Current through Register Vol. 48, No. 6, March 25, 2025

The Geologic Storage Operator must, at a minimum, provide the following reports to the Director, for each permitted Class VI UIC Well:

a. Form 7CS, Geologic Storage Operator's Monthly Report of Operations. Geologic Storage Operators must report all existing Class VI UIC Wells that are not Plugged and Abandoned on the Form 7CS, Geologic Storage Operator's Monthly Report of Operations within 45 days after the end of each month.

(1) Geologic Storage Operators must report a Class VI UIC Well every month from the month that it is spud until it has been Plugged and Abandoned and reported for one month as abandoned. In addition to their injecting and Plugged and Abandoned Wells, Geologic Storage Operators must identify and list all of their drilling, Shut-In Wells, Suspended Operations, Temporarily Abandoned Wells, and Waiting on Completion Wells on their Form 7CS reports.

(2) Geologic Storage Operators must report each injection formation in a Class VI UIC Well every month from the time that injection begins until it has been abandoned and reported for one month as abandoned.

(3) Geologic Storage Operators must report within 45 days of the end of each month:
A. Monthly average, maximum, and minimum values for injection Pressure, flow rate and volume, and annular Pressure;

B. The monthly volume and/or mass of the Carbon Dioxide Stream injected over the reporting period and the volume injected cumulatively over the life of the project; and

C. Monthly annulus Fluid volume added.

b. Semi-annual reports containing:

(1) Any changes to the physical, chemical, and other relevant characteristics of the Carbon Dioxide Stream from the proposed operating data;

(2) A description of any event that exceeds operating parameters for annulus Pressure or injection Pressure specified in the permit;

(3) A description of any event which triggers a shut-off device required pursuant to Rule 1418.f and the response taken;

(4) The results of monitoring prescribed pursuant to Rule 1420.

c. Report, within 30 days, the results of:

(1) Periodic tests of mechanical integrity pursuant to Rule 418;

(2) Any well workover; and

(3) Any other test of the Injection Well conducted by the Geologic Storage Operator if required by the Director.

d. Report, within 24 hours:

(1) Any evidence that the injected Carbon Dioxide Stream or associated Pressure Front may cause an endangerment to a USDW;

(2) Any noncompliance with a permit condition, or malfunction of the injection system, which may cause Fluid migration into or between USDWs;

(3) Any triggering of a shut-off system (i.e., down-hole or at the surface);

(4) Any failure to maintain mechanical integrity; or

(5) Pursuant to Rule 1420.h for surface air/soil gas monitoring or other monitoring technologies, if required by the Director, any release of Injection Carbon Dioxide to the atmosphere or biosphere.

e. Geologic Storage Operators must notify the Director in writing 30 days in advance of:

(1) Any planned Well workover;

(2) Any planned well Stimulation activities, other than well Stimulation for Formation testing conducted pursuant to Rule 1407; and

(3) Any other planned test of the Injection Well conducted by the permittee.

f. In addition to the Director, Geologic Storage Operators must submit all required reports, submittals, and notifications pursuant to the Commission's 1400 Series Rules to EPA in an electronic format approved by EPA.

g. Records must be retained by the Geologic Storage Operator as follows:

(1) All data collected under Rule 1407 for Class VI permit applications must be retained throughout the life of the Geologic Storage Operations and for 10 years after Site Closure.

(2) Data on the nature and composition of all injected Fluids collected pursuant to Rule 1420.a must be retained until 10 years after Site Closure. The Director may require the Geologic Storage Operator to deliver the records to the Director at the conclusion of the retention period.

(3) Monitoring data collected pursuant to Rule 1420.b-i must be retained for 10 years after it is collected.

(4) Well Plugging reports, Post-Injection Site Care data, and the Site Closure report collected pursuant to requirements at Rule 1423.f and 1423.h must be retained for 10 years after Site Closure.

(5) The Director has authority to require the Geologic Storage Operator to retain any records required in this subpart for longer than 10 years after Site Closure and to require the Geologic Storage Operator to provide such records to the Director.

(6) Unless otherwise specified by the Commission's Rules, Operators must maintain and keep all records, reports, and underlying data required by the Commission's Rules for a period of 5 years after it is collected.
