In August 2011, Chu praised an advisory panel’s report on curbing the environmental risks of natural-gas development. Chu responded to the panel’s report on hydraulic fracturing. Hydraulic fracturing breaks up rock to get more oil and gas out of the ground. The report recommendations include: greater data collection of air and water data, “rigorous” air pollution standards and mandatory disclosure of chemicals used in the hydraulic fracturing process. “The report ... recommends a range of tools for implementing these measures, including regulation, continuous improvement in best practices by industry, and ongoing research and development,” Chu said in a statement. “I will be working closely with my colleagues in the Administration to review the recommendations and to chart a path for continued development of this vital energy resource in a safe manner,” he added.
