The Metropolitan St. Louis Sewer District, No. 4:07-CV-1120 (E.D. Mo.) has been entered with an Effective Date of April 27, 2012. Under the Consent Decree, Metropolitan St. Louis Sewer District (MSD, District) agreed to make extensive improvements to its sewer systems to reduce pollution levels in urban rivers and streams. Over a 23-year period, MSD has committed to infrastructure improvement projects for work in the Sanitary and Combined collections systems and in the wastewater treatment plants with a total estimated cost of $4.7 billion in 2011 dollars. The objective of the improvement projects will be to eliminate and mitigate overflows of untreated raw sewage, priority being given to areas known to be problematic. MSD prepared this Sanitary Sewer Overflow Control Master Plan to comply with Paragraphs 23 through 30 of Consent Decree Case No. 4:07-CV-1120-CEJ. This Master Plan provides a collective summary of the remedial requirements (elimination projects) and remedial measures resulting from the analyses performed in the reports referenced below. Elimination projects will result in the elimination of all Constructed Sanitary Sewer Overflow (SSO) Outfalls. The Master Plan provides a conceptual scope and cost estimate for each elimination project. Remedial measures are the activities that will provide for adequate capacity in the Sanitary Sewer System to address known SSOs and Building Backups, as well as eliminate unpermitted bypassing at Sanitary Sewer System Wastewater Treatment Facilities (WWTFs), including Missouri River, Coldwater Creek, Lower Meramec, Grand Glaize, and Fenton WWTFs. Sewer System Evaluation Survey (SSES) This Master Plan includes (by reference) 21 SSES reports for the following watersheds/subareas:  Maline Creek  Spanish Lake  Watkins Creek  Bissell Point Subareas  Coldwater Creek  Deer Creek  Gravois Creek  Mackenzie Creek  Martigney Creek  University City  Fenton Creek  Fishpot Creek  Kiefer Creek  Grand Glaize Creek  Mattese Creek  Lower Meramec Subareas  Bonfils  Caulks Creek  Creve Coeur Creek  Fee Fee Creek  Missouri River Subareas The SSES reports comply with Paragraphs 14 through 18 of the Consent Decree. Metropolitan St. Louis Sewer District SSO Control Master Plan EXECUTIVE SUMMARY Page ES-2 December 31, 2013 Updated August 29, 2014 Hydraulic Model This Master Plan also includes (by reference) five Hydraulic Model Development reports for the WWTF Service Areas listed below:  Bissell Point  Coldwater Creek  Lemay  Lower Meramec River  Missouri River The Hydraulic Model Development reports comply with Paragraphs 19 and 20 of the Consent Decree. Capacity Assurance Evaluation This Master Plan also includes (by reference) five Capacity Assurance Evaluation reports for Service Areas listed above. The Capacity Assurance Evaluation reports comply with Paragraphs 21 and 22 of the Consent Decree. Master Plan Development The elimination projects and remedial measures outlined in this Master Plan were developed based on the findings from the SSES, Hydraulic Model, and Capacity Assurance Evaluation reports. Conceptual project scopes of work were based on estimated future flows. Standard approaches in the following categories were applied to elimination projects and remedial measures as part of MSD’s methodology in developing holistic solutions to Constructed SSO Outfalls, known SSOs and Building Backups, unpermitted WWTF bypassing, and other capacity-related Sanitary Sewer System issues.  Cost Estimating  Prioritization  Sequencing  Project Activities  Project Activities Duration Development These analyses resulted in the formulation of a logically ordered plan of remedial measures and elimination projects to resolve problems or issues within the Sanitary Sewer System. The plan was utilized in establishing the Constructed SSO Outfall Elimination Schedule found in Appendix C of this report. Remedial Measures Estimated capital costs in June 2013 dollars for remedial measures (comprised of Sanitary relief, tunnel, storage facility, Pump Station/forcemain, I/I reduction, and WWTF projects) total to approximately $1.726 billion. Remedial Requirements (Elimination Projects) There are 149 Constructed SSO Outfalls to be removed by MSD. Eighty-seven conceptual elimination projects were identified to remove these Outfalls. These elimination projects were deemed to be remedial requirements pursuant to the Consent Decree. To develop the Metropolitan St. Louis Sewer District SSO Control Master Plan EXECUTIVE SUMMARY Page ES-3 December 31, 2013 Updated August 29, 2014 Constructed SSO Outfall Elimination Schedule, elimination project target dates were developed using Microsoft Project software, a nationally recognized program used to manage capital improvement plans. Each elimination project is comprised of a number of activities and each activity has a time component. The project activities, together with durations and relationships, were used to plan the elimination project target dates. The following four target dates were developed for each elimination project: 1. Initial Design 2. Commence Construction 3. Complete Construction 4. Placement in Service The target dates were utilized to establish the Constructed SSO Outfall Elimination Schedule, comprised of four, five-year groupings indicating anticipated elimination time periods for Constructed SSO Outfalls. A graphical summary of the results is shown below. The complete list of 87 elimination projects is presented in Appendix D. Estimated capital costs in June 2013 dollars for elimination projects total to approximately $336 million. Additional costs for associated remedial measures in sequence to the remedial requirements to eliminate the District’s 149 Constructed SSO Outfalls are estimated at $759 million, which is included in the previously mentioned remedial measures total capital costs. Summary  This Master Plan describes the results of the SSES, Hydraulic Model, and Capacity Assurance Evaluation as well as specific measures that will result in the elimination of all Constructed SSO Outfalls, known SSOs, and Building Backups and/or that are necessary to ensure that there is adequate capacity in the Sanitary Sewer System to collect, convey, and treat anticipated peak wet weather flows under current and projected future conditions, in accordance with the Consent Decree. 33% 54% 85% 95%100% 0% 20% 40% 60% 80% 100% 120% 2009‐2013 2014‐2018 2019‐2023 2024‐2028 2029‐2033% RemovedCumulative Percent Constructed SSO Outfall Removal per 5-Year Period Metropolitan St. Louis Sewer District SSO Control Master Plan EXECUTIVE SUMMARY Page ES-4 December 31, 2013 Updated August 29, 2014  Remedial measures to address capacity limitations within the Sanitary Sewer System and to eliminate unpermitted bypassing are also included.  A flow metering plan is outlined in Appendix A of the Master Plan. Flow meters will be installed on the Sanitary trunk sewers which convey major flow into the Combined Sewer System.  The Master Plan provides a schedule of specific projects for the elimination of all Constructed SSO Outfalls and the goal of eliminating all other known SSOs as expeditiously as possible. The schedule provides for elimination of 85% of the Constructed SSO Outfalls (based upon the May 5, 2009 bypass database, 12 Constructed SSO Outfalls subsequently discovered by MSD, and one reclassified as an interceptor to the Combined Sewer System), and the goal of eliminating all other known SSOs by December 31, 2023. Included in the 85% are 11 Constructed SSO Outfalls: BP-591; BP- 155; BP-170; BP-348; BP-349; BP-198; BP-443; BP-545; BP-008; BP-451; and BP-621 scheduled for elimination no later than December 31, 2023.  The Master Plan identifies project target dates for initial design, commence construction, complete construction, and placement in service for each elimination project. In proposing the timing and order of elimination projects, MSD set priorities among projects based upon potential for human health and environmental impact risks, frequencies of activation, estimated volumes, and technical engineering judgment.  MSD proposes that elimination of 15% of the Constructed SSO Outfalls be scheduled after December 31, 2023 but before December 31, 2033, based on technical need, including project sequencing, acquisition of property rights and other legal requirements, utility coordination and relocation of capital projects by other municipal entities, unknown soil or other conditions, natural unknown impediments, and other similar issues.  The Master Plan includes estimated capital, O&M (if applicable), and present value costs for each identified remedial measure and elimination project in June 2013 dollars.  The Constructed SSO Outfall Elimination Schedule is presented in Appendix C of this report in the format specified by EPA.  The total estimated capital cost in June 2013 dollars for both elimination projects and all remedial measures is presented below:  Remedial Requirements (Elimination Projects) $0.336 billion  Remedial Measures $1.726 billion  Total $2.062 billion Conditions of Approval The EPA has approved this Master Plan with certain conditions. Those conditions are outlined in Chapter 7 and Appendix E of this updated Master Plan. One of those conditions is an approved schedule, which is presented in Appendix F. Also contained in Chapter 7 is a section on progress reporting. The District will apprise the EPA of their progress in executing the Master Plan by doing the following:  If MSD determines the date by which a SSO will be eliminated as set forth in the “Elimination of Constructed SSO Outfall or Known SSO Condition (no later than)” Metropolitan St. Louis Sewer District SSO Control Master Plan EXECUTIVE SUMMARY Page ES-5 December 31, 2013 Updated August 29, 2014 column of the table titled “Projects to Eliminate Sanitary Sewer Overflows” needs to be modified, MSD will request a change pursuant to Paragraph 30 of the Consent Decree.  Except for changes to the Elimination Dates discussed in the first bullet, MSD will report on the progress of “Projects to Eliminate Sanitary Sewer Overflows” as part of the “Background Information on All Master Plan Projects” in the Consent Decree Annual Report.  MSD will report progress on the projects in the “Background Information on All Master Plan Projects” documents as part of the Consent Decree Annual Report, including describing the actions taken to ensure an SSO will not occur when it is determined that a project is not required. When appropriate, MSD may include information in its annual report related to changes to project names, and material changes to project scope. These changes do not require EPA approval.

Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 1. INTRODUCTION Page 1-1 December 31, 2013 1. INTRODUCTION 1.1 District Overview The Metropolitan St. Louis Sewer District (MSD) provides wastewater and stormwater service to approximately 1.3 million people in a 525-square-mile service area encompassing the independent City of St. Louis and most of St. Louis County. According to a National Association of Clean Water Agencies membership survey, the District has the fourth largest collection system in the United States based on miles of wastewater sewer infrastructure. Most of the District’s customers are served by Sanitary and Storm sewers. However, approximately 75 square miles of St. Louis City and adjoining St. Louis County are served by a Combined Sewer System. 1.1.1 Service Areas MSD’s jurisdictional area is divided into five major Wastewater Treatment Facility (WWTF) Service Areas as shown in Figure 1-1 (page 1-2): Bissell Point, Coldwater Creek, Lemay, Lower Meramec, and Missouri River. The Bissell Point and Lemay Service Areas contain both Sanitary and Combined Sewer Systems, while the District’s other service areas are served by Sanitary Sewer Systems. 1.1.2 Watersheds The District’s five Service Areas are further subdivided into 21 predominately Sanitary Sewer System watersheds as noted below:  Bissell Point Service Area  Maline Creek Watershed  Spanish Lake Watershed  Watkins Creek Watershed  Bissell Point Subareas  Coldwater Creek Service Area  Coldwater Creek Watershed  Lemay Service Area  Deer Creek Watershed  Gravois Creek Watershed  Mackenzie Creek Watershed  Martigney Creek Watershed  University City Watershed Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 1. INTRODUCTION Page 1-2 December 31, 2013 Figure 1-1 MSD Service Areas Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 1. INTRODUCTION Page 1-3 December 31, 2013  Lower Meramec Service Area  Fenton Creek Watershed  Fishpot Creek Watershed  Grand Glaize Creek Watershed  Kiefer Creek Watershed  Mattese Creek Watershed  Lower Meramec Subareas  Missouri River Service Area  Bonfils Watershed  Caulks Creek Watershed  Creve Coeur Creek Watershed  Fee Fee Creek Watershed  Missouri River Subareas MSD’s watersheds are diverse. Each watershed has unique features and challenges. Some contain Combined sewers along with Sanitary and Storm sewers, while others utilize only Sanitary and Storm sewers. Some have no Pump Stations while others have many. Slopes, geology and land use, as well as age, size, and construction materials of the sewers all combine to create watershed differences that required site specific considerations during planning and development of remedial measures and remedial requirements (elimination projects). The term “watershed” as used in this report denotes sewer service limits and not necessarily topographical drainage areas. Some of the Combined Sewer Systems in Bissell Point and Lemay are outside of the scope of this Sanitary Sewer System Overflow Control Master Plan (Master Plan). Further information on Combined sewers may be found in the District’s CSO Long Term Control Plan. 1.1.3 Gravity Sewers Overall, the District is responsible for operating and maintaining 9,578 miles of sewers:  3,028 miles of Stormwater sewers  4,744 miles of Sanitary sewers  1,806 miles of Combined sewers The sewer lengths are based on data as of October 2013 and in some cases are different than the lengths reported in the SSES reports due to the continued characterization of the MSD collection system. Sanitary sewers range in size from 6- to 96-inches in diameter. The majority of Sanitary sewers (over 90%) fall into the 8- to 12-inch diameter range. The most common construction materials are vitrified clay pipe, at 63% by length, and plastic pipe, at 28%. Other pipe materials include concrete and iron. Some sewers have cured-in-place pipe liners. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 1. INTRODUCTION Page 1-4 December 31, 2013 1.1.4 Pump Stations and Forcemains The District is responsible for operating and maintaining 218 Sanitary sewer Pump Stations (based on data from October 2013) and associated forcemains, ranging in size from 2- to 42- inches in diameter. 1.1.5 Wastewater Treatment Facilities Seven treatment facilities process an average of 350 million gallons per day (MGD) of sewage. Flow statistics are based on measured average daily flows to the treatment facilities for the 5-year period between 4/27/2007 and 4/27/2012.  Lemay Wastewater Treatment Facility The Lemay facility serves a 120 square-mile (sq-mi) area, including approximately 35 sq-mi of Combined sewer area.

SEWER SYSTEM EVALUATION SURVEY Page 2-1 December 31, 2013 2. SEWER SYSTEM EVALUATION SURVEY As listed in Section 1.2, a total of 21 SSES reports were developed, one for each watershed and adjacent subareas. MSD prepared the SSES reports to comply with Paragraphs 14 through 18 of Consent Decree Case No. 4:07-CV-1120-CEJ. The SSES reports are part of the Master Plan. The District’s SSES accomplished the following:  Identified study areas with excessive inflow and infiltration (I/I), which are causing and/or contributing to Sanitary sewer overflows and Building Backups  Identified and quantified sources of I/I within the study areas determined to have excessive I/I rates  Identified known SSOs within each watershed  Identified stormwater cross connections and unauthorized direct connections  Identified physical and/or structural conditions of pipes, manholes, and structures of the Sanitary Sewer System that contribute to SSOs and Building Backups  Identified the physical conditions and design constraints of forcemains and Pump Stations, including failure of individual pumps, lack of redundant pumps, and lack of alternate power sources that contribute to SSOs and Building Backups These objectives were accomplished through a comprehensive investigation program that included I/I investigations, closed circuit television (CCTV), flow monitoring, and rainfall monitoring. The investigations conducted through this program (as of May 27, 2012) included:  Smoke testing in 425 I/I Study Areas  CCTV investigation of 27,132 sewer reaches  Inspection of 80,996 manholes  Data collection from flow meters at 1,261 unique monitoring locations  Data collection from 114 rainfall monitor locations The summary of findings of the SSES includes:  Identification of the locations of 1,261 known SSOs and 7,382 Building Backups (between April 27, 2007 and April 27, 2012)  Identification of 179 Constructed SSO Outfalls (remaining as of April 27, 2012)  Identification of 34 Pump Stations without backup storage capacity or on-site backup power  Identification of 3,085 stormwater cross connections (indirect connections) and 38 unauthorized direct connections Data collected during SSES activities was used to:  Develop elimination projects and remedial measures described in this Sanitary Sewer Overflow Control Master Plan  Identify manholes and sewer pipes in need of repair/rehabilitation/replacement through the District’s Capacity, Management, Operations, and Maintenance (CMOM) program  Calibrate and verify the District’s hydraulic model of its Sanitary Sewer System  Support the development of the Capacity Assurance Evaluation  Support the District’s Private I/I Reduction program Refer to the individual SSES reports for specific details on the SSES program.

