Findings For: City of Ann Arbor
Document Number: ACO-SW03-003
Parties Involved: City of Ann Arbor
Date Entered: 9/4/2003
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.
Footing Drain Disconnection Project:
In order to reduce flow to the sanitary sewer system, footing drain connections at 155 locations will be removed from the City sanitary sewer system on or before June 30, 2004 and every year thereafter by June 30 through June 30, 2007 or until 620 footing drain connections are completed as required by this ACO. 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.
The City agrees to pay to the State of Michigan (state) twenty-five hundred ($2,500) dollars as partial compensation for the cost of investigations and enforcement activities arising from the discharge of sanitary sewage to the waters of the state. Payment shall be made within thirty (30) days. The City agrees to pay a civil penalty of seventy five hundred ($7,500) dollars for the illegal discharge of sanitary sewage to the waters of the state. Payment shall be made within thirty (30) days. The City agrees to pay stipulated penalties of one thousand ($1,000) dollars per day for each failure to meet the requirements or dates of the corrective program set forth in this ACO. The City shall pay these accrued penalties to the State of Michigan no later than ten (10) days after the end of the month in which the violation occurred.
