Gov. Susana Martinez is reshuffling the leadership of two state agencies because of the retirement of Energy, Minerals and Natural Resources Secretary John Bemis.
The governor named Environment Secretary F. David Martin to succeed Bemis, who is retiring Tuesday.
Bemis turns 62 this month and said he had long planned to retire at this time.
Martinez on Monday appointed Environment Department General Counsel Ryan Flynn to take over for Martin as cabinet secretary. Flynn has been the agency's top lawyer for two years.
Martin has worked for the governor since she took office in 2011. Martin holds engineering degrees from Texas Tech and New Mexico Tech, where he was an adjunct associate professor.
Bemis is an attorney with experience in oil and natural gas law.
