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; exclude built -upon
area (best method for facilities with large runoff -collection ponds);
b) estimate flow at 20-minute intervals during the entire discharge event; or
c) 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. MTBE — See Special Condition A.(2.) for other requirements relating to MTBE
4. Acute Toxicity (Fathead Minnow, 24-hour), Annual [see Special Condition A.(3.)].
Units: mg/L = milligrams per liter
jig/1 = micrograms per liter
lbs./day = pounds per day
MTBE = methyl tertiary butyl ether
The permittee shall not discharge floating solids or foam visible in other than trace amounts.
The permittee shall not discharge tank solids, tank bottom water, or the tank rag layer.
The permittee shall not discharge tank (or pipe) contents following hydrostatic testing unless benzene
concentration is less than 1.19 ug/L and toluene concentration is less than 11 ggIL.

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2.) MTBE MONITORING
For the protection of public health, oil terminals discharging to waters classified as water supplies
("WS" waters) shall adhere to the following action plan:
1. Monthly monitoring for MTBE (except as modified under 2.) is required for the duration
of the permit [See Part A. (L)].
2. After a one-year Test Period of monthly monitoring or after twelve (12) discharge events
have been sampled and analyzed, the Permittee shall review MTBE data. If MTBE is not
detected, the facility may request the Division to reduce the MTBE monitoring
frequency. Granting this request shall constitute a minor modification to the NPDES
permit.
3. If MTBE is detected during the Test Period, the Permittee shall submit an MTBE
Reduction Plan. This plan may include site -specific Best Management Practices (BMPs)
or engineering solutions. A copy of this plan shall be submitted to:
North Carolina Division of Water Quality
Water Quality Section
Attn: NPDES Unit
1617 Mail Service Center
Raleigh, NC 27699-1617
4. The Division anticipates that an MTBE regulatory criterion or Water Quality Standard
will be established during the coming permit cycle. For the next cycle of permit renewals,
the Division expects to apply this criterion .or standard to MTBE data collected during
this permit cycle. Should the permittee's MTBE data indicate discharge in excess of this
criterion or Water Quality Standard, an MTBE limit will be added to the permit
monitoring requirements at renewal.

Permit NCO003671
EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (3.) ACUTE TOXICITY MONITORING (ANNUAL)
The Permittee shall conduct annual toxicity tests using protocols defined as definitive in EPA Document
EPA/600/4-901027 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.
