Topeka ? Legislative leaders on Thursday gave Gov. Kathleen Sebelius a take-it or stand-back proposal on the coal-fired power project.

Senate President Steve Morris and House Speaker Melvin Neufeld told Sebelius to accept two coal-burning plants in western Kansas or they would move to override her veto of the project.

Under the new proposal, the size of each of the units would be reduced from 700 megawatts to 600 megawatts.

Morris and Neufeld also set Wednesday as the deadline to hear from Sebelius on the new offer. That coincides with the first day of the 2008 Legislature’s wrap-up session,

Sebelius vetoed legislation that would have authorized two 700-megawatt coal-fired plants near Holcomb.

She cited concerns over the project’s annual emission of 11 million tons of carbon dioxide and its effect on climate change.

Morris and Neufeld said the new proposal was their final offer.
