P:110800s110870s1108761108760561Reports Sanitary Sewer Evaluation City of Riverdale, Iowa EXECUTIVE SUMMARY Basis for Sanitary Sewer Evaluation: The intergovernmental agreement that provides for the construction and joint use of sanitary sewers and sewage disposal facilities, dated January 5, 1974, is the basis for operating, maintaining, and financing the common plant and system assets. Furthermore, this intergovernmental agreement established Davenport, Bettendorf, Riverdale, and Panorama Park as Joint Use Cities. The construction permit for the Davenport Water Pollution Control Plant was issued on March 15, 1974. This plant was designed to receive 40 million gallons per day (MGD) of flow during wet weather. The plant historically receives wet weather flows in volumes that far exceed this design capacity. These excessive flows result in the discharge of untreated wastewater from the collection system. The administrative consent order, dated about March 14, 2013, between the Joint Use Cities and the Iowa Department of Natural Resources established a schedule for necessary upgrades to the wastewater collection systems. The intent of the administrative consent order is to eliminate the discharge of untreated wastewater from the collection system. The administrative consent order established the date of July 1, 2018 that all Joint Use Cities shall undertake the study and action to remove inflow and infiltration sources from the Interceptor Sewers. Evaluation Methods: On October 15, 2018, the City of Riverdale entered into an agreement with MSA to evaluate certain specific sanitary sewers within the City limits. In that agreement, MSA agreed to provide smoke testing to review conditions for possible surface water inflows into the certain sanitary sewers. Furthermore, MSA agreed to arrange for the televising of certain sanitary sewers to be performed by the City of Bettendorf. A summary of the sanitary sewers to be evaluated specifically included those that are relatively near surface bodies of water. The rationale was that these sewers may have a greater likelihood of contributing surface water inflow and groundwater infiltration into the sanitary sewer system, than those sewers that are on higher ground away from known water sources. These sanitary sewers include those that are located in Havens Acres, those along Bellingham Road, those along Fenno Road and Fenno Drive, and those that are along the tributary to Crow Creek on Scott Community College property.

P:110800s110870s1108761108760561Reports Sanitary Sewer Evaluation City of Riverdale, Iowa All of these aforementioned sanitary sewers were smoke tested by MSA. Because of off -road conditions and cost constraints, only the sanitary sewers in Havens Acres, along Bellingham Road, and those along Fenno Drive and Fenno Road were televised. The results of the investigations (i.e. smoke testing and reviewing televising video) indicated the sanitary sewer system has multiple defects. Because the reason for this study is the administrative consent order, the focus of MSA's recommendations is the elimination of surface water inflows and groundwater infiltration into the sanitary sewer system. MSA rated the sanitary sewers relative to these water issues, placing an emphasis on removing known sources of inflow and infiltration. The result of MSA's investigation, evaluation, and rating is summarized with Figure 1— Sanitary Sewer Priority Rating Map. Figure 1 establishes a priority system for the City of Riverdale to address inflow and infiltration concerns. Page ii © February 2019 MSA Professional Services, Inc..

