J.WHITFORD ALAMANCE COUNTY, NORTH CAROLINA NPDES:NC0021474 Facility Name:City of Mebane WRRF 2.5.1 —Mebane WWTP Improvements Phase 1-4 MGD Expansion.The project includes: • Add a second mechanical screen and second vortex grit removal system at the headworks facility. • Convert one of the two existing aeration basins into a flow equalization basin. • Add a new influent pump station with four submersible pumps (three duty and one standby) sized for peak hour flows of 14.6 MGD. • Replace the existing aeration process with two (2) new 5-stage Bardenpho secondary treatment trains with 17.5-ft SWD and 2.20 MG volume each. • Replace the existing clarifiers with two (2) new 95-ft diameter clarifiers. • Add a new RAS/WAS pump station. • Replace the existing cloth media filters with new, larger denitrification filters. • Construct new chlorine basins to provide the required contact time of 15 minutes at a peak flow of 18.8 MGD. • Convert existing Clarifier 3 to a pre-thickening holding tank. • Repurpose existing RAS/WAS pumps for WAS pumping. • Perform related site work and install major piping required for new equipment. • Install Electrical/Instrumentation and Control equipment, including expanding the fiber-optic network with new PLCs installed as part of the improvements above to result in a true redundant path fiber-optic network; making improvements to the HMI system including redundant I/O servers, high-availability Historian and additional workstations throughout the facility; incorporating any new instruments associated with the above improvements. • Construct a new incoming electrical service to provide dual incoming utility feeds, with two (2) new 2000 KVA transformers to replace the existing 750KVA unit. New power distribution equipment including new main switchgear, generator distribution switchgear, new automatic transfer switches and new load centers. All new main distribution equipment will be house in a new electrical building. • Add one (1) additional 750kW standby generator which will parallel the existing 600kW generator. Two 600KW generators would serve this plant but would not allow for growth. 2.5.2—Mebane WWTP Improvements Phase 2-6 MGD Expansion.Phase 2 consists of: • Upgrade influent pumps for peak hour flows of 18.8 MGD. • Add a third 5-stage Bardenpho train. • Add a third 95-ft clarifier. • Upgrade/addition of RAS/WAS pumps. • Install additional denitrification filters. • Install a 1 MGD reverse osmosis treatment train for all tertiary filtered effluent excessive of 5 MGD. • Convert the other existing aeration basin into an aerated sludge holding tank. • Perform related site work and install major piping required for new equipment. • Install one (1) additional 750kW standby generator which will parallel with other generators. 2.6 — Phase 2 expansion will be planned when the flow reaches 3.2 MGD and the construction will start when the flow reaches 3.6 MGD. 2.7 — Permits will be applied for during design of the plant. Authorization to Construct for WWTP from NCDEQ, NPDES Permit Modification, Erosion Control Permit and NCG01 Construction Stormwater from NCDEQ, Floodplain Development Permit from City of Mebane, Stormwater Permit are the needed permits to obtain.

All due dates for Major Program Elements have been reviewed and are correct. No corrections are noted for the Database at this time. A Headworks Analysis was submitted by the City of Mebane on March 24, 2016 and was approved by PERCS on June 3, 2016. During 2020, LTMP sampling frequencies were increased as outlined in the currently approved LTMP in preparation for submittal of an updated HWA on/before March 31, 2021. The City of Mebane WWTP NPDES permit expired on May 31, 2019. In accordance with Part II.B.10. of this NPDES permit, a permit renewal application was submitted to NC DEQ on November 30, 2018. To date, the permit has not been renewed and the City continues to operate under the administratively continued, expired permit. IWS activity continued during 2020. An updated Industrial Waste Survey was submitted to PERCS on November 23, 2020 and was approved by PERCS on January 13, 2021. The City's next IWS is due on/before January 10, 2026. All SIUs were sampled and inspected in 2020. Inspection dates for each SIU are listed below. A Pretreatment Audit Inspection was performed by Jim Gonsiewski of the Winston- Salem Regional Office on September 15, 2020. No deficiencies were noted and over all the inspection showed the City's pretreatment program to be satisfactory. POTW waste reduction activity is recycling. Newspapers, plastic beverage containers, cardboard, office paper, and aluminum and steel cans are recycled by Waste Industries. Biosolids are dewatered and used in the production of compost by a third party. EMA Resources was the third party contracted for dewatering in 2020. 02/26/2021 City of Mebane Pretreatment Annual Report 2020 Page 3 of 23 Industrial Connections & Solutions, LLC— 6801 Industrial Drive — Permit# 0111 — 40CFR433 Annual inspection of the facility was conducted on October 2, 2020.
