I noticed that section 3.3.4.11,V1,discharge valve,states that the neutralized discharge water is <br /> discharged off-site. This section does not indicate the system that receives the discharge water. Please include more detail to this section and indicate the system <br /> that receives the discharged water off site. <br /> Please also upload the latest version of the procedure to CERS. <br /> Thank you, <br /> Garrett Backus,Ld.Sr.REHS,CUPA programs <br /> San Joaquin County Environmental Health Department <br /> 1868 E Hazelton Ave,Stockton,CA 95205 <br /> (209)468-2986 abackusG�sjaoyora <br /> hftps://www.s'aov.ora/departmentlenvhealth/ <br /> Please note my email has changed. <br /> SANJOAQUIN <br /> COUNTY <br /> Greatness grows here. <br /> From:Chris Colbert<ccolbert(@Iustrecal.com> <br /> Sent:Thursday,April 11,2019 3:15 PM <br /> To:Garrett Backus[EH]<gbackus(@sicehd.com> <br /> Subject:RE:Hazardous Waste Inspection Report-treatment <br /> Here is the updated procedure. <br /> From:Garrett Backus[EH]<gbackus(@s4cehd.com> <br /> Sent:Thursday,April 11,2019 3:12 PM <br /> To:Chris Colbert<ccolbert(@Iustrecal.com> <br /> Subject:RE:Hazardous Waste Inspection Report-treatment <br /> Looks like I received eight SDSs but I don't see the updated procedure attached. <br /> From:Chris Colbert<ccolbert(@Iustrecal.com> <br /> Sent:Thursday,April 11,2019 3:03 PM <br /> To:Garrett Backus[EH]<gbackusRasjcehd.com> <br /> Subject:RE:Hazardous Waste Inspection Report-treatment <br /> Hello Garret, <br /> Got it. Here is the updated procedure with toxic removed and some additional concentration details. The SDS are attached as well. The etch and frost SDS are for <br /> the solid form as purchased prior to becoming a solution or rinse. Let me know if you need anything else. <br /> Best Regards, <br /> Chris Colbert <br /> Vice President Operations <br /> Lustre-Cal Corporation <br /> (209)370-1600 Main <br /> http://www.lustrecal.com <br /> From:Garrett Backus[EH]<gbackusPsjcehd.com> <br /> Sent:Wednesday,April 10,2019 4:33 PM <br /> To:Chris Colbert<ccolbert(allustrecal.com> <br /> Subject:RE:Hazardous Waste Inspection Report-treatment <br /> Something that's toxic by the hazardous waste definition probably cannot go through your treatment system under the current permit. I'd like to get the SDSs or <br /> other hazardous waste determination data to see if they indicate toxicity. If they are not toxic I'd take the"toxic'wording out of the procedure. <br /> Garrett Backus,Ld.Sr.REHS,CUPA programs <br />
