Thanks for the follow-up Jason. So the volume into Bear Creek was (209 gpm)(180 min) – 22,800 g = 14,820 g, right?

Dave,
It took an hour + for the effluent to crest the CCB walls and out the storm drain; hence, 180 minutes. Industrial Systems arrived 9/14/17 and found our dialer had a mass communications error; there is no repairing this failure. A new one was ordered 9/15/17 and will be installed this week. It was also determined that the pressure transducer in the Effluent Pump Station failed; a new sonar level probe was ordered 9/12/17 and will be installed as soon as it it delivered and my electrician can schedule time.

Hello Jason. I just got done reviewing your calculations and had the following questions related to this part of the 5-day report:
A four hour event is equal to 240 minutes, not 180 minutes.
Even if the event was three hours in duration, the total would be 14,820 gallons, not 15,620 gallons.
According to the first page of the report, the event lasted from 02:32 to 06:52, which is 4-hours and 20 minutes, or 260 minutes. So, substituting this duration of time, the corrected total would be:
(209 gpm)(260 min) = 54,340, and subtracting the backwash volume, the net should be 54,340 g – 22,800 g = 31,540 gallons.
You also said Industrial Systems was to have examined the SCADA system on 9/13/17. Please share with us the results of their findings. Also, please review my calculations for correctness. Thank you.

Hello
We have not yet received the 5 day report. I understand it was being mailed but may we get a scanned copy emailed to us too, today?
Thanks

Jason, Dan, Gerald and Mark,
Thank you notifying us with 24 hours of the release from the chlorine contact basin. Per Condition D5 (page 30) of your NPDES permit, was an OERS report made? Was the Emergency Response and Notification Plan required by your permit implemented?

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,

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

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
