PUBLIC NOTICEof

PUBLIC MEETING

Date: February 24, 2010Permit No. MI0022802Detroit Wastewater Treatment Plant

A Public Meeting with the Michigan Department of Natural Resources and Environment (MDNRE) is beingheld to seek additional public input on the proposed modification of the Detroit Wastewater TreatmentPlants National Pollutant Discharge Elimination System (NPDES) Permit No. MI0022802. This meeting willbe held on February 24, 2010, at 7:00 p.m. at the University of Michigan-Dearborn, EnvironmentalInterpretive Center, 4901 Evergreen Road, Dearborn, Michigan 48128. Public comments will be acceptedthrough February 26, 2010.

The MDNRE proposes to modify the NPDES permit issued for the City of Detroit Wastewater TreatmentPlant on September 28, 2007: The proposed modifications include removing the proposed new DetroitRiver Outfall (DRO-2), which is to be replaced with a relocated Rouge River Outfall (RRO-2) that will likelybe less costly to construct. The relocated Rouge River Outfall includes provisions for disinfection andde-chlorination of excess wet weather primary-treated discharges to the Rouge River. Current wet weather

discharges to the Rouge River from Outfall 050 are not disinfected.

The draft permit includes limitations for fecal coliform bacteria and Total Residual Chlorine for the proposedRRO-2 Outfall, as well as limitations and monitoring for other pollutant parameters, and additional permitconditions to ensure protection of water quality standards. The detailed schedule of compliance forconstruction of the RRO-2 will be submitted with the plans and specifications and will be incorporated intothe NPDES permit once approved by the MDNRE.

The modification also includes language which requires the City to submit a report evaluating variousCombined Sewer Overflow (CSO) control alternatives to the Upper Rouge Tunnel (URT) CSO Project thatthe City hopes will be less costly, but that must still comply with Michigan CSO requirements to provideadequate treatment to meet water quality standards at the times of discharge. This permit modificationeliminates the schedule of compliance for the originally-approved URT Project and replaces it with the

alternative evaluation process that includes submitting a recommended alternative and proposed schedulefor completion. The permit will be modified to reflect the alternative and schedule of compliance determinedto be acceptable to the MDNRE and will be public noticed.

The proposed modified permit was on public notice from November 9, 2009, through December 9, 2009.During the public notice period, various parties requested a public hearing on the proposed modificationsbased on water quality concerns.

All interested parties are invited to present comments on the proposed NPDES permit. Persons unable toattend the public meeting and hearing may submit comments through February 26, 2010. This informationwill be considered prior to taking action on the permit.
