33

34 Bloomington System Improvements: Project 8084 Description: This project provides for a new Lift Station L-55 in the City of Bloomington. It also includes interceptor expansion as needed. Purpose and Justification: Lift Station L-55 is in need of replacement based on a condition assessment and capacity requirements. This project is located in the City of Bloomington.

35 Blue Lake Plant Improvements: Project 8018 Description: This project consisted of replacing the existing gaseous chemical effluent disinfection system with liquid chemical disinfection; modifying the existing secondary treatment facilities to remove phosphorus to meet the 1 mg/l annual average limit; rehabilitation of facilities nearing the end of their useful life; improvements to the solids processing facilities and odor control; the addition of anaerobic sludge digestion to supplement the existing sludge dryer for reliability and to recover energy for dryer use; and improvements to plant utility systems. Construction of these improvements is nearing completion. The original project included the staged expansion of the plant's capacity. That phase of the project has been postponed to a later date and was removed from this project. Purpose and Justification: In addition to meeting the regulatory requirements of the NPDES permit, the improvements provide increased process reliability and energy recovery.

36 Blue Lake System Improvements: Project 8028 Description: This project will provide improvements to meet the long-term conveyance capacity, reliability, and rehabilitation/replacement needs of the Blue Lake Interceptor System. This system includes gravity sewers, 29 lift stations, and single forcemains from each lift station. Where cost effective, such as in the Victoria area, some lift stations will be replaced by deep gravity sewers using tunnel construction methods. In some cases, small lift stations will be consolidated. The remaining lift stations will be rehabilitated and/or replaced as necessary. Single forcemains will be upgraded to dual forcemains. Gravity sewers will be rehabilitated as necessary. The five major project areas are Victoria, Excelsior, Mound, and Wayzata, and Gravity Sewers (Chanhassen, Eden Prairie, Minnetonka, Prior Lake, and Shakopee). Purpose and Justification: Evaluation of the Blue Lake Area Interceptor System indicates that the existing facilities cannot convey all of the wastewater that will ultimately be generated from within the Blue Lake sewer shed. In addition, many of the sewers, lift stations, and associated forcemains need to be rehabilitated to ensure system reliability and to address odor and corrosion control.

37 Brooklyn Park LS/FM Improvements: Project 8079 Description: This project will provide two new forcemain pipes from L32 in Brooklyn Park to existing pipes in Fridley by river crossing. Improvements to the lift station and rehabilitation of the existing forcemain pipes and downstream gravity sewers are also included. Land acquisition for the site of a future relocated lift station is also included. Purpose and Justification: On June 21, 2012 a forcemain break was reported on the MSB 69U1 forcemain (Lift Station L32) river crossing. The spill occurred on the east bank of the Mississippi River in the City of Fridley within the Girl Scouts Campground. An emergency situation was declared and Lametti and Sons (contractor) was mobilized to the site to repair the break. The leak was located on the north barrel of the two barrel forcemain; above the bottom 45 degree elbow as the forcemain rises up the east bank of the river. Examination of the failed pipe reveals that the failure occurred as a result of pipe wall erosion caused by continuous scoring by gravel and sand trapped and unable to make it up the incline (insufficient flow velocity). The south forcemain barrel is likely in similar condition; and with it being the remaining active barrel it is possible a second break might occur. The 2012 repairs were considered temporary. This project provides for the long-term replacement of the river crossing forcemain facilities.

38 Chaska Lift Station: Project 8039 Description: The project consists of the design and construction of a new larger pumping station at the former WWTP site to provide long-term capacity to serve Chaska and Carver. The project includes the demolition of wastewater treatment facilities from the phased-out Chaska WWTP. Purpose and Justification: Without the project, the projected development within the Cities of Chaska and Carver will cause wastewater flow to exceed the present interim lift station capacity by 2016.

