7 I. Introduction A National Pollutant Discharge Elimination System (NPDES) Permit for City of Omaha Combined Sewer Overflows (NE ) issued by the Nebraska Department of Environmental Quality (NDEQ) was reissued in 2015 and is effective from October 1, 2015 thru September, This Annual Report is for the period of October 1, 2015 through September 30, 2016 and is submitted in accordance with the CSO Permit in effect for that period. The report meets the requirements of the permit, which is to submit a report within 90 days following each yearly (Oct 1 Sept. 30) anniversary. Throughout the report, the permit will be referred to as the CSO NPDES Permit or CSO Permit. All references to the CSO Permit are to that permit which was in effect from October 1, 2015 to September 30, The CSO NPDES Permit contains the following language: 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. Under the CSO Permit the City has 26 permitted CSO outfalls; 16 of these are associated with the Missouri River Wastewater Treatment Plant (MRWWTP) collection system, the other 10 are associated with the Papillion Creek Wastewater Treatment Plant (PCWWTP) collection system. At this time only CSO 102 at the MRWWTP undergoes treatment prior to discharge. 1 This Annual Report includes actions, activities, and measures taken by the City of Omaha with regard to the Nine Minimum Controls (NMC), the Long Term Control Plan (LTCP) and its compliance schedule, CSO outfall monitoring and in-stream monitoring,. The last section is reserved for other information and includes narrative on reduction of overflows and deactivated CSO outfalls as well as any other information that benefits measuring the success of achieving improved water quality. Added this year is a Performance Report section for CSO outfall overflow accounting; any evaluations of controls achieving their intent; and demonstration of CSO overflows a result of a wet weather event. The Environmental Services Branch 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 consultant engineers and City staff that make up the CSO Program Management Team. 1 The MRWWTP manages CSO Outfall 102 which, under approved conditions, discharges combined wastewater that has received primary treatment but not secondary treatment I-5

9 II. Executive Summary The 2016 CSO Annual Report summarizes information on activities, actions, and measures taken by the City of Omaha and the CSO Program Management Team (PMT) to comply with the CSO NPDES Permit. This includes efforts to maintain and manage the combined sewer treatment and collection system, as well as details on the implementation and management of the CSO LTCP. This section of the report is for the Executive Summary and information here is provided in six sections that follow the annual reporting requirements in the CSO NPDES Permit. These Sections are: Nine Minimum Controls ( NMC) LTCP Documentation Compliance Schedule CSO Outfall Monitoring In-Stream Monitoring Other Information Other information includes measures of success and other requested information that demonstrates the effective management of the wastewater collection and treatment systems in the Combined Sewer Service Area. In particular are summaries on reduction of CSO points and occurrences, other sewer separation projects to primarily relieve basement backups, and materials management associated with the construction projects. A. Nine Minimum Controls (NMC) The CSO NPDES Permit defines Nine Minimum Controls as 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 plan, and work toward the goal of reducing CSOs and improving water quality. Following is a list of the NMCs along with a brief statement on items of relevance during this report period: 1. Proper Operation and Maintenance (O&M): As per standard practice, the Quality Control Division, the Sewer Maintenance Division, and the Wastewater Treatment Plants review the procedures relative to responding, and minimizing CSO impacts. The update for this year was slight modification to the Sewer Maintenance Call-out procedures for after-hours response and an update to the notification procedure for dry weather sewer overflows, provided in Attachment Maximizing the Use of the Collection System for Storage: As part of the compilation process of the annual report, the original NMC plan was revisited and assessed for adherence to the plan. This included a review of EPA s CSO Technology Fact Sheet (EPA 832-F ). Large diameter pipe cleaning has been given more emphasis this year. No other simple modifications were identified for the system. The City will continue with their current practices to maximize the use of collection system by identifying and removing obstructions and addressing inflow and infiltration reduction. 3. Review and Modification of Pretreatment Programs: current practices to minimize impacts of industrial facilities continue to be followed and are administered through the Quality II-7

10 Control Division (QCD). A total of 13 NPP permitted facilities are located in the CSS area and were operating during this permit year. 4. Maximization of Flow to the POTWs for Treatment: existing policies to maximize flow to the Missouri River Wastewater Treatment Plant and Papillion Creek Wastewater Treatment Plant are in place. As a goal for this NMC, the City continues to consider opportunities to maximize treatment of wet weather flows. The City also understands that more complex modifications are required at the WWTPs to receive additional flow and will pursue these goals more fully under the LTCP. During this reporting year, no additional simple modifications have been identified that would further maximize flow to the treatment facilities. 5. Prohibition of CSOs during Dry Weather: is a control that continues to be a high priority focus with strict response, reporting, and tracking processes. Five (5) overflows in the system were contained or re-entered the system and continued to treatment. Ten (10) overflows were reported during dry weather that reached waters of the State. 6. Control of Solid and Floatable Materials in CSOs: Simple measures were determined not feasible in the NMC plan and that more complex solutions need to be evaluated. The LTCP efforts will carry out proper evaluations as projects are implemented. No additional processes or controls have been implemented to the system this year with regard to solid and floatable materials. 7. Pollution Prevention: The management of this item is shared between several Divisions and work groups within the City. The City of Omaha municipal separate storm sewer system (MS4), details much of the efforts in an annual report, including inlet cleaning and grit removal. Efforts continue with Papillion Creek Watershed Partnership and Keep Omaha Beautiful for storm water pollution prevention and outreach. No additional pollution prevention measures have been implemented during this report period. 8. Public Notification: The Standard Operating Procedure (SOP) for Reporting and Public Notification of Dry Weather Sewer Overflows and Bypasses was followed for the year and had no media releases. CSO signs posted at each outfall continue to be maintained per standard procedure; however responsibility has moved to staff at Sewer Maintenance. Additional public information is continually available through a public website as part of the CSO Program. Section B of this executive summary contains information on the Public Participation Plan. 9. Monitoring to characterize CSO impacts and the efficacy of CSO controls: The City of Omaha continued to maintain and record combined sewer overflow events at the designated outfalls in the system. During this report period, there were no known beach closings or fish kills. There are no records of any wash-up of floatables. One significant rain event on August 28, 2016 resulted in nine (9) system backups into properties or establishments and 1additional on May 11. These records are documented and tracked by the Sewer Maintenance Division. Engineering staff evaluate the site and system conditions that may have contributed to the CSO Impacts on private properties. In some cases, back water valves are recommended and approved, in other cases a sewer system evaluation survey is completed and potentially identified for a capital project. II-8

11 B. 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. Included is a list of the required reporting elements under LTCP Documentation along with a brief description any items of significance for each element. 1. Characterization and Modeling of the CSO System. The combined sewer system (CSS) is sufficiently mapped in GIS with regular updates occurring as field differences are discovered or per as-built record drawings. Information from design consultants is incorporated into the City s GIS and Infoworks CSS model as final designs become available. Other characterization efforts of the CSS include water quality monitoring of select outfalls (CSO 102 at this time, with future plans at CSO 205), gathering of field data in project areas, and overflow occurrence monitoring at CSO points through the CSO Block program. The City continued flow monitoring of the Papio Interceptors, adding 3 permanent meters to the Cole Creek system. For the reporting year, there were 20 permanent flow monitoring sites, 50 temporary for the CSO model, 9 sites to support the inflow and infiltration study upstream of South Omaha Industrial Area Lift, and 17 additional sites for inflow and infiltration studies in sanitary systems along Little Papio Interceptor, upstream of CSO 205. Additionally, the City gathered precipitation data using 9 permanent city-managed and 8 temporary consultant-managed rain gauges, and a project for radar rainfall processing to support the CSO monitoring this report period. 2. Public Participation Plan. The City continues to maintain Lovgren Marketing Group as the Public Participation Coordinator during CSO implementation. This group coordinates many activities with the media, public officials, stakeholders, and other opportunities for public outreach. The focus is centered on two major efforts: (1) continued involvement, education and acceptance by the public about the need for the CSO Program and (2) the progress on the specific projects, in particular during construction. A detailed summary in in Attachment Consideration of Sensitive Areas. No additional sensitive areas have been discovered during this report period. 4. Evaluation of Alternatives. The City and PMT are in the process of re-evaluation of several of the projects in the Minne Lusa and Saddle Creek basins. These projects are being reevaluated as a result of significant cost increases that resulted in the projects as developed longer be justified based on the Cost/benefits assumed for the LTCP. The PMT is currently evaluating possible alternatives that will achieve the regulatory requirement of 85% volume capture that are more cost effective. The City hopes to inform NDEQ of the project(s) to be implemented in the Saddle Creek Basin in early 2017 and in the Minne Lusa Basin in early In addition to these areas, the City is implementing an ongoing process that will review future projects to ensure that the projects envisioned in the 2009 LTCP and subsequent update in 2014 is still the most cost effective to address the CSOs. 5. Cost/Performance Considerations. On July 15, 2014, the City Council adopted an updated ordinance that established sewer rates for the period A financial capability assessment for Omaha s wastewater enterprise fund was completed in May In 2016, Omaha contracted with a consultant to update the City s Rate Model that was originally II-9

12 developed in 2006, and to perform a Financial Capability Assessment (FCA) to prepare for the next rate ordinance in This will assist the City in working with NDEQ to establish a framework to address issues related to Affordability of the program. It will also assist the City in estimating the impact of other regulatory and infrastructure needs that sewer fees must pay for. The most current estimate on the overall cost of the program is slightly over $2.0 billion. 6. Operational Plan. On November 13, 2015 a wet weather operations protocol was submitted to NDEQ. The Plan included a summary of the anticipated operation of the Plant once the construction is complete. The figure below includes the process flow during wet weather. The Municipal Headworks is in service receiving flows from the Monroe Street Lift Station and the In-Plant Lift Station. The Monroe Street flow is not represented separately on the diagram. The additional operational changes correspond to the completion of the Schedule B2 improvements when a post primary disinfection system is in place which will be in In addition, modifications to the plant to be able to treat 64 MGD through secondary treatment, and 150 MGD through primary are complete. However, until the SIFM is complete, the maximum flow will not be achievable. Figure ES 2-1: MRWWTP Operational Plan 7. Maximizing Treatment at the Existing POTW Treatment Facilities. Major projects are planned during the next 5 years to maximize treatment of combined wastewater at the MRWWF. The City of Omaha continues to evaluate opportunities to maximize treatment at the MRWWTF as part of the adaptive management strategy for implementation of the LTCP. No new approaches have been identified during this report year. Projects related to current strategy are discussed in more detail in the relative progress report in Attachment 4. Any expansion of the treatment capacity of the PCWWTF is scheduled for evaluation after this permit term. II-10

13 8. Implementation Schedule. During this permit reporting period, the City continued to implement projects and to work toward a schedule compliant with the 2027 deadline. The City developed a LTCP Update implementation schedule factoring in interrelationships of the projects, priorities, and construction sequencing. The schedule was also adjusted to conform to the City s financing capability and the effects of the extension of implementation brought about by the 2011 Flood. Included in this Annual Report are project specific progress reports on implementation of the CSO major projects and sewer separation projects set forth in the compliance schedule. See Section C of this executive summary for summary of Compliance Schedule. 9. Post-Construction Compliance Monitoring Program. The City s Post Construction Monitoring Program includes Outfall monitoring at designated CSO points, in-stream monitoring, and verification of separation projects. Additional information is provided in the Section E, In-Stream Monitoring and any results of studies performed that support the deactivation of a CSO outfall are included in Section F - Performance Report of the executive summary. C. Compliance Schedule A summary of construction activities, actions, and other measures completed according to the Compliance Schedule for Implementation of CSO Control Projects set forth in Part VI of the permit is included in this annual report. Annual Project Progress Reports are submitted in Attachment 4 for projects that had activity to report. Out of 47 projects listed in the current CSO NPDES Permit, 5 are complete, 14 in progress, and 5 due to have activity this year were placed on hold. Figure ES 2-2: Compliance Status of the 47 listed Projects in the Permit II-11

14 D. CSO Outfall Monitoring 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 complied with these requirements. CSO 102 had 66 overflow events from October 1, 2015 through September 30, Results from the monitoring are reported on quarterly discharge monitoring reports. Interim Requirements for the monitoring of CSO Outfall 205, were not in effect this year. E. In-stream Monitoring The current NPDES Permit requires a summary of instream monitoring data consistent with the Implementation Monitoring Plan objectives to include monitoring station identification, stream identification, the list of parameters along with the monitoring results. It is important to note that although In-Stream Monitoring was included as part of the Draft- Implementation Monitoring Plan, March 2010, it also states in the plan Although not legally required by state or federal regulations, the City has included in-stream water quality monitoring as part of the water quality monitoring plan. An in-stream water quality monitoring network within portions of the Papillion Creek, its tributaries, and the Missouri River will provide water quality data that benefits both the CSO Program and the Stormwater Program. A permit modification was accepted by the NDEQ with regard to the City s MS4 NPDES Permit, April 5, 2016 that modified the Program Elements of the Storm Water Monitoring Plan. With that, the in-stream monitoring was removed from the plan, and alternate elements approved. City staff monitored four sites along the Papillion Creek system and three sites along the Missouri River for water quality parameters. USGS continued water quality sampling for the City at four sites along Missouri River. There are five Missouri River sites altogether counting City and USGS in-stream sampling. Data provided by USGS for 2015 is approved. Data for 2016 is considered provisional. F. Performance Report As stated in the CSO permit, Part VIII, Section E, the performance report consists of A) reporting the number of times each CSO outfall has an overflow and an evaluation as to whether the controls are achieving their design intent. B) Documentation needs to be provided that demonstrates that each CSO overflow occurrence was the result of a wet weather event. C) Once in the term of the permit, provide the percent by volume of the combined sewage collected in the CSS during precipitation events on a system-wide annual average basis that is eliminated or captured for treatment. CSO occurrences at CSOs along Missouri River were highest at CSO 109, MRWWTP, equal to 66 and lowest at Bridge Street equal to 3. Little Papio CSOs lowest count was at CSO 211, 66 th and Pacific, and highest count of 63 at CSO 204, Cole Creek. LTCP Projects are complete for CSO 211 and CSO 103 and these CSOs are being monitored for further inflow reduction. An additional report is submitted this year to show that each CSO occurrence can be attributed to rain or snow melt. See attachment II-12

