The hearing is part of the SRF application review process and will allow citizens the opportunity to come forward with any comments or questions about the proposed improvements to the City's drinking water and wastewater infrastructure. The City is required to provide adequate advance public notification of the public hearing 30 days prior to the hearing meeting federal requirements of the SRF program. The City published a public notice on May 20, 2022, in the Telegraph Herald, a locally circulated newspaper. In addition, project documents including design and environmental information related to the proposed projects will be made available for review by the public in advance of the public hearing. Following the public hearing, the City will submit a summary of the public comments and proof of publication to the environmental review specialist at the SRF program department, along with an executed Environmental Information Document. DISCUSSION Proposed improvements in the Old Mill Road and the Mar Jo Hills Road area are to construct a new lift station, dual force mains, and gravity main connections from the existing gravity system to the new pump station. This project will begin to add needed sanitary sewer capacity to more efficiently convey wastewater to the Water & Resource Recovery Center (WRRC). This project is proposed on the south side of Dubuque from Old Mill Road to the existing WRRC. Proposed improvements to the Granger Creek sanitary sewer system, in the Key West area, are to extend sanitary sewer to Tamarack Industrial Park and Twin Ridge subdivision along with capacity improvements to the existing Granger Creek lift station. The sewer extensions will provide sanitary sewer service for the two areas and allow for the decommissioning of the existing septic systems and a two -cell lagoon. The capacity improvements to the existing Granger Creek Lift station will provide sufficient pumping capacity for recently connected areas, along U.S. Highway 151/61/52 and the two new areas to be served with the sewer extensions. Proposed improvements to the City's drinking water system include construction of water main extensions, one booster station, a water tower, and all necessary structures, site improvements, connections and appurtenances. This is proposed in southern Dubuque along the SW Arterial Corridor and Rockdale Road, and in northern Dubuque along Central Ave and in the Olympic Heights area. The environmental review public hearing is part of the SRF loan environmental review process and will allow concerned citizens the opportunity to come forward with any comments or questions about any potential environmental impact of the proposed project. RECOMMENDATION I recommend that the City Council conduct the public hearing, the City will submit a summary of the public comments and proof of publication to the environmental review specialist at the SRF program department, along with an executed Environmental Information Document. REQUESTED ACTION I respectfully request that the City Council to conduct the public hearing and approve the resolution directing staff to submit the required documentation. cc: Jenny Larson, Budget Director William O'brien, WRRC Plant Manager Bob Schiesl, Assistant City Engineer Christopher Lester, Water Department Manager Deron Muehring, Civil Engineer Steve Brown, Project Manager RESOLUTION NO. 236 - 22 APPROVAL OF ENVIRONMENTAL REVIEW AS PROVIDED BY STATE REVOLVING FUND (SRF) LOAN - ENVIRONMENTAL REVIEW OLD MILL ROAD LIFT STATION AND FORCE MAIN PROJECT, GRANGER CREEK SANITARY SEWER SYSTEM IMPROVEMENTS, AND WATER SYSTEM IMPROVEMENTS 2022 Whereas, public notification of the hearing was advertised on May 20, 2022, 30 days prior to the public hearing per SRF IDNR requirements; and Whereas, the environmental review documents as provided by SRF's Department of Natural Resources for the Old Mill Road Lift Station and Force Main Project, Granger Creek Sanitary Sewer System Improvements, and Water System Improvements 2022, were available for public viewing; and Whereas, a public hearing was held on the 20th day of June 2022, at 6:30 p.m. in the Historic Federal Building Council Chambers (and/or by virtual means) 350 W. 6th Street, Dubuque, Iowa, at which time interested persons appeared and heard for or against the proposed environmental review of said Project; and Whereas, a discussion was held on the environmental impacts of said project; and Whereas, a transcript of the public hearing and a summary of public comments will be available for public review.

