House Republicans on the Transportation and Infrastructure and Energy and Commerce Committees are working to iron out differences between two bills that would reauthorize federal pipeline safety programs. There are currently three pieces of legislation aimed at reauthorizing the pipeline safety programs that expired in 2010, two in the House and one in the Senate. House Republicans hope to have a single House bill before the end of the year, as each of the two committees has passed its own version (H.R. 2845 and H.R. 2937) this fall. The Senate unanimously passed S. 275 October 17.
