Liquid Gaseus Waste Operatins (LGWO) facilities treat liquid and gaseus waste streams frm OREM and the Office f Science peratins LGWO cmprised f 64 ORNL facilities and apprximately 20 miles f piping Treats cntaminated prcess water, grundwater and exhausts frm building and labratry ventilatin Cmprised f three waste treatment systems Liquid Lw-Level Waste System (120,000 gals/yr) Prcess Waste System (110M gal/yr) Gaseus Waste System (100,000 CFM flw) Gaseus Waste Liquid Lw-Level Waste Prcess Waste www.energy.gv/em 7
LLLW System treats highly cntaminated liquid wastes frm ORNL peratins The LLLW System cnsists f a series f dedicated tanks and undergrund piping used t cllect LLLW frm generating facilities at ORNL Waste is transferred t the LLLW Evapratr Facility fr vlume reductin Overheads frm the evapratr are treated at the prcess waste treatment cmplex The cncentrated LLLW is then transferred t strage tanks in the Bethel and Meltn Valleys fr lng term strage Prcess up t 120,000 gals/year LLLW Cllectin Facility Bldg 2099 LLLW Cllectin Facility Bldg 7966 www.energy.gv/em 8
The Prcess Waste System treats lightly cntaminated wastewater and grundwater Cllects wastewater frm ORNL generatrs thrughut Bethel and Meltn Valleys and grund water frm remediatin surces using a series f singlecntained hard-piping and pumping statins Pumping statins transfer the wastewater t a tank farm in each valley, where wastewater is stred until transferred t the Prcess Waste Treatment Cmplex Treatment prvided at tw facilities: Building 3608 (Nn-Radilgical Prcessing) Building 3544 (Radilgical Prcessing) Treats apprximately 110 millin gallns per year and including apprximately 2 millin gallns f leachate water frm EMWMF via tanker shipments 3608 Facility 3544 Facility www.energy.gv/em 9

Multiple landfill peratins at Y-12 are in place t manage ORR waste streams Waste Dispsal Facility EMWMF Classified Industrial Landfill Industrial Landfill Cnstructin/Demlitin Landfill Waste Received CERCLA waste t include legacy mixed lwlevel radilgical cleanup waste Industrial waste Industrial waste Cnstructin/demlitin debris www.energy.gv/em 15
Availability f nsite dispsal capacity fr lw-level waste (EMWMF) has been critical t the cleanup prgram s success 28-acre landfill that pened in 2002 Apprved by the Envirnmental Prtectin Agency and the Tennessee Department f Envirnment & Cnservatin in 2000 Receives lw-level radilgical and hazardus waste frm CERCLA cleanup f ORR and assciated sites Apprximate capacity f 2.18 millin cubic yards Apprximately 70% f the capacity has been used Landfill water is cllected, treated as necessary, and discharged www.energy.gv/em 16
Dispsal capacity fr classified waste is in place t supprt clean up EMWMF can take classified cntaminated waste A separate 4-acre landfill pened in 1989 receives sensitive waste frm ORR sites Permitted capacity f 89,000 cubic yards Apprximately 16% f the capacity has been used Leachate that is cllected frm the secnd, larger area, meets City f Oak Ridge sanitary sewer criteria and is discharged t the sanitary sewer lines at Y-12 www.energy.gv/em 17
An industrial/sanitary landfill n Chestnut Ridge serves all three Oak Ridge sites 26-acre landfill that pened in 1994 Receives ffice trash, cafeteria waste and ther sanitary waste frm the ORR sites Can accept minimally cntaminated demlitin waste Apprximate capacity f 2.1 millin cubic yards Apprximately 40% f the capacity has been used Leachate that is cllected meets City f Oak Ridge sanitary sewer criteria and is discharged t the sanitary sewer lines at Y-12 www.energy.gv/em 18
