Backus, Garrett [EHD] <br />From: Backus, Garrett [EHD] <br />Sent: Tuesday, October 26, 2021 11:09 AM <br />To: Scott Renfrew; Florido, Elianna [EHD]; Tony Grizelj <br />Cc: Rob Ashe; Chad Yelm; Ericson Mercado; Henry, Michelle D [EHD]; Manzo, Elena K. <br />[EHD]; Baker, Lydia [EHD] <br />Subject: RE: Metal Finishing Solutions RTC Follow Up <br />Hi Scott, <br />I've reviewed the waste analysis on rinse tanks 3,4,6,7,9,10, and 11. Tank 9 contained 470 mg/L of fluoride which <br />exceeds the hazardous waste limit of 180 mg/L. Let us know how the Tank 9 waste is being handled since the treatment <br />system does not remove fluoride. <br />Garrett Backus, Ld.