We encourage public input in this decision making process. 0 IOWA STATE REVOLVING FUND ENVIRONMENTAL INFORMATION DOCUMENT PROJECT IDENTIFICATION Applicant: City of Dubuque County: Dubuque State: Iowa COMMUNITY DESCRIPTION SRF Number: CS192104901 Iowa DNR Project Number: W2022-0094A Location: The City of Dubuque is located in Dubuque County, Iowa approximately 80 miles northeast of Cedar Rapids, Iowa and 60 miles northwest of Clinton, Iowa. Population: The population of Dubuque according to the 2014 Census was 58,436. The anticipated population for the year 2040 for the City of Dubuque is 75,000. Current Waste Collection System: This area of Dubuque's wastewater system, Sewer Shed 4, is currently served by the Granger Creek Interceptor Sewer (Sewer) and the Granger Creek Pump Station (Pump Station). Sewer Shed 4 is approximately 6,300 acres. The Sewer was originally constructed in 1998 and provides sanitary sewer service to the Dubuque Technology Park and the Key West area, along US Hwy 151/61. The Sewer was extended along Granger Creek to the Dubuque Regional Airport in 2015. The sewer consists of 18in and 20in Ductile Iron pipe. The Pump Station consists of two submersible pumps with room for a third. It receives flow solely from the Sewer and pumps the wastewater approximately 60ft to a manhole immediately upstream of the Catfish Creek Pump Station. The Catfish Creek Pump Station conveys the combined flows to the City's Water and Resource Reclamation Center for treatment. The current wastewater system does not consist of the infrastructure for long-term support of Sewer Shed 4. PROJECT DESCRIPTION Purpose: The purpose of this project is to make improvements to the wastewater collection system to enhance their reliability, increase capacity and to replace obsolete system to safely and reliably operate the City of Dubuque's wastewater system for the next 20 years. INVESTING IN IOWA'S WATER www.iowasrf.com EID Page 2 City of Dubuque CS192104901 Proposed Improvements: The proposed project includes extending the gravity sewer across Highway 151/61 in two separate locations. The Tamarack project location will provide sewer connections to the Tamarack Business Park to eliminate the need for existing septic systems. The Twin Ridge location will connect the city -owned collection system and allow the city to decommission an existing two cell lagoon. Both Locations for sewer extensions will involve boring and jacking under U.S. Hwy 151/61. The remaining installation will be completed with open -cut excavations. Modifications to the existing Granger Creek lift station will need to be completed to increase the firm capacity of the lift station. Increasing existing pump sizes, the addition of a third pump, and minor piping and control modifications will be included. Receiving Stream: The treated wastewater from the existing facility is discharged to the Mississippi River, which is classified as Al, B(WW1), and HH. Class Al waters are primary contact recreational use waters in which recreational or other uses may result in prolonged and direct contact with the water, involving considerable risks of ingesting water in quantities sufficient to pose a health hazard. Such activities would include, but not be limited to, swimming, diving, water skiing, and water contact recreational canoeing. Waters designated Class B(WW1) are those in which temperature, flow and other habitat characteristics are suitable to maintain warm water game fish populations along with a resident aquatic community that includes a variety of native nongame fish and invertebrate species. These waters generally include border rivers, large interior rivers, and the lower segments of medium -size tributary streams. Waters designated Class HH are those in which fish are routinely harvested for human consumption or waters both designated as a drinking water supply and in which fish are routinely harvested for human consumption. ALTERNATIVES CONSIDERED Alternatives Considered: The current wastewater system does not consist of the infrastructure for long-term support of Sewer Shed 4; therefore, no alternatives were considered for the Granger Creek Interceptor Sewer gravity sewer extension. For the pump station, two alternatives were considered. Alternative I consists of modifying the existing Granger Creek Pump Station. The modifications would maximize output with pump replacement and force main modifications using the existing well and vaults. The two existing pumps will be replaced with the largest that can be accommodated by the existing doors and wet well. A third pump will be added to further maximize outflow of the pump station. The existing 6in force main will be replaced with 12in pipe to safely accommodate the output of the new pumps. The third pump will be connected to a separate Bin force main which will join the new 12in force main upstream of the meter vault. This alternative includes adding a new flow meter. Alternative II consists of constructing a new, deeper pump station in place of the Catfish Creek Pump Station. This would allow the Sewer to connect directly to the new pump station, eliminating the need for the Granger Creek Pump Station and the "double pumping" that is now occurring from the Granger Creek Pump Station to the Catfish INVESTING IN IOWA'S WATER www.iowasrf.com EID Page 3 City of Dubuque CS192104901 Creek Pump Station. Existing interceptor sewers in the immediate areas will be modified. Reasons for Selection of Proposed Alternative: For the pump station, alternative I is the selected option. Alternative 11 was not selected because the site is not well suited for a new pumping station and would lead to higher construction costs. The site is located within the Mine of Spain and with the floodplain. This option would also present challenges maintaining operation during construction. The project site was selected