Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-34 - Underground Injection Control Program › Section 3745-34-40 - Seismic reflection survey requirements for class I wells

Current through all regulations passed and filed through July 1,
			 2024
(A) A seismic
			 reflection data survey shall be conducted at each injection site where a class
			 I injection well is located or is proposed to be located in order to determine
			 the presence or absence of such geologic faults or fractures as may be
			 identified by seismic reflection survey data within or near the area around the
			 well where the formation pressures may be increased due to the operation of the
			 well.
(B) A new seismic reflection
			 data survey is not required, if a seismic reflection data survey was conducted
			 at an injection site in accordance with a work plan approved by the director or
			 a seismic reflection data survey was conducted at an injection site and the
			 results were approved in writing by the director.
(C) The owner of a class I injection well
			 shall re-evaluate the seismic reflection data collected per paragraph (A) or
			 (B) of this rule, if there is a change in the area of review of an injection
			 well or if the owner or operator is proposing a new well to be located at the
			 injection site. The director may require the owner or operator to submit
			 additional seismic reflection data as may be necessary or appropriate, if the
			 director determines that the existing data are inadequate to determine the
			 presence or absence of geologic faults or fractures as may be identified by
			 seismic reflection survey data within the altered area of review or within the
			 area of pressure buildup of the new well.
(D) Prior to conducting a seismic reflection
			 data survey, the owner or operator shall submit for approval by the director, a
			 work plan detailing the activities and methods to be used to fulfill the
			 requirements of paragraph (A) of this rule. The activities and methods
			 described in the plan shall include those used in data acquisition, processing,
			 interpreting and reporting the seismic reflection data. This work plan shall,
			 at a minimum, include the following:
(1)
			 Provisions for data acquisition, processing, and plotting no less than three
			 seconds of data.
(2) Proposed line
			 locations and appropriate acquisition and processing parameters for the data.
			 The survey shall include adequate horizontal data coverage which will image and
			 properly identify any known or unknown geologic features that may affect the
			 site, both during operation and post-closure periods of the wells.
(3) Provisions for keeping detailed and dated
			 field notes and records of all geophysical investigations.
(4) Provisions for headers on final line
			 plots to indicate the shotpoint ranges of the various energy sources, if
			 multiple energy sources are utilized within a survey. Any changes in shooting
			 or processing parameters utilized should be specified within the headers as
			 well.
(5) Provisions for having
			 lines plotted at an appropriate vertical scale.
(6) Other additional information determined
			 necessary by the director.
