MOORESVCt. E,mr: REGIONAL OFFICE
On behalf of Quality oil Company, LLC, Terraquest Environmental Consultants, P.C. hereby
requests rescission of the NPDES permit for the Springs Road Gas House in Hickory, NC. The
Certificate of Coverage (NCG510384) under the general groundwater remediation permit
(NCG510000) previously allowed the discharge of groundwater following its treatment by an
onsite remediation system. That system performed well and the former petroleum release
incident is now in a period of monitored natural attenuation. Since the pump and treat system
is inactive and discharge is no longer occurring, the permit is no longer needed.
Please call me at [phone] with any questions you may have. Thank you.

Ryan,
It was a pleasure chatting with you today regarding the groundwater remediation system for the Quality Oil
Company. As I noted you can ask for rescission of the Certificate of Coverage (NCG510384) under the general
groundwater remediation permit (NCG510000) by writing a letter to the permitting group. Your letter should ask for
rescission and give the details why the permit coverage is no longer needed (system shutdown, no power, in natural
attenuation period, etc.).
Here is the contact information for your letter:
Division of Water Resources
Water Quality Permitting Section - NPDES
1617 Mail Service Center .
Raleigh, NC 27699-1617
I'll try to get by there before your letter gets to Raleigh so staff in the central office can issue the rescission letter quickly.
If you have any questions please do not hesitate to give me a call.

Dear Perimttee:
The facility listed above is covered under NPDES permit NCG510000 for discharge of reinediated,
groundwater. NCG510000 expires on September 30, 2006. Federal (40 C.YR 122,4I) and North Carolina (15A
NCAC 2H O'105(e)) regulations require that permit renewal applications must be filed at least 180 days prior
to expiration of the current permit. If you have already mailed your renewal request, you may
disregard this notice.
To satisfy this requirem..ent, the Division must receive your renewal request postmarked no later than
April 3,,2006., Failure to request renewal by this date may result in a civil assessment of at least $500.00.
Larger penalties may be assessed depending upon the delinquency of the request.
If any discharge from the remediation system will occur after September 30, 2006, your Coe must be
renewed. Discharge of wastewater without a valid permit would violate North Carolina General Statute 143-
215.1; unpernitted. discharges of wastewater may be assessed civil penalties of up to $25,000 per day.
If you have halted remediation activity due to lack of trust fund money, but your site ranking from the
Aquifer Protection Section requires future remediation & discharge, your CoC must be renewed.
If all discharge has ceased at your facility and you wish to rescind. this CoC [or if you have other
questions], contact me at the telephone number or e-mail address listed below.

Dear Mr, Stroud:
The Division acknowledges receipt of your Notice of Intent for coverage under General
Permit NCG510000, sealed plans and supporting materials, in triplicate, and two checks
(# 3592 for $400 and #3593 for $150) received on March 21, 1997.
Please send additional information on the following items:
• Discharge alternatives - please indicate where the nearest POTW is located, how much
development is in the area, and more information on the non -discharge infiltration option. 1
am sending a guidance document for non -discharge options to your consultant.
• The removal efficiency for the treatment system was modeled using 4 gprn and 80 cfm.
through the STAT 15 air stripper, although the application requests up to 4000 gpd (2.8
gpm.) and the maximum air flow to the stripper is stated as 60 cfm in the manufacturers
specifications; please specify which flow rates the system will be run at.
• The calculations for carbon usage were determined using 98.8% efficiency (8,500 ppb
effluent concentration), but the STAT 15 has an efficiency of 93.5%, after 4 trays (18,000
ppb effluent conc.) and 4 gpm. Please remodel at 3 gpm, and show how the carbon usage
rate of 2.25 lbs per 1000 gallons was determined.
The monthly carbon usage rate is based on 1.5 gpm throughput, please remodel this at
3.0 gprn. This would indicate a carbon usage rate of 600 lbs per month, One month of
carbon on -site is a preferred design parameter for ground water remediation systems.
Also, are the carbon tanks in series or parallel?

1.0 INTRODUCTION
This Corrective Action Plan (CAP) has been prepared by Turner Environmental Consultants,
P.C. (TEC) on behalf of Quality Oil Company, Ltd. (Quality) of Winston-Salem, North Carolina.
The CAP proposes a strategy for the reduction of gasoline constituents in soil and
groundwater at the Springs Road Gas House located in Hickory, North Carolina (Figure 1).
An underground storage tank (UST) system, which was operated at the facility by Quality,
released an unknown quantity of unleaded gasoline into the soil and groundwater.
Groundwaters at the site are class GA under the North Carolina Division of Water Quality's
(NCDWQ's) classification system and are subject to standards mandated under Title 15A
NCAC 2L .0202(g). These will be referred to as "2L standards."
On April 26, 1994, TEC supervised the permanent closure and removal of three (3) gasoline
USTs. The USTs were replaced with new USTs as part of a planned facility upgrade and
remodeling. A site plan is shown in Figure 2. Note that the former UST system is shown in
this figure. During the UST closure, petroleum impacted soil was discovered. The NCDWQ
was notified of the release and corrective action was initiated by Quality. These actions
included the closure of the former USTs and the excavation and disposal of approximately 39
tons of contaminated soil.
Subsequent site assessment activities documented the presence of petroleum impacted
groundwater and free product or light non -aqueous phase liquid (LNAPL). The LNAPL area
is believed to be centered around monitoring well MW3. Up to 2.85 feet of product has been
detected in monitoring well MW3 to date. Surrounding the LNAPL area, petroleum impacted
groundwater with concentrations exceeding the 2L standards has also been identified.
Detectecn ounds include benzene, toluene, ethylbenzene, xylenes (BTEX , and methyl
teat butyl etlae (r�€)- Section 2.0 provides more details on the results of the site
assessment.
1

The property is currently owned by Quality and operated as a retail petroleum dispensing
station. None of the components of the former UST system are currently in place.
Previous permits issued to Quality for this facility consist of monitoring well installation
permits. Permit numbers are shown on Well Construction Records included in the previously
submitted CSA.
The NCDWQ - Mooresville Regional Office (MRO) issued a Notice of Regulatory
Requirements (NORR) to Quality on June 27, 1994. Key assessment activities, corrective
actions, correspondence, and report submittals to date include the following items, which are
listed in chronological order:
• April 26, 1994 - Quality closed the UST system at the site. The UST system
consisted of one 12,000 gallon, one 8,000 gallon, and one 6,000 gallon gasoline
UST. Approximately 39 tons of petroleum contaminated soil was excavated and
disposed of offsite.
► May 24, 1994 - TEC submited the UST Closure, Site Check, and Initial Abatement
Report.
► June 27, 1994 - The NCDWQ issued Quality a NORR. The NORR directed Quality
to comply with the release response and corrective action requirements of Title 15A
NCAC 2N.
► July 5, 1994 - TEC submited the Initial Site Characterization Report. The report
summarized the site assessment activities in order to comply with regulations under
Title 15A NCAC 2N .0704. Analytical results from soil samples collected from test
pits and soil borings revealed that petroleum impacted soil was in contact with
groundwater.
2

• August 10, 1994 - TEC supervised the installation of four Type 11 groundwater
monitoring wells (MW1 - MW4). These wells were installed to delineate
groundwater impact for the development of a Comprehensive Site Assessment
(CSA). LNAPL was detected in monitoring well MW3 during installation. Product
recovery efforts were initiated on August 24, 1996.
► November 1, 1994 - TEC submited a letter to the NCDWQ requesting additional
time to complete the CSA.
• November 10, 1994 - TEC supervised the installation of two Type 11 wells (MW5
and MW7) and one Type III well (MW6).
• December 2, 1994 - The NCDWQ issued Quality a Notice of Violation (NOV) in
response to the November 1, 1994 letter. The NOV was directed at the detection
of LNAPL and specified that free product recovery efforts should continue and
Quality should submit quarterly free product recovery reports.
► December 8, 1994 - TEC supervised the installation of one Type 11 groundwater
monitoring well (MW8).
• January 1995 - TEC submitted the first Free Product Recovery Report for the
facility. The report detailed recovery efforts since the installation of a passive
skimming system in monitoring well MW3 on August 24, 1994. As of January 18,
1994, approximately 32.5 gallons of LNAPL had been recovered.
► April 1995 - TEC submitted the Comprehensive Site Assessment Report to the
NCDWQ.
3

• May 1995 - TEC submitted the second Free Product Recovery Report for the
facility. As of May 16, 1995, approximately 48 gallons of LNAPL had been
recovered from monitoring well MW3.
► September 1995 - TEC submitted the third Free Product Recovery Report for the
facility. As of September 8, 1995, approximately 60.25 gallons of free product had
been recovered from monitoring well MW3.
• January 11, 1996 - The NCDWQ issued Quality a NOV siting an incomplete CSA.
Deficiencies in the CSA were primarily related to a surrounding potable well survey
which did not show potable wells within a 1,500' radius of the site. The NCDWQ
also requested the installation of a monitoring well in the vicinity of the septic field
to determine if the field could be acting as a preferential pathway for the migration
of contaminants.
► January 31, 1996 - TEC supervised the installation of two Type II groundwater
monitoring wells (MW9 - MW10). Monitoring well MW9 was installed at the request
of the NCDWQ, and MW10 was installed to provide better plume definition in the
upgradient direction.
► February 1996 - TEC submitted the fourth Free Product Recovery Report for the
facility. As of December 29, 1995, approximately 76.55 gallons of free product had
been recovered from monitoring well MW3.
• March 6, 1996 - TEC personnel conducted a more comprehensive receptor survey.
The primary goal of the receptor survey was to locate any potable wells, surface
water bodies, or other potentially sensitive receptors within 1,500 feet downgradient
of the contamination. Eighteen (18) potable wells were identified within the
immediate vicinity of the site.
4

