Ohio Administrative Code › Title 1501:9 - Division of Mineral Resources Management - Oil and Gas › Chapter 1501:9-7 - Solution Mining Projects › Section 1501:9-7-08 - Construction of solution mining projects

Current through all regulations passed and filed through July 1, 2024
(A) The following construction, testing, and
			 monitoring requirements shall apply to any well permitted and drilled after the
			 effective date:
(1) Surface casing shall be
			 free of apparent defects, set at least fifty feet below the deepest underground
			 source of drinking water, and sealed by circulating cement to the surface under
			 the supervision of the division. In the event cement fails to circulate to the
			 surface, the division may approve a remedial course of action.
(2) Intermediate casing or casings, if
			 required, shall be set and sealed as approved by the chief. Centralizers may be
			 required.
(3) The production or
			 long string of casing shall be set and cemented as approved by the chief.
			 Centralizers may be required.
(4)
			 Tubing may be required for use in injection and withdrawal operations. The
			 operator shall furnish to the chief evidence that the casing will not be
			 exposed to undue corrosion. Installation of a packer on the tubing may be
			 required.
(5) Hole diameters,
			 casing weights and diameters, and cementing procedures shall be subject to
			 approval by the chief.
(6) To
			 verify the quantity of cement used and quality of the cement bond, a cement
			 bond log and/or other logs required by the chief, shall be run in addition to
			 the cementing records.
(7) Each
			 solution mining project owner or his agent shall give the appropriate division
			 inspector reasonable notice in advance of cementing, placing and removing of
			 casing, installation of tubing and packer, and initial operation. A division
			 office shall be notified when the appropriate inspector cannot be contacted.
			 Said work shall be done pursuant to the instructions of a representative of the
			 division in accordance with Chapter 1509. of the Revised Code and Chapter
			 1501:9-7 of the Administrative Code.
(8) Appropriate logs and other tests shall be
			 conducted for new solution mining wells. A descriptive report interpreting the
			 results of such logs and tests shall be prepared by a knowledgeable log analyst
			 and submitted to the chief. The logs and tests appropriate to each type of
			 solution mining well shall be determined based on the intended function, depth,
			 construction, and other characteristics of the well; availability of similar
			 data in the area of the drilling site; and the need for additional information
			 that may arise as the construction of the well progresses.
(9) For new solution mining projects, the
			 following information concerning the injection zone shall be determined or
			 calculated when the injection zone is a water bearing formation:
(a) Fluid pressure;
(b) Fracture pressure; and
(c) Physical and chemical characteristics of
			 the formation fluids.
(10) When the injection formation is not a
			 water bearing formation, the information in paragraph (A)(9)(b) of this rule
			 must be submitted.
(11) When the
			 injection wells penetrate an underground source of drinking water in an area
			 subject to subsidence or catastrophic collapse, an adequate number of
			 monitoring wells shall be completed into the underground source of drinking
			 water to detect any movement of injected fluids, process by-products, or
			 formation fluids into the underground source of drinking water. The monitoring
			 wells shall be located outside the physical influence of the subsidence or
			 catastrophic collapse.
(12) In
			 determining the number, location, construction, and frequency of monitoring of
			 the monitoring wells, the following criteria shall be considered:
(a) Population relying on the underground
			 source of drinking water affected or potentially affected by the injection
			 operations;
(b) Proximity of the
			 injection operation to points of withdrawal of drinking water;
(c) Local geology and hydrology;
(d) Operating pressures and whether a
			 negative pressure gradient is being maintained;
(e) Nature and volume of the injected fluid,
			 the formation water, and the process by-products; and
(f) Injection well density.
