Sec. 2. (a) Except as provided in section 3 of this rule, a storage operator shall file with the department an annual report that includes the following information:

(1) A change to the source or physical, chemical, and other characteristics of the carbon dioxide stream from the data initially provided with the UIC Class VI permit.

(2) The monthly average, highest, and lowest values for injection pressure, flow rate and volume, and annular pressure.

(3) An event that exceeds operating parameters for annulus or injection pressure under the UIC Class VI permit.

(4) An event that triggers a shutoff device and the response to remediate the triggering event.

(5) The annual volume and mass of the carbon dioxide stream injected over the reporting period and the volume injected cumulatively over the life of the project to date.

(6) The results of testing and monitoring required by the United States Environmental Protection Agency for a UIC Class VI permit.

(7) The summarized results of:

(A) the periodic tests of mechanical integrity;

(B) all performed well workovers; and

(C) any other test of the monitoring well or carbon dioxide injection well required by the department.

(8) Updated projections based on actual reservoir operational experience, including geologic data and information. Updated projections under this subdivision refer to the projections for the response and storage capacity of the storage reservoir.

(9) An anomaly in predicted behavior as indicated by the requirements of a carbon sequestration project permit or in the assumptions for which the carbon sequestration project permit is issued must be explained and, if needed, the permit conditions amended under this article.

(10) A summary of any instances of noncompliance with a UIC Class VI permit.

(b) The storage operator shall give the annual report required under subsection (a) to the department not later than sixty (60) days after the end of the calendar year.
