Except for electric utility systems constructed and operated as a

the sale, operation, maintenance, repairs, or relocation of
Government-owned utilities and utility systems and appurtenances
used in the administration of the Bureau of Indian Affairs. The
Secretary shall not execute a contract pursuant to this section
until he has submitted to the Committee on Energy and Natural
Resources of the Senate and the Committee on Natural Resources of
the House of Representatives a copy of the contract and a statement
of his reasons for proposing the contract, and until such materials
have lain before the Committees for sixty days (excluding the time
during which either House is in recess for more than three days)
unless prior thereto the Secretary is notified that neither
committee has any objection to the proposed contract.
