<br />. <br /> <br /> <br />Minnesota Pollution Control Agency <br /> <br />November 2, 1999 <br /> <br />The Honorable Stephanie A. Klinzing <br />Mayor, City of Elk River <br />13065 Orono Parkway <br />PO Box 490 <br />Elk River, Minnesota 55330-0490 <br /> <br />INFORMA.T/ON <br /> <br />Re: Biosolids Violations <br /> <br />Dear Mayor Klinzing: <br /> <br />I recently conducted a compliance monitoring survey at the City of Elk River's wastewater <br />treatment plant. The treatment plant was found in compliance for the items I inspected. Since <br />that time, Agency staff have reviewed the City's 1999 biosolids annual report and found that the <br />. City land ~pplied bios()lids with highJ.11olybdenum. . According to Minnesota Rules 7041.1100, <br />the ceiling concentration for molybdenum is 75 mglkg. The molybdenum concentration in the <br />City's land applied biosolids was 105 mglkg. <br /> <br />This is a significant violation. Because this is a first time occurrence, we will not be taking <br />further enforcement action. If there is another violation involving the biosolids land application <br />program, we will enhance enforcement action. <br /> <br />In addition, the City is considered a major NPDES permittee. As such, the US Environmental <br />Protection Agency (EP A) has final authority over its biosolids management program. The EP A <br />is reviewing the NPDES major permittee biosolids annual reports and may act on this occurrence <br />at some future time The MPCA does not wish to duplicate enforcement action for this violation. <br /> <br />If you have any questions concerning this matter, please contact me at 1-800-657-3864 or (218) <br />529-6268 or Jorja Dufresne at (651) 296-9292. <br /> <br />Sincerely, <br /> <br />fWV C .'. i~g9 <br /> <br />~~ <br />Deb Lindlief <br />Majors Unit . <br />North District <br /> <br />-' . .- <br />;". ;. . <br /> <br />. cc: <br /> <br />,-.
