The statutory authority for this Ordinance is contained in 55 ILCS 5/5-1062.1, 70 ILCS 2605/1 et seq., and particularly 70 ILCS 2605/7f, 70 ILCS 2605/7h, 70 ILCS 2605/12, as well as other applicable authority, all as amended from time to time. 3. An authorized municipality, as defined in Article 14 of this Ordinance, may adopt this Ordinance pursuant to its authority to adopt ordinances regulating floodplain and stormwater management and governing the location, width, course, and release rate of all stormwater runoff channels, streams, and basins in the authorized municipality, over which the authorized municipality has jurisdiction. The statutory authority for an authorized municipality to adopt this Ordinance is contained in the Illinois Municipal Code, 65 ILCS 5/1 et seq., as well as other applicable authority, all as amended from time to time. § 101. Cook County Stormwater Management Plan The District's Board of Commissioners adopted the CCSMP on February 15, 2007. This Ordinance is a component of the countywide stormwater management program presented in the CCSMP. Other components of the countywide stormwater management program include the development of Detailed Watershed Plans (DWPs) for the major watersheds of Cook County. The CCSMP and DWPs are available on the District's website, www.mwrd.org. § 102. Considerations The District has considered numerous factors in the creation of this Ordinance including but not limited to: 1. Inappropriate floodplain uses and development have increased flood risk, flood damage, and environmental degradation; ARTICLE 1. AUTHORITY AND PURPOSE Page 1-1 7/10/14 2. It is necessary to consider stormwater management on a watershed basis; 3. Cook County lands drain poorly due to generally flat topography and soils of low permeability; 4. Many land development practices alter the natural hydrologic balance of Cook County streams; 5. Wetlands play an essential role in flood storage, floodplain management, sediment control, and water quality enhancement; 6. Riparian environments may be effective in reducing flow rates and volumes in addition to providing stream bank erosion protection and water quality enhancements; 7. Many stormwater facilities are not adequately maintained; 8. While the District has required stormwater detention in separate sewer areas since 1972 via the Sewer Permit Ordinance, flooding continues to be a concern in Cook County due to the increased volume and rate of stormwater runoff resulting from continued development; 9. Stormwater detention requirements for new developments alone do not address the impacts of transportation and other improvements; and 10. Infiltration and inflow contributes to basement backups, sanitary sewer overflows, and excessive flows to the District's water reclamation facilities. § 103. Purposes of this Ordinance The purpose of this Ordinance is to effectuate the purposes and intent of the Metropolitan Water Reclamation District Act (70 ILCS 2605/1 et seq.) by: 1. Protecting the public health, safety, and welfare, and reducing the potential for loss of property due to flood damage; 2. Managing and mitigating the effects of urbanization on stormwater drainage throughout Cook County; 3. Protecting existing and new development by minimizing the increase of stormwater runoff volume beyond that experienced under existing conditions and by reducing peak stormwater flows; 4. Promoting responsible land use practices in Cook County, particularly within floodplains and floodways; ARTICLE 1. AUTHORITY AND PURPOSE Page 1-2 7/10/14 5. Protecting existing water resources, including lakes, streams, floodplains,wetlands, and groundwater from detrimental and unnecessary modification in order to maintain their beneficial functions; 6. Reducing or mitigating the environmentally detrimental effects of existing and future runoff in order to improve and maintain water quality; 7. Preserving and enhancing existing riparian environments; 8. Controlling erosion and the discharge of sediment from all sources including, but not limited to, stormwater facilities, waterways, developments, and construction sites; 9. Requiring appropriate and adequate provisions for site runoff control; 10. Requiring consistency in stormwater management activities within and among the units of government having stormwater management jurisdiction; 11. Ensuring future development in the floodplain does not adversely affect floodplain environments or increase the potential for flood damage; 12. Requiring regular, planned maintenance of stormwater management facilities; 13. Encouraging control of stormwater quantity and quality at the most site-specific or local level; 14. Establishing uniform and minimum countywide stormwater management regulations while recognizing and