Study Location Riverdale is located in Scott County, Iowa, centrally located in eastern Iowa. It is located within the Quad Cities area (Rock Island, IL, Moline, IL, Bettendorf, IA, and Davenport, IA.) The population of Riverdale, based on the most recent census data (2010), is 405 people. Riverdale owns sanitary sewers that serve both their own residents, as well as sanitary sewers that convey sanitary sewage from the surrounding City of Bettendorf. MSA recommended, for this first phase of a sanitary sewer investigation of inflow and infiltration (I/I) problems, the evaluation of those sanitary sewers that are located within the Mississippi River Floodplain, and those sanitary sewers located near water bodies. The assumption is that those sanitary sewers may be more likely to be located near or below the seasonal water table. Therefore, reviewing, and potentially addressing, the observed instances of I/I in these sewers may resolve much of the Riverdale contribution of the excessive flow to the Davenport wastewater treatment plant during times of rainfall and high water in the Mississippi River. The recommended sewers to be evaluated included those in the Havens Acres area, those along South Bellingham Street, those along Fenno Drive and Fenno Road, those along Valley Drive, and finally, those along the tributary to Crow Creek located in the Scott Community College woods. The sanitary sewers located in Havens Acres, along South Bellingham Street, along Fenno Drive, and Fenno Road, solely provide sanitary sewer service to the City of Riverdale. The sanitary sewer located along the tributary to Crow Creek, while owned by the City of Riverdale, provides sanitary sewer service to Scott Community College, Pleasant Valley High School and a portion of the City of Bettendorf. Please note that the following sanitary sewer pipe runs were not evaluated as part of this project: • The sanitary sewer that is located on the west side of the future Woods Estates and provides conveyance to most of the Manor Drive, Circle Drive, and Fieldcrest Road Area. This same sewer will provide service to most of the future Woods Estates. • Manor Drive, Circle Drive, and Fieldcrest Road Page 1 © February 2019 MSA Professional Services, Inc.. P:110800s110870s1108761108760561Reports Sanitary Sewer Evaluation City of Riverdale, Iowa • Elmhurst Lane, Windsor Road, and the sanitary sewer located along the driveway for the current Mayor. Please note that on some maps this drive is also identified as Windsor Lane. • Belmont Road (Not the Scott Community College Belmont Road) • The sewer to Pleasant Valley High School and Bettendorf areas located north of Riverdale. • Sanitary sewers that are internal to Arconic, Scott Community College, Pleasant Valley High School, and those industry areas located to the east of Arconic. • Finally, the televising of the sanitary sewer that runs through the Scott Community College woods was not completed. B. Purpose and Scope On January 5, 1974 the cities of Davenport, IA, Bettendorf, IA, Riverdale, IA, and Panorama Park, IA entered into an intergovernmental agreement providing for joint use of sanitary sewers and sewage disposal facilities. The Davenport, IA wastewater plant has historically received sewage flow rates and volumes far exceeding the plant's design capacity. In an Administrative Consent Order entered into with the Iowa Department of Natural Resources (Appendix A), the Joint Use Cities agreed to undertake the wastewater collection, handling, and treatment projects set forth in the Joint Sewer Use Communities Capital Improvement Plan (CIP) submitted to the DNR on March 30, 2012. One of the deadlines outlined within this document is that the Joint Use Cities shall undertake the study and actions to remove I/I sources from interceptor sewers. Therefore, the primary objective of this study and subsequent proposed remedial action is to eliminate (or reduce) instances of I/I. A secondary objective has been to note other deficiencies or problems so that they can be addressed in the future. Riverdale is proceeding with this sanitary sewer evaluation effort to identify sources of I/I and deficiencies within their sanitary sewer collection and conveyance system. This is accomplished by performing sanitary sewer smoke testing and televising of the sanitary sewers of concern. As a result of these investigations, noted I/I sources, as well as other sewer deficiencies, were located and evaluated for correction. The purpose of this report is to evaluate the City's sanitary sewer collection system, and identify any deficiencies that contribute to I/I. Information presented in this evaluation is based on field investigation performed by MSA Professional Services and televising performed by the City of Bettendorf, IA, Public Works Department. Page 2 © February 2019 MSA Professional Services, Inc.. P:110800s110870s1108761108760561Reports Sanitary Sewer Evaluation City of Riverdale, Iowa The scope of this report is to: • Provide a brief summary of efforts to