Do not click links or open attachments unless you recognize the <br /> sender and know the content is safe. <br /> Mr. Backus—as discussed previously,Thatcher Chemicals in Stockton, California has completed the cleaning and <br /> decontamination of 4 poly tanks at their facility. After cleaning, these tanks were cut into large pieces and stored on <br /> pallets pending your acceptance of the closure certification. To evaluate potential surface contamination on the pieces, <br /> we measured surface pH at 6 locations on each of the 15 pallets (75 total measurements), all results were between 5—7 <br /> Based on this, I have completed and signed the tank closure certification form for all 4 tanks (included in the attached <br /> memo). Once we receive your acceptance of the closure certification,Thatcher will either recycle or dispose of this <br /> material <br /> Please let me know if this is acceptable to you, or I would be happy to provide additional information. <br /> Jim <br /> James Kapin, MPH, CIH, CSP I Director of EM Services <br /> ACTenviro <br /> Tel.
