During the period 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:
1.
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 (or pipe) contents following hydrostatic testing unless benzene
concentration is less than 1.19 ng/1 and toluene concentration is less than 11 ng/l-
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 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
2. Where possible, the grab sample for oil and grease should be skimmed from the surface of a quiescent (calm
water) zone.
See Condition A. (2.)
EPA Method 625 includes 5 chlorophenols. If one or more of the chlorophenols is detected at concentrations
> 50 gg/1, the permittee will be required to analyze for the eight chlorophenols listed below in addition to EPA
Method 625. This additional monitoring will begin with the next scheduled sampling event and occur on a
semi-annual basis thereafter until expiration of the permit. The eight additional chlorophenols are:
• 3-chlorophenol
• 4-chlorophenol
• 2,3-dichlorophenol
• 2.5-dichlorophenol
• 2,6-dichlorophenol
• 3.4-dichlorophenol
• 2.3.4.6-tetrachlorophenol
• 3-methyl-6-chlorophenol
5. Acute Toxicity (Fathead Minnow, 24-hour), Annual (see Condition A. (3.).

A. (2). TOTAL NITROGEN MONITORING
(1) Monthly Loading (lb) = Days x TN x Qw x 8.34
TN
The annual mass loading is the sum of the monthly loadings:
(2) Annual Mass Loading (lb/year)= E (Monthly Loadings) for the calendar year
A. (3.) ACUTE TOXICITY MONITORING (Annual)
Attention:
The Permittee shall calculate annual total nitrogen mass loading as the sum of monthly loadings,
according to the following equations:
The Permittee shall report the total nitrogen concentration for each sample and the monthly mass
loading in the appropriate monthly self-monitoring report; the annual total nitrogen mass loading shall
be reported in the self-monitoring report for December of each year.
The permittee shall conduct annual toxicity tests using definitive protocols 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 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.
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.
