SAN FRANCISCO >> California's chief oil regulator announced his resignation on Monday after 17 months as head of the embattled agency, including a criticized episode in which he directed state workers to investigate the oil and gas potential of Gov. Jerry Brown's family ranch.
Steve Bohlen, the state's oil and gas supervisor, is leaving the Division of Oil, Gas and Geothermal Resources to return to the Lawrence Livermore National Laboratory research center, Brown's office said in a statement.
