FINDINGS AND CONCLUSIONS
Based on the economic evaluation of land application alternatives, the use of injection,
GEQSCIENCE closed -loop, or in -situ groundwater remediation technologies (as previously mentioned in
GROUP our April 18, 2007 NPDES permit application) are considered technologically infeasible
since the subject site will require permanent dewatering. Additional land would need to b
purchased for offsite placement of injections wells in order liar either of the land application
alternatives to become a viable option. Given the cost for land acquisition ($ ,000,000) a
well as other constraints (highly urbanized area); these technologies are also considered to
be economically infeasible.
s previously mentioned, the estimated cost to implement the proposed de watering
system and its associated remedial system components is expected to be approximately
$150 000 and the projected yearly O&M cast is anticipated to be approximately $34,700.
Assuming a capital cast of $150,0 0, an annual recurring cost o $34,700, and an EPA
discount rate of 5. 78%, the 20-year present value cost for the dewatering system is
expected to be $552,5 0 in comparison to $5,631,820, $5, i01,520, and $5,594,520 for
closed -loop injection, drip irrigation and spray irrigation systems, respectively.
Based upon present value cost analyses, the proposed direct discharge to the Dairy
Branch of Little Sugar Creek (as outlined in our April 2007 NPDES-permit application) is
still considered to be the most economically feasible and best available technology for
wastewater disposal. 'Thus, Cleoscience respectfully requests that a NPDES permit be
granted by the DWQ for direct discharge to the :Dairy Branch.

Historical groundwater level measurement data collected from the site indicates that the depth to
groundwater varies across the site and ranges between approximately 15 feet below ground surface
(bgs); in the high areas of the site to approximately 7 feet'bgs in the low areas. Finished subgrades of
the proposed parking deck will extend approximately 30 feet below the existing ground surface (or
15 feet below the groundwater table in the high areas of the site). Based on the findings of previous
investigations performed at the site, dissolved petroleum' hydrocarbons and chlorinated solvents have
been detected in the groundwater at levels exceeding the 15A NCAC 2L Groundwater Standards.
The primary hydrocarbon constituents that have been historically detected in the groundwater at
levels above their applicable 2L standards include benzene and naphthalene. However, recent
groundwater quality data reveals that total xylenes currently exceed its applicable 2L standard.
Chlorinated solvents historically and currently detected in the groundwater above their applicable 2L
standard include tetrachloroethene, trichloroethene, bi(-ethylhexly)phthalene, and 1,-
dichloroethane. ' Additionally, the constituent chloroform has historicallybeen detected at levels
exceeding its applicable 2L standard; however, recent groundwater quality data dries not indicate the ,
presence of this constituent. None of the dissolved hydrocarbon and/or chlorinated solvent
constituents have exceeded gross Contaminant Levels. The source of the dissolved hydrocarbon
constituents is expected to be from an underground storage tank (UST) system that was previously
located at the subject site. The source of chlorinated solvents is unknown.

As part of the proposed development, a permanent dewatering system will be installed during pre
construction activities and incorporated into the final design of the development to continuously
remove groundwater from the subject site. In an effort to effectively remediate the hydrocarbons and
chlorinated solvents in the groundwater, an activated carbon filtration system will be incorporated

