WATER MANAGEMENT PLANSJan 12, 2010 Susan K. Weaver, P.E. Division Chief, Water Use Planning PA DEP
PA Laws and Regulations • Laws • Oil and Gas Act • Clean Streams Law • Water Resources Planning Act • Regulations • Chapter 78 • Chapters 93 and 96 • Chapter 110
Water Management Plan (WMP) • The Department issues gas permits under the Oil and Gas Act which requires compliance with other laws administered by DEP. • The Department requires a demonstration, through the submission and approval of a Water Management Plan in connection with the gas well permit, that the gas well operator's withdrawal and use of water sources in the Commonwealth in connection with natural gas well development will not violate the Clean Streams Law's admonition against pollution.
Statewide Implementation • WMP process to provide framework for statewide consistency • DEP using the SRBC Passby Flow Guidelines statewide • Working closely with River Basin Commission staff
Purpose of WMP • The development of a plan that identifies various water sources proposed to be used for utilization in development of Marcellus Shale Natural Gas Wells within the covered area. • Allow operator flexibility to update the plan as needed.
River Basin Commission Interaction • To reduce duplication, if a water source is subject to approval by SRBC or DRBC, the River Basin Commission approvals will be captured in a Water Management Plan and submitted to DEP. • The Department will rely upon the information gathered, data analyses performed and expertise of the SRBC and DRBC regarding the proposed water source but will reserve for itself the ultimate decision and exercise its independent judgment concerning whether or not to approve the Water Management Plan.
WMP Content • Municipal and county notification • Identification of sources • Water Source and Use Monitoring Plan • Registration and Reporting
WMP Content(continued) • 48-hour source initiation notice prior to first withdrawal • Assessment of impact to environment • Low flow analysis • PNDI • Identification of PWSAs
WATER SOURCES • Public Water Supplies • Surface Water or Groundwater • Wastewater, Mine Water, Cooling Water Discharge • Reuse of flowback
Water Source and Use Monitoring Plan • Accurate monitoring of the amount of water withdrawn on a daily basis • Daily recording and maintenance of data • Water withdrawal data to be maintained for five years and be available to DEP for review upon request. • Passby Flow Monitoring if required
Registration and Reporting • All sources must be registered • Quarterly submittal of Sub Facility Reports using the DEP Greenport • Annual submittal of Primary Facility Reports using DEP Greenport- still on hold
Surface Water Sources • Rivers • Streams • Lakes • Large Ponds
Surface Water • Location • Stream Classification- Special Protection Water (High Quality or Exceptional Value) • Low Flow Conditions - Q7-10 • Is 10% of the Q7-10 economically viable • Storage Location
Q 7-10 • Low Flow Condition • Flow rate that occurs for 7 consecutive days during a 10-year period (Q7-10) at the proposed intake location. • In many cases, permissible amount 10% of Q7-10 • Example – A point on the Susquehanna River has a Q7-10 of 0.155 mgd (determined from StreamStats). Proposed maximum instantaneous rate of withdrawal would be 0.0155 mgd.
Surface Water • Pass by Flow • 20% of average daily flow withdraw • Existing upstream or downstream gauging stations • USGS or other established gauging systems • Fixed water level marker (mark on a bridge)
Groundwater • Location • Droughts • Stream Impact • Hydrogeologist • Groundwater Characterization • Ownership of the Well • PADEP Time frame ~6 months
Other Water Sources • Wastewater • Leachate from Landfill • POTW Effluent • Mine Water • AMD • Cooling Water Discharge • Reuse of flowback
Emerging Issues • Working with USACE to define “area of influence” around USACE reservoirs • Management of Aquatic Invasive Species • Revision to DEP Well Site Restoration Report underway to capture similar information to SRBC Post-Hrdrofracture Stimulation Report