complete the Sanitary Sewer Collection System Evaluation. • Review televising video footage from the sewer televising videos. • Prepare a list of the observed sources of I/I, as well as other sanitary sewer deficiencies, and prioritize this list. • Provide opinions of probable construction cost to Riverdale to mitigate these deficiencies related to I/I.. C. Pipe Material Properties and Historical Performance The sanitary sewer material utilized to construct most of the sanitary sewer in the areas of this study is vitrified clay pipe. The observed pipe segments tend to be very short. Thus, there are many pipe to pipe joints. Vitrified clay pipe is an excellent material for sanitary sewage. For the most part it is inert and will not react with chemicals and waste conveyed by the pipe. In addition, it is not affected by corrosive or polluted soils. Vitrified clay pipe is a strong material and can be readily molded to many shapes. The interior of the pipe itself is low in friction. The pipe is susceptible to impact forces. The pipe will readily crack when subjected to impact and tensile forces. It has very poor resiliency characteristics. If deformed, it will break and generally not return to shape. When dropped or struck, there is a good potential the pipe material will crack. Long segments of vitrified clay pipe are generally not feasible because the installation of the pipe will introduce tensile forces during picking up and placing the pipe. Subsequently, the pipe could crack due to uneven support of the pipe during placement. Finally, the pipe is a relatively heavy material. For an 8 -inch diameter pipe section, the pipe will weigh about 17 pounds per foot. This compares to 5 or 6 pounds per foot for PVC pipe material. It took a long time for the development of an effective pipe joint for vitrified clay pipe to be developed. This is because sanitary sewers initially discharged directly to a water body without treatment. Thus, inflow at the joints was encouraged to assist in keeping the pipe clean. Just prior to World War II, the development of a good pipe to pipe joint became a concern. The first joint material was oakum. Oakum is a fiber material, usually made from hemp, which is coated with bitumen material. Installation is done by packing the oakum into pipe joints. Unfortunately, while an excellent craftsman could make an excellent joint, many sanitary sewers were not constructed by a craftsman. Furthermore, oakum joints did not allow for pipe movement. Thus the concern to find a better joining system. The next step in the evolution of pipe joints was poured mastic joints. Poured joints are effective at Page 3 © February 2019 MSA Professional Services, Inc.. P:110800s110870s1108761108760561Reports Sanitary Sewer Evaluation City of Riverdale, Iowa initially preventing inflow. However, with age, and pipe movement during backfilling and settling, the joint will likely fail. The next evolution of joints was a tubular joint seal. This was made by a hollow rubber tube that is pumped with grout under pressure to seal the pipe to pipe joint. Based on readily visible evidence, this appears to be the type of joint that is utilized in most of the observed videos of the Riverdale sanitary sewers. It was not until the establishment of an ASTM test (C425) in 1958 that an elastomeric gasket for clay pipe was developed. A failed pipe joint allows for the inflow of ground water, the intrusion of plant roots, the slow but inevitable loss of soil surrounding the pipe, poor flow characteristics at the pipe section transition, and the creation of catching points for debris that is flowing within the sewage. Some of the other pipe material noted in the Riverdale sanitary sewers that were evaluated included concrete pipe and ductile iron pipe. Both concrete pipe and ductile iron pipe are strong pipe, have good interior flow properties, can be constructed in relatively long sections, have some resiliency due to loading, have good to excellent impact resistance, and, in general, are excellent pipe materials. However, both concrete and ductile iron pipe are relatively heavy compared to PVC pipe. Eight (8) inch diameter ductile iron pipe will likely weigh about 22 pounds per foot. Eight (8) inch diameter concrete pipe will likely weigh about 27 pounds per foot. These days both pipes are easily installed utilizing modern day construction equipment. Both materials are very susceptible to the corrosion caused by sanitary sewage. The formation of hydrogen sulfide gas in a sanitary sewer environment, will lead to the development of a weak sulfuric acid that forms with the condensation in pipes. This sulfuric acid will rapidly corrode the concrete and ductile iron pipe. Generally, special coatings are required to prevent or halt the corrosion of sanitary sewers constructed of these materials. Page 4 © February 2019 MSA Professional Services, Inc.. P:110800s110870s1108761108760561Reports Sanitary Sewer Evaluation City of Riverdale, Iowa II. SANITARY SEWER TESTING AND INSPECTION An