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)2 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. Amended 10/26/72 2 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 effect, 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" 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. 3 Article 2.'

Drop Manholes. An exterior drop pipe should be provided for a sewer enter- ing a manhole at an elevation of 24 inches or more above the manhole invert, as provided in the rules and regulations of the Illinois Sanitary Water Board. The minimum diameter of a drop manhole shall be 48 inches. The diameter of the drop pipe shall preferably be larger than, or of the same diameter as, the entering sewer. The minimum diameter of the drop pipe shall not be smaller than the dia- meter of the entering sewer by more than two nominal diameters (e. g, for 12", 15" and 18" entering sewer, the drop shall be 8", 10" and 12" respectively), pro- vided that the minimum diameter of the drop pipe shall not be less than 8". If a smaller drop is desired, design calculations and configurations shall be submitted for review and approval. 5. 3-4. Protection of Water Mains. Water mains shall be protected in accordance with the requirements of the Illinois Sanitary Water Board. Where a sewer main lateral or building service sewer crosses a water main, a minimum vertical sepa- ration of 18" shall be provided between the top of the lower pipe and the bottom of the upper pipe. Where the 18" vertical separation is not provided, the sewer shall be constructed of cast iron or ductile iron pipe or shall be encased in concrete for a minimum distance of 10 feet on each side of the water main. 3-5. Materials. All materials shall conform to the applicable ASTM, ASA or other national or accepted standards. When the materials indicated below are specified by the design engineer, the pipe joints shall conform to the specifications shown, for sanitary sewer work in separate areas and for all sewer work in com- bined areas; Material Joint a. Vitrified Clay Pipe ASTM C-425 b. Concrete Sewer Pipe. ASTM C-443 C. Asbejtos Cement Pipe ASTM D-1869 d. Truss Pipe (ABS Pipe) ASTM D-2680 e. Cast Iron Pipe ASA A 2 1. 11 f. Ductile Iron Pipe ASA A 21.11 Nothing contained in this Article shall be interpreted to mean nor imply an endorse- ment by the Metropolitan Sanitary District of any material over another, 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 con- struction of any sewers within the District shall not be less stringent than the "Stan- dard Specifications for Water and Sewer Main Construction in Illinois" (The Red Book), adopted by a joint committee of the Illinois Society of Professional Engineers, Consulting Engineers Council of Illinois, Illinois Chapter of The American Public Works Association, Illinois Municipal League and The Associated General Contrac- tors of Illinois. A copy of said specifications is obtainable from the organizations mentioned. 3-7. Design FIow. Average design flow for sanitary sewer shall be 100 gpcpd. Maxi- mum design flow for sanitary sewer lines shall be determined by one of the equations indicated below; provided, however, that the maximum design flow for sewer laterals need not exceed 400 gpcpd and the maximum design flow for sewer mains and trunks shall not be less than 250 gpcpd. Equation 1. Q = 500 (P)VS Equation 2. Q =100 (I + 14�� 4+ Vr ) "Where Q = Maximum design flow, gpcpd P = Population in thousands 6. 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 per- mit the construction of curvilinear sewer, it is mandatory that available mainte- nance 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. Ali%nment: 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. 7. Article 4. 'SUPPLEMENTAL DESIGN REQUIREMENTS. 4-1. Overhead Plumbing, After December 31, 1970, all new buildings with base- 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:0. OOC. 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, pea gravel, crushed stone or crushed slag, 1/4" to 3/4" in size. As a minimum, the material shall conform to the requirements of Article 704. Ol 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 7, CA 8, 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 minimum thickness equal to 1/4th of the outside diameter of the sewer pipe but shall not be less than four inches (4"). 4-4. Building Service Sewer. Building service sewer is defined as a sewer pipe receiving 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. Minimum design standards, and other requirements 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 required 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. Amended 3-25-71 8. 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 flows, are not considered inspection man- hole s. 4-7. Sound Engineering Practice.

No permit will be issued for sewer construction within any municipality lying totally or partially within a flood plain, unless the municipality shall have adopted a Flood Plain Ordinance which has been filed with, and approved by the District as to minimum requirements for the protection of the health and wel- fare of the public. 5-2. Conformance with Flood Plain Ordinance. All projects constructed within a flood plain area shall conform to the requirements of the Flood Plain Ordinance adopted by the local government having jurisdiction over the area in which the pro- ject is located. Among other requirements, the local ordinances generally provide that manholes within the flood plain must have a rim elevation 30" above the flood crest elevation or must be provided with watertight, lock -type covers, and shall not be lower than the flood crest elevation. 5-3. Limits of Flood Plain. The flood crest elevation and the limits of the flood plain shall be as established by the local Flood Plain Ordinance based on the USGS maps. The portion of the project lying within the flood plain shall be delineated and the limits of the flood plain shall be clearly indicated on the overall plan. 10. 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. Amended 3-25-71 it. e. Floor Drains. Floor drains in basements shall 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.