15 G. Other Information The CSO NPDES Permit, Part VII.F, requires a section of the Annual Report be for other information. The City typically includes information in this section of the report that highlights factors relevant to the CSO Program not reported elsewhere. This section contains measures of success as well as discussion on affordability and other beneficial programs or efforts impacting the success of the CSO Program. Following is a list along with a brief description for each item discussed in this year s report: 1. Missouri River Bank Stabilization: A Project was kicked off this year to provide bank stabilization improvements at the Missouri River Wastewater Treatment Plant (MRWWTP). These improvements are needed in order to protect a portion of the existing MRWWTP and facilitate construction of additional improvements (OPW 52648, Missouri River Wastewater Treatment Plant Improvements Schedule B2: Chlorine Contact Basin and Primary Clarifier Odor control) which are being bid and constructed separately. 2. On September 13, 2016 NDEQ representatives conducted an inspection with regard to compliance with the CSO NPDES Permit. The sites visited were MRWWTP Improvements, Schedule A1 and B1; South Interceptor Force Main-North Segment, and JCB and Miami Sewer Separation. The MRWWTP Bank Stabilization was also among the projects visited. NDEQ noted issues with pollution prevention and uncovered trash containers. Results of the inspection were submitted to the City on October 28, City addressed site issues. 3. NDEQ inspection report suggested documenting improvements and submitting them to the NDEQ. This Annual Report will serve as the response to the comments and suggestions. Attachment 6 is an excerpt from the 60 page NDEQ inspection report submitted to the City along with the City follow-up site inspections. The Construction Managers were onsite during the inspections and were made aware of the concerns with uncovered containers. 4. EPA Coordination Efforts: The City of Omaha continued its partnerships with the EPA Office of Research and Development office in Cincinnati, OH (EPA ORD) and various officials from EPA Region 7. A demonstration project at Sewer Maintenance Division, completed in 2014, includes pervious pavers and bio-retention and is being monitored by the USGS to measure the effectiveness. 5. Reduction in the Number of Overflow Events and CSO Outfalls: CSO 211 diversion structure near 66 th and Pacific had a weir built on the on the outfall pipe and a reduction in CSOs of more than 50% on average. CSO 103 has also shown a significant reduction in the occurrences per rain event. More reduction will happen as the LTCP is implemented. 6. Receiving Water Quality: A significant reduction in E. coli load to the Missouri River occurred with the implementation of the SOIA Lift Station. Another major reduction will occur when the South Interceptor Force Main and Missouri River Wastewater Treatment Plant projects currently under construction are completed.figure ES 2-2 indicates a prediction in the reduction of E. coli loading over time due to the implementation of the LTCP, according to the Update submitted 9/26/2014. II-13

16 7. City of Omaha RNC Program: a program to separate localized combined sewer areas to primarily address basement backups. The projects this year include 49th & Caldwell Area Sewer Separation, almost complete at the time of this report. An additional project in the 18 th and Fort Street area began Sewer System Evaluation Survey, Fall 2015, and continued with preliminary study and design in Figure ES 2-3:E.Coli Reduction over LTCP Implementation 8. Rate Information: In April of 2013 the City s rate consultant issued an updated cost of service study that recommended a schedule of rate increases for the period , approved July In The University of Cincinnati financial capability assessment for Omaha s wastewater enterprise fund, completed May of 2013 remains in consideration for future rate increases. 9. Material Management: During the 2016 reporting year, approximately 29,418 tons of the waste material from construction of capital projects associated with the CSO Program, mainly contaminated soil, were taken to the Waste Management Pheasant Point Landfill. C&D waste was disposed of locally in a C&D landfill. Approximately tons were considered hazardous waste and taken to Waste Management s Emelle, Alabama facility. The City monitors and tracks contaminated soils and other waste material and use this report to update the NDEQ Waste Management Division. II-14

17 III. Nine Minimum Controls As defined in the CSO NPDES Permit, Nine Minimum Controls (NMCs) 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 and the NDEQ have worked together toward implementing NMC s per the EPA Guidance Document 832-B , Combined Sewer Overflows- Guidance for Nine Minimum Controls, which states: The NPDES Permitting authority should develop and issue Phase I NPDES Permits requiring CSO communities to implement the NMCs. The NPDES Permitting authority should develop and issue Phase II NPDES Permits requiring continued implementation of the NMCs and implementation of an LTCP. Minimum Controls are not temporary measures; they should be part of long term efforts to control CSO s. On October 1, 2002, the NDEQ issued a CSO Phase I Permit to the City of Omaha. The Phase I Permit contained a series of required submittals and reporting requirements that demonstrated the development and initial implementation of the NMCs. 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. NE On October 1, 2007, the NDEQ issued to the City a Phase II CSO Permit. The Phase II CSO Permit continued the documentation and reporting requirements to assure the NMCs would be met in accordance with: the initial NMC submittals that were a part of the Phase I Permit, as documented in the 2007 CSO Annual Report; and any modifications or updates to those initial submittals the EPA NMC Guidance the Environmental Protection Agency CSO Control Policy (April 19, 1994, at 59 Fed. Reg ) The City has continued to implement the NMCs in accordance with the submittals on record with the NDEQ, and in accordance with EPA Guidance and Policy. The NMC documentation that follows is written according to the conditions and requirements of Part IV of the CSO NPDES Permit. Additional information beyond the minimum documentation is included as appropriate. III-15

18 A. Proper Operation and Maintenance (O&M) Per the requirements of the CSO NPDES Permit, proper operation and maintenance of the CSS and CSO outfalls should include periodic reviews of O&M procedures, updates to the procedures as needed, and proper documentation of the procedures. A major emphasis is on the elimination of dry weather overflows. Revisions and additions to the O & M procedures are to be included in this Annual Report. The City continues to follow a schedule of semi-annually reviewing procedures that are a part of properly operating and maintaining the combined sewer system. The procedures involved are carried out across several Divisions of City of Omaha Environmental Services. When a significant procedure is changed, updated, or added, the City will provide the required documentation to NDEQ. The following items were addressed as a part of the review process during this report year: The Sewer System Operation and Maintenance Manual for Sewer Maintenance Division (Brown & Caldwell, 2006) is reviewed semi-annually. During this year s review, Appendix H "Call-Out Procedure" was reviewed and amended to clarify procedures in the following sections: "Clearing the Blockage", "Documenting the Backup" and "Pre- Storm Preparation". Additionally, some innovative techniques were incorporated to optimize the jetting program. This involved changes in work management using GIS and Cityworks. The City 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. The NMC Plan for the City outlines the EPA s CSO Technology Fact Sheet, Maximization of In- Line Storage (EPA 832-F ) which lists the following list of typical control measures for increasing in-system storage: Inspection of the collection system and removal of obstructions; Maintenance, repair and replacement of tide and control gates; Installation and adjustment of regulators; Reduction/retardation of inflows and infiltration; Upgrade/adjustment of pumps; Real-time monitoring. The City has standard practices and procedures in place that correspond to these measures. The following is a brief summary of practices within the City to contribute to maximizing the use of collection system: III-16

19 Inspection of the collection system and removal of obstructions: Sewer Maintenance Division is primary organization involved with maintenance of the collection system. Environmental Quality Control Division inspects and maintains lift stations. Procedures are in place to identify and provide corrective maintenance which includes inspection, cleaning, and removing blockages. Corrective repairs to inlet, manholes, and pipelines are also performed. Five year cycle jetting program for 15 and smaller pipes, and a reactive preventative maintenance program are among the practices to meet this control. The City contracts services to clean some large diameter pipelines. Maintenance, repair, and replacement of tide (river) and control gates: In the Missouri River Watershed, gate inspections occur once every year, at a minimum, with appropriate actions to follow. Installation and adjustment of regulators: Previous studies have indicated that there is very little in-line storage in the Missouri River Watershed. However, the Papillion Creek Watershed does utilize regulators to maximize in-line storage in the interceptor, and maximize the amount of wet-weather that goes to the PCWWTP. The use of the sewer model and other technologies to optimize the system that go beyond the NMC requirements may be pursued in the future as a part of the City s Adaptive Management strategy as part of the LTCP. The City will evaluate the addition and modification of regulators on a case-by-case basis Reduction and retardation of inflows and infiltration: Inspections of sewer structures contribute to a program plan to remove inflow sources and rehabilitate a portion of the sewer each year. Reduction efforts include vented manhole cover replacement, sewer lining, localized sewer separation, and enforcing private property defect repairs and illicit connections. In addition, stormwater management practices, such as detention ponds, are in place. The City continues to include and evaluate these methods of inflow reduction in management of the CSS. Upgrade/adjustment of pumps: The City Quality Control Division maintains the pumps stations associated with the CSO system. Personnel are responsible for maintaining pumps as necessary to ensure that the stations perform as designed. Upgrades to Variable Frequency Devices (VFDs) have occurred at lift stations as needed since 2004 as continuation of this nine minimum control. Real-time monitoring: The Operators at the MRWWTP are responsible for monitoring the SCADA system 24 hours/day. Most remote stations are on the SCADA system; the remainders have auto dialers. The system includes gates that are controlled remotely to maximize flows into the plant. The City will review the items listed in the EPA Technology Fact Sheet to see if additional items may be implemented as a part of the NMCs to improve in-system storage. No modifications were made to this NMC during this report period, however it has been identified that the combined sewer system, larger diameter pipelines, require a more concerted effort for inspection and cleaning. III-17

20 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 by 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. A total of 13 NPP permitted facilities are located in the CSS area and were operating during this permit year. These facilities are listed in Table 3-1. Table 3-1: NPP Industries in CSS Name Address CSO area Regulated Batch Discharges E. A. Pederson 3900 Dahlman Avenue 118 No G&G Mfg 4432 McKinley St. 103 Yes Industrial Plating 1149 Florence Blvd. 108 Yes Koleys 2951 Harney St. 108 Yes Lindsay Corporation 505 Crown Point 106 Yes Lozier Corp John Pershing Dr. 107 Yes ABS Corp No. 16th St. 107 Yes Lozier Corp No. 22nd St. 106 Yes Modern Equipment Company, Inc Abbot Drive 107 Yes Roberts Dairy 2901 Cuming St. 108 * Armour Eckrich Meats LLC 5015 So. 33 rd St. 119 * Silverstone Inc McKinley St 103 Yes Syngenta Crop Protection, Inc 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. 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 related to the CSS and the measures taken to correct the cause of the overflow and report 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 response, documentation, and reporting of dry weather overflows in an effort to prevent, where possible subsequent events. Reported in Table 3-2 and Table 3-3 are summaries of the dry-weather overflows discovered III-18

21 during the report period. The additional information for each event was submitted to NDEQ, in accordance with reporting requirements in the CSO NPDES Permit. Overflows that reached waters of the State (W.O.S.) either directly through the permitted CSO discharge point, or by a waterway or nearby separate Storm Sewer were ten (10) total: o o o o o 1 related to an illicit sewer service connection to a CSO outfall leading to CSO due to construction operations failure 3 due to power failure 3 due to grit and debris 1 at MRWWTP, the East Grit Basin at the North Inlet headworks was taken out of service on November 24, 2015 due to a break or hole in the grit draw off line under the basin (suspected but not yet confirmed) No leak has occurred since that time and the existing facilities at the plant have been able to meet all capacity requirements. Extensive excavation under an existing, pile supported basin needed to confirm potential major rehabilitation. Overflows that were contained and did not reach a water body were five (5) total: o o o 3 confined to private property generally in the form of a basement back-up 1 was related to the Martha Street pump station and contained using a vacuum truck 1 escaped the system through a manhole but dried before it was able to migrate One additional report was sent to NDEQ June 21, 2016 for a basement backup at 7607 N 29 th St but has been determined due to a private issue with failure to maintain backflow prevention valve.

23 E. 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. Based on previous evaluations, many of the CSO points are not conducive to the implementation of floatable controls without significant modification. Mechanical bar screens are at CSO 106/107 in the early 2000 s at North Interceptor/Grace Street, and CSO 108 Burt- Izard Lift Station. These sites continue to be maintained by the City Quality Control Division. No additional processes or controls have been implemented this year with regard to solids and floatables control. The CSO LTCP is intended to provide for adequate control of solids and floatables throughout the system, with improvements being implemented over time as projects in the LTCP take place. F. 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. Modifications are documented in this Annual Report. In 2005 and 2006 as a part of the City s initial NMC development, the City evaluated various methods for maximizing flow to the WWTPs. Much of the evaluation supported the decisions that resulted in the LTCP; however some operational changes were made immediately to allow for better wet weather management and improved water quality. As a goal for this NMC, the City continues to consider ways for maximizing treatment of wet weather flows. The City also understands that more complex modifications are required at the WWTPs to receive additional flow and will pursue these goals more fully under the LTCP. During this reporting year, The City of Omaha completed the construction of a new Municipal Headworks Facility. This facility increases plant hydraulic capacity to a peak sustained hour flow of 150 MGD. Additional modifications to the pump stations in the system and the completion of a new force main to the facility will allow the plant to increase wet weather flow to the plant during wet periods. These modifications will take over the next several years. Some Large Diameter pipe cleaning took place this year and may aid in maximizing flows to the treatment plant. No other additional simple modifications have been implemented that would further maximize flow to the treatment facilities. III-21

24 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. Pollution prevention efforts are shared between several Divisions and work groups within the Public Works Department. Most 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 NE Specifically, the MS4 annual report contains a section on Pollution Prevention/Good Housekeeping and includes a summary of storm sewer cleaning and other sewer maintenance records as well as street sweeping efforts. Additional measures for pollution prevention include shared duties between the Sewer Maintenance Division and the Quality Control Division for sewer system grit removal. In general, the Quality Control Division is responsible for the maintenance of structures associated with the CSO lift stations, the CSO screens located at CSO 106/107 and CSO 108, and aerated and non-aerated grit facilities associated with some of the larger CSO points. Sewer Maintenance is responsible for maintenance of small grit pits located thought the collection system, with some of these being associated with diversion structures and pits located near the smaller CSO overflow points. Each Division is responsible for recording and documenting their own activities. Quality Control Division maintains these records in a log located at the MRWWTP. The Sewer Maintenance Division records work in asset management system. 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. 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. Locations of CSOs have been identified for the public through specific signage posted near the outfalls, as well as along marina locations and public trails that parallel receiving streams. Per standard procedure, signs at the CSO outfalls are inspected twice per year for visibility and condition. Procedure responsibilities continue to be carried out by Sewer Maintenance Division staff. All CSO signs were inspected by the Sewer Technical Services Group at Sewer Maintenance and completed on 12/03/2015 and 04/30/2016. Signs were replaced or repaired where necessary and all required signs are in place. III-22

25 The Public is not directly notified of each individual occurrence of a rain induced CSO. Rather the public is informed and educated through several means of media and public outreach, reminding the public of the nature of combined sewer overflows and the impacts or effects to receiving streams. The signs posted at each outfall follow this template: COMBINED SEWER OUTFALL CSO ### DISCHARGE MAY INCLUDE UNTREATED SEWAGE UNDER WET-WEATHER CONDITIONS FOR INFORMATION OR TO REPORT PROBLEMS CALL CITY OF OMAHA QUALITY CONTROL DIVISION For occurrences of dry weather overflows, overflows that continue after the effects of wet weather have subsided, or any other instance of a non-permitted overflow or bypass, the City follows reporting requirements outlined in the Standard Operating Procedure (SOP) for Reporting and Public Notification of Dry Weather Sewer Overflows and Bypasses. This SOP has been reviewed, with no changes or updates required. No other policies or procedures for Public Notification have been revised or updated. All public notifications related to significant dry weather overflows are submitted under Attachment 2 of this report. For this report year no such notices were warranted per the criteria set forth in the Standard Operating Procedure (SOP) for Reporting and Public Notification of Dry Weather Sewer Overflows and Bypasses. Under LTCP Documentation for Public Participation and in Attachment 3 of this report, a summary is provided that documents methods of informing the public with regarding to understanding CSOs and the CSO program. 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. Information on efforts made during implementation of the LTCP to characterize the CSS system can be found in Section IV. A. Characterization and Modeling of the CSO System. No additional CSO outfalls were identified during this reporting year. However, one sanitary service connection was discovered connected to the CSO 212 outfall pipe as previously mentioned in Sub-section D- Prohibition of Dry Weather. Monitoring of CSO impacts is reported in this section as per previous years reporting. The efficacy of CSO Controls is now detailed in a new section, Section VIII-Performance Report. Monitoring of CSO Impacts During the implementation of this NMC, in early 2000s, under requirements of a preceding NPDES Permit, a report to record beach closings, wash-up of floatables, fish kills, hazards to navigation, and basement flooding caused by CSO events was established. The following is provided to meet this requirement: In the period of October 1, 2015 to September 30, 2016, there were no known beach closings or fish kills. There are no records of any wash-up of floatables. III-23

26 The City recorded a total of ten (10) known occurrences where combined sewage escaped the system, not at a permitted CSO point. These occurrences were rain related backups into a property. These occurred during the storm events outlined in Table 3-2. The reported events are listed in Table 3-3. Table 3-4: Storm Events that caused Basement Flooding Date Duration Total Rainfall (Inches) Reoccurrence Interval (NOAA) (Hrs) May 11, >1 year Summary: Peak intensity of 0.42 inches per hour August 23, year Summary: Peak intensity of 2.72 inch per hour.

