Federal VHF Low Band - TVA?

A couple of years ago I asked MT readers for any information on current federal (non-military) agencies that are still using VHF low-band (30-50 MHz). Unfortunately I did not receive any information, but I recently stumbled across some discussions on Radio Reference about line crews from the Tennessee Valley Authority, (http://www.tva.gov/) still using low band.

Here are the TVA Lo-Band channels and locations that I have in my database:

38.97 - AL, MS, US
38.98 - AL, KY, MS, NC, TN, US
40.50 - KY, MS, TN, US
40.57 - US
40.61 - US
40.62 - AL, KY, MS, NC, TN, US
40.73 - US
40.74 - AL, KY, MS, NC, TN,US
40.75 - US
40.85 - US
40.87 - MS, US

Can anyone in the states listed give these a listen and let us know if they are active?
