A545: With regards to acid gas injection wells and subparts PP and UU, please see the response to EPA-HQ-OAR-2009-0923-0582-31 in the Response to Comments (pages 1474 - 1476) http://www.epa.gov/ghgreporting/documents/pdf/2010/Subpart-W_RTC_part2.pdf.A545. EPA requires reporters to calculate emissions from AGR units and then adjust them downwards by the amount transferred outside of the facility. Therefore, if 100% of the CO2 recovered from an AGR unit is transferred outside of the facility, then CO2 emissions from the AGR unit must be calculated prior to determining the amount being transferred outside the facility. Note that §98.236(c)(3) requires separate reporting of both the AGR emissions and emissions recovered and transferred outside the facility, even if the values are the same.With regards to acid gas injection wells and subparts PP and UU, please see the response to EPA-HQ-OAR-2009-0923-0582-31 in the Response to Comments (pages 1474 - 1476) http://www.epa.gov/ghgreporting/documents/pdf/2010/Subpart-W_RTC_part2.pdf.