In some cases, back-water valves are recommended and approved. In other cases, the need for a sewer system evaluation survey is identified. The City utilizes all gathered information to determine if a capital project may be required, or if modifications to O&M procedures are needed. A goal is to identify and address persistent or chronic impacts into private properties. III-24

27 IV. LTCP Documentation The City of Omaha submitted the complete LTCP to the NDEQ on Sept. 25, 2009, in fulfillment of NPDES Permit requirements and the CSO Control Policy. The LTCP was subsequently approved by the NDEQ on February 10, An Update to the Long Term Control Plan was submitted to the NDEQ on Sept. 29, 2014, which was approved by the NDEQ on Jan. 23, Minor modification to the Update to the Long Term Control Plan was approved by the NDEQ on April 3, The City of Omaha shall submit documentation and reports applicable to the LTCP in the Annual Report according to the conditions and requirements specified in the Permit. The following nine sections in this Annual report address those requirements and are presented in the order found in the outline in Part V of the Permit. A. Characterization and Modeling of the CSO System As stated in the CSO NPDES Permit, protocols for characterization, monitoring, and modeling of the CSS is included in Section 2 of the LTCP Baseline Conditions/Study Basins Descriptions. This section of the LTCP addresses the response of the CSS to various precipitation events, identified the number, location, frequency, and characteristics of CSOs, and identified water quality impacts that resulted from CSOs. The City of Omaha shall continue to characterize, monitor, and model the CSS as set forth in the LTCP. A narrative summary of changes to the characterization, monitoring, and modeling of the CSS as construction projects and sewer separation projects are implemented shall be included in the Annual Report. The CSS is almost completely mapped in GIS with regular updates occurring as field differences are discovered or per as-built record drawings. The CSO system continues to be further characterized as the projects that make up the LTCP are designed and implemented. 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 sanitary and combined sewer system computer model to ensure that the level of control specified in the LTCP is achieved. 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 During the NPDES Permit renewal it was demonstrated that most of the CSO outfall samplings were erratic and would be inconclusive over the long term due to the nature of the various rain events. Only CSO 102 at the MRWWTP maintains discharge sampling. 2. Documentation and recording of additional collection system information: 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. In addition, the City conducts their own Sewer System Evaluation Studies (SSES) either with City staff or through a managed Field Services contract. The findings of the studies are incorporated back into the City GIS and result in updated sewer mapping. IV-25

28 3. CSO Block Program: The City maintains a block program also commonly referred to as CSO device checks. Under this program a block or some type of device is placed to indicate if there is an overflow. Section VII - Performance Report will report further on the results of this Program. 4. Flow monitoring: Temporary and permanent flow monitoring continues in both the CSS and Sanitary collection system to support long term planning and individual projects. Rainfall monitoring is included in this effort. Monitoring Efforts The City has been performing flow monitoring of its combined sewer system, specifically related to the characterization of the system, since The City continued city-wide flow monitoring of the Papio Interceptors, adding 3 permanent meters to the Cole Creek system. For the reporting year, there were 20 permanent flow monitoring sites, 50 temporary for the CSO model, 9 sites to support the inflow and infiltration study upstream of South Omaha Industrial Area Lift, and 17 sites for inflow and infiltration studies in sanitary systems along Little Papio Interceptor, upstream of CSO 205. Additionally, the City gathered precipitation data using 9 permanent city-managed and 8 temporary consultant-managed rain gauges, and facilitated a project for radar rainfall processing to support the CSO monitoring. Sewer Maintenance Division coordinates with the CSO Program Management Team and other City Divisions to plan the flow and rain monitoring program and meets the needs of the CSO Program. Figure 4-1 provides a location map for the flow monitors and rain gauges including locations of Papio NRD Alert Rain gauge system which is used to supplement the City s network.

33 Modeling Efforts The City is continuing to utilize and upgrade its sanitary and combined sewer system model (SCSS model) during the implementation phase of the CSO program. This model, which was first built in the years prior to the planning phase of the CSO LTCP, previously utilized the InfoWorks CS software platform but was upgraded to InfoWorks ICM in the last year due to requirements from the software vendor. Updates to the model are made on an ongoing basis. The updates occur as additional information on the system is discovered, and as the system is modified as the CSO controls are implemented. Additionally to these upgrades, the City is working towards a goal to provide more detailed information on the CSS in the upstream areas of the watersheds/sewersheds. This added detail will better allow for the evaluation of the effectiveness of Green Infrastructure and/or stormwater control measures that are intended to control the stormwater as close to the source as possible. The model, when originally built, focused on detailed information and calibration at the CSO outfalls, and included information on pipes with diameters of 24 and larger. As upgrades are made over time, the model will provide coupled modeling of the surface and subsurface flows, including inlets and smaller pipes (diameters of 12 inches and greater). The model will better support decisions on CSO controls, and will provide more reliable information on the impacts in the CSO basins where combined and storm sewer systems are operating side-by-side. Upgrades to the level of detail in the Burt-Izard, Minne Lusa, Leavenworth, South Interceptor, Ohern/Monroe, Cole Creek, and Saddle Creek Basins are ongoing. In December of 2015, a substantial effort to obtain sewer data from maps and input the data into the City s GIS was completed. Questions raised during that effort have been investigated on maps and in the field. Model data obtained from the updated GIS and field investigations were vetted in InfoWorks ICM in early Flow monitoring at 51 temporary meter locations was conducted April through August of Rainfall data were also acquired, and radar processing of the rainfall data is ongoing during the fall of The flow and rain data will be used to check and adjust the updated model s calibration. In addition to the Program level work, models of smaller areas are created as part of many of the design efforts for individual projects under the CSO Program. A Hydrologic and Hydraulic Modeling Approach technical memorandum is developed by the design consultant to ensure consistency with CSO Program goals. The details added to these models are included where deemed appropriate in the City s SCSS model. 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. The City continues to maintain Lovgren Marketing Group as the Public Participation Coordinator during the CSO Implementation Phase. Public participation continues to focus on two major efforts: the continued involvement, education and acceptance by the public about the need for the CSO Program; and the progress on the specific projects within the Long Term Control Plan. IV-31

34 The Program and Projects were showcased at public meetings, neighborhood associations and alliances, civic organizations, professional conferences and events to provide a broad view of Omaha s effort to meet regulatory compliance. A Public Participation Report produced by Lovgren Marketing Group, provides a more detailed summary of efforts during the reporting period and is included as Attachment 3. C. Consideration of Sensitive Areas The identification of sensitive areas to which the CSOs discharge is included in Section 2 of the LTCP Baseline Conditions/Study Basins Description. (See also Update to LTCP 2014) Sensitive areas include water with threatened or endangered species and their designated critical habitat, waters with primary contact recreation, public drinking water intakes, and any other areas identified by the City of Omaha or the NDEQ in coordination with other State or Federal Agencies. The CSO NPDES Permit states that the City of Omaha provide any changes to the status of previously identified sensitive areas in the Annual Report. At this time there are no changes. D. Evaluation of Alternatives The process that the City of Omaha undertook to identify, screen, evaluate, and select CSO control technologies and alternatives for the Missouri River and the Papillion Creek watersheds is included in Section 3 of the LTCP CSO Control Alternatives Evaluation. (See also Update to LTCP 2014) This process resulted in a group of selected CSO controls that includes two retention treatment basins, upgrades to the MRWWTF, replacement force mains, a deep tunnel for storage, green solutions, and sewer separation projects which are anticipated to satisfy presumption approach of the CSO Control Policy and will not preclude meeting WQS. The CSO NPDES Permit requires any significant changes or revisions to the controls set forth in the LTCP shall be submitted by October 1, 2019 to the NDEQ for review and approval according to the Part IX (F) Revisions to the Long Term Control Plan. The City and PMT are in the process of re-evaluation of several of the projects in the Minne Lusa and Saddle Creek basins. These projects are being re-evaluated as a result of significant cost increases that resulted in the projects as developed longer be justified based on the Cost/benefits assumed for the LTCP. The PMT is currently evaluating possible alternatives that will achieve the regulatory requirement of 85% volume capture that are more cost effective. The City hopes to inform NDEQ of the project(s) to be implemented in the Saddle Creek Basin in early 2017 and in the Minne Lusa Basin in early In addition to these areas, the City is implementing an ongoing process that will review future projects to ensure that the projects envisioned in the 2009 LTCP and subsequent update in 2014 is still the most cost effective to address the CSOs.. IV-32

35 E. Cost/Performance Considerations An evaluation of the benefit cost ratios for CSO control levels and financial capability analysis is included in Section 3 Control Alternative Evaluation and Section 6 Financial Capability Evaluation of the LTCP. (See also Update to LTCP 2014) The CSO NPDES Permit requires that the City of Omaha submit a financial report to the NDEQ by October 1, 2019; that sets forth a strategy to obtain sufficient revenue to fund the CSO program through at least the year 2024 that includes funding for the specific projects in the Implementation Schedule, Section 7 of the LTCP and 2014 Update to LTCP. In 2016, Omaha contracted with a consultant to update the City s Rate Model that was originally developed in 2006, and to perform a Financial Capability Assessment (FCA) to prepare for the next rate ordinance in As part of the Rate Model Update, assumptions used to develop the original model are being examined and updated as needed. This includes assumptions related to cash reserves, customer growth rate, cost of borrowing money, utilization of State Revolving Fund loans, rate of inflation, O&M costs, and others. The current contract does not include updating the cost of service evaluation, or setting rates for the next Rate Ordinance; however, the existing Rate Model will be made much more user friendly, allowing what-if scenarios for future rates impacts to be more easily evaluated. The FCA is evaluating the burden of currently planned sewer rate increases on the Omaha community as a whole, and on various sectors of the community. This will assist the City in working with NDEQ to establish a framework, as noted in the paragraph above, to address issues related to Affordability of the program. It will also assist the City in estimating the impact of other regulatory and infrastructure needs that sewer fees must pay for. F. Operational Plan The CSO NPDES Permit required the City to update the Monitoring Program and CSO Wet Weather Operations Plan as CSO controls are constructed and sewers are separated. Current language in the permit also requires that by September 30, 2015, the City shall submit 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. This submittal was provided on November 13, 2015, as allowed by the NDEQ. The Plan included a summary of the anticipated operation of the Plant once the construction is complete. It is important to note that the modifications addressed in plan are currently under construction and the system as a whole will not be operational until The construction projects will provide for the initial flush from the SIFM to go directly to the secondary treatment process to be held until capacity is available. The figure below includes the process flow during wet weather. IV-33

36 Figure 4-2 Wet Weather Operational Plan will be refined as the CSO facilities in the LTCP are completed. Most notably, the Operational Plan that was provided will be updated during the two year period provided in by NDEQ to ensure compliance with the e. coli and total residual chlorine limits in the CSO permit for CSO 102. Also, the City will continue to evaluate and fine tune the plan and procedures throughout the compliance schedule to account for the additional treatment and storage facilities as they come on line. For instance, once the tunnel has been constructed the City will develop plans to utilize that infrastructure. The modest change from last Annual Report is that the Municipal Headworks is in service receiving flows from the Monroe Street Lift Station and the In-Plant Lift Station. The Monroe Street flow is not represented separately on the diagram. The additional operational changes correspond to the completion of the Schedule B2 improvements when a post primary disinfection system is in place which will be in In addition, modifications to the plant to be able to treat 64 MGD through secondary treatment, and 150 MGD through primary are complete. However, until the SIFM is complete, the maximum flow will not be achievable. G. Maximizing Treatment at the Existing POTW Treatment Facilities An evaluation of the feasibility of expanding wet weather treatment at both the MRWWTF and the PCWWTF is included in Section 3.0 of the LTCP CSO Control Alternatives Evaluation and also 2014 LTCP Update. Major projects are included in the LTCP during the next 5 years to maximize treatment of combined wastewater at the MRWWF. Expansion of the treatment capacity of the PCWWTF is scheduled after this permit term. The CSO NPDES Permit requires the City of Omaha to continue to evaluate opportunities to maximize treatment at the WWTFs as part of the adaptive management strategy for IV-34

