Staff met with NCDEQ Inspector Tim Heim on November 2, 2021 to assist with performance of Collec- tion System inspection. Mr. Heim was escorted to all lift station facilities and sites of high priority lines as requested. There were no significant issues or findings noted during this inspection and therefore, a response to the inspection report was not required; however, a Compliance Inspection Report was received and noted the following items: • A request to add the aerial line crossing the creek in the vicinity of Aiken & Silversteen Roads to the High Priority Line (HPL) list for bi-annual inspections and perform an assessment of the col- lection system for other such lines that may need to be added to the HPL list. • The CS staff currently only includes 3 full time members. Given the relatively high maintenance demands of this collection system, and the continued growth of population in the area served, consideration should be given to providing additional staffing. A technical guide to staffing is provided in the EPA's "Manpower Requirements for Wastewater Collections Systems". • The city has made significant progress in the last decade addressing I&I and the upgrade of col- lection system infrastructure, resulting in a dramatic reduction in SSO's. In response, it should be noted that our current Collections System Division staffs a total of five (5) team members. There are currently four (4)full time employees with one vacant position.
