Environmental Remediation
Unusual dark streaks and layers in the soil were discovered in June 2010 during excavation for the construction of a new storage building on the southeast portion of the site, near the gravel section of McCauley Street. Tests of the suspect material confirmed the presence of coal combustion byproducts (CCBs) in the soil, and the University notified DEQ of the situation in July 2010. The suspect soil in the building footprint was excavated and sent to a permitted landfill so that construction of the warehouse could be completed. UNC-Chapel Hill submitted the required site cleanup questionnaire to DEQ, and DEQ determined that the site was of low risk and could be voluntarily remediated under the REC program.
Further review of historical records determined that the CCBs were not new but dated back 50 or 60 years to the original coal-fired plant. At that time, CCBs accumulated on site as part of standard power station operations. CCBs from the present Facility meet current regulatory standards and are removed from the site to be recycled.
Although the suspect soil has been excavated and sent to a landfill, UNC-Chapel Hill volunteered to investigate and evaluate potential CCB impacts associated with historical operations at the Facility.
To participate in the REC program, in 2013 UNC-Chapel Hill hired Geosyntec Consultants, an environmental consulting firm, to oversee the investigation and remediation work in compliance with the REC program regulations.
REC activities are conducted under the guidance of a Registered Site Manager (RSM) who has been approved by DEQ to guide responsible parties through the REC program. Eric Nesbit, P.E., of Geosyntec serves as the RSM for the project. He is a Senior Principal Environmental Engineer with 25 years of program management experience executing environmental remediation actions, removal actions and remedial construction projects.

Events of 2008-2010
For many years, with only one building on site, the University used the Bingham Facility primarily for research support, swing space and overflow space. In 2008, the University adopted a long-range plan that had, at the time, a goal of consolidating preclinical research space used in blood and muscular dystrophy research and cardiovascular research into expanded facilities at the Bingham location. Toward that end, UNC-Chapel Hill installed a second wastewater treatment system and constructed a second research building for large preclinical models for human disease, with plans for four more buildings subject to securing adequate funds.
In 2009, a series of problems occurred at the facility, including a leak from a large holding pond that allowed some highly treated wastewater to reach a tributary of Collins Creek. The N.C. Department of Environment and Natural Resources (DENR) issued two violations for the incidents. The violations were for the method of discharge (leaking into the ground instead of being spray irrigated); they were not for contamination of the environment. Test samples taken from the monitoring wells on the site as well as the drinking water wells at the facility and at an adjoining property owned by the University have shown no pattern of contamination. The University stopped treating wastewater on site in late 2009 and instead began pumping and hauling untreated wastewater directly to OWASA for treatment.
The problems with the wastewater treatment coincided with substantial state budget cuts to the University, and the senior leadership at the University was faced with some difficult choices that ultimately led to cancellation of the expansion plans. The University had obtained funding for a third building, and it was already under construction. In the summer of 2010, The National Institutes of Health awarded UNC-Chapel Hill a $14.5 million grant from Recovery Act funds for the construction of buildings 4 and 5. However, there were no funds for building 6, and engineering studies indicated that the waste water treatment system installed in 2008—which had already been cited twice by DENR—could not accommodate the waste water that would have been produced from the operation of five buildings. UNC-Chapel Hill could not construct buildings 4 and 5 without investing many millions of dollars more to upgrade infrastructure at the facility. After a careful analysis, School of Medicine Dean William Roper decided to relinquish the $14.5 million grant from the National Institutes of Health and to cancel further expansion.
In February 2010, Associate Vice Chancellor for Research Bob Lowman was appointed to oversee the rehabilitation of the Bingham Facility and to establish an ongoing dialogue with the facility’s neighbors and with representatives of Preserve Rural Orange, an advocacy group in rural Orange County. He also led the effort to modify UNC-Chapel Hill’s existing wastewater treatment permit from DENR and mitigate any damage done to existing wetlands.
Lowman initiated several changes to reduce water usage and wastewater generation at the Bingham Facility. The original permitted wastewater treatment system (the one with no DENR violations) has now been refurbished and the newer failed system completely removed. Instead of plastic liners, the holding ponds have now been lined with clay, which meets requirements for the final soil filtration step of treatment. DENR approved a permit modification allowing these changes. Construction to implement these changes was completed by the middle of 2014.
