E, Treatment system influent is groundwater pumped from an area impacted by petroleum hydrocarbons. The influent
rn groundwater is routed through an oil/water separator(OWS)to remove measureable amounts of light non-aqueous
Ephase liquids(LNAPLs).Separated LNAPLs and sludge are collected for offsite disposal or recycling.The groundwater
exits the OWS and passes through bag filters to remove sediment(also disposed offsite)prior to air stripping.After air
;v stripping,the treated groundwater is polished by granular activated carbon prior to being discharged to Outfall 001.A
~ process flow diagram of the preliminary system design is attached.
I Sampling shall be conducted according to sufficiently sensitive test procedures(i.e.,methods)approved under 40 CFR 136 for the analysis of pollutants or pollutant
parameters or required under 40 CFR chapter I,subchapter N or 0.See instructions and 40 CFR 122.21(e)(3).

7.1 Use the space below to expand upon any of the above items.Use this space to provide any information you believe the
reviewer should consider in establishing permit limitations.Attach additional sheets as needed.
Currently,recovered groundwater is stored in frac tanks and disposed of offsite daily. Analytical data for a sample
collected from one of the frac tanks is included to represent the influent to the treatment system.As is typical of initial
carbon filtration usage,the first few equivalent volumes of water to carbon washes away impurities that may be in the
carbon. Therefore,after each initial carbon usage(the filters will be changed several times per year)Colonial will
containerize for offsite disposal the first 3 volumes of groundwater equal to the volume of carbon being rinsed,i.e.
O 4,000 gallons of carbon would be rinsed with 12,000 gallons of stripper treated groundwater prior to resuming
discharge. The rinsate will be stored for offsite disposal. Expended carbon will also be disposed offsite.Air stripping is
known to remove approx.98%of VOCs while the carbon is used to remove most remaining compounds.

Effluent Characteristics Waiver Request
Colonial Pipeline Company — 2020 — L1 — SR2448
14511 Huntersville-Concord Road, Huntersville, North Carolina
DEQ Incident No. 95827
Dear Mr. Denard:
On behalf of Colonial Pipeline Company (CPC), Apex Companies, LLC (Apex) is submitting this
Effluent Characteristics Waiver Request(ECWR) pursuant to Section 4.1 of the NPDES Individual
Permit Application (Permit Application). This ECWR is requested to allow processing of the permit
application as no data for the outfall discharge is available at this time. Once the system
installation is completed, and startup of the treatment system has commenced a representative
sample of the outfall discharge will be collected and analyzed for the Effluent Characteristics
required in Section 4 of the Permit Application. Discharge to the outfall will not occur during
startup sampling. Treated effluent from the treatment system will continue to be containerized
during start up of the treatment system. Discharge to the outfall will not commence without prior
approval from the North Carolina Department of Environmental Quality.
Should you have any questions or comments regarding this ECWR, please feel free to contact
John Strecker at [phone], or Andrew Street at [phone].
Sincerely,
Apex Companies, LLC

ALLOWABLE DISCHARGE DETERMINATION
Permit Application for NPDES individual Permit
Colonial Pipeline Company-2020-L1-SR2448
Huntersville,North Carolina
Determination Criteria Findings DISCHARGE RESTRICTIONS POSSIBLE
Based on the requirements of 15A NCAC 2B.0206(d)(2)there maybe low flow restrictions in the form of water quality based effluent limitations associated
Zero Flow Stream with the proposed discharge to North Prong Clarke Creek. The USGS provided a low flow determination for the proposed discharge location. The data
YES BUT DO NOT APPEAR PROHIBITIVE
Restriction provided indicates no data available at this location,however,using 6 nearby index sites as references 7Q10 and 30Q2 flow data for North Prong Clarke
Creek was implied and is attached.Of the 6 sites referenced,one site had an annual 7Q10 low flow discharge of zero.
North Prong Clarke Creek is classified by the NC DWR as a class C surface water. Class C waters are protected for uses such as secondary recreation,fishing,
Receiving Stream wildlife,fish consumption,aquatic life including propagation,survival and maintenance of biological integrity,and agriculture.Secondary recreation includes ,
Classification Restrictions wading,boating,and other uses involving human body contact with water where such activities take place in an infrequent, unorganized,or incidental YES BUT DO NOT APPEAR PROHIBITIVE
manner.
Basin Wide Water Quality A review of the Yadkin PeeDee River Basin Plan dated 2008 indicates Clarke Creek is an impaired water body due to exceedances for the biological criteria for
Plan fish as a result of stormwater runoff with an overall water quality rating of poor scoring 42 out of 100 for habitat assessment. YES BUT DO NOT APPEAR PROHIBITIVE
Impared water The Draft 2020 303(d)(2) list provided on the NC DWR website lists Clarke Creek as an in impared water body from the source to Rocky River due to
Determination exceedances for the biological criteria for fish. YES BUT DO NOT APPEAR PROHIBITIVE
The Yadkin PeeDee River Basin Plan dated 2008 lists the endangered species within the basin and the waterbodies associated with the endangered species.
Presence of Endangered This Plan does not list any endangered species for the North Prong Clarke Creek. However,the Mecklenburg County Park and Recreation website states that
Species a portion of North Prong Clark Creek is listed as an Elemental Occurrence(EO)as it provides potential habitat for the Carolina Darter which,though not NO
endangered,is listed as a North Carolina Special Concern Species.

