"Recycled", not "Reused"
Seeing as this is a government agency, the use of the word "recycled" leads me to believe that the hardware was sent to an EPA recycled to be either destroyed (the usual with fed drives) or maybe, possibly, refurbished and sold.
I worked for one of these recyclers for 3 years, and the standard we used with 3 letter agencies was to run a DOD wipe, then destroy the drives. (In one case, I got to plug it in, spin it up, and hit it with a hammer to pulverize the platter. In front of the "client" :) )
