Notes by Ed Watson: - -
Groundwater samples for this system are able to be collected at influent, effluent and mid -point
sampling ports. The system is secured, clean and well kept.
The system is supplied by twelve Recovery Wells (RWs) that transfer influent water to the remediation
system. through a trenched network. Inspection of the RWs revealed the presence of water in the well
gallery boxes' of the two wells that were viewed during the site visit. The recovery well. galleries need to
be adapted to prevent surface water from rainfall to be allowed to enter into the gallery box as were are
unable to authorize this type of water from being allowed to enter the recovery wells.
The outfall for this system enters into an unnamed tributary of Fites Creek a class WS-IV CA stream in
Subbasin-03-08-34 of the Catawba River basin. We were able to observe the discharge and there was
no presence of foam, solids or odors at the outfall.

reviewed during the inspection, revealed the presence of water in the well gallery boxes of
the two wells. The recovery well galleries need to be adapted to prevent surface water from
rainfall to be allowed to enter into the gallery.

Representatives from the Mooresville Regional Office (MRO) of the Division of Water Resources
(DWR) visited the remediation facility to perform an inspection of the general permit issued for
this site. We met with Joe Vickers and Frans Lowman P.G. of ATC who operator -and maintain
the remediation system. Groundwater samples for this system are able to be collected at
influent, effluent and mid -point sampling ports. The system is secured, clean and well kept.
The system is supplied by twelve Recovery Wells (RWs) that transfer influent water to the
remediation system through a trenched. network. Inspection of the RWs revealed the presence
of water in the well gallery boxes of the two wells that were viewed during the site visit. The
recovery well galleries need to be adapted to prevent surface water from rainfall to be allowed
to enter into the gallery box as were are unable to authorize this type of water from being
allowed to enter the recovery wells.
The outfall for this system enters into an unnamed tributary of Fites Creek a class WS-IV CA
stream in Subbasin 03-08-34 of the Catawba River basin. We were able to observe the
,discharge and there was no presence of foam, solids or odors at the outfall.
It is evident that ice is being used by the receiving temperature reported by the lab. However, a
suggestion was made to make comment on the Chain of Custody (C.O.C.) to indicate ice as the
method of preservation for the samples that are being collected for lab analysis.
Overall the site was in good condition and found to be in compliance with the permit.
This permit will expire on September 30, 2016. Permit renewal application has been submitted
for this site.
Permit is effective until Sept. 30, 2016. Application for permit renewal has been submitted.

NCDENR Incident No. 10848
Risk Classification: High #(HI80D)
ATC Project No. 89.75118.2748
Dear Mr. Parker:
ATC Associates of North Carolina, P.C. (ATC), on behalf of Phillips 66, is submitting this letter
for effluent water sampling results at Circle K 8379 (RM #2748). The system is located at 101
Belmont -Mount Holly Rd, Belmont, NC 28012. The attached Figure 1 indicates the site location,
and Figure 2 shows the treatment system and discharge location.
A quarterly influent and effluent sample was collected on April 15, 2014. The samples were sent
to Lancaster Laboratories and each set of samples were analyzed by EPA Method 6200B for
volatile organic compounds and EPA Method 504.1 for low detection of EDB. The effluent
sample was also analyzed by EPA Method 3030C for lead and EPA Method SM-20, 2540D for
total suspended solids (TSS), as required by the NPDES permit.
The system effluent samples contained no impact above discharge limits, with the exception of the
effluent sample from April 15, 2014 for TSS, at 47.6 mg/L, which exceeds the quarterly daily
maximum average specified by the NPDES permit of 30 mg/L. To assure a quarterly daily maximum
average within acceptable limits, ATC conducted system observations which found poorly seated
100 micron bag filters in the filter housings. ATC replaced and properly seated 1.0 micron bag filters
in filter housings and collected two samples on May 1, 2014. The additional samples were analyzed
for TSS, and concentrations were below 1.0 mg/L for each sample. Based on the mean value of the
sample concentrations the quarterly daily maximum average is much less than the NPDES permit
limit. However, another sample will be collected in May 2014 to assure continued TSS
concentrations do not exceed the NPDES limits for the remainder of the second quarter of 2014. We
will return to quarterly monitoring in June 2014, provided future analytic results do not indicate the
need for a more frequent schedule.

Subject: NPDES Permit NCG510000 renewal
Certificate of Coverage (CoC) NCG510390
Store #8379 site
Gaston County
.Dear Permittee:
The facility listed above is covered under NPDES permit NCG510000 for discharge of remediated
groundwater_ NCG510000 expires on September 30, 2006. Federal (40 CFR 122.41) and North Carolina (15A
NCAC 2H.0105(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 requirement, 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 remediatiori system will occur after September 30, 2006, your CoC must be
renewed. Discharge of wastewater without a valid permit would violate North Carolina General Statute 143-
215.1; unpermitted 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.
Sincerely,
Charles H. Weaver, Jr.

