contractual interest, legal or
equitable, directly or indirectly, in part or in full, and includes option to buy.
In the case of a shareholder interest, the shareholder shall be deemed to have an
interest if he owns or controls 57u or more of the shares.
Contiguous: means adjacent to and touching at one point or more; if the
lands are separated by an easement or a dedicated right-of-way, it shall be
considered contiguous.
(3) Recording: Under special and unusual circumstances, where conditions
so warrant as solely determined by the District (generally where sewer connections
are not proposed), the District may issue the sewer permit without detention being
provided for the entire area as part of the submittal and place a special condition
on the permit that on-site detention will be provided for each future project within
the area regardless of the area of the individual future project, provided that a
Notice of Requirements for Storm Water Detention in connection with the permit
issued by the District shall be recorded with the Cook County Registrar of Torrens
Titles or the Recorder of Deeds of Cook County, as an encumbrance against the
entire area.
Before such permit is issued by the District, the applicants shall furnish as part
of the submittal, preliminary plans and design showing in adequate detail the
manner in which the detention requirements will be satisfied by future projects
within the area which is the subject of the permit. If, as part of the preliminary
plans and design, it is proposed that the detention requirements will be satisfied by
providing on-site detention facilities for individual future projects, the facilities
shall be designed such that the minimum size of the area served by such facilities
shall not be less than three (3) acres. The areas for which the detention facilities
are designed shall be delineated on the preliminary plans. If individual lots having
an area of less than three (3) acres each are proposed for development in the future,
such lots shall be jointly developed so that the minimum area for which detention
17.
facilities are designed and provided shall not be less than three (3) acres.
Individual projects developed within the area which is the subject of the
permit shall conform to the preliminary plans made a part of the permit with
respect to providing detention facilities to satisfy the detention require-
ments or provide alternate design meeting the intent of the preliminary plans
and of the detention requirements as outlined herein.
Where only the name of the permittee appears on the permit application, the
permittee shall furnish to the District as part of the submittal an affidavit
that the permittee is aware of the above requirements and will require any
person connecting to the sewer which is the subject of the permit to comply with
these requirements. Permits issued under the provisions of this article will
contain a condition to the effect that the permittee will require any person
connecting to the sewer to comply with the requirements contained herein.
6-5. Correction of Existing Deficiencies in Separate Sewered Areas.
It is recognized that the existing separate sanitary sewers within the MSDGC
service area were designed and intended to receive and convey only domestic and
industrial wastewaters together with a limited amount of groundwater infiltration.
Stormwater runoff and excessive groundwater infiltration, however, have in many
cases been entering and overloading sanitary sewers through deficiencies in the
sewer systems such as open pipe joints, cracked or broken pipes, leaking manholes,
and illegal connections (i.e., direct or indirect stormwater/groundwater connec-
tions to separate sanitary sewers). Sewer overloading arising from such deficiencies
may cause health hazards, financial losses, and inconvenience to area residents.
This occurs as a consequence of water pollution from treatment plant bypasses
and sewage overflows into streams, and also as a result of backups of sewage into
buildings and onto streets and yards. Excessive extraneous clearwater flows also
result in additional sewage treatment costs to the public. In order to remedy
and prevent these problems, it is the intent of this Article to set forth a
regionally applied program for the rehabilitation and correction of sanitary
sewer systems, and for the establishment of adequate long-term sewer management
programs by owners of separate sanitary sewers tributary to the MSDGC sewage
treatment facilities.
a. Scope and Goals. The purpose of this program is the removal of
groundwater infiltration and stormwater inflow (I/I) from separate sanitary
sewer systems in order to meet the following goals:
(1) Prevention of water pollution; and
(2) Elimination of basement sewage backups and other adverse
sewer surcharging conditions that cause health hazards
and financial losses.
Article 6-5 amended March 13, 1986, in its entirety.
Um
b. Applicability. This Article applies to all tributary communities
which own and/or operate a sanitary sewer system(s) which discharges directly
to the MSDGC system. As used herein, the term "tributary communities" shall
include municipalities, townships, private utility companies, school and sani-
tary districts, and any other permittee or entity. Tributary communities which
have been notified by the MSDGC as being in compliance with the MSDGC I/I re-
moval requirements need not undertake another sewer rehabilitation program and
are subject only to the requirement for the long-term maintenance and operation
program as specified in Item h, below.
