Wes Royal (ORC), and Mark Hooper (Towaway Falls POA) were present and assisted with the inspection. While the facility's wastewater treatment components and effluent quality appeared to be compliant at the time of the inspection, the following non -compliant items were noted: The wooden walk boards and wooden railing system are deteriorating and pose a safety hazard to operators and inspectors. The wood railing is in particularly poor condition and the section at the end of the walkway cannot support any significant weight. A fall from this location could result in serious injury or worse. The railing and walk boards should be replaced with an appropriate, professionally installed material immediately. The following additional items were noted at the time of the inspection: Repair the facility wash water supply. Repair and secure the decoupled section of effluent pipe near the outfall.