Dear Permittee:
The Division received your request for renewal of the subject Certificate of Coverage (CoC) on March
16, 2006. The revised General Permit was signed on September 20th, 2006 and takes effect October 1, 2006.
Accordingly, we are forwarding the attached CoC to discharge under NCG510000. This CoC is issued
pursuant to.the requirements of North Carolina General Statute 143-215.1 and the Memorandum of .
Agreement between North Carolina and the US Environmental Protection agency dated May 9,;1994.
A copy of the renewed General Permit is enclosed, as well as an updated Technical Bulletin. The .
Technical Bulletin summarizes the changes from the .previous version of NCG510000. If any parts,
measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you
have the right to request an individual permit by submitting an individual permit application. Unless such
demand is made, this Certificate. of Coverage shall be final and binding.
The CoC is not transferable except after notice to the Division.. You must notify the Division if you .
sell or otherwise transfer ownership of the permitted facility. The Division may require modification or
reissuance of the CoC.
If your facility ceases discharge of wastewater before the expiration date of this permit, contact the
Regional Office listed below. Once discharge from your facility has ceased, this permit may be'rescinded.
This permit does not affect the legal -requirements to obtain :other permits which may be required by the
Division of Water Quality, the Division of Land Resources, Coastal Area Management Act or any other

RE: NPDES permit for NCG510390
Brandon — it's the permittee's responsibility to meet all effluent limits and prevent any instream violations of water quality standards. If
you and the permittee believe that removal of the activated carbon from the treatment system will not cause limit violations or instream
impacts, you may proceed.
Document on what date the activated carbon is removed, as well as any changes in discharge characteristics post -removal.

1.0 BACKGROUND INFORMATION
1.1 Purpose
Circle K Stores Inc. (Circle K) is currently operating a soil and ground water remediation
system installed for corrective action at the Circle K Store #8379 in Belmont, North Carolina.
The remediation system is comprised of four ground water extraction wells, an oil/water
separator, a low profile air stripper, pretreatment filters, and carbon absorption canisters. A
vacuum is applied to the extraction wells through a regenerative blower to enhance ground
water recovery and to remove soil vapors in the vicinity of the recovery wells. The treated
ground water is pumped to three recharge wells located hydraulically upgradient of the
contamination source area.
The remediation system was started on June 20, 1995. Although the system has been
operational since startup, periodic shutdown of the remediation system due to high water levels
in the recharge wells has been impeding efforts to remediate this site. ATC/ATEC Associates
Inc. (ATC) is submitting this NPDES permit application on behalf of Circle K for permission to
discharge under the NPDES General Permit, instead of the current disposal scenario at the site.
The NPDES Notice of Intent form is included in Appendix A. Figure 1 represents a site
topographic map showing the intermittent stream discharge location. Figure 2 represents a
site vicinity map showing the proximity of the stream to the treatment system.
1.2 Site Background
_ The Circle K Store #8379 (site), located at 101 Mount Holly Road in Belmont, North
Carolina, consists of a convenience store, three underground storage tanks, and a gasoline
dispensing system. Figure 3 represents a site map of the Circle K site. In December 1992, one
of the three underground storage tanks, containing unleaded gasoline, was suspected of
1

i
r leaking. The Mooresville Regional Office of the North Carolina Division of Environmental
Management (NCDEM) was notified. An initial investigation was conducted by Delta
Environmental Consultants, Inc. (Delta) in early 1993. In June 1993, free product was
discovered in monitoring well GW03, and preliminary corrective action (manual bailing) was
r-, implemented. A Comprehensive Site Assessment (CSA) was completed by Delta in October
i_ 1993. During investigation activities, petroleum hydrocarbons were detected in the soil and
ground water samples collected at the site.
In February 1994, on -site UST closure activities were conducted by Jones and Frank, and
monitored by ATEC Associates, Inc. (ATEC). The majority of impacted soil was removed
during the tank excavation. - ATEC was retained by Circle K to complete a Corrective Action
Plan (CAP). The CAP, which proposed vacuum enhanced ground water extraction and
treatment, was submitted to the NCDEM in May 1994. Discharge of the treated ground water
to three recharge wells was proposed. A Non -Discharge Permit was issued for this facility in
November 1994 (Permit No. WQ0009615). ATEC initiated implementation of the CAP in
January 1995 by preparing plans, specifications, and bid documents.
1.3 Objectives of Corrective Action
There are two primary objectives of corrective action at the subject facility. The primary
objective is to protect the water supply well located at Belmont Abbey College from impact
related to the gasoline release located at the Circle K site. The water supply well at Belmont
Abbey College supplies potable water to the staff and students of the college, approximately
-- 1,500 people. Figure 2 indicates the proximity of the water supply well to the Circle K site,
which is approximately 600 feet. The other primary objective of corrective action at the site is
to restore soil and ground water to conditions which will not present a risk to human health
and the environment.
2

