STATE OF WISCONSIN DEPARTMENT OF NATURAL RESOURCES PUBLIC NOTICE OF INTENT TO MODIFY A WISCONSIN POLLUTANT DISCHARGE ELIMINATION SYSTEM (WPDES) PERMIT NO. WI-0061051-10-1 Permittee: Village of Maribel, PO Box 203, Maribel, WI, 54227 Facility Where Discharge Occurs: Maribel Wastewater Treatment Facility, 14511 Pleasant Rd, Maribel, WI 54227 Receiving Water and Location: An unnamed tributary to Kriwanek Creek with discharge outfall located at SE ¼, NW ¼, SE ¼ of Section 23, Township 21 North, Range 22 East, Village of Maribel, Manitowoc County, WI Brief Facility Description: Wastewater is collected from throughout the Village by a conventional gravity sewer system. At the wastewater treatment facility raw wastewaters from two lift stations enters a wet well. The influent then enters the headworks building into a channel where the influent passes a static bar screen. Flow from the bar screen then enters a Palmer Bowlus flume where influent flow is measured continuously with an ultrasonic meter and samples are collected with a flow proportional composite sampler. Hawkins Aqua Hawk 15177A is added to the channel for phosphorus and copper removal prior to entering the settling/septic tanks using a temporary chemical feed system. The wastewater then enters two sets of two settling/septic tanks in series to provide primary sludge settling and storage. Wastewater then flows to a wetwell or "dosing chamber". Centrifugal pumps then send wastewater to four sand filter cells for biological treatment. A perforated PVC underdrain system accepts the filters' effluent and flows to a splitter box. The splitter box diverts some flow back to the dosing chamber and some to a Palmer Bowlus flume to measure the effluent flow rate continuously with an ultrasonic meter and samples are collected with a flow proportional composite sampler. Wastewater then is aerated via a cascade aeration system and is discharged via an outfall to the Kriwanek Creek tributary.

The permittee requested removing all phosphorus multi-discharger variance (MDV) requirements.

Therefore, the MDV is no longer necessary. The department has removed all MDV requirements for phosphorus and include the final TMDL derived limits for total suspended solids and total phosphorus with this permit modification.
