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

Re: Bio-Solids Violation
~
Dear Ms. Lindlief;
The Bio-Solids that the City of Elk River land applied in October and November of
1998 exceeded the ceiling limit for Molybdenum. The Bio-Solids were applied before
. the analysis were received and reviewed. The following steps are being taken to
prevent any future violations:
1) No Bio-Solids will be land applied before lab analysis have been received
and reviewed.
2) A sampling program IS being started to identify the source of the
molybdenum.
3) Once the source has been identified, steps will be taken to eliminate the
problem.
I feel confident, that by following these steps, any future violations Will be avoided.
If you have any questions or comments, I can be reached at 612-441-4918.
