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.
Environmental Protection Agency dated May 9, 1994, or as subsequently amended.
MUA97_\ IF.YI)ti 147 /_\;h'/
The Division's renewal evaluation included a reasonable potential analysis (RPA), in
accordance with EPA permitting guidance. Based on data from your Discharge Monitoring
Report (DMRs) 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 mg/L to 30
mg/L. This has been corrected for the final permit to 45 mg/L.
Removed Benzene Limit. At your request of April 20, 2006, the Division reconsidered the
database for benzene. Ignoring the benzene hit of 1.5 µg/L 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.

Footnotes:
1. Flow — During periods of no flow, the Permittee shall submit a monthly Discharge Monitoring Report
(DMR) indicating "No discharge." Flow must be monitored with each discharge and may be
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. 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.
Following hydrostatic tank or pipe testing, the Permittee shall discharge no wastes containing
benzene concentrations greater than 1.19 µg/L, or toluene concentrations greater than 11 µg/L.

Permit NCO021962
EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2.) ACUTE TOXICITY MONITORING (ANNUAL)
The Pemrittee shall conduct annual toxicity tests using protocols defined as definitive in EPA Document
EPA/600/4-90/027 entitled "Methods for Measuring the Acute Toxicity of Effluents to Freshwater and
Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pimephales promelas)
24-hour static test. Effluent samples for self -monitoring purposes must be obtained below all waste
treatment. The permittee will conduct one test annually, with the annual period beginning in January of
the calendar year of the effective date of the permit. The annual test requirement must be performed and
reported by June 30. If no discharge occurs by June 30, notification will be made to the Division by this
date. Toxicity testing will be performed on the next discharge event for the annual test requirement.
The parameter code for this test is TAE6C. All toxicity testing results required as part of this permit
condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it was
performed, using the appropriate parameter code. Additionally, DWQ Form AT-1 (original) is to be sent
to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream.
Should any test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival and appropriate environmental controls, shall constitute an invalid test and will
require immediate follow-up testing to be completed no later than the last day of the month following the
month of the initial monitoring.

Permit NCO021962
A. (3.) MTBE MONITORING - SPECIAL CONDITION
For the protection of public health, oil terminals that discharge to waters classified as water supply
(WS waters) will adhere to the following action plan: As stated in Part A. (1), the Permittee shall
monitor MTBE monthly for the duration of this permit. If, after one year of monthly monitoring,
MTBE is not detected (or after twelve data points have been collected over a minimum six-month
period), the Permittee may request the Division to reduce the MTBE monitoring frequency. Such a
reduction shall be considered a minor permit modification.

Benzene. At the permittee's request (email of 20AprO6 from Scott Eaton), the Division
reconsidered the reasonable potential database for benzene. As drafted, reasonable
potential is based on only one hit of 1.5 µg/L in March 2003 (sample n =19 thru June
2005). Ignoring this single hit, benzene has not been detected in subsequent analyses
from April 2003 through February 2006.
Although monthly monitoring is mandatory and remains unchanged in the final permit,
the Division will remove the benzene limit based on the above database.

BACKGROUND
Citgo Petroleum Corporation stores several million gallons of gasoline and diesel within seven large surface tanks.
An earthen berm encircles these tanks as standard secondary -containment to prevent product loss in the event of a
tank rupture. Stormwater collecting within this bermed area must be discharged manually through Outfall 001.
This discharge may include stormwater runoff from a fuel -truck loading rack (via an oil water separator) and/or
maintenance wastewater generated during hydrostatic tank testing.
FILE REVIEW
Correspondence — Received Staff Report (Feb 28, 2005) from Samar Bou-Ghazale (MRO) recommending that
the Division renew this permit.
Compliance and DMR Review: DMRs were reviewed from January 2003 through December 2005. The
average discharge flow at 001 was 0.016 MGD with a maximum flow of 0.042 MGD in May 2003. Total
suspended solids (TSS) averaged 6.9 mg/L with a maximum 22 mg/L detected in 2002. The majority of the oil
and grease samples tested < 5 mg/L with one hit at 5.1 mg/L in November 2004.
The Permittee's annual Whole Effluent Toxicity (WET) Testing has been recorded as "pass" (LC 50 > 100) for
last 5 years.

