Ohio Administrative Code
Title 3745 - Ohio Environmental Protection Agency
Chapter 3745-34 - Underground Injection Control Program
Section 3745-34-57 - Testing and monitoring requirements
Current through all regulations passed and filed through December 16, 2024
(A) Testing and monitoring requirements for all class I injection wells shall include monitoring of the injected wastes as described in paragraphs (B) to (L) of this rule.
(B) The owner or operator of a class I injection well shall submit a written waste analysis plan to the director for approval that describes the procedures to be carried out to obtain a detailed chemical and physical analysis of a representative sample of the injected waste, including the quality assurance procedures used. The plan shall include the following:
(C) The owner or operator of a class I injection well shall repeat the analysis of the injected wastes as described in the waste analysis plan at sufficient frequencies to yeild representative data of the injection fluids characteristics as specified in the waste analysis plan and when process or operating changes occur that may significantly alter the characteristics of the waste stream.
(D) The owner or operator of a class I injection well shall conduct continuous or periodic monitoring of selected parameters as may be required by the director.
(E) The owner or operator of a class I injection well shall assure that the waste analysis plan remains accurate and the analyses remain representative.
(F) The owner or operator of a class I injection well shall as part of the waste analysis plan submit information demonstrating to the satisfaction of director that the waste stream and its anticipated reaction products will not alter the permeability, thickness or other relevant characteristics of the confining or injection zones such that they would no longer meet the requirements specified in rule 3745-34-51 of the Administrative Code.
(G) The owner or operator of a class I injection well shall as part of the waste analysis plan demonstrate that the waste stream will be compatible with the well materials with which the waste is expected to come into contact, and submit to the director a description of the methodology used to make that determination. Compatibility for purposes of this requirement is established if contact with injected fluids will not cause the well materials to fail to satisfy any design requirement imposed by rule 3745-34-54 of the Administrative Code.
(H) The owner or operator of a class I hazardous waste injection well that injects corrosive waste, or any other waste determined by the director to be potentially interactive with the materials of well construction, shall continuously monitor for corrosion of the construction materials used in the well by doing one of the following:
(I) The owner or operator of a class I hazardous waste injection well that injects corrosive waste, or any other waste determined by the director to be potentially interactive with the materials of well construction, shall implement a corrosion monitoring program including the following:
(J) Mechanical integrity testing.
The owner or operator of a class I hazardous waste injection well shall conduct the mechanical integrity testing required by rule 3745-34-34 of the Administrative Code and approved by the administrator of U.S. EPA as follows:
(K) Monitoring program
(L) The director may require the owner or operator of a class I injection well to submit a seismicity monitoring plan for approval when the director has reason to believe that injection activity may have the capacity to cause seismic disturbances.