into the dewatering system design to reduce contaminant levels to NC'DENR-acceptable levels prior
to offiite discharge.
Based upon an evaluation of wastewater disposal alternatives (as discussed herein), BlueSky
proposes to direct treated groundwater (effluent) from the dewatering :system to the City of Charlotte
storm sewer system via an on -site outfall (Outfall 001). Treated effluent within the storm sewer
system will be directed and discharged into the Dairy Branch (DWQ Stream index No. I 1-17-5-1)
which, in turn, ultimately discharges to the Little Sugar Creek (DWQ Stream Index No. 11-137- ).
The method selected for wastewater disposal (direct discharge) is expected to be the most
technologically feasible and cost effective of each alternative considered. used upon the proposed
design, the dewatering; system will discharge approximately 50,000 gallons per day of treated
effluent into the city -owned storin sewer system. The system will be designed `` to operate
continuously and unattended. Cleanup levels applicable to the wastewater discharge will be the 1 SA
NCAC 2B Surface water Quality Standards.
Restrictions Prohibiting the Proposed Discharge
There are no zero -flaw stream restrictions, population and flow limitations, receiving; stream
classification restrictions, endangered species, and/or Basinwide Water Quality Plans that would
preclude the discharge of treated effluent from the proposed dewatering system to the Dairy Branch.
The proposed action (i.e. construction of the dewatering system and its associated remedial
appurtenances) is consistent with local subdivision and zoning; regulations and does not violate any
ordinances.Discharge from the proposed dewatering system will begin upon approval and issuance
ofaNPDES permit.

INTRODUCTION
Purpose
The purpose of this EAA is to evaluate technologically feasible alternatives for wastewater disposal
and to present the means by which impacted groundwater will be remediated to acceptable levels
prior to discharge under an approved NPDES perrmt. This' EAA has been prepared' in general
accordance with 15A NCAC 214.0105(c)(2) and the North Carolina Division of rater Quality
(DWQ) Engineering Alternative Analysis Guidance document, dated ".tune 23, 2005. The
engineering analysis presents a brief summary of the project background and provides an evaluation
of technologically feasible engineering alternatives for wastewater disposal. The EAA also provides
flow projections and an estimated cast for the wastewater disposal alternative selected. A list of
governmental agencies contacted in preparation of this EEA document is provided in Appendix IL
As required by the DWQ, an executed and notarized copy of the Local Government Review Form is
included in Appendix III. The sources referenced are provided' in Appendix Vill.
Project Background
The subject property is located at 2525 South .Boulevard in Charlotte, North Carolina. As depicted
on the Site Vicinity Map included as Figure CH039-1 (Appendix I), the site is situated along the
eastern side of South Boulevard at its intersection with Ideal Way. The subject property is currently
developed with a vacant single -story building that was previously utilized as an automotive repair
facility. Blky Partners, LLC (BluSky) is proposing to redevelop the property with a mixed use
development consisting of -hundred (00) residential dwelling units and approximately 15000-
square feet of commercial office, retail, and restaurant space. ' The proposed development will also
include a multi -level underground parking; deck that will extend approximately 30 feet below the
existing grade. A United States Geological Survey (USGS) topographic reap which depicts the
location of the site is also included in Appendix I as Figure C 03 -2.
Site and Vicinity Characteristics
The proposed development is comprised of an approximate ±L2 acre land parcel and is situated
within a highly urbanized area of the City of Charlotte. Properties immediately surrounding the site
consist of residential, retail and commercial interests. As depicted in Figures Ch 39-1 and CH039-
2, the property is bordered south, east, and west by Ideal Way, Euclid Avenue, and South Boulevard
(respectively). Residential properties are located further east of Euclid Avenue. However,
commercial and retail properties are located immediately north of the site and beyond Ideal Wary and
South Boulevard:
Regionally, the subject site is located within the Charlotte Belt of the Piedmont Physiographi
Province, which hydrologically, encompasses the Catawba River Subasin (03-08-34) The
topography of the property slopes regionally east towards Little Sugar Creek. however, locally, the
site slopes southeast towards the Dairy Branch, which is a drainage tributary of Little Sugar Creek.
Current site elevations range between approximately 718 to 732 feet above mean sea.. level (MSL), with
the high elevation of 72 feet MSL, present in the north-northwest portion of the site and the low
elevation of 718 feet ML present in the southeastern portion of the property, historical groundwater
level measurements collected from the site indicates that the depth to groundwater varies across the

