Acute toxicity4
Beginning on the effective date of the permit and lasting until expiration, the permittee is authorized to
discharge from Outfall 001. Such discharges shall be limited and monitored by the permittee as
specified below:
Footnotes:
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.
b.
measure flow continuously;
Rational Method — calculate flow based on total rainfall per area including built-on area
draining to the outfall (This method shall not be used at sites with large runoff-collection
ponds);
estimate flow at 20-minute intervals during the entire discharge event; or
report flow based on discharge pump logs.
Oil and Grease - Where possible, the grab sample for oil and grease should be skimmed from the surface of a quiescent
(calm water) zone.
MTBE - See section A. (2.) Effluent Limitations and Monitoring Requirements Special Conditions - MTBE
Monitoring for other requirements relating to MTBE.
Acute Toxicity - Annual, Fathead Minnow, 24-hour. See section A. (3.) Effluent Limitations and Monitoring
Requirements Special Conditions - Acute Toxicity Monitoring.

1. Quarterly monitoring for MTBE is required for the duration of the permit. See Part A. (1.).
A. (2.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL
CONDITIONS - 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:
2. 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 NC0027006
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.
A. (3.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL
CONDITIONS - 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:
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.
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.

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.
