AAEA CODE 409 B38-6631 November 20, 1987 l RBG- 27029 File No. Gl.II.2 Mr. J. Dale Givens, Assistant Secretary Office of Water Resources Department of Environmental Quality Post Office Box 44091, Capitol Station Baton Rouge, LA 70804-4091

Dear Mr. Givens:

Water Discharge Permit No. 0409 NPDES Permit No. LA 0042731 River Bend Station - Unit 1 On the morning of November 17, 1987, analysis of a sample from Outfall 002, collected on November II, 1987 indicated an Oil and Grease (0&G) of 24 mg/1, which exceeded the permitted maximum O&G of 20 mg/1. The outfall 002 sample was from a 14,964 gallon batch release of low-volume waste.

At the time of collection, the visual appearance of the sample was normal and there was no indication of oil and grease. Investigation of possible causes of the elevated value has thus far failed to provide an explanation of the event.

This excursion resulted in the discharge of about 3 pounds of oil and grease to the Mississippi River. The relatively small amount of material, which was discharged via outfall 001 as a previously monitored effluent, probably had no measurable impact on the receiving stream.

Gulf States Utilities is continuing an investigation of the source of the excursion. Preventive measures will be implemented as more information becomes available.

I certify under penalty of law that this document and all attachments were prepared under the direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate and complete. I am aware that there are 8711300229 871120 8 DR ADOCK 050
