Gas news at a glance
Energy and Commerce Committee Ranking Member Henry A. Waxman, Natural Resources Committee Ranking Member Edward J. Markey and Oversight and Investigations Subcommittee Ranking Member Diana DeGette have released a report that summarizes the types, volumes and chemical contents of the hydraulic fracturing products used by the 14 leading oil and gas service companies. The report contains the first comprehensive national inventory of chemicals used by hydraulic fracturing companies during the drilling process. Key findings are: The companies used more than 780 million gallons of hydraulic fracturing products, with 2,500 products containing 750 different chemicals and other components. Between 2005 and 2009, the companies used hydraulic fracturing products containing 29 chemicals that are known or possible human carcinogens, regulated under the Safe Drinking Water Act (SDWA) for their risks to human health, or listed as hazardous air pollutants under the Clean Air Act. The BTEX compounds – benzene, toluene, xylene, and ethylbenzene – are SDWA contaminants and hazardous air pollutants. Benzene also is a known human carcinogen. The hydraulic fracturing companies injected 11.4 million gallons of products containing at least one BTEX chemical over the five-year period. Methanol was the most widely used chemical between 2005 and 2009. The substance is a hazardous air pollutant and is on the candidate list for potential regulation under SDWA. Isopropyl alcohol, 2-butoxyethanol, and ethylene glycol were the other most widely used chemicals. The companies used 94 million gallons of 279 products that contained at least one chemical or component that the manufacturers deemed proprietary or a trade secret. In many instances, the companies were unable to identify these “proprietary” chemicals. See the report at http://democrats.energycommerce.house.gov/sites/default/files/documents/....