HYDRAULIC MODEL Page 3-1 December 31, 2013 3. HYDRAULIC MODEL As listed in Section 1.2, MSD prepared five Hydraulic Model Development reports, one for each service area. MSD developed and documented the hydraulic models to comply with Paragraphs 19 and 20 of Consent Decree Case No. 4:07-CV-1120-CEJ. The Hydraulic Model Development reports are part of the Master Plan. MSD developed and uses the hydraulic models to assess the hydraulic capacity of the Sanitary Sewer System and to identify appropriate elimination projects and remedial measures to address capacity and condition limitations identified in its Sanitary Sewer System, including impact of forcemains and Pump Stations. The hydraulic models simulate wastewater flows under both dry and wet weather conditions, generate hydraulic grade lines, and estimate hydraulic capacities. The model results include conceptual sizing of sewer improvements needed to convey predicted wastewater flows. MSD configured each model to accurately represent its Sanitary Sewer System in accordance with currently accepted engineering practices. The models include gravity sewers that are 12 inches in diameter or greater, gravity sewers up to all Constructed Sanitary Sewer Overflow Outfalls and gravity sewers up to all MSD Pump Stations and forcemains. The District developed models that represent the individual watersheds and subareas, which were used to characterize the Sanitary Sewer System. The total length of Sanitary sewers modeled represents over 800 miles, or approximately 17 percent of the overall Sanitary Sewer System. The Hydraulic Model Development reports document the extent of each model, software used, and calibration and verification results. The reports are comprehensive and define procedures used by MSD to configure the individual models to accurately represent the District’s Sanitary Sewer System. The hydraulic models are beneficial for identifying potential problem areas in the existing Sanitary Sewer System. Using models, a project’s I/I reduction effectiveness was estimated and subsequent relief projects identified as necessary. The models were also used to evaluate alternatives such as larger sewers, elimination of I/I sources, storage, or combinations of these project types. Models were then configured to include all planned elimination projects and remedial measures. Using the modeled future flows and a 5- year synthetic design storm, the models were used to predict capacity assurance. Where relief sewers were identified, the sewers were sized to convey flows with a 10-year synthetic design storm condition. MSD’s hydraulic modeling process achieved the following:  Computerized hydraulic models were tested and verified by MSD to provide accurate results.  Models were used to assess the hydraulic capacity of the Sanitary Sewer System and to identify appropriate elimination projects and remedial measures to address all capacity and condition limitations, including the impacts of forcemains and Pump Stations.  MSD continues to refine the models to provide a detailed understanding of the response of its Sanitary Sewer System to wet weather events and to evaluate proposed remedial measures and removal or reduction of I/I flow.

HYDRAULIC MODEL Page 3-2 December 31, 2013  Best efforts were used to configure the individual models to accurately represent MSD’s Sanitary Sewer System, including the impacts of forcemains and Pump Stations, in accordance with currently accepted engineering practices.  Models included sewers 12-inches in diameter and greater to the extent practical and sewers up to Constructed SSO Outfalls, and sewers up to District Pump Stations.  Models were configured using adequate, accurate, and sufficiently current physical data for the Sanitary Sewer System.  Models were calibrated using two data sets and verified with one additional independent event, including rainfall data, metered hydrographs and Sanitary Sewer System flow data, to the extent data were available and reliable, as outlined in section 6.2.2.2 of the United States Environmental Protection Agency (EPA) report, Computer Tools for Sanitary Sewer System Capacity Analysis and Planning, October 2007.  Documentation of the hydraulic model for each watershed included:  A description of the hydraulic model, including the brand name of modeling software and capabilities  Digitized map(s) and schematics that identify and characterize the portions of the Sanitary Sewer System included in the hydraulic model, including the individual gravity sewer reaches, Pump Stations, and forcemains  Identification of input parameters, constants, assumed values, and outputs  A summary of activities undertaken to configure, calibrate, and verify the hydraulic model Refer to the individual Hydraulic Model Development reports for specific details on the modeling process. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 4. CAPACITY ASSURANCE EVALUATION Page 4-1 December 31, 2013 4. CAPACITY ASSURANCE EVALUATION As listed in Section 1.2, MSD prepared five Capacity Assurance Evaluation reports, one for each wastewater service area. MSD developed the Capacity Assurance Evaluation reports to comply with Paragraphs 21 and 22 of Consent Decree Case No. 4:07-CV-1120-CEJ. The Capacity Assurance Evaluation reports are part of the Master Plan. The reports include existing and future flows for each watershed within the Sanitary Sewer System, including average and peak daily dry weather flows, and peak wet weather flows and peaking factors. The Capacity Assurance Evaluation reports assess the ability of existing and future Sanitary sewer infrastructure to convey predicted existing and future peak flows, respectively. Summaries of the number and length of sewer segments surcharged due to inadequate capacity or backwater conditions, and the number of structures the model estimates will overflow under each condition investigated are presented. The reports also assess the ability of the wastewater treatment facilities to provide full treatment, without unpermitted bypassing (for Coldwater, Grand Glaize, Fenton, Missouri River, and Lower Meramec WWTFs, or Sanitary facilities), for all Sanitary flow reaching the WWTF, and to discharge those flows in full compliance with MSD’s Missouri State Operating permits in effect at the time the Capacity Assurance Evaluation was conducted. WWTF operating permits will dictate for individual plants whether bypassing treatment processes is permissible for the facility, such as allowed for the Coldwater WWTF. For the Lemay and Bissell Point WWTFs, or Combined sewer facilities, where bypassing is permitted, future Sanitary flows are assessed and wet weather storage and/or abatement projects are analyzed to allow continued compliance with Missouri State Operating permits in effect at the time the Capacity Assurance Evaluation was conducted. If the Missouri State Operating permit for any facility is issued or modified to permit bypassing of any treatment process, this condition will be considered during the planning and design of remedial measures. Districtwide, the capacity evaluation of the Sanitary Sewer System indicated no dry weather capacity issues under both existing and future flow conditions. The information developed through the capacity assurance evaluation process was beneficial in corroborating the identification of problem areas within the existing Sanitary sewer model, when combined with other data, such as customer service requests and Constructed SSO Outfall monitoring reports. The final model runs incorporated planned projects and utilized estimated year 2035 flows, which demonstrated the effectiveness of the elimination projects and remedial measures planned for each Service Area. As detailed in each Service Area’s Capacity Assurance Evaluation report, in mid-2013 MSD received updated population forecasts by East-West Gateway Council of Governments that indicate lower population growth rates through the year 2040 compared to the earlier forecasts through 2030. This new data was provided too late to alter the capacity assurance analyses performed. Specific measures identified to resolve existing condition capacity issues are still conceptually sized using original future flows from a 10-year synthetic design storm and the earlier population projections. However, in cases where an existing conditions flow analysis does not indicate a need for a project, but the future conditions flow analysis does, MSD has decided not to create a new project based solely on the projected future flow associated with the obsolete and higher population projections. Instead, these locations will be monitored before Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 4. CAPACITY ASSURANCE EVALUATION Page 4-2 December 31, 2013 determining whether a capital project is needed. MSD has a number of control measures in place to manage the potential for increased future flows as further described in the Capacity Assurance Evaluation reports. The following requirements were met through MSD’s capacity assurance process in accordance with the Consent Decree:  Determined existing flows for each watershed within the Sanitary Sewer System.  Determined average and peak daily dry weather flow.  Determined peak wet weather flow and peaking factors.  Identified portions of the Sanitary Sewer System experiencing levels of excessive I/I that cause or contribute to SSOs, Building Backups, bypasses, and/or overloading of the WWTFs.  Identified estimated peak flow capacities of modeled portions of the Sanitary Sewer System with inadequate capacity to convey peak wet weather flows.  