investigation of the three (3) areas of the sanitary sewer collection system, determined by the City with the assistance of MSA Professional Services was performed. The location of these areas are shown on Figure 2 — Areas of Study and Manhole Key Map. A. Smoke Testing Smoke testing was systematically performed on November 2nd, 3rd, 16th, and December 28th, 2018 within the collection system to identify sources of surface inflow such as storm sewer cross connections, illegal connections of roof and foundation drains, sump pumps, yard and area drains, displaced manhole castings, and manholes located in areas of ponding water that do not have properly sealed lids and frames. A map of manholes that were smoke tested is shown on Figure 3 — Manholes Blown with Smoke. Smoke testing consists of placing a centrifugal blower on top of a manhole, thus forcing smoke through the sanitary sewer pipes. Observations of smoke emissions in the test areas were recorded with hand written field notes and digital photographs. This methodology provides comprehensive coverage of the sanitary sewer system piping in each area. There were a few sources of surface inflow located during the smoke testing. The major sources identified are open (uncapped/broken) cleanouts on laterals. A significant number of manholes in the collection system have poorly sealed castings and are equipped with open -pick hole lids. Thus, smoke was also observed discharging from these structures. Open pick holes on sanitary sewers that are not located in areas of ponding water are probably not a significant concern. However, open pick -hole covers on sanitary manholes in areas of flooding or ponding water are a ready source for the entry of surface water into the sanitary sewer system. In these situations, the frame and grate should be replaced with a sealing lid and frame, eliminating the pick hole. Table II -1, Smoke Test Summary, indicates the number of occurrences of each type of deficiency found in the sanitary sewer collection system during the smoke testing analysis. A detailed list of all findings from each smoke test setup as well as photographs from smoke testing are located in Appendix B. Note that no instances of possible surface water inflow were identified by the smoke testing of the sanitary sewer located along the tributary to Crow Creek that is located within the Scott Community College woods.

Sanitary Sewer Televising Televising was conducted by the City of Bettendorf, IA, Public Works Department on multiple days from December 11th, 2018 to December 28th, 2018. The areas televised are referred to as Areas 1 & 2 on Figure 2. Area 3 was not televised as the off -road conditions did not allow for the utilization of Bettendorf s equipment. The manholes and pipe runs that were televised are shown on Figure 4 — Televised Sanitary Sewer. The review of the televising video revealed multiple defects in the sanitary sewers within Areas 1 & 2. The deficiencies include instances of faulting at joints, fractures and cracks, and broken pipe joint gaskets. If joints are not properly sealed or if cracks exist, these deficiencies in the pipe become subject to intrusion by roots and ground water inflow. If untreated, the intrusion of roots will grow to root masses. Root masses will eventually reduce or block flow of sewage through the pipe. Many of the sanitary sewer pipe runs between manholes were noted to not be at a consistent grade. Where settling occurred such that the grade of the pipe to the downstream manhole became positive, sewage will pond within the pipe. These sags in the pipe runs are often referred to as "a pipe that has a belly". The presence of a belly in a pipe allows debris, grit, and sediment to settle out of the flow. This reduces the flow capacity of the pipe. Thus, hindering the pipe's ability to convey sewage. Generally, unless the sewer is dug up and re- constructed with a consistent negative slope, it is not possible to solve the problems created by bellies. Consistent and regular pipe cleaning is called for. All lateral connections that are not labeled as capped (in Appendix B) are "active" and constant flow was observed in the videos. Through dye testing, it is possible to correlate appropriate sanitary laterals that convey sewage from a house, to laterals that may be illegally or inappropriately sealed. Dye testing is beyond the scope of this study. However, anecdotally, MSA believes the instances of illegal or inappropriate connections is minor compared to the number of bad pipe joints that were observed. These bad joints allow, or may allow during times of a higher ground water table, inflow into the sanitary sewer. Table II -2 — Televising Summary indicates the number of occurrences of each type of deficiency found in the sanitary sewer collection system during televising, as well as recommended corrective action. A detailed table of all television findings, including the location of each deficiency is located in Appendix C. Page 9 © February 2019 MSA Professional Services, Inc..

