Agency dated October 15, 2007, or as subsequently amended.
The Division understands that you have made no significant changes to your facility the last permit
renewal. We have trade the following updates to your previous permit:
• added updates to facility map, outfall locations and parameter cedes
• added Monthly Average Lit -nit of 30.0 mg/L forTotal Suspended Solids (TSS)
• for Oil & Grease, please mate that [00556] remains the same for submitting DMR/eDMR, but use
test EPA method 1664 (SGT- ryM) with results in mg/L
• replaced Phenol (single compound) [346 4] with Total Recoverable Phenolics [32730].
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
specify that, if a state does not establish a system to receive such submittals, then penniftees must submit
DMRs electronically to the Environmental Protection Agency (EPA), The Division anticipates that these
regulations will be adopted and is beginning implementation.
The requirement to begin reporting discharge monitoring data: electronically using the NC DWR,'s

A. (3.)` FLOW MEASUREMENT RATIONAL [G.S. 143- 15.1 b)]
The Rational Equation: =KUC'IA., where:
Q = flow (Peak flow rate (efs or tm3/sec)
Ku = units conversation factor =1.00 for U.S. standard units (usually
ignored because it is so close to 1), or 0.278 for SI units
C = dimensionless runoff coefficient for the watershed, loosely defined
as the ratio of runoff to rainfall
1= intensity of rainfall taken from the intensity -duration -frequency
curves for the specified design return period at the time of
concentration, tc (in/h or mm/l). tc = time of concentration (tine
after the beginning of rainfall excess when all portions of the
drainage basin are contributing simultaneously to flow at the
outlet).
A = area of tributary watershed (acres or km2)
The rational equation is used to calculate the runoff from a region, given.:
• the runoff coefficient which accounts for infiltration and other
potentiallosses in the region,
the rainfall intensity to the region,
* the time it takes for runoff to travel from the re ion's upper reaches
to its outlet, and the region's drainage area.

Qualifier Meaning
T8 (ESC) - Additional method/sample information: Sample(s) received past/toe
close to holding time expiration.
Qualifier Report Information
ESC utilizes sample and result qualifiers as set forth by the EPA. Contract Laboratory Program and
as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted
by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical
results. Each qualifier is designated in the qualifier explanation as either EPA or ESC.
Data qualifiers are intended to provide the ESC client with more detailed information concerning
the potential bias of .reported data.. Because of the wide range of constituents and variety of
matrices incorporated by most EPA methods,it is common for some compounds to fall outside of
established ranges. These exceptions are evaluated and all reported data is valid and useable
unless qualified as 'R' (Rejected).
Definitions
Accuracy - The relationship of the observed value of a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix spike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate v organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC Tentatively identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.

Dear Mr. Eaton:
Our records indicate that NPDES Permit No. NCO021962 was issued on May 1, 2006 for
the discharge of wastewater to the surface waters of the State from your facility. The purpose of
this "'letter is to advise you of the importance of the Permit and the liabilities in the event of failure.
to comply with the terms and conditions of the Permit. If you have not already done so, it is
suggested that you thoroughly read. the Permit. Of particular! importance are Pages 4 and 5.
Pages 4 and 5 set forth the effluent limitations ` d monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth. The section headed
"Monitoring Requirements" describes the measurement frequencies, sample types and sampling
locations. Uponcommencement of your discharge (or operation), you must initiate the required
monitoring. The monitoring results must be entered on reporting forms furnished or approved b
this Agency. For new permits/facilities, the Division may supply an initial small stock of these
forms; however, if you fail to receive the forms, please contact this Office as quickly as possible.
The forms, including directions for their completion, and other important information are also

