The Applicant proposes to upgrade and improve an existing wastewater treatment plant that serves the City of Cincinnati, Iowa. This proposal includes the following: The existing lagoon infrastructure for primary and secondary treatment will be retained and a 4-cell aerated Horizontal Flow SAGR will be constructed south of the existing facility. Ultra-violet (UV) disinfection for treatment of E.coli is planned for construction at the same location. A waterway will be constructed from the east and a 1.4-acre pond will be built on a small tributary coming from the south. As a result of this project, 1.38 acres of wetland (0.25 forested and 1.13 emergent) would be filled and a yet to be determined amount of stream will be impounded behind the earthen embankment. This project has received a Categorical Exclusion from the USDA Office of Rural Development.
