Dear Si rs:
In accordance with Standard Condition 12, we wish to submit the following notice of non-compliances:
Discharge: 006 Sanitary Treatment Plant Parameter and Permit Limi,:
Fecal Coliform 400 colonies /100 ml Non-Compliance and Date:
Fecal Collform > 400 colonies /100 ml on June 20, 1905.
Cause:
Due to excessive flows, the chlorination system was exhausted. The sample was pulled at a time when the chlorine residual was <.1 ppm.
The residual is normally 2-3 ppm, and is checked every other day.
Corrective Action:
Chlorine tablets were added to the System immediately. Another sample was pulled with the results being zero colonies /100 ml sample.
It was determined that the System was without chlorine for a maximum eight hours out of the seven day period.