37 implementation of the LTCP and provide a summary of any new approaches identified to maximize treatment of combined wastewater at the WWTFs in this Annual Report. No new approaches have been identified. Projects related to current strategy are discussed in more detail in the relative progress report in Attachment 4. Expansion of the treatment capacity of the PCWWTP has not been identified under the CSO program and falls under the NPDES permit for that facility. H. Implementation Schedule The original LTCP Section 7.0, Implementation Schedule, outlined an implementation schedule that complied with the October 1, 2024 deadline for completing the CSO projects. The 2011 Missouri River Flood constituted a force majeure event which impeded the City's efforts at design and construction and impacted the schedules of several projects. The deadline of October 1, 2027 was put into effect. Per the modified CSO NPDES Permit, 10/1/2014, Part VI. Compliance Schedule for Implementation of CSO Control Projects lists the construction and sewer separation projects that will be designed, constructed, or operationally completed during the current permit term and the compliance milestones. CSO NPDES Permit requires the City to include progress reports on implementation of the CSO projects in the Annual Report. During this permit reporting period, the City continued to implement projects and adhere to a compliance schedule. This Annual Report, Section V - Compliance Schedule, provides a status update on the implementation of the CSO Major and Sewer Separation projects. Attachment 4 contains an Annual Project Progress Report for each of the projects under a compliance schedule. The LTCP had identified 5 other projects as system reliability projects to address current and future system support. The implementation schedule is as necessary and when funding available. Two of these projects continued final design during this report year: Burt Izard Lift Station and Riverview Lift Station Improvements. These are not under a compliance schedule but are given a brief status in Section V. I. Post-Construction Compliance Monitoring Program An outline of a post-construction compliance monitoring program is included in Section 8 of the LTCP Monitoring Program and CSO Wet Weather Operations Plan plus a draft document Water Quality Monitoring/or the Implementation Monitoring Plan (IMP) was included with CSO NPDES permit application received March 29, The current CSO NPDES Permit requires: 1. Instream monitoring data shall be conducted that is consistent with the Implementation Monitoring Plan. The data for this monitoring shall be included in the Annual Report. 2. Verification of sewer separation projects will be used to confirm that the desired level of separation was achieved. The City of Omaha may use various approaches to verify sewer separation including visual verification, water quality monitoring, or flow monitoring. The results of studies performed that support the deactivation of a CSO outfall are included in this Annual Report in Section VIII - Performance Report. IV-35

39 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 NPDES Permit and the Complaint and Compliance Order by Consent -August 8, 2007, NDEQ Case No (or Consent Order) issued to the City of Omaha (amended May 30, 2012) as well as the status of the individual or component projects. The amended Consent Order changed the completion date from October 1, 2024 to October 1, 2027 and required an update to the LTCP to be submitted to the NDEQ by October 1, The City has corresponded regularly with the NDEQ regarding any potential changes to the schedule. The CSO NPDES Permit set compliance schedules for this permit cycle based on LTCP Update schedule and subsequent schedule approval with NDEQ. A. Implementation Requirements The requirements for implementation are set forth in the CSO NPDES Permit as well as the Consent Order. Details with regard to each are presented in this Section. The CSO NPDES Permit specifically states: the City of Omaha shall implement the compliance schedule [as listed in the Permit] 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. These requirements are achieved though the summary tables and figures in this section as well as through the Annual Project Progress Reports in Attachment 4. As stated in the CSO NPDES Permit, the following definitions shall apply to compliance schedule dates. The italicized wording has been added in this Annual Report to provide additional clarification: 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 for bid. This compliance action 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. In some projects, an amendment to the original contract for Preliminary Design will serve as the date the Final Design began. Commence Construction The date the Notice to Proceed is issued to the contractor. Complete Construction When a major project or sewer separation project is substantially complete. For Sewer Separation as well as Major Facility Projects, substantial completion is issued to the construction contractor. In addition, notification is provided to the when a Major Facility Project is considered Operationally 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. NPDES Permit Modification and LTCP Update No Permit modifications were issued this report year. The modifications were submitted for the 2014 LTCP Update shortly after it was submitted; however the changes with regard to project names and milestone dates are reflected in the current CSO NPDES Permit. V-37

40 Consent Order Directives In addition to the current NPDES Permit, implementation and reporting requirements for this Annual Report are also guided by the Consent Order, which states the report shall contain: 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. These directives are achieved through the submittal of the Annual Project Progress Reports in Attachment 4. In addition, planned or expected deviations are tracked through an internal CSO Program process to document variations in schedule, scope, or budget. The Change Notifications Requests (CNRs) process includes identifying the reason or justification for a schedule change, potential impacts to related projects or LTCP Phases, and possible mitigation efforts. Any resulting CNRs have supported the LTCP Update process to date. Current CNRs for the reporting year can be found in Attachment 5. B. Major CSO Control Projects The implementation of the Major CSO Control Projects continued in the reporting year. The following summary tables are formatted to align with tables in Section 7 of the LTCP. Major CSO control Projects in Phase 1 through Phase 3 are listed in Tables 5-1 through 5-4. These tables cite the action or activity that took place during the reporting period, the LTCP target date for a particular action, the actual date if achieved, and a brief summary on compliance with the LTCP schedule. All completed component projects will continue to be included in the Annual Report until the particular Phase is completely achieved. Phase 4 of the Major Projects have no required activity to report this period. See LTCP Update for list of those projects and planned schedules. Table 5-5 lists system reliability projects which have had activity however are not under a compliance schedule. V-38

47 D. 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. The Annual Project Progress reports provide summary information regarding this objective in Attachment 4. This section addresses the overall status of the LTCP implementation. Schedule The schedule for the overall program takes a look at phasing and future financial planning to achieve the goals of the LTCP. Adaptive Management of the LTCP allows for the implementation of lessons learned and the adjustment of scheduling of the projects in the LTCP, with the concurrence and approval of the NDEQ. The City has communicated and will continue to communicate any potential impacts it may have to the scheduling and completion of projects to the NDEQ. Anticipated schedules have been reported in the APPRs for each active project. At the time of writing this report, certain schedules are undergoing review, Table 5-10 provides a look ahead at the overall status of the LTCP Phases with respect to their planned and adjusted milestones per next CSO Permit cycle. LTCP Update-Phase 3A is forecasted as having a delay due the reevaluation of Minne Lusa Conveyance system and related CSO projects. The projects associated with this system were placed on hold due to significantly increased costs and reduced benefits compared with the original LTCP In 2017 the City will be performing a technical reassessment to of the Minne Lusa Basin. It is anticipated that a revised list of projects and schedule for the basin will be provided to NDEQ early in LTCP Update-Phase 2 is also forecasted for a delay due to a single bid being received the Saddle Creek RTB Project ($128 million) that was significantly higher than the Engineer s estimate. A value engineering review was done of the project, which confirmed that the likely cost of the project is at least $117 million, which is still high compared with the LTCP budget. The project is currently being reevaluated to identify a more cost effective solution for CSO 205. The City is working with the NDEQ to modify the plan for CSO 205, with the intent to make a decision on the path forward in early At that time a permit amendment to establish new dates for the controls at CSO 205 will be requested. Figure 5-1: Total LTCP Projects Graph Figure 5-1 shows the count of projects per the LTCP Update (with March 2015 modifications reflected). Figure 5-2 shows the general status of completed and inprogress projects relative to their stage of study, design, and construction. Figure 5-3 reflects compliance with the 47 projects listed in the current CSO NPDES Permit. V-45

Controlling costs is important to ensure that the program continues to be as affordable as possible for the ratepayers, as well as to allow the LTCP schedule to be maintained. The cost of the program has been revised based on updated assumptions of project costs (when these are available), and has been adjusted from the initial Figure 5-4: CSO Program Allocation program estimate of $ 1.66 billion in 2009 dollars to correspond to current dollars. The revised cost of the program is slightly over $2billion. Third quarter CSO Program Management, as of September 2016, reports $294 million paid out for construction activities with over $100 million of projects in design. As previously reported to NDEQ, funding is of concern as the result of costs associated with increased opinions of probable cost of Phase I Major CSO projects. These issues have been communicated to the NDEQ throughout the reporting year, any information on adjustments in the schedule and costs of the individual projects within the program are included in Attachments 4 - LTCP Annual Project Progress Reports, and Attachment 5 - Change Notifications Requests.

51 VI. CSO Outfall Monitoring Data The CSO NPDES Permit requires a summary of monitoring data from Outfall CSO 102 and Outfall CSO 205.Section VII of the report includes Figure 7-1, which shows the locations of the CSO outfalls, along with the in-stream monitoring locations. 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 complied with these requirements. There were 66 overflow events at CSO 102 from October 1, 2015 through September 30, Results from these events are reported on quarterly discharge monitoring reports. The data for CSO 102 has been summarized in Table 6-1. 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 mg/l, which is the analysis detection limit. The value reported for Polychlorinated Biphenyls is less than 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. Table 6-1: CSO 102 Monitoring Parameter Value Units Flow Rate 2.64 MGD Total Flow MG Duration of Discharge Hours Total Suspended Solids 216 mg/l Biochemical Oxygen Demand 136 mg/l Dieldrin < mg/l Polychlorinated Biphenyls <0.001 mg/l E. coli 1,505,288 # 100 ml ph min=7.02 max=8.38 SU B. CSO Discharge Monitoring at Select Outfalls The CSO NPDES Permit, Part III specifies Interim Requirements for the Monitoring of CSO Outfall 205, which will be effective on October 1, Monitoring of CSO outfalls 105, 106, 107, 108 and 202 is no longer a requirement of the current CSO NPDES Permit, as it was in past reporting periods. VI-49

52 VI-50

53 VII. In-Stream Monitoring Data The current NPDES Permit requires a summary of instream monitoring data consistent with the Implementation Monitoring Plan objectives to include monitoring station identification, stream identification, the list of parameters along with the monitoring results. It is important to note that although In-Stream Monitoring was included as part of the Draft- Implementation Monitoring Plan, March 2010, it also states in the plan Although not legally required by state or federal regulations, the City has included in-stream water quality monitoring as part of the water quality monitoring plan. An in-stream water quality monitoring network within portions of the Papillion Creek, its tributaries, and the Missouri River will provide water quality data that benefits both the CSO Program and the Stormwater Program. A permit modification was accepted by the NDEQ with regard to the City s MS4 NPDES Permit, April 5, 2016 that modified the Program Elements of the Storm Water Monitoring Plan. With that, the in-stream monitoring was removed from the plan, and alternate elements approved. A summary of in-stream monitoring data is reported below in this annual report. Figure 7-1 is a map showing the locations of the in-stream monitoring sites. A summary of the data is provided in the following two sections: City In-Stream Monitoring and USGS Sampling and Analysis. A. City In-Stream Monitoring The in-stream monitoring for this reporting year was performed by the City of Omaha Quality Control Division and the Sewer Maintenance Division. The objectives of the monitoring were two-fold: to meet requirements of CSO NPDES Permit and City s Municipal Separate Storm Sewer System (MS4) NPDES Permit. However, the MS4 Permit submitted a modification request in March of 2016, and was approved by NDEQ in April 2016 that eliminated an element of the Stormwater Monitoring Plan that included the in-stream monitoring. Sites PC1, LPC1, BPC4, were eliminated in the new MS4 permit and were not sampled this year. The CSO Program in-stream monitoring sites: MR 1, MR2, MR5, CC1, CC2, LPC3, and BPC3, were collected by Sewer Maintenance Division staff and analyzed through Midwest Laboratories Inc. in accordance with the Implementation Monitoring Plan. As stated in this plan, the frequency of sampling is as follows: The in-stream monitoring will be performed during the spring (March 1 to May 31), summer (June 1 to August 31) and fall (September 1 to November 30) seasons. The frequency of monitoring will be twice per season, one of which will be during wet weather. The results for the wet weather and dry weather sampling are summarized in Table 7-1. Sewer Maintenance Division was not able to collect samples for the Season 2 Wet period due to lack of rainfall during normal working hours. Note that any results known at the time of writing this report will be reported regardless of the CSO Annual Report period ending on September 30, The Missouri River Sites were also sampled by USGS during this report period and is described in more detail in the next section.

56 B. USGS Sampling and Analysis In July 2012, the City of Omaha requested the U.S. Geological Survey (USGS) Nebraska Water Science Center to implement a Missouri River water-quality monitoring program at selected points on the Missouri River near the Omaha metropolitan area. The agreement with the USGS was extended through to 2016, and it is anticipated that continuation of this program will be necessary in the future. This program is consistent with the Implementation Monitoring Plan. The scope for the USGS work includes the following key components: 1. Provide continuous stage and discharge records for the Missouri River at locations important to the pursuit of understanding the water quality in the river. 2. Provide monthly discrete water-quality sampling of selected compounds at locations important to the pursuit of understanding on water quality in the river. 3. Provide continuous monitoring of selected water-quality parameters at locations important to the pursuit of understanding the water quality in the river. These scope items are further described in the following paragraphs. 1. Provide continuous stage and discharge records for the Missouri River at locations important to the pursuit of understanding the water quality in the river. Continuous stage discharge is provided by the USGS for the Omaha area at the I-480 Bridge gauging station. Data from location at the I-480 bridge can be found at: 2. Provide monthly discrete water-quality sampling of selected compounds at locations important to the pursuit of understanding on water quality in the river. The four discrete sampling locations are: MR-5 MR-4 MR-CB MR-1 USGS Site Number: USGS Site Number: USGS Site Number: USGS Site Number: Missouri River at NP Dodge Park (above the City) Missouri River at Freedom Park (below the Airport) Missouri River near Council Bluffs, IA (below MRWWTP and above the confluence with Papillion Creek, North/East side of the river) Missouri River near La Platte (downstream of the PCWWTP and below the confluence with Papillion Creek but above the Platte River) VII-54

57 Field parameters monitored at these locations include stream discharge, ph, temperature, dissolved oxygen, specific conductance, turbidity, E. coli and total coliforms, TSS, total phosphorous, BOD 5-day, TKN, nitrogen, nitrate, ammonia nitrogen, and floating debris. The USGS indicates whether there were wet conditions in Omaha or upstream during the sampling event. With the exception of E. coli and total coliforms, samples are a composite of the cross section of the stream. Discrete sampling data was collected by USGS staff and was analyzed through Midwest Laboratories, Inc. and USGS Labs. Samples were collected from a boat, and are based on depth-integrated sampling procedures used by the USGS to obtain samples that represent a composite of the cross section of the Missouri River at the sampling location. In addition to monthly sampling, The City may request specific studies from the USGS as needed. An example is that the USGS is currently collecting samples from the bank that correspond to the four site locations where they are collecting discrete river samples, to see if a relationship can be developed between the bank cross sectional stream samples. Starting in 2015, the City asked the USGS to collect two additional discrete samples during the recreational season targeting wet weather events. The City also asked to USGS to code the samples to identify if weather conditions immediately prior or during sampling were dry upstream, wet upstream, dry locally, and/or wet locally. Discrete sampling locations as described above are shown on Figure Provide continuous monitoring of selected water-quality parameters at locations important to the pursuit of understanding the water quality in the river. USGS obtains continuous data for the Missouri River at the following sites for ph, temperature, dissolved oxygen, specific conductance, and turbidity. All data is provided to the City directly as well as published on the USGS website for the sampling site. Data for MR-5 may be found at: Data for MR-CB can be found at: Data for MR-1 can be found at: Refer Figure 7-1 at the beginning of Section VII for the Missouri River continuous monitoring locations. Results from this effort will provide the City of Omaha with information to support long-term planning goals and regulatory compliance. The data from this study could be used to study temporal trends and evaluate water-quality variations during different discharge conditions. This study reinforces the goals of the USGS science direction by providing citizens, communities, natural-resources managers, and policymakers with clearer knowledge of the status of the Missouri River, an increased capacity to discover trends over time, and an improved ability to make decisions about future strategies and policies.