• April 3-4, 1996 - TEC performed a 24-hour groundwater pumping test at the site.
The purpose of the test was to determine aquifer parameters for the design of a
groundwater treatment system.
• April 1996 - TEC submitted a CSA Addendum. The CSA Addendum detailed the
installation and sampling of two additional groundwater monitoring wells and results
of the receptor survey.
• May 1996 - TEC submitted the fifth Free Product Recovery Report for the facility.
As of April 24, 1996, approximately 83.55 gallons of free product had been
recovered from monitoring well MW3. This report also presented revised casing
elevation data from the groundwater monitoring wells. The wells were resurveyed
because an error in the previous survey was suspected.
• July 18, 1996 - The NCDWQ issued a site priority ranking to Quality. The site
priority ranking was brought about to address the continued solvency of the Leaking
Petroleum Underground Storage Tank Cleanup Funds. The site was ranked "B"
indicating high priority status.
► July 1996 - TEC submitted the sixth Free Product Recovery Report for the facility.
As of July 31, 1996, approximately 90.25 gallons of free product had been
recovered from monitoring well MW3.
• August 7, 1996 - TEC personnel conducted a soil vapor extraction (SVE) test at the
site. The purpose of the test was to determine the suitability of SVE.
► August 8, 1996 - The NCDWQ issued Quality a NORR indicating that the CSA
Addendum was complete and that a Corrective Action Plan (CAP) should be
prepared.
5

► August 8, 1996 - TEC personnel sampled the groundwater monitoring wells at the
site. This constituted the first sampling event in which all of the monitoring wells
(except MW3) were sampled on the same date. Monitoring well MW3 was not
sampled due to the presence of free product.
► September 1996 - TEC submitted the first Groundwater Monitoring Report for the
facility. The report details the analytical results of the sampling of monitoring wells
MW1 - MW10 on August 8, 1996. Monitoring well MW3 was not sampled due to
the presence of free product. The analytical results revealed that the extent of the
groundwater plume corresponds to historical data in the CSA.
In determining a remediation strategy, TEC has given first consideration to the options allowed
under paragraphs (k) and (1) of 15A NCAC 2L .0106. These are remediation (of groundwater)
to concentrations other than the 2L standards and natural biodegradation and attenuation,
respectively. Due to the presence of a substantial free product layer, natural attenuation is
not a suitable method for the site. However, remediation to risk -based groundwater standards
is reasonable and will be proposed herein.

2.0 SUMMARY OF SITE ASSESSMENT RESULTS
This section will summarize the key elements of the site assessment. The reader is referred
to previous reports, including the CSA and the UST Closure Report, for additional assessment
information.
2.1 Geology and Aquifer Characteristics
2.1.1 Topography and Stratigraphy
Springs Road Gas House is located in a mixed residential/commercial area of Hickory, NC at
the intersection of Springs Road and Section House Road. Surrounding properties and
property owner information are depicted in Figure 3. Land use in the site vicinity is primarily
residential with limited commercial development. Topography in the vicinity of the site may
be described as hummocky. The elevation of the site is approximately 1,130 feet M.S.L. The
topography in the immediate site vicinity slopes toward the west-southwest in the direction of
a tributary of Snow Creek. The topographic relief between the site location and Snow Creek
is approximately 120 feet. The land cover of the site consists of an asphalt lot with some
concrete areas and a surrounding grass landscaped yard.
The site lies within the Inner Piedmont lithotectonic province, a subdivision of the Appalachian
Piedmont Province of North Carolina (Brown, et al, 1985). The inner Piedmont Belt consists
primarily of metamorphosed sedimentary and volcanic rocks of late Proterozoic to early
Cambrian age, intruded by granodioritic to granitic plutonic bodies of early, middle, and late
Paleozoic age. Scattered Triassic -Jurassic age diabase dikes occur throughout the Inner
Piedmont. The lithology immediately underlying the site is mapped as sillimanite-mica schist
and gneiss of late Proterozoic to early Cambrian age (Goldsmith, et al, 1988).
The subsurface geology at the site was determined by split spoon sampling during well
installations and the soil boring investigation. Site lithology is comprised of three units. The
7

first is a reddish -brown to purplish, slightly micaceous, silty clay extending from grade level
to depths of 7.0-9.5 feet below ground level (BGL). Below this unit is a gneissic saprolite unit
consisting of fine to coarse grained quartz and weathered plagioclase with trace amounts of
biotite and muscovite. Quartz feldspar banding was encountered in the saprolite unit at
depths of approximately 9.5' and 14.5' BGL. Apparent dips of approximately 45° SW were
noted for the banding encountered during test pit excavations conducted as part of the initial
site characterization. These remnant textures are more permeable than the surrounding
saprolite and could act as preferential conduits to the water table. The third and lowermost
unit is a fine to coarse grained weathered garnet -mica -quartz -feldspar gneiss encountered at
depths beginning at approximately 28-30 feet BGL.
Figure 4 presents geologic cross -sections based on soil boring logs. Both cross -sections
indicate that the lithology at the site consists of variably weathered bedrock ranging from clay
to relatively fresh bedrock.
2.1.2 Subsurface Hydrology
The unconfined water table aquifer at the site consists of a quartz feldspar gneissic saprolite
unit. The previously mentioned quartz feldspar banding acts as preferential conduits to the
water table and may have an affect on groundwater flow and contaminant migration. The
bedrock aquifer exists within the underlying gneissic bedrock unit.
The depth to the water table has historically been in the range of 13-23 feet BGL. Table 1
summarizes water level measurements for the site. Water table elevations are depicted in
Figure 5 for July 31, 1996. Groundwater elevation data for various times have shown that the
horizontal gradient varies. Historical potentiometric surface maps have indicated that the
groundwater flow direction is toward the south-southwest. More recent data has indicated
interpreted groundwater flow directions ranging from northwest to northeast. Based upon the
extent of dissolved petroleum contamination in the aquifer in relation to the source area, the
primary groundwater flow direction is believed to be oriented in a southwest direction.
8

Average hydraulic gradients recorded during the development of the CSA ranged from
approximately 0.0036 to 0.0083.
Calculations from the CSA indicate that the bedrock aquifer is characterized by a variable
vertical head gradient. Measurements collected on January 4, 1995 reveal that the bedrock
aquifer has a vertical head gradient of 0.012. Measurements collected on January 18, 1995
indicate that the bedrock aquifer has a vertical head gradient of -0.0043. (Negative head
gradients indicate the tendency for groundwater to flow in an upward direction, while positive
head gradients indicate the tendency for groundwater to flow in a downward direction.) Given
the relative location of the site topographically, it is probably located in an area of recharge
where groundwater tends to have a downward directed head gradient.
2.1.3 Aquifer Characteristics
TEC performed rising head slug tests in monitoring wells MWI, MW2, and MW7. Test results
for hydraulic conductivity ranged from 0.96 ftld in MW1 to 12.3 ft/d in MW2. These values for
hydraulic conductivity fall within the expected range for silty sands to mid -range clean sands
(Freeze and Cherry, 1979).
TEC also performed a 24-hour aquifer pumping test in an aquifer test piezometer (PZI) on
April 3-4, 1996. Test results were reduced using AQTESOLV aquifer test analysis software.
Appendix A contains the test results and software outputs. Based on the analysis, the derived
aquifer parameters are as follows:
Horizontal Conductivity: 2.66 ftld
Vertical Conductivity: 0.21 ft/d
These values are indicative of a silty sand (Freeze and Cherry, 1979) and are consistent with
previous aquifer test data and lithologies observed during the installation of soil borings.
9

2.2 Assessment of Free Product
Free phase product is present in the subsurface, and one of the principle objectives of this
CAP is free product removal. The volume of free product present in the subsurface is
unknown, as is the volume of the release from the former UST system. Based upon the
installation of soil borings and monitoring wells in the vicinity of the well which contains free
product, MW3, the extent of free product appears to be defined. As of July 31, 1996,
approximately 90.25 gallons of LNAPL had been recovered from monitoring well MW3.
Product thicknesses have shown a general decline over the last year. The maximum recorded
product thickness was 2.85 feet on August 11, 1995. On July 31, 1996, the product thickness
was down to 1.45 feet. The estimated extent of the LNAPL is shown in Figure 6. The
interpretation is based upon the surrounding monitoring wells, the source location, and the
observation of remnant subsurface geologic structures. Recovered product is stored onsite
in a vented 55 gallon drum prior to disposal.
2.3 Soil Analyses and Impacts
In addition to the twelve soil borings and test pits installed during the initial site
characterization activities, eleven drilled soil borings were advanced at the site to determine
the horizontal and vertical extent of vadose zone petroleum impact. A complete discussion
of the soil survey is presented in the CSA report. Figure 7 shows soil sample locations and
depicts the extent of soil contamination based on the survey. Contamination is defined by
soils containing greater than 10 mg/kg total petroleum hydrocarbons as gasoline (EPA Method
5030). The presence of free product indicates that the soil impact extends to the water table
in some areas.
10

2.4 Groundwater Analyses
Table 2 summarizes analytical results from groundwater samples TEC has collected at the
site. The most recent results are plotted in Figure 8. The groundwater plume exhibits a
definitive direction of spreading which coincides with the hydraulic gradient.
Groundwater samples have been analyzed per EPA Methods 502.2 + MTBE + 1PE and
3030c/6010 (Lead). Groundwater violations have been detected in MW2 - MW6, MW9, and
MW10. Anaiytes detected include BTEX, MTBE, and isopropyl ether (IPE). Several other
organic compounds, for which no groundwater quality standard applies, have also been
detected; therefore, their detection constitutes a violation.
yLead exceeded the groundwater quality standards in monitoring wells MW1, MW3, MW4, and
'�/ MW6. The highest concentration detected was in monitoring well MW6 on August 8, 1996.
A concentration of 55 parts per billion (ppb) was detected. Given the lack of historical -use of
leaded petroleum products and the lack of correlation between the lead results and the
groundwater plume, it is suspected that the lead appears from naturally occurring minerals .
which are dissolved upon acidification during the sampling process. The lead results are not
indicative of groundwater contamination and are not considered as such.
11

