Beginning no later than 270 days from the effective date of this permit, the permittee shall
begin reporting discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month
and submitted electronically using eDMR. The eDMR system allows permitted facilities to
enter monitoring data and submit DMRs electronically using the internet. Until such time
that the state's eDMR application is compliant with EPA!s Cross -Media Electronic Reporting
Regulation (CROMERR), permittees will be required to submit all discharge monitoring data
to the state electronically using eDMR and will be required to complete the eDMR submission
by printing, signing, and submitting one signed original and a copy of the computer -printed
eDMR to the following address:
NC DENR / Division of Water Resources / Information Processing Unit

If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,
1. 1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be
submitted to the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the
date the facility would be required under this permit to begin using eDMR. Temporary
waivers shall be valid for twelve (12) months and shall thereupon expire. At such time, DMRs
shall be submitted electronically toi the Division unless the permittee re -applies for and is
granted a new temporary waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic
reporting requirements is found on the following web page:
'tjLt,jLj/ponat,pc(Lcpr orghyet)4K ptp/ho -g/edmr
L _ _ yq4�jft __ _g/jp -.—
Regardless of the submission method, the first DMR is due on the last day of the month

I have only one minor comment on the draft permit. The units of measurement for total suspended solids should be
changed from ug/L to m/L; annoying cut/paste errors.
Also Jeff' Mitchell has moved on from Mecklenburg County. Richard Farmer is the new supervisor overseeing NPDES

sample collected over a 24-hour period by continuous sampling or combining grab samples of at least"100 l in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the followingmethods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of`flow.
(2) Constant time/variable volume- a series of grain samples collected at equal time intervals over a 24 hour-
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a:series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement' between sample intervals shall be determined by use of a flow recorder and

RE: AquAir NPDES Renewal Permitting Section
Dear Wren;
On behalf of Westinghouse Real Estate, LLC, Shield Engineering, Inc. (Shield) is herein requesting a
renewal of the above referenced. National Pollutant Discharge Elimination System (NPDES) permit.
Attached are one signed original and two copies of the completed NPDES Permit Application Short
Form C - GW.
The groundwater treatment system has been turned off since August, 2011 and has not been discharging
sine that time. The other change at the facility is that the owners have a new name, Westinghouse Real
:Estate, LLC instead of SNI, Corporation.
Shield has been delegated authority to prepare the renewal package by Westinghouse Real Estate, LLC
as shown by the signature below of Peter Gilchrist representing Westinghouse Real Estate, LLC.
When operating, the only solids generated are spent carbon and falter bags. The spent carbon would be
picked up and recycled by a company licensed to replace carbon.The filter bags were air dried and then
disposed of as a municipal waste.
This is a non -industrial facility so no priority pollutant analysis is warranted.
We would like to renew the NPDES permit but keep it inactive should we ever re -start the groundwater
treatment system,
Sincerely,,
Shield Engineering Inc.

Dear Mr. Gilchrist:
Enclosed with this letter is a copy of the draft permit for your facility. Pleasereview the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from your current permit:
A Reasonable Potential Analysis (RPA) was performed on data submitted by the facility from
December 2000 through September 2004 to determine the need in maintaining permit limits and
monitoring for particular effluent characteristics. As a result of the RPA, monitoring has been
eliminated in the draft for 18 of the 23 parameters found in the existing permit.
Please submit any comments to me no later than thirty days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of the page. If no adverse comments, are
received from the public or from you, this permit will likely be issued in May 2005, with an effective date
of July 1, 2005.
If you have any questions or comments concerning this draft permit, call me at [phone],
extension 547.

Possible toxic impacts to surface waters: The groundwater to be recovered and
treated at the site is contaminated with several chemicals for which the Division
has surface water standards. Specifically, the following chemicals have been
detected in
monitoring wells at the site:

The groundwater is contaminated with other chemicals for which the Division
does not have a surface water standard. The modeling presented by the applicant
indicates that the air strippers will be capable of reducing the chemical
concentrations of the wastewater to acceptable levels before discharge to the

PART ITV - EVALUATION AND COMMENDA'TIONS
The applicant is requesting a permit to discharge treated groundwater at the subject site.
The contaminant concentrations in the groundwater significantly exceed state groundwater
standards for several compounds. Based on monitoring well sample results provided by the
applicant, the groundwater contaminant plurne has extended into the bedrock aquifer. {once in
bedrock, groundwater contamination can migrateigreat distances in unknown directions with
unknownconsequences. Therefore, the contamination should be treated and hydraulically
controlled.
This Office recommends issuing a discharge permit to the applicant requested.. The
following suggestions are provided for your consideration.
1 This Office recommends installing a coarse particle filter (grit remover) before the air
stripper. Without one, the carbon in the polishing tank may be spent more quickly thus
necessitating more frequent and more costly maintenance. Charles Bauer stated that a particulate
be installed before the air stripper, and will forward a revised treatment system
ion request.
Before establishing a discharge limit for any chemicals or compounds not specifically
with the contamination at the site (i.e. iron, lead, manganese, etc.), this Office
Js having the applicant submit laboratory analyses of groundwater samples collected
-site monitoring wells. If the in -situ level of a chemical is below the proposed
)ermit limit, it should be unnecessary to include the chemical in the permit.
Prior to being reactivated, any spent carbon from the treatment system should be
isure that it is not classified as a hazardous waste. The testing must be conducted t
the spent carbon is managed properly.