59 VIII. Performance Report As stated in the CSO permit, Part VIII, Section E, the performance report consists of A) reporting the number of times each CSO outfall has an overflow and an evaluation as to whether the controls are achieving their design intent. B) Documentation needs to be provided that demonstrates that each CSO overflow occurrence was the result of a wet weather event. C) Once in the term of the permit, provide the percent by volume of the combined sewage collected in the CSS during precipitation events on a system-wide annual average basis that is eliminated or captured for treatment. A. 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 maintains records of CSO overflow events at a majority of the outfalls in the system. Due to access or safety considerations, the outfalls are not monitored at the discharge point to the receiving stream, but rather in an upstream diversion structure. The City maintains a block program also commonly referred to as CSO device checks. Under this program a block or device placed as a simple physical indicator that an overflow has occurred. A typical arrangement would be the placement of the indicator on the top of a weir wall in a CSO diversion structure. The occurrence of an overflow is indicated when the device is moved off of the weir wall in the downstream direction. City procedure is to inspect these designated CSO structures and devices after rain or snow melt events and make a record of the inspection in the bypass tracking database if there is evidence of an overflow. City procedures were revised to meet requirements of the new permit starting 10/01/2015. City personnel are dispatched within 24 hours of wet weather occurrences, including weekends and holidays, to meet current permit requirements. The inspections are performed and documented by the Sewer Maintenance Division with assistance from the Quality Control Division - Levee Maintenance crew. Routine preventative maintenance checks at the lift stations and control gates also allows for a check for occurrence of CSOs. The wastewater treatment plants are responsible to recording the number of occurrences for CSO 102 and 201. With the exception of CSO 102, all of the visual observations are logged into a single database maintained at Sewer Maintenance Division. During the report period City staff logged 2116 total inspections, with 1771 being post rain and snowmelt checks, and the remainder being pay-day checks or every 2 weeks for potential dry weather occurrences. A total of 1124 overflows were recorded for 23 of the CSO points that the City is able to check. Table 3-1 reflects the frequency of CSO discharges. VIII-57

60 Table 8-1: Wet Weather CSO Occurrences CSO Outfall CSO Frequency VIII-58 Water Quality Sample Required* Yes *** Not Req d at this time * As required by CSO NPDES Permit ***CSO 119 was not monitored for CSO frequency due to unsafe conditions B. Evaluation of Completed Controls The CSO NPDES Permit requires reporting annually as to whether the controls are achieving their design intent. When CSO Controls are completed as identified in the LTCP the City monitors the effectiveness of that control. CSO 102;119 -The South Omaha Industrial Area Sewer Separation (SOIASS), the South Omaha Industrial Area Lift Station (SOIALS), and the South Omaha Industrial Area Force Main and Gravity Sewer (SOIAFMGS) projects have been completed. The objective of these

61 projects was to eliminate the overflow of high strength waste streams occurring during wet weather periods less than or equal to the 10-year design storm to the City s combined sewer system. Currently, six (6) industrial facilities deliver high strength flows via the Packinghouse Expressway (PEX) sewer to the SOIALS where they are pumped to industrial primary treatment facilities at the Missouri River Wastewater Treatment Plant (MRWWTP). Since start up began in March of 2014, the new systems have been subjected to numerous wet weather events from the period of April through September. During this time, a total of 47 storm events occurred. Three (3) of these events resulted in flows that exceeded the design flow of 17.4 MGD upstream of the lift station. The City is facilitating a project to investigate for sources of excessive stormwater inflow from the upstream system including cattle cleaning operations, inlets, and sewer cross-connections to the PEX. During the report year, the City has performed flow monitoring to isolate area that may be high contributors of heavy inflow and infiltration. In addition, improved mapping of the contributing system is underway including understanding how the private properties connect. CSO th & Pierce. The only project identified to Control this CSO was completed in However, a few inlets are still connected and are planned to be included in Sewer Separation Project for CSO 212, part of Phase 5 and not schedule to begin until 2022 in the Long Term Control Plan. A weir was built in the 30 outfall pipe, and is monitored to evaluate effectiveness of current completed sewer separation. In the report year, the CSO overflowed eleven (11) times. CSO 211 discharged 27 times in the report period for 10/1/2012-9/30/2013. This shows a significant improvement. City will continue to monitor this CSO. CSO 103 Bridge Street Lift Station. The 36 th Street and McKinley sewer separation project was completed November A sanitary system evaluation survey began during this report year to identify additional sources of inflow and infiltration. A potential Lift Station upgrade or replacement will be evaluated for a future project. The objective of the LTCP is to deactivate this CSO outfall pending verification and additional monitoring. This CSO discharged only 3 times during the report period, which previously averaged about 11 overflows. The City will continue to monitor this site. C. Wet Weather CSO Occurrences The CSO NPDES Permit requires that documentation is provided in the Annual Report that demonstrates that each CSO overflow occurrence was the result of a wet weather event. CSO discharges that occurred during dry weather even are reported in section III. D. Prohibition of CSOs during Dry Weather. Documentation is provided in Attachment 9 - CSO Inspection Report. The report demonstrates that each CSO overflow occurrence was the result of a wet weather event. This report identifies the CSO outfall inspected, the date and time, and by who completed the inspection. It provides the reason for the overflow, whether an overflow occurred and if it was still occurring. Comments and the rainfall amount are noted. The depth of flow at CSO 205 is also recorded as per City procedure. VIII-59

62 Additionally City reviews available rain data during the year and compares to the results of the inspections. Missouri River Wastewater Treatment Plant is responsible for recording and reporting their wet weather discharges from CSO 102. There were 66 overflows at CSO 102. The City uses this accounting as an additional check for the other CSOs. If there is another CSO with a greater frequency, than at CSO 102, City staff will take a closer look at the data and perform quality assurances queries to confirm it occurred during a wet weather event. Part of procedure is to check against Eppley Airport rain data, which registered 161 days with precipitation, this includes days with only trace amounts. Of that, 66 of the recorded rain events were 0.09 inches or greater. This count matches up with the MRWWTP and the highest frequency of CSO occurrences at the other CSOs in 60. Due to the spatial variation of rain, the number of occurrences and amount of rain recorded at Eppley is only used as a starting point of reference. On dates where only trace amounts are recorded by Eppley, a comparison to our City maintained rain gauges in the CSO area is performed and corrections are made to the tracking database to more accurately represent rainfall totals. D. Percent by Volume Captured The CSO NPDES Permit requires that once in the term of the permit, provide the percent by volume of the combined sewage collected in the CSS during precipitation events on a systemwide annual average basis that is eliminated or captured for treatment. The percent by volume eliminated or captured will be determined in a future Annual report. This modeling and analysis was not completed during this permit term. VIII-60

63 IX. 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. T his year s report also includes information on the continued coordination efforts with the EPA, updated information on the Missouri River Flood of 2011 and its effects on the CSS, as well, 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. MRWWTP Bank Stabilization Project In the spring of 2013, a significant failure of the Missouri River bank adjacent to the MRWWTP, in close proximity to proposed upgrades to the MRWWTP required as a part of the CSO LTCP was discovered by Plant staff. Included with this was a failure of the structure at CSO 102. The failure is a result of the large amount of silts and sand that were deposited over very poor soils in this area, in conjunction with an inability of the area to drain by gravity to the river. The additional overburden on the very poor soils in the area has resulted in large shifts in the topography; Coordination with the USACE and discussion with former plant staff revealed significant prior concerns with the stability of the river bank adjacent to the river. A Project was kicked off this year to provide bank stabilization improvements at the Missouri River Wastewater Treatment Plant (MRWWTP). These improvements are needed in order to protect a portion of the existing MRWWTP and facilitate construction of additional improvements (OPW 52648, Missouri River Wastewater Treatment Plant Improvements Schedule B2: Chlorine Contact Basin and Primary Clarifier Odor control) which are being bid and constructed separately. Current project status is contractor is nearly complete and has installed 2223 columns as of the end of October. The contractor has experienced slower than expected productivity because the many of the predrilled columns could not be installed. The site experienced additional sloughing or bank collapse after an August rain event and substantial completion by the end of the year may be affected. B. NPDES Permit Compliance Inspection On September 13, 2016 NDEQ representatives conducted an inspection with regard to compliance with the CSO NPDES Permit. The first part of the inspection went over records, processes, and procedures. The 2 nd part of the inspection visited 3 LTCP Projects, in construction. The sites visited were MRWWTP Improvements, Schedule A1 and B1; South Interceptor Force Main-North Segment, and JCB and Miami Sewer Separation. The MRWWTP Bank Stabilization was also among the projects visited. NDEQ noted issues with pollution prevention and uncovered trash containers at MRWWTP and SIFM sites. NDEQ compiled a report of the inspection and submitted to the City on October 28, IX-61

64 NDEQ inspection report suggested documenting improvements and submitting them to the NDEQ. This Annual Report will serve as the response to the comments and suggestions. Attachment 6 is an excerpt from the 60 page NDEQ inspection report submitted to the City along with the City follow-up site inspections. The Construction Managers were onsite during the inspections and were made aware of the concerns with uncovered containers. The issues cited in the report were addressed by the City through CSO Program protocols which require regular inspections and noted action taken. The City requires the construction contractor to employ an Environmental Compliance Officer (ECO) who is directly responsible for compliance with the Stormwater Pollution Prevention Plan (SWPPP). The City Environmental Inspectors perform weekly and post-rain inspections for compliance with the SWPPP. The observations are documented and shared with the ECO and Construction Management. In addition, the CSO Program assigns a Compliance Coordinator who performs random checks for compliance. C. EPA Coordination Efforts The City of Omaha continued its partnerships with the EPA Office of Research and Development office in Cincinnati, OH (EPA ORD) and various officials from EPA Region 7. The construction of the demonstration facility at the City Of Omaha Sewer Maintenance Facility was completed in The facility is designed to capture and treat stormwater before it enters the Little Papillion Creek, and includes both pervious pavers and bio-retention. Equipment is installed to help understand the effectiveness of this facility. The monitoring is funded through 2018 by the EPA, and will be executed for the City initially by the USGS. D. Reduction in the Number of Overflow Events As CSO LTCP projects are implemented the number of overflow events will reduce. To date in the program, the City has performed work to eliminate the occurrence of CSO at three permitted outfalls: CSO 209, CSO 104, and CSO 113. Of the remaining 26 outfalls, the level of reduction in the number of overflow events will vary due to: the type of control that is being established for a given CSO point through the implementation of the LTCP; the point in time when the control of a CSO point will be fully implemented as a part of the LTCP; and the unpredictability and varied nature of wet weather that impacts the magnitude, volume, and duration of the overflows at a given CSO point. Two CSO outfalls have had project completed and have shown a reduction in number of CSO occurrences. CSO 211, 66 th and Pacific has shown a reduction by more than 50% when compared to the year prior to the sewer separation project completion. CSO 103, Bridge Street has reduced the frequency of overflows by more than 70%. The monitoring of the overflows will help the city track the progress of and understand the success of the CSO LTCP and its projects as they are being implemented. As more projects come on line, a system to report the compliance monitoring associated with the CSO program will be developed in cooperation with the NDEQ. IX-62

65 E. Reduction in the Number of CSO Outfalls During this report year there has been no reduction of CSO outfalls. Any outfalls being evaluated for future deactivation are in section VIII B. Evaluation of Completed Controls. F. Receiving Water Quality Previous annual reports have provided information about sampling at some of the CSO outfalls. The CSO NPDES Permit cycle no longer requires CSO outfall sampling at 105, 106, 107, 108, and 202. Figure 9-1 shows the expected reduction in E. coli resulting from the implementation of the LTCP, based on the 2014 LTCP Update. A significant reduction in E. coli load to the Missouri River occurred with the implementation of the SOIA Lift Station. Another major reduction will occur when the South Interceptor Force Main and Missouri River Wastewater Treatment Plant projects currently under construction are completed. Figure 9-1: E. coli Reduction over LTCP implementation IX-63

66 G. City of Omaha RNC Program The City continues a program, referred to as the RNC (renovation of combined sewers) Program. The goal of this program is to address basement backups from the combined sewers that occur during rain events. The primary function of this program is to provide a level of customer service for those connected to the City s CSS, and to protect human health. Historically, this has been accomplished using localized separation within the CSS. This program is managed separately from the CSO Program; however crossover of procedures, plans, standards, and guidance documents occurs between the two programs. These projects are also closely coordinated with the CSO Program Projects. These projects often complement the LTCP Sewer Separation Projects. Although the intent is not to achieve a reduction in the impacts of the CSS at the CSO outfalls, the projects are designed in a manner to ensure that they do not result in negative impacts downstream. If possible, they are designed in a manner that will help achieve the goals of the CSO program, including reduction in frequency, magnitude, and duration of overflows, and ultimately the improvement of water quality. The RNC project activity that occurred this report year includes the $5 million dollar 49th & Caldwell Area Sewer Separation, almost complete at the time of this report. An additional project in the 18 th and Fort Street area began Sewer System Evaluation Survey, Fall 2015, and continued with preliminary study and design in These projects will provide localized relief from sewer backups into basements by separating smaller neighborhoods in the combined sewer systems. H. Rate Information In June of 2009 the City adopted a rate ordinance that provided for significant annual rate increases for the years 2011 through In the fall of 2012, The City and the Chamber of Commerce worked with the business community to adopt a rate structure that kept the residential share of the cost static while more evenly spreading the costs across the industrial and commercial customers. The proposed revisions were adopted by the City Council and the new commercial/industrial rate structure went into effect in January In 2014, Mayor Jean Stothert and the City Council approved an ordinance that provided for rate increases from 2015 through The City is in the process of working with a consultant to review and update the sewer revenue rate model in anticipation for a future rate ordinance that will establish rates beyond Figure 9-2 includes information on sewer rates for a typical residential household, both Omaha and the national average. The figure indicates that rates in Omaha will approach and potentially surpass the national average over the next few years. IX-64

67 Figure 9-2: Average Residential Sewer Fee Increase $60.00 $50.00 $40.00 $30.00 $20.00 National Average Omaha $10.00 $0.00 The University of Cincinnati financial capability assessment for Omaha s wastewater enterprise fund, completed in May of 2013 and provided to the NDEQ, remains in consideration. One conclusion was that by the year 2018, the Omaha wastewater service area, as a whole, will be at a Medium Burden level. However, the report also notes that some Communities of Concern within the service already approach the High Burden threshold, and by the end of 2027 the entire service area may be near High Burden. The report recommends that the Omaha closely monitor costs associated with its long term control plan and to manage the overall Program approach, level of control and schedule. The report also recommends that Omaha work with NDEQ to ensure solutions that are financially and environmentally sustainable. The City has recently contracted with a consultant to revise and update its Affordability study. The updated study will include the anticipated costs outside of CSO. As mentioned previously in this report, with the adoption of the July 2014 rate ordinance, Omaha has clearly shown a continued commitment to the goals of the LTCP Update and is making a very significant investment to do so. The City is working with the NDEQ to establish a framework on how to address issues related to Affordability of the program, and how an Integrated Planning process would allow for the City to best plan how to continue to improve water quality without creating an unsustainable burden on area residents and businesses. I. Material Management During the 2016 reporting year, waste material including building demolition materials, railroad ties, asbestos and soil were taken to landfills in the area from construction of capital projects associated with the CSO Program. The City will monitor and track contaminated waste materials and soils and use this report to update the NDEQ Waste Management Division. Several projects commenced or continued construction in 2016, but only a few generating excess soil or waste material that required disposal in a landfill. These projects and the volume of soil IX-65