1.4 System Construction
In late April 1995, ATEC initiated site work for the installation of the ground water
remediation system. The recovery system consists of vacuum enhanced recovery using four
recovery wells with pneumatic, top loading pumps. The ground water treatment system
i
(GWTS) consists of an oil/water separator and associated free product storage tank, air
stripping using a low profile stripper, prefiltration using bag filters, and a carbon polishing unit.
The soil vapor extraction system (SVE) consists of a moisture separator, particulate filter, and
a regenerative blower. The SVE system extracts soil vapors in the vicinity of the recovery
wells and enhances ground water recovery.
On June 20, 1995, the ground water remediation system was started without carbon polishing.
System influent and effluent samples were collected, and the system was then shut down. On
June 27, 1995, a carbon polishing unit was installed and the system was restarted.
From June 27, 1995, until February 27, 1996, the ground water recovery system only utilized
recovery well RWO1 (GW11). Because free product was limited to the immediate vicinity of
recovery well RWO1, the system continued to pump only from RWO1, minimizing the risk of
free product migration away from RWO1. The remaining recovery wells, RW02 (GW12),
RW03 (GW 13), and RW04 (GW 14), were placed into operation on February 27, 1996.

2.0 GROUNDWATER CHARACTERIZATION
2.1 Free Product Recovery
Manual free product recovery at recovery well RWO1 (GWl1) was initiated on May 19, 1995,
and continued on a weekly basis through June 20, 1995. , Since system startup (June 20, 1995),
free product from RWO1 (MW-11) has been continuously- recovered into an oil/water
separator using a pneumatic submersible pump. This top loading pump's intake valve is set at
40 feet below top of casing (TOC). Approximately 70 gallons of free product have been
collected in the product recovery tank since startup. Free product has not been detected in any
of the remaining recovery or monitoring wells.
2.2 Ground Water Levels
Ground water levels fluctuate seasonally in monitoring wells GWO1, (!V105, GW09, GW 10,
and GW 15 through GW 19. The depth to ground water from TOC across the site varies from
approximately 24 to 35 feet below land surface (bls). Figure 4 represents a ground water
elevation contour map for the recent semiannual sampling event, performed on January 6,
1997. The . measurements represent ground water levels under pumping conditions. An
oil/water interface probe was used to measure the depths to ground water from the TOC, and
to check for free product in each well. Ground water elevations were then calculated based on
TOC elevations, which are referenced to an arbitrary benchmark of 100.00. Based on the
ground water elevation data for all of the gauging events, ground water flow direction is
generally to the south.
El

2.3 Ground Water Quality
_ On January 6, 1997, ground water samples were collected from monitoring wells GWO1,
I GW05 GW09 GW 10 GW,15 GW 16 GW 17 GW 18 and GW 19 for chemical analyses.
Prior to sampling, a minimum of three well volumes of ground water were bailed from each
well. A dedicated, disposable bailer was used to obtain each water sample. The samples were
then placed in an appropriate container, properly labeled, and preserved on ice. All samples
were transported under chain of custody to ATC Laboratories in Atlanta, Georgia. The
monitoring well samples were analyzed for BTEX (benzene, toluene ethylbenzene, and
xylenes) and MTBE (methyl -tertiary -butyl ether) using EPA Method 602. The laboratory
analytical report for ground water quality is included in Appendix B. An isoconcentration map
representing the extent of total BTEX contamination is included as Figure S. In addition, the
historical analytical results for each sampling event are summarized in Table 1. The next
semiannual sampling event will occur in July 1997.
According to the NPDES Notice of Intent form, additional analytical monitoring data must be
obtained to sufficiently characterize the type and concentration of contaminants on site. In
addition to total BTEX constituents and MTBE, the following parameters must be reported:
Lead, naphthalene, total phenols, 1,2-Dichlorethane, fluorene, and phenanthrene. On May 7,
1997, ATC personnel sampled the influent and effluent of the GWTS for the specified
parameters. The laboratory analytical results for the sampling event are included in Appendix
B. Based on the analytical results, the influent samples contained detectable concentrations of
benzene, toluene, ethylbenzene, total xylenes, MTBE, isopropyl ether (IPE), 1,2-
Dichloroethane, and lead. The only specified parameters detected in the effluent were total
xylenes and MTBE. The carbon treatment units were replaced on May 19, 1997; therefore,
the results of the June influent/effluent sampling event will not indicate total xylenes and MTBE
in the effluent. Table 2 summarizes the analytical results for the May 7, 1997, influent and
effluent sampling event.

