Other Violations/Staff Remarks:
ORC indiacted "Week of 15th-20th we had extreme weather and caused us to be over on weekly average of effluent TSS and
BOD. Weekly average for BOD was 68.72mg/I. Weekly average for effluent TSS was 86.98mg/I. I had lab sample extra that week
to try and get within permit weekly average but did not make it due to extreme weather. I also have been trying to land apply since
December but could not due to very rainy year." NOV recommended