3.0 INITIAL ABATEMENT MEASURES
3.1 UST Closure
The former UST system was permanently removed in April 1994. Approximately 39 tons of
contaminated soil was removed from the former UST basin and several small test pits in the
vicinity of the pump islands. Product lines were pulled from the ground and, thus, not
excavated. The area of excavation was limited to the former UST basin and the test pits.
Given the thickness of the vadose zone, excavation was determined not to be a feasible
option during the UST closure.
TEC submitted a UST Closure, Site Check, and Initial Abatement Report in May 1994. The
reader is referred to that document for detailed information regarding the UST closure
including laboratory reports for confirmation samples, the UST disposal certificate, and the
completed GW/UST-2 form.
3.2 Free Product Recovery
As discussed in Section 2.2, TEC has regularly recovered free product from monitoring well
MW3. The passive recovery option was chosen to provide full time recovery as an interim
measure until a full scale CAP is implemented. The Springs Road Gas House is one of three
sites in the region at which TEC bails product during regularly scheduled rounds (usually twice
monthly). As of July 31, 1996, approximately 90.25 gallons of product had been recovered.
12

4.0 EXPOSURE ASSESSMENT AND CAP OBJECTIVES
4.1 Physical and Chemical Characteristics of Contaminants
Physical and chemical properties of selected compounds are summarized in Table 3.
4.2 Regional Land Use
The site is located in a district of commercial and residential establishments. The vicinity is
bordered on two sides by state routes, Springs Road and Section House Road. These routes
are maintained by the NCDOT. Their right-of-ways abut the property on the northwest and
northeast. The property to the south is occupied by Central Telephone Company. Properties
across Springs Road are residential and commercial. A map of property boundaries and
property owners is provided in Figure 3.
4.3 Site and Regional Water Supply
.3.1 Public Water Supply
v4
Potable water is supplied to the site and the vicinity bythe City of Hic or r utilities department.
Distribution lines run along Springs Road and Section House Road across from the site. The
lines are 12-inch PVC buried approximately 3-4 feet below ground. This depth is above the
water table in the site vicinity.
According to Gene Haynes, Hickory Utilities Director, the City takes its water from Lake
Hickory in the Catawba River basin. The distance from the site to the nearest point on the
lake is 21A miles. The city does not own or operate any wells for water production, nor does
it have any plans to construct production wells anywhere in its district. Appendix B contains
phone logs of various conversations regarding vicinity water supply and other issues.
13

4.3.2 Private _ ater Wells
Mr. Haynes confirmed TEC's findings that some residents in the vicinity use wells for their
primary or secondary water supply. TEC identified 18 residential wells within 1,000 feet of the
site. Of these, ten wells serve as the primary water supply for the residence. Figure 9
depicts the locations of these wells, and Table 4 summarizes information associated with the
wells.
Potable wells #3 and #4 are the most likely to be affected by groundwater impacts at the site.
They are downgradient and 180 feet and 500 feet from the edge of the plume, respectively.
Well #5 is approximately 150 feet upgradient from the edge of the plume. All three are
primary water sources for the residences.
Construction details on wells #3 and #5 are unknown. Well #4 consists of unscreened 24-inch
diameter clay tile to a depth of 48 feet. The bottom is open and the tile joints are not sealed.
Lanny Teague of Geologic Exploration, a local well contractor, told TEC that the bucket well
method of drilling is typical for domestic wells in the area. Generally, a tile casing is advanced
with the borehole until refusal at bedrock. Water production results from leakage through the
casing joints and/or from the bottom of the borehole. Consequently, this type of construction
does not seal the well from water table contamination.
4.4 Potential Human Exposure Pathways
Table 5 summarizes potential exposure pathways and the possibility of occurrence
associated with each pathway. The ratings are specific to the site and are assigned on a
subjective basis with consideration to site conditions.
14

4.5 Potential Effects of Residual Contamination
Residual soil contamination and free product will contribute to groundwater impacts.
Petroleum hydrocarbons dissolved in groundwater will migrate by advective transport and
dispersion. These processes will extend the plume primarily in the downgradient direction.
The most notable result of residual contamination would be to nearby potable wells. The
potential for these exposure scenarios is further explored in the next section.
4.6 Goals and Target Cleanup Concentrations
The goal of the corrective action is to alleviate potential threats to human health and
environmental quality which could arise from contamination at the site. To accomplish this
goal, the corrective action must meet Target Cleanup Concentrations (TCCs). The TCCs are
either compulsory standards established by the NCDWQ or alternate standards proposed by
the responsible party. Alternate standards are based on specific characteristics of the site and
potential receptors. For this site, the TCCs will be based on alternate standards derived from
an evaluation of potential impact to well #3.
TEC conducted an evaluation of risk to the well with the aid of software which solves the
advection-dispersion-reaction equation for contaminated groundwater flow. The method
consists of four basic steps which are summarized below. Detailed calculations and notes are
presented in Appendix C.
4.6.1 Critical Receptor and Exposure Scenario
The first step is to choose the most vulnerable receptor, and the conditions under which it
might be impacted. Since it is the closest well on the downgradient side of the site, well #3 is
chosen. it is 180 feet from the edge of the plume. The well is more cross -gradient than
downgradient, based on groundwater flow and plume geometry, so choosing it instead of well
#4 is conservative. Well #4 is 500 feet from the plume.
15

A water table impact at well #3 could contaminate the well, since there is probably no vertical
seal in the well casing. Vertical flow is not needed to produce an impact. The assumed
impact scenario is horizontal flow directly toward well #3.
4.6.2 Conceptual Model and Choice of Software
Since water table contamination can impact the well, a two-dimensional aquifer representation
is sufficient. The aquifer is assumed homogeneous and isotropic. Aquifer parameters are
determined from the 24-hour pumping test (Appendix A). Aquifer thickness is taken as the
saturated thickness of the unconsolidated zone (8.15 meters). No other aquifer boundaries
are recognized. No surface water bodies are recognized. Pumping from well #3 is ignored.
The mechanisms governing contaminant spreading and concentrations are advection,
dispersion, retardation, and decay. The dispenser islands are taken as the source area.
TEC uses two models which can depict these conditions: BIOPLUME 2 and Princeton
Analytical Models (PRINCE). PRINCE Model 5 is chosen because of its simplicity and ease
of use. This model accounts for 1-dimensional advection, 2-dimensional dispersion,
retardation, and first -order continuous decay. It depicts the release as a line source with a
Gaussian -distributed concentration profile. The line orientation is perpendicular to
groundwater flow.
16

4.6.3 Model Parameters and History Matching
Details regarding input parameters and history matching are included in Appendix C. Some
input parameters are definitely known, while others are unknown. Values for the latter group
must be obtained through best guesses and history matching (a.k.a. calibration).
In history matching, uncertain parameter values are varied so that the model output closely
resembles known, existing conditions. The history of the plume is approximated by the model
over an assumed period of time. The input values, which produce output resembling the
actual site history, are taken as suitable values and are used for future projections.
4.6.4 Future Projections
Having assigned suitable values to all inputs, the plume is projected into the future to
determine the maximum concentration at the receptor, and the time at which it occurs. This
information is used, in conjunction with the maximum concentrations established by 2L
standards, to calculate maximum allowable source concentrations which will produce 2L
concentrations at the well. TCCs are derived from these maximum allowable source
concentrations.
4.6.5 TCC Results and Site Closure
The preceding method requires a number of simplifying assumptions. Conservative
assumptions are made where possible. Additionally, after the maximum allowable source
concentrations were determined, a factor of safety of 10 was applied in the final calculation
of the TCC.
TCCs arecalculated for BTEX and MTBE. They are listed in the following table.
17

Target Cleanup Concentrations
Springs Road Gas House
Hickory, NC
• Compound
TCC (ppb)
Benzene
4,540
Toluene
4,545,000
Ethylbenzene
26,360
Xylenes
2,409,000
MTBE
20,000
Note that only benzene and MTBE have had detected concentrations (in MW3) which exceed
their TCCs. The TCCs for toluene and xylenes exceed the standard solubilities of these
compounds. Thus, no remediation for toluene or xylenes is necessary (although free product
removal must be completed). Benzene and MTBE will be considered the indicator
contaminants for the site.
The first criterion for determining site closure will be complete removal of free product (i.e.
mobile product). The second criterion for site closure will be reduction of concentrations in
the most contaminated groundwater to levels below the TCCs. The third criterion will be the
assurance that residual LNAPL does not cause an increase above TCCs after remediation is
stopped. A period of post-remediation monitoring will ensure this requirement.
Section 6.10 details the termination of remedial actions and additional monitoring associated
with site closure.
18

5.0 REMEDIATION ALTERNATIVES
5.1 Available Remediation Options
Remediation activities address three primary objectives for petroleum -contaminated sites:
source removal, soil remediation, and groundwater remediation. Although the leaking
dispenser system which caused the release has been replaced, free phase gasoline is present
as a continuing source, and vadose zone residuals and dissolved phase compounds are
present at levels which exceed allowable standards. This section will evaluate potential
methods for site remediation.
Options which have been considered for removal of free product include:
• Direct (liquid phase) recovery via pumping;
• Excavation and offsite treatment;
• Vapor -phase extraction.
Options which have been considered for remediation of secondary sources in soil include:
• Vapor -phase extraction;
• Excavation and offsite treatment;
• Natural and enhanced biodegradation.
Options which have been considered for remediation of dissolved compounds in groundwater
include:
• Direct (liquid phase) recovery via pumping;
• Vapor -phase removal via air sparging;
• Enhanced biodegradation via air sparging;
• Natural biodegradation and attenuation.
Tables 6 and 7 summarize the relative advantages and disadvantages of common remediation
options for soil and groundwater, respectively.
19

5.2 Evaluation of Remediation Alternatives
As of January 2, 1996, the NCDWQ is requiring responsible parties seeking reimbursement
from the State Leaking Petroleum UST Trust Fund to evaluate the applicability of 15A NCAC
2L .0106(k) and (I) for corrective action. Paragraph (k) refers to proposal of alternate TCCs
based on risk assessment, and paragraph (1) refers to proposal of remediation by natural
processes. If either of the remediation strategies described in these paragraphs are found to
be applicable at a site, then it must be implemented in order for remediation costs to be
eligible for reimbursement.
5.2.1 Free Product and Groundwater
Springs Road Gas House is not suitable for natural attenuation at this time. Free product is
consistently present on the water table, and potable wells could be threatened by this
continued source. These factors warrant an active, aggressive recovery plan.
The depth and estimated extent of product preclude excavation. Air sparging does not
remove free product and is not appropriate until the majority of mobile product has been
removed (U.S. EPA, 1995 and Nyer, 1996).
Therefore, simultaneous pumping of free product and groundwater with SVE is proposed.
Drawdown of the water table and vacuum application at the well head will hasten product
seepage into the recovery well. Groundwater pumping will provide hydrodynamic control of
the plume.
5.2.2 Contaminated Soil
Excavation is not suitable because of the depth and extent of soil contamination. The costs
for digging and subsequent repair to the site and UST system are prohibitive.
20