for the availability of land (it is already City -owned) as well as minimization of the impacts to the environment. MEASURES TAKEN TO ASSESS IMPACT Coordination and Documentation with Other Agencies and Special Interest Groups: The following Federal, state and local agencies were asked to comment on the proposed project to better assess the potential impact to the environment: U.S. Army Corps of Engineers U.S. Fish and Wildlife Service State Historical Society of Iowa (State Historical Preservation Office) Iowa DNR Conservation and Recreation Division Iowa DNR Water Resources Section Citizen Band Potawatomi Indian Tribe Flandreau Santee Sioux Ho -Chunk Nation Iowa Tribe of Kansas and Nebraska Iowa Tribe of Oklahoma Kickapoo Tribe in Kansas Kickapoo Tribe of Oklahoma Lower Sioux Indian Community Council Miami Tribe of Oklahoma Omaha Tribal Council Osage Tribal Council Otoe-Missouria Tribe Pawnee Nation of Oklahoma Peoria Tribe of Indians of Oklahoma Ponca Tribe of Indians of Oklahoma Ponca Tribe of Nebraska Prairie Band Potawatomi Nation Prairie Island Indian Community Sac & Fox Nation of Mississippi in Iowa Sac & Fox Nation of Missouri Sac & Fox Nation of Oklahoma Santee Sioux Nation Shakopee Mdewakanton Sioux Community Sisseton-Wahpeton Oyate INVESTING IN IOWA'S WATER www.iowasrf.com EID Page 4 City of Dubuque CS192104901 Spirit Lake Tribal Council Three Affiliated Tribes Mandan, Hidatsa & Arikara Nations Upper Sioux Tribe Winnebago Tribal Council Yankton Sioux Tribal Business and Claims Committee Dubuque County Historical Society Dubuque Historic Commission No adverse comments were received from any agencies or general public. Conditions placed on the applicant by the above agencies in order to assure no significant impact are included in the Summary of Reasons for Concluding No Significant Impact section. ENVIRONMENTAL IMPACT SUMMARY Construction: Traffic patterns within the community may be disrupted and above normal noise levels in the vicinity of the construction equipment can be anticipated during construction and should be a temporary problem. Adverse environmental impacts on noise quality will be handled by limited hours of contractor work time during the day. Other adverse environmental effects from construction activities will be minimized by proper construction practices, inspection, prompt cleanup, and other appropriate measures. Areas temporarily disturbed by the construction will be restored. Solid wastes resulting from the construction project will be regularly cleared away with substantial efforts made to minimize inconvenience to area residents. Care will be taken to maintain dirt to avoid erosion and runoff. The proposed project will disturb soils over an area greater than one acre; therefore, the applicant is required to obtain an NPDES General Permit Number 2 (for storm water discharge associated with construction activities) and abide by its terms. Provided that this permit is obtained and the terms of which are abided by, no significant impact to surface water quality, fish, shellfish, wildlife, or their natural habitats is expected.Temporary air quality degradation may occur due to dust and fumes from construction equipment. The applicant shall take reasonable precautions to prevent the discharge of visible emissions of fugitive dusts beyond the lot line of the property during the proposed project (567 Iowa Administrative Code IAC 23.3(2)"c"). Historical/Archaeological: The State Historical Preservation Office (SHPO), the Certified Local Government, and various Native American tribes with an interest in the area were provided information regarding the project. The DNR has determined, and the SHPO has concurred (R&C#211131902), that this undertaking will result in "no historic properties affected" based on the scope of the project, the prior use of the project area, and the findings of previous Phase I Archeological Surveys conducted on and adjacent to the project property. However, if project activities uncover any item(s) that might be of archaeological, historical, or architectural interest, or if important new archaeological, historical, or architectural data should be encountered in the project APE, the applicant should make reasonable efforts to avoid further impacts to the property until an INVESTING IN IOWA'S WATER www.iowasrf.com EID Page 5 City of Dubuque CS192104901 assessment can be made by an individual meeting the Secretary of the Interior's professional qualifications standards (36 CFR Part 61). Environmental: According to the Iowa DNR Conservation and Recreation Division, the proposed project will not interfere with any State-owned parks, recreational areas or open spaces. The U.S. Army Corps of Engineers concurs that the project will not impact wetlands provided the terms of Nationwide Permit No. 58 are abided by. The project will not impact any wild and scenic rivers as none exist within the State of Iowa. The U.S. Fish & Wildlife Service Section 7 Technical Assistance website consultation determined, and Iowa DNR Conservation and Recreation Division agree, that the project will not impact threatened or endangered species or their habitats. However, if any State- or Federally -listed threatened or endangered species or communities are found during the planning or construction phases, additional studies and/or mitigation may be required. According to the Iowa DNR Water Resources Section, this project will not impact the 100-year floodplain provided all necessary floodplain development permits, state and local, are obtained and the terms of which are abided by. No adverse impacts are expected to result from this project, such as those to surface water quantity, or groundwater quality or quantity. Land Use and Trends: The project will not displace population nor will it alter the character of existing residential areas. The proposed project is within