68 or waste material disposed are presented below in Table 8-1. With the exception of two projects, all of the soil and waste material were disposed of at the Pheasant Point Landfill, as noted below in Table 9-1. Of note, as part of the SIFM North Segment construction in the Lewis & Clark Landing, 15 tons of hazardous waste was disposed as D006 (cadmium) waste at the Waste Management s Emelle, Alabama Facility. This waste was primarily soil (15 tons) and the associated decontamination water generated from pressure washing the soil storage container (0.084 tons). Table 9-1: Volume of Waste Disposed during LTCP Projects LTCP Project OPW Number Material Taken to Landfill Material Taken to C&D Landfill (tons) Nicholas Street Phase II Gilmore Avenue Sewer Separation Phase 1 John Creighton Boulevard (JCB) & Miami Street Sewer Separation Phase 1 Missouri River WWTP Improvements River Bank Stabilization South Interceptor Force Main North Segment Pheasant Point: tons (soil) Hawkins: 11,752 (rock, soil, brick and wood) Pheasant Point: tons (soil) Pheasant Point: 29,193 tons Emelle: tons of D006 hazardous waste 0 As part of the design process, additional environmental and geotechnical investigations occurred on a variety of projects. All of the cuttings were disposed in accordance with all applicable rules and regulations. Additionally, to provide the Contractor with the necessary guidance and protocols to manage and dispose of soil and groundwater generated during the implementation of the City of Omaha Combined Sewer Overflow (CSO) Long Term Control Plan (LTCP) Program, the City collaborated with the NDEQ to develop an NDEQ approved Materials Management Plan for Soil and Groundwater for the CSO Program. This Plan was approved by the NDEQ in April of 2012 and amended in July of 2013 and is referenced in the Project Manual of the Construction Documents. IX-66

69 Attachment 1 O & M Procedure Updates and Revisions Summary The O & M procedures, as documented in the Sewer System Operation and Maintenance Manual for Sewer Maintenance Division (Brown & Caldwell, 2006), had the following updates: Call Out Procedure 2016 Standard Operating Procedure (SOP) for Reporting and Public Notification of Dry Weather Sewer Overflows and Bypasses Attachment 1

70 Attachment 1

71 M E M O R A N D U M DATE: TO: FROM: RE: Sewer Maintenance Personnel John Diederich and Mike Mertz After Hours Call-Out Procedure The following is the procedure for after hour's calls. On-call personnel. On-call personnel shall include a CMF I and one Semi-Skilled Laborer or Automotive Equipment Operator II. The Foreman I will take the initial call and determine the appropriate response. One SSKL/AEO II will be the Jet Truck operator and will respond to all calls requiring a jet truck on site. In the event another person is needed on the call, the On-call CMF shall contact them off of the voluntary extra list. The call-out Working Foreman shall contact the customer by phone immediately, identify the problem and if it is necessary to respond, attempt to be on site within 20 minutes of the call. First Response: After normal working hours of 7 am to 3:30 pm the main phones at the Sewer Maintenance Division will be transferred to the City Dispatcher from 3:30 pm to 10:45 pm Monday through Friday. At the end of the dispatchers shift the phones will be transferred to the On-call CMF I s cell phone. (In the event the Dispatcher is on leave, the phones will be transferred to the CMF I s cell at 3:30 pm) On Friday night this will be in effect until 7 am on Monday. The CMF I will take direct calls from the citizens that call the Sewer Maintenance Division main phone line ( ). Some citizens will call the Street Maintenance line, , and will reach the answering service. These calls will be forwarded to the on duty CMF I. The answering service call back number is The Working Foreman I shall receive the call from the City dispatcher/resident/ Ans. Service*. If the call comes through the dispatcher or service the CMF I shall immediately call the customer and get a complete detailed report of the problem. If he determines that it is a private sewer problem, he shall so inform the customer and that will end the call. He shall also check that the address is within the City limits. If it is not he shall call the customer and inform them of the proper SID contact person.

72 The Call-out Foreman I shall have an up to date laptop. He shall also have a cellular phone and a digital camera If the Working Foreman determines that the problem may be sewer related he should immediately go to the site. He shall check the sewer manholes and the customer s basement to determine if there is a sewer back up. The Working CMF I will assist in the Jetting operation at all times. Clearing the Blockage: A basket, shoe or rake must be placed in the downstream side of the downstream manhole so debris from the line does not go through the manhole and plug the next line section. Reel out five feet of hose and install rubber hose guide (tiger tail) on hose. Install penetrator jet nozzle with extension and lower into manhole flow line. Turn water pressure to 1200 psi and release hose reel. The hose should now travel up the line. The operating water pressure should be 1200 psi. This will be sufficient to open most blockages, but in some cases a higher pressure might be indicated. Do not operate the water pressure higher than 1800 psi. Jet to the stoppage using medium reel speed. Once stoppage is felt, pull back hose with reel. Then release reel lever to hit stoppage again. Repeat until nozzle goes through or breaks loose stoppage. If needed work nozzle back and forth through blockage at least three times to assure that blockage is loosened and removed. This further assures that nozzle will not simply go through blockage and pump water upstream of block. Once the blockage breaks loose, reduce the jetting pressure, stop hose reel and rewind jet hose back to the downstream manhole until the surcharge is relieved. If blockage is not removed, use the jet saw. Before using the jet saw, inspect the area of the blockage for signs of recent boring projects. The jet saw can be effective in pushing a large piece of debris out of the line. If the jet saw fails, use a 15 nozzle for more striking force or a culvert nozzle such as Little Thunder for more mass. Then clean the line as required. This can be accomplished by using a 15 nozzle. After jetting the line check the upstream manhole to make sure it is clean. Clean debris from the manhole as needed. The manholes downstream of the jetting manhole must be checked to make sure they are not backing up. Clean debris from any manhole where debris is observed.

73 Documenting the Backup: Check with the property owner and inspect the basement for damage. If there is any damage, complete the damage evaluation form on the back of the work order and take digital photos of entire basement to document damaged and undamaged areas. This is not intended to be the basis for paying a claim to the property owner; it allows the City Attorney s office to verify the accuracy of the claim and the degree of any damage. If the backup is due to a blockage in the city main: Explain the policy for cleanup with the property owner/tenant. Be thorough, explaining the differences between Option I and Option II. Explain the importance of sending build back bids directly to 6880 Q street and all other claim information to the City Clerk as outlined in the formal Damage Claim Letter. Have the property owner sign the triplicate form and give them a copy. Call Legacy if property owner/tenant chooses option I. Answer any questions property owner might have, keep answers brief and to the point. Do not indicate to property owner that they will be reimbursed for damages. Damage claim questions should be referred to the City Law Department with the claim letter. The work orders must be filled out at the time of the back up. It is extremely important to include: Manhole numbers, pipeline length, pipe size, addresses, street names, and property owner names are correct and included on the work order. Document the proper description and tasks in the work order. Inspection Request should not be used when documenting a Backup or Bypass-Overflow. Only use Complaint Backup for basement backups or Bypass-Overflow for overflowing manholes. If the backup is determined to be private, a work order is still required and use Complaint Backup as the description and Private as the task with comments written describing how it was determined to be a private issue. This assists in both review of the damage claim and evaluating the problem line for preventative, corrective maintenance and future sewer projects. Process the initial memorandum to the NDEQ (blue sheet) per Notification of Dry Weather CSO and Bypass SOP. All other types of calls should also be documented with a completed work order and photographs as needed. For other problems such as a missing manhole cover, the Working Foreman shall determine whether it is a City sewer manhole and notify the appropriate agency if it is not a City manhole.

74 In the event of a blockage the call-out crew shall make every attempt to open the line. The call-out crew shall obtain the permission of the CMF III or the Division Manager before leaving a line that is still plugged. The Working CMF can handle some calls, such as loose or missing covers or keys dropped in an inlet, without help from the crew. The Working CMF will order barricades if needed and cover all cave-ins and open manholes with wood and barricades before leaving the job site. If cave-in or manhole does not belong to the city, note this on the work order who is the responsible party. Notify the dispatcher if you know whom it belongs to. The call-out CMF can either send an , text detailing back-ups and water main breaks after filling out paper work or the following morning at 6:45 contact the Maintenance Supervisor to discuss the previous night s back-ups to include follow-up work needed. All completed work orders shall have: Proper description and tasks assigned to correct node or line segment information about the back-up including how you jetted from which manhole, if done with the flow, if there are drop pipes in manhole, Any pertinent information that follow-up personnel need to know, such as TV follow-up and PM dates, Document on a copy of the 1/8 section map with the house and line segment where the back up occurred being highlighted Give original work order to the Maintenance Supervisor with copies to clerical staff. Overtime slips and completed Call Log must be given to the Supervisor as soon as possible. The call-out Foreman shall record the time of the workers who do not go to a yard to punch in. Their time shall begin when they arrive on site and end when they leave the site. Normal After Hours Response The Working Foreman shall contact the SSKL/AEO on call if he needs to jet a line or if he needs other on-site help. The SSKL/AEO shall go directly to the closest sewer yard, pick up a jet truck and go to the site. The main responder shall have keys to the yard he is using. The main responder shall attempt to get to a maintenance shop within 20 minutes and be on site within 40 minutes of being notified. Support. If the Working Foreman determines that additional help is needed because of the severity of the problem, he shall call someone off of the secondary/storm call list,

75 which is voluntary unless it becomes necessary to mandatory in help. Notify the Maintenance CMF III the next working day to update the list. The call-out Working CMF will notify the secondary, which yard to respond to, and what equipment is needed. The support person shall attempt to get to a maintenance shop within 20 minutes and be on site within 40 minutes of being notified. In the event a jet/vac is need the foreman shall call an AEO II off of the separate AEO II Secondary/Storm call list. Wet Weather Responses Pre-Storm Preparation If weather forecasters are predicting heavy rain associated with Thunder Storm activity, exercise the following protocol: --On-call CMF will contact all other CMF I s and CMF III s by phone call, text or to ask for staff who are willing to be available to report during off hours --The CMF group will inform all staff members about the potential for heavy rain and ask them to contact the On-call CMF if they are willing to be available and respond after hours as needed --All Staff members who are able to respond after hours, need to contact the On-call CMF this includes CMF s --The On-call CMF will compile a list of the staff members who called him/her. Note: If the numbers of staff who call the On-call CMF is not sufficient to cover the predicted storm event that occurs, the secondary list will be called for volunteers top down by seniority and if needed employees will be mandatorily required to report per the contract guidelines. Storm Response The On-call CMF will handle calls generated by the storm event to the best of their ability. If needing additional storm response help, the On-call CMF should call the pregenerated list of on call volunteers. If the need exceeds the pre-generated list, the On-call CMF can choose one of two options. 1) He/she can go directly to Q street and switch the phones back to the front office, and call the CMF III and all CMF I s to assist with the calls. 2) He/she can call the CMF III and CMF I s to go to Q St and call in more help, take over the phones and start a Call Log. Either option the first CMF in the office will call down the Secondary/Storm List to mobilize available personnel. If not enough responders are found the CMF III or his appointed replacement shall then call the Secondary/Storm List to MANDATORY personnel to respond and calling from the bottom of the list going up. Documentation Storm Related Calls It is important that every complaint have a separate and completed work order (even if there is not an issue found during the response). Each work order shall be documented as a rain event work order. The work orders needs to be compared to the call list to make

76 sure we did not miss any complaints. It is also important to document evidence or lack of evidence of a surcharge (photograph). If a backup is related to surcharge due to storm water I&I this needs to be documented. Legacy will not be called if a backup is related to storm water surcharge and we should not sign an agreement with the homeowner. A standard claim letter should be given to the homeowner. If a backup is not related to the storm event, it is necessary to document it as a complaint backup, and in the notes put down not storm related and complete the paper work as normal. Legacy will be called if the backup is not related to a storm water surcharge and the policy form/ agreement should be filled out with the homeowner. If the line was jetted, you must document condition of the line and the home before and after jetting (in both cases). Document missing manhole covers and flooded streets with the proper asset number, what we did to resolve the issue and that it was storm water related. Call-out Assignment Responsibilities Each member of the crew is responsible to take calls when assigned or find a replacement. Employees on sick leave, or IOD are not eligible for overtime and are responsible for finding call-out replacements. If an illness or emergency arises and a working Foreman cannot respond to a call they are to notify the Maintenance CMF III or another working foreman to cover for them until the illness or emergency is over. Once someone has been notified the dispatcher shall be called and informed of any change and its duration. If the primary is ill or has an emergency they shall notify the call out working foreman of the situation and expected duration. The working foreman will then contact a secondary volunteer to cover and notify the dispatcher of the change. Call-out Trucks Must be maintained and kept in good working condition. Have a full tank of fuel and full tank of water at the end of every shift. The

N/A KSA S and STAFFING Staffing will consist of Public Works Division Managers, supervisors, and field personnel who together must possess the following KSA s: Knowledge of City of Omaha NPDES Permits for the Wastewater Treatment Plants and Combined Sewer System and the reporting requirements contained therein. Skill in preparing accurate and detailed reports, as well as carefully prepared statements for media distribution. Ability to evaluate situations and conditions and exercise good judgment in determining a course of action. Telephone Personal computer Fax machine EQUIPMENT TASK DESCRIPTION Reporting to the NDEQ, violations of the NPDES Permits regulating the Wastewater Treatment Plants and the CSOs: Any diversion from or bypass of the treatment facilities or CSOs that are prohibited. Dry weather overflows or spills to the CSS. Public Notification of bypasses or overflows containing pollutants in concentrations that may present a threat to human health or the environment, or are in a location that presents a threat to human health or the environment. 2