Vort" Flow Sensors
Vortex flow sensors use a naturally
occurring phenomenon in which whirling
mosses of liquid, or vortices, are shed
downstream of a stationary object within
a fldWstreom, and at a frequency
directly proportional to the velocity of
the flow stream. Each vortex causes a
local pressure fluctuation that can be
detected. +GF+ SIGNET Vortex Flow
Sensors, 1/2 to 2', develop vortices
around a narrow bluff body and direct
them tci encapsulated piezoelectric
sensor, The electrical impulse signal from
the sensor is amplified and conditioned,
producing an extremely accurate and
reliable output that is directly propor-
tional to the flow rate.

• Six common installation configurations are shown
as guidelines to help you select the best location in
your piping system for a vortex flow sensor. Always
maximize distance between sensors and pump
sources.
• All mounting angles are acceptable in either
horizontal or vertical pipe runs, with upward flow
preferred in the case of vertical runs. Install the
sensor with the arrow pointing in the direction of the
flow. These flow sensors are for uni-directional
operation,
• Observe minimum Reynold's Number and back
pressure requirements,
Reynold's Number
• A Reynold's Number is a dimensionless number used
to determine the effects of viscosity, specific gravity,
and velocity on flow sensor performance, To
maintain system accuracy, a Reynold's Number
greater than 7,500 is required.

AquAir WWTP Upgrade
Authorization to Construct No. 086673AOI
Request for Additional Information
1. According to the DMR data submitted for this facility in 2004, the flaw at the AquAiR WWTP
ranged from a monthly average of0.00732 mgd to 0.0162 mgd (7,320 gpd to 16,200 gpd).
What is the expected flow from the two proposed recovery wells to be added? And what are
the total flaws treated by the WWTP expected to be?
2. Regarding the proposal to replace the existing air stripper with a more efficient one. -
(a) It is not dear from the submitted documents (see Appendix C) how many trays are to
be provided in the proposed air stripper. Please clarify.
(b) Please provide expected influent VOC concentrations, and document that the proposed
air stripper is capable of producing effluent results below the NPI ES permit limits.
(c) Will the increased VOC removal from the proposed air stripper affect any air quality
permit required by this WWTP?
Regarding the proposed addition of another 1,000 pound granular activated carbon (GAC) unit
(liquid phase):
(a) It is not clear what amount ount of VOC removal is'necessary from the GAC units in order
to achieve the NPDES permit limits, or if the GAC units are essentially acting as a
treatment safety factor. What are the removal efficiencies of the existing GAC" unit,
and the proposed one? Please clarify.
(b) Is the GAC material in the GAC units replaced on a periodic basis? What is the
frequency of replacement
According to the submitted DMR data for this facility, the effluent concentration of
tetrachloroethene during .tune 2004 was 34.4 p 11, with the effluent limit being 31.3 trg11.
Please attempt to identify why this exceedance of the permit limits occurred. Flow will the
proposed treatment scheme beep this type of exceedance from happening again?

Aquair Groundwater Rernediat on Project
Mecklenburg County
S&ME Inc. Project No. 1354-92-175B
Dear Mr. Eelnicic.
In response to, your request for additional information regarding the feasibility of land -based
disposal for the above referenced project, S&ME, Inc. (S& ) has prepared the following
information.
1. Current North Carolina Department of Environment and Natural Resources - Division of Water
Quality (DWQ) standards regarding minim requirements for land -based disposal systems,
2. Site information regarding soil properties and characteristics for the site, and
. Evaluation of feasibility for land based disposal.
NORTH CAROLINA REGULATIONS
Regulations ulations regarding the wastes not discharged to surface waters are covered in the North Carolina
Administrative Code 15A NCAC 2H .0200. These regulations require that a licensed sail scientist
evaluate the potential receiver situ to determine the presence of limiting soil conditions such as:
• law permeability clays
• seasonal water table features. and
• actual water table features.

