I didn't read the whole thing but the gist I get is they want to possibly revoke the 902 to 928 ism band for ham and ism operations and reallocate it. I don't know how much danger there is of this happening because there is a shit ton of ham and part 15 ism users on this band in addition to government users.
But here is a pdf of the proposal.
