This was my fault. They came in during a cutoff period in late May/early June when I was pushing everyone hard to get as many permits as possible to notice. I made the decision to allow some folks to draft permits directly from the fact sheet and told them to put the fact sheet in Marcia's box after the draft was completed. I know this is not normal procedure but I felt it was necessary at the time. I gathered together the three fact sheets and placed them in Marcia's box today. I assure you I am NOT continuing this practice and I apologize for any confusion it caused.

Keasey Unocal Refining & Marketing Division Unocal Corporation PO Box 4147 Atlanta, Georgia 30302 Dear Mr. Keasey: MAR 2 7 1990 Subject: Modification to NPDES Permit No. NCO021971 Unocal Corporation -Charlotte Mecklenburg County I BRANCH The Division of Environmental Management is forwarding herewith a modification to the subject permit. This modification is to replace the 48-hour LC50 Ceriodaphnia toxicity requirement with a 24-hour LC50 Fathead Minnow toxicity requirement since this latter toxicity test is more appropriate for facilities of the subject type which have infrequent and relatively small discharges. A revised Part III, Condition G is attached and should be inserted into your NPDES permit. Please discard the old Part III, Condition G. All other terms and conditions contained in the original permit remain unchanged and in full effect. This modification 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. This permit modification becomes effective immediately. If this decision is unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer 11666, Raleigh, North Carolina, 27604. Unless such a demand is made, this decision shall be final and binding. Pollution Prevention Pays P.O.

ACUTE TOXICITY TESTING REQUIREMENT Fathead Minnow 24 hr - Monitoring (Annual) for Episodic Events The permittee shall conduct FIVE acute toxicity tests using protocols defined 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 first 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 P.O. Box 27687 Raleigh, N.C. 27611 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 reopened 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.

Si.C,q u 090' North Carolina Department of Environment, Health, and Natural Resources Division of Environmental Management 512 North Salisbury Street Raleigh, North Carolina 27611 Attn: Mr. Ken W. Eagleson Assistant Water Quality Section Chief REVISION OF BIOMONITORING REQUIREMENTS Southeast Terminal (Charlotte) NPDES No. NC0021971, Mecklenburg County Southeast Terminal (Greensboro) NPDES No. NC0026247, Guilford County I am writing to confirm that the biomonitoring requirements contained in the NPDES permits for the subject facilities are to modified. During a recent telephone conversation with your office I was informed that the current monitoring protocol, which specifies a 48-hour LC50 determination using Ceriodaphnia dubia as the test organism, is not now considered an appropriate test method. It was indicated that this test is now considered inappropriate for facilities which have only infrequent and relatively small discharges. The monitoring requirement that was considered to be more appropriate was cited as a 24- hour L.C50 test utilizing Fathead Minnows (Pimephales promelas) as the test species. It was indicated that we should proceed with the use of the new biomonitoring procedure for future testing, and that the NPDES permits for both of the facilities in question would be modified. Unocal is to change the biomonitoring program at the Greensboro and Charlotte Southeast Terminals. At each facility we will arrange to have five sequential discharges tested with the new procedure, and will continue with annual biomonitoring thereafter. I was advised during the telephone conversation that the NPDES permits for the subject facilities would be modified to show the changes described above, and that Unocal could proceed immediately to implement the changes. If there is any reason that we should wait to make the monitoring changes, please let me know as soon as possible. Unless we are advised otherwise, we will proceed with the new monitoring program. If you require additional information, please do not hesitate to call me at (404) 320-2272. Very truly yours, David R. Keasey Manager Marketing Environmental DRK/bmc cc: R. E. Van Deusen C. E.
