OWENS-ILLINOIS <br /> • Glass Container 6�JI <br /> Division <br /> Sales Administration Center <br /> Pleasanton Office <br /> May 5, 1989 <br /> Ms. Donna Heran <br /> Environmental Health Division <br /> San Joaquin Local Health District <br /> 1601 East Hazelwood Avenue AY 1089 <br /> Stockton, CA 95201 <br /> RE: Underground Storage Tank Delisting Request C!.wlR ,r;✓,cNTALN `}, iH <br /> Quench Water Recirculation Sumps - Tracy Plant , <br /> Dear Ms. Heran: <br /> Per our telephone conversation 5/1/89, I have prepared a more <br /> detailed description of the quench water recirculation system <br /> which includes the two recirculation sumps. <br /> Water is used as a lubricant and coolant in the handling of <br /> molten glass. It flows continuously in the molten glass rejection <br /> chutes of each forming machine to quench tubs in the plant <br /> basement. The quench tubs collect and cool rejected molten glass <br /> for subsequent recycling. Quench water continuously overflows the <br /> glass collection tubs onto the floor and drains to the subject <br /> quench water recirculation sumps. Pumps continuously return the <br /> quench water to the forming machines from the process sumps thus <br /> completing the recirculation loop. <br /> Oil picked up by the recirculating water is continuously removed <br /> from the sump surface with oil skimmers. Recovered oil is <br /> collected in above ground tanks and routinely picked up by a <br /> registered oil recycler. Sludge, which gradually accumulates in <br /> the sumps, consists of glass fines and dirt. It is removed <br /> occasionally as a general maintenance practice, usually during <br /> major shutdowns. When removed, it is disposed of as hazardous <br /> waste due to its trace oil content. <br /> Hopefully, this description of our quench water recirculation <br /> system will clarify how the subject sumps function as a dynamic <br /> part of the continuous manufacturing process. They are not <br /> storage tanks as defined by underground storage tank regulations <br /> and explained by Joe Green in his letter of October 27, 1988. <br /> If I can be of further assistance to you or those reviewing this <br /> request for delisting, please contact me at (415) 463-7950. <br /> Very truly yours, <br /> Robert C.
