Members of the Shale Gas Subcommittee of the Secretary of Energy Advisory Board testified before the Senate Energy and Natural Resources Committee October 4 that industry practices for extraction of natural gas from shale need constant improvement and a systemic spread of best practices to protect the environment, but that states should lead improvements in the regulation of shale gas, including the associated hydraulic fracturing. The advisors said the same thing to Energy Secretary Steven Chu in August and will issue another report with more detail on their 20 recommendations in the next six weeks.