Additional Information for NPDES Permit NC0086673 S ME Project No. 1354- 7-1" 5B'
NCDENR. -- N 'I ES October 6, 1999
Although not a part of these regulations, all non -discharge permits are written such that application
can not occur while the distance to the actual water table is less than inches: Typically a
minimum of 18 inches of suitable treatment zone that is free from restrictive horizons and seasonal
or actual water tables is required.
SITE INFORMATION
The site includes 154 acres that are mapped as Mecklenburgd Iredell soils (Figure 4.2-1). A
licensed S&ME soil scientist conducted an investigation of the site soils on the property: The
purpose of the investigationwas to determine the suitability of soils for land -based disposal.
Iredell Soil Series
The majority of the site contained soils that had been mapped as the Iredell soil series (map units
IrA and IrB). The Iredell soil series is typically moderately well drained and characterized by
sticky expansive clays. Listed in the soil survey are descriptions of the areas that these soils are
found d any'areas of other soils that were included in the map units. Inclusions in the areas
mapped as Iredell, are soils that are found on wet weather ponded areas. A description of these
soils was not given in the Mecklenburg County Soil Survey,
Investigations on the portions of the site snapped as Iredell indicated that areas of the wet weather
ponded soils were prevalent in map unit IrA and IrB. Typically these soils contained seasonal
water tables within 12 inches of the soil's surface. Small isolated areas of shallow soils such as
Wilkes and Enon were found adjacent to areas mapped as Mecklenburg. These soils contained
sarolite and /or seasonal water tables within 18 inches of the soil's surface.

t
Additional Information for NP ES Permit NCO086673 S ME Project No. 13 5 - 7-175B
NCDENR -- NPQES October 6' 1999
Mecklenbure Sail Series
Sails that were mapped as the Mecklenburg soil series are typically well drained d are better
suited to land -based disposal. S& `investigations were more concentrated on these areas clue to
the potential of favorable soil conditions.
Investigations into the Mecklenburg (MeB map it) portion of the site indicated this map unit was
not as extensive as mapped in the Mecklenburg County Soil Survey. A small area. (approximately
acres) of soils more typical of the Mecklenburg soil series was found on the northwest comer er o
the site. After buffer restrictions from ,property lines and roads are applied to this area; less than an
acre of useable for land -based disposal exist. The soils investigation of the MeB map unit found
soils similar to those found in the Iredell map units. Some small isolated areas of Wilkes and Enon
soil series were noted. These soils had similar properties to those found the Iredell map unit.
Also found were variants of the Mecklenburg soil series that had expansive clay acting, as a,
restrictive horizon within 14 inches of the soil's surface. The expansive clay will limit soil
permeability and may promote surface runoff conditions.
EVALUATION OF FEASIBILITY FOR LAND :BASED DISPOSAL
SME soil investigations on the site found the soils that are not consistent with. the Mecklenburg
County Soil Survey. Soils encountered on the site do not meet surface water duality and'
groundwater directives for the NCAC I5A 22H .0200 regulations for land -based disposal. In
general the site has areas with insufficient separation to seasonal water tables for groundwater'
protection and areas with restrictive clays which may promote soil runoff. Useable areas of the site
that were noted would be reduced to less than one acre in size due to the proximity of property lines
d roads.

AquAir Site May I O1999
The AquAir Site is located at 13300 Sam Neely Road in southwestern Charlotte near
Westinghouse Boulevard in a heavily developed commercial and light -industrial area. The Site
consists of a 2-acre former industrial facility (the "Facility") within a 154-acre undeveloped,
heavily wooded tract owned by SNL. The Site location is shown in Figure 2_2- 1,
The Facility has a perimeter fence and contains the shells of a former production building and a
former laboratory building. Figure 22-2 shows the Site plan. An abandoned water supply well
(ESW-1) is located immediately east of the former lab. A septic tans is located inside of the fence
along the eastern side of the former production building. The septic tank was replaced with a
connection to the Charlotte/Mecklenburg County Utilities Department ("CMUD") sewer system
in the 1970s.
An unnamed, southward -flowing tributary to Steele Creek (the "creek") is located on the
property approximately 900feet east of the Facility. A railroad track and CMUD sewer line are
located between the Facility and the creek.
to 1972; (2) solvent recovery, reclantation, and blending from 1974 to 1984; (3) bulk chemical
repackaging from 1974 to 1976; and (4) laboratory services and chrorni-arn compound
manufacturing front 1977 to 1988. No manufacturing activities have been conducted at the Site
since 1988.
Because of suspected soil and/or groundwater contamination at the Site, the North Carolina
Superfund Section performed Phase I and Phase 11 Screening Site Inspections in 1990.
Subsequent to these inspections, Delta Environmental Consultants ("Delta") conducted a more
comprehensive investigation in 1993 for the owners of the Site. The Delta investigation
'confirmed several areas of soil and sediment contamination, and groundwater contamination,
principally chlorinated volatile organic compounds ("VOCs"), in the Shallow Aquifer.