C. Compliance Criteria.
(1) Each tributary community shall undertake a program for re-
moval of excessive I/I which meets all of the following
criteria.
(a) Average daily wet weather flow in the tributary
community's entire sanitary sewer system shall not
exceed 150 gpcpd, or optionally, documented water
usage plus allowable infiltration of 500 gallons
per inch diameter -mile per day; and
(b) Elimination of basement sewer backups and other
adverse sewer surcharging conditions that cause
health hazards and financial losses.
(2) However, each tributary community has the option of under-
taking an alternate I/I corrective action program (ICAP)
which meets all of the following criteria:
(a) The ICAP program shall be conducted pursuant to USEPA
regulations/guidance (40 CFR 35.2120, Construction
Grants 1985). All 1/1 that is determined to be
excessive by an acceptable cost effectiveness analysis
performed by the tributary community shall be elimi-
nated.(Also, see Item g, "Basin -by -Basin Analysis"
below.)
(b) Completion of such additional work as may be required
as a result of a Sewer System Compliance Conference
provided for in Item g(2), below. The additional work
may be required even after the elimination of the cost
effective I/I because the cumulative effect on the basin
of the remaining I/I from some of the tributary communi-
ties may continue to cause problems such as: raw sewage
bypasses to local waterways; inadequate treatment at plants
due to overloading; surcharging; basement sewage backups;
or in some cases one community's I/I causing adverse
effects on another community's ability to meet the goals
set forth in this ordinance.
(c) In order to participate in the ICAP option, tributary
communities must submit a formal resolution electing the
ICAP option on or before March 1, 1986.
19
d. Private Sources of I/I. A program for the correction of private
sources of I/I, which is compatible with the purpose of this Article and
meeting the compliance criteria, shall be initiated under either program option
selected in Item c above. Private sources are defined as cracked, broken or
open -jointed building service laterals; and illegal connections such as, roof
downspouts, storm sump pumps, area way drains, window well drains, exterior
stairwell drains, patio, yard and driveway drains, and footing/foundation drains
connected to the sanitary sewer system.
e. Semi-annual Reports. The MSDGC shall prepare and distribute semi-
annual status reports regarding progress by the communities on their I/I
identification and removal efforts. In order to complete this report, each
tributary community shall submit to the MSDGC semi-annual reports of its progress
and plans relative to its I/I identification and removal efforts. The first semi-
annual report shall be submitted to MSDGC on or before July 1, 1986. Reports
must be submitted regardless of the degree of progress made during the reporting
period.
f. Compliance Schedule. Each tributary community shall complete a series
of work items in accordance with the time frames set forth below. The work items
and schedule herein apply to both options set forth in item C above unless other-
wise indicated.
(1) Evaluation Sewer System.
(a) To the extent not already completed, each tributary community
pursuing the MSDGC Compliance Criteria in Item Cl, shall
undertake a study and evaluation of its sewer system, and
submit a completed evaluation study report to the MSDGC by
no later than January 1, 1987. The evaluation study shall be
in conformance with the MSDGC "Guidelines for Sewer Rehabili-
tation and Elimination of Extraneous Flows", April, 1985.
The work shall include flow measurements, physical survey of
the system, and, if determined necessary, rainfall simulation
(smoke testing and dyed water flooding), televising of sewers,
and identification of private sector I/I sources. All studies
must consider basement flooding, adverse surcharging, and
private sector I/I.
(b) If the ICAP option is chosen (Item c(2), a sewer system evalu-
ation survey (SSES) shall be conducted in accordance with USEPA
regulations and guidelines by no later than January 1, 1987. A
cost effectiveness analysis, prepared in accordance with
Appendix A of 40 CFR Section 35 as of July 1, 1984, shall be
performed as part of the SSES report. The cost information
for interceptors and sewage treatment facilities to be used in
the cost effectiveness analysis shall be furnished by the MSDGC
for the appropriate basins. Existing transport and treatment
capacity designed and intended for future population and develop-
ment cannot, for the purpose of cost effectiveness analysis and
planning, be used to accommodate excessive I/I. This existing
capacity is necessary for the continuing economic growth and
the vitality of the community which accrue by virtue of having
adequate sanitary infrastructure available to serve future
development. All sewer .system evaluation studies shall be re-
viewed by the MSDGC, and the MSDGC shall, if necessary, provide
the guidance required to achieve MSDGC approval.
20
(2) Design. Plans and specifications for the public sector
corrective work necessary to eliminate the deficiencies
identified in the above study shall be submitted to MSDGC
as soon as possible, but no later than January 1, 1988.