the present corporate limits of Dubuque in areas zoned residential, commercial, or industrial. No significant farmlands will be impacted. This project should not impact population trends as the presence or absence of existing water/sewer infrastructure is unlikely to induce significant alterations in the population growth or distribution given the myriad of factors that influence development in this region. Similarly, this project is unlikely to induce significant alterations in the pattern and type of land use. Irreversible and Irretrievable Commitment of Resources: Fuels, materials, and various forms of energy will be utilized during construction. POSITIVE ENVIRONMENTAL EFFECTS TO BE REALIZED FROM THE PROPOSED PROJECT Positive environmental effects will be improved treatment of the wastewater from the City of Dubuque, compliance with effluent discharge permit limits, reduced discharge of the pollutants and nutrients to the receiving stream, and improved water quality in the receiving stream. SUMMARY OF REASONS FOR CONCLUDING NO SIGNIFICANT IMPACT • The project will not significantly affect the pattern and type of land use (industrial, commercial, agricultural, recreational, residential) or growth and distribution of population. • The project will not conflict with local, regional or State land use plans or policies. • The project will not impact wetlands provided the terms of Nationwide Permit No. 58 are abided by. INVESTING IN IOWA'S WATER www.iowasrf.com EID Page 6 City of Dubuque CS192104901 • The project will not affect threatened and endangered species or their habitats provided that any tree cutting is conducted between October 1 and March 31 to avoid impacting endangered bats. If any State- or Federally -listed threatened or endangered species or communities are found during the planning or construction phases, additional studies and/or mitigation may be required. • The project will not displace population, alter the character of existing residential areas, or convert significant farmlands to non-agricultural purposes. • The project will not affect the 100-year flood plain provided all necessary floodplain development permits, state and local, are obtained and the terms of which are abided by • The project will not have effect on parklands, preserves, other public lands, or areas of recognized scenic or recreational value. • No historic properties will be adversely affected by the proposed project. However, if project activities uncover any item(s) that might be of archaeological, historical, or architectural interest, or if important new archaeological, historical, or architectural data should be encountered in the project APE, the applicant should make reasonable efforts to avoid further impacts to the property until an assessment can be made by an individual meeting the Secretary of the Interior's professional qualifications standards (36 CFR Part 61). • The project will not have a significant adverse effect upon local ambient air quality provided the applicant takes reasonable precautions to prevent the discharge of visible emissions of fugitive dusts beyond the lot line of the property during the proposed project (567 IAC 23.3(2)"c"). • The project will not have a significant adverse effect upon local ambient noise levels, surface water quantity, groundwater quality or quantity, or water supply. • No significant impact to surface water quality, fish, shellfish, wildlife, or their natural habitats is expected provided that an NPDES General Permit Number 2 (for storm water discharge associated with construction activities) is obtained and the terms of which are abided by. The project description, scope, and anticipated environmental impacts detailed above are accurate and complete to the best to my knowledge.

Population: The population of Dubuque according to the 2014 Census was 58,436. The design population equivalent for the year 2040 is 75,000. Current Waste Collection System: This area of Dubuque's wastewater system, Sewer Shed 4, is currently served by the Granger Creek Interceptor Sewer (Sewer) and the Granger Creek Pump Station (Pump Station). Sewer Shed 4 is approximately 6,300 acres. The Sewer was originally constructed in 1998 and provides sanitary sewer service to the Dubuque Technology Park and the Key West area, along US Hwy 151/61. The Sewer was extended along Granger Creek to the Dubuque Regional Airport in 2015. The sewer consists of 18in and 20in Ductile Iron pipe. The Pump Station consists of two submersible pumps with room for a third. It receives flow solely from the Sewer and pumps the wastewater approximately 60ft to a manhole immediately upstream of the Catfish Creek Pump Station. The Catfish Creek Pump Station conveys the combined flows to the City's Water and Resource Reclamation Center for treatment. The current wastewater system does not consist of the infrastructure for long-term support of Sewer Shed 4. INVESTING IN IOWA'S WATER www.iowasrf.com ETD Page 2 City of Dubuque CS 1921034 01 PROJECT DESCRIPTION Purpose: The purpose of this project is to make improvements to the wastewater treatment infrastructure to enhance their reliability, increase capacity and to replace obsolete system to safely and reliably operate the City of Dubuque's wastewater system for at least the next 20 years. Proposed Improvements: The proposed project includes construction of a new 20 million gallons per day (MGD) wastewater pumping station and new dual force mains constructed from the new lift station directly to the head works at WRRC. Additionally, a proposed 54-inch and 48-inch gravity mains will also be constructed to intercept flow from two interceptor sewers that currently discharge to the Catfish Creek Pump Station (CCPS). A majority of the force main alignment will follow the existing City street right- of-way. The proposed project also includes a force main tie-in