SECTION I - INTRODUCTION
Site Entry and Inspection Objectives
U.S. Environmental Protection Agency, Region 5, inspectors arrived at the Wheelersburg Wastewater Treatment Plant (WWTP) (the "Site" or "Facility"), located at 2974 Hayport Road, at 01:35 PM (ET) on 05/10/2022 for an unannounced inspection. The table above identifies the attendees that participated in the inspection. The Region 5 inspectors presented their credentials to Greg Schackart and Andrew Schackart, the Facility's maintenance staff and lab technician, respectively. The Region 5 Lead Inspector informed them that this was a Region 5 inspection to determine compliance with the Clean Water Act (CWA) and the National Pollutant Discharge Elimination System (NPDES) permit program. The inspection was conducted under the authority of Section 308 of the CWA.
This report is based on information supplied by Facility representatives, observations made by the Region 5 inspectors, and records and reports maintained by the Facility and Region 5 including: direct observations made, photographs taken, physical evidence collected, and measurements taken by the Region 5 inspectors; verbal or written statements provided by Facility representatives during or subsequent to the inspection; and materials, processes, data, photographs, or documents shown, demonstrated, or submitted to the Region 5 inspectors by Facility representatives during or subsequent to the inspection. In addition, information gathered prior to or subsequent to the inspection from a review of U.S. Environmental Protection Agency, state, and public records may be included in this report.
Facility/Site Description
The Region 5 Lead Inspector confirmed the following facility information:
The Facility is publicly owned by Scioto County. It has a design flow of 1.2 million gallons per day (MGD) and serves approximately 7,000 residents connected to a sanitary-only collection system. No industrial users discharge process waste to the WWTP, but the Pepsi facility discharges sanitary waste to the WWTP. The Facility consists of an inflow structure, a bar screen, a trash rake, a flow splitter box, an influent chamber, two oxidation ditches, another splitter box, three clarifiers, an ultraviolet (UV) disinfection channel, two aerobic digesters and a sludge belt press. The Facility discharges into Pine Creek via outfall 001.
According to Mr. Schackart, Scioto County operates 90 pump stations in the collection system area and a couple satellite wastewater treatment plants.

Primary treatment
Secondary treatment
Description
The digester unit includes two aerobic digesters, the sludge press and sludge storing areas.
The primary treatment consists of the influent box, trash bars and an automatic trash rake.
The secondary treatment consists of the oxidation ditches, splitter box, three clarifiers, a UV tank, two aerobic digesters and a sludge belt press.

Solids from the clarifiers are pumped into the two aerobic digesters. The digesters had plants growing in them and at least one of them was almost fully covered with plants growing on top of it. EPA observed the belt press, not operating, in a covered shed just south of the digesters. According to Mr. Schackart, the belt press is operated as needed and belt press leachate is pumped back to the headworks. Next to the belt presser there was the dry sludge storage shed. EPA observed sludge overflowing from the covered shed and exposed to stormwater.

Unit: Primary treatment
Observation #: AH2-OB-001
Contains CBI: No Date: 05/10/2022
EPA started the tour of the facility at the headworks. EPA observed three influent pipes, of which one was discharging. Mr. Schackart stated that the one discharging was influent from the city of Wheelersburg and the other two were influent from Franklin Furnace and return leachate from the digesters. The trash rake was not working at the time of the inspection. There was a trash screen and trash were hand-collected and placed on the side of the inflow channel.

Observation #: AH2-OB-002
Contains CBI: No Date: 05/10/2022
From the inflow channel, flow was routed to the oxidation ditches, which were put in operation in 1970, according to Mr. Schackart. Wastewater in the oxidation ditches flowed in a loop and through four rotors that were spinning continuously to agitate and aerate the ditches.
At approximately 2:00PM, Mr. JP Pickelsimer, county sanitary engineer, joined EPA on the tour of the facility.
From the oxidation ditches, flow was routed to a splitter box and from there to three clarifiers. EPA observed a lot of trash and build-up in all three clarifiers. Wastewater from the clarifiers flowed into the Ultraviolet radiation (UV) channel. The UV system was just a few months old according to Mr. Pickelsimer. From the UV channel, flow was routed to outfall 001 that discharged into Pine Creek. EPA observed a V-notch weir at the outlet of the UV channel, and where effluent flow was measured according to Mr. Schackart, but could not see a depth sensor. Effluent samples were taken from a manhole just south of the UV channel, using an ISCO autosampler that was stored in a shed. Wastewater in the UV channel was dark grey with a lot of sediment and

trash in it. EPA could not observe outfall 001 at the time of the inspection due to flooding of the fields west of Hayport Road where the outfall was under water.