The plans for corrective work must include a timely and
reasonable implementation schedule and appropriate funding
arrangements. All designs, schedules and funding arrange-
ments will be subject to review and approval by the MSDGC
and, if necessary, by the IEPA.
(3) Corrective Actions. Corrective work necessary to eliminate
the deficiencies that have been identified shall be started
as soon as possible, but no later than July 1, 1988. All
corrective work must be completed in accordance with a
reasonable schedule which establishes a final completion
date and incorporates the private sector I/I removal program
plan and long-term operation and maintenance program. The
schedule will be based upon the mature of the corrective
work to be performed and the funding mechanism to be utilized.
Such Schedule will be formally codified in an enforceable
manner.
(4) Private Sector. A program plan for the correction of private
sector I/I sources shall be developed as soon as possible but
no later than January 1, 1988.
g. Basin -by -Basin Analysis. Analysis of each sewage treatment basin
shall be performed by the MSDGC as follows:
(1) After January 1, 1987, the MSDGC will conduct a basin -by -basin
analysis of the potential, cumulative effect on the corrective
actions, identified by the completed sewer system evaluation
studies as indicated in Item f(1) (a) and (b), above. This
analysis will utilize I/I removal projections to assess the
impact on transport and treatment capacities and may identify
continuing concerns relative to the goals in Item (a) above
that will necessitate consideration of further corrective actions
for particular basins or sub -basins which may apply to those
tributary communities undertaking the ICAP (cost effectiveness)
option.
(2) After July 1, 1988, the MSDGC will initiate action to address
any continuing concerns identified in Item g (1), above. A
"Sewer System Compliance Conference" shall be convened which
includes representatives of all the tributary communities identi-
fied as causing, contributing to, or being affected by the con-
tinuing concerns within each applicable basin. The IEPA and
USEPA will also be invited.
Each conference will discuss the nature of the continuing
concerns and formulate additional corrective actions and miti-
gation measures which may be required of tributary communities
undertaking the ICAP cost effectiveness option, As soon as
possible, but no later than one year after convening a conference,
a final compliance program and schedule will be adopted by the
MSDGC which will be applicable to the appropriate tributary
communities after completion of the corrective work in Item f,
above.
21
h. Long -Term Operation and Maintenance Program. All tributary
communities (including communities presently in compliance) must establish a
long-term operation and maintenance program with the aim of preventing entry
of I/I into their sewer systems.
i. Advisory Technical Panel. An ICAP Technical Panel will be estab-
lished by the MSDGC by January 1, 1986. This Panel will act in an advisory
capacity and will be composed of appropriate elected officials and other rep-
resentatives from the tributary communities, and the MSDGC. The Panel will
be given the following duties and assignments:
(1) develop, by March 1, 1986, recommendations regarding the
j. Evaluation of Impacts from Residual Flow. The MSDGC will plan for
and initiate a special study of the impacts of "residual" I/I remaining in the
separate sewer systems. This study will begin in the spring of 1987 and con-
tinue for the period of time necessary to adequately characterize the impacts in
areas where corrective actions have been implemented. The results of this
special study may be utilized for the Sewer System Compliance Conferences
convened pursuant to Item g (2).

gravity sewers. Discharge of force mains into another lift station is discouraged
and is considered to be potentially detrimental to the health and welfare of the pub-
lic served. Where a force main or a lift system is designed to discharge into another
lift station a detailed report is required to justify such design. The report should
include other methods considered, and the recommendation for the design must be
supported by engineering considerations. Written approval of the Owner of the
receiving lift station and a copy of the maintenance and operation agreement between
the parties must be furnished. The agreement shall also clearly specify the respon-
sibilities of the parties in case of failure of either lift station.
Where the project for which a'permit application is made consists of, or involves
a lift station and force main or lift system, submit the following:

approved by a Registered Professional Engineer acting in behalf of the Permittee
or the Owner of the project, or by the duly authorized representative of the
Professional Engineer.
No sewer trenches shall be backfilled except as authorized by the Inspection
Engineer after having inspected and approved the sewer installation. The In-
spection Engineer shall signify his approval and authorization for backfilling
on the Inspection Report. The Inspection Report shall be on the job site at all
times, and shall bear the signature of the Engineer, identifying those portions
of the sewer inspected and approved by him. The Inspection Report shall be made
available for review by the District representative.
