Complaint Investigation Summary Report #: 5105 COMPLAINT ID: C00050240 Site Location: 25100 RIVER RD Activity Summary Activity Date Recorded by 08/12/2019 River 25100. Spoke to Brendan of RWQCB about the analytical results, ranging WONG from about 310 to 1300 mg/L of BOD. He said the target BOD from Pond 4 when it's ready to go to percolation pond is about 150 mg/L, so the results are in line of release from Pond 4 before it has a chance to settle (which is essentially what Pond 4 is, a settling pond). Also received email of the RWQCB 7/31 photos and 8/7 Inspection Report. The report confirms 1.Pond 4 to be unlined, requires berm to be evaluated and certified to be stable by geotechnical engineer Lower water level in Pond 4 till seepage has ceased Evaluate treatment options to comply with WDRs and CaDO Weekly update to include: estimated seepage rates volume of water returned to the facility - locations of any additional temp containment berms - free board levels in Pond 4 - any additional changes and corrective actions Juston of the facility called and stated that the discharge has nearly completely stopped at the time of calling around 12pm; he believes the 500 bags of bentonite (he thinks they are 47 lb bags) that they had placed on the bottom of Pond 4 last week is working. Will either go out or have a staff to go verify this week. Juston also provided a letter demonstrating they have retained the service of engineering consultant GK Guiliani. 08/13/2019 Wrote up official inspection report for inspection on 8/8/19 and Tiffany sent it by AFONSKAIA certified mail. 08/13/2019 CERTIFIED MAIL TO: SOK ESCALON WASTEWATER TREATMENT 25100 E RIVER RD ESCALON, CA 95320 70142120000477423547 09/20/2019 River 25100.

Updated billing address in Envision. 10/03/2019 River 25100. Juston emailed copy of Wallace and Kuhl's assessment of Escalon's intent to begin discharging to Pond which they concur, the RWQCB response to the intent, which they agreed.