coordinating with stormwater programs effectively operating within Cook County; 15. Requiring strict compliance with and enforcement of this Ordinance; 16. Meeting the floodway permitting requirements of the Illinois Department of Natural Resources, Office of Water Resources, delineated in the Rivers, Lakes, and Streams Act (615 ILCS 5/18g); 17. Complying with the rules and regulations of the National Flood Insurance Program (NFIP)thereby making federally subsidized flood insurance available; 18. Protecting the ability of the District's sewerage systems, intercepting sewers,TARP structures, sewage disposal and treatment plants, works and facilities to perform the functions for which they were designed; 19. Controlling the nature, volume, and manner of discharge into the District's sewerage systems, intercepting sewers, TARP structures, sewage disposal and treatment plants, works, and facilities; ARTICLE 1. AUTHORITY AND PURPOSE Page 1-3 7/10/14 20. Maintaining stable operation of the District's sewerage systems, intercepting sewers, TARP structures, sewage disposal and treatment plants, works, and facilities; 21. Reducing infiltration and inflow into the District's sewerage systems, intercepting sewers,TARP structures, sewage disposal and treatment plants, works, and facilities; and 22. Protecting waters within Cook County so as to preserve the public health. § 104. Relationship to the Sewer Permit Ordinance and Manual of Procedures 1.

Allowances for Redevelopment and Development Subject to Legacy Sewerage System Permits 1. For redevelopment of a site tributary to an existing detention facility that will only require a marginal increase in the new total storage required in the same existing detention facility, the increase in storage may be waived if the following conditions are met: A. Actual storage volume is verified to meet or exceed the required detention volume based on a recent survey, signed and sealed by either a Professional Engineer or Professional Land Surveyor; and B. The marginal increase in incremental required storage volume is less than one- tenth (0.10) of an acre-foot or within two percent (2%) of the existing total storage. 2. Incidental disturbance to an existing detention facility to provide the new required additional detention volume may be considered non-qualified development. 3. Allowances noted below may be granted for the redevelopment of a parcel that was planned to be tributary or contains within the parcel an existing detention facility permitted under a sewerage system permit: A. If the redevelopment meets all of the following conditions: (1) The design of the existing detention facility is documented and approved under an existing sewerage system permit (commonly referred to as Schedule D); (2) Actual storage volume is verified (or is further modified as part of the current work)to meet or exceed the required detention volume under the permit based on a recent survey, signed and sealed by either a Professional Engineer or Professional Land Surveyor; ARTICLE 5. REQUIREMENTS FOR STORMWATER MANAGEMENT Page 5-14 7/10/14 (3) The redevelopment provides treatment of the volume control storage as required in §503 of this Ordinance; and (4) The redevelopment provides adequate capacity to convey stormwater runoff to the existing detention facility for all storms up to and including the 100-year storm event; B. Then, the following redevelopment allowances may be granted: (1) If the redevelopment's composite runoff coefficient does not exceed the design composite runoff coefficient of the existing detention facility as designed and intended under the original permit, additional stormwater detention volume is not required; (2) If the redevelopment's composite runoff coefficient exceeds the design composite runoff coefficient of the existing detention facility as designed and intended under the original permit, additional stormwater detention volume shall be provided for the redevelopment. In such situations, the modified rational method using Bulletin 70 rainfall data may be used to calculate the additional required storage volume. The release rate for the redevelopment will be based as follows: (a) For redevelopment of areas within a permitted parcel intended to be tributary to an existing detention facility,the existing approved release rate and restrictor may be retained; (b) For redevelopment of areas within a permitted parcel that was never intended to be tributary to an existing detention facility, but will become tributary to such detention facility upon redevelopment, the original release rate for the basin will be recalculated based on a pro-rated area amount. The total new required storage volume will be updated based on the new required release rate and the restrictor may need to be replaced. C. For redevelopment of a parcel never planned to be tributary or that does not contain an existing detention facility permitted under a sewerage system permit,the redevelopment shall be subject to the standard stormwater management requirements described in §500 through §504 of this Ordinance. 