4. "As -Constructed" Drawings. Within sixty (60) days after final inspection
and approval by the District, the Permittee shall furnish or cause to be furnished
to the District, a set of "As -Constructed" drawings. The pipe and joint materials
and applicable ASTM Specifications shall be indicated on the drawings.
Article 10. TESTING AND APPROVAL.
10-1. Requirement for Testing. All sewers constructed under permits issued
by the District shall be subject to inspection, testing and approval by the
District to insure compliance with the applicable requirements. All testing
shall be made, or caused to be made, by the Permittee or Co -Permittee at no
cost to the District and in the presence of the District Representative.
a. Testing procedures for polyvinyl chloride (PVC) pipe shall include
the following:
1, The project engineer shall randomly select portions of the
project to be deflection tested. Such portions shall consist
of the manhole intervals for the initial sewer construction up
to 1,200 linear feet and not less than 10% of the remainder of
the sewer project.
2. The 5% deflection test for pipe sizes six (6) to fifteen (15)
inches in diameter is to be run using a nine -arm mandrel having
a diameter equal to 95% of the base diameter of the pipe as es-
tablished in ASTM D-3034. For pipe sizes eighteen (18) to
twenty-seven (27) inches diameter, the nine -arm mandrel size
shall be 95% of the inside diameter as determined using the pipe
outside diameter and wall thickness dimensions shown in Table 1
of ASTM F-679, latest issue. The test shall be performed without
mechanical pulling devices.
3. The individual lines to be tested shall be so tested no sooner
than 30 days after they have been installed.
4. Wherever possible and practical, the testing shall initiate at
the downstream lines and proceed towards the upstream lines.
5. No pipe shall exceed a deflection of 5%.
6. In the event that the deflection exceeds the 5% limit in 10%
or more of the manhole intervals tested, the total sewer project
shall be tested.
7. Where deflection is found to be in excess of 5% of the original
pipe diameter, the contractor shall excavate to the point of ex-
cess deflection and carefully compact around the point where
excess deflection was found. The line shall then be retested for
deflection. However, should after the initial testing the de-
flected pipe fail to return to the original size (inside diameter)
the line shall be replaced.
10-2. Request for Final Inspection. Upon completion of construction, the Permittee
shall submit to the District a properly executed request for final inspection and
approval on the form prescribed by the District. No sewer shall be put in service
until it has been approved by the District, and until all the conditions of the permit
have been satisfactorily met.
Article 10-1 amended February 7, 1985

10-3• Construction Without Advance Notice. Construction without advance notice
to the District, as provided in Article 9-1, shall be considered prima facie evidence
that construction may not have been done in accordance with the applicable require-
ments. In addition to any other requirements, that portion of the newer construction
prior to the notification of the District shall be exposed by the owner, at his ex-
pense in at least one location between every two manholes, two terminal points or as
directed by the District for visual inspection by the District to insure compliance
with applicable requirements as to materials and workmanship.
10-4. Maximum Allowable Infiltration. It is the intent of the District that all
sewers within its territorial boundaries shall be construction of sound material and
shall be properly jointed so that the amount of ground water infiltration into the
sewer shall be kept at a minimum. The maximum allowable rate of infiltration or
exfiltration shall not exceed 200 gallons per twenty-four (24) hours per mile per
inch -diameter of the sewer pipe, for any section of the system and at any time during
its service life.

In Appendix A of this Ordinance.
Section 3. General Pretreatment Standards
("GPS")
General pretreatment standards and criteria for
discharges Into and pollution of sewerage
systems tributary to water reclamation facilities
of the Sanitary District, enacted by the Board of
Commissioners of the Sanitary District, are
contained in Appendix B of this Ordinance.
Section 4. Categorical Pretreatment Standards
("CPS")
Categorical pretreatment standards for
discharges into and pollution of sewerage
systems tributary to publicly owned treatment
works, promulgated by the United States
Environmental Protection Agency, are adopted by
the Board of Commissioners for discharges to
sewers under the jurisdiction of the Sanitary
District. Where there is a conflict in the applica-
tion of general pretreatment standards contained
in Appendix B and categorical pretreatment stan-
dards listed in Appendix C, the more stringent
standard shall apply.