39 Elm Creek Corcoran/Rogers Connections: Project 8085 Description: Under the original Elm Creek Interceptor family of projects (Project 9004), the Metropolitan Council administered the construction of 12 miles of the main stem of the Elm Creek Interceptor. Eight of those miles extend from the CAB Interceptor in Brooklyn Park ((101st Ave N and Noble Ave) westerly to I-94 and CSAH 30 in Maple Grove (Phases I & II and Trench Sheeting). The other 4 miles are located between Elm Road in southern Maple Grove and across northwest Plymouth to Hamel in the City of Medina (Medina Leg). Under a cost-sharing agreement, the City of Maple Grove constructed 4.5 miles of the main stem linking these two Council interceptor segments, paralleling Elm Creek between I-94 southwesterly to Elm Road. Another 1-1/4 miles of a future branch to southeast Corcoran was constructed by Maple Grove. The Council is in the final stages of acquiring ownership of those sewers constructed by the City of Maple Grove. In addition to the above projects, the Council completed the relocation of approximately 7,000 feet of the Elm Creek Interceptor in coordination with MnDOT work along CSAH 81, along with 3,900 feet of the new Dayton-Hassan extension across northern Maple Grove. The relocation resulted from the MnDOT re-design of CSAH 81 in Maple Grove for the future interchange with TH 610 that would have placed major traffic lanes on top of the sewer. The remaining work on the Elm Creek Interceptor consists of two connections serving Corcoran (northeast and south) and part of southeast Rogers. The estimated cost of these remaining connections is $7,000,000. Phase 1 of the Dayton-Hassan Extension was completed in 2008 to within a mile of the border with Corcoran. Because Hassan Township merged with the City of Rogers, the remaining Phase 2 gravity sewer has been renamed the Corcoran/Rogers Connection.

61 Regional Plant Improvements: Project 8078 Description: This project originally consisted of electrical improvements to mitigate arc flash potential and for the replacement of electrical equipment as needed at the regional plants. In 2014 it was expanded to include improvements at the St. Croix Valley and Eagles Point Plants. The St. Croix Valley Plant project includes improvements to the outfall piping and the aeration blower piping. The Eagles Point Plant project includes improvements to the Administration Buildings HVAC system and a locker room expansion. Purpose and Justification: Arc Flash is a recent addition to our electrical code requirements. The arc flash potential was evaluated at our facilities by Square D/Schneider electric. That project developed initial evaluations and assessments of the arc flash ratings for our facilities. The arc flash ratings on some facilities negatively impact our ability to operate those facilities in an efficient manner. Needed improvements will be made to reduce the rating of those facilities to acceptable levels. It is anticipated that some facilities with high ratings may have to maintain their high rating based on life cycle costs and non monetary factors. The existing 36 RCP outfall pipe at the St. Croix Valley plant has been repaired numerous times in an attempt to lessen the scum coming out of the corroded pipe upstream of the discharge point. Replacement of the outfall structure and piping is needed for the wastewater to discharge at the correct location. The existing aeration piping extends from the Blower building and feeds three aeration basin units. Field inspection found air leakage along the 18 inch aeration blower pipe within the Blower building and outside adjacent to the aeration tanks. The existing piping is below ground underneath the Blower building at an inaccessible location. There is a need to replace the blower pipe to eliminate leaks. The noise level from the existing HVAC system is too high within the office area of the Eagles Point plant s Administration Building. The excess noise may be related to the absence of acoustical ceiling tiles, diffuser/damper relationship, and a high volume of air rushing out the grilles. There is a need to reduce the noise levels to standards within the office areas. The locker room is a shared locker room for both men and women. The project will provide for separate locker rooms.

62 Rural Area Improvements: Project 8016 Description: This program provides for the implementation of the region's rural area aspects of the Water Resources Management Policy Plan/Wastewater System Plan.