Identified nominal peak flow capacities of unmodeled portions of the Sanitary Sewer System suspected of having inadequate capacity to convey peak wet weather flows.  In the case of inadequate capacity for a 5-year synthetic design storm and where the sewer system is being replaced, the replacement sewer was designed to a 10-year synthetic design storm condition.  Identified any inadequate capacity in the WWTFs.  Accounted for projected population and flow rate growth through 2035.  Determined summaries of the number and length of sewer segments surcharged due to inadequate capacity or backwater conditions and the number of structures the model estimates will overflow (including Constructed SSO Outfalls) under each condition investigated.  Assessed existing and future capacity of the Sanitary Sewer System to ensure the ability to convey predicted peak flows.  Gave priority to the elimination of Constructed SSO Outfalls and known SSOs. Refer to the individual Capacity Assurance Evaluation reports for specific details on capacity evaluations. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 5. DEVELOPMENT OF THE SSO CONTROL MASTER PLAN Page 5-1 December 31, 2013 5. DEVELOPMENT OF THE SSO CONTROL MASTER PLAN 5.1 Introduction The remedial requirements (elimination projects) and remedial measures discussed in this Master Plan were developed based on the findings from the SSES, hydraulic modeling, and capacity assurance evaluations. Remedial requirements will result in the elimination of all Constructed Sanitary Sewer Overflow Outfalls. Remedial measures are the activities that will provide for adequate capacity in the Sanitary Sewer System to address known SSOs and Building Backups. These remedial measures include removal of I/I sources; increases in the capacities of sewer pipes, forcemains, and Pump Stations; and construction of wet weather storage or equalization basin facilities. In many cases, remedial measures may be completed prior to remedial requirements. Specific remedial measures are further described in the five Capacity Assurance Evaluation reports. A number of standard approaches were applied to develop the components required to meet the requirements of the Consent Decree. Standard approaches in the following categories were applied to remedial requirements and remedial measures as part of MSD’s methodology in developing holistic solutions to Constructed SSO Outfalls, known SSOs, Building Backups, unpermitted WWTF bypassing, and other capacity-related Sanitary Sewer System issues.  Cost Estimating  Prioritization  Sequencing  Project Activities  Project Activity Durations The planning goal was to arrive at a Constructed SSO Outfall Elimination Schedule, as defined in the Consent Decree, based on MSD’s historical knowledge and experience in delivering capital projects and sound engineering practices. 5.2 Development of Remedial Requirements and Remedial Measures The SSES data, Constructed SSO Outfall locations, existing service request records, and assessment of hydraulic capacities utilizing hydraulic models all provided valuable information regarding identification of remedial measures and remedial requirements. 5.2.1 Identification of Remedial Requirements and Remedial Measures MSD analyzed available information to formulate the remedial requirements and remedial measures that were necessary to resolve problems or issues within the Sanitary Sewer System. Typical types of remedial measures and remedial requirements include relief sewers, I/I reduction, storage tanks or tunnels, Pump Stations, and wastewater treatment facility enhancements. Scopes of work developed for remedial requirements and remedial measures are conceptual in nature, based on currently available information and are subject to change in the future when more detailed data is available during the preliminary or design phases. Current approximations of relief sewer lengths and diameters, storage volumes and types of storage facilities, extents of Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 5. DEVELOPMENT OF THE SSO CONTROL MASTER PLAN Page 5-2 December 31, 2013 I/I reduction, and other conceptual scope items are expected to be modified and finalized at the design study stage of detailed design. A number of projects are to be built in sequence. The effectiveness of a predecessor remedial measure will not be fully known without a period of post construction monitoring. Depending on preceding project effectiveness, some subsequent projects may not be necessary. Refer to the Capacity Assurance Evaluation reports for remedial measures, representing a significant body of work. 5.2.2 Cost Estimating A standardized cost estimating methodology was developed utilizing cost curves and historic unit pricing data collected by MSD. Costs were generally organized into the following components: construction (including contingencies), engineering, and land acquisition, if applicable. Costs are presented in June 2013 dollars with a corresponding Engineering News Record (ENR) Construction Cost Index of 9542.33. Present worth calculations are based on a 50-year period, at an annual rate of return of 5% and a constant inflation rate of 3%. In many cases where different projects were considered to solve a problem, life-cycle costs or present worth values were used to compare alternatives. Although not always the determining factor, projects with lower present worth values were weighted more heavily in deciding between alternatives. A triple-bottom-line approach was used, taking into account not only cost, but environmental and social aspects as well. 5.2.3 Prioritization In proposing the time and order of remedial measures and remedial requirements, the District set priorities in accordance with the Consent Decree based on:  Potential for human health and environment impact risk  Frequencies of activation  Estimated volumes  Technical engineering judgment A priority scoring system was developed that took into consideration potential for human health and environmental impact, frequency of activation, and estimated volumes. Technical engineering judgment was used where factors other than priority score (e.g., the need for downstream capacity before building an upstream relief sewer, acquisition of property rights, utility coordination and relocation, unknown soil or other conditions, natural unknown impediments, and other similar issues) dictated sequencing. The priority scoring system assigned benefit points to each project in the following four benefit categories:  Constructed SSO Outfall Elimination/Mitigation – Projects earned benefit points in this category if a Constructed SSO Outfall was expected to be eliminated as part of the elimination project, or if the remedial measure is required for the removal of a Constructed SSO Outfall in a subsequent elimination project. Each Constructed SSO Outfall was given a high, medium, or low elimination priority based on the number and duration of recorded overflow events. The higher the elimination priority, the more benefit points the elimination or remedial measure project received. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 5. DEVELOPMENT OF THE SSO CONTROL MASTER PLAN Page 5-3 December 31, 2013  Service Request/Complaint Resolution – Benefit points in this category were earned if the project provided an ultimate solution to customer service requests that indicated a potential hazard to human health or the environment.  Capacity, Management, Operation, and Maintenance/Asset Management Benefits – Benefit points in this category were added if the project addressed capacity limitations and reduced the need for maintenance of the Sanitary Sewer System including Pump Stations and forcemains.  Inflow/Infiltration Reduction – Benefit points in this category were earned if the project provided for the removal of I/I sources. The priority scoring system resulted in a ranking of projects from highest to lowest point totals. MSD considered priority scoring and other relevant information, such as the relationships between elimination projects and remedial measures, to determine logical sequencing. 5.2.4 Sequencing Sequencing remedial requirements (elimination projects) and remedial measures was an important step in the development of the SSO Control Master Plan. Sequencing was based on the priority ranking, physical sequencing/phasing constraints, and other considerations to determine a logical order of construction. Elimination projects and remedial measures may be independent or dependent on one or more related remedial measures. Pursuant to the Consent Decree, elimination means that projects will not increase the frequency or volume of discharges from an existing Constructed SSO Outfall, known SSO, or CSO. Typically, downstream trunk sewers should be upsized or rehabilitated before upstream branch sewers. Also, it is prudent to perform upstream I/I reduction before sizing and constructing downstream sewers. MSD provided a sequencing of projects for each respective watershed based on knowledge of relational dependencies and watershed goals. These sets of watershed remedial measures were further analyzed and sequenced on a service area basis for coordination of remedial measures within a service area. Finally, sets of sequenced service area projects were analyzed and developed into an ordered, Districtwide network of projects with defined relationships. 