A soil vapor extraction (SVE) pilot test has been conducted by TEC, and favorable results
were obtained (Appendix D). Used aggressively, SVE would be effective for both vadose
zone remediation and reduction of free product. A coincidental benefit is the circulation of
oxygenated air to facilitate aerobic degradation by native microorganisms. When applied in
recovery wells, SVE will also hasten liquids recovery.
Thus, SVE will be proposed in conjunction with total fluids recovery.
5.2.3 Discharge of Treated Groundwater
Groundwater recovery and treatment necessitates a discharge. Options investigated for this
site include the following:
• infiltration galleries or injection wells (non -discharge permit);
• discharge to a municipal sanitary sewer network;
• discharge to a surface water feature (NPDES permit);
• spray irrigation.
Spray irrigation is not feasible because of development in the area.
vN.c.
n-discharge is not favored because of the presence of free product and the need for
hydrodynamic control. Hydraulic influence is reduced with a recycling extraction/infiltration
system. Therefore, this method is excluded.
Discharge to a nearby runoff conveyance is both feasible and favorable. Quality Oil Company
would need to obtain coverage under NPDES General Permit NCG510000 (and possibly
permission from the adjacent property owner).
ere is no sanitary sewer system near the site, so this method is not an option.
21

Consequently, the most viable discharge option is by NPDES permit. This method of
discharge will be proposed herein and discussed further in Section 7.0.
22

6.0 PROPOSED CORRECTIVE ACTION
6.1 Overview
The proposed corrective action consists of a three-phase strategy. The first phase focuses
on free product removal. The second focuses on removal of residual contaminant mass via
groundwater pumping, air sparging, SVE, and coincidental biodegradation. The third consists
of post-remediation monitoring.
Free product and groundwater recovery will coincide. Five recovery wells will be installed.
Recovered liquids will be pumped to a shed containing treatment equipment.
Treatment begins with separation of aqueous and nonaqueous phases in an oil/water
separator. From there, groundwater will be treated in an aeration unit to strip volatile
organics. Aerated water will then flow through a bank of pumice filter tanks, followed by two
banks of activated carbon. Treated water will be discharged through PVC piping to the point
of discharge.
SVE will be used for soil remediation and free product removal. Groundwater recovery wells
will double as SVE wells.
Air sparging wells will be used to accelerate soil and groundwater remediation during the
second phase of operation. This stage will commence when the rate of free product recovery
has declined.
Sections 6.3 through 6.10 detail the proposed remediation plan, including design, installation,
and operation. Figure 10 depicts the system layout. Figures 11 and 12 depict the
groundwater and soil remediation system schematics, respectively. Figures 13 through 15
provide details of various components of the system.
23

Appendix E contains notes and results for modeling groundwater flow with Waterloo
Hydrogeologic's FLOWPATH Version 5.11. The model is used to help assess water table
depression and contaminant capture during pumping.
The schedule of implementation will depend on. NCDWQ review of the CAP, equipment
delivery, contractor availability, NPDES permitting, and property access procurement. Quality
Oil may elect to install the system prior to NCDWQ approval, if initial response from the MRO
is good. Otherwise, no action toward installation will be taken until NCDWQ approval is
issued. Specification and bidding may take 6 to 8 weeks. Equipment delivery typically takes
8 to 10 weeks. Installation and startup should take 2 to 3 weeks.
6.2 Checklist of Regulatory Requirements
Paragraph (k) of 15A NCAC 2L .0106 lists the necessary conditions for a site to be suitable
for alternate TCCs. These conditions are summarized in the following list.
1) Provide a comprehensive description of site specific conditions.
2) Provide information on the availability of public water supply for the affected
area.
3) Describe the technical basis for the request for alternate TCCs and the
proposed remediation plan.
4) All sources of contamination and free product must be removed or controlled.
5) Demonstrate that fate and transport of contaminants can be reasonably
predicted and evaluate the future extents of contamination.
6) Demonstrate that the 2L standards will be met no closer than 1 year's travel time
upgradient of an existing or foreseeable receptor, OR
7) If the receptor is a surface water body, demonstrate that a discharge of
groundwater to the surface water body will not cause a violation of surface water
quality standards contained in 15A NCAC 2B .0200.
24

8) Public notice of the proposal must be provided in accordance with 15A NCAC
2L .0114(b).
9) The proposed corrective action plan must be consistent with all other
environmental laws.
The above conditions have been met, are met within this CAP document, or will be met with
execution of this CAP.
6.3 Free Product and Groundwater Recovery
Recovery Wells
A total of 5 wells will be used for groundwater and free product recovery. Figure 10 depicts
the well locations. RW1-RW4 are proposed around the dispensers where free product and
soil contamination are present. RW5 is downgradient of the source area. All wells except
RW5 will be connected to the SVE network.
TEC used FLOWPATH 5.11 by Waterloo Hydrogeologic to simulate recovery well capture
zones. Model outputs are included in Appendix E. FLOWPATH is a simple two dimensional
groundwater flow model which has particle tracking functions with variable retardation. The
particle tracking is used to observe capture zones under various pumping and flow scenarios.
The results of low flow pumping from the proposed well network (0.3 gal/min/well) indicate a
capture zone which encompasses the source area and the majority of the groundwater plume.
A NC licensed driller will install the new wells during the construction phase. The wells will
penetrate the top of the weathered bedrock, so an air rotary drill rig will be needed. A typical
well detail with SVE is shown in Figure 13. All wells will be constructed of 4-inch diameter
PVC and 0.020-inch screen slot. Wells RW1-RW4 shall be screened to accommodate SVE
in the vadose zone. Table 8 summarizes the dimensions and specifications for the proposed
wells.
25

Groundwater Pumps
Recovery wells shall be equipped with submersible pneumatic pumps. The pumps shall be
cycled automatically by an "on -board" controller, They operate on demand at whatever flow
rate is yielded by the well (up to the pump's capacity).
The pumps shall be top loading for total fluids recovery. They shall be of similar make and
performance as Clean Environment Engineers, inc. Model AP-4. (Longyear Evacuator 11
pneumatic pumps shall not be used.)
Air Compressor
Compressed air shall be supplied for pump operation by an electric single-phase 5 hp
(nominal) air compressor. The compressor shall be reciprocating with two -stage compression
and an 80-gallon receiving tank. The tank shall be equipped with an automatic drain valve.
Filters for particulate and oil will be installed in the main air supply line. The air shall first be
filtered through a Type A 5-micron particulate filter. A Type C oil mist filter (100% efficiency)
shall be installed downstream of the particulate filter. The oil filter shall have a minimum
operating pressure of 120 psig and a minimum throughput of 15 scfm with minor pressure
loss.
Pump Placement
Typical depth to groundwater in the vicinity of the dispenser islands is 18-21 feet. The phase
1 objective will be to improve free product collection by a slight depression of the water table.
During phase 1, pump intakes shall be set 0.5-1.0 feet below the water/product interface.
This slight water table depression shall be maintained until the rate of product recovery
declines significantly, after which the intakes will be progressively lowered in approximately
1.0--foot increments. This procedure will be a transition into the second stage of operation.
26

Typical depth to groundwater in the vicinity of RW5 is 15-17 feet. Free product is not
expected in RW5, so the pump will be set to provide 6-10 feet of drawdown. Recovery in
RW5 shall not commence until free product removal from the other wells has been in effect
for 3-6 months.
Z.-Primary Treatment - Oil/Water Separator
From the recovery pumps, liquids shall first flow through an oil/water separator. Free product
will be segregated from water. Product will accumulate in a holding tank for disposal off site,
and water will continue through the treatment system.
The unit shall be of similar make and quality to a Hydro-flo Technologies, Inc. Model DP-4.
This unit is rated for 1-12 gpm and includes a coalescing medium to enhance droplet
formation. The shell of the unit shall be of fiberglass construction. The unit shall be elevated
on a steel stand so that effluent from the separator will flow by gravity into the influent water
sump. The unit will be placed in the open, so a detachable rain -proof lid must be included.
The unit shall be fully accessible from the top.
Transfer System - Influent Sump
Raw groundwater from the oil/water separator will flow by gravity into the influent sump. From
here, water will be fed in batches to the aeration unit. The tank shall be of polyethylene
construction and have a nominal volume of 70-100 gallons. High and low water level switches
in the tank will operate a '/z or 1/3 hp centrifugal pump which will draw from the tank and
discharge to the aeration unit. The transfer tank shall also have a high -override water level
switch, which when activated will close the main air supply to the groundwater pumps. The
pump discharge line shall have a flow valve and visual flow meter for adjusting the feed rate
into the aeration unit.
27

Secondary Treatment - Aeration Unit
The aeration unit shall be a low -profile cascading multi -tray air stripper. TEC used design
software provided by CARBONAIR to specify an aeration unit. The software estimates
hydrocarbon concentrations in treated water under various conditions of flow and unit
capacity. The highest influent concentrations to the unit will occur during phase 1 of
remediation. The flow rate will be low, since the recovery pumps will only slightly depress the
water table.
Input parameters include the chosen air stripper model, a list of contaminants, their influent
concentrations, the flow rate, and water temperature. For influent concentrations, TEC used
values from MW3. These are representative of the highest concentrations on the site prior
to pumping. Influent concentrations should decline sharply after one pore -volume is removed.
Thus, the aeration system is designed for worst -case conditions which will occur at startup.
With 4 trays and a throughput of 3 gpm, the unit will remove 97.7% (mass) of the total volatile
organic compounds (VOCs) considered. This corresponds to a total VOC effluent
concentration of 8,440 ppb. MTBE accounts for 98.8% of this residual. Other considered
compounds include benzene, toluene, xylenes, ethylbenzene, naphthalene, et al. Only
benzene and toluene have standards established by the general NPDES permit, and these
standards are met by the air stripper. Concentrations will be further reduced in tertiary
treatment by activated carbon. The complete model output is provided along with equipment
specifications in Appendix F.
The recommended air stripper is a CARBONAIR model STAT 15 with a 1.5 hp motor (80 cfm
air flow) and 4 trays. The initial design flow rate through the stripper is 3.0 gpm with an air -to -
water ratio of 199:1. This unit has a capacity for 6 trays, so removal efficiency can be
increased with the addition of trays. A sensor measuring dynamic air pressure shall monitor
for low blower output which could indicate a blower problem.
28

