Please note each incident as reported in RIMS. Incident 202002285 is located at MH 54 upstream of the Belmont Pump Station system in Sub -Basin `A'. Roanoke Rapids Sanitary District (RRSD) recently discussed extenuating factors leading to spills at this location; which are predicated on rainfall intensity, duration and ground water levels associated with wet weather conditions as illustrated by the attached basin data. This is further compounded by the amount of rag loading that affects pump performance. RRSD is currently in the process of engaging its consultant to further evaluate conditions leading to Sub -Basin `A' SSOs followed by corrective measures necessary to minimize and eliminate corresponding spills. (See updated proposal attached.) We trust our actions are deemed adequate and prudent and will result in a favorable penalty assessment in order that more Iocal funds may be committed to a mutually satisfactory resolution in this process. Roanoke Rapids Sanitary District gratefully appreciates your time and consideration in this matter. Should you require additional information, please do not hesitate to contact us.

OfriCc PROJECT UNDERSTANDING: The Roanoke Rapids Sanitary District (RRSD) owns and operates sanitary wastewater collection system facilities that serve the City of Roanoke Rapids, the Town of Gaston, parts of Halifax County and some other surrounding areas. The collection system consists of over 145 miles of sewer pipe ranging in size from 8" to 30", six lift stations, and one WWTP. The system is divided into 16 sanitary sewer collection sub -basins. Some of the system has been in place since before 1930. RRSD has performed previous study and SSES work in Sub -Basin A. The results of the previous study indicated some level of 1/1 in this area, and RRSD has addressed the 1/1 through collection system rehab and repairs in the sub -basin. However, RRSD is still experiencing high volumes of flow during wet weather events at the Belmont PS which serves Sub -Basin A. The Belmont PS is a duplex, suction lift pump station and both pumps are required during rain events. Frequently during weather events when both pumps operate RRSD has indicated downstream sewer capacity issues, and when both pumps do not operate in wet weather events the upstream sewer is surcharged and exceeds capacity. In addition to the capacity issues noted in Sub -Basin A, RRSD has also experienced wet weather capacity issues in the Roanoke River Outfall which is located downstream of Sub -Basin A and which flows to the WWTP through a combination of 21" and 30" gravity sewers. The section of the 21" outfall that serves the paper mill has been known to demonstrate some capacity restraints and posed some backups in the lateral that serves the paper mill. As such, RRSD would like to further evaluate the system capacity that serves Sub -Basin A and the capacity in the Roanoke River Outfall. BASIC SERVICES: Based on discussions with the RRSD staff, FNI proposes to provide a phased approach to the collection system evaluation for Sub -Basin A and the Roanoke River Outfall. The first phase includes a desktop analysis of the existing system, development of existing sanitary sewer flows, review of previous study information, and hydraulic modeling to evaluate capacity in these areas. Additional phases to follow Phase I may include additional flow monitoring and modeling and/or field inspection work dependent upon results of the Phase I study. A detailed scope of work is provided below for Phase 1: PHASE I — Desktop CaQacity Analysis and Modeling A. Data Collection and Review 1. Project Kick -Off Meeting,: FNI will conduct an initial meeting with RRSD to review proposed scope of services, study approach, goals, and deliverables of the study. FNI will provide the RRSD with a Data Request Memorandum identifying specific data needs. 4. A peak wet weather model scenario will be evaluated using estimated peaking factors for each sub -basin based on available data or using a system -wide peaking factor based on historical influent flow information from the WWTP. E. Technical Memorandum Report 1. Prepare Draft Technical Memorandum (TM} Report: FNI will prepare a Draft TM Report documenting the all the findings from the desktop analysis and modeling completed in Phase I of the Sub -Basin A and Roanoke River Outfall study. The Draft TM Report will include a description of the data review, graphical results of desktop study and modeling, and recommendations for corrective action, if feasible, and/or additional field investigations or follow up work to further investigate capacity restraints in Sub -Basin A and the Belmont PS and within the Roanoke River Outfall. An electronic PDF version of the report will be submitted for review. 2. Revise and Finalize Alternatives Analysis Report: FNI will revise the report based on RRSD comments and submit five (5) final hard copies and one electronic copy in PDF format of the Final Capacity Study Report. TIME OF COMPLETION: FNI is authorized to commence work on the Project upon execution of this Agreement and agrees to complete the services in accordance with the following schedule: • Complete Phase I — within 180 days from Notice to Proceed • Phase II— to be determined based on results of Phase I study COMPENSATION: The total fee for Basic Services for Phase I shall be the lump sum fee of $116,895.00. The fee includes all costs associated with labor and reimbursable direct expenses.

In accordance with the regulation, the following news release has been prepared and issued to media in the affected _ . county (ies): On August 4th, 2020 Roanoke Rapids Sanitary District had a wastewater spill. During this instance, a total wastewater spill of an estimated 1,050 gallons spilled from the wastewater collection system from Manhole A54, sub -basin 'A', located at 312 Land Street. The spill began at 6:30 a.m. on August 4th and ended on August 4th at 7:40 a.m. Untreated wastewater diluted by heavy, sustained rain from Hurricane Isaias spilled into the waters of the state tributary to the Roanoke River in the Roanoke River Basin when inflow into the sewer system from the runoff of 4 inches of rain exceeded the carrying capacity of the pipes. Preparation is being made for all known repairs necessary to reduce the source of inflow to return the pipe system to service and minimize further discharge. The Division of Water Resources was notified of the event on August 4th, 2020 and is reviewing the matter. For more information contact Roanoke Rapids Sanitary District at (252) 537-9137. Thanks!

Wilmington District Water Management Weekly Status Report -10 August 2020 Weather Summary: Hurricane Isaias resulted in 2.5-3" of rain at our Piedmont projects, with much lesser amounts at Scott and Philpott. Additional rain resulted in weeky rainfall totals of 34" at all projects except Philpott (less than an inch). Chances of summer thunderstorms each day this week, perhaps totaling 1-2 inches. Continued chances of above -normal precip for the remainder of the 2-week outlook, along with near -normal temps. Longer term, the August and Aug -Sep -Oct outlooks favor above -normal precip (along with above -normal temps). Tropical Weather Outlook: An area of low pressure located about 600 miles WSW of the Cabo Verde Islands could develop into a tropical depression during the next day or two while it moves generally westward -however, conditions are forecast to become less conducive for development by the end of the week.
