Although the Interim Committee on Energy and Telecommunications in 2007 began to examine the possibility of developing draft carbon storage legislation for introduction in the Montana legislature in 2009, the interim committee could not reach necessary consensus. It did, however, issue a comprehensive Report. Notwithstanding this, several bills were introduced in the 2009 legislative session, one bill on the House side (the Governor’s bill) and three on the Senate side. One bill, Senate Bill 498 ultimately passed the Senate and the House and was signed by the Governor on May 6, 2009, becoming law. Most elements of the law will not be effective until the state is granted primacy authority by EPA under Rules for CO2 Storage currently being developed by EPA and not expected until 2011. Further development of rules in Montana is expected to await the grant of primacy authority by EPA.
