I. Introduction A National Pollutant Discharge Elimination System (NPDES) Permit (NE0133680) for City of Omaha Combined Sewer Overflows (CSO) was issued by the Nebraska Department of Environmental Quality (NDEQ) and became effective on October 1, 2010 and expires after a five-year period on September 30, 2015. This permit requires the City of Omaha to submit an Annual Report to the NDEQ within 30 days following October 1, 2011 and within 90 days following each yearly (Oct 1–Sept. 30) anniversary. This is the first Annual Report under this permit for the period of October 1, 2010 through September 30, 2011. Throughout the report, the permit will be called out as the CSO NPDES Permit.
The CSO NPDES Permit states that, “this permit specifically authorizes wet weather discharges from the City of Omaha’s combined sewer system (CSS) through CSO outfalls according to the requirements, conditions, and limitations set forth in the permit. CSO outfalls are defined as designated overflow points in the combined sewer system (CSS) designed for the purpose of allowing the discharge of wet weather flows to receiving waters prior to receiving complete treatment in the City’s Wastewater Treatment Plants.”
There are 18 CSO outfalls associated with the Missouri River Wastewater Treatment Plant (MRWWTP) collection system and 11 CSO Outfalls associated with the Papillion Creek Wastewater Treatment Plant (PCWWTP) collection system. Only one of the 29 CSOs undergoes treatment prior to discharge of the combined sewer flows. The MRWWTP manages CSO Outfall 102 which, under approved conditions, discharges combined wastewater that has received primary treatment but not secondary treatment.
Information is provided in this Annual Report, as required by the CSO NPDES Permit, on actions, activities, and measures taken by the City of Omaha with regard to Nine Minimum Controls (NMC), Long Term Control Plan (LTCP), compliance schedule, CSO discharge monitoring and in-stream monitoring. The last section is reserved for other information and includes narrative on reduction of overflows and/or CSO outfalls as well as any other information that benefits measuring the success of achieving improved water quality. Annual progress reports for LTCP Projects are provided as an attachment. They include general descriptions of the work that took place on each project over the reporting period, if it conformed to the LTCP and schedule, and any planned or expected deviations from the LTCP. Documentation to track justification for any such potential deviations from schedule or LTCP is also provided as an attachment to this Annual Report.
The Environmental Services of the City Of Omaha Public Works Department oversees the administration of the CSO NPDES Permit and ensures that the City is in compliance with the permit requirements. The information provided in this report is a result of the cooperation among the Sewer Maintenance Division, Quality Control Division, PCWWTP and MRWWTP, and CSO Program Management. II. Executive Summary This section provides a brief summary of this Annual Report, and highlights primary points and statements on the City of Omaha’s effort to comply with the CSO NPDES Permit. It is important to note up front in this document that the City of Omaha experienced severe flooding - 3 - ______
of the Missouri River during this Annual Report period, which will be touched on throughout the report with the primary factors elaborated in the last section of the report. This executive summary is written in the order of the main report sections.
A. Nine Minimum Controls (NMC) As stated in the CSO NPDES Permit, “Nine Minimum Controls (NMC) are operations and procedures that will reduce combined sewer overflows and their effects in receiving water quality that do not require significant engineering studies or major construction and are consistent with the complete LTCP.” The City continues to implement the NMC and documents existing efforts, new evaluations and review of procedures, keeping in mind the goal of reducing CSOs and improving water quality if possible. The Annual Report covers these nine controls: 1) proper operation and maintenance; 2) maximizing the use of the collection system; 3) review and modification of pretreatment programs; 4) maximization of flow to the POTWs for treatment; 5) prohibition of CSOs during dry weather; 6) control of solid and floatable materials; 7) pollution prevention; 8) public notification; and 9) monitoring to characterize CSO impacts and the efficacy of CSO controls.
B. LTCP Documentation The CSO NPDES Permit requires documentation and reports to showing compliance with the conditions and requirements with regard of the main elements in the LTCP. One of the elements reported on in this Annual Report is on characterization and modeling of the CSO system which includes a brief discussion of the further characterization, monitoring, and modeling efforts completed over the report period. The subsequent elements in this annual report are updates, as required, on the public participation plan, consideration of sensitive areas, evaluation of alternative, cost and performance considerations, operational plan, maximizing treatment at the existing POTW treatment facilities, implementation schedule, and post-construction compliance monitoring.
C. Compliance Schedule As required by both the CSO NPDES Permit and the Consent Order (August 8, 2007, NDEQ Case No. 2710), the status of the implementation of the LTCP is provided. Individual or “component projects” progress reports are also included to provide descriptions and potential changes from the LTCP.
The pie chart shown to the right is graphic Total Projects (OPW Numbers) = representation of the projects status and Projects 105 Projects illustrates that ten projects have tasks such as Behind with final design that are behind schedule but are on Schedul Tasks track to finish construction on schedule. One e BehindProjects project might finish construction late, as 1 Sched…on Schedul described in the report. Also noted is that 87 Projects e original LTCP projects are currently being Not In- Complet 20 implemented through 105 contracts having Progress ed Omaha Public Works (OPW) numbers. Out of 69 Projects that number, 36 are completed or underway. Note: There were 87 LTCP Projects.5 Delays in a project do not necessarily result in the delay of the overall implementation of the - 4 - ______
LTCP. The City has documented any project delays, justifications for those delays, and mitigations taken to bring back onto schedule, which are included in an attachment to this Annual Report.
D. CSO Outfall Monitoring The CSO NPDES Permit in Part II and Part III requires the monitoring of the MRWWTP outfall 102 and other selected CSO outfalls (105, 106, 107, 108, 202, and 205) for certain water quality parameter. Due to the Missouri River Flood, samples were not able to be obtained at outfalls 105, 106, 107, and 108. Obtaining samples at CSO 102 was also affected by the flooding this year; however, some data was obtained and is presented in the report.
E. In-stream Monitoring The in-stream monitoring is managed by the City of Omaha Quality Control Division to provide for the requirements of the CSO NPDES Permit but also to meet the requirements of the City’s MS4 Permit. The annual report for the MS4 Permit will be submitted for the period January 1 to December 31, 2011. At this time data has not been gathered for a long enough period of time to establish any trends in the effects of the CSO or MS4 program on the water quality of the receiving streams.
F. Other Information The CSO NPDES Permit, Part VII.F suggests that the City should include in the annual report, other information that may address “measures of success” for the Program such as reduction in the number of overflow events, reduction in the number of CSO outfalls, or other indicators or improvements of receiving water quality. This year’s report also includes information on the Missouri River Flood of 2011 and its effects on the CSS, as well as the City of Omaha’s ongoing RNC program, and a discussion on rates and the City’s ability to pay for the program. At the request of the NDEQ Waste Management Division, a paragraph will be included in the report each year that discusses contaminated soils that are encountered during the construction of capital projects associated with the CSO Program.
The Missouri River Flood of 2011
In 2011 record amounts of snowpack and rainfall in the upper Missouri River Basin resulted in runoff that exceeded the capacity of the five reservoirs that are managed by the U.S. Army Corps of Engineers (USACE). With no available capacity to store the inflows into the system, the USACE had to release the water downstream, resulting in excessive and prolonged flooding in the Omaha area. The flooding greatly impacted the city’s ability to maintain the portions of the CSS and at times impacted the city’s ability to deliver flow from the CSS to the treatment plants. The City communicated with the NDEQ early on a frequent basis and later as situations arose to provide information on the impacts to the CSS and the WWTPs. The flooding resulted in a prolonged upset condition to the City of Omaha’s treatment and collection system, with conditions varying throughout the flood due to many factors, including rainfall, river levels, and elevated groundwater tables.
- 5 - ______
III. Nine Minimum Controls As stated in the CSO NPDES Permit, “Nine Minimum Controls (NMC) are operations and procedures that will reduce combined sewer overflows and their effects in receiving water quality that do not require significant engineering studies or major construction and are consistent with the complete LTCP.” As required by the Environmental Protection Agency CSO Control Policy (April 19, 1994, at 59 Fed. Reg. 18688), “to demonstrate the implementation of the nine minimum controls”, the City of Omaha submitted the appropriate documentation in and prior to 2006. Summaries of the NMC objectives and required submittals can be found on record in the City of Omaha 2007 Combined Sewer Overflow Permit Annual Report NPDES Permit No. NE0133680. The City continues efforts to follow procedures and documentation to assure the NMC are being met.
The documentation included in this section has been written according to the conditions and requirements of Part IV of the CSO NPDES Permit.
A. Proper Operation and Maintenance (O & M)
The requirements of the CSO NPDES Permit further define proper operation and maintenance of the CSS and CSO outfalls to include periodic reviews of O&M procedures, updates as needed, and that the procedures are documented with a major emphasis on the elimination of dry weather overflows. City of Omaha O & M procedures, with regard to the CSS and CSO, are reviewed on a semi-annual basis. If a revision is deemed necessary, the documentation of the revisions may occur more or less frequent depending on the criticality of the procedural change.
No significant revisions to the O & M procedures were documented in this report period. However, procedures were adapted ad hoc to address the emergency needs with regard to the effects of the Missouri River Flood. MRWWTP and PCWWTP adapted wet-weather procedures when the plants were not able to utilize CSO 102 and CSO 201. Additionally, several CSO stations were not able to operate normally and temporary pumping stations were set up to pump combined sewer overflows over the levee at CSO 106/107 - North Interceptor /Grace, CSO 108-Burt Izard, 121-Jones St, CSO 110-Pierce, CSO 111-Hickory, CSO 115-Riverview, and CSO 117-Missouri Ave. More information on the Missouri River Flood can be found in Section VIII of this report.
The City’s will continue to adhere to this NMC to properly operate and maintain the CSS and the CSO outfalls by utilizing current procedures and implementing new procedures as necessary.
B. Maximize Use of the Collection System for Storage The CSO NPDES Permit requires the City to continue to implement their program to maximize the use of the collection system for storage as well as review the CSS, as appropriate, to identify any locations where minor modifications can be made to increase in-system storage. The permit requires that any modifications shall be implemented as soon as practicably possible and documented in this Annual Report.
- 6 - ______
Previous studies have shown that the City of Omaha’s CSS has a negligible amount of storage available, and that attempting to use the existing system for storage to reduce CSOs may result in an increase of property damage upstream due to basement backups and street flooding. The computer model for the CSO LTCP was last updated in 2009. As part of this effort, an evaluation of potential capacity within the sewer system was made. The evaluation resulted in preliminary maps showing locations where further analysis was needed for consideration of in- system storage in the future. Such information must be considered carefully, as a large part of the LTCP involves sewer separation that will open up capacity within the system, and in many cases that capacity will be needed to prevent bottlenecks and other problems. Additional flow monitoring was performed in 2010 and will be used to refine the model; however the objective of the flow monitoring was not to evaluate the system further for storage. Consistent with the adaptive management strategy for the entire LTCP, the potential for in-system storage will continue to be evaluated as new information is learned and new technologies become available.
A project that was developed as a part of the City RNC program, 20th and Poppleton, is noteworthy under this NMC. The project is within the Leavenworth CSO 109 basin. The project was not included in the CSO Program as its original intended concept was to reduce basement backups with the construction of a local parallel sewer to be reconnected into the combined system, thus providing no overall benefit to water quality at the receiving stream. The concept for the project evolved into the use of an open bottom underground detention tank that would hold the separated storm flows until the peak flows in the combined system pass. The project will result in a reduction of peak flows at CSO 109. It has not been analyzed yet as to how much of the peak flow reduction will result in the ability to send more flows to treatment; however, the peak flow reduction and spreading of the CSO volume over time may allow for a greater amount of treatment of flows to be achieved. A small reduction in the overall volume will be achieved with the open bottom to the detention basin, as this is designed to allow infiltration into the soil. The project is currently under construction, with an estimated cost of $5.5 million.
C. Review and Modification of Pretreatment Programs The NPDES Permit requires the City to minimize the impacts of discharges into the CSS from non-domestic sources. When new significant industrial users are added to the CSS, the City is required to determine what impact the dischargers would have on the quality and quantity of CSO discharges during wet weather events. A summary of new significant industrial users and measures taken the City to address any discharges during wet weather are documented in this Annual Report.
The City of Omaha Quality Control Division is responsible for the review and modification of the Pretreatment Program. The facilities with Nebraska Pretreatment Program permitted discharges, either through voluntary agreements or through the NPP permit, are requested, whenever possible, to restrict or prohibit discharges during rain events. During this report period there were no additional industrial users added within the CSS. However, two additional dischargers within the sanitary sewer system (contributing to the PCWWTP) were permitted by the NDEQ effective October 1, 2010. Wet weather discharges for these industries, JN-International Medical Corporation and Lindsay Corporation, and six other sanitary sewer dischargers are regulated under their NPP permits.
- 7 - ______
A total of 11 NPP permitted facilities are located in the CSS area and were operating during this permit year. These facilities are listed in Table 1. Omaha Antique & Job Plating Co. Inc. located at 846 South 24th Street, has been removed from the list due to the business ceasing operations and final inspection was completed by the NDEQ on January 8, 2011. Syngenta Crop Protection Inc., NPP permit issued October of 2006, was inadvertently left off of past CSO Annual Reports due to unique NPP permit requirements; however, the industry does have wet-weather discharge restrictions and has been added to Table 1.

Syngenta Crop Protection, Inc. 4111 Gibson Road 115 Yes * Roberts Dairy and Armour Eckrich Meats LLC are included as NPP industries in the CSS however these industries are not batch dischargers and therefore the City does not regulate their discharges during wet weather.
D. Maximization of Flow to the POTWs for Treatment Maximization of flow to the POTWs involves simple modifications to the CSS and treatment plant to enable as much wet weather flow as possible to reach the treatment plant. The CSO NPDES Permit requires, as appropriate, the City of Omaha to evaluate and implement simple modifications to the CSS and procedures at the treatment plants to maximize flow to the POTWs. Any modifications are documented in this Annual Report.
During the permit year no permanent changes to existing policies were made to maximize flow to the treatment facilities. However, as stated previously in Section A for Proper Operation and Maintenance, procedures were adapted ad hoc to address the emergency needs with regard to the effects of the Missouri River Flood.
- 8 - ______
E. Prohibition of CSOs during Dry Weather
As stated in the CSO NPDES Permit, “Dry weather overflows from the City of Omaha combined sewer system are prohibited.” The CSO NPDES Permit requires the City of Omaha to document all dry weather overflows and the measures taken to correct the cause of the overflow in this Annual Report.
The City of Omaha continues to work to comply with meeting the control of prohibition of dry weather overflows. The City exercises careful procedures for documentation and reporting of dry weather overflows in an effort to prevent future overflows other than those that result from conditions that constitute an upset. As defined by NDEQ Title 119 -"Upset" means “an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed or inadequate treatment facilities, or careless or improper operation and maintenance.”
With the Missouri River Flood, reporting procedures were followed to the extent possible. Many of the City personnel responsible for reporting dry weather overflows to NDEQ were heavily involved with protecting the City and managing emergency responses. The NDEQ was contacted by phone and email throughout the duration of the flood fighting efforts. More information on the flood can be found in Section VIII of this report.
Table 2 summarizes dry weather overflows from the CSS that reached waters of the State from October 1, 2010 to September 30, 2011. Five of the recorded overflows below are attributed to the effects of the Missouri River flooding and can be distinguished by the entry of “Other” for the mitigation steps. The corrective action taken at the Monroe Street Lift Station was that the lift station was restored at a time after the flood event was considered over. The pump stations along the Missouri River sustained severe damage. The long term corrective action is that the City is working on contracting engineering and construction services to get the pump stations repaired or replaced where necessary.
Additional information on all of the events listed in the Table 2 was submitted to NDEQ, in accordance with reporting requirements in the CSO NPDES Permit. No formal written follow up report was submitted for the overflow at the Monroe Street Lift Station. There was a press release issued shortly before the diversion gate was closed and the NDEQ has been informed otherwise of the details of this overflow. The related press releases are in Attachment 2 – Dry Weather Overflow Media Releases.
The City of Omaha also tracks dry weather excursions in the CSS that re-enter the combined system and the seventeen (17) events are listed in Table 3. Most of the excursions were confined to private property as basement back-ups or escaped the system through a manhole but remained within the storm drainage area of the combined sewer and either directly entered a storm inlet or settled in the area. One instance, cited as caused by “Sewer Overload”, occurred as a result of the Missouri River intrusion into the combined sewer system. Additional details on each of the events were reported to NDEQ at the time of occurrence in accordance with reporting requirements in the CSO NPDES Permit.

