safe disposal of wastewater from hydraulic fracturing, has partnerships with other administrations and companies to reduce the air emissions from hydraulic fracturing, particularly from methane employed in the process, and tries to ensure both compliance to regulatory standards and transparency for all stakeholders implied in the implementation process of hydraulic fracturing. On August 7, 1997, the Eleventh Circuit Court ordered EPA to reevaluate its stance on hydraulic fracturing based on a lawsuit brought by the Legal Environmental Assistance Foundation. Until that decision, the EPA deemed that hydraulic fracturing did not fall under the rules in the Safe Drinking Water Act. While the impact of this decision was localized to Alabama, it forced the EPA to evaluate its oversight responsibility under the Safe Drinking Water Act for hydraulic fracturing. In 2004, the EPA released a study that concluded the threat to drinking water from hydraulic fracturing was “minimal”. In the Energy Policy Act of 2005, Congress exempted fractured wells from being re-classified as injection wells, which fall under a part of the Safe Drinking Water Act that was originally intended to regulate disposal wells. The act did not exempt hydraulic fracturing wells that include diesel fuel in the fracturing fluid. Some US House members have petitioned the EPA to interpret "diesel fuel" broadly to increase the agency's regulatory power over hydraulic fracturing. They argue that the current limitation is intended not to prevent the use of a small subset of diesel compounds, but rather as a safety measure to decrease the probability of accidental groundwater contamination with toxic BTEX chemicals (benzene, toluene, ethylbenzene and xylenes) that are present in diesel compounds. Congress has been urged to repeal the 2005 regulatory exemption under the Energy Policy Act of 2005. The FRAC Act, introduced in June 2009, would eliminate the exemption and might allow producing wells to be reclassified as injection wells placing them under federal jurisdiction in states without approved UIC programs. In November 2012, the Centers for Disease Control and Prevention (CDC) was considering to study a potential link between fracturing and drinking water contamination. Republican House energy leaders advised Department of Health and Human Services (HHS) Secretary Kathleen Sebelius to be cautious in the study. They argued the study, if not properly done, could hinder job growth. They worried that the study could label naturally occurring substances in groundwater as contaminants, that the CDC would limit hydraulic fracturing in the
