Session Law 2012-143 Establishes the Mining and Energy Commission – Modern regulatory oil and gas program with rules for: Well Permitting Well Construction Well Abandonment Wellhead & Site Standards Drilling Units Environmental Sampling Water Use & Management Waste Management & Disposal Chemical Disclosure Hydraulic Fracturing/Stimulation Image courtesy of blog.pubquizusa.com
Mining & Energy Commission Committees Administration of Oil and Gas Committee Environmental Standards Committee Water and Waste Committee Rules Committee Note: The “Fracking Board” does not exist. http://portal.ncdenr.org/web/mining-and- energy-commission/ Photo courtesy of W.T. Haven, 2013
Mining and Energy Commission Study Groups Funding Levels and Potential Funding Sources Local Government Regulation Coordinated Permitting Protection of Trade Secrets and Proprietary Information Compulsory Pooling
Water Acquisition and Management Rule Approved by the Commission Regulates quantity of water withdrawn from groundwater & surface water resources Requires submission of a water use plan Photo courtesy of W.T. Haven, 2013
Well Construction Rule Approved by the Commission Notifications to DENR (cementing, loss of control, etc.) Well casing & cementing standards Well equipment standards Well installation standards Well control & blowout prevention Photo courtesy of R. Channell, 2013
Well Construction Rule Surface casing 100 ft below deepest freshwater zone Cement returned to surface Intermediate casing Cemented from bottom to 200 ft above previous casing string (non water zones) Cemented from bottom to 100 above top of shallowest freshwater zone Image courtesy of Chesapeake Energy: Protecting Groundwater During Natural Gas And Oil Drilling, May 2012
Baseline & Subsequent Testing Rule Draft passed by Commission Testing of water supplies (5,000 ft radius) First round: within 12 months of drilling (full list) Next round: 6 to 12 months after drilling (full list) Subsequent round: 18 to 24 months after construction completion (indicator list) Sampling report sealed by P.E. or P.G.
Full List: pH, specific conductance, total dissolved solids (TDS), turbidity, alkalinity, calcium, chloride, magnesium, potassium, fluoride, sodium, sulfate, arsenic, barium, boron, bromide, chromium, iron, manganese, selenium, strontium, lithium, lead, zinc, uranium, isotopic radium ( 226 Ra and 228 Ra), isotopic strontium ( 87 Sr and 86 Sr), trihalomethanes, benzene, toluene, ethyl benzene, xylenes (BTEX), diesel range organics (DRO), gasoline range organics (GRO), total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAH) (including benzo(a)pyrene), and dissolved methane, propane, and ethane. Indicator List: pH, specific conductance, TDS, chloride, sodium, divalent cations, and dissolved methane, propane, ethane. Baseline & Subsequent Testing Rule
Prohibited Chemical Constituents Rule Approved by the Commission Chemical Abstracts Service (CAS) Numbers Restricts use of diesel fuels in the subsurface US EPA: Permitting Guidance for Oil and Gas Hydraulic Fracturing Activities Using Diesel Fuels – Draft: Underground Injection Control Program Guidance #84
Waste Management Rule Under development with the Water and Waste Management Committee Pits and tanks for management of fluids: – Drilling muds/cuttings, flowback, and produced water Re-use preferred over injection Leak detection for pits Tanks are preferred over pits Final fluids disposal/treatment methods - pending Pit design will require P.E. certification (USFWS Photo by P. Ramirez)
Wellhead Standards Rule Approved by the Mining and Energy Commission Standards for wellhead area (fencing, vegetation, etc.) Standards for wellhead completion (materials, valves, etc.) Photo courtesy of R. Channell, 2013
Well Closure (Draft) Rule Approved by Administration of Oil & Gas Committee Awaiting review by Rules Committee Permanent well abandonment Temporary well abandonment – 5 year period Shut-in status – 1 year period.
Setback (Draft) Rule Under review by Environmental Standards Committee Stakeholder group review completed Research included Alabama, Arkansas, Colorado, Ohio, Pennsylvania, California, Texas, Wyoming, and New York Research included setbacks for other industries in North Carolina
North Carolina Oil and Gas Study under Session Law 2011-276, April 30, 2012, prepared by the North Carolina Department of Environment and Natural Resources and the North Carolina Department of Commerce.
Drilling and Well Construction 10,000 ft. down & horizontal 130 ft. tall 90 ft. drill rods at a time.
Typical Timeline for Installing an Oil or Gas Well Well Pad Construction – 7 to 14 days Drilling Operations – 28 to 35 days Hydraulic Fracturing – 2 to 5 days Brophy, C. & Wolfe, F. 2013, Noise Abatement, Odors, Dust, and Lighting presentation to Environmental Standards Committee, North Carolina Mining & Energy Commission Photo courtesy of www.greglatza.com