point at the WRRC Headworks. This project will initially remove approximately 80% of the flow from CCPS and allow the existing 8 MGD Catfish Creek pump station to serve growth areas along the south side of town. Receiving Stream: The treated wastewater from the existing facility is discharged to the Mississippi River, which is classified as Al, B(WW1), and HH. Class Al waters are primary contact recreational use waters in which recreational or other uses may result in prolonged and direct contact with the water, involving considerable risks of ingesting water in quantities sufficient to pose a health hazard. Such activities would include, but not be limited to, swimming, diving, water skiing, and water contact recreational canoeing. Waters designated Class B(WW1) are those in which temperature, flow and other habitat characteristics are suitable to maintain warm water game fish populations along with a resident aquatic community that includes a variety of native nongame fish and invertebrate species. These waters generally include border rivers, large interior rivers, and the lower segments of medium -size tributary streams. Waters designated Class HH are those in which fish are routinely harvested for human consumption or waters both designated as a drinking water supply and in which fish are routinely harvested for human consumption. ALTERNATIVES CONSIDERED Alternatives Considered: Three alternatives were considered including: 1. Modifications to CCPS and force main, gravity main upgrades, construction of a parallel pumping station. a. Phase I- CCPS Alteration & Force Main: Modifications to increase the firm pumping capacity of the station to 13.5 MGD from 7.74 MGD. This amount of added capacity would eliminate the need for the City to set up and operate a 2,000 gpm (2.88 MGD) temporary bypass pumping system during wet weather ___.TESTING IN IOWA'S WATER www.iowasrf.com ETD Page 3 City of Dubuque CS192TO34 01 conditions to prevent SSO's at CCPS. This alternative would also provide an estimated 2.88 MGD of additional capacity beyond what is needed to convey the existing wet weather peak flow. Along with the alterations to the existing pumping station, a new 30-inch force main would need to be constructed to the headworks of WRRC to convey the flow from the upgraded pump station and an additional pump station under phase III. b. Phase II- Gravity Main Upgrades: Once the CCPS alterations were made, the 5,125 LF of 24-inch and 30-inch gravity sewer leading to the CCPS, lacks capacity to convey enough flow to fully utilize upgraded CCPS. Phase II consists of upgrading the 5,125 LF 30-inch of gravity sewer, upstream of the CCPS, to 72- inch diameter. c. Phase III- Parallel Pumping Station: once the gravity sewer upgrades are completed, the resulting flows will exceed the capacity of the Phase I upgrades to CCPS, resulting in the need to move forward with Phase III. Phase III consists of the addition of a 15 MGD pumping station, to be constructed adjacent to CCPS. 2. System Storage: Usage of storage for peak flow management, in a collection system, requires not only the storage tank, but also a pumping station and force main to convey flows from the system to the storage facility or from the storage facility back into the system. Screening to keep large items out of the storage facility would also be required under this scenario. This alternative also requires improvements to the intercepting sewers, to eliminate local bottlenecks, so flow can be conveyed to the storage location. It also requires the Phase I upgrades to CCPS have been completed as described under Alternative 1. 3. New Pump Station and Force Main: Alternative 3 will provide a new 1S MGD pump station which will be constructed to be expandable to 30 MGD. The pump station will be constructed to easily make incremental adjustments to the pumping capacity. The expandability will be accomplished by modifying the pumps, as flows increase, and ultimately adding a fourth pump to reach the 30 MGD capacity. This single pump station will provide more initial capacity, at 15 MGD, and more final capacity, at 30 MGD, than the two pump stations under alternative 1 combined. This alternative would also allow the existing 7.74 MGD CCPS to be utilized primarily for the mostly developed Sewer Shed 15 and Sewer Shed 4, served by the Granger Creek Interceptor sewer. Shed four is the largest of the sewer sheds and has a high potential for growth. Utilizing the existing 7.74 MGD CCPS and the new 15 to 30 MGD pump station, this alternative will provide the City with an initial combined firm pumping capacity of 22.74 MGD and an ultimate combined firm pumping capacity of 37.74 MGD. INVESTING IN IOWA'S WATER www.iowasrf.com ETD Page 4 City of Dubuque CS 1921034 01 Reasons for Selection of Proposed Alternative: Alternative 1 solves the immediate need of adding capacity to CCPS but does not provide enough capacity for long term needs. Alternative 2 was deemed too expensive due to location, size and both initial and ongoing operating costs. Alternative 3 was deemed the most cost effective and would allow CCPS to operate for approximately 30 years before capacity upgrades to CCPS may need to be completed. The project site was selected for the availability of land, proximity to existing infrastructure, engineering criteria, capital cost, operational costs and considerations, as well as minimization of the impacts to the environment.

The DNR Flood Plain Management Section will determine if the proposed project requires a permit for impacts to the 100-year floodplain. The DNR Conservation and Recreation Division will determine if the project will impact any State-owned lands or State -listed threatened or endangered species. The U.S. Army Corps of Engineers concurs that the project will not impact wetlands provided the terms of Nationwide Permit #58 are abided by.