F. Control of Solid and Floatable Materials in CSOs As stated in the CSO NPDES Permit, “control of solid and floatable materials in CSOs is intended to reduce visible floatables and solids using relatively simple measures.” The permit requires the City to, as appropriate, reassess and implement site-specific processes to control solids and floatables in CSOs using relatively simple measures. Any reassessment and the conclusions and implementation of control measures are documented in this Annual Report.
No additional processes or controls have been implemented to the system with regard to solid and floatable materials. A system for floatables control at the Leavenworth CSO outfall was evaluated by the design team for the proposed Leavenworth Lift Station. It was reconfirmed to the City that any proposed floatables controls in the Missouri River channel are infeasible due to the high velocities and variable characteristics of the channelized flow in the river. City staff was not able to look at additional measures of solids and floatables control at other locations in the system due to the Missouri River Flood.
Due to the flood, the current CSO screening stations at the CSO 106/107 outfall channel and at CSO 108 were removed from operation this year. It was determined that the screen at CSO 106/107 needed to be removed because the head loss through the screen was too great and would have resulted in increased flooding interior to the City during heavy rain events, with the potential to overtop the ring levee that surrounds this channel. The screen at CSO 108 was removed from service with the installation of the temporary pumping station at this location. Early indications from the USACE on anticipated river elevations with the flood along with a detailed evaluation of the hydraulic grade line at this location indicated that the station would not flow by gravity, thus the need for the temporary pumping at this location.
G. Pollution Prevention As stated in the CSO NPDES Permit, “Pollution prevention is intended to keep contaminants from entering the CSS and accordingly the receiving waters by way of the CSOs.” The CSO NPDES Permit requires the City of Omaha to document any new pollution prevention measures enacted by the City in this Annual Report.
Management of Pollution Prevention activities are shared between several Divisions and work groups within Public Works. Records for pollution prevention are maintained by the City of Omaha’s Quality Control Division. Certain details of those records are compiled and included in an annual report as required by the City of Omaha municipal separate storm sewer system (MS4), NPDES Permit NE0133698. Specifically, the MS4 annual report contains a section on Pollution Prevention/Good Housekeeping and includes a summary of storm sewer maintenance and cleaning records and street sweeping efforts.
The City also continues its outreach through the Papillion Creek Watershed Partnership and through a contract with Keep Omaha Beautiful to implement a storm water pollution prevention and public education program that also provides benefits to the CSO program. No additional pollution prevention measures have been implemented during this report period.
- 12 - ______
H. Public Notification
As stated in the CSO NPDES Permit, “Public notification is intended to inform the public of location of CSO outfalls, occurrences of CSOs, plus health and environmental effects of CSOs.” The CSO NPDES Permit requires the City of Omaha to document any revision or updates to public notification procedures in the Annual Report plus include any public announcements related to CSO discharges.
The semi-annual review of the Standard Operating Procedure (SOP) for Reporting and Public Notification of Dry Weather Sewer Overflows and Bypasses resulted in an updated list of local, regional, and downstream officials. Attachment 1 –in this report contains the current procedure. No other changes have been made to the policies or procedures for Public Notification.
Two public announcements in the form of media releases were made during the report period. The first release, on June 3rd, was to announce the bypass at Monroe Street Lift Station due to risk of the station flooding during the Missouri River Flood. The second media release was to announce additional wastewater discharges to the Missouri River due to heavy rainstorms that caused loss of several wastewater pumping locations along the riverfront and caused the disinfection unit at the MRWWTP to go out of service. The media releases are included in Attachment 2 – Dry Weather Overflow Media Releases of this report.
I. Monitoring to Characterize CSO Impacts and the Efficacy of CSO Controls As stated in the CSO NPDES Permit, “Monitoring to Characterize CSO impacts involves inspections and other simple methods to determine the occurrence and apparent impact of CSOs.” The CSO NPDES Permit requires the City of Omaha to document any additional CSOs discovered by the City during routine inspections in this Annual Report as well as that characterization of the CSS system and the impact of the CSO discharges are regulated according to the requirements in the LTCP.
Information on LTCP efforts to characterize the CSS system can be found in Section IV.A. of this Annual Report. No additional CSO outfalls were identified.
CSO Occurrence Inspections Per Combined Sewer Overflow Guidance for Nine Minimum Controls (EPA, 1995), “The municipality should record the number of CSO overflows at as many outfalls as feasible.” The City of Omaha does keep records of CSO overflow events to the extent possible. City procedure is to inspect CSO structures and devices after rain events and snow melt and record if there is evidence of an overflow. CSO devices are known to City staff to be simple physical indicators that an overflow has occurred and often consists of an object or “block” set on a weir wall that gets moved off the wall as flows cross its path. The inspections are performed and documented by the Sewer Maintenance Division with assistance from the Quality Control Division. MRWWTP and PCWWTP are responsible to recording the number of occurrences for CSO 102 and 201. This procedure did not change during the report period. However, due to the Missouri River Flood, several of the outfalls could not be monitored.
During the report period City staff completed 1,746 inspections which include routine bi- weekly checks for possible dry-weather overflows. Post rain and snowmelt checks were - 13 - ______
accounted in 1,036 of those inspections with 409 overflows recorded. CSO 102 recorded an additional 30 overflows which is reported along with the monitoring results in Section IV.A under Missouri River Wastewater Treatment Plant (MRWWTP) - Outfall 102. Table 4 below summarizes the CSO Frequency at each monitored CSO during the report period.

- 14 - ______
Monitoring of CSO Impacts Certain CSOs are sampled and water quality parameters are analyzed per the requirements of the CSO Permit Annual Report and results can be found in Section VI of this Annual Report. As per previous CSO NPDES Permit that established a requirement for implementation of this NMC, a report to record beach closings, wash-up of floatables, fish kills, hazards to navigation, and basement flooding caused by CSO events is as follows:
In the period of October 1, 2010 to September 30, 2011, there were no known beach closings or fish kills. There are no records of any wash-up of floatables. Two Media release were issued to warn the public of dry-weather discharges that occurred during the Missouri River flood. Navigation on the Missouri River was prohibited due to flooding. A total of forty-three (43) rain related backups were reported and documented by the Sewer Maintenance Division. An additional twelve (12) instances were reported where flow escaped the combined system through manholes but entered back into the combined system downstream. Most of the reports were associated with several rain events and the Missouri River Flooding event. Majority of the events were due to the 100 year rain event that occurred on August 22nd (registered rainfall between 5 to 7 inches). Letters summarizing these occurrences were submitted previously to the NDEQ.
Impacts from CSO discharges and efficacy of CSO controls during implementation of the LTCP will be covered under Section IV.I Post-Construction Compliance Monitoring Program of the Annual Report.
- 15 - ______
IV. LTCP Documentation Part V of the CSO NPDES Permit requires the City to document and submit reports showing compliance with the conditions and requirements of this section. The following addresses those requirements and is presented in the order found in the permit.
A. Characterization and Modeling of the CSO System As stated in the CSO NPDES Permit, the City of Omaha developed and implemented procedures for the characterization, monitoring, and modeling of the CSS. The measures taken as part of the development of the LTCP are described in Section 2 of the plan. As part of the development of the LTCP, the response of the CSS to various precipitation events, the number, location, frequency, and characteristics of CSOs, and water quality impacts that resulted from CSOs were evaluated.
As part of the implementation of the LTCP, the system continues to be further characterized as the projects are designed. Design Consultants are asked to review existing data and to gather additional information to form the basis of their designs. The data and designs are then included in the City’s InfoWorks model to ensure that the level of control specified in the LTCP is achieved.
The CSO NPDES Permit requires the City of Omaha to continue to characterize, monitor, and model the CSS as set forth in the LTCP and to document the measures in the Annual Report. The following is a summary of the City’s activity during this report period. Characterization Efforts Characterization efforts of the CSS can be broken down into several areas. These include:
1.) Water quality monitoring of select outfalls. - The City has been performing water quality monitoring of various outfalls since 2002. Section VI of this report details the water quality data collected from the outfalls. It should be noted that as a result of flooding in the Missouri River, outfalls along the Missouri River could not be monitored. 2.) Gathering of field data in sewer separation project areas. As part of the study phase for sewer separation projects, field data is gathered on the conditions of the CSS. Such field data includes smoke testing, closed circuit televising of sewer lines, dye testing and manhole evaluation and lamping. 3.) CSO Block Program. The City maintains a block program also commonly referred to as CSO device checks. Under this program a “block” of some type of device is placed to indicate if there is an overflow. Details of this program were previously presented in Section III, I. Monitoring to Characterize CSO Impacts and the Efficacy of CSO Control.
Monitoring Efforts
In addition to the water quality monitoring mentioned above, the City has been performing flow monitoring of its combined sewer system since 2004. Table 5 - Flow Monitoring Program is a summary of this monitoring. The most recent system-wide monitoring was done in 2010. A concentrated flow monitoring effort in the Cole Creek subbasin was performed in 2011. The installation of additional flow monitoring devices at the program level as well as at the project level is currently being considered for next year.

2011 Cole Creek Subbasin 9 Modeling Efforts A computer model representing the hydrologic and hydraulic elements of Omaha’s combined and sanitary sewer system was created to support the development of the LTCP. The software package used to model the system is called InfoWorks. This model continues to be used during implementation of the LTCP. The model is updated with information about the sewer system collected by the Project Teams and with the final designs of the controls. The model is currently being recalibrated based on flow monitoring data collected in 2010. B. Public Participation Plan The CSO NPDES Permit requires the City of Omaha to continue to employ a public participation process throughout implementation of the LTCP and document public participation activities in this Annual Report. Included in Attachment 3 – Public Participation Report is a summary of efforts during the reporting period produced by Lovgren Marketing Group.
C. Consideration of Sensitive Areas The CSO NPDES Permit requires the City of Omaha to submit a report to the NDEQ by October 1, 2014 on reassessment of overflows to sensitive areas in those cases where elimination or relocation of the overflow is not included in the LTCP. The reassessment is to be based on consideration of new or improved techniques to eliminate or relocate overflows or changed circumstances that influence economic achievability. No evaluation is required in this Annual Report. An evaluation will be included in the Annual Report covering the period of October 1, 2013 to September 30, 2014.
- 17 - ______
D. Evaluation of Alternatives The CSO NPDES Permit requires the City of Omaha to submit any significant changes or revisions to the controls, as set forth in the LTCP, to the NDEQ for review by October 1, 2014.
During this reporting period no changes were evaluated for the LTCP controls. The City is in the process of considering adjusting the original baseline schedule for the LTCP since a better understanding has occurred during implementation on the way that projects are being delivered. Any changes to the LTCP controls or schedules will be communicated to NDEQ in next year’s Annual Report.
As the projects are being designed, minor design changes have occurred to the projects from what was originally described in the LTCP. These changes are noted in the individual Project descriptions included in Attachment 4 – LTCP Project Progress Reports.
E. Cost/Performance Considerations The CSO NPDES Permit requires the City of Omaha to submit a financial report to the NDEQ by October 1, 2014; that sets forth a strategy to obtain sufficient revenue to fund the CSO program through at least the year 2020 that includes funding for the specific projects in the Implementation Schedule, Section 7 of the LTCP.
The financial report will be submitted per the requirements of the permit. For additional information on this, please refer to Section VIII – Other Information, Subsection F, Rate Information.
F. Operational Plan The NPDES Permit requires the City to update the Monitoring Program and CSO Wet Weather Operations Plan as CSO controls are constructed and sewers are separated. It also requires that a wet weather operations protocol for discharge through CSO 102 that includes operational procedures to maximize wet weather flows through this outfall, provide disinfection, and chlorination/dechlorination the NDEQ, be developed and submitted by September 30, 2015. During the report period three sewer separation projects were completed. None of these projects resulted in a change to the operations of the combined sewer system; therefore no changes were made to the CSO Wet Weather Operations Plan as a result. Therefore no update is included in this submittal. The MRWWTP Improvements are expected to be complete during the October 1, 2014 to September 30, 2015 Annual Report Period. A wet weather operations protocol will be submitted with that report as required in the permit. G. Maximizing Treatment at the Existing POTW Treatment Facilities The CSO NPDES Permit requires the City to continue to evaluate opportunities to maximize treatment at the WWTPs, meaning at the City’s MRWWTP and PCWWTP, as part of the adaptive management strategy for implementation of the LTCP. New approaches identified to maximize treatment of combined wastewater at the WWTPs are to be summarized as part of the Annual Report.