5.2.5 Project Activities The following project activities were used, as appropriate for each individual remedial requirement and remedial measure project, to develop the planned target dates:  Preliminary – Activities include development of a scope of work and cost estimate in sufficient detail for use in a request for proposal for engineering design services and for capital program budgeting.  Consultant Negotiation – Included are activities to procure a design consultant, including the preparation and issuance of requests for letters of interest or qualifications, evaluation of the responses, preparation and issuance of requests for proposals, evaluation of the responses, evaluation of consultant interviews and selection of a consultant, fee negotiation, the introduction and adoption of the necessary ordinances to authorize MSD to enter into a contract for engineering design services, preparation and execution of contract documents, and confirmation of consultant insurance.  Pre-Design – Activities include the additional definition needed for making final planning- stage decisions. Also included are activities to conduct initial geologic and geotechnical investigations, initial hydraulic studies and models, initial right-of-way studies and surveys, Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 5. DEVELOPMENT OF THE SSO CONTROL MASTER PLAN Page 5-4 December 31, 2013 the development of schematic layouts, sketches and preliminary design criteria, and the development, review and approval of a pre-design report.  Initial Design – This start milestone activity denotes initiation of the detailed design phase.  Design – Activities consist of the detailed design phase, including final geotechnical and hydraulic studies, selection of final alignments, establishment of final design criteria, and the development of contract documents (plans and specifications).  Easement/Right of Entry – Activities include the acquisition of permits and approvals as well as the acquisition, through negotiation or condemnation proceedings, of the rights-of- way needed for construction. The easement activity also includes tasks related to obtaining property entry rights for identification of private inflow sources.  Property Acquisition – Activities include the purchase of real property, including property research, survey, environmental assessment, appraisal, price negotiation, the introduction and adoption of the necessary ordinances to authorize MSD to enter into a contract to purchase land, and execution of the deeds.  Bid/Board Approval – Activities include the advertisement for bids, bidding period, evaluation of bids and selection of a contractor, the introduction and adoption of the necessary ordinances to authorize MSD to enter into a construction contract, preparation and execution of contract documents, and confirmation of contractor insurance.  Commence Construction – This milestone activity denotes the construction start following Notice to Proceed issued to the construction contractor.  Construction – These activities include the construction phase in accordance with the contract documents and changes to the documents necessitated by differing field conditions, and oversight of the construction to ensure that the work conforms to the contract requirements.  Complete Construction – This milestone activity denotes field completion of the construction scope.  Start Up/Commissioning – Activities include testing of the various components of the work to verify that they perform as required, startup of the facilities to verify that components perform properly as systems, and final commissioning.  Post Construction Monitor – Activities include field monitoring activities and associated data analysis to assess the effectiveness of the remedial measures in meeting design and performance objectives for use in making decisions on subsequent improvement requirements. Field work may include standard SSES investigation techniques such as flow monitoring, smoke testing, CCTV inspection, and hydraulic modeling.  Placement In Service – This milestone activity denotes placement of the capital improvement into service; the exact definition varies by project type. For WWTF projects placement in service occurs after a start up/commissioning period. This holds true for large complex projects, such as major Pump Stations and storage tanks and tunnels. For typical Sanitary relief projects, placement in service coincides with complete construction. For typical I/I reduction projects, complete construction is followed by a one-year period of post construction monitoring then placement in service.  Constructed SSO Removal – This milestone activity captures the date a Constructed SSO Outfall is removed from service as documented by an MSD Overflow Modification form. Remedial requirements (elimination projects) and remedial measures may not include all of the activities listed above. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 5. DEVELOPMENT OF THE SSO CONTROL MASTER PLAN Page 5-5 December 31, 2013 5.2.6 Project Activity Durations The time necessary to complete an activity varies depending on the specifics of the remedial requirement and remedial measure. The District drew upon its extensive history in project delivery to arrive at the following typical durations for each identified activity:  Preliminary – Typical duration for Preliminary Studies is 6 months.  Consultant Negotiation – Typical duration for Consultant Negotiation is 9 months.  Pre-Design – Typical duration for Pre-Design is 12 months and is used only for major/large construction scopes.  Initial Design – This is an activity start milestone with zero duration.  Design – Typical durations for Design are 12 months for design fees up to $1 million and 18 months for design fees over $1 million.  Easement/Right of Entry – Typical duration for Easement Acquisition and/or property entry rights for identification of private inflow sources is 12 months. If applicable, the following durations were added to the base duration to account for project-specific circumstances known by the District which extends the time it takes to obtain easements:  Add 6 months if condemnation is required. Should easement negotiations fail, additional procedures are required to obtain easements through the condemnation process.  Add 6 months if there are more than 50 easements needed. The higher number of easements adds to the time required to prepare and secure the easements.  Property Acquisition – Typical duration for Property Acquisition is 12 months. If applicable, the following durations were added to the base duration to account for project- specific circumstances known by the District which extends the time it takes for property acquisition:  Add 6 months if condemnation is required. Should property negotiations fail, additional procedures are required to obtain property through the condemnation process.  Add 6 months if there is a need for asbestos abatement. Additional time is needed for testing, preparation of reports, reviews/permits, and asbestos removal.  Bid/Board Approval – Typical duration for the Bidding, Award, and Board Approval process is 6 months.  Commence Construction – This is an activity start milestone with zero duration.  Construction – Typical base durations for the Construction phase are 12 months for construction costs up to $2 million, 18 months for construction costs between $2 and $10 million, and 24 months for construction costs above $10 million. If applicable, the following durations were added to a base duration to account for project-specific circumstances known by the District which extends the time it takes for construction:  Add 3 months for work predominantly in Missouri Department of Transportation (MODOT) right-of way. MODOT has additional administrative procedures to follow, including coordination; reviews, inspections and approvals; and permit requirements which add to the construction duration.  Add 3 months for significant bypass pumping requirements. Additional time is required to set up bypass pumping around the work area. Production is also slowed by the necessity to work during low flow periods during the day. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 5. DEVELOPMENT OF THE SSO CONTROL MASTER PLAN Page 5-6 December 31, 2013  Add 6 months for work in predominantly residential areas. Additional time is required to implement extra safety measures, including traffic control, dust control, providing access to driveways, and temporary restoration. Public service requests are more prevalent and allowable work times are often restricted.  Add 6 months for work around major utilities. Crossing or paralleling major utilities or railroads requires additional measures to protect the integrity of the existing utility or railroad. Permits, plan reviews, and approvals add time. Diligence during construction to perform the work in a safe manner slows productivity.  Add 6 months for construction in the corporate limits of Maryland Heights and Chesterfield, and the Missouri River Subareas due to prevalence of poor soils. Poor soils slow construction production rates. Typically sheeting and shoring requirements are increased for safety and groundwater dewatering systems are required to further stabilize the soil during construction. In addition, testing requirements may be increased.  Add 6 months for construction south of Interstate 64 due to prevalence of shallow rock. Rock is more difficult to excavate and takes more time than normal soils in the area. Special ripping equipment and/or blasting may be required. Additional permitting may be required as well as limited working hours.  