Section 5. New or Increased Pollutant or Flow
No person shall introduce new or increased
flow volume, new or increased concentrations or
mass loadings of pollutants, changes in the
nature of pollutants, or changes in the point of
entry of flow or pollutants to the sewerage
syctems under the jurisdiction of the Sanitary
District which does not conform to the general
pretreatment standards, the categorical pretreat-
ment standards, or the information supplied in
reports to the Sanitary District as required in Arti-
cle V or Appendix C of this Ordinance unless such
person shall have notified the District in writing
thirty (30) days prior to commencement of such
discharge, and the General Superintendent has
not disapproved same in writing within said
30 -day notice period.
Section 6. Dangerous or Threatening Discharge
Notwithstanding any other remedies which the
Sanitary District may have by statute, common
law or this ordinance, when, in the determination
of the General Superintendent, any person's
discharge presents an imminent danger to the
public health, welfare or safety, presents or may
present an endangerment to the environment, or
which threatens to interfere with the operation of
the sewerage system or a water reclamation
facility under the jurisdiction of the Sanitary
District, the Sanitary District, acting through the
General Superintendent, shall apply to the Circuit
Court of Cook County for injunctive relief to cease
and desist the dangerous or threatening
discharge.
ARTICLE IV
Monitoring Methods and Facilities
Section 1. Compliance Determination
In order to determine whether or not the
sewage, industrial waste or other wastes
discharged by any person into any waters or
sewerage system conforms to the criteria or water
quality standards of the Sanitary District, the
Sanitary District may use any accepted engineer-
ing or scientific practice, method or device which
will lead to such a determination. When prac-
ticable, all measurements, tests and analyses of
the waters, sewage and wastes of any kind shall
be conducted in accordance with USEPA approv-
ed methods or, in the absence thereof, the latest
edition of Standard Methods.
Section 2. Control Manhole/Sampling Chamber
Each person subject to the terms of this
Ordinance shall install and maintain, at its own
expense, a control manhole or sampling chamber
for each separate discharge from the facility,
which shall have ample room in each control
manhole or sampling chamber to allow the
Sanitary District to perform inspections, sampl-
ing, and flow measurement operations. Each such
control manhole or sampling chamber shall be
safely and reasonably accessible to represen-
tatives of the Sanitary District and shall not be
bypassed nor obstructed by temporary or perma-
nent construction, manufacturing operations or
activities, landscaping, parked vehicles or any
other activities of the facility.
Section 3. Right of Access
Representatives of the Sanitary District may,
during reasonable hours of all working shifts of
the person, enter upon the premises of each per-
son subject to this Ordinance for the purpose of
installing, maintaining and inspecting measure-
ment or sampling devices or facilities, for conduc-
ting necessary measuring, gauging and sampling
operations, for inspecting or examining facilities,
premises, installations and processes, for inspec-
tion and copying of records, and for reviewing
pretreatment operating procedures and spill
prevention and control plans of such person to
determine compliance with this Ordinance or an
order of the Board of Commissioners adopted pur-
suant hereto.
Section 4. Monitoring for Public Hazards
Whenever the General Superintendent deter-
mines that a public safety hazard may exist in the
discharge from an industrial user to the sewerage
system under the jurisdiction of the Sanitary
District, the General Superintendent shall require
the industrial user to install suitable devices to
detect the presence of the hazardous materials in
the discharge and to notify the Sanitary Distict
immediately in the event of such hazardous
discharge.

ARTICLE VI
Administrative Proceedings
Section 1. Conciliation Process for
Compliance
Whenever the General Superintendent deter-
mines that sewage, industrial wastes, or other
wastes are being, have been, or may reasonably
be expected to be discharged into any waters or
the sewerage system under the jurisdiction of the
Sanitary District, which are not in compliance
with the provisions of this Ordinance, or that any
person has otherwise acted contrary to the provi-
sions of this Ordinance, the General Superinten-
dent or his designee shall first by conference,
conciliation or persuasion endeavor to the fullest
extent possible to eliminate or remedy such
violation.
Section 2. Compliance Reports
During conciliation proceedings, any person
may be required to furnish the Sanitary District
with interim and final progress com-
pliance reports and such other information as
is reasonably necessary to demonstrate com-
pliance with the applicable discharge stan-
dards of this Ordinance. All such reports, data,
and information, shall be executed by an authoriz-
ed representative of the person and certified as to
accuracy and completeness by a Registered Pro-
fessional Engineer.
