Hunt, Jr., Governor Jonathan B. Howes, Secretary UD E H N R A. Preston Howard, Jr., P.E., Director August 2, 1996 Ms. Barbara Castleberry Louis Dreyfus Energy 8800 Roswell Road, Suite 200 Atlanta, Georgia 30350 Subject: NPDES Permit Issuance Permit No. NC0021971 Southeast Terminal Mucklenb=rg Count, Dear Ms. Castleberry: In accordance with the application for a discharge permit received on December 6, 1995. the Division is forwarding herewith the subject NPDES permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated December 6, 1983. The Division acknowledges the May 17, 1996 letter requesting the removal of the USEPA Methods 624/625 monitoring requirement from NPDES permit no. NC0021971. However, the Division cannot grant the request. Extensive research, site visits, discussions with terminal operators and data review indicated that there is a lack of effluent data identifying the various constituents discharged from oil terminals. For the Division to identify constituents discharged in oil terminals' effluent that could potentially have an adverse impact on water quality, USEPA Methods 624/625 will be required on a semi-annual basis. It should be noted that upon permit renewal all data will be analyzed to identify potential adverse impacts to water quality. USEPA Methods 624/625 may not be required during subsequent permit periods if data support elimination of this requirement. In addition, the monitoring/outfall locations have been changed in the NPDES permit. The attached site plan of the Louis Dreyfus oil terminal indicates several outfalls only two of which are currently permitted by the NPDES permit (outfalls 001 and 002). The Division discussed this issue and developed three potential monitoring options for Louis Dreyfus. Each monitoring option should ensure that all stormwater discharged from the site is monitored. The three options are indicated on the site plan. Don Griffin (Louis Dreyfus) selected option no. 1 which consists of one sampling point located at the culvert under the railroad bridge south of tanks 108 and 109. Therefore, the Louis Dreyfus NPDES permit will only have one permitted outfall (rather than the two permitted outfalls in the existing permit). The final permit has been revised to include this change. Monitoring requirements from outfalls 001 and 002 will be combined into the new outfall which will be called outfall 009 so as not to confuse it with previous permitted outfalls. There have also been two changes to the permit on the Effluent Limitations and Monitoring Requirements page. Monthly monitoring with a 325.0 ug/I limit wfll be required for ethyl benzene and xylene monitoring will be required semi-annually. Benzene, toluene, and ethyl benzene were all detected in the effluent at concentrations that could potentially have adverse impacts on water quality. The ethyl benzene limit was inadvertently omitted from the draft permit. Several members of the public were concerned that the oil terminal discharge permits did not include xylene monitoring. Xylene is not included in USEPA Methods 624/625 and was recommended to be added by the hearing officer. Thus, the requirement has been added to all oil terminals discharging stormwater to surface waters. P.O.

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 contents following hydrostatic testing unless benzene concentration is less than 71.4 ug/1 and toluene concentration is less than 11 ug/l. Part III NPDES No. NCO021971 E. ACUTE TOXICITY MONITORING (ANNUAL) The permittee shall conduct annual toxicity tests using protocols defined as definitive 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, DEM Form AT-1 (original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Water Quality 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 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. Failure to submit suitable test results will constitute noncompliance with monitoring requirements.
