The Illinois Department of Natural Resources has finally released the set of proposed rules for the oil and gas drilling process known as fracking. Environmentalists have criticized draft versions of the rules as being too lenient, while industry groups have bemoaned the delay that has meant no drilling permits have been issued for sites in southern Illinois. The IDNR report has been delivered to the Joint Committee on Administrative Rules, which has 45-days to act or let the rules take effect as they are.
