Combined Sewer NPDES Permit 03/12/2013Mount Prospect Public Works DepartmerIA INTEROFFICE MEMORANDUM The Illinois Environmental Protection Agency (IEPA), under the authority granted by the United States Environmental Protection Agency (USEPA), issued a National Pollutant Discharge Elimination System (NPDES) permit to the Village of Mount Prospect for the operation of its combined sewer overflow (CSO) structures. The National Pollutant Discharge Elimination System is a fundamental part of the 1972 Clean Water Act. Its purpose is to regulate the discharge of pollutants into the nation's waterways. Nationwide, over 400,000 distinct entities hold NPDES permits. Most of these permits are held by municipal storm sewer systems (MS4s), industrial (private) storm sewer systems, combined sewer systems, industrial and commercial facilities, and large-scale animal feeding operations. Every community that operates a combined sewer system, or a separate storm sewer system, must have an appropriate NPDES permit. The Village of Mount Prospect holds two (2) NPDES permits; one (1) for our storm sewer system (MS4), and one (1) for our combined sewer system. This memorandum, and the attached documents, pertains only to the combined sewer system NPDES permit. Information about the Village's storm sewer (MS4) NPDES permit, including the permit document, storm water management plan, and annual reports, can be found on the Village website (www.mountprospect.or ). The Village's combined sewer system is comprised of approximately 54 miles of sewer pipes ranging in size from 4" diameter to 90" diameter. Combined sewers are unique because they convey both sanitary wastewater and storm water in the same pipe. Combined sewers are commonplace in older communities including Boston, New York City, Philadelphia, Chicago, and most inner ring Chicago suburbs. Our combined sewer system generally serves the oldest part of the Village. Attachment A contains a map that depicts the area served by the Village-owned combined sewer system, the Village-owned separate sanitary sewer system, the Illinois American-owned separate sanitary sewer system, the Old Town Sanitary District separate sanitary sewer system. Key features of combined sewer systems, and the focus of the NPDES permit program, are the CSO structures that can discharge untreated combined sewer water into local streams. Our combined sewer system contains six (6) overflow structures. Four (4) structures can discharge to Weller Creek and two (2) can discharge to Feehanville Creek. Page 2 of 3 Public Meeting for Combined Sewer NPIDES Permit March 7, 2013 The graphic below depicts the layout of a CSO structure. Most of the time, the structure receives wastewater from the Village, and allows it to fall into a large interceptor sewer owned and operated by the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC). The MWRDGC interceptor then transports the wastewater for treatment at the North Side Wastewater Treatment Plant in Skokie, Illinois or the Kirie Wastewater Treatment Plan in Des Plaines, Illinois. During severe events, both the interceptor and Deep Tunnel can be filled to capacity. When this occurs, the CSO structures can discharge flow into adjacent waterways. Arguably, most of the water discharged into streams in this manner is storm water that does not need to be treated. However, it is also undeniable that at least a portion of the discharge contains Qnnitn %Ainctawntar The frim "innr wz TO wrp FROM VOMP > CSO CONTROL TO OUTFALL > STRVCTURE I J 1 1 Y of these discharges, the quality of water discharged, and the impacts on receiving streams are the focal points of the CSO NPIDES permitting system. The conditions of our CSO NPIDES permit stipulate that the Village complete a CSO Operations and Maintenance Plan, Pollution Prevention Plan and Public Notification Plan. The collective purpose of these documents is to demonstrate a strategy to comply with the nine minimum control measures contained in the National CSO Control Policy published in the Federal Register. The nine minimum control measures include: 1. Proper operation and regular maintenance programs for the sewer system and CSO outfalls. 2. Maximum use of the collection system for storage. 3. Review and modification of pretreatment requirements to ensure that CSO impacts are minimized. 4. Maximization of flow to wastewater treatment plants. 5. Elimination of CSOs during dry weather. 6. Control of solid and floatable materials in CSOs. 7. Pollution prevention programs to reduce containments in CSOs. 8. Public notification to ensure that the public receives adequate notification of CSO occurrences and CSO impacts. 9. Monitoring to effectively characterize CSO impacts and the efficacy of CSO controls. Page 3of3 Public Meeting for Combined Sewer NPDE8Permit March 7.2O13 *iur CSO NPIDES permit also requires us to introduce these plans at a public meeting and avail c-takeholders an opportunity to comment. To that end, I respectively request that this matter be added to the agenda for the March 12, 2013 Committee of the Whole meeting. Appropriate staff, along with our environmental consultant, Marcy Knyz of JFCardno New, will be in attendance to present the key components of these plans and facilitate pertinent discussion.

