As California oil regulator seeks more money, legislators ask “Is this working?”

California’s oil and gas regulator has endured years of scolding from the Legislature for a lack of accountability, from environmentalists for allowing an industry to run roughshod over a state regulator, and from the federal Environmental Protection Agency for failing to enforce clean water laws.
