The House Energy and Commerce Subcommittee on Energy and Power approved the North American-Made Energy Security Act (H.R. 1938) June 15 along party lines. The Keystone XL pipeline expansion project, which runs from Hardisty, Alberta, to an oil trading hub at Cushing, Oklahoma and then to the Texas Gulf Coast, was first proposed in 2008 to handle increasing oil volumes from the Alberta oil sands. Additionally, the Pipeline and Hazardous Materials Administration told the House Energy and Commerce Subcommittee on Energy and Power that the agency would study the impact of transporting tar sands through pipelines only if Congress requires it.
