With the least stringent regulations of any state with shale production, critics are calling on Virginia to clear up confusion over local fracking bans and complete two reviews of its oil and gas regulations, one of which has been pending since 2004. An in-state regulatory review, underway since 2013, is approaching its final stage but has no deadline. It’s being conducted by a Gas & Oil Regulatory Advisory Panel revved up after Democratic Gov. Terry McAuliffe took office in early 2014. Recommendations from that review depend on a last round of public comments and final approval by McAuliffe.
