3 1.1 PROJECT BACKGROUND 1.0 INTRODUCTION Description of the Existing Dugway Interceptor System The Dugway Interceptor system consists of two main service areas, the Dugway East and the Dugway West. The Dugway East includes the Main Branch, Eddy Branch, and Locke Branch. The Dugway West is comprised of Main Branch D and Main Branch E. Please see Figure 1-1 for the alignment of the sewers. Existing drawings and regulator information of these facilities are provided in Exhibits A and B. The existing Dugway Interceptor connects at the Easterly Interceptor near East 109 th Street. The interceptor (24-30 ) extends south paralleling the concrete culvert near Glenview Avenue. The sewers (18 on each side of the culvert) cross Dupont Avenue near East 107 th Street and proceed south crossing Elk Avenue near East 107 th Street, then crossing Glenville Avenue to East 106 th Street and then south on East 106 th Street and crossing St. Clair Avenue. The sewers parallel East 106 th Street, continue south, crossing Helena Avenue. At East 107 th Street, the sewers parallel Parkwood Drive southeast to Linn Drive near Kimberly Avenue. The sewers (15 on each side of the culvert) run down Linn Drive to Primrose Avenue. The interceptor sewers (12 on each side of the culvert) continue just south of Primrose Avenue and head southeast, crossing East 112 th, East 113 th, and East 114 th Streets. The sewer (12 ) then continues south between Carolina Road and Lakeview Roads to Superior Avenue. Page 3 of 48

4 Figure 1-1. Existing Dugway Interceptor General Description of the Easterly CSO Phase II Facilities Plan In 1998, the Northeast Ohio Regional Sewer District (NEORSD) undertook the Easterly CSO Phase II Facilities Plan (ECSO or ECSO Plan) to identify causes and develop solutions for the activation of combined sewer overflows (CSOs) in the Easterly service district. A system of conveyance and storage facilities were identified to capture combined sewage for treatment in accordance with the United States Environmental Protection Agency (EPA) CSO Policy and the Ohio EPA CSO Control Strategy. The first step taken by the District to implement the Easterly CSO plan was to advance the major CSO control systems to preliminary design. This effort, called the Easterly Advanced Facilities Plan (AFP), has the following components. Page 4 of 48

5 Connector Sewers and Interceptor Relief Storage Tunnels, including associated drop structures Easterly Tunnel Dewatering Pump Station Euclid Creek Pump Station Upgrade The Easterly storage tunnel system will consist of three tunnels Euclid Creek/Dugway (ECT/DST), Doan Valley (DVT) and Shoreline (SST). The Dugway Storage Tunnel (DST) segment of the ECT/DST is a 24-ft diameter rock tunnel that will capture and store CSO from the Dugway Brook areas, as well as a portion of the CSO originating from the Collinwood Interceptor service area. The Doan Valley Tunnel (DVT) is a 17-ft diameter dry-weather conveyance rock tunnel that will also have the capability to store CSO flows during storm events. After storms subside, the captured flows are released by gravity to the proposed Dugway West Interceptor Relief Sewer (DWIRS) system. The DWIRS will connect to the Dugway East Interceptor Relief Sewer (DEIRS) system and convey flow to the Easterly Interceptor for treatment at the Easterly Wastewater Treatment Plant (EWWTP). The DEIRS Posted Contract Documents are provided in Exhibit C. The shallower Shoreline Storage Tunnel (SST) is a 21-ft diameter soft ground tunnel that will capture CSO from the outfalls along the Lake Erie shoreline from downtown to the downstream shaft near Dugway Brook. The Euclid Creek Tunnel (ECT) is a 24-ft rock tunnel that will capture CSO from the balance of the Collinwood Interceptor. The DST and ECT are connected at their downstream shafts and their storage capacities are shared to control CSO outfalls from outer service areas. The downstream ends of DST and ECT are connected to the Easterly Tunnel Dewatering Pump Station (ETDPS) located at the Nine Mile Creek Site. After each storm event, when treatment capacity becomes available at the EWWTP, the pump station begins dewatering operations into the Easterly Interceptor for ultimate wastewater treatment at the plant. These tunnel projects, in conjunction with numerous diversion structures, conveyance conduits, drop shafts, and regulator modifications, all act in unison to provide the necessary CSO level of control for the Easterly drainage basin as established in the consent decree. The DWIRS is related to the ECT/DST in that flow diversion structures from these interceptor relief systems will divert flows to the tunnel system as depicted in the attached exhibits General Description of the Dugway West Interceptor Relief Sewer The DWIRS Advanced Facility Plan (Exhibits D & E) provides preliminary design information for the DWIRS system. The relief sewer addresses many wet weather conveyance needs. The DWIRS consolidates regulator structures. The Page 5 of 48

