 WFMD News. The Maryland-Piedmont Reliability Project came up for discussion during Tuesday's Frederick County Council meeting. That's a nearly 70-mile-long proposed power line from northern Baltimore County through Carroll County and into southern Frederick County. During public testimony, the council heard from Betsy McFarlane, who lives in Adamstown and is against the 500-kilovolt line. She said it would negatively impact the county's scenic beauty.