H. Implementation Schedule The construction and sewer separation projects that are designed, constructed, or are operationally completed during the current permit term have been outlined in Part VI of the CSO NPDES Permit, Compliance Schedule for Implementation of CSO Control Projects. The required progress reports on implementation of the CSO Major and Sewer Separation projects are discussed under Section V
- 19 - ______
Compliance Schedule with project summaries in Attachment 4 – LTCP Project Progress Reports of this Annual Report. I. Post-Construction Compliance Monitoring Program
Section 8 of the LTCP included the City’s Monitoring Program and CSO Wet Weather Operations Plan and a draft Water Quality Monitoring for the Implementation Monitoring Plan (IMP) was included with the CSO NPDES permit application submitted to NDEQ on March 29, 2010. The CSO NPDES permit requires that in-stream monitoring plan be conducted consistent with the draft document Water Quality Monitoring for the Implementation Monitoring Plan (IMP).
The City’s Post Construction Monitoring Program includes three types of monitoring which are:
1.) CSO Outfall Monitoring at designated CSOs, data found in Section VI
2.) In-stream monitoring, consistent with the IMP, data found in Section VII
3.) Verification of sewer separation projects will be used to confirm that the desired level of separation was achieved. The City of Omaha is using various approaches to verify sewer separation including visual verification, water quality monitoring, flow monitoring, or a combination of these approaches. The CSO NPDES Permit requires the results of studies performed that support the deactivation of a CSO point to be included in the Annual Report.
During the Report Period, sewer separation evaluations were made of two CSO outfalls. The following is a summary of the study activities of CSO 209 (44th and Harrison) and CSO 104 (Mormon Street). Further study and documentation will be completed in the next year so as to apply for the deactivation of these CSOs.
CSO 209 A post-separation study is currently being performed on the contributing area of CSO 209 upon completion of the 42nd and X Sewer Separation LTCP Project. The goal of this study is to execute the steps necessary to determine if the specified control, sewer separation and complete CSO deactivation, can be achieved, and if not, determine the potential additional work that may be needed.
The sewer service area for CSO 209 has had multiple sewer separation projects completed to remove public storm water connections and designate a separate sewer for sanitary only flows, the last one being 42nd and X Street Project (OPW 50986). Upon completion of the project, two flow monitors were installed at 41st Ave. and Madison Street to monitor the 24 inch “dry” overflow pipe and the active 12” sanitary pipe. The study began evaluating the wet-weather influence to the flows at this location at the start of the spring rain season of 2011. Potential sources of inflow and infiltration (I/I) in the sanitary sewer system were also investigated through smoke and dye testing for public and private defects; manhole investigation and inspections at critical junctions; and pipeline assessment via Close Circuit Television Inspection (CCTV) of main trunk lines. During this report period, the data from the flow monitoring showed no occurrence of an overflow. The results of the data collected will be analyzed during
- 20 - ______
the fall and winter of 2011 and used to determine the appropriate next steps toward permanent deactivation of CSO 209.
CSO 104 In 2007, a project to substantially separate the Mormon Street CSO area (CSO 104) and increase the conveyance capacity downstream to CSO 105 was completed. At the completion of this project, the CSO overflow pipe was partially bricked up. This effectively raised the weir height on the CSO overflow pipe while leaving the CSO point active to allow for a time to evaluate the effectiveness of the project. The outfall of CSO 104 was flow monitored as part of the 2010 flow monitoring efforts to serve as a post-separation verification. An area-velocity flow meter was placed on the downstream side of the CSO 104 overflow weir. The monitoring period went from 4/20/2010 to 8/3/2010 and the data for the 60” outfall pipe did show an overflow on June 1st after a rain event that had a peak 15 minute intensity of nearly 6 inches per hour. A depth of approximately 3.6 inches was recorded and this was the only overflow on record during the monitoring. This CSO outfall is checked after every rain event along with other CSO inspections and before this one event had not shown evidence of a discharge since April of 2007.
This information was provided to the City design engineering staff that has been involved with the projects in this area. The hydraulic grade line has been modeled for the area contributing to this CSO and a preliminary assessment that permanent closure of the CSO would have no repercussions on properties or public health as a result. The information on this overflow event and other data gathered from the flow monitoring study along with an assessment of the remaining sources of inflow in the sub-basin will be evaluated by City Engineering or an outside consultant to determine if additional inflow removal is required to deactivate this CSO.
- 21 - ______
V. Compliance Schedule The purpose of this section is to provide information on the status of the implementation of the LTCP as required both in the City’s CSO Permit and the Consent Order (August 8, 2007, NDEQ Case No. 2710) issued to the City of Omaha as well as the status of the individual or “component projects.” It should be noted that because the City has been provided the ability to allow projects to move within the Phases, delays in a project do not result in the delay of the overall implementation of the LTCP. Where dates have not been met, the City has documented the reason for the delay and the mitigation taken to bring the project on schedule. This documentation is referred to as “Change Notifications Requests” and is included in Attachment 5.
A. Project Implementation Part VI of the CSO NPDES Permit, Compliance Schedule for Implementation of CSO Control Projects, states, “Upon issuance of this permit, the City of Omaha shall implement the compliance schedule below for construction projects set forth in the Long Term Control Plan (LTCP). This schedule may be modified in accordance with NDEQ Title 119 and written notice from the NDEQ. The City of Omaha shall include a yearly summary of construction activities, actions, and other measures applicable to this compliance schedule in the Annual Report”. In addition, to compliance with the permit, this Annual Report must meet the reporting requirements as specified in the Complaint and Compliance Order by Consent (or Consent Order). These requirements are: a. A statement identifying each component project time frame in the period preceding the initial, or thereafter, the most recent previous report, calling for commencement, completion, implementation or some other action to be taken, and whether and to what extent such action was taken by the City within the respective component project time frame. b. A general description of the work performed pursuant to the LTCP and component project time frame schedule for the period covered by the report and whether it conformed to the LTCP and time frame schedule. c. A statement of any future planned or expected deviations from the LTCP and component project time frame schedule and the reasons for such deviations.”
The tables that follow address the above requirements included in the Permit as well as those on Page 9, items a and c of paragraph 29, of the Consent Order. The general description of project component activities as required in item b of paragraph 29 of the Consent Order can be found in Attachment 4 – LTCP Project Progress Reports
The information on these projects is divided into Major Projects and Sewer Separation Projects and summaries are provided in the tables below to show the actions planned and executed during the reporting period. A brief statement of their compliance with these dates, or mitigation to reach compliance is also provided. As stated above, where dates have been not been met, Attachment 5 should be consulted as it includes the Change Notification Request
- 22 - ______
(CNR). These provide documentation on the cause of the missed date and the measures taken to bring the project back in schedule.
The following definitions were used for Table 6 through Table 10 and are taken from the Permit with some elaboration provided for this report:
• Bid Year – The year when the bidding process for a specific project is started. This will be noted in the tables below as “bidding” date and corresponds to the day the project was advertised. This only applies to Sewer Separation Projects. • Begin Final Design – The date when a Notice to Proceed is issued to a design consultant, or in the case of a design that is completed by City staff, the date when work is started by City staff. • Commence Construction – The date the Notice to Proceed is issued to the contractor. • Complete Construction – When sewer separation project is substantially complete. • Operationally Complete – When a Major CSO project is substantially complete, is ready for its intended use, and has been made ready to operate by the City. For Sewer Separation Projects in general the “complete construction” and “operationally complete” will be the same date.
Other dates and corresponding actions listed in the tables below, such as “Study” and “Start Preliminary Design”, are part of the LTCP schedule, but are outside of the permit requirements. These dates are provided to demonstrate that activities that have been taken on projects.
Major Projects Compliance with the schedules as outlined in the permit for Major Projects Phase 1 through Phase 3, is demonstrated below in Table 6 to Table 8
Part VI. A of the permit, “Schedule for Phase 1 Major Projects of the LTCP” requires that the five (5) projects listed in Table 6 below be operationally complete by September 30, 2015. The table shows that these projects are currently on schedule to meet this date.

For Phase 3 Sewer Separation Projects, the current permit requires the City to initiate the bidding process on at least one of the six projects listed in the permit on or before December 31, 2014. Phase 4, 5A, 5B, 6 and milestones and compliance dates are not in the current CSO NPDES Permit Sewer Separation Projects. However as part of schedule tracking, if the planned schedule for activity falls within the report period, it will be reported in this Annual Report. The table below lists two Phase 3 projects and one in Phase 4 project that that had activity this report period.

B. LTCP Overall The Consent Order in Paragraph 29 item b, requires that as part of the Annual Report the City provide, “A general description of the work performed pursuant to the LTCP and component project time frame schedule for the period covered by the report and whether it conformed to the LTCP and time frame schedule.” This section addresses the overall status of the LTCP implementation.
Schedule Over the last year the City has continued to implement projects and to work toward meeting the 2024 deadline. Table 11 lists the overall status of the Phases described in Tables 7-1 and 7-1 of the LTCP. As shown in the table, the Project Phases are on time or slightly ahead of schedule. The only exception to this is Major Controls Phase 3, which is showing that the start of final design is late. This is the result of a delay in contracting of the Design Consultant. This does not affect the date for completion of construction. In addition the date missed is not a permit date that is included in the City’s CSO permit.

Figure 1 is a graphic representation of the projects status. As noted in the figure, the 87 original projects that were listed in the LTCP are currently being implemented through 105 contracts having Omaha Public Works (OPW) numbers. Out of that number, 36 are completed or underway. The pie chart illustrates that eight projects have tasks such as final design that are currently behind schedule, but are still on track to complete construction on schedule. Only one project, Aksarben Village Phase A, is currently scheduled to finish construction behind schedule; however, the construction contractor for this project has indicated that it might still be possible to complete construction on time. The late projected completion date for Aksarben Village Phase A is due primarily to start of construction timing (late fall) and the growth in the magnitude of the sewer work required to accomplish its objective. It is believed to be likely that Aksarben Village Phase A will accomplish the objectives of both Phase A and Phase B in terms of inflow reduction. The delay does not affect permit dates.

- 27 - ______
The City is continuing to adapt to issues that have arisen through implementation of the program. One particular challenge that is being addressed is impacts caused by Missouri River Flood during the summer of 2011, as noted elsewhere in this report.
Costs The City developed various tools to track the costs of the implementation the LTCP projects. Controlling costs is important to ensure that the program continues to be as affordable as possible for the people of Omaha, and to allow the LTCP schedule to be maintained. The cost of the program continues to range around $1.7 billion. However, it has become apparent that funding may be of concern in the short term as the result of costs associated with increased opinions of probable cost of Phase I Major CSO projects. While this should not result in the ability of the City to meet with LTCP completion date of October 1, 2024, it may have an impact on the ability to meet the September 30, 2015 milestone date for Phase I Major CSO projects. Efforts are being made to reduce the impact of these costs, including the potential delay of some projects in Phases 2 and 3.

VI. CSO Outfall Monitoring Data The CSO NPDES Permit in Part II and Part III requires the monitoring of the MRWWTP outfall 102 and other selected CSO outfalls (105, 106, 107, 108, 202, and 205). Certain samples were prevented and discharges could not happen due to the Missouri River Flood. Figure 2 is a map showing the locations of the required CSO monitoring. A summary of the data is in the following sections.
Figure 2: CSO Monitoring
- 29 - ______
A. Missouri River Wastewater Treatment Plant (MRWWTP) - Outfall 102
The Interim Requirements for CSO Outfall 102, as defined in Table 3, Part II of the NPDES Permit, are in effect for this Permit year. The conditions for approved bypass of combined sewer were complied with these requirements.
There were 30 overflow events at CSO 102 from October 1, 2010 through September 30, 2011. Results from these events are reported on quarterly discharge monitoring reports. Polychlorinated Biphenyls and Dieldrin were tested on June 3, 2011 with none detected for each pollutant. CSO Outfall 102 was entirely closed from June 6, 2011 through October 5, 2011. This resulted in no overflows from CSO 102 in July, August, or September of 2011.
The data for CSO 102 has been summarized in Table 12. The value reported for Flow Rate is the average flow rate of all of the events in the reporting period. The value reported for Total Flow is the total of all of the events in the reporting period. The value reported for Duration of Discharge is the total of all of the events in the reporting period. The value reported for Total Suspended Solids is the average concentration of all of the events in the reporting period. The value reported for Biochemical Oxygen Demand is the average concentration of all of the events in the reporting period. The value reported for Dieldrin is less than 0.0001 mg/l, which is the analysis detection limit. The value reported for Polychlorinated Biphenyls is less than 0.001 mg/l, which is the analysis detection limit. The value reported for E coli is the average count of all of the events in the reporting period. The values reported for pH are the maximum and minimum values of all of the events in the reporting period.

- 32 - ______
The in-stream monitoring is managed by the City of Omaha Quality Control Division to provide for the requirements of the CSO NPDES permit but also to meet the requirements of the City’s MS4 Permit. The Annual report for the MS4 Permit is submitted for the period January 1 to December 31. The data for the sites collected by City staff (MR 1, MR2, MR5, CC1, CC2, LPC3, BPC3) were analyzed through MRWWTP Lab are included in this report. These sites were sampled in accordance with the Implementation Monitoring Plan in 2011 with the exception of the Missouri River sites in June and July due to high river levels. The remaining three sites (LPC1, BPC4, PC1) were sampled weekly from May through August and once in September by way of a contract with University of Nebraska at Omaha (UNO). The samples will continue monthly for the remainder of 2011. See Figure 3 for approximate locations of the in-stream monitoring sites.
The samples collected and analyzed by City Staff are reported below in Table 14. The values displayed for BOD for Season 1, dry sample have been reported by the laboratory in brackets to indicate a best educated guess that did not meet quality assurance requirements. Obtaining accurate BOD results requires some predictive aptitude when choosing BOD dilutions. Since the dry weather samples of Season 1 were the first of these sample types obtained, the lab did not know what strengths to expect. The lab used a dilution range that had been successful with other CSO samples in past years, but those dilutions ended up being too dilute. When BOD dilutions are too dilute, oxygen deletions are insufficient to meet the quality assurance standards. The result of [3] mg/L is just above the detection limit for the BOD test is 2 mg/L.
Results for the samples collected by UNO are expected in December 2011. These along with the in-stream sample reported in this CSO Annual Report will be incorporated into the MS4 Annual report for 2011 and submitted to the NDEQ April 1, 2012.

