Most GHGRP reporters will have to use e-GGRT to register facilities or suppliers and submit both the Certificate of Representation and annual greenhouse gas (GHG) reports. If you are subject only to Subpart LL (Suppliers of Coal-based Liquid Fuels) and/or Subpart MM (Supplier of Petroleum Products) then you must use the OTAQREG system to submit you Certificate of Representation report to EPA for those operations. E-GGRT will not support Subpart LL or MM reporting. However, if your facility or supplier is required to report under any other subpart in addition to LL or MM, (for example, stationary combustion), then you will have to register in e-GGRT and submit a separate Certificate of Representation and annual GHG report for those other subparts under e-GGRT.
Q233. Do I have to use e-GGRT to report to the Greenhouse Gas Reporting Program (GHGRP)? Are there any source categories that will not use e-GGRT?
Note: The Cal e-GGRT help system includes general instruction on using the California GHG reporting tool. However, the help system may not explain differences between California and U.S. EPA reporting requirements. Please refer to the ARB reporting website for California-specific reporting requirements and additional help.
