Frederick County residents will soon be reminded that air doesn’t recognize state borders.

Less than a 15-mile drive from Brunswick in Ranson, West Virginia, a 460,000-square-foot mineral wool insulation manufacturing plant has been proposed and is under preliminary construction. In the past year, debate on the project has transformed from local objections to the location of the plant near schools, to one on possible air pollution crossing state lines.

The filthy and antiquated coal and fracked gas burning technology Rockwool hopes to employ here would not be permitted in their home country of Denmark. It should not be permitted here. Their proposed plant would dwarf that of the Halltown Paper Plant (which has actually improved its emissions in recent years.). Rockwool would significantly increase deadly PM2.5 air pollution and threaten the ground water resources of the entire region. Worst possible neighbor!


Why no mention that Kaltenbaugh is the chair of the Frederick County Sustainability Commission and a climate change activist? The fact that a vocal bunch of people show up at meetings is not a clear indication of who is for or opposed to Rockwool. There were a lot more Clinton signs throughout the county but Trump won with 68% of the vote. The squeaky wheel is noisy but just one wheel of four. I went to the open house and met with the Rockwool people. I asked questions and learned about the process and how that not just meeting EPA and WVDEP requirements, but are exceeding them. Too many alarmists out there. Research it yourselves.


Call me cynical, but I would consider any information a corporation provides about its operations suspect.

I have no opinion at this time. I only just now did some quick research. Rockwool or mineral wool itself seems relatively safe -- it is the manufacturing process that seems potentially hazardous. This article is informative and seems balanced:


Rookwool is bad but 2 miles down is the Halltown Paperboard which is ok? Seems to be some picking and choosing here among the local residence.


Sulfer dioxide! The people in that region better hope their de-sulphurization technology works if not it would compare to living with someone in close quarters eating hard boiled eggs and swelling beer.

Only a fool would look to the EPA to protect anybody from anything nowadays.


This (and just about everything else) depends on good laws and even better enforcement. Perhaps the new Congress can look to better enforcement than the White House seems to want.
