Thuy Tran [EH] <br /> From: Thuy Tran [EH] <br /> Sent: Wednesday, November 21, 2012 2:34 PM <br /> To: `benson.cuthbertson@nsg.com' <br /> Subject: HW tank closure <br /> Attachments: HWTankClosureCertificationhwf1249.doc <br /> Hello Ben <br /> Just wanted to follow up with our phone call conversation. <br /> It appears that the tank used for Excluded Recyclable Material—lubricating oil would not need a Professional Engineer <br /> to perform a Hazardous Waste Tank Assessment.An HW Tank assessment applies to tank systems used for transferring, <br /> storing and treating hazardous waste CCR 66265.190. <br /> The tank used for recycling lubricating used oil should be properly labeled as"Excluded Recyclable Material' rather than <br /> "Hazardous Waste". <br /> Facility must keep an operating log and copies of certification forms, as specified in HSC 2520.19(c). <br /> Ensure the Excluded Recyclable Material Report is submitted to EHD every 2 years, as specified in HSC 25143.10(a). <br /> The dismantled Sulfuric Acid tank closure/disposal should be followed as specified in CCR 67383.3. <br /> The HW Tank Closure Certification form is attached to email. <br /> If you have any questions, please give me a phone call. <br /> Thuy Tran, Sr. REHS <br /> Senior Registered Environmental Health Specialist <br /> San Joaquin County Environmental Health Department <br /> 1868 East Hazelton Avenue Stockton, CA 95205-6232 <br /> Phone (209) 468-8257 <br /> Fax(209) 468-3433 <br /> htW://www.sigov.org/ehd <br />