Transfer System - Effluent Sump
Outflow from the aeration unit will collect in an effluent sump. The sump may be a separate
vessel or integral to the aeration unit. Figure 11 depicts the sump as a separate vessel. This
tank will operate identically to the influent sump, .with water level switches and pump. The
pump shall discharge to tertiary treatment.
Tertiary Treatment - Filtration and Activated Carbon
The final stage of treatment will consist of particulate filtration through an aggregate vessel
and removal of organic residuals by activated carbon. After the effluent sump, the water line
will split into two parallel branches. Each branch will consist of an aggregate tank filled with
pumice or sand and two 90-pound (nominal) carbon tanks in series. Vessels shall be
constructed for high-pressure operation (50 to 75 psi) and fitted with cam -lock connectors.
A total of 360 pounds of carbon are recommended. This volume should provide sufficient
capacity to reduce concentrations of MTBE and other VOCs to near zero levels. The
estimated minimum working time for a batch of carbon is 30 days. Average working time
should be much longer. Appendix G includes an estimate of carbon usage.
The tertiary treatment system will include an automatic, solenoid -controlled valuing system to
perform backwash on the aggregate tanks. The backwash interval is programmed into the
system controller. The transfer pumps and switching valves will be utilized to reverse flow
through the aggregate tanks to an aggregate trickling filter filled with pumice or sand. The
trickling filter drains into the effluent sump. Each backwash flushes one filter tank, so two
washes are needed to flush the system completely.
29

Discharge of Treated Groundwater
After tertiary treatment, the groundwater shall be discharged to a runoff conveyance. The
discharge shall require coverage under the general NPDES Permit NCG510000. The
discharge line shall be 1-inch I.D. Schedule 40 PVC pipe.
6.4 Soil Vapor Extraction System
SVE Wells
Soil vapor recovery will be conducted through the groundwater recovery wells RW1-RW4.
The method is commonly referred to as vacuum enhanced recovery. The well locations are
shown in Figure 10. A well detail is shown in Figure 13. Table 8 summarizes the dimensions
of the proposed wells.
The installation contractor will connect each well head to the vacuum system. A proportional -
control ball valve shall be installed at each well head. A vacuum gauge will be installed on
the well head upstream of the valve.
Results from the SVE pilot test yield an expected radius of influence (RO1) of 25-30 feet for
a single well drawing 0.5 scfm per foot of screen. The four proposed wells should provide
ample coverage of the soil contamination zone under anticipated operating conditions.
Vacuum Blower and Appurtenances
A blower is chosen by defining the design operating condition(s). Key design factors are the
desired well head vacuum, pressure loss through the vacuum lines, and vapor flow. Notes
and calculations for SVE blower selection are provided in Appendix H.
30

A well head vacuum of 75" H2O is the target design vacuum. This value is chosen from SVE
test results and from feasible operating ranges of economical, suitable blowers. The
maximum estimated pressure loss is 4" H2O for a required blower vacuum of 79" H2O. The
anticipated flow corresponding to this vacuum is 0.6 scfm/ft of well screen. The total screen
length in the vadose zone is approximately 52 feet under static conditions (4 wells, 13 feet per
well). The total vapor flow is 31.2 scfm. Thus, the required minimum capacity of the blower
is 31.2 scfm at 79" H2O.
An EG&G Rotron Model EN523M5L meets the operating requirements. The motor is
explosion -proof, 3.0 hp, single phase at 208-230 VAC. Performance characteristics and
specifications are given in Appendix H. (Note that this blower is designed for higher vacuum,
lower flow applications. For its relatively small motor, it generates higher vacuum with lower
flow capacity than "typical" regenerative models.)
A network of vacuum pipes will connect the wells to the vacuum blower. The blower will be
installed on the concrete equipment pad outside the shed. Upstream of the blowers, a 30-
gallon (nominal) moisture separator drum shall be installed. The drum will have a float switch
to disengage the blower in the event of a high water level.
A spring -loaded vacuum relief valve will be installed at the intake port of the moisture
separator. This valve will prevent overheating of the blower in the event the SVE wells do not
yield sufficient air flow.
A 10-micron particulate filter will be installed upstream of the blower. The filter will be sized
to accommodate 50 scfm with minor pressure loss.
The blower will discharge through a single PVC stack approximately 15 feet above ground
level. (Height will depend on local code.) Off -gas treatment should not be necessary to meet
air emissions requirements. The cutoff for permitting and emissions reduction is 5 tons/yr
VOCs. See Section 7.0 for further discussion of permit requirements.
31

6.5 Air Sparging System
The intent of air sparging is to improve aquifer cleanup through volatilization and enhanced
biodegradation. Air sparging is proposed for phase 2 of operation.
The sparging system is presented here on a conceptual basis. The final proposal and design
will be presented in a system enhancement plan. This plan will be prepared after the second
phase of operation has begun. The current omission of a detailed design allows for the
possibility that air sparging may not be appropriate or necessary. To assess the suitability of
sparging, a pilot test will be conducted in the source area after free product recovery has been
essentially completed. Initial indications suggest low to medium flow sparging will be suitable
once free product is removed.
The sparging wells will be located in the source area. Possible well locations are shown in
Figure 10. The number and locations will depend on pilot test results.
6.6 Treatment System Appurtenances
6.6.1 Concrete Pad
A 4-inch thick (minimum) concrete pad will be poured for mounting treatment equipment.
Nominal slab dimensions are 12 x 25 feet and may vary depending on the footprint of the
chosen equipment shed. A minimum of 4 inches of compacted ABC stone (or other suitable
stone) will be provided as a base. Galvanized wire mesh 4" x 4" shall be placed at mid depth
for reinforcement. The slab will be formed with wood.
The concrete shall have a standard aggregate mixture and a slump of 2-4 inches at pouring
time. The mixture shall have a minimum compressive strength of 3,000 psi at 28 days. The
contractor shall collect three standard cylinders (ASTM C31-69) during pouring. The samples
32

may be tested at the discretion of the supervising engineer. Equipment may be placed and
operated after 7 days.
6.8.2 Equipment Compound
The equipment compound will consist of the equipment shed, components mounted outside
on the concrete pad, and a wooden privacy fence. The oil/water separator and SVE
equipment will be mounted outside. The remainder of the system shall be installed in the
shed.
A dedicated power service pole and meter will be installed for the compound. Single-phase
230 VAC (nominal) power is required. The system control panel will be mounted inside the
shed. A 100-amp breaker box will be included. (The specified vacuum blower requires 88-94
amps for starting. Nominal demand after start is 15 amps. A motor starter or time -delayed
fuse will be required for starting.)
The shed shall be prefabricated with wood frame and aluminum or vinyl siding. It shall be
approximately 10 x 12 feet. The actual dimensions and construction shall be specified by the
equipment contractor to provide adequate space for equipment, storage, and work space.
The shed shall meet all state and local building and/or zoning codes. Fluorescent lights, a
heater, and a vent fan will be included. At least two 110-volt wall receptacles shall be
included.
The shed will be oriented with the entrance at the edge of the slab. Outdoor equipment will
be placed on the slab at the rear of the shed. A chain link security fence will be constructed
around the rear portion of the slab. The fence will be at least 7 feet high. A locking gate will
be provided, and the edges of the fence shall abut the shed.
33

6.6.3 Trenching and Conduits
Pipes and hoses to and from the equipment compound and wells will be installed underground
via shallow trenches. Figure 14 provides a schedule of conduits and hoses. Hoses carrying
water will be buried at a depth of approximately 2 feet below grade. A typical trench detail is
shown in Figure 15.
All SVE pipes, compressed air hose, discharge hose, and connections must be completely
sealed. PVC pipes shall be embedded in the granular base course to at least 1/2 their
diameter. If hoses are not installed during conduit assembly, chase lines for pulling hoses
shall be installed at that time.
Trench backfill shall be native material mechanically compacted in 6 to 8-inch lifts. Backfill
must be free of large cobbles or rubble. Contractor must prevent damage to pipes during
compaction.
Junction boxes will be spaced at key intersections, bends, and well heads to facilitate pulling
hoses through conduits. Boxes in traffic areas must be rated for H2O truck loads and installed
with stone fill and concrete collar as shown in Figure 13 (recovery well detail). Boxes in grass
do not require H2O load rating. They should be 2 x 2 feet and 18-24 inches deep and installed
with an 8-inch wide concrete collar at least 6 inches deep. The collar should be formed with
wood.
34

6.7 System Controls and Safety Functions
6.7.1 Groundwater Recovery System Functions
The influent transfer pump will operate from highand low water level sensors in the sump.
The high switch will activate the pump, and the low switch will deactivate it. As Long as
sufficient compressed air is supplied to the groundwater pumps, they will operate at the well
yield rate. Well yield is controlled by aquifer characteristics and the pump depths. The
pressure of the compressed air supply will be adjusted by regulators in the air supply.
A solenoid -controlled air valve will be installed on the main air supply. The valve shall be two-
way normally -closed. The valve will close and the influent transfer pump will disengage under
the following conditions:
• A high level of product is detected in the product storage tank connected to the
oil/water separator.
• An unusually high water level is detected in the influent sump.
• A low air flow (measured as low dynamic air pressure) is detected in the blower of the
aeration unit. The electronic control shall be calibrated to the sensor for activation
at an air flow corresponding to the recommended minimum air -to -water ratio for the
design conditions.
• An unusually high water level is detected in the effluent sump.
After an alarm/shutdown is triggered, the system shall require a manual reset to continue
operation. The solenoid air valve will close in the event of power loss, halting groundwater
recovery.
35