conditions include special reporting requirements in the event of noncompliance, bypasses,
treatment unit/process failures, etc. Also addressed are requirements for a certified wastewater
treatment plant operator if you are operating wastewater treatment facilities. Any changes in
operation of wastewater treatment facilities, quantity and type of wastewater being treated or
discharged, expansions and/or upgrading of wastewater treatment facilities must be permitted or
approved by this Agency.
To maintain compliance with discharge limitations, proper operation and maintenance of
a wastewater treatment facility and the development of a process control program are essential.
For those facilities having chlorine tablet disinfection, please be advised that chlorine tablets
approved for wastewater treatment use must be used; swimming pool tablets are not approved.
Also, be advised that DWQ staff need to have access to the facility's discharge point into the
receiving stream; please maintain a path along the outfall line to facilitate that access.
Failure to comply with the terms and conditions of an NPDES Permit subjects the
Permittee to enforcement action pursuant to Section 143-215.6 of the North Carolina General
Statutes, A civil penalty of up to $25,000 per violation (and/or criminal penalties)'may be
assessed for such violations. If you find at any time that you are unable to comply with the terms
and conditions of the Permit, you should contact this Office immediately. A Special Order by
Consent (SOC) may be necessary while pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a five-year period. Permits are
not automatically renewed. Renewal requests must be submitted to this Agency no later than 180
days prior to expiration, Please make note of the expiration date of your Pennit. This date is set
forth on Page I of the Permit. Also note that NPDES Permits are not automatically transferable.
If you, as the Permittee, cease to need this Permit, then you should request that the Division of
Water Quality rescind the Permit or request that DWQ reissue the Permit to another party, if
necessary.
As mentioned previously, the purpose of this letter is to advise you of the importance of
your NPDES Permit, Please read the Permit and contact this Office at 704/663-1699 in
Mooresville if you have any questions or need clarification. We look forward to providing any
assistance.

Dear Mr. Eaton.
The Division of Water Quality (the Division) hereby issues the attached NPDES permit for the
subject facility.This permit is issued pursuant to the requirements of North Carolina General
Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Enviromnental Protection Agency dated May 9, 1994, or as subsequently amended.
RENEWAL SUMMARY
The Division's renewal evaluation included a reasonable potential analysis ( A), in
accordance with EPA permitting guidance. Based on data from your Discharge Monitoring
Report (T s) submitted over the last permit cycle, the Division made the following
changes to your previous permit:
• Toluene — deleted permit limit; continue monthly monitoring
• Naphthalene — added monthly monitoring.
Total Suspended Solids -- Changes to the Draft Permit. The Division inadvertently
changed your previous permit limit for Total Suspended Solids (TSS) from 45 m to 30
mg/L. This has been corrected for the final permit to 45 .
Removed Benzene Limit. At your request of April 20, 2006, the Division reconsidered the
database for benzene. Ignoring the benzene hit of 1.5 laglL in March 2003, the Division finds
that benzene has not been detect at your site since that date (through February 2006). We have
therefore removed the benzene limit from the final permit. However, monthly monitoring is
still required.

that you thoroughly read the Permit. Of particular importance are Pages 4 ands.
Pages 4 and 5 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth. The section headed
"Monitoring Requirements" describes the measurement frequencies, sample types and sampling
locations. Upon commencement of your discharge (car operation), you must initiate the rewired.
monitoring. The monitoring results must be entered on reporting forms furnished or approved by this
Agency. If you have not received these forms, they should be arriving shortly. If you fail to receive
the forms, please contact this Office as quickly as possible. I have enclosed a sample of the "Effluent"
reporting form (DWQ Form -1), plus instructions for completing the farm. It is imperative that
all applicable parts be completed, and the original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be required