A total of 38 pipe runs were evaluated by televising. In order to effectively evaluate the condition and priority of each pipe run as related to I/I, a ranking system was developed. This ranking system evaluates each pipe run on a scale of 1-5. Table II -3 — Sewer Evaluation Key, is the method that was utilized to evaluate each pipe run. A summary of this evaluation is shown on Table II -4 — Televising Evaluation Summary. Page 10 © February 2019 MSA Professional Services, Inc..

Recommendations After identifying sewer main and manhole deficiencies the following possible remedial actions are presented as actions to improve the state of the sanitary sewer system, prolong the life of the sanitary sewer, and, most importantly, decrease the amount of I/I into the sanitary sewer system. 1. Rehabilitation by CIPP (Cured in Place Pipe) Lining In cases of occurring infiltration at pipe joints, lining the existing sanitary sewer pipe will eliminate infiltration and prolong the life of that run of sanitary sewer. There are sources of have observed infiltration occurring. Of these instances of observed infiltration, four (4) will benefit immediately from the construction of a cured in place pipe lining. This lining totals about 1,823 LF of 8 -inch sanitary sewer pipe. Along with the lining of the sanitary sewer pipe, all sanitary laterals located on lined pipe runs will need to be reinstated, connection grout sealed, and tested. The sanitary sewer runs that are recommended to have a constructed cured in place pipe lining are located on Wisteria Lane, South Kensington Street, South Bellingham Street, Fenno Drive, Valley Drive, and Sycamore Lane. 2. Rehabilitation of Manhole Interior (Cementitious) In three (3) cases manholes have been observed as a major source of infiltration. These three manholes are located on South Bellingham Street. Through our smoke testing investigation several other sources of surface water inflow were observed on the southerly pipe runs. These sources are the abandoned sanitary laterals that provided sanitary sewer service for former houses that were located on the west side of South Bellingham Road. These former sanitary laterals should be plugged. As an alternative to plugging the manholes, it may be possible to abandon in place, some of the southerly pipe runs. However, the manholes of concern are located downstream from these sources of surface water inflow. 3. Sanitary Sewer Pipe Point Repair, 8" In pipe runs where cracked pipe, faulting of pipe sections, or the failure of pipe joint gaskets was observed, it is possible to construct a single repair at that point for significantly less cost than constructing a cured in place pipe lining. However, unless the source of infiltration is a single crack or a lateral joint(s), because of the type of pipe joint gasket that appears to be utilized and because of the number of joints that occur in a sanitary sewer constructed of vitrified clay pipe, there is a long-term benefit derived from constructing a cured in place pipe lining. MSA will evaluate sewers that are a high priority to address on a case by case basis. Page 13 © February 2019 MSA Professional Services, Inc.. P:110800s110870s1108761108760561Reports Sanitary Sewer Evaluation City of Riverdale, Iowa 4. Replace Manhole Casting and Sealed Lid During smoke testing and televising it was observed that 12 sanitary sewer manholes are in need of new castings and sealed lids. It is recommended that these manhole castings and lids be replaced based on the associated sanitary sewer priority ratings. 5. Removal of Root Ball from Sanitary Sewer In reviewing the videos, MSA noted a significant root intrusion that will most likely cause a severe flow blockage if not addressed in the very near future. Roots that are removed will grow back stronger. Either the area on the outside of the pipe have to be treated to kill the root, the joint should have a constructed grout seal, or the pipe should be lined. Grout sealing or killing the root could be effective measures at preventing the root from growing back, but they are not a guarantee. External excavation of the pipe can provide a guarantee that the root will not return. However, that is extremely disruptive. Constructing a cured in place pipe lining provides the least disruption and best assurance that the root will not grow back. 6. Plugging Sanitary Sewer Laterals or Removing Clean Outs Several cleanouts were observed during the smoke testing that were in extremely poor condition. It is very likely that surface water inflows are entering the sanitary sewer system