This morning, the House Ways and Means Committee passed its plan to prop up the Highway Trust Fund — which pays for transit and bike/ped infrastructure in addition to roads — until May 2015. A few hours later, the Senate Finance Committee approved a plan of its own, with no deadline attached.

Sens. Ron Wyden (D-OR) and Orrin Hatch (R-UT), the two top dogs on the Finance Committee, agreed on a bill that matches the dollar amount in the House bill — $10.8 billion. Wyden’s original proposal had the bill expiring December 31, but the final bill didn’t have any deadline in it at all. The fact that the Senate matched the House bill dollar for dollar, however, indicates that they’re leaving the door open to extend it all the way to May 31, like the House.

Sen. Barbara Boxer, chair of the Environment and Public Works Committee, said she was grateful to the Finance Committee for agreeing on a “shorter-term patch” and still hoped to pass a long-term bill by December, though it’s unclear that’s what the Finance bill does.   

As I said yesterday, an extension through May would be a huge blow to Democrats, who would prefer to see the extension expire by the end of this year in hopes of forcing action on a long-term bill while Democrats still control the Senate.

The Senate bill adds in some of the House’s pay-fors too, including $2.7 billion raised from “pension smoothing,” which is generally viewed as a gimmick that doesn’t raise any actual money long term. The House plan takes $6.4 billion from pension smoothing, but Wyden wanted to reserve some of that money — fictitious though it may be — for other purposes.
