Tech. Ccr. Lab. JUN 2 0 iGS3 To W. J. Weisenborn, Westlake, Louisiana From K. L. Kennedy, Ponca City, Oklahoma Oat* June 17, 1983 Subject Lake Charles Refinery Waste Water Treatment--ThepEffect of the Heavy Crude Project In my letter of November 12, 1982, the effects of the Heavy Crude project on the BOD and TSS levels of the final effluent were presented. Since that time, as you know, the water balance for this project has changed. You asked us to recalculate the effluent numbers. This letter contains the effluent numbers that were transmitted to you some time ago. It now appears that the refinery effluent after the Heavy Crude project will meet the Federal Best Available Technology Effluent Guidelines (BAT) without any changes in the refinery waste treatment system other than the planned addition of pretreatment flotation and storm water diversion. The new permit will be based on the 1982 BAT guidelines which are equivalent to the present effluent guidelines. Effluent values of ten pollutant parameters for the Heavy Crude project were calculated taking into account the effects of dissolved air flotation/ induced air flotation pretreatment and storm water diversion. These units may not be completed prior to the Heavy Crude startup but they will be required fairly quickly to prevent permit exceedances. In particular, the flotation units should be put into operation as soon as possible after the Heavy Crude startup. Table I shows the maximum 30-day average effluent values (95 percent probable numbers) predicted for the Heavy Crude project, the calculated permit values for the project and the maximum 30-day average value from eighteen months of actual operating data for each parameter. The current plant effluent values are much lower than the predicted values for the Heavy Crude project partly due to the fact that the refinery has been operating well below design capacity. The pollutant rates calculated for the Heavy Crude project are all equal to or below the BAT effluent guidelines values. The effluent value calculated for hexavalent chrome is equal to the permit value, however, the calcu lations reflect the fact that we do not know how higher levels of the metal will affect removal across the ASU. The value is necessarily conservative. The BOD, effluent value calculated for the Heavy Crude project is less than 10 percent below the BAT daily average effluent value. The activated sludge unit will have a relatively short residence time after the Heavy Crude project is started up (approximately 14 1/2 hours) and the unit could perform poorly due to hydraulic overloading. This is particularly true if feed to the treatment system from the storm water holding pond is not controlled properly. 000002327 MCD W. J. Weisenborn Page 2 Maximum 30-day average effluent values were also calculated for the plant assuming that the existing treatment system is improved. The improvements examined include: changing to non-chromate treatment of the cooling water so that the blowdown could be discharged directly, final filtration of the plant effluent, and a combination of the above. These alternatives have relatively low capital costs compared to building a totally new treatment system and would dramatically improve solids and BOD,, removal across the treatment system. The predicted effluent values for these cases are presented in Table II. If you need further information, please call.
