The facility was found to be non -compliant with permit #WQ0022725. Below are the findings during the inspection: The backwash function via air scouring for the tertiary filter was not operational during the inspection. The backup generator was not operational and the "warning light" was on for the turbidity meter during the inspection. When the generator was further inspected the display on the generator pointed to an ignition fault. ORC David Phar stated the battery died the morning of the inspection. Michelle Pharr followed up with photo evidence that the generator, the turbidity meter, and backwash function of the tertiary filter are now fully operational. These photos are included in the report and docemented. The Turbidity meter was calibrated on 05/16/2020 Effluent flowmeter was calibrated on 05/01/2020 The 10' x 12' x 13' aeration basin appeared to be fully operation. However, the entire basin was covered with a thick foam. It was unknown what caused the foam layer to form on the basin. All records and reports requested for the inspection were available. Operation and maintenance records were available for review. Upon review of the 07/2020 NDMR discrepancies for total phosphorous, PH, TSS and DO were found between the report and the lab data. On 07/15/2020 PH was 7.46 for the NDMR and 7.46 from lab data, total phosphorous was 0.73mg/I and not found in lab data, TSS was 3.4mg/I in NDMR and 4.55mg/I from lab data and lastly, DO was 3.4mg/I in NDMR and 4.55mg/I in lab data. The 06/2020 NDMR was spot checked with no discrepancies. Michelle Pharr will be followed up with an amended 07/2020 NDMR and corresponding lab data. No discrepancies were found within the amended report. At the time of inspection many of the irrigation nozzles were not fully functional and did not irrigate properly. Due to this the specified acreage in the permit was not being irrigated. The irrigation nozzles require maintenance or fixing in order to correct this issue. Documentation has been provided showing that the irrigation system was fully functional after the inspection by Michelle Pharr. This documentation is included at the end of the report and documented.

Environmental Reference: Slash Creek Irrigation System Dear Mr. Mays, Per your request, as faltow up to the November 19, 2020 Slash Creek impaction, I am providing you with written documentation of the noidng status of the Slash Creek Irrigation System. There are 16 spray irrigation acmes, 1,2,5.6,7,8,9,10,11,12,13,14,15,16,17,18, with B to 10 spray IrrlgaUon nozzles per zone. Post Inspection, all zones ware chocked and ab nozzles are working. Than have boon 5 spray nozzles Identified, when activated, are not consistent with their spray pattern. The owners have now winterized the Irrigation system. We will work on the nozzles that have Irregular spray performance In the spring when the krigatfon system Is Initialized. Best regards, Michelle Pharr
