"... the amendment be subject to a 60-vote threshold and if the amendment achieves that threshold, it be agreed to," Reid said, making the point that if the amendment does not achieve that threshold, that it was to be withdrawn.

"... with respect to each amendment the Senate proceed to vote upon disposition of all amendments, the general debate time, the bill be read a third time, the Senate proceed to pass on the bill and the passage of the bill requires 60 votes," Senator Reid said.

The top Senate leader said that the final vote on the Bill will not come until after 7 pm on Wednesday (after 4:30 am IST on Thursday).

"At 7:00 pm (Wednesday Washington Time) that the House (Senate) resume to HR 25 that the time is equally controlled between the leaders and designees," Reid said.

He said "Senate proceed to vote on the motion to concur on the House amendment to the Senate bill upon the disposition of the House message."

"The Senate resume consideration of HR 7081, the India-US cooperative agreement, and that the amendment be voted in the order of offered on Wednesday October 1, there be two minutes of debate prior to each vote equally divided and controlled and after the vote on each sequence, the succeeded votes be 10 minutes in duration," Senator Reid said.

Unlike the House of Representatives which needed a two-thirds majority, the Senate requires only a simple majority to approve the legislation.

A clearance in the Senate will allow India and the US to sign the landmark accord and resume bilateral nuclear trade. India has already signed a civil atomic cooperation agreement with France, ending 34-years of nuclear isolation.