VIII. Other Information The CSO NPDES Permit, Part VII.F suggests that the City should include in the annual report, other information that may address “measures of success” for the Program such as reduction in the number of overflow events, reduction in the number of CSO outfalls, or other indicators or improvements of receiving water quality. This year’s report also includes information in this section on the Missouri River Flood of 2011 and its effects on the CSS, as well as the City of Omaha’s RNC program, and a discussion on rates and the City’s ability to pay for the program. At the request of the NDEQ Waste Management Division, a paragraph will be included in this section each year that discusses contaminated soils that are encountered during the construction of capital projects associated with the CSO Program. A. Missouri River Flood In 2011 record amounts of snowpack and rainfall in the upper Missouri River Basin resulted in runoff that exceeded the capacity of the five reservoirs that are managed by the U.S. Army Corps of Engineers (USACE). With no available capacity to store the inflows into the system, the USACE had to release the water downstream, resulting in excessive and prolonged flooding in the Omaha area. The flooding greatly impacted the city’s ability to maintain the portions of the CSS and at times impacted the city’s ability to deliver flow from the CSS to the treatment plants. The City communicated with the NDEQ early, on a frequent basis and later as situations arose inform on the impacts to the CSS and the WWTPs. The flooding resulted in a prolonged upset condition to the City of Omaha’s treatment and collection system, with conditions varying throughout the flood due to many factors, including rainfall, river levels, and elevated groundwater tables. This section describes the events that lead to the Flood of 2011, the magnitude and duration of the flooding in the Omaha area, the impacts to the CSS, the City’s ability to deliver flows to the WWTPs, and reactionary measures taken by the City to maintain the system to the extent possible while attempting to protect the citizens of the City of Omaha, and public and private property. Additional information on the impacts of the Flood on the City’s ability to operate, maintain, and manage the CSS along with its ability to meet requirements of the CSO NPDES Permit have been included throughout the report where appropriate. The Missouri River Flood of 2011, referred to hereinafter as “the Flood”, was the result of a greater than normal snowfall which occurred late in the season in the Northern Rocky Mountains, followed by excessive amounts of rain in May and June in the Upper Missouri River Basin states of Montana, and North and South Dakota. The USACE manages five mainstem reservoirs in the upper Missouri River basin. The primary purpose of these reservoirs is flood control. The USACE has been maintaining monthly records of runoff, measured in millions of acre-feet (MAF) since 1898. The late season snowmelt coupled with the excessive amounts of rain produced 3 of the 5 highest monthly totals of runoff ever recorded, with May runoff at 10.5 MAF, June runoff at 13.8 MAF, and July runoff at 10.0 MAF. The combined total runoff from May through July of 34.3 MAF exceeded the normal yearly runoff to the system by nearly 40%. The current forecasted total runoff for the year of 61 MAF is approximately 240% of normal, and nearly 25% greater than the previous record runoff of 49 MAF, which occurred in 1997. Runoff from the basin coupled with water already in the reservoirs exceeded the 72.8 MAF of storage capacity, causing the USACE to increase flows released from Gavins Point, the downstream -most reservoir in the system, to a rate of 150,000 cfs, nearly double the previous
- 35 - ______
record release rate. (Additional rains in South Dakota that occurred in June resulted in the flows to be increased to 160,000 cfs.) The USACE informed the City of Omaha that flooding resulting from these flows would be significant, and would be sustained for a long duration. The City of Omaha utilizes a gauge at the I-480 Bridge as the official gauge for recording river elevation and flow rate. Flood stage at this guage is 29 ft. The City was notified to prepare for elevations of 34 feet to 36 feet, well in excess of the 100 year event. On May 31, 2001, the gauge registered an elevation of 29 feet, and the City of Omaha declared that a flood event was occurring. On June 21, 2011, the 100 year flood flow of 174,900 cfs was exceeded, at an elevation of 34.7 feet. The 100 -year flood lasted until August 8, 2011, a total of 47 days. Two intermediate crests of 36.29 feet on July 2, 2011 and 36.1 feet on July 24 occurred during this time. On September 10, 2011, the river finally fell below 29 feet. This resulted in a total flood event duration of 114 days as defined by the 29ft. elevation Following is a list of major items related to the CSS, the City of Omaha’s ability to deliver wastewater flows to the WWTPs through its CSS, measures taken by the City to convey and treat as much flow as possible, and measures taken to protect and maintain its wastewater infrastructure. Please note that this is not a list of all items. Reportable items are listed where appropriate in this report.
• The southern portion of the MRWWTP is not protected by the City’s flood control levee. A temporary earthen levee approximately 2100 feet in length was constructed to protect this infrastructure. This allowed for the City to continue primary and secondary treatment of flows that were conveyed to the plant.
• Due to flooding of the Monroe Street Lift Station, the City of Omaha closed the isolation gates at the diversion structure on June 3, 2011 and returned to regular service on October 1, 2011. This action resulted in a bypass of up to 10 cfs of untreated wastewater to the river. Standard procedure on public notification was followed and a press release was issued at the time.
• As the river rose, the bulkhead gates were closed to prevent river intrusion, dry weather overflows, and flooding of the river back through the levee and internally into the City. Because the bulkhead gates were closed off, the CSS and many of the CSOs could no longer flow by gravity. Temporary pumping stations were set up to pump combined sewer overflows over the levee at CSO 106/107 - North Interceptor /Grace, CSO 108- Burt Izard, 121-Jones St, CSO 110-Pierce, CSO 111-Hickory, CSO 115-Riverview, and CSO 117-Missouri Ave. 96 pumps were installed throughout the City and its treatment plants during the flood, with many of these installed to help convey and evacuate combined flows.
• The MRWWTP and the PCWWTP could not follow standard wet-weather procedures and discharge through the permitted CSOs during the flooding event. The MRWWTP was not able to utilize CSO 102 from June 6, 2011 through October 5, 2011. The PCWWTP would not have been able to utilize CSO 201 in the event it would have been needed due to the elevation of the river.
• Modifications were made to the collection system to increase the amount of storm water detention and to take flows away from areas where pumping is required. This included - 36 - ______
adding temporary weirs in the system to take flows away from CSO 106/107 and direct them to CSO 105- Minne Lusa. Modifications were also made to orifices at the Lake James and Fontenelle detention facilities to retain more storm water.
• A number of sewer collapses occurred in the area of the city that was affected by the high groundwater table due to the flood. Some of these collapses were repaired on a temporary basis, with permanent repairs still waiting to be made at the time of this report. In addition, the City plans to conduct investigations of its system in areas that were affected by the flooding to ensure that the system is intact and performing adequately.
• On August 22, a rain event that exceeded the 100 -year frequency occurred, with measured rainfall totals of 5 to 7 inches falling in a 3 to 4 hour period over the eastern third of the City. The temporary pumping systems along the levee were greatly overwhelmed, and substantial flooding occurred in low areas adjacent to the levee. At one point nearly all conveyance of flows to the MRWWTP was rendered inoperable. Substantial damage and total loss of electrical systems and equipment at the Hickory, Pierce, and Riverview stations rendered these stations inoperable for an extended period of time. As stated in the introductory paragraph to this section, the previous information does not include all reportable information related to the Flood. Those parties responsible for reporting of information related to the Flood include the CSO Program and the WWTP’s. Additional information has been provided in this report or may be obtained by contacting the City of Omaha Sewer Maintenance Division, Quality Control Division, and the Missouri River and Papillion Creek WWTP’s Divisions. B. Reduction in the Number of Overflow Events During the City’s required implementation of the NMC several years prior, substantial improvements were made to the City’s O&M procedures relating to the CSO outfalls. Because of this, dry weather overflows at the CSO outfalls showed immediate reduction at that time. There is still a slight trend downward in number and at the same time the City has become more thorough in the record keeping process. The City continues to evaluate its O&M procedures, as mentioned previously in this report. Staff members responsible for the O&M look for ways to improve efficiency, reliability, and standard procedures in order to continue to reduce the potential of an unintended overflow or bypass.
As shown in above in Table 2 of this report, not counting the five (5) records related to the Missouri River flooding, there are seven (7) dry weather overflows that occurred. When compared to the same time period the year prior, 10/1/2009 to 9/30/2010, which had ten (10), one could conclude that overall, the City did have a slight reduction in dry weather overflows.
The 42nd and X Street Sewer Separation Project, constructed in 2010 included work to allow for the deactivation of CSO 209. Records prior to the construction of this project indicate an average of 22 overflows per year (averaged based on data collected by the City from 10/1/2007 to 9/30/2010). In 2011, zero overflows were recorded at this location, thus showing a significant reduction.
- 37 - ______
C. Reduction in the Number of CSO Outfalls No CSO outfalls were deactivated during the report period. However, two CSOs are being evaluated for permanent deactivation. CSO 209 and CSO 104 have had previous sewer separation projects. The area contributing to the CSOs have undergone some evaluation and monitoring and efforts are discussed in more detail in Section IV.I. Post-Construction Compliance Monitoring Program.
For CSO 209, as stated in the previously in this report, no flow data or City CSO occurrence inspections cited an overflow at this point during the report period. The 42nd and X Street Sewer Separation Project was the last planned separation project prior to the goal of deactivating of CSO 209. However, the data from the post-separation study will be assessed further to gain confirmation on the effectiveness of the separation project, and if additional inflow control or sewer system rehabilitation is necessary to achieve the deactivation of the CSO.
CSO 104 is also being evaluated for deactivation in the near future. At the completion of a project in the area of CSO 104 in 2007, the CSO overflow pipe was partially bricked up to allow for further evaluation before deactivation. A review of the CSO occurrence records indicated a reduction in CSO events at this location from 9 in 2007 to 1 in 2008 (this singular event may have been falsely triggered by the construction activities in the area). No overflows were recorded by the City crews in 2009. As a part of the 2010 flow monitoring study, one overflow event was recorded. Even with this overflow, it should be noted that the hydraulic grade line in the sewer still remained well below any structures. As with CSO 209, addition confirmation will be gathered as necessary to achieve the deactivation of the CSO. D. Receiving Water Quality The City monitors the receiving water quality of the Papillion Creek and the Missouri River as detailed in the Implementation Monitoring Program submitted to the NDEQ as a part of the CSO LTCP. The program is coordinated with stream monitoring that is a part of the City of Omaha’s MS4 Program. At this time, the City does not have sufficeint data to establish a trend in the Papillion Creek watershed. Trends in the Missouri River will be much more difficult to show as many more factors outside of the City’s control are not quantified or modeled at this time. As stated previously in this report, the in-stream monitoring of the Missouri River was not able to be completed due to the Flood. The City also monitors selected CSO outfalls as a requirement of the permit. In 2011, the CSO sites along the Missouri River were not sampled. Figure 4 shows the total suspeded solids (TSS) over the past 6 years, along with 2011 data. Figure 5 shows the values for E.coli for the same sampling period. As can be seen in the charts, the data that has been gathered is very random in nature. Part III of the CSO NPDES permit states that the “City may propose alternative monitoring locations to replace the CSO outfalls listed” and that the “proposed changes may be impemented without a permit modification if approved by the NDEQ.” The City will continue to evaluate the usefullness of the outfall monitoring program and the data that is being collected to understand its effectiveness in determining improvements to the water quality of the receiving streams.

This last presentation in Figure 6 is an update to Figure 7.3 , shown on Page 7-20 of the CSO LTCP. The graph displays the anticipated reduction of the loading of E.coli due to the CSO’s as the LTCP is implemented. Currently, very little reduction in the loading of E.coli is anticipated. It should be noted that at the completion of the Phase I Major Projects, a significant amount of E.coli reduction will be achieved. Figure 6: E.coli Reduction over LTCP implementation
E. City of Omaha RNC Program The City continues a program, referred to as the RNC (renovation of combined sewers) Program, to separate combined sewer areas, in addition to the LTCP projects, to primarily address basement backups. This program is managed separately from the CSO Program, however crossover of procedures, plans, standards, and guidance documents occurs between the two programs. RNC projects are also closely coordinated with the CSO Program Projects. Wherever possible, the City includes measures with these RNC projects to help achieve the goals of the CSO program, including reduction in frequency, magnitude, and duration of overflows, and ultimately the improvement of water quality.
- 40 - ______
F. Rate Information In June of 2009 the City adopted a rate ordinance that provided for significant annual rate increases for the years 2011 through 2014. Figure 7 below shows that for a typical residential household these increases are greater than 20% per year. Commercial and industrial customers will also see significant increases, and this year the City heard grave concerns expressed by its largest customers that rate increases could drive businesses out of Omaha. The City continues to work with these stakeholders to explore alternate rate model philosophy, but no acceptable alternative has yet been identified.
Figure 7: Average Residential Sewer Fee Increase
A recent review of net rate receipts shows that incoming revenues for the last two years have exceeded our modeled revenue requirements. However, for the first nine months of 2011, receipts are 7% short of revenue requirements. The City will be watching this situation closely. If it appears that there is trend of revenue shortfalls, the City will investigate the cause(s) and work to mitigate the revenue shortage. Beginning in 2011 customers that qualify for energy assistance will also receive a utility bill credit to help with rising sewer fees. The City also plans to work with local utilities and state agencies to review the existing utility assistance programs and look for ways to improve or enhance assistance to low and fixed income customers. The City’s sewer revenue fund financial plan currently extends past 2024 and includes rate revenues for CSO to match those estimated in the LTCP. The plan relies heavily on revenue bonds to finance the CSO capital improvements. The City is currently planning to sell another $75M in bonds in the fall of 2011. In 2012, the City plans to initiate an update to the financial plan and draft a rate ordinance that would be taken to the City Council in 2013. We expect this updated plan will provide specific rates for the period 2015-2018. Part V. Section E of the CSO NPDES permit requires that the City submits to the NDEQ by October 1, 2014 a “financial plan that sets forth a strategy to obtain sufficient revenue to fund the CSO program through at least
- 41 - ______
the year 2020”. The City believes that a plan with specific rates that would be ratified by ordinance through the City Council along with a schedule of proposed rates to continue to fund the program through its entirety would satisfy this requirement. G. Material Management At this point in time, no contaminated soils have been encountered during the construction of capital projects associated with the CSO Program. The City will monitor and track contaminated soils and use this report to update the NDEQ Waste Management Division.

TASK DESCRIPTION Reporting on and preparing necessary public notification of a sanitary sewer bypass or dry weather combined sewer overflow.
PROCEDURE - GENERAL
The City’s NPDES permits require reporting of any bypasses of the sanitary system or at the treatment plants as well as any dry weather combined sewer overflows to the Nebraska Department of Environmental Quality (NDEQ) Regional Office within 24 hours of becoming aware of such an event. The City of Omaha Public Works Department requires that this Initial Notification be made as soon as possible to the NDEQ Regional Office after the time of discovery for all events, with verbal (telephone) notification required for those bypasses that reach the Waters of the United States. Verbal notification of bypasses not reaching Waters of the United States shall be at the discretion of the Division that discovers the bypass. The NPDES permits also require public notification of events that are likely to cause an
2 adverse impact to public health or the environment. Finally a follow-up letter must be submitted to the NDEQ Headquarters within 5-7 days of the event.
PROCEDURE - DETAILED
1) In the event of a dry weather overflow, basement backup, or bypass, the employee(s) responding to the incident should gather information and complete an Unscheduled Bypass Memorandum form (see Attachment 1). This form may be completed by hand, by using the MS Word File (P:\CSO\CSO_SSO SOPs\Notif1_Unscheduled_Bypass_Memorandum.doc) or by using the BYPASS TRACKING DATABASE. Instructions for authorized users to obtain a copy of the database are in Attachment 7.
2) The Unscheduled Bypass Memorandum shall be emailed, faxed, or verbally phoned into the NDEQ Field Office representative listed in Attachment 2. (See Paragraph 10 to determine if verbal (telephone) notification is required.) This shall serve as the Initial Notification to the NDEQ. The Initial Notification shall be made as soon as possible and at all times must be made within 24 hours of the discovery of the event.
3) Initial Notification shall be made by the Quality Control Division (QCD) Manager, Sewer Maintenance Division Manager, Sewer Maintenance Engineer III, Sewer Maintenance Foreman III, or other responsible designee of the Environmental Services Manager. Attachment 3 lists those employees currently holding those positions identified above. When the persons listed are not available, the employee gathering the information is responsible for making the Initial Notification. If the bypass warrants verbal notification and the NDEQ Field Office representative is not available, a voice mail message will satisfy the requirement.
4) A copy of the completed Unscheduled Bypass Memorandum form should be forwarded by fax or email to at least one of the following personnel: the Environmental Services Manager, the Sewer Maintenance Engineer III, or the Designee of the Environmental Services Manager. If verbal notification was a requirement for the incident, the individual who made the verbal notification is also responsible for emailing or faxing a copy of the completed form to the NDEQ Field Office.
3 5) The Environmental Services Manager will generally be responsible for evaluating the need for and drafting any news release for notification to public of an overflow or bypass event. In his or her absence this responsibility will pass to the Sewer Maintenance Engineer III, QCD Manager, or next to the Division Manager whose staff has the lead role in eliminating the overflow or bypass or other responsible designee of the Environmental Services Manager.
6) Determination of the need for a news release will be on a case-by-case basis and may be made in consultation with the NDEQ and the Douglas County Health Department. Factors alone or in combination that support the need for a news release include the following:
• the anticipated duration of the incident – is an overflow or bypass likely to continue for 24 hours or more?
• the estimated quantity of wastewater discharged – is the quantity expected to exceed 100,000 gal?
• the nature of the overflow – does the wastewater likely contain pollutants in concentrations presenting an imminent threat to health or the environment?
• the location of the overflow – is the release in an area that cannot be secured or is likely to cause adverse impacts on health or the environment?
7) When a news release is needed, the person responsible for drafting the release will use the general format provided in the Unscheduled Bypass News Release template provided as Attachment 4.

News Release for Wastewater Discharge to the Missouri River
Contact - Marty Grate, OPWD, (402) 444-5225 Email: [email protected]
Due to high water levels in the Missouri River, today the City of Omaha is closing isolation gates to the Monroe Street Lift Station. This action will result in a bypass of approximately 10 cubic feet per second of untreated wastewater to the river.
Until the river level drops below flood stage, the Omaha Public Works Department is issuing the following advice:
Avoid wading, swimming, and other primary body contact with the waters of the Missouri River in the area near and several miles downstream from the Veterans Memorial Bridge in South Omaha.
This advisory will remain in effect until further notice.
Office of the Mayor 1819 Farnam Street, Suite 300 Omaha, Nebraska 68183-0300 (402) 444-5000 (402) 444-6059 City of Omaha Jim Suttle, Mayor Media Advisory Wastewater Discharge to the Missouri River
There will be a flood briefing at 10:00 AM on Wednesday, August 24. The briefing will take place in the Mayor’s Media room on the 3rd Floor of the City /County Building to provide a flood status report and answer questions.
In early June, due to high water levels in the Missouri River, the City of Omaha closed isolation gates to the Monroe Street Lift Station. This action resulted in the bypass of approximately 10 cubic feet per second of untreated wastewater to the river.
At that time the Omaha Public Works Department issued the following advice:
• Avoid wading, swimming, and other primary body contact with the waters of the Missouri River in the area near and several miles downstream from the Veterans Memorial Bridge in South Omaha. • This discharge is ongoing, until the water recedes and repairs can be completed. • This advisory remains in effect and is being extended from the Mormon Bridge on the north to several miles downstream from the Veterans Memorial Bridge in South Omaha.
The heavy rainstorms early Monday morning resulted in a loss of wastewater pumping capability at several locations along the river front. Also out of service is the disinfection unit at the Missouri River Wastewater Treatment Plant, located just South of Veterans Memorial Bridge. Additional damage assessments are ongoing.
The City also is issuing reminders that the public access to the City levees remains closed and under continuous security monitoring. Also, the US Coast Guard has closed watercraft access to the Missouri River unless specific authorization is obtain by the Port Authority.
If you have any questions please call me at 680-9544.