3.0 GROUND WATER TREATMENT SYSTEM DISCHARGE OPTIONS
Four disposal options exist for the treated effluent at the site. These options include:
• Sanitary sewer disposal (POTW);
• Infiltration gallery / Injection wells;
• Spray Irrigation; and
• NPDES General Permit Discharge
3.1 Sanitary Sewer Disposal (POTW)
Since the connection to the nearest sewer line is located 400 feet away from the site, effluent
disposal into the sanitary sewer would require extensive construction and multiple off site
access agreements. The subject site utilizes a septic tank for sewer disposal. In addition to the
challenging logistics for connection to the POTW, other disadvantages include POTW usage
fees, and monthly monitoring and reporting requirements.
3.2 Infiltration Gallery / Injection Wells
Treated ground water effluent is currently discharged to three recharge wells located along the
upgradient boundary of the site under Non -Discharge Permit No. WQ0009615. Since the site
has been undergoing ground water remediation, the GWTS has automatically shut down
_ eighteen times due to the activation of a high water level switch in the recharge wells. Based
on the system downtime summary in Table 3, the frequency of system shutdowns due to high
water levels in the recharge wells represents approximately 80 percent of the shutdown
i
occurrences. Despite repeated adjustments to minimize the quantity of effluent per batch
processed, the recharge wells are not functioning to the degree necessary to achieve site
- remediation goals. At the current time, the recovery well pumps have been raised to reduce
ground water yield and subsequently the amount of effluent discharged to the recharge wells.
3

space hydraulically upgradient of the contamination source area, additional recharge wells
cannot be installed. Furthermore, the tight nature of the soils and the percolation test results
(May 16, 1994) provide evidence that an infiltration gallery is not feasible.
3.3 Spray Irrigation
Since the Circle K property is used for a convenience store and does not provide enough
available acreage, spray irrigation is not considered to be a feasible alternative for this site.
3.4 NPDES General Permit Discharge
Disposal of treated effluent to an unnamed intermittent stream located approximately 200 feet
from the site is a feasible and effective alternative to injection wells. The adjacent right-of-way
is operated by Plantation Pipe Line Company and they have provided preliminary approval to
cross their pipeline. A utility locator service will be notified regarding the AT&T fiber optic
line right-of-way. The current treatment system has all the components necessary to comply
with the NPDES General Permit treatment requirements, including an oil/water separator, low
profile air stripper, pretreatment filters, granular activated carbon polishing units, and an
effluent transfer pump. Figure 1 represents a topographic map which shows the location of
the stream. The stream extends north to Fites Creek, which travels east and discharges into the
Catawba River. Figure 6 shows the proposed discharge route for the GWTS effluent. As
indicated in Figure 6, the stream is approximately 6.5 feet downgradient of the treatment
system. The existing effluent transfer pump will be used to pump the treated effluent to the
stream. Appendix C includes headloss calculations for the proposed piping layout.
7

4.0 SOIL AND GROUND WATER REM EDIATION SYSTEM
4.1 Ground Water Treatment System
The GWTS was started on June 20, 1995. Through May 7, 1997, the GWTS has discharged
approximately 468,300 gallons of treated ground water to the recharge wells. Table 4
summarizes the GWTS removal efficiencies for benzene, total BTEX, and NiTBE. Appendix
D includes specifications for each of the GWTS components.
Ground water is first extracted from four recovery wells through the use of four top loading
valve pneumatic ejector pumps manufactured by Clean Environment Equipment (CEE).
Figure 7 represents the construction details for the recovery wells. A compressed air supply is
maintained by a Kellogg American CompAir compressor package which includes an. air
compressor delivering 17 cubic feet per minute (CFM) of air flow at 175 pounds per square
inch (PSI). The air compressor is powered by a 5 horsepower (HP) motor. During operation,
the top loading pump is filled with ground water from a check valve located at the top of the
pump. When the pump is full of fluid, a pneumatic valve is shifted and the fluid in the pump is
pressurized out of the pump by the compressed air. Once the fluid has discharged from the
pump, the pneumatic valve shifts to exhaust the compressed air and allow the pump to fill with
fluid for the next cycle. The pumping rate from each of the foul- recovery wells is rated at
5 gallons per minute (GPM). Figure 8 shows the current trenching layout at the site.
The GWTS is located at the rear of the Circle K building. (see Figure 8). The GWTS
components are housed in a weather proof shed set on a concrete pad. Figures 9 and 10
represent the GWTS piping and instrumentation layout. The ground water is first pumped
from the recovery wells to a 105-gallon oil/water separator manufactured by Hydro -Flo
(Model DP-4). The oil/water separator is rated at 12 GPM and is connected to a 55-gallon
free product recovery tank with a high level switch. The ground water is then gravity fed from

