Redevelopment at the Site

The 1.5-acre North Carolina State University (Lot 86, Farm Unit #1) Superfund site is located in Raleigh, North Carolina. The site served as a waste disposal area for North Carolina State University science laboratories and agricultural research facilities. From 1969 to 1980, the University disposed of solvents, pesticides, heavy metals, acids and some low-level radioactive laboratory wastes in trenches located on a portion of the site. EPA added the site to the Superfund program’s National Priorities List (NPL) in 1986.

EPA’s 1996 cleanup plan included the treatment of contaminated soil. Cleanup also included the removal and treatment of contaminated groundwater. The site’s potentially responsible party completed soil cleanup in 1999. Treatment and monitoring of contaminated groundwater continues under EPA oversight.

Since 2007, Carolina Solar Energy LLC (CSE) has operated a 70 kW photovoltaic solar generation project on the site. The project has been designated a Solar "Brownfields to Brightfields" Technology Demonstration Project by the U.S. Department of Energy. CSE sells the electricity generated by the 12 solar arrays back to Progress Energy. CSE will own and operate the solar energy system for 20 years under a lease from the State of North Carolina.

Economic Activity at the Site

As of December 2019, EPA had data on one on-site business. EPA did not have further economic details related to this business. View additional information about redevelopment economics at Superfund sites.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.

EPA uses institutional controls to reduce exposure to contamination by restricting access to contaminated areas. Institutional controls can also guide human behavior through legal mechanisms such as deed restrictions and public health warning signs.