Extension of interceptor to Elko-New Market. Long-term wastewater service planning for proposed new regional wastewater treatment plants in Anoka, Carver, Hennepin, and Scott Counties. Wastewater treatment plant site acquisition, early interceptor corridor easement acquisition, and any other land acquisition necessary to ensure efficient implementation of the long term Regional Wastewater System Plan. Purpose and Justification: The adopted Water Resources Management Policy Plan/Wastewater System Plan included provisions related to the Rural Area of the region. This program provides the funding to implement those aspects of the plan related to the Rural Area including the acquisition, improvements, and expansion of existing rural area facilities; the long-term wastewater service planning for future regional wastewater treatment plants; and any necessary site and easement acquisition related to the new plants and/or interceptors. Current Rural Area Projects: Project Title Project ID Elko-New Market Interceptor /12 East Bethel WWTP Carver County Crow River WWTP Dakota County New Germany WWTP Scott County WWTP

63 Elko-New Market Interceptor: Projects /12 These projects extend regional sewer service into the southern metro area, starting with Elko-New Market. Elko-New Market is a burgeoning "rural growth center," where urban or suburban-style growth is occurring in the midst of rural land uses. To keep pace with the fast rate of growth, the communities have proposed expanding capacity at their local wastewater treatment plant, which discharges into the Vermillion River. The Metropolitan Council is among the many stakeholders that have studied and discussed capacity issues and determined the best long-term solution is to extend a regional sewer interceptor to serve Elko-New Market. The Vermillion River is a designated trout stream and considered environmentally sensitive. Expanding regional infrastructure to Elko-New Market would relieve the growth pressures on the Vermillion River and better serve the long-term growth needs of the southern metro area, specifically within the Vermillion watershed in Dakota County. The capital costs are $34 million for this phase of the interceptor extension to Elko-New Market. The extension connects with an existing interceptor in southeast Lakeville, diverting wastewater to the Empire Plant in Empire Township for treatment and discharge into the Mississippi River. This interceptor began operation in October, The long-term plan will extend an interceptor from Empire Plant through Castle Rock and Eureka Townships.

67 Seneca Plant Solids Processing: Project 8075 Description: Based on the draft facility plan, the preliminary recommended improvements include renewal of some of solids building facilities, which were originally constructed in 1972 and upgraded in 1995 and energy conservation elements. The project will install new wet scrubbers and caustic addition facilities to allow Seneca s two multiple hearth incinerators to meet future EPA emissions limits. The project also includes energy conservation elements including replacement of thickening centrifuges with gravity belt thickeners, new aeration control valves and aeration blower (aeration efficiency improvements) and re-lighting of the tunnel system. Purpose and Justification: A comprehensive solids management plan for the MCES wastewater treatment facilities was initiated in April, The plan is needed to operate reliable and cost effective solids treatment through future increases in sludge production, a changing regulatory environment, and development of alternative treatment technologies. By March 2016, Seneca is required to meet new emissions guidelines published by EPA in March 2011 for existing multiple hearth incinerators. To meet these new emission limits, the Seneca incinerators will need new wet scrubbers to reliably reduce SO2 levels. Preliminary emissions testing also indicated that caustic addition would reduce SO2. New scrubbers and caustic addition facilities are recommended so that Seneca can comply with the March 2016 requirements. In addition, a condition assessment of the Seneca solids processing facilities was conducted to determine which facilities need renewal to ensure continued reliable service. Based on the condition assessment, the following facilities need renewal: solids building roof, boiler system, warehouse building, primary scum pits, and odor control scrubber. Minor repairs/modifications to the incinerator and flue gas trains are also included in this project.

East Area Plants Miscellaneous Improvements: Project This project provides for the following miscellaneous improvements at the Empire WWTP: aeration tank walkway repairs; aeration tank piping; headworks building ventilation; and the sludge storage pad cover replacement. The project also includes the evaluation of the plant's arc flash rating and determination of any needed improvements. Miscellaneous projects will also be done at the other East area plants under this project. The estimated cost of these miscellaneous improvements is $1,000,000.