_ the oil/water separator to a holding tank located inside the system housing shed. The holding
jtank (transfer tank #1) is approximately 70 gallons and utilizes three water level switches to
control the transfer pump which pumps the water from the transfer tank to the air stripper.
When the water level in the transfer tank reaches the high level sensor, the transfer pump is
activated. Once the water level reaches the low level sensor, the transfer pump is deactivated.
If the water level reaches the high -high level sensor, the entire GWTS is shut down. Transfer
pump #1 is manufactured by Myers (Model 100 MT). At 10 GPM, the pump delivers 29.5
PSI (68 feet of water) and is powered by a'/z HP motor.
The water from the first transfer tank is pumped to a Geopure Ultrastrip Model 30 low profile
air stripper. The air stripper is rated at 10 GPM and contains four trays, as well as a 45-gallon
sump tank. The air/water ratio is rated 112:1. The air stripper blower is manufactured by
Rotron (Model R606884C) and is powered by a 3 HP motor. Once the volatile organic
contaminants (VOCs) have been removed from the influent, the effluent is gravity fed from the
sump tank to the next holding tank (transfer tank #2). The VOC-laden exhaust air is
discharged to the atmosphere through a cylindrical stack located on top of the air stripper.
Transfer tank #2 is approximately 275 gallons and utilizes the same water level switch
arrangement as transfer tank #1. In addition, transfer tank #2 controls a Myers 100 MT '/2 HP
pump (transfer pump #2). The water from transfer tank #2 is pumped through two 50-micron
bag filters in parallel (Ametek Model PBH420). Each filter is rated for 50 GPM at 90 PSI.
Following the filters, the water is pumped through two granular activated carbon vessels in
series (Geopure Model 1HPL95). Each vessel is rated for 10 GPM at 75 PSI and contains 95
pounds of virgin carbon. Following carbon treatment, the water is pumped to three recharge
wells located hydraulically upgradient of the contamination source area. Figure 11 represents
the construction details for the recharge wells.
9

4.2 Soil Vapor Extraction System
The soil vapor extraction (SVE) system is located to the west of the GWTS (see Figure 2).
The SVE system consists of a moisture separator, an Hine particulate filter, and a regenerative
blower manufactured by Roots (Model URAI-33). The blower operates at 120 CFM and
10" of Mercury (Hg). Soil vapors in the vicinity of the recovery wells are extracted by the
SVE system and discharged to the atmosphere through a vertical stack located after the
blower. When the water level in the moisture separator reaches the high level sensor, the high
level switch shuts off the ground water and SVE systems.
4.3 Proposed NPDES Discharge Plan
The proposed NPDES discharge plan will include discharge of the treated GWTS effluent to
the intermittent stream, as shown in Figures 1 and 6. The treated effluent will be pumped by
transfer pump #2 through a 2-inch schedule 40 PVC pipe to the receiving stream. As indicated
in Figure 6, the stream is approximately 200 feet from the treatment system. The stream is
also 6.5 feet downgradient of the treatment system. According to the headloss calculations in
Appendix C, transfer pump #2 will be capable of overcoming the total headloss due to friction
and fittings. Figure 12 represents the proposed changes to the GWTS effluent discharge.
5.0 SUMMARY
Circle K is currently operating a soil and ground water remediation system installed for
corrective action at the Circle K Store #8379 in Belmont, North Carolina. Treated ground
water from the GWTS is pumped to three recharge wells located hydraulically upgradient of
the contamination source area. Due to the compact silty -clay in the vicinity of the recharge
wells, the GWTS effluent cannot readily recharge through the recharge wells into the
10

unconfined aquifer. Therefore, the high water level switch in recharge wells RC -I, RC-2, or
RC-3 deactivates the GWTS.
The frequent system shutdowns (up to 80 percent of operation time) caused by high water
levels in the recharge wells prevent the GWTS from achieving the primary objectives of
corrective action. One of the objectives includes the protection of the water supply well at
Belmont Abbey College. In addition, the GWTS was installed to restore soil and ground water
conditions which will not present a risk to human health and the environment. Based on the
contaminant isoconcentration maps, the GWTS is not recovering contaminated ground water
at an optimum rate to achieve site remediation goals. Therefore, direct discharge under a
- NPDES General Permit would allow the GWTS to operate full time, and consequently,
achieve the primary objectives of the corrective action. The Groundwater Section of the
NCDEHNR Mooresville Regional Office has also reconunended direct discharge as a feasible
alternative for effective ground water recovery.

6. Alternatives to Direct Discharge:
Address. the feasibility of implementing each of the following non -discharge altematives:
a.. Connection to a Regional Sewer Collection System - If the facility is existing and currently
discharges to a POTW, when will connection not be allowed?
b. Subsurface disposal (including nitrification field, infiltration gallery, injection wells, etc.)
c. Spray irrigation
The alternatives to discharge analysis should include boring logs and/or other information indicating
that a subsurface system is neither feasible nor practical as well as written evidence indicating that
connection to a POTW is not an option. It should also include a present value of costs analysis as
outlined in the Divisions Guidance For Evaluation of Wastewater Disposal Alternatives.
7. Additional Application Requirements:
For new or proposed discharges, the following information must be included in triplicate with this

efficiencies for parameters of concern. The specifications must be signed and sealed, by a North
Carolina registered Professional Engineer and shall include a narrative description of the
treatment system to be constructed.
c. USGS topographic map (or photocopied portion thereof) with discharge location clearly
indicated. If the discharge is not directly to a stream, the pathway to the receiving stream must be
clearly indicated. This includes tracing the pathway of a storm sewer to its discharge point.
d. Analytical monitoring data which sufficiently characterizes the type and concentration of
contaminants on site. This includes a listing of any chemicals found with the maximum observed
concentrations reported. The data provided must be no older than one year prior to the date of this
application. At a minimum, the following parameters must be reported: Benzene, Toluene,