The NPDES permit allows the Village of Mount Prospect to operate and maintain combined sewer overflow (CSO) structures that have been constructed as part of its sewer system. 1.1 OBJECTIVES OF THE PLAN It is widely recognized that pollutants conveyed by surface runoff and other drainage sources can degrade the quality of surface waters,making them unsafe for drinking, fishing, swimming, and other purposes. In recognition of this situation the United States Environmental Protection Agency (USEPA),under the authority granted by the Clean Water Act, created a permit program entitled the National Pollutant Discharge Elimination System (NPDES) to identify and regulate such discharges. The Federal NPDES permit program is locally administered in the State of Illinois by the IEPA.The permit program is intended to control water pollution and improve water quality by regulating the discharge of pollutants from point sources into surface waters. Point sources includesewer pipe, culvert, and open ditch conveyance systems that route polluted drainage into waterways. NPDES permits are required for all industrial, municipal and other regulated facilities. In consideration of the risks to the environment presented by CSOs,the primary objective of this plan is to provide a program for effectively improving the Village’s CSOmanagement and thereby reducing likelihood for CSO events. The plan has been prepared to generally comply with the nine minimum control requirements of the NPDES permit by: 1.Implementing and maintaining a proper O&M program for sewer system and CSO outfalls; 2.Making maximum use of the collection system for storage of wet weather flows; 3.Reviewing and modifying pretreatment requirementsto ensure that CSO impacts are minimized; 4.Maximizing the volume of polluted waters processed and treated by the Publically OperatedTreatment Works (POTW); 5.Eliminating and preventing the discharge of dry weather flows from CSO structures to waterways; 6.Implementing controls to limit the solids and floatable materials in CSO discharges; 7.Implementing a pollution prevention program to reduce contaminants in CSO discharges; 8.Implementing a public notification program to ensure that the public receives adequate notification ofCSO event occurrences and impacts; and 9.Monitoring CSO events to effectively characterize CSO impacts and efficacy of CSO controls. ï File # 1301061.00 SECTION 2 -SEWER SYSTEM INFORMATION 2.1 WATERSHED AND DRAINAGE CHARACTERISTICS The Village of Mount Prospect is a Land Use Area by Zoning Classification northwest suburb of Chicago located in Cook County.

The existing Village combined sewer system covers approximately 2.47 square milesandwas constructed primarily in the 1940’s, 1950’s and 1960’s.However, portionsof the system were constructedas early as the 1920’s. Thepopulation of the Village grew from 1,720 in the 1940’s to 4,009 in the 1950’sto 18,906 in the 1960’s. When compared to the 2000 population of 56,265,the Village’s population has increased by roughly 3,000%since the 1940’s, 1,400% since the 1950’s, and 300%sincethe1960’s, with little recent expansion in extent or capacity of the storm sewers. This high rate ofpopulation growth equates to rapidinfrastructure growth within the Village in the form of new buildings, additional roads, parking lotsand general development.This infrastructure growth increased the total impervious (paved) area in the Village, thereby î File # 1301061.00 increasing the overall volume and peak flows of stormwater runoff. Consequently, certain areas of theVillage system are overtaxed, currently providing conveyance for up to ten times their original design capacity. 2.2 SEWER SYSTEM DESCRIPTION History of the Village’s Sewer System The early farmers settling the area organized specialized drainage districts to construct ditch and tile systems for the specific purpose of draining their fields following the area’s frequent heavy rains. The Weller Creek and Feehanville Creek drainage districts installed drainage tiles and excavated the creek channels to better drain their fields and minimize flooddamage. However, these early drainage systems were insufficient to serve the rapidly growing settlement. Consequently, one of the earliest tasks of the Village’s founding fathers was to commission the construction of a local sewer system. The local sewersystem serving early Mount Prospect was comprised entirely of combined sewers.Today, combined sewers constitute approximately 34% ofthe Village-owned sewer system(see Village of Mount Prospect Combined and Separate Sanitary Sewer Map,Appendix A-1). Starting inthe 1920s, both storm water and wastewater were conveyed using the same pipe. Initially, these pipes discharged both stormwater and sanitary wastewaterdirectlyinto area creeks. When