Universal Service Sufficiency Act of 2000

Universal Service Sufficiency Act of 2000 - Amends the Communications Act of 1934 to remove, on the date of enactment of this Act, the interim cap on total nationwide loop cost expense adjustments (interim cap) contained in Federal Communications Commission (FCC) regulations. Prohibits the FCC from enforcing or reimposing such cap after such date.

Prohibits the FCC from: (1) enforcing individual caps imposed on carriers by orders of the FCC entered in connection with prior requests for study area waivers; or (2) imposing any new cap that would limit the per loop support calculated under current FCC regulations.

Requires the FCC to calculate: (1) that portion of the high cost support mechanism attributable to loops having costs in excess of 115 percent of the nationwide average; and (2) the nationwide average unseparated loop cost, taking into account the elimination of the interim cap pursuant to this Act.