4 HEAD LOSS DUE TO FRICTION Values of Specific Roughness for Commbn Pipe Materials
The original Bernoulli equation was based on an assump-
tion of frictionless flow. In actual practice, friction occurs
during fluid flow. This friction "robs" the fluid of energy,
so that the fluid at the end of a pipe section has less energy
than it does at the beginning a
Et > EZ 17.14
Most formulas for calculating friction loss use the symbol
h f to represent the head loss due to friction 5 This loss
is added into the original Bernoulli equation to restore the
equality. Of course, the units of h f must be the same as the
units for the other terms in the Bernoulli equation. If the
Bernoulli equation is written in terms of energy, the units
will be ft-lbf/lbm or J/kg.
El =E2+Ef 17.15
Consider the constant -diameter, horizontal pipe in Fig. 17.2.
An incompressible fluid is flowing at a steady rate. Since
the elevation of the pipe does not change,. the potential
energy is constant. Since the pipe has a constant area, the
kinetic energy (velocity) is constant. Therefore, the friction
energy loss must show up as a decrease in pressure energy.
Since the fluid is incompressible, this can only occur if the
pressure decreases in the direction of flow.

ROUGHNESS
Ii`is intuitive that pipes with rough inside surfaces will ex-
perience greater friction losses than smooth pipes.6 Specific
roughness, e, is a parameter that measures the average size
of imperfections inside the pipe. Table 17.1 lists values of
e for common pipe materials. (Also, see App. 17.A.)
However, an imperfection the size of a sand grain will have
much more effect in a small -diameter hydraulic line than in
a large -diameter sewer. Therefore, the relative roughness,
e/D, is used as a better indicator of pipe roughness. Both
e and D have units of length (e.g., feet or meters), and the
relative roughness is dimensionless.
°The friction generates minute .amounts of heat. The heat is lost to the
surroundings.
50ther names and symbols for this friction loss are friction head loss
(hL), lost work (LW), friction heating (F), skin friction loss (Ff), and
pressure drop due to friction (Op f). All terms and symbols mean basically
the same thing, although the units may need converting.
6Surprisingly, this intuitive statement is valid only for turbulent flow. The

FACTOR
Vie Darcy friction factor, f , is one of the parameters that
is used to calculate the friction loss. The friction factor is
not constant, but decreases as the Reynolds number (fluid
velocity) increases, up to a certain point, known as fully
turbulent flow (or rough -pipe flow). Once the flow is fully
turbulent, the friction factor remains constant and depends
only on the relative roughness and not the Reynolds num-
ber. For very smooth pipes, fully turbulent flow is achieved
only at very high Reynolds numbers.

Figure 17.3 Friction Factor as a Function of Reynolds
Number
The. friction factor is not dependent on the material of the
pipe but is affected by the roughness. For example, for a
given Reynolds number, the friction factor will be the same
for any smooth pipe material (e.g., glass, plastic, smooth
brass and copper, etc.).
The friction factor is determined from the relative rough-
ness, e/D, and the Reynolds number, Re, by various meth-
ods. These methods include explicit and implicit equations,
the Moody diagram, and tables. The values obtained are
based on experimentation, primarily the work of J. Niku-
radse in the early 1930s.
A. Friction Factors for Laminar Flow
The easiest method of obtaining the friction factor for lam-
inar flow (Re < 2100) is to calculate it. Equation 17.16,
known as the Darcy equation, illustrates that roughness is
There are actually two friction factors: the Darcy friction factor and
the Fanning friction factor, fFanning, also known as the skin friction
coefficient and mall shear stress factor. Both factors are -in widespread
use, sharing the same symbol, f. Civil and (most) mechanical engineets:�Z:
use the Darcy friction factor. The Fanning friction factor is encountered
more often in the chemical industry. -One can be derived from the other;:

R = hydraulic radius, m (ft)
S = slope of energy grade line, rn/m (ft/ft.)
This equation was developed originally in U.S. customary units and was writ-
ten
V = CR0•11S1.54(0.001)-0.04
Hazen and Williams stated that "the last term ... (was) introduced to equalize
the value of C with the value in ... other exponential formulas .. , at a slope
of 0.001 instead of at a slope of I - [ 161. The term (0.001)' 0.04, which appears as
the term 1.318 in Eq. 2-29a, is combined with unit conversion factors to yield
the constant 0.849 in Eq. 2-29.
If D14 is substituted for the hydraulic radius R. the Hazen -Williams equa-
tion written in terms of the f7owrate Q is
Q = 0.278 CD1.11So.54 (SI units) 2-30
Q = 0.432 CD1.13So.54 (U.S. customary units) (2-30a
where Q = flowrate, m3/s (ft3/s).
Typical C values are shown in Table 2-2.
Example 2-2 Use of the Hazen -Williams equation Determine the head loss in a 1000-m (3280-
ft) pipeline with a diameter of 500 mm (20 in) that is discharging 0.25 ni:Vs (8.8 ft"/s). Assume
that the Hazen -Williams coefficient for the pipe egmil, 130.
SOLUTION
I. Compute the head loss with the Hazen -Williams cyuation. Rearrange Eq. 2-30 to allow
calculation of head loss.