the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) interceptor system was constructed, wastewater was transported to the treatment plant in Skokie. During rain events, stormwater and sanitary wastewater flows usually over-taxed the interceptor pipes and were discharged to the creeks. The MWRDGC interceptor system helped to reduce the amount of sanitary discharges in local waterways,but did not prove to be an effective solution, withhundreds of sanitary discharges still discharging to the creeks each year. Drenching rains in 1949, 1953 and 1955 prompted a flood study,which recommended the construction of relief sewers throughout the Village-owned sewer system. Unfortunately, the Village lacked the financial resources at the time to fund these improvements. To solve this problem, the Village deeded titleof its local combined sewer system to the MWRDGC in 1955. The MWRDGC issued $2 million in revenue bonds to finance the construction of a series of relief sewers in the Mount Prospect sewer system in 1955. The MWRDGC would retain ownership of the Village’slocal combined sewer system until the debt from the revenue bonds was retired in 1980. The relief sewers were large diameter pipes designed to fill during rain events. The pipes would temporarily store combined sewer flows during a storm surgeand release them to the interceptor sewers after the rain subsided.A series of 6relief sewers were constructed in Mount Prospect between 1955 and 1957. In total, 35,575 feet of pipes, ranging in size from 21” in diameter to 58” x 91”rectangular conduit, were installed.Similar relief sewers were constructed in other locations throughout the MWRDGC service area, since the flooding problemwas not unique to Mount Prospect. í File # 1301061.00 The goal of these relief sewer projects was Separate Combined Sanitary Storm to provide protection from a “5-year” SewerSewerSewer recurrence storm event.

The configuration of the tunnel system is shown at right. During an intense storm event, CSOsare directed into the tunnel and are stored until after the event. Pumping stations then dewater the tunnels and direct the water to identified water reclamation plants as capacity becomes available. Construction of the Phase1 tunnel systems began in 1975and portions of the tunnel system were in operation by 1985. By 2006, all of Phase 1 was completed and in operation. In total, the system contains 109.4 miles of large diameter deep rock tunnels that provide 2.3 billion gallons of storage volume to capture overflow. The total construction cost of all Phase I tunnels (Mainstream, Des Plaines, Calumetand O’Hare) was over $4.4 billion. Phase 1 of the TARP plan includes those improvements that impact the Village of Mount Prospect. Mount Prospect is served by the O’Hare tunnel. The O’Hare tunnel is comprised of 6.6 miles of pipe ranging in size from 9 feet to 20 feetin diameter at depths approaching 300 feet. It has the capacity to hold approximately 70 million gallons of combined sewer flows. Mount Prospect is directly served by the Majewski reservoir. This reservoir is located southwest of the Route 83 bridge overInterstate 90. This facility was completed in 1998 and has the capacity to store over 350 million gallons of combined sewer flow. It is dewatered and treated by the Kirie Wastewater ReclamationPlant on Oakton Street in Des Plaines. 2.4 WASTEWATER TREATMENT As mentioned previously, the Village of Mount Prospect wastewater collection system consists of both combined and separate sanitary sewer systems. These combined systems convey wastewater to MWRDGC interceptors and the TARP Facilities. Wastewater generated within the Village is ultimately treated at the MWRDGC Kirie WastewaterReclamationPlant in Des Plaines, Illinois. Mount Prospect wastewater can also be directed to the Northside Wastewater ë File # 1301061.00 Reclamation Plant located in Skokie, Illinois via the MWRDGC interceptor system. Completed in May 1980, the Kirie Plant is the MWRDGC’s newest facility. The Kirie Plant serves a predominantly residential area which includes Arlington Heights, Mount Prospect, Elk Grove Village, Prospect Heights, Wheeling, Buffalo Grove and parts of Rolling Meadows and Des Plaines. The KiriePlant has a design capacity of 72 million gallons of wastewater per day. Ithas its own tunnel and reservoir plan (TARP), which is independent of the Mainstream, Des Plaines and Calumet systems. The Kirie TARP is designed with the dual purpose of conveying dry weather flows to the plant and storing excess flows during rainstorms. During storm events in the Kirie TARP service area, flows that exceed the capacity of MWRDGC interceptors overflow into the O’Hare tunnel. Once the O’Hare tunnel is full, the Majewski TARPReservoir fills. When the Majewski TARP Reservoir fills to capacity, combined sewer overflows can occur,with wet weather flow being discharged directly into area waterways and tributaries including the Des Plaines River, the Chicago River, and ultimately, Lake Michigan. 