Portsmouth/Paducah Project Office - PPPO

Portsmouth/Paducah Project Office - PPPO Located in Lexington, Kentucky, the PPPO office lies between the Kentucky and Ohio Sites. EM began its cleanup program at the sites in the late 1980s.

Located in Lexington, KY, PPPO manages the DOE Environmental Management (EM) cleanup efforts at two gaseous diffusion plant sites – Portsmouth, Ohio, and Paducah, Kentucky. The Portsmouth/Paducah Project Office (PPPO) manages the Department of Energy (DOE) Office of Environmental Management (EM) cleanup efforts at two gaseous diffusion plant sites – Portsmouth, Ohio, and Paducah, Kentucky. The Department of Energy’s Portsmouth Gaseous Diffusion Plant in Piketon, Ohio, and its plant near Paducah, Kentucky, were built in the early 1950s to enrich uranium for national defense applications and later for commercial nuclear power plant fuel. The Portsmouth Site ceased enrichment by gaseous diffusion under a commercial lease in 2001, and the Paducah plant ceased production operations under a commercial lease in 2013. PPPO was established on October 1, 2003, to provide focused leadership to the EM missions at the two sites, encompassing decontamination and decommissioning (D&D), environmental remediation, waste management, and depleted uranium hexafluoride (DUF6) conversion. Although the PPPO Manager is based at the Lexington project office, frequent and routine site interactions occur between management and staff among all three locations. PPPO maintains a strong presence at the sites on a daily basis through its Portsmouth and Paducah Site offices. PPPO’s goal is to accelerate cleanup at the two sites, eliminating potential environmental threats, reducing the DOE footprint, and reducing life-cycle cost. The office provides consolidated management and services including:

* Project Management
* Risk Management
* Contract Management
* Business support services, including financial management, information technology, human resources, public affairs, legal, property management, security, safety and quality assurance

The vision of PPPO is to safely accelerate cleanup, ensuring protection of the public and environment, provide jobs for southern Ohio and western Kentucky, and work with the local communities to provide opportunities for economic growth.
