t 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.
Z Where possible, the grab sample for oil and grease should be sldmmed from the surface of a quiescent (calm water) zone.
3 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 benzene concentration is less than 1.19 ug/1 and toluene
concentration is less than 11 ug/l.

Part III Permit No. NC0031046
E. ACUTE TOXICITY MONITORING (ANNUAL)
The peanittee 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 testis 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: Environmental Sciences Branch
North Carolina Division of
Environmental Management
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 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.

testing waters.
PART IV - EVALUATION AND RECOMMENDATIONS
The company has indicated that they will be making every
effort to further reduce erosion and minimize turbidity
through the utilization of mini -wetlands and vegetative
buffers. These activities may occur within the next few
months and should not be considered as part of the NPDES
permit requirements at this time. Should these activities
improve water quality conditions at this facility, the
Division should consider possible incorporation of similar
buffers at other diked terminal facilities. WSRO recommends
that the permit be issued with standard conditions for oil
terminal operations. The Water Supply Section, the City of
High Point and Guilford County Environmental Health (Ken
Carter) should also be ven the opportunity to comment on
this permit renewparl. Z —_.�-,7

Postscript:
It may be advisable to have Mr. Miller provide a document
indicating that he has the authority to administer the
environmental program for the company. A review of the Region's
files did not produce such an authorization document. Who is the