2.5 CSO OUTFALL STRUCTURES CURRENT PERMITTED CSO FACILITIESVILLAGE OF MOUNT PROSPECT Stream CSO LocationLatitudeLongitudeReceiving Stream Classification No. 001Can-Dota AvenueGeneral Use 4203' 13" North8756' 47" WestWeller Creek 002Wa-Pella Avenue 4203' 13" North8756' 42" WestWeller CreekGeneral Use 003Elmhurst Road 4203' 18" North8756' 27" WestWeller CreekGeneral Use 004William St. Bridge 4203' 06" North8755' 42" WestWeller CreekGeneral Use 005Feehanville Rd/N of the Ditch 4204' 31" North8755' 20" WestFeehanvilleDitchGeneral Use 006Feehanville Rd/S of the Ditch 4204' 29" North8755' 19" WestFeehanville DitchGeneral Use By design, when the capacity of the combination sewer is exceeded a CSOevent will occur. The overflow is typically directed to surface waters through the CSOstructure. With the relief sewer capacityof 420 million gallonsprovided by the MWRD deep tunnel system, the likelihood for overflow events attributed to the Village of Mount Prospect sewer system is minimized. 2.6 MONITORING AND REPORTING OF CSO EVENTS In accordance with Special Conditions 10.11 and 14.11 of the North Side and Kirie NPDES Permit Numbers IL0028088 (effective March 1, 2002) and IL0047741 (effective August 1, 2004), the MWRD monitors the frequency and duration of the discharge from select, representative CSO outfalls authorized in the permits and for all other CSO outfalls connected to TARP, for which the MWRDhas the ability to monitor through an automated telemetry system. Through the monitoring process, the MWRD documents the frequency and duration of CSO events and the associated depth and duration for each rainfall event. The MWRD continues to monitor the CSO outfalls at all times unless the telemetry is out of service due to malfunction or routine maintenance. The results of the monitoring is submitted to the IEPA on a quarterly basis, andistypically scheduled to be transmitted onFebruary 15, May 15, August 15and November ê File # 1301061.00 15 of each year. Pursuant to the NPDES CSO Permit requirements, the Village is responsible for the reporting of all wet and dry weather overflow discharges. However, since the MWRD has installed telemetry equipment on all of the Village’s CSOs and is reporting monitoring data, detailing any overflows, directly to the IEPA on the Village’s behalf, the Village believes that the monitoring requirements of the NPDES permit have been satisfied. 2.7 PUBLIC NOTIFICATION PROGRAM Pursuant to the NPDES permit requirements, the Village is responsible for developing a program for notifying the public of any CSO discharges. The Village has developed a Public Notification Program that incorporatesthe MWRDGCs CCSOPublic Notification Plan. The program consists of a publication on the Village newsletter with background information on CSOs and directions to access the MWRDGC website for CSO occurrences.The MWRD maintains a networkof flow monitoring devices throughout the Chicago area to detect and automatically report the occurrence of CSOs. Members of the public are able to sign up to ). receive e-mail notification of CSO events by accessing the MWRD's website (www.mwrd.org These parties will be sent an email alert in the event of a known CSO or diversion to a surface waterway.Reference materials concerning the CSO monitoring program can be found on the MWRD's website using the following link:http://www.mwrd.org/irj/portal/anonymous/overview. The USEPAdeveloped water quality guidelines for the discharge of urban drainage into surface waterways and also developed the NPDES permit program to identify and regulate such drainage sources. Reference materials concerning the NPDES permit program, as well as information concerning CSOguidelines can be found on the USEPA website at the following location: http://cfpub.epa.gov/npdes/home.cfm. 2.8 MAXIMIZING STORAGE OF POLLUTANTSIN COMBINED SEWER SYSTEM The following is a summary of many of the Village’s efforts to maximize the storage of wastewater pollutants within the combined sewer system, or to minimize the flow of storm water into the combined sewer system, and thereby minimize the likelihood of CSO events. 1.Plan for the construction of relief sewer systems intended to provide additional storage for the combined sewer system. 2.Prohibit the connection of roof drainage and sump pumps drainage systems directly to the combined sewer system. The disconnection of existing downspout from the combined sewer system has been implemented where feasible. 3.Correct structural deficiencies in the combined sewer system (sewer mains, catch basins, manholes, etc.) and groundwater infiltration by reconstruction or through sewer lining projects. 