79 PROCEDURE - GENERAL Upon discovery of a potential violation, critical information needs to be reported to the Nebraska Department of Environmental Quality (NDEQ) Regional Office within 24 hours. Provide verbal notification (via telephone or message system) for bypasses that reach the Waters of the United States to City management and NDEQ. The Initial Notification, see Bypass Memorandum Form, must be made as soon as possible and submitted to Supervisors/Management to make decisions and carry out further portions of the procedure. Supervisors/Management will evaluate criteria and issue Public Notification for particular events that are likely to cause an adverse impact to public health or the environment. Additionally, a Follow-Up Report, in the form of a letter, citing final cause and corrective actions, needs to be mailed to the NDEQ Headquarters within 5 days of the event. PROCEDURE DETAILED 1. DISCOVERY: The City is made aware of an event, such as a sanitary sewer overflow (SSO, which includes basement backups), overflow in the Combined Sewer Service(CSS) area during dry weather, or an otherwise unscheduled bypass of treatment: A call is received by Sewer Maintenance Division dispatch typically from a citizen, utility company, plumber, contractor, or other City staff and a Work Order is issued to the correct response crew. Quality Control Division or Sewer Maintenance Division staff discovers an event during standard daily procedures and involves other response staff as needed. 2. DETAILS: Complete an Unscheduled Bypass Memorandum form (see Attachment 1). The employee(s) responding to or discovering the event must gather the required information, at a minimum, on the paper form. The paper form is a 2-sided document, generally printed on blue paper, with required information to be filled out on the front and guidance provided on the back. The electronic form is available, and can be saved locally on a desktop or laptop. It is encouraged that most of the critical information gets filled out while in the field. The template is on the City Network: P:\CSO\CSO_SSO\SOPs\Notif1_Unscheduled_Bypass_Memorandum.doc A completed form can also be generated through data entry into the Bypass Tracking.mdb for New Bypass/Excursion Report. Hit the Generate Report button for a neat and complete version of the form. If the responding crew is unable, untrained, or uncertain about this process, contact the Public Works Specialist and she can assist with the data entry. Instructions for authorized users to obtain a copy of the database are in Attachment 7. 3

80 3. CRITICALITY: If reaching waters of the United States*, immediate notification must be elevated to responsible City management ( such as Quality Control Division Manager, Sewer Maintenance Division Manager, Sewer Maintenance Foreman III) Attachment 3 lists the incumbent staff. Typically this will be the Manager or Supervisor whose staff had the lead role in responding to or eliminating the overflow/ bypass. In addition, call one of the following personnel to discuss the severity of the bypass/overflow and determine the need for public notice (Step 6). 1. Civil Engineer IV:Environmental Engineering Manager 2. Designee of the Environmental Services Manager 3. Environmental Services Manager *Bypasses or overflows that reach a municipal separate storm system will be considered as reaching waters of the State unless specifically contained and prevention or clean up measures performed. 4. INITIAL NOTIFICATION (Verbal): notification to NDEQ Field Office representative listed in Attachment 2 shall be made by the responding crew or management as decided in Step 3 for all prohibited bypasses or overflows reaching surface waters of the United States. If the NDEQ Field Office representative is not available, a voice mail message will satisfy the requirement. 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. Verbal notification of bypasses not reaching waters of the United States shall be at the discretion of the Division that discovers the bypass. 4

81 5. INITIAL NOTIFICATION (written): The Unscheduled Bypass Memorandum shall be sent to the NDEQ Field Office representative and circulated to appropriate City Staff as follows: Either or fax. If no phone call was warranted or made, the form shall serve as the Initial Notification to the NDEQ. Again, 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. The employee(s) who responded/discovered the event are responsible for making the Initial Notification unless told otherwise by a supervisor or manager. A copy of the completed Unscheduled Bypass Memorandum form should be forwarded to appropriate manager(s). Copy Environmental Services Manager and Civil Engineer IV:Environmental Engineering Manager for events that reached waters of the State. Copy either the Designee of the Environmental Services Manager or the Public Work Specialist for record keeping and the Follow-Up Report (Step 8) 6. PUBLIC NOTICE CRITERIA: 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. ISSUING A PUBLIC NOTICE: This will generally be determined by The Environmental Services Manager. In his or her absence this responsibility will pass to the Civil Engineer IV, QCD Manager, or the Division Manager whose staff has the lead role in eliminating the overflow or bypass or other responsible Designee of the Environmental Services Manager. This responsibility requires evaluating the need for and drafting any news release for notification to the public of an overflow or bypass event. 5

Other Items of Interest A value engineered cost proposal (VECP) was identified by the North Segment contractor to change the approach for tunneling from the Leavenworth Sewer Site to the Leavenworth Lift Station site. The contractor identified cost savings by extending the rock tunnel south, beneath the Union Pacific Railroad line and eliminating the soft-ground tunnel. This approach provided for approximately $500,000 in savings to the City and the elimination of a number of risks with the soft-ground tunneling approach. During tunneling of the rock tunnel from shaft #2 to shaft #1 an unexpected geological anomaly was encounter. Specifically the rock elevation dipped below the expected elevation leaving the upper portion of the rock tunneling machine in soil. A dewatering system was placed into operation in the fall of 2017 to lower the groundwater level and allow for continuation of operations. In early October, tunneling activities recommenced, but boulders were then encountered in the soil anomaly halting operations again. These differing conditions are of sufficient concern to the contractor that work stopped until a new manner of execution and or design could be implemented. The approach forward is under consideration by the City, design staff and the contractor. 3 OF 3

The RTB will provide an underground structure where combined sewage is stored during wet weather events and treated (grit and screenings removal, settling, chlorination, and dechlorination) before discharge. The RTB is being designed to accept a peak-hour flow rate of 315 mgd. While targeting a maximum flow of 315 mgd using a modulated gate, equipment and reaction time will likely allow flows of greater than 315 mgd to enter the basin for short periods of time. The sizing of the RTB will accommodate these higher flows to meet expected effluent disinfection limits. The completion of this facility will result in a significant reduction in the volume of partially treated CSO, total suspended solids (TSS), and E. coli bacteria entering Little Papillion Creek. Flows in excess of the facility capacity will be routed around the RTB and discharged into Little Papillion Creek.

City continued to work with the Project Team to develop alternatives that will provide compliance with the EPA CSO Control Policy at a more affordable cost. Contractor Follow-Up/Engagement Continued engagement with contractors towards bidding the future project. Omaha Bidding/Contracting Market Continued tracking of metropolitan area construction contracts to determine trends in bid results, labor availability, and avoid projects bidding at the same time. Pre-Qualification of Bidders Institued a process to pre-qualify general contractors for bidding. Alternative Delivery City is preparing policies to incorporate alternative delivery methods for use in future CSO projects. Changes in Basin controls through investigation of the Saddle Creek Basin Anticipated Project Activity for Next Period The City will be making a decision on how to move forward with this project. Complete evalution of the the basin controls, including consideration of a storage tank or RTB as the end-of-pipe control technology. Contract with the Project Team to design/redesign the facility. Changes from the LTCP In August of 2015, a single bid of $128.7 million was received for the Saddle Creek RTB. This bid was significantly higher than the Engineer s estimate of $91 million. The City rejected this bid, and worked with the NDEQ to modify the project s scheduled completion date in the City s CSO NPDES permit. This allowed for the additional time necessary to reevaluate the design of the project, and provided a more realistic schedule for contractors to complete the work. A value engineering effort was completed to find ways to reduce the cost of the project. As was communicated during the Quarterly Meetings to NDEQ, the result of this evaluation is that the recommended budget of the RTB as currently designed is $125 million. The City is working with the designer of the project, Wade Trim, to review the project and develop alternatives that will provide compliance with the EPA CSO Control Policy at a more affordable cost. At this point in time this project is on hold. It is anticipated that the City will determine the path forward on this project early in 2017 at which time an amended schedule will be provided for inclusion in the Permit and the LTCP. 2 OF 2

The tunnel is being designed to operate as a pressurized system and convey flows resulting from a 10-year, 24- hour storm event. Tunnel construction will commence from a portal constructed in the bluff located immediately west of the Storz West Basin and terminate at an exit shaft located on a former industrial property east of the Paxton Boulevard, 31st Avenue, and JCB intersection. Improvements to the existing Pershing/Storz Detention Basins will include construction of a concrete apron to prevent scour and erosion, modifications to the Pershing Detention Basin embankment to maximize storage for the increased flows, and a 1,800 foot long double box culvert to convey flows north from the collector sewer outlet to the Minne Lusa outfall channel for subsequent conveyance to the Missouri River. These projects will result in Combined Sewer Overflow (CSO) volume and flow rate reductions to the Missouri River. In addition, the Storz West and Pershing Detention Basins will provide water quality benefits for the stormwater prior to discharging to the river.

119 CITY OF OMAHA COMBINED SEWER OVERFLOWS NPDES PERMIT NO. NE ANNUAL REPORT Changes from the LTCP -ANNUAL PROJECT PROGRESS REPORT- OCTOBER 1, 2015 THROUGH SEPTEMBER 30, 2016 The City has made a decision to put the Minne Lusa Stormwater System Projects that were directly impacted by the Minne Lusa Stormwater Tunnel and Conveyance system on hold, pending a re-evaluation of the Minne Lusa Basin. This information has been previously discussed with the NDEQ prior to the May 12, 2016 meeting. This decision is based on a number of factors, including the following: The estimated cost of the Minne Lusa Stormwater Tunnel and Conveyance System Projects has grown to more than $100 million dollars, or more than double the inflation adjusted cost used in the planning level estimate developed during the 2009 LTCP. Because of the higher costs, the projects can no longer be justified based on the cost/benefits assumed for the LTCP. In addition, the number of sewer backups reported in the areas served by the project have been reduced by previous work in the project area, so the potential benefits provided by the project have also reduced. Operational and permitting issues, which were not realized until the final design of the project. The path forward for the Minne Lusa Basin is to complete a re-evaluation of the entire basin to determine the most cost effective way to reduce the volume of combined sewage that overflows at CSO 105. The City s intent is to look more closely at those alternatives that use existing City infrastructure, combining this with new gray and green controls as necessary to achieve compliance with the EPA CSO Control Policy. This work will be done during the next year. The results of this evaluation will be provided to NDEQ in early This project will no longer be tracked.

The project covers a 522-acre area bordered on the north by Brown Street, on the east by 52nd Street, on the south by Northwest Radial Highway and on the west by Cole Creek. This sewer separation project is in the first phase of construction within the Cole Creek CSO 204 Basin and includes construction of new sanitary sewers along 63 rd Street between Taylor and Spaulding Streets and in Benson Park north of the baseball fields. Construction started in early 2015, and substantial completion was reached on July 30, A study was conducted for the entire area contributing to CSO 204. The City determined early in the preliminary design that an increase in the peak discharge of stormwater to Cole Creek would not be allowed by the City. The design of the CSO 204 area was modified from the conceptual plan in the 2009 LTCP, which called for new storm sewers sized for the 10-year design storm, to a design that would address sewer backups and localized street flooding without increasing the peak stormwater runoff from the area. This new concept relies more on a reuse of existing combined sewers converted to storm sewers. This change in concept, along with a determination that a portion of the area contributing to CSO 204 was already separated, allowed for the work schedule to be modified to be accomplished in six phases of work instead of the nine phases included in the 2009 LTCP. The projects will reduce flows in the collection system and will reduce the size of the storage tank at CSO 204.

Changes from the LTCP The LTCP Update was submitted September of 2014 and approved January 23, The schedule may change from what was submitted due to the delays during design in order to do the re-evaluation of options for construction. Delay the other phases of work may extended the construction of phase 2 into This includes time for coordination of utility relocations in advance of the start of construction as well as anticipated ROW needs. Due to the size of this project and the intended use of trenchless construction for a major portion of the project, the construction duration is anticipated to be longer than two years, pushing construction into Since Sewer Separation Phase 4 Milestone met with Lake James to Fontenelle, no CSO Permit modification needed, however schedule changes will be reflected in next LTCP Update and Permit Application. Other Items of Interest This Phase 1 project includes a 15-inch diameter sanitary sewer to relocate and upsize the existing sanitary sewer along 63 rd Street between Spaulding Street and Taylor Street to provide additional sanitary sewer capacity. The Phase 1 project also includes approximately 164 LF of 21-inch diameter and 403 LF of 24-inch diameter sanitary sewer from Ames Street to the Benson Park grit chamber to provide additional sanitary sewer capacity in the downstream system.

After probing at another location across the tracks, 50 feet to the north of the original proposed location, a new alignment was established for this storm sewer and the Union Pacific crossing permit was re-submitted for approval. The approval was granted. Storm sewer and sanitary sewer construction progressed from Albright Park southwesterly toward the Gilmore Avenue/Harrison Street intersection. Side street sewer connections were also constructed, and roads and sidewalks were re-paved. Anticipated Project Activity for Next Period The 84-inch-diameter storm sewer crossing of the Union Pacific tracks is expected to be completed in late December The City of Bellevue s wastewater pump station near the Gilmore Avenue/Harrison Street intersection will be decommissioned as part of this project. Sanitary sewage that is currently being routed to the Papillion Creek Wastewater Treatment Plant via an existing force main will be re-routed to the northeast along Gilmore Avenue and treated at the Missouri River Wastewater Treatment Plant southeast of 10 th & L Streets. Substantial completion of the sewer separation project is projected for September A separate Gilmore Avenue Landscape Improvements project will commence during the 2017 construction season and provide additional seeding, trees, and wetland plantings in the Albright Park detention area and the Harrison Street/Gilmore Avenue detention area. Changes from the LTCP No changes. Other Items of Interest The construction project has progressed throughout the year, starting with sewer construction work at the lower elevation areas near Albright Park and continuing primarily along Gilmore Avenue to the southwest and Harrison Street. Sewers within interconnecting streets of Gilmore Avenue have also been constructed and residential streets have been re-paved. The City of Omaha entered into an interlocal agreement with the City of Bellevue to decommission an existing, ailing wastewater pump station owned by the City of Bellevue.

The schedule extensions are related directly to the design progression for the Riverview Lift Station. Negotiations are currently occurring between the City and Burlington Northern and Santa Fe Railway (BNSF) for purchase of property for the Riverview Lift Station. Siting of the lift station is required to allow for selection of the final alignement of the gravity sewer. In addition, additional investigations are occurring for the 600 liner foot tunnel beneath the main-line BNSF tracks to mitigate risks associated with microtunneling. Other Items of Interest The Martha to Riverview Lift Station Phase 2 sewer was initially intended to include the conveyance sewers from the Spring Street sewer south to Grover Street. The associated conveyance sewer from Grover Street to Riverview Avenue was identified to be included in the Riverview Lift Station project. Since both sewers would be best constructed by a contractor specializing in conveyance projects, these elements have been combined into the Phase 2 project. 2 OF 2

This bid was significantly higher than the Engineer s estimate of $91 million. The City rejected this bid, and worked with the NDEQ to modify the project s scheduled completion date in the City s CSO NPDES permit. This allowed for the additional time necessary to reevaluate the design of the project, and provided a more realistic schedule for contractors to complete the work. A value engineering effort was completed to identify opportunities to reduce the cost of the project. The result of this evaluation identified a recommended budget for the RTB, as currently designed, of $125 million. With the information from the value engineering study, the City has determined that the project, as was originally designed, is too expensive, and a lower-cost, re-configured facility to address the combined flows from CSO 205 in a more cost effective manner needs to be developed. The City is working with the designer of the project, Wade Trim, to review the project and develop alternatives that will provide compliance with the EPA CSO Control Policy at a more affordable cost.

