CHEYENNE, Wyo. (AP) — Ken Salazar's office says the Interior secretary is about to make a major public announcement concerning a new milestone in the development of renewable energy on public land.

Interior officials aren't saying what Salazar is going to announce but it may have to do with wind energy. The event will take place at a wind energy lab at Laramie County Community College in Cheyenne. The college is one that offers job training for the wind power industry.

U.S. Fish and Wildlife Service chief Dan Ashe plans to be at the Tuesday morning announcement. Gov. Matt Mead's office says the governor was invited but is unable to attend.

Salazar visited Cheyenne last year to announce plans to lease vast amounts of federal coal in the Powder River Basin in northwest Wyoming.
