Current through Register Vol. 48, No. 38, September 20, 2024
The owner or operator of a Class VI injection well must, at a
minimum, provide the following reports to the Agency for each permitted Class
VI injection well, as specified in subsection (e):
a) Semi-annual reports containing the
following information:
1) A description of
any deviations in the physical, chemical, and other relevant characteristics of
the carbon dioxide stream from the proposed operating data submitted to the
Agency pursuant to Sections
730.182(a)(7)
and (c)(3) and
730.186(b)(1)
and (c)(3);
2) The monthly average, maximum, and minimum
values for injection pressure, flow rate and volume, and annular
pressure;
3) A description of any
event that exceeds operating parameters for the annulus pressure or injection
pressure specified in the permit;
4) A description of any event that triggers a
shut-off device required pursuant to Section
730.188(e)
and the response undertaken by the owner or operator;
5) The monthly volume or mass of the carbon
dioxide stream injected over the reporting period and the volume injected
cumulatively over the life of the project;
6) The monthly annulus fluid volume added;
and
7) The results of the
monitoring required by Section
730.190.
b) Report the results within 30
days after completion of any of the following:
1) Any results of periodic tests of
mechanical integrity;
2) Any well
workover; and
3) Results of any
other test of the injection well that the owner or operator has conducted as
required by the Agency.
c) Report any of the following events within
24 hours after the event:
1) The owner or
operator has discovered any evidence that the injected carbon dioxide stream or
associated pressure front may cause an endangerment to a USDW;
2) The owner or operator has discovered any
noncompliance with a permit condition, or malfunction of the injection system,
which may cause fluid migration into or between USDWs;
3) The owner or operator has discovered any
triggering of a shut-off system (i.e., down-hole or at the surface);
4) The owner or operator has discovered any
failure to maintain mechanical integrity; or
5) The owner or operator has discovered any
release of carbon dioxide to the atmosphere or biosphere through surface air or
soil gas monitoring or other monitoring technologies that the Agency has
required pursuant to Section
730.190(h).
d) An owner or operator must
notify the Agency in writing 30 days in advance of any of the following:
1) Any planned well workover;
2) Any planned stimulation activities, other
than stimulation for formation testing conducted pursuant to Section 730.182;
and
3) Any other planned test of
the injection well conducted by the owner or operator.
e) In corresponding
40 CFR
146.91(e), USEPA has stated
that owners or operators must submit all required reports, submittals, and
notifications under this Subpart H to USEPA in an electronic format approved by
USEPA.
f) The owner or operator
must retain records as follows:
1) The owner
or operator must retain all data collected pursuant to Section
730.182
for Class VI permit applications throughout the life of the geologic
sequestration project and for 10 years following site closure.
2) The owner or operator must retain data on
the nature and composition of all injected fluids collected pursuant to Section
730.190(a)
until 10 years after site closure. The Agency may require the owner or operator
to deliver the records to the Agency at the conclusion of the retention
period.
3) The owner or operator
must retain monitoring data collected pursuant to Section
730.190(b)
through (i) for 10 years after it is
collected.
4) The owner or operator
must retain well plugging reports, post-injection site care data, including, if
appropriate, data and information used to develop the demonstration of the
alternative post-injection site care timeframe, and the site closure report
collected pursuant to requirements at Section
730.193(f)
and (h) for 10 years following site
closure.
5) The Agency may require
the owner or operator to retain any records required by this Subpart H for a
period that is longer than 10 years after site closure. Any Agency requirement
that the owner or operator retain records for a longer period must be made in
writing, the writing must recite a definite longer period, and the Agency must
state the reasons for the determination to require the longer period. An owner
or operator may appeal any Agency determination made pursuant to this
subsection (f)(5) to the Board pursuant to Section 40 of the Act.
