MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS Miscellaneous information pertinent to the renewal or new permit for this discharge. Include relationship to the Basinwide Management Plan. SPECIAL INSTRUCTIONS OR CONDITIONS Permit must contain flow monitoring requirement such that all volumes of wastewater leaving the facility are monitored. If continuous monitoring is not feasible, then discharger shall record the approximate times that discharge began and ended, along with instantaneous flow at the time of effluent samliing.tMonitoring for all toxicants should be performed during the first five discrete discharge events (monthly thereafter) after the effective date of the NPDES permit. Monitoring should occur at the same time that the whole -effluent toxicidy sample is collected during the discharge event (samples should be collected within 24 hours of the beginning of the event). WASTELOAD SENT TO EPA? (Major) (Y or N) (If yes, then attach schematic toxics spreadsheet, copy of model, or if not modeled, then old assumptions that were made, and description of how wasteload fits into basinwide plan.) Additional Information attached? (Y or N) If yes, explain with attachments. Facility Name Conoco- Charlotte Products Terminal _ Permit # NCO074705 _ Pipe # 001 ACUTE TOXICITY MONITORING (EPISODIC) The permittee shall conduct FIVE acute toxicity tests using protocols defined as definitive in E.P.A. Document 600/4-85/013 entitled "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, using effluent collected as a single grab sample. Effluent samples for self -monitoring purposes must be obtained below all waste treatment. Sampling and subsequent testing will occur during the fast five discrete discharge events after the effective date of this permit. After monitoring of the first five toxicity tests, the permittee will conduct one test annually, with the annual period beginning in January of the next calendar year. 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, DEM Form AT-1 (original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Environmental Management 4401 Reedy Creek Rd. Raleigh, N.C. 27607 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 Environmental Management 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. Failure to submit suitable test results will constitute noncompliance with monitoring requirements. 7Q10 0 cfs Permitted Flow NOL _ MGD IWC 100 % Basin & Sub -basin CTB34 Receiving Stream UT Paw Creel County Mecklenburg EAM Fathead 24 Version 10191 Re ommended by: Date 4/20P93 low 04 rX, A)46 P4. is 'flil f- -77 yrz/- �� J G `nn l l - J Till CHEM -BAC Z .'2�tc. • P.