6 DWIRS also provides conveyance for the 5-year, 6-hour storm in the Dugway West service area as well as conveyance to the DST of combined sewage exceeding the capacity of the interceptor. The DWIRS also enables the DVT to empty dynamically during and after storm events by gravity optimizing the sizing of the DVT and eliminating the need to pump captured CSO. The main facilities included in the DWIRS system are illustrated in Figure 1-2, and consist of: A relief sewer with diameters of 66-inches to 108-inches Modifications to 44 existing regulators, and associated connector sewers to convey flow to the DWIRS system. Three diversion structures which redirect existing combined sewer overflows via new CSO conveyance conduits to the storage tunnel drop structures Three new regulating structures to provide wet weather relief overflows to the Dugway Brook West Branch Culvert One flow divider which splits flow between the DWIRS and a new Diversion Structure Page 6 of 48

8 Table 1-1. Diversion, Regulator and Flow Divider Structure Functions ECSO AFP Name Location Function Name DW-1 DWD-1 East 110th Street north of Diversion Structure Glenview Avenue DW-2 DWF-1 East 109th Street and St. Clair Flow Divider Avenue DWD-2 St. Clair Avenue and Lakeview Diversion Structure Road DWR-1 Helena Avenue and East 107th Regulator Structure Street DWR-2 Linn Drive north of Willowmere Regulator Structure Avenue DW-3 DWD-3 Primrose Avenue and Linn Drive Diversion Structure DWR-3 Superior Avenue and East 120th Street Regulator Structure The upstream section of the DWIRS will commence at Tunnel Shaft DVT-1 where flows from Regulator Structure DWR-3 and the DVT will be diverted into a proposed 108-inch sewer. The DVT will release flows by gravity from its downstream shaft during and after a storm into the DWIRS. This configuration is beneficial because there is available capacity in the Easterly Main Interceptor at the downstream of the Dugway Interceptor system and the storage volume of the DVT can therefore be optimized to its current 17-foot diameter size. From Tunnel Shaft DVT-1, it will be necessary to tunnel the 108-inch sewer along Lakeview Road for a distance of 2,198 feet in rock to Manhole MH 37 located at the intersection of Lakeview Avenue and Primrose Avenue. A mining shaft will be located in an open lot at the northwest corner of this intersection, 67 feet beyond Manhole MH 37. The interim tunneled segment between MH 37 and the tunneling shaft will be abandoned after the construction of Manhole MH 37 is complete. Regulator Structure DWR-3 will be constructed on the existing 84-inch brick storm water outlet (SWO) from Regulator D-58 located at the intersection of Superior Avenue and East 120 th Street. The DWIRS runs in a northwesterly direction to Primrose, turning west on Primrose, Avenue, north on Linn Drive, continuing on East 109 th Street, continuing on Glenview Place, and alongside East 110 th Street to Junction Chamber No. 1 on the Dugway East Interceptor Relief Sewer. Page 8 of 48

9 The DWIRS will include the construction of seven new structures; three diversion structures, three regulator structures and one flow divider. Structure DWR-3 is the most upstream of the structures and DWD-1 is the furthest downstream. Diversion structure DWD-1 DWD-1, a proposed two-stage diversion structure, will be constructed on the DWIRS, with a 66-inch diameter dry weather outlet (DWO) and connections to the DST and the Dugway West Culvert. This structure will also receive flow from the 78-inch DWO of regulator D-61. The new 66-inch relief sewer will continue northeast to make a connection into the 5-foot diameter DEIRS. Flow divider DWF-1 A new flow divider will be constructed on the proposed DWIRS at the intersection of St. Clair Avenue and East 109th Street. DWF-1 will receive flows from the upsized DWO from regulator D-14 and the existing branches of the DWI. Flows up to CSO control will proceed north via the 66-inch DWO. Flows greater than this control level will be diverted east along St. Clair Avenue to DWD-2 through a 60-inch pipe. Diversion structure DWD-2 A diversion structure will be located on St. Clair Avenue, approximately 213 east of East 109th Street and designed to accept flow from DWF-1. This structure will have a 48-inch connection to the DST for flows up to CSO control, and a 60-inch connection to the Dugway East Culvert for flows greater than CSO control. Regulator structure DWR-1 This regulating structure will be constructed near the intersection of Helena Avenue and East 107th Street, at the existing location of regulator D-19. The current SWO of regulator D-16 and an upsized DWO from regulator D-17 will be utilized to deliver flows into this structure. Flows from the existing branches of the DWI as well as the flows from D-19 will be diverted into DWR-1. This structure will then convey flows up to CSO control to the DWIRS and have an overflow connection to the Dugway West Culvert. Page 9 of 48

