Marshall County, W.Va. (WTRF) – If you’ll be driving through Marshall County in June, you may spot a few unfamiliar helicopters in the summer skies.

But don’t be alarmed—it’s a yearly process from a company we all depend on to keep our homes cool in West Virginia.

American Electric Power has miles and miles of power lines all across the state—and they have to protect all of them to keep our power running.

You’ve probably already seen crews out doing that work this month, but for the more remote areas, they’ll be doing a process called aerial spray.

Helicopters will be out applying herbicides on rights-of-way in Marshall County in June.

The company says it’s a process that needs to be done as trees grow up into the lines.

Those herbicides have been approved by the EPA and Department of Agriculture—and chances are you won’t even see the helicopters.

We don’t typically use aerial spray in areas such as housing developments or things like that. The reason that spray is used is because the area is very rural and very difficult to get to, so it’s very difficult terrain for other mechanisms to reach it, and so typically these are areas that are not very populated at all.
