Subject: NPDES Permit Issuance
Permit No. NCO022187
Star Enterprise - Paw Creek
Mecklenburg County
Dear Mr. Mayo:
In accordance with the application for a discharge permit received March 7, 1996, the Division is
forwarding herewith the subject state - NPDES permit. This permit is issued pursuant to the requirements
of North Carolina General Statute 143-215.land the Memorandum of Agreement between North Carolina
and the US Environmental Protection Agency dated December 6, 1983.
This final permit has been prepared after a careful review of the comments received. Your letter
dated May 8, 1996, had comments pertaining to the acute toxicity requirements, the employment of an
ORC, and a compliance schedule. Self monitoring toxicity results for January 1993 show that Star did
not pass their toxicity test and therefore, do not qualify for annual toxicity monitoring. Star is not required
to employ a certified wastewater treatment plant operator in responsible charge (ORC) as stipulated in Part
II Section C. Lastly, the Division has granted a 6 month compliance schedule .so that Star will have
sufficient time to submit a request for an Authorization to Construct (ATC) to meet these new limits. As
you may be aware, an ATC should be submitted at least 90 days prior to the start of any construction
activities.
In response to oil terminals' comments pertaining to the chlorophenol monitoring requirements in
the draft permits, the Division held a teleconference with representatives from the oil terminals and their
laboratories. The oil terminals' representatives had the following concerns: (1) Why was there a
requirement to monitor for eight individual chlorophenols in addition to those specified in EPA Method
625; and (2) What is the proper laboratory procedure to analyze for these eight chlorophenols?
After some additional data review, research, and discussion, two determinations were made.
First, although all chlorophenols have the potential to cause taste and odor problems in drinking water
supplies and tainting of fish tissue, the eight chlorophenols not covered by EPA Method 625 are not
considered to be carcinogens. Second, certain chlorophenolic compounds are likely to form first. This is
significant because certain parameters can be used to "screen" the stormwater discharge for the presence of
chlorophenols. Specifically, the five chlorophenols included in EPA Method 625 can be used as
indicators of all chlorophenols because these five compounds would be the first to form when chlorine
reacts with phenol.

Therefore, EPA Method 625 will be used as an initial screen. If no chlorophenols are detected, no
additional monitoring will be required. However, if one or more chlorophenols are detected at
concentrations greater than 50 µg/l, then the oil terminal would be required to monitor for the eight
additional chlorophenols beginning with the next scheduled monitoring event and continue to monitor until
the permit expired. The additional chlorophenol monitoring would include identifying and quantifying all
chlorophenols present in the sample(s).
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 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 demand is
made, this decision shall be final and binding.
Please take notice this permit is not transferable. Part 11, E.4. addresses the requirements to be
followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirements to obtain other permits which may be required
by the Division of Environmental Management or permits required by the Division of Land Resources,
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 Mr. Steve Pellei at telephone
number [phone], extension 516.

Part III Permit No. NCO022187 `
E. 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 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.
Raleigh, N.C. 27607
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.
Failure to submit suitable test results will constitute noncompliance with monitoring requirements.

PART IV - EVALUATION AND -RECOMMENDATIONS
The wastewater from the Star Enterprise sales terminal is
treated by an oil/water separator, an oil storage tank, and a
settling pond prior to discharge into an unnamed tributary,to Gum
Branch. From the oil storage tank the -discharge travels
approximately 500 feet (on the ground) around the spill containment
area before entering the settling pond. The discharge from the
pond is controlled by an outfall control valve, and the amount of
discharge depends on rainfall. Storm water is also directed to the
pond via the storm water drainage system.
According to Mr. Kirkwood, Terminal Manager, the tank bottom
water is pumped and hauled in trucks every 5 to 6 months to
NPDES Permit Staff Report
Version 10/92
Page 4

Jacksonville, Florida for disposal at a company called Industrial
Wastewater Services. The wastewater facilities at the Star
Enterprise Terminal appeared to be well operated and maintained.
An Authorization to Construct was issued on March 4, 1994 for
the construction of a groundwater remediation system, on which
construction has been completed. During the site investigation, it
was noted that the bare areas were seeded, the haul road was
graveled, and the catch basins were rip -rapped and had a graveled
inlet. Those measures were provided per this office's suggestion
to reduce settleable matter in the pond.
It is recommended that the NPDES permit for this facility be
renewed pending review by the Groundwater section.