10 Regulator structure DWR-2 DWR-2 will be constructed on the DWIRS on Linn Drive north of Willowmere Avenue and will receive flow from the existing branches of the DWI. Flows up to CSO control will proceed north through the 66-inch DWO. Flows higher than the level needed for CSO control will be diverted to the Dugway West Culvert. Diversion structure DWD-3 This diversion structure will be constructed on the DWIRS at the intersection of Primrose Avenue and Linn Road. Flows from the new Doan Relief Sewer as well as flows from regulators D-37, D-38, and D-39 will be diverted in to the new relief. Underflows will continue north on Linn Road through the 66-inch DWO. Higher flows, up to the CSO control level, will be diverted to a drop shaft on the DST system, located near the intersection of Primrose Avenue and Lakeview Road. Flows greater than the level required for CSO control will be diverted to the Dugway West Culvert. Regulator Structure DWR-3 Regulator structure DWR-3 will be constructed on the 84-inch brick SWO from Regulator D-58. This structure is located at the intersection of Superior Avenue and East 123rd Street. The DWO from Regulator D-58 will be bulkheaded, thus diverting all interceptor flow into the new sewer. The Dugway West Interceptor Relief Sewer Advanced Facility Plan Report (Exhibits D & E) is divided into nine additional technical sections, which includes the following: Section 2.0 provides a summary of the existing geological conditions, as identified in the Geologic Data Report (GDR) and evaluated in the Geotechnical Design Memorandum (GDM). Section 3.0 provides the hydraulics and operational issues of the DWIRS, including tributary area, capacity, sewer design data, and odor control. Section 4.0 provides the design issues for the diversion, regulator and flow divider structures, including hydraulic controls and design criteria. Section 5.0 presents a summary of required regulator modifications to divert flow to the DWIRS. Section 6.0 provides the design issues for the connecting conduits and relief sewers. A narrative description of each facility is also provided. Section 7.0 presents construction recommendations regarding work area requirements, impacts to existing utilities, traffic and the environment. The required property easements and acquisitions are also identified. Page 10 of 48

11 Section 8.0 presents a summary of the Engineer's estimate of probable cost. This section also identifies the assumptions made, the basis of cost, and specifically excluded items. Section 9.0 presents an outline of the specifications that may be required during final design. Section 10.0 provides requirements for final design and identifies various issues that need to be included in the final design of this project. The Dugway Storage Tunnel Advanced Facility Plan Report/Drawings (Exhibits F & G) and the Doan Valley Storage Tunnel Advanced Facility Plan Report/Drawings (Exhibits H & I) are all included with this RFP. The West Branch of the Dugway Interceptor sewershed consists of approximately 770 acres of tributary combined sewer system. The recommended DWIRS alternative consists of approximately 10,600 feet of relief conveyance sewer. Through modifications at 44 regulators, the construction of diversion structures and various new connector sewers, dry and wet weather flow will be introduced to the DWIRS. Table 1-2 lists the locations where flows are introduced to the DWIRS. Table 1-2. Flow Inputs to the DWIRS Connection Size Connection Origin (in.)

The calibrated flows were checked for reasonableness against the maximum population projections for the service area during the 20-year planning period. These wastewater flows generated by the hydraulic model were varied based on an hourly diurnal pattern typical of residential/light commercial areas. The final design shall evaluate dry weather flows to the DWIRS more extensively. The final design must provide adequate capacity to deliver wet weather flows to the Easterly Main Interceptor and the ECT/DST and also maintain minimum required flow velocities, as described later in this section. After the completion of the AFP, the NEORSD engaged in negotiations with the US Department of Justice, the Ohio EPA and the US EPA to finalize the long term CSO control plan through a consent decree. As part of these negotiations the control of the tunnels were modified to include delivery of the largest peak storm in a typical year, TY Storm 60, to the storage tunnels. This allowed the systems to control an additional overflow in a typical year, but also requires that the consolidation and drop systems have adequate capacity to deliver these flows. Therefore, the flows identified in Table 3.4 of the Dugway West Interceptor Relief Advanced Facilities Plan Report need to include Storm 60. This will be provided to the consultant when the models are updated and run to include this flow regime. This is expected to occur prior to the notice to proceed. The District is evaluating the use of green infrastructure as an alternative CSO control method in the Doan Valley sewershed, as well as the sewersheds in the Dugway and Euclid Creek storage tunnel systems. The evaluation will identify opportunities for reduction of stormwater entering the combined sewer system and subsequent reduction in the size and/or elimination of gray infrastructure. The tentative findings of this evaluation Page 12 of 48

