CASPER, Wyo. (AP) — The top state regulatory agency for oil and gas development in Wyoming is about to interview candidates to become the next state oil and gas supervisor.

The interviews are planned Wednesday at Gov. Matt Mead's office in Cheyenne.

Mead is chairman of the commission, which has four other members. Interim oil and gas supervisor Bob King says the commissioners will interview seven candidates this week.

He says five candidates are either licensed geologists or licensed engineers in Wyoming.

The Associated Press reports the job has been vacant since Tom Doll resigned last summer. Doll quit following criticism for saying that some residents in the Pavillion area whose groundwater is contaminated are motivated by greed.

The EPA has been investigating whether hydraulic fracturing played a role in the contamination.