4. Allowances noted below may be granted for the redevelopment of a parcel that contains a detention facility within the parcel that was never permitted under a sewerage system permit: A. If the redevelopment meets all of the following conditions: ARTICLE 5. REQUIREMENTS FOR STORMWATER MANAGEMENT Page 5-15 7/10/14 (1) Actual detention volume is verified (or is further modified as part of the current work)to meet or exceed the detention volume calculated according to the standards set under the Legacy Sewer Permit Ordinance, and signed and sealed by either a Professional Engineer or Professional Land Surveyor; (2) Actual release rate from the existing control structure is verified (or is further modified as part of the current work) to be less than the requirements set under the Legacy Sewer Permit Ordinance, and the calculations are signed and sealed by a Professional Engineer; (3) The redevelopment provides treatment of the volume control storage as required in §503 of this Ordinance; and (4) The redevelopment provides adequate capacity to convey stormwater runoff to the detention facility for all storms up to and including the 100- year storm event. B. Then,the following redevelopment allowances may be granted: (1) If the redevelopment's proposed impervious area does not exceed the existing or anticipated impervious area, additional stormwater detention volume is not required; (2) If the redevelopment's proposed impervious area exceeds the existing or anticipated impervious area, additional stormwater detention volume shall be provided for the redevelopment. In such situations,the modified rational method using Bulletin 70 rainfall data may be used to calculate the additional required storage volume. The release rate for the redevelopment will be based on a pro-rata share of redevelopment's portion of the actual release rate of the control structure. ARTICLE 5.

REQUIREMENTS FOR SEWER CONSTRUCTION Page 7-12 7/10/14 ARTICLE 8. INFILTRATION / INFLOW CONTROL PROGRAM § 800. Introduction The separate sanitary sewers within the District's service area are 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 connections to separate sanitary sewers). Sewer overloading arising from such deficiencies may cause health hazards, financial losses, and inconvenience to area residents. These detrimental conditions occur 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 clear water flows also result in additional sewage treatment costs to the public. Since the enactment of the 1985 Sewer Summit Agreement (SSA), many communities have invested in rehabilitation efforts yet the sewer systems still have excessive stormwater inflow and groundwater infiltration (I/I) requiring further reduction. Many communities still need to establish on-going maintenance programs and budgets that continually renew local systems. The Illinois Environmental Protection Agency (IEPA)has imposed a special condition as part of the District's National Pollutant Discharge Elimination System (NPDES) Permits that requires the owners and/or operators of separate sanitary sewer systems that discharges directly and/or indirectly to the District's facilities (satellite entities) to implement measures in addition to those required under the SSA if excessive I/I causes or contributes to sanitary sewer overflows (SSOs) and/or basement backups (BBs). In order to address the requirements set forth in the NPDES Permits and other federal, state and local regulations, it is the intent of this Article to set forth a regionally applied Infiltration/Inflow Control Program (Program) for the rehabilitation and correction of sanitary sewer system deficiencies, and for the continuation of adequate long-term sanitary sewer management and maintenance programs by the satellite entities that are tributary to the District's facilities. § 801. Scope and Goals 1. The purpose of this Program is to provide a framework for asset management of separate sanitary sewer systems to meet the following goals: A. Maintain infrastructure to prevent sanitary sewer overflows and basement backups due to sewer surcharging and other adverse sewer system conditions. B. Comply with the District's NPDES Permits and all other applicable federal, state, and local laws and regulations. C. Minimize extraneous flows transported to the District's facilities due to defective system components or illegal connections. ARTICLE 8. INFILTRATION/INFLOW CONTROL PROGRAM PAGE 8-1 7/10/14 § 802.
