THE CITY OF DUNN )
Pursuant to provisions of North Carolina General Statute (G.S.) 143-215.2 and G.S. 143-215.67,
this Special Order by Consent is entered into by the City of Dunn, hereinafter referred to as the
City, and the North Carolina Environmental Management Commission, an agency of the State of
North Carolina created by G.S. 143B-282, and hereinafter referred to as the Commission:
1. The City and the Commission hereby stipulate the following:
(a) The City holds North Carolina NPDES Permit NC0043176 for operation of an existing
wastewater treatment works and for making an outlet therefrom for the discharge of 3.75
MGD treated wastewater to the Cape Fear River, Class WS-V waters of this State in the
Cape Fear River Basin.
Additionally, the City holds Permit Number WQCS00073 for Dunn Collection System,
which includes the operation and maintenance of approximately 88 miles of sewer line.
The City has had persistent issues with inflow and infiltration within this system, which
contributes to flow limit violations at the WWTP as well as Sanitary Sewer Overflows.
At the beginning of 2021, the Division conducted a review of the City's self -monitoring
data and Sanitary Sewer Overflow 5-day reports and determined that the facility was
unable to adequately treat the volume of wastewater it was receiving. The City of Dunn
WWTP was subsequently placed under a moratorium prohibiting the introduction of
additional wastewater in accordance with NCGS 143-215.67.
The City continues to be in noncompliance with permit conditions and limits for flow of
their NPDES Permit NC0043176. The City seeks additional flow allocations totaling
1.522 MGD while repairs and enhancements to the collection system are completed. The
City estimates that inflow and infiltration will be reduced by an equivalent or greater
amount as it completes construction on various infrastructure rehabilitation projects.
This SOC grants an initial allocation of 0.15 MGD upon execution of this agreement and
allows additional requested flow allocations to be granted in phases as sewer and WWTP
rehabilitation projects are completed (see 2(c)). If all projects are completed and
compliance with permit conditions and limits are achieved, the moratorium authorized
under NCGS 143-215.67 shall be lifted upon expiration of this SOC.
(b) Noncompliance with final effluent limitations constitutes, causing, and contributing to

pollution of the waters of this State named above, and the City is within the jurisdiction
of the Commission as set forth in G.S. Chapter 143, Article 21.
(c) The City has secured a grant or has otherwise secured financing for planning, design, and
construction/repairs of the following:
i. Sewer Rehabilitation Project — Golden Leaf — This project will replace or rehab
approximately 2,700 linear feet (10 of sewer line and 13 manholes.
ii. Sewer Rehabilitation Project — CDBG — This project will replace or rehabilitate
approximately:
(a) 2,0091f of sewer line and 8 manholes in West Barrington, N.
Fayetteville, N. King, N. Layton, N. Railroad, and N. Wilson.
(b) 7,1681f of sewer line and 29 manholes in the areas of Burke St, Carr
St, E. Cleveland, N. Clinton, Dubois Circle, E. Granville, and E.
Johnson.
(c) 4,448 if of sewer line and 17 manholes in E. Broad, E. Edgerton, E.
Harnett, N. Lee, McNeil Circle, N. Sampson, N. Washington, and
N.Wilmington
iii. Sewer Rehabilitation Project — USDA Phase 1 — This project will replace or rehabilitate
approximately 9,000 If of sewer line, 42 manholes, and 134 service connections.
iv. Sewer Rehabilitation Project — CWSRF — This project is a system -wide rehabilitation
that targets sewer system sub -basins with highest inflow and infiltration. The project will
see to the replacement and rehabilitation of approximately 26,775 if of sewer line and 50
manholes.
v. Sewer Relocations — NCDOT — NCDOT's 1-95 widening project will include
improvements to the collection system. This includes the replacement of approximately
8,3001f of gravity sewer, 14 service renewals, and 58 manholes with new infrastructure.
This project is not under the jurisdiction of the City, so it will not be included in the SOC
timeline. However, the City may be granted additional flow allocation upon completion
of this project by NCDOT (see 2(c)).
vi. WWTP Rehabilitation Project — CWSRF — This project will include the upgrade of
WWTP clarifiers, chlorine contact basins, and internal process piping to accommodate
higher peak flows through the WWTP. The project will increase hydraulic capacity and
improve clarification and disinfection.
vii. Eastside South FM & Machine Welding Outfall — This project will improve the Eastside
Pumping hydraulic capacity, re-route the Eastside force main, and direct flow to a new
outfall proposed from the Highway 301 corridor to the WWTP. The additional pumping
capacity will help eliminate overflows at the Eastside pumping station. The new force
main and outfall will remove a significant amount of flow from the existing Juniper
Creek Outfall, which has a history of overflows at MH BR-8 near the WWTP.
viii. Black River WWTP Effluent Conveyance System — The new effluent conveyance
system to the existing outfall will allow increased flow to be treated through the plant and
discharged during peak wet weather flow conditions. The additional pumping capacity
will help eliminate overflows at MH BR-8 near the WWTP.
(d) Since this Special Order is by Consent, neither party will file a petition for a contested
case or for judicial review concerning its terms.