Project Activities and Progress The following is a brief synopsis of project activities and progress that has taken place during this period:
• Preliminary design (30% design), Basis of Design Report completed October 2010
• Final Design (60%) Design (Plans and Specifications) completed March 2011
• Final Design (100%) Design (Plans and Specifications) completed June 2011

• Notice to Proceed to Contractor for construction on September 29, 2011. Anticipated Project Activity for Next Period • Construction of the project is scheduled to start in October 2011 and continue through the balance of the period through September 30, 2013. Changes from the LTCP During the period no changes were made that substantively affected the project outlined in the LTCP. The following changes were made from the initial concept for the project:
• The original concept anticipated the entire storm sewers in the project area would be routed to the existing storm sewer at 63rd Street in the southwest corner of the basin. During the project development a concept was identified to route the storm sewers in the north part of the area to a new outlet to Elm Creek. The new concept includes a Green Solutions facility in Elmwood Park that includes bio retention facilities. The final design utilizes the 63rd and Shirley outlet and a new outlet to Elm Creek in Elmwood Park. This change reduced the potential cost of the project, avoided the need to construct sewers parallel to existing storm sewers, and allowed for the implementation of the Green Solution referred to as the “Elmwood Diversion”.
• Originally Aksarben Village Phases A and B were scheduled to be staggered in time. However, based on field investigations for the Phase A project, it was concluded that the existing sewers are in good enough condition to remain in place without further rehabilitation as planned in Phase B. Therefore, Phase B is believed to be no longer needed. If, in the future, additional I&I reduction is warranted (Possibly to improve the performance of the CSO 205 RTB), the City will reconsider the need to conduct all or a portion of the Phase B rehabilitation at that time.
• Overall the cost of the project is higher than that in the LTCP. Other Items of Interest None at this time.

Project Information LTCP CSO Control Project Name: CSO 211 Sewer Separation Project
LTCP Project Description: Refer to the LTCP for more detailed information. A brief summary of the project is as follows:
The intent of this project is to provide sewer separation for a small portion (8 acres) of the Papillion Creek North Basin. This project includes construction of both sanitary sewer and storm sewer to allow for conversion of the existing combined sewer to either storm sewer or sanitary sewer as appropriate. This will result in reduced combined sewer flows to the CSO diversion structure at South 66th and Pacific Streets and ultimately to the proposed Saddle Creek Retention Treatment Basin proposed near 64th and Dupont Streets. It should be emphasized that the CSO 211 diversion structure and overflow pipe will not be eliminated as part of this project. Overflows from the diversion structure are caused primarily by infiltration and inflow from the contributing area to the large interceptor sewer running through Elmwood Park. The diversion structure and overflow pipe will not be eliminated or plugged until a relief sewer is constructed downstream of this diversion structure or when infiltration and inflow have been sufficiently reduced on the large interceptor sewer.

Project Activities and Progress The following is a brief synopsis of project activities and progress that has taken place during this period:
• This project is located in an area along Pacific Street which will eventually be widened. Options were explored to provide funding sources to widen Pacific Street while the sewer separation work would be commencing. The funding was not available prior to Fiscal Year 2014, so the Pacific Street widening element has been currently withdrawn. Inlets that currently connect to the combined sewer within Pacific Street will still be separated, regardless of the widening being eliminated. Anticipated Project Activity for Next Period • Begin preliminary design and progress to 30% plans development. Develop green solutions alternatives analysis, which will determine the location of storm sewer outlet. Changes from the LTCP During this period, no changes have been made to the overall project schedule from the project schedule in the LTCP. Other Items of Interest Construction of a rain garden green solution in Elmwood Park is a possibility that will be explored. CenturyLink currently operates a major communications duct line within Pacific Street that will require possible shifting or relocation to accommodate the sewer separation work.

• Complete bidding and award and start construction on Contract 2 in Spring/Summer 2012 Changes from the LTCP During this period, no changes have been made to the overall project schedule from the project schedule in the LTCP. The following changes from the LTCP have occurred for this project: 1. The location of the lift station was shifted west of the potential locations identified in the LTCP because of property acquisition constraints. The Quaker Oats site was chosen from the two options shown in the LTCP. The relocation west increased the ground surface elevation, and subsequent depth of the lift station. Rock was determined to be present at the site at a higher elevation, which has increased the current engineer’s estimate for the project. 2. Leavenworth Lift Station Replacement project has been divided into two contract packages.
• Contract 1 consists of preliminary sitework required to prepare the site for OPPD’s relocation of high voltage power lines. The reason for the early sitework preparation package centered on OPPD’s schedule requirements for the high voltage power line relocation. Demolition of existing buildings north of Pierce Street(including remediation efforts) and preparation of the west end of the site need to be complete before the utility can relocate their services, This work needs to be done before the late April through May 2012 timeframe scheduled for relocation. OPPD had indicated that missing this
LEAVENWORTH LIFT STATION_ANNUAL_PROJECT_PROGRESS_REPORT__21SEPT2011.DOCX 2 CITY OF OMAHA COMBINED SEWER OVERFLOWS NPDES PERMIT NO. NE0133680 ANNUAL REPORT OCTOBER 1, 2010 THROUGH SEPTEMBER 30, 2011
window would mean relocation would be pushed back to fall, after the high electrical service demand period. This, in turn, would impact project schedule. Thus, an early site preparation package was required.
• Contract 2 will include the new lift station and the diversion structure at the Existing Leavenworth Sewer Site. 3. The lift station capacity has been increased from 43 to 45 MGD to facilitate reasonable flow capacity of each of the main pumps. The station has three, 15 MGD duty pumps and one 15 MGD standby pump for pumping Wet Weather flows. 4. No odor control is being provided. The exhaust air system is being ducted to allow reasonable transition of odorous air to a separate odor facility that will be constructed on site at a later date if required. 5. Two sewers will provide flow to the new Leavenworth Lift Station. One will be coming from the north and its flow will consist of intercepted flow from the Existing Leavenworth Sewer through a newly constructed diversion structure. The second sewer’s flow will consist of flow coming from the south from the Hickory and Pierce Street systems. 6. No floatables control will be installed for the CSO outfall as part of this project. During design the Project Team did evaluate various controls. However, they provided to be infeasible because of the flows anticipated through the structures prior to construction of the tunnel. Further evaluation of some lower cost controls had to be eliminated because of the flooding of the Missouri River. The floatables control will be integrated into subsequent projects related to the Leavenworth CSO outfall. Other Items of Interest Recent flood conditions have resulted in several joint separations in the Existing Leavenworth Sewer. Field investigations will be conducted in late October or November 2011, as river level allows, to determine whether the planned flow diversion structures can be reliably integrated into the 80 year old infrastructure to allow flow to be diverted south to the new lift station. Determination of the sewer’s realistic service life will also be made.

1. MRWWTP Improvements Project has been divided into two bid packages due to impacts related to high river levels in 2010 and 2011. The two packages are referred to as Schedule A and Schedule B. a. Schedule A includes separate primary treatment of the high strength waste from the South Omaha Industrial Area (SOIA), modifying the Transfer Lift Station, and providing a non potable plant water system. Start of construction for Schedule A is targeted to meet LCTP Commence Construction date, listed previously in this report. b. Schedule B includes addition of a new headworks and modifying the municipal preliminary and primary treatment facilities to accept a sustained peak hour flow of 150 mgd and to provide chlorination and dechlorination of the CSO 102 effluent prior to river discharge. The start of construction for Schedule B is anticipated to be in the Spring of 2013. 2. For the high strength industrial wastewater conveyed to the plant, the LTCP identified peak instantaneous flow (peak wet weather capacity) of 18.3 mgd based on a 25 year/24 hour storm event. Current design of the SOIA conveyance utilized a 10 year storm event reducing peak instantaneous flow to 17.4 mgd. The peak hour flow of 14.5 mgd was used as the maximum design basis of the SOIA treatment facilities, in accordance with Nebraska Title 123 for grit removal and primary clarification. The facilities will still have the ability to pass the peak instantaneous flow. This change does not impact the level of control that the LTCP identified. 3. LTCP identified having grit removal in the SOIA Lift Station. A decision was made to move this process to the MRWWTP to minimize impacts to the community surrounding the lift station. A building has been added to the MRWWP Improvements Project to accommodate the grit removal. 4. LTCP outlined an upgrade of the Transfer Lift Station to reliably pump a flow of 64 mgd to secondary treatment. It has been determined that 68 mgd is required to also account for recycle flows within the plant. To provide reliable pumping, the LTCP called for adding a new pump and rebuilding three of the existing four pumps. It has been determined that in addition to adding the new pump, all four existing pumps will be replaced because they are nearing the end of their service lives. 5. LTCP indentified the addition of an emergency power generation system at the Transfer Lift Station for backup power. This independent backup power is not required because the MRWWTP is fed from two independent power stations, which provides adequate backup power to the plant facilities. 6. Impacts from the flood may affect the City’s ability to deliver all of the MRWWTP Improvements on schedule. The City continues to monitor the situation to identify and mitigate potential impacts. At a minimum, portions of the design will be reevaluated to assure meeting existing and future permit requirements in the event of elevated river flows.

Changes from the LTCP The following describes the changes to in the Martha Street Sewer Separation Phase 1 project:
• During preliminary field investigations within the Lauritzen Gardens (Gardens) it was determined that additional investigation would be required involving identification of the limits of the balefill and additional geotechnical investigation within the Gardens. Design of the new sewer system was put on hold pending completion of the additional investigation. In order to meet the LTCP schedule and work around construction coordination issues with the Gardens, the project was split into 3 separate design and bid packages between the residential area of the project, located west of the Gardens, and the Gardens area. The three contracts are as follows: o Martha Street Area – Residential Combined Sewer Separation o Lauritzen Gardens Sanitary and Storm Sewer Separation o Lauritzen Gardens Storm Sewer Grading and Pipe System Abandonment
• The interconnectivity between the two areas did not allow completion of the 95% design of the residential area until pipe alignments were set in the Gardens area. This has resulted in a delay in the overall design schedule. Construction will still be started and completed per the original LTCP schedule. The LTCP identifies the following schedule for the bidding and construction of the Martha Street Sewer Separation project: Project Phase LTCP Anticipated Completion Date Scheduled Completion Date Final Design 10/7/2011 11/30/2011 – Residential (OPW 51880)

• The original concept, as described in the LTCP, was to separate the sanitary sewage from the existing combined sewer system within the Martha Street basin. The combined sewer within the limits of the Lauritzen Gardens was to be converted to a storm sewer pipe. The sanitary only sewer within the Gardens would remain. Field investigations found the pipe system under the balefill in poor condition. Rehabilitation or reconstruction of the existing pipes is not considered feasible. Construction of new sanitary and storm sewer systems and abandonment of the existing sewer infrastructure through the Gardens should prevent leachate from entering the storm sewer system. • The LTCP also states that the Martha Street flows will be routed north to the proposed Leavenworth Lift Station. A change was made to route the Martha Street flows south to the Riverview Lift Station. Initially, the dry weather sanitary sewer flow from the Martha Street basin will be directed to the Spring Street Lift Station until reconstruction of the Riverview Lift Station is complete. Then Spring Street Lift Station will be abandoned. The first segment is identified as Phase I. Phase II will be constructed to coincide with the reconstruction of the Riverview Lift Station. The Spring Street Lift Station will be abandoned upon completion of Phase II. The alignment change was the result of conflicts with the original planned route and the excessive depths of the gravity sewer extending north to the Leavenworth Lift Station that resulted in the Leavenworth Lift Station to be constructed deep into rock.

Project Information LTCP CSO Control Project Name: OPW 52004 Minne Lusa Stormwater Conveyance Sewer and Detention Basin Improvements Project
LTCP Project Description: Refer to the LTCP for more detailed information. A brief summary of the project is as follows: This project is located in the central portion of the Minne Lusa Basin and provides conveyance capacity for separated stormwater from sewer separation projects within the Minne Lusa (ML) Basin. The ML Stormwater Conveyance Sewer will consist of approximately 6,200 feet of 13 to 14 foot diameter tunnel. The sewer will convey separated stormwater from completed and future sewer separation projects in the ML Basin to the Missouri River. The stormwater conveyance sewer will have the capacity to convey up to a 10 year, 24 hour storm event from the separated areas of the basin. It is expected that the invert of the conveyance sewer will range from approximately 25 to 65 feet below the ground surface, and that a soft ground tunnel boring machine will be used for construction. The conveyance sewer alignment will commence at the southwest corner of the Storz West Detention Basin, extend west southwest along the Storz Expressway and then turn south upon crossing the North Freeway. The upstream end of the conveyance sewer will consist of a hydraulic drop structure positioned just east of Paxton Boulevard and N. 31st Avenue intersection. Two main branch conveyance sewers will discharge into the sewer tunnel at this location: one extending west along Paxton Boulevard to Fontenelle Park, and one extends south along John Creighton Boulevard to the Adams Park area. The branch sewers will tie into existing separated areas in the system and additional capacity will be provided for flows from future separated areas.
The ML Stormwater Conveyance Sewer will discharge into the existing Pershing and Storz Detention Basins, which will include a large concrete forebay to prevent scour and erosion as well as water quality including grit and floatables controls. Additional modifications to the Storz West and Pershing Detention Basin are necessary to accommodate the anticipated large volume of stormwater flows. These modifications will include existing embankment height modifications as well as additional embankments around the Pershing detention basin to maximize storage for the increased flows. Water quality, gravity flow conveyance, and aesthetics have been integrated into the modified detention basins design since all stormwater flows will discharge by gravity through the Storz West basin and to the north into the Pershing basin and finally out to the Missouri River. The other major design features include updated rugby fields, low flow channels and bioswales and water quality wetlands in the Pershing basin. The Pershing basin outfall modifications include an additional 72 inch outlet pipe and a modified CSO 105 discharge structure and channel modifications.

• Submitted the Tunnel Conceptual Design Deliverables (10%) and conducted a workshop in August 2011.
• Submitted the Detention Basins Conceptual Design Deliverables (10%) and held workshop in August 2011.
• Completed draft Geotechnical Interpretive Report for the tunnel alignment in September 2011. Anticipated Project Activity for Next Period • The design team (URS) is currently working on the preliminary design documents (30%) for the tunnel and detention basins with anticipated draft 30% design documents submitted in November 2011 and final 30% design documents completed in December 2011.
• The final design is anticipated to start in January 2011 for both the detention basins and tunnel and will be completed in December 2012. Changes from the LTCP During this period, no significant changes have been made to the overall project schedule from the project schedule in the LTCP. The following changes from the LTCP have occurred for this project:
• The construction schedule for the detention basins is anticipated to last approximately 18 to 20 months versus the LTCP construction schedule for the basins which were approximately 12 months for construction. The reason for the additional time is based on the complexity of the construction work in the detentions basins which is significantly different than the planned changes set forth in the LTCP. The entire Storz West basin and Pershing basin have to be re graded to drain all flows to the north and additional aesthetic and water quality features including rugby fields and wetlands are planned as part of the final design which were not considered in

the LTCP. The storage volume for the basins is significant and the design must meet high hazard dam requirements with berms that are 13 to 14 feet high surrounding both basins and the LTCP did not consider total volume for storage and high hazard dam criteria.
• The decision to bid the detention basins and tunnel as one project versus two projects has not been determined yet, however; the design tasks for both projects are scheduled to be completed at the same time to facilitate bidding the projects together if needed.

Changes from the LTCP During this period, no changes have been made to the overall project schedule from the project schedule in the LTCP. The following changes from the LTCP have occurred for this project: 1. The new SIFM will consist of approximately: a. 4,491 FT of new 48 IN diameter pipe from the vicinity of the valve vault on the existing SIFM south to the new Leavenworth Lift Station. b. 17, 576 FT of new 64 IN diameter pipe from the new Leavenworth Lift Station to the new headworks at the MRWWTP. 2. The SIFM project has been broken into 4 projects: a. SIFM – South Segment b. SIFM – Central Segment c. SIFM – North Segment d. Martha to Riverview Lift Station Phase 1 e. Spring Street Lift Station Improvements 3. The alignment of the SIFM – North Segment originally was to follow the Union Pacific Railroad alignment east of the Heartland of America Park wall. Conflicits with discovered OPPD high voltage power lines required the alignment to be adjusted west, beneath Heartland of America Park. The current concept for the SIFM consists of a rock tunnel instead of a soft ground tunnel due to soil conditions in and beneath Heartland of America Park. 4. The final alignment of the new SIFM continues to parallel the existing SIFM however a portion of the new 64 IN SIFM will be constructed in a new berm on the east side of the existing Missouri River levee. The LTCP had identified an alignment adjacent to the west side of the levee through railroad properties. 5. The Martha Street flows will be temporarily conveyed to the Spring Street Lift Station (following completion of the Martha to Riverview Lift Station Phase 1 project). The flows will be conveyed to the new Riverview Lift Station once the Riverview Lift Station Replacement and Martha to Riverview Lift Station Phase 2 projects are completed. Originally this flow was to go north to the Leavenworth Lift Station. 6. The alignment of the SIFM – Central Segment continues to be adjusted to accommodate property owner development of railroad spurs and relocation of an existing MUD water line. Other Items of Interest • The SIFM project has been impacted by the Missouri River flooding this summer in the following ways.