153 TECHNICAL MEMORANDUM OMAHA CSO CONTROL PROGRAM Change Description and Justification TM OPW Saddle Creek th and Dupont Retention Treatment Basin (RTB) Introduction The purpose of this Technical Memorandum (TM) is to summarize a request for change to the schedule for the Saddle Creek th and Dupont RTB Project. The change description and justification was prepared by the Program Management Team (PMT) to document that the Project is on hold pending redesign. This change was initiated by the PMT based on the change in schedule, cost, and scope for the design an dconstruction of the Saddle Creek CSO th and Dupont Retention Treatment Basin (RTB). Approval is being requested for this change in schedule, scope and cost. Description of the Change The Long Term Control Plan (LTCP) schedule identified the completion of construction of the Saddle Creek CSO th and Dupont RTB project as September 30, As noted below, the City has put this project on hold. At this time, it is unclear if the 2020 date will be met as additional evaluation of the project is currently occurring. Until the reevaluation is completed, it is not possible to identify the probable design and construction schedule for the project. Justification In August of 2015, a single bid of $128.7 million was received for the Saddle Creek RTB. This bid was significantly higher than the Engineer s estimate of $91 million. The City rejected this bid, and received approval from NDEQ on August 28, 2015 to modify the project s scheduled completion date in the City s CSO NPDES permit. This allows for the additional time necessary to reevaluate the design of the project, and provides a more realistic schedule for contractors to complete the work. A value engineering effort was completed in April 2016 to find ways to reduce the cost of the project. The result of this evaluation recommended a budget of the RTB as currently designed is $125 million. With the information from the value engineering study, the City has determined that the project, as was originally designed, is too expensive for the water quality benefits provided. A lower-cost, re-configured facility to address the combined flows from CSO 205 in a more cost-effective manner needs to be developed. The City is working with the designer of the project, Wade Trim, to review the project and develop alternatives that will provide compliance with the EPA CSO Control Policy at a more affordable cost. OMAHA CSO CONTROL PROGRAM 3

154 In addition, significant redevelopment and planned development has resulted in changes upstream within the Saddle Creek Basin from what was evaluated during the development of the LTCP. The City intends to seek opportunities to work with developers and large property owners to cost effectively incorporate elements, such as green infrastructure, in their projects to reduce peak flows and volumes of combined sewage that need to be controlled at CSO 205. This is an important factor in the reevaluation of the Saddle Creek RTB and the amount of funding dedicated to the work at the outfall. Other items the City intends to evaluate in an attempt to meet the CSO Control Policy requirements, and the overall goals of the Clean Water Act related to the work at CSO 205 in the most cost effective manner include: Volume reduction in areas upstream within the Basin, through the use of Green Infrastructure and/or by reducing the impacts of impervious surfaces, Diversion or detention of stormwater within the Basin to reduce peak flows, The potential implementation of real time controls within the Basin to maximize the use of the existing infrastructure. Reducing the impacts of infiltration and inflow within the sanitary sewers that connect to the Little Papillion Interceptor. Additional Investment in a system of flow monitors along the Papillion Creek Interceptor System, both upstream of CSO 205, and downstream to the Papillion Creek WWTP. Evaluate options for additional sewer separation in the Basin. To help minimize the overall delays on the project, and to also find opportunities to reduce project costs, an Early Soils Removal project was created to remove over 100,000 cubic yards of excess material from the site. The selected contractor for this project was able to divert this material from the landfill and use it as beneficial fill for a development. The costs for removal of the fill material were half of the cost as initially bid as part of the overall RTB project. In addition, four months of construction duration was saved from the future project by contracting the Early Soils Project separately. Over the next year the City and PMT will work to refine the path forward on this project. OMAHA CSO CONTROL PROGRAM 4

The following projects are included in this CNR. OPW Minne Lusa Stormwater Conveyance Sewer - 31 st Avenue and Paxton Tunnel OPW Minne Lusa Stormwater Conveyance Sewer - Storz West/Pershing Detention Basin Grading and Improvements OPW Minne Lusa Stormwater Conveyance Sewer Pershing Detention Basin to Minne Lusa Outfall Channel 41 st and Sprague St NW Sewer Separation Phases 1 and 2 41 st and Sprague St SE Sewer Separation Phases 1 and 2 46 th and Grand Street East Sewer Separation 43 rd and Boyd Street Sewer Separation Paxton Boulevard Stormwater Conveyance Sewer 30 th to 40 th Street OMAHA CSO CONTROL PROGRAM 1

156 Paxton Boulevard Stormwater Conveyance Sewer 41 st to 49 th Street Paxton Corridor Sewer Separation John Creighton Boulevard (JCB) Stormwater Conveyance Sewer The changes in the scope, schedule and costs are generally a result of a combination of design refinements to the Minne Lusa Stormwater Conveyance Sewer projects (31 st Avenue and Paxton Tunnel, Storz West/Pershing Detention Basin Grading and Improvements, and Pershing Detention Basin to Minne Lusa Outfall Channel). In particular, the Storz West/Pershing Detention Basin Grading and Improvements required design enhancements to meet the High Hazard Dam design criteria of the Nebraska Department of Natural Resources (NDNR), as well as other factors. The stormwater basin was not originally envisioned to be a high-hazard dam, but hydraulic evaluations necessitated storing more water at a higher elevation to allow for conveyance to the river during higher river stages. Therefore, in early 2016, the City of Omaha made a decision to put the Minne Lusa Stormwater System Projects that were directly impacted by the Minne Lusa Stormwater Tunnel and Conveyance system on hold, pending a reevaluation of the entire Minne Lusa Basin. The costs for the Mine Lusa Stormwater Tunnel and Conveyance System project escalated significantly because of the NDNR requirements, in addition, the benefits for sewer backups into basements was reduced, given the number of reported occurrences have subsided. The Minne Lusa Stormwater Conveyance Sewer projects were placed on-hold previously during 60% to re-evaluate the costs and effectiveness, which resulted in changes to projects upstream in the basin, which were incorporated into the 2014 LTCP Update.

157 TECHNICAL MEMORANDUM OMAHA CSO CONTROL PROGRAM Change Description and Justification TM Minne Lusa Stormwater Conveyance Sewer and Associated Minne Lusa Basin Projects Introduction The purpose of this TM is to summarize a request for change to the Long Term Control Plan (LTCP) for the Minne Lusa Stormwater Conveyance Sewer (OPW 52004) and associated Minne Lusa Basin projects. The change description and justification was prepared by the Program Management Team (PMT) to document the reasons for putting these projects on indefinite hold. Description of the Change The 2014 LTCP schedule identified for the Minne Lusa Stormwater Conveyance Sewer Project is shown in the table below. This project was divided into three construction packages; Pershing/Storz Pond to 31 & Paxton Tunnel (OPW 52004) Pershing Pond Outfall to Minne Lusa Channel (OPW 52752) Pershing/Storz Pond Grading and Improvements (OPW 52454) Minne Lusa Stormwater Conveyance Sewer Projects (OPW 52004, 52752, 52454) 2014 LTCP Schedule Complete Final Design February 9, 2016 Commence Construction OPW July 1, 2016 OPW June 1, 2016 Complete Construction July 1, 2020 Operationally Complete December 31, 2020 These LTCP dates are now invalid, as it is unknown if some or all of the projects will progress further in the form in which they are described in the LTCP. The current status of these projects is that; OPW was bid ready, OPW was at 100 percent and OPW was at 90 percent design. A previous CNR, Change Documentation Tracking Form Minne Lusa Stormwater Conveyance Sewer and Storz Detention Basin Improvements (Tunnel, Outfall Structures, and Basin), dated December 8, 2015 documents changes to the schedule and costs of these three projects from the 2009 LTCP. The changes in the OMAHA CSO CONTROL PROGRAM 3

158 construction cost estimates were generally a result of a combination of design refinements in general, and specifically from the design enhancements necessary to meet the High Hazard Dam design criteria of the NDNR, as well as other factors. The most recent available construction opinion of probably costs (OPCs) provided by the AECOM/URS design team are summarized below. Minne Lusa Stormwater Conveyance Sewer Project Pershing/Storz Pond to 31 & Paxton Tunnel (OPW 52004) * Pershing Pond Outfall to Minne Lusa Channel (OPW 52752) * Pershing/Storz Pond Grading and Improvements (OPW 52454) ** Construction Cost Estimate $73,689,000 (Bid ready OPC) $33,920,608 (100% Design OPC) $5,467,000 (90% Design OPC) Total $113,076,608 * In ENR CC dollars ** In April 2015 ENR CC 9992 dollars Because the projects listed above comprise the downstream stormwater conveyance system supporting several upstream sewer separation and stormwater conveyance projects and the downstream storage near the CSO 105 outfall, the following LTCP projects are also on hold until further notice. 41 st and Sprague St NW Sewer Separation Phases 1 and 2 41 st and Sprague St SE Sewer Separation Phases 1 and 2 46 th and Grand Street East Sewer Separation 43 rd and Boyd Street Sewer Separation Paxton Boulevard Stormwater Conveyance Sewer 30 th to 40 th Street Paxton Boulevard Stormwater Conveyance Sewer 41 st to 49 th Street Paxton Corridor Sewer Separation John Creighton Boulevard (JCB) Stormwater Conveyance Sewer Some of these projects have some conceptual design work completed, and some have not yet been initiated. All of these projects will be re-evaluated to determine if, how and when they will be moved forward into further design based on a combination of factors, including; The configuration and location of the downstream sewer system in the Minne Lusa Basin (either new or existing sewers), OMAHA CSO CONTROL PROGRAM 4

159 Evaluation of the need for these projects in their current form, another form, or not at all in relation to the effectiveness of already completed CSO Program LTCP projects throughout the Missouri River watershed, Individual project and overall CSO Program costs, and How these projects contribute to meeting the overall LTCP compliance requirements and CSO Program goals. Justification The projects listed above have been put on indefinite hold, this decision is based on a number of factors, including the following: The estimated cost of the Minne Lusa Stormwater Tunnel and Conveyance System Projects has grown to more than $100 million dollars, or more than double the inflation adjusted cost used in the planning level estimate developed during the 2009 LTCP. As a result of the higher costs, the projects can no longer be justified based on the cost/benefits assumed for the LTCP. The Stormwater Tunnel and the projects upstream that connected to the tunnel were originally planned to address basement backups and street flooding while achieving a reduction in CSO volume from an area that covered approximately 3 square miles of the 9 square mile Minne Lusa Basin. Starting in the early 1990s, efforts by the City to address numerous basement backups from this area through a series of partial sewer separation (local separation with the storm water released back into the combined system) have proven to be very successful in addressing many of these problems. The intent of the Stormwater Conveyance System Projects was to connect the localized areas of separation, add additional areas where reported backups and street flooding were still a concern, and convey the separated stormwater to the Missouri River. At the Planning level costs developed for the 2009 LTCP, this work was deemed to be a cost effective way to accomplish a reduction in CSO volume. The latest available revised costs for the work no longer justified the overall project benefits, which are lower than were previously assumed. The full impact of operational and permitting issues which were not realized until the final design phase of the project. As the final design of the project was coming together, the City s Operations staff expressed concerns related to the ability to operate control gates that were included in the project as a requirement of the City s flood control system. Permitting issues arose at the end of the design phase that included meeting competing and overlapping regulations and jurisdictions between US Army Corps of Engineers (USACE) Regulatory, USACE staff responsible for reviewing flood control, and the NDNR. The City needs time to realize the impacts of work completed to date or already committed to completing through construction, such as the Forest Lawn and Lake James to Fontenelle Park projects. At this time, the City has committed to approximately $90 million dollars of work within the Minne Lusa Basin. This includes projects that have already been completed, and projects currently under design that will be going to construction within the next year. The City needs a better understanding of the effectiveness of this work. The dollars invested by the City are based heavily on results of its InfoWorks computer model. OMAHA CSO CONTROL PROGRAM 5

160 Although confidence is high in the model, time to monitor and evaluate the impacts of the work as it is completed will provide real data that can be used to refine the InfoWorks model and better evaluate the controls necessary to meet the required CSO reductions for the Minne Lusa basin. The City is in the process of conducting a re-evaluation of CSO controls in the Minne Lusa Basin, as well as the overall Missouri River basin, to achieve the overall LTCP compliance requirements and CSO Program goals. Results of this re-evaluation will be documented in future Change Documentation. OMAHA CSO CONTROL PROGRAM 6

Original Plan: The 2009 LTCP identified the Gilmore Avenue Project as two phases of design and construction. Ohern/Monroe 119-6, Gilmore Avenue Phase 1 is part of the Sewer Separation Phase 3 and Ohern/Monroe Gilmore Avenue Phase 2 is part of the Sewer Separation Phase 5A as noted in Table 7-2 of the 2009 LTCP. Phase 2 final design was to be completed by the end of 2018 with construction complete by the end of Updated Plan: During design, the PMT and PT determined that both phases could be accomplished together in one construction package. The Project Team identified less storm sewer construction than originally planned in the conceptual stage and the complexity and existing alignment of the existing interceptor made it more cost effective to accomplish the construction in a single construction contract The combined project will provide sewer separation to an approximately 226-acre area in the Ohern/Monroe Basin and will consist of abandonment of some existing pipes, rehabilitation, and construction of new storm and sanitary sewers. The newly constructed and rehabilitated sewers will convey stormwater flow to the South Barrel and sanitary flows to the North Barrel. This separation will direct the overland creek flow entering the sewer system from Sarpy County to the South Barrel, which will convey stormwater to the Missouri River. The project incorporates green infrastructure (detention basin) that decreases the size of necessary downstream storm sewers and offers benefits to neighborhood residents. LTCP Update anticipated Construction to start in spring 2015, and substantial completion is expected to be reached by September The current anticipated schedule for the combined Gilmore Avenue Project (Phase 1 and 2 ) is to complete final design by mid-2015, begin construction in the Fall of 2015 and complete construction by the Fall of OMAHA CSO CONTROL PROGRAM 1

The Minne Lusa Stormwater Conveyance Sewer projects were placed on-hold at the 60 percent design stage to re-evaluate the costs and effectiveness, resulting in changes to projects upstream in the basin that were incorporated into the 2014 LTCP Update. Due to consideration by the City of alternatives in the overall Minne Lusa Basin, the start and completion of the Lake James to Fontenelle Park project Final Design, and the start and completion of Construction are delayed. Therefore, the Lake James to Fontenelle Park Final Design, Bidding and Construction Long Term Control Plan (LTCP) Completion dates will not be met. The Lake James to Fontenelle Project consists of two construction packages; OPW Fontenelle Park Lagoon Improvements OPW Paxton Basin Upstream Sewer Separation The LTCP schedule identified for the Final Design, Bidding and Construction of the Lake James to Fontenelle Park Sewer Separation Project is shown in the table below.