Add 3 months for construction with significant jack-and-bores. Jack and bores require excavation and protection of jacking and receiving pits. The pipe jacking process is significantly slower than conventional open cut construction methods.  Add 3 months for construction in known contaminated areas. Additional time is needed for regulatory coordination. Soil and groundwater testing may be needed as well as treatment and disposal requirements. These requirements slow standard production rates.  Complete Construction – This is an activity finish milestone with zero duration.  Start Up/Commissioning – Typical duration for Start Up and Commissioning is 4 months.  Post Construction Monitor – Typical duration for Post Construction Monitoring is 12 months. The duration of this activity is weather dependent. On average, 12 months would cover all four seasons and should be adequate to capture significant rain events for evaluation of I/I reduction effectiveness.  Placement In Service – This is an activity finish milestone with zero duration.  Constructed SSO Removal – This is an activity finish milestone with zero duration. The actual removal of the Constructed SSO Outfall is included as part of a construction project, or performed by MSD Operations. In situations where projects were developed beyond the conceptual stage where more information is known, the durations noted above have been modified to take into account specific project knowledge. Activity durations for large complex construction scopes, such as tunnels, were individually developed due to their unique nature. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 5. DEVELOPMENT OF THE SSO CONTROL MASTER PLAN Page 5-7 December 31, 2013 5.2.7 Costs for Remedial Measures Paragraph 28 of the Consent Decree requires the Master Plan to provide estimated capital, O&M (if applicable), and present value (or present worth) costs for remedial measures and elimination projects. Such costs shall be provided in consistent, year-specific dollars. Costs of remedial measures other than elimination projects are provided in Table 5-1, below. Subtotals are given for the types of remedial measure anticipated. Costs are in June 2013 dollars. Refer to the Capacity Assurance Evaluation reports for more information regarding the remedial measures. Table 5-1 Costs for Remedial Measures Category Capital Cost Present Worth O&M Sanitary Relief $306,686,000 $308,600,000 $1,914,000 Tunnel $573,663,000 $519,750,000 $30,521,000 Storage Facility $190,461,000 $200,705,000 $10,244,000 Pump Station /Forcemain $48,326,000 $59,506,000 $11,180,000 I/I Reduction $498,370,000 $591,785,000 $93,415,000 WWTF $108,000,000 $168,646,000 $60,646,000 Total $1,725,506,000 $1,848,992,000 $207,920,000 In cases where a remedial measure contained more than one category, the cost was assigned to the predominant component. I/I reduction includes both public and private components. The O&M costs shown above represent the current value of operation and maintenance costs for a 50-year period, which are calculated as the difference between the capital cost and present worth. For the tunnel category, the present worth is reduced by the remaining value of the tunnel at year 50, halfway to its 100-year life span. Elimination projects are discussed in the next section. Capital and present worth costs are presented for the projects that eliminate Constructed SSO Outfalls in Table D-1 in Appendix D.

Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 6. REMEDIAL REQUIREMENTS (ELIMINATION PROJECTS) Page 6-1 December 31, 2013 6. REMEDIAL REQUIREMENTS (ELIMINATION PROJECTS) 6.1 Introduction The development process previously discussed resulted in the remedial requirements (elimination projects) outlined in this Master Plan, which eliminate all Constructed SSO Outfalls. Elimination Project Target Dates, used to finalize the Constructed SSO Outfall Elimination Schedule, are presented in Appendix B. MSD’s May 5, 2009 “Bypass Database” spreadsheet identified 210 Constructed SSO Outfalls in the District’s jurisdictional area. Thirteen Constructed SSO Outfalls were subsequently discovered by MSD and one (BP-252) was reclassified as a diversion to the Combined Sewer System, resulting in 12 additional and 222 total Outfalls to be removed. Early elimination projects removed the 50 Constructed SSO Outfalls listed in Appendix B of the Consent Decree (as previously reported to EPA in MSD’s 2011 and 2012 Annual Reports). Other capital projects and, in some cases, work orders performed by MSD Operations, eliminated another 22 Constructed SSO Outfalls. Plus one more Constructed SSO Outfall was determined to be an interceptor (BP-477) and was reclassified as a mislabeled Constructed SSO Outfall. As of the date of this Master Plan, there are 149 remaining Constructed SSO Outfalls. This Master Plan outlines the timetable (in 5-year periods) for elimination of these remaining Constructed SSO Outfalls in Appendix C. 6.2 Remedial Requirement (Elimination Project) Target Dates Remedial Requirement (Elimination Project) Target Dates, presented in Appendix B, were developed using Microsoft Project software, a nationally recognized program used to manage capital improvement plans. Each elimination project is comprised of a number of activities and each activity has a duration, or time component, as described in Section 5. The project activities, together with durations and relationships, were used to plan the elimination project target dates and to develop the Constructed SSO Outfall Elimination Schedule, designated as Appendix C in the Consent Decree. The following four target dates are provided for each Elimination project: 1) Initial Design 2) Commence Construction 3) Complete Construction 4) Placement in Service Additionally, the identification numbers of the eliminated Constructed SSO Outfalls are provided. The preliminary target dates listed in Appendix B are for planning coordination only, used to develop the Constructed SSO Outfall Elimination Schedule in Appendix C, and are not to be used as a detailed schedule. Additionally, dates are subject to change based on Paragraph 30 of the Consent Decree, whereby MSD may request that a numbered Constructed SSO Outfall be rescheduled from the 5-year designated grouping in the approved Master Plan, Appendix C, to a later or earlier designated 5-year grouping, provided that the total cumulative number of Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 6. REMEDIAL REQUIREMENTS (ELIMINATION PROJECTS) Page 6-2 December 31, 2013 Constructed SSO Outfalls to be removed as of any date in the Master Plan Appendix C does not decrease. Dates could change due to various reasons, including but not limited to unforeseen conditions and unplanned events, such as project sequencing, acquisition of property rights and other legal requirements, utility coordination and relocation of capital projects by other municipal entities, unknown soils or other conditions, natural unknown impediments, and other similar issues. 6.2.1 Scheduling Constraints and Considerations A number of scheduling considerations were carefully examined to arrive at the proposed Elimination Project Target Dates. Consent Decree requirements were thoroughly reviewed and followed, including:  Elimination of at least 85% of the Constructed SSO Outfalls no later than December 31, 2023  The goal of eliminating all other known SSOs as expeditiously as possible  Elimination of eleven Constructed SSO Outfalls: BP-591, BP-155, BP-170, BP-348, BP-349, BP-198, BP-443, BP-545, BP-008, BP-451, and BP-621 by no later than December 31, 2023  Elimination of no more than 15% of the Constructed SSO Outfalls (excluding the eleven mentioned above) later than December 31, 2023, but only if based on a demonstration of technical need to delay the specific elimination projects. In no event shall the elimination projects be completed later than December 31, 2033. Technical need considerations include project sequencing, acquisition of property rights and other legal requirements, utility coordination and relocation of capital projects by other municipal entities, unknown soil or other conditions, natural unknown impediments, and other similar issues. Another consideration was integration of projects already included in MSD’s five-year Capital Improvement and Replacement Plan (CIRP). Many projects that are included in the SSO Control Master Plan are already in design or construction. These projects were deemed to be priorities for SSO Control Planning. The Consent Decree definition of eliminating a Constructed SSO Outfall requires that in no case shall the complete and permanent removal or permanent abandonment of a Constructed SSO Outfall be designed to create a new Constructed SSO Outfall, require the physical modification of an existing Constructed SSO Outfall, or increase the frequency or volume of discharges from an existing Constructed SSO Outfall, known SSO, or Combined Sewer Overflow (CSO). These conditions were carefully considered during elimination project and remedial measure sequencing and elimination scheduling. The Constructed SSO Outfall Elimination Schedule presented in Appendix C assumes that in cases when a post monitoring period is followed by an elimination project to remove a Constructed SSO Outfall, the Constructed SSO Outfall removal date is based on the completion of the last project in the sequence of planned projects. A number of projects are to be built in sequence. The effectiveness of a predecessor remedial measure will not be fully known without a period of post construction monitoring. Depending on preceding project effectiveness, some subsequent projects may not be necessary. Refer to the Capacity Assurance Evaluation reports for those remedial measures, representing a significant body of work. