We've been hearing from a lot of you on the TV3 Facebook page about loud booms you've been hearing in Frederick County. In some cases, people tell us, it's shaking their homes.

"My husband was out in the living room watching TV, and I was in the computer room and boom," said Julie Cain of Winchester.

Julie Cain has lived in Winchester all her life. She says she heard the boom around 5 o'clock Tuesday.

"It shook the house a little bit," said Cain. "Mike, what is that and then he says I don't know? What was it? I don't know."

That's the question hundreds of you have. People told us they've been hearing booms from Gore to Shawneeland to Stephenson and Stephens City. Everyone's trying to figure out what is it.

"I think it could be they're building behind TGIF," said Cain.

Turns out that wasn't it. Perry Engineering is clearing the land for Chuck E Cheese's, and they say no blasting here. Shenandoah Valley Electric Cooperative says it's not them. First Energy says they're not doing anything in our area. Same with American Electric Power. Carmeuse Lime and Stone says you wouldn't hear their explosions.

While I was on the phone one of the possibilities that came up was with Dominion Power and right now they're working on the Mt. Storm Project, which is taking a transmission line from western West Virginia through Frederick and Clarke counties into Maryland.

Jim Norvelle with Dominion Power says, that they're using implosive sleeve devices. It melts the lines together and also causes a loud noise. He says, right now, that's going on about seven miles over the state line in West Virginia. This is one explanation for loud noises.

Soon, Dominion Power will be moving into Frederick County to do work on the line so it is likely people will be hearing more loud booms.

TV3 has confirmed from Dominion Power that the loud booms that people in Frederick County have reported hearing are from work being done by them in West Virginia.

A spokesman from Dominion Power in Richmond tells TV3 that a process used to melt lines together causes a booming sound. He says, that process is happening right now about seven miles west of the Frederick County border.