Subject Issuance of XlMerrnit NCO02196
Paw Creek Terminal

Dear Mr. Eaton:
Division of Water Quality personnel have reviewed and approved your application for renewal of the subject permit.'
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-2151 and the Memorandum of Agreement between North Carolina and the U.S. Environmental
Protection Agency dated May 9,1994 (or as subsequently amended). Please note the following changes from your draft permit, most
of which arc the result of the Paw Creek hearing officer's recommendations:
• pH monitoring and limits have been removed from your permit. This was an error made in all of the Paw Creek
draft permits. The ;pH requirement was eliminated in the previous permitting cycle and should not have been included in
the 2001 permits.
The MTBE limit of 11.6 ltg/I.. has been removed from the permit. As per the hearing officer's recommendations, a
peer -reviewed criterion for 'N E-does not exist and willnot be included as partof the permitting strategy for the Paw
Creek permits. It is anticipated that a criterion will be in place when this permit is next renewed. In addition to
monthly monitoring of MTBE, please see Part A.(3.) for some additional requirements related to MTBE.
• The monthly monitoring requirement for naphthalene has been deleted. Semi-annual monitoring using EPA
Method 625 replaces it.' As per the hearing officer's report, 625 is the best method for detecting naphthalene and other
middle distillate compounds and is therefore a more appropriate monitoring requirement. If your facility collects eight to
ten samples in which none of the 625 compounds are detected, you may submit request to the Division that this
sampling requirement beeliminated.
• Flow monitoring frequency has been changed from monthly to episodic. As per a request by the Mooresville
Regional Office, flow must be measured with each discharge event.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to, you, you have
the right to an adjudicatory hearing upon: written request within (30) days following receipt of this letter. This request must be in
the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filcd with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision
shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require modification or
revocations and reissuance of the permit. This permit dries not affect the legal requirements to obtain other permits which may be
required by the Division of Water Quality or permits required by the Division of Land Resources, the Coastal Area Management Act
or any other Federal or Local governmental permit that may be required.
If you have any questions concerning this permit, please contact Natalie Sierra at telephone number [phone],
extension 551.
Sincerely,

- Act, as amended,
a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during a calendar month on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month. It is therefore, an arithmetic mean found by
adding the weights of the pollutant found each day of the month and then dividing this sum by the number
of days the tests were reported. The Imitation is identified as "Monthly Average" in Part I of the permit,
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided
by the number of daily discharges sampled and/or measured during such week. It is, therefore, an arithmetic
mean found by adding the weights of pollutants found each day of the week and then dividing this sum by
the number of days the tests were reported. This limitation is identified as "Weekly Average" in Part I of the
permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If
only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum
daily discharge." This Imitation is identified as "Daily Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar year on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding
the weights of pollutants found each day of the year and then dividing this sum by the number of days the
tests were reported. This limitation is defined as "Annual Average" in Part I of the permit.
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar month on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured during such
month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a calendar month. This Imitation
is identified as "Monthly Average" under "Other Limits" in Part'I of the permit.

June, July through September, and October through December.
7. QLh—eK Measurementa
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is
determined as the arithmetic mean of the total daily flows recorded during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the
sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually
without interruption throughout the operating hours of the facility. Flow shall be monitored continually
except for the infrequent times when there may be no flow or for infrequent maintenance activities on the
flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(I) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and
combined proportional to the rate of flow measured at the time of individual sample collection, or

Part 11
Page 3 of 11
S. a. (2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between
samples determined by'a preset number of gallons passing the sampling point. Flow measurement
between sample intervals shall be determined by use of a flow recorder and totalizer, and the present
gallon interval between sample collection fixed at no greater than 1/24 of ithe expected total daily flow at
the treatment system, or
(3) a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
effluent grab samples may be collected at time intervals evenly spaced over the 24-hour period which are
equal in number of hours to the detention time of the system in number of days. However, in no case
may, the time interval between effluent grab samples be greater than six (6) hours nor the number of
samples less than four (4) during a 24-hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not exceeding 15 minutes;
the grab sample can be taken manually. Grab samples must be representative of the discharge or the
receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided
by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual
values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog
of the arithmetic mean of the logarithms of the individual values. For purposes of calculating the geometric
mean, values of zero (0) shall be considered to be one &
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its
respective flow divided by the summation of the respective flows.
10. Calendar Da). A calendar day is defined as the period from midnight of one day until midnight of the next day.
However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day
may be used for sampling.
11. Hazardous Substance: A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant: A toxic pollutant is any pollutant listed as toxic under Section 307(a)(l) of the Clean
Water Act.

a. Definitions
"Bypass" means the known diversion of waste streams from any portion of a treatment facility including
the collection system, which is not a designed or established or operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to the treatment
facilities which causes them to become inoperable, or substantial and permanent loss of natural resources
which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not
mean economic loss caused by delays in production.

