LABORATORY wASTB CHEMICAL GENERATION PROCESS <br />Laboratory Waste Chemicals are generated from multiple operations throughout -the site. <br />The largest generators of this waste stream are Facilities Maintenance, Chemical Sciences, <br />Materials Physics, Biological Sciences, and Combustion Research. The Facilities <br />Maintenance Department is responsible for preventative and routine maintenance of the <br />facilities and grounds at SNL/CA. The other departments conduct collaborative research and <br />development with industries and academic institutions resulting in new and enhance <br />technologies that have both commercial and national security benefits. The generation of this <br />waste stream is from the use of chemicals or maintenance products in laboratory operations <br />and/or preventative and/or routine maintenance of the facilities and grounds. <br />SOURCE 1ZEDUCTION/POLLUTIONPBEVENTION EVALUATION <br />Description of Measure: <br />SNL/CA has implemented several administrative measures to reduce the generation of <br />laboratory waste chemicals: These measures include: <br />• Disallowing chemical purchases on a Pro -card <br />• ES&H review of each chemical purchase <br />o Utilizing a chemical exchange program <br />In addition Pollution Prevention staff review SOPS and all proposed new or revised <br />NEPA documents for activities conducted onsite. This allows feedback to be provided to <br />staff on possible waste reduction opportunities. The Pollution Prevention staff also <br />attends the biweekly Interdisciplinary Team (IDT) meetings -to ensure new projects or <br />modified projects implement waste reduction opportunities. All of the measures above <br />are ongoing and trending data for generation of this waste stream indicates as activities <br />increase, waste generation continues to decrease. <br />September 1, 2015 SB14 Plan <br />