Comparison of the Darcy-Weisbach, Manning, and Hazen-Willial
Because the Darcy-Weisbach, Manning, and Hazen -Williams eqi:
used frequently in practice, it is important to know their similariti
ences. They can be compared more easily if each is solved for tht
energy grade line:

AutoPump Manual
INTRODUCTION
Clean Environment Equipment
Page 1
The AutoPump is a pneumatic ejector, which means that it pumps in doses or
shots. The indicated flow rate is therefore an average taken over a time period.
The obtained flow rate assumes that the compressed air supply will be
maintained to allow the pump to operate normally. The system is suitable for
handling any liquid which will flow rapidly into the pump and be compatible
with the component materials listed below and with the connecting plumbing
lines. The pump is intended for vertical operation only, in well casings having
an internal diameter greater than the outside diameter of the pump by 10% or
more.
The AutoPump is very versatile and available in a wide range of lengths and
valve arrangements. The most common arrangements are the top or bottom
loading valve arrangements on a regular length (48" long) pump. The
drawings of these arrangements are included in the back of this manual.
OPERATION SPECIFICATIONS
The following are conditions under which the pump will operate:
Well Head Air Supply: 5 to 140 PSI
Total Developed Head: 110 PSI
Input Head: 0-to 30 Feet
Maximum Flow Rate: Top Loading - 5 GPM
Bottom Loading - 7 GPM
If the user wishes to operate beyond these ranges, please call the factory for
guidance.

MODE OF OPERATION
The pump will discharge fluid as long as ' fluid can fill the pump and there is
sufficient air pressure to move the fluid out of the pump. When the pump is
full of fluid, a pneumatic -valve is shifted and the fluid in the pump is
pressurized out of the pump by compressed air. When the pump has emptied
itself, the pneumatic valve shifts to exhaust the compressed air and allow the
pump to again fill with fluid.
Bottom Loading - The pump fills from a check valve located at the bottom of
the pump. The fluid level in the well can be decreased to a point about 4/5 up
the pump casing.
Top Loading - The pump fills from a check valve located at the top of the
pump. Therefore the fluid level in the well will never go below .the level of
this check valve.

AuWPump Manual Clean. Environment Equipment Page 3
ADDITIONAL CONTROLS
The pump will operate with air which is somewhat oily and wet or with clean, .
dry air. Particles should be removed from the air stream. A filter/regulator
should be installed on the supply air line. The filter should be between 5 and
40 micron. The regulator should be able to produce at least as much pressure as
required to move the fluid from the depth at which the pump is installed.
HOSES
Air Supply - 3/8" I.D. hose (green) with a one-way shut off quick connect fitting.

_ Air Exhaust - 1/2" I.D. hose (blue) with a straight -through 1/2" quick connect
fitting.
Some drawings of the positioning of AutoPumps in wells are included with
j this narrative. The color of the hoses shown in the drawings may differ from
the hoses shipped with the pump. However, the fittings will not interchange,
so one cannot connect a hose to an incorrect fitting.
it
NOTE: The down well hose fittings have locking quick connects. In order to
retract the sliding sleeve on the socket to accept or release its mating plug, the
slot in the sleeve must be aligned with the ball in the body of the socket. After
connection, rotate the sleeve so it cannot slide back and release the plug.

Low tower height produces numerous
advantages:
Rapid installation
Easy winterization
Inconspicuous appearance
Easy shipping
Easy maintenance
The UltraStrip unit also reduces the
potential for fouling since it contains no
packing media and provides an extreme
turbulent condition.
GeoPure's UltraStrip units are available
with a number of plate configurations,
blowers and controls, and can achieve
removal efficiency up to 99.99%.
THE U LTRASTRI P
• Low Profile Air Stripper from GeoPure
GeoPure's UltraStrip series is the best choice
for low profile air strippers with design
simplicity, flexibility and high performance.
In GeoPure's units the water and air are
contacted in on multiple trays. The water enters
at the top and flows across each tray. The air
rises through openings in the trays, then bub-
bles through the water to form "a surface of
foam" which provides extreme turbulence and
volatilization. Since the water in the UltraStrip
flows horizontally across each tray, the required
removal efficiency can be achieved by increas-
ing both the number and size of the trays.
- Another advantage of UltraStrip units is that
air and blower power are effectively utilized
since a single air stream passes through every
tray before exiting: As.a result of minimal air
flows, the organic contaminants are concen-
trated and can be effectively removed by vapor
phase carbon or other off -gas treatments.