P
4. b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to be exi
only if it also is for essential maintenance to assure efficient operation. These bypasses are not su'
provisions of Paragraphs c. and d. of this section.
c. Notice
0) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall st

T--FFo—w— During periods of no flow, the\�perrnittte` shall submit a monthly Discharge Monitoring Report
(DMR) indicating "No discharge." Flow mq* monitored in one of four ways:
a) measure flow continuously;
b) calculate flow based on total rainfall per area draining to the outfall; exclude built -upon
area (best method for facilities with large runoff -collection ponds);
c) estimate flow at 20-minute intervals during the entire discharge event; or
d) report flow based on discharge pump logs.
2. Oil and Grease — Where possible, the grab sample for oil and grease should be skimmed from
the surface of a quiescent (calm water) zone.
3. Turbidity Effluent shall not cause receiving stream turbidity to exceed 50 NTU. If receiving stream
background turbidity exceeds 50 NTU, effluent shall not cause this background value to increase.
4. pH shall not fall below 6.0 nor exceed 9.0 standard units.
5. Acute Toxicity (Fathead Minnow, 24-hour), Annual [see Special Condition A.(2.)).
There shall be no discharge of floating solids or foam visible in other than trace amounts.
There shall be no direct discharge of tank solids, tank bottom water, or the rag layer.
There shall be no direct discharge of tank (or pipe) contents following hydrostatic testing unless benzene
concentration is less than 1.1 pg/l and toluene concentration is less than I I pg/l.

BACKGROUND
C;itgo Petroleum Corporation stores several million gallons of gasoline and diesel on the site of the
subject permit. Effluent water discharged from the outfall consists of stormwater from the secondary
containment areas (around the individual tanks), runoff from the loading :rack, and discharge water following
hydrostatic testing. Water from the loading rack goes through an oil water ;separator and there goes to a
containment basin where it combines with the stormwater. The water is released manually as need through
outfall 001
The cover letter to the permit renewal application indicated that Citgo is pursuing a non -discharge
(spray irrigation) option for discharge of the stormwater.

In addition to the NOVs mentioned above, the facility has received on e NOV for violations of th(
daily maximum limits for benzene (January and February 2000) and one for exceedence of the daily maximim
limit for TS (November 199).
DMR Review.

The twice- ual EPA. 624/625 se revealed non -detects For nearly all of the semi-volatiles and
volatiles tested. 'There was one detect of methylene chloride (6 ug/1, -- just above the detection level of 5
ug/L), this has been identified as a potential laboratory contaminant by Savannah Laboratories.
Since March 1999, the facility has been required to sample for turbidity quarterly as per IPA
directive. They haves pled durir Y each discharge event since the requirement was instilled — the average
turbidity value in the past year d a Elf is 7.79 NTU with a maximum turbidity value of 22 NTU
e facility has passed its acute toxicity test since 1997.
Reasonable PotentialAnalysis ( A):
Reasonable potential was performed for benzene, toluene, turbidity, xylene and phenol. The analysis
indicated that effluent from this facility shows reasonable potential to violate water quality standards for
benzene, toluene and turbidity. liven that the facility has received NOVs for benzene, toluene and TSS
(which is related to turbidity), it is somewhat erected that this would be the case. RPA predicted a maxims
xylee concentration of 6.7 ug/L, this is below the water quality based allowable concentration. of 88.5 pug/L.
The allowable phenol concentration is based upon a 2/23/01 memo by Joe Corporon of the NPDES Unit that
specifies a 0.43 lbs./clay phenol loading for each terminal discharging to WS waters in the Paw Greer area.
The allowable concentration at this facility is 84 ug/L; RPA predicted a maximum concentration of 229.4
ug/L.
Allowable Phenol Concentration Calculation for 001:
0.43lbs l day I = 0.83 /
8.34 0.062'GL)
PERMITTING STRATEGY
The permitting strategy for this and all oil terminals in the state is based upon a 201 NPDES
document entitled, "Permit Requirements for Discharges from Oil d Petroleum Storage Facilities." This
document is based upon a 1996 SOP and has been updated by the NPDES Unit after a data review and internal
discussions. It delineates monitoring frequencies and permitting limits for contaminants commonly found at
these sites. This document is heretofore referred to as the "2001 SOP."
Waste Load Allocation (WLA).
The last waste load allocation was performed in 1994. Concerns were expressed over excessive
turbidity, benzene and toluene in the effluent. It recommends limits for benzene, toluene and TSS and
monthly monitoring for BTEX, lead, phenol and MT13E.