site and ranges between approximately 15 feet below ground surface (bgs) in the high areas of the
site to 7 feet bgs in the low areas.
Basis for Requesting a NPDES Permit
Given that finished subgrades of the proposed parking deck will extend approximately 30 feet below
the existing ground surface for 15 feet below the groundwater table in the high areas of the site), a
permanent dewatering system will be installed and incorporated into the final design of the
development to remove groundwater from the site. {liven the presence of petroleum hydrocarbons
and chlorinated solvents in the groundwater at levels exceeding the 1A NCAC 2L Groundwater
Standards, an activated carbon filtration system will also be incorporated into the design of the
dewatering system to treat contaminants prior to discharge.
The primary hydrocarbon constituents and their maximum concentrations detected are provided in
Table 1 (Appendix 1). Additionally, chlorinated solvents that have been detected at the site (along
with 'their maximum detectable concentrations) are also provided in Table 1; As shown, the primary
hydrocarbon constituents that have been detected in the groundwater above their applicable 21..
standards include benzene and naphthalene. Chlorinated solvents detected above the applicable 21,
standard include tetrachloroethene, tr°ichloroethene, bis(2-ethylhexly)phthalene, ; and 1,-
dichloroethane. Additionally, chloroform has historically been detected in the groundwater-
exceeding its applicable 2L standard although recent groundwater duality did not indicate the
presence of this contaminant. None of the dissolved constituents have exceeded their Gross
Contaminant Levels. The source of the petroleum hydrocarbons is likely fiom underground storage
tanks that were previously located on -site and removed during tank closure activities in December
2003 and April 2004. The source of the chlorinated solvent release is unknown,

DESIGN SPECIFICATIONS.AN FLAW PROJECTIONS
The objective of the proposed dewater system (and its associated remedial appurtenances) will be to
1) dewater the site in the vicinity of the below grade parking deck and 2) to reduce dissolved
hydrocarbons and chlorinated solvent concentrations to NCDENR-acceptable levels prier to offsite
discharge. The following subsections provide detail with respect to the design of the dewatering
system; its estimated/projected flows (based on engineering design considerations); and the
clean-up objectives of the proposed system.
System Design and Process
Preliminary design of the proposed dewaternglremediation system will include eighteen (18) vertical
groundwater recovery wells (RW-1 through RW-18) that will be connected by manifold to a 15-Hp
vacuum pump. These units are designed to provide quiet pumping operations where noise must be
kept to a minimum. The proposedlayout of the dewaterinl lremediation sy tern is Illustrated in
Figure CH039-3 (Appendix I). As shown in this drawing, each of the proposed recovery wells will
be installed (at approximately 30 to 35 foot centers) along the boundaries of the proposed
development to dewater the site during pre- and post -construction activities. The location of the
dewatering wells was selected to maximize drawdown potential and increase the radius of influence
of groundwater recovery within the proposed construction area. Figure CH039-4 illustrates the
process and instrumentation of the proposed dewateringlretnediation system. The approximate
location of proposed Outfall 001 are depicted on Figures CH039-2 and C'H0-3. The location of
the proposed discharge stream (Dairy Branch) is depicted on Figure CH039-2.
As shown in Figure CH }39-5 each of the recovery wells (RW-I through RW-18) will be completed
to depths of approximately 60 feet below ground surface (bgs) and will be constructed rising 4-inch
diameter, schedule 40 PVC pipe and approximately 50 feet of 0.010-inch machine -slotted screen.
Each of the recovery wells will be connected to a 6-inch diameter, schedule 40 PVC manifold pipe -
(header) which, in turn, will be connected to the vacuum pump inlet. Note that initial design of the
dewatering system will be such that recovery wellheads and the 6-inch header pipe will be located ,
above grade during on -site construction activities; however, final design of the system will require
that each wellhead and the common header be buried within atwo-foot deep trench leading from the
dewatering system compound to the recovery wells. Each trench will be backfilled with compacted
soil and completed to match the design specifications of the proposed development. The dewatering'
system compound will be located in the southeast corner of the development (Figure CH039-) on
the first floor of the below -grade parking deck. As depicted in Figure CH39-, each recovery well
will be completed with a concrete vault and 8-inch manhole cover to allow access to on -site wells.
Additionally, as shown in Figures CH039-4 and CH039-5 ball valves will be installed at each
recovery wellhead to enable manual adjustment of the vacuum pressures and groundwater flow rates.
Proposed Vacuum Pump Unit
A 20-Hp, explosion proof, vacuum pump (Griffin Silent Pac or similar unit) will be utilized to
creative negative pressures at the eighteen groundwater recovery wells. The vacuum will operate on
3-phase, 208I230-volts; 60 hertz, and 26 amps. Given the residential use of the proposed
development, the vacuum pump shall be operated within OSHA noise standards. Additionally, the
vacuum unit will be equipped with the following that will be mounted onto a concrete pad within the
dewatering system compound: an 80-gallon moisture separator with liquid level sensors and auto

