How was the SSO remediated (i./e. Stopped and cleaned up)?
Pump contol float was removed from the ladder area where it was hung up where pumps immediately began to
operate as they should . High level alarm float was readjusted to a level that should notify us through an auto
dialer callout system of a high level situation. Discharge was released in a swamp area making pumping and/or
cleaning up of of spilled materials impractical.
As a representative for the responsible party. I certify that the information contained in this report is true and accurate to the