Section 3. Proceedings for Show Cause/Board
Order Compliance
If the General Superintendent determines that
conciliation efforts have been unsuccessful, the
General Superintendent may order any person
who causes or allows pollution or such discharge
or engages in activities or conduct prohibited
hereunder to show cause before the Board of
Commissioners of the Sanitary District or its
designee why such pollution, discharge, or pro-
hibited activity or conduct should not be discon-
tinued. A notice shall be served on the offending
party, specifying the time and place of a hearing
to be held by the Board of Commissioners regar-
ding the violation, and directing the offending
party to show cause before the Board why an
order should not be entered directing the disconti-
nuance of such pollution, discharge or other pro-
hibited activity or conduct. The notice of the hear-
ing shall be served personally or by Registered or
Certified Mail at least ten (10) days before the
hearing; service may be had on any agent or
officer of a corporation or municipality. The Board
of Commissioners may, itself, conduct the hear-
ing and take the evidence, or may designate any
of its members or any officer or employee of the
District:
a. To issue in the name of the Board, notices of
hearings requesting the attendance and
testimony of witnesses and the production of
evidence relevant to any matter involved in
any such hearings;
b. To take the evidence; and
c. To transmit a report of the evidence and hear-
ing, including transcripts and other evidence,
together with recommendations to the Board
of Commissioners for action thereon.
At any public hearing, testimony taken before
the Board or any person designated by it must be
under oath and recorded stenographically. The
transcript so recorded will be made available to
any member of the public or any party to the hear-
ing upon payment of the usual charges therefor.
After the Board of Commissioners has reviewed
the evidence, it may issue an order to the party
responsible for the pollution, discharge, or other
prohibited activity or conduct, directing that
within a specified time period the pollution,
discharge or other prohibited activity or conduct
be discontinued unless adequate treatment
works, facilities or devices are properly operated
or that any other prohibited activity hereunder be
discontinued, and any other such orders as the
Board may deem necessary.
Section 4. Failure to Report is a Violation
Whenever a person subject to this Ordinance
fails to comply with any of the reporting
requirements of this Ordinance or with details
regarding reporting requirements as directed by
the General Superintendent, such failure shall be
a violation of the Ordinance. If It is necessary for
the Sanitary District to perform inspections
and/or sampling of the person's facility, the
Sanitary District may recover the costs of such
activity from the person in the same manner as
debts are recoverable at law.
ARTICLE VII
Court Proceedings
Section 1. Violation of Order to be Considered
a Nuisance
A violation of an Order of the Board of Commis-
sioners shall be considered a nuisance. If any per-
son causes or permits pollution to occur or
discharges sewage, industrial wastes or other
wastes into any waters or sewerage system under
the jurisdiction of the Sanitary District, or
engages in any other activity or conduct pro-
hibited by this Ordinance, or fails to comply with
any Order of the Board of Commissioners, the
Sanitary District, acting through the General
Superintendent, may commence an action or pro-
ceeding in the Circuit Court in and for the county
in which the Sanitary District is located or
operates facilities for the purpose of having the
pollution, discharge, or other prohibited activity
stopped either by mandamus or injunction.
Section 2. Penalties
Whoever fails to comply with any provisions of
this Ordinance, or with an Order of the Board of
Commissioners issued in pursuance of this
Ordinance, shall be fined not less than $100.00,
nor more than $1,000.00, for each offense. Each
day's continuance of such failure to comply shall
constitute a separate offense. The penalties so
imposed, plus reasonable attorney's fees, court
costs and other expenses of litigation, are
recoverable by the Sanitary District upon its suit,
as debts are recoverable at law.
Section 3. Injunctive Relief
In addition to the penalties provided in the
foregoing Section, whenever a person violates
any provision of this Ordinance or fails to comply
with any Order of the Board of Commissioners,
the Sanitary District, acting through the General
Superintendent, may apply to the Circuit Court of
Cook County for the issuance of an injunction
restraining the person violating the Ordinance or
tailing to comply with the Board Order from mak-
ing any further discharges into the waterways or
sewerage systems under the jurisdiction of the
District.

APPENDIX A
to the
SEWAGE AND WASTE CONTROL ORDINANCE
Discharges to and Pollution of Waters
Section 1. General Provisions
a. Dilution
Dilution of the effluent from a treatment
works or from any wastewater source is not
acceptable as a method of treatment of
wastes in order to meet the standards set
forth in this Appendix A. Rather, it shall be the
obligation of any person discharging con-
taminants of any kind to the waters of the
state to provide the best degree of treatment
of wastewater consistent with technological
feasibility, economic reasonableness and
sound engineering judgment. In making
determinations as to what kind of treatment
is the "best degree of treatment" within the
meaning of this paragraph, any person shall
consider the following:
(1) What degree of waste reduction can be
achieved by process change, improved
housekeeping, and recovery of individual
waste components for reuse; and
(2) Whether individual process wastewater
streams should be segregated or com-
bined.