AquAir Site May R 1999
As follow-up to the Delta investigation, Geraghty & Miller, Inc. ("G&INI") performed
supplemental investigation activities in 1995-96, The G&M investigation further refined the
definition of the extent of soil contamination and Shallow Aquifer groundwater contamination,
S&ME performed a Supplemental Site Investigation ("SSI") in 1997-98 to collect sufficient data
to evaluate the extent and magnitude of contamination at the Site in order to identify remedial
and iniplementability of selected remedial options. Estimated costs have been developed for
remedial/investigative activities that will, probably be required by state regulatory agencies.
The following conclusions have been derived from data from the S&ME's SSI, and the Delta and
GI investigations.
I The hydrogeologic sequence at the Site consists of two units, the Shallow Aquifer and the
Bedrock Aquifer. The Shallow Aquifer is formed by the unconsolidated materials. which
range in thickness from 5 to 50 feet, The Shallow Aquifer is under water -table aquifer
conditions. Groundwater flow is generally to the east. Discharge from the Shallow
Aquifer is believed to be to the creek located about 900 feet east of the Facility.
The Bedrock Aquifer is present below the Shallow Aquifer and appears to be in direct
hydraulic connection with the Shallow Aquifer, Groundwater in the Bedrock Aquifer is
present in fractures. Groundwater -bearing fractures were found to depths of 120 to 130
feet below land surface ("BLS"). Groundwater flow is generally to the cast. Discharge
from the Bedrock Aquifer is believed to be to Steele Creek, which is located
approximately 0.5 mile east of the Site.
2. Surface water and sediments in the intermittent creek do not appear to have been
impacted by Site contaminants.
1 Shallow soils at the Site have been impacted by metals, including chromium (both
hexavalent and trivalent), lead, and van adium. and chlorinated VOCs, although some
impact from semi -volatile organic compounds ("SVOCs") is present. Metals, including
principally chromium with subsidiary amounts of lead, and vanadiu m. have impacted
sediments at the Site in two small drainage swales east of the Facility.
Most of the contaminated soil is located beneath or adjacent to the former production
building (chromium and VOCs/SVOCs), the labonatory building. and the septic tank
(chromium and VOCs), Some of the soil beneath the southeastern concrete slab of the

Aquifer VOC groundwater plurne is shown in Figure 2.2-1.
5Groundwater in the Bedrock Aquifer is contaminated principally by chlorinat,
although some non -chlorinated VOCs are also present. Maximum VOC conc(
are approximately 125 mg/L.
VOC contamination in the Bedrock Aquifer extends to a depth of approximate
130 feet BLS. The Bedrock Aquifer groundwater plume extends laterally gene]

groundwater plume is shown in Figure 2.2-1.
2.3 Screening of Technologies and Remedial Options
Shallow and Bedrock Aquifers are discussed in this section.
2.3.1 Shallow Aquifer
Remedial technologies for the Shallow Aquifer include in situ bioremediation, air sparging,
pump and treat, and in situ treatment walls.
1) In Situ Bioremediation
In situ bioremediation stimulates existing subsurface microorganisms. also known as
methanotrophs, to breakdown chlorinated VOCs into less hazardous substances. The
VOCs degrade to chloride, carbon dioxide, water. and ethane. The technology has been

NPD S Permit Application and EAA S ME Project 135-97-1751
AquAir Site May 10, 1999
shown effective for treating chlorinated VOCs. Nutrients and food sources for the
methanotrophs are injected into the groundwater system. :hood sources include alcohols,
sugars, fatty acids, and natural gasses. Several studies have been performed in which
methane is used as the food source for chlorinated-VOC degradation.
Multiple injection wells are required to inject the nutrients and food source into the aquifer.
The injection operation causes groundwater mounding and an alteration of the
groundwater flow regime. Extraction wells are subsequently required to control the plume.
Design, capital, and consti ction costs are higher than for a sparge system. Operations
and maintenance cosh are much higher than a sparging system especially the cast of the
food source. Operation of the system is complex because of the need to bakince water
flow mud nutrient/food source levels in the aquifer. Although the technology is a potential
option for the Site, in ,situ bioremediation will not be retained for further evaluation
because of higher casts and operational complexity ;with no added effectiveness when
compared to air sparging.
2) Air Sprgin
Air sparging injects air into the lower portion of an aquifer to remove VOCs front the
groundwater er by the rising streams of bubbles. Air sparking works vouch like an air
stripper, by agitating water tined transferring the contaminants from the liquid please to the
vapor phase. Air sparging is often perfo ned in conjunction with a method to recover the
vapor to provide control of the contaminants being removed by the system.
Art air-sparging pilot test was performed and the results indicated that the technology was
very effective producing a radius of influence on the order of 30 feet around the test well.
Air sparging will be further evaluated as to potential remedial alternative for the Site.
:) Pump and Treat
A pump -and -treat system extracts groundwater through the use of wells, treats the water
using standard: tecluiologies, and discharges the treated water to a storm sewer, local
Publicly Owned Treatment Works ("POTW"), infiltration/injection system, or a surface -
water body. Treatment techriologies include air stripping, activated carbon, and UV
oxidation. The pump -and -treat technology has existed for years; however, the systems
tend to require years of operation. This technology; is relatively less aggressive than air
sparging and airsitu biodegradation.
Management of the treated water is often a critical` issue. Currently, the local POTW,
operated by the Charlotte -Mecklenburg Utility Department ("C UD") does not allow
effluent from.: groundwater remediation to enter the POTW. Because of this restriction,
effluent from the system will have to be discharged to the nearby unnamed creels, which
will require a National Pollutant Discharge Elimination System. (""NPDES") permit. Pump
and treat will

