Dear Mr. Vickey:
NPDES Permit No. LAOO42731 River Bend Station - Unit 1 On January 27,1992, Gulf States Utilities Company submitted a permit application with Louisiana Department of Environmental Quality to renew our Louisiana Water Discharge Permit No. WPO409. That submittal was similar to our 1990 NPDES submittal to your agency, describing modifications planned for the station's heat dissipation system and to the sanitary waste treatment system, but not yet implemented. Both applications presumed the arrival of the zebra mussel in our area of the Mississippi River during the term of the permits, and included the treatment of makeup water with sodium hypochlorite/ sodium bromide when the zebra mussels did anive. On June 17, 1993, as part of the state permit application, GSU submitted to LDEO the Environmental impact Ouestionnaire required by Louisiana application procedures, and notified both EPA and LDEQ in that submittal that the modifications described in the permit application had been completed. At that time, GSU also notified both agencies that the fresh water mollusk, Dreissena polymorpha (zebra mussel), was positively identified in the station river makeup water GSU's intention at that time was to inject a continuous low level of sodium hypochlorite/ sodium bromide into the river water intake to control infestation by the zebra mussel, since that option was already covered in the existing NPDES Permit LAOO42731. However, GSU continues to review afternatives to oxidant injection for zebra mussel control, and we believe that a non-oxidizing biocide, specifically, a quaterr<ary amine, can be used to .j j \\ o 0l 9312080069 931109 e i PDR ADOCK 05000458 P PDR n f I n
Page 2 of 3 Lett'er to Mr. Bob Vickery November 9,1993 RBG-39,342 RBEXEC-93-650 i t r effectively protect 75e station makeup water system from significant operational impacts from l zebra mussels. l I GSU and Calgon Corporation have performed testing of one of these quaternary amine compound on samples of our intake water. This test consisted of adding this H-130M product to intake water samples at concentrations ranging from 1 to 7 ppm, and verifying that upon i settling, this compound is removed from the water by combining with sediment particles (or L bentonite, if needed) and settling out of the water. The supernatant water (i.e., clarifier l effluent, to be supplied to the cooling towers) from these samples was tested for H-130M l residual. All samples of supernate indicated no detectable residual (at or above 10 ppb) of the quaternary amine in comparison to the control sample (0 ppm H-130M), or from water treated i with 1 ppm,5 ppm and 7 ppm of the H-130M product. This test also verified that there is l ? already sufficient clay in our intake water to sequester and remove residual product before the i water is transferred to the cooling tower system. i GSU plans to use the Calgon product H-130M, EPA Registration No. 6836-203, a solution of quaternary alkyl ammonium compound (didecyl-dimethylammonium chloride), only three or four days per year between the months of May and November. This treatment strategy calls for addition of the H-130M tc the river water intake to achieve a concentration of approximately 5 parts per million for up to 24 hours on only those three or four days. The intention of this treatment is to eliminate any zebra mussels which may settle out and survive in the unprotected portions of the intake water pipeline between the river and the cladfiers. By providing a one-day treatment with H-130M approximately every 2 months during the spawning season, the settled survivors would be eliminated before reaching a level of maturity i sufficient for spawning themselves. Therefore, please find enclosed NFDES Permit Application Form 2C, item 11B, Attachments 1 and 2, which have been updated to reflect the proposed use of quaternary amine for zebra i mussel control. Included also are Calgon's Product Environmental Data Sheet and Material Safety Data Sheet. GSU requests that our permit be modified as necessary to provide for our use of this amended chemical water treatment to protect our station makeup water system. Also, we have positively identified year-old adult zebra mussels adhering to the interior surfaces of the 2.6 mile buried pipeline for river water makeup to the clarifiers. We wish to proceed with a one-day treatment before the end of 1993, using Calgen H 130M to protect the intake pipeline. t GSU met with representatives of LDEO Water Pollution Control Division's Permits Section on October 13,1993, to brief them on the vulnerability of our plant to zebra musselinfestation and to present our proposed treatment with Calgon H-130M and to discuss any concerns they l might have conceming the toxicity and efficacy issues relating to this treatment. GSU requested permission from Louisiana Department of Environmental Quality to proceed with this - one-day treatment before the end of 1993, while our Louisiana Water Discharge Permit WPO409 is being finalized. We anticipate this permission in the form of a Letter of No Objection allowing us to proceed with this one-day treatment if our permit is not ready before the end of 1993. GSU would be glad to meet with your agency to discuss any aspects of our proposed usage of this quaternary amine product. Should you require further information. contact Mr. Michael Harrington at (504) 381-4780. l t ?
