New Environmental Protection Agency standards that aim to cut air pollution from oil and natural gas produced through hydraulic fracturing have received tempered praise from industry groups and mixed reviews from environmental organizations. 

The energy industry prefers the rule's Jan. 1, 2015, compliance date to an earlier EPA proposal's tighter deadline. Environmental organizations call the regulation, announced on April 18, a good first step in improving public health but say EPA gave in too much to industry by extending the compliance deadline.
