(A) An applicant shall ensure that both of the following apply to the steady state ground water model required under division (C) of section 1521.24 of the Revised Code:
Terms Used In Ohio Code 1521.27
- Aquifer: means a consolidated or unconsolidated geologic formation or series of formations that are hydraulically interconnected and that have the ability to receive, store, or transmit water. See Ohio Code 1521.01
- Ground water: means all water occurring in an aquifer. See Ohio Code 1521.01
- Hydrologic study area: means the area within a four-mile radius from the boundary of the withdrawal area. See Ohio Code 1521.01
- state: means the state of Ohio. See Ohio Code 1.59
- Water resources: means any waters of the state that are available or may be made available to agricultural, industrial, commercial, and domestic users. See Ohio Code 1521.01
(1) It accurately reflects the ground water flow conditions associated with the hydrologic study area and is consistent with American society for testing and materials international standards.
(2) It is in the form of a three-dimensional ground water flow model utilizing finite difference modeling software or other modeling software acceptable to the chief of the division of water resources.
(B) The applicant shall submit the model results in a format prescribed by the chief. The applicant shall include detailed explanations of the hydrologic and geologic parameters used to construct the model, including all of the following:
(1) The saturated thickness of each aquifer;
(2) The elevation of the static water level or potentiometric surface of each aquifer;
(3) Whether each aquifer is confined or unconfined;
(4) The pumping water level elevation at steady state conditions.
