STATE OF WISCONSIN DEPARTMENT OF NATURAL RESOURCES PUBLIC NOTICE OF INTENT TO REISSUE A WISCONSIN POLLUTANT DISCHARGE ELIMINATION SYSTEM (WPDES) PERMIT No.WI-0035874-06-0 Permittee: Kossuth Sanitary District No 2, 5808 CTH R, Manitowoc, WI, 54220 Facility Where Discharge Occurs: Kossuth Sanitary District No 2 WWTF, 4024 Rockwood Rd, Manitowoc, WI 54220 Receiving Water And Location: Tributary to the West Twin River in West Twin River of Twin-Kewaunee River in Manitowoc County at SW ¼ of the SW ¼ of Section 25, T20N R23E Brief Facility Description and Summary of Proposed Changes: Kossuth Sanitary District #1 serves a population of approximately 100 people living within the Sanitary District. Wastewater is treated via two parallel trains of two community septic tanks, with each tank having a capacity of 9,870 gallons. Effluent from the septic tanks is sent to a recirculating chamber, from which it is sent to one of three sand filter beds. The surface dimensions of each bed are 40 ft x 45 ft, and each bed consists of three feet of sand, six inches of pea gravel, and one foot of washed gravel. The filtered effluent is conveyed via an underdrain system to a splitter box, where an adjustable weir is used to vary the proportion of the effluent discharged relative to the amount returned to the recirculating chamber. Treated effluent is then discharged to a tributary to the West Twin River. Monitoring frequencies were increased for all parameters except copper. Effluent limitations were added/updated for TSS, ammonia, phosphorus, chloride, e. coli and whole effluent toxicity testing. A compliance schedule was included for the Sanitary District to regionalize with the City of Manitowoc. Permit Drafter's Name, Address, Phone and Email: Amy Garbe, DNR, 141 NW Barstow St Rm 180, Waukesha, WI, 53188, (262) 574-2135, Amy.Garbe@wisconsin.gov Basin Engineer's Name, Address, Phone and Email: Trevor Moen, 625 E County Road Y, Suite 700, Oshkosh, WI 54901, (920) 410-5192, Trevor.Moen@wisconsin.gov The Department has tentatively decided that the above-specified WPDES permit should be reissued. Limitations and conditions which the Department believes adequately protect the receiving water are included in the proposed permit. Land application of waste shall be done in accordance with permit conditions and applicable codes. All land application sites shall be approved prior to their use. To receive a list of approved sites, or to be notified of potential approvals, contact the above-named basin engineer. Proposed Chloride and Phosphorus Variance Denial: The Department has determined that water quality-based effluent limitations (WQBEL) for chloride and phosphorus are needed in this permit to protect aquatic life. While the permittee requested a variance to both the chloride and phosphorus WQBELs pursuant to s. 283.15, Wis. Stats, the permittee has identified regionalization as a long-term compliance option and a facility plan has been submitted and approved. Consequently, the Department is tentatively denying these variances and instead has included a compliance schedule for completing the regionalization project.
