    EAU CLAIRE, Wis. -- The City of Stanley has requested approval from the Department of Natural Resources to upgrade its existing wastewater treatment facility.

    The Chippewa County city's treatment facility has historically performed adequately and complied with DNR discharge standards. The facility, however, is more than 20 years old, and needs to be upgraded to provide the capacity needed for projected future residential and industrial growth, and comply with new water quality phosphorus standards.

    The proposed project will be implemented in two separate phases. The recommended first phase includes upgrading the capacity of the existing influent pumping and activated sludge treatment systems, replacement of various aging treatment process equipment, installation of a new chemical-feed phosphorus reduction unit and new ultraviolet light effluent disinfection unit, and construction of a new reed bed unit on city-owned land immediately north of the existing treatment facility site for storage of the waste sludge.

    The second phase, to be implemented within the next five to 10 years, includes installation of a new grit removal unit, construction of a new final clarifier tank, and construction of a new tertiary filtration unit to comply with the new phosphorus standards.

    The treated effluent from the proposed upgraded treatment facility will continue to be discharged to the Wolf River via the existing sewer.

    The estimated construction cost of the first phase is $4,972,000. The estimated annual operation and maintenance cost is $441,000. The city is seeking financial assistance through the USDA Rural Development and the state's Clean Water Fund programs.

    The estimated user charge for the average residential customer is expected to range from approximately $27 to $33 per month upon implementation of the first phase.

    A preliminary environmental assessment has been conducted for the proposed project, and DNR has determined that completion of an environmental impact statement will not be required.

    While this type of action normally does not involve significant adverse environmental effects, the DNR is soliciting public comments regarding potential impacts associated with the proposed project.

    Comments can be directed to Steve Smith at DNR (WQ/3), P.O. Box 7921, Madison, Wis., 53707-7921, or by email at [email protected] or by calling at 608-266-7580. Comments will be accepted through Monday, April 8, 2015.

    Based on comments received, DNR may prepare a formal environmental assessment before proceeding with approval or denial of the proposed project. The analysis would summarize DNR's consideration of the potential impacts of the proposal and any reasonable alternatives.
