/ August 29, i960 Mr. 3. Faclni Engineering Department Portable Compressor Division Chicago Pneumatic Tool Company Manufacturing Division Franklin, Pennsylvania Dear Mr. Faclnit Your letter to Hr. James D. Wright of our Company has been forwarded to me for answer. Your questions are difficult to answer in a generalized way. - As you know, theGjydrayl fluids are Insoluble in water as well as heaviar tKilTwater. Unlaae theee matarlala are strongly emulsified they will link to the bottom of any receiving stream and as such will not give rise to the typical pioture of oil pollution. If the material la die charged In large concentrations it will adversely effect the organiama In the bottom of the receiving stream which will effect the aquatic life in the stream. This effect will probably not be any mors serious than the affect of heavier petroleum oils. If large concentrstione of these materials are contemplated In your discharge stream they could probably be removed by emulsion breaking and settling. This can be cooa^llshed by gravity separation if the emulsions can be readily broken. We have had no experience with any regulatory agency con cerning the discharge of theee materials. I would imagine that these agenoles would frown on the discharge of large quantities or any type hydraulic fluid. __ Based on the toxicity studies of these fluids with laboratory animals I would not expect them to be very toxic to aquatic U f a . On the other hand, this ia a surmise on my part since we have no teats on aquatic animals. In summary I would lika to say that if small quantities of these material are accldnetally spilled Into a receiving stream there would probably be no harmful effeot. If, on the other hand, a great deal of the material was spilled some readily idontlflabia damage might ensue. HONS 091044 Mr. S. Faoini -2 - August 26, i960 I realize that this information is somewhat sketchy but as you know the pollutlonal potential of any individual die* charge can only be measured by the faotors that Influence that particular discharge. These faotors would Include the amount of fluid discharged, the total dilution water available in the effluent stream, the total volume of water in the receiving stream and the condition of the fluid in the effluent stream - emulsified or not. We would be glad to discuss any individual occurrences that you might have in mind. If we can be of any further help, do not hesitate to let us know. Slnoerely, Jack T.
