James B* Scarbrough, Chief Residuals Management Branch Region IV This memo is in response to your memorandum dated May 10, regarding the uae/reuae excluaion aa it relates to spent pickle liquor that is used aa a waatewater conditioner. In particular, O.3. Steel uses spent pickle liquor as a substitute for ferric chloride (as a waatewater conditioner) and adds it to their waatewater treatment ayatern; however, the Region and the State of Alabama question whether the use/reuse exelasion applies if the spent pickle liquor is discharged to a waatewater that is contained in an open unlined ditch. furthermore, you expect the build-up of BP sludge/precipitate on the bottom of the unit. You question whether you can regulate the unit as a hazardous waate surface impoundment. •bile we agree with your conclusion that you can regulate the unit as a hazardous waste impoundment, we do not agree with the logic that led you to that conclusion. The sludge that forms in the impoundment is a solid waate and if it is hazardous (i.e., exhibits one or more of the characteristics of hazardous waste), it is subject to regulation; thus, the impoundment would be aubject to hazardoua waste control. V we do not agree with your logic concerning the sion. the January 4 regulations (and preamble) to theso^vmajBlatioas indicates that spent pickle liquor that ia asael as>. a. wasteweter conditioner is considered to be covered under tms> mse/rense exclusion, provided that the material ia net apsevlatlveiy accumulated, see, for example, part I, Section III. B. (Secondary Materials That Are not solid Wastes), pg. «lf and part II, Section II. B. (Section 261.2(e)t Secondary Materials That Are not Solid Wastes Mnen Recycled), pg. <37* •» also addrees thia point indirectly in footnote 15 (pg. 62S) where it atatest ------- that wo do\not consider secondary taat are used aa was&etratar condtioner» to be -iMT^ °* this provision (use constituting provision).

Ms> th«rtifor«» cannot agr«« wit It you (or ths stats of JLlaJMsis) that this activity constitutes land disposal (under the Federal prograv).