6.7.2 SVE System Functions
The moisture separator will be equipped with a high water level switch. In the event of high
water in the separator, the vacuum blower will be disengaged. This function requires manual
reset.
6.7.3 Main System Control Panel
Control of the remediation system functions will be accomplished with an electro-mechanical
or programmable logic controller which will integrate monitoring sensors to the operation of
the various motors and control valves. The panel shall have HOA switches for the SVE
blower, the aeration system blower, the influent transfer pump, the effluent transfer pumps,
the compressed air cutoff valve, the air stripper pressure sensor, and the backwash valves.
A master on -off switch will also be included. The main disconnect and fuse box will be located
adjacent to the control panel.
The controller will perform the safety functions discussed above. They are summarized as
follows:
MAIN CONTROLLER SAFETY FUNCTIONS
. CAUSE
EFFECT
High Product Level
Air Valve Closes, lnfl. Pump Stops
High Influent Sump Level
Air Valve Closes, Infl. Pump Stops
Low Stripper Air -Flow
Air Valve Closes, Infl. Pump Stops
High Effluent Sump Level
Air Valve Closes, lnfl. Pump Stops
High SVE Tank Level
SVE Blower Stops
A monitoring and remote notification system will be integrated to the control panel to alert the
appropriate party of any alarm/shutdown mode initiated by the controller. The system will
36

provide notification by telephone message to a preprogrammed phone number. The unit shall
have at least 5 inputs for the alarm shutdown modes described above. A Phonetics, Inc.
Sensaphone Model 1108 or similar unit shall be used.
6.8 Proposed Maintenance Program
6.8.1 System Inspections
Inspection of the following items are suggested. Observations will be made by a qualified
inspector. The frequencies are nominal and may be varied as warranted by experience with
the system.
• Oil/water separator fouling or accumulations Monthly
• Flow through the system Biweekly to Monthly
• Aeration blower operation Biweekly to Monthly
• SVE blower operation Biweekly to Monthly
• Pressure drop across air filters Monthly
• Air compressor oil level Monthly
• Compressor tank automatic drain valve Biweekly to Monthly
• System controls and fail safe functions Quarterly to Semi-annually
6.8.2 Preventative Maintenance
The following tasks and frequencies are suggested as preventative maintenance to prolong
equipment life and prevent accumulation of materials which could potentially cause fouling.
The tasks should be conducted by a qualified inspector or technician.
• Clean sediment and biological growth from OM! separator Monthly
• Remove sediment from sumps Quarterly
• Change oil in air compressor Per Manufacturer's Directions
37

• Change air filter elements in SVE and groundwater systems As Needed
• De -scale air stripper and system piping Semi-annually
• Service groundwater pumps Semi -Annually
The listed frequencies are provided as a rough guide and may prove with experience to be
too long or short. They will be adjusted as warranted.
Oxidation and scaling of dissolved iron is almost certain to occur in the treatment system,
particularly in the air stripper. Flushing with a hydrochloric acid solution will remove iron
scaling and maintain system performance. The required frequency will depend on the severity
of scaling. TEC does not anticipate the scaling to interfere with effective remediation.
6.9 Proposed Monitoring Program
6.9.1 Monitoring Welt Network
Monitoring is conducted to assess the effectiveness of the remediation program, assess the
migration of contaminants, and ensure that discharge requirements are being met. Typically,
monitoring involves collection and analysis of water, soil, and/or vapor samples.
The network of existing wells will be used to monitor groundwater remediation. No additional
wells are proposed.
38

6.9.2 Monitoring Schedule and Parameters
6.9.2.1 Groundwater and Soil Monitoring
First Two Years of Operation
For years one and two, some wells shall be sampled semi-annually beginning at startup.
These wells are MW1, MW2, MW3, MW4, and MW7. Potable wells #3 and #5 (Figure 9) will
also be sampled.
All other monitoring wells will be sampled annually beginning with the first monitoring event.
Recovery wells may also be sampled as needed.
Soil vapor samples will be collected from RW1-RW4 and analyzed for TPHs semi-annually.
The vapors will be collected from the vacuum line at each well head while the system is
operating. Samples will be drawn into tedlar bags with a hand vacuum pump, or some other
NCDWQ-approved sampling procedure will be used. Samples will be analyzed for total
petroleum hydrocarbons.
Third and Subsequent Years
During the third and subsequent years, monitoring will occur semi-annually or annually as
needed based on the rate of observed changes in pollutant concentrations and extent.
The wells to be sampled will be determined based on information gathered in the previous two
years.
Soil vapor samples will be collected from RW1-RW4 and analyzed for TPHs semi-annually.
The vapors will be collected from the vacuum line at each well head while the system is
operating.
39

Monitoring Parameters
Each groundwater monitoring event will consist of the following measurements and analyses:
• water level measurements;
• product thickness measurements;
• lab analysis by EPA Method 502.2 with MTBE.
A monitoring report will be prepared and submitted to the MRO of the NCDWQ for each
monitoring event. The report will include the following when applicable: text description of
field activities, discussion of results, water level map, dissolved concentrations map,
tabulations of field and analytical data, and copies of laboratory reports.
6.9.2.2 Remedigtion System and Discharge Monitoring
Effluent from the groundwater remediation -system will be sampled and analyzed to meet
requirements of the NPDES permit. Currently, this requirement is for monthly sampling.
Samples will be analyzed by Method 502.2 + MTBE.
Samples of water at various stages of treatment may also be collected to determine the
effectiveness of the remediation system. No schedule is proposed for these samples. They
will be collected at the discretion of the operator.
6.10 Termination of Remedial Actions
Remediation activities will proceed until ail recoverable free product has been removed and
groundwater concentrations meet the TCCs. Completion of product recovery will be
determined by measuring levels of product in the recovery wells. Measurements will be made
under static conditions at least one week after all pumping and vapor extraction has stopped.
Product will be identified with product gauging paste.
40

if no product is detected and groundwater concentrations meet the TCCs, the system will be
shut down and the site monitored for one year. Wells will be gauged for product and samples
collected on a quarterly schedule. After a year, if product, groundwater exceedences, or soil
contamination have not been observed, petition will be made for site closure, and the system
will be dismantled.
If either product or exceedences occur during that year, treatment will resume.
If all product is removed before concentrations meet the TCCs, treatment and monitoring will
continue until concentrations decline below the TCCs, as defined under the asymptotic limit
rule, 15A NCAC 2L .0106(m). The monitoring frequency may be increased to quarterly during
the final stage of remediation.
For soil remediation, a soil survey will be conducted during the final monitoring phases
described above. A minimum of five soil samples will be collected in the vadose zone below
8 feet and above the capillary fringe. The samples will come from the source area near the
dispensers. They will be tested for TPHs by Method 5030 or another approved method(s).
If the arithmetic mean of the results falls below the action limit, the soil remediation will be
deemed complete. Otherwise SVE will continue. The action limit will be determined by a Site
Sensitivity Evaluation or risk -based procedures which will be in effect at that time. (For the
calculation of the mean, the value of the detection limit will be used to represent samples with
non -detectable concentrations.)
6.11 Estimated implementation Costs
Appendix I details the estimated costs for implementation of this CAP. Implementation will
consist of equipment purchases, installation/construction, operation/maintenance, and
monitoring.
41

The estimated cost for equipment, installation/construction, and drilling is $91,816. The
estimated cost for 4 years of operation is $12,187. The estimated cost to implement the
proposed monitoring plan for 4 years after startup is $59,461. These costs are based on
vendor bids, previous job costs, and UST trust fund task costs. The total estimated cost to
install and operate the system to completion (based on 4 years) is $163,464. Note this cost
does not include costs for purchasing and installation of the air sparging system.
42

7.0 PERMITS AND NOTIFICATIONS REQUIRED
In accordance with 15A NCAC 21_ .0114 (b) Notification Requirements, parties that submit a
request under Rule .0106 (k) are required to notify the focal Health Director, the chief
administrative officer of the political jurisdiction in.which the contaminant plume occurs, and
all property owners and occupants within or contiguous to the area underlain by the
contaminant plume, and under the areas where it is expected to migrate. Notification consists
of a description of the corrective action and the reasons supporting it. A sample notification
letter and copies of the certified mail tickets are included in Appendix J. Those parties being

A permit will be required to install the recovery well. The permit will be obtained from the
appropriate NCDWQ office at the time of installation.
The proposed method of discharge will require coverage under general NPDES Permit
NCG510000. A copy of the Notice of Intent (short form) is included in Appendix K. If the
existing storm sewer along Springs Road is not accessible for discharge, a separate discharge
line will have to be installed from the site to the drainage ditch (see Figure 2). In the latter
case, a right -of -entry agreement with the owner of the Central Telephone facility will be
required in addition to the NPDES permit. Upon installation of the remediation system, the
NPDES permit and any access agreements will be obtained.
Currently, an air discharge permit for the air stripper and SVE exhausts is not required unless
the long-term average emission exceeds 5 tons of VOCs per year. This cutoff roughly
corresponds to 1,500 gallons of gasoline. Based on past experience, it is unlikely that VOC
emissions will exceed this value. It is possible that at startup, the short-term average VOC
emissions will exceed the 5 ton/yr average, but the emissions should decline substantially
after the initial startup phase.
An engineer's certification will be obtained after construction to verify that the CAP has been
implemented according the intent of the plans and specifications. A licensed North Carolina
engineer will provide the certification.

8.0 LIMITATIONS
TEC has presented a thorough effort to develop a corrective action strategy which will
alleviate possible threats to human health and the environment. The chosen strategy is based
on the available data. The opinions and conclusions stated in this report are in accordance
with accepted engineering and hydrogeologic practices of the field at this time and location.
No warranty is implied or intended.
The focus of work at this site is limited to the investigation of petroleum hydrocarbons as
gasoline. The results do not imply that other unforeseen adverse impacts to the environment
are not present at the facility, although none have been detected. In addition, subsurface
heterogeneities not identified during the current study may influence the migration of
groundwater or contaminants in unpredicted ways. The limited amount of sampling and
testing conducted during the assessment can not practically reveal all subsurface
heterogeneities. Furthermore, the subsurface conditions, particularly groundwater flow,
elevations, and water quality may vary through time.
The modeling efforts were conducted using mathematical techniques which simplify the
complexity of the subsurface environment. These simplifications are typical of modeling
applications and are necessary to solve complex mathematical formulations using limited data.
Consequently, model predictions are based on these simplifications. Error can be introduced
into model predictions when actual conditions depart from the simplified representations used
in the model. This uncertainty is balanced with a high factor of safety used in calculating
alternate cleanup standards.

