What is Superfund? “In response to hazardous waste from manufacturing facilities, processing plants, landfills, and mining sites, congress established the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) in 1980. CERCLA is informally called Superfund. It allows EPA to clean up contaminated sites. It also forces the parties responsible for the contamination to either perform cleanups or reimburse the government for EPA-led cleanup work. Superfund’s goals are to: • • Protect human health and the environment by cleaning up polluted sites; Make responsible parties pay for cleanup work; Involve communities in the Superfund process; and Return Superfund sites to productive use. ” Source: https: //www. epa. gov/superfund/what-superfund

Oak Ridge Reservation (USDOE) – ETTP Oak Ridge, TN Background/History • • 2, 200 -acres Home to WWII Manhattan Project K-25 Gaseous Diffusion Plant and other facilities in the processes for enriched uranium Enriched Uranium was produced by the plant for commercial nuclear power industry from 1945 to 1985 1987 – DOE terminated uranium enrichment operations, leaving ETTP with a legacy of contaminated buildings, soil, sediment, and groundwater that require remediation for the protection of human health and the environment Cleanup Challenges • • Contaminated buildings, soil, sediment, and groundwater from over 40 years of uranium enrichment Shallow groundwater contaminants: plumes containing VOCs; radionuclide technetium-99, TCE Construction debris and contaminated soils include elevated PAHs, selenium, chromium, mercury, PCBs, and lead Asbestos-containing material and metal debris remain buried onsite

Vision 2020 Innovation ETTP is close to national security, science, and energy research assets at ORNL and Y-12 Transportation The Metropolitan Knoxville Airport Authority is working with community partners to develop a general aviation airport at ETTP Growth More than 20 businesses currently call ETTP home, ranging from offices to manufacturing and warehouse tenants Environmental Conservation The BORCE at ETTP is a 3, 000 acre tract that provides habitat for endangered songbirds and recreational opportunities for the public.

Cleanup Progress: Torn down 400+ facilities “By 2020, workers will have taken down more than 500 facilities with a footprint spanning 113 football fields. ” 1000+ acres have been transferred 800 acres are ready for transfer OREM has transferred 14 buildings, emergency services, rail lines, most of the domestic water supply and sanitary sewer infrastructure, and completed modifications to most electrical infrastructure allowing for transfer

Recent Completions (May 2018) The Central Neutralization Facility demolition - Workers have finished the demolition project of the central Neutralization Facility, which once treated the sites' industrial waste water, five weeks ahead of schedule. - Constructed in mid-1980 s to treat wastewater from operations at the former uranium enrichment complex, the facility consisted of tanks, trailers, and other treatment systems used to filter and remove radioactive materials, metals, and suspended solids from wastewater at the site.

Recent Completions (April 2018) Removal of more that 4 miles of piping at ETTP • • OREM and UCOR finished removing more than 25, 000 feet of piping at ETTP that once transported uranium through a series of buildings during the enrichment process Crews disassembled, packaged, and shipped the tie lines for disposal

Investing in ETTP “Visitors who return to the site are amazed at the transformation. ” Companies investing in its future: Le. Mond Composites recently located in the area with plans to begin carbon fiber production this year MCLinc is renewing its commitment with the construction of a new 30, 000 sq-ft lab facility. Uni. Tech Services Group funded the refurbishment of ETTP’s barge area to receive and transport shipments using local river systems, adding to the site’s existing offerings and infrastructure. Nearly 20 companies to date are already located at the site.