Foornotes:
I Where no measurable discharge occurs, "no discharge" should be, clearly noted on the submitted monthly discharge monitoring report.
Flow may be monitored in one of four ways: a) Measure flow continuously, b) Calculate flow based on the area draining to the outfall, the built upon
area, and the total rainfall (this method of flow measurement should not be used at facilities that have large ponds to collect
surface water runoff), c) Estimate by flow measurement at 20 minute intervals during the entire discharge event, or d) Base flow on pump logs.
2 Where possible, the grab sample for oil and grease should be skimmed from the surface of a quiescent (calm water) zone.
3 EPA Method 625 includes five (5) chlorophenols. If one or more chlorophenol(s) is detected at concentrations greater than or equal to 50 tig/l, the
permittee will be required to analyze for the eight chlorophenols (listed below) in addition to EPA Method 625. This additional required monitoring
will begin with the permittee's next scheduled monitoring event, occur on a semi-annual basis, and will last for the duration of the permit. Eight
chlorophenols include the following: 3-chlorophenol, 4-chlorophenol, 2,3-dichlorophenol, 2,5-dichlorophenol, 2,6--dichlorophenol, 3,4-
dichlorophenol, 2,3,4,6-Tetrachlorophenol, and 3-methyl-6-chlorophenol.
4 Acute Toxicity (Fathead Minnow, 24-hour) Monitoring, Episodic, See Part III, Condition E.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
There shall be no direct discharge of tank solids, tank bottom water, or the rag layer.
There shall be no direct discharge of tank contents following hydrostatic testing unless the benzene concentration is less than 1.19 ug/I and the toluene

I Where no measurable discharge occurs, "no discharge" should be clearly noted on the submitted monthly discharge monitoring report.
Flow maybe monitored in one of four ways: a) Measure flow continuously, b) Calculate flow based on the area draining to the outfall, the built upon
area, and the total rainfall (this method of flow measurement should not be used at facilities that have large ponds to collect
surface water runoff), c) Estimate by flow measurement at 20 minute intervals during the entire discharge event, or d) Base flow on pump logs.
2 Where possible, the grab sample for oil and grease should be skimmed from the surface of a quiescent (calm water) zone.

PART
IV — EVALUATION AND RECOMMENDATIONS
The permittee, Citgo Petroleum Corporation, has applied for
permit
renewal. The existing facilities appeared to be well
maintained
and operated; however, the oil/water separator may not
be adequate
to protect the receiving stream. The addition of the
new
WWT facilities should provide adequate treatment to protect
water quality standards.

Page four
The benzene and toluene effluent limits are requested since
the facility has discharged effluent with reported valuesfor these
constituent higher than stream standards. Since' the facility
discharges into a zero flow stream, it is likely that water quality
stream standards were violated.
This Office recommends at this time that the bulk storage
facilities not be covered under the General Permit for groundwater
remediation. The groundwater remediatian outfall should be
included in the subject` permit and given appropriate effluent
limits, including toxicity testing.
The proposed WWT' facilities which are in the review process
have: already been constructed, however, they are not in use'.
Inspection of these facilities indicates a pump station after the
existing oil/water separator which is not shown on the plans
submitted for review. The pump station also has 'a bypass line
which should be plugged.
It is recommended that the permit be;renewed once the 'above
mentioned concerns are addressed.