at these locations. If the lateral is part of a functioning conveyance of wastewater to the sanitary sewer, the cleanout should be reconstructed. If the sanitary lateral has been abandoned, then the cleanout should be removed and the lateral plugged. B. Opinions of Probable Cost MSA prepared opinions of probably construction cost to address those pipe runs and manholes that are rated 4 or 5 in the Havens Acres Area, and rated 5 at other locations. The intent of recommended remedial actions, for which MSA has prepared their opinion of the probable construction cost, are to remove I/I per the Administrative Consent Order. Though many other pipe defects were observed that did not contribute to I/I, MSA recommends to forgo the construction of remedial measures where infiltration or surface water inflow was not observed. The reason that an opinion of the probable construction cost was prepared for pipe runs with a rating of 4 in the Havens Acres area is because of the high probability these roadways will be reconstructed in the near future. Page 14 © February 2019 MSA Professional Services, Inc.. P:110800s110870s1108761108760561Reports Sanitary Sewer Evaluation City of Riverdale, Iowa A summary of probable construction cost by region of the City is as follows: • Havens Acres — $73,500 • East Riverdale — $22,800 • Arconic Area — $22,800 These probable construction costs include MSA's best estimate of design fees to prepare projects for bidding, MSA's best estimate to administrate the projects during the construction phase, a contingency factor, and an attempt to account for inflation (4%) for a period of one year. The opinion for the probable cost to address the three areas of the City which were the focus of this study is $116,100. The breakdown and cost summary of the noted remedial measures to remove I/I is included in Appendix E. Page 15 © February 2019 MSA Professional Services, Inc..

An intergovernmental agreement providing for construction and joint use of sanitary sewers and sewage disposal facilities was signed by the City of Davenport, Iowa, the City of Bettendorf, Iowa, the City of Riverdale, Iowa and the City of Panorama Park, Iowa on January 5, 1974. This agreement which has been amended continues to be the basis for operating, maintaining, and financing the common plant and system assets. 2. The Joint Use Cities own and operate the Joint Sewerage Committee Water Pollution Control Plant, a mechanical wastewater plant serving approximately 29,590 residential connections, 7,032 commercial connections, and 20 industrial connections in the city of Davenport. The plant also serves approximately 12,749 residential connections, 776 commercial connections and 3 industrial connections in Bettendorf. Approximately 200 residential connections and 10 commercial connections are served in Riverdale. The plant serves approximately 55 residential connections in Panorama Park. The wastewater plant is designed to handle an average dry weather flow of 26.0 million gallons per day (mgd) and an average wet weather flow of 40.0 mgd. A construction permit was issued by the DNR on March 15, 1974 for the construction of the Davenport Water Pollution Control Plant in accordance with current NPDES. 3. The Davenport wastewater plant has historically received wet weather flows in volumes far exceeding the plant's design capacity. These excessive flows result in the discharge of untreated wastewater from the collection system and partially treated wastewater from the plant, blended with treated wastewater. 4. Pursuant to 567 IAC 60.2, a bypass is the diversion of waste streams from any portion of a treatment facility or collection system. A bypass does not include internal operational waste stream diversions that are part of the design of the treatment facility, maintenance diversions where redundancy is provided, diversions of wastewater from one point in a collection system to another point in a collection system, or wastewater backups into buildings that are caused in the building lateral or private sewer line. 2 IOWA DEPARTMENT OF NATURAL RESOURCES ADMINISTRATIVE CONSENT ORDER JOINT USE CITIES 5. In 2010, the Joint Use Cities discharged 547.7 million gallons of partially treated wastewater to the Mississippi River at the wastewater treatment plant over a total of 74 separate days of discharge. In addition to these discharges, Davenport reported the discharge of untreated wastewater from the wastewater collection system on three occasions in 2010. 