Subject: NPDES Permit Issuance
Permit No. NCO021954
CITGO Petroleum Corporation
Johnston County
In accordance with the application for a discharge permit received on October 6, 1997, the
Division is forwarding herewith the subject NPDES permit. 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 December 6, 1983,
and as subsequently amended.
In response to your letter of June 8, 1998, there has been a change to the final permit. The three
additional toxicity test results submitted by the facility complete a set of five consecutive passing
tests, and therefore the acute toxicity testing requirement foroutfall 001 has been changed from
episodic to annual testing only. This action is consistent with the Division's current standard
operating procedure for permitting petroleum storage facilities throughout the state.
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
thirty (30) days following receipt of this letter. This request must be made in the form of a written
petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611-
7447. Unless such a demand is made, this decision shall be final and binding.
Please take note that this permit is not transferable. Part II, E. 4. addresses the requirements to be
followed in case of change in ownership or control of this discharge.

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 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 µg/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.

SPECIAL CONDITIONS
A (3). ACUTE TOXICITY MONITORING (ANNUAL)
The permittee shall conduct annual toxicity.tests using protocols defined as definitive in E.P.A. 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: Environmental Sciences Branch
North Carolina Division of
Water Quality
4401 Reedy Creek Rd.

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.
A (4). ACUTE TOXICITY MONITORING (EPISODIC)
The permittee shall conduct FIVE acute toxicity tests using protocols defined as definitive in E.P.A.
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. Sampling and subsequent testing will occur during the first five discrete discharge events
after the effective date of this permit. After monitoring of the first five toxicity tests, the permittee will
conduct one test annually, with the annual period beginning in January of the next calendar year. 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

NOTES FOR CITGO PETROLEUM CORPORATION
PERMIT RENEWAL (NCO021594)
Wastewater discharge from CITGO Petroleum/Selma Terminal (Selma, Johnston County)
to unnamed tributary (UT) to Mill Creek in the Neuse River Basin.
15A NCAC 213.0300 Index # 27-40: Reclassified as WS-IV NSW 8/3/92.
Previous permit effective October 1, 1993; expires May 31, 1998.
WLA (214192) Information:
• Sub -Basin 03-04-02
• USGS Quad E25SE
• Receiving waters previously classified as C-NSW
• Average Flow = 0
• Summer/Winter 7Q10 = 0.0 cis
• 30Q2 = 0.0 cfs
• Recommends that Phenols be monitored during first five discharges, then annually
thereafter.
Limits Information:
Per 15A NCAC 2B .0216:
Benzene-1.19 µg/1 (for WS; non-WS is 71.4), Phenols-1.0 µg/1, Toluene-11 µg/l.
Per EPA Toxic Substance Spreadsheet:
Xylene-None, Ethylbenzene-3100 µg/l
DMR Review ('95-'97):
• Outfall 002 did not discharge in '96 or '97
• Phenols exceeded permitted limit in April and May-97 (67 and 16 µg/1, repectively);
DMRs say carbon beds were changed.
• Phenol Detection Limit (DL) noted by permitee as 10.0 µg/1
• TSS exceeded permitted limit in May 1997 (56.0 mg/1). DMR notes carbon beds
changed. NOV issued for this violation on July 28, 1997.
• Benzene, Toluene, Xylene, Ethylbenzene < 1.0 µg/l (May, 1996)
• Benzene reported as 25 µg/1 on 2/ 16/95
• Phenols exceeded permitted limit in January and February, 1995 (31 and 18 µg/l.
resp.)
• Phenols exceeded limit on several occasions in January, March, and May, 1994
• Oil and Grease (O&G) limit exceeded on 1 / 12/94 (47 mg/1)
Permit Information:
• Phenol DL specified to be 5.0 µg/l.
General Comments:
Why is CITGO using a method with only a 10.0 µg/l?
Cleared this up while on oil terminal site visits --will be monitoring for phenol only;
WQ standard is actually for chlorinated phenols. This was a previous inconsistency.
EPA methods 624/625 include chlorinated phenols and other contaminants of
interest.

