Modification to Air Permit to Construct

Quick Links

What Happened?

Background

Rockwool’s original Air Permit to Construct was poorly noticed and went unopposed by the public in 2017. When the true nature of the plant’s operation and the permit were discovered by the public in 2018, it was too late—the Air Permit to Construct had been approved.

Again, the Foundation submitted technical comments prepared by our specialized attorney and experts.

The WVDEP issued the final permit in November 2023. Both the Foundation and Rockwool appealed the permit to the Air Quality Board. The Foundation was also granted intervenor status in Rockwool’s appeal. Rockwool’s appeal sought to increase the amount of air emissions they could release and reduce protections. Specifically, Rockwool sought to markedly increase the amount of PM 2.5 that could be released. The Foundation’s appeal sought to improve transparency and improve protections.

The Air Quality Board determined that Rockwool would be required to adhere to the PM2.5 limit that the DEP had imposed with no increase.