4.Manhole and drainage structure replacement has been implemented as part of the capital projects or as part of system maintenance project to improve deteriorating manholes and minimize the flow of groundwater into structures. 5.The Village continues a program to regularly clean and inspect the combined sewer system, including sewer mains and catch basins, so that their capacity is undiminished by debris, sedimentand roots which can impede the flow in the sewers. é File # 1301061.00 6.Storm water management practice guidelines are being developed for public distribution in order to reduce the amount of storm water drainage entering the sewer system, to improve sediment controland to improve the quality of storm water runoff in the most cost effective manner. 2.9 POLLUTION PREVENTION Pursuant to the NPDES CSO permit requirements, the Village is responsible for creating a Pollution Prevention Plan. The Pollution Prevention Plan compliments this O&MPlan and provides more details about the Village’s efforts to prevent contaminants from entering into the combined sewer system. The following list identifies theactivities or services the Village provides to collect and remove various solid waste materials to keep pollutants and other debris from entering the Village’s combined sewer system.These activities and services reduce thepotential of dischargingany solid waste materialsinto Weller Creek, Feehanville Ditchand the Des Plaines River watershed. 1.Street sweeping/cleaning. 2.Catch basin/drainage structure cleaning. 3.Solid waste collection and disposal (refuse, recyclable, yard waste, bulk items). 4.Leaf collection and disposal. 2.10 ILLINOIS POLLUTION CONTROLBOARD The Illinois Pollution Control Board has not issued any orders or violations to the Village of Mount Prospect regarding itsCSO outfall structures. 2.11 SENSITIVE AREA CONSIDERATIONS The Village of Mount Prospect’sCSO outfall structuresdischarge to Weller Creek and Feehanville Ditch, which are tributaries to the Des Plaines River,which functions largely as a regional urban drainage waterway. The CSO does not discharge to sensitive areas such as wetlands,beaches, Outstanding Natural Resource Waters, National Marine Sanctuaries, shellfish beds, or to waters containing threatened or endangered species.Weller Creek, Feehanville Ditch and the downstream Des Plaines River are not used as a potable water source. è File # 1301061.00 SECTION 3 -MAINTENANCE 3.1 GENERAL MAINTENANCE OBJECTIVES The Village of Mount Prospect periodically conducts preventative maintenance of the combined sewer system to ensure proper operation during dry and wet weather flows. The Village recognizes that proper and regular maintenance of the combined sewer system effectively maximizes its conveyance and storage capacity.Maintenance can alsoreduce excessive inflow and/or infiltration into the system, help prevent basement sewer backups, mitigate adverse surcharging of the manholesand help reduce the volume of solids that is typically conveyed during the initial “first flush” associated with rainfall events. 3.2 STREET SWEEPINGAND LEAF COLLECTION The Village of Mount Prospect operates a street sweeper on a daily basis (weather permitting) from mid-March through mid-December. Under this program each street is scheduled to be cleaned on a bi-weekly cycle. During the Village’s leaf collection season,which runs from October 1 through November 16,property owners rake leaves into the street.The leaves are then removed from Village streets and hauled to a recycling site by the Department of Public Works. The removal is integrated with the sweepingoperations to ensure thorough cleaningand removal of leaves in a timely manner. 3.3 CATCH BASIN CLEANING The Village of Mount Prospect conducts cleaning operationsof surface drainage collection structures andcatch basins on a five-year cycle using vactor-type equipment. In those areas where sediment and debris is known to accumulatemore rapidly, cleaning is conducted seasonally. During periods of rainfall, particularly during the fall season, catch basin operation and surface flooding conditions are monitored and extra cleaning is conductedas necessaryto ensure proper operation. Material gathered during the cleaning process is regarded as landscape waste and is temporarily stored and conveyed to an appropriate landfill. 