-AutoPumpO Systems ;
COST/PERFORMANCE ADVANTAGES
The AutoPump® is the centerpiece of CEE Down -well Controllerless Systems. This
patented design is unique in the industry, being the first controllerless remediation pump on
the market back in 1986. Following are a group of advantages the CEE AutoPump has that
has made it the marketplace leader.
YEARS OF FIELD PROVEN RELIABILITY
AutoPumps have been on many different kinds of sites since 1986, pumping millions of
gallons of fluid. CEE has been successfully installing the AutoPump on sites all over the
world for close to a decade, and its proven track record results in lower operation and
maintenance costs. This extensive experience has resulted in many improvements and
refinements over the years which make it the pump of choice in many applications.
PNEUMATICALLY OPERATED
Pneumatics are intrinsically safer than electric systems that can shock; spark, or ignite fires.
The AutoPump is pneumatically operated, and thus safer and not subject to the strict electrical
codes for explosion -proof designs. This reduces system design logistics, initial capital
expenditures, and risks of injury.
AUTOMATIC CONTROLLERLESS OPERATION
The AutoPump has no timers, bleeders, bubblers, or other external controls to maintain or
calibrate. All governing parts are placed within the main pump body, reducing
operating/training costs commonly associated with timer adjustment alterations made by
maintenance personnel. The pump turns on and off automatically and only uses air while
pumping. Without bubblers and bleeders, operating and maintenance costs are reduced: air
consumption is significantly lower, bio-growth is not a major problem, and the pump can
operate with a vacuum on the well. This results again in lower training and maintenance
costs associated with disassembling and cleaning equipment
DEEP -WELL PUMPING 1N 2-INCH DIAMETER WELLS
The AutoPump can pump from wells as small as two inches (and larger) in diameter and from
depths of 300 feet. In some cases, the AP-2 is used in monitoring wells for remediation vs.
drilling larger diameter wells. As a result, costs are greatly reduced.
AIR CONSUMPTION
The AutoPump only uses air while pumping. Unlike systems that rely on bleeding air sensors
or timers which pressurize and depressurize the air hoses for each stroke, the air hoses
remain pressurized to the pumps at all times. Air compressor power consumption,
compressor filter maintenance, and thus operating costs are substantially reduced.
DESIGNED TO HANDLE HARSH WELL AND FLUID CONDITIONS
The AutoPump can pump solvents (such as MEK, Butylacetate, Acetone, Toluene, etc.),
fuels (gasoline, diesel, jet fuels, etc.), and leachate with wide ranges of pH (1-12) and
dissolved contaminants. The AutoPump® can pump boiling water and diesel at steam
injection sites with temperatures up to 212°F.
[phone] Clean Environment Equipment - rev. 3 2b-1

AutoPumpO Cost/Performance Advantages (Cont'd)
TOUGH AIR VALVES
Durable stainless steel air valves that can pass liquids as thick as 90 weight gear oil without
fouling are used with the AutoPump . The air valves can handle reverse flow and submersion
for long periods of time. Unlike pumps with bubblers or bleed hoses, there are no problems
with start up, clogging, and failure under these difficult conditions when using the AutoPump.
This results in less down -time, training & maintenance costs, and repair costs.
AS FEW AS 2 CONNECTIONS TO THE SURFACE
The AutoPump® has only three hoses to attach: air input, air exhaust, and fluid discharge.
Under normal installations, only 2 need exit the well —air input and fluid discharge (air exhaust
can be vented to the well). When compared to bleeder, timer, or bubbler -controlled pumps,
this results in Tess initial costs related to installation, operation, and future maintenance.
ONLY FLUID THROUGH THE DISCHARGE HOSE
Because the AutoPump has no timers, air is not blown out of the fluid discharge. This is a
common fault of timer -driven systems. The AutoPump's smooth, consistent operation keeps
air use, emulsification, oxygen -driven deposits, and the chance of electro-static build-up at a
minimum.
FREEZING WEATHER RESISTANT
Because there are no surface or external controls, freezing temperatures do not affect the
pump's performance as severely as other designs.
INDUSTRIAL GRADE HOSING
AutoPumps typically are used with only high-grade, industrial, color -coded hoses with no -mix,
and locking sleeve quick -connect fittings. As a result, the Down -well Controllerless AutoPump
System is a "user-friendly" system that can be assembled and disassembled by a novice.
EASILY EXPANDABLE
Additional pumps can be added to a system by teeing them to the compressed air line —there
are no problems associated with the need for additional sensors, controls, filters, or regulators.

Cantrultertess AritaPump®' System
SPECIF 1 C AT I ONS
The AP-4/TL System is a fixed intake, free floating product and water, automatic Total Fluids
Recovery System that recovers fluids from depths up to 300 feet and flow rates over 10
GPM. Able to function in wells 4 inches and larger, this controllerless system works without
the use of any external controls, bleeders, or bubblers. The AP-4/TL System consists of an
AutoPump (an automatic, controllerless, air -displacement pump), filter/pressure regulator,
hose and hardware package, and well cap.
METHOD OF OPERATION
The AutoPump (Model AP-4/TL) is initially placed in a recovery well(s) and its top inlet
submerged below static groundwater conditions. Given a regulated supply source of
compressed air, the pump is cyclically emptied in response to being filled through the top inlet.
This allows floating product to enter and be pumped.
As the pump fills, an internal float rises until it comes in contact with an upper stop that is
connected to a mechanical lever assembly which simultaneously opens an air supply poppet
valve and closes an air exhaust poppet valve. As a result, air pressure builds up within the
pump body and displaces the fluid contents up and out of the pump through a discharge ball
check valve.
As the discharge cycle progresses, the float falls, and prior to being completely empty, the
float comes in contact with a lower stop that triggers the lever/valve assembly again; closing
the air supply poppet and opening the air exhaust poppet. The pressurized air then
exhausts and the pump is allowed to refill itself, thus beginning a new cycle.
This cyclic operation continues automatically as the groundwater level is drawn down within
the well.
When the AP-4/TL "catches up" with the well, the fluid level in the well is maintained at the
top inlet, and the Auto Pump is pumping at a rate equal to the well yield for that specific draw
down level.
CONTROLLERLESS PUMP
The AutoPump Model AP-4/IL is a submersible top -loading pump that :
• Is air -displacement in type, requiring only a regulated compressed air source.
• Requires an operating pressure of 5 psi above static head.
• Requires no external remote control panel or satellite controllers.
• Self -adjusts discharge flow rate automatically to match well yield (up to the pump's
capacity).
• Uses air only when discharging fluids, therefore, air usage is optimized.
• Functions under positive or negative (vacuum) pressure environments. -
• Does not require clean, dry air to function properly and pumps particles up to 1/8 inch
in diameter without problems.
• Can operate on contaminated air.
• The air valve can pass 90 weight gear oil without fouling.

remote.
• A single air/filter pressure regulator unit can be used for a multiple well site.
• Consists of a single -stage, 5 micron particulate filter contained in a metal bowl.
• Includes a float -operated condensate drain.
• includes a pressure regulator that is adjustable from 0-125 psi and is rated for 250 psi.
• Allows for the adjustment of supply air pressure to that value necessary to operate
the pump and overcome discharge head requirements.
• Is typically provided with locking -sleeve, hydraulic grade brass quick -connect fittings.

The standard well cap provided with the AutoPump model AP-4/TL:
• Provides a support for the pump in the well.
• Consists of a Schedule 40 PVC cap.
• Has apertures for fluid discharge and air supply hoses, and pump support rope.
• Provides a "slip -fit" over the recovery well casing.
• Offers protection from debris failing into the recovery well.
• Is not rated for pressure (or vacuum) use. (See Section "8" for vacuum applications
and other types of well caps.)
• Well caps larger than 4 inches are also available.
FLOW RATES
The maximum values below are based on minimal discharge head.
• Standard AP-4/TL: 0 to over 10 GPM (See Performance Curve)
• Short AP-4/TL: 0 to over 9 GPM (See Performance Curve)
The volume per cycle varies depending upon the ratio of the air inlet pressure to the total
developed head (TDH). The closer the TDH is to the air inlet pressure, the closer the volume
per cycle is to the bottom of the range shown below.

Standard AP-4/TL
0.58 to 0.78 gallons I
0.65 gallons
Short AP-4/TL
0.23 to 0.34 gallons ; 0.25 gallons
All figures above are dependent on site specific conditions under which the pump is
operating.
SYSTEM REQUIREMENTS/PARAMETERS
The AP-4/TL Total Fluids Recovery System:
• Since air is used "on -demand," air consumption is directly proportional to well yield.
Typically, 0.4 to 1.0 scf of air per gallon yield is adequate. (Check air consumption
chart) Please contact CEE for assistance in compressor sizing.
• Operating pressure is typically set at approximately 20-40 psi above the static head.
• Typically, male thread adapters (NPT) are included with surface quick -connects for
connection to trunk lines or headers for both fluid discharge and air supply.
• Can be applied in cases of up to 300 feet water column, static head. See curves.
• Can be used in 4-inch diameter or larger recovery wells.