ALTERNATIVE NUMBER ALTERNATIVE NAME ALTERNATIVE DESCRIPTION FEASIBILITY SUMMARY 10-YEAR PRESENT VALUE COST1
There are two potential connections to the sanitary sewer from the proposed Groundwater Remediation
Treatment System location.The first connection is an 18-inch pipe located northeast of the proposed
Groundwater Remediation Treatment System.The second connection is an 8-inch pipe located southwest
of the Groundwater Remediation Treatment System(Figure 3).
During a January 26,2021 phone call with Bill Gintert,Environmental Compliance Manager with Charlotte
Connection and discharge of groundwater to Water,Apex was informed the City of Charlotte Sewer Use Ordinance Section 23-79(b)(14)directly 2
1 Sanitary Sewer Discharge sanitary sewer for treatment at local Publicly prohibits the discharge of groundwater unless specifically authorized. $225,000-$518,000 '3
Owned Treatment System(POTW)
Based on the call with Mr.Gintert this option is not feasible.
Per review of the Charlotte Water FY21 Water&Sewer Rates and Fees,the cost to discharge treated
groundwater to the sanitary sewer under the IWC-Industrial Waste Charge category is$0.27 per 100 cubic
feet($0.27 per 748 gallons).
The minimum daily recovered groundwater is anticipated to be greater than 250,000 gallons per day.The
Land application of groundwater discharge northern portion of the site(north of Huntersville-Concord Road)is a nature preserve that does not require
irrigation.The southern portion of the site(south of Huntersville-Concord Road)is zoned for residential

irrigation,and spray irrigation.
Groundwater discharge for land application is not feasible.
Based on a minimum treated groundwater flow rate of 250,000 gallons per day,infiltration rate of 0.3
gallons per day per square foot(in accordance with 15A NCAC 18A.1955 Design Installation Criteria for
Conventional Sewage Systems),and a factor of safety equal to 2,the estimated surface area for infiltration
3 Infiltration Galleries Groundwater discharge to infiltration galleries Not Applicable
is approximately 38 acres.
Groundwater discharge to infliltration galleries is not feasible.
In addition to the groundwater recovery well network installed at the site, air sparge wells and a soil vapor
extraction(SVE)system are being installed. The air sparge wells and SVE system will decrease the
migration of dissolved phase hydrocarbons south of the release area and recovery well network.Once
complete,a total of 22 air sparge wells and 18 soil vapor extraction wells will have been installed.Vapor
recovered from soil vapor extraction wells will be routed through a temporary thermal oxidation unit.
Trailer and skid mounted air sparge and SVE equipment will be utilized as an interim remedial measure
until permanent air sparge and SVE equipment can be installed(following NCDEQ approval of the CAP for
Incident No.95827).
4 In-Situ Groundwater Groundwater discharge to in-situ Additionally,once completed,a total of 69 vacuum enhanced recovery wells and 56 hydraulic control wells
Remediation Wellsgroundwater remediation wells will have been installed within the release area.Pneumatic recoveryNot Applicable
pumps have been placed in the wells
and vacuum is applied to the wells to enhance recovery.As of July 8,2021,approximately 1,107,192
gallons of free product gasoline and approximately 2,521,063 gallons of petroleum contact water have
been recovered from the recovery well network.
Additional recovery wells may be added in the future to expand the recovery well network if needed. The
goal of the long term operation of the recovery wells is to create a hydraulic barrier to prevent free product
and VOCs from migrating further downgradient from the initial release location.
Groundwater discharge to in-situ remediation wells is not feasible.
As described above,the goal of the long term operation of the recovery wells is to create a hydraulic

Groundwater discharge to closed loop remediation wells is not feasible.
NOTES:
1.10-year present value cost assumes a discount rate of 7%
2.Estimated costs assume discharge rate between 250,000-576,000 gallons per day and discharge fee of$0.27 per 748 gallons for sanitary sewer option.
3.Estimated costs do not include plumbing permit fees,utility permit fees,or installation of underground discharge piping from the proposed location of the Groundwater Remediation Treatment System to the sanitary sewer location.
