The permit application consists of- - Cover letter - Form �A — NPDES Application for Permit Renewal - Tables A, B, C,1 and D - Pollutant Analysis results for the years: 2021, 2022, and 2023 - Topographic Map - Process Flow Schematic and Narrative i The Town would like to request that the following modifications be made to the permit: We request that monitoring for BOD, TSS, Ammonia Nitrogen and Fecal Coliform continue to be reduced under the "exceptionally performing facilities" criteria. The attached data (summarized in the following table) indicates that the WWTP effluent has exceeded the minimum criteria for reduced monitoring. The most restrictive summer limits were used for BOD and Ammonia Nitrogen removal calculations. In addition to the monitoring results, the plant meets the other listed criteria in the guidelines.

DCESTER VA FLOAIWO AERATOR Town of Newport NPDES Renewal #NC0021555 Plant Narrative The Town of Newport owns and operates a wastewater treatment plant with a capacity of 1.2 million gallons per day (MGD). The plant is composed of the following treatment processes: • A head works facility consisting of an influent sampler, a Parshall flume to measure incoming flow, a main inflow channel with a mechanical bar screen and a grit removal system, and a bypass channel with a manual bar screen and slide gates to direct flow as needed. • A 3 MGD (peak) influent pump station with variable frequency drives to lift wastewater up to the splixter box for the plants oxidation ditches. • Dual oxidation ditches approximately 0.72 MG in size with dual 75 HP surface aerators on variable frequency drives. The aerators will be controlled by a programmable logic controller (PLC) and dissolved oxygen probe. The PLC will continuously monitor the dissolved oxygen in each ditch and adjust the speed of the surface aerators to maintain optimal dissolved oxygen level while also conserving energy. • Two clarifiers, each having a diameter of 70-feet and a side water depth of 13.5 feet. Equipment within the clarifiers includes a main drive unit, effluent baffles and weirs, a sludge scraper, scum rake and beech, scum pumps, and telescopic valves connected to the sludge take -off. • A storage building for dried sludge storage. • Dual tertiary disc filters. These disc filters accept flow from the two 70' diameter clarifiers, where the filtered effluent is conveyed to a chlorine contact basin. • A chlorine contact facility including a chlorine contact basin that utilizes chlorine feed pumps. These pumps are located next to the chlorine contact basin. A new de -chlorination feed system is installed adjacent to the chlorine feed equipment in a separate enclosure. • Post aeration is provided via a blower and dissolved air system. Effluent is conveyed through a gravity main and effluent Parshall flume to the effluent pumping station. • The effluent 3- MGD (peak) pump station. This station pumps treated effluent through a 12" outfall to the discharge point in the Newport River. The flow will utilize a 12-inch gravity effluent outfall to the Newport River, and will be conveyed via gravity until the flow reaches the point of capacity of the line. At this point it will become an effluent force main and the pumps will pump the effluent flow to the Newport River.