drains, explosion -proof motor starter, totally enclosed fan cooled (TER") motor, fail safe circuitry,
vacuum pressure and flow gauges, a vacuum safety relief valve, a then-nal overload switch, and an
exhaust silencer. The dewatering system will be designed to operate continuously and unattended.
Automatic shut -dawn of the vacuum pumping unit would occur if any of the following conditions
develop. high temperature in the exhaust due to motor overload, thermal overload, or excessive
vacuum at flow rates beyond the design of the system.
Proposed Remediation finite
As shown in the Process and Instrumentation Diagram (Figure C1303 4) developed for the
dewatering system, two (2) 50 -gallon activated carbon filtration units will be installed in -series with
the dewatering system to treat dissolved hydrocarbons and chlorinated solvents in the groundwater.
Following activated carbon treatment, groundwater will be directed to a 2 00-gallon holding; tank
that will temporarily stare the treated effluent and allow suspended solids to settle out prior to
discharge to the City of Charlotte stonn system. The holding tank will be equipped with a high level
shutoff sensor and drainage valve that will direct treated effluent, via a 4-inch PVC" pipe (Figure
CH03 -3), to the on -site discharge point (C utfall 001). The 4-inch drain pipe will be equipped with
a sample part to allow direct sampling of the treated effluent prior to offsite discharge In addition,
the drain pipe will also be equipped with a flow meter (Figure CH03 -4) to measure wastewater
volumes`discharged to the storm sewer. The analytical results of effluent samples will be reported to
the D WQ can a quarterly basis or as required by the State under an approved NPI ES permit.
Dewatering system flow will also be reported as required under the NPDES permit.
Projected Flow Volumes
An important design consideration of the dewatering system is the subsurface geology. Based
Upon geotechnical borings completed at the subject site, subsurface soils are generally comprised
of sandy clayey silt to depths of approximately 17 feet below ground surface (bgs): At depths
greater than 17 feet b, the soils become sandy silts to depths of about 42 feet bgs. Below 42
feet bgs, the soil is comprised of silty sand to depths of approximately 71 (termination of
geotechnical boring). According to Cherry and Freeze, et al., the saturated hydraulic
conductivity of silty sand soils is expected to range between 10-3 to 10-5 centimeters per second
(cm/sec). Thus, assuming an effective porosity of 0.15, yields from groundwater recovery wells
installed within this medium would theoretically be 2,280 gallons per day (gpd).
The dewatering system will operate continuously at pumping rates ranging between. 25 to 30
gallons per minute (at the vacuum pump inlet/outlet) and I to 2 gpm (at each well head). Initial
dewatering of the site will likely require higher pupping rates and produce higher volumes of
wastewater. l~Iowever, as the system equilibrates, much lower volumes of wastewater will be
produced, Lower vacuum levels and flow rates at each wellhead will be achieved by reducing
the pumping rate at the vacuum unitand/or closing wellhead ball valves. The maximum
groundwater flow capacity of the 20-Hp vacuum pump is 1,500 gallons per minute (gpm).
Based on the aforementioned flows rates (24 to 30 gpm), the proposed dewatering system is
expected to discharge approximately 40,000 to 50,000-gallons per day gpd) of treated
groundwater into the city storm, sewer system.

