Facility/Site Description
EPA Region 5 lead inspector confirmed the following facility information:
The Facility is publicly owned by Scioto County. It has a design flow of 0.375 million gallons per day (MGD) and serves 964 residents connected to a sanitary-only collection system. No industrial users discharge process waste to the WWTP. The Facility consists of an inflow structure, a spiral screen, an oxidation tank, a splitter box, two clarifiers, a post aeration tank, an ultraviolet (UV) disinfection channel and two aerobic digesters. The Facility discharges into Long Run via outfall 001. The last day of UV disinfection was October 31, 2022. Sludge is hauled to the Wheelersburg WWTP for pressing. The last time sludge was hauled was on October 28, 2022, and the amount was approximately 40,000 gallons. Chain of custody forms and lab reports for samples taken are kept at the Wheelersburg WWTP lab. Long Run is a tributary of Rocky Fork which flows into Scioto River and eventually to Ohio River. Long Run is listed as impaired for the designated uses of Warmwater Habitat and Recreation Primary Contact, with primary pollutants causing impairment Low Oxygen and Bacteria.

Description
There are two aerobic digesters at the Facility.
There are two clarifiers that receive flow from the oxidation tank.
The headworks comprise of the influent pipes and pumps, the spiral screen, the autosampler and the trash collector.
The physical outfall on the south bank of the Long Run and the outfall signage.
Two concentric tanks with four aeration rotors.
This location includes, the post-aeration tank, UV disinfection channel and control panel, final tank and the effluent autosampler.
SECTION II - OBSERVATIONS
Location: Headworks Observation #: AH2-OB-001
Date: 11/08/2022
Weather: Sunny and 45oF
EPA observed the headworks where there were two influent pipes, a spiral screen and a container where the screened solids are disposed, a refrigerated autosampler and the control panel for the spiral screen. EPA did not observe a thermometer in the autosampler and the autosampler lacked power at the time of the inspection.

Location: Oxidation tank Observation #: AH2-OB-002
Date: 11/08/2022
Weather: Sunny and 45oF
EPA observed two influent pipes in the oxidation tank. The oxidation tank comprised of two concentric ellipseshaped tanks and four oxidation rotors. EPA observed excessive foam of two kinds in the oxidation tank. EPA observed thin, white to grey foam in the inner tank and pumice-like grey foam in the outer tank. According to the operator, sludge from the oxidation tank is sent to the aerobic digesters based on the look of the waste in the oxidation tank. The operator also stated that the oxidation tank receives sludge from the two clarifiers every two hours.

Observation #: AH2-OB-003
Date: 11/08/2022
Weather: Sunny and 45oF
EPA observed a dark grey and light brown water in the clarifiers with some solids floating in them. The operator stated that sludge from the clarifiers is pumped to the oxidation tank every two hours and once per month or, once every two weeks to the aerobic digesters. EPA observed accumulated sludge at the splitter box that splits flow from the oxidation tank to the two clarifiers. The operator stated that he scoops the sludge out manually using a bucket.

Location: Post-aeration tank and UV channel
Observation #: AH2-OB-004
Date: 11/08/2022
Weather: Sunny and 45oF
The post aeration tank and the UV disinfection were not operating at the time of the inspection. EPA observed the flowmeter in the final tank and the flowmeter panel with a calibration tag on it. The calibration tag showed the date of last calibration as October 6, 2022. EPA observed the effluent autosampler with a thermometer in it that showed 4oC. EPA observed the water in the final tank and it looked clear. The operator stated that the 24hour composite sampling is done Tuesday to Wednesday and Thursday to Friday for samples required to be taken twice per week for both influent and effluent.

Location: Aerobic digesters Observation #: AH2-OB-005
Date: 11/08/2022
Weather: Sunny and 45oF
EPA observed the two aerobic digesters. The aerobic digesters had a layer of green algae covering approximately 80% and 50% of the surface area, respectively. The operator stated that the blowers for the aerobic digesters, normally operate 24 hours a day, 7 days a week. However, the blowers were not operating at the time of the inspection. The operator stated that that was due to decanting going on at that time.