PERMITTING STRATEGY
New SOP for Oil Terminals: The Division establish renewal criteria for this permit as documented in the NPDES
Permitting Requirements for Petroleum Bulk -Storage 2005 Permitting Strategy, version September 9, 2005 (2005
SOP). This document established 12 renewal criteria including a reasonable potential analyses (see Renewal
Summary). Database for this RPA is attached to this document.
Reasonable Potential Analysis (RPA): The Division conducted a reasonable potential analysis according to EPA
guidelines in order to establish potential for a given parameter to exceed its water -quality stream standard. The
Division established a list of parameters of concern (POCs) based on the previous permit. These parameters include
benzene, toluene, and turbidity. In addition, the Division evaluated the need for phenol limits appropriate for a
discharge to water supply (WS-IV) waters considering a total of eight bulk -storage petroleum discharges to this
watershed (see 2005 SOP, item 11).
Phenol Calculation. The phenol limits calculation considers phenol loading for all terminals discharging to WS
waters in the Paw Creek area. For this permit:
Outfall 001 Highest flow (recorded in May 2003) _
Therefore, loading for this outfall -
Outfa11001 = 0.48lbs./dav x 1
8.34 0.042 MGD
0.042 MGD
1.37 mg/L or 1,370 µg/L
Based on this calculation, 1,370 µg/L is the allowable concentration used to evaluate reasonable potential. Because
phenol was not detected (in 20 sample events) we conclude there is no reasonable potential to exceed the phenol
standard.
RENEWAL SUMMARY
• Phenol — (RP = No) retain monthly monitoring per 2005 SOP.
• Turbidity— (RP = Yes) retain permit limit of 50 NTU.
• Benzene — (RP = Yes) retain permit limit and monthly monitoring.
• Toluene — (RP = No) delete permit limit; continue monthly monitoring.
• Oil and Grease —Retain monthly monitoring per 2005 SOP.
• Naphthalene — add monthly monitoring per 2005 SOP (renewal application references diesel onsite).
Note: Database for the RPA is attached to this document.

To evaluate reasonable potential for phenol:
1) Use the facility's average wasteload/stormwater flow (highest monthly average flow
during the last permit cycle) to convert the calculated individual wasteload allocation
(per facility) of 0.481bs./day to a concentration in mg/L. v -O /f I
Single-Outfall Example: Highest flow for Outfall 001 = 0/ 3eMGD
001 = 0.48lbs./day x 1 =

MEMORANDUM
DATE: September 08, 2005
TO: NPDES Program
FROM: Joe R. Corporon, L.G.
Permit Writer
SUBJECT: Revised Guidance to Permit Writers — Allowable Phenol Loads for Bulk
Oil Terminals in the Paw Creek Area, Catawba River Basin.
As part of the newly revised Standard Operating Procedures — Permit Requirements for
Discharges from Oil and Petroleum Storage Facilities (SOP-2001), the Division has
recalculated the allowable load for phenol. New numbers are appropriate for bulk oil
distribution terminals discharging to an unnamed tributary of Gum Branch (WS-IV) and an
unnamed tributary of Long Creek (WS-IV CA), both within subbasin 030834. This document
affects eight (8) permitted facilities discharging to WS waters (see Table 1).
I have made these calculations considering the following background and assumptions:
1. The water quality stream standard comes from the EPA Document Ambient Water
Quality Criteria for Chlorinated Phenols. This standard has been included in the North
Carolina 2B .0200 Rules and has been applied to Water Supply (WS) waters since 1990.
2. The standard for chlorinated phenolic compounds is 1.0 pig/L. Although it is unlikely
that petroleum bulk storage facilities would discharge chlorinated phenolic compounds,
they may discharge phenol. Therefore, the Division is concerned that phenol (at levels of
1 µg/L or greater) has potential to create "daughter compounds" at downstream water
intakes where water is drawn from the river and chlorinated. It is therefore appropriate to
calculate allowable phenol load near the closest water intake downstream of these bulk
storage facilities.
3. I have applied the 30Q2 flow because the standard is based on potential aesthetic
concerns (taste and odor associated with chlorinated phenols in fish and drinking water).
I have applied the standard (1.0 µg/L) near the confluence of Long Creek and the
Catawba River (approximately 1,000 feet upstream) where the Division calculated 30Q2
flow at 716 cfs (based on Clariant Corporation's 1996 WLA, NC0004375). Therefore,
the allowable wasteload for each of nine (9) dischargers is calculated:
716 cfs x 0.001 mg/L x 8.34 = 3.85 lbs./day total phenol
1.55
3.851bs./day of phenol = 0.48 lbs./day per discharger
8 dischargers

Re: NPDES Permit #NC0021962
Dear Mr. Weaver,
I have enclosed the renewal form for the NPDES permit for the
CITGO Petroleum Bulk Storage Terminal in Charlotte.
The only change to the operation of the Terminal since the last
NPDES permit was issued is the addition of a stormwater spray
irrigation (non discharge) permit - permit #WQ0019911. Almost all of
the stormwater that accumulates in the dikes is released through the
spray irrigation permit.
The NPDES system at the terminal produces very little sludge.
The only sludge generated at the terminal is in the drain system to the
PCW tank and in the PCW tank. They are cleaned as needed and the
sludge is disposed through a qualified vendor, hauled off site, and
treated in compliance with applicable regulations.
Thank you for your attention in this matter. If there are any
questions, please call me at 770-458-8322.
Sincerely, ,yp�
