Topeka ? Gov. Kathleen Sebelius on Friday vowed to veto another bill approved by the Legislature that would require construction of two 700-megawatt coal-fired plants.

“I am disappointed that, again, we have the same elements in a bill that I cannot accept, and will not support,” Sebelius said in a prepared statement.

Lawmakers approved the bill as they lurched toward the end of the regular legislative session and prepared for a three-week break.

Last year, Kansas Health and Environment Secretary Roderick Bremby denied the $3.6 billion project in western Kansas, citing concerns with its annual emission of 11 million tons of carbon dioxide.

Since then, supporters of the plants have been trying to overturn the decision in the Legislature.

The new bill was approved in the House on Friday, 83-41, and then in the Senate, 32-7. The House vote total is one vote short of the two-thirds majority that would be needed to overturn a veto.

The new coal-fired plant bill is House substitute for Senate Bill 148.
