NAVASSA — Another community meeting and drop-in information session is on the books in Navassa to discuss the final cleanup plan for Operable Unit 2 of the Navassa Superfund site. 

The U.S. Environmental Protection Agency, the North Carolina Department of Environmental Quality and the Multistate Trust will host the meeting on October 18 at the Navassa Community Center.

The community meeting from 6 p.m. to 7 p.m. will be virtual and in-person while the drop-in information session will occur only in-person from 7 p.m. to 8 p.m. 

Along with the continuing cleanup effort, meeting topics will include the upcoming sampling in the marsh, site marketing and future use, and the Moze Heritage Center land donation.

The plan is part of the three agencies efforts to cleanup the 100-acre Superfund site, which was used as a creosote-based wood treating facility operated by Kerr-McGee from  1936 to 1974. In 2010, groundwater, soil, and sediment contamination by creosote-related chemicals led the EPA to add the property to the National Priorities List of federal Superfund sites. Site contamination does not currently threaten people living or working near the Superfund Site.

The land is broken into five operable units, one being groundwater. The agencies are remediating the units from one to four, or less affected to most. In April 2021, EPA issued a record of decision explaining that the selected remedy for the 20-acre OU1 is no action, paving the way for future reuse of the land.

The EPA signed a record of decision on the OU2 remediation on Sept. 28. 

OU2 is the 15-acre area south of OU1 and north of the historical wood treating operations process area. OU2 was used for treated and untreated wood storage by Kerr-McGee and its predecessors. 

The EPA selected Alternative 3 — removal of contaminated material, on-site reuse/consolidation and off-site disposal — as the final remedy for OU2 based in part on community input, including environmental justice considerations, according to an EPA press release.  

Both the community meeting and drop-in information session will be held at the Navassa Community Center at 338 Main Street. The meeting can be joined by Zoom or phone by calling (301) 715-8592. Use meeting ID 946 584 8922# and passcode 664564#.
