Water Resources Management & Shale Gas Development in the Susquehanna River Basin: The Lessons Thus Far Environmental Sustainability Panel Widener University School of Law September 27, 2013 Thomas W. Beauduy SRBC Special Counsel About the Commission • • • • • Federal-Interstate Compact Commission Established in 1971 for 100 years Jurisdictions: NY, PA, MD and US Forum for the Exercise of Joint Sovereignty Responsibility to Manage the Water Resources of the Basin • Role of Member Jurisdictions What Does SRBC Regulate? • • • • • Surface Water Withdrawals: 100,000 gpd Threshold Groundwater Withdrawals: 100,000 gpd Threshold Consumptive Use: 20,000 gpd Threshold Diversions: Thresholds - Any Amt. In; 20,000 gpd Out For Unconventional Natural Gas Industry, all Regulatory Thresholds are Set at Gallon One Major Regulatory Changes Related to Shale Gas Development • • • • • Existing regulatory scheme didn’t quite fit Water use patterns highly decentralized Short-term nature of projects Multiple withdrawals/sources for multiple pad sites Headwaters - historically least developed portions of basin • Withdrawals spatially disassociated with consumptive use activity Major Regulatory Changes Related to Shale Gas Development • • • • • • • Prudence dictated a gallon one threshold All water use is considered consumptive Management of CU on a drilling pad basis Approval by Rule Four regulatory modification packages in 5 years Rigor associated with recordkeeping and reporting Emergence of a water use profile Major Regulatory Changes Related to Shale Gas Development (Cont.) • • • • • Post-hydrofracture reporting Water sharing: registration of approved sources Master source list approach - reporting Source approvals (PWS) - coordination Flowback: reuse, pad-to-pad transfers (including interbasin) • Wastewater, lesser quality waters source approvals Marcellus – Basin Water Use Profile (July 1, 2008 thru June 30, 2013) • 2,312 Unconv. Gas Wells Hydrofractured • 12.2 billion gallons of water consumptively used • 9.39 billion gallons of water withdrawn from docketed sources • 3.0 billion gallons of water withdrawn from other approved sources (primarily PWS) Marcellus – Basin Water Use Profile (July 1, 2008 thru June 30, 2013) (Cont.) • 4.5 million gallons (ave.) used per well for hydrofracturing (84% freshwater, 16% flowback reused). • 8% - 10% of injected water is recovered as flowback within first 30 days after release of pressure. • 87% of water brought on-site is used, balance of 13% temporarily stored on site, or transferred to another site. Sustainability Issues • At basin scale, location more important than amounts of withdrawals • Timing and location of withdrawals is key • Cumulative impacts • Use of passby restrictions (interruptible sources) to minimize impacts on aquatic ecosystems during low flow periods Cumulative Water Use and Availability Study • Study is underway • Quantify consumptive use at a watershed scale • Determine water availability at a watershed scale • GIS-based water use & availability assessment tool The End Game • Determining water availability at a watershed scale requires scientific rigor, but it may well be the easy part. • Establishing sustainable limits for water development and protection of instream flow needs will present challenges. • Challenges will be legal, political and social. • Shale gas development not the driver, but… Toward Water Resource Sustainability • • • • • Follow the science Practice adaptive management Responsive, adaptive regulatory scheme Low flow protection Cumulative water use availability & assessment • Vigilance in monitoring impacts