While the DNR Floodplain Section has not yet commented, we expect the project will not affect the 100-year flood plain. No adverse impacts are expected to result from this project, such as those to surface water quantity, or groundwater quality or quantity. No significant impact to surface water quality, fish, shellfish, wildlife, or their natural habitats is expected to result from this project. Land Use and Trends: The project will not displace population nor will it alter the character of existing residential areas. The proposed project is within the present corporate limits of Dubuque in areas zoned residential, commercial, or industrial. No significant farmlands will be impacted. This project should not impact population trends as the presence or absence of existing water/sewer infrastructure is unlikely to induce significant alterations in the population growth or distribution given the myriad of factors that influence development in this region. Similarly, this project is unlikely to induce significant alterations in the pattern and type of land use Irreversible and Irretrievable Commitment of Resources: Fuels, materials, and various forms of energy will be utilized during construction. POSITIVE ENVIRONMENTAL EFFECTS TO BE REALIZED FROM THE PROPOSED PROJECT Positive environmental effects will be continued safe conveyance of wastewater for the City of Dubuque.

Population: The population of Dubuque according to the 2010 US Census was 57,637. The anticipated population for the year 2040 according to the Comprehensive Plan Imagine Dubuque 2037 for the City of Dubuque is 78,682. Current Source of Water: The City's water comes from a series of nine wells that pull water from underground aquifers: four deep wells in the sandstone of the Cambrian/Ordovician aquifer, and five shallow alluvial wells located on the banks of the Mississippi River. Current Water Treatment and Quality: Treatment for the City's water supply occurs at the Eagle Point Water Treatment Plant (WTP). The WTP has a capacity of 18 MGD, and operates daily to provide for the water demands within the system. At the WTP, water is first aerated to reduce taste and odor parameters and to remove iron. Lime Softening is used to lower the water hardness to acceptable levels. Lime Softening occurs in solids contact clarifiers with the addition of hydrated lime. Following softening, carbon dioxide is dissolved into the water in a recarbonation process, which also adjusts the water's pH back to normal levels. The water is then filtered in gravity filter beds using sand and anthracite media. Following filtration, chemicals are added, prior to storage and distribution from the two ground -level reservoirs at the WTP. Sodium hypochlorite is used for disinfection. Hydrofluorosilic acid is added to drinking water as a measure improve dental health. Orthopolyphosp hate is added for iron sequestration and to inhibit scaling. Treated water quality has historically been compliant with Iowa DNR requirements. INVESTING IN IOWA'S WATER www.iowasrf.com EID Page 2 City of Dubuque FS-31-22-DWSRF-025 Current Distribution System: The City currently provides water service to residents located within and outside the city limits. The City's water service area consists of approximately 19,600 acres of primarily residential area with some commercial and industrial areas. The water system service area includes nine pressure zones. There are a total of 23,381 water customers. The distribution system piping primarily consists of Polyvinyl chloride (PVC) and Ductile Iron (DI) pipe with DI fittings ranging from 4-in to 24-in diameter. The existing water distribution system consists mainly of 6-in, 8-in, 12-in mains. 16-in, 20-in, and 24-in arterial mains are located strategically throughout the system to reinforce the system during peak demands and fire flow conditions, and to provide resiliency in the system. The City currently has ten facilities providing water storage. The growing industrial park near the proposed site is currently served by the City, within Pressure Zone 3, but the connectivity to that area is bottle -necked with respect to looped water main and booster station supply. There is currently no water storage in this area to allow the City to accommodate developed demand along the HWY 61 corridor. The main objective of the project is to extend (and improve as necessary) water storage and distribution to the south end of the City. The project will provide resiliency to existing city infrastructure and address current deficiencies in Pressure Zone 3 related to water storage, pumping stations, and looping. There are secondary benefits to several of the improvements, including adding storage at locations in the City where future development is likely to occur and creating infrastructure that can help the City manage dead-end mains and other areas where water age and water quality can suffer due to lack of circulation. PROJECT DESCRIPTION Purpose: The purpose of this project is to make improvements to the water supply system to ensure that the current and future water supply requirements of the community will be met safely and reliably for at least the next 20 years. Proposed Improvements: This project includes work at four locations referenced as the following: Central Avenue, Olympic Heights, Rockdale Road, and SW Arterial Road. The proposed work at the Central Avenue location includes construction of a water main extension, fire hydrants, valves, a booster station and associated connections/appurtenances. The booster station will include a building, standby electrical generator, as well as site improvements such as a driveway and security fence. The proposed work at the Olympic Heights location includes the construction of a water main extension, fire hydrants, valves, and associated connections/appurtenances. The