STATE OF WISCONSIN DEPARTMENT OF NATURAL RESOURCES PUBLIC NOTICE OF INTENT TO REISSUE A WISCONSIN POLLUTANT DISCHARGE ELIMINATION SYSTEM (WPDES) PERMIT No.WI-0061107-08-0 Permittee: Westboro Sanitary District #1, P O Box 42, Westboro, WI, 54490 Facility Where Discharge Occurs: Westboro Sanitary District #1, Westboro WI 54490 Receiving Water And Location: Silver Creek within the Upper South Fork of the Jump River Watershed in the Upper Chippewa River Drainage Basin in Taylor County Brief Facility Description and Summary of Proposed Changes: The Westboro Sanitary District owns and operates a wastewater treatment facility that treats the wastes generated by the homes and businesses in the community. The treatment plant designed to treat 18,000 gallons per day, currently treats an average of 11,000 gallons per day (2018 – 2022 data).

Wastewater (influent) generated from approximately half of the homes in the service area is collected in individual septic tanks, with the remainder directly connected to the collection system. At the wastewater treatment facility, the influent flows through four septic tanks in a series before reaching a recirculating tank where water is mixed with partially treated wastewater and evenly distributed over one of eight filter beds constructed of layers of fine and coarse sand/ gravel media. Naturally occurring microorganisms living on the media metabolize the organics found in the wastewater. The water from the filters is collected in an underdrain system and sent back to the recirculating tank, where 20 percent leaves as effluent, and 80 percent is passed through the filters again. After re-filtration, the effluent is disinfected seasonally using an ultraviolet system and discharged into Silver Creek in Taylor County. Chemical phosphorous removal is accomplished by adding alum to the third tank. The solids from the system are pumped regularly to prevent the discharge of accumulated solids to the sand filters. These solids are considered septage and are regulated under NR 113, Wisconsin Administrative Code, for septage disposal.

It is the Department’s intention to renew the permit for another term. The proposed new permit expiration date will be September 30, 2028. Limitations and conditions which the Department believes adequately protect the receiving water are included in the proposed permit. Substantial changes from the previous permit include: [1] Effluent Dissolved Oxygen monitoring and limit has been added this permit term. [2] Effluent Fecal Coliform monitoring and limits have been replaced by Escherichia coli (E. coli) based on revisions to multiple rules. [3] Effluent Phosphorus mass limit was added because Silver Creek is an Outstanding Resource Waters (ORW) at the point of discharge. [4] Effluent annual monitoring for the Nitrogen Series (nitrate +nitrite, total Kjeldahl nitrogen and total nitrogen) has been added to the permit.
