RICHMOND, Va. (AP) — The Virginia House passed a bill Monday that would phase out two costly coal tax credits that a state investigation recently found generate economic losses for the state.

On a 54-45 vote, the chamber approved the measure from Del. Sally Hudson. The bill still must pass the Senate before it can go to the governor.

A similar measure being sponsored by a Democratic senator hasn’t yet received a vote.

The incentives are designed to encourage coal production and coal use, and aid the struggling economy of southwest Virginia. A report last year from the state’s legislative watchdog agency found that they have created a net loss for the state.