an -Up Objectives
objective of the proposed renediation system (i.e. activated carbon units) that will be
nrporated into ` the clewatering system design will be to reduce dissolved hydrocarbons and
)rmated solvent concentrations in the groundwater prior to discharge to the city -owned store
er system. Coven that the proposed dewateringltreatment system will discharge to the Daily

orically detected above their applicable 2L standard include tetrachloroethene (PCE)
,iloroethene ('CE), bis(2-ethylh xly)phthalene, and 1,2-dichloroethane, In addition, the
stituent chloroforrn has historically been detected in the groundwater at levels exceeding its
livable 2L standard. None of the dissolved hydrocarbon and/or chlorinated solvent constituents

Based on recent groundwater quality data (March 2047), dissolved hydrocarbons and chlorinated
solvents are stir present in the groundwater beneath the site (Table 2, The primary
hydrocarbon constituents currently detected in the groundwater included total xylenes,
However, this contaminant did not exceed its applicable 2L groundwater standard. Chlorinated
solvents currently detected in the groundwater above their applicable 2L standard still include P'CE
TCE, bis(2-ethylhexly) hthalene, and 1,-dichloroethane. No phenolswere detected in the
groundwater. However, lead was recently detected at a concentration below its applicable 2L
standard. None of the dissolved hydrocarbon and/or chlorinated solvent constituents currently
exceed their applicable GCLs.. Additionally, none of the contaminants exceed their applicable
surface water standard (Table 2). Documentation from. the March 2007 sampling event (including
copies of the laboratory datasheets and chain -of -custody fo ) is provided in Appendix V of this
FAA document.

EVALUATION OF TECHNOLOGICALLY FEASIBLE ALTERNATIVES
As required by the DWQ, several wastewater disposal alternatives were evaluated for use at the
Subject site in an effort to minimize or eliminate the proposed point source discharge to the Dairy
Branch. The wastewater disposal alternatives considered for use during preparation of this EAA
are listed below. Each disposal method considered was evaluated based upon its feasibility,
innplementability, and cost. A detailed discussion of each alternative is also provided below.
• Connection to an Existing Wastewater Treatment Plant,
• Land Application Alternatives;
• Infiltration galleries;
• Injection, Closed -Loop, andIn-Situ Wells;
• Wastewater Reuse,
• Direct Discharge to Surface Waters; and
• Combination of Alternative
Connection to an Existing Wastewater Treatment Plant
Connection to an existing public or private wastewater treatment plant is considered
technologically infeasible. There are no private wastewater treatment plants or associated sewer
lines in the immediate vicinity of the proposed development or within a -mile radius of the
subject site. Based on information provided by the Charlotte-Ivleekleznburg Utilities Department
(C1VI:tD), Section 23-7(14) of the City of Charlotte Sewer Use Ordinance (SU) strictly
prohibits the discharge of groundwater into its sanitary sewer system. Thus, connection to a
public wastewater treatment plant and its associated sanitary sewer lines would not be a feasible
option for use at the property. Correspondence from C MUD (dated April 9, 2007) documenting
non -acceptance of wastewater generated on -site is ;provided in Appendix 'VI.
Land Application Alternatives
-
Land application, as a wastewater disposal alternative, is not considered feasible based upon land
constraints within the city.
Infiltration galleries
Infiltration galleries are considered technologically infeasible due to land constraints within the
city.
Injection, Closed -Loop, andIn-situ Groundwater Remediatiou Well
The use of injection wells is considered technologically infeasible given the highly urbanized
development of the area: and land constraints. In addition, the use of closed -loop and/or in -situ
groundwater remdiation wells is considered technologically infeasible given that the site will
rewire permanent dewatering. The proposed development will be situated on an approximate

