State Issues Air Permit for Chemours to Install Thermal Oxidizer to Reduce PFAS Emissions

Raleigh

The N.C. Department of Environmental Quality’s Division of Air Quality (DAQ) has issued a permit to Chemours for the installation and operation of a thermal oxidizer/scrubber system to reduce air emissions of PFAS and GenX at the Fayetteville Works Facility.  The permit incorporates the requirements of the consent order signed on February 25, 2019 to install the thermal oxidizer by December 31, 2019 and reduce all PFAS emissions by 99% beyond the 2017 baseline.  

The permit requires the installation of the thermal oxidizer/scrubber system and the continued operation of the two carbon adsorbers installed in May of 2018.  Initial testing is required within 90 days of installation to confirm the 99% emission reduction.  Continuous monitoring systems and annual testing will verify compliance with the permit conditions.  The permit also requires the facility to operate under an Enhanced Leak Detection and Repair program.

After reviewing public comments on the draft permit, the hearing officer recommended additional plans for the installation, calibration and maintenance of the equipment used to monitor the pollution control devices and the equipment used in the leak detection and repair program. Those changes were incorporated in the final permit.

The final permit, permit review, director’s memo and hearing officer’s report can be found on DAQ’s website at: https://deq.nc.gov/chemours-permit-information
