Notice that they propose to emit significant amounts of formaldehyde and other hazardous air pollutants. The actual permit and engineering evaluation are not yet posted on the WV-DEP website, so it would be a good idea to request it when it becomes available.
I am suspicious that they may be underestimating the emissions, they are very close to certain thresholds, and this modification only describes the "increase" in emissions from this modification, rather than the total emissions projected from the facility.