1.2± acre land parcel that is located within a mixed commercial and residential area of the City
of Charlotte. As such, no land is available for offsite placement of injection wells.
Wastewater Reuse
Reuse of all or a portion of the wastewater generated by the proposed dewateringlremediatican
system was evaluated as a disposal alternative for the subject property: Given its design and
urban location (uptown Charlotte), the proposed development will have limited landscaped areas
associated with the property. The entire site will be covered with concrete, asphalt -paved
parking areas, access roads, and other impervious surfaces, As such, reuse of all or a portion of
the wastewater for irrigation purposes is not considered technologically feasible.
Additionally, given the residential nature of the development and the potential for accidental
ingestion by residents, reuse of wastewater in the restrooms of residential emits aiadlcar
commercial spaces of the property (i.e. commodes) is not considered feasible. Furthermore, as
mentioned previously, the City of: Charlotte Sewer Use Ordinance prohibits the discharge of
groundwater to its sanitary sewer systems eitherdirectly or indirectly. As such; wastewater from
the dewatering systemcannot be redirected to on -site commodes and discharged into the city
sanitary sewer lines as this scenario constituents an indirect discharge.
Direct Discharge to Surface Waters
Based upon evaluation of wastewater disposal alternatives, direct discharge to a surface
waterbody under the NPDES program is considered to be the most technologically feasible
option for use at the subject property. As previously mentioned, BlueSky is proposing to
discharge treated effluent from on -site dewatering system to the Dairy Branch of Little Sugar
Creek. Discharge to the Dairy Branch will be accomplished via an on -site outfall that will direct
wastewater• to the City of Charlotte storm sewer system. As detailed in the FLOW
PROJECTIONS section of this EEA, the maximum daily load that will be discharged from the
dewatering system into the storm system is estimated to be approximately fifty -thousand
(50,000) gallons per day (gpd). Based upon design specifications of the city storm sewer system,
the storan pipelines at the proposed discharge point (Outfall 001) are capable of handling the
added volume of wastewater. As mentioned previously, a site plan which depicts the proposed
layout of the dewatering system and location of Outfall 001 is included in Appendix I as Figure
CH039-3. A schematic diagram of the system and its major components is provided as Figure
CHE - (Appendix I).
Based on information provided by the United States Geological Survey (USG) — Raleigh
Office, summer 7 10 and 30Q2 flaw data for the receiving stream (Dairy Branch) is estimated
to be less than 0.01 cubic feet per second (efs) and 0.16 cfs, respectively. Given the extremely
small magnitude of these flows, the USGS concludes that the Dairy Branch likely has zero flow.
However, a review of records maintained by the DQ for waterbodies within Mecklenburg
County did not reveal that the Dairy Branch has any zero -flaw stream restrictions. According to
15A NCAC 2B.0206(d)(2), the State has imposed restrictions that apply to oxygen -consuming
waste discharged to zero -flaw streams. However, no oxygen -consuming materials will be
utilized in the dewatering and/or remediation system processes and, as such; no oxygen-

