Dear Mike:
Following your request for data concerning the BOD and TKN readings
from the present Olympic package plant, I would like to furnish the
following information received from our local Health Department
officials.
The BOD for Olympic obtained by sample on April 29, 1975 has a
reading of 335 influent and an effluent of 11 mg per liter or a
97% reduction. The TKN obtained on June 2, 1975 is 0.50 mg per
liter on the effluent.
It is my understanding from Mr. Ron McMillan of the Health Department
that these readings are very satisfactory and we therefore request
that consideration for our proposed drainage area be approved for
sewage effluent since an identical plant will be used at this proposed
site.
It is imperative that this school open for use on August 15, 1975 and
your immediate consideration of this request would be greatly
appreciated.
If you need further information, please let me know.
Yours very truly,
/
LIGLlet&i' ,