of the lengthy operational period and no added effectiveness when compared to 'air
sparging,
) In Situ Treatment "Walls
Insitu treatment walls are constructed of iron filings and are installed do ngradient of the
plume perpendicular to the direction of groundwater flow. As the contaminated
groundwater passes through the treatment wall.the chlorinated VOCs are dehalogenated
by the iron filings. The resulting constituents are methane, ethane, and chlorinated salts.
Treatnnerit walls are a passive technology with little operation and maintenance costs.
One difficulty with the technology is to ensure that the contamimted groundwater passes
through the wall and not around or under the wall, For application at the Site:. the wall
would have to be approximately 400 feet long and be keyed into the bedrock
(approximately ' 25 to 40 feet deep). The top of bedrock' at the Site is irregular and
fractured; therefore, the wall play not be properly keyed into bedrock. If this occurred,
contaminated groundwater could bypass the wall without treatment. Due to the size of the
wall and the difficulty of keying the wall' into the top of bedrock., treatment walls will not
be further evaluated.
2.3.2 Bedrock Aquifer
Remedial technologies for the Bedrock Aquifer include in situ bioremediation, air sparging, and
pump and treat.
1) In Situ Biore ediation
As described above, in sins biore mediation is as potential option for the Bedrock; Aquifer at
the Site. However, it plementation and control of the technology in a fractured bedrock
aquifer is not considered practical and the technology will not be retained for further
evaluation
) Air Spargin
As described above, air sparging is a potential option for the Bedrock Aquifer at the Site.
However, implementation and control of the technology in a fractured bedrock aquifer is
not considered practical and the technology will not be retained for further evaluation.
3) Pump and Treat
As described above, pump -and -treat technology is considered to be a potential option for
the Bedrock Aquifer at the Site and will be evaluates) further as a remedial option. Based
on the results of the pump test, extraction of VOC-contaminated groundwater from the
Bedrock Aquifer will also hydraulically control the Shallow Aquifer groundwater plume.

A residential future -use scenario was not used because the Site is expected to be developed for
industrial/commerciat uses in the future. Use of groundwater for potable water supply is also not
selected as an applicable scenario because the area is supplied by the municipal water system.

3.0 PROPOSED REMEDIATION SYSTEM ENGINEERING DESIGN
3.1 General Information
VOC-contaminated groundwater will be recovered from the Bedrock Aquifer by a series of
pumping wells.
9 ne.
The recovered groundwater will be treated with a shallow -tray air stripper and liquid phase carbon
to remove the VOCs. The remediation system is discussed in further detail in Section '). l . I , The
facility will obtain an air permit to construct/operate the system from the Mecklenburg County
Department t ent of Environmental Protection (MC EP) for air emissions. Long-term disposal of
treated grolindwater is proposed to the c under an NPDES permit.
A temporary ,permit to discharge to the existing sanitary sewer system will be requested from
CM D in the interim while the NPDES surface water discharge perinit application is wider review
by the NCDENR. Currently, CMUD does not allow tong -term disposal of treated groundwater to
the sewer system. Aqueous -phase carbon treatment of the treated groundwater from the stripper
will be performed during startup to ensure that NPDES permit levels are met.
As part of the pilot testing program, an aquifer test was performed at Bedrock Borehole A`I" -d .
The technology was very effective, with a feet for ATB-02.
Drawdown was observed in all bedrock wells and in potentially all Shallow Aquifer monitoring
wells at the Site.
The Site subsurface conditions are conducive to hump and treat.
Site.
Three extraction wells will be used in the pump and treat system. Existing wells TB-01 and
ATB-02 will be used. A third well location to be determined will also be used as all extraction
well.