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 6. REMEDIAL REQUIREMENTS (ELIMINATION PROJECTS) Page 6-3 December 31, 2013 6.2.2 Master Plan Appendix C The Consent Decree includes a format to be used for the presentation of the schedule for Constructed SSO Outfall eliminations. The table included four, five-year groupings indicating the anticipated elimination time periods for Constructed SSO Outfalls. The Constructed SSO Outfall Elimination Schedule, Table C-1 (page C-1) in Appendix C, shows that 46 Constructed SSO Outfalls are scheduled to be eliminated in the calendar year period 2014-2018. Including the 73 Constructed SSO Outfalls already removed by the District, this computes to a cumulative reduction of 54% of the 222 Constructed SSO Outfalls in the District’s jurisdictional area by 12/31/2018. Seventy Constructed SSO Outfalls are scheduled to be eliminated in the calendar year period 2019-2023. This computes to a cumulative reduction of 85% by 12/31/2023. Twenty-one Constructed SSO Outfalls are scheduled to be eliminated in the calendar year period 2024-2028. This computes to a cumulative reduction of 95% by 12/31/2028. Twelve Constructed SSO Outfalls are scheduled to be eliminated in the calendar year period 2029-2033. This computes to a cumulative reduction of 100% by 12/31/2033. The Capacity Assurance Evaluation reports identify remedial measures associated with elimination projects. It should be noted that the scheduled elimination of 70 Constructed SSO Outfalls in the period 2019-2023, of which 43 are scheduled for the year 2023, is based on the assumption that a follow-up project, if one exists, is the controlling project that removes the Constructed SSO Outfall. Depending on the effectiveness of various conceptual projects, some eliminations of Constructed SSO Outfalls may occur sooner than expected. For example, I/I reduction may reduce flows enough that a Constructed SSO Outfall could be removed and a follow-up relief sewer elimination project would need to be reevaluated. Predecessor projects typically exist as remedial measures in all of the 5-year periods and the need for certain elimination projects may need to be reevaluated based on the effectiveness of those projects. Figure 6-1 (page 6-4) graphically shows the cumulative percent removals of Constructed SSO Outfalls by 5-year periods. The graph indicates that 85% of the Constructed SSO Outfalls are removed by the Consent Decree deadline of 12/31/2023. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 6.

The graph indicates that most of the removals occur in the early years of the capital program. In the first ten years of the plan, 116 Constructed SSO Outfalls are scheduled to be eliminated (in addition to the 73 previously removed by the District). The remaining 33 are eliminated in the second ten year period. 33% 54% 85% 95% 100% 0% 20% 40% 60% 80% 100% 120% 2009‐2013 2014‐2018 2019‐2023 2024‐2028 2029‐2033% RemovedCumulative Percent Constructed SSO Outfall Removal per 5-Year Period Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 6. REMEDIAL REQUIREMENTS (ELIMINATION PROJECTS) Page 6-5 December 31, 2013 Figure 6-2 Number of Constructed SSO Outfalls Removed per 5-Year Period 6.2.3 Remedial Requirements (Elimination Projects) Beyond 2023 In its Master Plan, MSD may propose, subject to EPA approval, to schedule the elimination of no more than 15% of the Constructed SSO Outfalls (excluding the eleven Constructed SSO Outfalls identified in Section 6.2.1 above) later than December 31, 2023, but only if based upon a demonstration of technical need to delay the specific elimination project, and in no event shall the elimination project be completed later than December 31, 2033. Technical need shall refer to project sequencing, acquisition of property rights and other legal requirements, utility coordination and relocation of capital projects by other municipal entities, unknown soil or other conditions, natural unknown impediments, and other similar issues, but shall not include financial feasibility. Table C-1 (page C-1) in Appendix C indicates that 33 Constructed SSO Outfall Eliminations (15%) extend beyond December 31, 2023. As noted above, this is allowable pursuant to the Consent Decree, if there is a technical need. Table C-2 (page C-3) in Appendix C lists each of the Constructed SSO Outfalls that are scheduled to be eliminated beyond 2023, along with the conceptual name of the project that is planned to remove each Constructed SSO Outfall and an explanation of the technical need for the extension of the elimination projects beyond 2023. In many cases, several remedial measure projects are to be constructed in order to allow for a remedial requirement project to remove a Constructed SSO Outfall. For example, it is not uncommon to first perform I/I reduction followed by a period of post-construction monitoring for determination of I/I removal effectiveness in order to remove a Constructed SSO Outfall. If I/I removal effectiveness is not adequate, then a Sanitary relief elimination project may be 73 46 70 21 12 0 10 20 30 40 50 60 70 80 2009‐2013 2014‐2018 2019‐2023 2024‐2028 2029‐2033Number RemovedNumber of Constructed SSO Outfalls Removed per 5-Year Period Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 6.

See Table C-2 (page C-3) in Appendix C for the specific discussions on the 33 Constructed SSO Outfall Eliminations that extend beyond December 31, 2023. 6.3 Remedial Requirement (Elimination Project) Implementation The complete list of elimination projects developed by MSD to meet the requirements of the Consent Decree is presented in Appendix D. The table lists each project name, project number, Constructed SSO Outfalls removed, capital cost, present worth, and a summary of the project scope. Costs are in June 2013 dollars. Each project in Appendix D is listed in alphabetical order with a project number, Constructed SSO Outfalls removed, estimated capital and present worth costs, and a conceptual project scope. The Master Plan identifies 87 remedial requirements (elimination projects) that provide for the elimination of 149 Constructed SSO Outfalls. Projects are conceptual, based on a planning level model. Project scopes are subject to change, depending on effects from detailed design through construction management. As additional project design data become available and a design level model is developed, a project may change in a variety of ways. For example, a proposed sewer diameter or length may increase or decrease based on an updated model; a project may be repackaged, subdivided into smaller projects or merged into a larger project for bidding purposes; and a project may be renamed to better reflect its location or modified scope of work. A conceptual storage project could be modified from aboveground to belowground as more detailed engineering is performed. Changes in anticipated development or population needs may cause a project to be canceled. In addition, a project may be eliminated if post construction monitoring verifies that a follow up project is not necessary. MSD intends to make all such changes at its own engineering and technical discretion and will include detailed information regarding those projects and efforts in its annual reports pursuant to Paragraph 73 of the Consent Decree. In addition to the project scope changes described above when scheduling and implementing the elimination projects, MSD must consider the impact that certain circumstances will have on the planned schedule. In addition to the more obvious schedule impacting circumstances like prolonged or extreme weather conditions or natural disasters, management of easement acquisition durations in some instances can be one of the larger challenges on these sorts of projects. At times, MSD has experienced project delays stemming from unanticipated extra time to acquire easements and other property rights. Acquiring rights from some entities is more challenging than others, for instance railroads are not always responsive to meeting our schedule needs. Acquiring rights from other municipal or government entities does not always lend itself to the eminent domain process and most political bodies and boards have their own unique time schedules which limit MSD's ability to quickly gain approval for the acquisition. Additionally, State statutes that govern MSD's use of eminent domain place very specific time constraints on this process and further sometimes unique circumstances complicate the legal process for acquiring the needed property rights. Recently, easement negotiations with, a non- profit community trail and bike path organization has delayed our ongoing Gravois Creek Trunk Sewer projects. MSD takes extensive efforts to limit the impact that these types of delays have on project schedules but this is an area where situations are beyond MSD's control. Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 6. REMEDIAL REQUIREMENTS (ELIMINATION PROJECTS) Page 6-7 December 31, 2013 As previously noted, the elimination projects are complemented by predecessor remedial measure projects and together form a holistic approach to eliminate Constructed SSO Outfalls and to address SSOs and Building Backups.