13 and potential impacts to flow and infrastructure in the Doan Valley and Dugway Brook systems will be supplied to the selected consultant by July 15, Infiltration was also quantified for each metering basin during the Easterly CSO Phase II Facilities Planning Project (Metcalf & Eddy, 2002). The quantity of infiltration was estimated based on the flow monitoring data, and defined as being equivalent to approximately 90 percent of the minimum daily dry weather flow observed. An independent estimation of infiltration was performed by determining the total length of sewers, grouped by diameter, in the metering basin and applying an infiltration factor based on the type of pipe joints and age of the system. This independent analysis served as a check to determine, and confirm that the results obtained from the flow monitoring analysis were reasonable. Since the proposed DWIRS diverts flow from the existing interceptor system, this infiltration flow from the existing collection system was included in the basis of design of the proposed system. However, infiltration directly into the proposed sewer was not included in the basis of design. Since few pipe joints will be present in the new sewer, infiltration into the proposed system will likely be minimal and negligible in comparison to the wet weather flows present in the combined system. Total dry weather flow consists of both sanitary flow and dry weather infiltration. Table 1-3 presents a summary of average dry weather flows introduced to the DWIRS. Table 1-3.

The risks and associated likelihood of occurrence as well as impact of occurrence will be summarized in a risk register. The risk register template will be provided by the District. Page 20 of 48

21 Task 1N: Community Impact Assessment The Consultant shall prepare a Community Impact Assessment, with the intent of identifying potential short-term impacts to the community during construction, and long-term impacts that arise as a result of the installed asset. Impacts are considered to be both positive and negative in nature. This project will require all components of the Level 1 and Level 2 Assessments as well as applicable components of the Level 3 Assessment. Level 1 Assessments: Typically underground repairs and improvements to existing assets, in existing easements and right-of-ways, does not expand the footprint of the existing asset to a significant extent and construction is shortterm (less than 6 months) in duration. Level 1 Assessments will typically focus on impacts to local residents (noise, dust, odors, loss of parking, access, inconvenience, etc.); impacts to businesses; places of worship; public agency (i.e. fire, police, schools, Rapid Transit Authority, refuse collection) services; vegetation, pedestrian and vehicular traffic patterns, etc. during construction. Level 2 Assessments: Repairs and improvements that significantly expand beyond the footprint of the original asset, or expand the easement or right-ofway to include community areas not previously impacted by the installation of the original asset. Will also include new aboveground structures and projects of longer term duration (greater than 6 months). Level 2 Assessments will typically include all Level 1 Assessment requirements; however, may also include aesthetic impacts from aboveground structures; potential economic impacts to local businesses; long-term changes to traffic patterns, road degradation, changes in land use, emergency response and other impacts due to long-term construction, and changes or additions to permanent aboveground structures. Level 3 Assessments: Typically new aboveground structures on green field sites where impacts to the community will be permanent from significantly altering the physical condition of the site. Level 3 Assessments may include requirements of Levels 1 and 2 Assessments as applicable; however, typically will include impacts to community socioeconomic conditions; alter future land use plans, land valuations, require future security plans, and other more permanent changes to the community. Page 21 of 48

22 Deliverables: The Consultant will provide a level of specificity in the Assessment (specific names of business impacted, type of impact, term of impact, residential addresses, agencies, community profiles and other community entities impacted), so that the Assessment can be developed into an actionable Community Relations and Communication Plan by the Owner in support of the project. The Assessment will provide a general description of the impacted area, specific areas of impact and evaluate the level of impact to each entity impacted. The assessment will also include maps, drawings, study information, supporting documentation and references in support of the Public Impact Assessment. The Consultant s Assessment will be provided to the Owner as a section within the 30%, 60% and 90% design phase submittals, as the Assessment evolves with additional site and public impact information.