• Geotechnical Field Investigations. The high river levels have prohibited field work within the levee critical zone along the Missouri River. This has prevented the SIFM project from obtaining necessary geotechnical field sampling for the project.
• Field Locates of Existing Critical Utilities. The high river levels have prohibited field work within the levee critical zone along the Missouri River. This has prevented the SIFM project from obtaining necessary field locations on existing critical utilities.
• Restrictions on the Availability of US Army Corps of Engineers (USACE) Staff to Discuss SIFM Design Issues. The high river levels and attendant urgent demands on USACE staff to respond on levee and river issues has resulted in their not being available to the SIFM project team for design discussions and validations.
• Consequential Delays due to Required Design Revisions. As discussed above, the SIFM project team is continuing the design based upon current data and our best assumptions. However, this work could be overturned by future field information or comments that require redesign of the project.
• Difficulties in Accessing the Project Site. The emergency operations on the levee have made access to the project site problematic. Even with all of these impacts, the project is expected to meet the operationally complete date in the LTCP of May 2015.

Changes from the LTCP There was change in scope of the sewer separation from that envisioned in the LTCP due to several factors. Two areas of storm sewer system construction were removed from the contract due to field conditions encountered that eliminated the need for the storm sewer systems. A sewer line extension to Darling Inedibles (area 1) was eliminated due to changes in the internal business process flow connections. Storm sewer installations near Omaha Cold Storage (area 5) were also eliminated through a Change Order due to the discovery of a separated system on the business site. These two changes reduced the project cost by approximately $477,000. Other Items of Interest None

Project Activities and Progress The following is a brief synopsis of project activities and progress that has taken place during this period:
• Submitted 90% Deliverable to City and Utilities December 2010
• Conducted 90% Review Meeting and Utility Meeting December 2010
• Completed Final Plans and Specifications June 2011
• Completed Bidding July 2011
• Commenced construction on Contract 2 on August 31, 2011.
• Notice to Proceed for Contract 1 issued on October 3, 2011.
Anticipated Project Activity for Next Period • Continue Construction Phase Activities Changes from the LTCP The following changes from the LTCP have occurred for this project:
• The Ohern/Monroe Industrial Area Lift Station, Force Main, and Gravity Sewer project (LTCP Project 1A) is being bid in two separate packages due to the differences in the type of construction: o OPW 51596 Contract 1 South Omaha Industrial Area Lift Station Bid Package. o OPW 51597 Contract 2 South Omaha Industrial Area Force Main and Gravity Sewer.
• The City’s original schedule for the LTCP required completion of the Final Design for the project by May 31, 2010. The intent was to fast track this project because of its significant water quality benefit to the Missouri River. However, it was noted that the original construction schedule would result in completion of the conveyance system (lift station, force main, and gravity sewer) to the MRWWTP significantly in advance of the plant being capable of handling the industrial waste. The schedule was modified to make it consistent with the schedule for upgrades at the MRWWTP. Thus, Final Design was completed in 2011. • The design storm was revised following additional analysis. The design storm stated in the LTCP for this facility and pipeline sizing was the 25 year, 24 hour which was changed to a 10–year, 24 hour. This resulted in sizing of facilities and pipelines that are consistent with City standard for design flows at stormwater influenced facilities and do not affect the overall level of control. This decreases the facility conveyance design flows slightly from 18.3 MGD (25 year, 24 hour storm based) to 17.4 MGD (10 year, 24 hour storm based), but still ensures that the industrial waste will be conveyed to the MRWWTP for full treatment. This
SOIA_ANNUAL_PROJECT_PROGRESS_REPORT_30SEPT2011.DOCX 2 CITY OF OMAHA COMBINED SEWER OVERFLOWS NPDES PERMIT NO. NE0133680 ANNUAL REPORT OCTOBER 1, 2010 THROUGH SEPTEMBER 30, 2011
modification does not result in a change of the level of control as described in the LTCP. • Relocate grit removal pretreatment to the MRWWTP industrial treatment facilities. This change was made because of the odor associated with pretreatment of this waste. It was determined that it would be easier and more acceptable to the public for operations and maintenance to handle these materials directly at the MRWWTP. This change will reduce the footprint of the facility and extent of solids handling maintenance required to handle odorous materials in commercial/residential areas. • Provide for ability to expand the industrial lift station to include wet weather equalization and grit removal in the future. Equalization at the lift station would be added if flow rates increase due to increased industrial flows, unexpected levels of wet weather infiltration, or if it is determined that equalization of peak flows will improve performance of the industrial treatment system. Grit removal would be installed to reduce the buildup of solids in the equalization tank and/or in the event that solids are determined to be a problem in the wet well, pumps, or pipeline elements downstream.

Project Activities and Progress The following is a brief synopsis of project activities and progress that has taken place during this period:
• Preliminary Design (30% Design), Basis of Design Report, completed January 2011
• Wetlands delineation and final report completed July of 2011.
• Geotechnical Investigations in support of detention basin design were completed in September 2011.
• Design Development (60% Design) plans, completed August 2011.
• Preliminary Drainage Report, completed August 2011. Anticipated Project Activity for Next Period • Prepare Construction Documentation (95% Design) plans and specifications.
• Finalize Agency Review plans and specifications (95% Design) in January 2012
• Finalize Construction Documentation (95% Design) plans and specifications in February 2012.
• Start preparation of Bidding/Contract Documents (100% Design) in March of 2012 Changes from the LTCP During this period, several minor changes have been made to the schedule for the Saddle Creek Separation Project from the schedule shown in the LTCP. These are shown in the table provided on the previous page of this report. These changes do not impact the completion of construction or operationally complete dates shown in the LTCP. The following changes from the LTCP have occurred for this project:
• The sub basin area to be separated was listed in the LTCP at 381 acres. This area was based upon the drainage area of the unnamed creek that flows through West Lawn Cemetery. As part of the concept design for the project it was recommended that the pipeline be sized to handle flow from previously separated areas north of Center Street at 55th and 58th Street as well as separation of flows for the area south of Arbor Street and west of Westbrook Avenue. Accounting for these additional areas the project design now will accommodate separated storm flows from 777 acres. The project is incorporating the necessary infrastructure to connect the separated flows along Westbrook Avenue into the new storm sewer. However, the final connections to the new pipeline for the previously separated flows north of Center Street are not included as part of this project. The additional sewer separation will result in a reduced size of the RTB.
• The pipe size identified in the LTCP indicated that the proposed storm sewer would range from 34 inches to 78 inches in diameter. The current pipe size ranges from 24 inches in diameter pipe at the control structure for the detention basin to 96 inches in diameter for the pipeline between the existing 7 foot by 7 foot box and the new open channel near 62nd Street. From 64th Street, west to the outlet into Little Papillion

Creek the storm water flows will be conveyed in a twin 8x7 box culvert. The increase in pipe size is required to account for the additional flows from the separated areas north of Center Street at 55th and 58th Street as well as the separated flows south of Arbor Street and West of Westbrook Avenue.
• The project contains two green solutions. The first green solution includes detention basins at Westlawn Cemetery that reduce the peak flow rates and thus the required pipe size. The detention basins are also being designed to provide water quality benefits for normal rainfall events. The second green solution is an open channel at the west end of the project between approximately 62nd and 64th Streets. Other Items of Interest The open channel green solution was awarded a grant through the Papio Missouri River NRD. A grant has been submitted to fund the detention basins green solution.

Project Information LTCP CSO Control Project Name: Saddle Creek Retention Treatment Basin (RTB)
LTCP Project Description: Refer to the LTCP for more detailed information. A brief summary of the project is as follows: The Saddle Creek RTB will treat the combined sewage conveyed to CSO 205 – 64th and Dupont at a maximum treatment rate of approximately 315 mgd. As currently envisioned, the system will consist of coarse screening, grit removal, a compartmental basin with a combined volume of 6.6 MG (equal to 30 minutes of detention time at peak flows), sodium hypochlorite disinfection/dechlorination, and possible effluent pumping to Little Papillion Creek. Combined sewage remaining in the compartments will be pumped after a storm event to the CSS for treatment at the Papillion Creek Wastewater Treatment Plant (PCWWTP). It is anticipated that the RTB will be dewatered over a maximum period of 24 hours at an approximate flow rate of 6.6 mgd. The dewatered flows will receive full secondary treatment at the PCWWTP.

Changes from the LTCP During this period, no changes have been made to the overall project schedule from the project schedule in the LTCP. The following changes from the LTCP have occurred for this project:
• The scope of the project was changed from the LTCP. The original scope was for the construction of a new sanitary sewer from Spring Street to the Grover Street Outfall Sewer and the abandonment of the Spring Street Lift Station. The preliminary design of the system found a single segment of sanitary sewer could be installed to separate the sanitary sewer flow from the storm sewer system. The Spring Street Lift Station will remain in service on a temporary basis. (See the Martha St Sewer Separation description for more details). All connections between the sanitary and storm sewers were removed. The change resulted in a substantial construction cost savings. The new sanitary sewer from Spring Street to the Grover Street outfall would have been installed at minimum grade which could have created operational problems for the City.
• The existing storm sewer outfall was found to be in usable condition after being cleaned by City forces. Work was included in the project documents for the installation of a headwall for the pipe and the installation of a flap gate. The headwall reconstruction work is outside of the scope of the LTCP and was included as a separate bid schedule.

Project Activities and Progress The following is a brief synopsis of project activities and progress that has taken place during this period:
• Conceptual (10% design) Basis of Design Report completed August 2011.
• Green Solutions (10% design) Basis of Design Report completed August 2011.
• Submittal of Field Data completed September 2011. Anticipated Project Activity for Next Period • Final submittal of Basis of Design Report and Green Solutions Report following revisions from QRF review. Changes from the LTCP The LTCP only identified the scope of work in the Webster/Nicholas separation area east of 27th Street to include sanitary sewers and storm sewers. The conceptual design varies from the LTCP in the following:
• The conceptual design recommends an interconnection between the existing combined sewers on Burt Street and the west end of the Webster Street storm sewer located on Cuming Street to better utilize capacity of the Webster Street storm sewer and reduce street flooding along Burt Street adjacent to Creighton University. This project may be interim in nature until the Webster Street storm sewer is extended to the west. Although this project provides a benefit, it is not considered separation as the Webster Street storm sewer is considered part of the combined sewer system.
• The conceptual design identified several other storm sewer projects in the southern part of the study area to route inlets to the Webster Street storm sewer. These projects would reduce the flow on the existing combined sewer system and increase the flow on the Webster Street storm sewer. The Webster Street storm sewer is part of the combined sewer system and these projects are not considered separation. Because the projects are not considered separation the conceptual design report lists the project as low priority projects that are not likely to be implemented.
Other Items of Interest • The conceptual design recommends a series of sanitary sewer projects to connect separate sanitary sewers in the study area to the existing Webster Street sanitary sewer or an extension of the Nicholas Street storm sewer. The conceptual design incorporates an alignment alternative from the Lamp, Rynearson & Associates Inc. evaluation of alternatives for extension of the Nicholas Street storm sewer. Alignment Alternative B extends through the Webster Nicholas separation area and provides for approximately 6 separation points.

• The conceptual Basis of Design Report sets forth three storm sewer projects in the northern part of the Webster Nicholas area. These projects involve separate storm sewers that would connect to an extension of the Nicholas Street storm sewer. The City of Omaha will need to determine how much capacity in the Nicholas Street storm sewers can be committed to separation in the Webster Nicholas separation area. A determination of projects to implement will need to await additional evaluation of the extension of the Nicholas Street storm and sanitary sewer projects.

Project Information LTCP CSO Control Project Name: Webster Street – Phase 2
LTCP Project Description: Refer to the LTCP for more detailed information. A brief summary of the project is as follows: The Webster Street Phase 2 project included extension of a 96” combined trunk sewer and two sanitary sewers varying from 15” – 18”. The project extended a trunk sewer originally built in 2001 as part of the construction of CenturyLink Center. The Webster Street – Phase project extended the sewers from 20th and Cuming Street to approximately 27th and Cuming Street. The trunk sewer is designed to provide additional capacity for the Burt Izard basin. The separate sanitary sewer was used to separate local sanitary sewers and to provide opportunity for future sanitary sewer separation in the future.

Change Effects: (Check all that apply) Scope Schedule Cost Brief Summary from Change Description and Justification TM
SCOPE – During construction it was discovered that the existing pavement subgrade was inadequate to support construction activity and the entire street width needed to be replaced. SCHEDULE - LTCP Schedule identified a Construction start date of January 27, 2010 and a Construction Completion date of October 18, 2011. MUD relocation of utilities was to be completed by Spring 2010 per the MUD schedule included in the Construction Documents. Due to severe winter conditions, MUD notified City at the Pre-construction conference on March 22, 2010 that relocations would not be completed to allow the Contractor to start until May 3, 2010. COST – Additional street replacement and associated costs result in increased overall cost of the project. Change orders totaling approximately $1,040,000 will increase the construction cost to approximately $2,885,000, as compared to the LTCP budgeted cost of $2,819,000 or an overage of approximately $66,000.

Change Description and Justification TM 24th & Ogden Sewer Separation Project Introduction The purpose of this TM is to summarize a request for change to scope, schedule, and costs. This change was initiated by the PMT based on the change of schedule for start of construction. This is not a Force Majeure change. Approval is being requested for these changes. This change also documents the change in scope due to additional street replacement required. This change also documents the change in construction costs associated with the scope of work change. Description of the Change SCOPE - During construction it was discovered that the existing street subgrade was inadequate to support the construction activity associated with the separation project. The street pavement that was to remain in place was damaged due to inadequate subgrade support. The decision was made by the City to replace the entire street width on portions of the project, resulting in additional bid items and adjustment of existing bid quantities. However, even with this additional work the overall completion of the project was not affected. SCHEDULE - The LTCP schedule identifies the following schedule for the bidding and construction of 24th & Ogden Sewer Separation Project: LTCP Scheduled Completion Actual Completion
Bidding 01/26/2010 Council Award 12/08/2009
Construction Start 01/27/2010 Notice to Proceed 5/12/2010
Complete Construction 10/18/2011 Notice of Substantial Completion 12/23/2010
Bidding and award of the project was completed ahead of the LTCP date. The project included extensive utility relocations of gas and water utilities by MUD. The Contract Documents included the MUD developed schedule that identified completion of the utility relocations by Spring 2010 to allow the Contractor to start construction. The City scheduled and conducted a project pre-construction conference on March 22, 2010 to discuss the start of construction with the utilities and the contractor. At that meeting MUD notified the attendees that MUD utility relocations were behind schedule due to the severe winter weather slowing the relocation work. MUD anticipated that with additional MUD crews
OMAHA CSO CONTROL PROGRAM 3
assigned to the project, MUD would complete the portion of the work by May 3, 2010 that would allow the Contractor to start work in the 24th Street corridor and that MUD could then complete the remainder of the work ahead of the Contractor’s operations. Notice to proceed was issued on May 12, 2010. However, even with delay in Notice to Proceed, construction was completed ahead of the LTCP completion date on December 23, 2010. COST – The change in scope for street replacement resulted in additional bid items and additional bid quantities. Change orders were processed as a result of these scope changes increasing the construction cost over the contract bid amount. The LTCP Base Construction Budget (including budget uncertainty) was $2,819,000. The anticipated final cost of the construction after change orders is approximately $2,885,000, approximately $66,000 above the LTCP budgeted cost. Impacts of the Change SCOPE – The change in scope of the pavement replacement quantities resulted in additional costs above the contractor bid amount. SCHEDULE - While the start of construction was delayed due to the MUD utility relocation delay, the LTCP construction schedule included sufficient contingency in the construction schedule to accommodate the delay of the start of construction as well as the additional work associated with the addition paving. COST – While the change in scope of the street replacement resulted in additional costs above the contract bid amount, the resulting overall project construction cost was only slightly above the project LTCP Base Construction Cost (which included budget uncertainty).