2) a liquid phase carbon adsorber.
Carbonair Model PC 7P liquid phase carbon adsorber (or approved equivalent) consisting
of the following:
• 3' diameter x .3' FRP vessel;
• 00 lbs of reactivated liquid phase carbon;
Maximum design pressure 150 psi; and
• Inlet and Cutlet pressure gauges and sample parts;
The air stripper will be designed to meetanticipated NPDES discharge requirement. The liquid
phase carbon adsorber is included in the treatment system as in additional or back-up treatment unit
to the air stripper. Liquid phase carbon will be replaced as necessary and spent carbon will be
reactivated off -site. Estimated air stripper removal efficiencies are provided in Appendix 1.
Long-term disposal of the treated water will be accomplished through discharge to the proposed
receiving stream near the Out -fall 001 shown on Figure 2.2-1 Appropriate encroachments will be
applied for and granted by the Norfolk Southern railroad company to bring water, electric, and
phone lines beneath the railroad right-of-way.
The groundwater treatment system will be placed in a remediation building. The proposed
footprint of the building will be a acid the height of the building will be
approximately 15'. The remediation building will be constructed with a concrete slab floor that
will drain to a sump located in the center of the building. The sump` will contain a float switch and
a surrip pump. ; The stimp pump will pump the collected water to the surge tank. The various
components of the system will have pressure gauges and low, high, and high -high switches to
deactivate the system in the event of a failure of one or more ofthe components. In addition to on -
site remediation system controls, the system control panel will be equipped with remote control and
monitoring telemetry system that will allow for remote monitoring of the system performance.'
The proposed pump and treat system will be constructed and installed at one time. The start -:tap of
extraction wells feeding the pump and treat system will be phased. Initially, the system will run
one well (AiT001) at approximately 15 to 20 gallons/minute. Two additional wells, A 3T002 and
a well yet to be determined; will Pump into the system after start-up, Well ABT002 will start

gallons/minitte. The well to be determined will start pumping approximately 6 months after start-
up at a rate of 15 to 20 gallons/minute.
-3.1.2 Operation and Maintenance of the System
An inspection program for the pump and treatment system is discussed below and will help meet
several important objectives:
Prevention of accidental releases of recovered groundwater to the
environtnent
• Reduction of risks from exposure resulting from releases
Maintenance of a safe work place
` The identification of potential problems and the implementation of
corrective actions
Increase in efficiency and productivity of'the pu np and treat system
To accomplish these objectives, system checks and O&M will be performed weekly,; with daily
checks on the system operation (i.e:, ON/OFF) daring the system start-up period (first 3 months of
operation). The data collected during; the weekly checks will be recorded in a bound project
logbook. The system checks will include reading the various gauges and flow meters on the
system. Frequent visual inspections will be made of all equipment associated with the groundwater
treatment system. A partial list of inspection items is as follows:
• Valves:`: packins, seals, ease of turning and leak tightness should be
checked. Valves should be exercised at least twice yearly.
Pressure Relief Valves: check to see they are not plugged.
Electrical Grounding Wires: should be electrically checked to see
that they are properly connected.'
Level Gaines: should be checked for corrosion and to make sure
that they are not "hunt up" or otherwise inoperable.

3.3 Reduction of Contaminant Toxicity, Mobility, or Volume
Through operation of the system contaminant toxicity, mobility and volume will be reduced.
The pump and treat system is directed at the highest concentrations in the Bedrock Aquifer, but
will also hydraulically control the Shallow and Bedrock Aquifer groundwater plumes to
eliminate additional migration. Pump and treat will remove and control the Bedrock Aquifer
contaminants.
Treated groundwater from the air stripper will initially be treated using aqueous carbon
adsorption. Spent carbon will be transported off -site and thermally regenerated, destroying the
VOCs. The spent carbon, and soil from well installation. will be the only residual materials

generated during implementation. Direct discharge to the atmosphere of vapors from the stripper
will occur because VOC emission levels, are expected to be below Mecklenburg County air
standards.
3.4 Short -Term Effectiveness
The pump and treat system is effective in the short-term because the contaminant plumes in both
aquifers will be controlled to prevent any further migration. This system consists of well
installation and trenching, which are standard construction activities. The estimated time to
install the system is three to six weeks.
The Site is relatively remote and located inan industrial portion of Charlotte. During intrusive
activities, engineering controls will be implemented to protect the rernediation workers. The
time to achieve remedial objectives is difficult to determine. For estimating purposes, the
assumed operational time for the system will be 10 years.

3.5 Implementability
This remedial system uses standard activities to achieve the remedial goals. The pump and treat
system is flexible and allows expansion or reduction of the number of wells and pumping rates,
as necessary. Performing Bedrock Aquifer monitoring will provide the ability to monitor the
effectiveness of the system.
Well permits from NCDENR will be required. The MCDEP will require a permit for air

