Senators Casey (D-PA) and Enzi (R-WY) have introduced legislation to address long-term liability issues presented by carbon capture and storage projects according to this press release from Senator Casey's office. Among other things, the "Carbon Storage Stewardship Trust Fund Act of 2009" would require private insurance for construction, transportation, injection and monitoring activities, and establish a federal trust fund from fees paid by facility operators to address claims for damages after a facility is transferred to the federal government.