C. Shoring plans and certifications if needed
D. Dewatering plans. – George Hunt, representing Pat Nelson asked how the pumped water will be handled. The answer: if there are no signs of contamination such as raw sewage from broken sewer services, or washed hydrocarbons, then the fluid from the dewatering application will be diverted to the storm system (if it is already in place). Otherwise it will be diverted to the sanitary (or combined) sewer system. See “O” below.
E. Removing trees. – There is no need for a migratory bird study before removing trees in the project area, since it is not a grassland, wetland, stream, woodland habitat or part of a bridge. However, it is a good practice to watch whether there are nesting activities on the trees before taking them down. See note below.

H. The City is also required to conduct onsite interviews with a representative group of covered workers about two weeks prior to project completion. The Contractor/Sub-contractor must allow these interviews
I. The Contractor is required to post at the construction site, Davis Bacon Act information and the specific wage rates for the project construction (the wages may be different for each of the three separation projects depending on wage updates and when the projects were bid). Davis Bacon wage rate information needs to be posted daily at the job site and is subject to inspection at any time by NDEQ, OIG, or other federal agencies without advance notice.
7 of 10 PRE-CONSTRUCTION CONFERENCE PROJECT: OPW51497, 24TH & Ogden, Sewer Separation Project March 22, 2010 1:00 P.M. OPW 6TH Floor – North Conference Room
J. The Contractor is required to be bound by the Equal Employment Opportunity (EEO) requirements of EPA regulations and to post EEO information at the project construction site. EEO signs and information needs to be posted daily at the job site and is subject to inspection at any time by NDEQ, OIG, or other federal agencies without notice.
K. The Contractor shall have a designated EEO person who is responsible for monitoring and ensuring the company EEO policy is being carried out, reported, and documented.
L. The City has the responsibility to assure compliance with EPA specified MBE/WBE/DBE Sub-contracting goals. At this pre-construction meeting we ensured that the Contractor listed Sub-contractors, which are doing the work that was indicated in the bid submittal on forms 6100-3 and 6100-4.
M. As part of the ARRA/stimulus funding, the Office of Inspector General (OIG) will conduct unannounced site visits. Items they will inspect include compliance with Davis Bacon Act wage rates, Buy American provisions, record keeping, etc.
N. As part of the SRF loan funding, the Nebraska Department of Environmental Quality (NDEQ) will conduct site visits (usually announced but may be unannounced). Items they will inspect include compliance with ARRA and SRF loan requirements, NDEQ sign on site, general construction progress in relation to schedule, etc.
O. Dewatering requires NDEQ - Construction Dewatering General Permit. The permit covers discharge of groundwater and stormwater from excavation sites into state waters and should be prepared and be held by the Contractor (Please disregard the dewatering comment made during the meeting)

Project Substantial 12/17/2010 10/13/2010 Completion Bidding and award of the project was completed ahead of the LTCP date. Construction Notice to Proceed was delayed due to complications with property acquisition, design revisions necessary due to coordination with Omaha Public Schools changes in design and the winter weather conditions. However, the actual Notice of Substantial Completion of construction meet the LTCP completion date identified.
Justification The bidding for the project was completed ahead of schedule as shown in the above table. The project included coordination with the Omaha Public Schools in site development for a new school. Additional traffic control requirements by the City of Omaha necessitated revisions to the plans for street widening and re-alignment of the storm sewers after the initial 90% drawings were completed. Property acquisition complications also developed resulting in condemnation proceedings being required. The City scheduled and conducted a project pre-construction conference on April 22, 2010 to discuss the start of construction with the utilities and the contractor. Notice to Proceed to the Contractor was issued on May 13, 2010.
OMAHA CSO CONTROL PROGRAM 2
Actual substantial completion was issued on October 13, 2010. The LTCP completion date was December 17, 2010. Even with the delay in the start of construction, the construction was completed ahead of the LTCP schedule completion date.
Impacts of the Change While the start of construction was delayed due to property acquisition issues, the LTCP construction schedule included sufficient contingency in the construction schedule to accommodate the delay. There are no cost impacts to the Program as a result of this change. There are no scope impacts to the Program as a result of this change.

Scope Schedule Cost Brief Summary from Change Description and Justification TM
The LTCP schedule identified a construction completion date (end of Task 7) for the Aksarben Village Phase A project as May 3, 2013. The Aksarben Village Neighborhood Sewer Separation project that was bid on July 13, 2011 has a completion date identified as September 1, 2013. The project completion date was determined by the Project Team. Factors that affected the completion date included; • timing of the bid opening, which reduced the amount of sewer work that could be completed in 2011, • physical constraints, which limits the number of crews that can work at one time, and • a larger scope of work (more pipe replacement) than was originally anticipated.
These factors are described in more detail in the attached Justification Technical Memorandum. Efforts will be made during construction to still meet the LTCP project completion date of May 3, 2013.
The Aksarben Village Sewer Separation project that was bid on July 13, 2011 also included substantial portions of the LTCP Project Aksarben Village Phase B project (for sewer rehabilitation to reduce inflow and infiltration to the separated sewer system). The LTCP identified a construction completion date for Aksarben Village Phase B of July 28, 2017. The goals of the LTCP Phases A and B are anticipated to be met through the current construction project, based on the results of field investigations, after construction is complete. Additional rehabilitation in the Aksarben Village Neighborhood sewer separation project area would be associated with optimizing the size of the RTB under the Saddle Creek Retention Treatment Basin (RTB) project.

TECHNICAL MEMORANDUM
Change Description and Justification TM OPW 51151 - Aksarben Village Neighborhood Sewer Separation Phases A and B. Introduction The purpose of this technical memorandum (TM) is to document a change to scope, schedule, and/or costs. This change description and justification was prepared by the PMT to document the reasons that the proposed project completion date for the Aksarben Village Neighborhood Sewer Separation Phase A project is after the Omaha CSO Program Long Term Control Plan (LTCP) scheduled project completion date. Description of Change The LTCP schedule identifies the following schedule for project completion.
LTCP Scheduled Construction Completion Date Contract Completion Date Aksarben Village 05/3/2013 9/1/2013 Neighborhood Sewer Separation Project Completion – Phase A
Aksarben Village 7/28/2017 9/1/2013 Neighborhood Sewer Separation Project Completion – Phase B
Justification The LTCP schedule identified two projects for the Aksarben area. The construction completion date for the Aksarben Village Neighborhood Sewer Separation Phase A project per the LTCP is May 3, 2013. The construction completion date for Aksarben Village Neighborhood Sewer Separation Phase B per the LTCP is July 28, 2017. The Aksarben Village Neighborhood Sewer Separation Phases A and B, is a combination of both of these projects and was bid on July 13, 2011. The estimated construction completion date is September 1, 2013, which is later than the LTCP completion for the Phase A project of May 3, 2013, but prior to Phase B project of July 28, 2017.

CSO! Program Office: Central Park Plaza, 222 S. 15TH St., Suite 1406S, Omaha, NE 68102 (402) 341-0235 • [email protected] • www.omahacso.com The anticipated project construction completion date was developed by the Project Team, Veenstra & Kimm. The assumptions and justification used by the Project Team in determining the anticipated project construction completion date are detailed in the attached document “OPW 51151 Aksarben Village Sewer Separation Determination of Contract Period”. Factors that contributed to the delay in the completion date included timing of the bid opening, physical constraints of construction crews, and an increase in the overall scope of work due to the combination of the two phases to realize design and construction efficiencies. Delayed Completion Date As described in the attached June 21, 2011 letter to Donna Garden with the Nebraska Department of Environmental Quality (NDEQ), the start for the final design of the project was delayed for several reasons; however, the LTCP start of construction date of September 26, 2011 is still expected to be met. Due to the start of construction in the fall and unpredictable winter weather concerns, a decision was made by the City Construction Division to confine the work area in 2011 to the Elmwood Park area and not start sewer construction work in the street right-of-way in 2011 to keep roads from being closed (inconveniencing residents in the neighborhood) over a winter shut-down period. The timing of a fall start date affected how much work could be completed in 2011 and affected the project completion date. In addition, the Elmwood Park diversion work was not included in the LTCP, as it is a Green Solution that was proposed by the Project Team during design. Therefore, the additional time needed to construct the Elmwood Park diversion facilities (which includes replacing approximately 220 feet of failed stormwater pipe beyond the needs of the Green Solution itself) was not included in the LTCP schedule. Physical Constraints Two construction crews were assumed in the development of the estimated project construction completion date prepared by the Project Team. The City considered accelerating the construction schedule with the use of three construction crews. It was determined that three construction crews could complete the project in a shorter time-frame; however, due to the utility companies concurrently performing their relocation work, the physical constraints of the fully developed residential neighborhood, and the ability to keep enough streets open for traffic flow, it was determined that using three working crews was not feasible. Increase in Scope of Work During the design of the Aksarben Village Neighborhood Sewer Separation project, the project scope increased over the original LTCP Aksarben Village Phase A scope to accomplish the project’s objective. Increases in scope included an increased length of storm and sanitary sewer by 45 percent over the estimated pipe length in the LTCP for Phase A, addition of a Green Solution in Elmwood Park, and addition of sewer rehabilitation originally planned for a separate Aksarben Village Phase B project. A summary of the additional work is included in the table below.

Project Item Proposed in LTCP Actual Proposed Storm Sewers 12,300 feet of new storm 17,897 feet of new storm sewer from sewer pipe from 15” – 12” – 84” diameter 84” diameter
Sanitary Sewers None 870 feet of replacement sanitary sewer
Elmwood Diversion Not in LTCP 1,023 LF of new storm sewer, 3 Green Solution bioretention gardens, 2 stormwater detention cells
Sewer Rehabilitation Was planned for Phase B Includes installation of external frame of LTCP seals, chimney seals, and solid manhole covers.
Costs Phase A – $5,349,000 Engineer’s Estimate - $9,202,820 plus Budget uncertainty Low Bid - $8,078,653 of $230,000 Phase B - $3,678,000 plus Budget uncertainty of $158,000 Total of $9,415,000
The attached letter to the NDEQ dated June 21, 2011, states that the additional work would not affect the project completion date; however, upon further review by the Project Team, this work is estimated to have an effect on the overall completion date as described above. The inclusion of the Phase B work into the current project accomplishes the objectives of both Phase A and Phase B projects. Impacts of Change While the LTCP project completion date for Phase A is later than the LTCP date, the Aksarben Village Neighborhood Sewer Separation project achieves the goals of both the Phase A and B projects, and will meet the LTCP date for Phase B of July 28, 2017 while staying below the LTCP combined budgets for Phases A and B and providing additional community and water quality benefits to the community. Any future rehabilitation of manholes in the Aksarben Village Neighborhood Sewer Separation project area would be associated with the sizing of the RTB under the Saddle Creek Retention Treatment Basin (RTB) project. Efforts will be made to still complete the Aksarben Village Neighborhood Sewer Separation project construction prior to the Phase A date in the Construction Contract of September 1, 2013. The delay in the Aksarben Village Phase A schedule will not affect any LTCP milestone dates in the City’s CSO Permit. - 3 - ______

MEMORANDUM OMAHA CSO CONTROL PROGRAM
OPW 51151 AKSARBEN VILLAGE SEWER SEPARATION Determination of Contract Period
TO: Ned Tramp Mike McIntosh Emily Holtzclaw
FROM: Bob Veenstra Jr.
DATE: July 5, 2011
This memorandum is to set forth information on Veenstra & Kimm, Inc.’s determination of the contract period necessary for construction of the Aksarben Village Neighborhood Sewer Separation project. The contract period will be calculated based on the total number of calendar days from the start of construction to the completion of construction.
The analysis by Veenstra & Kimm, Inc. was based on the progression of construction of the project and a determination when the overall contract would be completed. Based on the calculated completion date the number of calendar days can be established.
The following assumptions were used in developing the estimated contract period.
1. Pipe laying on large pipe would average 60 feet per day.
2. Pipe laying on smaller diameter pipe would average 120 feet to 150 feet per day depending on depth.
3. Approximately 1/2 day was added to the schedule for each day a manhole or other similar structure would need to be constructed.
4. Paving and restoration would follow 30 to 60 days after completion of pipe laying.
5. Except for the work on the Elmwood Diversion, there would be two pipe laying crews.
6. The normal winter shutdown would be from November 30 through March 15.
DETERMINATION OF CONTRACT PERIOD 1 OMAHA CSO CONTROL PROGRAM
In developing the projected contract period, three other factors were taken into consideration. These factors are:
• The project includes the replacement of an existing combined sewer on Pine Street with a smaller pipe. The smaller pipe is necessary to allow the new storm sewer to cross the combined sewer system. The crossing is required to connect the new storm sewer that starts at 63rd and Shirley to the existing storm sewer on Pine Street. The new storm sewer starting at its outlet at 63rd and Shirley is located on the west and north side of the large diameter combined sewer. In the vicinity of 61st and Pine it is necessary for the storm sewer to cross to the east and south side of the combined sewer to connect to the storm sewer. The crossing can only be accomplished by decreasing the size of the combined sewer to provide vertical separation.
To decrease the size of the combined sewer on Pine Street it is necessary for the upstream separation to be completed before the work on Pine Street to reduce the combined sewer. The work on Pine Street will need to be scheduled at the end of construction after the upstream separation has been completed.
• The staging plan was developed for two construction crews working in areas that would allow for a logical progression of construction. This logical progression is designed to minimize the disruption to the neighborhood by avoiding large concentrations of construction in an area that would make access extremely difficult.
Veenstra & Kimm, Inc. recognizes the project is of a nature that would allow for more than two construction crews. However, the introduction of more than two crews for other than a short term basis will result in a significant disruption to the neighborhood. While the City may choose to approve more than two construction crews to work in selected areas, it did not appear prudent to base the schedule in a manner that would mandate three or more construction crews in the relatively small neighborhood.
• The construction schedule was developed recognizing the Elmwood Diversion would need to be constructed and the area stabilized prior to the construction of storm sewer upstream that would result in discharges of stormwater through the Elmwood Diversion. If stormwater is discharged to the Elmwood Diversion prior to the area being fully vegetated significant erosion and damage to the Elmwood Diversion could be experienced.
Based on information provided by the City it appears construction of the project will not start until late September.
The pipe laying activities on the project must start with the development of the 63rd Street Outlet Storm Sewer from Shirley northerly. The work on 63rd Street requires construction of the large diameter storm sewer and complete replacement of the street. Given the amount of work to be completed on 63rd Street it does not appear reasonable to assume the contractor could start pipe laying on 63rd Street and complete the restoration before the onset of winter conditions.
Based on the start date in late September, pipe laying activities on 63rd Street and Shirley would not start until the spring of 2012. Pipe laying activities upstream of the Elmwood Diversion could not start until at least the spring of 2012. The project schedule was based on the assumption pipe laying would start in the early spring of 2012.
DETERMINATION OF CONTRACT PERIOD 2 OMAHA CSO CONTROL PROGRAM
In developing the construction schedule it is assumed work on the Elmwood Diversion could start immediately following notice to proceed in late September. The contractor should construct the Elmwood Diversion through the fall and winter months. Construction of the weirs and other concrete facilities on the Elmwood Diversion can occur during the winter months. In developing the schedule it is assumed the Elmwood Diversion would be fully constructed in the fall and winter months. The contractor would be allowed to complete work on the Elmwood Diversion beyond the normal November 30 shut down date.
Constructing the Elmwood Diversion during the winter months is considered essential to the completion schedule of the project. Completing the Elmwood Diversion by the early spring of 2012 allows the planting in the Elmwood Diversion to occur in the early spring. This allows the area to be stabilized by the early to mid-summer. Pipe laying upstream from the Elmwood Diversion can start at that time. Because there is a reach of storm sewer from the Elmwood Diversion upstream to the first set of inlets the pipe laying upstream from the Elmwood Diversion can start several weeks before the area is fully stabilized. This allows for earlier start of pipe laying without impacting the Elmwood Diversion.
The schedule developed by Veenstra & Kimm, Inc. assumes by the early spring of 2012 the Elmwood Diversion would be completed and work would move forward on pipe laying with two pipe laying crews operating simultaneously. The focus of construction in 2012 would be the outlet storm sewers to 63rd and Shirley and the Elmwood Diversion. Construction in 2012 would include the areas upstream of Pine Street.
Attached is a spreadsheet showing the development of the construction contract period. The contract period is assumed to start around September 15, 2011. Based on this schedule the completion date of the project would be governed by the work on construction crew No. 2 working in the Pine Street area in the spring and summer of 2013. This crew would be scheduled to complete all work around September 1, 2013. The period from September 15, 2011 to September 1, 2013 would translate to the equivalent of a 720 calendar day construction contract period to substantial completion. Allowing 30 calendar days for final completion, the contract period would total 750 calendar days with a projected October 2013 final completion.
The construction period is divided into four periods. The first period would start with notice to proceed around September 15, 2011 and would continue through the end of the winter shutdown period on March 15, 2012. During this period of 182 calendar days the contractor would work on the Elmwood Diversion. No other work is shown in the fall months and the winter shutdown period.
The second period of construction would start on March 15, 2012 and would continue through the winter shutdown period on November 30, 2012. During this construction period it is assumed the contractor would have approximately 180 calendar days that could be devoted to pipe laying activities. At the end of the pipe laying activity would be an approximately a 45 to 60 day period for restoration. A factor of approximately 15 calendar days was built into the schedule to recognize weather will impact the construction progress.
The enclosed schedule shows each crew would have approximately 180 pipe laying days on their respective phases. One construction crew would work on the area extending upstream from 63rd and Shirley. The other crew would start at the Elmwood Diversion and continue upstream from that location.
DETERMINATION OF CONTRACT PERIOD 3 OMAHA CSO CONTROL PROGRAM
The enclosed spreadsheet indicates that pipe laying activities should be completed by approximately October 1, 2012. A 45 day restoration period is included in the schedule. Both crews are scheduled to complete restoration by November 15, 2012. The weather float is not included in the schedule and would allow approximately 15 days before the November 30th winter shutdown.
Period 3 of the construction contract would be the winter shutdown from November 30, 2012 through March 15, 2013. No work would be allowed during this period of approximately 109 calendar days.
The fourth period would start on March 15, 2013 and would extend through the completion of construction. Crew No. 1 would complete work on 57th and Walnut Street. This crew should be complete with pipe laying activities by May 31, 2013 and should be substantially complete by July 1, 2013.
Crew No. 2 would start with remaining work on Woolworth and then move to the remaining two phases on Pine Street. This crew should complete the primary separation work before May 31, 2013. Pipe laying activity in the Pine Street area would extend another two months until approximately August 1, 2013. This crew would have its substantial completion scheduled for September 1, 2013.
In developing the project schedule the goal was to complete the separation work by May 31, 2013. The only work that would remain after May 31, 2013 would be the work in the Pine Street area. As indicated earlier, work on the Pine Street area cannot be undertaken until the upstream separation has been completed. There is limited additional separation work in the Pine Street area. The primary focus of the Pine Street area would be to complete the connection of the existing storm sewer through the new storm sewer. This would be the last activity on the project and would occur after the replacement of the Pine Street combined sewer.

