waste, with half-lives greater than 20 years, except for: (1) high-level radioactive waste,

(2) waste that the Secretary of Energy has determined, with the concurrence of the

Administrator of the Environmental Protection Agency, does not need the degree of

isolation required by the 40 CFR Part 191 disposal regulations; or (3) waste that the