4.0 EVALUATION OF WASTEWATER DISPOSAL ALTERNATIVES
S ME has reviewed several alternatives to surface water discharge for the long-terin disposal of
treated groundwater from the proposed pump and treat system as part of this permit application
package. The following g alternatives were evaluated: connection to a sanitary sewer system. land
based disposal, wastewater reuse, and surface water discharge. Based can the evaluation, surface
water discharge was the only environmentally entally sound, technically feasible. reasonably cast -
effective alternative for long-term disposal of the treated groundwater. A Brief summary of
conditions that limit or prohibit the use of the alternatives listed above follows.
4.1 Connection to a Sanitary Sewer Collection System
The subject site is located in Mecklenburg County, North Carolina. Publicly owned sanitary
sewer services at the Site are provided by CMUD. CM 1D has placed a moratorium on the
acceptance of long-term discharges from groundwater- treatment units, such as the pump and treat
system proposed for the Site. CMUD will issue short-term discharge permit to discharge treated
groundwater. Therefore, connection to a publicly awned treatment works (POTW) is not a
viable long-term treated groundwater disposal option for the proposed remediation system.
There are no privately owned treatment works located near the Site. Therefore, connection to a
privately owned treatment ent works is not viable Iong-terrn treated groundwater disposal option for
the proposed remediation system.
4.2 Land Basest Disposal
Soil type and the depth of the soil profile are important components in subsurface disposal.
Conditions at the Site are not conducive to subsurface disposal. Based on the Soil Survey of
Mecklenburg County, North Carolina (united States Department of Agriculture, 1979),
.underlying soils at the site consist of lredell and Mecklenburg complex soils. A copy of the soil
survey map, with the site annotated is attached (Figure .2-1). These soils generally exhibit low
perrneabilities, which are not amenable to subsurface rface discharge. Well : log information,
(,Appendix 111) supports the soil characterisation found in the Mecklenburg County' soil survey
map for the Site. In addition to clay and clayey silt soils found in the upper 3.5 to 5 feet of the

Site, well monitoring data (Appendix IV) indicates that groundwater elevations in portions of"the
Site are within 2 to 5 feet of the ground surface. fused the shallow depth to groundwater
observed at several locations, an adequate depth of unsaturated soil for subsurface discharge is
not present at the Site. Therefore. lased on the limiting conditions of low permeability shallow
soils and shallow groundwater subsurface discharge alternatives are considered unsuitable
wastewater discharge alternative for the Site.
Surface non -discharge (spray/drip(spray/drip irrigation) wastewater disposal alternatives were also
evaluated. As discussed above, based on the Mecklenburg, County Soils map and field
observations, the majority of the Site consists of Ired ll soils that have a very low permeability
and shallow depths to groundwater. Because of the shallow depth to groundwater (2 to 5 feet
below existing ground surface) and the low permeability soil characteristics, spray/drip irrigation
is considered an unsuitable wastewater discharge alternative for the Site.
4.3 Wastewater Meuse
Currently there are no industrial or rather processes operating at the Site that could reuse the water.
Reuse of the treated groundwater is considered an unsuitable wastewater discharge alternative for
the Site.
4.4 Surface Water Discharge
Surface water discharge of the treated groundwater from the pump and treat system was evaluated
and is proposed as the only environmentally sound, technically feasible, reasonably cost-effective
alternative for long-term disposal of the treated groundwater. An unnamed tributary to Steele
Creek moon through the center of: the Site and provides a discharge outfall for the treated
groundwater on the property. Based on flow calculations following the United States Geological
Survey (USGS) procedure, the flow for the receiving stream at the proposed
,outfall location are :,ubic feet per second, respectively. Calculation for the 7Qld
and 30Q2 flow are attached in Appendix V. The 7Q1O stream flow is the 7-day consecutive low -
flow that on average will be exceed 9 out of 10 years. The 3OQ2 strearn flow is the 30-day '
consecutive low -flow that on average will be exceeded I out of 2 years.

HuB--Helena-Urban land complex, 2 to 8 percent
slopes. This map unit consists of areas of Helena soils
and areas of Urban land primarily in the suburban areas
of Charlotte. These areas are too small and too intricate-
ly mixed to be mapped separately. The undisturbed
Helena soil makes up 50 to 70 percent of each area,
and Urban land makes up 15 to 35 percent. The rest of
this unit consists of areas where most of the natural soil
has been altered or covered as the result of grading and
digging.
The undisturbed Helena soil is well drained. Typically,
the surface layer is light olive brown sandy loam about 8
inches thick. The subsoil is 32 inches thick. The upper
part is brownish yellow sandy clay loam, the middle part
is brownish yellow and yellowish brown clay, and the
wer part is mottled yellowish brown, light gray, and
ddish brown clay loam. The underlying material to a
depth of 50 inches is light gray sandy clay. Below that, it
is light gray sandy clay loam.
The organic matter content is low in the surface layer
of this Helena soil. Permeability is slow, the available
water capacity is low, the shrink -swell potential is high,
and surface runoff is medium. The subsoil is very strong-
ly acid or strongly acid. Depth to rippable bedrock is 40
to 60 inches. The seasonal perched water table is 1 to
2.5 feet below the surface.
The Urban land part of this unit is covered mostly with
closely spaced houses, paved streets, parking Tots, drive-
ways, small shopping centers, industrial buildings,
schools, churches, and apartment complexes.
In some altered, or disturbed, areas the Helena soil is
covered with more than 20 inches of fill material. In
others, more than two-thirds of the natural soil has been
removed by cutting and grading.
Included with this complex in mapping are small areas
of Appling, Enon, Monacan, and Vance soils.
Surface runoff from rooftops and paved surfaces in-
creases the hazard of flooding in low-lying areas down-
stream. The clayey subsoil is a limitation in landscaping.
The slow permeability, the wetness, and the high shrink -
swell potential are limitations for most urban uses.