69 Empire WWTP Wetland Bank: Project This project will establish a wetland bank at the Empire WWTP. The wetland bank will be used to provide wetland mitigation for MCES projects such as the 1.1 acres wetland mitigation for the Empire outfall project and 3.45 acres wetland mitigation for the South St. Paul Force Main Project. The estimated cost of establishing the wetland bank is $200,000. Food Waste Co-Digestion Study: Project This project will evaluate anaerobic digestion as a renewable energy process using MCES wastewater as a feedstock with or without food waste as a supplemental feedstock. The estimated total project cost is $150,000. MCWD Long Lake Lagoon: Project This project provides for decommissioning activities associated with the Long Lake WWTP lagoon. The estimated cost of the project is $200,000. Rosemount Plant Decommissioning Phase 2: Project All five buildings at the plant have been decommissioned and four of the five are deteriorating while continuing to incur costs for utility service. Building demolition is ultimately needed to reduce the liability and costs of maintaining an inactive site. Prior to building demolition, asbestos and other hazardous materials must be abated. This project will abate any hazardous materials to prepare the buildings for future demolition, which will be performed under a separate contract. Due to its condition and potential for re-use the Control Building is not anticipated to be demolished. The estimated cost of the abatement project is $115,000. Seneca & RMF Elevator Upgrade: Project This project upgrades the Seneca Plant and RMF elevators to comply with the 2007 changes to the Minnesota Elevator Code (special provisions code ). The estimated cost of the upgrade is $780,000. Seneca Plant CFO: Project This project will replace the existing Seneca CFO facilities with a relatively new (2003 vintage) double wide CFO trailer relocated from the Blue Lake project. All utilities to the old CFO trailers will be disconnected and realigned and insulated for the new trailer location. An ADA compliant entrance will be constructed. The estimated cost of the project is $135,000. Systemwide Roofing Program: Project This project will develop, through physical investigation, an assessment of all roofs at the wastewater treatment plants. Based on the results of the assessment, a program will be developed to keep track of roof health and to prioritize and schedule repair and replacement on an annualized basis. The initial cost of the project is $1,000,000, which includes the RMF roof replacement.

70 St. Bonifacius LS/FM Rehabilitation: Project 8082 Description: This project consists of lift station improvements and a new dual forcemain. Purpose and Justification: The lift station is in need of rehabilitation based on an assessment of its condition and a history of its performance. The new duel forcemain will provide reliable conveyance of wastewater, as well as capacity to serve long-term growth.

71 SWC Interceptor-Lake Elmo Connections: Project 8063 Description: This project provides regional interceptors to convey wastewater from Lake Elmo. This project was originally included as part of the South Washington County Interceptor project. It includes two new connections to Lake Elmo. The Lake Elmo East Connection will provide 1.7 MGD of average daily capacity to eastern Lake Elmo. A gravity interceptor sewer would start at I-94 and proceed about 0.4 miles south along Cottage Grove Drive to a new regional lift station to be built in Woodbury. Initially this flow will be temporarily routed through Woodbury trunk sewers. Eventually the flow will be diverted into the planned Northeast Leg of the South Washington County Interceptor. In both cases the flow will be conveyed to the Eagles Point Plant in Cottage Grove via the portion of South Washington County Interceptor along County Road 19 south of Lake Road, which was completed in The first phase of a second, new connection for Lake Elmo, entitled Lake Elmo Forcemain to WONE, was constructed in 2005 under the Small Systemwide Improvements Program (SSIP). The remainder of the project is being constructed under this project. This new connection will provide 0.5 MGD of average daily capacity to southwestern Lake Elmo. The existing 3,600 feet of 12-inch forcemain along Radio Drive will be extended to Lake Elmo by construction of about 3,500 feet of new 12-inch forcemain terminating at the existing Lake Elmo lift station located east of Inwood Avenue. Also, 4,600 feet of the existing 16-inch Woodbury Wilmes Lake Forcemain to the WONE Interceptor has been acquired from Woodbury and will be inspected and rehabilitated as necessary. This wastewater will flow to the Metropolitan Treatment Plant. Purpose and Justification: This project will provide interceptor facilities to convey wastewater from portions of Lake Elmo and northeast Woodbury to the regional plant in Cottage Grove. The project is needed to support growth in this eastern portion of the metropolitan area.

72 Waconia LS/FM Rehabilitation: Project 8083 Description: This project consists of lift station improvements and replacement of the older of two forcemains. Purpose and Justification: The lift station is in need of rehabilitation based on an assessment of its condition and a history of its performance. The replaced forcemain will provide continued reliable conveyance of wastewater, and additional capacity to serve growth.