proposed route here is planned mainly along an existing access road to avoid disturbance to existing wooded areas and a rock bluff. This location also includes the abandonment of an existing booster station which will be replaced by the construction of the new booster station at the Central Avenue location described above. The proposed work at the Rockdale Road location includes the construction of a water main extension, fire hydrants, valves, and associated connections/appurtenances. INVESTING IN IOWA'S WATER www.iowasrf.com EID Page 3 City of Dubuque FS-31-22-DWSRF-025 The proposed work at the SW Arterial Road Location includes the construction of water main extensions along North Cascade Road and SW Arterial Road and the construction of a new water tower. This work includes installation of valves, fire hydrants, and associated connections/appurtenances. The water tower will be an elevated storage tank and will include various site improvements such as a driveway and security fence. ALTERNATIVES CONSIDERED Alternatives Considered: The City also considered a new source well out in the Pressure Zones as an alternative that would solve the community's need to accommodate growth and the resultant need for increased pumping capacity and storage during all flow conditions. Reasons for Selection of Proposed Alternative: This alternative was not deemed feasible due to the large planning and design process associated with integrating a new source to blend with the existing systems. All treatment currently occurs at Eagle Point WTP at the heart of the City. Significant unknowns with mixing differently treated water, which could come back into other Pressure Zones may cause water quality issues. Drilling and sampling the test wells could become a long process as attempts are made to identify an acceptable water quality well. Pursuing utility improvements as identified in this Report allow for the continued expansion of the system out into the south and west growth areas using previously developed investments in distribution mains and storage facilities. The project site was selected for the availability of land (it is already City -owned) as well as minimization of the impacts to the environment. MEASURES TAKEN TO ASSESS IMPACT Coordination and Documentation with Other Agencies and Special Interest Groups: The following Federal, state and local agencies were asked to comment on the proposed project to better assess the potential impact to the environment: U.S. Army Corps of Engineers U.S. Fish and Wildlife Service State Historical Society of Iowa (State Historical Preservation Office) Iowa DNR Conservation and Recreation Division Iowa DNR Water Resources Section Citizen Band Potawatomi Indian Tribe Flandreau Santee Sioux Ho -Chunk Nation Iowa Tribe of Kansas and Nebraska Iowa Tribe of Oklahoma Kickapoo Tribe in Kansas Kickapoo Tribe of Oklahoma Lower Sioux Indian Community Council Miami Tribe of Oklahoma Omaha Tribal Council INVESTING IN IOWA'S WATER www.iowasrf.com EID Page 4 City of Dubuque FS-31-22-DWSRF-025 Osage Tribal Council Otoe-Missouria Tribe Pawnee Nation of Oklahoma Peoria Tribe of Indians of Oklahoma Ponca Tribe of Indians of Oklahoma Ponca Tribe of Nebraska Prairie Band Potawatomi Nation Prairie Island Indian Community Sac & Fox Nation of Mississippi in Iowa Sac & Fox Nation of Missouri Sac & Fox Nation of Oklahoma Santee Sioux Nation Shakopee Mdewakanton Sioux Community Sisseton-Wahpeton Oyate Spirit Lake Tribal Council Three Affiliated Tribes Mandan, Hidatsa & Arikara Nations Upper Sioux Tribe Winnebago Tribal Council Yankton Sioux Tribal Business and Claims Committee Dubuque County Historical Society Dubuque Historic Commission No adverse comments were received from any agencies or general public. Conditions placed on the applicant by the above agencies in order to assure no significant impact are included in the Summary of Reasons for Concluding No Significant Impact section. ENVIRONMENTAL IMPACT SUMMARY Construction: Traffic patterns within the community may be disrupted and above normal noise levels in the vicinity of the construction equipment can be anticipated during construction and should be a temporary problem. Adverse environmental impacts on noise quality will be handled by limited hours of contractor work time during the day. Other adverse environmental effects from construction activities will be minimized by proper construction practices, inspection, prompt cleanup, and other appropriate measures. Areas temporarily disturbed by the construction will be restored. Solid wastes resulting from the construction project will be regularly cleared away with substantial efforts made to minimize inconvenience to area residents. Care will be taken to maintain dirt to avoid erosion and runoff. The proposed project will disturb soils over an area greater than one acre; therefore, the applicant is required to obtain an NPDES General Permit Number 2 (for storm water discharge associated with construction activities) and abide by its terms. Provided that this permit is obtained and the terms of which are abided by, no significant impact to surface water quality, fish, shellfish, wildlife, or their natural habitats is expected. Temporary air quality degradation may occur due to dust and fumes from construction equipment. The applicant shall take reasonable precautions to prevent the discharge of --BESTING IN IOWA'S WATER www.iowasrf.com EID Page 5 City of Dubuque FS-31-22-DWSRF-025 visible emissions of fugitive dusts beyond the lot line of the property during the proposed project (567 Iowa Administrative Code IAC 23.3(2)"c"). Historical/Archaeological: Various Native American tribes with an interest in the area and the Certified Local Government were provided information regarding the project. A Phase I Archeological investigation