SCOPE - At the March 10, 2010 progress meeting, it was discussed that LRA needed to investigate the need for connection of the 30-inch sewer in 11th Street to the proposed Nicholas Street system. At the April 14, 2010 progress meeting, it was determined that the 30-inch combined sewer grade conflicts with the proposed grade of the new storm sewers. There is no acceptable alternative except to separate the 11th Street sewers north of Nicholas Street as part of the Nicholas Phase 1 project. Therefore, additional scope and fee is required for the Nicholas Phase 1 project to include the separation of the 11th Street Corridor north of Nicholas Street. In addition, a Phase 1 Environmental Site Assessment is needed on the Economy Products property prior to purchase by the City, and environmental subsurface investigations are required on some properties which will be accomplished in early 2011. SCHEDULE - Submittal of the 95% plans and specifications will be postponed for review until the environmental investigations are completed and the environmental requirements can be incorporated into the 95% plan submittal. COST – Additional costs associated with the additional sewer separation along 11th Street and the impacts of the environmental investigations impact the Project budget.

Change Description and Justification TM Nicholas St. Phase 1 - 10th to 16th Separation Project Introduction The purpose of this TM is to summarize a request for change to scope, schedule, and costs. This change was initiated by the Project Team based on the results of field investigations. This is not a Force Majeure change. Approval is being requested for this change in schedule. Description of the Change SCOPE - During field investigations, it was discovered that the existing 30-inch combined sewer in 11th Street conflicts with the proposed grade of the proposed 108-inch diameter storm sewers. Due to the flat grade of the 30-inch sewer and the fact that the grade of the 108-inch sewers cannot be adjusted, it was determined that the 11th Street sewer contributing area needs to be separated so that a new storm sewer in 11th Street can be connected to the new 108-inch storm sewer. A new sanitary sewer in 11th Street will connect to the proposed sanitary sewer constructed as part of the Nicholas Street Phase 1 project. A siphon under the proposed 108-inch storm sewer is not feasible due to the flat grade and there is no alternative alignment for the 30-inch combined sewer. SCHEDULE - During final design of the project it was determined that a Phase I Environmental Site Assessment will be required on the former Economy Products property prior to purchase by the City, and environmental subsurface investigations to characterize the chemical constituents in the soil and groundwater will be required due to the initial Environmental TM Assessment of the project area. The design of the project will be completed to the 95% level and placed on hold, pending completion of the Phase I Environmental Site Assessment and environmental investigations. The 95% documents will then be completed, incorporating environmental requirements, and submitted for 95% review and comment. There is sufficent time in 2011 to complete this work, right-of-way acquisition, and permitting prior to bidding per the LTCP schedule. The LTCP schedule identifies the following schedule for the bidding and construction of the Nicholas Street Phase 1 Project:

The Nicholas Street Phase 1 project is not a driver project for the LTCP Sewer Separation Phase 3 milestones. COST - Additional design and construction costs are anticipated due to the expansion of the project scope to include the 11th Street separation area. Work Change Authorizations have been prepared for this work. Impacts of the Change SCHEDULE - LRA does not anticipate a schedule impact to the construction schedule. The design of the additional sewer separation will not impact the schedule. SCOPE - The scope of the Nicholas Street Phase 1 project is increased due to the additional effort required for the field investigations and design work associated with the separation of the sewers in 11th Street. Additional topographic survey is required. Additional CCTV and geotechnical investigations are required. COSTS - Estimates for construction of the additional sewer separation facilities will be updated following completion of the environmental investigations and incorporation of additional requirements into the contract documents,if required. A 15% contingeny is being carried in the 95% cost estimate to account for these costs.

The Olsson Consultant Contract was approved by the City Council on February 23, 2010. The kick-off meeting with the Consultant was held on March 17, 2010. Justification The Consultant was not issued Notice to Proceed until February 23, 2010. The Consultant began work immediately and the kick-off meeting was held on March 17, 2010. The 30% preliminary design was submitted ahead of the LTCP schedule on November 19, 2010. The amendment for final design is currently being negotiated
OMAHA CSO CONTROL PROGRAM 2
Impacts of the Change While the Notice to Proceed to the Consultant was delayed due to the selection and contracting process, the preliminary design was completed ahead of the LTCP schedule. The 30% cost estimate presented in November 2010 was $9,997,400 as compared to the LTCP cost of $9,556,000. The 30% estimate is slightly above the LTCP cost at the 30% design but does include a 30% contingency. The costs will be monitored at the 60% stage to see how the updated costs compare. However the cost does not meet the 10% increase necessary for a change notification. There are no scope impacts to the Project as a result of this change.

The pre-construction conference was held on April 22, 2010. The Notice to Proceed for construction was given on June 18, 2010. Substantial Completion for construction was issued November 3, 2010. In addition to the changes in schedule, two areas of storm sewer system construction were eliminated from the contract due to field conditions encountered that resulted in the elimination of the need for the storm sewer systems. This result in a reduction of costs. However, unknown underground obstructions were encountered in several areas that increased construction costs to complete the construction as designed.

This change was prepared after completion of the project by the PMT for the purpose of documentation that the actual project construction start was initiated after the LTCP scheduled construction start date but that construction completion was achieved prior to the LTCP project completion date. This change also documents the change in scope of the construction due to discovery of additional sewer systems in the one of the areas that eliminated the need for the designed storm sewer system. This change also documents the additional costs resulting from encountering unknown underground obstructions along the sewer system alignments that necessitated a change in the method of sewer installation and delays associated with the construction. Description of the Change The LTCP schedule identifies the following schedule as shown in Table 1 for the bidding and construction of the SOIASS Street Sewer Separation Project: Table 1: Schedule Changes LTCP Scheduled Completion Actual Completion Bidding 02/5/2010 Council Award 1/12/2010 Construction Notice to 02/8/2010 06/8/2010 Proceed Substantial Completion 11/25/2011 11/3/2010 While the bidding and award of the project was completed ahead of the LTCP date, the Construction Notice to Proceed was delayed due to complications with property acquisition and design revisions of the Darling Inedibles connection. However, the actual Notice of Substantial Completion of construction met the LTCP completion date. The change in cost is due to several factors. Two areas of storm sewer system construction were eliminated from the contract due to field conditions encountered that eliminated the need for the storm sewer systems. A sewer line extension to Darling Inedibles (area 1) was eliminated due to changes in the internal business process flow connections. Storm sewer installations near Omaha Cold Storage (area 5) were also eliminated through a Change Order due to the discovery of a separated system on the business site. These two changes reduced the project cost by approximately $477,000. - 2 - ______ CSO! Program Office: Central Park Plaza, 222 S. 15TH St., Suite 1406S, Omaha, NE 68102 (402) 341-0235 • [email protected] • www.omahacso.com In addition, unknown underground obstructions were encountered in several areas that increased construction costs to complete the construction as designed. Buried remnants of the old Omaha Stockyards were encountered that necessitated a change in the construction methods from trenchless technologies to open cut construction. Justification SCHEDULE - The bidding for the project was completed ahead of schedule as shown in the above Table 1. Property acquisition complications developed due to the number of acquisitions and coordination with railroad entities. Notice to Proceed to the Contractor was issued on June 8, 2010. (See Attachment 1) Actual substantial completion was issued on November 3, 2010. (See Attachment 2) The LTCP completion date is November 25, 2011. Even with the delay in the start of construction, the construction was completed ahead of the LTCP schedule completion date. SCOPE - Storm sewer construction was eliminated in Area 1 because it was determined that a sewer extension to Darling Inedibles was not needed. Area 5 was eliminated from this project because it was determined that the storm runoff from Eckrich’s parking lot does not reach the process line and ultimately does not reach the packinghouse line. The new storm sewer was therefore not required. COST – The LTCP Base Construction Cost for the SOIASS project was $5,218,000. The anticipated final cost for the construction is approximately $1,900,000. Impacts of the Change While the start of construction was delayed, the LTCP construction schedule included sufficient contingency in the construction schedule to accommodate the delay. During the construction, additional investigations of the private property sewer system in the field identified the sewer system was configured differently than originally communicated by the businesses which resulted in eliminating the need for some sections of the proposed storm sewer connections. This resulted in cost savings to the Program and a reduction in the duration of construction. However this reduction in construction duration was partially offset by the delays and additional cost caused by encountering unknown underground obstructions during construction of other sections of the project. Even with the changes encountered on the project, the project was completed within the LTCP completion date and under the LTCP budgeted construction cost.

Participants in the meeting are listed above. A copy of the meeting agenda is attached (Attachment 1). This meeting summary documents the major points of discussion at the meeting. Action items are noted in bold. Any comments on this summary should be sent to Chris Koenig. Purpose of the Meeting Chris Koenig noted that the purpose of this meeting was to discuss the status of field investigations being completed by the City, confirm the recommendation contained in the Preliminary Design Memorandum for the Spring Street Sanitary Sewer Separation project and define the project schedule. Rick Murch said the City has worked on cleaning the existing outfall and re-grading a ditch to the Missouri River. They have done a visual inspection from either end of the outfall pipe, but have been unable to complete a television inspection at this time. Overall the outfall appears to be in good condition. The City will provide further information after the television inspection has been completed. The existing Spring Street Pump Station is usable, but replacement parts for the pumps are difficult to obtain. The pump station will need upgrades of the pumps and control panel as well as other improvements to be brought up to code. It was discussed whether it would be the responsibility of the City to provide a new sanitary sewer service to Building D on the BNSF property. -LP7KHLOHUVDLGWKH&LW\·VSROLF\ZLWK sewer replacement projects has been to provide a service connection for every existing sanitary connection. He recommended first asking BNSF if they would be agreeable to 2010 1 14 - PROJECT COORD MEETING SUMMARY.DOC 1 PROJECT COORDINATION MEETING FOR SPRING STREET SANITARY SEWER SEPARATION abandoning the service to Building D. If not, the City could provide a stub out connection with a two-way cleanout on the proposed sanitary line that BNSF would be responsible for connecting to. It was noted that as part of the project, modifications would be made to the outfall. Pat Nelson stated that this may need a 404 permit from the Corps. She noted that while this could be covered under a nationwide permit, there are concerns that the Corps may view all of the projects along the Missouri River as one. A general regulatory meeting is being scheduled with the Corps. There was a mention of federal stimulus money possibly becoming available for this project. If so, additional requirements may be placed on the project. Wrap Up and Action Items Design will proceed with the recommended option of constructing a new sanitary sewer. HDR will revise the TM on the Preliminary Design to address the changes. Pat Nelson noted that this project was used as the start of the Phase 2 Sewer Separation in the LTCP which means the project needs to go to bid by January 1, 2011. A request for schedule revision will be submitted by HDR to the PMT. Plans will be prepared for submittal to the NDEQ by March 1, 2010 and the project will be scheduled for bid in April 2010. Design for upgrades to the pump station and modifications and/or repairs to the outfall pipe and channel will be completed at a later date and will be coordinated with the South Interceptor Force Main Project. HDR: HDR will contact BNSF to update them on the proposed design and coordinate the future of sanitary sewer service to Building D. A request to abandon the service will be made. HDR will proceed with scheduling additional survey in the BNSF yard and of the existing Spring Street Pump Station. HDR will follow up with the Zoo and NDOR to let them know the status of the project and the proposed design. Updated information will be provided to the utility companies and the existing fiber optic line running along the railroad tracks west of the levee will be located. City of Omaha/Program Management Team: Complete television inspection of the outfall pipe to confirm suitability for use. PMT Compliance team will be meeting with the Corps of Engineers and will provide direction to HDR on permit requirements for the Spring St. Project. 2010 1 14 - PROJECT COORD MEETING SUMMARY.DOC 2 !"# $% % % % ! &' & ' ' ' (' & &' ) & '& & *+ ,' ' & && - ,&& &, .' /01 '2 /01&(' & $/0 &,2 % && 2& . 2 &' , & .%& 3 .'& %& && - 2&' . 4 ' # ,2 (' && &' % " !# ! $ %%& ' & 2., & . & * + &5 , & $ 6 & $ #7 , 2 ' &, $ 6% & , ' &3 8 & . ,&& ' & , & %& ,, 2 & & & &7 , & '& &5 %9&& & '&,2 & ' '2 && ' 2 & & ' & '25 '% 4- 2 & ' '2-' '& %: ' 2 & '-&,' & ; , & %& ' '& , ' &,2 &, &% < ' & &5 & 2., & $ 6< , & $ 6 '2 &%< &5 $ 6 , '' 2 5 2 &5 ' , '% (" !$! & ! 3 & , , / ' , 26 8*&+%& ' =&' &(' , - && %& ' 3' & % .