3.4 SEWER CLEANING TheVillage is grouped into 14 distinct geographic areas.These areas have both combined and separate sanitary basins.Each area has approximately the same amount of pipe and the same number of services (customers).The Village performs televising, cleaning and pipe condition assessmentoperationsin one area per year.Therefore, the Village assesses the entire combined sewer system on a 14-year cycle. Furthermore, the Village assesses the entire wastewater collection system (including both combined and separate sanitarysewers) on a14- year cycle. The cleaning of screening equipment after and during storms is completed by the MWRD, which regulates diversion and bypass devices. There are no screening or bypass devices included as part of the Village’scombined sewer system. ç File # 1301061.00 3.5 ROOT CUTTING Root cutting is performed on an as-needed basis. Sewers with a history of problems are serviced more frequently.If necessary, sewers with excessive root problems are treated with chemical root retardant, or linedor replaced as determined to be necessaryby the Director of Public Works. 3.6 SEWER REHABILITATION Sewer rehabilitation involves the replacement or lining of existing sewers based upon the findings of a televised inspection. The replacement methodologyis used to correct sewer segments with structural deficiencies or leakage problems. The lining methodology is applied where feasible to minimize surface disruption while improving functional capacity. Sewer lining preserves the structural integrity, reduces maintenance requirementsand improves flow capacity by eliminating root intrusion through joints and reducing friction losses along pipe walls due to its extremely smooth surface. The lining processconsists of pulling or invertinga resin- saturated, polyester felt tube into a designated segment of sewer. Hot water or steam is then pumped into the tube to cure the resin and form a tight-fitting, jointless and corrosion-resistant replacement pipewithin the original pipe. Service laterals are reconnectedby internally cutting openings at the catalogued service locations. The sewer is then inspected by a sewer televising system to verify that the liningprocesswas successful and that all service connections are restored. 3.7 MANHOLE REHABILITATION Manhole rehabilitation involves the replacement, repair, or lining of existing manholes. Replacement involves the excavation and removal of the defective manhole structure and the installation of a new precast concrete manholestructurethat meets current fabrication standards. Repair involves the removal or improvement of only a portion of the manhole structure,such as grade rings, cast iron frame and lid, and steps. Manhole lining extends the life of brick and block structures which are still structurally sound,but are exhibiting signs of distress that could eventually fail and require complete removal and replacement. Many manholes exhibit distress within the top 24 inches of the structure resulting fromclimatic conditions associated with repetitive freeze-thaw cycles and traffic loads. If a manhole exhibits distress at a depth greater than 24 inches, but is still structurally functional, then the full depth of the manhole is lined using either a cement or polyurea coating system. Manholes that are severely distressed or are within the boundary of a sewer replacement project are typically replaced. ïð File # 1301061.00 SECTION 4 -INSPECTIONS & MONITORING 4.1 MANHOLEINSPECTIONS All manholes are routinely inspected,and the results of the inspections are documented to develop work orders and budgets for programmed repairs.Inspections focus on structural as well as operational matters, including conditions affecting the manhole frame and lid, frame seal, grade rings, steps, walls, bench and trough, and pipe connections.The inspections also identify the sources of leakage, safetyand function to ensure proper operation and maintenance. 4.2 SEWER INSPECTIONS As previously stated, the Village is divided into 14 distinct geographic areas.The Village performs televising, cleaning and pipe condition assessment in one area each year.Therefore, the Village assesses the entire combined sewer system on a 14-year cycle. The structural and functional condition of the sewer mains and service connections are documented so that repairs can be scheduled and budgeted. The video recordingsof the televised inspection are retained by the Department of Public Works. The Village completed a combined sewer evaluation study in 2005 that assignedall the combined sewers a ratingfrom 1 to 5; 5 representing the worst condition and 1 representing the best condition.Subsequent to the evaluation, the Village launched a 10-year program to rehabilitate the worst sewer pipesat the pace of $1 million per year.Each year the Village contracts for CIPP liningsand spot pipe replacementstotaling $1 million.Naturally, all this work is televised as part of the inspection process. 4.3 OUTFALL STRUCTURE The CSO outfall structures are inspected on a monthly basis, and cleaned orrepaired as determined to be necessary by the Director of Public Works. 