4. Percentage Removal Requirements (BODS and TSS Limitations) (Domestic)
If not presently being complied with, effective immediately, the
arithmetic mean of the total BOD5 and the Total Suspended Solids
concentrations for effluent samples collected in a period of 3U
consecutive days snali not exceed 15 percent of the arithmetic mean of
the concentrations for influent samples collected at approximately ttie
same times during the same period (85 percent removal). This is in
addition to the concentration limitations on Total BOD5 and Total
Suspended Solids.
5. Expansion Requirements (Domestic)
Pursuant to Colorado Law, C.R.S. 1973 25-8-501 (5) and state discharge
permit regulation 6.9.3 (12), the permittee is required to initiate

The design capacity of this domestic wastewater treatment works is
0.012 MGD for hydraulic flow and 25 lbs BOD5 per day for organic
loading..
