ALBANY, N.Y. (AP) — New York regulators will begin taking public comments on revised gas-drilling rules this week, though an extensive environmental review outlining the basis for those rules remains incomplete, and neither drillers nor environmentalists are happy lately with the state’s work on the issue.

Health and environmental groups have criticized Gov. Andrew Cuomo’s Department of Environmental Conservation for issuing the revised regulations before completing a health review or releasing the final version of a massive environmental impact study initiated in 2008. The state has had a moratorium on shale gas development since the study began.