NC0021954
blower, bag filter, dual carbon units, sump pump, etc. Staff Report dated 9/8/94
says that the proposed treatment system upgrade (above ATC) "should solve the
facility's compliance problems." From DMRs, compliance did appear to improve in
more recent years.
Paul Clark's Permit Requirements for Stormwater Discharges from Oil and Petroleum
Storage Facilities (SOP document) says quantitation levels for chlorophenols used by
the DWQ Chemistry Lab range from 10 to 50 jig/I. Laboratories should report their
data at the lowest quantitation level that provides reliable results.
The waste flow (Qw) used in the reasonable potential calculation was 0.034 MGD,
the maximum flow recorded on the DMRs in the past two years.
New expiration date to be assigned to this permit is March 31, 2003.
Acute Toxicity: 5 tests performed over previous permit period. 1/94-27.70/0, 2/94-
64.7%, 2/95-78.3%. Most recent tests, LC50>100%. Did the earlier tests constitute
a failure? Not specified in permit acute tox language, and no records of NOVs, etc.
issued for any acute tox violations.
Paul's handout says a facility which has not passed all five tox tests should be
required to monitor for acute tox during five storm events. Facilities that fall one or
more tests will be required to do quarterly monitoring for forthcoming permit period.
(I assume this would mean beginning in 2003.)
11/7/97 Staff Report by S. Mitchell recommends renewal, and cites no particular
problems.
4/ 14/92 Staff Report described treatment system as consisting of two oil/water
separators, one partially above ground for outfall 001, and one underground for 002.
1995 ATC replaced one of these (which one?). Called S. Mitchell 12/2/97 to clarify
what components make up current system and discharge to which outfalls.
Current System: one outfall inside the berm (001, probably) and one outside.
Facility currently treats all water inside berm (which mingles with stormwater) and
discharges --goes from striperaetor (sp?) to holding tank, then treated in o/w
separator. 002 is non -contact stormwater. Steve M. assumed underground o/w
separator has been removed.
12/8/97 discussion with Paul Clark --pH not usually a concern at these terminals.
Also, if turbidity limit exists in permit, perform reasonable potential calc. to
determine need to carry over. If not, leave out.
Reas. pot. calculation showed turbidity limit not necessary.
12/23/97 Spoke with Mike Lewandowski about treatment system. Said terminal
only uses treatment system for 001, but o/w separator still present for 002 as
backup. Do not normally discharge from 002 anymore.

Reference is made to the above mentioned Draft National Pollutant
Discharge Elimination System Permit. We have reviewed this permit
application and determined that the proposed discharge will not be
sufficiently close to any existing or known proposed public water supply
intake so as to create an adverse effect on water quality.
We concur with the issuance of this permit provided the facility is
operated and maintained properly, the stated effluent limits are met prior to
discharge, and the discharge does not contravene the designated water
quality standards.
If we can be of further assistance, please contact us.

Staff Review and Evaluation (cont.)
NPDES Wastewater Permit
NPDES Unit Comments:
• In an effort to more consistently permit oil and petroleum storage facilities, the NPDES Unit
reviewed available information and data and has implemented standard monitoring requirements
for these facilities. The Standard Operating Procedure (SOP) written by Paul Clark that outlines
these requirements, specific to Water -Supply and Non -Water -Supply dischargers, was used as the
guide to draft this permit.
• Not enough benzene data to perform reasonable potential; renewal does include benzene monthly
monitoring with no limit. ND (< 1.0 µg/1) reported in 1996, and 3/97 reported value was 7.4 µg/1;
WQ std. for WS waters is 1.19 µg/l. Region comment? Benzene will also be monitored semi-
annually via 624/625.
• No apparent compliance problems except for phenols (limited previously by a misinterpretation of
the WQ std.) Only chlorinated phenols is a concern for WS waters, and these compounds will be
screened by 624/625.
• CITGO's draft permit has already been noticed (before permit was intended to be included as part
of 030402 package) and was scheduled for issue at the end of March; however, it is being held to
coordinate its issue and any comments from Region with other permits in this sub -basin. Permittee
is aware of this, as well as the revisions to include Nutrient monitoring /Special Conditions.
Unless Region feels benzene could be a problem, it is recommended that the permit be renewed as
drafted.

Permit No. NCO021954
The permittee shall conduct an annual acute toxicity test using protocols defined as definitive in
E.P.A. Document 600/4-85/013 entitled "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, using effluent collected as a single grab sample. Effluent samples
for self -monitoring purposes must be obtained below all waste treatment. Sampling and
subsequent testing will occur during the first five discrete discharge events after the effective date
of this permit. After monitoring of the fast five toxicity tests, the permittee will conduct one test
annually, with the annual period beginning in January of the next calendar year. 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, DEM Form AT-1 (original) is
to be sent to the following address:
Attention:

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 Environmental Management 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.
Failure to submit suitable test results will constitute noncompliance with monitoring requirements.

DEAR MR. GOODRICH,
CITGO PETROLEUM CORP. OPERATES THE BULK STORAGE PETROLEUM
TERMINAL REFERENCED ABOVE, AND IS BY WAY OF THIS LETTER REQUESTING THE
RENEWAL OF NPDES PERMIT # NC0021954.
SLUDGE GENERATION AT THE FACILITY IS VERY MINIMAL. THE OIL / WATER

RESIDUES ARE DISPOSED OR RECLAIMED ACCORDING TO APPLICABLE
REGULATIONS.
IF I CAN BE OF ANY FURTHER HELP, PLEASE CALL ME AT 770-458-8322.
SINCERELY,