consurning,wastes will be ;generated from on -site operations. Appendix VII of this IAA
document contains a copy of the streamflow data: and calculations provided by the USCS.
According to the D Q Classifications and Standards -Unit (CSU) as well as a report of North
Carolina Waterbodies Listed by County (dated February 26,.2007) the "wiry Branch and Little
Sugar Creep have been classified as `Class C" surface waters. Based on information provided on
the CSIJ website, these surface waters have no restrictions on watershed development or types of
discharges. No additional and/or supplemental stream classifications have been assigned to the
proposed discharge stream(s) that would preclude the proposed discharge. A copy of the February
2007 county waterbodies report is provided in Appendix IV.
According to the Basinwide Planning Unit, water quality plans have been implemented to
improve the water duality of the Dairy Branch and Little Sugar Creek. However, current plan
for these surface waters do not prohibit the proposed wastewater discharge. Review of the DWQ
)03(d) list (Appendix IV) reveals that the Dairy Branch is not listed as a 303(d) inrp Tired'
waterbody. However, further review of the 30(d) list indicates that Little Sugar- Creek is a
unpaired waterbody. Based on information provided by the DWQ`- Total Maximum Daily Load
(TMDL) Unit, Little Sugar Creels has TMDL restrictions imposed for fecal conform and
turbidity. However, the proposed wastewater discharge will not contain any fecal coliforill. In
addition, given the design of the dewatering system, turbidity of the discharge is expected to be
minimal. No other TMDL restrictions have been or will be imposed on Little Sugar Creek that
would preclude discharge of the proposed wastewater". Thus, the proposed discharge should b
allowed and a NPDES permit granted.
1
According to the NCDENR Natural Heritage Program, no endangered species are present within
the proposed discharge location. As such, no restrictions relative to the presence of endangered
species have been imposed by Federal and/or State agencies that would prohibit the proposed
discharge. Documentation from the Natural Heritage Program (dated March 19, 2007) is
provided in Appendix IV of this EA document.
With the exception of low -flow or zero flow conditions, there are no restrictions that would
preclude the discharge of wastewater from the subject site. The dewatering/remediation system
will be design in a manner to eliminateand/or reduce dissolved hydrocarbons and chlorinated
I solvents prior to discharge to the Dairy Branch. Based on historical groundwater quality data
compiled (Table I - Appendix V), the primary dissolved hydrocarbons detected in the
groundwater above the 15A N AC 2L Groundwater Standard included benzene and
naphthalene. Chlorinated solvents historically detected above their applicable 2L standards
included tetrachloroethene (PCE), trichloroethene (TCE), bis(2-etlhel)phthalene, chlorofonn,
and 1,2-dichloroethane. No phenolic compounds have detected in the groundwater at the subject site.
Additionally no lead has been historically detected on -site. Table 1 also provides a summary of each
contaminant detected at the subject site, along with the maximum concentration reported for each
compound. As depicted, none of the detectable constituents have exceeded Cross Contaminant
Levels established for each compound. Additionally, none of the contaminants have exceeded their
applicable 1A NCAC 2B Surface Water Quality Standards.

As shown in Table 2 (Appendix 1), recent groundwater duality data for the subject site indicates
that the primary dissolved hydrocarbon constituent currently present in the groundwater is total
xylenes. However, this contaminant does not exceed its applicable 2L groundwater standard.
Chlorinated solvents currently present in the groundwater above their applicable 2L standards
include PC , TCE, 1,2-dichloroethane, and bis(2-ethylbexly) hthalene. Dissolved lead was also
detected in the groundwater but at concentrations which did not exceed its applicable 2L standard
(Table 2). to phenols were detected in the groundwater.
Combination of Alternatives
A con-abination of the above -previously discussed wastewater disposal alternatives was evaluated
as part of this EAA in an effort to minimize or eliminate the proposed discharge to the Dairy
Branch. Given the current land constraints, the only combination of disposal alternatives that
could be possibly considered for use at the subject property included the reuse of wastewater in
conjunction with direct discharge to the Dairy Branch under the NP ES program. However,
given the urban setting of the proposed development (uptown Charlotte), there are limited
landscaped areas associated with the property.; Thus; reuse of wastewater solely for irrigation
purposes (as mentioned previously) or in conjunction with another wastewater disposal ,
alternative (such as direct discharge) is considered infeasible.
Selected Method of Wastewater Disposal
The method selected for wastewater disposal at the subject site is the direct discharge of
wastewater into the laity Branch. This method is deemed the most technologically feasible for
use at the site.

ECONOMIC .FEAS1 LITY OF AL I'Eli NA TI VE.
As required by the DWQ, a Present Value Cost Analysis (PVCA) for a 20-year planning period
was performed for each wastewater disposal alternative identified as technologically feasible;
Given the current land constraints and local ordinances prohibiting connection and/or discharges
to city -owned P}TWs the only wastewater disposal alterative identified as technologically
feasible is the direct discharge of wastewater to a surface waterbody (Dairy Branch) under an
approved NPDES permit, As such:, a 20-year PVCA was only performed for this wastewater
disposal scenario. All costs provided are based upon vendor quotes and past experiences at
similar sites. Given that annual casts for operation and maintenance -(O&M) is expected to
remain relatively the same over the 20-year planning period, the following standard formula was
used to calculate the present value for direct discharge wastewater disposal:
r(�+rlrl
Where:
PV — Present value of cost
Co - Costs incurred in the present year
C Recurring cost
n = Ending year of the life of the facility
r Current EPA discount rate (as obtained from North Carolina Construction Grants
and Loans (NC GL) website http:/www.nccgl.net/fap/ cwsrf/ 01 ui.html)
Based on vendor quotes, the estimated total cost to implement the proposed dewatermia system
and its associated remedial system components is expected to be approximately $150,000. A
breakdown of cost is as follows. (1) Professional supervision of labor, system design and bid;-
project management, and scheduling - $18,000, () drill/install eighteen groundwater recovery
well points - $32,000 () trenching and piping of the dewatering system vacuum lines —
$40,000, () installation of dewatering system compound and remedial equipment (i.e. vacuum
pump, carbon units, and air stripper) - $30,000, (5) purchase of 20.11p vacuum unit with controls
- $15,000, '(6) installation of vacuum controls in dewatering system compound - $2,5, (7)
electrical wiring and permits - $10,000, and (8) start-up - $2,500.
The projected yearly O&M cost of the dewatering/remediation system is estimated to be
approximately $ 4,7 0, and is based upon the following: Operator Expenses ($10, 00), O&M
Expenses ($6,000), Carbon Disposal ($4,000), Permitting/Compliance ($5,000), Utility Fees
($,000), and Laboratory Fees ($3,700) assuming a weekly monitoring regime, as requested by
the DWQ.

PVCA for Direct Discharge to Surface Waters
Assuming capital cast (Co) of $150,000, an annual recurring cost "(C) of $34,700, and an EIIA
discount rate (r) of 5,8 8% (as obtained from the 1 CCGL website), the 20-year (n 20) present
value cost is expected to be $552,520, PVCA computations for the dewat ring system are
provided in Appendix VIII.

Dear Mr. Johnson:
The Natural Heritage Program has no record of rare species,, significant natural communities, or
significant natural heritage areas at the site nor within a mile of the project area. Although our maps do
not show records of such natural heritage elements in the project area, it does not necessarily mean that
they are not present. It may simply mean that the area has not been surveyed. The use of Natural
Heritage Program data should not be substituted for actual field surveys, particularly if the project area
contains suitable habitat for rare species, significant natural communities, or priority natural areas.
You may wish to check the Natural Heritage Program database website at ,w.ncnhp.org for a listing of
rare plants and animals and significant natural communities in the county and on the quad map.
NC OneMap now provides digital Natural Heritage data online for free. This service provides site
specific information on GIS layers with Natural Heritage Program rare species occurrences and
Significant Natural Heritage Areas. The NC OneMap website provides Element Occurrence (E J) ID
numbers (instead of species name), and the data user is then encouraged to contact the Natural Heritage
'Program for detailed information. This service allows the user to quickly and efficiently get site specific
NHP data without visiting the NHP workroom or waiting for the lnforination Request to be answered by
NHP staff. For more information about data formats and access, visit <www.nconemap.comldata.html>,
or email NC OneMap at <dataq�7a ncmail.net> .
Please do not hesitate to contact me at 919-71-8697 if you have questions or need further information.
Sincerely;
{
