The following violations were noted during the inspection: Inspection Area Description of Violation Performance Standards Documented excessive I&I shall be specifically addressed. Flow data for 2017-2019 shows a variance in average flow ranging by over 100% of dry weather flow contingent on weather events. Permit Condition II (2) requires the permittee to establish a plan for addressing problems in the collection system that are identified during system inspections. Permit Condition I (5) also recommends creating a long-term plan to address known deficiencies and forecasted future needs. Operation & Maintenance Excessive I&I has caused significant interference of the POTW treatment processes. The current (partially operational) WWTP is not able to fully treat influent flows during rain events. NPDES Permit Standard Conditions Part IV(A) defines interferences as, "inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which causes or contributes to a violation of any requirement..."

M. Shane Date (ORC) and Dillon Lundy (Burnsville Public Works) were present and assisted with the inspection. The inspection included a review of all relevant maintenance and operations records, a visit to each pump station. owned and operated by the town, inspection of manholes and gravity sewers in representative areas of town, and a review of flow data a the WWTP during rain events. The system was non -complaint at the time of the inspection due to severe inflow and infiltration (1&1). Several significant deficiencies related to record keeping were also noted: The following items shall be addressed to return the collection system to compliance: According to DRM data and interviews with public works staff, the WWTP experiences severe I&I during rain events, increasing flow to the WWTP by over 100% in some cases and causing frequent exceedances of the NPDES flow limit. The town should pursue a comprehensive and aggressive infrastructure assessment and repair program with a qualified engineering firm to begin addressing this. A general observation of the entire collection system shall be performed annually. Access right of ways, and high -priority lines (creek crossings) shall be visually inspected biannually and these processes shall be documented. Clean and document at least 10% of the collection system on an annual basis, plus problems areas as needed. Maintain the Spill Response Action Plan (SRAP), Sewer Use Ordinance (SUO) and other relevant information in an easy to access location that ail public works staff are made aware of.