1. Before installing, verify that the materials of construction
of the AMETEK Bag Filter System are compatible with
the fluid being filtered.
Start-up
1. Open the inlet valve. It is recommended that the inlet
valve be opened before the outlet valve to prevent any
backflow from occuring.
2. Vent trapped air from the system before opening the
the outlet valve.
Warning: Review all precautions specific to the handling of
the fluid being filtered before changing the filter bag. A filter
bag that has been used with a hazardous liquid may contain
residual amounts of this material and should -be ..handled
with the same safeguards that would be used in handling
any hazardous and/or toxic material i.e. gloves, respirators,
protective eyewear, etc. Filter bags should be disposed of
in accordance with federal, state or local laws and
requirements. Failure to follow precautions may result in
injury.
3. Open the outlet valve.
2. The location of the filter should include the following
considerations: adequate space for ease of changing
the filter bag, drainage or containment to collect drained Bag Selection
or spilled liquid, and proper ventilation, if required.
3. The installation should include isolation valves for the
filter and support for the filter housing. Caution should
be. used in applying heat near the filter housing. It is
best to weld or sweat all fittings before assembly to the
filter. The filter head may be mounted to the filter support
using 5/16" X 1-1/4" lag bolts. The bolt spacing is X on -
center and the bolt circle is 2-1/8".
4.. The filter must be installed in the vertical position with
the inlet/outlet ports at the top. Flow through the housing
is in -line. Note the inlet and outlet ports when connecting
piping.
5. The filter housing is. equipped with a 1/4" NPT gauge
port on the outlet for installation of a pressure gauge
(included) and a 3/8" NPT drain port at the base of the
sump (3/8" NPT ball valve supplied). The gauge or valve
should be installed using teflon tape as a thread sealant.
Is
The AMETEK Bag Filter Housing is designed for use with
AMETEK filter bags. However, the housing may accept some
filter bags from other manufacturers. The unit is designed
to accept a standard 4" FILTER SPECIALISTS, INC. (FSI)
POLYLOC filter bag. .
Other 4" filter bags may work if they. meet the following
criteria:
1. Filter bag length equals the depth of the filter basket
plus one inch.
2. The maximum allowable thickness of the filter bag at
the sealing surface is .080 inches.
3. The minimum allowable thickness of the filter bag at
the sealing surface is .040 inches.
Note: TheAMETEK bag filter housing may not be compatible
with filter bags using reinforcing rings or snap bands.

Bag Replacement
The pressure differential across the bag will remain fairly
constant until the bag is approximately 80% blinded off. It is
recommended that the bag be changed when the pressure
differential reaches 15 psi. However, this figure can vary
with the type of filter bag. The bag manufacturers data should
be consulted to determine the actual pressure drop for
replacement.
i
See Warning under Start -Up
1. Close isolation valves to the filter.
- 4.
5.
6.
Drain sump. (See Warning above) Note: If bag has not
been changed on a timely basis it may not drain. If
necessary, the liquid contents of the used bag can be
poured into the replacement bag to be filtered.
Unscrew sump from cap. Sump will unscrew counter-
clockwise.
Caution: Support sump at base while unscrewing to
prevent dropping and possibly damaging the sump or
drain valve.
Remove basket assembly from sump. (See Warning
above)
Remove bag from basket.
Remove O-ring from groove in the sump and wipe
groove and O-ring clean. Relubricate O-ring and place
back in groove. Make sure the O-ring is seated level in
the groove.
j 7. Insert new bag into the basket. Form the bag to the
- contours of the basket, making sure that the bag extends
fully to the bottom of the basket. Note: Make sure the
filter bag overlaps the bag collar to insure a proper seal
- when the filter housing is closed.
8. Screw the sump onto the cap and hand tighten securely.
Do not over -tighten.
Troubleshooting
Leaks
1. Check the O-ring for dirt, cuts, or swelling. If visible,
replace O-ring.
2. Make sure housing is closed properly. Hand tighten
securely. Do not over -tighten.
3. Check all threaded connections and redo as needed.
4. Check to see if the filter bag is dirty and blinded off.
(See Warning above) If this is the case, replace bag
according to instructions.
Poor Filtration Results
1. Check to make sure the filter bag is properly seated in
the support basket. (See Warning above) The bag
should extend fully to the bottom of the basket and the
top should overlap the sealing collar.
2. Check for rips -or tears in -the filter bag.

DRUMS AND VESSELS
FOR CARBON ADSORPTION
Remediation of organic compounds requires a higher
grade of carbon for effective adsorption of VOC molecules.
GeoPure' virgin -grade liquid phase GAC is graded with a
minimum iodine number of 950.
The iodine number represents the number of sites in
the carbon granule that.are available for adsorption. The
greater the iodine number, the greater the carbon's capac-
ity for adsorption.
Using a virgin carbon with greater capacity can
improve the effectiveness and economics for the remedia-
tion and control of organic compounds.
GeoPure also offers a complete line of manifolding
and prefiltration systems. These field proven systems opti-
mize your carbon use.
A quantity discount schedule is available for your con-
venience. Enquire with a GeoPure technical representative
for available discounts, specials and incentives.
