Population: The population of Waterloo according to the 2010 US Census was 68,406. The design year 2040 population is estimated to be 71,797. Current Waste Collection System: The City of Waterloo operates a wastewater collection system that is comprised of approximately 400 miles of sanitary sewers; 9,300 sanitary manholes; 46,240 linear feet of force mains; and 26 lift stations. The City has experienced sanitary sewer overflows and bypassing during wet weather events. In October 2015, the City entered into a Consent Decree with the United States and State of Iowa for the City to take measures to achieve compliance with the Clean Water Act and the City's discharge permit. PROJECT DESCRIPTION Purpose: The purpose of this project is to relieve pipe surcharge and manhole flooding on the sewer upstream and downstream of the existing Titus lift station to better safely and reliably operate the City of Waterloo's wastewater system for at least the next 20 years. EID Page 2 City of Waterloo CS1920935 01 Proposed Improvements: The proposed project consists of construction of a new lift station at the location of the existing Titus lift station. The new lift station will be 12' diameter and approximately 27' deep with a conventional valve vault and flow meter pit. Additionally, approximately 8,000 feet of new force main will be constructed (at a depth up to 27') along Broadway Street to Newton Street to send wastewater to the Park Road lift station. A new generator will be installed. The existing lift station and the housing structure (built in 1955) will be demolished. The proposed work is within City right-of-way in previously disturbed utility trenches. A L T ERNA TI VES CONSIDERED Alternatives Considered: The City considered the following alternatives: continue with existing conditions, replacement of existing station with continued discharge to gravity sewer adjacent to lift station, and replacement of existing station along with new force main. Reasons for Selection of Proposed Alternative: The City chose the replacement of existing station along with new force main to reduce sanitary sewer overflows. A no - action alternative is not viable due to the existing consent decree. 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 EID Page 3 City of Waterloo CS1920935 01 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 Waterloo Community Planning and Development 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. 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"). www.iowasrf.com EID Page 4 City of Waterloo CS1920935 01 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 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: 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. 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. No adverse impacts are expected to result from this project, such as those to surface water quantity, or groundwater quality or quantity. 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. Land Use and Trends: The project will not displace population nor will it alter the character of existing residential areas. 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 fewer sanitary sewer overflows and improved measures towards compliance with the Clean Water Act and the City's discharge permit.
