Ohio Administrative Code
Title 3745 - Ohio Environmental Protection Agency
Chapter 3745-34 - Underground Injection Control Program
Section 3745-34-38 - Operating, monitoring, and reporting requirements for class I wells
Universal Citation: OH Admin Code 3745-34-38
Current through all regulations passed and filed through March 18, 2024
(A) Operating requirements. Operating requirements shall, at a minimum, include:
(1) Except during stimulation, injection
pressure at the wellhead shall not exceed a maximum which shall be calculated
so as to assure that the pressure in the injection zone during injection does
not initiate new fractures or propagate existing fractures in the injection
zone. In no case shall injection pressure initiate fractures in the confining
zone or cause the movement of injection or formation fluids into an underground
source of drinking water.
(2)
Injection between the outermost casing protecting underground sources of
drinking water and the well bore is prohibited.
(3) Unless an alternative to a packer has
been approved under paragraph (C) of rule
3745-34-37
of the Administrative Code, the annulus between the tubing and the long string
of casings shall be filled with a fluid approved by the director, and a
pressure, also approved by the director, shall be maintained on the annulus.
(B) Monitoring requirements. Monitoring requirements shall, at a minimum, include:
(1) The analysis of the injected fluids with
sufficient frequency to yield representative data of their characteristics; and
(2) Installation and use of
continuous recording devices to monitor injection pressure, flow rate and
volume, and the pressure on the annulus between the tubing and the long string
of casing; and
(3) A demonstration
of mechanical integrity pursuant to rule
3745-34-34
of the Administrative Code every three years during the life of the well or
more frequently, if public health, safety, or environmental circumstances so
warrant; and
(4) Pressure testing
of the entire casing length every three years during the life of the well or
more frequently, if public health, safety, or environmental circumstances so
warrant, instead of using as the standard a pressure of fifty per cent greater
than the average pressure; and
(5)
The type, number and location of wells within the area of review to be used to
monitor any migration of fluids into and pressure in the underground sources of
drinking water, the parameters to be measured and the frequency of monitoring.
(C) The director may require the owner or operator to submit, for approval, a monitoring program plan which meets the requirements set forth in rule 3745-34-57 of the Administrative Code.
(D) Reporting requirements. Reporting requirements shall, at a minimum, include:
(1) Monthly reports to the director on:
(a) The physical, chemical and other relevant
characteristics of injection fluids; and
(b) Monthly average, maximum and minimum
values for injection pressure, flow rate in GPM and volume, and annular
pressure. For each minimum and maximum injection rate reported, list in the
report the injection pressure and annulus pressure occurring during the time
the well was operating at this minimum or maximum rate. Also include a listing
of the date, duration and cause of any non-operating period for each well
during the month; and
(c) The
results of monitoring prescribed under paragraph (B)(5) of this rule.
(2) Reporting the
results, with the first monthly report after the completion, of:
(a) Periodic tests of mechanical integrity;
and
(b) Any other test of the
injection well conducted by the permittee if required by the director; and
(c) Any well work over.
(3) Any procedures conducted at
the injection well other than routine operational procedures.
