NC0021709 I11 12I 23/02/23 117 18 ici cJ Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) On February 23rd, 2023, Tricia Lowery met with Tim Church (ORC) to perform Compliance Evaluation Inspection at Jefferson WWTP (NPDES PERMIT#NC0021709). This inspection consisted of two parts: 1) in -office file review, and 2) on -site inspection of the treatment facility. Tim Church assisted with the in -office review, and escorted inspector through the facility during the on -site inspection. The attached EPA inspection form detail the areas that were evaluated with their respective comments. Area found to be of concern are: 1. The 2 traveling bridge teritary filters are out of service. Currently facility is bypassing this treatment and sending effluent from secondary clarifiers to chlorine contact chamber. NPDES Permit Part II, Section C(4)(c)(1)(B) states bypass from the treatment facility is prohibited and enforcement action can be taken against a Permittee unless there were no feasible alternatives to the bypass. 2. DWR was not notified of bypass at the time it occured. NPDES Permit Part II, Section C(4)(b)(2) states: The Permittee shall submit notice of an unanticipated bypass as required in Part II.E.6. (24-hour notice).