Next Steps for ETTP • OREM is scheduled to finish demolition of remaining structures including support buildings, a waste incinerator facility, and former waste treatment facilities. • Construction has begun on the K-25 History Center, part of the Manhattan Project National Historical Park

Supporting East Tennessee • Overall spending by OREM and its contractors added ~$545 M to Tennessee's GDP in FY 14, including more than $422 M in Anderson, Roane, and Knox Counties • ~ 6, 200 full-time jobs were created in FY 14 of which ~4, 800 were in Anderson, Roane, and Knox Counties • Operations and activities generated ~$317 M in total personal income in FY 14; $278 M in threecounty region Source: https: //www. nrc. gov/docs/ML 18019 A 923. pdf

Portsmouth Gaseous Diffusion Plant (USDOE) Piketon, Ohio Why Portsmouth? - Built 1952 – 1956 y U. S. Atomic Energy Commission (Now USDOE) - Enriched Uranium by Gaseous Diffusion process from 1954 – 2001 - Cold War (1954 -1989): Nuclear Defense - Post Cold War(1989 -2001): Commercial Nuclear Power - Cleanup(2001 -current): Decontamination and Decommissioning, Reuse Cleanup Challenges: - The main contaminants contributing to excess lifetime cancer risks and hazards in waste include: degreasing solvent (TCE); heavy metals such as chromium and mercury; PCBs (from electrical transformer oils and ductwork gaskets); radioactive elements, particularly uranium and technetium-99; and asbestos in building materials.

Portsmouth Gaseous Diffusion Plant (USDOE) Piketon, Ohio Cleanup Progress: Groundwater Cleanup - 681 million gallons treated / 35, 000 pounds of TCE removed Landfills and Lagoons Closed - Five landfills containing construction debris, low‐level contaminated scrap metal, hazardous materials, sanitary wastes - A number of sludge lagoons, impoundments and oil biodegradation plots Waste Removed - More than 2. 8 million cubic feet of waste removed and disposed off‐site - 98. 8% RCRA waste reduction Demolition and Removal of Facilities - 40 buildings and facilities have been removed - X-326, X-333 Deactivation On Site Waste Disposal Facility Construction

Portsmouth Gaseous Diffusion Plant (USDOE) Piketon, Ohio Listening to the Community – PORTSFuture - Grant-funded study by Ohio University Voinovich School of Leadership and Public Affairs - 15 -month public participation process in Pike, Scioto, Ross, and Jackson counties to identify the community’s future-use preferences for the Portsmouth site post-cleanup - 1, 141 people voted on future-use scenarios - Most votes: - Nuclear power plant - Green energy production - Industrial park - National research and development

Portsmouth Gaseous Diffusion Plant (USDOE) Piketon, Ohio The End Goal “DOE’s mission at Portsmouth is to accomplish Environmental Remediation, Waste Management, Depleted Uranium Hexafluoride (DUF 6) Conversion, and Decontamination and Decommissioning. DOE’s goal is to accelerate cleanup, eliminating potential environmental threats, reducing the DOE footprint, and reducing life-cycle cost. ”

Uranium Barter at Portsmouth Unique program sells DOE’s stockpile of Uranium Hexafluoride (UF 6) on the open market for use in nuclear power plants. - All proceeds are used to fund the Portsmouth D&D project - Generated more than $1 billion for the project since beginning Positive Aspects: - Good uses of DOE assets - Minimizes impact to the tax payer - Dispositions DOE’s Inventory of UF 6 which benefits site cleanup Negative Aspects: - Market volatility causes budget issues at Portsmouth - Finite inventory

Next Steps for Portsmouth - Cut open 33 -ton steel components to remove internal material - More than 1, 700 components known as converters must be removed between two of the three major process buildings (X-333 and X-330) - Continue operations of groundwater treatment facilities - Cleanup groundwater and to continue disposition of uranium materials - Remove stored low-level and mixed waste streams contaminated with hazardous or toxic chemicals - Continue deactivation activities of various buildings Robotic arm equipment workers are training with to prepare for removing components formerly used to enrich uranium.

Supporting Southern Ohio Through the Joint Economic Development Initiative of Southern Ohio (JEDISO) the $855 K in Fluor-BWXT| Portsmouth business opportunity grants has led to $5. 5 M in matching dollars, which generated $186 M in investments creating 830 jobs and retaining an additional 5, 155 Jobs. Southern Ohio Diversification Initiative (SODI) has requested an 80 acre parcel for potential reindustrialization. Source: https: //portsmoutheic. com/Default. aspx