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Spi Instructions Dr nL— n --CD- =--a
All volumes of wastewater leaving the facility must be monitored. If continuous monitoring is not feasible, then the
discharger shall record the approximate times that discharge began and ended, along with the instantaneous flow at the
time of effluent sampling. Analysis for Benzene, Toluene, and Xylene should be accomplished using an EPA approved
method to a detection level of at least 1 ppb. Also recommend monitoring for methyl tert-butyl ether (MTBE) and Ethyl
benzene should be accomplished using an EPA approved method. This monitoring should be performed at the same time
that the whole effluent toxicity test sample is taken annually. A reopener clause should be placed in the permit to allow
limits to he placed on toxicants should the facility fail its whole effluent toxicity test.
Explain exact pathway of discharge i.e. storm sewer to tributary, etc.)

separator to treat stormwater runoff prig to discharge. The
upgrade includes the addition of an Ejector Systems Stripperator
after the existing Bail/water segar°ator. The Stripperator will
reduce the volatile organics in the for water to aid in meeting
NPDES permit restrictions This letter is to serve as notification
of the upgrade. The installation should be completed the week of
August 16, 1993. At this time •is not known if this unit will
require permitting for the off -gas emissions or if it will fall
under the bulb terminal operations exemption.-` letter to this
effect has been forwarded to Mecklenburg County DEP for their
response. The aerator will not be operated until it is properly
permitted.
Should you have any questions concerning this letter or need
further information, do not hesitate to call.
Sincerely,

Pilot Study Exemption
Citgo Petroleum Terminal
7600 Mt. Holly Road, Charlotte, NC
Dear Mr. Klemm: >.
e Mecklenburg County Department of Environmental Protection (" CDEP") has; reviewed
your request dated September 3, 1993 for conducting a Stripe or pilot study at Citgo Petroleum
Terminal at 7600 Mt. Holly Road, Charlotte, NC. A review of the submitted data reveals the
proposed activity is not likely to contravene any applicable ambient air quality or emission
control standard, and therefore, air quality pepnitting for this pilotstudy will not be required.
However, the following conditions and limitations must be met.
1 The stripe 'tor pilot study may be conductedfor a total of forty (40) hours during a three
(3) month period. MCDEP believes that'a sufficient number of rain events will occur
during this `amount of time to allow data 'collection.
2. The exhaust off the striperator must be run through control equipment, such as carbon
adsorption bcda.
. The estimated; volatile compound emissions shall be submitted to MCDEP within fifteen
(15) days of the pilot study completion.
4. This approval may be withdrawn should discharges from the source cause injury,
detriment, nuisance or damage to business or property.
5. Notify MCDEP at least three days prior to the actual pilot study.
.,,
If there are any questions regarding this muter, please call me at 336-5500.

Other petroleum company officials have contended that, while the discharges from
most of their marketing and bulk terminals are capable of meeting this "daily
maximum" limitation as stated above, certain of their facilities cannot be so
equipped to meet this limitation as stated above. If the permittee can present
sufficient evidence to demonstrate that this facility cannot be so equipped, the
State will modify this limitation to the extent needed (in no case to exceed
100,0 mg/1) to assure reasonable compliance with the "daily maximum" limitation.
It is recognized that influent quality changes, equipment malfunction, or other
circumstances may sometimes result in effluent concentrations exceeding the
permit limitations despite the exercise of appropriate care and maintenance
measures, and corrective measures by the permittee. The permittee may come
forward to demonstrate to the State that such circumstances exist in any case
where effluent concentrations exceed those set forth in this permit. The State
will consider such Information in determining appropriate enforcement measures,
if any, to be taken.
A calendar day is defined as any consecutive 24 hour period.
The "daily maximum" concentration is defined as the arithmetic average of one or
more representative grab samples taken during any calendar day. should effluent
sampling be done on more than one calendar day during the month, the arithmetic
average indicating the largest "daily maximum" concentration shall be reported
on the Discharge Monitoring Report Form.
Collection of representative samples shall be required during periods of
discharges. Should there be no discharge during normal working bours, the
permittee shall report "no discharge" for that reporting period.
The reported flow shall be the arithmetic average of the total volume discharged
on each of the sampling days during the reporting period. Flow may be
calculated utilizing a flow recorder, rain gauge, or any other similar device.
In connection with submission of records and reports required under this permit,
the permittee, shall not be deemed to have waived such privilege against
self-incrimination as may be offered under or by the Fifth Amendment of the
United States' Constitution.