of the proposed project area has been completed, and a Phase II investigation is currently underway. Results from this investigation will be submitted to the State Historical Preservation Office (SHPO) for review. The project will only proceed as planned if a determination of either "no historic properties affected" or "no adverse affect on historic properties" can be appropriately reached with or without mitigation. However, if project activities uncover any item(s) that might be of archaeological, historical, or architectural interest, or if important new archaeological, historical, or architectural data should be encountered in the project APE, the applicant should make reasonable efforts to avoid further impacts to the property until an assessment can be made by an individual meeting the Secretary of the Interior's professional qualifications standards (36 CFR Part 61). Environmental: A Joint Application was submitted by the City's consultant to the Iowa DNR Conservation and Recreation Division and U.S. Army Corps of Engineers. The DNR Flood Plain Management Section will determine if the proposed project requires a permit for impacts to the 100-year floodplain. The DNR Conservation and Recreation Division will determine if the project will impact any State-owned lands or State -listed threatened or endangered species. The U.S. Army Corps of Engineers will determine if the proposed project will impact wetlands or jurisdictional waters of the United States. The project will not impact any wild and scenic rivers as none exist within the State of Iowa. The U.S. Fish & Wildlife Service Section 7 Technical Assistance website will be consulted to determine that the project will not impact threatened or endangered species or their habitats provided that any tree cutting is conducted between October 1 and March 31 to avoid impacting endangered bats. No adverse impacts are expected to result from this project, such as those to surface water quantity, or groundwater quality or quantity. Land Use and Trends: The project will not displace population nor will it alter the character of existing residential areas. The proposed project is within the present corporate limits of Dubuque in areas zoned residential, commercial, or industrial. No significant farmlands will be impacted. This project should not impact population trends as the presence or absence of existing water/sewer infrastructure is unlikely to induce significant alterations in the population growth or distribution given the myriad of factors that influence development in this region. Similarly, this project is unlikely to induce significant alterations in the pattern and type of land use. Irreversible and Irretrievable Commitment of Resources: Fuels, materials, and various forms of energy will be utilized during construction. POSITIVE ENVIRONMENTAL EFFECTS TO BE REALIZED FROM THE PROPOSED PROJECT Positive environmental effects will be maintained water quality for the citizens of Dubuque. A catastrophic loss of water supply could result in City-wide health impacts _STING IN _ _ ___a'S WATER www.iowasrf.com EID Page 6 City of Dubuque FS-31-22-DWSRF-025 due to a lack of sanitation and the use of other water sources that may not meet Federal drinking water standards.

JANET K. PAPE Commission Number 199859 `- My Comm. Exp. DEC 11, 2022 Ad text : PUBLIC HEARING NOTICE The City of Dubuque will be holding a Public Hearing to review three applications for State Revolving Fund (SRF) loans and to make available to the public the contents of the environmental information documents and the City's project plans. These documents include design and environmental information related to the proposed improvements to the City's drinking water and wastewater infrastructure. The three projects are summarized below: Proposed improvements in the Old Mill Road and the Mar Jo Hills Road area are to construct a new pump station, dual force mains, and gravity main connections from the existing gravity system to the new pump station. This project will add needed sanitary sewer capacity and more efficiently convey wastewater to the Water & Resource Recovery Center (WRAC). This project is proposed on the south side of Dubuque from Old Mill Road to the existing WRRC. Proposed improvements to the Granger Creek sanitary sewer interceptor, in the Keywest area, are to extend sanitary sewer to Tamarack Industrial Park and Twin Ridge subdivision along with capacity improvements to the existing Granger Creek lift station. The sewer extensions will provide sanitary sewer service for the two areas and allow for the decommissioning of the existing septic systems and a two -cell lagoon. The capacity improvements to the existing Granger Creek Lift station will provide sufficient pumping capacity for recently connected areas, along U.S. Highway 151/61/52 and the two new areas to be served with the sewer extensions. Proposed improvements to the City's drinking water system include construction of water main extensions, one booster station, a water tower, and all necessary structures, site improvements, connections and appurtenances. This is proposed in southern Dubuque along the SW Arterial Corridor and Rockdale Rd; and in northern Dubuque along Central Ave and in the Olympic Heights area. The purpose of this Public Hearing is to inform area residents of the community of Dubuque of these proposed actions, discuss the actual costs and user fees associated with these projects, and to address citizens concerns, if any, with the plans. The Public Hearing location and time are as follows: June 20, 2022 6:30 p.m. second -floor Council Chambers Historic Federal Building 350 W. 6th Street Dubuque, Iowa 52001 All interested persons are encouraged to attend this hearing. Written comments on this proposal may also be submitted prior to the hearing.