CONDITIONS OF APPROVAL Page 7-1 August 29, 2014 7. CONDITIONS OF APPROVAL 7.1 EPA Approval Letters On May 12, 2014, the District received a letter from the EPA dated May 5, 2014, outlining the conditions for approval of the Master Plan which was dated December 31, 2013. The EPA approved the Master Plan with the following two conditions: “The 29-page document (which was enclosed with the letter) entitled “Background Information on All Master Plan Projects” is incorporated into the Master Plan”; and “The 10-page table (which was enclosed with the letter) entitled “Projects to Eliminate Sanitary Sewer Overflows” is the approved schedule for the elimination of the SSOs and is incorporated into the Master Plan”. The letter and the documents referenced above can be found in Appendix E, Conditions of Approval. During subsequent conversations between the District and the EPA, it was decided that the last column in the “Projects to Eliminate Sanitary Sewer Overflows” table be changed from “Project Completion (no later than)” to “Elimination of Constructed SSO Outfall or Known SSO Condition (no later than)” since the actual elimination of a Constructed SSO Outfall or known SSO condition was the agreed upon definition of the term “Project Completion”. For clarification, a new letter dated June 24, 2014 and revised “Projects to Eliminate Sanitary Sewer Overflows” table from the EPA were received by the District. Pursuant to EPA’s conditional approval, the June 24th table titled “Projects to Eliminate Sanitary Sewer Overflows” has been incorporated into the Master Plan and contains the schedule for which MSD will eliminate constructed SSOs and known SSOs. The letter and the revised table can be found in Appendix F, Approved Schedule. 7.2 Progress Reporting The EPA understands that MSD may find it necessary to make changes to the approved schedule (which is contained in the table titled “Projects to Eliminate Sanitary Sewer Overflows”) or may determine that a certain project is no longer required to be completed in order to either eliminate Constructed SSOs, all known SSOs, or building backups to ensure there is adequate capacity in the sewer system, as defined in the Consent Decree. The District will apprise the EPA of their progress in executing the Master Plan by doing the following:  If MSD determines the date by which a SSO will be eliminated as set forth in the “Elimination of Constructed SSO Outfall or Known SSO Condition (no later than)” column of the table titled “Projects to Eliminate Sanitary Sewer Overflows” needs to be modified, MSD will request a change pursuant to Paragraph 30 of the Consent Decree.  Except for changes to the Elimination Dates discussed in the first bullet, MSD will report on the progress of “Projects to Eliminate Sanitary Sewer Overflows” as part of the “Background Information on All Master Plan Projects” in the Consent Decree Annual Report.  MSD will report progress on the projects in the “Background Information on All Master Plan Projects” documents as part of the Consent Decree Annual Report, including describing the Metropolitan St. Louis Sewer District SSO Control Master Plan CHAPTER 7. CONDITIONS OF APPROVAL Page 7-2 August 29, 2014 actions taken to ensure an SSO will not occur when it is determined that a project is not required. When appropriate, MSD may include information in its annual report related to changes to project names, and material changes to project scopes. These changes do not require EPA approval.

Metropolitan St. Louis Sewer District SSO Control Master Plan APPENDIX A Page A-1 December 31, 2013 FLOW METERING – SANITARY TO COMBINED Summary Pursuant to Consent Decree Paragraph 25, a flow metering plan and a list of locations of flow meters to be installed on the Sanitary trunk sewers which convey major flow into the Combined Sewer System are included in this section of the Master Plan. The purpose of the flow metering plan is to document the trend in flows over time to demonstrate the impact elimination projects and remedial measures have on the District’s flows from the Sanitary Sewer System into the Combined Sewer System. Flow Metering Plan The District has developed a monitoring plan to concurrently measure flow level and velocity from which flow rates are calculated. The flow monitoring network will be designed, installed, operated, and maintained to provide representative data of sufficient quality to characterize the collection system responses to dry and wet weather conditions at the monitored sites. Monitoring site conditions, equipment selection and installation, equipment maintenance, and data quality assurance checks will be carried out to optimize accuracy and will conform to good engineering practices, as addressed in the following references:  EPA’s Handbook: Sewer System Infrastructure Analysis and Rehabilitation, EPA/625/6- 91/030, 1991  National Association of Sewer Service Companies Sewerage Rehabilitation Manual  Water Environment Federation Manual of Practice FD-6 – Existing Sewer Evaluation and Rehabilitation, Third Edition MSD has identified approximately 30 locations to monitor major Sanitary flow into the Combined Sewer System. An effort will be made to install meters at the confluence of the Sanitary and Combined sewers; however field conditions or data quality may dictate alternate locations. MSD will document any site changes that may occur during the metering process. The data will be reviewed and processed on a regular basis to ensure a level of quality that will allow for the evaluation of Sanitary trunk sewers which convey major flow into the Combined Sewer System and to verify that the SSO Control Master Plan projects and removals of Constructed SSO Outfalls upstream from the meters will not contribute to the increase of the frequency or volume of downstream CSOs. Site Selection Criteria GIS data, model data, and historic flow meter data were used to identify trunk sewer locations selected for flow monitoring. Meter locations were selected downstream of known SSOs. These locations allow District personnel to monitor Sanitary flows as improvements are made to the collection system and Constructed SSO Outfalls are eliminated, ensuring that wet weather flows to the Combined Sewer System are not increased. Table A-1 (page A-2) lists the flow meter sites with their respective watersheds and Wastewater Treatment Facility Service Areas. The locations are also shown geographically in Figure A-1 (page A-4).

Any meter relocation due to site conditions or bad hydraulics will be reviewed to verify that the intended flow will still be metered. If an appropriate existing site cannot be found or maintained, the construction of a metering manhole will be considered. Data Review and Quality Assurance MSD will conduct a periodic review of data via telemetry to identify any problems with the equipment or site conditions and to assure quality data capture. Site visits may be used to make adjustments to the flow meter equipment in the field and used as calibration data points during data processing. Metropolitan St. Louis Sewer District SSO Control Master Plan APPENDIX A Page A-3 December 31, 2013 Initially, the meter data will be processed on a quarterly basis to identify any subtle problems with the sites that cannot be seen in telemetry “snap-shots” and to determine site specific trends. As site issues are resolved and the flow characteristics become well defined, data processing will occur on a semi-annual or annual basis. Improvements and modifications to the Sanitary or Combined Sewer Systems may require meters to be moved from their original locations. Monitoring Duration Monitoring will begin at least one year prior to the anticipated start of SSO Control Master Plan projects relevant to the flow meter locations to establish baseline flows. Following construction completion of an elimination project, monitoring will continue for approximately one year to capture a typical monitoring season (March 1st through September 30th), or as sufficient to produce valid data showing no increase in Sanitary flow into the Combined system. At such time, the flow meter will be removed.

Acquisition of Property Rights: Obtaining easements from property owners in the area has been difficult in the past. Relief sewer is through an active Country Club and Golf Course. Utility Coordination and Relocation: Both the remedial measures as well as the Elimination Projects are in predominately high density residential areas which increase utility conflicts. 2 Black Creek - Haddington Court Relief Sewers BP-013 BP-017 BP-018 BP-151 BP-583 2024-2028    Project Sequencing: This project is a successor to several remedial measures which include construction of approximately 20,000 feet of 18 foot diameter storage tunnel, rehabilitation of approximately 145,000 feet of 8 to 30-inch sewer, and private I/I reduction for approximately 450 properties. Acquisition of Property Rights: Obtaining easements from property owners in the area has been difficult in the past. Utility Coordination and Relocation: Both the remedial measures as well as the Elimination Projects are in predominately high density residential areas which increase utility conflicts.