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 and 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 Control Ordinance acceptable to the District, and has on file with the District, an approved drainage plan and schedule for its implementation, or (2) The permittee or co -permittee provide detention of storm water runoff as set forth in the following criteria. (1) Allowable Release Rate. The release rate of storm water from all developments requiring detention shall not exceed the storm water runoff from the area in its natural undeveloped state. Because of the flat conditions of the land in this area, channel configurations cut by nature are generally unable to handle the runoff from high intensity rainfalls and results in flood plain storage or spreading of runoff over the land areas during the larger storm periods. In order not to increase the runoff from such areas after Amended 5/27/71,10/26/72, 4/17/75 13. 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 14. *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 acquiree 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. '-Amended 4-17-75; Effective Date: July 1, 1975 15. (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 5% 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 16. 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 requirements 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 In order to reduce overloading of separate sanitary sewers by eliminating illegal connections and other deficiencies, the following requirements shall be observed: a. Within one year of the effective date of this amendment, all permittees in separate sewered areas outside the City of Chicago shall inspect all structures within their jurisdiction or control and ascertain whether any downspouts or roof drains are connected directly or indirectly to sanitary sewers. Any such illegal connections shall be corrected by causing such downspouts to discharge to the ground, or to authorized storm sewers, wet wells or ditches. Such legal action as may be required to the effect the necessary corrections shall be the responsibility of the appropriate permittee. b. Within one year of the effective date of this amendment, all permittees having jurisdiction over separate sanitary sewer systems shall visually inspect said systems to ascertain the location of sources of storm water entry to the systems, such as (but not limited to) (1) leaking manholes, manholes having open grates or loose frames, or manholes located in low points or ditches; (2) failure to install lock -type, watertight manhole frames and lids in flood hazard areas; (3) cracked or broken pipes at manholes; (4) illegal storm water inlets or connections; (5) problems at creek or ditch crossings or at points of storm sewer cross -connections and overflows. Such permittees shall also make inspections during dry and wet weather periods for purposes of comparison to determine points of storm water entry into their systems. Any sources of storm water entry to the sanitary sewer systems discovered in the course of said inspections shall be repaired and corrected, including such steps as may be necessary to remove footing drains, areaway drains, window well drains, and other illegal connections of storm water sources to the sanitary sewer systems. Such legal action as may be required to effect the necessary corrections shall be the responsibility of the appropriate permittee. "Effective January 1, 1973 Amended 10-26-72 17. c. Quarterly reports of the inspections required under Subparagraphs 6-5a and 6-5b, above, shall be submitted to the District by or on behalf of said permittees, beginning within three months of the effective date of this amendment, and said reports shall certify to the facts found in such inspections, and to any action taken to correct the illegal connections or other problems that may have been found. d. Nothing herein shall impair the power or authority of the District itself to take such legal action as it deems necessary to accomplish the required inspection of separate sanitary sewer systems, or the elimination of illegal connections and other deficiencies. e. The period of one year indicated above, may be extended by the Chief Engineer for an additional period not to exceed one year upon presentation of evidence of satisfactory progress and evidence that such extension is justifiable. Extension beyond a period of two years shall not be granted, except after hearing by the Board. 18. SECTION III - SUBMITTAL REQUIREMENTS Article 7. PROCEDURES FOR SUBMITTALS. 7-1.

(See Article 7-1) b. Contract drawings. C. Design criteria and calculations. d. Required maintenance bond. 8-6. Lift Stations. Gravity sewers are by far preferable to Lift Stations and force mains as a means for conveying sewage. In general, lift stations are not desirable nor recommended and should be resorted to only after all other engineering studies have been exhausted. Force mains should preferably be designed to discharge into 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: a. Pe rmit form, location map and other relevant data as may be required. (See Article 7-1) b. Contract drawings. C. Plan and profile of force main. d. Design calculations and alternate power available. (Complete special MSD form for this purpose. ) e. Map of area to be served, clearly delineated. 2 3. SECTION IV - CONSTRUCTION, TESTING AND APPROVAL Article 9. CONSTRUCTION AND INSPECTION 9-1.
