A. (1) EFFLUENT LI ATIONS AND MONITORING REQUIREMENTS
Beginning on th of ec i e date of the permit and lasting until expiration, the Permittee is authorized to
discharge from Outfal 00 Such discharges shall be limited and monitored by the Permittee as
specified below.

Footnotes:
1. Flow — During periods of no flow, the Permittee shall submit a monthly Discharge Monitoring Report (DMR)
indicating "No discharge." Flow shall be monitored with each discharge event 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; (this method of flow
measurement should not be used 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. 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.
3. Oil and Grease — Where possible, the grab sample for oil and grease should be skimmed from the
surface of a quiescent(calm water) zone. /

shall be collected concurrent with BTEX sampling.
There s aT a eb no cftscharge 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 1.19 µgll and toluene concentration is less than 1 I µg/l.

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2) ACUTE TOXICITY MONITORING (ANNUAL)
The Permittee 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
F,nvironrnental 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 NC0005185
A. (3) MTBE SP CIAL CONDITION
For the protection of ublic health, oil terminals that discharge to waters classified as water supplies
("WS" waters) will ad re to the following action plan:
1. As stated in Part (1) and (2), monthly monitoring of MTBE for the duration of the permit is
required.
2. After one year of man ly monitoring or once twelve data points have been collected, the
Permittee shall review t MTBE data collected. If MTBE has not been detected in any samples
taken during the first year, e facility may request that the monitoring frequency for MTBE be
reduced. This should be don by requesting the NPDES Unit to perform a minor modification to
the NPDES permit. In the case . which MTBE has been detected within the first year of
effluent sampling, the subject fac' ity must submit an MTBE reduction plan. This action plan
may include site-specific BMPs or gineering solutions. A copy of this plan should be
submitted to:
North Carolina ivision of Water Quality
Water uality Section
Attn: PDES Unit
1617 Mail ervice Center
Raleigh, N 27699-1617
3. By the time of the next permit renewal, it:is an 'cipated that surface water criterion for MTBE
will be established. This criterion will be used i conjunction with the facility's effluent MTBE
data to perform a reasonable potential analysis (R A). The RPA will determine whether effluent
from a facility has the potential to exceed a water ality standard or criterion, thereby requiring
a water quality limit in the NPDES permit.