DESIGN CRITERIA
While other manufacturers are still using outdated information from chapters 3 & 5 of the API manual on disposal of
refinery wastes, API bulletin #1630, first edition, May 1979, HYDRO-FLO uses the Latest design criteria as defined
by the American Petroleum Institute, API publication ► 421, Feb. 1990, The Design & Operation of 011/VVater
Separators. Gallons per minute, specific gravity of the "aqueous" phase, specific gravity of the "oil" phase, oil droplet removal
rate, viscosity of the wastewater, wastewater temperature, cross sectional velocity, etc....all of these factors have an impact on the
operation of your separation system. Don't rely on old and outdated information. Come to Hydro -Flo for separators designed
around today's information and technology.
OPERATION
INFLUENT DIFFUSION CHAMBER
The flow enters the separator submerged, through an influent
diffusion chamber. Dispersion across the depth and width of
the separation chamber is achieved through the use of a
non -clog diffuser. Heavy solids fall out of suspension here
and are channeled to the sludge collection chamber.
SEPARATION CHAMBER
The separation chamber is fitted with DYNA-PAC cross
corrugated coalescing media. The pack creates a uniform
cross -sectional resistance which further helps disperse the
flow throughout the separation chamber. The sinusoidal flow
of wastewater through the pack serves to promote intimate
contact between the oil droplets and the plate surfaces. The
coalesced oil has the least restricted path to exit the waste
stream, and slides to the top of the pack on the surfaces of
the plates. Solids encounter a 60 degree angle of inclination
which is optimum for solids settling. The solids slide down
the plates gathering both mass and velocity as they near the
bottom of the pack and • drop into the sludge collection
chamber.
SLUDGE COLLECTION CHAMBER
The sludge collection chamber is located directly beneath the
coalescing media pack and provides ample storage capacity
for the settled sludge. The sides of the chamber are sloped
at 45 degrees to insure easy and complete removal of the
settled sludge.
OIL REMOVAL
The separated oil accumulates at the surface of the
separation chamber where it displaces the water. As the oil
layer increases, oil will automatically spill over into the
adjustable rotary pipe skimmer. The oil can then flow into the
integral oil reservoir for temporary storage. The oil can then
flow by gravity or be pumped automatically to remote storage
tanks.
EFFLUENT CHAMBER
The aqueous phase leaving the DYNA-PAC flows under the
oil retention baffle and up over an adjustable effluent weir,
which will maintain the liquid level throughout the separator.
As the clean water passes over the effluent weir it enters the
effluent chamber where it can either flow by gravity or be
pumped automatically to the MSD or further processing.
REMOVABLE LID
The entire separator is covered with a removable lids. The
lid is held in place with 12 tum, quick release latches and
gasketed with industrial duty "D" shaped gasket material to
ensure a vapor tight seal.

HYDRO-FLO TECHNOLOGIES, INC.
HYDRO-FLO uses the latest design criteria as defined by the
American Petroleum Institute, API publication #421, Feb. 1990,
The Design & Operation of OWWater Separators.
Gallons per minute, specific gravity of the "aqueous" phase, specific
gravity of the "oil" phase, oil droplet removal rate, viscosity of the
waste water, waste water temperature, cross sectional velocity, etc. -
ail of these factors have an impact an the operation of your separation
system. Don't specify or buy an improperly designed separator. Call
HYDRO-FLO today and have a separation system designed for your
unique application.
HYDRO-FLO uses different media sizes to best solve your
separation problem.
What is the makeup of your waste water? Does it consist of low
quantities of suspended solids and large quantities of highly viscous
oils? Does it consist of high quantities of heavy suspended solids and
low quantities of light viscosity oils? At HYDRO-FLO we select the
media based on your situation. Our media will give you the best
possible maintainability without sacrificing performance.
HYDRO-FLO incorporates the features you request.
In addition to our standard features (influent diffusion chamber with
non -clog diffuser, integral sludge collection chamber, rotary pipe oil
skimmer, effluent chamber with sheen baffle, etc.) HYDRO-FLO has
incorporated many features recommended by our customers. (Look at
the list below and see just how much more you get with a HYDRO-
FLO separation system)
We supply heavy duty lids with industrial duty gaskets for a vapor
tight seas. Along with that come quick release 1/2 tum draw latches
for ease of maintenance.
We incorporate heavy duty rotary unions with zerk fittings into our
rotary pipe skimmer. Also, we use industrial duty fittings and
hardware for years of trouble free operation.
We supply integrally molded tank fittings (instead of bulkhead fittings
with gaskets). This is a more expensive method of fabrication, but it
eliminates leaks from gasket compatibility problems.
We supply an integral product recovery tank/pump sump for the
intemal storage of all recovered product. This eliminates the need for
external storage and additional secondary containment.
We supply an integral sludge collection hopper for the storage and
easy removal of accumulated- sludge. The removal of accumulated
sludge is important for the proper operation of this equipment and a
hopper is the best method for the storage and removal. We are
currently the only manufacturer of molded fiberglass separators
who incorporates this feature!
THE: COMPETITIO N
The: competition uses arbitrary design c.-iteria.
•
Some irlanufacturers use two gallons per minute per cubic foot of
media supplied;,.:Others..,use, 1.0..gallons wr rth:af capacity per gallon
permrnu#e. Arid still.others>srse S tn'EQ r}iinetes'oyerall retention time
• based on "their feel for the project" None of`'hese factors are
• legitimate sizing -criteria.. Sometimes theyvrork; but most often their
performancels,inadequate at.best. Don't be: fooled•. by arbitrary design
criteria. Nave your equipment designed' properly from the start with
HYDROFLO '
The:competltiori only offers':orie,stie:of media.regardless of design
considerations:
Different :applications require different types of media. Filter
manufacturers offer different :size filter eliminates. Plate
sedimentation' equipment manufacturers offer different spacing an
their pack: assemblies. If your current supplier of oilAvater separation
equipment -::doesn't offer different media for different applications,
come to 'HYDRO-FLO and allow us -to recommend' the correct media
for your application.
The competition doesn't!
Most manufacturers incorporate features based on what other
suppliers offer. They are more concerned with keeping pace with
them than they are with supplying what the customer wants.
Sometimes this thinking eliminates just the feature that you need. .
They supply inexpensive gaskets,..normally used to seal home
doors and windows, only as an option. The separators incorporate
cumbersome nuts and bolts for.lid removal.
They: :use?;general duty compression..couplings-with consumer
grade:hardware. For example-they'use a•cad plated bolt dipped in
vinyl for a control handle on, their rotary:pipe skimmer.
They offer bulkhead sittings :with gaskets. The gaskets swell and
deteriorate over. time and :the fittings leak. They are a high
maintenance:item that have .to be replaced an a -regular basis:
They cio not provide for internat.storage.
The competition; either offers :no: provision forthe-collection and
removal of accumulated sludge; or they:have.a flarbottom with a pipe
maniifold:•'This is. not an effective: -method for.`.the.removal of sludge.
The pipes. tend to plug up and- there is little space for sludge to
accumulate before fouling out the pack.

Sensor model.
WE (Weight, External): The WE has an adjustable weight attached
to the cable and is used in applications where the float is suspended from
above.
ADVANTAGES
• Heavy-duty mercury tilt switch is epoxy
encapsulated in non -corrosive PVC plastic
float housing.
• TWO-YEAR LThiITED WARRANTY.
APPLICATIONS
Sensor Floats are frequently used in sewage
systems, irrigation systems, and in other water
systems.
NORMALLY OPEN (Pump down)
application: The mercury float switch closes
(turns on) when the float tips a few degrees
above the horizontal position and opens (turns
off) when the float drops a few degrees below
the horizontal position.
NORMALLY CLOSED (Pump up)
application: The mercury float switch closes
(turns on) when the float drops a few degrees
below the horizontal position and opens (turns
off) when the float tips a few degrees above
the horizontal position.

STAT Series
Sieve Tray Aeration Technology
Carbonair's exclusive STAT series represents the
best choice for low profile air strippers with design
simplicity, flexibility and high performance.
In Carbonair's STAT units, the water and air are
contacted in step -wise fashion on multiple trays. The
water enters at the top and flows across each tray. The
air passes upwards through openings in the trays, then
bubbles through the water to form "a surface of foam"
which provides extreme turbulence and excellent
volatilization. Since the water in Carbonair's STAT
units flows horizontally across each tray, the traveling
path length of water and the required removal efficiency
can be achieved by increasing both the number and
length of the trays. Therefore, the STAT units provide
much lower tower height than the conventional
packed towers.
Another advantage of Carbonair's STAT units is
that air and blower power consumption are effectively
utilized since a single air stream passes through every
tray before exiting the tower. As a result of minimal
air flows, the organic contaminants are concentrated
and effectively removed by vapor phase carbon.
Ec
Low tower height yields numer-
ous other advantages: rapid installation,
easy winterization, inconspicuous
appearance, easy shipping and easy
maintenance. The STAT unit also re-
duces the potential for fouling since it
contains no packing media and provides
an extreme turbulent condition.
Carbonair's STAT units are avail-
able with a number of plate configura-
tions, blowers and controls, and can
achieve removal efficiency up to 99.99%.
OPTIONS
Explosion -proof controls.
Discharge pump.
Well control.
Off -gas carbon.
Humidity control.
Carbon polish.
Winterized enclosure.
FEATURES
The low air flow and minimal tower height
make the unit ideal for off -gas treatment
The compact unit can be installed in a few
hours.
Controls include motor starter, level switch,
air pressure gauge and air pressure switch-
Panel comes with blower, manual -off -
automatic switch and alarm lights.
Computer modeling customizes the system
for optimum air flow, number and size
of trays.

Main System Control Panel
The GeoPure Continental's Main System Control Panel integrates all system components on a
site. The control panel provides a maunal-off-automatic switch and a power on light for each
pump. High Ievel alarms are provided where required and have an indicating light on the
panel door. All alarms are interfaced to turn off the recovery pumps. The control panel
automatically restarts the recovery pumps when all alarms are satisfied. Custom designs are
available. All GeoPure Control Panels are UL approved.

3. Exhaust Fan
4. Air Inlet Vent
5. Heater
6. Hasp for padlock on 44" door
7. Florescent Safety Light
8. GFCI Receptacle with Water Proof Cover
Our buildings are constructed on 4 x 6 pressure treated pine skids; two skids on 8' wide
buildings and three skids on 10' wide buildings. Building walls are 7' high. Pressure
treated floor joists are attached to skids on 24" centers and cross -nailed. Joists are then
decked over with 3/4" T & G underlayment plywood. Wall studs, ceiling joists, and
rafters are 2 x 4 spruce with a 1 x 4 belt rail dadoed into the backsides for rigidity. The
exterior of the buildings are sheeted with various profiles of .017 - .019 aluminum
sheeting. The aluminum is attached to the side framing with #8 x 3/4" weather resistant
screws. The top sheeting is attached with #8 x 1" weather resistant screws with bonded
neoprene washers. All moisture sensitive seams and joints are caulked and/or putty taped.