Most of the acreage is used for crops, hay, or pasture.
Some areas are forested.
This soil has moderately high potential for most crops.
Small wet areas and slow permeability are the main
limitations in the use and management of this soil. Tilth
can be improved by returning crop residue to the soil
and by not tilling the soil when wet. Erosion is a slight
hazard. This soil has high potential for pasture forages
(fig. 4).
The potential is moderate for broadleaf and needleleaf
trees. The dominant trees are loblolly pine, shortleaf
pine, post oak, and white oak. The dominant understory
species are dogwood, redbud, holly, sourwood, and
black cherry. The clayey subsoil is the main limitation in
woodland use and management.
The potential is low for most urban uses because of
the very high shrink -swell potential, the wetness, and the
slow permeability. The slow permeability significantly
limits the absorption of effluent in septic tank absorption

Most of the acreage is used as woodland. Some areas
are used for hay, pasture, or crops.
This soil has high potential for corn, soybeans, small

crop residue to the soil, and the use of cover crops,
including grasses and legumes, reduce runoff and help
to control erosion.
This soil has moderately high potential for broadleaf

The potential is low for most urban uses because of
wetness, the slow permeability, and low strength. The
slow permeability significantly limits the absorption of

rective measures to overcome low strength are increas-
ing the size of the footings and, where appropriate, plac-
ing structures on slabs. Surface drainage, tile drainage,

's medium acid to neutral. Depth to bedrock ranges from
18 to 60 inches. The water table is below 6 feet.
Most of the acreage is used as cropland and pasture.
The rest is forested.

SOIL SURVEY
This soil has moderately high potential for corn, soy-
beans, pasture, hay, small grain, and most horticultural
crops. Erosion is a hazard if cultivated crops are grown.
This loss of the original surface layer reduces tilth. Mini-
mum tillage, the return of crop residue to the soil, and
the use of cover crops, including grasses and legumes,
reduce runoff and help to control erosion.
The potential is moderate for broadleaf and needleleaf
trees. The dominant trees are loblolly pine. Virginia pine,
shortleaf pine, eastern redcedar, white oak and red oak,
hickory, yellow -poplar, sweetgum, and sycamore. The
dominant understory species are dogwood, redbud, holly,
sourwood, and black cherry. There are no significant
limitations in woodland use or management.
This soil has low potential for most urban uses be-
cause of the slow permeability, the moderate shrink -
swell potential, the low strength, and the depth to bed-
rock. The slow permeability significantly limits the ab-
sorption of effluent in septic tank absorption fields. This
limitation generally can be overcome by modifying the
field or by increasing the size of the absorption area, or
both. Corrective measures commonly used for low
strength include increasing the size of the footings and
where appropriate placing structures on slabs. Strength-
ening the footings and foundations and removing excess
moisture are corrective measures for shrink swell. The
potential is only moderate for camp areas and play-
grounds because of the slow permeability. It is high for
most other kinds of recreation.
The capability subclass is Ile. The woodland group is
4o.
MeD—Mecklenburg fine sandy loam, 8 to 15 per-
cent slopes. This well drained soil is on side slopes on
the uplands. Mapped areas are narrow, oblong bands
that range from 5 to more than 100 acres.
Typically, the surface layer is dark reddish brown fine
sandy loam about 7 inches thick. The subsoil is yellowish
red clay 27 inches thick. The underlying material to a
depth of 45 inches is mottled strong brown and yellowish
red clay loam. Below this to a depth of 65 inches it is
very dark grayish brown and light olive brown loam.
Included with this soil in mapping are a few small
eroded areas where the surface layer is clay loam, a few
areas where the subsoil is dark red, and a few areas
where the subsoil is thicker than 32 inches. Also includ-
ed are a few intermingled areas of Cecil, Enon, and
Wilkes soils. The included areas, each less than 5 acres,
make up 10 to 20 percent of this map unit.
The organic matter content is low in the surface layer
of this Mecklenburg soil. Permeability is slow, the availa-
ble water capacity is medium, the shrink -swell potential
is moderate, ;and surface runoff is rapid. Reaction in the
subsoil ranges from medium acid to neutral. Depth to
bedrock ranges from 48 to 60 inches. The water table is
below 6 feet.
