(AP) — The former prosecutor against ex-coal company chief Don Blankenship expects him to serve his full, one-year sentence in a minimum-security federal prison.
Former U.S. Attorney Booth Goodwin made the comments Thursday.
Assistant U.S. Attorney Steven Ruby confirmed that time off for good behavior applies only to terms more than a year.
On Wednesday, Blankenship was sentenced to the maximum penalties of a year in prison and a $250,000 fine for conspiring to willfully violate mine safety standards at Upper Big Branch Mine.
The southern West Virginia coal mine exploded in 2010, killing 29 men.
A jury convicted him of the misdemeanor on Dec. 3.
Judge Irene Berger declined to let Blankenship stay free on a $1 million bond while he appeals the case.
Goodwin left office after Blankenship's conviction to run for governor.