6. In 2009, the Joint Use Cities discharged 723.8 million gallons of partially treated wastewater to the Mississippi River at the wastewater treatment plant over a total of 90 separate days of discharge. In addition to these discharges, Davenport reported the discharge of untreated wastewater from the wastewater collection system on 18 occasions in 2009. 7. The Davenport Water Pollution Control Plant also serves Bettendorf, Riverdale and Panorama Park. Each city owns and maintains the wastewater collection system within each respective city limits and proportionately shares in the ownership, cost of operation and maintenance of the Davenport Water Pollution Control Plant. Proportionate ownership is allocated based on a community's use expressed as a percentage. Percentages for fiscal year 2012 are: Davenport, 79.66%; Bettendorf, 19.81'%; Riverdale, 0.46%; and Panorama Park, 0.07%. 8. When influent flow to the wastewater plant exceeds the plant's design capacity, influent flow is restricted and backs up in the Bettendorf collection system. In 2010, the City of Bettendorf reported discharging over 33.2 million gallons of untreated wastewater to the Mississippi River over the course of 7 separate incidents lasting 11 days. 9. The Department and the Joint Use Cities have been working together for several years to develop a strategy to eliminate or minimize the bypassing of partially treated wastewater at the Davenport Water Pollution Control Plant and within the wastewater collection systems of the Joint Use Cities. 10. The Joint Use Cities have committed to a 20 -year Capital Improvement Plan that contains at least 20 sewer -related projects at a cost of over $160 million dollars. 11. This Order is intended to establish a schedule for the completion of wastewater collection, handling and treatment improvements necessary for the Joint Use Cities to achieve compliance with applicable regulations. In the event a signatory fails to abide by the schedules contained herein, each or any of the other signatories may enforce this Order against the breaching party. IV. CONCLUSIONS OF LAW The DNR and the Joint Use Cities agree that the following conclusions of law are applicable in this case: 1. Pursuant to Iowa Code section 455B.186(1), a pollutant shall not be disposed of by dumping, depositing, or discharging such pollutant into any water of the state, except that 3 IOWA DEPARTMENT OF NATURAL RESOURCES ADMINISTRATIVE CONSENT ORDER JOINT USE CITIES this section shall not be construed to prohibit the discharge of adequately treated sewage, industrial waste, or other waste pursuant to a permit issued by the director. 2. Pursuant to 567 IAC 63.6, bypasses from any portion of a treatment facility or from a sanitary sewer collection system designed to carry only sewage are prohibited. Pursuant to 567 IAC 60.2, a bypass is the diversion of waste streams from any portion of a treatment facility or collection system. A bypass does not include internal operational waste stream diversions that are part of the design of the treatment facility, maintenance diversions where redundancy is provided, diversions of wastewater from one point in a collection system to another point in a collection system, or wastewater backups into buildings that are caused in the building lateral or private sewer line. The DNR has documented violations related to untreated discharges by the Joint Use Cities, as documented in the Statement of Facts above. 3. Pursuant to 567 IAC 64.2(10)"b", a sanitary sewer construction permit may be denied if bypassing has occurred at the treatment facility, except when any of the following conditions are being met: (1) The bypassing is due to a combined sewer system, and the facility is in compliance with a long-term CSO control plan approved by the department. (2) The bypassing occurs as a result of a storm with an intensity or duration greater than that of a storm with a return period of five years. (3) The department determines that timely actions are being taken to eliminate bypassing. 4. Pursuant to 567 IAC 64.2(10) "c", a sanitary sewer construction permit may be denied if an existing downstream sewer is or will be overloaded or surcharged, resulting in bypassing, flooded basements, or overflowing manholes, unless: (1) The bypassing or flooding is the result of a precipitation event with an intensity or duration greater than that of a storm with a return period of two years. (2) The system is under full-scale facility planning (I/I and SSES) and the applicant provides a schedule that is approved by the department for rehabilitating the system to the extent necessary to handle the additional loadings. V.