In any case, measurement of contaminant
concentrations to determine compliance with
the effluent standards shall be made at the
point immediately following the final treat-
ment process and before mixture with other
waters, unless another point is designated by
the Sanitary District. If necessary, the con-
centrations so measured shall be recom-
puted to exclude the effect of any dilution
that is improper under this Appendix A.
b. Background Concentrations.
Because the effluent standards in this Appen-
dix A are based upon concentrations
achievable with conventional treatment
technology that is largely unaffected by or-
dinary levels of contaminants in intake water,
they are absolute standards that must be met
without subtracting background concentra.
tions. However, it is not the intent of these
regulations to require users to clean up con-
tamination caused essentially by upstream
sources or to require treatment when only
traces of contaminants are added to the
background. Compliance with the numerical
effluent standards is therefore not required
when effluent concentrations in excess of the
standards result entirely from influent con-
tamination, evaporation, and/orthe incidental
addition of traces of materials not utilized or
produced in the activity that is the source of
the waste.
c. Sampling
Except as otherwise specifically provided in
this Appendix A, proof of violation of the
numerical standards of this Appendix A shall
be on the basis of one or more of the follow-
ing standards:
(1) No monthly average shall exceed the
prescribed numerical standard.
(2) No daily composite shall exceed two
times the prescribed numerical standard.
(3) No grab sample shall exceed five times
the prescribed numerical standard.
d.Terminology
Terms used under Section 1c shall have the
following meanings:
(1)The monthly average shall be the
numerical average of all daily composites
taken during a calendar month. A monthly
average must be based on at least three
daily composites.
(2)A daily composite shall be the numerical
average of all grab samples, or the result
of analysis of a single sample formed by
combining all aliquots taken during a
calendar day. A daily composite must be
based on at least three grab samples or
three aliquots taken at different times.
(3)A grab sample is a sample taken at a
single time. Aliquots of a daily composite
are grab samples only if they are analyzed
separately.
Section 2. Violation of Water Quality
Standards
In addition to the other requirements of this
Appendix A, no effluent shall, alone or in com-
bination with other sources, cause a violation of
any state water quality standard. When the
Sanitary District finds that a discharge that would
comply with effluent standards contained in this
Appendix A would cause or is causing a violation
of state water quality standards, the Sanitary
District shall take appropriate action to require
the discharge to meet whatever effluent limits are
necessary to ensure compliance with the state
water quality standards. When such a violation is
caused by the cumulative effect of more than one
source, several sources may be joined in an
enforcement proceeding, and measures for
necessary effluent reductions will be determined
on the basis of technological feasibility,
economic reasonableness, and fairness to all
dischargers.
Section 3. Offensive Discharges
In addition to the other requirements of this
Appendix A, no effluent shall contain untreated
sewage constituents, settleable solids, floating
debris, visible oil, grease, scum, or sludge solids.
Color, odor and turbidity must be reduced to
below obvious levels.
Section 4. Deoxygenating Wastes
All effluents containing deoxygenating wastes
shall meet the following standards:
a. No effluent from any source discharging into
the Chicago River System or into the Calumet
River System shall exceed 20 mg/L of BOD or
25 mg/L of suspended solids.
b. No effluent whose dilution ratio is less than
five to one shall exceed 10 mg/L of BOD or 12
mg/L of suspended solids.
c. No effluent whose dilution ratio is less than
one to one shall exceed 4 mg/L of BOD or 5 mg/L
of suspended solids.
Section 5. Bacteria
No effluent governed by this Appendix A shall
exceed 400 fecal coliforms per 100 mL.
Section 8. Phosphorus
No effluent discharged to the Calumet River
shall contain more than 1.0 mg/L of phosphorus
as P.
Section 7. Lake Michigan
There shall be no discharge of any sewage,
Industrial wastes or other wastes of any kind Into
the waters of Lake Michigan.
Section 8. Additional Contaminants
The following levels of contaminants shall not
be exceeded by any discharge of sewage,
industrial wastes or other wastes to waters under
the jurisdiction of the Sanitary District:
