This summer, UCOR supported a modification to ETTP’s National Pollutant Discharge Elimination System (NPDES) permit, reducing the number of regulated outfalls from 56 to 43. This change lowers DOE’s environmental liability and reinforces responsible stewardship of taxpayer dollars.
The effort—led jointly by UCOR labor and subcontractors—involved evaluating each outfall to determine which locations already met environmental standards and required no additional restoration. Outfalls that demonstrated compliance were removed from the permit eliminating DOE’s obligation to monitor them.
Outfalls are designated points where water, including stormwater collected across the site, returns to the surrounding environment. Due to ETTP’s past mission as a gaseous diffusion plant during the Manhattan Project, these discharge locations were historically monitored by regulators and DOE to ensure water leaving the site met environmental requirements.
In 2024, UCOR and DOE’s Oak Ridge Office of Environmental Management achieved Vision 2024, completing soil remediation and nearly two decades of major fieldwork at the East Tennessee Technology Park. With remediation complete, UCOR’s mission has shifted toward long‑term land management—ensuring stable drainage and restoring outfalls before they can be removed from the NPDES permit. Restoration activities include cleaning drainage structures, repairing erosion, and reestablishing vegetation. Once restored, an outfall no longer requires active regulatory oversight, removing associated environmental liability.
Reducing unnecessary restoration and DOE’s need to monitor outfalls minimizes long-term maintenance and reporting costs, delivering significant savings to taxpayers. It is also a key step in preparing the property for future transfer and redevelopment.
To date, 2,555 acres have been transferred, with another 185 acres in process at ETTP. Redeveloped property now supports 25 private businesses and property owners, approximately $10 billion in investment, and 2,500 new jobs. An additional 3,500 acres are designated for conservation and natural areas, and 100 acres preserve nationally significant historic resources.
