33 Policy Options Study economic and environmental advantages and disadvantages of developing shale gas in North Carolina – USGS/NCGS Resource Assessment, Spring 2011 Learn from other States, the industry, EPA, and the public – States are primary regulators of this industry Develop a comprehensive regulatory program/avoid inefficient, fragmented regulatory program

34 Policy Options 2010 UNC-CH-Duke Water Allocation Study recommended a moratorium on water withdrawals for shale gas until the Division of Water Resources completes hydrologic models for the appropriate river basins to ensure that water withdrawals will not adversely impact other water users Collect baseline data before development

37 Extra slides follow

38 Federal Statues: Clean Water Act – Prevents discharges of oil and gas waste to waters of the US with a permit CERCLA – Holds drilling companies accountable for all non- petroleum or natural gas pollution on site Hazardous Materials Transport Act and Hazardous Materials Transportation Uniform Safety Act – Regulates the transport of hazardous fracturing chemicals to the site Endangered Species Act – Functions when working on federal land

39 Local Land Use Issues Restricting well development in scenic areas Requiring stormwater management plans Requiring erosion control plans Setting well spacing requirements Mandating setbacks – Residences – Water bodies – Road ways Setting Noise and Light Standards: – Setting hours of operation in urban areas

40 Water Quality Issues: AR, CO, LA, OH, PA, WY Pit and Tank Storage – Set standards for construction – Ensure compatible fluid or volatile compound containment Spill Prevention* – Require spill prevention and containment pollution plans – Identify chemicals used in hydraulic fracturing Well casing and cementing – Identify and test surrounding water wells before and after fracturing* – Require reporting of well casing and cementing logs * Not required in all States

41 Water Quantity and Disposal Water Management Plans: Ex: Delaware River Basin Commission Fresh Water Report – Obtain water use permit – Identify sources – Create Invasive Species Control Plan – Submit hydrologic report (groundwater) – Obey Pass-by flow guidelines – Record volumes delivered Identify water conservation efforts Waste Water Storage – Store only in enclosed tanks – Test for chemical constituents Waste Water Report Obtain waste disposal permit from approved facility Address all wastewater produced on site Record produced wastewater volumes Record locations and volumes of disposal

42 Hydraulic Fracturing Reporting STRONGER Recommendations: Identification of contaminate migration pathways – Several states require identification and pre-testing of surrounding wells Reporting should be required before and after hydraulic fracturing operations – Notification should allow time for state oversight of operations – Reporting should include Identification of the materials used Aggregate volumes of fracturing fluids Proppant used Continuous logs of fracture pressures

43 Areas for Regulatory Consideration: Truck Traffic Consideration Air Quality Emissions – Gas Production – Diesel Equipment Usage – Fugitive Emissions Chemical Transport Considerations Leasing Issues

44 Well Types: Multiple Horizontal Well Pad Spacing: 640 Acres Disturbance: 4-6 acres StatOilHydro, “Multiple Well Pad Illustration” DOE National Energy Technology Laboratory “Modern Shale Gas Development in the United States: A Primer” Horizontal Well Spacing: 640 Acres Disturb: 3-5 Acres Vertical Well Spacing: 40 Acres Disturb: 2-3 Acres
