AAA" <br /> Metropolitan Council <br /> May 9, 2008 Environmental Services <br /> Jim Eibensteiner—Superintendent <br /> City of Wayzata Public Works <br /> 299 Wayzata Blvd. West <br /> Wayzata, Minnesota 55391 <br /> RE: MCES Monitoring Results-April 1-4, 2008 <br /> Mr. Eibensteiner: <br /> Attached are the Metropolitan Council Environmental Services(MCES)analytical results from <br /> sampling conducted on the three sewer lines discharging into ylayiala's 47 lift sta.ioii from <br /> April 1-4, 2008. <br /> MCES monitoring results indicate that the highest concentrations of oiUgrease are coming from <br /> the sewer line (SP-01), containing the Wayzata Country Club's wastewater. The analytical <br /> results confirmed the visual observations of grease noted in the Country Club's line. On the <br /> second day of monitoring, MCES recorded an oil/grease concentration of 172 mg/L at SP-01. <br /> MCES Waste Discharge Rules identify wastewater in excess of 100 mg/L of oil/grease as a <br /> prohibited discharge. If the wastewater from the Country Club continues to cause problems for <br /> the City of Wayzata's sewer system,and/or it is identified as causing a problem in MCES's <br /> sewer lines, MCES will pursue enforcement action towards the Wayzata Country Club. <br /> Please let me know if we can be of any further assistance. <br /> If you have any questions, please contact me at 651-602-4705 or email me at <br /> bob.golden@metc.state.mn.us. <br /> Sincerely, <br /> •C4411 <br /> Robert H.
