1.0 BACKGROUND
The Irwin Creek Tributary to Remount Road general project area includes a park, golf course,
small commercial businesses, as well as multi-family and single-family residences. Proposed
sewer and storm pipes will be constructed within roads and associated right-of-ways in addition to
private and public owned parcels. Southside Park, formerly a city landfill site operating in the
1920s to 1950s, is part of the construction zone. It is expected that soil and groundwater
encountered during construction has been impacted by the landfill and other historical activities at
known small sites.
A preliminary soil and groundwater investigation was conducted in early 2021 and identified
petroleum hydrocarbons, volatile and semi-volatile chlorinated organics, and elevated metal
contamination. To ensure that the surface water quality is not adversarially impacted by the sewer
construction, CEC is submitting the attached NPDES permit application that includes a
groundwater treatment system. The proposed treatment system will treat the extracted
groundwater prior to discharge into Irwin Creek Tributary.
2.0 PROJECT DESCRIPTION
The project will consist of the construction of approximately 14,000 linear feet(LF)of replacement
sanitary sewer,and the construction of 1,000 LF of 60-inch and 120-inch stormwater pipelines.
Groundwater from access pits and boreholes will be pumped out and treated before discharging
directly into Irwin Creek Tributary,which feeds into the Sugar Creek Watershed. Dewatering and
treatment activities are estimated to last approximately eighteen (18) months. The collection,
treatment, and discharge of treated groundwater will be terminated once construction activities
performed below the groundwater table are completed.
The estimated groundwater flow is up to 75 gallons per minute (GPM). The groundwater will be
transferred to the treatment system from the construction via submersible pumps. The proposed
treatment system can treat up to 100 GPM or 144,000 gallons per day. The requested NPDES
permit is for maximum treatment system flow of 100 GPM or 0.144 million gallons per day.
3.0 ENGINEERING ALTERNATIVES ANALYSIS
The Engineering Alternatives Analysis (EAA) is submitted with NPDES permit application. The
EAA did not identify alternative discharge locations for the treated or untreated groundwater.

1.0 BACKGROUND
The Irwin Creek Tributary to Remount Road general project area includes a park, golf course,
small commercial businesses, as well as multi-family and single-family residences. Proposed
sewer and storm pipes will be constructed within roads and associated right-of-ways in addition to
private and public owned parcels. Southside Park, formerly a city landfill site operating in the
1920s to 1950s, is part of the construction zone. It is expected that soil and groundwater
encountered during construction has been impacted by the landfill and other historical activities at
known small sites.
A preliminary soil and groundwater investigation was conducted in early 2021 and identified
petroleum hydrocarbons, volatile and semi-volatile chlorinated organics, and elevated metal
contamination. To ensure that the surface water quality is not adversarially impacted by the sewer
construction, CEC is submitting the attached NPDES permit application that includes a
groundwater treatment system. The proposed treatment system will treat the extracted
groundwater prior to discharge into Irwin Creek Tributary.
2.0 PROJECT DESCRIPTION
The project will consist of the construction of approximately 14,000 linear feet(LF)of replacement
sanitary sewer, and the construction of 1,000 LF of 60-inch and 120-inch stormwater pipelines.
Groundwater from access pits and boreholes will be pumped out and treated before discharging
directly into Irwin Creek Tributary,which feeds into the Sugar Creek Watershed. Dewatering and
treatment activities are estimated to last approximately eighteen (18) months. The collection,
treatment, and discharge of treated groundwater will be terminated once construction activities
performed below the groundwater table are completed.
The estimated groundwater flow is up to 75 gallons per minute (GPM). The groundwater will be
transferred to the treatment system from the construction via submersible pumps. The proposed
treatment system can treat up to 100 GPM or 144,000 gallons per day. The requested NPDES
permit is for maximum treatment system flow of 100 GPM or 0.144 million gallons per day.

3.0 ENGINEERING ALTERNATIVES ANALYSIS
3.1 EVALUATION OF WASTEWATER DISCHARGE TO SURFACE WATERS
CEC reviewed Low-Flow Characteristics of Streams, published by the USGS in 1993, to obtain
the following stream flow data for Little Sugar Creek Watershed which includes Irwin Creek:
Drainage Area: 40.80 square miles
Summer/Winter 7Q10: 34 cubic feet per second(cfs)
30Q2 Flow: 87 cfs
W7Q10 Low Flow: 55 cfs
Average annual unit runoff: 12 cfs/sq.mi
Irwin Creek from source to Little Sugar Creek is classified as a Class C (fishable/swimmable)
water located within the Catawba River Basin and is listed as an impaired waterway on the North
Carolina 303(d) List. The total maximum daily limits (TMDLs) include a fecal coliform limit of
less than 9.4x1012 cfu/100 mL and a turbidity limit of less than of 50 NTU. There is also a TMDL
for dissolved oxygen of no less than a daily average of 5 mg/L and instantaneous value of 4 mg/L
during 7Q10 stream flow conditions.
The proposed groundwater treatment system consists of a 1,100-gallon surge tank, two parallel
particle filters, two 1,000-pound carbon vessels connected in series, and ancillary piping,
instrumentation, and valving. The system has a flow capacity of 100 GPM and will have an
operating flow rate of 75 GPM. Groundwater generated by dewatering activities will be pumped
to the surge tank to equalize flow and settle larger suspended solids. Pumps 1 and 2 will transfer
the supernatant through the particle filters to the carbon vessels that contain virgin coconut carbon.
CEC anticipates that the treatment system will sufficiently remove organics and turbidity to levels
below detection. The process flow diagram is included as an attachment.The proposed location of
the treatment system and outfall is shown on the attached site plan.
3.2 NON-MUNICIPAL FLOW PROJECTION
Based on similar construction projects in the uptown Charlotte area, the estimated discharge flow
from the treatment system will be 75 GPM(108,000 gpd).

3.3 FEASIBILITY EVALUATION OF ALTERNATIVES
In accordance with 15A NCAC 2H.0105(c)(2), CEC evaluated the technical and economic
feasibility of wastewater disposal alternatives referenced in the Engineering Alternatives Analysis
(EAA)Guidance document.
3.3.1 Connection to Existing Wastewater Treatment System
According to Section 23-79 (b)(14) of the City of Charlotte Sewer Use Ordinance, the municipal
treatment plants owned and operated by the City do not accept groundwater discharges. CEC
inquired about the cost for disposal and treatment of groundwater and DART, a Charlotte-based
company specialized in waste disposal, quoted$0.40 per gallon. Based on the projected flow rate
and anticipated duration of dewatering activities,the disposal cost would be approximately$20.9
million deeming this alternative cost prohibitive.
3.3.2 Land Application and Infiltration Galleries
Due to limited land available adjacent to the project site and setback requirements,land application
and infiltration galleries are technically infeasible as wastewater disposal methods. Nearby
properties are currently valued a $4-10 million per acre making these options cost prohibitive.
3.3.3 In-Situ Remediation Wells
Due to limited land available adjacent to the project site,the installation of off-site injection wells
is technically infeasible as a wastewater disposal method. Nearby properties are currently valued
a$4 -10 million per acre making this option cost prohibitive.
