  1. Shale Gas ExtractionWastewater Issues Panel Discussion Jan Marie Pickrel US EPA, Office of Wastewater Management August 2, 2011 Irving, TX EPA/RIVPA 27th Annual Pretreatment Workshop

  2. Safe Drinking Water Act • Underground Injection Control (UIC) • UIC Class II permitting guidance for use of diesel fuels in fracturing fluids • Clean Water Act • National Pollutant Discharge Elimination System (NPDES) • Pretreatment Water Regulation of Fracking Fluids

  3. 9 Natural Gas Service Companies • Chemical Composition of fluids used in fracturing • Data on impacts of chemicals on human health and the environment • Standard operating procedures at sites • Locations of sites where fracturing was conducted Voluntary Information Request

  4. EPA directed by Congress to Study • Draft to EPA Science Advisory Board (SAB): 2/8/2011 • SAB Review of Plan: 3/7-8/2011 • Initial Results to public: 12/2012 • Report of further research: 2014 • Scope: “Lifespan of Water,” focus on drinking water impacts • Report: “Draft Plan to Study the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources, ” February 2011 • EPA/600/D-11/001 www.epa.gov/research http://yosemite.epa.gov/sab/sabproduct.nsf/02ad90b136fc21ef85256eba00436459/D3483AB445AE61418525775900603E79/$File/Draft+Plan+to+Study+the+Potential+Impacts+of+Hydraulic+Fracturing+on+Drinking+Water+Resources-February+2011.pdf EPA Hydraulic Fracturing Study Plan
