within 30 days L-hat will. allow the wastewater treatment plant to mai.rttain the
assigned eFflueut quality.

33. The following monitoring shall be performed:
1) BOD - 2/month - effluent
2) TSS - 2/month _ effluent
3) Fecal Coliform Bacteria - 2/month - effluent
4) *Chlorine Residual - daily - effluent
5) Flow - daily - influent or effluent
6) Tot_ Nitrogen (NH3, NO2, NO3, organic_) - montbly -
effluent

Micr_owatL -- seconds per square centimeter (uW-5ec/cm2)
8) p1Y - 2/month - effluent
* Monitoring required only when chlorination system in use
Monitoring required only when UV system in use
All monitoring shall be submitted to the Washington Regional Office no later than
30 days following the end of the monitoring month.
