Scope of Model Regulatory Framework. This Model Regulatory Framework for Hydraulically Fractured Hydrocarbon Production Wells (the “MRF”) is intended to assist state governments in implementing a distinct regulatory regime governing subsurface aspects of the drilling, casing, cementing, hydraulic fracturing stimulation, completion and production of onshore hydrocarbon exploration and production wells. The MRF addresses certain regulatory and operational issues pertaining to wellhead control and subsurface wells that are critical to ensuring the integrity of a hydraulically fractured hydrocarbon production well throughout its full life-cycle, beginning with the permitting process and ending with plugging and abandonment. The MRF is intended to apply to all onshore hydraulically fractured hydrocarbon exploration and production wells, regardless of depth or trajectory, but is explicitly not intended to govern and does not address (i) any aspect of injection wells, storage wells or any other type of wells that may also be stimulated via hydraulic fracturing; or (ii) any surface issues such as water use, impoundments, spill control, interagency coordination, surface containment of any well return fluids (including produced fluids generated during flowback, swabbing or other processes), or the off-site transport, recycling or disposal of well return fluids. In addition, certain special considerations relating to the development of coalbed methane resources are not covered by the MRF. 2. Purpose of Model Regulatory Framework . The MRF is based on numerous “best-in-class” state rules and regulations, and incorporates industry best practices with regard to safety, efficiency and environmental protection. The MRF is meant to give state governments a road-map which can be used to implement hydraulic fracturing regulation that: (i) utilizes the structure of currently-effective state laws and regulations; (ii) mandates the use of effective operational industry practices; (iii) encourages technological advances and innovation in order to continually improve industry practices; and (iv) ensures the protection of human health and safety and the environment. Articles I through VII of the MRF contain the substance of the MRF’s requirements, and are chronologically organized based on the life-cycle of a hydraulically fractured hydrocarbon well. These are: (a) ARTICLE I – Definitions (b) ARTICLE II – Well Planning (Permitting); (c) ARTICLE III –Water Sampling; (d) ARTICLE IV – Well Operations – Drilling, Casing and Cementing; (e) ARTICLE V – Well Operations – Completion, Hydraulic Fracturing and Subsequent Well Operations; (f) ARTICLE VI – Well Operations – Production and Well Monitoring; and 1 (g) ARTICLE VII – Plugging and Well Abandonment. 3. Utilizing the Model Regulatory Framework. It is important to note that while the MRF is written in the form of a rule, it is not meant to be an exhaustive scheme to be adopted directly, but instead is a working structure that sets forth key substantive components for effective regulation with regard to the topics and operations covered herein. The reason for this structure is to allow state governments and regulators adequate flexibility in the manner in which they are able to integrate the substantive provisions of the MRF into existing state law. Accordingly, it is expected that in implementing the MRF, state regulators may utilize different terminology, add or expound upon certain procedural requirements,
