Backus, Garrett [EHD] <br /> From: Backus, Garrett [EHD] <br /> Sent: Monday, August 10, 2020 3:41 PM <br /> To: Robert Calverley <br /> Cc: Jenny Calverley <br /> Subject: RE: Hazardous Waste inspection photos <br /> Robert, <br /> The sample shows 6 mg/liter Cu which is less than the hazardous waste limit of 25 mg/liter for Copper so the sludge <br /> waste is non-hazardous according to the fish bioassay test and the two heavy metals tests. <br /> I can close violation 102. The sludge waste can be handled as non-hazardous waste . If the waste stream changes due <br /> to manufacturing or raw material changes you'll need to do another hazardous waste determination. Keep this lab data <br /> in your facility file. <br /> Thank you, <br /> Garrett Backus, Ld.
