Post-Decontamination Wipe Sampling <br /> Post-decontamination wipe samples were taken by ECS Refining Environmental <br /> Health and Safety staff to verify the effectiveness of the above decontamination <br /> procedures. A 12-inch by 12-inch wipe sample template was used to mark the area <br /> for wipe sampling. The wipe was a sealed sterile gauze pad supplied by the analytical <br /> laboratory. It was wetted with distilled water and wiped over the entire surface being <br /> sampled in the template area. The wipe was placed into the sample jar and labeled. A <br /> wipe sample was collected from the interior and exterior surface of the baghouse, for <br /> a total of two wipe samples, as required by the ECS Refining closure plan. All post- <br /> decontamination confirmation samples were analyzed for California-regulated metals <br /> (CAM 17). Please note that due to different laboratory test methods separate wipe <br /> samples were required for the mercury (Hg)testing and other 16 CAM analysis. On <br /> that basis,two wipe samples were taken side by side to constitute a single CAM 17 <br /> analysis. <br /> A field blank sample was taken by wetting one wipe at the baghouse site and placing <br /> it into the sample jar. Only one blank sample was taken, so the blank was not <br /> analyzed for mercury, but only for the other sixteen regulated metals. <br /> 4. Post-Decontamination Wrapping and Transportation <br /> The Destoner Baghouse was removed and packaged for transport the week of July 15, <br /> 2014. The equipment was transported using a bill of lading as documentation and was <br /> sent to the Stockton facility on July 28, 2014. <br /> Attached to this report are the following documents: <br /> • Wipe sampling results summary, with a comparison to EPA health-based <br /> benchmarks <br /> • Wipe sample analytical report from TestAmerica laboratory <br /> • Copy of the bill of lading used to transport the baghouse to Stockton <br /> • Signed facility closure certification statement <br /> The closure plan and cost estimate for Regenesys Glass Processing will be modified to <br /> reflect the installation of this additional equipment. <br /> 705 Reed Street Phone:(408)200-7000 <br /> Santa Clara,CA 95050 Fax:(408)988-5154 <br /> Page 2 <br />
