# 98.486 Data reporting requirements.
In addition to the information required by § 98.3(c), the annual report shall contain the following information, as applicable:
(a) The annual quantity of associated storage in metric tons of CO<sub>2</sub> (*m*<sub>stored</sub>).
(b) The density of CO<sub>2</sub> if volumetric units are converted to mass in order to be reported for annual quantity of CO<sub>2</sub> stored.
(c) The annual quantity of CO<sub>2</sub> input (*m*<sub>input</sub>) and the information in paragraphs (c)(1) and (2) of this section.
(1) The annual total mass of CO<sub>2</sub> received at the custody transfer meter by the CO<sub>2</sub>-EOR project, including CO<sub>2</sub> transferred from another CO<sub>2</sub>-EOR project (*m*<sub>received</sub>).
(2) The annual mass of native CO<sub>2</sub> produced and captured in the CO<sub>2</sub>-EOR project (*m*<sub>native</sub>).
(d) The annual mass of CO<sub>2</sub> that is recycled and reinjected into the EOR complex.
(e) The annual total mass of CO<sub>2</sub> loss from project operations (*m*<sub>loss operations</sub>), and the information in paragraphs (e)(1) through (4) of this section.
(1) Loss of CO<sub>2</sub> due to leakage from production, handling, and recycling CO<sub>2</sub>-EOR facilities (infrastructure including wellheads) (*m*<sub>loss leakage facilities</sub>).
(2) Loss of CO<sub>2</sub> from venting/flaring from production operations (*m*<sub>loss vent/flare</sub>).
(3) Loss of CO<sub>2</sub> due to entrainment within produced gas/oil/water when this CO2 is not separated and reinjected (*m*<sub>loss entrained</sub>).
(4) Loss of CO<sub>2</sub> due to any transfer of CO<sub>2</sub> outside the CO<sub>2</sub>-EOR project (*m*<sub>loss transfer</sub>).
(f) The total mass of CO<sub>2</sub> loss from the EOR complex (*m*<sub>loss EOR complex</sub>).
(g) Annual documentation that contains the following components as described in Clause 4.4 of CSA/ANSI ISO 27916:19 (incorporated by reference, see § 98.7):
(1) The formulas used to quantify the annual mass of associated storage, including the mass of CO<sub>2</sub> delivered to the CO<sub>2</sub>-EOR project and losses during the period covered by the documentation (see Clause 8 and Annex B of CSA/ANSI ISO 27916:19 (incorporated by reference, see § 98.7)).
(2) The methods used to estimate missing data and the amounts estimated as described in Clause 9.2 of CSA/ANSI ISO 27916:19 (incorporated by reference, see § 98.7).
(3) The approach and method for quantification utilized by the operator, including accuracy, precision, and uncertainties (see Clause 8 and Annex B of CSA/ANSI ISO 27916:19 (incorporated by reference, see § 98.7)).
(4) A statement describing the nature of validation or verification including the date of review, process, findings, and responsible person or entity.
(5) Source of each CO<sub>2</sub> stream quantified as associated storage (see Clause 8.3 of CSA/ANSI ISO 27916:19 (incorporated by reference, see § 98.7)).
(6) A description of the procedures used to detect and characterize the total CO<sub>2</sub> leakage from the EOR complex.
(7) If only the mass of anthropogenic CO<sub>2</sub> is considered for mstored, a description of the derivation and application of anthropogenic CO<sub>2</sub> allocation ratios for all the terms described in Clauses 8.1 to 8.4.6 of CSA/ANSI ISO 27916:19 (incorporated by reference, see § 98.7).
(8) Any documentation provided by a qualified independent engineer or geologist, who certifies that the documentation provided, including the mass balance calculations as well as information regarding monitoring and containment assurance, is accurate and complete.
(h) Any changes made within the reporting year to containment assurance and monitoring approaches and procedures in the EOR operations management plan.
