The parameter code for Total Suspended Solids (TSS) should read C0530 - not C0556. We have therefore generated change -pages to correct this error. Please insert these pages into your existing permit and discard the old pages. We regret any inconvenience this may have caused your organization. This permit is not transferable except after notifying the Division of Water Resources. The Division may require permit modification, or revocation and re- issuance. Please note that this permit does not affect your legal obligation to obtain other permits required by the Division of Water Resources, the Division of Land Resources, the Coastal Area Management Act, or other federal or local governments.

(L) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS 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: EFFLUENT CHARACTERISTICS PARAMETER CODES LIMITS MONITORING RE UIREMENTS Monthly Average Daily Maximum Measurement Frequency Sample Type Sample Location Flowl 50050 Episodic 1 Effluent Total Suspended Solids C0530 45.0 mg/L Monthly Grab Effluent Oil & Grease 2 00556 Monthly Grab Effluent Total Recoverable Phenolics 32730 Monthly Grab Effluent Benzene 34030 Monthly Grab Effluent Toluene 34010 Monthly Grab Effluent Ethyl Benzene 34371 Monthly Grab .

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 [see section A. (3.)] Rational Equation) based on total rainfall per unit area draining to the outfall; exclude built -upon areas (best method 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. Oil and Grease — where possible, the grab sample should be skimmed from the surface of a quiescent (calm water) zone. 3. Acute Toxicity (Fathead Minnow, 24- hour), annually [see Special Condition A. (2.)]. Units: mg/L = milligrams per liter gg/L = micrograms per liter MTBE = methyl tertiary butyl ether Conditions: • The Permittee shall discharge no floating solids or foam. • The Permittee shall discharge no tank solids, tank bottom water, or tank rag layer. • The Permittee shall not discharge tank (or pipe) contents following hydrostatic testing unless benzene concentration is less than 1.19µg/1., and toluene concentration is less than 11 µg/L. N Permit NC0000795 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 Environmental Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699 -1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section 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. 21
