Findings For: City of Ann Arbor

Document Number: ACO-SW03-003

Parties Involved: City of Ann Arbor

Date Entered: 9/4/2003

DEQ Findings:

The City of Ann Arbor (City) owns and operates a wastewater treatment plant (WWTP). The city discharges treated municipal wastewater from its WWTP to the Huron River authorized by National Pollutant Discharge Elimination System Permit Number MI0022217, issued by the DEQ on December 19, 2000. During heavy rain events, the City's sanitary sewer system experiences heavy inflow and infiltration, resulting in Sanitary Sewer Overflows (SSO's). The city experienced thirteen SSO's and system bypasses between March 1997 and June 2002. From a completed Sanitary Sewer Trunk Line Study, completed in 1995 by the City, determinations of sewer system improvements and specific modifications were identified and the work is ongoing. The discharges to the Waters of the State are in violation of Part 31, Water Resources Protection, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended, (NREPA) MCL 324.3101 et seq.; and the rules promulgated under Part 31.

Certification of flow monitoring and hydraulic modeling shall be conducted system-wide to certify that the system meets or will meet criterion based on a corrective action plan. This certification shall be submitted to the DEQ on or before June 30, 2006. Offset Mitigation Program: The City shall implement an Offset-Mitigation Program that requires, for each new premises connected to the system, there shall be a reduction of 1,680 gallons per day in the City's sanitary sewer system. An annual progress report detailing the number of footing drain locations disconnected and any additional flow removed to offset development from the City sanitary sewer system, shall be submitted to the DEQ on or before July 30 of each year beginning July 30, 2004 and ending July 30, 2007. Swift Run Trunk Project: On or before June 30, 2005, the City shall submit an approvable work plan and accompanying schedule for improvements that are to be made to the Swift Trunk sewer to work toward the elimination of SSO's and to correct capacity issues.

DEQ Penalties:
