Dave,
After further calculations, I determined that the overflow to Bear Creek was 15,620 gallons. I am finishing up the 5 day report and should be ready to mail on 9/8/2017.
Thanks,
Jason

Dave,
Our printout at midnight showed a Cl2 residual of 2.55 ppm. That number would have stayed pretty steady during the event.
Thanks,
Jason

Hey Jason. It occurs to me that since you normally don’t dechlorinate before land applying the treated wastewater, the volume that got to Bear Creek probably had a high chlorine residual. Did you take any samples so we have an idea of what the chlorine concentration was in the water that went to Bear Creek? If no samples, then please estimate the likely chlorine concentration in the water that went to Bear Creek. Thanks.

Dave,
At approximately 0233 until 0653 this morning, our Effluent Pumps failed, causing our Chlorine Contact Basin to overflow into the storm drains on the southwest and northwest corners of the Basin. Approximately 125000 gallons of treated effluent drained into Bear Creek. I have yet to determine the cause of the failures. If a determination is found, it will be noted on the spill report that will be submitted within the (5) day period. This is our 24 hour notice. If you have any questions, please contact me.
Regards,
Jason Clifford
