The assistance of Junior Mobley and other City of Durham staff with this inspection was greatly appreciated. Please find attached to this letter, the BIMS checklist summarizing the inspection. Below is a list of findings developed from the inspection: 1. The permit was reissued and became effective August 16, 2018 and will expire July 31, 2026. The collection system has a permitted flow of 40 MGD and is classified as a Class - 4 collection system. Junior Mobley is listed as the Operator in Responsible Charge with multiple back-up ORC's. 2. The Capital Improvement Plan (CIP) covers a five-year period. The Department of Water Management prepares an annual CIP every year. The CIP identifies the highest -priority projects listed for CIP funding and incorporates those projects into a 5-year prioritized CIP based on target funding levels. 3. Tyrone Battle is responsible for the Sewer Use Ordinance and Fats, Oil, and Grease (FOG) program. Food establishments are inspected once a year. Records are kept on paper and computer. There have been no enforcement actions sent out for past year. Educational materials on proper disposal of grease are in the annual report and in the local newspapers. Bill stuffers are also used. 4. Records review indicated the following: a. 196 miles out of 350 total miles of right of ways were maintained for FY22. Records are maintained b. For FY22, Collection System Maintenance work group has cleaned 113 out of target 115 miles of gravity sewer. Records are maintained.
