Using e-GGRT to Prepare Your Subpart RR Report

Facilities that conduct geologic sequestration of carbon dioxide (CO2) must report basic information on the amount of CO2 received for injection; develop and implement an EPA-approved monitoring, reporting, and verification (MRV) plan; and report the amount of CO2 sequestered using a mass balance approach and annual monitoring activities.

Major elements of the MRV Plan include:

• Delineation of the monitoring areas
• Identification of potential surface leakage pathways for CO2
• Strategy for detecting and quantifying surface leakage of CO2
• Strategy for establishing the expected baseline for monitoring CO2 surface leakage
• Site-specific variables

Once the facility has an approved MRV Plan, data that are required to be reported annually include:

• Amount of CO2 received, data used to calculate the amount, and the source of the received CO2 (if known)
• Mass balance equation inputs (amounts of CO2 injected, CO2 produced, CO2 emitted by surface leakage, CO2 emitted from equipment leaks and vented CO2 emissions) and the amount of CO2 sequestered
• An annual monitoring report (including a narrative history of the monitoring efforts conducted over the previous calendar year, a description of any changes to the monitoring program, a narrative history of any monitoring anomalies, and a description of any surface leakage of CO₂)

These data should be reported using the Subpart RR reporting module of e-GGRT.

For further detail on reporting Subpart RR data in e-GGRT, you should review the Subpart RR RY16 Webinar.