4.4 FLOW MONITORING Monitoringof the CSOstructures is conducted on a continuous basis by the MWRD. The record of CSO operation is transmitted to the MWRDoperations section and reported to the IEPA on a quarterly basis. The Village’sDepartment of Public Works conducts monthly visual inspections of the CSO to confirm function of the system. The Village also inspects the operation of the sewer system at designated manholes to confirm consistency of operation.If determined to be necessary, the Director of Public Works may retain the services of a specialist to conduct flow monitoring studies. 4.5 BUILDING INSPECTIONS Building inspections are done on a 14-year cycle. Buildings in combined sewer areas are inspected to make certain that sump pumps and downspouts are discharged at grade. ïï File # 1301061.00 4.6 REHABILITATION AND MAINTENANCE WORK The rehabilitation work determined to be necessary by the Director of Public Works as a result of the inspections and investigations is scheduled and budgeted as required. Rehabilitation methods employed reflect currentengineeringstandards, conventionsand regulations. 4.7 ELIMINATION OF DRY WEATHER OVERFLOWS The CSO systemfor the Village of Mount Prospectis configured such that the dry weather flows conveyed by the outlet sewer are intercepted by the dry weather interceptor maintained by the MWRD. Flow conveyed by the outlet sewer drops into a deep flow channel which is routed into the interceptor.The interceptor functionsas a weir device, in which flows must exceed the capacity of the intercepting sewer structure before reaching and passing through the outfall flood gates. This will only occur if the interceptor system capacity is exceeded,andisunable to receive additional flow from the outlet sewer. The flow monitoring devices installed by the MWRD are designed to identify suchdry weatherflows.In the unlikely event that a dry weather overflow occurs, the MWRD will alert the Village when the flow metering equipment records the overflow condition. In the event a dry weather overflow is documented and observed byVillage staff, the Village will notify the IEPA and implement corrective actionsto prevent the overflows. ïî File # 1301061.00 SECTION 5 -OTHERCSO PERMIT EFFORTS 5.1 RECORD KEEPING TheDepartment of Public Works maintains records of work orders routinely issued in the process of repairing collapsed and blocked sewers, investigating basement backups, street flooding, collection system complaintsand excess flow levels at combined sewer overflows. The records and documentation aregenerally used to aid planning for future maintenance work. 5.2 SEWER SYSTEM MAPPING The Village maintains both an electronic and printed mapof its sewer system, detailing the configuration of thecombined sewer, sanitary sewerand storm sewer systems. The sewer system map generally displays the inventory of the entire sewer system, showing a record of measured elevations and pipe lengths andsizes.The map is updated on a periodic basis to reflect changes to the sewer system fromsewer system improvements,and to add content as new information becomes available. Printed copies of the latest version of the map are distributed to Village staff as determined to be requiredby the Director of Public Worksto support maintenance operations. 5.3 PROCEDURES FOR LAND DEVELOPMENT The Village of Mount Prospect issues building permits for land development projects following approvalby the MWRD in compliance with its Sewer Permit Ordinance, or as otherwise determined to be appropriate by local code and standards. ïí File # 1301061.00 Appendix A-1 Ê×ÔÔßÙÛ ÑÚ ÓÑËÒÌ ÐÎÑÍÐÛÝÌ ò Ô»¹»²¼ ÝÑÓÞ×ÒÛÜ ÍÛÉÛÎ ÞßÍ×Ò ÍÛÐßÎßÌÛ ÍßÒ×ÌßÎÇ ÍÛÉÛÎ ÞßÍ×Ò ÑÔÜ ÌÑÉÒ ÍßÒ×ÌßÎÇ Ü×ÍÌÎ×ÝÌ

The primary objective of this program is to inform the public in the event of combined sewer overflows. The Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) has flow monitoring equipment installed at representative locations throughout its service area, including the CSO control structuresto which Mount Prospect’s CSOs are tributary. In addition, the MWRDGChas created a public notification programthat includes signage at the outfalls, a web page to inform the public of CSO occurrences, and an email address book for the sending of CSO notifications to interested parties. In the interest of avoiding a redundancy of efforts, the MWRDGChas invited TARP municipalities to use the MWRDGCPublic Notification Programfor their public notification compliance. The Village of Mount Prospecthas accepted the MWRDGCoffer and taken the following actions: 1.Provided the web address of the MWRDGCCSO web page to Village residents on the Village’s website. 2.Installed signage, adhering to the MWRDGCdeveloped model, at the Village owned outfalls. 3.Signed on to the MWRDGCCSO email notification such that the Village’s Director of Public Works, Deputy Director of Public Works and Water/Sewer Superintendent will be alerted to any combined sewer overflows. ï File # 1301061.00
